Bariyatrik Cerrahi Öncesi ve Sonrası Biyokimyasal Bulguların Değerlendirilmesi: Bir Bakü Örneği
No full textObezite, anormal veya aşırı yağ birikimi ile karakterize edilen karmaşık bir metabolik hastalık olup, küresel olarak artmaya devam etmekte ve önemli sağlık ve ekonomik etkiler yaratmaktadır. Son veriler, dünya genelinde yetişkinlerin %43'ünün hafif şişman, %16'sının ise obez sınıfına girdiğini göstermekte, etkili müdahalelere ihtiyaç duyulduğunu ortaya koymaktadır. Bariyatrik cerrahi (BC), özellikle yaşam tarzı değişikliklerine dirençli vakalarda, morbid obezitenin tedavisinde önde gelen bir yöntem olarak ortaya çıkmıştır. Bununla birlikte, bariyatrik cerrahi, demir, hemoglobin, B12 vitamini, D vitamini, açlık kan glikozu ve Hemoglobin A1C gibi hayati öneme sahip mikro besin ögelerinde yetersizliklere sebep olarak beslenme açısından çeşitli zorluklar doğurabilmektedir. Bu çalışma, Azerbaycan'ın Bakü kentindeki bariyatrik cerrahi hastalarından oluşan bir grupta, ameliyat öncesi ve sonrasında demir, hemoglobin, B12, D vitamini, açlık kan glikozu ve Hemoglobin A1C seviyelerini değerlendirmektedir. Araştırmada, ameliyat sonrası komplikasyonları azaltmak ve hasta sonuçlarını iyileştirmek için beslenme yönetimi stratejilerinin etkinliği de incelenmiştir. Retrospektif analiz kapsamında serum demir, ferritin, hemoglobin, 25-hidroksivitamin D ve B12 vitamini seviyeleri gibi biyokimyasal bulguların değerlendirmeleri yapılmıştır. Roux-en-Y gastrik bypass (RYGB) veya sleeve gastrektomi (SG) prosedürüne tabi tutulmuş hastalardan ameliyat öncesi ve ameliyat sonrası üç, altı ve on iki aylık takip süreçlerinden elde edilen verileriler toplanmıştır. Sonuçlar, mikro besin öğesi eksikliklerinin ameliyat öncesinde yaygın olduğunu ve en sık demir ile D vitamini eksikliklerinin görüldüğünü ortaya koymuştur. Ameliyat sonrası dönemde bu eksikliklerin artış gösterdiği gözlemlenmiştir. Bu eksikliklere sebep olan faktörler arasında değişen gastrointestinal anatomi, azalan diyet alımı ve malabsorpsiyon yer almaktadır. Hemoglobin seviyelerinde, erken ameliyat sonrası dönemde, azalmış demir depoları ve yetersiz besin alımı ile ilişkili olarak anlamlı bir düşüş gözlemlenmiştir. Benzer şekilde, B12 vitamini seviyeleri ciddi şekilde etkilenmiş ve uzun dönem nörolojik ve hematolojik komplikasyonları önlemek için takviye gerektirmiştir. D vitamini seviyeleri mevsimsel varyasyonlar göstermiş ve kış aylarında eksiklikler daha da artmıştır. Çalışma, bireyselleştirilmiş, multidisipliner bir beslenme yönetiminin önemini vurgulayarak rutin biyokimyasal izleme ve uygun takviyelerle zamanında müdahale edilmesini önermektedir. Öneriler, ameliyat öncesi beslenme optimizasyonunun başlatılması, hastaya özel takviye protokollerinin uygulanması ve yapılandırılmış eğitim programları aracılığıyla hasta uyumunun artırılmasını kapsamaktadır. Bu araştırma, BC hastalarının bakım sürecinde diyetisyenlerin ve sağlık ekiplerinin kritik rolünü bir kez daha gözler önüne sermektedir. Mikro besin eksikliklerinin proaktif olarak ele alınması, sadece ameliyat sonrası komplikasyonları azaltmakla kalmaz, aynı zamanda genel yaşam kalitesini ve uzun vadeli cerrahi başarıyı da artırır. Bulgular, standart rehberler geliştirilmesi ve BC hastalarının yönetiminde klinik uygulamaların iyileştirilmesi için değerli bilgiler sağlamaktadır.Obesity, a complex metabolic disorder characterized by abnormal or excessive fat accumulation, continues to rise globally, with significant health and economic implications. Recent data indicates that over 43% of adults worldwide are overweight, and 16% are classified as obese, necessitating effective interventions. Bariatric surgery has emerged as a leading treatment modality for morbid obesity, particularly in cases resistant to lifestyle modifications. Despite its efficacy in weight loss and improving comorbid conditions, bariatric surgery poses nutritional challenges, including deficiencies in key micronutrients such as iron, haemoglobin, vitamin B12, and vitamin D. This study focuses on a cohort of bariatric surgery patients in Baku, Azerbaijan, assessing the pre-and post-operative levels of iron, haemoglobin, B12, vitamin D, Glucose and HbA1c. The research also evaluates the effectiveness of nutritional management strategies designed to mitigate post-operative complications and improve patient outcomes. The retrospective analysis involved comprehensive biochemical assessments, including serum iron, ferritin, haemoglobin, 25-hydroxyvitamin D, and vitamin B12 levels. Data was collected from patients who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) procedures. The dataset encompasses preoperative information as well as postoperative follow-up records at three, six, and twelve months. The results revealed that pre-operative deficiencies in micronutrients were prevalent, with iron and vitamin D deficiencies being the most common. Post-operatively, the prevalence of these deficiencies increased, particularly in patients undergoing RYGB. Factors contributing to these deficiencies included altered gastrointestinal anatomy, reduced dietary intake, and malabsorption. Haemoglobin levels significantly declined in the early postoperative period, correlating with decreased iron stores and suboptimal nutritional intake
Banking Authority Role in Improving Governance and Risk Management: Analysis on the Failure of Silicon Valley, Silvergate and Signature Banks
No full textÖzet Aşağıdaki tez, bankacılık otoritelerinin bankacılık yönetimini geliştirmedeki önemini, özellikle ABD'deki üç banka, yani Silvergate, Signature ve Silicon Valley bankaları örneğine odaklanarak ve bu otoritelerin çeşitli risk yönetimi kısıtlamalarını ve faktörlerini nasıl aşmaya çalıştıklarını analiz ederek güçlendirmeye çalışacaktır. Bankaların iflas ve finansal kriz vakalarının artması, sektördeki herhangi bir finansal şoka karşı hazırlığı hızlandırmak için etkili risk yönetimi önlemlerinin ve sağlam yönetimin önemini haklı çıkarmaktadır. Çalışma üç hipotez tarafından yönlendirilmektedir: bağımsız yönetim kurulu üyeleri alınan kararlarda ve denetimde etkilidir; güçlü kredi-it risk kontrolü kredi riskini azaltır; ve iyi yönetilen piyasa riskleri, büyük risklere sahip finansal piyasalardaki dalgalanmaları yönetmeye yardımcı olur. Bazı önemli noktalar arasında Credit Suisse bankasının diğer çöküşüne odaklanılması da yer almaktadır. Bu bankaların yönetim ve risk profillerini araştırmak için tez, temel finansal performans ve risk göstergelerini kapsayan analitik bir çerçeve kullanmaktadır: ROA, ROE, Z-puanı, NPL'ler, ROA sapması ve gerçek brüt kazanç endeksi. Bu yönler, seçilen bankaların finansal performansını, üretkenliğini ve kırılganlığını değerlendirmek için analiz edilir. Ayrıca, Federal Mevduat Sigorta Kurumu'nun (FDIC) dağıtımı da bu araştırmaya dahil edilmiştir. Bir vaka çalışması metodolojisi kullanarak, tez uyum derecesini ölçer ve nicel veri analizi yaparak düzenleyici önlemlerin kullanılmasının riskleri ve etkinliği üzerinde tartışır. Bu makale, belirli yönetişim yapılarının ve risk yönetimi uygulamalarının bu bankaların istikrarını ve performansını nasıl etkilediğini tartışarak düzenleyiciler ve sektör için içgörüler sağlar. Bu çalışma, bankacılık yönetişimi ve risk yönetimi alanındaki mevcut bilgiye katkıda bulunarak bankacılık kültürünü güçlendirmek için bir dizi öneri sunar. Yönetişim, finansal sürdürülebilirlik ve düzenleme arasındaki ilişkiye odaklanılması nedeniyle, çalışma ayrıca gelişen finansal ortamda ortaya çıkan risklere yanıt vermek için gelişen ve titiz yaklaşımlara olan ihtiyacı vurgular.The following thesis will attempt to reinforce the significance of banking authorities in enhancing banking governance, particularly focusing on the case of three banks in the U.S, namely Silvergate, Signature and Silicon Valley banks, and analyzing how those authorities have sought to overcome the various risk management constraints and factors. The rising cases of banks' failure and financial crises justify the importance of effective risk management measures and sound governance to prompt preparedness for any financial shocks in the industry. The work is guided by three hypotheses: independent board members are effective in the decisions made and supervision; strong cred-it risk control decreases credit risk; and well-managed market risks help in managing fluctuations in financial markets that have great risks. Some of the highlights have also included focused on the other collapse of Credit Suisse bank. To investigate the governance and risk profiles of these banks, the thesis employs an analytical framework encompassing key financial performance and risk indicators: ROA, ROE, Z-score, NPLs, deviation of ROA and real gross earnings index. These aspects are analyzed to assess the financial performance, productivity and vulnerability of the chosen banks. Besides, apportionment of Federal Deposit Insurance Corporation (FDIC) has also been incorporated in this research. Using a case study methodology, the thesis measures the degree of compliance and argues over the risks and effectiveness of using regulatory measures by conducting quantitative data analysis. This paper discusses how certain governance structures and risk management practices have affected the stability and performance of these banks providing insights for the regulators and the industry. This work adds to the existing knowledge in the area of banking governance and risk management offering a number of recommendations to strengthen the banking culture. Due to the provided focus on the relation between governance, financial sustainability, and regulation, the study also emphasizes the need for evolving and rigorous approaches to respond to the emerging risks in the evolving financial environment
Preservation of Septal Cartilage for Early Revisions: A Histopathological Study
No full textCelik, Cem/0000-0002-8538-2081Objective To determine how storage medium and temperature affect the histological viability of autologous septal cartilage intended for early revision rhinoplasty. Methods Cartilage specimens stored for 6 and 12 months in four media-dry, gentamicin, cefazolin, and saline-at two distinct temperatures underwent histopathological evaluation after paraffin embedding. The assessed parameters were graft viability, fibrosis, osteoid metaplasia, and peripheral chondroid proliferation. Results Among 480 septal cartilage specimens harvested from 30 patients, overall viability fell from 62 +/- 15% at 6 months to 44 +/- 14% at 12 months (p < 0.001), while fibrosis, osteoid metaplasia, and peripheral chondroid proliferation all increased significantly (each p < 0.001). Viability declined in every storage condition, but grafts kept at - 80 degrees C or in saline-based solutions deteriorated fastest, reaching a mean viability of 39% versus 53% for dry storage at - 20 degrees C at 12 months. Multivariate analysis confirmed - 80 degrees C storage (OR 2.3, 95% CI 1.4-3.8) and saline media (OR 1.9, 1.1-3.4) as independent predictors of poor viability (< 40%), whereas antibiotic additives were not protective. Histological evidence of osteoid metaplasia (OR 3.6, 1.9-6.8) and peripheral chondroid proliferation (OR 2.1, 1.2-3.7) strongly predicted non-viable grafts. A linear mixed-effects model demonstrated additive negative effects of - 80 degrees C and saline on both baseline viability and its rate of decline (marginal R-2 = 0.52). Dry storage at - 20 degrees C yielded the most favorable long-term viability. Conclusion Dry storage of autologous septal cartilage at - 20 degrees C preserves graft viability well enough to offer a cost-effective alternative for early revision surgeries, warranting confirmation in prospective clinical trials.Science Citation Index Expande
Pharmacists’ Role in Cost Saving and Waste Minimization Study on Antineoplastic Drugs: A Multi-Central Study in Turkey
No full textCancer diseases are the most common cause of death and chemotherapeutics used in cancer treatment have an important place in the budget allocated to health due to their high costs. This study aims to reduce disposal costs and reduce chemotherapy drug expenses through cost savings. Our study was conducted between November 2017 and July 2018 (1st semester) and between August 2018 and April 2019 (2nd semester) in three hospitals using a common chemotherapy drug preparation center. Chemotherapy sessions were rearranged in accordance with the drugs included in the treatment plans to reduce drug costs. The drug quantities billed through hospital automation programs and the disposal costs of unused drugs were reported by the pharmacists on a milligram (mg) basis. The obtained data was analyzed by the GraphPad Prism program. P<0.05 was considered significant. While the total amount of waste medicine in the 1st. period was reported as 371,866 mg, it was reported as 303,056 mg in the 2nd. period (p<0.05). While the total disposal cost was calculated at € 87,867.02 in the 1st. period, it was calculated € 26,392.48 in the 2nd. period under the control of pharmacists (p<0.01). In this study, it was observed that providing and monitoring drug preparation services by well-equipped pharmacists specialized in the field of oncology gave positive results in terms of reducing both drug expenditures and drug disposal costs. Further studies are needed to determine the safety of chemotherapy pharmacists and patients.Emerging Sources Citation Inde
The Relationship Between Physical Performance with Dual-Task Performance in Geriatric Individuals
No full textObjective: Maintaining functional independence in older adults requires an intricate balance between physical and cognitive abilities. While physical performance is known to support overall health, its relationship with dual-task performance-an essential component of daily life activities-remains a critical area of investigation. This study aimed to investigate the association between physical performance and dual-task performance and to compare the effects of different levels of physical performance on dual-task execution in geriatric individuals. Materials and Methods: A total of 79 geriatric individuals (mean age=68.68 +/- 4.42) were included in the study. Their physical performances were evaluated through the Alusti test, Timed Up and Go test (TUGT), 30-Second Sit-to-Stand test (30s STST) and 10-meter Walk test. Dual-task performance measurements were assessed using the TUGT, 30s STST and 10-meter Walk test (using motor and cognitive task) and the dual-task questionnaire. Results: There was a low correlation between the Alusti test and Dual-task scale (r=-0.222; p=0.048), while a moderate-level correlation between TUGT (r=0.339; p=0.001), 30s STST (r=-0.336; p=0.002), and the 10-meter Walk test (r=0.365; p=0.001). When individuals were divided into two groups based on Alusti test scores (good mobility and very good mobility), the mean of 30s STST motor and-cognitive tasks were statistically significantly higher in the very good mobility group compared to good mobility (p=0.026, p=0.005; respectively). Conclusion: The findings suggest that dual-task performance is closely linked to physical function in older adults, with higher physical performance associated with improved dual-task execution. Given the increasing importance of maintaining cognitive-motor abilities for aging populations, targeted physical activity interventions may help mitigate declines in dual-task performance, ultimately promoting safer mobility and greater independence in daily life. Future research should further explore the mechanisms underlying these interactions to develop effective strategies for cognitive-motor preservation in geriatric care.Emerging Sources Citation Inde

A Method for Correcting the Substructure of Multiprong Jets Using the Lund Jet Plane
No full textMany analyses at the CERN LHC exploit the substructure of jets to identify heavy resonances produced with high momenta that decay into multiple quarks and/or gluons. This paper presents a new technique for correcting the substructure of simulated large-radius jets from multiprong decays. The technique is based on reclustering the jet constituents into several subjets such that each subjet represents a single prong, and separately correcting the radiation pattern in the Lund jet plane of each subjet using a correction derived from data. The data presented here correspond to an integrated luminosity of 138 fb−1 collected by the CMS experiment between 2016–2018 at a center-of-mass energy of 13 TeV. The correction procedure improves the agreement between data and simulation for several different substructure observables of multiprong jets. This technique establishes, for the first time, a robust calibration for the substructure of jets with four or more prongs, enabling future measurements and searches for new phenomena containing these signatures. © The Author(s) 2025
Measurement of Light-By Scattering and the Breit-Wheeler Process, and Search for Axion-Like Particles in Ultraperipheral PbPb Collisions at √sNN=5.02 TeV
No full textMeasurements of light-by-light scattering (LbL, gamma gamma -> gamma gamma) and the Breit-Wheeler process (BW, gamma gamma -> e(+)e(-)) are reported in ultraperipheral PbPb collisions at a centre-of-mass energy per nucleon pair of 5.02 TeV. The data sample, corresponding to an integrated luminosity of 1.7 nb(-1), was collected by the CMS experiment at the CERN LHC in 2018. Events with an exclusively produced gamma gamma or e(+)e(-) pair with invariant masses m(gamma gamma,ee) > 5 GeV, along with other fiducial criteria, are selected. The measured BW fiducial production cross section, sigma(fid)(gamma gamma -> e(+)e(-)) = 263.5 +/- 1.8(stat) +/- 17.8(syst) mu b, as well as the differential distributions for various kinematic observables, are in agreement with leading-order quantum electrodynamics predictions complemented with final-state photon radiation. The measured differential BW cross sections allow discrimination between different theoretical descriptions of the photon flux of the lead ion. In the LbL final state, 26 exclusive diphoton candidate events are observed compared with 12.0 +/- 2.9 expected for the background. Combined with previous results, the observed significance of the LbL signal with respect to the background-only hypothesis is above five standard deviations. The measured fiducial LbL scattering cross section, sigma(fid)(gamma gamma -> gamma gamma) = 107 +/- 24(stat) +/- 13(syst) nb, is in agreement with next- to-leading-order predictions. Limits on the production of axion-like particles coupled to photons are set over the mass range 5-100 GeV, including the most stringent limits to date in the range of 5-10 GeV.FWF; FNRS; FWO (Belgium); CNPq; CAPES; FAPERJ; FAPERGS; FAPESP (Brazil); BNSF (Bulgaria); MoST; NSFC (China); CSF (Croatia); RIF (Cyprus); SENESCYT (Ecuador); ERC PRG [MoER TK202]; Academy of Finland; MEC; CEA; CNRS/IN2P3 (France); SRNSF; BMBF; DFG; HGF (Germany); NKFIH (Hungary); DAE; DST; IPM; SFI (Ireland); INFN (Italy); NRF (Republic of Korea); MES (Latvia); MOE; UM (Malaysia); BUAP; CONACYT; UASLP-FAI (Mexico); PAEC (Pakistan); FCT (Portugal); MESTD (Serbia); PCTI (Spain); MOSTR (Sri Lanka); Swiss Funding Agencies (Switzerland); NSTDA; TUBITAK; DOE; NSF; Marie-Curie programme; European Research Council; Horizon 2020 Grant [675440, 724704, 752730, 758316, 765710, 824093, 101115353, 101002207]; COST Action [CA16108]; Leventis Foundation; Alfred P.

The data were obtained with a variety of luminosities. The operating temperature of the strip tracker was changed several times during this period and results are shown as a function of temperature in several cases. Details of the system performance are presented, including occupancy, signal-to-noise ratio, Lorentz angle, and single-hit spatial resolution. Saturation effects in the APV25 readout chip preamplifier observed during early Run 2 are presented, showing the effect on various observables and the subsequent remedy. Studies of radiation effects on the strip tracker are presented both for the optical readout links and the silicon sensors. The observed effects are compared to simulation, where available, and they generally agree well with expectations.Marie-Curie program; European Research Council; Horizon 2020 Grant [675440, 724704, 752730, 758316, 765710, 824093, 101115353, 101002207]; COST Action [CA16108]; Leventis Foundation; Alfred P.
