(Türkiye Klinikleri Yayınevi, 2019) Kayabaşı, Serkan; Gül, Fatih
To investigate the possible risk factors that may lead to hearing loss in newborns who failed the hearing screening tests. Material and Methods: In this retrospective study,546 newborns who failed the evoked otoacoustic emission (TEOAE) test or who underwent screening auditory evoked brainstem response (ABR) due to detected risk factors were included between2010 and 2018. The risk factors of 78 patients who failed the screening ABR test were documented.A total of 468 newborns who passed ABR screening test were evaluated as control group. The datawere compared statistically. Results: In the comparison of groups who failed and passed the ABRscreening test, the mean birth time was found to be significantly earlier (38.1±2.6 and 39.25±1.4weeks, respectively) (p=0.049), and the mean birth weight was found to be significantly lower (3001±628.2 and 3334.82 ±418 g, respectively) (p=0.032) in the failed group. The incidence of neonataljaundice and jaundice requiring phototherapy was higher in patients who failed the screening ABRtest, and this difference was statistically significant (p=0.043 and p=0.028, respectively). The newborns receiving intensive care treatment were also found to be statistically higher (p=0.028). Conclusion: The highest risk group for sensorineural hearing loss in newborns may be considered as theones with low birth weight, early birth time and receiving intensive care treatment.

Our aim is to understand the mood states of the patients suffering from sudden hearing loss in terms of anxiety, stress and depression. Its role in etiology and its effect on prognosis was also investigated.Methods: The study included 100 patients (67 males, 33 females; mean age 46.5 years) who were diagnosed with sudden sensorineural hearing loss (SSHL). The DASS-42 questionnaire, which measures depression, anxiety, and stress, was filled out before the treatment of SSHL. Audiometric tests were performed to determine the pure tone average on days 1,3 and 7.Results: There was no difference between males and females according to DASS-42 mean depression, anxiety and stress scores (p = 0.785, p = 0.832, p = 0.712, respectively). While there was no statistically significant difference between the presence and absence of tinnitus in terms of depression and stress scores, a statistically significant difference was observed in terms of mean anxiety scores (p = 0.817, p = 0.134, p = 0.032, respectively). There was no statistically significant difference in mean depression scores between the groups with and without recovery, while the mean scores of anxiety and stress were statistically significant (p = 0.427, p = 0.012, p = 0.036, respectively).Conclusion: Anxiety and stress may be an etiologic factor and affect prognosis in SSHL.

Prick testpositivity and multiple allergen positivity rates were not observed to be significantly different between children and adults (p> 0.05).Conclusion: Allergic rhinitis was found to be the most common prick test indication. Patient groups with the highest prick test positivitywere angioneurotic edema and allergic rhinitis. Tree and shrub pollens were the most common allergens.
The comparison of readability between information texts from web sites of private clinics and private hospitals
(İnönü University, 2019) Kuzucu, İhsan
Rhinoplasty is a surgery which can be done in state hospitals, private hospitals and private clinics. Patients gen-erally go tothe most suitable clinic whereas most surgeons prefer to perform surgery in private clinics. Thus, patients often confuse where toattend. Social media plays a crucial role for patients to decide where and who to choose. We compared readability of the informationtext from internet pages of private clinics and private hos-pitals from both plastic surgeons and otorhinolaryngologists.Material and Methods: The word “Rhinoplasty” was searched through internet and first 30 web sites were taken into account. First100 words from information texts about rhinoplasty from both private clinic and hospital web sites were copied and studied using aprogram called LIDA. Gunnig-Fog index, Flesch-Kincaid and Atesman values were noted and evaluated.Results: The readability of both private hospitals and private clinics were found to be hard. Flesch-Kincaid values showed thatinformation texts from private clinics in web sites (23.24 ± 3.45) were significantly different (p=0,035) than private hospitals (25,19± 3,5). As believed to be more specific to Turkish, Atesman values in private clinics (48,58 ± 16,71) were found to be more readablethan private hospitals (38.81 ± 18.06) (p=0,034).Conclusion: Comparison of information texts between private clinics and private hospitals of plastic surgeons and otorhinolaryngologists showed that Atesman values, which are believed to be more specific to Turkish, and Flesch-Kincaid values weresignificantly high in private clinics suggesting it is easier to understand. To sum it up, infor-mation texts guide patients to privatecritics.

(İstanbul Üniversitesi, 2023) Sungur, İbrahim; Encü, Kadri; Aydın, Mahmud; Sürücü, Serkan; Çapkın, Sercan
Objective: Posterior malleolar fractures (PMF) are common among ankle fractures and their proper management is crucial to maintaining ankle stability. The purpose of this study was to compare the clinical and radiological effects of screw versus support plate fixation in the surgical treatment of PMF. Material and Methods: Between December 2016 and February 2018, 82 patients who underwent surgical treatment for PMF were analyzed retrospectively. Patients were divided into two groups based on the type of fixation material used: screws and buttress plates. Using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, range of motion measurements, and radiographic evaluations, clinical evaluations were conducted. Results: A total of 60 patients were included in the study, 33 of whom were treated with plate osteosynthesis and 27 with screw osteosynthesis. The demographic and clinical characteristics were similar between the groups. The AOFAS scores, range of motion measurements, and complication rates were comparable between the screw and plate fixation groups. The radiological evaluation showed no significant difference in posttraumatic arthritis levels between the two groups. Conclusion: The screw fixation alone provides similar clinical andmradiological results compared to buttress plate fixation in the surgicaln treatment of PMF. These results are in advance of the growing evidence supporting screw-only osteosynthesis for Haraguchi type 1 and 2 posterior malleolus fractures.
Carvacrol Ameliorates Cisplatin-Induced Cardiotoxicity By Regulating Notch/Hes1 Signaling Pathway, Oxidative Stress and Cell Death In Rat Cardiac Tissue
(Bingöl Üniversitesi Fen Bilimleri Enstitüsü, 2024) Akaras, Nurhan; Kandemir, Özge; Şimşek, Hasan
Cisplatin is one of the most active cytotoxic agents used mainly in the treatment of solid tumors. High doses and long-term use of Cisplatin are known to cause cardiotoxicity. In recent years, the antiapoptotic and antioxidant effects of Carvacrol in cardiovascular diseases have attracted attention. In this study, the effects of Carvacrol on Cisplatin-induced cardiotoxicity in a rat model were investigated using biochemical and histological methods. Twenty-eight rats were divided into 4 groups: 1. Control group, 2. Carvacrol group, 3. Cisplatin group, 4. Cisplatin + Carvacrol group. The expression of antioxidant enzymes, proinflammatory cytokines, apoptotic, and autophagic proteins was examined in heart tissue obtained from rats sacrificed after the last drug administration. Additionally, heart tissue was evaluated histopathologically. Cisplatin has been observed to cause oxidative stress and inflammatory damage in animal heart tissue. Carvacrol administration significantly increased antioxidant enzyme (superoxide dismutase and glutathione peroxidase) activities while suppressing inflammatory markers (NF-κB, TNF-α, IL-1β). Additionally, Cisplatin induced apoptotic (caspase-3, Bax, Bcl-2) and autophagic (Beclin-1, LC3A, LC3B) markers. It has been determined that carvacrol can protect heart tissues from the destructive effects of cisplatin by exerting anti-apoptotic and anti-autophagic effects. The expression levels of Notch1 and Hes1, which were decreased by cisplatin administration, were upregulated after administration of Carvacrol. H&E staining results showed that Carvacrol preserved myocardial tissue integrity. In conclusion, Carvacrol showed a cardioprotective effect against cisplatin-induced cardiotoxicity.
Protective Role of Carvacrol Against Diclofenac-Induced Cardiotoxicity: Effects on Oxidative Stress, Apoptosis, Inflammation, ER Stress and Autophagy
(Springer Nature, 2025) Gül, Murat; Kandemir, Özge; Akaras, Nurhan; Şimsek, Hasan; Çağlayan, Cüneyt
Diclofenac (Diclo) is a widely used nonsteroidal anti-inflammatory drug (NSAID) for managing pain, inflammation, and joint disorders. However, studies have shown that diclofenac may induce cardiotoxicity via oxidative stress, inflammation, apoptosis, ER stress, and autophagy. Carvacrol (CRV), a natural monoterpenoid phenol, exhibits antioxidant, anti-inflammatory, and cytoprotective properties. This study aimed to evaluate the protective effects of carvacrol against diclofenac-induced cardiotoxicity by assessing relevant molecular and histological markers.MethodsIn the study, 35 Wistar rats were divided into 5 groups; Control, CRV, Diclo, Diclo + CRV25, and Diclo + CRV50. Diclo was administered intraperitoneally at a dose of 50 mg/kg. CRV (25 mg/kg and 50 mg/kg) was administered via oral gavage. Biochemical, molecular, and histological methods were used to investigate indicators of oxidative stress, inflammation, apoptosis, and ER stress damage in heart tissue.ResultsCRV treatment attenuated oxidative stress damage by reversing Diclo-induced changes: it significantly increased the levels of antioxidant markers (SOD, CAT, GPx, GSH) and decreased MDA levels, a marker of lipid peroxidation. CRV also reduced inflammatory mediators such as NF-kappa B and other pro-inflammatory cytokines. Furthermore, CRV downregulated apoptotic markers Bax and Caspase-3 while upregulating anti-apoptotic markers AKT-2 and Bcl-2. ER stress-associated proteins (ATF-6, PERK, IRE1, GRP-78) elevated by Diclo were also reduced by CRV. In addition, CRV alleviated structural and functional cardiac damage induced by Diclo.ConclusionOverall, CRV may be an effective treatment option for cardiac tissue damage caused by Diclo toxicity and may reduce the level of damage.

(Aksaray Üniversitesi, 2025) Babayiğit, Muammer; Geyik, Serdar; Bayburtluoğlu, Veysel
following prostate surgeries. The aim of this study is to evaluate the outcomes of transurethral deep lateral incision without intralesional agents in the management of recurrent BNC and to compare the results with existing literature. Material and Method: A retrospective analysis of 12 patients who underwent transurethral deep lateral incision for recurrent BNC between January 2023 and June 2024 was performed. Data collected included demographic characteristics, surgical details, and postoperative outcomes. Success was defined as the absence of dilation requirements and a lack of obstructive uroflowmetric patterns within 6 months. Complications were classified according to the modified Clavien-Dindo system. Results: The mean age of the patients was 68.25 years. Etiologies included radical prostatectomy (5 patients), transurethral resection of the prostate (5 patients), and combined radical prostatectomy with radiotherapy (2 patients). The mean operative duration was 32.67 minutes, and the overall success rate was 83.3%. Two patients (16.6%) experienced recurrence requiring additional intervention. Postoperative incontinence was observed in 16.6% of cases and was managed conservatively. No intralesional agents were used, and the procedure achieved comparable success rates to more complex techniques with fewer associated complications. Conclusion: Transurethral deep lateral incision is an effective and minimally invasive technique for managing recurrent BNC, offering high success rates without the need for intralesional agents. This approach can be considered a primary treatment option before resorting to more invasive surgical methods.
Potent Ameliorative Effects of Rosmarinic Acid on Tramadol-Induced Neurotoxicity in the Brain and Hippocampus; by Suppressing Oxidative stress, Apoptosis, ER stress, and Regulating Cognitive Functions
(Springer, 2025) Karaca, Onur; Şimşek, Hasan; Akaras, Nurhan; Gür, Cihan; İleritürk, Mustafa; Kandemir, Özge; Küçükler, Sefa; Karaca, Şeyda Öte; Kandemir, Fatih Mehmet
Tramadol (TRM) is a synthetic opioid analgesic that acts on the central nervous system and is used to treat moderate or severe pain. However, the incidence of its abuse is increasing. Rosmarinic acid (RA) is a natural flavonoid known for its antioxidant, anti-inflammatory, and neuroprotective properties. In this study, we determined the ameliorative effects of RA against TRM-induced neurotoxicity. Thirty five rats were divided into 5 groups; control, RA, TRM, TRM + RA25 and TRM + RA50. TRM 50 mg/kg was administered intraperitoneally, and RA 25 and 50 mg/kg doses were administered by oral gavage for 14 days. Water Maze Test (WMT) was performed to assess cognitive function. Oxidative stress, inflammation, endoplasmic reticulum (ER) stress, apoptosis damage pathways, glial fibrillary acidic protein (GFAP), and brain-derived neurotrophic factor (BDNF) activities were determined in brain and hippocampus tissues. The structural and functional integrity of the tissues were also analyzed. RA decreased TRM-induced increased oxidative stress, inflammation, ER stress, and apoptotic damage levels. In addition, it improved neuronal survival and activity by bringing BDNF and GFAP activities closer to normal in brain tissue. RA restored the structural properties of brain and hippocampus tissues disrupted by tramadol. These findings were also demonstrated using WMT, which improved the arrival time to the quadrant in which the platform was located and the time spent in the quadrant. RA reduces TRM-induced neurotoxicity by reducing inflammation, oxidative stress, ER stress, and apoptotic damage and increases neuronal survival and activity.
Hesperidin ameliorates vancomycin-induced kidney injury via multipathway modulation: Nrf-2/HO-1, Caspase-3/Bax/Bcl-2, ATF-4, KIM-1 and improved renal tissue function
(Elsevier Inc., 2025) Gencer, Selman; Şimşek, Hasan; Akaras, Nurhan; Gür, Cihan; İleritürk, Mustafa; Kandemir, Özge; Küçükler, Sefa; Kankılıç, Nazım Abdülkadir; Kandemir, Fatih Mehmet
Vancomycin (VCM) is a therapeutic agent used to treat drug-resistant gram-positive bacteria. However, its high-dose use is associated with nephrotoxicity, limiting its clinical application. Hesperidin (HES), a flavonoid naturally found in citrus fruits, exhibits various biological and pharmacological activities, including anti-inflammatory, antioxidant, and anticancer effects. While HES has been shown to exert protective effects in several organ systems, its potential role in preventing VCM-induced nephrotoxicity remains unclear. This study investigates whether HES can mitigate VCM-induced renal damage through its antioxidant and anti-inflammatory properties. VCM was administered intraperitoneally at a dose of 200 mg/kg for seven days. HES (100 mg/kg and 200 mg/kg) was administered orally for seven days. Biochemical, and molecular methods were used to investigate indicators of oxidative stress, ER stress damage, apoptotic and autophagic death in kidney tissue. Additionally, histological methods were used to determine the structural and functional characteristics of kidney tissue. HES treatment alleviated VCM-induced oxidative stress by increasing antioxidants (SOD, CAT, GPx, GSH) and reducing increased MDA levels, a marker of lipid peroxidation. In addition, HES increased antioxidant activity by activating the Nrf2 signaling pathway. VCM-induced increases in apoptotic Bax, Caspase-3, and P53 were reduced by HES, while the decreased level of antiapoptotic Bcl-2 was increased. HES reduced VCM-induced ER stress damage by reducing the levels of ATF-4, ATF-6, eIF2-α, and CHOP. HES treatment attempted to preserve kidney function and structural integrity. Overall, HES was effective in reducing VCM-induced nephrotoxicity damage and may be an effective treatment option.
Protective Effects of Baicalein and Bergenin Against Gentamicin-Induced Hepatic and Renal Injuries in Rats: An Immunohistochemical and Biochemical Study
(John Wiley and Sons Inc, 2025) Ekinci Akdemir, Fazile Nur; Yıldırım, Serkan; Kandemir, Fatih Mehmet; Küçükler, Sefa; Eraslan, Ersen; Güler, Mustafa Can
Drug-induced organ toxicity is a significant health concern, with gentamicin known for its effective antibacterial properties but also severe side effects, particularly cytotoxicity in liver and kidney tissues. This current study observed the preventive role of baicalein and bergenin against hepatic and renal injuries caused by gentamicin in rats. Methods: Thirty-two male Sprague Dawley rats were divided into four groups, namely, control, gentamicin (gentamicin 80 mg/kg/day), baicalein (gentamicin 80 mg/kg/day + baicalein 100 mg/kg/day) and bergenin (gentamicin 80 mg/kg/day + bergenin 100 mg/kg/day). Hepatotoxicity and nephrotoxicity were induced by giving gentamicin (80 mg/kg/day). We evaluated the biochemical markers, including alkaline phosphatase (ALP), urea, alanine transaminase (ALT), creatinine and aspartate transaminase (AST) levels, antioxidant enzymes, oxidative stress parameters and histopathological and immunohistochemical changes. Results: Gentamicin increased oxidative stress parameters and decreased antioxidant activity. The treatment with baicalein and bergenin significantly restored these markers. Conclusions: Baicalein and bergenin significantly mitigated gentamicin-induced hepatic and renal toxicity by restoring biochemical markers, reducing oxidative stress and enhancing antioxidant enzyme activity. Histopathological and immunohistochemical analyses confirmed the protective effects of both compounds against organ damage. No statistically significant differences were observed between the two drugs for these parameters. These results suggest their potential as therapeutic agents to prevent gentamicin-induced organ toxicity.

(John Wiley and Sons Inc, 2025) Ensari, Esra; Akyol Önder, Esra Nagehan; Ertan, Pelin
This study evaluated the reliability, quality, and readability of ChatGPT (OpenAI, San Francisco, CA), Gemini (Google, Mountain View, CA), and Copilot (Microsoft Corp., Washington, DC) which are among the most widely used large language models (LLMs) today in answering frequently asked questions (FAQs) related to pediatric dialysis. Methods: A total of 45 FAQs were entered into LLM. The Modified DISCERN (mDISCERN) scale assessed reliability; the Global Quality Score (GQS) evaluated quality; and readability was assessed using five metrics: Coleman-Liau Index (CLI), Simple Measure of Gobbledygook (SMOG), Gunning Fog Index (GFI), Flesch Reading Ease (FRE) and Flesch–Kincaid Grade Level (FKGL). Questions were directed to the chat robots twice, on January 25, 2025, and February 1, 2025. Results: All three chatbots displayed high reliability, achieving median mDISCERN scores of 5. Quality scores on the GQS were similarly high, with median scores of 5 across platforms; however, Gemini exhibited greater variability (range 1–5) compared to ChatGPT-4o and Copilot (ranges 3–5). Readability scores revealed that chatbot responses were written at an advanced level. Conclusion: This study found that LLMs responses to dialysis FAQs were reliable and high quality, but difficult to read; improving readability through expert-reviewed content could increase their impact on public health.

(Multidisciplinary Digital Publishing Institute (MDPI), 2025) Erzincan, Rahime; Çağlayan, Cüneyt; Kandemir, Fatih Mehmet; İzol, Ebubekir; Gür, Cihan; İleritürk, Mustafa
Vincristine (VCR) is a chemotherapeutic agent classified as a vinca alkaloid. Royal jelly (RJ) is a significant bee product produced by worker bees, characterized by its high protein content. This study aims to investigate the protective effects of RJ against VCR-induced liver damage. VCR was intraperitoneally administered at a dose of 0.1 mg/kg body weight (b.w.) and RJ was orally administered at doses of 150 and 300 mg/kg b.w. Both treatments were applied to the rats on days 1–6 and 9–14. The composition of RJ was analyzed using LC-MS/MS, revealing the presence of 15 different phytochemical compounds with strong antioxidant properties. Serum samples obtained from the rats were analyzed for ALT, ALP, and AST levels. While these enzyme levels were significantly elevated in the VCR group, a notable reduction was observed following RJ administration. Additionally, SOD, CAT, GPx, and GSH antioxidant parameters, along with MDA levels, were evaluated in liver tissue samples. The results indicated a decrease in SOD, CAT, GPx, and GSH activities/levels and an increase in MDA levels in the VCR group. Furthermore, ELISA was used to assess JAK2, STAT3, and mTOR/PI3K/AKT signaling pathways. VCR administration led to a decrease in mTOR/PI3K/AKT levels and an increase in JAK2 and STAT3 levels. In addition, the mRNA transcription levels of inflammation (NF-κB, TNF-α, and IL-1β), endoplasmic reticulum (ER) stress (IRE-1, GRP78, PERK, and ATF-6), and autophagy markers (LC3A and LC3B) were examined. A significant increase in inflammation, ER stress, and autophagy-related markers was observed in the VCR-treated group. Lastly, the protein expression levels of Bax, Bcl-2, Caspase-3, and NF-κB were evaluated. VCR treatment increased Bax, Caspase 3, and NF-κB levels, whereas Bcl-2 levels were decreased. However, following RJ administration, all these parameters were reversed, demonstrating significant improvements. In conclusion, these findings suggest that RJ may exert a protective effect against VCR-induced liver damage.

Diclofenac (Diclo) is a therapeutic agent used in the treatment of pain and inflammatory diseases, but it is also toxic to the human body. Morin is a flavonoid found naturally in plants and has many biological and pharmacological activities, including anti-inflammatory, anti-oxidant, and anticancer activities. This study aimed to investigate the efficacy of Morin in Diclo-induced testicular toxicity. Materials and Methods: Morin (50 mg/kg and 100 mg/kg) was administered orally for five days, while Diclo was administered intraperitoneally at 50 mg/kg on days 4 and 5. Biochemical, molecular, and histological methods were used to investigate oxidative stress, inflammation, apoptosis, and endoplasmic reticulum (ER) stress damage indicators in testicular tissue. Results: Morin treatment attenuated Diclo-induced oxidative stress damage by increasing anti-oxidant levels (SOD, CAT, GPx, GSH, Nrf-2, HO-1, and NQO1) and decreasing MDA levels, an indicator of lipid peroxidation. Morin reduced levels of the inflammatory mediators NF-κB protein. Increases in apoptotic Bax and Caspase-3 by Diclo were reduced by Morin, while decreased antiapoptotic Bcl-2 level was increased. Morin reduced Diclo-induced ER stress injury by decreasing ATF-6, PERK, IRE1, GRP-78, and CHOP levels. Also, Diclo decreased COX-2 levels. Conclusion: Overall, Morin may be an effective treatment of choice for testicular tissue damage associated with Diclo toxicity and may reduce the level of damage.

Acrylamide (ACR) is a toxic chemical with a high carcinogenic risk that is released as a result of heating or processing foods at high temperatures. Chrysin (CHR) is a flavonoid that is naturally found in foods such as honey and passionflower and stands out with its antioxidant, anticancer, and anti-inflammatory properties. This study aims to determine the protective effects of CHR in ACR-induced hepatotoxicity. ACR was administered orally at a dose of 38.27 mg/kg; CHR (25 or 50 mg/kg) was administered orally for ten days. Biochemical and molecular methods were used to investigate oxidative stress, inflammation, and apoptotic markers in liver tissue. Additionally, histological methods were used to determine the liver tissue's structural and functional characteristics and autophagy. CHR treatment alleviated ACR-induced oxidative stress by increasing antioxidants (SOD, CAT, GPx, GSH) and reducing increased oxidant MDA. CHR reduced inflammatory activity by inactivating NF-κB and pro-inflammatory cytokines. ACR-induced increases in apoptotic Casp-3, Casp-6, Casp-9, and Bax were reduced by CHR, while the decreased level of antiapoptotic Bcl-2 was increased. It was also determined immunohistochemically that CHR inhibited autophagic Beclin-1 activity. CHR was effective in reducing ACR-induced hepatotoxicity damage and may be an effective treatment option.

Aim: Potassium bromate (KBrO3) is a colorless, odorless substance used as a food additive. It causes multiple organ damage and neurotoxicity. Morin is a flavonoid from the Moraceae family known to have anti-inflammatory, antioxidant, antiapoptotic, antiautophagic, and neuroprotective properties. Therefore, this study aimed to investigate the effects of Morin against KBrO3-induced brain damage. Methods: 62 mg/kg KBrO3 and 50–100 mg/kg Morin were administered to 35 male rats by oral gavage daily for 14 days. Various analyses were performed using molecular, biochemical, and histological methods. Results: The analyses results showed that KBrO3 application decreased antioxidant markers and raised lipid peroxidation in the brain tissue. The KBrO3 application triggered apoptosis, endoplasmic reticulum stress, and inflammation. Morin treatment increased enzymatic and nonenzymatic antioxidant levels and decreased lipid peroxidation. In addition, Morin alleviated KBrO3-induced apoptosis, endoplasmic reticulum stress, and inflammation in the brain tissue. The histopathological analysis revealed an increase in degenerative changes, as well as pyknotic changes and vacuolization in cells, in neurons in the KBrO3 group. Increased hyperemia and congestion were detected in the meninges and vessels in the cerebral cortex. Conclusion: KBrO3 application caused toxicity in the brain tissue and impaired tissue integrity, whereas Morin treatment alleviated KBrO3-induced toxicity.
