Objective: This study aimed to explore the holistic relationship between personality types, coping attitudes, physical functioning, and cognitive levels in individuals diagnosed with stroke. Material and Methods: The research employed a single-group design and included 25 stroke patients. The participants, comprising 7 females and 12 males with a mean age of 54.211±8.979 years, underwent a comprehensive assessment. Physical function was assessed using the Berg Balance Scale and Timed Up and Go Tests, and cognitive levels were measured with the Montreal Cognitive Assessment Scale, coping strategies were evaluated through the COPE-R Coping Attitudes Evaluation Scale, and personality types were determined using the Enneagram Scale. Results: A significant correlation was identified between the Montreal Cognitive Assessment, Timed Up and Go, and Berg Balance Scales (p<0.05). However, no significant correlation was observed between COPE-R Coping Attitudes and Enneagram scales (p=0.503). Conclusion: This study underscores the interplay between cognitive and physical functioning in stroke survivors, highlighting the potential impact of cognitive levels on physical capabilities. Surprisingly, coping attitudes and personality types did not significantly influence cognitive or physical function.

Objective: This study aims to identify the intellectual structure, prominent themes, and diseases associated with geriatric emergency care. Additionally, it seeks to establish research questions for future studies. Material and Methods: Co-citation and co-occurrence analyses were conducted for bibliometric evaluations. The Web of Science database was utilized. Diseases mentioned in 939 articles were identified through thematic coding analysis of abstracts and titles. Finally, questions for the future agenda were prepared. Bibliometric analyses were carried out using R-based Bibliometrix software. Results: Co-citation analysis revealed two main themes: "Adverse Outcomes in Elderly Post-Emergency Service, Delirium Identification, and Multidisciplinary Interventions" and "Diagnosis and Management of Cognitive Dysfunction in Elderly Emergency Department Patients." Co-occurrence analyses indicate that the literature clusters around key themes such as "risk and prevalence," "management and epidemiology," "physical performance," "elderly care and outcomes," "elderly and community," "survival and prognosis," and "stroke and related diseases." According to the list of diseases, the ten most frequently studied diseases in geriatric emergency articles are, in order, Cancer, Stroke, Dementia, Depression, Delirium, Alzheimer's, Carcinoma, Metabolic Syndrome, Type 2 Diabetes, and Heart Failure. Conclusion: Adopting a comprehensive approach is essential for improving older adults' quality of life and independenceHealthcare providers and decision-makers should take these findings into consideration, as they make significant contributions to the health and independence of the elderly population. Furthermore, questions for future research agendas have been formulated.

Objective: This study aims to investigate the impact of parental anxiety and a history of epilepsy on children's dental anxiety. Materials and Methods: The study involved 84 children aged 4 to 12 who visited the Pedodontics Department at Necmettin Erbakan University. The subjects were divided into two groups: children with no history of epilepsy (Group 1, n = 44) and children with a history of epilepsy (Group 2, n = 40). Before receiving dental treatment, each child was asked to independently complete the Children's Dental Anxiety Screening Scale (CFSS-DS) questionnaire. Parental dental anxiety was assessed using the Turkish version of the Modified Dental Anxiety Scale (MDAS), which categorizes dental anxiety into five levels. Results: There was no statistically significant difference in CFSS-DS total scores between Group 1 and Group 2 (p = 0.103). Pearson Correlation analysis revealed a statistically significant weak positive association between parental anxiety and children's dental anxiety (p = 0.008). Conclusion: This study found a significant and linear correlation between children's dental anxiety and their parents' dental anxiety. However, it could not establish a direct link between a child's medical history of epilepsy and their anxiety.
目的:探讨父母焦虑和癫痫史对儿童牙科焦虑的影响。材料和方法:该研究涉及84名4至12岁的儿童,他们在Necmettin Erbakan大学的儿科学部门就诊。研究对象分为两组:无癫痫史儿童(1组,n = 44)和有癫痫史儿童(2组,n = 40)。在接受牙科治疗前,每个儿童被要求独立完成儿童牙科焦虑筛查量表(CFSS-DS)问卷。使用土耳其版的改良牙科焦虑量表(MDAS)评估父母的牙科焦虑,该量表将牙科焦虑分为五个级别。结果:两组患者CFSS-DS总分比较,差异无统计学意义(p = 0.103)。Pearson相关分析显示,父母焦虑与儿童牙科焦虑呈显著的弱正相关(p = 0.008)。结论:本研究发现儿童的牙科焦虑与父母的牙科焦虑有显著的线性相关。然而,它不能在儿童的癫痫病史和他们的焦虑之间建立直接的联系。

Objective: The objective of this work is to investigate the histological and biochemical consequences of administering Dexmedetomidine (DEX), an alpha-2 adrenergic receptor agonist with notable sedative qualities as well as antioxidant and anti-inflammatory characteristics, in the context of Carbon tetrachloride (CCl4)-induced kidney injury. Materials and Methods: The experimental design involved the random allocation of 30 Sprague-Dawley rats into three distinct groups. The experimental group designated as Group 1 received a single intraperitoneal administration of 1ml of saline solution containing 0.09% NaCl. Group 2 received an intraperitoneal injection of carbon tetrachloride (CCl4) at a dosage of 2 milliliters per kilogram. Group 3, referred to as the CCl4+Dexmedetomidine group, received a solitary intraperitoneal (i.p.) dosage of 100 µg/kg dexmedetomidine one hour before the intraperitoneal administration of 2mL/kg CCl4. Results: Extensive necrosis and debris accumulation were observed in the tubules, particularly in the proximal tubules, within the CCl4-applied group. An elevation in malondialdehyde (MDA) concentrations and terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL) positivity, along with a reduction in glutathione (GSH) levels, was found in the renal tissues of the CCl4 experimental group as compared to the control group. In contrast, the CCl4+DEX group exhibited a reduction in the quantity of necrotic tubular cells, levels of MDA, and TUNEL positive. Additionally, there was an elevation in GSH levels compared to the group treated with CCl4 alone. Conclusions: The administration of dexmedetomidine has been observed to potentially provide a protective effect against renal damage induced by CCl4. This phenomenon could potentially be linked to the modulation of tissue oxidative stress markers and the attenuation of apoptotic rate. The findings of our investigation provide evidence in favour of the utilization of dexmedetomidine as a promising therapeutic drug for mitigating renal injury.
目的:本研究旨在探讨右美托咪定(DEX)在四氯化碳(CCl4)所致肾损伤中的组织学和生化影响。右美托咪定是一种具有显著镇静、抗氧化和抗炎作用的α -2肾上腺素受体激动剂。材料与方法:实验设计30只Sprague-Dawley大鼠随机分为3组。实验组为第1组,单次腹腔注射含0.09% NaCl的生理盐水1ml。第二组腹腔注射四氯化碳(CCl4),剂量为每公斤2毫升。第3组,CCl4+右美托咪定组,在CCl4 2mL/kg腹腔注射前1小时单独腹腔给药100µg/kg右美托咪定。结果:应用ccl4组,小管,尤其是近端小管出现广泛坏死和碎片堆积。与对照组相比,CCl4实验组肾脏组织中丙二醛(MDA)浓度升高,末端脱氧核苷酸转移酶dUTP缺口末端标记(TUNEL)阳性,谷胱甘肽(GSH)水平降低。相比之下,CCl4+DEX组显示坏死小管细胞数量减少,MDA水平降低,TUNEL阳性。此外,与单独使用CCl4治疗组相比,GSH水平升高。结论:右美托咪定已被观察到对CCl4引起的肾损害有潜在的保护作用。这种现象可能与组织氧化应激标志物的调节和细胞凋亡率的衰减有关。我们的研究结果为右美托咪定作为减轻肾损伤的治疗药物提供了有利的证据。

Objective: While Multiple Life-threatening Conditions (MLCs) admitted to the Pediatric Intensive Care Unit represent a substantial healthcare burden, the risk factors, epidemiological data, and clinical manifestations of these cases have yet to be systematically and comprehensively documented. Material and Methods: This study was conducted in the Pediatric Intensive Care Unit at Bursa Yuksek Ihtisas Training and Research Hospital, Bursa, Turkey, between January 1, 2017, and January 1, 2022. The study included 31 males (35.4%) and 17 females (64.6%) with an average age of 4.7 ± 4.1 years. MLCs were classified into nine groups, including Foreign Body Aspiration (FBA), Blunt Trauma (BT), Asphyxia (ASP), Firearm Injury (FI), Sharp and Penetrating Object Injury (SPOI), Electric Injury (EI), Sports-Related Injury (SRI), Animal Bite Injury (ABI), and Home Accident (HA). Results: Foreign Body Aspiration (FBA) was the most prevalent type of MLC in this study (29.1%). The average hospital stay for FBA cases in the general ward was 3 days (range: 1-11 days), and in the Pediatric Intensive Care Unit was 2 days (range: 1-8 days). Blunt Trauma (BT) cases had an average hospital stay of 4 days (range: 1-12 days) in the general ward and 3 days (range: 1-10 days) in the Pediatric Intensive Care Unit. Surgical intervention was required for 29.1% of patients (n=14). The mean cost of treating a case in our study was calculated to be 5744 ₺ (approximately US$308.57). The majority of MLCs were attributed to FBA (n=14, 43%), followed by BT (n=9, 18%), and ASP (n=8, 16%). Conclusion: The predominance of Multiple Life-threatening Conditions (MLCs) in the Pediatric Intensive Care Unit, with Foreign Body Aspiration (FBA) being the most common cause, underscores the need for heightened awareness and prevention efforts. Understanding the risk factors, clinical presentations, and healthcare costs associated with these cases is essential for healthcare professionals and policymakers in their pursuit of reducing the incidence of MLCs.
目的:虽然儿科重症监护病房收治的多种危及生命的疾病(MLCs)是一个巨大的医疗负担,但这些病例的危险因素、流行病学数据和临床表现尚未得到系统和全面的记录。材料和方法:本研究于2017年1月1日至2022年1月1日在土耳其Bursa Yuksek Ihtisas培训和研究医院的儿科重症监护室进行。男性31例(35.4%),女性17例(64.6%),平均年龄4.7±4.1岁。MLCs分为9组,分别为异物吸入(FBA)、钝性损伤(BT)、窒息(ASP)、火器伤(FI)、锐器穿透伤(SPOI)、电伤(EI)、运动相关伤(SRI)、动物咬伤(ABI)和家庭意外伤(HA)。结果:异物吸入(FBA)是本研究中最常见的MLC类型(29.1%)。FBA病例在普通病房的平均住院时间为3天(范围:1-11天),在儿科重症监护病房的平均住院时间为2天(范围:1-8天)。钝性创伤(BT)病例在普通病房的平均住院时间为4天(范围:1-12天),在儿科重症监护室的平均住院时间为3天(范围:1-10天)。29.1%的患者(n=14)需要手术干预。在我们的研究中,治疗一个病例的平均费用为5744元(约308.57美元)。大多数MLCs归因于FBA (n= 14,43%),其次是BT (n= 9,18%)和ASP (n= 8,16%)。结论:多种危及生命的疾病(MLCs)在儿科重症监护室占主导地位,其中异物吸入(FBA)是最常见的原因,强调了提高认识和预防工作的必要性。了解与这些病例相关的风险因素、临床表现和医疗费用对于医疗保健专业人员和政策制定者降低MLCs发病率至关重要。

Objective: The correlation between Body Mass Index (BMI) and vitamin D levels has garnered considerable attention in contemporary medical investigations. Vitamin D, an essential fat-soluble micronutrient, significantly influences bone health, immune system functionality, and various other physiological functions. The bioavailability of vitamin D may be affected by adiposity, which might result in possible deficits in persons with elevated body mass indices. The objective of this retrospective study conducted at a single center was to examine the potential relationship between BMI and diabetes mellitus (DM) with vitamin D serum levels in a cohort of 680 individuals, comprising 511 females and 169 males. Methods: The present study utilized a methodology in which medical records from a single facility were comprehensively reviewed to collect relevant information on BMI and blood 25-hydroxyvitamin D [25(OH)D] levels. The participants were classified into four distinct groups based on their BMI categories, which included normal weight, overweight, obese, and morbidly obese. Statistical methods were employed to investigate the relationship between BMI, diabetes mellitus (DM), age, and 25-hydroxyvitamin D (25(OH)D) levels. Furthermore, multivariate regression analysis was conducted to account for potential confounding variables such as age and gender. Results: The study included a sample of 680 individuals, comprising 511 women (75.1%) with an average age of 41 (±12) and 169 men (24.9%) with an average age of 38 (±13). Vitamin D levels in women were found to be 14±7 ng/mL, while in men, the levels measured at 16.6±7 ng/mL. The study identified a statistically significant difference in vitamin D levels between women and men (p<0.001). The study's findings indicate that there was no significant correlation between vitamin D levels and age among all individuals (p=0.258). However, a significant albeit weak correlation was observed between vitamin D levels and BMI (p=0.002, R2=0.0141). The vitamin D levels of the obese group were measured to be 14±7 ng/mL, while the non-obese group had levels of 16±7 ng/mL. Statistical analysis revealed that vitamin D levels in the obese group were significantly lower compared to the non-obese group (p=0.012). When comparing vitamin D levels between individuals with and without diabetes mellitus (DM), it was observed that the mean vitamin D level was 13.8±6.3 ng/mL in the non-DM group and 16.6±7.6 ng/mL in the DM group. Statistical analysis revealed that vitamin D levels were significantly higher in the DM group (p=0.012). Conclusion: Our study's findings suggest a potential connection between low vitamin D levels and obesity, while factors such as diabetes, age, and gender do not seem to significantly impact this association.
目的:身体质量指数(BMI)与维生素D水平的相关性在当代医学研究中引起了相当大的关注。维生素D是一种必需的脂溶性微量营养素,对骨骼健康、免疫系统功能和其他各种生理功能有重要影响。维生素D的生物利用度可能受到肥胖的影响,这可能导致体重指数升高的人缺乏维生素D。这项在单一中心进行的回顾性研究的目的是在680人的队列中检查BMI和糖尿病(DM)与维生素D血清水平之间的潜在关系,其中包括511名女性和169名男性。方法:本研究采用的方法是全面审查来自单一机构的医疗记录,以收集BMI和血液25-羟基维生素D [25(OH)D]水平的相关信息。参与者根据他们的身体质量指数类别被分为四组,包括正常体重、超重、肥胖和病态肥胖。采用统计学方法探讨BMI、糖尿病(DM)、年龄与25(OH)D水平的关系。此外,还进行了多变量回归分析,以解释年龄和性别等潜在的混杂变量。结果:本研究纳入680人样本,其中女性511人(75.1%),平均年龄41(±12)岁;男性169人(24.9%),平均年龄38(±13)岁。女性体内的维生素D含量为14±7纳克/毫升,而男性体内的维生素D含量为16.6±7纳克/毫升。研究发现,女性和男性在维生素D水平上存在统计学上的显著差异(p<0.001)。研究结果表明,在所有个体中,维生素D水平与年龄之间没有显著的相关性(p=0.258)。然而,维生素D水平与BMI之间存在显著的相关性(p=0.002, R2=0.0141)。肥胖组的维生素D水平为14±7 ng/mL,非肥胖组的维生素D水平为16±7 ng/mL。统计分析显示,肥胖组的维生素D水平明显低于非肥胖组(p=0.012)。在比较糖尿病和非糖尿病个体之间的维生素D水平时,发现非糖尿病组的平均维生素D水平为13.8±6.3 ng/mL,糖尿病组的平均维生素D水平为16.6±7.6 ng/mL。统计分析显示,糖尿病组维生素D水平显著高于糖尿病组(p=0.012)。结论:我们的研究结果表明,低维生素D水平和肥胖之间存在潜在的联系,而糖尿病、年龄和性别等因素似乎对这种联系没有显著影响。

Vitamin D, an essential fat-soluble micronutrient, significantly influences bone health, immune system functionality, and various other physiological functions. The bioavailability of vitamin D may be affected by adiposity, which might result in possible deficits in persons with elevated body mass indices. The objective of this retrospective study conducted at a single center was to examine the potential relationship between BMI and diabetes mellitus (DM) with vitamin D serum levels in a cohort of 680 individuals, comprising 511 females and 169 males. Methods: The present study utilized a methodology in which medical records from a single facility were comprehensively reviewed to collect relevant information on BMI and blood 25-hydroxyvitamin D [25(OH)D] levels. The participants were classified into four distinct groups based on their BMI categories, which included normal weight, overweight, obese, and morbidly obese. Statistical methods were employed to investigate the relationship between BMI, diabetes mellitus (DM), age, and 25-hydroxyvitamin D (25(OH)D) levels. Furthermore, multivariate regression analysis was conducted to account for potential confounding variables such as age and gender. Results: The study included a sample of 680 individuals, comprising 511 women (75.1%) with an average age of 41 (±12) and 169 men (24.9%) with an average age of 38 (±13). Vitamin D levels in women were found to be 14±7 ng/mL, while in men, the levels measured at 16.6±7 ng/mL. The study identified a statistically significant difference in vitamin D levels between women and men (p<0.001). The study's findings indicate that there was no significant correlation between vitamin D levels and age among all individuals (p=0.258). However, a significant albeit weak correlation was observed between vitamin D levels and BMI (p=0.002, R2=0.0141). The vitamin D levels of the obese group were measured to be 14±7 ng/mL, while the non-obese group had levels of 16±7 ng/mL. Statistical analysis revealed that vitamin D levels in the obese group were significantly lower compared to the non-obese group (p=0.012). When comparing vitamin D levels between individuals with and without diabetes mellitus (DM), it was observed that the mean vitamin D level was 13.8±6.3 ng/mL in the non-DM group and 16.6±7.6 ng/mL in the DM group. Statistical analysis revealed that vitamin D levels were significantly higher in the DM group (p=0.012). Conclusion: Our study's findings suggest a potential connection between low vitamin D levels and obesity, while factors such as diabetes, age, and gender do not seem to significantly impact this association.","PeriodicalId":18486,"journal":{"name":"Medical Science and Discovery","volume":"15 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135511666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: Currently, mononuclear cell (MNC) isolation is performed using density gradient methods, which are laborious and time-consuming, requiring a minimum of 10 ml of buffy coat or blood. This method is inadequate for isolating MNCs from small volumes, such as 100 µl. Therefore, we aimed to develop a straightforward, rapid, and cost-effective method for isolating MNCs from minute volumes of blood and buffy coat. Material and Methods: We utilized the MNC isolator to isolate MNCs from microvolumes, such as 100 µl and 500 µl of blood and buffy coat, by simple mixing and centrifugation. The isolated cells were cultured, and ligand-specific magnetic beads were employed to isolate CD4 and CD45 specific cells from the cultured cells. Results: In 15 experiments, the MNC isolator successfully isolated MNCs from small volumes of blood and buffy coat. The cell cultures were established and maintained for up to 3 years without contamination, with the cells remaining healthy. Successful isolations of CD4 and CD45 cells using magnetic beads were achieved, and the cells were successfully frozen and thawed. Conclusion: In this study, we have introduced a simple, cost-effective, and robust method for isolating MNCs from small volumes of buffy coat and blood, suitable for immunological applications and magnetic bead cell isolation. This method is user-friendly and can be adopted in cell culture laboratories worldwide, potentially opening new avenues for the development of novel antibodies, isolation of various cell populations using magnetic beads, and obtaining a large number of T-cells for immunotherapy development, such as CAR T-cell therapies. Keywords: mononuclear cell isolation, buffy coat, blood, CD4 positive cells, magnetic beads
目的:目前,单个核细胞(MNC)的分离是使用密度梯度方法进行的,这种方法既费力又耗时,需要至少10ml的灰白色被毛或血液。这种方法不适用于从小体积(如100µl)中分离MNCs。因此,我们的目标是开发一种简单、快速、经济有效的方法,从微量血液和灰褐色被毛中分离MNCs。材料和方法:我们利用MNC分离器从100µl和500µl的血液和灰白色被毛中分离出MNCs,通过简单的混合和离心。将分离的细胞进行培养,利用配体特异性磁珠从培养细胞中分离CD4和CD45特异性细胞。结果:在15次实验中,MNC分离器成功地从小体积血液和白皮毛中分离出了MNC。细胞培养物建立并保持3年无污染,细胞保持健康。利用磁珠成功分离CD4和CD45细胞,并成功进行冷冻和解冻。结论:在这项研究中,我们介绍了一种简单、经济、可靠的方法,用于从小体积的灰白色皮毛和血液中分离MNCs,适用于免疫学应用和磁珠细胞分离。这种方法是用户友好的,可以在世界各地的细胞培养实验室中采用,可能为开发新型抗体开辟新的途径,使用磁珠分离各种细胞群,并获得大量用于免疫疗法开发的t细胞,如CAR - t细胞疗法。关键词:单核细胞分离,黄皮,血液,CD4阳性细胞,磁珠

Objective: Acute renal failure (ARF) is a clinical syndrome that causes a decrease in the glomerular filtration rate and leads to an accumulation of nitrogenous waste products and uremic toxins. This study investigated the protective effect of Etanercept on ARF. Materials and Methods: Experiments were done on Balb-C female mice. Acute renal failure was created with an intraperitoneal folic acid injection. Etanercept was injected with folic acid in doses of 0.7 mg/kg, 3.5 mg/kg, and 7 mg/kg in treatment groups. Blood urea nitrogen levels, creatinine and cystatin-c were measured on the 7th day of the study. The kidneys were examined histologically with hematoxylin-eosin staining and Tunel assay. Results: Etanercept improved kidney morphology damaged by folic acid. The apoptotic index was low, and there was less dilation in the renal tubules in the groups treated with Etanercept. Folic acid increased blood urea nitrogen levels. This increase was decreased gradually with increased doses of Etanercept. There were no differences in creatinine levels in all groups. Conclusion: This study investigated the protective effects of Etanercept in the context of Acute Renal Failure (ARF). The results demonstrated that Etanercept improved kidney morphology damaged by folic acid, reduced the apoptotic index, and gradually decreased elevated blood urea nitrogen levels. Although creatinine levels showed no significant differences among the treatment groups, the findings suggest that Etanercept may hold promise as a potential agent for the treatment of ARF. Further research and clinical studies are warranted to validate its effectiveness and safety in human subjects.
目的:急性肾衰竭(ARF)是一种临床综合征,引起肾小球滤过率下降,导致含氮废物和尿毒症毒素的积累。本研究探讨依那西普对ARF的保护作用。材料与方法:以Balb-C雌性小鼠为实验对象。急性肾衰竭是由腹腔注射叶酸引起的。治疗组依那西普注射叶酸,剂量分别为0.7 mg/kg、3.5 mg/kg和7 mg/kg。在研究第7天测定血尿素氮、肌酐和胱抑素c水平。采用苏木精-伊红染色和Tunel法对肾脏进行组织学检查。结果:依那西普改善叶酸所致肾形态损伤。依那西普组大鼠肾小管细胞凋亡指数较低,扩张程度较轻。叶酸增加了血尿素氮水平。随着依那西普剂量的增加,这种增加逐渐减少。各组肌酐水平无差异。结论:本研究探讨依那西普对急性肾功能衰竭(ARF)的保护作用。结果表明,依那西普能改善叶酸损伤大鼠肾脏形态,降低细胞凋亡指数,并逐渐降低血尿素氮水平。尽管肌酐水平在治疗组之间没有显着差异,但研究结果表明依那西普可能有望成为治疗ARF的潜在药物。需要进一步的研究和临床研究来验证其在人类受试者中的有效性和安全性。

Objective: Since thyroid nodules have low malignant potential and thyroid cancers progress slowly, early diagnosis is important for a longer life expectancy. Fine needle aspiration (FNA) is a cost-effective method with an easy application, low complication rate and high diagnostic value. The aim of this study is to assess the diagnosis accuracy and prevalence of thyroid cancer by comparing the findings of FNA procedures performed in our center with definitive histopathology results of patients undergoing surgery after FNA and then comparing these results to the literature. Materials and Methods: Cytology reports of 1040 patients who underwent thyroid FNA between January 2021 and October 2022 were retrospectively evaluated. Definitive histopathology results of 146 patients who underwent total or subtotal thyroidectomy were compared with preoperative FNA cytology results. Thyroid cytological results were classified according to the 2017 Bethesda system diagnostic categories. Results: Cases with definitive histopathology results indicating malignancy accounted for 33.3% of non-diagnostic cases, 14.5% of benign, 18.5% of atypia or follicular lesion of undetermined significance (AUS)/FLUS, 33.3% of follicular neoplasm or suspected follicular neoplasm, 75.0% of suspected malignancy and 100% of malignant preoperative FNAC results. For malignant cases, FNA had a sensitivity of 47.5%, specificity of 98.1%, false-positive rate of 20.8%, false-negative rate of 17.2%, positive predictive value of 79.1%, negative predictive value of 82.8% and accuracy rate of 72.8%. Conclusion: In this study, the prevalence of thyroid cancer exceeded the cancer rates predicted by the 2017 Bethesda classification. Thyroid cancer may be predicted by the follow-up of patients with solitary or multiple nodules without a surgical indication, and a repeat FNA when necessary.
目的:由于甲状腺结节的恶性潜能低,甲状腺癌进展缓慢,早期诊断对延长预期寿命很重要。细针抽吸(FNA)是一种应用简单、并发症发生率低、诊断价值高、性价比高的方法。本研究的目的是通过比较本中心FNA手术的结果与FNA手术后患者的明确组织病理学结果,并将这些结果与文献进行比较,来评估甲状腺癌的诊断准确性和患病率。材料和方法:回顾性分析2021年1月至2022年10月期间1040例甲状腺FNA患者的细胞学报告。我们将146例甲状腺全切除术或次全切除术患者的组织病理学结果与术前FNA细胞学结果进行比较。甲状腺细胞学结果根据2017 Bethesda系统诊断分类进行分类。结果:组织病理学结果明确为恶性的病例占未诊断病例的33.3%,良性占14.5%,异型或意义不明的滤泡性病变(AUS)/FLUS占18.5%,滤泡性肿瘤或疑似滤泡性肿瘤占33.3%,疑似恶性占75.0%,术前FNAC结果为恶性的占100%。FNA对恶性病例的敏感性为47.5%,特异性为98.1%,假阳性率为20.8%,假阴性率为17.2%,阳性预测值为79.1%,阴性预测值为82.8%,准确率为72.8%。结论:在本研究中,甲状腺癌的患病率超过了2017年Bethesda分类预测的癌率。甲状腺癌可以通过对无手术指征的单发或多发结节患者的随访来预测,必要时进行重复FNA检查。

Objective: This study aimed to evaluate the validity and reliability of the Infection Prevention Behavior Scale of Individuals (IPBS-I) among Turkish individuals. Materials and Methods: This was a methodological validity and reliability study. A total of 309 individuals between the ages of 18-65 who met the inclusion criteria were enrolled. The IPBS-I was translated into Turkish using the translation-back-translation technique. Data were collected via the Personal Information Form (PIF), Turkish version of the IPBS-I (IPBS-I-TR), and Protective Behaviors Towards COVID-19 Scale (PBCS). Two weeks later, IPBS-I-TR evaluation was repeated. Confirmatory Factor Analysis (CFA) was performed for construct validity, and the PBCS was applied for criterion validity. Its reliability was evaluated using internal consistency, item analysis, and test-retest reliability. Statistical significance was set at p< 0.05. Results: In total, 309 individuals (183 women and 126 men) were enrolled in the study. The mean IPBS-I-TR was 4.09±0.64. The CFA results revealed ᵡ2=167.12, SD=51, and p=0.0001. It was determined that x²/SD was 3.277 in the model and that the model was compatible. The Standardized Root Mean Square Residual (S-RMR)=0.051, Comparative Fit Index (CFI)=0.929, Goodness of Fit Index (GFI)=0.917, and Root Mean Square Error of Approximation (RMSEA)=0.086 were determined to be within the acceptable range. The CFA supported the three-factor structure of the scale. The correlation coefficient with the PBCS was 0.639, confirming the criterion validity of the scale. The Cronbach's alpha coefficients of the entire scale and three subscales (“Blocking the Pathogen,” “Blocking Transmission,” and “Improving Immunity”) were 0.832, 0.826, and 0.725, respectively. The test-retest reliability of the entire scale and the three subscales was excellent (>0.80). Conclusion: The Turkish version of the IPBS-I was confirmed to have good reliability and validity for evaluating infection-prevention behaviors in Turkish society.
