Introduction: Increasing and maintaining bone density can play a role in preventing osteoporosis, as changes in the trabecular bone score (TBS) and bone mineral density (BMD) affect bone density, especially in the spine. Objectives: The present study aimed to determine the level of agreement between TBS and BMD in patients with osteoporosis and also to investigate the relationship between these two indices with body mass index (BMI). Patients and Methods: Data were collected from 843 patients, referred to the densitometry department of Resalat hospital. BMD and TBS were measured in the subjects to determine the risk of osteoporosis. The results of BMD were measured based on T-score level. The patients’ individual and clinical characteristics were also recorded and factors influencing the prognosis of density changes were evaluated. Moreover, the effect of BMI was investigated in this study. Results: The mean age of patients was 55.5 years. The kappa coefficient and Spearman’s correlation coefficient of BMD and TBS were 0.004 and -0.015, respectively. There was a significant correlation between BMI and BMD in men. The kappa coefficient gradually increased from normal bone density to osteoporosis. There was a significant negative correlation between BMI and BMD, while a significant positive correlation between height and BMD in women was existed. On the other hand, a significant negative correlation between weight and BMD was detected accordingly. Conclusion: According to the results of our study, there is no agreement between BMD and TBS.
导论:增加和维持骨密度可以预防骨质疏松症,因为骨小梁评分(TBS)和骨矿物质密度(BMD)的变化会影响骨密度,尤其是脊柱。目的:本研究旨在确定骨质疏松症患者TBS和BMD之间的一致程度,并探讨这两个指标与体重指数(BMI)之间的关系。患者和方法:资料收集自Resalat医院密度测量科转诊的843例患者。测量受试者的骨密度和TBS以确定骨质疏松症的风险。以T-score水平测定骨密度。记录患者的个体及临床特征,评价影响密度变化预后的因素。此外,本研究还探讨了BMI的影响。结果:患者平均年龄55.5岁。骨密度与TBS的kappa系数和Spearman相关系数分别为0.004和-0.015。在男性中,BMI和BMD之间存在显著的相关性。从骨密度正常到骨质疏松,kappa系数逐渐增大。BMI与骨密度呈显著负相关,女性身高与骨密度呈显著正相关。另一方面,体重与骨密度呈显著负相关。结论:根据我们的研究结果,骨密度与TBS之间没有一致性。

Introduction: Overactive bladder (OAB) is a common condition in urology that affects individuals of various ages and genders, significantly impacting their quality of life. Objectives: The study aimed to examine the effectiveness of gabapentin in treating OAB in Jordan. Patients and Methods: This study was conducted at a private clinic in Jordan between 2020 and 2022. It utilized a one-group pre- and post-test design involving 50 patients. The intervention involved administering gabapentin at a daily dose of 400 mg. The effectiveness of gabapentin was evaluated using the overactive bladder symptom score (OABSS) questionnaire, administered before and after six weeks of gabapentin administration. Results: The study sample consisted of 50 patients aged between 45 and 85 years, with a mean age of 65.2 years. After the treatment, all individual variables, such as urgency, frequency, nocturia, and urgency incontinence, showed significant reductions compared to the pre-intervention values. The mean total OABSS significantly decreased from 14.6 before to 6.8 after the intervention. The paired t test yielded a result of 9.84 with a P value of less than 0.001, indicating a statistically significant improvement. Conclusion: The noteworthy improvement in OABSS scores, urgency, nocturia, frequency of micturition, and urge incontinence observed in this study suggests that gabapentin could have a role as a treatment option for OAB patients.

Introduction: Chronic hepatitis B (CHB) is a global concern due to its association with cirrhosis and hepatocellular carcinoma (HCC) development. The interplay between viral load, the immune system, and host factors is critical in tumorigenesis. Autophagy is a significant contributor to immune system function, since vitamin D plays an important role in this context. Objectives: The objective of this study was to assess the association between ATG5 (rs506027 and rs510432) and ATG16L1 (rs2241880 and ATG16 rs2241879) polymorphisms, viral load, and vitamin D with HBV pre-C/C mutations in Iraqi patients with CHB. Patients and Methods: In this cross-sectional study, a total of 134 CHB patients were evaluated for ATG polymorphisms, viral load, and vitamin D levels. Blood samples were collected after obtaining ethical consent, and the mutations were analyzed using polymerase chain reaction (PCR) followed by Sanger sequencing. Serum samples from CHB patients were used for viral load and vitamin D assessment. Results: The evaluation of patients revealed that 67 (44.6%) were male and 83 (55.4%) were female, with a mean age of 36±12.7 years and a mean duration of infection of 5.2±4.8 years. Mutations in pre-C/C were observed in 20% (27/134) of the patients. There was a significant association between all evaluated ATG polymorphisms and pre-C/C mutants (P<0.05). Furthermore, there was an association between viral load and mutations in pre-C/C (P=0.03), while no statistically significant difference was found between vitamin D levels and pre-core/core mutants or viral load. Conclusion: Our study demonstrates a higher frequency of ATG5 (rs506027 and rs510432) and ATG16L1 (rs2241880 and ATG16 rs2241879) polymorphisms, as well as a higher viral load in Iraqi CHB patients with HBV pre-C/C mutations.
慢性乙型肝炎(CHB)是一个全球关注的问题,因为它与肝硬化和肝细胞癌(HCC)的发展有关。病毒载量、免疫系统和宿主因子之间的相互作用是肿瘤发生的关键。自噬是免疫系统功能的重要贡献者,因为维生素D在此背景下起着重要作用。目的:本研究的目的是评估ATG5 (rs506027和rss510432)和ATG16L1 (rs2241880和ATG16 rs2241879)多态性、病毒载量和维生素D与伊拉克CHB患者HBV前C/C突变之间的关系。患者和方法:在这项横断面研究中,对134名慢性乙型肝炎患者进行了ATG多态性、病毒载量和维生素D水平的评估。获得伦理同意后采集血样,采用聚合酶链反应(PCR)分析突变,然后进行Sanger测序。采用慢性乙型肝炎患者血清样本进行病毒载量和维生素D评估。结果:男性67例(44.6%),女性83例(55.4%),平均年龄36±12.7岁,平均感染时间5.2±4.8年。在20%(27/134)的患者中观察到pre-C/C突变。所有评估的ATG多态性与预C/C突变体之间存在显著相关性(P<0.05)。此外,病毒载量与pre-C/C突变之间存在相关性(P=0.03),而维生素D水平与pre-core/core突变或病毒载量之间无统计学差异。结论:我们的研究表明,ATG5 (rs506027和rss510432)和ATG16L1 (rs2241880和ATG16 rs2241879)多态性的频率更高,并且在伊拉克CHB患者中HBV pre-C/C突变更高的病毒载量。

Introduction: Ovarian cancer is the sixth leading cancer-related mortality cause in women worldwide. Analgesics may hinder the occurrence of ovarian cancer through inflammation relief. The present study seeks to examine the relationship between analgesic consumption and ovarian cancer risk through a systematic review and meta-analysis. Materials and Methods: PubMed, Scopus, Web of Science, Cochrane databases, and Google Scholar search engines were searched for works published by May 2023 using standard keywords to collect the required data sources. Acquired data were then analyzed in STATA version14, considering a significance level of P < 0.05 in statistical tests. Results: The present meta-analysis comprised 21 studies (14 case-control and 7 cohort studies) performed on 53,755 subjects. Results indicated that taking aspirin reduced the risk of ovarian cancer by 8% (OR: 0.92; 95% CI: 0.87, 0.98), whereas other non-aspirin NSAIDs (non-steroidal anti-inflammatory drugs) did not significantly affect the ovarian cancer risk (OR: 0.91; 95% CI: 0.81, 1.02). Similar results were observed in the case of ibuprofen and acetaminophen, with non-significant relationships between the risk of ovarian cancer and with the consumption of both acetaminophen (OR: 0.95; 95% CI: 0.84, 1.08) and ibuprofen (OR: 0.76; 95% CI: 0.50, 1.14). Furthermore, the duration of analgesic consumption was not significantly linked to the risk of ovarian cancer in the case of all studied drugs. Conclusion: Among aspirin, ibuprofen, acetaminophen, and non-aspirin NSAIDs, only aspirin was found to reduce the risk of ovarian cancer in women while the other studied drugs did not influence the studied risk. However, further research is recommended to confirm the results. Registration: This study has been compiled based on the PRISMA checklist, and its protocol was registered on the PROSPERO (CRD42023434730) and Research Registry (UIN: reviewregistry1668) websites.
简介:癌症是全球第六大女性癌症相关死亡原因。镇痛药可能通过炎症缓解来阻碍卵巢癌症的发生。本研究旨在通过系统回顾和荟萃分析来检验镇痛药消耗与卵巢癌症风险之间的关系。材料和方法:PubMed、Scopus、Web of Science、Cochrane数据库和Google Scholar搜索引擎使用标准关键词搜索截至2023年5月发表的作品,以收集所需的数据源。然后在STATA版本14中分析所获得的数据,考虑到统计学检验中P<0.05的显著性水平。结果:本荟萃分析包括对53755名受试者进行的21项研究(14项病例对照研究和7项队列研究)。结果表明,服用阿司匹林可降低卵巢癌症风险8%(OR:0.92;95%CI:0.87,0.98),而其他非阿司匹林类非甾体抗炎药对卵巢癌症风险没有显著影响(OR:0.91;95%CI:0.81,1.02),卵巢癌症风险与对乙酰氨基酚(OR:0.95;95%CI:0.84,1.08)和布洛芬(OR:0.76;95%CI:0.50,1.14)的服用之间无显著关系。结论:在阿司匹林、布洛芬、对乙酰氨基酚和非阿司匹林类非甾体抗炎药中,只有阿司匹林能降低女性患卵巢癌症的风险,而其他研究药物对研究风险没有影响。然而,建议进行进一步的研究来证实这一结果。注册:本研究基于PRISMA检查表编制,其方案已在PROSPERO(CRD42023434730)和研究注册处(UIN:reviewregistry1668)网站上注册。

Introduction: It was essential to explore immunosuppressant management strategies and potential clinical variables associated with COVID-19 related mortality in order to provide insight for clinicians attempting to manage kidney transplant recipients during the ongoing severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) pandemic. Objectives: The aim of the study was to assess the impact of COVID-19 on post-transplant renal function and outcome of immunosuppressant management on COVID-19. Patients and Methods: This is a cross sectional observational study conducted from March 2020 to January 2022 in a tertiary care hospital in South India. Baseline characteristics, comorbidities, history of graft dysfunction, symptoms and immunosuppressant modification was noted. Outcomes of COVID-19 such as acute kidney injury (AKI), need for dialysis and post COVID-19 complications were noted. The statistics were expressed as percentage for categorical variables and mean ± SD for continuous variables. Results: Out of 400 renal transplant patients on regular follow up, 28 patients developed COVID-19. The incidence of AKI was 64.2%. Immunosuppressant dose modification was done in majority of patients [mycophenolate mofetil (28.5%), steroids (53.5%) and tacrolimus (39.2%)]. Outcomes included recovery from AKI in 61.1%, recovery from oxygen dependence in 100% patients with an overall mortality rate of 7.1% patients. About 17.8% patients developed post-COVID-19 complications. Conclusion: Immunosuppressant dose modification during COVID-19 could play a role in development of AKI; infection being an independent risk factor. Patients should be monitored for development of post-COVID-19 complications.
简介:有必要探索与新冠肺炎相关死亡率相关的免疫抑制剂管理策略和潜在临床变量,以便为临床医生在持续的严重急性呼吸综合征冠状病毒2(SARS-CoV-2)大流行期间尝试管理肾移植受者提供见解。目的:本研究的目的是评估新冠肺炎对移植后肾功能的影响以及免疫抑制剂管理对新冠肺炎的结果。患者和方法:这是一项2020年3月至2022年1月在南印度一家三级护理医院进行的横断面观察性研究。记录基线特征、合并症、移植物功能障碍史、症状和免疫抑制剂修饰。注意到新冠肺炎的结果,如急性肾损伤(AKI)、需要透析和新冠肺炎后并发症。统计数据以分类变量的百分比表示,连续变量的平均值±标准差表示。结果:在400名定期随访的肾移植患者中,28名患者出现新冠肺炎。AKI的发生率为64.2%。大多数患者都进行了免疫抑制剂剂量调整[霉酚酸酯(28.5%)、类固醇(53.5%)和他克莫司(39.2%)]。结果包括61.1%的患者从AKI中恢复,100%的患者从氧依赖中恢复,总死亡率为7.1%。约17.8%的患者出现新冠肺炎后并发症。结论:新冠肺炎期间免疫抑制剂剂量的改变可能在AKI的发展中起作用;感染是一个独立的危险因素。应对患者进行COVID-19后并发症的发展监测。

Thymomas are rare tumors that can present with a wide range of clinical characteristics. The presence of symptoms and paraneoplastic syndromes, such as myasthenia gravis, along with the histological subtype and stage of the tumor, are important factors that guide the treatment approach and prognosis for patients with thymomas. The prognosis for thymoma varies depending on several factors, including the stage and type of the tumor, as well as the presence of associated autoimmune diseases. Generally, early-stage thymomas have a better prognosis compared to advanced-stage tumors. Regular follow-up with a multidisciplinary team, including oncologists and thoracic surgeons, is essential for long-term management and surveillance of patients.
胸腺瘤是一种罕见的肿瘤,具有广泛的临床特征。症状和副肿瘤综合征的存在,如重症肌无力,以及肿瘤的组织学亚型和分期,是指导胸腺瘤患者治疗方法和预后的重要因素。胸腺瘤的预后取决于几个因素,包括肿瘤的分期和类型,以及相关自身免疫性疾病的存在。一般来说,与晚期肿瘤相比,早期胸腺瘤的预后更好。包括肿瘤学家和胸外科医生在内的多学科团队的定期随访对于患者的长期管理和监测至关重要。

Introduction: Postoperative pain control is one of the patient’s rights and the challenges of surgeons and anesthesiologists since about 20% of patients experience severe pain in the first 24 hours after surgery. Mastoidectomy and tympanoplasty are common surgeries in the head and neck area, in which profound and long-term analgesia is essential. Objectives: The present study investigated the effect of the combination of topical morphine, triamcinolone, and lidocaine compared to the control group. Patients and Methods: In the current clinical trial, 68 patients’ candidates for mastoidectomy-tympanoplasty surgery were included and randomly divided into intervention and control groups. The variables of demographic, pain, hemodynamics, extubation time, and received opioids were measured. Results: The results of the current study indicated a significant reduction in the patient’s pain scores in both groups (P=0.001), while the patients of group 1 had significantly lower pain scores than group 2 after 8, 12, and 24 hours in the ward (P<0.05). Moreover, a significant reduction was observed in systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) in all patients during surgery (P<0.001). However, in patients who received morphine, triamcinolone, and lidocaine (group 1), SBP and MAP were significantly lower than group 2 after 40, 80, 100, 120, 140, and 160 minutes during surgery (P<0.05). Conclusion: The present study indicated that the combination of morphine, triamcinolone, and lidocaine compared to the control group could lead to better pain control, further reduction of SBP and MAP, reduction of post-operative opioid use, and delay during the first opioid administration. Trial Registration: The trial protocol was approved by the Iranian Registry of Clinical Trials (identifier: IRCT20200825048515N39; https://irct.ir/trial/57931, ethical code; IR.MUI.MED.REC.1400.064).
引言:术后疼痛控制是患者的权利之一,也是外科医生和麻醉师的挑战,因为大约20%的患者在术后的前24小时内会出现剧烈疼痛。乳突切除术和鼓室成形术是头颈部常见的手术,其中深度和长期的镇痛至关重要。目的:与对照组相比,本研究调查了局部吗啡、曲安奈德和利多卡因联合使用的效果。患者和方法:在目前的临床试验中,68名乳突切除术鼓室成形术患者被纳入,并随机分为干预组和对照组。测量人口统计学、疼痛、血液动力学、拔管时间和接受阿片类药物的变量。结果:目前的研究结果表明,两组患者的疼痛评分均显著降低(P=0.001),而第1组患者在病房8、12和24小时后的疼痛评分显著低于第2组(P<0.05)。此外,观察到收缩压(SBP)、舒张压(DBP),和平均动脉压(MAP)(P<0.001)。然而,在接受吗啡、曲安奈德和利多卡因治疗的患者(1组)中,术中40、80、100、120、140和160分钟后,SBP和MAP显著低于2组(P<0.05),与对照组相比,利多卡因可以更好地控制疼痛,进一步降低SBP和MAP,减少术后阿片类药物的使用,并延迟首次阿片类药给药。试验注册:试验方案由伊朗临床试验注册处批准(标识符:IRCT20200825048515N39;https://irct.ir/trial/57931,道德规范;IR.MUI.MED.REC.1400.064)。

Introduction: Systemic sclerosis (SSc) is an autoimmune disorder that often presents with skin involvement. SSc affects various organs, and one of the most important of these organs is the cardiovascular system, which is one of the complications of this syndrome, including pulmonary arterial hypertension (PAH). Early diagnosis of this complication is very important due to the importance of the effect of PAH on mortality and morbidity of patients. For diagnosis of PAH, two methods of computed tomography (CT) scan and echocardiography are conducted. Objectives: In this study, we aimed to evaluate the agreement coefficient of chest CT scan in comparison with echocardiography in the diagnosis of PAH in patients with SSc. Patients and Methods: In a diagnostic study, which was conducted in Loghman hospital (Tehran-Iran), patients with a diagnosis of SSc were evaluated for pulmonary artery pressure (PAP) by echocardiography. For patients, a CT scan of the lungs was conducted and PAP was assessed. The results that obtained from the lungs CT scan were compared with the echocardiography results. Results: Fifty patients with SSc were evaluated. Eighty-four percent of patients were female and the mean age of all patients was 48.94 ± 11.02 years. About 16% of all patients had high PAP based on echocardiography and 28% of patients based on CT scan. Kappa’s agreement coefficient was 0.428 and Spearman’s correlation coefficient was 0.457. In other words, chest CT scan has a partly agreement with the echocardiography method (P value = 0.001). Conclusion: Chest CT scan has a high sensitivity, specificity, and accuracy compared to echocardiography as a screening method.
简介:系统性硬化症(SSc)是一种自身免疫性疾病,通常表现为皮肤受累。SSc影响多种器官,其中最重要的器官之一是心血管系统,这是该综合征的并发症之一,包括肺动脉高压(PAH)。由于多环芳烃对患者死亡率和发病率的影响非常重要,因此早期诊断这种并发症非常重要。对于PAH的诊断,采用CT扫描和超声心动图两种方法。目的:在本研究中,我们旨在评估胸部CT扫描与超声心动图诊断SSc患者PAH的一致系数。患者和方法:在伊朗德黑兰的Loghman医院进行的一项诊断研究中,诊断为SSc的患者通过超声心动图评估肺动脉压(PAP)。对患者进行肺部CT扫描并评估PAP。将肺部CT扫描结果与超声心动图结果进行比较。结果:对50例SSc患者进行了评估。女性占84%,平均年龄48.94±11.02岁。超声心动图显示约16%的患者PAP高,CT扫描显示约28%的患者PAP高。Kappa的一致系数为0.428,Spearman的相关系数为0.457。也就是说,胸部CT扫描与超声心动图方法部分一致(P值= 0.001)。结论:胸部CT扫描作为一种筛查方法,与超声心动图相比具有较高的敏感性、特异性和准确性。
