    化疗引起的恶心和呕吐(CINV)是癌症治疗的一种使人衰弱的副作用,影响许多患者。大麻素激动剂,例如纳比酮和Δ9-四氢大麻酚(THC),大麻的主要精神活性成分,已显示出作为止吐药的功效。这里,我们报道了迈克尔·罗伯茨(MR)的病例,我们认为,他是英国国家卫生服务(NHS)为管理CINV的药用大麻花费用报销的第一位英国患者。医疗数据来自NHS记录和个人资助请求(IFR)表格。使用经过验证的问卷收集患者报告的结果指标(PROM),作为开始处方药用大麻的专业私人诊所的护理标准的一部分。患者表现为直肠乙状结肠腺癌伴肺转移。他收到了FOLFIRI(亚叶酸,氟尿嘧啶,和伊立替康)化疗,并接受了紧急哈特曼手术,随后进行了二线FOLFOX(亚叶酸,氟尿嘧啶,和奥沙利铂)化疗和肺消融。MR报告与初始FOLFIRI治疗相关的严重恶心和呕吐。止吐药甲氧氯普胺和阿瑞吡坦显示出适度的疗效。止吐药昂丹司琼,左甲丙嗪,和纳比隆与不能容忍的副作用有关。吸入以THC为主的大麻花与标准药物改善CINV相关,焦虑,睡眠质量,食欲,整体情绪,和生活质量。我们的结果增加了现有证据,表明药用大麻花可能在癌症姑息治疗与标准治疗肿瘤治疗相结合中提供有价值的支持。在这种情况下,成功的个人资助请求证明了其他患者获得这些治疗的途径。倡导在国家医疗保健服务中更广泛地认识和整合大麻基医药产品。
    Chemotherapy-induced nausea and vomiting (CINV) is a debilitating side effect of cancer treatment, affecting many patients. Cannabinoid agonists, such as nabilone and Δ9-tetrahydrocannabinol (THC), the main psychoactive component of Cannabis sativa L., have shown efficacy as antiemetics. Here, we report the case of Michael Roberts (MR), who we believe is the first British patient reimbursed by the National Health Service (NHS) England for the cost of medicinal cannabis flowers to manage CINV. Medical data were obtained from NHS records and individual funding request (IFR) forms. Patient-reported outcome measures (PROMs) were collected using validated questionnaires as part of the standard of care at the specialized private clinics where the prescription of medicinal cannabis was initiated. The patient presented with rectosigmoid adenocarcinoma with lung metastases. He received FOLFIRI (folinic acid, fluorouracil, and irinotecan) chemotherapy and underwent an emergency Hartmann\'s procedure with subsequent second-line FOLFOX (folinic acid, fluorouracil, and oxaliplatin) chemotherapy and lung ablation. MR reported severe nausea and vomiting associated with the initial FOLFIRI treatment. Antiemetics metoclopramide and aprepitant demonstrated moderated efficacy. Antiemetics ondansetron, levomepromazine, and nabilone were associated with intolerable side effects. Inhalation of THC-predominant cannabis flowers in association with standard medication improved CINV, anxiety, sleep quality, appetite, overall mood, and quality of life. Our results add to the available evidence suggesting that medicinal cannabis flowers may offer valuable support in cancer palliative care integrated with standard-of-care oncology treatment. The successful individual funding request in this case demonstrates a pathway for other patients to gain access to these treatments, advocating for broader awareness and integration of cannabis-based medicinal products in national healthcare services.

    目的:分析泌尿外科专业的诉讼趋势和索赔原因,在英国国家卫生服务(NHS)内,超过16年。
    方法:根据2000年《信息自由法》,从NHS决议中要求提供数据。这包括泌尿外科的索赔总数,成功(结算或关闭)的数量,以及2006年至2022年每个财政年度支付的损害赔偿费用。还收集了按主要原因分列的成功索赔。这些被编码为以下类别:\“非手术\”,\'术中\',\'术后\',和\'其他\'。
    结果:在2006年至2022年期间,共提出了4124项诉讼索赔,其中60.9%(2511/4124)的诉讼成功。总之,支付了1.45亿英镑(英镑)的赔偿金。从这16年的开始到结束,成功的索赔数量增加了2.9倍,支付的损害赔偿成本增加了10倍。关于成功索赔的主要原因,治疗失败或延误(20.9%,525/2511),诊断失败或延迟(14.5%,364/2511),术中问题(9.1%,229/2511)所占比例最高。总的来说,成功索赔的非手术原因占73.3%(1840/2511),术中20.1%(504/2511),术后为3.9%(98/2511)。
    结论:成功的泌尿外科诉讼索赔的数量,他们的相关成本正在上升。大多数是由于非手术原因,这可能部分解释为NHS等待名单以及2019年冠状病毒病(COVID-19)大流行的影响。
    OBJECTIVE: To analyse the litigation trends and the reasons for claims within the specialty of Urology, within the UK National Health Service (NHS), over a 16-year period.
    METHODS: Data were requested from NHS Resolution under the Freedom of Information Act 2000. This included the total number of claims in Urology, the number of these that were successful (settled or closed), and the costs in damages paid out per financial year between 2006 and 2022. A breakdown of the successful claims by their primary cause was also collected. These were coded into the categories: \'non-operative\', \'intraoperative\', \'postoperative\', and \'other\'.
    RESULTS: A total of 4124 litigation claims were made between 2006 and 2022 and 60.9% (2511/4124) of these claims were successful. In all, £145 million (British pounds) was paid out in damages. The number of successful claims increased 2.9-fold from the start to end of this 16-year period, and the costs in damages paid out increased 10-fold. Regarding primary causes for the successful claims, failure or delay in treatment (20.9%, 525/2511), failure or delay in diagnosis (14.5%, 364/2511), and intraoperative problems (9.1%, 229/2511) accounted for the highest proportion. Overall, non-operative causes for successful claims accounted for 73.3% (1840/2511), intraoperative for 20.1% (504/2511), and postoperative for 3.9% (98/2511).
    CONCLUSIONS: The number of successful urological litigation claims, and their associated costs is rising. The majority are due to non-operative causes, which may be partially explained by NHS waiting lists alongside the effects of the coronavirus disease 2019 (COVID-19) pandemic.

    本文探讨了“患者安全的时刻”-2000年左右的时期,当时患者安全成为英国国家卫生服务(NHS)的主要政策关注,和其他医疗保健系统。虽然医疗造成的伤害(医源性损伤)早已得到临床医生和科学家的认可,从2000年开始,NHS中出现了一种新的系统的患者安全语言,促进了对患者伤害的新型管理和监管方法.这种语言反映了国家在调节医疗保健方面的作用越来越大,以及医疗自主权的侵蚀和新的官僚管理形式的兴起。承认一个跨国公司,对患者安全的政策兴趣上升背后的知识背景——例如,工业安全科学见解的应用-本文考察了国内文化因素所起的作用,如医疗过失诉讼和医疗丑闻,帮助定义英国的新语言。
    This article explores the \'the moment of patient safety\'-the period around 2000 when patient safety became a key policy concern of the British National Health Service (NHS), and other healthcare systems. While harm caused by medical care (iatrogenic injury) had long been acknowledged by clinicians and scientists, from 2000 a new systemic language of patient safety emerged in the NHS that promoted novel managerial and regulatory approaches to patient harm. This language reflected the state\'s increasing role in regulating healthcare, as well as the erosion of medical autonomy and the rise of new forms of bureaucratic management. Acknowledging a transnational, intellectual context behind the rise of policy interest in patient safety-for example, the application of insights from the industrial safety sciences-this article examines the role played by domestic cultural factors, such as medical negligence litigation and healthcare scandals, in helping to define the new language in Britain.

    方法:这项回顾性队列研究使用了来自英国临床实践研究数据链和医院事件统计的数据。在主要分析中,将轻度PN(MiPN)患者与MSPN患者的年龄和性别进行匹配。患者在2007年4月1日至2019年3月1日期间纳入研究。计算了全因HCCU,包括初级和二级保健接触者和费用(成本年2022)。
    结果:在23,522名确定的患者中,8,933符合纳入标准,与2,479名PN患者的主要匹配队列。随访期间,MSPN组和MiPN组的匹配队列初级护理访视次数分别为21.27/患者年(PPY)和11.35PPY.MSPN和MiPN组的任何门诊量为10.72PPY和4.87PPY,分别。MSPN和MiPN组的门诊皮肤科访视为1.96PPY和1.14PPY,分别。
    结论:PN,尤其是MSPN,在英国有很高的HCCU负担,强调需要新的和改进的疾病管理治疗。
    Purpose: Prurigo nodularis (PN) is a skin disease characterized by intensely itchy skin nodules and is associated with a significant healthcare resource utilization (HCRU). This study aimed to estimate the HCRU of patients in England with PN overall and moderate-to-severe PN (MSPN) in particular.
    Methods: This retrospective cohort study used data from the Clinical Practice Research Datalink and Hospital Episode Statistics in England. Patients with Mild PN (MiPN) were matched to patients with MSPN by age and gender for the primary analysis. Patients were enrolled in the study between 1st April 2007 and 1st March 2019. All-cause HCRU was calculated, including primary and secondary care contacts and costs (cost-year 2022).
    Results: Of 23,522 identified patients, 8,933 met the inclusion criteria, with a primary matched cohort of 2,479 PN patients. During follow up, the matched cohort\'s primary care visits were 21.27 per patient year (PPY) for MSPN group and 11.35 PPY for MiPN group. Any outpatient visits were 10.72 PPY and 4.87 PPY in MSPN and MiPN groups, respectively. Outpatient dermatology visits were 1.96 PPY and 1.14 PPY in MSPN and MiPN groups, respectively.
    Conclusion: PN, especially MSPN, has a high HCRU burden in England, highlighting the need for new and improved disease management treatments.

    议会已对英国政府和NHS征收关税,旨在减少健康不平等。目的:了解政府政策对不平等的影响,这要求英国的NHS将择期手术外包给私营部门。我们分析了三个时间段内最少和最贫困的五分之一人群中髋关节和膝关节置换手术的入院人数:政策出台前(1997/98-2002/03);独立部门治疗中心计划实施后(2003/04-2006/07);以及“转诊时的选择”延长后(2007/08-2018/19)。结果:尽管髋关节和膝关节置换的入院率增加了一倍和两倍,分别,在1997/98年至2018/19年期间,不平等现象加剧,损害了最贫困的人群。在第3期,不平等以最快的速度增长;NHS的录取率下降,而私营部门的录取率继续上升。到2018/19年度,近三分之一的NHS资助程序是私下提供的。在1997/98年,每10名最贫困的五分之一人中就有10名接受髋关节和膝关节手术的患者,13和9,分别从最不被剥夺的人那里被接纳,到2018/19年,差距分别扩大到19和15。随着NHS治疗外包给私营部门的增加,髋关节和膝关节置换的社会经济不平等现象已经扩大。NHS必须重建内部能力和供应,而不是外包护理。
    Parliament has imposed duties on the government and NHS in England aimed at reducing health inequalities. AIM: to understand the effect on inequalities of government policies, which require the NHS in England to outsource elective surgery to the private sector. We analysed the numbers of admissions for hip and knee replacement surgery from the least and most deprived population quintiles in three time periods: before the introduction of the policies (1997/98-2002/03); following the implementation of the independent sector treatment centre programme (2003/04-2006/07); and after the extension of \'choice at referral\' (2007/08-2018/19). RESULTS: despite admission rates doubling and trebling for hip and knee replacements, respectively, between 1997/98 and 2018/19, inequality grew to the detriment of the most deprived. Inequality grew at the fastest rate during period 3; admission rates to the NHS fell while admissions to the private sector continued to rise. By 2018/19 almost a third of NHS funded procedures were provided privately. In 1997/98, for every 10 patients admitted for hip and knee surgery from the most deprived quintile, 13 and 9, respectively were admitted from the least deprived, by 2018/19 the gap had widened to 19 and 15, respectively. Socio-economic inequalities for hip and knee replacement have widened as outsourcing of NHS treatment to the private sector has increased. The NHS must rebuild in-house capacity and provision instead of outsourcing care.

    方法:从2021年2月开始,在英国癌症社区的十周内,使用滚雪球方法开发并传播了一项半结构化调查,确定从事临床实践的个人和机构,研究,和/或与低收入国家的合作伙伴进行教育。该调查已发送给NHS医院的个人,慈善机构,大学,其他组织,UKGCN成员,以及通过文献和网络搜索确定的联系人。
    结果:共发出639份邀请,收到88份答复。结果显示了一系列跨越癌症控制许多领域的合作努力:健康促进,预防,诊断和治疗,幸存者,和姑息治疗。来自撒哈拉以南非洲的许多国家都有代表,南美洲,中东和北非地区,中国,和东南亚。这些项目包括教育和培训(146),临床实践/护理(144),研究(226)。
    结论:这项制图工作表明,英国与低收入国家的利益相关者在所有三个教育领域进行了大量合作,临床护理,和研究。调查结果提供了一个初步框架,可从该框架中促进对英国全球肿瘤学界开展的广泛活动的深入战略情报。这些信息已被用作催化剂,以建立新的伙伴关系,并联系在类似地理位置工作的同事,鼓励双向学习。UKGCN将努力改善全球癌症服务的公平获取。
    OBJECTIVE: In 2020 the UK Global Cancer Network (UKGCN) was formed to unite those in the UK interested in Global Oncology and to strengthen collaborative partnerships with stakeholders working across low- and middle-income countries (LMICs) in cancer health systems, governance, and care. The UKGCN undertook a mapping exercise to document collaborations to inform the UK\'s global oncology strategy.
    METHODS: A semi-structured survey was developed and disseminated using a snowball method over ten weeks from February 2021 across the UK\'s cancer community, to identify individuals and institutions engaged in clinical practice, research, and/or education with partners in LMICs. The survey was sent to individuals in NHS hospitals, charities, universities, other organisations, UKGCN members, and to contacts identified by a literature and web search.
    RESULTS: A total of 639 invitations were sent, and 88 responses were received. Results demonstrate a range of collaborative efforts spanning many areas of cancer control: health promotion, prevention, diagnosis and treatment, survivorship, and palliative care. A wide range of countries were represented from Sub-Saharan Africa, South America, the MENA region, China, and South-East Asia. The projects included education and training (146), clinical practice/care (144), and research (226).
    CONCLUSIONS: This mapping exercise demonstrated considerable UK collaboration with stakeholders in LMICs across all three domains of education, clinical care, and research. The survey results provide an initial framework from which to promote in-depth strategic intelligence on the broad range of activities undertaken by the UK global oncology community. This information has been used as a catalyst to create new partnerships and connect colleagues working in similar geographical settings, encouraging bidirectional learning. The UKGCN will galvanise endeavours to improve equitable access to cancer services globally.

    背景:在没有增加资金或人员配备的情况下,大多数精神卫生保健提供者面临着对心理治疗需求增加的挑战。为了克服这种供需不平衡,护理提供者必须提高服务提供的效率。
    目的:在本研究中,我们研究了支持人工智能(AI)的数字解决方案是否可以帮助精神卫生保健从业者更有效地利用他们的时间,从而减轻服务压力,改善患者预后。
    方法:在本研究中,我们专注于使用AI解决方案(LimbicAccess)来支持英国国家卫生服务机构的初始患者转诊和临床评估.数据来自英格兰的9家谈话疗法服务机构,包括64,862名患者。
    结果:我们表明,使用此AI解决方案可以通过减少临床医生在心理健康评估上花费的时间来提高临床效率。此外,我们在几个关键指标中发现使用AI解决方案的患者的预后有所改善,例如减少等待时间,降低辍学率,改善对适当治疗途径的分配,and,最重要的是,提高回收率。在调查AI解决方案实现这些改进的机制时,我们发现,在临床评估之前提供临床相关信息对于这些观察到的效应至关重要.
    结论:我们的结果强调了使用AI解决方案来支持精神卫生劳动力的效用,进一步强调AI解决方案在提高医疗服务效率和改善患者临床结局方面的潜力.
    BACKGROUND: Most mental health care providers face the challenge of increased demand for psychotherapy in the absence of increased funding or staffing. To overcome this supply-demand imbalance, care providers must increase the efficiency of service delivery.
    OBJECTIVE: In this study, we examined whether artificial intelligence (AI)-enabled digital solutions can help mental health care practitioners to use their time more efficiently, and thus reduce strain on services and improve patient outcomes.
    METHODS: In this study, we focused on the use of an AI solution (Limbic Access) to support initial patient referral and clinical assessment within the UK\'s National Health Service. Data were collected from 9 Talking Therapies services across England, comprising 64,862 patients.
    RESULTS: We showed that the use of this AI solution improves clinical efficiency by reducing the time clinicians spend on mental health assessments. Furthermore, we found improved outcomes for patients using the AI solution in several key metrics, such as reduced wait times, reduced dropout rates, improved allocation to appropriate treatment pathways, and, most importantly, improved recovery rates. When investigating the mechanism by which the AI solution achieved these improvements, we found that the provision of clinically relevant information ahead of clinical assessment was critical for these observed effects.
    CONCLUSIONS: Our results emphasize the utility of using AI solutions to support the mental health workforce, further highlighting the potential of AI solutions to increase the efficiency of care delivery and improve clinical outcomes for patients.

    海外护士对英国(英国)并不陌生,牧师关怀的概念也不是。国际护士的巨大贡献是如此明显,以至于人们普遍认为这些护士将有一个强有力的关于牧养的文献基础。然而,情况恰恰相反。田园支持对于在英国以外招募的护士成功适应和融入NHS工作至关重要。为了提供全面的适合用途的支持,护士的观点很重要。
    本范围审查旨在确定对英国受过国际教育的护士的牧养支持的已知情况。
    使用范围审查方法来审查有关牧区支持的文献。
    现有文献提供了当前实践的证据,挑战,以及成功的牧区支持的结果标准。它还提供了有关早期牧师支持如何加强护士或取消他们的技能的证据。最后,它显示了海外护士获得的支持存在显着差异。
    虽然已经探索了先前适应计划的护士经验,关于当前牧区护理做法的证据大多在政策指导方针中找到,培训师报告,和意见片。自2014年NMC能力测试开始以来,牧养接受者的声音尚未被听到。这项范围界定审查表明,对牧区护理实践的理解存在差异。因此,在这个问题上,应该探讨黑非洲护士等特定群体的观点.
    UNASSIGNED: Overseas nurses are not new to the United Kingdom (UK), and neither is the concept of pastoral care. The immense contributions of international nurses are so obvious that it would be commonly assumed that there will be a strong literature base on pastoral care for these nurses. However, the opposite is very much the case. Pastoral support is crucial to the successful adaptation and integration of nurses who are recruited outside the United Kingdom to work within the NHS. To offer comprehensive fit-for-purpose support, the perspective of the nurses is important.
    UNASSIGNED: This scoping review aims to identify what is known about pastoral support for internationally educated nurses in the UK.
    UNASSIGNED: A scoping review method was used to review literature on pastoral support.
    UNASSIGNED: Existing literature provided evidence on current practices, the challenges, and outcome criteria for successful pastoral support. It also provided evidence on how early pastoral support can fortify the nurses or deskill them. Finally, it revealed significant disparities in the support received by overseas nurses.
    UNASSIGNED: While the nurses\' experience of the previous adaptation programme has been explored, evidence on the current pastoral care practices is mostly found in policy guidelines, trainers\' reports, and opinion pieces. Since the inception of the NMC test of competence in 2014, the voice of the recipients of pastoral care is yet to be heard. This scoping review suggests that there is a difference in understanding of pastoral care practices. Therefore, the perspectives of specific groups such as Black African nurses should be explored on this issue.

    方法:一万四百八十六名英国医学生。
    方法:医学生的职业意向,关注医学院之间的差异。次要结果包括医学生对NHS未来职业满意度的差异,医学院。
    结果:2.89%的学生打算完全离开医学,剑桥医学院的受访者比例最高。32.35%的受访者计划移民实习,阿尔斯特医学院的学生是最有可能的。在那些打算移民的人中,中央兰开夏大学表示无意返回的比例最高。加的夫医学院在完成FY2后打算担任非培训临床职位的学生比例最高。35.23%的参与医学生打算在毕业后2年内离开NHS,布莱顿和苏塞克斯在这些受访者中所占比例最高。只有17.26%的人对在NHS工作的前景感到满意,在全国范围内差异很大;Barts和伦敦医科学生的不满率最高。
    结论:这项研究揭示了英国医学院学生职业情绪的差异,强调需要注意影响这些趋势的因素。有相当比例的学生打算在毕业后的2年内退出NHS,机构之间有很大的差异。学生的意图可能受到各种因素的影响,包括课程重点和招聘实践。必须在医学院内重新评估这些方面,同时考虑到更广泛的国情,提高学生对NHS职业的看法。未来的研究应针对这些差异的根本原因,以促进职业满意度和保留率的提高。
    OBJECTIVE: To investigate differences in students\' career intentions between UK medical schools.
    METHODS: Cross-sectional, mixed-methods online survey.
    METHODS: The primary study included all 44 UK medical schools, with this analysis comprising 42 medical schools.
    METHODS: Ten thousand four hundred eighty-six UK medical students.
    METHODS: Career intentions of medical students, focusing on differences between medical schools. Secondary outcomes included variation in medical students\' satisfaction with a prospective career in the NHS, by medical school.
    RESULTS: 2.89% of students intended to leave medicine altogether, with Cambridge Medical School having the highest proportion of such respondents. 32.35% of respondents planned to emigrate for practice, with Ulster medical students being the most likely. Of those intending to emigrate, the University of Central Lancashire saw the highest proportion stating no intentions to return. Cardiff Medical School had the greatest percentage of students intending to assume non-training clinical posts after completing FY2. 35.23% of participating medical students intended to leave the NHS within 2 years of graduating, with Brighton and Sussex holding the highest proportion of these respondents. Only 17.26% were satisfied with the prospect of working in the NHS, with considerable variation nationally; Barts and the London medical students had the highest rates of dissatisfaction.
    CONCLUSIONS: This study reveals variability in students\' career sentiment across UK medical schools, emphasising the need for attention to factors influencing these trends. A concerning proportion of students intend to exit the NHS within 2 years of graduating, with substantial variation between institutions. Students\' intentions may be shaped by various factors, including curriculum focus and recruitment practices. It is imperative to re-evaluate these aspects within medical schools, whilst considering the wider national context, to improve student perceptions towards an NHS career. Future research should target underlying causes for these disparities to facilitate improvements to career satisfaction and retention.

    交联过程改善了生物聚合物基复合材料的物理化学性能,使它们对生物医学应用有价值。EDC/NHS交联的胶原蛋白材料在组织工程应用中具有巨大的潜力,由于其增强的性能和生物相容性。样品的化学交联可以通过几种方式进行,这是至关重要的,对所获得材料的最终性能有直接影响。在这项研究中,研究了交联条件对使用EDC和NHS的胶原膜性能的影响。研究包括FTIR光谱,AFM,溶胀和降解试验,机械测试和接触角测量。对制备的胶原膜的评估表明,交联剂和交联条件都会影响膜的性能。在样品的红外光谱中观察到明显的变化,将EDC直接添加到鱼胶原蛋白溶液中。相同的样品显示最低的杨氏模量,拉伸强度和断裂力参数和最高断裂伸长率。所有样品在PBS溶液中浸泡两小时后达到最大溶胀度;然而,浸渍交联的样品表现出明显较低的溶胀度,并且具有很高的耐久性。用EDC交联的胶原膜的粗糙度最高,而与添加NHS的EDC交联的样品观察到最低。交联剂增加了胶原膜的表面粗糙度,除了通过添加EDC和NHS混合物而改性的样品。所有膜的特征在于亲水特性。薄膜改性导致其亲水性和润湿性降低。我们的研究可以比较拟议的EDC/NHS交联条件及其对鱼胶原蛋白薄膜的物理化学性质的影响。EDC和NHS是用于生物医学应用中的鱼胶原蛋白改性的有前途的交联剂。
    The process of crosslinking improves the physicochemical properties of biopolymer-based composites, making them valuable for biomedical applications. EDC/NHS-crosslinked collagen materials have a significant potential for tissue engineering applications, due to their enhanced properties and biocompatibility. Chemical crosslinking of samples can be carried out in several ways, which is crucial and has a direct effect on the final properties of the obtained material. In this study, the effect of crosslinking conditions on the properties of collagen films using EDC and NHS was investigated. Studies included FTIR spectroscopy, AFM, swelling and degradation tests, mechanical testing and contact angle measurements. Evaluation of prepared collagen films indicated that both crosslinking agents and crosslinking conditions influenced film properties. Notable alternations were observed in the infrared spectrum of the sample, to which EDC was added directly to the fish collagen solution. The same sample indicated the lowest Young modulus, tensile strength and breaking force parameters and the highest elongation at break. All samples reached the maximum swelling degree two hours after immersion in PBS solution; however, the immersion-crosslinked samples exhibited a significantly lower degree of swelling and were highly durable. The highest roughness was observed for the collagen film crosslinked with EDC, whereas the lowest was observed for the specimen crosslinked with EDC with NHS addition. The crosslinking agents increased the surface roughness of the collagen film, except for the sample modified with the addition of EDC and NHS mixture. All films were characterized by hydrophilic character. The films\' modification resulted in a decrease in their hydrophilicity and wettability. Our research allows for a comparison of proposed EDC/NHS crosslinking conditions and their influence on the physicochemical properties of fish collagen thin films. EDC and NHS are promising crosslinking agents for the modification of fish collagen used in biomedical applications.
