RESUMO

Background: A growing body of research shows that photodynamic therapy (PDT) has become an important mode of treatment in the field of lung cancer (LC) in recent years. Although numerous papers related to PDT in LC have been published, no bibliometric studies have been conducted to summarize the research prospects and highlight the research trends and hotspots in this field. This bibliometric analysis was conducted to investigate and provide a systematic understanding of the development of PDT research for LC over the past 13 years with the aim of providing a reference for new directions and strategies in the field of PDT for LC. Methods: In May 2023, relevant publications from the Web of Science Core Collection were downloaded, and CiteSpace and VOSviewer were used to conduct the scientometrics analysis in this study.Results: A total of 2,932 articles and reviews that met the inclusion criteria were retrieved, with China dominated the volume of publications from 2010 to 2022 and the most prolific institution was Shanghai Jiao Tong University. Conclusions: PDT can be utilized for the diagnosis and treat LC. Bronchoscopic fluorescence diagnosis using photosensitizers helps to detect tumor changes in the large bronchial mucosa. In the future, we should actively explore the use of new photosensitizers, including the development of nanomaterials, in addition, PDT combined with other treatments can significantly prolong survival. This combination therapy may also be the direction of future research.

RESUMO

AIM: The aim of this study is to determine the prevalence and risk factors for subsyndromal delirium in the postoperative patient. DESIGN: A systematic review and meta-analysis. METHODS: The Review Manager 5.3 statistics platform and the Newcastle-Ottawa Scale were used for quality evaluation. DATA SOURCES: The following databases were searched: PubMed, Web of Science, EMBASE, The Cochrane Library, Scopus and EBSCO from January 2000 to December 2021. Additional sources were found by looking at relevant articles' citations. RESULTS: A total of 1744 titles were originally identified, and five studies including 962 patients were included in the systematic review, with a pooled prevalence of postoperative subsyndromal delirium (PSSD) of 30% (95% CI: 0.28-0.32). Significant risk variables for PSSD were older age, low levels of education (≤9 years), cognitive impairment, higher comorbidity score, and the duration of operation. CONCLUSION: PSSD is prevalent and is associated with a variety of risk factors as well as low academic performance. IMPACT: Identification and clinical management of patients with PSSD should be improved. Future research on PSSD risk factors should look at a wider range of intraoperative and postoperative risk factors that can be changed. PATIENT AND PUBLIC CONTRIBUTION: No Patient or Public Contribution.

RESUMO

THE ETHNOPHARMACOLOGICAL SIGNIFICANCE: Diabetic chronic foot ulcers pose a significant therapeutic challenge as a result of the oxidative stress caused by hyperglycemia. Which impairs angiogenesis and delays wound healing, potentially leading to amputation. Gynura divaricata (L.) DC. (GD), a traditional Chinese herbal medicine with hypoglycemic effects, has been proposed as a potential therapeutic agent for diabetic wound healing. However, the underlying mechanisms of its effects remain unclear. AIM OF THE STUDY: In this study, we aimed to reveal the effect and potential mechanisms of GD on accelerating diabetic wound healing in vitro and in vivo. MATERIALS AND METHODS: The effects of GD on cell proliferation, apoptosis, reactive oxygen species (ROS) production, migration, mitochondrial membrane potential (MMP), and potential molecular mechanisms were investigated in high glucose (HG) stimulated human umbilical vein endothelial cells (HUVECs) using CCK-8, flow cytometry assay, wound healing assay, immunofluorescence, DCFH-DA staining, JC-1 staining, and Western blot. Full-thickness skin defects were created in STZ-induced diabetic rats, and wound healing rate was tracked by photographing them every day. HE staining, immunohistochemistry, and Western blot were employed to investigate the effect and molecular mechanism of GD on wound healing in diabetic rats. RESULTS: GD significantly improved HUVEC survival, decreased apoptosis, lowered ROS production, restored MMP, improved migration ability, and raised VEGF expression. The use of Nrf2-siRNA completely abrogated these effects. Topical application of GD promoted angiogenesis and granulation tissue growth, resulting in faster healing of diabetic wounds. The expression of VEGF, CD31, and VEGFR was elevated in the skin tissue of diabetic rats after GD treatment, which upregulated HO-1, NQO-1, and Bcl-2 expression while downregulating Bax expression via activation of the Nrf2 signaling pathway. CONCLUSION: The findings of this study indicate that GD has the potential to serve as a viable alternative treatment for diabetic wounds. This potential arises from its ability to mitigate the negative effects of oxidative stress on angiogenesis, which is regulated by the Nrf2 signaling pathway. The results of our study offer valuable insights into the therapeutic efficacy of GD in the treatment of diabetic wounds, emphasizing the significance of directing interventions towards the Nrf2 signaling pathway to mitigate oxidative stress and facilitate the process of angiogenesis.

RESUMO

Sanguisorba officinalis L., a traditional Chinese medicine, is frequently used to treat burns and scalds. But even so, it is unknown whether S. officinalis L. can accelerate diabetic wounds (DW) healing. Here, to bridge the gap, we employed in vivo and in vitro evaluations to assess the positive effect of S. officinalis L. ethanol extract (ESO) on DW. Results demonstrated that ESO dramatically improved the DW healing rate. With ESO treatment, the inappropriately elevated levels of IL6, IL1ß and TNFα in DW were reduced, while the expression of IL10 was increased, indicating that the abnormal inflammation in DW was also under control. Moreover, the abnormally elevated expression of CD86 was significantly inhibited and the expression of CD206 was significantly up-regulated following treatment with ESO. The global level of NF-κB protein was not affected by ESO treatment, but it suppressed the expression of phosphorylated NF-κB and prevented its nuclear entry. In addition, in RAW264.7 cells activated with lipopolysaccharide (LPS), the expression of NLRP3, Caspase1 and IL1ß were significantly diminished following ESO treatment. In conclusion, ESO was proved to be a promising treatment for DW healing due to its potential to accelerate the healing process by suppressing the inflammatory response. This was achieved by increasing the ratio of M2 to M1 polarization through blocking the NF-κB/NLRP3 signaling pathway.

RESUMO

Breast cancer is the most frequent cause of death from cancer in 12 regions of the world. Among the breast cancer subtypes, triple-negative breast cancer (TNBC) is the most aggressive, leading to an adverse prognosis. Thus, we aimed to identify the top 100 most cited articles regarding TNBC through bibliometric analyses, to explore their current impact and publication status. We searched TNBC-related articles from the Web of Science core database on September 19, 2021, and ranked them by citation in descending order. Information extracted from the top 100 most cited articles, included title, author, institution, country, year, publication, Journal Cited Rank, citation, Web of Science category, were extracted by two researchers independently. VOSviewer was used to analyze data, such as co-authoring institutions, and author cooperation. Descriptive statistical analysis of data was performed using Excel. Citations from the top 100 most cited articles ranged from 225 to 2753, and all were published after 2007. The top 100 most cited articles were published in 38 journals, with the Journal of Clinical Oncology published the most (n = 15), followed by Clinical Cancer Research (n = 11), Lancet Oncology(n = 6). Eric P. Winer from USA, who participated 12 articles, was the most frequently published author. The USA (n = 71) was the country with the most contributions to TNBC. The most prevalent topics included: clinical features, molecular subtypes, relevant influencing factors, exploration of treatment options and prognosis of TNBC. The leading institution was the Dana Farber Cancer Institute (n = 20) from the USA. This is the first bibliometric analysis on the TNBC 100 most cited article. We provided insights into the most cited articles on TNBC and listed a detailed description of their characteristics and trend, which provides ideas for further study.

RESUMO

BACKGROUND: Breathing exercise has been utilized as a promising approach to pain management in cancer survivors. However, the development process of the breathing exercise intervention protocol was rarely reported. AIM: To develop an evidence-based breathing exercise intervention protocol for chronic pain management in breast cancer survivors and to provide a detailed account of the intervention development process. METHODS: The study design was guided by the Medical Research Council Framework for Developing and Evaluating Complex Intervention. The breathing exercise intervention development process adopted phase one of the Medical Research Council Framework for Developing and Evaluating Complex Intervention framework. The content validity index was applied to determine the consensus of the appropriateness of the breathing exercise intervention protocol among the panel experts. RESULTS: The preliminary breathing exercise intervention protocol was developed based on fight-or-flight theory and vagus nerve theory, and the best available research evidence identified from seven systematic reviews, three clinical trials, and four practice recommendations. The breathing exercise intervention was designed as slow deep pursed-lip breathing with a time ratio of inspiration to expiration 1:2-3. The intensity of the breathing exercise was determined as 3 to 5 sessions a day, 5 minutes per session, for 4 weeks. The content validity of the breathing exercise intervention protocol was excellent as consensus was achieved among all panel experts with both the item-level and scale-level CVIs reaching 1.0. CONCLUSIONS: This study developed an evidence-based breathing exercise intervention protocol for chronic pain management in breast cancer survivors. The protocol is well-supported by the relevant theories, research evidence, practice recommendations, and experts' consensus.

RESUMO

INTRODUCTION: Chronic pain is a common symptom significantly affecting the quality of life of breast cancer survivors. Despite the achievement of pharmacological interventions, the barriers associated with this approach such as inaccessibility, misuse and side effects drive research into effective non-pharmacological interventions to improve chronic pain management, quality of life, anxiety and depression. Breathing exercise (BE) can be a promising option, but research evidence is sparse. This pilot study aims to examine the feasibility and preliminary effect of using an evidence-based BE intervention for chronic pain management in breast cancer survivors. METHOD AND ANALYSIS: This study will be a two-parallel-arm, open-labelled, phase II randomised controlled trial with 1:1 allocation. Seventy-two participants will be recruited from a tertiary hospital in China and randomly allocated to either a BE intervention group (n=36) or a control group (n=36). The participants in the intervention group will receive the usual care, a pain information booklet and a 4-week self-administered BE intervention; the participants in the control group will receive the usual care and the pain information booklet only. The assessment will be conducted at three time points: baseline (week 0), immediately after the intervention completion (week 5) and 4 weeks after the intervention completion (week 9). The primary outcomes will be the acceptability and feasibility assessment of the study protocol and methodological procedures. The secondary outcomes will be the effects of BE on pain, quality of life, anxiety and depression in breast cancer survivors. Descriptive statistics will be applied to present the primary outcomes and the Generalised Estimating Equation Model will be utilised to analyse the clinical outcomes. ETHICS AND DISSEMINATION: This study has received ethical approvals from the Human Research Ethics Committee at Charles Darwin University (H21089) and the Clinical Trial Ethics Committee at the Affiliated Hospital of Southwest Medical University (KY2022107). Findings from this study will be presented at academic conferences and submitted to peer-reviewed journals for publication. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov: NCT05257876.

RESUMO

BACKGROUND: Aromatase inhibitor (AI)-induced joint pain is a common toxicity of AI treatment. Although many studies have been conducted to examine the occurrence and severity of AI-induced joint pain in breast cancer survivors, none of the studies focused on the Chinese population with breast cancer. Given that the differences in cultural background and the genetic structure between Asians and Caucasians may contribute to different phenotypes of joint pain, this cross-sectional study was therefore conducted to examine the prevalence of AI-induced joint pain among Chinese breast cancer survivors receiving AI treatment and the correlates of pain. METHODS: This cross-sectional study was conducted in a tertiary hospital in China. Breast cancer survivors undergoing AI treatment were recruited to complete the following questionnaires: a self-designed baseline data form, the Nordic Musculoskeletal Questionnaire (NMQ), the Brief Pain Inventory (BPI), the 36-Item Short Form Health Survey (SF-36), and the Functional Assessment of Cancer Therapy-Breast (FACT-B). Based on the assessment results of NMQ (if the participant indicated pain in specific body parts), participants were then invited to complete other questionnaires to specifically assess the joint symptoms, including the Oxford Knee Score (OKS), the Oxford Hip Score (OHS), the Michigan Hand Outcomes Questionnaire (MHQ), and the Manchester Foot Pain Disability Questionnaire (MFPDQ). Descriptive analysis was used to analyse participants' baseline data and the prevalence of pain. Stepwise multiple regression was used to identify the correlates of pain. RESULTS: Four hundred and ten participants were analysed. According to the NMQ, 71.7% of the participants experienced joint symptoms in at least one joint, and the most frequently mentioned joint was knee (39.0%). The diagram in BPI indicated that 28.0% of the participants had the worst pain around knees. In patients with knee pain, the mean OKS score was 40.46 ± 6.19. The sub-scores of BPI for pain intensity and pain interference were 1.30 ± 1.63 and 1.24 ± 1.79, respectively. Patients' poorer physical well-being/functioning, previous use of AI treatment, presence of osteoarthritis, and receiving of physiotherapy were identified as four common correlates of greater severity of pain and pain interference (p < 0.05). CONCLUSIONS: Chinese breast cancer survivors can experience joint pain at various locations, particularly knees. In addition to increasing the use of interventions for pain alleviation, a comprehensive assessment of survivors' conditions such as physical functioning, history of AI treatment, and presence of osteoarthritis should be emphasized to identify survivors who need more attention and tailored interventions.

RESUMO

Objective: To test the validity, reliability, and acceptability of the Oxford Knee Score (OKS) Mandarin Chinese version for measuring knee pain and function among Chinese breast cancer survivors. Methods: This validation study was a secondary analysis of a cross-sectional survey that was conducted at the Affiliated Hospital of Southwest Medical University, Sichuan, China. Recruited from a larger arthralgia-related survey cohort, those who experienced knee arthralgia and completed the OKS Chinese version were selected for the current analysis. The Cronbach's alpha coefficient was calculated to identify the internal consistency reliability of the OKS. Spearman's correlations were adopted to identify the concurrent validity of the OKS. The discriminate performance of the OKS via subgroup analysis of breast cancer survivors with or without arthritis, as well as different exercise levels, cancer stages, chemotherapy protocols, and occupations, was also conducted. Results: One hundred and fifty-nine breast cancer survivors were included. There were significant correlations between the OKS and the FACT-B, the SF-36, and the BPI in measuring knee pain symptoms and their impact on daily living activities. The Cronbach's alpha for the OKS total scores was 0.90. The participants with arthritis reported significantly lower OKS scores than those without arthritis (P â€‹= â€‹0.040). The difference in OKS total scores between the participants with different exercise levels (P â€‹< â€‹0.001) and the participants with different occupations (P â€‹= â€‹0.006) was statistically significant. Considerable ceiling effects (>15%) of the OKS Chinese version were found in 11 of 12 items. Conclusions: The OKS Mandarin Chinese version is a short, valid, reliable, and sensitive tool for knee pain and function assessment among breast cancer survivors.

RESUMO

INTRODUCTION: The fatigue-sleep disturbance-depression (FSD) symptom cluster, as one of the most common symptom clusters in breast cancer (BC) survivors, can significantly decrease patients' quality of life. Since the management of the FSD symptom cluster has been unsatisfactory with the use of pharmacological treatments alone, non-pharmacological approaches have, therefore, been recommended. Somatic acupressure (SA) is a promising approach given its potential benefits of cancer-related symptom alleviation and the convenience of self-practice. However, research evidence on using acupressure to manage the FSD symptom cluster has been limited. The proposed trial aims to examine the feasibility and preliminary effects of an evidence-based SA intervention for FSD symptom cluster management in BC survivors. METHODS AND ANALYSIS: This study will be a phase II randomised controlled trial with three study arms and 1:1:1 allocation. Fifty-one early-stage BC survivors who are experiencing the FSD symptom cluster will be randomly assigned to a true SA group, a sham SA group or a usual care group. All participants will receive an education booklet regarding FSD symptom cluster management advice as the usual care package. The participants in the true SA group will additionally receive a 7-week self-administered SA intervention. The participants in the sham SA group will additionally receive self-administered light acupressure at non-acupoints with the same frequency, session and duration as the true SA group. The primary outcomes will be feasibility outcomes related to subject recruitment and completion of study questionnaires and interventions. The secondary outcomes will be the effects of SA on fatigue, sleep disturbance, depression and quality of life. Descriptive statistics will be used to present all the outcomes. The secondary outcomes will be analysed using an intent-to-treat approach. ETHICS AND DISSEMINATION: Ethical approvals of this trial have been granted by the Human Research Ethics Committee at Charles Darwin University (H19017) and the Clinical Trial Ethics Committee at The Affiliated Hospital of Southwest Medical University (KY2019039). Findings from this trial will be published in peer-reviewed journals and presented at professional conferences. TRIAL REGISTRATION NUMBER: This trial was registered at ClinicalTrials.gov and the registration number is NCT04118140, with the stage at Recruiting.

RESUMO

BACKGROUND AND PURPOSE: This study aimed to identify the research evidence on acupoint stimulation (AS) for cancer-related fatigue (CRF) management. METHODS: Randomised controlled trials that utilised AS for CRF management were retrieved. The Cochrane Back Review Group Risk of Bias Tool was used for quality appraisal. RevMan 5.3 was used for meta-analysis. RESULTS: Fifteen studies were included. Both the overall (SMD = -0.95, p = 0.008) and sub-group (acupuncture: SMD = -1.25, p = 0.002; short-term AS: SMD = -0.95, p = 0.02; medium-term AS: SMD = -0.96, p = 0.003) analyses indicated that AS was more effective in alleviating CRF than standard treatment/care. A comparison between the true and sham AS interventions favoured the true AS for CRF management, although the difference did not reach statistical significance. CONCLUSION: This study identified a promising role of AS in improving CRF. However, the study findings should be interpreted prudently due to the limited quality and sample sizes of some of the included studies.

RESUMO

BACKGROUND: Studies in the West have demonstrated that appropriate informational support is a vital component of cancer care, with positive effects on both patients and their informal caregivers. Since little is known about the information needs of advanced cancer patients and informal caregivers in China, where 'silence as virtue' is much more valued and the communication style is less open, this study was therefore conducted to elaborate the information needs of advanced cancer patients and informal caregivers as well as to explore their perceptions and experiences regarding their unmet information needs in the Chinese context. METHODS: This sub-study of a previous cross-sectional survey utilized a qualitative descriptive study design. The approach involved semi-structured interviews that followed an interview guide to collect data. Eligible participants were the advanced cancer patients and informal caregivers who had participated in the previous cross-sectional survey and reported unmet information needs. Each interview was audio-recorded and transcribed verbatim. Descriptive content analysis was used to analyze the data. RESULTS: Seventeen advanced cancer patients and 15 informal caregivers with unmet information needs participated in the semi-structured interviews, with ages ranging from 32 to 63 years old for patients and from 32 to 70 for informal caregivers. Four categories were extracted from the interviews with the patients and caregivers: (1) types of unmet information needs; (2) reasons for information needs not being met; (3) preferences for the provision of information; and (4) meaning and role of information. Each category had two to four sub-categories for both the patients and the caregivers, which were similar but not completely the same. CONCLUSION: The findings indicated that the provision of appropriate information could promote informed decision-making and greater satisfaction with treatment options, reductions in psychological disturbances, and enhanced confidence and ability in self-management and capacity in caregiving. Moreover, information on Traditional Chinese Medicine and food therapy should be increased, particularly for patients at the follow-up stage, while the amount of information on prognosis should be flexible as it could increase patients' and caregivers' psychological burden. Healthcare professionals were the most preferred information provider, although their heavy workload resulted in time constraints. In this case, they should provide information to patients and caregivers together as a 'whole unit.' At the same time, the value of separate conversations should also be recognized as some caregivers preferred to conceal unpleasant information from the patient.

RESUMO

Variability and factors influencing quality of life (QOL) in breast cancer patients having chemotherapy were examined in a longitudinal prospective cohort study in two teaching hospitals in China. Physical, mental, social/family, and functional QOL changed significantly over time with varying patterns. In addition, various factors influenced the QOL of breast cancer patients at each chemotherapy cycle. Health professionals should focus on critical time periods during chemotherapy, particularly at baseline and during the fourth and fifth cycles when the QOL in our sample was at the lowest point, and they should provide additional support to patients to ensure that chemotherapy is delivered in an optimal fashion.

RESUMO

Pancreatic cancer is one of the most severe types of tumors, with a 5-year survival rate of less than 7%. The prognosis and treatment of pancreatic cancer are largely limited by the extent of tumor invasion and the presence of lymph node and distant metastases. Therefore, exploring the biological behavior of pancreatic cancer cells (PCCs) is extremely important for the understanding, diagnosis, and treatment of pancreatic cancer. Current studies have shown that pancreatic stellate cells (PSCs) regulate the biological behavior of PCCs, such as their proliferation, apoptosis, invasion, and migration, by remodeling the extracellular matrix. Though Hic-5 is an important gene in PSCs, no study has investigated the regulation of PCCs by Hic-5. Here, we demonstrate that Hic-5 expression is upregulated in pancreatic cancer and that siRNA transfection can effectively inhibit Hic-5 expression. Compared to the control group, Hic-5 inhibition significantly reduced proliferation, increased apoptosis, and reduced invasion and migration of PCCs. Moreover, the inhibition of Hic-5 expression simultaneously reduced matrix metalloproteinase-9 (MMP-9) expression. Statistical analysis revealed that Hic-5 expression was higher among the pancreatic cancer group than among the normal group and was negatively correlated with postoperative survival time among patients with pancreatic cancer. These results have important clinical significance for further exploring the molecular mechanism involved in Hic-5-mediated invasion and metastasis of pancreatic cancer and ameliorating the prognosis of patients with pancreatic cancer.

RESUMO

Targeting on the IKKß to discover anti-inflammatory drugs has been launched for ten years, due to its predominant role in canonical NF-κB signaling. In the current study, we identified a novel IKKß inhibitor, ellipticine (ELL), an alkaloid isolated from Ochrosia elliptica and Rauvolfia sandwicensis. We found that ELL reduced the secretion and mRNA expression of TNF-α and IL-6 and decreased the protein expression of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) in bone marrow derived macrophages (BMDMs) stimulated with LPS. In coincided with the results, ELL suppressed PGE2 and NO production in BMDMs. Underlying mechanistic study showed that ELL inhibited IκBα phosphorylation and degradation as well as NF-κB nuclear translocation, which was attributed to suppression of IKKα/ß activation. Furthermore, kinase assay and binding assay results indicated that ELL inhibited IKKß activity via directly binding to IKKß and in turn resulted in suppression of NF-κB signaling. To identify the binding sites of ELL on IKKß, IKKßC46A plasmid was prepared and the kinase assay was performed. The results demonstrated that the inhibitory effect of ELL on IKKß activity was impaired in the mutation, implying that anti-inflammatory effect of ELL was partially attributed to binding on cysteine 46. Furthermore, ELL up-regulated LC3 II expression and reduced p62 expression, suggesting that autophagy induction contributed to the anti-inflammatory effect of ELL as well. In coincided with the in vitro results, ELL increased the survival and antagonized the hypothermia in the mice with LPS-induced septic shock. Consistently, ELL reduced TNF-α and IL-6 production in the serum of the mice treated with LPS. Collectively, our study provides evidence that ELL is an IKKß inhibitor and has potential to be developed as a lead compound for treatment inflammatory diseases in the future.
