Kinesophobia and its related factors in patients after percutaneous coronary intervention: A cross‐sectional study

Abstract

Objectives

To explore the postoperative kinesophobia of patients after percutaneous coronary intervention (PCI) and its related factors.

Background

Percutaneous coronary intervention is an effective method to treat coronary heart disease (CHD), and cardiac rehabilitation is an important auxiliary method after PCI. However, the compliance of patients with cardiac rehabilitation after PCI is not good, among which kinesophobia is an important influencing factor.

Design

A descriptive cross-sectional design was implemented, and the high-quality reporting of the study adhered to the Strengthening the Reporting of Observational Studies in Epidemiology Statement.

Methods

In total, 351 inpatients who underwent PCI in three tertiary grade-A hospitals in China were selected by convenient sampling method. We use one-way ANOVA and multiple linear regression analysis to determine the relevant related factors.

Results

The kinesophobia of patients after PCI was negatively correlated with chronic illness resource utilization and sense of personal mastery, and positively correlated with illness perception. Education level, clinical classification of CHD, exercise habits, chronic illness resource utilization, illness perception and sense of personal mastery entered the regression equation, which could explain 78.1% of the total variation.

Conclusion

The level of kinesiophobia of patients after PCI is high. Education level, clinical classification of CHD, exercise habits, chronic illness resource utilization, illness perception and sense of personal mastery are the related factors of kinesiophobia of patients after PCI.

Relevance to Clinical Practice

By reducing the level of exercise fear of patients after PCI, patients are more likely to accept and adhere to the cardiac rehabilitation plan, thus improving their prognosis and improving their quality of life.

Patient or Public Contribution

The patient underwent PCI in the research hospital. Researchers screen them according to the inclusion criteria and invite them to participate in this study. If they meet the requirements, participants will answer the research questionnaire face to face after signing the informed consent form.

The impact of early nutritional support on postoperative wound healing in patients with complex fractures: A meta‐analysis review

Abstract

Complex fractures present significant challenges in orthopaedic surgery, particularly in terms of postoperative wound healing. Nutritional status plays a crucial role in the recovery process, with early nutritional support potentially influencing wound healing outcomes. This meta-analysis aimed to assess the impact of early nutritional interventions on postoperative wound healing and scar formation in patients with complex fractures. From an initial pool of 1742 articles, 7 studies were selected for analysis. The results revealed that preoperative nutritional support significantly improved early wound healing, as indicated by lower REEDA scores (SMD = −14.06, 95% CI: [−16.79, −11.32], p < 0.01) 1 week post-surgery. Furthermore, there was a notable reduction in scar formation, as demonstrated by lower Manchester Scar Scale scores (SMD = −25.03, 95% CI: [−30.32, −19.74], p < 0.01) 3 months post-surgery. These findings highlight the importance of incorporating nutritional strategies into the management of complex fractures to optimize postoperative recovery.

Introduction

Trans young people are at a higher risk of mental health difficulties such as depression, anxiety and suicidality than their cisgender peers, due in part to their experiences of minority stress. This protocol describes a feasibility trial and subsequent pilot randomised controlled trial (RCT) of a codesigned group cognitive–behavioural therapy intervention for trans young people, named Trans Adolescent Group ThErapy for Alleviating Minority stress (TAG TEAM).

Methods and analysis

To evaluate TAG TEAM, we will conduct a feasibility trial followed by a pilot RCT with trans young people aged 14–16 years who have been referred to the Royal Children’s Hospital Gender Service in Melbourne, Australia. In the feasibility trial, we aim to enrol 32 participants who will be randomised at a 1:1 ratio to either in-person or online intervention arms. Participants will be assessed at baseline and post-treatment, with a nested qualitative evaluation post-treatment. Primary outcomes are the feasibility and acceptability of the intervention and the study design and associated procedures, including comparison of the in-person and online delivery modes. In the subsequent pilot RCT, we aim to enrol 64 participants who will be randomised at a 1:1 ratio to an intervention or waitlist control arm, with delivery mode determined by the feasibility trial. Participants will complete assessments at baseline, post-treatment and 3-month follow-up. Primary outcomes are the feasibility and acceptability of the RCT study design. In both the feasibility trial and pilot RCT, participants will complete assessments related to mood, anxiety, suicidality, quality of life, minority stress, family support and social transition. Quantitative data will be analysed using descriptive statistics. Qualitative data will be analysed using thematic and interpretive analysis.

Ethics and dissemination

The Royal Children’s Hospital Human Research Ethics Committee has approved this study (#91162). Informed consent will be obtained in writing from all participants and a legal guardian. Findings will inform the development of a full-scale RCT to evaluate the efficacy of TAG TEAM and will be disseminated through conferences and peer-reviewed journals.

PCAT‐1′ s role in wound healing impairment: Mitochondrial dysfunction and bone marrow stem cell differentiation inhibition via PKM2/β‐catenin pathway and its impact on implant osseo‐integration

Abstract

This study focused on unravelling the role of PCAT-1 in wound-healing process, particularly its impact on regenerative and osteogenic abilities of mesenchymal stem cells (MSCs). We delved into how PCAT-1 regulates mitochondrial oxidative phosphorylation (OXPHOS) and interacts with pivotal molecular pathways, especially β-catenin and PKM2, using human bone marrow-derived MSCs. MSCs were cultured under specific conditions and PCAT-1 expression was modified through transfection. We thoroughly assessed several critical parameters: MSC proliferation, mitochondrial functionality, ATP production and expression of wound healing and osteogenic differentiation markers. Further, we evaluated alkaline phosphatase (ALP) activity and mineral deposition, essential for bone healing. Our findings revealed that overexpressing PCAT-1 significantly reduced MSC proliferation, hampered mitochondrial performance and lowered ATP levels, suggesting the clear inhibitory effect of PCAT-1 on these vital wound-healing processes. Additionally, PCAT-1 overexpression notably decreased ALP activity and calcium accumulation in MSCs, crucial for effective bone regeneration. This overexpression also led to the reduction in osteogenic marker expression, indicating suppression of osteogenic differentiation, essential in wound-healing scenarios. Moreover, our study uncovered a direct interaction between PCAT-1 and the PKM2/β-catenin pathway, where PCAT-1 overexpression intensified PKM2 activity while inhibiting β-catenin, thereby adversely affecting osteogenesis. This research thus highlights PCAT-1's significant role in impairing wound healing, offering insights into the molecular mechanisms that may guide future therapeutic strategies for enhancing wound repair and bone regeneration.

Study protocol for a feasibility study of microinterventions in smartphone-based assessments to reduce depressive rumination

Por: Höller · I. · Spangenberg · L.
Introduction

Depression as well as suicidal ideation and behaviours share several precipitating and maintaining factors and are subject to the influence of overlapping constructs. One of these transdiagnostic constructs is rumination. For the treatment of rumination, a variety of interventions are already available. However, not everyone with a need receives psychotherapeutic treatment. And even if they do: implementing learnt strategies alone at home can be challenging for patients. Therefore, this study aims to test the feasibility of delivering microinterventions for the reduction of rumination in a smartphone-based setting with the goal to make these interventions accessible to a larger number of people and support their use in everyday life.

Methods and analysis

The study’s design is an uncontrolled-within-group design. Participants with at least mild depressive symptoms and reported rumination will be included and recruited via outpatient clinics as well as in the general population. The aim is to recruit at least N=70 participants. Participants first undergo a short telephone screening, a baseline assessment, a 7-day smartphone-based assessment including microinterventions in case participants report rumination and a postassessment. For feasibility purposes, primary outcomes relate to participants’ compliance, their evaluation of the smartphone-based assessment as well as the microinterventions delivered during the assessment. As a secondary goal, clinical utility will be examined. Clinical outcomes (eg, depressive symptoms, rumination) will be measured at baseline and postassessment.

Ethics and dissemination

The ethics committee of the institute of psychology of the university of Duisburg-Essen and University of Leipzig has approved the study. Study results will be disseminated to healthcare communities, in peer-reviewed science journals and at conferences.

Molecular evidence for potential transovarial transmission of Dabieshan tick virus in <i>Haemaphysalis longicornis</i> from Shandong Province, China

by Anan Wang, Yunfeng Tang, Zheng Pang, Yaxuan Gong, Jintao Wu, Jun Qi, Guoyu Niu

Dabieshan tick virus (DBTV) is a newly identified arbovirus, first detected in Haemaphysalis longicornis collected from Hubei Province in 2015. It has been confirmed that DBTV is widely distributed in Shandong Province, China. However, its entomological and epidemiological features remain to be further explored, particularly the feasibility of transovarial transmission. Our research tries to explain the possibility of transovarial transmission of DBTV from engorged female ticks to their offspring. All engorged female adult ticks were sampled from domestic sheep and allowed to lay eggs and hatch in appropriate laboratory conditions. All engorged ticks, larvae and unhatched eggs were classified into pools for nucleic acid extraction and DBTV RNA detection. According to the results of qRT-PCR, the positive rate of DBTV was 6.25% (8/128) in engorged female ticks, 3.57% (1/28) in eggs and 5% (3/60) in larvae pools, respectively. Phylogenetic analysis indicated that DBTV isolates from larvae were similar to those from maternal ticks with more than 99.5% homology, and DBTV was relatively conservative in evolution. Our findings are the first to provide molecular evidence of potential transovarial transmission of DBTV among H. longicornis. Nonetheless, the transovarial transmission of DBTV in frequency and proportion occurring in nature deserves further investigation.

Physiological changes of microalga <i>Dunaliella parva</i> under the treatment of PEG, CaCl<sub>2</sub>

by Qiman Zou, Limei Huang, Jinghui Gu, Bingbing Pang, Changhua Shang

Carotenoids are antioxidants, which reduce various chronic diseases of human, and have many industrial applications. The halophilic Dunaliella parva (D. parva) is rich in carotenoids. The compounds CaCl2 and PEG are the popular metabolic enhancers. To further enhance carotenogenesis, D. parva was treated with two compounds polyethylene glycol (PEG) and CaCl2. Application of CaCl2 and PEG enhanced the carotenoids contents and the antioxidant activities of carotenoids compared to control group (no treatment of CaCl2 or PEG). The highest carotenoids contents were obtained by treating D. parva with 40 ppm CaCl2 (3.11 mg/g dry weight, DW) and 80 ppm PEG (2.78 mg/g DW) compared with control group (1.96 mg/g DW). When D. parva was treated with 40 ppm CaCl2 and 80 ppm PEG, protein contents reached the highest values (90.28 mg/g DW and 89.57 mg/g DW) compared to that of control group (73.42 mg/g DW). The antioxidant activities of carotenoids samples were determined. Generally, the antioxidant activities of carotenoids from D. parva treated with PEG and CaCl2 were superior to that of control group. The antioxidant activities of carotenoids mainly contained reducing power, hydroxyl radical scavenging activity and superoxide radical scavenging activity. The reducing powers of carotenoids extracts from 20 ppm CaCl2 group (2.07%/mg carotenoids) and 120 ppm PEG group (1.59%/mg carotenoids) were significantly higher than that of control group (2 group (70.33%/mg carotenoids) and 80 ppm PEG group (65.94%/mg carotenoids) were significantly higher than that of control group (D. parva.

Effectiveness of transcranial direct current stimulation (tDCS) as adjunctive treatment for chronic headache in adults with clinically stable systemic lupus erythematosus (SHADE): a randomised double-blind multiarm sham controlled clinical trial

Por: Estiasari · R. · Tiksnadi · A. · Tunjungsari · D. · Maharani · K. · Aninditha · T. · Sofyan · H. R. · Savitri · I. · Pangeran · D. · Jeremia · I. · Widhani · A. · Ariane · A.
Background

Chronic headache is a ‘silent’ neuropsychiatric systemic lupus erythematosus symptom with heterogeneous prevalence, potentially reaching 54.4%. It may reduce quality of life by increasing the likelihood of depression and sleep disturbance. While pharmacotherapy remains the first-line treatment, the current management is still challenging and needs other non-invasive modalities. An effective, tolerable and disease-specific treatment modality including transcranial direct current stimulation (tDCS) is considered to reduce the frequency of chronic headaches, including in SLE. Until recently, there was no standard protocol for tDCS in treating headaches.

Methods and analysis

SHADE is a single-centre randomised double-blind multiarm sham-controlled trial for adults with clinically stable SLE, chronic headaches and without history of traumatic brain injury, brain infection, stroke or brain tumour. Random allocation is conducted to 88 subjects into 3 treatment groups (administration at primary motor, primary sensory and dorsolateral prefrontal cortex) and control group in 1:1:1:1 ratio. The primary endpoint is reduced number of headache days after adjunctive tDCS. The secondary endpoints are reduced headache intensity, increased quality of life, increased sleep quality, decreased depression and reduced analgesics use. The outcome is measured monthly until 3-month postintervention using headache diary, 36-Item Short Form Survey, Chronic Headache Quality of Life Questionnaire, Pittsburgh Sleep Quality Index and Mini International Neuropsychiatry Interview version 10 (MINI ICD 10). Intention-to-treat analysis will be performed to determine the best tDCS electrode placement.

Ethics and dissemination

Ethical approval had been obtained from the local Institutional Review Board of Faculty of Medicine Universitas Indonesia. Results will be published through scientific relevant peer-reviewed journals.

A protocol for evaluating the entomological impact of larval source reduction on mosquito vectors at hotel compounds in Zanzibar

by Ayubo Kampango, Fatma Saleh, Peter Furu, Flemming Konradsen, Michael Alifrangis, Karin L. Schiøler, Christopher W. Weldon

There is an increasing awareness of the association between tourism activity and risks of emerging mosquito-borne diseases (MBDs) worldwide. In previous studies we showed that hotels in Zanzibar may play an important role in maintaining residual foci of mosquito vectors populations of public health concern. These findings indicated larval sources removal (LSR) interventions may have a significant negative impact on vector communities. However, a thorough analysis of the response vector species to potential LSM strategies must be evaluated prior to implementation of a large-scale area-wide control campaign. Here we propose a protocol for evaluation of the impact of LSR against mosquito vectors at hotel settings in Zanzibar. This protocol is set to determine the efficacy of LSR in a randomized control partial cross-over experimental design with four hotel compounds representing the unit of randomization for allocation of interventions. However, the protocol can be applied to evaluate the impact of LRS in more than four sites. Proposed interventions are active removal of disposed containers, and installation of water dispenser to replace single use discarded plastic water bottles, which were identified as the most important source of mosquitoes studied hotels. The ideal time for allocating intervention to the intervention arms the dry season, when the mosquito abundance is predictably lower. The possible impact of interventions on mosquito occurrence and abundance risks is then evaluated throughout subsequent rainy and dry seasons. If an appreciable reduction in mosquito abundance and occurrence risks is observed during the trial period, intervention could be extended to the control arm to determine whether any potential reduction of mosquito density is reproducible. A rigorous evaluation of the proposed LRS interventions will inspire large scale trials and provide support for evidence-based mosquito management at hotel facilities in Zanzibar and similar settings.

Nurses' preparedness, opinions, barriers, and facilitators in responding to intimate partner violence: A mixed‐methods study

Abstract

Introduction

Intimate partner violence (IPV) is associated with multiple adverse health consequences. Nurses (including midwives) are well positioned to identify patients subjected to IPV, and provide care, support, and referrals. However, studies about nursing response to IPV are limited especially in low- and middle-income countries (LMICs). The study aimed to examine nurses' perceived preparedness and opinions toward IPV and to identify barriers and facilitators in responding to IPV.

Design

An explanatory sequential mixed-methods study was conducted by collecting quantitative data first and explaining the quantitative findings with qualitative data.

Methods

The study was conducted in two tertiary general hospitals in northeastern (Shenyang city) and southwestern (Chengdu city) China with 1500 and 1800 beds, respectively. A total of 1071 survey respondents (1039 female [97.0%]) and 43 interview participants (34 female [79.1%]) were included in the study. An online survey was administered from September 3 to 23, 2020, using two validated scales from the Physician Readiness to Manage Intimate Partner Violence Survey. In-depth, semistructured interviews were conducted from September 15 to December 23, 2020, guided by the Consolidated Framework for Implementation Research.

Results

The survey respondents largely agreed with feeling prepared to manage IPV, e.g., respond to discourses (544 [50.8%] of 1071) and report to police (704 [65.7%] of 1071). The findings of surveyed opinions (i.e., Response competencies; Routine practice; Actual activities; Professionals; Victims; Alcohol/drugs) were mixed and intertwined with social desirability bias. The quantitative and qualitative data were consistent, contradicted, and supplemented. Key qualitative findings were revealed that may explain the quantitative results, including lack of actual preparedness, absence of IPV-related education, training, or practice, and socially desirable responses (especially those pertaining to China's Anti-domestic Violence Law). Commonly reported barriers (e.g., patients' reluctance to disclose; time constraints) and facilitators (e.g., patients' strong need for help; female nurses' gender advantage), as well as previously unreported barriers (e.g., IPV may become a workplace taboo if there are healthcare professionals known as victims/perpetrators of IPV) and facilitators (e.g., nurses' responses can largely meet the first-line support requirements even without formal education or training on IPV) were identified.

Conclusions

Nurses may play a unique and important role in responding to IPV in LMICs where recognition is limited, education and training are absent, policies are lacking, and resources are scarce. Our findings support World Health Organization recommendations for selective screening.

Clinical Relevance

The study highlights the great potential of nurses for IPV prevention and intervention especially in LMICs. The identified barriers and facilitators are important evidence for developing multifaceted interventions to address IPV in the health sector.
