The moderating role of catastrophizing in day-to-day dynamic stress and depressive symptoms.

The way individuals handle daily stressors can significantly influence their mental health. Those who struggle with emotion regulation are especially vulnerable to the negative effects of stress. This study explored the role of catastrophizing, a maladaptive emotion regulation strategy, in shaping the relationships between daily stress responses and depressive symptoms. A total of 75 healthy college students participated in the study. We adopted an Ecological Momentary Assessment protocol over 14 consecutive days to capture the day-to-day dynamics of stress reactivity and recovery. Our findings indicate that individuals with higher levels of catastrophizing exhibited increased daily stress reactivity and delayed daily stress recovery, consequently raising their likelihood of experiencing amplified depressive symptoms. In contrast, those with lower levels of catastrophizing did not experience the same negative effects of increased daily stress reactivity on their mental health. These results enhance understanding of how real-life stressors contribute to the development of mental health issues and underscore the importance of adaptive emotion regulation for improved overall health and well-being.

The meaning of respect and dignity for intensive care unit patients: A meta-synthesis of qualitative researches.

AIM: To synthesize qualitative research on perspectives and understandings of Intensive Care Unit (ICU) patients, family members, and staff regarding respect and dignity in ICU, in order to explore the connotations and meanings of respect and dignity in ICU. DESIGN: A qualitative meta-synthesis. METHODS: The Chinese and English databases were systematically searched, including PubMed, Web of Science, CINAHL, Embase, Cochrane Library, CNKI, Wangfang Data, VIP, and CBM from each database's inception to July 22, 2023. Studies were critically appraised using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Qualitative Research. Qualitative data were extracted, summarized, and meta-synthesized. (PROSPERO: CRD42023447218). RESULTS: A total of 9 studies from 6 countries were included in the meta-synthesis. Thirty-six main themes and 67 sub-themes were extracted, which were eventually integrated into 9 categories and 4 themes: (1) integrity of humanity; (2) autonomy; (3) equality; (4) environmental support. CONCLUSION: To maintain patient dignity, it is necessary to create an environment of respect within the ICU where healthcare professionals uphold the concept of preserving human integrity and respect patients' autonomy and equality. Healthcare professionals need to value the dignity of ICU patients and treat them as unique individuals during treatment and care. Hospital managers should also strive to create a respectful environment to provide environmental support for dignity care implementation.

The effectiveness of Interpersonal Psychotherapy-Adolescent Skills Training for adolescents with depression: a systematic review and meta-analysis.

Background: Interpersonal Psychotherapy-Adolescent Skills Training (IPT-AST) is a standardized depression prevention program for adolescents conducted in campus settings. The purpose of this review is to examine the randomized controlled trials of IPT-AST for the prevention of adolescent depression in the past 20 years. Methods: A systematic search of relevant electronic databases (PubMed, WOS, Embase, PsycINFO, the Cochrane Library, CNKI and WANFANG DATA) and study reference lists was conducted. Any study investigating the effectiveness of IPT-AST in 12- to 20-year-olds with depressive symptoms was eligible. Synthesis was via narrative summary and meta-analysis. Results: A total of 6 studies met the inclusion criteria. Meta-analysis results showed a remarkable improvement in patients' depressive symptoms after IPT-AST intervention (WMD = -5.05, 95% CI = -8.11 to -1.98, p < 0.05, I2 = 77%). Six month follow-up data showed that the intervention outcomes of IPT-AST remained significant (WMD = -3.09, 95% CI: -5.23 to -0.94, p < 0.05, I2 = 57%). Conclusion: This meta-analysis showed that IPT-AST was effective in adolescents with depressive symptoms at post-prevention and at 6-month follow-up. However, these conclusions are cautious, as they are based on a small number of studies and the presence of author duplication. Future studies should use multi-center, large-sample randomized controlled trials to evaluate the efficacy of IPT-AST for preventing depression in adolescents.

Open people are more likely to trust their new team members under subliminal influence.

The activation of subliminal stimuli plays an indispensable role in trust research. This study aimed to investigate the effect of subliminal stimuli on team trust and the moderating role of openness on the relationship between subliminal stimuli and team trust. A total of 155 participants were recruited to complete five tasks. The results suggested a significant influence of subliminal stimuli on team trust and the significant moderating role of openness. This study revealed the mechanism of the effect of subliminal stimuli on team trust, which lays an empirical foundation for individualized team trust improvement intervention. The current study provided novel insights that subliminal priming technology offers a new way to improve team trust.

Comparison of the effects of platelet-rich plasma and corticosteroid injection in rotator cuff disease treatment: a systematic review and meta-analysis.

HYPOTHESIS: Platelet-rich plasma (PRP) and corticosteroids are used to treat rotator cuff diseases. However, few reviews have compared the effects of these 2 treatments. In this study, we compared the effects of PRP and corticosteroid injection on the prognosis of rotator cuff diseases. MATERIALS AND METHODS: According to the Cochrane Manual of Systematic Review of Interventions, the PubMed, Embase, and Cochrane databases were searched comprehensively. Two independent authors screened suitable studies and performed data extraction and risk of bias assessment. Only randomized controlled trials comparing the effects of PRP and corticosteroid in the treatment of rotator cuff injuries were included, as measured by clinical function and pain during different follow-up periods. RESULTS: Nine studies with 469 patients were included in this review. In short-term treatment, corticosteroids were superior to PRP in the improvement of Constant, Simple Shoulder Test, and American Shoulder and Elbow Surgeons scores (mean difference [MD] -5.08, 95% confidence interval [CI] -10.26, 0.06; P = .05 and MD -0.97, 95% CI -1.68, -0.07; P = .03 and MD -6.67, 95% CI -12.85, -0.49; P = .03, respectively). No statistically significant difference was observed between the 2 groups at midterm (P > .05), and the recovery of the Simple Shoulder Test and American Shoulder and Elbow Surgeons scores in PRP treatment was significantly better than that in corticosteroid treatment in the long term (MD: 1.21, 95% CI: 0.68, 1.74; P < .00001 and MD: 6.96, 95% CI: 3.90, 9.61; P < .00001, respectively). In pain reduction based on visual analog scale score, corticosteroids led to better pain reduction (MD: 0.84, 95% CI: 0.03, 1.64; P = .04), but no significant difference was observed in pain reduction between the 2 groups in the any term (P > .05). However, these differences did not reach the minimum clinically important difference. CONCLUSIONS: Current analysis showed that corticosteroids have better efficacy in short term, whereas PRP is more beneficial for long-term recovery. However, no difference was observed in the mid-term efficacy between the 2 groups. Randomized controlled trials with longer follow-up periods and larger sample sizes are also needed to determine the optimal treatment.

The effect of subliminal priming on team trust: The mediating role of perceived trustworthiness.

The present study aimed to explore the effect of subliminal priming on team trust and the mechanism through the mediating role of perceived trustworthiness. A total of 144 participants were asked to complete a lexical decision task that was embedded with the "trust" or "suspicion" Chinese words as the subliminal stimuli. Then, they played a public good game and evaluated the perceived trustworthiness of the team. The results of the study showed that subliminal stimuli had a significant effect on team trust [ß = -0.99, 95% CI = (-1.64, -0.33)]. Perceived trustworthiness was found to have a significant mediating effect between the priming condition and team trust [ß = -0.35, 95% CI = (-0.72, -0.02)]. The current study revealed the underlying mechanism through which subliminal priming techniques influence team trust and informed efforts by altering perceived trustworthiness.

The impact of subliminal stimuli on interpersonal trust and team trust.

Although numerous studies related to trust have emerged in recent decades, few studies have explored the impact of subliminal stimuli on trust from an unconscious perspective. This study investigated (a) whether subliminal stimuli could influence interpersonal trust and team trust and (b) whether subjective trust played a mediating role between subliminal stimuli and behavioral trust. It contained two experiments. In Experiment 1, a total of 72 participants took part in a single factor design and completed five tasks. In Experiment 2, a total of 98 participants participated in a single factor design and completed five tasks. Results indicated that subliminal stimuli had a significant impact on interpersonal trust and team trust. Subjective trust played a mediating role between subliminal stimuli and behavioral trust. The results suggest that subliminal priming techniques can influence interpersonal trust and team trust. These techniques first influence subjective trust and then further influence behavioral trust.

Opioids for treating refractory dyspnea in patients with heart failure: A protocol for systematic review and meta-analysis.

BACKGROUND: Dyspnea is a hallmark symptom of heart failure. The existing clinical studies have indicated that opioid can effectively improve the clinical symptoms of heart failure patients with dyspnea. However, there has not been any relevant systematic review and meta-analysis. We performed a protocol for systematic review and meta-analysis to evaluate the safety and efficacy of opioid therapy for heart failure patients with refractory dyspnea. METHODS: We searched 3 foreign electronic databases (Cochrane Library, Embase, Pubmed) and 4 Chinese electronic databases (China National Knowledge Infrastructure, Wang Fang Database, Chinese Biomedical Literature Database and Chinese Scientific Journal Database) to collect potential studies from their inceptions to October 2022. The risk of bias in the included articles was assessed according to the Risk of Bias Assessment Tool in Cochrane Handbook of Systematic Reviews (5th edition). The quality of evidence was assessed by the Grading of Recommendations Assessment, Development and Evaluation approach. Data were analyzed using the RevMan Version 5.4.1. RESULTS: This study will evaluate whether opioid is effective and safe for treating refractory dyspnea in patients with heart failure. CONCLUSION: This meta-analysis will provide comprehensive evidence of opioid therapy for heart failure patients with dyspnea.

The experiences of caregivers of children with epilepsy: A meta-synthesis of qualitative research studies.

Objective: Epilepsy is one of the most common chronic neurological disorders in children. The caregivers of these children bear heavy burden of care in the process of taking care of them. The objective of this metasynthesis was to explore the experiences and needs of caregivers of children with epilepsy. Methods and data sources: Eight databases (PubMed, CINAHL, EMBASE, Web of Science, CNKI, Wanfang Data, VIP database, and CBM) were searched for qualitative studies from each database's inception to 31 June 2021. Studies were critically appraised using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Qualitative Research. Qualitative data were extracted, summarized, and meta-synthesized. Results: 13 studies were included, covering the data of 316 participants. 36 research results were extracted from these studies, which were combined into 11 categories, and finally formed 4 themes: (a) heavy burden of care; (b) emotional experience; (c) coping strategies; (d) care needs. Conclusion: Caregivers beared a heavy burden of care and psychological burden. Despite the adoption of different coping strategies, their emotional distress was still very serious. Caregivers had unmet care needs. In order to improve caregivers' care capacity, the society and healthcare workers need to provide them with information support, psychological support, and take measures to create a friendly medical and living environment for them. Impact: Understanding the experiences of caregivers of children with epilepsy will inform future research and practice. Healthcare workers could develop interventions to reduce caregiver burden and improve the level of caregivers' mental health. On the other hand, effective programs should be designed to improve caregivers' knowledge of the disease and enhance their ability to care. Society needs to take steps to improve the medical environment and the social stigma that is not friendly to epilepsy.

Association Between Passive Smoking and Menstrual Discomfort: A Cross-Sectional Study of 2,571 Non-smoking Chinese Nurses.

Introduction: Menstrual discomfort affects women's quality of life, which is an important public health issue. Evidence confirming the link between passive smoking and menstrual discomfort is limited. Therefore, the aim of this study is to investigate the aforementioned topic on the basis of a cross-sectional study of 2,571 non-smoking Chinese nurses. Methods: Demographic information and passive smoking were assessed using a self-administered questionnaire. Menstrual discomfort was characterized as dysmenorrhea, illness or weakness, bed rest, and restlessness during menstruation, which was assessed using a modified version of the Cornell Medical Index-Health Questionnaire. Multivariate-adjusted odds ratio (OR) and 95% confidence intervals (CIs) were estimated using the logistic regression model. Results: A total of 1:195 nurses (46.48%) were exposed to passive smoking. Compared with non-passive smoking nurses, passive smoking nurses were more likely to have menstrual discomfort symptoms (72.38 vs. 64.39%), especially symptoms of dysmenorrhea (49.54 vs. 42.08%), illnesses or weakness (48.28 vs. 42.08%), and restlessness during menstruation (53.05 vs. 46.22%). Exposure to passive smoking was significantly associated with menstrual discomfort (OR = 1.41, 95%CI: 1.19-1.67), especially symptoms of dysmenorrhea (OR = 1.32, 95%CI: 1.13-1.56), illness or weakness (OR = 1.24, 95%CI: 1.06-1.46), and restlessness (OR = 1.26, 95%CI: 1.08-1.48) during menstruation. The subgroup analyses, stratified by age, children, and marital status, agreed with the main findings. Conclusions: Exposure to passive smoking was related to symptoms of dysmenorrhea and menstrual discomfort.

Stress mindset and mental health status among Chinese high school students: The mediating role of exam stress appraisals.

Exam stress is one of the main stressors for adolescents, which can trigger severe mental health problems and performance decline. As an alterable individual variable that influences stress consequences, stress mindset has attracted academic attention recently. However, the relationship between stress mindset and adolescents' responses toward exams has not been fully understood. This study aimed to investigate whether stress mindset affected pre-exam mental health status and exam performance, and whether appraisals of exam mediated such influence. We collected stress mindset, threat and challenge appraisals, pre-exam mental health status, and exam scores from 185 Chinese 11th-grade students. All of them would take an important and unified exam organized on the school level. Results showed that the stress-is-enhancing mindset negatively predicted students' symptoms of depression, anxiety, and stress, but had no direct effect on performance. Further mediation analysis showed that stress-is-enhancing mindset was positively associated with the challenging appraisal and was negatively associated with the threat appraisal, thus having better health status (including fewer symptoms of depression, anxiety, and stress) and performance. These results suggest that the stress mindset had an association with students' response toward exams, and how they appraised the upcoming exam would be an important indirect pathway. Future studies may benefit from changing students' mindsets to protect them from negative consequences of exam stress.

Association Between Passive Smoking and Health Among Chinese Nurses: A Cross-Sectional Study.

This study aimed to investigate the association between passive smoking and physical and psychological health in Chinese nurses. Participants of this cross-sectional study comprised 2,484 non-smoking nurses. Passive smoking and demographic information were assessed using a self-administered questionnaire. Physical, psychological, and overall health status of nurses were measured using the Cornell Medical Index (CMI) health questionnaire. Multivariate-adjusted odds ratio (OR) and 95% confidence interval (CI) for nurses' health were estimated by exposure to passive smoking using unconditional logistic regression models. A total of 1,219 nurses (49.07%) were exposed to passive smoking. Of these, 609 (24.52%), 160 (6.44%), and 587 (23.63%) nurses had poorer physical, mental, and overall health, respectively. After adjusting for other confounding factors, compared with the non-passive smoking group, passive smoking was associated with poor physical (OR = 1.51, 95% CI: 1.25-1.83), mental (OR = 1.48, 95% CI: 1.07-2.07), and overall (OR = 1.58, 95% CI: 1.30-1.93) health of nurses, respectively. We also carried out subgroup analyses stratified by age, department, and professional title, which showed that most findings supported the main results. This study demonstrated that exposure to passive smoking was a risk factor for overall decreased physical and mental health status among Chinese nurses.

Effects of mindful breathing combined with sleep-inducing exercises in patients with insomnia.

BACKGROUND: Insomnia is the most common sleep disorder. It disrupts the patient's life and work, increases the risk of various health issues, and often requires long-term intervention. The financial burden and inconvenience of treatments discourage patients from complying with them, leading to chronic insomnia. AIM: To investigate the long-term home-practice effects of mindful breathing combined with a sleep-inducing exercise as adjunctive insomnia therapy. METHODS: A quasi-experimental design was used in the present work, in which the patients with insomnia were included and grouped based on hospital admission: 40 patients admitted between January and April 2020 were assigned to the control group, and 40 patients admitted between May and August 2020 were assigned to the treatment group. The control group received routine pharmacological and physical therapies, while the treatment group received instruction in mindful breathing and a sleep-inducing exercise in addition to the routine therapies. The Pittsburgh Sleep Quality Index (PSQI), Generalized Anxiety Disorder 7-item (GAD-7) scale, and Insomnia Severity Index (ISI) were utilized to assess sleep-quality improvement in the patient groups before the intervention and at 1 wk, 1 mo, and 3 mo postintervention. RESULTS: The PSQI, GAD-7, and ISI scores before the intervention and at 1 wk postintervention were not significantly different between the groups. However, compared with the control group, the treatment group exhibited significant improvements in sleep quality, daytime functioning, negative emotions, sleep latency, sleep duration, sleep efficiency, anxiety level, and insomnia severity at 1 and 3 mo postintervention (P < 0.05). The results showed that mindful breathing combined with the sleep-inducing exercise significantly improved the long-term effectiveness of insomnia treatment. At 3 mo, the PSQI scores for the treatment vs the control group were as follows: Sleep quality 0.98 ± 0.48 vs 1.60 ± 0.63, sleep latency 1.98 ± 0.53 vs 2.80 ± 0.41, sleep duration 1.53 ± 0.60 vs 2.70 ± 0.56, sleep efficiency 2.35 ± 0.58 vs 1.63 ± 0.49, sleep disturbance 1.68 ± 0.53 vs 2.35 ± 0.53, hypnotic medication 0.53 ± 0.64 vs 0.93 ± 0.80, and daytime dysfunction 1.43 ± 0.50 vs 2.48 ± 0.51 (all P < 0.05). The GAD-7 scores were 2.75 ± 1.50 vs 7.15 ± 2.28, and the ISI scores were 8.68 ± 2.26 vs 3.38 ± 1.76 for the treatment vs the control group, respectively (all P < 0.05). CONCLUSION: These simple, cost-effective, and easy-to-implement practices used in clinical or home settings could have profound significance for long-term insomnia treatment and merit wide adoption in clinical practice.

Males with low risk-taking propensity overestimate risk under acute psychological stress.

Arousing research has investigated stressed individuals' decision biases, but whether and how stress and individual traits interact to impact the underlying decision-making process is unknown. Here, we aim to explore the effect of acute stress on the interaction between the objective level of risk and subjective risk preference (i.e. risk-taking propensity). Eighty-three healthy males participated in the study. We adopted the Trier Social Stress Test (TSST) to induce acute psychological stress and categorized participants into the high or low risk-taking propensity (HRP/LRP) group according to their traits in daily life. The Balloon Analogue Risk Task (BART) was applied to measure their feedback processing in a risky decision task, while behavioral indexes and EEG signals were recorded. The results showed that stressful participants pumped fewer times than the controls, especially for the LRP under stress, indicating that they were more willing to avoid taking risks. Compared with the stressed HRP group, the stressed LRP showed higher salivary cortisol responses and a more positive FRN following positive feedback in higher risk levels. It implies that acute psychological stress leads the LRP to overestimate the risk probability and become more cautious in the sequential processing of risk. These findings highlight the role of the feedback process and individual traits in risky decision-making under stress.

Impact of spiritual care on the spiritual and mental health and quality of life of patients with advanced cancer.

BACKGROUND: Cancer is a growing threat to human health. Due to the double torment of cancer and cancer treatment, patients with advanced cancer generally have a low quality of life. At present, there is a lack of systematic spiritual care plans for patients with advanced cancer as well as systematic guidance plans on the specific clinical application of spiritual care for advanced cancer patients. We hypothesized that our care plan would be effective in improving the spiritual and mental health and quality of life of patients with advanced cancer. AIM: To construct a spiritual care plan suitable for Chinese patients with advanced cancer through literature analysis. METHODS: From February to December 2018, through purpose sampling, we selected 100 advanced cancer patients from the Oncology Department and Hospice Ward of a tertiary hospital in Liaoning Province who met the study standards. Patients were randomly divided into experimental and control groups, with 50 cases in each group. The control group received the current routine care, while the experimental group received the advanced cancer spiritual care intervention in addition to routine care. RESULTS: After the intervention, the overall spiritual health score for the experimental group was higher than that of the control group (4.68 ± 1.36 vs 3.63 ± 1.71). The difference between the groups was statistically significant (P < 0.05). The proportion of anxiety-free patients in the experimental group was 95.45%, which was significantly higher than the 60.98% in the control group. Moreover, the proportion of non-depressed patients in the experimental group was 97.73%, which was significantly higher than the 85.37% in the control group (P < 0.05). The overall quality of life score for the experimental group was significantly higher than that of the control group (5.36 ± 1.16 vs 4.39 ± 1.36, P < 0.05). CONCLUSION: Our spiritual care plan for patients with advanced cancer could improve their spiritual health and quality of life and reduce negative mental health symptoms.

Neural signature of affective but not cognitive self-regulation predicts cortisol response to psychosocial stress.

Self-regulation is theoretically closely related to coping with stressful events, yet whether self-regulation capacities can predict individual stress responses is largely unknown. Cognitive control and emotion regulation are two major aspects involved in self-regulation, both of which are mechanisms to support goal-directed behaviors. Here, we aimed to elucidate whether the neural processes involved in emotion regulation and cognitive control could predict the cortisol response to stress. Therefore, we recorded first electroencephalography (EEG) during a cognitive conflict task (Simon task) and an emotion regulation task (cognitive reappraisal and expressive suppression) before healthy participants (n = 72) underwent a psychosocial stressor. Our results showed that late positive potentials (LPPs) during the emotion regulation task predicted both cortisol reactivity to and recovery from stress. Cognitive control and its neural underpinning, however, did not predict the individual stress response. These findings indicate that neural emotion regulation processes can predict HPA axis response to stress, and suggest a differential involvement of cognitive and affective components of self-regulation in the adaptation to stressful events.

The psychological experiences of nurses after inpatient suicide: A meta-synthesis of qualitative research studies.

AIMS: To explore nurses' psychological experiences after inpatient suicide. DESIGN: Qualitative studies were meta-synthesized. DATA SOURCES: Eight databases (PubMed, Web of Science, CINAHL, Embase, Wanfang Data, VIP database, CBM and CNKI) were searched for qualitative studies from each database's inception to 31 August 2020. REVIEW METHODS: Studies were critically appraised using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Qualitative Research. Qualitative data were extracted, summarized, and meta-synthesized. RESULTS: Eleven studies were included, and five themes were identified: (a) emotional experience, (b) cognitive experience, (c) coping strategies, (d) self-reflection and (e) impact on self and practise. CONCLUSION: Nurses reported various negative emotions after inpatient suicide. Hospital administrators should recognize nurses' second victim psychological trauma. Moreover, they must develop theory-based education, training and psychological support programmes to promote nurses' mental health. Hospital patient safety management is also important to ensure patient safety whilst preventing nurses from becoming second victims. IMPACT: Understanding the psychological experiences of nurses who have undergone inpatient suicide will inform future research and practise. Nurses require psychological support after experiencing adverse events. Education and training are necessary to help nurses acquire suicide knowledge, understand the role of the second victim, better cope with adverse events and promote self-growth. Hospitals should strengthen the construction of a safety culture to ensure patient safety.

Effect of motivational interviewing on postoperative weight control in patients with obstructive sleep apnea-hypopnea syndrome.

BACKGROUND: Obesity is an important factor to cause the obstructive sleep apnea-hypopnea syndrome (OSAHS). Higher body mass index (BMI) often results in more severe OSAHS. Currently, the common measures for controlling the weight mainly include diet control, increase exercise and so on. Motivational interviewing (MI) could explore the patient's internal state and make the patient realize his/her ambivalence, resulting in the change in his/her behavior. This process emphasizes respecting the patient's autonomy. AIM: To evaluate the effect of MI on the weight control of patients with OSAHS. METHODS: A randomized controlled study was conducted in 100 obese OSAHS patients undergoing surgical treatment at Shengjing Hospital of China Medical University. The patients were divided into an intervention group and a control group, with 50 cases each. The control group was given routine health education after the operation; in addition to the regular health education, the intervention group was given MI according to a predetermined plan. Obesity-related indicators, postoperative complications, and the sleep status of both groups were evaluated before and 6 mo after the intervention. RESULTS: Patients in the intervention group had significantly improved body weight, BMI, and waist and neck circumferences compared with patients in the control group (P < 0.05). Regarding complications at 6 mo after operation, the incidence of cough and reflux in patients in the intervention group was significantly lower than that in the control group (P < 0.05). In addition, the Epworth Sleepiness Scale and Self-Rating Scale of Sleep scores of patients in the intervention group were significantly lower than those in the control group, and the sleep status of patients in the intervention group was improved (P < 0.05). CONCLUSION: MI intervention has a significant advantage over postoperative routine health education. It can greatly change the lifestyle, further control the postoperative weight, reduce the occurrence of complications, improve the quality of sleep, and improve long-term postoperative efficacy in OSAHS patients.

Lactoferrin-Loaded PEG/PLA Block Copolymer Targeted With Anti-Transferrin Receptor Antibodies for Alzheimer Disease.

Last few years, struggles have been reported to develop the nanovesicles for drug delivery via the brain-blood barrier (BBB). Novel drugs, for instance, iAß5, are efficient to inhibit the aggregates connected to the treatment of Alzheimer disease and are being evaluated, but most of the reports reflect some drawbacks of the drugs to reach the brain in preferred concentrations owing to the less BBB penetrability of the surface dimensions. In this report, we designed and developed a new approach to enhance the transport of drug via BBB, constructed with lactoferrin (Lf)-coated polyethylene glycol-polylactide nanoparticles (Lf-PPN) with superficial monoclonal antibody-functionalized antitransferrin receptor and anti-Aß to deliver the iAß5 hooked on the brain. The porcine brain capillary endothelial cells were utilized as BBB typically to examine the framework efficacy and toxicity. The cellular uptake of the immuno-nanoparticles with measured conveyance of the iAß5 peptide was significantly enhanced and associated with Lf-PPN without monoclonal antibody functionalizations.
