Do beta-blockers reduce negative intrusive thoughts and anxiety in cancer survivors? - An emulated trial.

BACKGROUND: High rates of negative intrusive thoughts have been reported among cancer patients. Prevalent users of beta-blocker therapy have reported lower levels of cancer related intrusive thoughts than non-user. The aim of this study is to investigate if initiation of beta-blocker therapy reduces the prevalence and severity of intrusive thoughts (co-primary endpoints) and the prevalence of anxiety, depressed mood, and low quality of life (secondary endpoints) in cancer survivors. METHODS: Data on patient-reported outcomes from three cohort studies of Swedish patients diagnosed with colon, prostate or rectal cancer were combined with data on beta-blocker prescriptions retrieved from the Swedish Prescribed Drug Register. Two randomized controlled trials were emulated. Trial 1 had follow-up 1 year after diagnosis, trial 2 had follow-up 2 years after diagnosis, baseline in both trials was 12 months before follow-up. Those who initiated beta-blocker therapy between baseline and follow-up was assigned Active group, those who did not was assigned Control group. All endpoints were analysed using Bayesian ordered logistic regression. RESULTS: Trial 1 consisted of Active group, n = 59, and Control group, n = 3936. Trial 2 consisted of Active group, n = 87, and Control group, n = 3132. The majority of participants were men, 83% in trial 1 and 94% in trial 2. The prevalence and severity of intrusive thoughts were lower in the Active group in trial 1, but no significant differences between groups were found in either trial. The prevalence of depressed mood, worse quality of life and periods of anxiety were higher in the Active group in both trials with significant differences for quality of life in trial 1 and anxiety in trial 2. CONCLUSIONS: The emulated trials demonstrated no evidence of a protective effect of beta-blocker therapy against intrusive thoughts. The Active group had reduced quality of life and elevated anxiety compared to the Control group. TRIAL REGISTRATION: The three cohort studies were registered at isrctn.com/clinicaltrials.gov (ISRCTN06393679, NCT02530593 and NCT01477229).

Investigation of factors that may potentially affect anxiety in patients undergoing esophagogastroduodenoscopy and evaluation of sedation effect.

BACKGROUND: As with any other invasive procedure, esophagogastroduodenoscopy (EGD) may lead to considerable anxiety in patients. This study aimed to investigate and compare the effects of sedated and non-sedated procedures on anxiety in patients undergoing EGD and to better recognize patient groups at risk for anxiety. METHODS: In this prospective and 2-armed designed study, demographic data, including age, gender, comorbidities, height, weight, body mass index (BMI), and educational background, were collected. In this study, the Beck Anxiety Inventory (BAI) was administered to each patient before they were brought to the endoscopy unit. Subsequently, each patient who underwent EGD was telephoned on the seventh day after the procedure and the BAI was administered a second time. RESULTS: Women population had higher pre-EGD and post-EGD BAI scores compared to men. No significant correlation was observed between educational background and BAI scores. Possible correlations between age, BMI, Charlson comorbidity index (CCI), and BAI scores were examined. There was a weak correlation between BMI and pre-EGD and post-EGD BAI scores. A strong and positive correlation was observed between the pre-EGD BAI score and post-EGD BAI and difference in BAI scores between groups (ΔBAI). CONCLUSION: Endoscopic procedures may cause anxiety in patients as with all other invasive procedures. Patients' compliance with the procedure and having a lower level of anxiety are very significant for diagnostic and, if necessary, therapeutic success. In this study, the patient gender was evaluated as a predictor of anxiety level, whereas educational background was not a predictor.

Effectiveness and safety of Buzzy device in needle-related procedures for children under twelve years of age: A systematic review and meta-analysis.

BACKGROUND: Pain transcends simple physiology, encompassing biological, emotional, psychological, and social facets. Children show pronounced immediate and enduring responses to pain-related procedures. The aim of this meta-analysis is to investigate the efficacy and safety of the Buzzy device for needle-related procedures in children aged twelve years or younger. METHODS: PubMed, Web of Science, and Embase were searched from inception to July 2023. Only randomized controlled trials utilizing the Buzzy device for needle-related procedures in children under twelve years old were included. Two reviewers independently conducted study selection, data extraction, and risk of bias assessment. Random-effects models were utilized, and analyses were performed using mean differences or standardized mean differences as well as risk ratios. RESULTS: A total of 19 studies were included, involving 2846 participants (Buzzy = 1095, Control = 1751). Compared to no intervention, the Buzzy device significantly reduced pain response [self-report SMD = -1.90 (-2.45, -1.36), parental SMD = -3.04 (-4.09, -1.99), observer SMD = -2.88 (-3.75, -2.02)] and anxiety scores [self-report SMD = -1.97 (-3.05, -0.88), parental SMD = -2.01 (-2.93, -1.08), observer SMD = -1.92 (-2.64, -1.19)]. Compared to virtual reality (VR), the Buzzy device reduced self-reported anxiety levels SMD = -0.47 (-0.77, -0.17), and compared to distraction cards, the Buzzy device reduced parental and observer-reported pain [parental SMD = -0.85 (-1.22, -0.48), observer SMD = -0.70 (-1.00, -0.40)] and anxiety [parental SMD = -0.96 (-1.46, -0.47), observer SMD = -0.91 (-1.40, -0.42)]. Subgroup analysis results showed that procedure type, patient age, measurement scales used, and distance of operation were not the reason of heterogeneity. The summarized first puncture attempt success rate did not differ from other interventions. There were no significant adverse events in the included studies. CONCLUSION: The Buzzy device reduces pain and anxiety in children during needle procedures, ensuring success and safety. Additionally, the effectiveness of the Buzzy device in reducing pain during venipuncture is superior when compared to its effectiveness during intramuscular injections.

Virtual reality to reduce periprocedural anxiety during invasive coronary angiography: rationale and design of the VR InCard trial.

INTRODUCTION: Patients undergoing invasive coronary angiography (ICA) experience anxiety due to various reasons. Procedural anxiety can lead to physiological and psychological complications, compromising patient comfort and overall procedural outcomes. Benzodiazepines are commonly used to reduce periprocedural anxiety, although the effect is modest. Virtual reality (VR) is a promising non-pharmacological intervention to reduce anxiety in patients undergoing ICA. METHODS AND ANALYSIS: A single-centre open-label randomised controlled trial is conducted assessing the effectiveness of add-on VR therapy on anxiety in 100 patients undergoing ICA and experiencing anxiety in a periprocedural setting. The primary outcome is the Numeric Rating Scale (NRS) anxiety score measured just before obtaining arterial access. Secondary outcomes include postarterial puncture and postprocedural anxiety, patient-reported outcome measures (PROMs) of anxiety and physiological measurements associated with anxiety. The NRS anxiety level and physiological measurements are assessed five times during the procedure. The PROM State-Trait Anxiety Inventory and Perceived Stress Scale are completed preprocedure, and the PROM STAI and the Igroup Presence Questionnaire are performed postprocedure. ETHICS AND DISSEMINATION: The protocol of this study has been approved by the Research Ethics Committee of the Radboud University Medical Centre, the Netherlands (CMO Arnhem-Nijmegen, 2023-16586). Informed consent is obtained from all patients. The trial is conducted according to the principles of the Helsinki Declaration and in accordance with Dutch guidelines, regulations, and acts (Medical Research involving Human Subjects Act, WMO). REGISTRATION DETAILS: Trial registration number: NCT06215456.

Music Nursing as Complementary Therapy Improves Anxiety, Fatigue, and Quality of Life in Children with Acute Leukaemia: A Retrospective Study.

OBJECTIVE: To explore the effects of music nursing as a complementary therapy on anxiety, fatigue, and quality of life in children with acute leukemia (AL). METHODS: This study included 150 children with AL admitted to our hospital from August 2021 to August 2023 and divided them into two groups based on treatment: the control (n = 76, received routine nursing) and observation (n = 74, received music nursing on the basis of routine nursing) groups. Comparison of groups was performed in terms of general information, anxiety, fatigue, and quality of life at admission (T0) and 1 month after admission (T1). RESULTS: No significant differences were observed in the general data between the two groups (P > 0.05). Anxiety, fatigue, and quality of life of the two groups also showed no significant differences at T0 (P > 0.05). The observation group showed significantly lower anxiety than the control group at T1 (P < 0.05). At T1, the observation group exhibited a lower fatigue degree compared with the control group (P < 0.05). At T1, the observation group attained higher scores on physiological and emotional dimensions of the quality of life compared with the control group, and the differences were statistically significant (P < 0.05). CONCLUSION: Music nursing for AL children, which has a certain clinical application value, can effectively reduce their anxiety and fatigue and improve their quality of life.

Effectiveness of psychoeducational interventions on psychological distress and health-related quality of life among patients with maintenance hemodialysis: a systematic review and meta-analysis.

OBJECTIVE: To examine the effectiveness of psychoeducational interventions on depression, anxiety, and health-related quality of life (HRQOL) for people undergoing maintenance hemodialysis (MHD). METHODS: This review used systematic review and meta-analysis as the research design. Nine databases, including PubMed, Web of Science, Embase, CINAHL Complete, Cochrane Library, CNKI, WanFang, VIP, and Chinese Biomedical Literature Database, were searched from the inception to the 8th of July 2023. Two reviewers independently identified randomized controlled trials (RCT) examining the effects of psychoeducational interventions on MHD patients. RESULTS: Fourteen studies involving 1134 MHD patients were included in this review. The results of meta-analyses showed that psychoeducational intervention had significant short-term (< 1 m) (SMD: -0.87, 95% CI: -1.54 to -0.20, p = 0.01, I2 = 91%; 481 participants), and medium-term (1-3 m) (SMD: -0.29, 95% CI: -0.50 to -0.08, p = 0.01, I2 = 49%; 358 participants) on anxiety in MHD patients, but the effects could not be sustained at longer follow-ups. Psychoeducational interventions can also have short-term (< 1 m) (SMD: -0.65, 95% CI: -0.91 to -0.38, p < 0.00001, I2 = 65%; 711 participants) and medium-term (1-3 m) (SMD: -0.42, 95% CI: -0.76 to -0.09, p = 0.01, I2 = 69%; 489 participants) effects in reducing depression levels in MHD patients. Psychoeducational interventions that use coping strategies, goal setting, and relaxation techniques could enhance the QOL in MHD patients in the short term (< 1 m) (SMD: 0.86, 95% CI: 0.42 to 1.30, p = 0.02, I2 = 86%; 241 participants). CONCLUSIONS: Psychoeducational interventions have shown great potential to improve anxiety, depression, and quality of life in patients with MHD at the short- and medium-term follow-ups.Trial registration number: CRD42023440561.

Anxiety, depression, and stress: a comparative study between couples with male and female infertility.

BACKGROUND AND AIM: Although infertility as a significant cause of marital crises is prevalent almost equally in men and women, infertile women are under more pressure and distress than infertile men. Therefore, this study was conducted aiming to compare anxiety, depression, and stress between couples with male and female infertility. METHODS: In this descriptive-analytical cross-sectional study, 40 couples (n = 80) with male infertility and 40 couples (n = 80) with female infertility were referred to the infertility clinic of Al-Zahra Educational and Medical Center, Rasht, Iran. Eligible infertile couples were selected by convenience sampling method. The data collection tool was a two-part questionnaire consisting of a demographic information form and a short form of the standard Depression Anxiety Stress Scale-21 (DASS-21). Data analysis was carried out using descriptive and inferential statistical tests at a significant level of p < 0.05. RESULTS: The severity of depression, anxiety, and stress also had a statistically significant difference between men and women. The severity of depression was mild in 57.5% of infertile women and moderate in 40% of infertile men. The severity of anxiety was moderate in 42.5% of infertile women and mild in 57.5% of infertile men. The severity of stress was Severe in 37.5% of infertile women and mild in 40% of infertile men. There was a statistically significant difference between infertile women and men in terms of depression (t=-4.213, df = 1619, p < 0.001), anxiety (t=-7.261, df = 2274, p < 0.001), and stress (t=-9.046, df = 2308, p < 0.001) subscales, and the total scores (t=-7.709, df = 2315, p < 0.001). The depression, stress and anxiety levels were higher in infertile women than in healthy women with infertile spouses. This difference was statistically significant (p < 0.01). The depression, anxiety, and stress levels were significantly different between infertile men and healthy men with infertile wives (p < 0.001). CONCLUSION: The results of this study indicated that depression, anxiety, and stress were more prevalent in infertile women than in infertile men. The severity levels of depression, anxiety, and stress in the wives of infertile men were higher than those in the spouses of infertile women.

Effectiveness of WeChat-assisted preoperative education to reduce perioperative anxiety in breast cancer patients: a prospective randomized controlled study protocol.

BACKGROUND: Breast cancer is the most prevalent cancer among women globally, and surgical procedures continue to be the primary treatment. However, over 50% of patients experience preoperative anxiety due to the unknown and fear associated with surgery. Although drug therapy is commonly used to address this anxiety, its side effects have led to a heated debate regarding its effectiveness. Consequently, non-pharmacological therapies, such as preoperative education, have emerged as an alternative approach to alleviate anxiety. WeChat, a widely popular social media platform, offers a public platform that can potentially be utilized for effective preoperative education. This study aims to evaluate the use of WeChat public platform as a tool for preoperative education in patients undergoing breast surgery. METHODS: This is a prospective, randomized, and controlled trial will involve 392 adult women scheduled for breast cancer resection. Participants will be randomly assigned to either the WeChat education group or the regular group. In addition to regular preoperative visits, the WeChat education group will also watch science videos through the WeChat public platform. The regular group will only receive education from ward nurses during preoperative visits. The primary outcome measure will be the incidence of preoperative anxiety, defined by scores of the State Anxiety Inventory (SAI) exceeding 40 points. Secondary outcome measures include the incidence of severe anxiety (SAI > 44) on the day before surgery, incidence of anxiety 72 h after surgery, incidence of severe anxiety 72 h after surgery, NRS scores for pain at rest and during activity 24, 48, and 72 h after surgery, incidence of nausea and vomiting within 24 h after surgery, subjective sleep score at 1 week postoperatively, quality of life QoR-15 scores at 1 and 3 months postoperatively, incidence of chronic pain at 3 months postoperatively, bowel function recovery, length of hospital stay, and hospitalization expenses. DISCUSSION: This is the first clinical trial to investigate the use of WeChat public platform for delivering preoperative education on perioperative anxiety in breast cancer patients. By utilizing the renowned WeChat public platform, our study aims to improve patient outcomes by providing video education that explains the disease, surgery, and anesthesia in a more accessible manner, thereby reducing the incidence of perioperative anxiety. If our hypothesis is confirmed, this non-pharmacological approach can be universally acknowledged as a cost-effective and practical method in clinical care. Its application can also be extended to other medical fields beyond breast cancer. TRIAL REGISTRATION: ClinicalTrials.gov, NCT05291494. Registered on 29 December 2021.

Effect of quality nursing care on wound pain and anxiety in burn patients: A meta-analysis.

To systematically evaluate the effects of quality nursing care on wound pain and anxiety in burn patients. Computerised searches of PubMed, Google Scholar, Cochrane Library, Embase, Wanfang, China Biomedical Literature Database and China National Knowledge Infrastructure databases randomised controlled trials (RCTs) on the application of quality nursing care to burn patients were carried out from database inception to October 2023. Literature was screened and evaluated by two researchers based on inclusion and exclusion criteria, and data were extracted from the final included literature. Stata 17.0 software was employed for data analysis. Overall, 15 RCTs and 1115 burn patients were included, including 563 and 552 in the quality care and routine care groups. It was found that, compared with routine care, burn patients who implemented quality care had significantly less wound pain (SMD: -1.79, 95% CI: -2.22 to -1.36, p < 0.001), anxiety (SMD: -2.71. 95% CI: -3.49 to -1.92, p < 0.001) and depression (SMD: -1.74, 95% CI: -2.35 to -1.14, p < 0.001) levels were significantly reduced post-trauma.

Risk perception, well-being, depression and anxiety in children and adolescents with rheumatic diseases during the COVID-19 pandemic - results from the prospective multicenter KICK-COVID study in Germany.

OBJECTIVE: To investigate the psychosocial burden in children and adolescents with juvenile rheumatic diseases during the COVID-19 pandemic. METHODS: As part of the multicentre observational KICK-COVID study linked to the National Pediatric Rheumatology Database, adolescents < 21 years and parents of children < 12 years with rheumatic diseases answered questions on perceptions of health risk (PHR) due to SARS-CoV2, stress, well-being (WHO-5) and symptoms of depression (PHQ-9) and anxiety (GAD-7). Data were collected at routine visits from June to December 2021 and assessed for association with demographic and clinical parameters, treatment and patient-reported outcomes by multivariable regression analyses. RESULTS: Data from 1356 individuals (69% female, 50% adolescents) were included. Median PHR on a numeric rating scale (NRS, 0-10) was 4 (IQR 2-6), median perceived stress was 3 (IQR 1-6). Adolescents reported a worse well-being with a significantly lower median WHO-5-score (60, IQR 40-76) than parents reported for their children < 12 years (80, IQR 68-84). Moderate to severe symptoms of depression and anxiety were reported by 14.3% and 12.3% of the adolescents, respectively. PHR was significantly higher in patients with systemic lupus erythematosus, methotrexate or biologic disease-modifying anti-rheumatic drug therapy than in patients without these characteristics, whereas lower WHO-5 or higher PHQ-9 or GAD-7 scores were only associated with poorer patient-reported health status and physical functioning. CONCLUSION: The perception of health risk due to SARS-CoV2 infection was not paralleled by an impairment of mental health, which were, however, significantly correlated with self-rated health status and functional capacity, highlighting the importance of patient-reported outcome assessment.

Effects of comprehensive nursing interventions on wound pain in patients undergoing catheter insertion for peritoneal dialysis.

This study investigates the effects of comprehensive nursing interventions on wound pain in patients undergoing catheter insertion for peritoneal dialysis. Sixty patients who underwent catheter insertion for peritoneal dialysis from January 2021 to January 2023 at our hospital were selected as subjects and randomly divided into an experimental group and a control group using a random number table method. The control group received routine nursing care, while the experimental group was subjected to comprehensive nursing interventions. The study compared the impact of nursing measures on visual analogue scale (VAS), self-rating anxiety scale (SAS), self-rating depression scale (SDS) and nursing satisfaction between the two groups. The analysis revealed that on the third, fifth and seventh days post-intervention, the experimental group's wound VAS scores were significantly lower than those of the control group (p < 0.001). Furthermore, levels of anxiety and depression were markedly lower in the experimental group compared with the control group (p < 0.001). In addition, the nursing satisfaction rate was significantly higher in the experimental group than in the control group (96.67% vs. 73.33%, p = 0.011). This study indicates that the application of comprehensive nursing interventions in patients undergoing catheter insertion for peritoneal dialysis is highly effective. It can alleviate wound pain and negative emotions to a certain extent, while also achieving high patient satisfaction, thus demonstrating significant clinical value.

Exploring associations with depressive and anxiety symptoms among Syrian patients with ankylosing spondylitis undergoing biological treatment: A cross-sectional study.

People with ankylosing spondylitis (AS) are vulnerable group to experience mood disorders. It is crucial to identify factors that contribute to depression and anxiety in order to improve outcomes. This study seeks to determine the rates of depression and anxiety in Syrian AS patients, as well as identify potential predictors for these conditions. This cross-sectional study was conducted using convenience sampling at the Biological Treatment Unit of the Rheumatology Department of the Damascus Hospital. Data were collected from face-to-face interviews with patients using validated structural questionnaire. A multivariate linear regression model was used to investigate potential predictive factors of depressive and anxiety symptoms. Of the 103 patients, 49.5% showed clinically significant depressive symptoms, and 36.9 % showed clinically significant anxiety symptoms. Multivariate linear regression indicated that depressive and anxiety symptoms were predicted by job layoff, hip pain, positive history of mental distress, poor quality of life, severe fatigue, and high frequency of sleep disturbance with relatively high explanatory powers. depressive and anxiety symptoms were predicted by disease activity scores but with low explanatory power. This study demonstrated high levels of that depressive and anxiety symptoms among Syrian patients with AS undergoing biological treatment. Poor quality of life, severe fatigue, and high-frequency sleep disturbances are major predictive factors for depressive and anxiety symptoms. Screening for depression and anxiety holds significant importance in the comprehensive management of ankylosing spondylitis even in the context of concurrent biological treatment administration.

Effect of Operating Room Care Based on Wutong Mode on Anxiety and Depression of Patients Undergoing Abdominal Surgery: A Single-Center Retrospective Study.

BACKGROUND: The existence of anxiety and depression is not conducive to the rehabilitation of patients, so it is particularly important to apply reasonable and effective nursing methods in operating room to calm the negative emotions of patients. This study aimed to investigate the impact of operating room care utilizing the Wutong mode on the anxiety and depression levels of patients undergoing abdominal surgery.  Methods: The study included 167 patients who underwent abdominal surgery at our hospital from April 2021 to April 2023. These individuals were selected as the research subjects. Based on distinct perioperative management programs, the patients were categorized into the control group (comprising 85 patients receiving conventional perioperative management) and the study group (consisting of 82 patients undergoing operating room care based on the Wutong mode). Comprehensive baseline data, as well as scores from the Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI), Self-Rating Anxiety Scale (SAS), General Self-Efficacy Scale-6 (GSE-6), and Short-Form-36 Health Survey (SF-36), were collected from all participants. A comparative analysis was performed on sleep status, depression levels, anxiety levels, self-efficacy, and quality of life between the two groups.  Results: Following the intervention, the PSQI scores, as well as BDI and SAS scores of patients in both groups, were significantly reduced compared to pre-intervention levels (p < 0.001). Notably, the study group exhibited markedly lower PSQI scores, BDI scores, and SAS scores compared to the control group post-intervention (p < 0.001). Additionally, the GSE-6 scores of patients in both groups showed a substantial increase after the intervention compared to pre-intervention levels (p < 0.001). The study group demonstrated significantly higher GSE-6 scores and SF-36 scores than the control group after the intervention (p < 0.001).  Conclusion: The Wutong mode-based operating room care has a pronounced impact on patients undergoing abdominal surgery, demonstrating clear clinical application value. This finding offers valuable insights for the development and selection of perioperative nursing plans for patients, providing a significant reference point for healthcare practitioners.

Additive anxiolytic-like effect of citicoline and ACPA in the non-acute restraint stress (NARS) and acute restraint stress (ARS) mice.

The cannabinoid system plays a key role in stress-related emotional symptoms such as anxiety. Citicoline is a supplemental substance with neuroprotective properties that alleviates anxiety-related behaviors. There is a relation between the actions of cannabinoids and cholinergic systems. So, we decided to evaluate the effects of intracerebroventricular (i.c.v.) infusion of cannabinoid CB1 receptor agents on citicoline-produced response to anxiety-like behaviors in the non-acute restraint stress (NARS) and acute restraint stress (ARS) mice. For i.c.v. microinjection of drugs, a guide cannula was inserted in the left lateral ventricle. ARS was induced by movement restraint for 4 h. Anxiety-related behaviors were assessed using an elevated plus maze (EPM). The results showed that induction of ARS for 4 h decreased the percentage of time spent in the open arms (%OAT) and the percentage of entries to the open arms (%OAE) without affecting locomotor activity, showing anxiogenic-like behaviors. i.c.v. infusion of ACPA (1 µg/mouse) induced an anxiolytic-like effect due to the enhancement of %OAT in the NARS and ARS mice. Nonetheless, i.c.v. microinjection of AM251 (1 µg/mouse) decreased %OAT in the NARS and ARS mice which suggested an anxiogenic-like response. Intraperitoneal (i.p.) administration of citicoline (80 mg/kg) induced an anxiolytic-like effect by the augmentation of %OAT in the ARS mice. Furthermore, when ACPA and citicoline were co-administrated, ACPA potentiated the anxiolytic-like effect induced by citicoline in the NARS and ARS mice. On the other hand, when AM251 and the citicoline were co-injected, AM251 reversed the anxiolytic-like response induced by the citicoline in the NARS and ARS mice. The results of this research exhibited an additive effect between citicoline and ACPA on the induction of anxiolytic-like response in the NARS and ARS mice. Our results indicated an interaction between citicoline and cannabinoid CB1 receptor drugs on the control of anxiety-like behaviors in the NARS and ARS mice.

Nitric Oxide (NO) Synthase Inhibitors: Potential Candidates for the Treatment of Anxiety Disorders?

Close to 19% of the world population suffers from anxiety. Current medications for this chronic mental disorder have improved treatment over the last half century or more, but the newer anxiolytics have proved disappointing, and enormous challenges remain. Nitric oxide (NO), an intra- and inter-cellular messenger in the brain, is involved in the pathogenesis of anxiety. In particular, excessive NO production might contribute to its pathology. This implies that it might be useful to reduce nitrergic activity; therefore, molecules aiming to downregulate NO production such as NO synthase inhibitors (NOSIs) might be candidates. Here, it was intended to critically review advances in research on these emerging molecules for the treatment of anxiety disorders. Current assessment indicates that, although NOSIs are implicated in anxiety, their potential anti-anxiety action remains to be established.

The effectiveness of therapeutic artmaking on depression, anxiety, quality of life, and psychological distress in cancer patients on chemotherapy: a systematic review of the literature.

OBJECTIVES: The purpose of this study was to evaluate the evidence of art therapy on depression, anxiety, quality of life, and mental distress in cancer patients undergoing chemotherapy. METHODS: A systematic literature search was conducted. A systematic search of online electronic databases including, PubMed/MEDLINE, Scopus Web of Science, PsycINFO, and EMBASE was performed using keywords extracted from Medical Subject Headings such as "Art Therapy," and "Neoplasms," "Cancer," and "Chemotherapy" from the earliest to January 11, 2023. A total of 3890 publications were assessed for relevance by title and abstract. The remaining 1298 articles were examined using three inclusion criteria: interventions were guided by an artist or art therapist, participants were actively involved in the creative process, and anxiety, depression, and/or quality of life were included as outcome measures. The methodological quality of the included studies was appraised using specific checklists. RESULT: A total of 495 patients with cancer undergoing chemotherapy participated in ten studies. Among the participants, 87.21% were female and 63.43% of them were in the intervention group. The mean age of the participants was 53.93 in five studies that reduced depression in cancer patients undergoing chemotherapy. Six studies investigated the effect of different art therapy methods on the anxiety of patients, which in four studies reduced their anxiety. Also, three studies investigated the effect of different art therapy methods on patients' distress, which in two studies reduced their distress. CONCLUSION: Art therapy had positive effects on depression, anxiety, quality of life, and psychological distress of cancer patients undergoing chemotherapy. Meanwhile, research on art therapy in cancer patients on chemotherapy is insufficient. We cannot conclude that art therapy benefits cancer patients on chemotherapy. More rigorous research is needed.

Global prevalence of major depressive disorder, generalized anxiety, stress, and depression among infertile women: a systematic review and meta-analysis.

BACKGROUND: In recent years, the global prevalence of infertility has increased among women (Talmor and Dunphy, Best Pract Res Clin Obstet Gynaecol 29(4):498-506, 2015) and is considered as a public health concern. One of the impacts of infertility is mental health problems in the patients, which can lead to complications such as stress, anxiety, and depression. The aim of this study is to investigate the global prevalence of major depressive disorder, general anxiety, stress, and depression in infertile women through a systematic review and meta-analysis. METHODS: To identify studies that have reported the prevalence of major depressive disorder, generalized anxiety, stress, and depression in infertile women, the PubMed, Scopus, Web of Science, Embase, ScienceDirect, and Google Scholar repositories were systematically searched. Articles published up until February 2023 were included, while no lower time limit was imposed in the search strategy. Heterogeneity of studies was examined using the I2 test and, thus, random-effects model was used to perform the analysis. Data analysis was conducted within the Comprehensive Meta-Analysis (v.2) software. RESULTS: In the review of 44 studies with a sample size of 53,300 infertile female patients, the overall prevalence of major depressive disorder (clinical depression), generalized anxiety, stress, and depression was found to be 22.9%, 13.3%, 78.8%, and 31.6% respectively. It was also found that mental health complications are more prevalent among infertile women in Asia (continent). CONCLUSION: Considering the prevalence of mental disorders among infertile women, health policymakers can use the results of the present meta-analysis to pay more attention to the mental health of infertile women and devise suitable interventions and programs to reduce and prevent the spread of psychological disorders among infertile women.
