ABSTRACT

Given extensive pertinent disease factors and evolving medical treatments, this systematic review explores qualitative and quantitative cystic fibrosis (CF) research surrounding self-concept, an overarching perception of self. Research methodologies, self-concept dimensions, prominent self-concept findings and clinical recommendations are identified. Preferred Reporting Items for Systematic Review and Meta-analyses guidelines were applied. PubMed, Scopus, Medline, Psycinfo, CINAHL (ebsco), and CENTRAL Cochrane electronic databases were searched from 2012 to 2022. Methodological quality was assessed using the critical appraisal skills program. Data-based convergent synthesis was applied to analyze and report on qualitative and quantitative studies in parallel. Thirty-seven publications met the inclusion criteria, most of which employed a cross-sectional, single-center design within an adolescent and adult population. Self-efficacy, self-esteem, and self-identity studies were dimensions of self-concept identified, with studies relating to self-efficacy surrounding physical health management most prevalent. All three dimensions were positively associated with improved treatment adherence and psychosocial health. Efficacy tested intervention programs to enhance self-concept are limited; however, an extensive range of clinical recommendations are offered, highlighting the importance of clinician self-concept awareness, quality clinician-patient conversations and online CF peer-support. Self-concept is an important mechanism to optimize patient outcomes. Further CF self-concept research is required, particularly multicenter, longitudinal, and interventional studies. Early childhood, post lung transplant and the older adult CF population in particular, lack research attention. Given the potential impact of rapidly evolving CF transmembrane conductance regulator modulator drugs on many aspects of self, future self-concept research beyond the dimension of self-efficacy may be beneficial.

ABSTRACT

Recent European data facilitate an epidemiological investigation of the controversial cannabis-cancer relationship. Of particular concern were prior findings associating high-dose cannabis use with reproductive problems and potential genetic impacts. Cancer incidence data age-standardised to the world population was obtained from the European Cancer Information System 2000-2020 and many European national cancer registries. Drug use data were obtained from the European Monitoring Centre for Drugs and Drug Addiction. Alcohol and tobacco consumption was sourced from the WHO. Median household income was taken from the World bank. Cancer rates in high-cannabis-use countries were significantly higher than elsewhere (ß-estimate = 0.4165, p = 3.54 × 10-115). Eighteen of forty-one cancers (42,675 individual rates) were significantly associated with cannabis exposure at bivariate analysis. Twenty-five cancers were linked in inverse-probability-weighted multivariate models. Temporal lagging in panel models intensified these effects. In multivariable models, cannabis was a more powerful correlate of cancer incidence than tobacco or alcohol. Reproductive toxicity was evidenced by the involvement of testis, ovary, prostate and breast cancers and because some of the myeloid and lymphoid leukaemias implicated occur in childhood, indicating inherited intergenerational genotoxicity. Cannabis is a more important carcinogen than tobacco and alcohol and fulfills epidemiological qualitative and quantitative criteria for causality for 25/41 cancers. Reproductive and transgenerational effects are prominent. These findings confirm the clinical and epidemiological salience of cannabis as a major multigenerational community carcinogen.

ABSTRACT

Background: Anxiety disorders are highly prevalent and chronic disorders with treatment resistance to current pharmacotherapies occurring in approximately one in three patients. It has been postulated that flumazenil (FMZ) is efficacious in the management of anxiety disorders via the removal of α4ß2δ gamma-aminobutyric acid A receptors. Objective: To assess the safety and feasibility of continuous low-dose FMZ infusions for the management of generalised anxiety disorder (GAD) and collect preliminary efficacy data. Design: Uncontrolled, open-label pilot study. Method: Participants had a primary diagnosis of generalised anxiety disorder (GAD) and received two consecutive subcutaneous continuous low-dose FMZ infusions. Each infusion contained 16 mg of FMZ and was delivered over 96 ± 19.2 h. The total dose of FMZ delivered was 32 mg over approximately 8 days. Sodium valproate was given to participants at risk of seizure. The primary outcome was the change in stress and anxiety subscale scores on the Depression Anxiety Stress Scale-21 between baseline, day 8, and day 28. Results: Nine participants with a primary diagnosis of GAD were treated with subcutaneous continuous low-dose FMZ infusions; seven participants met the criteria for treatment resistance. There was a significant decrease in anxiety and stress between baseline and day 8 and baseline and day 28. There was also a significant improvement in subjective sleep quality from baseline to day 28 measured by the Jenkins Sleep Scale. No serious adverse events occurred. Conclusion: This study presents preliminary results for subcutaneous continuous low-dose FMZ's effectiveness and safety in GAD. The findings suggest that it is a safe, well-tolerated, and feasible treatment option in this group of patients. Future randomised control trials are needed in this field to determine the efficacy of this treatment.

ABSTRACT

OBJECTIVE: Test an intervention for individuals with schizophrenia at an Adult Inpatient Unit with employment and social inclusion goals, compared to treatment as usual. METHOD: A single-blind, randomised, controlled trial assigned 25 participants to treatment as usual and 26 participants to receive an Individual Placement and Support (IPS) Disability Employment Service (DES) information pack and an offer of support from a nurse. Outcomes were measured at 6 and 12 months using Job Acquisition, IPS DES employment provider, Activity Participation Questionnaire-Revised, Brief Psychiatric Rating Scale, and Adult Hope Scale questionnaires, and Digit Span and Trail Making tests. RESULTS: The intervention did not result in significant contact with the DES employment provider or paid employment outcomes. Secondary outcomes from combining groups due to high attrition rates: A significant proportion of participants obtained unpaid work from baseline to 6 months follow-up (N = 24, p = 0.001). CONCLUSIONS: The 'light touch' intervention did not promote change. More support is required during inpatient admissions and after discharge to assist people with schizophrenia achieve their vocational goals.

ABSTRACT

INTRODUCTION: Benzodiazepines (BZDs) are used in the management of anxiety and sleep disorders; however, chronic use is associated with tolerance and dependence. During withdrawal, symptoms of anxiety are often severe and problematic for patients and may lead to relapse or maintenance on low doses of BZDs. Low, continuous doses of flumazenil reduce BZD withdrawal symptoms in several studies; however, bolus doses are known to induce anxiety and precipitate panic. Accordingly, this study aimed to determine whether continuous low-dose flumazenil is anxiogenic like bolus doses. METHOD: In a randomised control cross over design, participants received a continuous low-dose flumazenil infusion for eight days at an approximate rate of 4 mg/24 h or placebo before crossing over to the alternate study arm. Participants were able to request diazepam as needed. The primary outcome was the change in state anxiety levels. Trait anxiety was also recorded at baseline and one month after the flumazenil/placebo infusion period. RESULTS: BZD use was significantly reduced in both groups. There were no significant differences between state anxiety and the 95% confidence interval showed no evidence of a clinically significant anxiogenic effect from low-dose flumazenil. Trait anxiety was significantly reduced one month after the infusion period. CONCLUSION: There is no evidence that continuous low-dose flumazenil infusion significantly increases state anxiety levels to a clinically significant level. Interestingly, flumazenil may decrease state anxiety during BZD withdrawal, unlike bolus doses of flumazenil. Flumazenil may have an anxiolytic effect on trait anxiety, which was evident one month after treatment.

ABSTRACT

OBJECTIVE: Test an intervention for people with schizophrenia and auditory verbal hallucinations at an acute inpatient unit (AIU) to engage with community therapy and reduce hallucination severity and associated distress. The trial cohort consisted of patients who after assessment by an AIU psychiatrist were not selected for an appointment with an AIU clinical psychologist and an opportunity for referral to a post-discharge community psychologist. An intervention providing the appointment and referral opportunity was compared to Treatment As Usual (TAU). METHOD: A single-blind, randomised, control trial compared the intervention with TAU over 6-months post-discharge using Engagement in Community Therapy, Psychotic Symptom Rating Scale (PSYRATS) auditory hallucinations and Revised Beliefs About Voices (BAVQ-R) questionnaires. RESULTS: Post-discharge community therapy engagement increased at 6 months compared to baseline in the intervention, TAU and combined groups. PSYRATS AHS and H-DIS scores decreased from baseline to last follow-up (statistically significant for TAU, and combined treatment groups). BAVQ-R RE scores decreased from baseline to last follow-up but the decrease was not statistically significant. CONCLUSIONS: Most participants chose to engage with a community therapist despite not being initially assigned for referral by their psychiatrist and experiencing moderately severe symptoms.

ABSTRACT

OBJECTIVE: Test whether extra time with alcohol and drug nurses for inpatients at a Mental Health Unit (MHU) reduces post-discharge mental and co-occurring alcohol and drug problems and increases engagement in alcohol and drug treatment more than a Brief Information Pack (BIP). METHOD: Single blind randomised control trial in block design compared two alcohol and drug nurse delivered interventions over 6 months post-discharge using the Alcohol Use Disorders Identification Test (AUDIT) and Brief Symptom Inventory index of overall psychological distress Global Severity Index (GSI). RESULTS: Alcohol and drug nurse delivered BIP was associated with a statistically significant reduction in AUDIT measured alcohol use for the highest follow-up score across the 6-month post-discharge period, n = 20, t = 2.24, p = 0.037, d = 0.50 and for the extra time intervention, n = 11, t = 2.51, p = 0.031, d = 0.76. CONCLUSIONS: MHUs may benefit from the integration of alcohol and drug nurses with community alcohol and drug treatment experience.

ABSTRACT

PURPOSE: This study explores the concept of social connectedness for adults with Cystic Fibrosis (CF), generally and during the onset of the COVID-19 pandemic, to help inform contemporary CF healthcare. Social connectedness is an essential component of belonging and refers to an individual's sense of closeness with the social world. Unique disease factors make exploration of social connectedness pertinent, added to by COVID-19, with the CF population potentially facing increased risk for severe illness. METHODS: Seventeen adults with CF in Western Australia undertook interviews, with findings categorized as overarching themes. RESULTS: In a general sense, participants described social connectedness challenges caused by CF, despite which they reported meaningful connections that benefits their mental and physical health. Within a COVID-19 specific context, participants demonstrated resilience in the face of adversity, highlighted the importance of empathy in relation to the pandemic, and described how social support is both an outcome and enhancer of social connectedness. CONCLUSIONS: This study contributes to limited social connectedness literature within CF and chronic illness in general, highlighting the importance of social connectedness awareness raising, assessments and interventions in CF healthcare inside and outside the COVID-19 pandemic.

ABSTRACT

OBJECTIVE: Fear of recurrence is common following treatment for cancer. Our aim was to assess the feasibility of mindfulness-based cognitive therapy (MBCT) to treat fear of cancer recurrence (FCR) in ovarian cancer survivors. METHODS: Investigator initiated, single-arm, open-label, pilot study. Women were eligible after completing adjuvant treatment. The intervention was an 8-week MBCT course of weekly 2-h group sessions. The primary outcome was FCR measured by the FCR inventory. Secondary outcomes were depression and anxiety measured by the Hospital Anxiety and Depression Scale (HADS). The study is registered with the Australian and New Zealand Clinical Trials Registry ACTRN12615000213549. RESULTS: Between May 8, 2015, and May 6, 2019, 33 participants were enrolled. Ten women withdrew. Data were evaluable for 19 participants. There was a significant decrease in FCR at 8 weeks (FCR inventory mean 63.00, SD 27.90) compared to pre-intervention (FCR inventory mean 71.03, SD 31.01) but not at 6 months (FCR inventory mean 63.65, SD 30.08). No differences in depression were observed at baseline (HADS mean 3.42, SD 2.41), 8 weeks (HADS mean 3.10, SD 1.79) and 6 months (HADS mean 2.73, SD 1.88). Anxiety decreased from baseline (HADS mean 8.72, SD 3.99) at both 8 weeks (HADS mean 6.89, SD 2.98) and 6 months (HADS mean 7.06, SD 3.87). CONCLUSIONS: MBCT may be effective as a treatment for FCR and anxiety in women following diagnosis and treatment of ovarian cancer. A randomised controlled trial is required to assess the efficacy of MBCT for FCR but may not be feasible due to high rates of withdrawal.

ABSTRACT

BACKGROUND: Psychotropic medication use occurs in 8% of pregnancies, with rates increasing, and often multiple medications prescribed. AIMS: This study aims to determine if the use of psychotropic medication, in a cohort of women with severe mental illness, increases rates of special care nursery admission and reports differences between antidepressant and antipsychotic medication use either alone or in combination. METHODS: A retrospective database analysis from a cohort with severe mental illness in pregnancy identified 268 pregnant women who were grouped according to medication type. Demographic, obstetric and neonatal variables were analysed using t-tests, χ2 , analysis of variance and logistic regression analysis for special care nursery admission. RESULTS: The medication groups consisted of: women taking no psychotropic medications (n = 67); those taking antipsychotics (n = 87); those taking antidepressants (n = 55); those taking and a combination of antidepressants/antipsychotics (n = 59). Rates of special care nursery admission in women who took psychotropic medication (41.3%) were elevated compared to those who did not (26.9%) (P = 0.035), and were significantly raised when compared to the general population (P < 0.000). No significant difference occurred between the medication groups. A significant adjusted odds ratio of 2.79 (95% CI 1.286-6.049) was found for special care nursery and psychiatric admission during pregnancy but not for psychotropic medication. CONCLUSION: Rates of special care nursery admission are elevated in neonates of women with severe mental illness taking psychotropic medication, but were not different for monotherapy or polytherapy when prescribing antidepressants or antipsychotic medication. Additional vulnerability occurs in the neonates of women with a mental illness and paediatric presence at delivery is recommended.

ABSTRACT

AIMS: The aim of this study was to explore and describe the experiences of persons attending a cancer support center, providing emotional support to cancer patients through self-selected complementary therapies offered free of charge through qualified volunteer therapists. A grounded theory methodology was used. Sources of data were 16 semistructured interviews with persons attending the center. Interviews were digitally recorded and transcribed verbatim. Analysis was conducted using the constant comparative method. FINDINGS: The overarching theme that emerged in this study was the benefits attributed to attendance at the cancer support center. The center was described as an "oasis" in the hospital, and three aspects relating to this were identified: (a) facilitating comfort, (b) increasing personal control, and (c) helping make sense of the cancer experience. CONCLUSION: A drop-in center offering complementary therapies appeared to enable coping with the diagnosis and treatment of cancer by facilitating comfort and increasing perceptions of personal control. The center also helped some participants to make sense of their experience with cancer. This research has provided a unique insight into the ongoing emotional needs of cancer patients, and directions for further development and research into the provision of holistic care for patients within a hospital setting.

ABSTRACT

Our group and others internationally have previously reported data on the use of low-dose flumazenil administered intravenously for the management of benzodiazepine withdrawal. This paper describes the first reported use of subcutaneous flumazenil infusion in the management of acute benzodiazepine withdrawal. Self-reported withdrawal symptoms and psychological state and anxiety sequelae were collected at baseline and then at intervals to 5 days following initiation of subcutaneous flumazenil infusion. Data indicate that patient subjective benzodiazepine withdrawal symptoms were well managed, with significant reduction in psychological distress seen over the duration of treatment. Perceived difficulty in performing everyday functions was positively correlated with withdrawal severity and improved over treatment. Patients reported high treatment comfort, willingness to undertake a future subsequent treatment using this technique, and willingness to recommend this treatment to a friend. This small proof-of-concept study indicates that subcutaneous flumazenil infusion has excellent tolerability, efficacy and improvement on measures of psychological distress. Given this technique is less invasive and requires fewer staff resources compared with intravenous administration, it may prove a significant asset in the management of benzodiazepine withdrawal.

ABSTRACT

This study investigated the influence of spirituality on depression in Western Australian women. Two hundred and seventy-eight women (aged 18-78) completed an online survey about factors relating to daily spiritual experience, depression, anxiety and social support. Significant correlations were found between spiritual experience and depression, whereby individuals who reported higher spirituality also reported higher rates of social support and lower levels of depression. A major finding from this study was that spirituality accounted for a significant proportion of variance in depressive symptoms beyond the mediating effect of social support.

ABSTRACT

PURPOSE OF REVIEW: In order to consider findings about the relationship between spirituality, religiosity and personality disorders, recent research was reviewed and emerging patterns in the latest findings were explored. RECENT FINDINGS: Within the diagnostic category of personality disorders, recent research into the role of spirituality has focused on schizotypy and borderline personality traits and aspects of 'control' relating to antisocial personality disorder. Although the number of studies is quite limited, this review has highlighted an interesting pattern emerging from recent studies that suggests that, while overall psychological well being has previously been reported as low, spiritual well being remains high in studies of personality focusing on schizotypy and borderline personality traits. SUMMARY: The positive link between religious and spiritual well being and mental health has been corroborated by a number of studies. This review of recent research has identified emerging trends suggesting that the dimensions of religious and spiritual well being remain high for individuals displaying schizotypy and borderline personality traits, and is not as reduced as general well being in individuals diagnosed with personality disorders. Although much work remains to be conducted with individuals diagnosed with personality disorders, spirituality appears to be an interesting area to explore clinically.

ABSTRACT

Previous research has demonstrated a link between attention-deficit/hyperactivity disorder (ADHD), developmental coordination disorder (DCD), and depression. The present study utilized a monozygotic (MZ) differences design to investigate differences in depressive symptomatology between MZ twins discordant for ADHD or DCD. This extends previous research as it controls for genetic effects and shared environmental influences and enables the investigation of nonshared environmental influences. In addition, children and adolescents with comorbid ADHD and DCD were compared on their level of depressive symptomatology to those with ADHD only, DCD only, and no ADHD or DCD. The parent-rated Strengths and Weaknesses of ADHD Symptoms and Normal Behavior, Developmental Coordination Disorder Questionnaire, and Sad Affect Scale were used to assess ADHD, DCD, and depressive symptomatology respectively. The results revealed higher levels of depressive symptomatology in MZ twins with ADHD or DCD compared to their nonaffected co-twins. In addition, children and adolescents with comorbid ADHD and DCD demonstrated higher levels of depressive symptomatology compared to those with ADHD only, DCD only, and no ADHD or DCD. The implications of these findings are discussed with emphasis on understanding and recognizing the relationship between ADHD, DCD, and depression in the assessment and intervention for children and adolescents with these disorders.

ABSTRACT

BACKGROUND: When symptom rating scales are used in the general population, there is severe skewness, with many individuals having no symptoms. While this has major implications for genetic designs that require extremely discordant and concordant (EDAC) siblings, little is known of the genetics of scales which seek to differentiate within the "no ADHD symptom" group. METHODS: Parents of Australian twins completed two attention-deficit/hyperactivity disorder (ADHD) questionnaires, the Australian Twin Behaviour Rating Scale (ATBRS), based on conventional DSM-IV symptom scores, and the Strengths and Weaknesses of ADHD-Symptoms and Normal-Behavior (SWAN) scale, which includes above-average performance on attention and activity. The two scales were compared in two age groups of same-sex twins, 528 pairs aged 6 to 9 and 488 pairs aged 12 to 20. RESULTS: Parents reported higher levels of activity and attention in their twins when reporting using the SWAN scale than when using the ATBRS, and while the monozygotic (MZ) correlations were similar on both scales, the dizygotic (DZ) correlations were consistently higher on the SWAN. On DSM-IV based scales, parents exaggerated differences within those sibling pairs in the "with few ADHD symptoms" category. CONCLUSIONS: The SWAN may provide a more realistic description of the ADHD phenotype for the selection of twin and sibling pairs for genetic analysis.

ABSTRACT

Attention-deficit hyperactivity disorder (ADHD) is a common childhood disorder which occurs more often in twins than singletons. This article focuses on the psychosocial consequences of having a co-twin with ADHD. Specifically, the level of anxiety (generalized and separation) in non-ADHD children who have a co-twin with ADHD is examined using data from the Australian Twin ADHD Project (ATAP). Parental report data on 501 dizygotic (DZ) twin pairs aged 6 to 15 and their siblings were used to examine (i) anxiety symptoms in twin pairs discordant for ADHD, (ii) how the effects of an ADHD twin on their co-twin and siblings are related to the type of ADHD, and (iii) whether the effects are greater for the nonaffected twin than nontwin siblings. Results show that anxiety was high in co-twins of children with the combined subtype of ADHD, with increased symptoms of both generalized and separation anxiety. Inattentive ADHD had smaller effects, which were confined to generalized anxiety and were specific to the co-twin rather than other siblings. These results have clinical implications in managing the entire multiple birth family where one twin has ADHD, and also has implications for genetic analysis in modeling the relationship of ADHD to internalizing disorders.

ABSTRACT

This article describes the Australian Twin Attention-deficit/hyperactivity disorder (ADHD) Project (ATAP), the results of research conducted using this database and plans for future studies. Information has been actively collected from Australian families with twin children since 1991 for the ATAP database. The value of assessing siblings as well as twins is emphasized. Much work has gone into continuing the involvement of families in the study though this does become more difficult when twins reach maturity. The main focus of the project is ADHD in children and adolescents plus comorbid conditions including conduct disorder, oppositional defiant disorder, and generalized anxiety disorder. A major challenge has been how to retain continuity in the assessments, while at the same time covering changes in psychiatric classification, such as the move to Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994). Changes in the scale can affect the reports of twin similarity. Over the years, these twins have become part of other twin studies and future plans include linking different twin databases to investigate the relationships between childhood behavior and adult conditions. Recruitment, assessment and retention of twin families require a major commitment but create a significant resource for collaboration in areas outside the original aim.
