Supporting caregivers of children with developmental disabilities: Findings from a brief caregiver well-being programme in South Africa.

LAY ABSTRACT: Young children with developmental disabilities and delays who live in low- and middle-income countries are at significant risk of not reaching their full potential. We know that daily interactions with their caregivers (parents or other people taking care of them) play an important role in promoting their development. However, having a child with developmental disabilities can have a negative impact on carers' mental health and well-being, which in turn can influence their capacity to care for their children. To date, very little attention has been given to the caregivers' capacity to care. The World Health Organization developed a Caregiver Skills Training programme which includes a brief, three-session module that focuses on improving caregivers' well-being and mental health. This well-being programme is based on acceptance and commitment therapy. Acceptance and commitment therapy shows increasing evidence of helping people respond to their stressors, thoughts, feelings and experiences a little differently and commit to small changes that are in line with their personal values. Acceptance and commitment therapy has shown promise in improving feelings of well-being in caregivers of children with developmental disabilities. We adapted the World Health Organization Caregiver Skills Training Caregiver well-being module to suit the South African context. The resultant 'Well Beans for Caregivers' was then delivered to caregivers from a rural, low-resource setting in South Africa. We found the intervention easy to implement, highly acceptable to caregivers and showed promising impacts on caregivers' well-being and mental health. This intervention has the potential to be implemented widely and sustainably to build caregivers' capacity to care for their children.

Childhood emotional neglect and oxytocin receptor variants: Association with limbic brain volumes.

Objectives: Childhood emotional neglect (EN) is a predictor for the development of affective disorders. Oxytocin (OXT) may mediate the interplay between EN and changes in stress biological systems, brain development, and mental health outcomes. We investigated, in a cross-sectional study, the associations between EN, (epi)genetic variation in the OXT receptor (OXTR) gene, and amygdalar and hippocampal volumes, two brain regions implicated in emotional processing.Methods: We recruited 63 Caucasian South African adults (35 women) with and without social anxiety disorder. Childhood EN was assessed using the Childhood Trauma Questionnaire. rs53576 and rs2254298 genotypes, as well as methylation status, was determined using DNA purified from whole blood. Bilateral amygdalar and hippocampal volumes were determined by structural magnetic resonance imaging. The relationships between these variables were investigated using linear regression.Results: The interaction of the rs2254298 A risk allele and EN was nominally associated with reduced left hippocampal volume. The rs2254298 A risk allele was independently associated with reduced bilateral amygdalar volumes. We found no association between EN, OXTR methylation and amygdalar or hippocampal volumes. The rs53576 GG risk genotype was, however, associated with decreased OXTR methylation.Conclusions: The rs2254298 A allele may increase susceptibility to the structural brain effects of EN.

Posttraumatic stress disorder, social anxiety disorder and childhood trauma: Differences in hippocampal subfield volume.

Volume-based hippocampal findings in Social Anxiety Disorder (SAD) and Posttraumatic Stress Disorder (PTSD) have been inconsistent, with very little investigation of hippocampal subfields. We assessed the effects of early childhood trauma on hippocampal subfields in participants with SAD with and without early childhood trauma and PTSD, compared to healthy controls. The sample comprised 26 participants SAD with early childhood trauma, 22 participants with SAD without early childhood trauma, 17 with PTSD secondary to early childhood trauma and 25 control participants. We used Freesurfer version 6 to determine hippocampal subfield volumes. Findings included significant reduction in right parasubiculum volume between the PTSD group secondary to early childhood trauma and the SAD group without early childhood trauma, as well as a significant reduction in left HATA (Hippocampal Amygdala Transition Area) volume between PTSD with early childhood trauma compared to controls, as well as compared to SAD with early childhood trauma. These findings did withstand correction for multiple resting using the false discovery rate. Our findings of an association of reduced volumes in the parasubiculum and HATA regions with PTSD secondary to childhood trauma are interesting. Further work should investigate whether parasubiculum and HATA regional volume reductions in PTSD are a specific effect of early childhood trauma or a specific manifestation of PTSD pathology. Further work should also be undertaken to determine if hippocampal subfield atrophy is associated with SAD in the setting of early childhood maltreatment.

An Examination of Differences in Psychological Resilience between Social Anxiety Disorder and Posttraumatic Stress Disorder in the Context of Early Childhood Trauma.

Background: Much of the research on anxiety disorders has focused on associated risk factors with less attention paid to factors such as resilience that may mitigate risk or offer protection in the face of psychopathology. Objective: This study sought to compare resilience in individuals with posttraumatic stress disorder (PTSD) and social anxiety disorder (SAD) relative to age-, gender- and education- matched individuals with no psychiatric disorder. We further assessed the correlation of resilience scores with childhood trauma severity and type. Method: The sample comprised of 93 participants, 40 with SAD with childhood trauma), 22 with PTSD with childhood trauma, and 31 with no psychiatric disorder (i.e., healthy matched controls). Participants were administered the Mini-International Neuropsychiatric Interview (MINI), Liebowitz Social Anxiety Scale (LSAS), Clinician-Administered PTSD Scale (CAPS), Childhood Trauma Questionnaire-Short Form (CTQ-SF), and the Connor-Davidson Resilience Scale (CD-RISC). The mean age of participants was 34 years (SD = 11). 52 Participants were female (55.9%) and 54 Caucasian (58.1%). Analysis of variance was used to assess for significant group differences in resilience scores. Non-parametric correlation analyses were conducted for resilience and different types of childhood trauma. Results: There were significant differences in resilience between the SAD and PTSD groups with childhood trauma, and controls. Both disorder groups had significantly lower levels of resilience than healthy controls. No significant correlation was found between total resilience scores and childhood trauma scores in the childhood trauma (SAD and PTSD) groups. However, in the combined dataset (SAD, PTSD, healthy controls), significant negative correlations were found between resilience scores and emotional abuse, emotional neglect, and total childhood trauma scores. Conclusions: Patients who have PTSD and SAD with childhood trauma appear to be significantly less resilient than those with no disorder. Assessing and addressing resilience in these disorders, particularly when childhood trauma is present, may facilitate long-term recovery and warrants further investigation.

An analysis of early developmental trauma in social anxiety disorder and posttraumatic stress disorder.

BACKGROUND: The early contributions of childhood trauma (emotional, physical, sexual, and general) have been hypothesized to play a significant role in the development of anxiety disorders, such as posttraumatic stress disorder (PTSD) and social anxiety disorder (SAD). The aim of this study was to assess childhood trauma differences between PTSD and SAD patients and healthy controls, as measured by the Early Trauma Inventory. METHODS: We examined individuals (N = 109) with SAD with moderate/severe early developmental trauma (EDT) (n = 32), individuals with SAD with low/no EDT (n = 29), individuals with PTSD with EDT (n = 17), and healthy controls (n = 31). The mean age was 34 years (SD = 11). Subjects were screened with the Mini-International Neuropsychiatric Interview (MINI), Liebowitz Social Anxiety Scale (LSAS), Clinician-Administered PTSD Scale (CAPS), and Childhood Trauma Questionnaire (CTQ). Analysis of variance was performed to assess group differences. Correlations were calculated between childhood traumas. RESULTS: Although not statistically significant, individuals with PTSD endorsed more physical and sexual childhood trauma compared with individuals with SAD with moderate/severe EDT who endorsed more emotional trauma. For all groups, physical and emotional abuse occurred between ages 6 and 11, while the occurrence of sexual abuse in individuals with PTSD was at 6-11 years and later (13-18 years) in individuals with SAD with moderate/severe EDT. For emotional abuse in all groups, the perpetrator was mostly a primary female caregiver; for sexual abuse, it was mostly a nonfamilial adult male, while for physical abuse, it was mostly a caregiver (male in PTSD and female in SAD with moderate/severe EDT). CONCLUSIONS: The contribution of childhood abuse to the development of PTSD and SAD and the differences between these groups and other anxiety disorders should not be ignored and attention should be given to the frequency and severity of these events. The relationship of the perpetrator(s) and the age of onset of childhood abuse are also important considerations as they provide a useful starting point to assess impact over the life course. This can, in turn, guide clinicians on the optimal timing for the delivery of interventions for the prevention of PTSD and SAD.

Child and adolescent cognitive behaviour therapy in South Africa: An editorial review.

The evidence base for cognitive behaviour therapy (CBT) (1) and other psychotherapeutic interventions in child and adolescent populations in low to middle income countries such as in South Africa is almost non-existent. In this review we explored the transportability of cognitive behaviour therapy interventions into the South African mental health care environment. Further investigations of CBT's effectiveness for children and adolescents and its cultural adaptability in South Africa are needed. (1)When using 'cognitive behaviour therapy' in this article we refer to all iterations and therapies that support the basic principles of CBT and that are evidenced based.

Alterations in HbA1c following minimal or enhanced non-surgical, non-antibiotic treatment of gingivitis or mild periodontitis in type 2 diabetic patients: a pilot trial.

AIM: The purpose of this pilot study was to determine and compare the effects of two protocols aimed at reducing periodontal inflammation, upon the metabolic control of the diabetic condition in subjects with elevated baseline glycosylated hemoglobin (HbA1c). METHODS AND MATERIALS: Forty-two non-smoking type 2 diabetes subjects with mildly elevated HbA1c (>7 but < 9%) and severely elevated (>9%) were randomized to one of two non-surgical periodontal therapy protocols. Patients in the "minimal therapy" (MT) group received scaling, root planning, and oral hygiene instructions on two occasions six months apart. Participants randomized to the "frequent therapy" (FT) protocol received scaling, root planing, and oral hygiene instructions at two-month intervals and were provided a 0.12% chlorhexidine rinse for home use twice daily. Neither systemic nor local antibiotics were provided to either group. Subjects were asked to report any changes in diabetic medications, nutrition, and physical activity. Data analyses (ANOVA, t-test, Mann-Whitney) grouped subjects according to baseline HbA1c (>7 and < 9%, or > 9%), treatment protocol (minimal or frequent), and +/- medication change. RESULTS: In both MT and FT groups the clinical attachment level (CAL) remained unchanged but the other measures [gingival index (GI) and pocket dept (PD)] of periodontal health improved. Mean reductions in plaque showed improvement but calculus was worse in the FT group, likely due to the use of chlorhexidine. At six months, the largest reduction of HbA1c was 3.7; experienced by a subject receiving FT but no changes in diabetic medication. Among the MT and no medication change subjects, the maximum reduction was 1.6. Overall mean reduction in HbA1c of 27 subjects with baseline HbA1c >9.0 and no medication change was 0.6 with no statistical difference between the MT and FT groups. Among the medication-change subjects with baseline HbA1c >9.0, mean reduction of 1.38 was seen with FT compared to 1.10 with MT. CONCLUSION: Overall, modest improvements in HbA1c were detected with a trend towards FT being better than MT. Although this pilot trial was under-powered to detect small between-group differences, the magnitude of our findings (0.6 mean improvement in HbA1c) matches closely findings from the only meta-analysis conducted on this topic to date. Larger scale studies must be undertaken on diabetic patients with periodontal problems. CLINICAL SIGNIFICANCE: Preventive periodontal regimens for diabetic patients should be sufficiently intense and sustained to eliminate periodontal inflammation and should be closely coordinated with the patient's overall clinical diabetic management.

Oral health and HIV.

Most oral health problems can be found in people who are either HIV positive or negative. Yet there are some important differences. A few conditions are seen almost exclusively in people with HIV, while some that are found in both populations are more problematic for people with HIV, especially those with advanced disease. A diminished immune system can alter the course of oral disease and require more aggressive treatment to prevent minor troubles from escalating into major health problems. Over 30 different oral manifestations of HIV disease have been reported since the beginning of the AIDS epidemic. This article will address several of the most common of these oral health issues. As with any health condition faced by HIV positive people, early identification and treatment should be emphasized. In many cases, referral to a dentist should be made as soon as possible.

Impact of intensified dental care on outcomes in human immunodeficiency virus infection.

This study evaluated the health effects of routine and intensified dental care and disease prevention in persons with human immunodeficiency virus (HIV). We recruited 376 HIV-infected persons ages 19 to 61 with CD4 counts between 100 and 750 into a year-long two-arm randomized controlled trial. Control group subjects (n = 185) received professional dental protective treatment and checkups at baseline, 6 months, and 1 year, plus dental care. Enhanced care patients (n = 191) received bimonthly protective treatment and twice-daily chlorhexidine mouthrinses to treat gingivitis. Active decay, gingivitis, oral pain, impact of oral health on functioning, and global functional status improved in both groups. The mean depth of periodontal pockets decreased 0.18 mm (control group) versus 0.27 mm (enhanced group) (p < 0.04), as did an erythema index (-1.22 versus -1.78, p < 0.01). No effects on acquired immune deficiency syndrome (AIDS)-related complications, symptoms, or mortality were observed. We concluded that access to dental screening, prophylaxis, and repair will significantly improve oral health, functioning, and quality of life in persons with AIDS.
