title: The Neolithic of Vietnam

authors: Piper, Philip J.

subjects: Vietnam

abstract: The Neolithic in Mainland Southeast Asia is considered to be the period of human prehistory that commenced with the transition from hunting and gathering into mixed economies of foraging and farming. It lasted until the appearance of copper and bronze metallurgy and thus dates between circa 2500 and 1200 BC. In Vietnam, Neolithic sites and cultures are recorded especially around the edges of the Red River delta, along the northern and central coasts, and in the southern river basins between the Đông Nai and lower Mekong. This period of Vietnamese prehistory was characterized by the southward movements of East Asian Neolithic populations from southern China across Mainland Southeast Asia, the introduction of cereal cultivation (rice and foxtail millet), and the management of domesticated pigs and dogs. The Neolithic of Vietnam also reveals material culture relationships extending from southern China to central Thailand. Recent research is also starting to highlight social and cultural diversity during this period, together with the development of significant exchange networks.

title: Gender differences in depression and anxiety symptoms eight years after mild traumatic brain injury

authors: Leidig, Rebecca Dawn

abstract: The majority of all treated cases of traumatic brain injury are classified as being in the mild severity range (MTBI) but many symptoms are far from mild and can result in difficulties that persist for years after the initial injury, severely affecting quality of life.  Chronic depression and anxiety symptoms can be masked by acute post-concussion symptoms and can affect males and females differently in the long-term but little research has been undertaken in this area.  The aims of this study were to investigate the gender differences in depression and anxiety over 1-month, 12-months and 8-years following a mild traumatic brain injury and to investigate gender differences in depression and anxiety between a group of MTBI subjects (8-years post-injury), and a group of participants who were TBI-free, by comparing Hospital Anxiety and Depression Scale (HADS) scores and self-reported symptoms.  A MTBI cohort consisting of a population-based sample of 151 adults who sustained a mild TBI between 2010 and 2011 was identified from an earlier longitudinal study: Brain Injury Incidence and Outcomes New Zealand In the Community Study (BIONIC).  Additionally, 213 participants with no history of head injury were recruited for comparison.  Both groups answered questions about current anxiety and depression symptoms using the HADS.
Overall, results suggest that males and females with MTBI have the same overall course of recovery in relation to depression and anxiety symptoms over the 8-years following injury but that females consistently report significantly increased symptoms than males over time, as reflected in the general population.  Depression and anxiety scores fluctuate over the 8-years post-MTBI but, overall, depression increases, anxiety decreases and symptom levels are below clinical severity.  Females with MTBI are significantly more likely than males to experience anxiety in the clinical range at 12-months post-injury.  
There were no significant gender differences in depression or anxiety levels between the MTBI and comparison groups, and average HADS scores were not significantly different between groups.  However,  individual symptom analysis showed that females who were 8-years post-MTBI experienced increased panic symptoms than females with no TBI and that both males and females with MTBI reported increased anhedonia and “restlessness’ symptoms than those without MTBI.   Overall, females reported significantly higher severity symptoms related to nervousness and feeling slowed down than males.
The clinical implications of this study suggest a focus on the longer-term impacts of MTBI  as patients may experience later onset depression or anxiety that may not be present in the acute phase.  Evaluating individual symptoms as well as overall scores on measures can identify important clinical effects at symptom level that are masked by total score analysis.    
Practitioners should consider gender differences in how patients respond to self-report symptom measures to ensure accurate clinical assessment of both males and females, particularly in relation to MTBI which has a higher male prevalence.  Future research into MTBI outcomes that includes a broader range of measures, in addition to self-report, will ensure comprehensive clinical data is obtained about individual symptoms and risk factors. 
This study uniquely contributes to current research into gender outcomes post-MTBI and may guide clinical practice to develop effective, timely and targeted assessment and treatment interventions for depression and anxiety symptoms experienced by both males and females after mild traumatic brain injury.

title: Reconnecting whānau: Pathways to recovery for Māori with bipolar disorder

authors: Waitoki, Waikaremoana

subjects: mental health

abstract: While Māori are known to experience a higher burden of mental health and addiction problems compared to non-Māori (Baxter, 2008), little exploratory research has been conducted into Māori experiences of bipolar affective disorder. Bipolar disorder is at times regarded as a “life sentence”, with little hope of recovery. The recovery- focused mental health literature, however, argues wellness is achievable for even the most intractable conditions (Lapsley, Nikora, & Black, 2002; Mental Health Commission, 2001). The aim of this research was to gather information about the experiences of Māori who were diagnosed with bipolar affective disorder. Interviews were conducted with 22 Māori wāhine (women) and tāne (men), and using thematic analyses, themes relevant to their life stories were uncovered. This research sought to contribute to the realisation of Māori potential by explicitly shifting from deficit- focused frameworks to a focus on systemic factors that influenced Māori wellbeing. Highlights were that whānau (participants) who were connected with friends, partners and family were motivated to achieve wellness and to stay well.
