Background: Non-invasive prenatal testing (NIPT), also known as cell-free DNA testing and non-invasive prenatal screening (NIPS), is an important addition to the range of screening tests for fetal chromosomal abnormalities. For trisomy 21 in particular, NIPT is superior to other screening modalities. However, NIPT has limitations and complexities that requesting clinicians and their patients should understand.

Objective: This review article will briefly describe the technical basis of NIPT assays and compare the performance characteristics of NIPT with existing screening tests. The clinical use of NIPT will also be discussed.

Discussion: NIPT is now an established option for antenatal screening for trisomy 21, 18, 13 and other selected chromosomal abnormalities. If used appropriately, it increases the detection rate for fetal chromosomal abnormalities, while decreasing the number of invasive tests required. An understanding of the scientific basis of NIPT, and the appropriate clinical use and limitations, will enable medical practitioners to provide optimal antenatal screening.

Background: Practice-based research networks (PBRNs) are collaborations between clinical practitioners and academics. PBRNs aim to foster research in general practice through opportunities to learn more about how to undertake and participate in research, and assist in translating new knowledge into practice. Critically, PBRNs also offer clinicians the chance to contribute to research by posing questions of importance to quality clinical care.

Objective: The objectives of this article are to describe why PRBNs are needed, the current situation regarding PBRNs in Australia, and why Australian general practice and patient outcomes could benefit from further investment in PBRNs.

Discussion: PBRNs may assist by engaging more general practitioners (GPs) in the research process, thereby increasing the relevance of the research questions posed to the outcomes of the population GPs work within. Unlike similar countries (eg UK and The Netherlands), Australia no longer has any funding to support the activities of primary-care based PBRNs.

Background: Despite the general consensus that long-acting reversible contraceptives (LARCs) are the most appropriate choice of contraception for most women, there are special circumstances when the contraceptive and non-contraceptive needs of the patient are met by oral methods.

Objective: By using case histories, we seek to demonstrate the medical and practical complexities in managing contraceptive needs that may result in oral contraception being the most appropriate choice. The cases also illustrate the resources available to enable evidence-based management.

Discussion: Concurrent medical conditions and non-contraceptive benefits of oral contraceptive methods will see the continued use of these medications for a significant minority of women. A comprehensive knowledge of the rapidly developing evidence regarding medical eligibility and indications for usage is required. Reference to the already highly developed and easily accessible evidence bases ensures best practice for the women and families who seek advice.

Background: General practitioners (GPs) have a crucial role to play in engaging patients in discussions about overweight and obesity. However, such discussions are currently uncommon. The aim of this study was to examine how GPs in rural areas talk about overweight and obesity with their patients, specifically to identify key barriers to effective conversations.

Methods: This study used a qualitative methodology. Semi-structured interviews were conducted with GPs (n = 7) and patients (n = 7) across two rural areas.

Results: Key barriers to effective conversations between GPs and patients about overweight and/or obesity include: uncertainty about appropriate language; lack of time; concerns about compromising mutual trust and rapport; concerns about patient readiness; concerns about patients' mental health and how this may be impacted by discussing a potentially upsetting and stigmatising topic; and lack of effective and individualised treatment and/or referral options.

Discussion: The findings suggest that responses to overweight and obesity need to be localised and tailored. Structural-level change is required to enable better responses to overweight and obesity, including multidisciplinary team approaches.

Questions for this month's clinical challenge are based on articles in this issue. The clinical challenge is endorsed by the RACGP Quality Improvement and Continuing Professional Development (QI&CPD) program and has been allocated four Category 2 points (Activity ID: 109894). Answers to this clinical challenge are available immediately following successful completion online at http://gplearning.racgp.org.au. Clinical challenge quizzes may be completed at any time throughout the 2017-19 triennium; therefore, the previous months' answers are not published. Each of the questions or incomplete statements below is followed by four suggested answers or completions. Select the most appropriate statement as your answer.

Background: Erectile dysfunction is a common but often neglected condition. Prevalence increases with age, but is not insignificant in younger men.

Objective: This article will broadly describe the epidemiology, classification and risk factors of erectile dysfunction. It will also discuss assessment and current treatment modalities, with a particular focus on the unique role of the general practitioner (GP).

Discussion: Erectile dysfunction may be classified as vasculogenic, neurogenic, endocrinological, drug-related, psychogenic or mixed. Commonly, erectile dysfunction is a cause of anxiety and even depression. Risk factors, such as smoking and hypertension, and reversible causes, such as hypogonadism or offending medications, should be addressed. At present, oral pharmacotherapy represents the first-line option for most patients with erectile dysfunction. It is of utmost importance to evaluate and treat comorbidities, such as depression, metabolic syndrome and cardiovascular disease, that often accompany erectile dysfunction. Patients will undoubtedly benefit from comprehensive management by a dedicated GP. Occasionally, referral to a urologist, psychologist or sexual health physician may be required.

Background: Six per cent of patients who present to primary care have borderline personality disorder (BPD). Mothers with full or partial features of BPD, often undiagnosed and perhaps previously functioning adequately enough on the surface, may rapidly be-come emotionally dysregulated by the normal needs of an infant. Family and maternal functioning can rapidly destabilise. Management of patients with BPD in primary care may be challenging.

Objective: The objectives of this article are to provide primary care practitioners with relevant information on current knowledge of BPD and its management when mothers with BPD are caregivers to an infant.

Discussion: Useful guidelines for general practitioners that can help women who are emotionally dysregulated with infants include: keeping the diagnosis in mind openly discussing BPD diagnosis where relevant providing psychoeducational material and ongoing support to the woman and her familyreferring to specialised services for BPD referring to standard maternal-child health services and specialised .infant mental health services ongoing communication with other services and supervision for the practitioner.
