Development of a non-infectious control for viral hemorrhagic fever PCR assays.

Assay validation is an essential component of disease surveillance testing, but can be problematic in settings where access to positive control material is limited and a safety risk for handlers. Here we describe a single non-infectious synthetic control that can help develop and validate the PCR based detection of the viral causes of Crimean-Congo hemorrhagic fever, Ebola virus disease, Lassa fever, Marburg virus disease and Rift Valley fever. We designed non-infectious synthetic DNA oligonucleotide sequences incorporating primer binding sites suitable for five assays, and a T7 promotor site which was used to transcribe the sequence.

VEGF-A related SNPs: a cardiovascular context.

Cardiovascular diseases (CVDs) are the leading cause of death worldwide. Currently, cardiovascular disease risk algorithms play a role in primary prevention. However, this is complicated by a lack of powerfully predictive biomarkers that could be observed in individuals before the onset of overt symptoms.

Feasibility and acceptability of telehealth and contactless delivery of human papillomavirus (HPV) self-testing for cervical screening with Māori and Pacific women in a COVID-19 outbreak in Aotearoa New Zealand.

Aim: To determine the feasibility and acceptability of a telehealth offer and contactless delivery of human papillomavirus (HPV) cervical screening self-test during the 2021 COVID-19 Level 4 lockdown in Auckland, New Zealand.

Methods: A small proof-of-concept study was undertaken to test telehealth approaches in never-screened, due or overdue Māori and Pacific women enrolled in a local Primary Health Organisation (PHO). Study invitation, active follow-up, nurse-led discussions, result notification and a post-test questionnaire were all delivered through telehealth.

Human papillomavirus self-testing among unscreened and under-screened Māori, Pasifika and Asian women in Aotearoa New Zealand: A preference survey among responders and interviews with clinical-trial nonresponders.

Introduction: Māori, Pasifika and Asian women are less likely to attend cervical screening and Māori and Pasifika women are more likely to be diagnosed with later-stage cervical cancer than other women in Aotearoa New Zealand. This study-with under-screened women taking part in a randomized-controlled trial comparing self-testing and standard screening-explored the acceptability of a human papillomavirus (HPV) self-test kit and the preferred method for receiving it.

Methods: Māori, Pasifika and Asian women (N= 376) completed a cross-sectional postal questionnaire.

Human Papillomavirus (HPV) Self-Sampling among Never-and Under-Screened Indigenous Māori, Pacific and Asian Women in Aotearoa New Zealand: A Feasibility Study.

In Aotearoa, New Zealand, the majority of cervical cancer cases occur in women who have never been screened or are under-screened. Wāhine Māori, Pacific and Asian women have the lowest rate of cervical screening. Self-sampling for human papillomavirus (HPV-SS) has been shown to increase participation in cervical cancer screening.

Acceptability of human papillomavirus (HPV) self-sampling among never- and under-screened Indigenous and other minority women: a randomised three-arm community trial in Aotearoa New Zealand.

Background: Internationally, self-sampling for human papillomavirus (HPV) has been shown to increase participation in cervical-cancer screening. In Aotearoa New Zealand, there are long-standing ethnic inequalities in cervical-cancer screening, incidence, and mortality, particularly for indigenous Māori women, as well as Pacific and Asian women.

Methods: We invited never- and markedly under-screened (≥5 years overdue) 30-69-year-old Māori, Pacific, and Asian women to participate in an open-label, three-arm, community-based, randomised controlled trial, with a nested sub-study.

Correction to: Comparison of two invitation-based methods for human papillomavirus (HPV) self-sampling with usual care among un- and under-screened Māori, Pacific and Asian women: study protocol for a randomised controlled community trial to examine the effect of self-sampling on participation in cervical-cancer screening.

Comparison of two invitation-based methods for human papillomavirus (HPV) self-sampling with usual care among un- and under-screened Māori, Pacific and Asian women: study protocol for a randomised controlled community trial to examine the effect of self-sampling on participation in cervical-cancer screening.

Background: Māori, Pacific and Asian women in New Zealand have lower cervical-cancer screening rates than European women, and there are persistent inequities in cervical cancer outcomes for Māori and Pacific women. Innovative ways to address access barriers are required. New Zealand is transitioning to screening with human papillomavirus (HPV) DNA testing, which could allow women themselves, rather than a clinician, to take the sample.

Acceptability of human papillomavirus self-sampling for cervical-cancer screening in under-screened Māori and Pasifika women: a pilot study.

Aim: To assess whether self-sampling for cervical-cancer screening is acceptable to New Zealand women.

Methods: Māori, Pacific and Asian un- or under-screened women aged 30-69 years were asked to: 1) examine three self-sampling devices; 2) complete a questionnaire on demographics and experiences with the devices; and 3) take a self-sample. Samples were tested 'off-label' using the cobas® 4800 human papillomavirus (HPV) test (Roche Diagnostics NZ).

A survey of knowledge, attitudes and awareness of the human papillomavirus among healthcare professionals across the UK.

Background: Human papillomavirus (HPV) is a common sexually transmitted infection implicated in 5% of cancers worldwide including most cervical cancer cases. In the UK, the HPV vaccine has been offered routinely to girls aged 11-13 since 2008 while cervical screening is offered to women aged 25-64. HPV testing will soon replace cytology as the primary screening method.

Knowledge, attitudes and awareness of the human papillomavirus among health professionals in New Zealand.

Background: Human papillomavirus (HPV) is a common sexually transmitted infection that is implicated in 99.7% of cervical cancers and several other cancers that affect both men and women. Despite the role that HPV plays in an estimated 5% of all cancers and the evolving role of HPV vaccination and testing in protecting the public against these cancers, preliminary research in New Zealand health professionals suggest knowledge about HPV may not be sufficient.

Healthcare-seeking behaviour of people with sexually transmitted infection symptoms attending a Sexual Health Clinic in New Zealand.

Aims: Untreated sexually transmitted infections (STIs) can lead to serious health complications and may be transmitted to uninfected individuals. Therefore, the early detection and subsequent management of STIs is crucial to control efforts. Time to presentation for STI symptoms and risk of transmission in this period has not been assessed in New Zealand to date.

What influences university students to seek sexually transmitted infection testing?: A qualitative study in New Zealand.

Objective: Untreated sexually transmitted infections (STIs) can lead to serious health complications, increase susceptibility to contracting further STIs including human immunodefiniceny virus (HIV), and can be transmitted to others. The early diagnosis and treatment of STIs is therefore central to comprehensive STI management and prevention, but this relies on those at risk of STIs presenting for testing. In order to understand STI testing behaviours in view of their improvement, this study aimed to elucidate why people seek STI testing.

Barriers to sexually transmitted infection testing in New Zealand: a qualitative study.

Objective: To investigate the barriers that prevent or delay people seeking a sexually transmitted infection (STI) test.

Methods: Qualitative in-depth interviews were conducted with 24 university students, who are a group prone to behaviours putting them at risk of STIs, to understand the factors that had prevented or delayed them from going for an STI test in the past. Resulting data were thematically analysed employing a qualitative content analysis method, and a final set of themes identified.

Using iron studies to predict HFE mutations in New Zealand: implications for laboratory testing.

Background: The diagnosis of hereditary haemochromatosis (HH) is not straightforward because symptoms are often absent or non-specific. Biochemical markers of iron-overloading may be affected by other conditions.

Aim: To measure the correlation between iron studies and HFE genotype to inform evidence-based recommendations for laboratory testing in New Zealand.

Heterozygous mutations in cause juvenile peroxisomal D-bifunctional protein deficiency.

Objective: To determine the genetic cause of slowly progressive cerebellar ataxia, sensorineural deafness, and hypergonadotropic hypogonadism in 5 patients from 3 different families.

Methods: The patients comprised 2 sib pairs and 1 sporadic patient. Clinical assessment included history, physical examination, and brain MRI.

The incidence of sexually acquired reactive arthritis: a systematic literature review.

Reactive arthritis (ReA) is an inflammatory spondyloarthritis occurring after infection at a distant site. Chlamydia trachomatis is proposed to be the most common cause of ReA, yet the incidence of sexually acquired ReA (SARA) has not been well established. We therefore carried out a systematic literature review to collate and critically evaluate the published evidence regarding the incidence of SARA.

Complete callosal agenesis, pontocerebellar hypoplasia, and axonal neuropathy due to AMPD2 loss.

Objective: To determine the molecular basis of a severe neurologic disorder in a large consanguineous family with complete agenesis of the corpus callosum (ACC), pontocerebellar hypoplasia (PCH), and peripheral axonal neuropathy.

Methods: Assessment included clinical evaluation, neuroimaging, and nerve conduction studies (NCSs). Linkage analysis used genotypes from 7 family members, and the exome of 3 affected siblings was sequenced.

Pre-vaccination type-specific HPV prevalence in confirmed cervical high grade lesions in the Māori and non-Māori populations in New Zealand.

Background: New Zealand initiated HPV vaccination in 2008, and has attained 3-dose coverage of ~50 % in 12-13 year old girls. Due to the success of program initiatives in Māori girls, higher coverage rates of ~60 % have been achieved in this group. We have previously reported a benchmark overall pre-vaccination prevalence of oncogenic HPV infection in high grade cervical lesions in New Zealand.

Lymphogranuloma venereum in men who have sex with men: evidence of local transmission in New Zealand.

Lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by Chlamydia trachomatis. Five laboratory confirmed cases of LGV were detected in MSM (men who have sex with men) in the upper North Island; four in Auckland between September and December 2013 and a fifth case was detected in Waikato in June 2014. The absence of a recent travel history for four cases supports the likelihood of local transmission of this uncommon infection.

Mutations in RAB39B cause X-linked intellectual disability and early-onset Parkinson disease with α-synuclein pathology.

Advances in understanding the etiology of Parkinson disease have been driven by the identification of causative mutations in families. Genetic analysis of an Australian family with three males displaying clinical features of early-onset parkinsonism and intellectual disability identified a ∼45 kb deletion resulting in the complete loss of RAB39B. We subsequently identified a missense mutation (c.
