First nations people's perspectives on barriers and supports for enhancing HPV vaccination: Foundations for sustainable, community-driven strategies

OBJECTIVE

In Canada, Indigenous people have higher human papillomavirus (HPV) infection rates, lower screening rates for cervical cancer, and higher rates of invasive cancer, leading to worse cervical cancer-related outcomes than observed in non-Indigenous Canadian women. Lingering harms from European colonization drive these health inequities and create public health challenges. Policy guidance is needed to optimize HPV vaccination rates and, thereby, decrease the burden of HPV-related illness, including high-morbidity surgical procedures and chemo-radiotherapy. The Enhancing HPV Vaccination In First Nations Populations in Alberta (EHVINA) project focuses on First Nations, a diverse subset of recognized Indigenous people in Canada, and seeks to increase HPV vaccination among girls and boys living in First Nation communities.

METHODS

Developing an effective strategy requires partnership with affected communities to better understand knowledge and perceptions about cancer, healthcare, and the HPV vaccine. A 2017 community gathering was convened to engage First Nations community members, health directors, and health services researchers in dialogue around unique barriers and supports to HPV vaccination in Alberta. Voices of community Elders, parents, health directors, and cancer survivors (n=24) are presented as qualitative evidence to help inform intervention design.

RESULTS

Key findings from discussions indicate barriers to HPV vaccination include resource constraints and service infrastructure gaps, historical mistrust in healthcare systems, impacts of changing modes of communication, and community sensitivities regarding sexual health promotion. Supports were identified as strengthened inter-generational relationships in communities.

CONCLUSIONS AND FUTURE DIRECTION

Ongoing dialogue and co-development of community-based strategies to increase HPV vaccine uptake are required. The identification of possible barriers to HPV vaccination in a Canadian Indigenous population contributes to limited global literature on this subject and may inform researchers and policy makers who work with Indigenous populations in other regions.

Controlling food, controlling relationships: exploring the meanings and dynamics of family food practices through the diary-interview approach

Potential merits of a social practice perspective for examining the meanings and dynamics of family food include moving beyond individual behaviour, and exploring how practices emerge, develop and change. However, researchers have struggled to encourage reflection on mundane practices, and how to understand associated meanings. Drawing on a study of families in South Wales, this article reflects on the value of the diary-interview approach in addressing these methodological challenges, and aims to explore and understand the dynamics of control across family contexts. Contemporary practice theories distinguish between practices as 'performances' and practices as 'entities' and the diary-interview method facilitated an examination of these dimensions. Detailed accounts of daily 'performances' (through diaries), alongside reflection on underlying contexts and 'entities' (through interviews), illustrated the entanglement of control, practices and context. The article adds further complexity to the concept of practice 'bundles' which facilitated an understanding of how food was interrelated with other practices - across family contexts and across generations. Sociological approaches with a practices perspective at the core, offer potential for developing public health interventions by acknowledging: the relational meaning of food; the embeddedness of food within everyday practices; and the need to consider interventions across a range of policy areas.

Developments in mycotoxin analysis: an update for 2016-2017

This review summarises developments in the determination of mycotoxins over a period between mid-2016 and mid-2017. Analytical methods to determine aflatoxins, Alternaria toxins, ergot alkaloids, fumonisins, ochratoxins, patulin, trichothecenes and zearalenone are covered in individual sections. Advances in proper sampling strategies are discussed in a dedicated section, as are methods used to analyse botanicals and spices and newly developed LC-MS based multi-mycotoxin methods. This critical review aims to briefly discuss the most important recent developments and trends in mycotoxin determination as well as to address limitations of the presented methodologies.

The public's knowledge of psychiatrists: questionnaire survey

Aims and Method

One objective of the Royal College of Psychiatrists' stigma campaign is to improve the public's knowledge about psychiatric illness. There has been little work in the UK on the public's knowledge of the training of psychiatrists and the treatments they use. Using a questionnaire, we compared a sample representing the general population (n=223) with a sample attending psychiatric outpatients (n=67) to assess their level of knowledge.

Results

Half of the general population sample did not know that psychiatrists were medically qualified, and 80% underestimated the length of psychiatric training. There was variable knowledge of the conditions treated by psychiatrists and treatment methods used, with the outpatient group having better knowledge of drug treatments.

CLINICAL IMPLICATION

If the general public do not know about the training and expertise of psychiatrists, this is likely to limit their willingness to seek treatment for mental illness.

Cardiac output changes with phenylephrine and ephedrine infusions during spinal anesthesia for cesarean section: A randomized, double-blind trial

Hypotension is a common side effect of spinal anesthesia. Phenylephrine and ephedrine are the two most frequently used vasopressors to treat spinal hypotension during cesarean delivery. In this randomized double-blind study, we aimed to evaluate cardiac output (CO) changes with phenylephrine or ephedrine infusions titrated to maintain baseline systolic blood pressure (bSBP) during spinal anesthesia. Women (n = 40) scheduled for elective cesarean delivery received either phenylephrine 100 μg/min or ephedrine 5 mg/min infusions. Baseline hemodynamics (cardiac output, heart rate, systolic blood pressure) were recorded in the left lateral tilt position before fluid preload, and recorded every minute after spinal anesthesia until delivery. Umbilical cord blood gases were analyzed within 5 minutes of delivery. Good systolic blood pressure control was attained in both groups with minimal periods of hypotension (SBP <80% of bSBP) or hypertension (SBP >120% of bSBP). Cardiac output and heart rate increased over time with ephedrine, but decreased with phenylephrine. The maximum increase in CO from the baseline was 12%, in the ephedrine group, and this occurred 20 minutes after spinal injection. Cardiac output fell by more than 17% in the phenylephrine group, maximal at 10 minutes following spinal injection. Despite good systolic blood pressure control and increased cardiac output with ephedrine, administration of ephedrine was associated with significantly more fetal acidosis [Median (Interquartile range, IQR) UApH - phenylephrine = 7.33 (7.31-7.34) and ephedrine = 7.22 (7.16-7.27), P < .05].

Effect of pulmonary exacerbations treated with oral antibiotics on clinical outcomes in cystic fibrosis

BACKGROUND

Despite extensive knowledge regarding the effect of pulmonary exacerbations treated with intravenous antibiotics on clinical outcomes in cystic fibrosis (CF), there is little known about the role of milder pulmonary exacerbations treated with oral antibiotics (oPEx).

METHODS

This was a retrospective cohort study of patients with CF followed at the Hospital for Sick Children and St. Michael's Hospital from 2009 to 2014. We evaluated the effect of oPEx on short-term clinical outcomes as the proportion of oPEx events in which 100% or 90% of baseline FEV₁% predicted was recovered at the end of treatment. We then examined the association of the number of oPEx events in the past 12 months on lung function (FEV₁% predicted) and nutritional status (body mass index (BMI) z-score) using a mixed-effects model.

RESULTS

There were a total of 2608 oPEx events in 570 subjects during the study period. In over half (53.4%) of oPEx events, lung function was already at 90% or higher of baseline FEV₁ at the initiation of oral antibiotic therapy and 82% were at 90% or higher of baseline FEV₁ at follow-up. In individuals with CF, one or more oPex events in the previous 12 months were associated with decreased FEV₁ compared with 12 months periods without oPex events. When the cumulative effect of oPExs on lung function was examined over the entire study period, patients with six or more oPEx events had the steepest rate of FEV₁ decline. oPEx events were not associated with changes in BMI.

CONCLUSIONS

oPEx events are associated with short-term loss of FEV₁ and have a negative effect on lung function over time.
