Women's experiences of safety apps for sexualized violence: a narrative scoping review.

BACKGROUND: Sexualized violence against women is a significant human rights problem worldwide. Safety apps have the capacity to provide women with resources to prevent or respond to experiences of sexualized violence. METHODS: The aim of the following study was to review the scope of the literature on women's experiences of safety apps related to sexualized violence. The databases Embase, MEDLINE, PsycINFO, and Scopus were systematically searched, and seven studies were included in this review. RESULTS: Thematic analysis identified the following themes in the literature: (1) security; (2) accessibility; and (3) knowledge. CONCLUSION: The gaps in the literature are identified and implications and recommendations for future research is discussed.

A rapid review of Indigenous boys' and men's sexual health in Canada.

Indigenous boys and men in Canada face adverse social and structural circumstances that affect their ability to achieve and maintain sexual health. Research about Indigenous sexual health, however, is largely limited to matters relating to women and statistics on sexually transmitted infections. A rapid review of research was conducted to determine what is currently known about Indigenous boys' and men's sexual health in Canada. Given the prevalence of research documenting quantitative disparities, the current review included qualitative research only. Thirteen included studies explored a wide range of topics relating to sexual health and an overarching intersection between social conditions and individual health outcomes was observed. The results of this review reveal significant gaps in the literature relating to the holistic sexual health of Indigenous boys and men and highlight important domains of sexual health to consider in future research. Findings suggest that sexual health programmes that promote traditional Indigenous knowledge and intergenerational relationships may be effective for promoting sexual health among Indigenous boys and men.

NOX2-Derived Reactive Oxygen Species Control Inflammation during Leishmania amazonensis Infection by Mediating Infection-Induced Neutrophil Apoptosis.

Reactive oxygen species (ROS) produced by NADPH phagocyte oxidase isoform (NOX2) are critical for the elimination of intracellular pathogens in many infections. Despite their importance, the role of ROS following infection with the eukaryotic pathogen Leishmania has not been fully elucidated. We addressed the role of ROS in C57BL/6 mice following intradermal infection with Leishmania amazonensis. Despite equivalent parasite loads compared with wild-type (WT) mice, mice deficient in ROS production by NOX2 due to the absence of the gp91 subunit (gp91phox-/-) had significantly more severe pathology in the later stages of infection. Pathology in gp91phox-/- mice was not associated with alterations in CD4+ T cell-mediated immunity but was preceded by enhanced neutrophil accumulation at the dermal infection site. Ex vivo analysis of infected versus uninfected neutrophils revealed a deficiency in infection-driven apoptosis in gp91phox-/- mice versus WT mice. gp91phox-/- mice presented with higher percentages of healthy or necrotic neutrophils but lower percentages of apoptotic neutrophils at early and chronic time points. In vitro infection of gp91phox-/- versus WT neutrophils also revealed reduced apoptosis and CD95 expression but increased necrosis in infected cells at 10 h postinfection. Provision of exogenous ROS in the form of H2O2 reversed the necrotic phenotype and restored CD95 expression on infected gp91phox-/- neutrophils. Although ROS production is typically viewed as a proinflammatory event, our observations identify the importance of ROS in mediating appropriate neutrophil apoptosis and the importance of apoptosis in inflammation and pathology during chronic infection.

Divergent roles for Ly6C+CCR2+CX3CR1+ inflammatory monocytes during primary or secondary infection of the skin with the intra-phagosomal pathogen Leishmania major.

Inflammatory monocytes can be manipulated by environmental cues to perform multiple functions. To define the role of monocytes during primary or secondary infection with an intra-phagosomal pathogen we employed Leishmania major-red fluorescent protein (RFP) parasites and multi-color flow cytometry to define and enumerate infected and uninfected inflammatory cells in the skin. During primary infection, infected monocytes had altered maturation and were the initial mononuclear host cell for parasite replication. In contrast, at a distal site of secondary infection in mice with a healed but persistent primary infection, this same population rapidly produced inducible nitric oxide synthase (iNOS) in an IFN-γ dependent manner and was critical for parasite killing. Maturation to a dendritic cell-like phenotype was not required for monocyte iNOS-production, and enhanced monocyte recruitment correlated with IFN-γ dependent cxcl10 expression. In contrast, neutrophils appeared to be a safe haven for parasites in both primary and secondary sites. Thus, inflammatory monocytes play divergent roles during primary versus secondary infection with an intra-phagosomal pathogen.

Cutaneous Infection with Leishmania major Mediates Heterologous Protection against Visceral Infection with Leishmania infantum.

Visceral leishmaniasis (VL) is a fatal disease of the internal organs caused by the eukaryotic parasite Leishmania. Control of VL would best be achieved through vaccination. However, this has proven to be difficult partly because the correlates of protective immunity are not fully understood. In contrast, protective immunity against nonfatal cutaneous leishmaniasis (CL) is well defined and mediated by rapidly recruited, IFN-γ-producing Ly6C(+)CD4(+) T cells at the dermal challenge site. Protection against CL is best achieved by prior infection or live vaccination with Leishmania major, termed leishmanization. A long-standing question is whether prior CL or leishmanization can protect against VL. Employing an intradermal challenge model in mice, we report that cutaneous infection with Leishmania major provides heterologous protection against visceral infection with Leishmania infantum. Protection was associated with a robust CD4(+) T cell response at the dermal challenge site and in the viscera. In vivo labeling of circulating cells revealed that increased frequencies of IFN-γ(+)CD4(+) T cells at sites of infection are due to recruitment or retention of cells in the tissue, rather than increased numbers of cells trapped in the vasculature. Shortly after challenge, IFN-γ-producing cells were highly enriched for Ly6C(+)T-bet(+) cells in the viscera. Surprisingly, this heterologous immunity was superior to homologous immunity mediated by prior infection with L. infantum. Our observations demonstrate a common mechanism of protection against different clinical forms of leishmaniasis. The efficacy of leishmanization against VL may warrant the introduction of the practice in VL endemic areas or during outbreaks of disease.

Site-dependent recruitment of inflammatory cells determines the effective dose of Leishmania major.

The route of pathogen inoculation by needle has been shown to influence the outcome of infection. Employing needle inoculation of the obligately intracellular parasite Leishmania major, which is transmitted in nature following intradermal (i.d.) deposition of parasites by the bite of an infected sand fly, we identified differences in the preexisting and acute cellular responses in mice following i.d. inoculation of the ear, subcutaneous (s.c.) inoculation of the footpad, or inoculation of the peritoneal cavity (intraperitoneal [i.p.] inoculation). Initiation of infection at different sites was associated with different phagocytic populations. Neutrophils were the dominant infected cells following i.d., but not s.c. or i.p., inoculation. Inoculation of the ear dermis resulted in higher frequencies of total and infected neutrophils than inoculation of the footpad, and these higher frequencies were associated with a 10-fold increase in early parasite loads. Following inoculation of the ear in the absence of neutrophils, parasite phagocytosis by other cell types did not increase, and fewer parasites were able to establish infection. The frequency of infected neutrophils within the total infected CD11b(+) population was higher than the frequency of total neutrophils within the total CD11b(+) population, demonstrating that neutrophils are overrepresented as a proportion of infected cells. Employing i.d. inoculation to model sand fly transmission of parasites has significant consequences for infection outcome relative to that of s.c. or i.p. inoculation, including the phenotype of infected cells and the number of parasites that establish infection. Vector-borne infections initiated in the dermis likely involve adaptations to this unique microenvironment. Bypassing or altering this initial step has significant consequences for infection.

Dancing in a culture of disordered eating: A feminist poststructural analysis of body and body image among young girls in the world of dance.

Eating disorders among adolescent girls are a public health concern. Adolescent girls that participate in aesthetic sport, such as dance, are of particular concern as they experience the highest rates of clinical eating disorders. The purpose of this study is to explore the experiences of young girls in the world of competitive dance and examine how these experiences shape their relationship with the body; feminist poststructural discourse analysis was employed to critically explore this relationship. Interviews were conducted across Canada with twelve young girls in competitive dance (14-18 years of age) to better understand how the dominant discourses in the world of competitive dance constitute the beliefs, values and practices about body and body image. Environment, parents, coaches, and peers emerged as the largest influencers in shaping the young dancers' relationship with their body. These influencers were found to generate and perpetuate body image discourses that reinforce the ideal dancer's body and negative body image.

Attitudes and Practices of a Sample of Nova Scotian Physicians for the Implementation of HIV Pre-Exposure Prophylaxis.

INTRODUCTION: Pre-exposure prophylaxis (PrEP) is an effective HIV prevention tool that requires the ongoing support of physicians to be accessible. Recently, Nova Scotia experienced a 100% increase in HIV diagnoses. The purpose of this study is to explore the relationship between physicians' support of PrEP, knowledge of PrEP, and PrEP prescribing history using the information-motivation-behavioral (IMB) skills model. METHODS: An online survey was distributed to physicians in Nova Scotia, Canada, and eighty physicians participated. Two exploratory factor analyses were conducted with items from the Support of PrEP scale and Knowledge of PrEP scale. A mediation analysis was conducted to assess if knowledge of PrEP mediated the relationship between support of PrEP and whether physicians have prescribed PrEP in the past. RESULTS: On average, physicians reported strong support for PrEP, and as support for PrEP increased so did knowledge of PrEP. Further, physicians who had prescribed PrEP demonstrated strong knowledge of PrEP and physicians who had not prescribed PrEP reported feeling neutral. The 95% bootstrap confidence interval indirect effect of Support for PrEP on prescription history did not include zero (B = 1.59, 95% BsCI [0.83, 3.57]) demonstrating that the effect of support for PrEP is mediated by knowledge of PrEP. The most commonly identified barrier to prescribing PrEP was the lack of drug coverage among patients. CONCLUSION: The results of the mediation analysis support the IMB skills model regarding support for PrEP, Knowledge of PrEP, and having prescribed PrEP in the past. Our findings suggest that to improve PrEP uptake in Nova Scotia, educational interventions for physicians and universal coverage of the drug would be necessary.

Emergency Physician Survey on Firearm Injury Prevention: Where Can We Improve?

INTRODUCTION: Firearm injury and death is increasingly prevalent in the United States. Emergency physicians (EP) may have a unique role in firearm injury prevention. The aim of this study was to describe EPs' beliefs, attitudes, practices, and barriers to identifying risk of and counseling on firearm injury prevention with patients. A secondary aim was assessment of perceived personal vulnerability to firearm injury while working in the emergency department (ED). METHODS: We conducted a cross-sectional survey of a national convenience sample of EPs, using questions adapted from the American College of Surgeons' Committee on Trauma 2017 survey of surgeons. Descriptive statistics and chi-square tests were calculated as appropriate. RESULTS: A total of 1901 surveys were completed by EPs from across the United States. Among respondents, 42.9% had a firearm at home, and 56.0% had received firearm safety training. Although 51.4% of physicians in our sample were comfortable discussing firearm access with their high-risk patients, more than 70% agreed or strongly agreed that they wanted training on procedures to follow when they identify that a patient is at high risk of firearm injury. Respondents reported a variety of current practices regarding screening, counseling, and resource use for patients at high risk of firearm injury; the highest awareness and self-reported screening and counseling on firearm safety was with patients with suicidal ideation. Although 92.3% of EPs reported concerns about personal safety associated with firearms in the ED, 48.1% reported that there was either no protocol for dealing with a firearm in the ED, or if there was a protocol, they were not aware of it. Differences in demographics, knowledge, attitudes, and behavior were observed between respondents with a firearm in the home, and those without a firearm in the home. CONCLUSIONS: Among respondents to this national survey of a convenience sample of EPs, approximately 40% had a firearm at home. The majority reported wanting increased education and training to identify and counsel ED patients at high risk for firearm injury. Improved guidance on personal safety regarding firearms in the ED is also needed.

Feasibility and Cost of Using Instagram to Recruit Adolescents to a Remote Intervention.

PURPOSE: The purpose of this study was to describe the feasibility, cost-effectiveness, and generalizability of a strategy for recruiting adolescents into research studies through social media. METHODS: We designed and tested six Instagram advertisements (ads) with a combination of Instagram campaign objectives (Traffic vs. Reach) and types of placement (Story vs. Feed). The goal was to obtain remote assent and screen for a larger remote behavioral intervention study. The eligibility criteria for screening were being aged 13-17 years, residing in the United States, and English-speaking. The eligibility for the larger study was past year cybervictimization and smartphone ownership. A target sample was 80 participants, randomly assigned to a control or intervention group and followed up for 16 weeks. Recruitment rates and cost-per-enrolled participant with different advertising strategies, demographics, and retention were examined using descriptive statistics. RESULTS: The six ads were run over 907.5 hours, generating 1,069,747 impressions, 2,051 click-throughs, and 663 completed screening surveys. Of 493 eligible participants, 24.4% assented to participate, 69.4% completed enrollment, and 4.8% dropped/withdrew after randomization. Average advertising costs were $52/participant; the lowest-cost strategy (Traffic campaign + Feed ad placement) was $19/enrolled participant. The study sample was largely white (81.3%), non-Hispanic (87.5%), and female (77.5%) with an average age of 15.33 years. Nearly half of the participants were identified as lesbian, gay, or bisexual. More than 96% of participants were retained at the 16-week follow-up. CONCLUSIONS: Instagram can be a feasible and cost-effective way to recruit adolescents for a remote study. This method may be ideal for recruiting hard-to-reach audiences.

Implications of interprofessional primary care team characteristics for health services and patient health outcomes: A systematic review with narrative synthesis.

Interprofessional primary care (IPPC) teams are promoted as an alternative to single profession physician practices in primary care with focus on preventive care and chronic disease management. Characteristics of teams can have an impact on their performance. We synthesized quantitative, qualitative or mixed-methods evidence addressing the design of IPPC teams. We searched Ovid MEDLINE, Embase, CINAHL, and PAIS using search terms focused on IPPC teams. Studies were included if they discussed the influence of team structure, organization, financial arrangements, or policies and procedures, or either health care processes or outputs, health outcomes, or costs, and were conducted in Australia, Canada, the United Kingdom or New Zealand between 2003 and 2016. We screened 11,707 titles, 5366 abstracts, and selected 77 full text articles (38 qualitative, 31 quantitative and 8 mixed-methods). Literature focused on the implications of team characteristics on team processes, such as teamwork, collaboration, or satisfaction of patients or providers. Despite heterogeneity of contexts, some trends are observable: shared space, common vision and goals, clear definitions of roles, and leadership as important to good teamwork. The impacts of these on health care outputs or patient health are not clear. To move the state of knowledge beyond perception of what works well for IPPC teams, researchers should focus on quantitative causal inference about the linkages between team characteristics and patient health.

Sharpening the focus: differentiating between focus groups for patient engagement vs. qualitative research.

PLAIN ENGLISH SUMMARY: Patient engagement is an opportunity for people with experience of a health-related issue to contribute to research on that issue. The Canadian Strategy for Patient-Oriented Research (SPOR) highlights patient engagement as an important part of health research. Patient engagement, however, is a new concept for many researchers and research ethics boards, and it can be difficult to understand the differences between patient engagement activities and research activities. Focus groups are one example of how research and patient engagement activities are often confused.We distinguish these two types of activities by using different terms for each. We use focus groups to refer to research activities, and discussion groups to refer to patient engagement activities. In focus groups, researchers collect data by speaking with a group of research subjects about their experiences. Researchers use this information to answer research questions and share their findings in academic journals and gatherings. In patient engagement, discussion groups are a way for patients to help plan research projects. Their contributions are not treated as research data, but instead they help make decisions that shape the research process. We have found that using different language to refer to each type of activity has led to improved clarity in research planning and research ethics submissions. ABSTRACT: Background In patient-oriented research (POR), focus groups can be used as a method in both qualitative research and in patient engagement. Canadian health systems researchers and research ethics boards (REBs), however, are often unaware of the key differences to consider when using focus groups for these two distinct purposes. Furthermore, no one has clearly established how using focus groups for these two purposes should be differentiated in the context of Canada's Strategy for Patient-Oriented Research (SPOR), which emphasizes appropriate patient engagement as a fundamental component of POR. Body Researchers and staff in the Maritime SPOR SUPPORT Unit refer to focus groups in patient engagement as discussion groups for clarity, and have developed internal guidelines to encourage their appropriate use. In this paper, the guidelines comparing and contrasting the design and conduct of focus groups and of discussion groups is described, including: the theoretical framework for each; the need for research ethics board review approval; identifying participants; collecting and analyzing data; ensuring rigour; and disseminating results. Conclusion The MSSU guidelines address an important and current methodological challenge in patient-oriented research, which will benefit Canadian and international health systems researchers, patients, and institutional REBs.

[High frequency of dyslipidemia in VIH-infected patients in aa peruvian public hospital]. / Elevada frecuencia disclipidemia en pacientes infectados por VIH en un Hospital público peruano.

The objective of the study was to determine the frequency and characteristics of dyslipidemia in patients with HIV in highly active antiretroviral therapy (HAART) in a Peruvian public hospital. A cross-sectional study was carried out in patients with complete lipid profile after receiving at least six months of HAART. Dyslipidemia was defined according to the criteria of the NCEP-ATP III. We reviewed 2 975 clinical histories, and included 538 (18.1%) in the analysis. The frequency of dyslipidemia was 74.7%. HAART regimens which include protease inhibitors (PI) (odds ratio [OR]: 1.22; confidence interval at 95% [CI 95%]: 1.11-1.33) and to be older than 40 years (OR: 1.17; CI 95%: 1.05-1.28) were associated with dyslipidemia, adjusted by viral load, CD4 lymphocyte level and gender. In conclusion, dyslipidemia was very common in our sample and was mainly associated with the use of PI. It is necessary to promote the dyslipidemia control as part of the comprehensive care of the patient with HIV.

El objetivo del estudio fue determinar la frecuencia y características de la dislipidemia en pacientes con VIH en terapia antirretroviral de gran actividad (TARGA) en un hospital público peruano. Se realizó un estudio transversal en pacientes que tuvieran un perfil lipídico completo luego de recibir al menos seis meses de TARGA. La dislipidemia se definió según los criterios NCEP-ATP III. Se revisaron 2975 historias clínicas, 538 (18.1%) fueron incluidas en el análisis. La frecuencia de dislipidemia fue 74.7%. Los esquemas de TARGA que incluían inhibidores de la proteasa (IP) (OR 1.22; IC95% 1,11-1,34) y la edad mayor de 40 años (OR 1.17; IC95% 1,06-1,29) mostraron asociación con dislipidemia, ajustado por carga viral, nivel de células CD4 y sexo. En conclusión, la dislipidemia fue muy frecuente en la muestra estudiada y estuvo asociada principalmente al uso de IP. Es necesario promover el control de la dislipidemia como parte de la atención integral del paciente con infección por VIH.
