RESUMEN
We present two cases of complex metacarpal fractures treated with an intramedullary locking nail. This is an emerging fixation method that minimizes tissue insult, provides sufficient stability, and allows early mobilization. Locking nails accommodate the capture of fractured fragments in complex unstable patterns and provide longitudinal and rotational stability. The described intrafocal technique is intended to improve coaxial placement of the wire into the medullary canal.
RESUMEN
BACKGROUND: As a large number of people live with HIV, it is worthwhile to examine the integration of this group in the workplace. OBJECTIVE: To investigate how the operationalization of GIPA/MEPA supports workplace policies and practices for PLHIV. The study aims to explore what is being offered to support PLHIV in community-based agencies and what can be done to enhance the offerings. METHODS: For this community-based research, 2 bilingual online surveys were sent to 150 Canadian organizations that work closely with PLHIV or offer support to them. One of the surveys was for Executive Directors of these organizations while the other was sent to peers; i.e. PLHIV whose job is to offer services to PLHIV. Questions in the surveys varied between open-ended, binary, and Likert. RESULTS: GIPA/MEPA are implemented in most organizations and Executive Directors affirmed that PLHIV and their impacts on the workplace are valued. There is a consensus among Executive Directors that formal support is provided but most respondents argued that this support is not specific for PLHIV. More than half of respondents were either unaware or uncertain about the existence of informal support. Peer-employees claimed that one of the challenges of disclosing HIV to receive peer support is that they may face stigma. CONCLUSION: The application of GIPA/MEPA results in positive outcomes in the workplace. The study emphasizes the need to facilitate access to informal support.

Purpose: The goal of surgical management for unstable elbow injuries is the restoration of joint concentricity and stability. After internal fixation, concerns may exist regarding instability or durability of the fixation construct. Historically, these scenarios were treated with options such as transarticular pinning or external fixation. Recently, an internal joint stabilizer (IJS) that allows postoperative mobilization was introduced. Our objective was to systematically review the literature to aggregate the clinical and biomechanical evidence for the IJS of the elbow. Methods: A systematic review of the PubMed and Google Scholar databases was performed, following the PRISMA guidelines. The search results were narrowed from 2015 through 2023 to coincide with the inception of the device being reviewed. Results: A total of nine retrospective reports on the IJS (N = 171) cases at a mean follow-up of 10.8 months were included. The pooled rate of implant failure was 4.4%, and recurrent instability was 4.1%. Additionally, the we included seven case reports and two biomechanical reports. Conclusions: The aggregate literature describes satisfactory clinical outcomes with low rates of recurrent instability and device failure for the IJS of the elbow. The limited biomechanical investigations conclude efficacy for stability profiles. Clinical relevance: Across a spectrum of unstable elbow cases, the IJS prevented recurrent instability during the early postoperative period. Notably, the device requires an additional procedure for removal, and the long-term impact of the retained devices is currently unclear.
RESUMEN
The link between children exposed to intimate partner violence (IPV) and child maltreatment is well established; however, less is known about the impact children's presence may have on domestic violence disputes. This study investigated the role of children's presence in IPV police calls using data (N = 2709) from supplementary reports provided by an Ontario, Canada police force, one-third of which led to criminal charges (n = 909). When children were present: charges were less likely to be laid; the accused's emotional state was more likely to be rated by police as calm and the accused was less likely to be identified as using alcohol and/or drugs at the time of the call; and victim support interventions were more likely to be offered and accepted. Findings were considered in the context of when charges were laid versus not laid. Implications for police and support service interventions were discussed.

BACKGROUND: Many community-based HIV research studies incorporate principles of greater involvement and meaningful engagement of people living with HIV (GIPA/MEPA) by training people with HIV as peer researchers. Unfortunately, there are still some aspects of research (e.g., quantitative data analysis and interpretation) where many projects fall short in realizing GIPA/MEPA principles. To address these gaps, we developed an eight-week training course that aimed to build the capacity of peer researchers around the understanding and interpretation of quantitative data and incorporating lived experience to increase the impact of the knowledge transfer and exchange phase of a study. METHODS: Peer researchers (n = 8) participated from British Columbia, Alberta, and Ontario and lessons learned from the training were implemented throughout the dissemination of research findings from the People Living with HIV Stigma Index study. This paper presents the curriculum and main training components, course evaluation results, and challenges and lessons learned. The manuscript was created in collaboration with and includes the perspectives of both the peer researchers involved in the training, as well the course facilitators. RESULTS: Throughout the course, peer researchers' self-assessed knowledge and understanding of quantitative research and data storytelling improved and, through interactive activities and practice, they gained the confidence to deliver a full research presentation. This improved their understanding of research findings, which was beneficial for discussing results with community partners and study participants. The peer researchers also agreed that learning about integrating lived experience with quantitative data has helped them to make research findings more relatable and convey key messages in a more meaningful way. CONCLUSIONS: Our training curriculum provides a template for research teams to build capacity in areas of research where peer researchers and community members are less often engaged. In doing so, we continue to uphold the principles of GIPA/MEPA and enhance the translation of research knowledge in communities most greatly affected.
Engaging patient groups or community members is commonplace in HIV research where people living with HIV are trained as peer researchers. There are still however some gaps where community members are less engaged, especially in quantitative data analysis. This presents a barrier preventing them from being meaningfully engaged in research about them. To build capacity in these areas, we designed an eight-week online course that taught peer researchers about quantitative data analysis and interpretation with a focus on concepts that would be important for talking about key messages from research findings. This was used to enhance the knowledge translation and dissemination initiatives for the People Living with HIV Stigma Index studya survey tool containing quantitative measures examining stigma and related health factors. Peer researchers agreed that their knowledge and understanding of the key quantitative data concepts improved significantly throughout the course. This increased understanding helped them discuss quantitative data with community members and study participants, which was important to ensure that research findings reach the affected communities. Peer researchers also agreed that incorporating their new data analysis knowledge with existing lived experience helped them to make findings more relatable and understandable which is critical for translating knowledge to other researchers and policy makers. Overall, our training curriculum gave peer researchers the confidence to talk about quantitative data and improve their capacity to disseminate research. This work also provides guidelines for training peer researchers and ensuring that they are meaningfully engaged in research studies they are a part of.
RESUMEN
OBJECTIVES: To examine clinical gait parameters, hip muscle strength, pelvic functional outcomes, and psychological outcomes after surgical fixation of OTA/AO 61-B and 61-C pelvic ring injuries. DESIGN: Retrospective review identified 10 OTA/AO 61-B patients and 9 OTA/AO 61-C patients for recruitment who were between 1 and 5 years after pelvic fixation. Gait and strength assessments, and patient-reported outcome scores were performed/collected and analyzed. SETTING: Outpatient clinical motion performance laboratory. PATIENTS/PARTICIPANTS: Patients with OTA/AO 61-B and OTA/AO 61-C fractures who were between 1 and 5 years after pelvic fixation. MAIN OUTCOME MEASUREMENTS: Hip strength, kinetics, and spatial-temporal outcomes; Majeed Pelvic Outcome Score; Short Form 36; Hamilton Anxiety/Depression Rating Scales. RESULTS: There were no differences in age, body mass index, or time since definitive fixation between OTA/AO 61-B and 61-C groups. The OTA/AO 61-C group had higher median injury severity scores, longer length of stay, and greater postoperative pelvic fracture displacement. There was no difference in bilateral hip strength, bilateral peak hip moments, peak hip power, and walking speed between groups. Patients with OTA/AO 61-C fractures had lower scores on Short Form 36 General Health and Majeed Work, with a trend toward a lower Total Majeed score. There were no differences in self-reported total anxiety and depression symptoms. CONCLUSIONS: This study did not identify any gait, strength, or psychological differences between OTA/AO 61-B and 61-C injuries at 1-5 years of follow-up. However, increased injury severity in OTA/AO 61-C patients may have residual consequences on perceived general health and ability to work. This pilot study establishes a template for future research into functional recovery of patients with severe pelvic ring trauma. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

PURPOSE: To determine if regional anesthesia had added benefit to general anesthesia, with or without local anesthesia, in controlling post-operative pain in outpatient orthopedic trauma surgery. METHODS: A retrospective review was performed of prospectively gathered data on 71 patients undergoing outpatient orthopedic trauma surgery. All patients received general anesthesia and an addition 52 patients received additional regional anesthesia. Regional vs. no regional anesthesia groups were compared in terms of post-anesthesia care unit (PACU) pain visual analog scores (VAS), PACU length of stay (LOS), opioid use, and pain control at two weeks. RESULTS: The regional anesthesia group not differ in demographics or proportion of patients receiving local anesthesia, but was less likely to be undergoing major procedures (13% vs. 37%, proportional difference (PD) - 23%; 95% confidence interval (CI) - 46% to - 0.4%). There were no detectable differences in PACU opioid requirements (median difference (MD) - 7.5 mg, CI - 8 to 0), PACU LOS (MD - 13 min, CI - 63 to 24), discharge pain VAS (MD 0, CI - 1 to 1), post-discharge pain VAS (MD 0, CI - 1 to 1), opioid refills (PD - 6%, CI - 31% to 18%), or patient-perceived pain control (PD - 24%, CI - 41% to 0%). On multivariate analysis, regional anesthesia was the only variable negatively associated with patient-perceived pain control at two weeks (Odds Ratio 0.15; 95% CI 0.03 to 0.8). CONCLUSIONS: Regional anesthesia did not improve post-operative opioid requirements, PACU LOS, or patient-reported pain in the immediate or short-term post-operative period.

PURPOSE: To determine the effect of the Orthopaedic Trauma Association (OTA) pain management guidelines for acute musculoskeletal injuries on opioid prescription sizes, pain control, and refills. METHODS: A prospective cohort study was performed at an academic urban level 1 trauma center. 90 patients undergoing outpatient orthopaedic trauma surgery were enrolled before and after the implementation of the OTA pain management guidelines. Adherence to guidelines, pain visual analog scale, and refills were recorded postoperatively and at the 2- and 6-week follow-up visit. RESULTS: After implementation of the guidelines, the number of patients receiving oxycodone decreased from 100 to 27%, with these patients receiving the less potent hydrocodone, instead. The discharge morphine equivalent dose (MED) decreased from a median (interquartile range) of 225 (169-300) to 140 mg (140-210) (p < 0.001). More patients required refills in the guidelines group (42% vs. 20%), resulting in no difference in total MED prescribed (210 (140-280) vs. 225 (169-307)). Adherence to the guidelines occurred in 66% of patients. As-treated analysis of patients with adherent and non-adherent prescriptions found no detectable difference in pain control, number of opioid pills used, or refills at the 2-week and 6-week follow-up. CONCLUSIONS: In the midst of a national opioid crisis, adoption of the OTA's pain management guidelines for orthopaedic trauma surgery warrants further research to determine if it's implementation can reduce the size, variability, and duration of opioid prescriptions. LEVEL OF EVIDENCE: Level II, prospective cohort.

Rates of sexual victimization among Indigenous women are 3 times higher when compared with non-Indigenous women. The purpose of this secondary data analysis was to explore the experiences and recommendations of Indigenous women who reported sexual assault to the police and were not believed. This qualitative study of the experiences of 11 Indigenous women reflects four themes. The women experienced (a) victimization across the lifespan, (b) violent sexual assault, (c) dismissal by police, and (d) survival and resilience. These women were determined to voice their experience and make recommendations for change in the way police respond to sexual assault.

One in four women will experience sexual assault in their lifetime. Although less than 5% of sexual assaults are reported to law enforcement, one in five cases reported to police are deemed baseless (by police) and therefore coded as "unfounded." Police officers are in a unique position to act as gatekeepers for justice in sexual assault cases, given their responsibility to investigate sexual assault reports. However, high rates of unfounded sexual assaults reveal that dismissing sexual violence has become common practice amongst the police. Much of the research on unfounded sexual assault is based on police perceptions of the sexual assault, as indicated in police reports. Women's perspectives about their experiences with police are not represented in research. This qualitative study explored women's experiences when their sexual assault report was disbelieved by the police. Data collection included open-ended and semi-structured interviews with 23 sexual assault survivors. Interviews covered four areas including the sexual assault, the experience with the police, the experience of not being believed, and the impact on their health and well-being. Interviews were audio-recorded, transcribed, and entered into NVIVO for analysis. Data were analyzed using Colaizzi's analytic method, resulting in the identification of four themes, including, (a) vulnerability, (b) drug and alcohol use during the assault, (c) police insensitivity, and (d) police process. The women in this study who experienced a sexual assault and reported the assault to police were hopeful that police would help them and justice would be served. Instead, these women were faced with insensitivity, blaming questions, lack of investigation, and lack of follow-up from the police, all of which contributed to not being believed by the institutions designed to protect them. The findings from this research demonstrate that police officers must gain a deeper understanding of trauma and sensitive communication with survivors of sexual assault.

OBJECTIVES: To compare the incidence of deep surgical site infections (SSI) and acute kidney injuries (AKI) in patients who did and did not receive topical antibiotics during the open treatment of fractures. DESIGN: Retrospective comparative cohort. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: Three hundred ninety-six patients undergoing open fixation of fractures. INTERVENTION: The topical antibiotic group included 78 (20%) patients. Vancomycin only was used in 28 (7%) patients with the median dose (interquartile range) of 1 g (1-2 g) and vancomycin/tobramycin was used in 48 (12%) patients with a median dose (interquartile range) of 2 g (1-2 g)/1.2 g (1.2-1.2 g). MAIN OUTCOME MEASUREMENTS: Deep SSI requiring debridement and AKI (>50% increase in creatinine compared with preoperative level). RESULTS: There was no detectable difference in SSI between the topical antibiotic and control groups (13% vs. 10%, odds ratio (OR) 1.3, 95% confidence interval (CI) 0.6 to 2.9). Variables associated with SSI on multivariate analysis included open fracture (OR 3.2, CI 1.5 to 6.5) and an American Society of Anesthesiologists classification of >2 (OR 2.7, CI 1.3 to 5.3). There was no detectable difference in AKI between the topical antibiotic and control groups (1 (2%) vs. 7 (5%); OR 0.3, CI 0.04 to 3). CONCLUSION: There was no detectable difference, with wide confidence intervals, in SSI and AKI between the topical antibiotic and control groups. Further studies need to be conducted to evaluate the relationship between topical antibiotics and clinical outcomes in orthopaedic trauma surgery. LEVEL OF EVIDENCE: Therapeutic Level III.

BACKGROUND: Sexual assault is a prevalent crime against women globally with known negative effects on health. Recent media reports in Canada indicate that many sexual assault reports are not believed by police. Negative reporting experiences of sexual assault have been associated with secondary victimization and trauma among survivors. However, little is known about the impact that being sexually assaulted and not believed by police has on a survivor's health and well-being. The purpose of this study was to explore women's experiences of not being believed by police after sexual assault and their perceived impact on health. METHODS: We conducted open-ended and semi-structured interviews with 23 sexual assault survivors who were sexually assaulted and not believed by police. The interviews explored the self-reported health impacts of not being believed by police and were conducted from April to July, 2019. All interviews were audio-recorded, transcribed, and entered into NVIVO for analysis. Data were analyzed using Colaizzi's analytic method. RESULTS: Analysis revealed three salient themes regarding the health and social impact of not being believed by police on survivors of sexual assault: (1) Broken Expectations which resulted in loss of trust and secondary victimization, (2) Loss of Self, and (3) Cumulative Health and Social Effects. The findings showed that not being believed by police resulted in additional mental and social burdens beyond that of the sexual assault. Many survivors felt further victimized by police at a time when they needed support, leading to the use taking of alcohol and/or drugs as a coping strategy. CONCLUSION: Reporting a sexual assault and not being believed by police has negative health outcomes for survivors. Improving the disclosure experience is needed to mitigate the negative health and social impacts and promote healing. This is important for police, health, and social service providers who receive sexual assault disclosures and may be able to positively influence the reporting experience and overall health effects.

PURPOSE: Humerus shaft fractures are commonly acutely immobilized with coaptation splints (CS), which can be difficult to apply and poorly tolerated by the patient. Functional splints (FS), which work on the same principle as functional braces, are an alternative to CS. The purpose of this study was to directly compare CS and FS in terms of application and fracture reduction. METHODS: A retrospective review identified humeral shaft fractures managed nonoperatively with initial immobilization in a FS (n = 19) versus a CS (n = 15). In addition, 13 residents completed a blinded survey on splint application. RESULTS: The FS and CS groups did not differ in initial fracture angulation and translation on anteroposterior (AP) and lateral radiographs. Post-splint application, there was no clinically relevant difference in fracture angulation/translation between groups, and this persisted at the subsequent follow-up visit. All residents reported that the FS was easier to apply and took less time. CONCLUSION: This study results demonstrated the FS results in similar reductions in humeral shaft fractures as CS. A survey of residents found that the FS was easier to apply, took less time, and was better tolerated by patients. Subsequently, we prefer the FS over the CS for the acute management of humeral shaft fractures.

BACKGROUND: Excessive opioid prescriptions after orthopedic surgery are common. The purpose of this study was to examine the association between surgical severity, preoperative opioid use and patient characteristics with postoperative opioid prescriptions and refills. METHODS: Seventy-nine patients undergoing orthopedic surgeries were reviewed. Surgical pain severity was categorized as mild (n = 25), moderate (n = 26) and severe (n = 28). Patients were also categorized as opioid naïve (n = 57), experienced (n = 16) and tolerant (n = 6). Postoperative and refill prescriptions were reviewed to determine morphine equivalent dose (MED) prescribed. RESULTS: Mild, moderate and severe pain surgeries received a median (interquartile range) equivalent of 20 (0, 30), 53 (33, 80) and 60 (45, 80) oxycodone 5 mg tablets, respectively. Excessive opioid prescriptions (> 400 MED) were given to 37 (46%) patients. There was no difference in the total discharge MED between moderate and severe pain surgeries or between opioid naïve and opioid-experienced patients (p > 0.05). Variables associated with excessive postoperative opioid prescriptions on multivariate analysis-included severe pain surgery (odds ratio 7.7, 95% confidence interval 2 to 25; p < 0.01) and anesthetic block (odds ratio 4.5, 95% confidence interval 1.4 to 14; p < 0.01). Variables associated with opioid refill on multivariate analysis included an American Society of Anesthiologists Physical Status (ASA) score > I (odds ratio 11, 95% confidence interval: 1.3 to 92; p < 0.01) and preoperative pain VAS (odds ratio 1.2, 95% confidence interval 1.01 to 1.4; p = 0.02). CONCLUSION: The adoption of opioid prescription guidelines is warranted to differentiate between surgical severities and decrease the range and size of postoperative opioid prescriptions.

BACKGROUND: The impact of patient sex on the prevalence of foot and ankle injuries has been established. Reporting of differences on treatment outcomes is lacking. The purpose of this study was to identify trends in sex-specific outcomes across high-impact journals over a 5-year time period. METHODS: Two independent investigators reviewed journal issues published during 2 calendar years (2011 and 2016) in the 5 highest-impact orthopedic foot and ankle/sports subspecialty journals (Foot & Ankle International [FAI], Foot and Ankle Surgery [FAS], American Journal of Sports Medicine [AJSM], Arthroscopy, and Knee Surgery, Sports Traumatology, Arthroscopy [KSSTA]). Studies were stratified into those that involved sex-specific analysis (SSA), where sex was a variable in a multifactorial statistical model, and those that only reported sex as a demographic characteristic or utilized sex-matched cohorts. RESULTS: A total of 473 studies evaluating a total of 273 128 patients met criteria. An average of 43.9% (119 967 patients) of the population were female. Only 16.7% (79/473) of studies included sex as variable in a statistical model. Thirteen percent (25/193) and 19.3% (54/280) of studies reported SSA in 2011 and 2016, respectively. FAI was the only journal demonstrating a significant improvement of reporting SSA from 2011 to 2016 (P < .002). Thirty percent (24/79) of studies that performed SSA demonstrated significant differences between male and female outcomes. CONCLUSION: Reporting of SSA in the orthopedic literature continued to be lacking. Only 16.7% of all articles evaluated in 2011 and 2016 performed SSA, with 30% of this subset reporting a statistically significant difference in outcomes. LEVEL OF EVIDENCE: Level III, comparative study.

BACKGROUND: Dilute chlorhexidine gluconate (CHG) in sterile water is an antiseptic solution approved for intraoperative wound irrigation by the United States Food and Drug Administration. In practice, however, CHG is commonly diluted with normal saline, which can result in its precipitation potentially reducing the antimicrobial effect. The purpose of this study was to determine if the antimicrobial properties of CHG are reduced after dilution with normal saline compared to sterile water. MATERIALS AND METHODS: Sterile paper disks were placed into undiluted 4% CHG (positive control), 0.05% CHG in sterile water, 0.05% CHG in normal saline, or normal saline alone (negative control) and then placed in triplicate onto the agar plates inoculated with Staphylococcus aureus. After incubating at 37 °C for 24 h, the diameter of the zone of inhibition around each disk was measured. RESULTS: The mean zone of inhibition for 4% CHG, 0.05% CHG in sterile water, 0.05% CHG in normal saline, and normal saline alone was 24 ± 0.6 mm, 16 ± 0.9 mm, 14 ± 0.5 mm, and 0 ± 0 mm, respectively (p < 0.01). The zone of inhibition for dilute CHG in normal saline was on average 2.5 mm less (95% CI 1.7-3.2 mm) than that of CHG in sterile water. CONCLUSIONS: Dilute CHG in normal saline, versus sterile water, retained its antimicrobial activity with a small reduction in the zone of inhibition. Surgeons and scientists should be aware of the interaction between normal saline and CHG. Future scientific studies need to control for what solution is used for dilution.

INTRODUCTION: Injuries to the critical structures underlying the clavicle are possible during open reduction and internal fixation (ORIF) and afterward secondary to prominent screws. The purpose of this study was to identify patients who received chest computerized tomography (CT) scans after clavicle ORIF to evaluate the distance between the screws and the subclavian vessels. METHODS: A retrospective review was performed at a single level-one trauma center. Nineteen patients with chest CT scans after superior plate fixation were included. Coronal CT reconstructions were analyzed to determine distances between the subclavian vessels and screw tips along with the prominence of the screws. Vessels within 15 mm of the screw were considered at risk. RESULTS: None of the screws (0/142) were within 15 mm of the subclavian vessels. Average screw prominence was 1.3 ± 1 mm (range, 0-3.6 mm). One of the 19 patients had a complication, a re-fracture requiring revision ORIF. The remaining 18 patients had no complications, including neurovascular or pulmonary, at the last follow-up. CONCLUSIONS: None of the screws were excessively prominent or within 15 mm of the subclavian vessels. Attentive superior plate fixation of the clavicle with screws is a safe technique. LEVEL OF EVIDENCE: Level IV, case series.

BACKGROUND: Building the collective capacity of racialized women to meaningfully lead and engage in research is critical to health equity. To address the silence and stigma related to HIV/sexually transmitted infections (STIs) among South Asian women in Canada, peer leadership and engagement were identified as important strategies to promote open discussion about sexual health. OBJECTIVES: Underpinned by the principle of 'nothing about us without us', the objectives of the Story Sharing for Sexual Health (SSSH) research study included engaging and training South Asian women peer leaders to become an integral part of the study and build community research capacity. To achieve these objectives, it was critical to support the peer leaders in gaining a thorough understanding of the research ethics, protocols and teamwork principles, and to consolidate skills in group facilitation and community engagement. METHODS: The peer leaders attended four full-day training sessions on the social determinants of health and gender equity for racialized populations, HIV/STI and sexual health in the context of South Asian communities, community-based participatory research (CBPR) principles, skills in focus group facilitation, community partnerships building, and storytelling epistemologies. A training manual was developed. Evaluation of the training program included 1) evaluation forms, 2) process evaluations through journal writing and feedback sessions, and 3) implementation outcomes. CONCLUSIONS: The SSSH peer research training program was effective. Peer leaders demonstrated effectiveness in liaising with partner agencies, engaging South Asian women in sexual health discussion, completing CBPR activities and team building. Knowledge generated can be applied in CBPR with other racialized women populations.

Story-based learning is well recognized as an effective strategy for adult health education. However, there is a scarcity of research on story-based health education among women in South Asian diasporic communities. To address this gap, we undertook a pilot study in Toronto to explore how South Asian women respond to the use of fact-based and story-based materials for HIV/STI prevention. A total of 78 women were recruited from across the city. We engaged nearly half of the women (n=40) using fact sheets on HIV/STIs, and the remainder (n=38) using stories written by South Asian women on HIV/STIs. Surveys and focus groups were used to explore participants' responses in terms of knowledge, attitudes and perspectives. Results indicated that both approaches were effective in increasing participants' knowledge of HIV/STIs. Participants in the fact-based sessions tended to distance themselves from the idea of personal HIV/STI risks. Participants in the story-based groups were emotionally engaged, expressing personal commitments to take a stand against HIV stigma. In summary, within-culture stories are potentially effective tools that enable women to make sense of their own life situations and contextual vulnerabilities. Story-based materials are useful for breaking the silence of taboo topics, addressing stigma and discrimination and raising awareness about collective empowerment.
