[Bone marrow fibrosis in primary myelofibrosis in relation to myelodysplasia- and age-related mutations of hematopoietic cells]

Besides histopathological findings, there are no indicators of increased risk for fibrotic progression in myeloproliferative neoplasms (MPNs). Age-related clonal hematopoiesis (ARCH) or clonal hematopoiesis of indetermined potential (CHIP) are frequent findings in the elderly and combinations with MPN driver mutations (JAK2, MPL, and CALR) have been described. To determine the impact of ARCH/CHIP-related mutations for the development of fibrosis in primary myelofibrosis (PMF), the mutational status of cases with fibrotic progression from grade 0 to grade 2/3 (n = 77) as evidenced by follow-up bone marrow biopsies (median 6.2 years) was compared to prefibrotic PMF samples without the development of fibrosis (n = 27; median follow-up 7.3 years). Frequent ARCH/CHIP-associated mutations (TET2, ASXL1, DNMT3A) demonstrable at presentation were not connected with fibrotic progression. However, mutations that are rarely found in ARCH/CHIP (SRSF2, U2AF1, SF3B1, IDH1/2, and EZH2) were present in 24.7% of cases with later development of fibrosis and not detectable in cases staying free from fibrosis (P = 0.0028). Determination of tumor mutational burden (TMB) in a subgroup of cases (n = 32) did not show significant differences (7.68 mutations/MB vs. 6.85 mutations/MB). We conclude that mutations rarely found in ARCH/CHIP provide an independent risk factor for rapid fibrotic progression (median 2.0 years) when already manifest at first presentation.

Analysis of the relationship between earthquake-related losses and the frequency of child-directed emotional, physical, and severe physical abuse in Haiti

BACKGROUND

Child abuse is a public health and human rights issue that is prevalent worldwide. All forms of abuse against children can have negative physical and mental health consequences. Under post-disaster situations, where there is a potential for increased stress and decreased social support among caregivers, the risk of child abuse may be higher.

OBJECTIVE

To explore the association between earthquake-related losses (family-related and property-related) and the experience of emotional, physical, and severe physical child abuse in the household for children aged 2-14 in Haiti.

METHODS

A nationally representative sample of Haitian households from the 2012 Demographic and Health Survey (DHS) was used. Descriptive analyses were summarized using frequencies and measures of central tendency. Associations between earthquake-related loss and child abuse was assessed using log-binomial regression modelling.

RESULTS

Two years following the earthquake, and after considering potentially confounding variables, death of a household member was associated with a higher likelihood of a child being victim to emotional (RR = 1.11, 95 % CI: 1.05-1.17) and severe physical abuse (RR = 1.50, 95 % CI: 1.15-1.96). Conversely, injury of a household member was associated with a lower likelihood of a child experiencing emotional abuse (RR = 0.93, 95 % CI: 0.87-0.99).

CONCLUSIONS

There were associations between earthquake-related losses and some forms of child abuse; the results were not consistent across all exposures and outcomes. The high prevalence of reported child abuse indicates a need for interventions to reduce child abuse in homes overall. There is also need for further research into the aetiology and influences specific to different types of abuse.

Experience of emergency department use among persons with a history of adverse childhood experiences

BACKGROUND

Adverse childhood experiences (ACEs) are associated with increased morbidity and mortality, lower levels of distress tolerance, and greater emotional dysregulation, as well as with increased healthcare utilization. All these factors may lead to an increased use of emergency department (ED) services. Understanding the experience of ED utilization among a group of ED users with high ACE scores, as well as their experiences as viewed through the lens of a trauma and violence informed care (TVIC) framework, could be important to their provision of care.

METHODS

This is the qualitative portion of a larger mixed methods study. Twenty-five ED users with high ACE scores completed in depth interviews. Thematic analysis of the interview transcripts was undertaken and directed content analysis was used to examine the transcripts against a TVIC framework.

RESULTS

The majority of participants experienced excellent care although challenges to this experience were faced by many in the areas of registration and triage. Some participants did identify negative experiences of care and stigma when presenting with mental health conditions and pain crises, as did participants who perceived that they were considered "different" (dressed differently, living in poverty, young parents, etc.). Participants were thoughtful about their reasons for seeking ED care including lack of timely access to their family doctor, perceived urgency of their condition, or needs that fell outside the scope of primary care. Participants' experiences mapped onto a TVIC framework such that their needs and experiences could be framed using a TVIC lens.

CONCLUSIONS

While the ED care experience was excellent for most participants, even those with a trauma history, there existed a subset of vulnerable patients for whom the principles of TVIC were not met, and for whom implementation of trauma informed care might have a positive impact on the overall experience of care. Recommendations include training around TVIC for ED leadership, staff and physicians, improved access to semi-urgent primary care, ED patient care plans integrating TVIC principles, and improved support for triage nurses and registration personnel.

[Liquid biopsy in tumor diagnostics : Applications, perspectives, and limitations of the "cancer liquidome"]

The detection of tumor-specific genetic alterations in body fluids as an addition to or even replacement for established tissue-based tumor diagnostics is currently a hot topic in academic research and industry. Progress in methods for nucleic acid analyses together with promising results from clinical studies have raised great expectations for cancer screening, diagnosis, prognosis, and therapy monitoring by means of a minimally invasive blood draw. Individual focused assays have already been introduced into routine diagnostics and represent a valuable option in cases where no tissue samples are available. However, before the use of liquid biopsy outside of clinical studies is enforced and more complex markers (like tumor mutational burden) are analyzed, several practical challenges and principal problems have to be addressed. This review focusses on the detection of free-circulating nucleic acids in blood plasma and critically discusses established and future applications as well as challenges and limitations of this new method.

OBJECTIVES

The Global Emergency Medicine Literature Review (GEMLR) conducts an annual search of peer-reviewed and gray literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most important new research in this field to a global audience of academics and clinical practitioners.

METHODS

This year, 17,722 articles written in three languages were identified by our electronic search. These articles were distributed among 20 reviewers for initial screening based on their relevance to the field of global EM. Another two reviewers searched the gray literature, yielding an additional 11 articles. All articles that were deemed appropriate by at least one reviewer and approved by their editor underwent formal scoring of overall quality and importance. Two independent reviewers scored all articles.

RESULTS

A total of 848 articles met our inclusion criteria and underwent full review. Sixty-three percent were categorized as emergency care in resource-limited settings, 23% as disaster and humanitarian response, and 14% as EM development. Twenty-one articles received scores of 18.5 or higher out of a maximum score 20 and were selected for formal summary and critique. Inter-rater reliability testing between reviewers revealed a Cohen's kappa of 0.344.

CONCLUSIONS

In 2017, the total number of articles identified by our search continued to increase. Studies and reviews with a focus on infectious diseases, pediatrics, and trauma represented the majority of top-scoring articles.

Implementation of a SenseMaker® research project among Syrian refugees in Lebanon

The Syrian conflict has displaced over 1.2 million Syrians into Lebanon. As a result of displacement, some Syrian families are turning to child marriage as a coping mechanism. The prevalence of early marriage has reportedly increased and the average age of marriage decreased during the crisis. The aim of the project was to understand the underlying factors contributing to child marriage among Syrian refugees in Lebanon using Cognitive Edge’s SenseMaker®. This manuscript explores the process of implementing this novel research tool in a humanitarian setting. Twelve interviewers conducted SenseMaker® interviews with married and unmarried Syrian girls, Syrian parents, as well as married and unmarried men. Participants were asked to share a story about the lives of Syrian girls in Lebanon and to self-interpret the narratives by answering follow-up questions in relation to the story provided. Data collection occurred across three locations: Beirut, Beqaa, and Tripoli. In total 1422 narratives from 1346 unique participants were collected over 7 weeks. Data collection using SenseMaker® was efficient, capable of electronically capturing a large volume of quantitative and qualitative data. SenseMaker® limitations from a research perspective include lack of skip logic and inability to adjust font size on the iOS app. SenseMaker® was an efficient mixed methods data collection tool that was well received by participants in a refugee setting in Lebanon. The utility of SenseMaker® for research could be improved by adding skip logic and by being able to adjust font size on the iOS app.

A qualitative analysis of decision-making among women with sexual violence-related pregnancies in conflict-affected eastern Democratic Republic of the Congo

BACKGROUND

Sexual violence is prevalent in conflict-affected settings and may result in sexual violence-related pregnancies (SVRPs). There are limited data on how women with SVRPs make decisions about pregnancy continuation or termination, especially in contexts with limited or restricted access to comprehensive reproductive health services.

METHODS

A qualitative study was conducted in Bukavu, Democratic Republic of the Congo (DRC) as part of a larger mixed methods study in 2012. Utilizing respondent-driven sampling (RDS), adult women who self-reported sexual violence and a resultant SVRP were enrolled into two study subgroups: 1) women currently raising a child from an SVRP (parenting group) and 2) women who terminated an SVRP (termination group). Trained female research assistants conducted semi-structured interviews with a subset of women in a private setting and responses were manually recorded. Interview notes were translated and uploaded to a qualitative software program, coded, and thematic content analysis was conducted.

RESULTS

A total of 55 women were interviewed: 38 in the parenting group and 17 in the termination group. There were a myriad of expressed attitudes, beliefs, and emotional responses toward SVRPs and the termination of SVRPs with three predominant influences on decision-making, including: 1) the biologic, ethnic, and social identities of the fetus and/or future child; 2) social reactions, including fear of social stigmatization and/or rejection; and 3) the power of religious beliefs and moral considerations on women's autonomy in the decision-making process.

CONCLUSION

Findings from women who continued and women who terminated SVRPs reveal the complexities of decision-making related to SVRPs, including the emotional reasoning and responses, and the social, moral, and religious dimensions of the decision-making processes. It is important to consider these multi-faceted influences on decision-making for women with SVRPs in conflict-affected settings in order to improve provision of health services and to offer useful insights for subsequent programmatic and policy decisions.

A qualitative analysis of psychosocial outcomes among women with sexual violence-related pregnancies in eastern Democratic Republic of Congo

BACKGROUND

Sexual violence is prevalent in eastern Democratic Republic of Congo (DRC) and has potentially devastating psychosocial consequences. Previous studies have reported on sexual violence and its impact on the mental health of survivors, but there are few studies conducted among women with sexual violence-related pregnancies (SVRPs). Women with SVRPs may be at greater risk of complex psychosocial outcomes, including social stigmatization. This study aimed to describe psychosocial outcomes among this subgroup of sexual violence survivors in order to inform future interventions.

METHODS

A mixed methods study was conducted in Bukavu, DRC in 2012 among adult women who self-reported an SVRP and either (1) were currently raising a child from an SVRP (parenting group) or (2) had terminated an SVRP (termination group). This manuscript presents qualitative findings from the mixed methods study. Participants were recruited using respondent-driven sampling and a proportion engaged in semi-structured qualitative interviews conducted by trained female interviewers. Thematic content analysis was conducted and key themes were identified.

RESULTS

In total, 55 women were interviewed, of whom 38 were in the parenting group and 17 in the termination group. Women with SVRPs experienced a myriad of emotional responses as they navigated their social environments following the SVRPs. Negative reactions, including social stigmatization and/or social rejection, toward women with SVRPs and toward children born from SVRPs were important influences on psychological well-being. Women expressed both internalized emotionality intertwined with externalized experiences in the social environment. Many women demonstrated resilience, or what could be termed post-traumatic growth, identifying avenues of agency to advance the social conditions for women.

CONCLUSIONS

The findings from the qualitative study, and in particular, the respondents' needs and suggested strategies, may be useful to inform future research, programs, and policies for women with SVRPs in eastern DRC. Future research could move beyond cross-sectional assessments to utilize innovative research methodologies to assess processes of psychological adaptation among women with SVRPs. Multi-dimensional psychosocial programs for women with SVRPs should consider basic needs such as shelter, food, and health care within the broader framework of trauma-informed care. Participatory programming, guided by beneficiaries, could provide further avenues for agency to advance social conditions for women with SVRPs in eastern DRC.

Global Emergency Medicine: A Review of the Literature From 2016

OBJECTIVES

The Global Emergency Medicine Literature Review (GEMLR) conducts an annual search of peer-reviewed and gray literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most important new research in this field to a global audience of academics and clinical practitioners.

METHODS

This year 13,890 articles written in four languages were identified by our search. These articles were distributed among 20 reviewers for initial screening based on their relevance to the field of global EM. An additional two reviewers searched the gray literature. All articles that were deemed appropriate by at least one reviewer and approved by their editor underwent formal scoring of overall quality and importance. Two independent reviewers scored all articles.

RESULTS

A total of 716 articles met our inclusion criteria and underwent full review. Fifty-nine percent were categorized as emergency care in resource-limited settings, 17% as EM development, and 24% as disaster and humanitarian response. Nineteen articles received scores of 18.5 or higher out of a maximum score of 20 and were selected for formal summary and critique. Inter-rater reliability testing between reviewers revealed Cohen's kappa of 0.441.

CONCLUSIONS

In 2016, the total number of articles identified by our search continued to increase. The proportion of articles in each of the three categories remained stable. Studies and reviews with a focus on infectious diseases, pediatrics, and the use of ultrasound in resource-limited settings represented the majority of articles selected for final review.

Sexual violence-related pregnancies in eastern Democratic Republic of Congo: a qualitative analysis of access to pregnancy termination services

BACKGROUND

Sexual violence has been prevalent throughout the armed conflict in eastern Democratic Republic of Congo (DRC). Research on sexual violence-related pregnancies (SVRPs) and pregnancy termination in eastern DRC, a context with high prevalence of sexual violence, high maternal mortality, and restrictive abortion laws, is scant but crucial to improving the overall health of women in the DRC. Understanding women's perceptions and experiences related to an SVRP, and in particular to pregnancy termination in this context, is critical for developing effective, targeted programming.

METHODS

Respondent-driven sampling (RDS) was used to recruit two subgroups of women reporting SVRPs, 1) women raising a child from an SVRP (parenting group) and 2) women who had terminated an SVRP (termination group), in Bukavu, DRC in 2012. Semi-structured qualitative interviews on pregnancy history and outcomes were conducted with a systematically selected sub-group of women recruited through RDS methodology. Interview responses were translated, transcribed and uploaded to the qualitative data analysis software Dedoose. Thematic content analysis, complemented by the constant comparative technique from grounded theory, was subsequently used as the analytic approach for data analysis.

RESULTS

Fifty-five qualitative interviews (38 parenting group and 17 termination group) were completed. The majority of women in the termination group reported using traditional herbs to terminate the SVRP, which they often obtained on their own or through family, friends and traditional healers; whereas women in the parenting group reported ongoing pregnancies after attempting pregnancy termination with herbal medications. Three women in the termination group reported accessing services in a health center. Almost half of the women in the parenting group cited fear of death from termination as a reason for continuing the pregnancy. Other women in the parenting group contemplated pregnancy termination, but did not know where to access services. Potential legal ramifications and religious beliefs also influenced access to services.

CONCLUSIONS

Women in this study had limited access to evidence-based safe abortion care and faced potential consequences from unsafe abortion, including increased morbidity and mortality. Increased access to reproductive health services, particularly safe, evidence-based abortion services, is paramount for women with SVRPs in eastern DRC and other conflict-affected regions.

A Qualitative Analysis of Disclosure Patterns among Women with Sexual Violence-Related Pregnancies in Eastern Democratic Republic of Congo

The Democratic Republic of the Congo (DRC) has experienced nearly two decades of civil conflict in the Eastern regions of North and South Kivu. This conflict has been notorious for the use of sexual violence as a weapon of war, leading in many cases to pregnancy after rape. The objectives of this analysis were: 1) to describe patterns of sexual violence-related pregnancy (SVRP) disclosure; 2) to consider why survivors chose to disclose to particular individuals; and 3) to examine the dialogue around SVRPs between women with SVRPs and their confidants. In South Kivu Province, Democratic Republic of Congo, two sub-groups of sexual violence survivors completed qualitative interviews, those currently raising a child from an SVRP (parenting group, N = 38) and those who had terminated an SVRP (termination group, N = 17). The findings show that a majority of SVRPs were conceived when participants were held in sexual captivity for prolonged periods of time. The SVRPs were disclosed to friends, family members, other sexual violence survivors, community members, spouses, health care providers, or perpetrators. The confidants were most often chosen because they were perceived by the participants as being discreet, trusted, and supportive. The confidants often provided advice about continuing or terminating the SVRP. Trust and discretion are the most important factors determining to whom women with SVRPs disclose their pregnancies. The vital role of confidants in giving support after disclosure cannot be overlooked. Providing opportunities for survivors to safely disclose their SVRPs, including to health care providers, is a necessary first step in allowing them to access safe and comprehensive post-assault care and services.

Global Emergency Medicine: A Review of the Literature From 2015

OBJECTIVES

The Global Emergency Medicine Literature Review (GEMLR) conducts an annual search of peer-reviewed and gray literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most important new research in this field to a global audience of academics and clinical practitioners.

METHODS

This year 12,435 articles written in six languages were identified by our search. These articles were distributed among 20 reviewers for initial screening based on their relevance to the field of global EM. An additional two reviewers searched the gray literature. A total of 723 articles were deemed appropriate by at least one reviewer and approved by their editor for formal scoring of overall quality and importance. Two independent reviewers scored all articles.

RESULTS

A total of 723 articles met our predetermined inclusion criteria and underwent full review. Sixty percent were categorized as emergency care in resource-limited settings (ECRLS), 17% as EM development (EMD), and 23% as disaster and humanitarian response (DHR). Twenty-four articles received scores of 18.5 or higher out of a maximum score 20 and were selected for formal summary and critique. Inter-rater reliability between reviewers gave an intraclass correlation coefficient of 0.71 (95% confidence interval = 0.66 to 0.75). Studies and reviews with a focus on infectious diseases, trauma, and the diagnosis and treatment of diseases common in resource-limited settings represented the majority of articles selected for final review.

CONCLUSIONS

In 2015, there were almost twice as many articles found by our search compared to the 2014 review. The number of EMD articles increased, while the number ECRLS articles decreased. The number of DHR articles remained stable. As in prior years, the majority of articles focused on infectious diseases.

Stigma and Parenting Children Conceived From Sexual Violence

BACKGROUND AND OBJECTIVES

Since armed conflict began in 1996, widespread sexual violence in eastern Democratic Republic of Congo has resulted in many sexual violence-related pregnancies (SVRPs). However, there are limited data on the relationships between mothers and their children from sexual violence. This study aimed to evaluate the nature and determinants of these maternal-child relationships.

METHODS

Using respondent-driven sampling, 757 women raising children from SVRPs in South Kivu Province, Democratic Republic of Congo were interviewed. A parenting index was created from questions assessing the maternal-child relationship. The influences of social stigma, family and community acceptance, and maternal mental health on the parenting index were assessed in univariate and multivariable analyses.

RESULTS

The majority of mothers reported positive attitudes toward their children from SVRPs. Prevalence of perceived family or community stigma toward the women or their children ranged from 31.8% to 42.9%, and prevalence of perceived family or community acceptance ranged from 45.2% to 73.5%. In multivariable analyses, stigma toward the child, as well as maternal anxiety and depression, were associated with lower parenting indexes, whereas acceptance of the mother or child and presence of a spouse were associated with higher parenting indexes (all P ≤ .01).

CONCLUSIONS

In this study with a large sample size, stigma and mental health disorders negatively influenced parenting attitudes, whereas family and community acceptance were associated with adaptive parenting attitudes. Interventions to reduce stigmatization, augment acceptance, and improve maternal mental health may improve the long-term well-being of mothers and children from SVRPs.

Global emergency medicine: a review of the literature from 2014

OBJECTIVES

The Global Emergency Medicine Literature Review (GEMLR) conducts an annual search of peer-reviewed and gray literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most important new research in this field to a worldwide audience of academics and clinical practitioners.

METHODS

This year 6,376 articles written in six languages were identified by our search. These articles were distributed among 20 reviewers for initial screening based on their relevance to the field of global EM. An additional two reviewers searched the gray literature. A total of 477 articles were deemed appropriate by at least one reviewer and approved by the editor for formal scoring of overall quality and importance.

RESULTS

Of the 477 articles that met our predetermined inclusion criteria, 63% were categorized as emergency care in resource-limited settings, 13% as EM development, and 23% as disaster and humanitarian response. Twenty-five articles received scores of 17.5 or higher and were selected for formal summary and critique. Inter-rater reliability for two reviewers using our scoring system was good, with an intraclass correlation coefficient of 0.657 (95% confidence interval = 0.589 to 0.713). Studies and reviews focusing on infectious diseases, trauma, and the diagnosis and treatment of diseases common in resource-limited settings represented the majority of articles selected for final review.

CONCLUSIONS

In 2014, there were fewer total articles, but a slightly higher absolute number of articles screening in for formal scoring, when compared to the 2013 review. The number of EM development articles decreased, while the number of disaster and humanitarian response articles increased. As in prior years, the majority of articles focused on infectious diseases and trauma.

Respondent-driven sampling to assess mental health outcomes, stigma and acceptance among women raising children born from sexual violence-related pregnancies in eastern Democratic Republic of Congo

OBJECTIVES

Assess mental health outcomes among women raising children from sexual violence-related pregnancies (SVRPs) in eastern Democratic Republic of Congo and stigma toward and acceptance of women and their children.

DESIGN

Participants were recruited using respondent-driven sampling.

SETTING

Bukavu, Democratic Republic of Congo in 2012.

PARTICIPANTS

757 adult women raising children from SVRPs were interviewed. A woman aged 18 and older was eligible for the study if she self-identified as a sexual violence survivor since the start of the conflict (∼1996), conceived an SVRP, delivered a liveborn child and was currently raising the child. A woman was ineligible for the study if the SVRP ended with a spontaneous abortion or fetal demise or the child was not currently living or in the care of the biological mother.

INTERVENTION

Trained female Congolese interviewers verbally administered a quantitative survey after obtaining verbal informed consent.

OUTCOME MEASURES

Symptom criteria for major depressive disorder, post-traumatic stress disorder, anxiety and suicidality were assessed, as well as stigma toward the woman and her child. Acceptance of the woman and child from the spouse, family and community were analysed.

RESULTS

48.6% met symptom criteria for major depressive disorder, 57.9% for post-traumatic stress disorder, 43.3% for anxiety and 34.2% reported suicidality. Women who reported stigma from the community (38.4%) or who reported stigma toward the child from the spouse (42.9%), family (31.8%) or community (38.1%) were significantly more likely to meet symptom criteria for most mental health disorders. Although not statistically significant, participants who reported acceptance and acceptance of their children from the spouse, family and community were less likely to meet symptom criteria.

CONCLUSIONS

Women raising children from SVRPs experience symptoms of mental health disorders. Programming addressing stigma and acceptance following sexual violence may improve mental health outcomes in this population.

Global emergency medicine: a review of the literature from 2013

OBJECTIVES

The Global Emergency Medicine Literature Review (GEMLR) conducts an annual search of peer-reviewed and grey literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most important new research in this field to a worldwide audience of academics and clinical practitioners.

METHODS

This year 8,768 articles written in six languages were identified by our search. These articles were distributed among 22 reviewers for initial screening based on their relevance to the field of global EM. An additional two reviewers searched the grey literature. A total of 434 articles were deemed appropriate by at least one reviewer and approved by an editor for formal scoring of overall quality and importance.

RESULTS

Of the 434 articles that met our predetermined inclusion criteria, 65% were categorized as emergency care in resource-limited settings, 18% as EM development, and 17% as disaster and humanitarian response. A total of 24 articles received scores of 18 or higher and were selected for formal summary and critique. Interrater reliability for two reviewers using our scoring system was good, with an intraclass correlation coefficient of 0.63 (95% confidence interval = 0.55 to 0.69). Infectious diseases, trauma, and the diagnosis and treatment of diseases common in resource-limited settings represented the majority of articles selected for final review.

CONCLUSIONS

In 2013, there were more emergency care in resource-limited settings articles, while the number of disaster and humanitarian response articles decreased, when compared to the 2012 review. However, the distribution of articles selected for full review did not change significantly. As in prior years, the majority of articles focused on infectious diseases, as well as trauma and injury prevention.

A national population-based assessment of 2007-2008 election-related violence in Kenya

Background

Following the contested national elections in 2007, violence occurred throughout Kenya. The objective of this study was to assess the prevalence, characteristics, and health consequences of the 2007–2008 election-related violence.

Methods

A cross-sectional, national, population-based cluster survey of 956 Kenyan adults aged ≥ 18 years was conducted in Kenya in September 2011 utilizing a two-stage 90 x 10 cluster sample design and structured interviews and questionnaires. Prevalence of all forms of violence surrounding the 2007 election period, symptoms of major depressive disorder (MDD) and posttraumatic stress disorder (PTSD), and morbidity related to sexual and physical violence were assessed.

Results

Of 956 households surveyed, 916 households participated (response rate 95.8%). Compared to pre-election, election-related sexual violence incidents/1000 persons/year increased over 60-fold (39.1-2370.1; p < .001) with a concurrent 37-fold increase in opportunistic sexual violence (5.2-183.1; p < .001). Physical and other human rights violations increased 80-fold (25.0-1987.1; p < .001) compared to pre-election. Overall, 50% of households reported at least one physical or sexual violation. Households reporting violence were more likely to report violence among female household members (66.6% vs. 58.1%; p = .04) or among the Luhya ethnic group (17.0% vs. 13.8%; p = 0.03). The most common perpetrators of election-related sexual violence were reported to be affiliated with government or political groups (1670.5 incidents/1000 persons per year); the Kalenjin ethnic group for physical violations (54.6%). Over thirty percent of respondents met MDD and PTSD symptom criteria; however, symptoms of MDD (females, 63.3%; males, 36.7%; p = .01) and suicidal ideation (females, 68.5%; males, 31.5%; p = .04) were more common among females. Substance abuse was more common among males (males, 71.2%; females, 28.8%; p < .001).

Conclusion

On a national level in Kenya, politically-motivated and opportunistic sexual and physical violations were commonly reported among sampled adults with associated health and mental health outcomes.

[Endophthalmitis as a serious complication of intravitreal drug delivery]

BACKGROUND

Endophthalmitis, regarded as a severe complication, can occur after intraocular injection of drugs (IVI). At present only few reports exist on the development of this disease, although recently the number of intraocular injections to treat especially age-related macular degenerations is increasing considerably.

METHODS

In this paper we present our results of a retrospective study of 27 patients suffering from endophthalmitis after IVI. Treatment had been performed between January 2008 and March 2012. The indications for IVI were as follows: age-related macular degeneration 19, venous branch occlusion 1, diabethic retinopathies 6, uveitis 1. The following drugs were injected: bevacizumab in 8, Rranibizumab in 19 patients. The following data were assessed: incubation time, best corrected visual acuity that had been determined before treatment and later 3, 6 and 9 months after therapeutic vitrectomy. Additionally we describe the ophthalmoscopic changes and the results of bacteriological studies.

RESULTS

Endophthalmitis was diagnosed 5.8 days after IVI on average. The vision of all patients had only been hand movements during the first examination. During the observation time the postoperative visual acuity could be improved only to 1/35 on average. During vitrectomy in 24 out of 27 patients a whitish retinal infiltration could be observed. 18 of 27 patients showed a hypopyon during slit lamp examination. 11 patients developed a retinal detachment and one eye had to be enucleated.

CONCLUSIONS

Endophthalmitis must be regarded as a severe complication causing a high risk of retinal detachment with permanent loss of visual acuity. Retinal infiltrations and haemorrhages occur already in the early stages and cause finally a very poor prognosis. The incubation time as a rule amounts to 6 days. The increasing number of IVI and the high risk of damaged retinal structures due to intraocular infections should make postoperative retinal follow-up examinations mandatory, especially during the first 6 days.

Global Emergency Medicine: a review of the literature from 2012

OBJECTIVES

The Global Emergency Medicine Literature Review (GEMLR) conducts an annual search of peer-reviewed and grey literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most important new research in this field to a worldwide audience of academics and clinical practitioners.

METHODS

This year, our search identified 4,818 articles written in six languages. These articles were distributed among 20 reviewers for initial screening based on their relevance to the field of global EM. Two additional reviewers searched and screened the grey literature. A total of 224 articles were deemed appropriate by at least one reviewer and were approved by their editor for formal scoring of overall quality and importance.

RESULTS

Of the 224 articles that met our predetermined inclusion criteria, 56% were categorized as Emergency Care in Resource-limited Settings, 18% as EM development, and 26% as Disaster and Humanitarian Response. A total of 28 articles received scores of 16 or higher and were selected for formal summary and critique. Inter-rater reliability for two reviewers using our scoring system was good, with an intraclass correlation coefficient of 0.625 (95% confidence interval = 0.512 to 0.711).

CONCLUSIONS

In 2012 there were more disaster and humanitarian response articles than in previous years. As in prior years, the majority of articles addressed the acute management of infectious diseases or the care of vulnerable populations such as children and pregnant women.

Militarized sexual violence in South Kivu, Democratic Republic of Congo

Eastern DRC has been the site of a protracted conflict in which sexual violence has been a defining feature. The method used was a retrospective registry-based study of sexual violence survivors presenting to Panzi Hospital between 2004 and 2008. This analysis aimed to describe the patterns of sexual violence described by survivors and to analyze perpetrator profiles. As regards results, a total of 4,311 records were analyzed. Perpetrators in this data set were identified as follows: (a) 6% were civilians; (b) 52% were armed combatants; and (c) 42% were simply identified as "assailant(s)" with no further identifying information. Those identified simply as "assailants" perpetrated patterns of sexual violence that were similar to those of armed combatants, suggesting that this group included a large number of armed combatants. Civilian assailants perpetrated a pattern of sexual violence that was distinct from armed combatants. Conclusions are as follows: These data suggest that a high proportion of sexual assaults in South Kivu are perpetrated by armed combatants. Protection of women in South Kivu will require new strategies that take into account the unique nature of sexual violence in DRC. Engaging with local communities, the UN and other aid organizations is necessary to create new context-appropriate protection programs.

Impact of sexual violence on children in the Eastern Democratic Republic of Congo

The conflict in the Eastern Democratic Republic of Congo (DRC) has been particularly devastating for children and has been typified by high levels of sexual and gender-based violence (SGBV). In this study, we seek to characterize the patterns and impact of sexual violence on children in the Eastern DRC. Semi-structured questionnaires were administered among a convenience sample of women <18 years of age presenting for post-sexual-violence care at Panzi Hospital in South Kivu, DRC. Analysis included quantitative and qualitative methods to describe the characteristics of the violence, perpetrators, and survivors and to illuminate common themes within the narratives. A total of 389 survivors of SGBV under the age of 18 were interviewed between 2004 and 2008. These paediatric survivors were more likely than adult survivors to have experienced gang rape, been attacked by a civilian perpetrator, and been assaulted during the day. Survivor and perpetrator characteristics were further stratified by type of attack. Reports of violence perpetrated by civilians increased 39-fold while reports of violence perpetrated by armed combatants decreased by 70% between 2004 and 2008. Qualitative analysis of the narratives revealed common themes, such as physical signs and symptoms among SGBV survivors (23.9%), pregnancy resulting from rape (19.3%), perpetrators being brought to justice (18.3%), and neighbourhood men as perpetrators (17.7%). Children in the Eastern DRC continue to face significant threats of sexual violence. By understanding the patterns of this violence, local and international approaches could be more effectively implemented to protect these vulnerable children.

Core curricular elements for fellowship training in international emergency medicine

OBJECTIVES

The objective was to describe the common educational goals, curricular elements, and methods of evaluation used in international emergency medicine (IEM) fellowship training programs currently. IEM fellowship programs have been developed to provide formal training for emergency physicians (EPs) interested in pursuing careers in IEM. Those fellowships are variable in scope, objectives, and duration. Previously published articles have suggested a general curriculum structure for IEM fellowships.

METHODS

A search of MEDLINE, EMBASE, and CINAHL databases from 1950 to June 2008 was performed, combining the terms international, emergency medicine, and fellowship. Online curricula and descriptive materials from IEM fellowships listed by the Society for Academic Emergency Medicine (SAEM) were reviewed. Knowledge and skill areas common to multiple programs were organized in discrete categories. IEM fellowship directors were contacted for input and feedback.

RESULTS

Eight articles on IEM fellowships were identified. Two articles described a general structure for fellowship curriculum. Sixteen of 20 IEM fellowship programs had descriptive materials posted online. These information sources, plus input from seven fellowship program directors, yielded the following seven discrete knowledge and skill areas: 1) emergency medicine systems development, 2) humanitarian relief, 3) disaster management, 4) public health, 5) travel and field medicine, 6) program administration, and 7) academic skills.

CONCLUSIONS

While IEM fellowships vary with regard to objectives and structure, this article presents an overview of the current focus of IEM fellowship training curricula that could serve as a resource for IEM curriculum development at individual institutions.

[Report on the patient forum on medical ethics. "Curse and blessing of knowledge of disease"]

From July 15th to July 16th the Protestant Academy of Tutzing opened its doors for the fourth time to the public for a discussion between medical doctors, patients, relatives, nurses and pastors on the new developments of medical diagnosis. The central idea of this type of forum, first initiated in 1993 by Prof. Reiter-Theil, bioethicist at the university of Basel, is to let patients and their relatives actively participate in the bioethical discussion. The dialogue between medical doctor and patient is part of a complex set of interactions between medical progress, ethical aspects and legal regulations. It should be governed by the respect for the autonomy of the patient and by his or her will and capacity to deal with a difficult diagnosis. The communication should be non directive in its nature, but nevertheless take place in an ethically sensitised and responsible manner. As a result counts not what type of message was intended, but what type of message the patient received. The diverse results of the conference can be summarized under the phrase "the patient should determine the rhythm", i. e. the timing and the type of diagnostic knowledge she or he wants to receive.

Noise-induced hearing loss: the effect of melanin in the stria vascularis

Conflicting investigations regarding the potential protective effect of melanin against noise-induced sensorineural hearing loss have suggested that eumelanin and pheomelanin may have differing effects within the stria vascularis. Three strains of C57BL/6J mice, (+/+, a/a) wild-types (dark coats/black eyes), (c2j/c2j, a/a), albinos (white coats/pink eyes), and (+/+, Ay/Ay) yellow mice (yellow coats/black eyes), were subjected to five consecutive days of broad band noise exposure at 112 dB(A) SPL for 3 h/day. Cochlear function was evaluated with auditory brainstem response audiometry to pure tones immediately pre-exposure, 5-6 h postexposure, and 14 days post-exposure. No significant difference in the degree of sensorineural hearing loss induced in the three strains of mice was identified. The eumelanin and pheomelanin content of each stria vascularis and amount of protein per stria for both mouse and guinea pig (2/NCR) were determined via high performance liquid chromatography. No pheomelanin was found in the stria of yellow mice, suggesting that coat color is not an accurate predictor of strial melanin content. The melanin content per mg of strial protein was higher in mice than in guinea pigs. A species-specific difference in melanin content does not explain the absence of a protective effect in mice.

The relative value of fine-needle aspiration and imaging in the preoperative evaluation of parotid masses

BACKGROUND

To establish the sensitivity, specificity, and accuracy of imaging and fine-needle aspiration (FNA), alone or in combination, in distinguishing benign from malignant histologic findings for parotid lesions.

METHODS

Retrospective blinded review of preoperative imaging and FNA studies of parotid masses and comparison with histologic findings after excision.

RESULTS

Forty-eight patients were identified (13 with CT, 35 with MRI); 23 (48%) of the lesions were malignant, 25 (52%) were benign. MRI, CT, and FNA misclassified 17%, 46%, and 21% of the lesions, respectively. The sensitivity/specificity/accuracy of these tests for detecting malignant lesions were as follows: MRI (88%,77%,83%), CT (100%,42%, 69%), and FNA (83%,86%,85%) and were not significantly different. Combinations of imaging and FNA were not significantly better in detecting malignancy.

CONCLUSIONS

Imaging and FNA are comparable in their ability to correctly identify malignant parotid lesions preoperatively. Combining these two modalities yields no advantage in terms of specificity, sensitivity, or accuracy of a malignant diagnosis.

Job hazards for musculoskeletal disorders for youth working on farms

A series of eight focus groups were convened to: (1) identify tasks and activities performed by youth on farms with the potential for causing non-traumatic work-related Musculoskeletal Disorders (MSDs); (2) determine the participants perceptions about risks of MSDs for youths performing those tasks; and (3) determine other factors that might relate to MSDs for youth working on farms, such as possible interventions for prevention. Seventy-two farm family members, 40 adults and 32 farm youth aged 8-18, participated in focus groups. Ten questions were posed to each of the eight groups about what tasks youth perform on the farm, how the work is assigned, and what risk factors are associated with the work. There was general agreement among the adults that maturity rather than age is the dominant factor for determining what tasks are performed by youth workers on the farm. Youth, on the other hand, believed that task urgency dictated what jobs were assigned to youth workers. Most adults indicated that lifting objects, forking, or shoveling was responsible for most of the serious non-traumatic injuries. Bending over while working, sitting in an awkward position looking back at equipment from a tractor, sitting in a cramped position, looking down at a combine header, and long hours of work were also identified as potential problems. Youth described muscle aches and strains of the legs, arms, shoulder, back or neck as everyday occurrences. According to the youth, "If it's not broken, you're fine". Only basic training is provided and most respondents believed that youth learned best through observation. There was general agreement that physician recommended guidelines for assigning youth to tasks would be ignored unless they carried the force of the law.

Improving the precision of primary care physician self-report of antidepressant prescribing

BACKGROUND

Methods to select physicians most likely to benefit from educational interventions to improve the outcome of depression have not been adequately developed.

OBJECTIVE

The purpose of this study was to identify a combination of primary care provider (PCP) self-report questions to improve the precision of PCP estimates of actual antidepressant prescribing as a potential tool for PCP selection.

METHODS

The total number of new and refill antidepressant prescriptions written by 124 PCPs and actually filled at pharmacies over a 2-year period were matched with telephone survey results of these PCPs completed before the 2-year period. Multiple regression techniques were used to identify a set of variables that improved upon PCPs' self-report of prescriptions.

RESULTS

The mean for PCP-reported antidepressant prescriptions written in the last week was 7.8 (+/-11.2). The average weekly prescriptions actually filled was 6.72 (+/-5.65). Most survey variables were significantly correlated with antidepressant prescriptions. The final model included 6 variables that explained 52% of the variance in prescriptions. In addition to PCP-reported number of antidepressants prescribed, average number of primary care patients seen per week and number of patients covered by managed care were directly related to the volume of prescriptions. PCP age, percentage of patients referred immediately without treatment, and mental health services being too far away were inversely related.

CONCLUSIONS

PCP self-reports on antidepressant prescribing are reasonably accurate proxies of actual prescribing. The precision of estimates of actual prescribing can be improved by considering practice structural and financial characteristics.

Bipolar scissors in facial plastic surgery

BACKGROUND

Many methods are available to the facial plastic surgeon for elevating and separating tissue, from cold steel to monopolar cautery to various laser-cutting technologies. Bipolar cautery has replaced monopolar cautery as the optimal hemostatic technique because of its decreased tissue damage and improved capabilities. Bipolar scissors concurrently offer a dissecting technique with hemostatic capability. Little exists in the otolaryngology literature on the use of bipolar scissors for soft tissue dissection.

OBJECTIVE

To describe our experience using bipolar scissors in a variety of facial plastic and reconstructive procedures.

SETTING

Tertiary care referral academic center.

DESIGN

We retrospectively reviewed 78 procedures performed using bipolar scissors between June 1997 and August 1999. In facial plastic cosmetic surgery, bipolar scissors were used 31 times for deep plane face-lifts and 16 times for endoscopic browlifts. In facial plastic reconstructive surgery, bipolar scissors were used in 15 radial forearm free flaps, 10 fibula osteocutaneous flaps, 3 rectus abdominis free flaps, and 3 latissimus dorsi myocutaneous free flaps.

RESULTS

In all procedures, bipolar scissors facilitated the dissection. By allowing for a drier field, less time was required to elevate the flap and obtain hemostasis. Complications were not increased compared with historical controls. In the harvesting of fibula osteocutaneous free flaps, use of bipolar scissors allowed harvesting without use of a tourniquet.

CONCLUSION

Bipolar scissors, a new technology in facial plastic surgery, allow the same control as sharp dissection and provide simultaneous hemostasis.

The need for a system in the care of depression

BACKGROUND

Many problems have been identified in the usual care of patients with depression, including lack of identification, overreliance on medications, and inadequate treatment and follow-up. Most of these problems can be attributed to an absence of depression care systems in primary care practice. We collected information from a group of practices to assess the need for and acceptability of such systems.

METHODS

We conducted 4 focus groups with primary care physicians and their staffs to identify attitudes and perceived behaviors for depression problems and to determine the participants' level of acceptance of alternative systematic approaches. We also surveyed clinicians and a sample of patients who recently visited their practices.

RESULTS

Systematic screening was viewed unfavorably, and many barriers were identified with collaborative care with mental health clinicians. Participants did support involvement of other office staff and more systematic follow-up for patients with depression. The patient survey suggested that some patients with depressive symptoms were unrecognized and undertreated, but the key finding was considerable variation in care among practices.

CONCLUSIONS

These findings suggest that a more systematic approach could improve the problems associated with treatment of patients with depression in primary care and would be acceptable to physicians if introduced appropriately. There are at least 2 promising approaches to introducing such changes. One involves external feedback of data about their care to the practices, followed by offering a variety of systems concepts and tools. The other involves an internal change process in which a multiclinic improvement team collects its own data and develops its own systematic solutions using rapid-cycle testing.

Atherosclerosis-associated changes in the carbohydrate-binding capacities of smooth muscle cells of various human arteries

A set of labelled neoglycoproteins and sulfated polysaccharides, recognizing carbohydrate receptors specific for glucose (glu), mannose (man), lactose (lac), fucose (fuc), fucoidan (fud), dextran sulfate (dex), and heparin (hep), as well as polyclonal antibodies specific for an endogenous beta-galactoside-specific lectin of molecular weight 14kD (A14kD) and a heparin-binding lectin (AHL) have been applied to the main arteries of 10 autopsy cases. Slides of the following types of vessels were incubated with solutions of the biotinylated probes or antibodies at room temperature for 60 min: right and left coronary artery, carotid artery, abdominal and thoracic aorta, pulmonal artery, and the left femoral artery. Atherosclerotic lesions and non-atherosclerotic areas were analyzed for each individual type of vessel. The percentage of the determined expression of the presence of specific binding sites for the various probes was the lowest in the carotid and cardiac arteries, and the highest in the pulmonal artery. Pronounced quantitative differences between the normal and atherosclerotic arterial walls were noted for binding of fuc-, man-, and lac-exposing neoglyco-proteins of the right coronary artery and the carotid artery. Pulmonal and femoral arteries differed with respect to fucoidan or dextran sulfate binding. The heparin-specific lectin and the 14kD-lectin were found to be present in nearly all arterial walls, independent from the localization and the presence of an atherosclerotic lesion. The findings suggest that the expression of sugar receptors, as assessed by labelled neoglycoproteins or sulfated polysaccharides, may be of importance in the development of atherosclerotic lesions in the coronary and carotid arteries.
