Chromobacterium haemolyticum infection from hot springs near Yellowstone National Park: a case report

BACKGROUND

Chromobacterium haemolyticum is a gram-negative anaerobic sporulated rod and was only first identified in 2008. It is very rare in people with only a handful of cases having been diagnosed around the world.

CASE PRESENTATION

After suffering a fall near Yellowstone National Park, a white male patient in his 50 s presented to a hospital in Eastern Idaho. With many unexplained symptoms, several changes in patient stability and recovery, over a course of 18 days in the hospital, the infecting organism could not be easily identified. Labs in the hospital, state, and eventually outside of the state were consulted for pathogen identification, which was only accomplished after the patient was discharged.

CONCLUSIONS

To our knowledge, this is only the seven reported human infection with Chromobacterium haemolyticum. This bacterium is difficult to identify and may be occur in rural areas without the proper testing facilities to quickly identify the pathogen, which is essential to timely treatment.

Impact Evaluation of a Resident-Driven Research Training Workshop in Idaho: A Feasibility Study

Objectives

Engagement in research activities is a critical component of clinical residency training. It is vital to build research capacity of residents to help interpret evidence-based medicine and design quality improvement projects. A mixed methods study was conducted to assess the impact of a 1-day research training workshop conducted at Eastern Idaho Regional Medical Centre, Idaho in May 2022. The workshop was targeted to improve the research knowledge of current clinical residents of Internal Medicine and Family Medicine.

Methods

Workshop comprised of expert presentations, with assessment of difference in knowledge with a pretest and post-test. The sessions were organized around the core competencies of Institute of Medicine. Suggestions were also gathered from the audience. A pretest and post-test based on 13 questions was administered to the participants to assess change in research-related knowledge. Comments and suggestions of the participants were also recorded. Wilcoxon rank test was applied to determine statistical difference across each question and cumulative knowledge score. Conventional content analysis was applied to explore the comments and feedback.

Results

The mean score of participants improved across all 12 questions. Statistically significant results were observed for the questions about types of studies qualifying as qualitative research. The cumulative score of participants increased in the post-test from 8.57 to 9.35. The participants gained new knowledge (94.3%), and felt more comfortable in application of research methods (74.3%). Encouraging feedback was obtained from the audience. They stated that they had benefited from the workshop and felt more prepared and motivated to indulge in scholarly activities.

Conclusion

The study shows improvement in research-related knowledge of clinical residents attending a 1-day training workshop. We recommend inclusion of such workshops in the curriculum of residents for skill building and enhanced indulgence in research activities in order to prepare them as future leaders in quality improvement, health policy, and hospital administration.

The Development and Evaluation of a National School-based HIV Prevention Intervention for Primary School Children in Kenya

Primary schools in Kenya provide a promising venue for widespread delivery of HIV prevention interventions. This article describes the development and evaluation of Making Life's Responsible Choices (MLRC), a school-based HIV prevention intervention for primary school children developed through a collaborative global partnership involving multiple community stakeholders. Intervention development was informed by extensive reviews of youth-focused evidence-based HIV prevention interventions, and was rooted in both the Theory of Planned Behavior and Social Cognitive Theory. MLRC includes six modules: 1) self-awareness, 2) human sexuality, 3) healthy relationships, 4) drug/alcohol abuse, 5) HIV/AIDS and other sexually transmitted infections, and 6) behavior change. Class 5 pupils (N=1846; 52.1% girls, 47.9% boys; mean age = 12) attending 46 different Catholic-sponsored public and private primary schools throughout Kenya participated in the evaluation of the intervention program which was delivered in the classroom and occurred over the course of 40 weeks (one academic term). Changes in knowledge and behavioral intentions were assessed using a one-group pre-test post-test experimental design. Pupils completed module-specific assessment measures, and paired samples t-tests were used to compare changes in knowledge and behavioral intentions at the classroom level. Gender-specific analyses were also conducted. All six modules displayed statistically significant positive changes in the mean percentage of knowledge items answered correctly for the full sample, with marginal gender differences revealed. Statistically significant health-promoting changes were seen in 11 of the 18 behavioral intention items (3 per module), with gender differences also revealed. Findings suggest that implementing interventions such as MLRC has the potential to thwart the spread of HIV among youth in Kenya, and equip youth with health-promoting skills. In addition, school-based programs have the potential to become institutionalized in school settings in order to maintain their long-term sustainability.

A Hazard Analysis of Risk Factors of Mortality in Individuals Who Inject Drugs in Denver CO

Despite multiple risk factors for mortality among People Who Inject Drugs (PWID), more research is warranted that examines sub-populations within PWID. Mortality data from PWID participating in longitudinal HIV prevention research in Denver were obtained from The Colorado Department of Public Health and Environment. Risk factors for both all-cause and acute-toxicity related mortality were analyzed using Cox proportional hazards regression. Two-thousand seven individuals were interviewed at baseline. Eighty-six individuals died during the time frame of the study, 58 of which were due to acute-toxicity. Disabled (HR = 3.3, p < 0.001), gay/lesbian-identified (HR = 2.6, p = 0.03), white race/ethnicity (HR = 2.4, p = 0.003), and use of a shared cooker (HR = 2.1, p = 0.01) were important adjusted risk factors. These suggest that drug and HIV interventions should utilize techniques that can address the needs of marginalized populations in addition to HIV drug risk behaviors.

Public Health Effects of Medical Marijuana Legalization in Colorado

INTRODUCTION

The public health consequences of the legalization of marijuana, whether for medical or recreational purposes, are little understood. Despite this, numerous states are considering medical or recreational legalization. In the context of abrupt changes in marijuana policy in 2009 in Colorado, the authors sought to investigate corresponding changes in marijuana-related public health indicators.

METHODS

This observational, ecologic study used an interrupted time-series analysis to identify changes in public health indicators potentially related to broad policy changes that occurred in 2009. This was records-based research from the state of Colorado and Denver metropolitan area. Data were collected to examine frequency and trends of marijuana-related outcomes in hospital discharges and poison center calls between time periods before and after 2009 and adjusted for population. Analyses were conducted in 2014.

RESULTS

Hospital discharges coded as marijuana-dependent increased 1% per month (95% CI=0.8, 1.1, p<0.001) from 2007 to 2013. A change in trend was detected in poison center calls mentioning marijuana (p<0.01). After 2009, poison center calls increased 0.8% per month (95% CI=0.2, 1.4, p<0.01). Poison center calls also increased 56% (95% CI=49%, 63%, p<0.001) in the period following the policy change. Further, there was one hospital discharge coded as dependent for every 3,159 (95% CI=2465, 3853, p<0.001) medical marijuana registrant applications.

CONCLUSIONS

The abrupt nature of these changes suggests public health effects related to broad policy changes associated with marijuana. This report may be used to assist in policy decisions regarding the short-term public health effects of marijuana legalization.

Get Yourself Tested 2011–2012: Findings and prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae at an urban public health system

During April 2011 and April 2012 the Get Yourself Tested campaign was launched throughout the Cook County Health and Hospitals System to promote testing of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) among 15–25-year-olds in a high-prevalence urban community. Retrospective data were collected and analysed. Demographic differences by CT and GC positivity were evaluated along with factors associated with CT and GC status. A total of 2853 tests were conducted among individuals aged 15–25 years. A total of 2060 (72%) females and 793 (28%) males were tested. Of those tested, 488 (17%) individuals tested positive for either CT or GC or both; 400 (14%) were positive for CT, 139 (5%) were positive for GC. The prevalence for GC was 8.8% ( n = 70) in males compared to 3.3% ( n = 69) in females ( p < 0.001) and the prevalence of CT was 16% ( n = 127) for males compared to 13.3% ( n = 273) for females ( p = 0.057). Women in a high-risk population are more likely to get tested for sexually transmitted infections; however, men are more likely to test positive for CT and GC. Get Yourself Tested is an important campaign to encourage wider spread testing among populations at risk in Cook County.
