Transstadial transmission of tick-borne rickettsiae has been well documented. Few studies, however, have evaluated the role of transovarial transmission of tick-borne rickettsiae, particularly in nature within the host-vector ecosystem. This cross-sectional study aimed to understand the role of transovarial transmission of tick-borne rickettsiae among feeding ticks at different life stages. Tick eggs laid by engorged wild-caught adult female ticks were pooled and tested for Rickettsia spp. and Anaplasma/Ehrlichia spp. using molecular techniques, while adult fed ticks were tested individually. Additionally, larval and nymphal ticks were collected in the wild from small mammals, pooled and tested for Rickettsia spp. and Anaplasma/Ehrlichia spp. There were 38 fed adult and 618 larvae/nymphs (60 pools total) Dermacentor spp. ticks collected from livestock and rodents. All individual adult ticks and tick pools were positive for Rickettsia spp. While none of the larvae/nymphs were positive for Anaplasma/Ehrlichia spp., two adult fed ticks were positive. Rickettsia spp. DNA was detected in 91% (30/33) of the pooled eggs tested, and one pool of eggs tested positive for Anaplasma/Ehrlichia spp. Sequencing data revealed Rickettsia spp. shared ≥99% identity with R. raoultii ompA. Anaplasma/Ehrlichia spp. shared ≥89% identity with A. ovis 16S ribosomal RNA. This study identified potential transovarial transmission of Rickettsia spp. and Anaplasma spp. among D. nuttalli ticks. Additional studies are needed to further assess the proportion of transovarial transmission occurring in nature to better understand the burden and disease ecology of tick-borne rickettsiae in Mongolia.
Natural disasters significantly contribute to human death and suffering. Moreover, they exacerbate pre-existing health inequalities by imposing an additional burden on the most vulnerable populations. Robust local health systems can greatly mitigate this burden by absorbing the extraordinary patient volume and case complexity immediately after a disaster. This resilience is largely determined by the predisaster local surgical capacity, with trauma, neurosurgical, obstetrical and anaesthesia care of particular importance. Nevertheless, the disaster management and global surgery communities have not coordinated the development of surgical systems in low/middle-income countries (LMIC) with disaster resilience in mind. Herein, we argue that an appropriate peridisaster response requires coordinated surgical and disaster policy, as only local surgical systems can provide adequate disaster care in LMICs.We highlight three opportunities to help guide this policy collaboration. First, the Lancet Commission on Global Surgery and the Sendai Framework for Disaster Risk Reduction set forth independent roadmaps for global surgical care and disaster risk reduction; however, ultimately both advocate for health system strengthening in LMICs. Second, the integration of surgical and disaster planning is necessary. Disaster risk reduction plans could recognise the role of surgical systems in disaster preparedness more explicitly and pre-emptively identify deficiencies in surgical systems. Based on these insights, National Surgical, Obstetric, and Anesthesia Plans, in turn, can better address deficiencies in systems and ensure increased disaster resilience. Lastly, the recent momentum for national surgical planning in LMICs represents a political window for the integration of surgical policy and disaster risk reduction strategies.
Background: There is a lack of evidence on the clinical management of patients who have suffered human trafficking. Synthesizing the evidence from similar patient populations may provide valuable insight. This review summarizes findings on therapeutic interventions for survivors of sexual assault and intimate partner violence (IPV). Method: We conducted two systematic reviews using the MEDLINE database. We included only randomized controlled trials of therapies with primary outcomes related to health for survivors of sexual assault and IPV. For the sexual assault review, there were 78 abstracts identified, 16 full-text articles reviewed, and 10 studies included. For the IPV review, there were 261 abstracts identified, 24 full-text articles reviewed, and 17 studies included. Analysis compared study size, intervention type, patient population, primary health outcomes, and treatment effect. Results: Although our search included physical and mental health outcomes, almost all the studies meeting inclusion and exclusion criteria focused on mental health. The interventions for sexual assault included spiritually focused group therapy, interference control training, image rehearsal therapy, sexual revictimization prevention, educational videos, cognitive behavioral therapy, and exposure therapy. The interventions in the IPV review included group social support therapy, exposure therapy, empowerment sessions, physician counseling, stress management programs, forgiveness therapy, motivational interviewing, and interpersonal psychotherapy. Conclusions: Insights from these reviews included the importance of culturally specific group therapy, the central role of survivor empowerment, and the overwhelming focus on mental health. These key features provide guidance for the development of interventions to improve the health of human trafficking survivors.
Strong surgical systems are necessary to prevent premature death and avoidable disability from surgical conditions. The epidemiological transition, which has led to a rising burden of non-communicable diseases and injuries worldwide, will increase the demand for surgical assessment and care as a definitive healthcare intervention. Yet, 5 billion people lack access to timely, affordable and safe surgical and anaesthesia care, with the unmet demand affecting predominantly low-income and middle-income countries (LMICs). Rapid surgical care scale-up is required in LMICs to strengthen health system capabilities, but adequate financing for this expansion is lacking. This article explores the critical role of innovative financing in scaling up surgical care in LMICs. We locate surgical system financing by using a modified fiscal space analysis. Through an analysis of published studies and case studies on recent trends in the financing of global health systems, we provide a conceptual framework that could assist policy-makers in health systems to develop innovative financing strategies to mobilise additional investments for scale-up of surgical care in LMICs. This is the first time such an analysis has been applied to the funding of surgical care. Innovative financing in global surgery is an untapped potential funding source for expanding fiscal space for health systems and financing scale-up of surgical care in LMICs.
Research into prevention of cardiovascular disease has increasingly focused on mobile health (mHealth) technologies and their efficacy in helping individuals adhere to heart-healthy recommendations, including daily physical activity levels. By including the use of mHealth technologies in the discussion of physical activity recommendations, clinicians empower patients to play an active daily role in modifying their cardiovascular risk-factor profile. In this review, we critically evaluate the mHealth and physical activity literature to determine how these tools may lower cardiovascular risk while providing real-time tracking, feedback, and motivation on physical activity levels. We analyze the various domains-including user knowledge, social support, behavioral change theory, and self-motivation-that potentially influence the effectiveness of smartphone applications to impact individual physical activity levels. In doing so, we hope to provide a thorough overview of the mHealth landscape, in addition to highlighting many of the administrative, reimbursement, and patient-privacy challenges of using these technologies in patient care. Finally, we propose a behavioral change model and checklist for clinicians to assist patients in utilizing mHealth technology to best achieve meaningful changes in daily physical activity levels.
Twenty‐six per cent of Mongolians live pastoral lifestyles, increasing their likelihood of exposure to ticks and placing them at a higher risk for contracting tick‐borne diseases (TBDs). Anaplasma spp. and Rickettsia spp. have been identified in ticks, livestock and humans in Mongolia, but no known qualitative research has been conducted investigating the association between nomadic herder characteristics, tick bite history and exposure to TBDs. To better understand the association between self‐reported tick bites and symptoms versus actual exposure to TBDs, this study paired serological data with 335 surveys administered to Mongolian herders, ages 12–69, from 2014 to 2015. Logistic regression results identified no significant associations between reported tick bites or symptoms with serological evidence of Anaplasma spp. and Rickettsia spp. controlling for age, gender and aimag. Among the 335 respondents who were seropositive to either Anaplasma spp. or Rickettsia spp., 32.9% self‐reported experiencing abnormal symptoms such as redness, inflammation, headache, arthritis or fever after being bitten. Alternatively, 17.3% (58/335) of individuals reported experiencing symptoms following a tick bite in instances where serological results indicated no exposure to Anaplasma spp. or Rickettsia spp. Results also identified inconsistencies in reporting and seroprevalence among different age groups, with children having the highest reporting and treatment seeking rates but low levels of exposure in comparison with other groups. While survey results showed that individuals were aware of peak tick seasons and tick species that inhabit specific areas, 58% of heads of households (49/84) were unaware that ticks can cause disease in livestock or dogs. This study suggests that herders are an at‐risk population in Mongolia with gaps in awareness of TBD risk. Increased surveillance paired with focused outreach to prevent TBDs targeted to the herder population is encouraged.
