Development and assessment of a low literacy, pictographic asthma action plan with clinical automation to enhance guideline-concordant care for children with asthma.

OBJECTIVE: Asthma is characterized by reversible pulmonary symptoms, frequent hospitalizations, poor quality of life, and varied treatment. Parents with low health literacy (HL) is linked to poor asthma outcomes in children. Recent practice updates recommended inhaled corticosteroids for the management of persistent asthma, but guideline-concordant care is suboptimal. Our aim was to develop and assess an Asthma Action Plan (AAP) that could serve as an individualized plan for low HL families and facilitate guideline-concordant care for clinicians. METHODS: We followed the National Institute of Health 5-step "Clear & Simple" approach to develop the Uniformed Services AAP. Our AAP included symptom pictographs (dyspnea, cough, sleep, activity) and guideline-concordant clinical automation tools. Caregivers assessed the pictograms for validity (transparency of ≥ 85%; translucency score ≥ 5; and ≥ 85% recall). Readability was assessed using 7 formulas. (<6th Grade was acceptable). Comprehensibility, design quality, and usefulness was assessed by caregivers using the Consumer Information Rating Form (CIRF) (>80% was acceptable). Understandability and actionability was assessed by medical librarians using the Patient Education Materials Assessment Tool-Printable (>80% was acceptable). Suitability was assessed by clinicians using the modified Suitability Assessment of Materials (SAM) instrument (>70% was superior). RESULTS: All 12 pictograms were validated (N = 118 respondents). Readability demonstrated a 4th grade level. Overall CIRF percentile score = 80.4%. Understandability and Actionability = 100%. Suitability score = 75%. CONCLUSIONS: Our AAP was formally endorsed by the Allergy & Asthma Network. The Uniformed Services AAP is a novel tool with embedded clinical automation that can address low HL and enhance guideline-concordant care.

ATS core curriculum 2023. Pediatric pulmonary medicine: Respiratory disorders in infants.

The American Thoracic Society Core Curriculum updates clinicians annually in pediatric pulmonary disease. This is a summary of the Pediatric Pulmonary Medicine Core Curriculum presented at the 2023 American Thoracic Society International Conference. The respiratory disorders of infancy discussed in this year's review include: the care of the patient with bronchopulmonary dysplasia in the neonatal intensive care unit, clinical phenotypes and comorbidities; diffuse lung disease; pulmonary hypertension; central and obstructive sleep apnea. The care of infants with respiratory disorders often poses significant challenges to the general pediatric pulmonologist, sleep clinician, and neonatologist. This review aims to highlight the most clinically relevant aspects of the evaluation, management, and outcomes of infants with these key respiratory disorders, while emphasizing the importance of multidisciplinary care. Furthermore, this document summarizes essential aspects of genetic testing, novel imaging and treatment modalities, and includes multiple resources for clinical practice.

ATS Core Curriculum 2022. Pediatric Pulmonary Medicine: Updates in pediatric neuromuscular disease.

The American Thoracic Society Core Curriculum updates clinicians annually in pediatric pulmonary disease. This is a concise review of the Pediatric Pulmonary Medicine Core Curriculum presented at the 2022 American Thoracic Society International Conference. Neuromuscular diseases (NMD) comprise a variety of conditions that commonly affect the respiratory system and cause significant morbidity including dysphagia, chronic respiratory failure, and sleep disordered breathing. Respiratory failure is the most common cause of mortality in this population. Substantial progress has been made in diagnosis, monitoring and treatment for NMD over the last decade. Pulmonary function testing (PFT) is utilized to objectively measure respiratory pump function and PFT milestones are utilized in NMD-specific pulmonary care guidelines. New disease modifying therapies are approved for the treatment of patients with Duchenne muscular dystrophy and spinal muscular atrophy (SMA), including the first ever approved systemic gene therapy, in the case of SMA. Despite extraordinary progress in the medical management of NMD, little is known regarding the respiratory implications and long-term outcomes for patients in the era of advanced therapeutics and precision medicine. The combination of technological and biomedical advancements has increased the complexity of the medical decision-making process for patients and families, thus emphasizing the importance of balancing respect for autonomy with the other foundational principles of medical ethics. This review features an overview of PFT, noninvasive ventilation strategies, novel and developing therapies, as well as the ethical considerations specific to the management of patients with pediatric NMD.

Cystic Fibrosis Foundation otolaryngology care multidisciplinary consensus recommendations.

BACKGROUND: Cystic fibrosis (CF) is a multisystem disease that often requires otolaryngology care. Individuals with CF commonly have chronic rhinosinusitis but also present with hearing loss and dysphonia. Given these manifestations of CF, otolaryngologists are frequently involved in the care of patients with CF; however, there is limited consensus on optimal management of sinonasal, otologic, and laryngologic symptoms. METHODS: The Cystic Fibrosis Foundation convened a multidisciplinary team of otolaryngologists, pulmonologists, audiologists, pharmacists, a social worker, a nurse coordinator, a respiratory therapist, two adults with CF, and a caregiver of a child with CF to develop consensus recommendations. Workgroups developed draft recommendation statements based on a systematic literature review, and a ≥80% consensus was required for acceptance of each recommendation statement. RESULTS: The committee voted on 25 statements. Eleven statements were adopted recommending a treatment or intervention, while five statements were formulated recommending against a specific treatment or intervention. The committee recommended eight statements as an option for select patients in certain circumstances, and one statement did not reach consensus. CONCLUSION: These multidisciplinary consensus recommendations will help providers navigate decisions related to otolaryngology consultation, medical and surgical management of CF-CRS, hearing, and voice in individuals with CF. A collaborative and multidisciplinary approach is advocated to best care for our patients with CF. Future clinical research is needed utilizing standardized, validated outcomes with comprehensive reporting of patient outcome, effects of modulator therapies, and genetic characteristics to help continue to advance care, decrease morbidity, and improve the quality of life for individuals with CF.

ATS Core Curriculum 2021. Pediatric Pulmonary Medicine: Pulmonary Infections.

The following is a concise review of the Pediatric Pulmonary Medicine Core reviewing pediatric pulmonary infections, diagnostic assays, and imaging techniques presented at the 2021 American Thoracic Society Core Curriculum. Molecular methods have revolutionized microbiology. We highlight the need to collect appropriate samples for detection of specific pathogens or for panels and understand the limitations of the assays. Considerable progress has been made in imaging modalities for detecting pediatric pulmonary infections. Specifically, lung ultrasound and lung magnetic resonance imaging are promising radiation-free diagnostic tools, with results comparable with their radiation-exposing counterparts, for the evaluation and management of pulmonary infections. Clinicians caring for children with pulmonary disease should ensure that patients at risk for nontuberculous mycobacteria disease are identified and receive appropriate nontuberculous mycobacteria screening, monitoring, and treatment. Children with coronavirus disease (COVID-19) typically present with mild symptoms, but some may develop severe disease. Treatment is mainly supportive care, and most patients make a full recovery. Anticipatory guidance and appropriate counseling from pediatricians on social distancing and diagnostic testing remain vital to curbing the pandemic. The pediatric immunocompromised patient is at risk for invasive and opportunistic pulmonary infections. Prompt recognition of predisposing risk factors, combined with knowledge of clinical characteristics of microbial pathogens, can assist in the diagnosis and treatment of specific bacterial, viral, or fungal diseases.

ATS Core Curriculum 2020. Pediatric Pulmonary Medicine.

The American Thoracic Society Core Curriculum updates clinicians annually in adult and pediatric pulmonary disease, medical critical care, and sleep medicine, in a 3- to 4-year recurring cycle of topics. These topics will be presented at the 2020 International Conference. Below is the pediatric pulmonary medicine core, including pediatric hypoxemic respiratory failure; modalities in noninvasive management of chronic respiratory failure in childhood; surgical and nonsurgical management of congenital lung malformations; an update on smoke inhalation lung injury; an update on vaporizers, e-cigarettes, and other electronic delivery systems; pulmonary complications of sarcoidosis; pulmonary complications of congenital heart disease; and updates on the management of congenital diaphragmatic hernia.

EpiNATO-2: Enhancing Situational Awareness and Overall Force Health Protection While Deployed in the Combined Joint NATO Environment: Describing the Identified 2016 Q Fever Outbreak in Kosovo Force (KFOR).

EpiNATO-2 is the only interoperable health surveillance system that is defined in North Atlantic Treaty Organization (NATO) doctrine. It was first implemented in the Kosovo Force and European Union Training Mission Mali in 2013. EpiNATO-2 is mandated for use during all NATO operations. Its coverage has steadily increased and now includes all NATO Joint and Component Command Operations and several non-NATO operations. The system monitors morbidity predominately for Role 1 sites by using weekly reports from the medics and other medical providers. The reports for all sites in theater are sent to the Combined Joint Medical (CJMED), which consolidates and submits them to NATO Deployment Health Surveillance Capability (DHSC), the satellite branch of NATO Centre of Excellence for Military Medicine (MILMED COE), for analysis and feedback. Although EpiNATO-2 will likely have a number of overlaps with most nations' disease and nonbattle injury trackers, a distinguishing characteristic is that it has specific categories for classifying more clinical activity. Sustaining the quality of data collection is paramount and achieved through contemporaneous analysis and feedback that are disseminated via CJMED to all providers. This enhances situational awareness about evolving trends in health issues across the deployed force and is intended to provide information for action and medical decision-making and force health protection assurance at the local and theater levels. The awareness imparted by this article can add to the Special Operations Forces (SOF) medics' tool kit to ensure success for the SOF medic and SOF community while deployed or collaborating with NATO and NATO partner nation militaries at any level in theater.

NATO Military Medical Exercise Vigorous Warrior 2017.

Our intent in presenting this information is to increase the awareness of the Special Operations Forces (SOF) medical community and the overall international medical/military communities about the North Atlantic Treaty Organization (NATO) military medicine's premiere Vigorous Warrior Exercises organized by NATO Centre of Excellence for Military Medicine (MILMED COE). The Vigorous Warrior medical exercise series is conducted biennially, with four successful iterations since 2011. These international medical exercises engage military medical elements that enhance NATO capabilities and ensure that new NATO medical concepts are being exercised and tested across the full capability-requirement spectrum. The primary aims of these exercises are to provide NATO and partner nations a multipurpose platform to collectively train their medical forces and personnel; test and experiment new concepts and doctrines; medically evaluate national or multinational medical treatment facilities in accordance with NATO doctrine; produce medical lessons identified and lessons learned; and provide the participants with multinational experience to enhance the provision of health care in NATO operations. These exercises directly strengthen partnerships, improve military medical interoperability, and demonstrate the Alliance's commitment to improving international military collaboration. More than 1,000 medical personnel from 26 NATO and partner nations successfully conducted the joint, multilevel, multinational, medical live exercise Vigorous Warrior 2017 (VW17) throughout three locations in Germany during 4-22 September 2017. This article details the highly successful VW17 and paves the way for a very bright future for the Alliance's military medicine as well as a Vigorous Warrior 2019.

Clinical utility of the bispectral index score when compared to the University of Michigan Sedation Scale in assessing the depth of outpatient pediatric sedation.

This single blinded observational study compared the bispectral index (BIS) monitor with a validated pediatric sedation scale, the University of Michigan Sedation Scale (UMSS), to evaluate whether the BIS score can be used to judge the depth of sedation in pediatric outpatients. Thirty-eight children, with a mean age of 5.8 years, undergoing routine sedation for both noninvasive and gastrointestinal procedures, had simultaneous BIS and UMSS scores recorded. Sedation categories were defined as light, moderate, and deep for both UMSS and BIS. There was a moderate correlation between BIS and the UMSS, Spearman's r < -0.499. The correlation was poor for children receiving chloral hydrate, r < -0.213. The BIS score was not predictive of any specific UMSS score. The UMSS and BIS categories of sedation matched only 36% of the time. BIS underestimated the clinical level of sedation.

Surveillance for Ehrlichia canis, Anaplasma phagocytophilum, Borrelia burgdorferi, and Dirofilaria immitis in Dogs From Three Cities in Colombia.

OBJECTIVE: Emerging infectious and zoonotic diseases are made up in large proportion by vector-borne diseases (VBD). Dogs are parasitized by disease vectors such as ticks and mosquitoes, making dogs adequate reservoirs for zoonoses. Risk of exposure to VBD exists for the U.S. military personnel and Military Working Dogs (MWD) when deployed globally. The importance of canine VBD surveillance relates to veterinary and public health significance for the host nations as well as for the U.S. troops and MWDs. The objective of this work was to survey dogs from the cities of Medellin, Barranquilla, and Cartagena in Colombia to determine the prevalence of heartworm disease (Dirofilaria immitis), ehrlichiosis (Ehrlichia canis), Lyme disease (Borrelia burgdorferi), and anaplasmosis (Anaplasma phagocytophilum). METHODS: Canine (n=498) blood samples (1? 3 mL) were collected during July 2011 from Medellin (n=175), Barranquilla (n=223), and Cartagena (n=100) and were tested on-site using IDEXX SNAP? 4Dx? Test Kits. RESULTS: The overall combined sample prevalence of E. canis, A. phagocytophilum, D. immitis, and B. burgdorferi was 62%, 33%, 1.6%, and 0%, respectively. In Medellin, 26% of the samples were positive for E. canis, 12% for A. phagocytophilum, and 0% for D. immitis. In Barranquilla, sample prevalence for E. canis, A. phagocytophilum, and D. immitis was 83%, 40%, and 2%, respectively. In Cartagena, E. canis, A. phagocytophilum, and D. immitis prevalence was 80%, 51%, and 3%, respectively. CONCLUSION: E. canis and A. phagocytophilum are present in all three surveyed cities. There is a higher sample prevalence for E. canis and A. phagocytophilum than for D. immitis. In addition, the prevalence for these organisms is higher in Barranquilla and Cartagena than in Medellin. Overall, this study emphasizes the value of surveillance for VBDs in order to determine disease prevalence, develop risk assessments, and implement control measures.

Point prevalence survey for tick-borne pathogens in military working dogs, shelter animals, and pet populations in northern Colombia.

BACKGROUND: Based on the high tick-borne pathogen results from a 2011 surveillance study in three Colombian cities, an in-depth point prevalence survey was conducted to determine the seroprevalence of tick-borne pathogens at a specific point in time in 70 working dogs, 101 shelter dogs, and 47 client-owned dogs in Barranquilla, Colombia. RESULTS: Of the 218 serum samples, 163 (74%) were positive for Ehrlichia canis and 116 (53%) for Anaplasma platys. Exposure to tick-borne pathogens was highest in shelter and working dogs where more than 90% of the samples were seropositive or positive on polymerase chain reaction for one or more organisms as compared to 51% in client-owned animals. CONCLUSION: Surveillance for exposure to tick-borne pathogens provides vital information necessary to protect and conserve the health of local humans and animals, deployed military service members, and working dogs in various parts of the world. This study and resultant data demonstrate the value of following a broad-based surveillance study with a more specific, focused analysis in an area of concern. This area?s high levels of exposure warrant emphasis by medical planners and advisors on precautionary measures for military dogs, Special Operations Forces personnel, and the local public.

Vector-borne disease surveillance in puerto rico: pathogen prevalence rates in canines ? Implications for public health and the u.s. Military ? Applying the one health concept.

Vector-borne diseases (VBDs) make up a large number of emerging infectious and zoonotic diseases. Vectors such as ticks, fleas, and mosquitoes parasitize dogs, thus making canine populations adequate reservoirs for infectious disease and zoonoses. The U.S. military deploys its personnel and Military Working Dogs (MWDs) throughout the world with possible risk of exposure to VBDs. Canine VBDs continue to have veterinary and public health significance for the host nations as well as for deployed U.S. personnel and MWDs. Thus, ongoing and consistent disease surveillance is an essential component to preserve health. The purpose of this study was to survey dogs from multiple cities and varying regions throughout Puerto Rico to determine the prevalence of ehrlichiosis (Ehrlichia canis), anaplasmosis (Anaplasma phagocytophilum), Lyme disease (Borrelia burgdorferi), and heartworm disease (Dirofilaria immitis) from May to July 2012. Canine blood samples (1?3 ml) from the cities of San Juan (n = 629), Guaynabo (n = 50), Ponce (n = 20) and Vieques Island (n = 53) were obtained and tested on-site using an IDEXX SNAP? 4Dx? (enzyme-linked immunosorbent assay) test kit. Prevalence for single or multiple disease status was calculated for each site. The overall period prevalence of VBD in Puerto Rico in the shelter population was 57.7% (71/123). In Guaynabo, the VBD prevalence was 30% (15/50); 2 (13%) of these positive dogs had VBD co-infection. In the coastal port city of Ponce, it was 60% (12/20); 6 (50%) dogs were infected by two or more VBDs. On Vieques Island, it was 83% (44/53); 27 (61%) dogs were coinfected. Conversely, samples collected at the Fort Buchanan Veterinary Clinic in the capitol city of San Juan resulted in a VBD prevalence of 8.9% (56/629). Lyme disease was not detected in any sample. This study showed the presence of D. immitis, E. canis, and A. phagocytophilum in all four sites of Puerto Rico, emphasizing the value of surveillance for VBDs to determine disease prevalence, complete risk assessments, and impleme t timely preventive medicine and other preventive measures. The lower VBD prevalence rate in the canine samples from Fort Buchanan demonstrates the value of responsible pet ownership and importance of preventive medicine and public health.

Impact of cilia ultrastructural examination on the diagnosis of primary ciliary dyskinesia.

Ultrastructural examination of cilia is the "gold standard" for diagnosing primary ciliary dyskinesia. There is little evidence suggesting the most effective method of procuring a ciliary biopsy and scant benchmark data on rates of conclusive biopsies or on the diagnostic impact of such biopsies. To critically assess rates of inconclusive, positive, and negative ciliary biopsies and to identify clinical factors associated with conclusive results, we reviewed ciliary biopsies submitted for electron microscopy from 2006 to 2011, noting whether specimens were adequate for analysis and whether the ciliary structure was normal. The biopsy site, method used, procedurist's specialty, and clinical diagnoses were determined. Biopsy findings were categorized by diagnostic impact. Over 5 years, 187 patients had 211 biopsies. Conclusive results were obtained on 133/211 biopsies (63%); the remainder were insufficient. The rate of inconclusive biopsies did not vary significantly (P > 0.05; Fisher's exact) among sampling methods. Abnormal results were identified in 8/133 (6.0%) of the adequate specimens. Forceps compared to brush biopsies (abnormal in 4/12 versus 4/121 of the adequate specimens, P  =  0.002), along with multiple biopsy samples (taken on same or different days) compared with a single biopsy sample (abnormal in 3/12 versus 1/110 of the adequate specimens, P  =  0.01), were more likely to yield an abnormal result. Only 63% of pediatric ciliary biopsies provide adequate morphology for analysis, the large majority of these samples showing normal ciliary anatomy. The method of obtaining biopsies did not significantly affect result conclusiveness. Understanding the diagnostic impact of ultrastructural analysis is important as new diagnostic algorithms are developed for primary ciliary dyskinesia.

Surveillance of zoonotic and infectious diseases in Ecuador: implications for special operations forces medical operations, personnel, and canines.

Vector-borne diseases (VBD) make up a large number of emerging infectious and zoonotic diseases. Ticks, fleas, and mosquitoes are effective vectors parasitizing canines, making dogs adequate reservoirs for zoonoses. The U.S. military deploys personnel and government-owned animals around the world with possible risk of exposure to VBD. Canine VBD have veterinary and public health significance for the host nations as well as for the U.S. troops and its working animals deployed in the theater of operations. These factors make disease surveillance a great importance. The objective of this work was to survey canines from the cities of Manta and Guayaquil in Ecuador to determine prevalence of heartworm disease (D. immitis), ehrlichi os is (E. canis), Lyme disease (B. burgdorf eri), and anapl asmosis (A. phagocytophilum). Canine blood samples (1-3ml) collected from the cities of Manta (n=50) and Guayaquil (n=50) were tested on site using a SNAPR 4DxR Test Kit. Prevalence for single or multiple disease status was calculated for each city. In the city of Manta the overall prevalence of diseases was 78%; 52% for E. canis alone, and 26% for co-infection with E. canis and A. phagocytophilum. The overall prevalence for the city of Guayaquil was 88%; 40% for E. canis alone, 22% for A. phagocytophilum alone, and 26% for co-infection with E. canis and A. phagocytophilum. Neither heartworm disease nor Lyme disease was detected in any samp le. In conclusion, this study showed the extensive presence of E. canis and A. phagocytophilum in both cities in Ecuador, emphasizing the value of surveillance for zoonotic diseases to determine disease prevalence and risk assessments, as well as to implement control measures.

Zoonotic and infectious disease surveillance in Central America: Honduran feral cats positive for toxoplasma, trypanosoma, leishmania, rickettsia, and Lyme disease.

A recent zoonotic and infectious disease field surveillance study in Honduras resulted in the discovery of Toxoplasma, Trypanosoma, Leishmania, Rickettsia, and Lyme disease with statistically high prevalence rates in a group of feral cats. All five diseases--Toxoplasmosis, Trypanosomiasis, Leishmaniasis, Rickettsiosis, and Lyme disease--were confirmed in this group of cats having close contact to local civilians and U.S. personnel. These diseases are infectious to other animals and are known to infect humans as well. In the austere Central and South American sites that Special Operations Forces (SOF) medics are deployed, the living conditions and close quarters are prime environments for the potential spread of infectious and zoonotic disease. This study?s findings, as with previous veterinary disease surveillance studies, emphasize the critical need for continual and aggressive surveillance for zoonotic and infectious disease present within animals in specific areas of operation (AO). The importance to SOF is that a variety of animals may be sentinels, hosts, or direct transmitters of disease to civilians and service members. These studies are value-added tools to the U.S. military, specifically to a deploying or already deployed unit. The SOF medic must ensure that this value-added asset is utilized and that the findings are applied to assure Operational Detachment-Alpha (SFOD-A) health and, on a bigger scale, U.S. military force health protection and local civilian health.

Scapula fracture secondary to static line injury in a 22 year-old active duty soldier.

This radiological case study of scapula fracture is reported in a 22 year-old active duty male Soldier who sustained a static line injury during an airborne operation at Fort Bragg, North Carolina. This is the first reported scapula fracture secondary to this mechanism since a 1973 report by Heckman and Levine. The fracture was neither identified by Emergency Department nor Orthopedic Surgery providers, and was reported in the radiologist?s formal read. Ten emergency physicians and emergency medicine physician assistants reviewed the radiographical studies and none successfully identified the injury. Because this injury was uniformly missed by experienced emergency medicine providers it is presented as a radiographic case study in hopes that this injury will not go undiagnosed, potentially causing increased morbidity and mortality in this patient population. The patient was treated with a posterior splint and immobilization and seen by the orthopedic service the next day. Interestingly, the orthopedic surgeon also did not recognize this fracture. This mechanism of injury is rarely seen in clinical practice outside of the airborne community. Scapula fractures can be an indicator of serious thoracic trauma and may prompt the need for further diagnostic studies. The fact that so many providers missed the injury reinforces the need to evaluate the patient as a whole and to be ever suspicious of missing concomitant injuries in the trauma patient.

Public health foodborne illness case study during a Special Operations Forces deployment to South America.

UNLABELLED: Although many public health articles have been published detailing foodborne illness outbreaks, a medical literature search revealed no articles that detail a case study or a specific response of a deployed U.S. military unit to a potential foodborne illness. This article describes a recent public health case study of a U.S. Special Operations Forces (SOF) team sickened while deployed to South America. It highlights public health factors which may affect U.S. personnel deployed or serving overseas and may serve as a guide for a deployed SOF medic to reference in response to a potential food- or waterborne illness outbreak. METHODS: Eight food samples and five water samples were collected. The food samples were obtained from the host nation kitchen that provided food to the SOF team. The water samples were collected from the kitchen as well as from multiple sites on the host nation base. These samples were packaged in sterile containers, stored at appropriate temperatures, and submitted to a U.S. Army diagnostic laboratory for analysis. RESULTS: Laboratory results confirmed the presence of elevated aerobic plate counts (APCs) in the food prepared by the host nation and consumed by the SOF team. DISCUSSION: High APCs in food are the primary indicator of improper sanitation of food preparation surfaces and utensils. CONCLUSION: This case study concluded that poor kitchen sanitation, improper food storage, preparation, and/or holding were the probable conditions that led to the team?s symptoms. These results emphasize the importance of ensuring safe food and water for U.S. personnel serving overseas, especially in a deployment or combat setting. Contaminated food and/or water will negatively impact the health and availability of forces, which may lead to mission failure. The SOF medic must respond to potential outbreaks and be able to (1) critically inspect food preparation areas and accurately advise commanders in order to correct deficiencies and (2) perform food/water surveillance testing consistently throughout a deployment and at any time in response to a potential outbreak.

Monitoreo de Ehrlichia canis, Anaplasma phagocytophilum, Borreliaburgdorferi, y Dirofilaria immitis en perros de tres ciudades enColombia / Surveillance for Ehrlichia canis, Anaplasma phagocytophilum, Borreliaburgdorferi, and Dirofilaria immitis in Dogs From Three Cities in Colombia

Emerging infectious and zoonotic diseases are made up in large proportion by vector-borne diseases (VBD). Dogs are parasitized by disease vectors such as ticks and mosquitoes, making dogs adequate reservoirs for zoonoses. Risk of exposure to VBD exists for the US military personnel and Military Working Dogs (MWD) when deployed globally. The importance of canine VBD surveillance relates to veterinary and public health significance for the host nations as well as for the US troops and MWDs. The objective of this work was to survey dogs from the cities of Medellin, Barranquilla, and Cartagena in Colombia to determine prevalence of heartworm disease (Dirofilaria immitis), ehrlichiosis (Ehrlichia canis), Lyme disease (Borrelia burgdorferi), and anaplasmosis (Anaplasma phagocytophilum). Canine (n=498) blood samples (1-3cc) were collected during July 2011 from Medellin (n=175), Barranquilla (n=223), and Cartagena (n=100). Samples were tested on-site using IDEXX SNAP® 4Dx® Test Kits. The overall combined sample prevalence of E. canis, A. phagocytophilum, D. immitis, and B. burgdorferi was 62%, 33%, 1.6%, and 0%. In Medellin, 26% of the samples were positive for E. canis, 12% for A. phagocytophilum, and 0% for D. immitis. In Barranquilla, sample prevalence for E. canis, A. phagocytophilum, and D. immitis were 83%, 40%, and 2%. In Cartagena, E. canis, A. phagocytophilum, and D. immitis sample prevalence were 80%, 51%, and 3%. In conclusion, E. canis and A. phagocytophilum are present in all three surveyed cities. There is a higher prevalence for E. canis and A. phagocytophilum than D. immitis. In addition, the prevalence for these organisms is higher in Barranquilla and Cartagena than in Medellin. Overall, this study emphasizes the value of surveillance for VBDs in order to determine disease prevalence, develop risk assessments, and to implement control measures.

Las nuevas enfermedades infecciosas y enfermedades zoonóticas son en su mayor proporción el resultado o causa de enfermedades transmitidas por vectores (VBD: Vector-Borne Diseases). Perros que han sido infectados por enfermedades vectores como mosquitos y garrapatas, se convierten en fuentes adecuadas para enfermedades zoonóticas. Existe un riesgo ante la exposición a VBD en el personal de las Fuerzas Armadas Americanas y los perros del servicio militar (MWD: Military Working Dogs) cuando estos se encuentran trabajando fuera de los Estados Unidos. Tanto como para la Veterinaria, la Salud pública de las Naciones anfitrionas y de las Fuerzas Armadas Americanas y de sus perros militares es de gran importancia el seguimiento y vigilancia de VBD en los perros. El objetivo de este trabajo fué el monitoreo e investigación de perros en las ciudades de Medellin, Barranquilla y Cartagena en Colombia y determinar la existencia de enfermedades como la enfermedad del gusano del corazón ("heartworm disease" -Dirofilaria immitis), ehrlichiosis (Ehrlichia canis), Lyme disease (Borrelia burgdorferi) y anaplasmosis (Anaplasma phagocytophilum). Perros (n=498) muestras de sangre (1-3cc) recolectadas durante Julio 2011. En Medellín (n=175) Barranquilla (n= 223) y Cartagena (n= 100). Muestras fueron utilizadas en sitio por medio de IDEXX SNAP® 4Dx® Test Kits. La convinación total de las pruebas muestran una prevalencia de E. canis, A.phagocytophilum, D. immitis, y B. burgdorferi fue de un 62%, 33%, 1.6% y de un 0% En Medellin, 26% de las pruebas fueron positivas para E. canis, 12% para A. phagocytophilum, y 0% para D. immitis. En Barranquilla, las muestras demostraron una prevalencia para E. canis, A. phagocytophilum y D. immitis fue de un 83%, 40% y 2%. En Cartagena, E. canis, A. phagocytophilum, y D. immitis mostraron una prevalencia del 80%, 51% y 3%. En conclusión, E. canis y A. phagocytophilum estan presentes en las tres ciudades. Hay una mayor prevalencia para E. canis y A. phagocytophilum y también la presencia de estos organismos es mayor en Barranquilla y Cartagena comparado con los resultados de Medellín. Este estudio tiene como propósito enfatizar el valor e importancia del monitoreo y estudio de VBDs con el fin de determinar la prevalencia de las enfermedades, el desarrollo de sus causas y determinar medios para prevenir y controlar el esparcimiento de estas enfermedades.
