Detection of Foodborne Pathogens in Acute Gastroenteritis Patient's Stool Samples Using the BioFire® FilmArray® Gastrointestinal PCR Panel in the Republic of Trinidad and Tobago, West Indies.

In 2009, the burden of illness study for acute gastroenteritis in Trinidad and Tobago highlighted that ~10% of stool samples tested were positive for a foodborne pathogen. The study also noted that limited laboratory screening for pathogens contributed to a lack of etiology as public health hospitals only routinely tested for Salmonella and Shigella, and sometimes for Escherichia coli and Campylobacter. To better understand the foodborne pathogens responsible for acute gastroenteritis, enhanced testing using the BioFire® FilmArray® Gastrointestinal PCR panel was used to screen diarrheal stool samples for 22 pathogens from patients in 2018. The five general public health hospitals (San Fernando, Mt. Hope, Port of Spain, Sangre Grande, and Tobago) were notified of research activities and diarrheal stool samples were collected from all acute gastroenteritis patients. A total of 66 stools were screened and ~30% of samples tested positive for a foodborne pathogen. The current study showed that a much wider range of enteric pathogens were associated with acute gastroenteritis in Trinidad and Tobago than previously reported in 2009. These findings can be used by health officials to guide appropriate interventions, as well as to provide evidence for adoption of the PCR panel detection method at public health hospitals to benefit patient care.

Detecting bone lesions in the emergency room with medical infrared thermography.

INTRODUCTION: Low- to high-energy impact trauma may cause from small fissures up to extended bone losses, which can be classified as closed or opened injuries (when they are visible at a naked eye). OBJECTIVE: The aim of this study was to investigate the feasibility of clinical diagnosis of bone trauma through medical infrared thermography, in a hospital emergency room. METHODS: Forty-five patients with suspected diagnosis of bone fracture were evaluated by means of medical infrared images, and the data correlated with the gold standard radiographic images, in the anteroposterior, lateral, and oblique views, at the orthopedic emergency department. The control group consisted of thermal images of the contralateral reference limb of the volunteers themselves. Data were acquired with a medical grade infrared camera in the regions of interest (ROIs) of leg, hand, forearm, clavicle, foot, and ankle. RESULTS: In all patients evaluated with a diagnosis of bone fracture, the mean temperature of the affected limb showed a positive difference greater than 0.9 °C (towards the contralateral), indicating the exact location of the bone trauma according, while the areas diagnosed with reduced blood supply, showed a mean temperature with a negative variation. CONCLUSION: Clinical evaluation using infrared imaging indicates a high applicability potential as a tool to support quick diagnosis of bone fractures in patients with acute orthopedic trauma in an emergency medical setting. The thermal results showed important physiological data related to vascularization of the bone fracture and areas adjacent to the trauma well correlated to radiographic examinations.

Mycobacterial Growth Inhibition Assay (MGIA) as a Host Directed Diagnostic Tool for the Evaluation of the Immune Response in Subjects Living With Type 2 Diabetes Mellitus.

The lack of efficient and cost-effective diagnostic tools contributes to poor control of tuberculosis in endemic countries. Moreover, host biological processes influence susceptibility, and infection resolution. It is well known that comorbidities such as type 2 diabetes mellitus (DM2) affect the host immune response, making individuals more susceptible to Mycobacterium tuberculosis infection. Currently, there are no laboratory tools that can identify those subjects who have a higher risk of developing the disease. In this study, we used a whole blood mycobacterial growth inhibition assay to assess the immune response capacity to inhibit mycobacterial growth between healthy subjects and those living with DM2 with optimal and poor glycemic control. We also measured cytokine levels in the culture supernatant by cytokine bead arrays. We included 89 patients with DM2: 54 patients with optimal control (mean age 56.2 ± 11.75 years) and 35 patients with poor control (mean age 52.05 ± 9.94 years). We also included 44 healthy subjects as controls (mean age 42.12 ± 11.75 years). We compared the Δlog UFC (a value that represents the difference between mycobacterial growth in the control tube versus the subject's blood) between each group. Our results demonstrate that patients with DM2 had a lower capacity to inhibit M. tuberculosis growth (Δlog UFC DM2 subjects 0.9581 (-0.3897 to 2.495) vs Δlog UFC healthy subjects 0.7190 (-0.2678 to 2.098); p=0.013). Comparing subjects living with DM2 (optimal and poor glycemic control) vs healthy subjects, we found only significant differences between healthy subjects and patients poorly controlled (Δlog UFC optimal control group 0.876 (-0.3897 to 2.495); Δlog UFC poor control group 1.078 (0.068 to 2.33); Δlog UFC healthy subjects 0.7190 (-0.2678 to 2.098); p= 0.022). Therefore, glycemic control assessed by glycosylated hemoglobin values influences the capacity of the host to control the infection. Our results confirm that the whole blood mycobacterial growth inhibition assay has potential utility as an in vitro marker of M. tuberculosis immunological control in vivo in subjects living with DM2. This assay can be used to evaluate the immune response of each individual against M. tuberculosis, allowing clinicians to choose a more specific host-directed therapy.

Assessment of DNA Integrity From Trap-Captured Boll Weevil (Coleoptera: Curculionidae) for Use in a New PCR-Based Diagnostic Tool.

The boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), is a major pest of commercial cotton (Gossypium hirsutum) in the southern United States and throughout Central and South America. Efforts are underway to develop a PCR-based diagnostic tool that can be used to rapidly and accurately differentiate boll weevils from other weevil species that are commonly captured in pheromone traps. However, the quantity and integrity of weevil DNA must be sufficient for a successful PCR assay. Currently, active eradication programs service traps weekly, but post-eradication programs service traps at 2- or 3-wk intervals. Consequently, captured weevils may be dead, dismembered, and exposed to environmental conditions for prolonged periods which may adversely affect the quantity and quality of weevil DNA. We documented DNA quantity and integrity in boll weevils and weevil body parts aged in traps over a 3-wk period under field conditions. The quantity of DNA extracted from whole weevils, heads, abdomens, and legs generally remained sufficient (> 1 ng/µl) for successful PCR amplification throughout the 21-d period. The integrity (fragment length) of extracted DNA declined over time but generally was sufficient (> 700 bp) for successful amplification. PCR amplification of three marker genes validated that the quality and integrity of DNA extracted from dead weevils and individual weevil body parts aged in traps up to 21 d remained at sufficient levels for the PCR-based assay. However, our data also suggested that rain events may accelerate degradation of weevil DNA.

Reconstruction of Panoramic Dental Images Through Bézier Function Optimization.

Computed tomography (CT) and X-ray images have been extensively used as a valuable diagnostic tool in dentistry for surgical planning and treatment. Nowadays, dental cone beam CT has been extensively used in dental clinics. Therefore, it is possible to employ three-dimensional (3D) data from the CT to reconstruct a two-dimensional (2D) panoramic dental image that provides a longitudinal view of the mandibular region of the patient, avoiding an additional exposure to X-ray. In this work, we developed a new automatic method for reconstructing 2D panoramic images of the dental arch based on 3D CT images, using Bézier curves and optimization techniques. The proposed method was applied to five patients, some of them with missing teeth, and smooth panoramic images with good contrast were obtained.

The different tests for the diagnosis of COVID-19 - A review in Brazil so far.

SARS-CoV-2 is a novel virus from the coronavirus family that emerged in the end of December 2019 in Wuhan, China. The virus is now widespread and causing the current pandemic of COVID-19, a highly pathogenic viral pneumonia, commonly presented with fever and cough, which frequently lead to lower respiratory tract disease with poor clinical outcomes associated with older age and underlying health conditions. Supportive care for patients is typically the standard protocol because no specific effective antiviral therapies have been identified so far. The current outbreak is challenging governments and health authorities all over the world. In here we present a comparison among the current diagnostic tools and kits being used to test Brazilian population.

Loop-Mediated Isothermal Amplification Combined with PCR for Rapid Identification of the Ethiopian Fruit Fly (Diptera: Tephritidae).

Nowadays, with increasing trend of trans-boundary transportation of agricultural products and higher probability of introduction of many invasive species into new areas, fast and precise species diagnosis is of great significance particularly at the port of entry, where morphological identification often requires adult insect specimens especially with specialist insects. The cucumber fruit fly, Dacus ciliatus Loew (Diptera: Tephritidae), ranks as one of the most destructive agricultural pests attacking mainly fruits of Cucurbitaceae. This pest is also widespread and highly invasive; thus, it is a high priority for pest detection and quarantine programs. Although cucumber fruit fly adults can usually be identified and distinguished from the other species by morphological keys, it is often difficult or impossible to distinguish this species from the other tephritids that share host plants by using material from other stages of development. In such situations, using a quick and robust alternative species diagnostic tool would be valuable. In this study, we assessed a technique combining loop-mediated isothermal amplification (LAMP) with PCR (PCR-LAMP) for the rapid detection and discrimination of cucumber fruit fly DNA from some other common tephritid species attacking Cucurbitaceae, using material from different stages of development. The described method was species-specific and sensitive and provided a rapid diagnostic tool to detect D. ciliaus even by non-experts.

Prevalence of Pediatric Asthma Risk in Santo Domingo, Dominican Republic.

BACKGROUND: Early detection and treatment of pediatric asthma could reduce morbidity and lessen burden on society. Currently there is no known research on the prevalence of pediatric asthma in the Dominican Republic (DR) and no known asthma risk assessment tool for one-time encounters in a fast-paced clinic. OBJECTIVES: To pilot a streamlined version of previously validated screening tools to estimate the prevalence of pediatric asthma risk in Santo Domingo Norte, DR. METHODS: A combined asthma questionnaire and clinical assessment tool was developed and administered to patients aged 2-12 years. FINDINGS: We found that 25.7% of the 74 study participants were categorized as probable asthma, 21.6% were at high risk for asthma, 14.9% elevated risk, and 37.8% not at risk. CONCLUSION: If the prevalence of 25.7% is representative of the DR as a whole, the DR would have one of the highest national rates in Latin America. The study assessment tool was convenient to use, but tool validation is needed.

Infrared Thermography in Dogs with Mammary Tumors and Healthy Dogs.

BACKGROUND: Infrared thermography is a painless, noninvasive, nonionizing diagnostic imaging exam used in human medicine as an auxiliary tool for breast cancer diagnosis in women. HYPOTHESIS/OBJECTIVES: Define thermographic mean temperatures of healthy mammary glands and compare these temperatures with those of mammary glands with tumors in dogs. ANIMALS: Fifty client-owned female dogs were evaluated, including 20 with histopathologically confirmed mammary tumor and 30 clinically healthy (control). METHODS: A randomized study using infrared thermography analyzed each mammary gland of the animals from the control group and mammary glands with tumors from the tumor group, then the thermographic temperatures obtained were compared. Thermographic exam was performed in a temperature-controlled room with a cooled thermographic camera-Flir E-40 (Flir Systems(®) ) RESULTS: There was significantly a higher temperature in the caudal abdominal and inguinal mammary glands than the other glands in the healthy group (P < .05). Dogs with mammary tumors had significantly higher thermographic temperature compared with unaffected glands regardless of the tumor size and the location (P < .05). CONCLUSIONS AND CLINICAL IMPORTANCE: The technique seems to be able to assess for the presence of neoplasia within the mammary tissue in bitches. Further investigation is necessary to determine the impact of this technique when adopted clinically.
