In response to increased concerns about emerging infectious diseases, GeoSentinel, the Global Surveillance Network of the International Society of Travel Medicine in partnership with the US Centers for Disease Control and Prevention (CDC), was established in 1995 in order to serve as a global provider-based emerging infections sentinel network, conduct surveillance for travel-related infections and communicate and assist global public health responses. This review summarizes the history, past achievements and future directions of the GeoSentinel Network.

Funded by the US CDC in 1996, GeoSentinel has grown from a group of eight US-based travel and tropical medicine centers to a global network, which currently consists of 68 sites in 28 countries. GeoSentinel has provided important contributions that have enhanced the ability to use destination-specific differences to guide diagnosis and treatment of returning travelers, migrants and refugees. During the last two decades, GeoSentinel has identified a numbermigration-related infectious diseases has been the main focus of GeoSentinel for the last 25 years. However, GeoSentinel is now evolving into a network that will conduct both research and surveillance. The large number of participating sites and excellent geographic coverage for identification of both common and illnesses in individuals who have traversed international borders uniquely position GeoSentinel to make important contributions of travel-related infectious diseases in the years to come.

Typhoid fever in the United States is acquired primarily through international travel by unvaccinated travelers. There is currently no typhoid vaccine licensed in the United States for use in children <2 years.

We reviewed Salmonella enterica serotype Typhi infections reported to the Centers for Disease Control and Prevention (CDC) and antimicrobial-resistance data on Typhi isolates in CDC's National Antimicrobial Resistance Monitoring System from 1999 through 2015.

5131 cases of typhoid fever were diagnosed and 5004 Typhi isolates tested for antimicrobial susceptibility. Among 1992 pediatric typhoid fever patients, 1616 (81%) had traveled internationally within 30 days of illness onset, 1544 (81%) of 1906 were hospitalized (median duration, 6 days; range, 0-50), and none died. Forty percent (799) were <6 years old; 12% were <2 years old. Based on age and travel destination, 1435 (83%) of 1722 pediatric patients were vaccine-eligible; only 68 (5%) of 1361 were known to be vaccinated. Of 2003 iss were unvaccinated, and antimicrobial-resistant infections were common. New public health strategies are needed to improve coverage with currently licensed vaccines. Introduction of an effective pretravel typhoid vaccine for children  less then 2 years could reduce disease burden and prevent drug-resistant infections.

Predicting expected survival time in acutely hospitalised older patients is a clinical challenge.

To examine if activities of daily living (ADL) assessed by Barthel-Index-100 (Barthel-Index) at hospital admission adds useful information to clinicians on expected survival time in older patients.

A nationwide population-based cohort study was used. All patients aged ≥65years in the National Danish Geriatric Database from 2005 to 2014 were followed up until death, emigration or study termination (31 December 2015). Individual data were linked to national health registers. Barthel-Index was categorised into five-point subcategories with a separate category of Barthel-Index = 0. Kaplan-Meier analysis was used to assess crude survival proportions (95% CI) and Cox regression to examine association of Barthel-Index and mortality adjusting for age, Charlson comorbidity index, medication use, BMI, marital status, prior hospitalisations and admission year.

In total, 74,589 patients (63% women) aged (mean (SD)) 8clinicians on expected survival time in patients admitted to a geriatric department.Contractures can complicate burn recovery. There are limited studies examining the prevalence of contractures following burns in pediatrics. This study investigates contracture outcomes by location, injury, severity, length of stay, and developmental stage. Data were obtained from the Burn Model System between 1994 and 2003. All patients younger than the age of 18 with at least one joint contracture at hospital discharge were included. Sixteen areas of impaired movement from the shoulder, elbow, wrist, hand, hip, knee, and ankle joints were examined. Analysis of variance was used to assess the association between contracture severity, burn size, and length of stay. Age groupings were evaluated for developmental patterns. A P value of less than .05 was considered statistically significant. Data from 225 patients yielded 1597 contractures (758 in the hand) with a mean of 7.1 contractures (median 4) per patient. Mean contracture severity ranged from 17% (elbow extension) to 41% (ankle plantarflexion) loss of movement. Statistically significant associations were found between active range of motion loss and burn size, length of stay, and age groupings. The data illustrate quantitative assessment of burn contractures in pediatric patients at discharge in a multicenter database. find more Size of injury correlates with range of motion loss for many joint motions, reflecting the anticipated morbidity of contracture for pediatric burn survivors. These results serve as a potential reference for range of motion outcomes in the pediatric burn population, which could serve as a comparison for local practices, quality improvement measures, and future research.

The epidemiology of acute bacterial meningitis has changed substantially since the introduction of conjugate vaccines.

We analysed nationwide surveillance data of all cerebrospinal fluid isolates received from 1988 to 2019 in the Netherlands. We assessed the impact of conjugate vaccines on incidence (defined as episodes per 100,000 population per year) and for different age groups using incidence rate ratios (IRR), comparing incidence before and after conjugate vaccine introduction.

We analysed 17,393 episodes of which 5,960 episodes (34%) occurred in pre-school children (3 months-4 years). Overall, bacterial meningitis incidence decreased from 6.37 to 1.58 between 1989-1993 and 2014-2019 (IRR 0.25 [95%CI 0.23-0.26], p<0.001), and was most pronounced in pre-school and school-aged children (5-15 years; IRR 0.10 [95%CI 0.09-0.12] and 0.08 [95%CI 0.06-0.10], both p<0.001). The incidence was highest in young infants (<90 days) due to a high incidence of group B streptococcus and Escherichia coli meningitis (42.48 and 19.49). Conjugate vaccines effectively reduced the incidence of Haemophilus influenzae type b, Neisseria meningitidis serogroup C, and 10 pneumococcal serotypes (IRR 0.02-0.04, p<0.001). At the end of the observed period, Streptococcus pneumoniae caused the majority of meningitis cases (829/1,616 [51%]), mostly in older adults (45-64 years) and elderly (65+ years; incidence 1.06 and 1.54, respectively).

Conjugate vaccines reduced the burden of bacterial meningitis, especially in children. The efforts for new measures to prevent bacterial meningitis should be focused on neonates and elderly, as the residual rate of disease is still high in these age groups.

Traditional capture-mark-recapture methods can be costly, time-consuming, and invasive. Photographic mark-recapture (PMR) is a cost-effective, minimally invasive way to study population dynamics in species with distinct markings or color patterns. We tested the feasibility and the application of PMR using the software Hotspotter to identify Nicrophorus spp. from digital images of naturally occurring spot patterns on their elytra. We conducted a laboratory study evaluating the identification success of Hotspotter on Nicrophorus americanus (Olivier, 1790) and Nicrophorus orbicollis (Say, 1825) before implementation of a mark-recapture study in situ. We compared the performance of Hotspotter using both 'high-quality' and 'low-quality' photographs. For high-quality photographs, Hotspotter had a false rejection rate of 2.7-3.0% for laboratory-reared individuals and 3.9% for wild-caught individuals. For low-quality photographs, the false rejection rate was much higher, 48.8-53.3% for laboratory-reared individuals and 28.3% for wild-caught individuals. We subsequently analyzed encounter histories of wild-caught individuals with closed population models in Program MARK to estimate population abundance. In our study, we demonstrated the utility of using PMR in estimating population abundance for Nicrophorus spp. based on elytral spot patterns.

Whole Slide Imaging (WSI) is an alternative method to light microscopy (LM). However, few studies have compared the diagnostic agreement between WSI and LM, especially to grade oral epithelial dysplasia (OED). The purpose of this study was to evaluate the variability in grading OED by the World Health Organization grading system, using WSI and conventional LM, and to investigate whether the access to clinical information, and psychologic or physical states of the pathologists could interfere with the diagnosis.

eleven experienced pathologists from seven Brazilian universities independently evaluated twenty-five OED cases. The analyses were performed in duplicate for each method, with an interval of at least 30 days, and the time consumed in each analysis was measured. Physical and psychologic states were evaluated by blood pressure levels, heart rate and two questionnaires State-Trait Anxiety Inventory and Perceived Stress Scale. Clinical information was provided after the second evaluation using WSI and the pathologist could change their diagnostic decision or not.

LM showed a higher inter-examiner agreement (k=0.53) than WSI (k=0.45) and a smaller time consumed by the pathologists (mean of 65.53 seconds compared to 91.02 seconds in WSI). In the first analysis using conventional microscopy, there was a positive correlation between kappa values and anxiety (r=0.47, p=0.02), and stress (r=0.64, p<0.01), and an inverse correlation with heart rate (r=-0.48, p=0.02). In the digital analysis, there was also a positive correlation between kappa values and anxiety (r=0.75, p<0.001). After clinical information was given, there was a slight change in 11.3% of the cases, and a great discrepancy in 1.1% of the cases, mainly increasing the OED grade.

both microscopy systems had similar results, although LM had slightly higher kappa values, and WSI was more time consuming.

Oral microorganisms produce damage through the transfer to bloodstream, colonizing other tissues or direct damage in the oral cavity. Aim to study the quantitative interactions between C. albicans and the mutans streptococci and ms serotypes in the saliva of the oral cavity of patients with Down syndrome (DS).

Included 120 patients of both genders, 60 patients with Down syndrome (DS) and 60 pa- tients as a control group (CG). Samples of saliva were taken, and bacteria and fungi were grown on TYCSB and Saboureaud agar. Microbiological, serological and quantitative analyses were performed to determine the kind of isolated of microorganisms corresponding to the ms c, e, f and k for species S. mutans and d and g for S. sobrinus and C. albicans. Electronic scanning microscopy was employed to visualize and confirm the colonies under study. Statistics analysis included t-test proofs for matched data test, Scheffé and ANOVA.

Forming units (CFU) per mL of saliva of C. albicans a significant difference was observed among DS<CG groups.
