For each example, the analysis of the exon mapping in homologous proteins supports the conservation of their exon patterns. We propose that when a clear-cut relationship between exon and structural boundaries can be identified, it is possible to infer a specific "evolutionary pattern" which may improve TRPs detection and classification.Our institution has performed microbiological diagnosis of Tropheryma whipplei since 2001, initially with a PCR targeting 16S rRNA before the development of a quantitative PCR in 2012. Here we report the clinical characteristics of a cohort of patients suffering from Whipple disease (WD) and evaluate the impact of these molecular techniques. Patients with a positive PCR for T. whipplei between 2001 and 2016 were retrospectively collected from microbiological databases. Two infectious diseases specialists reviewed their medical records and classified them as definite WD, probable WD or carriage of T. whipplei without disease. A total of 1153 samples were tested for T. whipplei; 76 samples taken from 36 patients were positive. Fifteen were considered as presenting a definite WD, seven as a probable WD and 14 as carriers. Median age was 56.4 years (extremes, 6.6-76.1). Median time from symptoms to diagnosis was 3 years (2.5 months to 13.3 years). About 60% were immunosuppressed. The most frequent clinical presentations were joint pain (16/22), weight loss (15/22) and/or digestive tract disorder (15/22); 41% had neurological manifestations, 32% pulmonary involvement and 32% lymphadenopathies. Bacterial load in faeces or saliva were 88 425 copies/mL (IQR 6175-292 725) in definite and probable WD and 311 copies/mL (IQR 253-2090) in carriers, respectively. We observed a 90% PPV above 32 200 copies/mL in faeces. WD is a chronic multisystemic disease with frequent pulmonary involvement. Underlying immunodeficiency is commonly observed leading to more complex clinical presentation. Positive T. whipplei PCR in both stool and saliva has a high positive predictive value. Moreover, patients with WD present higher bacterial load in faeces with a threshold of >32 200 copies/mL predicting ongoing infection.
Community-acquired pneumonia (CAP) is a frequently occurring disease linked to high mortality and morbidity. Previous studies indicated that the administration of antibiotics within 4hrs of admission can improve key patient outcomes associated with CAP, such as mortality and time to clinical stability. However, the results have been heterogeneous and may not be applicable to all healthcare settings. Therefore, we designed a cohort study to estimate the impact of timely antibiotic administration on outcomes in patients admitted with CAP.
The impact of antibiotic administration within 4hrs of admission and other covariates were estimated for 30-day mortality, stability within 72hrs, 30-day readmission and time to discharge, using multivariable regression models. Sensitivity analyses were performed on a subset of patients with the most severe CAP and a propensity score matched cohort.
In total, 2264 patients were included. Of these, 273 (12.1%) died within 30days of admission, 1277 (56.4%) were alive and s triaged and prioritized according to age, comorbidities, clinical condition and pneumonia severity.
Exploring fever aetiologies improves patient management. Most febrile adults are outpatients, but all previous studies were conducted in inpatients. This study describes the spectrum of diseases in adults attending outpatient clinics in urban Tanzania.
We recruited consecutive adults with temperature ≥38°C in a prospective cohort study. We collected medical history and performed a clinical examination. selleck We performed 27364 microbiological diagnostic tests (rapid tests, serologies, cultures and molecular analyses) for a large range of pathogens on blood and nasopharyngeal samples. We based our diagnosis on predefined clinical and microbiological criteria.
Of 519 individuals, 469 (89%) had a clinically or microbiologically documented infection and 128 (25%) were human immunodeficiency virus (HIV) -infected. We identified 643 diagnoses 264 (41%) acute respiratory infections (36 (5.6%) pneumonia, 39 (6.1%) tuberculosis), 71 (11%) infections with another focus (31 (4.8%) gastrointestinal, 26 (4.0%) urogenital,biotics. Systematic HIV screening is essential to appropriately manage febrile patients.
Protection induced by acellular vaccines can be short, requiring novel immunization strategies. Objectives of this study were to evaluate safety and capacity of a recombinant pertussis toxin (PTgen) -coated Viaskin® epicutaneous patch to recall memory responses in healthy adults.
This double-blind, placebo-controlled randomized trial (Phase I) assessed the safety and immunogenicity of PTgen administered on days 0 and 14 to healthy adults using Viaskin® patches applied directly or after epidermal laser-based skin preparation. Patch administration was followed by Boostrix®dTpa on day 42. Antibodies were assessed at days 0, 14, 28, 42 and 70.
Among 102 volunteers enrolled, 80 received Viaskin-PT (Viaskin-PT 25 μg (n=25), Viaskin-PT 50 μg (n=25), laser+Viaskin-PT 25 μg (n=5), laser+Viaskin-PT 50 μg (n=25)), Viaskin-placebo (n=10) or laser+Viaskin-placebo (n=2). Incidence of adverse events was similar across groups (any local event 21/25 (84.0%), 24/25 (96.0%), 4/5 (80.0%), 24/25 (96.0%), 8/10 (80.0%), 10/12 study is registered at ClinicalTrials.gov (NCT03035370) and was funded by DBV Technologies.Mutations in DDX3X have recently been identified as a common cause of intellectual disability and congenital anomalies. DDX3X (Xp11.4) encodes the DEAD box RNA helicase that plays an important role in gene regulation, apoptosis, and oncogenesis. Here, we report a case of 6-year-old Japanese girl with a novel variant (NM_001193416.3 c.1574A > G; p.(Tyr525Cys), who exhibited psychomotor retardation, severe constipation, and a recurrent paralytic ileus. This is the second report of severe gastrointestinal symptoms being associated with this disease. This report expands the phenotype caused by DDX3X variants and reveals an important clinical aspect for patients and medical staff.
