Clinical characteristics of patients with mpox infection in the United Arab Emirates: a prospective cohort study.

Objectives: The study aims to explore the risk factors, clinical characteristics, and outcomes of mpox infection in Abu Dhabi, United Arab Emirates (UAE).

Methods: A prospective cohort study was conducted at two communicable disease centers in Abu Dhabi, UAE and patients admitted with confirmed mpox infections between May 01, 2022 and December 31, 2022 were included in our study.

Results: A total of 176 mpox patients were admitted, of which 93% (n = 164) were men and mean age was 30.

Effectiveness of BBIBP-CorV vaccine against severe outcomes of COVID-19 in Abu Dhabi, United Arab Emirates.

The effectiveness of the inactivated BBIBP-CorV vaccine against severe COVID-19 outcomes (hospitalization, critical care admission and death due to COVID-19) and its long-term effectiveness have not been well characterized among the general population. We conducted a retrospective cohort study using electronic health records of 3,147,869 adults, of which 1,099,886 vaccinated individuals were matched, in a 1:1 ratio to 1,099,886 unvaccinated persons. A Cox-proportional hazard model with time varying coefficients was used to assess the vaccine effectiveness adjusting for age, sex, comorbidity, ethnicity, and the calendar month of entry into the study.

Latent Tuberculosis Infection: Treatment Initiation and Completion Rates in Persons Seeking Immigration and Health Care Workers.

Background: We assessed the factors associated with initiation and completion rates of latent tuberculosis (TB) infection treatment in persons evaluated at an infectious diseases outpatient clinic in central Massachusetts. The Centers for Disease Control and Prevention (CDC) estimates that there may be up to 14 million persons in the United States with a latent TB infection. The risk of developing active TB in these persons can range from 5% to 15%.

Modeling of the transport and deposition of polydispersed particles: Effects of hydrodynamics and spatiotemporal evolution of the deposition rate.

A time-distance-dependent deposition model is built to investigate the effects of hydrodynamic forces on the transport and deposition of polydispersed particles and the evolution of deposition rates with time and distance. Straining and the heterogeneity of the particle population are considered to play important roles in the decreasing distribution of deposition rates. Numerical simulations were applied in a series of sand column experiments at different fluid velocities for three different porous media.

Modeling of retention and re-entrainment of mono- and poly-disperse particles: Effects of hydrodynamics, particle size and interplay of different-sized particles retention.

In this paper, numerical simulations of experimental data were performed with kinetic rate coefficients to characterize the retention and re-entrainment dynamics under different hydrodynamic conditions for monodisperse and polydisperse latex particles (3, 10, 16μm and the mixture). The results show that drastic increase in fluid velocity provokes hardly any remarkable decrease in retention in the presence of large energy barriers (>2000kT). Systematical increases in deposition and re-entrainment dynamic rates were observed with fluid velocity and/or particle size.

Porous media grain size distribution and hydrodynamic forces effects on transport and deposition of suspended particles.

The effects of porous media grain size distribution on the transport and deposition of polydisperse suspended particles under different flow velocities were investigated. Selected Kaolinite particles (2-30μm) and Fluorescein (dissolved tracer) were injected in the porous media by step input injection technique. Three sands filled columns were used: Fine sand, Coarse sand, and a third sand (Mixture) obtained by mixing the two last sands in equal weight proportion.

Viral aetiology of bronchiolitis in hospitalised children in Qatar.

Background: Bronchiolitis is considered one of the earliest and most common causes of hospitalisation in young children. Development of molecular technologies allowed a better understanding of bronchiolitis aetiology. Results from cohort studies evaluating the association between single, multiple viral infections and clinical outcomes are conflicting.

Recrudescence of in a Primigravida After Nearly 3 Years of Latency.

We present a case of a primigravid woman who presented with nearly 3 years after she last visited a malaria-endemic region. We review the literature to identify case reports of recrudescent malaria during pregnancy, including those with prolonged latency. Reports of recrudescence of during pregnancy are limited.
