HIV spreads in the body through two infection patterns: virus-to-cell (VTC) infection and cell-to-cell (CTC) transmission. This study introduces an HIV dynamic model incorporating both transmission patterns, where CTC transmission occurs when healthy CD4 + T cells come into contact with latently and actively infected cells. The research first analyzes the local asymptotic stability of the disease-free equilibrium and the global asymptotic stability of the endemic equilibrium in the deterministic model. Subsequently, a corresponding stochastic HIV model is developed by introducing log-normal Ornstein–Uhlenbeck (OU) process to perturb the infection rates. The study establishes the conditions for the extinction of HIV infection in the stochastic system and examines the existence of an ergodic stationary distribution by constructing a series of stochastic Lyapunov functions. Specifically, the paper proposes the explicit expression of the probability density function for the linearized stochastic system near the quasi-equilibrium when all infected cells transform into latently infected cells. Finally, the theoretical conclusions are validated through numerical simulations. [ABSTRACT FROM AUTHOR]

Valley Fever, or coccidioidomycosis, is a medical condition that can affect both dogs and humans. It is caused by inhaling a species of fungus called Coccidioides, which thrives in the soil of semi-arid regions with warm winters. Most dogs with Valley Fever will have the pulmonary form, presenting with symptoms such as cough, fever, decreased appetite, and weight loss. The fungus can spread to other parts of the body, causing additional signs of illness. Dogs can contract Valley Fever by inhaling fungal spores released from disturbed soil. Diagnosis can be challenging and may require a treatment trial with antifungal medications. Treatment typically involves a lengthy course of antifungal drugs, and the prognosis is generally good if the disease is identified and treated promptly. Precautions can be taken to minimize the risk of dogs becoming ill with Valley Fever, such as avoiding outdoor activity during dust storms and in the days following an earthquake, and not allowing dogs to dig in desert soil. A vaccine for coccidioidomycosis is currently under development. [Extracted from the article]

We extend the unstructured homogeneously mixing epidemic model introduced by Lamprinakou et al. (2023) to a finite population stratified by age bands. We model the actual unobserved infections using a latent marked Hawkes process and the reported aggregated infections as random quantities driven by the underlying Hawkes process. We apply a Kernel Density Particle Filter (KDPF) to infer the marked counting process, the instantaneous reproduction number for each age group and forecast the epidemic's trajectory in the near future. Taking into account the individual inhomogeneity in age does not increase significantly the computational cost of the proposed inference algorithm compared to the cost of the proposed algorithm for the homogeneously unstructured epidemic model. We demonstrate that considering the individual heterogeneity in age, we can derive the instantaneous reproduction numbers per age group that provide a real-time measurement of interventions and behavioural changes of the associated groups. We illustrate the performance of the proposed inference algorithm on synthetic data sets and COVID-19-reported cases in various local authorities in the UK, and benchmark our model to the unstructured homogeneously mixing epidemic model. Our paper is a "demonstration" of a methodology that might be applied to factors other than age for stratification. • Modelling the infections using a latent multidimensional Hawkes process. • Modelling reported cases via a distribution driven by underlying Hawkes process. • Reproduction numbers per age group as a real-time measurement of interventions. • Revealing the dynamics of the epidemic, including who infected whom. • Methodology that might be applied to factors other than age for stratification.

A study conducted by the National Institute of Public Health in Cambodia analyzed six years of programmatic data to identify factors associated with incomplete tuberculosis preventive treatment (TPT). The study found that out of 14,262 individuals with latent TB infection (LTBI) who started TPT, 2.1% did not complete the treatment. Factors such as age, type of medication, and the location where TPT was initiated were found to be associated with non-completion of treatment. The study suggests that prioritizing treatment follow-up for individuals aged 15-34 and initiating TPT at health centers could improve completion rates. Additionally, the study recommends considering a specific medication, 3-month weekly Isoniazid and Rifapentine (3HP), as the first choice of treatment. [Extracted from the article]

This article discusses the heterogeneity of the human immune response to malaria infection and vaccination, specifically focusing on the role of latent cytomegalovirus (CMV) infection. The study found that CMV seropositivity was associated with reduced induction of parasite-specific antibodies following malaria infection and vaccination. Additionally, CMV seropositive individuals had a skew towards T-follicular helper (Tfh) cell subsets before and after malaria infection, and reduced activation of Tfh2 cells. These findings are particularly relevant for malaria endemic regions where CMV infection is acquired early in life and may modify immunity to malaria gained during infection or vaccination.

Clinical studies have shown that this method is sensitive and accurate. Additionally, a large UK study found that the infection has economic consequences, such as a decrease in yearly income and employment, as well as behavioral consequences, including an increase in risky behaviors, stress, and depression. It is important to note that this preprint has not been peer-reviewed. [Extracted from the article]

A preprint abstract discusses a study on rat septal neurons and their response to proliferative arrest and Creutzfeldt-Jakob Disease (CJD) infection. The study found that when the neurons were arrested, they underwent differentiation and exhibited innate immune responses. Normal neurons displayed anti-proliferative and neuron differentiation transcripts, as well as activated IFN innate immune genes. In contrast, CJD-infected neurons downregulated replication controls and suppressed neuronal differentiation transcripts. The study suggests that latent CJD infections can remain clinically silent for over 30 years and may involve shared transcripts with brain microglia, white blood cells, and intestinal myeloid cells. However, it is important to note that this preprint has not been peer-reviewed. [Extracted from the article]

According to a preprint abstract, researchers have found evidence that the Herpes Simplex Virus-1 (HSV-1) can co-opt anti-viral responses for its benefit. The virus encodes a protein called UL12.5, which releases mitochondrial nucleic acid into the cytosol, activating immune sensing pathways and reducing replication in non-neuronal cells. The study found that UL12.5 is required for HSV-1 reactivation in neurons and directly promotes viral gene expression during the initial exit from latency. Additionally, the activation of innate immune sensing pathways can trigger HSV reactivation and compensate for a lack of UL12.5. The study also demonstrated that HSV-1 can respond to and activate antiviral nucleic acid sensing pathways to reactivate from a latent infection. However, it is important to note that this preprint has not been peer-reviewed. [Extracted from the article]

A recent study conducted by researchers at the Federal University Mato Grosso do Sul in Brazil has found that an accelerated local reaction at the injection site following Bacille Calmette-Guerin (BCG) vaccination may be associated with underlying active tuberculosis (TB) in high TB-prevalence settings. The clinical significance of this reaction in individuals without TB symptoms, particularly in low TB-prevalence countries, is still unclear. The study also found that prior mycobacterial exposure, through prior BCG vaccination or latent TB infection, and female sex were key determinants for the occurrence of an accelerated BCG reaction. The researchers suggest that the development of an accelerated local reaction to BCG vaccination in individuals without a prior history of BCG vaccination should prompt further investigations for potential underlying TB infection.
