The natural course of cystic pancreatic neuroendocrine tumours in MEN1.

Pancreatic neuroendocrine tumours (PanNETs) significantly impact life expectancy in multiple endocrine neoplasia type 1 (MEN1). Both solid and cystic pancreatic lesions are observed in MEN1, yet limited research has been focused on cystic lesions in MEN1. While solid PanNETs are generally considered to have an indolent course, the natural course of cystic lesions remains unclear.

Distinct metabolic perturbations link liver steatosis and incident CVD in lean but not obese PWH.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a key risk factor for cardiovascular disease (CVD), potentially driven by shared metabolic mechanisms. Metabolic perturbations associated with MASLD and CVD remain underexplored in people with HIV (PWH).

Methods: We used data from the longitudinal multicenter 2000HIV study comprising 1895 virally suppressed PWH, out of which 970 had available liver and carotid artery measurements.

Gut microbial dysbiosis, IgA, and Enterococcus in common variable immunodeficiency with immune dysregulation.

Background: Common variable immunodeficiency (CVID) is characterized by hypogammaglobulinemia and recurrent infections. Significant morbidity and mortality are caused by immune dysregulation complications (CVIDid), which affect around one-third of CVID patients and have a poorly understood etiology. Here, we investigate the hypothesis that gut microbial dysbiosis contributes to the inflammation underlying CVIDid.

Plasma Proteomic Signature as a Predictor of Age Advancement in People Living With HIV.

Due to the increased burden of non-AIDS-related comorbidities in people living with HIV (PLHIV), identifying biomarkers and mechanisms underlying premature aging and the risk of developing age-related comorbidities is a priority. Evidence suggests that the plasma proteome is an accurate source for measuring biological age and predicting age-related clinical outcomes. To investigate whether PLHIV on antiretroviral therapy (ART) exhibit a premature aging phenotype, we profiled the plasma proteome of two independent cohorts of virally suppressed PLHIV (200HIV and 2000HIV) and one cohort of people without HIV (200FG) using O-link technology.

Rare delayed hypersensitivity reactions to contrast media: Severe cutaneous adverse reactions.

The risk of developing a severe delayed cutaneous reaction (SCAR) is very low following iodine-based contrast medium (ICM) administration and extremely low following gadolinium-based contrast agent (GBCA) administration. However, SCAR can be very severe and potentially life-threatening. It is crucial for the imaging physician to recognize danger signals: bullous skin eruption, skin erosion and detachment, mucosal involvement, systemic symptoms, and laboratory abnormalities.

Role of Short-Range Order on Diffusion Coefficients in the Li-Mg Alloy.

Li-Mg alloys are important because of their beneficial role in fostering uniform plating and stripping of lithium in all-solid-state batteries. The alloy forms a solid solution on the BCC crystal structure when the lithium content is greater than ≈ 0.3.

Innate Immune Cell Functions Contribute to Spontaneous HIV Control.

Purpose Of Review: To review the role of innate immune cells in shaping the viral reservoir and maintenance of long-term viral control of spontaneous Elite and Viremic HIV controllers.

Recent Findings: HIV controllers exhibit a smaller and transcriptionally suppressed viral reservoir. Different studies report that early responses from innate cells play a pivotal role in this reservoir configuration.

Mental health and its consequences in people living with HIV: A network approach.

Objectives: Psychiatric symptoms occur frequently in people living with human immunodeficiency virus (PLWH), which may affect quality of life, sexual risk behavior, and adherence to antiretroviral therapy (ART). Data from large cohorts are limited, and symptoms are often analyzed in isolation. Therefore, we applied a network analysis to assess the interrelatedness of mental health indicators in a large cohort of PLWH.

Plasma proteomic signatures of liver steatosis and fibrosis in people living with HIV: a cross-sectional study.

Background: Insights into the mechanisms driving metabolic dysfunction-associated steatotic liver disease (MASLD) in people living with HIV (PLHIV) remain limited. Plasma proteomics holds promise for biomarker discovery and the elucidation of biological mechanisms.

Methods: We performed cross-sectional analyses on data from 1036 virally suppressed PLHIV using antiretroviral treatment (ART) from the Dutch multi-centre 2000HIV cohort.

Thermodynamic and Kinetic Properties of the Lithium-Silver System.

A carbon-silver anode has recently been shown to suppress dendrite formation in all-solid-state lithium-ion batteries. The role that silver plays in enabling the reversible deposition and stripping of lithium remains unknown. Furthermore, very little is known about the thermodynamic and kinetic properties of Li Ag alloys.

The risk of non-AIDS defining events is lower in ART-naive HIV controllers than in normal progressors on suppressive ART.

Background: We aimed to compare the non-AIDS events (nADE) risk between normal progressors using ART (NP-ART) and people with HIV (PWH) that naturally control HIV infection (HIV controllers), as well as the outcomes after ART in HIV controllers on nADE.

Methods: The primary endpoint was major nADE defined as the composite of cardiovascular disease, non-AIDS malignancy or all-cause mortality, whichever came first..

Fundamental Thermodynamic, Kinetic, and Mechanical Properties of Lithium and Its Alloys.

Lithium alloying reactions are beneficial in promoting uniform plating and stripping of lithium metal in all-solid-state batteries. First-principles calculations are performed to predict thermodynamic, kinetic, and mechanical properties of lithium and several important Li-M alloys (M = Mg, Ag, Zn, Al, Ga, In, Sn, Sb, and Bi). While the Li-Mg binary system forms a solid solution, most other lithium-metal alloys prefer stoichiometric intermetallic compounds with common local motifs that enable fast Li diffusion.

Current Practices and Considerations in Lung Biopsy for Suspected Granulomatous-Lymphocytic Interstitial Lung Disease: A Clinician Survey.

Introduction: This study explores clinicians' diagnostic practices and perceptions in the context of granulomatous-lymphocytic interstitial lung disease (GLILD), a pulmonary manifestation of common variable immunodeficiency disorder. The aim was to gain valuable insights into key aspects, such as the utilization of radiological features for diagnostic purposes, indications for lung biopsy, preferred biopsy techniques, and the relative importance of different histopathological findings in confirming GLILD.

Method: A survey targeting expert clinicians was conducted, focusing on their experiences, practices, and attitudes towards lung biopsy in suspected GLILD cases.

Cation Vacancies Enable Anion Redox in Li Cathodes.

Conventional Li-ion battery intercalation cathodes leverage charge compensation that is formally associated with redox on the transition metal. Employing the anions in the charge compensation mechanism, so-called anion redox, can yield higher capacities beyond the traditional limitations of intercalation chemistry. Here, we aim to understand the structural considerations that enable anion oxidation and focus on processes that result in structural changes, such as the formation of persulfide bonds.

Liver Steatosis is Prevalent in Lean People With HIV and Associated With Exposure to Antiretroviral Treatment-A Cross-sectional Study.

Background: Steatotic liver disease is suggested to have a higher prevalence and severity in people with HIV (PHIV), including in those with a normal body mass index (BMI). In this study, we used data from the 2000HIV cohort to (1) assess the prevalence of liver steatosis and fibrosis in lean versus overweight/obese PHIV and (2) assess associations in these subgroups between steatosis and fibrosis with traditional risk factors and HIV-specific characteristics.

Methods: The 2000HIV study cohort comprises 1895 virally suppressed PHIV that were included between 2019 and 2021 in 4 HIV treatment centers in the Netherlands.

Redox Mechanisms upon the Lithiation of Wadsley-Roth Phases.

The Wadsley-Roth family of transition metal oxide phases are a promising class of anode materials for Li-ion batteries due to their open crystal structures and their ability to intercalate Li at high rates. Unfortunately, most early transition metal oxides that adopt a Wadsley-Roth crystal structure intercalate Li at voltages that are too high for most battery applications. First-principles electronic structure calculations are performed to elucidate redox mechanisms in Wadsley-Roth phases with the aim of determining how they depend on crystal structure.
