Dengue virus is particularly sensitive to interference with long-chain fatty acid elongation and desaturation.

Orthoflaviviruses are emerging arthropod-borne pathogens whose replication cycle is tightly linked to host lipid metabolism. Previous lipidomic studies demonstrated that infection with the closely related hepatitis C virus (HCV) changes the fatty acid (FA) profile of several lipid classes. Lipids in HCV-infected cells had more very long-chain and desaturated FAs and viral replication relied on functional FA elongation and desaturation.

First evidence of human infection by the kinetoplastid flagellate Dimastigella trypaniformis in a patient with urinary tract infection.

We present a case of an 88-year-old man with symptoms consistent with a urinary tract infection, whose diagnostic workup uncovered a previously unrecognized motile flagellated protozoan. Molecular identification confirmed the organism as Dimastigella trypaniformis, a free-living kinetoplastid from the Rhynchomonadidae family. Known only from soil samples in Scotland and termite gut contents in Australia and Germany, Dimastigella trypaniformis has not been previously reported to infect vertebrate hosts.

Longitudinal integrated proteomic and metabolomic skin changes in atopic dermatitis patients treated with dupilumab.

Background: Inhibition of IL-4/IL-13 driven inflammation by dupilumab has shown significant clinical benefits in treatment of atopic dermatitis (AD).

Objective: To assess longitudinal protein and metabolite composition in AD skin during dupilumab treatment.

Methods: Skin tape strip (STS) were collected from lesional/non-lesional skin of 20 AD patients during 16-week dupilumab treatment and from 20 healthy volunteers (HV) followed for 16-weeks.

Exploring and increased acetate biosynthesis in Synechocystis PCC 6803 through insertion of a heterologous phosphoketolase and overexpressing phosphotransacetylase.

Acetate is a biological anion with many applications in the chemical and food industries. In addition to being a common microbial fermentative end-product, acetate can be produced by photosynthetic cyanobacteria from CO using solar energy. Using wild-type cells of the unicellular model cyanobacterium Synechocystis PCC 6803 only low levels of acetate are observed outside the cells.

Long Term Results of a Comparative Study of Percutaneous and Surgically Created Proximal Forearm Arteriovenous Fistulae.

Objective: This retrospective, single centre, comparative effectiveness study aimed to compare the long term outcomes of percutaneous arteriovenous fistulae (pAVF) and surgically created arteriovenous fistulae (sAVF) created in the proximal forearm for haemodialysis access.

Methods: Data were reviewed from a prospectively maintained database on patients who underwent pAVF or sAVF creation from September 2017 to September 2023. A total of 217 pAVFs (61 WavelinQ and 156 Ellipsys) and 158 sAVFs were analysed.

Rationale and Design of the Prevail Global Trial Program Evaluating the Prevail Drug-Coated Balloon in Patients with In-stent Restenosis and De Novo Small Vessel Disease.

Background And Rationale: In-stent restenosis (ISR) remains the leading cause of treatment failure following percutaneous coronary intervention (PCI) with contemporary drug-eluting stents. Especially in small caliber coronary arteries, restenosis is common following PCI and represents a treatment challenge. Drug-coated balloons (DCB) are an attractive alternative to stents for treatment of both ISR and small vessel disease.

Improving MRI turbulence quantification by addressing the measurement errors caused by the derivatives of the turbulent velocity field - Sequence development and in-vitro validation.

Purpose: To improve the current method for MRI turbulence quantification which is the intravoxel phase dispersion (IVPD) method. Turbulence is commonly characterized by the Reynolds stress tensor (RST) which describes the velocity covariance matrix. A major source for systematic errors in MRI is the sequence's sensitivity to the variance of the derivatives of velocity, such as the acceleration variance, which can lead to a substantial measurement bias.

Distribution of BCR::ABL1 transcript types and response to therapy in pediatric patients with chronic myeloid leukemia.

Achieving a stable deep molecular response with the option to discontinue tyrosine kinase inhibitors (TKI) treatment is the new therapeutic goal for patients with chronic myeloid leukemia (CML). Several studies have shown that individuals expressing the BCR::ABL1 e14a2 transcript achieve a major molecular response more rapidly than those with the e13a2 transcript. However, technical issues may have confounded these observations, and data for pediatric patients are limited.

Psychophysiological stress response, emotion dysregulation and sleep parameters as predictors of psychopathology in adolescents and young adults.

Background: Increased emotional reactivity to stress, emotional dysregulation and sleep disturbances are interdependent trans-diagnostic processes that are present in internalising disorders such as depression and anxiety disorders. This study investigated which objective and subjective parameters of stress reactivity, sleep and emotional processing would predict symptoms of anxiety and depression in adolescents and young adults.

Methods: Participants were adolescents and young adults between the ages of 14 to 21 (N = 106, 25[24 %] male, M age = 17.

Specific symptomatology profile associated with treatment resistant depression: A multicentric study from the Group for the Study of Resistant Depression with a focus on sex.

Background: Clinical predictors of treatment-resistant depression could improve treatment strategies. Depressive symptom profiles at baseline are potential outcome predictors, but little evidence is available, and sex-specific profiles have been scarcely investigated.

Methods: Baseline symptom scores of 1294 patients with major depressive disorder were assessed by the Montgomery-Åsberg depression rating scale (MADRS) as part of a multicenter study by the "Group for the Studies of Resistant Depression".

Long-term exposure to air pollution and greenness in association with respiratory emergency room visits and hospitalizations: The Life-GAP project.

Background: Air pollution has been linked to respiratory diseases, while the effects of greenness remain inconclusive.

Objective: We investigated the associations between exposure to particulate matter (PM and PM), black carbon (BC), nitrogen dioxide (NO), ozone (O), and greenness (normalized difference vegetation index, NDVI) with respiratory emergency room visits and hospitalizations across seven Northern European centers in the European Community Respiratory Health Survey (ECRHS) study.

Methods: We used modified mixed-effects Poisson regression to analyze associations of exposure in 1990, 2000 and mean exposure 1990-2000 with respiratory outcomes recorded duing ECRHS phases II and III.

Breast cancer outcomes after skin- and nipple-sparing mastectomy in BRCA pathogenic mutation carriers versus non-BRCA carriers.

Unlabelled: Our previous study on BRCA breast cancer carriers disclosed a high local recurrence (LR) rate in patients who underwent skin sparing (SSM) or nipple sparing mastectomy (NSM) without postoperative radiation therapy (RT), compared to breast conservation surgery or mastectomy with RT. The current study compares the LR rates in BRCA versus non BRCA carriers after SSM/NSM in relation the receipt of RT.

Methods: The study was approved by the institutional ethics committee.

Amyotrophic lateral sclerosis caused by FUS mutations: advances with broad implications.

Autosomal dominant mutations in the gene encoding the DNA and RNA binding protein FUS are a cause of amyotrophic lateral sclerosis (ALS), and about 0·3-0·9% of patients with ALS are FUS mutation carriers. FUS-mutation-associated ALS (FUS-ALS) is characterised by early onset and rapid progression, compared with other forms of ALS. However, different pathogenic mutations in FUS can result in markedly different age at symptom onset and rate of disease progression.

Unique considerations in the assessment and management of traumatic brain injury in older adults.

The age-specific incidence of traumatic brain injury in older adults is rising in high-income countries, mainly due to an increase in the incidence of falls. The severity of traumatic brain injury in older adults can be underestimated because of a delay in the development of mass effect and symptoms of intracranial haemorrhage. Management and rehabilitation in older adults must consider comorbidities and frailty, the treatment of pre-existing disorders, the reduced potential for recovery, the likelihood of cognitive decline, and the avoidance of future falls.

Apixaban versus aspirin for stroke prevention in people with subclinical atrial fibrillation and a history of stroke or transient ischaemic attack: subgroup analysis of the ARTESiA randomised controlled trial.

Background: People with subclinical atrial fibrillation are at increased risk of stroke, albeit to a lesser extent than those with clinical atrial fibrillation, leading to an ongoing debate regarding the benefit of anticoagulation in these individuals. In the ARTESiA trial, the direct-acting oral anticoagulant apixaban reduced stroke or systemic embolism compared with aspirin in people with subclinical atrial fibrillation, but the risk of major bleeding was increased with apixaban. In a prespecified subgroup analysis of ARTESiA, we tested the hypothesis that people with subclinical atrial fibrillation and a history of stroke or transient ischaemic attack, who are known to have an increased risk of recurrent stroke, would show a greater benefit from oral anticoagulation for secondary stroke prevention compared with those without a history of stroke or transient ischaemic attack.

Safety and efficacy of satralizumab in patients with generalised myasthenia gravis (LUMINESCE): a randomised, double-blind, multicentre, placebo-controlled phase 3 trial.

Background: Evidence from preclinical studies suggests that IL-6 signalling has the potential to modulate immunopathogenic mechanisms upstream of autoantibody effector mechanisms in patients with generalised myasthenia gravis. We aimed to assess the safety and efficacy of satralizumab, a humanised monoclonal antibody targeting the IL-6 receptor, in patients with generalised myasthenia gravis.

Methods: LUMINESCE was a randomised, double-blind, placebo-controlled, multicentre, phase 3 study at 105 sites, including hospitals and clinics, globally.

Safety and efficacy of nipocalimab in adults with generalised myasthenia gravis (Vivacity-MG3): a phase 3, randomised, double-blind, placebo-controlled study.

Background: Given burdensome side-effects and long latency for efficacy with conventional agents, there is a continued need for generalised myasthenia gravis treatments that are safe and provide consistently sustained, long-term disease control. Nipocalimab, a neonatal Fc receptor blocker, was associated with dose-dependent reductions in total IgG and anti-acetylcholine receptor (AChR) antibodies and clinically meaningful improvements in the Myasthenia Gravis Activities of Daily Living (MG-ADL) scale in patients with generalised myasthenia gravis in a phase 2 study. We aimed to assess the safety and efficacy of nipocalimab in a phase 3 study.

Hidradenitis suppurativa.

Hidradenitis suppurativa is a chronic inflammatory disease characterised by painful, deep-seated nodules, abscesses, and draining tunnels in the skin of axillary, inguinal, genitoanal, or inframammary areas. In recent years, the body of knowledge in hidradenitis suppurativa has advanced greatly. This disorder typically starts in the second or third decade of life.

Long-term human influence on the demography and genetic diversity of the hyperdominant Bertholletia excelsa in the Amazon Basin.

The Amazon rainforest is characterized by a limited number of hyperdominant trees that play an oversized role in its ecosystems, nutrient cycle, and rainfall production. Some of these, such as the Brazil nut, appear to have been intensively exploited and dispersed by Indigenous populations since their earliest arrival in this part of South America around 13,000 years ago. However, the genetic diversity-and geographic structure-of these species remains poorly understood, as does their exact relationship with past human land use.

Integrative deep immune profiling of the elderly reveals systems-level signatures of aging, sex, smoking, and clinical traits.

Background: Aging increases disease susceptibility and reduces vaccine responsiveness, highlighting the need to better understand the aging immune system and its clinical associations. Studying the human immune system, however, remains challenging due to its complexity and significant inter-individual variability.

Methods: We conducted an immune profiling study of 550 elderly participants (≥60 years) and 100 young controls (20-40 years) from the RESIST Senior Individuals (SI) cohort.

AF4/ICP-ToF-MS for the investigation of species-specific adsorption of organometallic contaminants on natural colloidal particles.

Organotin (OT) compounds, while crucial in many industrial applications, pose substantial risks to the environment and human health. The toxicity and environmental behaviour of OTs depend on their chemical form, i.e.
