Identification of novel FosX family determinants from diverse environmental samples.

Objectives: This study aimed to identify novel fosfomycin resistance genes across diverse environmental samples, ranging in levels of anthropogenic pollution. We focused on fosfomycin resistance, and given its increasing clinical importance, explored the prevalence of these genes within different environmental contexts.

Methods: Metagenomic DNA was extracted from wastewater and sediment samples collected from sites in India, Sweden, and Antarctica.

Recent Origin of a Range-Restricted Species With Subsequent Introgression in its Widespread Congener in the Phyteuma spicatum Group (Campanulaceae).

Understanding the causes of restricted geographic distributions is of major interest to evolutionary and conservation biologists. Inferring historical factors has often relied on ad hoc interpretations of genetic data, and hypothesis testing within a statistical framework under different demographic scenarios remains underutilised. Using coalescent modelling on RAD-sequencing data, we (i) test hypotheses about the origin of Phyteuma gallicum (Campanulaceae), a range-restricted endemic of central France sympatric with its widespread congener Ph.

"I'm Trying to Reach Out, I'm Trying to Find My People": A Mixed-Methods Investigation of the Link Between Sensory Differences, Loneliness, and Mental Health in Autistic and Nonautistic Adults.

Background: Rates of loneliness are substantially higher among autistic compared with nonautistic individuals. This observation refutes the persistent stereotype that autistic individuals are not motivated to seek meaningful social relationships. More plausibly, social environments systematically exclude people with higher levels of sensory differences, impeding on opportunities for autistic individuals to form meaningful relationships.

Structures of the Staphylococcus aureus ribosome inhibited by fusidic acid and fusidic acid cyclopentane.

The antibiotic fusidic acid (FA) is used to treat Staphylococcus aureus infections. It inhibits protein synthesis by binding to elongation factor G (EF-G) and preventing its release from the ribosome after translocation. While FA, due to permeability issues, is only effective against gram-positive bacteria, the available structures of FA-inhibited complexes are from gram-negative model organisms.

Cardiovascular risk factor assessment in late-onset seizures: A study protocol to assess the value of structured intervention.

Objective: A growing body of evidence suggests patients with late-onset seizures are at an increased risk of stroke, but the potential for reducing cardiovascular morbidity through risk factor screening and management is unknown. We aim to determine whether individuals with new-onset unprovoked seizures after middle age should undergo vascular risk assessment. The long follow-up needed to assess stroke risk and the known benefit of vascular risk factor modification make a standard RCT logistically and ethically challenging.

Barriers and pathways to environmental surveillance of antibiotic resistance in middle- and low-income settings: a qualitative exploratory key expert study.

Background: Local and global surveillance of antibiotic resistance (ABR) has proven a challenge to implement effectively in low- and middleincome (LMI) settings. Environmental surveillance solutions are increasingly highlighted as a strategy to help overcome such problems, and thus to promote global health as well as the local management of ABR in LMI countries. While technical and scientific aspects of such solutions are being probed continuously, no study has investigated their practical feasibility.

Understanding Stimulation of Conjugal Gene Transfer by Nonantibiotic Compounds: How Far Are We?

A myriad of nonantibiotic compounds is released into the environment, some of which may contribute to the dissemination of antimicrobial resistance by stimulating conjugation. Here, we analyzed a collection of studies to (i) identify patterns of transfer stimulation across groups and concentrations of chemicals, (ii) evaluate the strength of evidence for the proposed mechanisms behind conjugal stimulation, and (iii) examine the plausibility of alternative mechanisms. We show that stimulatory nonantibiotic compounds act at concentrations from 1/1000 to 1/10 of the minimal inhibitory concentration for the donor strain but that stimulation is always modest (less than 8-fold).

Second antiseizure medication monotherapy in patients with adult-onset epilepsy: A register-based analysis.

Objective: Revision of therapy is fundamental in epilepsy care, since only half of patients achieve seizure freedom and tolerate the first antiseizure medication (ASM). We studied the selection and retention of second antiseizure medication monotherapy in adults who discontinued treatment with one of the three most frequently prescribed first ASMs, and the impact of age or brain comorbidities.

Methods: Using Swedish national registers, we conducted a population-based, retrospective cohort study from 2007 to 2019 on patients age ≥ 30 at the epilepsy diagnosis that had switched to a second monotherapy after the three most common initial monotherapies (n = 7369).

Evaluation of culture conditions for sewage-based surveillance of antibiotic resistance in Klebsiella pneumoniae.

Background: Recent studies have shown promise in predicting clinical antibiotic resistance rates from sewage data. Few have focused on Klebsiella pneumoniae, despite its virulence and importance as carrier of antibiotic resistance. Several media have been suggested for the isolation of K.

Adherence to anti-seizure medications in the Swedish Prospective Regional Epilepsy Database and Biobank for Individualized Clinical Treatment (PREDICT).

The aim of this study was to describe the extent of, and risk factors for, non-adherence to anti-seizure medications (ASMs) in adult people with epilepsy (PWE) in Sweden. A cross-sectional multi-centre study was performed of PWEs in western Sweden, with data from medical records, and a questionnaire filled in by the participants including self-reports on how often ASM doses had been forgotten during the past year. Participants were categorized into if they forgot at 0-1 occasion, and if they forgot at 2-10 or >10 occasions.

Prevalence and nature of patient-reported antiseizure medication side effects in a Swedish regional multi-center study.

Purpose: Side effects is one of the major clinical problems in epilepsy care. We assessed the prevalence of ASM side effects in participants in a large regional multicenter observational study in western Sweden and aimed to identify risk factors and inventory the nature of side effects with different ASM regimes.

Methods: Cross-sectional analysis of survey answers and clinical characteristics of 406 adult participants recruited to a regional observational study between December 2020 and March 2023.

The resistome and microbiome of wastewater treatment plant workers - The AWARE study.

Urban wastewater treatment plants harbor a large collection of antibiotic resistant enteric bacteria. It is therefore reasonable to hypothesize that workers at such plants would possess a more diverse set of resistant enteric bacteria, compared to the general population. To address this hypothesis, we have compared the fecal microbiome and resistome of 87 workers at wastewater treatment plants (WWTPs) from Romania and the Netherlands to those of 87 control individuals, using shotgun metagenomics.

Elevated representational similarity of voluntary action and inhibition in Tourette syndrome.

Many people with Tourette syndrome are able to volitionally suppress tics, under certain circumstances. To understand better the neural mechanisms that underlie this ability, we used functional magnetic resonance neuroimaging to track regional brain activity during performance of an intentional inhibition task. On some trials, Tourette syndrome and comparison participants internally chose to make or withhold a motor action (a button press), while on other trials, they followed 'Go' and 'NoGo' instructions to make or withhold the same action.

Pharmaceutical Pollution from Human Use and the Polluter Pays Principle.

Human consumption of pharmaceuticals often leads to environmental release of residues via urine and faeces, creating environmental and public health risks. Policy responses must consider the normative question how responsibilities for managing such risks, and costs and burdens associated with that management, should be distributed between actors. Recently, the Polluter Pays Principle (PPP) has been advanced as rationale for such distribution.

Extensive screening reveals previously undiscovered aminoglycoside resistance genes in human pathogens.

Antibiotic resistance is a growing threat to human health, caused in part by pathogens accumulating antibiotic resistance genes (ARGs) through horizontal gene transfer. New ARGs are typically not recognized until they have become widely disseminated, which limits our ability to reduce their spread. In this study, we use large-scale computational screening of bacterial genomes to identify previously undiscovered mobile ARGs in pathogens.

Antiseizure medication selection and retention for adult onset focal epilepsy in a Swedish health service region: A population-based cohort study.

Objective: Historically, approximately half of those with newly diagnosed epilepsy have responded to and tolerated the first antiseizure medication (ASM), but there are few contemporary real-world data. Third-generation ASMs have improved tolerability and are increasingly used according to prescription data. We aimed to describe current ASM selection and retention in adult onset focal epilepsy in western Sweden.

Wastewater treatment plants, an "escape gate" for ESCAPE pathogens.

Antibiotics are an essential tool of modern medicine, contributing to significantly decreasing mortality and morbidity rates from infectious diseases. However, persistent misuse of these drugs has accelerated the evolution of antibiotic resistance, negatively impacting clinical practice. The environment contributes to both the evolution and transmission of resistance.

Spatiotemporal and microstructural characterization of heterotopic ossification in healing rat Achilles tendons.

Achilles tendon rupture is a common debilitating medical condition. The healing process is slow and can be affected by heterotopic ossification (HO), which occurs when pathologic bone-like tissue is deposited instead of the soft collagenous tendon tissue. Little is known about the temporal and spatial progression of HO during Achilles tendon healing.

Evidence for wastewaters as environments where mobile antibiotic resistance genes emerge.

The emergence and spread of mobile antibiotic resistance genes (ARGs) in pathogens have become a serious threat to global health. Still little is known about where ARGs gain mobility in the first place. Here, we aimed to collect evidence indicating where such initial mobilization events of clinically relevant ARGs may have occurred.

Sampling Considerations for Wastewater Surveillance of Antibiotic Resistance in Fecal Bacteria.

Wastewaters can be analyzed to generate population-level data for public health surveillance, such as antibiotic resistance monitoring. To provide representative data for the contributing population, bacterial isolates collected from wastewater should originate from different individuals and not be distorted by a selection pressure in the wastewater. Here we use diversity as a proxy for representativeness when comparing grab and composite sampling at a major municipal wastewater treatment plant influent and an untreated hospital effluent in Gothenburg, Sweden.

Opportunities to tackle antibiotic resistance development in the aquatic environment through the Water Framework Directive.

Antibiotics are critical components of modern health care. Protecting their efficacy through managing the rise in antibiotic resistance is therefore a global concern. It is not known to what extent environmental pollution from antibiotics contributes to the development of resistance, but encountered concentrations are frequently above concentrations predicted to select for resistance.

Sewage surveillance of antibiotic resistance holds both opportunities and challenges.

A proposed European Union-directive requests that member states monitor antibiotic resistance at all sewage treatment plants serving >100,000 people. Sewage surveillance could provide information on the resistance situation in the underlying population and on environmental transmission risks. There are opportunities to make such surveillance data more informative and actionable, but there are also challenges.
