December 2024

Department of Health Management and Policy, Faculty of Health Sciences, American University of Beirut, Beirut, Lebanon.

The interrelationality of health and peace is complex, multifactorial, and imbued with political and economic challenges. Peace and health outcomes reflect shared fundamental values related to the achievement of a balanced holistic condition on the individual and collective level. This causal relationship between social inequity and health requires special attention be paid to the impact of political instability and structural violence on undermining health systems in conflict zones.

The great variety of antimicrobial resistance (AMR) profiles among tuberculosis (TB) patients necessitates a comprehensive detection method. This study developed culture-independent, long amplicon-based targeted next-generation sequencing (tNGS) methods for predicting AMR across 16 drugs within the complex (MTBC). Multiplex PCR amplification was employed to enrich 20 gene regions, with sequencing performed on either the Oxford Nanopore Technologies (ONT) or Illumina platforms.

Objective: Variants in PRKN and PINK1 are the leading cause of early-onset autosomal recessive Parkinson's disease, yet many cases remain genetically unresolved. We previously identified a 7 megabases complex structural variant in a pair of monozygotic twins using Oxford Nanopore Technologies (ONT) long-read sequencing. This study aims to determine if ONT long-read sequencing can detect a second variant in other unresolved early-onset Parkinson's disease (EOPD) cases with 1 heterozygous PRKN or PINK1 variant.

Background: Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, accounting for about 85% of all lung cancer cases. While some cases of NSCLC with actionable genomic alterations in the tumour cells may respond to standard therapies, they often show greater improvement with targeted therapies. The current standard of care in Ontario involves testing for actionable genomic alterations using both DNA and RNA panels via tissue testing alone.

Background: In medicine, x-rays are used to generate images of tissues and structures inside the body. X-rays are emitted by a source device and, after passing through the body, strike a detector, which forms an image of the tissues and structures the x-rays passed through. Dual-energy subtraction (DES) x-ray systems use radiation of different energy spectra (energy levels) and the principle of differential absorption characteristics of bone and soft tissue to produce separate bone and soft tissue x-ray images, in addition to a conventional x-ray image.

Musculoskeletal diseases of the foot and ankle are common reasons for primary care consultations. The purpose of this article, which focuses on the seven most common foot and ankle pathologies seen in general practice, is to help general practitioners perform an initial radiological assessment that allows for a correct diagnosis and can then be used by the specialist without the need for repeat imaging. This approach optimizes collaboration between the general practitioner and the specialist, reduces costs, and avoids unnecessary patient radiation.

Service de chirurgie orthopédique et traumatologie de l'appareil moteur, Hôpitaux universitaires de Genève, 1211 Genève 14.

Total knee arthroplasty (TKA) is one of the most performed orthopedic surgeries worldwide. For many years, TKA implants were positioned according to a systematic approach known as mechanical alignment, which prioritized implant survival over the restoration of a more physiological knee. A high dissatisfaction rate of 20% after knee prosthesis has led to a rethinking of coronal alignment and a move towards a more personalized approach.

Article Synopsis
  • Long-read technologies from PacBio and ONT have revolutionized genomics research, but there are ongoing challenges in representing genetic diversity and assembling comprehensive pangenomes.
  • The study investigates the necessary data types and volumes for effective de novo genome assembly in pangenome projects, comparing the performance of ONT's Duplex and PacBio HiFi datasets.
  • Results indicate that achieving high-quality phased genomes requires significant amounts of long reads and various supplemental data, with PacBio HiFi showing better phasing accuracy and ONT Duplex producing more complete contigs.

Molecular characterization of the oral microbiome is a crucial first step in experiments which aim to understand the complex dynamics of the oral microbiome or the interplay with host health and disease. Third-generation Oxford Nanopore Technology (ONT) offers advanced long-read sequencing capabilities, which hold promise for improved molecular characterization by distinguishing closely related microbial species within oral ecosystems in health and disease states. However, the performance of ONT sequencing of oral samples requires validation, and the consistency of this approach across different analytical and sampling conditions is not well understood.

Chemical Sciences and Engineering Division, Argonne National Laboratory, Lemont, Illinois 60439, United States.

Self-assembled organic nanotubes (ONTs) have been actively examined for various applications such as chemical separations and catalysis owing to their well-defined tubular nanostructures with distinct chemical environments at the wall and internal/external surfaces. Adsorption of heavy metal ions onto ONTs plays an essential role in many of these applications but has rarely been assessed quantitatively. Herein, we investigated interactions between Cu and single-/quadruple-wall bolaamphiphile-based ONTs having inner carboxyl groups with different inner diameters, COOH-ONT and COOH-ONT.
