Introduction/aims: Primary hypokalemic periodic paralysis (HypoPP) can present with periodic paralysis and/or permanent muscle weakness. Permanent weakness is accompanied by fat replacement of the muscle. It is unknown whether the permanent muscle weakness is solely due to fat replacement or if other factors affect the ability of the remaining muscle fibers to contract.

Article Synopsis
  • Primary hypokalemic periodic paralysis (HypoPP) is a muscle condition that causes episodes of paralysis and can lead to permanent muscle weakness; understanding its natural progression could help in treatment evaluation.* -
  • A study examined 37 individuals with HypoPP using MRI to measure fat replacement in muscles and strength tests to track changes over 20 months, revealing increased fat in many muscles but no significant muscle strength changes.* -
  • The findings suggest that MRI is an effective tool for detecting subclinical progression of HypoPP, helping to assess disease progression in both symptomatic and asymptomatic patients.*

Background: Postoperative morbidity can reduce quality of life, physical performance, and tolerability of postoperative chemotherapy in patients with colorectal liver metastases (CRLM). Exercise can improve these outcomes in some cancer populations. However, it remains unknown whether exercise can be delivered in the early postoperative period following surgery for CRLM without increasing the risk of harms.

Article Synopsis
  • The Niemann-Pick type C (NPC) system in eukaryotes facilitates the integration of sterols into the vacuolar/lysosomal membrane, relying on the integral protein NCR1 and the soluble NPC2 protein for sterol transfer.
  • Research shows that the N-terminal domain (NTD) of NCR1 can bind various lipids including ergosterol, cholesterol, and several fluorescent analogs of lipid species like phosphatidylinositol and sphingosine.
  • The study further demonstrates the versatility of the NCR1/NPC2 system in yeast, highlighting its role in the transport and homeostasis of multiple lipids in addition to ergosterol.

Background And Purpose: Intensity modulated proton therapy (IMPT) enables generation of conformal dose plans with organ at risk (OAR) sparing potential. However, pelvic IMPT robustness is challenged by inter-fraction motion caused by constant anatomical variations. In this study, the dosimetric impact of inter-fraction motion on target coverage and dose to OAR was quantified in the prospective phase II study ReRad-II on dose-escalated proton reirradiation for locally recurrent rectal cancer (LRRC).

In patients previously hospitalised for COVID-19, a 12-week high-intensity interval training (HIIT) intervention has previously been shown to increase left ventricular mass (LVM) immediately after the intervention. In the present study, we examined the effects of the same HIIT scheme on LVM, pulmonary diffusing capacity, symptom severity and functional capacity at 12-month follow-up. In this investigator-blinded, randomised controlled trial, 12 weeks of a supervised HIIT scheme (4 × 4 min, three times a week) was compared to standard care (control) in patients recently discharged from hospital due to COVID-19.

Background: Long-term oxygen supplementation for at least 15 hours per day prolongs survival among patients with severe hypoxemia. On the basis of a nonrandomized comparison, long-term oxygen therapy has been recommended to be used for 24 hours per day, a more burdensome regimen.

Methods: To test the hypothesis that long-term oxygen therapy used for 24 hours per day does not result in a lower risk of hospitalization or death at 1 year than therapy for 15 hours per day, we conducted a multicenter, registry-based, randomized, controlled trial involving patients who were starting oxygen therapy for chronic, severe hypoxemia at rest.

Metabolism provides the foundation for all cellular functions. During persistent infections, in adapted pathogenic bacteria metabolism functions radically differently compared with more naïve strains. Whether this is simply a necessary accommodation to the persistence phenotype or if metabolism plays a direct role in achieving persistence in the host is still unclear.

Motivation: Identifying tandem repeat (TR) mutations on a genome-wide scale is essential for understanding genetic variability and its implications in rare diseases. While PacBio HiFi sequencing data enhances the accessibility of the genome's TR regions for genotyping, simple calling strategies often generate an excess of likely false positives, which can obscure true positive findings, particularly as the number of surveyed genomic regions increases.

Results: We developed TRGT-denovo, a computational method designed to accurately identify all types of TR mutations-including expansions, contractions, and compositional changes-within family trios.
