Recovering object-location memories after sleep deprivation-induced amnesia.

It is well established that sleep deprivation after learning impairs hippocampal memory processes and can cause amnesia. It is unknown, however, whether sleep deprivation leads to the loss of information or merely the suboptimal storage of information that is difficult to retrieve. Here, we show that hippocampal object-location memories formed under sleep deprivation conditions can be successfully retrieved multiple days following training, using optogenetic dentate gyrus (DG) memory engram activation or treatment with the clinically approved phosphodiesterase 4 (PDE4) inhibitor roflumilast.

Observations of nemaline bodies in muscle biopsies of critically ill patients infected with SARS-CoV-2.

Patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) who have been admitted to the intensive care unit (ICU) often face months of physical disability after discharge. To optimize recovery, it is important to understand the role of musculoskeletal alterations in critically ill patients infected with SARS-CoV-2. The main aim of the present study was to describe the presence and morphology of nemaline bodies found in the skeletal muscle tissue from critically ill patients infected with SARS-CoV-2.

Divergent metabolic phenotypes in two genetic syndromes of low insulin secretion.

Aims: We examined the effect of growth hormone (GH) counter-regulation on carbohydrate metabolism in individuals with life-long diminished insulin secretion (DIS).

Methods: Adults homozygous for the E180 splice site mutation of GHR [Laron syndrome (LS)], adults with a gain-of-function mutation in CDKN1c [Guevara-Rosenbloom syndrome (GRS)], and controls were evaluated for body composition, leptin, total and high molecular weight (HMW) adiponectin, insulin-like growth factor (IGF) axis molecules, and a 5-hour oral glucose tolerance test (OGTT), with measurements of glucose, insulin, glucagon, ghrelin, pancreatic polypeptide, gastric inhibitory peptide, glucagon-like peptide-1, peptide YY, and islet amyloid polypeptide (IAPP).

Results: Both syndromic cohorts displayed DIS during OGTT.

The preferred technique for knee synovium biopsy and synovial fluid arthrocentesis.

For knee osteoarthritis and related conditions, analysis of biomarkers hold promise to improve early diagnosis and/or offer patient-specific treatment. To compare biomarker analyses, reliable, high-quality biopsies are needed. The aim of this work is to summarize the literature on the current best practices of biopsy of the synovium and synovial fluid arthrocentesis.

A Microwell-Based Intestinal Organoid-Macrophage Co-Culture System to Study Intestinal Inflammation.

The mammalian intestinal epithelium contains more immune cells than any other tissue, and this is largely because of its constant exposure to pathogens. Macrophages are crucial for maintaining intestinal homeostasis, but they also play a central role in chronic pathologies of the digestive system. We developed a versatile microwell-based intestinal organoid-macrophage co-culture system that enables us to recapitulate features of intestinal inflammation.

Esophageal Protection and Temperature Monitoring Using the Circa S-Cath™ Temperature Probe during Epicardial Radiofrequency Ablation of the Pulmonary Veins and Posterior Left Atrium.

Although epicardial bipolar radiofrequency ablation should diminish the risk of esophageal thermal injury in comparison to an endocardial ablation, cases of lethal atrio-esophageal fistula have been reported. To better understand this risk and to reduce the possibility of a thermal injury, we monitored the esophageal temperature with the Circa S-Cath™ temperature probe during and immediately after the ablation while implementing three procedural safety measures. Twenty patients (15 males; 63 ± 10 years) were prospectively enrolled (November 2019-February 2021).

Patient characteristics and dispatch responses of urinary tract infections in a prehospital setting in Copenhagen, Denmark: a retrospective cohort study.

Background: Urinary tract infection (UTI) is particularly common in young women and the elderly. The Emergency Medical Services (EMS) in Copenhagen, Denmark can be reached by calling either of two dedicated telephone lines: 1-1-2 in case of an emergency and 1813 during general practitioner's (GP) out-of-office hours (OOH). This study investigated characteristics of patients with symptoms of UTI calling the Copenhagen EMS and the response they received.

The role of birth plans for shared decision-making around birth choices of pregnant women in maternity care: A scoping review.

Background: Birth plans can be used to facilitate shared decision-making in childbirth. A birth plan is a document reflecting women's preferences for birth, which they discuss with their maternity care provider.

Aim: This scoping review aims to synthesize current findings on the role of birth plans for shared decision-making around birth choices of pregnant women in maternity care.

Protein Alterations in Cardiac Ischemia/Reperfusion Revealed by Spatial-Omics.

Myocardial infarction is the most common cause of death worldwide. An understanding of the alterations in protein pathways is needed in order to develop strategies that minimize myocardial damage. To identify the protein signature of cardiac ischemia/reperfusion (I/R) injury in rats, we combined, for the first time, protein matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) and label-free proteomics on the same tissue section placed on a conductive slide.

Wechsler Scale Intelligence Testing in Males with Dystrophinopathies: A Review and Meta-Analysis.

Background: Intelligence scores in males with Duchenne Muscular Dystrophy (DMD) and Becker Muscular Dystrophy (BMD) remain a major issue in clinical practice. We performed a literature review and meta-analysis to further delineate the intellectual functioning of dystrophinopathies.

Method: Published, peer-reviewed articles assessing intelligence, using Wechsler Scales, of males with DMD or BMD were searched from 1960 to 2022.

Neuromodulatory effects of theta burst stimulation to the prefrontal cortex.

Theta burst stimulation (TBS) is a new form of repetitive transcranial magnetic stimulation (TMS) capable of non-invasively modulating cortical excitability. In recent years TBS has been increasingly used as a neuroscientific investigative tool and therapeutic intervention for psychiatric disorders, in which the dorsolateral prefrontal cortex (DLPFC) is often the primary target. However, the neuromodulatory effects of TBS on prefrontal regions remain unclear.

In FUS[1-359]-tg mice O,S-dibenzoyl thiamine reduces muscle atrophy, decreases glycogen synthase kinase 3 beta, and normalizes the metabolome.

Mutations in the gene encoding the RNA/DNA-binding protein Fused in Sarcoma (FUS) have been detected in familial amyotrophic lateral sclerosis (ALS) patients. FUS has been found to be a critical component of the oxidative damage repair complex that might explain its role in neurodegeneration. Here, we examined what impact antioxidant treatment with thiamine (vitamine B1), or its more bioavailable derivative O,S-dibenzoylthiamine (DBT), would have on the hallmarks of pathology in the FUS[1-359]-transgenic mouse model of ALS.

Development of a consensus-based delineation guideline for locally recurrent rectal cancer.

Background And Purpose: Neoadjuvant chemoradiotherapy (nCRT) is used in locally recurrent rectal cancer (LRRC) to increase chances of a radical surgical resection. Delineation in LRRC is hampered by complex disease presentation and limited clinical exposure. Within the PelvEx II trial, evaluating the benefit of chemotherapy preceding nCRT for LRRC, a delineation guideline was developed by an expert LRRC team.

Long non-coding RNA PCAT19 safeguards DNA in quiescent endothelial cells by preventing uncontrolled phosphorylation of RPA2.

In healthy vessels, endothelial cells maintain a stable, differentiated, and growth-arrested phenotype for years. Upon injury, a rapid phenotypic switch facilitates proliferation to restore tissue perfusion. Here we report the identification of the endothelial cell-enriched long non-coding RNA (lncRNA) PCAT19, which contributes to the proliferative switch and acts as a safeguard for the endothelial genome.

Physician-Targeted Interventions in Antibiotic Prescribing for Urinary Tract Infections in General Practice: A Systematic Review.

Urinary tract infections (UTIs) are the most common reason for women to consult a general practitioner (GP). While UTIs are self-limiting in half of cases, most women are prescribed antibiotics, often in discordance with established guidelines. Researchers have employed different interventions to improve GPs' prescribing behavior, especially for respiratory infections, but it is uncertain whether these are effective for UTI care.

The diagnostic accuracy of intraoperative differentiation and delineation techniques in brain tumours.

Brain tumour identification and delineation in a timeframe of seconds would significantly guide and support surgical decisions. Here, treatment is often complicated by the infiltration of gliomas in the surrounding brain parenchyma. Accurate delineation of the invasive margins is essential to increase the extent of resection and to avoid postoperative neurological deficits.

Associations between plasma sulfur amino acids and specific fat depots in two independent cohorts: CODAM and The Maastricht Study.

Purpose: Sulfur amino acids (SAAs) have been associated with obesity and obesity-related metabolic diseases. We investigated whether plasma SAAs (methionine, total cysteine (tCys), total homocysteine, cystathionine and total glutathione) are related to specific fat depots.

Methods: We examined cross-sectional subsets from the CODAM cohort (n = 470, 61.

Discovery of four plasmatic biomarkers potentially predicting cardiovascular outcome in peripheral artery disease.

Peripheral artery disease (PAD) patients have an increased cardiovascular risk despite pharmacological treatment strategies. Biomarker research improving risk stratification only focused on known atherothrombotic pathways, but unexplored pathways might play more important roles. To explore the association between a broad cardiovascular biomarker set and cardiovascular risk in PAD.

Patient experiences and preferences during treatment and recovery of Lisfranc fractures: A qualitative interview study.

Aim: To determine from a patient perspective what improves the quality of care and patient satisfaction during the treatment and recovery process of Lisfranc fractures and to reveal possible points for improvement in this process.

Methods: We performed a qualitative study based on semi-structured interviews with patients treated for a Lisfranc fracture-dislocation in the Netherlands with either open reduction and internal fixation or primary arthrodesis, until data saturation was reached, focusing on the quality of care during treatment and recovery, from a patient perspective.

Results: Data saturation was reached after interviewing 10 patients.

Picomolar fluorescent probes for compound affinity determination to carbonic anhydrase IX expressed in live cancer cells.

Numerous human cancers, especially hypoxic solid tumors, express carbonic anhydrase IX (CAIX), a transmembrane protein with its catalytic domain located in the extracellular space. CAIX acidifies the tumor microenvironment, promotes metastases and invasiveness, and is therefore considered a promising anticancer target. We have designed a series of high affinity and high selectivity fluorescein-labeled compounds targeting CAIX to visualize and quantify CAIX expression in cancer cells.

Retrospective evaluation of national MRI reporting quality for lateral lymph nodes in rectal cancer patients and concordance with prospective re-evaluation following additional training.
