Ipsilateral Breast Carcinoma Recurrence: True Recurrence or New Primary? A Clinicopathologic and Molecular Study.

Determining whether an ipsilateral breast carcinoma recurrence is a true recurrence or a new primary remains challenging based solely on clinicopathologic features. Algorithms based on these features have estimated that up to 68% of recurrences might be new primaries. However, few studies have analyzed the clonal relationship between primary and secondary carcinomas to establish the true nature of recurrences.

Ventilation distribution during spontaneous breathing trials predicts liberation from mechanical ventilation: the VISION study.

Background: Predicting complete liberation from mechanical ventilation (MV) is still challenging. Electrical impedance tomography (EIT) offers a non-invasive measure of regional ventilation distribution and could bring additional information.

Research Question: Whether the display of regional ventilation distribution during a Spontaneous Breathing Trial (SBT) could help at predicting early and successful liberation from MV.

Dystonia caused by ANO3 variants is due to attenuated Ca influx by ORAI1.

Background: Dystonia is a common neurological hyperkinetic movement disorder that can be caused by mutations in anoctamin 3 (ANO3, TMEM16C), a phospholipid scramblase and ion channel. We previously reported patients that were heterozygous for the ANO3 variants S651N, V561L, A599D and S651N, which cause dystonia by unknown mechanisms.

Methods: We applied electrophysiology, Ca measurements and cell biological methods to analyze the molecular mechanisms that lead to aberrant intracellular Ca signals and defective activation of K channels in patients heterozygous for the ANO3 variants.

The Role of miR-486-5p on CSCs Phenotypes in Colorectal Cancer.

Background: Colorectal cancer (CRC) is the third diagnosed cancer worldwide. Forty-four percent of metastatic colorectal cancer patients were diagnosed at an early stage. Despite curative resection, approximately 40% of patients will develop metastases within a few years.

The methodology included asking relevant clinical questions based on PICO methodology, a literature search focusing on each question, and a systematic and comprehensive evaluation of the evidence, with a summary of this evidence for each question.

Identification of a new spliceogenic variant causing severe primary coenzyme Q deficiency.

Background And Aims: Primary Coenzyme Q (CoQ) deficiency caused by defects is a clinically heterogeneous mitochondrial condition characterized by reduced levels of CoQ in tissues. Next-generation sequencing has lately boosted the genetic diagnosis of an increasing number of patients. Still, functional validation of new variants of uncertain significance is essential for an adequate diagnosis, proper clinical management, treatment, and genetic counseling.

a data augmentation strategy to narrow the robustness gap between expert radiologists and deep learning classifiers.

Purpose: Successful performance of deep learning models for medical image analysis is highly dependent on the quality of the images being analysed. Factors like differences in imaging equipment and calibration, as well as patient-specific factors such as movements or biological variability (e.g.

Immune-inflammatory effects of the multicomponent intervention FIBROWALK in outdoor and online formats for patients with fibromyalgia.

The multicomponent intervention FIBROWALK integrates pain science education (PSE), therapeutic exercise, cognitive behavioral therapy (CBT), and mindfulness training for treating fibromyalgia (FM). This study investigated the effects of the FIBROWALK in online (FIBRO-On) and outdoor (FIBRO-Out) formats compared to treatment-as-usual (TAU) on core clinical variables along with serum immune-inflammatory biomarkers and brain-derived neurotrophic factor (BDNF). Furthermore, the predictive value of these biomarkers on clinical response to FIBROWALK was also evaluated.

Guidelines for the standardization of pre-analytical variables for salivary biomarker studies in Alzheimer's disease research: An updated review and consensus of the Salivary Biomarkers for Dementia Research Working Group.

There is a pressing need for accessible biomarkers with high diagnostic accuracy for Alzheimer's disease (AD) diagnosis to facilitate widespread screening, particularly in underserved groups. Saliva is an emerging specimen for measuring AD biomarkers, with distinct contexts of use that could complement blood and cerebrospinal fluid and detect various analytes. An interdisciplinary, international group of AD and related dementias (ADRD) researchers convened and performed a narrative review of published studies on salivary AD biomarkers.

Circulating extracellular vesicles and neutrophil extracellular traps contribute to endothelial dysfunction in preeclampsia.

Background: Preeclampsia (PE) is a pregnancy complication characterized by hypertension, proteinuria, endothelial dysfunction, and complement dysregulation. Placenta-derived extracellular vesicles (EVs), necessary in maternal-fetal communication, might contribute to PE pathogenesis. Moreover, neutrophil extracellular traps (NETs) play a pathogenic role in other complement-mediated pathologies, and their contribution in PE remains unexplored.

Carvedilol vs. propranolol for the prevention of decompensation and mortality in patients with compensated and decompensated cirrhosis.

Background And Aims: Data on the effectiveness of classical non-selective beta-blockers (cNSBB, i.e., propranolol and nadolol) versus carvedilol in patients with cirrhosis are scarce.

Biodetection Strategies for Selective Identification of Candidiasis.

Fungi are among the predominant pathogens seen in a greater proportion of infections acquired in healthcare settings. A common fungus that causes infections in medical settings is species. Hospitalized patients who suffer from fungal diseases such as candidiasis and candidemia often have elevated rates of mortality and morbidity.

Effect of three-week exercise program on muscle strength and joint mobility in patients with diabetic polyneuropathy: Randomized controlled trial.

Background: Limited joint mobility is the proven risk factor for diabetic foot ulceration when present in the subtalar and first metatarsophalangeal joints. Evidence shows that a foot-related exercise program, combined with a health-promoting program, can improve the signs and symptoms of diabetic polyneuropathy, enhance gait, restore mobility in the foot and ankle joints, redistribute pressure while walking, and increase foot strength and function. As a result, these exercise programs can help mitigate the risk factors for diabetic foot ulceration.

Asymptomatic carriage of intestinal protists is common in children in Lusaka Province, Zambia.

Background: PCR-based screenings on the presence of diarrhoea-causing intestinal protist species are limited in Zambia, resulting in inaccurate current prevalence and epidemiological data. Sensitive PCR-based methods are particularly well suited for detecting subclinical infections in apparently healthy carriers.

Methodology: In this prospective cross-sectional study, we investigated the occurrence of the most common intestinal protists in an apparently healthy paediatric population (5-18 years) in Lusaka Province, Zambia.

The Potential Predictive Role of Oxidative Stress and Antioxidant Parameters Regarding Mortality and the Type of Causative Agent in Sepsis.

Oxidative stress represents an imbalance between oxidants and antioxidants, with a predominance of oxidants leading to cellular and tissue damage. Given the limited number of studies showing the predictive value of oxidative stress factors regarding sepsis type, the objectives of this study emerged as follows: to determine whether pro-oxidant and antioxidant values could predictively differentiate between Gram-positive (GP) and Gram-negative (GN) sepsis. Additionally, the study sought to assess whether bacterial type impacts treatment outcomes in sepsis patients.

Mitochondria-targeted nanotherapeutics: A new frontier in neurodegenerative disease treatment.

Mitochondria are the seat of cellular energy and play key roles in regulating several cellular processes such as oxidative phosphorylation, respiration, calcium homeostasis and apoptotic pathways. Mitochondrial dysfunction results in error in oxidative phosphorylation, redox imbalance, mitochondrial DNA mutations, and disturbances in mitochondrial dynamics, all of which can lead to several metabolic and degenerative diseases. A plethora of studies have provided evidence for the involvement of mitochondrial dysfunction in the pathogenesis of neurodegenerative diseases such as Parkinson's disease, Alzheimer's disease, Huntington's disease, and amyotrophic lateral sclerosis.

Loss of protects against MASLD alone or with alcohol intake by preserving lipid homeostasis.

Background & Aims: Expression of P21, encoded by the gene, has been associated with fibrosis progression in steatotic liver disease (SLD); however, the underlying mechanisms remain unknown. In the present study, we investigated the function of CDKN1A in SLD.

Methods: expression levels were evaluated in different patient cohorts with SLD, fibrosis, and advanced chronic liver disease (ACLD).

Hyperchylomicronemia causes endothelial cell inflammation and increases atherosclerosis.

The effect of increased triglycerides (TGs) as an independent factor in atherosclerosis development has been contentious, in part, because severe hypertriglyceridemia associates with low levels of low-density lipoprotein cholesterol (LDL-C). To test whether hyperchylomicronemia, in the absence of markedly reduced LDL-C levels, contributes to atherosclerosis, we created mice with induced whole-body lipoprotein lipase (LpL) deficiency combined with LDL receptor (LDLR) deficiency. On an atherogenic Western-type diet (WD), male and female mice with induced global LpL deficiency (i ) and LDLR knockdown ( ) developed hypertriglyceridemia and elevated cholesterol levels; all the increased cholesterol was in chylomicrons or large VLDL.
