Menetrier's disease (MD) is a protein-losing gastropathy characterized by acute generalized edema due to hypoalbuminemia. MD is rare in childhood, and it is commonly associated with cytomegalovirus infection. We reported two children, who presented with a history of generalized edema after some days of abdominal pain and diarrhea.

Motor axon regeneration after traumatic nerve injuries is a slow process that adversely influences patient outcomes because muscle reinnervation delays result in irreversible muscle atrophy and suboptimal axon regeneration. This advocates for investigating methods to accelerate motor axon growth. Electrical nerve stimulation and exercise both enhance motor axon regeneration in rodents and patients, but these interventions cannot always be easily implemented.

Movement disorders associated with diabetes mellitus (DM) are rare. The diagnosis of diabetic striatopathy (DS) is based on the presence of a triad characterized by hyperglycemia, hemiballismus/chorea, and hypersignal of the basal ganglia on T1-weighted MRI. In most cases, treatment involves glycemic control.

Jansen-de Vries syndrome (JdVS) is an autosomal dominant neurodevelopmental disorder with intellectual disability and gastrointestinal (GI) abnormalities, including recurrent vomiting. This study aimed to understand the frequency and severity of GI symptoms in JdVS patients and to investigate the potential association with cyclic vomiting syndrome (CVS), which has not been previously reported. An international online survey assessed the prevalence and features of CVS and GI disorders in JdVS patients using Rome IV Criteria.

Article Synopsis
  • - Hepatocellular adenomas (HAs) are liver tumors linked to genetic mutations, with this study focusing on a 17-year-old with multiple HAs and a specific pathogenic mutation known to have a dominant negative effect.
  • - The study identified additional somatic variants in some HAs and revealed significant transcriptomic changes, including alterations in various metabolic pathways, angiogenesis, and immune response.
  • - Findings provide a detailed molecular profile of HAs associated with the identified mutation, paving the way for possible non-surgical treatment strategies by pinpointing new therapeutic targets.

The aim of the present study it's a providing an update of the profile of very high-speed running (VHSR) of professional female football players. In this study 23 official matches of the Spanish First Division of Women´s Football were analysed. A total of 15 players participated, who were classified according to their location on the matches played: central-corridor (CCP, n = 7), and lateral-corridor (LCP, n = 8).

In their recent paper, Kingsland and Taiz argue that proponents of plant intelligence and plant neurobiology misuse historical sources to support their claims, suggesting a pattern of bias. They critique the reliance on subjective judgments and the systematic misuse of past literature by notable scientists. This response addresses their criticisms while adhering to Rapoport's rules to foster constructive academic dialogue.

Article Synopsis
  • KCC2 is a cotransporter in neurons that regulates chloride levels, crucial for the function of inhibitory neurotransmitters like GABA and glycine; low KCC2 levels can lead to increased neuronal excitability associated with disorders like epilepsy and neuropathic pain.
  • Axotomy (nerve injury) reduces KCC2 levels in motoneurons, but if the muscle reinnervation occurs, KCC2 levels can recover, suggesting the influence of neurotrophic factors.
  • Administration of VEGF can prevent the KCC2 downregulation after axotomy, while BDNF may decrease KCC2 levels, indicating potential therapeutic avenues for conditions linked to neuronal hyperactivity.

Article Synopsis
  • A study on 219 older patients with type 2 diabetes aimed to investigate the relationship between liver fibrosis, liver steatosis, and cognitive impairment.
  • Results showed that a significant number of patients had mild cognitive impairment (53.88%) or dementia (16.43%), and those with moderate to high risks of liver fibrosis were more likely to have cognitive issues.
  • The study concluded that liver fibrosis, indicated by a FIB-4 score greater than 1.54, is linked to cognitive impairment, suggesting it could be a potential biomarker for detecting cognitive decline in older diabetes patients.

Background: Acute liver failure (ALF) may be the first and most dramatic presentation of Wilson's disease (WD). ALF due to WD (WD-ALF) is difficult to distinguish from other causes of liver disease and is a clear indication for liver transplantation. There is no firm recommendation on specific and supportive medical treatment for this condition.

Introduction: Diabetic macular oedema (DMO) is a complication of diabetic retinopathy that can result in vision loss. The disease can impact different spheres of a patient's life, including physical and psychological health, work, and activities of daily living, entailing an important use of healthcare and non-healthcare resources. This study aimed to estimate the socio-economic burden of DMO in Spain.

Background And Objective: We compared assistance burden between neovascular age-related macular degeneration (nAMD) and retinal angiomatous proliferation (RAP) under intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment on a treat-and-extend (T&E) regimen in a third-level hospital in a developed country.

Patients And Methods: This retrospective study using data from the Fight Retinal Blindness! Registry included patients treated between January 2016 and December 2020.

Cancer immunotherapies strive to overcome tumor-induced immune suppression and activate antitumor immune responses. Although cytotoxic T lymphocytes (CTLs) play a pivotal role in this process, natural killer (NK) cells have also demonstrated remarkable tumor-killing abilities, given their ability to discriminate tumor cells from normal cells and mediate specific antitumoral cytotoxicity. NK cells activation depends on a balance between activation and inhibition signals from several ligands/receptors.

Background And Aims: Alagille syndrome (ALGS) is characterized by chronic cholestasis with associated pruritus and extrahepatic anomalies. Maralixibat, an ileal bile acid transporter inhibitor, is an approved pharmacologic therapy for cholestatic pruritus in ALGS. Since long-term placebo-controlled studies are not feasible or ethical in children with rare diseases, a novel approach was taken comparing 6-year outcomes from maralixibat trials with an aligned and harmonized natural history cohort from the G lobal AL agille A lliance (GALA) study.

Background: In 2018, our center started a program to offer genetic diagnosis to patients with kidney and liver monogenic rare conditions, potentially eligible for organ transplantation. We exploited a clinical exome sequencing approach, followed by analyses of in silico gene panels tailored to clinical suspicions, obtaining detection rates in line with what reported in literature. However, a percentage of patients remains without a definitive genetic diagnosis.

The aim of this work is to delayed the postharvest development of Botrytis cinerea in tomatoes by releasing allyl-isothiocyanate (AITC) from mustard seeds at room temperature, and to discriminate the aromatic profile by using an electronic device (E-nose). Olfactory sensory analysis showed that tomatoes inoculated in the presence of AITC did not develop the microorganisms until the eighth day of storage. The highest inhibitory concentration of AITC was found in Day 3 (175.
