Anorexia Nervosa in Polish Children and Adolescents in the Context of the COVID-19 Pandemic-An Observational Single Centre Study.

Introduction: Anorexia nervosa (AN) is a psychiatric disorder with a high mortality rate and significant prevalence in the paediatric population. Preliminary reports during the COVID-19 pandemic suggested an increased incidence of AN among children and adolescents. The objective of this study was to analyse new cases of AN before, during, and after the pandemic, with a particular focus on the physical manifestations of the disease.

Dietary Habits, Awareness, and Knowledge among Polish Healthcare Providers and Healthcare Students.

: Nutrition plays a significant role in preventive medicine, as up to 80% of chronic diseases could be avoided by adhering to healthy dietary principles. The aim of our study was to identify dietary habits, awareness, and nutrition knowledge in a random sample of Polish healthcare students and professionals. Methods: Initially, a total screened sample consisted of 1287 respondents, yet the actual response/participation rate was 634/1287.

Systematic-Narrative Hybrid Literature Review: Crosstalk between Gastrointestinal Renin-Angiotensin and Dopaminergic Systems in the Regulation of Intestinal Permeability by Tight Junctions.

In the first part of this article, the role of intestinal epithelial tight junctions (TJs), together with gastrointestinal dopaminergic and renin-angiotensin systems, are narratively reviewed to provide sufficient background. In the second part, the current experimental data on the interplay between gastrointestinal (GI) dopaminergic and renin-angiotensin systems in the regulation of intestinal epithelial permeability are reviewed in a systematic manner using the PRISMA methodology. Experimental data confirmed the copresence of DOPA decarboxylase (DDC) and angiotensin converting enzyme 2 (ACE2) in human and rodent enterocytes.

The Impact of Prenatal Alcohol Exposure on the Autonomic Nervous System and Cardiovascular System in Rats in a Sex-Specific Manner.

Background: Fetal Alcohol Spectrum Disorder (FASD) is a consequence of prenatal alcohol exposure (PAE) associated with a range of effects, including dysmorphic features, prenatal and/or postnatal growth problems, and neurodevelopmental difficulties. Despite advances in treatment methods, there are still gaps in knowledge that highlight the need for further research. The study investigates the effect of PAE on the autonomic system, including sex differences that may aid in early FASD diagnosis, which is essential for effective interventions.

The autonomic nervous system in anorexia nervosa - an implication for the fat tissue.

Eating disorders are a heterogeneous group of diseases affecting mainly young people in developed countries. Among them, anorexia nervosa (AN) is the one with the highest mortality, up to five times higher compared to healthy individuals. The etiology of this medical condition is complex and still un- certain.

Neuroprotective Activity of Enantiomers of Salsolinol and -Methyl-()-salsolinol: In Vitro and In Silico Studies.

Salsolinol (1-methyl-1,2,3,4-tetrahydroisoquinoline-6,7-diol) is a close structural analogue of dopamine with an asymmetric center at the C1 position, and its presence in vivo, both in humans and rodents, has already been proven. Yet, given the fact that salsolinol colocalizes with dopamine-rich regions and was first detected in the urine of Parkinson's disease patients, its direct role in the process of neurodegeneration has been proposed. Here, we report that and enantiomers of salsolinol, which we purified from commercially available racemic mixture by means of high-performance liquid chromatography, exhibited neuroprotective properties (at the concentration of 50 μM) toward the human dopaminergic SH-SY5Y neuroblastoma cell line.

Expanded insights into the neural component of the activity-based anorexia animal model - morphological changes in the enteric nervous system and altered pain perception.

Anorexia nervosa (AN) is an eating disorder characterized by distinct etiopathogenetic concepts that are gradually being linked together to unravel the dominant pathophysiological pathways underlying the disease. Excessive food restrictions, often accompanied by over-exercise and undertaken to lose weight, lead to the development of numerous complications. The biological concept of neurohormonal dysfunction in AN seems incomplete without demonstrating or excluding the role of the enteric nervous system (ENS).

Retrospective analysis of a case report of a left ovarian ectopic pregnancy after the former tubal.

Up to 2% of pregnancies may be extrauterine. Despite reproductive problems, they might increase the risk of serious complications. We present a case report of a 31-year-old woman with two extrauterine pregnancies - tubal and ovarian, which occurred at the same side with little time difference.

Salsolinol Protects SH-SY5Y Cells Against MPP Damage and Increases Enteric S100-Immunoreactivity in Wistar Rats.

A dopamine derivative, 1-methyl-6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline, known as salsolinol (SAL), has increasingly gained attention since its first detection in the urine of Parkinson's disease patients treated with levodopa, and has been proposed as a possible neurotoxic contributor to the disease. Yet, so far, the neurobiological role of SAL remains unclear. Thus, the main aims of our study were to compare the neurotoxic potential of SAL with MPP (1-methyl-4-phenylpyridinium ion) in vitro, and to examine intestinal and metabolic alterations following intraperitoneal SAL administration in vivo.

The Inhibitory Effect of Human Plasma Albumin and Haptoglobin on Platelet Aggregation and 5-HT Release.

Platelet aggregation contributes to the pathogenesis of cardiovascular diseases. After activation it leads to dense granule secretion and 5-HT release. The question arises; how platelet aggregation is endogenously controlled during blood circulation.

Health-Related Quality of Life in Relation to Fruit and Vegetable Intake among Polish Pharmacists.

A direct association between health-related quality of life (HQoL) and nutrition remains unclear, although lifestyle habits are known to impact on human health. Thus, the aim of this study was to estimate an association between dietary habits, such as vegetable and fruit consumption, in particular, and HQoL. SF-36 (RAND-SF-36) and the Dietary Habits and Nutrition Beliefs Questionnaire (KomPAN) were addressed to Polish pharmacists with a valid professional license.

Hypersensitivity to polyethylene glycol (PEG).

The need for mass population vaccination against Covid-19 poses a public health problem. Allergic symptoms occurring after the 1st dose of the vaccine may result in resignation from the administration of the 2nd dose. However, the majority of patients with mild and/or non-immediate symptoms may be safely vaccinated.

Gastrointestinal Dopamine in Inflammatory Bowel Diseases: A Systematic Review.

Background: an increased prevalence of gastro-duodenal ulceration was described almost sixty years ago as prodromal to idiopathic Parkinson's disease, while duodenal ulcers have been rarely diagnosed in patients with schizophrenia. The cytoprotective role of dopamine in animal models of gastrointestinal ulcerations has also been described. Interestingly, Parkinson's disease (PD) might share common pathophysiological links with inflammatory bowel disease (IBD) as epidemiological and genetic links already suggest.

Cardiotoxicity of Fluoropyrimidines: Epidemiology, Mechanisms, Diagnosis, and Management.

Cancer is a growing public health problem; it is responsible annually for millions of deaths worldwide. Fluoropyrimidines are highly effective and commonly prescribed anti-neoplastic drugs used in a wide range of chemotherapy regimens against several types of malignancies. 5-fluorouracil and its prodrugs affect neoplastic cells in multiple ways by impairing their proliferation, principally through the inhibition of thymidylate synthase.

Is the Activity-Based Anorexia Model a Reliable Method of Presenting Peripheral Clinical Features of Anorexia Nervosa?

Anorexia nervosa (AN) causes the highest number of deaths among all psychiatric disorders. Reduction in food intake and hyperactivity/increased anxiety observed in AN are also the core features of the activity-based anorexia animal model (ABA). Our aim was to assess how the acute ABA protocol mimics common AN complications, including gonadal and cardiovascular dysfunctions, depending on gender, age, and initial body weight, to form a comprehensive description of ABA as a reliable research tool.

Neglected workforce: pharmacists and their health-related quality of life.

Background: pharmacists remain on the frontline of public health around the globe and their performance directly impacts patients' safety. So far, to our knowledge, no European study has been dedicated to their heath-related quality of life (HQoL). Therefore, the primarily aim of our study was to evaluate HQoL of Polish pharmacists utilizing the SF-36 health survey with regard to anthropometric and lifestyle-related variables.

Advancing European nutrition - are pharmacists eligible partners in the process?

Background/objectives: Pharmacists may play an important role in disease prevention through the public education about dietary and lifestyle behaviors, however their expertise is constantly ignored. The study primarily aimed to identify nutrition knowledge and dietary habits among Polish pharmacists.

Subjects: A total sample screened consisted of 1412 respondents, yet 667 (573 females and 94 males) pharmacists finally participated in the study.

Intranasal Bifidobacterium longum protects against viral-induced lung inflammation and injury in a murine model of lethal influenza infection.

Background: Prophylactic strategies are urgently needed for prevention of severe inflammatory responses to respiratory viral infections. Bacterial-host interactions may modify the immune response to viral infections.

Methods: We examined the contribution of Intranasal administration of two different Bifidobacterium longum strains or its isolated cell wall in controlling viral induced inflammation using a murine model of influenza infection.

Backstage of Eating Disorder-About the Biological Mechanisms behind the Symptoms of Anorexia Nervosa.

Anorexia nervosa (AN) represents a disorder with the highest mortality rate among all psychiatric diseases, yet our understanding of its pathophysiological components continues to be fragmentary. This article reviews the current concepts regarding AN pathomechanisms that focus on the main biological aspects involving central and peripheral neurohormonal pathways, endocrine function, as well as the microbiome-gut-brain axis. It emerged from the unique complexity of constantly accumulating new discoveries, which hamper the ability to look at the disease in a more comprehensive way.

Hypothalamic and brain stem neurochemical profile in anorectic rats after peripheral administration of kisspeptin-10 using H-nmr spectroscopy in vivo.

Purpose: Although anorexia nervosa is classified as a psychiatric disorder associated with socio-environmental and psychological factors, a deeper insight into the dominant neurobiological basis is needed to develop a more effective approach of treatment. Given the high contribution of genetic predisposition and the underlying pathophysiology of neurohormonal circuits, it seems that pharmacological targeting of these mechanisms may provide us with better therapeutic outcomes.

Methods: H-NMR spectroscopy was used to measure concentrations of the hypothalamus and brain stem metabolites in an activity-based rodent model (ABA) after subcutaneous administration of kisspeptin-10.

Obesity and disease severity magnify disturbed microbiome-immune interactions in asthma patients.

In order to improve targeted therapeutic approaches for asthma patients, insights into the molecular mechanisms that differentially contribute to disease phenotypes, such as obese asthmatics or severe asthmatics, are required. Here we report immunological and microbiome alterations in obese asthmatics (n = 50, mean age = 45), non-obese asthmatics (n = 53, mean age = 40), obese non-asthmatics (n = 51, mean age = 44) and their healthy counterparts (n = 48, mean age = 39). Obesity is associated with elevated proinflammatory signatures, which are enhanced in the presence of asthma.

Salsolinol-neurotoxic or Neuroprotective?

Salsolinol (6,7-dihydroxy-1-methyl-1,2,3,4-tetrahydroisoquinoline), widely available in many edibles, is considered to alter the function of dopaminergic neurons in the central nervous system and thus, multiple hypotheses on its either physiological and/or pathophysiological role have emerged. The aim of our work was to revisit its potentially neurotoxic and/or neuroprotective role through a series of both in vitro and in vivo experiments. Salsolinol in the concentration range 10-250 μM did not show any significant release of lactate dehydrogenase from necrotic SH-SY5Y cells and was able in the concentration of 50 and 100 μM to rescue SH-SY5Y cells from death induced by HO.

The Autonomic Innervation and Uterine Telocyte Interplay in Leiomyoma Formation.

The autonomic innervation of the uterus is involved in multiple pathophysiological processes in both humans and animals. Pathological conditions such as adenomyosis or inflammatory pelvic disease are usually accompanied by significant alterations in uterine innervation. In the current study, we focused on autonomic innervation of uterine fibroids, the identification of recently described interstitial cells, telocytes, and the possible interplay between these structures.
