Red flags for depression and PTSD following acute myocardial infarction: the role of early psychological symptoms.

Patients who have experienced an acute myocardial infarction (AMI) are at increased risk of developing depression or post-traumatic stress disorder (PTSD) in the long term. However, whether these psychiatric comorbidities are preceded by early psychological symptoms appearing within the first days after AMI remains unclear. This study provides the identification of early psychological symptoms after AMI and evaluates their predictive value for the subsequent development of AMI-related depression and PTSD.

Physiology of Iron Metabolism.

Background: The essential trace element iron, which can occur in various oxidation states, is required for many biochemical reactions and processes in the human body.

Methods: This review summarizes the current knowledge about the physiology of iron metabolism.

Results: The physiological functions comprise oxygen transport in the blood, electron transport processes, DNA synthesis and gene regulation, the regulation of cell growth and differentiation, and the energy production in mitochondria.

Combined heterozygosity for hemoglobin Paksé, α-thalassemia and for hemoglobin E, β- thalassemia ̵ first appearance in Europe.

Hemoglobinopathies are among the most common inherited diseases and they are believed to be one of the major etiologic factors contributing to anemia. Thalassemia is characterized by an altered hemoglobin (Hb) chain synthesis and may appear as alpha-(α-)thalassemia and/or beta-(β-)thalassemia. The clinical manifestations of thalassemia may range from asymptomatic to severe, with the potential to ultimately result in death.

Homoarginine concentrations correlate with early depressive symptoms and the reduction in physical functioning within the first days after myocardial infarction.

Early depressive symptoms within the first days after acute myocardial infarction (AMI) are mainly manifested with performance parameters (lack of energy, concentration difficulties, reduction in physical functioning). Homoarginine (hArg), a non-proteinogenic amino acid, might increase the availability of nitric oxide (NO). NO controls vasodilatation, blood flow, mitochondrial respiration and improves performance.

Performance evaluation of a smartphone-based home test for fecal calprotection.

Objectives: Fecal calprotectin (FC) serves as a non-invasive marker for the assessment of gut inflammation in patients with inflammatory bowel disease (IBD). Laboratory measurements are usually performed with immunologic methods like enzyme-linked immunosorbent assay. Recently, quantitative home tests based on the lateral flow technology with smartphones as read-out devices have been developed.

Association of Serum Trimethylamine-N-Oxide Concentration from Childhood to Early Adulthood with Age and Sex.

Background: Primary prevention is the cornerstone of cardiometabolic health. In the randomized, controlled Special Turku Coronary Risk Factor Intervention Project (STRIP), dietary counseling intervention was given to children from infancy to 20 years of age and a follow-up was completed at age 26 years. We investigated the associations of age, sex, gut microbiome, and dietary intervention with the gut metabolite and the cardiac biomarker trimethylamine-N-oxide (TMAO).

The role of functional vitamin D deficiency and low vitamin D reservoirs in relation to cardiovascular health and mortality.

Objectives: The role of vitamin D deficiency in cardiovascular disease (CVD) is controversial. Inherent biological and analytical limitations compromise the specificity of widely used 25-hydroxyvitamin D [25(OH)D] cut-offs. Simultaneous determination of 25(OH)D and 24,25-dihydroxyvitamin D [24,25(OH)D] permits a functional assessment of vitamin D metabolism.

One sip of water with LT-4 supplementation-a key to euthyroidism in Hashimoto's thyroiditis.

Purpose: Recommended pharmacotherapy for hypothyroidism in Hashimoto's thyroiditis (HT) is oral supplementation with levothyroxine (LT-4). However, serum thyrotropin (TSH) levels within normal range are not consistently achieved with LT-4 medication.

Patients And Methods: We report on 35 HT patients with LT-4 therapy in this retrospective evaluation.

Classification of Vitamin D Status Based on Vitamin D Metabolism: A Randomized Controlled Trial in Hypertensive Patients.

Circulating 25-hydroxyvitamin D (25(OH)D) is the generally accepted indicator of vitamin D status. Since hydroxylation of 25(OH)D to 24-25-dihydroxyvitamin D (24,25(OH)2D) is the first step of its catabolism, it has been suggested that a low 24,25(OH)D level and a low vitamin D metabolite ratio (VMR), i.e.

Vitamin D and vitamin K status in postmenopausal women with normal and low bone mineral density.

Objectives: Vitamin D and K are believed to promote bone health, but existing evidence is controversial. This study aimed to measure several metabolites of both vitamins by liquid chromatography tandem mass spectrometry (LC-MS/MS) in a cohort of postmenopausal women with low and normal bone mineral density (BMD).

Methods: Vitamin metabolites (25-hydroxyvitamin D (25[OH]D), 24,25-dihydroxyvitamin D (24,25(OH)D), phylloquinone (K1), menaquinone-4 (MK-4) and MK-7) were measured in 131 serum samples by LC-MS/MS.

The possible role of quinolinic acid as a predictive marker in patients with SARS-CoV-2.

Background And Aims: Quinolinic acid (QA) is a metabolite of the kynurenine pathway, which is activated by inflammatory stimuli during viral infection. We investigated the role of QA in patients infected with SARS-CoV-2, particularly its prognostic value for survival.

Methods: Overall, 104 unvaccinated inpatients were included, divided into a survival (N = 80) and a deceased group (N = 24).

Functional Assessment of Vitamin D Status by a Novel Metabolic Approach: The Low Vitamin D Profile Concept.

Background: Determining serum 25-hydroxyvitamin D [25(OH)D], 24,25-dihydroxyvitamin D [24,25(OH)2D] and the vitamin D metabolite ratio (VMR) allows the identification of individuals with a low vitamin D metabolite profile. Here, we evaluated if such a functional approach provides superior diagnostic information to serum 25(OH)D alone.

Methods: 25(OH)D, 24,25(OH)2D, and the VMR were determined in participants of the DESIRE (Desirable Vitamin D Concentrations, n = 2010) and the LURIC (Ludwigshafen Risk and Cardiovascular Health, n = 2456) studies.

Functional Abdominal Pain Disorders in Children May Be Associated with Food Intolerance/Malabsorption.

Functional abdominal pain disorders (FAPDs) are among the most common types of chronic pain disorders in children. FAPD symptoms are characterized by chronic abdominal pain and changed bowel movements. The pathophysiology of FAPDs in children is unknown, but these conditions may have an imprecise clinical overlap to food intolerance/malabsorption.

A personalized management approach in disorders of the irritable bowel syndrome spectrum.

Symptoms of the disorders across the irritable bowel syndrome (IBS) spectrum include several different, usually postprandial, abdominal complaints. Up to date, dietary treatments of the IBS have neither been personalized nor diagnosed with sufficient scientific evidence. They have mostly been treated using 'one-size-fits-all' approaches.

The Use of Next-Generation Sequencing in Pharmacogenomics.

Background: Next-generation sequencing (NGS) methods have become more commonly performed in clinical and research laboratories.

Methods: This review summarizes the current laboratory NGS-based diagnostic approaches in pharmacogenomics including targeted multi-gene panel sequencing, whole-exome sequencing (WES), and whole-genome sequencing (WGS).

Results: Clinical laboratories perform multiple non-uniform types of pharmacogenetic panels, which can reduce the overall number of single-gene tests to be more cost-efficient.

[Clinical Application Examples of a Next-Generation Sequencing based Multi-Genepanel Analysis].

This review provides an overview of clinically useful applications of a next-generation sequencing (NGS)-based multi-gene panel testing strategy in the areas of oncology, hereditary tumor syndromes, and hematology. In the case of solid tumors (e.g.

Fecal Calprotectin Elevations Associated with Food Intolerance/Malabsorption Are Significantly Reduced with Targeted Diets.

Inflammatory bowel disease (IBD) involves two clinically defined entities, namely Crohn's disease and ulcerative colitis. Fecal calprotectin (FCAL) is used as a marker to distinguish between organic IBD and functional bowel disease in disorders of the irritable bowel syndrome (IBS) spectrum. Food components may affect digestion and cause functional abdominal disorders of the IBS spectrum.

ABCB1 Gene Variants and Antidepressant Treatment Outcomes: A Systematic Review and Meta-Analysis Including Results from the CAN-BIND-1 Study.

The P-glycoprotein efflux pump, encoded by the ABCB1 gene, has been shown to alter concentrations of various antidepressants in the brain. In this study, we conducted a systematic review and meta-analysis to investigate the association between six ABCB1 single-nucleotide polymorphisms (SNPs; rs1045642, rs2032582, rs1128503, rs2032583, rs2235015, and rs2235040) and antidepressant treatment outcomes in individuals with major depressive disorder (MDD), including new data from the Canadian Biomarker and Integration Network for Depression (CAN-BIND-1) cohort. For the CAN-BIND-1 sample, we applied regression models to investigate the association between ABCB1 SNPs and antidepressant treatment response, remission, tolerability, and antidepressant serum levels.

Myeloperoxidase as a Potential Biomarker of Acute-Myocardial-Infarction-Induced Depression and Suppression of the Innate Immune System.

While myeloperoxidase (MPO) serves as an indicator of both neutrophil and innate-immune-system function, the potential suppression of the innate immune system in patients with acute myocardial infarction (AMI)-induced depression might be evidenced by a decrease in MPO serum levels. The aim of this prospective study was to (1) determine whether serum concentrations of MPO vary immediately and 6 months after AMI and (2) to investigate whether MPO concentrations at the time of the AMI are significant predictors of AMI-induced depression and the depression-associated suppression of the innate immune system. A total of 109 AMI patients were assessed with the Hamilton Depression Scale (HAMD-17) immediately after admission to the hospital and 6 months later.

Alteration of the kynurenine pathway is inversely associated with the humoral immune response in patients with SARS-CoV-2.

Background: The scale and the course of antibody production in patients with SARS-CoV-2 is highly variable. Factors involved in the immune regulation during the infection may play a major role in the antibody response. We investigated the relationship between the inflammatory markers of the kynurenine pathway and the concentration of antibodies against SARS-CoV-2 in infected patients 8 - 11 days after admission.

[The Impact of Next-Generation Sequencing on Medical Genetic Diagnostics and Counseling].

Next-generation sequencing is a modern diagnostic high-throughput method (multi-gene analysis) that can be used to better diagnose both hereditary cancers (tumor disposition syndromes, germline diagnostics) and somatic mutations in tumors. The broad usage of this technology in daily clinical practice demonstrates the real interindividual genetic variability. This method has great importance for the investigation of heterogeneous genetic diseases (e.
