Novel Strategy in the Detection of Adverse Cutaneous Drug Reactions: A Case Series Study.

With multimorbidity on the rise, adverse cutaneous drug reactions are becoming a daily challenge in clinical practice. The objective evaluation of the skin lesion is crucial but hardly realized due to missing technology and guidelines. In this study, the novel Dermus SkinScanner-U, an optically guided high-frequency ultrasound imaging device, was evaluated regarding its comparability with the Dermatology Life Quality Index (DLQI) and the pharmacological analysis of the patients' drug therapy. A total of 40 adult patients were evaluated, all with chronic medication use and skin lesions that led to non-compliance toward the pharmacotherapy. With the ongoing aim of further improving the methodology, the first results, with two detailed patient cases, are presented here. It was concluded that in the cases evaluated, there was a significant correlation between the characteristics of the lesions observed on the optical and ultrasound image, the DLQI score, and the pharmacological analysis. The next steps include increasing the scale of the study to ultimately develop a quality-assured methodology for the correct diagnosis of skin-related adverse drug reactions and to prepare a database with the most frequently observed events.

COVID-19 and Antipsychotic Therapy: Unraveling the Thrombosis Risk.

In the context of the COVID-19 pandemic, this study investigates the potential correlation between the increased use of antipsychotic medications and the rising incidence of venous thromboembolism (VTE). As psychiatric disorders surged, the consequential escalation in antipsychotic drug use raised concerns about thrombotic risks. We conducted a comprehensive literature review using PubMed, focusing on articles that intersected COVID-19, antipsychotic medication, and thrombosis. This approach allowed for a nuanced examination of the historical and recent data on antipsychotic drugs and their association with thrombotic events. Our findings reveal a notable link between the use of antipsychotic medications, particularly second-generation antipsychotics, and an increased risk of VTE, including pulmonary embolism and deep vein thrombosis. This association was evident, despite variations in study designs and populations. The study underscores the need for cautious medication management in psychiatric care, especially during pandemic conditions like COVID-19, to mitigate thrombotic risks. It advocates a personalized approach to prescribing antipsychotics, considering individual patient factors and comorbidities, to balance the benefits against potential thrombotic complications.

Pathways of Coagulopathy and Inflammatory Response in SARS-CoV-2 Infection among Type 2 Diabetic Patients.

Chronic inflammation and endothelium dysfunction are present in diabetic patients. COVID-19 has a high mortality rate in association with diabetes, partially due to the development of thromboembolic events in the context of coronavirus infection. The purpose of this review is to present the most important underlying pathomechanisms in the development of COVID-19-related coagulopathy in diabetic patients. The methodology consisted of data collection and synthesis from the recent scientific literature by accessing different databases (Cochrane, PubMed, Embase). The main results are the comprehensive and detailed presentation of the very complex interrelations between different factors and pathways involved in the development of arteriopathy and thrombosis in COVID-19-infected diabetic patients. Several genetic and metabolic factors influence the course of COVID-19 within the background of diabetes mellitus. Extensive knowledge of the underlying pathomechanisms of SARS-CoV-2-related vasculopathy and coagulopathy in diabetic subjects contributes to a better understanding of the manifestations in this highly vulnerable group of patients; thus, they can benefit from a modern, more efficient approach regarding diagnostic and therapeutic management.

Effect of ractopamine on the release of dopamine from the striatum dissected from mice.

In the past two decades, ractopamine has been used as a feed additive to increase protein synthesis in farmed animals (swine, cattle, and turkeys) and to produce high-quality meat. However, the excessive feeding of animals with ractopamine may result in its accumulation in animal and human tissues after consuming the meat. Ractopamine is a trace amine-associated receptor1 and ß-adrenoceptor agonist banned in the EU but approved in the USA, and it may pose a potential risk to human health. In this paper, the authors, for the first time, provide neurochemical evidence that ractopamine leads to the release of dopamine from nerve terminals of the nigrostriatal pathway in the striatum.

Low cholesterol level as a possible suicide risk factor / Az alacsony szérumkoleszterin-szint mint lehetséges öngyilkossági rizikótényezo.

Összefoglaló. Bevezetés: A koleszterinszint a köztudatban elsosorban mint cardiovascularis rizikófaktor van jelen. Nem mellékes azonban, hogy akár a magas, akár az alacsony koleszterinszint direkt összefüggésbe hozható számos pszichiátriai kórképpel. Célkituzés: A jelen tanulmány célja felhívni a figyelmet a holisztikus nézopont kialakítására, hisz a hypercholesterinaemia korai cardiovascularis elhalálozáshoz vezethet, viszont alacsony koleszterinszint esetén megnövekedhet a hangulatzavarra és foleg az öngyilkosságra való hajlam. Módszer: Kutatásunkban 200 olyan pszichiátriai beteg összkoleszterinszintjét vizsgáltuk meg, akik öngyilkossági gondolatokkal küszködtek. Az öngyilkossági veszélyt a Modified Scale for Suicide Ideation (Miller és mtsai) segítségével mértük. Eredmények: Az elért pontszámok alapján 3 kategóriába soroltuk a betegeket: 52 minimális suicid késztetésu, 49 középsúlyos és 99 súlyos rizikójú beteg. A legsúlyosabb kategóriába tartozó betegek nagy többségének (83 páciens, 84%) összkoleszterinje 4,5 mmol/l alatti volt. A másik két kategóriában ezen arány jelentosen kisebbnek bizonyult: a minimális suicid késztetésu kategóriában ez az érték csak 3 betegre (6%) volt vonatkoztatható, és a középsúlyosak esetén is csak 13 betegre (29%). Megbeszélés: Ezen tanulmányunk hátrányát képezheti a relatíve kis betegszám és a longitudinális utánkövetés megvalósításának hiánya. Következtetés: Jelen eredményeink alapján jogosan vetodhet fel a koleszterinszint mérésének rutinszeru bevezetése mint hatásos, szurésre alkalmas öngyilkossági rizikófaktor biomarker. Orv Hetil. 2021; 162(43): 1732-1739. INTRODUCTION: High cholesterol levels are widely recognized as cardiovascular risk factors. However, lower or higher cholesterol levels can be in a solid relationship with several mental disorders, too. OBJECTIVE: Our study aims to raise awareness about the fact that hypocholesterolemia is involved in various mood disorders and even suicidal behavior looks to be much more frequent. METHOD: Our current study implicates 200 psychiatric patients. These subjects had suicidal ideation upon hospital referral. In the first 24 hours, their total cholesterol levels were measured and the severity of self-harm intentions was evaluated with the Modified Scale for Suicide Ideation by Miller et al. Results: By the obtained evaluation score we differentiated 3 groups: 52 patients with low suicide risk, 49 with moderate risk and 99 with high suicide risk. In this last group, 83 patients had their serum total cholesterol level under 4,5 mmol/L (84%). By comparison, in the low-risk category only 3 patients (6%) and in the moderate-risk 13 patients (29%) were with such levels. DISCUSSION: Clear conclusion cannot be drawn due to the reduced number of our patients, due to the absence of long-term consequent monitorization, and due to the heterogeneity of the studied population. CONCLUSION: Considering these data, a possible usefulness of total cholesterol levels in psychiatric patients may be suggested as a screening tool for the severity of suicidal ideation.

Characterization of unstable pEntYN10 from enterotoxigenic Escherichia coli (ETEC) O169:H41.

Enterotoxigenic Escherichia coli (ETEC) serotype O169:H41 has been an extremely destructive epidemic ETEC type worldwide. The strain harbors a large unstable plasmid that is regarded as responsible for its virulence, although its etiology has remained unknown. To examine its genetic background specifically on the unstable retention and responsibility in the unique adherence to epithelial cells and enterotoxin production, the complete sequence of a plasmid, pEntYN10, purified from the serotype strain was determined. The length is 145,082 bp; its GC content is 46.15%. It contains 182 CDSs, which include 3 colonization factors (CFs), an enterotoxin, and large number of insertion sequences. The repertory of plasmid stability genes was extraordinarily scant. Uniquely, results showed that 3 CFs, CS6, CS8 (CFA/III)-like, and K88 (F4)-like were encoded redundantly in the plasmid with unique variations among previously known subtypes. These three CFs preserved their respective gene structures similarly to those of other ETEC strains reported previously with unique sequence variations respectively. It is particularly interesting that the K88-like gene cluster of pEntYN10 had 2 paralogous copies of faeG, which encodes the major component of fimbrial structure. It remains to be verified how the unique variations found in the CFs respectively affect the affinity to infected cells, host range, and virulence of the ETEC strain.
