The aim of the study was to investigate the question: Can MRI radiomics analysis of the periaqueductal gray region elucidate the pathophysiological mechanisms underlying various migraine subtypes, and can a machine learning model using these radiomics features accurately differentiate between migraine patients and healthy individuals, as well as between migraine subtypes, including atypical cases with overlapping symptoms?

Neurocognitive aging and the associated brain diseases impose a major social and economic burden. Therefore, substantial efforts have been put into revealing the lifestyle, the neurobiological and the genetic underpinnings of healthy neurocognitive aging. However, these studies take place almost exclusively in a limited number of highly­developed countries. Thus, it is an important open

Progressive multifocal leukoencephalopathy with a benign prognosis in an immunocompetent patient – A case report

ZEYNEP ÖZDEMIR, SERAP Ruken TEKER, BURCU YÜKSEL, AYSUN SOYSA

John Cunningham virus (JCV) is most commonly acquired in childhood and is often asymptomatic throughout life. However, in the case of primary or secondary immunosuppression, it is known to cause progressive multifocal leukoencephalopathy (PML) in the central nervous system. Hereby, we describe a rare case of PML in a patient without known factors of immunosuppression or use of immunomodulation.

[Guillain-Barré syndrome caused by intravesical instillation of Bacillus Calmette-Guérin]

AKAN Serkan , ATMACA Colak Melek

[ Guillain-Barré syndrome is an acute inflammatory demyelinating polyneuropathy. In the vast majority of patients, 1-4 weeks before the onset of GBS-related symptoms, an event such as upper respiratory tract or gastrointestinal tract infection, surgical intervention or vaccination is present. To the best of our knowledge, this is the first case of GBS that occurred after intravesical Bacillus Calmette-Guérin therapy in the absence of tuberculosis or any other infection in the English literature.]

[Pharmacotherapy of chronic heart failure with reduced ejection fraction: vericiguat, the developing 5th pillar? ]

HEPP Tamás, VARJAS Norbert, HÉVÍZI Zsombor, BODOR Alexandra, BENCZÚR Béla

[The incidence and prevalence of chronic heart failure (HF) is increasing worldwide, its morbidity and mortality remains high, and its adequate management is of paramount importance. Currently the treatment of heart failure with reduced ejection fraction (HFrEF) relies on four pillars: ACE inhibitors/ARNI, β-blockers, MRAs, and as the newest class, SGLT-2 inhibitors, all of which have been proven to reduce mortality and morbidity in HFrEF patients. A relatively new therapeutic option for the pharmacotherapy of HFrEF is vericiguat a soluble guanylate cyclase stimulator, which modifies the NO-sGC-cGMP signaling pathway impaired in heart failure patients. Vericiguat activates the sGC enzyme independently of the presence of nitric oxide, resulting in elevated intracellular cGMP levels, which can improve endothelial, myocardial, and vascular functions alike. Safety and efficacy of vericiguat were confirmed in the VICTORIA trial. Ve­ri­ci­guat significantly reduced the composite endpoint of HF hospitalization and cardiovascular death compared to placebo in chronic HF patients recently hospitalized for HF or requiring parenteral diuretic therapy with an ejection fraction worse than 45%. The relative risk reduction was 10%, and the absolute risk reduction was 4.2% in the vericiguat group. Due to the positive outcomes observed in the VICTORIA trial, vericiguat was included as a new pharmacotherapeutic option in the 2021 ESC Heart Failure guidelines. The current re­com­mendation suggests the use of vericiguat with a level IIb evidence for HFrEF patients who recently required medical care due to heart failure progression des­pite optimal pharmacotherapy. ]

[Recent results of lifestyle  and drug-induced body-weight reduction ]

BAJNOK László

[Among the specific weight loss diets, there is no convincing fundamental difference in their short-term effects. There is no magic bullet since weight regain is common with all methods in the long term (the greater the reduction the greater the regain). Thus for the majority of patients in need none of them has any significant outcome (–10% per 2 years). Only the safety of some dietary methods has been clarified so far. Although the Mediterranean diet is generally accepted (in a broader context, the Smart Plate developed for domestic conditions by the National Association of Hungarian Dietitians too), however intermittent fasting and e.g. the time-restricted eating may also have some advantages. It would be reasonable to attribute more importance to the patient’s preference during the (repeated) dietetic consultations (the question is who could mediate it authentically?) Nutritional therapy requires essentially (or should require) medical treatment of excess weight, which would also support growing-up of obesitology. In me­tabolic medicine, entero-hormones, primarily glucagon-like peptide-1 receptor agonists (GLP-1 RA), opened a new chapter in the history of medicine. Newer, more ef­fective forms of this drug family make at least 10% weight loss attainable to most of those in need, and as long as their use continues its cardiovascular benefits have also been proven.]
