MODERN APPROACH TO DYSPEPSIA.

Dyspepsia is a disorder characterized by dyspeptic symptoms which are located in the epigastrium and related to digestion of food in the initial part of the digestive system. In functional dyspepsia, unlike organic dyspepsia, there is no underlying organic disease that would cause dyspeptic symptoms. Immune and mucosal function changes, gastric dysmotility, different composition of the gastrointestinal microbiota, and altered central nervous system processing are considered responsible for the onset of the disorder.

CROATIAN GUIDELINES FOR THE DIAGNOSIS AND TREATMENT OF NONALCOHOLIC FATTY LIVER DISEASE.

Nonalcoholic fatty liver disease (NAFLD) is a term describing excessive accumulation of fat in hepatocytes, and is associated with metabolic syndrome and insulin resistance. NAFLD prevalence is on increase and goes in parallel with the increasing prevalence of metabolic syndrome and its components. That is why Croatian guidelines have been developed, which cover the screening protocol for patients with NAFLD risk factors, and the recommended diagnostic work-up and treatment of NAFLD patients.

Association of chronic inflammation with cardiovascular risk in chronic obstructive pulmonary disease-A cross-sectional study.

Background And Aims: COPD is progressive lung disease with known higher cardiovascular (CV) risk, mainly attributed to smoking of cigarettes as the main etiological factor of disease. The aim of this study was to compare CV risk in patients with COPD to control groups of smokers and non-COPD and to investigate the relation of lung function variables, COPD severity, and smoking with Systemic Coronary Risk Estimation (SCORE) risk calculation, arterial stiffness (AS) values, and biological systemic inflammatory markers.

Methods: A total of 208 subjects were included in this study: 61 subjects diagnosed with COPD, 83 smokers without COPD, and 64 nonsmokers without COPD.

Changes in Specific Biomarkers Indicate Cardiac Adaptive and Anti-inflammatory Response of Repeated Recreational SCUBA Diving.

Objective: Recreational SCUBA (rSCUBA) diving has become a highly popular and widespread sport. Yet, information on molecular events underlying (patho)physiological events that follow exposure to the specific environmental conditions (hyperbaric conditions, coldness, immersion, and elevated breathing pressure), in which rSCUBA diving is performed, remain largely unknown. Our previous study suggested that repeated rSCUBA diving triggers an adaptive response of cardiovascular and immune system.

Phenotype of limited cutaneous systemic sclerosis patients with positive anti-topoisomerase I antibodies: data from the EUSTAR cohort.

Objectives: To characterize patients with positive anti-topoisomerase I (ATA) in lcSSc.

Methods: SSc patients enrolled in the EUSTAR cohort with a disease duration of ≤3 years at database entry were considered. We assessed the risk of major organ involvement in the following groups: ATA-lcSSc vs ACA-lcSSc and vs ANA without specificity (ANA)-lcSSc, and ATA-lcSSc vs ATA-dcSSc.

FORAMEN OVALE AND FORAMEN ROTUNDUM: CHARACTERIZATION OF POSTNATAL DEVELOPMENT.

The sphenoid bone development occurs in both prenatal and postnatal periods. Sphenoid bone openings are used as surgical landmarks and are of great importance for neurosurgeons in everyday practice. The aim of this study was to identify morphological characteristics, postnatal development and remodeling, as well as clinical aspect of the sphenoid bone openings and to investigate their relationship and difference in size.

The 2019 and 2021 International Workshops on Alport Syndrome.

In 1927 Arthur Cecil Alport, a South African physician, described a British family with an inherited form of kidney disease that affected males more severely than females and was sometimes associated with hearing loss. In 1961, the eponymous name Alport syndrome was adopted. In the late twentieth century three genes responsible for the disease were discovered: , , and encoding for the α3, α4, α5 polypeptide chains of type IV collagen, respectively.

Baseline and progressive adipopenia in newly diagnosed patients with diffuse large B-cell lymphoma with unfavorable features are associated with worse clinical outcomes.

We retrospectively analyzed perirenal and subcutaneous fat thickness and their dynamics from baseline to end-of-treatment computerized-tomography scans in a cohort of 118 newly diagnosed diffuse large B-cell lymphoma (DLBCL) patients with unfavorable features treated with R-DA-EPOCH regimen. Higher revised-international-prognostic-index (R-IPI) score was significantly associated with higher baseline perirenal and lower subcutaneous fat thickness. Up to 51% patients experienced perirenal and 40% subcutaneous fat-tissue loss during immunochemotherapy period.

Impact of lymph node ratio on survival and recurrence outcomes in oral squamous cell carcinoma.

Growing evidence supports the lymph node ratio (LNR) as a prognostic factor for survival in patients with oral squamous cell carcinoma (OSCC). However, there is a lack of data regarding its association with recurrence outcomes. Data on 163 patients with OSCC who underwent primary surgical treatment at a tertiary centre between January 2009 and December 2015 were collected retrospectively and analysed.

Comparison of media and academic attention of recently published positive and neutral or negative randomized cardiovascular clinical trials.

Background: Citations are used to assess the importance of authors, articles and journals in the scientific community, but do not examine how they affect general public journal readership. The Altmetric Attention Score (AAS) is a new metric for measuring media attention of the published paper.

Methods: We examined cardiovascular (CV) randomized clinical trials (RCTs), published in the 3 highest Web of Science Impact Factor journals (Journal Citation Reports 2019: category "Medicine, General & Internal") and in the 3 highest Web of Science Impact Factor CV journals (Journal Citation Reports 2019: category "Cardiac & Cardiovascular Systems"), through the calendar year of 2017, 2018 and 2019.

Impact of Consensus Definitions on Identification of Glomerular Lesions by Light and Electron Microscopy.

Introduction: In 2020, a working group of 13 renal pathologists published consensus definitions for 47 individual glomerular lesions found on light microscopy (LM) and 47 glomerular lesions and 9 normal structures found on electron microscopy (EM).

Methods: To test the impact of these definitions on identification of these lesions and structures, 2 surveys were circulated to all members of the Renal Pathology Society (RPS), each having 32 images (19 LM, 13 EM) and accompanying questions with 5 multiple-choice answers, one being the consensus choice of the working group. The first survey (survey 1 [S1]), answered by 297 RPS members, was sent in September 2020, before publication of the consensus definitions.

Comparison between OPCABG and CABG Surgical Revascularization Using Transit Time Flow Measurement (TTFM).

Objective: To compare the intraoperative quality of coronary anastomoses performed with or without cardiopulmonary bypass using transit time flow measurement (TTFM) parameters.

Methods: We collected data from 588 consecutive patients who underwent surgical revascularization. We retrospectively reviewed data from two groups: 411 with cardiopulmonary bypass (CABG group) and 177 off-pump (OPCABG group).

Two Needle Passes Achieve Similar Diagnostic Yield Compared to Three Passes Regarding Diagnosis of Solid Pancreatic Lesions in Endoscopic Ultrasound-Guided Fine Needle Aspiration.

Current guidelines advocate 3-4 passes with a fine-needle aspiration (FNA) to achieve high rates of diagnostic samples for malignancy when performing endoscopic ultrasound (EUS)-guided sampling of solid pancreatic lesions, in the absence of on-site cytologic evaluation. The aim of this study is to compare 2 vs. 3 needle passes in EUS-FNA for solid pancreatic lesions in terms of incremental diagnostic yield and to identify factors associated with the procedure's outcome.

Guidelines for Genetic Testing and Management of Alport Syndrome.

Genetic testing for pathogenic variants is usually undertaken to investigate the cause of persistent hematuria, especially with a family history of hematuria or kidney function impairment. Alport syndrome experts now advocate genetic testing for persistent hematuria, even when a heterozygous pathogenic or is suspected, and cascade testing of their first-degree family members because of their risk of impaired kidney function. The experts recommend too that or heterozygotes do not act as kidney donors.

Asymptomatic deep vein thromboses in prolonged hospitalized COVID-19 patients.

High incidence of venous thromboembolic (VTE) events in coronavirus disease 2019 (COVID-19) patients has been reported despite pharmacologic thromboprophylaxis. We performed prospective bilateral lower extremity ultrasound evaluation of prolonged hospitalized COVID-19 ward patients from our institution without clinical suspicion of deep vein thrombosis (DVT).A total of 102 patient were included in the study.

COVID-19 in vaccinated adult patients with hematological malignancies: preliminary results from EPICOVIDEHA.

In a Plenary Paper, Mittelman and colleagues assess the relative clinical efficacy of mRNA vaccination on COVID-19 disease incidence and outcomes in patients with hematologic malignancies compared with healthy matched controls. This population-based study from Israel links prior observations of poor serologic responses to vaccination to higher risk for breakthrough infection, hospitalization, and death in patients with blood cancer, especially those on active antineoplastic therapy. In an accompanying Letter to , Pagano et al provide supportive data using a multination survey approach to capture outcomes for COVID-19 in vaccinated patients with hematologic neoplasms.

Anti-inflammatory adipokines: chemerin, vaspin, omentin concentrations and SARS-CoV-2 outcomes.

Coronavirus disease 2019 (COVID-19) is associated with systemic inflammation. A wide range of adipokines activities suggests they influence pathogenesis and infection course. The aim was to assess concentrations of chemerin, omentin, and vaspin among COVID-19 patients with an emphasis on adipokines relationship with COVID-19 severity, concomitant metabolic abnormalities and liver dysfunction.

Fetuin-A Deficiency but Not Pentraxin 3, FGF-21, or Irisin, Predisposes to More Serious COVID-19 Course.

Analysis of liver biopsy specimens showed that SARS-CoV-2 might have led to liver damage. This study aimed to evaluate the role of selected hepatokines and myokines in the development and progression of COVID-19. Seventy patients with laboratory-confirmed COVID-19 and 20 healthy volunteers were enrolled in the study.

COVID-19 in the endoscopy unit: How likely is transmission of infection? Results from an international, multicenter study.

Background: Coronavirus disease 2019 (COVID-19) significantly affected endoscopy practice, as gastrointestinal endoscopy is considered a risky procedure for transmission of infection to patients and personnel of endoscopy units (PEU).

Aim: To assess the impact of COVID-19 on endoscopy during the first European lockdown (March-May 2020).

Methods: Patients undergoing endoscopy in nine endoscopy units across six European countries during the period of the first European lockdown for COVID-19 (March-May 2020) were included.

Malignant transformation of pleomorphic xanthoastrocytoma in pregnant patient: Clinical case and ethical dilemma.

Background: Pleomorphic xanthoastrocytoma (PXA) is a rare astrocytic tumor, accounting for <1% of astrocytic tumors. Due to its rarity, etiology, natural history, and biologic behavior is not completely explained. We present a case of malignant transformation of a PXA to glioblastoma in pregnant patient 6 month after tumor biopsy.

A CHILD WITH DENSE DEPOSIT DISEASE AND DECREASED CLASSIC COMPLEMENT PATHWAY ACTIVITY.

We report a rare case of nephritic syndrome underlying dense deposit disease (DDD) with alternative complement pathway dysfunction explained with both C3 nephritic factor (C3NeF) antibodies and DDD associated polymorphism of factor H. An 8-year-old boy presented with macroscopic hematuria, hypertension and periorbital edema followed by persistently low C3 during the 8-week follow-up. Positive C3 staining on immunofluorescence microscopy, supported by dense deposits within the glomerular basement membrane on electron microscopy, confirmed the diagnosis of DDD.
