Metabolic syndrome (MS) comprises several symptoms or disorders that significantly increase the risk of developing atherosclerosis and type 2 diabetes. This study aims to determine the direct impact of testosterone therapy on the components of MS; although excluding type 2 diabetes cases. The authors conducted a systematic literature search of PubMed, Scopus, and Cochrane databases without date limits, using keywords such as "testosterone therapy", "metabolic syndrome" and "men".

Lack of sex-specific differences in the associations between the dimensions of great vessels and exercise performance in amateur cyclists.

Background: Endurance training enhances exercise capacity and triggers cardiovascular adaptations in both males and females. We investigated the relationship between the dimensions of great vessels and exercise capacity in amateur cyclists while considering sex differences.

Methods: Using resting transthoracic echocardiography, we measured the dimensions of the main pulmonary artery (PA), aorta, and inferior vena cava (IVC) in 190 participants, who subsequently underwent a cardiopulmonary exercise test (CPET) until exhaustion.

A retrospective analysis of haematological side effects of olaparib in excess-weight and normal BMI patients with ovarian cancer.

Background: Olaparib is the first poly(ADP-ribose) polymerase inhibitor approved in Europe for the treatment of platinum-sensitive patients with newly diagnosed or recurrent platinum-sensitive ovarian cancer with a confirmed BRCA mutation or homologous recombination deficiency (HRD). Epidemiological studies have shown an incompatible association between ovarian cancer and obesity, but there have also been scientific reports indicating that obesity, especially severe obesity, increases the risk of ovarian cancer. Olaparib has a wide range of side effects, especially anaemia and neutropenia, which may lead to dose reduction or therapy discontinuation.

Materials And Methods: The 1244 chorions were tested by targeted quantitative fluorescent PCR (QF-PCR, 827 chorions) and microarray-based comparative genomic hybridization (aCGH, 417 chorions).

Validation of Polish-Language Questionnaires for Assessing the Quality of Life of Patients with Primary Ciliary Dyskinesia (PCD-QOL).

In recent years, questionnaires were published in English to assess the quality of life of patients with PCD (Primary Ciliary Diskinesia) for adults, adolescents aged 13-17 years, and children aged 6-12 years and their caregivers. This study aimed to prepare Polish versions of the questionnaires and validate them in specific age groups with the participation of Polish patients with PCD. The individual questionnaires were translated and discussed with the involvement of the creator of the original questionnaire in English.

Metformin Therapy for Acne Vulgaris: A Meta-Analysis.

Acne vulgaris is a common disease, which occurs in adolescents as well as adults and has a significant influence on the patient's quality of life (QoL) in every aspect. Due to resistance to standard therapies, it has become necessary to prospect for new treatment strategies. It is important to highlight that the diagnosis and treatment of the underlying cause of acne such as metabolic and hormonal disorders may significantly improve the effectiveness of acne treatment.

Visualising and quantifying the usefulness of new predictors stratified by outcome class: The U-smile method.

Binary classification methods encompass various algorithms to categorize data points into two distinct classes. Binary prediction, in contrast, estimates the likelihood of a binary event occurring. We introduce a novel graphical and quantitative approach, the U-smile method, for assessing prediction improvement stratified by binary outcome class.

Overcoming Barriers in Hospital-Based Health Technology Assessment (HB-HTA): International Expert Panel Consensus.

The purpose of this article is to investigate the common facilitators and barriers associated with the implementation of hospital-based health technology assessment (HB-HTA) across diverse hospital settings in seven countries. Through a two-round Delphi study, insights were gathered from a panel of 15 HTA specialists from France, Hungary, Italy, Kazakhstan, Poland, Switzerland, and Ukraine. Experts initially conducted a comprehensive review of the HB-HTA implementation in their respective countries, identifying the barriers and facilitators through descriptive analysis.

A Matter of Margins in Oral Cancer-How Close Is Enough?

In patients with oral cancer, the risk factors for local, regional, and distant recurrence according to margin status have not been well established. We aimed to determine the risk factors for recurrence by margin status and to identify a margin cut-off point for improved survival in patients with close margins. We retrospectively reviewed adult patients treated at our centre from 2009 to 2021 for primary oral cancer.

Oral cancer in young adults: should we approach these patients differently?

Objective: The influence of age on treatment outcomes in oral cancer is unclear. We aimed to determine the prevalence of oral cancer in adults under age 45 and to compare treatment outcomes by age.

Abelson Helper Integration Site 1 haplotypes and peripheral blood expression associates with lithium response and immunomodulation in bipolar patients.

Rationale: In bipolar disorder (BD), immunological factors play a role in the pathogenesis and treatment of the illness. Studies showed the potential link between Abelson Helper Integration Site 1 (AHI1) protein, behavioural changes and innate immunity regulation. An immunomodulatory effect was suggested for lithium, a mood stabilizer used in BD treatment.

Insulin Resistance in Patients with Acne Vulgaris.

Acne vulgaris presents multifactorial pathogenesis, which may include insulin resistance. To investigate whether insulin resistance is a causative factor in acne vulgaris development, this cohort study and a systematic review were conducted. A cohort of 41 acne vulgaris patients and 47 healthy BMI-matched controls were recruited.

MRI and Pulmonary Function Tests' Results as Ventilation Inhomogeneity Markers in Children and Adolescents with Cystic Fibrosis.

Magnetic resonance imaging (MRI) of the chest is becoming more available in the detection and monitoring of early changes in lung function and structure in patients with cystic fibrosis (CF). The aim of this study was to assess the relationship between pulmonary function tests (PFT) and perfusion deficits in CF children measured by MRI.

How Does the Corrected Exhalyzer Software Change the Predictive Value of LCI in Pulmonary Exacerbations in Children with Cystic Fibrosis?

Recently, the most commonly used for multiple breath washout device, the Exhalyzer D, has been shown to overestimate lung clearance index (LCI) results due to a software error. Our study aimed to compare the predictive values of LCI in the CF pulmonary exacerbations (PE) calculated with the updated (3.3.

Purpose: The aim of the study was to ascertain the risk factors of local recurrence in primary basal cell carcinoma of the head and neck Material and methods: A retrospective analysis of 545 patients with head and neck primary basal cell carcinoma treated in years 2008 - 2018 was done. The following data was recorded: age, sex, tumor site, histological subtype, greatest dimension, margin status, experience of operating surgeon and local recurrence Results: Most of the tumors were located nose (165; 30,2%) and auricle (119; 21,8%). The most common pathological subtype was nodular (119; 21,8%).

Cohen's Kappa Coefficient as a Measure to Assess Classification Improvement following the Addition of a New Marker to a Regression Model.

The need to search for new measures describing the classification of a logistic regression model stems from the difficulty in searching for previously unknown factors that predict the occurrence of a disease. A classification quality assessment can be performed by testing the change in the area under the receiver operating characteristic curve (AUC). Another approach is to use the Net Reclassification Improvement (NRI), which is based on a comparison between the predicted risk, determined on the basis of the basic model, and the predicted risk that comes from the model enriched with an additional factor.

Using the Dynamic SWOT Analysis to Assess Options for Implementing the HB-HTA Model.

This paper is aimed at exploring the role of the HB-HTA ecosystem as an important pathway for popularizing the implementation of innovations in healthcare organizations. The scientific debate has largely been focused on the rising importance of HB-HTA and the principles guiding the process. Solutions implemented by individual countries differ, which may be rooted in historical, cultural, and institutional differences.
