PURPOSE OF REVIEW: Men face distinctive health-related challenges as a result of biological, behavioral, and sociocultural factors. In addition, the modern healthcare system does not offer men equal opportunities and options to ensure sex-specific access and delivery to health services. Men's health concerns are, indeed, often not addressed or even forgotten. In this review, we wanted to assess the impact of biology and sociocultural effects on sex-specific life-expectancy. RECENT FINDINGS: Globally, men have a shorter life expectancy than women. With a 5.8 years gender gap in the USA and 5.4 in the EU-27 (both in 2022). Cardiovascular disease, cancer, and accidents continue to represent the primary causes of mortality for both genders with all having disproportional preponderance in men. In recent years, there has been a notable decline in age-adjusted mortality rates related to cancer, while there has been an increase in deaths from accidental and intentional self-harm. Moreover, in the United States, men are more likely than women to develop and die from nonsex-specific cancers. As a result, men's poor health affects productivity, absenteeism, and employment. SUMMARY: The status of men in healthcare is complex. It is rooted in history, culture, and institutions. To address disparities, we need a comprehensive approach that includes policy reforms, sociocultural changes, and a fair and equitable public discourse. Grassroots and top-down strategies are needed to ensure a value-based societal healthcare system acknowledging the unique health needs of men.

BACKGROUND: Widespread use of pneumococcal conjugate vaccines (PCVs) has reduced vaccine-type invasive pneumococcal disease (IPD). We describe the serotype distribution of IPD after extensive use of ten-valent PCV (PCV10; Synflorix, GSK) and 13-valent PCV (PCV13; Prevenar 13, Pfizer) globally. METHODS: IPD data were obtained from surveillance sites participating in the WHO-commissioned Pneumococcal Serotype Replacement and Distribution Estimation (PSERENADE) project that exclusively used PCV10 or PCV13 (hereafter PCV10 and PCV13 sites, respectively) in their national immunisation programmes and had primary series uptake of at least 70%. Serotype distribution was estimated for IPD cases occurring 5 years or more after PCV10 or PCV13 introduction (ie, the mature period when the serotype distribution had stabilised) using multinomial Dirichlet regression, stratified by PCV product and age group (<5 years, 5-17 years, 18-49 years, and ≥50 years). FINDINGS: The analysis included cases occurring primarily between 2015 and 2018 from 42 PCV13 sites (63 362 cases) and 12 PCV10 sites (6806 cases) in 41 countries. Sites were mostly high income (36 [67%] of 54) and used three-dose or four-dose booster schedules (44 [81%]). At PCV10 sites, PCV10 serotypes caused 10·0% (95% CI 6·3-12·9) of IPD cases in children younger than 5 years and 15·5% (13·4-19·3) of cases in adults aged 50 years or older, while PCV13 serotypes caused 52·1% (49·2-65·4) and 45·6% (40·0-50·0), respectively. At PCV13 sites, PCV13 serotypes caused 26·4% (21·3-30·0) of IPD cases in children younger than 5 years and 29·5% (27·5-33·0) of cases in adults aged 50 years or older. The leading serotype at PCV10 sites was 19A in children younger than 5 years (30·6% [95% CI 18·2-43·1]) and adults aged 50 years or older (14·8% [11·9-17·8]). Serotype 3 was a top-ranked serotype, causing about 9% of cases in children younger than 5 years and 14% in adults aged 50 years or older at both PCV10 and PCV13 sites. Across all age and PCV10 or PCV13 strata, the proportion of IPD targeted by higher-valency PCVs beyond PCV13 was 4·1-9·7% for PCV15, 13·5-36·0% for PCV20, 29·9-53·8% for PCV21, 15·6-42·0% for PCV24, and 31·5-50·1% for PCV25. All top-ten ranked non-PCV13 serotypes are included in at least one higher-valency PCV. INTERPRETATION: The proportion of IPD due to serotypes included in PCVs in use was low in mature PCV10 and PCV13 settings. Serotype distribution differed between PCV10 and PCV13 sites and age groups. Higher-valency PCVs target most remaining IPD and are expected to extend impact. FUNDING: Bill & Melinda Gates Foundation as part of the WHO Pneumococcal Vaccines Technical Coordination Project.

TFE3 rearrangements characterize histogenetically, topographically, and biologically diverse neoplasms. Besides being a universal defining feature in alveolar soft part sarcoma (ASPS) and clear cell stromal tumor of the lung, TFE3 fusions have been reported in subsets of renal cell carcinoma, perivascular epithelioid cell tumor (PEComa), epithelioid hemangioendothelioma and ossifying fibromyxoid tumors. TFE3 -related neoplasms are rare in the head and neck and may pose diagnostic challenges. We herein describe 22 TFE3 fusion neoplasms affecting 11 males and 11 females aged 4 to 79 years (median, 25) and involving different head and neck sites: sinonasal cavities (n = 8), tongue (n = 4), oral cavity/oropharynx (n = 3), salivary glands (n = 2), orbit (n = 2), and soft tissue or unspecified sites (n = 3). Based on morphology and myomelanocytic immunophenotype, 10 tumors qualified as ASPS, 7 as PEComas (3 melanotic; all sinonasal), and 5 showed intermediate (indeterminate) histology overlapping with ASPS and PEComa. Immunohistochemistry for TFE3 was homogeneously strongly positive in all cases. Targeted RNA sequencing/FISH testing confirmed TFE3 fusions in 14 of 16 successfully tested cases (88%). ASPSCR1 was the most frequent fusion partner in ASPS (4 of 5 cases); one ASPS had a rare VCP::TFE3 fusion. The 6 successfully tested PEComas had known fusion partners as reported in renal cell carcinoma and PEComas ( NONO, PRCC, SFPQ , and PSPC1 ). The indeterminate tumors harbored ASPSCR1::TFE3 (n = 2) and U2AF2::TFE3 (n = 1) fusions, respectively. This large series devoted to TFE3-positive head and neck tumors illustrates the recently proposed morphologic overlap in the spectrum of TFE3 -associated mesenchymal neoplasms. While all PEComas were sinonasal, ASPS was never sinonasal and occurred in diverse head and neck sites with a predilection for the tongue. The indeterminate (PEComa-like) category is molecularly more akin to ASPS but shows different age, sex, and anatomic distribution compared with classic ASPS. We report VCP as a novel fusion partner in ASPS and PSPC1 as a novel TFE3 fusion partner in PEComa (detected in one PEComa). Future studies should shed light on the most appropriate terminological subtyping of these highly overlapping tumors.

The COVID-19 Pandemic contributed to accelerating the process of using information and communication technologies and digital technologies in healthcare management and delivery within healthcare systems. At that time, the Czech healthcare system faced the same problems as other European systems and struggled with a temporary limitation of direct provision of healthcare services. It was solved by switching to telemedicine. The Czech healthcare system used telemedicine to a minimal extent until then. Despite adopting the law on healthcare digitisation, it is still one of the countries with a lower level of digitisation of healthcare processes. The article presents the results of an exploratory expert investigation focused on the implementation and development of telemedicine in the Czech Republic. The conducted research aimed to identify problems related to the implementation of telemedicine in practice, place them in the broader framework of the healthcare system and structure them, propose possible solutions, and identify the future challenges of telemedicine in the Czech Republic. We based our study on the results of a three-phase QUAL-QUAN-QUAL research. Data collection in the first phase took the form of individual semi-structured interviews with patients (25) with practical experience in the field of telemedicine, followed by the second quantitative phase of the questionnaire survey with patients (650). The third qualitative phase included semi-structured interviews with experts (17) with practical experience in telemedicine. The introduction and expansion of telemedicine require several fundamental changes. These include adjustments to the legislative environment and changes to the technological infrastructure, organisation of care and work. Several barriers have been identified at the healthcare system level, healthcare providers, healthcare professionals and patients.

The aim of this study was to analyse the allelic distribution of selected genes in the Czech and Vietnamese populations. We analysed samples from 94 Vietnamese volunteers and 2,859 Czech population-based subjects (2,559 from the Czechs post-MONICA and 300 volunteers from the South region of the Czech Republic). There were significant differences between the two populations for most, but not all, of the SNPs analysed. In particular, the prevalence of risk alleles in the analysed polymorphisms tended to be lower in the Vietnamese community compared to the Czech population, especially within the FTO (rs17817449; associated with obesity risk, P < 0.0001), TCF7L2 (rs7903146; linked to type 2 dia-betes, P < 0.0001) and ADH1B (rs1229984; related to alcohol consumption, P < 0.0001) genes. The genotype within the MCM6/LCT cluster (rs4988235) associated with lactase persistence was not present in the Vietnamese population. Slight genotype differences were detected for one HFE polymorphism (rs1799945 with P = 0.005; but not for rs1800562). Only the genotype frequencies within the MC4R and APOE genes were almost identical in both populations. We conclude that the Vietnamese population may have a lower genetic predisposition to the non-communicable diseases such as obesity or diabetes mellitus.

Úvod: Shigelóza je vysoce nakažlivé průjmové onemocnění s potenciálně velmi závažným průběhem. I s ohledem na třetinový nárůst případů v roce 2023 ve srovnání s rokem předchozím jsme si stanovili za cíl podat přehled aktuálních informací o onemocnění a analyzovat data nahlášených případů shigelózy v České republice (ČR). Metody: Zpracovali jsme narativní rešerši odborné literatury v českém a anglickém jazyce, zejména cílenou na evropské studie od roku 2018. Dále jsme provedli analýzu dat hlášených pod kódem diagnózy A03 v národním systému pro hlášení infekčních nemocí (ISIN) v letech 2018–2023. Soustředili jsme se na hlavní epidemiologické ukazatele, zejména pohlaví, věk, geografickou distribuci, sezonnost a hospitalizace. Použity byly programy Excel (verze 2016), STATA (verze 17) a Datawrapper GmbH. Výsledky: Celkem bylo nahlášeno 681 případů onemocnění shigelózou s průměrnou roční incidencí 1/100 000 obyvatel: do roku 2021 byla incidence mírně vyšší u žen, od roku 2022 evidujeme trend opačný. V pandemických letech byl zaznamenán významný pokles případů. V letech 2022 a 2023 byl počet případů mírně vyšší než v období před pandemií. Nejvíce případů evidujeme v ČR každoročně v měsících srpen až prosinec. Ze všech sérotypů shigel byla nejčastěji detekována S. sonnei (80 %), následovaná S. flexneri (15 %). Incidence na 100 000 obyvatel byla nejvyšší u osob ve věku 5–9 let: 2,6 (chlapci 2,4 a dívky 2,8), dále 1–4 roky: 2,4 (chlapci 2,2, dívky 2,6) a osob ve věku 25–34 let: 1,8 (muži 1,8 a ženy 1,7). Podle krajů byla průměrná roční specifická incidence nejvyšší v krajích Moravskoslezském, Olomouckém a v hlavním městě Praze. Hospitalizováno bylo 27 % případů, nejvíce ve věkových skupinách 25–34 a 5–9 let (shodně 17,9 %). Proporce hospitalizovaných případů v rámci jednotlivých věkových skupin byla nejvyšší ve věkové skupině 75+ let (69 %), dále věkových skupinách 1–4 roky, 5–9 let a 65–74let (32–37 %). V souvislosti s onemocněním bylo vykázáno jedno úmrtí muže ve věku 52 let. V rámci epidemického výskytu bylo nahlášeno 11 % případů. Importováno bylo 39 % nahlášených případů. Závěr: V ČR je shigelóza spíše málo zastoupeným gastrointestinálním onemocněním, přičemž téměř 40 % případů tvoří importované nákazy. V současnosti je hrozbou pro veřejné zdraví především globální šíření multirezistentních kmenů podpořené narůstajícím cestovním ruchem a volnými sexuálními praktikami. Rizikovými skupinami zůstávají děti, imunokompromitované osoby (včetně seniorů) a muži mající sex s muži. Očkování není v Evropě dostupné. Stěžejním je nadále dodržování základních hygienických pravidel, zejména v kolektivech a při práci s potravinami. Důraz by měl být dále kladen na zdravotní edukaci osob, včetně poučení před vycestováním do zahraničí. Důkladná anamnéza, včasné trasování, dohled a racionální volba eventuální antibiotické terapie jsou zásadní. V ČR musí být všechny suspektní kmeny zaslány do NRL ke konfirmaci. Celogenomovou sekvenaci a testy citlivosti na antibiotika je vhodné provádět u všech izolátů.

Introduction: Shigellosis is a highly contagious diarrheal disease, which could potentially be very serious. Considering the onethird increase in cases in 2023 compared to the previous year, we aimed to provide an update on the disease and to analyse data on reported cases of shigellosis in the Czech Republic (CZ). Methods: We conducted a narrative search of the literature in Czech and English, particularly targeting European studies from 2018 onwards. We also analysed data reported under the diagnosis code A03 to the National Infectious Disease Reporting System (ISIN) in 2018–2023. We focused on the main epidemiological indicators, i.e. gender, age, geographical distribution, seasonality, and hospitalizations. Excel (version 2016), STATA (version 17), and Datawrapper GmbH were used. Results: A total of 681 shigellosis cases were reported with an average annual incidence of 1/100,000 population: until 2021, the incidence was slightly higher in women, while from 2022 onwards, the trend was reversed. A significant decrease in cases was recorded in the pandemic years. In 2022 and 2023, the number of cases was slightly higher than in the pre-pandemic period. Most cases were detected in CZ in August and December each year. Of all shigella serotypes, S. sonnei was the most frequently detected (80%), followed by S. flexneri (15%). The incidence per 100.000 population was highest among children aged 5–9 years: 2.6 (boys 2.4 and girls 2.8), followed by 1–4-year-olds: 2.4 (2.2 and 2.6, respectively) and persons aged 25–34 years: 1.8 (males 1.8 and females 1.7). Within individual age group, the average annual specific incidence rates were highest in the Moravian-Silesian and Olomouc regions and the capital city Prague. Hospitalizations accounted for 27% of cases, with the highest numbers in the 25–34 and 5–9 age groups (both 17.9%). The proportion of hospitalized cases was highest in the age groups 75+ (69%), 1–4, 5–9, and 65–74 (32–37%). A 52-year-old man was reported to have die in relation to the disease. Eleven percent of cases were reported in outbreak settings. Thirty-nine percent of reported cases were imported. Conclusions: In CZ, shigellosis is a relatively rare gastrointestinal disease, with nearly 40% of cases being imported. At present, the threat to public health is posed mainly by the global spread of multi-resistant strains linked to increasing tourism and free sexual practices. Children, immunocompromised persons (including the elderly), and men who have sex with men remain risk groups. Vaccination is not available in Europe. Compliance with basic hygiene rules, especially in collectives and when working with food, is still a key concern. Emphasis should also be placed on the health education, including instructions before traveling abroad. A thorough medical history, early tracing, surveillance, and rational choice of antibiotic therapy if appropriate are essential. In CZ, all suspected strains shall be sent to the NRL for confirmation. Whole genome sequencing and antibiotic susceptibility testing should be performed on all isolates.

This study aimed to investigate the effects of performing either eccentric-only (ECC) or eccentric-concentric (ECC-CON) back squats (BS) with a supramaximal load on countermovement jump (CMJ) performance. Changes in front thigh skin surface temperature and mechanical properties (oscillation frequency and stiffness) of the vastus lateralis were also examined. Fourteen male powerlifters participated in this study (age: 22.5 ± 2.3 years, body weight: 84.2 ± 11.1 kg, height: 178 ± 7 cm, training experience: 5.4 ± 1.6 years, BS one-repetition maximum [1RM]: 177 ± 22.8 kg). The experimental sessions included 2 sets of 2 BS at 110% 1RM of either ECC-CON (load distributed by half on the barbell [55%] and on weight releasers [55%]) or ECC (only eccentric phase of BS) and CTRL with no CA applied. CMJ performance, mechanical properties, and skin surface temperature were measured before and at the third, sixth, ninth, and 12th min. After each protocol, only the ECC-CON condition led to a significant increase in CMJ height after individual optimal rest time compared to pre-CA (38.1 ± 5.2 vs. 39.8 ± 5.0 cm; p = 0.003; effect size [ES] = 0.32; Δ = 4.9 ± 5.0%) with a significant rise in skin surface temperature (32.98 ± 1.24 vs. 33.69 ± 0.96°C; p = 0.006; ES = 0.62; Δ = 2.2 ± 2.6%) and no significant changes in mechanical properties of the vastus lateralis. The ECC-CON condition led to a significant acute improvement in CMJ height and an increase in front thigh skin surface temperature among powerlifters. The ECC-CON supramaximal lower limb PAPE protocol should be effectively used among males representing high levels of lower limb muscle strength (>2 × body mass).

UNLABELLED: Schizophrenia is a complex disorder characterized by altered brain functional connectivity, detectable during both task and resting state conditions using different neuroimaging methods. To this day, electroencephalography (EEG) studies have reported inconsistent results, showing both hyper- and hypo-connectivity with diverse topographical distributions. Interpretation of these findings is complicated by volume-conduction effects, where local brain activity fluctuations project simultaneously to distant scalp regions (zero-phase lag), inducing spurious inter-electrode correlations. AIM: In the present study, we explored the network dynamics of schizophrenia using a novel functional connectivity metric-corrected imaginary phase locking value (ciPLV)-which is insensitive to changes in amplitude as well as interactions at zero-phase lag. This method, which is less prone to volume conduction effects, provides a more reliable estimate of sensor-space functional network connectivity in schizophrenia. METHODS: We employed a cross-sectional design, utilizing resting state EEG recordings from two adult groups: individuals diagnosed with chronic schizophrenia (n = 30) and a control group of healthy participants (n = 30), all aged between 18 and 55 years old. RESULTS: Our observations revealed that schizophrenia is characterized by a prevalence of excess theta (4-8 Hz) power localized to centroparietal electrodes. This was accompanied by significant alterations in inter- and intra-hemispheric functional network connectivity patterns, mainly between frontotemporal regions within the theta band and frontoparietal regions within beta/gamma bands. CONCLUSIONS: Our findings suggest that patients with schizophrenia demonstrate long-range electrophysiological connectivity abnormalities that are independent of spectral power (i.e., volume conduction). Overall, distinct hemispheric differences were present in frontotemporo-parietal networks in theta and beta/gamma bands. While preliminary, these alterations could be promising new candidate biomarkers of chronic schizophrenia.

In addition to "classic" and eosinophilic subtype, chromophobe renal cell carcinoma (RCC) is well-known to demonstrate various morphological patterns including adenomatoid, microcystic, pigmented, multicystic, papillary, neuroendocrine-like, and small cell-like, all of which are important to appreciate for accurate diagnosis. Herein, we expand on a unique chromophobe RCC morphology not previously described consisting of tumor cells with extensive stromal retraction, mimicking upper urothelial tract micropapillary carcinoma (MPC). Twelve MPC-like chromophobe RCC nephrectomies were reviewed with clinicopathological features recorded; molecular testing was performed on 7 of 12 tumors. Patients were mostly men (n=10) with a mean age of 65 years. Mean tumor size was 6.4 cm with pathological stage distribution as follows: 4 (33%) T1a, 2 (17%) T1b, 1 (8%) T2b, and 3 (25%) T3a. The extent of MPC-like chromophobe RCC foci ranged from 10% to 40% (mean=26%; there was no correlation between the extent of MPC-like chromophobe RCC foci and tumor stage). Other chromophobe RCC morphological patterns were not identified. When performed, all (100%) tumors depicted prototypic chromophobe RCC staining pattern of KIT positivity/KRT7 positivity. Molecular showed 6 of 7 (86%) with multiple chromosomal losses. Clinically significant mutations were identified in NF1, TP53, FLCN (likely somatic), CHEK2, and ZFHX3 genes. Follow up available in 9 patients showed no evidence of disease (mean=23 months). Although the etiology behind the extensive stromal retraction in our tumors is unknown, this may likely be artifactual in nature. Nonetheless, it is important to include MPC-like chromophobe RCC in the spectrum of "variant" morphologies to avoid diagnostic pitfalls from micropapillary carcinoma.

BACKGROUND AND OBJECTIVES: HLA-B27 is a genetic marker associated with spondyloarthropathies, particularly ankylosing spondylitis and axial spondyloarthritis. While its prevalence varies across populations, no data exist for Slovak patients. This study aimed to determine HLA-B27 prevalence in Slovak patients with suspected spondyloarthropathies and assess differences by sex and age. METHODS: A retrospective cohort of 1,614 patients (888 females and 726 males) was analyzed for HLA-B27 status (positive/negative) using reverse hybridisation (HLA-B27 StripAssay). Statistical analyses included Pearson's Chi-square test and non-parametric Mann-Whitney U and Kruskal-Wallis tests for sex- and age-related differences. RESULTS: HLA-B27 positivity was 20.57%, with a higher proportion in males (23.28%) than females (18.36%, p = 0.0177). The less than 20 age group had the highest absolute number of positive cases (126 cases; 17.80%), while the 21-40 group had the highest relative positivity (119 cases; 29.38%). The lowest positivity was in the more than 61 age group (17 cases; 13.08%), though age distribution differences were not statistically significant (p = 0.7765). Positivity varies across diagnoses, peaking in musculoskeletal (M) and eye disorders (H), where it exceeds 29%. CONCLUSION: HLA-B27 positivity is strongly associated with rheumatologic and ophthalmologic conditions and exhibits age- and sex-related variability. These findings emphasize the diagnostic significance of HLA-B27 testing in Slovak patients, especially for early detection and management of spondyloarthropathies. Further research on HLA-B27 variability and its clinical implications is needed to optimize diagnostic strategies and patient care.
