Morphological analysis of intracranial pressure (ICP) pulse waveforms provides indirect information on cerebrospinal compliance, which might be reduced by space-occupying lesions but also by intracranial hypertension and aging. This study investigates the impact of age and mean ICP on the shape and amplitude of ICP pulse waveform in traumatic brain injury (TBI). Additionally, it explores the association between morphological parameters and mortality after TBI.

The relationship between structural and hemodynamic parameters in patients with primary open angle glaucoma is strongest in the temporal region of the optic nerve.

Antibiotic use is the main driver of bacterial antimicrobial resistance. Urinary tract infections (UTIs), for which antibiotics are often prescribed, are among the most common infections among residents in nursing homes. This study aimed to estimate and compare the appropriateness of antibiotic use for suspected UTIs among nursing home residents across five European countries. Both the decision to treat and the choice of antibiotics used were explored.

Objectives: This cross-sectional observational study aims to identify the prevalence of musculoskeletal disorders among Lithuanian dentists and dental hygienists and determine the most affected body areas. Material and Methods: An anonymous survey was carried out from October 20, 2024, to December 5, 2024. The questionnaire was distributed online to Lithuanian specialists - dentists and oral hygienists. A total of 382 professionals were included in this survey. Chi-square test, its degrees of freedom was used for the analysis of variables. Results: The study involved 382 participants who reported experiencing pain in the neck (65.7%), shoulders (59.7%), and lower back (58.1%) in the past 12 months, while only 4.5% did not experience any discomfort. Based on the study data, 19.4% of respondents were unable to perform their regular work due to problems related to pain in certain areas during the last 12 months. In addition, 49.5% of specialists had never consulted a physiotherapist or doctor about their condition during the past year. As many as 20.7% of respondents stated that they were completely physically inactive, and 18.1% engaged in low-intensity physical activity. Conclusions: Overall, dentists and dental hygienists in Lithuania face a significant prevalence of work-related musculoskeletal disorders in their profession. Considering the magnitude of this issue, it is essential to implement university-level preventive education programs that provide dental professionals with comprehensive ergonomic knowledge.

Lėtinis atrofinis gastritas – tai ilgalaikio lėtinio skrandžio uždegimo sąlygota skrandžio gleivinės atrofija. Atrofinio gastrito fone vystosi metaplazija žarninio tipo epiteliu, vėliau epitelio displazija ir skrandžio vėžys. Atrofija ir žarninė metaplazija apibūdinamos kaip ikivėžinės būklės. Skrandžio gleivinės atrofija ir žarninė metaplazija yra dažnesnės šalyse, kuriose yra didelis sergamumas skrandžio vėžiu. Atrofinis gastritas laikomas ikivėžine liga, tačiau nėra visiškai aišku, ar galimas atrofijos proceso sustabdymas, ar tai leidžia apsaugoti nuo skrandžio vėžio.

Voice disorders (hoarseness) are a common condition manifesting in almost 10% of the population. The causes of hoarseness can be related to common respiratory diseases and/or to vocal fatigue caused by vocal overload, however it can also be related to functional, behavioral, neurologic factors and both benign and malignant laryngeal tumors. Hoarseness can also be an early symptom of laryngeal cancer. The VoiceScreen app requires the user to perform two simple tasks: 1). Sustain a vowel [a:] sound for 4 seconds, 2) Read the provided sentence. The users’ voice is recorded and then analyzed extracting six acoustic voice function parameters which are then weighted and merged together to provide the user with the Acoustic Voice Quality Index (AVQI) of his/her voice. The value of AVQI as a clinical marker of overall voice quality has already been proven across multiple studies revealing adequate diagnostic accuracy. The AVQI values do not depend on gender and age. The VoiceScreen app calculates and displays the value of AVQI and also provides the user with recommendations based on the test results. The provided recommendations should be taken as guidance on what to do next to help the user’s voice. [...].

Vidutinis trombocitų tūris (MPV-mean platelet volume) yra bendrojo kraujo tyrimo metu nustatomas rodiklis, kuris apibūdina vidutinį trombocitų dydį ir gali būti susijęs su uždegimu bei tromboze. Didesnis MPV yra susijęs su didesne išeminio insulto, ūminio miokardo infarkto, giliųjų venų trombozės bei plaučių arterijų trombembolijos rizika. Tyrimo tikslas - nustatyti MPV sąsajas su lėtiniu prieširdžių virpėjimu (PV) ir periferinių arterijų liga (PAL). Į tyrimą įtraukta 180 pacientų, kurie suskirstyti į grupes: sergančių lėtiniu PV pacientų ir pacientų, kuriems registruotas sinusinis ritmas. Visiems tiriamiesiems apskaičiuotas kulkšnies-žasto indeksas (KŽI), sistolinio arterinio kraujo spaudimo kojose matavimui naudotas 5-MHz dopleris. PAL diagnozuota, kai KŽI gautas <0,9. MPV reikšmės buvo didesnės pacientams sergantiems lėtiniu PV (kontrolinėje grupėje 8,635±1,476 fl, tiriamojoje grupėje 9,131±1,202 fl) (p=0,015). Pacientai, kuriems nustatytas KŽI<0,9 ir MPV>8,55 fl, dažniau sirgo lėtiniu PV nei pacientai, kurių KŽI>0,9, o MPV<8,55 fl (p=0,001). Didesnis MPV buvo susijęs su didesne PAL tikimybe (ŠS 1,608, 95% PI 1,243 – 2,081) (p=0,001) nepriklausomai nuo lyties ir amžiaus (koreguotas ŠS 1,612, 95% PI 1,248 – 2,098) (p=0,001). PAL sergantiems pacientams buvo nustatytas didesnis MPV, kritinė MPV reikšmė - 8,55 fl. MPV reikšmei esant 8,55 fl, rodiklio jautrumas PAL nustatymui buvo 76%, o specifiškumas – 61%.

Mezenterinis panikulitas (MP) – reta patologija, apibūdinama kaip lėtinis, nespecifinis žarnyno pasaito riebalinio audinio uždegimas. Ligos paplitimas – 0,16-2,5 proc. Vyrams ši patologija dažnesnė nei moterims, santykis – 2-3:1. Pagrindinis patogeninis mechanizmas yra nespecifinis uždegiminis atsakas į skirtingus etiologiniuis faktorius, tačiau tikslios priežastys iki šiol nepakankamai ištirtos. Histologiškai išskiriamos trys ligos progresavimo stadijos. Dažniausiai ši liga yra besimptomė ir nustatoma atsitiktinai, kitais atvejais simptomai būna nespecifiniai ir kintami. Kompiuterinė tomografija yra pagrindinis tyrimas MP diagnozei nustatyti. Tiksliai diagnozei patvirtinti reikalinga ekscizinė biopsija ir histologinis tyrimas. Nėra visuotinai priimto sutarimo, kokį gydymą skirti, rekomenduojama gydyti imunomoduliatoriais, priešuždegiminiais, antifibrotiniais vaistais. Chirurginis gydymas gali būti taikomas, jei konservatyvusis gydymas neveiksmingas arba yra gyvybei pavojingų komplikacijų.

Mokomoji knyga skirta pirmojo kurso Veterinarinės medicinos studentams, studijuojantiems „Atramos ir judėjimo“ modulį. Osteologija – mokslas apie kaulus – sudaro didelę šio modulio dalį. Šia mokomąja knyga galės naudotis ir studentai, studijuojantys modulio „Gyvybės mokslai – 1“ bendrosios anatomijos dalį. Knyga taip pat bus naudinga aukštesniojo kurso studentams, studijuojantiems chirurgijos ir ortopedijos studijų dalykus, žemės ūkio srities magistrantams bei doktorantams, veterinarijos gydytojams. Veterinarinės anatomijos literatūros studijoms lietuvių kalba labai trūksta, o vos keli išleisti vadovėliai mena praeitą šimtmetį. Manome, kad šis leidinys atitiks šiuolaikinės veterinarinės medicinos poreikius savo turiniu, struktūra bei iliustracijomis ir padės studentams geriau įsisavinti veterinarinės osteologijos žinias. Šiame naujame leidinyje išsamiai apžvelgta mėsėdžių griaučių struktūra, kuri iki šiol nebuvo labai akcentuojama, tačiau laikui bėgant tapo viena aktualiausių ir labiausiai tiriamų sričių veterinarinėje praktikoje. Studentams osteologija yra vienas pirmųjų prisilietimų prie veterinarinės anatomijos mokslo, todėl svarbu užtikrinti, kad šis įspūdis neišblėstų ir motyvuotų toliau semtis anatomijos žinių. Knygoje pateikiama išsami ašinių ir pridėtinių griaučių anatominė sandara, nagrinėjami visų aktualiausių naminių gyvūnų – atrajotojų (galvijų, avių, ožkų), arklių, kiaulių, mėsėdžių (šunų ir kačių) rūšiniai skirtumai. Knyga gausiai iliustruota geros kokybės nuotraukomis, kurių didžioji dalis yra nufotografuota pačių autorių. Pateikiami anatomijos terminai (lietuvių ir lotynų kalbomis) suderinti su „Veterinarinės anatomijos, histologijos ir embriologijos terminų žodynu“ (2013).

Aims/hypothesis The aims of this study were to provide a contemporary picture of mortality and causes of death in Europe following a diagnosis of type 1 diabetes made before the 15th birthday, and to examine excess mortality by country for possible links to incidence level or national prosperity. Methods Thirteen population-based EURODIAB registers in 12 countries followed-up 28,887 children diagnosed since 1989, either by record linkage to population registers or through contact with doctors providing care. Results There were 141 deaths in the cohort during 219,061 person-years of follow-up compared with 69.1 deaths expected from national mortality rates, a standardised mortality ratio (SMR) of 2.0 (95% CI 1.7–2.4). The SMR varied from 0 to 4.7 between countries, but showed little relationship with the country’s incidence rate or gross domestic product (US$ per capita). The SMR did not change significantly with attained age, calendar period or time since diagnosis. The female SMR (2.7; 95% CI 2.0–3.5) was greater than the male SMR (1.8; 95% CI 1.4–2.2), although absolute numbers of excess deaths were similar in the two sexes. One-third of deaths were classified as directly attributable to diabetes (many with mention of ketoacidosis) and half were unrelated to diabetes. There was a non-significant excess of accidental/violent deaths (48 observed vs 40.7 expected; SMR 1.2; 95% CI 0.9–1.6) but little excess in suicides (11 observed, 10.2 expected; SMR 1.1; 95% CI 0.5–1.9). Conclusions/interpretation Before the onset of late complications, significant excess mortality existed following the diagnosis of type 1 diabetes in childhood, even in recent years. Variation between countries in this excess could not be explained.

Chemical analysis of spice, aromatic plants at different vegetation stages can serve for the optimal collection of plant raw material revealing the period when the plant possesses the highest biological activity and accumulates the highest content of biologically active compounds, which could be used in pharmacy, medicine, food or cosmetic industry [1]. The aim of this study was to investigate the qualitative and quantitative composition of essential oils obtained from A. absinthium during different vegetation stages. The object of investigation was Artemisia absinthium L. a perennial medicinal, aromatic plant of Asteraceae (Bercht. & J. Presl) family. A. absinthium is widely used in the Lithuanian folk medicine mainly for stomachic and anthelmintic activity, also for healing gall-bladder and kidneys diseases, against insomnia, diarrhea [3, 5, 6, 7]. Raw material of A. absinthium was collected during different vegetation stages of vegetation cycle in Spice − Melliferous plants collection ex situ of Botanical Garden at Vytautas Magnus University in 2018. Five stages have been separated: growth and leaf production, flower bud development, beginning of the flowering, massive flowering, end of the flowering [4]. The essential oils have been extracted by hydrodistillation method and analysed by the chromatographic techniques in the gas phase and chromatography in gas phase coupled with mass spectrometry (GC/MS) so as to determine their chemical composition. The percentage composition of the essential oils was computed from GC peak areas without correction factors. Qualitative analysis was based on a comparison of retention times, indexes and mass spectra with the corresponding data in the literature [2] and computer mass spectra libraries. There were studied 5 samples of A. absinthium considering different vegetation stages. A total of 81 different compounds were found in the essential oils. The data showed the...[...].

Heat shock protein 90 (Hsp90) is a molecular chaperone with over 200 identified client proteins. This chaperone protein is crucial for protein folding and stabillization and interfere in many pathways of cancer cells, therefore it is a potential target for anticancer therapy. Hsp90 inhibitors bind to the N-terminal ATP domain of Hsp90, and several of them have entered clinical trials. Recent studies show that Hsp90 inhibitors in combination with clinically used chemotherapeutic agents may act synergistically, therefore such effect can reduce the dose and toxicity of used drugs, and minimize or delay the induction of drug resistance [1]. The aim of our study was to evaluate activity of different combinations of two Hsp90 inhibitors (ICPD47 and ICPD62) and three anticancer agents (gemcitabine, 5fluorouracil and doxorubicin) against pancreatic cancer cells. The effect of Hsp90 inhibitors, other agents and different combinations on cell viability was evaluated by MTT assay in two pancreatic cancer cell lines: MIA PaCa-2 and Panc-1. The type of combination effect was determined by calculating combination index (CI), using CompuSyn software based on Chou-Talalay method [2]. Synergism was considered when CI < 1, antagonism when CI > 1, and CI value of 1 defined an additive effect of the drug combination. Results. Among tested Hsp90 inhibitors ICPD62 had the greatest effect on cell viability (EC50 values after 72 h on MIA PaCa-2 and Panc-1 were 0.446 ± 0.06 µM and 0.41 ± 0.08 µM, respectively) and among other anticancer agents doxorubicin showed the greatest effect on cell viability (EC50 values after 72 h on MIA PaCa-2 and Panc-1 were 0.076 ± 0.03 µM and 0.074 ± 0.02 µM, respectively). The combination of ICPD47 and gemcitabine with concentration ratio 5:1, showed the greatest synergistic activity in MIA PaCa-2 cell line (CI = 0.192, when fa = 0.5), and the combination of ICPD62 and gemcitabine with concentration rat[...].
