15-25 gadīgo zināšanas par cilvēka papilomas vīrusu
2022
Vispārīga informācija:Cilvēka papilomas vīruss (HPV) ir viens no visizplatītākā seksuāli transmisīvā slimība visā pasaulē. Infekcijas sekas var būt maksts, vulvas, dzemdes kakla, dzimumlocekļa, anālā rajona, mutes dobuma un rīkles vēzis, kā arī kārpas dzimumorgānu rajonā. Infekciju veicinošie faktori ir dzimumakts bez prezervatīva, liels dzimumpartneru skaits, agrīns pirmais dzimumakts un smēķēšana. Vissvarīgākais primārais profilakses pasākums ir vakcinācija pret HPV. Mērķis:Darba objektīvais mērķis ir novērtēt 15-25 gadi vecu cilvēku zināšanas un izpratni par HPV un atrast ietekmējošos faktorus, lai nākotnē radītu mērķtiecīgāku izskaidrošanu. Materiāli un metodes:200 dalībnieki aizpildīja…

Augsta riska cilvēka papilomas vīrusa detekcija nieres transplantāta recipientēm ar imūnsistēmas supresiju dinamikā
2018
Šī darba ietvaros ar dāžadām testēšanas metodēm detektēja augsta riska cilvēka papilomas vīrusa (HPV) klātbūtni nieres transplantāta recipienšu vidū, kā arī pētīja vīrusa slodzes un detektējamības izmaiņas periodā no 2 nedēļām līdz 1 gadam pēc transplantācijas. Pētījumā tika iesaistītas 35 nieres transplantāta recipientes un 79 praktiski veselas sievietes kā kontroles grupa. Pētījumā tika izmantotas dzemdes kakla iztriepes un perifērās asinis plazmas izdalīšanai. Iegūtos rezultātus salīdzināja ar kontroles grupu, lai spriestu par imūnsupresēto indivīdu paaugstināto risku HPV infekcijai. Dzemdes kakla iztriepju šūnu suspensijās gan recipienšu, gan kotroles grupas sievietēm HPV DNS sākotnēji …
Human papillomaviruses in oral carcinoma and oral potentially malignant disorders: a systematic review.
2011
Human papillomavirus (HPV) in oral carcinoma (OSCC) and potentially malignant disorders (OPMD) is controversial. The primary aim was to calculate pooled risk estimates for the association of HPV with OSCC and OPMD when compared with healthy oral mucosa as controls. We also examined the effects of sampling techniques on HPV detection rates. Methods: Systematic review was performed using PubMed (January 1966-September 2010) and EMBASE (January 1990-September 2010). Eligible studies included randomized controlled, cohort and cross-sectional studies. Pooled data were analysed by calculating odds ratios, using a random effects model. Risk of bias was based on characteristics of study group, appr…
Hypoxia inducible factor-1 alpha expression is increased in infected positive HPV16 DNA oral squamous cell carcinoma and positively associated with H…
2011
Abstract Background There is increasing evidence for the role of High Risk (HR) Human PapillomaVirus (HPV) in the pathogenesis of Oral Squamous Cell Carcinoma (OSCC). The E6 and E7 oncogenes from HR HPVs are responsible for the deregulation of p53 and pRB proteins involved in cell cycle and apoptotic pathways. In cell lines experiments, the HPV E7 protein seems to be able to enhance Hypoxia Inducible Factor-1 alpha (HIF-1α) activity, normally involved in the response to hypoxia and able to enhance angiogenesis. Results We studied tumor specimens from 62 OSCC; a higher prevalence of tumors in TNM stage II and also in pT2 class between OSCC infected positive HPV16 DNA than non-infected ones w…
Factors Associated with HPV Vaccine Refusal among Young Adult Women after Ten Years of Vaccine Implementation
2018
In Italy, the Human Papillomavirus (HPV) vaccination was implemented for twelve years old girls in 2007, but its coverage was lower than the recommended level. Sicily is one of the Italian administrative regions with lower vaccination coverage, with a value of 59% for those born in 1996 increasing to 62% coverage for those born in 1999. The aim of the study was to investigate factors associated with the refusal of HPV vaccination among young adult women of Palermo, Italy. The study was approved by the Ethics Committee of the Policlinico “Paolo Giaccone” Hospital (Palermo 1) and the questionnaire was validated in a convenience sample representing 10% of the young women. A cross-s…
Facilitators and barriers HPV unvaccinated girls after 5 years of program implementation
2014
Understanding perceptions and characteristics of human papillomavirus (HPV) vaccinated and non-vaccinated girls can inform communication activities and vaccine delivery strategies. The purpose of this study was to evaluate knowledge and factors associated with HPV unvaccinated girls after five years of vaccination program implementation in Sicily, an Italian region with low vaccination coverage (<50.0%). A cross-sectional study was conducted through a questionnaire designed to assess knowledge and vaccination status of girls of 1997, 1998, 1999, and 2000 birth cohorts. The sample consisted of 350 girls who attended three high schools. Multivariable logistic regression analysis was conducted…
Drivers for human papillomavirus vaccination in Valencia (Spain)
2018
Objective: To describe the drivers associated with HPV vaccination in adolescent girls and their parent's opinion on the vaccine. Methods: We conducted an observational and cross-sectional study on adolescent girls and their parents in Valencia (Spain), between September 2011 and June 2012. A consultation was made at a random sample of schools of the 14-year-old girls that should have received the vaccine in the free vaccination programme. We ran a personal survey on knowledge and attitudes regarding HPV infection and the vaccine. A binary logistic regression model was performed to determine which factors were most associated with vaccination. Results: The survey was run on a binomial of 1,…
Imaging-guided interventions modulating portal venous flow: Evidence and controversies
2021
Portal hypertension is defined by an increase in the portosystemic venous gradient. In most cases, increased resistance to portal blood flow is the initial cause of elevated portal pressure. More than 90% of cases of portal hypertension are estimated to be due to advanced chronic liver disease or cirrhosis. Transjugular intrahepatic portosystemic shunts, a non-pharmacological treatment for portal hypertension, involve the placement of a stent between the portal vein and the hepatic vein or inferior vena cava which helps bypass hepatic resistance. Portal hypertension may also be a result of extrahepatic portal vein thrombosis or compression. In these cases, percutaneous portal vein recanalis…
Cannabinoids, TRPV and nitric oxide: the three ring circus of neuronal excitability
2019
Endocannabinoid system is considered a relevant player in the regulation of neuronal excitability, since it contributes to maintaining the balance of the synaptic ionic milieu. Perturbations to bioelectric conductances have been implicated in the pathophysiological processes leading to hyperexcitability and epileptic seizures. Cannabinoid influence on neurosignalling is exerted on classic receptor-mediated mechanisms or on further molecular targets. Among these, transient receptor potential vanilloid (TRPV) are ionic channels modulated by cannabinoids that are involved in the transduction of a plethora of stimuli and trigger fundamental downstream pathways in the post-synaptic site. In this…
