This article discusses the controversial issues of cytological screening for cervical cancer, including the use of liquid-based cytology and automated screening systems, high-risk human papillomavirus testing, and organizational issues of screening and staff training.

Human papillomavirus is associated with several anogenital and oropharyngeal lesions, including warts, premalignant lesions, and cancer. There are specific groups that were identified as high-risk groups for anal squamous cell carcinoma and anal human papillomavirus infection, namely HIV-positive patients, men who have sex with men, women with genital tract neoplasia, and solid organ transplant recipients. Condylomas have classically been considered to be a benign lesion, with an exception made for the Buschke-Loewenstein tumor, but several publications have shown that a high percentage of condylomas harbor high-grade lesions. Due to the similarities between anal and cervical carcinogenesis, anal cancer screening based on anal cytology and referral to high-resolution anoscopy, in case of abnormalities, have been advocated. Testing for anal human papillomavirus is not routinely done in anal cancer screening, because of the very high prevalence in high-risk populations. The large majority of anal cancers are squamous cell carcinomas (SCC), and around 90% are attributed to human papillomavirus. Human papillomavirus positivity in anal SCC seems to have a prognostic value, with better survival in those patients with positive tumors. Prophylactic vaccination has been shown to be important for prevention of anal human papillomavirus-related lesions.

The hereby article discusses the issues related to the existing or required support given by the State to enterprises in order to provide them conditions to innovate. Neoclassical economy puts an emphasis to the price mechanism as a decision making effective tool, but enterprises meet many barriers in creating and introducing innovation, like high cost, high risk or lack of demand for innovation. These phenomena tend to inhibit innovation of enterprises. This means that market is not an efficient mechanism for innovation activity of enterprises, and its imperfections provoke the State’s intervention. The goal of the article is to shape the objectives of State’s impact on decisions of innovative enterprises. Research method is the critical literature review and public data on State’s support on business R&D analysis. The research results show State’s support for both – incremental and radical innovation, which proves that innovative activity of enterprises is far from being a spontaneous, market-based process.

Background/Aim. In patients with premalignant cervical lesions, human papillomavirus (HPV) infection, at any moment, may be spontaneously eliminated, or may persist or transform cervical epithelium from a lower to a higher degree. Due to that, it is necessary to wisely select the patients who are at high risk of cancer development. The aim of the study was to establish the interdependence between a suspicious Papanicolaou (Pap) test and colposcopy with the infection caused by high-risk genotypes of human papillomavirus and the presence of premalignant cervical lesions. Methods. This prospective study used cytological, colposcopy, real-time polymerase chain reaction (PCR) of high-risk genotypes of human papillomavirus and histopathological analysis of cervical biopsy specimen. Out of 2,578 female patients sent to cytological analyses in Clinical Center of Montenegro, during 2012, 2013 and 2014, the study included 80 women who had to submit their biopsy specimens due to a suspicious Pap test and atypical colposcopy results. Results. In the group of 80 (3.1%; n = 80/2,578) of the selected female patients with suspicious Pap test and colposcopy, 2/3 or 56 (70%) of them had cervicitis, and 1/3 or 24 (30%) had cervical intraepithelial neoplasia. The most common type in cervical intraepithelial neoplasia was HPV16 in 8 female patients, ie 61.53% out of the number of infected, or 33.33% out of the total number of premalignant lesions. Conclusion. Patients with suspicious Papanicolaou test, colposcopy results and infection which is caused by high-risk HPV infection (HPV 16 in particular) often have premalignant cervical lesions. In these cases, histopathological confirmation of lesions is mandatory, since it serves as a definitive diagnostic procedure.

This research study provides the first comprehensive and critical literature review of K–12 Filipina/o American curricula found in formal and informal educational settings. Thirty-three Filipina/o American curricula representing a diverse array of authors, audiences, content, and pedagogical approaches were reviewed. The authors of this study developed a “Critical Framework of Review” rooted in critical pedagogy in order to analyze the historical development of Filipina/o American curricula along with an analysis of major topics, concepts, guiding theoretical frameworks, pedagogical approaches, and outcomes. The review concludes with a discussion and summary of the overarching themes of Filipina/o curricular content, instruction, and impact gained from this study and recommendations for the application, development, distribution, and research of more Filipina/o American K–12 curriculum resources.
