RESUMO
BACKGROUND: Cervical cancer is the fourth most common cancer in the world. A raised incidence and mortality parallel a low participation rate in screening, namely screening in poor countries and among specific populations of developed countries. Cervical or vaginal self-sampling may increase adherence to screening due to its low costs and elevated sensibility and specificity. Our main goal was to compare self-sampling with physician sampling and to evaluate the participation rate of women formerly non-adherent to cervical cancer screening. STUDY DESIGN: We identified relevant studies from PubMed. Studies were eligible for inclusion if they fulfilled the following criteria: women aged between 16 and 80 years, poor and developed countries that use self-sampling, women with a low participation rate in screening and studies published since 2013. After fully reading the articles, data were extracted to an Excel sheet to -display all relevant information in an organized manner. -Results: We identified 18 studies, which altogether enrolled 22,118 women. Self-sampling and physician sampling are quite similar regarding the HPV detection rate. Women have a low participation rate mainly because of limited access to health services, religious and culture beliefs, and lack of time due to several demanding tasks in daily life. Self-sampling shows a significant increase in acceptability and preference compared to physician sampling. CONCLUSION: Self-sampling is a reliable method to involve women in opportunistic or organized screening programs for cervical cancer prevention.

AIM OF THE STUDY: To determine the hepatic interferon γ (IFN-γ) and tumor necrosis factor α (TNF-α) levels in infants with neonatal cholestasis (NC) and associated cytomegalovirus (CMV) infection. MATERIAL AND METHODS: This study was conducted in 21 infants with NC over a period of 6 months from June 2017 to December 2017 to determine the hepatic IFN-γ and TNF-α levels in infants with NC and associated CMV infection. RESULTS: IFN-γ levels were positive in 16 (80%), low positive in 3 (16%) and negative in 1 (5%) patients. High positive and positive TNF-α levels were seen in 9 (56.3%) patients with positive liver CMV PCR and low positive levels were seen in 7 (43.7%) patients with positive liver CMV PCR (odds ratio [OR] = 2.6). Positive IFN-γ was present in 13 (81.3%) patients with positive liver CMV PCR and low positive or negative IFN-γ was seen in 3 (18.7%) patients with positive liver CMV PCR (OR = 2.2). Six (60%) patients with positive or high positive TNF-α levels in liver tissue had biliary atresia (BA) whereas 7 (77.7%) with low positive TNF-α levels had non-BA neonatal hepatitis (OR = 5.25). Six (37.5%) patients with positive IFN-γ had BA whereas 2 (50%) patients with low positive or negative IFN-γ had BA (OR = 0.6). CONCLUSIONS: There is high prevalence of CMV in liver tissues in patients with NC and elevated TNF-α and IFN-γ levels are seen in these patients. Elevated TNF-α is also seen in patients with BA. The association of elevated TNF-α, BA and CMV infection needs to be evaluated further.
