Cervical cancer prevention: Feasibility of self-sampling and HPV testing in rural and urban areas of Bolivia: An observational study.

BACKGROUND: Cervical cancer is a major health problem in Latin America. In 2019, the Italian Agency for Development Cooperation (La Paz regional site) conducted a pilot study to estimate the prevalence of high-risk human papillomavirus (HPV) and the feasibility of HPV screening in Bolivia through self-sampling and portable and transportable laboratory instruments for HPV testing in urban and rural areas. METHODS: Women aged 20-65 years from La Paz (urban area), Toro Toro (rural area), and Acasio (rural area) were enrolled in local public health centers between Dec 1, 2019, and June 30, 2021. Self-sampling was carried out with the Viba-Brush system (Rovers, Oss, Netherlands) and samples were preserved in ThinPrep containers (Hologic Corporation, San Diego, CA, USA). The GeneXpert system (Cepheid, Sunnyvale, CA, USA) for high-risk HPV testing detects HPV E6 and E7 DNA via real-time PCR in a mobile system of easy execution requiring minimal manual intervention. The system provides results in about 1 h. The hr- HPV prevalence data, overall and partial genotyping, were analyzed considering the following age groups: 20-34, 35-44, and 45-65 years old. FINDINGS: 2168 women were enrolled: 614 (28.3%) in La Paz, 743 (34.3%) in Toro Toro, and 811 (37.4%) in Acasio. Only one sample was collected from each participant. 2043 (94.2%) of 2168 samples were adequate for HPV testing. 255 (12.5%) samples were positive for high-risk HPV. Comparing the urban area (La Paz) versus rural combined areas (Acasio+Toro Toro), using a logistic model, the HPV total rate was statistically significantly higher in the city of La Paz (15.0% vs 11.4%; OR:1.37;95% CI: 1.04-1.80). Furthermore, the HPV prevalence was declining by age, and the urban/rural odds ratio was 1.50; (95% IC 1.13-19). The overall HPV 16 positivity was 2.7% (55/2043) and for HPV 18/45 was 1.8% (37/2043) without any statistically significant differences between the three BHU enrolling centers. Only the prevalence of HPV group '39/56/66/68' was significantly higher in La Paz (p<0,001) in comparison to Acasio and Toro Toro. INTERPRETATION: The total and age-adjusted prevalence of high-risk HPV infection in rural and urban areas in Bolivia, as measured with a validated test for screening, is similar to that observed in Europe and the USA. Our study shows that a screening protocol for HPV testing with self-sampling would be feasible in urban and rural areas in Bolivia, and that the reported high occurrence of cervical cancer in Bolivia is not related to a higher rate of high-risk HPV infections. Carrying out HPV tests locally avoids the issues associated with transportation and storage of the collected material and allows the participant to wait in the clinic for the test result, overcoming the very long response time for screening test in Bolivia.

Near-infrared system's efficiency for peripheral intravenous cannulation in a level III neonatal intensive care unit: a cross-sectional study.

Venipuncture is a painful and invasive procedure for hospitalised newborns and represents a challenge for neonatal healthcare professionals. This study evaluated the most efficient cannulation method based on the proportion of success at the first attempt, standard care or near-infrared (NIR) device use, and pain assessment. An observational study with two arms was conducted in the neonatal intensive care unit (NICU) of a tertiary-care university hospital in Italy. All newborns undergoing peripheral vein cannulation and only nurses with more than 5 years of professional experience in the NICU were eligible for the first arm. Only newborns with a body weight of >2500 g at cannulation and all nurses working in the NICU were involved in the second arm. In the first arm of the study, no statistically significant differences between the NIR and control groups were found in terms of proportion of successful at the first attempt 60.6% (confidence interval [CI] 95%: 48.8; 72.4) vs. 56.1% (CI 95%: 44.1; 68.0) and the mean premature infant pain profile score 6.3 (CI 95%: 5.4-7.1) vs. 5.8 (CI 95%: 5.0-6.6). In the second arm, only among less experienced nurses (<1 year), we observed a significant increase in the proportion of success in the NIR group compared with the control group, nearly tripling the success rate (72.7% [54.1; 91.3] vs. 23.1% [0.2; 46.0]).  Conclusion: This study reported no differences between the NIR and control groups. The results also suggest that using a NIR device may be advantageous for healthcare professionals with less experience during first-time cannulation. What is Known: • Venipuncture is a painful procedure commonly used to place a peripheral venous catheter for administering nutrients or drugs. • Near-infrared light facilitates the visualisation of veins and consequently, the performance of cannulation in the paediatric population. What is New: • The near-infrared light device was not associated with fewer attempts and a lower premature infant pain profile score in placing venous access in newborns than the traditional method. • The near-infrared light device could help nurses with less professional experience place a peripheral venous catheter.

Robotic Therapy: Cost, Accuracy, and Times. New Challenges in the Neonatal Intensive Care Unit.

Background: The medication process in the Neonatal Intensive Care Unit (NICU), can be challenging in terms of costs, time, and the risk of errors. Newborns, especially if born preterm, are more vulnerable to medication errors than adults. Recently, robotic medication compounding has reportedly improved the safety and efficiency of the therapeutic process. In this study, we analyze the advantages of using the I.V. Station® system in our NICU, compared to the manual preparation of injectable drugs in terms of accuracy, cost, and time. Method: An in vitro experimental controlled study was conducted to analyze 10 injectable powdered or liquid drugs. Accuracy was calculated within a 5% difference of the bottle weight during different stages of preparation (reconstitution, dilution, and final product). The overall cost of manual and automated preparations were calculated and compared. Descriptive statistics for each step of the process are presented as mean ± standard deviation or median (range). Results: The median error observed during reconstitution, dilution, and final therapy of the drugs prepared by the I.V. Station® ranged within ±5% accuracy, with narrower ranges of error compared to those prepared manually. With increasing preparations, the I.V. Station® consumed less materials, reduced costs, decreased preparation time, and optimized the medication process, unlike the manual method. In the 10 drugs analyzed, the time saved from using the I.V. Station® ranged from 16 s for acyclovir to 2 h 57 min for teicoplanin, and cost savings varied from 8% for ampicillin to 66% for teicoplanin. These advantages are also capable of continually improving as the total amount of final product increases. Conclusions: The I.V. Station® improved the therapeutic process in our NICU. The benefits included increased precision in drug preparation, improved safety, lowered cost, and saved time. These advantages are particularly important in areas such as the NICU, where the I.V. Station® could improve the delivery of the high complexity of care and a large amount of intravenous therapy typically required. In addition, these benefits may lead to the reduction in medication errors and improve patient and family care; however, additional studies will be required to confirm this hypothesis.
