Background: The Performance Indicator of Colonic Intubation (PICI) is a new measure of high-quality colonic intubation. Adequate PICI was defined as cecal intubation without significant discomfort and use of minimal sedation. This study assessed achievement of PICI within the Dutch colorectal cancer (CRC) screening program, and determined the association between PICI and adenoma detection rate (ADR). PICI achievement when using the Dutch median midazolam dose was also assessed.
Methods: This retrospective study was conducted within the Dutch fecal immunochemical test-based CRC screening program. Colonoscopy and pathology data were prospectively collected in a national database. Data between January 2016 through January 2018 were analyzed. Adequate PICI was defined as successful cecal intubation, Gloucester Comfort Scale (GCS) of 1 - 3, and use of ≤ 2.5 mg midazolam.
Results: 107 328 colonoscopies were performed during the study period. Adequate PICI was achieved in 49 500 colonoscopies (46.1 %). In colonoscopies with inadequate PICI, inadequacy was due to higher sedation doses in 87.8 %. Adequate PICI was associated with higher ADR (odds ratio 1.16, 95 % confidence interval 1.12 - 1.20). When using a cutoff of 5 mg midazolam, median dose in this Dutch population, adequate PICI was achieved in 95 410 colonoscopies (88.9 %).
Conclusion: PICI appeared to be heavily dependent on sedation practice. Because of wide variation in sedation practice between individual endoscopists and countries, the benefit of PICI as a quality indicator is limited.

Background: The etiology of preeclampsia (PE) may be associated with the increased of production of reactive species and decreased antioxidant activity of enzymes. Inadequate intake of Zn can affect gestational health due to its biological functions, such as its role in the antioxidant defense system. The study aimed to assess the nutritional status of Zn and antioxidant enzymes in postpartum women and its correlation with neonatal outcomes.

Tons of crude oil were found on the Brazilian coast in 2019, and studies assessing its chemical composition are still scarce. This study aimed to develop a new and simple technique of cold vapor generation using infrared irradiation coupled with atomic absorption spectrometry to determine mercury content in sediments contaminated by crude oil. Experimental conditions were evaluated, including formic acid concentration, reactor temperature, and carrier gas flow rate.

Article Synopsis
- Adequate housing significantly reduces the risk of severe diarrhea, a critical health issue in low- and middle-income countries.
- The study focused on the connection between housing features and severe diarrhea outcomes in Brazilian municipalities, assessing data from 2000 to 2012 for 5,570 municipalities.
- Results showed that under-5 children’s diarrhea deaths were most strongly influenced by housing factors, particularly waste management, which outperformed traditional WASH elements in predicting gastrointestinal health outcomes.

The increasing worries by the inadequate use of energy and the preservation of nature are promoting an increasing interest in the production of biolubricants. After discussing the necessity of producing biolubricants, this review focuses on the production of these interesting molecules through the use of lipases, discussing the different possibilities (esterification of free fatty acids, hydroesterification or transesterification of oils and fats, transesterification of biodiesel with more adequate alcohols, estolides production, modification of fatty acids). The utilization of discarded substrates has special interest due to the double positive ecological impact (e.
