Flow cell for high throughput Raman spectroscopy of non-transparent solutions.

This work introduces a high-throughput setup for Raman analysis of various flowing fluids, both transparent and non-transparent. The setup employs a microfluidic cell, used with an external optical setup, to control the sample flow's position and dimensions 3-dimensional hydrodynamic focusing. This approach, in contrast to the prevalent use of fused silica capillaries, reduces the risk of sample photodegradation and boosts measurement efficiency, enhancing overall system throughput.

How "Light" Is "Light Smoking"? On the Cognitive Power of Nicotine Dependence.

In recent years, habits related to smoking have been changing. An increasing portion of light/occasional smokers tend to define themselves as non-smokers, leading to an incorrect perception of the risks that smoking even a few cigarettes can entail. In this study, we investigated the nicotine-induced cognitive distortion in young, higher-education students with low/moderate dependence (as indexed by the Fagerstrom questionnaire).

Fear of donation-related stimuli across different levels of donation experience and types of donation (whole-blood and plasma): A cross-sectional study in Italian donors.

Background: Donation-related fears are prevalent even among regular donors and can hinder both recruitment and retention. This cross-sectional study aimed to estimate the prevalence of these fears in Italian whole-blood and plasma donors, across different levels of donation experience.

Study Design And Methods: A sample of 615 voluntary, unpaid donors from Italy (64.

The association between attitude towards facemasks, quality of donation experience and relationship with healthcare providers: A cross-sectional exploratory study.

Background And Objectives: Facemasks represent an essential measure of prevention against the spread of infectious diseases; however, they lessen the ability to convey and understand emotions through facial expressions. In blood donation settings, facemask wearing could interfere with professionals' tasks, reduce the satisfaction of blood donors and affect their future blood donation behaviour. This preliminary cross-sectional study explored the association of mandatory facemask wearing with the quality of the blood donation process at the end of the coronavirus 2019 (COVID-19) pandemic.

Preventable Predictive Factors of Post-colonoscopy Colorectal Cancer in Inflammatory Bowel Disease.

Background And Aim: Post-colonoscopy colorectal cancer [PCCRC] is a colorectal cancer [CRC] diagnosed after a colonoscopy in which no cancer was detected [index colonoscopy]. Although the overall cumulative rates of PCCRC are low in both the general population and inflammatory bowel disease [IBD] patients, the overall incidence of PCCRC in IBD is greater than that documented in the general population. This study aimed to identify the index colonoscopy-related factors and patients' characteristics influencing IBD-associated PCCRC development.
