Background: Labor analgesic interventions, particularly the use of opioids and epidural anaesthesia, have raised concerns regarding their potential impact on postpartum urinary retention (PUR), necessitating a comprehensive investigation into their association with this clinical outcome.
Methods: This retrospective case-control study analysed clinical data from postpartum patients at our hospital from January 2023 to December 2023. Anaesthetic methods, including opioid and non-opioid drug usage, epidural analgesia and non-use of analgesia, were assessed. Logistic regression analysis was also performed to determine important associations with apparent PUR.
Results: This study included clinical data from 54 postpartum patients with PUR and 54 without urinary retention. A higher percentage of women with apparent PUR received opioids during labour compared with those without PUR ( = 0.033). Conversely, a lower percentage of women with apparent PUR received non-opioid analgesics compared with those without PUR ( = 0.026). In addition, a higher percentage of women with apparent PUR received epidural analgesia compared with those without PUR ( = 0.041). Logistic regression analysis demonstrated that opioid consumption during labour was significantly associated with apparent PUR (odds ratio (OR) = 2.469, = 0.022). By contrast, non-opioid consumption during labour was inversely associated with apparent PUR (OR = 0.297, 95% CI = 0.123-0.681, = 0.005). In addition, the use of epidural analgesia during labour showed a remarkable association with apparent PUR (OR = 2.857, 95% CI = 1.289-6.552, = 0.011).
Conclusions: Opioid use during labour and the use of epidural analgesia were identified as important risk factors for apparent PUR. These findings emphasise the need for a thoughtful and balanced approach to analgesic management during labour to minimise the risk of PUR in obstetric patients.

The Complex Valorization of Black Alder Bark Biomass in Compositions of Rigid Polyurethane Foam.

The use of black alder (BA) bark biomass in rigid polyurethane (PUR) foam compositions was the main task of investigation. Extractive compounds isolated from the bark through hot water extraction were used as precursors for bio-polyol synthesis via acid-free liquefaction with the polyether polyol Lupranol 3300 and through oxypropylation with propylene carbonate. The OH functionality and composition of the polyols were analyzed via wet chemistry and FTIR spectroscopy.

The aim of this work was to synthesize polyurethane foams based on petrochemical polyols and biopolyols with specific apparent densities (40, 60, 80, 100, and 120 kg/m), test their properties, glycolyze them, and finally analyze each glycolyzed product. The petroleum-based foams, used as reference foams, and the bio-based foams underwent a series of standard tests to define their properties (the content of closed cells 20-95%, compressive strength 73-1323 kPa, thermal conductivity 24-42 mW/m∙K, brittleness 4.6-82.

Amidst depleting water resources, rising crop water needs, changing climates, and soil fertility decline from inorganic modifications of soil, the need for sustainable agricultural solutions has been more pressing. The experimental work aimed to inspect the potential of organically activated biochar in improving soil physicochemical and nutrient status as well as improving biochemical and physiological processes, and optimizing yield-related attributes under optimal and deficit irrigation conditions. Biochar enhances soil structure, water retention, and nutrient availability, while improving plant nutrient uptake and drought resilience.

The automotive industry uses polyurethane (PUR) foam core in the vehicle headliner composite. The sector demands recycling suggestions to reduce its scrap and decrease the expenses. This work investigated the PUR depolymerization using synthesized 2-hydroxypropyl ricinoleate (2-HPR) from castor oil and incorporated the liquid recyclate (REC) into the original PUR foam.
