Is acupuncture safe in the ICU? A systematic review and meta-analysis

Background and purposeThe safety of interventions for critically ill patients is a crucial issue. In recent years, several studies have treated critically ill patients with acupuncture. However, the safety of acupuncture in this setting remains to be systematically measured.MethodsIn May 2022, the electronic databases of PubMed and the Cochrane Library were searched for studies comparing acupuncture interventions to control interventions in critically ill patients. Study outcomes examined the incidence of severe adverse events (AEs), minor AEs, adverse reactions, ICU stays, and 28-day mortality.ResultsA total of 31 articles were analyzed, and no serious AEs related to acupuncture treatment were identified. No significant differences were found between the groups in the meta-analysis of minor AEs (risk ratio [RR] 5.69 [0.34, 96.60], P = 0.23, I2 = 76%). A reduced risk in the incidence of adverse reactions following acupuncture intervention was evidenced (RR 0.33 [0.22, 0.50], P = 0.00001, I2 = 44%). The patients in the acupuncture arm spent significantly less time in the intensive care unit (ICU) (Mean difference −1.45 [−11.94, −10.97], P = 0.00001, I2 = 56%) and also exhibited lower 28-day mortality rates (odds ratio 0.61 [0.48, 0.78], P = 0.0001, I2 = 0%).ConclusionThere is no evidence to indicate a higher risk of severe or minor AEs in patients who receive acupuncture. Acupuncture demonstrated favorable results in both ICU stay and 28-day mortality measurements, in addition to presenting with fewer adverse reactions compared to routine ICU care. However, the low certainty of the evidence resulting from a high risk of bias in the included studies merits substantial consideration, and further research is still warranted.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=142131, identifier: CRD42020142131

A green functionalized method of Cu-BTC on poly(vinyl alcohol)/chitosan composite mat and its antibacterial potential

Recent outbreaks of infectious diseases have stimulated considerable interest with reports that millions of people are at risk of disease in different forms worldwide. Therefore, Cu-based framework functionalized nanofibers, were developed as modern antibacterial hybrid materials to produce outstanding synergistic properties derived from each composition. Cu-BTC, a well-known Cu-based framework, is proposed to provide antibacterial properties with lower cytotoxicity and prolonged durability. Chitosan/polyvinyl alcohol nanofibers were electrospun with increased diameter size by boosting chitosan concentrations within a range from 80 to 570 nanometers (nm). Cu-BTC nanopowders were synthesized by a simple sonochemical method and FTIR results indicated formation of frameworks from the Cu-O coordinated bond. Cu-BTC was functionalized onto chitosan/polyvinyl alcohol nanofibers by direct and self-assembly approaches. Results of SEM and EDX were that the direct method exhibited better Cu-BTC functionalization on fiber surface and provided good dispersion and uniform coverage of Cu-BTC particles with high Cu concentration content of 1.20% wt. Antibacterial test was quantified using the clear zone of inhibition (AATCC-147). The values exhibited the no bacterial growth against Staphylococcus aureus and Escherichia coli at 2.01±0.02 and 1.99±0.05 mm, respectively. Cu-BTC functionalized chitosan/poly vinyl alcohol hybrid nanofibers could improve antibacterial properties compared to neat composite mats, but limitation of their features might be inadequate for encouraging water uptake hydrated from body cells, resulting in lower than estimated performance

Design and Development of Innovative Steam Injection for High-Temperature Short-Time Liquid Foods

Jet impingement has been effective in reducing the process time and improvement of product quality in various industrial applications, such as textile and paper drying, electronic cooling, glass quenching and food processing. The current work applied innovative steam injection to liquid food continuous sterilization. The multiple impingement jets of steam and product came together in the impingement tank. The effects were investigated on the Reynolds number, steam temperature and jet-to-target spacing (H/d), sterilization temperature and heat transfer efficiency in water and pineapple juice tests. The Reynolds number was based on the nozzle configuration and liquid flow rate. The study investigated product injection plates formed using two, three or four circular holes (diameter 2 mm), steam injection plates with six, nine or twenty circular holes (diameter 1 mm), steam temperatures of 120, 125 or 130 °C and H/d values of 1, 3, 5 or 7. The different options were tested with water to determine the optimal conditions, and then tested with pineapple juice. The results showed that the optimal conditions from water testing that provided the highest heat transfer efficiency occurred with two jet nozzles, six steam injection plates, a steam temperature of 120 °C and an H/d value of 1.</jats:p

Green Dyeing and Antibacterial Treatment of Hemp Fabrics Using Punica granatum Peel Extracts

In this study, the dyeing performance and antibacterial properties of pomegranate (Punica granatum) peel extracts were investigated, when applied to hemp fabric. A tannin-rich natural dye was extracted using water at 100°C. As the antibacterial agent was sensitive to temperature, it was extracted using Soxhlet apparatus with methanol at 55°C. The color strength (K/S) values were investigated and found to increase in line with the dye concentration, dyeing time, and temperature. Optimal dyeing of the hemp fabric was achieved when applying 6% w/v of extract at 80°C for 60 min. This produced a yellowish-brown appearance. The dyed fabrics were rated as good to excellent for color fastness against washing, water, sea water, and perspiration. The dyed fabrics were next finished with the antibacterial agent extracted from the peel and tested for activity against Staphylococcus aureus (Gram positive) and Klebsiella pneumoniae (Gram negative), using the AATCC-100 (percentage reduction) test. The fabric was demonstrated to be 99.99% effective against Staphylococcus aureus, and this was conserved across 20 wash cycles
