PMID: 39107013 DOI: 10.1136/bmjopen-2024-087612

OBJECTIVES: To study nurses' perceptions of patient handoffs in tertiary care hospitals in Kelantan, Malaysia, and to identify predictors of these perceptions.
DESIGN: Cross-sectional study.
SETTING: Three tertiary care hospitals in Kelantan, Malaysia, February-March 2023.
PARTICIPANTS: The study's inclusion criteria were nurses who were Malaysian citizens, working in shifts and possessing a minimum of 6 months of work experience. Nurses holding administrative positions and those unavailable during the study period were excluded from participation. A stratified proportionate random sampling method was employed, and a 100% response rate was achieved, with all 418 selected nurses participating in the study.
OUTCOME MEASURES: Nurses' perceptions of patient handoffs were assessed using the validated Hospital Patient Handoff Questionnaire. Predictors of these perceptions were identified through multiple linear regression analysis.
RESULTS: The study revealed an overall positive perception of handoffs, with a mean score of 3.5 on a 1-5 scale. Receiving formal in-service training on handoff practices (regression coefficient 0.089, 95% CI: 0.016 to 0.161) and expressing satisfaction with the handoff process (regression coefficient 0.330, 95% CI: 0.234 to 0.425) were positively associated with nurses' perceptions. Working in the paediatric department was associated with a lower perception of handoffs (regression coefficient -0.124, 95% CI: -0.195 to -0.053).
CONCLUSIONS: Formal in-service training, satisfaction and working in the paediatric department were significantly associated with nurses' perceptions of patient handoffs in Kelantan. These findings suggest the need for tailored interventions to improve handoff processes and enhance patient safety. Further research could explore the effectiveness of specific training programmes targeting these identified predictors.

Microbial xylanase and pectinase are two extremely valuable enzymes, which have captivated much attention. This can be seen from the increased demand for these enzymes by many industrial sectors. This study investigates the isolation and screening of extracellular xylanopectinolytic enzymes-producing bacteria in a submerged fermentation (SmF). Samples are collected from the compost of empty fruit bunch (EFB) at Biocompost Pilot Plant, located at Biorefinery Plant, Universiti Putra Malaysia. From the experiment, out of 20 isolates, 11 isolates show xylanase or/and pectinase activity, and only one isolate (EFB-11) shows the concurrent activities of xylanase and pectinase. These activities are selected for enzyme production under submerged fermentation (quantitative screening). At the 72nd hour of incubation, xylanase and pectinase show the highest production, which ranges about 42.33 U/mL and 62.17 U/mL (with low amount of cellulase present), supplemented with 2% (w/v) of rice bran as carbon source at incubation temperature level, which is 30°C. Meanwhile, the pH of media is shifted to 8.42, which indicates that EFB-11 isolate is alkalotolerant bacteria and identified as Bacillus subtilis ADI1. This strain proves to have potential in agroindustrial bioconversion and has a promising ability to scale up to an industrial scale.
Fulltext Pulp Enhancement of Oil Palm Empty Fruit Bunches (OPEFBs) via Biobleaching by Using Xylano-Pectinolytic Enzymes of Bacillus amyloliquefaciens ADI2

The present work reports the biobleaching effect on OPEFB pulp upon utilisation of extracellular xylano-pectinolytic enzymes simultaneously yielded from Bacillus amyloliquefaciens ADI2. The impacts of different doses, retention times, pH, and temperatures required for the pulp biobleaching process were delineated accordingly. Here, the OPEFB pulp was subjected to pre-treatment with xylano-pectinolytic enzymes generated from the same alkalo-thermotolerant isolate that yielded those of higher quality. Remarkable enhanced outcomes were observed across varying pulp attributes: for example, enzyme-treated pulp treated to chemical bleaching sequence generated improved brightness of 11.25%. This resulted in 11.25% of less chlorine or chemical consumption required for obtaining pulp with optical attributes identical to those generated via typical chemical bleaching processes. Ultimately, the reduced consumption of chlorine would minimise the organochlorine compounds found in an effluent, resulting in a lowered environmental effect of paper-making processes overall as a consequence. This will undoubtedly facilitate such environmentally-friendly technology incorporation in the paper pulp industry of today.
