Interprofessional team-based learning ::a qualitative study on the experiences of nursing and physiotherapy students
Traditional discipline-specific training has limitations in facilitating inter-professional
communication and collaboration. To address this issue, two local universities in
Hong Kong launched an interprofessional team-based learning program to allow the
undergraduate healthcare students to formteams and experience collaborative problemsolving.
This study aimed to evaluate the experiences of nursing and physiotherapy
undergraduates following interprofessional learning activities. Twenty-seven 3rd-year
nursing and physiotherapy undergraduates were recruited through purposive sampling.
Semi-structured interviews were conducted, and written feedback was solicited until
data saturation was achieved. An inductive thematic analysis was used for the data, and
each theme was mutually exclusive. The findings revealed the positive experiences of
the students with this interprofessional learning activity. Three main themes emerged:
(1) the process of interprofessional learning; (2) profession-related outcomes of
interprofessional learning; and (3) patient-related outcomes of interprofessional learning.
The study indicated that interprofessional team-based learning activities enhanced
learning experiences of the students through interactive learning with other healthcare
students. Experiences of relationships that are trustful and complementary allow students
to develop confidence in knowledge transfer and in interprofessional collaboration, as
well as in providing a holistic patient-centered care. These findings substantiate the
importance and value of interprofessional learning in healthcare education
Hematopoietic Transcription Factor RUNX1 is Essential for Promoting MacrophageâMyofibroblast Transition in NonâSmallâCell Lung Carcinoma
Abstract Macrophageâmyofibroblast transition (MMT) is a newly discovered pathway for mass production of proâtumoral cancerâassociated fibroblasts (CAFs) in nonâsmall cell lung carcinoma (NSCLC) in a TGFâÎČ1/Smad3 dependent manner. Better understanding its regulatory signaling in tumor microenvironment (TME) may identify druggable target for the development of precision medicine. Here, by dissecting the transcriptome dynamics of tumorâassociated macrophage at singleâcell resolution, a crucial role of a hematopoietic transcription factor Runx1 in MMT formation is revealed. Surprisingly, integrative bioinformatic analysis uncovers Runx1 as a key regulator in the downstream of MMTâspecific TGFâÎČ1/Smad3 signaling. Stromal Runx1 level positively correlates with the MMTâderived CAF abundance and mortality in NSCLC patients. Mechanistically, macrophageâspecific Runx1 promotes the transcription of genes related to CAF signatures in MMT cells at genomic level. Importantly, macrophageâspecific genetic deletion and systemic pharmacological inhibition of TGFâÎČ1/Smad3/Runx1 signaling effectively prevent MMTâdriven CAF and tumor formation in vitro and in vivo, representing a potential therapeutic target for clinical NSCLC
Comparison of clinical outcome and ease of handling in two double-bag systems in continuous ambulatory peritoneal dialysis: A prospective, randomized, controlled, multicenter study
Background: We performed a prospective, randomized, controlled, multicenter study on the use of two double-bag disconnect systems: Stay-Safe (SS; Fresenius Deutschland GmbH2) and Ultrabag (UB; Baxter Healthcare, Deerfield, IL) to assess the ease of handling, peritonitis rate, exit-site infection rate, and clinical outcome. Methods: We enrolled 110 new continuous ambulatory peritoneal dialysis (CAPD) patients; 55 patients were randomized to SS treatment, and 55 patients, to UB treatment. Results: Patients using the UB and SS systems were followed up for 946 and 846 patient-months, respectively. There were 21 episodes of peritonitis in 18 patients in the UB group and 23 episodes in 18 patients in the SS group. No significant difference was observed in peritonitis rates between the two systems, which were 45 and 36.8 patient-months per episode for the UB and SS groups, respectively. At 12 months, 82.1% of patients in the UB group and 72.1% in the SS group were free of peritonitis; at 18 months, 71.1% and 62.2% were free of peritonitis for the UB and SS groups, respectively (P = 0.559). Gram-positive organisms accounted for 28.6% of infections in the UB group and 39.1% in the SS group. Exit-site infection rates were one episode per 21 patient-months versus 19.2 patient-months in the UB and SS groups, respectively (P = 0.743). Patients perceived SS as easier to handle in 4 of the 13 steps immediately post-CAPD training. However, there was no significant difference in rankings between the two systems after 1 month of adaptation. Median training periods were 4 and 5 days for the SS and UB groups, respectively (P = 0.640). Conclusion: The two double-bag systems (UB and SS) have similar incidences of peritonitis and exit-site infection. Both systems showed comparably good clinical outcome. The SS system is easier to learn during the initial training period, but the difference is not significant after 1 month's adaptation. © 2002 by the National Kidney Foundation, Inc.Link_to_subscribed_fulltex
Probable Airborne Transmission of Burkholderia pseudomallei Causing an Urban Outbreak of Melioidosis during Typhoon Season in Hong Kong, China. <subtitle>Urban Outbreak of Melioidosis in Hong Kong</subtitle>
ABSTRACTBetween January 2015 and October 2022, 38 patients with culture-confirmed melioidosis were identified in the Kowloon West (KW) Region, Hong Kong. Notably, thirty of them were clustered in the Sham Shui Po (SSP) district, which covers an estimated area of 2.5 km2. Between August and October 2022, 18 patients were identified in this district after heavy rainfall and typhoons. The sudden upsurge in cases prompted an environmental investigation, which involved collecting 20 air samples and 72 soil samples from residential areas near the patients. A viable isolate of Burkholderia pseudomallei was obtained from an air sample collected at a building site five days after a typhoon. B. pseudomallei DNA was also detected in 21 soil samples collected from the building site and adjacent gardening areas using full-length 16S rRNA gene sequencing, suggesting that B. psuedomallei is widely distributed in the soil environment surrounding the district. Core genome-multilocus sequence typing showed that the air sample isolate was phylogenetically clustered with the outbreak isolates in KW Region. Multispectral satellite imagery revealed a continuous reduction in vegetation region in SSP district by 162,255 m2 from 2016 to 2022, supporting the hypothesis of inhalation of aerosols from the contaminated soil as the transmission route of melioidosis during extreme weather events. This is because the bacteria in unvegetated soil are more easily spread by winds. In consistent with inhalational melioidosis, 24 (63.2%) patients had pneumonia. Clinicians should be aware of melioidosis during typhoon season and initiate appropriate investigation and treatment for patients with compatible symptoms
Table_2_The clinical utility of Nanopore 16S rRNA gene sequencing for direct bacterial identification in normally sterile body fluids.xlsx
The prolonged incubation period of traditional culture methods leads to a delay in diagnosing invasive infections. Nanopore 16S rRNA gene sequencing (Nanopore 16S) offers a potential rapid diagnostic approach for directly identifying bacteria in infected body fluids. To evaluate the clinical utility of Nanopore 16S, we conducted a study involving the collection and sequencing of 128 monomicrobial samples, 65 polymicrobial samples, and 20 culture-negative body fluids. To minimize classification bias, taxonomic classification was performed using 3 analysis pipelines: Epi2me, Emu, and NanoCLUST. The result was compared to the culture references. The limit of detection of Nanopore 16S was also determined using simulated bacteremic blood samples. Among the three classifiers, Emu demonstrated the highest concordance with the culture results. It correctly identified the taxon of 125 (97.7%) of the 128 monomicrobial samples, compared to 109 (85.2%) for Epi2me and 102 (79.7%) for NanoCLUST. For the 230 cultured species in the 65 polymicrobial samples, Emu correctly identified 188 (81.7%) cultured species, compared to 174 (75.7%) for Epi2me and 125 (54.3%) for NanoCLUST. Through ROC analysis on the monomicrobial samples, we determined a threshold of relative abundance at 0.058 for distinguishing potential pathogens from background in Nanopore 16S. Applying this threshold resulted in the identification of 107 (83.6%), 117 (91.4%), and 114 (91.2%) correctly detected samples for Epi2me, Emu, and NanoCLUST, respectively, in the monomicrobial samples. Nanopore 16S coupled with Epi2me could provide preliminary results within 6 h. However, the ROC analysis of polymicrobial samples exhibited a random-like performance, making it difficult to establish a threshold. The overall limit of detection for Nanopore 16S was found to be about 90 CFU/ml.</p
