Cell-type specific molecular expression levels by restricted-dimensional cytometry.

BACKGROUND: Cytometric analysis has been commonly used to delineate distinct cell subpopulations among peripheral blood mononuclear cells by the differential expression of surface receptors. This capability has reached its apogee with high-dimensional approaches such as mass cytometry and spectral cytometry that include simultaneous assessment of 20-50 analytes. Unfortunately, this approach also engenders significant complexity with analytical and interpretational pitfalls. METHODS: Here, we demonstrate a complementary approach with restricted-dimensionality to assess cell-type specific intracellular molecular expression levels at exceptional levels of precision. The expression of five analytes was individually assessed in four mononuclear cell-types from peripheral blood. RESULTS: Distinctions in expression levels were seen between cell-types and between samples from different donor groups. Mononuclear cell-type specific molecular expression levels distinguished pregnant from nonpregnant women and G-CSF-treated from untreated persons. Additionally, the precision of our analysis was sufficient to quantify a novel relationship between two molecules-Rel A and translocator protein-by correlational analysis. CONCLUSIONS: Restricted-dimensional cytometry can provide a complementary approach to define characteristics of cell-type specific intracellular protein and phosphoantigen expression in mononuclear cells.

The Physical Abilities and Mobility Scale as a New Measure of Functional Progress in the PICU.

Assessing functional motor changes and their relationship to discharge needs in the pediatric intensive care unit (PICU) population is difficult given challenges quantifying small functional gains with current tools. Therefore, we compared the Physical Abilities and Mobility Scale (PAMS) to the Functional Status Scale (FSS) in PICU patients to assess correlation and differences and association with discharge needs. This study was a retrospective chart review of all patients (2-18 years old) admitted to the PICU and cardiac PICU for over 9 months who received early mobility services, including PAMS and FSS scoring. Correlation between scales, relationship of scores to disposition, and logistic regression model of changes in PAMS in relation to disposition were determined. Data were obtained for 122 patients. PAMS and FSS scores strongly negatively correlated (Spearman's ρ = - 0.85), but with a nonlinear relationship, as the PAMS more readily differentiated among patients with higher functional status. The median FSS at discharge was 12.5 for those recommended an inpatient rehabilitation facility (IRF) ( n = 24), versus 9 for those recommended discharge home ( n = 83, Δ 3.5, 95% confidence interval [CI]: 1-6, around one-tenth of FSS scale). The corresponding median PAMS were 42 and 66 (Δ 24, 95% CI: 10-30, one-fourth of PAMS scale). Although not statistically significant, a logistic regression model was consistent with patients who showed modest change in PAMS across hospitalization but persistent deficits (PAMS < 60) were more likely to be recommended an IRF. The PAMS correlates to the FSS, but appears more sensitive to small functional changes, especially in higher functioning patients. It may be useful in prognosticating discharge needs.

Minute virus of mice shows oncolytic activity against pancreatic cancer cells exhibiting a mesenchymal phenotype.

Pancreatic cancer will soon become the second cause of death by cancer in Western countries. The main barrier to increase the survival of patients with this disease requires the development of novel and efficient therapeutic strategies that better consider tumor biology. In this context, oncolytic viruses emerge as promising therapeutics. Among them, the fibrotropic minute virus of mice prototype (MVMp) preferentially infects migrating and undifferentiated cells that highly resemble poorly differentiated, basal-like pancreatic tumors showing the worst clinical outcome. We report here that MVMp specifically infects, replicates in, and kills pancreatic cancer cells from murine and human origin with a mesenchymal, basal-like profile, while sparing cancer cells with an epithelial phenotype. Remarkably, MVMp infection, at a dose that does not provoke tumor growth inhibition in athymic mice, shows significant antitumoral effect in immune-competent models; extended mouse survival; and promoted the massive infiltration of tumors by innate, myeloid, and cytotoxic T cells that exhibit a less terminally exhausted phenotype. Collectively, we demonstrate herein for the first time that MVMp is specific and oncolytic for pancreatic tumors with mesenchymal, basal-like profile, paving the way for precision-medicine opportunities for the management of the most aggressive and lethal form of this disease.

Comparison of two autologous hematopoietic stem cell mobilization strategies in patients with multiple myeloma: CE plus G-CSF versus G-CSF only: A single-center retrospective analysis.

BACKGROUND: Despite recent advances in the treatment of multiple myeloma, high-dose chemotherapy followed by autologous hematopoietic stem cell transplantation (ASCT) remains an essential therapeutic keystone. As for the stem cell mobilization procedure, different regimens have been established, usually consisting of a cycle of chemotherapy followed by application of granulocyte-colony stimulating factor (G-CSF), although febrile neutropenia is a common complication. Following national guidelines, our institution decided to primarily use G-CSF only mobilization during the COVID-19 pandemic to minimize the patients' risk of infection and to reduce the burden on the health system. STUDY DESIGN AND METHODS: In this retrospective single-center analysis, the efficacy and safety of G-CSF only mobilization was evaluated and compared to a historic control cohort undergoing chemotherapy-based mobilization by cyclophosphamide and etoposide (CE) plus G-CSF. RESULTS: Although G-CSF only was associated with a higher need for plerixafor administration (p < .0001) and a higher number of apheresis sessions per patient (p = .0002), we were able to collect the target dose of hematopoietic stem cells in the majority of our patients. CE mobilization achieved higher hematopoietic stem cell yields (p = .0015) and shorter apheresis sessions (p < .0001) yet was accompanied by an increased risk of febrile neutropenia (p < .0001). There was no difference in engraftment after ASCT. DISCUSSION: G-CSF only mobilization is a useful option in selected patients with comorbidities and an increased risk of serious infections, especially in the wintertime or in future pandemics.

Seasonal patterns of nonstructural carbohydrate storage and mobilization in two tree species with distinct life-history traits.

Nonstructural carbohydrates (NSC) are essential for tree growth and adaptation, yet our understanding of the seasonal storage and mobilization dynamics of whole-tree NSC is still limited, especially when tree functional types are involved. Here, Quercus acutissima Carruth. and Pinus massoniana Lamb. with distinct life-history traits (i.e., a deciduous broadleaf species vs. an evergreen coniferous species) were studied to assess the size and seasonal fluctuations of organ and whole-tree NSC pools with a focus on comparing differences in carbon resource mobilization patterns between the two species. We sampled the organs (leaf, branch, stem, and root) of the target trees repeatedly over four seasons of the year. Then, NSC concentrations in each organ were paired with biomass estimates from the allometric model to generate whole-tree NSC pools. The seasonal dynamics of the whole-tree NSC of Q. acutissima and P. massoniana reached the peak in autumn and summer, respectively. The starch pools of the two species were supplemented in the growing season while the soluble sugar pools were the largest in the dormant season. Seasonal dynamics of organ-level NSC concentrations and pools were affected by organ type and tree species, with above-ground organs generally increasing during the growing season and P. massoniana roots decreasing during the growing season. In addition, the whole-tree NSC pools of P. massoniana were larger but Q. acutissima showed larger seasonal fluctuations, indicating that larger storage was not associated with more pronounced seasonal fluctuations. We also found that the branch and root were the most dynamic organs of Q. acutissima and P. massoniana, respectively, and were the major suppliers of NSC to support tree growth activities. These results provide fundamental insights into the dynamics and mobilization patterns of NSC at the whole-tree level, and have important implications for investigating environmental adaptions of different tree functional types.

Fatigue, fear of being mobilized and residual limb pain limit independent basic mobility and physiotherapy for patients early after major dysvascular lower extremity amputation: A prospective cohort study.

AIM: Early mobilization of patients with a major lower extremity amputation (LEA) is often a challenge because of lack of compliance. Therefore, we investigated factors limiting independent mobility and physiotherapy on the first day with physiotherapy (PTDay1) and the following 2 days after LEA. METHODS: A total of 60 consecutive patients, mean age 73.7 years (SD 12.1 years), undergoing LEA were included over a period of 7 months. The Basic Amputee Mobility Score was used to assess basic mobility. Predefined limitations for not achieving independent mobility or not completing physiotherapy were residual limb pain, pain elsewhere, fear of being mobilized, fatigue, nausea/vomiting, acute cognitive dysfunction or "other" factors reported on PTDay1 and the following 2 days after LEA. RESULTS: Fatigue and fear of being mobilized were the most frequent limitations for not achieving independent mobility on PTDay1 and the following 2 days after LEA. Patients (n = 55) who were not independent in the Basic Amputee Mobility Score activity transferring from bed to chair on PTDay1 were limited by fatigue (44%) and fear of being mobilized (33%). A total of 21 patients did not complete planned physiotherapy on PTDay1, and were limited by fatigue (38%), residual limb pain (24%) and "other" factors (24%). CONCLUSION: Fatigue and fear of being mobilized were the most frequent factors that limited independent mobility early after LEA. Fatigue, residual limb pain and "other" factors limited completion of physiotherapy. Geriatr Gerontol Int 2024; ••: ••-••.

Effects of robotic-assisted early mobilization versus conventional mobilization in intensive care unit patients: prospective interventional cohort study with retrospective control group analysis.

BACKGROUND: Approximately one in three survivors of critical illness suffers from intensive-care-unit-acquired weakness, which increases mortality and impairs quality of life. By counteracting immobilization, a known risk factor, active mobilization may mitigate its negative effects on patients. In this single-center trial, the effect of robotic-assisted early mobilization in the intensive care unit (ICU) on patients' outcomes was investigated. METHODS: We enrolled 16 adults scheduled for lung transplantation to receive 20 min of robotic-assisted mobilization and verticalization twice daily during their first week in the ICU (intervention group: IG). A control group (CG) of 13 conventionally mobilized patients after lung transplantation was recruited retrospectively. Outcome measures included the duration of mechanical ventilation, length of ICU stay, muscle parameters evaluated by ultrasound, and quality of life after three months. RESULTS: During the first week in the ICU, the intervention group received a median of 6 (interquartile range 3-8) robotic-assisted sessions of early mobilization and verticalization. There were no statistically significant differences in the duration of mechanical ventilation (IG: median 126 vs. CG: 78 h), length of ICU stay, muscle parameters evaluated by ultrasound, and quality of life after three months between the IG and CG. CONCLUSION: In this study, robotic-assisted mobilization was successfully implemented in the ICU setting. No significant differences in patients' outcomes were observed between conventional and robotic-assisted mobilization. However, randomized and larger studies are necessary to validate the adequacy of robotic mobilization in other cohorts. TRIAL REGISTRATION: This single-center interventional trial was registered in clinicaltrials.gov as NCT05071248 on 27/08/2021.

A comparative review of Aphexda and Mozobil for mobilization prior to stem cell collection.

High-dose chemotherapy followed by autologous hematopoietic stem cell transplantation is the standard of care for eligible patients with newly diagnosed multiple myeloma leading to prolonged progression free and overall survival. Successful engraftment following hematopoietic stem cell infusion requires adequate stem cell doses. Current mobilization regimens include granulocyte colony-stimulating factor (G-CSF) with or without plerixafor. Motixafortide is a recently approved agent that can be used in combination with G-CSF for mobilization. In the absence of any head-to-head trials comparing the two products, this article aims to outline the similarities and differences of these two agents. Though moxitafortide has a more favorable pharmacokinetic profile in comparison to plerixafor, in clinical trials, the agents demonstrated similar efficacy. In addition, the use of motixafortide in clinical practice may be limited by product cost as well as administration and monitoring requirements.

Status quo and influencing factors of multiprofessional and multidisciplinary teamwork for early mobilization in mechanically ventilated patients in ICUs: A multi-centre survey study.

AIM: To understand the status quo of multiprofessional and multidisciplinary collaboration for early mobilization of mechanically ventilated patients in Chinese ICUs and identify any factors that may influence this practice. DESIGN: A multi-centre cross-sectional survey. METHODS: From October to November 2022, the convenience sampling method was used to select ICU multiprofessional and multidisciplinary early mobility members (including physicians, nurses and physiotherapists) from 27 tertiary general hospitals in 14 provinces, cities and autonomous regions of China. They were asked to complete an author-developed questionnaire on the status of collaboration and the Assessment of Inter-professional Team Collaboration Scale. A multiple linear regression model was used to analyse the factors associated with the level of collaboration. RESULTS: Physicians, nurses and physiotherapists mostly suffered from the lack of normative protocols, unclear division of responsibilities and unclear multiprofessional and multidisciplinary teams when using a collaborative approach to early activities. Multiple linear regression analysis showed that the number of ICU patients managed, the existence of norms and processes, the attitude of colleagues around them, the establishment of a team, communication methods and activity leaders were significant influences on the level of collaboration among members of the multiprofessional and multidisciplinary early activities. CONCLUSION: The collaboration of multiprofessional and multidisciplinary early activity members for mechanically ventilated patients in the ICU remains unclear, and the collaboration strategy needs to be constructed and improved, taking into account China's human resources and each region's economic development level. IMPACT: This study investigates the collaboration status of multiprofessional and multidisciplinary activity members from the perspective of teamwork, analyses the reasons affecting the level of collaboration and helps to develop better teamwork strategies to facilitate the implementation of early activities. PATIENT OR PUBLIC CONTRIBUTION: The participants in this study were multiprofessional and multidisciplinary medical staff who performed early activities for ICU patients.

Effect of nanobubbles on the mobilization of microplastics in shorelines subject to seawater infiltration.

The widespread presence of microplastics (MPs) in the ocean has varying degrees of impact on ecosystems and even human health. Coastal tidal zones are crucial in controlling the movement of MPs, which are influenced by waves and tidal forces. Meanwhile, natural nanobubbles (NBs) in the ocean can affect the hydrodynamic properties of the tidal zone. The mobilization of MPs in coastal tidal zones under the effect of NBs has been less studied. In this study, we explored natural NBs' influence on the mobilization of MPs in shorelines subject to seawater infiltration. Using glass beads as a substrate, a coastal porous environment was constructed through column experiments, and the pump-controlled water flow was used to study the transport of MPs subject to seawater movement within the substrate. The infiltration of MPs under continuous and transient conditions, as well as the upward transport induced by flood tide, were considered. The role of salinity in the interactions between NBs, MPs, and substrates was evaluated. Salinity altered the energy barriers between particles, which in turn affected the movement of MPs within the substrate. In addition, hydrophilic MPs were more likely to infiltrate within the substrate and had different movement patterns under continuous and transient flow conditions. The motion of the MPs within the substrate varied with flow rate, and NBs limited the vertical movement of MPs in the tidal zone. It was also observed that NBs adsorbed readily onto substrates, altering the surface properties of substrates, particularly their ability to attach and detach from other substances.

A comprehensive evaluation of 80 consecutive robotic low anterior resections: impact of not mobilizing the splenic flexure alongside low-tie vascular ligation as a standardized technique.

Rectal cancer surgery represents challenges due to its location. To overcome them and minimize the risk of anastomosis-related complications, some technical maneuvers or even a diverting ileostomy may be required. One of these technical steps is the mobilization of the splenic flexure (SFM), especially in medium/low rectal cancer. High-tie vascular ligation may be another one. However, the need of these maneuvers may be controversial, as especially SFM may be time-consuming and increase the risk of iatrogenic. The objective is to present the short- and long-term outcomes of a low-tie ligation combined with no SFM in robotic low anterior resection (LAR) for mid- and low rectal cancer as a standardized technique. A retrospective observational single-cohort study was carried out at Reina Sofia University Hospital, Cordoba, Spain. 221 robotic rectal resections between Jul-18th-2018 and Jan-12th-2023 were initially considered. After case selection, 80 consecutive robotic LAR performed by a single surgeon were included. STROBE checklist assessed the methodological quality. Histopathological, morbidity and oncological outcomes were assessed. Anastomotic stricture occurrence and distance to anal verge were evaluated after LAR by rectosigmoidoscopy. Variables related to the ileostomy closure such as time to closure, post-operative complications or hospital stay were also considered. The majority of patients (81.2%) presented a mid-rectal cancer and the rest, lower location (18.8%). All patients had adequate perfusion of the anastomotic stump assessed by indocyanine green. Complete total mesorectal excision was performed in 98.8% of the patients with a lymph node ratio < 0.2 in 91.3%. The anastomotic leakage rate was 5%. One patient (1.5%) presented local recurrence. Anastomosis stricture occurred in 7.5% of the patients. The limitations were small cohort and retrospective design. The non-mobilization of the splenic flexure with a low-tie ligation in robotic LAR is a feasible and safe procedure that does not affect oncological outcomes.

Mobilizing community-driven health promotion through community granting programs: a rapid systematic review.

BACKGROUND: Effective health promotion responds to the unique needs of communities. Community granting programs that fund community-driven health promotion initiatives are a potential mechanism to meet those unique needs. While numerous community health-focused programs are available, the various strategies used by granting programs to foster engagement, administer grants and support awardees have not been systematically evaluated. This rapid systematic review explores the administration of community granting programs and how various program components impact process and population health outcomes. METHODS: A systematic search was conducted across three databases: Medline, SocINDEX, and Political Science Database. Single reviewers completed screening, consistent with a rapid review protocol. Studies describing or evaluating community granting programs for health or public health initiatives were included. Data regarding program characteristics were extracted and studies were evaluated for quality. A convergent integrated approach was used to analyze quantitative and qualitative findings. RESULTS: Thirty-five community granting programs, described in 36 studies, were included. Most were descriptive reports or qualitative studies conducted in the USA. Program support for grant awardees included technical assistance, workshops and training, program websites, and networking facilitation. While most programs reported on process outcomes, few reported on community or health outcomes; such outcomes were positive when reported. Programs reported that many funded projects were likely sustainable beyond program funding, due to the development of awardee skills, new partnerships, and securing additional funding. From the perspectives of program staff and awardees, facilitators included the technical assistance and workshops provided by the programs, networking amongst awardees, and the involvement of community members. Barriers included short timelines to develop proposals and allocate funds. CONCLUSIONS: This review provides a comprehensive overview of health-related community granting programs. Grant awardees benefit from technical assistance, workshops, and networking with other awardees. Project sustainability is enhanced by the development of new community partnerships and grant-writing training for awardees. Community granting programs can be a valuable strategy to drive community health, with several key elements that enhance community mobilization. REGISTRATION: PROSPERO #CRD42023399364.

Effects of scapular treatment on chronic neck pain: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Chronic neck pain (CNP) is a common public health problem that affects daily living activities and quality of life. There is biomechanical interdependence between the neck and scapula. Studies have shown that shoulder blade function might be related to chronic neck pain. We therefore evaluated the effects of scapular targeted therapy on neck pain and function in patients with CNP. METHODS: Databases, including MEDLINE (via PubMed), EMBASE (via Ovid), Ovid, Web of Science, and Scopus, were systematically searched for randomized controlled trials published in English investigating treatment of the scapula for CNP before July 16, 2023. RESULTS: A total of 313 participants were included from 8 RCTs. Compared with those in the control group, the intervention in the scapular treatment group exhibited greater improvement in pain intensity (standardized mean difference (SMD) = 2.55; 95% CI = 0.97 to 4.13; P = 0.002), with moderate evidence. Subgroup analysis for pain intensity revealed a significant difference between the sexes, with only the female population (SMD = 6.23, 95% CI = 4.80 to 7.65) showing better outcomes than those with both sexes (SMD = 1.07, 95% CI = 0.57 to 1.56) (p < 0.00001). However, moderate evidence demonstrated no improvement in neck disability after scapular treatment (SMD of 0.24[-0.14, 0.62] of Neck Disability Index or Northwick Park Neck Pain Questionnaire). No effect of scapular treatment was shown on the pressure pain threshold (PPT). The cervical range of motion (CROM) and electromyographic activity of neck muscles could not be conclusively evaluated due to limited support in the articles, and further study was needed. However, the patient's head forward posture appeared to be corrected after scapular treatment. CONCLUSION: Scapular therapy was beneficial for relieving pain intensity in patients with CNP, especially in women. Head forward posture might also be corrected with scapular therapy. However, scapular therapy may have no effect on the PPT or neck disability. However, whether scapular therapy could improve CROM and cervical muscle activation in patients with CNPs had not been determined and needed further study.

Strategies to implement evidence-informed decision making at the organizational level: a rapid systematic review.

BACKGROUND: Achievement of evidence-informed decision making (EIDM) requires the integration of evidence into all practice decisions by identifying and synthesizing evidence, then developing and executing plans to implement and evaluate changes to practice. This rapid systematic review synthesizes evidence for strategies for the implementation of EIDM across organizations, mapping facilitators and barriers to the COM-B (capability, opportunity, motivation, behaviour) model for behaviour change. The review was conducted to support leadership at organizations delivering public health services (health promotion, communicable disease prevention) to drive change toward evidence-informed public health. METHODS: A systematic search was conducted in multiple databases and by reviewing publications of key authors. Articles that describe interventions to drive EIDM within teams, departments, or organizations were eligible for inclusion. For each included article, quality was assessed, and details of the intervention, setting, outcomes, facilitators and barriers were extracted. A convergent integrated approach was undertaken to analyze both quantitative and qualitative findings. RESULTS: Thirty-seven articles are included. Studies were conducted in primary care, public health, social services, and occupational health settings. Strategies to implement EIDM included the establishment of Knowledge Broker-type roles, building the EIDM capacity of staff, and research or academic partnerships. Facilitators and barriers align with the COM-B model for behaviour change. Facilitators for capability include the development of staff knowledge and skill, establishing specialized roles, and knowledge sharing across the organization, though staff turnover and subsequent knowledge loss was a barrier to capability. For opportunity, facilitators include the development of processes or mechanisms to support new practices, forums for learning and skill development, and protected time, and barriers include competing priorities. Facilitators identified for motivation include supportive organizational culture, expectations for new practices to occur, recognition and positive reinforcement, and strong leadership support. Barriers include negative attitudes toward new practices, and lack of understanding and support from management. CONCLUSION: This review provides a comprehensive analysis of facilitators and barriers for the implementation of EIDM in organizations for public health, mapped to the COM-B model for behaviour change. The existing literature for strategies to support EIDM in public health illustrates several facilitators and barriers linked to realizing EIDM. Knowledge of these factors will help senior leadership develop and implement EIDM strategies tailored to their organization, leading to increased likelihood of implementation success.

Increased Serum Levels of N-terminal pro-B-type Natriuretic Peptide (NT-proBNP) in Mobilized Healthy Donors with G-CSF: A Cohort Study.

Limited data regarding elevation of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in mobilized donors with G-CSF is available. We extended these findings by examining serum NT-proBNP in a cohort study including 35 healthy donors and 69 patients who received G-CSF for CD34+ mobilization as well as 54 patients who did not receive G-CSF but who underwent collection of CD3+ cells for chimeric antigen receptor (CAR) T-cell manufacturing. No donor in the three cohorts experienced significant cardiac adverse events. NT-proBNP levels were measured before and after G-CSF administration and after finishing apheresis procedure. NT-proBNP increase was observed in mobilized healthy donors after G-CSF administration, but was not observed in mobilized or non-mobilized patients. Only in the cohort of healthy donors, pairwise comparisons using Wilcoxon signed ranks test showed a significant increase between the mean serum NT-proBNP level after G-CSF administration and the mean serum NT-proBNP level measured before G-CSF administration (231.09 ± 156.15 pg/mL vs. 58.88 ± 26.84 pg/mL; P < .01). No correlation was observed between NT-proBNP increase and G-CSF dose (rs = 0.09; n = 32; P = .6) and no other variables contributing to predict serum NT-proBNP increase were detected. In conclusion, we observed a statistically, although not clinically, significant increase of NT-proBNP in healthy donors who received G-CSF as CD34+ cell mobilization.

Impact of the End PJ Paralysis interventions on patient health outcomes at the participating hospitals in Alberta, Canada.

PURPOSE: Multiple hospitals in Alberta implemented the End PJ Paralysis - a multicomponent inpatient ambulation initiative aimed at preventing the adverse physical and psychological effects patients experience due to low mobility during admission. To inform a scale-up strategy, this study assessed the impact of the initiative based on select process and outcome measures. MATERIALS AND METHODS: Clinical and administrative data were obtained from the hospital Discharge Abstract Database, Research Electronic Data Capture (Redcaps), and Reporting and Learning System for Patient Safety. The variables explored were length of stay, inpatient falls, discharge disposition, pressure injury, patient ambulation, and patient dressed rates. We then used the Interrupted Time Series design for impact analysis. RESULTS: The analysis included discharge abstracts for 32,884 patients and the results showed significant improvements in outcomes at the participating units. The length of stay and inpatient falls were reduced immediately by 1.8 days (B2=-1.80, p = 0.044, 95% CI [-3.54, -0.05]), and 2.2 events (B2=-2.22, p = 005, 95% CI [-3.75, -0.69]). The percentage of patients discharged home increased overtime (B2=.39, p=.006, 95% CI [.11, .66]). Mobilization and dressed rates also improved. CONCLUSIONS: The findings imply the interventions safely mitigated the risk of immobility-induced complications, including deconditioning and hospital-acquired disability.

Immobility during hospitalization is endemic in hospitals and, without intervention, presents a significant risk of physiological deconditioning and subsequent adverse health outcomes, such as functional decline and hospital-acquired disability.This study elevates the importance of preserving functional capacity and dignity of hospitalized patients by encouraging them to get up, dress in personal clothes, and move as much possible.Function-focused initiatives, that include intentional patient ambulation, have the potential to mitigate the risk of immobility-induced deconditioning and other adverse outcomes, such as falls and pressure injury, in older adults.In this study, we have demonstrated the End PJ Paralysis had a positive impact on patient ambulation, length of stay, inpatient falls, and discharge disposition.The study also informed a proposed transformational roadmap to strengthen rehabilitation in the provincial health system and spread the initiative to all the major hospitals to potentially benefit more patients.

Tracking and characterization of a novel conjugative transposon identified by shotgun transposon mutagenesis.

The horizontal transfer of mobile genetic elements (MGEs) is an essential process determining the functional and genomic diversity of bacterial populations. MGEs facilitate the exchange of fitness determinant genes like antibiotic resistance and virulence factors. Various computational methods exist to identify potential MGEs, but confirming their ability to transfer requires additional experimental approaches. Here, we apply a transposon (Tn) mutagenesis technique for confirming mobilization without the need for targeted mutations. Using this method, we identified two MGEs, including a previously known conjugative transposon (CTn) called BoCTn found in Bacteroides ovatus and a novel CTn, PvCTn, identified in Phocaeicola vulgatus. In addition, Tn mutagenesis and subsequent genetic deletion enabled our characterization of a helix-turn-helix motif gene, BVU3433 which negatively regulates the conjugation efficiency of PvCTn in vitro. Furthermore, our transcriptomics data revealed that BVU3433 plays a crucial role in the repression of PvCTn genes, including genes involved in forming complete conjugation machinery [Type IV Secretion System (T4SS)]. Finally, analysis of individual strain genomes and community metagenomes identified the widespread prevalence of PvCTn-like elements with putative BVU3433 homologs among human gut-associated bacteria. In summary, this Tn mutagenesis mobilization method (TMMM) enables observation of transfer events in vitro and can ultimately be applied in vivo to identify a broader diversity of functional MGEs that may underly the transfer of important fitness determinants.

Study on the effect of blood flow restriction training combined with IASTAM on ankle strength and function intervention in athletes with chronic ankle instability in sport dance events.

BACKGROUND: Athletes engaged in sports dance frequently encounter the potential for ankle injuries and instability, factors that may contribute to diminished training efficacy, compromised athletic performance, prolonged recuperation, and heightened susceptibility to recurring injuries. OBJECTIVE: The objective of this study was to investigate the impact of an exercise intervention (comprising blood flow restriction training combined with low-load ankle muscle strength training and balance training) as well as instrument-assisted soft tissue mobilization (IASTM) on the foot and ankle function, strength, and range of motion in sports dance athletes exhibiting ankle instability (CAI). METHODS: Thirty participants exhibiting ankle instability, restriction, or discomfort were recruited and randomly assigned to two groups: the Test group (comprising blood flow restriction training combined with IASTM, n = 15) and the traditional ankle strength training group (n = 15). The intervention spanned 4 weeks, with one session per week. Assessment of the Cumberland Ankle Instability Tool (CAIT), Foot and Ankle Ability Measure (FAAM), and ankle range of motion occurred at three time points: pre-intervention, immediately following the initial intervention, and after 4 weeks of intervention. Ankle strength testing was conducted solely before and after the intervention for comparative analysis. RESULTS: There were no significant variances in baseline characteristics between the two intervention groups. In terms of CAIT scores, both groups exhibited notably higher scores following the initial intervention and after 4 weeks of intervention compared to pre-intervention (P < 0.05). The Test group displayed higher CAIT scores than the control group, signifying a more pronounced enhancement in ankle stability among patients in the Test group. Concerning FAAM scores, both groups significantly enhanced ankle function in CAI patients (P < 0.05), with the Test group demonstrating notably higher FAAM-SPORT scores than the control group (P < 0.05), indicating superior restoration of athletic capability in the Test group. As for improvements in ankle range of motion, both groups demonstrated significant enhancements compared to pre-intervention (P < 0.05). The Test group exhibited significantly superior improvements in dorsiflexion, eversion, and inversion range of motion compared to the control group (P < 0.05), while the control group did not exhibit significant enhancements in plantarflexion and eversion range of motion (P > 0.05). Both groups displayed enhanced ankle strength in CAI patients following the intervention (P < 0.05), with the Test group manifesting notably higher dorsiflexion and inversion strength than the control group (P < 0.05). CONCLUSION: Both blood flow restriction training combined with IASTM and traditional ankle strength and stability training have shown significant improvements in stability, function, strength, and range of motion in CAI patients. Furthermore, the Test group exhibits superior efficacy in ankle stability, daily functional movement, dorsiflexion, and eversion range of motion compared to the control group.

The Influence of COVID-19 on Patient Mobilization and Injury Attributes in the ICU: A Retrospective Analysis of a Level II Trauma Center.

The objectives of this study were to determine the effect of COVID-19 on physical therapy (PT) mobilization of trauma patients and to determine if mobilization affected patient course in the ICU. This retrospective study included patients who were admitted to the ICU of a level II trauma center. The patients were divided into two groups, i.e., those admitted before (n = 378) and after (n = 499) 1 April 2020 when Georgia's COVID-19 shelter-in-place order was mandated. The two groups were contrasted on nominal and ratio variables using Chi-square and Student's t-tests. A secondary analysis focused specifically on the after-COVID patients examined the extent to which mobilization (n = 328) or lack of mobilization (n = 171) influenced ICU outcomes (e.g., mortality, readmission). The two groups were contrasted on nominal and ratio variables using Chi-square and Student's t-tests. The after-COVID patients had higher injury severity as a greater proportion was classified as severely injured (i.e., >15 on Injury Severity Score) compared to the before-COVID patients. After-COVID patients also had a greater cumulative number of comorbidities and experienced greater complications in the ICU. Despite this, there was no difference between patients in receiving a PT consultation or days to mobilization. Within the after-COVID cohort, those who were mobilized were older, had greater Glasgow Coma Scale scores, had longer total hospital days, and had a lesser mortality rate, and a higher proportion were female. Despite shifting patient injury attributes post-COVID-19, a communicable disease, mobilization care remained consistent and effective.
