Increases and decreases in liver stiffness measurements are independently associated with the risk of liver-related events in NAFLD.

The clinical significance of change in liver stiffness measurement (LSM) by vibration-controlled transient elastography (VCTE) in patients with NAFLD is not well-understood. We prospectively defined rates of progression to and regression from LSM-defined compensated advanced chronic liver disease (cACLD) and their associations with liver-related events (LRE). Participants in the NASH Clinical Research Network NAFLD Database 2 and 3 studies were included. Progression to cACLD was defined as reaching LSM ≥10 kPa in participants with LSM < 10 kPa on initial VCTE; regression from cACLD was defined as reaching LSM < 10 kPa in participants with baseline LSM ≥ 10 kPa. LRE was defined ≥1 of the following: liver-related death, liver transplant, hepatocellular carcinoma, MELD>15, development of varices, or hepatic decompensation. Univariate and multivariable interval-censored Cox regression analyses were used to compare the cumulative LRE probability by LSM progression and regression status. In 1,403 participants, 89 LRE developed over a mean follow-up of 4.4 years with an LRE annual incidence rate of 1.5 (95% CI: 1.2-1.8). In participants at risk, progression to LSM ≥10 or ≥15 kPa occurred in 29% and 17%, whereas regression to LSM <10 or <15 Kpa occurred in 44% and 49%. Progressors to cACLD (≥10 kPa) experienced a higher cumulative LRE rate versus non-progressors [16% vs 4%, Adj.HR: 3.8, 95% CI [2.3-6.5], P < 0.01]. Regressors from cACLD (to LSM <10 kPA) experienced a lower LRE rate than non-regressors [7% vs 32%%, Adj.HR: 0.25, 95% CI [0.10-0.61], P < 0.01] CONCLUSIONS: Change in LSM over time is independently and bi-directionally associated with risk of LRE and is a non-invasive surrogate for clinical outcomes in patients with NAFLD. (Word count: 275) IMPACT AND IMPLICATIONS: The prognostic value of change in LSM in patients with NAFLD is not well understood. In this large prospective study of patients with NAFLD and serial VCTE exams, baseline and dynamic changes in LSM were associated with the risk of developing liver-related events. LSM is a useful non-invasive surrogate of clinical outcomes in patients with NAFLD.

Twenty-Year Follow-Up of Large-Volume Low-Grade Urothelial Carcinoma: Long-Term Outcomes in Patients Undergoing Ureteroscopic Versus Nephroureterectomy Therapy

Significance of absolute neutrophil count before allogeneic hematopoietic stem cell transplantation in adult patients with aplastic anemia.

The impact of absolute neutrophil count (ANC) before allogenic hematopoietic stem cell transplantation (HSCT) on the outcomes for patients with aplastic anemia (AA) remains unclear. We retrospectively evaluated the relationship between ANC before transplantation and patient outcomes, involving 883 adult Japanese patients with AA who underwent allogeneic HSCT as their first transplantation between 2008 and 2020. Patients were divided into three groups based on ANC: 0/µL (n = 116); 1-199 (n = 210); and ≥ 200 (n = 557). In the low ANC groups (ANC < 200), patient age was higher, previous anti-thymocyte globulin (ATG) treatments were infrequent, duration from diagnosis to transplantation was shorter, hematopoietic cell transplantation-comorbidity index (HCT-CI) was higher, ATG-based conditioning was used infrequently, and peripheral blood stem cell from related donor and cord blood were used frequently. In multivariate analysis, patient age, previous ATG treatment, HCT-CI, stem cell source, and ANC before transplantation were significantly associated with 5-year overall survival (OS) ("ANC ≥ 200": 80.3% vs. "ANC 1-199": 71.7% vs. "ANC 0": 64.4%). The cumulative incidence of bacterial infection, invasive fungal disease, and early death before engraftment were significantly higher in the low ANC groups. Among patients with ANC of zero before transplantation, younger patient age, shorter duration from diagnosis to transplantation, HCT-CI of 0, and bone marrow from related donor as stem cell source were significantly associated with better OS. Consequently, ANC before allogeneic HSCT was found to be a significant prognostic factor in adult patients with AA. Physicians should pay attention to ANC before transplantation.

What are the Optimal Systemic Treatment Options for Rhabdomyosarcoma?

Rhabdomyosarcoma, a soft tissue sarcoma commonly observed in childhood, requires multidisciplinary treatment, including surgical tumor resection, chemotherapy, and radiation therapy. Although long-term survival can be expected in patients with localized rhabdomyosarcoma, the clinical outcomes in patients with metastatic or unresectable rhabdomyosarcoma remain unsatisfactory. To improve the outcomes of rhabdomyosarcoma, it is important to explore effective systemic treatments for metastatic rhabdomyosarcoma. Currently, multiagent chemotherapy comprising vincristine, actinomycin D, and ifosfamide/cyclophosphamide remains standard systemic treatment for rhabdomyosarcoma. On the other hand, new treatment, such as immune checkpoint inhibitors and molecular targeted drugs, have demonstrated superior clinical outcomes compared to those of standard treatments in various type of malignancies. Therefore, it is necessary to assess the efficacies of these treatments in patients with rhabdomyosarcoma. Recent clinical studies have shown efficacies and safeties of temozolomide combined with vincristine/irinotecan, olaratumab combined with doxorubicin or vincristine/irinotecan, and long-term maintenance therapy. Furthermore, basic researches demonstrated new therapeutic targets. Future studies using these approaches are required to assess their clinical significances.

Zebularine potentiates anti-tumor immunity by inducing tumor immunogenicity and improving antigen processing through cGAS-STING pathway

DNA methylation is an important epigenetic mechanism involved in the anti-tumor immune response, and DNA methyltransferase inhibitors (DNMTi) have achieved impressive therapeutic outcomes in patients with certain cancer types. However, it is unclear how inhibition of DNA methylation bridges the innate and adaptive immune responses to inhibit tumor growth. Here, we report that DNMTi zebularine reconstructs tumor immunogenicity, in turn promote dendritic cell maturation, antigen-presenting cell activity, tumor cell phagocytosis by APCs, and efficient T cell priming. Further in vivo and in vitro analyses reveal that zebularine stimulates cGAS-STING-NF-κB/IFNβ signaling to enhance tumor cell immunogenicity and upregulate antigen processing and presentation machinery (AgPPM), which promotes effective CD4+ and CD8+ T cell-mediated killing of tumor cells. These findings support the use of combination regimens that include DNMTi and immunotherapy for cancer treatment.

Laparotomy for Traumatic Splenic Injury: Should we Increase our Efforts to Preserve the Spleen?

Abstract Background In trauma laparotomy the spleen is removed very liberally, and often little effort is made for splenic preservation. Aims The aim of this study was to assess the effect of surgical management (splenic repair vs. splenectomy) on outcomes in patients undergoing trauma laparotomy. Methods This is a trauma registry (TQIP) study (2013–2019), including adult patients with severe splenic injuries (grades III-V) undergoing trauma laparotomy. Characteristics and outcomes of patients who underwent splenic repair vs. splenectomy within 6 hours of admission were compared using different statistical approaches, i.e. 1:1 exact matching with consecutive conditional logistic regression analysis as primary analysis, multivariable logistic regression, propensity score matching and inverse-probability weighting as sensitivity analyses. The primary outcome was in-hospital mortality. Results A total of 11,247 patients with a severe splenic injury undergoing trauma laparotomy within 6 hours of admission were identified. Of these, 10,820 (96.2%) patients underwent splenectomy and 427 (3.8%) patients splenic repair within 6 hours of admission. Among patients who underwent an initial splenic salvage procedure, 23 (5.3%) patients underwent a splenectomy during the subsequent hospital stay. 400 patients with splenic preservation, were matched with 400 patients who underwent splenectomy (matched for age, sex, hypotension, trauma mechanism as well as AIS spleen grades 3,4,5 and AIS groups (AIS 0-2, AIS 3, AIS 4-5) for head, face, neck, thorax, spine, and lower &amp; upper extremity). The mortality was significantly lower in the group of patients with splenic repair (6.5% vs 12.8%, p=0.002). The mortality benefit was subsequently verified by conditional regression analysis (aOR 0.4, CI 95% 0.2; 0.9). Multivariable logistic regression, propensity score matching, and inverse-probability weighting confirmed the lower mortality in the splenic repair group. Conclusion In trauma laparotomy splenic repair was independently associated with lower mortality compared with splenectomy. Splenectomy was required in approximately 5% of the patients after initial splenic repair. The findings provide evidence that efforts for spleen preservation in trauma laparotomy should be considered in selected cases.

Cannabis Use Disorder Associated With Increased Risk of Postoperative Complications After Hip or Knee Arthroplasties: A Meta-analysis of Observational Studies.

With the legalization of marijuana in the United States, the number of patients with cannabis use disorder (CUD) in the joint arthroplasty population has increased markedly. The primary purpose of this meta-analysis was to determine whether there were differences in clinical and economic outcomes after total joint arthroplasty (TJA) between patients with and without perioperative CUD. We searched PubMed, Embase, Scopus, and Web of Science databases up to July 2018 to identify all eligible studies investigating the association of CUD with postoperative outcomes in patients undergoing TJA. Postoperative outcomes assessed consisted of complications, readmission, length of stay (LOS), implant revision, and cost of care. For dichotomous outcomes, pooled odds ratios (OR) with 95% confidence intervals (CI) were calculated using a random effects model. We identified 10 retrospective cohort studies with a total of 17,981,628 study participants. Patients with CUD had significantly higher odds of medical complications (OR 1.33 [95% CI 1.07 to 1.66], P = 0.01) and implant-related complications (OR 1.75 [95% CI: 1.64 to 1.88], P < 0.00001) than noncannabis users. Specifically, CUD was associated with significantly increased odds of cardiac complications (OR 1.95 [95% CI 1.50 to 2.54], P < 0.00001), cerebrovascular accidents (OR 2.06 [95% CI 1.66 to 2.57], P < 0.00001), postoperative infections (OR 1.68 [95% CI 1.34 to 2.10], P < 0.00001), periprosthetic fracture (OR 1.42 [95% CI 1.19 to 1.70], P < 0.0001), mechanical loosening (OR 1.54 [95% CI 1.42 to 1.66], P < 0.00001), and dislocation/instability (OR 1.88 [95% CI 1.32 to 2.68], P = 0.0005). Longer LOS and higher cost of care were also found in patients with CUD. This study strengthens the body of evidence that patients with CUD face higher risk of postoperative complications and greater financial burden after knee and hip arthroplasties. Physicians should inform patients about adverse outcomes and undertake appropriate risk adjustments before elective orthopaedic surgery. Level III.

Perioperative Nivolumab in Resectable Lung Cancer

BackgroundStandard treatment with neoadjuvant nivolumab plus chemotherapy significantly improves outcomes in patients with resectable non–small-cell lung cancer (NSCLC). Perioperative treatment (i.e., neoadjuvant therapy followed by surgery and adjuvant therapy) with nivolumab may further improve clinical outcomes.MethodsIn this phase 3, randomized, double-blind trial, we assigned adults with resectable stage IIA to IIIB NSCLC to receive neoadjuvant nivolumab plus chemotherapy or neoadjuvant chemotherapy plus placebo every 3 weeks for 4 cycles, followed by surgery and adjuvant nivolumab or placebo every 4 weeks for 1 year. The primary outcome was event-free survival according to blinded independent review. Secondary outcomes were pathological complete response and major pathological response according to blinded independent review, overall survival, and safety.ResultsAt this prespecified interim analysis (median follow-up, 25.4 months), the percentage of patients with 18-month event-free survival was 70.2% in the nivolumab group and 50.0% in the chemotherapy group (hazard ratio for disease progression or recurrence, abandoned surgery, or death, 0.58; 97.36% confidence interval [CI], 0.42 to 0.81; P<0.001). A pathological complete response occurred in 25.3% of the patients in the nivolumab group and in 4.7% of those in the chemotherapy group (odds ratio, 6.64; 95% CI, 3.40 to 12.97); a major pathological response occurred in 35.4% and 12.1%, respectively (odds ratio, 4.01; 95% CI, 2.48 to 6.49). Grade 3 or 4 treatment-related adverse events occurred in 32.5% of the patients in the nivolumab group and in 25.2% of those in the chemotherapy group.ConclusionsPerioperative treatment with nivolumab resulted in significantly longer event-free survival than chemotherapy in patients with resectable NSCLC. No new safety signals were observed. (Funded by Bristol Myers Squibb; CheckMate 77T ClinicalTrials.gov number, NCT04025879.)

Contemporary Advances in Cardiac Remote Monitoring: A Comprehensive, Updated Mini-Review

Over the past decade, remote monitoring (RM) has become an increasingly popular way to improve healthcare and health outcomes. Modern cardiac implantable electronic devices (CIEDs) are capable of recording an increasing amount of data related to CIED function, arrhythmias, physiological status and hemodynamic parameters, providing in-depth and updated information on patient cardiovascular function. The extensive use of RM for patients with CIED allows for early diagnosis and rapid assessment of relevant issues, both clinical and technical, as well as replacing outpatient follow-up improving overall management without compromise safety. This approach is recommended by current guidelines for all eligible patients affected by different chronic cardiac conditions including either brady- and tachy-arrhythmias and heart failure. Beyond to clinical advantages, RM has demonstrated cost-effectiveness and is associated with elevated levels of patient satisfaction. Future perspectives include improving security, interoperability and diagnostic power as well as to engage patients with digital health technology. This review aims to update existing data concerning clinical outcomes in patients managed with RM in the wide spectrum of cardiac arrhythmias and Hear Failure (HF), disclosing also about safety, effectiveness, patient satisfaction and cost-saving.

Our Experience with Primary Trapeziometacarpal Implant Arthroplasty in Severely Comminuted Rolando Fractures

Abstract Background The concept of primary joint replacement in severely comminuted fractures in elderly patients has proven to be a suitable treatment option in the shoulder, elbow and knee joint. Comminuted intra-articular fractures of the first metacarpal base can pose significant technical challenges, and no established gold standard treatment currently exists. Conventional methods like open reduction and internal fixation or external fixation are commonly employed, emphasizing the importance of anatomical reduction for restoring the articular surface. However, achieving articular surface congruity is often unattainable in severely comminuted intra-articular fractures, leading to short-term joint stiffness and instability, as well as long-term complications like secondary osteoarthritis. Aims This case report aims to share our experience with the use of primary trapeziometacarpal implant arthroplasty in the treatment of two patients with severely comminuted Rolando fractures. Methods In two cases of comminuted Rolando fractures, a primary trapeziometacarpal prosthesis (MAÏA™) was implanted based on preoperative decision-making facilitated by 3D-CT analysis. Patient’s visual analogue score for pain, range of motion, pinch and grip strength compared to the contralateral side were asked and examined. Results Both patients exhibited successful adaptation to their daily routines within a three-month postoperative period. No complications, such as cup or stem loosening or dislocation, were identified. Both patients almost reached equal range of motion, pinch and grip strength compared to the contralateral side. Conclusion The use of primary trapeziometacarpal implant arthroplasty seems to be a viable alternative for managing severely comminuted Rolando fractures, particularly in elderly patients and those with pre-existing osteoarthritis. This approach offers promising outcomes. Studies with other implant arthroplasties have shown better outcomes in patients treated primarily, than after several failed surgeries. We suggest the same is true for the trapeziometacarpal joint. Further studies are necessary to validate the efficacy of this intervention in a larger cohort of patients.

Perinatal Use and Discontinuation of Disease-Modifying Antirheumatic Drugs: Outcomes of Patients Seen at a Pregnancy and Rheumatic Diseases Clinic.

Managing rheumatic disease activity using pregnancy-compatible medications is essential for reducing adverse maternal and fetal outcomes. We characterized medication use and discontinuation before, during, and after pregnancy, among female patients with rheumatic diseases attending a targeted pregnancy and rheumatic diseases clinic. We conducted a cross-sectional medical record review of female patients with rheumatic diseases at a Canadian clinic between January 2017 and July 2020. Patients were categorized by pregnancy stage at their latest clinic visit: (1) preconception; (2) pregnant; (3) postpartum. We assessed use of conventional, biologic, and targeted synthetic disease-modifying antirheumatic drugs (DMARDs), prednisone, and nonsteroidal anti-inflammatory drugs across 6 perinatal windows: 24 and 12 months preconception, each pregnancy trimester, and 3 months postpartum. We reported adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for medication discontinuation in the first trimester and subsequent disease flare. Of 230 included patients, 85 (37.0%), 12 (5.2%), and 133 (57.8%) were preconception, pregnant, and postpartum, respectively. Approximately half experienced at least 1 disease flare during each pregnancy stage (56.4% preconception, 58.1% during pregnancy, and 53.7% postpartum). Most used at least 1 DMARD throughout the perinatal period (82.6% preconception, 55.6% during pregnancy, and 45.1% postpartum). Overall, 25.5% discontinued at least 1 DMARD in the first trimester. DMARD discontinuation was associated with disease flare during pregnancy (aOR, 1.49; 95% CI, 0.55-4.03; p = 0.87) and postpartum (aOR, 3.09; 95% CI, 0.83-11.47; p = 0.09). Patients receiving care at a pregnancy and rheumatic disease clinic show perinatal medication use patterns consistent with recent recommendations and clinical guidelines.

Non-invasive biomarkers prognostic of decompensation events in NASH cirrhosis: a systematic literature review.

Liver cirrhosis due to nonalcoholic steatohepatitis (NASH) is a life-threatening condition with increasing incidence world-wide. Although its symptoms are unspecific, it can lead to decompensation events such as ascites, hepatic encephalopathy, variceal hemorrhage, and hepatocellular carcinoma (HCC). In addition, an increased risk for cardiovascular events has been demonstrated in patients with NASH. Pharmacological treatments for NASH cirrhosis are not yet available, one of the reasons being the lack in surrogate endpoints available in clinical trials of NASH cirrhosis. The feasibility of non-invasive prognostic biomarkers makes them interesting candidates as possible surrogate endpoints if their change following treatment would result in better outcomes for patients in future clinical trials of NASH cirrhosis. In this systematic literature review, a summary of the available literature on the prognostic performance of non-invasive biomarkers in terms of cardiovascular events, liver-related events, and mortality is outlined. Due to the scarcity of data specific for NASH cirrhosis, this review includes studies on NAFLD whose evaluation focuses on cirrhosis. Our search strategy identified the following non-invasive biomarkers with prognostic value in studies of NASH patients: NAFLD fibrosis score (NFS), Fibrosis-4 (FIB-4), aspartate aminotransferase (AST) to platelet ratio index (APRI), enhanced liver fibrosis (ELF™), BARD (BMI, AST/ALT (alanine aminotransferase) ratio, diabetes), Hepamet Fibrosis Score (HFS), liver enzymes (AST + ALT), alpha-fetoprotein, platelet count, neutrophil to lymphocyte ratio (NLR), Lysyl oxidase-like (LOXL) 2, miR-122, liver stiffness, MEFIB (liver stiffness measured with magnetic resonance elastography (MRE) + FIB-4), and PNPLA3 GG genotype. The aim of the present systematic literature review is to provide the reader with a summary of the non-invasive biomarkers with prognostic value in NASH cirrhosis and give an evaluation of their utility as treatment monitoring biomarkers in future clinical trials.

Excellent Survival With a Focus on Pulmonary Artery Reinterventions After the Arterial Switch Operation.

Background: We sought to evaluate the outcomes in patients who underwent the arterial switch operation (ASO) over a 20-year period at a single institution. Methods: The current study is a retrospective review of 180 consecutive patients who underwent the ASO for biventricular surgical correction of dextro-transposition of the great arteries (d-TGA) between 2002 and 2022. Results: Among 180 patients, 121 had TGA-intact ventricular septum, 47 had TGA-ventricular septal defect and 12 had Taussig-Bing Anomaly (TBA). The median follow-up time was 6.7 years (interquartile range: 3.9-8.7 years). There were five early (2.8%) and one late (0.6%) mortality. Survival was 96.6% at one year and beyond. Reoperations were performed in 31 patients (17%). Taussig Bing Anomaly was found to increase the risk of reoperation by 17 times (P < .0001). A total of 37 (21%) patients underwent 53 reinterventions (14 surgical procedures, 39 catheter interventions) specifically addressing pulmonary artery (PA) stenosis. Freedom from PA reintervention was 97%, 87%, 70%, and 55% at 1, 5, 10, and 15 years, respectively. By bivariable analysis, TBA (P = .003, odds ratio [OR]: 6.4, 95% confidence interval [CI]: 1.9-21.7), mild PA stenosis at discharge (P ≤ .001, OR: 6.1, 95% CI: 2.7-13.6), and moderate or severe PA stenosis at discharge (P ≤ .001, OR: 12.7, 95% CI: 5-32.2) were identified as predictors of reintervention on PA. In the last follow-up of 174 survivors, 24 patients (14%) had moderate or greater PA stenosis, two (1%) had moderate neoaortic valve regurgitation, and 168 were New York Heart Association status I. Conclusions: Our results demonstrated excellent survival and functional status following the ASO for d-TGA; however, patients remain subject to frequent reinterventions especially on the pulmonary arteries.

Distinct immunometabolic signatures in circulating immune cells define disease outcome in acute-on-chronic liver failure.

Acute-on-chronic liver failure (ACLF) is a complication of cirrhosis characterized by multiple organ failure and high short-term mortality. The pathophysiology of ACLF involves elevated systemic inflammation leading to organ failure, along with immune dysfunction that heightens susceptibility to bacterial infections. However, it is unclear how these aspects are associated with recovery and non-recovery in ACLF. Here we mapped the single-cell transcriptome of circulating immune cells from ACLF-, acute decompensated (AD) cirrhosis patients and healthy individuals. We further interrogate how these findings as well as immunometabolic- and functional profiles associate with ACLF recovery (ACLF-R) or non-recovery (ACLF-NR). Our analysis unveiled two distinct states of classical monocytes (cMon). Hereto, ACLF-R cMons were characterized by transcripts associated with immune- and stress tolerance, including anti-inflammatory genes such as RETN and LGALS1. Additional metabolomic- and functional validation experiments implicated an elevated oxidative phosphorylation metabolic program as well as an impaired ACLF-R cMon functionality. Interestingly, we observed a common stress-induced tolerant state, oxidative phosphorylation program and blunted activation among lymphoid populations in ACLF-R patients. Conversely, ACLF-NR cMon featured elevated expression of inflammatory- and stress response genes such as VIM, LGALS2, and TREM1 along with blunted metabolic activity and increased functionality. This study identifies distinct immuno-metabolic cellular states that contribute to disease outcome in ACLF patients. Our findings provide valuable insights into the pathogenesis of ACLF, shedding light on factors driving either recovery or non-recovery phenotypes which may be harnessed as potential therapeutic targets in the future.

Preoperative Education is Associated with Adherence to Downstream Components and Outcomes in a Colorectal Surgery Enhanced Recovery Program

Objective: This study evaluated the association between preoperative education and adherence to downstream components of enhanced recovery programs (ERPs) and surgical outcomes among patients undergoing elective colorectal surgery. Background: ERPs improve outcomes for surgical patients. While preoperative education is an essential component of ERPs, its relationship with other components is unclear. Methods: This was a retrospective cohort study of all ERP patients undergoing elective colorectal surgery from 2019 to 2022. Our institutional ERP database was linked with American College of Surgeons National Surgical Quality Improvement Program data and stratified by adherence to preoperative education. Primary outcomes included adherence to individual ERP components and secondary outcomes included high-level ERP adherence (&gt;70% of components), length of stay (LOS), readmissions, and 30-day complications. Results: A total of 997 patients were included. The mean (SD) age was 56.5 (15.8) years, 686 (57.3%) were female, and 717 (71.9%) were white. On adjusted analysis, patients who received preoperative education (n = 877, 88%) had higher adherence rates for the following ERP components: no prolonged fasting (estimate = +19.6%; P &lt; 0.001), preoperative blocks (+8.0%; P = 0.02), preoperative multimodal analgesia (+18.0%; P &lt; 0.001), early regular diet (+15.9%; P &lt; 0.001), and postoperative multimodal analgesia (+6.4%; P &lt; 0.001). High-level ERP adherence was 13.4% higher (P &lt; 0.01) and LOS was 2.0 days shorter (P &lt; 0.001) for those who received preoperative education. Classification and regression tree analysis identified preoperative education as the first-level predictor for adherence to early regular diet, the second-level predictor for LOS, and the third-level predictor for ERP high-level adherence. Conclusion: Preoperative education is associated with adherence to ERP components and improved surgical outcomes.

Physiotherapy students’ oral health related knowledge, attitudes and practices at an identified institution of higher learning in KwaZulu-Natal, South Africa

Background Oral self-care health is integral to general health. However limited studies reflect physiotherapy students’ dental practices such as frequency of toothbrushing, toothbrush replacement, use of oral rinses, dental flossing, use of interdental aids or knowledge of dental plaque. Study objectives This study assessed knowledge, perceptions and oral self-care practices among physiotherapy students. This descriptive cross-sectional survey recruited second- third-, and fourth-year physiotherapy students at an identified training institution in South Africa by means of a self-administered questionnaire ResultsA total of 137 students participated in the study with a response rate of 83%. Participants indicated that 58%(n=79) had good knowledge and 85% (n=117) reported oral self-care practices. Almost all participants (99%; n=136) used a brush with toothpaste; 76% (n=104) brushed twice daily; 53% (n=72) replaced their toothbrush every 3 months and 48% (n=66) rinsed their mouth after eating. More than two-thirds of the study sample (62%; n= 84) used an interdental aid and (37%; n=50) reported dental visits once a year with (74%; n=100) only when necessary. From these 96% (n=132) experienced barriers such as costs (54%; n=71) and inadequate time (42%; n = 55). The majority of participants (72%; n=98) supported oral self-care be included in the physiotherapy curriculum. ConclusionAlthough there were inconsistencies in physiotherapy students’ reported oral health-related knowledge, perceptions and self-care practices, the majority of participants supported the inclusion of dental health into the undergraduate physiotherapy curriculum. This will enhance interprofessional education and improve oral health outcomes for both students and patients.

Proteomic assay for rapid characterisation of Staphylococcus aureus antimicrobial resistance mechanisms directly from blood cultures.

Staphylococcus aureus is one of the most common pathogens causing bloodstream infection. A rapid characterisation of resistance to methicillin and, occasionally, to aminoglycosides for particular indications, is therefore crucial to quickly adapt the treatment and improve the clinical outcomes of septic patients. Among analytical technologies, targeted liquid chromatography-tandem mass spectrometry (LC-MS/MS) has emerged as a promising tool to detect resistance mechanisms in clinical samples. A rapid proteomic method was developed to detect and quantify the most clinically relevant antimicrobial resistance effectors in S. aureus in the context of sepsis: PBP2a, PBP2c, APH(3')-III, ANT(4')-I, and AAC(6')-APH(2''), directly from positive blood cultures and in less than 70min including a 30-min cefoxitin-induction step. The method was tested on spiked blood culture bottles inoculated with 124 S.aureus, accounting for the known genomic diversity of SCCmec types and the genetic background of the strains. This method provided 99% agreement for PBP2a (n = 98/99 strains) detection. Agreement was 100% for PBP2c (n = 5/5), APH(3')-III (n = 16/16), and ANT(4')-I (n = 20/20), and 94% for AAC(6')-APH(2'') (n = 16/17). Across the entire strain collection, 100% negative agreement was reported for each of the 5 resistance proteins. Additionally, relative quantification of ANT(4')-I expression allowed to discriminate kanamycin-susceptible and -resistant strains, in all strains harbouring the ant(4')-Ia gene. The LC-MS/MS method presented herein demonstrates its ability to provide a reliable determination of S. aureus resistance mechanisms, directly from positive blood cultures and in a short turnaround time, as required in clinical laboratories.
