Longitudinal analysis of microcirculatory parameters in gingival tissues after tooth extraction in patients with different risk profiles for wound healing disorders – a pilot study

ObjectivesWe aimed to establish a risk profile for intraoral wound healing disorders based on measurements of microcirculation in gingival tissues.Materials and methodsOxygen saturation (SO2) and blood flow in gingival tissues were measured with tissue spectrometry and laser doppler spectroscopy in 37 patients before/after tooth extractions. Patients were assigned to four groups: anamnestically and periodontally healthy patients (n = 7), anamnestically healthy but suffering from periodontitis (n = 10), anamnestically healthy but smoking and suffering from periodontitis (n = 10) and suffering from diabetes and periodontitis (n = 10). Measurements were performed at three different time points: Baseline measurement (T0), one day post extractionem (p.e.) (T1) and seven days p.e. (T2).ResultsBaseline SO2 values were higher in control patients (p = .038). This effect was most evident in comparison to smokers suffering from periodontitis (p = .042), followed by diabetics suffering from periodontitis (p = .09). An opposite trend was seen for blood flow. Patients suffering from periodontitis demonstrated higher blood flow values (p = .012). Five patients, which belonged to the group of smokers suffering from periodontitis, showed clinically a delayed wound healing.ConclusionDifferences in SO2 and blood flow of gingival tissue could be detected in different groups of patients with existing periodontitis compared to control patients.Clinical RelevanceLower baseline SO2 values could be a warning signal for possible wound healing disorders after oral surgery.

Impact of diabetes on short-term outcomes in patients undergoing coronary artery bypass grafting surgery in acute coronary syndrome.

Diabetes mellitus (DM) is associated with concomitant comorbidities, such as atherosclerosis and cardiovascular disease. Coronary artery bypass grafting (CABG) surgery is the optimal therapy in diabetic patients with triple vessel disease. DM is also known to be a relevant risk factor for higher morbidity and mortality in patients who underwent elective CABG procedures. Data regarding outcomes in diabetic patients in acute coronary syndrome (ACS) is heterogeneous. This study aimed to investigate the impact of DM on short-term outcomes in patients who underwent CABG surgery in ACS. A retrospective propensity score matched (PSM) analysis of 1370 patients who underwent bypass surgery for ACS between June 2011 and October 2019 was conducted. All patients were divided into two groups: non-diabetic group (n = 905) and diabetic group (n = 465). In-hospital mortality was the primary outcome. Secondary outcomes were perioperative myocardial infarction, new onset dialysis, reopening for bleeding and duration of intensive care unit (ICU) stay. A subgroup analysis of patients with insulin-dependent and non-insulin dependent DM was also performed. After performing PSM analysis, baseline characteristics and the preoperative risk profile were comparable between both groups. The proportion of patients who underwent total arterial revascularization (p = .048) with the use of both internal thoracic arteries (p < .001) was significantly higher in the non-diabetic group. The incidence of perioperative myocardial infarction (p = .048) and new onset dialysis (p = .008) was significantly higher in the diabetic group. In-hospital mortality was statistically (p = .907) comparable between the two groups. DM was associated with a higher incidence of adverse outcomes, however with comparable in-hospital mortality in patients who underwent CABG procedure for ACS.

Cardiovascular Risk Profile in Master Paralympic Athletes, a High-Risk Undertreated Population: A Cross-Sectional Longitudinal Study.

Recently, European Society of Cardiology (ESC)validated aprediction model to estimate 10-year fatal and non-fatal cardiovascular disease risk (CVDR) in individuals (aged 40-60 years) without previous cardiovascular disease or diabetes(ESC-SCORE2)and to provide indications for treatment. At present, data describing the CVDR in Paralympic athletes (PAs) are scarce and inconsistent. Therefore,we sought to assess the prevalence of risk factors in PAs to estimate their CVDR through SCORE2. Weenrolled 99 PAs aged ≥40 y.o., who participated at 2012-2022 Paralympic Games, competing in 22 different sport disciplines classified according to sport type (power, skills, endurance and mixed) and disabilities: spinal cord injuries (SCI) and non-SCI. CVDR factors,anthropometric measurements and blood samples were collected. Among the 99 PAs (78% males, mean age 45.7±4.7 y.o.), 52.5% had SCI; 54% were dyslipidemic and 23% were smokers. According to ESC-SCORE2, 29% had high and 1% very-high CVDR. Women (compared to men) and endurance (compared to other sport) exhibited better CV profile. SCI showed no differences when compared with non-SCI for CVDR, excepted for a lower HDL and lower exercise performance.None of the dyslipidemic athlete was on pharmacologically treatment, despitethe altered lipid profile had already been detected at younger age. PAs are a selected population, presenting a high CV risk profile, with 30% showing either high or very-high CVDR according to ESC-SCORE2. Dyslipidemiawas the most common risk factor, underestimated and undertreated, emphasizing the need for specific preventive strategies in this special setting of athletes.

Secondary Prevention in Patients With Stroke Versus Myocardial Infarction: Analysis of 2 National Cohorts.

The implementation of preventive therapies among patients with stroke remains inadequately explored, especially when compared with patients with myocardial infarction (MI), despite sharing similar vascular risk profiles. We tested the hypothesis that participants with a history of stroke have a worse cardiovascular prevention profile in comparison to participants with MI. In cross-sectional analyses within the UK Biobank and All of Us Research Program, involving 14 760 (9193 strokes, 5567 MIs) and 7315 (2948 strokes, 4367 MIs) participants, respectively, we evaluated cardiovascular prevention profiles assessing low-density lipoprotein (<100 mg/dL), blood pressure (systolic, <140 mm Hg; and diastolic, <90 mm Hg), statin and antiplatelet use, and a cardiovascular prevention score that required meeting at least 3 of these criteria. The results revealed that, within the UK Biobank, patients with stroke had significantly lower odds of meeting all the preventive criteria compared with patients with MI: low-density lipoprotein control (odds ratio [OR], 0.73 [95% CI, 0.68-0.78]; P<0.001), blood pressure control (OR, 0.63 [95% CI, 0.59-0.68]; P<0.001), statin use (OR, 0.45 [95% CI, 0.42-0.48]; P<0.001), antiplatelet therapy use (OR, 0.30 [95% CI, 0.27-0.32]; P<0.001), and cardiovascular prevention score (OR, 0.42 [95% CI, 0.39-0.45]; P<0.001). Similar patterns were observed in the All of Us Research Program, with significant differences across all comparisons (P<0.05), and further analysis suggested that the odds of having a good cardiovascular prevention score were influenced by race and ethnicity as well as neighborhood deprivation levels (interaction P<0.05 in both cases). In 2 independent national cohorts, patients with stroke showed poorer cardiovascular prevention profiles and lower adherence to guideline-directed therapies compared with patients with MI. These findings underscore the need to explore the reasons behind the underuse of secondary prevention in vulnerable stroke survivors.

Atrial Fibrillation After Patent Foramen Ovale Closure: Incidence, Pathophysiology, and Management.

This comprehensive review explores the incidence, pathophysiology, and management of atrial fibrillation (AF) following percutaneous closure of patent foramen ovale (PFO). Although AF is considered a common adverse event post PFO closure, its incidence, estimated at <5%, varies based on monitoring methods. The review delves into the challenging task of precisely estimating AF incidence, given subclinical AF and diverse diagnostic approaches. Notably, a temporal pattern emerges, with peak incidence around the 14th day after closure and a subsequent decline after the 45th day, mimicking general population AF trends. The pathophysiological mechanisms behind post PFO closure AF remain elusive, with proposed factors including local irritation, device-related interference, tissue stretch, and nickel hypersensitivity. Management considerations encompass rhythm control, with flecainide showing promise, and anticoagulation tailored to individual risk profiles. The authors advocate for a personalized approach, weighing factors like age, comorbidities, and device characteristics. Notably, postclosure AF is generally considered benign, often resolving spontaneously within 45 days, minimizing thromboembolic risks. Further studies are required to refine understanding and provide evidence-based guidelines.

Association between age at diagnosis and all-cause mortality in type 2 diabetes: the Renal Insufficiency and Cardiovascular Events (RIACE) Italian Multicenter Study.

It is unclear whether type 2 diabetes diagnosed in young adulthood is associated with increased severity than that occurring later in life beyond longer lifetime exposure to hyperglycemia. This study aimed at assessing the independent association of age at type 2 diabetes diagnosis with all-cause mortality. This prospective cohort study enrolled 15,773 Caucasian patients with type 2 diabetes in 19 Italian centers in 2006-2008. Cardiometabolic risk profile and presence of complications and comorbidities were assessed at baseline and participants were stratified by quartiles of age at diabetes diagnosis. All-cause mortality was verified on 31 October 2015. Valid information on vital status was retrieved for 15,656 participants (99.3%). Patients in the lowest quartile had the longest diabetes duration, the worst glycemic control and the highest prevalence of insulin treatment, obesity, atherogenic dyslipidemia, and smoking habits. All complications were inversely associated with age at diabetes diagnosis after adjustment for age and sex, but not after further adjustment for diabetes duration. Percentages of death, Kaplan-Meier estimates, and unadjusted hazard ratios and mortality rates increased from the lowest to the highest quartile. In contrast, when adjusting for age and sex, participants falling in the lowest quartile, showed the highest mortality risk [hazard ratio 1.321 (95% confidence interval 1.196-1.460), P < 0.0001]. However, differences among quartiles disappeared after adjustment for diabetes duration, complications/comorbidities, or other cardiovascular risk factors. Type 2 diabetes onset in young adulthood is associated with increased mortality that is mainly driven by longer diabetes duration favoring the development of complications.

Time-dependent probabilistic tsunami risk assessment: application to Tofino, British Columbia, Canada, subjected to Cascadia subduction earthquakes

A new time-dependent probabilistic tsunami risk model is developed to facilitate the long-term risk management strategies for coastal communities. The model incorporates the time-dependency of earthquake occurrence and considers numerous heterogeneous slip distributions via a stochastic source modeling approach. Tidal level effects are examined by considering different baseline sea levels. The model is applied to Tofino, British Columbia, Canada within the Cascadia subduction zone. High-resolution topography and high-quality exposure data are utilized to accurately evaluate tsunami damage and economic loss to buildings. The results are tsunami loss curves accounting for different elapsed times since the last major event. The evolutionary aspects of Tofino’s time-dependent tsunami risk profiles show that the current tsunami risk is lower than the tsunami risk based on the conventional time-independent Poisson occurrence model. In contrast, the future tsunami risk in 2100 will exceed the time-independent tsunami risk estimate.

Surgical cystogastrostomy: Is it still worthwhile?

The article by Ker et al explores the treatment of peripancreatic fluid collection (PFC). The use of percutaneous drainage, endoscopy, and surgery for managing PFC are discussed. Percutaneous drainage is noted for its low risk profile, while endoscopic cystogastrostomy is more effective due to the wider orifice of the metallic stent. Surgical cystogastrostomy is a definitive treatment with a reduced need for reintervention, especially for cases with extensive collections and significant necrosis. The choice of treatment modality should be tailored to individual patient characteristics and disease factors, considering the expertise available.

Association Between Hemoglobin A1c and Development of Cardiovascular Disease in Canadian Men and WomenWithout Diabetes at Baseline: A Population-Based Study of 608 474 Adults.

We examined the association between hemoglobin A1c (HbA1c) and the development of cardiovascular disease (CVD) in men and women, without diabetes or CVD at baseline. This retrospective cohort study included adults aged 40 to <80 years in Alberta, Canada. Men and women were divided into categories based on a random HbA1c during a 3-year enrollment period. The primary outcome of CVD hospitalization and secondary outcome of combined CVD hospitalization/mortality were examined during a 5-year follow-up period until March 31, 2021. A total of 608 474 individuals (55.2% women) were included. Compared with HbA1c 5.0% to 5.4%, men with HbA1c of 5.5% to 5.9% had an increased risk of CVD hospitalization (adjusted hazard ratio [aHR], 1.12 [95% CI, 1.07-1.19]) whereas women did not (aHR, 1.01 [95% CI, 0.95-1.08]). Men and women with HbA1c of 6.0% to 6.4% had a 38% and 17% higher risk and men and women with HbA1c ≥6.5% had a 79% and 51% higher risk of CVD hospitalization, respectively. In addition, HbA1c of 6.0% to 6.4% and HbA1c ≥6.5% were associated with a higher risk (14% and 41%, respectively) of CVD hospitalization/death in men, but HbA1c ≥6.5% was associated with a 24% higher risk only among women. In both men and women, HbA1c ≥6.0% was associated with an increased risk of CVD and mortality outcomes. The association between CVD and HbA1c levels of 5.5% to 5.9%, considered to be in the "normal" range, highlights the importance of optimizing cardiovascular risk profiles at all levels of glycemia, especially in men.

Facial Features of Hereditary Cancer Predisposition.

In the age of telehealth medicine, an individual's facial features may provide the only physical clues signaling the presence of a heritable cancer predisposition syndrome. These syndromes include APC-associated polyposis, Birt-Hogg-Dubé syndrome, CYLD cutaneous syndrome, hereditary leiomyomatosis and renal cell cancer, multiple endocrine neoplasia, neurofibromatosis type 1, Peutz-Jeghers syndrome, PTEN hamartoma tumor syndrome, and tuberous sclerosis complex 1 and 2, among others. Correctly identifying characteristic features is important for genetic and nongenetic specialists as early detection can enable prompt intervention, improving patient outcomes. Advancements in the availability of genetic testing allow patients and their relatives to have more information about their genetic risk profile than before. These changes in clinical pathways, combined with improvements in screening and risk-reducing treatment, highlight the need to outline the cutaneous and morphologic features of high-risk cancer syndromes for clinicians. In this review, we describe the important facial features of hereditary cancer predisposition, with emphasis on diagnosis, cutaneous and extracutaneous manifestations, and screening.

Computer Hexapod-assisted Orthopaedic Surgery for the Correction of Multiplanar Deformities throughout the Lower Limb.

Computerised hexapod-assisted orthopaedic surgery (CHAOS) is a method by which complex multiplanar, multilevel deformity can be corrected with a high degree of accuracy utilising minimally invasive techniques within a single operative event. This study's aim was to report the reliability, accuracy and magnitude of correction achieved, alongside patient-reported outcomes and risk factors for complications when using the CHAOS technique throughout the lower limb. Retrospective review of medical records and radiographs for consecutive patients who underwent CHAOS for lower limb deformity correction at a tertiary centre between 2012 and 2020. There were 70 cases in 56 patients, with the site of surgery being the femur in 48 cases, proximal tibia in 17 and distal tibia in 5 cases. Multiplanar correction was performed in 43 cases, and multilevel osteotomy was undertaken in 23 cases. Fixation was undertaken with intramedullary nailing (IMN) in 49 cases and locked plates in 21.The maximum corrections were 40° rotation, 20° coronal angulation, 51° sagittal angulation and 62-mm mechanical axis deviation (MAD). Deformity correction was mechanically satisfactory in all patients bar one who was undercorrected requiring revision. The mean patient global impression of change (PGIC) score was 6.2 out of 7.Overall complication rate was 12/70 (17%). Complications from femoral surgery included two nonunions, one case of undercorrection, one case of stiffness, one muscle hernia and one pulmonary embolism. Complications from tibial surgery were one compartment syndrome, one pseudoaneurysm of the anterior tibial artery requiring stenting, one transient neurapraxia of the common peroneal nerve, one locking plate fatigue failure, one seroma and one superficial wound infection. Computerised hexapod-assisted orthopaedic surgery can be used for accurate correction of complex multilevel and multiplanar deformities of both the femur and tibia. The risk profile appears to differ between femoral and tibial surgeries, and also to that of traditional circular frame correction. Patients remain highly satisfied with both the functional and symptomatic outcomes. French JMR, Filer J, Hogan K, et al.

Gendered risks: access to and utilization of sexual and reproductive health services among young migrants in Southwestern Uganda: the role of the 'lending a hand' intervention.

Young migrants may engage in risky behaviours due to social, economic, and psychological challenges as they try to "get by" in their new host communities. This can result in unintended pregnancies, sexually transmitted infections including HIV, and poor mental health outcomes.During a study to test the feasibility and acceptability of an early intervention to reduce the harm of patterns of risk associated with migration, we assessed access to and utilization of sexual and reproductive health services (SRH) among recent migrants (14-24 years) in south-western Uganda. The intervention conducted in 2022/23 involved training peer supporters to provide referral advice and support to young people. Between March-November 2022, 20 young migrants (11 males and 9 females) were purposively selected to participate in two in-depth interviews each to explore their experiences during the intervention. Data were analysed thematically. Women engaged in transactional sex to supplement their low pay while men got involved in risky behaviour once they had earned some money. Many suffered from sexually transmitted infections-related symptoms, were at risk for HIV infection and some women had fears of unwanted pregnancy. While some tried to seek for SRH services from public facilities, poor health service delivery such as long queues and shortages of drugs, discouraged them from going there. Young people tried to access treatment from private facilities but could not afford the costs. The intervention increased knowledge about SRH and supported young people to access services from the public health facilities at no cost thus increasing utilization. Sexual health risks were experienced differently by women and men. The women were likely to experience symptoms related to sexually transmitted infections (including HIV) much earlier than men and this could increase their likelihood to engage with SRH services. The intervention served to increase men's readiness to access SRH services by providing them at a time and place that is convenient. Recognizing the different risk profiles of young people is important in tailoring appropriate interventions to promote equitable access and utilization of SRH services for both genders in this vulnerable population.

Impact of Smokeless Tobacco on Cardiovascular Disease Risk in a Nigerian Metropolitan City.

The use of smokeless tobacco products (STP) as a substitute for tobacco smoking is driving increasing consumption of these products especially in developing countries. The study sought to make comparison of cardiovascular risk profile between chronic STP users and suitably matched tobacco-naïve controls. This is a preliminary report from the cross sectional part of a two-arm prospective study of Smokeless Tobacco Products Composition and Exposure Outcome in Enugu metropolis, Nigeria. Consecutively recruited current Smokeless tobacco users, who had no history of cigarette smoking, aged 18years and above, residing in selected communities in Enugu metropolis, Nigeria were recruited for the study from October 2022 to July 2023. Age and sex matched non-tobacco users from same localities as the study subjects served as controls. Written informed consent to participate in the study was obtained from all study participants. All participants were screened by the investigators, using the study case report forms, to obtain data on medical history, demographic, clinical, laboratory, and electrocardiographic evaluation. Data from 54 STP-users and 54 non-STP-users (mean age 56.58 ± 8.15years) were analyzed. Anthropometric parameters were similar in both groups. Smokeless tobacco users had higher erect and supine blood pressure indices as well asgreater postural drop in systolic blood pressure. The occurrence of diabetes mellitus (20.37% versus 5.56%) and hypertension (25.93%; 11.11%) was significantly higher in the STP-users than in the non-user population, (p = 0.02192 and 0.04751 respectively). Electrocardiographic evaluation showed significantly increased QTc and dispersions of P-wave, QRS and QT intervals as well as reduced PR interval in STP users. Electrocardiographic abnormalities observed in STP users include left ventricular hypertrophy, left atrial enlargement, ST-segment elevation, short PR interval and long QTc. Use of smokeless tobacco products is associated with increased risk burden of diabetes mellitus and hypertensive heart disease. Electrocardiographic findings linked to STP-use in this study are features consistent with arrhythmia, ventricular repolarization abnormality, myocardial hypertrophy and ischaemia, suggesting that smokeless tobacco products are not safe substitutes for tobacco smoking.

An Effective Solution for Investing Funds Through the Robo Advisor Bibit Application

Investment regulates finance such that its value can grow and generate future profits. In Indonesia, investment is increasing yearly. The increase is supported by millennials who have adapted to technology that makes it easier to make digital mutual investments. Although the increase in mutual investment in Indonesia is quite rapid, it does not preclude the possibility that there are still many people who have not invested. The reason people have not invested is that they are afraid to take risks, and their income is low. These reasons can be minimized with the use of technology. Innovation in investing has given rise to modern technological advances such as fintech or financial technology like Robo Advisor. The method used in this study was the Partial Least Squares Structural Equation Modelling analysis technique, which was operated using SmartPLSver. 3 software. Data were collected through questionnaires. The study used quantitative methods and a sample of 200 respondents who had or would have invested through the Bibit application with the use of the Robo Advisor feature. The results of this study found that Robo Advisor can affect millennials’ investing through risk profiling, financial planning, and rebalancing.

Analysis of the Soundness of Government-owned Islamic Banks Before and After a Merger

This paper analyzes the soundness of government-owned Islamic banks before and after a merger. The research variables consist of Risk Profile as measured by Non-Performing Financing (NPF) and Financing to Deposit Ratio (FDR), Good Corporate Governance as measured by Net Open Position (NOP), Earnings as measured by Return on Assets (ROA), Return on Equity (ROE) ) and Operational Efficiency Ratio (OER), and Capital as measured by the Capital Adequacy Ratio (CAR). Three government-owned Islamic banks before merger, namely Bank Rakyat Indonesia (BRI) Sharia, Bank Negara Indonesia (BNI) Sharia, Bank Sharia Mandiri (BSM) and one bank after merger namely Bank Sharia Indonesia (BSI) were selected as research objects. The study uses secondary data for the first quarter of 2019 to the third quarter of 2022. The hypothesis was tested with the Paired Sample T-Test and the Wilcoxon Signed Rank Test. The results show that the ratios of NPF, NOP, ROA, ROE, and OER have significant differences before and after the merger. Meanwhile, the ratios of FDR and CAR have no significant difference before and after the merger. This condition indicates that the ability of Islamic banks to manage FDR and CAR is quite good and remain in the soundness category before and after the merger. This study concludes that some of the soundness ratios of government-owned sharia banks are better after the merger. However, there are two ratios that are not significantly different either before or after the merger. The implication of this research is that the ability of the manager of a government-owned Islamic bank in managing the soundness of a bank greatly determines the sustainability of an Islamic bank. For further research, it is suggested to add the timeframe of the research. Keywords: risk profile, good corporate governance, earning, capital, merger, government owned Islamic banks

Female obesity: clinical and psychological assessment toward the best treatment.

Obesity is a heterogeneous condition which results from complex interactions among sex/gender, sociocultural, environmental, and biological factors. Obesity is more prevalent in women in most developed countries, and several clinical and psychological obesity complications show sex-specific patterns. Females differ regarding fat distribution, with males tending to store more visceral fat, which is highly correlated to increased cardiovascular risk. Although women are more likely to be diagnosed with obesity and appear more motivated to lose weight, as confirmed by their greater representation in clinical trials, males show better outcomes in terms of body weight and intra-abdominal fat loss and improvements in the metabolic risk profile. However, only a few relatively recent studies have investigated gender differences in obesity, and sex/gender is rarely considered in the assessment and management of the disease. This review summarizes the evidence of gender differences in obesity prevalence, contributing factors, clinical complications, and psychological challenges. In addition, we explored gender differences in response to obesity treatments in the specific context of new anti-obesity drugs.

Characterization of Pediatric Infratentorial Arteriovenous Malformations: A Retrospective, Multicenter Cohort Study.

Infratentorial arteriovenous malformations (AVMs) harbor different characteristics compared with supratentorial AVMs. This study aims to explore the unique characteristics of pediatric infratentorial AVMs and their response to single session stereotactic radiosurgery (SRS). The International Radiosurgery Research Foundation database of pediatric patients with AVM (age <18 years) who underwent SRS was retrospectively reviewed. Baseline demographics, AVM characteristics, outcomes, and complications post-SRS were compared between infratentorial and supratentorial pediatric AVMs. Unfavorable outcome was defined as the absence of AVM obliteration, post-SRS hemorrhage, or permanent radiation-induced changes at last follow-up. A total of 535 pediatric AVMs managed with SRS with a median follow-up of 67 months (IQR 29.0-130.6) were included, with 69 being infratentorial and 466 supratentorial. The infratentorial group had a higher proportion of deep location (58.4% vs 30.3%, P = <.001), deep venous drainage (79.8% vs 61.8%, P = .004), and prior embolization (26.1% vs 15.7%, P = .032). There was a higher proportion of hemorrhagic presentation in the infratentorial group (79.7% vs 71.3%, P = .146). There was no statistically significant difference in the odds of an unfavorable outcome (odds ratio [OR] = 1.36 [0.82-2.28]), AVM obliteration (OR = 0.85 [0.5-1.43]), post-SRS hemorrhage (OR = 0.83 [0.31-2.18]), or radiologic radiation-induced changes (OR = 1.08 [0.63-1.84]) between both cohorts. No statistically significant difference on the rates of outcomes of interest and complications were found in the adjusted model. Despite baseline differences between infratentorial and supratentorial pediatric AVMs, SRS outcomes, including AVM obliteration and post-SRS hemorrhage rates, were comparable amongst both groups. SRS appears to have a similar risk profile and therapeutic benefit to infratentorial pediatric AVMs as it does for those with a supratentorial location.

Infection Is Not Associated With Plasma or Cryoprecipitate Transfusion Volumes in Trauma: A Retrospective Study Using the National Trauma Data Bank.

Background: Packed red blood cell (PRBC) transfusion has been shown to increase nosocomial infection risk in the injured population; however, the post-traumatic infectious risk profiles of non-PRBC blood products are less clear. We hypothesized that plasma (fresh frozen plasma [FFP]), platelet (PLT), and cryoprecipitate administration would not be associated with increased rates of nosocomial infections. Patients and Methods: We performed a retrospective, matched, case-control study utilizing the American College of Surgeons National Trauma Data Bank data for 2019. We included all patients who received any volume of PRBC within four hours of presentation. Our outcome of interest was any infection. Controls were matched to cases using individual matching with a desired 1:3 case:control ratio. Bivariable analysis according to infection status, and multivariable logistic regression modeling the development of infection were then performed upon the matched data. Results: A total of 1,563 infectious cases were matched to 3,920 non-infectious controls. First four-hour transfusion volumes for FFP, PLT, and cryoprecipitate in the infection group exceeded those in the control group. The first four-hour FFP transfusion volume (per unit odds ratio [OR], 1.02; 95% confidence interval [CI], 0.99-1.04; p = 0.28) and cryoprecipitate transfusion volume (per unit OR, 1.01; 95% CI, 0.99-1.02; p = 0.43) were similar in cases and controls whereas PLT transfusion volume (per unit OR, 0.92; 95% CI, 0.86-0.98; p = 0.01) was lower in cases of infection than in controls. Conclusions: Fresh frozen plasma, PLT, and cryoprecipitate transfusion volumes were not independent risk factors for the development of nosocomial infection in a trauma population. PLT transfusion volume was associated with less infection.

Abstract PO4-07-05: Clinical evaluation of image-based risk profiling in breast cancer histopathology and comparison to an established gene expression assay

Abstract Background: Among oestrogen receptor (ER)-positive and human epidermal growth factor receptor 2 (HER2)-negative early breast cancer, a significant proportion of patients are categorised as intermediate risk, based on classic clinico-pathological variables, thus providing limited information to guide adjuvant chemotherapy decisions. Prognostic risk profiling is an integrated part of modern breast cancer diagnostics to provide additional risk information for this patient group. Among the established prognostic assays based on gene expression, the Prosigna assay is widely used and provides an individual risk of recurrence (ROR) score and identifies intrinsic subtypes with associated survival outcomes. Pioneering artificial intelligence-based precision diagnostics, Stratipath Breast, is a deep learning-based image analysis tool that utilises digitised histopathological whole slide images to stratify intermediate risk patients in terms of risk of recurrence. Materials and methods: The study included 234 invasive breast tumours from patients with early ER-positive HER2-negative breast cancer, clinically assessed as intermediate risk tumours and eligible for chemotherapy. All tumours had therefore previously been analysed by the Prosigna assay in clinical routine at point of diagnosis between 2020 and 2022 at the Karolinska University Hospital and Södersjukhuset, Stockholm, Sweden. Clinicopathological data including Prosigna results (ROR score, risk group and intrinsic subtype) were extracted from medical records, along with the corresponding archived haematoxylin and eosin (HE)-stained formalin-fixed paraffin-embedded tissue slides. The HE slides were subsequently digitised and analysed by the Stratipath Breast tool. The agreement between the two tests for risk stratification was evaluated in this real-world breast cancer case series. Results: The Prosigna assay classified 76 (32.5%), 110 (47.0%) and 48 (20.5%) tumours as low, intermediate and high risk, respectively. The Stratipath Breast analysis identified 116 (49.6%) tumours as low risk and 118 (50.4%) as high risk. Among Prosigna intermediate risk tumours, 52 (47.3%) were stratified as low risk and 58 (52.7%) as high risk by Stratipath Breast. The overall agreement between the two tests for low risk and high risk groups was 71.0%, with a Cohen’s linear kappa of 0.42. Twelve of the 48 Prosigna high risk cases were classified as Stratipath low risk. ROR scores were higher in the Stratipath high risk group compared to the low risk group (p &amp;lt; 0.001), across all cases as well as in the Prosigna intermediate group. Among the 176 histological grade (NHG) 2 tumours, 97 (55.1%) and 79 (44.9%) were stratified as Stratipath low risk and high risk, respectively, whereas 66 (37.5%), 83 (47.2%) and 27 (15.3%) were stratified as Prosigna low, intermediate and high risk, respectively. The majority of NHG1 (10 of 12) and NHG3 (37 of 46) tumours were stratified as Stratipath low risk and high risk, respectively. For both risk profiling tests, NHG and Ki67 proliferation index differed between risk groups. Conclusions: In this study of clinically assessed intermediate risk ER-positive HER2-negative breast cancer, we observed a moderate agreement between Prosigna and Stratipath Breast for low risk and high risk groups. In addition, image-based risk profiling stratified more of the NHG2 tumours as high risk.

Abstract PO2-19-07: PROOFS – Pre-/perimenopausal patients with HR+/HER2- EBC with intermediate to high clinical and low genomic risk, treated by endocrine treatment (ET) plus ovarian function suppression (OFS) or chemotherapy followed by ET

Abstract Background During the past years, clinical routine has shifted away from relying solely on clinicopathologic factors toward increasing use of multigene expression assays in guiding treatment decisions regarding adjuvant chemotherapy (CT) for hormone receptor-positive (HR+), HER2-negative (HER2-) early breast cancer (EBC) with 0 to 3 positive lymph nodes. In case of a low genomic risk, there is strong consensus in favor of endocrine treatment (ET) alone for postmenopausal patients, regardless of clinical risk (supported by data from planB, ADAPT, RxPonder, TailorX, MINDACT). However, there is still uncertainty regarding optimal therapy for pre- and perimenopausal patients with a similar clinical/genomic risk profile. Since the observed benefit of CT in this patient group may be partly attributable to CT-induced ovarian function suppression (OFS), some of these patients could be spared CT by adding OFS to endocrine therapy. The West German Study Group (WSG) initiated the PROOFS-registry to create a real-world database on how to optimally treat these patients. Eligibility Criteria PROOFS (NCT05792150) aims at the long-term follow up of pre- or perimenopausal patients with HR+/HER2- EBC with an intermediate to high clinical risk of recurrence and low genomic risk measured by MammaPrint(R). Additional endocrine response assessment (Ki67) after a short preoperative endocrine therapy is encouraged. Up to 25% of the study population may have node-positive disease. Participants undergo standard-of-care treatment at physician´s discretion and according to clinical routine, which may include CT neoadjuvant or adjuvant + ET, ET + OFS in premenopausal, or ET +/- OFS in perimenopausal women. Specific Aims PROOFS aims to give insights in the real-world use of OFS and to confirm an excellent outcome in pre-/perimenopausal women with HR+/HER2- early BC with an intermediate to high clinical risk of recurrence and low genomic risk treated by ET +/- OFS alone (without CT). In addition, quality of life is captured. Statistical Methods The primary objective is to demonstrate the 5-year distant recurrence-free interval (dRFI) in patients treated by ET +/- OFS alone. The null hypothesis H(0) is: 5-year dRFI &amp;lt; 92%. Secondary endpoints for all patients are 5- and 10-year dRFI, distant disease-free survival (dDFS), overall survival (OS), breast cancer-free interval (BCFI), quality of life (QLQ BR23 and QLQ-C30) and therapy adherence. Cox regression models, Kaplan-Meier method and log-rank tests will be applied for survival analysis. Linear mixed models will be utilized to quantitatively describe the course of quality of life-scores as well as therapy adherence, and to conduct group comparisons. Present and Target Accrual The study is open for recruitment of 1500 patients (approximately 20% receiving CT and 80% receiving ET +/- OFS) at up to 100 centers in Germany (June 2023: 24 open for recruitment).
