Complement Terminal Pathway Activation is Associated with Organ Failure in Sepsis Patients

J Inflamm Res. 2022 Jan 8;15:153-162. doi: 10.2147/JIR.S344282. eCollection 2022.

ABSTRACT

BACKGROUND: Complement plays a pivotal role in the immune response to infection. Several studies demonstrated complement activation in sepsis, yet little is known of the relationship of complement terminal pathway activation and the clinical characteristics of sepsis patients. Therefore, we investigated serum C5, soluble C5b-9 (sC5b-9), and soluble CD59 (sCD59) and their relation to organ failure in sepsis patients in the intensive care unit (ICU).

METHODS: In this prospective cohort study, all available patients admitted to the adult ICUs between June 2020 and January 2021 were included. Patients were divided into sepsis and non-sepsis groups according to the Sepsis-3 criteria, serum samples from both groups were investigated for the levels of C5, sC5b-9, and sCD59 using commercial sandwich ELISA kits.

RESULTS: We analyzed 79 serum samples, 36 were from sepsis patients. We found that sepsis patients had significantly lower C5 (83.6± 28.4 vs 104.4± 32.0 µg/mL, p = 0.004) and higher sCD59 (380.7± 170.5 vs 288.9± 92.5 ng/mL, p = 0.016). sC5b-9, although higher in sepsis patients, did not reach statistical significance (1.5± 0.8 µg/mL vs 1.3± 0.7 µg/mL, p = 0.293). Sepsis patients who died during their ICU stay had significantly higher sCD59 compared to those who survived (437.0 ± 176.7 vs 267.8 ± 79.7 ng/mL, p = 0.003, respectively). Additionally, C5 and sCD59 both correlated to SOFA score in the sepsis group (rs = -0.44, P = 0.007 and = 0.43, P = 0.009, respectively), and a similar correlation was not found in the non-sepsis group.

DISCUSSION: In sepsis patients, levels of C5 and sCD59, but not sC5b-9, correlated to the severity of organ damage measured by SOFA. A similar correlation was not found in non-sepsis patients. This indicated that organ damage associated with sepsis led to a more pronounced terminal pathway activation than in non-sepsis patients, it also indicated the potential of using C5 and sCD59 to reflect sepsis severity.

Burden of Pertussis in Individuals with a Diagnosis of Asthma: A Retrospective Database Study in England

J Asthma Allergy. 2022 Jan 11;15:35-51. doi: 10.2147/JAA.S335960. eCollection 2022.

ABSTRACT

PURPOSE: The impact of pertussis in individuals with asthma is not fully understood. We estimated the incidence, health care resource utilization (HCRU), and direct medical costs (DMC) of pertussis in patients with asthma.

PATIENTS AND METHODS: In this retrospective cohort study, the incidence rate of pertussis (identified using diagnostic codes) among individuals aged ≥50 years with an asthma diagnosis was assessed during 2009-2018 using Clinical Practice Research Datalink and Hospital Episode Statistics databases. HCRU and DMC were compared – between patients with diagnoses of asthma and pertussis (asthma+/pertussis+) and propensity score-matched patients with a diagnosis of asthma without pertussis (asthma+/pertussis-) – in the months around the pertussis diagnosis (-6 to +11).

RESULTS: Among 687,105 individuals, 346 had a reported pertussis event (incidence rate: 9.6/100,000 person-years of follow-up; 95% confidence interval: 8.6-10.7). HCRU and DMC were assessed among 314 asthma+/pertussis+ patients and 1256 matched asthma+/pertussis- controls. Baseline HCRU was similar in both cohorts, but increases were observed in the asthma+/pertussis+ cohort from -6 to -1 month before to 2-5 months after diagnosis. Rates of accident and emergency visits, general practitioner (GP)/nurse visits, and GP prescriptions were 4.3-, 3.1-, and 1.3-fold, respectively, in the asthma+/pertussis+ vs asthma+/pertussis- cohorts during the month before diagnosis; GP/nurse visit rates were 2.0- and 1.2-fold during 0-2 and 2-5 months after diagnosis, respectively (all p<0.001). DMC was 1.9- and 1.6-fold during the month before and 2 months from diagnosis, respectively, in the asthma+/pertussis+ vs asthma+/pertussis- cohorts (both p<0.001). During months -1 to +11, DMC in the asthma+/pertussis+ cohort was £370 higher than in the asthma+/pertussis- controls.

CONCLUSION: A pertussis diagnosis among adults aged ≥50 years with asthma resulted in significant increases in HCRU and DMC across several months around diagnosis, suggesting lengthy diagnosis times and highlighting the need for prevention strategies.

Impact of fibrinogen infusion on thrombin generation and fibrin clot structure in patients with inherited afibrinogenemia

Thromb Haemost. 2022 Jan 19. doi: 10.1055/a-1745-0420. Online ahead of print.

ABSTRACT

INTRODUCTION: Inherited afibrinogenemia is a very rare disease characterized by complete absence of fibrinogen in the circulation and an increased risk in both thrombosis and bleeding. Infusion of fibrinogen concentrate (FC) is the main approach for prevention and management of bleeding; however, it has been reported to carry a thrombotic risk.

METHODS: We investigated the impact of a standard dose (40-100 mg/kg) of FC infusion on the thrombin generation (TG) parameters and the fibrin clot structure formed in plasma samples of patients with afibrinogenemia. Blood samples were collected from 20 patients before (T0) and 1 hour after infusion of FC (T1). TG was studied with Calibrated Automated Thrombography. Fibrin clot structure was assessed with turbidimetry and scanning electron microscopy (SEM).

RESULTS: FC infusions (mean Clauss fibrinogen plasma level 1.21 g/L at T1) led to a statistically significant increase in endogenous thrombin potentials (ETP) (p<0.0001) and thrombin peaks (p=0.02). Nevertheless, when compared to healthy controls, patients’ T1 lag times were longer (p=0.002), ETP values were lower (p=0.0003), and thrombin peaks were lower (p<00001). All fibrin polymerization parameters (turbidimetry) obtained at T1 were comparable to those of patients with inherited hypofibrinogenemia matched for fibrinogen plasma levels.

CONCLUSIONS: In summary, fibrinogen infusion with a standard dose of FC increased but did not correct TG and led to formation of fibrin clots similar to those of patients with hypofibrinogenemia. All in all, our results do not support to biological evidence of hypercoagulability induced by FC in patients with afibrinogenemia.

Prospective Evaluation of Transanal Irrigation With a Validated Pediatric Neurogenic Bowel Dysfunction Scoring System

J Pediatr Gastroenterol Nutr. 2022 Jan 18. doi: 10.1097/MPG.0000000000003383. Online ahead of print.

ABSTRACT

OBJECTIVES: To evaluate the efficacy of transanal irrigation (TAI) in pediatric patients with Neurogenic Bowel Dysfunction (NBD) who were treatment naïve to catheter-based TAI using Peristeen® device (Coloplast).

METHODS: Prospective recruitment of patients with NBD who were unsatisfied with their bowel regimen or had no bowel regimen in place, were assessed using the Neurogenic Bowel Dysfunction score (NBDS) before initiating treatment (Time 0) with Peristeen®. NBDS scores were reassessed twice: within the first 6 months (Time 1) of initiation of Peristeen® and again after greater than 6 months of usage with Peristeen® (Time 2).

RESULTS: Over a 26 month period, 104 patients with NBD were enrolled. Mean age was 10.6 years ± 4.7 (range 3-18 years). The NBDS at Time 1 had an average reduction of 14 points from the original score. A similar trajectory was seen at Time 2, with an average reduction of 13 points from original score. There was a statistically significant decrease of 14 points, p < 0.001 at Time 1 and this response was sustained at Time 2 with a statistically significant decrease in scores from initiation by 13 points, p < 0.001. Improved patient satisfaction and quality of life with Peristeen® was seen at Time 1 and Time 2.

CONCLUSION: Our results suggest that Peristeen® can improve quality of life in pediatric patients with NBD. Significant improvement in NBDS occurred in our pediatric patients with NBD when initiated on Peristeen®. Lower scores were seen at both Time 1 and Time 2, which indicated an improvement in their overall NBD.

External Validation of Postpartum Hemorrhage Prediction Models Using Electronic Health Record Data

Am J Perinatol. 2022 Jan 19. doi: 10.1055/a-1745-1348. Online ahead of print.

ABSTRACT

OBJECTIVE: A recent study leveraging machine learning methods found that postpartum hemorrhage (PPH) can be predicted accurately at the time of labor admission in the U.S. Consortium for Safe Labor (CSL) dataset, with a C-statistic as high as 0.93. These CSL models were developed in older data (2002-2008) and used an estimated blood loss (EBL) of ≥1000 mL to define PPH. We sought to externally validate these models using a more recent cohort of births where blood loss was measured using quantitative blood loss (QBL) methods.

STUDY DESIGN: Using data from 5,261 deliveries between February 1, 2019 to May 11, 2020 at a single tertiary hospital, we mapped our electronic health record (EHR) data to the 55 predictors described in previously published CSL models. PPH was defined as QBL ≥1000 mL within 24 hours after delivery. Model discrimination and calibration of the four CSL models were measured using our cohort. In a secondary analysis, we fit new models in our study cohort using the same predictors and algorithms as the original CSL models.

RESULTS: The original study cohort had a substantially lower rate of PPH, 4.8% (7,279/228,438) vs. 25% (1,321/5,261), possibly due to differences in measurement. The CSL models had lower discrimination in our study cohort, with a C-statistic as high as 0.57 (logistic regression). Models refit in our study cohort achieved better discrimination, with a C-statistic as high as 0.64 (random forrest). Calibration improved in the refit models as compared to the original models.

CONCLUSION: The CSL models’ accuracy was lower in a contemporary EHR where PPH is assessed using QBL. As institutions continue to adopt QBL methods, further data are needed to understand the differences between EBL and QBL to enable accurate prediction of PPH.

Optimization of Preoperative Anemia in Lower Limb Joint Replacement Surgery: Assessing the Rates of Allogenic Blood Transfusion and Duration of Hospital Stay

Orthop Nurs. 2022 Jan-Feb 01;41(1):15-20. doi: 10.1097/NOR.0000000000000815.

ABSTRACT

BACKGROUND: Orthopaedic procedures such as total hip and total knee replacements carry a significant risk of postoperative anemia, necessitating allogenic blood transfusions (ABTs), and an increased hospital length of stay.

AIM: Our aim was to investigate whether the implementation of a local protocol designed to detect and treat preoperative anemia resulted in reduced ABT rates and a shorter duration of length of hospital stay (LOS).

METHODS: We retrospectively audited 683 patients undergoing primary hip and knee replacements. We collated data for all patients about hospital length of stay and blood transfusions received. Both descriptive statistics and univariate analysis were performed.

RESULTS: Approximately 21.6% of the cohort within the study who were anemic at preoperative clinic had a significantly increased median LOS of 2 days (p < .001) and an increased packed red cell transfusion rate compared with non-anemic patients (26.1% vs. 2.21%, p < 001). However, treatment of preoperative anemia did not show any significant difference in transfusion rates compared with patients who did not receive corrective treatment. The median LOS was higher by 1 day in the treated group compared with the nontreated cohort (p = .005).

CONCLUSION: There is significant evidence to suggest that preoperative anemia can increase LOS and increase the risk of requiring postoperative blood transfusions. However, anemia should be regarded as a characteristic that can add to the outcome in a cumulative manner, as opposed to an isolated factor. Further research is needed on how to better manage preoperative anemia in order to improve patients’ outcomes.

Trends and Disparities in Pediatric Nonalcoholic Fatty Liver Disease-Associated Hospitalizations in the United States

J Pediatr Gastroenterol Nutr. 2022 Jan 18. doi: 10.1097/MPG.0000000000003384. Online ahead of print.

ABSTRACT

OBJECTIVE: Non-alcoholic fatty liver disease (NAFLD) represents a spectrum of disease characterized by accumulation of fat in the liver and is associated with co-morbidities linked to metabolic syndrome. The prevalence of NAFLD in children has increased in the U.S. over time and with marked racial differences observed in geographically limited studies. This study aims to provide a current, nation-wide analysis of temporal trends of pediatric NAFLD-related hospitalizations and associated co-morbidities as well as assess for racial/ethnic disparities.

METHODS: A cross-sectional study was conducted using the National Inpatient Sample (NIS) from 2004 – 2018 and included NAFLD-associated hospitalizations of children aged 0-17 years of age based on ICD-9/10 diagnosis codes. Rates and patient characteristics analyzed via descriptive statistics and associations via survey logistic regression. Temporal trends assessed via joinpoint regression.

RESULTS: There was an overall increase in pediatric NAFLD-associated hospitalizations with an average annual percent change (AAPC) of 6.6 with highest rates among Hispanic patients (AAPC = 11.1) compared to NH-White (AAPC = 4.1) and NH-Black (AAPC = 2.1). Analysis of race/ethnicity and NAFLD hospitalization showed an increased association in Hispanic patients (OR = 1.64, 95% CI = 1.51-1.77) and a decreased association in Non-Hispanic (NH)-Black patients (OR = 0.49, 95% CI = 0.45-0.54) when compared to NH-White patients.

CONCLUSION: Utilizing a nation-wide database we demonstrated significant increases in NAFLD-associated hospitalizations with highest prevalence and rates seen in Hispanic patients. In addition, gender and comorbidities showed notable correlation to these hospitalization rates displaying the need for further studies on these relationships and highlights the potential for interventions aimed at high-risk groups.

The Effect of Preoperative Education Prior to Hip or Knee Arthroplasty on Immediate Postoperative Outcomes

Orthop Nurs. 2022 Jan-Feb 01;41(1):4-12. doi: 10.1097/NOR.0000000000000814.

ABSTRACT

There is ample research demonstrating improved patient outcomes when using an enhanced recovery program. However, the literature reporting the impact of preoperative education alone prior to hip and knee arthroplasty is conflicting. With the number of these surgical procedures expected to increase in the next few years, the identification of strategies that positively impact outcomes is important. The aim of this study was to evaluate immediate postoperative physical therapy (PT) performance following a total hip or knee arthroplasty in patients who attended a preoperative education class compared with those who did not. This study was a retrospective chart review of 707 hip and knee arthroplasty patients, comparing outcomes based on preoperative educational session attendance. Demographics, comorbidities, length of stay (LOS), discharge disposition, and PT performance were collected from the chart review. Patients who attended the preoperative education class had significantly greater ambulation distances (p < .001), greater degrees of knee flexion (p < .001), and greater degrees of hip flexion (p = .012) on postoperative Day 1. Both hip (p < .001) and knee (p < .001) patients who attended the class had a significantly shorter LOS. The cost benefit analysis indicated a savings of $921.57 in direct costs per knee arthroplasty in those who attended a class. Patients who received preoperative education had greater mobility in the immediate postoperative period and reduced LOS for both hip and knee arthroplasties. Based on this study’s results, preoperative education is effective in improving outcomes and reducing the cost of hip and knee arthroplasties.

Influence of Articular Geometry and Tibial Tubercle Location on Patellofemoral Kinematics and Contact Mechanics

J Appl Biomech. 2022 Jan 19:1-9. doi: 10.1123/jab.2021-0162. Online ahead of print.

ABSTRACT

Trochlear groove geometry and the location of the tibial tubercle, where the patellar tendon inserts, have both been associated with patellofemoral instability and can be modified surgically. Although their effects on patellofemoral biomechanics have been investigated individually, the interaction between the two is unclear. The authors’ aim was to use statistical shape modeling and musculoskeletal simulation to examine the effect of patellofemoral geometry on the relationship between tibial tubercle location and patellofemoral function. A statistical shape model was used to generate new knee geometries with trochlear grooves ranging from shallow to deep. A Monte Carlo approach was used to create 750 knee models by randomly selecting a geometry and randomly translating the tibial tubercle medially/laterally and anteriorly. Each knee model was incorporated into a musculoskeletal model, and an overground walking trial was simulated. Knees with shallow trochlear geometry were more sensitive to tubercle medialization with greater changes in lateral patella position (-3.0 mm/cm medialization shallow vs -0.6 mm/cm deep) and cartilage contact pressure (-0.51 MPa/cm medialization shallow vs 0.04 MPa/cm deep). However, knees with deep trochlear geometry experienced greater increases in medial cartilage contact pressure with medialization. This modeling framework has the potential to aid in surgical decision making.

Nursing Management-Associated Factors Associated with Urinary Tract Infection in Residents from Nursing Home Based on LTCfocus Database

Urol Int. 2022 Jan 19:1-13. doi: 10.1159/000520813. Online ahead of print.

ABSTRACT

INTRODUCTION: The aim of the study was to identify nursing management-associated factors correlated with urinary tract infection (UTI) in residents from nursing homes.

METHODS: The data of 3,393 nursing homes were extracted from LTCfocus database. Variables statistically correlated with UTI rate were identified by Spearman correlation analysis. Tobit regression model was used for finding the factors associated with UTI rate.

RESULTS: The number of beds (β = 0.03, 95% CI: 0.02-0.05), number of occupied beds/the total number of beds (β = 0.05, 95% CI: 0.03-0.07), number of admissions/total number of beds (β = 0.27, 95% CI: 0.11-0.43), the proportions of residents whose primary support is Medicare (β = 0.03, 95% CI: 0.01-0.06), women residents (β = 0.04, 95% CI: 0.02-0.06), White residents (β = 0.02, 95% CI: 0.01-0.03), patients with bladder incontinence (β = 0.03, 95% CI: 0.02-0.05), hypertension patients (β = 0.03, 95% CI: 0.01-0.05), and long-stay residents with daily pain (β = 0.16, 95% CI: 0.12-0.19), hospitalizations per resident year (β = 0.76, 95% CI: 0.30-1.21), and average daily census (β = -0.02, 95% CI: -0.03 to 0.00) were factors associated with UTI rate.

CONCLUSIONS: Nursing homes with more females, White people, and patients with bladder incontinence, hypertension, or daily pain should be cared more and the number of occupied beds and admissions should be controlled to reduce the occurrence of UTI.
