Fall Injuries

The aim of this study was to find out the risk factors through analysis of seven medical malpractice judgments related to fall injuries. The risk factors were analysed by using the framework that approaches falls from a systems perspective and comprised people, organisational or environmental factors, with each factor being comprised of subfactors. The risk factors found in each of the seven judgments were aggregated into one framework. The risk factors related to patients (i.e. the people factor) were age, pain, related disease, activities and functional status, urination state, cognitive function impairment, past history of fall, blood transfusion, sleep endoscopy state and uncooperative attitude. The risk factors related to the medical staff and caregivers (i.e. people factor) were observation negligence, no fall prevention activities and negligence in managing high-risk group for fall. Organisational risk factors were a lack of workforce, a lack of training, neglecting the management of the high-risk group, neglecting the management of caregivers and the absence of a fall prevention procedure. Regarding the environment, the risk factors were found to be the emergency room, chairs without a backrest and the examination table. Identifying risk factors is essential for preventing fall accidents, since falls are preventable patient-safety incidents. Falls do not happen as a result of a single risk factor. Therefore, a systems approach is effective to identify risk factors, especially organisational and environmental factors.

The need to assess anxiety levels so that they do not cause complications in pregnancy. The purpose of this study is to determine differences in anxiety levels of third trimester pregnant women based on pregnancy risk factor groups. The study design uses comparative analytics with cross-sectional approaches. This research uses purposive sampling technique. A sample of 51 people who met the inclusion criteria was recorded in a cohort with 28-37 weeks' gestation in the Gribig Community Health Center Work Area, knew the risk factors for pregnancy, could read and write, and was willing to be respondents. Data analysis using the Kruskall Wallis test. Data collection uses a modified ZSAS questionnaire. Statistical test results p value (0,000) <α = (0.05) then Ho is rejected, which means there is a difference between the Anxiety Levels of Trimester III Pregnancy based on Pregnancy Risk Factors in Gribig Puskesmas Work Area in Kedungkandang District, Malang. The majority of respondents who belong to the low risk group (88.9%) experienced mild anxiety levels, the high risk group (86.7%) experienced moderate anxiety levels, and the very high risk group (66.7%) experienced severe anxiety levels. From the results of the study, showed that the higher the risk factors experienced the higher the level of anxiety. It is hoped that midwives can provide IEC about the screening results of pregnancy risk factor groups, and increase the attention and empathy of pregnant women who really need more information about pregnancy in order to overcome the anxiety that occurs.

Aim. Despite the fact that ischemic-cervical insufficiency (ICI) is considered to be a risk factor for preterm birth (PB), a comparative analysis of the risk factors for each complication of gestation (ICI and PB) showed considerable differences. This was the reason for conducting a study to identify the most significant risk factors for PB and ICI. Materials and Methods. A questionnaire survey of 267 pregnant women was carried out to study the anamnestic risk factors for PR and for assessment of the course and outcomes of the current pregnancy. The existence of statistically significant differences was determined using Fishers exact test, and the ranking of risk factors was performed by the value of x2 criterion, adjusted for likelihood. Results. Pregnancy ended prematurely in 14 women (5.2%). Extremely early PB made 14.3% among all PB, premature births – 21.4%, late births – 64.3%, early PB were absent. Spontaneous and induced PB occurred with the same frequency – 50% each in the PB structure. Based on the x2 calculation, a rating of the PB risk factors was made. The 1st place – history of induced PB, 2 – history of polycystic ovary syndrome; 3 – in vitro fertilization; 4 – arterial hypertension; 5 – asymptomatic bacteriuria; 6 – ICI; 7 – hypothyroidism; 8 – the premature birth of the father. Also, an assessment of the risk factors for ICI was carried out and their rating was compiled: 1 – intra-uterine interventions before the first birth; 2 – repeated intrauterine interventions; 3 – history of ICI. Conclusion. Women with endocrine disorders (thyroid disease, polycystic ovary syndrome), arterial hypertension before and during pregnancy, physical inactivity before pregnancy should be considered a high risk group for PB. Asymptomatic bacteriuria is a risk factor not only for PB, but also for ICI, in which connection its early detection and rehabilitation is advisable. In the course of our study, the necessity for cervicometry during the 1st ultrasound screening was confirmed, and dynamic cervicometry can be recommended not only for women with PB, late spontaneous miscarriages, history of ICI and ICI in the current pregnancy, but also for pregnant women with repeated intrauterine interventions and with intrauterine interventions before the first forthcoming birth, for the earlier detection of ICI and formation of a high-risk group for PR for arrangement of preventive measures.

AbstractCardiovascular diseases (CVDs) are the number one cause of death globally, and the early identification of high risk is crucial to prevent the disease and to reduce healthcare costs. Short life expectancy and increased mortality among the Roma are generally accepted (although not indeed proven by mortality analyses) which can be partially explained by the high prevalence of cardiovascular risk factors (CVRF) among them. This study aims to elaborate on the prevalence of the most important CVD risk factors, assess the estimation of a 10-year risk of development of fatal and nonfatal CVDs based on the most used risk assessment scoring models, and to compare the Hungarian general (HG) and Roma (HR) populations. In 2018 a complex health survey was accomplished on the HG (n = 380) and HR (n = 347) populations. The prevalence of CVRS was defined and 10-year cardiovascular risk was estimated for both study populations using the following systems: Framingham Risk Score for hard coronary heart disease (FRSCHD) and for cardiovascular disease (FRSCVD), Systematic COronary Risk Evaluation (SCORE), ACC/AHA Pooled Cohort Equations (PCE) and Revised Pooled Cohort Equations (RPCE). After the risk scores had been calculated, the populations were divided into risk categories and all subjects were classified. For all CVD risk estimation scores, the average of the estimated risk was higher among Roma compared to the HG independently of the gender. The proportion of high-risk group in the Hungarian Roma males population was on average 1.5–3 times higher than in the general one. Among Roma females, the average risk value was higher than in the HG one. The proportion of high-risk group in the Hungarian Roma females population was on average 2–3 times higher compared to the distribution of females in the general population. Our results show that both genders in the Hungarian Roma population have a significantly higher risk for a 10-year development of cardiovascular diseases and dying from them compared to the HG one. Therefore, cardiovascular interventions should be focusing not only on reducing smoking among Roma but on improving health literacy and service provision regarding prevention, early recognition, and treatment of lipid disorders and diabetes among them.

Purpose Patients with metastatic rhabdomyosarcoma (RMS), except those younger than 10 years with embryonal RMS, have an estimated long-term event-free survival (EFS) of less than 20%. The main goal of this study was to improve outcome of patients with metastatic RMS by dose intensification with interval compression, use of the most active agents determined in phase II window studies, and use of irinotecan as a radiation sensitizer. Patients and Methods Patients with metastatic RMS received 54 weeks of therapy: blocks of therapy with vincristine/irinotecan (weeks 1 to 6, 20 to 25, and 47 to 52), interval compression with vincristine/doxorubicin/cyclophosphamide alternating with etoposide/ifosfamide (weeks 7 to 19 and 26 to 34), and vincristine/dactinomycin/cyclophosphamide (weeks 38 to 46). Radiation therapy occurred at weeks 20 to 25 (primary) but was also permitted at weeks 1 to 6 (for intracranial or paraspinal extension) and weeks 47 to 52 (for extensive metastatic sites). Results One hundred nine eligible patients were enrolled, with a median follow-up of surviving patients of 3.8 years (3-year EFS for all patients, 38% [95% CI, 29% to 48%]; survival, 56% [95% CI, 46% to 66%]). Patients with one or no Oberlin risk factor (age > 10 years or < 1 year, unfavorable primary site of disease, ≥ three metastatic sites, and bone or bone marrow involvement) had a 3-year EFS of 69% (95% CI, 52% to 82%); high-risk patients with two or more risk factors had a 3-year EFS of 20% (95% CI, 11% to 30%). Toxicity was similar to that on prior RMS studies. Conclusion Patients with metastatic RMS with one or no Oberlin risk factor had an improved 3-year EFS of 69% on ARST0431 compared with an historical cohort from pooled European and US studies; those with two or more risk factors have a dismal prognosis, and new approaches are needed for this very-high-risk group.

Abstract Objective: To establish a predictive model of carotid vulnerable plaque through systematic screening of high-risk population for stroke.Patients and methods: All community residents who participated in the screening of stroke high-risk population by the China National Stroke Screening and Prevention Project (CNSSPP). A total of 19 risk factors were analyzed. Individuals were randomly divided into Derivation Set group and Validation Set group. According to carotid ultrasonography, the derivation set group patients were divided into instability plaque group and non-instability plaque group. Univariate and multivariable logistic regression were taken for risk factors. A predictive model scoring system were established by the coefficient. The AUC value of both derivation and validation set group were used to verify the effectiveness of the model.Results: A total of 2841 high-risk stroke patients were enrolled in this study, 266 (9.4%) patients were found instability plaque. According to the results of Doppler ultrasound, Derivation Set group were divided into instability plaque group (174 cases) and non-instability plaque group (1720 cases). The independent risk factors for carotid instability plaque were: male (OR 1.966, 95%CI 1.406-2.749)，older age (50-59, OR 6.012, 95%CI 1.410-25.629; 60-69, OR 13.915, 95%CI 3.381-57.267;≥70, OR 31.267, 95%CI 7.472-130.83) , married(OR 1.780, 95%CI 1.186-2.672)，LDL-c(OR 2.015, 95%CI 1.443-2.814), and HDL-C(OR 2.130, 95%CI 1.360-3.338). A predictive scoring system was created, range 0-10. The cut-off value of prediction model score is 6.5. The AUC value of derivation and validation set group were 0.738 and 0.737.Conclusion：For a high risk group of stroke individual, We provide a model that could distinguishing those who have a high probability of having carotid instability plaque. When resident’s predictive model score exceeds 6.5, the incidence of carotid instability plaque is high, carotid artery Doppler ultrasound would be checked immediately. This model can be helpful in the primary prevention of stroke.

Objective Search of pathogenetic mechanisms and risk factors of atherosclerosis in the employees of the cleaning service in Tbilisi. Materials and Methods As a result of a preliminary survey and examination of 200 employes of Tbilisi cleaning service aged 25-45 years (2014-2016), 22 patients with angina, hypercholesterolemia, intimae-media thickness > 0.65 mm, were selected into I group, and 23 individuals without these disorders into II group. In the blood plasma of the selected patients the intensity of oxidative metabolism parameters, TAA and MDA were determined. The variance and correlation analysis (АNOVA) was used for conducting the comparative analysis of the levels of studied parameters. Results In the combined group (I+II) there are several reliable correlations between the Age -TCol, Age-MDA, BMI-Tg, BMI-MDA, LDLChol-HDLChol, LDLChol–TChol, HDLChol-TChol, LDLChol-MDA, LDLChol-TAA. no correlation between these parameters in individual groups (I and II) was found. That indicates that we have an imaginary correlation related to the large intergroup difference between the average values of the group indicators, that is the values of various indicators change during the development of the pathological process, but there is no causal relationship between these alterations. The reliable TAA-MDA correlation in the combined group (I+II) is related to the high anticorrelation between these parameters and the significantly higher average value of TAA in the low-risk group (II) in comparison to the high-risk group (I). Conclusion The results analysis indicates both the diagnostic value of redox status indicators and their leading role in the atherogenesis processes. In populations with a high risk of atherosclerosis, monitoring of serum TAA is recommended.

The Impact

Background: Despite steady improvements in cardiac surgery-related outcomes, our understanding of the physiologic mechanisms leading to perioperative mortality remains incomplete. Intraoperative hypotension is an important risk factor for mortality after noncardiac surgery but remains relatively unexplored in the context of cardiac surgery. We examined whether the association between intraoperative hypotension and in-hospital mortality varied by patient and procedure characteristics, as defined by the validated Cardiac Anesthesia Risk Evaluation (CARE) mortality risk score. Methods: We conducted a retrospective cohort study of consecutive adult patients who underwent cardiac surgery requiring cardiopulmonary bypass (CPB) from November 2009–March 2015. Those who underwent off-pump, thoracic aorta, transplant and ventricular assist device procedures were excluded. The primary outcome was in-hospital mortality. Hypotension was categorized by mean arterial pressure (MAP) of <55 and between 55–64 mmHg before, during and after CPB. The relationship between hypotension and death was modeled using multivariable logistic regression in the intermediate and high-risk groups. Results: Among 6627 included patients, 131 (2%) died in-hospital. In-hospital mortality in patients with CARE scores of 1, 2, 3, 4 and 5 was 0 (0%), 7 (0.3%), 35 (1.3%), 41 (4.6%) and 48 (13.6%), respectively. In the intermediate-risk group (CARE = 3–4), MAP < 65 mmHg post-CPB was associated with increased odds of death in a dose-dependent fashion (adjusted OR 1.30, 95% CI 1.13–1.49, per 10 min exposure to MAP < 55 mmHg, p = 0.002; adjusted OR 1.18 [1.07–1.30] per 10 min exposure to MAP 55–64 mmHg, p = 0.001). We did not observe an association between hypotension and mortality in the high-risk group (CARE = 5). Conclusions: Post-CPB hypotension is a potentially modifiable risk factor for mortality in intermediate-risk patients. Our findings provide impetus for clinical trials to determine if hemodynamic goal-directed therapies could improve survival in these patients.

Abstract In the German Multicenter ALL studies (GMALL) patients aged &gt;55 years with high risk (B-lineage ALL with WBC at diagnosis &gt;30000, late CR, t (4; 11), complex aberrant karyotype or prae-T or mature T-ALL) or very high risk (Ph+/BCR-ABL+) ALL are increasingly candidates for allogeneic stem cell transplantation (allogeneic SCT with a HLA identical sibling donor, MRD or a matched unrelated donor, MUD) or autologous SCT. Here, we report on 31 elderly patients transplanted within the GMALL studies 06/99 and 07/03. Median age of the patients was 61 years (56–65). 22 patients belonged to the very high risk group (VHR), 8 patients to the high risk group (HR) and 1 patient from the standard risk group (SR) was transplanted because of detection of minimal residual disease.17/31 patients were transplanted from a matched unrelated donor, 9/31 patients from a HLA identical sibling donor and 5/31 patients underwent autologous SCT. Conditioning regimens for MRD SCT were myeloablative (MAC) in 6 patients (TBI 12 Gy and chemotherapy n=2, radioimmunotherapy + chemotherapy n=2, chemotherapy only n=2) and 3 patients received reduced intensity conditioning (RIC).Conditioning regimens for MUD SCT changed over time with an increasing number of RIC in the study 07/03. In total, 7/17 patients received MAC (TBI 12 Gy and chemotherapy n=5, chemotherapy only n=2) and 10/17 patients received RIC. Conditioning regimens in autologous SCT were myeloablative (MAC) in 5/5 patients. Results: After allogeneic MRD SCT 4/9 patients (44%) are alive in CCR (d+ 24, d+ 611, d+ 1721, d+ 2321), 3/9 patients died due to leukemia, 2/9 due to transplant related mortality (TRM). After allogeneic MUD SCT 8/17 patients (46%) are alive in CCR (from d+ 165 to d+ 2176). 1 further patient is alive after re- SCT for treatment of relapse. 7/17 patients died due to TRM and 1 patient died due to relapse. After autologous SCT 2/5 patients are alive in CCR (d+ 1703, d+ 1731), 3/5 died due to relapse. Risk factors for TRM: In allo SCT and MAC 8/13 patients died due to TRM in contrast to 1/13 patients with RIC. In auto SCT none of the patients died due to TRM. Risk factors for relapse: In allogeneic MRD SCT 3/9 patients died due to relapse and 2/17 patients relapsed after MUD SCT. Due to the small number of patients, no difference between MAC and RIC could be found. In autologous SCT 3/5 patients died due to relapse. In conclusion: The study shows that allo MRD but also MUD SCT is very effective in a selected population of elderly ALL patients. Since the survival of elderly patients with chemotherapy only is about 25%, more patients should be encouraged to have a MRD or MUD SCT.

10032 Background: We recently reported the results in C & A with low risk (group A), intermediate risk (group B) and high risk (group C) mature B-NHL treated on FAB/LMB 96 (Gerrard et al, Br J Haematol, 2008; Patte et al, Blood, 2007; Cairo et al, Blood, 2007, respectively). Adolescent age (15–21 yrs) has historically been considered to be an independent risk factor for poor outcome in subsets of mature B-NHL (Hochberg/Cairo et al, Br J Haematol, 2008; Burkhardt et al, Br J Haematol 2005; Cairo et al, Br J Haematol, 2003). Methods: We analyzed the EFS of all pts treated on FAB/LMB 96 and the following risk factors were significant in a univariate and Cox multivariate analysis: age (<15 vs ≥15 yrs), stage I/II vs III/IV, primary sites, LDH <2 vs ≥2 NL and histology (DLBCL vs BL/BLL). Results: 1111 pts (15%, 15–21 years) were treated with group A (N = 132), group B (N = 744), and group C (N = 235) therapy. Five year EFS (CI95) for all, A, B, C pts was 86% (84%,88%), 98% (93%, 100%), 87%% (84%, 89%), and 79%% (73%,84%), respectively. Age (≥15 yrs), LDH ≥2NL, stage III/IV, and BM+/CNS+ and histology were significant univariate risk factors for decreased EFS (P<0.045, <0.0001, <0.0001, <0.0001, and <0.0001 respectively). Multivariate analysis demonstrated age ≥15 yrs and DLBCL histology were no longer independent significant risk factors (p = .82 and 0.08, respectively), but LDH (RR 2.0, p = .001), stage III/IV (RR 3.8, p<0.001), and primary sites including PMBL (RR 4.0, p<.001) and BM+/CNS+ (RR 2.8, p<0.001) were independent significant risk factors for poorer outcome. Conclusions: With the use of modern short but intense FAB-LMB 96 therapy, adolescent age is no longer a poor risk factor in children with mature B-NHL. The independent risk factors identified in this study (stage, LDH, primary site) for decreased EFS in C & A mature B-NHL will form the basis of the next risk adapted international pediatric mature B-NHL trial.
