ObjectiveTo examine the association between sleep quality and military training injury (MTI) in recruits during basic combat training (BCT).MethodsParticipants were new recruits undergoing 12-week military BCT in China. Sleep quality was measured by the Pittsburgh Sleep Quality Index (PSQI) . Participants were classified into two groups based on their sleep quality (group 1, good sleep, PSQI score <7; group 2, poor sleep, PSQI score ≥7) at the start of BCT. Logistic regression analysis was conducted to test whether baseline PSQI score was associated with MTI incidence during BCT.ResultsA total of 563 participants were included. The incidence of MTI was significantly lower in group 1 (48/203, 23.6%) than in group 2 (150/360, 41.7%) (p<0.001). Logistic regression analysis showed that the odds of MTI were 2.307 times higher in group 2 than in group 1 without adjusting for confounders: OR=2.307, p<0.001. When the model was adjusted for age, ethnicity, educational level and family income (OR=2.285) or for the previous confounders plus body mass index (OR=2.377), the results were similar (both p<0.001). Analysis of the types of initial MTI showed that group 2 had about 2.1 times higher odds of soft tissue injury than group 1 (p<0.001 in all the three models).ConclusionSleep quality before BCT influences the incidence of MTI, especially of soft tissue injury.

Background: It has been still unclear whether the cut-off value of the short physical performance battery for predicting the ability of the toilet activity in the hospitalized older patients. The aim of this study was to reveal the relationship between the short physical performance battery and the ability of toilet activity, and also to determine the cut-off value of the short physical performance battery score for the ability of toilet activity in the hospitalized older patients. Methods: In this cross-sectional study, 71 hospitalized older patients were recruited. The short physical performance battery and the ability of toilet activity using the Barthel index (BI) were measured. The patients were split into two groups, according to the ability of toilet activity (Group 1: 10 point; Group 2: 5 point or less in BI score). A multiple logistic regression analysis was used to assess the relationship between the two groups. Moreover, the cut-off value for dividing into two groups, (Group 1 and Group 2) using the short physical performance battery score, which was calculated by a receiver operating characteristic curve. Results: The short physical performance battery score was an independent explanator for the ability of toilet activity using multiple logistic regression analysis. Besides, the cut-off value of the short physical performance battery for the ability of toilet activity was set in this study. Conclusion: The findings of this study suggest that the cut-off value of the short physical performance battery score could be a useful index to predict the ability of toilet activity in the hospitalized older patients.

Objective: Predicting postoperative atrial fibrillation (PoAF) in the preoperative period will provide a serious advantage in preventing the morbidity and mortality associated with this arrhythmia and in planning the treatment. In this study, we investigated the value of atrial electromechanical delay (AEMD) in predicting the development of PoAF. Methods: A total of 93 patients who underwent isolated coronary artery bypass grafting (CABG) operation were included in this prospective study. Patients’ demographic characteristics, laboratory parameters, echocardiographic data, and AEMD durations that could be measured by the co-use of electrocardiography and echocardiography were recorded. The patients at sinus rhythm during the postoperative period were identified as “Group 1”, and those who developed PoAF were identified as “Group 2”. Results: PoAF incidence was 26.88% (n=25). Left ventricle (LV) lateral AEMD, LV medial AEMD, right ventricle lateral AEMD, and left atrium (LA) lateral AEMD durations of Group 2 were significantly higher than Group 1 (p<0.001, p=0.004, p=0.004, p<0.001; respectively). In Univariate Logistic Regression Analysis, the age, hypertension, LA maximum volume, LA lateral AEMD and pulmonary artery pressure were significantly associated with PoAF development (p=0.01, p=0.004, p=0.004, p=0.001, p=0.01; respectively). However, only LA lateral AEMD was found as an independent predictive factor for the development of PoAF in the Multivariate Logistic Regression Analysis (OR:1.03, 95% CI:1,001-1.06, p=0.04). AUC was 0.741 for LA lateral AEMD in ROC Curve Analysis (95% CI:0.633-0.849, p<0.001). Conclusions: The development of PoAF can be predicted by AEMD durations measured in the preoperative period in patients undergoing isolated CABG.

This study aimed to address the impact of 1-hr bundle achievement on outcomes in septic shock patients. Secondary analysis of multicenter prospectively collected data on septic shock patients who had undergone protocolized resuscitation bundle therapy at emergency departments was conducted. In-hospital mortality according to 1-h bundle achievement was compared using multivariable logistic regression analysis. Patients were also divided into 3 groups according to the time of bundle achievement and outcomes were compared to examine the difference in outcome for each group over time: group 1 (≤1 h reference), group 2 (1–3 h) and group 3 (3–6 h). In total, 1612 patients with septic shock were included. The 1-h bundle was achieved in 461 (28.6%) patients. The group that achieved the 1-h bundle did not show a significant difference in in-hospital mortality compared to the group that did not achieve the 1-h bundle on multivariable logistic regression analysis (<1 vs. >1 h) (odds ratio = 0.74, p = 0.091). However, 3- and 6- h bundle achievements showed significantly lower odds ratios of in-hospital mortality compared to the group that did not achieve the bundle (<3 vs. >3 h, <6 vs. >6 h, odds ratio = 0.604 and 0.458, respectively). There was no significant difference in in-hospital mortality over time for group 2 and 3 compared to that of group 1. One-hour bundle achievement was not associated with improved outcomes in septic shock patients. These data suggest that further investigation into the clinical implications of 1-h bundle achievement in patients with septic shock is warranted.

Aim: The aim of this study was to investigate whether there is a relationship between erectile dysfunction (ED), thought to be a vascular disease, and AB0 blood group. Material and Method: The study included 350 people abiding by the study criteria who applied to our clinic from April 2012-April 2015. The patients were divided into two groups including those with ED (Group 1) and those without (Group 2). Age, blood group, IIEF-5 score and presence of additional diseases were recorded. Erectile functions were analyzed according to blood group. Results: There was no difference between the mean age of 111 patients with ED and that of 239 patients without ED included in the study (p = 0.284). There was no difference between patients in the two groups in terms of smoking, alcohol use, hypertension and diabetes (p &gt; 0.05). Among patients in the ED group, the mean IIEF-5 score according to blood group was 19.8 ± 5.04 in the 0 blood group, 16.5 ± 5.2 in the A blood group, 17.2 ± 5.3 in the B blood group and 13.3 ± 3.02 in the AB blood group. The IIEF-5 scores of individuals in the 0 blood group were significantly high compared to individuals in other blood groups (p = 0.004). Logistic regression analysis found that compared to the 0 blood group, the erectile dysfunction risk was 3.9 times greater for the A blood group, 3.5 times greater for the B blood group and 4.7 times greater for the AB blood group (p = 0.001) (Table 3). Conclusion: The risk of erectile dysfunction was significantly increased for individuals in the A, B and AB blood groups compared to individuals in the 0 blood group.

177 Background: PSA produced from prostate cancer (PC) cells escapes proteolytic processing, resulting in a more complexed PSA and a lower %fPSA. Higher %fpsa correlates with lower PC risk. However, the role of fPSA in biochemical recurrence (BCR) after radical prostatectomy (RP) is unknown. Methods: All patients who had BCR after RP and at least one fPSA test, were included. Patients were stratified according to the %fPSA cut-off of 0.15. Multivariable logistic regression analysis was performed to predict covariates associated with a higher %fPSA. Results: A total of 81 men with BCR were found (Table 1). Interestingly, 20% (group 1) vs. 60% (groups 2) become castrate resistant (CRPC), p<0.0001 and the time to reach CRPC state was much shorter in group 2 (33.5 months) vs. group 1 (57.9 months), p=0.05. Additionally, 60% of group 2 patients vs. 32.5% of group 1 patients developed metastasis, p=0.014. Lastly, median survival of 193 months for group 2 patients with no median survival for group 1, Log Rank test p=0.023. Multivariable logistic regression analysis demonstrated that secondary Gleason score of 5 (compared to 3) and %fPSA>0.15 predicted CRPC status (OR 11.63, CI 95% 1.38-97.4, p=0.024, OR 7.99, CI 95% 2-31.95, p=0.003, respectively). Conclusions: %fPSA>0.15 in the setting of BCR confers a more aggressive disease, manifesting in a faster development of CRPC, metastasis and death. Our findings suggest a reversal in the significance of % fPSA values in BCR patients, and should be validated in larger cohorts. [Table: see text]

AbstractTo determine if delaying the primary precutaneous coronary intervention (PCI) for >6 hours for acute coronary syndrome with preserved ST elevation (STE-ACS) affects the PCI angiography effectiveness and clinical prognosis. The PCI was performed: for 71% of patients <6h (group 1), for 29% of patients >6h from the beginning of pain (group 2). For 1% of patients from group 1 and 3.4% of patients from group 2, no passage has been opened in the artery after STE-ACS. In spite of opening the passage mechanically, the phenomenon of lack of tissue reflow occurred in 2.7% of patients from group 1 and 12% of patients from group 2. Dangerous ventricular arrhythmias occurred more frequently in patients from group 2, including VF, asystole, haemodynamic complications classed 4° according to the Killip-Kimball scale and death. In an univariate logistic regression analysis, the following risk factors for death during the hospital phase were identified: delayed PCI >6 hours, 4° haemodynamic complications according to the Killip-Kimball scale, LVEF <40%, FV, p-k III block, TIMI <3, and no-reflow. In a multivariate logistic regression analysis, 4° according to the Killip-Kimball scale turned out to be the only risk factor for death during the hospital phase. Delaying PCI during STE-ACS for >6 hours significantly lowers the statistical chance to recover both full permeability and effective tissue reflow in the artery responsible for STE-ACS, which is connected with a significantly higher risk of serious complications, as well as with 8.5% risk of death during the hospital phase. The most significant, independent factor determining the survival of patients with STE-ACS after PCI is lack of cardiogenic shock.

Objectives: Hip labral reconstruction has been reported with short-term improvement in patient-reported outcomes and functional scores postoperatively; however, its mid-term outcomes and the risk factors of total hip replacement (THR) conversion are still unclear. The purpose of this study was to evaluate the results of patients who underwent labral reconstruction with iliotibial band autograft comparing our first 100 patients to the last 100 patients. We hypothesized that patient selection had been changed between the 2 cohorts and the last 100 patients achieved better clinical outcomes than the first 100 patients. Methods: The Skeletally mature patients (>17 years) who underwent hip labral reconstruction with autologous iliotibial band were evaluated preoperatively and postoperatively with a minimum 2 years follow-up. The first consecutive 100 patients (Group 1, between September 2005 and December 2008) and the last 100 patients (Group 2, between August 2011 and October 2014) were retrospectively compared. Radiographic evaluations were performed preoperatively. Conversion ratio to THR, necessity of a revision hip arthroscopy, and 7 kinds of outcome scores were evaluated postoperatively. Student t-test, chi-square test were used to compare 2 groups. Logistic regression analysis and receiver operating characteristic (ROC) curve analysis were performed to detect the risk factors of THR conversion. Results: Overall follow-up rate (> 2 years) was 94% (Group 1 v Group 2, 96% v 91%, P = 0.25). The follow-up period of Group 1 was significantly longer (year, 4.8 v 2.8, P < 0.001). Mean age of Group 1 was significantly higher than that of Group 2 (year, 37.1 v 33.5, P = 0.032). In Group 2, 69 surgeries out of 100 were revision hip arthroscopies, which was significantly higher rate than Group 1 (48%, P = 0.003). Group 1 had significantly higher rate of THR conversion (23% v 5%, P = 0.001). Revision hip arthroscopy was performed 11% of Group 1 and 9% of Group 2 (P = 0.751) (Table). Clinical outcomes of the patients who did not require further surgery were similar between 2 groups (all P > 0.15, Figure). In logistic regression analysis, only higher age was significant risk factor of THR conversion, while grouping, primary surgery were not significant (age: P < 0.001, odds ratio 1.15 [95%, 1.08 -1.22], Group 1: P = 0.09, primary surgery: P = 0.06). Cut off value of age calculated by ROC curve was 45.5 years, and 47% of the overall patients older than 46 years had THR after surgery (5% in the patients younger than 45 years, P < 0.001). The rate of the patients older than 46 years in Group 1 was significantly higher than that in Group 2 (30% v 17%, P = 0.030). Conclusion: Patient selection had been changed between the first 100 and the last 100 cohorts. Higher age, especially older 46 year-old, was significantly associated with higher conversion rate to THR. Although autologous labral reconstruction was a promising procedure with success rate of up to 80% in this mid-term investigation, patient selection was considered to be the key to increase the survivorship.

ABSTRACT:Background:Post-cardiac surgery patients exhibit a higher incidence of postoperative delirium (PD) compared to non-cardiac surgery patients. Patients with various cardiac diseases suffer from preoperative sleep disorder (SPD) induced by anxiety, depression, breathing disorder, or other factors.Objective:To examine the effect of sleep disorder on delirium in post-cardiac surgery patients.Methods:We prospectively selected 186 patients undergoing selective cardiac valve surgery. Preoperative sleep quality and cognitive function of all eligible participants were assessed through the Pittsburgh Sleep Quality Index (PSQI) and the Montreal Cognitive Assessment, respectively. The Confusion Assessment Method for Intensive Care Unit was used to assess PD from the first to seventh day postoperatively. Patients were divided into two groups according to the PD diagnosis: (1) No PD group and (2) the PD group.Results:Of 186 eligible patients, 29 (15.6%) were diagnosed with PD. A univariate analysis showed that gender (p = 0.040), age (p = 0.009), SPD (p = 0.008), intraoperative infusion volume (p = 0.034), postoperative intubation time (p = 0.001), and intensive care unit stay time (p = 0.009) were associated with PD. A multivariate logistic regression analysis demonstrated that age (odds ratio (OR): 1.106; p = 0.001) and SPD (OR: 3.223; p = 0.047) were independently associated with PD. A receiver operating characteristic curve demonstrated that preoperative PSQI was predictive of PD (area under curve: 0.706; 95% confidence interval: 0.595–0.816). A binomial logistic regression analysis showed that there was a significant association between preoperative 6 and 21 PSQI scores and PD incidence (p = 0.009).Conclusions:Preoperative SPD was significantly associated with PD and a main predictor of PD.

Aims Guided growth has been used to treat coxa valga for cerebral palsy (CP) children. However, there has been no study on the optimal position of screw application. In this paper we have investigated the influence of screw position on the outcomes of guided growth. Methods We retrospectively analyzed 61 hips in 32 CP children who underwent proximal femoral hemi epiphysiodesis between July 2012 and September 2017. The hips were divided into two groups according to the transphyseal position of the screw in the coronal plane: across medial quarter (Group 1) or middle quarter (Group 2) of the medial half of the physis. We compared pre- and postoperative radiographs in head-shaft angle (HSA), Reimer’s migration percentage (MP), acetabular index (AI), and femoral anteversion angle (FAVA), as well as incidences of the physis growing-off the screw within two years. Linear and Cox regression analysis were conducted to identify factors related to HSA correction and risk of the physis growing-off the screw. Results A total of 37 hips in Group 1 and 24 hips in Group 2 were compared. Group 1 showed a more substantial decrease in the HSA (p = 0.003) and the MP (p = 0.032). Both groups had significant and similar improvements in the AI (p = 0.809) and the FAVA (p = 0.304). Group 1 presented a higher incidence of the physis growing-off the screw (p = 0.038). Results of the regression analysis indicated that the eccentricity of screw position correlated with HSA correction and increases the risk of the physis growing-off the screw. Conclusion Guided growth is effective in improving coxa valga and excessive femoral anteversion in CP children. For younger children, despite compromised efficacy of varus correction, we recommend a more centered screw position, at least across the middle quarter of the medial physis, to avoid early revision.

Introduction: We sought to design a partial nephrectomy (PN) with contralateral total nephrectomy porcine model and assess the underlying mechanisms of ischemia reperfusion injury (IRI) after PN using a novel, clinically approved resection device.Methods: Domestic male pigs (n=9) underwent left lower pole PN, allocated to either standard (Group 1) or no ischemia PN (Group 2), followed by contralateral nephrectomy. Biochemical studies were performed at baseline, Day 2, and Day 7; after sacrifice, kidneys were processed for histological analysis. Apoptotic markers were measured by Western blot analyses. Urinary biomarkers were measured to assess acute kidney injury.Results: At Day 2 following PN, there was a significant rise in serum creatinine in Group 1 compared to Group 2 (355 vs. 136 mmol/L; p=0.008). Intra-renal tissue oxygen saturation after PN was inversely correlated with postoperative creatinine (rs -0.75; p=0.012) and the grade of acute tubular necrosis (rs -0.70; p=0.036). We observed a rise in expression of pro-apoptotic markers and pro-inflammatory markers in Group 1 following PN compared to Group 2. Histological analysis revealed higher grade of apoptosis in Group 1.Conclusions: IRI associated with standard PN has a deleterious impact on acute renal function, markers of tissue injury, and histological parameters, compared to off-clamp PN using the ALTRUS device. We identified several intraoperative and postoperative markers that may be used as predictors for functional and histological injury following PN.
