To assess whether a strategy of endovascular repair (if aortic morphology is suitable, open repair if not) versus open repair reduces early mortality for patients with suspected ruptured abdominal aortic aneurysm. Randomised controlled trial. 30 vascular centres (29 UK, 1 Canadian), 2009-13. 613 eligible patients (480 men) with a clinical diagnosis of ruptured aneurysm. 316 patients were randomised to the endovascular strategy (275 confirmed ruptures, 174 anatomically suitable for endovascular repair) and 297 to open repair (261 confirmed ruptures). 30 day mortality, with 24 hour and in-hospital mortality, costs, and time and place of discharge as secondary outcomes. 30 day mortality was 35.4% (112/316) in the endovascular strategy group and 37.4% (111/297) in the open repair group: odds ratio 0.92 (95% confidence interval 0.66 to 1.28; P=0.62); odds ratio after adjustment for age, sex, and Hardman index 0.94 (0.67 to 1.33). Women may benefit more than men (interaction test P=0.02) from the endovascular strategy: odds ratio 0.44 (0.22 to 0.91) versus 1.18 (0.80 to 1.75). 30 day mortality for patients with confirmed rupture was 36.4% (100/275) in the endovascular strategy group and 40.6% (106/261) in the open repair group (P=0.31). More patients in the endovascular strategy than in the open repair group were discharged directly to home (189/201 (94%) v 141/183 (77%); P<0.001). Average 30 day costs were similar between the randomised groups, with an incremental cost saving for the endovascular strategy versus open repair of £1186 (€1420; $1939) (95% confidence interval -£625 to £2997). A strategy of endovascular repair was not associated with significant reduction in either 30 day mortality or cost. Longer term cost effectiveness evaluations are needed to assess the full effects of the endovascular strategy in both men and women. Current Controlled Trials ISRCTN48334791.

Open versus laparoscopic appendectomy.

PubMed

Herman, J; Duda, M; Lovecek, M; Svach, I

2003-01-01

To asses the role of laparoscopic appendectomy in the treatment of acute as well as chronic appendicitis on the basis of our own experiences. From the set of 849 patients treated with appendectomy (from January 1993 to December 2000) 331 were singled out, i.e.; those unable to work for some time and thus being on sickness benefit who asked for a medical certificate. They were operated on for either acute or chronic appendicitis. In our set of 331 patients (158 males, 173 females, the average age 29.4) open appendectomy was performed on 179 patients and laparoscopic appendectomy on 152. Laparoscopic appendectomy was performed in 43 males (28%) and 109 females (72%); open appendectomy in 115 males (64%) and 64 females (36%). Laparoscopic appendectomy took 53.7 +/- 18.1 minutes, open appendectomy took 43.6 +/- 8.99 minutes. The time of work disablement is longer in open appendectomy (open appendectomy: 41.2 +/- 9.91 days; laparoscopic appendectomy; 29.1 +/- 15.11 days). A significant difference (p < 0.00001) can be seen in the length of hospitalization (laparoscopic appendectomy: 5.0 +/- 2.75 days, open appendectomy: 8.3 +/- 2.83 days). Patients who undergo laparoscopic appendectomy spent less time in hospital, and they can return to work rather earlier. On the other hand the time of surgery is longer. Higher cost is compensated for with shorter hospitalization and early return to work.

Health resource use after robot-assisted surgery vs open and conventional laparoscopic techniques in oncology: analysis of English secondary care data for radical prostatectomy and partial nephrectomy.

To evaluate postoperative health resource utilisation and secondary care costs for radical prostatectomy and partial nephrectomy in National Health Service (NHS) hospitals in England, via a comparison of robot-assisted, conventional laparoscopic and open surgical approaches. We retrospectively analysed the secondary care records of 23 735 patients who underwent robot-assisted (RARP, n = 8 016), laparoscopic (LRP, n = 6 776) or open radical prostatectomy (ORP, n = 8 943). We further analysed 2 173 patients who underwent robot-assisted (RAPN, n = 365), laparoscopic (LPN, n = 792) or open partial nephrectomy (OPN, n = 1 016). Postoperative inpatient admissions, hospital bed-days, excess bed-days and outpatient appointments at 360 and 1 080 days after surgery were reviewed. Patients in the RARP group required significantly fewer inpatient admissions, hospital bed-days and excess bed-days at 360 and 1 080 days than patients undergoing ORP. Patients undergoing ORP had a significantly higher number of outpatient appointments at 1 080 days. The corresponding total costs were significantly lower for patients in the RARP group at 360 days (£1679 vs £2031 for ORP; P < 0.001) and at 1 080 days (£3461 vs £4208 for ORP; P < 0.001). In partial nephrectomy, Patients in the RAPN group required significantly fewer inpatient admissions and hospital bed-days at 360 days compared with those in the OPN group; no significant differences were observed in outcomes at 1 080 days. The corresponding total costs were lower for patients in the RAPN group at 360 days (£779 vs £1242 for OPN, P = 0.843) and at 1 080 days (£2122 vs £2889 for ORP; P = 0.570). For both procedure types, resource utilisation and costs for laparoscopic surgeries lay at the approximate midpoint of those for robot-assisted and open surgeries. Our analysis provides compelling evidence to suggest that RARP leads to reduced long-term health resource utilisation and downstream cost savings compared with traditional open and laparoscopic approaches. Furthermore, despite the limitations that arise from the inclusion of a small sample, these results also suggest that robot-assisted surgery may represent a cost-saving alternative to existing surgical options in partial nephrectomy. Further exploration of clinical cost drivers, as well as an extension of the analysis into subsequent years, could lend support to the wider commissioning of robot-assisted surgery within the NHS. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

Tonsillectomy in children and in adults: changes in practice following the opening of a day-surgery unit with dedicated operating room.

To study the impact of the opening of a day-surgery unit on the practice of tonsillectomy in adults and children in the light of the experience of our department, and to compare complications between day-surgery and conventional admission. A retrospective review was conducted of all tonsillectomies performed since the opening of a dedicated day-surgery room, using the ENT and emergency department data-bases. Between October 2013 and December 2014, 179 tonsillectomies were performed (51 in adults, 128 in children), including 108 day-surgeries. Between 2012 and 2014, the number of tonsillectomies increased by 12.7%, with an 18.27% increase in children and stable adult rate. Within 1 year, day-surgery became predominant for children (73.19%) and equaled conventional admission for adults (47.22%). For almost all patients without same-day discharge, the reasons were organizational or due to malorientation (comorbidity, or unsuitable home environment). Day-case tonsillectomy in children showed a 30-day complications rate comparable to those reported in the literature (8.3% postoperative hemorrhage), with a higher rate in adults (35.3%). Onset of complications was at a mean 6 days in adults and 9 days in children; only 2 patients developed complications between 6 and 24hours postoperatively. The present study showed that opening a day-surgery unit led to changes in practice, with most tonsillectomies now performed on an outpatient basis, without increased complications, and notably immediate complications. Outpatient tonsillectomy thus seems to be a solution of choice compared to conventional admission, in terms of cost saving and of patient comfort, without sacrificing safety. The dedicated operating room facilitates scheduling and thereby increasing turnover by reducing wait time. Copyright © 2018. Published by Elsevier Masson SAS.

The background of this paper is to report the mortality at 30 and 90 days and at mean follow-up after open abdominal aortic aneurysms (AAA) emergent repair and to identify predictive risk factors for 30- and 90-day mortality. Between 1997 and 2002, 104 patients underwent emergent AAA open surgery. Symptomatic and ruptured AAAs were observed, respectively, in 21 and 79% of cases. Mean patient age was 70 (SD 9.2) years. Mean aneurysm maximal diameter was 7.4 (SD 1.6) cm. Primary endpoints were 30- and 90-day mortality. Significant mortality-related risk factor identification was the secondary endpoint. Open repair trend and its related perioperative mortality with a per-year analysis and a correlation subanalysis to identify predictive mortality factor were performed. Mean follow-up time was 23 (SD 23) months. Overall, 30-day mortality was 30%. Significant mortality-related risk factors were the use of computed tomography (CT) as a preoperative diagnostic tool, AAA rupture, preoperative shock, intraoperative cardiopulmonary resuscitation (CPR), use of aortic balloon occlusion, intraoperative massive blood transfusion (MBT), and development of abdominal compartment syndrome (ACS). Previous abdominal surgery was identified as a protective risk factor. The mortality rate at 90 days was 44%. Significant mortality-related risk factors were AAA rupture, aortocaval fistula, peripheral artery disease (PAD), preoperative shock, CPR, MBT, and ACS. The mortality rate at follow-up was 45%. Correlation analysis showed that MBT, shock, and ACS are the most relevant predictive mortality factor at 30 and 90 days. During the transition period from open to endovascular repair, open repair mortality outcomes remained comparable with other contemporary data despite a selection bias for higher risk patients. MBT, shock, and ACS are the most pronounced predictive mortality risk factors.

Children with congenital heart disease (CHD) often require noncardiac surgery. We compared outcomes following open and laparoscopic intraabdominal surgery among children with and without CHD. We performed a retrospective cohort study using the 2013-2015 National Surgical Quality Improvement Project-Pediatrics. We matched 45,012 children <18years old who underwent laparoscopic surgery to 45,012 children who underwent open surgery. We determined the associations between laparoscopic (versus open) surgery and 30-day mortality, in-hospital mortality, 30-day morbidity, and postoperative length-of-stay. Among children with minor CHD, laparoscopic surgery was associated with lower 30-day mortality (Odds Ratio [OR] 0.34 [95% Confidence Interval 0.15-0.79]), inhospital mortality (OR 0.42 [0.22-0.81]) and 30-day morbidity (OR 0.61 [0.50-0.73]). As CHD severity increased, this benefit of laparoscopic surgery decreased for 30-day morbidity (ptrend=0.01) and in-hospital mortality (ptrend=0.05), but not for 30-day mortality (ptrend=0.27). Length-of-stay was shorter for laparoscopic approaches for children at cost of higher readmissions. On subgroup analysis, laparoscopy was associated with lower odds of postoperative blood transfusion in all children. Intraabdominal laparoscopic surgery compared to open surgery is associated with decreased morbidity in patients with no CHD and lower morbidity and mortality in patients with minor CHD, but not in those with more severe CHD.

2018-04-26

To compare the perioperative outcomes of initial, consecutive robotic-assisted transabdominal preperitoneal (R-TAPP) inguinal hernia repair (IHR) cases with consecutive open cases completed by the same surgeons. Multicenter, retrospective, comparative study of perioperative results from open and robotic IHR using standard univariate and multivariate regression analyses for propensity score matched (1:1) cohorts. Seven general surgeons at six institutions contributed 602 consecutive open IHR and 652 consecutive R-TAPP IHR cases. Baseline patient characteristics in the unmatched groups were similar with the exception of previous abdominal surgery and all baseline characteristics were comparable in the matched cohorts. In matched analyses, postoperative complications prior to discharge were comparable. However, from post discharge through 30 days, fewer patients experienced complications in the R-TAPP group than in the open group [4.3% vs 7.7% (p = 0.047)]. The R-TAPP group had no reoperations post discharge through 30 days of follow-up compared with five patients (1.1%) in the open group (p = 0.062), respectively. Multivariate logistic regression analysis which demonstrated patient age > 65 years and the open approach were risk factors for complications within 30 days post discharge in the matched group [age > 65 years: odds ratio (OR) = 3.33 (95% CI 1.89, 5.87; p < 0.0001); open approach: OR = 1.89 (95% CI 1.05, 3.38; p = 0.031)]. In this matched analysis, R-TAPP provides similar postoperative complications prior to discharge and a lower rate of postoperative complications through 30 days compared to open repair. R-TAPP is a promising and reproducible approach, and may facilitate adoption of minimally invasive repairs of inguinal hernias.

Short-Term Flooding Effects on Gas Exchange and Quantum Yield of Rabbiteye Blueberry (Vaccinium ashei Reade) 1

1986-01-01

Roots of 1.5-year-old `Woodard' rabbiteye blueberry plants (Vaccinium ashei Reade) were flooded in containers or maintained at container capacity over a 5-day period. Carbon assimilation, and stomatal and residual conductances were monitored on one fully expanded shoot/plant using an open flow gas analysis system. Quantum yield was calculated from light response curves. Carbon assimilation and quantum yield of flooded plants decreased to 64 and 41% of control values, respectively, after 1 day of flooding and continued decreasing to 38 and 27% after 4 days. Stomatal and residual conductances to CO2 also decreased after 1 day of flooding compared with those of unflooded plants with residual conductance severely limiting carbon assimilation after 4 days of flooding. Stomatal opening occurred in 75 to 90 minutes and rate of opening was unaffected by flooding. PMID:16664791

This study evaluated the expression of nonnutritive sucking habits and the presence of malocclusion in children using day nurseries' facilities. The 195 children (7-40 months) attending 18 public day nurseries were evaluated clinically in Ponta Grossa, Brazil. Statistical package software was used for descriptive, univariate, bivariate, and multiple logistic regressions of the data about the socioeconomic condition, educational family status, malocclusions, and prevalence of nonnutritive sucking habits among the children. The pacifier users had a statistically significant, explanatory association with open bite [odds ratio (OR) = 10.97; 95% confidence interval (CI): 4.95, 24.31; p < 0.0001]. The children older than 25 months had more open bite than younger children (OR = 6.07; 95% CI: 2.81, 13.11; p < 0.0001). Of the children examined, 35.4% had an anterior open bite, 0.51% had posterior cross-bite, and 1.03% showed finger-sucking habits. A high frequency of pacifier-sucking habits was found (52%), with a significant association between this habit and anterior open bite (p < 0.0001, OR = 7.49; 95% CI: 3.71, 15.15). The 126 children without open bite (36.5%) were pacifier users. There was suggestive, though nonsignificant, evidence of a difference in pacifier use by gender (males, 34%; females, 46%; p = 0.07). The 69 children with open bite (81.16%) were pacifier users and (18.84%) nonusers. The boys showed a slightly greater association with open bite (OR = 21.33; 95% CI: 6.12, 74.40; p < 0.0001) than girls (OR = 5.03; 95% CI: 1.26, 20.00; p = 0.02) in the age group of 25 to 40 months; however, it was not observed in younger children. Pacifier use is a predictor for open bite in children from the lower socioeconomic classes using day nurseries' facilities. The parents, guardians, and caregivers working in public day nurseries should be advised to monitor nonnutritive sucking habits in order to avoid or minimize the occurrence of malocclusion. It demonstrates that the permanence of the children in day nurseries may be linked with deleterious oral habits, and it discusses strategies to minimize the occurrence of alterations in the normal occlusion.

Should we use closed or open infusion containers for prevention of bloodstream infections?

PubMed

Rangel-Frausto, Manuel S; Higuera-Ramirez, Francisco; Martinez-Soto, Jose; Rosenthal, Victor D

2010-02-02

Hospitalized patients in critical care settings are at risk for bloodstream infections (BSI). Most BSIs originate from a central line (CL), and they increase length of stay, cost, and mortality. Open infusion containers may increase the risk of contamination and administration-related (CLAB) because they allow the entry of air into the system, thereby also providing an opportunity for microbial entry. Closed infusion containers were designed to overcome this flaw. However, open infusion containers are still widely used throughout the world.The objective of the study was to determine the effect of switching from open (glass, burettes, and semi-rigid) infusion containers to closed, fully collapsible, plastic infusion containers (Viaflex) on the rate and time to onset of central line-associated bloodstream infections CLABs. An open label, prospective cohort, active healthcare-associated infection surveillance, sequential study was conducted in four ICUs in Mexico. Centers for Disease Control National Nosocomial Infections Surveillance Systems definitions were used to define device-associated infections. A total of 1,096 adult patients who had a central line in place for >24 hours were enrolled. The CLAB rate was significantly higher during the open versus the closed container period (16.1 versus 3.2 CLAB/1000 central line days; RR = 0.20, 95% CI = 0.11-0.36, P < 0.0001). The probability of developing CLAB remained relatively constant in the closed container period (1.4% Days 2-4 to 0.5% Days 8-10), but increased in the open container period (4.9% Days 2-4 to 5.4% Days 8-10). The chance of acquiring a CLAB was significantly decreased (81%) in the closed container period (Cox proportional hazard ratio 0.19, P < 0.0001). Mortality was statistically significantly lower during the closed versus the open container period (23.4% versus 16.1%; RR = 0.69, 95% CI = 0.54-0.88, P < 0.01). Closed infusion containers significantly reduced CLAB rate, the probability of acquiring CLAB, and mortality.

The use of endoscopic resection as an alternative to open surgery for sinonasal malignancies has increased in the past 20 years. The National Cancer Database was queried for cases of sinonasal squamous cell carcinoma (SNSCC) without cervical or distant metastases that were treated surgically between 2010 and 2014. They were split into 2 groups based on surgical approach: open or endoscopic. Demographics, facility and insurance type, stage, tumor characteristics, postoperative treatment, 30-day readmission rate, 30- and 90-day mortality, and overall survival (OS) were compared between the 2 groups. Cox proportional hazard analysis was performed. Propensity score matching (PSM) was used to mimic a randomized, controlled trial. A total of 1,483 patients were identified: 353 (23.8%) received endoscopic and 1130 (76.2%) received open surgery. Age, gender, race, geographic region, tumor size, surgical margins, postoperative chemoradiation, and 30-day readmissions did not vary significantly between the 2 groups. Open surgery was more common in academic centers (62.8% vs 54.2%; p = 0.004), less common for tumors of the ethmoid and sphenoid sinus (p < 0.0001), less common for stage IVB tumors, and associated with longer hospital stay (mean, 4.67 days vs 2.50 days; p < 0.0001). Five-year OS (5Y-OS) was not significantly different between the 2 approaches (p = 0.953; open: 5Y-OS, 56.5%; 95% confidence interval, 51.3% to 61.6%; endoscopic: 5Y-OS, 46.0%; 95% confidence interval, 33.2% to 58.8%). In the PSM cohort of 652 patients, there was also no significant difference in OS (p = 0.850). Endoscopic surgery is an effective alternative to open surgery, even after accounting for confounding factors that may favor its use over the open approach. It is also associated with a shorter hospital stay. © 2017 ARS-AAOA, LLC.

Incisional hernia repair is one of the most common general surgery operations being performed today. With the advancement of laparoscopy since the 1990s, we have seen vast improvements in faster return to normal activity, shorter hospital stays and less post-operative narcotic use, to name a few. The key aims of this review were to measure the impact of minimally invasive surgery versus open surgery on health care utilization, cost, and work place absenteeism in the patients undergoing inpatient incisional/ventral hernia (IVH) repair. We analyzed data from the Truven Health Analytics MarketScan ® Commercial Claims and Encounters Database. Total of 2557 patients were included in the analysis. Of the patient that underwent IVH surgery, 24.5% (n = 626) were done utilizing minimally invasive surgical (MIS) techniques and 75.5% (n = 1931) were done open. Ninety-day post-surgery outcomes were significantly lower in the MIS group compared to the open group for total payment ($19,288.97 vs. $21,708.12), inpatient length of stay (3.12 vs. 4.24 days), number of outpatient visit (5.48 vs. 7.35), and estimated days off (11.3 vs. 14.64), respectively. At 365 days post-surgery, the total payment ($27,497.96 vs. $30,157.29), inpatient length of stay (3.70 vs. 5.04 days), outpatient visits (19.75 vs. 23.42), and estimated days off (35.71 vs. 41.58) were significantly lower for MIS group versus the open group, respectively. When surgical repair of IVH is performed, there is a clear advantage in the MIS approach versus the open approach in regard to cost, length of stay, number of outpatient visits, and estimated days off.

At present, we have evidence to do laparoscopic oncologic resections for endometrial cancer as proven by many prospective studies from abroad such as LAP2 by GOG. So, we have decided to assess the safety and feasibility of such a study in our population with the following as our primary objectives: (1) to study whether laparoscopy is better compared to open approach in terms of duration of hospital stay, perioperative morbidity and early recovery from surgical trauma and (2) to study whether the laparoscopic approach is noninferior to the open approach in terms of number of lymph nodes harvested in lymphadenectomy and rate of conversion to open surgery. We did a prospective nonrandomized comparative study of open versus laparoscopy approach for surgical staging of endometrial cancer from 16th May 2013 to 15th May 2015. To prove a significant difference in the hospital stay, we needed 29 patients in each arm. Thirty patients in each arm were enrolled for the study. The median duration of stay in the open arm was 7 days and in the laparoscopy arm it was 5 days. The advantage of 2 days in the laparoscopic arm was statistically significant ( P value 0.006). Forty percent of patients in the open arm had to stay in the hospital for more than 7 days whereas only 3% of patients in the laparoscopy arm required to stay for more than 7 days ( P value 0.001). This difference was statistically significant. There was no significant difference between the early complication rates between the two arms (20% in open vs. 13% in laparoscopy; P value 0.730). There was a conversion rate of 10% in laparoscopy. The median number of nodes harvested in open arm was 16.50 and in the laparoscopy arm, it was 13.50. The difference was not statistically significant ( P value 0.086). Laparoscopy approach for endometrial cancer staging is feasible in Indian patients and the short-term advantages are replicable with same oncologic safety as proved by randomized controlled trials.

Objectives Endovascular treatment of pararenal abdominal aortic aneurysm has gained terrain over the past decade, despite the substantial need for reinterventions during follow-up. However, open repair is still a well-established treatment option. With the current study we report the results of a consecutive series of elective primary open pararenal abdominal aortic aneurysm repair in a tertiary vascular referral centre, combined with an overview of current literature and pooled data analysis of perioperative mortality of open and endovascular pararenal abdominal aortic aneurysm repair. Methods A retrospective analysis of a prospective database of all elective open pararenal abdominal aortic aneurysm repairs in the St. Antonius Hospital between 2005 and 2014 was performed. Primary endpoint was 30-day mortality. Secondary endpoints were 30-day morbidity, new onset dialysis, reintervention free survival, and overall survival during follow-up. Results Between 2005 and 2014, 214 consecutive patients underwent elective open pararenal abdominal aortic aneurysm repair. Mean age was 69.8 (±7.1) years, 82.7% (177/214) were men, and mean abdominal aortic aneurysm diameter was 62 (±11) mm. Thirty-day mortality was 3.4%. Thirty-day morbidity was 27.1%, which predominantly consisted of pneumonia (18.7% (40/214)), cardiac events (3.3% (7/214)), and new onset dialysis (2.8% (6/214)). Estimated five-year overall survival rate was 74.2%. 0.9% (2/214) of patients required abdominal aortic aneurysm-related reintervention, and an additional 2.3% (5/214) required surgical repair of an incisional hernia. Pooled analysis of literature revealed a 30-day mortality of 3.0% for open pararenal repair and 1.9% for fenestrated endovascular repair. Conclusion Open pararenal abdominal aortic aneurysm repair in the era of increasing endovascular options results in acceptable perioperative morbidity and mortality rates. Mid-term reintervention rate is low compared to fenestrated endovascular aneurysm repair. Expertise with open repair still remains essential for treatment of pararenal abdominal aortic aneurysms in the near future, especially for those patients that are declined for endovascular treatment.

After cardiac surgery, functional residual capacity (FRC) after extubation is reduced significantly. We hypothesized that ventilation according to the open lung concept (OLC) attenuates FRC reduction after extubation. A prospective, single-center, randomized, controlled clinical study. Cardiothoracic operating room and intensive care unit of a university hospital. Sixty-nine patients scheduled for elective coronary artery bypass graft and/or valve surgery with cardiopulmonary bypass. Before surgery, patients were randomly assigned to three groups: (1) conventional ventilation (CV); (2) OLC, started after arrival in the intensive care unit (late open lung); and (3) OLC, started directly after intubation (early open lung). In both OLC groups, recruitment maneuvers were applied until Pao2/Fio2 was >375 Torr (50 kPa). No recruitment maneuvers were applied in the CV group. FRC was measured preoperatively and 1, 3, and 5 days after extubation. Peripheral hemoglobin saturation (Spo2) was measured daily till the third day after extubation while the patient was breathing room air. Hypoxemia was defined by an Spo2 value < or =90%. Averaged over the 5 postoperative days, FRC was significantly higher in the early open lung group and tended to be higher in the late open lung group, in comparison with the CV group (mean +/- sem: CV, 1.8 +/- 0.1; late open lung,1.9 +/- 0.1; and early open lung, 2.2 +/- 0.1l). In the CV group, 37% of the patients were hypoxic on the third day after extubation, compared with none of the patients in both OLC groups. After cardiac surgery, earlier application of OLC resulted in a significantly higher FRC and fewer episodes of hypoxemia than with CV after extubation.

Ground beef was either packaged in an atmosphere of 0.4% CO, 30% CO₂, and 69.6% N₂ (CO-MAP) or vacuum. After storage (48 h, 2-3°C), packages of CO-MAP and vacuum were opened and overwrapped with polyvinyl chloride. Other CO-MAP and vacuum packages were left intact. Packages were initially displayed for 7 days (2-3°C). Intact packages were further displayed up to 35 days before being opened and displayed (1 or 3 days). Intact CO-MAP packaged ground beef was always more red than intact vacuum-packaged ground beef. Color was relatively stable for both types of intact packages over 35 days of display. Upon opening CO-MAP packaged ground beef, the red color decreased slower than in ground beef from vacuum packages. Published by Elsevier Ltd.

2013-12-01

Robotic surgery has evolved from simple extirpative surgery to complex reconstructions even in infants. Data are lacking comparing surgical and direct costs to open approaches. We describe the feasibility, salient tips and outcomes of robot-assisted laparoscopic pyeloplasty compared to an open approach. We evaluated patients undergoing open pyeloplasty or robot-assisted laparoscopic pyeloplasty. Ten patients in each group met inclusion criteria. Mean patient age was 3.31 months in the open group and 7.3 months in the robotic group (p=0.02). Postoperative outcomes including length of stay (2.2 vs 2.1 days), estimated blood loss (6.5 vs 7.6 ml), days to regular diet (1 vs 1.1) and days to Foley catheter removal (1.3 vs 1.3) were similar between the open and robotic groups. Total operating time (199 vs 242 minutes) was significantly longer in the robotic group. Postoperative improvement in hydronephrosis was identical in both groups. Direct costs, excluding amortization, robotic cost, maintenance and depreciation, were $4,410 in the open group and $4,979 in the robotic group (p=0.10). In our preliminary experience robotic pyeloplasty in infants is feasible and safe. The immediate outcomes are similar to those of an open approach. The robotic technique in infants currently has the benefits of improved esthetic appearance, improved pain control and similar direct costs compared to the traditional open approach.

Orthodontic treatment-induced temporal alteration of jaw-opening reflex excitability.

PubMed

2017-10-01

The impairment of orofacial motor function during orthodontic treatment needs to be addressed, because most orthodontic patients experience pain and motor excitability would be affected by pain. In the present study, the temporal alteration of the jaw-opening reflex excitability was investigated to determine if orthodontic treatment affects orofacial motor function. The excitability of jaw-opening reflex evoked by electrical stimulation on the gingiva and recorded bilaterally in the anterior digastric muscles was evaluated at 1 (D1), 3 (D3), and 7 days (D7) after orthodontic force application to the teeth of right side; morphological features (e.g., osteoclast genesis and tooth movement) were also evaluated. To clarify the underlying mechanism of orthodontic treatment-induced alteration of orofacial motor excitability, analgesics were administrated for 1 day. At D1 and D3, orthodontic treatment significantly decreased the threshold for inducing the jaw-opening reflex but significantly increased the threshold at D7. Other parameters of the jaw-opening reflex were also evaluated (e.g., latency, duration and area under the curve of anterior digastric muscles activity), and only the latency of the D1 group was significantly different from that of the other groups. Temporal alteration of the jaw-opening reflex excitability was significantly correlated with changes in morphological features. Aspirin (300 mg·kg -1 ·day -1 ) significantly increased the threshold for inducing the jaw-opening reflex, whereas a lower dose (75-150 mg·kg -1 ·day -1 ) of aspirin or acetaminophen (300 mg·kg -1 ·day -1 ) failed to alter the jaw-opening reflex excitability. These results suggest that an increase of the jaw-opening reflex excitability can be induced acutely by orthodontic treatment, possibly through the cyclooxygenase activation. NEW & NOTEWORTHY It is well known that motor function is affected by pain, but the effect of orthodontic treatment-related pain on the trigeminal motor excitability has not been fully understood. We found that, during orthodontic treatment, trigeminal motor excitability is acutely increased and then decreased in a week. Because alteration of trigeminal motor function can be evaluated quantitatively by jaw-opening reflex excitability, the present animal model may be useful to search for alternative approaches to attenuate orthodontic pain.

The open lung approach is a mechanical ventilation strategy involving lung recruitment and a decremental positive end-expiratory pressure trial. We compared the Acute Respiratory Distress Syndrome network protocol using low levels of positive end-expiratory pressure with open lung approach resulting in moderate to high levels of positive end-expiratory pressure for the management of established moderate/severe acute respiratory distress syndrome. A prospective, multicenter, pilot, randomized controlled trial. A network of 20 multidisciplinary ICUs. Patients meeting the American-European Consensus Conference definition for acute respiratory distress syndrome were considered for the study. At 12-36 hours after acute respiratory distress syndrome onset, patients were assessed under standardized ventilator settings (FIO2≥0.5, positive end-expiratory pressure ≥10 cm H2O). If Pao2/FIO2 ratio remained less than or equal to 200 mm Hg, patients were randomized to open lung approach or Acute Respiratory Distress Syndrome network protocol. All patients were ventilated with a tidal volume of 4 to 8 ml/kg predicted body weight. From 1,874 screened patients with acute respiratory distress syndrome, 200 were randomized: 99 to open lung approach and 101 to Acute Respiratory Distress Syndrome network protocol. Main outcome measures were 60-day and ICU mortalities, and ventilator-free days. Mortality at day-60 (29% open lung approach vs. 33% Acute Respiratory Distress Syndrome Network protocol, p = 0.18, log rank test), ICU mortality (25% open lung approach vs. 30% Acute Respiratory Distress Syndrome network protocol, p = 0.53 Fisher's exact test), and ventilator-free days (8 [0-20] open lung approach vs. 7 [0-20] d Acute Respiratory Distress Syndrome network protocol, p = 0.53 Wilcoxon rank test) were not significantly different. Airway driving pressure (plateau pressure - positive end-expiratory pressure) and PaO2/FIO2 improved significantly at 24, 48 and 72 hours in patients in open lung approach compared with patients in Acute Respiratory Distress Syndrome network protocol. Barotrauma rate was similar in both groups. In patients with established acute respiratory distress syndrome, open lung approach improved oxygenation and driving pressure, without detrimental effects on mortality, ventilator-free days, or barotrauma. This pilot study supports the need for a large, multicenter trial using recruitment maneuvers and a decremental positive end-expiratory pressure trial in persistent acute respiratory distress syndrome.

The objective of this study is to investigate the influences of percutaneous nephrolithotomy (PNL) and open surgery nephrolithotomy on the systemic stress response, SIRS and renal function. Forty patients with kidney calculi were enrolled in the study. Twenty cases were randomized to the PNL group and the other twenty cases to the open surgery group. Levels of C-reactive protein (CRP), interleukin-6(IL-6), β(2)-microglobulin (β(2)-MG), respiration rate, heart rate, body temperature and white blood cell counts were examined. CRP and IL-6 were measured in all patients pre-operatively and on post-operative days 1, 3 and 6, respectively. There was significant difference in their pre- and post-operation levels (P < 0.05), with the peak of CRP and IL-6 observed at post-operative days 3 and 1, respectively. There was significant difference in both CRP and IL-6 between the two groups (P < 0.05). At post-operative day 1, there were 5 cases of SIRS in PNL group and 12 cases in open surgery group; there was significant difference between the two groups (P < 0.05). Serum β(2)-MG levels were measured as the same time as CRP and no significant changes were observed within or between the groups (P > 0.05). Urine β(2)-MG levels were also measured. There was significant difference between pre- and the first day post-PNL (P < 0.05); there was no significant difference between pre- and the third and sixth day post-PNL (P > 0.05). There was significant difference between pre- and first and third day post-open surgery (P < 0.05); but there was no significant difference between pre- and the sixth day post-open surgery (P > 0.05). There was significant difference between two groups at the first, third and sixth days (P < 0.05). The systemic stress response is activated both in PNL group and open surgery group to some extent. The degree of stress response of PNL is lower than that of open surgery, proving the advantages of PNL with reference to serum immunology. There were cases in both the groups with SIRS, but the degree of SIRS in PNL group was lesser than the other group. Both the groups have no obvious effect on glomerular filtration function after operation and have effect on renal tubular reabsorption in the early stage after operation; but the recovery of the PNL group is faster than the open surgery group. It is thus shown that PNL is much safer and more feasible and has lesser effect on renal function.

The "Dental students training to address the needs of each individual patient: enhancement of ability to make a comprehensive diagnosis and treatment plans with high ethical standards and good communication skills", project launched at Tokyo Dental College was adopted by the Ministry of Education, Culture, Sports, Science and Technology as part of its "Program for Promoting University Education and Student Support, Theme A: Program for Promoting University Education Reform" in 2009. One of the main goals of this subject is "the establishment of Patient Community". Patient Community members allowed students to gain a more realistic experience of clinical practice than simulated patients. The Patient Community consists of patients and members of the parents' association who have agreed to cooperate for the advancement of dental education, becoming involved in dental student education through Communication Studies, which are held for first- to fourth-year students. Patient Community members were recruited at the open lectures (15 times, between July 10, 2010 and November 30, 2011). The Patient Community comprised 24 members, including 8 men and 16 women by November 30, 2011. The cumulative number of attendees in Communication Studies (I-IV, 6 times) was 35, including 13 men and 22 women. Fourteen people applied for admission on the day of the open lecture. Seven people signed up between 1 and 7 days after the open lecture. On the other hand, only 3 people applied within 8 to 9 days after the open lecture. However, interestingly, the ratio of the attendance for Communication Studies by Patient Community members who applied 8 to 9 days after the open lecture was higher than that of members who applied for admission on the day of the open lecture. Since the number of Patient Community members is insufficient for the purposes of the Patient Community, it is necessary to think about how recruitment methods can be made more effective and how such open lectures should be conducted in future.

To evaluate the effects of a pico-tesla electromagnetic field (PTEF) on healing of sutured and open skin wounds and clinicopathologic variables in rats. 64 male Fischer-344 rats. An incision made in the dorsal aspect of the neck was sutured (n = 32) or left open to heal (32). In each group, 16 rats were not PTEF-treated (controls). Wound treatment consisted of exposure to a PTEF once daily. Rats in each group were euthanatized at days 2, 4, 7, and 14. Wounds were evaluated via tensiometry (sutured wounds), digital planimetry (open wounds), laser Doppler perfusion imaging, bacteriologic culture, and histologic examination. Blood samples were collected from all rats for analysis. At day 14, sutured wounds in PTEF-treated rats were stronger (ultimate stress) and tougher (strain energy) than were sutured wounds in control rats. Open wounds in PTEF-treated rats contracted more quickly at days 2 and 4 than did those in control rats. Compared with control wounds, histologic changes (indicative of improved healing) in sutured and open wounds in PTEF-treated rats were detected as early as day 4. Laser Doppler perfusion measurements, results of CBCs, serum biochemical analyses, and bacteriologic cultures were not different between groups. Exposure to the PTEF caused no adverse effects on clinicopathologic, histologic, or bacteriologic variables tested in this study. It appears that PTEF is a safe form of adjuvant treatment for wounds and improves strength of sutured wounds and speeds contraction of open wounds.

Objective: To compare tension-free open mesh hernioplasty under local anaesthetic with transabdominal preperitoneal laparoscopic hernia repair under general anaesthetic. Design: A randomised controlled trial of 403 patients with inguinal hernias. Setting: Two acute general hospitals in London between May 1995 and December 1996. Subjects: 400 patients with a diagnosis of groin hernia, 200 in each group. Main outcome measures: Time until discharge, postoperative pain, and complications; patients’ perceived health (SF-36), duration of convalescence, and patients’ satisfaction with surgery; and health service costs. Results: More patients in the open group (96%) than in the laparoscopic group (89%) were discharged on the same day as the operation (χ2=6.7; 1 df; P=0.01). Although pain scores were lower in the open group while the effect of the local anaesthetic persisted (proportional odds ratio at 2 hours 3.5 (2.3 to 5.1)), scores after open repair were significantly higher for each day of the first week (0.5 (0.3 to 0.7) on day 7) and during the second week (0.7 (0.5 to 0.9)). At 1 month there was a greater improvement (or less deterioration) in mean SF-36 scores over baseline in the laparoscopic group compared with the open group on seven of eight dimensions, reaching significance on five. For every activity considered the median time until return to normal was significantly shorter for the laparoscopic group. Patients randomised to laparoscopic repair were more satisfied with surgery at 1 month and 3 months after surgery. The mean cost per patient of laparoscopic repair was £335 (95% confidence interval £228 to £441) more than the cost of open repair. Conclusion: This study confirms that laparoscopic hernia repair has considerable short term clinical advantages after discharge compared with open mesh hernioplasty, although it was more expensive. Key messages In the 4 hours after surgery laparoscopic hernia repair with general anaesthesia causes more pain than open repair with local anaesthesia (mainly because of the anaesthesia used) and necessitates longer stay in hospital. Laparoscopic hernia repair, however, causes less pain than open hernia repair during the first 2 weeks after discharge Laparoscopic hernia repair results in fewer episodes of wound infection, persistent local pain, genital swelling, numbness, and constipation than open repair. Urinary disturbances are more common after laparoscopic than after open repair Patients’ perception of health 1 month after the operation (assessed with the SF-36) and satisfaction with treatment is superior for laparoscopic patients who also have a shorter period of convalescence after surgery The health service cost of day case laparoscopic repair is £335 more than the cost of open mesh hernioplasty performed on a day case basis PMID:9657784

To determine the difference in infection rate between 24h versus five days of prophylactic antibiotic use in management of Gustilo II open tibia fractures. Unblinded randomized control trial. Accident and Emergency, orthopedic wards and outpatient clinics at Kenyatta National Hospital (KNH). The study involved patients aged 18-80 years admitted through accident and emergency department with Gustilo II traumatic open tibia fractures. Patients were randomized into either 24hour or five day group and antibiotics started for 24hours or five days after surgical debridement. The wounds were exposed and scored using ASEPSIS wound scoring system for infection after 48h, 5days and at 14days. The main outcomes of interest were presence of infection at days 2, 5 and 14 and effect of duration to antibiotic administration on infection rate. There was no significant difference in infection rates between 24-hour and 5-day groups with infection rates of 23% (9/40) vs. 19% (7/37) respectively (p=0.699). The infection rate was significantly associated with time lapsed before administration of antibiotics (p=0.004). In the use of prophylactic antibiotics for the management of Gustilo II traumatic open tibia fractures, there is no difference in infection rate between 24hours and five days regimen but time to antibiotic administration correlates with infection rate. Antibiotic use for 24hours only has proven adequate prophylaxis against infection. This is underlined in our study which we hope shall inform practice in our setting. A larger, more appropriately controlled study would be useful. Copyright © 2016 Elsevier Ltd. All rights reserved.

We hypothesize that patients who survive 30 days or more following repair of ruptured AAA (RAAA) performed by open technique have a life expectancy no different to those patients surviving 30 days or more following elective AAA repair, or compared to a general age-matched population. Between 1987 and December 2014, 620 consecutive patients were treated by the principal author for aortic aneurysmal disease. Two subgroups were selected from this population, elective open abdominal repair (215) and RAAA open repair (105). Comparable age-matched life curves with the general population were used from the Australian Bureau of Statistics for each patient according to gender, age and date of presentation. Statistical comparison was by Kaplan-Meier survival analysis. Both the open and RAAA groups were well matched for age and sex. There was no statistical difference between RAAA survival and an age-matched population P = 0.23, or was there any difference between open repair and an age-matched population, P = 0.1. Survival curves for RAAA and open repair were similar, P = 0.98. For elective open repair 1-, 5-, 10-, 15- and 20-year survival was 93.6, 71.2, 40, 17 and 2% respectively. Corresponding results for RAAA were 92.5, 74, 36.7, 13.5 and 5% respectively. Open AAA repair for RAAA or elective aneurysm treatment restores predicted life expectancy for those patients surviving 30 days or more and is therefore a durable method of treatment for this condition. © 2016 Royal Australasian College of Surgeons.

No randomized trial exists that specifically addresses the issue of laparoscopic bilateral inguinal hernia repair. The purpose of the present prospective, randomized, controlled, clinical study was to assess short- and long-term results when comparing simultaneous bilateral hernia repair by an open, tension-free anterior approach with laparoscopic "bikini mesh" posterior repair. Forty-three low-risk male patients with bilateral primary inguinal hernia were randomly assigned to undergo either laparoscopic preperitoneal "bikini mesh" hernia repair (TAPP) or open Lichtenstein hernioplasty. There was no difference in operating time between the two groups. The mean cost of laparoscopic hernioplasty was higher (P < 0.001). The intensity of postoperative pain was greater in the open hernia repair group at 24 hours, 48 hours, and 7 days after surgery (P < 0.001), with a greater consumption of pain medication among these patients (P < 0.05). The median time to return to work was 30 days for the open hernia repair group and 16 days for the laparoscopic "bikini mesh" repair group (P < 0.05). Only 1 asymptomatic recurrence (4.3%) was discovered in the open group. The laparoscopic approach to bilateral hernia with "bikini mesh" appears to be preferable to the open Lichtenstein tension-free hernioplasty in terms of the postoperative quality of life and interruption of occupational activity.

To compare the efficacy of adrafinil, propentofylline, and nicergoline for enhancing behavior of aged dogs. 36 Beagles between 9 and 16 years old. Dogs were randomly assigned to receive adrafinil (20 mg/kg of body weight, PO, q 24 h; n = 12), propentofylline (5 mg/kg, PO, q 12 h; 12), or nicergoline (0.5 mg/kg, PO, q 24 h; 12) for 33 days. Baseline behaviors in an open field and in kennels (home cage) were recorded before treatment. After treatment, behaviors in the open field were recorded 2 hours after drug administration on days 2, 15, and 28, and 10 hours after administration on days 7, 20, and 33. Behaviors in the home cage were recorded 2 and 7 hours after drug administration on days 4, 17, and 30. Treatment with adrafinil resulted in a significant increase in locomotion in each of the open-field tests and an increase in locomotion in the home cage. This latter increase was smaller and more variable than that in the open field. Locomotion was not affected by treatment with propentofylline or nicergoline. In the open field, sniffing decreased over time in all 3 groups, but the largest decline was observed in the propentofylline group. Treatment with adrafinil may improve the quality of life of aged dogs by increasing exploratory behavior and alertness.

Habituation of medaka (Oryzias latipes) demonstrated by open-field testing.

PubMed

Matsunaga, Wataru; Watanabe, Eiji

2010-10-01

Habituation to novel environments is frequently studied to analyze cognitive phenotypes in animals, and an open-field test is generally conducted to investigate the changes that occur in animals during habituation. The test has not been used in behavioral studies of medaka (Oryzias latipes), which is recently being used in behavioral research. Therefore, we examined the open-field behavior of medaka on the basis of temporal changes in 2 conventional indexes of locomotion and position. The findings of our study clearly showed that medaka changed its behavior through multiple temporal phases as it became more familiar with new surroundings; this finding is consistent with those of other ethological studies in animals. During repeated open-field testing on 2 consecutive days, we observed that horizontal locomotion on the second day was less than that on the first day, which suggested that habituation is retained in fish for days. This temporal habituation was critically affected by water factors or visual cues of the tank, thereby suggesting that fish have spatial memory of their surroundings. Thus, the data from this study will afford useful fundamental information for behavioral phenotyping of medaka and for elucidating cognitive phenotypes in animals. Copyright (c) 2010 Elsevier B.V.

2013-01-01

This study set out to assess the neurobehavioral effects of subchronic, oral bromocriptine methanesulfonate using the open field and the Y-maze in healthy male mice. Sixty adult Swiss albino mice were assigned into three groups. Controls received normal saline, while test groups received bromocriptine methanesulfonate at 2.5 and 5 mg/kg/day, respectively, for a period of 21 days. Neurobehavioral tests were carried out on days 1 and 21 after administration. Open field assessment on day 1 after administration revealed significant increase in grooming at 2.5 and 5 mg/kg, while horizontal and vertical locomotion showed no significant changes. Day 1 also showed no significant changes in Y-maze alternation. On day 21, horizontal locomotion, rearing, and grooming were increased significantly at 2.5 and 5 mg/kg doses after administration; also, spatial memory was significantly enhanced at 2.5 mg/kg. In conclusion, the study demonstrates the ability of oral bromocriptine to affect neurobehavior in normal mice. It also suggests that there is a cumulative effect of oral bromocriptine on the behaviors studied with more changes being seen after subchronic administration rather than after a single oral dose.

Simultaneous repair of bilateral groin hernias: open or laparoscopic approach?

PubMed

Krähenbühl, L; Schäfer, M; Schilling, M; Kuzinkovas, V; Büchler, M W

1998-08-01

A persistent problem in hernia surgery concerns the repair of bilateral inguinal hernias. A retrospective analysis of 78 patients with bilateral inguinal hernias was performed. Hernia repair was performed either by an open anterior access (modified Shouldice repair) or a laparoscopic posterior approach (TAPP repair). The two patient groups were similar with regard to ASA classification, age, and sex. The intraoperative complication rate was low (2.6% to 7.8%), whereas postoperative complications occurred more frequently (7.7% to 15.4%). The recurrence rate was low in both groups: 5.1% for the open group and 1.3% for the laparoscopic group. The mean hospital stay was 4 days for both groups, and the mean off-work times were 56.4 days and 17.9 days for the open and laparoscopic group, respectively (p < 0.05). Both procedures gave satisfactory results. The main advantages of the laparoscopic approach are the shorter convalescence time and quicker return to work.

To assess national trends of iatrogenic complications and associated burden of care among patients undergoing open and minimally invasive prostatectomy using a population-based cohort. Using the nationally representative cohort, we identified patients who were diagnosed with prostate cancer, and underwent prostatectomy during 2001 and 2011. We determined the risk of iatrogenic complication and length of stay (LOS) over time among open and minimally invasive surgery (MIS) patients. Hierarchical multivariable logistic regression was performed to assess the changes over time and elucidate independent predictors of iatrogenic complications. We identified 556,932 and 219,434 prostate cancer patients undergoing open and minimally invasive prostatectomy. We found that iatrogenic complications for MIS were less frequent in later years (years 09-11 vs. year 01-02 odds ratio (OR), 0.21; 95% confidence intervals (CI), 0.09-0.40). MIS was associated with higher risk of iatrogenic complications in early period (years 01-02 OR, 3.81; 95% CI, 1.72-8.41), but lower risk in late period (years 09-11 OR 0.72 95% CI 0.61-0.86). Patients who experienced iatrogenic complications tended to have longer LOS (Median: Open vs. MIS, 4 days vs. 3 day) than those who didn't (Median: Open vs. MIS, 2 days vs. 1 day), regardless of procedure type. We found that minimally invasive prostatectomy is associated with lower risk of iatrogenic complications when compared with open surgery (OS). However, as "learning curve" is overcome over time, MIS becomes safer than OS. Iatrogenic complications are not benign and seem to be associated with higher burden of inpatient care.

Physicochemical and microbiological stability of azathioprine in InOrpha suspending agent studied under various conditions.

PubMed

Amin, Alexandre; Bourget, Philippe; Vidal, Fabrice; Cartier, François; Beauvais, Raphaëlle; Afonso, Veronica Do Nascimento

2015-01-01

Azathioprine is an antineoplastic antimetabolite drug currently used as an immunosuppressive agent after organ transplantation and for several dysimmunitary diseases. The usual daily dose ranges from 1 to 5 mg/kg orally. Azathioprine is marketed in France under the trade name Imurel in tablet form for oral administration that contains either 25 mg or 50 mg of the active ingredient. This Galenic formulation is not suitable for pediatric use and often requires a grinding operation or a dose fractionation to facilitate administration. In addition to a potential risk of imprecision in the administered dose, tablet grinding might unnecessarily expose nurses and families to a toxic compound. To overcome this problem, the objective of this study was to develop and evaluate the physicochemical and microbiological stabilities of azathioprine in a sugar-free, alcohol-free, and paraben-free InOrpha suspending agent. The studied samples were formulated into a 10-mg/mL suspension and stored in 24 plastic bottles of 60 mL at two different temperature conditions (between 2 degrees C to 8 degrees C and room temperature). Two series of 12 samples were tested for physicochemical stability using high-performance liquid chromatography as well as for a microbiological status for 35 days (daily opening of the bottles from day 0 of compounding) and for 56 days, upon daily flask opening (first opening at day 28 from compounding and daily opening for 28 consecutive days). The high-performance liquid chromatography method developed is linear, accurate, precise, and robust. In addition, a forced degradation study validated the selectivity and the specificity requirements of the method validated as stability indicating. At room temperature storage, high-performance liquid chromatography analysis showed that tested samples had concentrations ranging from 90% to 110% of the initial concentration throughout the course of the study. Microbiological status remained stable during the 56 days of investigation. Based on the data collected, the study led to the development of a new Galenic formulation of azathioprine that is suitable for pediatric use and can be safely stored at room temperature for 28 days (before and after opening for a maximum of 56 consecutive days).

Turning the rumor of May 11, 2011 earthquake prediction In Rome, Italy, into an information day on earthquake hazard

NASA Astrophysics Data System (ADS)

Amato, A.; Cultrera, G.; Margheriti, L.; Nostro, C.; Selvaggi, G.; INGVterremoti Team

2011-12-01

A devastating earthquake had been predicted for May 11, 2011 in Rome. This prediction was never released officially by anyone, but it grew up in the Internet and was amplified by media. It was erroneously ascribed to Raffaele Bendandi, an Italian self-taught natural scientist who studied planetary motions. Indeed, around May 11, 2011, a planetary alignment was really expected and this contributed to give credibility to the earthquake prediction among people. During the previous months, INGV was overwhelmed with requests for information about this supposed prediction by Roman inhabitants and tourists. Given the considerable mediatic impact of this expected earthquake, INGV decided to organize an Open Day in its headquarter in Rome for people who wanted to learn more about the Italian seismicity and the earthquake as natural phenomenon. The Open Day was preceded by a press conference two days before, in which we talked about this prediction, we presented the Open Day, and we had a scientific discussion with journalists about the earthquake prediction and more in general on the real problem of seismic risk in Italy. About 40 journalists from newspapers, local and national tv's, press agencies and web news attended the Press Conference and hundreds of articles appeared in the following days, advertising the 11 May Open Day. The INGV opened to the public all day long (9am - 9pm) with the following program: i) meetings with INGV researchers to discuss scientific issues; ii) visits to the seismic monitoring room, open 24h/7 all year; iii) guided tours through interactive exhibitions on earthquakes and Earth's deep structure; iv) lectures on general topics from the social impact of rumors to seismic risk reduction; v) 13 new videos on channel YouTube.com/INGVterremoti to explain the earthquake process and give updates on various aspects of seismic monitoring in Italy; vi) distribution of books and brochures. Surprisingly, more than 3000 visitors came to visit INGV headquarters until 9 p.m.: families, school classes with and without teachers, civil protection groups, journalists. This initiative, built up in a few weeks, had a very large feedback, also due to the media highlighting the presumed prediction. Although we could not rule out the possibility of a strong earthquake in central Italy (with effects in Rome) we tried to explain the meaning of short term earthquake prediction vs. probabilistic seismic hazard assessment. Despite many people remained with the fear (many decided to take a day off and leave the town or stay in public parks), we contributed to reduce this feeling and therefore the social cost of this strange Roman day. Moreover, another lesson learned is that these (fortunately sporadic) circumstances, when people's attention is high, are important opportunities for science communication. We thank all the INGV colleagues who contributed to the May 11 Open Day, in particular the Press Office, the Educational and Outreach laboratory, the Graphics Laboratory and SissaMedialab. P.S. no large earthquake happened

Periadventitial Application of Rapamycin-Loaded Nanoparticles Produces Sustained Inhibition of Vascular Restenosis

2014-01-01

Open vascular reconstructions frequently fail due to the development of recurrent disease or intimal hyperplasia (IH). This paper reports a novel drug delivery method using a rapamycin-loaded poly(lactide-co-glycolide) (PLGA) nanoparticles (NPs)/pluronic gel system that can be applied periadventitially around the carotid artery immediately following the open surgery. In vitro studies revealed that rapamycin dispersed in pluronic gel was rapidly released over 3 days whereas release of rapamycin from rapamycin-loaded PLGA NPs embedded in pluronic gel was more gradual over 4 weeks. In cultured rat vascular smooth muscle cells (SMCs), rapamycin-loaded NPs produced durable (14 days versus 3 days for free rapamycin) inhibition of phosphorylation of S6 kinase (S6K1), a downstream target in the mTOR pathway. In a rat balloon injury model, periadventitial delivery of rapamycin-loaded NPs produced inhibition of phospho-S6K1 14 days after balloon injury. Immunostaining revealed that rapamycin-loaded NPs reduced SMC proliferation at both 14 and 28 days whereas rapamycin alone suppressed proliferation at day 14 only. Moreover, rapamycin-loaded NPs sustainably suppressed IH for at least 28 days following treatment, whereas rapamycin alone produced suppression on day 14 with rebound of IH by day 28. Since rapamycin, PLGA, and pluronic gel have all been approved by the FDA for other human therapies, this drug delivery method could potentially be translated into human use quickly to prevent failure of open vascular reconstructions.

Unplanned Robotic-Assisted Conversion-to-Open Colorectal Surgery is Associated with Adverse Outcomes.

Laparoscopic conversion-to-open colorectal surgery is associated with worse outcomes when compared to operations completed without conversion. Consequences of robotic conversion have not yet been determined. The purpose of this study is to compare short-term outcomes of converted robotic colorectal cases with those that are completed without conversion, as well as with cases done by the open approach. The ACS-NSQIP database was queried for patients who underwent robotic completed, robotic converted-to-open, and open colorectal resection between 2012 and 2015. Propensity scores were estimated using gradient-boosted machines and converted to weights. Generalized linear models were fit using propensity score-weighted data. A total of 25,253 patients met inclusion criteria-21,356 (84.5%) open, 3663 (14.5%) robotic completed, and 234 (0.9%) conversions. Conversion rate was 6.0%. Converted cases had significantly higher 30-day mortality rate, higher complication rate, and longer hospital length of stay than completed cases. Converted patients also had significantly higher rates of the following complications: surgical site infections, cardiac complications, deep venous thrombosis, postoperative ileus, postoperative re-intubation, renal failure, and 30-day reoperation. Compared to the open approach, converted patients had significantly more cardiac complications, postoperative reintubation, and longer operating times with no significant difference in 30-day mortality. Unplanned robotic conversion-to-open is associated with worse outcomes than completed cases and outcomes that more closely resemble traditional open colorectal surgery. Patients should be counseled with regard to minimally invasive conversion rates and outcomes. The continued pursuit of technological advancements that decrease the risk for conversion in minimally invasive colorectal surgery is clearly warranted.

Comparison of inflammatory responses following robotic and open colorectal surgery: a prospective study.

2017-03-01

Robotic colorectal surgery continues to rise in popularity, but there remains little evidence on the stress response following the procedure. The aim of this study was to evaluate the inflammatory response to robotic colorectal surgery and compare it with the response generated by open colorectal surgery. This was a prospective nonrandomized comparative study involving 61 patients with colorectal cancer. The evaluation of inflammatory response to either robotic or open colorectal surgery was expressed as changes in interleukin-1β, interleukin-1 receptor antagonist, interleukin-6, tumor necrosis factor-α, C-reactive protein, and procalcitonin during the first three postoperative days. Of the 61 patients, 33 underwent robotic colorectal surgery while 28 had open colorectal surgery. Groups were comparable with respect to age, sex, BMI, cancer stage, and type of resection. The relative increase of interleukin-1 receptor antagonist at 8 h postoperative, compared to baseline, was higher in the open group (P = 0.006). The decrease of interleukin-1 receptor antagonist on postoperative days 1 and 3, compared to the maximum at 8 h, was more pronounced in the open group than in the robotic group (P = 0.008, P = 0.006, respectively), and the relative increase of interleukin-6 at 8 h after incision was higher in the open group (P = 0.007). The relative increase of procalcitonin on postoperative days 1 and 3 was higher in the open group than the robotic group (P < 0.001, P = 0.004, respectively). This study shows that when compared with open colorectal surgery, robotic colorectal surgery results in a less pronounced inflammatory response and more pronounced anti-inflammatory action.

Open versus laparoscopic Roux-en-Y gastric bypass: a comparative study of over 25,000 open cases and the major laparoscopic bariatric reported series.

2006-06-01

Laparoscopic bariatric surgery has experienced a rapid expansion of interest over the past 5 years, with a 470% increase. This rapid expansion has markedly increased overall cost, reducing surgical access. Many surgeons believe that the traditional open approach is a cheaper, safer, equally effective alternative. 16 highly experienced "open" bariatric surgeons with a combined total of 25,759 cases representing >200 surgeon years of experience, pooled their open Roux-en-Y gastric bypass (ORYGBP) data, and compared their results to the leading laparoscopic (LRYGBP) papers in the literature. In the overall series, the incisional hernia rate was 6.4% using the standard midline incision. Utilizing the left subcostal incision (LSI), it was only 0.3%. Return to surgery in <30 days was 0.7%, deaths 0.25%, and leaks 0.4%. Average length of stay was 3.4 days, and return to usual activity 21 days. Small bowel obstruction was significantly higher with the LRYGBP. Surgical equipment costs averaged approximately $3,000 less for "open" cases. LRYGBP had an added expense for longer operative time. This more than made up for the shorter length of stay with the laparoscopic approach. The higher cost, higher leak rate, higher rate of small bowel obstruction, and similar long-term weight loss results make the "open" RYGBP our preferred operation. If the incision is taken out of the equation (i.e. use of the LSI), the significant advantages of the open technique become even more obvious.

The aim of this study was to determine the effect of feeding high gamma-aminobutyric acid (GABA)-containing black sticky rice giant embryo (BSRGE, Oryza sativa L.) on anxiety-related behavior of C57BL/6 mice. Experimental feedstuff (BSRGE with high GABA+AIN-76A) and control (AIN-76A) were provided to C57BL/6 mouse for 10 days. Antianxiety effects of BSRGE with high GABA were measured using an elevated plus maze. On day 8, the number of open arm entries by GABA and control groups were 1.10 ± 1.60 (mean ± SD) and 0.00 ± 0.00 (P = .030). On day 10, the number of open arm entries by the GABA group was 2.00 ± 1.89, which was significantly (P = .025) higher than that in the control group (0.40 ± 0.84). On day 8, the time the mice spent in open arm in the GABA group and control group was 3.60 ± 7.06 and 0.00 ± 0.00 sec (P = .068), respectively. On day 10, the time the mice in the GABA and control groups spent in open arm was 6.20 ± 5.35 sec and 1.80 ± 3.82 sec (P = .042), respectively. In repeated analysis of variance for the number of entries into open arm and time spent in open arm, significant differences were found between the two groups. Therefore, BSRGE with high GABA content might have an antianxiety effect. This study can serve as a preliminary study so that further antianxiety effects of BSRGE can be determined in more extended animal or clinical research studies in the future.

To determine whether use of a closed urine collection system would decrease the incidence of nosocomial bacteriuria in hospitalized dogs, compared with use of an open urine collection system (used, sterile IV bags). Randomized controlled trial. 51 hospitalized dogs requiring indwelling urinary catheterization for >or= 24 hours. Dogs were randomly assigned to an open or closed urine collection system group. A standardized protocol for catheter placement and maintenance was followed for all dogs. A baseline urine sample was collected via cystocentesis for aerobic bacterial culture, with additional urine samples obtained daily from the urine collection reservoir. 27 dogs were assigned to the open urine collection system group, and 24 were assigned to the closed urine collection system group. The incidence of nosocomial bacteriuria in dogs with open urine collection systems (3/27 [11.1%]) was not significantly different from incidence in dogs with closed urine collection systems (2/24 [8.3%]). Median duration of catheterization was 2 days for dogs in both groups; the range was 1 to 7 days for dogs in the open group and 1 to 5 days for dogs in the closed group. Results suggested that for dogs requiring short-term indwelling urinary catheterization, the type of urine collection system (open vs closed) was not associated with likelihood of developing nosocomial bacteriuria. Use of a strict protocol for urinary catheter placement and maintenance was likely key in the low incidence of nosocomial bacteriuria in the present study.

The present study investigated the effect of combined exposure of pyridostigmine bromide (PB) and chronic shaker stress on acoustic startle responses (ASR), pre-pulse inhibition (PPI) and open field behavior of adult C57BL/6J mice. PB (10 mg kg(-1) day(-1) for 7 days) or saline was administered subcutaneously using osmotic Alzet minipumps implanted under the skin on the back of the mice. At the same time, the mice were exposed to 7 days of intermittent shaker stress. They were tested for ASR (100 dB and 120 dB stimuli) and PPI (70 dB + 100 dB and 70 dB + 120 dB) in the acoustic startle monitor system. The mice were assessed during the shaker stress on days 2 and 7 and 7, 14, 21 and 28 days after discontinuation of treatment. Separate groups of mice were tested in the open field in 15 min sessions on days 1, 3 and 6 during shaker stress and PB treatment. Exposure of mice to PB resulted in an exaggerated ASR, reduced PPI and non-significant decrease in locomotor activity. These behavioral changes were apparent only during exposure to PB. Repeated shaker stress did not have any effect on sensorimotor functions or open field behavior of mice. There was no prolonged or delayed effect of PB and/or stress on individual behavioral variables. The study found C57BL/6J mice to be behaviorally sensitive to PB treatment.

Records were obtained over a 3 year period from six Holstein dairy farms of 300 to 500 cows each in the Phoenix, Ariz. area. Dairies were selected on the basis of similar management practices, herd size, milk production and facilities (with the exception of cooling systems). Microclimatic modifications (two dairies each) were shade only (approximately 3.7 m2/cow), evaporative-cooled shades and low-pressure water foggers under the shades. Data were categorized by season of calving (spring, Feb. May; summer, June Sept.; and fall, Oct. Jan.). Traits evaluated were calving interval, days open and services/conception. Calving interval was shortest for cows calving in the spring (378 days), intermediate in fall (382 days) and longest in summer (396 days). Similar seasonal trends were observed for days open (103, 103 and 119 days, respectively) and services/conception (1.54, 1.81 and 1.93, respectively). All differences between spring and summer were significant ( P < 0.05). Calving interval and days open were less for evaporative-cooled groups (374 and 98 days, respectively), with no difference between shade only and foggers (391 and 392 days, 112 and 116 days, respectively). Services/conception were similar for all groups (1.72 to 1.79). A significant interaction between microclimate and season for services/conception could be interpreted as (i) smaller season differences for evaporative-cooled groups than for shade or foggers, or (ii) a change in the ranking of control and fogger groups during summer versus fall. Evaporative cooling was more effective than fogging for reducing the detrimental effects of seasonal high temperatures on fertility.

This paper deals with the market structure at the opening of the trading day and its influence on subsequent trading. We compare a single continuous double auction and two complement markets with different call auction designs as opening mechanisms in a unified experimental framework. The call auctions differ with respect to their levels of transparency. We find that a call auction not only improves market efficiency and liquidity at the beginning of the trading day when compared to the stand-alone continuous double auction, but also causes positive spillover effects on subsequent trading. Concerning the design of the opening call auction, we find no significant differences between the transparent and nontransparent specification with respect to opening prices and liquidity. In the course of subsequent continuous trading, however, market quality is slightly higher after a nontransparent call auction. PMID:26351653

Understanding the effects of climatic change on phenological phases of cotton (Gossypium hirsutum L.) in oasis of arid regions may help optimize management schemes to increase productivity. This study assessed the impacts of climatic changes on the phenological phases and productivity of spring cotton. The results showed that climatic warming led the dates of sowing seed, seeding emergence, three-leaf, five-leaf, budding, anthesis, full bloom, cleft boll, boll-opening, boll-opening filling, and stop-growing become earlier by 24.42, 26.19, 24.75, 23.28, 22.62, 15.75, 14.58, 5.37, 2.85, 8.04, and 2.16 days during the period of 1981-2010, respectively. The growth period lengths from sowing seed to seeding emergence and from boll-opening to boll-opening filling were shortened by 1.76 and 5.19 days, respectively. The other growth period lengths were prolonged by 2-9.71 days. The whole growth period length was prolonged by 22.26 days. The stop-growing date was delayed by 2.49-3.46 days for every 1 °C rise in minimum, maximum, and mean temperatures; however, other development dates emerged earlier by 2.17-4.76 days. Rising temperatures during the stage from seeding emergence to three-leaf reduced seed cotton yields. However, rising temperatures increased seed cotton yields in the two stages from anthesis to cleft boll and from boll-opening filling to the stop-growing. Increasing accumulated temperatures (AT) had different impacts on different development stages. During the vegetative phase, rising AT led to reduced seed cotton yields, but rising AT during reproductive stage increased seed cotton yields. In conclusion, climatic warming helpfully obtained more seed cotton yields in oasis of arid regions in northwest China. Changing the sowing date is another way to enhance yields for climate change in the future.

The results of the first study on the effects of multi-walled carbon nanotubes (MWNTs) on the exploratory activity and the emotional state in laboratory rats assessed by the open field test are reported. During three or ten days, rats received 8-10 nm MWNTs added to their food at a dose of 500 mg/kg. It was demonstrated that, in the group of rats which were fed with MWNTs, the integrated anxiety level index began to increase as early as the third day of the experiment; on the tenth day, it appeared to be twice increased. It was also demonstrated that MWNTs decreased the integrated exploratory activity index nearly twofold on the third day and nearly fourfold on the tenth day.

Emerging literature suggests superior clinical short- and long-term outcomes of MIS (minimally invasive surgery) TLIFs (transforaminal lumbar interbody fusion) versus open fusions. Few studies to date have analyzed the cost differences between the two techniques and their relationship to acute clinical outcomes. The purpose of the study was to determine the differences in hospitalization costs and payments for patients treated with primary single-level MIS versus open TLIF. The impact of clinical outcomes and their contribution to financial differences was explored as well. This study was a nonrandomized, nonblinded prospective review. Sixty-six consecutive patients undergoing a single-level TLIF (open/MIS) were analyzed (33 open, 33 MIS). Patients in either cohort (MIS/open) were matched based on race, sex, age, smoking status, medical comorbidities (Charlson Comorbidity index), payer, and diagnosis. Every patient in the study had a diagnosis of either degenerative disc disease or spondylolisthesis and stenosis. Operative time (minutes), length of stay (LOS, days), estimated blood loss (EBL, mL), anesthesia time (minutes), Visual Analog Scale (VAS) scores, and hospital cost/payment amount were assessed. The MIS and open TLIF groups were compared based on clinical outcomes measures and hospital cost/payment data using SPSS version 20.0 for statistical analysis. The two groups were compared using bivariate chi-squared analysis. Mann-Whitney tests were used for non-normal distributed data. Effect size estimate was calculated with the Cohen d statistic and the r statistic with a 95% confidence interval. Average surgical time was shorter for the MIS than the open TLIF group (115.8 minutes vs. 186.0 minutes respectively; p=.001). Length of stay was also reduced for the MIS versus the open group (2.3 days vs. 2.9 days, respectively; p=.018). Average anesthesia time and EBL were also lower in the MIS group (p<.001). VAS scores decreased for both groups, although these scores were significantly lower for the MIS group (p<.001). Financial analysis demonstrated lower total hospital direct costs (blood, imaging, implant, laboratory, pharmacy, physical therapy/occupational therapy/speech, room and board) in the MIS versus the open group ($19,512 vs. $23,550, p<.001). Implant costs were similar (p=.686) in both groups, although these accounted for about two-thirds of the hospital direct costs in the MIS cohort ($13,764) and half of these costs ($13,778) in the open group. Hospital payments were $6,248 higher for open TLIF patients compared with the MIS group (p=.267). MIS TLIF technique demonstrated significant reductions of operative time, LOS, anesthesia time, VAS scores, and EBL compared with the open technique. This reduction in perioperative parameters translated into lower total hospital costs over a 60-day perioperative period. Although hospital reimbursements appear higher in the open group over the MIS group, shorter surgical times and LOS days in the MIS technique provide opportunities for hospitals to reduce utilization of resources and to increase surgical case volume.

Potential furfural compounds were examined by RP-HPLC-DAD in 20 commercial milk-based powdered infant formula (IF) brands from local markets from Paris, France; DF, Mexico; Copenhagen, Denmark; England, UK; and Barcelona, Spain. We traced the evolution of these compounds after the packets had been opened at 0, 30 and 70 days of storage at room temperature (≈25 °C; minimum 23 °C and maximum 25.5 °C). All formula brands were analysed during the first 3-5 months of their shelf life. The mean values of all IFs for potential 5-hydroxymethyl-2-furaldehyde (HMF)+2-furaldehyde (F) were 1115.2 μg/100 g (just opened), 1157.6 μg/100 g (30 days) and 1344.5 μg/100 g of product (70 days). In general, slight increases of potential furfural contents were observed in most of the studied IFs, which suggests that the Maillard reaction increases after opening the packets. The main furfural compound found was HMF, as expected. The range of potential HMF consumed for an infant about 6 months old feeding only on formula was estimated between 0.63 mg and 3.25 mg per day.

PURPOSE We wanted to determine whether the severity and duration of illness caused by the common cold are influenced by randomized assignment to open-label pills, compared with conventional double-blind allocation to active and placebo pills, compared with no pills at all. METHODS We undertook a randomized controlled trial among a population with new-onset common cold. Study participants were allocated to 4 parallel groups: (1) those receiving no pills, (2) those blinded to placebo, (3) those blinded to echinacea, and (4) those given open-label echinacea. Primary outcomes were illness duration and area-under-the-curve global severity. Secondary outcomes included neutrophil count and interleukin 8 levels from nasal wash at intake and 2 days later. RESULTS Of 719 randomized study participants, 2 were lost and 4 exited early. Participants were 64% female, 88% white, and aged 12 to 80 years. Mean illness duration for each group was 7.03 days for those in the no-pill group, 6.87 days for those blinded to placebo, 6.34 days for those blinded to echinacea, and 6.76 days for those in the open-label echinacea group. Mean global severity scores for the 4 groups were no pills, 286; blinded to placebo, 264; blinded to echinacea, 236; and open-label echinacea, 258. Between-group differences were not statistically significant. Comparing the no-pill with blinded to placebo groups, differences (95% confidence interval [CI]) were −0.16 days (95% CI, −0.90 to 0.58 days) for illness duration and −22 severity points (95% CI, −70 to 26 points) for global severity. Comparing the group blinded to echinacea with the open-label echinacea group, differences were 0.42 days (95% CI, −0.28 to 1.12 days) and 22 severity points (95% CI, −19 to 63 points). Median change in interleukin 8 concentration and neutrophil cell count, respectively by group, were 30 pg/mL and 1 cell for the no-pill group, 39 pg/mL and 1 cell for the group binded to placebo, 58 pg/mL and 2 cells for the group blinded to echinacea, and 70 pg/mL and 1 cell for the group with open-label echinacea, also not statistically significant. Among the 120 participants who at intake rated echinacea’s effectiveness as greater than 50 on a 100-point scale for which 100 is extremely effective, illness duration was 2.58 days shorter (95% CI, −4.47 to −0.68 days) in those blinded to placebo rather than no pill, and mean global severity score was 26% lower but not significantly different (−97.0, 95% CI, −249.8 to 55.8 points). In this subgroup, neither duration nor severity differed significantly between the group blinded to echinacea and the open-label echinacea group. CONCLUSIONS Participants randomized to the no-pill group tended to have longer and more severe illnesses than those who received pills. For the subgroup who believed in echinacea and received pills, illnesses were substantively shorter and less severe, regardless of whether the pills contained echinacea. These findings support the general idea that beliefs and feelings about treatments may be important and perhaps should be taken into consideration when making medical decisions. PMID:21747102

Obstructive ureteral pathologies in adult patients are most commonly due to ureteral strictures and secondary to surgical interventions. In this study, we aimed to compare open and laparoscopic modified Lich-Gregoir ureteral reimplantation with regards to outcomes in benign ureteral pathologies in adult patients. Between December 2008 and December 2014, 32 open cases and 29 laparoscopic cases were performed as per the data retrieved from surgical databases. All laparoscopic procedures were performed in Bakirkoy Dr. Sadi Konuk Training and Research Hospital(BEAH) and all open ureteral reimplantation procedures in Kartal Dr Lutfi Kirdar Training and Research Hospital(KEAH) and Okmeydani Training and Research Hospital(OEAH). The mean operation time was significantly lower in the group of patients operated with open group (142.5 minutes versus 188.9 minutes; P< 0.0001). The mean duration of follow-up was longer in the laparoscopy group (31 versus 28 months; p< 0.0001). The mean amount of operation associated blood loss was significantly lower in patients operated laparoscopically (93.7 mL versus 214 mL; P< 0.0001). The mean VAS score obtained six hours after surgery was 6.6 ± 0.8 in open group, and 5.8 ± 0.7 in laparoscopic group (p=0.0004). The mean VAS scores measured at post-operative day 1 was 4.5 ± 0.7 in open group and 3.7 ± 0.9 in laparoscopy group. Time required to achieve the pre-operative capability of daily activities was significantly longer in open group (15 ± 1.4 days vs 11 ± 1.4 days; p< 0.0001). Despite open techniques provide shorter operation time and laparoscopic techniques require long learning curve, we think that laparoscopic techniques are superior to open ones since that they provide a better post-operative comfort and are better tolerated in terms of complications.

The study investigated the influence of selected husbandry factors on interval to resumption of post-partum cyclicity among dairy cows in urban and peri-urban Kampala. A prospective study of 85 day post-partum period of 59 dairy cows in open (n = 38) and zero grazing (n = 21) systems was conducted on 24 farms. Cows of parity 1-6 were recruited starting 15-30 days post-partum. Progesterone (P4) content in milk taken at 10-12 day intervals was analysed using ELISA. The cow P4 profiles were classified into 'normal' (< 56 days), 'delayed' (> 56 days), 'ceased' or 'prolonged' (if started < 56 days but with abnormal P4 displays) resumption of luteal activity and tested for association with husbandry and cow factors. Of the 59 cows, luteal activity in 81.4% resumed normally and in 18.6%, delayed. Only 23.7% maintained regular luteal activity, while the others had ceased (10.2%), prolonged (37.3%) or unclear luteal activity (20.3%). There were no differences between open and zero-grazed cows. Milk production was higher (p < 0.05) in zero than open grazing, in urban than peri-urban and in cows fed on brew waste (p < 0.001) compared with mill products and banana peels. Results suggest that luteal activity resumes normally in a majority of cows, although only a minority experienced continued normal cyclicity once ovulation had occurred, in the two farming systems irrespective of feed supplements or water, and that supplementing with brew waste is beneficial for milk production. © 2014 The Authors.

The impact of intraoperative ventilation on postoperative pulmonary complications is not defined. The authors aimed at determining the effectiveness of protective mechanical ventilation during open abdominal surgery on a modified Clinical Pulmonary Infection Score as primary outcome and postoperative pulmonary function. Prospective randomized, open-label, clinical trial performed in 56 patients scheduled to undergo elective open abdominal surgery lasting more than 2 h. Patients were assigned by envelopes to mechanical ventilation with tidal volume of 9 ml/kg ideal body weight and zero-positive end-expiratory pressure (standard ventilation strategy) or tidal volumes of 7 ml/kg ideal body weight, 10 cm H2O positive end-expiratory pressure, and recruitment maneuvers (protective ventilation strategy). Modified Clinical Pulmonary Infection Score, gas exchange, and pulmonary functional tests were measured preoperatively, as well as at days 1, 3, and 5 after surgery. Patients ventilated protectively showed better pulmonary functional tests up to day 5, fewer alterations on chest x-ray up to day 3 and higher arterial oxygenation in air at days 1, 3, and 5 (mmHg; mean ± SD): 77.1 ± 13.0 versus 64.9 ± 11.3 (P = 0.0006), 80.5 ± 10.1 versus 69.7 ± 9.3 (P = 0.0002), and 82.1 ± 10.7 versus 78.5 ± 21.7 (P = 0.44) respectively. The modified Clinical Pulmonary Infection Score was lower in the protective ventilation strategy at days 1 and 3. The percentage of patients in hospital at day 28 after surgery was not different between groups (7 vs. 15% respectively, P = 0.42). A protective ventilation strategy during abdominal surgery lasting more than 2 h improved respiratory function and reduced the modified Clinical Pulmonary Infection Score without affecting length of hospital stay.

The potential of tacrine in altering cognitive/behavioral function as well as in causing toxicity was evaluated in mice of 17 and 30 days of age. Cognitive and behavioral studies were performed using a step-through passive avoidance task and a habituation open-field test with a 24-h retention interval. Tacrine was subcutaneously injected (1.25-80 micro mol/kg) 30 min prior to the first session of both tests. During the training session in step-through task, tacrine treatment dose-dependently decreased the number of footshocks, with IC(50) values being 7.8 and 23.3 micro mol/kg in 17- and 30-day-old mice, respectively. Treatment with tacrine at a low dose (5 micro mol/kg) significantly prolonged the retention latency in 17-day-old mice only, but it shortened the retention latency at high doses of 20 and 40 micro mol/kg in 17- and 30-day-old, respectively. During the acquisition session in the open-field test, tacrine treatment dose-dependently decreased the locomotor activity in 17- and 30-day-old mice, with IC(50) values being 15.1 and 24.7 micro mol/kg, respectively. High doses of tacrine invariably increased the locomotor activity during the recall session. Tacrine treatment at a dose of 40 micro mol/kg caused a significant increase in serum alanine aminotransferase activity in 17- and 30-day-old mice at 6 h post-dosing, with the extent of stimulation in 30-day-old mice being more prominent. In conclusion, tacrine was more potent in enhancing/disrupting the cognitive function, inhibiting locomotor activity as well as in causing hepatotoxicity in 17-day-old than in 30-day-old mice.

Records were obtained over a 3 year period from six Holstein dairy farms of 300 to 500 cows each in the Phoenix, Ariz. area. Dairies were selected on the basis of similar management practices, herd size, milk production and facilities (with the exception of cooling systems). Microclimatic modifications (two dairies each) were shade only (approximately 3.7 m2/cow), evaporative-cooled shades and low-pressure water foggers under the shades. Data were categorized by season of calving (spring, Feb.-May; summer, June-Sept.; and fall, Oct.-Jan.). Traits evaluated were calving interval, days open and services/conception. Calving interval was shortest for cows calving in the spring (378 days), intermediate in fall (382 days) and longest in summer (396 days). Similar seasonal trends were observed for days open (103, 103 and 119 days, respectively) and services/conception (1.54, 1.81 and 1.93, respectively). All differences between spring and summer were significant (P less than 0.05). Calving interval and days open were less for evaporative-cooled groups (374 and 98 days, respectively), with no difference between shade only and foggers (391 and 392 days, 112 and 116 days, respectively). Services/conception were similar for all groups (1.72 to 1.79). A significant interaction between microclimate and season for services/conception could be interpreted as (i) smaller season differences for evaporative-cooled groups than for shade or foggers, or (ii) a change in the ranking of control and fogger groups during summer versus fall. Evaporative cooling was more effective than fogging for reducing the detrimental effects of seasonal high temperatures on fertility.

IMPORTANCE Follow-up with a primary care provider (PCP) in addition to the surgical team is routinely recommended to patients discharged after major surgery despite no clear evidence that it improves outcomes. OBJECTIVE To test whether PCP follow-up is associated with lower 30-day readmission rates after open thoracic aortic aneurysm (TAA) repair and ventral hernia repair (VHR), surgical procedures known to have a high and low risk of readmission, respectively. DESIGN, SETTING, AND PARTICIPANTS In a cohort of Medicare beneficiaries discharged to home after open TAA repair (n = 12 679) and VHR (n = 52 807) between 2003 to 2010, we compared 30-day readmission rates between patients seen and not seen by a PCP within 30 days of discharge and across tertiles of regional primary care use. We stratified our analysis by the presence of complications during the surgical (index) admission. MAIN OUTCOMES AND MEASURES Thirty-day readmission rate. RESULTS Overall, 2619 patients (20.6%) undergoing open TAA repair and 4927 patients (9.3%) undergoing VHR were readmitted within 30 days after surgery. Complications occurred in 4649 patients (36.6%) undergoing open TAA repair and 4528 patients (8.6%) undergoing VHR during their surgical admission. Early follow-up with a PCP significantly reduced the risk of readmission among open TAA patients who experienced perioperative complications, from 35.0% (without follow-up) to 20.4% (with follow-up) (P < .001). However, PCP follow-up made no significant difference in patients whose hospital course was uncomplicated (19.4% with follow-up vs 21.9% without follow-up; P = .31). In comparison, early follow-up with a PCP after VHR did not reduce the risk of readmission, regardless of complications. In adjusted regional analyses, undergoing open TAA repair in regions with high compared with low primary care use was associated with an 18% lower likelihood of 30-day readmission (odds ratio, 0.82; 95% CI, 0.71–0.96; P = .02), whereas no significant difference was found among patients after VHR. CONCLUSIONS AND RELEVANCE Follow-up with a PCP after high-risk surgery (eg, open TAA repair), especially among patients with complications, is associated with a lower risk of hospital readmission. Patients undergoing lower-risk surgery (eg, VHR) do not receive the same benefit from early PCP follow-up. Identifying high-risk surgical patients who will benefit from PCP integration during care transitions may offer a low-cost solution toward limiting readmissions. PMID:25074237

Volume-outcome relationships for open abdominal aortic aneurysm (AAA) repair have received less attention in publicly funded health systems. Furthermore, the roles of surgeon seniority (years of experience) and composite volume (encompassing all major arterial cases) on outcomes after open AAA repair are less well known. We sought to determine the effects of surgeon volume, surgeon years of experience, and composite volume on outcomes after elective open AAA repairs performed in Ontario, Canada. Using a population-based, prospectively collected health administrative database, all elective open AAA repairs occurring in the province of Ontario from 2005 to 2014 were identified. Surgeon annual volume was classified by quintiles, with the highest volume quintile acting as the reference category. Multivariable logistic regression modeling was used, adjusting for patient factors (age, sex, comorbidities, year of procedure, income) to investigate the relationship between surgeon annual volume and 30-day mortality, 30-day major complications, 30-day reoperations, 1-year mortality, and 1-year reoperations (related to index procedure). The potential effects of annual surgeon composite volume and surgeon years of experience on postoperative outcomes were also explored. A total of 7211 elective open AAA repairs performed by 101 surgeons were identified between 2005 and 2014. Most of the operations were performed by vascular surgeons (81.5%), followed by cardiac (12.1%) and general surgeons (6.1%). Median number of procedures in the lowest quintile group was 3 repairs/y, whereas the highest quintile group performed 54 repairs/y. Overall 30-day mortality was 3%. No difference in mortality was detected in comparing the lowest with the highest volume groups (1.89% vs 3.01%; adjusted odds ratio [OR], 0.60; 95% confidence interval [CI], 0.27-1.33). The lowest volume group exhibited a higher 30-day complication rate (28.0% vs 20.4%; OR, 1.54; 95% CI, 1.15-2.06) and 30-day reoperation rate (10.53% vs 6.73%; OR, 1.64; 95% CI, 1.13-2.38) compared with the highest volume group. No effect of surgeon volume on 1-year mortality or 1-year reoperation was observed. Similarly, composite volume and surgeon years of experience were not associated with postoperative outcomes. In a single-payer system with a relatively high number of open AAA repairs/surgeon per year, surgeon annual volume had no effect on postoperative mortality but was associated with lower postoperative complication and reoperation rates.

Laparoscopic colectomy for both benign and malignant disease, including inflammatory bowel disease (IBD), has recently been shown to have many advantages compared with open surgery. This study aimed to compare the effect of laparoscopic versus open subtotal colectomy (STC) for IBD on overall morbidity. A total of 99 patients undergoing STC for IBD at our institution from 2007 through 2011 were identified. Patients undergoing open STC were compared with patients undergoing laparoscopic STC. Outcomes included 30-day morbidity, conversion to laparotomy, intraoperative blood loss, operative time, admission time, late onset complications and 30-day mortality. Results are presented as median values. A total of 57 patients underwent open STC (Group 1) and 42 patients laparoscopic STC (Group 2). Group 1 comprised 26 males and 31 females, with a median age of 35 years and a body mass index (BMI) of 23.2 kg/m2. Group 2 comprised 18 males and 24 females, with a median age of 34 years and a BMI of 23.5 kg/m2. Group 2 had less morbidity (42.9% versus 75.4%, p < 0.002), reduced blood loss (100 ml versus 200 ml, p < 0.001), longer operative time (193.5 min. versus 128 min., p < 0.001), shorter length of hospital stay (six days versus 16 days, p < 0.001) than Group 1. One patient died (Group 1). There was no difference in late onset complications and no conversions to laparotomy in the laparoscopic group. Laparoscopic STC has a longer operative time, but improves short-term outcomes compared with open surgery. not relevant. not relevant.

A total laryngectomy (TL) is performed as a primary or salvage therapy for laryngeal carcinoma. Pharyngotomy closure after TL is typically performed using manual sutures. Automatic stapling devices are routinely used in thoracoabdominal surgery, but have not been widely accepted for use in pharyngotomy closure. Previously described closed stapling techniques of pharyngeal closure do not allow direct evaluation of surgical margins and are limited to endolaryngeal disease. We describe an open technique for pharyngotomy closure using a mechanical stapling device. Retrospective review. A review was conducted of 16 total laryngectomies performed from May 2008 to August 2015 utilizing an Ethicon Endopath ETS Compact-Flex 45 stapler. Sixteen patients (15 male, one female), mean age 69 years, received open TL (14 salvage, two primary) with endostapler pharyngeal closure and primary tracheoesophageal puncture (TEP). Surgical time averaged 218 minutes. Median time to swallowing was 4 days (range, 2-240 days) and mean hospital stay 6 days (range, 3-10 days). Fistula incidence was 31% (5/16) overall and 36% (5/14) in the postradiation patients. Mechanical stapling is a simple method for postlaryngectomy open pharyngotomy closure. This technique allows evaluation of margins, easy primary TEP, and the opportunity for early swallowing and shorter hospital stays. In addition, it can be performed for closure of salvage laryngectomies with rates of fistula formation similar to that found in the literature using suture closure techniques. Future studies are necessary to compare oncological results and surgical complications between the open and closed stapling techniques and to traditional suture closure. 4 Laryngoscope, 127:605-610, 2017. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

To analyse trampoline-related injuries suffered after the opening of two new trampoline parks in Christchurch. Data was collected from three 90-day periods. All trampoline-related injuries were collected from electronic documentation and coding. Those injured after both arenas opened were contacted and a semi-structured interview performed. In the 90 days after both parks opened there were 602 claims for trampoline-related injuries with 106 hospital presentations (55% male). This was a significant increase (p<0.01) from one year earlier (333 claims, 37 hospital presentations) and the 90 days prior to their opening (201 claims, 15 hospital presentations). Most injuries affected an older group of children, aged between 10-14 years (26%, n=28), compared to the other two periods (p<0.01). There was also a greater proportion of lower-limb injuries (52%, n=55) compared to the other two periods (p<0.01). Thirty-six required hospital admission, with 29 operations and an average length of stay of 2.11 days. One trampoline park allowed two or more people to use the same trampoline at the same time, and had over twice as many presentations (33%, n=35) than the other trampoline park (14%, n=15). Christchurch saw a significant increase in trampoline-related injuries after the opening of two new parks. These injuries involved an older group of children, affected predominantly the lower limbs and were more severe than those reported from the use of domestic trampolines. Consistent with past research, the trampoline park allowing multiple users had a higher proportion of presentations and more injuries requiring operative intervention.

Treatment of open abdomen following secondary peritonitis is a challenge for surgery and intensive care units (ICU). The aim of this study was to compare three different concurrent treatment strategies. Patients suffering an open abdomen following surgery for secondary peritonitis at the Department of General Surgery from 01/01 to 12/03 were investigated. Factor studied: duration of open abdomen, incidence of multi-organ failure, need for surgical revisions, length of stay (LOS) in ICU, nursing requirements (change of dressing/day), survival and integrity of abdominal wall after discharge. Treatment strategies included: open packing (OP), classic vacuum assisted (V.A.C.(R))-therapy with silicone net protection for the intestine (CV) and V.A.C.(R)-therapy with "abdominal dressing" a newly developed meshed polyvinyl wrap (AD). 21 patients were studied: 5 patients were treated with OP, 8 patients with CV and 8 patients with AD. Mean LOS was 65 (OP) vs. 53 (CV) vs. 42 (AD) days (NS), peritonitis related death was 3 (OP) vs. 1 (CV) vs. 0 (AD) (p < 0.05 Chisquare test). Median nursing effort was 4 dressings/day (OP), 0.5 (CV) and 0.5 (AD) (p < 0.005 OP vs CV, AD Kruskal-Wallis test). The "abdominal dressing"-therapy seems to be a more efficient treatment option in patients suffering from open abdomen following secondary peritonitis. A trend towards shorter ICU-LOS, lower mortality rates and reduced nursing requirements support our hypothesis.

Laparoscopic surgery has become popular during the last decade, mainly because it is associated with fewer postoperative complications than the conventional open approach. It remains unclear, however, if this benefit is observed after laparoscopic correction of perforated peptic ulcer (PPU). The goal of the present study was to evaluate whether laparoscopic closure of a PPU is as safe as conventional open correction. The study was based on a randomized controlled trial in which nine medical centers from the Netherlands participated. A total of 109 patients with symptoms of PPU and evidence of air under the diaphragm were scheduled to receive a PPU repair. After exclusion of 8 patients during the operation, outcomes were analyzed for laparotomy (n = 49) and for the laparoscopic procedure (n = 52). Operating time in the laparoscopy group was significantly longer than in the open group (75 min versus 50 min). Differences regarding postoperative dosage of opiates and the visual analog scale (VAS) for pain scoring system were in favor of the laparoscopic procedure. The VAS score on postoperative days 1, 3, and 7 was significant lower (P < 0.05) in the laparoscopic group. Complications were equally distributed. Hospital stay was also comparable: 6.5 days in the laparoscopic group versus 8.0 days in the open group (P = 0.235). Laparoscopic repair of PPU is a safe procedure compared with open repair. The results considering postoperative pain favor the laparoscopic procedure.

Retrospective multi-institutional database review. To determine if minimally invasive interbody fusion is associated with cost savings when compared with open surgery. Minimally invasive spine (MIS) surgeries are increasingly recognized as equivalent to open procedures. Although these techniques have been advocated for reducing pain, disability, and length of hospitalization, to date there has been little data demonstrating these benefits. This study analyzed inpatient hospital records from the Premier Perspective database (2002 to 2009), including patients who underwent a posterior lumbar fusion with interbody cage placement by ICD-9 code, and had implant charge codes that allowed determination if MIS pedicle screws were utilized. Exclusion criteria included a refusion surgery, deformity, >2 levels, and anterior fusion. Total costs were adjusted for covariates (age, sex, race, hospital geography and setting, payor, and comorbidities) using an analysis of covariance model. A total of 6106 patients were identified (1667 MIS and 4439 open). Length of stay (LOS) for 1-level MIS surgery averaged of 3.35 days versus 3.6 days for open surgery (P≤0.006). For 2-level MIS surgery LOS averaged of 3.4 days versus 4.03 days for open surgery (P≤0.001). Total inflation-adjusted acute hospitalization cost averaged $29,187 for 1-level MIS procedures versus $29,947 for open surgery, a nonsignificant difference (P=0.55). Total inflation-adjusted acute hospitalization cost averaged $2106 lower for 2-level MIS surgery (total costs of $33,879 for MIS vs. $35,984 for open surgery, P=0.0023). Cost savings were attributable primarily to lower room and board ($857), operating room ($359), pharmacy ($304), and laboratory ($166) costs in the MIS group. High variances in the 2-level open surgery with prolonged hospital stay also accounted for overall cost differences. This data from a large nationwide sample of hospitalizations demonstrates that MIS lumbar interbody fusion results in a statistically significant reduction in hospital LOS and a reduction in total hospital costs with 2-level surgery after adjusting for significant covariates. The majority of cost savings from MIS surgery were due to more rapid mobilization and discharge, as well as a reduction in outliers with extended hospitalizations.

Stem cells are the pluripotent cells that have the capacity to differentiate into other specialized cells. Recently, many experiments have been conducted to study the potentiality of stem cells in the tissue regeneration. We report two cases treated utilizing stem cells from human exfoliated deciduous teeth (SHED) in the management of periapical lesions in permanent teeth. Two normal human deciduous teeth from children, 7‒8 years of age, were collected to isolate stem cells. Two patients, one with periapical pathology alone and the other with periapical lesion along with an open apex in young permanent teeth, were selected for the study. After initial debridement of the root canals, homing of SHED was carried out and the access cavity was sealed using glass-ionomer cement. Clinical examination after 7 days, 30 days, 90 days, 180 days and 365 days revealed no symptoms. Closure of open apex and periapical tissue healing were observed radiographically at one-month review and maintained until 365-day review. Positive response to electric pulp testing was recorded for the treated teeth from the 3- to 12-month follow-ups. The treated cases demonstrated complete resolution of periapical radiolucency in a span of 30 days, which was faster than the conventional methods. SHED could be considred effective in treating the periapical lesions and open apex in permanent teeth. PMID:28748053

To evaluate the feasibility, safety and the effectiveness of the complex assembly of open cell nitinol stents for biliary hilar malignancy. During the 10 month period between January and October 2007, 26 consecutive patients with malignant biliary hilar obstruction underwent percutaneous insertion of open cell design nitinol stents. Four types of stent placement methods were used according to the patients' ductal anatomy of the hilum. We evaluated the technical feasibility of stent placement, complications, patient survival, and the duration of stent patency. Bilobar biliary stent placement was conducted in 26 patients with malignant biliary obstruction-T (n = 9), Y (n = 7), crisscross (n = 6) and multiple intersecting types (n = 4). Primary technical success was obtained in 24 of 26 (93%) patients. The crushing of the 1st stent during insertion of the 2nd stent occurred in two cases. Major complications occurred in 2 of 26 patients (7.7%). One case of active bleeding from hepatic segmental artery and one case of sepsis after procedure occurred. Clinical success was achieved in 21 of 24 (87.5%) patients, who were followed for a mean of 141.5 days (range 25-354 days). The mean primary stent patency period was 191.8 days and the mean patient survival period was 299 days. Applying an open cell stent in the biliary system is feasible, and can be effective, especially in multiple intersecting stent insertions in the hepatic hilum.

To analyse the outcomes of laparoscopic versus open repair for perforated peptic ulcers (PPU). All patients undergoing PPU repair between January 2002 and March 2012 were included in the study. Demographic characteristics, operation time, complications, and length of hospital stay were evaluated. Two hundred and twelve patients (median age, 49 years) were included, 60 in the laparoscopic group and 52 in the open group. Patients operated laparoscopically were significantly younger and had a higher consumption of tobacco, alcohol and cannabis. Median acute symptoms time was shorter in the laparoscopic group (6h) compared to the open group (12h; P=.025) Symptoms time was shorter in the laparoscopic group. Median operating time was significantly longer in the laparoscopic group (104.5min vs. 76min, P=.025). The percentage of conversion to open repair was 25%. There was no difference in morbidity between 2 groups, but there were 3 deaths in the open group. Median hospital stay was significantly shorter in patients treated laparoscopically when compared with the open group (6 days vs. 8 days; P=.041). Laparoscopic and open repair are equally safe in the management of PPU. A shorter hospital stay can be achieved in the laparoscopic group. Copyright © 2012 AEC. Published by Elsevier Espana.

Introduction Inguinal hernias have been treated traditionally with open methods of herniorrhaphy or hernioplasty. But the trends have changed in the last decade with the introduction of minimal access surgery. Methods This study was a prospective descriptive study in patients presenting to Surgery Department of B. P. Koirala Institute of Health Sciences, Dharan, Nepal with reducible inguinal hernias from January 2011 to June 2012. All patients >18 years of age presenting with inguinal hernias were given the choice of laparoscopic repair or open repair. Those who opted for laparoscopic repair were included in the study. Results There were 50 patients, age ranged from 18 to 71 years with 34 being median age at presentation. In 41 patients, totally extraperitoneal repair was attempted. Of these, 2 (4%) repairs were converted to transabdominal repair and 2 to open mesh repair (4%). In 9 patients, transabdominal repair was done. The median total hospital stay was 4 days (range 3-32 days), the mean postoperative stay was 3.38±3.14 days (range 2-23 days), average time taken for full ambulation postoperatively was 2.05±1.39 days (range 1-10 days), and median time taken to return for normal activity was 5 days (range 2-50 days). One patient developed recurrence (2%). None of the patients who had laparoscopic repair completed complained of neuralgias in the follow-up. Conclusion Laparoscopic repair of inguinal hernias could be contemplated safely both via totally extra peritoneal as well as transperitoneal route even in our setup of a developing country with modifications.

The goal of our study was to apply this open field test to assess sound-induced behaviors in Labrador retrievers drawn from a pool of candidate improvised explosive devices (IED)-detection dogs. Being robust to fear-inducing sounds and recovering quickly is a critical requirement of these military working dogs. This study presented male and female dogs, with 3 minutes of either ambient noise (Days 1, 3 and 5), recorded thunderstorm (Day 2), or gunfire (Day 4) sounds in an open field arena. Behavioral and physiological responses were assessed and compared to control (ambient noise) periods. An observer blinded to sound treatment analyzed video records of the 9-minute daily test sessions. Additional assessments included measurement of distance traveled (activity), heart rate, body temperature, and salivary cortisol concentrations. Overall, there was a decline in distance traveled and heart rate within each day and over the five-day test period, suggesting that dogs habituated to the open field arena. Behavioral postures and expressions were assessed using a standardized rubric to score behaviors linked to canine fear and anxiety. These fear/anxiety scores were used to evaluate changes in behaviors following exposure to a sound stressor. Compared to control periods, there was an overall increase in fear/anxiety scores during thunderstorm and gunfire sound stimuli treatment periods. Fear/anxiety scores were correlated with distance traveled, and heart rate. Fear/anxiety scores in response to thunderstorm and gunfire were correlated. Dogs showed higher fear/anxiety scores during periods after the sound stimuli compared to control periods. In general, candidate IED-detection Labrador retrievers responded to sound stimuli and recovered quickly, although dogs stratified in their response to sound stimuli. Some dogs were robust to fear/anxiety responses. The results suggest that the open field sound test may be a useful method to evaluate the suitability of dogs for IED-detection training.

Tears of the Achilles tendon in professional athletes are an infrequent yet devastating injury. Historical studies have demonstrated not only a poor rate of return to competitive play but have also noted significant declines in performance for those able to return. While classic treatment of these injuries in the competitive athlete has been an open, locked suture repair, this article reports on a consecutive series of professional football athletes who underwent mini-open repair. All athletes returned to professional football, with seven out of nine (78%) returning to National Football League (NFL) competition. Average return to play was 273 days (8.9 months), with one athlete returning at 166 days (5.4 months). There have been no reruptures and no sural nerve or wound healing complications. Although limited in number currently, mini-open repair in NFL athletes has allowed successful return to competitive play with no reruptures and a trend toward faster return to play compared with historical open repair outcomes.

Open inguinal hernia repair is one of the most painful procedures in day surgery. A continuous ambulatory analgesic is thought to reduce postoperative pain when it is applied to the surgical site. The aim of this study is to evaluate the efficacy of local anesthetic infusion pump following open inguinal hernia repair for the reduction of postoperative pain. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) that have investigated the outcomes of using an infusion pump for delivering a local anesthetic contrasted to a control group for open inguinal hernia repair. Pain was assessed from Day 1 to Day 5 following the surgery. The secondary outcomes included analgesia use and postoperative complications. We reviewed 5 trials that totaled 288 patients. The analgesic effects of bupivacaine (4 trials) and ropivacaine (one trial) were compared with a placebo group. The pooled mean difference in the score measuring the degree of pain diminished significantly at Day 1 to Day 4 in the experimental group. Two studies have reported that the number of analgesics required also decreased in the experimental group. No bupivacaine-related complication was reported. Our results revealed that applying a local anesthetic infusion pump following inguinal hernia repairs was more efficacious for reducing postoperative pain than a placebo. However, the findings were based on a small body of evidence in which methodological quality was not high. The potential benefits of applying a local anesthetic infusion pump to hernia repair must still be adequately investigated using further RCTs. Copyright © 2014 Surgical Associates Ltd.

Young adults with Down syndrome experience increased rates of emotional and behavioural problems compared with the general population. Most adolescents with Down syndrome living in Western Australia participate in sheltered employment as their main day occupation. Relationship between day occupation and changes in behaviour has not been examined. Therefore, the aim of this research was to explore any relationship between post school day occupations and changes in the young person's behaviour. The Down syndrome Needs Opinion Wishes database was used for case ascertainment of young adults aged 15 to 32 years with Down syndrome. Families of 118 young people in this population-based database completed questionnaires in 2004, 2009 and 2011. The questionnaires addressed both young person characteristics such as age, gender, presence of impairments, behaviour, functioning in activities of daily living, and family characteristics such as income and family functioning. Post-school day occupations in which the young people were participating included open and sheltered employment, training and day recreation programs. Change in behaviour of young adults who remained in the same post-school day occupation from 2009 to 2011 (n = 103) were examined in a linear regression model adjusting for confounding variables including age, gender, prior functioning and behaviour in 2004 and family income. In comparison to those young adults attending open employment from 2009 to 2011, those attending day recreation programs were reported to experience worsening in behaviour both in the unadjusted (effect size -0.14, 95% CI -0.24, -0.05) and adjusted models (effect size -0.15, 95% CI -0.29, -0.01). We found that the behaviour of those participating in open employment improved compared to those attending other day occupations. Further examination of the direction of this association is required.

To describe the sequelae of oral endotracheal intubation by evaluating prevalence rates of structural injury, hyposalivation, and impaired vocal production over 14days following extubation. Consecutive adults (≥20years, N=114) with prolonged (≥48h) endotracheal intubation were enrolled from medical intensive care units at a university hospital. Participants were assessed by trained nurses at 2, 7, and 14days after extubation, using a standardized bedside screening protocol. Within 48-hour postextubation, structural injuries were common, with 51% having restricted mouth opening. Unstimulated salivary flow was reduced in 43%. For vocal production, 51% had inadequate breathing support for phonation, dysphonia was common (94% had hoarseness and 36% showed reduced efficiency of vocal fold closure), and >40% had impaired articulatory precision. By 14days postextubation, recovery was noted in most conditions, but reduced efficiency of vocal fold closure persisted. Restricted mouth opening (39%) and reduced salivary flow (34%) remained highly prevalent. After extubation, restricted mouth opening, reduced salivary flow, and dysphonia were common and prolonged in recovery. Reduced efficiency of vocal cord closure persisted at 14days postextubation. The extent and duration of these sequelae remind clinicians to screen for them up to 2weeks after extubation. Copyright © 2017 Elsevier Inc. All rights reserved.

Need and feasibility of telemedicine in non-urban day care centres.

PubMed

Setia, Monika; DelliFraine, Jami L

2010-01-01

There appear to have been no studies of telemedicine in rural day care centres. We have assessed the feasibility of using telemedicine in eight rural day care centres in Pennsylvania, from the day care centres' perspective. The average number of children in these centres was 76 (range 20-150). The centres sent an average of 4.7 children home each month because of illness. Using telephone and face-to-face interviews, we assessed their perceived need for and familiarity with telemedicine, as well as their openness and preparedness for implementing telemedicine. Most day care centres reported a need for telemedicine and were open to learning how to use it. Some centres were concerned about adequate space for the equipment, but overall, the centres felt that their resources were adequate. Telemedicine in rural day care centres appears to be feasible, and would have the potential to save time and money for parents, as well as perhaps improving health care for children in rural areas.

Objectives Bursitis of the olecranon and the patella are not rare disorders, and conservative management is successful in most cases. However, when patients do not respond to conservative treatment, open excisional surgery or, recently, endoscopic bursectomy, can be used. The aim of this study was to evaluate the results of open and endoscopic treatments of olecranon and prepatellar bursitis. Patients and methods Forty-nine patients (37 male and 12 female), who were treated with endoscopic bursectomy (25 patients) or open bursectomy (24 patients) were included in this study. Thirty patients had olecranon bursitis, while 19 patients had prepatellar bursitis. The patients’ average age was 61.1 ± 12.3 (range 33-81) years. All of the patients’ hospitalization and surgery times were recorded. The satisfaction of the patients was evaluated with a satisfaction scoring system, as well as by evaluating residual pain, the range of joint movement, and the cosmetic results of the procedure. Results The average follow-up time was 16 ± 9 months (range 12–27). The median operation time was 23.2 ± 3.5 minutes for the endoscopic bursectomy group and 26.4 ± 6.8 minutes for the open bursectomy group. The median hospitalization time was 0.56 ± 0.5 days (range 0-1 day) for the endoscopic group and 1 ± 0 days for the open bursectomy group (P<0.01). According to the patient satisfaction questionnaire, the endoscopic bursectomy group’s score was 8.5 ± 1.3 (range 5-10), and the open bursectomy group’s score was 5.29 ± 1.8 (range 1-9) (P<0.01). Conclusion Endoscopic bursectomy is a time-saving and efficient surgical treatment option for patients with prepatellar and olecranon bursitis. PMID:29805943

Open reduction of nasal bone fractures through an intercartilaginous incision.

2013-01-01

Open reduction through an intercartilaginous incision was useful for treating delayed-diagnosed nasal bone fractures because it resulted in a successful outcome with minimal complications. Nasal bone fractures are generally managed with closed reduction, which is usually inadequate and results in airway obstruction with a delayed diagnosis of nasal bone fracture when bone healing and fibrotic adhesions around the bone fragment have progressed. This study investigated the surgical outcome of open reduction through an intercartilaginous incision for delayed-diagnosis nasal bone fractures. The study enrolled 18 patients who underwent open reduction through an intercartilaginous incision to correct delayed-diagnosis nasal bone fractures. Three independent otorhinolaryngologists evaluated the outcomes 4-35 months (average 12.7 months) postoperatively as excellent, fair or poor. The time from injury to surgery was 11-39 days (20-39 days in adults and 11-30 days in children). The 18 cases included 16 primary repairs and two revisions. A Kirschner wire was inserted in six (33.3%) patients who had unstable reduced nasal bones. Postoperatively, l5 (83%) patients had excellent results, two (11%) had fair, and one (6%) had a poor outcome. No patient experienced any complication.

The purpose of this study was to review surgical outcomes after elective placement of peritoneal dialysis (PD) catheters in children with end-stage renal disease. Children with PD catheters placed between February 2002 and July 2014 were retrospectively reviewed. Outcomes were catheter life, late (>30days post-op) complications (catheter malfunction, catheter malposition, infection), and re-operation rates. Comparison groups included laparoscopic versus open placement, age<2, and weight<10kg. Univariate and multivariate analysis were performed. One hundred sixteen patients had 173 catheters placed (122 open, 51 laparoscopic) with an average patient age of 9.7±6.3years. Mean catheter life was similar in the laparoscopic and open groups (581±539days versus 574±487days, p=0.938). The late complication rate was higher for open procedures (57% versus 37%, p=0.013). Children age<2 or weight<10kg had higher re-operation rates (64% versus 42%, p=0.014 and 73% versus 40%, p=0.001, respectively). Adjusted for age and weight, open technique remained a risk factor for late complications (OR 2.44, 95% CI 1.20-4.95) but not re-operation. Laparoscopic placement appears to reduce the rate of late complications in children who require PD dialysis catheters. Children <2years age or <10kg remain at risk for complications regardless of technique. Copyright © 2016 Elsevier Inc. All rights reserved.

Laying hen movement in a commercial aviary: Enclosure to floor and back again.

PubMed

Campbell, D L M; Makagon, M M; Swanson, J C; Siegford, J M

2016-01-01

Many producers in the laying hen industry, including in North America, are phasing out conventional cages in response to consumer demands and sometimes subsequent legislation. Alternative housing systems such as aviaries are being implemented in an attempt to improve hen welfare. Aviaries provide additional space and resources to groups of hens, including a litter area on the floor. However, little is known about hen movement between tiered enclosures and floor litter areas in aviary systems. Diurnal rhythms and social attraction may result in peak times of movement that could lead to overcrowding of areas, or alternatively hen preferences may lead to some areas not being fully utilized. We monitored hen movement between tiered enclosures and litter areas, including movement on and off the outer perch, across the day at peak, mid and end of lay in a commercial aviary. Hens moved onto and off of the open litter area across the day, transitioning between tiered enclosures, outer perches, open litter areas, and litter areas under tiered enclosures. At certain times of day, there were periods of greater hen movement down to the open litter area and between litter areas. For example, more hens were typically observed exiting enclosures, jumping from perches to open litter, and traveling between open litter and litter under tiered enclosures in the morning (all P ≤ 0.001). In all but one instance, more hens were observed on open litter areas in the afternoon than at other times of day (all P ≤ 0.029). However, hen re-entry to tiered enclosures showed less circadian patterning. Hen movement was observed between areas of interest at all sampled time periods, indicating hens use all areas of the system. Further research should examine whether all individual hens do move between areas equally, including within levels of the tiered enclosure, or if crowding occurs on the outer perches or in the litter during times of peak movement. © 2015 Poultry Science Association Inc.

Response of respiration and nutrient availability to drying and rewetting in soil from a semi-arid woodland depends on vegetation patch and a recent wild fire

NASA Astrophysics Data System (ADS)

Sun, Q.; Meyer, W. S.; Koerber, G.; Marschner, P.

2015-06-01

Semi-arid woodlands, which are characterised by patchy vegetation interspersed with bare, open areas, are frequently exposed to wild fire. During summer, long dry periods are occasionally interrupted by rainfall events. It is well-known that rewetting of dry soil induces a flush of respiration. However, the magnitude of the flush may differ between vegetation patches and open areas because of different organic matter content which could be further modulated by wild fire. Soils were collected from under trees, under shrubs or in open areas in unburnt and burnt sandy Mallee woodland, where part of the woodland experienced a wild fire which destroyed or damaged most of the aboveground plant parts four months before sampling. In an incubation experiment, the soils were exposed to two moisture treatments: constantly moist (CM) and drying and rewetting (DRW). In CM, soils were incubated at 80% of maximum water holding capacity for 19 days; In DRW, soils were dried for four days, kept dry for another five days, then rewet to 80% WHC and maintained at this water content until day 19. Soil respiration decreased during drying and was very low in the dry period; rewetting induced a respiration flush. Compared to soil under shrubs and in open areas, cumulative respiration per g soil in CM and DRW was greater under trees, but lower when expressed per g TOC. Organic matter content, available P, and microbial biomass C, but not available N were greater under trees than in open areas. Wild fire decreased the flush of respiration per g TOC in the open areas and under shrubs, and reduced TOC and MBC concentrations only under trees, but had little effect on available N and P concentrations. We conclude that of the impact wild fire and DRW events on nutrient cycling differ among vegetation patches of a native semiarid woodland which is related to organic matter amount and availability.

The benefits of donor human milk compared with artificial formulas have been well demonstrated; nevertheless the impact in the clinical practice of opening a human milk bank within a neonatal unit has not yet been studied. The main aim of this study was to analyze the impact on the clinical practice of opening a human milk bank in a neonatal unit to provide donor human milk for preterm infants ≤ 32 weeks of gestational age. A before and after study was designed, with the intervention being the opening a human milk bank. Preterm infants ≤ 32 weeks of gestational age born in the Hospital 12 Octubre from July to December 2005 and January to June 2008 (firsts 6 months after opening the human milk bank) were included. After opening the human milk bank, enteral feedings were started 31h before (P<.001), 100ml/kg/day were achieved 59.5h before (P<.001) and 150 ml/kg/day 52 h before (P=.002). Enteral feedings were never started LM with artificial formula, the exposure to formula in the first 15 days of life was reduced from 50% to 16.6%, and it's consumption during the first 28 days of life was significantly reduced. There was a higher consumption of own mother's milk during the hospital stay, and a higher rate of exclusive breastfeeding at hospital discharge (54% vs 40%). The availability of donor human milk has led to quicker progression with enteral feedings and earlier withdrawal of parenteral nutrition. It has reduced the exposure to artificial formulas, and has also increased the intake of own mother's milk during the hospital stay and the rate of exclusive breastfeeding at hospital discharge.

The aim of this study was to compare the early postoperative outcome of patients undergoing laparoscopic subtotal colectomy with those undergoing open subtotal colectomy for colitis refractory to medical treatment. A retrospective observational study was carried out of patients who underwent subtotal colectomy for refractory colitis, at a single centre, between 2006 and 2012. Patients were matched for age, gender, American Society of Anesthesiology (ASA) grade, urgency of operation and immunosuppressant/modulator treatment. The primary outcome measure was the number of postoperative complications, classified using the Clavien-Dindo scale. Secondary end-points included procedure duration, laparoscopic conversion rates, blood loss, 30-day readmission rates and length of hospital stay. Ninety-six patients were included, 39 of whom had laparoscopic surgery. Thirty-two of these were matched to similar patients who underwent an open procedure. The overall duration of the procedure was longer for laparoscopic surgery than for open surgery (median: 240 vs 150 min, P < 0.005) but estimated blood loss was less (median: 75 vs 400 ml, P < 0.005). In the laparoscopic group, 23 patients experienced 27 complications, and in the open surgery group, 23 patients experienced 30 complications. Most complications were minor (Grade I/II), and the distribution of complications, by grade, was similar between the two groups. There was no statistically significant difference in 30-day readmission rates between the laparoscopic and open groups (five readmissions vs eight readmissions, P = 0.536). Length of hospital stay was 4 days shorter for laparoscopic surgery, but this difference was not statistically significant (median: 7 vs 11 days, P = 0.159). In patients requiring colectomy for acute severe colitis, laparoscopic surgery reduced blood loss but increased operating time and was not associated with a reduction in early postoperative complications, length of hospital stay or readmission rates.

We sought to compare the contemporary rates of short-term complications of open versus laparoscopic renal and ureteral surgery in pediatric patients. A retrospective cross-sectional analysis of the National Surgical Quality Improvement Program Pediatrics database was performed of all cases in 2014 identified using CPT procedure codes for nephrectomy, partial nephrectomy (PN), ureteroneocystostomy (UNC), and pyeloplasty, and reviewed for postoperative complications. Univariate analysis was performed to determine 30-day complications, with comparison between open and MIS approaches. Receiver operator curve (ROC) analysis was performed to determine differences in body surface area (BSA) and age for open versus MIS. Review identified 207 nephrectomies, 72 PN, 920 UNC, and 625 pyeloplasties. MIS was associated with older age and larger BSA except for cases of UNC. Apart from PN, operative durations were longer with MIS. However, only PN was associated with significantly longer length of hospital stay (LOS). There was no difference in incidence of all other 30-day complications. When evaluating BSA via ROC, the area under the curve (AUC) was found to be 0.730 and was significant. Children with a BSA greater than 0.408 m 2 were more likely to have MIS (sensitivity, 66.9%; specificity, 69.3%). Regarding age, the AUC was 0.732. Children older than 637.5 days were more likely to have MIS (sensitivity, 72.8%; specificity, 63.3%). Pediatric MIS is associated with longer operative time for nephrectomy, but shorter LOS following PN. Surgical approach was not associated with difference in short-term complications.

To determine the effects on weight gain and temperature control of transferring preterm infants from incubators to open cots at a weight of 1600 g versus a weight of 1800 g. Randomised controlled trial. One tertiary and two regional neonatal units in public hospitals in Queensland, Australia. 182 preterm infants born with a birth weight less than 1600 g, who were at least 48 h old; had not required ventilation or continuous positive airways pressure within the last 48 h; were medically stable with no oxygen requirement, or significant apnoea or bradycardia; did not require phototherapy; and were enterally fed with an intake (breast milk/formula) of at least 60 ml/kg/day. Transfer into an open cot at 1600 or 1800 g. The primary outcomes were temperature stability and average daily weight gain over the first 14 days following transfer to an open cot. 90 infants in the 1600 g group and 92 infants in the 1800 g group were included in the analysis. Over the first 72 h, more infants in the 1800 g group had temperatures <36.4°C than the 1600 g group (p=0.03). From post-transfer to discharge, the 1600 g group had more temperatures >37.1°C (p=0.02). Average daily weight gain in the 1600 g group was 17.07 (SD±4.5) g/kg/day and in the 1800 g group, 13.97 (SD±4.7) g/kg/day (p=<0.001). Medically stable, preterm infants can be transferred to open cots at a birth weight of 1600 g without any significant adverse effects on temperature stability or weight gain.

Infection of open fractures remains a significant cause of morbidity and mortality to patients worldwide. Early administration of prophylactic antibiotics is known to improve outcomes; however, increasing concern regarding antimicrobial resistance makes finding new compounds for use in such cases a pressing area for further research. CSA-90, a synthetic peptidomimetic compound, has previously demonstrated promising antimicrobial action against Staphylococcus aureus in rat open fractures. However, its efficacy against antibiotic-resistant microorganisms, its potential as a therapeutic agent in addition to its prophylactic effects, and its proosteogenic properties all require further investigation. (1) Does prophylactic treatment with CSA-90 reduce infection rates in a rat open fracture model inoculated with S aureus, methicillin-resistant S aureus (MRSA), and methicillin-resistant Staphylococcus epidermidis (MRSE) as measured by survival, radiographic union, and deep tissue swab cultures? (2) Does CSA-90 reduce infection rates when administered later in the management of an open fracture as measured by survival, radiographic union, and deep tissue swab cultures? (3) Does CSA-90 demonstrate a synergistic proosteogenic effect with bone morphogenetic protein 2 (BMP-2) in a noninfected rat ectopic bone formation assay as assessed by micro-CT bone volume measurement? (4) Can CSA-90 elute and retain its antimicrobial efficacy in vitro when delivered using clinically relevant agents measured using a Kirby-Bauer disc diffusion assay? All in vivo studies were approved by the local animal ethics committee. In the open fracture studies, 12-week-old male Wistar rats underwent open midshaft femoral fractures stabilized with a 1.1-mm Kirschner wire and 10 µg BMP-2 ± 500 µg CSA-90 was applied to the fracture site using a collagen sponge along with 1 x 10 colony-forming units of bacteria (S aureus/MRSA/MRSE; n = 10 per group). In the delayed treatment study, débridement and treatment with 500 µg CSA-90 were performed at Day 1 and Day 5 after injury and bacterial insult (S aureus). All animals were reviewed daily for signs of local infection and/or sepsis. An independent, blinded veterinarian reviewed twice-weekly radiographs, and rats showing osteolysis and/or declining overall health were culled at his instruction. The primary outcome of both fracture studies was fracture infection, incorporating survival, radiographic union, and deep tissue swab cultures. For the ectopic bone formation assay, 0 to 10 µg BMP-2 and 0 to 500 µg CSA-90 were delivered on a collagen sponge into bilateral quadriceps muscle pouches of 8-week-old rats (n = 10 per group). Micro-CT quantification of bone volume and descriptive histologic analysis were performed for all in vivo studies. Modified Kirby-Bauer disc diffusion assays were used to quantify antimicrobial activity in vitro using four different delivery methods, including bone cement. Infection was observed in none of the MRSA inoculated open fractures treated with CSA-90 with 10 of 10 deep tissue swab cultures negative at the time of cull. Median survival was 43 days (range, 11-43 days) in the treated group versus 11 days (range, 8-11 days) in the untreated MRSA inoculated group (p < 0.001). However, delayed débridement and treatment of open fractures with CSA-90 at either Day 1 or Day 5 did not prevent infection, resulting in early culls by Day 21 with positive swab cultures (10 of 10 for each time point). Maximal ectopic bone formation was achieved with 500 μg CSA-90 and 10 μg BMP-2 (mean volume, 9.58 mm; SD, 7.83), creating larger bone nodules than formed with 250 μg CSA-90 and 10 μg BMP-2 (mean volume, 1.7 mm; SD, 1.07; p < 0.001). Disc diffusion assays showed that CSA-90 could successfully elute from four potential delivery agents including calcium sulphate (mean zone of inhibition, 11.35 mm; SD, 0.957) and bone cement (mean, 4.67 mm; SD, 0.516). CSA-90 shows antimicrobial action against antibiotic-resistant Staphylococcal strains in vitro and in an in vivo model of open fracture infection. The antimicrobial properties of CSA-90 combined with further evidence of its proosteogenic potential make it a promising compound to develop further for orthopaedic applications.

An 80-year-old woman with Parkinson's disease was scheduled for open heart surgery to repair thoracic aortic aneurysm. Parkinson's symptoms were normally treated using oral levodopa (200 mg), selegiline-hydrochloride (5 mg), bromocriptine-mesilate (2 mg), and amantadine-hydrochloride (200 mg) daily. On the day before surgery, levodopa 50mg was infused intravenously. Another 25 mg of levodopa was infused immediately after surgery. Twenty hours later, the patient developed tremors, heyperventilation, but no obvious muscle rigidity. Two days after surgery, the patient exhibited high fever, hydropoiesis, elevated creatine kinase, and a rise in blood leukocytes. She was diagnosed with neuroleptic malignant syndrome. She was intubated, and received dantrolene sodium. Symptoms of neuroleptic malignant syndrome disappeared on the fourth postoperative day. The stress of open heart surgery, specifically extracorporeal circulation and concomitant dilution of levodopa, triggered neuroleptic malignant syndrome in this patient. Parkinson's patients require higher doses of levodopa prior to surgery to compensate and prevent neuroleptic malignant syndrome after surgery.

Two hundred and twelve Holstein and Jersey cows were in a study to determine factors that affected reproductive traits. First ovulation occurred about 3 wk postpartum, and interval to first ovulation was greater in cows that had clinical abnormalities postpartum than in normal cows. Jerseys producing more milk ovulated sooner postpartum than lower producing herdmates. Involution of cervix and uterus occurred later postpartum in cows that had clinical problems postpartum. Involution of genital tract occurred later postpartum in older cows and sooner postpartum in cows that had higher milk yields. Duration of first postpartum estrous cycle was 4 days less than for second postpartum cycle. Percentages of estrous cycles detected by standing estrus were 43 and 73% for Holsteins and Jerseys. Estrous detection rates were highest for cows that produced slightly above the mean milk yield and did not differ between cows in highest and lowest milk production quartiles. First detected estrus and days to first insemination occurred later postpartum in Holsteins as milk yield deviation from herdmates increased, regardless of sign. In Jerseys, days to first insemination and days open increased linearly as milk yield increased. Days to first insemination and conception were greater in cows with postpartum clinical problems. Conception rate at first insemination postpartum increased in proportion to concentration of progesterone in blood samples collected during 12 days before first insemination. Overall, clinical problems at parturition and postpartum lowered reproductive performance in both breeds. There was a slight antagonism between milk yield and reproductive performance (days open) in Jerseys but not in Holsteins.

To compare the timing of soft-tissue (flap) coverage and occurrence of complications before and after the establishment of an integrated orthopaedic trauma/microsurgical team. Retrospective cohort study. A single level 1 trauma center. Twenty-eight subjects (13 pre- and 15 post-integration) with open tibia shaft fractures (OTA/AO 42A, 42B, and 42C) treated with flap coverage between January 2009 and March 2015. Flap coverage for open tibia shaft fractures treated before ("preintegration") and after ("postintegration") implementation of an integrated orthopaedic trauma/microsurgical team. Time from index injury to flap coverage. The unadjusted median time to coverage was 7 days (95% confidence interval, 5.9-8.1) preintegration, and 6 days (95% confidence interval, 4.6-7.4) postintegration (P = 0.48). For preintegration, 9 (69%) of the patients experienced complications, compared with 7 (47%) postintegration (P = 0.23). After formation of an integrated orthopaedic trauma/microsurgery team, we observed a 1-day decrease in median days to coverage from index injury. Complications overall were lowered in the postintegration group, although statistically insignificant. Therapeutic Level III.

Major abdominal surgery (MAS) is high-risk intervention usually accompanied by tissue injury leading to a release of signaling danger molecules called alarmins. This study evaluates the surgical injury caused by two fundamental types of gastrointestinal surgical procedures (open surgery and laparoscopy) in relation to the inflammation elicited by alarmins. Patients undergoing MAS were divided into a mixed laparoscopy group (LPS) and an open surgery group (LPT). Serum levels of alarmins (S100A8, S100A12, HMGB1, and HSP70) and biomarkers (leukocytes, C-reactive protein [CRP], and interleukin-6 [IL-6]) were analyzed between the groups. The secondary objectives were to compare LPT and LPS cancer subgroups and to find the relationship between procedure and outcome (intensive care unit length of stay [ICU-LOS] and hospital length of stay [H-LOS]). A total of 82 patients were analyzed. No significant difference was found in alarmin levels between the mixed LPS and LPT groups. IL-6 was higher in the LPS group on day 2 ( p =0.03) and day 3 ( p =0.04). Significantly higher S100A8 protein levels on day 1 ( p =0.02) and day 2 ( p =0.01) and higher S100A12 protein levels on day 2 ( p =0.03) were obtained in the LPS cancer subgroup. ICU-LOS and H-LOS were longer in the LPS cancer subgroup. The degree of surgical injury elicited by open MAS as reflected by alarmins is similar to that of laparoscopic procedures. Nevertheless, an early biomarker of inflammation (IL-6) was higher in the laparoscopy group, suggesting a greater inflammatory response. Moreover, the levels of S100A8 and S100A12 were higher with a longer ICU-LOS and H-LOS in the LPS cancer subgroup.

Recently, fatty acids have been shown to modulate sensory function in animal models of neuropathic pain. In this study, the antinociceptive effect of 2-hydroxyoleic acid (2-OHOA) was assessed following spared nerve injury (SNI) with reflex and cerebrally mediated behavioural responses. Initial antinociceptive behavioural screening of daily administration of 2-OHOA (400 mg/kg, p.o.) was assessed in Wistar rats by measuring hindlimb reflex hypersensitivity to von Frey and thermal plate stimulation up to 7 days after SNI, while its modulatory effect on lumbar spinal dorsal horn microglia reactivity was assessed with OX-42 immunohistochemistry. In vitro the effect of 2-OHOA (120 μM) on cyclooxygenase protein expression (COX-2/COX-1 ratio) in lipopolysaccharide-activated macrophage cells was tested with Western blot analysis. Finally, the effects of 2-OHOA treatment on the place escape aversion paradigm (PEAP) and the open-field-induced anxiety test were tested at 21 days following nerve injury compared with vehicle-treated sham and pregabalin-SNI (30 mg/kg, p.o.) control groups. Oral 2-OHOA significantly reduced ipsilateral mechanical and thermal hypersensitivity up to 7 days after SNI. Additionally 2-OHOA decreased the COX-2/COX-1 ratio in lipopolysaccharide-activated macrophage cells and OX-42 expression within the ipsilateral lumbar spinal dorsal horn 7 days after SNI. 2-OHOA significantly restored inner-zone exploration in the open-field test compared with the vehicle-treated sham group at 21 days after SNI. Oral administration of the modified omega 9 fatty acid, 2-OHOA, mediates antinociception and prevents open-field-induced anxiety in the SNI model in Wistar rats, which is mediated by an inhibition of spinal dorsal horn microglia activation. © 2014 European Pain Federation - EFIC®

Different results have been reported concerning the postoperative outcomes of different surgical approaches for hemorrhoids. We aimed to determine the postoperative outcome following 3 main surgical techniques. A prospective, randomized trial was designed with 180 patients in 3 arms of 60 patients each. The study was conducted from April 1999 to January 2007 at the University Hospital "Campus Bio-Medico di Roma." All of the patients who were referred for hemorrhoid surgery were enrolled according to inclusion and exclusion criteria (ISRCTN12040297). Treatments according to the open, semiclosed, and stapled techniques were compared. Sample size was calculated to determine a difference in terms of the intensity of postoperative pain at the first week and the days required for return to work activity. After 1 week, patients who underwent semiclosed hemorrhoidectomy reported significantly less pain (p < 0.01) and a significant decrease in analgesic intake from the third postoperative day (p < 0.01) than after the other 2 techniques. The patients resumed work ≈11 days after semiclosed and stapled techniques (11.8 and 11.6 days), which was earlier compared with 21.3 days in the open group (p < 0.05). The high number of patients excluded might be considered a limitation of the study, but our selection criteria including patients living within 50 km of the hospital allowed for a low rate (9.4%) of patients lost to follow-up. This study found an earlier resumption of work and less pain in patients who underwent the stapled and semiclosed procedures rather than open, which was associated with more complications, particularly because of a higher rate of stenosis (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A196).

To estimate the relationship between heat stress during the last 60 days prepartum, body condition score and certain reproductive traits in the subsequent lactation of Holstein cows, 564 multiparous cows and 290 primiparous cows from four dairy herds were used in a hot, humid region. Maximum prepartum degree days were estimated to quantify the degree of heat stress. Multiple regressions analyses and logistic regression analysis were performed to determine the effect of prepartum heat stress and body condition change on reproductive parameters, which were obtained from DHIA forms at the end of the lactation. Multiparous and primiparous cows which gained body condition score from calving to 60 d postpartum exhibited 28 and 27 fewer days open (P < 0.05), respectively, than cows not gaining. There was no effect (P > 0.05) of heat stress measurement on days open or services per conception in either multiparous or primiparous cows. During hotter months of calving, multiparous cows showed higher services per conception and primiparous cows showed higher days open and services per conception (P < 0.05). Maximum prepartum degree-days were positively associated (P < 0.05) with calving difficulty score. Multiparous cows with high body condition score at calving were 1.47 times more likely to present a very difficult calving than cows that calved in October (P < 0.05). Collectively, these results suggest that reproductive performance was not affected by cumulative prepartum heat stress although it was associated with very difficult calving score.

Evidence for benefit of endovascular aneurysm repair (EVAR) over open surgical repair for de novo infrarenal abdominal aortic aneurysms (AAAs) in younger patients remains conflicting because of heterogeneous study populations and small sample sizes. The objective of this study was to compare perioperative and short-term outcomes for EVAR and open surgery in younger patients using a large national disease and procedure-specific data set. We identified patients 65 years of age or younger undergoing first-time elective EVAR or open AAA repair from the Vascular Quality Initiative (2003-2014). We excluded patients with pararenal or thoracoabdominal aneurysms, those medically unfit for open repair, and those undergoing EVAR for isolated iliac aneurysms. Clinical and procedural characteristics were balanced using inverse propensity of treatment weighting. A supplemental analysis extended the study to those younger than 70 years. We identified 2641 patients, 73% (n = 1928) EVAR and 27% (n = 713) open repair. The median age was 62 years (interquartile range, 59-64 years), and 13% were female. The median follow-up time was 401 days (interquartile range, 357-459 days). Unadjusted perioperative survival was 99.6% overall (open repair, 99.1%; EVAR, 99.8%; P < .001), with 97.4% 1-year survival overall (open repair, 97.3%; EVAR, 97.4%; P = .9). Unadjusted reintervention rates were five (open repair) and seven (EVAR) reinterventions per 100 person-years (P = .8). After propensity weighting, the absolute incidence of perioperative mortality was <1% in both groups (open repair, 0.9%, EVAR, 0.2%; P < .001), and complication rates were low. Propensity-weighted survival (hazard ratio, 0.88; 95% confidence interval, 0.56-1.38; P = .6) and reintervention rates (open repair, 6; EVAR, 8; reinterventions per 100 person-years; P = .8) did not differ between the two interventions. The analysis of those younger than 70 years showed similar results. In this study of younger patients undergoing repair of infrarenal AAA, 30-day morbidity and mortality for both open surgery and EVAR are low, and the absolute mortality difference is small. The prior published perioperative mortality and 1-year survival benefit of EVAR over open AAA repair is not observed in younger patients. Further studies of long-term durability are needed to guide decision-making for open repair vs EVAR in this population. Copyright © 2017 Society for Vascular Surgery. Published by Elsevier Inc.

Twenty-four women divided into three groups: control, exercise and nutrition, have been involved in a -6 degrees head down bed rest (HDBR) experiment for 60 days. The objective was to analyse the effects of microgravity on balance function regulation. Group comparisons assessed the efficiency of countermeasures (specific exercises and in particular diet) on the deleterious effects of simulated microgravity. Measurements of orthostatic and dynamic balance were taken 9 and 2 days prior to the experiment, on the first day of getting up, the following day and 4 and 10 days after, under two visual conditions: eyes open and eyes closed. The results confirmed that, as in any other test performed with ordinary subjects, the postural balance performances are better with eyes open than with eyes closed. The static and dynamic postural performances were impaired on the first day of recovery (R0) following HDBR. This impairment lasted up to 4 days after getting up and, afterwards the volunteers recovered their initial performances. The exercise group recovered static postural performances more quickly than the other groups whereas there were no differences in the recovery of the dynamic balance performances.

Objective To evaluate the efficacy and tolerability of single pulse transcranial magnetic stimulation (sTMS) for the preventive treatment of migraine. Background sTMS was originally developed for the acute treatment of migraine with aura. Open label experience has suggested a preventive benefit. The objective of this trial was to evaluate the efficacy and tolerability of sTMS for migraine prevention. Methods The eNeura SpringTMS Post-Market Observational U.S. Study of Migraine (ESPOUSE) Study was a multicenter, prospective, open label, observational study. From December 2014 to March 2016, patients with migraine (n = 263) were consented to complete a 1-month baseline headache diary followed by 3 months of treatment. The treatment protocol consisted of preventive (four pulses twice daily) and acute (three pulses repeated up to three times for each attack) treatment. Patients reported daily headache status, medication use, and device use with a monthly headache diary. The primary endpoint, mean reduction of headache days compared to baseline, was measured over the 28-day period during weeks 9 to 12. The primary endpoint was compared to a statistically-derived placebo estimate (performance goal). Secondary endpoints included: 50% responder rate, acute headache medication consumption, HIT-6, and mean reduction in total headache days from baseline of any intensity. Results Of a total of 263 consented subjects, 229 completed a baseline diary, and 220 were found to be eligible based on the number of headache days. The device was assigned to 217 subjects (Safety Data Set) and 132 were included in the intention to treat Full Analysis Set. For the primary endpoint, there was a -2.75 ± 0.40 mean reduction of headache days from baseline (9.06 days) compared to the performance goal (-0.63 days) ( p < 0.0001). The 50% responder rate of 46% (95% CI 37%, 56%) was also significantly higher ( p < 0.0001) than the performance goal (20%). There was a reduction of -2.93 (5.24) days of acute medication use, headache impact measured by HIT-6, -3.1 (6.4) ( p < 0.0001), and total headache days of any intensity -3.16 days (5.21) compared to the performance goal (-0.63 days) ( p < 0.0001). The most common adverse events were lightheadedness (3.7%), tingling (3.2%), and tinnitus (3.2%). There were no serious adverse events. Conclusions This open label study suggests that sTMS may be an effective, well-tolerated treatment option for migraine prevention. Trial registration number NCT02357381.

The objective of this study was to evaluate the effects of 8mg dexamethasone injection into the pterygomandibular space on the postoperative sequelae of lower third molar surgery. A prospective, randomized, controlled, split-mouth study was designed involving 62 lower third molar extractions (31 patients). Prior to surgery, the study group received 2ml of 4mg/ml (8mg) dexamethasone injection through the pterygomandibular space following local anaesthesia; the control group received 2ml normal saline injection. Facial swelling, mouth opening, pain on a visual analogue scale (VAS), and the number of analgesics consumed were assessed. Descriptive statistics and the independent-samples t-test were used to compare the two groups at P<0.05. There was a significant reduction in swelling on day 2 postoperative in the dexamethasone group. Mouth opening was also significantly greater on day 2 in the dexamethasone group. The VAS pain score was significantly lower on the day of the operation and first postoperative day in the dexamethasone group, but did not differ significantly between the groups on the other postoperative days. The injection of 8mg dexamethasone into the pterygomandibular space was effective in reducing postoperative swelling, limited mouth opening, and pain following impacted lower third molar extraction.

A total of 24 Sprague-Dawley rats were randomly divided into Tarantula cubensis extract (TCE1, n=8) 1/10 diluted, TCE (TCE2, n=8), and (3) vehicle-control (0.2 ml of 96 % ethanol, n=8) groups. Experimental full-thickness 1 x 1cm wounds were created on dorsum skin. TCE or vehicle were given systemically by subcutaneous injections on postoperative days 1 and 4. Wound planimetry and procurement of biopsies was performed on days 4, 8, 12 and 16. The mean non-epithelialised wound area in the vehicle-control group was significantly larger than in the TCE1 group on days 4, 8, 12 and 16, and in the TCE2 group on days 8, 12 and 16 (p<0.05). The mean percentage of wound contraction was significantly higher in the TCE1 and TCE2 groups than in the vehicle control group on days 8, 12 and 16 (p<0.05). Histopathologically, wound healing was characterised by a significant decrease in the neutrophil counts and a significant increase in neovascularisation; neither were effected by TCE. Our results suggest that alcohol extract of Tarantula cubensis accelerates epithelialisation and, thus, has beneficial effects on open wound healing in rats.

The objective of this study was to compare the total hospital cost of laparoscopic (lap) and open colon surgery at a publicly funded academic institution. Patients undergoing elective laparoscopic or open colon surgery for all indications at the University Health Network, Toronto, Canada, from April 2004 to March 2009 were included. Patient demographic, operative, and outcome data were reviewed retrospectively. Hospital costs were determined from the Ontario Case Costing Initiative, adjusted for inflation, and compared using the Mann-Whitney U test. Linear regression was used to analyze the relationship between length of stay and total hospital cost. There were 391 elective colon resections (223 lap/168 open, 15.4 % conversion). There was no difference in median age, gender, or Charlson score. Body mass index was slightly higher for laparoscopic surgery (27.5/25.9 lap/open; p = 0.008), while the American Society of Anesthesiologists score was slightly higher for open surgery. Median operative time was greater for laparoscopic surgery (224/196 min, lap/open; p = 0.001). There was no difference in complication rates (21.6/22.5 % lap/open; p = 0.900), reoperations (5.8/6.5 % lap/open; p = 0.833) or 30-day readmissions (7.6/12.5 % lap/open; p = 0.122). Number of emergency room visits was greater with open surgery (12.6/20.8 % lap/open; p = 0.037). Operative cost was higher for laparoscopic surgery ($4,171.37/3,489.29 lap/open; p = 0.001), while total hospital cost was significantly reduced ($9,600.22/12,721.41 lap/open; p = 0.001). Median length of stay was shorter for laparoscopic surgery (5/7 days lap/open; p = 0.000), and this correlated directly with hospital cost. Laparoscopic colon surgery is associated with increased operative costs but significantly lower total hospital costs. The cost savings is related, in part, to reduced length of stay with laparoscopic surgery.

Routine laparoscopic repair of primary unilateral inguinal hernias--a viable alternative in the day surgery unit?

PubMed

Duff, M; Mofidi, R; Nixon, S J

2007-08-01

In September 2004 the NICE institute revised its guidelines on the management of primary inguinal hernias to include laparoscopic repair of unilateral hernias. While published trials have confirmed the equal efficacy of the two approaches, it is not clear what impact a switch to laparoscopic repairs would have on resources and patient throughput in a Day Surgery Unit. All elective hernia repairs performed in a one-year period were considered. Data were obtained from operation notes, discharge summaries and out-patient records. Operating times are routinely documented in theatre. Of the 351 operations studied, 150 were performed laparoscopically predominantly by an extraperitoneal (TEP)approach. Six required conversion to an open procedure. There was no significant difference in operating times, total theatre time or recovery room times between the two groups (51 min, 75 min and 34 min for the laparoscopic group and 53 min, 74 min and 31 min for the open repair group). Among the laparoscopic repair group there were 48 bilateral hernias and 20 recurrent hernias while 190 of the 201 open repairs were for primary unilateral hernias. Rates of overnight stay and immediate complications were similar between the groups though haematoma was more common following open repair (7 vs 2). There is no difference in theatre times, immediate complication rates or rates of overnight stay between open and laparoscopic repair of inguinal hernia. Routine laparoscopic repair of primary unilateral inguinal hernia is a viable alternative within the Day Surgery Unit.

To evaluate the clinical outcome of a novel open-tray impression technique for fabrication of a provisional prosthesis supported by immediately loaded implants in a completely edentulous arch. An open-tray impression technique was evaluated in this retrospective study that included patients treated between March 2006 and October 2009. Preoperatively, a diagnostic prosthesis was delivered, and a novel open tray was fabricated based on this prosthesis. After implant placement, the impression and interocclusal record were taken simultaneously using the novel open tray. Laboratory-fabricated, screw-retained, all-acrylic resin provisional restorations were delivered on the same day of surgery. The prosthesis was assessed from the day of surgery until replacement with a definitive prosthesis. The study included 21 patients (mean age, 64.5 years) and a total of 125 implants. Of these, 104 implants were immediately loaded. In all patients, well-fitting provisional restorations supported by a minimum of four implants were delivered. Fracture of the first molar cusp was observed in one case after 30 days. However, there was no extensive fracture in the framework or functional disorder of the prosthesis. No implant failed during the follow-up after implant surgery. This protocol enabled fabrication of a well-fitting acrylic resin provisional prosthesis supported by immediately loaded implants because the impression was taken while in centric occlusion and an occlusion identical to the diagnostic prosthesis could be reconstructed.

We sought to describe the safety profile of open-label, adjunctive deferasirox iron chelation therapy in eight patients with biopsy-proven mucormycosis. Deferasirox was administered for an average of 14 days (range, 7 to 21) at 5 to 20 mg/kg of body weight/day. The only adverse effects attributable to deferasirox were rashes in two patients. Deferasirox treatment was not associated with changes in renal or liver function, complete blood count, or transplant immunosuppressive levels. Thus, deferasirox appears safe as an adjunctive therapy for mucormycosis. PMID:19433555

Individuals high in the personality trait Openness to Experience appear to engage spontaneously (during wake) in processes of elaborative encoding similar to those Llewellyn identifies in both dreaming and the ancient art of memory (AAOM). Links between Openness and dreaming support the hypothesis that dreaming is part of a larger process of cognitive exploration that facilitates adaptation to new experiences.

Time-sensitive alerts are among the many types of clinical notifications delivered to physicians' secure InBaskets within commercial electronic health records (EHRs). A delayed alert review can impact patient safety and compromise care. To characterize factors associated with opening of non-interruptive time-sensitive alerts delivered into primary care provider (PCP) InBaskets. We analyzed data for 799 automated alerts. Alerts highlighted actionable medication concerns for older patients post-hospital discharge (2010-2011). These were study-generated alerts sent 3 days post-discharge to InBaskets for 75 PCPs across a multisite healthcare system, and represent a subset of all urgent InBasket notifications. Using EHR access and audit logs to track alert opening, we performed bivariate and multivariate analyses calculating associations between patient characteristics, provider characteristics, contextual factors at the time of alert delivery (number of InBasket notifications, weekday), and alert opening within 24 h. At the time of alert delivery, the PCPs had a median of 69 InBasket notifications and had received a median of 379.8 notifications (IQR 295.0, 492.0) over the prior 7 days. Of the 799 alerts, 47.1% were opened within 24 h. Patients with longer hospital stays (>4 days) were marginally more likely to have alerts opened (OR 1.48 [95% CI 1.00-2.19]). Alerts delivered to PCPs whose InBaskets had a higher number of notifications at the time of alert delivery were significantly less likely to be opened within 24 h (top quartile >157 notifications: OR 0.34 [95% CI 0.18-0.61]; reference bottom quartile ≤42). Alerts delivered on Saturdays were also less likely to be opened within 24 h (OR 0.18 [CI 0.08-0.39]). The number of total InBasket notifications and weekend delivery may impact the opening of time-sensitive EHR alerts. Further study is needed to support safe and effective approaches to care team management of InBasket notifications.

A study of the effect of a single neurotoxic dose of 3,4-methylenedioxymethamphetamine (MDMA; "ecstasy") on the subsequent long-term behaviour of rats in the plus maze and open field.

Decreased 5-HT function has been shown to induce behaviour consistent with an "anxiolytic" effect. Administration of a single dose of 3,4-methylenedioxymethamphetamine (MDMA; "ecstasy" 12.5 mg/kg IP) to rats results in prolonged damage to central serotonergic nerve terminals. Thus we wished to assess whether an MDMA-induced lesion may have longer-term behavioural consequences. The study was designed to examine the behaviour of MDMA-pretreated and control animals in the elevated plus-maze and open field at a number of time-points, up to 80 days, after the administration of a single neurotoxic dose of MDMA (12.5 mg/kg IP). MDMA-pretreated Dark Agouti rats demonstrated a statistically significant reduction in anxiety-related behaviour, compared to saline-pretreated control rats, in both the elevated plus-maze and open field when the rats were tested on day 73 (open field) and day 80 (plus maze) after MDMA administration. The behavioural consequences of a single neurotoxic dose of MDMA can be demonstrated over 2 months after administration of the compound, thereby indicating that long-term adaptive changes occur within the brain following the neurodegeneration of 5-HT neurones produced by this recreationally used drug.

Role of ranitidine in negative symptoms of schizophrenia--an open label study.

PubMed

Mehta, Varun S; Ram, Daya

2014-12-01

In this open label study, 75 patients with a diagnosis of schizophrenia were randomized to three groups of 25 each, receiving 150mg/day ranitidine, 300mg/day ranitidine and receiving only olanzapine. They were rated on PANSS at baseline, 4 and 8 weeks. There was a significant reduction in the scores of negative scale in patients receiving 300mg/day ranitidine in comparison to patients not receiving ranitidine at the end of 4 weeks but was not seen again when assessed at the end of 8 weeks. Though effective in reducing the negative symptoms, the effect was not sustained due to the tolerance to the actions of ranitidine. Copyright © 2014 Elsevier B.V. All rights reserved.

We present two cases in which a 10-month-old male infant and another 15-month-old female child presented with symptoms of sleeping with their eyes wide open (lagophthalmos) with features of gastroenteritis (GE) and dehydration. The first child had been seen and discharged the previous day from the paediatric emergency department (ED) with a diagnosis of GE. He presented the following day with sleeping discomfort with his eyes wide open and ongoing symptoms of GE. The second child presented to the ED with features of GE. She was found to be sleeping in the ED with her eyes wide open. Investigations of both children revealed hypernatraemic dehydration. Correction of the electrolyte imbalance in both cases over a period of 48 h led to the resolution of symptoms.

Transversus abdominis plane block (TAPb) is an analgesic adjunct used for abdominal surgical procedures. Liposomal bupivacaine (LB) demonstrates prolonged analgesic effects, up to 72 hours. We evaluated the analgesic efficacy of TAPb using LB for patients undergoing open abdominal wall reconstruction (AWR). Fifty patients undergoing AWR with TAPb using LB (TAP-group) were compared with a matched historical cohort undergoing AWR without TAPb (control group). Outcome measures included postoperative utilization of morphine equivalents, numerical rating scale pain scores, time to oral narcotics, and length of stay (LOS). Cohorts were matched demographically. No complications were associated with TAPb or LB. TAP-group evidenced significantly reduced narcotic requirements on operative day (9.5 mg vs 16.5 mg, P = .004), postoperative day (POD) 1 (26.7 mg vs 39.5 mg, P = .01) and POD2 (29.6 mg vs 40.7 mg, P = .047) and pain scores on operative day (5.1 vs 7.0, P <.001), POD1 (4.2 vs 5.5, P = .002), and POD2 (3.9 vs 4.8, P = .04). In addition, TAP-group demonstrated significantly shorter time to oral narcotics (2.7 days vs 4.0 days, P <.001) and median LOS (5.2 days vs 6.8 days, P = .004). TAPb with LB demonstrated significant reductions in narcotic consumption and improved pain control. TAPb allowed for earlier discontinuation of intravenous narcotics and shorter LOS. Intraoperative TAPb with LB appears to be an effective adjunct for perioperative analgesia in patients undergoing open AWR. Copyright © 2016 Elsevier Inc. All rights reserved.

We examined: (a) the response to bidirectional selection for open-field (OF) thigmotaxis in mice for 23 generations and (b) the effects of repeated exposure (during 5 days) on different OF behaviors in the selectively bred high OF thigmotaxis (HOFT) and low OF thigmotaxis (LOFT) mice. A total of 2049 mice were used in the study. Prior to the testing in the selection experiment, the mice were exposed to the OF apparatus for approximately 2 min on each of 4 consecutive days. Thus, the selection was based on the scores registered on the 5th day after the four habituation periods. The HOFT mice were more thigmotactic than the LOFT mice in almost each generation. The HOFT mice also tended to rear less than the LOFT mice, which was explained by the inverse relationship between emotionality and exploratory tendencies. The lines did not generally differ in ambulation. Sex differences were found in thigmotaxis, ambulation, and rearing. In the repeated exposure experiment, the development of nine different OF behaviors across the 5 days of testing was addressed. Both lines ambulated, explored, and reared most on the 1st, 4th, and 5th days. Grooming and radial latency decreased and thigmotaxis increased linearly across the testing days. Line differences were found in ambulation, exploration, grooming, and rearing, while sex differences were manifested in ambulation and exploration. The line difference in thigmotaxis was evident only on the 5th day. Temporal changes were partially at variance with the general assumptions. OF thigmotaxis was found to be a powerful characteristic for producing two diverging lines of mice.

Open Repair Versus Thoracic Endovascular Aortic Repair in Multiple-Injured Patients: Observations From a Level-1 Trauma Center

Background: Blunt trauma of the thoracic aorta is a rare but potentially life-threatening entity. Intimal tears are a domain of non-operative management, whereas all other types of lesions should be repaired urgently. There is now a clear trend favoring minimally invasive stent grafting over open surgical repair. Objectives: The aim of the present study was to retrospectively evaluate the mortality and morbidity with either treatment option. Therefore, a retrospective observational study was performed to compare two different treatment methods at two different time periods at one trauma center. Patients and Methods: Between 1977 and 2012, all severely injured patients referred to our level 1 trauma center were screened for blunt aortic injuries. We compared baseline characteristics, 30-day and overall mortality, morbidity, duration of intensive care treatment, procedure time, and transfusion of packed red blood between patients who underwent open surgical or stent repair. Results: During the observation period, 45 blunt aortic injuries were recorded. The average Injury Severity Score (ISS) was 41.8 (range 29 - 68). Twenty-five patients underwent Open Repair (OR), and another 20 patients were scheduled to emergency stent grafting. The 30-day mortality in the surgical and stent groups were 5/25 (20%) and 2/20 (10%), respectively. The average time for open surgery was 151 minutes; the mean time for stent grafting was 67 minutes (P = 0.001). Postoperative stay on the intensive care unit was between one and 59 days (median 10) in group one and between four and 50 days in group two (median 26)(P = 0.03). Patients undergoing OR required transfusion of 6.0 units of packed red cells in median; patients undergoing stent grafting required a median of 2.0 units of packed red cells (P < 0.001). In the stent grafting group, 30-day mortality was 10% (2/20). Conclusions: Due to more sophisticated diagnostic tools and surgical approaches, mortality and morbidity of blunt aortic injuries were significantly reduced over the years compared to thoracic endovascular aortic repair and OR over two different time periods.

To determine if open-access scheduling would reduce the cancellation rate for new patient evaluations in a chronic pain clinic by at least 50%. Retrospective, observational study using electronic health records. Chronic pain clinic of an academic anesthesia department. All patients scheduled for evaluation or follow-up appointments in the chronic pain clinic between April 1, 2014, and December 31, 2015. Open-access scheduling was instituted in April 2015 with appointments offered on a date of the patient's choosing ≥1 business day after calling, with no limit on the daily number of new patients. Mean cancellation rates for new patients were compared between the 12-month baseline period prior to and for 7months after the change, following an intervening 2-month washout period. The method of batch means (by month) and the 2-sided Student t-test were used; P<0.01 required for significance. The new patient mean cancellation rate decreased from a baseline of 35.7% by 4.2% (95% confidence interval [CI] 1.4% to 6.9%; P=0.005); however, this failed to reach the 50% reduction target of 17.8%. Appointment lag time decreased by 4.7days (95% CI 2.3 to 7.0days, P<0.001) from 14.1days to 9.4days in the new patient group. More new patients were seen within 1week compared to baseline (50.6% versus 19.1%; P<0.0001). The mean number of new patient visits per month increased from 158.5 to 225.0 (P=0.0004). The cancellation rate and appointment lag times did not decrease for established patient visits, as expected because open-access scheduling was not implemented for this group. Access to care for new chronic pain patients improved with modified open-access scheduling. However, their mean cancellation rate only decreased from 35.7% to 31.5%, making this a marginally effective strategy to reduce cancellations. Copyright © 2017 Elsevier Inc. All rights reserved.

Management of perforated peptic ulcer in a district general hospital.

2011-11-01

Laparoscopic surgery has become increasingly popular for elective surgery but it has gained slow transference to emergency surgery. The management of perforated peptic ulcers (PPU) laparoscopically is an accepted strategy yet it still remains infrequently used. The purpose of this study was to analyse the utility and outcomes of laparoscopy versus open repair for PPU in a district general hospital. In addition, we evaluated whether the subspecialty of the on-call consultant affected the method of repair performed and the training opportunities for trainee surgeons. Between 2003 and 2009, 53 patients underwent laparoscopic repair, 89 patients underwent open repair and a further 20 patients had laparoscopic repair that was converted to open repair for PPU. The results from a prospectively compiled database were analysed with primary outcome measures including operative time, length of hospital stay and mortality. The median operating time in the laparoscopic group was 60.0 minutes compared with 50.5 minutes in the open group. Hospital stay in surviving patients was significantly shorter in patients treated completely laparoscopically (5 days) when compared with the open group (6 days) ( p <0.01). There were six deaths in the laparoscopic group (11%) compared with 13 in the open group (15%) and one in the converted group (5%). Trainees performed 53% (47/89) of open repairs and 13% (7/54) of laparoscopic repairs. Both laparoscopic and open repair are equally safe in the management of PPU. Our findings support the view that this procedure can be successfully used as a training operation.

2011-01-01

Duodenal ulcer perforation still occurs frequently in the 21st century inspite of the wide availability of proton pump inhibitors. During 2005-2008, 34 patients underwent treatment of duodenal ulcer perforation at the University Hospital Lewisham, London. Laparoscopic or open repair of the perforation was used. In this study, we analysed the outcome of treatment in terms of complications, mortality and hospital stay with relevant to laparoscopy and open approach. Ten patients underwent laparoscopic closure and the remaining 24 patients underwent laparotomy. The mean hospital stay for the laparoscopic group was 6.6 days and for open repair group was 12.8 days. There were two wound infection related to open approach and four patients died during the post operative period however the cause of death was not related to the procedure. Laparoscopy has the advantage of avoiding a big incision and will enable the patient to get discharged home early. However, the only limiting factor is availability of expertise and competency of the surgeon.

The aim of this study was to compare periorbital edema and ecchymosis seen after closed (endonasal) and open (external) septorhinoplasty (SRP). In total, 50 patients undergoing hump extraction and osteotomies were allocated to 2 groups. Group 1 consisted of 25 patients who underwent closed SRP. Group 2 consisted of 25 patients who underwent open SRP. Operation time, amount of intraoperative bleeding, and complications were recorded. Scoring of eyelid edema and periorbital ecchymosis was evaluated on the first, third, and seventh postoperative days using a scale of 0 to 4 by the first author. There was no statistically significant difference between the groups in terms of age, sex, or operation time. No significant difference was observed clinically or statistically in the scores of periorbital edema or ecchymosis between groups 1 and 2 on the first, third, and seventh postoperative days (P > 0.05). The authors observed no clinically or statistically significant difference in comparing periorbital edema and ecchymosis seen after closed and open SRP.

Negative pressure wound therapy combined with acoustic pressure wound therapy for infected post surgery wounds: a case series.

2008-09-01

Acute infection of surgical incision sites often requires specialized wound care in preparation for surgical closure. Optimal therapy for preparing such wounds for a secondary closure procedure remains uncertain. The authors report wound outcomes after administering acoustic pressure wound therapy in conjunction with negative pressure wound therapy with reticulated open-cell foam dressing changes to assist with bacteria removal from open, infected surgical-incision sites in preparation for secondary surgical closure in three patients. Before incorporating acoustic pressure wound therapy at the authors' facility, the average negative pressure wound therapy with reticulated open-cell foam dressing course prior to secondary surgical closure was 30 days; with its addition, two of three patients underwent successful surgical closure with no postoperative complications after 21 and 14 days, respectively; one patient succumbed to nonwound-related complications before wound closure. Larger, prospective studies are needed to evaluate combining negative pressure wound therapy with reticulated open-cell foam dressing and acoustic pressure wound therapy for infected, acute post surgery wounds.

Minimally invasive instrumentation without fusion during posterior thoracic corpectomies: a comparison of percutaneously instrumented nonfused segments with open instrumented fused segments.

PubMed

Lau, Darryl; Chou, Dean

2017-07-01

OBJECTIVE During the mini-open posterior corpectomy, percutaneous instrumentation without fusion is performed above and below the corpectomy level. In this study, the authors' goal was to compare the perioperative and long-term implant failure rates of patients who underwent nonfused percutaneous instrumentation with those of patients who underwent traditional open instrumented fusion. METHODS Adult patients who underwent posterior thoracic corpectomies with cage reconstruction between 2009 and 2014 were identified. Patients who underwent mini-open corpectomy had percutaneous instrumentation without fusion, and patients who underwent open corpectomy had instrumented fusion above and below the corpectomy site. The authors compared perioperative outcomes and rates of implant failure requiring reoperation between the open (fused) and mini-open (unfused) groups. RESULTS A total of 75 patients were identified, and 53 patients (32 open and 21 mini-open) were available for followup. The mean patient age was 52.8 years, and 56.6% of patients were male. There were no significant differences in baseline variables between the 2 groups. The overall perioperative complication rate was 15.1%, and there was no significant difference between the open and mini-open groups (18.8% vs 9.5%; p = 0.359). The mean hospital stay was 10.5 days. The open group required a significantly longer stay than the mini-open group (12.8 vs 7.1 days; p < 0.001). Overall implant failure rates requiring reoperation were 1.9% at 6 months, 9.1% at 1 year, and 14.7% at 2 years. There were no significant differences in reoperation rates between the open and mini-open groups at 6 months (3.1% vs 0.0%, p = 0.413), 1 year (10.7% vs 6.2%, p = 0.620), and 2 years (18.2% vs 8.3%, p = 0.438). The overall mean follow-up was 29.2 months. CONCLUSIONS These findings suggest that percutaneous instrumentation without fusion in mini-open transpedicular corpectomies offers similar implant failure and reoperation rates as open instrumented fusion as far out as 2 years of follow-up.

In this study, we aimed to evaluate, the efficacy of surgical methods and the factors affecting the residual stone rate by scrutinizing retrospectively the patients who had undergone renal stone surgery. Records of 109 cases of kidney stones who had been surgically treated between January 2010, and July 2013 were reviewed. Patients were divided into three groups in terms of surgical treatment; open stone surgery, percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS). Patients' history, physical examination, biochemical and radiological images and operative and postoperative data were recorded. The patients had undergone PNL (n=74; 67.9%), RIRS (n=22;20.2%), and open renal surgery (n=13; 11.9%). The mean and median ages of the patients were 46±9, 41 (21-75) and, 42 (23-67) years, respectively. The mean stone burden was 2.6±0.7 cm(2) in the PNL, 1.4±0.1 cm(2) in the RIRS, and 3.1±0.9 cm(2) in the open surgery groups. The mean operative times were 126±24 min in the PNL group, 72±12 min in the RIRS group and 82±22 min in the open surgery group. The duration of hospitalisation was 3.1±0.2 days, 1.2±0.3 days and 3.4±1.1 days respectively. While the RIRS group did not need blood transfusion, in the PNL group blood transfusions were given in the PNL (n=18), and open surgery (n=2) groups. Residual stones were detected in the PNL (n=22), open surgery (n=2), and RIRS (n=5) groups. PNL and RIRS have been seen as safe and effective methods in our self application too. However, it should not be forgotten that as a basical method, open surgery may be needed in cases of necessity.

San Pablo Bay is an estuary, within northern San Francisco Bay, containing elevated sediment mercury (Hg) levels because of historic loading of hydraulic mining debris during the California gold-rush of the late 1800s. A preliminary investigation of benthic microbial Hg cycling was conducted in surface sediment (0-4 cm) collected from one salt-marsh and three open-water sites. A deeper profile (0-26 cm) was evaluated at one of the open-water locations. Radiolabeled model Hg-compounds were used to measure rates of both methylmercury (MeHg) production and degradation by bacteria. While all sites and depths had similar total-Hg concentrations (0.3-0.6 ppm), and geochemical signatures of mining debris (as eNd, range: -3.08 to -4.37), in-situ MeHg was highest in the marsh (5.4??3.5 ppb) and ??? 0.7 ppb in all open-water sites. Microbial MeHg production (potential rate) in 0-4 surface sediments was also highest in the marsh (3.1 ng g-1 wet sediment day-1) and below detection (<0.06 ng g-1 wet sediment day-1) in open-water locations. The marsh exhibited a methylation/demethylation (M/D) ratio more than 25x that of all open-water locations. Only below the surface 0-4-cm horizon was significant MeHg production potential evident in the open-water sediment profile (0.2-1.1 ng g-1 wet sediment day-1). In-situ Hg methylation rates, calculated from radiotracer rate constants, and in-situ inorganic Hg(II) concentrations compared well with potential rates. However, similarly calculated in-situ rates of MeHg degradation were much lower than potential rates. These preliminary data indicate that wetlands surrounding San Pablo Bay represent important zones of MeHg production, more so than similarly Hg-contaminated adjacent open-water areas. This has significant implications for this and other Hg-impacted systems, where wetland expansion is currently planned.

Acute limb ischemia (ALI) of the lower extremity is a potentially devastating condition that requires urgent and definitive management. This challenging scenario is often treated with endovascular, open surgical, or hybrid revascularization (HyR) in an urgent basis, but the comparative effects of such therapies remain poorly defined. The purpose of this study was to compare the outcomes of endovascular, open surgical, and HyR for ALI in the contemporary era. A large statewide cardiovascular consortium of 45 hospitals was queried for patients between January 2012 and June 2015 who underwent an endovascular, open surgical, or HyR for ALI deemed at high risk of limb loss if not treated within 24 hr (Rutherford class IIA or IIB). A propensity score weighted analysis was performed controlling for demographics, medical history, and procedure type for patients. The primary outcomes were 30-day morbidity and mortality. A total of 1,480 patients underwent endovascular revascularization (ER; n = 818), open surgical revascularization (OSR; n = 195), or hybrid revascularization (HyR; n = 467) for ALI. The mean age was similar across revascularization technique with an increased predominance of male gender in open surgery cohort. Comorbidities for all groups were consistent with peripheral arterial disease. The most common endovascular procedures were angioplasty (93%) and thrombolysis (49.8%), whereas the most common surgical revascularization was femoral to popliteal bypass (32.8%), femoral to tibial bypass (28.2%), and thrombectomy (19.0%); ER as compared with OSR and HyR procedures was associated with less transfusion (OSR versus ER, odds ratio [OR] 2.7; HyR versus ER, OR 2.8; P < 0.001) and major amputation (OSR versus ER, OR 3.4; HyR versus ER, OR 4.0; P < 0.001) within 30 days of intervention. There was no difference in 30-day freedom from reintervention, myocardial infarction (MI), or mortality. Among patients requiring urgent revascularization for Rutherford grade IIA and IIB ischemia, ER has lower 30-day morbidity but similar mortality and rates of reintervention. Although long-term patency rates were not compared, ER may offer superior short-term outcomes compared with open surgery and hybrid revascularization. Copyright © 2018 Elsevier Inc.

Response of respiration and nutrient availability to drying and rewetting in soil from a semi-arid woodland depends on vegetation patch and a recent wildfire

Sun, Q.; Meyer, W. S.; Koerber, G. R.; Marschner, P.

2015-08-01

Semi-arid woodlands, which are characterised by patchy vegetation interspersed with bare, open areas, are frequently exposed to wildfire. During summer, long dry periods are occasionally interrupted by rainfall events. It is well known that rewetting of dry soil induces a flush of respiration. However, the magnitude of the flush may differ between vegetation patches and open areas because of different organic matter content, which could be further modulated by wildfire. Soils were collected from under trees, under shrubs or in open areas in unburnt and burnt sandy mallee woodland, where part of the woodland experienced a wildfire which destroyed or damaged most of the aboveground plant parts 4 months before sampling. In an incubation experiment, the soils were exposed to two moisture treatments: constantly moist (CM) and drying and rewetting (DRW). In CM, soils were incubated at 80 % of maximum water holding capacity (WHC) for 19 days; in DRW, soils were dried for 4 days, kept dry for another 5 days, then rewetted to 80 % WHC and maintained at this water content until day 19. Soil respiration decreased during drying and was very low in the dry period; rewetting induced a respiration flush. Compared to soil under shrubs and in open areas, cumulative respiration per gram of soil in CM and DRW was greater under trees, but lower when expressed per gram of total organic carbon (TOC). Organic matter content, available P, and microbial biomass C, but not available N, were greater under trees than in open areas. Wild fire decreased the flush of respiration per gram of TOC in the open areas and under shrubs, and reduced TOC and microbial biomass C (MBC) concentrations only under trees, but had little effect on available N and P concentrations. We conclude that the impact of wildfire and DRW events on nutrient cycling differs among vegetation patches of a native semi-arid woodland which is related to organic matter amount and availability.

Timing of spring wild turkey hunting in relation to nest incubation

State wildlife agencies are often requested to open spring wild turkey (Meleagris gallopavo; hereafter, turkey) hunting seasons earlier to increase hunter satisfaction by hunters hearing more gobbling male turkeys. Timing of spring turkey hunting season in several states, including Pennsylvania, has been established to open, on average, near median date of incubation initiation of turkey nests. This is believed to reduce illegal and undesired hen harvest and possibly nest abandonment, while maintaining hunter satisfaction of hearing male turkeys when most hens are incubating eggs. However, Pennsylvania’s spring season structure was established in 1968. Given earlier spring phenology, and potentially more variation in spring weather due to climate change, there is concern that timing of nest incubation for turkeys in Pennsylvania could be changing. Therefore, our objective was to determine if nest incubation and opening of spring turkey hunting in Pennsylvania have continued to coincide. We attached satellite transmitters to 254 female turkeys during 2010–2014 and estimated median incubation initiation date to be 2 May, which was 2 days earlier than median date during a statewide study during 1953–1963 and 9 days earlier than during a smaller scale study in south–central Pennsylvania during 2000–2001. However, incubation initiation varied greatly among years and individual hens during all 3 studies. During 4 of 5 years of our study, Pennsylvania’s spring season opened 3 to 8 days prior to median date of incubation initiation. Over the 5 years, estimated initiation of incubation for first nesting attempts, measured from earliest date of incubation initiation to latest, was >2 months and maximum proportion of hens beginning incubation at any one time differed by several days to >1 week. Consequently, in years of late incubation, a constant season opening date set near the long-term median date of incubation initiation exposes few additional hens to risk and hunter satisfaction is likely maintained at greater levels than would be seen with a more conservative approach of opening the season later. Long-term and large scale studies using GPS transmitters that provide precise determination of incubation initiation will be useful to study environmental influences on initiation of incubation.

The aim of this study was to evaluate the benefit of oral ubiquinol-10 supplementation in CFS patients using an open-label study and a randomized, double-blinded, placebo-controlled (RCT) study. Twenty patients with CFS were randomly enrolled in an 8-week open-label oral ubiquinol-10 (150 mg ubiquinol-10/day) study. The patients and the attending physicians were not blinded to the supplementation. Forty-three patients with CFS were randomly assigned to receive either ubiquinol-10 (150 mg/day) or placebo every day for 12 weeks. The patients and the attending physicians were blinded to the supplementation, and a total of 31 patients (N = 17 in the ubiquinol group and 14 in the placebo group) completed the study. The beneficial effects of ubiquinol-10 were observed in the open-label study we conducted prior to the RCT. The RCT results suggest that supplementation with ubiquinol-10 for 12 weeks is effective for improving several CFS symptoms. © 2016 BioFactors, 42(4):431-440, 2016. © 2016 International Union of Biochemistry and Molecular Biology.

Factors affecting reproductive performance of dairy cows.

PubMed

Coleman, D A; Thayne, W V; Dailey, R A

1985-07-01

We conducted two studies to determine how herd management practices and traits of individual cows affect performance of the herd and of the cow within a herd. Management practices, reproductive performance of the herd, and relationships between management and reproductive performance were characterized on 83 dairy farms with 7596 cows. Data included 21 management variables (e.g., facilities, herd health program, estrous detection program) and 8 performance variables obtained from Dairy Herd Improvement or unofficial records (e.g., size of herd, production, days open). Although varying among herds, annual average herd incidences of reproductive disorders and reproductive performance were similar to those reported. Managerial practices influenced incidences of retained placenta and uterine infection, days open of cows not bred and of all cows, services per conception, and percentages of herd open more than 100 days and culled for low production. Veterinarian was the most consistent variable influencing herd reproductive performance. Data also were collected from production and lifetime records of 2532 cows in 19 herds. Reproductive performance was affected by season of calving, production, maturity, and reproductive disorders. Several cows with extremely poor reproductive records were maintained.

In 2009, the NHS evidence adoption center and National Institute for Health and Care Excellence (NICE) published a review of the use of endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAAs). They recommended the development of a risk-assessment tool to help identify AAA patients with greater or lesser risk of operative mortality and to contribute to mortality prediction.A low anaerobic threshold (AT), which is a reliable, objective measure of pre-operative cardiorespiratory fitness, as determined by pre-operative cardiopulmonary exercise testing (CPET) is associated with poor surgical outcomes for major abdominal surgery. We aimed to assess the impact of a CPET-based risk-stratification strategy upon perioperative mortality, length of stay and non-operative costs for elective (open and endovascular) infra-renal AAA patients. A retrospective cohort study was undertaken. Pre-operative CPET-based selection for elective surgical intervention was introduced in 2007. An anonymized cohort of 230 consecutive infra-renal AAA patients (2007 to 2011) was studied. A historical control group of 128 consecutive infra-renal AAA patients (2003 to 2007) was identified for comparison.Comparative analysis of demographic and outcome data for CPET-pass (AT ≥ 11 ml/kg/min), CPET-fail (AT < 11 ml/kg/min) and CPET-submaximal (no AT generated) subgroups with control subjects was performed. Primary outcomes included 30-day mortality, survival and length of stay (LOS); secondary outcomes were non-operative inpatient costs. Of 230 subjects, 188 underwent CPET: CPET-pass n = 131, CPET-fail n = 35 and CPET-submaximal n = 22. When compared to the controls, CPET-pass patients exhibited reduced median total LOS (10 vs 13 days for open surgery, n = 74, P < 0.01 and 4 vs 6 days for EVAR, n = 29, P < 0.05), intensive therapy unit requirement (3 vs 4 days for open repair only, P < 0.001), non-operative costs (£5,387 vs £9,634 for open repair, P < 0.001) and perioperative mortality (2.7% vs 12.6% (odds ratio: 0.19) for open repair only, P < 0.05). CPET-stratified (open/endovascular) patients exhibited a mid-term survival benefit (P < 0.05). In this retrospective cohort study, a pre-operative AT > 11 ml/kg/min was associated with reduced perioperative mortality (open cases only), LOS, survival and inpatient costs (open and endovascular repair) for elective infra-renal AAA surgery.

Medical care has been evolving with the increased influence of a value-based health care system. As a result, more emphasis is being placed on ensuring cost-effectiveness and utility in the services provided to patients. This study looks at this development in respect to minimally invasive spine surgery (MISS) costs. A literature review using PubMed, the Cost-Effectiveness Analysis (CEA) Registry, and the National Health Service Economic Evaluation Database (NHS EED) was performed. Papers were included in the study if they reported costs associated with minimally invasive spine surgery (MISS). If there was no mention of cost, CEA, cost-utility analysis (CUA), quality-adjusted life year (QALY), quality, or outcomes mentioned, then the article was excluded. Fourteen studies reporting costs associated with MISS in 12,425 patients (3675 undergoing minimally invasive procedures and 8750 undergoing open procedures) were identified through PubMed, the CEA Registry, and NHS EED. The percent cost difference between minimally invasive and open approaches ranged from 2.54% to 33.68%-all indicating cost saving with a minimally invasive surgical approach. Average length of stay (LOS) for minimally invasive surgery ranged from 0.93 days to 5.1 days compared with 1.53 days to 12 days for an open approach. All studies reporting EBL reported lower volume loss in an MISS approach (range 10-392.5 ml) than in an open approach (range 55-535.5 ml). There are currently an insufficient number of studies published reporting the costs of MISS. Of the studies published, none have followed a standardized method of reporting and analyzing cost data. Preliminary findings analyzing the 14 studies showed both cost saving and better outcomes in MISS compared with an open approach. However, more Level I CEA/CUA studies including cost/QALY evaluations with specifics of the techniques utilized need to be reported in a standardized manner to make more accurate conclusions on the cost effectiveness of minimally invasive spine surgery.

To present the management of open abdomen with colorectal fistula by application of intrarectal negative pressure system (NPS) in addition to abdominal NPS. Twenty-year old man had a history of injuries by a close-range gunshot to the abdomen eight days ago and he had been treated by bowel repairs, resections, jejunal anastomosis and Hartman's procedure. He was referred to our center after deterioration, evisceration with open abdomen and enteric fistula in septic shock. There were edematous, fibrinous bowels and large multiple fistulas from the edematous rectal stump. APACHE II, Mannheim Peritoneal Index and Björck scores were 18, 33 and 3, respectively (expected mortality 100%). After intensive care for 5 days, he was treated by abdominal and intrarectal NPS. NPS repeated for 5 times and the fistula was recovered on day 18 completely. Fascial closure was facilitated with a dynamic abdominal closure system (ABRA) and he was discharged on day 33 uneventfully. There was no herniation and any other problem after 12 months follow-up. Management of fistula in OA can be extremely challenging. Floating stoma, fistula VAC, nipple VAC, ring and silo VAC, fistula intubation systems are used for isolation of the enteric effluent from OA. Several biologic dressings such as acellular dermal matrix, pedicled flaps have been used to seal the fistula opening with various success. Resection of the involved enteric loop and a new anastomosis of the intestine is very hard and rarely possible. In all of these reports, usually patients are left to heal with a giant hernia. In contrast to this, there is no hernia in our case during one year follow up period. Combination of intra and extra luminal negative pressure systems and ABRA is a safe and successful method to manage open abdomen with colorectal fistula. Copyright © 2014 The Authors.

We previously documented that abatacept was effective and safe in patients with juvenile idiopathic arthritis (JIA) who had not previously achieved a satisfactory clinical response with disease-modifying antirheumatic drugs or tumor necrosis factor blockade. Here, we report results from the long-term extension (LTE) phase of that study. This report describes the long-term, open-label extension phase of a double-blind, randomized, controlled withdrawal trial in 190 patients with JIA ages 6-17 years. Children were treated with 10 mg/kg abatacept administered intravenously every 4 weeks, with or without methotrexate. Efficacy results were based on data derived from the 153 patients who entered the open-label LTE phase and reflect >or=21 months (589 days) of treatment. Safety results include all available open-label data as of May 7, 2008. Of the 190 enrolled patients, 153 entered the LTE. By day 589, 90%, 88%, 75%, 57%, and 39% of patients treated with abatacept during the double-blind and LTE phases achieved responses according to the American College of Rheumatology (ACR) Pediatric 30 (Pedi 30), Pedi 50, Pedi 70, Pedi 90, and Pedi 100 criteria for improvement, respectively. Similar response rates were observed by day 589 among patients previously treated with placebo. Among patients who had not achieved an ACR Pedi 30 response at the end of the open-label lead-in phase and who proceeded directly into the LTE, 73%, 64%, 46%, 18%, and 5% achieved ACR Pedi 30, Pedi 50, Pedi 70, Pedi 90, and Pedi 100 responses, respectively, by day 589 of the LTE. No cases of tuberculosis and no malignancies were reported during the LTE. Pneumonia developed in 3 patients, and multiple sclerosis developed in 1 patient. Abatacept provided clinically significant and durable efficacy in patients with JIA, including those who did not initially achieve an ACR Pedi 30 response during the initial 4-month open-label lead-in phase.

Studies of effects of closed microbial ecology. Report of 180-day test period

NASA Technical Reports Server (NTRS)

Kenyon, A. J.

1972-01-01

Experiments were performed to determine the influence closed microbial ecologies have on modification or simplification of natural intestinal flora of ferrets in a closed environmental system. On the basis of previous tests in which certain species (Salmonella and Bacteroides) were decreased at 90 days of enclosure, a second trial was constructed for 180-day tests. In this trial there was little difference in the 8 major classes of intestinal flora between animals in the Open and Closed environmental groups except for the level of Lactobacillus. It is of extreme importance to note that when both Open and Closed groups contracted hemorrhagic gastritis, the interrelationship of this agent with other intestinal flora produced a more profound effect on animals from the Closed Group, particularly with reference to Lactobacillus levels.

Introduction Historically symptomatic AAAs were found to have intermediate mortality compared to asymptomatic and ruptured AAAs but, with wider EVAR use, a more recent study suggested mortality of symptomatic aneurysms were similar to asymptomatic AAAs. These prior studies were limited by small numbers. The purpose of this study is to evaluate the mortality and morbidity associated with symptomatic AAA repair in a large contemporary population. Methods All patients undergoing infrarenal AAA repair were identified in the 2011–2013 ACS-NSQIP, Vascular Surgery targeted module. We excluded acute conversions to open repair and those for whom the surgical indication was embolization, dissection, thrombosis, or not documented. We compared 30-day mortality and major adverse events (MAE) for asymptomatic, symptomatic, and ruptured AAA repair, stratified by EVAR and open repair, with univariate analysis and multivariable logistic regression. Results 5502 infrarenal AAAs were identified, 4495 asymptomatic (830 open repair, 3665 [82%] EVAR), 455 symptomatic (143 open, 312 [69%] EVAR), and 552 ruptured aneurysms (263 open, 289 [52%] EVAR). Aneurysm diameter was similar between asymptomatic and symptomatic AAAs, when stratified by procedure type, but larger for ruptured aneurysms (EVAR symptomatic 5.8cm ±1.6 vs. ruptured 7.5cm ±2.0, P<.001; open repair symptomatic 6.4cm ±1.9 vs. ruptured 8.0cm ±1.9, P<.001). The proportion of females was similar in symptomatic and ruptured AAA (27% vs. 23%, P=.14, respectively), but lower in asymptomatic AAA (20%, P<.001). Symptomatic AAAs had intermediate 30-day mortality compared to asymptomatic and ruptured aneurysms after both EVAR (asymptomatic 1.4% vs. symptomatic 3.8%, P=.001; symptomatic vs. 22% ruptured, P<.001) and open repair (asymptomatic 4.3% vs. symptomatic 7.7% , P=.08; symptomatic vs. 57% ruptured, P<.001). After adjustment for age, gender, repair type, dialysis dependence, and history of severe COPD, patients undergoing repair of symptomatic AAAs were twice as likely to die within 30-days compared to those with asymptomatic aneurysms (OR 2.1, 95%CI 1.3–3.5). When stratified by repair type the effect size and direction of the odds ratios were similar (EVAR OR 2.4, CI 1.2–4.7; open repair OR 1.8, CI 0.86–3.9), although not significant for open repair. Patients with ruptured aneurysms had a sevenfold increased risk of 30-day mortality compared to symptomatic patients (OR 6.5, CI 4.1–10.6). Conclusion Patients with symptomatic AAAs had a two-fold increased risk of perioperative mortality, compared to asymptomatic aneurysms undergoing repair. Furthermore, patients with ruptured aneurysms have a seven-fold increased risk of mortality compared to symptomatic aneurysms. PMID:27146791

To evaluate the effect on ovarian follicular activity of the 91-day extended-regimen combined oral contraceptive (COC), consisting of 84 days of levonorgestrel (LNG)/ethinylestradiol (EE) 150 μg/30 μg tablets plus seven days of EE 10 μg tablets in place of placebo. This was a phase 1, open-label study. Ovarian follicular activity was classified via the Hoogland and Skouby method. Safety and tolerability as well as return to ovulation were assessed. Of the 35 subjects included in the efficacy analysis, luteinized, unruptured follicles, or ovulation were detected in 0 of 35 cycles during the first 28-day interval; 1 of 35 cycles (2.9%) in the second 28-day interval; and 2 of 35 cycles (5.7%) in the final 35-day interval. The ovarian activity rate over the entire 91-day treatment period was 2.9%. There was a low incidence of treatment-emergent adverse events. Ovulation returned in most subjects (77.1%, 27/35) within 32 days following the last dose of COC. The 91-day extended-regimen COC with low-dose EE supplementation was found to be effective in suppressing ovarian activity and inhibiting ovulation and was well tolerated. Return to ovulation was rapid, occurring within approximately one month after discontinuation of COC.

to evaluate the strategy for open heart surgery after renal transplantation performed in a single institution in Japan. we reviewed 6 open heart surgeries after renal transplantation in 5 patients, performed between January 1992 and December 2012. The patients were 3 men and 2 women with a mean age of 60 ± 11 years (range 46-68 years). They had old myocardial infarction and unstable angina, aortic and mitral stenosis, left arterial myxoma, aortic stenosis, and native valve endocarditis followed by prosthetic valve endocarditis. Operative procedures included coronary artery bypass grafting, double-valve replacement, resection of left arterial myxoma, 2 aortic valve replacements, and a double-valve replacement. Renal protection consisted of steroid cover (hydrocortisone 100-500 mg or methylprednisolone 1000 mg) and intravenous immunosuppressant infusion (cyclosporine 30-40 mg day(-1) or tacrolimus 1.0 mg day(-1)). 5 cases were uneventful and good renal graft function was maintained at discharge (serum creatinine 2.1 ± 0.5 mg dL(-1)). There was one operative death after emergency double-valve replacement for methicillin-resistant Staphylococcus aureus-associated prosthetic valve endocarditis. Although the endocarditis improved after valve replacement, the patient died of postoperative pneumonia on postoperative day 45. careful perioperative management can allow successful open heart surgery after renal transplantation. However, severe complications, especially methicillin-resistant Staphylococcus aureus infection, may cause renal graft loss. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Background Major abdominal surgery (MAS) is high-risk intervention usually accompanied by tissue injury leading to a release of signaling danger molecules called alarmins. This study evaluates the surgical injury caused by two fundamental types of gastrointestinal surgical procedures (open surgery and laparoscopy) in relation to the inflammation elicited by alarmins. Patients and methods Patients undergoing MAS were divided into a mixed laparoscopy group (LPS) and an open surgery group (LPT). Serum levels of alarmins (S100A8, S100A12, HMGB1, and HSP70) and biomarkers (leukocytes, C-reactive protein [CRP], and interleukin-6 [IL-6]) were analyzed between the groups. The secondary objectives were to compare LPT and LPS cancer subgroups and to find the relationship between procedure and outcome (intensive care unit length of stay [ICU-LOS] and hospital length of stay [H-LOS]). Results A total of 82 patients were analyzed. No significant difference was found in alarmin levels between the mixed LPS and LPT groups. IL-6 was higher in the LPS group on day 2 (p=0.03) and day 3 (p=0.04). Significantly higher S100A8 protein levels on day 1 (p=0.02) and day 2 (p=0.01) and higher S100A12 protein levels on day 2 (p=0.03) were obtained in the LPS cancer subgroup. ICU-LOS and H-LOS were longer in the LPS cancer subgroup. Conclusion The degree of surgical injury elicited by open MAS as reflected by alarmins is similar to that of laparoscopic procedures. Nevertheless, an early biomarker of inflammation (IL-6) was higher in the laparoscopy group, suggesting a greater inflammatory response. Moreover, the levels of S100A8 and S100A12 were higher with a longer ICU-LOS and H-LOS in the LPS cancer subgroup. PMID:29881282

Alterations in the composition of the gut microbiome and/or immune system function may have a role in the development of autism spectrum disorders (ASD). The current study examined the effects of prenatal and early life administration of lipopolysaccharide (LPS), a bacterial mimetic, and the short chain fatty acid, propionic acid (PPA), a metabolic fermentation product of enteric bacteria, on developmental milestones, locomotor activity, and anxiety-like behavior in adolescent male and female offspring. Pregnant Long-Evans rats were subcutaneously injected once a day with PPA (500 mg/kg) on gestation days G12–16, LPS (50 µg/kg) on G15–16, or vehicle control on G12–16 or G15–16. Male and female offspring were injected with PPA (500 mg/kg) or vehicle twice a day, every second day from postnatal days (P) 10–18. Physical milestones and reflexes were monitored in early life with prenatal PPA and LPS inducing delays in eye opening. Locomotor activity and anxiety were assessed in adolescence (P40–42) in the elevated plus maze (EPM) and open-field. Prenatal and postnatal treatments altered behavior in a sex-specific manner. Prenatal PPA decreased time spent in the centre of the open-field in males and females while prenatal and postnatal PPA increased anxiety behavior on the EPM in female rats. Prenatal LPS did not significantly influence those behaviors. Evidence for the double hit hypothesis was seen as females receiving a double hit of PPA (prenatal and postnatal) displayed increased repetitive behavior in the open-field. These results provide evidence for the hypothesis that by-products of enteric bacteria metabolism such as PPA may contribute to ASD, altering development and behavior in adolescent rats similar to that observed in ASD and other neurodevelopmental disorders.

Pancreatic mucinous cystic neoplasms (MCNs) are rare tumors typically of the distal pancreas that harbor malignant potential. Although resection is recommended, data are limited on optimal operative approaches to distal pancreatectomy for MCN. MCN resections (2000-2014; eight institutions) were included. Outcomes of minimally invasive and open MCN resections were compared. A total of 289 patients underwent distal pancreatectomy for MCN: 136(47%) minimally invasive and 153(53%) open. Minimally invasive procedures were associated with smaller MCN size (3.9 vs 6.8 cm; P = 0.001), lower operative blood loss (192 vs 392 mL; P = 0.001), and shorter hospital stay(5 vs 7 days; P = 0.001) compared with open. Despite higher American Society of Anesthesiologists class, hand-assisted (n = 46) had similar advantages as laparoscopic/robotic (n = 76). When comparing hand-assisted to open, although MCN size was slightly smaller (4.1 vs 6.8 cm; P = 0.001), specimen length, operative time, and nodal yield were identical. Similar to laparoscopic/robotic, hand-assisted had lower operative blood loss (161 vs 392 mL; P = 0.001) and shorter hospital stay (5 vs 7 days; P = 0.03) compared with open, without increased complications. Hand-assisted laparoscopic technique is a useful approach for MCN resection because specimen length, lymph node yield, operative time, and complication profiles are similar to open procedures, but it still offers the advantages of a minimally invasive approach. Hand-assisted laparoscopy should be considered as an alternative to open technique or as a successive step before converting from total laparoscopic to open distal pancreatectomy for MCN.

The purpose of the present study was to compare the perioperative and oncologic outcomes between laparoscopic surgery and open surgery for transverse colon cancer. We conducted a retrospective review of patients who underwent surgery for transverse colon cancer at six Hallym University-affiliated hospitals between January 2005 and June 2015. The perioperative outcomes and oncologic outcomes were compared between laparoscopic and open surgery. Of 226 patients with transverse colon cancer, 103 underwent laparoscopic surgery and 123 underwent open surgery. There were no differences in the patient characteristics between the two groups. Regarding perioperative outcomes, the operation time was significantly longer in the laparoscopic group than in the open group (267.3 vs 172.7 minutes, P<0.001), but the time to soft food intake (6.0 vs 6.6 days, P=0.036) and the postoperative hospital stay (13.7 vs 15.7 days, P=0.018) were shorter in the laparoscopic group. The number of harvested lymph nodes was lower in the laparoscopic group than in the open group (20.3 vs 24.3, P<0.001). The 5-year overall survival (90.8% vs 88.6%, P=0.540) and disease-free survival (86.1% vs 78.9%, P=0.201) rates were similar in both groups. The present study showed that laparoscopic surgery is associated with several perioperative benefits and similar oncologic outcomes to open surgery for the resection of transverse colon cancer. Therefore, laparoscopic surgery offers a safe alternative to open surgery in patients with transverse colon cancer.

The laparoscopic repair of Morgagni's hernia (MH) has been reported to be safe and feasible. However, it is still unclear whether laparoscopy is superior to open surgery in repairing MH. Using a defined search strategy, three investigators independently identified all comparative studies reporting data on open and laparoscopic MH repair in patients <18 years of age. Case reports and opinion articles were excluded. Meta-analysis was conducted according to PRISMA guidelines and using RevMan 5.3. Data are expressed as mean ± SD. Systematic review - Of 774 titles/abstracts screened, 51 full-text articles were analyzed. Three studies were included (92 patients), with 53 (58%) open approaches and 39 (42%) laparoscopy. Meta-analysis - The length of surgery was shorter in laparoscopy (50.5 ± 17.0 min) than in open procedure (90.0 ± 15.0 min; P < .00001). Laparoscopy shortened the length of hospital stay (2.1 ± 1.4 days) versus open surgery (4.5 ± 2.1 days; P < .00001). There was no difference with regards to complications (laparoscopy: 8.8% ± 5.5%, open: 9.4% ± 1.6%; P = .087) and recurrences (laparoscopy: 2.9% ± 5.0%, open: 5.7% ± 1.8%; P = .84). Comparative studies indicate that laparoscopic MH repair can be performed in infants and children. Laparoscopy is associated with shortened length of surgery and hospital stay in comparison to open procedure. Prospective randomized studies would be needed to confirm present data.

Laparoscopic colectomy has been shown to be safe, oncologically comparable, and clinically beneficial over open colectomy for colon cancer, but utilization remains low. Objectives To evaluate the cost of laparoscopic colectomy vs open colectomy for colon cancer. The authors conducted a retrospective claims data analysis using the 2012 and 2013 Truven Health Analytics MarketScan Commercial Claims and Encounter Database. The denominator population consisted of individuals who had commercial insurance coverage in all months of 2012 and >1 month in 2013 and pharmacy coverage throughout eligibility. The study population included individuals aged 18-64 years who were identified with colon cancer in 2013 and underwent an elective inpatient open colectomy or laparoscopic colectomy between January and November 2013. The cost and re-admission rate of open vs laparoscopic colectomy were compared after risk, adjusting for comorbidities, demographics, and geographic region. During the study period, 1299 elective inpatient colon cancer colectomies were performed (open, n = 558; laparoscopic, n = 741). After risk adjustment, the laparoscopic vs open group was shown to have lower re-admission rates (6.61 and 10.93 per 100 cases, respectively, p = .0165), lower average re-admission costs ($1676 and $3151, respectively, p = .0309), and lower 30-day post-discharge healthcare utilization costs ($4842 and $7121, respectively, p = .0047). Average allowed cost for the combined inpatient and 30-day post-discharge period was lower for laparoscopic vs open colectomy cases ($36,395 and $44,226, respectively, p < .001). The cost of laparoscopic colectomy was found to be statistically significantly less than that of open colectomy in patients undergoing elective surgery for colon cancer.

Moderate (body mass index [BMI] ≥30) and morbid obesity (BMI ≥35) is increasing at an alarming rate in vascular surgery patients. The objective of this study was to determine the impact of obesity on perioperative and long-term clinical outcomes following open abdominal aortic aneurysm (AAA) repair or endovascular aneurysm repair (EVAR). This review includes patients that underwent open AAA repair (n = 403) or EVAR (n = 223) from 1999 to 2009. Specific patient characteristics such as comorbid diseases, medications, and body mass index (BMI) were assessed. Specific perioperative outcomes such as length of stay, myocardial infarctions, and mortality were reviewed. In addition, long-term outcomes such as rates of reintervention, permanent renal dysfunction, and mortality beyond 30 days were also assessed. The incidence of obesity in open AAA patients was 25.3% (documented incidence 1.5%) and for EVAR was 24.6% (documented incidence 4%). Moderate and morbid obesity was associated with longer intensive care unit (ICU) admissions for both open AAA or EVAR patients (P < .05). However, no significant differences in perioperative outcomes in terms of overall length of stay, myocardial infarction, acute renal failure, wound infections, or mortality were noted between obese and nonobese patients underoing open AAA repair or EVAR (P > .05). Similarly, moderate and morbid obesity was not associated with significant differences in rates of reintervention, permanent renal dysfunction, and mortality beyond 30 days for patients undergoing open AAA repair or EVAR (P > .05). The results of this study indicate that moderate and morbid obesity are not independently associated with adverse perioperative and long-term clinical outcomes for patients undergoing open AAA repair or EVAR. Therefore, either open AAA repair or EVAR can be accomplished safely in moderately obese and morbidly obese patients.

Introduction The open prosthetic repair of inguinal hernias under local anaesthesia (LA) is well established, with the concept of intraoperative 'pre-emptive analgesia' evolving so that patients are as comfortable as possible. We used a peri-incisional LA solution in patients undergoing day-case inguinal hernioplasty under general anaesthesia (GA) and recorded use of analgesia in the immediate postoperative period. Methods In this observational cohort study, 100 consecutive unselected men underwent open inguinal hernia repair as a day case. Of these, 75 underwent repair under GA and 25 with peri-incisional LA solution (equal mixture of 0.5% bupivacaine and 1% lignocaine with 1:200,000 adrenaline). Analgesia prescribed at induction, for maintenance and after cessation of anaesthesia was scored in accordance with the World Health Organization (WHO) analgesic ladder. Results The median age in the GA group was 59 years (range: 25-89 years) and in the GA+LA group, it was 62 years (range: 27-88 years). Of the 100 patients, 82 underwent a mesh plug repair by seven surgeons whereas 18 underwent a flat (Lichtenstein) mesh repair by two surgeons. WHO analgesic induction and postoperative scores were significantly lower in the GA+LA group (p=0.034 and p<0.001 respectively). There was also a significant difference in use of postoperative antiemetics (23% vs 0% in the GA only and GA+LA cohorts respectively, p=0.020). Six patients (8%) in the GA group failed day-case discharge criteria. Conclusions Patients undergoing contemporary day-case GA inguinal hernioplasty with pre-emptive LA solution infiltration require lower levels of postoperative opioid analgesia and antiemetics. These cases are less likely to fail discharge criteria for planned day surgery.

Purpose Colostomy creation is an essential procedure for colorectal surgeons, but the preferred method of colostomy varies by surgeon. We compared the outcomes of trephine colostomy creation with open those for the (laparotomy) and laparoscopic methods and evaluated appropriate indications for a trephine colostomy and the advantages of the technique. Methods We retrospectively evaluated 263 patients who had undergone colostomy creation by trephine, open and laparoscopic approaches between April 2006 and March 2016. We compared the clinical features and the operative and postoperative outcomes according to the approach used for stoma creation. Results One hundred sixty-three patients (62%) underwent colostomy surgery for obstructive causes and 100 (38%) for fistulous problems. The mean operative time was significantly shorter with the trephine approach (trephine, 46.0 ± 1.9 minutes; open, 78.7 ± 3.9 minutes; laparoscopic, 63.5 ± 5.0 minutes; P < 0.001), as was the time to flatus (1.8 ± 0.1 days, 2.1 ± 0.1 days, 2.2 ± 0.3 days, P = 0.025). Postoperative complications (<30 days) were not different among the 3 approaches (trephine, 4.3%; open, 1.2%; laparoscopic, 0%; P = 0.828). In patients who underwent rectal surgery, a trephine colostomy was feasible for a diversion colostomy (P < 0.001). Conclusion The trephine colostomy is safe and can be implemented quickly in various situations, and compared to other colostomy procedures, the patient’s recovery is faster. Previous laparotomy history was not a contraindication for a trephine colostomy, and a trephine transverse colostomy is feasible for patients who have undergone previous rectal surgery.

2007-11-01

The effects of the organophosphate insecticide chlorpyrifos on 5min open-field activity were examined in a 7-15 days old chick model. Chlorpyrifos was acutely administered taking into account cholinesterase inhibition and determination of the acute (24h) median lethal dose (LD50). The oral LD50 value of chlorpyrifos in chicks was 18.14mg/kg, with cholinergic toxicosis observed on intoxicated chicks. Chlorpyrifos at the dose rates of 5,10 and 20mg/kg orally produced within 2h signs of cholinergic toxicosis in the chicks and significantly inhibited plasma (40-70%), whole brain (43-69%) and liver (31-46%) cholinesterase activities in a dose-dependent manner. Chlorpyrifos at 2 and 4mg/kg, orally did not produce overt signs of cholinergic toxicosis, but decreased (30, 60 and 90min after dosing) the general locomotor activity of the chicks as seen by a significant increase in the latency to move from the central square of the open-field arena, decreases in the numbers of lines crossed and vocalization score. Repeated daily chlorpyrifos treatments (2 and 4mg/kg, orally) for seven consecutive days also caused hypoactivity in chicks in the open-field behavioral paradigm. Only the high dose of chlorpyrifos (4mg/kg, orally) given repeatedly for 7 days caused significant cholinesterase inhibition in the whole brain (37%) and the liver (22%). In conclusion, chlorpyrifos at single or short-term repeated doses-induced behavioral changes in 7-15 days old chicks, in a model that could be used for further neurobehavioral studies involving subtle effects of organophosphates on chicks.

Laparoscopic treatment of pancreatic pseudocyst allows for definitive drainage with faster recovery. Although many groups have reported their experience with an anterior approach, only a few have done so with a posterior approach. This paper compares the approaches, analyzing their potential benefits and pitfalls. Seven females and one male underwent laparoscopic cystgastrostomy to treat pancreatic pseudocysts. The anterior approach was performed by opening the stomach anteriorly, localizing the pseudocyst ultrasonographically, draining the cyst with a needle and, via the same opening, using a stapler to form a cystgastrostomy. The posterior approach was performed by directly visualizing the posterior gastric wall and the pseudocyst, opening and draining the cyst with a needle, and using a stapler and running sutures for closure. All patients had gallstone pancreatitis. Cystgastrostomy via the anterior approach was used in 4 patients and via the posterior approach in 4 patients. Dense adhesions required one attempted posterior cystgastrostomy to be converted to an anterior approach. The mean age of the anterior group was 38 years (range, 18-58 years) and hospital stay was 6 days (range, 4-8 days): for the posterior group, mean age was 42 years (range, 40-44 years) and length of stay was 3 days (range, 2-4 days). Although both approaches had good results with no complications and short hospital stays, the posterior approach is safer, with a more precise cyst visualization and dissection that permits more tissue to be sent for histopathologic examination. Furthermore, the posterior approach?s larger anastomosis would seem to yield fewer occlusions, which are commonly seen with the anterior approach. The anterior approach is easier to learn, but it requires the opening of the anterior stomach and the use of ultrasound.

Physiological responses of the Crassulacean acid metabolism (CAM) plant Opuntia ficus-indica (Cactaceae) were studied on a commercial plantation in central Chile. Young cladodes (flattened stems) and flower buds exhibited daytime stomatal opening, whereas mature cladodes and fruit exhibited the nocturnal stomatal opening characteristic of CAM plants. Severe water stress suppressed the nocturnal stomatal opening by mature cladodes, but their high water vapor conductance occurring near dawn was not affected. Nocturnal acidity increases were not as sensitive to water stress as was the nocturnal stomatal opening. The magnitude of the nocturnal acidity increases depended on the total daily photosynthetically active radiation (PAR), being 90% PAR-saturated at 27 moles per square meter per day for a mean nighttime air temperature of 5 degrees C and at 20 moles per square meter per day for 18 degrees C. Inasmuch as the PAR received on unshaded vertical surfaces averaged about 21 moles per square meter per day, nocturnal acidity increases by the cladodes were on the verge of being PAR-limited in the field. The net assimilation rate, which was positive throughout the year, annually averaged 3.4 grams per square meter per day for 1.0- and 2.0-year-old plants. Plants that were 5.4 years old had 7.2 square meters of cladode surface area (both sides) and an annual dry weight productivity of 13 megagrams (metric tons) per hectare per year when their ground cover was 32%. This substantial productivity for a CAM plant was accompanied by the highest nocturnal acidity increase so far observed in the field, 0.78 mole H(+) per square meter.

Epidemiological studies have demonstrated the adverse effects of particulate matter (PM) inhalation on the respiratory and cardiovascular systems. It has been reported that air pollution may affect the central nervous system and decrease cognitive function. In rats, residual oil fly ash (ROFA) instillation causes decreased motor activity and increased lipid peroxidation in the striatum and the cerebellum. Our objective was to determine whether chronic instillation of particles induces changes in learning and memory in rats and whether oxidants in the hippocampus may contribute to these adverse effects. Forty-five-day-old male Wistar rats were exposed to ROFA by intranasal instillation and were treated with N-acetylcysteine (NAC) at 150 mg/kg i.p. for 30 days. Control groups were exposed to ROFA, NAC, or neither. On days 1, 8, and 30 of the protocol, rats were submitted to the open field test to evaluate habituation. After the last open field session, the rats were killed by decapitation. The hippocampus was used to determine lipid peroxidation (LP) by the thiobarbituric acid-reactive substances test. ROFA instillation induced an increase in LP in the hippocampus compared to all treatment groups (p = .012). NAC treatment blocked these changes. All of the treatment groups presented a decrease in the frequency of peripheral walking (p = .001), rearing (p = .001), and exploration (p = .001) over time. Our study demonstrates that exposure to particles for 30 days and/or NAC treatment do not modify habituation to an open field, a simple form of learning and memory in rats, and that oxidative damage induced by ROFA does not modulate these processes.

Objective: To compare the clinical effects of robot-assisted minimally invasive transforaminal lumbar interbody fusion (TLIF) and traditional open TLIF in the treatment of lumbar spondylolisthesis. Methods: A total of 41 patients with lumbar spondylolisthesis accepted surgical treatment in Department of Spinal Surgery of Beijing Jishuitan Hospital From July 2015 to April 2016 were retrospectively analyzed. There were 16 cases accepted robot-assisted minimally invasive TLIF and 25 accepted traditional open TLIF. The operation time, X-ray radiation exposure time, perioperative bleeding, drainage volume, time of hospitalization, time for pain relief, time for ambulatory recovery, visual analogue scale (VAS), Oswestry disability index (ODI) and complications were compared. T test and χ(2) were used to analyze data. Results: There were no significant difference in gender, age, numbers, degrees, pre-operative VAS and ODI in spondylolisthesis (all P >0.05). Compared with traditional open TLIF group, the robot-assisted minimally invasive TLIF group had less perioperative bleeding ((187.5±18.4) ml vs . (332.1±23.5) ml), less drainage volume ((103.1±15.6) ml vs . (261.3±19.8) ml), shorter hospitalization ((7.8±1.9) days vs . (10.0±1.6) days), shorter time for pain relief ((2.8±1.0) days vs . (5.2±1.1) days), shorter time for ambulatory recovery ((1.7±0.9) days vs . (2.9±1.3) days) and less VAS of the third day postoperatively (2.2±0.9 vs . 4.2±2.4) ( t =2.762-16.738, all P <0.05), but need more operation time ((151.3±12.3) minutes vs . (102.2±7.1) minutes) and more X-ray radiation exposure ((26.1±3.3) seconds vs . (5.5±2.1) seconds) ( t =6.125, 15.168, both P <0.01). In both groups ODI was significantly lower in final follow-up than that of the pre-operation ( t =12.215, 14.036, P <0.01). Intervertebral disc height of the final follow-up in both groups were significantly larger than that of the preoperation (robot-assisted minimally invasive TLIF group: (11.8 ± 2.8) mm vs . (7.5 ± 1.9) mm, traditional open TLIF group: (12.7 ± 2.5) mm vs . (7.9±2.0) mm), and so was the lumbar lordosis angle (robot-assisted minimally invasive TLIF group: (48.7±9.2)° vs . (39.6±7.9)°, traditional open TLIF group: (50.1±10.8)° vs . (41.4±8.8)°), the lordosis angle of the slippage segment (robot-assisted minimally invasive TLIF group: (18.7±5.6)° vs . (10.9±3.8)°, traditional open TLIF group: (17.6±6.1)° vs .(8.7±3.2)°) ( t =4.128-16.738, all P <0.01). Slippage rate of the final follow-up in both groups were significantly smaller than those of the pre-operation (robot-assisted minimally invasive TLIF group: (5.3±2.3) % vs . (27.8±7.2) %, traditional open TLIF group: (6.6±2.8) % vs . (29.1±9.5) %) ( t =11.410, 18.504, both P <0.01). There was no difference of the upper data between two groups ( t =0.106-1.227, P >0.05). The results of the post-operative CT showed that the pedicle screws in the robot-assisted minimally invasive TLIF group were more precisely placed than traditional open TLIF group (χ(2)=4.247, P =0.039). The mean follow-up time was 8 months (ranging from 3 to 12 months). There were no significant difference in outcomes between the two groups (χ(2)=0.366, P =0.545). Conclusions: In the treatment of lumbar spondylolisthesis, Robot-assisted minimally invasive TLIF can lead to less perioperative bleeding, less post-operative pain, and quicker recovery than traditional open TLIF surgery, but it needs more operation time and radiation exposure.

Endoscopic bursectomy for the treatment of septic pre-patellar bursitis: a case series.

2012-07-01

Operative treatment for septic pre-patellar bursitis generally involves open debridement in addition to an extended course of intravenous antibiotics. Skin necrosis and wound breakdown are potential complications of this procedure in addition to scar sensitivity and a prolonged recovery. We report endoscopic bursectomy for the treatment of septic pre-patellar bursitis in eight patients over a 3-year period. All patients had microbiological confirmation of an infective process. The average age was 36 years (23-68 years). The average hospital stay was 6 days (4-9 days). No patient had a recurrence or complained of tenderness or hypoaesthesia around their wound. No patient experienced wound complications or skin necrosis. The average return to work time was 18 days (7-22 days). We conclude that endoscopic bursectomy is a safe and effective treatment for septic pre-patellar bursitis with a shortened hospital stay and a quicker return to work than conventional open debridement.

The length of construct can potentially influence perioperative risks in adult spinal deformity (ASD) surgery. A head-to-head comparison between open and minimally invasive surgery (MIS) techniques for treatment of ASD has yet to be performed. To examine the impact of MIS approaches on construct length and clinical outcomes in comparison to traditional open approaches when treating similar ASD profiles. Two multicenter databases for ASD, 1 involving MIS procedures and the other open procedures, were propensity matched for clinical and radiographic parameters in this observational study. Inclusion criteria were ASD and minimum 2-year follow-up. Independent t -test and chi-square test were used to evaluate and compare outcomes. A total of 1215 patients were identified, with 84 patients matched in each group. Statistical significance was found for mean levels fused (4.8 for circumferential MIS [cMIS] and 10.1 for open), mean interbody fusion levels (3.6 cMIS and 2.4 open), blood loss (estimated blood loss 488 mL cMIS and 1762 mL open), and hospital length of stay (6.7 days cMIS and 9.7 days open). There was no significant difference in preoperative radiographic parameters or postoperative clinical outcomes (Owestry Disability Index and visual analog scale) between groups. There was a significant difference in postoperative lumbar lordosis (43.3° cMIS and 49.8° open) and pelvic incidence-lumbar lordosis correction (10.6° cMIS and 5.2° open) in the open group. There was no significant difference in reoperation rate between the 2 groups. MIS techniques for ASD may reduce construct length, reoperation rates, blood loss, and length of stay without affecting clinical and radiographic outcomes when compared to a similar group of patients treated with open techniques.

The N-Methyl-D-Aspartate (NMDA) receptor is expressed abundantly in the brain and plays an important role in neuronal development, learning and memory, neurodegenerative diseases, and neurogenesis. In this study, we evaluated the effects of NMDA receptor blockade during the early neurodevelopmental period on exploratory locomotion, anxiety-like behaviors and cognitive functions of adolescent Wistar rats. NMDA receptor hypofunction was induced 7-10 days after birth using MK-801 in rats (0.25 mg/kg twice a day for 4 days via intraperitoneal injection). The open-field (OF), elevated plus maze (EPM) and passive avoidance (PA) tests were used to evaluate exploratory locomotion, anxiety-like behaviors and cognitive functions. In the OF test, MK-801 caused an increase in locomotion behavior (p < 0.01) and in the frequency of rearing (p < 0.05). In the EPM test, MK-801 treatment increased the time spent in the open arms, the number of open arm entries and the amount of head dipping (p < 0.01). MK-801 treatment caused no statistical difference compared to the control group in the PA test (p > 0.05). Chronic NMDA receptor blockade during the critical period of maturation for the glutamatergic brain system (postnatal days 7-10) produces locomotor hyperactivity and decreased anxiety levels, but has no significant main effect on cognitive function during adolescence.

Wound dressing materials such as asiaticoside, collagenase, and alpha-chymotrypsin are often used for effective wound healing activity. In this study, the effects of asiaticoside, collagenase, and alpha-chymotrypsin were studied in rabbit models with open wounds with tissue loss and with full-thickness flank excisions for a period of 21 days. Three groups of 4 rabbits were examined during trial periods of 7, 14, and 21 days. Four circular wounds measuring 1.5 cm in diameter were made on the dorsal sides of the animals: 2 on the right and 2 the left. Asiaticoside, collagenase, and alpha-chymotrypsin were applied to wounds daily for a period of 7, 14, and 21 days, while 1 gauzed wound served as the control. All biopsy specimens were histopathologically evaluated for recovery. On day 7, microscopic review showed no differences in wound healing between groups. By day 14, alpha-chymotrypsin showed the quickest reepithelialization (P < 0.05); and by day 21 asiaticoside and collagenase (P < 0.01) showed effective recovery, due to the completion of wound healing for all animals in both groups. Alpha-chymotrypsin is more effective than the other 2 groups for only 14 days. The effectiveness of asiaticoside and collagenase displayed a more rapid improvement in comparison to alpha-chymotrypsin for healing open wounds with tissue loss for a period of 21 days.

Defect nonunion of a metatarsal bone fracture in a cow: successful management with bone plating and autogenous cancellous bone graft.

A two-and-half-year-old cow was presented with a defect nonunion of the right metatarsal III/IV bone following a severely comminuted open fracture two months previously. The animal underwent open fixation using a 4.5 mm, broad, 10-hole, dynamic compression plate and autogenous cancellous bone graft collected from the contralateral iliac shaft. The animal started partial weight bearing after the third postoperative day and resumed complete weight bearing after the 10th day. Fracture healing was complete and the implants were removed after the 120th postoperative day. Stable fixation by means of a bone plate in conjunction with a cancellous bone graft facilitated complete healing and restoration of the bone column of the defect and the metatarsal fracture. The animal made a complete recovery.

2016-02-01

Both open and closed loop self-expandable stents were used in carotid artery stenting (CAS) for carotid bifurcation stenosis. We sought to compare the efficacy of two types of stents in CAS. The data of 212 patients treated with CAS (42 and 170 cases implanted with closed and open loop stents, respectively) for carotid bifurcation stenosis and distal filtration protection devices were retrospectively analyzed. Between closed and open loop stents, there were no significant differences in hospitalization duration, NIHSS score before and after the treatment, stenosis at 12th month, and cumulative incidence of primary endpoint events within 30 days or from the 31st day to the 12th month; while there were significant differences in hemodynamic changes and rate of difficulty in recycling distal filtration protection devices. Use of open vs. closed loop stents for carotid bifurcation stenosis seems to be associated with similar incidence of complications, except for greater rate of hemodynamic changes and lower rate of difficulty in recycling the distal filtration protection devices.

The hypothesis was tested that the new open-group Norwegian day-care centers would more than traditionally organized centers negatively affect (a) current and (b) future teacher-child relationships, and (c) the developmental legacy of preschool problem behavior. The focus was on eight hundred and fifty 4-year-olds from 153 centers who were followed up in first grade. Results of this natural quasi-experiment revealed that children from open-group centers (a) experienced less teacher-child closeness in preschool and (b) more teacher-child conflict in first grade, and (c) that high levels of preschool problem behavior forecast especially high levels of future teacher-child conflict, but only for children from open-group centers. Results highlight the importance of spatial and social organization of day care and their translational implications. © 2015 The Authors.

Background Sleeping sickness (human African trypanosomiasis [HAT]) is caused by protozoan parasites and characterized by a chronic progressive course, which may last up to several years before death. We conducted two Phase 2 studies to determine the efficacy and safety of oral pafuramidine in African patients with first stage HAT. Methods The Phase 2a study was an open-label, non-controlled, proof-of-concept study where 32 patients were treated with 100 mg of pafuramidine orally twice a day (BID) for 5 days at two trypanosomiasis reference centers (Angola and the Democratic Republic of the Congo [DRC]) between August 2001 and November 2004. The Phase 2b study compared pafuramidine in 41 patients versus standard pentamidine therapy in 40 patients. The Phase 2b study was open-label, parallel-group, controlled, randomized, and conducted at two sites in the DRC between April 2003 and February 2007. The Phase 2b study was then amended to add an open-label sequence (Phase 2b-2), where 30 patients received pafuramidine for 10 days. The primary efficacy endpoint was parasitologic cure at 24 hours (Phase 2a) or 3 months (Phase 2b) after treatment completion. The primary safety outcome was the rate of occurrence of World Health Organization Toxicity Scale Grade 3 or higher adverse events. All subjects provided written informed consent. Findings/Conclusion Pafuramidine for the treatment of first stage HAT was comparable in efficacy to pentamidine after 10 days of dosing. The cure rates 3 months post-treatment were 79% in the 5-day pafuramidine, 100% in the 7-day pentamidine, and 93% in the 10-day pafuramidine groups. In Phase 2b, the percentage of patients with at least 1 treatment-emergent adverse event was notably higher after pentamidine treatment (93%) than pafuramidine treatment for 5 days (25%) and 10 days (57%). These results support continuation of the development program for pafuramidine into Phase 3. PMID:26881924

Sleeping sickness (human African trypanosomiasis [HAT]) is caused by protozoan parasites and characterized by a chronic progressive course, which may last up to several years before death. We conducted two Phase 2 studies to determine the efficacy and safety of oral pafuramidine in African patients with first stage HAT. The Phase 2a study was an open-label, non-controlled, proof-of-concept study where 32 patients were treated with 100 mg of pafuramidine orally twice a day (BID) for 5 days at two trypanosomiasis reference centers (Angola and the Democratic Republic of the Congo [DRC]) between August 2001 and November 2004.

[DL-phenylalanine as an antidepressant. Open study (author's transl)].

PubMed

Beckmann, H; Ludolph, E

1978-01-01

In an open study dl-phenylalanine in doses from 75--200 mg/day was administered to 20 depressed patients for 20 days. At the end of the trial 12 patients (8 with complete, 4 with good response) could be discharged without any further treatment. 4 patients with partially untypical depressions experienced mild to moderate responses, whereas 4 patients did not respond at all to the phenylalanine administration. Depressive "core symptoms" as depressed mood, retardation and/or agitation were preferentially, anxiety and sleep disturbances moderately and hypochondriasis and compulsiveness were not influenced. It is concluded that dl-phenylalanine might have substantial antidepressant properties and that further controlled investigations are justified.

Summer behavior of immature radio-equipped woodcock in central Maine

1973-01-01

The behavior of 15 immature American woodcock (Philohela minor) was studied in central Maine during the summers of 1969 and 1970 using radiotelemetry. The monitored birds used a variety of nocturnal sites including old fields, bogs, powerlines, highway medians, woods roads, and fore clearings. Old fields were occupied more often than any other type of opening. Second growth-hardwoods, alders, hardwood-conifers, and conifers were utilized as diurnal cover. Diurnal locations of radio-equipped woodcock averaged 15 m from major breaks in the forest canopy. Four birds were monitored continuously during the day and night to detennine periods of activity. Although the birds were active throughout the day, very little activity was recorded after they moved to nocturnal sites. No apparent difference was found in the daily patterns of movement between immature male and female woodcock. Crepuscular movements between diurnal covers and nocturnal areas averaged 332 m. A composite summer range for the 15 woodcock during 183 woodcock-days was 1060 hectares. The data suggest that immature woodcock are quite mobile during the summer and utilize most of the forest openings occurring within 1-3 km of good nesting habitat. Most of these openings are also used for singing grounds by males in the spring.

Application of simplified bioclean apparatuses for treatment of acute leukemia.

1983-01-01

We used a portable horizontal laminar-air-flow clean bed and an open horizontal laminar-air-flow fan (clean wall unit) for treating patients with acute leukemia. The level of cleanliness as shown in the nonviable and viable particle counts was class 100 and class 1,000 at the head and foot, respectively, of the bed in the clean-bed rooms, while it was class 100 and class 10,000 respectively, in the clean-wall-unit rooms. The level of cleanliness in the open wards, on the other hand, was class 1,000,000. The incidence of infectious complications in the clean-bed rooms was 3.1/100 days when the granulocyte count was 1,000/mm3 or less, 3.9/100 days when the count was 500/mm3 or less and 6.1/100 days when it was 100/mm3 or less. In the clean-wall-unit rooms, these values were 3.1, 3.7 and 7.1, respectively, while in the open wards they were 4.6, 6.1 and 15.0. Thus, it was ascertained that, as the granulocyte count decreased, the incidence of infectious complications became significantly higher in the open wards than in the clean-bed rooms or the clean-wall-unit rooms. No complication of pneumonia was found in 37 patients with acute leukemia in the clean-bed rooms or in 40 in the clean-wall-unit rooms. Among 36 patients treated in the open wards, on the other hand, the complication of pneumonia was found in four. From the above results, it is believed that the use of clean-bed rooms or clean-wall-unit rooms is an extremely effective supplementary treatment method for preventing respiratory tract infection complications in patients with acute leukemia.

Objectives Emergency endovascular aneurysm repair (eEVAR) may improve outcomes for patients with ruptured abdominal aortic aneurysm (RAAA). The study aim was to compare the outcomes for eEVAR with conventional open surgical repair for the treatment of RAAA. Setting A systematic review of relevant publications was performed. Randomised controlled trials (RCTs) comparing eEVAR with open surgical repair for RAAA were included. Participants 3 RCTs were included, with a total of 761 patients with RAAA. Interventions Meta-analysis was performed with fixed-effects models with ORs and 95% CIs for dichotomous data and mean differences with 95% CIs for continuous data. Primary and secondary outcome measures Primary outcome was short-term mortality. Secondary outcome measures included aneurysm-specific and general complication rates, quality of life and economic analysis. Results Overall risk of bias was low. There was no difference between the 2 interventions on 30-day (or in-hospital) mortality, OR 0.91 (95% CI 0.67 to 1.22; p=0.52). 30-day complications included myocardial infarction, stroke, composite cardiac complications, renal complications, severe bowel ischaemia, spinal cord ischaemia, reoperation, amputation and respiratory failure. Reporting was incomplete, and no robust conclusion was drawn. For complication outcomes that did include at least 2 studies in the meta-analysis, there was no clear evidence to support a difference between eEVAR and open repair. Longer term outcomes and cost per patient were evaluated in only a single study, thus precluding definite conclusions. Conclusions Outcomes between eEVAR and open repair, specifically 30-day mortality, are similar. However, further high-quality trials are required, as the paucity of data currently limits the conclusions. PMID:26873043

The first large-scale randomised trial (Immediate Management of the Patient with Rupture: Open Versus Endovascular repair [IMPROVE]) for endovascular repair of ruptured abdominal aortic aneurysm (rEVAR) has recently finished recruiting patients. The aim of this study was to examine the impact on survival after rEVAR when the IMPROVE protocol was initiated in a high volume abdominal aortic aneurysm (AAA) centre previously performing rEVAR. One hundred and sixty-nine patients requiring emergency infrarenal AAA repair from January 2006 to April 2013 were included. Eighty-four patients were treated before (38 rEVAR, 46 open) and 85 (31 rEVAR, 54 open) were treated during the trial period. A retrospective analysis was performed. Before the trial, there was a significant survival benefit for rEVAR over open repair (90-day mortality 13% vs. 30%, p = .04, difference remained significant up to 2 years postoperatively). This survival benefit was lost after starting randomisation (90-day mortality 35% vs. 33%, p = .93). There was an increase in overall 30-day mortality from 15% to 31% (p = .02), while there was no change for open repair (p = .438). There was a significant decrease in general anaesthetic use (p = .002) for patients treated during the trial. Randomised patients had shorter hospital and intensive treatment unit stays (p = .006 and p = .03 respectively). The change in survival seen during the IMROVE trial highlights the need for randomised rather than cohort data to eliminate selection bias. These results from a single centre reinforce those recently reported in IMPROVE. Copyright © 2014 European Society for Vascular Surgery. Published by Elsevier Ltd. All rights reserved.

Monosodium glutamate-associated alterations in open field, anxiety-related and conditioned place preference behaviours in mice.

2017-07-01

The present study investigated changes in behaviour associated with oral monosodium glutamate (a flavouring agent), using the open field, elevated plus maze and conditioned place preference (CPP) paradigms, respectively. Mice were assigned to two groups for CPP [monosodium glutamate (MSG)-naïve (n = 40) and MSG-pretreated (n = 40)] and two groups for open field (OF) and elevated plus maze (EPM) tests [n = 40 each], respectively. Animals in respective groups were then divided into four subgroups (n = 10) (vehicle or MSG (80, 160 and 320 mg/kg)). MSG-naïve mice were observed in the CPP box in three phases (pre-conditioning, conditioning and post-conditioning). Mice were conditioned to MSG or an equivalent volume of saline. The MSG pretreatment group received vehicle or respective doses of MSG daily for 21 days, prior to conditioning. Mice in the OF or EPM groups received vehicle or doses of MSG (orally) for 21 days, at 10 ml/kg. Open field or EPM behaviours were assessed on days 1 and 21. At the end of the experiments, mice in the OF groups were sacrificed and brain homogenates used to assay glutamate and glutamine. Results showed that administration of MSG was associated with a decrease in rearing, dose-related mixed horizontal locomotor, grooming and anxiety-related response and an increase in brain glutamate/glutamine levels. Following exposure to the CPP paradigm, MSG-naïve and MSG-pretreated mice both showed 'drug-paired' chamber preference. The study concluded that MSG (at the administered doses) was associated with changes in open field activities, anxiety-related behaviours and brain glutamate/glutamine levels; its ingestion also probably leads to a stimulation of the brain reward system.

Algal biofuels and valuable co-products are being produced in both open and closed cultivation systems. Growing algae in open pond systems may be a more economical alternative, but this approach allows environmental microorganisms to colonize the pond and potentially infect or outcompete the algal “crop.” In this study, we monitored the microbial community of an outdoor, open raceway pond inoculated with a high lipid-producing alkaliphilic alga, Chlorella vulgaris BA050. The strain C. vulgaris BA050 was previously isolated from Soap Lake, Washington, a system characterized by a high pH (~9.8). An outdoor raceway pond (200 L) was inoculated with C. vulgarismore » and monitored for 10 days and then the culture was transferred to a 2,000 L raceway pond and cultivated for an additional 6 days. Community DNA samples were collected over the 16-day period in conjunction with water chemistry analyses and cell counts. Universal primers for the SSU rRNA gene sequences for Eukarya, Bacteria, and Archaea were used for barcoded pyrosequence determination. The environmental parameters that most closely correlated with C. vulgaris abundance were pH and phosphate. Community analyses indicated that the pond system remained dominated by the Chlorella population (93% of eukaryotic sequences), but was also colonized by other microorganisms. Bacterial sequence diversity increased over time while archaeal sequence diversity declined over the same time period. Using SparCC co-occurrence network analysis, a positive correlation was observed between C. vulgaris and Pseudomonas sp. throughout the experiment, which may suggest a symbiotic relationship between the two organisms. The putative relationship coupled with high pH may have contributed to the success of C. vulgaris. As a result, the characterization of the microbial community dynamics of an alkaliphilic open pond system provides significant insight into open pond systems that could be used to control photoautotrophic biomass productivity in an open, non-sterile environment.« less

We examined a total of 246 patients subjected to coronary artery bypass grafting with the use of the great saphenous vein (GSV). The patients were subdivided into two groups. Group One (n=121) patients endured procurement of the great saphenous vein by a new endoscopic technique in an open system with the help of the equipment Karl Storz and electric dissector Ligasure. In Group Two (n=125) patients the vein was harvested by means of the traditional open method. In all patients we evaluated complications in the early postoperative period 13±2.5 days after the operation. The rate of relapsing angina pectoris in both Groups turned out to be low and did not differ (1.65% in Group One and 1.6% in Group Two). Patients of the both groups differed significantly by the incidence of postoperative complications on the lower limbs in the zone of procurement of the GSV (9.09% in Group One and 26.4% in Group Two, p=0.131). Group Two patients (open method of procurement of the GSV) were considerably more often found to have developed cases of lymphorrhoea, haematomas, disjunction of the sutures (21.6%) compared with Group One (endoscopic method) patients (3.3%) (p=0.167), which in 10.4% of cases required secondary surgical debridement of wounds in patients after the open harvest of the GSV. Eventually, the length of hospital stay for Group Two patients increased significantly (15 ± 4.5 days) compared with Group One patients (8±1.1 days) (p=0.361). Hence, the endoscopic method of harvesting the GSV in the open CO2 system makes it possible to obtain a good cosmetic effect on the lower limbs after the operation, to considerably decrease the complications rate, thus reducing the length of hospital stay.

Gupta, Prateek K; Sundaram, Abhishek; Kent, K Craig

2015-07-01

Although placement of an open iliac conduit for endovascular aortic aneurysm repair (EVAR) is generally felt to result in higher morbidity and mortality, published literature is scarce. Our objective was to assess 30-day outcomes after elective EVAR with an open iliac conduit using a multi-institutional database. Patients who underwent elective EVAR (n = 14,339) for abdominal aortic aneurysm were identified from the American College of Surgeons National Surgical Quality Improvement Program 2005 to 2011 database. Univariable and multivariable logistic regression analyses were performed. An open iliac conduit was used in 231 patients (1.6%), and the remainder had femoral exposure or percutaneous EVAR. Women comprised 32% of patients with iliac conduits in contrast to 17% of those without iliac conduits. Patients with iliac conduits were older and had a lower body mass index. Univariable analysis showed patients with open iliac conduits had a higher incidence of postoperative pneumonia (3.0% vs 1.1%), ventilator dependence (4.8% vs 1.0%), renal failure (3.0% vs 0.7%), cardiac arrest or myocardial infarction (5.2% vs 1.1%), return to the operating room (9.1% vs 3.7%), major morbidity (16.0 vs 6.6%), and death (3.0% vs 0.9%). On multivariable analysis, the use of open iliac conduits was associated with higher risk of 30-day mortality (odds ratio, 2.7; 95% confidence interval, 1.2-6.0) and 30-day major morbidity (odds ratio, 2.3; 95% confidence interval, 1.6-3.3). Patients with open iliac conduits for EVAR are more likely to be female and have higher postoperative morbidity and mortality. For patients with complex iliac artery disease, conduits are a viable alternative after EVAR to be performed, albeit at an increased risk. These data do suggest the need for lower-profile grafts and other alternative strategies for navigating complex iliac artery disease. Copyright © 2015 Society for Vascular Surgery.

Periadolescent ethanol vapor exposure persistently reduces measures of hippocampal neurogenesis that are associated with behavioral outcomes in adulthood.

Excessive alcohol consumption is prevalent among adolescents and may result in lasting neurobehavioral consequences. The use of animal models to study adolescent alcohol exposure has the advantage of allowing for the control necessary in order to evaluate the effects of ethanol on the brain and separate such effects from genetic background and other environmental insults. In the present study the effects of moderate ethanol vapor exposure, during adolescence, on measures of neurogenesis and behavioral measures were evaluated at two different times following ethanol withdrawal, in adulthood. The two groups of Wistar rats were both exposed to intermittent ethanol vapor (14 h on/10h off/day) for 35-36 days from PD 23 to PD 58 (average blood ethanol concentration: 163 mg%). In the first group, after rats were withdrawn from vapor they were subsequently assessed for locomotor activity, conflict behavior in the open field, and behaviors in the forced swim test (FST) and then sacrificed at 72 days of age. The second group of rats were withdrawn from vapor and injected for 5 days with Bromo-deoxy-Uridine (BrdU). Over the next 8 weeks they were also assessed for locomotor activity, conflict behavior in the open field, and behaviors in the FST and then sacrificed at 113/114 days of age. All rats were perfused for histochemical analyses. Ethanol vapor-exposed rats displayed hypoactivity in tests of locomotion and less anxiety-like and/or more "disinhibitory" behavior in the open field conflict. Quantitative analyses of immunoreactivity revealed a significant reduction in measures of neurogenesis, progenitor proliferation, as indexed by doublecortin (DCX), Ki67, and increased markers of cell death as indexed by cleaved caspase-3, and Fluoro-Jade at 72 days, and decreases in DCX, and increases in cleaved caspase-3 at 114 days in the ethanol vapor-exposed rats. Progenitor survival, as assessed by BrdU+, was reduced in the vapor-exposed animals that were sacrificed at 114 days. The reduction seen in DCX labeled in cell counts was significantly correlated with hypoactivity at 24h after withdrawal as well as less anxiety-like and/or more "disinhibitory" behavior in the open field conflict test at 2 and 8 weeks following termination of vapor exposure. These studies demonstrate that behavioral measures of disinhibitory behavior correlated with decreases in neurogenesis are all significantly and persistently impacted by periadolescent ethanol exposure and withdrawal in Wistar rats.

Casearia sylvestris is a medicinal plant traditionally used to treat snakebites, wounds, inflammation and gastric ulcers and scientific supports for have demonstrated its antitumor, antihyperlipidemic and antiparasitic properties. To assess the effects of a fraction with casearins (FC) on adult mice using classical experimental models of animal behavior and theoretical calculations to verify the interaction of Casearin X (Cas X) with neuron receptors. Animals divided in 6 groups (n=9/group) were intraperitoneally treated with vehicle (DMSO 4%), FC (2.5, 5, 10 and 25mg/kg/day) and diazepam (2mg/kg) for 7 days. Thirty minutes after the last dose of treatment, acute toxicity and behavioral experiments were performed. The highest dose of FC (25mg/kg/day) caused diarrhea, weight loss and death of one animal. Elevated plus maze test showed that lower doses [2.5mg/kg/day (36.4±5.1s) and 5mg/kg/day (43.9±6.2s)] increased the time spent in open arms (TSOA). Open field test revealed reduction in the number of crossings (54.9%, 51.1%, 48% and 67.7% for 2.5, 5, 10 and 25mg/kg/day, respectively) in all doses of FC studied and decrease of rearings at 25mg/kg/day (p<0.05). Computational calculations showed that the inhibition constant (Ki) for the Cas X-D 1 complex is up to 1000-fold more favourable than the Cas X-GABA A complex. All ∆G° values obtained for Cas X-D 1 complexes were more negative than those seen with Cas X-GABA A complexes. Findings indicate a probable anxiolytic action of the FC since it reduces the number of crossings and rearings and prolonged the time spent in open arms, without sedative and myorelaxant effects, probably due to the interaction of Cas X with dopaminergic system.

Sharma, Satish; Kim, Hyung Lae; Mohler, James L

2007-02-01

To determine whether radical prostatectomy requires urinary drainage. All patients with clinically localized prostate cancer had complete clinical and pathologic information recorded prospectively in a database. The criteria for omission of pelvic drainage were successful bladder neck preservation; urethrovesical anastomosis performed using 6 interrupted sutures in open cases or 12 continuous sutures in robotic cases; and a watertight urethrovesical anastomosis on irrigation. Most patients were discharged on the first or second postoperative day. The catheters were removed routinely on postoperative day 9. A pelvic drain was not placed in 78% of 325 consecutive patients. A drain was omitted in 73% of 225 open cases and 90% of 100 robotic cases. The recovery of continence and the complication rates were similar between the two groups with and without pelvic drainage. Complications occurred in 11% of the group with pelvic drainage and 6% in the group without pelvic drainage. In the past 2 years, 17 of 126 patients required pelvic drainage. The frequency of complications in robotic versus open procedures was similar (chi-square test, P >0.05). Pelvic drainage may be omitted after radical prostatectomy when the urethrovesical anastomosis is performed well. Drainage omission could contribute to shortened hospital stays and reduced costs, without added complications. These benefits can be extended safely to patients undergoing open or robotic radical prostatectomy.

The open government initiatives have provided tremendous data resources for the transportation system and emergency services in urban areas. This paper proposes a traffic simulation framework using high temporal resolution demographic data and real time open government data for evacuation planning and operation. A comparison study using real-world data in Seattle, Washington is conducted to evaluate the framework accuracy and evacuation efficiency. The successful simulations of selected area prove the concept to take advantage open government data, open source data, and high resolution demographic data in emergency management domain. There are two aspects of parameters considered in this study: usermore » equilibrium (UE) conditions of traffic assignment model (simple Non-UE vs. iterative UE) and data temporal resolution (Daytime vs. Nighttime). Evacuation arrival rate, average travel time, and computation time are adopted as Measure of Effectiveness (MOE) for evacuation performance analysis. The temporal resolution of demographic data has significant impacts on urban transportation dynamics during evacuation scenarios. Better evacuation performance estimation can be approached by integrating both Non-UE and UE scenarios. The new framework shows flexibility in implementing different evacuation strategies and accuracy in evacuation performance. The use of this framework can be explored to day-to-day traffic assignment to support daily traffic operations.« less

To prove that video-assisted thoracoscopic surgery in selected cases is an alternative to urgent thoracotomy following open chest trauma. Retrospective analysis of case reports of patients operated for open chest trauma during 1997-2002. Comparison of two methods of surgical treatment: urgent video-assisted thoracoscopy and urgent thoracotomy. Duration of drain presence in the pleural cavity, duration of postoperative treatment, pain intensity and cosmetic effect were evaluated. Data analysis was performed using SPSS statistical software. Statistical evaluation of differences between groups was performed using Mann-Whitney U test. The differences between groups were considered to be statistically significant when the probability of deviation was p<0.05. During 1997-2002, 121 patients with open chest trauma were operated. Thirty three patients underwent urgent video-assisted thoracoscopy, 88 patients were operated through thoracotomy incision: 69 due to isolated open chest trauma, 17 due to thoracoabdominal injury and 2 due to abdominothoracic injury. Almost thirteen percent (12.5%) of patients after urgent thoracotomy underwent urgent laparotomy due to damaged diaphragm and other organs of peritoneal cavity. Duration of drain presence in the pleural cavity after video-assisted thoracoscopy was 4.57 days and after urgent thoracotomy - 6.88 days (p<0.05). Duration of post-operative treatment after video-assisted thoracoscopy was 8.21 days and after urgent thoracotomy - 14.89 days (p<0.05). Amount of consumed non-narcotic analgesics after video-assisted thoracoscopy was 1056.98 mg and after urgent thoracotomy - 1966.70 mg (p<0.05). Video-assisted thoracoscopy is minimally invasive method of thoracic surgery allowing for the evaluation of the pathological changes in the lung, pericardium, diaphragm, mediastinum, thoracic wall and pleura, including the localization of these changes, and the type and severity of the injury. The number of early post-operative complications following video-assisted thoracoscopy is lower. Compared to operations through thoracotomy incision, video assisted thoracoscopies entail the shortening of the duration of drain presence in the pleural cavity and the duration of post-operative treatment. Video-assisted thoracoscopy should be performed on all patients with open chest trauma and stable hemodynamics and the respiration function. Video-assisted thoracoscopy is an informative diagnostic and treatment method allowing for the selection of patients for urgent thoracotomy.

Exposure to an open-field arena increases c-Fos expression in a distributed anxiety-related system projecting to the basolateral amygdaloid complex.

Anxiety states and anxiety-related behaviors appear to be regulated by a distributed and highly interconnected system of brain structures including the basolateral amygdala. Our previous studies demonstrate that exposure of rats to an open-field in high- and low-light conditions results in a marked increase in c-Fos expression in the anterior part of the basolateral amygdaloid nucleus (BLA) compared with controls. The neural mechanisms underlying the anatomically specific effects of open-field exposure on c-Fos expression in the BLA are not clear, however, it is likely that this reflects activation of specific afferent input to this region of the amygdala. In order to identify candidate brain regions mediating anxiety-induced activation of the basolateral amygdaloid complex in rats, we used cholera toxin B subunit (CTb) as a retrograde tracer to identify neurons with direct afferent projections to this region in combination with c-Fos immunostaining to identify cells responding to exposure to an open-field arena in low-light (8-13 lux) conditions (an anxiogenic stimulus in rats). Adult male Wistar rats received a unilateral microinjection of 4% CTb in phosphate-buffered saline into the basolateral amygdaloid complex. Rats were housed individually for 11 days after CTb injections and handled (HA) for 2 min each day. On the test day rats were either, 1) exposed to an open-field in low-light conditions (8-13 lux) for 15 min (OF); 2) briefly HA or 3) left undisturbed (control). We report that dual immunohistochemical staining for c-Fos and CTb revealed an increase in the percentage of c-Fos-immunopositive basolateral amygdaloid complex-projecting neurons in open-field-exposed rats compared with HA and control rats in the ipsilateral CA1 region of the ventral hippocampus, subiculum and lateral entorhinal cortex. These data are consistent with the hypothesis that exposure to the open-field arena activates an anxiety-related neuronal system with convergent input to the basolateral amygdaloid complex.

Purpose The purpose of the present study was to compare the perioperative and oncologic outcomes between laparoscopic surgery and open surgery for transverse colon cancer. Patients and methods We conducted a retrospective review of patients who underwent surgery for transverse colon cancer at six Hallym University-affiliated hospitals between January 2005 and June 2015. The perioperative outcomes and oncologic outcomes were compared between laparoscopic and open surgery. Results Of 226 patients with transverse colon cancer, 103 underwent laparoscopic surgery and 123 underwent open surgery. There were no differences in the patient characteristics between the two groups. Regarding perioperative outcomes, the operation time was significantly longer in the laparoscopic group than in the open group (267.3 vs 172.7 minutes, P<0.001), but the time to soft food intake (6.0 vs 6.6 days, P=0.036) and the postoperative hospital stay (13.7 vs 15.7 days, P=0.018) were shorter in the laparoscopic group. The number of harvested lymph nodes was lower in the laparoscopic group than in the open group (20.3 vs 24.3, P<0.001). The 5-year overall survival (90.8% vs 88.6%, P=0.540) and disease-free survival (86.1% vs 78.9%, P=0.201) rates were similar in both groups. Conclusion The present study showed that laparoscopic surgery is associated with several perioperative benefits and similar oncologic outcomes to open surgery for the resection of transverse colon cancer. Therefore, laparoscopic surgery offers a safe alternative to open surgery in patients with transverse colon cancer. PMID:27143915

Growing evidence supports the safety of a laparoscopic approach for patients affected by apparent early-stage ovarian cancer. However, no well-designed studies comparing laparoscopic and open surgical staging are available. In the present investigation we aimed to provide a balanced long-term comparison between these 2 approaches. Retrospective study (Canadian Task Force classification II-2). Tertiary center. Data of consecutive patients affected by early-stage ovarian cancer who had laparoscopic staging were matched 1:1 with a cohort of patients undergoing open surgical staging. The matching was conducted by a propensity-score comparison. Laparoscopic and open surgical staging. Fifty patient pairs (100 patients: 50 undergoing laparoscopic staging vs 50 undergoing open surgical staging) were included. Demographic and baseline oncologic characteristics were balanced between groups (p > .2). We observed that patients undergoing laparoscopic staging experienced longer operative time (207.2 [71.6] minutes vs 180.7 [47.0] minutes; p = .04), lower blood loss (150 [52.7] mL vs 339.8 [225.9] mL; p < .001), and shorter length of hospital stay (4.0 [2.6] days vs 6.1 [1.6] days; p < .001) compared with patients undergoing open surgical staging. No conversion to open surgery occurred. Complication rate was similar between groups. No difference in survival outcomes were observed, after a mean (SD) follow-up of 49.5 (64) and 52.6 (31.7) months after laparoscopic and open surgical staging, respectively. Our findings suggest that the implementation of minimally invasive staging does not influence survival outcomes of patients affected by early-stage ovarian cancer. Laparoscopic staging improved patient outcomes, reducing length of hospital stay. Further large prospective studies are warranted. Copyright © 2016 AAGL. Published by Elsevier Inc.

Ferrero, Adriana; Minetti, Alejandra; Bras, Cristina; Zanetti, Noelia

2007-09-25

Ethanolic and hexanic extracts from fruits and leaves of Schinus molle showed ability to control several insect pests. Potential vertebrate toxicity associated with insecticidal plants requires investigation before institutional promotion. The aim of the present study was to evaluate the acute and subacute toxicity of ethanolic extracts from fruits of Schinus molle in rats. The plant extract was added to the diet at 2g/kg body weight/day during 1 day to evaluate acute toxicity and at 1g/kg body weight/day during 14 days to evaluate subacute toxicity. At the end of the exposure and after 7 days, behavioral and functional parameters in a functional observational battery and motor activity in an open field were assessed. Finally, histopathological examinations were conducted on several organs. In both exposures, an increase in the arousal level was observed in experimental groups. Also, the landing foot splay parameter increased in the experimental group after acute exposure. Only the subacute exposure produced a significant increase in the motor activity in the open field. All these changes disappeared after 7 days. None of the exposures affected the different organs evaluated. Our results suggest that ethanolic extracts from fruits and leaves of Schinus molle should be relatively safe to use as insecticide.

Comparative ontogenetic behavior and migration of kaluga, Huso dauricus, and Amur sturgeon, Acipenser schrenckii, from the Amur River

Zhuang, P.; Kynard, B.; Zhang, L.; Zhang, T.; Cao, W.

2003-01-01

We conducted laboratory experiments with kaluga, Huso dauricus, and Amur sturgeon, Acipenser schrenckii, to develop a conceptual model of early behavior. We daily observed embryos (first life phase after hatching) and larvae (period initiating exogenous feeding) to day-30 (late larvae) for preference of bright habitat and cover, swimming distance above the bottom, up- and downstream movement, and diel activity. Day-0 embryos of both species strongly preferred bright, open habitat and initiated a strong, downstream migration that lasted 4 days (3 day peak) for kaluga and 3 days (2 day peak) for Amur sturgeon. Kaluga migrants swam far above the bottom (150 cm) on only 1 day and moved day and night; Amur sturgeon migrants swam far above the bottom (median 130 cm) during 3 days and were more nocturnal than kaluga. Post-migrant embryos of both species moved day and night, but Amur sturgeon used dark, cover habitat and swam closer to the bottom than kaluga. The larva period of both species began on day 7 (cumulative temperature degree-days, 192.0 for kaluga and 171.5 for Amur sturgeon). Larvae of both species preferred open habitat. Kaluga larvae strongly preferred bright habitat, initially swam far above the bottom (median 50-105 cm), and migrated downstream at night during days 10-16 (7-day migration). Amur sturgeon larvae strongly avoided illumination, had a mixed response to white substrate, swam 20-30 cm above the bottom during most days, and during days 12-34 (most of the larva period) moved downstream mostly at night (23-day migration). The embryo-larva migration style of the two species likely shows convergence of non-related species for a common style in response to environmental selection in the Amur River. The embryo-larva migration style of Amur sturgeon is unique among Acipenser yet studied.

The objective of this study was to investigate and to compare the early and long-term results of open surgery with endovascular intervention in the treatment of extracranial carotid artery aneurysms (ECCAs). A retrospective review of patients diagnosed with ECCAs who underwent open surgical or endovascular treatment from 1997 to 2017 was performed. Clinical characteristics, aneurysm profile, and treatment outcomes were recorded. Early results (<30 days) were evaluated in terms of mortality, perioperative stroke or transient ischemic attack, and cranial nerve injury. Late results were analyzed in terms of both overall and stroke-free survival and freedom from reinterventions. A total of 48 patients with ECCAs including 34 (70.8%) true aneurysms and 14 (29.2%) pseudoaneurysms were treated. The median age was 51 years, and 19 patients (39.6%) were men; 41 patients (85.4%) had symptoms, whereas 7 (14.6%) were asymptomatic. Among 48 patients, 32 patients (66.7%) underwent open surgery; endovascular repair was performed on 16 patients (33.3%). The 30-day stroke or transient ischemic attack rate was not significantly different between the open group (6.3% [2/32]) and the endovascular group (0% [0/16]; P = .307). Cranial nerve injuries occurred in eight patients in the open group (25%) and in no patient in the endovascular group (0%; P = .029). Median length of stay was significantly longer in the open group than in the endovascular group (20 vs 14 days, respectively; P = .013). Median follow-up was 46 months (range, 0-20 years), and no aneurysm-related death occurred during this period. Overall survival rates at 5 years were 88.7% (standard error [SE], 0.08) in the open group and 91.7% (SE, 0.08) in the endovascular group (P = .319; log-rank, .992). For the same time interval, stroke-free survival rates were 85.2% (SE, 0.10) in the open group and 92.2% (SE, 0.07) in the endovascular group (P = .653; log-rank, .201). One patient (1/28 [3.6%]) in the open group and two patients (2/16 [12.5%]) in the endovascular group underwent endovascular reinterventions because of restenosis during the follow-up period. Reintervention-free survival rates were 90.9% in the open group (SE, 0.09) and 69.2% in the endovascular group (SE, 0.21; P = .082; log-rank, 3.016). In this single-institutional experience, both operative and endovascular interventions for ECCAs provided acceptable early and 5-year results. The endovascular approach had significantly less cranial nerve injury and shorter length of hospital stay. Copyright © 2017 Society for Vascular Surgery. Published by Elsevier Inc.

Several ophthalmic findings including optic disc swelling, globe flattening and choroidal folds have been observed in astronauts following long-duration space flight. The authors now report asymmetric choroidal expansion, disc swelling and optic disc morphologic changes in a 45-year-old astronaut which occurred during long-duration space flight and persisted following his space mission. Case study of ocular findings in an astronaut documented during and after a long-duration space flight of approximately 6 months. Before, during and after his spaceflight, he underwent complete eye examination, including fundus photography, ultrasound, and optical coherence tomography. We documented asymmetric choroidal expansion inflight that largely resolved by 30 days postflight, asymmetric disc swelling observed inflight that persisted for over 180 days postflight, asymmetric optic disc morphologic changes documented inflight by OCT that persisted for 630 days postflight and asymmetric globe flattening that began inflight and continued 660 days postflight. Lumbar puncture opening pressures obtained at 7 and 365 days post-mission were 22 and 16 cm H20 respectively. The persistent asymmetric findings noted above, coupled with the lumbar puncture opening pressures, suggest that prolonged microgravity exposure may have produced asymmetric pressure changes within the perioptic subarachnoid space.

The objective of this study was to obtain three-dimensional (3D) images and to perform biomechanical simulations starting from DICOM images obtained by computed tomography (CT). Open source software were used to prepare digitized 2D images of tissue sections and to create 3D reconstruction from the segmented structures. Finally, 3D images were used in open source software in order to perform biomechanic simulations. This study demonstrates the applicability and feasibility of open source software developed in our days for the 3D reconstruction and biomechanic simulation. The use of open source software may improve the efficiency of investments in imaging technologies and in CAD/CAM technologies for implants and prosthesis fabrication which need expensive specialized software.

To report on the safety and efficacy of rectus sheath blocks, 'topped-up' using bilateral rectus sheath catheters (RSCs), in patients undergoing major open urological surgery. The RSCs were inserted under ultrasound guidance into 200 patients between April 2008 and August 2011, of whom 106 patients underwent radical retropubic prostatectomy (RRP) and 94 underwent open radical cystectomy (ORC). A retrospective case-note review was undertaken. Outcomes included technical success and complication rates of the insertion and use of RSC, visual analogue pain scores, additional analgesia requirements and length of hospital stay (LOS). All RSCs were successfully placed without complication and used for a mean of 3.6 days for ORC and 2.1 days for RRP. Early removal occurred in 6.49% of patients. Low overall pain scores were reported in both groups. Patients were more likely to require a patient-controlled analgesia system in the ORC group but the overall need for additional analgesia was low in both groups, reducing significantly after the initial 24 h. In combination with an enhanced recovery programme, LOS reduced from 17.0 to 10.8 days in the ORC group and from 6.2 to 2.8 days in the RRP group. The use of RSCs appears to offer an effective and safe method of peri-operative analgesia in patients undergoing major open urological pelvic surgery. © 2013 The Authors.

Abdominal aortic surgery is a form of major vascular surgery, which traditionally involves long hospital stays and significant postoperative morbidity. Experiences with transit ileus are often encountered after the aortic surgery. Thus traditional postoperative care involves delayed oral feeding until the patients regain their normal bowel activities. This report examines the feasibility of early postoperative feeding after abdominal aortic aneurysm (AAA) open-repair. From May 2002 through May 2003, 10 consecutive patients with infrarenal AAA who underwent elective surgical open-repair by the same surgeon in our department were reviewed. All of them had been operated upon and cared for according to the early feeding postoperative care protocol, which comprised of adjuvant epidural anesthesia, postoperative patient controlled analgesia, early postoperative feeding and early rehabilitation. The postoperative recovery and length of hospital stay were reviewed and analyzed. All patients were able to sip water within 1 day postoperatively without trouble (Average; 12.4 hours postoperatively). All but one patient was put on regular diet within 3 days postoperatively (Average; 2.2 days postoperatively). The average postoperative length of stay in hospital was 5.8 days. No patient died or had major morbidity. Early postoperative feeding after open repair of abdominal aorta is safe and feasible. The postoperative recovery could be improved and the length of stay reduced by simply using adjuvant epidural anesthesia during surgery, postoperative epidural patient-controlled analgesia, early feeding, early ambulation, and early rehabilitation. The initial success of our postoperative recovery program of aortic repair was demonstrated.

The Virtual International Day of the Midwife (VIDM) (www.vidm.org) is an annual online conference designed to break down traditional barriers to continuing professional development (CPD); provide online opportunities for international midwifery networking; and model open access communication and collaboration practices. Whilst the VIDM is designed to reach midwives all around the world, issues of access to the Internet, language and cultural differences prevent some midwives from attending, especially those who live in resource-poor countries. Nevertheless, the VIDM has successfully demonstrated how CPD can be delivered to midwives in a flexible and cost-effective way, as well as bring them together in a truly global open and collaborative environment.

The impact of early repeated pain experiences on stress responsiveness and emotionality at maturity in rats.

The intensive care necessary for premature newborns is characterized by multiple procedures, many of which are painful. Given emerging evidence that such early pain during this time of high brain plasticity may affect long-term neurodevelopmental and social-emotional functioning, this study explored the impact of early repeated pain on emotionality and stress responsivity at maturity. From birth through postnatal day 7, Fischer 344 pups underwent either paw needle prick every day versus every other day or daily paw touch, or were left unperturbed. Each paw received the designated perturbation once per day. At maturity, some animals underwent emotionality testing: either a 4-day series of open field exposures or a single elevated plus-maze (EPM) exposure. The paw prick groups exhibited less open field habituation and occupied the EPM open arms more. Two weeks later, all animals were either subjected to forced swim or not. At 1h post-swim, animals underwent either blood withdrawal for plasma corticosterone (CS) levels and ex vivo natural killer cell activity (NKCA) or were injected intravenously with radiolabeled NK-sensitive syngeneic MADB106 tumor cells and assessed for lung tumor retention. Sex was a major factor in the manifestation of perturbation-related differences in the biologic outcomes. Whereas postnatal pain differentially affected baseline tumor retention between males and females, only males exhibited perturbation-related differences in swim stress-induced increases in tumor retention and CS. Finally, male-female differences were evident in CS, NKCA, and tumor responses to swim stress. These findings suggest that early pain affects neurodevelopmental function in the mature organism; however, these relationships are complicated by sex differences, the postnatal pain schedule, and the outcome measured.

Perioperative outcomes of 6042 nephrectomies in 2012: surgeon-reported results in the UK from the British Association of Urological Surgeons (BAUS) nephrectomy database.

To present the perioperative outcomes from the British Association of Urological Surgeons (BAUS) nephrectomy dataset for 2012, the first year of public reporting of individual surgeon outcomes in the UK. All nephrectomies performed in the year 2012 and recorded in the database were analysed. These were divided into simple nephrectomy (SN), partial nephrectomy (PN), radical nephrectomy (RN), and nephroureterectomy (NU). The estimated capture rate for nephrectomy was 80%. The outcomes measured were 30-day mortality (30-DM), Clavien-Dindo complications grade ≥III, blood transfusion, conversion to open, and length of stay. The overall 30-DM was 0.55% (SN 0.53%; PN 0.10%; RN 0.52%; NU 1.27%). Clavien-Dindo complications grade ≥III were recorded in 3.9% of nephrectomies (SN 4.3%; PN 5.4%; RN 3.1%; NU 4.5%). Blood transfusion was required during surgical admission for 8.4% of nephrectomies (SN 5.2%; PN 3.4%; RN 11.1%; NU 8.3%). Conversion to open was carried out in 5.5% of minimally invasive nephrectomies (SN 6.1%; PN 4.0%; RN 5.5%; NU 5.6%). Open nephrectomy patients remained in hospital for a median of 6 days (SN 7; PN 5; RN 7; NU 8 days), which was higher than the median 4-day stay (SN 3; PN 4; RN 4; NU 5 days) for minimally invasive surgery. Nephrectomy in 2012 was a safe procedure with morbidity and mortality rates comparable with or less than published series. The collection of surgeon-specific data should be iterative with further refinement of data categories, support for the collection process and independent validation of results. © 2014 The Authors.

We sought to identify risk factors for mortality and morbidity during the Norwood hospitalization in newborn infants with hypoplastic left heart syndrome and other single right ventricle anomalies enrolled in the Single Ventricle Reconstruction trial. Potential predictors for outcome included patient- and procedure-related variables and center volume and surgeon volume. Outcome variables occurring during the Norwood procedure and before hospital discharge or stage II procedure included mortality, end-organ complications, length of ventilation, and hospital length of stay. Univariate and multivariable Cox regression analyses were performed with bootstrapping to estimate reliability for mortality. Analysis included 549 subjects prospectively enrolled from 15 centers; 30-day and hospital mortality were 11.5% (63/549) and 16.0% (88/549), respectively. Independent risk factors for both 30-day and hospital mortality included lower birth weight, genetic abnormality, extracorporeal membrane oxygenation (ECMO) and open sternum on the day of the Norwood procedure. In addition, longer duration of deep hypothermic circulatory arrest was a risk factor for 30-day mortality. Shunt type at the end of the Norwood procedure was not a significant risk factor for 30-day or hospital mortality. Independent risk factors for postoperative renal failure (n = 46), sepsis (n = 93), increased length of ventilation, and hospital length of stay among survivors included genetic abnormality, lower center/surgeon volume, open sternum, and post-Norwood operations. Innate patient factors, ECMO, open sternum, and lower center/surgeon volume are important risk factors for postoperative mortality and/or morbidity during the Norwood hospitalization.

To compare the international normalised ratio (INR) value of patients evaluated using the CoaguChek XS versus conventional laboratory methods, in the period after open-heart surgery for mechanical valve replacement until a therapeutic range is achieved using vitamin K antagonists (VKA) together with low molecular weight heparin (LMWH). One hundred and five patients undergoing open-heart surgery for mechanical valve replacement were enrolled. Blood samples were collected from patients before surgery, and on the second and fifth postoperative days, simultaneously for both the point of care device and conventional laboratory techniques. Patients were administered VKA together with LMWH at therapeutic doses (enoxaparin 100 IU/kg twice daily) subcutaneously, until an effective range was achieved on approximately the fifth day after surgery. The mean INR values using the CoaguChek XS preoperatively and on the second and fifth days postoperatively were 1.20 (SD ± 0.09), 1.82 (SD ± 0.45), and 2.55 (SD ± 0.55), respectively. Corresponding results obtained using conventional laboratory techniques were 1.18 (SD ± 0.1), 1.81 (SD ± 0.43), and 2.51 (SD ± 0.58). The correlation coefficient was r = 0.77 preoperatively, r = 0.981 on postoperative day 2, and r = 0.983 on postoperative day 5. Results using the CoaguChek XS Handheld Coagulation Analyzer correlated strongly with conventional laboratory methods, in the bridging period between open-heart surgery for mechanical valve replacement and the achievement of a therapeutic range on warfarin and LMWH. © 2013 Wiley Periodicals, Inc.

2015-05-01

Laparoscopic colectomy is safe and effective in the treatment of many colorectal diseases. However, the effect of increasing use of laparoscopy on overall health care utilization and costs, especially in the long term, has not been thoroughly investigated. To evaluate the effect of laparoscopic vs open colectomy on short- and long-term health care utilization and costs. Retrospective multivariate regression analysis of national health insurance claims data was used to evaluate health care utilization and costs up to 1 year following elective colectomy. Data were obtained from the Truven Health Analytics MarketScan Commercial Claims and Encounters database. Patients aged 18 to 64 years who underwent elective laparoscopic or open colectomy from January 1, 2010, through December 31, 2010, were included. Patients with complex diagnoses that require increased non-surgery-related health care utilization, including malignant neoplasm, inflammatory bowel disease, human immunodeficiency virus, transplantation, and pregnancy, were excluded. Of 25 481 patients who underwent colectomy, 4160 were included in the study. Healthcare utilization, including office, hospital outpatient, and emergency department visits and inpatient services 90 and 365 days after the index procedure; total health care costs; and estimated days off from work owing to health care utilization. Of 25 481 patients who underwent colectomy, 4160 were included in the study (laparoscopic, 45.6%; open, 54.4%). The mean (SD) net and total payments were lower for laparoscopy ($23 064 [$14 558] and $24 196 [$14 507] vs $29 753 [$21 421] and $31 606 [$23 586]). In the first 90 days after surgery, an open approach was significantly associated with a 1.26-fold increase in health care costs (estimated, $1715; 95% CI, $338-$2853), increased use of heath care services, and more estimated days off from work (2.78 days; 95% CI, 1.93-3.59). Similar trends were found in the full postoperative year, with an estimated 1.18-fold increase (95% CI, 1.04-1.35) in health care expenditures and an increase of 1.15 times (95% CI, 1.08-1.23) the number of health care utilization days compared with laparoscopy. Laparoscopic colectomy results in a significant reduction in health care costs and utilization in the short- and long-term postoperative periods.

Trends in the supply of inpatient rehabilitation facilities services: 1996 to 2004.

Describe the supply of inpatient rehabilitation facilities (IRFs) services in 1996 and examine changes between 1996 and 2004, including the impact of the IRF prospective payment system (PPS) in 2002 on organizational trends. Retrospective pre-post design. Freestanding and subprovider (distinct-part units) IRFs. IRFs (N=1424), including 257 freestanding IRFs and 1167 IRF units reported in the Healthcare Cost Report Information System database, from years 1996 to 2004. Not applicable. Number of IRF openings, IRF closures, beds, and inpatient days. The number of IRFs grew from 1037 to 1183 between 1996 and 2001 and grew to 1235 between 2001 and 2004. The likelihood of IRF closures trended lower after PPS, and there was a significant increase in the likelihood of openings when PPS was introduced. For-profit, rural, and small IRFs were more likely to open over the entire period. There was a 12.9% increase in the number of total inpatient days, somewhat less than the 15.7% growth in IRF beds over the period. There was no impact of PPS on beds available but a significant decline in total inpatient days after PPS. Inpatient days rose under the Tax Equity and Fiscal Responsibility Act and declined after 2002. Yet the likelihood of openings and closures did not appear to respond to these changes, perhaps because they were modest compared with changes in local IRF markets. The IRF PPS did little to affect service distribution in less well-served areas, although we did find growth in rural areas. Occupancy rates in 2004 were close to rates at the start of the period (70%). This observation implies that IRFs were implementing strategies to recruit a sufficient number of patients, even though bed numbers were increasing and length of stay was declining. Consequently, policy that limits the potential of IRFs to increase patient admissions, such as the limits on admissions to IRFs of patients with conditions other than those included in the 75% rule, is likely to produce substantial decreases in total inpatient days.

Non-transectional open gastric bypass as the definitive bariatric procedure for 61 patients with BMI of 70 and higher.

2010-01-01

Technical difficulties in laparoscopic gastric bypass for severely obese patients have led to sleeve gastrectomy first and then laparoscopic gastric bypass as a second stage after significant weight loss. Rather than commit these fragile patients to two operations, we have done open gastric bypass as a definitive surgical treatment for extreme obesity. Office records of 61 patients with body mass index (BMI) of 70 and higher were reviewed. All underwent non-transectional open gastric bypass with a 150 cm Roux limb. Data included age, sex, weight, BMI, co-morbidities, operative information, length of stay (LOS), surgical morbidity, and percent excess weight loss (%XSWL). Data are in median (range). There were 21 (34%) men and 40 (66%) women: age, 37 years (19-53); pre-operative weight, 468 lb (300-650); and pre-operative BMI, 77 (70-95). Co-morbidities were diabetes mellitus, 26 (46%); hypertension, 26 (43%); sleep apnea, 61 (100%); gastroesophageal reflux disease, 20 (33%); and hypothyroid nine (15%). Incision length was 15 cm (12-20), abdominal wall fat thickness was 8 cm (5-13), operative time was 150 min (100-210), and estimated blood loss was 100 ml (25-750); post-op intensive care unit: yes 16 (26%) and no 44 (74%). LOS was 3 days for 44 patients (74%), 4 days for 11 (18%), 5 days for five (8%), and 7 days for one (1.6%). Post-operative morbidity was as follows: zero mortality, splenectomy, stoma leak, deep venous thrombosis, pulmonary embolus, GI bleeding, stomal ulcer, intestinal obstruction, fascial dehiscence, or 30-day readmission; wound infections in one (1.6%); skin wound separation in six (10%); pneumonia in one (1.6%); anemia in nine (14.8%); vitamin B(12) deficiency in six (10%); incisional hernia in 17 (28%); and gastric staple line disruption in two (3.3%). %XSWL were 51% in 1 year (28-84) and 60% in 2 years (27-97). Non-transectional open gastric bypass for patients with BMI of 70 and higher is safe and effective as a one-stage operation for severe obesity.

The Impact of System Level Factors on Treatment Timeliness: Utilizing the Toyota Production System to Implement Direct Intake Scheduling in a Semi-Rural Community Mental Health Clinic

PubMed Central

Weaver, A.; Greeno, C.G.; Goughler, D.H.; Yarzebinski, K.; Zimmerman, T.; Anderson, C.

2013-01-01

This study examined the effect of using the Toyota Production System (TPS) to change intake procedures on treatment timeliness within a semi-rural community mental health clinic. One hundred randomly selected cases opened the year before the change and one hundred randomly selected cases opened the year after the change were reviewed. An analysis of covariance (ANCOVA) demonstrated that changing intake procedures significantly decreased the number of days consumers waited for appointments (F(1,160)=4.9; p=.03) from an average of 11 days to 8 days. The pattern of difference on treatment timeliness was significantly different between adult and child programs (F(1,160)=4.2; p=.04), with children waiting an average of 4 days longer than adults for appointments. Findings suggest that small system level changes may elicit important changes and that TPS offers a valuable model to improve processes within community mental health settings. Results also indicate that different factors drive adult and children’s treatment timeliness. PMID:23576137

The open field test is commonly used to measure anxiety-related behavior and exploration in rodents. Here, we used it as a standardized novel environment in which to evaluate the behavioral response of infant titi monkeys (Callicebus cupreus), to determine the effect of presence of individual family members, and to assess how adverse early experience alters infant behavior. Infants were tested in the open field for 5 days at ages 4 and 6 months in four successive 5 min trials on each day. A transport cage, which was situated on one side of the open field, was either empty (non-social control) or contained the father, mother, or sibling. Infant locomotor, vocalization, and exploratory behavior were quantified. Results indicated that age, sex, social condition, and early experience all had significant effects on infant behavior. Specifically, infants were generally more exploratory at 6 months and male infants were more exploratory than females. Infants distinguished between social and non-social conditions but made few behavioral distinctions between the attachment figure and other individuals. Infants which had adverse early life experience demonstrated greater emotional and physical independence, suggesting that early adversity led to resiliency in the novel environment. PMID:28605039

A penetrating injury by a foreign body is comparatively common in the oral and maxillofacial region. On the other hand, injury to the temporomandibular joint (TMJ) by a foreign object is very rare. The TMJ is an anatomically narrow space surrounded by hard bony processes. An unusual case of trauma with severe trismus caused by a foreign body that impaled the TMJ is reported. A 55-year-old man presented with a 5 × 1-cm laceration to the right cheek caused by a flying object propelled during the use of a lawn mower. The edge of the foreign body had a metallic wire, which became imbedded in the wound. His jaw opening was severely limited. Computed tomography revealed that the foreign body was 3 mm in diameter and was impaled on the articular capsule. The object was successfully removed, and the wound and interior of the TMJ were irrigated. Rehabilitation of mouth opening was started on postoperative day 3. On day 9, mouth opening had improved to 35 mm, and he was discharged. After 1 year, mouth opening was 45 mm with no sign of any TMJ disorders. © 2016 John Wiley & Sons A/S.

To determine early effects on outcome from traumatic brain injury (TBI) induced by controlled cortical impact (CCI) associated with anaemia in mice. Outcome from TBI with concomitant anaemia would be worse than TBI without anaemia. CCI was induced with electromagnetic impaction in four groups of C57BL/6J mice: sham, sham+anaemia; TBI; and TBI+anaemia. Anaemia was created by withdrawal of 30% of calculated intravascular blood volume and saline replacement of equal volume. Functional outcome was assessed by beam-walking test and open field test (after pre-injury training) on post-injury days 3 and 7. After functional assessment, brains removed from sacrificed animals were pathological reviewed with haematoxylin and eosin, cresyl violet, Luxol Fast Blue, and IBA-1 immunostains. Beam-walking was similar between animals with TBI and TBI+anaemia (p = 0.9). In open field test, animals with TBI+anaemia walked less distance than TBI alone or sham animals on days 3 (p < 0.001) and 7 (p < 0.05), indicating less exploratory and locomotion behaviours. No specific pathologic differences could be identified. Anaemia associated with TBI from CCI is associated with worse outcome as measured by less distance travelled in the open field test at three days than if anaemia is not present.

Reduced lung volumes and atelectasis are common after open-heart surgery, and pronounced restrictive lung volume impairment has been found. The aim of this study was to investigate factors influencing lung volumes on the second postoperative day. Open-heart surgery patients (n = 107, 68 yrs, 80% male) performed spirometry both before surgery and on the second postoperative day. The factors influencing postoperative lung volumes and decrease in lung volumes were investigated with univariate and multivariate analyses. Associations between pain (measured by numeric rating scale) and decrease in postoperative lung volumes were calculated with Spearman rank correlation test. Lung volumes decreased by 50% and were less than 40% of the predictive values postoperatively. Patients with BMI >25 had lower postoperative inspiratory capacity (IC) (33 ± 14% pred.) than normal-weight patients (39 ± 15% pred.), (P = 0.04). More pain during mobilisation was associated with higher decreases in postoperative lung volumes (VC: r = 0.33, P = 0.001; FEV(1): r = 0.35, P ≤ 0.0001; IC: r = 0.25, P = 0.01). Patients with high BMI are a risk group for decreased postoperative lung volumes and should therefore receive extra attention during postoperative care. As pain is related to a larger decrease in postoperative lung volumes, optimal pain relief for the patients should be identified.

We studied the short- and long-term effects of a double social defeat (SD) on sleep parameters, EEG power, behaviour in the open field emergence test, corticosterone responsiveness, and acoustic startle responses. Pre-stress levels of corticosterone were assessed before all rats were surgically implanted with telemetric transmitters for sleep recording, and allowed 3weeks of recovery. Rats in the SD group (n=10) were exposed to 1hour SD on two consecutive days, while control rats (n=10) were left undisturbed. Telemetric sleep recordings were performed before SD (day -1), day 1 post SD, and once weekly for 3weeks thereafter. The open field emergence test was performed on day 9 and weekly for 2weeks thereafter. Blood samples for measures of corticosterone responsiveness were drawn after the last emergence test (day 23). Acoustic startle responses were tested on day 24 post SD. Overall, SD rats as a group were not affected by the social conflict. Effects of SD seemed, however, to vary according to the behaviours that the intruder displayed during the social confrontation with the resident. Compared to those SD rats showing quick submission (SDS, n=5), SD rats fighting the resident during one or both SD confrontations before defeat (SDF, n=5) showed more fragmented slow wave sleep, both in SWS1 and SWS2. They also showed longer latency to leave the start box and spent less time in the open field arena compared to SDS rats. In the startle test, SDF rats failed to show response decrement at the lowest sound level. Our results indicate that how animals behave during a social confrontation is more important than exposure to the SD procedure itself, and that rapid submission during a social confrontation might be more adaptive than fighting back.

A means of significantly shortening patients' length of hospital stay, improving their outcome and thereby also reducing costs is to use an enhanced recovery program (ERP) which is increasingly being used in a number of surgical sub-specialties. This paper provides a perspective on its prospective use in a wide-ranging, unselected cohort of patients undergoing open spinal surgery for degenerative lumbar and cervical spinal conditions. Selected spinal cases undergoing day surgery have been increasingly reported. A prospective, unselected, consecutive cohort of 246 cases, over an 18-month period, undergoing open, non-instrumented decompression spinal surgery and using ERP (and the concept of "bundles of care") was analyzed. Nine cases could not be included as they did not fully meet the entry criteria. No routine follow-up was arranged for the study group. The ages ranged widely, from 23-90 years (mean 57). In 187 the surgery for degenerative conditions was lumbar and in 50 cervical. The ASA (American Association of Anesthesiologists) ratings were 108=1; 107=2 and 22=3. Using the United Kingdom (UK) National Health Service (NHS) definitions of length of stay 225 (95%) could be finally classified as "ambulatory" and 12 (5%) were "short stay". A sub-cohort of 126 (53.2%) were "day cases". The follow-up was >1 year for all. There were no wound infections reported; 5 postdischarge cases (2.1%) needed to be seen in the Accident and Emergency (A&E) Department (less than 4 days postsurgery), but none needed re-admission; and there were 7 re-admissions (2.5%), between 4 and 30 days, and of these 6 required a further surgical procedure. There were no long-term instability complications reported in this cohort. ERP can be used for spinal surgery. There were identifiable and correctable medical and social factors found on analysis which could significantly increase the "day cases" number to over 90%.

The perioperative management of chronic kidney disease (CKD) patients undergoing open-heart surgery is challenging. In this study, we evaluated the effects of tolvaptan in CKD patients after open-heart surgery. Between 2010 to 2015, 731 patients underwent open-heart surgery in our hospital. We consecutively selected 71 patients with stage IIIa-IV CKD and divided them into two groups. Those who received tolvaptan postoperatively were defined as the "Tolvaptan group" (n = 25) and those who did not were defined as the "Non-tolvaptan group" (n = 46). We compared the urine volume of postoperative days (POD) 1 and 2, the number of days to return to preoperative body weight (BW), and the change in the postoperative estimated glomerular filtration rate (eGFR). In the tolvaptan group, the urine volume was significantly larger (P = .04) and the duration to preoperative BW tended to be shorter. Overall, the postoperative change in the eGFR tended to be better in the tolvaptan group (P = .008). In particular, we found a significantly better trend in CKD stage IV (P = .04) patients and in the patients, whose cardiopulmonary bypass (CPB) time was longer than 120 min (P = .03). Tolvaptan can safely be used for CKD patients undergoing open-heart surgery and can provide a feasible urine volume without leading to a deterioration of their renal function.

Background: Peripheral arterial disease (PAD) affects 3%–10% of the population before the age of 70 years and 15%–20% after that age. The aim of the study was to compare the incidence of complications and secondary interventions in patients who underwent each type of treatment. Methods: We analyzed 734 medical records of the Department of Surgery at the 4th Military Teaching Hospital in Wroclaw, In total, 394 were operated on with open surgery; an endarterectomy (59.39%), a vascular prosthesis implantation (31.01%), or both of these techniques (6.6%), and 340 patients had angioplasty with (50.59%) or without stenting (49.41%). Results: There were no statistically significant differences in the incidence of corresponding complications. The exception was the infection of the wound; significantly fewer were reported in the case of endovascular procedures (p = 0.0087). There were 12 occasions (3.53%) during endovascular surgeries when intraoperative conversion or re-operation using the open method occurred. In the case of open surgery, the mean hospital stay was 7.77 days (median: 8, mode: 8), while for endovascular management it was equal to 4.68 days (median: 4, mode: 3), p <0.0001. Conclusion: The endovascular method results in a similar re-operation rate and number of complications as open surgery. PMID:28496017

Secondhand smoke (SHS) is a defined occupational hazard. The association though between SHS exposure in semi-open air venues and tobacco specific carcinogen uptake is an area of debate. A cross sectional survey of 49 semi-open air cafes in Athens, Greece was performed during the summer of 2008, prior to the adoption of the national smoke free legislation. All venues had at least 1 entire wall open to allow for free air exchange. Indoor concentrations of particulate matter smaller than 2.5 microns (PM2.5) attributable to SHS were assessed during a work shift, while 1 non-smoking employee responsible for indoor and outdoor table service from each venue provided a post work shift urine sample for analysis of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL). Post work shift NNAL concentrations were correlated with work shift PM2.5 concentrations attributable to SHS (r = 0.376, p = 0.0076). Urinary NNAL concentrations among employees increased by 9.5%, per 10 μg/m(3) increase in PM2.5 concentrations attributable to SHS after controlling for the time of day and day of week. These results indicate that the commonly proposed practice of maintaining open sliding walls as a means of free air exchange does not lead to the elimination of employee exposure to tobacco specific carcinogens attributable to workplace SHS.

This study describes ovarian activity suppression of a 21/7-active low-dose combined oral contraceptive (COC) regimen that included only ethinyl estradiol (EE) during the traditional hormone-free interval (HFI) and two commercially available 28-day regimens, a 24/4 and a 21/7 regimen. The randomized, open-label, parallel-group descriptive study was conducted at two US sites. Healthy, reproductive-aged women (n=146) were randomized to one of three groups for three consecutive 28-day cycles, as follows: treatment 1 (n=39 completed): 21/7-active COC [21 days of 150 mcg desogestrel (DSG)/20 mcg EE, followed by 7 days of 10 mcg EE (DSG/EE+7 days EE)], treatment 2 (n=39 completed): 24 days of 3mg drospirenone (DRSP)/20 mcg EE, followed by 4 placebo (PBO)-pill days (DRSP/EE+4 days PBO) and treatment 3 (n=42 completed): 21 days of 100 mcg levonorgestrel (LNG)/20 mcg EE, followed by 7 PBO-pill days (LNG/EE+7 days PBO). The primary outcome was ovarian activity suppression assessed by transvaginal ultrasound and serum hormone concentrations and classified using the Hoogland and Skouby (H/S) method. Ovarian activity rate (H/S grade 4 or 5) was low for all three treatments: 0% [95% confidence interval (CI) 0-2.8] for DSG/EE+7 days EE, 1% (95% CI 0.2-5.2) for DRSP/EE+4days PBO and 1% (95% CI 0-3.9) for LNG/EE+7 days PBO. All three treatments showed similar suppression of serum progesterone, 17β-estradiol, follicle-stimulating hormone and luteinizing hormone levels. The 21/7-active low-dose COC regimen (DSG/EE+7 days EE) showed ovarian activity suppression that was similar to the 24/4 (DRSP/EE+4 days PBO) and 21/7 (LNG/EE+7days PBO) regimens. The 21/7-active low-dose COC regimen (DSG/EE+7 days EE) that included only EE during the traditional HFI showed suppression of ovarian follicular activity that was similar to the 24/4 (DRSP/EE+4days PBO) and the 21/7 (LNG/EE+7 days PBO) comparator regimens.

Microbial penetration of sterile packs was studied using single-wrap (two layers) muslin, double-wrap (four layers) muslin, and two-way crepe paper (single layer) to wrap 20 gauze sponges (2 by 2 inch). These packs were stored in the central sterile supply departments of two hospitals and processed for sterility at predetermined intervals. Microorganisms penetrated single-wrap muslin as early as 3 days and double-wrap muslin and single-wrap two-way crepe paper in 21 to 28 days stored in open shelves. The time required for microbial penetration was at least twice as long when closed cabinets were used. Single-wrap muslin packs stored in sealed, impervious plastic bags remained sterile for at least 9 months. All sterile materials in pervious wrappers should be handled as little as possible and then only with extreme care and caution. Closed cabinets offer more protection than open shelves, and single wrappers are not recommended. Images PMID:5119207

Between February and May 2009, 347 laboratory-confirmed cases of acute Q fever were reported in a southern municipal health service region in The Netherlands. Commercial dairy-goat farms were implicated and control measures were initially targeted there. A preliminary investigation also implicated a non-dairy sheep farm, open to the public on 'lamb-viewing days'. This study tested the association between visiting the non-dairy sheep farm and developing Q fever in residents of the region between February and May 2009. A case-control study of 146 cases and 431 address-matched controls was conducted. Multivariable logistic regression analysis confirmed the association between visiting to the sheep farm and Q fever disease (matched odds ratio 43, 95% confidence interval 9-200). Other risk factors were being a smoker, having a past medical history and being aged >40 years. Vaccination of sheep and goats on farms open to the public should help to reduce the number of future human cases.

Changes in proteins associated with senescence of the flowers of Hibiscus rosa-sinensis was studied using SDS-PAGE. Total extractable protein from petals decreased with senescence. Changes were noted in patterns of proteins from aging petals. Flower opening and senescence was associated with appearance and disappearance of several polypeptides. One new polypeptide with an apparent mw of 41 kd was first seen the day of flower opening and increased to over 9% of the total protein content of senescent petal tissue. Protein synthesis during aging was investigated by following uptake and incorporation of /sup 3/H-leucine into TCA-insoluble fraction of petal discs. Proteinmore » synthesis, as evidenced by the percent of label incorporated into the TCA-insoluble fraction, was greatest (32%) the day before flower opening. Senescent petal tissue incorporated 4% of label taken up into protein. Proteins were separated by SDS-PAGE and labelled polypeptides identified by fluorography. In presenescent petal tissue, radioactivity was distributed among several major polypeptides. In senescent tissue, much of the radioactivity was concentrated in the 41 kd polypeptide.« less

Age-Dependent Ocular Dominance Plasticity in Adult Mice

PubMed Central

Lehmann, Konrad; Löwel, Siegrid

2008-01-01

Background Short monocular deprivation (4 days) induces a shift in the ocular dominance of binocular neurons in the juvenile mouse visual cortex but is ineffective in adults. Recently, it has been shown that an ocular dominance shift can still be elicited in young adults (around 90 days of age) by longer periods of deprivation (7 days). Whether the same is true also for fully mature animals is not yet known. Methodology/Principal Findings We therefore studied the effects of different periods of monocular deprivation (4, 7, 14 days) on ocular dominance in C57Bl/6 mice of different ages (25 days, 90–100 days, 109–158 days, 208–230 days) using optical imaging of intrinsic signals. In addition, we used a virtual optomotor system to monitor visual acuity of the open eye in the same animals during deprivation. We observed that ocular dominance plasticity after 7 days of monocular deprivation was pronounced in young adult mice (90–100 days) but significantly weaker already in the next age group (109–158 days). In animals older than 208 days, ocular dominance plasticity was absent even after 14 days of monocular deprivation. Visual acuity of the open eye increased in all age groups, but this interocular plasticity also declined with age, although to a much lesser degree than the optically detected ocular dominance shift. Conclusions/Significance These data indicate that there is an age-dependence of both ocular dominance plasticity and the enhancement of vision after monocular deprivation in mice: ocular dominance plasticity in binocular visual cortex is most pronounced in young animals, reduced but present in adolescence and absent in fully mature animals older than 110 days of age. Mice are thus not basically different in ocular dominance plasticity from cats and monkeys which is an absolutely essential prerequisite for their use as valid model systems of human visual disorders.

The aim of this Phase III, multicentre, open-label, randomised study was to compare the efficacy and safety of ethinylestradiol (EE)/drospirenone (DRSP) in a new flexible extended regimen that allowed the management of intracyclic (breakthrough) bleeding (MIB) with that of EE/DRSP in a conventional 28-day regimen in women with moderate-to-severe primary dysmenorrhoea. Women (aged 18-40 years) with moderate-to-severe primary dysmenorrhoea-related pain received a flexible extended regimen with MIB (flexible(MIB); minimum 24, maximum 120 days of continuous tablet intake for a flexible number of cycles to reach a treatment duration of at least 140 days with 4-day breaks between cycles) or a conventional 28-day regimen (24 active and four placebo tablets for five cycles) of EE/DRSP. The primary outcome was the number of days with dysmenorrhoeic pain over 140 days. Secondary outcomes included other dysmenorrhoea-related pain outcomes, bleeding profile, satisfaction and safety. Overall, 223 patients received study medication. There were significantly fewer days with dysmenorrhoeic pain with the flexible(MIB) regimen than the conventional regimen (difference -4.2 days, 95% CI -6.5 to -2.0; p=0.0003), as well as considerably fewer days with at least moderate dysmenorrhoeic pain (difference -2.5 days, 95% CI -3.7 to -1.3), dysmenorrhoeic pain that interfered with daily activities (difference -2.2 days, 95% CI -4.2 to -0.1) and pelvic pain (difference -3.4 days, 95% CI -5.9 to -0.9). Adverse events were similar with both regimens. Compared with the conventional regimen, the flexible extended regimen of EE/DRSP with MIB was associated with a significantly greater reduction in days with dysmenorrhoeic pain in women with moderate-to-severe primary dysmenorrhoea. The flexible(MIB) regimen was also associated with greater improvements in dysmenorrhea according to the Clinical Global Impression rating scale and was generally well tolerated.

The implementation of air quality regulations in livestock-producing states increases the need for accurate on-farm determination of emission rates. Our objective was to determine the emission rates of NH, CH, and NO from the open-freestall and wastewater pond source areas on a commercial dairy in southern Idaho using a flush system with anaerobic digestion. Gas concentrations and wind statistics were measured and used with an inverse dispersion model to calculate emission rates. Average emissions per cow per day from the open-freestall source area were 0.08 kg NH, 0.41 kg CH, and 0.02 kg NO. Average emissions from the wastewater ponds (g m d) were 6.8 NH, 22 CH, and 0.2 NO. The combined emissions on a per cow per day basis from the open-freestall and wastewater pond areas averaged 0.20 kg NH and 0.75 kg CH. Combined NO emissions were not calculated due to limited available data. The wastewater ponds were the greatest source of total farm NH emissions (67%) in spring and summer. The emissions of CH were approximately equal from the two source areas in spring and summer. During the late fall and winter months, the open-freestall area constituted the greatest source area of NH and CH emissions. Data from this study can be used to develop trace gas emissions factors from open-freestall dairies in southern Idaho and other open-freestall production systems in similar climatic regions.

Hydrogen sulfide (H 2 S), an endogenous gaseous mediator, modulates many physiological functions in mammals but evidence of its involvement in emotional and behavioral aspects is currently scarce. We hypothesized that this gas plays a modulatory role in behavioral parameters in rats submitted to tests (for 5min) in the open field (OF) and elevated plus-maze (EPM - test and retest). Male Wistar rats (200-250g) were intraperitoneally injected with saline or Na 2 S (a H 2 S donor; 4, 8 and 12mg/kg) either once or for 8days, and submitted to the OF test or to the EPM test and retest. A third group (naïve) was not injected but exposed to the same experimental protocols. In the OF test, Na 2 S injected for 8days caused a decrease in self-cleaning (4, 8 and 12mg/kg) and freezing behaviors (8 and 12mg/kg), and a rise in the rate of line crossings in the central part of the arena (12mg/kg). In the EPM test and retest, Na 2 S at 12mg/kg for 8days caused an increase in the number of open arm entries and in the percentage of time spent on open arms. Our data are consistent with the notion that H 2 S exerts anxiolytic-like effects in rats submitted to the EPM and OF tests. Moreover, this gaseous modulator reduces aversive learning in the EPM retest. Copyright © 2017 Elsevier B.V. All rights reserved.

The aim of this study was to evaluate the efficacy of vacuum-assisted closure therapy in patients with open abdomen due to secondary peritonitis and to identify possible risk factors of fistula formation. The hospital OPS-database (time period 2005-2014) was searched to identify patients treated with an open abdomen due to secondary peritonitis, who underwent vacuum-assisted closure therapy. Medical records were retrospectively analyzed for patients' characteristics, cause of peritonitis, duration of vacuum therapy, number of relaparotomies, fascial closure rates, and risk factors of fistula formation. Forty-three patients (19 male, 24 female) with a median age of 65 years (range 24-90 years) were identified. The major cause of secondary peritonitis was anastomotic leakage after intestinal anastomosis or bowel perforation, the median APACHE II score was 11. Median duration of VAC treatment was 12 days (range 3-88 days). Twenty of 43 (47 %) patients died from septic complications. Delayed fascial closure was obtained by suturing in 20 of 43 patients (47 %). Overall 16 of 43 (37 %) patients developed enteroatmospheric fistulas. Re-explorations after starting VAC treatment and duration of VAC therapy were significantly associated with the occurrence of enteroatmospheric fistulas (p < 0.001). ROC curve analysis determined the optimal duration of VAC therapy to reduce the risk of fistula formation at 13 days. Long-term VAC treatment of patients with an open abdomen due to secondary peritonitis results in a relatively low fascial closure rate and a high risk of fistula formation.

Benefits of 3D printing techniques, biomodeling and surgical guides are well known in surgery, especially when the same surgeon who performed the surgery participated in the virtual surgical planning. Our objective was to evaluate the transfer of know how of a neutral 3D surgical modeling free open-source software protocol to surgeons with different surgical specialities. A one-day training session was organised in 3D surgical modeling applied to one mandibular reconstruction case with fibula free flap and creation of its surgical guides. Surgeon satisfaction was analysed before and after the training. Of 22 surgeons, 59% assessed the training as excellent or very good and 68% considered changing their daily surgical routine and would try to apply our open-source software protocol in their department after a single training day. The mean capacity in using the software improved from 4.13 on 10 before to 6.59 on 10 after training for OsiriX ® software, from 1.14 before to 5.05 after training for Meshlab ® , from 0.45 before to 4.91 after training for Netfabb ® and from 1.05 before and 4.41 after training for Blender ® . According to surgeons, using the software Blender ® became harder as the day went on. Despite improvement in the capacity in using software for all participants, more than a single training day is needed for the transfer of know how on 3D modeling with open-source software. Although the know-how transfer, overall satisfaction, actual learning outcomes and relevance of this training were appropriated, a longer training including different topics will be needed to improve training quality.

Increased activity improves broiler leg health, but also increases the heat production of the bird. This experiment investigated the effects of early open-field activity and ambient temperature on the growth and feed intake of two strains of broiler chickens. On the basis of the level of activity in an open-field test on day 3 after hatching, fast-growing Ross 208 and slow-growing i657 chickens were allocated on day 13 to one of the 48 groups. Each group included either six active or six passive birds from each strain and the groups were housed in floor-pens littered with wood chips and fitted with two heat lamps. Each group was fed ad libitum and subjected to one of the three temperature treatments: two (HH; 26°C), one (HC; 16°C to 26°C) or no (CC; 16°C) heat lamps turned on. Production and behavioural data were collected every 2 weeks until day 57. For both strains, early open-field activity had no significant effects on their subsequent behaviour or on any of the production parameters measured, and overall, the slow-growing strain was more active than the fast-growing strain. Ambient temperature had significant effects on production measures for i657 broilers, with CC chickens eating and weighing more, and with a less efficient feed conversion than HH chickens, with HC birds intermediate. A similar effect was found for Ross 208 only for feed intake from 27 to 41 days of age. Ross 208 chickens distributed themselves in the pen with a preference for cooler areas in the hottest ambient temperature treatments. In contrast, the behaviour of the slow-growing strain appeared to be relatively unaffected by the ambient temperature. In conclusion, fast-growing broilers use behavioural changes when trying to adapt to warm environments, whereas slow-growing broilers use metabolic changes to adapt to cooler ambient temperatures.

The prevention and treatment of Microwave-caused cardiovascular injury remains elusive. This study investigated the cardiovascular protective effects of compound Chinese medicine "Kang Fu Ling" (KFL) against high power microwave (HPM)-induced myocardial injury and the role of the mitochondrial permeability transition pore (mPTP) opening in KFL protection. Male Wistar rats (100) were divided into 5 equal groups: no treatment, radiation only, or radiation followed by treatment with KFL at 0.75, 1.5, or 3 g/kg/day. Electrocardiography was used to Electrophysiological examination. Histological and ultrastructural changes in heart tissue and isolated mitochondria were observed by light microscope and electron microscopy. mPTP opening and mitochondrial membrane potential were detected by confocal laser scanning microscopy and fluorescence analysis. Connexin-43 (Cx-43) and endothelial nitric oxide synthase (eNOS) were detected by immunohistochemistry. The expression of voltage-dependent anion channel (VDAC) was detected by western blotting. At 7 days after radiation, rats without KFL treatment showed a significantly lower heart rate (P<0.01) than untreated controls and a J point shift. Myocyte swelling and rearrangement were evident. Mitochondria exhibited rupture, and decreased fluorescence intensity, suggesting opening of mPTP and a consequent reduction in mitochondrial membrane potential. After treatment with 1.5 g/kg/day KFL for 7 d, the heart rate increased significantly (P<0.01), and the J point shift was reduced flavorfully (P<0.05) compared to untreated, irradiated rats; myocytes and mitochondria were of normal morphology. The fluorescence intensities of dye-treated mitochondria were also increased, suggesting inhibition of mPTP opening and preservation of the mitochondrial membrane potential. The microwave-induced decrease of Cx-43 and VDAC protein expression was significantly reversed. Microwave radiation can cause electrophysiological, histological and ultrastructural changes in the heart. KFL at 1.5 g/kg/day had the greatest protective effect on these cardiovascular events. mPTP plays an important role in the protective effects of KFL against microwave-radiation-induced myocardial injury.

Cardiovascular diseases have the highest death rates in human society. Coronary artery disease is among the most important of these diseases. No treatment of cardiovascular disease has as much impact on the quality of life of the patients as the heart surgery. The recovery from heart surgery is associated with symptoms of pain and psychological distress. In the early recovery period, the patients will face moderate symptoms of anxiety and depression. In this regard, various measures of nursing, as complementary therapy practices have been performed to help the patients for overcoming the physical and psychological needs. One of these methods, in recent years has been the use of complementary and alternative therapies, particularly massage therapy, after heart surgery. Thus, the aim of this study was to determine the effectiveness of massage therapy on the mood of patients after open-heart surgery in Isfahan Chamran Hospital during 2010-11. In this study 72 patients, who underwent coronary artery bypass surgery, were selected. They were randomly assigned to the two case and control groups. The patients of the case group (n = 36) received Swedish massage for 20 minutes in 4 sessions in 4 consecutive days, 3 to 6 days after the open-heart surgery. The patients in the control group received only the routine care. The mood questionnaire (POMS) which was used in this study has been completed the day before the start of the study and intervention and again after the last day of the intervention. SPSS software version 12 and descriptive and inferential statistical methods were used for data analysis. The comparison of study results showed that massage decreased the overall rating of the patients' mood after the surgery. The use of massage therapy as an effective nursing intervention can improve the patients' mood after open-heart surgery. Due to the low cost and simplicity of this method, it can perhaps be used as a complement to drug therapy and postoperative interventions used in these patients.

Conservative management versus endovascular or open surgery in the spectrum of type B aortic dissection.

2018-01-01

Type B aortic dissection is a life-threatening acute aortic condition often with acute ischemic signs or symptoms. With initial management focusing on alleviating malperfusion and pain, and avoiding propagation of dissection or rupture both systolic blood and pulse pressure should be reduced initially by an aggressive medical approach. In the setting of persistent signs of complications endovascular strategies have replaced open surgery and led to a fourfold increase in early survival and better long-term outcomes. An electronic health database search was performed on articles published between January 2006 and July 2017. Publications were included in this review if (I) the index aortic pathology was type B aortic (distal) dissection; (II) when medical management, open surgical replacement or thoracic endovascular aortic repair were among those options; (III) when at least one of all basic outcome criteria such as survival, spinal cord ischemia and cerebrovascular accident was reported; (IV) when ≥15 serial patients were included. A total of 62 studies were eligible and analysed. Our manuscript has summarized data collected over 12 years on management specific outcomes in the setting of distal aortic dissection and provides an up-to-date interpretation of the published evidence. For complicated cases, treated acutely, the 30-day or in-hospital mortality was 7.3% when managed by endovascular means, whereas the pooled rate for 30-day or in-hospital mortality was 19.0% when subjected to open repair. For acute uncomplicated type B dissection usually treated with blood pressure lowering medications, the pooled 30-day or in-hospital mortality rate was 2.4%. Survival rates at 5 years averaged at 60% (40% mortality). Freedom from any aortic event ranged from 34.0% to 83.9%, underlining an inherent risk of progression and late complications. For chronic complicated type B dissection, the rates of stroke, paraplegia and operative mortality following endovascular repair ranged from 5% to 13%, 2% to 13% and 2 to 13%, respectively, while 5-year survival rates after open repair ranged from 60% to 90%. In chronic uncomplicated type B dissection almost 90% of patients survive initial hospitalization and were subjected to medical management with a 5-year survival of 50-80%. However, up to 20-55% of medically treated patients develop aneurysmal degeneration after 5 years with an unknown risk of rupture. Currently, the less invasive strategy of endovascular repair (as compared to open surgery) provides improved 30-day or in-hospital survival in the setting of complicated acute type B aortic dissection and may seek broad application. Open surgical aortic reconstruction should be left to experienced aortic centres if endovascular management is not an option.

Improved infiltration series for studying stomatal opening as illustrated with coffee

Very satisfactory results have been obtained in estimation of the degree of stomatal opening of several plant species by using infiltration series prepared with Nujol mineral oil diluted with xylol, kerosene, n-dodecane, n-tetradecane, or Bayol-D. All of these materials, except Nujol, infiltrate the leaves when the stomata are only slightly open. Nujol does not penetrate even wide open stomata, except for plants with particularly large stomata. The results with coffee plants show that leaves exposed to direct sunlight decreased their stomatal aperture during periods of strong illumination in the middle of the day (more than about 8000 fc). 9 references,more » 2 figures.« less

Pharmacokinetic profile of extended-release versus immediate-release oral naproxen sodium after single and multiple dosing under fed and fasting conditions: two randomized, open-label trials.

PubMed

Laurora, Irene; Wang, Yuan

2016-10-01

Extended-release (ER) naproxen sodium provides pain relief for up to 24 hours with a single dose (660 mg/day). Its pharmacokinetic profile after single and multiple dosing was compared to immediate release (IR) naproxen sodium in two randomized, open-label, crossover studies, under fasting and fed conditions. Eligible healthy subjects were randomized to ER naproxen sodium 660-mg tablet once daily or IR naproxen sodium 220-mg tablet twice daily (440 mg initially, followed by 220 mg 12 hours later). Primary variables: pharmacokinetic parameters after singleday administration (day 1) and at steady state after multiple-day administration (day 6). Total exposure was comparable for both treatments under fasting and fed conditions. After fasting: peak naproxen concentrations were slightly lower with ER naproxen sodium than with IR naproxen sodium but were reached at a similar time. Fed conditions: mean peak concentrations were comparable but reached after a longer time with ER vs. IR naproxen sodium. ER naproxen sodium was well tolerated, with a similar safety profile to IR naproxen sodium. The total exposure of ER naproxen sodium (660 mg) is comparable to IR naproxen sodium (220 mg) when administered at the maximum over the counter (OTC) dose of 660-mg daily dose on a single day and over multiple days. The rate of absorption is delayed under fed conditions.

2012-02-01

Abdominal sacrocolpopexy is considered a standard of care operation for apical vaginal vault prolapse repair. Using outcomes at our center we evaluated whether the robotic approach to sacrocolpopexy is as cost-effective as the open approach. After obtaining institutional review board approval we performed cost-minimization analysis in a retrospective cohort of patients who underwent sacrocolpopexy at our institution between 2006 and 2010. Threshold values, that is model variable values at which the most cost effective approach crosses over to an alternative approach, were determined by testing model variables over realistic ranges using sensitivity analysis. Hospital billing data were also evaluated to confirm our findings. Operative time was similar for robotic and open surgery (226 vs 221 minutes) but postoperative length of stay differed significantly (1.0 vs 3.3 days, p <0.001). Base case analysis revealed an overall 10% cost savings for robot-assisted vs open sacrocolpopexy ($10,178 vs $11,307). Tornado analysis suggested that the number of institutional robotic cases done annually, length of stay and cost per hospitalization day in the postoperative period were the largest drivers of cost. Analysis of our hospital billing data showed a similar trend with robotic surgery costing 4.2% less than open surgery. A robot-assisted approach to sacrocolpopexy can be equally or less costly than an open approach. This depends on a sufficient institutional robotic case volume and a shorter postoperative stay for patients who undergo the robot-assisted procedure.

Open-to-Air Is a Viable Option for Initial Wound Care in Necrotizing Soft Tissue Infection that Allows Early Detection of Recurrence without Need for Painful Dressing Changes or Return to Operating Room.

2018-01-01

The standard treatment of necrotizing soft tissue infection (NSTI) includes extensive surgical debridement. Care of these debridements is challenging because of the size of the wound and associated pain. A potential solution is to leave the wounds open-to-air in the period after the initial debridement, allowing for regular inspection at bedside while reducing pain associated with frequent dressing changes. We evaluated the feasibility of this approach from a pain control standpoint. An audit of wound care modalities used on adult patients with NSTI admitted to a regional burn center between January 2009 and May 2014 was performed. Patients with at least one operation were included. Those opting for palliative care were excluded. Wound care was divided into four categories: open-to-air (OTA), negative-pressure wound therapy (NPWT), packing, and ointment. Wound care, pain score, pain medication use, and number of operations were collected for the first seven days after initial debridement. Pain management was assessed by pain scores. Analgesic use was measured and compared using conversion to morphine milligram equivalents (MME). Ninety-six patients were included; 67% were men with average age of 50 years, resulting in a total of 672 days of wound care evaluated: 69 days of OTA, 127 days of NPWT, 200 days of packing, and 126 days of ointment (150 days were undocumented). Average daily pain score from all wound care modalities was 2.00. Negative pressure wound therapy had the highest reported daily pain score (2.18, p = 0.034), whereas OTA had the lowest pain score (1.63, p < 0.05). Mortality was lower in the OTA cohort but was not statistically significant; there were no other differences in long-term outcome. Leaving wounds OTA is a safe and viable option in the immediate post-debridement period of NSTI to reduce pain, while permitting frequent re-evaluation for quick recognition of disease progression and repeat operative debridement if necessary.

To investigate whether the inclusion of deep breathing exercises in physiotherapy-directed early mobilisation confers any additional benefit in reducing postoperative pulmonary complications (PPCs) when patients are treated once daily after elective open upper abdominal surgery. This study also compared postoperative outcomes following early and delayed mobilisation. Cluster randomised controlled trial. Single-centre study in a teaching hospital. Eighty-six high-risk patients undergoing elective open upper abdominal surgery. Three groups: early mobilisation (Group A), early mobilisation plus breathing exercises (Group B), and delayed mobilisation (mobilised from third postoperative day) plus breathing exercises (Group C). PPCs and postoperative outcomes [number of days until discharge from physiotherapy, physiotherapy input and length of stay (LOS)]. There was no significant difference in PPCs between Groups A and B. The LOS for Group A {mean 10.7 [standard deviation (SD) 5.0] days} was significantly shorter than the LOS for Groups B [mean 16.7 (SD 9.7) days] and C [mean 15.2 (SD 9.8) days; P=0.036]. The greatest difference was between Groups A and B (mean difference -5.93, 95% confidence interval -10.22 to -1.65; P=0.008). Group C had fewer smokers (26%) and patients with chronic obstructive pulmonary disease (0%) compared with Group B (53% and 14%, respectively). This may have led to fewer PPCs in Group C, but the difference was not significant. Despite Group C having fewer PPCs and less physiotherapy input, the number of days until discharge from physiotherapy and LOS were similar to Group B. The addition of deep breathing exercises to physiotherapy-directed early mobilisation did not further reduce PPCs compared with mobility alone. PPCs can be reduced with once-daily physiotherapy if the patients are mobilised to a moderate level of exertion. Delayed mobilisation tended to increase physiotherapy input and the number of days until discharge from physiotherapy compared with early mobilisation. Crown Copyright © 2012.

To describe the sequential healing of open extraction sockets at which no attempts to obtain a primary closure of the coronal access to the alveolus have been made. The third mandibular premolar was extracted bilaterally in 12 monkeys, and no sutures were applied to close the wound. The healing after 4, 10, 20, 30, 90 and 180 days was morphometrically studied. After 4 days of healing, a blood clot mainly occupied the extraction sockets, with the presence of an inflammatory cells' infiltrate. A void was confined in the central zones of the coronal and middle regions, in continuity with the entrance of the alveoli. At 10 days, the alveolus was occupied by a provisional matrix, with new bone formation lining the socket bony walls. At 20 days, the amount of woven bone was sensibly increasing. At 30 days, the alveolar socket was mainly occupied by mineralized immature bone at different stages of healing. At 90 and 180 days, the amount of mineralized bone decreased and substituted by trabecular bone and bone marrow. Bundle bone decreased from 95.5% at 4 days to 7.6% at 180 days, of the whole length of the inner alveolar surface. Modeling processes start from the lateral and apical walls of the alveolus, leading to the closure of the socket with newly formed bone within a month from extraction. Remodeling processes will follow the previous stages, resulting in trabecular and bone marrow formation and in a corticalization of the socket access. © 2013 John Wiley & Sons A/S.

Objective The differential effect of stent design, i.e. open-cell vs. closed-cell configuration, on carotid velocities detected by duplex ultrasonography (DUS) has not been established. To identify possible stent design differences in carotid velocities, we analyzed our experience with DUS obtained before and immediately after CAS. Methods In a series of 141 CAS procedures performed over a 3 year period, data from the first postinterventional DUS and carotid angiograms were evaluated for each patient. Peak systolic velocities (PSV), end-diastolic velocities (EDV), and internal carotid artery-to-common carotid artery (ICA-CCA) PSV ratios were compared according to stent design. Differences in carotid velocities were analyzed using nonparametric statistical tests. Results Completion angiogram revealed successful revascularization and less that 30% residual stenosis in each case. The 30-day stroke-death rate in this series was 1.6% and was unrelated to stent type. Postintervention DUS was obtained a median of 5 days after CAS (interquartile range [IQR], 1–25 days). Closed-cell stents were used in 41 cases (29%) and open-cell stents in 100 cases (71%). The median PSV was significantly higher for closed-cell stents (122cm/s; IQR, 89–143cm/s) than for open-cell stents (95.9cm/s; IQR, 77.–123) (P=.007). Median EDV (36 vs. 29 cm/s; P=.006) and median ICA-CCA PSV ratio (1.6 vs. 1.1; P=.017) were also significantly higher for closed-cell stents. 45% of closed-cell stents had carotid velocities that exceeded the threshold of 50% stenosis by DUS criteria for a nonstented artery compared to 26% of open-cell stents (P=.04). In fact, closed cell-stents had a 2.2-fold increased risk of yielding abnormally elevated carotid velocities after CAS compared with open-cell stents (odds ratio, 2.2; 95% confidence interval, 1.02–4.9). Conclusions Carotid velocities are disproportionately elevated after CAS with closed-cell stents compared with open-cell stents, which suggests that velocity criteria for quantifying stenosis may require modification according to stent design. The importance of these differences in carotid velocities related to stent design and the potential relationship with recurrent stenosis remains to be established. PMID:19268763

Background: Transitioning patients between cholinesterase inhibitors was thought to require a washout period to avoid cholinergic toxicity; however, evidence suggests that abrupt discontinuation of donepezil may lead to cognitive decline. We evaluated the safety and tolerability of an immediate switch from donepezil to rivastigmine. Method: This is an analysis of the safety and tolerability data from the first 28 days of an open-label, multicenter, prospective trial, conducted from August 2002 to August 2003, in which patients satisfying NINCDS-ADRDA criteria for probable Alzheimer's disease were administered rivastigmine 1.5 mg b.i.d. within 24 to 36 hours of donepezil discontinuation. Results are compared with adverse event rates from a retrospective analysis of a pivotal, placebo-controlled trial examining patients not previously treated with a cholinesterase inhibitor. Results: Fifty-eight of 61 patients completed the first 28 days, with no suspected drug-related discontinuations during this period. Incidence of overall gastrointestinal adverse events at day 7 was 8.2%, and at day 28 was 11.5%. The corresponding rate for rivastigmine-treated patients in the retrospective analysis of the pivotal trial for day 7 was 3.3%. Conclusion: These study results suggest that transitioning patients from donepezil to rivastigmine without a washout period is safe and well tolerated. PMID:15841194

We investigated the effect of stage of pregnancy on estimates of breeding values for milk yield and milk persistency in Gyr and Holstein dairy cattle in Brazil. Test-day milk yield records were analyzed using random regression models with or without the effect of pregnancy. Models were compared using residual variances, heritabilities, rank correlations of estimated breeding values of bulls and cows, and number of nonpregnant cows in the top 200 for milk yield and milk persistency. The estimates of residual variance and heritabilities obtained with the models with or without the effect of pregnancy were similar for the two breeds. Inclusion of the effect of pregnancy in genetic evaluation models for these populations did not affect the ranking of cows and sires based on their predicted breeding values for 305-day cumulative milk yield. In contrast, when we examined persistency of milk yield, lack of adjustment for the effect of pregnancy overestimated breeding values of nonpregnant cows and cows with a long days open period and underestimated breeding values of cows with a short days open period. We recommend that models include the effect of days of pregnancy for estimation of adjustment factors for the effect of pregnancy in genetic evaluations of Dairy Gyr and Holstein cattle.

Emergency endovascular repair (EVAR) for ruptured abdominal aortic aneurysm (rAAA) may have lower operative mortality rates than open surgical repair. Concerns remain that the early survival benefit after EVAR for rAAA may be offset by late reinterventions. The aim of this study was to compare reintervention rates and cost-effectiveness of EVAR and open repair for rAAA. A retrospective analysis was undertaken of patients with rAAA undergoing EVAR or open repair over 6 years. A health economic model developed for the cost-effectiveness of elective EVAR was used in the emergency setting. Sixty-two patients (mean age 77·9 years) underwent EVAR and 85 (mean age 75·9 years) had open repair of rAAA. Median follow-up was 42 and 39 months respectively. There was no significant difference in 30-day mortality rates after EVAR and open repair (18 and 26 per cent respectively; P = 0·243). Reintervention rates were also similar (32 and 31 per cent; P = 0·701). The mean cost per patient was €26,725 for EVAR and €30,297 for open repair, and the cost per life-year gained was €7906 and €9933 respectively (P = 0·561). Open repair had greater initial costs: longer procedural times (217 versus 178·5 min; P < 0·001) and intensive care stay (5·0 versus 1·0 days; P = 0·015). Conversely, EVAR had greater reintervention (€156,939 versus €35,335; P = 0·001) and surveillance (P < 0·001) costs. There was no significant difference in reintervention rates after EVAR or open repair for rAAA. EVAR was as cost-effective at mid-term follow-up. The increased procedural costs of open repair are not outweighed by greater surveillance and reintervention costs after EVAR. © 2014 BJS Society Ltd. Published by John Wiley & Sons Ltd.

Transoral endoscopic thyroidectomy vestibular approach (TOETVA) provides excellent cosmetic results from its potential for scar-free operation. The procedure has been applied successfully for Graves' disease by the authors of this work and compared with the standard open cervical approach to evaluate its safety and outcomes. From January 2014 to November 2016, a total of 97 patients with Graves' disease were reviewed retrospectively. Open thyroidectomy (OT) and TOETVA were performed in 49 patients and 46 patients, respectively. For TOETVA, a three-port technique through the oral vestibule was utilized. The thyroidectomy was done endoscopically using conventional laparoscopic instruments and an ultrasonic device. Patient demographics and surgical variables, including operative time, blood loss, and complications, were investigated and compared. TOETVA was performed successfully in all 45 patients, although conversion to open surgery was deemed necessary in one patient. All patient characteristics for both groups were similar. Operative time was shorter for the OT group compared to the TOETVA group, which totaled 101.97±24.618 and 134.11±31.48 minutes, respectively (P<0.5). Blood loss was comparable for both groups. The visual analog scale (VAS) pain score for the TOETVA group was significantly lower than for the OT group on day 1 (2.08±1.53 vs . 4.57±1.35), day 2 (0.84±1.12 vs . 2.57±1.08) and day 3 (0.33±0.71 vs . 1.08±1.01) (P<0.05). Transient recurrent laryngeal nerve (RLN) palsy was found in four and two cases of TOETVA and OT group, respectively. Transient hypocalcemia was found in ten and seven cases of TOETVA and OT group, respectively. No other complications were observed. TOETVA is a feasible and safe treatment for Graves' disease in comparison to the standard open cervical approach. It is considered a viable alternative for patients who have been indicated for surgery with excellent cosmetic results.

Chronic mesenteric ischemia (CMI) continues to be a devastating diagnosis. There is a national trend toward increased use of endovascular procedures with improved survival for the treatment of these patients. Our aim was to evaluate whether this trend has changed CMI patients' length of hospitalization and health care cost. We identified all patients admitted for CMI from the National Inpatient Sample (NIS) from 2000 to 2014. Our primary end points included length of hospital stay (LOS) and cost of hospitalization (COH). Our secondary end points included mortality assessment of the CMI hospitalization. There were 15,475 patients admitted for CMI. The mean age of patients was 71 years, and 4022 (26.0%) were male. There were 10,920 (70.6%) patients treated endovascularly (ENDO) and 4555 (29.4%) patients treated in an open fashion (OPEN). Although a higher proportion of patients in the ENDO (43.3%) group vs OPEN (33.1%) had a Charlson Comorbidity Index score of ≥2 (P < .0001), they had a lower mortality rate (2.4% vs 8.7%; P < .0001), lower mean LOS (6.3 vs 14.0 days; P < .0001), and lower COH ($21,686 vs $42,974; P < .0001). After adjusting for clinical and hospital factors, OPEN continued to demonstrate higher mortality than ENDO (odds ratio, 7.2; 95% confidence interval, 4.9-10.6; P < .0001), longer LOS (mean, +9.7 days; P < .0001), and higher COH (mean, +$25,834; P < .0001). The rate of ENDO continues to rise nationally in the treatment of CMI patients. After adjusting for clinical and hospital factors, patients in the ENDO group tend to have lower in-hospital mortality of 2.4% and lower LOS by 10 days, and they incur a cost saving of >$25,000 compared with patients in the OPEN group. ENDO should be considered first line of therapy for patients with CMI. Copyright © 2017 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.

Abstract Pigs continue to grow in importance as a tool in neuroscience. However, behavioral tests that have been validated in the rodent model do not translate well to pigs because of their very different responses to behavioral stimuli. We refined metrics for assessing porcine open field behavior to detect a wide spectrum of clinically relevant behaviors in the piglet post-traumatic brain injury (TBI). Female neonatal piglets underwent a rapid non-impact head rotation in the sagittal plane (n=8 evaluable) or were instrumented shams (n=7 evaluable). Open field testing was conducted 1 day prior to injury (day −1) in order to establish an individual baseline for analysis, and at days +1 and +4 after injury. Animals were then killed on day +6 after injury for neuropathological assessment of axonal injury. Injured piglets were less interested in interacting with environmental stimuli and had a lower activity level than did shams. These data were compared with previously published data for axial rotational injuries in neonatal piglets. Acute behavioral outcomes post-TBI showed a dependence on the rotational plane of the brain injury, with animals with sagittal injuries demonstrating a greater level of inactivity and less random usage of the open field space than those with axial injuries. The persistence of axonal injury is also dependent on the rotational plane, with sagittal rotations causing more prolonged injuries than axial rotations. These results are consistent with animal studies, finite element models, and studies of concussions in football, which have all demonstrated differences in injury severity depending upon the direction of head impact rotation.

Alcohol dependence is a progressive chronic disorder characterized by narrowing of the drinking repertoire, salience of drinking, tolerance and withdrawal phenomenon, compulsion to drink, and frequent relapses. Baclofen has been shown to promote abstinence, to reduce craving, and to reduce anxiety in alcohol-dependent individuals, and it promises to be a useful agent, although clinical data are limited at present. The current study aimed to test the utility of baclofen, a GABA agonist, in improving the relapse rates in alcohol-dependent subjects. A total of 122 alcohol-dependent subjects were randomized into two groups. Groups were administered baclofen (30 mg/day) or benfothiamine (a nutritional supplement) using an open label design. Both groups received brief motivational intervention. Subjects were assessed at 0, 2, 4, 8, and 12 weeks for the primary outcome measures: time to first relapse, heavy drinking days, cumulative abstinence duration, and craving (measured by the Obsessive Compulsive Drinking Scale (OCDS)). Seventy-two participants received baclofen, and 50 received benfothiamine. Participants receiving baclofen remained abstinent for significantly more days than the benfothiamine group (p < 0.05). The percentage of heavy drinking days was significantly lower in the baclofen group (p = 0.001). Craving and anxiety scores (Hamilton Anxiety Rating Scale) were also significantly decreased in the baclofen group relative to the control group (p = 0.001). Time to first relapse was similar in both groups. In this open-label trial, alcohol-dependent participants receiving baclofen showed significant improvements in drinking outcomes compared with participants receiving benfothiamine. This study provides further evidence that baclofen is useful for the treatment of alcohol dependence.

Nest fates, causes of nest failure, and identities of nest predators are difficult to determine for grassland passerines. We developed a miniature video-camera system for use in grasslands and deployed it at 69 nests of 10 passerine species in North Dakota during 1996-97. Abandonment rates were higher at nests 1 day or night (22-116 hr) at 6 nests, 5 of which were depredated by ground squirrels or mice. For nests without cameras, estimated predation rates were lower for ground nests than aboveground nests (P = 0.055), but did not differ between open and covered nests (P = 0.74). Open and covered nests differed, however, when predation risk (estimated by initial-predation rate) was examined separately for day and night using camera-monitored nests; the frequency of initial predations that occurred during the day was higher for open nests than covered nests (P = 0.015). Thus, vulnerability of some nest types may depend on the relative importance of nocturnal and diurnal predators. Predation risk increased with nestling age from 0 to 8 days (P = 0.07). Up to 15% of fates assigned to camera-monitored nests were wrong when based solely on evidence that would have been available from periodic nest visits. There was no evidence of disturbance at nearly half the depredated nests, including all 5 depredated by large mammals. Overlap in types of sign left by different predator species, and variability of sign within species, suggests that evidence at nests is unreliable for identifying predators of grassland passerines.

Effect of age, impaction types and operative time on inflammatory tissue reactions following lower third molar surgery

PubMed Central

2011-01-01

Background Postoperative mobidity following third molar surgery is affected by a number of factors. The study of these factors is essential for effective planning and limitation of morbidity. The aim of this study was to determine the effect of age, type of impaction and operative time on immediate postoperative tissue reactions following mandibular third molar surgery. Methods Consecutive patients with impacted mandibular third molar teeth were studied. All the third molars were classified according to Winter's classification. Surgical extraction was performed on all the patients by a single surgeon under local anaesthesia. The operation time was determined by the time lapse between incision and completion of suturing. Postoperative pain, swelling and trismus were evaluated. Results There were 120 patients with an age range of 19-42 years. Patients in the age range of 35-42 years recorded a lower pain score (p = 0.5) on day 1. The mouth opening was much better in the lower age group on day 2 and 5 (p = 0.007 and p = 0.01 respectively). Pain, swelling and trismus increased with increasing operative time. Distoangular impaction was significantly associated with higher VAS score on day 1 and 2 (p = 0.01, 0.0, 04). Distoangular and horizontal impaction are associated with a higher degree of swelling and reduced mouth opening on postoperative review days. Vertical impaction was associated with the least degree of facial swelling and best mouth opening. Conclusions Increasing operating time and advancing age are associated with more postoperative morbidity, likewise distoangular and horizontal impaction types. PMID:21527036

Radical cystectomy is the gold-standard treatment for muscle-invasive and refractory nonmuscle-invasive bladder cancer. We describe our technique for robotic radical cystectomy (RRC) and intracorporeal urinary diversion (ICUD), that replicates open surgical principles, and present our preliminary results. Specific descriptions for preoperative planning, surgical technique, and postoperative care are provided. Demographics, perioperative and 30-day complications data were collected prospectively and retrospectively analyzed. Learning curve trends were analyzed individually for ileal conduits (IC) and neobladders (NB). SAS(®) Software Version 9.3 was used for statistical analyses with statistical significance set at P < 0.05. Between July 2010 and September 2013, RRC and lymph node dissection with ICUD were performed in 103 consecutive patients (orthotopic NB=46, IC 57). All procedures were completed robotically replicating the open surgical principles. The learning curve trends showed a significant reduction in hospital stay for both IC (11 vs. 6-day, P < 0.01) and orthotopic NB (13 vs. 7.5-day, P < 0.01) when comparing the first third of the cohort with the rest of the group. Overall median (range) operative time and estimated blood loss was 7 h (4.8-13) and 200 mL (50-1200), respectively. Within 30-day postoperatively, complications occurred in 61 (59%) patients, with the majority being low grade (n = 43), and no patient died. Median (range) nodes yield was 36 (0-106) and 4 (3.9%) specimens had positive surgical margins. Robotic radical cystectomy with totally ICUD is safe and feasible. It can be performed using the established open surgical principles with encouraging perioperative outcomes.

This study investigated the effects of two very commonly used countermeasures against driver sleepiness, opening the window and listening to music, on subjective and physiological sleepiness measures during real road driving. In total, 24 individuals participated in the study. Sixteen participants received intermittent 10-min intervals of: (i) open window (2 cm opened); and (ii) listening to music, during both day and night driving on an open motorway. Both subjective sleepiness and physiological sleepiness (blink duration) was estimated to be significantly reduced when subjects listened to music, but the effect was only minor compared with the pronounced effects of night driving and driving duration. Open window had no attenuating effect on either sleepiness measure. No significant long-term effects beyond the actual countermeasure application intervals occurred, as shown by comparison to the control group (n = 8). Thus, despite their popularity, opening the window and listening to music cannot be recommended as sole countermeasures against driver sleepiness. © 2012 European Sleep Research Society.

The contraceptive efficacy and tolerability of a new flexible extended regimen of ethinylestradiol (EE) 20 μg/drospirenone (DRSP) 3 mg to extend the menstrual cycle and enable management of intracyclic (breakthrough) bleeding (flexible(MIB)) was investigated and the bleeding pattern compared with a conventional 28-day regimen and a fixed extended 124-day regimen. This Phase III, 2-year, multicentre, open-label study randomly (4:1:1) allocated women (aged 18-35 years) to the following regimens: flexible(MIB) (24-120 days' active hormonal intake with 4-day tablet-free intervals); conventional (24 days' active hormonal intake followed by a 4-day hormone-free interval); or fixed extended (120 days' uninterrupted active hormonal intake followed by a 4-day tablet-free interval). Primary outcomes included the number of bleeding/spotting days during Year 1 (all regimens) and the number of observed unintended pregnancies over 2 years (flexible(MIB) only). Results were analysed in 1067 women (full analysis set). The mean number of bleeding/spotting days was lower with the flexible(MIB) vs the conventional regimen [41.0±29.1 (95% CI 38.8-43.3) vs 65.8±27.0 (95% CI 62.2-69.4) days, p<0.0001; treatment difference -24.8 (95% CI -29.2 to -20.3) days]. The corresponding value for the fixed extended regimen was 60.9±51.1 (95% CI 53.9-67.9) days. The Pearl Index for the flexible(MIB) regimen was 0.64 (95% CI 0.28-1.26). All regimens had comparable tolerability profiles. EE 20 μg/DRSP 3 mg administered as a flexible extended regimen with MIB is effective, well tolerated and is associated with statistically significantly fewer bleeding/spotting days and fewer withdrawal bleeding episodes vs EE/DRSP in a conventional 28-day regimen. The flexible(MIB) also provided statistically significantly fewer spotting days vs EE/DRSP in a fixed extended 124-day regimen (post hoc evaluation). The flexible(MIB) regimen allows women to extend their menstrual cycle and manage their intracyclic (breakthrough) bleeding.

With the introduction of endovascular stent graft technology, a variety of surgical options are available for patients with aortic aneurysms. We sought to evaluate early-term and mid-term outcomes of patients undergoing endovascular and open surgical repair for non-dissected aortic arch aneurysm. Overall, 200 patients underwent treatment for isolated non-dissected aortic arch aneurysm between January 2008 and February 2016: 133 patients had open surgery and 67, endovascular repair. Early-term and mid-term outcomes were compared. Seventy percent ( n  = 47) needing endovascular repair underwent fenestrated stent graft and 30% ( n  = 20) underwent the debranched technique. Patients in the open surgery group were younger (71 vs 75 years, P  < 0.001) and had a lower prevalence of ischaemic heart disease (11% vs 35%, P  < 0.001). Intensive care unit stay (1 vs 3 days, P  < 0.001), hospital stay (11 vs 17 days, P  < 0.001) and surgical time (208 vs 390 min, P  < 0.001) were lower in the endovascular repair group than in the open surgery group. There were 3 in-hospital deaths each in the open surgery and endovascular groups (2% vs 5%, respectively, P  = 0.40). Mid-term survival ( P  < 0.001) and freedom from reintervention ( P  = 0.009) were better in the open surgery than in the endovascular repair group. No aneurysm-related deaths were observed. The propensity-matched comparison ( n  = 58) demonstrated that survival was better in the open surgery group ( P  = 0.011); no significant difference was seen in the reintervention rate ( P  = 0.28). Close follow-up for re-intervention may reduce the risk for aneurysm-related deaths and provide acceptable outcomes in patients undergoing endovascular repair. © The Author 2017.

Expectancy of an open-book test decreases performance on a delayed closed-book test.

Agarwal, Pooja K; Roediger, Henry L

2011-11-01

Two experiments examined the influence of practice with, and the expectancy of, open-book tests (students viewed studied material while taking the test) versus closed-book tests (students completed the test without viewing the studied material) on delayed retention and transfer. Using GRE materials specifically designed for open-book testing, participants studied passages and then took initial open- or closed-book tests. Open-book testing led to better initial performance than closed-book testing, but on a delayed criterial (closed-book) test both types of testing produced similar retention after a two-day delay in Experiment 1. In Experiment 2 participants were informed in advance about the type of delayed criterial test to expect (open- or closed-book). Expecting an open-book test (relative to a closed-book test) decreased participants' time spent studying and their delayed test performance on closed-book comprehension and transfer tests, demonstrating that test expectancy can influence long-term learning. Expectancy of open-book tests may impair long-term retention and transfer compared to closed-book tests, despite superior initial performance on open-book tests and students' preference for open-book tests.

Sea ice decline and 21st century trans-Arctic shipping routes

NASA Astrophysics Data System (ADS)

Melia, N.; Haines, K.; Hawkins, E.

2016-09-01

The observed decline in Arctic sea ice is projected to continue, opening shorter trade routes across the Arctic Ocean, with potentially global economic implications. Here we quantify, using Coupled Model Intercomparison Project Phase 5 global climate model simulations calibrated to remove spatial biases, how projected sea ice loss might increase opportunities for Arctic transit shipping. By midcentury for standard open water vessels, the frequency of navigable periods doubles, with routes across the central Arctic becoming available. A sea ice-ship speed relationship is used to show that European routes to Asia typically become 10 days faster via the Arctic than alternatives by midcentury, and 13 days faster by late century, while North American routes become 4 days faster. Future greenhouse gas emissions have a larger impact by late century; the shipping season reaching 4-8 months in Representative Concentration Pathway (RCP)8.5 double that of RCP2.6, both with substantial interannual variability. Moderately, ice-strengthened vessels likely enable Arctic transits for 10-12 months by late century.

STS-101: Crew Activity Report / Flight Day 5

2000-01-01

The primary mission objective for STS-101 was to deliver supplies to the International Space Station, perform a space walk, and reboost the station from 230 statute miles to 250 statute miles. The commander of this mission was, James D. Haslsell. The crew was Scott J. Horowitz, the pilot, and mission specialists Mary Ellen Weber, Jeffrey N. Williams, James S. Voss, Susan J. Helms, and Yuri Vladimirovich Usachev. This videotape shows the activities of the fifth day of the mission. The day's activities started with the opening of the hatch to the space station. Helms and Usachev then opened the hatch to the station's Unity Connecting Module. The crew also placed ducting throughout the Zarya Control Module to improve air circulation and prevent problems with stale air. Helms and Usachev are shown replacing two of six batteries to be replaced in this mission in the Zarya module. The crew began moving supplies into the space station. There are several shots of the interior of the space station.

The microbiology laboratory of our university hospital aims to provide accurate and rapid microbiological results and useful information for healthcare workers involved in both the treatment of infectious diseases and infection control. For this purpose, we have been running a microbiology laboratory open 365 days a year since 2005. Before starting this laboratory, we formulated both a precise procedural manual and educational program to increase the number of microbiological technologists from 4 to 8 persons and improve their skills. Moreover, we reviewed the reporting system. As a result, we could report positive blood cultures up to 1.4 days earlier than previously possible, and significantly improved the prognosis of MRSA bacteremia patients by the early treatment of anti-MRSA antimicrobials within 48 hours after positive blood culture. In addition, the rate of MRSA/Staphylococcus aureus decreased to 35.8%. It is essential for the treatment of infectious diseases and infection control to accept only appropriate specimens and report the results rapidly and accurately.

[Water provisions for Muscovy ducks--behaviour at duck showers and modified plasson drinkers].

2009-01-01

Feather pecking and cannibalism are serious problems in keeping Moscovy ducks. Prevention of feather pecking by regularly applied beak and claw trimming are increasingly criticised by the public. The recommendation of the Council of Europe (COE) for the keeping of Muscovy ducks in farming systems calls for environmental enrichment including water for preening and bathing after December 31,2010. A total of 126 female Muscovy ducks (not beak nor claw trimmed) from commercial breeding lines were kept for 63 resp. 70 days in four compartments with 15-16 ducks each during two production cycles. Two pens where equipped either with duck showers or open water facility (modified Plasson drinker). Water provisions were made available for the ducks four hours daily at working days from their fifth week of life until slaughter. Behaviour at the water provision was registered and analysed for the number of ducks being engaged with water (944 hours recordings over 59 days from four pens analysed in five-minute-intervals (11,540 observations). Additionally 858 feather preening bouts (five a day for each compartment) were analysed for the duration of feather preening behaviour at the water provision. From the fifth to the tenth week of life the mean percentage of animals of a pen was significantly higher at the open trough (trough: 8,3% (+/-5,37); shower: 4.9% (+/-6.1), Mann-Whitney p <0,01) and feather preening took significantly longer (trough: 134.4 sec (+/-154.8); shower: 111.2 sec (+/-152.0), Mann-Whitney p <0.01) than at the showers. Bout duration and percentage of animals observed at both water provisions increased with age. Nonetheless only ten percent of the feather preening behaviour exceeded five minutes. Most animals made use of water in the first hour of the time period when water was provided. In the first weeks of water provision open water troughs were used more often and preening behaviour was longer. When given the choice, younger ducks preferred open drinkers to showers while older ducks showed a higher preference for the duck showers. In future it may be useful to elaborate whether a combination of open water troughs in the first few weeks of the fattening period followed by the provision of showers when the birds have completed their feather coverage can help to reduce the frequency of feather pecking and cannibalism.

Ruptured abdominal aortic aneurysm (AAA) is a common vascular emergency. The mortality from emergency endovascular repair may be much lower than the 40-50% reported for open surgery. To assess whether or not a strategy of endovascular repair compared with open repair reduces 30-day and mid-term mortality (including costs and cost-effectiveness) among patients with a suspected ruptured AAA. Randomised controlled trial, with computer-generated telephone randomisation of participants in a 1 : 1 ratio, using variable block size, stratified by centre and without blinding. Vascular centres in the UK ( n  = 29) and Canada ( n  = 1) between 2009 and 2013. A total of 613 eligible participants (480 men) with a ruptured aneurysm, clinically diagnosed at the trial centre. A total of 316 participants were randomised to the endovascular strategy group (immediate computerised tomography followed by endovascular repair if anatomically suitable or, if not suitable, open repair) and 297 were randomised to the open repair group (computerised tomography optional). The primary outcome measure was 30-day mortality, with 30-day reinterventions, costs and disposal as early secondary outcome measures. Later outcome measures included 1- and 3-year mortality, reinterventions, quality of life (QoL) and cost-effectiveness. The 30-day mortality was 35.4% in the endovascular strategy group and 37.4% in the open repair group [odds ratio (OR) 0.92, 95% confidence interval (CI) 0.66 to 1.28; p  = 0.62, and, after adjustment for age, sex and Hardman index, OR 0.94, 95% CI 0.67 to 1.33]. The endovascular strategy appeared to be more effective in women than in men (interaction test p  = 0.02). More discharges in the endovascular strategy group (94%) than in the open repair group (77%) were directly to home ( p  < 0.001). Average 30-day costs were similar between groups, with the mean difference in costs being -£1186 (95% CI -£2997 to £625), favouring the endovascular strategy group. After 1 year, survival and reintervention rates were similar in the two groups, QoL (at both 3 and 12 months) was higher in the endovascular strategy group and the mean cost difference was -£2329 (95% CI -£5489 to £922). At 3 years, mortality was 48% and 56% in the endovascular strategy group and open repair group, respectively (OR 0.73, 95% CI 0.53 to 1.00; p  = 0.053), with a stronger benefit for the endovascular strategy in the subgroup of 502 participants in whom repair was started for a proven rupture (OR 0.62, 95% CI 0.43 to 0.89; p  = 0.009), whereas aneurysm-related reintervention rates were non-significantly higher in this group. At 3 years, considering all participants, there was a mean difference of 0.174 quality-adjusted life-years (QALYs) (95% CI 0.002 to 0.353 QALYs) and, among the endovascular strategy group, a cost difference of -£2605 (95% CI -£5966 to £702), leading to 88% of estimates in the cost-effectiveness plane being in the quadrant showing the endovascular strategy to be 'dominant'. Because of the pragmatic design of this trial, 33 participants in the endovascular strategy group and 26 in the open repair group breached randomisation allocation. The endovascular strategy was not associated with a significant reduction in either 30-day mortality or cost but was associated with faster participant recovery. By 3 years, the endovascular strategy showed a survival and QALY gain and was highly likely to be cost-effective. Future research could include improving resuscitation for older persons with circulatory collapse, the impact of local anaesthesia and emergency consent procedures.

The purpose of this study is to assess the preclinical therapeutic efficacy of magnetic resonance imaging (MRI)-monitored focused ultrasound (FUS)-induced blood-brain barrier (BBB) disruption to enhance Temozolomide (TMZ) delivery for improving Glioblastoma Multiforme (GBM) treatment. MRI-monitored FUS with microbubbles was used to transcranially disrupt the BBB in brains of Fisher rats implanted with 9L glioma cells. FUS-BBB opening was spectrophotometrically determined by leakage of dyes into the brain, and TMZ was quantitated in cerebrospinal fluid (CSF) and plasma by LC-MS\\MS. The effects of treatment on tumor progression (by MRI), animal survival and brain tissue histology were investigated. Results demonstrated that FUS-BBB opening increased the local accumulation of dyes in brain parenchyma by 3.8-/2.1-fold in normal/tumor tissues. Compared to TMZ alone, combined FUS treatment increased the TMZ CSF/plasma ratio from 22.7% to 38.6%, reduced the 7-day tumor progression ratio from 24.03 to 5.06, and extended the median survival from 20 to 23 days. In conclusion, this study provided preclinical evidence that FUS BBB-opening increased the local concentration of TMZ to improve the control of tumor progression and animal survival, suggesting its clinical potential for improving current brain tumor treatment.

Deep winter convection and phytoplankton dynamics in the NW Mediterranean Sea under present climate and future (horizon 2030) scenarios.

PubMed

Macias, Diego; Garcia-Gorriz, Elisa; Stips, Adolf

2018-04-26

Deep water convection (DC) in winter is one of the major processes driving open-ocean primary productivity in the Northwestern Mediterranean Sea. DC is highly variable in time, depending on the specific conditions (stratification, circulation and ocean-atmosphere interactions) of each specific winter. This variability also drives the interannual oscillations of open-ocean primary productivity in this important region for many commercially-important fish species. We use a coupled model system to 1) understand to what extent DC impacts phytoplankton seasonality in the present-day and 2) to explore potential changes in future scenarios (~2030). Our model represents quite accurately the present-day characteristics of DC and its importance for open-ocean phytoplankton blooms. However, for the future scenarios the importance of deep nutrients in fertilizing the euphotic layer of the NW Mediterranean decreases. The model simulates changes in surface density and on the levels of kinetic energy that make mesoscale activity associated with horizontal currents to become a more important fertilization mechanism, inducing subsequently phenological changes in seasonal plankton cycles. Because of our focus on the open-sea, an exact quantification of the impact of those changes on the overall biological production of the NW Mediterranean cannot be made at the moment.

The open field test is commonly used to measure anxiety-related behavior and exploration in rodents. Here, we used it as a standardized novel environment in which to evaluate the behavioral response of infant titi monkeys (Callicebus cupreus), to determine the effect of presence of individual family members, and to assess how adverse early experience alters infant behavior. Infants were tested in the open field for 5 days at ages 4 and 6 months in four successive 5 min trials on each day. A transport cage, which was situated on one side of the open field, was either empty (non-social control) or contained the father, mother, or sibling. Infant locomotor, vocalization, and exploratory behavior were quantified. Results indicated that age, sex, social condition, and early experience all had significant effects on infant behavior. Specifically, infants were generally more exploratory at 6 months and male infants were more exploratory than females. Infants distinguished between social and non-social conditions but made few behavioral distinctions between the attachment figure and other individuals. Infants which had adverse early life experience demonstrated greater emotional and physical independence, suggesting that early adversity led to resiliency in the novel environment. © 2017 Wiley Periodicals, Inc.

2012-01-01

Peripherally Inserted Central Catheters (PICCs) are increasingly being used to provide short to medium-term central venous access. The current study was designed to test the hypothesis that PICC valve technology does not influence PICC occlusion rates. Intensive care unit (ICU) patients who required a PICC were randomized to one of three types of dual lumen PICC (open ended non-valved, Groshong valve, PASV valve). PICC occlusions were recorded and managed with a protocol that used urokinase. A total of 102 patients were recruited to the study. The overall risk of occlusion per catheter was 35% (95% CI 26% to 44%). The overall rate of occlusion was 76 occlusions per 1000 catheter days (95% CI 61 to 95). Presence or type of valve did not significantly influence this rate (open-ended non-valved PICC 38% of catheters, 79 occlusions per 1000 catheter days; Groshong 38% of catheters, 60 occlusions per 1000 catheter days; PASV 27% of catheters, 99 occlusions per 1000 catheter days). The dose of urokinase required to treat PICC occlusions did not significantly differ between PICC types. Valved PICCs do not appear to influence PICC occlusion rates.

Female rats which were exposed to a single low dose of gamma irradiation (6R or 15R) at the age of 8 days produce smaller litters when mature than untreated controls. The possibility that the impaired fertility resulted from altered ovarian activity as reflected by changes in plasma levels of progesterone or estardiol was investigated. Plasma levels of both steroids were determined throughout the day of proestrus. Progesterone level was also determined in 6R animals on the day of weaning. The maturity of such irradiated rats was assessed by observing the time of vaginal opening. The results indicated that the preovulatorymore » peak of progesterone was delayed in the 6R rats whereas in the 15R group its levels were significantly lower. On the other hand no differences in estradiol plasma levels were noticed between the groups. The higher level of progesterone in the 6R animals was not evident on the day of weaning and was even in both groups, but vaginal opening in the irradiated rats was significantly delayed. The elevated level of progesterone might be responsible, among other endocrine changes, for the lower fertility of neonatally irradiated mature female rats.« less

Experimental studies showed that controlled variable ventilation (CVV) yielded better pulmonary function compared to non-variable ventilation (CNV) in injured lungs. We hypothesized that CVV improves intraoperative and postoperative respiratory function in patients undergoing open abdominal surgery. Fifty patients planned for open abdominal surgery lasting >3 h were randomly assigned to receive either CVV or CNV. Mean tidal volumes and PEEP were set at 8 ml kg -1 (predicted body weight) and 5 cm H 2 O, respectively. In CVV, tidal volumes varied randomly, following a normal distribution, on a breath-by-breath basis. The primary endpoint was the forced vital capacity (FVC) on postoperative Day 1. Secondary endpoints were oxygenation, non-aerated lung volume, distribution of ventilation, and pulmonary and extrapulmonary complications until postoperative Day 5. FVC did not differ significantly between CVV and CNV on postoperative Day 1, 61.5 (standard deviation 22.1) % vs 61.9 (23.6) %, respectively; mean [95% confidence interval (CI)] difference, -0.4 (-13.2-14.0), P=0.95. Intraoperatively, CVV did not result in improved respiratory function, haemodynamics, or redistribution of ventilation compared to CNV. Postoperatively, FVC, forced expiratory volume at the first second (FEV 1 ), and FEV 1 /FVC deteriorated, while atelectasis volume and plasma levels of interleukin-6 and interleukin-8 increased, but values did not differ between groups. The incidence of postoperative pulmonary and extrapulmonary complications was comparable in CVV and CNV. In patients undergoing open abdominal surgery, CVV did not improve intraoperative and postoperative respiratory function compared with CNV. NCT 01683578.

Introduction Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease with a fatal prognosis. The diagnosis is made on the basis of high-resolution computed tomography and histological examination in selected cases. Aim To determine the risk of complications of open lung biopsy performed in patients with IPF. Material and methods We performed a retrospective analysis of 51 patients who underwent diagnostic excision of pulmonary parenchyma due to IPF in the period 1995–2014. We assessed the complication rate, length of drainage, postoperative period and 30-day mortality. We compared the results of treatment in the groups of patients operated on with thoracotomy and videothoracoscopy. Results The mean age of patients was 58 (47% female, 53% male) forced vital capacity (FVC) was 81%, forced expiratory volume in 1 s (FEV1) was 80% and body mass index (BMI) was 27 kg/m2. Thoracotomies (lateral, muscle sparing or anterior) were performed in 20 patients between 1995 and 2012 and videothoracoscopy in 31 patients operated on in the years 2009–2014. Patients in study groups did not differ considering age (p = 0.40), gender (p = 0.81), FVC (p = 0.08), FEV1 (p = 0.13) or BMI (p = 0.75). Postoperative complications occurred in 3.9% of patients (atrial arrhythmia 1.9% and recurrent pneumothorax 1.9%) with equal incidence in both study groups (p = 0.75). Median stay after thoracotomy was 4 days while after videothoracoscopy it was 3 days (p = 0.04). Conclusions Open lung biopsy performed on patients with IPF is a safe procedure. Open lung biopsy performed through thoracotomy could be as safe as through VATS, however is characterized by longer postoperative stay. PMID:29354175

Cognitive aspects of congenital learned helplessness and its reversal by the monoamine oxidase (MAO)-B inhibitor deprenyl

Schulz, D.; Schulz, D.; Mirrione, M.

2009-11-29

Cognitive processes are assumed to change with learned helplessness, an animal model of depression, but little is known about such deficits. Here we investigated the role of cognitive and related functions in selectively bred helpless (cLH, n = 10), non-helpless (cNLH, n = 12) and wild type (WT, n = 8) Sprague Dawley rats. The animals were exposed to an open field for 10 min on each of two test days. On the third day, an object exploration paradigm was carried out. The animals were later tested for helplessness. Both cLH and cNLH rats were more active than WTs onmore » the first day in the open field. Over trials, cNLH and WT rats lowered their activity less than cLH rats. This resistance-to-habituation co-varied with a resistance to develop helplessness. In cLH rats, higher 'anxiety' or less time spent in the center of the open field co-varied with severe helplessness. In WTs, a greater reactivity to novel objects and to a spatially relocated object predicted lower levels of helplessness. In cLH rats (n = 4-5 per group), chronic treatment with a high dose of the monoamineoxidase (MAO)-Binhibitordeprenyl (10 mg/kg; i.p.), an anti-Parkinson, nootropic and antidepressant drug, attenuated helplessness. Remarkably, helplessness reversal required the experience of repeated test trials, reminiscent of a learning process. Chronic deprenyl (10 mg/kg; i.p.) did not alter locomotion/exploration or 'anxiety' in the open field. In conclusion, helplessness may be related to altered mechanisms of reinforcement learning and working memory, and to abnormalities in MAO-A and/or MAO-B functioning.« less

OBJECTIVES The incidence of surgical site infection (SSI) after open vein harvesting in coronary artery bypass grafting (CABG) patients ranges in different studies between 2 and 20%. Triclosan is an antibacterial substance that reduces the growth of bacteria by inhibiting fatty acid synthesis. We hypothesized that wound closure with triclosan-coated sutures would reduce SSI after open vein harvesting. METHODS An investigator-initiated prospective randomized double-blind single-centre study was performed with 374 patients, randomized to subcutaneous and intracutaneous leg-wound closure with either triclosan-coated sutures (Vicryl Plus® and Monocryl Plus®, Ethicon, Somerville, NJ, USA) (n = 184) or identical sutures without triclosan (n = 190) from the same manufacturer. All patients were followed up after 30 days (clinical visit) and 60 days (telephone interview). Primary endpoint was SSI within 60 days after surgery according to the definition of Center for Disease Control. Predefined secondary endpoints included culture-proven and antibiotic-treated SSI. RESULTS The primary endpoint occurred in 23 patients (12.5%) with triclosan-coated sutures and in 38 patients (20.0%) in the group without triclosan (P = 0.0497, risk ratio 0.63, (95% confidence interval 0.39–1.00). Corresponding figures for culture-proven infections were 7.6 vs 12.1%, (P = 0.15), and for antibiotic-treated infections, 10.9 vs 18.4%, (P = 0.039). Staphylococcus aureus and coagulase-negative staphylococci were the most common pathogens in both groups. Insulin-treated diabetes and vein-harvesting time were associated with SSI after vein harvesting. CONCLUSIONS Leg-wound closure with triclosan-coated sutures in CABG patients reduces SSIs after open vein harvesting. (ClinicalTrials.gov number NCT01212315). PMID:23435526

Effects of daily caffeine consumption on open-field behaviours, serum corticosterone and brain antioxidant levels were investigated after six hours of total sleep-deprivation in prepubertal mice. We tested the hypothesis that daily caffeine consumption may significantly alter behaviour, stress and antioxidative response of prepubertal mice to an acute episode of total sleep-deprivation. Prepubertal Swiss mice of both sexes were assigned to two main groups of 120 each (subdivided into 6 groups of 10 each, based on sex), and administered vehicle or graded oral doses of caffeine (10, 20, 40, 80 and 120 mg/kg/day) for 14 days. On day 14, a main group was subjected to 6 h of total sleep-deprivation by 'gentle-handling'. Open-field behaviours were then assessed in both groups, after which animals were euthanized, and levels of corticosterone, superoxide dismutase and glutathione peroxidase assayed. Horizontal locomotion, rearing and grooming increased significantly, compared to control, with sleep-deprived (SD) mice showing stronger caffeine-driven responses at higher doses; and SD female mice showing sustained response to caffeine, compared to respective males. Plasma corticosterone increased with increasing doses of caffeine in both non sleep-deprived (NSD) and SD mice; although SD mice had higher corticosterone levels. Sleep-deprivation and/or higher doses of caffeine were associated with derangements in brain antioxidant levels. Repeated caffeine consumption and/or acute sleep-deprivation led to significant changes in pattern of open-field behaviour and stress/antioxidant response in mice. Responses seen in the study are probably due to modulatory effects of caffeine on the total body response to stressful stimuli.

We have previously demonstrated that treatment with ziprasidone and aripiprazole selectively inhibit the development of behavioral sensitization to cocaine in mice. We now investigate their effects on a counter-conditioning strategy in mice and the importance of the treatment environment for this phenomenon. Evaluate the context-specificity of ziprasidone and aripiprazole on conditioned locomotion to cocaine and cocaine-induced hyperlocomotion and behavioral sensitization in a counter-conditioning strategy in mice. Animals were sensitized with saline or cocaine injections in the open-field apparatus in a 15-day intermittent treatment and subsequently treated with vehicle, 5mg/kg ziprasidone or 0.1mg/kg aripiprazole paired to the open-field or the home-cage for 4 alternate days. Mice were then challenged with saline and cocaine in the open-field apparatus on subsequent days. While treatment with ziprasidone decreased spontaneous locomotion and conditioned locomotion alike, treatment with aripiprazole specifically attenuated the expression of conditioned hyperlocomotion to cocaine. Ziprasidone and aripiprazole had no effects on cocaine-induced conditioned hyperlocomotion observed during saline challenge after drug withdrawal. Treatment with either ziprasidone or aripiprazole when previously given in the cocaine-paired environment attenuated the subsequent expression of behavioral sensitization to cocaine. Animals treated with aripiprazole in the open-field, but not in the home-cage, showed a blunted response to cocaine when receiving a cocaine challenge for the first time. Both neuroleptic drugs showed a context-dependent effectiveness in attenuating long-term expression of cocaine-induced behavioral sensitization when administered in the cocaine-associated environment, with aripiprazole also showing effectiveness in blocking the expression of acute cocaine effects.

An extensive road system with rapidly increasing traffic produces diverse ecological effects that cover a large land area. Our objective was to evaluate the effect of roads with different traffic volumes on surrounding avian distributions, and its importance relative to other variables. Grassland bird data (5 years) for 84 open patches in an outer suburban/rural landscape near Boston were analyzed relative to: distance from roads with 3000-8000 to >30,000 vehicles/day; open-habitat patch size; area of quality microhabitat within a patch; adjacent land use; and distance to other open patches. Grassland bird presence and regular breeding correlated significantly with both distance from road and habitat patch size. Distance to nearest other open patch, irrespective of size, was not significant. Similarly, except for one species, adjacent land use, in this case built area, was not significant. A light traffic volume of 3000-8000 vehicles/day (local collector street here) had no significant effect on grassland bird distribution. For moderate traffic of 8000-15,000 (through street), there was no effect on bird presence although regular breeding was reduced for 400 m from a road. For heavier traffic of 15,000-30,000 (two-lane highway), both bird presence and breeding were decreased for 700 m. For a heavy traffic volume of > or =30,000 vehicles/day (multilane highway), bird presence and breeding were reduced for 1200 m from a road. The results suggest that avian studies and long-term surveys near busy roads may be strongly affected by traffic volume or changes in volume. We conclude that road ecology, especially the effects extending outward >100 m from roads with traffic, is a sine qua non for effective land-use and transportation policy.

The objective of the research work is to assess day time traffic noise level at curbside open-air microenvironment of Kolkata city, India under heterogeneous environmental conditions. Prevailing traffic noise level in terms of A-weighted equivalent noise level (Leq) at the microenvironment was in excess of 12.6 ± 2.1 dB(A) from the day time standard of 65 dB(A) for commercial area recommended by the Central Pollution Control Board (CPCB) of India. Noise Climate and Traffic Noise Index of the microenvironment were accounted for 13 ± 1.8 dB(A) and 88.8 ± 6.1 dB(A) respectively. A correlation analysis explored that prevailing traffic noise level of the microenvironment had weak negative (-0.21; p < 0.01) and very weak positive (0.19; p < 0.01) correlation with air temperature and relative humidity. A Varimax rotated principal component analysis explored that motorized traffic volume had moderate positive loading with background noise component (L90, L95, L99) and prevailing traffic noise level had very strong positive loading with peak noise component (L1, L5, L10). Background and peak noise component cumulatively explained 80.98 % of variance in the data set. Traffic noise level at curbside open-air microenvironment of Kolkata City was higher than the standard recommended by CPCB of India. It was highly annoying also. Air temperature and relative humidity had little influence and the peak noise component had the most significant influence on the prevailing traffic noise level at curbside open-air microenvironment. Therefore, traffic noise level at the microenvironment of the city can be reduced with careful honking and driving.

Cognitive processes are assumed to change with learned helplessness, an animal model of depression, but little is known about such deficits. Here we investigated the role of cognitive and related functions in selectively bred helpless (cLH, n=10), non-helpless (cNLH, n=12) and wild type (WT, n=8) Sprague Dawley rats. The animals were exposed to an open field for 10min on each of two test days. On the third day, an object exploration paradigm was carried out. The animals were later tested for helplessness. Both cLH and cNLH rats were more active than WTs on the first day in the open field. Over trials, cNLH and WT rats lowered their activity less than cLH rats. This resistance-to-habituation co-varied with a resistance to develop helplessness. In cLH rats, higher 'anxiety' or less time spent in the center of the open field co-varied with severe helplessness. In WTs, a greater reactivity to novel objects and to a spatially relocated object predicted lower levels of helplessness. In cLH rats (n=4-5 per group), chronic treatment with a high dose of the monoamine oxidase (MAO)-B inhibitor deprenyl (10mg/kg; i.p.), an anti-Parkinson, nootropic and antidepressant drug, attenuated helplessness. Remarkably, helplessness reversal required the experience of repeated test trials, reminiscent of a learning process. Chronic deprenyl (10mg/kg; i.p.) did not alter locomotion/exploration or 'anxiety' in the open field. In conclusion, helplessness may be related to altered mechanisms of reinforcement learning and working memory, and to abnormalities in MAO-A and/or MAO-B functioning. Copyright 2009 Elsevier Inc.

Differential Behavior within a Grapevine Cluster: Decreased Ethylene-Related Gene Expression Dependent on Auxin Transport Is Correlated with Low Abscission of First Developed Berries

PubMed Central

Godoy, Francisca; Delrot, Serge; Arce-Johnson, Patricio

2014-01-01

In grapevine, fruit abscission is known to occur within the first two to three weeks after flowering, but the reason why some berries in a cluster persist and others abscise is not yet understood. Ethylene sensitivity modulates abscission in several fruit species, based on a mechanism where continuous polar auxin transport across the pedicel results in a decrease in ethylene perception, which prevents abscission. In grapevine, flowering takes about four to seven days in a single cluster, thus while some flowers are developing into berries, others are just starting to open. So, in this work it was assessed whether uneven flowering accounted for differences in berry abscission dependent on polar auxin transport and ethylene-related gene expression. For this, flowers that opened in a cluster were tagged daily, which allowed to separately analyze berries, regarding their ability to persist. It was found that berries derived from flowers that opened the day that flowering started – named as “first berries” – had lower abscission rate than berries derived from flowers that opened during the following days – named as “late berries”. Use of radiolabeled auxin showed that “first berries” had higher polar auxin transport, correlated with lower ethylene content and lower ethylene-related transcript abundance than “late berries”. When “first berries” were treated with a polar auxin transport inhibitor they showed higher ethylene-related transcript abundance and were more prone to abscise than control berries. This study provides new insights on fruit abscission control. Our results indicate that polar auxin transport sustains the ability of “first berries” to persist in the cluster during grapevine abscission and also suggest that this could be associated with changes in ethylene-related gene expression.

The Hartmann's operation, although less frequently performed today, is still used when initial colonic anastomosis is too risky in the short term. However, the subsequent procedure to restore gastrointestinal continuity is associated with significant morbidity and mortality. The review of an institutional review board (IRB)-approved prospectively maintained database provided data on the Hartmann's reversal procedure performed by either laparoscopic or open technique at our institution. The data collected included: demographic data, operative approach, conversion for laparoscopic cases and perioperative morbidity and mortality. Over a 14-year period from January 1997 to August 2011, 74 Hartmann's reversal procedures were performed (laparoscopic surgery-49, open surgery-25). The average age was 55 years for the laparoscopic and 57 years for the open surgery group, respectively. Male patients represent 61% of both groups. There was no significant difference in operative time between the two groups (149 min vs 151 min; P = 0.95), and there was a tendency to lower morbidity (3/49-7.3% vs 4/25-16%; P = 0.24) in the laparoscopic surgery group. In the laparoscopic group, eight patients (16.3%) were converted to open surgery, mostly due to severe adhesions. The length of hospital stay was significantly shorter for the laparoscopic group (5 days vs 7 days; P = 0.44). The Hartmann's reversal procedure can be safely performed in the majority of the cases using a laparoscopic approach with a low morbidity rate and achieving a shorter hospital stay.

To report our experience of laparoscopic heminephroureterectomy (Hnu) in pediatric patients with duplex anomalies, in comparison to open surgery. Retrospective review of data from patients who underwent Hnu from 2005 to 2008 was performed. The patients were divided into two groups: laparoscopic (LHnu) and open surgery (OHnu). Laparoscopic surgery was performed by transperitoneal approach in majority of cases. Open surgery was performed by retroperitoneal approach in all cases. Group LHnu: nine patients (8 females, 1 male) with median age of 14 months (range 3-205). Transperitoneal approach was performed in eight patients. Mean operative time was 182 min (CI 95% 146-217). No conversion to open surgery was necessary and there were no complications. Mean hospital stay was 2.44 days (CI 95% 1.37-3.52). Group OHnu: eight patients (3 females, 5 males) underwent nine heminephrectomies at median age of 6.9 months (range 1-12). Mean operating time was 152 min (CI 95% 121-183). There were no complications and mean hospital stay was 4.38 (CI 95% 2.59-6.16) days. Statistical analysis showed no statistically significant difference (P>0.05) in operating time between groups while mean hospital stay was significant (P=0.021). The laparoscopic approach is feasible, safe, reduces hospital stay, does not increase operating time and has better cosmetic results. We believe this should be the first option for heminephrectomy.

The early postnatal period is a sensitive period in rodents as behavioural systems are developing and maturing during this time. However, little is currently known about the behavioural effects of feeding a hyper-energetic cafeteria diet (CD) during the lactational period when offspring behaviour is tested during early adolescence. To this end, 23days old offspring from dams (Wistar) fed on CD during lactation were tested in either the open-field or the elevated plus-maze for exploration and anxiety-related behaviour. On postnatal day 9, maternal behaviour and non-maternal behaviour of the dam was assessed. It was hypothesized that lactational CD feeding would reduce anxiety in the offspring. CD-fed dams had a higher energy intake, due to an overconsumption of sugars and fats. When offspring from these dams were exposed to the open field after weaning, their locomotor activity was increased. They entered the more aversive inner zone of the open-field after a shorter latency, made more entries into and spent more time in the inner zone. Anxiety-related behaviour was not affected upon exposure to the elevated plus maze, suggesting anxiolysis in the open-field only. Increased maternal licking/grooming behaviour could possibly contribute to the anxiolytic phenotype as observed in the offspring from the CD group. In conclusion, we demonstrate that lactational overfeeding impacts on the development of behaviour in the early adolescent rat. Copyright © 2016 ISDN. Published by Elsevier Ltd. All rights reserved.

Treatment of the distal tibial fractures are challenging due to the limited soft tissue, subcutaneous location and poor vascularity. In this control-matched study, it was aimed to compare the traditional open reduction and internal fixation with minimal invasive plating (MIPO). We hypothesized that superior results may be achieved with MIPO technique. 22 patients treated with traditional open reduction and internal fixation were matched with 22 patients treated with closed reduction and MIPO on the basis of age (±3), gender, and fracture pattern (AO classification). Evaluation was assed according to the wound problems, the American Orthopaedic Foot and Ankle surgery (AOFAS) scoring, radiological union, malunion, delayed union, hospitalisation time, time from injury to surgery, and operation time. There was no significant difference in the distribution of AO/OTA classification, age, gender, AOFAS score, time from injury to operation, follow-up, bone union time, delayed union, malunion and infection (p>0.05). The operation time was significantly longer in the open group than in the MIPO group: 69.59±7.21 min. for the ORIF, and 61.14±5.61 for the MIPO group (p<0.01).The hospitalisation time was significantly longer in the open group than in the MIPO group: 7.64±4.71 days for the MIPO, and 10.18±4.32 days for the ORIF group (p<0.05). MIPO technique can be beneficial for the treatment of distal tibia AO/OTA A and B type fractures with reduced hospital stay, cost-effectiveness, and infection rate.

We evaluated the incidence, risk factors and consequences of wound infection (WI) following major head and neck cancer surgery in an open non-comparative study. The study group, comprising 95 patients who underwent clean-contaminated procedures with opening of the upper aerodigestive tract for biopsy-proven squamous cell cancer, were studied over a 1-year period. Antibiotic prophylaxis was amoxicillin and clavulanic acid. More than 20 variables were prospectively recorded for each patient. The mean follow-up was 30 months. The overall WI rate was 50.5% (48/95). Most pathogens isolated from samples were gram-negative rods. In univariate analysis, we found three risk factors for WI: alcohol consumption (P = 0.07), a hypopharyngeal location (P = 0.02) and laryngectomy stoma (P = 0.01). WI were associated with postoperative fever (P = l.5 x 10(-11)), postoperative antibiotic therapy (P = 1.5 x 10(-5)) and postoperative death (P = 0.043). Patients without WI had a median postoperative hospital stay of 15 days compared with 29 days for those with WI (P < 0.001). Healing of WI was achieved after a median time of 48 days. WI delayed postoperative radiation therapy in 21 out of 33 evaluable patients. But overall survival, and local and metastatic failures were similar with and without WI. WI are associated with a heavy postoperative morbidity, but have no prognostic impact on cancer control.

Laparoscopic repair of ventral and incisional hernia has become increasingly popular as compared to open repair. The procedure has the advantages of minimal access surgery, reduction of post operative pain and the recurrence rate. A prospective study of laparoscopic incisional hernia repair was performed in our center from August 2002 to April 2004. Eighteen cases (n: 18) were performed during the study period. Fifteen cases (n: 15) had open hernia repair previously. Sixteen patients (n: 16) had successful repair of the hernia with the laparoscopic approach and two cases were converted to open repair. The mean hernia defect size was 156cm2. There was no intraoperative or immediate postoperative complication. The mean operating time was 100 +/- 34 minutes (75 - 180 minutes). The postoperative pain was graded as mild to moderate according to visual analogue score. The mean day of discharge after surgery was two days (1 - 3 days). During follow up, three patients (16.7%) developed seroma at the hernia sac which was resolved with conservative management after three weeks. One (5.6%) patient developed recurrence six months after surgery. In conclusion, laparoscopic repair of incisional hernia particularly recurrent hernia has been shown to be safe and effective in our centre. However, careful patient selection and acquiring the necessary advanced laparoscopic surgical skills coupled with the proper use of equipment are mandatory before embarking on this procedure.

Does UV disinfection compromise sutures? An evaluation of tissue response and suture retention in salmon surgically implanted with transmitters

Walker, Ricardo W.; Brown, Richard S.; Deters, Katherine A.

Ultraviolet radiation (UVR) can be used as a tool to disinfect surgery tools used for implanting transmitters into fish. However, the use of UVR could possibly degrade monofilament suture material used to close surgical incisions. This research examined the effect of UVR on monofilament sutures to determine if they were compromised and negatively influenced tag and suture retention, incision openness, or tissue reaction. Eighty juvenile Chinook salmon Oncorhynchus tshawytscha were surgically implanted with an acoustic transmitter and a passive integrated transponder. The incision was closed with a single stitch of either a suture exposed to 20 doses of UV radiationmore » (5 minute duration per dose) or a new, sterile suture. Fish were then held for 28 d and examined under a microscope at day 7, 14, 21 and 28 for incision openness, ulceration, redness, and the presence of water mold. There was no significant difference between treatments for incision openness, redness, ulceration or the presence of water mold on any examination day. On day 28 post-surgery, there were no lost sutures; however, 2 fish lost their transmitters (one from each treatment). The results of this study do not show any differences in negative influences such as tissue response, suture retention or tag retention between a new sterile suture and a suture disinfected with UVR.« less

Reviewing clinical trial site performance identifies strategies to control outcomes. Performance across 5 geographical regions (36 sites across Asia, Australia, Europe, North America and Latin America) was investigated in a study that randomised 322 HIV-infected individuals. Regional performance was compared using descriptive analysis for time to site opening, recruitment, quality of data and laboratory samples. Follow-up consisted of 10 visits (96 weeks), electronic data collection (EDC) within 7 days of a visit and serious adverse events (SAEs) reported within 24 hours of site awareness. Median days to site opening was 250 (188 to 266), ranging from 177 (158 to 200) (Australia) to 265 (205 to 270) (Europe). Median days to ethics and regulatory approval was 182 (120 to 241) and 218 (182 to 341) days, respectively. Within regions, time to approval ranged from 187 (91 to 205) days (Australia) to 276 (175 to 384) days (Europe). Time to first randomisation ranged from 282 (250 to 313) days (Australia) to 426 (420 to 433) days (North America). Recruitment was lower than forecasted in Asia, Australia, Europe and North America at 89%, 77%, 91% and 43%, respectively. The converse was true in Latin America where despite ethics, regulatory and contractual delays, recruitment was 104% of predicted. Median days to EDC was 7 (3 to 16), ranging from 3 (1 to 16) (Asia) to 13 (8 to 14) days (North America). Median days for initial SAE submission to sponsor was 6 (2 to 20), ranging from 4 (2 to 18) (Latin America) to 24 (5 to 46) days (Australia). Sites took longer to submit final reports, overall median of 28 (7 to 91) days, ranging from 7 days (Australia) to 67 (23 to 103) days (Europe). Population availability and time to ethics and regulatory approvals influence recruitment; therefore accurate feasibility assessments are critical to site selection. Time to ethics and regulatory approval may not limit site inclusion if compensated by rapid recruitment. Identifying potential delays and methods for reduction can decrease time and costs for sponsors. Clinical Trials.Gov identifier: NCT00335322. Date of registration: 8 June 2006.

OBJECTIVE Lumbar spondylolisthesis is a degenerative condition that can be surgically treated with either open or minimally invasive decompression and instrumented fusion. Minimally invasive surgery (MIS) approaches may shorten recovery, reduce blood loss, and minimize soft-tissue damage with resultant reduced postoperative pain and disability. METHODS The authors queried the national, multicenter Quality Outcomes Database (QOD) registry for patients undergoing posterior lumbar fusion between July 2014 and December 2015 for Grade I degenerative spondylolisthesis. The authors recorded baseline and 12-month patient-reported outcomes (PROs), including Oswestry Disability Index (ODI), EQ-5D, numeric rating scale (NRS)-back pain (NRS-BP), NRS-leg pain (NRS-LP), and satisfaction (North American Spine Society satisfaction questionnaire). Multivariable regression models were fitted for hospital length of stay (LOS), 12-month PROs, and 90-day return to work, after adjusting for an array of preoperative and surgical variables. RESULTS A total of 345 patients (open surgery, n = 254; MIS, n = 91) from 11 participating sites were identified in the QOD. The follow-up rate at 12 months was 84% (83.5% [open surgery]; 85% [MIS]). Overall, baseline patient demographics, comorbidities, and clinical characteristics were similarly distributed between the cohorts. Two hundred fifty seven patients underwent 1-level fusion (open surgery, n = 181; MIS, n = 76), and 88 patients underwent 2-level fusion (open surgery, n = 73; MIS, n = 15). Patients in both groups reported significant improvement in all primary outcomes (all p < 0.001). MIS was associated with a significantly lower mean intraoperative estimated blood loss and slightly longer operative times in both 1- and 2-level fusion subgroups. Although the LOS was shorter for MIS 1-level cases, this was not significantly different. No difference was detected with regard to the 12-month PROs between the 1-level MIS versus the 1-level open surgical groups. However, change in functional outcome scores for patients undergoing 2-level fusion was notably larger in the MIS cohort for ODI (-27 vs -16, p = 0.1), EQ-5D (0.27 vs 0.15, p = 0.08), and NRS-BP (-3.5 vs -2.7, p = 0.41); statistical significance was shown only for changes in NRS-LP scores (-4.9 vs -2.8, p = 0.02). On risk-adjusted analysis for 1-level fusion, open versus minimally invasive approach was not significant for 12-month PROs, LOS, and 90-day return to work. CONCLUSIONS Significant improvement was found in terms of all functional outcomes in patients undergoing open or MIS fusion for lumbar spondylolisthesis. No difference was detected between the 2 techniques for 1-level fusion in terms of patient-reported outcomes, LOS, and 90-day return to work. However, patients undergoing 2-level MIS fusion reported significantly better improvement in NRS-LP at 12 months than patients undergoing 2-level open surgery. Longer follow-up is needed to provide further insight into the comparative effectiveness of the 2 procedures.

Objective This exploratory trial was performed to determine whether Daikenchuto accelerates recovery of gastrointestinal function in patients undergoing open colectomy for colon cancer. Methods A total of 386 patients undergoing colectomy at 1 of the 51 clinical trial sites in Japan from January 2009 to June 2011 were registered for the study (JFMC39-0902). Patients received either placebo or Daikenchuto (15.0 g/day, t.i.d) between post-operative day 2 and post-operative day 8. Primary end-points included time to first bowel movement, frequency of bowel movement and stool form. The incidence of intestinal obstruction was evaluated post-operatively. The safety profile of Daikenchuto until post-operative day 8 was also evaluated. Results The results for 336 patients (Daikenchuto, n = 174; placebo, n = 162) were available for statistical analysis. The time to first bowel movement did not differ significantly between the two groups. All patients reported having diarrhea or soft stools immediately after surgery, and the time until stool normalization (50th percentile) in the Daikenchuto and placebo groups was 6 days and 7 days, respectively. The placebo group had a significantly greater number of hard stools at post-operative day 8 (P = 0.016), and bowel movement frequency continued to increase until post-operative day 8 as well. In contrast, bowel movement frequency in the Daikenchuto group increased until post-operative day 6, however decreased from post-operative day 7 and was significantly lower at post-operative day 8 compared with the placebo group (P = 0.024). Conclusion The moderate effects of Daikenchuto were observed ∼1 week after the operation. Although Daikenchuto had an effect on gastrointestinal function after open surgery in patients with colon cancer, this study did not show its clinical benefits adequately. PMID:25972515

The retinal dysfunction and the delayed visual cortex responses shown by patients affected by glaucoma can be objectively assessed by Pattern Electroretinogram (PERG) and Visual Evoked Potentials (VEP) recordings. The present study aims to evaluate the effects of nicergoline on the retinal function and on the visual cortical responses in glaucoma patients. Sixty patients (mean age 44.6+/-3.7) with open angle glaucoma were enrolled. The patients were divided into two groups: NG Group, where 30 patients were treated with nicergoline (Cebran((R)), 2 cps day) for 30 days; and CG Group, where 30 patients were not treated. Simultaneous recordings of PERG and VEP were performed in NG patients at the baseline, at 30 days after treatment with nicergoline (day 30), and at 45 days from the end of the treatment (day 75). PERG and VEP were recorded in CG patients at the baseline and after 30 and 75 days. The visual stimulus for recording PERGs and VEPs was a checkerboard whose elements subtended a visual arc of 60' and 15' with a 70% contrast, and alternated at a frequency of 2 Hz. At the baseline none of the electrophysiological parameters observed in NG Group patients differed (P>0.05) from those of CG Group patients. At days 30 and 75, in CG Group patients the values of the PERG and VEP parameters were unmodified (P>0.05) with respect to the baseline. In NG Group patients, the 30-day treatment period with nicergoline induced a significant (P<0.01) improvement of the PERG and VEP parameters. At day 75 all the electrophysiological parameters of NG Group did not differ significantly (P>0.05) from those at the baseline. Treatment with nicergoline induces an improvement of the retinal function and of the visual cortical responses in patients affected by glaucoma. This effect disappears within 45 days after the suspension of the treatment. Copyright 1999 Academic Press.

High-risk drinking on game day represents a unique public health challenge. The authors examined the drinking behavior of college football fans and assessed the support for related interventions. The authors randomly selected 762 football fans, including college students, alumni, and other college football fans, to complete an anonymous online game-day survey. The authors collected data on participants' drinking behaviors and support for specific game-day interventions. Analysis revealed that, overall, fans drank significantly more on game day than they did the last time they partied or socialized. Nondrinkers were the most supportive of game-day interventions, followed by moderate drinkers, whereas heavy drinkers offered the least support. With the exception of limiting tailgating hours on game day, fans support game-day interventions, including alcohol-free alternatives, designating tailgating areas where open containers are permitted, and increasing law enforcement efforts.

Background Despite numerous trials assessing optimal antibiotic prophylaxis strategies for colorectal surgery, few studies have assessed real-world practice on a national scale with respect to risk of surgical site infections. Objective Using a large, national claims database we aimed to describe 1) current use of prophylactic antibiotics (type and duration) and 2) associations with surgical site infection after open colectomies. Design Retrospective study using the Premier Perspective database. Setting Patient hospitalizations nationwide from January 2006 to December 2013. Patients 90,725 patients that underwent an open colectomy in 445 different hospitals. Main Outcome Measures Multilevel multivariable logistic regressions measured associations between surgical site infection and 1) type of antibiotic used and 2) duration (day of surgery only, day of surgery and the day after, >1 day after surgery). Results Overall surgical site infection prevalence was 5.2% (n=4,750). Most patients (41.8%) received cefoxitin for prophylaxis; other choices were ertapenem (18.2%), cefotetan (10.3%), metronidazole+cefazolin (9.9%), ampicillin+sulbactam (7.6%), while 12.2% received other antibiotics. Distribution of prophylaxis duration was: 51.6%, 28.5%, and 19.9% for days 0, 0+1, and 1+, respectively. Compared to cefoxitin, lower odds for surgical site infection were observed for ampicillin+sulbactam (odds ratio 0.71; 95% confidence interval 0.63–0.82), ertapenem (odds ratio 0.65; 95% confidence interval 0.58–0.71) and metronidazole+cefazolin (odds ratio 0.56; 95% confidence interval 0.49–0.64), and “other” (odds ratio 0.81; 95% confidence interval 0.73–0.90); duration was not significantly associated with altered odds for surgical site infection. Sensitivity analyses supported the main findings. Limitations Lack of detailed clinical information in the billing dataset used. Conclusions In this national study assessing real-world use of prophylactic antibiotics in open colectomies, type of antibiotic used appeared to be associated with up to 44% decreased odds for surgical site infections. While there are numerous trials on optimal prophylactic strategies, studies that particularly focus on factors that influence the choice of prophylactic antibiotic might provide insights into ways of reducing the burden of surgical site infections in colorectal surgeries.

We have recently shown that repeated high dose injections of corticosterone (CORT) reliably increase depression-like behavior on a modified one-day version of the forced swim test. The main purpose of this experiment was to compare the effect of these CORT injections on our one-day version of the forced swim test and the more traditional two-day version of the test. A second purpose was to determine whether altered behavior in the forced swim test could be due to nonspecific changes in locomotor activity or muscle strength. Separate groups of rats received a high dose CORT injection (40 mg/kg) or a vehicle injection once per day for 21 consecutive days. Then, half the rats from each group were exposed to the traditional two-day forced swim test and the other half were exposed to our one-day forced swim test. After the forced swim testing, all the rats were tested in an open field and in a wire suspension grip strength test. The CORT injections significantly increased the time spent immobile and decreased the time spent swimming in both versions of the forced swim test. However, they had no significant effect on activity in the open field or grip strength in the wire suspension test. These results show that repeated CORT injections increase depression-like behavior regardless of the specific parameters of forced swim testing, and that these effects are independent of changes in locomotor activity or muscle strength.

Experiments were performed to determine the effect of chronic low-dose pyridostigmine bromide (PB) treatment on blood acetylcholinesterase (AChE), cardiovascular (CV) function, and behavior in C57BL/6J male mice. Chronic carotid arterial catheters were used for long-term CV measurements and for collection of blood samples. Separate groups of mice were used for behavioral open field tests. PB was administered subcutaneously using osmotic minipumps at 1 and 3 mg/kg/day for 7 days. Blood pressure and heart rate (HR) were measured continuously for 24 h before treatment and on Days 3 and 7 after minipump insertion. Blood samples were collected on the same days. Mean arterial pressure (MAP) of the control group was 108+/-2 and 104+/-2 mm Hg during the dark and light periods, respectively. HR was 510+/-18 and 493+/-19 beats/min during the dark and light periods, respectively. PB treatment had no effect on MAP or HR in either dark or light period. Basal AChE activity was 0.42+/-0.1 micromol/min/ml, with no changes observed with PB at 1 mg/kg/day. The higher PB dose (3 mg/kg/day) decreased blood AChE activity by 85% on Day 7. Despite the reduction in blood AChE activity, there were no alterations in open field behaviors (locomotor activity, rearing, distance traveled, rest time, number of entries, and pokes). In conclusion, chronic low-dose PB exposure decreased blood AChE activity but had no effect on CV function or behavior in mice.

Antidepressants (ADs) are slow to produce their therapeutic effect. This long latency promotes the development of new strategies to short their onset of action. Previous reports indicated that 17beta-estradiol (E(2)) promotes the antidepressant-like activity of fluoxetine (FLX) and desipramine (DMI) in the forced swimming test (FST). The aim of the present work was to analyze if E(2) reduces the antidepressant-like onset of action of venlafaxine (VLX), FLX, and DMI. Independent groups of ovariectomized female Wistar rats were tested in the FST and in the open field after chronic (1 to 14 days) treatment with VLX (20 mg/kg/day), FLX (1.25 mg/kg/day), or DMI (1.25 mg/kg/day) alone or in combination with a single injection of E(2) (2.5 microg/rat sc, 8 h before FST). VLX, FLX, or DMI by themselves at these doses did not induce changes in the FST at short intervals after their injection (from 1 to 7 days). The addition of E(2) promoted the antidepressant-like effect of VLX and DMI as early as day 1. Such action was also evident after 3, for FLX, and 14 days for both FLX and DMI, but not for VLX. The behavioral actions of these ADs combined with E(2) were not accompanied by increases in general activity in the open-field test. E(2) clearly reduced the latency to the onset of action for these ADs in the FST. These results represent an interesting therapeutic strategy for the treatment of depression in perimenopausal women.

Comparing hospital outcomes between open and closed tibia fractures treated with intramedullary fixation.

Tibial shaft fractures comprise a large portion of operatively treated long bone fractures, and present with the highest rate of open injuries. Intramedullary fixation has become the standard of care for both open and closed injuries. The rates of short term complications and hospital length of stay for open and closed fractures treated with intramedullary fixation is not fully known. Previous series on tibia fractures were performed at high volume centers, and data were not generalizable, further they did not report on length of stay and the impact of preoperative variables on infections, complications and reoperation. We used a large surgical database to compare these outcomes while adjusting for preoperative risk factors. Data were extracted from the ACS-NSQIP database from 2005 to 2014. Cases were identified based on CPT codes for intramedullary fixation and categorized as closed vs open based on ICD9 code. In addition to demographic and case data, primary analysis examined correlation between open and closed fracture status with infection, complications, reoperation and hospital length of stay. Secondary analysis examined preoperative variables including gender, race, age, BMI, and diabetes effect on outcomes. There were 272 cases identified. There were no significant demographic differences between open and closed tibia fracture cases. Open fracture status did not increase the rate of infection, 30day complications, reoperation, or length of stay. The only preoperative factor that correlated with length of stay was age. There was no correlation between BMI, presence of insulin dependent and nondependent diabetes, and any outcome measure. When considering the complication rates for open and closed tibial shaft fractures treated with intramedullary fixation, there is no difference between 30-day complication rate, length of stay, or return to the operating room. Our reported postoperative infection rates were comparable to previous series, adding validity to our results. The heterogeneity of the hospitals included in ACS-NSQIP database allow our data to be generalizable. These methods may underrepresent the true occurrence of infection as operatively treated tibia infections may present late, requiring late revision. Despite limitations, the data reflect on the current burden of managing these once devastating injuries. Copyright © 2017 Elsevier Ltd. All rights reserved.

To describe our experience with the implementation and refinement of an enhanced recovery programme (ERP) for radical cystectomy (RC) and urinary diversion. To assess the impact on length of stay (LOS), complication and readmission rates. In all, 165 consecutive patients undergoing open RC (ORC) and urinary diversion between January 2008 and April 2013 were entered into an ERP. A retrospective case note review was undertaken. Outcomes recorded included LOS, time to mobilisation, complication rates within the first 30 days (Clavien-Dindo classification) and readmissions. All patients were successfully entered into the ERP. As enhanced recovery principles became embedded in the unit, LOS reduced from a mean of 14 days over the initial year of the ERP to a mean of 9.2 days. The complication rate was 6.6% for Clavien ≥3, and 43.5% for Clavien ≤2. The 30-day mortality rate was 1.2%. The 30-day readmission rate was 13.9%. In the most contemporary subset of 52 patients: the median time after ORC to sit out of bed, mobilise and open bowels was day 1, 2 and 6, respectively. The ERP described for patients undergoing ORC appears to be safe. Benefits include early feeding, mobilisation and hospital discharge. The ERP will continue to develop with the incorporation of advancing evidence and technology, in particular the introduction of robot-assisted RC. © 2013 The Authors.

Endovascular abdominal aortic aneurysm repair is more profitable than open repair based on contribution margin per day.

PubMed

Rosenberg, Barry L; Comstock, Matthew C; Butz, David A; Taheri, Paul A; Williams, David M; Upchurch, Gilbert R

2005-03-01

Earlier studies have reported that endovascular abdominal aortic aneurysm (EAAA) repair yields lower total profit margins than open AAA (OAAA) repair. This study compared EAAA versus OAAA based on contribution margin per day, which may better measure profitability of new clinical technologies. Contribution margin equals revenue less variable direct costs (VDCs). VDCs capture incremental resources tied directly to individual patients' activity (eg, invoice price of endograft device, nursing labor). Overhead costs factor into total margin, but not contribution margin. The University of Michigan Health System's cost accounting system was used to extract fiscal year 2002-2003 information on revenue, total margin, contribution margin, and duration of stay for Medicare patients with principal diagnosis of AAA (ICD-9 code 441.4). OAAA had revenues of $37,137 per case versus $28,960 for EAAA, similar VDCs per case, and thus higher contribution margin per case ($24,404 for OAAA vs $13,911 for EAAA, P < .001). However, OAAA had significantly longer mean duration of stay per case (10.2 days vs 2.2 days, P < .001). Therefore, mean contribution margin per day was $2948 for OAAA, but $8569 for EAAA ( P < .001). On the basis of contribution margin per day, EAAA repair dominates OAAA repair. The shorter duration of stay with EAAA allows higher throughput, fuller overhead amortization, better use of scarce inpatient beds, and higher health system profits. Surgeons must understand overhead allocation to devices, especially when new technologies cut duration of stay markedly.

Primary hyperhidrosis interferes with social activities and requires an effective and safe treatment. We aimed to compare the therapeutic outcomes of unilateral single-port sympathicotomy and open surgery. Forty patients with primary palmar hyperhidrosis underwent sympathicotomy; 20 had open surgery, and 20 had video-assisted thoracic surgery. Complete resection of the T1 to T4 ganglia was performed by open surgery, and cutting and cauterization of the sympathetic chain between the T2 and T3 ganglia in the dominant hand was undertaken using video-assisted thoracic surgery. The patients were followed up at 1, 3, 6, and 12 months after surgery. The mean operative times were 39.6 ± 1.46 and 79.8 ± 1.53 min in the video-assisted thoracic surgery and open surgery group, respectively. The mean hospitalization was 2.2 ± 0.41 days after video-assisted thoracic surgery and 3.3 ± 0.47 days after open surgery. Complications included delayed hemothorax, compensatory hyperhidrosis, and wound infection. The mean blood loss during surgery and time to return to work were significantly less in the video-assisted thoracic surgery group. Excessive sweating was completely alleviated in the dominant hand in all patients, and in the opposite hand in 60% and 65% of the video-assisted thoracic surgery and open surgery group, respectively. Single-port sympathicotomy between the T2 and T3 ganglia ipsilateral to the dominant hand is a safe, minimally invasive, and effective treatment for primary palmar hyperhidrosis. Alleviation of excessive sweating in the opposite hand can also be achieved in a large proportion of these patients. © The Author(s) 2016.

Infrasonic wave accompanying a crack opening during the 2015 Hakone eruption

2018-03-01

To understand the initial process of the phreatic eruption of the Hakone volcano from June 29 to July 01, 2015, we analyzed infrasound data using the cross-correlation between infrasound and vertical ground velocity and compared the results of our analysis to the crustal deformation detected by tiltmeters and broadband seismometers. An infrasound signal and vertical ground motion due to an infrasound wave coupled to the ground were detected simultaneously with the opening of a crack source beneath the Owakudani geothermal region during the 2-min time period after 07:32 JST on June 29, 2015 (JST = UTC + 8 h). Given that the upper end of the open crack was approximately 150 m beneath the surface, the time for the direct emission of highly pressurized fluid from the upper end of the open crack to the surface should have exceeded the duration of the inflation owing to the hydraulic diffusivity in the porous media. Therefore, the infrasound signal coincident with the opening of the crack may reflect a sudden emission of volcanic gas resulting from the rapid vaporization of pre-existing groundwater beneath Owakudani because of the transfer of the volumetric strain change from the deformation source. We also noticed a correlation pattern corresponding to discrete impulsive infrasound signals during vent formation, which occurred several hours to 2 days after the opening of the crack. In particular, we noted that the sudden emission of vapor coincided with the inflation of the shallow pressure source, whereas the eruptive burst events accompanied by the largest vent formation were delayed by approximately 2 days. Furthermore, we demonstrated that the correlation method is a useful tool in detecting small infrasound signals and provides important information regarding the initial processes of the eruption.[Figure not available: see fulltext.

Early ambulation after open abdominal aortic aneurysm (AAA) surgery is assumed to play a key role in preventing postoperative complications and reducing hospital length of stay. However, the factors predicting early ambulation after open AAA surgery have not yet been sufficiently investigated. Here, we investigated which preoperative and intraoperative variables are associated with start time for ambulation in patients after open AAA surgery. A total of 67 consecutive patients undergoing open AAA surgery were included in the study [male, 62 (92 %); mean age, 68 years (range, 47-82 years), mean AAA diameter, 53 mm (range, 28-80 mm)]. Preoperative physical activity was examined by means of 6-min walk distance (6MWD) and a medical interview. Patients were divided into two groups, according to when independence in walking was attained: early group <3 days (n = 36) and late group ≥3 days (n = 31), and the pre-, intra-, and postoperative recovery data were compared. There were no significant differences in patient baseline characteristics or intraoperative data between the two groups. The number of patients engaging in preoperative regular physical activity and 6MWD were significantly greater (p = 0.042 and p = 0.034, respectively) in the early group than in the late group. In addition, time to hospital discharge was significantly shorter in the early group than in the late group (p = 0.031). Binary logistic regression analysis showed that preoperative regular physical activity was the only independent factor for identifying patients in the early group (odds ratio 2.769, 95 % confidence interval 1.024-7.487, p = 0.045). These results suggest that engaging in regular physical activity is an effective predictor of early ambulation after open AAA surgery.

The effect of aortic morphology on peri-operative mortality of ruptured abdominal aortic aneurysm.

PubMed

2015-06-01

To investigate whether aneurysm shape and extent, which indicate whether a patient with ruptured abdominal aortic aneurysm (rAAA) is eligible for endovascular repair (EVAR), influence the outcome of both EVAR and open surgical repair. The influence of six morphological parameters (maximum aortic diameter, aneurysm neck diameter, length and conicality, proximal neck angle, and maximum common iliac diameter) on mortality and reinterventions within 30 days was investigated in rAAA patients randomized before morphological assessment in the Immediate Management of the Patient with Rupture: Open Versus Endovascular strategies (IMPROVE) trial. Patients with a proven diagnosis of rAAA, who underwent repair and had their admission computerized tomography scan submitted to the core laboratory, were included. Among 458 patients (364 men, mean age 76 years), who had either EVAR (n = 177) or open repair (n = 281) started, there were 155 deaths and 88 re-interventions within 30 days of randomization analysed according to a pre-specified plan. The mean maximum aortic diameter was 8.6 cm. There were no substantial correlations between the six morphological variables. Aneurysm neck length was shorter in those undergoing open repair (vs. EVAR). Aneurysm neck length (mean 23.3, SD 16.1 mm) was inversely associated with mortality for open repair and overall: adjusted OR 0.72 (95% CI 0.57, 0.92) for each 16 mm (SD) increase in length. There were no convincing associations of morphological parameters with reinterventions. Short aneurysm necks adversely influence mortality after open repair of rAAA and preclude conventional EVAR. This may help explain why observational studies, but not randomized trials, have shown an early survival benefit for EVAR. ISRCTN 48334791. © The Author 2015.

In two 6-month, double-blind, placebo-controlled studies, rotigotine transdermal system was well-tolerated and efficacious monotherapy in early-stage PD. This post hoc analysis of the long-term open-label extensions (NCT00594165; NCT00599196) of these studies assessed incidence and severity of dyskinesia in participants treated with rotigotine, with or without concomitant levodopa, for up to 6 years. Open-label rotigotine was titrated to optimal dose (≤16 mg/24 h). Concomitant levodopa was permitted. Dyskinesia data, recorded using the Unified Parkinson's Disease Rating Scale Part IV, were pooled from the two open-label studies. Of 596 participants who received open-label rotigotine, 299 (50%) remained at trial closure; no patient discontinued due to dyskinesia. In the two studies, median exposure to rotigotine was 1910 days (∼5 years, 3 months), and 1564.5 days (∼4 years, 3 months). During up to 6 years of open-label rotigotine, 423/596 (71%) received levodopa. Dyskinesias were reported in 115/596 (19%) participants, 90/115 (78%) of who developed dyskinesia after levodopa was added; 25 reported dyskinesia in the absence of levodopa (includes patients who never received open-label levodopa, and those who reported dyskinesia before starting concomitant levodopa). Dyskinesia severity data were available for 107 of the 115 participants. In 56/107 (52%) participants, dyskinesia was considered 'not disabling' for all occurrences; the worst-case severity was 'mildly disabling' for 33/107 (31%), and 'moderately' or 'severely disabling' for 18/107 (17%; 3% of total participants). During treatment with rotigotine in patients with PD for up to 6 years the incidence of dyskinesia was low, and the dyskinesia was generally 'not disabling' or 'mildly disabling'.

Laparoscopically procured live donor kidney grafts are increasingly transplanted into pediatric recipients. The safety and efficacy of this changed surgical practice are unknown. Outcomes of laparoscopic vs open donor grafts in recipients 18 years and younger are equivalent. Retrospective review at an academic tertiary care referral center. Eleven consecutive pediatric recipients of laparoscopically procured kidneys between April 1, 1997, and December 31, 2001, were pair matched for age with 11 recipients of openly procured kidneys between December 1, 1991, and March 31, 1997; the 22 adult donors were also studied. Recipients: surgical complications, graft function and survival. Donors: perioperative morbidity and length of hospital stay. Twenty (91%) of 22 kidneys were donated by a parent of the recipient. In recipients of laparoscopically procured grafts, we observed significantly lower creatinine clearances and higher creatinine levels on days 1, 4, and 6, but by 1 month, graft function was similar in both groups. No significant differences in surgical complications, delayed function, acute and chronic rejection, and graft survival rates were found. No laparoscopic or open donor required blood transfusion, reoperation, or hospital readmission. One laparoscopic donor (9%) was converted to open nephrectomy. For laparoscopic vs open donors, median operative time was longer (difference, 67 min; P =.08), but median postoperative length of stay was significantly shorter (3 vs 5 days; P =.02). Laparoscopic live donor nephrectomy has no adverse impact on pediatric recipient outcomes. For donors, the laparoscopic operation is safe and the hospital stay is shortened. These results support the continued use of laparoscopically procured live donor kidneys in pediatric renal transplantation.

Previously, we have characterized two tonoplast intrinsic proteins (TIPs) and four plasma membrane intrinsic proteins (PIPs) from the 2-day-old petals of tulip (Tulipa gesneriana). In this study, we analyzed the development of tulip petals and stems, temperature-dependent petal movement, the amount of ³H₂O transported into petals and stems during petal movement, and the transcript levels of two TIP (TgTIP1;1 and TgTIP1;2) and four TgPIP genes in petals and stems, from the first day of petal opening to day 12. The development of the petals and stems was completed by days 6 and 9, respectively, after the first day of petal opening. Temperature-dependent petal movement and the amount of ³H₂O that was transported into petals could be detected at significant levels up to day 6 with petal movement reaching a peak at day 3. Real-time reverse transcription-polymerase chain reaction analysis revealed that TgTIP1;1 and TgTIP1;2 were expressed ubiquitously in petals, stems, leaves, bulbs and roots. However, the expression level of TgTIP1;2 was very low in bulbs. The expression of both TgTIP1 genes was upregulated in close association with the development of petals but not with that of the stem. The four TgPIP genes were expressed at almost the same level during the development of the petals and the stem. However, the levels of the TgTIP1 and TgPIP transcripts in petals decreased during the course of petal wilting from day 9 onwards. These results suggest that TgTIP1;1 and TgTIP1;2 may contribute to petal development. Copyright © Physiologia Plantarum 2012.

The influences of various diurnal stomatal opening patterns, spines, and ribs on the stem surface temperature and water economy of a CAM succulent, the barrel cactus Ferocactus acanthodes, were examined using an energy budget model. To incorporate energy exchanges by shortwave and longwave irradiation, latent heat, conduction, and convection as well as the heat storage in the massive stem, the plant was subdivided into over 100 internal and external regions in the model. This enabled the average surface temperature to be predicted within 1 C of the measured temperature for both winter and summer days. Reducing the stem water vapor conductance from the values observed in the field to zero caused the average daily stem surface temperature to increase only 0.7 C for a winter day and 0.3 C for a summer day. Thus, latent heat loss does not substantially reduce stem temperature. Although the surface temperatures averaged 18 C warmer for the summer day than for the winter day for a plant 41 cm tall, the temperature dependence of stomatal opening caused the simulated nighttime water loss rates to be about the same for the 2 days. Spines moderated the amplitude of the diurnal temperature changes of the stem surface, since the daily variation was 17 C for the winter day and 25 C for the summer day with spines compared with 23 C and 41 C, respectively, in their simulated absence. Ribs reduced the daytime temperature rise by providing 54% more area for convective heat loss than for a smooth circumscribing surface. In a simulation where both spines and ribs were eliminated, the daytime average surface temperature rose by 5 C. PMID:16660148

Phase 2a, Open-Label, 4-Escalating-Dose, Randomized Multicenter Study Evaluating the Safety and Activity of Ferroquine (SSR97193) Plus Artesunate, versus Amodiaquine Plus Artesunate, in African Adult Men with Uncomplicated Plasmodium falciparum Malaria.

Artemisinin-based combination therapies are recommended as first-line agents for treating uncomplicated Plasmodium falciparum malaria. Ferroquine, a 4-aminoquinolone, is a novel long-acting combination partner for fast-acting drugs like artesunate (AS). We did a small phase 2a, multicenter, open-label, safety-focused dose-ranging randomized study of ferroquine at three African hospitals: two Gabonese and one Kenyan. We recruited adult men with symptomatic uncomplicated P. falciparum monoinfection. Four escalating doses of ferroquine (100, 200, 400, and 600 mg) were assessed in sequence, versus an amodiaquine comparator. After a 2:1 randomization (block size three, equating to N = 12 for each ferroquine dose and N = 6 for each of four amodiaquine comparator groups) patients received daily for three consecutive days, either ferroquine + AS (200 mg/day) or amodiaquine (612 mg/day) + AS (200 mg/day). Safety, electrocardiograms, parasite clearance times, efficacy, and pharmacokinetics were assessed to day 28. Seventy-two patients were randomized. Ferroquine + AS showed generally mild increases (Grade 1 toxicity) in alanine aminotransferase (ALT) levels with a dose trend starting at 400 mg. There were two Grade 2 ALT events: one patient receiving 200 mg (3.8 upper limit of normal [ULN], day 7) and one receiving 600 mg (3.3 ULN, day 14), both without increased bilirubin. One ferroquine 100 mg + AS patient after one dose was withdrawn after developing a QTcF interval prolongation > 60 milliseconds over baseline. Parasitemias in all patients cleared quickly, with no recurrence through day 28. Hepatic, as well as cardiac, profiles should be monitored closely in future trials.

Prenatal exposure to valproic acid on gestational day 12.5 may lead to the impaired behavior in the offspring, which is similar to the human autistic symptoms. To the contrary, astaxanthin shows neuroprotective effect by its antioxidant mechanism. We aimed to (i) develop mice model of autism and (ii) investigate the effect of astaxanthin on such model animals. Valproic acid (600 mg/kg) was administered intraperitoneally to the pregnant mice on gestational day 12.5. Prenatal valproic acid-exposed mice were divided into 2 groups on postnatal day 25 and astaxanthin (2mg/kg) was given to the experimental group (VPA_AST, n=10) while saline was given to the control group (VPA, n=10) for 4 weeks. Behavioral test including social interaction, open field and hot-plate were conducted on postnatal day 25 and oxidative stress markers such as lipid peroxidation, advanced protein oxidation product, nitric oxide, glutathione, and activity of superoxide dismutase and catalase were estimated on postnatal day 26 to confirm mice model of autism and on postnatal day 56 to assess the effect of astaxanthin. On postnatal day 25, prenatal valproic acid-exposed mice exhibited (i) delayed eye opening (ii) longer latency to respond painful stimuli, (iii) poor sociability and social novelty and (iv) high level of anxiety. In addition, an increased level of oxidative stress was found by determining different oxidative stress markers. Treatment with astaxanthin significantly (p<0.05) improved the behavioral disorder and reduced the oxidative stress in brain and liver. In conclusion, prenatal exposure to valproic day in pregnant mice leads to the development of autism-like features. Astaxanthin improves the impaired behavior in animal model of autism presumably by its antioxidant activity. Copyright © 2015 Elsevier B.V. All rights reserved.
