Laparoscopic Splenectomy in Hemodynamically Stable Blunt Trauma

Background and Objectives: No criteria define indications for laparoscopic splenectomy in trauma. This investigation compared characteristics of trauma patients and outcomes between laparoscopic and open splenectomies. Methods: Patients were identified retrospectively by using ICD-9 codes. Included patients were 18 or older, with a blunt splenic injury from January 1, 2011, through December 31, 2014, and required splenectomy. Excluded patients had penetrating trauma, successful nonoperative management, or successful embolization. Variables included demographics, presenting characteristics, injury severity scores, abdominal abbreviated injury scores, splenic injury grade, surgical indication and approach (open or laparoscopic), surgery length, intra-operative blood loss, transfusions, length of stay, complications, mortality, and discharge disposition. Results: Forty-one patients underwent open splenectomy, and 11 underwent laparoscopic splenectomy. The mean age was 48.7 years, and men comprised the sample majority (36/52). The groups were well matched for age, abdominal injury scores, and admission vital signs. The open group had a significantly lower level of consciousness and more acidosis compared with the laparoscopic group. Most laparoscopic splenectomies were performed after failed nonoperative management or embolization. The indications for open splenectomy were a positive focused assessment with sonography for trauma and computed tomography results. Laparoscopic patients had significantly longer times between presentation and surgery and longer operations, but had significantly less blood loss and fewer transfusions compared with the open group. There were no differences in mortality, length of stay, complications, or discharge dispositions. Conclusion: Laparoscopic splenectomy is useful in patients with blunt trauma in whom conservative management produced no improvement and who do not have other injuries to preclude laparoscopy.
Information Spillover Dynamics of the Energy Futures Market Sector: A Novel Common Factor Approach

We investigate sector level information spillovers from energy to other futures market sectors using a novel conditionally heteroscedastic common factor (CHCF). CHCF represents common trends of macroeconomic influences on futures markets. We find that energy sector has the highest degree of commonality compared to other sectors. Conditional correlations between energy and non-energy sectors are highly persistent. The volatility spillover from the energy sector is prominent compared with mean and extreme market risk spillovers. Extreme risk spillovers from the energy to other sectors have an asymmetric effect. Shocks to energy futures have a significant potential impact on other markets during crises.
Assessing m-Health success in Bangladesh: An empirical investigation using IS success models

Mobile health, i.e. m-Health possesses huge potential, especially to the developing countries and remote locations of developed countries. The success of such systems may create a healthier society through eradicating health incidents, which cannot otherwise be addressed with “brick and mortar” type of health systems. The purpose of this paper is to develop an m-Health success model from users’ perspective and validate in a developing country context. ,Epistemologically, positivist approach has been adopted for the current research. An initial research model was developed from existing information system (IS) literature, which was then validated with survey data applying partial least square structural equation modelling (PLS-SEM). ,The results summarise that continuance intention (CI) of m-Health services is dependent on perceived value (PV) and user satisfaction (STF); PV positively influences STF. Moreover, platform quality, quality of medical advice, and interaction quality have positive and direct effect on PV and STF; finally, CI drives to better quality of health life. ,The findings of this study provide strategic implications to health managers and practitioners recognising the determinants of m-Health success and comprehending their relationships. It is underscored that, in order to secure the success of an m-Health system in a given society both human and technology-related components are vital and therefore should be taken care of. ,This is the first attempt that develops and validates an m-Health system success model, particularly from the context of a country with low-health profile. Moreover, the contextualisation of the related variables and extension of existing IS success models is theoretically original.
Prospective study of X‐linked progressive muscular dystrophy in campania

Within the Campania region of southern Italy a prospective study on X‐linked progressive muscular dystrophy was conducted over a period of 12 years from 1969 to 1980, inclusive. The mean incidence rate was 21.7 per 100,000 male livebirths for Duchenne muscular dystrophy (DMD) cases and 3.2 per 100,000 male livebirths for Becker muscular dystrophy (BMD) cases. The familial cases were 38.5% among the DMD patients and 50% among the BMD patients. Myocardial involvement appeared in DMD patients at about 6 years of age in a high percentage of cases and increased progressively until the last years of life, when cardiac damage occurred in 95% of cases. The percentage of myocardial involvement in BMD patients was very low before 13 years of age, but increased progressively until 20 years, when cardiac damage occurred in 80% of cases studied; severe cardiomyopathy did not occur before the age of 21. The data reported also include the effects of age on physical performance, serum creatine kinase activity and serum myoglobin levels, the types of cardiac damage, and the causes of death.
[Assessment of ivermectin therapeutic efficacy on fourth-stage larvae of Lagochilascaris minor in experimentally infected cats].

In order to verify the action of ivermectin against fourth-stage larvae of Lagochilascaris minor, thirty cats were divided into three groups (I, II and III). Each animal was inoculated orally with 50 third-stage larvae. The cats from groups I and II were treated with Ivermectin (200/mg/kg/single dose/sc via) on fifth day after inoculation (DAI). Treatment evaluation was performed between 30 and 40 DAI (group I) and between 180 to 190 DAI (group II) using parasite macroscopic and microscopic research at autopsy. The 10 cats from group III were untreated (control group). The authors observed 100% drug efficacy, at all observation periods, by total interruption of parasite's biological cycle in each of the treated animals. All the control group developed Lagochilascaris minor infection.
Effect of Coadministered Fat on the Tolerability, Safety, and Pharmacokinetic Properties of Dihydroartemisinin-Piperaquine in Papua New Guinean Children with Uncomplicated Malaria

ABSTRACT Coadministration of dihydroartemisinin-piperaquine (DHA-PQ) with fat may improve bioavailability and antimalarial efficacy, but it might also increase toxicity. There have been no studies of these potential effects in the pediatric age group. The tolerability, safety, efficacy, and pharmacokinetics of DHA-PQ administered with or without 8.5 g fat were investigated in 30 Papua New Guinean children aged 5 to 10 years diagnosed with uncomplicated falciparum malaria. Three daily 2.5:11.5-mg-base/kg doses were given with water (n = 14, group A) or milk (n = 16, group B), with regular clinical/laboratory assessment and blood sampling over 42 days. Plasma PQ was assayed by high-performance liquid chromatography with UV detection, and DHA was assayed using liquid chromatography-mass spectrometry. Compartmental pharmacokinetic models for PQ and DHA were developed using a population-based approach. DHA-PQ was generally well tolerated, and initial fever and parasite clearance were prompt. There were no differences in the areas under the concentration-time curve (AUC0–∞) for PQ (median, 41,906 versus 36,752 μg · h/liter in groups A and B, respectively; P = 0.24) or DHA (4,047 versus 4,190 μg · h/liter; P = 0.67). There were also no significant between-group differences in prolongation of the corrected electrocardiographic QT interval (QTc) initially during follow-up, but the QTc tended to be higher in group B children at 24 h (mean ± standard deviation [SD], 15 ± 10 versus 6 ± 15 ms0.5 in group A, P = 0.067) and 168 h (10 ± 18 versus 1 ± 23 ms0.5, P = 0.24) when plasma PQ concentrations were relatively low. A small amount of fat does not change the bioavailability of DHA-PQ in children, but a delayed persistent effect on ventricular repolarization cannot be excluded.
Nanoporosity improved water absorption, in vitro degradability, mineralization, osteoblast responses and drug release of poly(butylene succinate)-based composite scaffolds containing nanoporous magnesium silicate compared with magnesium silicate

Bioactive composite macroporous scaffold containing nanoporosity was prepared by incorporation of nanoporous magnesium silicate (NMS) into poly(butylene succinate) (PBSu) using solvent casting–particulate leaching method. The results showed that the water absorption and in vitro degradability of NMS/PBSu composite (NMPC) scaffold significantly improved compared with magnesium silicate (MS)/PBSu composite (MPC) scaffold. In addition, the NMPC scaffold showed improved apatite mineralization ability, indicating better bioactivity, as the NMPC containing nanoporosity could induce more apatite and homogeneous apatite layer on the surfaces than MPC scaffold. The attachment and proliferation of MC3T3-E1 cells on NMPC scaffold increased significantly compared with MPC scaffold, and the alkaline phosphatase (ALP) activity of the cells on NMPC scaffold was expressed at considerably higher levels compared with MPC scaffold. Moreover, NMPC scaffold with nanoporosity not only had large drug loading (vancomycin) but also exhibited drug sustained release. The results suggested that the incorporation of NMS into PBSu could produce bioactive composite scaffold with nanoporosity, which could enhance water absorption, degradability, apatite mineralization and drug sustained release and promote cell responses.
Ontogenesis of within-session locomotor habituation in the open field

Habituation signifies a decreased response to a constant or repeated stimulus or environment. Although habituation is a fundamental form of nonassociative learning, little is known about its ontogenesis. Here, locomotor activity of postnatal ferrets within individual open field sessions was quantitatively analysed. The patterns of activity revealed a gradual shift across developmental time between relative increment and decrement of activity within sessions. The increment-to-decrement turning point was around postnatal day 48. These novel findings indicate that systematic changes in the interplay between mechanisms that drive exploratory behaviour and those that inhibit it shape the ontogenesis of open field habituation. The remarkable robustness of the data underscores the suitability of the ferret as an experimental animal for investigating ontogenesis of habituation.
The time course from gender categorization to gender-stereotype activation

ABSTRACT Social categorization is the foundation of stereotype activation, and the process from social categorization to stereotype activation is rapid. However, the time from social categorization to stereotype activation is unknown. This study involves a real-time measurement of the time course of gender-stereotype activation beginning with gender categorization using event-related potential technology with a face as the priming stimulus. We found that 195 ms after a face stimulus was presented, brain waves stimulated by male or female gender categorization showed a clear separation, with male faces stimulating larger N200 waves. In addition, 475 ms after a face stimulus appeared or 280 ms after the gendercategorization process occurred, gender-stereotype-consistent and gender-stereotype-inconsistent stimuli were distinct, with gender-stereotype-inconsistent stimuli inducing larger N400 waves. These results indicate that during gender-stereotype activation by face perception, gender categorization occurs approximately 195 ms after seeing a face stimulus and a gender stereotype is activated at approximately 475 ms.
A pilot prospective study on the consultation and relational empathy, patient enablement, and health changes over 12 months in patients going to the Glasgow Homoeopathic Hospital.

OBJECTIVE To relate prospectively initial consultation characteristics-length, empathy, and patient enablement- with perceived health changes in patients going to the Glasgow Homoeopathic Hospital (GHH). METHODS Consecutive outpatients completed the Consultation and Relational Empathy (CARE) measure and the Patient Enablement Instrument (PEI) immediately after their first consultations, again at 3 months, and the PEI also at 12 months. The Short Form-12 was completed immediately before and the Measure Yourself Medical Outcome (MYMOP) Profile during the first consultation, and both were repeated at 3 and 12 months. Perceived changes in main complaint and well-being were assessed using the Glasgow Homoeopathic Outcome Scale (GHHOS). RESULTS Empathy score at first consultation was highly predictive of ongoing empathy score at 3 months (Spearman's rho, 0.572, p < 0.0001). Empathy scores at first consultation also correlated significantly with enablement score at first consultation (rho, 0.325, p < 0.0001) and overall enablement at 12 months (rho, 0.281; p < 0.05). Controlling for the number of subsequent consultations, initial empathy scores were also predictive of change in main complaint, and general well-being, at 3 months (rho, 0.225, 0.213 respectively; p < 0.05). Enablement score at first consultation also predicted overall enablement at 3 months (rho, 0.255; p < 0.05) and 12 months (rho, 0.282; p < 0.05). Initial enablement predicted GHOSS well-being score at 3 months after controlling for number of consultations (rho, 0.279; p < 0.05). Both empathy and enablement at 3 months predicted overall enablement at 12 months (rho, 0.327; p < 0.01 and rho, 0.577; p < 0.0001, respectively). Empathy at 3 months was not significantly related to GHHOS scores at 12 months, whereas enablement scores at 3 months were highly predictive of both GHHOS main complaint and well-being scores at 12 months (rho, 0.459 and 0.507, respectively; p < 0.0001). Empathy and enablement scores did not correlate significantly with changes in SF-12 and MYMOP scores at any of the time points. The length of the first consultation was related to initial and subsequent CARE scores, overall enablement, and GHHOS scores at 3 and 12 months. CONCLUSIONS Empathy is crucial for enablement, which, in turn, is strongly related to perceived change in main complaint and well-being. The length of time the clinician spends with a patient at initial consultation appears to be an important factor in these complex relationships among process and outcome.
Percutaneous pulmonary artery denervation completely abolishes experimental pulmonary arterial hypertension in vivo.

AIMS The study sought to assess the effect of percutaneous pulmonary artery denervation (PADN) on balloon-occlusion-induced acute pulmonary arterial hypertension (PAH) in vivo. The PADN is a minimally invasive and endovascular catheter-based interventional therapy using radiofrequency ablation to abolish the pulmonary arterial baroreceptors to pressure response. METHODS AND RESULTS To examine the efficacy of balloon-occlusion-induced PAH, twenty Mongolian dogs were randomly assigned to one of two groups: group 1 (left distal pulmonary basal trunk occlusion) and group 2 (left pulmonary interlobar artery occlusion). Afterwards, PADN treatment at the main pulmonary artery bifurcation level with left pulmonary interlobar artery occlusion in all 20 dogs was conducted. Haemodynamic parameters were measured at baseline and during balloon occlusion as well as the PADN treatment at different time points: one, two, three, five, and ten minutes. Before the PADN treatment, most haemodynamic parameters of the pulmonary artery remained unchanged in group 1 with distal pulmonary basal trunk occlusion. However, in group 2 with the occlusion of the left pulmonary interlobar artery, mean pulmonary arterial pressure, mean right ventricular pressure, and pulmonary vessel resistance gradually increased, and mean absolute difference reached peak at five minutes (Δ16.6 mmHg, Δ14.1 mmHg and Δ1,144 dye/s/cm5, respectively; each p<0.01). These haemodynamic parameters at five minutes induced by left pulmonary interlobar artery occlusion were completely abolished with the PADN treatment compared to baseline (Δ0.3 mmHg, Δ0.2 mmHg, and Δ34 dye/s/cm5, respectively). CONCLUSIONS Balloon occlusion of the left pulmonary interlobar artery led to a significant increase of haemodynamic parameters of the pulmonary artery. The pressure responses were completely abolished by the PADN treatment at the main bifurcation area of the left pulmonary artery.
Effects of mycophenolic acid on IL-6 expression of human renal proximal and distal tubular cells in vitro.

BACKGROUND Interleukin-6 (IL-6) is a multifunctional cytokine which regulates immune responses and host defence mechanisms. IL-6 has been found to be increased in certain inflammatory conditions of the kidney, in which tubular epithelial cells play a pivotal role. Human renal tubular cells express IL-6. Until now no data about the effect of the immunosuppressant drug mycophenolic acid (MPA) on IL-6 expression were available. METHODS Proximal and distal tubular epithelial cells (PTC/DTC) have been isolated immunomagnetically. Confluent monolayers were stimulated with interleukin-1beta (IL-1beta; 25 U/ml), IL-1beta+ MPA (0.25-50 micro M) or MPA alone for 48 h. Release of IL-6 protein into the supernatant was evaluated with an enzyme immunoassay, IL-6 mRNA expression was evaluated using the Quantikine mRNA kit. RESULTS After IL-1beta stimulation, a highly significant 2.6- (PTC) and 3.8-fold (DTC) upregulation of IL-6 expression was detectable. IL-6 mRNA was upregulated by IL-1beta [1.57- (PTC) and 2.03-fold (DTC)]. MPA inhibited this cytokine-induced IL-6 expression in a dose-dependent manner. Incubation with the lowest MPA concentration had no effect on the stimulated upregulation, whereas all higher doses significantly decreased IL-6 expression. Dexamethasone significantly inhibited the cytokine-induced IL-6 protein release in PTC, but not in DTC. CONCLUSIONS In this study we demonstrated for the first time an inhibitory effect of MPA on the stimulated IL-6 expression of renal tubular epithelial cells. In contrast to older data, which showed a synergistic upregulation of the expression of a CC-chemokine by a combination of cytokines and MPA, in the present study we could demonstrate an immunosuppressive effect of MPA on the expression of an important cytokine.
Screening for Multidrug-Resistant Bacteria as a Predictive Test for Subsequent Onset of Nosocomial Infection

Objective. To investigate whether carriage of multidrug-resistant bacteria is a risk factor for nosocomial infection and whether detection of carriage is predictive of subsequent onset of nosocomial infection. Methods. In this observational cohort (study period, June 1998 through October 2002), nasal and rectal swab specimens from 412 consecutive patients admitted to the intensive care unit were tested for carriage of multidrug-resistant bacteria. Concomitantly, the bacteria responsible for any subsequent nosocomial infection, the date of infection, and some of the known clinical risk factors for nosocomial infection were noted. These factors were adjusted for potential confounders, using a Cox model stratified on the propensity score of multidrug-resistant bacteria carriage. The diagnostic characteristics of a carriage test, including the positive and negative diagnostic likelihood ratios, were calculated for all strata of the propensity score. Results. Forty-two patients were carrying multidrug-resistant bacteria. Nosocomial infection occurred in 95 patients, of whom 16 (38%) were carriers, and 79 (83%) were noncarriers (P = .01). After adjustment for potential confounders, statistical analysis revealed that carriage remained a risk factor for nosocomial infection (relative risk, 2.08 [95% confidence interval {CI}, 1.13-3.81]). Receipt of antibiotic treatment at the time of intensive care unit admission was found to be protective against nosocomial infection. A positive result of test for detection of carriage seemed to be an efficient predictor of subsequent nosocomial infection (positive diagnostic likelihood ratio, 2.05 [95% CI, 1.15-3.66]), although a negative test result was not a predictor of subsequent nosocomial infection (negative likelihood ratio, 0.91 [95% CI, 0.73-1.11]). Conclusion. Carriage proved to be a risk factor for subsequent nosocomial infection. However, the carriage test was useful as a predictive tool only for patients with a positive test result.
Blood Pressure and White-Matter Disease Progression in a Biethnic Cohort: Atherosclerosis Risk in Communities (ARIC) Study

Background and Purpose— Blood pressure (BP) is a predictor of concurrent and subsequently measured white-matter hyperintensity (WMH), but longitudinal studies of WMH changes and data in black participants are lacking. We hypothesized that WMH progression would be (1) strongly related to BP in blacks and whites and (2) predicted more strongly by earlier (midlife) or cumulative BP measurements than by measures at older ages. Methods— Participants were 983 individuals (49% black) from the Atherosclerosis Risk in Communities (ARIC) Study who underwent cerebral magnetic resonance imaging in 1993–1995 and 2004–2006. Associations between BP (measured at each of 5 visits, in addition to a time-averaged cumulative BP) and progression of WMHs were analyzed and compared. Results— Cumulative systolic BP (SBP) was the strongest BP predictor of WMH progression in adjusted models. Higher cumulative SBP (by 20 mm Hg) was associated with greater progression of WMHs and was similar in blacks (2.5 cm3, P<0.0001) and whites (2.6 cm3, P<0.0001). Higher cumulative SBP (per 20 mm Hg) was also associated with being in the top quintile of WMH progression (adjusted odds ratio=2.0; 95% CI, 1.6 to 2.6). Earlier SBP measurements were stronger predictors of WMH progression than were later SBP measurements, but in blacks only. Conclusions— In this population-based cohort, cumulative SBP was a stronger predictor of WMH progression than SBP from individual visits, in both blacks and whites. Earlier BPs were stronger predictors than BPs measured at later time points in blacks only.
