Aim. The galactose single-point (GSP) test assesses functioning liver mass by measuring the galactose concentration in the blood 1 hour after its administration. The purpose of this study was to investigate the impact of hemodialysis (HD) on short-term and long-term liver function by use of GSP test.Methods. Seventy-four patients on maintenance HD (46 males and 28 females, 60.38 ± 11.86 years) with a mean time on HD of 60.77 ± 48.31 months were studied. The GSP values were compared in two groups: (1) before and after single session HD, and (2) after one year of maintenance HD.Results. Among the 74 HD patient, only the post-HD Cr levels and years on dialysis were significantly correlated with GSP values (r=0.280,P<0.05andr=-0.240,P<0.05, resp.). 14 of 74 patients were selected for GSP evaluation before and after a single HD session, and the hepatic clearance of galactose was similar (pre-HD 410 ± 254 g/mL, post-HD 439 ± 298 g/mL,P=0.49). GSP values decreased from 420.20 ± 175.26 g/mL to 383.40 ± 153.97 g/mL after 1 year maintenance HD in other 15 patients (mean difference: 19.00 ± 37.66 g/mL,P<0.05).Conclusions. Patients on maintenance HD for several years may experience improvement of their liver function. However, a single HD session does not affect liver function significantly as assessed by the GSP test. Since the metabolism of galactose is dependent on liver blood flow and hepatic functional mass, further studies are needed.

The Impact

This study extends the employee stock option literature by examining the impact of accrual management, before and after stock option exercise, on the timing of sales of shares acquired at exercise. We find evidence that accrual management prior to exercise is positively associated with the decision to quickly sell shares after exercise, facilitating a short-term exercise-and-sell strategy. Alternatively, we find that, among executives initially choosing to hold at exercise, tax incentives appear to drive both post-exercise accrual management and the timing of sale transactions. Specifically, our results suggest that executives use income-increasing accruals during the holding period to bolster their stock option gains sand then sell immediately after satisfying the minimum (twelve month) holding period for long-term capital gain treatment. These results provide context for prior research that found evidence of earnings management leading up to option exercise on the expectation of an immediate sale.

The Impact

This paper investigates the impact of the Employment Contracts Act on trade union membership. Two separate surveys of labour market participants lvere conducted in Dunedin on the eve of the legislation and one year later. The findings demonstrated that for these samples, trade union membership in aggregate was not based on compulsion before the legislation and remained at a similar level a year later. Democracy was not restored to the workplace it was already apparent there. This implies that changes in the industrial relations system had already taken place prior to the legislation and it is suggested that these findings are explicable if the effect of the exigencies of the recession on both parries is taken account of In the ensuing discussion, reasons for the persistence of the same level of union membership after the legislation were considered. It was demonstrated that most members li'anted the union to act as their bargaining agent and felt few pressures regarding their choice of employment contract. In other words, employers did not utilise the provisions of the Act to weaken union membership, at least in the short term.

Pulmonary Ventilation Function

Objective: Ventilation attenuation often happened in professional divers due to long-term cumulative effects in diving exercises. By case-control experiments, we observed the immediate effects of pulmonary ventilation before and after the exposure of 12m-depth underwater for 20 min to discuss the relationships between the short-term and long-time effects caused by diving environment. Methods: Participants were randomly assigned into the Experimental Group (EG) who stayed for 20 min under 12-m water environment or the Control Group (CG) who stayed in hyperbaric chamber under the pressure of 2.2ATA. Pulmonary ventilation function parameters including VC, FVC, MVV and MV were detected respectively before and after hyperbaric exposure by the Spirometer. Immediate effects of pulmonary ventilation before and after diving were compared by paired t test to reveal the different influence caused by environmental pressure. Results: The value of VC appears to rise while the MV, MVV were detected decreased after the exposure of 2.2ATA of environment pressure for 20min in the two groups. VC increased more significantly in the CG (t=-1.26, p=0.23) after hyperbaric exposure, that leads to the FEV1.0%t (=FEV1.0/VC %) increase in EG (t=-0.73, p=0.48) while decrease in CG (t=0.42, p=0.17). The same trend in VC, MV and MVV after high pressure exposure in the two groups mainly due to the effect of common factors –the pressure. In addition to the impact of the pressure itself, EG members also face diving related immersion effect, influence of diving equipment load and water under low temperature. The FVC is detected decreased in EG (t=1.21, P =0.25) while it increased in CG (t=-0.42, P =0.68) , but the differences are not significant and couldn’t affect the measured FEV1.0% (=FEV1.0/FVC %) values showed both increasing in EG (t=-1.48, P =0.16) and in CG (t=-0.23, P =0.82). The expiratory flow rate including PEF, FEF25-75, MEF75, MEF50 increased in EG (t are -0.72, -0.69, -0.87 and -0.36 respectively with P all greater than 0.05) while decreased in CG (t are 1.67, 0.50, 1.53 and 0.71 respectively with P all greater than 0.05). MEF25 is the expiratory flow index of not affected by respiratory muscle force and the measured values of MEF25 increased in the EG (t=-0.68, P =0.51) and in the CG (t=-0.36, P =0.72). Conclusion: Water immersion and water temperature during diving exposure could cause and accelerate hemodynamic changes in pulmonary circulation induced pulmonary interstitial edema and led to the increase of external respiratory work. Instant effects of diving exposure in the study are quite consistent with the long-term cumulative effect of professional divers in previous research, which is FVC reduced because small airway become narrower. The results illustrate even the small depth of short-range diving exercise have definite influences on pulmonary ventilation, which mainly comes from the environmental factor but not the pressure increases.

Accident Statistics

The impact of metrication of roadside speed signs upon vehicle speeds was investigated for four different road types using concealed roadside radar. The study was conducted one year after metrication to determine whether there were any long-term changes in traffic patterns in addition to the short-term influences reported previously. There was no evidence for any tendency for drivers to increase traveled speed on roads for which metrication resulted in an increase in the speed limit. Analysis of accident statistics for the month following metrication revealed no significant increase in accident rate over that projected from nine-year accident trends. It is concluded that highway metrication does not present the safety hazard suggested by critics of the metrication program.

The Impact

This paper analyzes the impact of fieldwork on the development of students’ mental models concerning glaciers and their effects on the landscape. Data were collected by means of an open-ended questionnaire that was administered to 279 pre-service teachers before and after an educational field trip, which analyzed its impact on short-term and long-term outcomes. In general, students’ mental models about how glaciers function and how they create landforms are relatively simplistic and incomplete. Students are unaware of the major erosional properties associated with glaciers and many of them do not specify that glaciers are bodies of ice that have a tendency to move down slope. The analysis of the data yielded four mental model categories. Fieldwork influenced the short-term effects on mental model development even though its positive impact decreases over time. Mental models including scientific views were only found in the post-instruction group. On the other hand, the pre-instruction group was strongly influenced by a catastrophic event that occurred in the region in 1959 (the Ribadelago flooding), which interferes with students’ mental reasoning on the formation of landscape features. This way of thinking is reinforced and/or mixed with a religious myth (Villaverde de Lucerna legend), which also invokes a catastrophic origin of the lake. In this case, this includes mystic flooding.

The Impact

This paper shows the impact of eco-driving training course on driving behaviour of 7 drivers, analysing two internal parameters: Scania Driver Support (SDS) parameter and Fuel Consumption (FC). Data were collected using Scania Fleet Management System (Scania FMS) over a period of one-year (1 + 2 + 4 + 6 months during the 2015 and 2016). Data for these two parameters of all drivers were recorded daily over a one-year period and calculated in average values on a monthly basis. A one-year cycle of average monthly ambient temperatures of wider geographical region was adopted as the most important external parameter of impact on eco-driving benefits. Longitudinal observation period is divided into: one month initial period of establishing the parameter values before the training (one month), short-term with eco-driving (two months), short-term without eco-driving (four months) and long-term (six months). Significantly higher values of SDS parameter (p < 0.05) and significant reduction of FC (p = 0.0310 < 0.05) were established with a higher average ambient temperature over a short-term period. A partial increase of SDS parameter value (p < 0.10) was established over a long-term period but the level of FC reversed to the values as before the training (p = 0.7554 > 0.05). The results indicate the potential of eco-driving training that manifests significantly positive effects only in good driving conditions. With bad weather conditions that correlate with bad driving conditions, the effects of eco-driving training are supressed with increased requirements for safer driving. Primary conclusion of the paper is that the eco-driving training principles have an apparent positive effect on reduction of FC and CO2 emission but are at the same time sensitive to environmental driving conditions.

OBJECTIVEIn 2017, Michigan passed new legislation designed to reduce opioid abuse. This study evaluated the impact of these new restrictive laws on preoperative narcotic use, short-term outcomes, and readmission rates after spinal surgery.METHODSPatient data from 1 year before and 1 year after initiation of the new opioid laws (beginning July 1, 2018) were queried from the Michigan Spine Surgery Improvement Collaborative database. Before and after implementation of the major elements of the new laws, 12,325 and 11,988 patients, respectively, were treated.RESULTSPatients before and after passage of the opioid laws had generally similar demographic and surgical characteristics. Notably, after passage of the opioid laws, the number of patients taking daily narcotics preoperatively decreased from 3783 (48.7%) to 2698 (39.7%; p < 0.0001). Three months postoperatively, there were no differences in minimum clinically important difference (56.0% vs 58.0%, p = 0.1068), numeric rating scale (NRS) score of back pain (3.5 vs 3.4, p = 0.1156), NRS score of leg pain (2.7 vs 2.7, p = 0.3595), satisfaction (84.4% vs 84.7%, p = 0.6852), or 90-day readmission rate (5.8% vs 6.2%, p = 0.3202) between groups. Although there was no difference in readmission rates, pain as a reason for readmission was marginally more common (0.86% vs 1.22%, p = 0.0323).CONCLUSIONSThere was a meaningful decrease in preoperative narcotic use, but notably there was no apparent negative impact on postoperative recovery, patient satisfaction, or short-term outcomes after spinal surgery despite more restrictive opioid prescribing. Although the readmission rate did not significantly increase, pain as a reason for readmission was marginally more frequently observed.

Abstract Interventions using exercise video games, or exergames, have shown short-term cognitive and physical benefits to older adults, though long-term effects are less promising. Enjoyment of exergames may promote exergame use after the intervention period, though little work has examined older adults’ views of exergames before and after gameplay experience. We invited 20 older adults between 65 and 84 years of age (M=73.30, SD=5.95) to play two Xbox Kinect games, Just Dance and Kinect Sports Rivals, for twenty minutes. In our presentation, we will present qualitative and quantitative findings of this pilot study, including findings that older adults reported that they were not likely to play similar exergames in the future and that they did not find the exergames to be more fun compared to other ways of exercising. We will discuss implications for game design and research relevant to game developers, manufacturers, and researchers. Part of a symposium sponsored by Technology and Aging Interest Group.
