To assess soft tissues healing at immediate transmucosal implants placed into molar extraction sites with buccal self-contained dehiscences. For this 12-month controlled clinical trial, 15 subjects received immediate transmucosal tapered-effect (TE) implants placed in molar extraction sockets displaying a buccal bone dehiscence (test sites) with a height and a width of > or =3 mm, respectively. Peri-implant marginal defects were treated according to the principles of Guided Bone Regeneration (GBR) by means of deproteinized bovine bone mineral particles in conjunction with a bioresorbable collagen membrane. Fifteen subjects received implants in healed molar sites (control sites) with intact buccal alveolar walls following tooth extraction. In total, 30 TE implants with an endosseous diameter of 4.8 mm and a shoulder diameter of 6.5 mm were used. Flaps were repositioned and sutured, allowing non-submerged, transmucosal soft tissues healing. At the 12-month follow-up, pocket probing depths (PPD) and clinical attachment levels (CAL) were compared between implants placed in the test and the control sites, respectively. All subjects completed the 12-month follow-up period. All implants healed uneventfully, yielding a survival rate of 100%. After 12 months, statistically significantly higher (P<0.05) PPD and CAL values were recorded around implants placed in the test sites compared with those placed in the control sites. The findings of this controlled clinical trial showed that healing following immediate transmucosal implant installation in molar extraction sites with wide and shallow buccal dehiscences yielded less favorable outcomes compared with those of implants placed in healed sites, and resulted in lack of 'complete' osseointegration.

Effects of buspirone on the immediate positive and delayed negative properties of intravenous cocaine as measured in the conditioned place preference test

In prior work, we have demonstrated that the behavioral effects of cocaine adhere to the predictions of the opponent-process theory of drug action. Animals develop conditioned place preferences for distinct locations paired with the immediate effects of IV cocaine, but learn to avoid places paired with the effects present 15-min post injection. It was of interest to assess the putative role of 5-HT in producing the negative properties of cocaine since cocaine acts to inhibit the reuptake of serotonin (5-HT) and since such actions have been associated with anxiogenic consequences. Male rats were administered a reinforcing dose of cocaine (1.0 mg/kg IV) and then placed – either immediately or after a 15-min delay -- into one side of a two-compartment (black-white) Conditioned Place Preference (CPP) box for 5-min. On alternate days, the animals received IV saline injections and were placed in the opposite side of the CPP box. This continued for eight days after which animals had experienced 4 pairings of cocaine with one side (black or white) of the CPP apparatus, and 4 saline pairings with the opposite side. Other groups of rats were treated identically except that 30-min prior to placement into the apparatus, these animals received an IP injection of saline or buspirone (a partial 5-HT1A agonist) at a dose that we have shown to be anxiolytic (2.5 mg/kg IP). Control animals experienced either buspirone or saline pretreatments without cocaine. Our results confirm that animals increase the time spent on the side paired with the immediate effects of cocaine (compared to baseline), but tend to avoid the side paired with effects present 15-min post-injection. Buspirone had no effect on the immediate rewarding properties of cocaine, but completely reversed the negative properties present 15-min post-cocaine. These results are consistent with the view that attenuation of 5-HT neurotransmission (via the autoreceptor agonist properties of buspirone) can reverse the negative

This 5-year prospective multicenter study compared implant survival and success, peri-implant health and soft tissue responses, crestal bone level stability, and complication rates following immediate loading of single OsseoSpeed implants placed in anterior maxillary healed ridges or extraction sockets. Individuals requiring anterior tooth replacement with single implants were treated and immediately provisionalized. Definitive all-ceramic crowns were placed at 12 weeks. Implant survival, bone levels, soft tissue levels, and peri-implant health were monitored for 5 years. One hundred thirteen patients received implants in fresh sockets (55) and healed ridges (58). After 5 years, 45 and 49 patients remained for evaluation, respectively. During the first year, three implants failed in the extraction socket group (94.6% survival) and one implant failed in the healed ridge group (98.3% survival); this difference was not significant. No further implant failures were recorded. After 5 years, the interproximal crestal bone levels were located a mean of 0.43 ± 0.63 mm and 0.38 ± 0.62 mm from the reference points of implants in sockets and healed ridges (not a significant difference). In both groups, papillae increased over time and peri-implant mucosal zenith positions were stable from the time of definitive crown placement in sockets and healed ridges. Compared to flap surgery for implants in healed ridges, flapless surgery resulted in increased peri-implant mucosal tissue dimension (average, 0.78 ± 1.34 mm vs 0.19 ± 0.79 mm). After 5 years, the bone and soft tissue parameters that characterize implant success and contribute to dental implant esthetics were similar following the immediate provisionalization of implants in sockets and healed ridges. The overall tissue responses and reported implant survival support the immediate provisionalization of dental implants in situations involving healed ridges and, under ideal circumstances, extraction sockets.

The purpose of this study was to determine the effect of cigarette smoking and residual native bone height on the survival of dental implants placed immediately in grafted sinuses. In this retrospective study, 334 subject records were screened, and 75 subjects (155 implants) were included. Data collection based on treatment notes and radiographs included age, sex, smoking status, sinus floor bone height, dental implant information, and implant survival. The survival rates of implants for nonsmokers and smokers at stage-two surgery were 93% and 84%, respectively. After 12 months of functional loading, the survival rates of implants for nonsmokers and smokers were 87% (81 of 93) and 79% (49 of 62), respectively (P < .000). Analysis revealed that the effect of smoking on implant survival is significant when the preoperative bone height is less than 4 mm, with an 82.4% implant survival rate in nonsmokers compared to 60% in smokers (P < .05). Smoking should be considered as a high risk factor when implants are placed immediately in grafted sinuses, particularly in areas of limited bone height.

To evaluate the efficacy of immediate loading versus early loading at 6 weeks of bar-retained mandibular overdentures supported by two implants placed with a flapless technique. Sixty patients were randomised: 30 to the immediately loaded group and 30 to the early loaded group. To be immediately loaded, implants had to be inserted with a minimum torque > 48 Ncm. Outcome measures were prosthesis and implant failures, biological and biomechanical complications, patient satisfaction, and Implant Stability Quotient (ISQ) assessed with a resonance frequency analysis instrument. Sixty implants were placed in each group. Flaps had to be raised in nine patients to check drill direction or to better visualise the area after multiple teeth extraction. Two implants in two patients did not reach the planned insertion torque and were immediately replaced by larger diameters ones. After 1 year no drop out occurred and two early loaded implants failed in two patients. There were no statistically significant differences between groups for prosthesis failures, implant losses, complications, and mean ISQ values; however, patients in the immediately loaded group were significantly more satisfied than those loaded early. When comparing mean ISQ values taken 6 weeks after placement with 1-year data within each group, values decreased significantly. Mandibular overdentures can be successfully loaded the same day of implant placement with a minimally invasive surgery, increasing patient satisfaction while decreasing treatment time and patient discomfort. No apparent advantages were seen when loading the overdentures at 6 weeks.

Long-term recognition memory requires protein synthesis, but little is known about the coordinate regulation of specific genes. Here, we examined expression of the plasticity-associated immediate early genes (Arc, Zif268, and Narp) in the dentate gyrus following long-term object-place recognition learning in rats. RT-PCR analysis from dentate gyrus tissue collected shortly after training did not reveal learning-specific changes in Arc mRNA expression. In situ hybridization and immunohistochemistry were therefore used to assess possible sparse effects on gene expression. Learning about objects increased the density of granule cells expressing Arc, and to a lesser extent Narp, specifically in the dorsal blade of the dentate gyrus, while Zif268 expression was elevated across both blades. Thus, object-place recognition triggers rapid, blade-specific upregulation of plasticity-associated immediate early genes. Furthermore, Western blot analysis of dentate gyrus homogenates demonstrated concomitant upregulation of three postsynaptic density proteins (Arc, PSD-95, and α-CaMKII) with key roles in long-term synaptic plasticity and long-term memory.

Placement of implants into extraction sockets targets the maintenance of peri-implant hard and soft tissue structures and the support of a natural and esthetic contour. The main advantages of immediate implant insertion in comparison with delayed implant placement protocols are as follows: a reduced treatment time, less number of sessions, and, thus, the less invasive procedure. This study examines the clinical performance (survival rate, marginal bone levels and Pink Esthetic Score [PES]) of OsseoSpeed implants placed into extraction sockets with immediate provisionalization in the anterior maxilla after a follow-up of at least 12 months. Twenty patients received a total number of 37 OsseoSpeed implants which were immediately inserted into extraction sockets with or without facial bone deficiencies of various dimensions. A flapless procedure was applied, and the implants were immediately provisionalized with temporary crowns without occlusal contacts. Facial gaps between implant surface and facial bone or the previous contour of the alveolar process were grafted with autogenous bone chips. Implants in diameters 3.5, 4.0, 4.5, and 5.0 with lengths of 11-17 mm were used in the study. During the course of the study, interproximal marginal bone levels, the thickness of the facial bony wall, implant success rate according to the criteria established by Buser, and the PES were assessed per implant. One patient with three implants did not continue the study after prosthesis delivery, the remaining 34 implants were still in function at the final follow-up (survival rate: 100%). The mean follow-up period was 27 months (range, 12-40 months). Marginal bone height at the level of the implant shoulder averaged -0.1 ± 0.55 mm (range, -1.25 to 1.47 mm) at the final follow-up. The mean PES ratings were 11.3 ± 1.8 (range, 6-14) at the final follow-up. In 78% of the patients, the PES was preserved or even improved. Success rates, marginal bone levels, and esthetic results suggest

To compare the immediate implant success rates between sites with chronic apical lesions and healthy sites in the same patients 1 year postdelayed loading. One hundred sixty-eight immediate implants were placed in sixty patients at upper incisor, canine, and premolar sites. A split-mouth design was used, placing a minimum of two implants, one in a fresh socket associated with chronic periapical disease, the average lesion size was larger than 4 mm and less than 8 mm (test group), and the other(s) in a healthy fresh socket (control group). Implant survival rate at 1 year postloading delayed was compared between the groups. The implant survival rate was 98.2% for the total sample (n = 168); out of the three implants lost, two were from the test group, and one was from the control group (in the same patient as one of the former). Among the surviving implants, five were also considered failures due to excessive bone loss (n = 3) and also because of the recurrence of the periapical lesions (n = 2). Survival rates were significantly lower in the test than control sites at 12 months postloading. Implant survival rates were significantly lower after the immediate implantation in postextraction sockets associated with chronic periapical disease (90.8%) than in healthy postextraction sockets (98.1%). © 2015 Wiley Periodicals, Inc.

Purpose: The aim of present investigation was to evaluate marginal bone level after 5-year follow-up of implants placed in healed ridges and fresh extraction sockets in maxilla with immediate loading protocol. Materials and Methods: Thirty-six patients in need of a single-tooth replacement in the anterior maxilla received 42 Astra Tech implants (Astra Tech Implant system™, Dentsply Implants, Mölndal, Sweden). Implants were placed either in healed ridges (group I) or immediately into fresh extraction sockets (group II). Implants were restored and placed into functional loading immediately by using a prefabricated abutment. Marginal bone level relative to the implant reference point was recorded at implant placement, crown cementation, 12, 36, and 60 months following loading using intra-oral radiographs. Measurements were made on the mesial and distal sides of each implant. Results: Overall, two implants were lost from the group II, before final crown cementation: they were excluded from the study. The mean change in marginal bone loss (MBL) after implant placement was 0.26 ± 0.161 mm for 1 year, and 0.26 ± 0.171 mm for 3 years, and 0.21 ± 0.185 mm for 5 years in extraction sockets and was 0.26 ± 0.176 mm for 1 year and 0.21 ± 0.175 mm for 3 years, and 0.19 ± 0.172 mm for 5 years in healed ridges group. Significant reduction of marginal bone was more pronounced in implants inserted in healed ridges (P < 0.041) compared to fresh surgical extraction sockets (P < 0.540). Significant MBL was observed on the mesial side of the implant after cementation of the provisional (P < 0.007) and after 12 months (P < 0.034) compared to the distal side which remained stable for 3 and 5 years observation period. Conclusions: Within the limitations of this study, responses of local bone to immediately loaded implants placed either in extraction sockets or healed ridges were similar.

Aims. This study evaluated the effects of L-PRF presence and implant surface texture on bone healing around immediately placed implants. Methods. The first mandibular molars of 8 beagle dogs were bilaterally extracted, and implants (Blossom™, Intra-Lock International, Boca Raton, FL) were placed in the mesial or distal extraction sockets in an interpolated fashion per animal. Two implant surfaces were distributed per sockets: (1) dual acid-etched (DAE, micrometer scale textured) and (2) micrometer/nanometer scale textured (Ossean™ surface). L-PRF (Intraspin system, Intra-Lock International) was placed in a split-mouth design to fill the macrogap between implant and socket walls on one side of the mandible. The contralateral side received implants without L-PRF. A mixed-model ANOVA (at α = 0.05) evaluated the effect of implant surface, presence of L-PRF, and socket position (mesial or distal), individually or in combination on bone area fraction occupancy (BAFO). Results. BAFO values were significantly higher for the Ossean relative to the DAE surface on the larger mesial socket. The presence of L-PRF resulted in higher BAFO. The Ossean surface and L-PRF presence resulted in significantly higher BAFO. Conclusion. L-PRF and the micro-/nanometer scale textured surface resulted in increased bone formation around immediately placed implants. PMID:28042577

The aim of the present report was to describe the use of Botulinum toxin type A as preoperative treatment for immediately loaded dental implants placed in fresh extraction sockets for full-arch restoration of patients with bruxism. Patients with bruxism who were scheduled to receive immediately loaded full-arch implant supported fixed restorations were included in this retrospective clinical report. To reduce the occlusal forces applied in patients with bruxism, Botulinum toxin type A was introduced prior to the implant placement procedure. Patients were followed and implant survival as well as peri-implant bone level was assessed in each periodic follow-up visit. Adverse effects were also recorded. A control group with no use of Botulinum toxin was evaluated as well. A total of 26 patients (13 test and 13 control), with bruxism, aged 59.15 ± 11.43 years on average were included in this retrospective report and received immediately loaded dental implants placed in fresh extraction sockets for full-arch restoration. The test group treatment preceded by Botulinum toxin type A injection. Maxillary arches were supported by 8 to 10 implants while the mandibular arch was supported by 6 implants. All surgeries went uneventfully and no adverse effects were observed. The average follow-up time was 32.5 ± 10.4 months (range, 18-51). In the test group, no implant failures were recorded. One patient presented with 1 to 2 mm bone loss around 4 of the implants; the other implants presented with stable bone level. In the control group 1 patient lost 2 implants and another demonstrated 2 mm bone loss around 3 of the implants. The preoperative use of Botulinum toxin in patients with bruxism undergoing full-arch rehabilitation using immediately loaded dental implants placed in fresh extraction sockets seems to be a technique that deserves attention. Further long-term, large-scale randomized clinical trials will help to determine the additional benefit of this suggested

Sense of Place, Fast and Slow: The Potential Contributions of Affordance Theory to Sense of Place.

2017-01-01

Over the past 40 years, the sense of place concept has been well-established across a range of applications and settings; however, most theoretical developments have "privileged the slow." Evidence suggests that place attachments and place meanings are slow to evolve, sometimes not matching material or social reality (lag effects), and also tending to inhibit change. Here, we present some key blind spots in sense of place scholarship and then suggest how a reconsideration of sense of place as "fast" and "slow" could fill them. By this, we mean how direct and immediate perception-action processes presented in affordance theory (resulting in immediately perceived place meanings) can complement slower forms of social construction presented in sense of place scholarship. Key blind spots are that sense of place scholarship: (1) rarely accounts for sensory or immediately perceived meanings; (2) pays little attention to how place meanings are the joint product of attributes of environmental features and the attributes of the individual; and (3) assumes that the relationship between place attachment and behavior is linear and not constituted in dynamic relations among mind, culture, and environment. We show how these blind spots can begin to be addressed by reviewing key insights from affordance theory, and through the presentation of applied examples. We discuss future empirical research directions in terms of: (1) how sense of place is both perceived and socially constructed; (2) whether perceived and socially constructed dimensions of place can relate to one another when perceived meanings become unsituated; and (3) how place attachment may change over different stages of the life course based upon dynamic relationships between processes of perception-action and social construction. We conclude with insights into how processes of perception-action and social construction could be included in the design and management of urban landscapes.

SUMMARY Purpose This study aims to evaluate differences in implant stability between post-extractive implants vs immediately placed post-extractive implants by resonance frequency analysis (RFA). Materials and methods Patients were grouped into two different categories. In Group A 10 patients had an immediate post-extractive implant, then a provisional, acrylic resin crown was placed (immediate loading). In Group B (control group) 10 patients only had an immediate post-extractive implant. Both upper and lower premolars were chosen as post-extractive sites. Implant Stability Quotient (ISQ) was measured thanks to RFA measurements (Osstell®). Five intervals were considered: immediately after surgery (T0) and every four weeks, until five months after implant placement (T1, T2, T3, T4,T5). A statistical analysis by means of Student’s T-test (significance set at p<0.05) for independent sample was carried out in order to compare Groups A and B. Results The ISQ value between the two groups showed a statistically significant difference (p<0.02) at T1. No statistically significant difference in ISQ was assessed at T0, T2, T3, T4 and T5. Conclusions After clinical assessment it is possible to confirm that provisional and immediate prosthetic surgery in post-extraction sites with cone-shaped implants, platform-switching abutment and bioactive surface can facilitate osseointegration, reducing healing time.

2013-01-01

Objetives: The development of treated implant surfaces, added to the increase of the aesthetic requirements by the patients has led to a change in the treatment protocols as well as the development of techniques such as the one-fase implants and the immediate prosthetic loading. One of the usual contraindications of the implant treatment is the presence of periapical disease associated to the tooth to be replaced. The aim of this paper is to review the published literature on immediate implant placement in extraction sockets of teeth with periapical pathology, considering the level of scientific evidence, and following the principles of medicine and evidence-based Dentistry. Material and Methods: A search of articles published between 1982 and 2012 was conducted. The search terms immediate, dental implant, extraction, infected, periapical pathology were used. Search was limited to studies in animals and humans, published in english language. Results: 16 articles were selected from a total of 438, which were stratified according to their level of scientific evidence using the SORT criteria (Strength of Recommendation Taxonomy). Studies in both animals and humans presented high rates of implant survival, but human studies are limited to a small number of cases. Discussion and Conclusions: There is a limited evidence regarding implant placement immediately to the extraction of teeth affected by chronic periapical pathology. Following analysis of the articles, and in function of their scientific quality, a type B recommendation is given in favor of the immediate implant placement in fresh sockets associated to periapical infectious processes. Key words:Immediate implant, periapical pathology. PMID:23722139

To compare immediate versus early non-occlusal loading of dental implants placed flapless in a 3-year, parallel group, randomized clinical trial. The study was conducted in a private dental clinic between July 2005 and July 2010. Patients 18 years or older were randomized to receive implants for fixed partial dentures in cases of partial edentulism. The test group was represented by immediate non-occlusal implant loading, whereas the control group was represented by early non-occlusal implant loading. The outcome variables were implant failure, complications and radiographic bone level at implant sites 3 years after loading, measured from the implant-abutment junction to the most coronal point of bone-to-implant contact. Randomization was computer-generated with allocation concealment by opaque sequentially numbered sealed envelopes, and the measurer was blinded to group assignment. Sixty patients were randomized: 30 to the immediately loaded group and 30 to the early loaded group. Four patients dropped out; however, the data of all patients were included in the analysis. No implant failure occurred. Two complications occurred in the control group and one in the test group. The mean bone level at 3 years was 1.91 mm for test group and 1.59 mm for control group. The adjusted difference in bone level was 0.26 mm (CI 95% -0.08 to 0.59, p = 0.1232). The null hypothesis of no difference in failure rates, complications and bone level between implants that were loaded immediately or early at 3 years cannot be rejected in this randomized clinical trial. © 2011 John Wiley & Sons A/S.

Does olfactory specific satiety take place in a natural setting?

Fernandez, P; Bensafi, M; Rouby, C; Giboreau, A

2013-01-01

Olfactory-specific satiety (OSS) is characterized by a specific decrease in the odor pleasantness of a food eaten to satiety or smelled without ingestion. The usual protocol for studying OSS takes place in laboratory, a setting rather removed from the real world. Here, we set out to examine OSS in a natural setting: during a meal in a restaurant. We hypothesized that an aroma contained in a food that is eaten at the beginning of a meal decreases the pleasantness of the flavor of a food with the same aroma eaten at the end of the meal. In the first experiment (Experiment 1), a test group received an appetizer flavored with a test aroma (anise) at the beginning of the meal. After the main dish, they received a dessert flavored with the same aroma. A control group received the same aromatized dessert, but after a non-aromatized appetizer. This experiment was replicated (Experiment 2) using verbena as the test aroma. For both experiments, results revealed that aroma pleasantness, but not intensity or familiarity, significantly decreased in the test groups vs. the control groups. These findings extend the concept of OSS to a realistic eating context. Copyright © 2012 Elsevier Ltd. All rights reserved.

The purpose of this study was to examine by proton spectroscopy for any difference in cerebral metabolites in patients taking part in the Concorde study (comparing the efficacy of immediate versus deferred treatment with zidovudine on asymptomatic HIV infected individuals). Forty seven HIV positive male patients [29 immediate, 18 deferred zidovudine] were examined in the last 9 months of the therapeutic trial. Magnetic resonance imaging and proton spectroscopy were performed at 1.5 Tesla using a single voxel placed in the parieto-occipital white matter. No significant difference was found in metabolite ratios comparing immediate versus deferred zidovudine (NA/NA+Cho+Cr 0.52 vs. 0.52). High quality spectra were acquired in relatively large numbers of patients and logistically spectroscopy may be applied to clinical therapeutic studies.

Bone preservation is an essential issue in the context of last teeth extraction and complete edentulism. The intended treatment, whether a complete denture or an implant placement, is facilitated with a voluminous residual ridge. Bone resorption after multiple extractions has not been as well studied as the bone resorption that occurs after the extraction of a single tooth. Recent advances in bone substitute materials have revived this issue. The purpose of this study is to evaluate the interest in using bone substitute material to fill the socket after last teeth extraction in a maxillary immediate complete denture procedure compared with the conventional protocol without socket filling. A randomized, controlled, clinical trial was designed. The 34 participants eligible for maxillary immediate complete denture were divided into two groups. Complete dentures were prepared despite persistence of the last anterior teeth. The control group received a conventional treatment including denture placement immediately after extractions. In the experimental group, in addition to the immediate denture placement, a xenograft bone-substitute material (Bio-Oss Collagen®) was placed in the fresh sockets. The primary outcome of the study is to compare mean bone ridge height loss 1 year after maxillary immediate complete denture placement, with or without bone-substitute material, in incisor and canine sockets. The secondary outcomes are to compare the average bone ridge height and width loss for each extraction site. An original quantitative evaluation method using cone beam computed tomography was designed for reproducible measurements, with a radio-opaque denture duplicate. Two independent operators perform the radiologic measurements. The immediate complete denture technique limits bone resorption in multiple extraction situations and thus allows better denture retention and better options for implant placement.

Background. Hydrophilic and moderately rough implant surfaces have been proposed to enhance the osseointegration response. Aim. The aim of this study was to compare early changes of stability for two implants with identical macrodesign but with different surface topographies. Materials and Methods. In 11 patients, a total of 22 implants (11 bimodal (minimally rough, control) and 11 proactive (moderately rough and hydrophilic, test), Neoss Ltd., Harrogate, UK) were immediately placed into fresh extraction sockets and immediately loaded. The peak insertion torque (IT) was measured in Ncm at placement. Resonance Frequency Analysis (RFA) measurements were made at baseline and 2, 4, 6, and 12 weeks after surgery. Results. The two implant types showed similar IT and RFA values at placement (NS). A dip of RFA values after 2 weeks followed by an increase was observed, where the test implant showed a less pronounced decrease and a more rapid recovery than the control implant. The test implants were significantly more stable than the control ones after 12 weeks. Conclusions. The results from the present study indicated that the hydrophilic and rougher test implant was more resistant to immediate loading and showed a significantly higher stability than the smoother control implant after 12 weeks.

In many areas throughout America, thousands of industrial and military facilities and agricultural operations put large numbers of people at risk of serious injury or death due to accidental chemical releases, explosions, fires, and grossly inadequate occupational exposure standards. While some companies are moving toward "greener" production, many others do the minimum required by government agencies. As evidenced by the thousands of permit violations and accidental releases of hazardous chemicals, this means that facilities across the country consistently fail to meet regulations, incorporating the cost of fines and penalties into the cost of doing business and passing that cost on to consumers. Workers at such facilities and residents of the surrounding communities cannot wait for the eventual implementation and enforcement of federal environmental laws or adequate testing of the effect chemicals may have on the human population. Immediate action is needed to protect communities and workers at risk from chemical exposures that can compromise their health.

Ever since its introduction in 1977, a minimum of few months of period is required for osseointegration to take place after dental implant surgery. With the passage of time and advancements in the fields of dental implant, this healing period is getting smaller and smaller. Immediate loading of dental implants is becoming a very popular procedure in the recent time. Hence, we retrospectively analyzed the various risk factors for the failure of delayed and immediate loaded dental implants. In the present study, retrospective analysis of all the patients was done who underwent dental implant surgeries either by immediate loading procedure or by delayed loading procedures. All the patients were divided broadly into two groups with one group containing patients in which delayed loaded dental implants were placed while other consisted of patients in whom immediate loaded dental implants were placed. All the patients in whom follow-up records were missing and who had past medical history of any systemic diseases were excluded from the present study. Evaluation of associated possible risk factors was done by classifying the predictable factors as primary and secondary factors. All the results were analyzed by Statistical Package for the Social Sciences (SPSS) software. Kaplan-Meier survival analyses and chi-square test were used for assessment of level of significance. In delayed and immediate group of dental implants, mean age of the patients was 54.2 and 54.8 years respectively. Statistically significant results were obtained while comparing the clinical parameters of the dental implants in both the groups while demographic parameters showed nonsignificant correlation. Significant higher risk of dental implant failure is associated with immediate loaded dental implants. Tobacco smoking, shorter implant size, and other risk factors play a significant role in predicting the success and failure of dental implants. Delayed loaded dental implant placement should be preferred

Immediate/early implant function means great benefits for patients and therapists because treatment time and cost can be substantially reduced. This concept has become an accepted alternative for complete arch fixed restorations in the mandible, and clinical documentation is emerging for other indications. The purpose of this prospective clinical multicenter study was to evaluate the outcome of implants placed in incisor, canine, and premolar regions in maxillas or mandibles. Implants were loaded with provisional crowns and bridges on the same day or within a few days and were followed up for 1 year during function. Four centers treated 76 patients each in need of an implant-retained prosthesis in the anterior and premolar regions in the maxilla or mandible. A total of 116 titanium implants with machined surfaces (Brånemark System , Nobel Biocare AB, Gothenburg, Sweden) were placed: 74 in maxillas and 42 in mandibles. Eighty-seven prostheses were made, of which 63 were single crowns and 24 were bridges (supported by 53 splinted implants). Twenty-two implants in 14 patients were placed in fresh extraction sites. The goal with the preparation and insertion technique was to achieve good primary implant stability and a minimum implant insertion torque of 30 Ncm before the implant was completely seated. The occlusion was adjusted to eliminate direct contact with the provisional prostheses. After 6 months, the patients received their permanent prostheses. Sixty-seven patients were followed for 1 year. Five implants were lost in five patients, three in the maxilla and two in the mandible. Four of the lost implants were single-tooth replacements and one was splinted. The cumulative survival rate (CSR) was 95.7% for all implants after 1 year and 93.7% and 98.1% for single-tooth and splinted implants, respectively. There were no implant losses in the extraction sites. The CSR of 96% at 1 year indicates that immediate function of Brånemark System implants placed in incisor

In the maxillary arch from premolar to premolar, 26 single dental implants were inserted in fresh extraction sockets and immediately provisionalized. The bone-to-implant gap was grafted with a bovine bone mineral. After 3 months, definitive ceramic crowns were placed. At baseline and after 1 year, the soft tissue horizontal width, mesiodistal papillary level, midfacial gingival level, and pink esthetic score were evaluated. No statistical differences were found between baseline and 1 year for all parameters. Immediate single-tooth implants, with immediate restoration, are capable of maintaining the soft tissue contour and esthetics compared to the pretreatment status.

On the persistence of cocaine-induced place preferences and aversions in rats

PubMed Central

Su, Zu-In; Santoostaroam, Ashley; Wenzel, Jennifer; Ettenberg, Aaron

2013-01-01

Rationale Rats develop preferences for places associated with the immediate rewarding effects of cocaine and aversions for places paired with the drug’s delayed negative effects. The motivation to seek cocaine should therefore depend upon the relative magnitude of these two opposing effects of the drug. Objective The current study tested this notion by assessing the relative persistence of the positive and negative associations formed between environmental cues and the immediate or delayed effects of cocaine. Methods Rats were administered 1.0 mg/kg intravenous cocaine and placed into a distinctive environment either immediately or 15-min after injection, alternating daily with pairings of a second environment with saline. After 4 drug- and 4 saline-place pairings, rats were returned to their home cages for 1, 7 or 21 days after which a 15-min place preference test was conducted. In a second experiment, the effectiveness of a single reconditioning session (one drug-place and one saline-place pairing) to reactivate learned cocaine-place associations was assessed after 1- or 3-weeks of drug abstinence. Results Places associated with the immediate effects of cocaine were preferred (CPP), while places associated with the delayed effects of cocaine were avoided (CPA). The persistence of these effects differed with CPP remaining viable at 3-weeks of withdrawal while CPA was no longer present after 1-week. Reconditioning with an additional cocaine-place pairing failed to reinstate the CPA. Conclusions Cue-induced “relapse” of cocaine-seeking behavior may be fueled in part by an increased persistence of positive relative to negative associations with drug-paired stimuli. PMID:23568579

This prospective study evaluates immediately placed and immediately provisionalized implants in the esthetic zone. All implants were TiO2-blasted, fluoride-modified, grade 4 titanium, with a coronal microthread design. Bone grafting and guided bone regeneration (GBR) was performed at all sites, and screw-retained temporary restorations were delivered on the day of surgery. All of the provisional crown(s) were out of occlusal function and remained in place for at least 8 weeks prior to initiation of definitive restorative therapy. Bone maintenance (BM) was considered successful if radiographs demonstrated proximal bone levels even or coronal to the implant platform. Of the 29 implants placed, 25 (86 percent) achieved bone maintenance at least 12 months post-loading with the final restorations. This study was considered successful, with 100 percent implant survival after at least 1 year loading of the final restoration, and 100 percent of patients were satisfied with the esthetics of their implant treatment.

Background The aim of this prospective study was to report the outcome of treatment with implants inserted after tooth extraction and immediately loaded. Material and Methods Fifty-six patients with single tooth loss were treated with 116 IPX Galimplant® implants with internal connections and a sandblasted, acid-etched surface. All implants were placed after tooth extraction using a flapless approach without bone regeneration, and they were then immediately loaded with cemented acrylic prostheses. After a period of three months, definitive cemented ceramic prostheses were placed. Patients were examined throughout a total of 4 years of follow-up. Marginal bone loss and survival rates were evaluated using digital periapical radiographs, taking into account clinical variables such as age, gender, smoking, history of periodontitis, etiology of extraction, placement site, diameter, and implant length. The Mann-Whitney U and Kruskal-Wallis non-parametric tests were used to compare differences between subgroups created based on the different clinical variables identified. Results Clinical results indicate an implant survival and success rate of 97.4%. Three implants were lost. Of the 116 immediate acrylic single crowns initially placed, 113 were replaced with definitive ceramic crowns after 3 months. A total of 77.8% of implants were inserted in the maxilla, while 22.2% were inserted in the mandible. No further complications were reported after the follow-up period (4 years). The mean marginal bone loss was 0.67 mm ± 0.40 mm. No differences were found among the subgroups of study patients. Conclusions This study indicates that dental implants that are inserted after tooth extraction and immediately loaded may constitute a successful and predictable alternative implant treatment.

The esthetics and functional integrity of the periodontal tissue may be compromised by dental loss. Immediate implants became a viable option to maintain the periodontal architecture because of their anatomic compatibility with the dental socket and the possibility of eliminating local contamination. This article describes the procedure of immediate implant placement in the anterior maxilla replacing teeth with chronic periapical lesions, which were condemned due to endodontic lesions persisting after failed endodontic treatment and endodontic surgery, and discusses the relationship between the procedure and periapical lesions. Surgical removal of hopeless teeth 11, 12 and 21 was performed conservatively in such a way to preserve the anatomy and gingival esthetics. A second surgical access was gained at the apical level, allowing the debridement of the surgical chamber for elimination of the periapical lesion, visual orientation for setting of the implants and filling of the surgical chamber with xenogenous bovine bone graft. After this procedure, the bone chamber was covered with an absorbent membrane and the healing screws were positioned on the implants. Later, a provisional partial removable denture was installed and the implants were inserted after 6 months. After 3 years of rehabilitation, the implants present satisfactory functional and esthetic conditions, suggesting that immediate implant placement combined with guided bone regeneration may be indicated for replacing teeth lost due to chronic periapical lesions with endodontic failure history in the anterior maxilla.

However, initiatives aimed at implementing these technologies are complicated by the fact that multiple stakeholder groups are involved. Goals and motives of stakeholders may not always be transparent or aligned, yet research on convergent and divergent positions of stakeholders is scarce. To provide insight into the positions of stakeholder groups involved in the implementation of technology for aging in place by answering the following questions: What kind of technology do stakeholders see as relevant? What do stakeholders aim to achieve by implementing technology? What is needed to achieve successful implementations? Mono-disciplinary focus groups were conducted with participants (n=29) representing five groups of stakeholders: older adults (6/29, 21%), care professionals (7/29, 24%), managers within home care or social work organizations (5/29, 17%), technology designers and suppliers (6/29, 21%), and policy makers (5/29, 17%).

Background Skeletal anchorage using dental implants, miniplates, miniscrews and microscrews provides an absolute anchorage for tooth movement. Miniscrew and microscrew implants have many benefits such as ease of placement and removal and immediate orthodontic force application. Methods Fifteen subjects in the permanent dentition with an overjet ≥6 mm received treatment with the 0.018-inch pre-adjusted edgewise appliance system (Roth prescription) and extraction of all first premolars. Titanium orthodontic implants were placed in both the upper quadrants and were immediately loaded with elastic chain from the implant head to the sectional arch wire. Result The overall success rate of immediate loaded titanium orthodontic micro implants (OMI) in the present study was 83.33%, with a mean chairside time of 15.33 min of placing two implants in each patient. Peri-implant inflammation was the only complication observed. Most failures were in the initial part of the study. There was no significant difference in the success rate of implants based on sex, side of placement (right or left) and type of malocclusion. Conclusion The OMIs used in the present study proved to be effective and well tolerated in producing immediate orthodontic anchorage for the retraction. PMID:25859080

Aim: To determine whether changes in orthoptic status take place during withdrawal from heroin and/or methadone. Method: A prospective study of patients, using a repeated measures design, attending a 5 day naltrexone compressed opiate detoxification programme. Results: 83 patients were seen before detoxification (mean age 27.1 (SD 4.6) years) and 69 after detoxification. The horizontal angle of deviation became less exo/more eso at distance (p<0.001) but no significant change was found at near (p = 0.069). Stereoacuity, visual acuity, and convergence were found to be reduced in the immediate post-detoxification period. Prism fusion range, refractive error, subjective accommodation, and objective accommodation at 33 cm did not reduce but a small decrease was found in objective accommodation at 20 cm. Conclusions: The eso trend found in these patients may be responsible for the development of acute concomitant esotropia in some patients undergoing heroin detoxification. However, the mechanism for this trend does not appear to be caused by divergence insufficiency or sixth nerve palsy. PMID:15317713

Unconscious-thought effects take place off-line, not on-line.

PubMed

Strick, Madelijn; Dijksterhuis, Ap; van Baaren, Rick B

2010-04-01

The unconscious-thought effect refers to an improvement in decision making following distraction from the decision context for a period of time. The dominant explanation for this effect is that unconscious processes continue to deal with the problem during the distraction period. Recently, however, some researchers have proposed that unconscious thinkers may be merely recalling a judgment that was formed on-line (i.e., during information acquisition). We present two experiments that rule out the latter interpretation. In the unconscious-thought condition of the first experiment, participants who reported making their decision after unconscious thought made better decisions than those who reported making their decision on-line. In the second experiment, all participants judged the choice alternatives both on-line and off-line. On-line judgments were predictive of off-line judgments only in the immediate-decision condition, but not in the conscious- and unconscious-thought conditions. These results demonstrate that a period of unconscious thought does improve judgments that were formed earlier on-line.

From sense of place to visualization of place: examining people-place relationships for insight on developing geovisualizations.

PubMed

Newell, Robert; Canessa, Rosaline

2018-02-01

Effective resource planning incorporates people-place relationships, allowing these efforts to be inclusive of the different local beliefs, interests, activities and needs. 'Geovisualizations' can serve as potentially powerful tools for facilitating 'place-conscious' resource planning, as they can be developed with high degrees of realism and accuracy, allowing people to recognize and relate to them as 'real places'. However, little research has been done on this potential, and the place-based applications of these visual tools are poorly understood. This study takes steps toward addressing this gap by exploring the relationship between sense of place and 'visualization of place'. Residents of the Capital Regional District of BC, Canada, were surveyed about their relationship with local coastal places, concerns for the coast, and how they mentally visualize these places. Factor analysis identified four sense of place dimensions - nature protection values, community and economic well-being values, place identity and place dependence, and four coastal concerns dimensions - ecological, private opportunities, public space and boating impacts. Visualization data were coded and treated as dependent variables in a series of logistic regressions that used sense of place and coastal concerns dimensions as predictors. Results indicated that different aspects of sense of place and (to a lesser degree) concerns for places influence the types of elements people include in their mental visualization of place. In addition, sense of place influenced the position and perspective people assume in these visualizations. These findings suggest that key visual elements and perspectives speak to different place relationships, which has implications for developing and using geovisualizations in terms of what elements should be included in tools and (if appropriate) depicted as affected by potential management or development scenarios.

Influence of immediate loading on provisional restoration in dental implant stability

NASA Astrophysics Data System (ADS)

Ikbal, M.; Odang, R. W.; Indrasari, M.; Dewi, R. S.

2017-08-01

The success of dental implant treatment is determined by the primary stability at placement. One factor that could influence this stability is occlusal loading through provisional restoration. Two types of loading protocols are usually used: immediate and delayed loading. However, some controversies remain about the influence of occlusal loading on implant stability. Therefore, the influence of immediate loading on implant stability must be studied. An animal study was conducted by placing nine dental implants in the mandibular jaw of three Macaca fascicularis. Provisional restorations with various occlusal contacts (no, light, and normal contact) were placed on the implant. The implant stability was measured using the Ostell ISQ three times: immediately (baseline) and at the first and second months after implant placement. The implant stability between implants with no and normal occlusal contact as well as light and normal occlusal contact showed significant differences (p < 0.05) at the first and second months after implant placement. However, no significant increase (p > 0.05) in implant stability was seen at the baseline and the first and second months after implant placement for all occlusal contact groups. Immediate loading influenced the implant stability, and provisional restoration of implant without occlusal contact showed the highest implant stability.

The value of place

NASA Astrophysics Data System (ADS)

Dentzau, Michael W.

2014-03-01

This commentary seeks to expand the dialogue on place-based science education presented in Katie Lynn Brkich's article, where the connections fifth grade students make between their formal earth science curriculum and their lived experiences are highlighted. The disconnect between the curriculum the students are offered and their immediate environment is clear, and we are presented with examples of how they strive to make connections between the content and what they are familiar with—namely their surroundings. "Place" is identified as a term with complex meanings and interpretations, even in the scope of place-based science education, and understanding how the term is used in any given scenario is essential to understanding the implications of place-based education. Is place used as a location, locale or a sense of place? To understand "place" is to acknowledge that for the individual, it is highly situational, cultural and personal. It is just such attributes that make place-based education appealing, and potentially powerful, pedagogically on one hand, yet complex for implementation on the other. The argument is posed that place is particularly important in the context of education about the environment, which in its simplest manifestation, connects formal science curriculum to resources that are local and tangible to students. The incorporation of place in such a framework seeks to bridge the gap between formal school science subjects and students' lived experiences, yet acknowledges the tensions that can arise between accommodating place meanings and the desire to acculturate students into the language of the scientific community. The disconnect between guiding policy frameworks and the reality of the Next Generation Science Standards is addressed opening an avenue for further discussion of the importance of socio-cultural frameworks of science learning in an ever increasing era of accountability.

Advanced immediate functional loading: requirements for long-term success in modern implant dentistry.

PubMed

Romanos, Georgios E

2014-01-01

There are benefits to be derived from the use of advanced surgical protocols in conjunction with immediate functional loading using various dental implant designs and implant-abutment connections. Clinical protocols with simultaneous bone grafting, immediate implant placement, and/or sinus augmentations when a shortened treatment period is needed are included in this report, with the aim of providing understanding of the main protocol characteristics and prerequisites for long-term success in implant dentistry. This article presents three clinical cases that illustrate possibilities for advanced immediate loading using different implant designs. It demonstrates treatment of severe bone defects and the facilitation of placing implants in regenerated bone that can be immediately loaded.

Immediate extinction promotes the return of fear.

Merz, Christian J; Hamacher-Dang, Tanja C; Wolf, Oliver T

2016-05-01

Accumulating evidence indicates that immediate extinction is less effective than delayed extinction in attenuating the return of fear. This line of fear conditioning research impacts the proposed onset of psychological interventions after threatening situations. In the present study, forty healthy men were investigated in a differential fear conditioning paradigm with fear acquisition in context A, extinction in context B, followed by retrieval testing in both contexts 24h later to test fear renewal. Differently coloured lights served as conditioned stimuli (CS): two CS (CS+) were paired with an electrical stimulation that served as unconditioned stimulus, the third CS was never paired (CS-). Extinction took place immediately after fear acquisition or 24h later. One CS+ was extinguished whereas the second CS+ remained unextinguished to control for different time intervals between fear acquisition and retrieval testing. Immediate extinction led to larger skin conductance responses during fear retrieval to both the extinguished and unextinguished CS relative to the CS-, indicating a stronger return of fear compared to delayed extinction. Taken together, immediate extinction is less potent than delayed extinction and is associated with a stronger renewal effect. Thus, the time-point of psychological interventions relative to the offset of threatening situations needs to be carefully considered to prevent relapses. Copyright © 2016 Elsevier Inc.

2013-06-01

To examine the influence of bone-substitute application during implantation on the success of immediately placed and loaded dental implants. A total of 147 consecutive patients (age, 16.5-80.4 years) were provided with 696 immediately loaded implants. The mean follow-up time was 34.1 months. Of these implants, 50.4% (n=351) were immediately placed into extraction sockets. A total of 119 implants were added by simultaneous bone-substitute application (NanoBone, Artoss GmbH, Rostock Germany), whereas the other implants were placed in healed bone. Univariate and multivariate analysis was performed using IBM SPSS V.20. The overall implant success rate was 96.1%. Implants with simultaneous bone replacement had a hazard ratio of 0.877 (p=0.837); 95% CI, 0.253-3.04). Factors found to be statistically significant modifiers of success on multivariate analysis (p<0.05) included type of superstructure (p<0.001), implant-abutment connection (p<0.001), membrane use (p=0.010), and jaw (p=0.026). None of the other factors investigated were significant modifiers. The present study demonstrates high success rates for immediately loaded implants and their superstructures independent of the simultaneous application of bone substitute. The declared aim of socket preservation, the prevention avoiding bone loss, is achieved in the immediate implant placement scenario under immediate-loading conditions.

Immediate response strategy and shift to place strategy in submerged T-maze.

PubMed

Asem, Judith S A; Holland, Peter C

2013-12-01

A considerable amount of research has demonstrated that animals can use different strategies when learning about, and navigating within, their environment. Since the influential research of Packard and McGaugh (1996), it has been widely accepted that, early in learning, rats use a flexible dorsal hippocampal-dependent place strategy. As learning progresses, they switch to a less effortful and more automatic dorsolateral caudate-dependent response strategy. However, supporting literature is dominated by the use of appetitively motivated tasks, using food reward. Because motivation often plays a crucial role in guiding learning, memory, and behavior, we examined spatial learning strategies of rats in an escape-motivated submerged T-maze. In Experiment 1, we observed rapid learning and the opposite pattern as that reported in appetitively motivated tasks. Rats exhibited a response strategy early in learning before switching to a place strategy, which persisted over extensive training. In Experiment 2, we replicated Packard and McGaugh's (1996) observations, using the apparatus and procedures as in Experiment 1, but with food reward instead of water escape. Mechanisms for, and implications of, this motivational modulation of spatial learning strategy are considered.

Bell, Christopher Lincoln; Diehl, David; Bell, Brian Michael; Bell, Robert E

2011-06-01

The purpose of this study was to evaluate the success of dental implants placed immediately into extraction sites in the presence of chronic periapical pathology. The charts of 655 patients who had implants immediately placed into fresh extraction sites were reviewed for the presence or absence of periapical radiolucencies. A total of 922 implants were included. Of the 922 implants, 285 were immediately placed into sockets that had chronic periapical infections. The remaining 637 implants, without signs of periapical pathology, were used as the control group. Success of the implants was defined as successful osseointegration, successful restoration, and absence of evidence of bone loss or peri-implantitis. Other variables such as age, gender, smoking, diabetes, bisphosphonate use, lucencies of adjacent teeth, and implant stability at the time of placement were also evaluated. Of the 922 implants, 285 were placed into sockets with periapical radiolucencies. The success rate of implants placed in the study group was 97.5%, whereas the success rate of the control group was 98.7%. The difference was not found to be statistically significant. The mean follow-up was 19.75 months, with a maximum of 93 months and a minimum of 3 months. A statistically higher failure rate was found for implants placed adjacent to retained teeth with periapical pathology. The placement of implants in sockets affected by chronic periapical pathology can be considered a safe and viable treatment option. There is a risk of implant failure when placing implants adjacent to teeth with periapical radiolucencies. Copyright © 2011 American Association of Oral and Maxillofacial Surgeons.

Maló, Paulo; Nobre, Miguel de Araújo; Lopes, Armando; Ferro, Ana; Gravito, Inês

2014-01-01

To report the 5-year outcome of immediately loaded dental implants in patients with untreated periodontal disease. This prospective cohort study included 103 consecutive patients (51 females and 52 males) with an average age of 52 years (range: 22 to 80 years) who were rehabilitated with 380 implants supporting 145 prostheses in both jaws (40 single; 33 partial and 72 complete rehabilitations). The implants were inserted in patients with active and untreated periodontitis. The patients did not receive any previous periodontal treatment before implant surgery, except for an oral hygiene session immediately before the implant surgery. In maintenance (every 6 months) patients received periodontal treatment as needed. Outcome measures were: prostheses failures; implant failures; complications; and marginal bone level changes. Fifteen patients dropped out of the study (14.6%). Two patients lost two implants (FDI positions nos.12 and 42), rendering a cumulative survival rate of 97.9% and 99.4% at 5 years of followup using the patient and implant as unit of analysis, respectively. The average (standard deviation) marginal bone resorption was 0.71 mm (0.42 mm) at 5 years. Mechanical complications occurred in 14 patients, consisting of prostheses fractures (10 provisional prostheses and 4 definitive prostheses). Thirteen implants (3.9%) in 13 patients (14.8%) presented peri-implant pathology. Within the limitations of this study, it is possible to conclude that the rehabilitation of patients with untreated periodontitis using immediately loaded dental implants is feasible in the medium-term, when periodontal therapy is provided after rehabilitation and the patients are regularly maintained.

Place Cells, Grid Cells, and Memory

PubMed Central

Moser, May-Britt; Rowland, David C.; Moser, Edvard I.

2015-01-01

The hippocampal system is critical for storage and retrieval of declarative memories, including memories for locations and events that take place at those locations. Spatial memories place high demands on capacity. Memories must be distinct to be recalled without interference and encoding must be fast. Recent studies have indicated that hippocampal networks allow for fast storage of large quantities of uncorrelated spatial information. The aim of the this article is to review and discuss some of this work, taking as a starting point the discovery of multiple functionally specialized cell types of the hippocampal–entorhinal circuit, such as place, grid, and border cells. We will show that grid cells provide the hippocampus with a metric, as well as a putative mechanism for decorrelation of representations, that the formation of environment-specific place maps depends on mechanisms for long-term plasticity in the hippocampus, and that long-term spatiotemporal memory storage may depend on offline consolidation processes related to sharp-wave ripple activity in the hippocampus. The multitude of representations generated through interactions between a variety of functionally specialized cell types in the entorhinal–hippocampal circuit may be at the heart of the mechanism for declarative memory formation.

Immediate implant placement followed by an immediate restoration has proven to be a viable technique in the anterior maxillary region. This prospective study evaluated the mid-long term (2-5 years) tissue changes around immediately placed and restored implants in the anterior maxilla using flapless surgery and simultaneous hard tissue augmentation. Thirty AstraTech implants were immediately placed in 30 patients, followed by the delivery of an immediate provisional restoration on the same day. All participating 30 patients underwent the same treatment strategy that involved flapless removal of a failing maxillary anterior tooth, immediate implant placement, simultaneous augmentation with a deproteinized particulate xenograft, followed by the connection of a screw-retained provisional restoration. Radiographs and photographs were used to measure hard and soft tissue changes. Aesthetic evaluation was performed using the Pink Esthetic Score (PES). All implants remained osseointegrated during the follow up period of 2-5 years (mean 47 ± 15 months). Twelve of the thirty patients completed the 5 year follow up. Radiographic evaluation revealed average gains in bone levels of 0.18 and 0.34 mm mesially and distally, respectively. Soft tissue evaluation showed a mean tissue loss of 0.05 ± 0.64 mm and 0.16 ± 0.63 mm at the mesial and distal papillae, respectively, while mid-facial mucosal recession was 0.29 ± 0.74 mm. A significant improvement in the Pink Esthetic Scores was seen at the final follow-up (mean PES 11.50), as compared to the baseline (mean PES 10.27) (P = .001). In addition to a favorable implant success rate and peri-implant bony response, the soft tissue levels and overall aesthetics around single immediately placed and restored implants can also be maintained in the mid-long term. © 2017 Wiley Periodicals, Inc.

Beyond stereotypes of adolescent risk taking: Placing the adolescent brain in developmental context☆

PubMed Central

Romer, Daniel; Reyna, Valerie F.; Satterthwaite, Theodore D.

2017-01-01

Recent neuroscience models of adolescent brain development attribute the morbidity and mortality of this period to structural and functional imbalances between more fully developed limbic regions that subserve reward and emotion as opposed to those that enable cognitive control. We challenge this interpretation of adolescent development by distinguishing risk-taking that peaks during adolescence (sensation seeking and impulsive action) from risk taking that declines monotonically from childhood to adulthood (impulsive choice and other decisions under known risk). Sensation seeking is primarily motivated by exploration of the environment under ambiguous risk contexts, while impulsive action, which is likely to be maladaptive, is more characteristic of a subset of youth with weak control over limbic motivation. Risk taking that declines monotonically from childhood to adulthood occurs primarily under conditions of known risks and reflects increases in executive function as well as aversion to risk based on increases in gist-based reasoning. We propose an alternative Lifespan Wisdom Model that highlights the importance of experience gained through exploration during adolescence. We propose, therefore, that brain models that recognize the adaptive roles that cognition and experience play during adolescence provide a more complete and helpful picture of this period of development.

Chunk formation in immediate memory and how it relates to data compression.

PubMed

Chekaf, Mustapha; Cowan, Nelson; Mathy, Fabien

2016-10-01

This paper attempts to evaluate the capacity of immediate memory to cope with new situations in relation to the compressibility of information likely to allow the formation of chunks. We constructed a task in which untrained participants had to immediately recall sequences of stimuli with possible associations between them. Compressibility of information was used to measure the chunkability of each sequence on a single trial. Compressibility refers to the recoding of information in a more compact representation. Although compressibility has almost exclusively been used to study long-term memory, our theory suggests that a compression process relying on redundancies within the structure of the list materials can occur very rapidly in immediate memory. The results indicated a span of about three items when the list had no structure, but increased linearly as structure was added. The amount of information retained in immediate memory was maximal for the most compressible sequences, particularly when information was ordered in a way that facilitated the compression process. We discuss the role of immediate memory in the rapid formation of chunks made up of new associations that did not already exist in long-term memory, and we conclude that immediate memory is the starting place for the reorganization of information.

Note taking, review, memory, and comprehension.

Bohay, Mark; Blakely, Daniel P; Tamplin, Andrea K; Radvansky, Gabriel A

2011-01-01

In previous work assessing memory at various levels of representation, namely the surface form, textbase, and situation model levels, participants read texts but were otherwise not actively engaged with the texts. The current study tested the influence of active engagement with the material via note taking, along with the opportunity to review such notes, and the modality of presentation (text vs. spoken). The influence of these manipulations was assessed both immediately and 1 week later. In Experiment 1 participants read a text, whereas in Experiment 2 participants watched a video recording of the material being read as a lecture. For each experiment the opportunity to take notes was manipulated within participants, and the opportunity to review these notes before the test was manipulated between participants. Note taking improved performance at the situation model level in both experiments, although there was also some suggestion of benefit for the surface form. Thus, active engagement with material, such as note taking, appears to have the greatest benefit at the deeper levels of understanding.

Immediate behavioural responses to earthquakes in Christchurch, New Zealand, and Hitachi, Japan.

This study examines people's immediate responses to earthquakes in Christchurch, New Zealand, and Hitachi, Japan. Data collected from 257 respondents in Christchurch and 332 respondents in Hitachi revealed notable similarities between the two cities in people's emotional reactions, risk perceptions, and immediate protective actions during the events. Respondents' physical, household, and social contexts were quite similar, but Hitachi residents reported somewhat higher levels of emotional reaction and risk perception than did Christchurch residents. Contrary to the recommendations of emergency officials, the most frequent response of residents in both cities was to freeze. Christchurch residents were more likely than Hitachi residents to drop to the ground and take cover, whereas Hitachi residents were more likely than Christchurch residents to evacuate immediately the building in which they were situated. There were relatively small correlations between immediate behavioural responses and demographic characteristics, earthquake experience, and physical, social, or household context. © 2016 The Author(s).

Single-blind randomized clinical trial to evaluate clinical and radiological outcomes after one year of immediate versus delayed implant placement supporting full-arch prostheses

PubMed Central

Pellicer-Chover, Hilario; Peñarrocha-Oltra, David; Bagán, Leticia; Fichy-Fernandez, Antonio J.; Canullo, Luigi

2014-01-01

Purpose: To evaluate and compare peri-implant health, marginal bone loss and success of immediate and delayed implant placement for rehabilitation with full-arch fixed prostheses. Material and Methods: The present study was a prospective, randomized, single-blind, clinical preliminary trial. Patients were randomized into two treatment groups. In Group A implants were placed immediately post-extraction and in Group B six months after extraction. The following control time-points were established: one week, six months and twelve months after loading. Measurements were taken of peri-implant crevicular fluid volume, plaque index, gingival retraction, keratinized mucosa, probing depth, modified gingival index and presence of mucositis. Implant success rates were evaluated for the two groups. The study sample included fifteen patients (nine women and six men) with a mean average age of 63.7 years. One hundred and forty-four implants were placed: 76 placed in healed sites and 68 placed immediately. Results: At the moment of prosthetic loading, keratinized mucosa width and probing depth were higher in immediate implants than delayed implants, with statistically significant differences. However, after six and twelve months, differences between groups had disappeared. Bone loss was 0.54 ± 0.39 mm for immediate implants and 0.66 ± 0.25 mm for delayed implants (p=0.201). No implants failed in either group. Conclusions: The present study with a short follow-up and a small sample yielded no statistically significant differences in implant success and peri-implant marginal bone loss between immediate and delayed implants with fixed full-arch prostheses. Peri-implant health showed no statistically significant differences for any of the studied parameters (crevicular fluid volume, plaque index, gingival retraction, keratinized mucosa, probing depth, modified gingival index and presence of mucositis) at the twelve-month follow-up.

2016-01-01

The aim of this study was to evaluate the effectiveness of techniques for soft tissue augmentation in the placement of immediate implants with and without provisionalization and to assess the quality of the reports in the literature. Randomized clinical trials, prospective clinical trials, and case series were included in this review. Clinical questions were formulated and organised according to the PICOS strategy. An electronic search was performed in PubMed, Cochrane Central Register of Controlled Trials, Scopus, and ISI Web up until June 2016. Interexaminer agreement on eligibility (k = 0.842; p = 0.103) and quality (k = 0.933; p < 0.001) was high. Methodological approaches were assessed using criteria based on design related forms designed by the Dutch Cochrane Collaboration. Finally, 14 papers were identified. In two studies, the implant survival was 90%; for the rest of the studies it was 100%. All studies reported favourable aesthetic, biological, and radiographic outcomes. Surgical and biomechanical complications of this technique were not relevant. This technique effectively compensates for the expected loss of volume of the oral soft tissues and maintains high success rates with good aesthetic results over time. PMID:27517046

Exposure to air pollution and its sources is increasingly viewed as a psychosocial stress, however its nature is not understood. This article explores the role of the concept of place on risk perception and community stress within data collected from eight focus groups in Philadelphia, USA. Discussions focused on air pollution, a nearby oil refinery, health, and a proposal for air monitoring. We present a framework of place-based elements of risk perception that includes place identity, stigma and social control. Our findings indicate that air pollution contributes to physical and psychosocial conditions that act as community-level social stressors. Findings also suggest that programs which seek to change behaviors and gather or spread information on issues such as pollution and other environmental concerns will be challenged unless they directly address: 1) the public’s identification with a place or industry, 2) immediate environmental stressors such as abandonment, waste and odors, and 3) public perceptions of lack of social control and fear of displacement.

Objective: To evaluate the primary clinical outcomes of immediate provisionalization with a monolithic crown utilizing a novel chairside computer aided design and computer aided manufacture (CAD/CAM) workflow for single tooth immediate implant placement. Methods: This pilot study was a prospective within-subjects design. Thirteen consecutive patients were included and diagnosed with untreatable single incisor or premolar with fine general and local anatomical conditions. The trial was conducted at Department of Implantology, Peking University School and Hospital of Stomatology, Beijing, between January 2016 and June 2016. The teeth were extracted atraumatically and implants were immediately placed in the fresh sockets. Two screw-retained interim crowns were fabricated for the same site utilizing different workflows, a monolithic lithium disilicate (LS2) crown produced by CEREC (Sirona, Germany) chairside CAD/CAM system (CER group) and a manually fabricated resin crown utilizing conventional workflow (CONV group) respectively. The patients were blinded to the group allocation of the two interim crowns. After the clinical try-in for both crowns in a randomized sequence, the patients ' level of satisfaction was assessed with a virtual analogue scale (VAS) questionnaire. The restorations chosen by patients themselves were seated in the implants by one experienced prosthodontist. The accuracy, aesthetic effect and clinical time consumption of both groups were compared. Statistical analyses were performed with the Wilcoxon signed rank test. Results: All patients were treated with atraumatic tooth extraction, immediate implant placement using flapless surgery and immediate provisionalization in a single visit. The interim crowns of both groups could be fitted with or without slight adjustments. For each patient, the interim crown of CER group was chosen to be seated with a relatively higher VAS result. The white esthetic score (WES) results demonstrated no statistically

Immediate Implant Placement in Single-Tooth Molar Extraction Sockets: A 1- to 6-Year Retrospective Clinical Study.

PubMed

Amato, Francesco; Polara, Giorgio

The aim of this study was to investigate the survival rate of implants immediately placed in fresh extraction sockets of molars in the maxilla and mandible with a single-stage procedure. A total of 102 patients were treated, and 107 implants (53 in the maxilla and 54 in the mandible) were placed in a fresh molar extraction socket and connected to a healing abutment. After a mean follow-up of 3 years (range: 1 to 6 years) 1 implant failed, for a cumulative success rate of 99.06% (98.11% for the mandible and 100% for the maxilla). The results of this study support placement of an implant immediately after the extraction of a molar, applying a single-stage procedure.

Agmatine attenuates methamphetamine-induced conditioned place preference in rats.

PubMed

Thorn, David A; Winter, Jerrold C; Li, Jun-Xu

2012-04-05

The polyamine agmatine modulates a variety of behavioral effects including the abuse-related effects of opioids and has been proposed as a potential medication candidate for the treatment of opioid abuse. However, little is known of the effects of agmatine on the abuse-related effects of other drugs of abuse. This study examined the effects of agmatine on the rewarding effects of methamphetamine in rats using a conditioned place preference paradigm. Methamphetamine (0.1-1.0mg/kg) dose-dependently increased the time spent in methamphetamine-paired side (place preference). Agmatine, at doses that did not produce place preference or aversion (10-32mg/kg), significantly decreased the development of methamphetamine-induced place preference when agmatine was administered in combination with methamphetamine during place conditioning. Agmatine also significantly decreased the expression of methamphetamine-induced place preference when an acute injection of agmatine was given immediately before test session. These doses of agmatine do not alter the motor activity in rats, suggesting that the observed attenuation of methamphetamine-induced place preference was not due to general behavioral disruption. Together, these data suggests that agmatine attenuates the rewarding effects of methamphetamine and may be able to modulate the abuse liability of methamphetamine. Copyright © 2012 Elsevier B.V.

2014-11-01

The primary aim of this study was to compare the bone reaction around immediate-loaded non-splinted single implants vs. delayed loaded non-splinted single implants placed in healed ridges in the posterior mandible. Six adult Macaca Fascicularis monkeys were used in this study. The first and second premolars and the first molar were extracted in both sides of the mandible. After 3 months of healing, four implants (Replace Select Tapered; Nobel Biocare, Gothenburg, Sweden) with a moderately rough surface (TiUnite, Nobel Biocare) were placed in the edentulous areas of each monkey, two in each side. The implants had a length of 10 mm and a diameter of 3.5 mm. Four groups of varying time and occlusal loading aspects were created: (i) control group: implant placed non-loaded for 3 months; (ii) immediate loaded: implant placed and loaded immediately for 3 months; (iii) immediate loaded: implant placed and loaded immediately for 6 months; and (iv) delayed loaded: implant placed submerged for 3 months and then loaded for 3 months. At the loaded implants, after a second stage surgery, a composite crown was made directly on an abutment mounted on the implant reinsuring simultaneous occlusal contact on the implant crown and the neighboring teeth. After euthanization of the animals, histologic specimens were quantified in the light microscope. All implants were clinically, radiographically, and histologically osseointegrated at the time of euthanization and with only mild signs of inflammation in the peri-implant mucosa. The histologic marginal bone level was located on average 1.14-1.74 mm apical to the margin of the implants in the various groups. The average bone-to-implant contact (BIC) varied between 55% and 65% and the average bone density (i.e., the proportion of mineralized bone tissue from the implant surface and to a distance of 1 mm lateral to the implant) varied between 30.6% and 34.2%. No statistical significant differences between groups were observed in

Multidose drug dispensing (MDD) is used to help patients take their medicines appropriately. Little is known about drug regimen changes within these MDD systems and how they are effectuated by the community pharmacist. Manual immediate adjustments of the MDD system could introduce dispensing errors. MDD guidelines therefore recommend to effectuate drug regimen changes at the start of a new MDD system. The aim of this study was to investigate the frequency, type, procedure followed, immediate necessity, and time taken to make MDD adjustments. This was a cross-sectional study in eight community pharmacies in the Netherlands. All adjustments to MDD systems were systematically documented for 3 weeks by the community pharmacist. Overall, 261 MDD adjustments involving 364 drug changes were documented for 250 patients: 127 (35%) drug changes involved the addition of a new drug, 124 (34%) a change in dosage, and 95 (26%) drug discontinuation. Of the MDD adjustments, 135 (52%) were effectuated immediately: 81 (31%) by adjusting the MDD system manually, 49 (19%) by temporarily dispensing the drug separately from the MDD system, and 5 (2%) by ordering a new MDD system. Pharmacists considered that 36 (27%) of the immediate MDD adjustments could have been deferred until the next MDD system was produced. Immediate adjustment took significantly longer than deferred adjustment (p < 0.001). This study shows that in patients using MDD systems, over half of the drug regimen changes are adjusted immediately. The necessity of these immediate changes should be critically evaluated.

Delayed placement of implant abutments has been associated with peri-implant marginal bone loss; however, long-term results obtained by modifying surgical and prosthetic techniques after implant placement are still lacking. This study aimed to evaluate the marginal bone loss around titanium implants placed in fresh extraction sockets using two loading protocols after a 5-year follow-up period. A total of 36 patients received 40 titanium implants (Astra Tech) intended for single-tooth replacement. Implants were immediately placed into fresh extraction sockets using either a one-stage (immediate loading by placing an interim prosthesis into functional occlusion) or a two-stage prosthetic loading protocol (insertion of abutments after 8 weeks of healing time). Marginal bone levels relative to the implant reference point were evaluated at four time intervals using intraoral radiographs: at time of implant placement, and 1, 3, and 5 years after implant placement. Measurements were obtained from mesial and distal surfaces of each implant (α = 0.05). One-stage immediate implant placement into fresh extraction sockets resulted in a significant reduction in marginal bone loss (p < 0.002) compared to the traditional two-stage technique. Whereas mesial surfaces remained stable for the 5-year observation period, significant marginal bone loss was observed on distal surfaces of implants after cementation of interim prostheses (p < 0.007) and after 12 months (p < 0.034). Within the limitations of this study, immediate loading of implants placed into fresh extraction sockets reduced marginal bone loss and did not compromise the success rate of the restorations. © 2014 by the American College of Prosthodontists.

Clinical Outcome After 8 to 10 Years of Immediately Restored Single Implants Placed in Extraction Sockets and Healed Ridges.

PubMed

Raes, Stefanie; Cosyn, Jan; Noyelle, Anabel; Raes, Filiep; De Bruyn, Hugo

Recent systematic reviews point to the scarcity of single implants followed up longer than 5 years, and the incidence of biologic/technical complications is underreported. This prospective follow-up study documents 8- to 10-year clinical outcomes of immediately restored single implants in extraction sockets (immediate implant treatment [IIT]) and healed bone (conventional implant treatment [CIT]). Patients received a single, chemically modified, moderately rough titanium implant and a provisional crown on the day of surgery in the anterior maxilla (second premolar to second premolar). Provisional crowns were replaced by permanent crowns after 10 weeks. Implant survival, complications, crestal bone changes, plaque score, probing depth, and bleeding on probing were regularly recorded up to 10 years of follow-up. Of 16 patients who underwent IIT, 11 could be evaluated after 8 years. Of the 23 patients who received an implant in healed bone, 18 were finally evaluated. One implant failed in the IIT group at 12 weeks; all implants survived in the CIT group; 38% of the patients experienced at least one complication; 10% had one or more biologic complications, whereas 31% experienced one or more technical complications. There were no significant changes in crestal bone level from 1 to ≥ 8 years of follow-up for either group or between IIT and CIT at any time point (P ≥ .129). Only 6.9% (2 of 29) implants demonstrated progressive bone loss > 2 mm combined with pockets ≥ 6 mm. Immediately restored single implants in extraction sockets and healed ridges demonstrate good long-term outcomes in terms of implant survival, crestal bone loss, and peri-implant health. However, biologic and especially technical complications are common.

Scenes of fathering: The automobile as a place of occupation.

PubMed

Bonsall, Aaron

2015-01-01

While occupations are increasingly analyzed within contexts, other than the home, the ordinary places that facilitate occupations have been overlooked. The aim of this article is to explore the automobile as a place of occupation using data from an ethnographic study of fathers of children with disabilities. Qualitative data obtained through observations and interviews with the fathers and their families were analyzed using a narrative approach. Properties that influence interactions include opportunities to communicate, the vehicle itself, and electronics. Driving children in the automobile fulfills fathering responsibilities and is a time for connecting. For the fathers in this study, the automobile represents a place for negotiating complex demands of fathering. This study demonstrates not only the importance of the automobile, but also the influence of the immediate space on the construction of occupations.

The purpose of the present study was to evaluate if the presence of granulation tissue in asymptomatic apical periodontitis compromised immediate implant placement. Patients requiring extraction of one tooth (maxillary and mandibular incisive, canine or premolar) with asymptomatic apical periodontitis, were recruited for this prospective study. They were randomly scheduled into two groups: in first group (A) including 30 teeth, reactive soft tissue was debrided before implant placement, and in second group (B) including 30 teeth, reactive soft tissue was left in the apical lesion. Implants were positioned immediately after tooth extraction, and were loaded after 3 months in both groups. Cone beam computed tomography was performed before tooth extraction and at 1-year follow-up to evaluate the radiolucency around the root apex and the implant, bucco-lingual bone levels were also checked. Sixty patients were included in this study. Sixty implants were placed immediately after tooth extraction and, at 1-year follow-up, a survival rate of 100% was reported. After one year both groups showed absence of radiolucent zone at the apical region of implants. All fresh sockets presented a buccal-palatal bone reduction in both groups after one year, even if not statistically significant differences were found between baseline bone levels and within groups. Within the limitations of the present study, the immediate placement of implants into the extraction sockets with asymptomatic apical periodontitis, in presence of primary stability, did not lead to an increased rate of complications and rendered an equally favorable type of tissue integration. © 2016 Wiley Periodicals, Inc.

Exposure to air pollution and its sources is increasingly viewed as a psychosocial stress, however its nature is not understood. This article explores the role of the concept of place on risk perception and community stress within data collected from eight focus groups in Philadelphia, USA. Discussions focused on air pollution, a nearby oil refinery, health, and a proposal for air monitoring. We present a framework of place-based elements of risk perception that includes place identity, stigma and social control. Our findings indicate that air pollution contributes to physical and psychosocial conditions that act as community-level social stressors. Findings also suggest that programs which seek to change behaviors and gather or spread information on issues such as pollution and other environmental concerns will be challenged unless they directly address: (1) the public׳s identification with a place or industry, (2) immediate environmental stressors such as abandonment, waste and odors, and (3) public perceptions of lack of social control and fear of displacement.

Immediate loading of titanium hexed screw-type implants in the edentulous patient: case report.

PubMed

Calvo, M P; Muller, E; Garg, A K

2000-01-01

Histologic and histomorphometric studies in both animals and humans have shown that more rapid and greater bone-to-implant contact can be achieved with implants that incorporate certain surface characteristics compared with the original machined-surface implants. Such findings are significant because various implant designs may allow the fixtures to sufficiently resist functional loading sooner than originally thought. The case report presented here indicates that immediate loading of hexed titanium screw-type implants in the anterior mandible can lead to successful osseointegration and clinical outcome. The number of implants placed, their distribution, and the type of rigid connection are critical considerations for immediate loading. A bone height that can accommodate dental implants > or = 10 mm long is recommended. Biomechanically, the implants to be immediately loaded must be stable and resistant to macromovement to ensure good osseointegration.

[A PhD completed 1. Immediate dental implant placement in the aesthetic zone].

PubMed

Slagter, K W

2016-05-01

When aesthetics play a role in an extraction, the tendency is to place an implant in the extraction socket immediately, preferably in combination with a temporary crown. This tendency is probably related to evolving social factors: demanding patients who want an instant and attactive result. In 2 randomised clinical trials (total 80 patients) the results of clinical treatment involving immediate implants in the aesthetic zone are investigated. Depending on the size of the bone defect (< 5 or ≥ 5 mm) the number of surgical interventions was reduced from 2 to 1 or from 3 to 2. The treatment result was measured by the following outcome variables: survival rate, changes in hard and soft -peri-implant tissues, aesthetic indecees and patient-satisfaction. The most important conclusion is that immediate placements of implants in the aesthetic zone, results in -outstanding short-term (1-year) results with respect to the outcome variables. If this also leads to good long-term results has yet to be investigated.

Writing place: a comparison of nursing research and health geography.

PubMed

Carolan, Mary; Andrews, Gavin J; Hodnett, Ellen

2006-09-01

The concept of 'place', and general references to 'geographies of ...' are making gradual incursions into nursing literature. Although the idea of place in nursing is not new, this recent spatial turn seems to be influenced by the increasing profile of the discipline of health geography, and the broadening of its scope to incorporate smaller and more intimate spatial scales. A wider emphasis within the social sciences on place from a social and cultural perspective, and a wider turn to 'place' across disciplines are probably equally important factors. This trend is raising some interesting questions for nurses, but at the same time contributes some confusion with regard to imputed meanings of 'place'. While it is clear that most nurse clinicians and researchers certainly understand that place of care matters to their practices and patients, many diverse uses of 'place' are found within nursing literature, and contemporary understandings of the term 'place' within nursing are not immediately clear. It is in this context that this article plans to advance the discussion of place. More specifically, the aims of this paper are threefold: to critique 'place' as it appears in nursing literature, to explore the use of 'place' within health geography, whence notions of place and 'geographies of' have originated and, finally, to compare and contrast the use of 'place' in both disciplines. This critique intends to address a deficit in the literature, in this era of growing spatialization in nursing research. The specific questions of interest here are: 'what is "place" in nursing?' and 'how do concepts of place in nursing compare to concepts of place in health geography?'

Is testing a more effective learning strategy than note-taking?

PubMed

Rummer, Ralf; Schweppe, Judith; Gerst, Kathleen; Wagner, Simon

2017-09-01

The testing effect is both robust and generalizable. However, most of the underlying studies compare testing to a rather ineffective control condition: massed repeated reading. This article therefore compares testing with note-taking, which has been shown to be more effective than repeated reading. Experiment 1 is based on a 3 × 3 between-participants design with the factors learning condition (repeated reading vs. repeated testing vs. repeated note-taking) and final test delay (5 min vs. 1 week vs. 2 weeks). It shows that in the immediate condition, learning performance is best after note-taking. After 1 week, both the note-taking and the testing groups outperform the rereading group, and after 2 weeks, testing is superior to both note-taking and rereading. Since repeated notetaking may not be the most effective (and common) operationalization of note-taking, Experiment 2 contrasts repeated testing with 2 other note-taking conditions: note-taking plus note-reading and note-taking plus testing (with only a 2-week final test delay). Both conditions that include a testing phase result in better long-term learning than note-taking plus note-reading. In summary, our findings indicate that-in the long run-testing is a powerful learning tool both in isolation and in combination with note-taking.

Within the limitations, it can be concluded that immediately placed, restored, or loaded single-tooth implants in the esthetic zone result in similar hard and soft tissue changes compared with conventional protocols.

Background. In the current scientific literature there are only few studies on the immediate functional loading of single implants. The aim of the present present study was to evaluate the 4-year survival rate, complication rate and peri-implant marginal bone loss (PIMBL) of immediately loaded single implants inserted in healed ridges and fresh post-extraction sites. Methods. Six centers were involved in this prospective study. The surgical and prosthetic protocol was defined in detail, before the start of recruiting patients. Recruitment of patients and performance of surgeries took place between February 2012 and February 2013. Criteria for inclusion were single-tooth gaps in healed ridges and fresh post-extraction sockets. All the fixtures (Anyridge®, Megagen Corporation, Gyeongbuk, South Korea) were functionally loaded immediately after insertion and followed for a period of 4 years. Outcome measures were implant survival, complications and PIMBL. Results. Forty-six patients (18‒73 years of age) were selected. In total, 57 fixtures were placed (10 in fresh post-extraction sockets). After 4 years of functional loading, only one fixture was lost; therefore, high survival rates (97.6% patient-based; 98.1% implant-based) were reported. In addition, a limited incidence of biologic (4.8% patient-based; 3.8% implant-based) and prosthetic (9.7% patient-based; 7.6% implant-based) complications was reported. The overall 4-year PIMBL amounted to 0.38±0.21 mm (healed ridges: 0.4±0.21 mm; fresh post-extraction sockets: 0.33±0.20 mm). Conclusion. Loading single implants immediately seems to be a highly successful treatment modality. However, long-term data are needed to confirm these positive outcomes. PMID:29732018

Implant rehabilitation delivered in accordance with the traditional protocol has proven to be highly predictable and acceptable (1). Nevertheless, the application of immediate loading on post-extraction implants, especially for aesthetic zones, has now considerably increased (2). The aim of this work is to illustrate the immediate loading of implants placed in the aesthetic zone through tapered design fixtures with microgeometry of a high degree of porosity inserted at the same time or 4-8 weeks from dental avulsion (TSA® Advance, Phibo®). A total of 15 implant fixtures of which 8 at an interval of 4-8 weeks from extraction (type 2) and the remaining according to the immediate post-extraction technique (type 1) were positioned. All implants were prosthesized within 24 hours from the placement. Definitive crowns replaced provisional restorations after 20-24 weeks. After 4 and 12 months from implant insertion, the following parameters were assessed: X-ray image, pain, mobility or suppuration, soft tissue condition and aesthetic appearance. Percentage of osseointegration was 93.75%, and 53.5% of the osseointegrated fixtures was type 2. No statistically significant difference between the mean ISQ values for implants of type 1 and 2 both in the post-operative period and after 12 months was evident, indicating that the timing of insertion did not affect the achievement of stability for the implant fixtures tested in our study. Immediate post-extraction implants showed a greater propensity for gingival recession and a peri-implant radiolucency greater than those placed at an interval of 4-8 weeks. The values obtained for the PES/WES and the subjective evaluation of the analyzed sample showed the considerable aesthetic value and the high level of satisfaction guaranteed by the implant technique illustrated. Although well-designed, high quality, randomized clinical trials are still needed as well as the requirement to establish a common, complete, and reproducible index

Negative affect (NA) and positive affect (PA) in the early postpartum period have been associated with postpartum depressive symptoms, but the exact relationship is not well understood. This study aimed to determine if NA and PA in the immediate postpartum period predicted postpartum depressive symptoms over and above well-established predictors (previous trauma, history of depression). Participants were prospectively recruited from a Mother-Baby Unit at a large Midwestern academic medical center in the United States from April 2011 to April 2014. Participants (N=526) completed the Daily Experiences Questionnaire (DEQ), a self-report measure which assessed NA and PA, within three days post-delivery. Participants then reported their depressive symptoms at two weeks (n=364) and twelve weeks postpartum (n=271). Hierarchical regression analyses indicated that low PA and high NA after birth significantly predicted depressive symptoms early (at 2 weeks) and later (at 12 weeks) in the postpartum period, over and above previous traumatic experiences and history of depression. The sample was relatively homogenous, and data were from self-report instruments. The current study found NA and PA in the days immediately after birth predicted depressive symptoms at multiple time points in the postpartum period. Because the perinatal period places women at a higher risk for depressive symptomatology, prevention and early intervention are critical. Measuring affect in hospitals immediately after birth may provide a more normalized set of items that is predictive of later depression, which will allow physicians to identify those at highest risk for developing depressive symptoms.

Essential qualities of children’s favorite places

NASA Astrophysics Data System (ADS)

Prakoso, S.

2018-03-01

This paper builds on an existential-phenomenology framework to better understand the essential qualities of children’s favorite places. Based on grounded theory, this study focused on the everyday life experiences of 25 children (14 girls and 11 boys), aged 9–12 years and living in Jakarta, whose housing environments reflected various spatial qualities. The results showed that all children reported having one or more favorite places. Despite differences in type, scale, form, and location of children’s favorite places, each existential place was a supportive urban space conceived, perceived, and lived through the meaning and symbolic use given to it by a child. The essential qualities of children’s favorite places were accessibility, a location within route from home to other destinations (such as a friend’s house or school), and a space providing a sense of comfort, security, and social affiliation, as well as experiences that were restorative, personal, sensory, and materialistic. This study may have implications for the design of urban places that foster the formation of children’s favorite spaces by taking into account these essential qualities of children’s lived-existential spaces.

Objective This study was conducted to evaluate clinically and radiographically the use of a cellular dermal matrix allograft (Alloderm) in combination with PLA/PGA (Fisiograft) around immediate implants. Materials and Methods Fourteen patients were included in this study, three patients received two implants, total of seventeen implants were placed. Periapical radiographs and orthopantomographs were taken. The selected teeth were extracted atraumatically after the reflection of full thickness flaps. One-piece Zimmer implants were placed immediately into the sockets. Weeks from implantation, radiographic evaluation was made at 6 Fisiograft in powder form was placed in the osseous defects around the implants. The implants were immediately restored with provisional crowns free from occlusion. Patients were clinically evaluated at 3, 6, and 14 months after loading which was done after 6 weeks from implantation. Radiographic evaluation was made at 6 and 14 months from implant placement. Results showed that immediate implantation was successful in sixteen out of seventeen implants, clinical parameters regarding plaque index, gingival index, there was a slight decrease through the follow-up periods from 3 to 14 months but it was non-significant, while there was a significant decrease in the probing depth. Radiographically there was a significant increase in the bone density from 6 to 14 months post loading, while the vertical bone defect was significantly decreased. The fisiograft functioned well as space maker and scaffolding material. The Alloderm performed well as a membrane to be used in association with immediate implants and it has a good potentiality for increasing the width of the keratinized gingiva, which is an important feature for implant esthetics. Conclusion the combination technique between the bone graft and the membrane proved to be successful to overcome dehiscence and osseous defects around immediate implants. PMID:25780357

Recently, a new implant surface texture, featuring application of nanometer-scale calcium phosphate has been shown to enhance early bone fixation and formation in preclinical studies and in human histomorphometric studies, which may be beneficial in immediate loading situations. The purpose of the present prospective clinical study was to, during 1 year, clinically and radiographically evaluate a nanometer scale surface modified implant placed for immediate loading of fixed prostheses in both maxillary and mandibular regions. Thirty-five out of 38 patients who needed implant treatment and met inclusion criteria agreed to participate in the study and were consecutively enrolled. Surgical implant placement requirements consisted of a final torque of a least 25 Ncm prior to final seating and an implant stability quotient above 55. A total of 102 NanoTite PREVAIL (NTP) implants (BIOMET 3i, Palm Beach Gardens, FL, USA) (66 maxillary and 36 mandibular) were placed by one investigator, and the majority of these were placed in posterior regions (65%) and in soft bone (69%). A total of 44 prosthetic constructions were evaluated consisting of 14 single-tooth restorations, 26 fixed partial dentures, and four complete fixed restorations. All provisional constructions were delivered within 1 hour, and the final constructions placed after 4 months. Implants were monitored for clinical and radiographic outcomes at follow-up examinations scheduled for 3, 6, and 12 months. Of the 102 study implants, one implant failed. The simple cumulative survival rate value at 1 year was 99.2%. The average marginal bone resorption was 0.37 mm (SD 0.39) during the first year in function. According to the success criteria of Albrektsson and Zarb, success grade 1 was found with 93% of the implants. Although limited to the short follow-up, immediate loading of NanoTite Prevail implants seems to be a viable option in implant rehabilitation, at least when a good initial fixation is achieved.

To measure the buccal plate reconstruction of extraction sockets with labial plate dehiscence defects using a bone allograft in combination with an absorbable collagen membrane and a custom-healing abutment at the time of tooth removal. Ten patients underwent immediate implant placement and reconstruction of the buccal plate. Cone beam computed tomography (CBCT) was performed preextraction, immediately after bone grafting and implant placement (day 0), and between 6 and 9 months following implant surgery. Measurements were taken at three levels: coronal (L1), middle (L2), and apical (L3) level. Implants placed into sockets with labial plate dehiscence defects demonstrated radiographic reformation of the labial plate dehiscence defect at 6 to 9 months posttreatment. The net gain in labial plate on cone beam computerized tomography (CBCT) in L1 and L2 was 3.0 mm, where 0 mm existed at pretreatment. The minimum amount of labial plate thickness of 2.0 mm was achieved in all treated sites, evaluated radiographically at 6 to 9 months postoperatively, in a single procedure, without flap elevation and maintaining the gingival architecture and satisfactory esthetics. Placing an absorbable membrane, bone graft, and custom-healing abutment at the time of flapless anterior tooth extraction and immediate implant placement into a socket with a labial osseous dehiscence is a viable clinical technique to reconstitute the absence of the labial bone plate. © 2015 Wiley Periodicals, Inc.

Immediate, non-submerged, root-analogue zirconia implant in single tooth replacement.

PubMed

Pirker, W; Kocher, A

2008-03-01

This report demonstrates the successful clinical use of a modified root-analogue zirconia implant for immediate single tooth replacement. A right maxillary premolar was removed and a custom-made, root-analogue, roughened zirconia implant with macro-retentions in the interdental space was fabricated and placed into the extraction socket 4 days later. Four months after root implantation a composite crown was cemented. No complications occurred during the healing period. An excellent esthetic and functional result was achieved with the composite crown. No clinically noticeable bone resorption or soft-tissue recession was observed at 26 months follow up. Significant modifications such as macro-retentions seem to indicate that primary stability and excellent osseointegration of immediate root-analogue zirconia implants can be achieved, while preventing unesthetic bone resorption. The macro-retentions must be limited to the interdental space to avoid fracture of the thin buccal cortex. This successful case warrants further clinical research in well controlled trials.

Success and High Predictability of Intraorally Welded Titanium Bar in the Immediate Loading Implants

PubMed Central

Fogli, Vaniel; Camerini, Michele; Carinci, Francesco

2014-01-01

The implants failure may be caused by micromotion and stress exerted on implants during the phase of bone healing. This concept is especially true in case of implants placed in atrophic ridges. So the primary stabilization and fixation of implants are an important goal that can also allow immediate loading and oral rehabilitation on the same day of surgery. This goal may be achieved thanks to the technique of welding titanium bars on implant abutments. In fact, the procedure can be performed directly in the mouth eliminating possibility of errors or distortions due to impression. This paper describes a case report and the most recent data about long-term success and high predictability of intraorally welded titanium bar in immediate loading implants. PMID:24963419

Abstract Purpose: Single-incision videoendoscopic surgery has recently become popular as a result of the ongoing search for less invasive procedures. The aim of this study was to evaluate the safety and efficacy of endoscopic single-port nipple-sparing mastectomy, axillary lymphadenectomy, and immediate reconstruction in patients with breast cancer. Patients and Methods: From May 14, 2012 through January 23, 2013, 10 patients underwent videoendoscopic single-port nipple-sparing mastectomy and axillary dissection via a single, limited incision and immediate prosthetic reconstruction. Patient charts were reviewed, and demographic data, operative time, complications and pathology results were analyzed. Results: In all patients, videoendoscopic surgery was performed successfully. Of 10 patients, 7 were diagnosed as having invasive ductal carcinoma, 2 had a ductal carcinoma in situ, and 1 underwent bilateral prophylactic mastectomy. The weight of the resected gland was 300–650 g, with a mean of 420 g. There were no operative complications, and the mean operative time was 250 minutes (range, 160–330 minutes). One-stage reconstruction with implants was performed on 4 patients, whereas expanders were placed in the remaining 6. Surgical margins of all cases were pathologically negative, and there were no recurrences observed during the early follow-up period. Conclusions: Videoendoscopic single-port nipple-sparing mastectomy is technically feasible even in larger breasts, enabling immediate reconstruction with good cosmetic outcomes. However, further studies with larger clinical series and long-term follow-up are required to compare the safety and efficacy of the technique with those of the standard nipple-sparing mastectomy.

The purpose of this study was to determine whether posters placed on the platforms of two train stations in Copenhagen, promoting use of the stairs, would encourage people to use the stairs rather than the adjacent escalator. An additional purpose was to see if the effect of the intervention was maintained for a week after the poster was removed. The number of people using stairs and escalators at Copenhagen Central Station and Østerport Train Station in Copenhagen was recorded before and during posters promoting stair use were placed on the platforms, and a week after the posters were removed. Two years after the posters were removed, data were collected for 1 week at Østerport Train Station (long-term post-intervention). At Copenhagen Central Station, the overall stair use increased from 12% before the intervention to 16% (P<0.0001) during the intervention, giving an odds ratio (OR) of 1.5 for stair use. At Østerport Train Station in Copenhagen, the overall stair use increased from 23 to 31% during the intervention (P<0.0001), and dropped to 27% (P<0.0001) after the intervention (during the intervention, OR=1.5 (P<0.0001); after the intervention, OR=1.2 (P<0.0001)). At the long-term post-intervention recording, the overall stair use was 25%, which was not significantly different from the stair use found before the intervention. Posters promoting stair use placed on the platforms of train stations can result in increased stair use, during and after 1 week of intervention, and thereby seem useful only when up and immediately following intervention in changing health-promoting behavior among Danish men and women. These results agree well with results from other countries.

Immediate extinction causes a less durable loss of performance than delayed extinction following either fear or appetitive conditioning.

PubMed

Woods, Amanda M; Bouton, Mark E

2008-12-01

Five experiments with rat subjects compared the effects of immediate and delayed extinction on the durability of extinction learning. Three experiments examined extinction of fear conditioning (using the conditioned emotional response method), and two experiments examined extinction of appetitive conditioning (using the food-cup entry method). In all experiments, conditioning and extinction were accomplished in single sessions, and retention testing took place 24 h after extinction. In both fear and appetitive conditioning, immediate extinction (beginning 10 min after conditioning) caused a faster loss of responding than delayed extinction (beginning 24 h after conditioning). However, immediate extinction was less durable than delayed extinction: There was stronger spontaneous recovery during the final retention test. There was also substantial renewal of responding when the physical context was changed between immediate extinction and testing (Experiment 1). The results suggest that, in these two widely used conditioning preparations, immediate extinction does not erase or depotentiate the original learning, and instead creates a less permanent reduction in conditioned responding. Results did not support the possibility that the strong recovery after immediate extinction was due to a mismatch in the recent "context" provided by the presence or absence of a recent conditioning experience. Several other accounts are considered.

To Take or Not to Take: Decision-Making About Antiretroviral Treatment in People Living with HIV/AIDS

Kremer, Heidemarie; Ironson, Gail; Schneiderman, Neil; Hautzinger, Martin

2008-01-01

Knowledge is limited regarding decision-making about antiretroviral treatment (ART) from the patient’s perspective. This substudy of a longitudinal study of psychobiologic aspects of long-term survival, conducted in 2003, compares the rationales of HIV-positive individuals (n = 79) deciding to take or not to take ART. Inclusion criteria were HIV/AIDS symptoms, or CD4 nadir less than 350, or viral load greater than 55,000. Those not meeting any criteria for receiving ART (2/2003 U.S. DHHS treatment guidelines) were excluded. Diagnosis was on average 11 years ago; 36% were female, 42% African American, 28% Latino, 24% white, and 6% other. Qualitative content analysis of semistructured interviews identified 10 criteria for the decision to take or not to take ART: CD4/viral load counts (87%), quality of life (85%), knowledge/beliefs about resistance (66%), mind–body beliefs (65%), adverse effects of ART (59%), easy-to-take regimen (58%), spirituality/worldview (58%), drug resistance (41%), experience of HIV/AIDS symptoms (39%), and preference for complementary/alternative medicine (17%). Participants choosing not to take ART (27%) preferred complementary/alternative medicine (r = 0.43, p < 0.001)1, perceived a better quality of life without ART (r = 0.32, p < 0.004), and weighted avoidance of adverse effects of ART more heavily (r = 0.24, p < 0.030) than participants taking ART (73%). Demographic characteristics related to taking ART were having a partner (r = 0.31, p < 0.008) and having health insurance (r = 0.26, p < 0.040). Decisions to take or not to take ART depend not only on patient medical characteristics, but also on individual beliefs about ART, complementary/alternative medicine, spirituality, and mind–body connection. HIV-positive individuals declining treatment place more weight on alternative medicine, avoiding adverse effects and perceiving a better quality of life through not taking ART. PMID:16706708

Immediate implant placement into posterior sockets with or without buccal bone dehiscence defects: A retrospective cohort study.

To evaluate bone reconstruction and soft tissue reactions at immediate implants placed into intact sockets and those with buccal bone dehiscence defects. Fifty-nine internal connection implants from four different manufacturers were immediately placed in intact sockets(non-dehiscence group, n=40), and in alveoli with buccal bone dehiscence defects: 1) Group 1(n= N10), the defect depth measured 3-5 mm from the gingival margin. 2) Group 2(n=9), the depth ranged from 5mm to 7mm. The surrounding bony voids were grafted with deproteinized bovine bone mineral (DBBM) particles. Cone beam computed tomography(CBCT) was performed immediately after surgery (T1), and at 6 months later(T2). Radiographs were taken at prosthesis placement and one year postloading(T3). Soft tissue parameters were measured at baseline (T0), prosthesis placement and T3. No implants were lost during the observation period. For the dehiscence groups, the buccal bone plates were radiographically reconstructed to comparable horizontal and vertical bone volumes compared with the non-dehiscence group. Marginal bone loss occurred between the time of final restoration and 1-year postloading was not statistically different(P=0.732) between groups. Soft tissue parameters did not reveal inferior results for the dehiscence groups. Within the limitations of this study, flapless implant placement into compromised sockets in combination with DBBM grafting may be a viable technique to reconstitute the defected buccal bone plates due to space maintenance and primary socket closure provided by healing abutments and bone grafts. Immediate implants and DBBM grafting without using membranes may be indicated for sockets with buccal bone defects. Copyright © 2017 Elsevier Ltd. All rights reserved.

Periotest values of implants placed in sockets augmented with calcium phosphosilicate putty graft: a comparative analysis against implants placed in naturally healed sockets.

Mahesh, Lanka; Narayan, Tv; Kostakis, Georgios; Shukla, Sagrika

2014-03-01

To measure implant stability using periotest values of implants placed in sockets augmented with calcium phospho-silicate putty (CPS Putty) as compared with implant stability in naturally healed sockets. Twenty two sockets were implanted with CPS Putty immediately after extraction. The sockets were re-entered after a healing period at 5 to 6 months (average 5.3 months) for implant placement. Periotest values were recorded during implant insertion to assess primary stability. These were compared with the Periotest values of 26 implants placed in 22 patients, with naturally healed sockets. Periotest values were significantly lower in the grafted group, indicating better implant stability in sites grafted with CPS putty. Implant stability seems to be significantly higher in sockets augmented using CPS putty when compared to nongrafted sites. This suggests that socket grafting with CPS putty may enhance the quality of available bone for implantation.

How long does it take a static speaking individual to contaminate the immediate environment?

Developments in forensic genetic profiling mean that only a very little DNA is required to generate an identifying profile. However, as this sensitivity increases so does the risk of contamination with non-offender DNA, potentially leading to the conviction of innocents, or release of the guilty. The work of Rutty et al. showed that a static and talking person deposited DNA in front of them within a 15-minute period. This work expands on that of Rutty et al. by determining the time period required for an individual to deposit sufficient DNA for a positive identification to be made, and the distance that this contamination can be detected from the speaking individual. To simulate a scene of crime, sheets of Benchkote(®) were used to represent an area of interest and an unprotected subject talked over them for a variety of times, in a variety of positions (standing, kneeling, and sitting at a desk). Results show that contamination by talking in both kneeling and sitting positions occurred almost immediately (<30 seconds, but not from just one sentence) up to 69 cm from the subject. When standing, contamination could be observed up to a maximum 115 cm from the subject, and was only present in one of three repeats when talking for only 30 seconds. This article illustrates how rapidly a static person can potentially contaminate an area in front of him or herself within a laboratory or scene environment, just by talking.

The Social Determinants of Health Core: Taking a Place-Based Approach.

PubMed

Scribner, Richard A; Simonsen, Neal R; Leonardi, Claudia

2017-01-01

There is growing recognition that health disparities research needs to incorporate social determinants in the local environment into explanatory models. In the transdisciplinary setting of the Mid-South Transdisciplinary Collaborative Center (TCC), the Social Determinants of Health (SDH) Core developed an approach to incorporating SDH across a variety of studies. This place-based approach, which is geographically based, transdisciplinary, and inherently multilevel, is discussed. From 2014 through 2016, the SDH Core consulted on a variety of Mid-South TCC research studies with the goal of incorporating social determinants into their research designs. The approach used geospatial methods (e.g., geocoding) to link individual data files with measures of the physical and social environment in the SDH Core database. Once linked, the method permitted various types of analysis (e.g., multilevel analysis) to determine if racial disparities could be explained in terms of social determinants in the local environment. The SDH Core consulted on five Mid-South TCC research projects. In resulting analyses for all the studies, a significant portion of the variance in one or more outcomes was partially explained by a social determinant from the SDH Core database. The SDH Core approach to addressing health disparities by linking neighborhood social and physical environment measures to an individual-level data file proved to be a successful approach across Mid-South TCC research projects.

You visit a special natural setting and are amazed at the splendor. You revisit it years later at the same time of year and note how it has changed. The environment looks different-algae is growing where it didn't before. Trees are dying. Weeds are flourishing. You ask yourself "why is this happening?" The spark starting your climate place-based awareness just ignited. The GLOBE program encourages and enables young citizen scientists to observe and record measurements related to the environment and to use those measurements for research. Over 130 learning activities supplement the 51 measurement protocols that can be done in and out of the field, with and without technical devices that open up the mind to questions about one's environment. From taking pictures of the sky to creating instruments, to noting when plants bloom and examining the characteristics of the soil and land, GLOBE encourages investigating climate change in numerous ways. GLOBE activities encouraging climate awareness and "what if" scenarios fuel student research and help validate scientific research. Studying one's local GLOBE observations and seeing where and when change occurs, brings out intrigue that expands to investigating multiple places where even more questions can arise-fueling the scientific process and encouraging place-based learning.

The anatomical remodeling technique (ART) was proposed to place postextraction implants with the aid of specific osteotomes. This study is a clinical and radiographic evaluation with 10-year follow-up of anterior postextraction single implants placed with the ART and immediately restored. Thirty-five patients, with a hopeless tooth in the anterior maxilla, were included in the study and 35 implants were inserted according to the ART. Clinical and radiographic evaluations were performed at baseline (T0), after 6 (T1) and 14 months (T2), 4 years after surgery (T3) and every other year up to the 10-year follow-up (T4, T5, and T6). Implant success, survival, and failure rates were evaluated according to the International Congress of Oral Implantologists Pisa Consensus Conference criteria. Twenty-nine patients and 29 implants were available for the 10-year data analysis. After 10 years, the accumulated mean marginal bone loss was 2.69 ± 0.42 mm. The cumulative survival rate of the implants was 100%. Immediately loaded postextractive implants, placed according to the ART, have been proved to be a predictable method to rehabilitate single tooth in the anterior maxilla.

Understanding stakeholders' attitudes toward water management interventions: Role of place meanings

NASA Astrophysics Data System (ADS)

Jacobs, Maarten H.; Buijs, Arjen E.

2011-01-01

Water resource managers increasingly need to take the opinions of stakeholders into account when planning interventions. We studied stakeholders' concerns in two water management planning contexts, focusing on the meanings assigned to places and on attitudes toward proposed interventions. Semistructured interviews were held, and public meetings were observed in order to collect data. Five categories of place meanings emerged from the analysis: beauty (esthetic judgments), functionality (ways of use), attachment (feelings of belonging), biodiversity (meanings pertaining to nature), and risk (worries about current or future events). These categories reflect the basic dimensions of sense of place. Our results suggest that stakeholders' attitudes toward proposed interventions are, to a great extent, derived from their place meanings. Discussing place meanings during participatory planning processes could contribute substantially to successful water management.

2004-05-01

The aim of the present study was to assess the efficacy of a ready-to-use injectable bone substitute for bone regeneration around dental implants placed into fresh extraction sockets. Third and fourth mandibular premolars were extracted from three beagle dogs and the interradicular septa were surgically reduced to induce a mesial bone defect. Thereafter, titanium implants were immediately placed. On the left side of the jaw, mesial bone defects were filled with an injectable bone substitute (IBS), obtained by combining a polymer and biphasic calcium phosphate ceramic granules. The right defects were left unfilled as controls. After 3 months of healing, specimens were prepared for histological and histomorphometric evaluations. No post-surgical complications were observed during the healing period. In all experimental conditions, histological observations revealed a lamellar bone formation in contact with the implant. Histomorphometric analysis showed that IBS triggers a significant (P<0.05) increase in terms of the number of threads in contact with bone, bone-to-implant contact, and peri-implant bone density of approximately 8.6%, 11.0%, and 14.7%, respectively. In addition, no significant difference was observed when number of threads, bone-to-implant contact, and bone density in the filled defects were compared to the no-defect sites. It is concluded that an injectable bone substitute composed of a polymeric carrier and calcium phosphate significantly increases bone regeneration around immediately placed implants.

Endoscopically placed nitinol stents for pediatric tracheal obstruction.

2002-11-11

To provide preliminary clinical data regarding endoscopically placed nitinol stents for children with tracheal obstruction as a temporizing measure to allow for trach tube decannulation while awaiting growth to allow for tracheal resection. This case series describes the experiences of two children (ages 5 and 15) who were dependent upon tracheotomy because of acquired tracheal obstruction. Both patients had combined tracheomalacia and tracheal stenosis. After failing tracheoplasty with rib graft augmentation both patients suffered from extensive tracheal disease, which was too long to allow for immediate tracheal resection. Endoscopic placement of nitinol stents in the obstructed tracheal segment using fluoroscopic guidance. All tracheotomy tubes were removed immediately after successful stent deployment with the patient still under general anesthesia. Four stents were placed in total. The first patient's initial stent was too narrow and was, therefore, removed and replaced at a later date with a larger diameter stent. The second patient experienced distal migration of his initial stent requiring stent removal and replacement at a later date. Both patients remain successfully decannulated (follow-up, 25 and 26 months) and are currently living more normal lives as they grow and await tracheal resection. Preliminary use of nitinol stents for pediatric tracheal obstruction has enabled successful decannulation in two children with complicated airways. Our results with this series of patients suggest that nitinol stents can be safely used in children as a temporizing measure until tracheal resection can be safely performed. With this approach children can live free from the hassles of trach care, social isolation and peer ridicule. Limited pediatric experience exists in the literature about nitinol stents. Thus, our experience with stent selection and placement will help others avoid problems encountered in this initial series. Copyright 2002 Elsevier Science Ireland

Early Complications of Immediate Loading in Edentulous Full-Arch Restorations: A Retrospective Analysis of 88 Cases.

PubMed

Cercadillo-Ibarguren, Iñaki; Sánchez-Torres, Alba; Figueiredo, Rui; Valmaseda-Castellón, Eduard

To describe the clinical outcomes and complications related to provisional prostheses after full-arch implant-supported rehabilitation by means of an immediate loading protocol. This retrospective cohort study included patients who were consecutively treated with full-arch implant-supported restorations with a minimum of four implants (Replace Select Tapered TiUnite, Nobel Biocare AB) per arch and conical abutments (multi-unit, Nobel Biocare AB) by means of an immediate loading protocol. The surgical procedures were performed between May 2006 and June 2014 by a single oral surgeon. Demographic, surgical, and prosthetic variables were collected, and biologic and mechanical complications were registered. A total of 61 maxillae (57%) and 46 mandibles (43%) were treated in 88 patients (40 men and 48 women) with a mean age of 62.4 years. A total of 558 implants were placed, 295 in postextraction sockets. A total of 331 implants (59.3%) were placed in the maxilla and 227 (40.7%) in the mandible. Within a 9-month period, 18 prostheses (16.8%) fractured (15 maxillary and 3 mandibular); in nine of these patients the opposing dentition was a full-arch, implant-supported restoration, and in the remaining nine patients, it was natural dentition. Six (1.1%) maxillary and three (0.5%) mandibular implants failed. A high implant survival rate is expected in the short term following this immediate loading protocol. Fracture of the provisional prosthesis is a common finding, affecting 17% of patients, and is significantly more prevalent in patients with bruxism and in maxillary prostheses.

Immediately-loaded, narrow-diameter implants can be a less invasive alternative for the implant-supported fixed rehabilitation of narrow, posterior crests. To determine the stability and marginal bone level (MBL) changes of narrow-diameter, titanium-zirconium (TiZr) implants placed with flapless surgery and loaded immediately in the posterior region. Thirty-eight TiZr implants (3.3 mm diameter, 10 mm length, Roxolid, Straumann AG) were placed in the posterior crests of 14 patients with computer-guided flapless surgery as a support of 3-unit posterior bridges. Eighteen implants were loaded immediately, and 20 implants were loaded conventionally. The implant stability quotients were determined at the 1, 2, 4, and 8. weeks of healing before conventional loading, and at the 3, 6, and 12. months after loading by resonance frequency analysis. The MBL changes were measured by digital radiography. The surgical protocols were accomplished without any biological complications. There was no significant difference in the stability changes of TiZr implants between the loading groups (p > .05). The MBL changes were -0.18 ± 0.27 mm and -0.24 ± 0.27 mm at the 12. month of immediate and conventional loading, respectively, which was not statistically significant (p > .05). The stability and MBL changes of TiZr implants supporting posterior 3-unit bridges were clinically acceptable at the first year of loading. © 2016 Wiley Periodicals, Inc.

Frequency and Type of Prosthetic Complications Associated with Interim, Immediately Loaded Full-Arch Prostheses: A 2-Year Retrospective Chart Review.

PubMed

Drago, Carl

2016-08-01

The purpose of this report was to retrospectively evaluate implant and immediate full-arch prosthesis survival rates over a 24-month period; patients were consecutively treated with immediate occlusal loading. Dental arch, gender, and implant orientation (vertical vs. tilted) were also noted. All Brånemark System implants (Nobel Active) and interim, all-acrylic resin prostheses placed in patients following an All-on-Four™ protocol, in a single private practice were assessed by retrospective patient chart review. The amount of space provided surgically for implant restorative components and prostheses was determined from measurements of the vertical heights of the interim prostheses in the right/left anterior and posterior segments. These measurements were made in the laboratory. Interim prosthetic repairs (type, frequency, length of time from insertion) were analyzed by type, arch, gender, and implant orientation. Implant survival and insertion torque values were also measured. Inclusion criteria consisted of all Brånemark System implants placed with the All-on-Four protocol from September 1, 2011, until August 31, 2013. Specific dietary instructions were given for the first 7 days immediately postoperatively and for the weeks prior to insertion of the definitive prostheses. One hundred twenty-nine patients, comprising 191 arches (766 implants) from September 1, 2011, until August 31, 2013, were included in the study. One patient experienced implant failure yielding an overall implant survival rate (SR) of 99.5% (762 of 766). Four hundred twenty-six of 430 maxillary implants and 336 of 336 mandibular implants survived for SRs of 99.1% and 100%, respectively. Regarding implant orientation, 415 of 417 tilted implants (SR 99.5%) and 343 of 345 (CSR 95.6%) vertical implants were noted to be clinically stable. Interim, all-acrylic resin prostheses were in place for a mean of 199.2 days; mandibular prostheses were in place for an average of 195.4 days; maxillary

Leave taking and overtime behavior as related to demographic, health, and job variables

NASA Technical Reports Server (NTRS)

Arnoldi, L. B.; Townsend, J. C.

1969-01-01

An intra-installation model is formulated that correlates demographic, health and job related variables to the various types and amounts of leave and overtime taking behavior of employees. Statistical comparison of composite health ratings assigned to subjects based upon clinical criteria and bio-statistical data show that those employees who take the most annual leave as well as sick leave are the ones that have the poorest health ratings; employees who put in the most overtime have also the poorest health records. Stress effects of peak activity periods increase use of sick leave immediately after peak activity but not the use of annual leave.

Immediate implant-supported oral rehabilitation using a photocurable plastic skull model and laser welding. A technical note on the screw-retained type: Part 1.

2002-01-01

This article describes a new procedure for immediate implant-supported oral rehabilitation using a photocurable resin skull model and a laser-welding apparatus. Preoperatively, the framework was fabricated on a photocurable resin skull model produced from a CT scan and individually designed guide template. The implants were immediately placed using the guide template; laser welding connected the components of framework. Despite the custom-made prosthesis, the total treatment from implant placement to superstructure placement can be completed within only 1 day. This procedure for immediate implant-supported oral rehabilitation using a photocurable resin skull model and a laser-welding apparatus may be useful for any implant system and patient.

Gender bias torture in place of work.

Pathak, P R

1999-11-01

Gender bias torture specially sexual harassment of women at the work place is now a hard reality, the ultimate form of control that repressed men, especially those in position of authority, can have today. They are generally being allowed to get away with it. Mainly because women are fearful and totally unorganized, managements are complacent and the law takes much too long to work if it ever does. Global picture is horrifying. Child abuse, women abuse and even some men are sexually abused. The fear of loss of job, hostility at work and social stigma still prevent women from complaining about sexual harassment. It has been recognized as human rights violation by the Supreme Court which has even drawn up legally binding guidelines directing employers to implement preventive and remedial measures in the work place.

"Put Myself Into Your Place": Embodied Simulation and Perspective Taking in Autism Spectrum Disorders.

Embodied cognition theories hold that cognitive processes are grounded in bodily states. Embodied processes in autism spectrum disorders (ASD) have classically been investigated in studies on imitation. Several observations suggested that unlike typical individuals who are able of copying the model's actions from the model's position, individuals with ASD tend to reenact the model's actions from their own egocentric perspective. Here, we performed two behavioral experiments to directly test the ability of ASD individuals to adopt another person's point of view. In Experiment 1, participants had to explicitly judge the left/right location of a target object in a scene from their own or the actor's point of view (visual perspective taking task). In Experiment 2, participants had to perform left/right judgments on front-facing or back-facing human body images (own body transformation task). Both tasks can be solved by mentally simulating one's own body motion to imagine oneself transforming into the position of another person (embodied simulation strategy), or by resorting to visual/spatial processes, such as mental object rotation (nonembodied strategy). Results of both experiments showed that individual with ASD solved the tasks mainly relying on a nonembodied strategy, whereas typical controls adopted an embodied strategy. Moreover, in the visual perspective taking task ASD participants had more difficulties than controls in inhibiting other-perspective when directed to keep one's own point of view. These findings suggested that, in social cognitive tasks, individuals with ASD do not resort to embodied simulation and have difficulties in cognitive control over self- and other-perspective. © 2015 International Society for Autism Research, Wiley Periodicals, Inc.

The Immediate and Chronic Influence of Spatio-Temporal Metaphors on the Mental Representations of Time in English, Mandarin, and Mandarin-English Speakers

Lai, Vicky Tzuyin; Boroditsky, Lera

2013-01-01

In this paper we examine whether experience with spatial metaphors for time has an influence on people’s representation of time. In particular we ask whether spatio-temporal metaphors can have both chronic and immediate effects on temporal thinking. In Study 1, we examine the prevalence of ego-moving representations for time in Mandarin speakers, English speakers, and Mandarin-English (ME) bilinguals. As predicted by observations in linguistic analyses, we find that Mandarin speakers are less likely to take an ego-moving perspective than are English speakers. Further, we find that ME bilinguals tested in English are less likely to take an ego-moving perspective than are English monolinguals (an effect of L1 on meaning-making in L2), and also that ME bilinguals tested in Mandarin are more likely to take an ego-moving perspective than are Mandarin monolinguals (an effect of L2 on meaning-making in L1). These findings demonstrate that habits of metaphor use in one language can influence temporal reasoning in another language, suggesting the metaphors can have a chronic effect on patterns in thought. In Study 2 we test Mandarin speakers using either horizontal or vertical metaphors in the immediate context of the task. We find that Mandarin speakers are more likely to construct front-back representations of time when understanding front-back metaphors, and more likely to construct up-down representations of time when understanding up-down metaphors. These findings demonstrate that spatio-temporal metaphors can also have an immediate influence on temporal reasoning. Taken together, these findings demonstrate that the metaphors we use to talk about time have both immediate and long-term consequences for how we conceptualize and reason about this fundamental domain of experience.

Sinus elevation is a reliable and often-used technique. Success of implants placed in such situations, even with bone substitutes alone, prompted the authors of this study to strive for bone loss close to zero and research variables that cause higher or lower rates of resorption. The objective of this study is to evaluate survival rates and marginal bone loss (MBL) around implants placed in sites treated with maxillary sinus augmentation using anorganic bovine bone (ABB), and identify surgical and prosthetic prognostic variables. Fifty-five implants were placed in 30 grafted maxillary sinuses in 24 patients. Periapical radiographs were evaluated immediately after implant placement (baseline), 6 months, and at the most recent follow-up. MBL was calculated from the difference between initial and final measurements, taking into account a distortion rate for each radiograph compared with original implant measurements. Survival rate was 98.2%, with only one implant lost (100% survival rate after loading) over a mean follow-up time of 2.0 ± 0.9 years. MBL ranged from 0 to 2.85 mm: 75.9% of mesial sites and 83.4% of distal sites showed <1 mm of MBL, whereas 35.2% of mesial sites and 37% of distal sites exhibited no bone loss. MBL was significantly (P <0.05) greater in open-flap compared with flapless surgery. Within the limitations of the present study, it was concluded that maxillary sinus elevation with 100% ABB gives predictable results, and that flapless surgery results in less MBL compared with traditional open-flap surgery.

Going international? Risk taking by cryptomarket drug vendors.

Décary-Hétu, David; Paquet-Clouston, Masarah; Aldridge, Judith

2016-09-01

Since 2011, we have witnessed the rise of 'dark net' drug marketplaces known as cryptomarkets. Cryptomarkets operate on the same model as eBay as they provide a platform where authorized vendors can set up a virtual shop and place listings. Building on a growing body of literature that seeks to understand cryptomarket participants, this paper seeks to explain the decision of cryptomarket vendors to take on risk. We collected data on Silk Road 1 (SR1), the first cryptomarket launched in 2011. We propose a multilevel model that takes into account the characteristics of listings, vendors and their environment to explain the decision of vendors to take on risk. Our results demonstrate that all levels in the model significantly explain the decision to take on risk. Risk taking, operationalized as a willingness to ship drugs across international borders, was associated with the weights of drug packages mailed, the vendors' reputations and numbers of listings, the country-level perceived effectiveness of law enforcement according to experts, and the opportunities available to vendors as measured by the wealth and the drug expenditures of potential customers. Our results support some previous research findings on the factors explaining risk taking. We extend existing literature by emphasizing the relevance of the environment of drug dealers to predict risk taking. Copyright © 2016 Elsevier B.V. All rights reserved.

To assess the clinical and radiographic outcomes of immediate transmucosal placement of implants into molar extraction sockets. Twelve-month multicenter prospective cohort study. Following molar extraction, tapered implants with an endosseous diameter of 4.8 mm and a shoulder diameter of 6.5 mm were immediately placed into the sockets. Molars with evidence of acute periapical pathology were excluded. After implant placement and achievement of primary stability, flaps were repositioned and sutured allowing a non-submerged, transmucosal healing. Peri-implant marginal defects were treated according to the principles of guided bone regeneration (GBR) by means of deproteinized bovine bone mineral particles in conjunction with a bioresrobable collagen membrane. Standardized radiographs were obtained at baseline and 12 months thereafter. Changes in depth and width of the distance from the implant shoulder (IS) and from the alveolar crest (AC) to the bottom of the defect (BD) were assessed. Eighty-two patients (42 males and 40 females) were enrolled and followed for 12 months. They contributed with 82 tapered implants. Extraction sites displayed sufficient residual bone volume to allow primary stability of all implants. Sixty-four percent of the implants were placed in the areas of 36 and 46. GBR was used in conjunction with the placement of all implants. No post-surgical complications were observed. All implants healed uneventfully yielding a survival rate of 100% and healthy soft tissue conditions after 12 months. Radiographically, statistically significant changes (P<0.0001) in mesial and distal crestal bone levels were observed from baseline to the 12-month follow-up. The findings of this 12-month prospective cohort study showed that immediate transmucosal implant placement represented a predictable treatment option for the replacement of mandibular and maxillary molars lost due to reasons other than periodontitis including vertical root fractures, endodontic failures

A 42-year-old obese woman (body mass index = 30.2 kg/m) presented for urgent anterior cervical diskectomy and fusion. She had been taking oral naltrexone-bupropion extended-release (Contrave, Orexigen Therapeutics Inc, La Jolla, CA) for the past 6 months and continued using it until 12 hours preoperatively. Despite discontinuation of this medication, and employing an intraoperative and postoperative multimodal analgesia strategy, immediate pain control was inadequately achieved. Patients taking opioid antagonists who present for surgery pose unique challenges to the anesthesiologist and require extensive preoperative interdisciplinary discussions and planning for pain control throughout the perioperative period.

Objectives: The purpose of this study was to compare the outcomes of immediate and delayed rehabilitation of edentulous jaws by means of two straight and two tilted implants after one year of function. Materials and Methods: Thirty consecutive patients (16 males, 14 females) were enrolled in this study. Two anterior straight and two posterior tilted implants were placed in each patient. According to the implant insertion torque and the need for bone grafting, implants were loaded immediately (at 72 hours) or delayed (after four months) using a fixed metal resin prosthesis. Results: One axial implant failed in the delayed group after one year of loading, resulting in cumulative implant survival rate of 99.3%. The mean marginal bone loss was 0.84mm. No significant difference was found between axial and tilted implants in the two groups (P>0.05) Conclusions: Based on the results, immediate or delayed fabrication of final prosthesis on two tilted and two axial implants did not result in significant differences in survival rates or marginal bone loss.

2016-01-01

Research has shown that tooth loss results in morphological changes in alveolar ridge that may influence the subsequent implant placement. Immediate implant placement was introduced as a possible means to limit bone resorption and reduce the number of surgical procedures following tooth extraction. Histological and clinical evidence from human clinical studies showing efficacy of immediate implants has come to light over the last decade or so. However, immediate implant placement is a challenging surgical procedure and requires proper case selection and surgical technique. Furthermore, there appears to be a lack of clinical guidelines for immediate implant placement case selection. Therefore, the aim of this mini-review is to analyze critical evidence from human studies in order to establish clinical guidelines which may help clinicians in case selection when considering immediate implant placement protocol.

Difficulties relating to bone regeneration that complicate immediate implant placement include buccal and/or lingual fenestrations, primary anchorage of the implants, and the need for protection from functional loading during the osseointegration period. The objective of this pilot study was to evaluate bone regeneration by recombinant human bone morphogenetic protein-2 (rhBMP-2) around immediate implants placed in maxillary sockets in rats. A total of 16 cylindric 0.8 x 1.8-mm commercially pure, solid titanium Implants were placed immediately after gentle extraction of the maxillary first molar teeth of 8 male Wistar rats. The sockets were randomly divided into 3 groups: group 1 (n = 6) received rhBMP-2 with polylactic acid/polyglycolic acid copolymer-coated gelatin sponge carrier; group 2 (n = 5) received only the carrier; and group 3 (n = 5) received no grafting materials following placement The rats were euthanized at 90 days postsurgery for microscopic analysis. In group 1, the implant body remained submerged completely, including the coronal part, which was fully covered by a significant amount (30% of total height) of regenerated cortical bone, even though the implant could easily be pulled out by a tweezer at the time of placement. Close approximation between the implant surface and regenerated bone could also be detected, indicating good bone-to-implant contact. In contrast, only peri-implant bone regeneration occurred in group 2, and an approximate 0.3-mm coronal part of the implant remained exposed. When no grafting materials were used (group 3), almost one third of the total length of the implant was exfoliated out of the socket when no grafting materials were used. Based on previous study and data from 16 sockets of the present study, it could be concluded that rhBMP-2 facilitated the regeneration of bone around immediate implants. In particular, the bone covering the coronal part could have been regenerated shortly after surgery, which helped to

Atraumatic acute carpal tunnel syndrome in a patient taking dabigatran.

PubMed

Sibley, Paul A; Mandel, Richard J

2012-08-01

Acute carpal tunnel syndrome is an uncommon diagnosis most often related to blunt trauma requiring immediate surgical decompression to avoid serious sequelae. Patients who present with bleeding-related acute carpal tunnel syndrome tend to have severe pain, rapid onset of swelling, and neurologic symptoms that appear early and progress rapidly secondary to mass effect. Acute carpal tunnel syndrome can occur in anticoagulated patients spontaneously or after minor trauma. This article describes a case of a 57-year-old man with progressive pain and paresthesias in the median nerve distribution after reaching for a picture frame. He was taking dabigatran, a direct thrombin inhibitor, for atrial fibrillation. He developed acute carpal tunnel syndrome secondary to spontaneous bleeding into the carpal canal and flexor tenosynovium with hematoma formation requiring surgical decompression. He reported immediate pain relief postoperatively, had no further bleeding complications, and regained full median nerve function within 2 months.Dabigatran has gained recent popularity for the treatment of atrial fibrillation. Unlike warfarin, its use does not involve regular laboratory monitoring or dose titration. The risks and benefits of dabigatran should be considered carefully by the prescriber, particularly in patients taking medications that may alter its metabolism. Aspirin and nonsteroidal anti-inflammatory drugs may have effects similar to dabigatran and may increase the risk of bleeding problems. Should acute carpal tunnel syndrome occur, the authors recommend prompt surgical decompression rather than conservative management. The modification of anticoagulant therapy should be considered on a case-by-case basis. Copyright 2012, SLACK Incorporated.

EXERCISE IMPROVES SEXUAL FUNCTION IN WOMEN TAKING ANTIDEPRESSANTS: RESULTS FROM A RANDOMIZED CROSSOVER TRIAL

Lorenz, Tierney Ahrold; Meston, Cindy May

2014-01-01

Background In laboratory studies, exercise immediately before sexual stimuli improved sexual arousal of women taking antidepressants [1]. We evaluated if exercise improves sexual desire, orgasm, and global sexual functioning in women experiencing antidepressant-induced sexual side effects. Methods Fifty-two women who were reporting antidepressant sexual side effects were followed for 3 weeks of sexual activity only. They were randomized to complete either three weeks of exercise immediately before sexual activity (3×/week) or 3 weeks of exercise separate from sexual activity (3×/week). At the end of the first exercise arm, participants crossed to the other. We measured sexual functioning, sexual satisfaction, depression, and physical health. Results Exercise immediately prior to sexual activity significantly improved sexual desire and, for women with sexual dysfunction at baseline, global sexual function. Scheduling regular sexual activity significantly improved orgasm function; exercise did not increase this benefit. Neither regular sexual activity nor exercise significantly changed sexual satisfaction. Conclusions Scheduling regular sexual activity and exercise may be an effective tool for the behavioral management of sexual side effects of antidepressants. PMID:24754044

In laboratory studies, exercise immediately before sexual stimuli improved sexual arousal of women taking antidepressants [1]. We evaluated if exercise improves sexual desire, orgasm, and global sexual functioning in women experiencing antidepressant-induced sexual side effects. Fifty-two women who were reporting antidepressant sexual side effects were followed for 3 weeks of sexual activity only. They were randomized to complete either three weeks of exercise immediately before sexual activity (3×/week) or 3 weeks of exercise separate from sexual activity (3×/week). At the end of the first exercise arm, participants crossed to the other. We measured sexual functioning, sexual satisfaction, depression, and physical health. Exercise immediately prior to sexual activity significantly improved sexual desire and, for women with sexual dysfunction at baseline, global sexual function. Scheduling regular sexual activity significantly improved orgasm function; exercise did not increase this benefit. Neither regular sexual activity nor exercise significantly changed sexual satisfaction. Scheduling regular sexual activity and exercise may be an effective tool for the behavioral management of sexual side effects of antidepressants

Brain Circuits of Methamphetamine Place Reinforcement Learning: The Role of the Hippocampus-VTA Loop.

PubMed

Keleta, Yonas B; Martinez, Joe L

2012-03-01

The reinforcing effects of addictive drugs including methamphetamine (METH) involve the midbrain ventral tegmental area (VTA). VTA is primary source of dopamine (DA) to the nucleus accumbens (NAc) and the ventral hippocampus (VHC). These three brain regions are functionally connected through the hippocampal-VTA loop that includes two main neural pathways: the bottom-up pathway and the top-down pathway. In this paper, we take the view that addiction is a learning process. Therefore, we tested the involvement of the hippocampus in reinforcement learning by studying conditioned place preference (CPP) learning by sequentially conditioning each of the three nuclei in either the bottom-up order of conditioning; VTA, then VHC, finally NAc, or the top-down order; VHC, then VTA, finally NAc. Following habituation, the rats underwent experimental modules consisting of two conditioning trials each followed by immediate testing (test 1 and test 2) and two additional tests 24 h (test 3) and/or 1 week following conditioning (test 4). The module was repeated three times for each nucleus. The results showed that METH, but not Ringer's, produced positive CPP following conditioning each brain area in the bottom-up order. In the top-down order, METH, but not Ringer's, produced either an aversive CPP or no learning effect following conditioning each nucleus of interest. In addition, METH place aversion was antagonized by coadministration of the N-methyl-d-aspartate (NMDA) receptor antagonist MK801, suggesting that the aversion learning was an NMDA receptor activation-dependent process. We conclude that the hippocampus is a critical structure in the reward circuit and hence suggest that the development of target-specific therapeutics for the control of addiction emphasizes on the hippocampus-VTA top-down connection.

Immediate placement of implants in extraction sockets for early loading is an attractive treatment modality due to reduced treatment time. However, the outcome of fluoridated implants in this situation with regard to bone levels and health of soft tissues is not well documented. To evaluate the outcome of early loading of OsseoSpeed(™) dental implants placed into fresh extraction sockets and healed bone in consecutive patients treated in a private clinic. A total of 182 OsseoSpeed(™) implants (Astra Tech Implant System, DENTSPLY Implants, Mölndal, Sweden), 72 in immediate extraction sockets and 110 in healed sites, were placed in 39 consecutive patients. The implants were loaded with permanent restorations within 60 days (average 31 days). Clinical and radiographic follow-up examinations were performed annually for at least 3 years (mean 55 months). An aesthetic index was used to evaluate the soft tissues adjacent to the prosthetic restorations. No implant was lost during the observation period, giving a survival rate of 100%. Bone level changes during the observation period were minimal, with a mean marginal bone loss of 0.3 ± 0.9 mm around the delayed implants and a mean marginal bone gain of 0.3 ± 1.4 mm around the immediate implants (p = .0036). The frequency distribution of bone level revealed that 85% of implants placed in fresh extraction sockets and 84% of implants in healed bone did not show any loss of bone level during follow-up (p = NS). Soft tissue complications were observed at two immediate implant sites in one patient. The remaining 180 implants received the highest aesthetic score. Moreover, no signs of peri-implant purulent infection or aggressive bone loss were found during the follow-up period. Early loading of fluoridated implants with permanent constructions appears to be a viable therapy for implants placed immediately in extraction sites and in healed bone. © 2014 Wiley Periodicals, Inc.

Immediate breast reconstruction with skin graft is still little mentioned in the literature. Follow-up studies regarding the technique aspects are particularly scarce. The objective was to detail immediate breast reconstruction using autologous skin graft. Patients (n = 49) who underwent mastectomies and autologous immediate breast reconstruction with skin graft associated with a breast implant at A. C. Camargo Hospital (São Paulo, Brazil) between January 2007 and July 2010 were included. Information on clinical data, technique details and clinical outcome were prospectively collected. Following mastectomy, the autologous full-thickness skin graft was obtained through an inframammary fold incision along the contralateral breast in most patients. The skin graft was placed on the surface of the pectoralis major muscle after adjustments to conform to the mastectomy defect. A minimum of 10-month follow-up period was established. Patients' age ranged from 35 to 55 years and all received a silicone gel textured surface implant to obtain the necessary breast mound. The mean surgical time was 45 min, and the mean amount of skin resection was 4.5 cm in the largest diameter. Follow-up ranged from 10 to 35 months (median 23). All patients had silicone-gel textured surface implants to perform the breast mound reconstruction. No complications were observed in 87.8% of reconstructions. Forty-six patients (94%) had no complaints about the donor-site aesthetics. The result was a breast mound with a central ellipse of healed skin graft. Three (6%) poor results were observed. Thirty-six patients (67%) reported the results as good or very good. Our results lead us to conclude that autologous skin graft provided a reliable option in immediate breast reconstruction to skin-sparing mastectomy defects. The technique accomplished a single-stage implant breast reconstruction when there is inadequate skin coverage. Copyright © 2011 British Association of Plastic, Reconstructive and

Offenders' risk-taking attitude inside and outside the prison walls.

Gummerum, Michaela; Hanoch, Yaniv; Rolison, Jonathan J

2014-10-01

It has long been assumed that risk taking is closely associated with criminal behavior. One reason for placing criminals behind bars--aside from punishment and protecting the public--is to prevent them from engaging in further risky criminal activities. Limited attention has been paid to whether being inside or outside prison affects offenders' risk-taking behaviors and attitudes. We compared risk-taking behaviors and attitudes in five risk domains (ethical, financial, health/safety, recreational, social) among 75 incarcerated offenders (i.e., offenders who are currently in prison) and 45 ex-offenders (i.e., offenders who have just been released from prison). Ex-offenders reported higher likelihood of engaging in risky behavior, driven largely by a willingness to take more risks in the recreational and ethical domains. Benefits attributed to risk taking as well as risk perception did not differ between incarcerated and ex-offenders, indicating that the opportunity to take risks might underlie behavioral risk intentions. Our results also indicate that risk-taking activities are better predicted by the expected benefits rather than by risk perception, aside from the health/safety domain. These results highlight the importance of studying the person and the environment and examining risk taking in a number of content domains. © 2014 Society for Risk Analysis.

Multivariate statistical monitoring as applied to clean-in-place (CIP) and steam-in-place (SIP) operations in biopharmaceutical manufacturing.

Multivariate statistical process monitoring (MSPM) is becoming increasingly utilized to further enhance process monitoring in the biopharmaceutical industry. MSPM can play a critical role when there are many measurements and these measurements are highly correlated, as is typical for many biopharmaceutical operations. Specifically, for processes such as cleaning-in-place (CIP) and steaming-in-place (SIP, also known as sterilization-in-place), control systems typically oversee the execution of the cycles, and verification of the outcome is based on offline assays. These offline assays add to delays and corrective actions may require additional setup times. Moreover, this conventional approach does not take interactive effects of process variables into account and cycle optimization opportunities as well as salient trends in the process may be missed. Therefore, more proactive and holistic online continued verification approaches are desirable. This article demonstrates the application of real-time MSPM to processes such as CIP and SIP with industrial examples. The proposed approach has significant potential for facilitating enhanced continuous verification, improved process understanding, abnormal situation detection, and predictive monitoring, as applied to CIP and SIP operations. © 2014 American Institute of Chemical Engineers.

To compare the sequential healing at implants installed in a healed alveolar bony ridge or immediately after tooth extraction without functional load. In the mandible of 12 dogs, the mesial roots of the first molars were endodontically treated, the tooth hemisected, and the distal roots extracted. After 3 months, the mesial roots of the fourth premolars were endodontically treated, the tooth hemisected, and the distal roots extracted in one side of the mandible. Implants were placed immediately into extraction sockets (IPIES) of the fourth premolar and in the healed sites in the molar regions. Healing abutments were placed, and the flaps were sutured to allow a non-submerged healing. The time of surgery and of sacrifices were planned in such a way to obtain biopsies representing the healing after 1 and 2 weeks and 1 and 3 months, respectively. Ground sections were prepared for histological evaluation of tissues components on the implant surface and the coronal termination level of osseointegration (M-B). New bone apposition on the implant surface was slightly higher at the healed compared to the IPIES sites, being 7.4% and 4.1% after 1 week, and 67.3% and 65.3% after 3 months, respectively. Old bone was progressively resorbed, from 27.0% and 21.9% after 1 week, to 2.5% and 2.0% after 3 months, at healed and IPIES sites, respectively. M-B was 1.4 mm and 2.6 mm after 1 week, 1.2 mm and 1.2 mm after 3 months, at healed and IPIES sites, respectively. Similar patterns of sequential osseointegration were found at implants installed in healed alveolar bone or in alveolar sockets immediately after tooth extraction. The coronal termination level of osseointegration, that was different after 1 week, was found similar at the 3-month observation. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

2015-01-01

Background The aims and objectives of this study were placement of implants in freshly extracted sockets of anterior teeth and to evaluate the implant stability, peri-implant radiolucency and gingival inflammation around implant over a short period of 30 months. Materials and Methods A total of 12 patients (8 male and 4 female), ranging in the age from 20 to 50 years, from March 2007 to June 2007, were evaluated for immediate implant placement into 22 fresh extraction sockets. Only maxillary and mandibular anterior teeth/roots (central incisors, lateral incisors and canines) were considered for replacement with implants. One piece implant with integrated abutment and integrated surface, non-submerged, threaded and tapered at apical 5 mm, sand-blasted and acid etched surfaced implants (HI-TEC TRX-OP Implants of Life Care Company) were used. Results The mobility was not present in any of the implants at all the follow up visits. There were 2 implants at 6 month, 1 implant at 12 month, 1 implant at 18 month visits, showing peri-implant radiolucency at some sites at bone to implant contact site. Severe gingival inflammation was not observed in any of the implant site. At every follow-up visit, every implant met the criteria of success and none was found to be failed over a 30 months duration i.e. 100% success rate was achieved by implants in immediate extraction socket. Conclusion The success rate of implant survival in this study was found 100%. These implants have fulfilled all the criteria of implant success and based on the defined criteria, the success rate of implants placed in immediate extraction sockets of anterior teeth compared favorably with the conventional implants. The early results of the present study showed that high survival rates with the implants in immediate extraction sockets can be achieved. PMID:26266220

Shaarawy, Mohammed A; Aboelross, Ehab M

2013-06-01

This study was carried out to evaluate the effect of varying implant position in immediately loaded implant-supported mandibular overdentures on peri-implant bone density, muscle activity, and patient satisfaction. Fourteen completely edentulous patients were selected for the study. After complete denture construction, patients were divided into 2 equal groups. Four dental implants were installed bilaterally in the interforaminal region in the first group, while in the second group, 4 dental implants were inserted bilaterally: 2 in the interforaminal region and 2 in the first molar area. Immediately after suturing, telescopic abutments were screwed to the implants, and the retaining caps were picked up into the fitting surface of the lower denture, which was delivered to the patient. Patients were recalled for radiographic bone density evaluation just after denture delivery and then at 3, 6, and 12 months thereafter. Muscle activities of masseter and temporalis muscles as well as patient satisfaction were also evaluated. The results of the study showed a high success rate approximating 98.2% of the immediately loaded implants. The electromyographic (EMG) records of both muscles in group 1 were significantly higher during chewing hard food after 3 months compared with group 2 (P < .05). Bone density changes were comparable in the 2 groups except at the end of the follow-up period, when group 2 showed a significant increase in peri-implant bone density values of the posteriorly placed implants compared with group 1 (P < .05). From the results of this study, it may be concluded that wide distribution of immediately loaded implants used for supporting mandibular overdentures through posterior placement beyond the interforaminal area results in a favorable response in terms of increased peri-implant bone density as well as decreased EMG activity of masseter and temporalis muscles.

From DRGs to deregulation: New Jersey takes the road less traveled.

Following a 1992 court ruling that declared New Jersey's system of financing uncompensated care unconstitutional, the state radically changed its 12-year-old hospital payment system that pioneered the use of diagnostic-related groups (DRGs). In its place, New Jersey lawmakers approved a package of reforms that lets hospitals set their own charges and collect bad debts, uses the state's unemployment insurance trust fund to pay for charity care, and reforms the individual and small group insurance markets. Immediate results of the law include new subsidies for inner-city hospitals, lower bond ratings, and hospital layoffs.

2017-01-01

To understand the most important steps required to implement immediate postpartum long-acting reversible contraception (LARC) programs in different Georgia hospitals and the barriers to implementing such a program. This was a qualitative study. We interviewed 32 key personnel from 10 Georgia hospitals working to establish immediate postpartum LARC programs. Data were analyzed using directed qualitative content analysis principles. We used the Stages of Implementation to organize participant-identified key steps for immediate postpartum LARC into an implementation guide. We compared this guide to hospitals' implementation experiences. At the completion of the study, LARC was available for immediate postpartum placement at 7 of 10 study hospitals. Participants identified common themes for the implementation experience: team member identification and ongoing communication, payer preparedness challenges, interdependent department-specific tasks, and piloting with continuing improvements. Participants expressed a need for anticipatory guidance throughout the process. Key first steps to immediate postpartum LARC program implementation were identifying project champions, creating an implementation team that included all relevant departments, obtaining financial reassurance, and ensuring hospital administration awareness of the project. Potential barriers included lack of knowledge about immediate postpartum LARC, financial concerns, and competing clinical and administrative priorities. Hospitals that were successful at implementing immediate postpartum LARC programs did so by prioritizing clear communication and multidisciplinary teamwork. Although the implementation guide reflects a comprehensive assessment of the steps to implementing immediate postpartum LARC programs, not all hospitals required every step to succeed. Hospital teams report that implementing immediate postpartum LARC programs involves multiple departments and a number of important steps to consider. A

Mobilization with movement (MWM) has been shown to reduce pain, increase range of motion (ROM) and physical function in a range of different musculoskeletal disorders. Despite this evidence, there is a lack of studies evaluating the effects of MWM for hip osteoarthritis (OA). To determine the immediate effects of MWM on pain, ROM and functional performance in patients with hip OA. Randomized controlled trial with immediate follow-up. Forty consenting patients (mean age 78 ± 6 years; 54% female) satisfied the eligibility criteria. All participants completed the study. Two forms of MWM techniques (n = 20) or a simulated MWM (sham) (n = 20) were applied. pain recorded by numerical rating scale (NRS). hip flexion and internal rotation ROM, and physical performance (timed up and go, sit to stand, and 40 m self placed walk test) were assessed before and after the intervention. For the MWM group, pain decreased by 2 points on the NRS, hip flexion increased by 12.2°, internal rotation by 4.4°, and functional tests were also improved with clinically relevant effects following the MWM. There were no significant changes in the sham group for any outcome variable. Pain, hip flexion ROM and physical performance immediately improved after the application of MWM in elderly patients suffering hip OA. The observed immediate changes were of clinical relevance. Future studies are required to determine the long-term effects of this intervention. Copyright © 2015 Elsevier Ltd. All rights reserved.

The aim of this animal study was to compare the effects of narrow, concave-straight and wide anatomic healing abutments on changes to soft tissues and crestal bone levels around implants immediately placed into extraction sockets in foxhound dogs. Forty-eight titanium implants (Bredent Medical GMBH, Germany) of the same dimensions were placed in six foxhound dogs. They were divided into two groups (n = 24): test (implants with anatomic abutment) and control (implants with concave-straight abutment). The implants were inserted randomly in the post extraction sockets of P2 , P3 , P4, and M1 bilaterally in six dogs. After eight and twelve weeks, the animals were sacrificed and samples extracted containing the implants and the surrounding soft and hard tissues. Soft tissue and crestal bone loss (CBL) were evaluated by histology and histomorphometry. All implants were clinically and histologically osseointegrated. Healing patterns were examined microscopically at eight and twelve weeks. After eight and twelve weeks, for hard tissues, the distance from the implant shoulder to the first bone-to-implant contact (IS-C) was higher for control group in the lingual aspect with statistical significance (P < 0.05). For soft tissues (STL), the distance from the top of the peri-implant mucosa to the apical portion of the junction epithelium (PM-Je) was significantly less on the lingual aspect in the test group (with wider abutment) at eight and twelve weeks (P < 0.05). The distance from the top of the apical portion of the junction epithelium to the first bone-to-implant contact (Je-C) was significantly higher in the test group (wider abutment) in the lingual aspect at eight and twelve weeks (P < 0.05). There was no connective tissue contact with any abutment surface. Within the limitations of this animal study, anatomic healing abutments protect soft and hard tissues and reduce crestal bone resorption compared with concave-straight healing abutments. © 2014 John Wiley

Baclofen facilitates the extinction of methamphetamine-induced conditioned place preference in rats

Voigt, Robin M.; Herrold, Amy A.; Napier, T. Celeste

2011-01-01

The powerful, long-lasting association between the rewarding effects of a drug and contextual cues associated with drug administration can be studied using conditioned place preference (CPP). The GABAB receptor agonist baclofen facilitates the extinction of morphine-induced CPP in mice. The current study extended this work by determining if baclofen could enhance the extinction of methamphetamine (Meth) CPP. CPP was established using a six day conditioning protocol wherein Meth-pairings were alternated with saline-pairings. Rats were subsequently administered baclofen (2mg/kg i.p. or vehicle) immediately after each daily forced extinction session, which consisted of a saline injection immediately prior to being placed into the previously Meth- or saline-paired chamber. One extinction training cycle, consisted of six once-daily forced extinction sessions, mimicking the alternating procedure established during conditioning, followed by a test for preference (Ext test). CPP persisted for at least four extinction cycles in vehicle-treated rats. In contrast, CPP was inhibited following a single extinction training cycle. These data indicate that Meth-induced CPP was resistant to extinction, but extinction training was rendered effective when the training was combined with baclofen. These findings converge with the prior demonstration of baclofen facilitating the extinction of morphine-induced CPP indicating that GABAB receptor actions are independent of the primary (unconditioned) stimulus (i.e., the opiate or the stimulant) and likely reflect mechanisms engaged by extinction learning processes per se. Thus, baclofen administered in conjunction with extinction training may be of value for addiction therapy regardless of the class of drug being abused. PMID:21463025

The objective of this study was to assess the hard and soft tissue changes following immediate placement and provisional restoration of single-tooth implants in the aesthetic zone. Thirteen patients with immediately placed and restored implants were included in this study. All participating patients underwent the same treatment strategy that involved removal of the failed tooth, flapless surgery, immediate implant placement, and connection of a screw-retained provisional restoration. Three months following implant placement, the temporary crowns were replaced by the definitive restorations. Implant survival rates, and hard and soft tissue changes were measured using periapical X-rays and photographs. The range of the observation period was between 12 and 37 months with a mean period of 23.2 ± 7.6 months. At the time of follow-up, all implants were present with no complications. Radiographic evaluation revealed a mean mesial bone gain of 1.20 ± 1.01 mm and a mean distal bone gain of 0.80 ± 1.14 mm, which reached statistical significance. The mean mid-buccal recession was 0.20 ± 0.78 mm, whereas the mesial and distal papillae height loss was 0.50 ± 1.26 mm and 0.30 ± 0.82 mm, respectively. The changes in the soft tissues did not reach statistical significance. Notwithstanding the limitation of a small sample size, this study shows that immediate implant placement and provisional restoration in the maxillary aesthetic zone can result in favorable treatment outcomes with regards to soft and hard tissues changes over a follow-up period of 23.2 ± 7.6 months. Most clinical trials investigating immediate implant placement and immediate restoration in the maxillary anterior zone have focused on implant survival and implant success, with particular emphasis on radiographically assessed hard tissues changes. However, this study assesses the soft tissue changes associated with this procedure, which is an important area of study

Holstege, Christopher P; Wu, Jeffrey; Baer, Alexander B

2002-06-01

A 16-year-old boy presented to the emergency department with rapidly progressing extremity pain, edema, and ecchymosis after envenomation by a copperhead. Crotalidae polyvalent immune Fab (ovine) (CroFab; FabAV) was infused. Six vials were placed in 250 mL of normal saline solution, and the infusion was gradually increased. Fifty minutes after beginning, the infusion was increased to 640 mL/h. Within minutes of the rate increase, the patient experienced full-body urticaria, facial edema, voice change, and tachycardia.

2011-01-01

This study evaluated the effect of light activation (absence, immediate, or delayed) on conversion kinetics and polymerization stress of three commercial dual-cured resin cements (Enforce, RelyX ARC, and Panavia F). Degree of conversion (DC) was monitored for 30 minutes using real-time near–Fourier transform infrared spectroscopy. The cement was mixed, placed on the spectrometer sample holder, and light activated either immediately or after five minutes (delayed light activation). When no light activation was performed, the materials were protected from light exposure (control). DC was evaluated at five and 30 minutes postmixture. Maximum rates of polymerization (Rp(max)) were obtained from the first derivative of the DC vs time curve. Polymerization stress was monitored for 30 minutes in 1-mm-thick specimens inserted between two cylinders attached to a universal testing machine. Data were submitted to analysis of variance/Tukey tests (α=0.05). Immediate light activation promoted the highest DC at five minutes. At 30 minutes, only RelyX ARC did not present a significant difference in DC between activation modes. Enforce and Panavia F presented higher Rp(max) for immediate and delayed light-activation, respectively. RelyX ARC showed similar Rp(max) for all activation modes. The absence of light activation resulted in the lowest stress followed by delayed light activation, while immediate light activation led to the highest values. RelyX ARC showed higher stress than Enforce, while the stress of Panavia F was similar to that of the others. Delayed light activation reduced the polymerization stress of the resin cements tested without jeopardizing DC.

This review aimed to investigate the feasibility of immediate implant placement in infected extraction sockets. We performed electronic and manual searches up to March 2017 to obtain data from randomized controlled trials (RCTs) and nonrandomized controlled clinical trials (CCTs). Using a fixed-effects model to assess the difference in survival rate (primary outcome), we evaluated the risk difference for immediate implant placement in infected and non-infected sites. We estimated the weighted mean differences (WMDs) of the change in marginal bone loss (MBL), probing depth (PD), modified bleeding index (mBI), marginal gingival level (MGL) and width of keratinized gingiva (WKG) at baseline and latest follow-up. In total, five studies (0 RCT, five CCTs) were included in the systematic review and three studies were included in the meta-analysis. The risk difference for immediate implant placement in an infected extraction socket compared with that in a non-infected socket was -0.02. WMDs for MBL, PD, mBI, MGL and WKG between the two groups were 0.32, 0.12, 0.07, -0.06, 0.20 and 0.51, respectively. No statistical differences were observed between the two groups, except for the change in WKG. Implants can be placed in infected extraction sockets after thorough socket debridement. For aesthetics, WKG should be considered when performing immediate implant placement in infected sites.

[Risk-taking in adolescence: A neuroeconomics approach].

PubMed

Barbalat, G; Domenech, P; Vernet, M; Fourneret, P

2010-04-01

adolescents' decision-making biases is temporality. It has been shown that adolescents favor immediate over delayed prospects, reflecting how future consequences of their decisions are heavily discounted. For example, adolescents can fail in projecting the future benefits of having safe sex - and thereby avoiding the risk of sexually transmitted disease or pregnancy - being more interested in the immediate reward of having romantic uninterrupted sexual intercourse. This impairment in inhibiting the choice of the early alternative could be related to the hypofunctionality of the lateral prefrontal cortex. Importantly, these three biases in the evaluation of decisions by adolescents may be related to the maturation of two neuronal systems. On the one hand, the early reorganization of dopaminergic neurons in the motivational system, due to the brutal secretion of sex hormones (mostly estrogens, testosterone and oxytocin) at the beginning of puberty, impels adolescents toward thrill seeking. On the other hand, the slow maturation of the cognitive control system, mostly exerted by the prefrontal cortex, implies that these impulses cannot be appropriately regulated. Two important neurodevelopmental mechanisms are thought to play a key role in the genesis of risk-taking behaviors in adolescence: the brutal secretion of sex hormones at the beginning of puberty and the delayed maturation of cognitive control. As such, these behaviors can be considered as inevitable, even if other factors, like sex, heredity and precariousness, can enhance their frequency. The implications of these conclusions for the prevention of risk-taking behaviors in adolescence are discussed. 2009 L'Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.

Flow cytometry for immediate follow-up of drinking water networks after maintenance.

Drinking water networks need maintenance every once in a while, either planned interventions or emergency repairs. When this involves opening of the water pipes, precautionary measures need to be taken to avoid contamination of the drinking water at all time. Drinking water suppliers routinely apply plating for faecal indicator organisms as quality control in such a situation. However, this takes at least 21 h of waiting time, which can be crucial when dealing with major supply pipes. A combination of flow cytometric (FCM) bacterial cell counts with FCM fingerprinting techniques is proposed in this study as a fast and sensitive additional technique. In three full scale situations, major supply pipes with 400-1050 mm diameter were emptied for maintenance, shock-chlorinated and flushed with large amounts of clean drinking water before taking back in operation. FCM measurements of the discharged flushing water revealed fast lowering and stabilizing bacterial concentrations once flushing is initiated. Immediate comparison with clean reference drinking water used for flushing was done, and the moment when both waters had similar bacterial concentrations was considered as the endpoint of the necessary flushing works. This was usually after 2-4 h of flushing. FCM fingerprinting, based on both bacteria and FCM background, was used as additional method to verify how similar flushing and reference samples were and yielded similar results. The FCM approved samples were several hours later approved as well by the drinking water supplier after plating and incubation for total Coliforms and Enterococci. These were used as decisive control to set the pipes back in operation. FCM proved to be a more conservative test than plating, yet it yielded immediate results. Application of these FCM methods can therefore avoid long unnecessary waiting times and large drinking water losses. Copyright © 2016 Elsevier Ltd. All rights reserved.

Platelet-Rich Plasma Gel Combined with Bovine-Derived Xenograft for the Treatment of Dehiscence Around Immediately Placed Conventionally Loaded Dental Implants in Humans: Cone Beam Computed Tomography and Three-Dimensional Image Evaluation.

2016-01-01

This study clinically and radiographically investigated the potential of platelet-rich plasma (PRP) gel combined with bovine-derived xenograft to treat dehiscence defects around immediate dental implants. This study was performed on 32 sites from 16 patients who each received an immediate implant for a single tooth replacement at a maxillary anterior or premolar site. Patients were divided into two groups according to the augmented materials used. One group received an immediate implant and filling of defects using a PRP gel plus bovine-derived xenograft. The other group received an immediate implant and filling of defects with a bovine-derived xenograft without PRP gel. Cone beam computed tomography (CBCT) was taken before placement, and at 6 and 12 months postsurgery. Both treatment procedures resulted in significant improvements for the primary outcome regarding bone fill, as well as the marginal bone level. In addition, statistically significant differences were found in the bone density for the combined therapy compared with sites treated with bovine-derived xenografts alone (P ≤ .01). Autogenous PRP gel combined with bovine-derived xenograft demonstrated superiority to the bovine-derived xenograft alone, which suggested that it could be successfully applicable for the treatment of dehiscence around an immediate dental implant. Moreover, CBCT can be used to measure dehiscence and to assess bone thickness along the implant.

Patient-centred outcomes are being given great attention by the dental scientific community. The Oral Health Impact Profile -14 questionnaire (OHIP-14) has been introduced to address patients' success criteria when describing the impact of oral rehabilitations on quality of life (OHrQoL). Thirty-five patients wearing a full-arch implant-prosthesis being in place between 4 and 6 years before this analysis were considered eligible and then enrolled in the present retrospective study. According to their prosthetic anamnesis, two groups were defined: delayed loading group (IL-group) and immediate loading group (IL-group). At the moment of analysis, clinical and radiographic parameters were collected, and patients were asked to complete the Oral Health Impact Profile -14 questionnaire (OHIP-14) in order to measure their OHrQoL. Independent t-test showed total OHIP-14 scores to be not significantly different between groups; however, the domains "Functional limitation" and "physical disability" resulted significantly higher in patients within the DL-group. On the contrary, social disability was higher in the IL-group. When the comparison was performed taking sex into account, no significant differences between groups were highlighted. Instead, the stratification for years of follow-up led to significant evidences. When the follow-up was shorter (less-than-5 years), the functional limitation reported scores were higher. Within the limitations of this study, the analysis supports the absence of significant differences between immediate loading and delayed loading full-arch protocol in term of clinical, radiological parameters and OHrQoL.

An ex post facto evaluation framework for place-based police interventions.

PubMed

Braga, Anthony A; Hureau, David M; Papachristos, Andrew V

2011-12-01

A small but growing body of research evidence suggests that place-based police interventions generate significant crime control gains. While place-based policing strategies have been adopted by a majority of U.S. police departments, very few agencies make a priori commitments to rigorous evaluations. Recent methodological developments were applied to conduct a rigorous ex post facto evaluation of the Boston Police Department's Safe Street Team (SST) hot spots policing program. A nonrandomized quasi-experimental design was used to evaluate the violent crime control benefits of the SST program at treated street segments and intersections relative to untreated street segments and intersections. Propensity score matching techniques were used to identify comparison places in Boston. Growth curve regression models were used to analyze violent crime trends at treatment places relative to control places. UNITS OF ANALYSIS: Using computerized mapping and database software, a micro-level place database of violent index crimes at all street segments and intersections in Boston was created. Yearly counts of violent index crimes between 2000 and 2009 at the treatment and comparison street segments and intersections served as the key outcome measure. The SST program was associated with a statistically significant reduction in violent index crimes at the treatment places relative to the comparison places without displacing crime into proximate areas. To overcome the challenges of evaluation in real-world settings, evaluators need to continuously develop innovative approaches that take advantage of new theoretical and methodological approaches.

'It is only a pinprick': (or is it?): childhood vaccinations in general practice as 'matter out of place'.

PubMed

Elverdam, Beth

2011-12-01

The analysis presented in this paper is part of a larger study, the aim of which is to describe the GPs' everyday taken-for-granted working life. The study is based on multi-sited anthropological fieldwork in Danish general practices. This paper analyses consultations where children are vaccinated and the analysis shows the way these consultations differ from other consultations in relation to flow and communication. Neither parents nor doctors question the value of the vaccination, but the manner in which they talk about it and handle it in the flow of the consultation points to them experiencing it as being problematic. Taking inspiration from Mary Douglas' theory on cultural classification the injection is interpreted as 'matter out of place'. The analysis identifies the infliction of pain and the discomfort this brings to the doctor and the parent as problematic as well as a breach of the doctor-patient relationship. The aim of vaccination is to prevent potential diseases in the future, but its function in the consultation, besides being fulfilment of national guidelines, is not immediately apparent. It has no real function in the consultation and this makes it problematic in the present, causing the ambiguity that both doctors and parents express.

Avoidance of plants unsuitable for the symbiotic fungus in leaf-cutting ants: Learning can take place entirely at the colony dump.

PubMed

Arenas, Andrés; Roces, Flavio

2017-01-01

Plants initially accepted by foraging leaf-cutting ants are later avoided if they prove unsuitable for their symbiotic fungus. Plant avoidance is mediated by the waste produced in the fungus garden soon after the incorporation of the unsuitable leaves, as foragers can learn plant odors and cues from the damaged fungus that are both present in the recently produced waste particles. We asked whether avoidance learning of plants unsuitable for the symbiotic fungus can take place entirely at the colony dump. In order to investigate whether cues available in the waste chamber induce plant avoidance in naïve subcolonies, we exchanged the waste produced by subcolonies fed either fungicide-treated privet leaves or untreated leaves and measured the acceptance of untreated privet leaves before and after the exchange of waste. Second, we evaluated whether foragers could perceive the avoidance cues directly at the dump by quantifying the visits of labeled foragers to the waste chamber. Finally, we asked whether foragers learn to specifically avoid untreated leaves of a plant after a confinement over 3 hours in the dump of subcolonies that were previously fed fungicide-treated leaves of that species. After the exchange of the waste chambers, workers from subcolonies that had access to waste from fungicide-treated privet leaves learned to avoid that plant. One-third of the labeled foragers visited the dump. Furthermore, naïve foragers learned to avoid a specific, previously unsuitable plant if exposed solely to cues of the dump during confinement. We suggest that cues at the dump enable foragers to predict the unsuitable effects of plants even if they had never been experienced in the fungus garden.

2013-04-01

To measure strains around orthodontic implants upon torque tightening and loading and to assess correlations between factors influencing primary stability. Self-drilling implants were placed into bovine iliac crest blocks after CT assessments. Upon bonding of strain gauges on bone adjacent to the implants, strain measurements were performed using a data acquisition system during torque tightening and 250 g orthodontic force application by elastic chains. The torque required to place straight implants (12.16 N.cm) was higher than 30- to 40-degree angulated implants (9.31 N.cm) (P < 0.05). Cortical bone strain amplitudes of both implant placements were comparable (P > 0.05). Strains during torque tightening of straight (196 με) and tilted (114 με) implants were higher than those obtained during orthodontic loading (20-30 με). Despite the positive and direct relationship found between torque and torque strain output, strong correlations between other parameters could not be detected. Vertically aligned and 30- to 40-degree angulated immediate orthodontic microimplants are associated with low amplitude strains upon torque tightening and orthodontic loading.

Can amorphization take place in nanoscale interconnects?

PubMed

Kumar, S; Joshi, K L; van Duin, A C T; Haque, M A

2012-03-09

The trend of miniaturization has highlighted the problems of heat dissipation and electromigration in nanoelectronic device interconnects, but not amorphization. While amorphization is known to be a high pressure and/or temperature phenomenon, we argue that defect density is the key factor, while temperature and pressure are only the means. For nanoscale interconnects carrying modest current density, large vacancy concentrations may be generated without the necessity of high temperature or pressure due to the large fraction of grain boundaries and triple points. To investigate this hypothesis, we performed in situ transmission electron microscope (TEM) experiments on 200 nm thick (80 nm average grain size) aluminum specimens. Electron diffraction patterns indicate partial amorphization at modest current density of about 10(5) A cm(-2), which is too low to trigger electromigration. Since amorphization results in drastic decrease in mechanical ductility as well as electrical and thermal conductivity, further increase in current density to about 7 × 10(5) A cm(-2) resulted in brittle fracture failure. Our molecular dynamics (MD) simulations predict the formation of amorphous regions in response to large mechanical stresses (due to nanoscale grain size) and excess vacancies at the cathode side of the thin films. The findings of this study suggest that amorphization can precede electromigration and thereby play a vital role in the reliability of micro/nanoelectronic devices.

Decay Theory of Immediate Memory: From Brown (1958) to Today (2014)

PubMed Central

Ricker, Timothy J.; Vergauwe, Evie; Cowan, Nelson

2014-01-01

This work takes a historical approach to discussing Brown’s (1958) paper, “Some Tests of the Decay Theory of Immediate Memory”. This work was and continues to be extremely influential in the field of forgetting over the short-term. Its primary importance is in establishing a theoretical basis to consider a process of fundamental importance, memory decay. Brown (1958) established that time-based explanations of forgetting can account for both memory capacity and forgetting of information over short periods of time. We discuss this view both in the context of the intellectual climate at the time of the paper’s publication and in the context of the modern intellectual climate. The overarching theme we observe is that decay is as controversial now as it was in the 1950s and 1960s. PMID:24853316

Sense of place and place identity: review of neuroscientific evidence.

Lengen, Charis; Kistemann, Thomas

2012-09-01

The aim of this review is to bring the phenomenological sense of place approach together with current results from neuroscience. We searched in neuroscientific literature for ten dimensions which were beforehand identified to be important in a phenomenological sense of place/place identity model: behaviour, body, emotion, attention, perception, memory, orientation, spirituality, meaning/value and culture/sociality. Neuroscience has identified many neurobiological correlates of phenomenological observations concerning sense of place. The human brain comprises specific and specialised structures and processes to perceive, memorise, link, assess and use spatial information. Specific parts (hippocampus, entorhinal, parahippocampal and parietal cortex), subregions (parahippocampal place area, lingual landmark area), and cells (place cells, grid cells, border cells, head direction cells) have been identified, their specific function could be understood and their interaction traced. Neuroscience has provided evidence that place constitutes a distinct dimension in neuronal processing. This reinforces the phenomenological argumentation of human geography and environmental psychology. Copyright © 2012 Elsevier Ltd. All rights reserved.

Immediate effects of Tuina techniques on working-related musculoskeletal disorder of professional orchestra musicians.

Sousa, Cláudia Maria; Moreira, Luis; Coimbra, Daniela; Machado, Jorge; Greten, Henry J

2015-07-01

Musicians are a prone group to suffer from working-related musculoskeletal disorder (WRMD). Conventional solutions to control musculoskeletal pain include pharmacological treatment and rehabilitation programs but their efficiency is sometimes disappointing. The aim of this research is to study the immediate effects of Tuina techniques on WRMD of professional orchestra musicians from the north of Portugal. We performed a prospective, controlled, single-blinded, randomized study. Professional orchestra musicians with a diagnosis of WRMD were randomly distributed into the experimental group (n=39) and the control group (n=30). During an individual interview, Chinese diagnosis took place and treatment points were chosen. Real acupoints were treated by Tuina techniques into the experimental group and non-specific skin points were treated into the control group. Pain was measured by verbal numerical scale before and immediately after intervention. After one treatment session, pain was reduced in 91.8% of the cases for the experimental group and 7.9% for the control group. Although results showed that Tuina techniques are effectively reducing WRMD in professional orchestra musicians of the north of Portugal, further investigations with stronger measurements, double-blinding designs and bigger simple sizes are needed.

Lombardo, Giorgio; Corrocher, Giovanni; Pighi, Jacopo; Mascellaro, Anna; Marincola, Mauro; Nocini, Per Francesco

2016-06-01

The purpose of this study was to evaluate the esthetic outcome of single-tooth locking taper connection implants placed in the anterior maxilla following a postextractive nonfunctional loading protocol. This preliminary clinical study involving 16 patients evaluated the results of 21 implants placed in areas with high esthetic value. For each implant the pink esthetic score, white esthetic score, cumulative survival rate, and health status of peri-implant tissues were evaluated. The cumulative survival rate was 100% 2 years after prosthetic loading, and the mean total pink esthetic score/white esthetic score was 16.9 ± 1.14 on a maximum value of 20. There was excellent plaque control in all patients, and inflammation indices were within the norm. Within the limits of this study, this immediate nonfunctional loading protocol seems to be a successful procedure esthetically and for the maintenance of peri-implant soft tissues.

A place-based model of local activity spaces: individual place exposure and characteristics

NASA Astrophysics Data System (ADS)

Hasanzadeh, Kamyar; Laatikainen, Tiina; Kyttä, Marketta

2018-01-01

Researchers for long have hypothesized relationships between mobility, urban context, and health. Despite the ample amount of discussions, the empirical findings corroborating such associations remain to be marginal in the literature. It is growingly believed that the weakness of the observed associations can be largely explained by the common misspecification of the geographical context. Researchers coming from different fields have developed a wide range of methods for estimating the extents of these geographical contexts. In this article, we argue that no single approach yet has sufficiently been capable of capturing the complexity of human mobility patterns. Subsequently, we discuss that reaching a better understanding of individual activity spaces can be possible through a spatially sensitive estimation of place exposure. Following this discussion, we take an integrative person and place-based approach to create an individualized residential exposure model (IREM) to estimate the local activity spaces (LAS) of the individuals. This model is created using data collected through public participation GIS. Following a brief comparison of IREM with other commonly used LAS models, the article continues by presenting an empirical study of aging citizens in Helsinki area to demonstrate the usability of the proposed framework. In this study, we identify the main dimensions of LASs and seek their associations with socio-demographic characteristics of individuals and their location in the region. The promising results from comparisons and the interesting findings from the empirical part suggest both a methodological and conceptual improvement in capturing the complexity of local activity spaces.

Nowadays, aesthetic appearance is receiving more and more attention from clinicians and patients. Therefore, it is of paramount importance for the surgeon to maintain or to improve the quality and the stability of the soft tissue-implant interface. The scientific literature supports the idea that the immediate placement and provisionalization of endosseus implants and abutments can indeed offer additional clinical control over the peri-implant tissue architecture. On this basis, this prospective study aims to evaluate the changes in soft tissues around immediately loaded dental implants in full-arch rehabilitations, over a period of 3 months. Fifteen subjects were treated for immediate full-arch rehabilitations. Following implant placement, provisional rehabilitations made of bisphenol-A-glycidyldimethacrylate (BIS-GMA) and resin were placed. All records were made using a periodontal probe. The facial soft-tissue level was measured evaluating the distance between the soft-tissue margin and the incisal edge of the crown. Moreover, papilla levels were measured at the mesial and distal sites from a reference line connecting the occlusal edge of the crowns. The average value at the mesial site was -0.035 mm (±1, median 0 mm), while at the midfacial site, it was 0 mm (±0.76, median 0 mm) and at the distal site, -0.05 mm (±0.92, median 0 mm). The plaque score index showed a reduction during the follow-up period. Our data indicate that no differences at the midfacial point were detectable over the observation period. This is in agreement with several studies; it is plausible that these results are linked to a correct position of the implant in the alveolar socket. Moreover, comparing our results with what has been reported by other authors, it is surprising that while other studies highlight that papilla loss at the mesial and distal aspect is an expected consequence of immediate implant restorations, our data do not show any changes.

Modeling place field activity with hierarchical slow feature analysis

What are the computational laws of hippocampal activity? In this paper we argue for the slowness principle as a fundamental processing paradigm behind hippocampal place cell firing. We present six different studies from the experimental literature, performed with real-life rats, that we replicated in computer simulations. Each of the chosen studies allows rodents to develop stable place fields and then examines a distinct property of the established spatial encoding: adaptation to cue relocation and removal; directional dependent firing in the linear track and open field; and morphing and scaling the environment itself. Simulations are based on a hierarchical Slow Feature Analysis (SFA) network topped by a principal component analysis (ICA) output layer. The slowness principle is shown to account for the main findings of the presented experimental studies. The SFA network generates its responses using raw visual input only, which adds to its biological plausibility but requires experiments performed in light conditions. Future iterations of the model will thus have to incorporate additional information, such as path integration and grid cell activity, in order to be able to also replicate studies that take place during darkness.

Using a Flying Thing in the Sky to See How Much Water is in the Cover of Tiny Ice Pieces in the High Places

2016-12-01

Groups of tiny ice pieces fall from the sky in the cold times and cover the high places. Later, the tiny ice pieces become water that moves to the lower places, where people can use it for drinking and stuff. The time when the tiny ice pieces turn to water is controlled by the sun. New tiny ice pieces from the sky, which are very white and don't take up much sun, group up and grow tall. When they become dark from getting old and large, and from getting covered in tiny dark bits from the sky, they take up more sun and turn to water. The more tiny dark bits, the faster they become water. Using a flying thing over the high places we can see how much water will come from the cover of tiny ice pieces by using ground looking things to see how tall it is, and and when it will become water by using picture taking things to see how much sun is taken up. The low places are happy to know how much water is in the high places.

2D FEA of evaluation of micromovements and stresses at bone-implant interface in immediately loaded tapered implants in the posterior maxilla

Aim: The aim of the study is to evaluate the influence implant length on stress distribution at bone implant interface in single immediately loaded implants when placed in D4 bone quality. Materials and Methods: A 2-dimensional finite element models were developed to simulate two types of implant designs, standard 3.75 mm–diameter tapered body implants of 6 and 10 mm lengths. The implants were placed in D4 bone quality with a cortical bone thickness of 0.5 mm. The implant design incorporated microthreads at the crestal part and the rest of the implant body incorporated Acme threads. The Acme thread form has a 29° thread angle with a thread height half of the pitch; the apex and valley are flat. A 100 N of force was applied vertically and in the oblique direction (at an angle of 45°) to the long axis of the implants. The respective material properties were assigned. Micro-movements and stresses at the bone implant interface were evaluated. Results: The results of total deformation (micro-movement) and Von mises stress were found to be lower for tapered long implant (10 mm) than short implant (6 mm) while using both vertical as well as oblique loading. Conclusion: Short implants can be successfully placed in poor bone quality under immediate loading protocol. The novel approach of the combination of microthreads at the crestal portion and acme threads for body portion of implant fixture gave promising results. PMID:24174759

The aim of this prospective cohort study was to assess the ten-year performance of the condensing thread, self-tapping apex and internal hexagonal connection XiVE implant supporting partial fixed prostheses placed with an immediate restoration approach. All patients received a fixed two- to four-unit partial provisional restoration supported by immediately loaded implants. The final gold alloy/ceramic restorations were cemented approximately 28 weeks after implant insertion. Marginal bone level, pocket probing depth and percentage of bleeding on probing, biological or technical complications and any other adverse events were measured annually up to ten years after surgery. The overall success and survival rates at implant level were evaluated following the International Congress of Oral Implantologists (ICOI) Pisa Consensus Conference criteria. Implant placement in post-extractive or healed sites, smoking and a history of periodontal treatment were evaluated to assess whether they had an influence on bone resorption or on implant survival. Of 114 patients, for a total of 284 implants, fulfilled all the inclusion criteria and were enrolled in the study. 78 (27.5%) implants placed in 30 (26.3%) patients were lost to follow-up. Eight of 284 (2.8%) implants failed in 8 of 114 (7.0%) patients: one (12.5% of losses) due to failure to achieve osseointegration and seven (87.5% of losses) due to peri-implantitis. No cluster implant failures were assessed. The failure of the implant caused the failure of the prosthesis due to the strategic position of the implant in four patients. At the final ten-year follow-up, 121 (61.4%) implants exhibited a "full success" status with an optimal health condition, 21 (10.9%) implants scored a "satisfactory survival" condition, while 49 (25.49%) of the implants were classified as "compromised survival" status (Misch et al. 2008). Smoking was found to be statistically associated with "implant failure" (P = 0.010), while no association

Background Women’s preferences for type of maternity caregiver and birth place have gained importance and have been documented in studies reported from the developed world. The purpose of our study was to identify Syrian women’s preferences for birth attendant and place of delivery. Methods Interviews with 500 women living in Damascus and its suburbs were conducted using a pretested structured questionnaire. Women were asked about their preferences for the birth attendant and place of delivery, and an open-ended question asked them to give an explanation for their preferences. We analyzed preferences and their determinants, and also agreement between actual and preferred place of delivery and birth attendant. Results Only a small minority of women (5–10%) had no preference. Most (65.8%) preferred to give birth at the hospital, and 60.4 percent preferred to be attended by doctors compared with midwives (21.2%). More than 85 percent of women preferred the obstetrician to be a female. The actual place of delivery and type of birth attendant did not match the preferred place of delivery and type of birth attendant. Women’s reasons for preferences were a perception of safety and competence, and communication style of caregiver. Conclusions Most women preferred to be delivered by female doctors at a hospital in this population sample in Syria. The findings suggest that proper understanding of women’s preferences is needed, and steps should be taken to enable women to make good choices. Policies about maternity education and services should take into account women’s preferences. PMID:15725201

A note on notes: note taking and containment.

Levine, Howard B

2007-07-01

In extreme situations of massive projective identification, both the analyst and the patient may come to share a fantasy or belief that his or her own psychic reality will be annihilated if the psychic reality of the other is accepted or adopted (Britton 1998). In the example of' Dr. M and his patient, the paradoxical dilemma around note taking had highly specific transference meanings; it was not simply an instance of the generalized human response of distracted attention that Freud (1912) had spoken of, nor was it the destabilization of analytic functioning that I tried to describe in my work with Mr. L. Whether such meanings will always exist in these situations remains a matter to be determined by further clinical experience. In reopening a dialogue about note taking during sessions, I have attempted to move the discussion away from categorical injunctions about what analysis should or should not do, and instead to foster a more nuanced, dynamic, and pair-specific consideration of the analyst's functioning in the immediate context of the analytic relationship. There is, of course, a wide variety of listening styles among analysts, and each analyst's mental functioning may be affected differently by each patient whom the analyst sees. I have raised many questions in the hopes of stimulating an expanded discussion that will allow us to share our experiences and perhaps reach additional conclusions. Further consideration may lead us to decide whether note taking may have very different meanings for other analysts and analyst-patient pairs, and whether it may serve useful functions in addition to the one that I have described.

Toward citizenship science education: what students do to make the world a better place?

With increased focus on sustainability and socioscientific issues, dealing with issues related to citizenship is now seen as an important element of science education. However, in order to make the world a better place, mere understanding about socioscientific issues is not enough. Action must also be taken. In this study, 35 international gifted students-potential scientists-aged 15-19 were interviewed to investigate what they were doing to make the world a better place. The interviews were analyzed using qualitative content analysis with focus on students' actions toward a better world, their rationalizations for such actions, and the role of science in the rationalizations. The analysis shows that students consciously take a wide range of actions, and that they see citizenship as a process of constant self-development. The three categories created to highlight the variation in the ways students take action were personally responsible actions, participatory actions, and preparing for future. Although many students saw that science and scientists play a big role in solving especially the environmental problems, most of them also discussed the structural causes for problems, as well as the interplay of social, economic, and political forces. The results indicate that citizenship science education should take the variety of students' actions into consideration, give students the possibility to take individual and participatory action, as well as give students opportunities to get to know and discuss the ways a career in science or engineering can contribute to saving the world.

Der Einsatz der sozialen Medien im Place Branding. Das Beispiel Allgäu

Kräußlich, Bernhard; Schürholz, Peter

2017-12-01

This article focuses on the opportunities and risks of using social media in place branding. Where local authorities provide their content in the context of a place branding via social media, the users gain attributes of a prosumer, most important of which is the high potential for participating in the actual branding process. This active participation causes a variety of changes compared to a branding process without social media. Thus, a qualitative, a quantitative, as well as a temporal and spatial increase of contact with the brand can be determined, though, by virtue of the anonymity provided by the Internet, it is quite possible that this all takes place covertly. A permanent monitoring of the branding process on the part of the operators has become necessary in order to react quickly to changes. The Allgäu model offers a possible procedure for reacting to the new requirements in social media-sampled place branding.

The effects of perspective-taking on prejudice: the moderating role of self-evaluation.

PubMed

Galinsky, Adam D; Ku, Gillian

2004-05-01

Perspective-taking, by means of creating an overlap between self and other cognitive representations, has been found to effectively decrease stereotyping and ingroup favoritism. In the present investigation, the authors examined the potential moderating role of self-esteem on the effects of perspective-taking on prejudice. In two experiments, it was found that perspective-takers, but not control participants, with temporarily or chronically high self-esteem evaluated an outgroup more positively than perspective-takers with low self-esteem. This finding suggests an irony of perspective-taking: it builds off egocentric biases to improve outgroup evaluations. The discussion focuses on how debiasing intergroup thought is often best accomplished by working through the very processes that produced the bias in the first place.

Esthetic assessment of immediately restored implants combined with GBR and free connective tissue (CT) graft METHODS: A case-control, retrospective study involving 34 patients treated with maxillary anterior single implants, immediately placed and restored. Clinical and esthetic results were analyzed using standard clinical examination and a comprehensive index, comprising pink esthetic and white esthetic scores (PES/WES). The height of the implant crown and the corresponding height of the contralateral tooth crown were measured to identify mucosal recessions. The distance from the mucosal margin to the implant shoulder (DIM) was measured on the master model. Thirty of 34 implants fulfilled the strict success criteria set for dental implants with regard to osseointegration. Success was defined as implants with bone loss not exceeding 1.5 mm during the first year and loosing not more than 0.2 for each successive year. The other four implants were stable but did not meet the bone loss criteria mentioned above and defined as survived implants. Mean PES/WES was 14.44 ± 2.34 (range: 9-20). Mean PES was 7.12 ± 1.89 (range: 1-10). The highest mean values were achieved for the variable of root convexity/soft tissue color and texture (1.71 ± 0.46) whereas the mesial papilla (1.09 ± 0.62) proved to be the least pleasing. The mean WES was 7.32 ± 1.25 (range: 5-10). The difference between IC and contralateral TC was 0.54 mm. The mean value for the facial DIM was 3.82 ± 0.87 mm. An evaluation of soft and hard tissue augmentation in immediately restored immediate implant procedures was employed to obtain stable hard and soft tissues. The combined GBR and CT graft procedure achieved favorable peri-implant soft tissue condition and esthetic results. However, recession and incomplete papillas were frequently observed. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Taking the Risk Out of Risk Assessment

NASA Technical Reports Server (NTRS)

2005-01-01

The ability to understand risks and have the right strategies in place when risky events occur is essential in the workplace. More and more organizations are being confronted with concerns over how to measure their risks or what kind of risks they can take when certain events transpire that could have a negative impact. NASA is one organization that faces these challenges on a daily basis, as effective risk management is critical to the success of its missions especially the Space Shuttle missions. On July 29, 1996, former NASA Administrator Daniel Goldin charged NASA s Office of Safety and Mission Assurance with developing a probabilistic risk assessment (PRA) tool to support decisions on the funding of Space Shuttle upgrades. When issuing the directive, Goldin said, "Since I came to NASA [in 1992], we've spent billions of dollars on Shuttle upgrades without knowing how much they improve safety. I want a tool to help base upgrade decisions on risk." Work on the PRA tool began immediately. The resulting prototype, the Quantitative Risk Assessment System (QRAS) Version 1.0, was jointly developed by NASA s Marshall Space Flight Center, its Office of Safety and Mission Assurance, and researchers at the University of Maryland. QRAS software automatically expands the reliability logic models of systems to evaluate the probability of highly detrimental outcomes occurring in complex systems that are subject to potential accident scenarios. Even in its earliest forms, QRAS was used to begin PRA modeling of the Space Shuttle. In parallel, the development of QRAS continued, with the goal of making it a world-class tool, one that was especially suited to NASA s unique needs. From the beginning, an important conceptual goal in the development of QRAS was for it to help bridge the gap between the professional risk analyst and the design engineer. In the past, only the professional risk analyst could perform, modify, use, and perhaps even adequately understand PRA. NASA wanted

To identify the immediate economic impact of maternal death on rural Chinese households. Results are reported from a study that matched 195 households who had suffered a maternal death to 384 households that experienced a childbirth without maternal death in rural areas of three provinces in China, using quantitative questionnaire to compare differences of direct and indirect costs between two groups. The direct costs of a maternal death were significantly higher than the costs of a childbirth without a maternal death (US$4,119 vs. $370, p<0.001). More than 40% of the direct costs were attributed to funeral expenses. Hospitalization and emergency care expenses were the largest proportion of non-funeral direct costs and were higher in households with maternal death than the comparison group (US$2,248 vs. $305, p<0.001). To cover most of the high direct costs, 44.1% of affected households utilized compensation from hospitals, and the rest affected households (55.9%) utilized borrowing money or taking loans as major source of money to offset direct costs. The median economic burden of the direct (and non-reimbursed) costs of a maternal death was quite high--37.0% of the household's annual income, which was approximately 4 times as high as the threshold for an expense being considered catastrophic. The immediate direct costs of maternal deaths are extremely catastrophic for the rural Chinese households in three provinces studied.

Strategy modulates spatial perspective-taking: evidence for dissociable disembodied and embodied routes

Previous research provides evidence for a dissociable embodied route to spatial perspective-taking that is under strategic control. The present experiment investigated further the influence of strategy on spatial perspective-taking by assessing whether participants may also elect to employ a separable “disembodied” route loading on inhibitory control mechanisms. Participants (N = 92) undertook both the “own body transformation” (OBT) perspective-taking task, requiring speeded spatial judgments made from the perspective of an observed figure, and a control task measuring ability to inhibit spatially compatible responses in the absence of a figure. Perspective-taking performance was found to be related to performance on the response inhibition control task, in that participants who tended to take longer to adopt a new perspective also tended to show a greater elevation in response times when inhibiting spatially compatible responses. This relationship was restricted to those participants reporting that they adopted the perspective of another by reversing left and right whenever confronted with a front-view figure; it was absent in those participants who reported perspective-taking by mentally transforming their spatial orientation to align with that of the figure. Combined with previously published results, these findings complete a double dissociation between embodied and disembodied routes to spatial perspective-taking, implying that spatial perspective-taking is subject to modulation by strategy, and suggesting that embodied routes to perspective-taking may place minimal demands on domain general executive functions.

Immediate or early skin-to-skin contact after a Caesarean section: a review of the literature.

Stevens, Jeni; Schmied, Virginia; Burns, Elaine; Dahlen, Hannah

2014-10-01

The World Health Organization and the United Nations International Children's Emergency Fund recommends that mothers and newborns have skin-to-skin contact immediately after a vaginal birth, and as soon as the mother is alert and responsive after a Caesarean section. Skin-to-skin contact can be defined as placing a naked infant onto the bare chest of the mother. Caesarean birth is known to reduce initiation of breastfeeding, increase the length of time before the first breastfeed, reduce the incidence of exclusive breastfeeding, significantly delay the onset of lactation and increase the likelihood of supplementation. The aim of this review is to evaluate evidence on the facilitation of immediate (within minutes) or early (within 1 h) skin-to-skin contact following Caesarean section for healthy mothers and their healthy term newborns, and identify facilitators, barriers and associated maternal and newborn outcomes. A range of electronic databases were searched for papers reporting research findings published in English between January 2003 and October 2013. Seven papers met the criteria. This review has provided some evidence that with appropriate collaboration skin-to-skin contact during Caesarean surgery can be implemented. Further evidence was provided, albeit limited, that immediate or early skin-to-skin contact after a Caesarean section may increase breastfeeding initiation, decrease time to the first breastfeed, reduce formula supplementation in hospital, increase bonding and maternal satisfaction, maintain the temperature of newborns and reduce newborn stress. © 2014 John Wiley & Sons Ltd.

Meanings of immediate: the practical use of the Patient's Charter in the accident and emergency department.

PubMed

Sbaih, Lynn C

2002-05-01

The publication of the Patient's Charter in Britain enabled patients to have access to a series of documented standards relating to health care provision in a variety of situations. However since its introduction much discussion has taken place as to its application in clinical practice. An initial interest in the accomplishment of routine accident and emergency (A& E) nursing work led to the identification of issues associated with the use of the Patient's Charter standards; particularly those associated with immediate assessment in the A & E department. Data were collected from 60 nurses in five A& E departments and analysed using a multidisciplinary multistage approach. Findings suggest that nurses are expected to juggle the daily tensions produced by the Charter standards, associated with initial assessment, alongside the accomplishment of other aspects of the work dedicated to the safe movement of patients through the system. Tensions are rooted in two particular issues. Firstly, the meanings of immediate assessment continue to remain open to interpretation and therefore difficult to capture and manage. Secondly, the Patient's Charter standards, associated with immediate assessment, deal with one aspect of the work only and yet the accomplishment of A & E work is dependent upon maintaining a perception of order and shape throughout the whole department. Ultimately both issues have an impact on nurses' recognition and management of what they know to be the normal appearances and shape of routine work.

Among the range of therapeutic mediators used with dangerous mental health patients in the unit for dangerous patients in Cadillac, cooking holds an important place. Led by caregivers, this activity has undeniable positive effects for the psychotic and non-psychotic patients taking part. These effects concern notably their capacities for conception, creation, organisation, execution, sensation, collaboration and socialisation. For some patients, it is also the opportunity to take the drama out of handling utensils which they previously used as weapons. As the risk factors are controlled before and during the activity, no dangerous acting out has ever occurred. Copyright © 2015. Published by Elsevier Masson SAS.

OBJECTIVE: To compare the long-term clinical and histologic outcome of immediate autografting of full-thickness burn wounds ablated with a high-power continuous-wave CO2 laser to sharply débrided wounds in a porcine model. SUMMARY BACKGROUND DATA: Continuous-wave CO2 lasers have performed poorly as tools for burn excision because the large amount of thermal damage to viable subeschar tissues precluded successful autografting. However, a new technique, in which a high-power laser is rapidly scanned over the eschar, results in eschar vaporization without significant damage to underlying viable tissues, allowing successful immediate autografting. METHODS: Full-thickness paravertebral burn wounds measuring 36 cm2 were created on 11 farm swine. Wounds were ablated to adipose tissue 48 hours later using either a surgical blade or a 150-Watt continuous-wave CO2 laser deflected by an x-y galvanometric scanner that translated the beam over the tissue surface, removing 200 microm of tissue per scan. Both sites were immediately autografted and serially evaluated clinically and histologically for 180 days. RESULTS: The laser-treated sites were nearly bloodless. The mean residual thermal damage was 0.18+/-0.05 mm. The mean graft take was 96+/-11% in manual sites and 93+/-8% in laser sites. On postoperative day 7, the thickness of granulation tissue at the graft-wound bed interface was greater in laser-debrided sites. By postoperative day 180, the manual and laser sites were histologically identical. Vancouver scar assessment revealed no differences in scarring at postoperative day 180. CONCLUSIONS: Long-term scarring, based on Vancouver scar assessments and histologic evaluation, was equivalent at 6 months in laser-ablated and sharply excised sites. Should this technology become practical, the potential clinical implications include a reduction in surgical blood loss without sacrifice of immediate engraftment rates or long-term outcome.

Seizures after primary intracerebral hemorrhage (PICH) are significant and treatable complications, but the factors predicting immediate, early and late seizures are poorly known. We investigated characteristics and outcome with special reference to occurrence and timing of a first seizure among consecutive subjects with PICH. A population-based study was conducted in Northern Ostrobothnia, Finland, in 1993-2008 that included all patients with a first-ever primary ICH without any prior diagnosis of epilepsy. Immediate (<24h after admission), early (1-14 days) and late (>2 weeks) seizures were considered separately. Out of a total of 935 ICH patients, 51 had immediate, 21 early and 58 late seizures. The patients with seizures were significantly younger than the others and more often had a subcortical hematoma location (p<0.05). Lifestyle factors did not differ between the groups. The risk factors for immediate seizures in multivariable analysis were a low Glasgow coma scale score (GCS) on admission, subcortical location and age inversely (p<0.01). The only independent risk factor for early seizures was subcortical location (p<0.001), whereas subcortical location (p<0.001), age inversely (p<0.01) and hematoma evacuation (p<0.05) independently predicted late seizures. Immediate and early seizures predicted infectious complications (p<0.05). Patients with subcortical hematoma and of younger age are at risk for immediate seizures after primary ICH irrespective of hematoma size. Patients with immediate and early seizures more often had infectious complications. Surgery increases the risk of a late seizure after ICH. Copyright © 2014 Elsevier B.V. All rights reserved.

Targeting condom distribution at high risk places increases condom utilization-evidence from an intervention study in Livingstone, Zambia

PubMed Central

2012-01-01

Background The PLACE-method presumes that targeting HIV preventive activities at high risk places is effective in settings with major epidemics. Livingstone, Zambia, has a major HIV epidemic despite many preventive efforts in the city. A baseline survey conducted in 2005 in places where people meet new sexual partners found high partner turnover and unprotected sex to be common among guests. In addition, there were major gaps in on-site condom availability. This study aimed to assess the impact of a condom distribution and peer education intervention targeting places where people meet new sexual partners on condom use and sexual risk taking among people socializing there. Methods The 2005 baseline survey assessed the presence of HIV preventive activities and sexual risk taking in places where people meet new sexual partners in Livingstone. One township was selected for a non-randomised intervention study on condom distribution and peer education in high risk venues in 2009. The presence of HIV preventive activities in the venues during the intervention was monitored by an external person. The intervention was evaluated after one year with a follow-up survey in the intervention township and a comparison township. In addition, qualitative interviews and focus group discussions were conducted. Results Young people between 17-32 years of age were recruited as peer educators, and 40% were females. Out of 72 persons trained before the intervention, 38 quit, and another 11 had to be recruited. The percentage of venues where condoms were reported to always be available at least doubled in both townships, but was significantly higher in the intervention vs. the control venues in both surveys (84% vs. 33% in the follow-up). There was a reduction in reported sexual risk taking among guests socializing in the venues in both areas, but reporting of recent condom use increased more among people interviewed in the intervention (57% to 84%) than in the control community (55% to 68

This report demonstrates the clinical use of a modified, truly anatomic, root-analogue zirconia implant for immediate replacement of a two-rooted, left first mandibular molar. A 50-year-old female patient with chronic apical periodontitis of the left mandibulary first molar was referred and the tooth was extracted. The mesial root had to be removed surgically due to a root fracture. A truly anatomical, root identical, roughened zirconia implant modified by macro-retentions was manufactured and placed into the extraction socket by tapping 7 days later. After 4 months a composite crown was cemented in place. No complications occurred during the healing period. A good functional and aesthetic result was achieved with minimal bone resorption and soft tissue recession at 30 months follow-up. This report describes the successful clinical use of an immediate, single stage, truly anatomical root-analogue zirconia implant for replacement of a two-rooted tooth. Significant modifications such as macro-retentions yielded primary stability and excellent osseointegration. This novel approach is minimally invasive, respects the underlying anatomy, aids socket prevention, is time- and cost-saving with good patient acceptance as there is no need for bone drilling, sinus lift, bone augmentation or other traumatic procedures.

Long-term collaborative relationships require that any jointly produced resources be shared in mutually satisfactory ways. Prototypically, this sharing involves partners dividing up simultaneously available resources, but sometimes the collaboration makes a resource available to only one individual, and any sharing of resources must take place across repeated instances over time. Here, we show that beginning at 5 years of age, human children stabilize cooperation in such cases by taking turns across instances of obtaining a resource. In contrast, chimpanzees do not take turns in this way, and so their collaboration tends to disintegrate over time. Alternating turns in obtaining a collaboratively produced resource does not necessarily require a prosocial concern for the other, but rather requires only a strategic judgment that partners need incentives to continue collaborating. These results suggest that human beings are adapted for thinking strategically in ways that sustain long-term cooperative relationships and that are absent in their nearest primate relatives. © The Author(s) 2016.

Immediate placement of endosseous implants into the extraction sockets.

Implant by definition "means any object or material, such as an alloplastic substance or other tissue, which is partial or completely inserted into the body for therapeutic, diagnostic, prosthetic, or experimental purpose." The placement of a dental implant in an extraction socket at the time of extraction or explantation is known as immediate implant placement whereas delayed placement of implant signifies the implant placement in edentulous areas where healing has completed with new bone formation after the loss of tooth/teeth. Recent idea goes by "why late when it can be done immediately." There are several advantages of immediate placement of implants, and lots of studies have been done. In this article, the advantages and disadvantages of immediate versus delayed placement of implants have been reviewed.

Immediate transfer of synesthesia to a novel inducer.

PubMed

Mroczko, Aleksandra; Metzinger, Thomas; Singer, Wolf; Nikolić, Danko

2009-11-30

In synesthesia, a certain stimulus (e.g. grapheme) is associated automatically and consistently with a stable perceptual-like experience (e.g. color). These associations are acquired in early childhood and remain robust throughout the lifetime. Synesthetic associations can transfer to novel inducers in adulthood as one learns a second language that uses another writing system. However, it is not known how long this transfer takes. We found that grapheme-color associations can transfer to novel graphemes after only a 10-minute writing exercise. Most subjects experienced synesthetic associations immediately after learning a new Glagolitic grapheme. Using a Stroop task, we provide objective evidence for the creation of novel associations between the newly learned graphemes and synesthetic colors. Also, these associations generalized to graphemes handwritten by another person. The fast learning process and the generalization suggest that synesthesia begins at the semantic level of representation with the activation of a certain concept (the inducer), which then, uniquely for the synesthetes, activates representations at the perceptual level (the concurrent). Thus, the results imply that synesthesia is a much more flexible and plastic phenomenon than has been believed until now.

Purpose To determine the feasibility and safety of bilateral simultaneous vitreoretinal surgery in pediatric patients. Design International, multicenter, interventional, retrospective case series. Participants Patients 17 years of age or younger from 24 centers worldwide who underwent immediate sequential bilateral vitreoretinal surgery (ISBVS)—defined as vitrectomy, scleral buckle, or lensectomy using the vitreous cutter—performed in both eyes sequentially during the same anesthesia session. Methods Clinical history, surgical details and indications, time under anesthesia, and intraoperative and postoperative ophthalmic and systemic adverse events were reviewed. Main Outcome Measures Ocular and systemic adverse events. Results A total of 344 surgeries from 172 ISBVS procedures in 167 patients were included in the study. The mean age of the cohort was 1.3±2.6 years. Nonexclusive indications for ISBVS were rapidly progressive disease (74.6%), systemic morbidity placing the child at high anesthesia risk (76.0%), and residence remote from surgery location (30.2%). The most common diagnoses were retinopathy of prematurity (ROP; 72.7% [P < 0.01]; stage 3, 4.8%; stage 4A, 44.4%; stage 4B, 22.4%; stage 5, 26.4%), familial exudative vitreoretinopathy (7.0%), abusive head trauma (4.1%), persistent fetal vasculature (3.5%), congenital cataract (1.7%), posterior capsular opacification (1.7%), rhegmatogenous retinal detachment (1.7%), congenital X-linked retinoschisis (1.2%), Norrie disease (2.3%), and viral retinitis (1.2%). Mean surgical time was 143±59 minutes for both eyes. Higher ROP stage correlated with longer surgical time (P=0.02). There were no reported intraoperative ocular complications. During the immediate postoperative period, 2 eyes from different patients demonstrated unilateral vitreous haemorrhage (0.6%). No cases of endophthalmitis, choroidal hemorrhage, or hypotony occurred. Mean total anesthesia time was 203±87 minutes. There were no cases of

Some conceptual resources are sketched, namely continuing bonds, place attachment, ancestral places, home, reminder theory, and loss of place. The authors use these concepts to analyze interview material with seven Swedes and five Britons who often thought warmly of the deceased as residing in a particular place and often performing characteristic actions. The destruction of such a place, by contrast, could create a troubling, haunting absence, complicating the deceased's absent-presence.

Soft-Tissue Grafting Techniques Associated With Immediate Implant Placement.

PubMed

Bishara, Mark; Kurtzman, Gregori M; Khan, Waji; Choukroun, Joseph; Miron, Richard J

2018-02-01

Immediate implant placement often presents challenges in terms of predictably obtaining soft-tissue coverage over the implant site. While delayed implant placement offers the ability for soft tissues to grow and invade the extraction socket making their attachment around implants more predictable, immediate implant placement poses a significant risk of bacterial invasion towards the implant surface as a result of insignificant soft-tissue volume. Soft-tissue grafting techniques have often been proposed for use during immediate implant placement to augment soft-tissue deficiencies, including the use of either palatal connective tissue grafts (CTGs) or collagen-derived scaffolds. However, both of these approaches have significant drawbacks in that CTGs are harvested with high patient morbidity and collagen scaffolds remain avascular and acelluar posing a risk of infection/implant contamination. More recently, platelet-rich fibrin (PRF) has been proposed as an economical and biological means to speed soft-tissue wound healing. In combination with immediate implant placement, PRF offers an easily procurable low-cost regenerative modality that offers an efficient way to improve soft-tissue attachment around implants. Furthermore, the supra-physiological concentration of defense-fighting leukocytes in PRF, combined with a dense fibrin meshwork, is known to prevent early bacterial contamination of implant surfaces, and the biological concentrations of autologous growth factors in PRF is known to increase tissue regeneration. This article discusses soft-tissue grafting techniques associated with immediate implant placement, presents several cases demonstrating the use of PRF in routine immediate implant placement, and further discusses the biological and economic advantages of PRF for the management of soft-tissue grafting during immediate implant placement.

Effects of immediate modified feeding on infantile gastroenteritis.

PubMed Central

Hoghton, M A; Mittal, N K; Sandhu, B K; Mahdi, G

1996-01-01

BACKGROUND: Standard treatment of infants who are dehydrated as a result of acute gastroenteritis is to administer oral rehydration therapy (ORT). Traditionally, food has been withdrawn for 24-48 h, but there is no conclusive evidence that this is of any real benefit to the patient. Immediate modified feeding, in which an infant on ORT is not starved but administered a limited diet, may have benefits in the treatment of gastroenteritis, especially in children who are nutritionally compromised before they develop the illness. AIM: A pilot study was carried out to investigate the effects of giving infants suffering from acute gastroenteritis a limited modified diet in conjunction with ORT. METHOD: Infants recruited into the study by their general practitioner or by a research doctor in the hospital casualty unit of Bristol Children's Hospital were randomly allocated to receive ORT with or without immediate modified feeding. The duration of diarrhoea, weight change, and incidence of vomiting and lactose intolerance were measured in both treatment groups, and the results were compared. RESULTS: Of the infants studied, 27 received ORT and immediate modified feeding, and 32 ORT alone. The duration of diarrhoea, and incidence of vomiting or lactose intolerance were no greater in the group receiving immediate modified feeding. Patients who received ORT and immediate modified feeding appeared to gain more weight than the infants who were starved for 24-48 h, but this difference was not statistically significant. CONCLUSION: Immediate modified feeding is safe and effective, and may have nutritional advantages over traditional ORT with starvation. A similar but multicentre study using unmodified diet, i.e. child's normal diet, is being carried out by a working group of The European Society of Paediatrics, Gastroenterology and Nutrition (ESPGAN).

Place knowing of persons and populations: restoring the place work of nursing.

PubMed

Thomas, Elizabeth A

2013-12-01

Place emerges when space acquires definition in social constructions of meaning as landscape-languages, which reflect assumptions about physical and social realities. The place work of nursing, which resonated throughout Nightingale's work and the profession's evolution, focuses on human health and healing in the historical transitions and landscape-languages of populations. However, evidence-based practice dominated by empirical knowing inadequately addresses complex health and illness dynamics between place and populations. Translating evidence to the life course experiences of individuals and populations requires place knowing of human situated embodiment within discrete space. An exploration of the concept of place, its application to nursing, and the need for a place paradigm for practice is presented. A sense of salience and situated cognition has been identified as the essential element of the transformation needed in the education of nurses. Place knowing integrates other patterns of knowing (empirical, ethical, aesthetical, personal, unknowing, sociopolitical, and emancipatory) in a situated cognition. Place knowing, like other established patterns of knowing, is a significant epistemological foundation of nursing. Place knowing allows the nuanced intricately complex dynamics of embodied situated human health and illness to be examined, the salience of the particulars to be considered, and the whole of the landscape-languages to emerge.

Implant Mandibular Overdentures Retained by Immediately Loaded Implants: A 1-Year Randomized Trial Comparing the Clinical and Radiographic Outcomes Between Mini Dental Implants and Standard-Sized Implants.

PubMed

Zygogiannis, Kostas; Aartman, Irene Ha; Parsa, Azin; Tahmaseb, Ali; Wismeijer, Daniel

The aim of this 1-year randomized trial was to evaluate and compare the clinical and radiographic performance of four immediately loaded mini dental implants (MDIs) and two immediately loaded standard-sized tissue-level (STL) implants, placed in the interforaminal region of the mandible and used to retain mandibular overdentures (IODs) in completely edentulous patients. A total of 50 completely edentulous patients wearing conventional maxillary dentures and complaining about insufficient retention of their mandibular dentures were divided into two groups; 25 patients received four MDIs and 25 patients received two STL implants. The marginal bone loss (MBL) at the mesial and distal sides of each implant was assessed by means of standardized intraoral radiographs after a period of 1 year. Implant success and survival rates were also calculated. Immediate loading was possible for all patients in the first group. In the second group, an immediate loading protocol could not be applied for 10 patients. These patients were treated with a delayed loading protocol. A mean MBL of 0.42 ± 0.56 mm for the MDIs and 0.54 ± 0.49 mm for the immediately loaded STL implants was recorded at the end of the evaluation period. There was no statistically significant difference between the MDIs and the immediately loaded STL implants. Two MDIs failed, resulting in a survival rate of 98%. The success rate was 91%. For the immediately loaded conventional implants, the survival rate was 100% and the success rate 96.7% after 1 year of function. However, in 10 patients, the immediate loading protocol could not be followed. Considering the limitations of this short-term clinical study, immediate loading of four unsplinted MDIs or two splinted STL implants to retain mandibular overdentures seems to be a feasible treatment option. The marginal bone level changes around the MDIs were well within the clinically acceptable range.

Risk-taking propensity and sensitivity to punishment in adolescents with attention deficit and hyperactivity disorder symptoms and/or reading disability.

PubMed

Poon, Kean; Ho, Connie Suk-Han

2016-01-01

Many studies reported that adolescents with ADHD/RD more frequently engage in risk-taking behaviors. Very few have examined their risk taking patterns and the impact of their comorbidity. The present study compared the risk-taking propensity, sensitivity to punishment and delinquency outcome in Chinese adolescents with ADHD symptoms (AS) and/or RD using a simulated risk task, the Balloon Analogous Risk Task (BART). Adolescents with AS (n=37), RD (n=35), AS+RD (n=35), and control (n=36) were recruited from local secondary schools. Results showed that adolescents with ADHD, despite their great risk-taking propensity, were sensitive to immediate punishment whereas adolescents with RD were found to display normal risk-taking propensity, yet showed a tendency of being less sensitive to punishment. The comorbidity ADHD+RD group had the highest delinquency score, and exhibited greatest risk taking and least sensitivity to punishment, which provided further support that comorbid condition might have stronger impact on risk taking or even delinquency than the pure groups. The present findings provides a useful picture of the risk taking pattern associated with different groups, allowing for effective matching for future prevention and intervention program.

Hippocampus NMDA receptors selectively mediate latent extinction of place learning.

PubMed

Goodman, Jarid; Gabriele, Amanda; Packard, Mark G

2016-09-01

Extinction of maze learning may be achieved with or without the animal performing the previously acquired response. In typical "response extinction," animals are given the opportunity to make the previously acquired approach response toward the goal location of the maze without reinforcement. In "latent extinction," animals are not given the opportunity to make the previously acquired response and instead are confined to the previous goal location without reinforcement. Previous evidence indicates that the effectiveness of these protocols may depend on the type of memory being extinguished. Thus, one aim of the present study was to further examine the effectiveness of response and latent extinction protocols across dorsolateral striatum (DLS)-dependent response learning and hippocampus-dependent place learning tasks. In addition, previous neural inactivation experiments indicate a selective role for the hippocampus in latent extinction, but have not investigated the precise neurotransmitter mechanisms involved. Thus, the present study also examined whether latent extinction of place learning might depend on NMDA receptor activity in the hippocampus. In experiment 1, adult male Long-Evans rats were trained in a response learning task in a water plus-maze, in which animals were reinforced to make a consistent body-turn response to reach an invisible escape platform. Results indicated that response extinction, but not latent extinction, was effective at extinguishing memory in the response learning task. In experiment 2, rats were trained in a place learning task, in which animals were reinforced to approach a consistent spatial location containing the hidden escape platform. In experiment 2, animals also received intra-hippocampal infusions of the NMDA receptor antagonist 2-amino-5-phosphopentanoic acid (AP5; 5.0 or 7.5 ug/0.5 µg) or saline vehicle immediately before response or latent extinction training. Results indicated that both extinction protocols were

Gender specific effect of psychological stress and cortisol reactivity on adolescent risk taking.

Daughters, Stacey B; Gorka, Stephanie M; Matusiewicz, Alexis; Anderson, Katelyn

2013-07-01

The purpose of this study was to evaluate how psychological stress, gender and cortisol response to stress relate to risk behavior among 132 14-18 year old adolescents. Participants completed a laboratory based risk task prior to and immediately after a computerized psychological stress task, and salivary cortisol was collected from pre-stress to 60 min following initial stress exposure. Results indicate that adolescent boys (n = 59) and girls (n = 73) demonstrate different patterns of risk taking (RT) in response to stress, such that boys evidenced an increase in RT following stress exposure, whereas girls evidenced a decrease in RT. In addition, a gender by cortisol interaction demonstrated that for boys, both a smaller total cortisol output (AUCg) and peak cortisol response to stress (PC) was associated with greater stress-induced RT. Both cortisol measures were unrelated to stress-induced RT among girls. Taken together, data suggest that among boys, a blunted cortisol response to stress underlies an increase in risk taking in the context of psychological stress. Further research with an additional behavioral stress task is needed prior to drawing conclusions regarding the relation between female gender, cortisol response to stress, and risk taking in the context of psychological stress.

Research has identified impairments in Theory of Mind (ToM) abilities in depressed patients, particularly in relation to tasks involving empathetic responses and belief reasoning. We aimed to build on this research by exploring the relationship between depressed mood and cognitive ToM, specifically visual perspective-taking ability. High and low depressed participants were eye-tracked as they completed a perspective-taking task, in which they followed the instructions of a 'director' to move target objects (e.g. a "teapot with spots on") around a grid, in the presence of a temporarily-ambiguous competitor object (e.g. a "teapot with stars on"). Importantly, some of the objects in the grid were occluded from the director's (but not the participant's) view. Results revealed no group-based difference in participants' ability to use perspective cues to identify the target object. All participants were faster to select the target object when the competitor was only available to the participant, compared to when the competitor was mutually available to the participant and director. Eye-tracking measures supported this pattern, revealing that perspective directed participants' visual search immediately upon hearing the ambiguous object's name (e.g. "teapot"). We discuss how these results fit with previous studies that have shown a negative relationship between depression and ToM.

Non-Equlibrium Driven Dynamics of Continuous Attractors in Place Cell Networks

NASA Astrophysics Data System (ADS)

Zhong, Weishun; Kim, Hyun Jin; Schwab, David; Murugan, Arvind

Attractors have found much use in neuroscience as a means of information processing and decision making. Examples include associative memory with point and continuous attractors, spatial navigation and planning using place cell networks, dynamic pattern recognition among others. The functional use of such attractors requires the action of spatially and temporally varying external driving signals and yet, most theoretical work on attractors has been in the limit of small or no drive. We take steps towards understanding the non-equilibrium driven dynamics of continuous attractors in place cell networks. We establish an `equivalence principle' that relates fluctuations under a time-dependent external force to equilibrium fluctuations in a `co-moving' frame with only static forces, much like in Newtonian physics. Consequently, we analytically derive a network's capacity to encode multiple attractors as a function of the driving signal size and rate of change.

Phillips, Elery L.; Phillips, Elaine A.; Wolf, Montrose M.; Fixsen, Dean L.

1973-01-01

A series of experiments was carried out to compare several administrative systems at Achievement Place, a family style behavior modification program for pre-delinquent boys. One aspect of the motivation system at Achievement Place was the token economy in which the youths could earn or lose points that could be exchanged for privileges. Several arrangements for assigning routine tasks and for providing token consequences for task performance were compared for their effectiveness in accomplishing the tasks and for their preference by the boys. The independent variables studied included: (1) individually assigned tasks versus group assigned tasks; (2) consequences for individual performance versus consequences for group performance; (3) a peer managership that could be earned by the highest bidder versus a peer managership that could be determined democratically by the peers. The results suggested that among those systems studied the system that best met the criteria of effectiveness and preference involved a democratically elected peer manager who had the authority both to give and to take away points for his peers' performances.

NeuroPlace: Categorizing urban places according to mental states

PubMed Central

2017-01-01

Urban spaces have a great impact on how people’s emotion and behaviour. There are number of factors that impact our brain responses to a space. This paper presents a novel urban place recommendation approach, that is based on modelling in-situ EEG data. The research investigations leverages on newly affordable Electroencephalogram (EEG) headsets, which has the capability to sense mental states such as meditation and attention levels. These emerging devices have been utilized in understanding how human brains are affected by the surrounding built environments and natural spaces. In this paper, mobile EEG headsets have been used to detect mental states at different types of urban places. By analysing and modelling brain activity data, we were able to classify three different places according to the mental state signature of the users, and create an association map to guide and recommend people to therapeutic places that lessen brain fatigue and increase mental rejuvenation. Our mental states classifier has achieved accuracy of (%90.8). NeuroPlace breaks new ground not only as a mobile ubiquitous brain monitoring system for urban computing, but also as a system that can advise urban planners on the impact of specific urban planning policies and structures. We present and discuss the challenges in making our initial prototype more practical, robust, and reliable as part of our on-going research. In addition, we present some enabling applications using the proposed architecture. PMID:28898244

Take-Home Experiments in Undergraduate Fluid Mechanics Education

NASA Astrophysics Data System (ADS)

Cimbala, John

2007-11-01

Hands-on take-home experiments, assigned as homework, are useful as supplements to traditional in-class demonstrations and laboratories. Students borrow the equipment from the department's equipment room, and perform the experiment either at home or in the student lounge or student shop work area. Advantages include: (1) easy implementation, especially for large classes, (2) low cost and easy duplication of multiple units, (3) no loss of lecture time since the take-home experiment is self-contained with all necessary instructions, and (4) negligible increase in student or teaching assistant work load since the experiment is assigned as a homework problem in place of a traditional pen and paper problem. As an example, a pump flow take-home experiment was developed, implemented, and assessed in our introductory junior-level fluid mechanics course at Penn State. The experimental apparatus consists of a bucket, tape measure, submersible aquarium pump, tubing, measuring cup, and extension cord. We put together twenty sets at a total cost of less than 20 dollars per set. Students connect the tube to the pump outlet, submerge the pump in water, and measure the volume flow rate produced at various outflow elevations. They record and plot volume flow rate as a function of outlet elevation, and compare with predictions based on the manufacturer's pump performance curve (head versus volume flow rate) and flow losses. The homework assignment includes an online pre-test and post-test to assess the change in students' understanding of the principles of pump performance. The results of the assessment support a significant learning gain following the completion of the take-home experiment.

The effect of immediate dentin sealing and optical powder removal method on the fracture resistance of CAD/CAM-fabricated endocrowns.

To evaluate the effect of immediate dentin sealing and optical powder removal method on the fracture resistance of CAD/CAM-fabricated ceramic endocrowns. Seventy-eight extracted premolars were endodontically treated. Standardized endocrown preparations were done in 60 teeth. Teeth were divided equally (n = 10) depending on the treatment of dentin (delayed sealing [DS] or immediate sealing [IS]), and the methods of optical powder removal (air-water spray washing [AW]; microabrasion [MA]; or aqueous suspension of pumice [PB], followed by air-water spray washing). After cementation, specimens were thermocycled (5,000 cycles, 5°C/50°C) and stored in distilled water for 1 week. Specimens were loaded in compression using a universal testing machine until failure. Failure load was recorded, and modes of failure were examined under a stereomicroscope. Micromorphological evaluation of different dentin treatments was done under SEM (n = 3). Results were analyzed using two-way ANOVA and Bonferroni post hoc multiple comparison tests (α = 0.05). Fracture resistance of all IS groups was significantly lower than DS groups, except for AW. There was no statistically significant difference between powder removal methods. Immediate dentin sealing does not improve the fracture resistance of endocrown restorations. Air-water spray washing is adequate to remove the optical powder after optical scanning impression taking.

To assess the cost-effectiveness of using human papillomavirus testing (HPV triage) in the management of women with minor cytological abnormalities in Sweden. An economic analysis based on a clinical trial, complemented with data from published meta-analyses on accuracy of HPV triage. The study takes perspective of the Swedish healthcare system. The Swedish population-based cervical cancer screening program. A decision analytic model was constructed to evaluate cost-effectiveness of HPV triage compared to repeat cytology and immediate colposcopy with biopsy, stratifying by index cytology (ASCUS = atypical squamous cells of undetermined significance, and LSIL = low-grade squamous intraepithelial lesion) and age (23-60 years, <30 years and ≥30 years). Costs, incremental cost, incremental effectiveness and incremental cost per additional high-grade lesion (CIN2+) detected. For women with ASCUS ≥30 years, HPV triage is the least costly alternative, whereas immediate colposcopy with biopsy provides the most effective option at an incremental cost-effectiveness ratio (ICER) of SEK 2,056 per additional case of CIN2+ detected. For LSIL (all age groups) and ASCUS (23-60 years and <30 years), HPV triage is dominated by immediate colposcopy and biopsy. Model results were sensitive to HPV test cost changes. With improved HPV testing techniques at lower costs, HPV triage can become a cost-effective alternative for follow-up of minor cytological abnormalities. Today, immediate colposcopy with biopsy is a cost-effective alternative compared to HPV triage and repeat cytology.

Cue reactivity (CR) research has reliably demonstrated robust cue-induced responding among smokers exposed to common proximal smoking cues (e.g., cigarettes, lighter). More recent work demonstrates that distal stimuli, most notably the actual environments in which smoking previously occurred, can also gain associative control over craving. In the real world proximal cues always occur within an environment; thus, a more informative test of how cues affect smokers might be to present these two cue types simultaneously. Using a combined-cue counterbalanced cue reactivity paradigm, the present study tested the impact of proximal (smoking and neutral) + personal environment (smoking and nonsmoking places) pictorial cues, on smokers' subjective and behavioral cue reactivity; as well as the extent to which cue-induced craving predicts immediate subsequent smoking in a within-subjects design. As anticipated, the dual smoking cue combination (ProxS+EnvS) led to the greatest cue-induced craving relative to the other three cue combinations (ProxS+EnvN, ProxN+EnvS, ProxN+-EnvN), p's < .004. Dual smoking cues also led to significantly shorter post-trial latencies to smoke, p's < .01. Overall cue reactivity difference score (post-trial craving minus baseline craving) was predictive of subsequent immediate smoking indexed by: Post-trial latency to smoke (B= -2.69, SE= 9.02; t(143) = -2.98, p = .003); total puff volume (B= 2.99, SE= 1.13; t(143)= 2.65, p = .009); and total number of puffs (B= .053, SE= .027; t(143)= 1.95, p = .05). The implications of these findings for better understanding the impact of cues on smoking behavior and cessation are discussed. This novel cue reactivity study examined smokers' reactivity to combined proximal and distal smoking cues. Exposure to a combination of two smoking cues (proximal and environment) led to the greatest increases in cue-induced craving and smoking behavior compared to all other cue combinations. Further, the overall magnitude of

The Vote and Vax program: public health at polling places.

Although influenza-associated illness is a major cause of hospitalizations and death among older Americans, only half of adults aged 50 or older-for whom influenza vaccinations are recommended-receive an annual influenza vaccination. National elections, which draw a large number of older voters, take place during influenza vaccination season and represent an untapped opportunity for large-scale delivery of vaccinations. In 2006, the Robert Wood Johnson Foundation launched a program to evaluate the feasibility of delivering influenza vaccinations near polling places. Twenty-five public health agencies were each provided grants of $8000 and asked to implement at least two Vote and Vax clinics. Immunizers were required to obtain prior permission from local election authorities and to charge fees as they would at their other community-based clinics. Influenza vaccination had to be made available both to voters and to nonvoters. On election day, the initiative delivered 13790 influenza vaccinations at 127 polling places in 14 states. More than 80 percent of adult vaccine recipients were in the Centers for Disease Prevention and Control-defined priority groups and 28 percent were "new" influenza vaccination recipients. Vote and Vax is a potentially national strategy that could significantly expand the delivery of influenza vaccinations.

As climate change impacts are felt around the globe, people are increasingly exposed to changes in weather patterns, wildlife and vegetation, and water and food quality, access and availability in their local regions. These changes can impact human health and well-being in a variety of ways: increased risk of foodborne and waterborne diseases; increased frequency and distribution of vector-borne disease; increased mortality and injury due to extreme weather events and heat waves; increased respiratory and cardiovascular disease due to changes in air quality and increased allergens in the air; and increased susceptibility to mental and emotional health challenges. While climate change is a global phenomenon, the impacts are experienced most acutely in place; as such, a sense of place, place-attachment, and place-based identities are important indicators for climate-related health and adaptation. Representing one of the first qualitative case studies to examine the connections among climate change, a changing sense of place, and health in an Inuit context, this research draws data from a multi-year community-driven case study situated in the Inuit community of Rigolet, Nunatsiavut, Canada. Data informing this paper were drawn from the narrative analysis of 72 in-depth interviews conducted from November 2009 to October 2010, as well as from the descriptive analysis of 112 questionnaires from a survey in October 2010 (95% response rate). The findings illustrated that climate change is negatively affecting feelings of place attachment by disrupting hunting, fishing, foraging, trapping, and traveling, and changing local landscapes-changes which subsequently impact physical, mental, and emotional health and well-being. These results also highlight the need to develop context-specific climate-health planning and adaptation programs, and call for an understanding of place-attachment as a vital indicator of health and well-being and for climate change to be framed as an

2014-01-01

Objective To determine if immediate (within 6 hours of adequate resuscitation) single-stage repair of complex craniofacial injuries could be accomplished with acceptable morbidity and mortality taking into consideration the cosmetic appearance of the patient. Patients and Methods A total of 26 patients (19 men, 7 women) ranging in age from 8 to 58 years with Glasgow Coma Scale scores of 5 to 15 all had a combined single-stage repair of their complex craniofacial injuries within 6 hours of their admission. After initial assessment and adequate resuscitation, they were evaluated with three-dimensional computed tomography of the face and head. Coronal skin flap was used for maximum exposure for frontal sinus exenteration as well as dural repair, cortical debridement, calvarial reconstruction, and titanium mesh placement. Results Neurosurgical outcome at both the early and late evaluations was judged as good in 22 of 26 patients (85%), moderate in 3 of 26 (11%), and poor in 1 of the 26 (3.8%). Cosmetic surgical outcome at the early evaluation showed 17 of 26 (65%) to be excellent, 4 of 26 (15.5%) to be good, 4 patients (15.5%) to be fair, and 1 patient (3.8%) to be poor. At the late reevaluation, the fair had improved to good with an additional reconstructive procedure, and the poor had improved to fair with another surgery. There was no calvarial osteomyelitis, graft resorption, or intracranial abscess. Complications included three patients (11%): one (3.8%) had tension pneumocephaly and meningitis, one (3.8%) had delayed cerebrospinal fluid leak with recurrent attacks of meningitis, and one had a maxillary sinus infection (3.8%) secondary to front maxillary fistula. Conclusion The immediate single-stage repair of complex craniofacial injuries can be performed with acceptable results, a decreased need for reoperation, and improved cosmetic and functional outcomes.

This 1-year cohort study investigated stability and peri-implant marginal bone level of immediately loaded mini dental implants used to retain overdentures. Each of 30 edentulous patients received 4 mini dental implants (1.8 mm × 13 mm) in the interforaminal mandibular region. The implants were immediately loaded with pre-made overdentures. Outcome measures included implant stability and bone resorption. Implant stability was measured using the Periotest Classic(®) device immediately after placement and on the 3rd and 6th weeks and the 4th, 6th and 12th months postoperatively. The peri-implant marginal bone level (PIBL) was evaluated at the implant's mesial and distal sides from the polished platform to the marginal crest. Radiographs were taken using a tailored film holder to reproducibly position the X-ray tube at the 6th week, 4th and 12th months postoperatively. The primary stability (Periotest value, PTV) measured -0.27 ± 3.41 on a scale of -8 to + 50 (lower PTV reflects higher stability). The secondary stability decreased significantly until week 6 (mean PTV = 7.61 ± 7.05) then increased significantly reaching (PTV = 6.17 ± 6.15) at 12 months. The mean PIBL measured -0.40 mm after 1 year of functional loading, with no statistically significant differences at the various follow-ups (p = 0.218). Mini dental implants placed into the interforaminal region could achieve a favorable primary stability for immediate loading. The follow-up Periotest values fluctuated, apparently reflecting the dynamics of bone remodeling, with the implants remaining clinically stable (98.3%) after 1 year of function. The 1-year bone resorption around immediately loaded MDIs is within the clinically acceptable range for standard implants. Copyright © 2014 Elsevier GmbH. All rights reserved.

Identity as "knowing your place": the narrative construction of space in a healthcare profession.

2015-03-01

The construction of space in which a story takes place can have important consequences for the evaluation of health interventions. In this article, we explore the ways professionals narratively position themselves in a situation, treating identity literally as "knowing one's place." More specifically, we explore the spatial language health professionals use to describe their work. Using descriptions of professionals in a drug habilitation organization, we illustrate how they use route (i.e., an active tour through the space), survey (i.e., a stationary viewpoint from above), and gaze perspectives (i.e. a stable viewpoint onto a place) to explain the work situations they encounter. Each of these perspectives facilitates a different mode of evaluation in terms of distance, emotion, and identity. We propose opportunities for research and implications of the ways in which spaces and spatial perspectives set the scene in the narratives of healthcare professionals. © The Author(s) 2015.

Immediate effects of nectar robbing by Palestine sunbirds (Nectarinia osea) on nectar alkaloid concentrations in tree tobacco (Nicotiana glauca).

PubMed

Kaczorowski, Rainee L; Koplovich, Avi; Sporer, Frank; Wink, Michael; Markman, Shai

2014-04-01

Plant secondary metabolites (PSMs), such as alkaloids, are often found in many parts of a plant, including flowers, providing protection to the plant from various types of herbivores or microbes. PSMs are also present in the floral nectar of many species, but typically at lower concentrations than in other parts of the plant. Nectar robbers often damage floral tissue to access the nectar. By doing so, these nectar robbers may initiate an increase of PSMs in the floral nectar. It is often assumed that it takes at least a few hours before the plant demonstrates an increase in PSMs. Here, we addressed the question of whether PSMs in the floral tissue are immediately being released into the floral nectar following nectar robbing. To address this research question, we investigated whether there was an immediate effect of nectar robbing by the Palestine Sunbird (Nectarinia osea) on the concentration of nectar alkaloids, nicotine and anabasine, in Tree Tobacco (Nicotiana glauca). We found that the concentration of anabasine, but not nicotine, significantly increased in floral nectar immediately following simulated nectar robbing. These findings suggest that nectar robbers could be ingesting greater amounts of PSMs than they would if they visit flowers legitimately. As a consequence, increased consumption of neurotoxic nectar alkaloids or other PSMs could have negative effects on the nectar robber.

Does life history predict risk-taking behavior of wintering dabbling ducks?

USGS Publications Warehouse

Ackerman, Joshua T.; Eadie, J.M.; Moore, T.G.

2006-01-01

Life-history theory predicts that longer-lived, less fecund species should take fewer risks when exposed to predation than shorter-lived, more fecund species. We tested this prediction for seven species of dabbling ducks (Anas) by measuring the approach behavior (behavior of ducks when approaching potential landing sites) of 1099 duck flocks during 37 hunting trials and 491 flocks during 13 trials conducted immediately after the 1999-2000 waterfowl hunting season in California, USA. We also experimentally manipulated the attractiveness of the study site by using two decoy treatments: (1) traditional, stationary decoys only, and (2) traditional decoys in conjunction with a mechanical spinning-wing decoy. Approach behavior of ducks was strongly correlated with their life history. Minimum approach distance was negatively correlated with reproductive output during each decoy treatment and trial type. Similarly, the proportion of flocks taking risk (approaching landing sites to within 45 m) was positively correlated with reproductive output. We found similar patterns of approach behavior in relation to other life-history parameters (i.e., adult female body mass and annual adult female survival rate). Thus, species characterized by a slower life-history strategy (e.g., Northern Pintail [A. acuta]) were more risk-averse than species with a faster life-history strategy (e.g., Cinnamon Teal [A. cyanoptera]). Furthermore, although we were able to reduce risk-averseness using the spinning-wing decoy, we were unable to override the influence of life history on risk-taking behavior. Alternative explanations did not account for the observed correlation between approach behavior and life-history parameters. These results suggest that life history influences the risk-taking behavior of dabbling ducks and provide an explanation for the differential vulnerability of waterfowl to harvest. ??

Immediate and delayed cutaneous reactions to radiocontrast media.

PubMed

Brockow, Knut

2012-01-01

Hypersensitivity reactions to contrast media (CM) are frequent causes of anaphylaxis and drug exanthemas. Adverse events after CM exposure are classified into immediate (≤1 h) and non-immediate reactions (>1 h), with differing mechanisms. In the majority of patients with immediate reactions, IgE-mediated allergy cannot be demonstrated, and the underlying mechanism remains unknown. However, recent data have provided evidence for skin test positivity and/or specific IgE in some patients. T cell-mediated hypersensitivity is the responsible mechanism for the majority of non-immediate skin eruptions. These insights have consequences for diagnosis and prevention. Skin testing evolves to be a useful tool for diagnosis of CM allergy. Skin tests have been employed to confirm this hypersensitivity. Previous reactors have an increased risk to develop new reactions upon repeated exposure; however, other risk factors are poorly defined. The use of skin tests for the selection of a 'safe' CM is under investigation with promising results. In vitro tests to search for CM-specific cell activation include flow cytometric approaches, lymphocyte cultures and construction of cell lines and hybridomas. Premedication of previous reactors is common practice among radiologists; however, breakthrough reactions are a concern, and physicians should not rely on the efficacy of pharmacological premedication.

Mastectomy is an essential but disfiguring operation in cancer treatment. The negative impact on body image can however be prevented by immediate reconstruction. The aim of this study was to determine the reasons why patients choose to have or not to have immediate breast reconstruction. This is a cross sectional descriptive study of breast cancer patients post-mastectomy who had and had not undergone immediate breast reconstruction. The patients were asked a series of questions to ascertain the reasons why they chose or did not choose immediate breast reconstruction. 136 patients in total were interviewed of which 23 had undergone immediate breast reconstruction. 36.8% of the patients had been offered reconstruction. In the non-reconstructed group, the main reason for not having reconstruction were fear of additional surgery. In the group that had reconstruction done, the main reason was to feel whole again. Low on the list were reasons such as trying to improve marital or sexual relations. Only a third of patients undergoing mastectomy were offered immediate reconstruction. In public hospitals in developing countries, limited operating time and availability of plastic surgery services are major barriers to more women being offered the option.

Sy, Jolene R.; Vollmer, Timothy R.

2012-01-01

We evaluated the discrimination acquisition of individuals with developmental disabilities under immediate and delayed reinforcement. In Experiment 1, discrimination between two alternatives was examined when reinforcement was immediate or delayed by 20 s, 30 s, or 40 s. In Experiment 2, discrimination between 2 alternatives was compared across an immediate reinforcement condition and a delayed reinforcement condition in which subjects could respond during the delay. In Experiment 3, discrimination among 4 alternatives was compared across immediate and delayed reinforcement. In Experiment 4, discrimination between 2 alternatives was examined when reinforcement was immediate and 0-s or 30-s intertrial intervals (ITI) were programmed. For most subjects, discrimination acquisition occurred under immediate reinforcement. However, for some subjects, introducing delays slowed or prevented discrimination acquisition under some conditions. Results from Experiment 4 suggest that longer ITIs cannot account for the lack of discrimination under delayed reinforcement. PMID:23322925

Expressing freedom and taking liberties: the paradoxes of aberrant science.

PubMed

Little, M

2006-06-01

Complete freedom does not exist, despite people's preparedness to die for it. Scientific freedom is much defended and yet much misunderstood. Scientists have limits imposed on their freedom by the disciplines and discourse communities in which they place themselves. Freedom within these socially constructed constraints needs to be distinguished from taking liberties with the rules and practices that make up these constraints, and validate the activities of special groups within society. Scientists (and the public) perceive taking liberties with science's rules and practices as aberrant science, and they often react punitively. Aberrant science can be broadly examined under four headings: wicked science, naughty science, dysfunctional science, and ideologically unacceptable science. When we examine examples of perceived aberrant science, we find that these categories of "misconduct" are connected and often confused. Scientific freedom needs to be redefined with due regard to current understandings of scientists as human beings facing powerful social pressures to deliver results of a particular kind.

Oxygen Saturation is one of the important data to determine patient status and worldwide applied in several situations. Evaluation about status of immediate perinatal period of the infant usually uses clinical assessment, Apgar scoring, which had been used for a long time without other scientific measurement. Pulse oximeter the non-invasive measurement of oxygen saturation, may play role for oxygen saturation evaluation in newborn that immediately change from intra to extra uterine environment. Monitoring the time duration that immediately born infants by normal labor or Cesarean section modes, used to archived target oxygen saturation (SpO) and looking for the other factors that influence oxygen saturation adaptation. The data of the 553 infants born in Charoenkrung Pracharak Hospital, Bangkok, Thailand between October 2012 and April 2013 were collected. The 204 healthy newborns that met all criteria were studied. All infants were recorded pulse oximeter from the second to the tenth minute after birth. They were grouped by several factors such as maternal gravidity, gestational age, mode of delivery, Apgar score, birth weight, and sex. Time interval to achieve target oxygen saturation (SpO2 ≥ 90%) was collected for analysis. The oxygen saturation of infants immediately after birth showed an increase. Median time interval was 6.5 (2-10) minutes for 90% saturation and 7 (2-10) minutes for 95% saturation, respectively. Only mode of delivery showed statistical significant time difference (p < 0.001). A Cox proportional hazards analysis of the Kaplan-Meier curves demonstrated that infants born by cesarean delivery took significantly longer time to reach a stable SpO2 ≥ 90% than infants born by vaginal delivery (95% CI = 1.28 to 2.74; p < 0.01). A newly born infant has to take 6.5 minutes (2-10) after birth to adjust their oxygen saturation to reach normal higher level of extra uterine life, median SpO2 of 90%. Furthermore, mode of delivery makes a significant

To elucidate spatial and cognitive function of the septal nuclei, neural activity was recorded from alert monkeys during performance of a place-dependent go/no-go (PGN) task. Response/reinforcement contingencies of given objects were conditional upon the location of a motorized, movable device (cab) containing a monkey in one of four places. The task was initiated by presentation of the outside view (place phase) followed by presentation of an object (object phase) selected from a total of four. A lever press was reinforced only if the correct object was seen in its corresponding place, and the same object was never reinforced in any of the other three places. Of 430 septal neurons recorded, the responses during the place phase in the four places were significantly different in 58 neurons. Responses of eight of these neurons were also place-differential during the object phase as well as the place phase. Furthermore, when the outside view was not presented before the object phase, differential responses in the object phase disappeared. Responses of 91 neurons in the object phase were differential in terms of go/no-go responses and reward availability. Of these 91 neurons, 72 were further tested on a place-independent asymmetrical go/no-go (AGN) task, which required no conditional discrimination. Forty-three neurons responded differentially only in the PGN task. It is thus concluded that this PGN-specific activity reflected conditional place-object relations. Of the remaining 29 neurons that responded differentially in both tasks, 21 were further tested by a place-independent symmetrical go/no-go task (no-go responses were also rewarded). Responses of 19 of these 21 neurons were related to the reward/nonreward contingency but not to the response contingency. The results suggest that septal nuclei are involved in integrating spatial information, conditional place-object relations, and reward/nonreward contingency.

Immediate and long-term galvanotactic responses of Amoeba proteus to dc electric fields.

2000-01-01

The long-term and immediate galvanotactic responses of Amoeba proteus to the direct current electric fields (dcEFs) were studied with the methods of computer-aided image analysis. It was found that in contrast to earlier reports, amoebae continued locomotion towards cathode (the negative pole) for hours and the increase in the field strength in the range 300-600 mV/mm caused the straightening of cell trajectories accompanied by the decreased frequency of the lateral pseudopods formation and lesser change in the speed of cell movement. In the cell regions pointing to the anode, the formation of new pseudopodia was prevented and the higher cEFs strength the more extended were the regions in which formation of new pseudopods was inhibited. Replacement of calcium with magnesium in the extracellular medium reduced the galvanotactic cell responses. Research on the localisation and kinetics of the primary cell responses to the dcEF or to change in its direction revealed that the primary cell responses occurred at the anode oriented cell regions. The cell response to the field reversal appeared to be localised and to take place in less than 1 sec. First the retraction and withdrawal of the anode-directed pseudopodium was observed whereas the uroid (cell tail) moved for 10-40 sec in the original direction before it begun to react to the field reversal. The exposure of amoebae to the dcEFs sensitised them to the reversion in the field direction and induced an acceleration of cell responses. The results presented are difficult to reconcile with the attempt to explain the cell galvanotaxis as a consequence of the membrane protein lateral electrophoresis or electroosmosis. It is suggested that the lateral electrophoresis of ions and the modification of ionic conditions at the vicinity of ion channels may be involved in the induction of fast responses of cells to external dcEFs.

Delayed stent implantation after restoration of normal epicardial flow by a minimalist immediate mechanical intervention aims to decrease the rate of distal embolization and impaired myocardial reperfusion after percutaneous coronary intervention. We sought to confirm whether a delayed stenting (DS) approach (24-48 hours) improves myocardial reperfusion, versus immediate stenting, in patients with acute ST-segment-elevation myocardial infarction undergoing primary percutaneous coronary intervention. In the prospective, randomized, open-label minimalist immediate mechanical intervention (MIMI) trial, patients (n=140) with ST-segment-elevation myocardial infarction ≤12 hours were randomized to immediate stenting (n=73) or DS (n=67) after Thrombolysis In Myocardial Infarction 3 flow restoration by thrombus aspiration. Patients in the DS group underwent a second coronary arteriography for stent implantation a median of 36 hours (interquartile range 29-46) after randomization. The primary end point was microvascular obstruction (% left ventricular mass) on cardiac magnetic resonance imaging performed 5 days (interquartile range 4-6) after the first procedure. There was a nonsignificant trend toward lower microvascular obstruction in the immediate stenting group compared with DS group (1.88% versus 3.96%; P=0.051), which became significant after adjustment for the area at risk (P=0.049). Median infarct weight, left ventricular ejection fraction, and infarct size did not differ between groups. No difference in 6-month outcomes was apparent for the rate of major cardiovascular and cerebral events. The present findings do not support a strategy of DS versus immediate stenting in patients with ST-segment-elevation infarction undergoing primary percutaneous coronary intervention and even suggested a deleterious effect of DS on microvascular obstruction size.

Ageing-in-place is considered important for the health of older adults. In this paper, inspired by a constructivist approach to ageing-in-place, we unravel professionals' and older adults' constructions of ageing-in-place. Their perspectives are studied in relation to a policy that aims to develop so-called 'lifecycle-robust neighbourhoods' in the southern part of the Netherlands. We conducted a photovoice study in which 18 older adults (70-85 years) living independently and 14 professionals (social workers, housing consultants, neighbourhood managers and community workers) were asked to photograph and discuss the places they consider important for ageing-in-place. Based on a theoretically informed analysis of the data, we found that professionals primarily consider objective characteristics of neighbourhoods such as access to amenities, mobility and meeting places as important enablers for older adults to remain living independently. Analysis of older adults' photographs and stories show that they associate ageing-in-place with specific lived experiences and attachments to specific, intangible and memory-laden public places. We conclude that exploring these experiences helps to increase current knowledge about place attachment in old age. Copyright © 2017 Elsevier Ltd. All rights reserved.

Microgravity Smoldering Combustion Takes Flight

NASA Technical Reports Server (NTRS)

1996-01-01

The Microgravity Smoldering Combustion (MSC) experiment lifted off aboard the Space Shuttle Endeavour in September 1995 on the STS-69 mission. This experiment is part of series of studies focused on the smolder characteristics of porous, combustible materials in a microgravity environment. Smoldering is a nonflaming form of combustion that takes place in the interior of combustible materials. Common examples of smoldering are nonflaming embers, charcoal briquettes, and cigarettes. The objective of the study is to provide a better understanding of the controlling mechanisms of smoldering, both in microgravity and Earth gravity. As with other forms of combustion, gravity affects the availability of air and the transport of heat, and therefore, the rate of combustion. Results of the microgravity experiments will be compared with identical experiments carried out in Earth's gravity. They also will be used to verify present theories of smoldering combustion and will provide new insights into the process of smoldering combustion, enhancing our fundamental understanding of this frequently encountered combustion process and guiding improvement in fire safety practices.

An increasing number of patients show immediate selective hypersensitivity reactions to clavulanic acid (CLV) and amoxicillin (AX), probably due to their increased prescription. The maintenance of this response should be established. To assess that the immediate hypersensitivity selective response to AX or to CLV is maintained after repeated administration of penicillin G (PG)/penicillin V (PV) and AX. Patients with proven immediate hypersensitivity to AX (Group A) or CLV (Group B) were included. Diagnosis was performed using skin tests with major and minor determinants of PG (PPL/MDM), AX and CLV and by drug provocation test (DPT) if required. Selectivity was established by confirming tolerance to PG/PV (Group A) and to PG/PV and AX (Group B). The maintenance of the selective response was verified by repeating DPT, 15 days after the initial investigation, with the same procedure. Of 51 patients, 78% belonged to Group A and 22% to Group B. Most had anaphylaxis. In Group A, 72% were skin test positive; 28% required DPT. In Group B, 63% were skin test positive; 37% required DPT. Only two AX-selective cases developed positive responses after re-provocation with PG/PV. No cases selective for CLV developed a positive response to PG, PV or AX. The selective response to AX appears consistent, and a response to penicillin determinants only develops in a minority of cases. For the case of CLV, the selective response appears not to be modified by exposure to penicillin determinants, meaning that patients with CLV allergy can take penicillin derivatives safely. © 2015 John Wiley & Sons A/S.

Tooth autotransplantation is a useful surgical method to replace a nonrestorable tooth. We reported our experiences in the replacement of mandibular nonrestorable molars by immediate autotransplantation in a Chinese population. Thirty-five mandibular third molars with open or closed apices from 34 patients were autotransplanted into the same or contralateral fresh recipient sites immediately after the extraction of the nonrestorable mandibular molars. Root canal treatment was routinely performed in the closed-apical molars within 1 month after surgery. Clinical and radiographic examination of the transplanted donor molars was done after surgery. Two teeth were been extracted for progressive root resorption. The remaining 33 autotransplanted teeth were asymptomatic and functioning after a mean follow-up period of 5.2 years. No infection, ankylosis, loss of the transplants, or root resorption was noted in the remaining autotransplanted teeth. Immediate autotransplantation of the mandibular third molar is a reasonable and alternative treatment to replace a nonrestorable tooth in China. Copyright © 2010 Mosby, Inc. All rights reserved.

Utilizing Education and Perspective Taking to Remediate the Stigma of Taking Antidepressants.

The incidence of depression has been increasing. One of the best interventions for depression is taking antidepressant medications. However, the stigma of taking antidepressants has been shown to be a barrier not only to seeking an antidepressant regimen but also adhering to it. This may have negative consequences for people who suffer from depression. Thus, in two studies, we investigate the incidence of felt stigma of taking antidepressants among clinically depressed individuals who take antidepressants and the effectiveness of two possible interventions to reduce this stigma among others. Study 1 revealed that stigma toward individuals who take antidepressants is a reality, either because people were not educated about depression and antidepressants, or because they did not show empathy or did not take on perspectives from the victim's point-of-view. Based on these results, we used an experimental design in Study 2 to investigate the effects of education and perspective-taking interventions in diminishing the stigma of taking antidepressants. These results suggest that participant gender played a moderating role in the effectiveness of education and perspective taking, such that a combination of the two interventions resulted in lower stigma for men but not for women. These results suggest that people can be trained (using a simple, low-fidelity intervention) to be more accepting of antidepressant use among their friends, family members, and colleagues, resulting in better outcomes for those who benefit from taking antidepressants.

The paper presents clinical-radiological research on the impact of the new semi-cement luting agent in the immediately loaded implant-supported restoration on alveolar ridge resorption. 25 patients with a partially edentulous alveolar ridge in the anterior section of the maxilla or mandible were included in the study. The implants were inserted with the application of traditional burs or with a Piezosurgery device supplied by Mectron. Taking into account the method of implant bed preparation, the scientific material was divided into two groups. The implants were loaded immediately with single crown restorations cemented with the Implantlink semi cement application. The following indices were taken into consideration: pocket depth around implant calculated at four measuring points, marginal alveolar bone loss measured using radio-visiography, the 3-degree Wachtel scale of healing of the soft tissue. In addition, the presence and possible width or height of any recession around the implants was measured. The success of the implant treatment was assessed according to the Albrektsson success criteria. The research results were subjected to statistical analysis. The results of our study revealed no influence of the Implant-link semi cement on the crestal bone level, regardless of the bone bed preparation technique.

Women who have undergone prior augmentation mammoplasty represent a unique subset of breast cancer patients with several options available for breast reconstruction. We performed a single institution review of surgical outcomes of breast reconstruction performed in patients with breast cancer with prior history of subpectoral breast augmentation. Institutional review board-approved retrospective review was conducted among patients with previously mentioned criteria treated at our institution between 2000 and 2014. Reconstructions were grouped into 2 categories as follows: (1) removal of preexisting subpectoral implant during mastectomy with immediate tissue expander placement and (2) implant-sparing mastectomy followed by delayed exchange to a larger implant. We reviewed demographics, tumor features, and reconstruction outcomes of these groups. Fifty-three patients had preexisting subpectoral implants. Of the 63 breast reconstructions performed, 18 (28.6%) had immediate tissue expander placed and 45 (71.4%) had implant-sparing mastectomy followed by delayed implant exchange. The groups were comparable based on age, body mass index, cancer type, tumor grade, TNM stage at presentation, and hormonal receptor status. No significant difference was noted between tumor margins or subsequent recurrence, mastectomy specimen weight, removed implant volume, volume of implant placed during reconstruction, or time from mastectomy to final implant placement. Rates of complications were significantly higher in the tissue expander group compared to the implant-sparing mastectomy group 7 (38.9%) versus 4 (8.9%) (P = 0.005). Implant-sparing mastectomy with delayed implant exchange in patients with preexisting subpectoral implants is safe and has fewer complications compared to tissue expander placement. There was no difference noted in the final volume of implant placed, time interval for final implant placement, or tumor margins.

The effects of alveolar bone socket geometry and bone-implant contact on implant biomechanics, and resulting strain distributions in bone were investigated. Following extraction of lateral incisors on a cadaver mandible, immediate implants were placed and bone-implant contact area, stability and bone strain were measured. In situ biomechanical testing coupled with micro X-ray microscope (μ-XRM) illustrated less stiff bone-implant complexes (701-822 N/mm) compared with bone-periodontal ligament (PDL)-tooth complexes (791-913 N/mm). X-ray tomograms illustrated that the cause of reduced stiffness was due to reduced and limited bone-implant contact. Heterogeneous elemental composition of bone was identified by using energy dispersive X-ray spectroscopy (EDS). The novel aspect of this study was the application of a new experimental mechanics method, that is, digital volume correlation, which allowed mapping of strains in volumes of alveolar bone in contact with a loaded implant. The identified surface and subsurface strain concentrations were a manifestation of load transferred to bone through bone-implant contact based on bone-implant geometry, quality of bone, implant placement, and implant design. 3D strain mapping indicated that strain concentrations are not exclusive to the bone-implant contact regions, but also extend into bone not directly in contact with the implant. The implications of the observed strain concentrations are discussed in the context of mechanobiology. Although a plausible explanation of surgical complications for immediate implant treatment is provided, extrapolation of results is only warranted by future systematic studies on more cadaver specimens and/or in vivo small scale animal models.

Prior work suggests that some but not all antihypertensive treatments may benefit cognition and risk for Alzheimer's disease, independent of stroke. Angiotensin II receptor blockers (ARBs) have been highlighted as one antihypertensive drug class that may confer greatest benefit. The participants comprised 1626 nondemented adults, aged 55-91 years, recruited from Alzheimer's Disease Neuroimaging Initiative sites. Three groups were compared: ARB users (HTN-ARBs), other antihypertensive drug users (HTN-Other), and normotensives. In post hoc analyses, we also examined (1) users of ARBs and angiotensin-converting enzyme inhibitors (ACEIs), (2) users of blood-brain barrier (BBB)-crossing ARBs and users of non-BBB-crossing ARBs, and (3) users of BBB-crossing ARBs and ACEIs (BBB crossers) and users of non-BBB-crossing ARBs and ACEIs (BBB noncrossers). Groups were compared regarding cognition and magnetic resonance imaging measures of brain volume and white matter hyperintensities (WMH), using analysis of covariance and multilevel models. At baseline, the HTN-Other group performed worse than normotensives on Rey Auditory Verbal Learning Test (RAVLT) Immediate Recall (p = 0.002), Delayed Recall (p < 0.001), Recognition Memory (p = 0.001), and Trails A (p < 0.001) and B (p = 0.01). ARB users performed better than the HTN-Other group on Recognition Memory (p = 0.04) and worse than normotensives on Trails A (p = 0.04). The HTN-Other group performed worse than normotensives on Logical Memory Immediate (p = 0.02) and Delayed Recall over the 3-year follow-up (p = 0.007). Over the follow-up period, those taking BBB-crossing ARBs performed better than the HTN-Other group on AVLT Delayed Recall (p = 0.04), Logical Memory Immediate (p = 0.02), and Delayed Recall (p = 0.05). They also had fewer WMH than the HTN-Other group (p = 0.008) and those taking non-BBB-crossing ARBs (p = 0.05). There were no group differences in brain

Immediate Extinction Attenuates Spontaneous Recovery and Reinstatement in a Passive Avoidance Paradigm.

PubMed

Briggs, James F; Fava, Devin A

2016-08-01

Recent research suggests that extinction occurring shortly after fear conditioning attenuates spontaneous recovery and reinstatement of fear. Two experiments investigated whether immediate extinction would prevent spontaneous recovery and reinstatement of fear using a passive avoidance paradigm. In Experiment 1, naive female adult rats (N = 40) received extinction training either immediately or 24 hours (delayed) after fear conditioning. Both extinction groups showed a significant reduction in fear at a 1-day test. At a 15-day test, spontaneous recovery was observed in the delayed extinction group while the immediate extinction group continued to show significant extinction. In Experiment 2, using a naive group of adult female rats (N = 16), the extinction result was replicated in both the immediate and delayed extinction groups at the 1-day interval. Reinstatement of fear, elicited by foot-shock in a neutral environment, was observed for the delayed group but not for the immediate group. By utilizing the passive-avoidance paradigm, these experiments replicate and extend previous findings that immediate extinction attenuates spontaneous recovery and reinstatement of fear. © The Author(s) 2016.

Immediate tool incorporation processes determine human motor planning with tools

PubMed Central

Ganesh, G.; Yoshioka, T.; Osu, R.; Ikegami, T.

2014-01-01

Human dexterity with tools is believed to stem from our ability to incorporate and use tools as parts of our body. However tool incorporation, evident as extensions in our body representation and peri-personal space, has been observed predominantly after extended tool exposures and does not explain our immediate motor behaviours when we change tools. Here we utilize two novel experiments to elucidate the presence of additional immediate tool incorporation effects that determine motor planning with tools. Interestingly, tools were observed to immediately induce a trial-by-trial, tool length dependent shortening of the perceived limb lengths, opposite to observations of elongations after extended tool use. Our results thus exhibit that tools induce a dual effect on our body representation; an immediate shortening that critically affects motor planning with a new tool, and the slow elongation, probably a consequence of skill related changes in sensory-motor mappings with the repeated use of the tool.

The aim of this study was to evaluate the stability during healing and before loading of implants placed at two different supracrestal levels according to their collar texture. This retrospective study included patients who received posterior implants with the same macro design. Implants with a machined collar were placed 0.3 mm above the crestal bone (M group), while those with a laser-microtextured collar were placed 1 mm above the crestal bone (L group). All implants healed in a single stage with healing abutments. Implant stability quotient (ISQ) values were determined using resonance frequency analysis immediately after implant placement during surgery and after 1, 4, 8, and 12 weeks after surgery. Other evaluated factors for stability included the implant diameter and length and the site of placement (maxilla or mandible). In total, 103 implants (47 L, 56 M) were evaluated. The median ISQ values at baseline and 1 week after placement were significantly higher for the M group than for the L group (p=0.006 and p=0.031, respectively). There were no differences at the subsequent observation points. The ISQ value was higher for wide-diameter than regular diameter (p=0.001) and mandibular implants than maxillary implants (p=0.001 at 0-8. weeks; p=0.012 at 12 weeks) at all observation points. When diameter data were neglected, the implant length did not influence the ISQ value at all observation points. Our results suggest that submerging implant more inside bone may only influence primary stability. Moreover, the implant diameter and site of placement influence primary and secondary stability before loading, whereas the implant length does not when its diameter is not accounted for.

Increased responses in the somatosensory thalamus immediately after spinal cord injury.

Alonso-Calviño, E; Martínez-Camero, I; Fernández-López, E; Humanes-Valera, D; Foffani, G; Aguilar, J

2016-03-01

Spinal cord injury (SCI) involves large-scale deafferentation of supraspinal structures in the somatosensory system, producing well-known long-term effects at the thalamo-cortical level. We recently showed that SCI provokes immediate changes in cortical spontaneous and evoked responses and here, we have performed a similar study to define the immediate changes produced in the thalamic ventro-postero-lateral nucleus (VPL) that are associated with the forepaw and hindpaw circuits. Extracellular electrophysiological recordings from the VPL reflected the spontaneous activity and the responses to peripheral electrical stimulation applied to the paws. Accordingly, the activity of the neuronal populations recorded at specific thalamic locations that correspond to the forepaw and hindpaw circuits was recorded under control conditions and immediately after thoracic SCI. The results demonstrate that peripheral inputs from both extremities overlap on neuronal populations in the somatosensory thalamus. In addition, they show that the responses of thalamic neurons to forepaw and hindpaw stimuli are increased immediately after SCI, in association with a specific decrease in spontaneous activity in the hindpaw locations. Finally, the increased thalamic responses after SCI have a state-dependent component in relation with cortical activity. Together, our results indicate that the thalamic changes occurring immediately after SCI could contribute to the cortical changes also detected immediately after such spinal lesions.

Park, Miran; Kim, Dosoo; Ahn, Kangmo

2014-01-01

Purpose There are scanty epidemiologic data on the prevalence of food allergy (FA) among preschool children in Asia. We performed this study to determine the prevalence and causative foods of immediate-type FA in early childhood in Korea. Methods A questionnaire-based, cross-sectional study was performed between September and October 2011. Children aged 0-6 years were recruited from 301 public child care centers in Seoul. Parents were asked to complete a questionnaire on FA. Children with FA were classified into "perceived FA, ever," "immediate-type FA, ever," and "immediate-type FA, current" according to the algorithm. Results A total of 16,749 children were included in this study. The prevalence of "perceived FA, ever," "immediate-type FA, ever," and "immediate-type FA, current" was 15.1%, 7.0%, and 3.7%, respectively. "Immediate-type FA, current" was reported by 182 (4.9%) out of 3,738 children aged ≤2 years, 262 (3.4%) of 7,648 children aged 3-4 years, and 177 (3.3%) of 5,363 children aged 5-6 years. Hen's egg (126/621) was the most frequent cause as the individual food item, followed by cow's milk (82/621) and peanut (58/621). Among the food groups, fruits (114/621), tree nuts (90/621) and crustaceans (85/621) were the most common offending foods. The three leading causes of food-induced anaphylaxis were hen's egg (22/47), cow's milk (15/47), and peanut (14/47). Conclusions The prevalence of immediate-type FA in early childhood is 3.7%, and is higher in younger children. The most common offending foods differed with age. PMID:24587949

The risk of perioperative bleeding is high in patients who take aspirin and clopidogrel after a percutaneous coronary intervention, and whether to stop the drugs is a matter of concern for dentists. The aim of this study was to answer the specific question: should aspirin and clopidogrel bisulphate (Plavix®) be discontinued during a conventional forceps extraction? We studied 64 patients during the first year after percutaneous insertion of coronary stents who were taking aspirin (ASA) 80mg and clopidogrel (Plavix(®)) 75mg, and 50 healthy patients who were to have a conventional forceps extraction at this polyclinic in 2013-2014 and acted as controls. Clinical details (underlying diseases; number of roots; type of tooth; type of haemostasis; and bleeding immediately, 30minutes, and 48hours after intervention) were compared. We evaluated 114 patients with the mean (range) age of 56 (43-76) years, and there were no significant differences in demographic data, underlying diseases, type of tooth, number of roots, and dose of anaesthetic between the groups. There were also no significant differences in the number of bleeds immediately and 30minutes after intervention (P=0.310 and 0.205). The time that the last dose of aspirin had been taken correlated with 30-minute haemostasis (20 compared with 12hours, p=0.037). During the 48hours after the intervention, there were no uncontrolled bleeds or emergency referrals. We conclude that using aspirin and Plavix® simultaneously has no considerable effect on the risk of bleeding in patients having conventional forceps extraction of a single tooth.

Nonexpansive immediate breast reconstruction using human acellular tissue matrix graft (AlloDerm).

PubMed

Salzberg, C Andrew

2006-07-01

Immediate breast reconstruction has become a standard of care following mastectomy for cancer, largely due to improved esthetic and psychologic outcomes achieved with this technique. However, the current historical standards--transverse rectus abdominis myocutaneous flap reconstruction and expander--implant surgery-still have limitations as regards patient morbidity, short-term body-image improvements, and even cost. To address these shortcomings, we employ a novel concept of human tissue replacement to enhance breast shape and provide total coverage, enabling immediate mound reconstruction without the need for breast expansion prior to permanent implant placement. AlloDerm (human acellular tissue matrix) is a human-derived graft tissue with extensive experience in various settings of skin and soft tissue replacement surgery. This report describes the success using acellular tissue matrix to provide total coverage over the prosthesis in immediate reconstruction, with limited muscle dissection. In this population, 49 patients (76 breasts) successfully underwent the acellular tissue matrix-based immediate reconstruction, resulting in durable breast reconstruction with good symmetry. These findings may predict that acellular tissue matrix-supplemented immediate breast reconstruction will become a new technique for the immediate reconstruction of the postmastectomy breast.

2017-12-01

This retrospective study aimed to analyse the fate of the buccal crest after immediate implant placement (IIP) through the use of cone beam computed tomography (CBCT). In 16 consecutive patients, an implant was placed in a more palatal position after extraction, thereby creating a gap of at least 2mm between the implant and the buccal crest. Subsequently, this gap was filled with a bone substitute. Preoperatively, immediate postoperatively, and late postoperatively, a CBCT was made to measure the thickness of the buccal crest. After application of the bone substitute, the buccal crest increased in thickness from 0.9mm to 2.4mm (mean). At a mean of 103 weeks after IIP, late postoperative CBCT scans showed that the thickness of the buccal crest was compacted to 1.8mm. In the same period, the height of the buccal crest increased by 1.6mm (mean) to, on average, 1.2mm above the implant shoulder. The aesthetic outcome was analysed using the White and Pink Esthetic Score (WES and PES). Both scored high: 8.4 and 11.8, respectively. Within the limitations of this study, the results of this IIP protocol are promising. Long-term prospective research on this topic on a large number of patients is necessary.

Immediate versus one-month wet storage fatigue of restorative materials.

PubMed

Gladys, S; Braem, M; Van Meerbeek, B; Lambrechts, P; Vanherle, G

1998-03-01

Immediate finishing is a highly desirable property of restorative materials. In general, the resin composites, the polyacid-modified resin composites and resin-modified glass-ionomers are finished immediately after light-curing. For the conventional glass-ionomers a waiting period of 24 h is recommended. Therefore, the objective of this study was to investigate whether immediate finishing and application of cyclic loading under water spray on resin-modified glass-ionomers, a conventional glass-ionomer, a polyacid-modified resin composite and a resin composite are reflected in their Young's modulus and fatigue resistance after 1-month wet storage compared with a control group that could mature untroubled for 1 month. From this study, it could be concluded that there is a material-dependent response on immediate finishing. For the conventional glass-ionomer, the waiting period of 24 h is highly advisable. The resin composite suffered more than the other test materials. A second statement is that one must be cautious by the extrapolation of findings obtained on quasi static tests (Young's modulus) towards dynamic properties (flexural fatigue limit).

We describe a female previously diagnosed of primary antiphospholipid antibody syndrome who presented a preclampsia in the second pregnancy. An urgent caesaria was made because of a worsening high blood pressure and oliguria. In the immediated puerperium she showed low platelets and persistent high blood pressure. Afterwards acute renal failure and neurological signs with a severe aortic valvulopathy were diagnosed. An haemolytic anemia was also detected. Definitive diagnosis was made by kidney biopsy with the result of a thrombotic microangiopathy. Treatment with low weight heparin and aspirin and systemic corticosteroids was started in the immediate puerperium and fresh frozen plasma was then added with a good response to treatment. Actually she is still with high blood pressure, aortic valvulopathy. Renal function is normal one year later.

To evaluate the esthetic outcomes of immediate single-tooth implant restoration in anterior maxilla with the pink esthetic score (PES). Nine patients were treated with 9 Straumann implants by immediate single-tooth implant restoration in anterior maxilla. Assessment of PES after crown placement at 1 week (baseline) and 6 months after implantation was conducted. Statistical analysis was performed using SPSS 16.0 software package. Nine implants achieved a retention rate of 100%. PES for single-tooth implant was 10.33 ± 1.50 at 1 week and 11.44 ± 0.88 at 6 months after crown placement. The difference was significant(P=0.021). This study indicates that immediate single-tooth implant restoration in anterior maxilla is predictable. Immediate single-tooth implantation can result in good clinical esthetic results in most patients with single-tooth missing in anterior maxilla.

Immediate loading protocols for the rehabilitation of edentulous or partially edentulous patients have become very popular, due to the conveniences they afford in comparison with conventional loading techniques. A preliminary study was carried out with 8 patients subjected to dental implant treatment with an immediate loading protocol involving a novel system of abutments with flexible screws. Implant survival was analyzed, together with marginal bone loss and patient and dentist satisfaction. A total of 35 implants were subjected to immediate loading using the abutments with flexible screws. The mean patient and dentist satisfaction score was 9.1 and 8.5, respectively. After 12 months the dental implant survival rate was 95.8%, with a mean marginal bone loss of 0.51 ± 0.12 mm. The novel system of abutments with flexible screws offers a good alternative to conventional immediate loading, since it allows rapid and simple manufacture of a reliable passive fit, fixed interim prosthesis after surgery. Key words: Dental implants, Flexafit®, Immediate loading, Immediate prosthesis.

The place of care in ethical theory.

PubMed

Veatch, R M

1998-04-01

The concept of care and a related ethical theory of care have emerged as increasingly important in biomedical ethics. This essay outlines a series of questions about the conceptualization of care and its place in ethical theory. First, it considers the possibility that care should be conceptualized as an alternative principle of right action; then as a virtue, a cluster of virtues, or as a synonym for virtue theory. The implications for various interpretations of the debate of the relation of care and justice are then explored, suggesting three possible meanings for that contrast. Next, the possibility that care theorists are taking up the debate over the relation between principles and cases is considered. Finally, it is suggested that care theorists may be pressing for consideration of an entirely new question in moral theory: the assessment of the normative appropriateness of relationships. Issues needing to be addressed in an ethic of relationships are suggested.

Case of immediate hypersensitivity to beer.

2016-06-01

We report here a case of immediate hypersensitivity to beer, in which a female patient developed angioedema of the eyelids shortly after consuming beer. In skin prick tests, the patient showed positive reactions to the base ingredients of beer, particularly malt and barley. The specific serum immunoglobulin E antibodies against barley and malt displayed weakly positive reactivity. To identify the immunoreactive antigens, malt and barley proteins were separated by 2-D polyacrylamide gel electrophoresis and immunoreacted with the patient's serum. The results of mass spectrometric analysis revealed that the main antigen was a protein with similarity to protein z-type serpin. Notably, the identified antigen had a molecular weight of 20-25 kDa, which is markedly smaller than that previously reported for protein Z4 (44 kDa). Taken together, these analyses indicate that a possible new antigen which belongs to the protein Z family elicits immediate hypersensitivity to beer. © 2015 Japanese Dermatological Association.

Whose Sense of Place? Re-thinking Place Concept and Urban Heritage Conservation in Social Media Era

Dameria, Christin; Akbar, Roos; Natalivan Indradjati, Petrus

2018-05-01

A change in a conservation approach that is now more focused on the conservation of a place than on a single object has placed an understanding of a place as an important concept that must be understood in urban heritage planning. However, the urban place perspective has been shifted, as a result of the change of attitude of people living in the urban area due to the rising of social media. This paper argues the concept of place in the heritage conservation planning, especially in the area designed to be tourism objects, which needs to be revisited. The very dynamic urban people as a result of technology and information must be considered. In order to understand the man-place relationship, the sense of place concept is the most common concept used and in the current context of heritage conservation, the review of place concept could be traced by understanding who is the owner of a sense of place in the social media era. In the current academic literature, the common discourse says the local community as the owner of the sense of place because visitors have limited chance to own the sense of place. This paper also argues that the shift of place perspective due to social media could be the catalyst in creating a strong sense of place for visitors. To support the argument, this paper uses the study of Concept of Mediatization and Concept of Parochial that have successfully explained how social media provides indirect experience based on people-place interaction and a sense of familiarity of an unknown or strange place. Therefore, this paper states that in the sense of place context: (1) the experience factor, as one of the factors in the creation of a sense of place, does not need to be physically experienced but it can be built based on other person’s personal reflection. It also gives an opportunity to make a self-interpretation about the value of the heritage place; (2) sense of familiarity, which is believed to be owned by the locals only due to the period of

Efficient k-Winner-Take-All Competitive Learning Hardware Architecture for On-Chip Learning

PubMed Central

Ou, Chien-Min; Li, Hui-Ya; Hwang, Wen-Jyi

2012-01-01

A novel k-winners-take-all (k-WTA) competitive learning (CL) hardware architecture is presented for on-chip learning in this paper. The architecture is based on an efficient pipeline allowing k-WTA competition processes associated with different training vectors to be performed concurrently. The pipeline architecture employs a novel codeword swapping scheme so that neurons failing the competition for a training vector are immediately available for the competitions for the subsequent training vectors. The architecture is implemented by the field programmable gate array (FPGA). It is used as a hardware accelerator in a system on programmable chip (SOPC) for realtime on-chip learning. Experimental results show that the SOPC has significantly lower training time than that of other k-WTA CL counterparts operating with or without hardware support.

Biomedical gait evaluation of the immediate effect of orthotic treatment for flexible flat foot.

PubMed

Leung, A K; Mak, A F; Evans, J H

1998-04-01

Flexible flat foot subjects attending the prosthetics and orthotics units come with prescriptions from orthopaedic surgeons for arch supports. Usually a pair of thermoformed plastic inserts are fabricated and fitted to treat the patients. However the effect of the orthotic treatment is not yet clear. A motion analysis system with two video cameras placed on the lateral and rear sides of the subject together with one force platform was used to investigate the immediate effects of the orthotic treatment. The force platform collected force data and the two cameras captured two-dimensional displacement data of the lower limb. Eight subjects, all having an arch index (AI) larger than 3.0 participated in the study. For each subject, three successful steps on the force platform were videotaped for both the shod (with shoe only) and the orthotic (with shoe and orthosis) conditions. The kinetic variables were normalized to individual body weight and averaged for each subject. A Paired t-test was conducted to analyse sample means of matched pairs between the shod and the orthotic conditions. The results showed changes in displacement data with relatively little change in the collected force data. The modified UCBL shoe insert evaluated significantly affected the orientation and movements of the subtalar joint, ankle joint and knee joint. These immediate effects reduced the degree and duration of abnormal pronation during the stance phase and thus had the potential for decreasing strain in the plantar ligaments and reducing abnormal tibial rotation which may be therapeutic for the foot.

Immediate neonatal outcome in pregnancies complicated by placenta previa is largely dependent on gestational age. We aimed to investigate whether placenta previa increases the risk for perinatal mortality and immediate morbidity of the offspring born at term. A population-based cohort study included all singleton pregnancies, with and without placenta previa, delivered at term. Maternal and pregnancy characteristics as well as immediate neonatal morbidity and mortality were compared. Deliveries occurred between the years 1991-2013 in a tertiary medical center. Multiple pregnancies, and fetal congenital malformations were excluded. During the study period 233,123 consecutive term deliveries met the inclusion criteria; 0.2 % of the babies were born to mothers diagnosed with placenta previa. Women with placenta previa were significantly older and more likely to have had a previous cesarean section. Pregnancies were more likely to be complicated with pathological presentations and cesarean hysterectomies. Babies born at term following pregnancies with placenta previa were more likely to weigh less than 2500 g (OR 2.78 CI 1.9-3.9, p < 0.001). However, 5 min Apgar score and perinatal mortality rates were comparable between the groups. Neonatal outcomes remained comparable between the groups in a sub-analysis of cesarean deliveries only. Although placenta previa pregnancies involve higher maternal morbidity rates, term offsprings are not at an increased risk for immediate adverse outcome.

Discussions of the hippocampus often focus on place cells, but many neurons are not place cells in any given environment. Here we describe the collective activity in such mixed populations, treating place and non-place cells on the same footing. We start with optical imaging experiments on CA1 in mice as they run along a virtual linear track and use maximum entropy methods to approximate the distribution of patterns of activity in the population, matching the correlations between pairs of cells but otherwise assuming as little structure as possible. We find that these simple models accurately predict the activity of each neuron from the state of all the other neurons in the network, regardless of how well that neuron codes for position. Our results suggest that understanding the neural activity may require not only knowledge of the external variables modulating it but also of the internal network state.

Objectives The aim of this clinical study was to evaluate a new type of prefabricated bar system, supported by axial and tilted implants at 5-year follow-up. Materials and Methods Twenty-nine consecutive participants (19 females, 10 males) (mean age 61.4 years), edentulous in one or both jaws, with severe atrophy of the posterior regions, were treated according to the All-on-four® protocol with immediately loaded axial (64) and tilted (64) implants supporting complete-arch screw-retained prostheses (12 maxillary, 20 mandibular) featuring a prefabricated bar as framework. Follow-up visits were performed at 3, 6, 12, 24, 48, and 60 months after implant insertion. Radiographic assessments were made using panoramic radiographs obtained immediately after surgery and at each follow-up visit. Bone level measurements around the axial and tilted implants were compared by means of the Student's t-test. Results One axial implant failed in the lower jaw and did not compromise prosthetic function. The 60-month overall implant survival rate was 100% for axially positioned implants and 98.44% for tilted implants. The implant survival rates were 100% in the maxilla and 98.75% in the mandible. None of the 32 fixed prostheses were lost during the observation period, representing a prosthetic survival rate of 100%. No statistically significant differences (P > 0.05) in marginal bone loss between tilted and axial implants were detected in either jaw over time. Conclusions The use of the evaluated prefabricated bar for immediately loaded implants placed according to the All-on-four concept may significantly reduce implant failures; however, more long-term prospective clinical trials are needed to affirm the effectiveness of the surgical-prosthetic protocol.

To describe the visual outcomes of three patients who had LASIK flap buttonhole and were treated immediately with photorefractive keratectomy (PRK) and topical mitomycin C (MMC) 0.02%. Three patients underwent bilateral LASIK with the SCHWIND Carriazo-Pendula 90 microm head microkeratome. In all three cases, a buttonhole flap occurred in the left eye. The flap was repositioned and phototherapeutic keratectomy for 50 microm was used for epithelial removal while immediate PRK with MMC was performed to treat the buttonhole flap. Three months after the procedure, uncorrected distance visual acuity and corrected distance visual acuity were 20/20 with regular topographic findings. Using PRK with MCC immediately after the occurrence of the LASIK flap buttonhole may be an effective treatment.

The aim of this paper was to study the healing of 1-1.4 mm wide buccal defects at implants placed immediately into extraction sockets (IPIES) filled with a mixture of synthetic hydroxyapatite (HA) 60% and beta-tricalciumphosphate (TCP) 40% or left with the clot alone and both covered with collagen membranes. Eight Labrador dogs were used and implants were placed immediately into the extraction sockets of the first molar bilaterally. A mixture of synthetic HA 60% and beta-TCP 40% at the test or the clot alone at the control sites were used to fill the defects. All surgical sites were subsequently covered by a resorbable collagen membrane and a non-submerged healing was allowed. After 4 months, the animals were euthanized, biopsies harvested and processed for histomorphometric analysis. At the time of installation, residual buccal defects occurred that were 1.1 mm and 1.4 mm wide and 3 mm and 4 mm deep at the control and test sites, respectively. After 4 months of healing, the top of the bony crest and the coronal level of osseointegration were located respectively at 0.1 ± 1.8 mm and 1.5 ± 1.8 mm at the test, and 0.6 ± 1.6 mm and 1.2 ± 0.7 mm at the control sites apically to the implant shoulder. Bone-to-implant contact at the buccal aspect was 34.9 ± 25.9% and 36.4 ± 17.3% at the test and control sites, respectively. No statistically significant differences were found between test and control sites for any of the variables analyzed at the buccal aspects. The use of a mixture of synthetic HA 60% and beta-TCP 40% to fill residual buccal defects 1-1.4 mm wide at IPIES did not improve significantly the results of healing. © 2015 Wiley Periodicals, Inc.

This study evaluated the 1-year survival and success rate of root-analogue direct laser metal sintering (DLMS) implants, placed into the extraction sockets of 15 patients. DLMS is a technology which allows solids with complex geometry to be fabricated by annealing metal powder microparticles in a focused laser beam, according to a computer-generated three-dimensional (3D) model; the fabrication process involves the laser-induced fusion of titanium microparticles, in order to build, layer-by-layer, the desired object. Cone-beam computed tomography (CBCT) acquisition and 3D image conversion, combined with the DLMS process, allow the fabrication of custom-made, root-analogue implants (RAIs). CBCT images of 15 non-restorable premolars (eight maxilla; seven mandible) were acquired and transformed into 3D models: from these, custom-made, root-analogue DLMS implants with integral abutment were fabricated. Immediately after tooth extraction, the RAIs were placed in the sockets and restored with a single crown. One year after implant placement, clinical and radiographic parameters were assessed: success criteria included absence of pain, suppuration, and exudation; absence of implant mobility and absence of continuous peri-implant radiolucency; distance between the implant shoulder and the first visible bone-to-implant contact <1.5 mm from initial surgery; and absence of prosthetic complications. At the 1-year follow-up, no implants were lost, for a survival rate of 100 %. All implants were stable, with no signs of infection. The good conditions of the peri-implant tissues were confirmed by the radiographic examination, with a mean DIB of 0.7 mm (±0.2). The possibility of fabricating custom-made, RAI DLMS implants opens new interesting horizons for immediate placement of dental implants.

Dying at a favorite place is one of the important determinants for terminally ill cancer patients. The primary aim was to clarify (1) differences in preferred place of care and place of death among the general public across four areas across Japan and (2) preferred place of care and place of death among community-representative cancer patients. A cross-sectional mail survey was conducted on 8,000 randomly selected general population. We examined preferred place of care and place of death using two vignettes and obtained a total of 3,984 (50%) responses. For the pain scenario, approximately 50% of the general public throughout four areas chose home as their preferred place of care; and for the dependent-without-pain scenario, about 40% chose home as preferred place of care. In cancer patients, for both scenarios, approximately 40% chose home as the preferred place of care, and they were significantly less likely to choose home. The most preferred combination of place of care and place of death was home hospice for both groups. Although there were statistically significant differences in preferred place of care and place of death among the four regions, the absolute difference was less than 8%. Independent determinants of choosing home as place of care included concern about family burden and being unable to adequately respond to sudden changes out of working hours. In conclusion, establishing more accessible home and hospice service is strongly required through arranging regional resources to reduce family burden, alleviating patient-perceived burdens, and improving 24-h support at home.

Background Immediate loading protocols for the rehabilitation of edentulous or partially edentulous patients have become very popular, due to the conveniences they afford in comparison with conventional loading techniques. Material and Methods A preliminary study was carried out with 8 patients subjected to dental implant treatment with an immediate loading protocol involving a novel system of abutments with flexible screws. Implant survival was analyzed, together with marginal bone loss and patient and dentist satisfaction. Results A total of 35 implants were subjected to immediate loading using the abutments with flexible screws. The mean patient and dentist satisfaction score was 9.1 and 8.5, respectively. After 12 months the dental implant survival rate was 95.8%, with a mean marginal bone loss of 0.51 ± 0.12 mm. Conclusions The novel system of abutments with flexible screws offers a good alternative to conventional immediate loading, since it allows rapid and simple manufacture of a reliable passive fit, fixed interim prosthesis after surgery. Key words:Dental implants, Flexafit®, Immediate loading, Immediate prosthesis. PMID:29410752

A study was performed to determine whether cigarettes were smoked more intensely outside of public venues in Scotland, compared to indoors, after introduction of the public place smoking (PPS) ban. It was conducted in three waves: before the ban, immediately after and 6 months after introduction. The study included 322 regular smokers of four cigarette brand variants. Filter analysis measurements were used to estimate the human-smoked yields of tar and nicotine from cigarettes smoked predominantly inside (before the ban) or outside (after the ban) public venues. Self-reported cigarette consumption data were also collected. Numbers of cigarettes smoked indoors in public places fell dramatically after the ban. There was a corresponding rise in smoking incidence in outdoor public locations. The ban did not significantly affect the total number of cigarettes smoked by the subjects over the weekends investigated. Human-smoked yields of tar and nicotine decreased slightly after the introduction of the ban and some reductions were significant. Therefore, smoking outdoors at public venues, following the PPS ban, did not increase smoking intensity. Any changes in smoking behaviour that may have occurred had little effect on mainstream smoke exposure or cigarette consumption for those that continued to smoke. Copyright © 2010 Elsevier Inc.

Purpose Prior studies reported homeless adolescents engage in more sexual risk than their housed peers. However, these comparisons are typically made post hoc by comparing homeless adolescent community-based samples with high school probability samples. This study utilizes a random sample of high school students to examine homelessness experiences and sexual risk behaviors. Methods A supplemental survey to the Youth Risk Behavior Survey containing questions regarding homelessness and sexual health was administered to Los Angeles high school students (N=1,839). Multivariate logistic regressions assessed the associations between demographics, past year homelessness experiences (i.e., place of nighttime residence), and being sexually active and condom use at last intercourse. Results Homelessness experiences consisted of staying in a shelter (10.4%), a public place (10.1%), and with a stranger (5.6%). Lesbian, gay, bisexual, transgender, questioning (LGBTQ), younger, and male adolescents were more likely to experience homelessness. LGBTQ adolescents were also more likely to report staying with a stranger and less likely to report staying in a shelter. Compared to adolescents who stayed in shelters, adolescents who stayed with strangers and in public places were more likely to engage in unprotected sex at last intercourse. Conclusions Adolescents who report sexual activity and sexual risk taking are more likely to report homelessness experiences. With regard to sexual health, staying with strangers could be a particularly risky form of homelessness; LGBTQ and Black adolescents are more likely to experience this form of homelessness. Efforts to reduce homelessness and sexual risk-taking need to recognize the specific vulnerabilities faced by these populations. PMID:23360897

Background and aims There is a previous evidence for impulsivity in individuals with Internet and Video Gaming Disorders. The aim of this study was to examine whether Internet and video game addictions are associated with experiential delay discounting, risk-taking, and sensitivity to social rejection using computerized tasks and questionnaires. Methods Twenty participants (mean age 24, SD = 1.55) with high score on the Problematic Online Gaming Questionnaire (POGQ) were compared with 20 participants (mean age 24.8, SD = 1.34) with low score on the POGQ. They performed on computerized Balloon Analog Risk Task and Experiential Delay discounting Task (EDT), and filled in the sensitivity to social rejection questionnaire. Results Participants with high POGQ scores had lower measures of delay discounting, higher measures of risk-taking, and higher measures of sensitivity to social rejection compared with participants with low POGQ scores. Discussion The results of this study support the previous evidence of risk-taking and provide new evidence for difficulties in delay discounting and sensitivity to social rejection among those who score high on Internet and video games. Conclusions The results suggest that Internet- and video game-addicted individuals seek immediate gratification and cannot wait for later reward. Furthermore, these individuals spend time in the virtual world, where they feel safe, and avoid social interactions presumably due to fears of social rejection.

Dynamic NMDAR-mediated properties of place cells during the object place memory task.

N-methyl-D-aspartate receptors (NMDAR) in the hippocampus participate in encoding and recalling the location of objects in the environment, but the ensemble mechanisms by which NMDARs mediate these processes have not been completely elucidated. To address this issue, we examined the firing patterns of place cells in the dorsal CA1 area of the hippocampus of mice (n = 7) that performed an object place memory (OPM) task, consisting of familiarization (T1), sample (T2), and choice (T3) trials, after systemic injection of 3-[(±)2-carboxypiperazin-4yl]propyl-1-phosphate (CPP), a specific NMDAR antagonist. Place cell properties under CPP (CPP-PCs) were compared to those after control saline injection (SAL-PCs) in the same mice. We analyzed place cells across the OPM task to determine whether they signaled the introduction or movement of objects by NMDAR-mediated changes of their spatial coding. On T2, when two objects were first introduced to a familiar chamber, CPP-PCs and SAL-PCs showed stable, vanishing or moving place fields in addition to changes in spatial information (SI). These metrics were comparable between groups. Remarkably, previously inactive CPP-PCs (with place fields emerging de novo on T2) had significantly weaker SI increases than SAL-PCs. On T3, when one object was moved, CPP-PCs showed reduced center-of-mass (COM) shift of their place fields. Indeed, a subset of SAL-PCs with large COM shifts (>7 cm) was largely absent in the CPP condition. Notably, for SAL-PCs that exhibited COM shifts, those initially close to the moving object followed the trajectory of the object, whereas those far from the object did the opposite. Our results strongly suggest that the SI changes and COM shifts of place fields that occur during the OPM task reflect key dynamic properties that are mediated by NMDARs and might be responsible for binding object identity with location.

The aim of this study was to describe the meaning of the father's lived experiences when taking care of his infant as the primary caregiver during the first hours after birth, when the infant was apart from the mother due to the mother's postoperative care. Fifteen fathers were interviewed between 8 days and 6 weeks after the birth. The results describe a movement toward father-child togetherness characterized by an immediate and gradual change within the father as he undertakes increasing responsibility while getting to know his child. The results can be discussed in antenatal classes in order to integrate the father's important role in the care of his infant, especially in a situation where the mother-infant dyad has been interrupted.

2014-07-01

Hypersensitivity reactions including anaphylaxis have been reported for nearly all classes of therapeutic reagents and these reactions can occur within minutes to hours of exposure. These reactions are unpredictable, not directly related to dose or the pharmacological action of the drug and have a relatively high mortality risk. This review will focus on the clinical presentation, immune mechanisms, diagnosis and prevention of the most serious form of immediate onset drug hypersensitivity reaction, anaphylaxis. The incidence of drug-induced anaphylaxis deaths appears to be increasing and our understanding of the multiple and complex reasons for the unpredictable nature of anaphylaxis to drugs is also expanding. This review highlights the importance of enhancing our understanding of the biology of the patient (i.e. immune response, genetics) as well as the pharmacology and chemistry of the drug when investigating, diagnosing and treating drug hypersensitivity. Misdiagnosis of drug hypersensitivity leads to substantial patient risk and cost. Although oral provocation is often considered the gold standard of diagnosis, it can pose a potential risk to the patient. There is an urgent need to improve and standardize diagnostic testing and desensitization protocols as other diagnostic tests currently available for assessment of immediate drug allergy are not highly predictive. © 2013 The British Pharmacological Society.

Modafinil restores methamphetamine induced object-in-place memory deficits in rats independent of glutamate N-methyl d-aspartate receptor expression

PubMed Central

Reichel, Carmela M.; Gilstrap, Meghin G.; Ramsey, Lauren A.; See, Ronald E.

2013-01-01

Background Chronic methamphetamine (meth) abuse in humans can lead to various cognitive deficits, including memory loss. We previously showed that chronic meth self-administration impairs memory for objects relative to their location and surrounding objects. Here, we demonstrate that the cognitive enhancer, modafinil, reversed this cognitive impairment independent of glutamate N-methyl d-aspartate (GluN) receptor expression. Methods Male, Long-Evans rats underwent a noncontingent (Experiment 1) or contingent (Experiment 2) meth regimen. After one week of abstinence, rats were tested for object-in-place recognition memory. Half the rats received either vehicle or modafinil (100 mg/kg) immediately after object familiarization. Rats (Experiment 2) were sacrificed immediately after the test and brain areas that comprise the key circuitry for object in place performance were manually dissected. Subsequently, glutamate receptor expression was measured from a crude membrane fraction using western blot procedures. Results Saline-treated rats spent more time interacting with the objects in changed locations, while meth-treated rats distributed their time equally among all objects. Meth-treated rats that received modafinil showed a reversal in the deficit, whereby they spent more time exploring the objects in the new locations. GluN2B receptor subtype was decreased in the perirhinal cortex, yet remained unaffected in the prefrontal cortex and hippocampus of meth rats. This meth-induced down regulation occurred whether or not meth experienced rats received vehicle or modafinil. Conclusions These data support the use of modafinil for memory impairment in meth addiction. Further studies are needed to elucidate the neural mechanisms of modafinil reversal of cognitive impairments. PMID:24120858

Don't wait to incubate: immediate versus delayed incubation in divergent thinking.

2012-08-01

Previous evidence for the effectiveness of immediate incubation in divergent creative tasks has been weak, because earlier studies exhibited a range of methodological problems. This issue is theoretically important, as a demonstration of the effects of immediate incubation would strengthen the case for the involvement of unconscious work in incubation effects. For the present experiment, we used a creative divergent-thinking task (alternative uses) in which separate experimental groups had incubation periods that were either delayed or immediate and that consisted of either spatial or verbal tasks. Control groups were tested without incubation periods, and we carried out checks for intermittent conscious work on the target task during the incubation periods. The results showed significant incubation effects that were stronger for immediate than for delayed incubation. Performance was not different between the verbal and spatial incubation conditions, and we found no evidence for intermittent conscious working during the incubation periods. These results support a role for unconscious work in creative divergent thinking, particularly in the case of immediate incubation.

Effects of benefits and harms on older persons' willingness to take medication for primary cardiovascular prevention.

Quality-assurance initiatives encourage adherence to evidenced-based guidelines based on a consideration of treatment benefit. We examined older persons' willingness to take medication for primary cardiovascular disease prevention according to benefits and harms. In-person interviews were performed with 356 community-living older persons. Participants were asked about their willingness to take medication for primary prevention of myocardial infarction (MI) with varying benefits in terms of absolute 5-year risk reduction and varying harms in terms of type and severity of adverse effects. Most (88%) would take medication, providing an absolute benefit of 6 fewer persons with MI out of 100, approximating the average risk reduction of currently available medications. Of participants who would not take it, 17% changed their preference if the absolute benefit was increased to 10 fewer persons with MI, and, of participants who would take it, 82% remained willing if the absolute benefit was decreased to 3 fewer persons with MI. In contrast, large proportions (48%-69%) were unwilling or uncertain about taking medication with average benefit causing mild fatigue, nausea, or fuzzy thinking, and only 3% would take medication with adverse effects severe enough to affect functioning. Older persons' willingness to take medication for primary cardiovascular disease prevention is relatively insensitive to its benefit but highly sensitive to its adverse effects. These results suggest that clinical guidelines and decisions about prescribing these medications to older persons need to place emphasis on both benefits and harms.

To describe the meals consumed by adults living in a midsize city in the South of Brazil, according to the place and preparation. A population-based cross-sectional study was conducted in Pelotas, Southern Brazil, in 2012. The two-stage sampling design used the 2010 census tracts as primary sampling units. Data were collected on the place of meals (at home or out) and on the kind of preparations consumed at home (homemade, snacks, take away food) covering the two days prior to the interview, using a standardized questionnaire. The study included 2,927 adults, of which 59.0% were female, 60.0% were below 50 years of age and 58.0% were in work. Data were collected on 11,581 meals consumed on the two days preceding the interview, 25.0% were consumed outside of the home at lunchtime, and 10.0% at dinnertime. Considering home meals, most participants reported eating food prepared at home at both lunch and dinner. The majority of out-of-home meals (64.0% for lunch and 61.0% for dinner) were consumed in the work place, mostly based on food prepared at home. Individuals eating out of home were mostly male, young and highly educated. The occupational categories that ate at restaurants more often were trade workers, businessmen, teachers and graduate professionals. Despite the changes in eating patterns described in Brazil in recent years, residents of medium-sized towns still mostly eat at home, consuming homemade food.

2001-09-01

To compare outcomes of open reduction and internal fixation of displaced mandible fractures followed by either immediate mobilization or 2 weeks of mandibular-maxillary fixation. A prospective, randomized, single-blinded study was performed. The study was performed between January 1, 1997, and March 30, 2000. Inclusion criteria were displaced fractures between the mandibular angles, age greater than 16 years, and no involvement of the alveolus, ramus, condyles, or maxilla. All fractures were repaired by means of open reduction and internal fixation using 2.0-mm titanium plates secured either in transoral fashion or percutaneously. Data were collected at 6-week and 3- and 6-month postoperative examinations. Variables were assessed by a surgeon blinded to the history of immobilization and included pain, malunion or nonunion, occlusion, trismus, wound status, infection rates, dental hygiene, and weight loss. Twenty-nine consecutive patients were enrolled, 16 patients to immediate function and 13 patients to 2 weeks of mandibular-maxillary fixation. No statistically significant differences were found between groups for any of the variables. Immediate release and temporary immobilization showed mean weight loss of 10 and 8 pounds and trismus of 4.2 and 4.6 cm, respectively. One wound separation and one infection were seen in the immobilization population, and no wound separation or infection was seen in the immediate-release group. Dental hygiene was similar between the groups. No malunion or nonunion was noted in either group. In this prospective and randomized study, no significant differences were noted between the groups receiving either immediate release or 2 weeks of mandibular-maxillary fixation. The findings support the treatment of selective mandible fractures with 2.0-mm miniplates and immediate mobilization.

Tactile modulation of hippocampal place fields.

PubMed

Gener, Thomas; Perez-Mendez, Lorena; Sanchez-Vives, Maria V

2013-12-01

Neural correlates of spatial representation can be found in the activity of the hippocampal place cells. These neurons are characterized by firing whenever the animal is located in a particular area of the space, the place field. Place fields are modulated by sensory cues, such as visual, auditory, or olfactory cues, being the influence of visual inputs the most thoroughly studied. Tactile information gathered by the whiskers has a prominent representation in the rat cerebral cortex. However, the influence of whisker-detected tactile cues on place fields remains an open question. Here we studied place fields in an enriched tactile environment where the remaining sensory cues were occluded. First, place cells were recorded before and after blockade of tactile transmission by means of lidocaine applied on the whisker pad. Following tactile deprivation, the majority of place cells decreased their firing rate and their place fields expanded. We next rotated the tactile cues and 90% of place fields rotated with them. Our results demonstrate that tactile information is integrated into place cells at least in a tactile-enriched arena and when other sensory cues are not available.

To compare the outcome of immediately loaded single implants with a machined or a roughened surface. Fifty patients had two implant sites randomly allocated to receive flaplessplaced single Syra implants (Sweden & Martina), one with a machined and one with a roughened surface (sand-blasted with zirconia powder and acid etched), according to a split-mouth design. To be loaded immediately, implants had to be inserted with a torque superior to 50 Ncm. Implants were restored with definitive crowns in direct occlusal contact within 48 h. Patients were followed for 6 months after loading. Outcome measures were prosthetic and implant failures and complications. Two machined implants and four roughened implants were not loaded immediately. Six months after loading no dropout occurred. One implant loaded late, which had a rough implant surface, failed 20 days after loading (P (McNemar test) = 0.625; difference in proportions = -0.04; 95% CI: -0.15 to 0.07). Three crowns had to be remade on machined implants and four on roughened implants (P (McNemar test) = 1.000; difference in proportions = -0.02; 95% CI: -0.12 to 0.08). Three machined and five roughened implants experienced complications (P (McNemar test) = 0.625; difference in proportions = -0.04; 95% CI: -0.15 to 0.07). There were no statistically significant differences between groups for crown and implant losses as well as complications. Up to 6 months after loading both machined and roughened flapless-placed and immediately loaded single implants provided good and similar results, however, longer follow-ups are needed to evaluate the long-term prognosis of implants with different surfaces.

Critical review of immediate implant loading.

Gapski, Ricardo; Wang, Hom-Lay; Mascarenhas, Paulo; Lang, Niklaus P

2003-10-01

Implant dentistry has become successful with the discovery of the biological properties of titanium. In the original protocol, studies have advocated a 2-stage surgical protocol for load-free and submerged healing to ensure predictable osseointegration. However, the discomfort, inconvenience, and anxiety associated with waiting period remains a challenge to both patients and clinicians. Hence, loading implant right after placement was attempted and has gained popularity among clinicians. Issues/questions related to this approach remain unanswered. Therefore, it is the purpose of this review article to (1). review and analyze critically the current available literature in the field of immediate implant loading and (2). discuss, based on scientific evidence, factors that may influence this treatment modality. Literature published over the past 20 years was selected and reviewed. Findings from these studies were discussed and summarized in the tables. The advantages and disadvantages associated with immediate implant loading were analyzed. Factors that may influence the success of immediate implant loading, including patient selection, type of bone quality, required implant length, micro- and macrostructure of the implant, surgical skill, need for achieving primary stability/control of occlusal force, and prosthesis guidelines, were thoroughly reviewed and discussed. Various studies have demonstrated the feasibility and predictability of this technique. However, most of these articles are based on retrospective data or uncontrolled cases. Randomized, prospective, parallel-armed longitudinal human trials are primarily based on short-term results and long-term follow-ups are still scarce in this field. Nonetheless, from available literature, it may be concluded that anatomic locations, implant designs, and restricted prosthetic guidelines are key to ensure successful outcomes. Future studies, preferably randomized, prospective longitudinal studies, are certainly needed

It is well known that peripheral nerve injury should be treated immediately in the clinic, but in some instances, repair can be delayed. This study investigated the effects of immediate versus delayed (3 days after injury) neurorrhaphy on repair of transected sciatic nerve in New Zealand rabbits using stereological, histomorphological and biomechanical methods. At 8 weeks after immediate and delayed neurorrhaphy, axon number and area in the sciatic nerve, myelin sheath and epineurium thickness, Schwann cell morphology, and the mechanical property of nerve fibers did not differ obviously. These results indicate that delayed neurorrhaphy do not produce any deleterious effect on sciatic nerve repair. PMID:25206663

2016-11-01

Principles of aging-in-place emphasize the importance of creating sustainable environments that enable older people to maintain a sense of belonging, autonomy, independence, safety and security. Simply altering the built environment is insufficient for creating more inclusive environments for older persons, as creating 'meaningful' places for aging involves consideration of psychosocial and cultural issues that go beyond issues of physical space. This paper illustrates how applications of community-based participatory research methods, in particular, participatory community mapping workshops (PCMWs), can be used to access experiences of place, identify facilitators and barriers to accessing the built environment and co-create place-based solutions among older people and service providers in a new affordable housing development in Western Canada. Founded on tenets of empowerment and relationship building, four PCMWs were undertaken with 54 participants (N = 38 older people; N = 16 local service providers). PCMWs comprised (i) experiential group walks around the community to access understandings of place and community and (ii) mapping exercises, whereby participants articulated their place-based needs within the context of the new affordable housing development and surrounding neighbourhood. Dialogues were digitally recorded, transcribed and thematically analysed. Visual data, including photographs taken during experiential group walks were categorized and integrated into the narrative to illustrate place meanings. PCMWs enabled senior housing and social care professionals and decision-makers to co-construct knowledge with older tenants that facilitated place action and change. Key themes identified by participants included: identifying services and needs for health and wellbeing, having opportunities for social participation and overcoming cross-cultural challenges. PCMWs were found to be a nuanced method of identifying needs and resources and generating

Sex and estrous cycle differences in immediate early gene activation in the hippocampus and the dorsal striatum after the cue competition task.

The hippocampus and dorsal striatum are important structures involved in place and response learning strategies respectively. Both sex and estrous cycle phase differences in learning strategy preference exist following cue competition paradigms. Furthermore, significant effects of sex and learning strategy on hippocampal neural plasticity have been reported. However, associations between learning strategy and immediate early gene (IEG) expression in the hippocampus and dorsal striatum are not completely understood. In the current study we investigated the effects of sex and estrous cycle phase on strategy choice and IEG expression in the hippocampus and dorsal striatum of rats following cue competition training in the Morris water maze. We found that proestrous rats were more likely to choose a place strategy than non-proestrous or male rats. Although male cue strategy users travelled greater distances than the other groups on the first day of training, there were no other sex or strategy differences in the ability to reach a hidden or a visible platform. Female place strategy users exhibited greater zif268 expression and male place strategy users exhibited greater cFos expression compared to all other groups in CA3. Furthermore, cue strategy users had greater expression of cFos in the dorsal striatum than place strategy users. Shorter distances to reach a visible platform were associated with less activation of cFos in CA3 and CA1 of male place strategy users. Our findings indicate multiple differences in brain activation with sex and strategy use, despite limited behavioral differences between the sexes on this cue competition paradigm.

Placing the power of real options analysis into the hands of natural resource managers - taking the next step.

Nelson, Rohan; Howden, Mark; Hayman, Peter

2013-07-30

This paper explores heuristic methods with potential to place the analytical power of real options analysis into the hands of natural resource managers. The complexity of real options analysis has led to patchy or ephemeral adoption even by corporate managers familiar with the financial-market origins of valuation methods. Intuitively accessible methods for estimating the value of real options have begun to evolve, but their evaluation has mostly been limited to researcher-driven applications. In this paper we work closely with Bush Heritage Australia to evaluate the potential of real options analysis to support the intuitive judgement of conservation estate managers in covenanting land with uncertain future conservation value due to climate change. The results show that modified decision trees have potential to estimate the option value of covenanting individual properties while time and ongoing research resolves their future conservation value. Complementing this, Luehrman's option space has potential to assist managers with limited budgets to increase the portfolio value of multiple properties with different conservation attributes.

With an increase in life expectancy in 'developed' countries, the number of elderly patients receiving joint injections for arthritis is increasing. There are legitimate concerns about an increased risk of thromboembolism if anticoagulation is stopped or reversed for such an injection. Despite being a common dilemma, the literature on this issue is scarce. We undertook 2,084 joint injections of the knee and shoulder in 1,714 patients between August 2008 and December 2013. Within this cohort, we noted 41 patients who were taking warfarin and followed them immediately after joint injection in the clinic or radiology department, looking carefully for complications. Then, we sought clinical follow-up, correspondence, and imaging evidence for 4 weeks, looking for complications from these joint injections. We recorded International Normalised Ratio (INR) values before injection. No complications were associated with the procedure after any joint injection. The radiologists who undertook ultrasound-guided injections to shoulders re-scanned the joints looking for haemarthroses: they found none. A similar outcome was noted clinically after injections in the outpatient setting. With a mean INR of 2.77 (range, 1.7-5.5) and a maximum INR within this group of 5.5, joint injections to the shoulder and knee can be undertaken safely in primary or secondary care settings despite the patient taking warfarin.

Immediate effect of a functional wrist orthosis for children with cerebral palsy or brain injury: A randomized controlled trial.

2017-10-28

Two-group randomized controlled trial. Upper limb orthoses worn during functional tasks are commonly used in pediatric neurologic rehabilitation, despite a paucity of high-level evidence. The purpose of this study was to investigate if a customized functional wrist orthosis, when placed on the limb, leads to an immediate improvement in hand function for children with cerebral palsy or brain injury. A 2-group randomized controlled trial involving 30 children was conducted. Participants were randomized to either receive a customized functional wrist orthosis (experimental, n = 15) or not receive an orthosis (control, n = 15). The box and blocks test was administered at baseline and repeated 1 hour after experimental intervention, with the orthosis on if randomized to the orthotic group. After intervention, there were no significant differences on the box and blocks test between the orthotic group (mean, 10.13; standard deviation, 11.476) and the no orthotic group (mean, 14.07; standard deviation, 11.106; t[28], -0.954; P = .348; and 95% confidence interval, -12.380 to 4.513). In contrast to the findings of previous studies, our results suggest that a functional wrist orthosis, when supporting the joint in a 'typical' position, may not lead to an immediate improvement in hand function. Wearing a functional wrist orthosis did not lead to an immediate improvement in the ability of children with cerebral palsy or brain injury to grasp and release. Further research is needed combining upper limb orthoses with task-specific training and measuring outcomes over the medium to long term. Copyright © 2017 Hanley & Belfus. All rights reserved.

To evaluate the soft tissue and the dimensional changes of the alveolar bony crest at sites where deproteinized bovine bone mineral (DBBM) particles, concomitantly with the placement of a collagen membrane, were used at implants installed into sockets immediately after tooth extraction. The pulp tissue of the mesial roots of (3) P(3) was removed in six Labrador dogs, and the root canals were filled. Flaps were elevated bilaterally, the premolars hemi-sectioned, and the distal roots removed. Recipient sites were prepared in the distal alveolus, and implants were placed. At the test sites, DBBM particles were placed in the residual marginal defects concomitantly with the placement of a collagen membrane. No treatment augmentation was performed at the control sites. A non-submerged healing was allowed. Impressions were obtained at baseline and at the time of sacrifice performed 4 months after surgery. The cast models obtained were analyzed using an optical system to evaluate dimensional variations. Block sections of the implant sites were obtained for histological processing and soft tissue assessments. After 4 months of healing, no differences in soft tissue dimensions were found between the test and control sites based on the histological assessments. The location of the soft tissue at the buccal aspect was, however, more coronal at the test compared with the control sites (1.8 ± 0.8 and 0.9 ± 0.8 mm, respectively). At the three-dimensional evaluation, the margin of the soft tissues at the buccal aspect appeared to be located more apically and lingually. The vertical dislocation was 1 ± 0.6 and 2.7 ± 0.5 mm at the test and control sites, respectively. The area of the buccal shrinkage of the alveolar crest was significantly smaller at the test sites (5.9 ± 2.4 mm(2) ) compared with the control sites (11.5 ± 1.7 mm(2) ).

2010-01-01

Deferred imitation has long held a privileged position in early cognitive development, considered an early marker of representational thought with links to language development and symbolic processes. Children with autism have difficulties with several abilities generally thought to be related to deferred imitation: immediate imitation, language, and symbolic play. However, few studies have examined deferred imitation in early autism. The present study examined both deferred, spontaneous imitation and immediate, elicited imitation on a set of carefully matched tasks in 36 young children with autism: 16 with early onset autism, 20 with regressive autism and two contrast groups, younger typically developing children (n = 20) and age matched children with significant developmental delays (n = 21). Analyses of co-variance controlling for differences in verbal mental age revealed significant main effects for task, but no main effect of group and no interaction of task by group. Deferred imitation scores were lower than immediate imitation scores for all groups. Imitation performance was related to overall intellectual functioning for all groups, and there were moderate and significant relations between imitation in the immediate elicited condition and in the spontaneous deferred condition for all groups. Finally, there were no differences between onset subgroups in imitation scores, suggesting that the two share a similar phenotype involving both types of imitation. PMID:18221343

Melt-processed polymeric cellular dosage forms for immediate drug release.

PubMed

Blaesi, Aron H; Saka, Nannaji

2015-12-28

The present immediate-release solid dosage forms, such as the oral tablets and capsules, comprise granular matrices. While effective in releasing the drug rapidly, they are fraught with difficulties inherent in processing particulate matter. By contrast, liquid-based processes would be far more predictable; but the standard cast microstructures are unsuited for immediate-release because they resist fluid percolation and penetration. In this article, we introduce cellular dosage forms that can be readily prepared from polymeric melts by incorporating the nucleation, growth, and coalescence of microscopic gas bubbles in a molding process. We show that the cell topology and formulation of such cellular structures can be engineered to reduce the length-scale of the mass-transfer step, which determines the time of drug release, from as large as the dosage form itself to as small as the thickness of the cell wall. This allows the cellular dosage forms to achieve drug release rates over an order of magnitude faster compared with those of cast matrices, spanning the entire spectrum of immediate-release and beyond. The melt-processed polymeric cellular dosage forms enable predictive design of immediate-release solid dosage forms by tailoring microstructures, and could be manufactured efficiently in a single step.

Moving Beyond 'Aging In Place' to Understand Migration and Aging: Place Making and the Centrality Of Occupation.

Johansson, Karin; Rudman, Debbie Laliberte; Mondaca, Margarita; Park, Melissa; Luborsky, Mark; Josephsson, Staffan; Asaba, Eric

2013-04-01

'Aging in place' has become a key conceptual framework for understanding and addressing place within the aging process. However, aging in place has been critiqued for not sufficiently providing tools to understand relations or transactions between aging and place, and for not matching the diversity of contemporary society in which people are moving between and across nations more than ever before. In this article, the authors draw from concepts of place and migration that are becoming increasingly visible in occupational science. The concept of 'aging in place' is critically examined as an example of an ideal where the understanding of place is insufficiently dynamic in a context of migration. The authors suggest that the concept of place making can instead be a useful tool to understand how occupation can be drawn upon to negotiate relationships that connect people to different places around the world, how the negotiated relations are embedded within the occupations that fill daily lives, and how this process is contextualized and enacted in relation to resources and capabilities.

Involvement of Histamine and RhoA/ROCK in Penicillin Immediate Hypersensitivity Reactions.

The mechanism of penicillin immediate hypersensitivity reactions has not been completely elucidated. These reactions are generally considered to be mediated by IgE, but penicillin-specific IgE could not be detected in most cases. This study demonstrated that penicillin was able to cause vascular hyperpermeability in a mouse model mimicking clinical symptoms of penicillin immediate hypersensitivity reactions. The first exposure to penicillin also induced immediate edema and exudative reactions in ears and lungs of mice in a dose-dependent manner. Vasodilation was noted in microvessels in ears. These reactions were unlikely to be immune-mediated reactions, because no penicillin-specific IgE was produced. Furthermore, penicillin treatment directly elicited rapid histamine release. Penicillin also led to F-actin reorganization in human umbilical vein endothelial cells and increased the permeability of the endothelial monolayer. Activation of the RhoA/ROCK signaling pathway was observed in ears and lungs of mice and in endothelial cells after treatment with penicillin. Both an anti-histamine agent and a ROCK inhibitor attenuated penicillin immediate hypersensitivity reactions in mice. This study presents a novel mechanism of penicillin immediate hypersensitivity reactions and suggests a potential preventive approach against these reactions.

These reactions were unlikely to be immune-mediated reactions, because no penicillin-specific IgE was produced. Furthermore, penicillin treatment directly elicited rapid histamine release. Penicillin also led to F-actin reorganization in human umbilical vein endothelial cells and increased the permeability of the endothelial monolayer. Activation of the RhoA/ROCK signaling pathway was observed in ears and lungs of mice and in endothelial cells after treatment with penicillin. Both an anti-histamine agent and a ROCK inhibitor attenuated penicillin immediate hypersensitivity reactions in mice. This study presents a novel mechanism of penicillin immediate hypersensitivity reactions and suggests a potential preventive approach against these reactions. PMID:27619816

The aim of this systematic review and meta-analysis was to compare the survival rate of the implants and the peri-implant tissue changes associated with implants inserted in fresh extraction sockets and those inserted in healed sockets. This review has been registered at PROSPERO under the number CRD42016043309. A systematic search was conducted by two reviewers independently in the databases PubMed/MEDLINE, Embase, and the Cochrane Library using different search terms; articles published until November 2016 were searched for. The searches identified 30 eligible studies. A total of 3,049 implants were installed in a total of 1,435 patients with a mean age of 46.68 years and a minimum of 6 months of follow-up. The survival rate of delayed implants (98.38%) was significantly greater than immediate implants (95.21%) (p=.001). For the marginal bone loss (p=.32), implant stability quotients values (p=.44), and pocket probing depth (p=.94) there was no significant difference between the analysed groups. The immediate implants placed in fresh sockets should be performed with caution because of the significantly lower survival rates than delayed implants inserted in healed sockets.

We describe the rationale and protocol for a randomized controlled trial (RCT) to assess whether intrauterine contraception placed immediately after a second trimester abortion will result in fewer pregnancies than current recommended practice of intended placement at 4 weeks post-abortion. Decision analysis suggests the novel strategy could substantially reduce subsequent unintended pregnancies and abortions. This paper highlights considerations of design, implementation and evaluation of a trial expected to provide rigorous evidence for appropriate insertion timing and health economics of intrauterine contraception after second trimester abortion. Consenting women choosing to use intrauterine contraception after abortion for a pregnancy of 12 to 24 weeks will be randomized to insertion timing groups either immediately (experimental intervention) or four weeks (recommended care) post abortion. Primary outcome measure is pregnancy rate at one year. Secondary outcomes include: cumulative pregnancy rates over five year follow-up period, comprehensive health economic analyses comparing immediate and delayed insertion groups, and device retention rates, complication rates (infection, expulsion) and, contraceptive method satisfaction. Web-based Contraception Satisfaction Questionnaires, clinical records and British Columbia linked health databases will be used to assess primary and secondary outcomes. Enrolment at all clinics in the province performing second trimester abortions began in May 2010 and is expected to complete in late 2011. Data on one year outcomes will be available for analysis in 2014. The RCT design combined with access to clinical records at all provincial abortion clinics, and to information in provincial single-payer linked administrative health databases, birth registry and hospital records, offers a unique opportunity to evaluate such an approach by determining pregnancy rate at one through five years among enrolled women. We highlight

A food environments feedback system (FoodBack) for empowering citizens and change agents to create healthier community food places.

This study developed a systems-based approach (called FoodBack) to empower citizens and change agents to create healthier community food places. Formative evaluations were held with citizens and change agents in six diverse New Zealand communities, supplemented by semi-structured interviews with 85 change agents in Auckland and Hamilton in 2015-2016. The emerging system was additionally reviewed by public health experts from diverse organizations. A food environments feedback system was constructed to crowdsource key indicators of the healthiness of diverse community food places (i.e. schools, hospitals, supermarkets, fast food outlets, sport centers) and outdoor spaces (i.e. around schools), comments/pictures about barriers and facilitators to healthy eating and exemplar stories on improving the healthiness of food environments. All the information collected is centrally processed and translated into 'short' (immediate) and 'long' (after analyses) feedback loops to stimulate actions to create healthier food places. FoodBack, as a comprehensive food environment feedback system (with evidence databases and feedback and recognition processes), has the potential to increase food sovereignty, and generate a sustainable, fine-grained database of food environments for real-time food policy research. © The Author 2017.

Differential vulnerability to the punishment of cocaine related behaviours: effects of locus of punishment, cocaine taking history and alternative reinforcer availability.

PubMed

Pelloux, Yann; Murray, Jennifer E; Everitt, Barry J

2015-01-01

The availability of alternative reinforcement has been shown to reduce drug use, but it remains unclear whether it facilitates a reduction or cessation of drug seeking or taking. We compared the effects of punishment of cocaine seeking or taking behaviour after brief or extended cocaine-taking histories when behavioural reallocation was facilitated or not by making available an alternative ingestive reinforcer (sucrose). In the first experiment, punishment of either seeking or taking responses was introduced immediately after training on the seeking-taking chained schedule. In the second experiment, punishment of cocaine seeking was introduced after 12 additional days of either 1 or 6 h daily access to cocaine self-administration. In both experiments, beginning 1 week before the introduction of punishment, a subset of rats had concurrent nose poke access to sucrose while seeking or taking cocaine. The presence of an alternative source of reinforcement markedly facilitated behavioural reallocation from punished cocaine taking after acquisition. It also facilitated punishment-induced suppression of cocaine seeking after an extensive cocaine self-administration history likely by prompting goal-directed motivational control over drug use. However, a significant proportion of rats were deemed compulsive-maintaining drug use after an extensive cocaine history despite the presence of abstinence-promoting positive and negative incentives. Making available an alternative reinforcer facilitates disengagement from punished cocaine use through at least two different processes but remains ineffective in a subpopulation of vulnerable animals, which continued to seek cocaine despite the aversive consequence of punishment and the presence of the alternative positive reinforcer.

Case reports suggest that children with food-triggered atopic dermatitis (AD) on elimination diets may develop immediate reactions on accidental ingestion or reintroduction of an avoided food. The objective of this study was to systematically study the incidence and risk factors associated with these immediate reactions. A retrospective chart review of 298 patients presenting to a tertiary-care allergy-immunology clinic based on concern for food-triggered AD was performed. Data regarding triggering foods, laboratory testing, and clinical reactions were collected prospectively from the initial visit. Food-triggered AD was diagnosed by an allergist-immunologist with clinical evaluation and laboratory testing. We identified immediate reactions as any reaction to a food for which there was evidence of sIgE and for which patients developed timely allergic signs and symptoms. Differences between children with and without new immediate reactions were determined by a Mann-Whitney, χ(2), or Fisher's exact test as appropriate. A total of 19% of patients with food-triggered AD and no previous history of immediate reactions developed new immediate food reactions after initiation of an elimination diet. Seventy percent of reactions were cutaneous but 30% were anaphylaxis. Cow's milk and egg were the most common foods causing immediate-type reactions. Avoidance of a food was associated with increased risk of developing immediate reactions to that food (P < .01). Risk was not related to specific IgE level nor a specific food. A significant number of patients with food-triggered AD may develop immediate-type reactions. Strict elimination diets need to be thoughtfully prescribed as they may lead to decreased oral tolerance.

Singh, Payal; Nagpal, Rajni; Singh, Udai Pratap

2017-08-01

This in vitro study evaluated the effect of dentin biomodifiers on the immediate and long-term bond strengths of a simplified etch and rinse adhesive to dentin. Flat coronal dentin surfaces were prepared in 120 extracted human molars. Teeth were randomly divided into 5 groups ( n = 24) according to 5 different surface pre-treatments: No pre-treatment (control); 1M carbodiimide (EDC); 0.1% epigallocatechin-3-gallate (EGCG); 2% minocycline (MI); 10% sodium ascorbate (SA). After surface pre-treatment, adhesive (Adper Single Bond 2 [SB], 3M ESPE) was applied. Composite was applied into transparent plastic tubes (2.5 mm in diameter), which was placed over the bonded dentin surface. From each group, 10 samples were subjected to shear bond strength (SBS) evaluation at 24 hours (immediate) and remaining 10 samples were tested after 6 months (delayed). Additionally, 4 samples per group were subjected to scanning electron microscopic analysis for observation of resin-dentin interface. The data were statistically analysed with Shaperio‑Wilk W test, 2-way analysis of variance (ANOVA), and post hoc Tukey's test. At 24 hours, SBS of all surface pre-treatment groups were comparable with the control group, with significant differences found between EDC and SA groups only ( p = 0.009). After 6 months storage, EDC, EGCG, and MI pre-treatments preserved the resin-dentin bond strength with no significant fall. Dentin pre-treatment with all the dentin biomodifiers except SA resulted in significant preservation of resin-dentin bond over 6 months storage period, without negatively affecting the immediate bond strength of the etch and rinse adhesive tested.

Immediate sensitivity to structural constraints in pronoun resolution

PubMed Central

Chow, Wing-Yee; Lewis, Shevaun; Phillips, Colin

2014-01-01

Real-time interpretation of pronouns is sometimes sensitive to the presence of grammatically-illicit antecedents and sometimes not. This occasional sensitivity has been taken as evidence that structural constraints do not immediately impact the initial antecedent retrieval for pronoun interpretation. We argue that it is important to separate effects that reflect the initial antecedent retrieval process from those that reflect later processes. We present results from five reading comprehension experiments. Both the current results and previous evidence support the hypothesis that agreement features and structural constraints immediately constrain the antecedent retrieval process for pronoun interpretation. Occasional sensitivity to grammatically-illicit antecedents may be due to repair processes triggered when the initial retrieval fails to return a grammatical antecedent. PMID:25018739

2011-01-01

Objective: Use of bedside emergency department (ED) ultrasound has become increasingly important for the clinical practice of emergency medicine (EM). We sought to evaluate differences in the availability of immediate bedside ultrasound based on basic ED characteristics and physician staffing. Methods: We surveyed ED directors in all 351 EDs in Colorado, Georgia, Massachusetts, and Oregon between January and April 2009. We assessed access to bedside ED ultrasound by the question: “Is bedside ultrasound available immediately in the ED?” ED characteristics included location, visit volume, admission rate, percent uninsured, total emergency physician full-time equivalents and proportion of EM board-certified (BC) or EM board-eligible (BE) physicians. Data analysis used chi-square tests and multivariable logistical regression to compare differences in access to bedside ED ultrasound by ED characteristics and staffing. Results: We received complete responses from 298 (85%) EDs. Immediate access to bedside ultrasound was available in 175 (59%) EDs. ED characteristics associated with access to bedside ultrasound were: location (39% for rural vs. 71% for urban, P<0.001); visit volume (34% for EDs with low volume [<1 patient/hour] vs. 79% for EDs with high volume [≥3 patients/hour], P<0.001); admission rate (39% for EDs with low [0–10%] admission rates vs. 84% for EDs with high [>20%] rates, P<0.001); and EM BC/BE physicians (26% for EDs with a low percentage [0–20%] vs.74% for EDs with a high percentage [≥80%], P<0.001). Conclusion: U.S. EDs differ significantly in their access to immediate bedside ultrasound. Smaller, rural EDs and those staffed by fewer EM BC/BE physicians more frequently lacked access to immediate bedside ultrasound in the ED. PMID:21691479

Sensitization to gelatin in children with systemic non-immediate-type reactions to varicella vaccines.

2000-03-01

We recently found that four children who experienced systemic immediate-type reactions to varicella vaccine with gelatin had anti-gelatin IgE. We also found systemic non-immediate-type allergic reactions, which mainly consist of systemic cutaneous signs, appearing several hours or more after the vaccination. To investigate the relationship between immune responses to gelatin and non-immediate-type reactions to gelatin-containing varicella vaccines, we measured anti-gelatin IgE and IgG in the sera of the children with these allergic reactions. Serum samples were taken from 21 children who showed non-immediate-type reactions to varicella vaccines. As a positive control, serum samples were taken from 33 children who showed immediate-type reactions to varicella vaccine and had anti-gelatin IgE. As a negative control, serum samples were taken from 50 children who showed no reaction to the vaccine. We then examined anti-gelatin IgE and IgG in sera of the children. Of 21 children with non-immediate-type reactions, two (10%) had anti-gelatin IgE and six (29%) had anti-gelatin IgG. In the positive control group, all 33 children with immediate-type reactions had anti-gelatin IgG as well as IgE. In the negative control group, all 50 children who showed no allergic reaction to varicella vaccines had neither anti-gelatin IgE nor IgG. These results suggest that the possibility exists that some non-immediate-type reactions to varicella vaccine are caused by immune reactions to gelatin.

Psychosocial correlates of immediate versus delayed reconstruction of the breast.

Two groups of consecutive patients from two different plastic surgical practice populations were evaluated to determine psychosocial differences between those who underwent immediate (n = 25) versus delayed (n = 38) breast reconstruction. Psychological assessment consisted of a standardized symptom inventory (BSI) and a specially designed self-report questionnaire investigating reactions unique to mastectomy and reconstruction. Both groups were extremely equivalent with regard to sociodemographic data, with the typical subject being a well-educated and employed Caucasian wife. Verbal reports of physical complaints revealed no significant differences between the two groups except for difficulty with arm movement, which was statistically higher for the immediate group (p = 0.006.). This difference most likely was due to the axillary dissection being performed simultaneously at the time of reconstruction. The relationship between timing of reconstruction and self-reported distress over the mastectomy experience revealed that only 25 percent of the women who underwent immediate repair reported "high distress" in recalling their mastectomy surgery compared with 60 percent of the delayed reconstruction group (p = 0.02). In reference to the two scales measuring psychological symptoms, a general trend was present, with the delayed group scoring higher (although not statistically significantly) on 9 of our 12 scales. Ninety-six percent of the immediate group and 89 percent of the delayed group reported satisfaction with results.(ABSTRACT TRUNCATED AT 250 WORDS)

Re-engaging with places: Understanding bio-geo-graphical disruption and flow in adult brain injury survivors.

PubMed

Meijering, Louise; Theunissen, Nicky; Lettinga, Ant T

2018-05-05

Acquired Brain Injury (ABI) is one of the most common causes of disability and death in adults worldwide. After a period of rehabilitation, many ABI survivors still face complex mind/body conditions when they try to take up their former life again. Besides lasting visible impairments such as weakness and loss of body balance, there are often less obvious disabilities such as extreme fatigue, hypersensitivity for stimuli, memory, concentration and attention problems or personality changes. The aim of this paper is to understand how ABI survivors and their significant others renegotiate their engagements with everyday places, using the concepts of bio-geo-graphical disruption and flow. We conducted in-depth interviews and did a place-mapping exercise with 18 adult ABI survivors and their significant others. The data were analysed according to the principles of thematic analysis, with use of Atlas.ti. In the struggles of ABI survivors' relations with place, our findings show diversity in personal experiences and strategies, as well as commonalities at a more general level. First, having access to meaningful places, old and new, and coming to terms with the fact that some places may not be accessible anymore, appeared to be vital in the participants' process of healing. Second, the interplay or, as we call it, reciprocity, between different places can contribute to wellbeing: for instance, the security and continuity found at home may enable ABI survivors to handle a trip to a crowded city centre. Thus, by framing mind/body problems of ABI survivors in terms of a network of meaningful places rather than as a body with lost functions, our study shows how the reciprocity between multiple places has a potentially positive effect on life post-ABI.

2016-05-01

To better describe car-following behaviors in the adaptive cruise control strategy and further increase roadway traffic mobility and reduce fuel consumptions, the linkage between velocity fluctuation of the immediately ahead car and the following car's acceleration or deceleration is explored with respect to the measured car-following data by employing the gray correlation analysis theory and then an improved car-following model considering velocity fluctuation of the immediately ahead car on basis of the full velocity difference model is proposed. Numerical simulations are carried out and the effects of velocity fluctuation of the immediately ahead car on each car's velocity, acceleration, vehicular gap, fuel consumptions and the total fuel consumptions of the whole car-following system with different time window lengths are investigated in detail. The results show that velocity fluctuation of the immediately ahead car has significant effects on car-following behaviors and fuel consumptions, and that considering velocity fluctuation of the immediately ahead car in designing the adaptive cruise control system can improve traffic flow stability and reduce fuel consumptions.

The Cultural Boundaries of Perspective-Taking: When and Why Perspective-Taking Reduces Stereotyping.

Wang, Cynthia S; Lee, Margaret; Ku, Gillian; Leung, Angela K-Y

2018-06-01

Research conducted in Western cultures indicates that perspective-taking is an effective social strategy for reducing stereotyping. The current article explores whether and why the effects of perspective-taking on stereotyping differ across cultures. Studies 1 and 2 established that perspective-taking reduces stereotyping in Western but not in East Asian cultures. Using a socioecological framework, Studies 2 and 3 found that relational mobility, that is, the extent to which individuals' social environments provide them opportunities to choose new relationships and terminate old ones, explained our effect: Perspective-taking was negatively associated with stereotyping in relationally mobile (Western) but not in relationally stable (East Asian) environments. Finally, Study 4 examined the proximal psychological mechanism underlying the socioecological effect: Individuals in relationally mobile environments are more motivated to develop new relationships than those in relationally stable environments. Subsequently, when this motivation is high, perspective-taking increases self-target group overlap, which then decreases stereotyping.

In this work we perform direct single-shot readout of the singlet-triplet states in exchange coupled electrons confined to precision-placed donor atoms in silicon. Our method takes advantage of the large energy splitting given by the Pauli-spin blockaded (2,0) triplet states, from which we can achieve a single-shot readout fidelity of 98.4±0.2%. We measure the triplet-minus relaxation time to be of the order 3 s at 2.5 T and observe its predicted decrease as a function of magnetic field, reaching 0.5 s at 1 T.

Sorting of Marburg Virus Surface Protein and Virus Release Take Place at Opposite Surfaces of Infected Polarized Epithelial Cells

2001-01-01

Marburg virus, a filovirus, causes severe hemorrhagic fever with hitherto poorly understood molecular pathogenesis. We have investigated here the vectorial transport of the surface protein GP of Marburg virus in polarized epithelial cells. To this end, we established an MDCKII cell line that was able to express GP permanently (MDCK-GP). The functional integrity of GP expressed in these cells was analyzed using vesicular stomatitis virus pseudotypes. Further experiments revealed that GP is transported in MDCK-GP cells mainly to the apical membrane and is released exclusively into the culture medium facing the apical membrane. When MDCKII cells were infected with Marburg virus, the majority of GP was also transported to the apical membrane, suggesting that the protein contains an autonomous apical transport signal. Release of infectious progeny virions, however, took place exclusively at the basolateral membrane of the cells. Thus, vectorial budding of Marburg virus is presumably determined by factors other than the surface protein. PMID:11152500

To conduct an exploratory evaluation of the impact of the Arthritis Foundation's evidence-based Walk With Ease (WWE) program on work place activity limitations of adults with self-reported or doctor-diagnosed arthritis. WWE participants who were self-identified as "employed" completed the Workplace Activity Limitation Scale (WALS) at 6-week (postintervention; n = 94) and 1-year followup (n = 69). Paired t-tests were used to determine whether reduced work place limitations were reported at 6 weeks and maintained at 1-year followup. Participants were on average age 55 years, 88% women, and 61% white. The mean body mass index was 32 kg/m2 , and 81% had more than a high school education. Overall WALS scores improved significantly from a mean ± SD of 6.7 ± 3.99 at baseline to 5.5 ± 4.20 at 6-week followup (P < 0.001, effect size 0.30). Improvements were maintained at 1-year followup, i.e., no change from 6-week followup (P = 0.87). Work place activities reported by participants as "some" or "a lot" of difficulty at baseline, i.e., "crouch/bend/kneel/work in awkward positions," "stand for long periods," and "lift/carry/move objects," showed some of the highest improvements at 6 weeks. "Concentrate/keep your mind on the job" also improved significantly, although it was not rated as a substantial difficulty at baseline. Our study provides encouraging evidence that WWE, a brief, low-cost, and easy-to-do community-based walking program, may provide both immediate and sustained benefits for people with self-reported arthritis who also report a range of work place limitations related to their arthritis symptoms.

Oxidative damage has been implicated in pathogenesis of many diseases. It is known that various kinds of stresses accelerate the production of free radicals. As pregnancy being a physiological state accompanied by a high energy demand of many bodily functions and an increased oxygen requirement, increased level of oxidative stress would be expected. The present study was to elucidate the degree of oxidative stress during labour and immediately after delivery. Twenty healthy pregnant women and age matched and 20 healthy non-pregnant women were selected as subjects for this longitudinal study. Plasma malondialdehyde concentration was estimated as thiobarbituric acid reacting substances. A significant (p < 0.01) increase in plasma malondialdehyde concentration was noted in pregnant women during labour than in the non-pregnant women. Plasma malondialdehyde concentration was noted to increase with the progression and duration of labour to immediately following delivery. Labour being stressful state results in oxidative stress, which increased with increase in duration and progression of the labour till immediately following delivery.

Neuroimaging and Drug Taking in Primates Abbreviated title: Neuroimaging and Drug taking

Murnane, Kevin S.; Howell, Leonard L.

Rationale Neuroimaging techniques have led to significant advances in our understanding of the neurobiology of drug-taking and the treatment of drug addiction in humans. Neuroimaging approaches provide a powerful translational approach that can link findings from humans and laboratory animals. Objective This review describes the utility of neuroimaging toward understanding the neurobiological basis of drug taking, and documents the close concordance that can be achieved among neuroimaging, neurochemical and behavioral endpoints. Results The study of drug interactions with dopamine and serotonin transporters in vivo has identified pharmacological mechanisms of action associated with the abuse liability of stimulants. Neuroimaging has identified the extended limbic system, including the prefrontal cortex and anterior cingulate, as important neuronal circuitry that underlies drug taking. The ability to conduct within-subject, longitudinal assessments of brain chemistry and neuronal function has enhanced our efforts to document long-term changes in dopamine D2 receptors, monoamine transporters, and prefrontal metabolism due to chronic drug exposure. Dysregulation of dopamine function and brain metabolic changes in areas involved in reward circuitry have been linked to drug-taking behavior, cognitive impairment and treatment response. Conclusions Experimental designs employing neuroimaging should consider well-documented determinants of drug taking, including pharmacokinetic considerations, subject history and environmental variables. Methodological issues to consider include limited molecular probes, lack of neurochemical specificity in brain activation studies, and the potential influence of anesthetics in animal studies. Nevertheless, these integrative approaches should have important implications for understanding drug-taking behavior and the treatment of drug addiction. PMID:21360099
