Using Thermal Remote Sensing in Environmental Studies
Authors: Kubiak Marta , Dzieszko Piotr 
Published: August 2012

AbstractThermovision is a relatively new method of remote sensing with applications in areas such as military operations, residential monitoring, technological process control and emergency management. Surprisingly, it has not seen much application in environmental studies. The article presents a method of using thermovision for topoclimatic studies. The method is based on the spatial distribution of land surface temperature (LST). The LST distribution indicates the amount of solar energy reaching the Earth surface and depends primarily on terrain shape and land cover types. By analyzing the LST distribution, one can determine spatial topoclimatic variability. The LST derived topoclimatic classification was compared with the theoretical topoclimatic classification based on heat balance. New classes of topoclimates were created and some of the existing types were diversified into more detailed subtypes. The analysis of selected lowland areas in north‐western Poland revealed that both land cover and terrain shape characteristics had a significant impact on the LST distribution, contrary to the expectation of land cover characteristics being more important than terrain shape. The article demonstrates the possibilities of using thermovision in environmental research and presents a new method of topoclimate delimitation based on thermal remote sensing data and geographical information systems (GIS) techniques comparing. The LST classification method with conventional methods based on DEM and land cover analysis.
Diverse unity: creole contributions to interethnic integration in Guinea‐Bissau
Authors: Kohl Christoph 
Published: August 2012

AbstractThe paper explores how creole categories of people who have constituted a small but influential minority in Guinea‐Bissau for centuries contributed to a countrywide, integrated national culture since the eve of independence in 1974. Since independence, several cultural representations previously exclusive to creole communities have been – driven by the nationalist independence movement and the early postcolonial state – transformed into representations of a new national culture, crossing ethnic and religious boundaries. The fact that creole identity and culture had been transethnic – i.e. creole identity brings together individuals of heterogeneous cultural, ethnic and geographic descent – during the colonial period, has fostered in postcolonial times the countrywide spread of previously exclusively creole cultural features. I argue that this ‘transethnicisation’ of creole cultural representations has unified Bissau‐Guineans across ethnic lines, causing a strong commitment with their nation ‘from below’.

Background and aims:  The mother–infant relationship may represent a risk or a protective factor for child development. Hence, an early focus on the relationship may be a worthwhile preventive measure. A simple 10‐item instrument, the Mother and Baby Interaction Scale, could be a convenient screening instrument for early bonding failure. In this pilot study, preliminary indications of the internal consistency, stability, principal components validity of the Mother and Baby Interaction Scale were investigated.Methods:  Seventy‐six postpartum women participated. The Mother and Baby Interaction Scale and Postpartum Bonding Questionnaire were completed together with the Edinburgh Postnatal Depression Scale. The internal reliability of the Mother and Baby Interaction Scale, and its correlations with the Postpartum Bonding Questionnaire and Edinburgh Postnatal Depression Scale, was examined. Principal component analysis of the Mother and Baby Interaction Scale was conducted, and the emerging subscales were compared with the Postpartum Bonding Questionnaire.Results:  The principal component analysis yielded four subscales: Bonding problems, Worries about caretaking, Regulation and routine and Sensitivity and separation. We found acceptable internal consistency of the Mother and Baby Interaction Scale. The total score of the Mother and Baby Interaction Scale correlated better (r = 0.72) with the Postpartum Bonding Questionnaire than the four subscales. The correlation between the total scores of the Edinburgh Postnatal Depression Scale and the Mother And Baby Interaction Scale was r = 0.49.Conclusions:  The total score of the Mother and Baby Interaction Scale is a promising measure for early screening of the quality of the mother–infant relationship and is suitable for general practitioners, midwives and other health workers dealing with postpartum women and their children.

AbstractCardiovascular implantable electronic devices (CIEDs) are frequently utilized for management of cardiac dysrhythmias in patients with chronic kidney disease or end‐stage renal disease receiving hemodialysis. The survival benefit from use of implantable cardioverter defibrillators in patients with CKD or ESRD is not as clear as in the general population, particularly when used for primary prevention of sudden cardiac death. Transvenous CIED leads are associated with central vein stenosis resulting in significant adverse consequences for existing or future arteriovenous access. Venous hypertension from CIED lead‐related central vein stenosis is a challenging clinical problem and may require repeated percutaneous interventions, replacement of the CIED, or creation of alternative arteriovenous access. Infections associated with transvenous CIED leads are more frequent and associated with worse outcomes in patients with renal disease. Epicardial CIED leads or other nontransvenous devices may reduce complications of both central venous stenosis and endovascular infection in these vulnerable patients. Consensus recommendations are offered for avoidance and management of complications arising from the use of CIEDs and arteriovenous hemodialysis access.

AbstractArteriovenous fistula (AVF) nonmaturation is currently a significant clinical problem; however, the mechanisms responsible for this have remained unanswered. Previous work by our group and others has suggested that anatomical configuration and the corresponding hemodynamic endpoints could have an important role in AVF remodeling. Thus, our goal was to assess the longitudinal (temporal) effect of wall shear stress (WSS) on remodeling process of AVFs with two different configurations. The hypothesis is that early assessment of hemodynamic endpoints such as temporal gradient of WSS will predict the maturation status of AVF at later time points. Two AVFs with curved (C‐AVF) and straight (S‐AVF) configurations were created between the femoral artery and vein of each pig. Three pigs were considered in this study and in total six AVFs (three C‐AVF and three S‐AVF) were created. The CT scan and ultrasound were utilized to numerically evaluate local WSS at 20 cross‐sections along the venous segment of AVFs at 2D (D: days), 7D, and 28D postsurgery. These cross‐sections were located at 1.5 mm increments from the anastomosis junction. Local WSS values at these cross‐sections were correlated with their corresponding luminal area over time. The WSS in C‐AVF decreased from 22.3 ± 4.8 dyn/cm2 at 2D to 4.1 ± 5.1 dyn/cm2 at 28D, while WSS increased in S‐AVF from 13.0 ± 5.0 dyn/cm2 at 2D to 36.7 ± 5.3 dyn/cm2 at 28D. Corresponding to these changes in WSS levels, luminal area of C‐AVF dilated (0.23 ± 0.14 cm2 at 2D to 0.87 ± 0.14 cm2 at 28D) with attendant increase in flow rate. However, S‐AVF had minimal changes in area (0.26 ± 0.02 cm2 at 2D to 0.27 ± 0.03 cm2 at 28D) despite some increase in flow rate. Our results suggest that the temporal changes of WSS could have significant effects on AVF maturation. Reduction in WSS over time (regardless of initial values) may result in dilation (p < 0.05), while increase in WSS may be detrimental to maturation. Thus, creation of AVFs in a specific configuration which results in a decline in WSS over time may reduce AVF maturation failure.
Advances in Peritoneal Dialysis: A Review
Authors: Bargman Joanne M. 
Published: August 2012

AbstractPeritoneal dialysis (PD) is a simple, “low‐tech” form of renal replacement therapy that is less expensive than conventional in‐center hemodialysis in many parts of the world. Despite the advantages associated with this modality, it has not been as embraced as it deserves to be in many countries, including the United States. This brief review will focus on recent interesting and germane publications related to therapy with PD, centering on three broad themes: (i) “biocompatible” PD solutions; (ii) encapsulating peritoneal sclerosis; and (iii) comparisons of survival between PD and conventional hemodialysis. Recent publications concerning biocompatible solutions are hampered by varying trial designs, confounding by indication, and solutions with different compositions. Perhaps the most robust result, a reduction in peritonitis, has not been a consistent finding across studies. The results are generally disappointing with respect to clinically relevant endpoints such as membrane function and patient survival. The rarity of encapsulating peritoneal sclerosis, still a vexing and worrying complication, hampers any systematic examination of pathogenesis and treatment. The establishment of registries may help to better understand this condition. In the absence of randomized, controlled trials of PD versus hemodialysis, survival analyses are fraught with enormous methodological and statistical pitfalls. Nevertheless, many investigators remain focused on small differences in survival between the two modalities; even more inappropriately, some clinicians use these imperfect data to guide their modality recommendations. Recent outcome studies suggest that the survival of patients on PD compared with conventional hemodialysis is astonishingly similar, and differences between early and late survival are more explainable by the circumstances around initiation than by the modality itself.

AbstractObjectivesThe aim of this study was to determine variables associated with implant satisfaction and to evaluate the influence of peri‐implant mucosal level on implant satisfaction.Materials and MethodsForty patients restored with single‐tooth anterior maxillary implants were recruited for the study. The facial and inter‐proximal mucosal level of implants was measured. The patients and clinicians were asked to rate their satisfaction with dental implants on various aspects, using the visual analog scale (VAS). The VAS scores of patients and clinicians were compared and correlated. Variables associated with implant satisfaction as well as the influence of peri‐implant mucosal level on implant satisfaction were determined.ResultsThe patients showed high overall esthetic satisfaction (84.5%) with their implants. However, their satisfaction on the harmonization of gingiva (67.4%) was relatively low. The patient's overall esthetic satisfaction was significantly associated with crown color, crown shape, and confidence when smiling, but not the harmonization of gingival margin. The patient's satisfaction with the worth for expense was significantly associated with overall esthetic satisfaction, confidence when smiling, and speaking well. The presence of facial mucosal level ≥1 mm (compared with the contralateral tooth) and less than half papilla fill had no significant effect on the overall esthetic satisfaction assessed by patients. However, the presence of less than half papilla fill affected the patient's satisfaction on speech.ConclusionsPeri‐implant mucosal level is not a significant factor for the patient's esthetic satisfaction with their anterior maxillary implants. Papillary recession, however, appeared to affect their satisfaction on speech.

Published: August 2012

AbstractObjectivesThe aim of this study was to evaluate the extent and quality of new bone 6 months after sinus lift with biphasic micro‐ and macroporous calcium phosphate combined with fibrin sealant (MBCP‐FS) and the 1‐year implant success rate in the augmented site.Material and methodsMBCP‐FS was applied to one sinus in 96 subjects requiring augmentation for delayed dental implant placement. In subjects who required bilateral lifts (N = 33), the MBCP‐FS sinus was randomly selected; the contralateral sinus was grafted with autologous bone (mixed with Bio‐Oss when harvested bone volume was insufficient. Panoramic views were taken periodically prior to and up to 18 months post‐lift. Histomorphometric analysis was conducted on biopsies taken during implant placement 6 months after augmentation. Implant functionality and prosthesis success were assessed clinically 1 year after implant placement.ResultsIn MBCP‐FS sinuses, 20.6 ± 8.5% new, mainly lamellar bone was observed. Implants were placed as planned in 78/85 evaluable subjects (91.8%) 6 months after sinus lift. Graft heights remained stable 1 year after placement; 94.7% (142/150) of implants were functional. The amount and quality of new bone and implant success rates with MBCP‐FS were similar to autologous bone graft (mixed with Bio‐Oss in 30/31 evaluable subjects). MBCP‐FS was safe and well‐tolerated.ConclusionsMBCP‐FS is safe and effective in sinus floor elevation for dental implant placement, supporting bone regeneration and with high 1‐year implant success rates similar to autologous bone mixed with Bio‐Oss.

Published: August 2012

Background/PurposeFriction blisters on the foot are a debilitating pathology that have an impact on activities of daily living and can severely impair function. The purpose of this study was to test the hypotheses that digital infrared thermographic imaging will reveal: 1) a correlation between load application to the skin and the creation of blisters, and 2) a correlation between thermographic readings and contact thermometric temperatures.MethodsApparatus was developed to cause the formation of heel blisters through controlled load application (70 kPa). One foot of each of the 30 healthy volunteers (21 men and 9 women), with an age range of 31 ± 8 years, was subjected to load until a blister formed, after which load application ceased and temperature measurements were taken at set times during the following 5.5 h. Temperature measurements were also taken using a contact thermometer.ResultsThe majority of the participants (77%) blistered within 18 min of load application. All the blisters created showed significant increases in local temperature compared to baseline during blister creation (P < 0.001) and 30 min post‐blister creation (P < 0.001). There was a strong correlation between contact thermometry and thermographic temperature data (r > 8).ConclusionThese results suggest that thermographic images may prove useful for the remote assessment of traumatically damaged foot skin.
Both complete clearing and thinning of invasive trees lead to short‐term recovery of native riparian vegetation in theWesternCape,SouthAfrica

Published: August 2012

AbstractQuestionsMost rivers in theWesternCapeProvince ofSouthAfrica are heavily invaded by alien trees, often resulting in profound changes in biodiversity and ecosystem functioning. Although large‐scale management operations are underway to clear invasive trees and restore ecosystem function, little is known regarding native species recovery after alien clearing. HasEucalyptusinvasion along theBergRiver altered the distribution and composition of native vegetation? How does the removal of invasive trees through complete clearing and thinning facilitate the recovery of native vegetation?LocationBergRiver,WesternCape,SouthAfrica.MethodsWe assessed the recovery of native vegetation after 4 yr of complete clearing of the invasive treeEucalyptus camaldulensis(100% alien cover removal) and thinning (40–50% alien cover removal) along theBergRiver in theWesternCape,SouthAfrica. Native and alien plant cover, species richness and diversity were recorded on completely cleared and thinned sites and compared to natural (non‐invaded control sites) andE. camaldulensisinvaded sites.ResultsSpecies richness and diversity were significantly higher in both completely cleared and thinned sites compared to natural and invaded sites. Increases in species richness and diversity in completely cleared and thinned sites were a result of re‐invasion by alien herbaceous and graminoid species, which have the potential to hinder native species recovery. Cover of native trees and shrubs was higher in both completely cleared and thinned sites compared to invaded sites. Species composition (relative cover) in completely cleared and thinned sites was similar to species composition in natural sites.ConclusionsBoth complete clearing and thinning methods promote indigenous vegetation recovery and a positive trajectory towards recovery of ecosystem structure and composition can be expected in future. To improve management operations, a four‐stage thinning process that has the potential to facilitate native species recovery is suggested.
The Prevalence of Peyronie’s Disease in Japan: A Study in Men Undergoing Maintenance Hemodialysis and Routine Health Checks

Published: August 2012

ABSTRACT

Introduction
The incidence of Peyronie’s disease (PD) in the general population is believed to be as high as 20%. However, most of the data concerning the prevalence of PD have been obtained from Caucasian populations.

Aim
The aim of this study was to examine the prevalence of PD in Asia and among men undergoing hemodialysis and discuss the pathophysiology of PD.

Methods
A total of 1,090 men who received a routine health check at our hospital (control group) as well as 130 male patients undergoing maintenance hemodialysis were enrolled. The diagnosis of PD was based on a palpable penile plaque.

Main Outcome Measures
Hemodialysis patients were asked about their sexual activity and completed the International Index of Erectile Function-5 questionnaires. The differences between patients’ and hemodialysis-associated factors, comorbidities, and medications were statistically assessed for patients with and without PD.

Results
The prevalence of PD was significantly increased among hemodialysis patients (12 patients: 9.2%) relative the control group (six men: 0.6%) (P &lt; 0.0001, odds ratio: 18.4). In both groups, the plaques were primarily allocated dorsally. In the hemodialysis patients with PD, the frequency of masturbation (P &lt; 0.05) and the incidence of moderate or severe erectile dysfunction (P &lt; 0.01) were significantly higher than those among hemodialysis patients without PD. In comparison with patients without PD, the number of acetate dialysate users was significantly higher among patients with PD (P &lt; 0.05), and none of the PD patients used angiotensin-related antihypertensive drugs (P &lt; 0.05).

Conclusions
The prevalence of PD in healthy Japanese men is low (0.6%), which suggests the existence of racial differences in the prevalence of PD. Moreover, these results indicate that hemodialysis increases the incidence of PD. The differences in the characteristics between male hemodialysis patients with and without PD provide new insights into the pathophysiology and therapeutic window of PD.

ABSTRACT

Inclusion body disease (IBD) is an infectious fatal disease of snakes typified by behavioral abnormalities, wasting, and secondary infections. At a histopathological level, the disease is identified by the presence of large eosinophilic cytoplasmic inclusions in multiple tissues. To date, no virus or other pathogen has been definitively characterized or associated with the disease. Using a metagenomic approach to search for candidate etiologic agents in snakes with confirmed IBD, we identified and
de novo
assembled the complete genomic sequences of two viruses related to arenaviruses, and a third arenavirus-like sequence was discovered by screening an additional set of samples. A continuous boa constrictor cell line was established and used to propagate and isolate one of the viruses in culture. Viral nucleoprotein was localized and concentrated within large cytoplasmic inclusions in infected cells in culture and tissues from diseased snakes. In total, viral RNA was detected in 6/8 confirmed IBD cases and 0/18 controls. These viruses have a typical arenavirus genome organization but are highly divergent, belonging to a lineage separate from that of the Old and New World arenaviruses. Furthermore, these viruses encode envelope glycoproteins that are more similar to those of filoviruses than to those of other arenaviruses. These findings implicate these viruses as candidate etiologic agents of IBD. The presence of arenaviruses outside mammals reveals that these viruses infect an unexpectedly broad range of species and represent a new reservoir of potential human pathogens.

IMPORTANCE
Inclusion body disease (IBD) is a common infectious disease of captive snakes. IBD is fatal and can cause the loss of entire animal collections. The cause of the disease has remained elusive, and no treatment exists. In addition to being important to pet owners, veterinarians, breeders, zoological parks, and aquariums, the study of animal disease is significant since animals are the source of virtually every emerging infectious human disease. We searched for candidate causative agents in snakes diagnosed with IBD and found a group of novel viruses distantly related mainly to arenaviruses but also to filoviruses, both of which can cause fatal hemorrhagic fevers when transmitted from animals to humans. In addition to providing evidence that strongly suggests that these viruses cause snake IBD, this discovery reveals a new and unanticipated domain of virus biology and evolution.
