OBJECTIVE
This study was conducted to investigate the association of diabetic peripheral neuropathy (DPN) with both arterial stiffness and intima–media thickness (IMT).

RESEARCH DESIGN AND METHODS
We conducted a cross-sectional analysis of 731 subjects with type 2 diabetes. DPN was diagnosed on the basis of neuropathic symptoms, insensitivity to a 10-g monofilament, abnormal pin-prick sensation, and abnormal current perception threshold. Arterial stiffness was assessed by cardio-ankle vascular index (CAVI), and IMT was assessed by B-mode ultrasonography.

RESULTS
Patients with DPN had higher CAVI than those without DPN in multivariate-adjusted models, whereas no differences in IMT were observed between patients with and without DPN after adjustment for age and sex. In the multivariate analysis, CAVI was a significant determinant of DPN (odds ratio 1.36 [95% CI 1.13–1.65], P = 0.001).

CONCLUSIONS
DPN is significantly associated with arterial stiffness without carotid intimal changes in patients with type 2 diabetes.
Idéal féministe et injonction à l'autonomie économique. Le travail social des associations luttant contre les violences conjugales
Authors: Herman Elisa 
Published: April 2011

Résumé Les associations luttant contre les violences sont prises dans une ambivalence : malgré l’idéal féministe de l’émancipation et de la prise de conscience des rapports de force hiérarchisés, la « réinsertion » par l’économie prévaut. Sous la pression de leurs financeurs demandant une « rotation » des personnes hébergées, les travailleuses sociales sont contraintes de céder aux sirènes de l’autonomie économique, amenant les femmes hébergées à chercher un emploi parmi les plus précarisés et les plus pénibles. Celles-ci étant souvent seules avec leurs enfants, elles doivent trouver un mode de garde et ainsi alimenter la chaîne de la délégation marchande du travail de care . C’est alors que se trouve renforcée la division sexuelle du travail professionnel et domestique, malgré l’ambition féministe d’un changement social, quand le travail social ne peut apporter qu’une aide individualisée sans maîtriser l’ensemble des rouages dans lesquels il est pris.
THE LEPIDOPTERA OF BERMUDA: THEIR FOOD PLANTS, BIOGEOGRAPHY, AND MEANS OF DISPERSAL
Authors: Ferguson D.C. , Hilburn D.J. , Wright B. 
Published: April 2011

AbstractThe 183 species of Lepidoptera recorded from Bermuda are discussed with respect to their world distribution, origin, long-range dispersal capability, host plants, nomenclature, and the circumstances of their occurrence in Bermuda; most are illustrated. Fifty-nine species are reported from Bermuda for the first time; Oenobotys invinacealis Ferguson (Pyralidae) and Tetanolita mynesalis inaequalis Ferguson (Noctuidae) are described as new. Four new genus–species combinations and four new synonymies are proposed.The Bermuda islands have a distressed fauna dominated by introduced pest species and migrants from the North American mainland and Caribbean Region. About 125 of the 183 recorded species are thought to be established residents; the remainder are assumed to be vagrants. Of approximately 50 resident species identified as probably indigenous, 11 species and three subspecies are endemic, and one of these, Semiothisa ochrifascia (Warren), is believed extinct.All Bermudian Lepidoptera are of American origin except the few introduced Old World species that are nearly cosmopolitan. Like Norfolk Island, Australia, Bermuda has a supersaturated lepidopterous fauna — more recorded species than its land area might support, which can be explained only by a high incidence of migrants and transients. This migratory component is explained relative to long-range movements of the same or congeneric species elsewhere; and hypotheses are proposed concerning the natural history of long-range dispersal in eastern North America and the ability of these moths to reach Bermuda. From a list of 113 species of Lepidoptera identified as frequent south–north migrants on the mainland, 76 are recorded from Bermuda. These include 38 of the 40 best-known cutworm moths of the eastern United States. It is argued that such moths reach Bermuda repeatedly without man's assistance and must regularly travel similar distances in North America.
GENERIC REVISION OF PHORIDAE OF THE NEARCTIC REGION AND PHYLOGENETIC CLASSIFICATION OF PHORIDAE, SCIADOCERIDAE, AND IRONOMYIIDAE (DIPTERA: PHORIDEA)
Authors: Brown Brian V. 
Published: April 2011

AbstractThe Nearctic Region genera of Phoridae are revised, and it is shown that the current classification into three subfamilies is inadequate. The hypothesis that the most closely related taxa to the Phoridae are the Sciadoceridae and Ironomyiidae is supported. Use of these outgroups to polarize character states in the Phoridae allows the reorganization of this family into five subfamilies: Hypocerinae, Phorinae, Aenigmatiinae, Conicerinae, and Metopininae. The newly re-defined Phorinae is the adelphotaxon (sister-group) of the Aenigmatiinae + Conicerinae + Metopininae, among which the relationships are unresolved. The hypocerines are the adelphotaxon of all other extant Phoridae. Within the Hypocerinae the relationships of the 15 included world genera are hypothesized, and three new genera are proposed. The relationships of the eight world phorine genera are only partly resolved. The Aenigmatiinae is organized into two tribes: Aenigmatiini and Diplonevrini. The relationships of the seven world genera of Diplonevrini are hypothesized, whereas those of the Aenigmatiini are not discussed. The six world conicerine genera are revised and their relationships hypothesized. In the Metopininae, two major groups are recognized, theMetopina-group and theMegaselia-group.BeckerinaMalloch is the adelphotaxon of these two groups, whereasRhopicaSchmitz andTriphlebaRondani are successive outgroups of all metopinines. TheMetopina-group is mostly tropical in distribution and is not discussed further. TheMegaselia-group is partially organized into theGymnophora-subgroup and theApocephalus-subgroup. Species-level revisions of genera are needed before further progress can be made in this family, because the distribution of character states is insufficiently known. Genera in great need of revision includePeromitraEnderlein,ChaetopleurophoraSchmitz,MegaseliaRondani, andApocephalusCoquillett.
Comparison of different phosphorus extraction and determination methods using manured soils

Published: April 2011

Soil test P (STP) methods were developed for fertilizer P recommendation in crop production. As soil P content of arable land increases due to manure application, the suitability of these STP methods for assessing P runoff potential from a field needs to be evaluated. The objective of this research was to evaluate various P extraction and determination methods using manured soils for their potential use as environmental P testing methods. Eighty one soil samples were taken in 1998 from various manured fields and research plots across Alberta. Phosphorus in the samples was extracted using deionized water, Miller-Axley (0.03 M NH4F + 0.015 M H2SO4), modified Kelowna (0.015 M NH4F + 0.25 M NH4OAc), and Mehlich 3 (M3) (1.5 M NH4F + 0.1 M EDTA) procedures. Phosphorus concentration in all extraction solutions was determined by the molybdenum blue colorimetric method in a Technicon II autoanalyzer. In addition, P content of the deionized water and M3 extractions was determined by an inductively coupled plasma emission spectroscopy (ICP) method. Soluble organic carbon content was measured in the deionized water extraction. The extractable P concentration increased as the acidity of the extraction solution increased in the order: M3 > modified Kelowna > Miller-Alxey > deionized water. The P extracted by Miller-Axley and M3 was strongly related to the deionized water extractable P, suggesting that both methods may be useful in assessing potential P runoff from arable land. The P concentration by the ICP determination was much higher than with the colorimetric method in M3 and the deionized water. The P concentration difference between the two determination methods was largely correlated to the soluble organic carbon in the deionized water extraction (r = 0.828***), suggesting that the undetected P by the molybdenum blue colorimetric method may exist in organic forms. To asses P runoff risk from arable land, both soluble inorganic and organic P need to be considered, and the ICP method can determine the total P, which includes both. In developing a STP for environmental soil P management, both P extraction and P determination methods should be standardized, and our results suggest that M3 and Miller-Axley extraction, and ICP determination are suitable methods for assessing P runoff.

Increase in phosphorus concentration of a clay loam surface soil receiving repeated annual feedlot cattle manure applications in southern Alberta
Authors: Joann K. Whalen Chi Chang, , Hao Xiying 
Published: April 2011

Migration of P from soils to water resources poses a risk of surface water eutrophication, and increase in P concentration in soils through manure or fertilizer addition would exace rbate this problem. Investigating the rate of increase in P concentration of surface soil receiving livestock manure is crucial to the development of best manure management strategies and prevention of eutrophication of aquatic systems. In this study, the changes in P concentrations of surface soils (0- to 15-cm depth) receiving 25 annual manure applications at rates of 0, 30, 60 and 90 Mg ha-1 yr-1 under non-irrigated conditions and at rates of 0, 60, 120 and 180 Mg ha-1 yr-1 under irrigated conditions were examined. The soil test P (STP) and total P (TP) of the surface soil increased with the TP through manure application over a 25-yr period. The STP pool was about 38% of the soil TP pool, similar to ratios of STP to TP in feedlot cattle manure. While the high proportion of STP to TP could be beneficial for crop production, it could also increase the potential for P losses from these soils through runoff and leaching. The changes in TP and STP concentrations of the surface soil were modelled with an expone ntial rise to maximum function: TP = 0.69 + 5.06 (1 − e(−0.087x)) and STP = 0.029 + 2.21 (1 − e(−0.082x)) where x is the cumulative TP applied. Although the model was developed for a specific soil and type of manure, it could be adapted to other soils or manure sources by adjusting the model coefficients for the particular soil and/or manure type. These adjustments would not require as extensive a data set as was required to develop the original model. This model could be used to determine the amount of TP that could be applied for a given critical STP. Producers, regulatory agencies, planners, and extension specialists could also use this model to make decisions on manure P management.

Influence of aggregate architecture and minerals on living habitats and soil organic matter
Authors: Monreal C. M. , Kodama H. 
Published: April 2011

We used an integrated approach to determine the effects of soil particle architecture and minerals on living habitats and soil organic matter (SOM). Macroaggregate (> 250 µm), microaggregate 1 (50–250 µm), and microaggregate 2 (< 50 µm) fractions of adjacent forested and cultivated Gleysolic soil were obtained by wet sieving. The forested site was used as a reference to evaluate the effects of cultivation on soil particle architecture. Aggregates and respective clay fractions were characterized using optical, chemical, physical and microbial methods. Microaggregates 1 had primary particles with the largest mean equivalent spherical diameter (ESD) and void volume of all aggregate fractions. These physical characteristics were paralleled by the highest SOM and microbial biomass content, and number of microorganisms. Cultivation increased the weathering of primary particles and SOM loss, and decreased the content of microbial pools, suggesting deteriorated living habitats. Soil organic C content in aggregates correlated significantly with the amount of ammonium oxalate extractable Al, chloritized vermiculite, and vermiculite, and was inversely associated with the total clay content. The mean ESD of primary particles and expandable phyllosilicates of aggregates influenced living habitats by supplying substrates, and providing different void and protective space for soil microorganisms.

Slope position and subsoiling effects on soil water and spring wheat yield
Authors: McConkey B. G. , Ulrich D. J. , Dyck F. B. 
Published: April 2011

A study was conducted on a 4-m-high ridge in southwestern Saskatchewan to determine the relationship of slope position with the soil water regime and spring wheat (Triticumaestivum L.) production and to determine if those relationships were altered by subsoiling. In all years, available soil water in the spring to 120 cm increased significantly with distance upslope. This pattern was attributed to residual subsoil water in the rooting zone that had not been used by previous crops in a long-term crop-fallow rotation. After 3 yr of annual spring wheat production, soil water to 1.2 m at all slope positions approximately equalled the water content wilting point (4.0 MPa) water content, showing this residual water had been largely consumed. Apparent use of soil water between seeding and harvest at the upper slope positions was equal to or greater than that at the lower slope positions. Over-winter soil water conservation, using tall (≥ 30-cm-high) wheat stubble for snow trapping, at the upper slope positions was equal to or greater than that at the lower slope positions. In the non-drought years of 1987 and 1989, wheat yields and crop water use efficiency increased significantly with distance downslope. Since these slope effects were not related to water use or availability, they were attributed to higher soil productivity, probably related to more historical net erosion with distance upslope. During the drought year of 1988, wheat yields and water use efficiency were greatest at the upslope positions, but these results were confounded by uneven crop emergence. Subsoiling to 35 cm or deeper increased the amount and depth of infiltration of water in years with near-average November–April precipitation. Subsoiling had little effect on wheat yields and no effect on crop water use. Key words: Landscape, wheat, productivity, soil moisture

The main objective of this study was to compare the recovery of 15N-labelled fertilizer by different methods of N application and N rates. Field experiments were carried out for 3 yr at Saint-Hyacinthe (Saint-Damase, Du Contour, Sainte-Rosalie soils) and at Saint-Lambert, Lévis (Le Bras soil). Grain corn (cv. Pride K228, 2700 CHU) and silage corn (cv. Hyland 3251, 2300 CHU) were grown at Saint-Hyacinthe and Saint-Lambert, respectively. In 1988 and 1989, field trials were arranged in a randomized complete bloc design consisting of five treatments in three replications: control 0 N and four split application methods of N fertilizer. Labelled 15NH4 15NO3 fertilizer was applied either banded at planting as starter (D), broadcast and incorporated before planting (Vs) or sidedressing between rows at V6 to V8 stages of corn (Bp). In 1990 field trials, treatments consisted of four N rates (0, 60, 120 and 180 kg N ha−1) labelled with 15NH4 15NO3. The effect of N rates on yield and N uptake by corn was significant in all years. However, the effect of application methods was significant only on the soil Du Contour in 1989 where corn grain yield was highest when N fertilizer was split as starter and sidedress band. The CUR of N fertilizer applied broadcast before planting (42 to 48%) was generally lower than sidedressing band application (43 to 54%). N fertilizer recovery in the starter showed also high CUR values (45 to 60%). Consequently, it is recommended to split N fertilizers and apply in band to increase efficiency for grain corn. The CUR values decreased with N rates only in Le Bras soil in 1990. Residual N fertilizer increased from 27 to 103 kg N ha−1 for 60 and 180 kg N ha−1 rates, respectively. Consequently, the environmental impact of N fertilization may increased with high N rate. Key words: Grain corn, silage corn, 15N recovery, fertilizer N split application
Nitrogen mineralization and availability in manure composts from Québec biological farms
Authors: N'Dayegamiye Adrien , Royer Raynald , Audesse Pierre 
Published: April 2011

The real contribution of composts to N availability depends on their characteristics and maturity. A laboratory incubation experiment (140 d) was conducted parallel to a greenhouse study (330 d) in a split-split-plot design, with, respectively, two peat rates (0, 20 gkg−1 soil), five manure composts and four compost rates (0, 250, 500 and 750 gkg−1 soil). Compost N mineralization, orchardgrass (Dactylis Glomerata L.) yield and N uptake were measured. Total amount of mineralized N and yields and N uptake for six cuts of orchardgrass varied significantly with the type of composts and rate. Peat addition temporarily decreased compost N mineralization rate but significantly increased orchardgrass yields and N uptake as compared to peatless treatments. Mineralized N represented <3% of total N, whereas N uptake by orchardgrass represented 13–40% of total N among composts. This low mineralized N value compared to total N and total N uptake was due to a high maturity of the composts studied. This was shown by high humic acid: fulvic acid fraction ratios (3.1 to 4.8) and low nonhumic fraction:humic acid+fulvic acid ratios (0.10 to 0.12), as well as low C/N ratios, high bulk density, high ash content, pH, NO3-N and CEC values. Even if peat addition decreased mineralized N basically due to temporary N immobilization, its application significantly increased yields and N uptake probably by improving physical conditions in soil-manure compost mixtures. Peat addition to mature manure composts should be considered as an interesting alternative for horticultural plants sensitive to high NO3-N content from mature composts.

Acidification rate of limed soil in a semiarid environment
Authors: Curtin D. , Ukrainetz H. 
Published: April 2011

To evaluate the benefits of liming acid soils, a method is needed to predict the longevity of its effect on soil pH. We coupled a simple index of soil buffering with estimates of the proton budget to predict long-term pH changes in a limed soil (Dark Brown Chernozem) in Saskatchewan. Analysis of published data for Saskatchewan soils showed that acceptable estimates of soil buffering can be obtained from organic matter and clay content. Buffer capacities of organic matter and clay were estimated at 487 and 26 mmol(±) kg−1 (pH unit)−1, respectively. Soil pH, titratable acidity, and effective cation exchange capacity (CEC) were monitored for 18 yr after lime application [Ca(OH)2 at rates of 0, 4.5 and 6.7 t ha−1] to field plots in a wheat (Triticum aestivum L.)-fallow rotation. In limed plots, there was a tendency for pH, exchangeable Ca and effective CEC to decrease with time in the 0–7.5 cm layer and to increase in the 7.5–15 cm layer. This was attributed to mixing of the two layers during cultivation. In the 0–15 cm layer as a whole, there was no discernible change in acidity, Ca, or CEC during the monitoring period. Negligible re-acidification in limed soil was consistent with the estimated H+ budget. External acidification sources were negligible (no N fertilizer was applied). Acidification due to leaching of nitrate and export of cations in grain over 18 yr was estimated at 6–7 kmol(H+) ha−1. This amount of acidity would lower soil pH by less than 0.1 units [buffer capacity of the top 15 cm of soil was ≈70 kmol(±) ha−1 (pH unit)–1], an amount too small to be detectable against background variability.

Published: May 2024

ImportancePremenstrual disorders (PMDs) adversely affect the quality of life of millions of women worldwide, yet research on the long-term consequences of PMDs is limited, and the risk of mortality has not been explored.ObjectiveTo estimate the associations of PMDs with overall and cause-specific mortality.Design, Setting, and ParticipantsThis nationwide, population-based, matched cohort study used data from population and health registers in Sweden. Participants included women of reproductive age with a first diagnosis of PMDs between January 1, 2001, and December 31, 2018. Data analysis was performed from September 2022 to April 2023.ExposuresPMDs were identified through inpatient and outpatient diagnoses and drug dispensing.Main Outcomes and MeasuresDates of death and underlying causes were ascertained from the National Cause of Death Register. Conditional Cox regression was used to estimate the hazard ratios (HRs) of overall and cause-specific death (eg, death due to natural or nonnatural cause, suicide, or cardiovascular events), adjusting for age, socioeconomic status, and somatic and psychiatric comorbidities; in a separate sibling comparison, models were also adjusted for all factors that sisters share.ResultsA total of 67 748 women with clinically diagnosed PMDs and 338 740 matched unaffected women were included, for a total of 406 488 women. Women with PMDs received a diagnosis at a mean (SD) age of 35.8 (8.2) years. During a mean (SD) follow-up of 6.2 (4.6) years (range, 1-18 years), 367 deaths were observed among women with PMDs (rate, 8.4 deaths per 10 000 person-years; 95% CI, 7.6-9.3 deaths per 10 000 person-years), and 1958 deaths were observed among women without PMDs (rate, 9.1 deaths per 10 000 person-years; 95% CI, 8.7-9.6 deaths per 10 000 person-years). Compared with unaffected women, women with PMDs had increased risk of death due to nonnatural causes (HR, 1.59; 95% CI, 1.25-2.04), particularly suicide (HR, 1.92; 95% CI, 1.43-2.60), but they did not have increased risk of overall mortality (adjusted HR, 0.91; 95% CI, 0.82-1.02). Notably, women who received a diagnosis before the age of 25 years experienced higher all-cause mortality (HR, 2.51; 95% CI, 1.42-4.42) and death from both suicide (HR, 3.84; 95% CI, 1.18-12.45) and natural causes (HR, 2.59; 95% CI, 1.21-5.54).Conclusions and RelevanceThe findings of this matched cohort study suggest that women with PMDs are not at increased risk of early death overall. However, the risk was elevated among young women and for death by suicide. This supports the importance of careful follow-up for young patients and highlights the need to develop suicide prevention strategies for all women with PMDs.
