Influence of Socio-Economic Inequalities on Access to Renal Transplantation and Survival of Patients with End-Stage Renal Disease

BackgroundPublic and scientific concerns about the social gradient of end-stage renal disease and access to renal replacement therapies are increasing. This study investigated the influence of social inequalities on the (i) access to renal transplant waiting list, (ii) access to renal transplantation and (iii) patients’ survival.MethodsAll incident adult patients with end-stage renal disease who lived in Bretagne, a French region, and started dialysis during the 2004–2009 period were geocoded in census-blocks. To each census-block was assigned a level of neighborhood deprivation and a degree of urbanization. Cox proportional hazards models were used to identify factors associated with each study outcome.ResultsPatients living in neighborhoods with low level of deprivation had more chance to be placed on the waiting list and less risk of death (HR = 1.40 95%CI: [1.1–1.7]; HR = 0.82 95%CI: [0.7–0.98]), but this association did not remain after adjustment for the patients’ clinical features. The likelihood of receiving renal transplantation after being waitlisted was not associated with neighborhood deprivation in univariate and multivariate analyses.ConclusionsIn a mixed rural and urban French region, patients living in deprived or advantaged neighborhoods had the same chance to be placed on the waiting list and to undergo renal transplantation. They also showed the same mortality risk, when their clinical features were taken into account.     

A partnership project for a new Red List of the Italian Flora

Abstract

The IUCN Red Lists assessment provides an internationally accepted system to verify the extinction risk of species. Working Groups of the Italian Botanical Society have recently discussed the importance of producing a reliable list of species at the national level. This list could be the starting point for future in situ and ex situ plant conservation activities.     

Iodine Content in Meal Replacements in the United States

ObjectiveIodine is essential for thyroid hormone production. The recommended dietary allowance for iodine in nonpregnant adults is 150 μg/d. However, most product labels do not list the iodine content. Meal replacements are not required to contain specific vitamins and minerals. Nevertheless, they are often marketed as good and convenient sources of a balanced nutrition. In this study, we aimed to assess the iodine content in meal replacements to determine how they may contribute to iodine deficiency or excess.MethodsTwenty seven meal replacements from supermarkets in the Boston area were collected. The iodine concentration of each meal replacement was measured spectrophotometrically. Iodine content in meal replacements were compared according to form (liquid, bar, and powder) and type (vegan and nonvegan).ResultsThe overall mean ± SD iodine content was 49.7 ± 125.4 μg/serving. However, 1 meal replacement was an outlier and had 671.9 μg iodine per serving. Mean iodine content differed between forms and was highest for liquids (mean ± SD: 37.4 ± 6.5 μg/serving). Nonvegan meal replacements had a higher mean iodine content than vegan meal replacements (mean ± SD: 31.6 ± 15.78 μg/serving).ConclusionAll of the meal replacements contained detectible amounts of iodine regardless of whether it was listed on their labels (41% did not list iodine). Overall, the meal replacements in this study were found to be good sources of iodine. However, consumers should be aware that packaging labels may not accurately reflect the amount of iodine present.     

Diez recomendaciones para mejorar la enseñanza de la Geriatría en el pregrado

IntroductionPopulation ageing and scientific progress have made specific training in Geriatrics essential for any medical students. There are different international recommendations on the teaching of Geriatric Medicine at undergraduate level, but they are still far from being offered systematically. The aim of this work was to develop a National list of recommendations in order to improve training in Geriatric Medicine at the undergraduate level.Material and methodsA list of 10 recommendations was produced by reflecting on the Geriatric training situation in Spain in 2016/2017 and international recommendations. Consensus was reached among the members of the Spanish Society of Geriatrics and Gerontology (SEGG) working group on «Geriatric training at undergraduate level» through 2 meetings and online discussions.ResultsA list of 10 of recommendations on Geriatric training in Spanish Medical Schools is proposed, including areas such as, the status of the discipline in the curriculum, length, contents, practical training, lecturers, teaching methods, and innovation.ConclusionsThese recommendations are intended to improve Geriatrics training. They can be used by different Medical Schools either to adapt their programs or to start training in Geriatric Medicine.

Towards complete and accurate reporting of studies of diagnostic accuracy: the STARD initiative

ObjectiveTo improve the accuracy and completeness of reporting of studies of diagnostic accuracy, to allow readers to assess the potential for bias in a study, and to evaluate a study''s generalisability.MethodsThe Standards for Reporting of Diagnostic Accuracy (STARD) steering committee searched the literature to identify publications on the appropriate conduct and reporting of diagnostic studies and extracted potential items into an extensive list. Researchers, editors, and members of professional organisations shortened this list during a two day consensus meeting, with the goal of developing a checklist and a generic flow diagram for studies of diagnostic accuracy.ResultsThe search for published guidelines about diagnostic research yielded 33 previously published checklists, from which we extracted a list of 75 potential items. At the consensus meeting, participants shortened the list to a 25 item checklist, by using evidence, whenever available. A prototype of a flow diagram provides information about the method of patient recruitment, the order of test execution, and the numbers of patients undergoing the test under evaluation and the reference standard, or both.ConclusionsEvaluation of research depends on complete and accurate reporting. If medical journals adopt the STARD checklist and flow diagram, the quality of reporting of studies of diagnostic accuracy should improve to the advantage of clinicians, researchers, reviewers, journals, and the public.The Standards for Reporting of Diagnostic Accuracy (STARD) steering group aims to improve the accuracy and completeness of reporting of studies of diagnostic accuracy. The group describes and explains the development of a checklist and flow diagram for authors of reports     

A preliminary list of the Muscidae (Diptera) of the Magadan region,Russia

A preliminary list is given of the species of the Muscidae (Diptera) of the Magadan region, including 93 species in 23 genera. Eighty-one species are newly recorded from this territory. Six species [Spilogona aenea Huckett, 1965, S. bifimbriata Huckett, 1965, S. fulvibasis Huckett, 1965, S. incerta Huckett, 1965, S. separata Huckett, 1965, S. trigonifera (Zetterstedt, 1838)] are newly recorded for Russia. All these species, except Spilogona trigonifera, are newly recorded for the Palaearctic region. The species list includes the material examined, ecological data of some species, the distribution and all known references to each species. According to preliminary estimates, this list reflects 60% of expected species in the Magadan region. Two new synonyms are proposed: Coenosia shumshuensis Shinonaga & Zhang, 2000, n. syn. for C. alaskensis Huckett, 1965, and Coenosia remissa Huckett, 1965, n. syn. for C. ciliata Hennig 1961.

An assessment of red list data for the Pezizomycotina (Ascomycota): Umbria (Italy) as a test case

Abstract

A Red List of all 108 Pezizomycotina (Ascomycota) species recorded in Umbria Region (central Italy) is provided. According to the IUCN categories and criteria, 60.18% of the assessed species are classified as threatened, whereas 12.96% are Near Threatened (NT), 1.86% are Least Concerned (LC) and a noteworthy amount of 25% are Data Deficient (DD). As a consequence of the downlisting applied to the majority of the assessed taxa, according to the guidelines for application of IUCN red list criteria at Regional level, only 1.54% of the threatened species is Critically Endangered (CR), while 46.15% are Endangered (EN) and 52.31% are Vulnerable (VU). Given that the present work represents the first complete regional red list of Pezizomycotina in Italy, and that a national, as well as a European red list do not exist to date, it could be considered as a case study for other Italian Regions as well as for other European countries, aiming at the compilation of a national and European red list of this fungal group mostly overlooked in conservation strategies.     

Characterization of a dominant mutation for the liguleless trait: Aegilops tauschii liguleless (Lgt)

Background

Leaves of Poaceae have a unique morphological feature: they consist of a proximal sheath and a distal blade separated by a ligular region. The sheath provides structural support and protects young developing leaves, whereas the main function of the blade is photosynthesis. The auricles allow the blade to tilt back for optimal photosynthesis and determine the angle of a leaf, whereas the ligule protects the stem from the entry of water, microorganisms, and pests. Liguleless variants have an upright leaf blade that wraps around the culm. Research on liguleless mutants of maize and other cereals has led to identification of genes that are involved in leaf patterning and differentiation.

Results

We characterized an induced liguleless mutant (LM) of Aegilops tauschii Coss., a donor of genome D of bread wheat Triticum aestivum L.. The liguleless phenotype of LM is under dominant monogenic control (Lg^t). To determine precise position of Lg^t on the Ae. tauschii genetic map, highly saturated genetic maps were constructed containing 887 single-nucleotide polymorphism (SNP) markers derived via diversity arrays technology (DArT)seq. The Lg^t gene was mapped to chromosome 5DS. Taking into account coordinates of the SNP markers, flanking Lg^t, on the pseudomolecule 5D, a chromosomal region that contains this gene was determined, and a list of candidate genes was identified. Morphological features of the LM phenotype suggest that Lg^t participates in the control of leaf development, mainly, in leaf proximal–distal patterning, and its dominant mutation causes abnormal ligular region but does not affect reproductive development.

Conclusions

Here we report characterization of a liguleless Ae. tauschii mutant, whose phenotype is under control of a dominant mutation of Lg^t. The dominant mode of inheritance of the liguleless trait in a Triticeae species is reported for the first time. The position of the Lg^t locus on chromosome 5DS allowed us to identify a list of candidate genes. This list does not contain Ae. tauschii orthologs of any well-characterized cereal genes whose mutations cause liguleless phenotypes. Thus, the characterized Lg^t mutant represents a new model for further investigation of plant leaf patterning and differentiation.

Severe Hyponatre mia Due to Rosiglita zone Use in an Elderly Woman With Diabetes Mellitus: A Rare Cause of Syndrome of Inappropriate Antidiuretic Hormone Secretion

ObjectiveTo describe the first case of syndrome of inappropriate antidiuretic hormone secretion with lifethreatening hyponatremia due to rosiglitazone therapy.MethodsWe describe the clinical, laboratory, and imaging findings of the study patient.ResultsAn 89-year-old woman with a 5-year history of type 2 diabetes mellitus was admitted to the emergency department because of unconsciousness. She had reported generalized weakness for 15 days and nausea and vomiting for 3 days. Findings from laboratory analysis showed severe hyponatremia (sodium, 110 mEq/L). She had normal renal, cardiac, and adrenal function, and she did not have edema or volume depletion. The cause of hyponatremia was syndrome of inappropriate antidiuretic hormone secretion. We did not find any cause for her condition other than rosiglitazone, an antihyperglycemic drug that is increasingly being used in patients with type 2 diabetes mellitus. According to her medical history, rosiglitazone was prescribed 1 month previously after withdrawal of gliclazide. We stopped the rosiglitazone and administered hypertonic saline infusion to treat the hyponatremia. Saline infusion was stopped and blood sodium levels were stabilized in the normal range after 2 days. The patient’s plasma sodium concentration has remained in the reference range at follow-up visits.ConclusionsThis is the first reported case of syndrome of inappropriate antidiuretic hormone secretion as an adverse effect of rosiglitazone, and this drug should possibly be considered for addition to the list of drugs that cause this condition.
