Abstract

Kinetic studies of the acylation of neutral secondary phosphoramidates by acid halides and anhydrides are reported. The reactions produce both N-acylphosphoramidates and carboxamides by cleavage of the P–N bond. The extent of carboxamide formation varies with the stregth of the acid co-product and with steric and electronic factors associated with both the acylating agent and the nitrogen substituent of the phosphoramidate. Except for pivaloyl chloride, the presence of a base diminishes the amount of carboxamide formed. With either acid halides or anhydrides tertiary phosphoramidates produce carboxamides directly. The formation of both N-acylphosphormidate and carboxamide follow the equation: rate =k2[phosphoramidate][acid halide or anhydride]. Second-order rate constants, k2, for the formation of N-acylphosphoramidates vary with the structure of the acylating agent: AcBr is 18 times more reactive than AcCl; in solvent pyridine the Hammett ρ-value for substituted benzoyl chlorides is 1.8; in solvent CCl4 Taft ρ* and δ values for substituted acid chlorides are 0.7 and 0.76 respectively. These data are best interpreted in terms of a bimolecular substitution reaction involving nucleophilic attack by the phosphoramidate nitrogen atom at the carbonyl carbon of the acylating agent to form an N-acylphosphoramidate cation (5). Breakdown of this cation can give either the N-acylphosphoramidate via deprotonation, or the carboxamide via P–N bond cleavage. Carboxamide formation is favoured for reactions where P–N bond cleavage either relieves steric strain or the carboxamide is a good nucleofuge.Catalysis of the reaction between phosphoramidates and acetic anhydride by electrophiles such as AcX and HX is shown to involve acylation by AcX followed by a rapid re-formation of AcX from Ac2O and HX.

Abstract

Purpose: The Eastern Cooperative Oncology Group conducted a randomized phase II trial to determine the objective response rates, toxicities, and overall survival and to assess effects on quality of life for two combination regimens in patients with advanced gastric cancer.Patients and Methods: All patients had biopsy-proven, untreated metastatic gastric cancer with measurable disease. The FHIG arm employed infusional fluorouracil (F), 2.6 g/m2, given intravenously over 24 hours once perweek for 6 weeks; infusional hydroxyurea (H), 4.3 g/m2, given intravenously over 24 hours once per week for 6 weeks; and interferon-alpha-2a (1), 9 MU given subcutaneously three times per week, once per week for 6 weeks. The AD arm employed doxorubicin (A), 50 mg/m2, and docetaxel (D), 75 mg/m2, both given intravenously every 21 days. Quality of life was measured by the FACT-Fatigue scale and a novel questionnaire assessing interferon-mediated fatigue.Results: Twenty-nine patients were enrolled; 23 were eligible and evaluable. Twelve were enrolled on FHIG and 11 on AD. The major grade > or = 3 toxicities were neuromotor (46%) in patients receiving FHIG and granulocytopenia (91%) in those receiving AD. There were two fatalities in the AD arm. There was one partial responder on FHIG (8.3%) and none on AD. The median survival was 6.6 months for FHIG and 10.1 months for AD. Quality-of-life analysis did not show substantial cumulative fatigue in patients treated with FHIG.Conclusions: Neither regimen demonstrated enough activity to serve as a platform for the development of further clinical regimens against gastric carcinoma. A subset of patients receiving interferon was able to tolerate therapy without deterioration in quality of life. [ABSTRACT FROM AUTHOR]

Abstract

BackgroundMicroRNA (miRNA) regulation is associated with several diseases, including neurodegenerative diseases. Several approaches can be used for modeling miRNA regulation. However, their precision may be limited for analyzing multidimensional data. Here, we addressed this question by integrating shape analysis and feature selection into miRAMINT, a methodology that we used for analyzing multidimensional RNA-seq and proteomic data from a knock-in mouse model (Hdh mice) of Huntington’s disease (HD), a disease caused by CAG repeat expansion in huntingtin (htt). This dataset covers 6 CAG repeat alleles and 3 age points in the striatum and cortex of Hdh mice.ResultsRemarkably, compared to previous analyzes of this multidimensional dataset, the miRAMINT approach retained only 31 explanatory striatal miRNA-mRNA pairs that are precisely associated with the shape of CAG repeat dependence over time, among which 5 pairs with a strong change of target expression levels. Several of these pairs were previously associated with neuronal homeostasis or HD pathogenesis, or both. Such miRNA-mRNA pairs were not detected in cortex.ConclusionsThese data suggest that miRNA regulation has a limited global role in HD while providing accurately-selected miRNA-target pairs to study how the brain may compute molecular responses to HD over time. These data also provide a methodological framework for researchers to explore how shape analysis can enhance multidimensional data analytics in biology and disease.

Abstract

Background Several studies have suggested that vascular dysfunction plays an important role in Alzheimer’s disease. Aims We hypothesized that significant differences might be observed in the levels of blood endothelial biomarkers across elderly population of subjects with dementia. Methods We analyzed, in a prospective monocentric study, three different endothelial biomarkers, endothelial microparticles (EMPs), endothelial progenitor cells (EPCs) and circulating endothelial cells (CECs) in 132 older patients who underwent a full evaluation of a memory complaint. Results There was no difference in specific EMP, EPC or CEC levels between demented or non-demented patients, nor considering cognitive decline. Discussion Blood endothelial biomarkers may be too sensitive and it is likely that the multimorbidity observed in our patients may lead to opposite and confounding effects on endothelial biomarkers levels. Conclusion Unlike younger AD patients, our results suggest that endothelial biomarkers are not valuable for the diagnosis of dementia in elderly patients

Abstract

SATB2‐associated syndrome (SAS) is a rare disorder caused by alterations in the special AT‐rich sequence‐binding protein 2 (SATB2). Skeletal abnormalities such as tibial bowing, osteomalacia, osteopenia or osteoporosis have been reported suggesting a higher frequency of skeletal complications in SAS. The optimal timing, necessity, and methodology for routine assessment of bone health in individuals with SAS, however, remain unclear. We report molecular and phenotypic features of 7 individuals with SAS documented to have low bone mineral density (BMD) ascertained by dual‐energy X‐ray absorptiometry (DXA), often preceded by tibial bowing. The lowest BMD Z‐scores ranged −2.3 to −5.6. In 4 individuals, total alkaline phosphatase levels were elevated (2 with elevated bone fraction) around the time of low BMD documentation. A clinically significant fracture history and a diagnosis of pediatric osteoporosis were present in 4 individuals. Pamidronate treatment in 2 children improved BMD. In conclusion, low BMD, fractures, and tibial bowing are relatively common skeletal complications in individuals with SAS. DXA is a useful tool when evaluating a child with SAS suspected to have low BMD and the results might alter clinical management. [ABSTRACT FROM AUTHOR]

Abstract

We start by coupling negative 2-circuits, which are characteristic of the presence of a regulation loop in a dynamical system. This loop can be modelled with coupled differential equations represented in a first approach by a conservative differential system. Then, an example of regulation loop with a dissipative component will be given in human physiology by the vegetative system regulating the cardio-respiratory rhythms.

Abstract

The sugarcane borer, Diatraea saccharalis (F.), is one of the major target pests of transgenic maize, Zea mays , expressing Bacillus thuringiensis (Bt) proteins in South America and mid-southern region of the U.S. The MON89034 maize expresses Cry2Ab2 and Cry1A.105 Bt proteins and it was developed to provide better control of key lepidopteran pests of maize including D. saccharalis . The objectives of this study were to select and characterize the resistance of D. saccharalis to Cry2Ab2 using a non-commercial Cry2Ab2 single gene Bt maize line. A Cry2Ab2-resistant strain (Cry2Ab2-RR) of D. saccharalis was established from 28 two-parent families collected from fields in northeast Louisiana, U.S. The Cry2Ab2-RR showed a high level of resistance to Cry2Ab2 in both diet-incorporated and whole maize plant bioassays. The Cry2Ab2 resistance in D. saccharalis was likely inherited as a single or a few tightly linked autosomal genes. The resistance was non-recessive and not associated with fitness costs. The results should provide valuable information in resistance monitoring, assessing resistance risk, and developing effective management strategies for the sustainable use of Bt maize technology for managing maize stalk borers.

Abstract

Ungulates often adjust their diet when food availability varies over time. However, it is poorly understood when and to what extent individuals change their diet and, if they do so, if all individuals of a population occupy distinct or similar dietary niches. In the arid Namibian Kunene Region, we studied temporal variations of individual niches in grazing gemsbok ( Oryx gazella gazella) and predominantly browsing springbok ( Antidorcas marsupialis). We used variation in stable C and N isotope ratios of tail hair increments as proxies to estimate individual isotopic dietary niches and their temporal plasticity. Isotopic dietary niches of populations of the two species were mutually exclusive, but similar in breadth. Isotopic niche breadth of gemsbok was better explained by within-individual variation than by between-individual variation of stable isotope ratios, indicating that gemsbok individuals were facultative specialists in using isotopically distinct local food resources. In contrast, inter- and intra-individual variations contributed similarly to the isotopic niche breadth of the springbok population, suggesting a higher degree of individual isotopic segregation in a more generalist ungulate. In both species, between-individual variation was neither explained by changes in plant primary productivity, sex, geographical position nor by group size. Within species, individual dietary niches overlapped partially, suggesting that both populations included individuals with distinct isotopic dietary niches. Our study provides the first evidence for isotopic dietary niche segregation in individuals of two distinct desert ungulates. Similar, yet isotopically distinct dietary niches of individuals may facilitate partitioning of food resources and thus individual survival in desert ecosystems. [ABSTRACT FROM AUTHOR]

Abstract

This study presents strategies to render triple-negative breast cancers sensitive to CDK4/6 inhibitors., Inhibitors of cyclin-dependent kinases CDK4 and CDK6 have been approved for treatment of hormone receptor–positive breast cancers. In contrast, triple-negative breast cancers (TNBCs) are resistant to CDK4/6 inhibition. Here, we demonstrate that a subset of TNBC critically requires CDK4/6 for proliferation, and yet, these TNBC are resistant to CDK4/6 inhibition due to sequestration of CDK4/6 inhibitors into tumor cell lysosomes. This sequestration is caused by enhanced lysosomal biogenesis and increased lysosomal numbers in TNBC cells. We developed new CDK4/6 inhibitor compounds that evade the lysosomal sequestration and are efficacious against resistant TNBC. We also show that coadministration of lysosomotropic or lysosome-destabilizing compounds (an antibiotic azithromycin, an antidepressant siramesine, an antimalaria compound chloroquine) renders resistant tumor cells sensitive to currently used CDK4/6 inhibitors. Lastly, coinhibition of CDK2 arrested proliferation of CDK4/6 inhibitor-resistant cells. These observations may extend the use of CDK4/6 inhibitors to TNBCs that are refractory to current anti-CDK4/6 therapies.

Abstract

Background: In recent large paediatric cardiomyopathy population studies from North America and Australia, vitamin 0 deficiency was not identified as a cause of infant heart failure. However, rickets is resurgent in developed countries. Objective: To review the prevalence of this cardiomyopathy in paediatric cardiology units of southeast England and determine the prognosis. Methods and results: A retrospective review from 2000 to 2006 in southeast England. Sixteen infants (6 Indian subcontinent, 10 black ethnicity) were identified: median (range) age at presentation was 5.3 months (3 weeks- 8 months). All had been breast fed. Ten presented at the end of the British winter )February-May). Median shortening fraction was 10% )range 5-18%) and median left ventricular end diastolic dimension z score was 4.1 (range 3.1-7.0). Six had a cardiac arrest; three infants died. Eight were ventilated, two required mechanical circulatory support and 12 required intravenous inotropic support. Two were referred for cardiac transplantation. Median (range) of biochemical values on admission was: total calcium 1.5 (1.07-1.74) mmol/l; alkaline phosphatase 646 (340-1057) lU/I; 25-hydroxyvitamin D 18.5 (0-46) nmol/l (normal range >35) and parathyroid hormone 34.3 (8.9-102) pmol/l (normal range <6.1). The clinical markers and echocardiographic indices of all survivors have improved. The mean time from diagnosis to achieve normal fractional shortening was 12.4 months. Conclusions: Vitamin D deficiency and consequent hypocalcaemia are seen in association with severe and life-threatening infant heart failure. That no infant or mother was receiving the recommended vitamin supplementation highlights the need for adequate provision of vitamin D to ethnic minority populations. [ABSTRACT FROM AUTHOR]

Abstract

Background Various factors may have deleterious effects on bone health in patients with epidermolysis bullosa (EB). Objectives In a retrospective notes review, to assess bone mineralization in children with EB and to identify the relative contributions of nutrition, activity and disease severity to low bone mass. Methods Thirty-nine children with EB [32 recessive dystrophic EB (RDEB), four Dowling–Meara EB simplex (DMEBS) and three junctional EB (JEB)] had lumbar spine bone mass measured using dual X-ray absorptiometry (GE Lunar Prodigy; GE Healthcare, Chalfont St Giles, U.K.). Seventy-six healthy children were also studied. Weight and height were recorded and mobility was rated. Results Children with RDEB and JEB, but not those with DMEBS, had lower bone mineral density SD scores than controls; differences remained after adjusting for the smaller body size of the patients. Bone mass was best predicted by mobility rating. Conclusions Children with RDEB and JEB have low bone mass after adjusting for their smaller size, which may put them at risk for fragility fractures. Low bone mass was best predicted by the level of mobility, raising the hypothesis that improving activity or bone loading may be a potential preventive intervention in these children. However, as low bone mass may be multifactorial in these children, more detailed investigation of potential aetiological factors is required before interventions are planned. [ABSTRACT FROM AUTHOR]

Abstract

International audience; Following a review of the available assessment scales and current practices of evaluation of instrumental activities of daily living (IADL) in French memory centres by GREFON (Groupe de reflexion sur l'evaluation fonctionnelle; Working Group on Functional Assessment), the main aim of this position paper was to provide good clinical practice (GCP) guidelines for the assessment of IADL. Another aim was to highlight the need for innovative tools adapted to the present and future evolution of such activities in real life, including the use of new technologies, the need for earlier detection of IADL impairment during the diagnostic process of mild neurocognitive disorders, and greater sensitivity to IADL changes during follow-up to allow adaptation of clinical management and evaluation of the impact of therapeutic interventions.

Abstract

From 1984 to 1996, 31 consecutive children without sibling donors, aged 5–19 years (median 8) with acute lymphoblastic leukaemia (ALL) in second complete remission (CR), received unpurged autologous bone marrow transplantation (ABMT) after melphalan and single fraction total body irradiation (TBI). ABMT was performed using fresh unmanipulated marrow harvested after standard reinduction and consolidation therapy 2–11 months (median 5) after relapse. With a median survival of 2.9 years the probability of survival for all patients in continuing second CR was 45.1% (95% CI, 24%-62%) after 5 years. Regimen-related and non-leukaemia mortality was 7% (95% CI, 2%-26%). The longest time to second relapse from ABMT was 3.1 years. Pituitary and gonadal dysfunction requiring hormonal replacement therapy occurred in the majority of long-term survivors. Twelve patients developed cataracts. ABMT with melphalan/single fraction TBI has proved an effective anti-leukaemia treatment with low regimen-related mortality but significant long-term morbidity. The current approach of allogeneic BMT from an unrelated donor when no sibling donor is available, following conditioning with cyclophosphamide/ fractionated TBI has resulted in a reduced relapse rate and improved short-term overall survival in the treatment of relapsed childhood ALL. However, long-term results are awaited. Bone Marrow Transplantation (2000) 25, 599–603. [ABSTRACT FROM AUTHOR]

Abstract

International audience; The role of brain cell-type-specific functions and profiles in pathological and non-pathological contexts is still poorly defined. Such cell-type-specific gene expression profiles in solid, adult tissues would benefit from approaches that avoid cellular stress during isolation. Here, we developed such an approach and identified highly selective transcriptomic signatures in adult mouse striatal direct and indirect spiny projection neurons, astrocytes, and microglia. Integrating transcriptomic and epigenetic data, we obtained a comprehensive model for cell-type-specific regulation of gene expression in the mouse striatum. A cross-analysis with transcriptomic and epigenomic data generated from mouse and human Huntington’s disease (HD) brains shows that opposite epigenetic mechanisms govern the transcriptional regulation of striatal neurons and glial cells and may contribute to pathogenic and compensatory mechanisms. Overall, these data validate this less stressful method for the investigation of cellular specificity in the adult mouse brain and demonstrate the potential of integrative studies using multiple databases.

Abstract

The last decade has seen a sharp increase in the number of scientific publications describing physiological and pathological functions of extracellular vesicles (EVs), a collective term covering various subtypes of cell-released, membranous structures, called exosomes, microvesicles, microparticles, ectosomes, oncosomes, apoptotic bodies, and many other names. However, specific issues arise when working with these entities, whose size and amount often make them difficult to obtain as relatively pure preparations, and to characterize properly. The International Society for Extracellular Vesicles (ISEV) proposed Minimal Information for Studies of Extracellular Vesicles ("MISEV") guidelines for the field in 2014. We now update these "MISEV2014" guidelines based on evolution of the collective knowledge in the last four years. An important point to consider is that ascribing a specific function to EVs in general, or to subtypes of EVs, requires reporting of specific information beyond mere description of function in a crude, potentially contaminated, and heterogeneous preparation. For example, claims that exosomes are endowed with exquisite and specific activities remain difficult to support experimentally, given our still limited knowledge of their specific molecular machineries of biogenesis and release, as compared with other biophysically similar EVs. The MISEV2018 guidelines include tables and outlines of suggested protocols and steps to follow to document specific EV-associated functional activities. Finally, a checklist is provided with summaries of key points.

Abstract

International audience; The aim of our study was to analyze polymorphonuclear neutrophil (PMN) functions in elderly individuals compared with those in healthy young participants, directly in whole blood to avoid issues with data interpretation related to cell isolation procedures. Despite the presence of increased circulating levels of proinflammatory cytokines, resting PMNs from the elderly individuals were not activated as shown by normal CD62L and CD11b expression at the PMN surface and normal constitutive reactive oxygen species (ROS) production. However, suboptimal stimulation induced modulations of CD62L and CD11b expression, which positively correlated with the interleukin-6 circulating level, suggesting a possible in vivo preactivation of old PMNs by this cytokine. In addition, PMN phagocytosis of opsonized Escherichia Coli was decreased in elderly individuals. Furthermore, upon preincubation of elderly whole-blood samples with tumor necrosis factor-a or Toll Receptor agonists, we observed a reduced PMN oxidative burst in response to formyl peptides. Elderly participants also exhibited an increased percentage of the immunosuppressive CD16(bright)/CD62L(dim) PMN subpopulation, which was characterized by a lower phagocytic index and a reduced ROS production compared with the CD16(bright)/CD62L(bright) subset. Thus, the reduced phagocytosis and ROS production associated with an expansion of immunosuppressive CD16(bright)/CD62L(dim) PMN subpopulation might be involved in the increased susceptibility to bacterial and fungal infections with old age.

Abstract

International audience; Background: Orthopedic surgery is more and more frequent in the older patients and is associated with a high mortality rate. Although serum procalcitonin levels are associated with prognosis in young adults, data are still lacking in the elderly population, and especially after surgery. The main objective of this study was to determine the prognostic value of procalcitonin levels in a large geriatric orthopedic population, and we compared it with clinical variables and biomarkers. Methods: This is a prospective study including patients admitted in our dedicated geriatric postoperative unit, after orthopedic surgery with immediate postoperative measured procalcitonin levels. Collected data included age, sex, medical history, functional status (activities of daily living [ADL]), fracture type, Cumulative Illness Rating scale (CIRS), postoperative complications, and biological data. The primary endpoint was the 30-day mortality. Results: 436 patients (age 85 +/- 6 years) were included. Hip fracture surgery was the most frequent (n = 310; 71%), and the 30-day mortality rate was 6.9%. Compared with C-reactive protein (CRP), albumin, CIRS, and ADL, procalcitonin had the highest area under the receiver operating characteristic curve for predicting 30-day mortality (0.74; 95% CI: 0.70-0.78). Using a cutoff at 1 mu g/L, procalcitonin was more specific than CIRS to predict 30-day mortality (92 vs 77%; p

Abstract

Adult neurons from Caenorhabditis elegans can extrude large membrane-surrounded vesicles, known as exophers, containing protein aggregates and dysfunctional organelles that threaten neuronal homeostasis. Monica Driscoll and colleagues show that in the nematode Caenorhabditis elegans, adult neurons are able to extrude large membrane-surrounded vesicles, dubbed exophers, that may contain protein aggregates and organelles. Inhibiting chaperone expression, autophagy or the proteasome, or compromising mitochondrial quality, results in increased exopher production. Proteotoxically stressed neurons that extrude exophers subsequently function better than similarly stressed neurons that do not. These data suggest that exopher-genesis is a potential cellular 'garbage-removal' response. The toxicity of misfolded proteins and mitochondrial dysfunction are pivotal factors that promote age-associated functional neuronal decline and neurodegenerative disease1,2. Accordingly, neurons invest considerable cellular resources in chaperones, protein degradation, autophagy and mitophagy to maintain proteostasis and mitochondrial quality3,4. Complicating the challenges of neuroprotection, misfolded human disease proteins and mitochondria can move into neighbouring cells via unknown mechanisms, which may promote pathological spread5,6. Here we show that adult neurons from Caenorhabditis elegans extrude large (approximately 4 μm) membrane-surrounded vesicles called exophers that can contain protein aggregates and organelles. Inhibition of chaperone expression, autophagy or the proteasome, in addition to compromising mitochondrial quality, enhances the production of exophers. Proteotoxically stressed neurons that generate exophers subsequently function better than similarly stressed neurons that did not produce exophers. The extruded exopher transits through surrounding tissue in which some contents appear degraded, but some non-degradable materials can subsequently be found in more remote cells, suggesting secondary release. Our observations suggest that exopher-genesis is a potential response to rid cells of neurotoxic components when proteostasis and organelle function are challenged. We propose that exophers are components of a conserved mechanism that constitutes a fundamental, but formerly unrecognized, branch of neuronal proteostasis and mitochondrial quality control, which, when dysfunctional or diminished with age, might actively contribute to pathogenesis in human neurodegenerative disease and brain ageing.

Abstract

Background Elderly people are at risk of repeated hospitalizations, some of which may be drug related and preventable. In 2011, a group of French healthcare experts selected 5 iatrogenic alerts (IAs), based on criteria identified in a literature search and from their professional experience, to assess the appropriateness of medication in elderly patients. Objectives Our objective was to examine the association between hospitalizations and IAs in elderly patients treated for Alzheimer disease who are particularly sensitive to adverse drug events. Design A 2-year (January 1, 2011, to December 31, 2012) longitudinal national database study, with a study design similar to self-controlled case series, was performed to analyze data on drug prescriptions and hospitalization. IAs were defined as (1) long half-life benzodiazepine; (2) antipsychotic drugs in patients with Alzheimer disease; (3) co-prescription of 3 or more psychotropic drugs; (4) co-prescription of 2 or more diuretics; and (5) co-prescription of 4 or more antihypertensive drugs. Data were obtained by matching of 2 French National Health Insurance Databases. Setting France. Participants All affiliates, aged ≥75 years, receiving treatment for Alzheimer disease, alive on January 1, 2011 were included. Measurements We calculated the relative increase in the number of hospitalizations in patients with IAs. The analysis was performed over four 6-month periods. Results A total of 10,754 patients were included. During the periods with IAs, hospitalization rates increased by 0.36/year compared with 0.23/year in the periods without for the same patient, and the number of hospitalizations doubled [proportional fold change = 1.9, 95% confidence interval (1.8, 2.1)]. We estimated that 22% [95% confidence interval (20%, 23%)] of all hospitalizations were associated with IAs, 80% of which were due to psychotropic IAs. Conclusions The IAs could be used as a simple and clinically relevant tool by prescribing physicians to assess the appropriateness of the prescription in elderly patients treated for Alzheimer disease.

Abstract

International audience; Abstract: Background: Dementia is associated with a worse prognosis of hip fracture, but the impact of a dedicated geriatric care pathway on the prognosis of these patients has not been evaluated. Objective: According to the cognitive status before surgery, our main objective was to compare mortality rate at 6 months; secondary outcomes were to compare in-hospital complications, the risk of new institutionalization, and the ability to walk at 6 months. Methods: Between 2009 and 2015, all patients (>70 years) admitted after hip fracture surgery into a dedicated unit of peri-operative geriatric care were included: patients with dementia (DP), without dementia (NDP), and with cognitive status not determined (CSND). Data are expressed as hazard ratio (HR) for multivariate cox analysis or odds ratio (OR) for multivariate logistic regression analysis and their 95% confidence interval (CI). Results: We included 650 patients (86±6 years): 168 DP, 400 NDP, and 82 CSND. After adjustment for age, sex, comorbidities, polypharmacy, pre-fracture autonomy, time-to-surgery, and delirium, there were no significant differences for 6-month mortality (DP versus NDP: HR = 0.7[0.4–1.2], DP versus CSND: HR = 0.6[0.3–1.4], CSND versus NDP: HR = 0.8[0.4–1.7]); but DP and CSND were more likely to be newly institutionalized after 6 months compared to NDP (OR DP = 2.6[1.4–4.9], p = 0.003, OR CSND = 2.9[1.4–6.1], p = 0.004). 92% of population was walking after 6 months (63% with assistance): no difference was found between the three groups. Conclusion: In a dedicated geriatric care pathway, DP and CSND undergoing hip surgery have the same 6-month mortality and walking ability as NDP.

Abstract

Ungulates are famous for large-scale movements in response to local and regional changes in plant productivity. However, it is poorly understood how non-migratory ungulates respond towards shortages in plant availability. In the arid Kunene Region of Namibia, we studied the variation of home ranges and habitat use of gemsbok during a period of severe drought that led to a critical food shortage. We then related the spatiotemporal behaviour of gemsbok to relative plant greenness and local plant productivity, using local Normalized Differenced Vegetation Indices (NDVI) as a proxy, and to satellite images to assess habitat types and topography. Core home range sizes of gemsbok did not vary with decreasing local NDVI values, while total home-ranges increased with decreasing NDVI values. Gemsbok responded to resource fluctuations by using a combination of habitats differing in plant productivity, topography and vegetation cover. Gemsbok increased the number of habitats used when NDVI values decreased. Individuals remained non-migratory even during the period of peak drought. Non-migratory gemsboks are capable of exploiting local resources efficiently by adjusting their habitat use, when facing declining resources and unpredictable food shortages. Our study provides important information on the habitat use of gemsbok for the sustainable management of populations in arid environments. • Desert-dwelling gemsbok selected their resource habitats as aridity and associated environmental uncertainties increased. • Gemsbok use a combination of different interlacing habitats allowing them to survive in even extreme desert environments. • Higher NDVI values did not fully explain the movement behaviour and habitat selection of Gemsbok. • Inter-individual variation in home range and habitat use reflect dietary preferences of gemsbok. • Conserving corridors between core refuge habitats may support the sustainable management of ungulate populations.

Abstract

International audience; Pembrolizumab is an immune checkpoint blockade (ICB) monoclonal antibody. ICBs have been associated with a number of adverse effects including rhabdomyolysis and increased CPK levels. Here, we describe a pembrolizumab-induced necrotic myositis in a patient treated for melanoma. Prompt recognition may improve the clinical and functional outcome of patients.
