Burden and Needs of Patients with Severe GvHD from the Supportive and Palliative Care Perspective—A Literature Review

Graft-versus-host disease (GvHD) is a frequent, and often life-threatening, complication after an allogeneic, hematopoietic stem cell transplantation (allo-SCT). It can appear in an acute or a chronic form and presents different grades of severity. Particularly, the severe forms of GvHD are often responsible for a change of the curative intent for allo-SCT into a palliative goal of care. For this non-systematic review, we conducted a focused literature search in the MEDLINE database via PubMed to examine whether patients with severe forms of GvHD might have special needs and burdens from a supportive and palliative care perspective. To draw a comprehensive picture of this patient group, we included findings on quality of life (QoL) and physical symptoms and function as well as psychological and spiritual well-being. In most domains, patients with severe forms of GvHD showed greater impairment and a higher symptom burden compared to patients with milder forms of GvHD. However, we could not identify any studies that specifically investigated patients with severe forms of GvHD. Further research in this field is necessary to guarantee the highest standard of care for this very special patient group

Do guidelines influence breathlessness management in advanced lung diseases? A multinational survey of respiratory medicine and palliative care physicians

Background: Respiratory medicine (RM) and palliative care (PC) physicians’ management of chronic breathlessness in advanced chronic obstructive pulmonary disease (COPD), fibrotic interstitial lung disease (fILD) and lung cancer (LC), and the influence of practice guidelines was explored via an online survey. Methods: A voluntary, online survey was distributed to RM and PC physicians via society newsletter mailing lists. Results: 450 evaluable questionnaires (348 (77%) RM and 102 (23%) PC) were analysed. Significantly more PC physicians indicated routine use (often/always) of opioids across conditions (COPD: 92% vs. 39%, fILD: 83% vs. 36%, LC: 95% vs. 76%; all p < 0.001) and significantly more PC physicians indicated routine use of benzodiazepines for COPD (33% vs. 10%) and fILD (25% vs. 12%) (both p < 0.001). Significantly more RM physicians reported routine use of a breathlessness score (62% vs. 13%, p < 0.001) and prioritised exercise training/rehabilitation for COPD (49% vs. 7%) and fILD (30% vs. 18%) (both p < 0.001). Overall, 40% of all respondents reported reading non-cancer palliative care guidelines (either carefully or looked at them briefly). Respondents who reported reading these guidelines were more likely to: routinely use a breathlessness score (χ2 = 13.8; p < 0.001), use opioids (χ2 = 12.58, p < 0.001) and refer to pulmonary rehabilitation (χ2 = 6.41, p = 0.011) in COPD; use antidepressants (χ2 = 6.25; p = 0.044) and refer to PC (χ2 = 5.83; p = 0.016) in fILD; and use a handheld fan in COPD (χ2 = 8.75, p = 0.003), fILD (χ2 = 4.85, p = 0.028) and LC (χ2 = 5.63; p = 0.018). Conclusions: These findings suggest a need for improved dissemination and uptake of jointly developed breathlessness management guidelines in order to encourage appropriate use of existing, evidence-based therapies. The lack of opioid use by RM, and continued benzodiazepine use in PC, suggest that a wider range of acceptable therapies need to be developed and trialled

Congenital Hypogonadotropic Hypogonadism Due to GNRH Receptor Mutations in Three Brothers Reveal Sites Affecting Conformation and Coupling

Congenital hypogonadotropic hypogonadism (CHH) is characterized by low gonadotropins and failure to progress normally through puberty. Mutations in the gene encoding the GnRH receptor (GNRHR1) result in CHH when present as compound heterozygous or homozygous inactivating mutations. This study identifies and characterizes the properties of two novel GNRHR1 mutations in a family in which three brothers display normosmic CHH while their sister was unaffected. Molecular analysis in the proband and the affected brothers revealed two novel non-synonymous missense GNRHR1 mutations, present in a compound heterozygous state, whereas their unaffected parents possessed only one inactivating mutation, demonstrating the autosomal recessive transmission in this kindred and excluding X-linked inheritance equivocally suggested by the initial pedigree analysis. The first mutation at c.845 C>G introduces an Arg substitution for the conserved Pro 282 in transmembrane domain (TMD) 6. The Pro282Arg mutant is unable to bind radiolabeled GnRH analogue. As this conserved residue is important in receptor conformation, it is likely that the mutation perturbs the binding pocket and affects trafficking to the cell surface. The second mutation at c.968 A>G introduces a Cys substitution for Tyr 323 in the functionally crucial N/DPxxY motif in TMD 7. The Tyr323Cys mutant has an increased GnRH binding affinity but reduced receptor expression at the plasma membrane and impaired G protein-coupling. Inositol phosphate accumulation assays demonstrated absent and impaired Gαq/11 signal transduction by Pro282Arg and Tyr323Cys mutants, respectively. Pretreatment with the membrane permeant GnRHR antagonist NBI-42902, which rescues cell surface expression of many GNRHR1 mutants, significantly increased the levels of radioligand binding and intracellular signaling of the Tyr323Cys mutant but not Pro282Arg. Immunocytochemistry confirmed that both mutants are present on the cell membrane albeit at low levels. Together these molecular deficiencies of the two novel GNRHR1 mutations lead to the CHH phenotype when present as a compound heterozygote

The Effects of Age on Inflammatory and Coagulation-Fibrinolysis Response in Patients Hospitalized for Pneumonia

Objective: To determine whether inflammatory and hemostasis response in patients hospitalized for pneumonia varies by age and whether these differences explain higher mortality in the elderly. Methods: In an observational cohort of subjects with community-acquired pneumonia (CAP) recruited from emergency departments (ED) in 28 hospitals, we divided subjects into 5 age groups (85% subjects, older subjects had modestly increased hemostasis markers and IL-6 levels (p,0.01). Conclusions: Modest age-related increases in coagulation response occur during hospitalization for CAP; however these differences do not explain the large differences in mortality. Despite clinical recovery, immune resolution may be delayed in older adults at discharge. © 2010 Kale et al

Aldo Keto Reductase 1B7 and Prostaglandin F2α Are Regulators of Adrenal Endocrine Functions

Prostaglandin F2α (PGF2α), represses ovarian steroidogenesis and initiates parturition in mammals but its impact on adrenal gland is unknown. Prostaglandins biosynthesis depends on the sequential action of upstream cyclooxygenases (COX) and terminal synthases but no PGF2α synthases (PGFS) were functionally identified in mammalian cells. In vitro, the most efficient mammalian PGFS belong to aldo-keto reductase 1B (AKR1B) family. The adrenal gland is a major site of AKR1B expression in both human (AKR1B1) and mouse (AKR1B3, AKR1B7). Thus, we examined the PGF2α biosynthetic pathway and its functional impact on both cortical and medullary zones. Both compartments produced PGF2α but expressed different biosynthetic isozymes. In chromaffin cells, PGF2α secretion appeared constitutive and correlated to continuous expression of COX1 and AKR1B3. In steroidogenic cells, PGF2α secretion was stimulated by adrenocorticotropic hormone (ACTH) and correlated to ACTH-responsiveness of both COX2 and AKR1B7/B1. The pivotal role of AKR1B7 in ACTH-induced PGF2α release and functional coupling with COX2 was demonstrated using over- and down-expression in cell lines. PGF2α receptor was only detected in chromaffin cells, making medulla the primary target of PGF2α action. By comparing PGF2α-responsiveness of isolated cells and whole adrenal cultures, we demonstrated that PGF2α repressed glucocorticoid secretion by an indirect mechanism involving a decrease in catecholamine release which in turn decreased adrenal steroidogenesis. PGF2α may be regarded as a negative autocrine/paracrine regulator within a novel intra-adrenal feedback loop. The coordinated cell-specific regulation of COX2 and AKR1B7 ensures the generation of this stress-induced corticostatic signal

Losers lose: les vrais outsiders de l'art contemporain

International audienceCette communication présente une partie des résultats d'une recherche-action menée en 2009 et 2010 pour une région française auprès d'une centaine d'artistes en situation précaire (bénéficiaires du RSA, demandeurs d'emploi). Les concepts de "mondes de l'art" et d'"outsider" d'Howard Becker sont mobilisés et réinterrogés pour décrire et comprendre les discours et les pratiques de ces artistes exclus des mondes de l'art contemporain. Les résultats de la recherche montrent que le mythe romantique de l'artiste maudit demeure extrêmement fort en même temps que très excluant chez ces artistes. Le fonctionnement des instances de légitimation des mondes de l'art contemporain, liées aux institutions publiques (commandes publiques, aides à la création...) ou au marché (galeries, agents, ...) sélectionnent aujourd'hui les artistes sur la base de projets de création qui mettent en œuvre des compétences à la fois réflexives, discursives et gestionnaires. L'analyse qualitative des discours et des pratiques des artistes les moins intégrés à ces mondes montre une distance et une divergence importantes avec les attentes et les conventions des experts et autres acteurs de ces mondes: difficultés à parler de leur travail artistique, à référencer leur discours et à positionner ce travail, à formuler, construire et présenter des projets de création, difficultés à construire leur parcours dans ces mondes... Les frontières de ces mondes de l'art semblent infranchissables alors même que ces artistes, inspirés mais isolés, ne parviennent pas à engendrer autour d'eux d'autres mondes de l'art dont ils seraient les acteurs

The Palliative Care of Patients With Incurable Cancer

Background: The purpose of palliative medicine is to optimize the quality of life of patients with incurable, progressive diseases. The care delivered in actual clinical practice is not uniform and often takes insufficient account of the currently available scientific evidence. Methods: In accordance with the methodological directives on systematic literature reviews and consensus-finding that have been issued by the German Oncology Guideline Program (Leitlinienprogranun Onkologie). a nationwide, representative group of experts updated the previously published seven chapters of the S3 (evidence-based and consensus-based) guideline and formulated new recommendations on a further eight topics in palliative care. Results: Non-drug options for the treatment of fatigue include aerobic exercise and psycho-educative methods, particularly cognitive behavioral therapy. Sleep disturbances can be treated with improved sleep hygiene and relaxation techniques, as well as with drugs: Z substances for short-term and sedating antidepressants for intermediate-term treatment. For nausea and vomiting. the first line of treatment consists of antidopaminergic drugs, such as haloperidol, or drugs with an antidopaminergic effect combined with a further receptor affinity, such as metoclopramide. For patients suffering from malignant intestinal obstruction NI% an important consideration for further treatment is whether the obstruction is complete or incomplete. Psychotherapeutic interventions are indicated for the treatment of anxiety. Conclusion: Multiple studies have confirmed the benefit of the early integration of palliative care for achieving the goals of better symptom control and maintenance of quality of life. There is currently a low or moderate quality of evidence supporting the management of certain symptoms in patients with incurable cancers

Burden and Needs of Patients with Severe GvHD from the Supportive and Palliative Care Perspective-A Literature Review

Simple Summary Patients who have been treated with an allogeneic, hematopoietic stem cell transplantation can develop severe graft-versus-host disease. This complication may place patients in a life-threatening situation, in which a curative goal of care can no longer be achieved and needs to be changed into a palliative one. In our clinical experience, this patient group is very heterogenous, with a high disease burden and special needs that are often overlooked. In this review, we summarize the current literature on the needs and burdens of patients with severe forms of graft-versus-host disease from a supportive and palliative care perspective to draw a comprehensive picture of this patient group. Despite a fundamental lack of studies, the findings suggest that the more severe the GvHD, the worse the quality of life and physical functioning. The relative void of data highlights the need for research on this special issue in order to optimize the treatment and care of patients with severe graft-versus-host disease. Graft-versus-host disease (GvHD) is a frequent, and often life-threatening, complication after an allogeneic, hematopoietic stem cell transplantation (allo-SCT).
