Thus, widely dispersed sites outside a prion's amyloid-forming region can contribute to prion character, and altering such sites can disrupt prion propagation by altering interactions with PQC factors.Our purpose was to compare conventional meta-analysis and network meta-analysis to evaluate the efficacy of different prophylactic systemic antibiotic classes in patients undergoing chemotherapy or haematopoietic stem cell transplant (HSCT). We included randomised trials if patients had cancer or were HSCT recipients and the intervention was systemic antibacterial prophylaxis. Three types of control groups were used (1) placebo, no antibiotic and non-absorbable antibiotic separately; (2) placebo and no antibiotic combined; and (3) all three combined. These gave different network geometries. Strategies synthesised were fluoroquinolone, trimethoprim-sulfamethoxazole, cephalosporin and parenteral glycopeptide versus control groups. In total 113 trials met the eligibility criteria. Where treatment effects could be estimated with both conventional and network meta-analysis, values were generally similar. However, where events were sparse, network meta-analysis could be more precise. For example, trimethoprim-sulfamethoxazole versus placebo for infection-related mortality showed a relative risk ratio (RR) of 0.55, 95% CI (0.21 to 1.44) with conventional, and RR 0.43, 95% credible region (0.20 to 0.82) with network meta-analysis. Cephalosporin versus fluoroquinolone was comparable only indirectly using the network approach and yielded RR 0.59, 95% credible region (0.28 to 1.20) to reduce bacteraemia. Incoherence (difference between direct and indirect estimates raising concerns about network meta-analysis validity) was observed with network geometry where control groups were separated, but not where control groups were combined. In this situation, conventional and network meta-analysis yielded similar results in general. Network meta-analysis results could be more precise when events were rare. Some analysis could only be performed with the network approach. These results identify scenarios in which network meta-analysis may be advantageous.Polycystic ovary syndrome (PCOS) is a common endocrine condition which often presents in adolescence. The symptoms and signs, which include obesity, acne, hirsutism and irregular menstrual periods, can have profound psychosocial, metabolic and reproductive consequences. Diagnosis in the adolescent population can be particularly difficult as there is significant overlap between the clinical features of PCOS and those of normal pubertal development. International guidelines published in 2018 have produced diagnostic criteria for adolescents to aid the physician, but there will still be many cases in which diagnostic uncertainty remains. In this article, we present a structured approach to adolescents with symptoms of PCOS, covering clinical assessment, investigation, diagnosis and management. We emphasise that intervention, with lifestyle advice and combined oral contraception should be considered even in the absence of a definitive diagnosis.Palliative sedation therapy (PST) can be a challenging area of palliative medicine because of the complex ethical considerations involved. PST is a medical therapy used for refractory symptoms in terminally ill patients and is often considered ethically justified due to the principle of double effect. Even in cases where PST is clearly indicated such as refractory cancer pain, there is potential for moral distress among clinicians. Here, we present a unique case in which multiple therapeutic options were limited in a patient with overlapping diagnoses of catatonia, medication-induced extrapyramidal symptoms, and dementia with Lewy bodies. We review how existing frameworks can be applied to similar situations and offer practical strategies to support medical decision-making regarding PST and reduce the risk of moral distress among clinicians.

Most research on starting palliative care focuses on the role of healthcare services and professional carers. However, patients and their family carers may also play a role. Especially opportunities for starting palliative care might exist among family carers. This study focused on family carers by identifying their behaviours and underlying determinants that might contribute to starting palliative care.

A qualitative study with 16 family carers of deceased persons who used palliative care was conducted using semistructured, face-to-face interviews. Constant comparison analysis was used to identify groups of behaviours that influenced starting palliative care and related determinants. The behavioural determinants were matched with concepts in existing behavioural theories. A preliminary behavioural model was developed.

Most reported behaviours regarding starting palliative care were related to communicating with the seriously ill person, other family members and professional carers; seeking information that resulted from this study can serve as a basis for the development of behavioural interventions aiming at supporting family carers in performing behaviours that might contribute to starting palliative care.Fabry disease is caused by deficient activity of α-galactosidase A, an enzyme that hydrolyzes the terminal α-galactosyl moieties from glycolipids and glycoproteins, and subsequent accumulation of glycosphingolipids, mainly globotriaosylceramide (Gb3), globotriaosylsphingosine (lyso-Gb3), and galabiosylceramide. However, there is no known link between these compounds and disease severity. see more In this study, we compared Gb3 isoforms (various fatty acids) and lyso-Gb3 analogs (various sphingosine modifications) in two strains of Fabry disease mouse models a pure C57BL/6 (B6) background or a B6/129 mixed background, with the latter exhibiting more prominent cardiac and renal hypertrophy and thermosensation deficits. Total Gb3 and lyso-Gb3 levels in the heart, kidney, and dorsal root ganglion (DRG) were similar in the two strains. However, levels of the C20-fatty acid isoform of Gb3 and particular lyso-Gb3 analogs (+18, +34) were significantly higher in Fabry-B6/129 heart tissue when compared with Fabry-B6. By contrast, there was no difference in Gb3 and lyso-Gb3 isoforms/analogs in the kidneys and DRG between the two strains.
