Which Cost Components Influence the Cost of Palliative Care in the Last Hospitalization? A Retrospective Analysis of Palliative Care Versus Usual Care at a Swiss University Hospital.

CONTEXT: Although the number of studies on the economic impact of palliative care (PC) is growing, the great majority report costs from North America. OBJECTIVES: We aimed to provide a comprehensive overview of PC hospital cost components from the perspective of a European mixed funded health care system by identifying cost drivers of PC and quantifying their effect on hospital costs compared to usual care (UC). METHODS: We performed a retrospective, observational analysis examining cost data from the last hospitalization of patients who died at a large academic hospital in Switzerland comparing patients receiving PC vs. UC. RESULTS: Total hospital costs were similar in PC and UC with a mean difference of CHF -2777 [95% CI -12,713 to 8506, P = 0.60]. Average costs per day decreased by CHF -3224 [95% CI -3811 to -2631, P < 0.001] for PC patients with significant reduction of costs for diagnostic intervention and medication. Higher cost components for PC patients were catering, room, nursing, social counseling, and nonmedical therapists. In sensitivity analyses, when we restricted PC exposure to three days from admission, total costs and average costs per day were significantly lower for PC. CONCLUSION: Studies measuring the impact of PC on hospital costs should analyze various cost components beyond total costs to understand wanted and potentially unwanted cost-reducing effects. An international definition of a set of cost components, specific for cost-impact PC studies, may help avoid superficial and potentially dangerous cost discussions.

Does Time for (in)Direct Nursing Care Activities at the End of Life for Patients With or Without Specialized Palliative Care in a University Hospital Differ? A Retrospective Analysis.

BACKGROUND: Nurses' end of life (EoL) care focuses on direct (eg, physical) and indirect (e,g, coordination) care. Little is known about how much time nurses actually devote to these activities and if activities change due to support by specialized palliative care (SPC) in hospitalized patients. AIMS: (1) Comparing care time for EoL patients receiving SPC to usual palliative care (UPC);(2) Comparing time spent for direct/indirect care in the SPC group before and after SPC. METHODS: Retrospective observational study; nursing care time for EoL patients based on tacs® data using nonparametric and parametric tests. The Swiss data method tacs measures (in)direct nursing care time for monitoring and cost analyses. RESULTS: Analysis of tacs® data (UPC, n = 642; SPC, n = 104) during hospitalization before death in 2015. Overall, SPC patients had higher tacs® than UPC patients by 40 direct (95% confidence interval [CI]: 5.7-75, P = .023) and 14 indirect tacs® (95% CI: 6.0-23, P < .001). No difference for tacs® by day, as SPC patients were treated for a longer time (mean number of days 7.2 vs 16, P < .001).Subanalysis for SPC patients showed increased direct care time on the day of and after SPC (P < .001), whereas indirect care time increased only on the day of SPC. CONCLUSIONS: This study gives insight into nurses' time for (in)direct care activities with/without SPC before death. The higher (in)direct nursing care time in SPC patients compared to UPC may reflect higher complexity. Consensus-based measurements to monitor nurses' care activities may be helpful for benchmarking or reimbursement analysis.

Livedoid vasculopathy: does hyperhomocysteinaemia play an aetiological role?

BACKGROUND: Livedoid vasculopathy (LV) has been shown to be associated with hypercoagulability. However, relevant genetic and exogenous thrombophilic factors are not fully determined. OBJECTIVES: To evaluate the frequency of hyperhomocysteinaemia (HHCE) and genotypes of hypercoagulative factors in LV patients. MATERIAL AND METHODS: Plasma homocysteine level was measured in 42 LV patients. Polymorphism of MTHFR (677C > T and 1298A > C), PAI1 (-675 5G/4G and -844A > G), and F2 (20210G > A), and the F5 Leiden mutation, as well as biochemical parameters for hypercoagulability, were analysed. RESULTS: Of the LV patients, 62% revealed mild HHCE. Polymorphisms of MTHFR were observed in 75% and 56% and the PAI1 -675 5G/4G polymorphism in 100% and 83% of patients with and without HHCE, respectively. All LV patients with renal failure had mild HHCE. A high level of comorbidity of hypertension (99%) and diabetes type 2 (44%) were noted. CONCLUSION: HHCE seems to play a major pathogenetic role in LV. A high prevalence of further procoagulative factors might support the view that LV is a "complex disease".

The LDL receptor-related protein (LRP1/A2MR) and coronary atherosclerosis--novel genomic variants and functional consequences.

The LDL receptor-related protein/alpha 2-macroglobulin receptor (LRP1/A2MR) is a multifunctional cell-surface glycoprotein that endocytoses several structurally and functionally distinct ligands. In clinical studies different genomic variants of the LRP1/A2MR and its role in the development of degenerative diseases like atherosclerosis or Alzheimer's disease were studied. We screened for novel genomic variants of LRP1/A2MR and investigated the importance of these variants in 214 coronary patients suffering from myocardial infarction as well as in 224 healthy controls. We detected a novel C>G polymorphism at position -25 in the functionally important promoter region of LRP1/A2MR. This polymorphism (c.1-25C>G) leads to the creation of a new GC-box, recognized by the constitutively expressed SP 1 transcription factor. Investigating the LRP1/A2MR gene expression with respect to this polymorphism, carriers of the mutant G-allele were found to have a higher mRNA expression level. A novel polymorphism in exon 22 (c.4012C>T), and two novel polymorphisms in intron 24 (IVS24+123C>A and IVS24+690G>A) associated with a previously described polymorphism in exon 61 (c.10249G>A), were related to the development of myocardial infarction. Two novel rare genetic variants of exon 88 (c.13933C>T) and intron 88 (IVS88+15G>A) were identified in four patients with severe coronary symptoms. However, the LRP1/A2MR gene expression was found to be independent of all identified novel genomic variants as well as other previously described changes (A217V, A775P, D2080N, D2632E, G4379S) except the promoter polymorphism.

Identification and molecular cytogenetic characterization of a novel complex Y chromosome rearrangement in a boy with disorder of sexual development.

Ambiguous genitalia or disorder of the sexual development is a birth defect where the external genitals do not have the typical appearance of either a male or female. Here we report a boy with ambiguous genitalia and short stature. The cytogenetic analysis by G-banding revealed a small Y chromosome and an additional material on the 15p arm. Further, molecular cytogenetic analysis by Fluorescence in situ hybridization (FISH) using whole chromosome paint probes showed the presence of Y sequences on the 15p arm, confirming that it is a Y;15 translocation. Subsequent, FISH with centromere probe Y showed two signals depicting the presence of two centromeres and differing with a balanced translocation. The dicentric nature of the derivative 15 chromosome was confirmed by FISH with both 15 and Y centromeric probes. Further, the delineation of the Y chromosomal DNA was also done by quantitative real time PCR. Additional Y-short tandem repeat typing was performed to find out the extent of deletion on small Y chromosome. Fine mapping was carried out with 8 Y specific BAC clones which helped in defining the breakpoint regions. MLPA was performed to check the presence or absence of subtelomeric regions and SHOX regions on Y. Finally array CGH helped us in confirming the breakpoint regions. In our study we identified and characterized a novel complex Y chromosomal rearrangement with a complete deletion of the Yq region and duplication of the Yp region with one copy being translocated onto the15p arm. This is the first report of novel and unique Y complex rearrangement showing a deletion, duplication and a translocation in the same patient. The possible mechanism of the rearrangement and the phenotype-genotype correlation are discussed.

Minimal phenotype in a girl with trisomy 15q due to t(X;15)(q22.3;q11.2) translocation.

Few cases of de novo unbalanced X;autosome translocations associated with a normal or mild dysmorphic phenotype have been described. We report a 3-year-old dizygotic female twin with prenatally ascertained increased nuchal translucency. Prenatal chromosome studies revealed nearly complete trisomy 15 due to a de novo unbalanced translocation t(X;15)(q22;q11.2) confirmed postnatally. A mild phenotype was observed with normal birth measurements, minor facial dysmorphic features (hypertelorism, short broad nose, and a relatively long philtrum), and moderate developmental delay at the age of 3 years in comparison to her male fraternal twin. Replication timing utilizing BrdU and acridine-orange staining showed that the der(X) chromosome was late-replicating with variable spreading of inactivation into the translocated 15q segment. The der(X) was determined to be of paternal origin by analyses of polymorphic markers and CGG-repeat at FMR1. Methylation analysis at the SNRPN locus and analysis of microsatellites on 15q revealed paternal isodisomy with double dosage for all markers and the unmethylated SNRPN gene. The Xq breakpoint was mapped within two overlapping BAC clones RP11-575K24 and RP13-483F6 at Xq22.3 and the 15q breakpoint to 15q11.2, within overlapping clones RP11-509A17 and RP11-382A4 that are all significantly enriched for LINE-1 elements (36.6%, 43.0%, 26.6%, 22.0%, respectively). We speculate that the attenuated phenotype may be due to inactivation spreading into 15q, potentially facilitated by the enrichment of LINE-1 elements at the breakpoints. In silico analysis of breakpoint regions revealed the presence of highly identical low-copy repeats (LCRs) at both breakpoints, potentially involved in generating the translocation.
