Deaths in France: Characteristics, place of death, hospitalisations and use of palliative care during the year before death.

AIM: Only limited data are available concerning the diseases managed and the hospital pathway before death. The aim of this study was to describe diseases, hospitalisations, and use of palliative care one year before death as well as place of death in France. METHODS: French health insurance general scheme beneficiaries who died in 2013 were identified in the National Health Insurance Information System (SNIIRAM) with a selection of information concerning their various hospital stays, including hospital palliative care (HPC) and nursing home care. Diseases were identified by algorithms from reimbursement data recorded in the SNIIRAM database. RESULTS: A total of 347 253 people were included (61% of all deaths in France). The mean age of death was 77 years (SD 15.1). Diseases managed before death were cardiovascular/neurovascular diseases (56%), cancers (42%), neurological and degenerative diseases (25%), diabetes (21%) and chronic respiratory diseases (20%). Deaths occurred in hospital in 60% of cases: 51% in acute wards, 6% in rehabilitation units, 3% in hospital at home (HaH), and 13% in nursing homes. During the year preceding death, 84% of people were hospitalised at least once and 29% received HPC. People receiving HPC more often died in hospital than people not receiving HPC (69% vs. 44%). CONCLUSION: Health administrative data from the SNIIRAM database can refine our knowledge of the care pathway prior to death and of the use of hospital palliative care and can be useful to evaluate the new governmental palliative care plan recently deployed in France.

In vitro expansion of tumour cells derived from blood and tumour tissue is useful to redefine personalized treatment in non-small cell lung cancer patients.

The clinical development of locally and advanced non-small cell lung cancer (NSCLC) suffers from a lack of biomarkers as a guide in the selection of optimal prognostic prediction. Circulating Tumour Cells (CTCs) are correlated to prognosis and show efficacy in cancer monitoring in patients. However, their enumeration alone might be inadequate; it might also be critical to understand the viability, the apoptotic state and the kinetics of these cells. Here, we report what we believe to be a new and selective approach to visually detect tumour specific CTCs. Firstly, using labelled human lung cancer cells, we detected a specific density interval in which NSCL-CTCs were concentrated. Secondly, to better characterize CTCs in respect to their heterogeneous composition and tumour reference, blood and tumour biopsy were performed on specimens taken from the same patient. The approach consisted in comparing phenotype profile of CTCs, and their progenitor Tumour Stem Cells, (TSCs). Moreover, NSCL-CTCs were cultivated in short-time human cultures to provide response to drug sensitivity. Our bimodal approach allowed to reveal two items. Firstly, that one part of a tumour, proximal to the bronchial structure, displays a predominance of CD133+. Secondly, specific NSCL-CTCs Epithelial Cell Adhesion Molecule (EpCAM)+CD29+ can be used as a negative prognostic factor as well the high expression of CTCs EpCAM+. These data were confirmed by drug-sensitivity tests, in vitro, and by the survival curves, in vivo.

Massive pulmonary embolism as a rare complication of a stab in the inguinal region in a HIV-positive patient: a case report.

OBJECTIVE: Venous thromboembolism (VTE) is a severe preventable disease; HIV-infection represents a prothrombotic condition, because of specific factors due to the virus itself, the host response and the antiretroviral therapy. Our aim is to raise awareness of thromboembolic risk when dealing with HIV-positive patients presenting to the Emergency Department for treatment of injuries, even though small. CASE REPORT: We present a case of a 33-year-old woman suffering from HIV-infection who presented to the Emergency Department with two small stab wounds. Laboratory tests and radiologic examinations were normal. About 8 hours after admission the patient developed a syncopal attack: a CT scan performed after hemodynamic stabilization revealed a massive pulmonary embolism (PE); the patient was then transferred to the Intensive Care Unit and treated with systemic thrombolysis. CONCLUSIONS: This case confirms that HIV-positive patients carry a higher risk for VTE and PE compared to general population, similarly to patients suffering from cancer: emergency physicians must be aware even in case of minor wounds.

Sigma-2 receptor expression in bovine papillomavirus-associated urinary bladder tumours.

The expression of sigma-2 receptors was investigated in nine urothelial tumours of the urinary bladder of cattle. Each tumour was associated with the presence of DNA of bovine papillomavirus type-2 (BPV-2) and expression of the E5 viral oncoprotein. Five tumours were classified as low-grade carcinoma on the basis of morphological criteria and calculation of mean nuclear area (MNA) and mean nuclear perimeter (MNP). Four tumours were classified as high-grade carcinoma. Sigma-2 receptors were overexpressed in both types of carcinoma. In control normal bovine bladder tissue the density of receptors (expressed as the B(max)) was 0.37 pmol/mg of protein. Low-grade carcinomas had a mean B(max) of 1.37+/-0.32 pmol/mg of protein (range 1.03-1.86) and in high-grade carcinomas the mean B(max) was 10.9+/-2.8 pmol/mg of protein (range 8.2-14). The difference in B(max) between low- and high-grade carcinomas was statistically significant (P=0.0001).

Ferritin heavy chain (FHC) is up-regulated in papillomavirus-associated urothelial tumours of the urinary bladder in cattle.

The up-regulation of ferritin heavy chain (FHC) is reported in six papillary and in four invasive urothelial tumours of the urinary bladder of cattle grazing on mountain pastures rich in bracken fern. All tumours contained sequence of bovine papillomavirus type-2 (BPV-2) as determined by polymerase chain reaction (PCR) analyses and validated by direct sequencing of the amplified products. The oncoprotein E5 was also detected in these tumours by immunoprecipitation and by immunofluorescence and laser scanning confocal microscopy. Expression of FHC was evaluated by western blot analysis, reverse transcriptase (RT) PCR, real-time RT-PCR and immunohistochemistry. The oligonucleotide sequence of the bovine ferritin amplicons was identical to that of human ferritin. Nuclear overexpression of p65, an important component of nuclear factor kappaB (NF-kappaB) transcription factors, was also observed. These findings suggest that FHC up-regulation may be mediated by activation of NF-kappaB and that in turn this may be related to the resistance of bovine papillomavirus type-2 (BPV-2) infected urothelial cells to apoptosis.

Assessing modifications of the intestinal bacterial flora in patients on long-term oral treatment with bacampicillin or amoxicillin: a random study.

The authors conducted a randomized trial on 16 patients to evaluate intestinal aerobic microfloral changes after prolonged oral treatment with bacampicillin (b.) (16 g/die) or amoxicillin (a.) (2 g/die). The analysis showed a quantitative reduction of isolates in 6 patients: 2 patients were treated with b. while 4 with a. (Odd ratio, O.R. = 3). Mean values of CFU presented as well a more evident reduction in a.-treated patients. From the qualitative point of view, bacteria modifications occurred in one patient treated with b. and 3 with a, (O.R. = 4.2). Bacterial changes, although not statistically significant, were thus greater in patients treated with a. than b.
