Introduction and objectivesLiver cirrhosis is a major public health issue associated with high morbidity and mortality. The ANSWER trial showed that long-term human albumin (LTA) infusions led to significant reduction of complications and mortality in patients with uncomplicated ascites. The present study aimed to assess the incremental cost of cirrhosis patients treated with LTA plus standard medical treatment (SMT) versus those treated with SMT from the perspective of the Mexican Social Security Institute (IMSS).Material and methodsCost of illness for patients with cirrhosis and grade 2-3 ascites treated with SMT or with SMT and LTA (following the treatment regimen from ANSWER) over a one-year period was estimated according to the IMSS perspective. Rates of treatments, complications and hospitalizations were based on results from the ANSWER trial. Unit costs from IMSS were gathered from public sources and transformed to 2020 Mexican $ (Mex$).ResultsThe use of LTA is estimated to require additional annual expenditure derived from the pharmacological cost of human albumin and by the follow up visits required for LTA administration (Mex$28,128). However, this cost may potentially be counterbalanced by the reduction in paracentesis, cirrhosis-related complications and hospitalizations which would lead to cost savings of Mex$33,417 per patient/year.ConclusionsBased on the ANSWER trial results, our study suggests that LTA may result in improved clinical outcomes and reduced costs for the IMSS when administered to cirrhosis patients with uncomplicated ascites. 相似文献

Aspirin inhibits inducible nitric oxide synthase expression and tumour necrosis factor-alpha release by cultured smooth muscle cells 总被引:3,自引:0,他引:3
Sánchez de Miguel L de Frutos T González-Fernández F del Pozo V Lahoz C Jiménez A Rico L García R Aceituno E Millás I Gómez J Farré J Casado S López-Farré A 《European journal of clinical investigation》1999,29(2):93-99
BACKGROUND: Inflammatory related cardiovascular disease, i.e. cardiac allograft rejection, myocarditis, septic shock, are accompanied by cytokine production, which stimulates the expression of inducible nitric oxide (iNOS). MATERIALS AND METHODS: The aim of the present study was to examine whether anti-inflammatory doses of acetylsalicylic acid (aspirin) could regulate iNOS protein expression in bovine vascular smooth muscle cells (BVSMCs) in culture. RESULTS: Interleukin 1 beta (IL-1 beta, 0.03 U mL-1) induced nitric oxide release by BVSMCs. Aspirin inhibited nitric oxide release from IL-1 beta-stimulated BVSMCs in a dose-dependent manner. In addition, aspirin significantly inhibited iNOS protein expression in BVSMCs and reduced the translocation of the nuclear factor-kappa B (NF-kappa B). Furthermore, aspirin and the blockade of NO generation by BVSMCs reduced the production of tumour necrosis factor alpha (TNF-alpha) by these cells. CONCLUSION: High doses of aspirin inhibited iNOS protein expression in BVSMCs and decreased NF-kappa B mobilization. The inhibition of iNOS expression by aspirin was further associated with a reduced ability of BVSMCs to produce TNF-alpha. This study could provide new mechanisms of action for aspirin in the treatment of the inflammation-related cardiovascular diseases. 相似文献

The objective of this study was to analyze the effect of the introduction of a new system of rotating shifts on nursing absenteeism. The novelty of this system is that both the time distribution and the planning and allocation of shifts is carried out according to the wishes of the participating nurses. This study was performed in the Infanta Margarita Hospital (Cordoba, Spain) and the new shift system was introduced in the first quarter of 2011. The total number of absolute hours of absence decreased from 5551 to 3289 per semester. The implementation of this new "on demand" shift system seems to have significantly reduced hours of absence. This strategy aims to reconcile nurses' working hours with their personal and family lives. 相似文献

Toxic oil syndrome (TOS) was an epidemic which broke out in Spain in 1981, caused by the ingestion of rapeseed oil denatured with 2% aniline and sold illegally as edible oil. More than 20,000 people were affected and mortality rate was 8.4%. Genetic susceptibility appears to be involved in the pathology of this disease. Several reports have described association between the chronic stage of the disease and DR-DQ antigens (DR3, DR4, DR2 and DQ8). In the present work, we have reassessed the HLA class II antigens in a well-designed case-control study. Triplets of subjects (n=265) composed by chronic patients (n=117), non-affected family members (n=71) and non-related controls (n=77) were studied. Also, HLA class II antigens were analyzed in patients who had died from TOS (n= 34) and in TOS control patients who died from other non-TOS related causes (n=13). Regarding surviving patients no significant association was found between HLA and disease. In contrast, an increase in phenotypic frequency of DR2 antigen, was found in patients who had died from TOS (73.5%) compared with the whole study group: TOS-affected alive patients (25.6%, corrected P<0.001), non-affected family members (28.5%, corrected P<0.001), non-related controls (23.9%, corrected P<0.001) and dead controls (38.4%, P=0.03). 相似文献

Iron deficiency (ID) and iron deficiency anemia (IDA) are major contributors to infant and maternal morbidity worldwide. There is limited longitudinal data on iron status in young infants and on methods to adjust iron biomarkers for inflammation. We aimed to quantify the prevalence of inflammation‐adjusted ID, anemia, and IDA over the first year in a cohort of Bolivian infants and their mothers. Healthy mother‐infant dyads were recruited from two peri‐urban hospitals. Infants provided three blood draws (2, 6–8, and 12–18 months; N = 160); mothers provided two blood draws (1 and 6–8 months postpartum [plus third anemia measurement at 12–18 months]; N = 250). Blood was analyzed for hemoglobin, ferritin, soluble transferrin receptor, C‐reactive protein (CRP), and alpha(1)‐acid glycoprotein (AGP). Iron biomarkers were adjusted for inflammation using CRP and AGP; hemoglobin cutoffs were adjusted for altitude. Inflammation (elevated CRP or AGP) was 17% among toddlers 12–18 months of age. ID (inflammation‐adjusted ferritin) increased with age (<1%, 56%, and 79% at each blood draw), as did anemia and IDA (anemia: 70%, 76%, and 81%; IDA: <1%, 46%, and 68%). Maternal ID declined from the first to second assessment (39% vs. 27%). Inflammation‐adjusted ID prevalence was up to 15 percentage points higher than unadjusted estimates. The high prevalence of ID, anemia, and IDA in this cohort of Bolivian infants beginning at 6–8 months of age suggests that early interventions may be necessary in vulnerable populations. 相似文献

BACKGROUND: This paper describes the cloning and expression of the Cupressus arizonica pollen protein Cup a 3. In addition, we present its modulation under polluted environmental conditions. Species of the Cupressaceae family are important because of their high sensitization prevalence. METHODS: Cup a 3 cloning is based on the sequence of the homologous protein Jun a 3. Cup a 3 was expressed with good yield in the methylotropic yeast Pichia pastoris. RESULTS: Recombinant Cup a 3 (rCup a 3) contains 199 amino acids, 10 potential phosphorylation sites and no glycosylation sites. By immunoblot 63% of cypress allergic patients had specific immunoglobulin E antibodies against rCup a 3 (n = 104). This major allergen is homologous to members of the pathogenesis-related proteins (PR-5 group) and contributes to the overall allergenicity of C. arizonica pollen. Our results show that the increased expression of Cup a 3 is dependent on the pollution in the area where the pollen has been collected, being higher under polluted conditions. CONCLUSIONS: Cup a 3 is a PR-5 protein derived from C. arizonica pollen. The expression of the protein under polluted conditions has a direct incidence on the pollen allergenicity, as has been demonstrated by skin tests and Radioallergosorbent test inhibition. 相似文献

The malrotation and no well fixation anomalies of the digestive tract is also frequent in older child, young and adult, with
characteristic and specific clinical presentation. Actually, the diagnostic and treatment seem to be late, after suffering
prolonged symptoms and/or in emergency. We present nine cases of anomalies in the embryonic development of the digestive tract
which were diagnosed and treated in infants or young, all above 2 years old. Eight cases were of more or less complete intestinal
malrotation; one of them was a complete malrotation with an intrinsic duodenal stenosis associated (no bands of Ladd) and
another one was a right paramesocolic hernia, always accompanied by malrotation. The association with other extra-digestive
anomalies, especially urological, was 70%. The predominant symptom was intermittent abdominal pain (IAP)—80%—sometimes accompanied
by vomiting (35%) and episodes of diarrhoea (25%). In all the cases, while the clinical background was early, diagnosis was
late. Indeed, in 60% of the cases diagnosis was made intra-operatively in emergency surgical interventions. The imaging procedures
employed were scanning and Doppler ultrasound, CT scan, and contrast gastrointestinal series (GIS). Up to 30% of errors in
interpretation occurred, although they were eventually corrected with other tests. The most reliable diagnostic procedures
were GIS and CT scan with contrast, although partial interpretation errors occurred with the latter procedure. Surgery was
essential in 80% of the pre-operative cases, and in another two it was required as a preventative measure. Post-operatively,
there was notable persistence of SBS in the cases of intestinal necrosis, and of other lesser symptoms in the rest. We conclude
that: intestinal malrotations and malfixations are still being diagnosed very late, with serious systemic consequences such
as intestinal obstructions or necroses, and prolonged clinical suffering. This could all be avoided if more attention were
paid to the digestive symptoms associated with IAP, and to subocclusion or other abdominal phenomena (distension,...), together
with, in the case of doubt about the findings with the previous procedures, the opportune imaging tests (e.g., abdominal Doppler
ultrasound, CT scan with contrast, and barium GIS). Unlike other authors, we consider that the morbidity/mortality associated
with cases of late diagnosis of these anomalies is high, and calls for earlier surgical treatment. 相似文献
