IntroductionTo analyse the effectiveness and safety of the indwelling pleural catheter in the management of recurrent malignant pleural effusion.Patients and methodsA prospective multicentre study was performed in 63 consecutive outpatients from four Spanish hospitals. A total of 43 men and 20 women were included, with a median age of 67 years. In seven of the cases treatment with pleurodesis had failed; in five other cases their lung was trapped; in another five cases after repeat therapeutic thoracocentesis, and the rest of them as a preference choice to pleurodesis. All patients had an indwelling pleural catheter inserted (PleurX®, Denver Biomedical).ResultsMost of patients (94.5%) reported an improvement in their respiratory symptoms (cough and dyspnoea) and their ability to function independently. Average length of the catheterisation was 45 days (6-222). Average amount of drained pleural effusion was 75 ml, with a frequency of drainage of between 3 and 4 times per week and once fortnightly. Spontaneous pleurodesis was achieved following 34.9% of procedures. No complications occurred during the insertion of the catheter. The post-catheterisation complications were empyema (3 cases), chest pain (2 cases), and tumour metastasis (3 cases).ConclusionsThe use of an indwelling pleural catheter is an effective palliative treatment in the outpatient management for patients suffering malignant pleural effusion. It is also a simple treatment that can be easily applied, does not require hospitalisation and can be easily managed by the patient at home, with a low rate of complications. 相似文献
The possible effect of Government Consumption (a component of Gross Domestic Product (GDP)) on attainment of the hunger Millennium Development Goal (MDG1) was analyzed by evaluating the effect of macroeconomic, social, demographic and policy variables on average undernourished population. Eighty-four developing countries with data available on undernourished population were included in an ecological study. Regression models were applied to explore possible determinants of Undernourished between 1990 and 2004 and consequent achievement of the projected 2004 MDG1. In 2004, 1.4% of the overall undernourished population in the studied countries [70.16 million people] was in excess of the projected level required to meet MDG1. The multiple linear regression showed significant associations between Undernourished and poverty levels, the Gini Index, rural population and Government Consumption. The multiple logistic regression showed significant associations between achievement of projected 2004 MDG1 levels and Government Consumption and the Gini Index. The significant associations between Undernourished and Government Consumption suggest that the effects of GDP components on social conditions call for more thorough research and that policymakers such as governments and international financial institutions need to ensure that changes in distributive and redistributive policies do not negatively affect the possibility of achieving MDG1. 相似文献
Background: Hemoglobin solutions combine volume effect, oxygen-carrying capacity, and vasoactive properties, the latter facilitating restoration of global hemodynamics but endangering microvascular resuscitation. Hemoglobin-evoked vasoconstriction probably is due to nitric oxide scavenging, which can be reduced by genetic modifications of the heme pocket. This study compares resuscitation with a nonhemoglobin colloid and two recombinant hemoglobin solutions with wild-type and reduced nitric oxide-scavenging capacity.
Methods: Twenty-seven awake Syrian golden hamsters fitted with dorsal skinfold chambers underwent a 30 min-hemorrhagic shock (mean arterial pressure [MAP] 30-35 mmHg) and resuscitation with shed blood volume of either 6% dextran 60 (Biophausia, Uppsala, Sweden), recombinant hemoglobin 1.1 (rHb1.1; wild-type nitric oxide-scavenging capacity; 10 g/dl), or recombinant hemoglobin 2.0 (rHb2.0; reduced nitric oxide-scavenging capacity; 10 g/dl; both Baxter Healthcare, Boulder, CO). Macrohemodynamic and laboratory parameters were assessed; microvascular parameters in the skinfold chamber were analyzed by intravital microscopy.
Results: Hemorrhagic shock reduced functional capillary density (FCD) by 70% and caused significant metabolic acidosis. Colloid resuscitation led to incomplete recovery of MAP and FCD. Infusion of rHb1.1 completely restored MAP but not FCD, with the smallest arteriolar diameters found in this group. FCD was restored best by resuscitation with rHb2.0, although MAP was lower than in rHb1.1-treated animals. Metabolic acidosis was resolved by both hemoglobin solutions, but not by dextran. 相似文献
Objective To investigate anethol trithione therapic efficiency on dry eye. Methods It was a prospective random double-blind controlled study. Eighty cases diagnosed dry eye in Ocular Surface Out-patient Clinic of Xiamen University Affiliated Xiamen Eye Center from 2006 to 2008 were divided into two groups: anethol trithione group and control group, 40 cases in each group. Every group was then divided into two subgroups: weak dry eye subgroup, middle and severe dry eye subgroup. All groups had been added with 0.05% refresh drops. All patients had been detected and evaluated by subjective symptoms of dry eye, visual acuity,corneal fluorescent staining(F1), break-up time(BUT) and Schirmer Ⅰ test (SⅠT) at pre-therapy and 3,7,28 d of post-therapy. All groups had been compared and analyzed by F test and sample mean difference (SMD) or median difference (MD) comparison between pre-therapy and post-therapy. Results Except of tear and red eye, the other subjective symptoms of dry eye, F1, BUT and SⅠT of weak dry eye subgroup of both groups had been improved at 7 d after therapy. Only those of middle and severe dry eye subgroup of anethol trithione group had been improved at 7 d after therapy compared with those of pre-therapy: SMD=0.96 (visual tiredness), 1.26 (dry and unsmooth sensation), 0.82 (foreign body sensation), 1.28 (burning sensation), 1.05 (photophobia), 1.48 ( pain ) ; MD=0.30 (visual acuity), 4.00 (F1) ,5.00 (BUT), 5.00 (SⅠT) [F=15.30 (visual tiredness), 15.68 (dry and unsmooth sensation ), 13.56 (foreign body sensation), 20. 91 ( burning sensation ), 18.90 (photophobia), 27.22 ( pain ), 10.54 (visual acuity), 188.21 (F1) ,261.76 (BUT) ,269.05 (SⅠT) ;P<0. 05]. Those of middle and severe dry eye subgroup of control group hadn't significantly been improved at 28 d after therapy: SMD=0.10 (visual tiredness) ,0.16 (dry and unsmooth sensation) ,0.09 (foreign body sensation) ,0.38 ( burning sensation ), 0.24(photophobia) ,0.36 (pain) ,0.23 (red eye) ; MD=0.10 (visual acuity) ,0.50(F1) ,0.50(BUT), 0.50(SⅠT) [F=1.76 (visual tiredness), 1.61 (dry and unsmooth sensation), 1.02 (foreign body sensation),2.39 (burning sensation), 2.42 (photophobia), 2.73 ( pain ), 2.55 ( red eye ), 1.46 ( visual acuity) ,2.35 (F1) ,2.90 (BUT) ,2.76 (SⅠT) ; P>0.05]. SⅠT of anethol trithione group had been improved more significantly after therapy (F=13.77, P<0.05). Conclusion Anethol trithione could significantly improve middle and severe dry eye patients' symptoms and signs whose lacrimal gland function survival and it has clinical application value. 相似文献
This study aimed to determine whether a weight-adjusted dose of subcutaneous enoxaparin is as effective and safe as oral acenocoumarol for the secondary prophylaxis of pulmonary embolism. Three hundred and eighty consecutive noncancer outpatients hospitalized with an episode of symptomatic pulmonary embolism selected treatment with acenocoumarol or enoxaparin at a dose of 1 mg/kg once daily after being informed of the type of administration and expected frequency of laboratory monitoring for both medicinal products. Endpoints were symptomatic recurrent thromboembolic events evaluated by standard objective testing, and a composite endpoint of recurrent venous thromboembolism, major bleeding, and death from any cause. One hundred and ninety-nine patients (52%) chose acenocoumarol therapy and 181 chose enoxaparin monotherapy. Four patients in the enoxaparin group (2.2%) and six patients in the acenocoumarol group (3%) had an objective thromboembolic recurrence (hazard ratio, 1.35; 95% confidence interval, 0.38-4.79; P = 0.64). Nine patients in the enoxaparin group (5.0%) had a hemorrhagic complication compared with 11 in the acenocoumarol group (5.5%) (P = 0.81). The hospital length of stay was shorter with enoxaparin compared with acenocoumarol (11 versus 16 days, P = 0.0001). Enoxaparin is as effective and safe as acenocoumarol in the secondary prevention of recurrent thromboembolic disease and is associated with shorter hospitalization. 相似文献
