    The impact of ischemic stroke on atrial fibrillation-related healthcare cost: a systematic review

    Get PDF
    Aim: To summarize healthcare costs incurred by patients with atrial fibrillation (AF) who developed ischemic stroke, explore factors associated with increased cost and highlight the importance of anticoagulation therapy for stroke prophylaxis. / Methods: A systematic literature search of PubMed, EMBASE, Web of Science and the health economic evaluation database was conducted up to December 2015. Studies focused on the cost and/or resource utilization of ischemic stroke in patients with AF were included. Reported costs were converted to international dollars (I)andadjustedto2015values.Alongsidethenarrativereviewofincludedstudies,Spearmanscorrelation,independentsamplesttestandonewayANOVAwereusedtoexplorefactorsassociatedwithcostdifferencesbetweenstudies./Results:Sixteenstudiespublishedfromninecountrieswereidentified.Basedoncurrencyconversionratesin2015,ischemicstrokerelatedhealthcarecostswereestimatedtobeI) and adjusted to 2015 values. Alongside the narrative review of included studies, Spearman’s correlation, independent-samples t-test and one-way ANOVA were used to explore factors associated with cost differences between studies. / Results: Sixteen studies published from nine countries were identified. Based on currency conversion rates in 2015, ischemic stroke related healthcare costs were estimated to be I41,420, I12,895andI12,895 and I8,184 for high-income, upper middle-income and lower middle-income economies respectively. Local GDP per capita accounted for approximately 50% of the healthcare cost variation among countries. Major component of overall cost was from hospitalization. Ischemic stroke incurring in patients with AF ≥75 years were 2.3 times that of their younger peers (p=0.049). / Conclusions: The economic burden from ischemic stroke in patients with AF is considerable with positive association to country income. Clinicians and stakeholders should be aware of the importance of anticoagulation therapies in stroke prophylaxis, the occurrence of stroke and the downstream economic burden on an increasingly aging population

    Influenza vaccination and hospitalisation in Elderly Health Centres.

    1. A cohort of Elderly Health Centres was examined to determine whether influenza vaccination decreased hospitalisation and mortality. 2. In the influenza season, influenza vaccination reduced all-cause mortality by half and cardiorespiratory hospitalisation by a quarter. The extent to which influenza vaccination protects older people from serious morbidity and mortality needs to be confirmed in appropriately designed studies, so that scarce health care resources can be used effectivelypublished_or_final_versio

    RhoE/ROCK signaling modulates chemoresistance in HCC through IL6/JAK2/STAT3 pathways

    Conference Theme: New Horizons in Cancer Research Conference: Harnessing Breakthroughs - Targeting CuresPoster Session B: Tumor Biology: no. B40Liver cancer (hepatocellular carcinoma, HCC) is a major malignancy worldwide and the second commonest fatal cancer in Southeast Asia and China including Hong Kong, due to the high prevalence of hepatitis B viral infection. HCC is highly chemoresistant, limiting treatment options to patients. There is an urgent need to delineate the underlying molecular mechanism of HCC chemoresistance so as to identify novel therapeutic targets for this aggressive cancer. Deregulation of Rho GTPase pathway is demonstrated to play important roles in HCC tumorigenesis. RhoE/Rnd3 belongs to the Rnd subfamily of the Rho GTPase which lacks the intrinsic GTPase activity. In our previous study, we have shown that RhoE is frequently downregulated in human HCCs and acts as a metastasis suppressor, whereas ROCK2 is upregulated in human HCCs. In this study, we aimed to investigate whether RhoE is also involved in the regulation of chemoresistance in HCC. Using short-hairpin RNA and ...published_or_final_versio

    Ambient carbon monoxide and the risk of hospitalization due to chronic obstructive pulmonary disease

    Get PDF
    Data from recent experimental and clinical studies have indicated that lower concentrations of inhaled carbon monoxide might have beneficial antiinflammatory effects. Inhaled carbon monoxide has the potential to be a therapeutic agent for chronic obstructive pulmonary diseases (COPD). However, population-based epidemiologic studies of environmentally relevant carbon monoxide exposure have generated mixed findings. We conducted a time-series study in Hong Kong to estimate the association of short-term exposure to ambient carbon monoxide with emergency hospitalizations for COPD. We collected daily emergency hospital admission data and air pollution data from January 2001 to December 2007. We used log-linear Poisson models to estimate the associations between daily hospital admissions for COPD and the average daily concentrations of carbon monoxide while controlling for the traffic-related copollutants nitrogen dioxide and particulate matter with an aerodynamic diameter less than 2.5 μm. Results showed that ambient carbon monoxide was negatively associated with the risk of hospitalizations for COPD. After adjustment for levels nitrogen dioxide or particulate matter with an aerodynamic diameter less than 2.5 μm, the negative associations of carbon monoxide with COPD hospitalizations became stronger. The risk estimates were similar for female and male subjects. In conclusion, short-term exposure to ambient carbon monoxide was associated with a decreased risk of hospitalization for COPD, which suggests that carbon monoxide exposure provides some acute protection of against exacerbation of COPD.postprin

    Sequential introduction of single room isolation and hand hygiene campaign in the control of methicillin-resistant Staphylococcus aureus in intensive care unit

    <p>Abstract</p> <p>Background</p> <p>After renovation of the adult intensive care unit (ICU) with installation of ten single rooms, an enhanced infection control program was conducted to control the spread of methicillin-resistant <it>Staphylococcus aureus </it>(MRSA) in our hospital.</p> <p>Methods</p> <p>Since the ICU renovation, all patients colonized or infected with MRSA were nursed in single rooms with contact precautions. The incidence of MRSA infection in the ICU was monitored during 3 different phases: the baseline period (phase 1); after ICU renovation (phase 2) and after implementation of a hand hygiene campaign with alcohol-based hand rub (phase 3). Patients infected with extended spectrum beta-lactamase (ESBL)-producing <it>Escherichia coli </it>and <it>Klebsiella species </it>were chosen as controls because they were managed in open cubicles with standard precautions.</p> <p>Results</p> <p>Without a major change in bed occupancy rate, nursing workforce, or the protocol of environmental cleansing throughout the study period, a stepwise reduction in ICU onset nonbacteraemic MRSA infection was observed: from 3.54 (phase 1) to 2.26 (phase 2, p = 0.042) and 1.02 (phase 3, p = 0.006) per 1000-patient-days. ICU onset bacteraemic MRSA infection was significantly reduced from 1.94 (phase 1) to 0.9 (phase 2, p = 0.005) and 0.28 (phase 3, p = 0.021) per 1000-patient-days. Infection due to ESBL-producing organisms did not show a corresponding reduction. The usage density of broad-spectrum antibiotics and fluoroquinolones increased from phase 1 to 3. However a significant trend improvement of ICU onset MRSA infection by segmented regression analysis can only be demonstrated when comparison was made before and after the severe acute respiratory syndrome (SARS) epidemic. This suggests that the deaths of fellow healthcare workers from an occupational acquired infection had an overwhelming effect on their compliance with infection control measures.</p> <p>Conclusion</p> <p>Provision of single room isolation facilities and promotion of hand hygiene practice are important. However compliance with infection control measures relies largely on a personal commitment, which may increase when personal safety is threatened.</p

    A patient with asymptomatic severe acute respiratory syndrome (SARS) and antigenemia from the 2003-2004 community outbreak of SARS in Guangzhou, China.

    An asymptomatic case of severe acute respiratory syndrome (SARS) occurred early in 2004, during a community outbreak of SARS in Guangzhou, China. This was the first time that a case of asymptomatic SARS was noted in an individual with antigenemia and seroconversion. The asymptomatic case patient and the second index case patient with SARS in the 2003-2004 outbreak both worked in the same restaurant, where they served palm civets, which were found to carry SARS-associated coronaviruses. Epidemiological information and laboratory findings suggested that the findings for the patient with asymptomatic infection, together with the findings from previously reported serological analyses of handlers of wild animals and the 4 index case patients from the 2004 community outbreak, reflected a likely intermediate phase of animal-to-human transmission of infection, rather than a case of human-to-human transmission. This intermediate phase may be a critical stage for virus evolution and disease prevention.published_or_final_versio
