A prospective, multicentre, observational cohort study of analgesia and outcome after pneumonectomy
Background Meta-analysis and systematic reviews of epidural compared with paravertebral blockade analgesia techniques for thoracotomy conclude that although the analgesia is comparable, paravertebral blockade has a better short-term side-effect profile. However, reduction in major complications including mortality has not been proven.
Methods The UK pneumonectomy study was a prospective observational cohort study in which all UK thoracic surgical centres were invited to participate. Data presented here relate to the mode of analgesia and outcome. Data were analysed for 312 patients having pneumonectomy at 24 UK thoracic surgical centres in 2005. The primary endpoint was a major complication.
Results The most common type of analgesia used was epidural (61.1%) followed by paravertebral infusion (31%). Epidural catheter use was associated with major complications (odds ratio 2.2, 95% confidence interval 1.1–3.8; P=0.02) by stepwise logistic regression analysis.
Conclusions An increased incidence of clinically important major post-pneumonectomy complications was associated with thoracic epidural compared with paravertebral blockade analgesia. However, this study is unable to provide robust evidence to change clinical practice for a better clinical outcome. A large multicentre randomized controlled trial is now needed to compare the efficacy, complications, and cost-effectiveness of epidural and paravertebral blockade analgesia after major lung resection with the primary outcome of clinically important major morbidity
The timing of death in patients with tuberculosis who die during anti-tuberculosis treatment in Andhra Pradesh, South India
Background: India has 2.0 million estimated tuberculosis (TB) cases per annum with an estimated 280,000 TBrelated
deaths per year. Understanding when in the course of TB treatment patients die is important for
determining the type of intervention to be offered and crucially when this intervention should be given. The
objectives of the current study were to determine in a large cohort of TB patients in India:- i) treatment outcomes
including the number who died while on treatment, ii) the month of death and iii) characteristics associated with
“early” death, occurring in the initial 8 weeks of treatment.
Methods: This was a retrospective study in 16 selected Designated Microscopy Centres (DMCs) in Hyderabad,
Krishna and Adilabad districts of Andhra Pradesh, South India. A review was performed of treatment cards and
medical records of all TB patients (adults and children) registered and placed on standardized anti-tuberculosis
treatment from January 2005 to September 2009.
Results: There were 8,240 TB patients (5183 males) of whom 492 (6%) were known to have died during treatment.
Case-fatality was higher in those previously treated (12%) and lower in those with extra-pulmonary TB (2%). There
was an even distribution of deaths during anti-tuberculosis treatment, with 28% of all patients dying in the first 8
weeks of treatment. Increasing age and new as compared to recurrent TB disease were significantly associated
with “early death”.
Conclusion: In this large cohort of TB patients, deaths occurred with an even frequency throughout anti-TB
treatment. Reasons may relate to i) the treatment of the disease itself, raising concerns about drug adherence,
quality of anti-tuberculosis drugs or the presence of undetected drug resistance and ii) co-morbidities, such as HIV/
AIDS and diabetes mellitus, which are known to influence mortality. More research in this area from prospective
and retrospective studies is needed
The Cost-Effectiveness of Tuberculosis Preventive Therapy for HIV-Infected Individuals in Southern India: A Trial-Based Analysis
Regimens for isoniazid-based preventive therapy (IPT) for tuberculosis (TB) in HIV-infected individuals have not been widely adopted given concerns regarding efficacy, adherence and drug resistance. Further, the cost-effectiveness of IPT has not been studied in India.We used an HIV/TB model to project TB incidence, life expectancy, cost and incremental cost-effectiveness of six months of isoniazid plus ethambutol (6EH), thirty-six months of isoniazid (36H) and no IPT for HIV-infected patients in India. Model input parameters included a median CD4 count of 324 cells/mm(3), and a rate ratio of developing TB of 0.35 for 6EH and 0.22 for 36H at three years as compared to no IPT. Results of 6EH and 36H were also compared to six months of isoniazid (6H), three months of isoniazid plus rifampin (3RH) and three months of isoniazid plus rifapentine (3RPTH).Projected TB incidence decreased in the 6EH and 36H regimens by 51% and 62% respectively at three-year follow-up compared to no IPT. Without IPT, projected life expectancy was 136.1 months at a lifetime per person cost of 100 (incremental cost-effectiveness ratio (ICER) of 55 (ICER of $3,120/YLS). The projected clinical impact of 6EH was comparable to 6H and 3RH; however when compared to these other options, 6EH was no longer cost-effective given the high cost of ethambutol. Results were sensitive to baseline CD4 count and adherence.Three, six and thirty-six-month regimens of isoniazid-based therapy are effective in preventing TB. Three months of isoniazid plus rifampin and six-months of isoniazid are similarly cost-effective in India, and should be considered part of HIV care
Assessing Tuberculosis Case Fatality Ratio: A Meta-Analysis
Background: Recently, the tuberculosis (TB) Task Force Impact Measurement acknowledged the need to review the assumptions underlying the TB mortality estimates published annually by the World Health Organization (WHO). TB mortality is indirectly measured by multiplying estimated TB incidence with estimated case fatality ratio (CFR). We conducted a meta-analysis to estimate the TB case fatality ratio in TB patients having initiated TB treatment. Methods: We searched for eligible studies in the PubMed and Embase databases through March 4(th) 2011 and by reference listing of relevant review articles. Main analyses included the estimation of the pooled percentages of: a) TB patients dying due to TB after having initiated TB treatment and b) TB patients dying during TB treatment. Pooled percentages were estimated using random effects regression models on the combined patient population from all studies. Main Results: We identified 69 relevant studies of which 22 provided data on mortality due to TB and 59 provided data on mortality during TB treatment. Among HIV infected persons the pooled percentage of TB patients dying due to TB was 9.2% (95% Confidence Interval (CI): 3.7%-14.7%) and among HIV uninfected persons 3.0% (95% CI: 21.2%-7.4%) based on the results of eight and three studies respectively providing data for this analyses. The pooled percentage of TB patients dying during TB treatment was 18.8% (95% CI: 14.8%-22.8%) among HIV infected patients and 3.5% (95% CI: 2.0%-4.92%) among HIV uninfected patients based on the results of 27 and 19 studies respectively. Conclusion: The results of the literature review are useful in generating prior distributions of CFR in countries with vital registration systems and have contributed towards revised estimates of TB mortality This literature review did not provide us with all data needed for a valid estimation of TB CFR in TB patients initiating TB treatmen
Genetic testing for TMEM154 mutations associated with lentivirus susceptibility in sheep
Stefan Hiendleder is a member of the International Sheep Genomics ConsortiumIn sheep, small ruminant lentiviruses cause an incurable, progressive, lymphoproliferative disease that affects millions of animals worldwide. Known as ovine progressive pneumonia virus (OPPV) in the U.S., and Visna/Maedi virus (VMV) elsewhere, these viruses reduce an animal’s health, productivity, and lifespan. Genetic variation in the ovine transmembrane protein 154 gene (TMEM154) has been previously associated with OPPV infection in U.S. sheep. Sheep with the ancestral TMEM154 haplotype encoding glutamate (E) at position 35, and either form of an N70I variant, were highly-susceptible compared to sheep homozygous for the K35 missense mutation. Our current overall aim was to characterize TMEM154 in sheep from around the world to develop an efficient genetic test for reduced susceptibility. The average frequency of TMEM154 E35 among 74 breeds was 0.51 and indicated that highly-susceptible alleles were present in most breeds around the world. Analysis of whole genome sequences from an international panel of 75 sheep revealed more than 1,300 previously unreported polymorphisms in a 62 kb region containing TMEM154 and confirmed that the most susceptible haplotypes were distributed worldwide. Novel missense mutations were discovered in the signal peptide (A13V) and the extracellular domains (E31Q, I74F, and I102T) of TMEM154. A matrix-assisted laser desorption/ionization–time-of flight mass spectrometry (MALDI-TOF MS) assay was developed to detect these and six previously reported missense and two deletion mutations in TMEM154. In blinded trials, the call rate for the eight most common coding polymorphisms was 99.4% for 499 sheep tested and 96.0% of the animals were assigned paired TMEM154 haplotypes (i.e., diplotypes). The widespread distribution of highly-susceptible TMEM154 alleles suggests that genetic testing and selection may improve the health and productivity of infected flocks.Michael P. Heaton, Theodore S.

Health and Environmental Safety Aspect of Construction Project
Generally projects are classified as Major Project, Medium Project and Minor Project. According to the size of construction, Health and Environment related concerns are considered. All type of construction must follow Building acts as stated in National Building Code of India thereof all health and environmental provisions for safety of, societal beings and his environment, are made, beside these things there are few such issues which are unpleasantly encountered. The aim of this paper is to propose a way and tactics to resolve such issues in a constructive and productive manner. The objective of this paper is to make us aware about the common environmental terms, to state their legal obligations and our responsibilities in relation to environmental legislation, to recognize common environmental impacts on construction sites in general and potential impacts resulting from the individuals work activities in particular, to identify the currently accepted environmental management best practices for relevant workplace activities. It contains remedial measures and safety precautions at different stages of project, like planning, consulting and execution and post-construction operation. The committees recommended environmental clearance to the controversial project based on several conditions and promises of strict monitoring. It is seen that human health and the health of the environment are mutually interdependent. Human health is seen by many as the justification for the impact assessment of development projects and for environmental protection. It has become very important to take these health and environment related problems seriously.
Mass Housing techniques using in India
In this topic of mass housing the Shortage of housing accommodation is assuming on alarming proportion particularly in the Indian metropolitan cities as a result of unique rise in population and unending influx of migrants. Mass housing construction carried out on a war footing could help in mitigating the problem to a great extent. In pragmatic approach, encompassing considerations related to locations of new construction, provision of transit camps, financial and operational incentives and finally adoption of innovative construction technologies, is highly essential and the same could lead to expeditious, cost - effective and quality construction. In the housing scenario in India with particular reference to Mumbai, along with the measures taken in the past to tackle the same. The various technologies that were adopted for mall housing construction in Mumbai and which resulted in speedy completion of some 49,000 tenements in a short period are decried. The authors argue that a storing political will, provision of financial and operational incentives and adoption of innovative technologies of construction could go a long way in mitigating the housing problem.
