The frequency of multiple-antibiotic resistant bacteria has been increasing in recent years. Among the gram-negative bacteria Pseudomonas aeruginosa (P. aeruginosa) shows a great propensity for the development of multidrug resistance mechanisms. The objective of this study was to identify the profile of susceptibility to antibiotics, the frequency of multidrug resistance and the cross-resistance between drugs of P. aeruginosa strains in two tertiary hospitals in Recife, Pernambuco.The study was carried out between September 2004 and January 2006. The antimicrobial susceptibility testing was performed in 304 strains of P. aeruginosa by the disc diffusion method in accordance with National Committee for Clinical and Laboratory Standards (NCCLS) guidelines.The most frequent materials were urine (26.7%) and respiratory tract secretion (26.1%) The antibiotics tested and their respective susceptibilities were as follows: piperacillin-tazobactam (66.2%); aztreonam (59.8%); amikacin (59.4%); meropenem (58.2%); imipenem (57.7%); ciprofloxacin (49.7%); gentamicin and cefepime (48.6%); ceftazidime (30%) and cefotaxime (6.8%). A high prevalence of multi-resistance was detected. Half (49.7%) the strains showed resistance to three or more antibiotics and 28% were resistant to six antimicrobials or more. Also, cross-resistance between the beta-lactams (carbapenems and piperacilin/tazobactam) and aminoglicosides and quinolones was between 22.9% and 38.1%. These drugs are commonly combined in the treatment of severe infections caused by Pseudomonas, which reflects the difficulty in choosing the appropriate option for combination therapy.The frequency of multidrug-resistant strains of P. aeruginosa in this study was similar to other hospitals in Brazil and higher than in other countries. In order to reduce the frequency of these multiresistant clones, epidemiologic surveillance and the rational use of antibiotic protocols need to be urgently implemented.

Establish the clinical, epidemiological and laboratorial characteristics of septic patients in an intensive care unit (ICU) of a tertiary care private hospital from Pernambuco, in the northeast of Brazil.Cohort study without intervention that included adult patients admitted in the ICU with sepsis or that developed it during ICU stay, during a 6-month period. The patients were followed during all ICU stay period. Laboratory and clinical data were collected after sepsis diagnosis. ICU admission APACHE II score and the SOFA score during the three first days after inclusion in the study were collected.The study included 199 patients, of whom 67.8% were older than 65 years of age. More than a half (56.3%) survived the septic episode, mean APACHE II was 18.2 6.3 and mean SOFA score was 6.3 3.7. The disease related to the admission in ICU was medical in 85.4%, and the majority of patients had a chronic associated disease. In 79.3% the lungs were the source of sepsis and in 40% of patients the etiologic agent of sepsis was isolated. Amongst laboratory tests, thrombocytopenia (platelets < 100.000/mm) was observed on 20.6%, fibrinogen was elevated (> 300 mg/dL) on 81.7%, and the activity of antithrombin was low (< 70%) on 32.5% of patients.The epidemiology of sepsis in this study, in a private hospital of Recife, was no different from what was recently described in Southeast and South of Brazil, United States and Europe.

Verify the association between clinical, epidemiological and laboratorial characteristics with mortality of septic patient in an Intensive Care Unit (ICU) from Pernambuco, northeast of Brazil, to improve the attention for patients with sepse which are in risk of developing organ dysfunction.Case-control study, without intervention, that included adults patients admitted in ICU with sepsis or that developed it during ICU stay.It was included 199 patients. After logistic regression, the length of hospital stay more than 72 hours before admission in ICU, evidence of associated co-morbidities, more than three organ failures, and lactate more than 4 mmol/L were associated with mortality. The SOFA score with more than 12 points was associated with precocity mortality (< 72hours).The septic patients admitted ICU with less than 72h of hospital stay have a better prognosis, and those with a great number of organ failure, and co-morbidities have a superior mortality rate. Between laboratory results, only the high concentration of lactate is associated with mortality.

It is so inconceivable to debug a program without testing it that these two words are used nearly interchangeably. Yet we argue that using the concept of relative correctness we can indeed remove a fault from a program and prove that the fault has been removed, by proving that the new program is more correct than the original. This is a departure from the traditional roles of proving and testing methods, whereby static proof methods are applied to a correct program to prove its correctness, and dynamic testing methods are applied to an incorrect program to expose its faults. © 2016 IEEE.

This empirical study was carried out under operation research project in Jamtara and Dumka district of Jharkhand for achieving the lac cultivation as well as different constraints regarding lac cultivation. The study revealed that West Bengal state stood first in lac cultivation with about 2.814 million while Jharkhand ranked second by 2.647 millions lac cultivators. The availability of lac host plant was observed maximum (9.1 millions) in Jharkhand while Madhya Pradesh was second with 1.9 million host plant and Uttar Pradesh was third with 1.7 million host plant of lac. Two strains of the lac insect are generally recognized in India as 'Rangeeni' and 'Kusumi'. There are two crops in each strain in a year. The strain 'Kusumi' produces crop Aghni in the month of January - February and crop Jethwi in June-July. The Rangeeni strain produces Katki crop in the month of October-November and Baisakhi crop in June-July. The supply of the lac crop from 2000-2001 to 2009-10 revealed that Baisakhi crop produced better among all crop but declining productivity was observed over the years. On export front it was observed that it was maximum during 2000-2001 and it showed a declining trend upto 2006-07 and again it increased during 2007-08 and 2008-09 and the declined in 2009-10. Thailand is main competitor of India in lac export. During 2001-02 the share of lac export of India was 76.71 per cent while Thailand was exporting only 23.29 per cent but during 2009-10 the lac export of India was declined up to 49.75 per cent while Thailand increased the lac export by 50.25 per cent. It was mainly due to less attention paid by the governments on this exportable commodities. The technological, financial and socio-economic constraints were observed as the main cause of low production and productivity of lac in Jharkhand. It is suggested that central as well as state government should provide financial and technological assistance to tribals and economically weaker sections, those are involved in the lac cultivation. The better and remunerative marketing facilities would go a long way in improving the better income and employment to lac cultivators as well as the better foreign currency through export to the government.

Objective: This is an analytic, interventional, cross sectional study to evaluate the risk factors of post-dural (post-lumbar) puncture headache (PDPH) and the validity of the diagnostic criteria for PDPH from the ICHD II.Methods: Six-hundred-and-forty patients (332 non-pregnant women and 308 men) aged 8-65 years underwent spinal anesthesia with Quincke 25G or 27G needles in elective surgery.Results: Forty-eight (7.5%) of the patients developed PDPH. The binary logistic regression analysis identified as risk factors: gender [11.1% female vs. 3.6% male, OR 2.25 (1.07-4.73); p-=-0.03], age [11.0% 31-50 years of age vs. 4.2% others, OR 2.21 (1.12-4.36); p-=-0.02], previous history of PDPH [26.4% positive vs. 6.2% negative, OR 4.30 (1.99-9.31); p-<-0.01] and bevel orientation [16.1% perpendicular vs. 5.7% parallel, OR 2.16 (1.07-4.35); p-=-0.03]. The period of latency between lumbar puncture and headache onset range from 6 to 72 hours and the duration from 3 to 15 days. In 34/48 (71%) patients with PDPH, at least one of the following was present: neck stiffness, tinnitus, hypoacusia, photophobia, or nausea.Conclusion: In conclusion, 14/48 patients (29%) suffered none of the above-mentioned symptoms, indicating that a significant number of patients may suffer from PDPH in the absence of any symptoms apart from the headache itself. This suggests that a further analyses of existing studies should be made to determine if a criteria change may need consideration. © International Headache Society 2012 Reprints and permissions:

Relative correctness is the property of a program to be more-correct than another with respect to a given specification. Whereas the traditional definition of (absolute) correctness divides candidate program into two classes (correct, and incorrect), relative correctness arranges candidate programs on the richer structure of a partial ordering. In other venues we discuss the impact of relative correctness on program derivation, and on program verification. In this paper, we discuss the impact of relative correctness on program testing; specifically, we argue that when we remove a fault from a program, we ought to test the new program for relative correctness over the old program, rather than for absolute correctness. We present analytical arguments to support our position, as well as an empirical argument in the form of a small program whose faults are removed in a stepwise manner as its relative correctness rises with each fault removal until we obtain a correct program. © N.

The increasing criticality of software applications, the increasing size and complexity of such applications, and the increasing reliance of software engineering paradigms on third party software assets combine to place a high premium on the ability to analyze software products to an arbitrary level of thoroughness and precision. Yet despite several decades of research, the goal of analyzing the functional properties of software products to an arbitrary level of thoroughness and precision remains unfulfilled. In this paper, we discuss the use of a relation-theoretic approach inspired from Mills' logic to analyze while loops, and we support our approach by an operational prototype tool. The proposed method and tool have applications in program comprehension, reverse engineering, program verification, software maintenance, and programmer education. © 2012 Springer-Verlag London Limited.

In the same way that natural languages influence and shape the way we think, programming languages have a profound impact on the way a programmer analyzes a problem and formulates its solution in the form of a program. To the extent that a first programming course is likely to determine the student's approach to program design, program analysis, and programming methodology, the choice of the programming language used in the first programming course is likely to be very important. In this paper, we report on a recent survey we conducted on programming language use in US academic institutions, and discuss the significance of our data by comparison with programming language use in industry. © 2015 Vilnius University.
