We evaluated Salmonella enterica serotype Typhi strains isolated from all body sites in Pakistan during 2013–2018. Despite an increase in overall number of localized, extensively drug-resistant Salmonella Typhi in organ infections during 2018, there was no increase in the proportion of such isolates in comparison with non–extensively drug-resistant isolates. 相似文献

BackgroundBody contouring in the postbariatric surgery patient improves quality of life and daily function.ObjectivesTo determine the risk profile of panniculectomy when performed in select patients at the time of bariatric surgery.SettingMetabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) participating centers.MethodsWe examined the MBSAQIP database (2016-2017), in which data on 379,544 bariatric surgeries are reported. Concurrent panniculectomy procedures were identified by Current Procedural Technology (CPT) codes. Patient characteristics and in-hospital as well as 30-day complications were compared between the body contouring group and propensity score-matched bariatric surgery controls.ResultsOne hundred twenty-four patients met inclusion criteria and were matched to 248 controls. An infra-umbilical panniculectomy was performed in the majority of patients (n = 94, 75.8%). Most patients received an open rather than laparoscopic bariatric surgery (n = 87, 70.2%). There were no statistically significant differences between 30-day mortality (1.9%), wound complications (11.5%), readmission (12.5%) and reoperation (5.8%) between the 2 groups (P > .05). Wound complications occurred in 11.5% of patients and were associated with prolonged hospital stay (odds ratio 4.65, 95% confidence interval 1.99–10.86, P < .001) and a body mass index (BMI) > 50 (odds ratio 3.19, 95% confidence interval 1.02–9.96, P = .046).ConclusionIn select patients, panniculectomy at the time of bariatric surgery was not associated with increased in-hospital or 30-day adverse outcomes compared with matched bariatric surgery controls. This procedure may be performed in select patients, with awareness that revision surgery may be needed once weight loss stabilizes. 相似文献

Natural Convection Heat Transfer in a Porous Cavity with Sinusoidal Temperature Distribution Using Cu/Water Nanofluid: Double MRT Lattice Boltzmann Method 下载免费PDF全文
Hasan Sajjadi Amin Amiri Delouei Rasul Mohebbi Mohsen Izadi & Sauro Succi 《Communications In Computational Physics》2021,29(1):292-318
In this study, natural convection flow in a porous cavity with sinusoidal
temperature distribution has been analyzed by a new double multi relaxation time
(MRT) Lattice Boltzmann method (LBM). We consider a copper/water nanofluid filling a porous cavity. For simulating the temperature and flow fields, D2Q5 and D2Q9
lattices are utilized respectively, and the effects of different Darcy numbers (Da) (0.001-0.1) and various Rayleigh numbers (Ra) ($10^3$-$10^5$) for porosity ($ε$) between 0.4 and 0.9
have been considered. Phase deviation ($θ$) changed from 0 to $π$ and the volume fraction
of nanoparticles (Ø) varied from 0 to 6%. The present results show a good agreement
with the previous works, thus confirming the reliability the new numerical method
proposed in this paper. It is indicated that the heat transfer rate increases at increasing
Darcy number, porosity, Rayleigh number, the volume fraction of nanoparticles and
phase deviation. However, the most sensitive parameter is the Rayleigh number. The
maximum Nusselt deviation is 10%, 32% and 33% for Ra=$10^3$, $10^4$ and $10^5$, respectively, with $ε = 0.4$ to $ε = 0.9$. It can be concluded that the effect of Darcy number on
the heat transfer rate increases at increasing Rayleigh number, yielding a maximum
enhancement of the average Nusselt number around 12% and 61% for Ra=$10^3$ and
Ra=$10^5$, respectively. 相似文献

Background: The influence of the contour line alignment software algorithm on the variability of the Heidelberg Retina Tomograph (HRT) parameters remains unclear. Methods: Nine discrete topographic images were acquired with the HRT from the right eye in six healthy, emmetropic subjects. The variability of topometric data obtained from the same topographic image, analyzed within different samples of images, was evaluated. A total of four mean topographic images was computed for each subject from: all nine discrete images (A), the first six of those images (B), the last six of those nine images (C), and the first three combined with the last three images (D). A contour line was computed on the mean topographic image generated from the nine discrete topographic images (A). This contour line was then applied to the three other mean topographic images (B, C, and D), using the contour line alignment in the HRT software. Subsequently, the contour line on the mean topographic images was applied to each of the discrete members of the particular images subsets used to compute the mean topographic image, and the topometric data for these discrete topographic images was computed successively for each subset. Prior to processing each subset, the contour line on the discrete topographic images was deleted. This strategy provided a total of three analyses on each discrete topographic image: as a member of the nine images (mean topographic image A), and as a member of two subsets of images (mean topographic image B, C, and/or D). The coefficient of variation (100×SD/mean) of the topographic parameters within those three analyses was calculated for each discrete topographic image in each subject (intraimage coefficient of variation). In addition, a coefficient of variation between the nine discrete topographic images (interimage coefficient of variation) was calculated. Results: The intraimage and interimage variability for the various topographic parameters ranged between 0.03% and 3.10% and between 0.03% and 24.07% respectively. The intraimage coefficients of variation and interimage coefficients of variation correlated significant (r
2=0.77;P<0.0001). Conclusion: A high intraimage variability, i.e. a high variability in contour line alignment between sequential images, might be an important source of test re-test variability between sequential images. 相似文献

Thirty-eight chronic hepatitis C (CHC) Egyptian patients with persistently elevated serum alanine aminotransferase (ALT) for 6 months were randomly allocated into 2 groups: Group I (19 patients) received 3 million units (MU) of interferon alpha - 2b (Intron-A) subcutaneously thrice weekly for 6 months. In group I, complete response (normalization of ALT by the end of treatment) was achieved in 8 patients (42.1%), partial response (decrease of ALT by at least 50% of the pretreatment values) in 7 patients (36.8%) and no response in 4 (21.1%). Sustained response for 6 months after the end of therapy was attained in 4 of the 8 (50%) complete responders. Thus attaining an overall sustained response in 4 of the 19 patients (21.1%). In group II, spontaneous normalization of ALT was established in 1 patient (5.3%). Repeat liver biopsies in 16 patients of the interferon group, revealed moderate improvement in the degree of lobular inflammation, hepatocyte necrosis and portal inflammation. We conclude from this study that treatment of CHC with 3 MU of IFN-alfa 2b thrice weekly for 6 months is associated with a low response rate (21.1%). To improve the results, escalation of the IFN dose and/or prolongation of the treatment period should be considered. 相似文献

Giving adequate information about febrile convulsion and its prognosis would be helpful in alleviating parental stress, and
would contribute to decrease in the morbidity of febrile convulsion. In this study, the knowledge level of parents on taking
body temperature, and decreasing high fever, their attitudes during febrile convulsion and the impact of febrile convulsion
on parents are evaluated. One hundred seventy-four parents of 132 children with FC were enrolled in the study. Twenty-seven
per cent of parents had no thermometer at home, 32.8% of them did not know how to take a temperature, 72.2% of them did not
know the minimum range of increased body temperature, and 69.5% of them did not know how to decrease the increased body temperature.
Thirty-six percent of parents recognised the convulsions when their children suffered from them, the others assumed the convulsion
were fainting spells (6.9%), near death state (38.5%) and suffocation (18.4%). Thirty-six per cent of parents brought their
children to the hospital without doing anything themselves. Most parents (91.4%) had a fear of a recurrence of febrile convulsion
in their children. Seventy-four per cent of parents complained of insomia, 24.3% parents had dyspeptic symptoms even 14 parents
had weight loss due to dyspepsia. 相似文献

The characteristics of facial nerve electromyography at various levels of neuromuscular blockade are unclear. Partial blockade is well known to facilitate anesthetic safety and management. However, the use of neuromuscular blockage in many skull base procedures is avoided to allow intraoperative facial nerve monitoring.We studied the influence of various levels of neuromuscular blockade on facial nerve stimulation in the New Zealand white rabbit. The facial nerve was exposed in the middle ear of six rabbits. Using electromyographic-type facial nerve monitor, we recorded the facial electromyography signals in these rabbits at increasing levels of vecuronium-induced neuromuscular blockade. All animals demonstrated reliable facial electromyography response at all levels of partial neuromuscular blockade (P < .02). Five of the six animals could be monitored throughout complete blockade. These results clearly demonstrate that rabbit facial electromyography monitoring is possible under neuromuscular blockade. The effect of neuromuscular blockers on facial electromyography monitoring deserves further study, as partial blockade would greatly facilitate the management of anesthesia in otologic, neurotologic, and skull base surgery. 相似文献
