The emergence of smartphone-based imaging devices has been a boon in the field of ophthalmology, especially in obtaining high-quality ocular images. They can be specialized and utilized for imaging-specific regions of the eye. Among the multitude of applications of smartphone-based imaging, one of the upcoming major use is to image the microbiological world. Previous few reports have described attaching magnifying lenses of various types to the smartphone camera and transforming it into a microscope for imaging fungal hyphae and ocular surface parasites. We describe a novel technique of attaching the smartphone-based intraocular lens microscope (IOLSCOPE) to the slit lamp, thereby utilizing the slit lamp joystick for moving the smartphone over the concerned slide specimen to make it steady and obtain images of high resolution. This innovative do-it-yourself novel modification is especially useful in peripheral centers, vision centers, and local clinics for immediate screening and identification of microbial pathogens such as fungi and ocular surface parasites. 相似文献

Introduction
Current National Comprehensive Cancer Network guidelines recommend neoadjuvant therapy for borderline resectable pancreatic adenocarcinoma to increase the likelihood of achieving R0 resection. A consensus has not been reached on the degree of venous involvement that constitutes borderline resectability. This study compares the outcome of patients who underwent pancreaticoduodenectomy with or without vein resection without neoadjuvant therapy.Methods
A multi-institutional database of patients who underwent pancreaticoduodenectomy was reviewed. Patients who required vein resection due to gross vein involvement by tumor were compared to those without evidence of vein involvement.Results
Of 492 patients undergoing pancreaticoduodenectomy, 70 (14 %) had vein resection and 422 (86 %) did not. There was no difference in R0 resection (66 vs. 75 %, p?=?NS). On multivariate analysis, vein involvement was not predictive of disease-free or overall survival.Conclusion
This is the largest modern series examining patients with or without isolated vein involvement by pancreas cancer, none of whom received neoadjuvant therapy. Oncological outcome was not different between the two groups. These data suggest that up-front surgical resection is an appropriate option and call into question the inclusion of isolated vein involvement in the definition of “borderline resectable disease.” 相似文献6.

Background
This study utilized a multi-institutional database to evaluate risk factors for readmission in patients undergoing curative gastrectomy for gastric adenocarcinoma with the intent of describing both perioperative risk factors and the relationship of readmission to survival.Methods
Patients who underwent curative resection of gastric adenocarcinoma from 2000 to 2012 from seven academic institutions of the US Gastric Cancer Collaborative were analyzed. In-hospital deaths and palliative surgeries were excluded, and readmission was defined as within 30 days of discharge. Univariate and multivariable logistic regression analyses were employed and survival analysis conducted.Results
Of the 855 patients, 121 patients (14.2 %) were readmitted. Univariate analysis identified advanced age (p?<?0.0128), American Society of Anesthesiology status ≥3 (p?=?0.0045), preexisting cardiac disease (p?<?0.0001), hypertension (p?=?0.0142), history of smoking (p?=?0.0254), increased preoperative blood urea nitrogen (BUN; p?=?0.0426), concomitant pancreatectomy (p?=?0.0056), increased operation time (p?=?0.0384), estimated blood loss (p?=?0.0196), 25th percentile length of stay (<7 days, p?=?0.0166), 75th percentile length of stay (>12 days, p?=?0.0256), postoperative complication (p?<?0.0001), and total gastrectomy (p?=?0.0167) as risk factors for readmission. Multivariable analysis identified cardiac disease (odds ratio (OR) 2.4, 95 % confidence interval (CI) 1.6–3.3, p?<?0.0001), postoperative complication (OR 2.3, 95 % CI 1.6–5.4, p?<?0.0001), and pancreatectomy (OR 2.2, 95 % CI 1.1–4.1, p?=?0.0202) as independent risk factors for readmission. There was an association of decreased overall median survival in readmitted patients (39 months for readmitted vs. 103 months for non-readmitted). This was due to decreased survival in readmitted stage 1 (p?=?0.0039), while there was no difference in survival for other stages. Stage I readmitted patients had a higher incidence of cardiac disease than stage I non-readmitted patients (58 vs. 24 %, respectively, p?=?0.0002).Conclusions
Within this multi-institutional study investigating readmission in patients undergoing curative resection for gastric cancer, cardiac disease, postoperative complication, and concomitant pancreatectomy were identified as significant risk factors for readmission. Readmission was associated with decreased overall median survival, but on further analysis, this was driven by differences in survival for stage I disease only.8.

The antidyslipidemic effect of the ethanolic extract of Dysoxylum binectariferum stem bark and its major active constituent rohitukine was evaluated in a high fat diet (HFD)-fed dyslipidemic rat model. Chronic feeding of ethanolic extract (200 mg/kg) in HFD-fed rats showed significant lipid lowering activity. The bioassay guided fractionation of ethanolic extract resulted in the identification of known alkaloid rohitukine as major active constituent. Rohitukine (50 mg/kg) significantly decreased the plasma levels of total cholesterol (24 %), phospholipids (25 %), triglycerides (27 %), very low density lipoprotein (27 %) and low density lipoprotein (32 %) accompanied with an increase in high density lipoprotein (21 %). The present study demonstrated that ethanolic extract of Dysoxylum binectariferum stem bark and its major constituent rohitukine both have antidyslipidemic as well as antioxidant potentials. The antidyslipidemic activity of rohitukine can be correlated to its effect on enzymes involved in lipid metabolism. 相似文献

Background
Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract. Overall surgical experience with minimally invasive surgery (MIS) has increased; however, published reports on MIS resection of GIST are limited to small, single-institution experiences.Methods
A total of 397 patients who underwent open surgery (n = 230) or MIS (n = 167) for a gastric GIST between 1998 and 2012 were identified from a multicenter database. The impact of MIS approach on recurrence and survival was analyzed using propensity-score matching by comparing clinicopathologic factors between patients who underwent MIS versus open resection.Results
There were 19 conversions (10 %) to open; the most common reasons for conversion were tumor more extensive than anticipated (26 %) and unclear anatomy (21 %). On multivariate analysis, smaller tumor size and higher body mass index (BMI) were associated with receipt of MIS. In the propensity-matched cohort (n = 248), MIS resection was associated with decreased length of stay (MIS, 3 days vs open, 8 days) and fewer ≥ grade 3 complications (MIS, 3 % vs open, 14 %) compared with open surgery. High rates of R0 resection and low rates of tumor rupture were seen in both groups. After propensity-score matching, there was no difference in recurrence-free or overall survival comparing the MIS and the open group (both p > 0.05).Conclusions
An MIS approach for gastric GIST was associated with low morbidity and a high rate of R0 resection. The long-term oncological outcome following MIS was excellent, and therefore the MIS approach should be considered the preferred approach for gastric GIST in well-selected patients. 相似文献10.

A simple, rapid and economical method was developed and validated for the determination of metamitron using UV detector with RP-HPLC. Study of metamitron in soil was carried out. The compound was extracted from soil by methanol and clean-up was done on C-18 SPE column. Recovery ranged from 90.75 % to 94.05 % within 0.1–2.0 μg g?1 and RSD 1.80 %. Retention time was 3.8 min and limit of detection and limit of quantification were 0.001 and 0.008 μg g?1. The results indicated that the reported method could meet the requirement for the analysis of metamitron in trace amounts. 相似文献
