ABSTRACT Turnaround time is an important consideration in surgical pathology. Attempts to shorten the time necessary for making a histopathological slide from the surgical tissue has been tried in various ways since many decades without compromising the quality of it. One amongst such attempt is the introduction of microwave to the field of his totechnology. Microwaves, a form of electromagnetic wave induced heat when applied in histotechnology, reproducibly yields histolologic material of similar or superior quality to that provided by conventional processing methods making it more popular in the recent years. A laboratory microwave offers features like maximum output of 2000-3000 watts, an in built source of adjustable temperature probe, facility for ventilation of hazardous fumes, but is expensive. Considering the usefulness of microwave in histotechnology by reducing the time required for the diagnosis, replacing the conventional equipments of laboratories to microwave guided ones is a remarkable and an acceptable change.

Changes in the field of pathology and resident education necessitate ongoing evaluation of residency training. Evolutionary change is particularly important for surgical pathology rotations, which form the core of anatomic pathology training programs. In the past, we organized this rotation based on subjective insight. When faced with the recent need to restructure the rotation, we strove for a more evidence-based process. Our approach involved 2 primary sources of data. We quantified the number of cases and blocks submitted per case type to estimate workload and surveyed residents about the time required to gross specimens in all organ systems. A multidisciplinary committee including faculty, residents, and staff evaluated the results and used the data to model how various changes to the rotation would affect resident workload, turnaround time, and other variables. Finally, we identified rotation structures that equally distributed work and created a point-based system that capped grossing time for residents of different experience. Following implementation, we retrospectively compared turnaround time and duty hour violations before and after these changes and surveyed residents about their experiences with both systems. We evaluated the accuracy of the point-based system by examining grossing times and comparing them to the assigned point values. We found overall improvement in the rotation following the implementation. As there is essentially no literature on the subject of surgical pathology rotation organization, we hope that our experience will provide a road map to improve pathology resident education at other institutions.

Checklist Implementation

ABSTRACT Objectives An intraoperative consultation (IOC) checklist was developed and implemented aimed at standardizing slide labeling and monitoring metrics central to quality and safety in surgical pathology. Design Data were collected for all IOC cases over a 9-month period. Slide labeling defect rates and IOC turnaround time (TAT) were recorded and compared for the pre- and postimplementation periods. Results In total, 839 IOC cases were analyzed. Preintervention slide labeling showed that 85% of cases contained at least one defect (n = 565). Postintervention data revealed that 27% of cases contained at least one defect (n = 274). The improvement was statistically significant (P < .001). Mean TAT was 21.6 minutes preintervention vs 23.2 minutes postintervention, and the change was insignificant (P = .071). Conclusions The implementation of a standardized IOC reduced slide labeling error. This improvement did not affect mean TAT and may have the increased quality of IOC TAT data reporting. Other metrics affecting patient safety and quality were monitored and standardized.

Abstract Context.—There are multiple elements that can be measured to assess the quality of a surgical pathology laboratory. Overall customer satisfaction is an excellent “global” measure, because it highlights the unique insight of laboratory performance from the users' perspective. Objective.—To measure customer satisfaction with surgical pathology reports. Design.—This study was based on a subscription Q-Tracks study. Voluntary participants were asked to distribute and collect a minimum of 25 surveys per quarter from their clients. Four parameters were graded, which included overall satisfaction, report turnaround time (TAT), completeness, and style on a scale of 1 (poor) to 5 (excellent). Each laboratory submitted quarterly data to the College of American Pathologists, where the data were tabulated and analyzed. Each laboratory could compare their performance in all 4 measures against the entire cohort or a selected subgroup of laboratories. Overall customer satisfaction with surgical pathology reports and 3 subcategories of report TAT, completeness, and style were the main outcome measures. Results.—This study ran during 2004 and 2005, with 41 and 33 participant laboratories, respectively. The median score for overall satisfaction, TAT, completeness, and style were 4.57, 4.31, 4.62, and 4.64 in 2004, and 4.64, 4.56, 4.65, and 4.68 in 2005, respectively. Most laboratories reported results for 4 quarters or fewer. There was no statistically significant change in overall satisfaction over time. Conclusions.—Overall satisfaction scores for surgical pathology reports as well as satisfaction with report TAT, completeness, and style were high. Report TAT received the lowest scores of all parameters.

Here the investigations are done while distillation of ethanol-water mixture for separating ethanol from fermentation process. Focus is to study reduction in time required and hence saving in energy for the distillation process of ethanol-water mixture under the influence of surface-active agents (Surfactants). This novelty is from observation of these surfactants to enhance heat transfer rate because of surface tension reduction in aqueous solutions. SDS (Sodium Dodecyl Sulphate), NH4Cl (Ammonium Chloride) and SLBS (Sodium lauryl benzene sulphonate) surfactants in different concentration are experimented. The concentration of these surfactant is varied from 1700 ppm to 2800 ppm. This range is decided by observing critical micelle concentration of used surfactants. Results showed that time is reduced and hence energy consumption is also reduced. Results shown by NH4Cl are found to be more useful as it is ecofriendly surfactant which is not affecting ethanol-water mixture. Use of ammonium chloride as surfactant in distillation is actually useful to reduce energy without hampering the quality of process is the novelty of this work.

African Breadfruit

The extracted seeds of African breadfruit are identified to be extremely healthy whenever it is correctly processed. Therefore, the aim of the present study was to evaluate the effects of processing methods on the nutritional quality of African breadfruit seed. A qualitative phytochemical analysis including: Alkaloid, Flavonoid, Saponin, Tannin, Anthraquinone, Terpenoids, Steroid, and Cardiac Glycosides for the different fraction of African breadfruit seed was performed using a standard method. The result revealed the presence and greater amount of phytochemical for the raw fraction; seven in eight, six in eight for steamed fraction, and four in eight for boiled and roasted respectively. Anti-nutrient, Proximate, and Mineral Content were also conducted using standard methods. The amino acid composition was determined using High-Performance Liquid Chromatography (HPLC). The results of the present study revealed that anti-nutrients including Phytate, Tannins, and Oxalate were significantly p<0.05 reduced in the boiled fraction 5.47±0.15, 3.42±0.02 and 6.89±0.05, and highest in the raw fraction 7.77±0.01, 5.09±0.03 and 9.34±0.14. The proximate composition including; percentage crude fat, Ash, Carbohydrate, Fatty acid, and Energy value were significantly lower p<0.05 in the boiled fraction relative to the other fractions. Mineral contents; calcium, magnesium, sodium, potassium, and phosphorus were also significantly p<0.05 elevated in the boiled fraction relative to the raw, steamed, and roasted fraction. The amino acid composition was highest in the roasted and boiled fraction 57.350 and 56.978, and lowest in the steamed and raw fraction 35.754 and 28.748 respectively. Therefore, boiling (cooking) is encouraged for the preparation of African breadfruit seed.

Highlights 3D printing of MXene frames with tunable electromagnetic interference shielding efficiency is demonstrated. Highly conductive MXene frames are reinforced by cross-linking with aluminum ions. Electromagnetic wave is visualized by electromagnetic-thermochromic MXene patterns. Abstract The highly integrated and miniaturized next-generation electronic products call for high-performance electromagnetic interference (EMI) shielding materials to assure the normal operation of their closely assembled components. However, the most current techniques are not adequate for the fabrication of shielding materials with programmable structure and controllable shielding efficiency. Herein, we demonstrate the direct ink writing of robust and highly conductive Ti3C2Tx MXene frames with customizable structures by using MXene/AlOOH inks for tunable EMI shielding and electromagnetic wave-induced thermochromism applications. The as-printed frames are reinforced by immersing in AlCl3/HCl solution to remove the electrically insulating AlOOH nanoparticles, as well as cross-link the MXene sheets and fuse the filament interfaces with aluminum ions. After freeze-drying, the resultant robust and porous MXene frames exhibit tunable EMI shielding efficiencies in the range of 25–80 dB with the highest electrical conductivity of 5323 S m−1. Furthermore, an electromagnetic wave-induced thermochromic MXene pattern is assembled by coating and curing with thermochromic polydimethylsiloxane on a printed MXene pattern, and its color can be changed from blue to red under the high-intensity electromagnetic irradiation. This work demonstrates a direct ink printing of customizable EMI frames and patterns for tuning EMI shielding efficiency and visualizing electromagnetic waves.

AbstractImproving public awareness through education has been recognized widely as a basis for reducing the risk of disasters. Some of the first disaster just-in-time (JIT) education modules were built within 3–6 days after the south Asia tsunami, Hurricane Katrina, and the Bam, Pakistan, and Indonesia earthquakes through a Supercourse. Web monitoring showed that visitors represented a wide spectrum of disciplines and educational levels from 120 developed and developing countries. Building disaster networks using an educational strategy seizes the opportunity of increased public interest to teach and find national and global expertise in hazard and risk information. To be effective, an expert network and a template for the delivery of JIT education must be prepared before an event occurs, focusing on developing core materials that could be customized rapidly, and then be based on the information received from a recent disaster. The recyclable process of the materials would help to improve the quality of the teaching, and decrease the time required for preparation. The core materials can be prepared for disasters resulting from events such as earthquakes, hurricanes, tsunamis, floods, and bioterrorism.

Abstract Context.—Good communication of pathologic characteristics of a malignancy is crucial to therapy choices and accurate prognostication. The information must be easily retrieved from a surgical pathology report. Objectives.—To evaluate, first in 1999, the quality of surgical pathology reports for segmental breast resections for cancer in Quebec hospitals. Subsequently, to reevaluate, in 2003, the same indicators to determine if the first surveillance, with feedback, was associated with an improvement in the quality of the reports. Design.—All Quebec hospitals performing the preset number of 20 or more segmental breast resections for cancer in 1999 and 2003 participated. A committee of pathologists, after review of the literature, chose 7 diagnostic elements deemed vital to a surgical pathology report for conservative breast cancer surgery. Medical archivists in each institution were instructed on how to retrieve the data. The main outcome measure was the presence or absence of the diagnostic information clearly presented on the surgical pathology report. Results.—Fifty-one hospitals participated in 1999 and 50 in 2003. Overall, conformity improved from 85.0% in 1999 for the first evaluation to 92.5% in 2003 for the second evaluation (P &lt; .001). Six of the 7 indicators showed an improvement in the level of conformity between the first and second evaluations. Conformity was weakest for recording the distance between the tumor and the resection margin (68.2%) and vascular/lymphatic invasion (61.4%) in 1999. Conclusions.—Surveillance of quality of surgical pathology reports, with feedback, is significantly associated with an improvement in the quality of reports.

Background: The development of digital imaging systems for radiology in combination with the possibility to transfer large quantities of data over the Internet has increased the interest in teleradiology. Transferring nighttime examinations to an evaluation center in a daytime zone may provide improved patient security, better working hours for radiologists, and reduced costs for emergency radiological services. Purpose: To evaluate the time required for transferring radiological information from Uppsala (Sweden) to Sydney (Australia). Material and Methods: A radiologist in Sydney reported on radiological examinations performed in Uppsala. The time required for downloading 75 examinations and returning 24 reports was registered. Results: Downloading was completed in <60 min for all conventional radiological examinations, but only 44% of computed tomography (CT) examinations with >65 images. Reports were completed in <10 min. Turnaround time was directly related to the time required for downloading the images. The Sydney report was available in Uppsala within 30 min of the in-house report in 79% of examinations. Conclusion: The main challenge for emergency teleradiology is the time required for downloading large volumes of data over the Internet.
