Virtual thanks giving to a cadaver by medical students exposed to learning anatomy before and amidst COVID-19 pandemic.

PURPOSE: Due to COVID-19 pandemic, Thanks giving ceremony to cadaver was different this year in two ways: the students were partially exposed to cadaveric dissections (for 7 months) and later learned Anatomy via online classes due to lockdown (for 5 months) and secondly it was not feasible to gather for the ceremony so virtual platform was preferred. The purpose of this study was to discern the gratitude for cadaver and to recognize the importance of cadaveric dissection from the reflection of students who experienced hybrid anatomy learning amidst COVID-19. METHODS: The study was conducted on 48 first year medical students who were admitted to the college in August 2019 and were willing to participate. An online invitation was sent to students to participate in virtual thanks giving to cadaver ceremony on the last day of their anatomy class (August 2020). RESULTS: Though the students partially studied gross anatomy with the aid of dissections on the cadaver; however, they expressed respect and gratitude to the silent mentor in the form of a card, poem, drawing or paragraph and shared it via google classroom platform. The students wished if they could continue their anatomy course in dissection hall as paused due to COVID-19 pandemic. CONCLUSIONS: Reflection of these students may mark impact on future anatomy students who may or may not get the chance for dissections. The thanks-giving gesture will also help to bind medical science and humanity especially during the crisis of pandemic.

Anatomy of peripancreatic arteries and pancreaticoduodenal arterial arcades in the human pancreas: a cadaveric study.

INTRODUCTION: The purpose of this work was to evaluate the arteries supplying the pancreaticoduodenal (PD) complex. MATERIALS AND METHODS: The study was conducted on 15 fresh enbloc pancreatic specimens by latex injection method which enabled the visualization of the peripancreatic arteries and their minute branches. RESULTS: The gastroduodenal (GDA), anterior superior pancreaticoduodenal (ASPD), and anterior inferior pancreaticoduodenal (AIPD) artery was found in all the cases, whereas the posterior superior pancreaticoduodenal (PSPD) and posterior inferior pancreaticoduodenal (PIPD) artery was present in 93.34% cases. The ASPD artery originated from GDA in all the cases. Two types of variations were observed in the origin of PSPD artery and four types each in the origin of AIPD and PIPD artery. Anatomical and numerical variations were observed in both anterior and posterior arches, posterior arch being absent in 20% cases. CONCLUSIONS: In the present study, an attempt was made to systematically describe the individual arterial configurations of the PD complex. The information provided here has important implications for preoperative planning of technically challenging surgeries and interventions around the pancreatic head.

Anatomy education of medical and dental students during COVID-19 pandemic: a reality check.

PURPOSE: During this forced down-time of COVID-19 pandemic, shift to virtual anatomy education is the solitary solution to support the learning of students. The purpose of this study was to understand the visible and invisible potential challenges being faced by the 1st year medical and dental students while attending digital anatomy classes. METHODS: The present study was conducted on 81st year medical and dental students who were admitted to their respective college in August 2019 and were willing to participate in the study. A multiple choice close-ended questionnaire regarding their opinion on virtual classes was designed and feedback was taken from the students. RESULTS: Majority (65%) of the students agreed that they missed their traditional anatomy learning i.e., dissection courses, face to face lectures and interaction with mentors. The students strongly felt the lack of confidence and difficulty in the topics completed without dissections, models, microscopic slides and other modalities. 83% felt lack of proper gadgets, high-band width and strong internet connections, a potential barrier in their digital learning. Lack of self-motivation was felt by 69% students. CONCLUSIONS: The current situation of anatomy education is not intentional, and is not the long term silver bullet solution for a visual subject like anatomy. Though learners face a lot of challenges, however, a shift to online must be supported at this time of health crisis. As the digital learning may go for indefinite period, the feedback of students may be helpful for relevant and timely modifications in digital anatomy education.

Comparative study of spironolactone and eplerenone in management of ascites in patients of cirrhosis of liver.

INTRODUCTION: The present study was conducted to compare the efficacy and side effects of Spironolactone and Eplerenone in management of ascites due to liver cirrhosis. MATERIALS AND METHODS: 105 patients of ascites with liver cirrhosis were randomized into three groups of 35 patients each. Group I was given Spironolactone 100 mg, group II was given Eplerenone 100 mg and group III was given Eplerenone 50 mg. All patients were put on salt-restricted diet (less than or equal to 2 g of sodium) and no loop diuretics were used. Patients were followed after 7 days from the baseline and then biweekly for the period of three months and serial measurements of weight, abdominal girth and incidence of side effects especially gynecomastia, mastalgia, hyperkalemia were recorded. Results were compared. Patients having Child-Turcotte-Pugh score-C, massive ascites, hepatic encephalopathy, Hepatorenal syndrome and ascites due to cardiac, renal, malignant causes were excluded. OBSERVATIONS: Difference in mean weight reduction was non significant (P = 0.964) in group I and group II whereas the difference was significant when comparison was made between Group I and III; and Group II and III (P = <0.001, <0.001, respectively). In group I, the incidence of gynecomastia was 14.28% whereas in group II and group III no case of gynecomastia was observed (P <0.001, <0.001). Hyperkalemia was present in one patient (2.8%) in group I whereas no patient developed hyperkalemia in group II and group III (P = >0.05, >0.05). CONCLUSION: Eplerenone and spironolactone are equally effective in management of ascites due to liver cirrhosis but side effect profile of eplerenone scores over Spironolactone.

Detection of cancer antigens (CA-125) using gold nano particles on interdigitated electrode-based microfluidic biosensor.

Integrating microfluidics with biosensors is of great research interest with the increasing trend of lab-on-the chip and point-of-care devices. Though there have been numerous studies performed relating microfluidics to the biosensing mechanisms, the study of the sensitivity variation due to microfluidic flow is very much limited. In this paper, the sensitivity of interdigitated electrodes was evaluated at the static drop condition and the microfluidic flow condition. In addition, this study demonstrates the use of gold nanoparticles to enhance the sensor signal response and provides experimental results of the capacitance difference during cancer antigen-125 (CA-125) antigen-antibody conjugation at multiple concentrations of CA-125 antigens. The experimental results also provide evidence of disease-specific detection of CA-125 antigen at multiple concentrations with the increase in capacitive signal response proportional to the concentration of the CA-125 antigens. The capacitive signal response of antigen-antibody conjugation on interdigitate electrodes has been enhanced by approximately 2.8 times (from 260.80 to 736.33 pF at 20 kHz frequency) in static drop condition and approximately 2.5 times (from 205.85 to 518.48 pF at 20 kHz frequency) in microfluidic flow condition with gold nanoparticle-coating. The capacitive signal response is observed to decrease at microfluidic flow condition at both plain interdigitated electrodes (from 260.80 to 205.85 pF at 20 kHz frequency) and gold nano particle coated interdigitated electrodes (from 736.33 to 518.48 pF at 20 kHz frequency), due to the strong shear effect compared to static drop condition. However, the microfluidic channel in the biosensor has the potential to increase the signal to noise ratio due to plasma separation from the whole blood and lead to the increase concentration of the biomarkers in the blood volume for sensing.
