Backgrounds/Aims: Postoperative pancreatic fistula is the key worry in the ongoing debate about the safety and effectiveness of total laparoscopic pancreaticoduodenectomy (TLPD). Laparoscopic-assisted pancreaticoduodenectomy (LAPD), a hybrid approach combining laparoscopic resection and anastomosis with a small incision, is an alternative to TLPD. This study compares the short-term outcomes and oncological efficacy of LAPD vs. open pancreaticoduodenectomy (OPD). Methods: A retrospective analysis of data of all patients who underwent LAPD or OPD for periampullary carcinoma at a tertiary care center in Northeast India from July 2019 to August 2023 was done. A total of 30 LAPDs and 30 OPDs were compared after 1:1 propensity score matching. Demographic data, intraoperative and postoperative data (30 days), and pathological data were compared. Results: The study included a total of 93 patients, 30 underwent LAPD and 62 underwent OPD. After propensity score matching, the matched cohort included 30 patients in both groups. The LAPD presented several advantages over the OPD group, including a shorter incision length, reduced postoperative pain, earlier initiation of oral feeding, and shorter hospital stays. LAPD was not found to be inferior to OPD in terms of pancreatic fistula incidence (Grade B, 30.0% vs. 33.3%), achieving R0 resection (100% vs. 93.3%), and the number of lymph nodes harvested (12 vs. 14, p = 0.620). No significant differences in blood loss, short-term complications, pathological outcomes, readmissions, and early (30-day) mortality were observed between the two groups. Conclusions: LAPD has comparable safety, technical feasibility, and short-term oncological efficacy.

Bandari Mahesh,Abhishek Pathak,Rameshwar Nath Chaurasia,Anand Kumar,Varun Kumar Singh 대한신경집중치료학회 2021 대한신경집중치료학회지 Vol.14 No.2

Background: Guillain-Barré syndrome (GBS) is an immune-mediated inflammatory polyneuropathy characterized by acute flaccid paralysis. Elevated creatine kinase (CK) levels in GBS have been reported to be transient, and levels vary from mild to severe. Herein, we report a case of GBS with elevated CK mimicking acute myositis.Case Report: A 48-year-old man presented with pure motor flaccid quadriparesis. Power was 2/5 with hypotonia and areflexia in all four limbs. A nerve conduction study revealed reduced compound muscle action potential in all recorded motor nerves. Serum CK was 2,334 U/L. The patient’s symptoms progressed despite intravenous methylprednisolone administration. Cerebrospinal fluid (day 8) revealed albuminocytological dissociation, and electromyography (day 21) revealed spontaneous activity with neurogenic motor unit action potential suggestive of acute motor axonal neuropathy variant of GBS.Conclusion: In a patient with elevated CK and ascending paralysis, differential diagnosis of GBS should be considered and cerebrospinal fluid study and electromyography should aid in confirming the diagnosis.

Synthesis and Characterization of Sulfonated Poly(arylene ether) Polyimide Multiblock Copolymers for Proton Exchange Membranes

Lee, Hae-Seung,Roy Abhishek,Badami Anand S.,McGrath James E. The Polymer Society of Korea 2007 Macromolecular Research Vol.15 No.2

Novel multiblock copolymers, based on segmented sulfonated hydrophilic-hydrophobic blocks, were synthesized and investigated for their application as proton exchange membranes. A series of segmented sulfonated poly(arylene ether sulfone)-b-polyimide multiblock copolymers, with various block lengths, were synthesized via the coupling reaction between the terminal amine moieties on the hydrophilic blocks and naphthalene anhydride functionalized hydrophobic blocks. Successful imidization reactions required a mixed solvent system, comprised of NMP and m-cresol, in the presence of catalysts. Proton conductivity measurements revealed that the proton conductivity improved with increasing hydrophilic and hydrophobic block lengths. The morphological structure of the multiblock copolymers was investigated using tapping mode atomic force microscopy (TM-AFM). The AFM images of the copolymers demonstrated well-defined nanophase separated morphologies, with the changes in the block length having a pronounced effect on the phase separated morphologies of the system. The self diffusion coefficient of water, as measured by $^1H$ NMR, provided a better understanding of the transport process. Thus, the block copolymers showed higher values than Nafion, and comparable proton conductivities in liquid water, as well as under partially hydrated conditions at $80^{\circ}C$. The new materials are strong candidates for use in PEM systems.

Internet Of Things As A Solution Enabler In Health Sector

Yatin Jog,Apurva Sharma,Kalyani Mhatre,Anand Abhishek 보안공학연구지원센터 2015 International Journal of Bio-Science and Bio-Techn Vol.7 No.2

India is a country where vast medical needs are not met. Internet of Things (IoT) has created a new horizon in health care sector which specifically aims at connecting the world via smart objects. IoT enabled devices are used in various industries such as Envi-ronmental Monitoring, Building and Home Automation, Medical and Healthcare Systems, Infrastructure Management, Transport Systems, Energy Management, Industrial Applica-tions, etc. Healthcare industry is one of the biggest industries that provides health care products and incorporates the delivery of services to patients. These services are supported by electronic processs called as E-health. Using IoT devices remote health monitoring and notification can be done easily as well as quickly in case of emergency. Smart TV as a platform for E-Health Services can also be called as “Health-TV” which is one of the technology that provides IoT based e-Health Solutions to the patients. ICT in-dustry mainly focuses on the easy access of remote health services such as medication reminder, health monitoring and health coaching at home. It also helps in independent living style for the patient like senior citizen, managing and accessing health services in a specific condition from home via Health TV. “Smart infusion pumps” is another technol-ogy which is used for treating patients more carefully and accurately. It collects data and then aggregates in a database which contains the records of the administration in the central server. They are basically network devices which connect hospitals and clinics through wireless local area network.”Smart-o-meter” is a Web-based patient-centered decision support system for BP control using an iterative, user-centered design process so that it meets standards of feasibility and acceptability for patient navigators and partici-pants. The outcome or suggestion of this intensive research:  The government should implement the health care technological solutions, as pri-vate organizations can’t reach maximum masses of India.  A shift from traditional methods to the conventional methods of health care prac-tices in India is required so as to build a better environment for the people to live in.  As many Indians are still hesitant of relying on internet based technology, espe-cially IoT (fact from our survey over respondent in city PUNE, INDIA), a proper aware-ness session and demo session should be conducted in leading hospitals and institutes.

Gautam Alok Sagar,Sanjeev Kumar,Sneha Gautam,Aryan Anand,Ranjit Kumar,Abhishek Joshi,Kuldeep Bauddh,Karan Singh 한국기상학회 2021 Asia-Pacific Journal of Atmospheric Sciences Vol.57 No.4

The present paper designed to understand the variations in the atmospheric pollutants viz. PM10, PM2.5, SO2, NO2, and CO during the COVID-19 pandemic over eight most polluted Indian cities (Mumbai, Delhi, Bangalore, Hyderabad, Lucknow, Chandigarh, Kolkata, and Ahmedabad). A significant reduction in the PM2.5 (63%), PM10 (56%), NO2 (50%), SO2 (9%), and CO (59%) were observed over Major Dhyan Chand Stadium. At Chhatrapati Shivaji International Airport, a decline of 44% in PM2.5 and 50% in PM10 was seen just a week during the initial phase of the lockdown. Gaseous pollutants (NO2, SO2 & CO) dropped up-to 36, 16, and 41%, respectively. The Air Quality Index (AQI) shows a dramatic change from 7% to 67% during observation at Chandigarh and Ballygunge during the inspection. Whereas, Ahmedabad, Worli, Income Tax Office, Talkatora, Lalbagh, and Ballygaunge have showed a significant change in AQI from 25.76% to 68.55%. However, Zoo Park, CST, Central School, and Victoria show relatively low variation in AQI in the range of 3.0% to 14.50% as compare to 2019 after lockdown. Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) analysis suggested that long range transportation of pollutants were also a part and parcel contributing to changes in AQI which were majorly coming from the regions of Iran, Afghanistan, Saudi Arabia, as well as a regional grant from Indian Gangatic plains and Delhi Non-capital region.

Background/Aims The prevalence of irritable bowel syndrome (IBS) varies from 4% to 20% in different Asian nations. Prevalence of IBS in native North Indian community is not known. Methods Between November 2008 to December 2009, we estimated the prevalence of IBS in a rural community of Ballabgarh block, located in Haryana state. A structured questionnaire based on Rome Ⅲ module was used to collect symptoms related to IBS from all the participants in a door to door survey. A Rome Ⅲ criterion was used for diagnosis of IBS. IBS was further classified based on predominance of symptoms as constipation predominant, diarrhea predominant, mixed and unspecified based on Rome Ⅲ module. Results There were 4,767 participants (mean age 34.6±10.8, males 50%). Overall, 555 (11.6%; 95% CI, 10.7-12.5) had constipation, 542 (11.4%; 95% CI, 10.5-12.3) diarrhea and 823 (17.3%; 95% CI, 16.2-18.4) abdominal pain. The overall prevalence of IBS was 4% (95% CI, 3.5-4.6). The prevalence of constipation predominant IBS was 0.3% (95% CI, 0.16-0.49), diarrhea predominant IBS 1.5% (95% CI, 1.18-1.90), mixed IBS 1.7% (95% CI, 1.35-2.11) and unsubtyped IBS 0.5% (95% CI, 0.32-0.75). The prevalence of IBS was significantly higher in females compared with males (4.8% vs 3.2%, P=0.008). However, there was no significant difference between males and females in the prevalence of different subtypes of IBS. The prevalence increased with age. Conclusions The prevalence of IBS in a North Indian community is 4%. IBS poses a significant burden on the rural adults. (J Neurogastroenterol Motil 2011;17:82-87)

Bharat Bhushan Jindal,Dhirendra Singhal,Sanjay Sharma,Aniket Yadav,Shubham Shekhar,Abhishek Anand 사단법인 한국계산역학회 2017 Computers and Concrete, An International Journal Vol.20 No.6

This paper presents the experimental investigations on the compressive strength and permeation properties of geopolymer concrete prepared with low calcium fly ash as the primary binder activated with different percentage of Alccofine. The durability aspect was investigated by performing permeable voids and water absorption tests since permeability directly influences the durability properties. The test results show that Alccofine significantly improves the compressive strength and reduces the water permeability thus enhances the durability of geopolymer concrete at ambient curing regime which encourages the use of geopolymer concrete at ambient curing condition thus promising its use in general construction also.
