RESUMO

Background: Laparoscopic Heller myotomy (LHM) can be performed by blunt dissection technique (BDT). Only a few studies have assessed long-term outcomes and relief of dysphagia following LHM. The study reviews our long-term experience following LHM by BDT. Methods: This retrospective study was analysed from a prospectively maintained database (from 2013 to 2021) of a single unit of the Department of Gastrointestinal Surgery at G. B. Pant Institute of Postgraduate Medical Education and Research, New Delhi. The myotomy was performed by BDT in all patients. A fundoplication was added in selected patients. Post-operative Eckardt score >3 was considered treatment failure. Results: A total of 100 patients underwent surgery during the study period. Of them, 66 patients underwent LHM, 27 underwent LHM with Dor fundoplication and 7 underwent LHM with Toupet fundoplication. The median length of myotomy was 7 cm. The mean operative time was 77 ± 29.27 min and the mean blood loss of 28.05 ± 16.06 ml. Five patients had intraoperative oesophageal perforation. The median length of hospital stay was 2 days. There was no hospital mortality. The post-operative integrated relaxation pressure (IRP) was significantly lower than the mean pre-operative IRP (9.78 vs. 24.77). Eleven patients developed treatment failure, of which ten patients presented with recurrence of dysphagia. There was no difference in symptom-free survival amongst various types of achalasia cardia (P = 0.816). Conclusion: LHM performed by BDT has a 90% success rate. Complication using this technique is rare, and recurrence post-surgery can be managed with endoscopic dilatation.

RESUMO

Enzymes play vital roles in all organisms. The enzymatic process is progressively at its peak, mainly for producing biochemical products with a higher value. The immobilization of enzymes can sometimes tremendously improve the outcome of biocatalytic processes, making the product(s) relatively pure and economical. Carrier-free immobilized enzymes can increase the yield of the product and the stability of the enzyme in biocatalysis. Immobilized enzymes are easier to purify. Due to these varied advantages, researchers are tempted to explore carrier-free methods used for the immobilization of enzymes. In this review article, we have discussed various aspects of enzyme immobilization, approaches followed to design a process used for immobilization of an enzyme and the advantages and disadvantages of various common processes used for enzyme immobilization.

RESUMO

The coronavirus disease 2019 crisis has forced the world to integrate telemedicine into health delivery systems in an unprecedented way. To deliver essential care, lawmakers, physicians, patients, payers, and health systems have all adopted telemedicine and redesigned delivery processes with accelerated speed and coordination in a fragmented way without a long-term vision or uniformed standards. There is an opportunity to learn from the experiences gained by this pandemic to help shape a better health-care system that standardizes telemedicine to optimize the overall efficiency of remote health-care delivery. This collaboration focuses on four pillars of telemedicine that will serve as a framework to enable a uniformed, standardized process that allows for remote data capture and quality, aiming to improve ongoing management outside the hospital. In this collaboration, we recommend learning from this experience by proposing a telemedicine framework built on the following four pillars-patient safety and confidentiality; metrics, analytics, and reform; recording of audio-visual data as a health record; and reimbursement and accountability.

RESUMO

BACKGROUND AND OBJECTIVES: Published literature is silent about the gender gap in tuberculosis (TB) among adolescent (10-19 years) population despite extensive information on increased susceptibility of the male gender after 20 years. We analyzed the data from 1113 adolescent microbiologically confirmed TB cases using cartridge-based nucleic acid amplification test (CBNAAT) in 2019 in the State of Himachal Pradesh (HP), India. MATERIALS AND METHODS: The data generated by 39 CBNAAT sites in HP were analyzed with an objective to describe the gender gap in TB among adolescents. RESULTS: Among 983 patients with pulmonary TB (PTB), the male: female ratio was 1:1.5 (P = 0.0001), whereas in 130 patients with extra PTB (EPTB), the male: female ratio was 1:1.8 (P = 0.0001). This male: female ratio was seen to reverse after 20 years for PTB, and but it persisted till 40 years for EPTB. Two main forms of TB that were significantly high in females during adolescence were PTB and lymph node TB (P = 0.0001). INTERPRETATION AND CONCLUSIONS: Significant gender difference with female susceptibility was seen for TB among adolescents, a fact that needs more research. Adolescent TB is a neglected area with little published data driven mainly by the fact that most countries report their TB population above and below 15 years, dividing the adolescent population into two halves. The world needs to acknowledge adolescents (10-19 years) as a separate important group for reporting TB statistics.

RESUMO

Around 200 different lipopeptides (LPs) have been identified to date, most of which are produced via Bacillus and Pseudomonas species. The clinical nature of the lipopeptide (LP) has led to a big surge in its research. They show antimicrobial and antitumor activities due to which mass-scale production and purification of LPs are beneficial. Response surface methodology (RSM) approach has emerged as an alternative in the field of computational biology for optimizing the reaction parameters using statistical models. In the present study, Pseudomonas sp. strain OXDC12 was used for production and partial purification of LPs using Thin Layer Chromatography (TLC). The main goal of the study was to increase the overall yield of LPs by optimizing the different variables in the fermentation broth. This was achieved using a combination of one factor at a time (OFAT) and response surface methodology (RSM) approaches. OFAT technique was used to optimize the necessary parameters and was followed by the creation of statistical models (RSM) to optimize the remaining variables. Maximum mycelial growth inhibition (%) against the fungus Mucor sp. was 61.3% for LP. Overall, the combination of both OFAT and RSM helped in increasing the LPs yield by 3 folds from 367mg/L to 1169mg/L.

RESUMO

Human microbiota comprises of trillions of microbes which have evolved with and continued to live on/ within their human hosts. Different environmental factors and diet have a large impact upon human microbiota population. These microorganisms live in synergy with their hosts and are beneficial to the host in many different ways. Many microorganisms help to fight against human diseases. Cancer is one such diseases which effects a large human population often leading to death. Cancer is also one of the most fatal human diseases killing millions of people world-wide every year. Though many treatment procedures are available but none is 100 % effective in curing cancer. In this review, we seek to understand the role of human microbiota in cancer treatment. Lipopeptide(s) (LPs) produced by different microorganisms can act as efficient drug(s) against cancer. LPs are low molecular weight lipo-proteins that are also known for their anti-cancer activities. As human microbiota belongs to an environment within the host body, a drug prepared using these microorganisms will be easily accepted by the body. This novel approach of using LPs produced by human microbiota can be considered for the much needed change in cancer treatment. Therefore, it is proposed that research should focus on the host-microbe interaction which could pave the way in understanding role played by these microorganisms in cancer treatment.
