The idea of a neuromuscular defect in migraine relates to the emergence of mutations in the CACNA1A gene that encodes the subunit of P/Q-type calcium channels in the motor nerve terminals. This study used single-fibre electromyography (SFEMG) to investigate the potential impact of an underlying channelopathy on subclinical neuromuscular transmission at the motor end plate in different types of migraine. Additionally, we sought to validate previous findings, explore the pathophysiology, and examine any potential relationship between neuromuscular dysfunction and disease severity using the Migraine Disability Assessment Scale (MIDAS) and Visual Analog Scale (VAS).\u0000Material and methods. We enrolled 25 healthy volunteers, 30 migraineurs with aura and 30 without aura diagnosed according to the 2018 criteria of the International Headache Society. Voluntary SFEMG was performed on the frontalis muscle. Jitter values were analysed, including the mean individual jitter values of the migraine group, the number of fibers with increased jitter, the mean Mean Consecutive Difference (MCD), and the lowest and highest jitter values, which were then compared with those of the control group. The intensity of the migraine attacks was assessed using the VAS, while disability was evaluated using the MIDAS.\u0000Results. Our findings revealed that the highest jitter values in migraine patients were significantly higher than those observed in the control group. Furthermore, we conducted a subgroup analysis within the migraine group and found that individuals with aura had higher average MCD values compared to those without aura and the control group. Additionally, we examined the association between MIDAS and VAS scores with increased jitter values and neuromuscular transmission abnormalities, but no statistically significant correlation was found (p=0.327).\u0000Conclusions. Our study supports the presence of motor endplate dysfunction in migraines, as indicated by previous literature, particularly in migraines with aura when compared to individuals without aura and controls. This finding aligns with the concept that this dysfunction may stem from a channelopathy associated with a genetic predisposition. Additionally, we found no clinical relationship between the neuromuscular disorder, the severity of the disease, and its disability.","PeriodicalId":16350,"journal":{"name":"Journal of Medical Science","volume":"4 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141379618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Comparative study between Ketamine and Propofol versus Ketamine and Dexmedetomidine for Monitored Anaesthesia Care for Dilatation and Curettage surgeries in Daycare procedures","authors":"Ayaskant Sahoo, Nagasatyasuryanarayana Ruttala, Rajendra Prasad, Swikruti Behera, E. Banavathu","doi":"10.20883/medical.e946","DOIUrl":"https://doi.org/10.20883/medical.e946","url":null,"abstract":"Introduction. Anaesthesia is frequently administered through Monitored Anaesthesia Care (MAC) utilising various combinations of anaesthetic drugs for moderately painful operations like Dilatation and Curettage (D&C), which is preferably done as a daycare procedure. The hunt for improved drug combinations is always ongoing, and the pharmacological properties of the individual drugs are considered. In this regard, anaesthesiologists all over the world are quite fond of the combination of Ketamine and Propofol, which is also known as Ketofol. Recently, especially in situations involving MRI sedation, the combination of ketamine and dexmedetomidine (Dexket) has gained popularity. This study compares the combinations for MAC during D&C surgeries in a daycare setting.\u0000Aim. The primary objective was to estimate the recovery times using either combination. Secondarily, we would also compare the duration of analgesia, the haemodynamics, and the side-effect profiles of the two combinations.\u0000Material and Methods. This study enrolled 60 patients posted for elective D&C. According to standard institutional protocols, they were administered Ketofol(KP group) or Dexket(KD group), depending on the anaesthesia provider’s choice. The Ketofol group received Ketamine 1mg/kg and Propofol 1mg/kg with boluses of Ketamine 0.25mg/kg to maintain the depth of anaesthesia using Ramsay sedation score(RSS) >3. KD group received Dexmedetomidine intravenously 1mic/kg over 10 minutes followed by ketamine 1mg/kg boluses of Ketamine 0.25mg/kg to maintain the adequate anaesthetic depth of RSS>3.\u0000Results. The Recovery time in post-operative period was significantly prolonged in the KD group (mean 22.77 minutes) compared to the KP group (mean 17.8 minutes). The total duration of analgesia was also longer in the KD group (250 minutes vs 220 minutes in the KP group). It was seen that the hemodynamic variables (HR, SBP, DBP) were consistently higher in the KD group compared to the KP group. There was a significant difference in SBP, DBP, and MAP in the intraoperative period between the KP and KD groups till 4hr in the postoperative period.\u0000Conclusions. We conclude that a combination of Dexmedetomidine and Ketamine has longer recovery times and analgesia duration than a combination of Propofol and Ketamine. Side effects like postoperative nausea and vomiting are not significant. However, since the recovery times are comparatively longer in a daycare setting, dexmedetomidine and Ketamine may not be the preferred agents compared to the combination of Ketamine and Propofol in the context of a daycare setting.","PeriodicalId":16350,"journal":{"name":"Journal of Medical Science","volume":" 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140390067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This manuscript examines the field of obesogen research, seeking to understand the mechanisms by which certain environmental chemicals contribute to the development of obesity. We explore the obesogenic effects by focusing on pathways such as inflammation, hormone interference, and the activation of peroxisome proliferator-activated receptors (PPARs). The text focuses on the significance of PPAR isoforms, especially PPARγ, and how they play a role in adipose tissue growth. We examine how obesogens such as tributyltin (TBT) and bisphenol A (BPA) influence these receptors. Additionally, we examined the impact of obesogens on hormonal regulation, including disruptions to leptin and adiponectin, and investigated the intricate relationship between chronic inflammation and obesity. In the methodology of our study, we utilized a systematic search to identify peer-reviewed articles of relevance. This search spanned various model systems, including in vitro, in vivo, and epidemiological studies, providing insights into the distinct advantages and limitations associated with each. Epigenetic modifications and the influence of obesogens on the development of adipose tissue, metabolism, and appetite control further enrich our understanding of this complex field. Finally, we assess the role of endocrine disruptors in amplifying the risk of obesity, emphasizing the heightened susceptibility during crucial developmental periods. This comprehensive review aims to contribute to the ongoing discourse surrounding obesogens, paving the way for targeted interventions and a more profound comprehension of the global obesity epidemic.","PeriodicalId":16350,"journal":{"name":"Journal of Medical Science","volume":" 36","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140389966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is beyond any doubt that discoveries made by Karikó and Weissman were pivotal in overcoming one of the major hurdles in the practical application of mRNA molecules, i.e., their recognition by endosomal Toll-like receptors and downstream innate immune response, ultimately leading to the decreased translational activity of exogenous mRNA molecules and their degradation.

In this study we are comparing Palonosetron and Normal Saline in decreasing pain on injection of propofol during intravenous induction of anaesthesia.\u0000Material and methods. One hundred adult patients belonging to ASA physical status I or II, scheduled for elective surgeries under general anaesthesia were selected and randomly allocated to two groups. Group P received Injection Palonosetron and Group S received Injection Normal Saline as pre-treatment before injection of propofol. Patients were assessed for pain on propofol injection.

Hendra and Nipah are two highly dangerous zoonotic viruses belonging to the group of henipaviruses. Although they have been known for more than 20 years, no human drug or vaccine has been invented for them. The aim of this paper is to describe the epidemiology of the reported paramyxoviruses, the pandemic potential of henipaviruses and a standardised action plan to counter their spread. This paper is a review of scientific articles from 2012-2023 published in the scientific databases such as Pubmed, Researchgate and Google Scholar. The following keywords were used: pandemic potential of henipaviruses, Hendra virus, Nipah virus, henipavirus epidemics.\u0000Description of the state of knowledge. The mortality rate of henipaviruses varies between 50-100%. The Nipah virus is particularly dangerous, with epidemics recurring virtually every year in Asia since 1998. The Hendra virus situation is more manageable because there is an effective vaccine for horses, which are most vulnerable to infection. Through anthropogenic changes, the terrain and climate where the animals that are the reservoir of the virus are found are changing. Due to the numerous outbreaks of henipaviruses in areas of Asia and Australia, great care is being taken to quickly neutralise the outbreaks that occur.\u0000Conclusions. Due to the high pandemic threat from henipaviruses, more research into drugs and vaccines is required. It is also important to develop effective bio-assurance plans, introduce controls on their operation and educate the population on the issue. Reservoir animals, through anthropogenic changes in the environment, are changing habitats and feeding sites, making more and more territories vulnerable to the disease. New species of henipaviruses are emerging all the time, posing an epizootic challenge to public health, so a key action is to increase the amount of research into the epidemic development of the virus and to conduct it as widely as possible.","PeriodicalId":16350,"journal":{"name":"Journal of Medical Science","volume":"110 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138590499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
