Association of maternal serum triglycerides at term and macrosomia in gestational diabetes mellitus
Background: Aim of the study was to determine association of maternal serum triglycerides (TG) at term and macrosomia in gestational diabetes mellitus (GDM).
Methods: A cross sectional study was carried out in the department of obstetrics and gynaecology, RIMS, Manipur. The study was conducted for 2 years duration from September 2019 to August 2021 and 85 singleton term pregnant women with GDM were included. All the patients were subjected to check fasting serum TG, FBS, PPBS. Descriptive statistics like mean, standard deviation and Inferential statistics like Chi-square test was used for comparing study variables between large for gestational age (LGA) and non LGA group. T-test was used to compare the mean values of age, pre-pregnancy BMI, pregnancy weight gain, OGTT, FBS, PPBS, fasting serum TG between LGA and non LGA group.
Results: The observed mean TG values in LGA and non LGA group in our study was 262.35±26.08 and 158.18±13.24 mg/dL respectively. The serum TG values in the LGA group mothers was significantly higher when compared to the non LGA group. The mean weight gain in pregnancy 15.17±1.82 and 9.60±1.47 in LGA and non LGA respectively. The mean BMI comparison among LGA and non LGA are 27.7±1.74 and 22.94±1.6 respectively.
Conclusions: It is observed that maternal fasting serum TG may be a strong predictor of foetal size irrespective of the glycemic status. Our study clearly pointed out the usefulness of measuring serum TG in GDM pregnancy. In addition to maternal hypertriglyceridemia, pre-pregnancy BMI, excessive weight gain in pregnancy significantly associated with foetal macrosomia in GDM mothers
Chemical Composition and Antimicrobial Activity of Essential Oil from Eupatorium triplinerve Vahl. Aerial Parts
ABSTRACT Eupatorium triplinerve Vahl belongs to the Asteraceae family, popularly known as Ayapana .It is a perennial shrub native to Amazon rainforests of South America. Its leaves are used through infusions, decoctions, baths, and tea. It is largely used in Brazilian folk medicine as sedative, febrifuge, stimulant, tonic and anti-inflammatory. The essential oil from aerial parts of Eupatorium triplinerve was analysis by gas chromatography mass spectroscopy (GC-MS). Thirty compounds representing 98.24 % of the oil were identified. The major compounds were 2-tert-butyl -1, 4-methoxybenzene (74.3 %) and bSelinene (8.6 %). The antibacterial activity of the essential oil was evaluated against ten bacteria (including Gram positive and Gram negative) and six phytopathogenic fungi. The oil exhibited moderated antibacterial and strong antifungal activity against all the test pathogens. The highest zone inhibition was recorded against Salamella typhae (21mm) followed by Shigella sonnei (18mm) at a concentration of 20µl/ disc on the other standard Ampicillin 20mg/ disc showed on average of 14-34mm diameter of zone inhibition against the test organism. The lowest antifungal activities were recorded against Macrophomina phaseoline, and Botryodiplodia theobromae. The highest Alternaria alternate (12000ppm).Further pharmacological and toxicology studies will be required to establish the therapeutic uses of this oil

Risk of COVID-19 after natural infection or vaccinationResearch in context
Background: While vaccines have established utility against COVID-19, phase 3 efficacy studies have generally not comprehensively evaluated protection provided by previous infection or hybrid immunity (previous infection plus vaccination). Individual patient data from US government-supported harmonized vaccine trials provide an unprecedented sample population to address this issue. We characterized the protective efficacy of previous SARS-CoV-2 infection and hybrid immunity against COVID-19 early in the pandemic over three-to six-month follow-up and compared with vaccine-associated protection. Methods: In this post-hoc cross-protocol analysis of the Moderna, AstraZeneca, Janssen, and Novavax COVID-19 vaccine clinical trials, we allocated participants into four groups based on previous-infection status at enrolment and treatment: no previous infection/placebo; previous infection/placebo; no previous infection/vaccine; and previous infection/vaccine. The main outcome was RT-PCR-confirmed COVID-19 >7–15 days (per original protocols) after final study injection. We calculated crude and adjusted efficacy measures. Findings: Previous infection/placebo participants had a 92% decreased risk of future COVID-19 compared to no previous infection/placebo participants (overall hazard ratio [HR] ratio: 0.08; 95% CI: 0.05–0.13). Among single-dose Janssen participants, hybrid immunity conferred greater protection than vaccine alone (HR: 0.03; 95% CI: 0.01–0.10). Too few infections were observed to draw statistical inferences comparing hybrid immunity to vaccine alone for other trials. Vaccination, previous infection, and hybrid immunity all provided near-complete protection against severe disease. Interpretation: Previous infection, any hybrid immunity, and two-dose vaccination all provided substantial protection against symptomatic and severe COVID-19 through the early Delta period. Thus, as a surrogate for natural infection, vaccination remains the safest approach to protection. Funding: National Institutes of Health
