A study on social media and higher education during the COVID-19 pandemic.

Nowadays social media usage has increased drastically among the stakeholders of higher educational institutions. The COVID-19 pandemic has suddenly increased the surge of social media users due to the forced implementation of online pedagogy and travel restrictions. The research study presented in this paper attempted to analyze social media usage in higher education. The data were collected from primary and secondary sources with the help of leading research databases, survey questionnaires, the Delphi method, and brainstorming sessions. Statistical tools and analytic techniques incorporated in the study included bibliometric analysis, word cloud, co-occurrence network, thematic map, thematic evolution, co-word analysis, country-wise analysis along with collaboration network, statistical survey, mind mapping, and analytic hierarchy process. The study justified the aspects of social media usage in the higher educational environment. It was found that the research fraternity around the globe focused more on understanding the aspects of social media and higher education during the trying times of the Coronavirus crisis. The maximum impact of social media usage on higher education was found to be from teaching-learning and discussions, and public relations and networking. It was also found that social networking platforms like WhatsApp, YouTube, Facebook (Meta), LinkedIn, Instagram, and Twitter were very common among the stakeholders of higher education. This study is of huge importance because it can help in paving the way to strategize remedial measures for increasing positivity and minimizing the negativity of social media usage in institutions of higher education across the world.

Incidence of anaemia among the female tea garden workers in a tea plantation in upper Assam, India.

Nutritional anaemia is the most common type and cause of anaemia. Tea garden workers constitute approximately 1/5th of population in the state of Assam. Reports indicate higher prevalence of undernutrition in this population. The present study was designed to focus on the incidence of anaemia among the female tea garden workers and to examine the effect of iron with vitamin B12 and folic acid supplementation in them. Two hundred and forty-four female tea garden workers who could be persuaded to participate in the study were sampled for haemoglobin typing by agarose gel electrophoresis (pH 8.9). Their haematological parameters were measured on automated cell counter to read Hb, RBC, MCV, MCH and MCHC. BMI was calculated from weight/height in metre2. The study revealed 182 anaemic (<11.0 g/dl) subjects which included 32 cases of hereditary anaemia and 150 cases of nutritional anaemia. Iron supplementation for duration of 3 months was given to 150 workers out of total 182 subjects who had haemoglobin <11.0 g/dl. Thirteen subjects with haemoglobin >11.0 g/dl were studied as controls. Level of haemoglobin was rechecked after 3 months by Sahli's method. Based on the size of red blood cells it was observed that the workers suffered from all three forms of anaemia viz, microcytic, normocytic and macrocytic. There was a significant rise in haemoglobin concentration when the anaemic individuals took iron with vitamin B12 and folic acid supplement for three consecutive months supported by two doses of anthelminthic drug. The present study showed that nutritional anaemia is a major problem in the female tea garden workers and arrangement of supplementation therapy is utmost necessary to improve their general condition and work efficiency.

Prevalence of CYP1A1 and GST polymorphisms in the population of northeastern India and susceptibility of oral cancer.

Individual cancer susceptibility is the result of several host factors, including differences in lifestyle habits and genetic susceptibility. There is a correlation between CYP1A1 polymorphism (MspI) and oral cancer susceptibility. Individuals carrying the deletions of GSTM1 and GSTT1 are at high risk of developing oral cancers. In the present study on healthy tribal and nontribal individuals of Assam, we found that the genetic variation of GSST polymorphisms is evident (p = 0.20) with differential dose of toxic exposure. Prevalence of different polymorphic alleles of CYP1A1 also proves the same result. A mini-case-control study with very small sample size showed no marked increase in the risk of developing oral cancer as the frequencies of the studied GST genotypes did not show any statistical significance. But GSTT1-null genotypes were found to have higher risk of developing leukoplakia (OR 1.94, 95% CI 2.61-18.54). CYP1A1 genotype m2 allele was also not found to be associated with the risk of developing leukoplakias in the population.

HbE genotypes and fertility: a study on a Tibeto-Burmese population in Upper Assam, India.

BACKGROUND: The north-eastern states of India in general and the state of Assam in particular appear to be areas with a very high incidence of HbE, with the highest frequency of the allele observed among the Kachari population. AIM: In the present study a Tibeto-Burmese speaking population of Assam, India has been studied with regard to haemoglobin E (HbE) and to examine the role of different HbE genotypes on fertility. SUBJECTS AND METHODS: Detailed reproductive histories and socio-economic data were collected from 159 unrelated Mishing (a Tibeto-Burmese population) couples initially. Haemoglobin typing was done by restriction digestion to detect wild type (HbA/HbA), heterozygotes (HbA/HbE) and homozygotes (HbE/HbE). RESULTS AND CONCLUSION: The HbE gene frequency for the total 318 individuals was 0.4623. The results suggest that HbE homozygosity is associated with a higher pregnancy rate. Mothers homozygous for HbE also have more live births in spite of having more spontaneous abortions. The study shows that HbE homozygous women may be getting an advantage up to the point of conception but beyond that various factors come into play to increase miscarriage and infant mortality and that the socio-economic factor is one important reason behind this.

Alpha-thalassemia among tribal populations of Eastern India.

Five hundred and thirteen unrelated subjects belonging to various tribes of West Bengal, Arunachal Pradesh and Assam in Eastern India, were screened for the presence of alpha-thalassemia (thal) gene deletion(s) as a possible cause of unexplained anemia (Hb < 11 g/dL and/or MCH <28 pg, MCV < 78 fL). As reported earlier, beta-globin gene mutant alleles were found with a frequency of up to 20% in some tribes. In the present study, alpha-globin gene deletion alleles were found in 18% of subjects from West Bengal, 3.9% from Arunachal Pradesh and 3.84% from Assam tribesmen. Coexistence of alpha- and beta-globin gene abnormalities was observed in up to 18% of some tribal groups. The high inbreeding rate and lack of appropriate medical care make these populations particularly vulnerable.
