Integration of in vitro and in-silico analysis of Caulerpa racemosa against antioxidant, antidiabetic, and anticancer activities.

Marine algae are found to be excellent in their nutritional and potential therapeutic properties. This study explores the antidiabetic and anticancer potential of fractionated polyphenolic extract of Caulerpa racemosa, green macroalgae. Crude polyphenolic extract (CPE) of C. racemosa and its fractions (n-hexane, ethyl acetate, chloroform, and distilled water) were tested for its total phenol and flavonoid contents and antioxidant potential. The ethyl acetate fraction was subjected to gas chromatography/mass spectrometry (GC/MS). The in vitro antidiabetic activity was assessed by alpha-amylase, glucosidase inhibition and anti-glycation assays. Also, in-silico studies were conducted to test the binding affinities between caulerpin with alpha-glucosidase enzyme and estrogen receptor (ER) active sites. Each fraction was tested for its in vitroin vitroanticancer activity by CellTiter-Glo and MTT cell proliferation assays. The total phenolic and flavonoid contents and the antioxidant potential of the crude extract were observed to be dose dependent. The GC/MS analysis of the ethyl acetate fraction yielded 47 peaks, whereas n-hexadecanoic acid and hexadecanoic acid methyl ester showed the highest compatibility percentages of 99% and 96%, respectively. The CPE exhibited a higher potential in both alpha-amylase inhibitory and anti-glycation activities. The ethyl acetate fraction was more effective against alpha-glucosidase inhibition. Molecular docking revealed a high binding affinity between the alpha-glucosidase enzyme and caulerpin and showed high binding affinity toward caulerpin, with H-bond interactions. The in vitro anticancer analyses revealed that chloroform fraction and CPE exhibited moderate activity on the KAIMRC1 cell line. Also, the CPE exhibited high specificity compared to the standard drug in anticancer studies. Our findings evidence the pharmacological potential of the CPE of C. racemosa, and bioactive compounds of the species may be utilized as lead molecules to develop anti-diabetic and anti-cancer drugs.

Risk of Tuberculosis Infection among Healthcare Workers in a Tertiary Care Hospital in Bengaluru City.

INTRODUCTION: Tuberculosis (TB) is an airborne communicable disease caused by Mycobacterium tuberculosis. Infection is most likely to occur when an individual is exposed to someone with pulmonary TB on a day-to-day basis, such as by living or working in close quarters with someone who has an active disease. This study was undertaken using reliable screening and investigation tools for assessing the incident latent tuberculosis infection (LTBI) among healthcare workers (HCWs). METHODOLOGY: This descriptive longitudinal study was conducted among 600 HCWs at a tertiary care hospital in Bengaluru city for a period of 1 year 4 months (March 2016-June 2017). All HCWs were stratified according to their work profile as doctors, nurses, laboratory technicians, nursing aides, pharmacists, laundry workers (only those who come in contact with patients), dietary workers (only those who come in contact with patients), and workers from housekeeping department. Study subjects were enrolled in proportion to their population size. The data were collected by administering TB screening questionnaire and performing tuberculin skin test (TST). All the subjects who had negative TST reaction were followed up after 1 year from March 2017 to June 2017. RESULTS: The study subjects consisted of 600 HCWs with a mean age of 27.8 ± 7.1 years. Initially, 600 study subjects underwent TST, 2 of whom were not contactable between 48 and 72 h of test administration. Of the remaining 598 subjects, 120 (20.1%) had a positive TST reaction. After 1 year, of the 478 subjects who tested negative, 345 study subjects underwent the repeat TST and 67 (19.4%) of the study subjects had a positive TST reaction. CONCLUSION: The prevalence of LTBI was 20.1% and it was significantly associated with age, place of residence, education, work commute time, and mode of transport. The incidence of LTBI was 19.4% and it was significantly associated with gender, place of residence, education, work commute time, and marital status.

Effectiveness of Color Coded Diabetic Control Monitoring Charts among Elderly Diabetics Attending Outreach Primary Care Geriatric Clinics in Rural Karnataka: An Open Label Randomized Control Trial.

INTRODUCTION: Type 2 diabetes mellitus problem is progressively rising every day. The adherence to the treatment approaches and health-seeking make major difference in case of diabetics particularly elderly. Visual tools improve the involvement of patients in their care, especially among populations with low health literacy. OBJECTIVE: To evaluate the effectiveness of color-coded diabetic control monitoring charts on glycemic control among elderly diabetics. METHODOLOGY: 144 elderly diabetic patients attending rural primary care geriatric clinics were randomized into two groups. Those randomized to the intervention group received the color-coded diabetic monitoring chart and a health education package in addition to the usual consultation services. Baseline and 1-year follow-up glycated hemoglobin (HbA1C) values were used to assess the effectiveness of the intervention. RESULTS: The results of multivariate linear regression analysis showed that there was an average reduction of 0.265% in HbA1C value in the intervention group when compared to the nonintervention group when adjusted for baseline HbA1C and number of visits during the intervention period (ß coefficient = 0.265, P < 0.05). CONCLUSION: Color-coded diabetes charts are effective in achieving glycemic control among elderly diabetics, and steps should be made to inculcate visually appealing management approaches in case of elderly diabetic patients.
