In silico, anti-inflammatory and acute toxicological evaluation of an indigenous medicinal plant Pterospermum rubiginosum using Sprague-Dawley rats

BACKGROUND

Pterospermum rubiginosum has been traditionally used by the tribal inhabitants of Southern India for treating bone fractures and as a local anti-inflammatory agent; however, experimental evidence to support this traditional usage is lacking. The present study aimed to investigate the phytochemical characterization, in silico and in vitro anti-inflammatory evaluation, followed by in vivo toxicological screening of P. rubiginosum methanolic bark extract (PRME).

RESULTS

The LCMS evaluation revealed the presence of 80 significant peaks; nearly 50 molecules were identified using the LCMS database. In silico analysis showed notable interactions with inducible nitric oxide synthase (iNOS) and interleukin-6 (IL-6). In vitro gene expression study supported the docking results with significant down-regulation of iNOS, IL-6, and IL-10. PRME was administered orally to the SD rats and was found to be non-toxic up to 1000 mg/kg body weight for 14 days. The antioxidant enzymes catalase and sodium dismutase exhibited an increased value in PRME-administered groups, possibly due to the diverse phytochemical combinations in bark extract.

CONCLUSIONS

PRME administration significantly downregulated the gene expression of inflammatory markers, such as iNOS, IL-6, and IL-10. The molecular docking analysis of iNOS and IL-6 supports the in vitro study. In vivo toxicological study of PRME in SD rats was found to be non-toxic up to a concentration of 1000 mg/kg body weight for 14 days.

Predictors of maternal and fetal outcome in severely anemic pregnant mothers: A sequential mixed methods study

Introduction

Severe anemia in pregnancy increases maternal and neonatal morbidity and mortality in the antenatal period.

Objective

To find out the maternal and fetal outcomes in severely anemic pregnant women and explore the reason for the persistence of severe anemia in pregnant women.

Materials and Methods

Sequential explanatory mixed method study (Quan-Qual) was conducted in the Government Women and Children Hospital for a period of 1 and half years. Most of the people were from rural backgrounds and belonging to low socioeconomic status have been registered. Quantitative data were collected from 125 severe anemic cases; a consecutive sampling technique was applied. In-depth interviews were conducted among purposively selected severe anemic patients (n = 15) who were vocal and willing to explore the reason for the persistence of anemia. The interviews were conducted till the point of saturation. Ethical principles were adhered throughout the study. Quantitative data were anlyzed using SPSS software. Manual content analysis was done for qualitative data.

Results

Among 125 severe anemic patients, 12.8% patients had preterm labour, about 23.2% had inadequate lactation, and 13.6% had a puerperal febrile illness. It was found 41.6% of neonates had respiratory distress and 33.6% had the refusal of feeds. When compared to vaginal delivery, women undergoing cesarean section have 3.2 times (95% confidence interval 1.39-7.32) higher odds of developing maternal complications. Nagelkerke's R2 value for the model was 11.1%. Five broad categories namely Family centric nature, Lack of awareness, Pill burden, Food Fads, and Myths related to iron intake emerged from the study.

Conclusion

Complications can occur in mothers and neonates if anemia is not corrected in early trimester.

Risk of mental health disorders among farmers involved in palm plantation occupation

OBJECTIVE

The aim of this study was to define mental health status of palm plantation farmers in Muar, Johor, Malaysia.

MATERIALS AND METHODS

47 male farmers volunteered to join this study from three rural districts in southern Malaysia. Anthropometric measurements, demographic data including smoking habits and the short form of the Depression-Anxiety-Stress Scales (DASS-21) to assess mental health status were obtained in an interview.

RESULTS

Mean and SD age of participants was 30.17 ± 4.86 years. Mean BMI of subjects was 22.86 ± 3.88 kg/m2. Most subjects (76.6%) were smokers. The prevalence of mild to moderate anxiety was 27.7% and Mild to moderate depression was 8.5%.

CONCLUSIONS

This study revealed high prevalence of anxiety and smoking in palm plantation workers and that smoking habits can be related to their higher anxiety level.
