Context: The tuber of Amorphophallus paeoniifolius (Dennst.) Nicolson (Araceae), commonly called Suran or Jimmikand, has high medicinal value and is used ethnomedicinally for the treatment of different gastrointestinal and inflammatory disorders. Objective: The present study evaluated the effects of extracts of Amorphophallus paeoniifolius tubers on acetic acid-induced ulcerative colitis (UC) in rats. Materials and methods: Wistar rats were orally administered methanol extract (APME) or aqueous extract (APAE) (250 and 500 mg/kg) or standard drug, prednisolone (PRDS) (4 mg/kg) for 7 days. On 6th day of treatment, UC was induced by transrectal instillation of 4% acetic acid (AA) and after 48 h colitis was assessed by measuring colitis parameters, biochemical estimations and histology of colon. Results: APME or APAE pretreatment significantly (p < .05-.001) prevented AA-induced reduction in body weight and increase in colitis parameters viz. stool consistency, colon weight/length ratio and ulcer score, area and index. Extracts treatment attenuated (p < .001) increase in alkaline phosphatase and lactate dehydrogenase in serum and myeloperoxidase activity and cytokines in colon tissue due to AA administration. Extracts treatment prevented AA-induced elevation in lipid peroxidation and decline in activities of superoxide dismutase and catalase and reduced-glutathione content (p < .05-.001) along with histopathological alterations. PRDS also showed similar ameliorative effect on colitis. Discussion and conclusion: APME and APAE showed a preventive effect on UC, and ameliorated inflammation and oxidative damage in colon. The effects may be attributed to presence of phytochemicals, betulinic acid, b-sitosterol, and glucomannan. In conclusion, the tuber of Amorphophallus paeoniifolius exhibited an anticolitic effect through anti-inflammatory and antioxidant action.
ARTICLE HISTORY
Vascular origin tumors of bone are rare entities. Epithelioid hemangioendothelioma (EHE) is a rare tumor representing <1% of primary bone tumors and is considered a low to intermediate grade malignancy. Literature describes cases which were either a part of multicentric disease or were metastatic. In this study, we reported a case of a 23-year-old female with biopsy-proven EHE with prior history of resection, presenting with recurrence of disease. Radiographs showed a lytic lesion involving the left calceneum and other tarsal bones with extensive soft-tissue component. Magnetic resonance imaging revealed an ill-defined, enhancing, lobular, and lytic lesion with adjacent soft-tissues component. Computed tomography confirmed extensive destruction of the involved tarsal bones. EHE is treated with wide surgical excision and recurrence is rare; however, our case presented with recurrence as well as thoracic metastasis which posed a great clinical challenge. The patient was treated with below knee amputation and was given subsequent radiotherapy. The main aim of this study is to revisit the clinicopathological aspects as well as the spectral behavior of vascular bone tumors.
Background:
Gestational diabetes mellitus (GDM) is a common complication of pregnancy. Although GDM is associated with increased risk of cardiovascular disease it is unclear whether the associations between GDM prevalence and cardiometabolic risk factors differ between US- and foreign-born women and whether length of US residence influences these associations.
Methods:
We analyzed cross-sectional data from the 2016-2017 National Health Interview Survey among women currently living in the US who both reported ever being pregnant and responded to the survey question about GDM. Using generalized linear models with binomial distribution and logit link, we examined the prevalence of GDM by nativity status and length of US residence adjusting for potential confounders (Table).
Results:
Of 24,466 women, 14.3% were foreign-born. The crude prevalence of GDM was higher among foreign-born (9.0%) compared to US-born women (7.1%). Foreign-born women with ≥10 years of residence in the US had the highest age-standardized GDM prevalence (8.3%) compared to US-born (7.5%) and foreign-born women with <10 years US residence (4.8%). Among women with a history of GDM, US-born women were more likely to be overweight/ obese, report a history of hypertension, be current smokers and alcohol drinkers than foreign-born women. Among foreign-born women, those with ≥10 years of US residence had higher prevalence of hypertension, smoking and alcohol use than those with <10 years in the US. In the fully adjusted regression model, only foreign-born women with ≥10 years of residence in the US had a significantly higher prevalence of GDM than US-born women (PR=1.43; 95% CI:1.22-1.67).
Conclusions:
In this sample of women with self-reported GDM, greater length of US residence contributes to nativity-related disparities in GDM. Acculturation, including changing health-related behaviors, may have a larger impact on maternal health outcomes of foreign-born women, and should be a target of interventions to reduce GDM and future cardiovascular diseases.
