A novel, green, versatile and magnetically retrievable BiFeO<sub>3</sub>/CDR (Bismuth ferrite/coriander) nanocomposites were fabricated via simple wet chemical method utilizing in situ functionalized, cheap coriander seed powder (CDR 5%, 10%, 15% and 20 wt%) as a fuel to enhance the efficiency of pristine BiFeO<sub>3</sub>. A comparative study was performed between BiFeO<sub>3</sub>/CDR and BiFeO<sub>3</sub>/CNT (Bismuth ferrite/carbon nanotubes) nanocomposites for the removal of various hazardous pollutants from waste water. The successful synthesis of the fabricated nanomaterials was monitored via FT-IR, Powder XRD, FE-SEM, CV, VSM, CHNS/O and XPS studies. The synthesized nanomaterials were employed for the oxidative degradation of Carbol fuchsin, Reactive black 5, Ciprofloxacin and Doxorubicin; adsorption of a pesticide malathion; and reduction studies for Para-nitrophenol (PNP). The fabricated nanomaterials (BiFeO<sub>3</sub>/CDR) showcased excellent efficiency and comparable results with (BiFeO<sub>3</sub>/CNT) for the removal of model pollutants. Moreover, synthesized green heterojunction was also testified for mixture of textile and pharmaceutical waste. Hence CDR can be utilized as a better alternative of CNTs.

Objective: Examine the risks of fractures and osteoporosis after risk-reducing bilateral salpingo-oophorectomy (RRBSO) among women with mutations. Methods: In this retrospective population-based study in British Columbia, Canada, between 1996 to 2017, we compared risks of osteoporosis and fractures among women withmutations who underwent RRBSO before the age of 50 (n=329) with two age-matched groups without known mutations: 1) women who underwent bilateral oophorectomy (BO) (n=3,290); 2) women with intact ovaries who had hysterectomy or salpingectomy (n=3,290). Secondary outcomes were: having dual-energy X-ray absorptiometry (DEXA) scan, and bisphosphonates use. Results: The mean age at RRBSO was 42.4 years (range, 26–49) and the median follow-up for women with mutations was 6.9 years (range, 1.1–19.9). There was no increased hazard of fractures for women with mutations (adjusted hazard ratio [aHR]=0.80; 95% confidence interval [CI]=0.56–1.14 compared to women who had BO; aHR=1.02; 95% CI=0.65–1.61 compared to women with intact ovaries). Among women who had DEXA-scan, those with mutations had higher risk of osteoporosis (aHR=1.60; 95% CI=1.00–2.54 compared to women who had BO; aHR=2.49; 95% CI=1.44–4.28 compared to women with intact ovaries). Women with mutations were more likely to get DEXA-scan than either control groups, but only 46% of them were screened. Of the women withmutations diagnosed with osteoporosis, 36% received bisphosphonates. Conclusion: Women with mutations had higher risk of osteoporosis after RRBSO, but were not at increased risk of fractures during our follow-up. Low rates of DEXA-scan and bisphosphonates use indicate we can improve prevention of bone loss.

Background: To explore the relationship between persistent post-radiotherapy pain and locoregional recurrence in head and neck cancer patients. Methods: Five year retrospective data was reviewed of 86 patients of head and neck cancer treated with radiotherapy who continued to have pain at 6 weeks after completion of treatment. At follow-up after 3 months, these patients were stratified into: Group A (n = 39) constituted of patients whose pain subsided and Group B (n = 47) were patients who continued to have persistent pain. Results: At median follow-up time of 25 months (range: 8.47), one patient (2.6%) and 18 (38.3%) patients in group A and group B had locoregional recurrence respectively (P < 0.0001). Furthermore, group B patients had higher mean pain score levels as compared to group A (P = 0.03). Patients in whom pain subsided within 3 months had statistically much greater disease-free survival in comparison to those with persistent pain (P < 0.0001). Conclusions: Pain in head and neck cancer is an important symptom and should be considered a poor prognostic factor. In the current study, the majority of the patients with persistent pain had recurrent disease as compared to those in whom pain subsided within 3 months of post-treatment. It is suggested that patients with persistent pain need more intense follow-up and should be investigated thoroughly to detect recurrence at an early stage to provide a better quality of life.
