Ileocolic vascular curvature and ectopic cecal location were the only features independently and significantly associated with cecal volvulus in multivariable regression (odds ratio 178, p = 0.014, and 63, p = 0.013, respectively) and also the only features with both sensitivity (12/14 [85.7%, 95% CI 57.2-98.2%] and 13/14 [92.9%, 95% CI 66.1-99.8%], respectively) and specificity (40/40 [100.0%, 95% CI 91.2-100.0%] and 38/40 [95.0%, 95% CI 83.1-99.4%], respectively) that differed significantly from 50.0%. CONCLUSIONS Ileocolic vascular curvature was independently and significantly associated with cecal volvulus and exhibited both substantial sensitivity and substantial specificity for cecal volvulus, and thus is potentially a valuable new CT finding of cecal volvulus.BACKGROUND Breast cancer treatment is an established cause of financial toxicity, and associated costs may contribute to higher mortality and morbidity rates. In Egypt, breast cancer incidence and mortality rates are among the highest in the Middle East. Late-stage diagnosis is common, and disease occurs at an earlier age than in Europe and North America. Out-of-pocket payments are the primary means of financing healthcare in Egypt, and socioeconomic factors have been shown to significantly impact access to cancer screening and treatment. METHODS An observational cross-sectional study was conducted among breast cancer patients at Ain Shams University Hospitals in Cairo from 2013 to 2015. RESULTS One hundred women with breast cancer participated. Erlotinib purchase There was a high need for financial assistance (66.0%) and patients with financial needs had great difficulty affording medications (80.0%). A number of patients had lost their jobs following diagnosis, with 32.7% employed prior to diagnosis and 15.3% afterwards. Nearly one-half of participants were classified as food insecure, and nearly one-third reported difficulty affording transportation costs. CONCLUSIONS This is the first study to describe socioeconomic needs and financial impact among a cohort of Egyptian women undergoing breast cancer treatment. The findings highlight the financial impact of breast cancer treatment on a cohort of Egyptian breast cancer patients and the need for a multidisciplinary approach to help them access and mitigate the costs of treatment. Recommendations include implementing patient financial navigation services and producing printed materials to inform patients of resources to help mitigate the treatment's financial impact.PURPOSE To evaluate the uptake and effect of RENEW, a 12-week exercise referral programme for young adult cancer survivors delivered by Trekstock, a UK-based cancer charity. METHODS The RENEW programme provides one-to-one individually tailored support from a level-4 cancer-rehabilitation-qualified gym instructor, free gym membership and access to information resources online. Objective and self-report data on cardiorespiratory function, strength, body composition, fatigue, sleep quality and general health-related quality of life (HRQoL) was collected from participants before the programme (week 0), immediately after (week 12) and 1 month later (week 16). RESULTS Forty-eight young adults (83% female; mean age, 29 years) with a history of cancer took part within the 12-week programme and completed the evaluation measures. Physical activity (PA) levels significantly increased following the programme and remained raised at follow-up. Improvements in physical function were significant peak expiratory flow (mean ch care of young adults with cancer should look to address factors which prevent engagement and uptake of 'real-world' PA interventions such as the RENEW programme.Syntaxins are SNARE proteins and may play a role in epithelial sodium channel (ENaC) trafficking. The aim of the present study was to investigate the effects of syntaxin 2 (STX2), syntaxin 3 (STX3), and syntaxin 4 (STX4) on rat (rENaC) and human ENaC (hENaC). Co-expression of rENaC and STX3 or STX4 in Xenopus laevis oocytes increased amiloride-sensitive whole-cell currents (ΔIami) on average by 50% and 135%, respectively, compared to oocytes expressing rENaC alone. In contrast, STX2 had no significant effect on rENaC. Similar to its effect on rENaC, STX3 stimulated hENaC by 48%. In contrast, STX2 and STX4 inhibited hENaC by 51% and 44%, respectively. Using rENaC carrying a FLAG tag in the extracellular loop of the β-subunit, we demonstrated that the stimulatory effects of STX3 and STX4 on ΔIami were associated with an increased expression of the channel at the cell surface. Co-expression of STX3 or STX4 did not significantly alter the degree of proteolytic channel activation by chymotrypsin. STX3 had no effect on the inhibition of rENaC by brefeldin A, and the stimulatory effect of STX3 was preserved in the presence of dominant negative Rab11. This indicates that the stimulatory effect of STX3 is not mediated by inhibiting channel retrieval or by stimulating fusion of recycling endosomes. Our results suggest that the effects of syntaxins on ENaC are isoform and species dependent. Furthermore, our results demonstrate that STX3 increases ENaC expression at the cell surface, probably by enhancing insertion of vesicles carrying newly synthesized channels.Complete plastomes of Rheum species facilitated to clarify the phylogeny of Polygonaceae, and comparative chloroplast genomics contributed to develop genetic markers for the authentication of Rheum species. Rheum (Polygonaceae) is widely distributed throughout the temperate and subtropical areas of Asian interior. Rheum species are usually perennial herbs, and half of them are endemic to China with important medicinal properties. On account of similar morphological characteristics, species delimitation of Rheum still remains unclear. Chloroplast genomes of eight Rheum species, Rumex crispus and Oxyria digyna were characterized. Based on the comparison of genome structure of these species and the two published Rheum species, it is shown that plastome sequences of these species are relatively conserved with the same gene order, and three Sect. Palmata species remarkably showed high sequence similarities. Some hotspots could be used to discriminate the Rheum species, and 17 plastid genes were subject to positive selection.
