High Risk of Malnutrition in Uyghur Patients with Cancer in China

Background Patients with advanced cancer often present with malnutrition.Globally,minority populations frequently suffer from higher rates of malnutrition than the majority group.It was unknown whether the nutritional status of cancer patients is different between ethicality groups(i.e.Uyghur and Han)in China.Methods A total of 251 Uyghur cancer patients were enrolled from the Xinjiang Kashgar First People's Hospital in the INSCOC Program.The Han patients were 1∶1 matched to Uyghur patients by age,gender and type of cancer from 72 hospitals around China in INSCOC Program.The nutritional risk and nutritional status were assessed using the Nutrition Risk Screening 2002(NRS 2002)and Patient-Generated Subjective Global Assessment(PG-SGA),respectively.Then,the functional status of cancer patients was determined based on the Karnofsky Performance Status(KPS).Results The incidence of an abnormal NRS-2002(≥3),PG-SGA(≥4),and KPS(≤70)was significantly different(86.1%vs 59.0%,70.5%vs 27.5%,and 18.7%vs 4.0%,respectively P<0.05).The abnormal rate of laboratory indicators in Uyghur cancer patients was significantly higher than that in Han cancer patients,including total protein,albumin,serum total bilirubin,direct bilirubin,HDL-C,white blood cell,lymphocyte,red blood cell,and platelet(all P<0.05).The abnormal rates of TSF,HGS and CC were significantly higher than that of Han nationality patients(17.5%vs 9.7%,39.6%vs 19.6%,29.1%vs 15.2%,P<0.001).The nutritional support rate of Uyghur patients was lower than that of Han patients(0%vs 16.3%).After adjusting for potential risk factors,malnutrition was associated with gender(female,OR=0.35,95%CI=0.13-0.92,P=0.034),age(>60 years,OR=5.32,95%CI=1.46-19.41,P=0.011),cancer type(gastroesophageal tumor,OR=33.62,95%CI=3.42-330.67,P=0.003),and treatment methods(received radical tumor resection,OR=5.78,95%CI=1.45-23.08,P=0.008;received radiotherapy or chemotherapy:OR=7.69,95%CI=2.27-26.04,P<0.001).Conclusions The nutritional status of Uyghur cancer patients is worse than that of Han patients and the Uyghur patients with poor nutritional status lack the necessary nutritional support.

Oral Contraceptives and Health Outcomes:an Umbrella Review of Systematic Reviews and Meta-analyses in Women and Offspring

Aim We herein provide an umbrella review of systematic reviews(SR)and meta-analyses(MAs)of studies of the association of oral contraceptives(OCs)with the risks of multiple health outcomes in women and their descendants.Methods Two investigators retrieved publications from four electronic databases,including PubMed,Embase,Web of Science,and the Cochrane Database of Systematic Reviews up to March 15,2021.For each association,random/fixed-effects summary effect size and 95%CIs were estimated.Heterogeneity and publication bias were also assessed.The method quality and evidence level for each publication were respectively assessed utilizing the AMSTAR and GRADE checklists.Results A total of 68 articles with 82 unique outcomes were included based on the eligibility criteria.Numerous lines of evidence indicated that OCs had effects on nearly all cardiovascular disease-related outcomes,especially for cerebral venous sinus thrombosis(OR=7.59,95%CI:3.82-15.09).Harmful associations were also found for vulvar vestibulitis(OR=2.31,95%CI:1.03-5.16),preterm birth(OR=1.17,95%CI:1.07-1.27),miscarriage(OR=1.13,95%CI:1.02-1.72),ulcerative colitis(OR=1.22,95%CI:1.06-1.41),Crohn's disease(OR=1.24,95%CI:1.09-1.40),alveolar osteitis(RR=1.86,95%CI:1.66-2.08),dry socket(RR=1.8,95%CI:1.33-2.43),and interstitial cystitis(OR=2.1,95%CI:1.26-3.49).However,oral contraceptives did not increase the risk of cancer except breast and cervical cancer.Maternal exposure to OCs was linked to an increased risk for the development of respiratory atopic disorders such as asthma(OR=1.1,95%CI:1.02-1.19)and rhinitis(OR=1.34,95%CI:1.07-1.68).Conclusion In summary,although their use obviously reduces the risk of pregnancy-and parturition-related morbidity and mortality for women,OCs were frequently related to more harm than benefit in terms of other health outcomes.This was true for both women and their descendants in this umbrella review.More large-scale prospective studies analysing different doses,structures,and durations of treatment with estrogen and progestin are needed to confirm these effects.

The Association between LINC00511 Variants and Breast Cancer Susceptibility among the Han Chinese Population

Objective LINC00511 has been considered an oncogene for breast cancer,however,the association between LINC00511 Single nucleotide polymorphisms(SNPs)and breast cancer risk remains unclear.Methods A total of 504 breast cancer patients and 505 cancer-free controls were genotyped for 12 LINC00511 SNPs.A logistic regression analysis was conducted to explore the association between LINC00511 SNPs and breast cancer susceptibility,adjusting for reproductive factors.A haplotype analysis and interaction analysis were applied to assess the role of LINC00511 in breast cancer.Results LINC00511 SNPs were significantly correlated with breast cancer.The TT genotype of rs11657109 reduced the risk of breast cancer(OR:0.454,95%CI:0.212-0.970),while the AG and GG genotypes of rs17780195 played a protective role(OR:0.723,95%CI:0.539-0.970;OR:0.398,95%CI:0.184-0.860,respectively).The mutation of rs9906859 may also lead to a reduction in breast cancer susceptibility(OR:0.682,95%CI:0.520-0.894).Furthermore,LINC00511 SNPs(rs4432291,rs1558535,rs17780195 and rs9906859)are associated with the HER-2 status(P<0.05 for all).The interaction of rs9906859,breastfeeding and age increased the breast cancer risk by 4.318(OR:5.318,95%CI:2.214-12.774).Conclusions LINC00511 SNPs were associated with the risk of breast cancer.There was an association between LINC00511 SNPs and the HER-2 status.There were interactions between LINC00511 SNPs and reproductive factors that affected the risk of breast cancer.
