Background: Mycoplasma bovis (M. bovis) is a highly contagious cattle pathogen spreading worldwide and especially in Ningxia Hui Autonomous Region in China. Results: Two types of ST, ST10and ST134, were identified in Ningxia Hui Autonomous Region. Thirty-seven strains belonged to ST10 and 28 strains belonged to ST134. ST134 was a new ST and first found in 2009 and was only widely distributed in Ningxia Hui Autonomous Region at present. The M. bovis ST10 was widely spread in many provinces in China and was widespread in Ningxia Hui Autonomous Region since 2010. It is speculated that the prevalence of M. bovis ST10 in Ningxia Hui Autonomous Region began in 2010. Conclusions: This study is the first report on the genetic diversity of M. bovis from 2009 to 2018 in Ningxia Hui Autonomous Region and provides the epidemiological information. These results may help further our understanding of the evolution of M. bovis and provide information that may be useful for the development of novel vaccines. [ABSTRACT FROM AUTHOR]

Purpose: It is well-known that obesity has an adverse impact on breast cancer prognosis; nonetheless, the prognostic role of abdominal obesity, especially its post-diagnosis change, has been understudied. This study aims to examine the prospective associations of general and abdominal obesity and their post-diagnosis changes with all-cause mortality, breast cancer-specific mortality, and breast cancer recurrence in Chinese breast cancer patients., Methods: From 2011 to 2014, 1460 Chinese breast cancer patients were recruited and followed up at 18, 36, and 60 months after diagnosis. Body mass index (BMI), waist-to-hip ratio (WHR), and their changes between baseline and 18-month follow-up were derived. Clinical records on diagnosis, treatment, and death were also obtained. In total, 1309 women who completed the 18-month follow-up were included for Cox regression analyses, stratified by follow-up periods., Results: Within 18-48 months post-diagnosis, substantial WHR loss (5% or above) had reduced risk of all-cause (HR = 0.21 [95% CI 0.06-0.75]) and breast cancer-specific mortality (0.21 [0.06-0.77]) relative to stable WHR; whereas after 48 months post-diagnosis, substantial WHR gain showed elevated risks of all-cause mortality (2.67 [1.22-5.85])). Higher baseline WHR was also associated with both mortality outcomes. Nonetheless, no such associations were observed for BMI measures. Also, the effects of obesity measures on breast recurrence were less apparent., Conclusion: Abdominal obesity, rather than general obesity, was linked to worse survival in Chinese breast cancer patients. Prevention on abdominal obesity and waist gain following breast cancer diagnosis may have a beneficial effect on longer-term survival over and above conventional weight management. Waist assessment and abdominal obesity control should therefore be incorporated as a vital component of the evaluation and interventions of breast cancer prognosis., (© 2022.

Objective: This study assessed menopausal symptoms (MPS) after breast cancer in relation to quality of life (QoL) during the first 5 years of survival., Methods: An ongoing prospective study enrolled 1,462 Chinese women with early-stage breast cancer. They were longitudinally followed up at four time-points, namely baseline, 18-, 36-, and 60-month after diagnosis. At each follow-up, Menopause Rating Scale (MRS) and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 were used to assess MPS and QoL, respectively., Results: In total, 1,462, 1,289, 1,125, and 1,116 patients were included into the analyses at baseline, 18-, 36-, and 60-months, respectively. The percentages of patients with no or little, mild, moderate, and severe MPS at baseline were 31.8%, 30.0%, 30.4%, and 7.7%, respectively; the corresponding figures at 18-, 36-, and 60-month follow-up were similar. Using data from four follow-ups, Generalized Estimating Equations analyses showed that MPS was inversely associated with QoL. Higher MRS scores were related to lower QoL scores. For instance, every 1 point increase in MRS score was associated with a 1.5 point decrease in global health status/QoL score (P < 0.01). In terms of symptoms, higher MRS scores were related to more severe symptoms., Conclusions: This study highlighted patients with more severe MPS tend to have worse QoL. Future investigation should be conducted to assess different means of alleviating MPS to improve patient's QoL., Competing Interests: Financial disclosure/conflicts of interest: A.C. has received funding from Pfizer and Astellas.
