Infertility has troubled the world's 186 million people, and male infertility accounts for more than half. The literature of physical exercise related to semen quality has shown inconsistent results, and there is currently no systematic review to evaluate the effects of exercise on reproductive outcomes in male infertility patients. This study aims to assessing the effects of exercise interventions based on randomized controlled trials (RCTs) on semen quality and reproductive outcomes in male infertility. ⋯ PROSPERO CRD42019140294.

Mild cognitive impairment (MCI) is an intermediate stage between the cognitive changes of normal aging and early dementia. Tai Chi (TC) may be particularly beneficial to patients with MCI due to its whole-body coordination characteristics. This systematic review protocol aims to outline the methods that will be used to assess the comparative effectiveness and safety of TC for MCI through a systematic review and meta-analysis. ⋯ The findings of our study will provide updated evidence to determine whether TC is an effective intervention to patients with MCI.

Traumatic AOD is rare but highly associated with upper cervical spine injuries. We found no references in the literature of traumatic posterior atlantooccipital dislocation (AOD) combined with type II dens fracture (Anderson-D'Alonzo classification) and C1 anterior arch fracture. ⋯ A thorough clinical evaluation and radiologic investigation (CT and MRI) on concomitant upper cervical injuries should be evaluated in traumatic AOD patients.

A cross-sectional study on serum measles antibody levels of a healthy population in southwest China.
This study aimed to investigate measles antibody level and its associated factors in a healthy Chinese population, so as to provide evidence to measles prevention and control measures in the future. We conducted a cross-sectional survey by using probability proportionate to size sampling (PPS) among a healthy population aged 8 months to 45 years. Information on measles vaccination status was obtained from the vaccination certificates. ⋯ Ethnicity, age, area, and MVC immunization history were the influencing factors of antibody concentration. Our major findings suggest that, children in rural China, especially in impoverished mountainous regions, were more likely to suffer from delays in measles vaccination. Various measures in optimizing vaccination practices should be implemented in order to prevent possible measles epidemic, even outbreak in these regions.

Observational Study
Nomogram to predict overall survival and disease-specific survival with appendiceal mucinous adenocarcinoma.
To predict the survival of appendiceal mucinous adenocarcinoma (AMA) by prognostic nomogram. A total of 3234 patients with AMA were collected from the Surveillance, Epidemiology, and End Results (SEER) database from 1973 to 2015. Univariate and multivariate Cox proportional hazards (PH) regression analyses were used to generate independent prognostic factors. ⋯ The Calibration plots revealed that the actual survival and nomogram prediction had a good consistency. Build a nomogram in the SEER database to predict OS and DSS in patients with AMA. It can provide accurate and personalised survival prediction for clinicians and patients.
