Introduction: Ankylosing Spondylitis is a chronic rheumatic arthritis with specifically related to lumbar spine and femoral neck. The disease is more common in young men. Inflame and inactive condition of patients with Ankylosing Spondylitis leads to a low bone mineral density. Determining osteomalacia has clinical significance because of the relation to bone density.\r\n', u'Objectives: To study the prevalence of osteoporosis and osteopenia in Ankylosing Spondylitis and to investigate correlation between bone mineral density and age at the beginning of the disease, BASDAI, BMI\r\n', u'Subjects and methods:119 male patients with ankylosing spondylitis, mean age of 29.0 \xb1 10.8 as defined by New York criteria modified in 1984. Bone mineral density was measured at the lumbar spine and hip with Unigamma X ray - Plus. Results: 26.1 % of patients had lumbar spine osteopenia and osteoporosis, while 41.2% had femoral neck osteopenia and osteoporosis. The beginning of the disease was 22.1 \xb1 7.8 and had correlation with bone density in lumbar spine. Low BMI group had decreased bone density in lumbar spine and femoral neck (BMI < 18.5), (p=0.0001 and p=0,005, respectively). Patients with active disease had lower bone density than those with stable disease.\r\n', u'Conclusion: Ankylosing spondylitis patients have decreased BMD values at both the spine and femur. Bone mineral density at lumbar spine and femoral neck had correlation with the BMI, Bone mineral density at femoral neck had correlation with BASDAI. \r\n', u'

Objectives: The study was conducted to comprehensively assess the status cervical cancer screening registry based on the experience of several countries and the domestic context, to propose related recommendations for Vietnam. Method: The study collected and evaluated the models and induced lessons in implementing and managing cervical cancer recording systems, from four countries/territory namely: Australia, Taiwan-China, Korea, and Thailand. Additionally, a literature review on policies documents and programs related to cervical cancer screening that have been implemented in Vietnam was also conducted. Results and Conclusion: All four selected countries/territory have prioritized to develop their cervical screening data management system with different models, all systems aimed at personalized management and used the data to evaluate the effectiveness of the screening program. Currently, there is no system to record and manage data on cervical screening in Vietnam. However, the country has many strengths and opportunities for the implementation of this program at the national level. The recommendations focus on the preparation and establishment of an integrated system for cervical cancer screening registry data, is suggested as a component of the information system of maternal and child health/ reproductive health, into the existing medical data management system, according to the short-term and long-term roadmap.

Objective: Female sex workers (FSWs) are at high risk of human papillomavirus (HPV) infections and cervical cancer due to their high number of sexual partners. The objectives of this study were to determine the prevalence of HPV and identify risk factors for high-risk HPV infection among FSWs in Hanoi and Ho Chi Minh City (HCMC), Viet Nam. Methods: A cross-sectional study was conducted in Hanoi and HCMC between December 2017 and May 2018. We surveyed and screened 699 FSWs aged ≥18 years for HPV infection and abnormal cytology. A multivariable modified Cox regression model was used to determine risk factors for high-risk HPV infection. Results The overall prevalence of any HPV, high-risk HPV and HPV-16/18 infection in the 699 FSWs was 26.3%, 17.6% and 4.0%, respectively, and were similar in both cities. Multiple infections were identified in 127 participants (69.0%).HPV-52 was the most prevalent (7%), followed by HPV-58 (6%). Abnormal cytology was detected in 91 participants (13.0%). FSWs who are divorced (adjusted prevalence ratio [aPR]: 1.96, 95% confidence interval [CI]: 1.01–3.81), widowed (aPR: 3.26, 95% CI: 1.49–7.12) or living alone (aPR: 1.85, 95% CI: 1.01–3.39) were associated with a higher prevalence of high-risk HPV infection.
