Paper-based test could diagnose hepatitis B and assess male fertility at low cost

(American Chemical Society) Scientists have developed a new paper device that analyzes DNA and could rapidly and inexpensively assess disparate conditions including hepatitis B and male infertility, which together affect millions of people around the world. The test, reported in the Journal of the American Chemical Society, could be of particular help diagnosing people in low-income areas.

ConclusionsPrimary infection with HBV, HCV, or HIV is an extremely rare event among Israeli infertile patients, and the risk for seroconversion in this population is practically nil. Annual screening of both partners leads to substantial costs and appears to be futile. Our results question the current practice and support increasing the interval between screening tests in low-risk populations.

This report presents baseline estimates of the use of these preventive services before the publication of QFP that can be used to monitor progress toward improving the quality of preventive care received by women and men of reproductive age. PERIOD COVERED: 2011-2013. DESCRIPTION OF THE SYSTEM: Three surveillance systems were used to document receipt of preventive health services among women and men of reproductive age as recommended in QFP. The National Survey of Family Growth (NSFG) collects data on factors that influence reproductive health in the United States since 1973, with a focus on fertility, sexual act...

BACKGROUND:Viral hepatitis B (HBV) and C (HCV) are a major public health problem in Saudi Arabia. Recent data has indicated a major reduction in viral hepatitis prevalence in Saudi population. However, there is limited data for infertile Saudi couples.  OBJECTIVES: To determine the prevalence of HCV and HBV attending an in vitro fertilization (IVF) clinic in Saudi Arabia between 2012 and 2015 to compare with the prevalence 10 years earlier in the same center.  DESIGN: Retrospective prevalence study. SETTING: Tertiary care center in Riyadh. PATIENTS AND METHODS: Data on the prevalence of HBV an...

Discussion Of the 30 different microbes which can be transmitted by sexual contact, 8 have the greatest incidence of transmitting disease. Four are curable (Chlamydia, Gonorrhea, Syphilis and Trichomoniasis) and 4 are incurable at present (Hepatitis B, Herpes simplex virus (HSV), Human immunodeficiency virus (HIV) and Human papillomavirus (HPV)). Sexually transmitted infections (STIs) are important as they can cause: Increased rates of acquisition of other STIs (ie HSV and syphilis increase the rate of HIV infection acquisition) Pelvic inflammatory disease and infertility Stillbirth and neonatal death Neonatal morbidity i...

ProblemThe relationship between hepatitis B (HBV) infection in infertile couples seeking in vitro fertilization (IVF) treatment and infertility causes is unknown. Methods of studyA total of 831 infertile couples attending our unit seeking IVF during January to December 2015 were recruited. ResultsHBV infection was found in 6.3% and 7.3% of female and male partners, respectively, and infection in one or both partners was associated with less primary infertility (44.2% vs 55.1%, P=.038). Infected female partners had increased tubal (69.2% vs 43.2%, P

ProblemThe effects of hepatitis B virus (HBV) infection on sperm quality and oxidative stress state of the semen of infertile males remain undetermined. Method of studyNormal males and 60 semen samples from infertile males (with or without HBV infection) were subjected to semen analysis. ResultsSemen volume, semen pH, sperm density, percentage of forward, movement of sperm, sperm activation rate, sperm survival rate, rate of normal sperm morphology of infertile males with HBV infection were significantly lower than those of infertile males without genital infection and of normal males (P

Conclusion A growing number of today’s children suffer from vaccine damage. Most individuals do not make the connection between health problems and vaccines. When asked about the cause of autoimmune disorders, asthma, allergies, diabetes, learning disabilities, attention deficit disorder, autism, and other common childhood diseases and illness, the majority of health care providers advise patients that the causes are unknown. Doctors, including most integrative physicians, fail to make the connection to vaccines. It takes one moment to permanently damage the health of an adult or child, but t...
