Evaluation of a novel triplex immunochromatographic test for rapid simultaneous detection of norovirus, rotavirus, and adenovirus on a single strip test.

Background: Acute gastroenteritis is one of the major causes of morbidity and mortality in young children worldwide. Among these, rotavirus, norovirus, and adenovirus have been reported as the primary viral pathogens associated with the disease. Rapid diagnosis of viral pathogens is crucial when diarrhea outbreaks occur to ensure the timely administration of appropriate treatment and control measures.

Role of rotavirus vaccination on G9P[8] rotavirus strain during a seasonal outbreak in Japan.

Although two live oral rotavirus (RV) vaccines, Rotarix and RotaTeq, play a critical role toward reducing disease severity, hospitalization, and death rate in RV infections, regular monitoring of vaccine effectiveness (VE) is yet necessary because the segmented genome structure and reassortment capability of RVs pose considerable threats toward waning VE. In this study, we examined the VE by a test-negative study design against G9P[8]I2 strain during a seasonal outbreak in February-May, 2018, in an outpatient clinic in Kyoto Prefecture, Japan. It remains important because G9P[8]I2 strain remains partially heterotypic to these vaccines and predominating in post-vaccination era.

Characteristics of Mother-Daughter Relationships and Sexual Risk-Coping Consciousness among Japanese Female University Students.

For heterosexual Japanese women in their early 20s, it is important to maintain good sexual health, develop intimate relationships with a partner, and go through the process of having a family. This study aimed to determine the characteristics of mother-daughter relationships among Japanese female university students and their associations with students' sexual risk-coping consciousness. We conducted a cross-sectional study using anonymous self-administered questionnaires.

Diagnosis of Acute Gastroenteritis with Immunochromatography and Effectiveness of Rotavirus Vaccine in a Japanese Clinic.

Despite the well known effectiveness of two licensed live attenuated oral rotavirus (RV)-vaccines, Rotarix and RotaTeq, constant monitoring of vaccine effectiveness (VE) is essential considering the evolving power and reassortment capability of RVs. In this study, we detected RV, norovirus (NV) and adenovirus (AV) infections using immunochromatography (IC)-based kits in children with acute gastroenteritis (AGE) who attended a pediatric clinic in Kiryu city, Gunma, Japan during June, 2014-September, 2018. VEs were determined using a test-negative study design.

Sexually transmitted infections and cervical cancer: Knowledge and prevention awareness among female university students in Japan.

Aim: To examine the possible association among knowledge regarding cervical cancer, its relationship with STIs and prevention awareness of STIs of female aged 20 years or older who were recommended regular screening for cervical cancer.

Design: A cross-sectional study using anonymous self-administered questionnaires.

Method: The subjects were 3rd- and 4th-year female university students.

Factors determining prenatal HIV testing for prevention of mother to child transmission in Dar Es Salaam, Tanzania.

Background: The objectives of the study were (i) to evaluate the Prevention of Mother to Child Transmission (PMTCT) services in Temeke district, Tanzania and (ii) to identify factors for non-acceptance of HIV testing among pregnant mothers in the area.

Methods: A structured questionnaire was used in face-to-face interviews at five health centers in the district. Univariate and multiple logistic regression analyses were used to assess the association of the refusal of human immunodeficiency virus (HIV) testing with risk factors.

Malnutrition improvement for infants under 18 months old of Dai minority in Luxi, China.

Background: Child malnutrition and thiamine deficiency remain a matter of public concern in Dai children under 5 years old in Southwest areas of China. The aim of the present study was to understand the status and correlates of malnutrition and thiamine deficiency in Dai children under 18 months old in Yunnan, China, and to explore an effective intervention for improving their nutritional status and decreasing the prevalence of malnutrition and thiamine deficiency in Dai children.

Methods: Well-trained investigators completed a baseline evaluation survey, including questionnaire survey by maternal interviews, child physical measurements, lab examination of thiamine, and group discussions in a cross-sectional study.

Specific factors for prenatal lead exposure in the border area of China.

The objectives of this study are to examine the prevalence of increased blood lead concentrations in mothers and their umbilical cords, and to identify risk factors for prenatal lead exposure in Kunming city, Yunnan province, China. The study was conducted at two obstetrics departments, and 100 peripartum women were enrolled. The mean blood lead concentrations of the mothers and the umbilical cords were 67.
