Abnormal Uterine Bleeding Among Rural Adolescent Schoolgirls: A Cross-Sectional Study.

: The International Federation of Gynecology and Obstetrics (FIGO) and the American College of Obstetricians and Gynecologists (ACOG) define abnormal uterine bleeding (AUB) as "bleeding from the uterus that is abnormal in regularity, volume, frequency, or duration and occurs in the absence of pregnancy". The impact of AUB on the physical and psychosocial well-being of adolescent girls can be significant. In this study, we aim to investigate the menstrual cycle characteristics in adolescent Sudanese schoolgirls and the prevalence of abnormal uterine bleeding (AUB) and its associated factors.

Association of vitamin D deficiency and insufficiency with uncontrolled type 1 diabetes Mellitus among Saudi pediatric patients; a hospital-based retrospective study.

Background: The association between 25-hydroxy-vitamin D [25(OH)D] levels and glycemic control in pediatric patients with type 1 diabetes mellitus (T1DM) is unclear. In this study, we aimed to investigate the association between 25(OH)D levels and glycemic control in Saudi pediatric patients' with T1DM in a region that is sunny year-round.

Materials And Methods: A retrospective study was conducted in the Pediatric Department of King Saud Hospital in Unaizah, Saudi Arabia.

The accuracy of anthropometric indices in detecting hypertension in Sudanese adults: a cross-sectional study.

Background: Hypertension is an increasing health problem; hence, efforts have been made to promote the disease's early detection and modify prognoses. We aim to evaluate the accuracy of body mass index (BMI), waist circumference (WC), and waist-height ratio (WHtR) in detecting hypertension among adults in Northern Sudan.

Methods: Adults were recruited for a multi-stage sampling survey in Northern Sudan.

Familiarity of an environment prevents song suppression in isolated zebra finches.

Despite the wide use of zebra finches as an animal model to study vocal learning and production, little is known about impacts on their welfare caused by routine experimental manipulations such as changing their social context. Here we conduct a post-hoc analysis of singing rate, an indicator of positive welfare, to gain insights into stress caused by social isolation, a common experimental manipulation. We find that isolation in an unfamiliar environment reduces singing rate for several days, indicating the presence of an acute stressor.
