Morbid obesity, defined as bodymass index (BMI) ‡40 kg/m2, affects approximately 8% of United States adults and is a recognized risk factor for chronic kidney disease (CKD). We present the first focused biopsy-based study exploring the range of kidney diseases in this population. Among 3263 native kidney biopsies interpreted at Columbia University in 2017, we identified 248 biopsies from morb…
There is substantial variation in the timing of significant reproductive life events such as menarche and first sexual intercourse. Life history theory explains this variation as an adaptive response to an individual’s environment and it is important to examine how traits within life history strategies affect each other. Here we applied Mendelian randomization (MR) methods to investigate whet…
To assess the prospective associations of physical activity behaviors and screen time with early sexual intercourse initiation (i.e., before 15 years) in a large sample of adolescents
This study aimed to analyze the repercussion of first sexual intercourse on the number of pregnancies and partners of teenagers with obstetric history in Teresina (PI), Brazil. This is a cross-sectional study with 464 young women selected by accidental sampling who gave birth at 15-19 years of age in the first four months of 2006 in six maternity hospitals of the municipality
Among individuals with chronic kidney disease (CKD), poor self-reported health is associated with adverse outcomes including hospitalization and death. We sought to examine the association between health-related quality-of-life (HRQoL) and depressive symptoms in advanced CKD and subsequent access to the kidney transplant waiting list.
The prevalence of chronic kidney disease and its risk factors is increasing worldwide, and the rapid rise in global need for end-stage kidney disease care is a major challenge for health systems, particularly in low- and middle-income countries. Countries are responding to the challenge of end-stage kidney disease in different ways, with variable provision of the components of a kidney care str…
To help primary care providers, both family physicians and nurse practitioners, identify, detect, and manage patients with and at risk of chronic kidney disease (CKD), as well as outline criteria for appropriate referral to nephrology
Intrauterine growth restriction (IUGR), a condition that occurs due to various reasons, is an important cause of fetal and neonatal morbidity and mortality. It has been defined as a rate of fetal growth that is less than normal in light of the growth potential of that specific infant. Usually, IUGR and small for gestational age (SGA) are used interchangeably in literature, even though there exi…
Reduced fetal growth is seen in about 10% of the pregnancies but only a minority has a pathological background and is known as intrauterine growth restriction or fetal growth restriction (IUGR / FGR). Increased fetal and neonatal mortality and morbidity as well as adult pathologic conditions are often associated to IUGR. Risk factors for IUGR are easy to assess but have poor predictive value.…
Obstetric intervention originally consisted of extraction of the baby, usually by the breech, to save the mother’s life in obstructed labour. Forceps, introduced in the 17th century, were later refined by men-midwives like William Smellie. In Victorian times, Simpson championed chloroform anaesthesia, Lister pioneered antisepsis, and caesarean section was introduced. In 1935, however, Britai…
