In this population-based case-control study, 22,677 cases of rheumatoid arthritis are matched to 90,013 controls, with a median follow-up of 10 years before rheumatoid arthritis diagnosis. The odds of developing rheumatoid arthritis are 60% higher in those exposed to antibiotics than in those not exposed (OR 1.60; 95% CI 1.51-1.68). A dose- or frequency-dependent association is observed between the number of previous antibiotic prescriptions and rheumatoid arthritis. Antifungal (OR = 1.27; 95% CI 1.20-1.35) and antiviral (OR = 1.19; 95% CI 1.14-1.24) prescriptions are also associated with increased odds of rheumatoid arthritis.

In this meta-analysis of randomized clinical trials published published online June 19, 2019 in JAMA cardiology that included more than 83 000 participants, vitamin D supplementation was not associated with reduced risks of major adverse cardiovascular events, myocardial infarction, stroke, cardiovascular disease mortality, or all-cause mortality compared with placebo. These results suggest that vitamin D supplementation may not confer cardiovascular protection and may not be indicated for this purpose.

In a study from Denmark, total 2224 overweight individuals (1504 women, 720 men) followed a low-calorie diet (810 kcal/daily) for 8 weeks. The low-calorie diet induced different effects in women than in men, suggesting gender‐specific changes after weight loss. Body weight loss and reductions in a metabolic syndrome score, fat mass, and heart rate were more marked in men compared to women. However, reductions in HDL-cholesterol, hip circumference, lean body mass (or fat free mass), and pulse pressure were larger in women than in men.

Louisa Gibson and Melanie Porter from Australiaaimed to investigate whether drinking or smoking while breastfeeding lowers children’s cognitive scores. They analyzed the data obtained from 5107 Australian infants recruited in 2004 and assessed every 2 years. The authors observed that exposing infants to alcohol through breastmilk may cause dose-dependent reductions in their cognitive abilities. The reduction in cognitive abilities was observed at age 6 to 7 years but was not sustained at age 10 to 11 years. The authors stated that although the relationship is small, it may be clinically significant when mothers consume alcohol regularly or binge drink.

According to a meta-analysis performed by Clarke MA et al. 9% of women with postmenopausal bleeding have endometrial cancer. The authors analyzed data from 40790 unique patients in 129 studies published January 1, 1977, through January 31, 2017. They found that 90% of women with endometrial cancerhave postmenopausal bleeding; however, only 9% of women with postmenopausal bleeding were diagnosed with endometrial cancer.

In the Norwegian Mother and Child Cohort Study included a total of 50, 943 mothers recruited from 2002 to 2008 and their children, it was found that pregnant women with average (50–199 mg/day, 44%), high (≥200–299 mg/day, 7%) and very high (≥300 mg/day, 3%) caffeine intakes had an increased risk of their child experiencing excess growth in infancy compared with women with low caffeine intake (<50 mg/day, 46%). There was an association between in utero exposure to caffeine and higher risk of overweight at age 3 years and 5 years, this association persisted at 8 years, only for very high exposures. The researchers concluded that "any caffeine consumption during pregnancy is associated with a higher risk of excess infant growth and of childhood overweight, mainly at preschool ages."
