The Effects of Vitamin D Supplementation and 25-Hydroxyvitamin D Levels on the Risk of Myocardial Infarction and Mortality.

Objective: The aim of the study was to examine the effects of the vitamin D (Vit-D) treatment and nontreatment on Vit-D-deficient patients without a prior history of myocardial infarction (MI).

Materials And Methods: This was a retrospective, observational, nested case-control study of patients (N = 20 025) with low 25-hydroxyvitamin D ([25-OH]D) levels (<20 ng/mL) who received care at the Veterans Health Administration from 1999 to 2018. Patients were divided into 3 groups: Group A (untreated, levels ≤20 ng/mL), Group B (treated, levels 21-29 ng/mL), and Group C (treated, levels ≥30 ng/mL).

Relation of Testosterone Normalization to Mortality and Myocardial Infarction in Men With Previous Myocardial Infarction.

The effect of normalization of serum testosterone levels with testosterone replacement therapy (TRT) in patients with a history of myocardial infarction (MI) is unknown. The objective of this study was to determine the incidence of recurrent MI and all-cause mortality in subjects with a history of MI and low total testosterone (TT) with and without TRT. We retrospectively examined 1,470 men with documented low TT levels and previous MI, categorized into Gp1: TRT with normalization of TT levels (n = 755) Gp2: TRT without normalization of TT levels (n = 542), and Gp3: no TRT (n = 173).

Normalization of Testosterone Levels After Testosterone Replacement Therapy Is Not Associated With Reduced Myocardial Infarction in Smokers.

Objective: To examine the effect of cigarette smoking (CS) status and total testosterone (TT) levels after testosterone replacement therapy (TRT) on all-cause mortality, myocardial infarction (MI), and stroke in male smokers and nonsmokers without history of MI and stroke.

Participants And Methods: Data from 18,055 males with known CS status and low TT levels who received TRT at the Veterans Health Administration between December 1, 1999, and May 31, 2014, were grouped into (1) current smokers with normalized TT, (2) current smokers with nonnormalized TT, (3) nonsmokers with normalized TT, and (4) nonsmokers with nonnormalized TT. Combined effect of CS status and TT level normalization after TRT on all-cause mortality, MI, and stroke was compared using propensity score-weighted Cox proportional hazard models.

Normalization of Testosterone Levels After Testosterone Replacement Therapy Is Associated With Decreased Incidence of Atrial Fibrillation.

Background: Atrial fibrillation (AF) is the most common cardiac dysrhythmia associated with significant morbidity and mortality. Several small studies have reported that low serum total testosterone (TT) levels were associated with a higher incidence of AF. In contrast, it is also reported that anabolic steroid use is associated with an increase in the risk of AF.

Association Between Testosterone Replacement Therapy and the Incidence of DVT and Pulmonary Embolism: A Retrospective Cohort Study of the Veterans Administration Database.

Background: Testosterone replacement therapy (TRT) prescriptions have increased several-fold in the last decade. There have been concerns regarding a possible increased incidence of DVT and pulmonary embolism (PE) with TRT. Few data support the association between TRT and DVT/PE.

Normalization of testosterone level is associated with reduced incidence of myocardial infarction and mortality in men.

Aims: There is a significant uncertainty regarding the effect of testosterone replacement therapy (TRT) on cardiovascular (CV) outcomes including myocardial infarction (MI) and stroke. The aim of this study was to examine the relationship between normalization of total testosterone (TT) after TRT and CV events as well as all-cause mortality in patients without previous history of MI and stroke.

Methods And Results: We retrospectively examined 83 010 male veterans with documented low TT levels.

Identifying pregnant women who would adhere to food taboos in a rural community: a community-based study.

Poor maternal nutrition, especially in rural settings, adversely affects pregnancy and birth outcomes. In many local communities, pregnant women have food taboos with consequent depletion of vital nutrients. To facilitate early identification and prompt counseling, this study aimed at describing pregnant women who are likely to keep food taboos.
