Human milk is associated with positive short- and long-term health outcomes. Women's choice to breastfeed is influenced by personal, social, health, and economic factors. The COVID-19 pandemic impacted health care delivery, non-emergent health care services, and family lifestyles, primarily in the early months of 2020. The aim of this study was to determine if breastfeeding initiation rates differed during a global pandemic among women in the military health care system. ⋯ Overall breastfeeding initiation rates did not differ during the COVID-19 pandemic when rates in 2020 were compared to those in the year prior. Race, birth method, parity, and gestational age were associated with breastfeeding initiation rates in women cared for at military centers.

Post-traumatic stress disorder (PTSD) is a prevalent health condition among members of the military. Although the efficacy of pharmacological and psychiatric interventions for PTSD has been well studied, there are limited data on the effects of omega-3 (n-3) polyunsaturated fatty acid (PUFA) interventions on PTSD. The use of PUFAs shows promise because of their neuroprotective effects. Thus, this systematic review will synthesize the current state of the evidence regarding the effectiveness of PUFA treatment for PTSD. ⋯ The results from this systematic review suggest that more evidence is needed before making any recommendations for the clinical use of dietary PUFAs in the management of PTSD symptoms.

Hemorrhage is assessed, at least in part, via hematocrit testing. To differentiate unexpected drops in hematocrit because of ongoing hemorrhage versus expected drops as a result of known hemorrhage and intravenous fluid administration, we model expected post-operative hematocrit values accounting for fluid balance and intraoperative estimated blood loss (EBL) among patients without substantial post-operative bleeding. ⋯ Patient-specific data, including fluid received since the time of initial hemorrhage, can aid in estimating expected post-hemorrhage hematocrit values, and thus in assessing for the ongoing hemorrhage.

Foot-borne soldiers sometimes carry out nighttime operations. It has previously been reported an elevated metabolic demand and impaired walking economy during outdoor walking on a gravel road in darkness wearing night vision goggles (NVG), compared with wearing a headlamp. The aim of the present study was to evaluate the effect of wearing NVG while walking in a hilly forest terrain and compare the results between experienced and inexperienced NVG users. ⋯ Despite that foveal vision using NVG is adequate, it appears that the mechanical efficiency during nighttime walking in hilly terrain was markedly lower while wearing NVG than with full vision, regardless of whether the soldier was an experienced or inexperienced NVG user. Moreover, the walking economy was even more affected when adding the 25-kg extra weight. It is probable that the deteriorated mechanical efficiency was partly due to the shorter step length in all three conditions with limited vision.

Excess thyroid hormone is a well-documented risk factor for the development of atrial fibrillation (AF). The purpose of the study is to assess incidence of AF in patients taking levothyroxine for hypothyroidism and correlate it with biochemical thyroid function. ⋯ In hypothyroid patients treated with levothyroxine, higher circulating fT4 levels are associated with increased risk of incident AF. There is no association of serum TSH with risk of AF. In patients at risk for AF, consideration should be given to avoiding fT4 levels in the highest quartile.
