At a proteomic level, short term sleep deprivation is characterized by a higher expression of some proteins in the hippocampus and a lower abundance of other proteins in the adrenals (compared to normal sleep control). Altogether, this could indicate a general activation of a number of cellular mechanisms involved in the maintenance of wakefulness and in increased energy expenditure during sleep deprivation. These findings are relevant to suggested functions of sleep like energy repletion and the restoration of molecular stocks or a more global homeostasis of synaptic processes.
Introduction: At present, pregnant women in the U.S. are recommended to receive tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) and influenza vaccines. This study assessed maternal coverage of these 2 vaccinations. Methods: Data for this retrospective cohort study were extracted from 2 large administrative claims databases, the MarketScan Commercial and Multi-State Medicaid Databases, for 2009−2017 and analyzed in 2018. Women aged 15−44 years on the date of pregnancy end were included. Pregnancies with gestational age of less than 23 weeks were excluded from the Tdap vaccination endpoint owing to the optimal recommended gestational age for Tdap vaccination. Multivariable logistic regression models identified predictors of vaccination. Results: The Tdap vaccination subpopulation included 1,421,452 Commercial and 523,635 Medicaid pregnancies; the influenza vaccination subpopulation included 1,862,705 Commercial and 628,079 Medicaid pregnancies. There were marked increases in vaccination coverage from 2010 to 2017: from 1.0% to 56.3% (Commercial) and from 0.5% to 31.4% (Medicaid) for Tdap, and from 14.7% to 31.3% (Commercial) and from 9.7% to 17.5% (Medicaid) for influenza. The likelihood of Tdap/influenza vaccination increased significantly with receipt of the other vaccine and more pregnancy-related healthcare visits. Conclusions: Although maternal Tdap and influenza vaccination coverage increased substantially from 2010 to 2017 among large, geographically diverse U.S. cohorts, coverage remained suboptimal, potentially putting newborns at risk of pertussis and influenza. Strategies to increase maternal vaccination coverage could target women identified to have a reduced likelihood of vaccination: those who are younger, black, residing in rural areas, with multiple gestation, and a prepregnancy inpatient admission.
Despite vaccination recommendations, the burden of vaccine-preventable diseases remains high in older adults in the United States (US), contributing to substantial morbidity, mortality, and health care resource use and costs. To adequately plan for health care resource needs and to help inform vaccination policies, burden of disease projections that account for population aging over the coming decades are needed. As a first step, this exploratory study projects the burden of influenza, pertussis, herpes zoster, and pneumococcal disease in adults aged 50 y and older in the US, using a population-based modeling framework with separate decision trees for each vaccine-preventable disease. The model uses projected population estimates from the US Census Bureau to account for changes in the US population over time and then calculates expected numbers of cases and associated costs for each disease, keeping current estimates of age-specific disease incidence, vaccine coverage, and efficacy constant over time. This approach was used to focus the exploratory analysis on the burden of disease that may be expected due to population changes alone, assuming that all else remains unchanged. Due to population growth and the shifting age distribution over the next 30 y, the annual societal economic burden for the four vaccine-preventable diseases is projected to increase from approximately $35 billion to $49 billion, resulting in cumulative costs of approximately $1.3 trillion, as well as more than 1 million disease-related deaths. Given such notable burden, further efforts to increase vaccination coverage and effectiveness in older adults are needed.
for both groups. One-to-one propensity score matching (PSM) was used to compare health care costs and utilizations during the follow-up period between the HCV and comparison groups, adjusting for baseline demographic and clinical characteristics. Results: Eligible patients (N= 270,752) were identified for the HCV and comparison cohorts. After applying 1:1 PSM matching, a total of 107,953 patients were matched from each group and baseline characteristics were well-balanced. HCV patients were more likely to be hospitalized (15.90% vs. 3.19%, p< 0.01) and report more emergency room (20.36% vs. 8.17%, p< 0.01), physician office (99.18% vs. 61.06%, p< 0.01), outpatient (99.25% vs. 61.84%, p< 0.01) and pharmacy visits (91.11% vs. 63.13%, p< 0.01) which resulted in higher health care costs for inpatient
