The circadian clock synchronizes the body into 24-h cycles, thereby anticipating variations in tissue-specific diurnal tasks, such as response to increased cardiac metabolic demand during the active period of the day. As a result, blood pressure, heart rate, cardiac output, and occurrence of fatal cardiovascular events fluctuate in a diurnal manner. The heart contains different cell types that make up and reside in an environment of biochemical, mechanical, and topographical signaling. Cardiac architecture is essential for proper heart development as well as for maintenance of cell homeostasis and tissue repair. In this review, we describe the possibilities of studying circadian rhythmicity in the heart by using advanced in vitro systems that mimic the native cardiac 3D microenvironment which can be tuned in time and space. Harnessing the knowledge that originates from those in vitro models could significantly improve innovative cardiac modeling and regenerative strategies.Orientia tsutsugamushi (OT), the causative agent of the vector-borne Scrub typhus zoonotic disease in humans, is a unique microorganism that exists in the Asia-Pacific region since a long time. In spite of its occurrence, the organism had been neglected until recent years. Humans are the accidental dead-end hosts of O. tsutsugamushi and display manifestations which are both severe and misleading. Amenamevir cell line The vast antigenic diversity of OT and non-pathognomic symptoms of Scrub typhus, create hurdles in the clinical management of the disease and impede the OT-research. Many countries in the Asia-Pacific region have reported the resurgence of OT- infections and have raised concerns for its expanding distribution. This has triggered the development of advanced techniques for diagnosis and research on exploring a successful vaccine candidate to reduce the burden of the disease. Thus, the aim of this systematic review is to provide an update on the recent advances in the OT-research and highlight the key areas that have remained obscure and demand attention.
Trauma to the chest wall is one of the most common injuries suffered. Knowing whether there are regular and reproducible changes in frequency or severity of certain injury types may help resource allocation and improve prevention efforts or outcomes; however, no prior studies have evaluated seasonal variation in chest wall injuries (CWIs). We aimed to determine if CWIs vary annually in a consistent distinct temporal variation.
Using an established traumatic blunt CWI database at a single urban level 1 trauma center, patients with a moderate-to-severe (chest wall Abbreviated Injury Score (AIS) ≥2) CWI were reviewed. A subpopulation of predominant chest wall injury (pCWI) was defined as those with a chest wall AIS ≥3 and no other anatomic region having a higher AIS. Demographics, injury patterns, mechanisms of injury, and AIS were collected in addition to date of injury over a 4-y period. Data were analyzed using descriptive statistics as well as Poisson time-series regression for periodicity. Seasonal compries by mechanism revealed a concomitant increase in motorcycle collisions during this period.
There appears to be a significant seasonal variation in the overall incidence of CWI as well as severe pCWI, with a high-volume injury season in summer months (June-October) and low-volume season in winter (December-April). Motorcycle accidents were the major blunt injury mechanism that changed with this seasonality. These findings may help guide resource utilization and injury prevention.

Length of stay (LOS) is an important measure of quality; however, estimating LOS for rare populations such as gastroschisis is problematic. Our objective was to identify explanatory variables for LOS and build a model to estimate LOS in neonates with simple gastroschisis.
In 73 neonates with simple gastroschisis (47% female, 67% White), statistical correlations for 31 potential explanatory variables for LOS were evaluated using multivariate linear regression. Poisson regression was used to estimate LOS in predetermined subpopulations, and a life table model was developed to estimate LOS for simple gastroschisis.
Female sex (-2.4d), "time to silo placement" (0.9d), total parenteral nutrition days (0.6d), need for any nasogastric feedings (11.4d) and at discharge (-7d), "feeding tolerance" (0.4d), days to first postoperative stool (-0.3d), and human milk exposure (-3.4d) associated with LOS in simple gastroschisis. Estimated LOS for preterm neonates was longer than term infants (5.4 versus 4.6wk) but similar for estimates based on sex and race. Based on these associations, we estimate that >50% of neonates with simple gastroschisis will be discharged by hospital day35.
We identified several associations that explained variations in LOS and developed a novel model to estimate LOS in simple gastroschisis, which may be applied to other rare populations.

Tracheostomy is commonly used for managing the airway of trauma patients. Complications are common and result in increased length of stays and treatment cost. The aim of this study is to evaluate whether the utilization of skin sutures or foam barrier dressings affect tracheostomy complication rates.
This is a single-center retrospective review of patients who underwent a tracheostomy by the trauma service between January 2014 and December 2017. Collected variables included demographics, patient history, treatment variables, complications, and outcomes. Univariate and multivariate analyses were constructed to identify significant predictors for the development of complications.
A total of 268 patients were included. The median age was 43.5y, 221 (82.5%) patients were men, and the median BMI was 28 (IQR 24.6, 32.2). Most (87.3%) of the procedures were performed in the operating room and 82.5% were open. Skin sutures were used in 46.3% and 53.4% had a foam barrier dressing placed.
