Background:Physiological and biochemical processes across tissues of the body are regulated in response to the high demands of intense physical activity in several occupations,such as firefighting,law enforcement,military,and sports.A better understanding of such processes can ultimately help improve human performance and prevent illnesses in the work ***:To study regulatory processes in intense physical activity simulating real-life conditions,we performed a multi-omics analysis of 3 biofluids(blood plasma,urine,and saliva)collected from 11 wildland firefighters before and after a 45 min,intense exercise *** profiles ***-exercise were compared by Student’s t-test followed by pathway analysis and comparison between the different omics ***:Our multi-omics analysis identified and quantified 3835 proteins,730 lipids and 182 metabolites combining the 3 different types of *** blood plasma analysis revealed signatures of tissue damage and acute repair response accompanied by enhanced carbon metabolism to meet energy *** urine analysis showed a strong,concomitant regulation of 6 out of 8 identified proteins from the renin-angiotensin system supporting increased excretion of catabolites,reabsorption of nutrients and maintenance of fluid *** saliva,we observed a decrease in 3 pro-inflammatory cytokines and an increase in 8 antimicrobial peptides.A systematic literature review identified 6 papers that support an altered susceptibility to respiratory ***:This study shows simultaneous regulatory signatures in biofluids indicative of homeostatic maintenance during intense physical activity with possible effects on increased infection susceptibility,suggesting that caution against respiratory diseases could benefit workers on highly physical demanding jobs.

Optimizing outcomes for patients with gastric cancer peritoneal carcinomatosis

World Journal of Gastrointestinal Oncology 2018年第10期10卷 282-289页

作者： jennifer L Leiting Travis e Grotz Division of Hepatobiliary and Pancreas Surgery Mayo Clinic

Peritoneal carcinomatosis (PC) from gastric cancer has traditionally been considered a terminal progression of the disease and is associated with poor survival out-comes. Positive peritoneal cytology similarly worsens the survival of patients with gastric cancer and treatment options for these patients have been limited. Recent ad-vances in multimodality treatment regimens have led to innovative ways to care for and treat patients with this disease burden. One of these advances has been to use neoadjuvant therapy to try and convert patients with positivecytologyorlow-volume PC to negative cytolo-gy with no evidence of active peritoneal *** strategies include the use of neoadjuvant systemic chemotherapy alone,using neoadjuvant laparoscopic heated intraper itoneal chemotherapy(NLHIPeC)after systemic chemotherapy,or using neoadjuvant intra-peritoneal and systemic chemother apy(NIPS)in a bi-dir ectional manner. For patients with higher volume PC,cytoreductive surgery (CRS) and hyperthermic intrape-ritoneal chemotherapy(HIPeC)have been mainstays of treatment. When used together, CRS and HIPeC can improve overall outcomes in properly selected patients,but overall survival outcomes remain unacceptably *** extent of peritoneal disease, commonly measured by the peritoneal carcinomatosis index (PCI), and the com-pleteness of cytor eduction,has been shown to greatly impact outcomes in patients undergoing CRS and *** uses of NLHIPeC and NLHIPeC plus NIPS have both been shown to decrease the PCI and thus increase the opportunity for complete cytoreduction. Newer therapies like pressurized intraperitoneal aerosol chemother apy and immunotherapy, such as catumaxomab, along with improved systemic chemotherapeutic regimens, are being explored with great *** is exciting progress being made in the management of PC from gastric can-cer and its’ treatment is no longer futile.

Background High deductible health plans(HDHPs)are associated with the avoidance of both necessary and unnecessary *** hernia repair(UHR)is a procedure that is frequently unnecessarily performed in young children,contrary to best practice *** hypothesized that children with HDHPs,as compared with other types of commercial health plans,are less likely to undergo UHR before 4 years of age but are also more likely to have UHR delayed beyond 5 years of *** Children aged 0-18 years old residing in metropolitan statistical areas(MSAs)who underwent UHR in 2012-2019 were identified in the IBM Marketscan Commercial Claims and encounters Database.A quasi-experimental study design using MSA/year-level HDHP prevalence among children as an instrumental variable was employed to account for selection bias in HDHP ***-stage least squares regression modeling was used to evaluate the association between HDHP coverage and age at *** A total of 8601 children were included(median age 5 years,IQR 3-7).Univariable analysis revealed no differences between the HDHP and non-HDHP groups in the likelihood of UHR being performed before 4 years of age(27.7%vs 28.7%,p=0.37)or after 5 years of age(39.8%vs 38.9%,p=0.52).Geographical region,metropolitan area size,and year were associated with HDHP *** variable analysis demonstrated no association between HDHP coverage and undergoing UHR atears of age(p=0.76)or>5 years of age(p=0.87).Conclusions HDHP coverage is not associated with age at pediatric *** studies should investigate other means by which UHRs in young children can be avoided.
