TL;DR: Among extremely preterm infants born at US academic centers over the last 20 years, changes in maternal and infant care practices and modest reductions in several morbidities were observed, although bronchopulmonary dysplasia increased.
Abstract: Importance Extremely preterm infants contribute disproportionately to neonatal morbidity and mortality. Objective To review 20-year trends in maternal/neonatal care, complications, and mortality among extremely preterm infants born at Neonatal Research Network centers. Design, Setting, Participants Prospective registry of 34 636 infants, 22 to 28 weeks’ gestation, birth weight of 401 to 1500 g, and born at 26 network centers between 1993 and 2012. Exposures Extremely preterm birth. Main Outcomes and Measures Maternal/neonatal care, morbidities, and survival. Major morbidities, reported for infants who survived more than 12 hours, were severe necrotizing enterocolitis, infection, bronchopulmonary dysplasia, severe intracranial hemorrhage, cystic periventricular leukomalacia, and/or severe retinopathy of prematurity. Regression models assessed yearly changes and were adjusted for study center, race/ethnicity, gestational age, birth weight for gestational age, and sex. Results Use of antenatal corticosteroids increased from 1993 to 2012 (24% [348 of 1431 infants]) to 87% (1674 of 1919 infants];P Conclusions and Relevance Among extremely preterm infants born at US academic centers over the last 20 years, changes in maternal and infant care practices and modest reductions in several morbidities were observed, although bronchopulmonary dysplasia increased. Survival increased most markedly for infants born at 23 and 24 weeks’ gestation and survival without major morbidity increased for infants aged 25 to 28 weeks. These findings may be valuable in counseling families and developing novel interventions. Trial Registration clinicaltrials.gov Identifier:NCT00063063.

TL;DR: T-VEC is the first oncolytic immunotherapy to demonstrate therapeutic benefit against melanoma in a phase III clinical trial and represents a novel potential therapy for patients with metastatic melanoma.
Abstract: Purpose Talimogene laherparepvec (T-VEC) is a herpes simplex virus type 1‐derived oncolytic immunotherapy designed to selectively replicate within tumors and produce granulocyte macrophage colony-stimulating factor (GM-CSF) to enhance systemic antitumor immune responses. T-VEC was compared with GM-CSF in patients with unresected stage IIIB to IV melanoma in a randomized open-label phase III trial. Patients and Methods Patients with injectable melanoma that was not surgically resectable were randomly assigned at a two-to-one ratio to intralesional T-VEC or subcutaneous GM-CSF. The primary end point was durable response rate (DRR; objective response lasting continuously 6 months) per independent assessment. Key secondary end points included overall survival (OS) and overall response rate. Results Among 436 patients randomly assigned, DRR was significantly higher with T-VEC (16.3%; 95% CI, 12.1% to 20.5%) than GM-CSF (2.1%; 95% CI, 0% to 4.5%]; odds ratio, 8.9; P .001). Overall response rate was also higher in the T-VEC arm (26.4%; 95% CI, 21.4% to 31.5% v 5.7%; 95% CI, 1.9% to 9.5%). Median OS was 23.3 months (95% CI, 19.5 to 29.6 months) with T-VEC and 18.9 months (95% CI, 16.0 to 23.7 months) with GM-CSF (hazard ratio, 0.79; 95% CI, 0.62 to 1.00; P .051). T-VEC efficacy was most pronounced in patients with stage IIIB, IIIC, or IVM1a disease and in patients with treatment-naive disease. The most common adverse events (AEs) with T-VEC were fatigue, chills, and pyrexia. The only grade 3 or 4 AE occurring in 2% of T-VEC‐treated patients was cellulitis (2.1%). No fatal treatment-related AEs occurred.

TL;DR: The findings suggest that hypothalamic-pituitary-adrenal axis and autonomic nervous system hyperreactivity, presumably due to CRF hypersecretion, is a persistent consequence of childhood abuse that may contribute to the diathesis for adulthood psychopathological conditions.
Abstract: ContextEvidence suggests that early adverse experiences play a preeminent role
in development of mood and anxiety disorders and that corticotropin-releasing
factor (CRF) systems may mediate this association.ObjectiveTo determine whether early-life stress results in a persistent sensitization
of the hypothalamic-pituitary-adrenal axis to mild stress in adulthood, thereby
contributing to vulnerability to psychopathological conditions.Design and SettingProspective controlled study conducted from May 1997 to July 1999 at
the General Clinical Research Center of Emory University Hospital, Atlanta,
Ga.ParticipantsForty-nine healthy women aged 18 to 45 years with regular menses, with
no history of mania or psychosis, with no active substance abuse or eating
disorder within 6 months, and who were free of hormonal and psychotropic medications
were recruited into 4 study groups (n = 12 with no history of childhood abuse
or psychiatric disorder [controls]; n = 13 with diagnosis of current major
depression who were sexually or physically abused as children; n = 14 without
current major depression who were sexually or physically abused as children;
and n = 10 with diagnosis of current major depression and no history of childhood
abuse).Main Outcome MeasuresAdrenocorticotropic hormone (ACTH) and cortisol levels and heart rate
responses to a standardized psychosocial laboratory stressor compared among
the 4 study groups.ResultsWomen with a history of childhood abuse exhibited increased pituitary-adrenal
and autonomic responses to stress compared with controls. This effect was
particularly robust in women with current symptoms of depression and anxiety.
Women with a history of childhood abuse and a current major depression diagnosis
exhibited a more than 6-fold greater ACTH response to stress than age-matched
controls (net peak of 9.0 pmol/L [41.0 pg/mL]; 95% confidence interval [CI],
4.7-13.3 pmol/L [21.6-60.4 pg/mL]; vs net peak of 1.4 pmol/L [6.19 pg/mL];
95% CI, 0.2-2.5 pmol/L [1.0-11.4 pg/mL]; difference, 8.6 pmol/L [38.9 pg/mL];
95% CI, 4.6-12.6 pmol/L [20.8-57.1 pg/mL]; P<.001).ConclusionsOur findings suggest that hypothalamic-pituitary-adrenal axis and autonomic
nervous system hyperreactivity, presumably due to CRF hypersecretion, is a
persistent consequence of childhood abuse that may contribute to the diathesis
for adulthood psychopathological conditions. Furthermore, these results imply
a role for CRF receptor antagonists in the prevention and treatment of psychopathological
conditions related to early-life stress.

TL;DR: This work focuses on ROS at physiological levels and their central role in redox signalling via different post-translational modifications, denoted as ‘oxidative eustress’.
Abstract: 'Reactive oxygen species' (ROS) is an umbrella term for an array of derivatives of molecular oxygen that occur as a normal attribute of aerobic life. Elevated formation of the different ROS leads to molecular damage, denoted as 'oxidative distress'. Here we focus on ROS at physiological levels and their central role in redox signalling via different post-translational modifications, denoted as 'oxidative eustress'. Two species, hydrogen peroxide (H2O2) and the superoxide anion radical (O2·-), are key redox signalling agents generated under the control of growth factors and cytokines by more than 40 enzymes, prominently including NADPH oxidases and the mitochondrial electron transport chain. At the low physiological levels in the nanomolar range, H2O2 is the major agent signalling through specific protein targets, which engage in metabolic regulation and stress responses to support cellular adaptation to a changing environment and stress. In addition, several other reactive species are involved in redox signalling, for instance nitric oxide, hydrogen sulfide and oxidized lipids. Recent methodological advances permit the assessment of molecular interactions of specific ROS molecules with specific targets in redox signalling pathways. Accordingly, major advances have occurred in understanding the role of these oxidants in physiology and disease, including the nervous, cardiovascular and immune systems, skeletal muscle and metabolic regulation as well as ageing and cancer. In the past, unspecific elimination of ROS by use of low molecular mass antioxidant compounds was not successful in counteracting disease initiation and progression in clinical trials. However, controlling specific ROS-mediated signalling pathways by selective targeting offers a perspective for a future of more refined redox medicine. This includes enzymatic defence systems such as those controlled by the stress-response transcription factors NRF2 and nuclear factor-κB, the role of trace elements such as selenium, the use of redox drugs and the modulation of environmental factors collectively known as the exposome (for example, nutrition, lifestyle and irradiation).

TL;DR: Results support the emerging view that the gut microbiota contributes to metabolic disease and suggest that malfunction of the innate immune system may promote the development of metabolic syndrome.
Abstract: Metabolic syndrome is a group of obesity-related metabolic abnormalities that increase an individual's risk of developing type 2 diabetes and cardiovascular disease. Here, we show that mice genetically deficient in Toll-like receptor 5 (TLR5), a component of the innate immune system that is expressed in the gut mucosa and that helps defend against infection, exhibit hyperphagia and develop hallmark features of metabolic syndrome, including hyperlipidemia, hypertension, insulin resistance, and increased adiposity. These metabolic changes correlated with changes in the composition of the gut microbiota, and transfer of the gut microbiota from TLR5-deficient mice to wild-type germ-free mice conferred many features of metabolic syndrome to the recipients. Food restriction prevented obesity, but not insulin resistance, in the TLR5-deficient mice. These results support the emerging view that the gut microbiota contributes to metabolic disease and suggest that malfunction of the innate immune system may promote the development of metabolic syndrome.
