REVIEW
Qiaohong Wang, Xia Wu
PD-1/PD-L1 blockade appears to be a very promising immunotherapy with significant clinical benefits and durable responses in multiple tumor types. However, the effectual clinical benefits of PD-1/PD-L1 blockade are hampered by a high rate of primary resistance, where patients do not respond to PD-1/PD-L1 blockade initially. And more distressingly, most patients eventually develop acquired resistance after an initial response to PD-1/PD-L1 blockade. The mechanisms underlying primary and acquired resistance to PD-1/PD-L1 blockade have remained ambiguous...

Increasing evidence from experimental and non-experimental research has shown that children residing in disadvantaged neighborhoods exhibit greater levels of internalizing and externalizing behaviors, above and beyond individual characteristics, and family or school contexts. Using the ECLS-K, a nationally representative, longitudinal survey of U.S. school children, this study examined direct neighborhood effects on internalizing (N = 14,870; N = 10,610) and externalizing (N = 14,960; N = 10,730) behaviors at the beginning and end of elementary school...

BACKGROUND: Adverse childhood experiences (ACE) increase the risk to develop major depressive disorder (MDD) and obesity or metabolic syndrome in adulthood. In addition, ACE may be associated with an exaggerated endocrine response to stress, which, in turn, may lead to enhanced food intake resulting in obesity and metabolic problems. METHODS: We systematically examined the stress response and consecutive food intake in 32 women with MDD and ACE as determined by a clinical interview (Early Trauma Inventory), 52 women with MDD without ACE, 22 women with ACE but no current or lifetime MDD and 37 healthy women without either MDD or ACE...

The Epic electronic health record (EHR) platform supports structured data entry systems (SDES), which allow developers, with input from users, to create highly customized patient-record templates in order to maximize data completeness and to standardize structure. There are many potential advantages of using discrete data fields in the EHR to capture data for secondary analysis and epidemiological research, but direct data acquisition from clinicians remains one of the largest obstacles to leveraging the EHR for secondary use...

Huntington's disease (HD) is an autosomal dominantly inherited neurodegenerative disease characterized by progressive motor, behavioral, and cognitive decline, ending in death. Despite the discovery of the underlying genetic mutation more than 20 years ago, treatment remains focused on symptomatic management. Chorea, the most recognizable symptom, responds to medication that reduces dopaminergic neurotransmission. Psychiatric symptoms such as depression and anxiety may also respond well to symptomatic therapies...

Tobacco use is a significant health problem in Yemen and worldwide. Dental practitioners can play a pivotal role in educating their patients on the risk of smoking and motivating them to quit. This study aimed to assess the attitudes towards and practices of tobacco cessation counseling (TCC) among Yemeni dental professionals and to evaluate whether such attitudes and practices are associated with gender, smoking status, and years since graduation. In this cross-sectional study, a self-administered questionnaire containing questions regarding the practice and attitudes towards TCC in dental clinic was used...

Subsurface oxygen is known to form in transition metals, and is thought to be an important aspect of their ability to catalyze chemical reactions. The formation of subsurface oxygen is not, however, equivalent across all catalytically relevant metals. As a result, it is difficult to predict the stability and ease of the formation of subsurface oxygen in metals, as well as how the absorbed oxygen affects the chemical and physical properties of the metal. In comparing how a stepped platinum surface, Pt(5 5 3), responds to exposure to gas-phase oxygen atoms under ultra-high vacuum conditions to planar Rh(1 1 1), we are able to determine what role, if any, steps have on the capacity of a metal for subsurface oxygen formation...

BACKGROUND: Recovery high schools (RHS) vary in organization and operating philosophy, but are designed to support the unique needs of students struggling with substance use disorders (SUD). Previous research on youth risk taking behaviors suggests emotion regulation is a key predictor of outcomes. Specifically, the ability to respond in adaptive rather than maladaptive ways is often associated with challenges of impulsivity, poor distress tolerance, and adolescent substance use. OBJECTIVES: The current study considers data from RHS students in order to answer research questions concerning impulsivity and emotion regulation of youth working to change their risk trajectories in comparison to group of typically developing youth...

Every spacecraft sent to Mars is allowed to land viable microbial bioburden, including hardy endospore-forming bacteria resistant to environmental extremes. Earth's stratosphere is severely cold, dry, irradiated, and oligotrophic; it can be used as a stand-in location for predicting how stowaway microbes might respond to the martian surface. We launched E-MIST, a high-altitude NASA balloon payload on 10 October 2015 carrying known quantities of viable Bacillus pumilus SAFR-032 (4.07 × 10(7) spores per sample), a radiation-tolerant strain collected from a spacecraft assembly facility...

Macrophages comprise a highly diverse cell population expressing a continuum of biologic activities dictated by exposure to a plethora of inflammatory cues. Moreover, in contrast to most other hematopoietic populations, macrophages can arise from multiple sites-namely, the bone marrow or yolk sac, adding to the complexity of macrophage biology during health and disease. Nonetheless, it is this very type of diversity that is indispensable for macrophages to respond effectively to pathologic insults. Most of the interest in macrophage biology has been devoted to bone marrow-derived populations, but it is now becoming clearer that tissue-resident populations, which arise from distinct hematopoietic compartments, serve critical roles in host defense, including protection against neoplastic disease...

The thymus is essential for proper development and maintenance of a T-cell repertoire that can respond to newly encountered antigens, but its function can be adversely affected by internal factors such as pregnancy and normal aging or by external stimuli such as stress, infection, chemotherapy and ionizing radiation. We have utilized a unique archive of thymus tissues, obtained from 165 individuals, exposed to the 1945 atomic bomb blast in Hiroshima, to study the long-term effects of receiving up to ∼3 Gy dose of ionizing radiation on human thymus function...

The psychosocial impact of hemophilia on activities was recently investigated in the Hemophilia Experiences, Results and Opportunities (HERO) study (675 people with hemophilia and 561 caregivers of children with hemophilia in 10 countries). The impact of hemophilia B may not be accurately reflected in the HERO results, as ~75% of respondents described issues affecting males with hemophilia A. To address the needs of this population, the Bridging Hemophilia B Experiences, Results and Opportunities Into Solutions (B-HERO-S) was developed as a pilot study in the United States in collaboration with the hemophilia community...

INTRODUCTION: Obstructive defecation (OD) has a high prevalence and disease impact, however patients often experience suboptimal management. This problem reflects the complex pathophysiology of OD, as well as health service delivery factors. This study aimed to identify factors acting as a barrier to effective OD management as perceived by specialist colorectal surgeons treating this disorder. METHOD: A postal questionnaire was administered to a bi-national sampling of colorectal specialists in Australia and New Zealand who were registered with their specialty society...

Individuals with autism-spectrum disorder (ASD) exhibit impairments in response to others' pain. Evidence suggests that features of autism are not restricted to individuals with ASD, and that autistic traits vary throughout the general population. To investigate the association between autistic traits and the responses to others' pain in typically developing adults, we employed the Autism-Spectrum Quotient (AQ) to quantify autistic traits in a group of 1670 healthy adults and explored whether 60 participants (30 males and 30 females) with 10% highest AQ scores (High-AQ) would exhibit difficulties in the responses to others' pain relative to 60 participants (30 males and 30 females) with 10% lowest AQ scores (Low-AQ)...

AIMS: Type 2 diabetes is associated with cardiovascular complications. It is largely unknown which patients have poor treatment response and high complication risk; biomarkers are studied for this purpose. The aim of the study was to investigate the association between clinical factors such as HbA1c, level of biomarkers (C-peptide, copeptin) at diagnosis and changes in HbA1c, blood pressure or body mass index (BMI) after five years. METHODS: Clinical data and blood samples from 460 newly diagnosed type 2 diabetes patients from the Skaraborg diabetes register (SDR) at diagnosis and after 5years and were analyzed with linear and logistic regressions...

Treatment of unipolar depression with currently available antidepressants is still unsatisfactory. Augmentation with lithium or second generation antipsychotics is an established practice in non-responders to antidepressant monotherapy, but is also associated with a substantial non-response rate and with non-tolerance. Based on a systematic review of the literature, including meta-analyses, randomized controlled trials (RCTs), non-randomized comparative studies and case studies, off-label augmentation agents (administered in addition to an antidepressant, without FDA approval for treatment of MDD) were identified and evaluated regarding their efficacy using levels of evidence...

Nicotine use and dependence is very high in patients with schizophrenia. One possible reason is that altered dopamine or glutamate activity in schizophrenia enhances the reinforcing effectiveness of nicotine. We used animal models to test the hypothesis that a hyperdopaminergic state (induced by repeated intermittent injections of amphetamine) or altered glutamate function (subchronic injection of phencyclidine, PCP) facilitates spontaneous acquisition of nicotine self-administration in rats. In Experiment 1 animals in an amphetamine-induced sensitized state (AISS) did not differ from saline-injected controls in their acquisition and maintenance of nicotine self-administration...

Factors that affect the direction of root growth in response to environmental signals influence crop productivity. We analyzed the root tropic responses of thioredoxin (trxs), thigmotropic (wav2-1), and hydrotropic (ahr1 and nhr1) Arabidopsis thaliana mutants treated with low concentrations of paraquat (PQ), which induces mild oxidative stress, and established a new method for evaluating root waviness (root bending effort, RBE). This method estimates root bending by measuring and summing local curvature over the whole length of the root, regardless of the asymmetry of the wavy pattern under thigmostimulation...

CONTEXT: Problems with sexual function can have a detrimental effect on quality of life. Symptomatic heart failure has been associated with problems with sexual function, although the majority of reports are focused on men and erectile dysfunction. Understanding women's perception of and gender differences in problems with sexual function in heart failure could yield new insights. OBJECTIVES: To determine the gender differences in reporting and bothersomeness of problems with sexual function, defined as sexual interest or activity...

In a fluctuating environment, the optimal level of exploratory behavior depends on the proportion of current risks and benefits. The exploratory behavior is, therefore, often subjected to heterogenous selection. In populations of commensal rodents living in close proximity of humans, this pressure is further increased by pest management. We hypothesize that the black rat (Rattus rattus) responds to this pressure by either high behavioral flexibility or by development of personality types. The aim of this study was to analyze exploratory behavior and boldness of wild black rats and its changes over time to determine whether exploratory behavior is a personality trait in black rats...
