CLOSURE OF AUTOMOTIVE PLANTS ASSOCIATED WITH INCREASED DEATH FROM OPIOID OVERDOSE
Association Between Automotive Assembly Plant Closures and Opioid Overdose Mortality in the United States: A Difference-in-Differences Analysis
Venkataramani AS, Bair EF, O'Brien RL, Tsai AC.
Published in JAMA Internal Medicine on December 30, 2019

This research study found that after U.S. automotive assembly plans close, opioid overdose deaths increase in the county during the time period directly following the closure. Five years after a county experienced a plant closure, the rate of opioid overdose deaths in the affected county was greater by 85% compared with counties that did not experience a plant closure at the same time point. The largest increases in opioid overdose deaths were observed among non-Hispanic white men. Overall, the findings lend support to the view that the U.S. opioid overdose crisis may be associated, in part, with the same structural changes to the U.S. economy that since the 1980s have been responsible for worsening overall mortality among adults with less than a college degree.

MEDITERRANEAN DIET MAY LOWER RISK OF CROHN'S DISEASE
Adherence to a Mediterranean Diet is Associated with a Lower Risk of Later-Onset Crohn's Disease: Results From Two Large Prospective Cohort Studies
Khalili H, Håkansson N, Chan SS, Chen Y, Lochhead P [et al.], Wolk A.
Published in Gut on January 3, 2020

We used two large prospective cohorts to study the relationship between adherence to a Mediterranean diet and risk of Crohn’s disease and ulcerative colitis. Our data demonstrated that individuals that were most adherent to a Mediterranean diet had nearly a 60% reduction in risk of Crohn’s disease. We did not find a relationship between adherence to a Mediterranean diet and risk of ulcerative colitis. In our studied population, nearly 12% of cases of Crohn’s disease could have been prevented by following a Mediterranean diet. Our findings further highlight the importance of continued research focusing on the benefits of the Mediterranean diet among individuals at risk of developing Crohn’s disease.

PSYCHOSOCIAL INTERVENTION FOR CAREGIVERS OF STEM CELL TRANSPLANTEES
Multimodal Psychosocial Intervention for Family Caregivers of Patients Undergoing Hematopoietic Stem Cell Transplantation: A Randomized Clinical Trial
El-Jawahri A, Jacobs JM, Nelson AM, Traeger L, Greer JA [et al.], Temel JS.
Published in Cancer on January 3, 2020

Family and friend “caregivers” of patients undergoing stem cell transplant experience substantial burden and are at risk for depression, anxiety, and impaired quality of life (QOL). We developed and tested a six-session program (BMT-CARE), based in cognitive-behavioral therapy and delivered by psychologists and social workers, to teach coping skills and promote stress management. In a randomized controlled trial comparing BMT-CARE to usual care alone (one meeting with social work), caregivers assigned to the BMT-CARE program reported improved quality of life, coping skills, and confidence in caregiving, as well as reduced depression, anxiety, and caregiving burden. Caregivers can feasibly participate in BMT-CARE during the transplant process and, in doing so, may experience improved mood and QOL.

TMZ SENSITIVITY AND BASE EXCISION REPAIR IN GLIOBLASTOMA
Restoration of Temozolomide Sensitivity by Poly(ADP-Ribose) Polymerase Inhibitors in Mismatch Repair Deficient Glioblastoma is Independent of Base Excision Repair
Higuchi F, Nagashima H, Ning J, Koerner MVA, Wakimoto H, Cahill DP.
Published in Clinical Cancer Research on January 3, 2020

As malignant brain tumors, gliomas are most-often treated with the alkylating chemotherapy temozolomide (TMZ), which has been shown to extend survival. These tumors then frequently sustain mutations in mismatch repair (MMR) genes, most commonly MSH6, which make them resistant to this treatment. Here, we show that Poly(ADP-ribose) polymerase inhibitors (PARPi) can restore TMZ cytotoxicity even in MMR-deficient gliomas. Thus, PARPi restoration of TMZ chemosensitivity in MSH6-inactivated glioma represents a promising strategy to overcome acquired chemoresistance caused by MMR deficiency.

FLUOROMETRIC IMAGING FOR ARTHRITIS
Fluorometric Imaging for Early Diagnosis and Prognosis of Rheumatoid Arthritis
Lee JH, Jung SY, Park GK, Bao K, Hyun H [et al.], Choi HS.
Published in Advanced Science on January 7, 2020

Rheumatoid arthritis (RA) is a serious and progressive autoimmune disease that results in chronic inflammation with permanent disability of multiple joints. Molecular imaging in clinical practice has focused on the synovial joint tissue in the early stages of RA, since joint destruction is typically irreversible. In a recent Advanced Science paper, the Choi laboratory demonstrated for the first time accurate and quantitative imaging of RA using a fluorometric near-infrared imaging method. Combined with targeted contrast agents for bone and cartilage, authors could obtain separate, but simultaneous tissue-specific images of synovitis, cartilage destruction, and bone resorption. This strategy further allows quantitative bioimaging of articular tissue in response to the progressive course of RA.

CLINICAL OUTCOME PREDICTION IN DYSPNEA PATIENTS
Exercise Pulmonary Hypertension Predicts Clinical Outcomes in Patients with Dyspnea on Effort
Ho JE, Zern EK, Lau ES, Wooster L, Bailey CS [et al.], Lewis GD.
Published in Journal of the American College of Cardiology on January 7, 2020

Pulmonary hypertension is a highly morbid condition defined by elevation in the blood pressure in the lungs in a state of rest. Our study shows that in a broad population of individuals with shortness of breath during exertion, elevation in pulmonary pressures relative to blood flow in the lungs during exercise was closely associated with functional capacity and future cardiovascular event-free survival. Our work expands the definition of pulmonary hypertension and will hopefully catalyze future work to determine if exercise PH detection facilitates earlier administration of effective therapeutic interventions for his morbid condition.

HOST DEPENDENCY FACTORS OF FLU VIRUS
Genome-Wide CRISPR Screen Identifies Host Dependency Factors for Influenza A Virus Infection
Li B, Clohisey SM, Chia BS, Wang BS, Cui A [et al.], Hacohen N.
Published in Nature Communications on January 9, 2020

The influenza A virus (IAV) poses a major public health threat. Like most viruses, IAV has a relatively small genome of its own, and relies on its host’s machinery to replicate. Using CRISPR-Cas9 screens to systematically disable genes in human cells, a team led by Bo Li, Nir Hacohen, and colleagues has identified 121 host genes required for IAV to complete its life cycle — some of which could inform new therapeutic targets. The team further reports on associated mechanistic discoveries and a new analytical approach that incorporates their findings into the existing evidence base for influenza dependencies.

MECHANISMS OF MITOCHONDRIAL INNER-MEMBRANE FORMATION
Two Forms of Opa1 Cooperate to Complete Fusion of the Mitochondrial Inner-Membrane
Ge Y, Shi X, Boopathy S, McDonald J, Smith AW, Chao LH.
Published in eLife on January 10, 2020

Membrane compartments are special cellular ‘rooms’ for chemistry. Cells merge these 'rooms' in a reaction called membrane fusion. We studied this reaction in mitochondria, an important energetic and metabolic compartment. Neurodegenerative conditions, such as dominant optic atrophy, occur when membrane fusion does not work properly. Dr. Yifan Ge and our team studied this reaction using a reconstitution approach that allows for precise dissection of each step in a biochemical process. We discovered the efficiency and speed of the last step in fusion, pore opening, is controlled by relative amounts of two forms of the inner-membrane fusion protein, Opa1.

EXOME SEQUENCING FOR GENETIC SCHIZOPHRENIA RISK
Exome Sequencing in Schizophrenia-Affected Parent-Offspring Trios Reveals Risk Conferred by Protein-Coding de Novo Mutations
Howrigan DP, Rose SA, Samocha KE, Fromer M, Cerrato F [et al.], Neale BM.
Published in Nature Neuroscience on January 13, 2020

We evaluated DNA sequence from 2,772 parent-child trios to see if genes with a de novo mutation (i.e., not seen in parents) associate with a schizophrenia diagnosis in the child. Across all genes, the de novo mutation rate in cases is only slightly above the 2,216 control trios, and no single gene associates with schizophrenia risk. We do, however, find an increased proportion of de novo mutations in brain expressed and evolutionarily constrained genes. We highlight 16 genes with two or more protein-truncating mutations, a 3.15-fold higher rate than modeled expectations, indicating that larger studies will discover individual risk genes for schizophrenia.

PREGNANCY AND STROKE
Acute Stroke During Pregnancy and Puerperium
Elgendy IY, Gad MM, Mahmoud AN, Keeley EC, Pepine CJ.
Published in Journal of the American College of Cardiology on January 21, 2020

Acute stroke is a leading cause of death and disability worldwide. In the recent years, there has been an increase in the incidence of maternal mortality rates in the United States, and cardiovascular disease is a leading cause. This study evaluated the national trends of acute stroke among pregnant and post-partum women. We found that the rates of acute stroke during pregnancy have not changed or might be rising. We also found that the prevalence most risk factors for acute stroke have been increasing. Although, acute stroke is associated with high maternal mortality, reassuringly the rates of maternal mortality rates are decreasing.

BACTERIAL COMMUNITIES AND COLORECTAL CANCER
Association Between Sulfur-Metabolizing Bacterial Communities in Stool and Risk of Distal Colorectal Cancer in Men
Nguyen LH, Ma W, Wang DD, Cao Y, Mallick H [et al.], Chan AT.
Published in Gastroenterology on January 20, 2020

Evidence supports a critical relationship between foods we eat, gut bacteria, and how each influence colorectal cancer (CRC). Prior research has shown that both diet and the presence of select sulfur-metabolizing bacteria influence risk of CRC. Sulfur-metabolizing bacteria are microbes able to process dietary sulfur, generating carcinogenic hydrogen sulfide. We were able to show that a diet rich in processed meats and low in vegetables and legumes increase these bacteria in the gut, and in collaboration with a 25-person team from the Massachusetts General Hospital and the Harvard T.H. Chan School of Public Health, we linked long-term intake of this “sulfur microbial diet” to long-term risk of certain forms of CRC.

GUT MICROBES INFLUENCE EARLY LYMPHOCYTE DEVELOPMENT
Intestinal Microbes Influence Development of Thymic Lymphocytes in Early Life
Ennamorati M, Vasudevan C, Clerkin K, Halvorsen S, Verma S [et al.], Jain N.
Published in PNAS on January 21, 2020

Effective communication between mucosal immune cells and microbes is essential to build healthy microbial communities and promote mucosal immunity. In this study, we report that gut microbes and microbial antigens also regulate the development of innate lymphocytes in the thymus of infant mice. Migratory plasmacytoid dendritic cells are one conveyor of microbial information from the colon to developing thymic cells. Disrupting this “entero-thymic” communication in early life negatively impacts disease susceptibility in adulthood. Our studies identify an early life time window during which developing immune cells are receptive to microbial programming.

INHIBITING THROMBOSIS WHILE MAINTAINING HEMOSTASIS
Structure-Guided Design of Pure Orthosteric Inhibitors of aIIbß3 that Prevent Thrombosis but Preserve Hemostasis
Adair BD, Alonso JL, van Agthoven J, Hayes V, Ahn HS [et al.], Arnaout MA.
Published in Nature Communications on January 21, 2020

Current drugs targeting the platelet integrin receptor aIIbß3 are efficacious anti-thrombotics but are associated with life-threatening bleeding risk that is causally linked to paradoxical drug-induced activating shapeshifts in aIIbß3. Here, we developed high affinity peptide and small molecule antagonists that do not induce the pathologic shapeshifts in aIIbß3. These “pure” antagonists were as effective as existing anti-thrombotics in preventing thrombosis in animal models, predictive of clinical efficacy. In contrast to existing anti-thrombotics, however, the novel pure antagonists did not cause bleeding. These agents may provide safer alternatives for preventing blood clots in patients after heart attacks or during cardiac procedures.

IMPLICATIONS OF A HEPARIN SHORTAGE
Running Thin: Implications of a Heparin Shortage
McCarthy CP, Vaduganathan M, Solomon E, Sakhuja R, Piazza G [et al.], Patel NK.
Published in the Lancet on January 23, 2020

Heparin is the most widely used anticoagulant (blood thinner), often used to treat heart attacks and blood clots, as well as for various cardiac surgeries. Unfortunately manufacturing disturbances have resulted in unpredictable supply of heparin over the past year, with significant geographic variation across the United States. The global supply of heparin has been further threatened by an outbreak of African Swine Fever in China. It is clear we need more durable and reliable sources of heparin and other anticoagulants. In our viewpoint published in the Lancet, we discuss the role that clinicians, hospitals, manufacturers, and the community at large can play in ensuring a more reliable supply of anticoagulants in the future to ensure patient safety is preserved.

RISK OF SUICIDAL IDEATION IN PUBERTY-SUPPRESSED TRANS YOUTH
Pubertal Suppression for Transgender Youth and Risk of Suicidal Ideation
Turban JL, King D, Carswell JM, Keuroghlian AS.
Published in Pediatrics on January 23, 2020

Transgender adolescents often experience a worsening of dysphoria when they go through puberty due to their bodies developing physically in a way that is incongruent with their gender identity. Gonadotropin-releasing hormone analogs (puberty blockers) are often prescribed for these adolescents to ameliorate this distress. Analyzing data from a survey of over 20,000 transgender adults in the U.S., researchers found that those who accessed pubertal suppression had a lower odds of lifetime suicidal ideation when compared with transgender adults who desired pubertal suppression but did not access it (adjusted odds ratio = 0.3; 95% confidence interval = 0.2–0.6).
