RBM3 promotes neurogenesis in a niche-dependent manner via IMP2-IGF2 signaling pathway after hypoxic-ischemic brain injury

Hypoxic ischemia (HI) is an acute brain threat across all age groups. Therapeutic hypothermia ameliorates resulting injury in neonates but its side effects prevent routine use in adults. Hypothermia up-regulates a small protein subset that includes RNA-binding motif protein 3 (RBM3), which is neuroprotective under stressful conditions. Here we show how RBM3 stimulates neuronal differentiation and inhibits HI-induced apoptosis in the two areas of persistent adult neurogenesis, the subventricular zone (SVZ) and the subgranular zone (SGZ), while promoting neural stem/progenitor cell (NSPC) proliferation after HI injury only in the SGZ. RBM3 interacts with IGF2 mRNA binding protein 2 (IMP2), elevates its expression and thereby stimulates IGF2 release in SGZ but not SVZ-NSPCs. In summary, we describe niche-dependent regulation of neurogenesis after adult HI injury via the novel RBM3-IMP2-IGF2 signaling pathway.

Assessment of sex-specific differences in adverse events following immunization reporting in Ontario, 2012–15

We assessed sex-specific trends within passive vaccine safety surveillance in Ontario, Canada. AEFIs reported following vaccines administered between 2012 and 2015 were included. There were 2466 AEFI reports; 66.2% were female. Annualized reporting rates were 5.9 and 3.1 per 100,000 population, for females and males respectively. The female:male reporting rate ratio (RRR) was 1.9. Sex-specific differences by age group were greatest in adults 18–64years (RRR 6.3); whereas there were no differences in children <10years. Vaccine-specific RRRs were highest for vaccines recommended for routine use in adults or high risk populations. All event categories were female-predominant. The highest event-specific RRRs were for oculorespiratory syndrome (5.1), anaesthesia/paraesthesia (4.6) and anaphylaxis (3.0). Serious AEFIs (n=113) were more evenly distributed (57.5% female, RRR 1.3) than non-serious (66.6% female, RRR 1.9). AEFI reporting among females was consistently elevated within the passive surveillance system in Ontario. Further study of the relationship between sex/gender and AEFI reporting is needed.

Evaluating the Psychometric Properties and Responsiveness to Change of 3 Depression Measures in a Sample of Persons With Traumatic Spinal Cord Injury and Major Depressive Disorder

ObjectivesTo compare the measurement properties and responsiveness to change of the Patient Health Questionnaire-9 (PHQ-9), the Hopkins Symptom Checklist-20 (HSCL-20), and the Hamilton Depression Rating Scale (HAM-D) in people with spinal cord injury (SCI) diagnosed with major depressive disorder (MDD). DesignSecondary analysis of depression symptoms measured at 6 occasions over 12 weeks as part of a randomized controlled trial of venlafaxine XR for MDD in persons with SCI. SettingOutpatient and community settings. ParticipantsIndividuals (N=133) consented and completed the drug trial. Eligibility criteria were age at least 18 years, traumatic SCI, and diagnosis of MDD. InterventionsVenlafaxine XR. Main Outcome MeasuresPatients completed the PHQ-9 and the HSCL-20 depression scales; clinical investigators completed the HAM-D and the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-IV) Dissociative Disorders, which was used as a diagnostic criterion measure. ResultsAll 3 instruments were improved with rating scale analysis. The HSCL-20 and the HAM-D contained items that misfit the underlying construct and that correlated weakly with the total scores. Removing these items improved the internal consistency, with floor effects increasing slightly. The HAM-D correlated most strongly with Structured Clinical Interview for DSM-IV Dissociative Disorders diagnoses. Improvement in depression was similar on all outcome measures in both treatment and control groups. ConclusionsThe psychometric properties of the revised depression instruments are more than adequate for routine use in adults with SCI and are responsive to clinical improvement. The PHQ-9 is the simplest instrument with measurement properties as good as or better than those of the other instruments and required the fewest modifications.

Interviewing and Urine Drug Toxicology Screening in a Pediatric Pain Management Center: An Analysis of Analgesic Nonadherence and Aberrant Behaviors in Adolescents and Young Adults.

Many adolescents and young adults report having chronic pain. Urine drug toxicology (UDT) is not routinely used in the pediatric pain management population, despite more routine use in adults with pain, particularly those prescribed opioids. As a first step toward establishing monitoring practices in pediatric and adolescent pain management, the present study evaluated the role of UDT in conjunction with a standard clinical interview in identifying the rate of adherence to an established analgesic regimen. The study also aimed to assess the use of UDT in identifying possible aberrant behaviors in this population. Data were acquired from a convenience sample of 50 pediatric and adolescent pain management initial consultations, during which a clinical interview and UDT were conducted. Data were analyzed to determine adherence to an established analgesic prescription regimen, and for identification of aberrant behaviors including concurrent use of illicit substances and prescription medication misuse. Other pertinent demographic and clinical factors were examined as factors in adherence. Opioid medications were prescribed for 42% of the sample receiving pain medications, and 22% of the sample was nonadherent to their prescription analgesic regimen. Factors associated with a higher likelihood of nonadherence were an older age and having an opioid prescription. The majority (90%) of those nonadherent to their analgesic regimen displayed some form of aberrant behavior. Among the nonadherent patients, 50% were identified by UDT alone, and 50% were identified by self-report during the clinical encounter. These results highlight the challenges of identifying nonadherence to a prescription regimen among adolescents with chronic pain. In addition, this preliminary work suggests that UDT could be used in conjunction with careful clinical interviewing to substantiate patient report and increase the likelihood of detecting analgesic nonadherence and aberrant behaviors.

Decompressive craniectomy: indications and techniques

Introduction: Decompressive craniectomy (DC) is a surgical method indicated for immediate reduction of intracranial pressure (ICP) in general facing brain swelling, acute subdural hematoma, and some non-traumatic diseases. The technique consists of craniectomy and expansion of the dura-mater to accommodate the swollen brain. Literature review: several studies with DC indications show distinct results. There is no evidence to justify its routine use in adults with serious traumatic brain injury (TBI); however, it is indicated in children. Discussion: the refractoriness of intracranial hypertension (ICH) towards clinical measures is an indirect finding of cerebral auto-regulation loss, which configures the presence of Brain Swelling (BS), or swelling of the brain. DC is indicated in cases of BS, being bi- (Marshall III) or unilateral (Marshall IV). The technique requires broad bone removal, greater than the usually used in bruises and contusions. The incision in ‘T’- Kemp is preferred for allowing broad access to the frontotemporoparietal regions and great bone decompression. After craniectomy, dural diaeresis followed by duroplastia is conducted and, finally with the replacement of the bone flap to its original location after bulging reduction. Conclusion: DC is effective in immediately reducing ICP, avoiding ICH, which is a factor for poor prognosis. Its usefulness is especially observed if carried out prematurely in TBI victims with ICH when compared to being carried out

Issues Related to the Decennial Tetanus-Diphtheria Toxoid Booster Recommendations in Adults

In terms of disease prevention, reduction of adverse reactions, and cost benefit studies, a strong case can be made for a policy that focuses on assuring high levels of primary immunization with tetanus and diphtheria (Td) toxoids and abandons the decennial Td booster in favor of a single midlife booster at age 50-65 years. The addition of acellular pertussis antigens to Td for routine use in adults has potential problems in terms of schedule, cost, and possible adverse reactions. Careful risk/benefit studies are necessary to evaluate its effectiveness and priority.

Cellular and acellular pertussis vaccines in adults.

Immunization against pertussis after childhood previously was considered unnecessary, because severe illness and complications rarely developed in older persons. The rising incidence of pertussis among older adolescents and adults and the transmission of infection from adults to infants suggest that booster immunization may be necessary to more effectively control pertussis in all age groups. Whole cell pertussis vaccines are regarded as unsuitable for routine use in adults because of reports of frequent moderate to severe reactogenicity at the injection site and occasional systemic reactions. The introduction of safe and effective acellular pertussis vaccines provides us with an opportunity to reconsider booster immunization of adolescents and adults. Several vaccines containing purified component(s) of Bordetella pertussis have been well tolerated and highly immunogenic when given to healthy adults. A clear understanding of the impact of pertussis in adolescents and adults will help to define the need for booster immunization after childhood.

Advantages of venous bypass during orthotopic transplantation of the liver.

Venous bypass restores normal hemodynamic physiology during the critical anhepatic phase of orthotopic transplantation of the liver. Its routine use in adults undergoing transplantation in Pittsburgh has resulted in lower operative blood losses, a lower frequency of postoperative renal failure, and a greater probability of survival for all but the highest risk patients. Because it allows for a longer anhepatic phase, the surgeon has the option of tailoring the native hepatectomy to the needs of the individual case, even to the point, in difficult cases, of obtaining most of the hemostasis after removal of the native liver, but before sewing in the donor organ. Selective use of bypass in children may offer similar advantages.

Evaluation of the three hour metyrapone test in adults.

The prolonged metyrapone test is used to assess the hypothalamic-pituitary-adrenal axis. The dynamic responses of cortisol, ACTH and 11-deoxycortisol over the 3 h of the single morning dose metyrapone test have been examined in fourteen normal adult subjects. In every case there was a rapid, sustained fall in cortisol, but the resultant ACTH responses were extremely variable and in two subjects did not exceed values obtained during the control studies. The rise in 11-deoxycortisol was also variable and in several instances occurred without any significant elevation in ACTH. In these cases, the rise in 11-deoxycortisol may be due to a normal level of production of steroids with a shift from cortisol to 1-deoxycortisol induced by the metyrapone. Thus, the hypothalamic-pituitary-adrenal axis may not be adequately tested, and this together with the high incidence of unpleasant side effects, makes the 3 h oral metyrapone test unsatisfactory for routine use in adults.
