Evidence for the Effectiveness and Acceptability of e-SBI or e-SBIRT in the Management of Alcohol and Illicit Substance Use in Pregnant and Post-partum Women.

Alcohol and illicit psychoactive drug use during pregnancy have increased worldwide, putting women and their children's health and development at risk. Multiple drug use, comorbid psychiatric disorders, sexual and physical abuse are common in women who use alcohol and drugs during pregnancy. The effects on the mother include poor reproductive and life-long health, legal, family, and social problems. Additionally, the exposed child is at increased risk of long-term physical health, mental health, and developmental problems. The stigma associated with substance use during pregnancy and some clinicians' reticence to inquire about substance use means many women are not receiving adequate prenatal, substance abuse, and mental health care. Evidence for mHealth apps to provide health care for pregnant and post-partum women reveal the usability and effectiveness of these apps to reduce gestational weight gain, improve nutrition, promote smoking cessation and manage gestational diabetes mellitus, and treat depression and anxiety. Emerging evidence suggests mHealth technology using a public health approach of electronic screening, brief intervention, or referral to treatment (e-SBIRT) for substance use or abuse can overcome the typical barriers preventing women from receiving treatment for alcohol and drug use during pregnancy. This brief intervention delivered through a mobile device may be equally effective as SBIRT delivered by a health care professional in preventing maternal drug use, minimizing the effects to the exposed child, and providing a pathway to therapeutic options for a substance use disorder. However, larger studies in more diverse settings with women who have co-morbid mental illness and a constellation of social risk factors that are frequently associated with substance use disorders are needed.

Results of the ADHERE upper airway stimulation registry and predictors of therapy efficacy.

OBJECTIVE/HYPOTHESIS: The ADHERE Registry is a multicenter prospective observational study following outcomes of upper airway stimulation (UAS) therapy in patients who have failed continuous positive airway pressure therapy for obstructive sleep apnea (OSA). The aim of this registry and purpose of this article were to examine the outcomes of patients receiving UAS for treatment of OSA. STUDY DESIGN: Cohort Study. METHODS: Demographic and sleep study data collection occurred at baseline, implantation visit, post-titration (6 months), and final visit (12 months). Patient and physician reported outcomes were also collected. Post hoc univariate and multivariate analysis was used to identify predictors of therapy response, defined as ≥50% decrease in Apnea-Hypopnea Index (AHI) and AHI ≤20 at the 12-month visit. RESULTS: The registry has enrolled 1,017 patients from October 2016 through February 2019. Thus far, 640 patients have completed their 6-month follow-up and 382 have completed the 12-month follow-up. After 12 months, median AHI was reduced from 32.8 (interquartile range [IQR], 23.6-45.0) to 9.5 (IQR, 4.0-18.5); mean, 35.8 ± 15.4 to 14.2 ± 15.0, P < .0001. Epworth Sleepiness Scale was similarly improved from 11.0 (IQR, 7-16) to 7.0 (IQR, 4-11); mean, 11.4 ± 5.6 to 7.2 ± 4.8, P < .0001. Therapy usage was 5.6 ± 2.1 hours per night after 12 months. In a multivariate model, only female sex and lower baseline body mass index remained as significant predictors of therapy response. CONCLUSIONS: Across a multi-institutional study, UAS therapy continues to show significant improvement in subjective and objective OSA outcomes. This analysis shows that the therapy effect is durable and adherence is high. LEVEL OF EVIDENCE: 2 Laryngoscope, 130:1333-1338, 2020.

L-Deprenyl reverses age-associated decline in splenic norepinephrine, interleukin-2 and interferon-γ production in old female F344 rats.

UNLABELLED: Aging in female rats is associated with cessation of reproductive cycles, development of mammary cancer, and increased incidence of autoimmune diseases. Previously, we demonstrated an age-related decline in sympathetic noradrenergic (NA) innervation in the spleen and lymph nodes of female F344 rats accompanied by significantly reduced natural killer cell activity, interleukin (IL)-2 and interferon (IFN)-γ production, and T- and B-cell proliferation, suggesting possible links between sympathetic activity and immunosenescence. OBJECTIVES: The aim of this study is to investigate the effects of L-(-)-deprenyl, a monoamine oxidase-B inhibitor, on the sympathetic nervous system and cell-mediated immune responses in old female rats. METHODS: Low doses of L-deprenyl (0.25 or 1.0 mg/kg body weight, BW) were administered intraperitoneally to 19- to 21-month-old female F344 rats for 8 weeks. To assess the stereoselectivity of the effects of deprenyl on splenic sympathetic activity and immune responses, the D-enantiomer (D-(+)-deprenyl; 1.0 mg/kg BW) was also included in the studies. Norepinephrine (NE) concentration and content, and mitogen-induced T-cell proliferation and cytokine production were assessed in the splenocytes after deprenyl treatment. RESULTS: Treatment with L-deprenyl reversed the age-related decrease in NE concentration and content and IFN-γ production, and increased IL-2 production in the spleen while D-deprenyl did not affect the age-associated reduction in splenic NE levels or cytokine production. CONCLUSIONS: These findings demonstrate that L-deprenyl exerts neurorestorative and immunostimulatory effects on the sympathetic nervous system and cell-mediated immune responses during aging and provides evidence for a causal relationship between some aspects of immunosenescence and the age-related decline in sympathetic nerves in the spleens of female F344 rats.

Hearing results and quality of life after streptomycin/dexamethasone perfusion for Meniere's disease.

OBJECTIVES/HYPOTHESIS: To evaluate the hearing changes and quality-of-life outcomes of 393 cases of streptomycin/dexamethasone inner ear perfusion performed by the primary author on 312 ears of 299 patients with Meniere's disease between July 2002 and May 2010. STUDY DESIGN: Retrospective chart review. METHODS: Objective arm: A database was used to compile pretreatment and post-treatment audiograms as well as basic demographic information, dates of treatment, number of treatments, and which ear was treated. All patients met the 1995 American Academy of Otolaryngology-Head and Neck Surgery Committee on Hearing and Equilibrium Guidelines for the diagnosis and evaluation of therapy in Meniere's disease. All patients underwent one or more 3-day treatments consisting of daily intratympanic injections of a low-dose streptomycin/high-dose dexamethasone mixture plus intravenous dexamethasone. The end point for treatment was adequate control of vertigo. Subjective arm: The Meniere's Disease Outcomes Questionnaire survey was used to assess patients' quality of life after receiving streptomycin/dexamethasone inner ear perfusion. All procedures were performed by the primary author at the Shea Ear Clinic, a tertiary-referral otology clinic and outpatient surgery center. RESULTS: After a single 3-day treatment, the average change in pure tone average was 0.89 dB (±11). The average change in word recognition score was 0.49% (±17). The average number of days from treatment to follow-up audiogram was 94 with a range of 8 to 1,603. Clinically significant hearing loss occurred after 62 of 393 (15.7%) treatments. Severe hearing loss occurred after 20 of 393 treatments (5.0%). The percentage of ears with clinically significant hearing loss after all treatments was 56 of 312 (17.9%). A total of 215 surveys were returned from 383 patients (56.1%) to whom they were mailed. There were 90% of patients who indicated improvement in quality of life after treatment and 88% who indicated improvement in their "vertigo subscore," a domain within the survey that focuses on vertigo control. CONCLUSIONS: Streptomycin/dexamethasone inner ear perfusion is as safe to the hearing of patients with Meniere's disease as other aminoglycoside regimens and provides a significant improvement in quality of life.

Blood leucocyte telomere DNA content predicts vascular telomere DNA content in humans with and without vascular disease.

AIMS: Previous studies have suggested that reduced telomere length in circulating leucocytes in humans is associated with premature vascular disease and by implication, accelerated vascular ageing. Importantly, a link between telomere length in circulating leucocytes and the blood vessel wall has never been established. We, thus, investigated the relationship between vascular wall and circulating leucocyte telomere length in humans with and without overt vascular disease. METHODS AND RESULTS: Aortic biopsies and paired blood leucocytes were obtained from 20 patients with asymptomatic abdominal aortic aneurysms (AAAs), undergoing elective open repair, and 12 morphologically normal aortas from a group of cadaveric organ donors of similar mean age. Telomere content was compared by quantitative PCR and expressed as telomere:genomic DNA ratio. The telomere:genomic DNA content was significantly reduced in wall biopsies of AAA vs. normal aorta, and this difference remained after adjusting for age and gender. There were strong correlations between leucocyte and vascular telomere content when the AAA and control groups were analysed either separately or grouped irrespective of the presence of vascular disease (r = 0.62, P < 0.001). CONCLUSION: The findings demonstrate that leucocyte DNA content is predictive of vascular telomere content and is an accurate surrogate for human vascular age.

Randomized, controlled trial of intramuscular or intracoronary injection of autologous bone marrow cells into scarred myocardium during CABG versus CABG alone.

BACKGROUND: Studies of the transplantation of autologous bone marrow cells (BMCs) in patients with chronic ischemic heart disease have assessed effects on viable, peri-infarct tissue. We conducted a single-blinded, randomized, controlled study to investigate whether intramuscular or intracoronary administration of BMCs into nonviable scarred myocardium during CABG improves contractile function of scar segments compared with CABG alone. METHODS: Elective CABG patients (n = 63), with established myocardial scars diagnosed as akinetic or dyskinetic segments by dobutamine stress echocardiography and confirmed at surgery, were randomly assigned CABG alone (control) or CABG with intramuscular or intracoronary administration of BMCs. The BMCs, which were obtained at the time of surgery, were injected into the mid-depth of the scar in the intramuscular group or via the graft conduit supplying the scar in the intracoronary group. Contractile function was assessed in scar segments by dobutamine stress echocardiography before and 6 months after treatment. RESULTS: The proportion of patients showing improved wall motion in at least one scar segment after BMC treatment was not different to that observed in the control group (P = 0.092). Quantitatively, systolic fractional thickening in scar segments did not improve with BMC administration. Furthermore, BMCs did not improve scar transmurality, infarct volume, left ventricular volume, or ejection fraction. CONCLUSION: Injection of autologous BMCs directly into the scar or into the artery supplying the scar is safe but does not improve contractility of nonviable scarred myocardium, reduce scar size, or improve left ventricular function more than CABG alone.

Genome-wide association analysis identifies 20 loci that influence adult height.

Adult height is a model polygenic trait, but there has been limited success in identifying the genes underlying its normal variation. To identify genetic variants influencing adult human height, we used genome-wide association data from 13,665 individuals and genotyped 39 variants in an additional 16,482 samples. We identified 20 variants associated with adult height (P < 5 x 10(-7), with 10 reaching P < 1 x 10(-10)). Combined, the 20 SNPs explain approximately 3% of height variation, with a approximately 5 cm difference between the 6.2% of people with 17 or fewer 'tall' alleles compared to the 5.5% with 27 or more 'tall' alleles. The loci we identified implicate genes in Hedgehog signaling (IHH, HHIP, PTCH1), extracellular matrix (EFEMP1, ADAMTSL3, ACAN) and cancer (CDK6, HMGA2, DLEU7) pathways, and provide new insights into human growth and developmental processes. Finally, our results provide insights into the genetic architecture of a classic quantitative trait.

Evidence for genetic regulation of endothelial progenitor cells and their role as biological markers of atherosclerotic susceptibility.

AIMS: Endothelial progenitor cells (EPCs) are found in the peripheral circulation and are capable of endothelial repair and neovascularization. EPC number and function are reduced in subjects with cardiovascular risk factors or proven coronary artery disease (CAD). We hypothesized that EPC number and/or function may be genetically regulated and may vary in healthy adult offspring depending on parental history of CAD. METHODS AND RESULTS: We studied 102 subjects comprising 24 healthy parent-healthy offspring pairs and 27 CAD parent-healthy offspring pairs. We measured the number of circulating CD34(+)VEGFR-2(+) and AC133(+)VEGFR-2(+) EPCs, the number of EPCs grown in culture, and the migration capacity of cultured EPCs towards vascular endothelial growth factor. There was significant correlation in the number of cultured EPCs between healthy parents and their offspring (R = 0.492, P = 0.015) and CAD parents and their offspring (R = 0.751, P < 0.001). Offspring of subjects with CAD had significantly higher numbers of circulating CD34(+)VEGFR-2(+) and AC133(+)VEGFR-2(+) cells (P = 0.018 and P < 0.001, respectively). There was no difference in migration capacity between groups. CONCLUSION: Our results suggest that EPC number is, at least in part, genetically regulated. Circulating EPCs may represent biological markers of occult vascular damage in offspring with hereditary risk of CAD.

Outcome after pulmonary radiotherapy in Wilms' tumor patients with pulmonary metastases at diagnosis: a UK Children's Cancer Study Group, Wilms' Tumour Working Group Study.

PURPOSE: To evaluate the effect of whole lung radiotherapy on event-free and overall survival of children with Stage IV Wilms' tumor with pulmonary metastases at diagnosis and to ascertain factors that may have led to the decision to withhold radiotherapy. METHODS AND MATERIALS: We compared recurrence and mortality risks of patients with pulmonary metastases at diagnosis enrolled in the UKW2 and UKW3 clinical trials (1986-2001) according to treatment with pulmonary radiotherapy. RESULTS: Of 102 eligible patients (43 patients in UKW2 and 59 patients in UKW3), 72 (71%) received pulmonary radiotherapy; 30 (29%) did not. After a median follow-up of 9.3 years (range, 0.6-14.1 years), event-free survival was 79.2% (95% confidence interval [CI], 67.8-86.9%) in patients who received pulmonary radiotherapy compared with 53.3% (95% CI, 34.3-69.1%) in patients who did not receive it (p = 0.006), with a hazard ratio of 2.66 (95% CI, 1.28-5.52; p = 0.009). There was no difference in overall survival (84.7% [95% CI, 74.1-91.2%] vs. 73.2% [95% CI, 53.4-85.6%], respectively; p = 0.157). Pulmonary radiotherapy reduced the chance of lung relapse (8.3% vs. 23.3%; p = 0.039). The omission of radiotherapy did not seem to be consistently associated with any specific clinical or radiologic features. CONCLUSIONS: Outcome may be compromised if pulmonary radiotherapy is omitted in children with Wilms' tumor with pulmonary metastases. There was a significant effect on event-free survival; the risk of an event, particularly lung recurrence, was increased nearly threefold. Strategies for selection of children for avoidance of pulmonary irradiation need to be developed in a controlled fashion.

Immediate nephrectomy versus preoperative chemotherapy in the management of non-metastatic Wilms' tumour: results of a randomised trial (UKW3) by the UK Children's Cancer Study Group.

PURPOSE: To determine if patients receiving preoperative chemotherapy with vincristine and actinomycin D for non-metastatic Wilms' tumour have a more advantageous stage distribution and so need less treatment compared to patients who have immediate nephrectomy, without adversely affecting outcome. METHODS: Between 1991 and 2001, a total of 205 patients with newly diagnosed non-metastatic renal tumours, of which 186 had Wilms' histologies, were randomly assigned either to immediate surgery or to 6 weeks preoperative chemotherapy and then delayed surgery. Both groups of children received postoperative chemotherapy according to tumour stage and histology determined at the time of nephrectomy. RESULTS: There was a significant improvement in the stage distribution for patients with Wilms' histologies receiving delayed surgery compared to those having immediate nephrectomy (stage I: 65.2% versus 54.3%; stage II: 23.9% versus 14.9%; stage III: 9.8% versus 29.8%, chi2 test for trend=7.02, p=0.008). This improvement resulted in 20% fewer children receiving radiotherapy or doxorubicin yet event-free and overall survivals at 5 years of 79.6% and 89.0%, respectively, were similar in the two groups. CONCLUSION: Six weeks of preoperative chemotherapy with vincristine and actinomycin D results in a significant shift towards a more advantageous stage distribution and hence reduction in therapy, while maintaining excellent event free and overall survival in children with non-metastatic Wilms' tumour. Around 20% of survivors were therefore spared the late-effects of doxorubicin or radiotherapy. Our results suggest that all children with non-metastatic Wilms' tumour should receive chemotherapy prior to tumour resection.

Wilms' tumor with intracaval thrombus in the UK Children's Cancer Study Group UKW3 trial.

BACKGROUND/PURPOSE: To define the clinical characteristics and surgical management of intracaval involvement in patients enrolled in the UKW3 trial (1991-2001), which recommended elective preoperative chemotherapy for such cases. METHODS: Cases were identified from preoperative imaging and surgical trial forms. These asked specific questions about whether the surgeon suspected intracaval extension at diagnosis or found it at nephrectomy. For tumors with Wilms' histology, original case notes were examined. RESULTS: Of 842 patients registered in UKW3, 730 (87%) had Wilms' tumor. Among them, 59 (8.1%) had evidence of intracaval extension, either documented at diagnosis (53) or found unexpectedly at nephrectomy (6). Intracaval extension was also seen in tumors of other histology. The level of thrombus was intraatrial (10), suprahepatic (9), retrohepatic (8), infrahepatic (26), and unknown (6). The median age at diagnosis was 3.75 years compared to 2.97 years in patients without inferior vena cava thrombus (P < .0001). Fifty-two of 59 received preoperative chemotherapy. Thirty-one (52%) needed cavotomy, and 3 (30%) with intraatrial extension required cardiopulmonary bypass. The commonest operative complication was significant hemorrhage and resulted in mortality in 3 cases. CONCLUSIONS: Preoperative chemotherapy is a useful adjunct to shrink the tumor and thrombus. This reduces the requirement for cavotomy and cardiopulmonary bypass. Intraoperative hemorrhage remains a significant cause of operative morbidity and mortality.

Aging and sympathetic modulation of immune function in Fischer 344 rats: effects of chemical sympathectomy on primary antibody response.

In aged Fischer 344 (F334) rats, sympathetic innervation of the spleen is markedly diminished compared with young rats. To determine if this diminished noradrenergic (NA) innervation maintains a functional connection with the immune system, 3- and 17-month-old male F344 rats were treated with the NA-selective neurotoxin, 6-hydroxydopamine (6-OHDA), to ablate peripheral NA nerve fibers. In sympathectomized rats immunized with keyhole limpet hemocyanin (KLH), a T-dependent protein antigen, anti-KLH IgM, IgG, IgG1, IgG2b antibody titers were increased in young and old rats 14 days after immunization compared to vehicle controls. Furthermore, the number of IgM and IgG anti-KLH antibody-secreting spleen cells was elevated 7 and 14 days post-immunization. These effects were prevented by pretreatment with desipramine, a catecholamine uptake blocker that blocks 6-OHDA uptake and subsequent sympathectomy. Chemical sympathectomy also increased KLH-induced proliferation in vitro by spleen cells from old, but not young animals. Isoproterenol (ISO), a beta-adrenergic receptor agonist, elicited a rise in cAMP in spleen cells from NA-intact young and old rats, but the increase was attenuated in spleen cells from old rats. These results demonstrate that, although NA innervation in the F344 rat spleen is diminished with age, sympathetic signaling of the immune system remains intact. Thus, the SNS can inhibit antibody produced in response to a protein antigen in both young and old F344 rats.

Chemical sympathectomy has no effect on the severity of murine AIDS: murine AIDS alone depletes norepinephrine levels in infected spleen.

Numerous studies have shown that alterations in sympathetic nervous system (SNS) function produced by beta-adrenergic receptor blockade or chemical sympathectomy can produce changes in T and B lymphocyte function and both innate and acquired immune responses. However, fewer studies have investigated changes in immune response following SNS alterations in animal models of disease. We tested whether blocking SNS activity using 6-OHDA or the beta-receptor antagonist nadolol alters the typical pattern in production of T helper 1 (Th1) and Th2 cytokines seen in cultures of spleen cells from C57BL/6 mice infected with murine AIDS (MAIDS). We found that neither method of sympathetic blockade affected cytokine response to MAIDS. We also found that the norepinephrine concentration and content of the spleen were reduced dramatically by the MAIDS infection itself at 3 and 6 weeks after LP-BM5 inoculation. This finding has not been previously reported in mice with MAIDS and suggests that the viral infection itself produces a functional sympathectomy in the spleen, a target of that infection.

Loss of cardiac sympathetic neurotransmitters in heart failure and NE infusion is associated with reduced NGF.

Sympathetic neurotransmitters are diminished in cardiac efferent nerve endings in congestive heart failure (CHF). Similar changes occur after exogenous norepinephrine (NE) infusion. Since NE reduces nerve growth factor (NGF) in cultured cardiomyocytes, we proposed to determine whether the loss of noradrenergic transmitters in the failing heart is caused by the NE-mediated reduction of NGF or its neurotrophic receptor tyrosine kinase A (TrKA). Dogs were assigned to receive either rapid ventricular pacing (225 beats/min) or NE infusion (0.5 microg/kg/min) for 8 wk. Control animals received either cardiac pacing of 100 beats/min or saline infusion. We measured NGF and TrKA proteins by Western blot and immunocytochemistry and measured NGF and TrKA mRNAs by reverse transcription polymerase chain reaction, neuronal catecholaminergic histofluorescence, tyrosine hydroxylase-immunostained profiles, and plasma NE. Rapid ventricular pacing produced CHF with increased plasma NE, decreased myocardial NGF protein (0.61 +/- 0.07 vs. 1.04 +/- 0.04, P < 0.05), TrKA protein (0.75 +/- 0.08 vs. 0.98 +/- 0.06, P < 0.05), NGF and TrKA mRNAs and reduced catecholaminergic histofluorescence (197 +/- 23 vs. 485 +/- 43, P < 0.05), and tyrosine hydroxylase profiles (360 +/- 51 vs. 773 +/- 36, P < 0.05). Decreases in tissue NGF and TrKA protein were also noted by immunocytochemistry. Similar changes occurred in NE-treated animals. Tissue NGF and TrKA levels correlated closely with the noradrenergic transmitter profiles. We conclude that cardiac NGF and TrKA are reduced by rapid ventricular pacing and NE infusion, and that these changes correlate with decreases of cardiac catecholaminergic and tyrosine hydroxylase profiles. Findings indicate that decrease of cardiac sympathetic transmitters in heart failure is associated with NE-mediated reduction of NGF and TrKA.
