ABSTRACT

BACKGROUND: Veterans of the first Gulf War (1990-1991) are reaching middle and older adulthood in differing degrees of health and biological age. Many Gulf War veterans report myriad negative symptoms classified as Gulf War illness (GWI), a chronic multi-symptom illness. OBJECTIVES: To describe and analyze deficit accumulation, among veterans with Severe GWI (SGWI+) and those without Severe GWI (SGWI-), to assess the association between a medically unexplained illness and aging. DESIGN: This study uses a retrospective cohort design with quasi-longitudinal data. SETTING: The recruitment sample included 10,042 Gulf War era veterans across all four US Census regions. PARTICIPANTS: The analytic sample included 1,054 participants of the GWECB for whom SGWI case status could be determined and who had valid responses for at least 90% of the deficits included in the deficit accumulation index. MEASUREMENTS: Chronic health conditions were retroactively reported, including year of diagnosis, enabling us to create a longitudinal measure of deficit accumulation. This deficit accumulation index (DAI) ranged from 0-1 for each respondent in each year between 1991-2013. We compare veterans with SGWI+ to those with SGWI- using the CDC case definition. RESULTS: Most veterans in our sample could expect to spend more years with moderate or substantial deficits than without deficits. SGWI+ was associated with spending more years with substantial deficits than those with SGWI-. Veterans in middle age (age 35-65) experienced more years with substantial deficits than younger veterans. Individuals with SGWI+ had 13 times the hazard of accumulating substantial deficits than those without. CONCLUSIONS: This study demonstrated that veterans with SGWI+, even those in midlife, experienced aging as measured by accumulating deficits. Practitioners should consider patients with multi-symptom illnesses as at risk of accelerated aging, tailoring treatments to address patients' holistic needs.

ABSTRACT

BACKGROUND: Gulf War Illness (GWI) is a chronic, multi-symptom disorder affecting 25%-32% of Gulf War veterans. Veterans with GWI disproportionately suffer from gastrointestinal (GI) disorders. Given the increasing evidence supporting a gut-brain axis, we explore the relationship between post-traumatic stress disorder (PTSD), GWI, and self-reported GI disorders among GW veterans. METHODS: Veterans from the Gulf War Era Cohort and Biorepository responded to a mail-based survey (N = 1058). They were stratified by GWI (Centers for Disease Control definition) and PTSD status. This yielded three groups: GWI-, GWI+/PTSD-, and GWI+/PTSD+. Multivariable logistic regression adjusting for demographic and military characteristics examined associations between GWI/PTSD groups and GI disorders. Results were expressed as adjusted odds ratios (aOR) with 95% confidence intervals (95% CI). KEY RESULTS: The most frequently reported GI disorders were irritable bowel syndrome (IBS), gastroesophageal reflux disease (GERD), and colon polyps (CP). The GWI+/PTSD+ group had a higher odds of these disorders than the GWI+/PTSD- group (aORIBS  = 3.12, 95% CI: 1.93-5.05; aORGERD  = 2.04, 95% CI: 1.44-2.90; aORCP  = 1.85, 95% CI: 1.23-2.80), which had a higher odds of these disorders than the GWI- group (aORIBS  = 4.38, 95% CI: 1.55-12.36; aORGERD  = 2.51 95% CI: 1.63-3.87; aORCP  = 2.57, 95% CI: 1.53-4.32). CONCLUSIONS & INFERENCES: GW veterans with GWI and PTSD have significantly higher odds of specific self-reported GI disorders than the other groups. Given the known bidirectional influences of the gut and brain, these veterans may benefit from a holistic healthcare approach that considers biopsychosocial contributors to the assessment and management of disease.

ABSTRACT

BACKGROUND: Parental criminal justice system (CJS) involvement is a marker for child protective services (CPS) involvement. OBJECTIVE: To document how parental criminal case processing affects children's CPS involvement. PARTICIPANTS AND SETTING: Participants included mothers and fathers with a serious criminal charge (mothers = 78,882; fathers = 165,070) and without any criminal charge (mothers = 962,963; fathers = 743,604) between 2008-2012. Statewide North Carolina records on court proceedings, births, CPS assessments/investigations, and foster care placements were used. METHODS: The observational unit was an individual's first charge date of a year. Outcomes were CPS assessment/investigation and foster care entry within six months and alternatively three years following the charge. Key explanatory variables were whether the charges resulted in prosecution, conviction following prosecution, and an active sentence conditional on conviction. An instrumental variables approach was used. RESULTS: Parents charged with a criminal offense had higher rates of having a CPS assessment/investigation during the three years preceding the charge than parents who were not charged. Among mothers who were convicted, CPS assessment/investigation increased 8.1 percent (95 % CI: 2.2, 13.9) and 9.5 percent (95 % CI: 1.3, 17.6) 6 months and 3 years following the charge. An active sentence increased CPS assessment/investigations by 21.6 percent (95 % CI: 6.4, 36.7) within 6 months. For fathers, active sentence increased foster care placement by 1.6 percent (95 % CI: 0.24, 2.9) within 6 months of the criminal charge. CONCLUSIONS: Changing parental incarceration rates would change CPS caseloads substantially. The criminal justice and CPS systems work with overlapping populations, data and services sharing should be considered a high priority.

ABSTRACT

BACKGROUND: With its increasing incidence, nonalcoholic fatty liver disease (NAFLD) is of particular concern in the Veterans Health Administration (VHA). AIMS: To evaluate risk factors for advanced fibrosis in biopsy-proven NAFLD in the VHA, to identify patients at risk for adverse outcomes. METHODS: In randomly selected cases from VHA databases (2005-2015), we performed a retrospective case-control study in adults with biopsy-defined NAFLD or normal liver. RESULTS: Of 2091 patients reviewed, 399 met inclusion criteria. Normal controls (n = 65) had normal liver function. The four NAFLD cohorts included: NAFL steatosis (n = 76), nonalcoholic steatohepatitis (NASH) without fibrosis (n = 68), NAFLD/NASH stage 1-3 fibrosis (n = 82), and NAFLD/NASH cirrhosis (n = 70). NAFLD with hepatocellular carcinoma (HCC) was separately identified (n = 38). Most patients were older White men. NAFLD patients with any fibrosis were on average severely obese (BMI>35 kg/m2 ). Diabetes (54.4%-79.6%) and hypertension (85.8%-100%) were more common in NAFLD with fibrosis or HCC. Across NAFLD, 12.3%-19.5% were enrolled in diet/exercise programs and 0%-2.6% had bariatric surgery. Hispanics exhibited higher rates of NASH (20.6%), while Blacks had low NAFLD rates (1.4%-11.8%), particularly NAFLD cirrhosis and HCC (1.4%-2.6%). Diabetes (OR 11.8, P < .001) and BMI (OR 1.4, P < .001) were the most significant predictors of advanced fibrosis. CONCLUSIONS: In the VHA, diabetes and severe obesity increased risk for advanced fibrosis in NAFLD. Of these patients, only a small proportion (~20%) had enrolled in diet/exercise programs or had bariatric surgery (~2%). These results suggest that providers should focus/tailor interventions to improve outcomes, particularly in those with diabetes and severe obesity.

ABSTRACT

Mutations in the human ALMS1 gene cause Alström syndrome (AS), a progressive disease characterized by neurosensory deficits and by metabolic defects including childhood obesity, hyperinsulinemia and Type 2 diabetes. Other features that are more variable in expressivity include dilated cardiomyopathy, hypertriglyceridemia, hypercholesterolemia, scoliosis, developmental delay and pulmonary and urological dysfunctions. ALMS1 encodes a ubiquitously expressed protein of unknown function. To obtain an animal model in which the etiology of the observed pathologies could be further studied, we generated a mouse model using an Alms1 gene-trapped ES cell line. Alms1-/- mice develop features similar to patients with AS, including obesity, hypogonadism, hyperinsulinemia, retinal dysfunction and late-onset hearing loss. Insulin resistance and increased body weight are apparent between 8 and 12 weeks of age, with hyperglycemia manifesting at approximately 16 weeks of age. In addition, Alms1-/- mice have normal hearing until 8 months of age, after which they display abnormal auditory brainstem responses. Diminished cone ERG b-wave response is observed early, followed by the degeneration of photoreceptor cells. Electron microscopy revealed accumulation of intracellular vesicles in the inner segments of photoreceptors, whereas immunohistochemical analysis showed mislocalization of rhodopsin to the outer nuclear layer. These findings suggest that ALMS1 has a role in intracellular trafficking.

ABSTRACT

INTRODUCTION: Spectrin, a heterodimer of alpha- and beta-subunits, is the major protein component of the red blood cell membrane skeleton. The mouse mutation, sph, causes an alpha-spectrin-deficient hereditary spherocytosis with the severe phenotype typical of recessive hereditary spherocytosis in humans. The sph mutation maps to the erythroid alpha-spectrin locus, Spna1, on Chromosome 1. MATERIALS AND METHODS: Scanning electron microscopy, osmotic gradient ektacytometry, cDNA cloning, RT-PCR, nucleic acid sequencing, and Northern blot analyses were used to characterize the wild type and sph alleles of the Spna1 locus. RESULTS: Our results confirm the spherocytic nature of sph/sph red blood cells and document a mild spherocytic transition in the +/sph heterozygotes. Sequencing of the full length coding region of the Spna1 wild type allele from the C57BL/6J strain of mice reveals a 2414 residue deduced amino acid sequence that shows the typical 106-amino-acid repeat structure previously described for other members of the spectrin protein family. Sequence analysis of RT-PCR clones from sph/sph alpha-spectrin mRNA identified a single base deletion in repeat 5 that would cause a frame shift and premature termination of the protein. This deletion was confirmed in sph/sph genomic DNA. Northern blot analyses of the distribution of Spna1 mRNA in non-erythroid tissues detects the expression of 8, 2.5 and 2.0 kb transcripts in adult heart. CONCLUSION: These results predict the heart as an additional site where alpha-spectrin mutations may produce a phenotype and raise the possibility that a novel functional class of small alpha-spectrin isoforms may exist.

ABSTRACT

Mouse erythroid ankyrin is encoded by the Ank1 gene on Chromosome 8. The best studied isoform is 210 kDa and contains three large functional domains. We have recently reported a small Ank1 isoform (relative mobility 25 kDa) that localizes to the M and Z lines in skeletal muscle. Analyses of cDNA and genomic clones show that three transcripts of 3.5, 2.0, and 1.6 kb code for this protein. The different transcript sizes are due to their 3'-untranslated regions. They are encoded by a new first exon located in intron 39 of the Ank1 gene and three previously described Ank1 exons (40, 41, and 42). The 5'-flanking region contains a putative muscle-specific promoter. The sequence of the first 72 amino acids is novel and is predicted to form a transmembrane helix at the NH2-terminus. Functional testing of the putative transmembrane segment indicates that it acts as a membrane anchor, suggesting that the new Ank1 isoform may play an important role in organizing the contractile apparatus within the cell.
