Passive collection of ticks in New Hampshire reveals species-specific patterns of distribution and activity
Ticks and tick-borne diseases are increasing in the United States, including New Hampshire (NH). We report on the findings of an ongoing free crowdsourcing program spanning four years within NH. The date of tick’s submission was recorded along with species, sex, stage, location they were collected (translated into latitude and longitude), the activity the individual was doing when the tick was found, and host species. A total of 14,252 ticks belonging to subclass Acari, family Ixodidae and genera Ixodes, Dermacentor, Amblyomma, and Haemaphysalis was recorded from the period 2018–2021 throughout NH. A total of 2,787 Ixodes scapularis and 1,041 Dermacentor variabilis, were tested for the presence of Borrelia sp. (Spirochaetales: Spirochaetaceae), B. burgdorferi sensu lato, B. miyamotoi, B. mayonii, Babesia microti (Piroplasmida: Babesiidae), Anaplasma phagocytophilum (Rickettsiales: Anaplasmataceae), Francisella tularensis (Thiotrichales: Francisellaceae), and Rickettsia rickettsii (Rickettsiales: Rickettsiaceae) by PCR. For the I. scapularis ticks tested, the pathogen prevalence was 37% B. burgdorferi s.l. 1% B. miyamotoi, 6% A. phagocytophilum, and 5% Ba. microti. Only one D. variabilis resulted positive to F. tularensis. We created state-wide maps informing the differences of ticks as detailed by administrative divisions. Dermacentor variabilis peaked in June and I. scapularis peaked in May and October. The most reported activity by people with tick encounters was while walking/hiking, and the least was biking. Using the reported distribution of both species of ticks, we modeled their climate suitability in the target territory. In NH, I. scapularis and D. variabilis have distinct patterns of emergence, abundance, and distribution. Tick prevention is important especially during April–August when both tick species are abundant and active
Measuring the mixing scale of the ISM within nearby spiral galaxies
The spatial distribution of metals reflects, and can be used to constrain,
the processes of chemical enrichment and mixing. Using PHANGS-MUSE optical
integral field spectroscopy, we measure the gas phase oxygen abundances
(metallicities) across 7,138 HII regions in a sample of eight nearby disc
galaxies. In Paper I (Kreckel et al. 2019) we measure and report linear radial
gradients in the metallicities of each galaxy, and qualitatively searched for
azimuthal abundance variations. Here, we examine the two-dimensional variation
in abundances once the radial gradient is subtracted, Delta(O/H), in order to
quantify the homogeneity of the metal distribution and to measure the mixing
scale over which HII region metallicities are correlated. We observe low
(0.03--0.05 dex) scatter in Delta(O/H) globally in all galaxies, with
significantly lower (0.02--0.03 dex) scatter on small (<600 pc) spatial scales.
This is consistent with the measurement uncertainties, and implies the
two-dimensional metallicity distribution is highly correlated on scales of <600
pc. We compute the two point correlation function for metals in the disc in
order to quantify the scale lengths associated with the observed homogeneity.
This mixing scale is observed to correlate better with the local gas velocity
dispersion (of both cold and ionized gas) than with the star formation rate.
Selecting only HII regions with enhanced abundances relative to a linear radial
gradient, we do not observe increased homogeneity on small scales. This
suggests that the observed homogeneity is driven by the mixing introducing
material from large scales rather than by pollution from recent and on-going
star formation.Comment: 17 pages, 14 figures. Accepted for publication in MNRA

A Polymorphism in the HLA-DPB1 Gene Is Associated with Susceptibility to Multiple Sclerosis
We conducted an association study across the human leukocyte antigen (HLA) complex to identify loci associated with multiple sclerosis (MS). Comparing 1927 SNPs in 1618 MS cases and 3413 controls of European ancestry, we identified seven SNPs that were independently associated with MS conditional on the others (each ). All associations were significant in an independent replication cohort of 2212 cases and 2251 controls () and were highly significant in the combined dataset (). The associated SNPs included proxies for HLA-DRB1*15:01 and HLA-DRB1*03:01, and SNPs in moderate linkage disequilibrium (LD) with HLA-A*02:01, HLA-DRB1*04:01 and HLA-DRB1*13:03. We also found a strong association with rs9277535 in the class II gene HLA-DPB1 (discovery set , replication set , combined ). HLA-DPB1 is located centromeric of the more commonly typed class II genes HLA-DRB1, -DQA1 and -DQB1. It is separated from these genes by a recombination hotspot, and the association is not affected by conditioning on genotypes at DRB1, DQA1 and DQB1. Hence rs9277535 represents an independent MS-susceptibility locus of genome-wide significance. It is correlated with the HLA-DPB1*03:01 allele, which has been implicated previously in MS in smaller studies. Further genotyping in large datasets is required to confirm and resolve this association
Treatment response of bipolar and unipolar alcoholics to an inpatient dual diagnosis program.
Background: Depressed and bipolar alcoholics represent a significant affective subgroup that has a poorer prognosis than either diagnosis alone. To date few systematic treatment programs have been developed to treat dual diagnosis.
Methods: An inpatient treatment program was developed at St Patrick's Hospital Dublin to treat dual diagnosis clients with alcohol dependence and either unipolar or bipolar affective disorder. Clients (N = 232) were assessed for depression, anxiety, elation, cravings, drink and drug intake on admission, discharge, 3 and 6 months post-discharge from the program.
Results: In the overall group there was a reduction in number of drinking days and units per drinking day over the study (p < .01). There was a 71.8% complete abstinent rate at 3 months and 55.8% at 6 months in the depression group, non-significantly greater than for the bipolar group at 64.7% and 54.1% respectively. Gamma GT, MCV and craving scores were significantly reduced over time (p < .01). Mania, depression and anxiety inventory scores fell over time in both groups (p < .01). 15-21-year olds were more severely anxious, had higher illicit drug use, and were more likely to relapse to drug use than older clients. Bipolar 1 clients were significantly more likely than bipolar 2 clients to be on mood stabilisers at all follow-up stages (p < .001).
Limitations: No control group was used.
Conclusions: There is evidence for efficacy of a specifically designed dual diagnosis inpatient treatment program as both depressed and bipolar alcoholics had significant reductions in all measurements of mood, craving, and alcohol/drug consumption by self report and biological markers, suggesting both diagnoses can be effectively treated together
Predictive factors for relapse after an integrated inpatient treatment programme for unipolar depressed and bipolar alcoholics.
AIM: The aim of this study was to examine prospectively examined predictors of relapse in alcohol dependence with comorbid affective disorder.
METHODS: One hundred and eighty-three unipolar depressed or bipolar alcoholics who completed an integrated inpatient treatment programme for dual diagnosis were assessed at baseline, post-treatment discharge and at 3 and 6 months post treatment. Backwards stepwise likelihood ratio multiple logistic regression was used to investigate the impact of multiple covariates on relapse to alcohol in the 0-3- and 3-6-month period post discharge.
RESULTS: The retention rate at 3 months post discharge was 95.3% (177 patients) and at 6 months it was 87.4% (162 patients). Higher level of anxiety at baseline and discharge was significantly associated with relapse at 3, but not at 6 months, in all subjects. Higher baseline alcohol use disorder identification test scores were associated with relapse at 3 and at 6 months. Intention and planning to attend aftercare after discharge from the hospital were associated with non-relapse at 3 and 6 months, respectively. Levels of depression, of elation and of craving at baseline were not significantly predictive of relapse. Those who had relapsed at 3 months were significantly more likely to remain drinking at 6 months. Rehospitalization within the first 3 months post discharge appeared to be protective against further relapse.
CONCLUSIONS: Baseline patient factors, including levels of anxiety, appear to play a significant role in relapse to alcohol in this difficult to treat population
A 5-Year follow-Up of depressed and bipolar patients with alcohol use disorder in an Irish population.
Alcohol use disorders (AUDs) and affective disorders commonly co-occur, and this co-occurrence is mutually detrimental. To date, few long-term outcome studies exist involving patients with these comorbid disorders. We wished to determine treatment outcomes 5Â years after inpatient integrated treatment in patients with these co-occurring disorders, and identify prognostic factors associated with long-term outcome
Gender differences in outcome at 2-year follow-up of treated bipolar and depressed alcoholics.
A total of 189 patients with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for alcohol dependence and either bipolar disorder or depression were recruited, assessed, and assigned to an inpatient treatment unit. Following intensive integrated treatment that was designed to integrate psychotherapy with pharmacotherapy, affective disorder with substance use disorder treatment, and inpatient with outpatient therapy, this population was followed for 2 years after discharge
Prognostic factors of 2-year outcomes of patients with comorbid bipolar disorder or depression with alcohol dependence: importance of early abstinence.
Aims: To investigate the prognostic factors that determine 2-year outcomes in a group of alcohol-dependent patients with depression or bipolar disorder who were treated in an intensive 4-week inpatient programme.
Methods: This was a longitudinal study of an inpatient treatment cohort of dual affective disorder and alcohol-dependent patients, in Dublin, Ireland. Measurements included baseline demographics with follow-up measurements at discharge, 3 months, 6 months and 2 years after treatment, including alcohol consumption, depression, mania/elation, anxiety, craving, drug use and sample blood tests. Factor and regression analysis of multiple variables was carried out to predict outcomes.
Results: A total of 189 participants with alcohol dependence and comorbid depression (n = 101) or bipolar disorder (n = 88) were followed over 2 years after discharge from treatment. Retention rate was 76% over 2 years. Early abstinence (at 6 months) predicted better abstinence overall at 2 years; and bipolar alcoholics had a better outcome in drinks per drinking day than depressed alcoholics at 2 years. Younger participants (age 18–30 years) did relatively worse than middle-age (30–50 years) and older (51 + years) participants in measures of abstinence and number of drinks per drinking day at 2 years; and females did better than males in number of drinks per drinking day at 2 years.
Conclusion: Dual diagnosis of alcohol dependence and depression or bipolar disorder may be treated together with intensive intervention and follow-up, and various prognostic factors including early abstinence emerge over time that influence outcomes over 2 years
Obesogenic island: the financial burden of private transport on low-income households
Background The physical and social environment influences access to a healthy lifestyle, of which transport is one determining factor. This paper
estimates the cost of transport on the island of Ireland.
Methods Budget standards were developed on the basis of costs of baskets of core goods and services required for daily living. The transport
budget was based on the needs of an urban living family. Financial capacity of the family relative to transport basket costs was determined.
Results Transport costs vary depending on family type and car ownership. The motoring costs for a family with two unemployed adults, with a
weekly financial capacity of 388.28E and 427.70E, respectively, for the Republic of Ireland and Northern Ireland, amount to 94.78E and 74.68E,
representing 18 and 10% of the family’s weekly income.
Conclusion The prohibitive costs of private transport present an opportunity for policy makers to consider creating supportive environments
incorporating the more cost-effective and environmentally friendly options of public transport. Without such measures, dependence on private
transport will exacerbate the incidence of food poverty and the health inequalities consequent upon it
