Aleocharine rove beetles of New Hampshire, USA: new taxa and new records (Coleoptera, Staphylinidae, Aleocharinae).

Based on the specimens housed primarily in the University of New Hampshire Insect Collection (UNH) and the Canadian National Collection (CNC), we present here a comprehensive faunal review of aleocharine beetles of the state and provide new distribution and natural history data. We report 252 species from New Hampshire belonging to some 74 genera in 15 tribes; 159 of these constitute new New Hampshire state records (NSR), of which 37 (excluding new species and including 1 New York record) constitute new country distribution records (NCR) for the USA. In addition, we provide 36 new state records for ME, with 5 of these species not yet known from NH, seven new state records for MA, two new state records for PA and VT, and one each for CT, DE, MI, NC, NY (also a NCR), OH, and OK. One new genus, Belladonna Klimaszewski and Chandler is erected, and nine species are described as new to science (alphabetical order): Agaricomorpha hampshirensis Klimaszewski and Chandler, sp. n., Atheta ellisi Klimaszewski and Chandler sp. n, Atheta monroe Klimaszewski and Chandler, sp. n., Atheta struyvei Klimaszewski and Chandler sp. n, Belladonna barryi Klimaszewski and Chandler, sp. n., Belladonna fortieri Klimaszewski and Chandler, sp. n., Colusa smetanai Klimaszewski and Chandler, sp. n., Philhygra pinkhami Klimaszewski and Chandler sp. n., and P. pseudomagniceps Klimaszewski and Chandler, sp. n. Undescribed females of Aleochara daviesi Klimaszewski and Brunke, and Silusa langori Klimaszewski, are described and illustrated. Illustrations of Atheta (Tetropla) tubericauda Bernhauer are provided for the first time, based on a male from New Hampshire. A new combination is proposed for Atheta (Dimetrota) mcalpinei Klimaszewski and Webster.

A Prospective Real-World Study Exploring Associations Between Passively Collected Tracker Data and Headache Burden Among Individuals with Tension-Type Headache and Migraine.

INTRODUCTION: Prevalence and burden of headache disorders in real-world settings is relatively unstudied. We explored the associations between passively collected activity data, headache burden, and quality of life in headache sufferers. METHODS: Data from wearable activity tracking devices and daily short questionnaires were collected over 12 weeks to assess occurrence of headache, activity, quality of life and self-rated health. Variables were analyzed using a series of mixed-effects models and stratified based on headache type. Multiple linear and logistic regressions were used to analyze treatment preferences. RESULTS: Behaviors inferred from activity tracker data suggested that individuals slept more, had reduced physical activity, and had lower maximum heart rate on days with headache. As headache-specific impact on quality of life increased, activity and maximum heart rate decreased and sleep increased. Headache days with higher self-rated health were associated with less napping, higher step count and maximum heart rate, correlating with increased activity. Migraineurs experienced greater burden in everyday life compared with tension-type headache sufferers. CONCLUSION: This study adds to existing evidence that activity trackers can be used to quantify headache burden in real-world settings and aid in understanding symptom management.

Multinational descriptive analysis of the real-world burden of headache using the Migraine Buddy application.

BACKGROUND AND PURPOSE: A large proportion of headache sufferers do not routinely seek medical care. App-based technologies permit the collection of real-world data over time and between countries that can help assess true burden of headache. This study used a mobile phone application to collect information on the real-world burden of self-diagnosed headache and to describe its impact on daily life in headache sufferers who do not routinely seek medical advice. METHODS: This retrospective, non-interventional, cross-sectional study analysed self-reported data from users of the 'Migraine Buddy' app. The main objective was to describe self-reported characteristics of headache and migraine (triggers, duration, frequency), treatment patterns and impact on daily activity in headache sufferers from Australia, Brazil, France, Germany and Japan. Data including demographics, self-diagnosed episode type (headache/migraine), duration, potential triggers and impact on daily activity are reported. All analyses were exploratory and performed per country. RESULTS: Self-reported data were collected from 60,474 users between August 2016 and August 2018. Approximately 90% of users were females; >60% were aged 24-45 years. Over one-third of users reported having two to five episodes of headache or migraine per month; impact included impaired concentration, being slower and missing work or social activities. Variations across countries were observed; within countries, episode characteristics were very similar for self-diagnosed headache versus migraine. CONCLUSIONS: Headache tracking was used to describe the experience, impact and self-management approaches of migraine and headache sufferers in a real-world setting. Headache disorders present a range of important issues for patients that deserve more study and reinforce the need for better approaches to management.

Predictors of pain and mobility disability in the hypermobile Ehlers-Danlos syndrome.

Aim: Among the Ehlers-Danlos syndromes, the hypermobile subtype (hEDS) is the most common. The variety, accumulation and duration of the painful symptoms make hEDS a chronic and highly disabling condition. Identifying drivers of pain and mobility disability in hEDS is necessary to provide adapted prevention and intervention programs.Methods: A cross-sectional sample of 75 adults with hEDS according to Villefranche criteria (67 women; 36 years, SD = 11.2) responded to self-assessment questionnaires regarding psychological (negative thoughts and emotions), health (pain, fatigue, diagnostic delay, body mass index, and mobility disability) and socio-demographic variables.Results: Forty-three percent of the participants suffer from severe pain, and two thirds suffer from a high level of mobility disability. Multivariate analyses show that delay of diagnosis, being professionally active and thoughts of helplessness are variables that increase the likelihood of severe pain, whereas age, fatigue, and body mass index predict mobility disability.Conclusion: These results confirm previous research concerning the high disease burden observed in hEDS patients, and highlight the importance of multidisciplinary management that includes nutritional and psychological advice to address this pathology. Increasing awareness of the clinical aspects of hEDS among physicians is necessary to reduce diagnostic delay and minimize negatives outcomes.Implications for RehabilitationA high proportion of patients with hypermobile Ehlers-Danlos syndrome suffer from severe pain (>42%) and a high level of mobility disability (>65%).Different psychosocial and health variables predict pain and mobility disability in patients with hypermobile Ehlers-Danlos syndrome.Awareness concerning the clinical picture of hypermobile Ehlers-Danlos syndrome among health care professionals is necessary to reduce diagnosis delay and the burden of the disease.

Species review of the genus Boreophilia Benick from North America (Coleoptera, Staphylinidae, Aleocharinae, Athetini): Systematics, habitat, and distribution.

Fourteen species of the genus Boreophilia Benick are now recognized in North America. Boreophiliainsecuta (Eppelsheim), reported by Lohse (1990) from North America, is a misidentification of a new species, which is described here as B.neoinsecuta Klimaszewski, sp. n., and the true B.insecuta (Epp.) does not occur in North America. An additional new species is found in Alaska, and described as B.beringi Klimaszewski & Brunke, sp. n. The following three species are synonymized (second name being valid): Boreophiliaherschelensis Klimaszewski & Godin, 2012, with Boreophiliavega (Fenyes, 1920); Boreophiliamanitobensis Lohse, 1990, with B.caseyi Lohse, 1990; and B.angusticornis (Bernahuer, 1907) with B.subplana (J Sahlberg, 1880), based on study of genital structures and external morphology. Athetagelida J Sahlberg, 1887, and Athetamunsteri Bernhauer, 1902, considered as Boreophilia in recent publications, are transferred to the genus Atheta Thomson, subgenus Dimetrota. Boreostibapiligera (J Sahlberg) is transferred to Boreophilia based on morphology and the results of our phylogenetic analysis. Boreophilianearctica is recorded from Alberta and B.nomensis is recorded from British Columbia for the first time. Each valid species is illustrated by color image of habitus, and black and white images of genitalia and tergite and sternite VIII. A new key to all Nearctic species of the genus is provided. DNA barcode data were available for nine of the 14 species, which we downloaded, analyzed, and used as additional evidence for the taxonomic conclusions reached herein.

Low- and high-anxious hypermobile Ehlers-Danlos syndrome patients: comparison of psychosocial and health variables.

Despite the frequent co-ocurrence of hypermobile Ehler-Danlos syndrome (hEDS) and pathological anxiety, little is known about the psychosocial and health implications of such comorbidity. Our aim was to explore the association between high levels of anxiety and psychosocial (catastrophizing, kinesiophobia, somatosensory amplification, social support and functioning), health (pain, fatigue, BMI, tobacco/alcohol use, depression, diagnosis delay, general health), and sociodemographic factors in people with hEDS. In this cross-sectional study, 80 hEDS patients were divided into two groups according to self-reported anxiety levels: low and high. Psychosocial, sociodemographic and health variables were compared between the groups. Forty-one participants reported a high level of anxiety (51.2%). No differences were found in the sociodemographic variables between high-anxious and low-anxious patients. The percentage of participants with severe fatigue and high depressive symptomatology was significantly higher in the high-anxious group (80.5 vs 56.4; 26.8 vs 12.8%, respectively). High-anxious hEDS patients also showed significantly higher levels of pain catastrophizing, somatosensory amplification as well as a poorer social functioning and general health. Multivariate analyses showed that somatosensory amplification, pain catastrophizing and poor social functioning are variables that increase the probability of belonging to the high-anxious group. Despite limitations, this first study comparing high-anxious versus low-anxious hEDS patients with respect to health aspects, highlight the importance of considering the psychosocial factors (many susceptible to modification), to improve the adjustment to this chronic condition and provide support to those affected through a biopsychosocial approach.

First record of Thecturota tenuissima Casey from Canada (Coleoptera, Staphylinidae, Aleocharinae).

Review of Canadian species of the genus Mocyta Mulsant & Rey (Coleoptera, Staphylinidae, Aleocharinae), with the description of a new species and a new synonymy.

Six species of the genus Mocyta Mulsant & Rey are reported from Canada: Mocytaamblystegii (Brundin), Mocytabreviuscula (Mäklin), Mocytadiscreta (Casey), Mocytafungi (Gravenhorst), Mocytaluteola (Erichson), and Mocytasphagnorum Klimaszewski & Webster, sp. n. New provincial and state records include: Mocytabreviuscula - Saskatchewan and Oregon; Mocytadiscreta - Quebec, Ontario and Saskatchewan; Mocytaluteola - New Brunswick, Quebec, Ontario, Massachusetts and Minnesota; and Mocytafungi - Saskatchewan. Mocytasphagnorum is described from eastern Canada from specimens captured in Newfoundland, New Brunswick, Quebec and Ontario. Mocytanegligens Mulsant and Rey, a native European species suspected of occurring in Canada, is excluded from the Nearctic fauna based on comparison of European types with similarly coloured Canadian specimens, which are now identified as Mocytaluteola. The European species, Mocytagilvicollis (Scheerpeltz), is synonymized with another European nominal species, Mocytanegligens, based on examination of type material of the two species. Lectotypes are designated for Eurypronotadiscreta Casey, Athetagilvicollis Scheerpeltz, Homalotaluteola Erichson, Colpodotanegligens Mulsant and Rey, Acrotonaprudens Casey and Dolosotaredundans Casey. The latter species is here synonymized with Mocytaluteola. A review of the six Nearctic species is provided, including keys to species and closely related genera, colour habitus images, images of genitalia, biological information and maps of their distributions in Canada.

Review of Canadian species of the genera Gnathusa Fenyes, Mniusa Mulsant & Rey and Ocyusa Kraatz (Coleoptera, Staphylinidae, Aleocharinae).

Four species of Gnathusa Fenyes (G. alfacaribou Klimaszewski & Langor, G. caribou Lohse, G. eva Fenyes, and G. tenuicornis Fenyes) occur in the Nearctic and in Canada. Three species of Ocyusa Kraatz (O. asperula Casey, O. californica Bernhauer, O. canadensis Lohse), and three species of Mniusa Mulsant and Ray (M. minutissima (Klimaszewski & Langor), M. yukonensis (Klimaszewski & Godin), and M. odelli Klimaszewski & Webster, sp. n.), are known from the Nearctic and all but O. californica occur in Canada. The recently described Gnathusa minutissima Klimaszewski and Langor and Ocyusa yukonensis Klimaszewski and Godin, are transferred here to the genus Mniusa Mulsant & Rey. New provincial and state records are reported for: G. eva (Alberta), G. tenuicornis (Alberta, Oregon, and New Brunswick), O. canadensis (New Brunswick and Newfoundland), M. minutissima (New Brunswick), and M. yukonensis (Nova Scotia, New Brunswick, Quebec, and British Columbia). The female of M. yukonensis was discovered and is illustrated for the first time. The genus Mniusa is reported for the first time from Canada and represents the first confirmed generic record for North America. Keys for identification of all Canadian species, images of body and genital structures, maps showing distribution mainly in Canada, and new bionomics data are provided.

Molecular and microscopic analysis of the gut contents of abundant rove beetle species (Coleoptera, Staphylinidae) in the boreal balsam fir forest of Quebec, Canada.

Experimental research on beetle responses to removal of logging residues following clearcut harvesting in the boreal balsam fir forest of Quebec revealed several abundant rove beetle (Staphylinidae) species potentially important for long-term monitoring. To understand the trophic affiliations of these species in forest ecosystems, it was necessary to analyze their gut contents. We used microscopic and molecular (DNA) methods to identify the gut contents of the following rove beetles: Atheta capsularis Klimaszewski, Atheta klagesi Bernhauer, Oxypoda grandipennis (Casey), Bryophacis smetanai Campbell, Ischnosoma longicorne (Mäklin), Mycetoporus montanus Luze, Tachinus frigidus Erichson, Tachinus fumipennis (Say), Tachinus quebecensis Robert, and Pseudopsis subulata Herman. We found no apparent arthropod fragments within the guts; however, a number of fungi were identified by DNA sequences, including filamentous fungi and budding yeasts [Ascomycota: Candida derodonti Suh & Blackwell (accession number FJ623605), Candida mesenterica (Geiger) Diddens & Lodder (accession number FM178362), Candida railenensis Ramirez and Gonzáles (accession number JX455763), Candida sophie-reginae Ramirez & González (accession number HQ652073), Candida sp. (accession number AY498864), Pichia delftensis Beech (accession number AY923246), Pichia membranifaciens Hansen (accession number JQ26345), Pichia misumaiensis Y. Sasaki and Tak. Yoshida ex Kurtzman 2000 (accession number U73581), Pichia sp. (accession number AM261630), Cladosporium sp. (accession number KF367501), Acremoniumpsammosporum W. Gams (accession number GU566287), Alternaria sp. (accession number GU584946), Aspergillus versicolor Bubak (accession number AJ937750), and Aspergillusamstelodami (L. Mangin) Thom and Church (accession number HQ728257)]. In addition, two species of bacteria [Bradyrhizobium japonicum (Kirchner) Jordan (accession number BA000040) and Serratia marcescens Bizio accession number CP003942] were found in the guts. These results not only provide evidence of the consumer-resource relations of these beetles but also clarify the relationship between rove beetles, woody debris and fungi. Predominance of yeast-feeding by abundant rove beetles suggests that it may play an important role in their dietary requirements.
