AbstractAnthropogenic stressors can alter the structure and functioning of infaunal communities, which are key drivers of the carbon cycle in marine soft sediments. Nonetheless, the compounded effects of anthropogenic stressors on carbon fluxes in soft benthic systems remain largely unknown. Here, we investigated the cumulative effects of ocean acidification (OA) and hypoxia on the organic carbon fate in marine sediments, through a mesocosm experiment. Isotopically labelled macroalgal detritus (13C) was used as a tracer to assess carbon incorporation in faunal tissue and in sediments under different experimental conditions. In addition, labelled macroalgae (13C), previously exposed to elevated CO2, were also used to assess the organic carbon uptake by fauna and sediments, when both sources and consumers were exposed to elevated CO2. At elevated CO2, infauna increased the uptake of carbon, likely as compensatory response to the higher energetic costs faced under adverse environmental conditions. By contrast, there was no increase in carbon uptake by fauna exposed to both stressors in combination, indicating that even a short‐term hypoxic event may weaken the ability of marine invertebrates to withstand elevated CO2 conditions. In addition, both hypoxia and elevated CO2 increased organic carbon burial in the sediment, potentially affecting sediment biogeochemical processes. Since hypoxia and OA are predicted to increase in the face of climate change, our results suggest that local reduction of hypoxic events may mitigate the impacts of global climate change on marine soft‐sediment systems.

AimThe SARC‐F is a useful clinical index for sarcopenia screening; however, this measure has low sensitivity. Furthermore, this tool has never been validated on community‐dwelling older Japanese adults. The goal of the present study was to validate a Japanese version of the SARC‐F and confirm its suitability for Japanese samples.MethodsParticipants were 734 community‐dwelling older adults in the Itabashi Ward, Japan. Bioimpedance measures, walking speed, grip strength and instrumental activities of daily living (IADL) were measured. Sarcopenia was defined using the European Working Group on Sarcopenia in Older People, the Asian Working Group for Sarcopenia criteria and Japanese‐adjusted Asian Working Group for Sarcopenia. SARC‐F receiver operating characteristic curves for each sarcopenia measure were used to evaluate diagnostic accuracy. Physical functioning, IADL and sarcopenia screening tools were compared with the SARC‐F.ResultsA total of nine men (3.1%) and 15 women (3.4%) were classified into a SARC‐F sarcopenia group. The sarcopenia group had lower physical functioning and Mini Sarcopenia Risk Assessment scores and higher frailty status than the control group. The Cronbach's alpha for the SARC‐F was 0.610, suggesting insufficient internal consistency. SARC‐F scores were related to physical functioning, IADL, and Mini Sarcopenia Risk Assessment scores. Receiver operating characteristic analyses of the SARC‐F based on each criterion showed low sensitivity, but high specificity.ConclusionsThe Japanese version of the SARC‐F appears to be a useful index for reflecting physical functioning and IADL. However, it is necessary to further determine whether this tool is useful for detecting sarcopenia among community‐dwelling older adults. Geriatr Gerontol Int 2019; 19: 1172–1178.

AimIn heart failure with preserved ejection fraction (HFpEF), it is unclear which factors on admission are correlated with long stays. In contrast, acute decompensated heart failure (ADHF) in older patients is associated with a high risk of a long stay. To manage older ADHF patients with HFpEF, it is important to reveal the risk factors for a long stay on admission.MethodsWe enrolled consecutive older patients (aged >75 years) with HFpEF (ejection fraction ≥50%) who were admitted to control ADHF from May 2014 to April 2016 using the acute heart failure registry in Osaka Rosai Hospital. We compared various factors, including age; sex; body mass index; heart rate; systolic blood pressure (SBP); atrial fibrillation; atherosclerotic risk factors, including dyslipidemia, diabetes mellitus, hypertension, smoking and chronic kidney disease; laboratory data, including brain natriuretic peptide and albumin; and medications, including loop diuretics, on pre‐admission between short‐stay (<14 days) and long‐stay groups.ResultsThe long‐stay group consisted of 122 patients (59.5%). Multivariate analysis showed that male sex, SBP and albumin were independent predictors for long stays. According to the classification and regression tree and receiving operating characteristic curve analysis, all three factors on admission, including male sex, relatively low SBP (<155 mmHg) and hypoalbuminemia (<3.4 g/dL) could well predict the patients that would require long stays (area under curve 0.738).ConclusionsAmong older ADHF patients with HFpEF, male patients with relatively low SBP and hypoalbuminemia on admission should initially undergo more intensive management to reduce the length of stay.

BackgroundMost of the clinical characteristics of cluster headache (CH) have been established through the observation of men with CH. Epidemiological data of CH in women are scarce especially in the Asian population. Here, we sought to assess the prevalence and clinical characteristics of women with CH in comparison to men in a prospective CH registry.MethodsData used in this study were obtained from the Korean Cluster Headache Registry, a prospective, cross‐sectional, multicenter headache registry that collected data from consecutive patients diagnosed with CH. Demographics and clinical characteristics were compared between the sexes.ResultsIn total, 250 patients were enrolled in this study; 41 (16.4%) were women (male to female ratio 5.1:1). Mean age of onset did not differ between women and men (30.7 ± 15.5 vs 29.0 ± 11.1 years). The clinical features of CH in women and men were similar, with no differences in pain severity, duration, and attack frequency. Among autonomic features, facial and forehead sweating was significantly rare in women (4.9%) compared to men with CH (33.0%). Headache‐related disability assessed by Headache Impact Test‐6 did not differ between the sexes; however, depression scale assessed by Patients Health Questionnaire‐9 (11.0 ± 8.5 vs 7.0 ± 5.8, P = .009) and stress (Perceived Stress Scale 4, 7.5 ± 3.4 vs 6.4 ± 3.0, P = .045) were significantly higher in women with CH.ConclusionsAlthough decreasing male preponderance was suggested in recent Western CH studies, CH in women is still far less prevalent than in men in the Korean population. Clinical and demographic characteristics were similar between the sexes. However, psychiatric comorbidities might be highly associated in women with CH.

ObjectiveTo report a case of petrous apicitis that manifested as chronic migraine without aura and to discuss the pathophysiological mechanisms behind this presentation.BackgroundPetrous apicitis is a rare complication of acute otitis media with varied clinical presentations that stem from the close proximity of the petrous apex to numerous neurovascular structures. Headache is among the common symptoms of petrous apicitis.MethodsA case of new onset headache in the setting of petrous apicitis with symptomatic response to antibiotic therapy was reported. We provided a brief review of peripheral pathophysiological mechanisms of migraine and correlated to mechanism of headache in petrous apicitis.ResultsA 65‐year‐old man with chronic otitis externa/media presented with ongoing headache fulfilling International Classification of Headache Disorders 3rd edition (ICHD‐3) criteria for chronic migraine without aura that persisted despite undergoing right mastoidectomy and tympanoplasty with multiple courses of oral antibiotic therapy for his chronic otitis. MRI brain revealed petrous apicitis, otomastoiditis, and clival osteomyelitis. His imaging findings improved and his migraine‐like headache completely resolved after treatment with a prolonged course of antibiotics.ConclusionsPetrous apicitis can present as a headache with features of migraine, and in this case in particular, as chronic migraine without aura. The pathophysiological mechanisms that may underlie the generation of migraine‐like headache in petrous apicitis may include the activation of nociceptive fibers within the periosteum of the petrous apex and clivus whose cell bodies originate in the trigeminal ganglion and upper cervical dorsal root ganglia. By treating the peripheral pathology, resolution of the headache may be achieved.
Development and morphology of ciliary urns in the sea cucumber Synaptula hydriformis (Echinodermata: Holothuroidea)
Authors: Curtis Michelle D. , Turner Richard L. 
Published: September 2019

AbstractSea cucumbers (holothuroids) lack the only known echinoderm immune organ, the axial organ. Holothuroids of the families Synaptidae and Chiridotidae have coelomic organs, known as ciliary urns, that gather and excrete waste and, therefore, might function in immunity. Although ciliary urns are widely reported and illustrated in the literature, the process and histology of urn development remain unknown. Development and structure of ciliary urns were examined in Synaptula hydriformis using scanning electron, brightfield, and scanning laser confocal microscopy. Mature urns occurred on all three mesenteries in 10‐tentacled young and later growth stages, and developing urns were found in post‐pentactulae, 10‐tentacled young, and released juveniles. Developing urns were circular clusters of ciliated collar cells protruding from the mesentery. The cells increased in number to form the sessile cushion stage with a shallow lumen. The subsequent spoon‐shaped stage had a stalk and a deepened lumen with an extensive ciliary field where coelomocytes began to accumulate. Mature urns had a thin stalk and cornucopia‐shaped body with an abluminal epithelium of squamous cells and an adluminal epithelium of densely packed ciliated collar cells. Cell boundaries of the rim of mature urns and of the stalk and body of developing urns were outlined on one or both sides by microvilli and an elevated cell membrane. Ciliary urns resembling the cushion‐stage urns of S. hydriformis have been described in the sea star Archaster typicus. If urns in these groups are homologous, it is likely that cushion urns are plesiomorphic and that they are present and have been overlooked in other echinoderms.

AbstractThe objectives of this study were to compare different models for analysing body weight (BW) and average daily feed intake (ADFI) data collected during a 70‐day feedlot test period and to explore whether genetic parameters change over time to evaluate the implications of selection response. (Co)variance components were estimated using repeatability and random regression models in 2,071 Angus steers. Models included fixed effects of contemporary group, defined as herd–year–observation_date–age, with additive genetic and permanent environmental components as random effects. Models were assessed based on the log likelihood, Akaike's information criterion and the Bayesian information criterion. For both traits, random regression models (RRMs) presented a better fit, indicating that genetic parameters change over the test period. Using a two‐trait RRM, the heritability from day 1 up to day 70 for BW increased from 0.40 to 0.50, while for ADFI, it decreased from 0.44 to 0.33. The genetic correlation increased from 0.53 at day 1 up to 0.79 at day 70. Selection based on an index assuming no change in genetic parameters would yield a 2.78%–3.13% lower selection response compared to an index using parameters estimated with RRMs and assuming these genetic parameters are correct. Results imply that it may be beneficial to implement RRMs to account for the change of parameters across the feedlot period in feed efficiency traits.
Goals, Conflict, Politics, and Performance of Cross‐Functional Sourcing Teams—Results from a Social Team Experiment
Authors: Franke Henrik , Foerstl Kai 
Published: September 2019

Strategic sourcing is carried out in cross‐functional teams to account for the complexity and multidimensionality of modern procurement decisions. However, such teams not only enable the integration of distinct interdependent skill sets and viewpoints, they are also characterized by functional goal misalignment. We focus on the resulting behavioral challenges, namely conflict and politics, and their effects on team satisfaction and rationality, which ultimately leads to observed outcomes. We test our hypotheses in a structural equation model based on data gathered from 468 participants in a social team experiment. We find a mediated effect of goal misalignment on political behavior via two types of team conflict. Political behavior, in turn, obstructs rational team sourcing decisions and reduces team members’ satisfaction with the process. Our study indicates that behavioral challenges in the framework of Organizational Buying Behavior not only co‐occur but affect each other via mediation. Hence, managers need to closely monitor the escalation chains’ origin, task conflict, which constitutes a necessary condition for further emotional dissent and political biasing. We contribute to the understanding of the challenges in cross‐functional sourcing teams, thereby providing advice to executives in their pursuit to rationalize and improve sourcing team decisions and their outcomes.
Recurrent persistent atrial fibrillation after effective pulmonary vein isolation: What else?
Authors: Della Rocca Domenico G. , Natale Andrea 
Published: September 2019

AbstractPulmonary vein isolation (PVI) is the mainstay of every atrial fibrillation (AF) ablation procedure. However, it is still debated in the literature whether PVI alone is sufficient to achieve long‐term freedom from atrial tachyarrhythmias in patients with non‐paroxysmal AF. Hereby, we discuss the hypothetical clinical scenario of a patient with AF relapse 6 months after PVI in whom all pulmonary veins are electrically silent at the time of repeat ablation.

AbstractBackgroundUltrasound (US) is a real‐time non‐invasive technique that has been demonstrated to support an early diagnosis and a more precise assessment of hidradenitis suppurativa (HS).ObjectivesTo compare the clinical and US evaluation of a series of HS patients.Methods434 HS patients (259 F, 175 M; mean age 33.82 ±13.31 years) observed across 19 Italian dermatology centres [members of the Italian Ultrasound Working Group (IUWG)] were enrolled in a retrospective study. Clinical staging was obtained by the Hidradenitis Suppurativa Physician's Global Assessment score (HS‐PGA), while the ultrasonographic staging was determined by the US HS‐PGA, based on the same scores as clinical HS‐PGA but performed with the aid of US.ResultsAt the end of the study, the mean clinical and US HS‐PGA scores were 2.70 and 2.92, respectively. Direct comparison of clinical and ultrasonographic assessment revealed that a higher proportion of patients was classified as having moderate and very severe disease by US. In particular, 117 patients (26.96%) had a worse classification by US HS‐PGA compared to clinical assessment.ConclusionOur findings confirm that the use of clinical grading only to assess HS severity may underestimate the real disease severity. US examination can be considered an essential non‐invasive imaging tool available to dermatologists for a more accurate diagnosis, staging, treatment planning and monitoring of HS and should be included in the pathway to an optimal standard of care of HS.
Steatocystoma multiplex suppurativa associated with hidradenitis suppurativa successfully treated with adalimumab

Published: September 2019

AbstractSteatocystoma multiplex (SM) is a rare autosomal dominant disease characterized by multiple asymptomatic intradermal true sebaceous cysts of variable size. These lesions may occasionally rupture, become inflamed, painful and heal with scarring [SM suppurativa (SMS)], thus sharing overlapping features with hidradenitis suppurativa (HS). The question of whether SMS simply mimics HS or if the two diseases may be associated remains open. We report three patients (2 M/1 F; age: 47, 27 and 40 years) affected by SMS showing inflammatory lesions on the areas typically affected by HS. Repeated skin biopsy from each patient showed true sebaceous cysts in some specimens and findings compatible with HS, without sebaceous glands evidence in others, supporting coexistence of the two diseases. Adalimumab at the initial dose of 160 mg (day 1), followed by 80 mg (day 15), and maintained at the dose of 40 mg every week from day 29 on, improved both HS and SMS lesions, including also non‐inflammatory cystic lesions.
The patient journey: a voyage from diagnosis to hidradenitis suppurativa multidisciplinary unit
Authors: Chiricozzi A. , Micali G. , Veraldi S. 
Published: September 2019

AbstractBackgroundHidradenitis suppurativa (HS) is an inflammatory, recurrent and debilitating chronic skin disease that is often worsened by comorbidities, with a destructive impact on the social and working life of the patient. The low awareness of patients and clinicians regarding HS, together with weak coordination between specialists who manage the clinical care of these patients, may result in a burdening diagnostic and therapeutic delay, lowering efficacy of therapies and worsening prognosis and patients' QoL.ObjectivesTo rule out these critical aspects, a HS‐Multidisciplinary Unit with a hierarchical organization is proposed.MethodsBased on previously published models of a multidisciplinary unit, a hierarchical structure of a HS‐dedicated multidisciplinary unit was designed.ResultsIn this model, an operational core constituted by four healthcare professionals constantly working as team, is supported by a large panel of consultants, local dermatologists and general practitioners, helping in HS patient management.ConclusionsThis standardization would imply an optimization of professional resources, an amelioration of patient’s quality of life, and a shortening of patient journey.
Brownish macules on the right temple
Authors: Liu Cong , Ding Li‐Juan , Tan Cheng 
Published: September 2019

SummaryA 28‐year‐old male presented with multiple pigmented macules on his right temple over two years. Physical examination showed multiple, discrete, brownish macules on his right temple. These lesions coalesced into reticular shape. Histology of the lesion demonstrated a deposit of eosinophilic acellular material in the dermal papillae. These features were consistent with macular amyloidosis (MA). Macular amyloidosis typically presented over the legs, the arms, and the upper back. We present this patient of MA involving the temple areas, which, to the best of our knowledge, has not previously been reported to occur in this region.
Image‐based crack assessment of bridge piers using unmanned aerial vehicles and three‐dimensional scene reconstruction

Published: September 2019

AbstractCrack assessment of bridge piers using unmanned aerial vehicles (UAVs) eliminates unsafe factors of manual inspection and provides a potential way for the maintenance of transportation infrastructures. However, the implementation of UAV‐based crack assessment for real bridge piers is hindered by several key issues, including the following: (a) both perspective distortion and the geometry distortion by nonflat structural surfaces usually appear on crack images taken by the UAV system from the pier surface; however, these two kinds of distortions are difficult to correct at the same time; and (b) the crack image taken by a close‐range inspection flight UAV system is partially imaged, containing only a small part of the entire surface of the pier, and thereby hinders crack localization. In this paper, a new image‐based crack assessment methodology for bridge piers using UAV and three‐dimensional (3D) scene reconstruction is proposed. First, the data acquisition of UAV‐based crack assessment is discussed, and the UAV flight path and photography strategy for bridge pier assessment are proposed. Second, image‐based crack detection and 3D reconstruction are conducted to obtain crack width feature pair sequences and 3D surface models, respectively. Third, a new method of projecting cracks onto a meshed 3D surface triangular model is proposed, which can correct both the perspective distortion and geometry distortion by nonflat structural surfaces, and realize the crack localization. Field test investigations of crack assessment of a real bridge pier using a UAV are carried out for illustration, validation, and error analysis of the proposed methodology.
