( Diskin and Morris, 2008 ). The aim of this study was to examine the effect of C. burnetii seropositivity by ELISA and complement fixation test (CFT) on early pregnancy and fetal losses in dairy cows between days 29 and 70 of gestation in some Hungarian
The authors screened 34 large cattle herds for the presence of Mycoplasma bovis infection by examining slaughtered cattle for macroscopic lung lesions, by culturing M. bovis from lung lesions and at the same time by testing sera for the presence of antibodies against M. bovis. Among the 595 cattle examined, 33.9% had pneumonic lesions, mycoplasmas were isolated from 59.9% of pneumonic lung samples, and 10.9% of sera from those animals contained antibodiesto M. bovis. In 25.2% of the cases M. bovis was isolated from lungs with no macroscopic lesions. The proportion of seropositive herds was 64.7%. The average seropositivity rate of individuals was 11.3% but in certain herds it exceeded 50%. A probability model was developed for examining the relationship among the occurrence of pneumonia, the isolation of M. bovis from the lungs and the presence of M. bovis specific antibodies in sera.
Background
Ethylenediaminetetraacetic acid (EDTA)-dependent pseudothrombocytopenia is a rare phenomenon. Spurious pseudothrombocytopenia has also been described in other circumstances, while artifactual platelet count in whole blood samples anticoagulated with sodium citrate is an exceptional occurrence.
Case report
In this study, we describe the case of a 44-year-old ostensibly healthy woman who attended the local outpatient clinic for routine laboratory testing, including platelet count in EDTA and sodium citrate, for suspected artifactual pseudothrombocytopenia previously identified in another center. The results of hematological testing on both specimens were essentially normal, except for mild anemia. Nevertheless, the platelet number was 425 × 109/L in K2EDTA and 266 × 109/L (293 × 109/L after correcting for sample dilution) in sodium citrate, respectively. Microscopic revision of blood smears revealed the presence of platelet aggregates and satellitism only in the sodium citrate specimen.
Conclusion
Unlike previous occasional reports of concomitant EDTA- and sodium citrate-dependent pseudothrombocytopenia, we first describe a paradigmatic case of artifactual platelet count attributable to platelet clumping and satellitism, exclusively developing in blood anticoagulated with sodium citrate.
Aims: The present theoretical paper introduces the smartphone technology as a challenge for diagnostics in the study of Internet use disorders and reflects on the term “smartphone addiction.”
Methods: Such a reflection is carried out against the background of a literature review and the inclusion of Gaming Disorder in ICD-11.
Results: We believe that it is necessary to divide research on Internet use disorder (IUD) into a mobile and non-mobile IUD branch. This is important because certain applications such as the messenger application WhatsApp have originally been developed for smartphones and enfold their power and attractiveness mainly on mobile devices.
Discussion and conclusions: Going beyond the argumentation for distinguishing between mobile and non-mobile IUD, it is of high relevance for scientists to better describe and understand what persons are actually (over-)using. This is stressed by a number of examples, explicitly targeting not only the diverse contents used in the online world, but also the exact behavior on each platform. Among others, it matters if a person is more of an active producer of content or passive consumer of social media.
A retrospective study was conducted to investigate the presence of ferlavirus, ball python nidovirus and bacteria in 32 tracheobronchial lavages from ball pythons raised in captivity and affected by respiratory disease. A touchdown reverse transcription polymerase reaction (RT-PCR) was performed to detect ball python nidovirus RNA targeting a 260-bp portion of the ORF1a gene, while a nested RT-PCR was applied to identify RNA targeting the 518-bp ferlavirus partial L gene. RT-PCR positive products were submitted for Sanger’s sequencing and phylogeny reconstruction. Bacteriological examinations were performed to diagnose a possible bacterial involvement. BLAST analysis revealed that the nucleotide sequences of the six (18.8%) RT-PCR positive amplicons were 90–97% identical to the partial sequence of the ORF1a gene of the recently described ball python nidovirus. All tested snakes were negative for ferlavirus. Thirteen out of 32 samples (40.6%) were bacteriologically positive. Respiratory tract diseases can be a substantial problem for snake breeders, considering the rapid transmission of respiratory pathogens. The results and published studies show that ball python nidovirus is circulating in python collections and could be linked to suboptimal management practices. Surveillance programs are desirable as part of the routine snake health assessment. Tracheobronchial lavage is a fast, practical, cost-effective procedure for sample collection.

Background and aims
Unregulated Internet pornography (IP) use is discussed as a clinically significant disorder. Because of its primarily rewarding nature, IP is a predestinated target for addictive behaviors. However, not every user develops an unregulated usage pattern. In fact, most users tend to use IP recreationally. Impulsivity-related constructs have been identified as promoters of addictive behaviors. It is unclear whether these impulsivity-related constructs are specific for unregulated IP use or also play a role in recreational but frequent behaviors. In this study, we investigated impulsive tendencies (trait impulsivity, delay discounting, and cognitive style), craving toward IP, attitude regarding IP, and coping styles in individuals with recreational–occasional, recreational–frequent, and unregulated IP use.
Methods
A total of 1,498 heterosexual males participated in an online survey. Groups of individuals with recreational–occasional use (n = 333), recreational–frequent use (n = 394), and unregulated use (n = 225) of IP were identified by screening instruments.
Results
Craving and attitude regarding IP as well as delay discounting and cognitive and coping styles differed between groups. Individuals with unregulated use showed the highest scores for craving, attentional impulsivity, delay discounting, and dysfunctional coping, and lowest scores for functional coping and need for cognition. Recreational–frequent users had the most positive attitude toward IP. Motor and non-planning impulsivity did not differ between groups.
Discussion and conclusions
The results indicate that some facets of impulsivity and related factors such as craving and a more negative attitude are specific for unregulated IP users. The results are also consistent with models on specific Internet use disorders and addictive behaviors.
Abstract
Background and aims
Social-networks-use disorder is discussed as a potential further type of disorders due to addictive behaviors. Theoretical models assume cue-induced craving and disadvantageous decision making to be relevant mechanisms. This study investigates if the presentation of social-networks-related cues interferes with decision making under ambiguity.
Methods
Craving was induced with a cue-reactivity paradigm and assessed with a visual analogue scale. Participants (N = 146) played a modified Iowa Gambling Task with social-networks-related cues and neutral cues presented on the advantageous and disadvantageous decks respectively, or vice versa. Symptoms of social-networks-use disorder were measured with a modified version of the short Internet Addiction Test.
Results
Overall, participants chose options with neutral cues more often than those with social-networks-related cues, even if it was disadvantageous. There was a significant interaction between decision-making performance and Iowa Gambling Task condition in predicting symptom severity. The results indicate that choosing decks with social-networks-related cues even if it was disadvantageous is associated with higher tendencies towards a social-networks-use disorder. The interaction with cue-induced craving did not explain further variance.
Discussion and Conclusions
The results highlight the relevance of cue reactivity, decision making, and their interaction as potential mechanisms explaining tendencies towards a social-networks-use disorder. Decision making was influenced by affective responses, which could result in a higher risk of a potential addictive behavior. This is consistent with the findings from addiction research and with theoretical approaches assuming an imbalance between affective and cognitive processes in addictive behaviors.
Abstract
Background and aims
With the inclusion of gaming disorder in the ICD-11, diagnostic criteria were introduced for this relatively new disorder. These criteria may also be applied to other potential specific Internet-use disorders, which may be classified in ICD-11 as other disorders due to addictive behaviors, such as online buying-shopping disorder, online pornography-use disorder, social-networks-use disorder, and online gambling disorder. Due to the heterogeneity in existing instruments, we aimed to develop a consistent and economic measure of major types of (potential) specific Internet-use disorders based on ICD-11 criteria for gaming disorder.
Methods
The new 11-item Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) measures five behavioral addictions with the same set of items by following the principles of WHO’s ASSIST. The ACSID-11 was administered to active Internet users (N = 985) together with an adaptation of the Ten-Item Internet Gaming Disorder Test (IGDT-10) and screeners for mental health. We used Confirmatory Factor Analyses to analyze the factor structure of ACSID-11.
Results
The assumed four-factorial structure was confirmed and was superior to the unidimensional solution. This applied to gaming disorder and to the other specific Internet-use disorders. ACSID-11 scores correlated with IGDT-10 as well as with the measures of psychological distress.
Discussion and Conclusions
The ACSID-11 seems to be suitable for the consistent assessment of (potential) specific Internet-use disorders based on ICD-11 diagnostic criteria for gaming disorder. The ACSID-11 may be a useful and economic instrument for studying various behavioral addictions with the same items and improving comparability.
