Hemispheric brain asymmetry differences in youths with attention-deficit/hyperactivity disorder.

IntroductionAttention-deficit hyperactive disorder (ADHD) is the most common neurodevelopmental disorder in children. Diagnosis is currently based on behavioral criteria, but magnetic resonance imaging (MRI) of the brain is increasingly used in ADHD research. To date however, MRI studies have provided mixed results in ADHD patients, particularly with respect to the laterality of findings.MethodsWe studied 849 children and adolescents (ages 6–21 y.o.) diagnosed with ADHD (n = 341) and age-matched typically developing (TD) controls with structural brain MRI. We calculated volumetric measures from 34 cortical and 14 non-cortical brain regions per hemisphere, and detailed shape morphometry of subcortical nuclei. Diffusion tensor imaging (DTI) data were collected for a subset of 104 subjects; from these, we calculated mean diffusivity and fractional anisotropy of white matter tracts. Group comparisons were made for within-hemisphere (right/left) and between hemisphere asymmetry indices (AI) for each measure.ResultsDTI mean diffusivity AI group differences were significant in cingulum, inferior and superior longitudinal fasciculus, and cortico-spinal tracts (p < 0.001) with the effect of stimulant treatment tending to reduce these patterns of asymmetry differences. Gray matter volumes were more asymmetric in medication free ADHD individuals compared to TD in twelve cortical regions and two non-cortical volumes studied (p < 0.05). Morphometric analyses revealed that caudate, hippocampus, thalamus, and amygdala were more asymmetric (p < 0.0001) in ADHD individuals compared to TD, and that asymmetry differences were more significant than lateralized comparisons.ConclusionsBrain asymmetry measures allow each individual to serve as their own control, diminishing variability between individuals and when pooling data across sites. Asymmetry group differences were more significant than lateralized comparisons between ADHD and TD subjects across morphometric, volumetric, and DTI comparisons.

The article considers criterion-parametrical aspects of formedness of students-philologists’ cross-cultural competence. There four criteria of formedness of students-philologists’ cross-cultural competence are established as: motivational and axiological, cognitive, operational, behavioural and activity. The main parameters of motivational and axiological criterion are: formedness of cognitive, professional and social motives, according to which one becomes aware of the significance of the material studied and possible ways of its application; positive / neutral / negative attitude to cultural discrepancies; estimation of other culture (following / ignoring stereotypes or prejudices). Cognitive criterion involves: knowledge of phonetic, lexical, grammar material, culture-specific units of native and foreign languages; formedness of monological and dialogical skills on definite topics; sociocultural material acquisition. The key parameters of operational criterion are: ability to use culture-specific units and units of non-verbal communication, which comply with communicative situation; skillful use of lexical units and grammatical structures pursuant to context; ability to organize dialogue / monologue in alignment with the norms of everyday, learning, professional activities. In terms of behavioral and activity criterion such parameters are considered as: restraint in judgements; ability to control one’s behavior; ability to analyze divergent positions before making a final decision. In conformance with the criteria and parameters determined there are four levels of cross-cultural competence specified: elementary, intermediate, upper-intermediate, advanced.

The Diagnostic Challenge of the Late-Onset Frontal Lobe Syndrome: Clinical Predictors for Primary Psychiatric Disorders Versus Behavioral Variant Frontotemporal Dementia.

Primary psychiatric disorders (PsD) can present with symptomatology identical to that of behavioral variant frontotemporal dementia (bvFTD). To date, clinical guidelines do not provide a solution for this diagnostic challenge. The aim of our study was to prospectively determine which demographic, clinical, neuropsychological, neuroimaging, and cerebrospinal fluid biomarkers are important in distinguishing PsD from bvFTD. Patients with late-onset behavioral disturbances (aged 45-75 years, 73% male) were included based on their scores on the Frontal Behavioral Inventory and the Stereotypy Rating Inventory and followed for 2 years from April 2011 to June 2015. Odds ratios (ORs) were calculated with backward stepwise logistic regression analyses to investigate the association between baseline clinical and demographic variables and the 2-year follow-up diagnosis of PsD (n = 46) (DSM-IV) versus probable/definite bvFTD (n = 27) (International Behavioral Variant FTD Criteria Consortium criteria). We separately measured the association between additional investigations and the 2-year follow-up diagnosis. Finally, we combined the selected variables to measure the predictive value of both clinical and additional investigations in a single model. Male gender (OR = 5.9; 95% CI, 1.3-26.0), less stereotypy (OR = 0.08; 95% CI, 0.02-0.34), and more depressive symptoms (OR = 1.13; 95% CI, 1.04-1.24) explained 49% of the variance predicting PsD versus bvFTD (χ²₃ = 29.4, P < .001) and correctly classified 82.1% of the cases. Neuroimaging (OR = 0.02; 95% CI, 0.002-0.123) explained 55% of the variance (χ²₁ = 37.5, P < .001) and, in combination with clinical variables, 66.1% of the variance (χ²₃ = 44.06, P < .001). The present study demonstrated that PsD can be distinguished from probable/definite bvFTD with a thorough clinical evaluation by a psychiatrist and neurologist along with use of validated questionnaires for depression and stereotypy; these measures are even more effective in combination with neuroimaging.

Adjunctive treatment with brexpiprazole and escitalopram reduces behavioral stress responses and increase hypothalamic NPY immunoreactivity in a rat model of PTSD-like symptoms

The study explored effects of brexpiprazole (partial D2/5-HT1A agonist, 5-HT2A and α1B/2C-adrenoceptor antagonist) in rats exposed to predator scent stress (PSS), a proposed model of PTSD-like phenotype. Brexpiprazole (3.0mg/kg, PO), escitalopram (5.0mg/kg, IP) and their combination were administered twice daily for 14 days, starting 14 days after exposure to PSS or sham-PSS, shortly after a situational stress reminder. One day after last treatment behavioral responsivity was assessed. Brexpiprazole+escitalopram-treated rats spent more time in open arms, entered open arms more often and exhibited a lower anxiety index in the elevated plus maze than vehicle-treated, PSS-exposed rats. Adjunct brexpiprazole+escitalopram treatment reduced startle amplitude, compared with vehicle-treated, PSS-exposed rats. Treatment with either drug alone did not attenuate anxiety-like behaviors following PSS exposure. Use of cut-off behavioral criteria confirmed that adjunct treatment shifted prevalence of PSS-exposed rats from extreme towards minimal behavioral responders. One day following behavioral tests, brains were prepared for immunohistochemical analysis of number of BDNF-positive cells and of NPY-positive cells/fibers. PSS exposure decreased BDNF levels in hippocampus, but this was not affected by drug treatments. PSS exposure decreased number of NPY positive cells/fibers in paraventricular and arcuate nuclei of hypothalamus. Adjunct treatment with brexpiprazole+escitalopram increased NPY in PSS- and sham-exposed rats. Treatment with brexpiprazole alone had no effects, while treatment with escitalopram alone increased NPY in the arcuate nucleus of PSS-exposed rats. In conclusion, treatment with brexpiprazole+escitalopram may be an effective intervention for the attenuation of PTSD-like stress responses, which in part may be mediated by activating NPY function.

Reforming the taxonomy in disorders of consciousness.

This article examines the serious shortcomings that characterize the current taxonomy of postcomatose disorders of consciousness (DoC), and it provides guidelines for how an improved DoC taxonomy might be developed. In particular, it is argued that behavioral criteria for the application of DoC categories should be supplemented with brain-based criteria (eg, information derived from electroencephalography and functional magnetic resonance imaging), and that the categorical framework that currently characterizes DoC should be replaced by a multidimensional framework that better captures the performance of patients across a range of cognitive and behavioural tasks.

A study on the predictive validity of conditional reasoning test for aggression

The purpose of this study was to examine the channeling model to investigate the interaction effect of implicit measure (Conditional Reasoning Test for Aggression: CRT-A) and self-reported measure of aggression to predict helping behavior. Expatriates who were dispatched to China or India (N=101) participated in this study. To reduce the common method bias, their host country co-workers (N=320) evaluated the expatriates’ helping behavior as a behavioral criterion. The results showed that there was a significance difference in helping behavior among the expatriates who had high CRT-A scores. Specifically, latent aggressive individuals who consciously perceived themselves as being non-aggressive but implicitly rationalized their aggressive behavior were less likely to show helping behavior. The academic implications of the current study, along with suggestions for the future research, were discussed.

On the risk of dependence on gabapentinoids

In the last ten years, the prescriptions of the gabapentinoids gabapentin and pregabalin increased largely also in Germany. Since several national and international pharmacovigilance-databases have warned for abuse liabilities and overdose fatalities in association with both gabapentinoids, which moreover, became to be sold on internet and black-markets, their addictive power has been subject to an ongoing clinical debate. As pre- and post-approval clinical trials did not reveal significant signs of dependence on gabapentin or pregabalin, we systematically searched in PubMed and Scopus for clinical studies and case reports being associated with abuse of and dependence on these drugs. We found 14 clinical-epidemiologic studies and 38 case reports/series. These were evaluated for i) fulfilled dependence criteria according to ICD-10, ii) non-medical self-administration and their duration, iii) relapses, iv) social sequels, and v) cases seeking treatment for misusing gabapentin or pregabalin. Mostly, the cases of abuse of and dependence on gabapentinoids appeared to be associated with other substance dependencies, primarily opiate dependence and polyvalent drug use. Drug users preferred pregabalin citing a faster and stronger euphoria ("liking") than achievable with oral gabapentin. Both gabapentinoids were anxiolytic in therapeutic doses, stimulating in lower and sedating along with increasing doses. Fatalities have been described mainly in the population of opiate dependents and polyvalent drug users, predominantly together with excessive pregabalin overdosing. It is debated whether the gabapentinoids were indeed the main cause of death in these cases or whether gabapentin and pregabalin had been only bystanders. Tolerance and withdrawal symptoms (physical dependence) of gabapentinoids appeared to be common in medical and non-medical use of gabapentinoids. There were only 4 persons who had fulfilled behavioral dependence criteria of gabapentinoids (all had used pregabalin) and had no association with other substance use disorders (apart from nicotine). Regarding the transitions from prescription to non-medical self-administration, the frequency and duration of self-administrations as well as the number of reported relapses, pregabalin appeared also to be more addictive than gabapentin. However, all these events were reported rather infrequently compared with traditional substances of abuse. We did not find a case with social sequalea due to the use of gabapentinoids or a person who sought treatment for his gabapentin or pregabalin use. Therefore, the gabapentinoids were assumed to possess a lower "wanting" in consideration of Berridge's and Robinsons's incentive-sensitization theory of addiction. Also, anti-adverse selection of gabapentinoids is discussed to be present in the population of opioid and multi-drug users. Based upon all these results and assumptions, we have estimated the relative risk of dependence on gabapentinoids by using an algorithm which was previously developed by Griffith and Johnson for evaluation of the abuse liabilities of sedatives. Overall, the risk of harm and dependence on gabapentinoids appeared to be lower than that of other sedatives (and stimulants). In addition, pregabalin appeared to be somewhat riskier than gabapentin. We think that in patients with current or past substance use disorders, the treatment with gabapentinoids should be avoided or if indispensable, these drugs should be administered exclusively over a limited time span with caution by using a therapeutic and prescription monitoring.

Analysis on early clinical features of behavioral variant frontotemporal dementia

Background Although the early behavioral symptoms of behavioral variant frontotemporal dementia (bvFTD) are prominent, early diagnosis for bvFTD is difficult due to confusion with other mental disorders, and lack of sensitivity and specificity of diagnostic criteria, etc. In this paper, we summarized the important reviews in recent years and analyzed the clinical characteristics of bvFTD patients to improve the detection of early symptoms in bvFTD. Methods Twenty-three possible or probable bvFTD patients were diagnosed according to International Behavioral Variant Frontotemporal Dementia Criteria Consortium (FTDC). Self-designed questionnaires designed by Shanghai Mental Health Center were used to collect sociodemographic data and general information of patients. Their clinical characteristics were summarized, including abnormal behaviors, cognitive impairment, psychotic symptoms and other symptoms. Mini-Mental State Examination (MMSE), Activities of Daily Living (ADL) and Clinical Dementia Rating Scale (CDR) were used to make neuropsychological tests and compare with similar overseas studies (control group, N = 66). Results Eleven male patients and 12 female patients were included in our study. Compared with control group, the average age of onset [(50.83 ± 11.55) years vs. (57.00 ± 10.00) years; t = 3.863, P = 0.000] and average age of diagnosis [(53.22 ± 11.55) years vs. (61.00 ± 9.00) years; t = 13.423, P = 0.000] of bvFTD patients were smaller. The study showed that bvFTD patients had more apathy or indolence [95.65% (22/23) vs. 65.15% (43/66); χ 2 = 8.057, P = 0.005], loss of sympathy or empathy [95.65% (22/23) vs. 33.33% (22/66); χ 2 = 26.499, P = 0.000], while patients in control group showed more derepression behavior [98.48% (65/66) vs. 52.17% (12/23); χ 2 = 27.514, P = 0.000] and continuous, stiff, obsessive and/or ritualized behavior [95.45% (63/66) vs. 30.43% (7/23); adjusted χ 2 = 39.159, P = 0.000]. For cognitive impairment, bvFTD patients presented apraxia [69.56% (16/23) vs. 22.73% (15/66); χ 2 = 16.484, P = 0.000] and executive dysfunction [82.61% (19/23) vs. 59.09% (39/66); χ 2 = 4.156, P = 0.041]. In psychotic symptoms, patients in control group showed hallucination and delusion [33.33% (22/66) vs. 4.35% (1/23); χ 2 = 7.477, P = 0.006]. Conclusions While the behavioral symptoms of bvFTD patients are varied, memory disorder can be one of the primal symptoms. Compared with similar foreign studies, the different composition of behavior symptoms of our bvFTD patients may be caused by cultural differences among evaluators in the understanding of some clinical symptoms in patients.

A Study on the predictive validity of Conditional Reasoning Test for Aggression: Interaction effect with self-reported measures

Artificial neural network for ecological-economic zoning as a tool for spatial planning

Abstract: The objective of this work was to analyze social and environmental information through an artificial neural network-self-organizing map (ANN-SOM), in order to provide subsidy to ecological-economic zoning (EEZ) as a tool to reduce the subjectivity of the process. The study area comprises 16 municipalities in the northeast of the state of Pará, Brazil, representative of the agricultural development in the state. Data processing involved three steps: preparation of the data in a geographic information system (GIS) environment; mathematical processing (ANN-SOM) of the data; and visualization and interpretation of the processing results, allowing the spatial planning of northeastern Pará. The results comprised 13 classes, regrouped according to behavioral similarity criteria into four categories, which represent the main areas of sustainability proposed for the state of Pará, according to existing EEZ. The proposed methodology allows individualizing areas in the region that EEZ had not defined, mainly due to the greater possibility of combining and integrating a large number of physical, social, and economic variables through the SOM.

Clinical characteristics of generalized anxiety disorder: older vs. young adults

Background: Generalized anxiety disorder (GAD) is one of the most common anxiety disorders in older people. Although GAD in older adults seems to differ in many aspects like clinical presentation, severity and treatment response, there is a paucity of comparative research.Aims: The aim of the study is to compare the clinical presentation of GAD between older and young adults.Methods: One hundred and two non-demented older patients (age ≥65) and 64 young patients (age <45) who were diagnosed with GAD according to the DSM-IV-TR criteria were included to the study. Socio-demographic Data Form, the Structured Clinical Interview for DSM Disorders-1 (SCID-1), the Questionnaire for the Suggested Behavioral Criteria of GAD for DSM-5, the Hamilton Depression Scale (HAM-D), the Generalized Anxiety Disorder Severity Scale (GADSS) and the Sheehan Disability Scale (SDS) were applied to both groups.Results and conclusions: Older GAD patients had more disturbances of sleep, less reassurance seeking behaviors, higher rates of depression and higher depression severity when compared to the young patients. Although older people seemed to have a lower severity of GAD, they had higher disability due to worries. Older patients worried more about their own health and family well-being, whereas young patients worried more about future and other’s health.

Multiple functional networks modeling for autism spectrum disorder diagnosis.

Despite countless studies on autism spectrum disorder (ASD), diagnosis relies on specific behavioral criteria and neuroimaging biomarkers for the disorder are still relatively scarce and irrelevant for diagnostic workup. Many researchers have focused on functional networks of brain activities using resting-state functional magnetic resonance imaging (rsfMRI) to diagnose brain diseases, including ASD. Although some existing methods are able to reveal the abnormalities in functional networks, they are either highly dependent on prior assumptions for modeling these networks or do not focus on latent functional connectivities (FCs) by considering discriminative relations among FCs in a nonlinear way. In this article, we propose a novel framework to model multiple networks of rsfMRI with data-driven approaches. Specifically, we construct large-scale functional networks with hierarchical clustering and find discriminative connectivity patterns between ASD and normal controls (NC). We then learn features and classifiers for each cluster through discriminative restricted Boltzmann machines (DRBMs). In the testing phase, each DRBM determines whether a test sample is ASD or NC, based on which we make a final decision with a majority voting strategy. We assess the diagnostic performance of the proposed method using public datasets and describe the effectiveness of our method by comparing it to competing methods. We also rigorously analyze FCs learned by DRBMs on each cluster and discover dominant FCs that play a major role in discriminating between ASD and NC.

Blood hormone profiles, physiological variables, and behavioral criteria in Corriedale ewes fed different TMR moisture levels during thermal–humidity exposure

In this study, blood hormone profiles, physiological variables, and behavioral criteria in Corriedale ewes fed total mixed ration (TMR) at different moisture levels during thermal–humidity exposure were evaluated. Nine non-pregnant Corriedale ewes (ave. BW = 41 ± 3.5 kg) were individually fed diets based on maintenance requirements in metabolic crates. Ewes were assigned to three treatment groups according to a 3 × 3 Latin Square design for 3 periods of 21 days duration each (9 ewes per treatment). Treatments were TMR (CP (crude protein) = 16.1, TDN (total digestible nutrients) = 69.1%) moisture levels at 40, 50, and 60%. No differences were found in blood hormone profiles including cortisol (μg/dL), immunoglobulin G (mg/dL), triiodothyronine (ng/mL), thyroxin (μg/dL), growth hormone (ng/mL), prolactin (ng/mL), insulin (μU/mL), insulin-like growth factor 1 (ng/mL), aldostrone (ng/dL), antidiuretic hormone (pg/mL), and creatinine (mg/dL) among all treatment groups (p > 0.05). Measurements of physiological variables indicated that heart rate (number of beats/min) in the afternoon was higher in 50 and 60% TMR group than in the 40% group (p < 0.05). No differences were observed in respiratory rate (number/min), panting score, and fecal score among the groups (p > 0.05). The behavior criteria including urine excretion frequency (number/d), fecal excretion frequency (number/d), standing frequency (number/d), resting frequency (number/d), standing duration (min/d), and resting duration (min/d) showed no differences among the treatment groups (p > 0.05). Conclusions drawn indicate the minor impacts of TMR moisture levels up to 60% on behavioral criterions of Corriedale ewes during thermal–humidity exposure, but help smooth down the intensified heat stress conditions over physiological variables and endocrine system.

Exploring relationship variables and Information and Communication Technologies use in industrial segmentation

PurposeIn tourism, the adoption of Information and Communication Technologies (hereinafter ICT) and variables concerning firms’ links with suppliers have been recognized as key determinants to improve companies’ competitiveness. From the perspective of efficient management of company resources, segmentation has become a key tool and is particularly significant and current in the business-to-business context. The purpose of this paper is to study the segmentation of firms in the tourist industry according to perceived ICT use and relationship value and benefits. In addition, from the management approach, the authors seek to describe the segments that enable the development of differentiated strategies aimed at consolidating relationship benefits in the long term.Design/methodology/approachUsing a sample of 310 travel agencies who evaluated the relationship with their main supplier, the authors attempt to examine the utility of these variables as segmentation criteria for identifying heterogeneous groups.FindingsThe estimation of a finite mixture model suggests that these bases are able to discriminate firms into four latent segments with different levels of ICT use and relationship variables.Research limitations/implicationsThis research contributes to the understanding of the role that ICT and relationship variables have in the segmentation processes of tourism companies. Literature on segmentation in the business-to-business (B2B) context is limited and it is hard to find studies which apply latent methodology using behavioral criteria related to the use of ICT and relationship variables.Practical implicationsSegmentation of the tourism organizational market based on valuations of supplier relations and ICT use can help suppliers to design or adapt differentiation marketing strategies. Since agencies place the most value on confidence and value, tourism service suppliers should focus their efforts on improving the elements of service provision that increase perceived trust/confidence and value (i.e. growing the number of contacts, proximity to customers or sincerity, etc.). If agencies feel they can rely more on their providers, they will value their relationship more positively thereby favoring its long-term continuity.Originality/valueThe novelty in this work lies in the application of latent segmentation methodology and the simultaneous use of bases associated with ICT and relationship variables in B2B tourism.

The cultural aspect: How to measure and interpret epidemiological data on alcohol-use disorders across cultures.

Aims:To examine the cultural impact on the diagnosis of alcohol-use disorders using European countries as examples.Design:Narrative review.Results:There are strong cultural norms guiding heavy drinking occasions and loss of control. These norms not only indicate what drinking behaviour is acceptable, but also whether certain behaviours can be reported or not. As modern diagnostic systems are based on lists of mostly behavioural criteria, where alcohol-use disorders are defined by a positive answer on at least one, two or three of these criteria, culture will inevitably co-determine how many people will get a diagnosis. This explains the multifold differences in incidence and prevalence of alcohol-use disorders, even between countries where the average drinking levels are similar. Thus, the incidence and prevalence of alcohol-use disorders as assessed by surveys or rigorous application of standardised instruments must be judged as measuring social norms as well as the intended mental disorder.Conclusions:Current practice to measure alcohol-use disorders based on a list of culture-specific diagnostic criteria results in incomparability in the incidence, prevalence or disease burden between countries. For epidemiological purposes, a more grounded definition of diagnostic criteria seems necessary, which could probably be given by using heavy drinking over time.

Spatial organization and social relations in a reintroduced population of Endangered Iberian lynx Lynx pardinus

AbstractIn 2015 10 Iberian lynxes Lynx pardinus were released in south-eastern Portugal, within the framework of a Spanish–Portuguese reintroduction project. We examined each individual's use of space and social interactions during the first year after their release. Lynxes were selected for reintroduction according to behavioural, genetic and health criteria and fitted with collars with VHF and global positioning systems. Both males and females went through an exploratory phase that lasted 65–105 days. The lynxes did not exhibit any movement directionality from the release site during the exploratory period. During August–December 2015 a stable nucleus comprising seven individuals (four males, three females) was established south-west of the release enclosure. Although the males had a slightly larger mean home range (11.18 ± SE 1.36 km2) than females (9.87 ± SE 8.71 km2), the difference was not significant. The knowledge obtained during the first year of the lynx reintroduction project in Portugal is critical to support the future of this reintroduction strategy. Our results suggest that once the soft release technique is no longer possible because of logistical constraints on the construction of more enclosures, new individuals should be released in unoccupied areas surrounded by occupied territories. This will promote strong social ties to the resident population and prevent lynx dispersal.

Evaluating the predictive validity of personality trait judgments using a naturalistic behavioral criterion: A preliminary test of the self-other knowledge asymmetry model

We tracked 87 participants over two days using the Electronically Activated Recorder (EAR). Coded variables included expressions of mood, amount of talking in various situations (e.g., with one other person, with a friend, etc.), locations, and behavioral markers of the Big Five. Collection of self-, informant-, and stranger-ratings on markers of the Big Five allowed for a unique test of the Self-Other Knowledge Asymmetry (SOKA) model. Although effect sizes were modest, there was evidence for the validity of both self- and informant-ratings across most trait dimensions. Stranger-ratings showed evidence of validity in the domain of Extraversion. Predictions derived from the SOKA model were partially supported, though more research with larger samples is needed to provide stronger tests of SOKA.

Diagnóstico precoz del VIH en atención primaria en España. Resultados de una prueba piloto de cribado dirigido basado en condiciones indicadoras, criterios conductuales y de origen

ObjectivesTo estimate the prevalence of HIV infection in patients diagnosed with an indicator condition (IC) for HIV and/or risk behavior for their acquisition and/or coming from high prevalence countries. To determine the acceptability and feasibility of offering HIV testing based on IC and behavioral and origin criteria in Primary Care (PC). DesignCross-sectional study in a convenience sample. LocationSix PC centers in Spain. ParticipantsThe inclusion criteria were: patients between 16 and 65years old who presented at least one of the proposed ICs and/or at least one of the proposed behavioral and/or origin criteria. A total of 388 patients participated. InterventionHIV serology was offered to all patients who met the inclusion criteria. Main measurementsDescription of IC frequency, behavioral and origin criteria. Prevalence of HIV infection. Level of acceptability and feasibility of the HIV screening based on IC and behavioral and origin criteria. ResultsA total of 174 patients had an IC (44.84%). The most common behavioral criterion was: having unprotected sex at some time in life with people who did not know their HIV status (298; 76.8%). Four HIV+ patients (1.03%) were diagnosed. All had an IC and were men who had sex with men. The level of acceptability in PC was high. ConclusionsOffering HIV testing to patients with IC and behavioral criteria is feasible and effective in PC.
