Pathological gambling in adolescence: A narrative review

Pathological gambling is an emerging and increasing phenomenon in Western counties. This work is aimed at reviewing the existing literature on this topic, paying special attention to its development, course and outcome in adolescence. We will explore epidemiological data, the instruments for the diagnostic and clinical assessment, the course and the outcome of the disorder, the comorbidity with other psychiatric syndromes and disorders. The main risk factors will be described at individual, social and community level. We provide an overview of the available pharmacological and psychological treatments and we report a clinical vignette in order to describe the psychological and psychopathological features of pathological gambling in adolescence

External Validation Of Equations To Estimate Resting Energy Expenditure In 14952 Adults With Overweight And Obesity And 1948 Adults With Normal Weight From Italy

Background & aims: We cross-validated 28 equations to estimate resting energy expenditure (REE) in a very large sample of adults with overweight or obesity. Methods: 14952 Caucasian men and women with overweight or obesity and 1498 with normal weight were studied. REE was measured using indirect calorimetry and estimated using two meta-regression equations and 26 other equations. The correct classification fraction (CCF) was defined as the fraction of subjects whose estimated REE was within 10% of measured REE. Results: The highest CCF was 79%, 80%, 72%, 64%, and 63% in subjects with normal weight, overweight, class 1 obesity, class 2 obesity, and class 3 obesity, respectively. The Henry weight and height and Mifflin equations performed equally well with CCFs of 77% vs. 77% for subjects with normal weight, 80% vs. 80% for those with overweight, 72% vs. 72% for those with class 1 obesity, 64% vs. 63% for those with class 2 obesity, and 61% vs. 60% for those with class 3 obesity. The Sabounchi meta-regression equations offered an improvement over the above equations only for class 3 obesity (63%). Conclusions: The accuracy of REE equations decreases with increasing values of body mass index. The Henry weight & height and Mifflin equations are similarly accurate and the Sabounchi equations offer an improvement only in subjects with class 3 obesity

Views of Schizophrenia Among Future Healthcare Professionals: Differences in Relation to Diagnostic Labelling, Causal Explanations, and Type of Academic Degree Program

Objective: Stereotyped beliefs about schizophrenia are well-established in the society and relatively common among healthcare professionals and students. The aim of this study was to investigate the opinions about the causes, treatment, and outcome of schizophrenia among healthcare students. Method: Undergraduate nursing and psychology students completed selected items of the Opinion on Mental Illness Questionnaire after reading a clinical vignette of undiagnosed schizophrenia. Results: Students who labelled the description as schizophrenia were more pessimistic regarding full recovery from the disorder. Those who acknowledged greater relevance to biogenetic risk factors were more convinced of the efficacy of medications. Respondents’ opinions on the efficacy of psychological interventions were more positive among psychology students than among nursing students. Conclusions: The study confirmed the associations of schizophrenia labelling with prognostic pessimism and beliefs about the efficacy of pharmacological treatment among future healthcare professionals. Students’ opinions were less influenced by differences between academic degree programs. Information about current recovery rate and comprehensive care for schizophrenia may support future healthcare professionals in the relationship and the clinical management of PWS

Body mass reduction markedly improves muscle performance and body composition in obese females aged 61-75 years: comparison between the effects exerted by energy-restricted diet plus moderate aerobic-strength training alone or associated with rGH or nandrolone undecanoate

OBJECTIVE: To investigate the effectiveness of a body mass reduction programme entailing diet caloric restriction and moderate physical activity with or without supplementary treatment with recombinant (r) GH or steroids to improve body composition and muscle performance in severely obese women aged 61-75 years. METHODS: Twenty women were randomly assigned to one of three groups: body mass reduction alone; body mass reduction plus rGH; body mass reduction plus nandrolone undecanoate. Body composition, isotonic muscle strength and anaerobic power output during jumping were determined before and after the 3-week period. RESULTS: Whatever the experimental group considered, body mass (P<0.01), body mass index (P<0.05) and fat mass (P<0.05) decreased significantly, whereas muscle strength and power increased significantly (P<0.05) after the intervention. CONCLUSION: Small body mass reductions after 3 weeks of energy-restricted diet combined with moderate aerobic and strength exercise are associated with significant improvements in upper and lower limb muscle strength and power and reduction of fat mass in severely obese women aged 61-75 years. Although the association of rGH or nandrolone undecanoate does not appear to exert additional effects on body composition and muscle performance attained by body mass reduction alone, further additional studies with larger study groups, different dosages and more prolonged periods are required for definitive conclusions to be drawn

Perceived public stigma towards schizophrenia among healthcare students: The relationship with diagnostic labelling and contact with people with schizophrenia

Objectives This study aimed at investigating the relationship between perceived public stigma towards people with schizophrenia (PWS) and their family members in a large sample of medical and psychology students. We hypothesised that: a) schizophrenia labelling would be related to greater perceived public stigma; b) contact with PWS would be related with lower perceived stigma; c) perceived public stigma would be similar between medical and psychology students and would be higher among students attending the clinical stage compared to their pre-clinical colleagues. Methods Participants were 592 students attending either the pre-clinical or clinical stage of coursework in Medicine and Psychology, at the University of Palermo (Italy) (Tab. I). Study measures included a short socio-demographic questionnaire, the Devaluation of Consumers Scale (DCS), and the Devaluation Consumers Families Scale (DCFS). Results Students who identified schizophrenia in an unlabelled clinical description expressed greater perceived public stigma towards PWS (t = -2.895, p = 0.004) and their family members (t = -2.389, p = 0.017). A trend-level association was found between previous contact with PWS and lower perceived public stigma (t = 1.903, p = 0.058), which became significant for those students who had a more extensive contact (Mann-Whitney z = 2.063, p = 0.039). Compared to medical students, psychology students perceived greater public stigma towards PWS. No difference was observed between students at different stages of their academic coursework (Tab. II). In a multivariate linear regression model, schizophrenia labelling and degree course predicted perceived public stigma towards severe mental disorders. Conclusions This study replicated previous findings on the relationship between public stigma towards PWS, schizophrenia labelling, and contact with PWS. Perception of public stigma was similar among pre-clinical and clinical students and greater among psychology students. The findings suggest the importance of promoting a critical awareness of negative stereotypes towards schizophrenia among healthcare students, since the beginning of their coursework. In addition to correct information about schizophrenia, anti-stigma intervention should include contact with PWS who live in the community

Modern Acinetobacter baumannii clinical isolates replicate inside spacious vacuoles and egress from macrophages

Multidrug-resistant Acinetobacter baumannii infections are increasing at alarming rates. Therefore, novel antibiotic-sparing treatments to combat these A. baumannii infections are urgently needed. The development of these interventions would benefit from a better understanding of this bacterium\u27s pathobiology, which remains poorly understood. A. baumannii is regarded as an extracellular opportunistic pathogen. However, research on Acinetobacter has largely focused on common lab strains, such as ATCC 19606, that have been isolated several decades ago. These strains exhibit reduced virulence when compared to recently isolated clinical strains. In this work, we demonstrate that, unlike ATCC 19606, several modern A. baumannii clinical isolates, including the recent clinical urinary isolate UPAB1, persist and replicate inside macrophages within spacious vacuoles. We show that intracellular replication of UPAB1 is dependent on a functional type I secretion system (T1SS) and pAB5, a large conjugative plasmid that controls the expression of several chromosomally-encoded genes. Finally, we show that UPAB1 escapes from the infected macrophages by a lytic process. To our knowledge, this is the first report of intracellular growth and replication of A. baumannii. We suggest that intracellular replication within macrophages may contribute to evasion of the immune response, dissemination, and antibiotic tolerance of A. baumannii

Anticipatory and consummatory effects of (hedonic) chocolate intake are associated with increased circulating levels of the orexigenic peptide ghrelin and endocannabinoids in obese adults

BACKGROUND: Hedonic hunger refers to consumption of food just for pleasure and not to maintain energy homeostasis. Recently, consumption of food for pleasure was reported to be associated with increased circulating levels of both the orexigenic peptide ghrelin and the endocannabinoid 2-arachidonoyl-glycerol (2-AG) in normal-weight subjects. To date, the effects of hedonic hunger, and in particular of chocolate craving, on these mediators in obese subjects are still unknown. METHODS: To explore the role of some gastrointestinal orexigenic and anorexigenic peptides and endocannabinoids (and some related congeners) in chocolate consumption, we measured changes in circulating levels of ghrelin, glucagon-like peptide 1 (GLP-1), peptide YY (PYY), anandamide (AEA), 2-AG, palmitoylethanolamide (PEA), and oleoylethanolamide (OEA) in 10 satiated severely obese subjects after consumption of chocolate and, on a separate day, of a non-palatable isocaloric food with the same bromatologic composition. Evaluation of hunger and satiety was also performed by visual analogic scale. RESULTS: The anticipatory phase and the consumption of food for pleasure were associated with increased circulating levels of ghrelin, AEA, 2-AG, and OEA. In contrast, the levels of GLP-1, PYY, and PEA did not differ before and after the exposure/ingestion of either chocolate or non-palatable foods. Hunger and satiety were higher and lower, respectively, in the hedonic session than in the non-palatable one. CONCLUSIONS: When motivation to eat is generated by exposure to, and consumption of, chocolate a peripheral activation of specific endogenous rewarding chemical signals, including ghrelin, AEA, and 2-AG, is observed in obese subjects. Although preliminary, these findings predict the effectiveness of ghrelin and endocannabinoid antagonists in the treatment of obesity

Direct evidence that late Neanderthal occupation precedes a technological shift in southwestern Italy

Objectives During the middle-to-upper Paleolithic transition (50,000 and 40,000 years ago), interaction between Neanderthals and Homo sapiens varied across Europe. In southern Italy, the association between Homo sapiens fossils and non-Mousterian material culture, as well as the mode and tempo of Neanderthal demise, are still vividly debated. In this research, we focus on the study of two human teeth by using 3D geometric morphometric approaches for a reliable taxonomical attribution as well as obtaining new radiometric dates on the archeological sequence. Material and Methods This work presents two lower deciduous molars uncovered at Roccia San Sebastiano (Mondragone-Caserta, Italy), stratigraphically associated with Mousterian (RSS1) and Uluzzian (RSS2) artifacts. To obtain a probabilistic attribution of the two RSS teeth to each reference taxa group composed of Neanderthals and Homo sapiens, we performed and compared the performance of three supervised learning algorithms (flexible discriminant analysis, multiadaptive regression splines, and random forest) on both crown and cervical outlines obtained by virtual morphometric methods. Results We show that RSS1, whose Mousterian context appears more recent than 44,800-44,230 cal BP, can be attributed to a Neanderthal, while RSS2, found in an Uluzzian context that we dated to 42,640-42,380 cal BP, is attributed to Homo sapiens. Discussion This site yields the most recent direct evidence for a Neanderthal presence in southern Italy and confirms a later shift to upper Paleolithic technology in southwestern Italy compared to the earliest Uluzzian evidence at Grotta del Cavallo (Puglia, Italy)
