Higher plasma levels of thymosin-α1 are associated with a lower waning of humoral response after COVID-19 vaccination: an eight months follow-up study in a nursing home.

BACKGROUND: Older people achieve lower levels of antibody titers than younger populations after Covid-19 vaccination and show a marked waning humoral immunity over time, likely due to the senescence of the immune system. Nevertheless, age-related predictive factors of the waning humoral immune response to the vaccine have been scarcely explored. In a cohort of residents and healthcare workers from a nursing home that had received two doses of the BNT162b2 vaccine, we measured specific anti-S antibodies one (T1), four (T4), and eight (T8) months after receiving the second dose. Thymic-related functional markers, including thymic output, relative telomere length, and plasma thymosin-α1 levels, as well as immune cellular subsets, and biochemical and inflammatory biomarkers, were determined at T1, and tested for their associations with the magnitude of the vaccine response (T1) and the durability of such response both, at the short- (T1-T4) and the long-term (T1-T8). We aimed to identify age-related factors potentially associated with the magnitude and persistence of specific anti-S immunoglobulin G (IgG)-antibodies after COVID-19 vaccination in older people. RESULTS: Participants (100% men, n = 98), were subdivided into three groups: young (< 50 years-old), middle-age (50-65 years-old), and older (≥65 years-old). Older participants achieved lower antibody titers at T1 and experienced higher decreases in both the short- and long-term. In the entire cohort, while the magnitude of the initial response was mainly associated with the levels of homocysteine [ß (95% CI); - 0.155 (- 0.241 to - 0.068); p = 0.001], the durability of such response at both, the short-term and the long-term were predicted by the levels of thymosin-α1 [- 0.168 (- 0.305 to - 0.031); p = 0.017, and - 0.123 (- 0.212 to - 0.034); p = 0.008, respectively]. CONCLUSIONS: Higher plasma levels of thymosin-α1 were associated with a lower waning of anti-S IgG antibodies along the time. Our results suggest that plasma levels of thymosin-α1 could be used as a biomarker for predicting the durability of the responses after COVID-19 vaccination, possibly allowing to personalize the administration of vaccine boosters.

Risk factors for neurodegeneration in idiopathic rapid eye movement sleep behavior disorder: a multicenter study.

OBJECTIVE: To assess whether risk factors for Parkinson disease and dementia with Lewy bodies increase rate of defined neurodegenerative disease in idiopathic rapid eye movement (REM) sleep behavior disorder (RBD). METHODS: Twelve centers administered a detailed questionnaire assessing risk factors for neurodegenerative synucleinopathy to patients with idiopathic RBD. Variables included demographics, lifestyle factors, pesticide exposures, occupation, comorbid conditions, medication use, family history, and autonomic/motor symptoms. After 4 years of follow-up, patients were assessed for dementia or parkinsonism. Disease risk was assessed with Kaplan-Meier analysis, and epidemiologic variables were compared between convertors and those still idiopathic using logistic regression. RESULTS: Of 305 patients, follow-up information was available for 279, of whom 93 (33.3%) developed defined neurodegenerative disease. Disease risk was 25% at 3 years and 41% after 5 years. Patients who converted were older (difference = 4.5 years, p < 0.001), with similar sex distribution. Neither caffeine, smoking, nor alcohol exposure predicted conversion. Although occupation was similar between groups, those who converted had a lower likelihood of pesticide exposure (occupational insecticide = 2.3% vs 9.0%). Convertors were more likely to report family history of dementia (odds ratio [OR] = 2.09), without significant differences in Parkinson disease or sleep disorders. Medication exposures and medical history were similar between groups. Autonomic and motor symptoms were more common among those who converted. Risk factors for primary dementia and parkinsonism were generally similar, except for a notably higher clonazepam use in dementia convertors (OR = 2.6). INTERPRETATION: Patients with idiopathic RBD are at very high risk of neurodegenerative synucleinopathy. Risk factor profiles between convertors and nonconvertors have both important commonalities and differences.

Physiological and brain activity after a combined cognitive behavioral treatment plus video game therapy for emotional regulation in bulimia nervosa: a case report.

BACKGROUND: PlayMancer is a video game designed to increase emotional regulation and reduce general impulsive behaviors, by training to decrease arousal and improve decision-making and planning. We have previously demonstrated the usefulness of PlayMancer in reducing impulsivity and improving emotional regulation in bulimia nervosa (BN) patients. However, whether these improvements are actually translated into brain changes remains unclear. OBJECTIVE: The aim of this case study was to report on a 28-year-old Spanish woman with BN, and to examine changes in physiological variables and brain activity after a combined treatment of video game therapy (VGT) and cognitive behavioral therapy (CBT). METHODS: Ten VGT sessions were carried out on a weekly basis. Anxiety, physiological, and impulsivity measurements were recorded. The patient was scanned in a 1.5-T magnetic resonance scanner, prior to and after the 10-week VGT/CBT combined treatment, using two paradigms: (1) an emotional face-matching task, and (2) a multi-source interference task (MSIT). RESULTS: Upon completing the treatment, a decrease in average heart rate was observed. The functional magnetic resonance imaging (fMRI) results indicated a post-treatment reduction in reaction time along with high accuracy. The patient engaged areas typically active in healthy controls, although the cluster extension of the active areas decreased after the combined treatment. CONCLUSIONS: These results suggest a global improvement in emotional regulation and impulsivity control after the VGT therapy in BN, demonstrated by both physiological and neural changes. These promising results suggest that a combined treatment of CBT and VGT might lead to functional cerebral changes that ultimately translate into better cognitive and emotional performances.

[Executive summary of the recommendations on the evaluation and management of renal disease in human immunodeficiency virus-infected patients]. / Resumen ejecutivo del documento de consenso sobre el manejo de la patología renal en pacientes con infección por el virus de la inmunodeficiencia humana.

The aim of this article is to update the 2010 recommendations on the evaluation and management of renal disease in human immunodeficiency virus (HIV)-infected patients. Renal function should be monitored in all HIV-infected patients. The basic renal work-up should include measurements of serum creatinine, estimated glomerular filtration rate by CKD-EPI, urine protein-to-creatinine ratio, and urinary sediment. Tubular function tests should include determination of serum phosphate levels and urine dipstick for glycosuria. In the absence of abnormal values, renal screening should be performed annually. In patients treated with tenofovir, or with risk factors for chronic kidney disease (CKD), more frequent renal screening is recommended. In order to prevent disease progression, potentially nephrotoxic antiretroviral drugs are not recommended in patients with CKD or risk factors for CKD. The document provides indications for renal biopsy and advises on the optimal time for referral of a patient to the nephrologist. The indications for and evaluation and management of dialysis and renal transplantation are also addressed.

Changes in vessel density patterns assessed with OCTA in patients with diabetic macular edema treated with anti-VEGF therapy.

AIMS: To determine the presence of sectoral changes in vessel density (VD) patterns induced by vascular endothelial growth factor inhibitors (anti-VEGF) in patients with diabetic macular edema (DME) using optical coherence tomography angiography (OCTA). METHODS: Prospective, interventional study. A total of 43 patients (63 eyes) were initially enrolled in the study. We performed swept source (SS) OCT and sectorial OCTA measurement to determine parafoveal VD at baseline and after six months of anti-VEGF treatment. In the locations with statistically significant differences in VD between baseline and month 6, we performed univariate and multivariate analyses to determine which, if any, of the baseline variables were associated with the observed changes. RESULTS: A total of 34 patients (48 eyes) were included in the final analysis. Mean VD decreased from baseline to month 6 (from 45.2 (± 3.5) to 44.6 (± 3.2) % in the SCP and from 50 (± 3.3) to 49 (± 3.9) % in the DCP). The only significant changes in VD were observed in the nasal sector of the deep capillary plexus, with a decrease of 2.9% (p = 0.001). On univariate and multivariate analyses, the only variable significantly associated with changes in VD in the nasal sector after 6 months of treatment was baseline VD in the same sector. CONCLUSIONS: Anti-VEGF therapy has a small impact on VD values over time. These variations observed after treatment seems to be related to changes over areas of vascular anomalies and displaced vessels adjacent to cystic areas, with no significant changes over ischemic areas. No correlation was observed between this trend and other clinical baseline features.

Intralesional Vessel Diameter Measured by Optical Coherence Tomography Angiography Could Improve the Differential Diagnosis of Small Melanocytic Choroidal Lesions.

In this study, we aimed to identify the features of indeterminate choroidal melanocytic lesions visualized on optical coherence tomography angiography (OCTA) and to identify the predictors of growth. We retrospectively evaluated 86 patients with indeterminate lesions treated at our centre from 2016 to 2021. Clinical management involved active surveillance followed by brachytherapy if growth was detected. The lesions were classified into two groups according to whether they grew (small melanomas) or remained stable (choroidal nevi). Growth was detected in 19 (22.1%) lesions. All patients underwent OCTA at baseline. These images were compared to identify the possible predictors of growth. Significant between-group differences were observed in thickness (p = 0.00), greatest basal diameter (p = 0.00), number of risk factors (p = 0.00), symptoms (p = 0.001; relative risk [RR]: 4.3), orange pigment (p = 0.00; RR: 6.02), and ultrasonographic hollowness (Kappa sign); p = 0.000; RR: 5.3). The melanomas had significantly more vessels with a diameter ≥ 76.3 µm (p = 0.02; RR: 2.46). The time to growth in these lesions was significantly shorter (p = 0.05) than in lesions with smaller vessels. These findings show that vessel diameter quantified by OCTA can help differentiate between choroidal nevi and small melanomas, when considered together with clinical risk factors.

Pathological gambling in eating disorders: prevalence and clinical implications.

OBJECTIVE: Pathological gambling (PG) and eating disorders (ED) rarely co-occur. We explored the prevalence of lifetime PG in ED, compared severity of ED symptoms, personality traits, and psychopathological profiles across individuals with ED and PG (ED+PG) and without PG (ED-PG). Finally, we assessed the incremental predictive value of gender on the presentation of a comorbid PG. METHOD: A total sample of 1681 consecutively admitted ED patients (1576 females and 105 males), participated in the current study (25 ED+PG and 1656 ED-PG). All participants were diagnosed according to DSM-IV criteria. Assessment measures included the Symptom Checklist and the Temperament and Character Inventory-Revised, as well as other clinical and psychopathological indices. RESULTS: The observed lifetime prevalence of PG was 1.49%. ED subtype was associated with lifetime PG (p=.003), with PG being more frequent in binge eating disorder (5.7%). ED+PG was more prevalent in males than in females (16% vs. 1.26%, respectively). Additionally, ED+PG patients exhibited more impulsive behaviours, lower impulse regulation and higher novelty seeking. Best predictors of ED+PG were novelty seeking (OR 1.030, p=.035), sex (OR 3.295, p=.048) and BMI (OR 1.081, p=.005). CONCLUSIONS: Some personality traits (novelty seeking), being male and higher BMI are strongly related to the presence of lifetime PG in specific ED subtypes (namely binge eating disorder).

[Analysis of costs and cost-effectiveness of preferred GESIDA/National AIDS Plan regimens for initial antiretroviral therapy in human immunodeficiency virus infected adult patients in 2013]. / Análisis de costes y de coste/eficacia de las pautas preferentes de GESIDA/Plan Nacional sobre el Sida en 2013 para el tratamiento antirretroviral inicial en adultos infectados por el virus de la inmunodeficiencia humana.

INTRODUCTION: The GESIDA and National AIDS Plan panel of experts have proposed "preferred regimens" of antiretroviral treatment (ART) as initial therapy in HIV infected patients for 2013. The objective of this study is to evaluate the costs and effectiveness of initiating treatment with these "preferred regimens". METHODS: An economic assessment of costs and effectiveness (cost/effectiveness) was performed using decision tree analysis models. Effectiveness was defined as the probability of having viral load <50copies/mL at week48, in an intention-to-treat analysis. Cost of initiating treatment with an ART regime was defined as the costs of ART and its consequences (adverse effects, changes of ART regime and drug resistance analyses) during the first 48weeks. The perspective of the analysis is that of the National Health System was applied, only taking into account differential direct costs: ART (official prices), management of adverse effects, resistance studies, and determination of HLA B*5701. The setting is Spain and the costs are those of 2013. A sensitivity deterministic analysis was performed, constructing three scenarios for each regimen: baseline, most favourable, and most unfavourable cases. RESULTS: In the baseline case scenario, the cost of initiating treatment ranges from 6,747euros for TDF/FTC+NVP to 12,059euros for TDF/FTC+RAL. The effectiveness ranges between 0.66 for ABC/3TC+LPV/r and ABC/3TC+ATV/r, and 0.87 for TDF/FTC+RAL and ABC/3TC+RAL. Effectiveness, in terms of cost/effectiveness, varies between 8,396euros and 13,930euros per responder at 48weeks, for TDF/FTC/RPV and TDF/FTC+RAL, respectively. CONCLUSIONS: Taking ART at official prices, the most effective regimen was TDF/FTC/RPV, followed by the rest of non-nucleoside containing regimens. The sensitivity analysis confirms the robustness of these findings.

Video game therapy for emotional regulation and impulsivity control in a series of treated cases with bulimia nervosa.

Although standard psychological treatments have been successful in treating several core features in eating disorders (ED), other characteristics such as emotional regulation or impulsivity appear to be more resistant to change. There is a growing body of evidence to support the efficacy of cognitive remediation for cognitive and emotional difficulties in ED. Playmancer/ Islands is a video game (VG) designed to specifically treat mental disorders, characterized by problems in impulse control. The objective of the game is to increase self-control over emotions, decision making and behaviours. The aim of this study is to describe the results from a consecutive series of nine bulimia nervosa patients who were treated with the VG in addition to cognitive behaviour therapy (CBT). The outcomes included clinical and psychopathological questionnaires, and physiological measures were obtained during the VG. Emotional regulation improved, heart rate variability increased, and respiratory rate and impulsivity measures reduced after the treatment. These findings suggest that VG training may enhance treatment for ED.

Correlation between Topographic Vessel Density and Retinal Thickness Changes in Patients with Diabetic Macular Edema Treated with Anti-VEGF Therapy: Is It a Suitable OCTA Biomarker?

The objective of this study was to determine the correlation between topographic vessel density (VD) and retinal thickness (RT) reductions induced by vascular endothelial growth factor inhibitors (anti-VEGF) in patients with diabetic macular edema (DME) using optical coherence tomography angiography (OCTA). This was a prospective, interventional case series. VD and RT measurements were separately taken in four parafoveal subfields at baseline and after six months of treatment. This correlation was statistically assessed using Spearman's rho correlation coefficient after adjustment for multiple comparisons. The study included a total of 48 eyes in the final analysis. Mean VD decreased from baseline to month 6 (from 45.2 (±3.5) to 44.6% (±3.2) in the superficial capillary plexus and from 50 (±3.3) to 49% (±3.9) in the deep capillary plexus). Statistically significant reductions in RT were observed in all ETDRS sectors (p < 0.0001). No significant association was found between RT and VD, even when analyzing responders and non-responders separately. After six months of anti-VEGF treatment, no significant correlation was observed between the topographic VD and RT values. These findings suggest that reductions in VD values may not solely result from a reduction in microaneurysms, also being affected by the repositioning of displaced vessels due to edema and a reduction in their caliber. Therefore, VD changes may not be a suitable indirect OCTA biomarker of microaneurysm turnover and treatment response.

Cognitive-behavioral therapy for pathological gambling in Parkinson's disease: a pilot controlled study.

OBJECTIVES: The main objective of this study was to compare the clinical characteristics and differences in response to treatment of two groups of pathological gamblers: with comorbid Parkinson's disease (PG + PD) and without (PG - PD). METHODS: Clinical and psychopathological profiles and response to cognitive-behavioral treatment were assessed in 15 PG + PD and 45 PG - PD individuals consulting a specialized hospital Unit. RESULTS: Statistically significant differences were observed between the two groups on a series of clinical variables. PG + PD patients were older and presented later onset of problematic gambling behaviors, lower alcohol consumption and higher bingo playing than PG - PD patients. No significant differences were noted in psychopathology except for lower measures of hostility in the PG + PD group. No statistical differences were detected between groups in terms of response to treatment. CONCLUSION: These results may provide guidance for obtaining accurate diagnostic information in pathological gamblers by properly identifying patients with specific needs that may be targeted with treatment.

Does exposure and response prevention improve the results of group cognitive-behavioural therapy for male slot machine pathological gamblers?

INTRODUCTION: Cognitive-behavioural therapy (CBT) seems to offer effective treatment for pathological gambling (PG). However, it has not yet been established which techniques yield the best results, or whether exposure and response prevention (ERP) techniques are of additional use. OBJECTIVES: To evaluate clinical and socio-demographic characteristics of a PG sample at baseline, comparing cognitive-behavioural group intervention, with and without exposure, with response prevention (CBT + ERP vs. CBT), to compare the results of therapy and to assess pre-post changes in psychopathology between both groups. DESIGN: We applied a quasi-experimental design comprising intervention on the independent variable, but without random assignment. METHODS: The sample comprised 502 males with PG, consecutively admitted to a specialist unit, who received standardized outpatient CBT group therapy in 16 weekly sessions. Scores on the Symptom Checklist-Revised (SCL-90-R), the Temperament and Character Inventory-Revised (TCI-R), the South Oaks Gambling Screen (SOGS), and other clinical and psychopathological scales were recorded. RESULTS: Pre-post changes did not differ between groups, except for SCL paranoid ideation, being greater in the CBT therapy group. The risk of relapse during treatment was similar in the CBT + ERP and CBT patients. However, compliance with treatment was poorer in the CBT + ERP group, who presented higher drop-out rates during treatment. Drop-out during therapy was associated with shorter disorder duration and higher scores on the TCI-R novelty seeking scale. CONCLUSIONS: Although the two CBT programs elicited similar therapy responses, patients receiving CBT alone showed higher adherence to therapy and lower drop-out rates.

[Costs and cost-efficacy analysis of the preferred treatments by GESIDA/National Plan for AIDS for the initial antiretroviral therapy in adult human immunodeficiency virus (HIV) infected patients in 2012]. / Análisis de costes y de coste/eficacia de las pautas preferentes de GESIDA/Plan Nacional sobre el Sida en 2012 para el tratamiento antirretroviral inicial en adultos infectados por el virus de la inmunodeficiencia humana (VIH).

INTRODUCTION: The GESIDA and National AIDS Plan panel of experts propose «preferred regimens¼ of antiretroviral treatment (ART) as initial therapy in HIV infected patients for 2012. The objective of this study is to evaluate the costs and the efficiency of initiating treatment with these «preferred regimens¼. METHODS: Economic assessment of costs and efficiency (cost/efficacy) using decision tree analysis model. Efficacy was defined as the probability of having a viral load <50 copies/ml at week 48, in an intention-to-treat analysis. Cost of initiating treatment with an ART regime was defined as the costs of ART and all its consequences (adverse effects, changes of ART regime, and drug resistance analyses) during the first 48 weeks. The perspective of the analysis is that of the National Health System, considering only differential direct costs: ART (official prices), management of adverse effects, studies of resistance and determination of HLA B 5701. The setting is Spain and the costs are those of 2012. A sensitivity deterministic analysis was conducted, building three scenarios for each regime: baseline, most favourable, and most unfavourable cases. RESULTS: In the baseline case scenario, the cost of initiating treatment ranges from 6,895 euros for TDF/FTC+NVP to 12,067 euros for TDF/FTC+RAL. The efficacy ranges between 0.66 for ABC/3TC+LPV/r and 0.87 for TDF/FTC+RAL. Efficiency, in terms of cost/efficacy, varies between 9,387 and 13,823 euros per responder at 48 weeks, for TDF/FTC/EFV and TDF/FTC+RAL, respectively. In the most unfavourable scenario, the most efficient regime is TDF/FTC+NVP (9,742 per responder). CONCLUSION: Considering the official prices of ART, the most efficient regimens are TDF/FTC/EFV (baseline case and most favourable scenarios), and TDF/FTC+NVP (most unfavourable scenario).

Correlates of motivation to change in pathological gamblers completing cognitive-behavioral group therapy.

OBJECTIVES: The present study analyzes the association between the motivation to change and the cognitive-behavioral group intervention, in terms of dropouts and relapses, in a sample of male pathological gamblers. The specific objectives were as follows: (a) to estimate the predictive value of baseline University of Rhode Island Change Assessment scale (URICA) scores (i.e., at the start of the study) as regards the risk of relapse and dropout during treatment and (b) to assess the incremental predictive ability of URICA scores, as regards the mean change produced in the clinical status of patients between the start and finish of treatment. METHOD: The relationship between the URICA and the response to treatment was analyzed by means of a pre-post design applied to a sample of 191 patients who were consecutively receiving cognitive-behavioral group therapy. The statistical analysis included logistic regression models and hierarchical multiple linear regression models. RESULTS: The discriminative ability of the models including the four URICA scores regarding the likelihood of relapse and dropout was acceptable (area under the receiver operating haracteristic curve: .73 and .71, respectively). No significant predictive ability was found as regards the differences between baseline and posttreatment scores (changes in R(2) below 5% in the multiple regression models). CONCLUSIONS: The availability of useful measures of motivation to change would enable treatment outcomes to be optimized through the application of specific therapeutic interventions.

The facial and subjective emotional reaction in response to a video game designed to train emotional regulation (Playmancer).

Several aspects of social and emotional functioning are abnormal in people with eating disorders. The aim of the present study was to measure facial emotional expression in patients with eating disorders and healthy controls whilst playing a therapeutic video game (Playmancer) designed to train individuals in emotional regulation. Participants were 23 ED patients (11 AN, 12 BN) and 11 HCs. ED patients self reported more anger at baseline but expressed less facial expression of anger during the Playmancer game. The discrepancy between self-report and non-verbal expression may lead to problems in social communication.

Video games as a complementary therapy tool in mental disorders: PlayMancer, a European multicentre study.

BACKGROUND: Previous review studies have suggested that computer games can serve as an alternative or additional form of treatment in several areas (schizophrenia, asthma or motor rehabilitation). Although several naturalistic studies have been conducted showing the usefulness of serious video games in the treatment of some abnormal behaviours, there is a lack of serious games specially designed for treating mental disorders. AIM: The purpose of our project was to develop and evaluate a serious video game designed to remediate attitudinal, behavioural and emotional processes of patients with impulse-related disorders. METHOD AND RESULTS: The video game was created and developed within the European research project PlayMancer. It aims to prove potential capacity to change underlying attitudinal, behavioural and emotional processes of patients with impulse-related disorders. New interaction modes were provided by newly developed components, such as emotion recognition from speech, face and physiological reactions, while specific impulsive reactions were elicited. The video game uses biofeedback for helping patients to learn relaxation skills, acquire better self-control strategies and develop new emotional regulation strategies. In this article, we present a description of the video game used, rationale, user requirements, usability and preliminary data, in several mental disorders.

Comparison between immigrant and Spanish native-born pathological gambling patients.

The study compared clinical, psychopathological, and personality profiles between immigrants and Spanish native-born pathological gambling patients. A total of 1,601 native-born and 133 immigrant patients attending treatment at a specialized hospital unit were administered a battery of questionnaires during clinical assessment. Outcome measures were compared between both groups and the incremental predictive accuracy of the area of origin was examined using a regression model. Native-born Spaniards showed a mean 2.6 yr. greater duration of the disorder, while immigrants scored higher on South Oaks Gambling Screen, frequency of going to casinos, and total money spent (in a single day and/or to recover losses). General psychopathology and personality scores did not differ between the cohorts. However, immigration from Asia had a statistically significantly incremental validity for pathological gambling in South Oaks Gambling Screen scores. Both cohorts shared more similarities than differences in their gambling profiles.

Compulsive Sexual Behavior Online and Non-online in Adult Male Patients and Healthy Controls: Comparison in Sociodemographic, Clinical, and Personality Variables.

Background and Aims: Compulsive sexual behavior (CSB) is characterized by a persistent pattern of failure to control sexual impulses, resulting in repetitive sexual behavior over a prolonged period that causes marked discomfort in personal, family, social, school, work or in other functional areas. The evolution of the worldwide incidence of this disorder warrants further studies focused on examining the characteristics of the affected people. The purpose of this study was to compare online compulsive sexual behavior (when the problematic sexual practices were online) and non-online compulsive sexual behavior (when the problematic sexual practices were in-person) patients (OCSB and non-OCSB, respectively), and healthy controls in terms of sexual behavior, sociodemographic variables and psychopathology and personality characteristics. Method: A sample of 80 CSB male patients consecutively admitted to our Behavioral Addictions Unit and 25 healthy male controls, participated in the study. The CSB group was comprised by 36 online CSB patients (mean age 42.25, SD: 10.0) and 44 non-online CSB patients (mean age 43.5, SD: 11.9). Scores on the Sexual Compulsivity Scale, Temperament and Character Inventory-Revised, Symptom CheckList-90 Items-Revised, State-Trait Anxiety Index, and additional demographic, clinical, and social/family variables related to sexual behaviors between the three groups were compared. Results: When compared with healthy controls, both clinical groups showed higher psychopathology in all measures as well as higher harm avoidance and self-transcendence and lower self-directness and cooperativeness. When comparing OCSB and non-OCSB patients, results showed that non-OCSB patients exhibited higher prevalence of sexually transmitted diseases, higher percentage of homosexual and bisexual orientation and higher scores in anxiety and in sexual impulse control failure. Conclusion: Both online and non-online CSB patients may experience a variety of comorbid psychological and medical problems. Patients with non-OCSB may suffer more consequences that are negative. Therefore, these results should be considered when designing the most convenient therapeutic approach. Whether sexual orientation plays a role in treatment needs and treatment response in CSB, should be further explored in future studies.

Local Resection in Choroidal Melanoma: A Review.

Surgical resection is widely used to treat small tumours located in the iris and the ciliary body, due to the accessibility of these sites. By contrast, surgical removal of choroidal tumours is substantially more challenging, which is why this procedure is performed only at specialised centres. In the present article, we review the literature on surgical resection of choroidal tumours, which can be performed as endoresection (ab interno) or transscleral resection (ab externo). An important aim of this review is to describe and compare the two approaches in terms of visual outcomes, survival rates, and complications. Both approaches are indicated for the removal of large tumours (thickness > 8 mm) with small base diameters. Surgical resection of the tumour allows clinicians to obtain valuable histopathologic and cytogenetic data from the specimen and eliminates the risks associated with radiotherapy. However, both of these surgical approaches are technically challenging procedures involving the risk of severe early and late postoperative complications.

Suicide attempts in anorexia nervosa subtypes.

OBJECTIVE: The risk for suicide attempts is elevated in anorexia nervosa (AN), yet we know little about the relation between suicide and personality in this group. We explored the prevalence of lifetime suicide attempts in women with AN and compared those who had and had not attempted suicide on eating disorder symptoms, general psychopathology, and personality both relative to a healthy control group and then across AN subtypes. METHOD: One hundred four outpatients with restricting AN, 68 outpatients with purging AN, and 146 comparison individuals participated in the study. RESULTS: The prevalence of suicide attempts differed significantly across the 3 groups (P = .003), with 0% in the controls, 8.65% in the restricting AN group, and 25.0% in the purging AN group. Depression measures were elevated in those with suicide attempts. Within the restricting AN group, those who attempted suicide scored significantly higher on Phobic Anxiety, measured by means of the Symptom Checklist-Revised, than those who did not (P = .001). CONCLUSION: The presence of purging and depressive symptoms in individuals with AN should increase vigilance for suicidality; and among restrictors, greater anxiety may index greater suicide risk.
