Introduction
The comorbidity between Schizophrenia and Obsessive-Compulsive Symptoms represents almost 25% of schizophrenic patients and it is believed that almost 12% match the diagnostic criteria for Obsessive-Compulsive Disorder. Some second-generation antipsychotics may worsen or even induce those symptoms, which makes the treatment of this patients a difficult challenge.
ObjectivesTo assess the link between Schizophrenia and Obsessive-Compulsive Symptoms, to discuss the diagnostic challenges and treatment options. To present a clinical case report of a schizophrenic patient with Obsessive-Compulsive Symptoms, which improved with proper treatment.
MethodsWe performed a non-systematic review of the existent literature with the keywords “Schizophrenia” and “Obsessive-Compulsive Symptoms”. Description of a clinical case report.
ResultsWe present the case report of a male, 21 years old, single, diagnosed with Schizophrenia. In the past year, he was admitted twice in a psychiatric ward for persecutory and mystic delusions, which lead him to erratic behaviour. Since his adolescence he manifested repeated washing and compulsive cleaning associated with the fear of being contaminated with multiple diseases. Those compulsions worsened when he started being treated with antipsychotics. However, with therapeutic adjustments and with the introduction of an antidepressant we were able to control those symptoms.
ConclusionsSome antipsychotics may induce or even aggravate Obsessive-Compulsive Symptoms in psychotic patients. It is of extreme relevance to differentiate those symptoms as comorbid in Schizophrenia or if they existed prior to the first positive symptoms, since they can be representative of an Obsessive-Compulsive Disorder. Understanding this diagnostic and treatment complexity enables us to be more familiar with the development of Obsessive-Compulsive Symptoms in schizophrenic patients.

Introduction
Difficult patients are not something new and we can find innumerous definitions for this concept. However, they form a very heterogenous group and we need a less abstract definition focused more on the clinical reality and the difficulties experienced by patients and mental health professionals.
ObjectivesOur goal was to find a more precise and clinical definition of the difficult patient based on quantitative measures using a statistical analysis of a series of hospitalizations.
MethodsA cluster analysis of our hospital’s in-patient treatment from the last 5 years was made concerning the duration of the stay and the number of previous hospitalizations.
ResultsA sample of 8576 inpatient treatment episodes was used. 52.4% were male and 47.6% female patients between the age of 15 and 103 years old. The length of the treatment varied from 0 to 1007 days and the number of previous hospitalizations from 0 to 109; excluding the outliers the means were, respectively, 21 days and 2 previous hospitalizations.
The cluster analysis excluded 85 episodes and it found the presence of 3 clusters, being the number 1 the wider one (n=5861 episodes) and the other quite similar.
The Cluster 1 was characterized by a smaller length of hospital stay and number of hospitalizations; the Cluster 2 was defined by the episodes with the highest number of previous hospitalizations (`x =8.77) and the Cluster C by the longest hospital stays (`x =58.09 days). With a Kruskal-Wallis test we found both variables statistically different between all clusters (p<0.001). In Cluster 2 and 3, respectively, we found that 40,24% and 34.61% was taking the medication before being hospitalized, 6.42% and 3.15% were compulsive hospitalizations, and 40.5% and 21.89% had LAI prescribed.
Concerning the diagnosis, Cluster 1 had more Depression, Neurotic and Somatoform disorders; Cluster 2 more Bipolar and Intellectual disability disorders and Cluster 3 more Dementia and Delusional disorders. Substance use disorders and Personality disorders were found more common in both Cluster 1 and 2, Schizophrenia in Cluster 2 and 3 and Psychosis non specified in Cluster 1 and 3.
ConclusionsWe can say Cluster 1 comprises the non-difficult patients and it’s not surprising that it includes more Depression and Neurotic and Somatoform disorders. The other diagnostic distributions among clusters were also expected and we can also theorize that Cluster 3 had higher percentages of social cases. Treatment with LAI is linked to a decrease in rehospitalizations and we found that in the majority of these episodes it wasn’t been applied. This research is important in order to identify the difficult patients and what challenges they can bring to the mental health services. Creating these patients’ profile will allow us to better understand their needs to create guidelines for a personalized inpatient treatment and to improve community services to prevent the rehospitalizations and prolonged hospital stays.

The dietary inclusion of feed additives to improve the carcass characteristics of the final product is of great importance for the pork production chain. The aim of our study was to evaluate the effects of the association of ractopamine (RAC) and conjugated linoleic acid (CLA) on the performance traits of finishing pigs during the last 26 days prior to slaughter. In total, 810 commercial hybrid barrows were used. Animals were distributed among treatments according to a randomised block design in a 3 × 3 factorial arrangement, with three RAC levels (0, 5 or 10 ppm) and three CLA levels (0, 0.3 or 0.6%). Pigs fed the diet with 5 ppm RAC had higher average daily feed intake (ADFI) (2.83 kg; P < 0.05) when compared with those fed 10 ppm RAC and the control diet (2.75 and 2.74 kg, respectively). Lower ADFI values (P < 0.01) were observed with the diets containing CLA compared with the control diet with no CLA (2.73 and 2.75 v. 2.85 kg/day, respectively). The average daily weight gain of pigs fed 5 and 10 ppm RAC was +148 and +173 g/dayhigher (P < 0.001), respectively, than those fed the control diet. Dietary RAC levels influenced (P < 0.001) feed conversion ratio (FCR), which was reduced as RAC levels increased, with the pigs fed 10, 5 and 0 ppm RAC presenting FCR values of 2.57, 2.71 and 3.05, respectively. FCR also improved (P < 0.05) with the inclusion of 0.6% CLA relative to the control diet (2.70 v. 2.84, respectively). There was a significant interaction between CLA × RAC levels (P < 0.01) for final BW, loin eye area (LEA) (P < 0.05) and backfat thickness (BT) (P < 0.05). The treatments containing 10 ppm RAC + 0.6% or 0.3% CLA increased LEA and reduced BT. In conclusion, the level of 10 ppm inclusion of RAC increased the overall performance parameters of pigs and therefore improved production efficiency. The combined use of RAC and CLA promoted a lower feed conversion ratio as well as better quantitative carcass traits, as demonstrated by the higher LEA and lower BT. The dietary inclusion of CLA at 0.3% improved feed efficiency, however, without affecting LEA or BT yields.

Hepatocytes constitute the majority of hepatic cells, and play a key role in controlling systemic innate immunity, via pattern-recognition receptors (PRRs) and by synthesizing complement and acute phase proteins. Leishmania infantum, a protozoan parasite that causes human and canine leishmaniasis, infects liver by establishing inside the Kupffer cells. The current study proposes the elucidation of the immune response generated by dog hepatocytes when exposed to L. infantum. Additionally, the impact of adding leishmanicidal compound, meglumine antimoniate (MgA), to parasite-exposed hepatocytes was also addressed. L. infantum presents a high tropism to hepatocytes, establishing strong membrane interactions. The possibility of L. infantum internalization by hepatocytes was raised, but not confirmed. Hepatocytes were able to recognize parasite presence, inducing PRRs [nucleotide oligomerization domain (NOD)1, NOD2 and Toll-like receptor (TLR)2] gene expression and generating a mix pro- and anti-inflammatory cytokine response. Reduction of cytochrome P 450s enzyme activity was also observed concomitant with the inflammatory response. Addition of MgA increased NOD2, TLR4 and interleukin 10 gene expression, indicating an immunomodulatory role for MgA. Hepatocytes seem to have a major role in coordinating liver's innate immune response against L. infantum infection, activating inflammatory mechanisms, but always balancing the inflammatory response in order to avoid cell damage.

The Vista Variables in the Vía Láctea (VVV) ESO Public Survey is an ongoing time-series, near-infrared (IR) survey of the Galactic bulge and an adjacent portion of the inner disk, covering 562 square degrees of the sky, using ESO's VISTA telescope. The survey has provided superb multi-color photometry in 5 broadband filters (Z, Y, J, H, and Ks), leading to the best map of the inner Milky Way ever obtained, particularly in the near-IR. The main part of the survey, which is focused on the variability in the Ks-band, is currently underway, with bulge fields observed between 34 and 73 times, and disk fields between 34 and 36 times. When the survey is complete, bulge (disk) fields will have been observed up to a total of 100 (60) times, providing unprecedented depth and time coverage in the near-IR. Here we provide a first overview of stellar variability in the VVV data.
