Abstract
Synaptosomes are isolated nerve terminals. They represent an extremely attractive in vitro model system to study synaptic physiology since they preserve morphological and functional characteristics of the synapse. As such they have been used to investigate synaptic dysfunctions associated with neuropathologies like Alzheimer's disease. In the present work two simple methodologies for isolating synaptosomal-enriched fractions were compared for the first time. The starting points of both protocols were rat cortical or hippocampal homogenized tissues that underwent several differential centrifugation steps followed by a final purification of synaptosomal-enriched fractions using either a Percoll gradient or a Sucrose gradient. Comparison of the fractions obtained was carried out, using both biochemical and electron microscopy approaches. In the biochemical analysis the protein levels of pre-synaptic, post-synaptic, nuclear and mitochondrial markers were evaluated. Additional characterization of the synaptosomal-enriched fractions was performed using transmission electron microscopy. In summary, the results indicate that under the conditions tested the Sucrose based protocol is more efficient for the isolation of synaptosomal-enriched fractions from both neuronal tissues, being particularly efficient for hippocampus that is a less abundant brain tissue. Further, the sucrose protocol apparently results in a higher yield of viable synaptosomes suitable for further assays, including structural and functional studies of synapses; making this an attractive procedure to study processes associated with neuropathologies.

Abstract
INTRODUCTION Immunosuppression has a pivotal role in kidney transplantation. The new prolonged-release formulation of tacrolimus was developed to provide a more convenient once-daily dosing to improve patient adherence. METHODS We selected 60 stable kidney transplant recipients who underwent tacrolimus conversion in our unit. Conversion was made on a 1 mg:1 mg basis in 66.7% of patients (n = 40) and on a 1 mg:1.1 mg basis in the remaining 33.3% (n = 20). Clinical and analytical data at conversion and postconversion was analyzed retrospectively to evaluate the efficacy and safety of conversion from tacrolimus twice-daily to once-daily formulation. RESULTS A significant reduction in tacrolimus blood levels requiring an increase in tacrolimus daily dose was observed postconversion. Postconversion tacrolimus blood level reduction >25% was significantly higher in the conversion group 1 mg:1 mg basis (P = .004). In patients converted 1 mg:1 mg, female sex and higher tacrolimus level at conversion were significant risk factors for a reduction >25% in tacrolimus blood levels after conversion. No significant change was detected between mean glomerular filtration rate at conversion (57 mL/min) and at 3, 6, and 9 months postconversion. CONCLUSIONS Once-daily tacrolimus at similar doses to the twice-daily formulation is an efficient and safe treatment option. Conversion made on 1 mg:1.1 mg basis seems advantageous at least in some patients.

Abstract
INTRODUCTION Peritoneal dialysis is the dialytic method of choice in chronic end-stage renal disease in children. This study main purpose was to characterize the long-term survival of a pediatric population who began peritoneal dialysis within the first two years of life. MATERIAL AND METHODS A descriptive and retrospective study was performed in a portuguese nephrology and renal transplantation pediatric unit, between January 1991 and August 2014. End-stage renal disease etiology, mortality, comorbidities and complications of peritoneal dialysis and end-stage renal disease, growth and psychomotor development were evaluated. RESULTS Twenty children started peritoneal dialysis within the first two years of life. There were six deaths, but no deaths of children with primary chronic kidney disease were registered over the past decade. The 14 living children were characterized; 13 were males. Congenital abnormalities of the kidney and urinary tract were the leading etiology of chronic kidney disease (45%). The average age start of peritoneal dialysis was 6.1 months; six children started before 30 days of life. Peritonitis was the most frequent cause of hospitalization. Ten children were transplanted at an average age of 5.3 years. All of the children who are still in peritoneal dialysis have short stature, but nine of the transplanted have final height within the expected for their mid-parental height target range. Nine (64%) had some type of neurodevelopmental delay. DISCUSSION Peritoneal dialysis is a technique possible and feasible since birth, as evidenced in the study, as more than half of children successfully started it before 6 months of life. It allows long-term survival until the possibility of renal transplantation despite the associated morbidity, including peritonitis and complications of chronic renal disease. The ten transplanted children improved their growth, recovered from chronic anemia and improved dyslipidemia, compared with the period of dialysis. However, the average waiting time until the renal transplant was 5.3 years higher than other international centers. CONCLUSION These data support the use of peritoneal dialysis from birth, but complications and the worst growth reflect the need to develop strategies to optimize care relating to nutrition, growth and development and to reduce pre-transplant time.

Abstract
Urban ants cause many losses to human society, and they represent a potential threat to public health in hospital environments due to their ability to transport pathogenic organisms. We evaluated several ecological parameters (richness, abundance, constancy, and evenness), their fluctuation during the seasons, and identified species that occur outside the natural range of the ant fauna of a hospital environment, as support for future management strategies. Ant sampling was held every 2 months by using attractive bait traps in the morning and evening, leading to the sampling of 10,342 individuals belonging to six subfamilies and 26 species. Myrmicinae showed higher richness (n = 12) and abundance (n = 7336), with Pheidole susannae Forel being the most abundant species. The most constant species (100%) were P. susannae and Tetramorium simillimum (Smith). Among the most abundant species, Monomorium floricola (Jerdon) and Tapinoma melanocephalum (Fabricius) are considered as species that occur outside the natural range. No difference was observed between species richness and abundance. The Shannon (2.247), dominance (0.1395) and evenness indices (0.6897) indicated a stability of the community throughout the year with high diversity and low dominance of species. The sampled data constitute a new series of information on a long-term ecological approach to support future management strategies in hospital environments and allow for more efficient pest control.

Abstract
IntroductionJealousy is a complex emotional state and some degree is considered normal in mature love, but when does it become destructive in a relationship? There's a thin line between what is normal and what is pathologic. Pathological jealousy differs from normal by its intensity and irrationality. Obsessive and delusional jealousies are different types of pathological jealousy, difficult to distinguish, which is important, since they have different treatment. Despite the differences, both result in significant distress and carry the risk of homicide/suicide, so it's a matter deserving the psychiatrists’ attention.ObjectiveExplore the psychopathological differences between obsessive and delusional jealousy and list the characteristics and difficulties in the approach to pathological jealousy.MethodsThe results were obtained searching literature included on the PubMed and Google Scholar platforms.ResultsDelusional jealousy is characterized by strong and false beliefs that the partner is unfaithful. Individuals with obsessive jealousy suffer from unpleasant and irrational jealous ruminations that the partner could be unfaithful, accompanied by compulsive checking of partners’ behavior. This jealousy resembles obsessive-compulsive phenomenology and should be treated with SSRIs and cognitive-behavioral therapy. Delusional jealousy is a psychotic disorder and should be treated with antipsychotics.ConclusionThe common issue in pathological jealousy is the problem of adherence to treatment and bad prognosis. In order to achieve better treatment outcomes, we should follow-up the patient regularly. One key factor is to explore the psychopathology and motivate the sufferer for the proper pharmacological and psychotherapeutic interventions, trying to reduce the suffering caused by ideas of unfaithfulness.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionCatatonia, described by Kahlbaum in 1874, is usually seen as a type of schizophrenia, but it can also occur in a wide range of other psychiatric/organic disturbances. There is a documented association between dementia and catatonia, in all phases of cognitive impairment.AimsLiterature review and discussion about Catatonia, regarding a case report.MethodsClinical interviews and literature review in PUBMED database.Results (case report)Female patient, 89 years old, without psychiatric history, was diagnosed with dementia 5 months prior to episode. On admission, she presents with prostration, mutism and refusal to eat/drink. Laboratory studies were normal and TC-CE shows signs of an old stroke in left temporo-parietal region and diffuse signs of ischemic leucoencephalopathy. At psychiatric evaluation, she was stuporous, unreactive to pain, mute, not following verbal commands, keeping her eyes closed and resisting attempts to open her eyelids. She had global rigidity, axial and limbs, and maintains the postures the examiner puts her into for long periods. She was already given chlorpromazine, without improvement. Then she takes diazepam 10 mg iv, with remission of the state.ConclusionsAlthough catatonia usually presents with drama, clinicians often forget to consider it in differential diagnosis, probably because of its traditional association with schizophrenia. A promptly diagnostic is crucial to provide adequate treatment, avoiding drugs that can worsen/perpetuate the clinical state. Some authors even support the idea that motor features associated with end-line dementias may correspond to lorazepam-responsive catatonia, in which treatment may have a tremendous impact worldwide.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionThe idea that some people may not be able to control their stealing impulses emerged in 1838, when Esquirol and Marc coined the term Kleptomanie. Although there are not many studies regarding this issue, becoming therefore difficult to establish epidemiological data, various clinical samples suggest a high prevalence of the disorder. As the problem most likely become chronic when left untreated, the diagnostic approach is very important.AimsLiterature review and discussion about kleptomania, regarding a case report.MethodsClinical interviews and literature review in PUBMED database.Results (case report)Female patient, 62 years, with history of Personality Disorder and Persistent Depressive Disorder, confesses in psychiatric appointment that she had been caught stealing. She says that she has this “addiction to steal” since childhood, always stealing cheap stuff, that she does not need, usually giving it away to other people. She has this behavior as she feels an unexpected and irresistible impulse to steal, with increasing anxiety, which relieves when action is consumed. Afterwards she experiences feelings of shame and guilt. The patient symptoms appear to get worse in depressive relapses.ConclusionsRegarding individual, family and social impact of kleptomania is essential to assess it and to treat it promptly. Most of the patients are ashamed of their behavior, so they may not self-report. There are few and controversial data concerning treatment, but it is widely accepted that co-morbidity with mood disorders or substance use disorders is common and may interfere with treatment.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
BACKGROUND HLA alloimmunization is caused by sensitization events (SEs), such as transfusion, pregnancy, or previous organ transplantation, and the effects of particular SEs have not been thoroughly studied. Our aim was to evaluate how each SE affected HLA alloimmunization by considering Luminex assays. METHODS Sera from 722 kidney transplantation candidates were screened per protocol by means of Luminex assays to determine the presence of anti-HLA class I/II antibodies; positive sera underwent single-antigen assay to determine the presence of specific antibodies against HLA A, B, C, DR, DQ, DP loci (positivity if median fluorescence intensity values were >1,000). The effect of each SE was analyzed considering only patients exposed to 1 kind of sensitization. RESULTS In the 453 candidates with ≥1 SE, anti-HLA class I positivity rates were significantly higher in patients with previous transfusion (18.9%; P = .014), pregnancy (38.3%; P < .001) or transplant (75%; P < .001) compared with those with no SE (similar results for class II). The strength (median fluorescence intensity) of specific antibodies was significantly higher in patients with previous transplantation than in those with previous transfusion for HLA-A (8,017 vs 2,302; P = .02), HLA-B (7,765 vs 2,901; P = .018), and HLA-DR (9,835 vs 2,060; P = .003). Other anti-HLA antibody strengths were similar between patients with previous pregnancy or transplantation. CONCLUSIONS Presence of any SE analyzed was associated with a higher prevalence of anti-HLA antibodies for class I ± II compared with nonsensitized patients. Transplantation had the strongest immunization effect on both classes, followed by pregnancy and then transfusion.

Abstract
INTRODUCTION Allograft nephrectomy (AN) is associated with a high number of surgical complications. Some authors advocate that early nephrectomy (<1 year) is associated with fewer complications. Intracapsular (ICAN) and extracapsular AN (ECAN) might have a different impact on allosensitization and surgical outcomes. Our goal was to compare surgical outcomes between early and late AN in our institution and to compare ICAN and ECAN in terms of surgical outcomes and panel reactive antibodies (PRA) variation. MATERIALS AND METHODS Between January 2000 and October 2012, we performed 104 AN at our institution (32 early and 72 late). Comparisons between early and late AN, and, within the latter, between the 2 different techniques were sought. Statistical analysis was performed for sample description, group comparison and %PRA variation. RESULTS Among the 104 patients with a mean age of 47.9 ± 14.2 years, 54 were men. Age, gender, body mass index, and number of previous transplants were similar between early and late AN and between ICAN and ECAN patients. Late AN was associated with less blood loss (293.4 ± 229.0 vs 414.3 ± 349.5 mL; P = .03), shorter hospital stay (12.8 ± 14.5 vs 26.8 ± 26.5; P < .05), and fewer complications (22.2% vs 59.3%; P < .05). The chance of being relisted for transplantation was similar (50.0% in early vs 59.7% in late AN; P = .7). When comparing ICAN and ECAN, there was no difference in surgical outcomes. The %PRA variation between the 2 techniques was comparable (-1.2 ± 10.6 ICAN vs -0.5 ± 15.9 ECAN; P = .8), as was the chance of being relisted for transplantation (60.5% ICAN vs 58.6% ECAN; P = .8). CONCLUSIONS Early AN was associated with a greater number of surgical complications. Nevertheless, the number of AN patients returning to the active waiting list was similar between early and late AN groups. ICAN and ECAN had similar surgical and postoperative outcomes, although a bias may be present because some conversions from ECAN to ICAN occurred owing to technical issues. As in other studies, ICAN did not seem to affect allosensitization or jeopardize the chance of being relisted for transplant when compared with ECAN.

Abstract
The stability of the Co-Cr-Mo dental alloy immersed in artificial salivas (pH 6.7) was investigated over 24 h. Three artificial salivas have been studied: saline saliva (saliva I); saline saliva buffered with phosphate ions (saliva II) and saliva II plus mucin molecules (saliva III). For all the systems, open circuit potential shift positively over 24 hours of immersion. Data extracted from the steady-state polarization curves demonstrated that the Co-Cr-Mo alloy has higher corrosion potential in saliva III, lower corrosion potential in saliva I and lower initial corrosion resistance in saliva III. After 24 hours of immersion in the artificial salivas, the Co-Cr-Mo alloy presents high corrosion stability, due to the protective action created by the presence of corrosion products. From the analysis of the breakdown potential it was concluded that, the presence of the phosphate ions and mucin promote the oxidation process, inducing the formation of etch pits. Regarding the effect of the mucin concentration in the corrosion behaviour of the Co-Cr-Mo dental alloy, it was observed a negative shift in the corrosion potential, pointing to a cathodic inhibitor role for the mucin molecules. Nevertheless, no correlation between the mucin concentration and corrosion rate was possible to establish.

Corrales JJ, Almeida M, Martín-Martín L, Miralles JM, Orfao A. Testosterone replacement therapy in hypogonadal men is associated with increased expression of LAMP-2 (CD107b) by circulating monocytes and dendritic cells. Clin Endocrinol (Oxf) 2014; 80:577-84. [PMID: 24111582 DOI: 10.1111/cen.12338] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2013] [Revised: 08/10/2013] [Accepted: 09/17/2013] [Indexed: 01/04/2023]
Abstract
BACKGROUND Accumulated experimental data indicates that androgen therapy has effects on inflammation and protects from autoimmune disorders. Despite this, the in vivo effects of testosterone replacement therapy on human antigen-presenting cells-for example, monocytes and dendritic cells- remain unknown. OBJECTIVE, DESIGN AND PATIENTS We monitored the effects of testosterone replacement therapy on the number and the functionality -as assessed by the expression of CD107b (lysosome-associated membrane protein 2, LAMP-2)- of resting and in vitro-stimulated peripheral blood (classical and nonclassical) monocytes and dendritic cells (myeloid and plasmacytoid) from hypogonadal men. RESULTS Our results show that testosterone replacement therapy induces overexpression of CD107b by circulating monocytes and dendritic cells from hypogonadal men, both under resting (i.e. nonstimulated) conditions and after in vitro stimulation. CD107b overexpression mostly involved monocytes and in vitro stimulation with CpG oligodeoxynucleotides. Of note, a strong correlation was found between CD107b expression on monocytes and serum gonadotrophins levels. CONCLUSION These results support the existence of an effect of testosterone therapy, and potentially also of gonadotrophins, on circulating antigen-presenting cells.
