Psychiatric symptoms are the complications most often ignored in patients who suffered a stroke. Depression is the most common psychiatric complication in post-stroke patients with a prevalence of about 20–50% in the first year and with a peak in first six months after the stroke. Depression in turn, constitutes itself a factor of cerebrovascular risk. Despite its high prevalence this disorder remains under diagnosed and under treated. One explanation for this fact is that depressive symptoms are often misinterpreted as consequences of stroke itself. This reality is even more striking in patients with aphasia. Poststroke depression (PSD) results from the interaction between biological, as the location of the stroke, social and psychological factors. The presence of this disorder is associated with deleterious consequences for rehabilitation process. These patients suffer more often from attention deficits, cognitive difficulties, lower response to rehabilitation programs, poor quality of life and increased mortality.

The term refeeding syndrome has been used to describe the adverse consequences that can occur in all malnourished patients in the early stages of nutrition repletion whether the method of refeeding is oral, enteral or parenteral. Those consequences include acute thiamine deficiency resulting in Wernicke's encephalopathy and Korsakoff syndrome, with the potential for permanent cognitive impairment; hypophosphatemia, hypokalemia, hypomagnesemia and fluid overload resulting in cardiac failure. Adaptive changes in metabolism occur during a period of starvation or fasting: levels of glucose fall within 24 to 72 hours, as response, glucagon levels rise and insulin concentrations decrease. Glucose levels are maintained by glycogenolysis at first and gluconeogenesis latter. The reintroduction of nutrition leads to a switch from fat to carbohydrate metabolism and an increase of insulin concentration. Insulin stimulates the movement of potassium, phosphate, and magnesium into the cell leading to its depletion in extracellular compartment. Reactivation of carbohydrate metabolism increases degradation of thiamine, a cofactor required for cellular enzymatic reactions in Kreb's cycle. Deficiency in all these nutrients can then occur. Patients with anorexia nervosa are at risk of suffering from refeeding syndrome. This psychiatric disorder causes potentially life-threatening, physical complications and has the highest mortality rate among psychiatric disorders. The purpose of this review is to clarify recommendations for prevention and treatment of refeeding syndrome in anorexia nervosa.

Dementia is a syndrome–usually of a chronic or progressive nature–in which there is deterioration in cognitive function beyond what might be expected from normal ageing (WHO). As the world population ages, the number of people afflicted with dementing illnesses will increase. This neurodegenerative disease is one of the major causes of disability and dependency among older people worldwide. Brain single-photon emission computed tomography (SPECT) allows the study of regional cerebral blood flow, providing functional information. Each of the different types of dementia has a distinct blood flow pattern that is revealed with SPECT imaging and which can be used for differential diagnoses. This imaging technique can also be used to differentiate dementia from pseudodementia. The use of SPECT has been recommended in various guidelines to help in differential diagnosis of dementia. The National Institute for Health and Clinical Excellence in the UK recommend the use of SPECT or positron emission tomography (PET) to help differentiate Alzheimer's disease (AD) from frontotemporal dementia and vascular dementia when there is diagnostic doubt (NICE, 2006). The European Federation of the Neurological Societies guidelines for diagnosis also supports the use of FDG-PET (18F fluorodeoxyglucose positron emission tomography) or perfusion SPECT when clarifying a diagnosis of AD. This review describes the utility of perfusion SPECT in differential diagnosis of neurodegenerative dementias.

The World Health Organization (WHO, 2006) defines sexual abuse as the involvement of a child in sexual activity that he or she does not fully comprehend, being unable to give informed consent to, or for which the child is not developmentally prepared, or else that violates the laws or social taboos of society. In Portugal, the law that regulates the sexual abuse of underage people (minors) is enclosed in crimes of sexual auto-determination, which are described as child sexual abuse (article 171°) and sexual acts with a teenager (article 172°), and those are applied to the person that has copulation, anal intercourse and oral intercourse with underage abusing from their inexperience. Our objective is to investigate the profile of sexual abusers of minors, namely, the socio-demographic features, clinical correlations, and the level of penal responsibility of sexual offenders who were referred by court to forensic psychiatric assessment in the Institute of Legal Medicine of the City of Coimbra. Moreover, verify if these individuals present mental disorders at the time of the offence. The present study is of descriptive nature, being based on the observation and consultation of 30 clinical processes of sexual abusers. All written reports were obtained from 2005 to 2015 by court-appointed psychiatric experts on individuals that have been charged of committing sexual crimes against minors and referred to the main forensic institute in the city of Coimbra. This study will contribute to the increase of more information on these offenders, promoting the development of more adequate contingency plans for this population.

The World Health Organization (WHO, 2004) stresses the importance of home patient visiting as an answer to the epidemiologic, demographic, social and economic challenges that the world is facing.

The severe psychiatric patients are a risk group and often need domicile consultation and visiting. The domicile consultation approach favors the clinical, social and familiar support as well as promotes the integration and the recovering of the patients with mental problems, preventing the relapses and the hospital admissions of these patients.

This study, of descriptive nature, is based on the observation and consultation of 287 clinical processes of patients inserted in the domicile consultation program designed by the Department of Psychiatry and Mental Health of Sousa Martins Hospital, ULS Guarda, which covers the 7th biggest district in Portugal (in a universe of 18), between July and September 2015.

The main goal of this study is to characterize and analyze the profile of the population, which is followed by the community mental health team of our Department, namely, the socio-demographic and clinic features, in order to improve the assistance practice in the future.

A new fossil site in a previously unexplored part of western Madagascar (the Beanka Protected Area) has yielded remains of many recently extinct vertebrates, including giant lemurs (Babakotia radofilai, Palaeopropithecus kelyus, Pachylemur sp., and Archaeolemur edwardsi), carnivores (Cryptoprocta spelea), the aardvark-like Plesiorycteropus sp., and giant ground cuckoos (Coua). Many of these represent considerable range extensions. Extant species that were extirpated from the region (e.g., Prolemur simus) are also present. Calibrated radiocarbon ages for 10 bones from extinct primates span the last three millennia. The largely undisturbed taphonomy of bone deposits supports the interpretation that many specimens fell in from a rock ledge above the entrance. Some primates and other mammals may have been prey items of avian predators, but human predation is also evident. Strontium isotope ratios (87Sr/86Sr) suggest that fossils were local to the area. Pottery sherds and bones of extinct and extant vertebrates with cut and chop marks indicate human activity in previous centuries. Scarcity of charcoal and human artifacts suggests only occasional visitation to the site by humans. The fossil assemblage from this site is unusual in that, while it contains many sloth lemurs, it lacks ratites, hippopotami, and crocodiles typical of nearly all other Holocene subfossil sites on Madagascar.

This study assessed the in vitro anthelmintic (AH) activity of methanol and acetone:water leaf extracts from Annona squamosa, A. muricata and A. reticulata against Haemonchus contortus eggs. The egg hatch test was used to determine the effective concentrations required to inhibit 50% of eggs hatching (EC50). The role of polyphenols on AH activity was measured through bioassays with and without polyvinylpolypyrrolidone (PVPP). Methanolic extracts mainly caused the death of eggs at the morula stage (ovicidal activity). Meanwhile, acetone:water extracts caused egg-hatching failure of developed larvae (larvae failing eclosion (LFE) activity). The lowest EC50 values against H. contortus eggs were observed for the methanolic extracts from A. reticulata and A. muricata (274.2 and 382.9 µg/ml, respectively). From the six extracts evaluated, the methanolic extracts of A. muricata, A. reticulata and A. squamosa showed the highest ovicidal activity, resulting in 98.9%, 92.8% and 95.1% egg mortality, respectively. When the methanolic extract of A. squamosa was incubated with PVPP, its AH activity increased. Similarly, when acetone:water extracts of A. muriata and A. reticulata were incubated with PVPP, their LFE activity increased. Alkaloids were only evident in methanolic extracts, irrespective of PVPP incubation. The presence of acetogenins was not observed. In conclusion, methanolic extracts obtained from leaves of A. muricata, A. reticulata and A. squamosa showed ovicidal activity affecting the morula of H. contortus eggs, with minor LFE activity. Meanwhile, acetone:water extracts showed mostly LFE activity, with a lower proportion of ovicidal activity.
