Background: In addition to determining the cumulative incidence and risk factors for early seizures (ES), late seizures (LS) and post stroke epilepsy (PSE), we aimed at checking if ES represented a risk factor for epilepsy and if early treatment after ES prevented the occurrence of subsequent seizures. Methods: This study was part of a 2-year prospective community-based registry of all cerebrovascular events in the district of Udine (153,312 inhabitants), North-Eastern Italy, between April 1, 2007 and March 31, 2009. People with transient ischemic attacks (TIAs) were excluded from this study. Results: In all, 782 cases of stroke (79.28% ischemic, 14.83% hemorrhagic, 3.20% subarachnoid hemorrhage and 2.69% undetermined) were identified. The incidence of ES, LS and PSE was 5.10, 3.14 and 2.22%, respectively. Intracerebral hemorrhage, subarachnoid hemorrhage, stroke of undetermined origin and hyponatremia, represented risk factors for ES (p < 0.05). Among ischemic strokes, ES risk factors were hyponatremia (p = 0.024) and hemorrhagic transformation (p = 0.046). LS risk factors were younger age (p = 0.004) and cortical location of stroke (p = 0.004). Within ischemic strokes, LS risk factors were younger age (p = 0.020) and cortical location (p < 0.0001). Within intracerebral hemorrhages, the only risk factor for LS was the presence of a previous ES (p = 0.017). PSE risk factors were the same as for LS. Conclusions: All acute conditions related to the occurrence of stroke are implicated in the pathogenesis of ES, which becomes a risk factor for LS only in the setting of intracerebral hemorrhages. Therefore, early antiepileptic treatment is needed only in this situation.

Rates of TEM vary primarily depending on study setting, which is concordant with the high degree of heterogeneity of the included records. Forthcoming RCT studies should adopt consistent operational definitions of TEM and broaden the number of moderators, in order to contribute most effectively to the identification of clear-cut sub-phenotypes of BD and patient-tailored pharmacotherapy.

BackgroundThe elderly population and numbers of nursing homes residents are growing at a rapid pace globally. Uncertainty exists regarding the actual rates of major depressive disorder (MDD), bipolar disorder and schizophrenia as previous evidence documenting high rates relies on suboptimal methodology.AimsTo carry out a systematic review and meta-analysis on the prevalence and correlates of MDD, bipolar disorder and schizophrenia spectrum disorder among nursing homes residents without dementia.MethodMajor electronic databases were systematically searched from 1980 to July 2017 for original studies reporting on the prevalence and correlates of MDD among nursing homes residents without dementia. The prevalence of MDD in this population was meta-analysed through random-effects modelling and potential sources of heterogeneity were examined through subgroup/meta-regression analyses.ResultsAcross 32 observational studies encompassing 13 394 nursing homes residents, 2110 people were diagnosed with MDD, resulting in a pooled prevalence rate of 18.9% (95% CI 14.8–23.8). Heterogeneity was high (I2 = 97%, P≤0.001); no evidence of publication bias was observed. Sensitivity analysis indicated the highest rates of MDD among North American residents (25.4%, 95% CI 18–34.5, P≤0.001). Prevalence of either bipolar disorder or schizophrenia spectrum disorder could not be reliably pooled because of the paucity of data.ConclusionsMDD is highly prevalent among nursing homes residents without dementia. Efforts towards prevention, early recognition and management of MDD in this population are warranted.

Differential diagnosis between thrombotic thrombocytopenic purpura (TTP) and other thrombotic microangiopathies (TMA) is usually difficult because of frequently overlapping clinical presentations. Severely depressed ADAMTS13 activity (<10 %) seems distinctive for TTP because of its pathogenetic role. However a long debate exists in the literature about its sensibility and specificity. Our aim was to search for clinical differences between TMA patients referred to our laboratory, comparing them for protease activity <10 versus ≥10 %. ADAMTS13 activity ≥10 % patients (n = 73) showed a higher prevalence of drug- (p = 0.005) and cancer-associated (p < 0.001) TMA. Mean platelet count and renal dysfunction prevalence was lower (p < 0.001), while neurological impairment was more frequent (p = 0.001) in the <10 % ADAMTS13 activity group (n = 109), confirming previous literature findings. When taken neurological manifestations singularly, epilepsy (p = 0.04), focal motor deficit (p < 0.001) and cranial nerve palsy (p = 0.007) were more frequent in the <10 % activity group. In our case series, a <10 % ADAMTS13 activity depicts a group of patients with clinical features similar to TTP patients. Focal motor impairment or epileptic manifestations could further address toward a TTP diagnosis. Studies about treatment efficacy and follow-up are advised to determine whether laboratory findings can guide therapeutic decisions.

Bipolar disorder (BD) is a considerable burden to the affected individual. The need for novel drug targets and improved drug design (DD) in BD is therefore clear. Areas covered: The following article provides a brief, narrative, clinician-oriented overview of the most promising novel pharmacological targets for BD along with a concise overview regarding the general DD process and the unmet needs relevant to BD. Expert opinion: A number of novel potential drug targets have been investigated. With the notable exception of the kynurenine pathway, available evidence is too scarce to highlight a definitive roadmap for forthcoming DD in BD. BD itself may present with different facets, as it is a polymorphic clinical spectrum. Therefore, promoting clinical-case stratification should be based on precision medicine, rather than on novel biological targets. Furthermore, the full release of raw study data to the scientific community and the development of uniform clinical trial standards (including more realistic outcomes) should be promoted to facilitate the DD process in BD.
