Background: Electroconvulsive Therapy (ECT) has been widely applied to treat schizophrenia (SCZ) in the presence of resistance to pharmacotherapy. The mechanism of action of ECT in schizophrenia has not been fully clarified, though its intrinsic mechanism presents analogies with some neurobiological processes mediated by nerve growth factor (NGF).

Objectives: The aim of this study was to investigate in patients with treatment-resistant schizophrenia (TRS) the effect of ECT on acute and long-term NGF serum levels and the association with the clinical outcomes.

Brain damage of various aetiologies can lead to different disorders of consciousness (DOC), varying from coma to vegetative, to minimally conscious states. Each state is characterised by a different degree of wakefulness, awareness, pain sensitivity and is differentially handled with respect to treatment, ethical considerations and end-oflife decisions. Thus, its correct identification is crucial while devising or modulating appropriate treatment strategies.

What Is Known And Objective: The prescription of potentially inappropriate medications (PIMs) for older adults is a well-known population health concern. Updated country-specific estimates of inappropriate prescribing in older adults using germane explicit criteria are needed to facilitate physician-tailored quality improvement strategies. Therefore, we sought to determine the prevalence of PIMs for older adults in Emilia-Romagna, Italy, using the updated Maio criteria.

Seizure threshold (ST) is a parameter that differs in each person and can be modified both spontaneously and because of drug intake and/or other exogenous factors. A rise in ST during a course of electroconvulsive therapy (ECT) has been demonstrated in patients with depression and mania, but little information has been available as to whether the same result occurs in schizophrenia (SCZ). 11 male patients underwent estimation of the seizure threshold over a bilateral ECT course.

The objective of this study was to examine whether levels of endotoxin and other markers of immuno-inflammatory activation are altered in adult patients with severe autism. We determined circulating serum endotoxin levels, its soluble receptor (sCD14), and markers of immuno-inflammatory activation (IL-1beta, IL-6, and IL-10) in 22 adult patients with severe autism and 28 age- and gender-matched healthy controls. Compared with healthy subjects, serum levels of endotoxin were significantly higher in autistic patients and inversely and independently correlated with Socialization scores on the Vineland Adaptive Behavior Scales (VABS) and ADI-R Domain A score (social).

To determine whether a higher dosage of interferon (IFN) and/or a prolonged time of administration may improve the efficacy of combination therapy, we conducted a 4-arm randomized trial on patients with chronic hepatitis C relapsing after 1 or more previous treatment courses with IFN monotherapy. Group A (n = 70) received 3 MU IFN alfa-2b 3 times per week plus ribavirin 1,000 mg/d for 12 months; group B (n = 70) received 5 MU 3 times per week plus ribavirin for 12 months; group C (n = 82) received 3 MU 3 times per week plus ribavirin for 6 months, and group D (n = 73) received 5 MU 3 times per week plus ribavirin for 6 months. The primary end point was the clearance of viremia at the end of 6-month follow-up: test results for hepatitis C virus (HCV)-RNA were negative in 54% of group A, 56% of group B, 40% of group C, and 49% of group D patients (P = NS).

Current evidence suggests that aberrant crypt foci (ACF) can be used to evaluate agents for their potential colon carcinogenic activity. The aim of the present study was to determine whether senna pod extract (SE) itself induces ACF and tumors in the rat colon or increases the development of ACF and tumors induced by azoxymethane (AOM). A daily administration of SE 10 mg/kg by mouth for 13-28 weeks produced a weak laxative effect but did not itself cause the appearance of ACF or tumors.
