CONTEXT No large-scale posttraumatic stress disorder drug trials have been conducted to evaluate treatment effects beyond 12 weeks outside of those with selective serotonin reuptake inhibitors. OBJECTIVE To evaluate the efficacy of venlafaxine extended release (ER), a serotonin norepinephrine reuptake inhibitor, in posttraumatic stress disorder. DESIGN(More)
INTRODUCTION Loss to follow-up is a major challenge in the prevention of mother to child transmission of HIV (PMTCT) programme in Malawi with reported loss to follow-up of greater than 70%. Tingathe-PMTCT is a pilot intervention that utilizes dedicated community health workers (CHWs) to create a complete continuum of care within the PMTCT cascade, improving(More)
OBJECTIVES To test the long-term efficacy and safety of venlafaxine extended-release (ER) in preventing recurrence in patients with major depression. METHOD This multiple-phase study, entitled "Prevention of Recurrent Episodes of Depression With Venlafaxine for Two Years" (PREVENT), was conducted from December 2000 through July 2005 in patients with(More)
Weight gain is an important issue in the use of atypical antipsychotics, including olanzapine. A retrospective analysis of patterns of weight gain and possible covariates was performed for 1191 patients diagnosed with schizophrenia or schizoaffective disorder who were treated with olanzapine for up to 52 weeks. Patients were dichotomized into 2 main groups(More)
Energy deficit after traumatic brain injury (TBI) may alter ionic homeostasis, neurotransmission, biosynthesis, and cellular transport. Using an in vitro model for TBI, we tested the hypothesis that stretch-induced injury alters mitochondrial membrane potential (delta(psi)m) and ATP in astrocytes and neurons. Astrocytes, pure neuronal cultures, and mixed(More)
BACKGROUND Takotsubo cardiomyopathy (TC) or transient left ventricular apical ballooning syndrome is an acute cardiac syndrome characterized by transient wall motion abnormalities extending beyond a single epicardial vessel in the absence of significant obstructive coronary artery disease. AIM This study was to describe the clinical characteristics of TC(More)
The family of 5 muscarinic acetylcholine receptors belongs to the superfamily of G protein coupled neurotransmitter receptors that serve in part as regulators of synaptic function. Muscarinic receptors are anatomically positioned in cortical and subcortical areas and modulate dopaminergic and glutamatergic neurotransmission thought to be dysfunctional in(More)
OBJECTIVE In 2011, Malawi implemented Option B+ (B+), lifelong antiretroviral therapy (ART) for pregnant and breastfeeding women. We aimed to describe changes in service uptake and outcomes along the antenatal prevention of mother-to-child transmission (PMTCT) cascade post-B+ implementation. DESIGN Pre/post study using routinely collected program data(More)
BACKGROUND The Tingathe program utilizes community health workers to improve prevention of mother-to-child transmission (PMTCT) service delivery. We evaluated the impact of antiretroviral (ARV) regimen and maternal CD4+ count on HIV transmission within the Tingathe program in Lilongwe, Malawi. METHODS We reviewed clinical records of 1088 mother-infant(More)
