BACKGROUND: The use of long-acting injectable antipsychotics in recently diagnosed schizophrenia remains less explored. We evaluated the efficacy and safety of paliperidone palmitate once-monthly (PP1M) treatment in adult patients with recently diagnosed vs. chronic schizophrenia. RESEARCH DESIGN AND METHODS: These post-hoc analyses included two multicenter studies. Study 1 (NCT01527305) enrolled recently diagnosed (≤5 years) and chronic (>5 years) patients; Study 2 (NCT01051531) enrolled recently diagnosed patients only...

The aim was to evaluate the tadalafil-mediated effects at molecular level on bone marrow-derived mesenchymal stem cells (MSCs) survival and their homing into the infarcted hearts to promote cardiac repair and improve function. MSCs were pretreated in vitro with inhibitors of PKG, MAPK, FasL, nitric oxide synthase (NOS) (L-NAME), CXCR4 (AMD3100), or miR-21 inhibitors (+/-luciferase construction +/-Fas) prior to tadalafil treatment for 2 h. These MSCs were then subjected to H2O2 stress to assess their injury...

In animal studies, intravenous continuous infusion or peritoneal injection of sphingosine-1-phosphate (S1P) has been shown to decrease chemotherapy- and radiotherapy-induced apoptosis on primordial follicles. Although a long-acting oral form of an S1P analogue (FTY720, fingolimod) has been recently developed and utilized in women with multiple sclerosis, there are no data exploring its ability to avoid spontaneous follicle apoptosis. Thirty 10-month-old female rats were randomly assigned to 3 groups to investigate whether fingolimod would be able to decrease the spontaneous ovarian follicle apoptosis ratio...

PIVET recombinant FSH (rFSH) dosing algorithms have been designed for rFSH injection pens, providing optimal pregnancy and live birth productivity rates whilst minimizing risk and occurrence of ovarian hyperstimulation syndrome (OHSS). Recently, long-acting recombinant gonadotrophin corifollitropin (Elonva) was approved for use in assisted reproduction, and welcomed by patients as the single injection allowed ovarian stimulation over 7 days without need for multiple injections. Consequently, another rFSH dosing algorithm was devised to incorporate Elonva, and these cycles were compared to standard rFSH agents, Gonal-f and Puregon...

BACKGROUND: There are some ongoing debates on the potential link between testosterone therapy (TT) and risk of acute myocardial infarction (MI). AIM: To investigate the association between acute MI and TT use compared with non-use in men having documented hypogonadism (diagnostic International Classification of Diseases, Ninth Revision codes 257.2, 257.8, 257.9, 758.7) in patient claims records. METHODS: This retrospective cohort study used a real-world US-based administrative health care claims database (MarketScan 2004-2013; Truven Health Analytics, Ann Arbor, MI, USA) to compare MI rates between TT-treated men and a cohort of untreated hypogonadal men matched by a calendar time-specific propensity score...

Drug-loaded polymeric microparticles have been used as long-acting injectable (LAI) depot formulations. To obtain FDA approval, a generic LAI depot product needs to be qualitatively (Q1) and quantitatively (Q2) the same in terms of inactive ingredients as its reference listed drug (RLD). However, Q1/Q2 sameness as the RLD does not guarantee the same in vitro drug release profile and in vivo performance, especially when the manufacturing methods are different. There is little consensus on how the in vitro testing needs to be done to examine the release profiles of LAI depot formulations...

Bupivacaine is a long-acting local anesthetic (LA) used for cutaneous infiltration, peripheral nerve blocks, epidural and spinal anesthesia. However, its application may result in cardiovascular complications such as: hypotension, bradycardia, cardiac arrest and toxic myocardial injury. The authors describe a 53-year-old male with a history of cigarette smoking, admitted for an elective inguinal hernia surgery. Before surgery, the patient received subarachnoid injection of bupivacaine (20 mg). After the operation, he developed transient hypotension...

In the auditory cortex (AC), corticofugal projections arise from each level of the auditory system and are considered to provide feedback "loops" important to modulate the flow of ascending information. It is well established that the cortex can influence the response of neurons in the superior colliculus (SC) via descending corticofugal projections. However, little is known about the relative contribution of different pyramidal neurons to these projections in the SC. We addressed this question by taking advantage of anterograde and retrograde neuronal tracing to directly examine the laminar distribution, long-range projections, and electrophysiological properties of pyramidal neurons projecting from the AC to the SC of the mouse brain...

Long-acting drug nanosuspension formulations are coming to the fore as controlled release strategies for several medical conditions and as a preventative measure against HIV infection. However, such delivery systems must, by necessity, be given by hypodermic injection, typically into muscle. This poses problems for patients who are needle-phobic, given that injections have to be administered on a weekly or monthly basis. Needle-stick injuries, inappropriate reuse of needles, and poor disposal practices are major challenges in developing countries...

B Duncan X Lascelles, Kristin Kirkby Shaw
One of the most effective means of preventing the transduction and transmission of acute and perioperative pain is through the use of local anaesthetics. However, local anaesthetics currently available have a relatively short duration of action. Although there are several tools available to treat perioperative pain in companion animals, overall, there is an unmet need for products that can be administered in the clinic, and provide pain relief for the crucial first few days following surgery in the home environment...

During the past 30 years of antiretroviral therapy, continuous improvements in drug discovery have provided increasingly potent and safer antivirals that have transformed HIV infection in a chronic illness, rarely fatal. Non-nucleoside reverse-transcriptase inhibitors (NNRTIs) are frequently used as part of any antiretroviral combination therapy. Side effects and low resistance barrier of fi rst-generation NNRTIs (e.g., nevirapine and efavirenz) have been overcome with rilpivirine (RPV), and the last NNRTI approved for the treatment of HIV infection...
