BACKGROUND: Treatment-resistant schizophrenia (TRS) is a condition characterized by intense symptom severity and poor response to different antipsychotic agents. The first therapeutic option in TRS is clozapine, but often high/medium doses are not tolerated. Adding an oral antipsychotic to low doses of clozapine is a promising strategy in the management of TRS. On the contrary, there are few data on combined clozapine/long-acting injectable (LAI) medications, and none on clozapine/LAI-aripiprazole...

BACKGROUND: The studies reported here were conducted to assess the efficacy of ivermectin long-acting injection (IVM LAI; IVOMEC® GOLD, Merial; 3.15 % w/v ivermectin) for the treatment and control of natural infestations of cattle by Hypoderma bovis and Hypoderma lineatum, which are the most economically important oestrid flies of cattle in the northern hemisphere. METHODS: Cattle selected from herds with a history of Hypoderma infestation were grouped into blocks of three (Italy, 33 cattle; Germany, 30 cattle) or two (USA, 16 cattle) animals each, on the basis of positivity at the pre-treatment anti-Hypoderma antibody titres...

AIM: To determine if there was a benefit from treating ewes with a low body condition score (BCS) with long acting anthelmintic products pre-lambing and to compare the effects of two commonly used treatment options. METHODS: The study was conducted on a single commercial hill country sheep and beef property in the central North Island of New Zealand. Mixed age twin-bearing ewes were preselected by the farmer as being in poor condition 4 weeks before the planned start of lambing, and were sequentially drafted into three equal groups identified with coloured ear tags...

BACKGROUND: Post-abortion contraceptive use in India is low and the use of modern methods of contraception is rare, especially in rural areas. This study primarily compares contraceptive use among women whose abortion outcome was assessed in-clinic with women who assessed their abortion outcome at home, in a low-resource, primary health care setting. Moreover, it investigates how background characteristics and abortion service provision influences contraceptive use post-abortion. METHODS: A randomized controlled, non-inferiority, trial (RCT) compared clinic follow-up with home-assessment of abortion outcome at 2 weeks post-abortion...

Our aim was to determine factors relating to continuation with treatment with paliperidone palmitate long-acting injection (PP) in a 2 year, non-interventional, observational study of the use of PP in consecutive patients treated in a secondary care environment. We followed-up 300 consecutive patients; 24 (8%) were lost to follow-up (7 deceased and 17 left the care of the trust). Overall, 107 patients of the remaining 276 who were not lost to follow-up (38.7%) completed 2 years' continuous treatment. A further 21 (7...

BACKGROUND: Risperidone long-acting injection (RLAI) is increasingly being switched to paliperidone palmitate (PP) because of several benefits. However, this switching is not always successful. METHODS: We examined patient profiles following discontinuation of PP after switching from RLAI. We collected the electronic records of 24 patients with schizophrenia who had switched from RLAI to PP treatment at our hospital between November 2013 and March 2014. Twelve patients continued PP injection for over 1 year (PP-continuers), the other 12 patients discontinued within 1 year (PP-discontinuers), and both groups were followed up until December 31, 2014...

Long-acting injectable antipsychotics (LAIs) are among the most effective treatments in psychiatry, yet they remain underutilized in clinical practice. Although LAIs are typically used to maintain treatment adherence in patients with chronic schizophrenia, recent research has suggested that they may also provide an effective treatment strategy for patients with early-phase or first-episode disease. In October 2015, a group of 8 experts on the management of schizophrenia and LAIs met to evaluate the evidence surrounding the efficacy, safety, and cost-effectiveness of LAIs and to develop practical recommendations regarding the clinical use, education, and unmet needs related to LAIs...

: Acromegaly is a human disease of growth hormone (GH) excess with considerable morbidity and increased mortality. Somatostatin analogues are first line medical treatment but the disease remains uncontrolled in up to 40% of patients. GH receptor (GHR) antagonist therapy is more effective but requires frequent high-dose injections. We have developed an alternative technology for generating a long acting potent GHR antagonist through translational fusion of a mutated GH linked to GH binding protein and tested three candidate molecules...

BACKGROUND: Drug-paired environments can act as stimuli that elicit drug craving. In humans, drug craving is influenced by the amount of time abstinent, number of past periods of abstinence, and inadvertent exposure to the previously abused drug. The current experiments were designed to determine the effects of (a) the duration of abstinence on expression of EtOH-seeking; (b) EtOH priming following a short and long abstinence period; and (c) repeated deprivation cycles on relapse drinking and EtOH-seeking...

Hyaluronic Acid (HA)-based dermal formulations have rapidly gained a large consensus in aesthetic medicine and dermatology. HA, highly expressed in the Extracellular Matrix (ECM), acts as an activator of biological cascades, stimulating cell migration and proliferation, and operating as a regulator of the skin immune surveillance, through specific interactions with its receptors. HA may be used in topical formulations, as dermal inducer, for wound healing. Moreover, intradermal HA formulations (injectable HA) provide an attractive tool to counteract skin aging (e...

Basal insulin peglispro (BIL) is a novel basal insulin with a flat, prolonged activity profile. BIL has been demonstrated in a dog model, in healthy men and in patients with type 1 diabetes (T1D) to have significant hepato-preferential action resulting from reduced peripheral activity. In the IMAGINE-Phase 3 clinical trial program, more than 6000 patients were included, of whom ~3900 received BIL. Of the 7 pivotal IMAGINE trials, 3 studies were double-blinded and 3 were in T1D patients. BIL consistently demonstrated a greater HbA1c reduction, less glycaemic variability and a clinically relevant reduction in the rates of nocturnal hypoglycaemia across comparator [glargine and isophane insulin (NPH)] studies...

OBJECTIVES: Olanzapine is a well established treatment for schizophrenia. The olanzapine pamoate depot (long-acting injectable) formulation improves compliance and clinical trials have shown it to be effective. However, there are no previously published reports evaluating olanzapine depot in violent patients with schizophrenia in the community. We evaluated the clinical efficacy of olanzapine depot, its effect on violence, hospitalization and incarceration in community patients with schizophrenia and prior history of serious violence...

Younger patients with schizophrenia have most likely experienced fewer adverse consequences of the illness than older patients who may have experienced a lifetime of treatment as well as socio-economic problems as a consequence of the illness. There is limited information regarding differential efficacy of long-acting injectable (LAI) antipsychotic medications across the age span in patients with schizophrenia. We conducted a post hoc age and gender analysis of treatment response to aripiprazole lauroxil (AL; ARISTADA®; Alkermes, Inc...

Background.  A long-acting injectable formulation of rilpivirine (RPV), under investigation as antiretroviral pre-exposure prophylaxis (PrEP), may facilitate PrEP adherence. In contrast, cross-resistance between RPV and nonnucleoside reverse-transcriptase inhibitors comprising first-line antiretroviral therapy (ART) could promote human immunodeficiency virus (HIV) drug resistance and reduce PrEP's effectiveness. Methods.  We use novel mathematical modeling of different RPV PrEP scale-up strategies in KwaZulu-Natal, South Africa, to investigate their effects on HIV prevention and drug resistance, compared with a reference scenario without PrEP...

Caterpillar hairs are thought to act as a physical barrier against natural enemies, including parasitoids. However, very few studies have experimentally demonstrated how hairs protect caterpillars from parasitoid oviposition. To clarify the importance of caterpillar hairs as an anti-parasitoid defence, we observed the generalist endoparasitoid Meteorus pulchricornis (Hymenoptera: Braconidae) attacking both smooth and hairy caterpillars under laboratory conditions. A female Meteorus pulchricornis uses its ovipositor to inject venom and lay a single egg inside host larvae...

Here we describe development of a silicone rubber/stainless steel mesh cage implant system, much like that used to assess biocompatibility of biomaterials [1], for easy removal of injectable polymer microspheres in vivo. The sterile cage has a type 316 stainless steel mesh size (38 μm) large enough for cell penetration and free fluid flow in vivo but small enough for microsphere retention, and a silicone rubber shell for injection of the microspheres. Two model drugs, the poorly soluble steroid, triamcinolone acetonide, and the highly water-soluble luteinizing hormone-releasing hormone (LHRH) peptide superagonist, leuprolide, were encapsulated in PLGA microspheres large enough (63-90 μm) to be restrained by the cage implant in vivo...
