BACKGROUND: Inotuzumab ozogamicin, an anti-CD22 monoclonal antibody bound to a toxin, calicheamicin, has shown single-agent activity in relapsed or refractory acute lymphoblastic leukaemia. We aimed to assess the activity and safety of inotuzumab ozogamicin in combination with low-intensity chemotherapy in older patients with acute lymphoblastic leukaemia. METHODS: We did a single-arm, phase 2 study at the MD Anderson Cancer Center (Houston, TX, USA). Eligible patients were aged 60 years or older and had newly diagnosed, Philadelphia chromosome-negative, acute lymphoblastic leukaemia, and an Eastern Cooperative Oncology Group performance status of 3 or lower...

AIM: The abdominal incision for specimen extraction could trigger postoperative pain after laparoscopic colorectal resections (LCR). Continuous Wound Infusion (CWI) of ropivacaine may be a valuable option for postoperative analgesia. This study was undertaken to evaluate the potential benefits of ropivacaine CWI on pain relief, metabolic stress reaction, prevention of wound hyperalgesia and residual incisional pain after LCR. A subgroup with intravenous lidocaine infusion (IVL) was added to discriminate between the peripheral and systemic effects of local anaesthetic infusions...

This study's objective was to determine if nutrient restriction during late gestation affected beef heifer feed intake, body weight (BW) gain and endocrine regulation during a 10-week feeding trial. During the last 100 days of gestation, control (CON) dams were fed to increase body condition score (BCS). Whereas, nutrient-restricted dams (NR) and NR dams protein supplemented 3 days/week (NRS) were fed to decrease BCS by 1.2. After parturition, all cow-calf pairs were moved to a common pasture and fed in excess of requirements until weaning...

PURPOSE: Vibration therapy has been shown to improve fracture healing. In this study, we investigated the effects of continuous or different intermittent vibration regimens on fracture healing in sheep models on the basis of radiographs, mechanical, and biochemical testing. METHODS: The 63 right-hind metatarsals from 63 sheep (12-month-old) were osteotomized; followed by surgical fixation with a steel plate. Two weeks after the surgery, the sheep with right-hind metatarsal fractures were randomly divided into seven groups (n=9/group): control (no vibration treated), continuous vibration (CV), one, three, five, seven and 14-day intermittent vibration (named IV-1, -3, -5, -7, and -14, respectively) groups, which represented a cycle of the successive n-day vibration and successive n-day break...

Since the introduction of intravenous drug self-administration methodology over 50 years ago, experimental investigation of addictive behaviour has delivered an enormous body of data on the neural, psychological and molecular mechanisms of drug reward and reinforcement and the neuroadaptations to chronic use. Whether or not these behavioural and molecular studies are viewed as modelling the underpinnings of addiction in humans, the discussion presented here highlights two areas-the impact of drug-associated conditioned stimuli-or drug cues-on drug seeking and relapse, and compulsive cocaine seeking...

Seizures constitute a determining aspect in quality of life and are frequently challenging in palliative care-a field where treatment has yet to be standardised. Levetiracetam-a new generation anticonvulsant-has proved efficacy both through oral, as well as intravenous administration in the general population. This case reports on the use of continuous subcutaneous levetiracetam to effectively control seizures in a terminally ill patient without patent oral route.

BACKGROUND: Despite, Sri Lanka lies in the melioidosis endemic belt between 5°N and 10°N surrounded by countries known to have endemic melioidosis for many years, comparatively fewer cases of melioidosis infection have been reported in Sri Lanka. Melioidosis has a wide spectrum of clinical presentation, ranging from severe pneumonia to abscess formation in various organs. Isolated septic arthritis, which is a rare but well-recognized manifestation of melioidosis, could be the sole presenting problem in some patients with melioidosis...

BACKGROUND: Colorectal surgery is frequently complicated by surgical site infections (SSIs). The most important consequences of SSIs are prolonged hospitalization, an increased risk of surgical reintervention and an increase in mortality. Perioperative intravenously administered antibiotic prophylaxis is the standard of care to reduce the risk of SSIs. In the last few decades, preoperative orally administered antibiotics have been suggested as additional prophylaxis to further reduce the risk of infection, but are currently not part of routine practice in most hospitals...

BACKGROUND: For patients unable to receive heparin anticoagulation during haemodialysis, saline flushes to reduce circuit clotting are often the norm. Regional citrate anticoagulation (RCA) although effective is not used by many centres including in Singapore. We wanted to demonstrate the superiority and safety of a simple regional citrate anticoagulation regime, compared to saline flushes, for heparin-free low flux haemodialysis. METHODS: This is a prospective, open label, cross over study on 25 sequential haemodialysis sessions for inpatients receiving heparin-free haemodialysis...

BACKGROUND:  The increasing prevalence of intravenous drug users (IVDU) has resulted in higher incidence of right-sided infective endocarditis (RSIE). However, treatment guidelines for RSIE in IVDU are not well defined. The aim is to evaluate efficacy of different treatment strategies in reducing mortality and to describe treatment outcomes. METHODS:  We systematically reviewed the literature using PubMed, Cochrane, CENTRAL, OvidEMBASE, Web of Science, and Medline databases to include prospective studies that compare mortality rates among IVDU with RSIE receiving isolated medical treatment versus those receiving medical-surgical treatment...

Atypical antipsychotic drugs have been associated with the development of obesity and diabetes. In particular, olanzapine can induce peripheral insulin resistance and compensatory hyperinsulinemia independent of weight gain or psychiatric disease. To determine if this compensatory increase in insulin is mediated by parasympathetic muscarinic stimulation, we randomized fifteen healthy subjects 2:1 to receive double-blind olanzapine or placebo for 9 days under diet and activity controlled inpatient conditions...

To establish whether incretin hormones affect insulin clearance, the aim of this study was to assess insulin clearance in mice with genetic deletion of receptors for both glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), so called double incretin receptor knockout mice (DIRKO). DIRKO (n=31) and wild-type (WT) C57BL6J mice (n=45) were intravenously injected with D-glucose (0.35 g/kg). Blood was sampled for 50 minutes and assayed for glucose, insulin and C-peptide. Data were modeled to calculate insulin clearance; C-peptide kinetics was established after human C-peptide injection...

Sickle cell disease (SCD) manifests itself with vaso-occlusive episodes leading to infarction. Placement of intravascular catheters provides a useful route for management of pain crises as well as other complications. However, catheter misuse is a commonly unrecognized problem, which can have lethal consequences. We present a case of fatal splenic sequestration/hyperhemolysis secondary to foreign body pulmonary and systemic embolization due to intravenous administration of hydromorphone pills in a young woman with SCD...

The downregulation of β-adrenergic receptors (β-AR) and decreased cAMP-dependent protein kinase activity in failing hearts results in decreased phosphorylation and inactivation of phosphatase-inhibitor-1 (I-1), a distal amplifier element of β-adrenergic signaling, leading to increased protein phosphatase 1 activity and dephosphorylation of key phosphoproteins, including phospholamban. Downregulated and hypophosphorylated I-1 likely contributes to β-AR desensitization; therefore its modulation is a promising approach in heart failure treatment...

Abciximab is a glycoprotein IIb/IIIa receptor antagonist that functions to prevent platelet aggregation, thus reducing thrombus initiation and propagation. It has been widely used during percutaneous endovascular interventions, such as aneurysm coil embolization, angioplasty, atherectomy, and stent placement, as both a preventative and a salvage therapy. The use of abciximab in cardiac and neurosurgical procedures has been associated with a reduced incidence of ischemic complications and a decreased need for repeated intervention...

PURPOSE: Therapeutic options for patients with malignant pheochromocytoma are currently limited, and therefore new treatment approaches are being sought. Targeted radionuclide therapy provides tumor-specific systemic treatments. The β-emitting radiopharmaceutical meta-131I-iodo-benzylguanidine (131I-MIBG) provides limited survival benefits and has adverse effects. A new generation of radionuclides for therapy using α-particles including meta-211At-astato-benzylguanidine (211At-MABG) are expected to have strong therapeutic effects with minimal side effects...
