In clinical practice, the finding of an elevated mean corpuscular volume (MCV), macrocytic anaemia or specific neurological symptoms is often the reason to test for vitamin B12 (B12) deficiency. Use of the MCV as a test for the detection or exclusion of B12 deficiency is only justified if the diagnostic accuracy is sufficiently high. However, the sensitivity and specificity are not well known. ...

Responding to regional advancements in combating measles, the World Health Organization in May 2008 called for an assessment of the feasibility of measles eradication, including whether sufficient vaccine supply exists. Interviews with international health officials and vaccine-makers provided data for a detailed model of worldwide demand and supply for measles-containing vaccine (MCV). The stu...

Merkel cell polyomavirus (MCV) is the etiological agent of Merkel cell carcinoma (MCC), a rare and highly lethal human skin cancer. A natural component of skin flora, MCV becomes tumorigenic only after integration into the host DNA together with specific mutations to the viral genome. Research on MCV large T (LT) and small T (sT) antigens, the only viral products expressed in MCC, shows that th...

OBJECTIVES To assess whether mean corpuscular volume (MCV) is useful in detecting non-adherence to AZTcontaining therapy. DESIGN Observational study within randomised controlled trial. METHODS We combined data from two treatment arms in SPARTAC, an RCT of short-course cART in primary HIV infection, classifying participants as responders (HIV-RNA decrease ≥1 log(10) or reaching <400copies/ml...

OBJECTIVE To compare the defibrillation efficacy of a novel lead system placed in the middle cardiac vein with a conventional non-thoracotomy lead system. METHODS In eight pigs (weighing 35-71 kg), an electrode was advanced transvenously to the right ventricular apex (RV), with the proximal electrode in the superior caval vein (SCV). Middle cardiac vein (MCV) angiography was used to delineate...

OBJECTIVE To describe missed opportunities for meningococcal (MCV); tetanus, diphtheria, acellular pertussis (Tdap); and human papillomavirus (HPV) vaccination among adolescents. METHODS Retrospective electronic health record data review of adolescents aged 11-18 years at the time of their visit to a university-based pediatric practice in Seattle from 2006 to 2011. The primary outcome was mis...

AIMS To look for changes in nerve conduction velocity (NCV) in early stages of glucose intolerance, i.e. in impaired glucose tolerance (IGT) and in asymptomatic newly diagnosed Type 2 diabetic subjects (NDD). MATERIALS AND METHODS A total of 225 subjects were categorized as: Group 1: Subjects with normal glucose tolerance (NGT), Group 2: IGT subjects and Group 3: NDD subjects. Motor (MCV) and...

Thirty-four blood samples of neonates in Dubai, UAE, with an MCV below 90 fL were checked by high performance liquid chromatography (HPLC) for hemoglobin variants to confirm a previous study carried out in Western Province of Saudi Arabia which showed a very high predictive index of such MCV for alpha (α-) thalassemia minor (ATM). MCH below 30 pg was an additional factor which supported such a ...

Minimum cost variance control (MCV) optimizes the variance of the cost function while the cost mean is kept at a prespecified level. The solutions of the infinite time horizon full-state-feedback MCV problem are found using the Hamilton-Jacobi theory. In the solutions of infinite time horizon MCV control problem, a pair of coupled algebraic Riccati equations arises. This paper considers the exi...

INTRODUCTION Charcot-Marie-Tooth disease (CMT) is the most frequent form of inherited neuropathy. In accordance with the inheritance pattern and degree of slowing of motor conduction velocity (MCV) of the median nerve, CMT encompasses five main forms: CMT1 (autosomal dominant [AD] or X-linked transmission and MCV < 38 m/s); CMT2 (AD or X-linked transmission and MCV > 38 m/s); CMT4 (autosomal re...
