Non-avian theropod phalanges from the marine Fox Hills Formation (Maastrichtian), western South Dakota, USA.

We report here the first dinosaur skeletal material described from the marine Fox Hills Formation (Maastrichtian) of western South Dakota. The find consists of two theropod pedal phalanges: one recovered from the middle part of the Fairpoint Member in Meade County, South Dakota; and the other from the Iron Lightning Member in Ziebach County, South Dakota. Comparison with pedal phalanges of other theropods suggests strongly that the Fairpoint specimen is a right pedal phalanx, possibly III-2, from a large ornithomimid.

Characterization and applications of a Crimean-Congo hemorrhagic fever virus nucleoprotein-specific Affimer: Inhibitory effects in viral replication and development of colorimetric diagnostic tests.

Crimean-Congo hemorrhagic fever orthonairovirus (CCHFV) is one of the most widespread medically important arboviruses, causing human infections that result in mortality rates of up to 60%. We describe the selection of a high-affinity small protein (Affimer-NP) that binds specifically to the nucleoprotein (NP) of CCHFV. We demonstrate the interference of Affimer-NP in the RNA-binding function of CCHFV NP using fluorescence anisotropy, and its inhibitory effects on CCHFV gene expression in mammalian cells using a mini-genome system.

Hyalomma rufipes on an untraveled horse: Is this the first evidence of Hyalomma nymphs successfully moulting in the United Kingdom?

During September 2018, a tick was submitted to Public Health England's Tick Surveillance Scheme for identification. The tick was sent from a veterinarian who removed it from a horse in Dorset, England, with no history of overseas travel. The tick was identified as a male Hyalomma rufipes using morphological and molecular methods and then tested for a range of tick-borne pathogens including; Alkhurma virus, Anaplasma, Babesia, Bhanja virus, Crimean-Congo Haemorrhagic fever virus, Rickettsia and Theileria.

Xapuri virus, a novel mammarenavirus: natural reassortment and increased diversity between New World viruses.

Mammarenavirus RNA was detected in Musser's bristly mouse (Neacomys musseri) from the Amazon region, and this detection indicated that rodents were infected with a novel mammarenavirus, with the proposed name Xapuri virus (XAPV), which is phylogenetically related to New World Clade B and Clade C viruses. XAPV may represent the first natural reassortment of the Arenaviridae family and a new unrecognized clade within the Tacaribe serocomplex group.

The Development of a Novel Diagnostic Assay That Utilizes a Pseudotyped Vesicular Stomatitis Virus for the Detection of Neutralizing Activity against Crimean-Congo Hemorrhagic Fever Virus.

Crimean-Congo hemorrhagic fever virus is a risk group 4 pathogen, which mandates the use of maximum containment facilities, often termed biosafety level 4 or containment level 4 when working with infectious materials. Diagnostic and research work involving live viruses in such laboratories is time-consuming and inconvenient, resulting in delays. Herein, we show that serum neutralizing activity against the virus can be measured in low-containment laboratories using a pseudotyped virus.

Treatment of a Mandibular Glandular Odontogenic Cyst with Peripheral Ostectomy, Bone Allograft, and Implant Reconstruction: A Case Report.

This article reports on a case of a glandular odontogenic cyst (GOC) in the posterior mandible of a 25-year-old male treated with peripheral ostectomy, bone allograft, and an implant-supported fixed dental prosthesis. During a routine 3-month postoperative visit, a radiograph suggested vertical bone loss on the implant in the location of the mandibular right first molar. The three-walled defect was surgically treated with debridement, bone allograft, and a membrane.

Malpractice, Criminality, and Medical Regulation: Reforming the Role of the GMC in Fitness to Practise Panels.

A recent Law Commission Review emphasised that medical fitness to practise panels (also called medical practitioners tribunals) are an important legal mechanism for ensuring that public trust in medical regulation is maintained when a complaint is made against a doctor. This article examines trends over time in panel outcomes to identify their effectiveness in ensuring public protection. Although a rise in complaints, and a change from the criminal to civil standard of proof, has not led to more doctors being struck off the medical register, increasingly action is being taken to provide advice, issue warnings, and agree rehabilitative forms of action with doctors.

Function of calcium phosphate renal concrements in extant Nautilus: a paradigm for Cambrian-relict short-term mineral reserve equivalent to vertebrate bone.

Renal uroliths (concrements) of calcium phosphate have long been known to exist in both growing and mature (non-growing) Nautilus specimens, but to date no evidence-based explanation for their existence has been available. The currently favored speculation is that they function as a calcium reserve for shell and septal calcification. Here we present new observational and experimental data that are consistent with the hypothesis that they serve as a mineral/ion reserve, allowing short-term (<1 day) addition of ionized calcium and phosphorus to blood and other body fluids, in a way analogous to that of vertebrate bone.

Rapid molecular detection of Lujo virus RNA.

Lujo virus is an emerging arenavirus circulating in Southern Africa. Although to date there has only been a single outbreak of the novel haemorrhagic disease resulting from human infection with this virus, the case-fatality rate of exposed individuals, including nosocomial transmission, was 80%. The ability to identify viral haemorrhagic fevers accurately, especially those capable of nosocomial transmission, is of critical importance.

Identification and analysis of Crimean-Congo hemorrhagic fever virus from human sera in Tajikistan.

Background: Crimean-Congo hemorrhagic fever (CCHF) is a virulent tick-borne disease reported in more than 30 countries across Europe, Africa, and Asia. The disease is considered endemic in several Central Asian countries, including Tajikistan; however reports of human cases from these regions rarely reach the West.

Methods: We analyzed all historical confirmed cases of CCHF in Tajikistan, mapping these reports against geographic data to assess risk areas.

Genome Sequence of Ex-Afghanistan Crimean-Congo Hemorrhagic Fever Virus SCT Strain, from an Imported United Kingdom Case in October 2012.

Crimean-Congo hemorrhagic fever (CCHF) virus is a serious human pathogen causing severe hemorrhagic disease with a fatality rate of up to approximately 30%. We have determined the viral genomic sequence from an isolate that caused a fatal case of imported CCHF in the United Kingdom in October 2012.

Development of a real-time RT-PCR assay for the detection of Crimean-Congo hemorrhagic fever virus.

Crimean-Congo hemorrhagic fever (CCHF) is a virulent tick-borne disease with a case fatality rate ranging from 10-50% for tick-borne transmission, and up to 80% for nosocomial transmission. Human cases have been reported in over 30 countries across Europe, Asia, and Africa. It appears to be spreading to new areas with several countries reporting their first human cases of CCHF disease within the past 10 years.

Hazara virus infection is lethal for adult type I interferon receptor-knockout mice and may act as a surrogate for infection with the human-pathogenic Crimean-Congo hemorrhagic fever virus.

Hazara virus (HAZV) is closely related to the Crimean-Congo hemorrhagic fever virus (CCHFV). HAZV has not been reported to cause human disease; work with infectious material can be carried out at containment level (CL)-2. By contrast, CCHFV causes a haemorrhagic fever in humans and requires CL-4 facilities.

Correlates and trends in training satisfaction on completion of internal medicine-pediatrics residency: a 5-year study.

Objective: To examine trends in training satisfaction in graduates of combined internal medicine-pediatrics (Med-Peds) training programs and whether curricular elements designed to enhance the integration of the two disciplines have been successful.

Study Design: We conducted a cross-sectional survey of all graduating Med-Peds residents (years 2003-2007). Responses across survey years were analyzed to identify trends.

Graduating med-peds residents' interest in part-time employment.

Objective: As part-time work is becoming more popular among the primary care specialties, we examined the demographic descriptors of med-peds residents seeking and finding part-time employment upon completion of residency training.

Methods: As part of the 2006 annual American Academy of Pediatrics (AAP) Graduating Med-Peds Residents Survey, we surveyed the graduating residents of all med-peds programs about their interest in and plans for part-time employment. A total of 199 (60%) of the residents responded.

The effect of dual training in internal medicine and pediatrics on the career path and job search experience of pediatric graduates.

Objective: To compare the job search experience and career plans of medicine-pediatrics (med-peds) and pediatric residents.

Study Design: Annual surveys of graduating med-peds and pediatric residents were compared from 2003 and 2004.

Results: The survey response rates were 58% for med-peds residents (n = 427) and 61% for pediatric residents (n = 611).

Molecular diagnosis and analysis of Chikungunya virus.

Background: In March 2005 a Chikungunya fever outbreak began on the islands of the Indian Ocean. The number of cases of this disease dramatically rose amongst these islands before affecting over a million people in India. Travellers to these regions have returned to the UK with the disease leading to a greater than 15-fold increase in the annual number of Chikungunya virus (CHIKV) sero-positive samples in 2006.
