The 'onion skin' sign of a low-grade appendiceal mucinous neoplasm: An incidental finding during early pregnancy assessment.

A low-grade appendiceal mucinous neoplasm (LAMN) is a cystic dilatation of the appendix resulting from the accumulation of mucinous secretions caused by a luminal obstruction. Although usually benign, pseudomyxoma peritonei may occur in the event of rupture, and 10% of cases may be secondary to appendiceal cystadenocarcinoma. A LAMN is both more common and more likely to have a malignant association in women, making it an entity with which practitioners of gynaecological ultrasound should be familiar.

A national multicentre study of outcomes and patient satisfaction with the virtual fracture clinic and the influence of the COVID-19 pandemic: The MAVCOV study.

Background: Virtual fracture clinics (VFCs) are advocated by the British Orthopaedic Association Standards for Trauma (BOAST). We aimed to assess the impact of the transition from face-to-face fracture clinic review and identify any change in clinical outcome and patient satisfaction.

Methods: A national, cross-sectional cohort study of VFCs across the UK over two separate two-week periods pre- and during the first UK COVID-19 lockdown was undertaken.

Making safe sense of an anti-sense!

Bepiroversen has been developed and trialed for the cure of HBV. Yuen et al. report on the safety and antiviral efficacy of this agent.

Is point-of-care testing feasible and safe in care homes in England? An exploratory usability and accuracy evaluation of a point-of-care polymerase chain reaction test for SARS-CoV-2.

Introduction: Reliable rapid testing for COVID-19 is needed in care homes to reduce the risk of outbreaks and enable timely care. This study aimed to examine the usability and test performance of a point of care polymerase chain reaction (PCR) test for detection of SARS-CoV-2 (POCKITTM Central) in care homes.

Methods: POCKITTM Central was evaluated in a purposeful sample of four UK care homes.

Pain in people living with HIV and its association with healthcare resource use, well being and functional status.

Objective: We describe the prevalence of pain and its associations with healthcare resource utilization and quality-of-life.

Design: The POPPY Study recruited three cohorts: older people living with HIV (PLWH; ≥50 years, n = 699), younger demographically/lifestyle similar PLWH (less than 50 years, n = 374) and older demographically/lifestyle similar HIV-negative (≥50 years, n = 304) people from April 2013 to February 2016.

Methods: Current pain and pain-related healthcare use was collected via a self-reported questionnaire.

An ethical appraisal of living-anonymous kidney donation using Adam Smith's Theory of Moral Sentiments.

Ethical debates continue to shape organ transplant policies, particularly for kidneys. Facing organ shortages, governments have created incentives targeting prospective living-anonymous donors - socially and biologically unrelated to the recipient. However, these policies may transform altruistic exchanges of tissues into trades of commodities.

Proteomic Analysis of Kveim Reagent Identifies Targets of Cellular Immunity in Sarcoidosis.

Background: Kveim-reagent (Kv) skin testing was a historical method of diagnosing sarcoidosis. Intradermal injection of treated sarcoidosis spleen tissue resulted in a granuloma response at injection site by 4-6 weeks. Previous work indicates proteins as the possible trigger of this reaction.

A prospective case control study of functional outcomes and related quality of life after colectomy for neoplasia.

Aim: Our aim was to assess bowel function and its effect on overall quality of life (QOL) when compared to healthy controls after colectomy.

Methods: Patients undergoing resection of colorectal neoplasia were recruited pre-operatively and followed up at 6 and 12 months, to assess 'early' bowel function. Patients who underwent surgery 2 to 4 years previously were recruited for assessment of 'intermediate' bowel function.

Can medical students accurately predict their learning? A study comparing perceived and actual performance in neuroanatomy.

It is important that clinicians are able to adequately assess their level of knowledge and competence in order to be safe practitioners of medicine. The medical literature contains numerous examples of poor self-assessment accuracy amongst medical students over a range of subjects however this ability in neuroanatomy has yet to be observed. Second year medical students attending neuroanatomy revision sessions at the University of Southampton and the competitors of the National Undergraduate Neuroanatomy Competition were asked to rate their level of knowledge in neuroanatomy.

Do ultrasound findings of levator ani "avulsion" correlate with anatomical findings: A multicenter cadaveric study.

Aims: This study aimed to validate the levator "avulsion" injury as seen on ultrasound against anatomical dissection in the same cadaver.

Methods: Puboviseral muscle (PVM) anatomy of female cadavers was studied using 3D-translabial ultrasonography and an "avulsion" confirmed per standard recommendations [Dietz HP. Aust N Z J Obstet Gynaecol 53:220-230, 2013].

Structural brain abnormalities in postural tachycardia syndrome: A VBM-DARTEL study.

Postural tachycardia syndrome (PoTS), a form of dysautonomia, is characterized by orthostatic intolerance, and is frequently accompanied by a range of symptoms including palpitations, lightheadedness, clouding of thought, blurred vision, fatigue, anxiety, and depression. Although the estimated prevalence of PoTS is approximately 5-10 times as common as the better-known condition orthostatic hypotension, the neural substrates of the syndrome are poorly characterized. In the present study, we used magnetic resonance imaging (MRI) with voxel-based morphometry (VBM) applying the diffeomorphic anatomical registration through exponentiated lie algebra (DARTEL) procedure to examine variation in regional brain structure associated with PoTS.

Undressing of Waddlia chondrophila to enrich its outer membrane proteins to develop a new species-specific ELISA.

Waddlia chondrophila, an obligate intracellular bacterium of the Chlamydiales order, is considered as an agent of bovine abortion and a likely cause of miscarriage in humans. Its role in respiratory diseases was questioned after the detection of its DNA in clinical samples taken from patients suffering from pneumonia or bronchiolitis. To better define the role of Waddlia in both miscarriage and pneumonia, a tool allowing large-scale serological investigations of Waddlia seropositivity is needed.

The impact of obesity surgery on musculoskeletal disease.

Obesity is an important modifiable risk factor for musculoskeletal disease. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-compliant systematic review of bariatric surgery on musculoskeletal disease symptoms was performed. One thousand nineteen papers were identified, of which 43 were eligible for data synthesis.

Assessment of surgical competence at carotid endarterectomy under local anaesthesia in a simulated operating theatre.

Background: Methods of surgical training that do not put patients at risk are desirable. A high-fidelity simulation of carotid endarterectomy under local anaesthesia was tested as a tool for assessment of vascular surgical competence, as an adjunct to training.

Methods: Sixty procedures were performed by 30 vascular surgeons (ten junior trainees, ten senior trainees and ten consultants) in a simulated operating theatre.
