ented.Obstetric forceps were invented in the 1600s to assist vaginal delivery of term babies following prolonged labour. This probably explains their design, with a narrow interblade distance and long blade length, to fit a severely moulded fetal head. However, in modern obstetric practice protracted labour is avoided, yet our research has shown that over 400 years forceps dimensions have remained largely unchanged. We believe it is time to optimise these dimensions based on biometry of the term, newborn baby's head, with the head width (biparietal diameter) and head length (mentovertical diameter) correlating with interblade distance and blade length respectively. We hypothesise that doing so should reduce the incidence of neonatal complications associated with forceps assisted delivery and it is also possible that the amended shape might be associated with better outcomes for women. In this article we present our rationale for the optimisation of the forceps dimensions based on the findings of our previous systematic review and an original series of mentovertical and biparietal diameter measurements using laser scanning technology.

This study aimed to investigate the predictive value of laparoscopy for the prediction of optimal cytoreduction and prognosis of epithelial ovarian cancer (EOC) in a Chinese population.

This study enrolled 162 EOC patients in Obstetrics and Gynecology Hospital of Fudan University from January 2015 to December 2016. All patients underwent preoperative CT scans and laparoscopic assessments. Each patient was scored according to the CT-based predictive model by Bristow and laparoscopy-based predictive model by Fagotti. The specificity, sensitivity, positive predictive value (PPV), negative predictive value (NPV) and area under the curve (AUC) of each model were calculated. The predictive scores and clinicopathologic factors were all analyzed using the Kaplan-Meier method and multivariate Cox analysis. A prognostic predictive nomogram was formulated in R software.

The AUCs of the laparoscopy-based predictive model and CT-based predictive model was 0.955 and 0.755 respectively. At a laparoscopic score ≥ 10, t good potential to predict the prognosis of EOC patients.

Aiming at analysing the signal conduction in muscular fibres, the spatio-temporal dynamics of the magnetic field generated by the propagating muscle action potential (MAP) is studied.

In this prospective, proof of principle study, the magnetic activity of the intrinsic foot muscle after electric stimulation of the tibial nerve was measured using optically pumped magnetometers (OPMs). A classical biophysical electric dipole model of the propagating MAP was implemented to model the source of the data. In order to account for radial currents of the muscular tubules system, a magnetic dipole oriented along the direction of the muscle was added.

The signal profile generated by the activity of the intrinsic foot muscles was measured by four OPM devices. Three OPM sensors captured the spatio-temporal magnetic field pattern of the longitudinal intrinsic foot muscles. Changes of the activation pattern reflected the propagating muscular action potential along the muscle. A combined electric and magnetic dipole moynamics of the MAP is possible. The classic electric dipole model explains major but not all aspects of the magnetic field. The field has longitudinal components generated by intrinsic structures of the muscle fibre. By understanding these magnetic components, new methods could be developed to analyse the muscular signal transduction pathway in greater detail. The approach has the potential to become a promising diagnostic tool in peripheral neurological motor impairments.

Accuracy in diagnosing osteoarthritis in the midfoot using weightbearing plain radiography (WBPR) remains questionable due to the overlapping osseous architecture present, occluding visualization. Weightbearing computed tomography (WBCT), providing clearer bony landmark identification and joint space visualization, can also be used for evaluation. The aim of this project is to perform a standardized retrospective intra-patient analysis identifying the discrepancy of midfoot osteoarthritis diagnosis and osteoarthritis severity grading between WBPR and WBCT.

A cohort of 302 patient feet was acquired from an internal, consecutive patient database using detailed inclusion criteria. The musculoskeletal radiologist interpretation of the WBCT and WBPR of each specimen was then assessed for any direct diagnosis or mention of osteoarthritic signs in specific articulations of 3 midfoot joint groups (Chopart, "central", and tarsometatarsal). WBPR sensitivity and specificity metrics were calculated with WBCT considered the gold standard for comparison.

From the WBPR radiologist interpretation, we found diagnostic sensitivity of 72.5 % and specificity of 87.9 % for Chopart joints; 61.5 % sensitivity, and 96.1 % specificity for central joints; and 68.4 % sensitivity, and 92.9 % specificity for tarsometatarsal joints. The severity of degenerative changes was also consistently underestimated when interpreted from WBPR relative to WBCT.

In this series, midfoot osteoarthritis was often undetected on WBPR. WBCT imaging facilitates an earlier, more reliable diagnosis and grading of midfoot osteoarthritis relative to WBPR.

This study aimed to evaluate knowledge, attitude, practice and emotional and psychological concerns related to COVID-19 pandemic among radiology technicians working at pandemic hospitals across Turkey METHODS A total of 228 radiology technicians working at pandemic hospitals across Turkey were included on a voluntary basis in this questionnaire-based online survey The questionnaire form elicited items on socio-demographic and occupational characteristics and personal opinions and experience on COVID-19 outbreak and related protective strategies, along with survey scales including Knowledge on COVID-19 Outbreak Scale (KCS), Knowledge on Protective Strategies for COVID-19 Scale (KPSCS), General Preventive Practices for COVID-19 Scale (GPPCS), Emotional State Scale (ESS) and Fear of COVID-19 Scale (FCS).

Males had lower ESS (p = 0.004) scores and higher FCS (p = 0.026) scores than females. Having a COVID-19 training (63.4 %) was associated with higher KCS (p = 0.006) and PSCS (p < 0.001) scores, while higher KCS was also related with higher PSCS (p < 0.
