An investigation into academic career pathways across Radiography education centres internationally

INTRODUCTION

Robust academic pathways are critical to support of radiography faculty within third level education. As the profession of Radiography grows its' research activity, it is important that academic opportunities meet the needs of the profession. The purpose of this research was to investigate current academic career pathways across radiography education centres internationally.

METHODS

An online survey was developed and administered to radiography academics and clinical/academic staff members internationally. The survey questions (n = 28) include demographic data; teaching and research requirements; academic promotion criteria; identification of the challenges and benefits of being an academic, including equality, diversity and inclusion (EDI) matters.

RESULTS

A total of 175 responses were obtained (6 continents and 39 countries), with a variety of experience levels amongst academics that primarily held permanent work contracts. Regarding the highest qualifications held, 31.4% (n = 55) had a Doctorate and 45.7% (n = 80) a Master's degree, and most respondents were employed as academic lecturers (40.6%; n = 71), with 17.7% (n = 31) employed at professorial level. The minimum time requirement to achieve a permanent contract was variable, ranging from no delay (5.7%; n = 10) to more than 10 years (12.6%; n = 22). Doctorate qualification is currently not necessary in order to career progression for 126 (72%) respondents, while 52% (n = 91) provided specific research requirements. 106 (60.6%) respondents indicated that their institution has EDI policy.

CONCLUSION

This study has captured details related to academic pathways across international radiography education centres. Whilst some heterogeneity exists, there are numerous differences impacting standardised academic career opportunities for Radiography academics. These may challenge academic career opportunities and discourage those interested in an academic career.

IMPLICATIONS FOR PRACTICE

The profile and educational background of these academics has been highlighted as well as the perceived barriers and advantages of a career in academic.

National survey for investigating the diagnostic imaging departments reorganization and management during the COVID-19 pandemic

Introduction

The COVID-19 pandemic has had a profound impact on radiography services globally. The objective of this study was to evaluate the impact of the COVID-19 pandemic on the management of radiology departments in Italy.

Methods

An online survey with 32 questions was developed and promoted by the Italian Federation of Scientific Radiographer Societies (FASTeR) and sent to all Radiology Service Managers (RSM) identified in the RSM committee of the Italian Federation of Radiographers and Health Professionals, counting for 39 Italian RSM, representing more than 1,200 radiographers. The survey included questions regarding RSM demographics data, the number of radiographers and specialties managed, the effects of the pandemic on the diagnostic imaging service, and any reorganizations that had been implemented, such as the partial or total suspension of diagnostic activities and the number of radiographers tested as positive to COVID-19.

Results

Twenty (52%) RSM from different Italian regions completed the questionnaire. A total of 70% of respondents had implemented reorganizations in terms of space, equipment, and pathways dedicated to COVID-19-infected patients, including an extension of the timing of acquisition of the exams. More than half of the respondents reported breast and DXA imaging unit had suffered the most suspension of activities. 70% of respondents reported that more than 50% of radiographers were resulted as COVID-19 positive.

Conclusion

These data show how challenging was of the reorganization of Italian diagnostic imaging departments during the COVID-19 pandemic, with impact on the suspension of some exams and the rescheduling of breast and DXA imaging. The reorganization of the services also had to consider the high number of radiographers suspended from activity due to the positivity to COVID-19, and the lengthening of the duration of the examinations due to the sanitation of the spaces.

Analysis and management of the COVID-19 pandemic impact on a multispecialty diagnostic imaging department

Introduction

The propose of this study was to evaluate the impact of the first two waves of the COVID-19 pandemic on a multispecialty radiology department in a large tertiary university hospital in Northern Italy.

Methods

The numbers of all radiological exams performed in the radiology department of Scientific Institute for Research, Hospitalization and Healthcare (namely, IRCCS) Policlinico San Donato (San Donato Milanese, Italy) from March 2019 to March 2021 were collected and compared, subdividing them both temporally, modality, sub-specialty, and setting.

Results

Comparing the first 12 months of the COVID-19 pandemic (from March 2020 to February 2021) with the previous 12 months (from March 2019 to February 2020), there was an overall decrease in total radiological examinations equal to 26% (from 127,998 to 94,550). The most affected modality was DXA (from 4,706 to 2,989, -36%), followed by ultrasonography (from 17,212 to 11,644, -32%), digital radiography (from 66,050 to 47,374, -28%), MRI (from 13,332 to 10,140, -24%), CT (from 19,208 to 15,746, -18%), and mammograms (from 7,490 to 6,657, -11%). Chest CTs of inpatients saw a +15% surge (from 1,087 to 1,144), with far larger sizable increments being observed for chest X-ray examinations of outpatients (from 3,032 to 7,536, +131%). Further sub-analysis according to pandemic waves highlighted an overall -65% decrease of radiological services during the first wave (from March to May 2020), curtailed to -3% during the June–October period and then again rising to -23% during the second wave (from November 2020 to February 2021).

Conclusion

The COVID-19 pandemic led to a marked decrease of total radiological examinations during the two pandemic waves, limited to -26% by the implementation of safety protocols during the second wave and by increased activity during the inter-wave period.

Pain distraction during awake low anterior resection and Cuddle Delivery initiative for inpatient: frugal procedural options to support surgery in the COVID-19 era

OBJECTIVE

Since minimally invasive surgery and general anesthesia are both aerosol-generating procedures, their use became controversial during the outbreak of coronavirus disease 2019 (COVID-19). Moreover, social distancing resulted in serious psychological consequences for inpatients. This case report investigates pain distraction during awake laparotomy, as well as new possibilities for emotional postoperative support to inpatients.

PATIENTS AND METHODS

A 72-year-old man affected by middle rectal adenocarcinoma underwent lower anterior resection plus total mesorectal excision under combined spinal-epidural anesthesia. A 3D mobile theatre (3DMT) was intraoperatively used for pain distraction. A postoperative "Cuddle delivery" service was instituted: video-messages from relatives and close friends were delivered daily to the patient through the 3DMT. Emotional correlations were investigated through a clinical interview by the psychologist of our Hospital.

RESULTS

Intraoperative, as well as postoperative pain, resulted well-controlled: visual analogue scale (VAS) ≤3. Conversion to general anesthesia and postoperative intensive support/monitoring were unnecessary. The "Cuddle delivery" initiative positively fed our patient's mood and attitude, strengthening his bond to life.

CONCLUSIONS

During pandemic, awake laparotomy under loco-regional anesthesia may be a crucial option in delivering acute care surgery to selected patients when intensive care beds are unavailable. Our procedure introduces potential ways to optimize this approach.

The impact of COVID-19 upon student radiographers and clinical training

Introduction

To investigate student clinical placement concerns and opinions, during the initial COVID-19 pandemic outbreak and to inform educational institution support planning.

Methods

Between mid-June to mid-July 2020, educational institutions from 12 countries were invited to participate in an online survey designed to gain student radiographer opinion from a wide geographical spread and countries with varying levels of COVID-19 cases.

Results

1277 respondents participated, of these 592 had completed clinical placements during January to June 2020. Accommodation and cohabiting risks were identified as challenging, as was isolation from family, travel to clinical placements, and to a lesser extent childcare. Students stated they had been affected by the feeling of isolation and concerns about the virus whilst on placement. Overall 35.4% of all respondents were ‘Not at all worried’ about being a radiographer, however, 64.6% expressed varying levels of concern and individual domestic or health situations significantly impacted responses (p ≤ 0.05). Year 4 students and recent graduates were significantly more likely to be ‘Not worried at all’ compared to Year 2 and 3 students (p ≤ 0.05). The need for improved communication regarding clinical placements scheduling was identified as almost 50% of students on clinical placements between January to June 2020 identified the completion of assessments as challenging. Furthermore, only 66% of respondents with COVID-19 imaging experience stated being confident with personal protective equipment (PPE) use.

Conclusion

Student radiographers identified key challenges which require consideration to ensure appropriate measures are in place to support their ongoing needs. Importantly PPE training is required before placement regardless of prior COVID-19 imaging experience.

Implications for practice

As the next academic year commences, the study findings identify important matters to be considered by education institutions with responsibility for Radiography training and as students commence clinical placements during the on-going global COVID-19 pandemic.

Technique and protocols for cardiothoracic time-resolved contrast-enhanced magnetic resonance angiography sequences: a systematic review

AIM

To review contrast medium administration protocols used for cardiothoracic applications of time-resolved, contrast-enhanced magnetic resonance angiography (MRA) sequences.

MATERIALS AND METHODS

A systematic search of the literature (Medline/EMBASE) was performed to identify articles utilising time-resolved MRA sequences, focusing on type of sequence, adopted technical parameters, contrast agent (CA) issues, and acquisition workflow. Study design, year of publication, population, magnetic field strength, type, dose, and injection parameters of CA, as well as technical parameters of time-resolved MRA sequences were extracted.

RESULTS

Of 117 retrieved articles, 16 matched the inclusion criteria. The study design was prospective in 9/16 (56%) articles, and study population ranged from 5 to 185 patients, for a total of 506 patients who underwent cardiothoracic time-resolved MRA. Magnetic field strength was 1.5 T in 13/16 (81%), and 3 T in 3/16 (19%) articles. The administered CA was gadobutrol (Gadovist) in 6/16 (37%) articles, gadopentetate dimeglumine (Magnevist) in 5/16 (31%), gadobenate dimeglumine (MultiHance) in 2/16 (13%), gadodiamide (Omniscan) in 2/16 (13%), gadofosveset trisodium (Ablavar, previously Vasovist) in 1/16 (6%). CA showed highly variable doses among studies: fixed amount or based on patient body weight (0.02-0.2 mmol/kg) and was injected with a flow rate ranging 1-5 ml/s. Sequences were TWIST in 13/16 (81%), TRICKS in 2/16 (13%), and CENTRA 1/16 articles (6%).

CONCLUSION

Time-resolved MRA sequences were adopted in different clinical settings with a large spectrum of technical approaches, mostly in association with different CA dose, type, and injection method. Further studies in relation to specific clinical indications are warranted to provide a common standardised acquisition protocol.

Management of patients with suspected or confirmed COVID-19, in the radiology department

OBJECTIVES

From December 2019, a novel coronavirus disease named COVID-19 was reported in China. Within 3 months, the World Health Organization defined COVID-19 as a pandemic, with more than 370,000 cases and 16,000 deaths worldwide. In consideration of the crucial role of diagnostic testing during COVID-19, the aim of this technical note was to provide a complete synthesis of approaches implemented for the management of suspected or confirmed COVID-19 patients.

KEY FINDINGS

The planning of a robust plan to prevent the transmission of the virus to patients and department staff members should be fundamental in each radiology service. Moreover, the speed of spread and the incidence of the pandemic make it necessary to optimize the use of personal protective devices and dedicated COVID-19 equipment, given the limited availability of supplies.

CONCLUSION

In the management of radiographic and CT imaging, staff should take special precautions to limit contamination between patients and other patients or professionals.

IMPLICATIONS FOR PRACTICE

An isolated imaging room should be dedicated to suspected or confirmed COVID-19 cases, including radiography and CT scanners. This paper will provide guidance concerning disposable protective gear to be utilized, as well as on the cleaning and sanitation of radiology room and equipment.

Dark fermentation, anaerobic digestion and microbial fuel cells: An integrated system to valorize swine manure and rice bran

This work describes how dark fermentation (DF), anaerobic digestion (AD) and microbial fuel cells (MFC) and solid-liquid separation can be integrated to co-produce valuable biochemicals (hydrogen and methane), bioelectricity and biofertilizers. Two integrated systems (System 1: AD+MFC, and System 2: DF+AD+MFC) are described and compared to a traditional one-stage AD system in converting a mixture (COD=124±8.1gO2kg(-1)Fresh Matter) of swine manure and rice bran. System 1 gave a biomethane yield of 182 LCH4kg(-1)COD-added, while System 2 gave L yields of bio-hydrogen and bio-methane of 27.3±7.2LH2kg(-1)COD-added and 154±14LCH4kg(-1)COD-added, respectively. A solid-liquid separation (SLS) step was applied to the digested slurry, giving solid and liquid fractions. The liquid fraction was treated via the MFC-steps, showing power densities of 12-13Wm(-3) (500Ω) and average bioelectricity yields of 39.8Whkg(-1)COD to 54.2Whkg(-1)COD.

Barcoding Eophila crodabepis sp. nov. (Annelida, Oligochaeta, Lumbricidae), a Large Stripy Earthworm from Alpine Foothills of Northeastern Italy Similar to Eophila tellinii (Rosa, 1888)

A new Italian earthworm morphologically close to the similarly large and anecic Eophila tellinii (Rosa, 1888) is described. Distribution of Eophila crodabepis sp. nov. extends over 750 km² from East to West on the Asiago Plateau and Vittorio Veneto Hills, from North to South on mounts Belluno Prealps (Praderadego and Cesen), Asiago, Grappa and onto the Montello foothills. This range abuts that of Eophila tellinii in northern Friuli Venezia Giulia region. Known localities of both E. tellinii and E.crodabepis sp. nov. are mapped. mtDNA barcoding definitively separates the new western species from classical Eophila tellinii (Rosa, 1888).

Mixed Nodule Infection in Sinorhizobium meliloti-Medicago sativa Symbiosis Suggest the Presence of Cheating Behavior

In the symbiosis between rhizobia and legumes, host plants can form symbiotic root nodules with multiple rhizobial strains, potentially showing different symbiotic performances in nitrogen fixation. Here, we investigated the presence of mixed nodules, containing rhizobia with different degrees of mutualisms, and evaluate their relative fitness in the Sinorhizobium meliloti-Medicago sativa model symbiosis. We used three S. meliloti strains, the mutualist strains Rm1021 and BL225C and the non-mutualist AK83. We performed competition experiments involving both in vitro and in vivo symbiotic assays with M. sativa host plants. We show the occurrence of a high number (from 27 to 100%) of mixed nodules with no negative effect on both nitrogen fixation and plant growth. The estimation of the relative fitness as non-mutualist/mutualist ratios in single nodules shows that in some nodules the non-mutualist strain efficiently colonized root nodules along with the mutualist ones. In conclusion, we can support the hypothesis that in S. meliloti-M. sativa symbiosis mixed nodules are formed and allow non-mutualist or less-mutualist bacterial partners to be less or not sanctioned by the host plant, hence allowing a potential form of cheating behavior to be present in the nitrogen fixing symbiosis.

Anastomotic leakage following colorectal resection for cancer: how to define, manage and treat it

AIM

Aim of the study was to report the experience of a single center in the surgical treatment of anastomotic leak after colorectal resection for cancer, focusing on its incidence, diagnosis and management, with particular attention to surgical options.

METHODS

Demograhic and clinical data from 1284 consecutive patients operated on for colorectal cancer during a period of 11 years, were prospectively collected and inserted into an electronic database. For the purpose of the study, only patients in whom an anastomosis was performed were considered. Therefore, 128 patients (9.9%) were excluded and 1156 represent the study population. All complications occurring after surgery were systematically recorded. The incidence of colorectal anastomotic leak (CAL), its management and outcome was analyzed.

RESULTS

An ileo-colic anastomosis was performed in 426 cases (36.8%), ileo-rectal in 29 (2.5%), colo-colic in 409 (35.4), colo-rectal with partial mesorectal excision in 211 (18.3%) and lower colorectal or coloanal anastomosis with total mesorectal excision and temporary loop ileostomy in 81 (7%). Colorectal anastomotic leak occurred in 78/1156 patients (6.7%), accounting for 19% of overall complications. Thirty-six out of 78 patients (46.2%) were successfully treated conservatively, whereas 42 (53.8%) underwent re-operation. Nine out of 78 patients (11.5%) with CAL died owing to an uncontrolled sepsis. All had undergone previous re-intervention, with a post-operative mortality rate of 21.4% (9 out of 42).

CONCLUSION

Mortality rate in patients undergoing re-operation for colorectal anastomotic leakeage is still high, and accounts for up to 40% of the deaths after colorectal resection for cancer. In the light of these data, strategic clinical decisions are mandatory to optimize the selection of patients who need an early and fast surgical approach. What does this paper add to the literature? Systematic and prospective data recording is an essential tool to assess the quality of healthcare and to plan quality improvement programs. Every effort should be done to reach an early diagnosis of CAL, possibly in a pre-clinical phase in which non clinical methods could be used to predict it.

Microbiological features and bioactivity of a fermented manure product (preparation 500) used in biodynamic agriculture

The fermented manure derivative known as Preparation 500 is traditionally used as a field spray in biodynamic agriculture for maintaining and increasing soil fertility. This work aimed at characterizing the product from a microbiological standpoint and at assaying its bioactive properties. The approach involved molecular taxonomical characterization of the culturable microbial community; ARISA fingerprints of the total bacteria and fungal communities; chemical elemental macronutrient analysis via a combustion analyzer; activity assays for six key enzymes; bioassays for bacterial quorum sensing and chitolipooligosaccharide production; and plant hormonelike activity. The material was found to harbor a bacterial community of 2.38 × 10(8) CFU/g dw dominated by Grampositives with minor instances of Actinobacteria and Gammaproteobacteria. ARISA showed a coherence of bacterial assemblages in different preparation lots of the same year in spite of geographic origin. Enzymatic activities showed elevated values of beta-glucosidase, alkaline phosphatase, chitinase, and esterase. The preparation had no quorum sensing-detectable signal, and no rhizobial nod gene-inducing properties, but displayed a strong auxin-like effect on plants. Enzymatic analyses indicated a bioactive potential in the fertility and nutrient cycling contexts. The IAA activity and microbial degradation products qualify for a possible activity as soil biostimulants. Quantitative details and possible modes of action are discussed.

Pelvic lymphedema in rectal cancer: a magnetic resonance feasibility study: a preliminary report

BACKGROUND

Functional pelvic disorders in patients undergoing conservative surgical approach for rectal cancer are considered a major public health issue and represent one third of cost of colorectal cancer. We investigated the hypothesis that lymphadenectomy, involves the pelvic floor results in a localized hides or silent pelvic lymphedema characterized by symptoms without signs.

PATIENTS AND METHODS

We examined 13 colo-rectal cancer patients: five intra-peritoneal adenocarcinoma: 1 sigmoid and 4 upper third rectal cancer (1 male and 3 female) and 9 extra-peritoneal adenocarcinoma: 3 middle and 5 lower third rectal cancer (4 male and 5 female) using 1.5-T magnetic resonance, one week before and twelve months after discharged from hospital.

RESULTS

Lymphedema was discovered on post-operative magnetic resonance imaging of all 9 patients with extra-pertitoneal cancer, whereas preoperative magnetic resonance imaging as well as a post-operative examination of 4 intra-peritoneal adenocarcinoma, revealed no evidence of lymphedema. Unlike the common clinical skin signs that typify all other sites of lymphedema, pelvic lymphedema is hides or silent, with no skin changes or any single symptom manifested. Magnetic resonance imaging showed that pelvic illness alone is accompanied by lymphedema related exclusively to venous congestion, and accumulation of liquid in adipose tissue or lipedema.

CONCLUSIONS

Alteration of the pelvic lymphatic network during pelvic surgery can lead to lymphedema and, pelvic floor disease. Patients should be routinely examined for the possibility of developing this post-surgical syndrome and further studies are needed to establish diagnosis and to evaluate treatment preferences.

Vascular Remodeling After Carotid Artery Stenting

Carotid stenting is an alternative to endarterectomy for the treatment of carotid stenosis. To determine the role of vascular remodeling after stent placement, we studied 19 high surgical risk patients undergoing carotid stenting for severe stenosis. Using high-resolution ultrasound, we evaluated the intima-media thickness (IMT), the intima-intima diameter, and the adventitia-adventitia diameter at prespecified sites of the carotid artery tree during 3 years of follow-up. The IMT of internal carotid artery, at the site of maximum stenosis, increased significantly from 0 mm after 24 hours, to 0.41 mm at 3 months, to 0.48 mm at 6 months, and to 0.51 mm at 3 years of follow-up. In the same site, diameters and residual stenosis (range 29-24%) did not change over time. Our study showed that stent is self-expanding against the atherosclerotic plaque within the 3-year follow-up period. Despite neointima formation, the intima-intima diameter does not change without worsening of the residual stenosis.

[Anastomotic fistulas after colorectal resection for carcinoma: incidence and treatment in our recent experience]

AIM

The incidence of anastomotic fistula after colorectal surgery did not significantly change in the literature during the last years, despite the advances in the treatment with the use of surgical staplers. Taking into account this and other considerations, the authors present their recent experience in the surgical treatment of colorectal carcinoma, referring in particular to anastomotic fistula, related postoperative mortality and results of consequent reoperations.

METHODS

From January 1, 2002 to December 31, 2005, 448 patients affected with colorectal cancer were operated on at the Surgical Department of Valduce Hospital in Como, and in 373 cases an anastomosis was performed, subdivided as follows: 144 ileocolic (38.6%), 10 ileorectal (2.7%), 219 colocolic or colorectal (58.7%).

RESULTS

Twenty-five out of 373 anastomotic leaks developed (6.7%). In 9 cases (36%), the fistulas spontaneously closed with conservative treatment, while in 16 (64%) reoperation was necessary. With reference to the anatomical site, the leak occurred in 9 out of 144 patients submitted to right hemicolectomy (6.3%), in 14 out of 219 patients after left hemicolectomy or anterior resection of the rectum (6.4%) and in 2 out of 10 patients (20%) after total colectomy. The following is a detailed report of the therapeutic choices adopted by the authors. Four out of 16 reoperated patients (25%) died postoperatively from infective complications related to the fistula, while the total postoperative mortality was 2.2% (10/448). Therefore, anastomotic dehiscence was responsible for 40% of all postoperative deaths.

CONCLUSIONS

Among all the different operative choices, the authors give their preference to the direct suture of the fistula and loop ileostomy, which they consider the best available choice. The subsequent operation of ileostomy closure is easier for the surgeon to perform and for the patient to withstand than colostomy closure, particularly after Hartmann's operation.

[Angiosarcoma of the breast after conservative surgery and radiotherapy for early breast carcinoma. Description of a case]

The occurrence of an angiosarcoma of the residual breast after conservative surgery and adjuvant radiotherapy for early mammary carcinoma is a very rare event. In western countries only 57 cases have been published in the literature (5 in Italy) since the first described case in 1987. Radiotherapy seems to be the most important etiological factor in the development of the neoplasm. Diagnosis is often delayed, owing to the "benign" aspect of the lesion. The only effective treatment is residual mastectomy, because chemotherapy is ineffective. The prognosis is often dismal, because of the aggressive behaviour of the lesion in most cases. The case of a patient with a multicentric secondary angiosarcoma of the breast recently operated on is described.

[Laparoscopic cholecystectomy. Our clinical experience from 1994 to 1996]

BACKGROUND AND AIM

Videolaparocholecystectomy is now regarded as the gold standard of treatment for lithiasis of the gallbladder.

METHODS

The authors report a retrospective of 258 consecutive videolaparocholecystectomies performed by the Surgical Division of Valduce Hospital in Como between 1994 and 1996. The authors describe the indications for VLC, techniques for the induction of pneumoperitoneum and the realisation of VLC and the percentage and caused of conversion.

RESULTS

During this period a steady reduction was noted in the number of laparotomic cholecystectomies and a parallel increase in cholecystectomies performed using a laparoscopic technique (69.2 vs. 30.8% in 1994; 76.4 vs. 23.2% in 1995; 91.1 vs. 8.9% in 1996). A gradual extension of the indications for laparoscopic surgery can be seen leading to the application of this technique in patients suffering from acute cholecystic infection, hydros or empyema of the gallbladder. Conversion were required in 25 cases in this series (9.7%). During the last year analysed there were a total of 9 conversions (7.9%) even though the percentage of acute cholecystitis accounted for 38.9% of all cases of cholecystectomy.

CONCLUSIONS

In line with the experience of other centres, the authors, currently propose VLC as the treatment of choice for lithiasic pathologies of the cholecyst.
