RESUMO

BACKGROUND: Global healthcare systems have been particularly impacted by the COVID-19 pandemic. Healthcare workers (HCWs) are widely reported to have experienced increased levels of baseline psychological distress relative to the general population, and the COVID-19 pandemic may have had an additive effect. However, previous studies are typically restricted to physicians and nurses with limited data available on hospital HCWs. We aimed to conduct a cross-sectional, psychological evaluation of Irish HCWs during COVID-19. METHODS: HCWs across five adult acute level-4 Dublin-based hospitals completed an online survey of wellbeing and COVID-19 experience. RESULTS: There were 1898 HCWs who commenced the survey representing 10% of the total employee base. The sample comprised nurses (33%), doctors (21%), Health and Social Care Professionals (HSCPs) (24%) and 'Other' disciplines (22%), and 81% identified as female. Clinical levels of depression, anxiety and PTSD symptoms were endorsed by 31%, 34% and 28% of respondents, respectively. Professional grouping effects included: nurses reporting significantly greater levels of COVID-19 exposure, infection, COVID-fear, moral injury, and post-traumatic distress; HSCPs were significantly less likely to report mood dysfunction. In terms of gender, males were significantly less likely to report negative pandemic experiences, low resilience, and significantly more likely to endorse 'minimal' depression, anxiety, and traumatic distress. Logistic regression modelling revealed mental health outcomes (depression, anxiety and PTSD symptoms) were associated with increased frontline exposure, fewer career years' experience, elevated pre-pandemic stress, and female gender. DISCUSSION: To our knowledge, this is the largest evaluation of psychological wellbeing amongst HCWs in acute hospitals in the Dublin region. Our findings have implications for healthcare workforce wellbeing and future service delivery.

RESUMO

Impinging dorsal spinous processes (IDSP) are typically diagnosed and graded using radiography, during which the effect of the horses' thoracolumbar posture on the interspinous spaces is not commonly considered. Posture can be altered from a spontaneous, relatively extended, or lordotic, position by manual facilitation of thoracic flexion ('thoracic lift'). This study aimed to ascertain if the thoracic vertebral interspinous space distances were increased by using facilitated thoracic flexion to alter the posture in horses diagnosed with IDSP. Seven horses of mixed breed and sex, median age 9.1 years (interquartile range, 7.2-12.4 years), with a diagnosis of thoracic IDSP with no history of spinal surgery, were included in the study. Two sets of radiographs were obtained. The initial set was taken in the horses' spontaneous posture and the second in the manually facilitated flexed posture. Each image was anonymised allowing blinded measurement of the interspinous spaces. Analysis was performed using Hodges-Lehmann median differences estimates. An increase in the median interspinous space distance was achieved after manual facilitation of thoracic flexion at every thoracic intervertebral space (5th-18th thoracic [T] vertebra). The greatest median increase was seen between T7-T8 and T12-T13 (3.1 mm and 3.0 mm, respectively) whereas the lowest median increase was seen between T17-T18 (0.7 mm). In this study, thoracic interspinous space distances could be increased by using manual facilitation to alter the thoracic posture in horses with IDSP, which could affect grading and decision making.

RESUMO

LITERATURE REVIEW: Cystoscopy is the gold standard for initial macroscopic assessments of the human urinary bladder to rule out (or diagnose) bladder cancer (BCa). Despite having guidelines, cystoscopic findings are diverse and often challenging to classify. The extent of the false negatives and false positives in cystoscopic diagnosis is currently unknown. We suspect that there is a certain degree of under-diagnosis (like the failure to detect malignant tumours) and over-diagnosis (e.g. sending the patient for unnecessary transurethral resection of bladder tumors with anesthesia) that put the patient at risk. CONCLUSIONS: XAI robot-assisted cystoscopes would help to overcome the risks/flaws of conventional cystoscopy. Cystoscopy is considered a less life-threatening starting point for automation than open surgical procedures. Semi-autonomous cystoscopy requires standards and cystoscopy is a good procedure to establish a model that can then be exported/copied to other procedures of endoscopy and surgery. Standards also define the automation levels-an issue for medical product law. These cystoscopy skills do not give full autonomy to the machine, and represent a surgical parallel to 'Autonomous Driving' (where a standard requires a human supervisor to remain in the 'vehicle'). Here in robotic cystoscopy, a human supervisor remains bedside in the 'operating room' as a 'human-in-the-loop' in order to safeguard patients. The urologists will be able to delegate personal- and time-consuming cystoscopy to a specialised nurse. The result of automated diagnostic cystoscopy is a short video (with pre-processed photos from the video), which are then reviewed by the urologists at a more convenient time.

RESUMO

The inextricable link between medicine and the legal profession has flourished in the 21st century, with countless newspaper articles and social media content on medical cases visible at every juncture. This is particularly true in the speciality of obstetrics and gynaecology, with one of the highest rates of litigation of all medical specialities. We aimed to evaluate the influence of media and the legal environment on the career of trainees in obstetrics and gynaecology. Under the auspices of the Irish national training body, we distributed a 26-item questionnaire to doctors-in-training (DIT) working in obstetrics and gynaecology in the Republic of Ireland. Descriptive statistics and Chi-squared analyses were performed on the anonymised data. 151 DIT responded to the questionnaire, with a response rate of 86.2 % (sample size = 175). The majority were female (79.9 %, n = 121), Irish (85.5 %, n = 106) and had no children (67.0 %, n = 83). 86.7 % (n = 131) felt that the media did not have a positive impact on patients receiving care, and, further, unfairly represented the speciality (94.1 %; n = 142). Additionally, DIT felt that medico-legal issues had a negative impact on issues such as retention and recruitment. These two areas were implicated in over three quarters of DIT considering leaving the speciality. This study demonstrates that DIT perceive media scrutiny and litigation to have a negative effect on the speciality of obstetrics and gynaecology. Further support integrated into specialist training, is needed to ensure that trainees are adequately equipped to deal with both mainstream and social media as well as interactions they may have with the legal profession as they progress through their career.

RESUMO

AIMS: Stereotactic ablative radiation therapy (SABR) is a standard of care for medically inoperable early stage non-small cell lung carcinoma. Tumours greater than 5 cm have been excluded from randomised trials using SABR and, hence, it is not used as a standard for larger lung tumours. However, improvements in radiation therapy techniques and the success of SABR in treatment of early stage disease may allow safe delivery of ablative doses to larger tumours. We analysed our experience with tumours ≥5 cm to determine the efficacy and toxicity profile of SABR in this setting. MATERIALS AND METHODS: We evaluated survival, control rates, patterns of failure and toxicity in patients with a tumour diameter larger than 5 cm that had no nodal or distant metastases treated with SABR technology. Patients had been treated in two centres since 2009 and were retrospectively analysed. All patients had positron emission tomography staging, were discussed at a tumour board and were documented to have no nodal or distant metastatic disease. Treatment outcomes were analysed using Kaplan-Meier estimates and compared using the Log-rank test. Cox regression was used to investigate the association between the survival outcomes and predictor variables. RESULTS: In total, 86 patients were identified. Six patients had no follow-up imaging. Therefore, 80 patients were available for analysis. All patients were reclassified according to the updated AJCC eighth edition. The median follow-up was 19.6 months. No patients received neoadjuvant or concurrent systemic therapy. One patient received adjuvant systemic therapy. The median age at treatment was 77 years (range 58-91). Eighty-four per cent were stage T3N0M0 and 16% were staged T4N0M0. The median tumour diameter was 5.8 cm (range 5.0-9.3 cm). The median gross tumour volume, measured on a single phase of the respiratory cycle, was 45.7 cm3 (range 12.1-203.3 cm3). The median overall survival was 20.9 months (95% confidence interval 12.6-29.1 months). One-, 2- and 3-year overall survival was 71%, 48% and 32%, respectively. The median local failure-free survival was 19.5 months (95% confidence interval 14.4-24.6). The median disease-free survival was 15.1 months (95% confidence interval 9.9-20.4 months). Local control at 1, 2 and 3 years was 85% (95% confidence interval 76-94%), 71% (95% confidence interval 58-84%) and 57% (95% confidence interval 40-74%), respectively. Forty-four patients (55%) had any treatment failure (local, mediastinal, intrapulmonary or distant metastases). Out-of-field intrapulmonary disease progression was the most common mode of failure, occurring in 21 patients (26%). Local failure occurred in 19 patients (24%) - alone or in combination with other progression. Distant metastases occurred in 20 patients (25%). Neither histological subtype, tumour size nor gross tumour volume had a statistically significant effect on local failure-free survival. Two patients experienced grade 3 late dyspnoea. There were no other reported grade 3 or higher acute or late toxicities. CONCLUSION: SABR for larger lung tumours ≥5 cm results in high local control and acceptable survival in patients with medically inoperable large non-small cell lung carcinoma treated with radiation alone. Such patients should be considered for SABR owing to fewer treatment fractions and acceptable toxicity. Local control analysis reveals a sustained pattern of local failure emphasising the need for long-term follow-up. Improvements in technical strategies are required to further improve local control.

RESUMO

Aim To compare the relative efficiencies of skin excisions in primary and secondary care. Methods We compared the benign: malignant ratio for specimens referred by General Practice, General Surgery and the Skin Cancer Service to the regional pathology laboratory over one month. We used cost minimization analysis to compare the relative efficiencies of the services. Results 620 excisions were received: 139 from General Practice, 118 from General Surgery and 363 from the Skin Cancer Service. The number (%) of malignant lesions was 13 (9.4%) from General Practice, 18 (15.2%) from General Surgery and 137 (37.7%) from the Skin Cancer Service. Excision was cheaper in General Practice at €84.58 as compared to €97.49 in the hospital day surgical unit. However, the cost per malignant lesion excised was €1779.80 in general practice versus €381.78 in the Skin Cancer Service. Conclusion Our results indicate that moving skin cancer treatment to General Practice may result in an excess of benign excisions and therefore be both less efficient and less cost effective.

RESUMO

INTRODUCTION: Isolated pancreatic body transection secondary to blunt abdominal trauma is a very rare injury associated with poor outcomes. Almost all previously reported cases were managed by emergency distal pancreatectomy, which is associated with high morbidity and mortality. To our knowledge, this is the first reported case of complete transection of the pancreas at the body that was successfully treated by conservative management in an adult patient. PRESENTATION OF CASE: A 19-year-old male was found to have complete transection of the pancreatic body on computed tomography (CT) following blunt force abdominal trauma. Given that he was haemodynamically stable without evidence of haemorrhage or bile leakage on imaging, a trial of conservative management was initiated. He remained well through his admission, gradually improving clinically and biochemically with stable appearances on serial imaging. He remains asymptomatic as of six months since discharge from the hospital and continues to be monitored in the outpatient setting. DISCUSSION: Management of pancreatic trauma with ductal injury has typically been with emergency distal pancreatectomy, which is associated with high morbidity and mortality. The decision to operate should not be purely based on radiological findings, and should take into account clinical status, haemodynamic stability, coexisting injuries and evidence of active haemorrhage or bile leak. CONCLUSION: In select cases, it is reasonable to trial conservative management in isolated traumatic pancreatic body fracture by means of close clinical observation and serial imaging. This may allow the patient to avoid a high-risk emergency distal pancreatectomy.

RESUMO

Basal cell carcinoma (BCC) are the commonest cutaneous malignancy and incidence continues to increase. There is a need to expand the therapeutic toolbox to increase options for patients that are unsuitable for or unwilling to undergo the current therapies. Electrochemotherapy (ECT) is a technique where cells are temporarily permeabilized after exposure to a brief pulsed electrical field and combined with low dose chemotherapeutics to ablate malignancies. It is a simple technique causing minimal damage to the surrounding healthy tissue and has the potential to avoid the need for complex reconstruction. ECT is an established treatment for skin metastases but its role as a primary treatment modality is not demonstrated. A prospective randomised control trial evaluating ECT against the gold standard of treatment, Surgery, was performed for patients with primary BCC and patients followed for 5 years. All lesions treated with ECT (n = 69) responded although 8/69 (12%) needed a second treatment to ensure a complete response. All surgical lesions (n = 48) showed histological evidence of complete excision with 2/48 (4%) undergoing a second excision. At 5 years, in the surgical arm there was no evidence of recurrence in 39/40 (97.5%) lesions with 1/40 (2.5%) confirmed recurrence. In the ECT arm there was no evidence of recurrence in 42/48 lesions (87.5%). There was 5 confirmed recurrences. These groups show statistical equivalence in this non inferiority study design (p = 0.33). ECT is an effective and durable treatment option for primary BCC and should be considered as part of the armamentarium of options available.

RESUMO

BACKGROUND AND PURPOSE: We have previously reported that endocannabinoids modulate permeability in Caco-2 cells under inflammatory conditions and hypothesised in the present study that endocannabinoids could also modulate permeability in ischemia/reperfusion. EXPERIMENTAL APPROACH: Caco-2 cells were grown on cell culture inserts to confluence. Trans-epithelial electrical resistance (TEER) was used to measure permeability. To generate hypoxia (0% O2), a GasPak™ EZ anaerobe pouch system was used. Endocannabinoids were applied to the apical or basolateral membrane in the presence or absence of receptor antagonists. KEY RESULTS: Complete hypoxia decreased TEER (increased permeability) by ~35% after 4 h (recoverable) and ~50% after 6 h (non-recoverable). When applied either pre- or post-hypoxia, apical application of N-arachidonoyl-dopamine (NADA, via TRPV1), oleamide (OA, via TRPV1) and oleoylethanolamine (OEA, via TRPV1) inhibited the increase in permeability. Apical administration of anandamide (AEA) and 2-arachidonoylglycerol (2-AG) worsened the permeability effect of hypoxia (both via CB1). Basolateral application of NADA (via TRPV1), OA (via CB1 and TRPV1), noladin ether (NE, via PPARα), and palmitoylethanolamine (PEA, via PPARα) restored permeability after 4 h hypoxia, whereas OEA increased permeability (via PPARα). After 6 h hypoxia, where permeability does not recover, only basolateral application PEA sustainably decreased permeability, and NE decreased permeability. CONCLUSIONS AND IMPLICATIONS: A variety of endocannabinoids and endocannabinoid-like compounds modulate Caco-2 permeability in hypoxia/reoxygenation, which involves multiple targets, depending on whether the compounds are applied to the basolateral or apical membrane. CB1 antagonism and TRPV1 or PPARα agonism may represent novel therapeutic targets against several intestinal disorders associated with increased permeability.

RESUMO

AIMS: Cannabidiol (CBD) is a cannabis-derived medicinal product with potential application in a wide-variety of contexts; however, its effective dose in different disease states remains unclear. This review aimed to investigate what doses have been applied in clinical populations, in order to understand the active range of CBD in a variety of medical contexts. METHODS: Publications involving administration of CBD alone were collected by searching PubMed, EMBASE and ClinicalTrials.gov. RESULTS: A total of 1038 articles were retrieved, of which 35 studies met inclusion criteria covering 13 medical contexts. Twenty-three studies reported a significant improvement in primary outcomes (e.g. psychotic symptoms, anxiety, seizures), with doses ranging between <1 and 50 mg/kg/d. Plasma concentrations were not provided in any publication. CBD was reported as well tolerated and epilepsy was the most frequently studied medical condition, with all 11 studies demonstrating positive effects of CBD on reducing seizure frequency or severity (average 15 mg/kg/d within randomised controlled trials). There was no signal of positive activity of CBD in small randomised controlled trials (range n = 6-62) assessing diabetes, Crohn's disease, ocular hypertension, fatty liver disease or chronic pain. However, low doses (average 2.4 mg/kg/d) were used in these studies. CONCLUSION: This review highlights that CBD has a potential wide range of activity in several pathologies. Pharmacokinetic studies as well as conclusive phase III trials to elucidate effective plasma concentrations within medical contexts are severely lacking and highly encouraged.

RESUMO

Aims To assess the quality of care in both the initial management of obstetric anal sphincter injury (OASI) and subsequent follow up postnatally in a tertiary maternity hospital without direct access to a perineal clinic. Methods Medical records were reviewed over a one-year period in University Maternity Hospital Limerick (UMHL) to determine the characteristics of patients sustaining OASI, how and where the repair was undertaken, the complications recorded and their follow up in the postpartum period. This pathway of care was compared with care currently available in three dedicated perineal clinics nationally. Results There were 44 patients with OASI recorded over a one-year period in UMHL. The majority were diagnosed in primiparous women having an operative vaginal delivery (OVD). Only 23 of 44 women had a documented review postnatally. Conclusion Audit of OASI is paramount to providing the best standard of care for affected women. It also aids clinician training and will be important in the establishment of a dedicated perineal clinic in UMHL.

RESUMO

INTRODUCTION: The importance of postoperative drain fixation cannot be overemphasised. There are numerous described techniques for drain fixation. However, to our knowledge, there is no evidence-based comparison between the various techniques of drain fixation used in postoperative management. We describe a new method and compare its reliability with four other commonly used methods. MATERIALS AND METHODS: Five methods were chosen for testing based on current trends in clinical practice: centurion sandal with plastic locking ties, centurion sandal or lattice method, centurion sandal with half-inch Steristrips®, double and multiple looped methods. We used an Instron 8872® tensiometer to apply a measured force to a secured drain. Each fixation method was tested ten times and all fixation methods were performed by the same experienced surgeon. We measured the average number of cycles before failure, the average displacement of the tube at failure and the time needed to apply each fixation method. RESULTS: The number of cycles completed before failure showed that the centurion sandal method, the centurion sandal with plastic ties and the centurion sandal method with Steristrips had the lowest failure rate. The amount of displacement was the least in the centurion sandal with plastic ties followed by the double-loop method and centurion sandal with Steristrips. There was little difference in the time taken to complete the fixation methods (range 21-33 seconds). DISCUSSION: We recommend the use of the centurion sandal with plastic locking ties, centurion sandal with Steristrips followed by the centurion sandal method alone as fixation techniques that are quick to perform, secure and reliable.

RESUMO

Introduction Dopamine transporter scans are increasingly being used in the diagnosis of clinically undefined Parkinsonism. Aims To assess the indications for imaging usage and its impact on future clinical management. Methods Retrospective review of scans ordered and their corresponding results over a five-year period. A chart review was carried out on a cohort of scans to assess changes in clinical management. Results One hundred and eighty scans (69% of total) were reported as showing evidence of dopaminergic deficit. A chart review in 81 patients showed a change in clinical management in 53 patients (65%). Scans were ordered inappropriately in 34 patients (13%). Discussion 123I-FP-CIT SPECT scans are being more frequently ordered and if used correctly can alter clinical management. Increased education on indications for use is required to reduce waste of resources and risk to patients.

RESUMO

AIMS: The objective of this phase II clinical trial was to prospectively evaluate the safety and efficacy of accelerated hypofractionated three-dimensional conformal radiation therapy (3DCRT) in localised non-resectable/non-operable non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: Sixty patients with stage I-III NSCLC were enrolled in a prospective single-arm All Ireland Co-operative Oncology Research Group (ICORG 99-09) toxicity end point phase II trial. The protocol allocated patients between three radiation schedule dose levels (60, 66 or 72 Gy, in 20, 22 and 24 fractions, respectively, 3 Gy daily, five fractions per week) according to combined lung V25Gy (V25Gy ≤ 30%) with built-in early stopping toxicity rules. The primary end point was toxicity with evaluation of dose-limiting toxicity. The secondary objectives included radiological tumour response rate at 3 months after the completion of radiation therapy and the thoracic progression-free survival time. RESULTS: Sixty patients were recruited from August 1999 to June 2009. Forty-nine patients were included in the primary per-protocol analysis. Eleven patients were not evaluable. In the first 30 evaluable patient cohort, severe oesophageal toxicity was reported in two patients (2/49; 4% experiencing grade 5 oesophageal late toxicity, related to the 97% oesophageal length). The trial was temporarily closed and was then reopened to validate an oesophageal dose volume constraint (DVC) of limiting the length of oesophagus fully encompassed by the 97% isodose to less than 1 cm (applied to 21 patients). The trial prospectively showed the safety of the oesophageal DVC, with no oesophageal toxicity above grade 3 thereafter. Thirty-nine per cent of patients had disease progression at 3-4 months after radiotherapy, 22% had stable disease, 20% had a complete response and 14% had a partial response. The median overall survival was 13.6 months (95% confidence interval 10.5-16.7) and overall survival at 1 and 3 years was 57% and 29%, respectively. CONCLUSION: A strategy using accelerated hypofractionated 3DCRT is feasible and reasonably safe for patients with inoperable NSCLC. It is safe to deliver for centrally located tumours if DVCs are applied to the oesophagus, which is the primary dose-limiting toxicity. Further studies are required to assess the efficacy of hypofractionated regimens for centrally located tumours using an oesophageal DVC and monitoring for oesophageal toxicity.

RESUMO

A Piscirickettsia salmonis infection was diagnosed in lumpfish (Cyclopterus lumpus L.) juveniles held in a marine research facility on the west coast of Ireland. The main clinical signs and pathology included marked ascites, severe multifocal liver necrosis and severe diffuse inflammation and necrosis of the exocrine pancreas and peri-pancreatic adipose tissue. Numerous Piscirickettsia-like organisms were observed by histopathology in the affected organs, and the bacterial species was characterized by molecular analysis. Sequencing of the partial 16S rDNA gene and internal transcribed spacer region showed the lumpfish sequences to be closely related to previously identified Atlantic salmon (Salmo salar L.) sequences from Ireland. To the authors' knowledge, this is the first detection of P. salmonis in lumpfish worldwide. The infection is considered potentially significant in terms of lumpfish health and biosecurity.

RESUMO

Aesthetic plastic surgery is a consumer-driven industry, subject to influence by financial forces. A changing economic environment may thus impact on the demand for surgery. The aim of this study was to explore trends in demand for bilateral breast augmentation (BBA) in consecutively presenting patients over an 11-year period and to examine if a correlation exists between these trends and changes in Gross Domestic Product (GDP), a key economic indicator. This study revealed a correlation between annual number of breast augmentation procedures performed and GDP values (r 2 = 0.34, p value = 0.059). Additionally, predicted number of BBA procedures, based on predicted GDP growth in Ireland, strongly correlated with actual number of BBA performed (r 2 = 0.93, p value = 0.000001). Predicted GDP growth can potentially forecast future demand for BBA in our cohort allowing plastic surgeons to modify their practice accordingly.

RESUMO

OBJECTIVES: The asylum process has received a lot of recent media attention but little has been said about the psychological needs of those seeking or granted asylum. Many asylum seekers have experienced trauma and torture, which is associated with substantial psychiatric and psychological morbidity. The Spiritan Asylum Services Initiative (Spirasi) is Ireland's national treatment centre for survivors of torture. The aim of this study was to examine the demographic profile of those attending Spirasi and to consider potential clinical implications of this. METHODS: We retrospectively analysed demographic data relating to the 2590 individuals who attended Spirasi over a 12-year period (2001-2012 inclusive). RESULTS: The majority of attenders were asylum seekers (88%), male (71%) and from African countries. The mean age was 31.9 years. The rate of new referrals, as a percentage of Ireland's asylum-seeking population, has stabilised at ~6% since 2008. Women are underrepresented among those who attend. CONCLUSIONS: The number of new referrals to Spirasi is lower than expected given international estimates of torture prevalence and the impact this has on mental health. Clinicians working with populations of asylum seekers and refugees should sensitively enquire about such events and be aware of the available services. Female refugees and asylum seekers are underrepresented, especially from Asian and Middle Eastern regions. Psychiatric, psychological and general practice services need to respond flexibly to evolving patterns of migration and address potential barriers to access, especially among female refugees and asylum seekers.
