Preceptor support during the COVID-19 pandemic: Recommendations for continuing development

Background: Mentally fit preceptors may be more capable and flexible in providing students with system, emotional and cognitive support in the clinical learning environment (CLE) in the face of any life-threatening outbreaks. Existing professional development programmes for preceptors emphasise the development of preceptor competence in a normal CLE with minimal focus on their ability to engage with adverse events that challenge their mental health. Objective: The study sought insight from preceptors' experiences during the coronavirus disease 2019 (COVID-19) pandemic to identify their professional development programme needs while providing support to students during accompaniment. Method: A mixed methods convergent parallel design was used to collect data from 24 preceptors at a nursing education institution (NEI). Eleven preceptors responded to the survey that included the coronavirus disease 2019 (COVID-19) Stress Scale (CSS) and Burnout Assessment Tool (BAT) to collect quantitative data. Semi structured interviews were conducted with five purposively selected preceptors to collect qualitative data regarding their experiences while accompanying students during the COVID-19 pandemic. Results: Subscales within the CSS and BAT instruments were mapped against an existing preceptor support framework. Overall CSS data for each subscale indicated an average score varying from no stress to moderate stress, while BAT data shows that respondents rarely experienced burnout. However, some respondents experienced very high levels of stress and burnout. Qualitative data supplemented results. Conclusion: The COVID-19 pandemic influenced preceptors' role in supporting students and reflecting that they amended their functioning role. Existing preceptor professional development programmes should be reviewed to ensure that the necessary concepts that foster resilience are integrated to enhance the functional role of preceptors in adversity.

Expanding the limits of endoscopic intraorbital tumor resection using 3-dimensional reconstruction / Expandindo os limites da ressecção endoscópica de tumor intraorbital utilizando reconstrução tridimensional

Abstract Introduction: Endoscopic orbital surgery is a nascent field and new tools are required to assist with surgical planning and to ascertain the limits of the tumor resectability. Objective: We purpose to utilize three-dimensional radiographic reconstruction to define the theoretical lateral limit of endoscopic resectability of primary orbital tumors and to apply these boundary conditions to surgical cases. Methods: A three-dimensional orbital model was rendered in 4 representative patients presenting with primary orbital tumors using OsiriX open source imaging software. A 2-Dimensional plane was propagated between the contralateral nare and a line tangential to the long axis of the optic nerve reflecting the trajectory of a trans-septal approach. Any tumor volume falling medial to the optic nerve and/or within the space inferior to this plane of resectability was considered theoretically resectable regardless of how far it extended lateral to the optic nerve as nerve retraction would be unnecessary. Actual tumor volumes were then superimposed over this plan and correlated with surgical outcomes. Results: Among the 4 lesions analyzed, two were fully medial to the optic nerve, one extended lateral to the optic nerve but remained inferior to the plane of resectability, and one extended both lateral to the optic nerve and superior to the plane of resectability. As predicted by the three-dimensional modeling, a complete resection was achieved in all lesions except one that transgressed the plane of resectability. No new diplopia or vision loss was observed in any patient. Conclusion: Three-dimensional reconstruction enhances preoperative planning for endoscopic orbital surgery. Tumors that extend lateral to the optic nerve may still be candidates for a purely endoscopic resection as long as they do not extend above the plane of resectability described herein.

Resumo Introdução: A cirurgia orbital endoscópica é um campo emergente e são necessárias novas ferramentas para auxiliar no planejamento cirúrgico e determinar os limites da ressecabilidade tumoral. Objetivo: Usar a reconstrução radiográfica tridimensional para definir o limite lateral teórico de ressecabilidade endoscópica de tumores orbitais primários e aplicar essas condições de limites a casos cirúrgicos. Método: Um modelo orbital tridimensional foi aplicado a quatro pacientes representativos com tumores orbitais primários utilizando o software de imagem de fonte aberta OsiriX. Um plano bidimensional foi propagado entre a narina contralateral e uma linha tangencial ao eixo longo do nervo óptico que reflete a trajetória de uma abordagem transeptal. Qualquer volume de tumor situado medialmente ao nervo óptico e/ou dentro do espaço inferior a esse plano de ressecabilidade foi teoricamente considerado ressecável, independentemente de quão longe ele se estendia até o nervo óptico, pois a retração do nervo seria desnecessária. Os volumes reais do tumor foram então sobrepostos sobre esse plano e correlacionados com os resultados cirúrgicos. Resultados: Entre as quatro lesões analisadas, duas eram totalmente mediais ao nervo óptico, uma se estendia lateralmente ao nervo óptico, mas permaneceu inferior ao plano de ressecabilidade, e uma se estendia lateralmente ao nervo óptico e superior ao plano de ressecabilidade. Conforme previsto pelo modelo tridimensional, uma ressecção completa foi obtida em todas as lesões, exceto uma, que transgrediu o plano de ressecabilidade. Nenhuma nova diplopia ou perda de visão foi observada em qualquer paciente. Conclusão: A reconstrução tridimensional melhora o planejamento pré-operatório para a cirurgia orbital endoscópica. Os tumores que se estendem lateralmente ao nervo óptico podem ainda ser candidatos à ressecção puramente endoscópica, desde que não se estendam além do plano de ressecabilidade aqui descrito.

Observing the stages of bystander intervention in virtual reality simulation / 世界急诊医学杂志（英文）

BACKGROUND@#Understanding bystander reactions to an emergency is an important component of effective training. Four stages of bystander intervention (BI) have been previously described: noticing the situation as a problem, interpreting when it is appropriate to intervene, recognizing personal responsibility to intervene, and knowing how to intervene. Using virtual reality (VR) to simulate emergencies such as sudden cardiac arrest (SCA) can be used to study these stages.@*METHODS@#In a secondary analysis of an observational cohort study, we analyzed bystander self-efficacy for stages of BI before and after simulated SCA. Each subject participated in a singleplayer, immersive, VR SCA scenario. Subjects interacted with simulated bystanders through voice commands (“call 911”, “get an AED”). Actions taken in scenario, like performing CPR, were documented. Scenario BI actions were compared based on dichotomized comfort/discomfort.@*RESULTS@#From June 2016 to June 2017, 119 subjects participated. Average age was 37±14 years, 44% were female and 46% reported CPR training within 2 years. During the scenario, 98% “noticed the event” and “interpreted it as a problem”, 78% “took responsibility”, and 54% “possessed the necessary skills”. Self-efficacy increased from pre- to post-scenario: noticing the event increased from 80% to 96%; interpreting as a problem increased from 86% to 97%; taking responsibility increased from 56% to 93%; possessing necessary skills increased from 47% to 63% (P<0.001).@*CONCLUSION@#Self-efficacy to respond to an SCA event increased pre- to post-scenario. Bystanders who reported feeling comfortable “taking responsibility to intervene” during an emergency were more likely to take action during a simulated emergency.

Variability of extracorporeal cardiopulmonary resuscitation utilization for refractory adult out-of-hospital cardiac arrest: an international survey study

OBJECTIVE: A growing interest in extracorporeal cardiopulmonary resuscitation (ECPR) as a rescue strategy for refractory adult out-of-hospital cardiac arrest (OHCA) currently exists. This study aims to determine current standards of care and practice variation for ECPR patients in the USA and Korea. METHODS: In December 2015, we surveyed centers from the Korean Hypothermia Network (KORHN) Investigators and the US National Post-Arrest Research Consortium (NPARC) on current targeted temperature management and ECPR practices. This project analyzes the subsection of questions addressing ECPR practices. We summarized survey results using descriptive statistics. RESULTS: Overall, 9 KORHN and 4 NPARC centers reported having ECPR programs and had complete survey data available. Two KORHN centers utilized extracorporeal membrane oxygenation only for postarrest circulatory support in patients with refractory shock and were excluded from further analysis. Centers with available ECPR generally saw a high volume of OHCA patients (10/11 centers care for >75 OHCA a year). Location of, and providers trained for cannulation varied across centers. All centers in both countries (KORHN 7/7, NPARC 4/4) treated comatose ECPR patients with targeted temperature management. All NPARC centers and four of seven KORHN centers reported having a standardized hospital protocol for ECPR. Upper age cutoff for eligibility ranged from 60 to 75 years. No absolute contraindications were unanimous among centers. CONCLUSION: A wide variability in practice patterns exist between centers performing ECPR for refractory OHCA in the US and Korea. Standardized protocols and shared research databases might inform best practices, improve outcomes, and provide a foundation for prospective studies.

Providers’ Perception of Quality of Care and Constraints to Delivery of Quality Maternal Health Services in Primary Health Centers of Enugu State, Nigeria.

Aims: The aim of the study was to assess providers’ perception of quality of care and constraints to delivery of quality maternal health services in urban and rural primary health centers of Enugu state, Nigeria. Study Design: This was a qualitative descriptive study. Methodology: A descriptive study design using qualitative data collection and analysis method. Data was collected through a face to face in-depth interview using an interview guide between May and June 2013. A total of 24 providers participated in the study. They included six heads of department of health of six local government areas and officers-in–charge of eighteen primary health centers in urban and rural areas of Enugu state, Nigeria. Results: Most of the providers perceived the quality of maternal health services in the primary health centers as good and they attributed this to results that were achieved. On measures the providers adopted to ensure clients satisfaction, most of the providers in the urban favoured good work attitude while those in the rural relied on provision of incentives. Inability of the health centers to remain open round the clock was identified as the major constraint to the delivery of quality maternal health care in the health centers and this was attributed to the prevailing security challenges in the study area. Other constraints included inadequate number of health workers, poor amenities, and inadequate equipment. Conclusion: The providers in the study area perceived good quality care to be the same as good utilization of services at the health centers. This has made them to adopt client friendly measures like good work attitude and use of incentives to encourage the clients to utilize the health centers. This may invariably lead to good quality care. Also, they view situations that limit access to services at the health centers as constraints to delivery of quality maternal health care. The providers need adequate support from the local government authorities who are the custodians of primary health care in Nigeria and they should also involve the host communities in the discharge of their duties. The primary health centers should be adequately fenced and personnel employed for security purposes as this will improve access primarily and then good quality care. There is also the need to train the health workers specifically on good quality care.

Biochemical Changes in Albino Rats Exposed to Rice Husk Dusk at Abakaliki Rice Mill Industrial Area.

The effect of rice husk dust inhalation on some biochemical parameters was conducted on albino rats. Method: 100 albino rats were divided into five groups with each group containing twenty albino rats. Group A served as the control and were housed at the animal house away from rice dust while group B, C, and D were exposed to rice husk dust for two week, three weeks and four weeks respectively for dust inhalation. They were allowed access to rats feeds and deionized water ad libitium. Blood samples were collected from each group at the end of exposure by cardiac puncture. Glucose level was determined using the glucose reagent kit, acid phosphatase concentration was performed using reagent kits, creatinine and uric acid concentration was determined spectrophotometrically, the weight of the rats were recorded daily. Results: Result showed significant reduction in body weight of the exposed. The glucose level decreased significantly while the serum acid phosphatase and serum uric acid level showed a significant increase. Histological result showed various degrees of damage to the kidney of the exposed rats. Conclusion: We therefore conclude that rice husk dust inhalation induces glucose depletion, injury to the kidney and prostatic glands in the albino rat and impairs the renal function.

Recognition and treatment of out-of-hospital cardiac arrests by non-emergency ambulance services in Singapore

<p><b>INTRODUCTION</b>Prompt recognition of cardiac arrest and initiation of cardiopulmonary resuscitation (CPR) and defibrillation is necessary for good outcomes from out-of-hospital cardiac arrest (OHCA). This study aims to describe the recognition and treatment of OHCA in patients conveyed by non-emergency ambulance services (EAS) in Singapore.</p><p><b>MATERIALS AND METHODS</b>This is a multi-centre, retrospective chart review, of cases presenting to public emergency departments (EDs), conveyed by non-EAS and found to be in cardiac arrest upon ED arrival. The study was from October 2002 to August 2009. The following variables were examined: ability to recognise cardiac arrest, whether CPR was carried out by the ambulance crew and whether an automated external defibrillator (AED) was applied.</p><p><b>RESULTS</b>Eighty-six patients were conveyed by non-EAS and found to be in cardiac arrest upon ED arrival. Mean age was 63 years (SD 21.8), 70.9% were males. A total of 53.5% of arrests occurred in the ambulance while 70.9% were found to be asystolic upon ED arrival. Seven patients had a known terminal illness. Survival to discharge was 3.5%. Cardiac arrest went unrecognised by the ambulance crew in 38 patients (44.2%). CPR was performed in 35 patients (40.7%) of the 86 patients and AED was applied in only 10 patients (11.6%).</p><p><b>CONCLUSION</b>We found inadequate recognition and delayed initiation of treatment for OHCA. Possible reasons include a lack of training in patient monitoring and detection of cardiac arrest, lack of CPR training, lack of confidence in performing CPR, lack of AEDs on ambulances and lack of training in their use.</p>

Opioid use amongst cancer patients at the end of life

<p><b>INTRODUCTION</b>Concerns about the life shortening effect of opioids is a well known fact in the medical world when considering administration of these drugs for symptom alleviation at end of life. This study described the patterns of opioid use among cancer patients referred to a hospital-based specialist palliative care service for symptom management. This study also examined whether opioid use among terminally ill cancer patients during the last 2 days of life had any influence on survival.</p><p><b>MATERIALS AND METHODS</b>A retrospective review of case notes of patients who were diagnosed with terminal cancer and had passed away in a 95-bedded oncology ward between September 2006 and September 2007 was conducted. Data were collected on patients' characteristics and patterns of opioid use including opioid doses and dose changes at 48 hours and 24 hours before death.</p><p><b>RESULTS</b>There were 238 patients who received specialist palliative care, of whom 132 (55.5%) were females. At 48 hours and 24 hours before death, 184 (77.3%) patients and 187 (78.6%) patients had received opioids, respectively. The median daily doses at 48 hours and 24 hours were 48 mg and 57 mg oral morphine equivalent doses (OME), respectively. Indications for opioid use were pain (41.1%), dyspnoea, (29.1%) and both dyspnoea and pain (30.8%). In the fi nal 24 hours, 22.3% patients had a reduction in their mean opioid dose while 22.7% required an increase in their mean opioid dose. Increased age was associated with decreasing opioid doses (P = 0.003). Patients with spinal metastases required higher doses of opioids (P = 0.03) while those with lung metastases required lower doses (P = 0.011). Survival analysis using Kaplan-Meier survival curve revealed no significant survival difference between those who were on opioids and those who were not. Log rank test (Mantel-Cox) (P = 0.69).</p><p><b>CONCLUSION</b>Our results showed that opioids are safe medications for symptom alleviation in terminally ill cancer patients during the last days of life and have no deleterious influence on survival.</p>

Impact of larviciding with a Bacillus thuringiensis israelensis formulation, VectoBac WG, on dengue mosquito vectors in a dengue endemic site in Selangor State, Malaysia.

The field bioefficacy of a wettable granule (WG) formulation of Bacillus thuringiensis israelensis (Bti), VectoBac WG (Bti strain AM65-52) against dengue vectors, Aedes aegypti and Ae albopictus; was evaluated in a suburban residential area (TST) and in a temporary settlement site (KB) in the state of Selangor, Malaysia. Pre-control ovitrap surveillance of the trial sites indicated a high population of both types of Aedes mosquitoes. The populations were monitored continuously by weekly ovitrapping. Bti was sprayed biweekly at a dosage of 500 g/ha by using a mist-blower. The spray application was targeted into outdoor larval habitats. If required, Bti formulation was also applied directly into indoor water-holding containers at 8 g/1,000 l. Based on ovitrap surveillance, a significant reduction in Aedes populations was evident 4 weeks after initiating the first Bti treatment. The ovitrap index (OI) and the larvae density decreased drastically in both trial sites. In TST, the indoor OI was significantly reduced from 57.50 +/- 7.50% to 19.13 +/- 5.49% (p<0.05), while the outdoor OI decreased from 38.89 +/- 11.11% to 15.36 +/- 5.93%. In KB, similarly, the OI was significantly reduced by more than half, from 66.66 +/- 6.67% to 30.26 +/- 2.99% (p< 0.05). In all cases, the reduction in OI was paralleled by reduction in larval density.

Hip fractures in the elderly: the impact of comorbid illnesses on hospitalisation costs

<p><b>INTRODUCTION</b>Hip fractures in the elderly are associated with multiple comorbidities.</p><p><b>MATERIALS AND METHODS</b>We prospectively surveyed and went through all relevant medical records of 70 consecutive patients admitted to Singapore General Hospital following either a cervical or intertrochanteric femoral fracture from late February to May 2004. The total hospitalisation cost for each patient was calculated based on the costs of inpatient care up to the point of discharge. Regression modeling was performed on the 7 commonest age-related conditions (based on our data), to determine the impact of each comorbidity on total costs.</p><p><b>RESULTS</b>The average age of the cohort was 77.24 years. The median length of stay was 13.6 days. In patients without comorbidities, the mean hospitalisation cost was S$9,347.5 +/- 1719.6. With the presence of comorbidities, the mean cost increased to S$11,502.3 +/- 6024.3. In univariate modeling, dementia added the largest amount to total costs [S$5,398; 95% confidence interval (CI), S$1273 to S$9523; P <0.05]. The presence of diabetes (S$758; 95% CI, S$2,051 to S$3,566), hypertension (S$644; 95% CI, S$1,986 to S$3,274) and osteoarthritis (S$915; 95% CI, S$3,721 to S$1,891) did not significantly add to total costs. When controlled for multiple comorbidities, dementia retained its significance in adding to total costs (S$6,178; 95% CI, S$1,795 to S$10,562; P = 0.006).</p><p><b>CONCLUSION AND DISCUSSION</b>Hip fracture patients with comorbidities incurred higher hospitalisation costs. Cost-containment strategies in hip fracture patients should not only examine the number of comorbidities but also the type of disease.</p>

Cleistanthus collinus poisoning.

Cleistanthus collinus is an extremely toxic plant poison. Cleistanthin A and B, the toxins of Cleistanthus collinus, are diphyllin glycosides which produce cardiac arrhythmias, urinary potassium wasting, hypoxia, metabolic acidosis and hypotension. We report ARDS, distal renal tubular acidosis and distributive shock secondary to inappropriate vasodilatation in a case following ingestion of its leaves.

Long-term results of radiofrequency ablation of slow pathway in patients with atrioventricular nodal reentrant tachycardia: single-center experience.

BACKGROUND: This study sought to evaluate the long-term recurrence rate of atrioventricular nodal reentrant tachycardia (AVNRT) after radiofrequency catheter ablation. The clinical and electrophysiological features of patients with AVNRT and their immediate outcomes after undergoing slow pathway ablation/modification were also studied. METHODS AND RESULTS: The study included 264 consecutive patients with AVNRT (mean age 46 -/+ 15 years, 143 women, 121 men) who underwent slow pathway ablation/modification using a combined electrophysiological and anatomical approach. The primary endpoint of ablation procedure was non- inducibility of the arrhythmia. The primary endpoint of the study was the recurrence of AVNRT on follow-up. Acute success was achieved in 262 (99.6%) patients. Complication rate of the ablation procedure was 2.6% and the average fluoroscopy time was 18.3 -/+ 11 minutes. The patients were followed up for a mean duration of 20 -/+ 9 months during which there was only one case of recurrence. CONCLUSION: Radiofrequency ablation or modification of slow pathway is highly effective in the treatment of AVNRT. The technique has a high initial success rate and a low complication rate. The recurrence rates are extremely low (0.3%) on long-term follow-up.

Rating chronic: discrepancy between cross-sectional and longitunal assessment

A bush-Francis Catatonia Rating Scale (BFCRS) e o primeiro instrumento valido desenvolvido exclusivamente para a avaliacao da sindrome catatonica. Neste estudo, os autores investigaram a hipotese de que a BFCRS pode ser valida e confiavel para a avaliacao transversal de condicoes catatonicas agudas e cronicas, mas ela pode ser inferior a observacao clinica longitudinal para fornecer informacao sobre a severidade de fenomenos catatonicos em pacientes com esquizofrenia cronica...
