Abstract
Effective physician-patient communication builds robust physician-patient relationships and reduces medical disputes. However, much is unknown about the differences that exist in the communication behaviors of physicians in different departments. Using a mixed-methods research approach, the researchers used Roter Interaction Analysis System to uncover the communication behaviors of internists, surgeons, family physicians, and emergency physicians at a regional hospital in Taiwan. Semi-structured interviews were conducted to collect the communication experiences of 20 physicians from the internal medicine, surgery, family medicine, and emergency departments. The characteristics were presented through descriptive statistics, bar charts, and dendrograms. Physician-patient communications consisted of four dimensions, 10 factors, and 31 behaviors. The characteristics are as follows: (1) Internists need to improve their overall performance in terms of physician-patient communication behaviors; (2) Surgeons performed well in building relationships through non-verbal methods; (3) Family physicians excelled in facilitation and patient activation. (4) Emergency physicians performed well in patient education and counseling. The characteristics of the aforementioned communication behaviors among internists, surgeons, family physicians, and emergency physicians can be used to construct indicators of physician-patient communication in each department and to develop patient-centered healthcare services in the future.

Abstract
INTRODUCTION Healthcare contributes more than 1% of all domestic waste in the United Kingdom (UK), with operating theatre waste alone accounting for approximately 50% of all hospital waste. In November 2022, the UK Surgical Royal Colleges issued an Intercollegiate Climate Emergency Declaration and called for urgent action. We review waste production and the recyclability of surgical instrument packaging used in a common ear, nose and throat procedure (thyroidectomy) and suggest strategies to make this surgery more sustainable,. These strategies can be generalised to other surgeries. METHODS We prospectively audited packaging waste from 20 thyroidectomies performed at the Royal Marsden Hospital in the UK between July and December 2022. All packaging was weighed, categorised and analysed after the operation. RESULTS On average, each thyroidectomy produced packaging waste comprising 183g (34%) of plain paper/cardboard, 167g (31%) of soft plastic film, 142g (26%) of laminated paper, 37g (7%) of hard plastic and 11g (2%) of metal foil. Of all the packaging collected, only one item had a recycling label. When extrapolated to the 7,851 thyroidectomies performed in the National Health Service during the fiscal year 2021/2022, the estimated total weight of packaging waste would be 4.2 tonnes, of which only 31.4kg would be indicated as recyclable. When converted to an estimated carbon footprint, total carbon emissions would be 1,048kg CO2e, equivalent to three round trips from London to Edinburgh in a petrol car. CONCLUSION This audit demonstrates the different categories and vast amount of packaging waste from a common operation. Manufacturers should place clear recyclability labels on packaging, and switch to recyclable materials and a digital information booklet where possible. Local waste audit and analysis can be simple first steps towards making surgery more sustainable.

Differences in patient-physician communication between the emergency department and other departments in a hospital setting in Taiwan. BMC Health Serv Res 2023; 23:1279. [PMID: 37986078 PMCID: PMC10662510 DOI: 10.1186/s12913-023-10311-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Accepted: 11/09/2023] [Indexed: 11/22/2023] Open
Abstract
BACKGROUND Communication fosters trust and understanding between patients and physicians, and specific communication steps help to build relationships. Communication in the emergency department may be different from that in other departments due to differences in medical purposes and treatments. However, the characteristics of communication in the clinical settings of various departments have not been explored nor compared. OBJECTIVES This study aimed to construct the steps in patient-physician communication based on the Roter Communication Model and compare communication performance between the emergency department and three other clinical settings-internal medicine, surgery, and family medicine departments. METHODS Both qualitative and quantitative approaches were adopted. First, in-depth interviews were used to analyze clinical communication steps and meanings. Then, a quantitative questionnaire was designed based on the interview results to investigate differences in communication between the emergency department and the other three departments. Qualitative and quantitative data were analyzed from 20 interviews and 98 valid questionnaires. RESULTS Patient-physician communication consists of four steps and ten factors. The four steps-greeting and data gathering, patient education and counseling, facilitation and patient activation, and building a relationship-had significant progressive effects. Patient education and counseling had an additional significant effect on building a relationship. The emergency department performed less well in the facilitation and patient activation, building a relationship step and the evaluation method, enhancement method, and attitude factors than the other departments. CONCLUSIONS To improve the quality of patient-physician communication in the emergency department, physicians should strengthen the steps of facilitation and patient activation to encourage patients' active engagement in their health care.

Abstract
PURPOSE/OBJECTIVE(S) Studieson the role of surgery and local treatment in M1 rectal cancer have been actively studied recently. However, there is still controversy because no significant results have been reported for local control. The purpose of this study was to analyze the local control rates of postoperative radiotherapy for tumor stage T4 in M1 rectal cancer. MATERIALS/METHODS We investigated local recurrence after surgery for M1 rectal cancer that was operated at Seoul St. Mary's Hospital between 1995 and 2021. Locoregional recurrence rates were compared in patients who received postoperative pelvic radiotherapy and those who did not. In addition, an analytical comparison was performed only for patients with T4 rectal cancer. Statistical analysis was performed using the log rank test, and a p-value of less than 0.05 was considered significant. RESULTS During the investigation period, a total of 206 patients underwent surgery for M1 rectal cancer. There were 55 patients with T4 tumor stage. Of the 55 patients, 11 patients received radiotherapy after surgery, and 44 patients received systemic treatment such as chemotherapy after surgery without radiotherapy. During a median follow-up of 22 months, locoregional recurrence occurred in 1 (RT group) and 25 (no RT group) patients, respectively. Log-rank analysis of locoregional recurrence showed a significant difference between the two groups (p- value = 0.008). Death occurred in 10 (RT group) and 38 (no RT group) patients, respectively. The 2-year locoregional recurrence free-survival rates were 45.5% and 53.0%, respectively, and there was no significant difference between the two groups in the log-rank analysis. CONCLUSION Pelvic radiotherapy could be expected to improve locoregional recurrence in stage T4 of rectal cancer with synchronous distant metastasis. It would be warranted to prove this in a large-scale prospective study.

Abstract
PURPOSE/OBJECTIVE(S) As a basic hypothesis for the effectiveness of flash radiation therapy, the effect of preserving normal tissue during flash radiation is due to the instantaneous chemical depletion of oxygen. A yeast-based biological phantom was created to verify the hypoxic effect of flash radiation therapy. A study to upgrade the previously developed X-Band LINAC to a flash irradiation mode is in progress, and a preceding study is conducted to evaluate the usefulness of a yeast-based biological phantom manufactured by analyzing the change in oxygen by irradiating a high dose in a general radiation therapy device. MATERIALS/METHODS Freeze-dried yeast sample (Saccharomyces cerevisiae, S288C) is activated and sub-cultured. For mass production of yeast samples, yeast culture medium is prepared by adding yeast colonies to the ypd medium. This study was conducted to verify the hypoxic effect among the biological mechanisms that occur during flash radiation therapy at the basic stage, and the oxygen concentration change during general radiation irradiation was measured in real time using a DO (Dissolved oxygen) meter and fiber optic sensor designed to do that. To prevent scatter, which is a concern during flash irradiation, the fiber form was used, and precise experiments are possible as a non-invasive oxygen concentration measurement method. Based on 10MV of general radiation therapy device, high-dose radiation of 500-10,000 cGy is irradiated to measure real-time oxygen concentration change. RESULTS As a result of irradiation with high-dose (500-10,000 cGy) radiation of general LINAC, it was confirmed that the oxygen concentration of the yeast culture medium decreased by 5.7-63.2%, and the usefulness of the biological phantom fabricated based on the yeast culture medium was evaluated. CONCLUSION Prior to the analysis of oxygen concentration change in yeast cells during X-Band LINAC flash irradiation, a preliminary study was conducted at a high dose in a general LINAC to obtain a significant result of oxygen concentration change and confirm the usefulness of the yeast-based biological phantom. Prior research was conducted and verified as a general irradiation experiment using a yeast-based biological phantom manufactured based on a DO meter and a fiber optic oxygen sensor. After irradiation with high-dose radiation, the oxygen concentration of the yeast culture medium was measured 5 times, and it was confirmed that there was a change in oxygen concentration of 5.7-63.2%, verifying the usefulness and stability of the biological phantom. The usefulness of the yeast-based biological phantom for high doses was confirmed, and it is expected that the usefulness of the biological phantom for flash radiation can be verified by additionally measuring the change in oxygen concentration of the biological phantom according to the high dose rate in the future.

Multi-disciplinary management of type 1 and 2 skin tears using a silver-based hydrofiber dressing. Medicine (Baltimore) 2023; 102:e35112. [PMID: 37713868 PMCID: PMC10508467 DOI: 10.1097/md.0000000000035112] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 08/16/2023] [Indexed: 09/17/2023] Open
Abstract
Skin tear is a common problem encountered in the emergency department. If it is not properly managed, it can lead to wound infection, skin necrosis and a need for further surgical intervention and skin grafting. Current management is to cleanse the wound, replace the thin skin tear followed by coverage with a dressing that is inducive for wound healing. Several dressings have been suggested for the coverage of these wounds. But, up to now, there has been no mention of the use of a silver-based hydrofiber dressing in the management of this condition. The objective of this study was to explore the use of a silver-based hydrofiber dressing for the management of paper-thin skin tears. We retrospectively reviewed all patients with Type 1 or 2 skin tears that had undergone management using a silver-based hydrofiber dressing between October 2019 and October 2020. Demographic data and medical history was obtained by retrospective chart review. Data that was collected included: age, sex, comorbid illnesses, defect location, defect size, complications, number of times the silver-based hydrofiber dressing was replaced and the number of days required to achieve complete wound healing. A total of 65 patients were included in the study. There were 42 males and 23 females. There were 28 patients whose age was greater then 85 years old, of which 14 patients were over 90 years old. The mean number of outpatient visits was 2. The mean defect size was 33 cm2 (range 1 cm × 1 cm to 18 × 10 cm). The mean number of days required for total wound healing was 13 days (range 7-21). We did not encounter any patients that required further surgical debridement or split-thickness skin grafting. The use of a silver-based hydrofiber dressing was well tolerated by the elderly population as it provided an easy, efficient, economical and effective form of management of skin tears. We suggest that a silver-based hydrofiber dressing can be used as a first-line treatment method for type 1 and 2 skin tears.

Abstract
Abstract
Introduction
The ageing population poses challenges to the health care industry worldwide. The huge demand for residential care home for the elderly (RCHE) services induces pressure on health care workers (HCWs) recruitment and retention. HCWs are personnel who have prominent roles in direct basic care to the older adults, and all kinds of hands-on care. Due to the “unpleasant” work nature, shift work, and physical demands for HCWs, it is essential to unfold how HCWs comprehend their working experiences.
Methods
An integrative review was conducted to synthesize various streams of literature in order to generate new knowledge. Multiple databases such as CINAHL, ERIC, LWW nursing were adopted to search for relevant literature published between 2012 and 2022.
Results
A total of 24 articles were retrieved at the initial stage, and 7 articles were sorted after in-depth review. In general, results supported that HCWs experienced positively on the works at RCHEs though there were job stresses. The HCWs perceived the roles at RCHEs as routinized and task-oriented by providing direct care to older adults. They perceived their roles at RCHEs as care providers who provided direct care to older adults. Also, their responsibilities to maintain the safety and dignity of older adults was expressed as utmost importance. The meaning of works lay on three levels: interpersonal (e.g. self-achievement), interpersonal (e.g. communication with team members), and job performance (e.g. task compliance).
Conclusions
This study reveals the experiences of working at RCHE from the HCWs’ perspective. The HCWs’ experiences reflected in this study as well as the meaning of works discovered can generate insights for policy-makers on HCWs recruitment and retention.

Trends of Regional Anesthesia Studies in Emergency Medicine: An Observational Study of Published Articles. West J Emerg Med 2022; 23:878-885. [DOI: 10.5811/westjem.2022.8.57552] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Accepted: 08/27/2022] [Indexed: 11/13/2022] Open
Abstract
Introduction: Regional anesthesia (RA) has become a prominent component of multimodal pain management in emergency medicine (EM), and its use has increased rapidly in recent decades. Nevertheless, there is a paucity of data on how RA practice has evolved in the specialty. In this study we sought to investigate how RA has been implemented in EM by analyzing trends of published articles and to describe the characteristics of the published research.
Methods: We retrieved RA-related publications from the SciVerse Scopus database from inception to January 13, 2022, focusing on studies associated with the use of RA in EM. The primary outcome was an analysis of trend based on the number of annual publications. Other outcomes included reports of technique diversity by year, trends in the use of individual techniques, and characteristics of published articles. We used linear regression analysis to analyze trends.
Results: In total, 133 eligible publications were included. We found that overall 23 techniques have been described and results published in the EM literature. Articles related to RA increased from one article in 1982 to 18 in 2021, and the rate of publication has increased more rapidly since 2016. Reports of lower extremity blocks (60.90%) were published most frequently in ranked-first aggregated citations. The use of thoracic nerve blocks, such as the erector spinae plane block, has increased exponentially in the past three years. The United States (41.35%) has published the most RA-related articles. Regional anesthesia administered by emergency physicians (52.63%) comprised the leading field in published articles related to RA. Most publications discussed single-shot (88.72%) and ultrasound-guided methods (55.64%).
Conclusion: This study highlights that the number of published articles related to regional anesthesia in EM has increased. Although RA research has primarily focused on lower extremity blocks, clinical researchers continue to broaden the field of study to encompass a wide spectrum of techniques and indications.

The Effect and Safety of Rapid and Gradual Urinary Decompression in Urine Retention: A Systematic Review and Meta-Analysis. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:1441. [PMID: 36295601 PMCID: PMC9609720 DOI: 10.3390/medicina58101441] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 10/03/2022] [Accepted: 10/09/2022] [Indexed: 09/06/2023]
Abstract
Background and objectives: Trials to evaluate the effect and safety of rapid and gradual urinary decompression have been published for decades. Due to inconclusive results, this study aimed to assess whether rapid bladder decompression increased complications in adults with acute urinary retention. Materials and Methods: We searched the Cochrane Library, EMBASE, Google Scholar, and PubMed databases for articles published from the database inception to 31 August 2021. Studies that compared the effects and complication rates of rapid and gradual urinary decompression in adults with acute urinary retention were included. The primary outcome was post-decompression hematuria, while the secondary outcome was circulatory collapse. Meta-analyses were conducted using random effects models. Sensitivity analyses, tests for publication bias, and trial sequential analyses were conducted. The PROSPERO registration number is CRD42021233457. Results: Overall, four articles were included in the comprehensive analysis, and 435 participants met all the eligibility criteria. In the primary meta-analysis of all four study groups, rapid urinary decompression did not increase the risk of post-decompression hematuria (RR = 0.91; 95% CI: 0.62 to 1.35; p = 0.642). The I2 statistic was 0.0% (p = 0.732), indicating no substantial heterogeneity. In the meta-analysis of randomized controlled studies, the result did not change (RR = 0.89; 95% CI: 0.31 to 2.52; p = 0.824). The Egger's test and Begg test (p = 0.339 and 0.497, respectively) indicated the absence of statistical evidence of publication bias. Leave-one-out sensitivity analysis was conducted and showed the pooled results were robust. In secondary outcome, there were no reported events of circulatory collapse in the current studies. Conclusions: The currently available data suggest that rapid urinary decompression is an effective and safe method with a complication rate similar to that of gradual decompression in an acute urinary retention population. Further large-scale randomized studies are required.

[PMID: 35628905 PMCID: PMC9146076 DOI: 10.3390/jcm11102778] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2022] [Revised: 05/06/2022] [Accepted: 05/11/2022] [Indexed: 01/27/2023] Open
Abstract
Background and Objectives: Systemic analgesics, including opioids, are commonly used for acute pain control in traumatic hip fracture patients in the emergency department (ED). However, their use is associated with high rates of adverse reactions in the geriatric population. As such, the aim of this study was to investigate the impact of lidocaine-based single-shot ultrasound-guided femoral nerve block (USFNB) on the standard care for acute pain management in geriatric patients with traumatic hip fracture in the ED. Methods: This retrospective, single-center, observational study included adult patients aged ≥60 years presenting with acute traumatic hip fracture in the ED between 1 January 2017 and 31 December 2020. The primary outcome measure was the difference in the amount of opioid use, in terms of morphine milligram equivalents (MME), between lidocaine-based single-shot USFNB and standard care groups. The obtained data were evaluated through a time-to-event analysis (time to meaningful pain relief), a time course analysis, and a multivariable analysis. Results: Overall, 607 adult patients (USFNB group, 66; standard care group, 541) were included in the study. The patients in the USFNB group required 80% less MME than those in the standard care group (0.52 ± 1.47 vs. 2.57 ± 2.53, p < 0.001). The multivariable Cox proportional hazards regression models showed that patients who received USFNB achieved meaningful pain relief 2.37-fold faster (hazard ratio (HR) = 2.37, 95% confidence intervals (CI) = 1.73−3.24, p < 0.001). Conclusions: In geriatric patients with hip fractures, a lidocaine-based single-shot USFNB can significantly reduce opioid consumption and provide more rapid and effective pain reduction.

Patient-physician communication in the emergency department in Taiwan: physicians’ perspectives. BMC Health Serv Res 2022; 22:152. [PMID: 35123459 PMCID: PMC8817560 DOI: 10.1186/s12913-022-07533-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Accepted: 01/24/2022] [Indexed: 11/14/2022] Open
Abstract
Background Effective patient-physician communication promotes trust and understanding between physicians and patients and reduces medical disputes. In this study, the Roter Interaction Analysis System was used to explore physician-patient communication behaviors in the emergency departments of Taiwanese hospitals. Method Data was collected from the dialogues between 8 emergency physicians and 54 patients through nonparticipant observation, and 675 pieces of data were quantitatively and qualitatively analyzed. Results The results showed that: 1. Emergency physicians’ communication behaviors are task-focused. They usually ask closed-ended questions to collect data to identify the symptoms quickly and provide medical treatment. 2. Socioemotion-oriented physician-patient communication behaviors are less common in the emergency department and only serve as an aid for health education and follow-up. Due to time constraints, it is difficult to establish relationships with patients and evoke their positivity. Conclusions It is suggested that future education programs on physician-patient communication in the emergency department should focus on strengthening physicians’ ability to communicate with patients in a more open way. They should adopt socioemotional-oriented communication skills, expressing respect and kindness, and allowing patients to briefly describe their symptoms and participate in the treatment process to achieve physician-patient consensus.

Abstract
There are several treatment options for localized prostate cancer with very similar outcome but vary in terms of technique and side effect profiles and risks. Considering the potential difficulty in choosing the best treatment, a patient decision aid (PDA) is used to help patients in their decision-making process. However, the use and applicability of PDA in a country in Asia Pacific region like Malaysia is still unknown. This study aims to evaluate the effectiveness of a PDA modified to the local context in improving patients' knowledge, decisional conflict, and preparation for decision making among men with localized prostate cancer. Sixty patients with localized prostate cancer were randomly assigned to control and intervention groups. A self-administered questionnaire, which evaluate the knowledge on prostate cancer (23 items), decisional conflict (10 items) and preparation for decision-making (10 items), was given to all participants at pre- and post-intervention. Data were analyzed using independent T test and paired T test. The intervention group showed significant improvement in knowledge (p = 0.02) and decisional conflict (p = 0.01) from baseline. However, when compared between the control and intervention groups, there were no significant differences at baseline and post-intervention on knowledge, decisional conflict and preparation for decision-making. A PDA on treatment options of localized prostate cancer modified to the local context in an Asia Pacific country improved patients' knowledge and decisional conflict but did not have significant impact on the preparation for decision-making. The study was also registered under the Australian New Zealand Clinical Trials Registry (ANZCTR), ACTRN12614000668606 registered on 25/06/2014.

Abstract
BACKGROUND/AIMS To assess changes in optic nerve sheath diameter (ONSD) at high altitude and in acute mountain sickness (AMS). METHODS Cochrane Library, EMBASE, Google Scholar and PubMed were searched for articles published from their inception to 31st of July 2020. Outcome measures were mean changes of ONSD at high altitude and difference in ONSD change between subjects with and without AMS. Meta-regressions were conducted to investigate the relation of ONSD change to altitude and time spent at that altitude. RESULTS Eight studies with 248 participants comparing ONSD from sea level to high altitude, and five studies with 454 participants comparing subjects with or without AMS, were included. ONSD increased by 0.14 mm per 1000 m after adjustment for time (95% CI: 0.10 to 0.18; p<0.01). Restricted cubic spline regression revealed an almost linear relation between ONSD change and time within 2 days. ONSD was greater in subjects with AMS (mean difference=0.47; 95% CI: 0.14 to 0.80; p=0.01; I2=89.4%). CONCLUSION Our analysis shows that ONSD changes correlate with altitude and tend to increase in subjects with AMS. Small study number and high heterogeneity are the limitations of our study. Further large prospective studies are required to verify our findings.

Abstract
Background To carry out competency-based medical education, this study has established five Entrustable Professional Activities (EPAs) for the emergency medicine residents. The EPAs involve substantial data collection, which requires integration and analysis for the fi nal interpretation. Therefore, the "EPAs-Based e-Portfolio System" has been developed for assisting users to perform ad-hoc assessment, recording of a discussion, teaching, and feedback. The purpose of this study is to examine, from the perspective of the Technology Acceptance Model, residents and clinicians' experience of the EPAs-Based e-Portfolio System, including the use of functions such as recording, feedback, and assessment, as well as the impact thereof. Methods This study uses in-depth interviews as a means of data collection. The interviewees are from emergency medicine training hospitals in north, central, and south Taiwan-11 resident doctors and nine medical teachers. Results The interviewees agree that (1) the EPAs-based e-Portfolio System provides users with a complete learning trajectory record through cloudization and ease of use; (2) it can assist users to gain feedback, case review, and reflection; (3) information on user status can reflect their learning progress, competencies, and performance; (4) other potential functions that can be added include shortcut keys, initiation of assessment sheets by a learner, feedback to teacher's comment, and voice/picture input. Conclusions The results of this study indicate that the easier a system is for users to use, the more helpful they will consider it and the more positive they will be, which will then translate into greater willingness to use the system and higher frequency of actual use. The system can authentically reflect trainees' professional capabilities if the ad-hoc teaching and feedback in the clinical setting connect strongly with the online assessment and recording.

Abstract
Ketamine related urinary tract complications were first reported in Hong Kong since 2007. The current case report describes a 37 years old male with long history of ketamine abuse, renal impairment, hypertension and HCV hepatitis, presented to us with insidious onset of painful scrotal swelling post bilateral nephrectomy, prostate and seminal vesicle preserving cystectomy. Radiological imaging and intraoperative finding revealed that it was a large spermatocele with urethroscrotal fistula, which was likely due to urethra stricture. The review of literature showed no guidelines for treatment, a symptoms based and multidisciplinary team approach is recommended.

Energy transfer from adipocytes to cancer cells in breast cancer. Neoplasma 2020; 67:992-1001.

Abstract
Limitations of the current therapeutic approach have raised the need for a novel therapeutic agent in breast cancer. Recently, interest in drugs targeting the tumor microenvironment (TME) had drawn attention in the treatment of breast cancer. Furthermore, recent studies have suggested the role of adipocytes, which are part of the TME, in tumor initiation, growth, and metastasis. In this study, we investigated the metabolic interaction between adipocytes and breast cancer cells and its potential as a new therapeutic target in breast cancer. Breast cancer cell lines and human breast cancer tissue samples were evaluated. Compared to cancer cells cultured alone, or the control group, those co-cultured with adipocytes showed lipid transfer from adipocytes to cancer cells and it was different according to the molecular subtype of breast cancer. Breast cancer cells affected the lipolysis of adipocytes and adipocytes affected the β-oxidation of breast cancer cells. The key molecule of the process was fatty acid binding protein 4 (FABP4), which is combined with free fatty acid (FFA) and supports its migration to cancer cells. When FABP4 was suppressed, lipid transfer between adipocytes and cancer cells, lipolysis of adipocytes, and β-oxidation of breast cancer cells were reduced. Furthermore, the expression of lipid metabolism-related proteins and lipolysis-related proteins in breast cancer with adipose stroma showed significantly different expression according to the region of breast cancer tissue. Taken together, we demonstrated the metabolic interaction between adipocytes and breast cancer cells. Breast cancer cells increase the lipolysis in adipocytes and produce a fatty acid, and fatty acid enters into cancer cells. Also, adipocytes contribute to the survival and growth of cancer cells through increased mitochondrial β-oxidation by using fatty acid from adipocytes. The key molecule of the process is FABP4 and when FABP4 is suppressed, the metabolic interaction is reduced, suggesting its role as a potential therapeutic target.

Abstract
The emergence of the COVID-19 pandemic has severely affected medical treatment protocols throughout the world. While the pandemic does not affect hand surgeons at first glance, they have a role to play. The purpose of this study was to describe the different measures that have been put in place in response to the COVID-19 pandemic by hand surgeons throughout the world. The survey comprised 47 surgeons working in 34 countries who responded to an online questionnaire. We found that the protocols varied in terms of visitors, health professionals in the operating room, patient waiting areas, wards and emergency rooms. Based on these preliminary findings, an international consensus on hand surgery practices for the current viral pandemic, and future ones, needs to be built rapidly.

Abstract
An internal consistency test of the calculation of coincidence-summing correction factors FC for volume sources is presented. The test is based on exact equations relating the values of FC calculated for three ideal measurement configurations. The test is applied to a number of 33 sets of FC values sent by 21 teams. Most sets passed the test, but not the results obtained using the quasi-point source approximation; in the latter case the test qualitatively indicated the magnitude of the bias of FC.

Abstract
INTRODUCTION Robust assessment is a crucial component in Advanced Cardiac Life Support (ACLS) training to determine whether participants have achieved learning objectives with little or no variation in their overall outcomes. This study aimed to evaluate resuscitation performance by real-time logs. We hypothesised that instructors may not be able to evaluate time-sensitive parameters, namely, chest compression fraction, time to initiating chest compression and time to initiating defibrillation accurately in a subjective manner. METHODS Video records and formal checklist-based test results of Megacode scenarios for the ACLS certification examination at several hospitals in Taipei were examined. For the study interest, three time-sensitive parameters were measured via video review assisted by a mobile phone application, and were used for evaluation. We evaluated if the pass/fail results made by instructors via checklists were correlated with these parameters. RESULTS A total of 185 Megacode scenarios were eligible for the final analysis. Among the three parameters, good chest compression fraction was statistically significant with a higher OR of passing (OR=3.65; 95% CI 1.36 to 9.91; p=0.01). In 112 participants with one parameter that did not meet the criteria, 25 were graded as fail, making the specificity 22.3% (95% CI 15.0% to 31.2%). CONCLUSIONS Visual observation of cardiopulmonary resuscitation performance is not accurate when evaluating time-sensitive parameters. Objective results should be offered for training outcome evaluation, and also for feedback to participants.

Abstract
OBJECTIVE Trials of ginkgo biloba extract (GBE) for the prevention of acute mountain sickness (AMS) have been published since 1996. Because of their conflicting results, the efficacy of GBE remains unclear. We performed a systematic review and meta-analysis to assess whether GBE prevents AMS. METHODS The Cochrane Library, EMBASE, Google Scholar and PubMed databases were searched for articles published up to 20 May 2017. Only randomised controlled trials were included. AMS was defined as an Environmental Symptom Questionnaire Acute Mountain Sickness-Cerebral score ≥0.7 or Lake Louise Score ≥3 with headache. The main outcome measure was the relative risk (RR) of AMS in participants receiving GBE for prophylaxis. Meta-analyses were conducted using random-effects models. Sensitivity analyses, subgroup analyses and tests for publication bias were conducted. RESULTS Seven study groups in six published articles met all eligibility criteria, including the article published by Leadbetter et al, where two randomised controlled trials were conducted. Overall, 451 participants were enrolled. In the primary meta-analysis of all seven study groups, GBE showed trend of AMS prophylaxis, but it is not statistically significant (RR=0.68; 95% CI 0.45 to 1.04; p=0.08). The I2 statistic was 58.7% (p=0.02), indicating substantial heterogeneity. The pooled risk difference (RD) revealed a significant risk reduction in participants who use GBE (RD=-25%; 95% CI, from a reduction of 45% to 6%; p=0.011) The results of subgroup analyses of studies with low risk of bias, low starting altitude (<2500 m), number of treatment days before ascending and dosage of GBE are not statistically significant. CONCLUSION The currently available data suggest that although GBE may tend towards AMS prophylaxis, there are not enough data to show the statistically significant effect of GBE on preventing AMS. Further large randomised controlled studies are warranted.

Abstract
Objective: In addition to high-quality chest compression, parameters of resuscitation efficiency such as early chest compression, early defibrillation, and decreased hands-off time are also vital in the Advanced Cardiac Life Support (ACLS) protocol. However, because of limited time and equipment in ACLS courses, efficiency of performance is difficult to evaluate. Materials and Methods: A free, easy-to-use iOS and Android app (CodeTracer®) was developed for real-time recording of cardiopulmonary resuscitation (CPR) performance. Interventions performed during resuscitation were set up as buttons. When the simulated scenario in the ACLS course began, instructors recorded every intervention and the team performed by pushing the appropriate buttons. When the scenario ended, the CodeTracer® automatically computed parameters, including the percentage of no-flow time, time to initiating CPR, and time to initiating defibrillation and also generated a graphic log for later discussion. Results: A total of 76 resuscitation episodes were recorded, 27 in the practice scenarios and 49 in the final Megacode simulations. After the course, the average percentage of no-flow time decreased 5.79%, time to initiating CPR decreased 3.05 s, and time to initiating defibrillation decreased up to 20.27 s. Of note, physicians as leaders seem to have better performance after the ACLS course than before, but the results were insignificant except for the percentage of no-flow time. Conclusions: CodeTracer® can record and calculate objective parameters for resuscitation performance in ACLS courses and can assist instructors in disseminating important concepts to participants. It can be a useful tool in ACLS courses.

Validity of the intra-operative measurement of stem anteversion and factors for the erroneous estimation in cementless total hip arthroplasty using postero-lateral approach. Orthop Traumatol Surg Res 2018; 104:341-346. [PMID: 29458202 DOI: 10.1016/j.otsr.2017.11.023] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2017] [Revised: 11/07/2017] [Accepted: 11/23/2017] [Indexed: 02/02/2023]
Abstract
BACKGROUND Intra-operative estimation of stem anteversion in total hip arthroplasty (THA) using postero-lateral approach is made by the surgeon's visual assessment, using the tibia as a guide, with the assumption that tibial axis is vertical to the trans-epicondylar axis. However, the accuracy of the intra-operative estimation has rarely been verified with postoperative CT-scans, with controversies regarding these measurements particularly in case of knee osteoarthritis. Therefore we performed a prospective study to: (1) determine the accuracy of the intra-operative measurement and (2) investigate factors affecting the discrepancy between the surgeon's estimation and the real stem anteversion. HYPOTHESIS Intra-operative estimation of stem anteversion correlated with the real stem anteversion on CT-scan. PATIENTS AND METHODS Sixty-seven THAs using cementless straight stems (65 patients) without ipsilateral total knee arthroplasty were prospectively evaluated to compare the intra-operative measurement of stem anteversion with the real stem anteversion on computed tomography (CT) scans. There were 33 men and 34 women with a mean age of 59.7years (range, 27-84years) at the time of surgery. Age, tibia plateau angle, native femoral anteversion, femoro-tibial angle, body mass index, operative site, gender, coronal and sagittal tilt of the stem, stem type, ipsilateral knee osteoarthritis, and preoperative diagnosis were analyzed to evaluate the factors affecting the discrepancy between the intra-operative and CT measurements. RESULTS The intra-operative estimation (mean, 21.5°±8.5°; range, 5.0°-39.0°) was greater than the CT measurement (mean, 19.5°±8.7°; range, 4.5°-38.5°) by 2.0°. The mean absolute value of discrepancy was 4.5°. The correlation coefficient between intra-operative and CT measurements was 0.837. The femoro-tibial angle was associated with the discrepancy between the two measurements. In the presence of genu varum deformity, the intra-operative measurement underestimated the stem anteversion. DISCUSSION Although intra-operative estimation of stem anteversion was slightly greater than the real stem anteversion, there was an excellent correlation between the two. The femoro-tibial angle should be considered to optimize the stem anteversion during cementless THA using postero-lateral approach. LEVEL OF EVIDENCE Level III, prospective case control study.

Abstract
Several studies have reported that intestinal microbial colonisation patterns differ between non-allergic and allergic infants. However, the microbial signature underlying the pathogenesis of allergies remains unclear. We aim to gain insight into the development of the intestinal microbiota of healthy infants and infants who develop allergy in early life, and identify potential microbiota biomarkers of later allergic disease. Using a case-control design in a Chinese sub-cohort of a Singaporean birth cohort (GUSTO), we utilised 16S rRNA gene sequencing to assess intestinal microbial composition and diversity of 21 allergic and 18 healthy infants at 3 weeks, 3 months and 6 months of age, and correlated the microbiota with allergy at ages 18 and 36 months. Pronounced differences in intestinal microbiota composition between allergic and healthy infants were observed at 3 months of age. The intestine of healthy infants was colonised with higher abundance of commensal Bifidobacterium. Conversely, Klebsiella, an opportunistic pathogen, was significantly enriched in the allergic infants. Interestingly, infants with a high Klebsiella/Bifidobacterium (K/B) ratio (above the population median K/B ratio) at age 3 months had an odds ratio of developing allergy by 3 years of age of 9.00 (95% confidence interval 1.46-55.50) compared to those with low K/B ratio. This study demonstrated a relationship between the ratio of genera Klebsiella and Bifidobacterium during early infancy and development of paediatric allergy in childhood. Our study postulates that an elevated K/B ratio in early infancy could be a potential indicator of an increased risk of allergy development. This line of research might enable future intervention strategies in early life to prevent or treat allergy. Our study provides new insights into microbial signatures associated with childhood allergy, in particular, suggests that an elevated K/B ratio could be a potential early-life microbiota biomarker of allergic disease.

The synthetic molecules YK51 and YK73 attenuate replication of dengue virus serotype 2. Trop Biomed 2017; 34:270-283.

Abstract
Dengue virus infection has been posing alarming economic and social burden on affected nations. It is estimated that 50-100 million dengue infections occur annually with over 2.5 billion people at risk for endemic transmission. In the effort to develop effective antiviral agents, we previously reported potential antiviral activities from selected array of natural products and compounds against dengue virus serotype 2 (DV2). In this study, we report the synthesis of two efficacious novel compounds, YK51 and YK73, and their activities against DV2 replication. Both compounds were chemically synthesised from nicotinic acid using a modified method for the synthesis of dihydropyridine. The products were tested with cell-based assays against DV2 followed by a serine protease assay. As a result, both YK51 and YK73 exhibited intriguing antiviral properties with EC50 of 3.2 and 2.4 µM, respectively. In addition, YK51 and YK73 were found to attenuate the synthesis of intracellular viral RNA and protect the switching of non-classic mechanism of protein translation. These compounds demonstrated inhibitory properties toward the activity of DV2 serine protease in a dose dependent manner. These findings demonstrate that both YK51 and YK73 serve as DV2 serine protease inhibitors that abrogate viral RNA synthesis and translation. Further investigation on these compounds to corroborate its therapeutic properties towards dengue is warranted.

Association between Chronic Kidney Disease and Risk of Cataract: A Nationwide Retrospective Cohort Study. Am J Nephrol 2017; 45:524-531. [PMID: 28528337 DOI: 10.1159/000475555] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2016] [Accepted: 03/12/2017] [Indexed: 11/19/2022]
Abstract
BACKGROUND Previous studies have established a relationship between chronic kidney disease (CKD) and cataract, but the relationship between the severity of renal impairment and risk of cataract is uncertain. This study investigates the relationship between the severity of renal disease and cataract in a nationwide sample from Taiwan. METHODS The cohort from 1-million National Health Insurance beneficiaries from Taiwan was retrospectively analyzed. All adult beneficiaries were followed from January 1, 2005 until December 31, 2013, to identify patients who underwent cataract surgeries. On the basis of the ambulatory care records, those diagnosed with CKD (ICD-9-CM code: 585) during the follow-up period were enrolled as CKD patients after careful evaluation. Each patient with CKD was age- and gender-matched with 4 individuals who did not have CKD. Cox regression models were applied to compare the hazard of cataract surgery in individuals with and without CKD. Subgroup analysis was used to compare patients with end-stage renal disease (ESRD) with age- and gender-matched non-CKD individuals. ESRD was defined by CKD patients who need regular renal replacement therapy. The same method was applied to evaluate hazard ratios (HRs). RESULTS After age and gender matching, there were 11,881 patients in the CKD group and 47,524 in the non-CKD group. After control for possible confounding, the adjusted HR (aHR) of cataract was 1.84 (95% CI 1.73-1.95) for the CKD group. Subgroup analysis of patients with ESRD (n = 3,209) and non-CKD individuals (n = 12,836), with matching done on the basis of age and gender, indicated an aHR of cataract was 2.33 (95% CI 2.10-2.59) for the ESRD group. CONCLUSIONS This study indicates a relationship between CKD and cataract, and suggests that the risk for cataract increases with the severity of renal impairment.

ICSH recommendations for modified and alternate methods measuring the erythrocyte sedimentation rate. Int J Lab Hematol 2017; 39:448-457. [PMID: 28497537 DOI: 10.1111/ijlh.12693] [Citation(s) in RCA: 46] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2016] [Accepted: 04/03/2017] [Indexed: 11/30/2022]
Abstract
INTRODUCTION The gold standard for the determination of the erythrocyte sedimentation rate (ESR) is the Westergren method. Other methods to measure the ESR have become available. They range from modest modifications of the Westergren method to very different methodologies. The ICSH therefore established a Working Group to investigate these new approaches and compile recommendations for their validation and verification. METHODS A panel of six experts in laboratory hematology examined the peer-reviewed literature and EQA surveys from over 6000 laboratories on four continents performing ESR testing. This information was used to create lists of ESR instrument manufacturers and their methods. RESULTS Only 28% of laboratories surveyed used the unmodified Westergren method, while 72% of sites used modified or alternate methods. Results obtained with the new instruments could differ from results obtained with the Westergren method by up to 142%. Different non-Westergren methods showed differences from each other of up to 42%. The new methods were often significantly faster, safer, and less labor-intensive. They reduced costs and often used standard EDTA tubes, eliminating the need for a dedicated ESR tube. CONCLUSION Based on the consensus of the Working Group, recommendations for manufacturers for the validation of new ESR methods were developed. In addition, a list of recommendations for laboratories that are moving to modified or alternate methods was compiled, addressing instrument performance verification and communications of results to clinical users.

Abstract
OBJECTIVES To evaluate the prevalence of affective disorders and identify their associated factors among Chinese mothers of preschool children diagnosed with autism spectrum disorders. METHODS This cross-sectional study was conducted at the Autism Spectrum Disorders Multidisciplinary Clinic of the United Christian Hospital from August 2012 to June 2013. All mothers of a consecutive series of preschool children diagnosed with autism spectrum disorders at their first visit to the clinic were recruited. Information regarding the child-related, maternal, and environmental factors was collected. Psychiatric diagnoses were made according to the Chinese-Bilingual Structured Clinical Interview for DSM-IV Axis I Disorders. Independent factors associated with maternal affective disorders were determined by univariate and multivariate analyses. RESULTS Of the 121 subjects, the point prevalence of affective disorders as a group was 29.8%. The point prevalence of major depressive disorders, adjustment disorders, anxiety disorders, and bipolar affective disorders was 14.9%, 10.7%, 3.3% and 0.8%, respectively. A higher level of disruptive and self-absorbed behaviours in the children (as assessed by the Developmental Behaviour Checklist), a higher level of affiliate stigma (as assessed by 22-item Affiliate Stigma Scale), and a history of psychiatric disorders were independently associated with current affective disorders. CONCLUSION Psychiatric disorders, predominantly affective disorders, are common among Chinese mothers of preschool children with autism spectrum disorders. Identification of independent factors associated with maternal affective disorders can aid in the early detection of cases and planning of early intervention programmes to address both child and maternal psychological needs.

Abstract
The effects of pre-operative angiotensin-converting enzyme inhibitor (ACEI) treatment on haemodynamic status and vasoconstrictor requirements during off-pump coronary artery bypass surgery (OPCAB) were studied. Eighty patients selected for OPCAB were divided into those who had been treated with ACEIs for 4 weeks or more pre-operatively (ACEI group) (n = 43) and those who had not been treated with ACEIs (control group) (n = 37). Noradrenaline was infused during the operation when the mean systemic arterial pressure (SAP) fell below 60 mmHg. No significant differences in the haemodynamic parameters measured were detected between the two groups, except for cardiac output, which was found to be significantly greater in the control group. During anastomosis of the obtuse marginal branch of the left circumflex artery (OM), a significantly larger amount of noradrenaline was required by the ACEI group compared with the control group. In conclusion, pre-operative treatment with ACEIs significantly increased the amount of vasoconstrictor necessary to maintain the target SAP during OM anastomosis during OPCAB.

Abstract
INTRODUCTION Meta-analyses of genetic association studies are affected by biases and quality shortcomings of the individual studies. We previously developed and validated a risk of bias tool for use in systematic reviews of genetic association studies. The present study describes a larger empirical evaluation of the Q-Genie tool. METHODS AND ANALYSIS MEDLINE, Embase, Global Health and the Human Genome Epidemiology Network will be searched for published meta-analyses of genetic association studies. Twelve reviewers in pairs will apply the Q-Genie tool to all studies in included meta-analyses. The Q-Genie will then be evaluated on its ability to (i) increase precision after exclusion of low quality studies, (ii) decrease heterogeneity after exclusion of low quality studies and (iii) good agreement with experts on quality rating by Q-Genie. A qualitative assessment of the tool will also be conducted using structured questionnaires. DISCUSSION This systematic review will quantitatively and qualitatively assess the Q-Genie's ability to identify poor quality genetic association studies. This information will inform the selection of studies for inclusion in meta-analyses, conduct sensitivity analyses and perform metaregression. Results of this study will strengthen our confidence in estimates of the effect of a gene on an outcome from meta-analyses, ultimately bringing us closer to deliver on the promise of personalised medicine. ETHICS AND DISSEMINATION An updated Q-Genie tool will be made available from the Population Genomics Program website and the results will be submitted for a peer-reviewed publication.
