Abstract
Anthropogenic hybridization, or higher and non-natural rates of gene flow directly and indirectly induced by human activities, is considered a significant threat to biodiversity. The primary concern for conservation is the potential for genomic extinction and loss of adaptiveness for native species due to the extensive introgression of non-native genes. To alleviate or reverse trends for such scenarios requires the direct integration of genomic data within a model framework for effective management. Towards this end, we developed the simRestore R program as a decision-making tool that integrates ecological and genomic information to simulate ancestry outcomes from optimized conservation strategies. In short, the program optimizes supplementation and removal strategies across generations until a set native genetic threshold is reached within the studied population. Importantly, in addition to helping with initial decision-making, simulations can be updated with the outcomes of ongoing efforts, allowing for the adaptive management of populations. After demonstrating functionality, we apply and optimize among actionable management strategies for the endangered Hawaiian duck for which the current primary threat is genetic extinction through ongoing anthropogenic hybridization with feral mallards. Simulations demonstrate that supplemental and removal efforts can be strategically tailored to move the genetic ancestry of Hawaii's hybrid populations towards Hawaiian duck without the need to completely start over. Further, we discuss ecological parameter sensitivity, including which factors are most important to ensure genetic outcomes (i.e. number of offspring). Finally, to facilitate use, the program is also available online as a Shiny Web application.

Abstract
Incomplete milking (IM) is one way of mitigating the negative energy balance (NEB) that is characteristic for early lactation and may increase the risk for disease. Our objectives were to test the effects of IM in early lactation on energy balance (EB), metabolic status, udder health, and subsequent performance. To facilitate the practical application, an automated system was used to remove the milking clusters once a predefined amount of milk is withdrawn. Forty-six Holstein cows were equally allocated to either the treatment (TRT, starting on 8 d in milk) or the control group (CON; conventional cluster removal at milk flow rate <0.3 kg/min). Milk removal in the TRT group was limited to the individual cow's milk yield 1 d before IM started and held constant for 14 d. Thereafter, all cows were conventionally milked and records related to EB, performance, and udder health were continued up to 15 wk of lactation. During the 14 d of IM, on average 11.1% less milk was obtained from the TRT cows than from the CON cows. Thereafter, milk yield increased in the TRT group, eliminating the group difference throughout the remaining observation period until wk 15 of lactation. The TRT cows tended to have less dry matter intake and also water intake than the CON cows. The extent of the NEB and the circulating concentrations of fatty acids, β-hydroxybutyrate, insulin-like growth factor-1, and leptin mostly did not differ between the groups. The IM did not affect body condition. Udder health was maintained over the entire observation period in all cows. Our results demonstrate the applicability of the automated cluster removal for limiting milk withdrawal to a defined amount in early lactation. However, it remains to be determined whether the absent effect on energy metabolism was due to the relatively stable energy status of the cows or to the relatively mild IM setting used herein.

Abstract
OBJECTIVE To assess management strategies for pediatric patients with the challenging combination of congenital heart diseases (CHDs) and airway anomalies. STUDY DESIGN Patients diagnosed with CHD and airway anomalies in the Pediatric Cardiac Surgery Centre of Fuwai Hospital from January 2016 to December 2020 were included in this retrospective study. Patients were divided into three groups based on different management, including the conservative group, the slide group (slide tracheoplasty), and the suspension group (suspension with external stenting). Patients' data and computed tomography measurements from medical records were reviewed. RESULTS A total of 139 patients were included in the cohort; 107 had conservative airway treatment (conservative group), 15 had slide tracheoplasty (slide group), and 17 had tracheal suspension operation (suspension group). The top three associated intracardiac anomalies were ventricular septal defect (n = 34, 24%), pulmonary artery sling (n = 22, 16%), and tetralogy of Fallot (n = 15, 11%). Compared with patients with conservative airway management (100 minutes [median], 62-152 [IQR]), the extra airway procedure prolonged cardiopulmonary bypass duration, with 202 minutes (IQR, 119-220) for the slide group and 150 minutes (IQR, 125-161) for the suspension group. Patients who underwent slide tracheoplasty required prolonged mechanical ventilation (129 minutes [median], 56-328 [IQR]). Of the total cohort, 6 in-hospital deaths, all in the conservative group, and 8 mid-to long-term deaths, with 6 in the conservative group, occurred. CONCLUSIONS Both conservative and surgical management of CHD patients with airway anomalies have promising outcomes. Extra tracheobronchial procedures, especially the slide tracheoplasty, significantly prolonged cardiopulmonary bypass duration. Based on multidisciplinary team assessment, individualized management strategies should be developed for these patients.

Abstract
Background and aims Familial hypercholesterolemia (FH) is becoming a global burden. However, it remains underdiagnosed and undertreated worldwide. This study aimed to observe the screening rate of FH patients and department distribution among hospitalized patients using different diagnostic criteria. Methods A total of 45,410 inpatients with LDL-C ≥3.5 mmol/L between 2008 and 2019 were included from The Second Affiliated Hospital of Nanchang University. Inpatients are diagnosed and divided into groups by Dutch Lipid Clinic Network (DLCN) criteria, Chinese-modified DLCN criteria and Chinese expert consensus (CEC) criteria. Results There were 172, 1,076 and 115 inpatients included in the DLCN group, Chinese-modified DLCN group and CEC group, respectively (screening rates: 0.38%, 2.37% and 0.25%). These FH patients had a very high risk of atherosclerotic cardiovascular disease (ASCVD) (55.7%-74.4%), especially in the DLCN group and CEC group (70.4%-74.4%). More than half of the patients were in the Department of Cardiology, and other high-risk departments included Neurology, Nephrology, Vascular Surgery, Otolaryngology & Head Neck Surgery and Traditional Chinese Medicine (24.35%-31.51%). Overall, hypertension, coronary heart disease, carotid arteriosclerosis, hepatic cyst, arrhythmia, and nonalcoholic fatty liver disease were common accompanying diseases with FH. Conclusions It is necessary to establish appropriate diagnostic criteria and more positive treatment strategies for the FH inpatient population. In addition, promoting awareness of FH among doctors from other departments is also necessary. Therefore, developing a comprehensive management strategy for FH disease is very important.

Abstract
Introduction Microorganisms play an important role in the multifunctionality of soil ecosystems. Soil microbial diversity and functions have a great impact on plant growth and development. The interactions between tea trees and soil microbiota can be linked with planting patterns and management strategies, whose effects on soil microbial community structure and metabolites are still unclear. Methods Here we used amplicon sequencing and metabolomic analysis to investigate the differences in soil microbial composition and metabolites among three tea production systems: organic, non-organic, and intercropping. Results We detected significant differences among the three systems and found that Firmicutes, Proteobacteria, Acidobacteriota, Actinobacteriota and Chloroflexi were the main bacteria in the three soil groups, although they varied in relative abundance. Acidobacteria bacterium increased significantly in the organic and intercropping groups. For fungi, Ascomycota and Basidiomycota were the main differential fungal phyla. Fungi alpha-diversity in the non-organic group was significantly higher than that in the other two groups, and was correlated with multiple soil physical and chemical factors. Moreover, network analysis showed that bacteria and fungi were strongly correlated. The changes in soil microorganisms caused by management and planting patterns may affect soil quality through corresponding changes in metabolites. Metabolomic analysis showed differences in metabolite composition among different groups. It was also found that the arachidonic acid metabolic pathway was affected by changes in soil microorganisms, and may further affect soil quality in an essential manner. Discussion Planting patterns and management strategies may significantly affect soil microorganisms and therefore metabolites. Changes in soil microorganisms, especially in fungi, may alter soil quality by affecting soil physicochemical properties and metabolites. This study will provide new insights into soil quality monitoring from a microbiological perspective.

Abstract
Introduction The incidence of hospital-acquired pneumonia (HAP) is high in the medical setting for mental disorders. To date, effective measurements for preventing HAP in hospitalized mental disorder patients are unavailable. Methods This study was conducted at the Large-Scale Mental Health Center of Renmin Hospital of Wuhan University (Wuhan, China) in two phases: baseline phase (January 2017-December 2019) and intervention phase (May 2020-April 2022). In the intervention phase, the HAP bundle management strategy was implemented in the Mental Health Center, and the data on HAP were collected continuously for analysis. Results A total of 18,795 and 9,618 patients were included in the baseline and intervention phases, respectively. The age, gender, ward admitted to, type of mental disorder, and Charlson comorbidity index did not differ significantly. After intervention, the rate of HAP occurrence decreased from 0.95 to 0.52% (P < 0.001). Specifically, the HAP rate decreased from 1.70 to 0.95% (P = 0.007) in the closed ward and from 0.63 to 0.35% (P = 0.009) in the open ward. The HAP rate in the subgroups was higher in patients with schizophrenia spectrum disorders (1.66 vs. 0.74%) and organic mental disorders (4.92 vs. 1.41%), and in those ≥65 years old (2.82 vs. 1.11%) but decreased significantly after intervention (all P < 0.05). Conclusion The implementation of the HAP bundle management strategy reduced the occurrence of HAP in hospitalized patients with mental disorders.

Abstract
Developing in a limited space, rare tumors located at the nose and paranasal sinuses are sometimes difficult to diagnose due to their modest clinical presentation, which is uncorrelated with anatomopathological diversity. This limits the preoperative diagnosis without added immune histochemical study; for that reason, we present our experience with these tumors with the intention of raising awareness. The patient included in our study was investigated by our department through clinical and endoscopic examination, imaging investigations, and an anatomic-pathological study. The selected patient gave consent for participation and inclusion in this research study in compliance with the 1964 Declaration of Helsinki.

Abstract
Hypoxemia is 1 of the most common complications in the patients with acute Type A aortic dissection (ATAAD). This study aimed to summarize the risk factors, management strategies and long-term prognosis for postoperative hypoxemia in ATAAD patients. Baseline characteristics and clinical data of all the patients were collected. Patients were divided into 2 groups according to the PaO2/FiO2 after surgery: Hypoxemia group (n = 142) and Non-hypoxemia group (n = 68). The differences in gender, age, body mass index, operation time, cardiopulmonary bypass (CPB) time, aortic cross-clamping time, deep hypothermic circulatory arrest time, preoperative PaO2/FiO2, postoperative PaO2/FiO2, PaO2/FiO2 before extubating, time of mechanical ventilation, length of intensive care unit stay, length of hospital stay, in-hospital mortality, and overall mortality were compared between the 2 groups. The incidence of postoperative hypoxemia in this study was 67.6% (142/210). body mass index (26.4 ± 3.8 vs 24.4 ± 3.3kg/m2, P < .001) in the hypoxemia group were markedly higher and CPB time (196.3 ± 41.0 vs 181.0 ± 37.3 minutes, P = .010) in the hypoxemia group were significantly longer than those in the non-hypoxemia group. While preoperative PaO2/FiO2 (229.7 ± 91.4 vs 299.7 ± 101.2mmHg, P < .001) was significantly lower than those in the non-hypoxemia group. In the hypoxemia group, PaO2/FiO2 before extubating was significantly higher than that after operation, and the difference was significant. Logistic regression analysis showed that overweight (odds ratio [OR]: 1.113, P = .030), CPB time (OR: 1.009, P = .043) and preoperative PaO2/FiO2 (OR: 0.994, P = .001) were independent risk factors for postoperative hypoxemia. Further follow-up results showed no significant difference in long-term mortality between the 2 groups. Logistic regression analysis revealed that PaO2/FiO2 before extubating (OR: 0.985, P < .001), paraplegia (OR: 10.994, P = .019), acute renal failure (OR: 12.590, P < .001), re-operation (OR: 4.721, P = .014) and re-admission to intensive care unit (OR: 13.727, P = .001) were independent risk factors for long-term mortality. Our results showed that overweight and prolonged CPB time were risk factors for postoperative hypoxemia in ATAAD patients. While PaO2/FiO2 before extubating were independent risk factors for long-term mortality, indicating that active correction of hypoxemia and maintain a higher PaO2/FiO2 before extubating may help to improve the prognosis of the ATAAD patients.

Abstract
PURPOSE To investigate the demographics, clinical features, radiologic measurement, treatment, and outcomes of symptomatic spontaneous isolated superior mesenteric artery dissection (SISMAD) according to computed tomography (CT) classification. METHODS This retrospective study included 201 patients diagnosed with symptomatic SISMAD from November 2014 to December 2020. Symptomatic spontaneous isolated superior mesenteric artery dissection was categorized into four types based on CT images by Yun's angiographic classification. Their clinical characteristics, images features, treatment methods, and radiological outcomes were comparatively analyzed by CT angiographic types. RESULTS SISMADs were categorized into type I (13.9%) patent false lumen (FL) with both entry and re-entry; type IIa (37.3%), blind pouch of FL; type IIb (43.3%), thrombosed FL; and type III (5.5%), and the occlusion of superior mesenteric artery (SMA). Type IIb, the most common SISMAD, showed the largest true lumen (TL) residual diameter and the lowest percentage of TL stenosis. Type III positioned most proximally to SMA origin and had the maximum dissection length. Symptomatic spontaneous isolated superior mesenteric artery dissections underwent conservative (75.1%), endovascular (22.4%), and surgical (2.5%) treatment. Conservative treatment was more frequent in type I (85.7%) and type IIb (83.9%) than in type IIa (65.3%) and type III (45.5%). Endovascular intervention was more commonly utilized in type IIa (32.0%) and type III (36.4%) than in type I (14.3%) and type IIb (14.9%). Conservative patients achieved FL vanishment/shrinkage (57.8%), stabilization (26.6%), and enlargement (15.6%). After conservative treatment, type I showed angiographic FL stabilization; type IIa achieved FL shrinkage (48.1%), stabilization (22.2%), and enlargement (29.6%); type IIb exhibited FL vanishment/shrinkage (92.0%) and enlargement (8.0%). Cumulative rate of stent patency was 92.3% during 6-year follow-up. CONCLUSIONS Conservative management with close follow-up is initially provided especially for types I and IIb. Morphological stabilization is more frequent in type I of patent FL with entry and re-entry. False lumen vanishment or shrinkage was more likely to occur in type IIb due to the thrombus absorption. Endovascular intervention has excellent long-term in-stent patency and is predominantly utilized in types IIa and III. Blood flow sustained into a blind-ending FL causes the TL compression and stenosis in type IIa. Type III with the occlusion of SMA has the high risk of bowel ischemia. CLINICAL IMPACT According to Yun's angiographic classification of spontaneous isolated superior mesenteric artery dissection (SISMAD), type I (13.9%) has patent true and false lumen and the morphological pattern is maintained stable; type IIa (37.3%) possesses a patent blind-ending false lumen which might shrink, remain unchanged, or enlarge; and endovascular intervention is suggested when conservative treatment failed; type IIb (43.3%) recovers spontaneously due to the absorption of false lumen thrombus and conservative treatment is preferentially considered; type III (5.5%) with the occlusion of main trunk carries a high risk of bowel necrosis, early endovascular intervention is proposed, and open surgery might be necessary.

Abstract
The COVID-19 pandemic caused significant damage to global healthcare systems. Previous studies regarding COVID-19’s impact on outpatient numbers focused only on a specific department, lacking research data for multiple departments in general hospitals. We assessed differences in COVID-19’s impact on outpatient numbers for different departments to help hospital managers allocate outpatient doctor resources more effectively during the pandemic. We compared the outpatient numbers of 24 departments in a general hospital in Beijing in 2019 and 2020. We also examined an indicator not mentioned in previous studies, monthly departmental patient reservation rates. The results show that, compared with 2019, 2020 outpatient numbers decreased overall by 33.36%. Ten departments’ outpatient numbers decreased >33.36%; however, outpatient numbers increased in two departments. In 2020, the overall patient reservation rate in 24 departments was 82.22% of the 2019 reservation rate; the rates in 14 departments were <82.22%. Moreover, patient reservation rates varied across different months. Our research shows that COVID-19’s impact on different departments also varied. Additionally, our research suggests that well-known departments will be less affected by COVID-19, as will departments related to tumor treatment, where there may also be an increase in patient numbers. Patient reservation rates are an indicator worthy of attention. We suggest that hospital managers classify departments according to changes in outpatient numbers and patient reservation rates and adopt accurate, dynamic, and humanized management strategies to allocate outpatient doctor resources.

Abstract
The purpose of the study is to promote college students to actively respond to the national “Public Entrepreneurship and Mass Innovation” policies and calls, improve college students’ entrepreneurial enthusiasm and their entrepreneurial ability, and cultivate their good entrepreneurial psychological states. First, the relevant content of entrepreneurship psychology and causal attribution theory is displayed. Second, the questionnaire of college students’ entrepreneurship education is formulated and a questionnaire survey is conducted on University N based on the relevant content of entrepreneurship psychology. Subsequently, the management system of new venture A is taken as the research object to construct the management strategy of new ventures and simulate the implementation process. Finally, the questionnaire survey results of college students’ entrepreneurship education are analyzed and the corresponding entrepreneurship education path is formulated. Meanwhile, the implementation effect of the management strategy of new ventures is evaluated. After the questionnaire is sorted out, it is found that there are some problems in college students’ entrepreneurship education, such as weak awareness of entrepreneurship, insufficient publicity, outdated curriculum, and unqualified teachers. The reasons for these problems are the constraints of traditional concepts, insufficient attention, and incomplete system construction. Therefore, a plan is made for overall entrepreneurship education, the publicity of the concept of entrepreneurship education is strengthened, and the setting of entrepreneurship education curriculum and the ability of the teachers for entrepreneurship education are improved. Through the evaluation of the simulation implementation of a new enterprise management strategy, it is found that the new management strategy can achieve the expected effect. Therefore, this study provides some references for the development of college students’ entrepreneurship education and the management strategy of new ventures.

Abstract
BACKGROUND Despite multiple trials comparing rate with rhythm control, there is no consensus on optimal management of first-detected atrial fibrillation (AF). OBJECTIVE We analyzed current patterns of care for first-detected AF in the nationwide Get With The Guidelines®- Atrial Fibrillation Registry METHODS: Patients hospitalized with first-detected AF from 2013-19 were included and a descriptive analysis was performed comparing planned rate vs rhythm control. Multivariable logistic regression analysis was performed to identify predictors for choosing rhythm over rate control. RESULTS Among 86,759 patients with AF, 17.8% (15,473) had first-detected AF, 11,685 patients were included from 126 sites. Overall, 51.3% of patients were treated with rate control, and 48.7% with rhythm control at admission. Patients with planned rhythm control had a shorter length of stay and were more likely to be discharged home than a facility. A higher percentage of patients with planned rhythm control were discharged on anticoagulation compared to planned rate control (75.6% vs 70.9%) despite a higher underlying stroke risk in the rate control group (higher median CHA2DS2VASc-score (4; Q1-Q3 2-5 vs 3; Q1-Q32-4; p<0.001). While Hispanic ethnicity, Medicaid insurance, age >70 years, and liver disease decreased the likelihood of rhythm control, factors like heart failure, stroke, or prior bleeding diathesis had no association with the chosen treatment strategy. CONCLUSIONS Less than half of the patients with first-detected AF receive rhythm control at admission. Given recent trial results, further studies should assess the long-term impact of rhythm control on patients' symptoms and quality of life, cardiovascular morbidity, and mortality.

Abstract
New treatment modalities have been recently introduced in the management of ovarian cancer (OC). Herein, we sought to investigate their implementation in routine clinical practice and examine the real-world management of OC in Greece. EpOCa was a non-interventional, multicenter, retrospective study in patients with advanced epithelial OC. The primary outcome was to estimate the proportions of the different treatment regimens used per line of therapy, while progression-free survival (PFS) and overall survival (OS) were the key secondary endpoints. A total of 154 patients were enrolled in the study, among whom, 40% were tested for BRCA mutations and 30% were found to be positive. Nearly 90% of patients underwent debulking surgery at diagnosis, with few operations being also recorded upon relapse. Platinum-based chemotherapy (CT) was predominantly used in the first line with half of patients also receiving angiogenesis inhibitor (AI), while non-platinum-based CT was preferred in later lines. The median PFS was 18.2 and 8.8 months in the first- and second-line setting, respectively, whereas the median OS was approximately 50 months. Our study adds to the available, but limited, real world data on the management of ovarian cancer providing evidence regarding the applied treatment strategies and outcomes of patients in Greece.

Abstract
The empirical study reported here aims to improve the effectiveness of knowledge-based talent management in science and technology enterprises and promote the stable development of enterprises. First, the impact of entrepreneurs’ psychological cognition and personal characteristics on entrepreneurial activities is analyzed based on entrepreneurial psychology. Then, the theory of key competence is introduced to study the management mode of knowledge-based talents. The advantages of talents in enterprises are sorted out through constructing the key competency model to manage talents efficiently. The technology-based enterprise M is taken as an example for analysis by the key competence model to obtain 18 key capability indexes. Through the principal component analysis of 255 employees’ survey results, finally, four factors are extracted (business execution ability, team cooperation ability, strategic thinking ability, and management decision-making ability), which can reflect 68.92% of the total key competence. The average values of “business execution ability” and “team cooperation ability” in the first-level dimension of key competence index are 4.14 and 4.24, respectively, which can be regarded as the essential key competence. The investigation results of the academic qualifications of staff of M indicate that 6% of employees have a doctorate, 38% have a master’s degree, 37% have a Bachelor’s degree, and 19% have a junior college degree or below. Moreover, knowledge-based employees are basically satisfied with the organization and management of the company, but they are dissatisfied with the training mechanism and promotion mechanism. Therefore, enterprises should pay attention to the psychological needs of knowledge workers and the innovation of talent management. The research results are of significant value for science and technology enterprises to absorb and retain knowledge-based talents and promote the common development of enterprises and employees.

Abstract
Aims: This multi-centre study examined the effects of restricted availability of health-care services during the COVID-19 pandemic on treatment of coronary artery disease (CAD) in Finland. Methods: Data on referrals to cardiological units (n=81,008), emergency department (ED) visits (n=10,001) and hospitalisations (n=8654) for CAD were collected from three large Finnish hospitals, and incidences were calculated per 100,000 persons for the years 2017 through 2020. Year 2020 was compared to the reference years 2017-2019 by incidence rate ratios (IRR) with 95% confidence intervals (CI). Results: Referrals to cardiological units decreased after the onset of the pandemic in March to May (IRR=0.83, 95% CI 0.81-0.86). ED visits due to acute coronary syndrome decreased during the first months of the pandemic, with the overall annual incidence 2-14% lower than in the reference years. ED visits due to chronic CAD increased prominently during in April and May compared to the corresponding months in the reference years (IRR=1.49, 95% CI 1.23-1.81 in April; IRR=1.57, 95% CI 1.32-1.89 in May) and remained elevated until the end of 2020, with an increase in annual incidence of 17% (IRR=1.17, 95% CI 1.11-1.24). Conclusions: The first COVID-19 wave decreased ED visits due to acute coronary syndromes and increased those due to chronic CAD. The changes in referral and ED visit incidences during the second wave were rather modest.

Abstract
Background For patients with previously diagnosed dual primary tumors, it is usually difficult to determine the diagnosis and treatment of stage IV recurrence. The study was to explore the influences of 18F-fluoroestradiol positron emission tomography/computed tomography (18F-FES PET/CT) in the diagnosis of estrogen receptor (ER) positive breast cancer combined with other primary tumor with distant metastases. Methods Multidisciplinary team were organized to explore the definite clinical value of 18F-FES PET/CT in stage IV patients suffered from ER-positive breast cancer and another primary tumor synchronously or metachronously. Thirty-two female patients were retrospectively analyzed who underwent 18F-FES PET/CT scans in our center. Before and after reading 18F-FES reports, the team members from department of surgery, oncology and radiotherapy should make decisions of management strategy. Results Totally, the multidisciplinary team completed the management decision-making of the 32 patients before and after 18F-FES PET/CT scans. 87.5% (n=28) of the patients were considered to benefit from 18F-FES reports for diagnosis and treatment decisions. Out of the 28 patients, 7 patients (7/32, 21.9%) were considered to definitely change the management strategies while 12 patients (12/32, 37.5%) was instructive to develop management plans after the scan. The other 9 patients were suggested reassuring decision-making process by 18F-FES PET/CT. Conclusions 18F-FES PET/CT scans have clinical effects on diagnosis and treatment strategies of stage IV patients suffered from ER-positive breast cancer and another primary tumor.

Abstract
Choriocarcinoma is a malignant tumor associated with early vascular invasion and a high mortality. Ultra-high-risk choriocarcinoma, which was proposed in the International Federation of Gynecology and Obstetrics cancer report of 2018, has a higher risk of treatment failure and a worse prognosis than choriocarcinoma. We report a rare case of a 39-year-old female patient with ultra-high-risk choriocarcinoma (stage IV:20) with hemorrhage secondary to atraumatic splenic rupture as the initial sign. A satisfactory outcome was achieved through comprehensive treatment with surgery, chemotherapy, immunotherapy, and targeted therapy.

Abstract
Background In view of repeated COVID-19 outbreaks in most countries, clinical trials will continue to be conducted under outbreak prevention and control measures for the next few years. It is very significant to explore an optimal clinical trial management model during the outbreak period to provide reference and insight for other clinical trial centers worldwide. Objective The aim of this study was to explore the management strategies used to minimize the impact of the COVID-19 epidemic on oncology clinical trials. Methods We implemented a remote management model to maintain clinical trials conducted at Beijing Cancer Hospital, which realized remote project approval, remote initiation, remote visits, remote administration and remote monitoring to get through two COVID-19 outbreaks in the capital city from February to April and June to July 2020. The effectiveness of measures was evaluated as differences in rates of protocol compliance, participants lost to follow-up, participant withdrawal, disease progression, participant mortality, and detection of monitoring problems. Results During the late of the first outbreak, modifications were made in trial processing, participant management and quality control, which allowed the hospital to ensure the smooth conduct of 572 trials, with a protocol compliance rate of 85.24% for 3718 participants across both outbreaks. No COVID-19 infections were recorded among participants or trial staff, and no major procedural errors occurred between February and July 2020. These measures led to significantly higher rates of protocol compliance and significantly lower rates of loss to follow-up or withdrawal after the second outbreak than after the first, without affecting rates of disease progression or mortality. The hospital provided trial sponsors with a remote monitoring system in a timely manner, and 3820 trial issues were identified. Conclusions When public health emergencies occur, an optimal clinical trial model combining on-site and remote management could guarantee the health care and treatment needs of clinical trial participants, in which remote management plays a key role.

Abstract
Limited research has been conducted to identify how elder abuse (EA) can be managed and prevented. Interventions employed by a community agency multidisciplinary team across 164 EA cases were examined. Results identified the largest number (N = 369) and widest variety of EA interventions to date. Using content analysis, interventions with similar proximal goals were grouped into 30 intervention strategies to evaluate efficacy and 12 higher-order intervention categories to guide practice. Intervention outcomes were rated as positive, negative, neutral, could not implement, or unknown. Positive outcomes were the most common (35%), and also included novel and/or effective interventions aimed at perpetrators such as physical treatment, social support, and communication. Few (1%) interventions had negative outcomes. Many interventions could not be implemented (21%), often due to a lack of funding or victim refusal. Results suggest changes to policy, practice, and research methodology, which could increase positive outcomes through facilitation of intervention implementation and improved data access.

Abstract
Extracorporeal membrane oxygenation (ECMO) can provide respiratory and cardiac support to patients in reversible devastated conditions. Heparin is the mainstay for anticoagulation during ECMO. Bivalirudin, a direct thrombin blocker, may represent an effective alternative for patients suffering from heparin-induced thrombocytopenia (HIT). We present the first case of a Chinese patient who experienced HIT and received bivalirudin anticoagulation during ECMO. In addition, we present a systematic review for this topic. We searched PubMed, EMBASE, and Cochrane Library (up to April 20, 2020) for studies that included patients undergoing ECMO, presenting with HIT, requiring bivalirudin treatment, and reporting relevant outcomes. The literature review yielded 15 studies involving 123 patients, amongst whom 58 patients were confirmed or suspected HIT patients, and 76 patients received bivalirudin as an anticoagulant for ECMO. Twelve studies were included for quantitative synthesis, and 46 patients were retrieved. The mean age of these patients was 46 years, and 30 patients were males. The average maintenance rate of bivalirudin was 0.27 ± 0.37 mg/kg/h, in order to maintain a target of activated clotting time (ACT) of 160–220 s. Additionally, bivalirudin doses in patients with continuous renal replacement therapies (CRRT) and patients without CRRT were 0.15 ± 0.06 mg/kg/h vs 0.28 ± 0.36 mg/kg/h, respectively (p=0.15). Most of the patients with confirmed HIT improved platelet counts in 3.3 ± 2.8 days after switching to bivalirudin anticoagulation. The patient-level data showed that 29 cases survived, 1 reported major bleeding, and 4 reported thrombotic events. Bivalirudin might be a promising optimal choice for ECMO anticoagulation in patients with HIT. A tailored protocol for management of bivalirudin treatment during ECMO should be developed with caution. Further prospective studies are necessary to standardise the use of bivalirudin.

Abstract
Background Airway-gastric fistulas (AGFs) are rare but life-threatening complications after esophagectomy for esophageal cancer. Their effective and reasonable management is challenging and still controversial. This study reports the classification and management strategies of post-esophagectomy AGF based on a retrospective analysis of 26 cases in two large volume centers in China. Methods Between January 2000 and December 2017, 6,316 consecutive patients with esophageal carcinoma underwent esophagectomy. AGF was verified in 26 patients. The patients with AGF were divided into two types based on the anatomic characteristics of the fistula. Type I was characterized by the presence of fistula orifices in digestive tract that were higher than those in the airway and were treated with conservative management. Type II had both fistula orifices located on the same horizontal plane and were treated with surgical management. Pearson Chi-Square (R software) was used to compare mortality rates. Results From January 2000 and December 2017, 26 cases occurred AGF in 6,316 consecutive patients with esophageal carcinoma underwent esophagectomy and the incidence of AGF was 0.4%. Ten of 12 patients with type I AGF survived. Nine of 14 patients with type II AGF died. There was a significantly difference in the mortality rates between patients with AGF type I and II, which was 16.7% (2/12) and 64.3% (9/14) (χ2=6.003, P=0.014), respectively. Conclusions AGF may be classified into two types according to the anatomic characteristics. Type I patients may be cured by conservative management and type II patients, require surgical intervention with pedicled tissues flap wrapping of the airway.

Abstract
The proposed methodology for optimizing energy efficiency, based on good management of the aeration process through the implementation of an appropriate control strategy, achieved reductions of more than 40% in energy consumption at the San Pedro del Pinatar Wastewater Treatment Plant (WWTP) (Murcia, Spain). Phases I and II of this methodology managed to reduce the oxygen needs of the microorganisms in the biological system, optimize the efficiency of oxygen transfer to the biological reactor and redesign the installation to correct abnormal energy loss situations. In addition, we established the basis for Phase III, which implemented a control strategy to achieve stable values close to the setpoints of the fundamental operating parameters of the aeration process. The control system is based on the measurements recorded by strategically installed sensors and mathematical algorithms based on models, achieving an expert adaptive-predictive system that regulates aeration both in the biological stage by activated sludge and the aeration of the installed ultrafiltration membrane system. The objectives were: (i) to achieve automatic execution of the best management strategy; (ii) to reduce the energy demand; (iii) to improve the operation and stability of the process; (iv) to reduce operating costs; and (v) to contribute to the fulfillment of the sustainable development objectives.

Abstract
Left polyorchidism was found in a 2-month-old boy with a left scrotal mass. As he was asymptomatic and all testes were in the scrotum, he was conservatively followed up. At 17 years of age, he presented with left acute scrotum due to testicular torsion of the left supernumerary testis. Counterclockwise 720-degree rotation of the left supernumerary testis was noted during emergency surgery, and orchidopexy of the 3 testes (2 left testes and 1 right testis) was performed. Biopsy of the left supernumerary testis demonstrated spermatogenesis and no malignancy. One and a half years after surgery, all testes were viable without atrophy.Polyorchidism is a rare condition and there is no consensus on the management of asymptomatic cases detected early in life. The position of the supernumerary testis (intrascrotal or extrascrotal) is important when deciding the management strategy because of the risk of malignancy. If conservative management is selected initially, elective surgery, such as prophylactic orchiectomy or orchidopexy, may be needed because of the risk of malignancy and torsion.

Abstract
Background: A sore throat is one of the common causes behind visits to the physician and antibiotic overtreatment in the world, especially in Iran. There are six ways of approaching pharyngitis patients. It is necessary to perform a cost-effectiveness analysis and find the best approach in all situations on group A streptococcus (GAS) pharyngitis management to propose a pharyngitis guideline. Method: The decision tree of managing pharyngitis and its complications was drawn. The probability of every status and the branches of the tree were derived from the literature, and the cost of related diseases and complications were calculated based on the dossiers of the patients in two main pediatric central hospitals in Tehran, Iran. Further, cost-effectiveness, sensitivity, and threshold analyses were conducted to find out the best management strategy. Moreover, for a situation analysis of pharyngitis management in Iran, a questionnaire was designed and given to general practitioners and pediatricians; 130 subjects responded to it. The results were then analyzed. Results: The rapid test antigen (RTA) and culture strategy were proved to have the highest effect on the quality-adjusted life year. In addition, a less expensive strategy was solely observed to be the RTA. The worst effect gained (most quality-adjusted lost days) was, however, from the “treat none” strategy. Conclusion: According to our cost-effectiveness analysis, the best management of pharyngitis occurs in RTA alone, followed slightly by culture strategies; the “RTA then culture if needed” and “RTA and culture” approaches become possible options after them. The “treat all” and “treat none” approaches, however, were not proper strategies in any case.

Abstract
AIM To evaluate the effectiveness of a mobile application-assisted nurse-led management model in childhood asthma. BACKGROUND Studies have shown that a nurse-led asthma management model can improve asthma outcomes. However, the role of a mobile application-assisted nurse-led model in paediatric asthma management has not been studied well. DESIGN A multi-centre randomized clinical trial. METHODS The trial was conducted between March 2017-March 2018. A total of 152 children (6 to 11.9 years old) were enrolled, with 77 children in the experimental group and 75 in the control group. All children received nurse-led asthma management and other routine treatment measures, including inhaled corticosteroids. Meanwhile, a mobile application was used to manage asthma only for children in the experimental group. Primary outcome was frequency of asthma exacerbations. All outcomes were evaluated twice a month for 12 months. RESULTS Compared with the pre-enrollment period, frequency of asthma exacerbations decreased in the post-enrollment period in the two groups, with a greater decrease in the experimental group. Compared with children in the control group, children in the experimental group had better secondary outcomes, such as improved adherence, higher Childhood Asthma Control Test scores, decreased respiratory tract infections, days of antibiotic use, days of school absence, parental work loss, and medical expenses. CONCLUSION A mobile application-assisted nurse-led management model decreased asthma exacerbations and improved secondary outcomes in children with asthma. Further research is needed to verify its validity in larger population samples. IMPACT Children with asthma benefited from a nurse-led asthma management model when combined with mobile application. This trial suggested that computer and Internet technologies should be incorporated into nurse-led asthma strategy in paediatric asthma management. TRIAL REGISTRATION The current trial was registered online with the Chinese Clinical Trial Registry (registration number: ChiCTR1800016726).

Abstract
With more long-acting injectable (LAI) antipsychotics available for treating schizophrenia, each with variable durations of action (2 weeks to 3 months), it is important to have clear management strategies for patients developing breakthrough psychotic symptoms or experiencing symptomatic worsening on LAIs. However, no treatment guidelines or clinical practice pathways exist; health-care providers must rely on their own clinical judgment to manage these patients. This article provides practical recommendations-based on a framework of clinical, pharmacokinetic, and dosing considerations-to guide clinicians' decisions regarding management of breakthrough psychotic symptoms. Management options include ruling out/addressing medical illness or substance abuse/misuse as a contributing factor, addressing stressors, optimizing nonpharmacologic treatments, treating medical/psychiatric comorbidities, ensuring proper LAI administration technique, addressing missed LAI doses or lack of steady-state attainment, and increasing LAI dose directly or indirectly by shortening the injection interval (off-label). If these strategies do not work sufficiently with frequent monitoring, the LAI could be supplemented with a low dose of the corresponding oral formulation for fast symptom control (off-label). However, caution should be exercised with this strategy, because data on the safety of concomitant use of LAI and oral antipsychotics (OAPs) are limited, especially over extended periods. If symptoms abate, therapy optimization could be continued and slow discontinuation of the OAP could be considered. For persistent/worsening symptoms, the OAP should be increased to optimum effective dose while intensifying the initial steps used before it was added. If this fails, switching the OAP or LAI could be considered. We believe that these strategies will help clinicians manage breakthrough psychotic symptoms during LAI treatment and improve overall outcomes among those who can benefit from LAIs.

Abstract
TRIAL DESIGN The aim of this study was to identify independent risk factors for post-pancreatoduodenectomy (post-PD) abdominal fluid collections (AFCs) and evaluate our management protocol on it. METHODS A retrospective analysis of consecutive 2064 cases who underwent PD over the past decade in 1 single center was conducted. The patients were divided into AFCs and non-AFCs group. Univariable and multivariate logistic regression analysis was performed to identify independent risk factors of AFCs. The AFCs group was compared with the non-AFCs group with respect to the incidence of postoperative outcomes. The characteristics of AFCs were further analyzed in terms of clinical manifestations. RESULTS Two thousand sixty-four cases with pancreaticoduodenectomy were recruited and 15% of them were found AFCs. Diameter of main pancreatic duct ≤3 mm was found to be an independent predictor of AFCs (P < .001), along with soft pancreatic texture (P = .002), mesenterico-portal vein resection (P < .001), and estimated intraoperative blood loss >800 mL (P < .001). The incidence of mild complications was significantly higher in AFCs group than in non-AFCs group (34% vs 20%, P < .001), whereas no significant differences were noted in the rate of severe complications between these 2 groups (15% vs 15%, P = .939). CONCLUSION Enhanced drainage is recommended as an effective measure to decrease the incidence of severe complications caused by post-PD AFCs.

Abstract
A solitary pulmonary nodule is a round opacity less than 30 mm in diameter surrounded by normally aerated lung tissue. Determination of the character of the lesion following its detection (particularly when the identification was incidental) may require a complex diagnostic process. In most cases, nodules are benign in character; however, the probability of malignancy increases significantly for part-solid lesions. The main features that describe the solitary pulmonary nodule in computed tomography scans include their size, shape, density, presence of calcification and rate of growth. PET-CT examination provides additional information on the metabolic activity of the lesions, and MRI is helpful in assessment of local invasion of surrounding structures. Due to limited availability and highly specialized character, these examinations are not routinely used. Therefore, despite development of other imaging modalities, computed tomography remains the most important and crucial diagnostic tool. Clinical risk factors such as age or smoking status are very important for evaluation of the likelihood of malignancy of a nodular lesion. Due to the multidisciplinary nature of data required for complex assessment of a solitary nodular lesion, management routines are needed in the diagnostic process such as those proposed by the Fleischner Society.

Abstract
Chronic obstructive pulmonary disease (COPD) is characterized by long-term airflow limitation. Early-onset COPD in non-smoker subjects is ≥60 years and in the elderly is often associated with different comorbidities. Cognitive impairment is one of the most common feature in patients with COPD, and is associated with COPD severity and comorbidities. Cognitive impairment in COPD enhances the assistance requirement in different aspects of daily living, treatment adherence, and effectual self-management.This review describes various bioactive compounds of natural marine sources that modulate different targets shared by both COPD and cognitive impairment and hypothesizes a possible link between these two syndromes.

Abstract
RATIONALE Familial gigantiform cementoma (FGC) is a rare benign autosomal dominant fibrocemento-osseous lesion generally limited to the facial bones, typically in the anterior portion of the mandible; it is often associated with abnormalities of the long bones and prepubertal pathologic fractures. Owing to the small number of such patients, a uniform treatment criterion has not been established. This paper presents a patient with FGC who was treated in our department, and offers a systematic review of the patients reported in the literature. Our aim was to explore the treatment strategy for patients with FGC. PATIENT CONCERNS Our patient, a 13-year-old boy, presented with a painless enlargement of the mandible first noted 2 years earlier. It had grown rapidly over the preceding 8 months, affecting both his appearance and ability to chew. DIAGNOSIS Based on the pathologic, clinical, and radiographic features, FGC was diagnosed. INTERVENTIONS Mandibuloectomy was performed. The mandibular defect was immediately reconstructed with his right vascularized iliac crest flap. At the same time, a PubMed search was conducted to identify studies reporting on other patients with FGC. OUTCOMES A 3-dimensional computed tomography (3D-CT) scan demonstrated appropriate height of the new alveolar bone. Follow-up results showed recovery of the patient's appearance and mandibular function. He was free of recurrence at 4-year follow-up. LESSONS FGC is a rare benign fibrocemento-osseous lesion of the jaws that can cause severe facial deformity. Incomplete removal leads to more rapid growth of the residual lesion. Therefore, extensive resection is a suitable strategy to avoid recurrence. Defects of the facial bones found intraoperatively should be repaired with resort to an appropriate donor site. However, it is important to be aware that patients with FGC always have concomitant abnormalities of skeletal metabolism and structure, as well as a vulnerability to fractures of the long bones of the lower extremity. Therefore, the optimal management strategy should include a review of treatment options for other patients as reported in the literature. An optimal protocol can not only provide sufficient high-quality bone suitable for the reconstruction of bone defects, but also minimize complications and maximize quality of life.

Abstract
Hepatic encephalopathy (HE) is a reversible syndrome of impaired brain function occurring in patients with advanced liver diseases. The precise pathophysiology of HE is still under discussion; the leading hypothesis focus on the role of neurotoxins, impaired neurotransmission due to metabolic changes in liver failure, changes in brain energy metabolism, systemic inflammatory response and alterations of the blood brain barrier. HE produces a wide spectrum of nonspecific neurological and psychiatric manifestations. Minimal HE is diagnosed by abnormal psychometric tests. Clinically overt HE includes personality changes, alterations in consciousness progressive disorientation in time and space, somnolence, stupor and, finally, coma. Except for clinical studies, no specific tests are required for diagnosis. HE is classified according to the underlying disease, the severity of manifestations, its time course and the existence of precipitating factors. Treatment of overt HE includes supportive therapies, treatment of precipitating factors, lactulose and/or rifaximin. Routine treatment for minimal HE is only recommended for selected patients.

Abstract
Metabolic disorder has been frequently observed in chronic obstructive pulmonary disease (COPD) patients. However, the exact correlation between obesity, which is a complex metabolic disorder, and COPD remains controversial. The current study summarizes a variety of drugs from marine sources that have anti-obesity effects and proposed potential mechanisms by which lung function can be modulated with the anti-obesity activity. Considering the similar mechanism, such as inflammation, shared between obesity and COPD, the study suggests that marine derivatives that act on the adipose tissues to reduce inflammation may provide beneficial therapeutic effects in COPD subjects with high body mass index (BMI).

Abstract
Among chronic neurodegenerative disorders, Parkinson's disease (PD) is one of the most difficult and challenging to tackle as several motor and nonmotor features influence the patients' quality of life (QoL) and daily activities. Assessing patients QoL with valid instruments and gathering knowledge about the determinants that affect QoL in individuals with PD are the basis of an efficient caring strategy. In addition to the known motor symptoms, nonmotor disorders must also be comprehensively tracked and targeted for treatment to enhance QoL. A holistic strategy to maintain QoL in people with PD should consist of a multidisciplinary, personalized and patient-centered approach with timely administration of palliative care and efficient involvement of caregivers and family members.

Abstract
Ecological invasions are a major issue worldwide, where successful invasion depends on traits that facilitate dispersion, establishment, and population growth. The nonnative succulent plant Kalanchoe pinnata, reported as invasive in some countries, is widespread in remnants of seasonally dry tropical forest on a volcanic outcrop with high conservation value in east‐central Mexico where we assessed its mating system and demographic growth and identified management strategies. To understand its local mating system, we conducted hand‐pollination treatments, germination, and survival experiments. Based on the experimental data, we constructed a life‐stage population matrix, identified the key traits for population growth, weighted the contributions of vegetative and sexual reproduction, and evaluated management scenarios. Hand‐pollination treatments had slight effects on fruit and seed setting, as well as on germination. With natural pollination treatment, the successful germination of seeds from only 2/39 fruit suggests occasional effective natural cross‐pollination. The ratios of the metrics for self‐ and cross‐pollinated flowers suggest that K. pinnata is partially self‐compatible. Most of the pollinated flowers developed into fruit, but the seed germination and seedling survival rates were low. Thus, vegetative propagation and juvenile survival are the main drivers of population growth. Simulations of a virtual K. pinnata population suggest that an intense and sustained weeding campaign will reduce the population within at least 10 years. Synthesis and applications. The study population is partially self‐compatible, but sexual reproduction by K. pinnata is limited at the study site, and population growth is supported by vegetative propagation and juvenile survival. Demographic modeling provides key insights and realistic forecasts on invasion process and therefore is useful to design management strategies.

Abstract
A rare complication of acute or chronic pancreatitis is the formation of a mediastinal pancreatic pseudocyst (MPP), which is caused by tracking of pancreatic fluids through anatomical openings of the diaphragm into the mediastinum. Herein, we report the imaging characteristics of three cases of this condition. Our results revealed three features in common: (i) the connection between the mediastinum and the pancreatic cystic lesion; (ii) the presence of pleural effusions; and (iii) imaging findings consistent with chronic pancreatitis, such as pancreatic atrophy and calcifications and dilatation and/or stricture of main pancreatic duct (MPD). Serial diameter changes of the MPD and of the adjacent pseudocysts were necessary for the determination of the therapeutic strategy used in each case.

Abstract
OBJECTIVE This study examined the moderation effects of management strategies on the association between hindering self-focused attention and counseling self-efficacy. METHOD Participants were 160 counselor trainees. A hierarchical regression was used to analyze the data, and a simple effect analysis was used to explore the nature of the interaction. RESULTS Results indicated that, for trainees who used more basic counseling techniques, counseling self-efficacy remained the same no matter their hindering self-focused attention experiences. However, for those who used less basic counseling techniques, their counseling self-efficacy dropped when they had more experiences of hindering self-focused attention. Similarly, for trainees who used more self-awareness to understand clients, these trainees reported a similar level of counseling self-efficacy no matter their hindering self-focused attention experiences. Conversely, for those who used less self-awareness as a tool to understand their clients during their sessions, their counseling self-efficacy decreased when they had more experiences of hindering self-focused attention. CONCLUSION This is the first study that extends the literature on direct, linear relationships between hindering self-focused attention and counseling self-efficacy. Results suggested two strategies (i.e., use of basic counseling techniques and use of self-awareness to understand clients) significantly moderate the above association.

Abstract
Containment can be a viable strategy for managing invasive plants, but it is not always cheaper than eradication. In many cases, converting a failed eradication programme to a containment programme is not economically justified. Despite this, many contemporary invasive plant management strategies invoke containment as a fallback for failed eradication, often without detailing how containment would be implemented.We demonstrate a generalized analysis of the costs of eradication and containment, applicable to any plant invasion for which infestation size, dispersal distance, seed bank lifetime and the economic discount rate are specified. We estimate the costs of adapting eradication and containment in response to six types of breach and calculate under what conditions containment may provide a valid fallback to a breached eradication programme.We provide simple, general formulae and plots that can be applied to any invasion and show that containment will be cheaper than eradication only when the size of the occupied zone exceeds a multiple of the dispersal distance determined by seed bank longevity and the discount rate. Containment becomes proportionally cheaper than eradication for invaders with smaller dispersal distances, longer lived seed banks, or for larger discount rates.Both containment and eradication programmes are at risk of breach. Containment is less exposed to risk from reproduction in the 'occupied zone' and three types of breach that lead to a larger 'occupied zone', but more exposed to one type of breach that leads to a larger 'buffer zone'.For a well-specified eradication programme, only the three types of breach leading to reproduction in or just outside the buffer zone can justify falling back to containment, and only if the expected costs of eradication and containment were comparable before the breach.Synthesis and applications. Weed management plans must apply a consistent definition of containment and provide sufficient implementation detail to assess its feasibility. If the infestation extent, dispersal capacity, seed bank longevity and economic discount rate are specified, the general results presented here can be used to assess whether containment can outperform eradication, and under what conditions it would provide a valid fallback to a breached eradication programme.

Abstract
Some amino acids are more energetically costly to synthesize de novo, therefore many microbes have evolved to regulate the metabolic expenditure of the cell and reduce the energy burden of extracellular unrecyclable proteins. Several oral bacterial species take up amino acids and peptides obtained from proteolysis of host proteins and hence do not rely only on de novo synthesis. The aim of this study was to investigate if five oral bacterial species implement cost management strategies to reduce the energy burden of extracellular unrecyclable proteins. Since the relative de novo amino acid synthesis costs are proportional to the masses of the amino acids, the energy costs of producing proteins were assessed by calculating the mean amino acid mass for each protein. For Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, Prevotella intermedia and Streptococcus sanguinis, the outer membrane/extracellular proteins are made up of a much larger percentage of lower average mass amino acids whereas cytoplasmic proteins are made up of a larger proportion of higher average mass amino acid residues. These results are consistent with the five oral bacterial species employing energy-saving mechanisms in the production of extracellular unrecyclable proteins. Interestingly, the P. gingivalis and S. sanguinis genomes exhibited significantly lower predicted mean amino acid masses compared with those of the genomes of the other three species, suggesting that this may provide them with an energy advantage with respect to protein biosynthetic cost.

Abstract
Solitary pulmonary nodules (SPNs) are increasingly detected with the widespread use of chest computed tomography (CT) scans. The management of patients with SPN should begin with estimating the probability of cancer from the patient's clinical risk factors and CT characteristics. The decision-making process need to incorporate the probability of cancer, the potential benefits and harms of surgery, the accuracy of the available diagnostic tests and patient preferences. For patients with a very low probability of cancer, careful observation with serial CT is warranted. For patients in the intermediate range of probabilities, either CT-guided fine-needle aspiration biopsy (FNAB) or positron emission tomography (PET), is recommended. For those with a high probability of cancer, surgical diagnosis is warranted.

Abstract
AIM To optimise medication administration, prevent medication errors and improve inpatient safety. BACKGROUND Interventions are needed to reduce medication-related errors and to improve patient safety. METHOD A five-point management intervention strategy was developed and implemented. A quasi-experimental design was used to examine its effects. RESULTS Comparing pre-intervention data with post-intervention data, the rate of accurate compliance with medication policies and procedures increased from 86.7% (645/744 doses observed) to 97.5% (725/744). The success rate of medication administration procedures increased from 94.0% (466/496 doses observed) to 96.8% (480/496). Nurse-initiated medication error reports/total medication error reports increased from 77.1% (101/131) to 95.1% (58/61). Rate of inpatient satisfaction with medication increased from 92.1% (3427/3720) to 98.3% (3656/3720). Complaints related to nursing medication administration decreased from 23 to 6 (73.9% reduction). CONCLUSION The five-point management intervention strategy improved inpatient medication safety: medication errors were reduced, nurses' awareness and skills of medication safety enhanced, inpatient satisfaction improved. However, randomised controlled trials are needed to test its effectiveness. IMPLICATIONS FOR NURSING MANAGEMENT A systematic approach is vital to address the issues of medication errors and patient safety.

Abstract
Depressive disorders are a leading cause of disability worldwide and greatly impact morbidity, health care utilization, and medical costs. Major depression that does not resolve with adequate antidepressant treatment is termed treatment-resistant depression (TRD), There is no universally accepted definition of TRD and several criteria have been suggested to define it. Multiple factors can contribute to treatment resistance, including unrecognized comorbid medical or psychiatric illness, the use of concomitant medications, noncompliance, and psychosocial stressors. TRD is associated with extensive use of depression-related and general medical services, and poses a substantial economic burden. Current approaches to its management include the use of antidepressant strategies, such as increasing the dose of the antidepressant, augmentation strategies, combination strategies, and switching strategies, electroconvulsive therapy, and cognitive behavioral therapy. Although no definite algorithm exists for treating TRD, research in this area has advanced considerably in recent years. One approach to this is a clinical trial called STAR*D (Sequenced Treatment Alternatives to Relieve Depression). This has the potential to increase our understanding about the diagnostic and therapeutic aspects of TRD, to substantially reduce disability, and to enhance the quality of life in individuals with this condition.

Abstract
The study reports the results of a follow-up evaluation, conducted in 1994, of the impact of a training program for female unskilled metal workers that was implemented at the end of the 1970s. The program was designed to promote occupational skills development, and was first evaluated in 1979. On both occasions of evaluation the investment in training was examined from two perspectives, those of the training participants and management. Data were collected through semistructured personal interviews with key members of personnel management and through a group conversation session with a majority of the original course attendees. Supplementary background information was obtained from documents and records maintained by the organization. At some points, there was a convergence of views on the significance of the training program for occupational skills development, at others a divergence. These convergences and divergences are finally discussed and the findings of the study are related to other research on this particular kind of intervention.
