Authors: Kafar Marcin , Osvath Csaba , Scheffels Erin , Spinazola Lisa P. , Tillmann Lisa M.
Published: January 2020

On January 25th, 2019, The University of South Florida sponsored an event to honor the legacy of Carolyn Ellis and Arthur Bochner as they retire after more than 85 years (combined) teaching. In this paper, research collaborators, students, and friends present their testimonials commemorating their shared lives with Professors Ellis and Bochner. A collection of short stories reveals “official” and “non-official” (in some cases very personal) experiences as they were lived through, inviting readers to see how academic intergenerational relationships might develop as contextually situated and morally important.

Authors: Pujol Santiago , Rodriguez Mario E.
Published: January 2020

Se evalúa el desempeño observado de muros divisorios y de fachada durante el terremoto del 19 de septiembre de 2017 en la Ciudad de México. Se pretende interpretar las razones de los daños observados en este terremoto para definir posibles cambios en normativas de construcción tanto en México, como en Latinoamérica, que lleven a un comportamiento aceptable de edificaciones no sólo para el terremoto de diseño, sino también para terremotos de menor intensidad, como fue el ocurrido en la Ciudad de México el 19 de septiembre 2017. Se estiman de manera aproximada las distorsiones de entrepiso de una población de edificios empleando un registro de aceleraciones obtenido en este terremoto, y los resultados se comparan con distorsiones permisibles para la población de edificios y para dos casos de estudio seleccionados para esta investigación.

Published: January 2020

Neste trabalho é apresentada a avaliação do desempenho térmico de cobertura vegetada sobre guarita de fibra de vidro para primavera-verão de 2018 em Curitiba/PR. Compararam-se guaritas em condição experimental (ME) e controle (MC) para três configurações de cobertura (substrato; substrato e vegetação; substrato, vegetação e tela de sombreamento), com e sem sombreamento de janelas. A análise de conforto e estresse térmico seguiu parâmetros normativos de índice de bulbo úmido e temperatura de globo - IBUTG e temperatura efetiva - TE. A envoltória de fibra de vidro interferiu na temperatura do ar nos dois módulos, sendo a diferença na temperatura interna do MC e ME de apenas 2 °C. Entretanto, quanto às temperaturas de superfície sob a cobertura, o sistema de cobertura vegetada do ME ofereceu amortecimento e atraso térmico, atingindo uma diferença de até 12 K relativamente ao MC. Na comparação ME vs. MC, não se verificaram horas em estresse por calor no IBUTG, porém os valores de TE, em sua maioria, migraram para a condição de conforto, com a cobertura vegetada. Outra técnica explorada neste artigo é baseada na análise termográfica. Os resultados mostraram desempenho térmico superior do ME se comparado ao MC, confirmando as medições pontuais de temperatura de superfície.

Em um primeiro momento, trazendo brevemente referenciais teóricos que incorporam a literatura à historiografia, o texto advoga acerca do uso deste tipo de fonte, discutindo suas potencialidades e limitações; em seguida, faz considerações sobre a narrativa ficcional e apresenta dezesseis categorias de análise que podem ser utilizadas pelo pesquisador para interrogar a fonte literária no fazer da pesquisa historiográfica. Por fim, lançando mão de duas dessas categorias, apresentamos um exercício interpretativo a partir do livro “Planolândia”, de Edwin A. Abbott, cuja história tem, como personagens, entes geométricos. Tomada como fonte histórica, tal obra permite compreender ainda melhor várias tensões da sociedade vitoriana e, dentre essas, nosso estudo foca no modo como Abbott ressignifica os entes geométricos para representar a mulher da sociedade inglesa.
SISTEM PATRIARKI DAN KEKERASAN ATAS PEREMPUAN
Authors: Mutiah Riska
Published: January 2020

Tatanan patriarki merupakan sebuah sistem sosial yang menempatkan laki-laki sebagai sosok otoritas utama yang sentral dalam organisasi sosial. Tatanan patriarki inilah yang menyebabkan perempuan menjadi subordinasi, termarginalkan, bahkan memperoleh ketidakadilan di dalam masyarakat. Tatanan patriarki mengabsahkan superioritas laki-laki dan inferioritas perempuan yang tidak hanya kita temui pada satu atau dua kelompok masyarakat namun dapat kita temui di seluruh belahan dunia dengan kasus yang paling parah terdapat pada negara-negara dunia ketiga, dimana Indonesia adalah salah satunya. Sampai hari ini catatan Komisi Nasional Anti Kekerasan Terhadap Perempuan menyebutkan setiap 2 jam sekali terdapat 3 perempuan Indonesia yang mengalami kekerasan seksual dan 60% kasus kekerasan seksual terhadap perempuan terjadi di dalam ranah domestik korban. Bagi Luce Irigaray seksualitas dan hasrat laki-laki dalam bentuk alat kelamin adalah prinsip pengaturan tatanan simbolik dan melalui hal tersebut kuasa sosial dijalankan. Wacana-wacana universal, apakah itu filsafat, ilmu, atau kesusastraan semuanya diseksualisasikan dalam wacana maskulin. Jelas bagi Irigaray, nilai-nilai pencerahan (renaisans) tidak berlaku bagi perempuan. Karena hal tersebut, posisi sosial perempuan hari ini masih termaginalkan, tidak dianggap sebagai subjek melainkan sebagai objek seksual. Perempuan harus paham mengenai kondisi ini, agar tidak terus-menerus berada di dalam kekuasaan dominasi maskulin, setidak-tidaknya perempuan harus berusaha untuk keluar dari konstruk sosial yang telah dilekatkan tersebut. Yang perlu kita sadari bahwa membalikkan tatanan keseimbangan kekuasaan maskulin adalah mustahil jika tidak dilakukan secara bersama-sama oleh laki-laki dan perempuan, karena sistem patriarki telah menancapkan kukunya begitu dalam pada tatanan sosial kita.

Authors: Naamy Nazar
Published: January 2020

Religiousness is the knowledge level, belief, realization and full of comprehension of a person for the religion teachings which he believes, or an attitude of surrender to an existing strength outside of himself embodied in the activities and individual behavior in everyday life which include five dimensions: religious beliefs, worship, religion practice, religious knowledge, full of comprehension, and religious practice. The main problems in this research are: How is the understanding of Islam in the community of DasanCermen Village, Sandubaya Sub-district, Mataram City? How is practice of the teachings of Islam in the community of DasanCermen Village, Sandubaya Sub-District, Mataram City? What do factors influence people’s spirit in building DarulHidayah mosque in DasanCermen village, Sandubaya Sub-district, Mataram City? The purpose of this research is to analyze the religiousness level of Dasan Cermen community and solidarity to build a mosque by using the sociology theory of Emile Durkheim. The type of this research was field study (field research) and the method used was qualitative data analysis that is analytic descriptive. This research also used phenomenology approach which included: daily activities of society, talks directly or indirectly, forms of religious activity, and intensity of society in the utilization of mosques. From the study conducted, this research found that the factors which encourage the DasanCermen community to build a mosque is a factor of ideology of rewardfrom Allah, a good collective solidarity passed down through the rural society, written rules and on the demands of sodakoh of road users who are so enthusiastic for the establishment of Darul Hidayah mosque. In addition, the DasanCermen community already has a mechanical solidarity to ideology in building a mosque. Although DasanCermen community is urban society, solidarity in building mosque is seen from the ideology of their religious understanding. This ideology also evolved as their mechanical solidarity as a rule which has been passed down from its predecessors, because the people still have a solid communal life in which the citizens have same interests and same awareness.

City branding is an effort to build a particular image of a city. Semarang is one of Indonesia’s big cities that has not yet succeeded in finding the right brand to represent it. The researcher has conducted a pilot research study that aims to build Semarang’s city branding as The Cinematic City. It is due to Semarang’s background of often becoming a shoot location for famous movies. South Korea is well known because of its pop cultures, such as drama. Drama is one of the main factors that contribute to the increasing number of foreign visitors. They mostly visit popular drama shooting locations as their destinations. These kinds of tourism site are successful at developing emotional branding in the visitor’s minds. Looking at the similarity of South Korea and Semarang will help Semarang to learn a lot from what South Korea has done. This research aims to analyse how emotional branding represented through the Korean drama-based tourism site gimmicks. This research used the Emotional Branding theory by Marc Gobe. It assumed that emotional bonding is an essential thing in terms of engaging the customer and product in a particular phase. The main subjects of this research are the gimmicks in Nami Island. The result shows that the Relationship Aspect fulfilled by changing the theme and properties according to the season. For the Five Senses Experience, it only employs the sense of sight and touch by creating many gimmicks that can be a photo-taking hot spot. The Imagination aspect fulfilled by the unique design of the Emotional Identity put forward, such as the snowman.

Authors: Ruslianto Ruslianto
Published: January 2020

Mangrove forests take an essential role in mitigating climate change, through its ability of photosynthetic and storing carbon. Information on biomass and carbon potentially stored in mangrove forests is very important for presenting allometric models as a reference for estimating plants biomass. To date, there have been 15 allometric models for Rhizophora sp., but allometric models for estimating Rhizophora sp. biomass in Polewali Mandar regency remain unidentified. Rhizophora apiculata in Polewali Mandar District is widespread species, almost found in all mangrove forest areas.  The research was carried out through 4 stages, which were selection of 10 tree samples, measurement of fresh weight, measurement of moisture content, and measurement of dry weight (biomass). Substitution of measurement values in allometric equations, and analysis of data used the scoring method coefficient of determination variable (R2), bias, error-index, and Mean Square Error Prediction. The study found that the best allometric model with the highest scoring value was Ŷ = 1.02D0,949H1,142.
Responses of Individual Plant Species, Functional Groups, α- and β-Diversity to Short-Term Grazing Exclusion under Severe Drought Episode in Long-Term Grazed Alfa-Steppes

Published: January 2020

Grazing exclusion has been proved to be one of the main measures for rehabilitating degraded arid steppes. However, the effect of this management practice on plant species diversity and composition is ambiguous, specially under prolonged droughts. Concurrently considering the responses of individual plant species, diversity of functional groups, α-diversity, and β-diversity (and its components) may be crucial to the holistic understanding of grazing exclusion effects on plant communities under drought conditions. Here, we investigated the response of these diversity measures to short-term sheep exclusion under severe drought episode in arid steppes of Alfa-grass (Stipa tenacissima) with a long evolutionary history of livestock grazing. Individual species responses were tested based on species occurrence and abundance in either grazed or grazing-excluded steppes, in addition, we used indicator species analysis to assess the strength of the association between plant species and management type. Likewise, α-diversity, abundance- and incidence-based β-diversity, as well as the functional groups’ diversities were quantified using Hill Numbers and compared between the two management types. Sheep grazing exclusion enabled the recovery of various Alfa-steppe indicator species and improved the size of regional species pool, overall α-diversity, and the diversity of therophytes. This management practice decreased the abundance-based β-diversity and the nestedness-resultant fraction of the incidence-based β-diversity at the local scale, while at the landscape scale increased the abundance-based β-diversity and its balanced variation fraction and reduced the incidence-based β-diversity and its turnover component. Furthermore, protection from grazing altered β-diversities scaling patterns by maintaining higher balanced variation in species abundance at large spatial scale and greater abundance-gradient in species composition at the fine-scale. Our results suggest that the implementation of short-term grazing exclusion in degraded arid steppes would be the appropriate management practice for vegetation restoration and plant diversity conservation during prolonged drought periods.

Published: January 2020

Fast growing woody crops are currently a very important source for the generation of energy biomass. As short-rotation woody crops, the genus Paulownia has already attracted growing attention. These trees are used to produce biomass and reduce the carbon dioxide concentration in the atmosphere. Most projects for biomass production, however, may affect soil properties and status. For this reason, it is important to know the effects of Paulownia plantations on the microbiological properties of the soils on agricultural areas in Poland. This article provides information on plant parasitic nematodes inhabiting the root zone of Paulownia tomentosa L. in Poland. The only report of Meloidogyne hapla Chitwood, 1949 shows the potential pathogenicity of the root-knot nematodes. Furthermore, nothing is known about plant parasitic nematodes inhabiting the root zone of Paulownia tomentosa L.in Poland. Determining the trophic group of plant parasitic nematodes was undertaken by a process of centrifugation. Measurements showed a decrease in the population reproduction factor (Pf/Pi) which reached a value of 0.1. Paulownia tomentosa L. taken from seven different locations in Poland revealed the presence of M. hapla.

Teaching surgery – a review
Authors: Żyluk Andrzej
Published: January 2020

Introduction: Teaching medicine is a specific task consisting of transferring current medical knowledge and rules of medical practice to students. Teaching surgery traditionally includes acquiring manual skills. This article touches several issues concerning surgical education (curriculum) in the course of medical studies. Attention was paid to the specificity of operative room experience, risk of intimidation, anxiety provocation, and potential benefits. The factors which motivate surgeons to engage in teaching students were discussed.

Conclusions: It was noticed that the range and methods of transferring medical knowledge during medical studies (the curriculum) frequently does not comply with the requirements of future medical practice. The usefulness of frequent everyday testing of acquired knowledge was emphasised. Unreasonable hopes relevant to the introduction of novel techniques of teaching medicine in training centres with skills learning on dummies and simulators were questioned. The importance of ward-round sand simple manual skills teaching was emphasised.
Fatal intoxication with PMMA – a novel designer analogue of amphetamine
Authors: Potocka-Banaś Barbara , Janus Tomasz , Majdanik Sławomir , Borowiak Krzysztof
Published: January 2020

Introduction: New designer drugs of the amphetamine class like 4-methoxyamphetamine (PMA) and 4-methoxymethampheta-mine (PMMA) elicit psychoactive effects in the central nervous system (CNS) by enhancing monoaminergic neurotransmission. These substances are substrates for neurotransmitter transporter proteins, and after binding with them they penetrate inside the cells. PMA and PMMA also reverse the transport of endogenic neurotransmitters and stimulate their increased release into the synaptic gap. PMMA has a weaker psychostimulating effect and a stronger hallucinogenic effect than PMA.

Materials and methods: The article presents the case of fatal PMMA intoxication in a 28-year-old man. The post-mortem forensic toxicological analysis of collected blood samples was performed using the LC/MS/MS technique. The analysis detected 213 ng/mL of amphetamine, 270 ng/mL of 3,4-methylenedioxymethamphetamine (MDMA, Ecstasy), and 4585 ng/mL of PMMA.

Results: The cause of death was acute multiple organ failure resulting from heavy intoxication with psychoactive substances, particularly with PMMA.
Doctors experiences on the quality of care for pesticide poisoning patients in hospitals in Kampala, Uganda: a qualitative exploration using donabedian’s model

Published: January 2020

Background Pesticides are responsible for a significant percentage of deaths globally with majority occurring in sub-Saharan Africa. Deaths due to pesticide poisoning can be reduced if poisoning cases are managed optimally. However, the quality of care given to pesticide poisoning patients is still insufficient especially in sub-Saharan Africa. This study was aimed at exploring doctors’ experiences on quality of care for pesticide poisoning cases in hospitals in Kampala, Uganda.Methods Fifteen (15) in-depth interviews were conducted with doctors who were directly involved in management of pesticide poisoning patients in the accident and emergency, Medicine, Pediatrics and Intensive Care Unit wards in 5 hospitals in Kampala, Uganda. All interviews were transcribed and subjected to directed content analysis with the guidance of the Donabedian model of quality of care which emphasizes structure, process and outcome measures as pertinent ensuring quality care.Results Doctors reported structural, process and outcome facets that support diagnosis and treatment of pesticide poisoning cases improved the quality of care provided by doctors. Among the structures includes hospital units such as Intensive Care Unit (ICU), pediatrics and internal medicine; equipment and clinical guidelines such as airway, breathing and consciousness (ABC) protocol; and doctors’ knowledge and experiences. Doctors relied on history, and signs and symptoms to establish the cause and severity of pesticide poisoning. However, some patients and caretakers provided inaccurate pesticide poisoning history. Due to its availability in hospitals, doctors largely relied on atropine to manage pesticide poisoning cases whether or not relevant to treat the actual pesticide poisoning. Although majority of the cases treated recovered, those due to suicide were further referred to the hospital psychiatrist. Sharing experiences of managing pesticide poisoning patients among health workers and engaging in sensitization outreaches against pesticide poisoning were reported as potential activities to improve quality of care for pesticide poisoning patients.Conclusion Doctors reflected on the structure, process and outcome measures of quality of care given to pesticide poisoning patients. The implications of hospital structures and clinical process to the quality of the outcomes of care demonstrates their importance to improve management of pesticide poisoning cases in hospitals in Kampala, Uganda.
Combined use of apatinib mesylate and vinorelbine versus single use of vinorelbine in recurrent or metastatic triple-negative breast cancer: study protocol for a randomized controlled clinical trial
Authors: Wu Shuo , Zhang Liang , Li Huan , Xu Junnan , Jiang Cui , Sun Tao
Published: January 2020

Background: The emergence of new molecular targeted drugs provides new prospects for the treatment of advanced breast cancer; the future therapeutic trend includes chemotherapy combined with molecular targeted therapy. Apatinib mesylate, a novel, small anti-angiogenic agent, highly selectively inhibits the activity of vascular endothelial growth factor receptor-2 tyrosine kinase. Apatinib mesylate also blocks the signaling of vascular endothelial growth factor binding to its receptor, thereby, strongly inhibiting tumor angiogenesis and exerting an anti-tumor effect. However, a randomized controlled clinical trial of apatinib combined with vinorelbine for triple-negative breast cancer (TNBC) has not been reported. We will compare the therapeutic effect of vinorelbine alone or in combination with apatinib mesylate in patients with recurrent or metastatic TNBC in North China who have received at least two drug treatments including anthracyclines and taxanes. Methods/analysis: This study is a triple-blind, randomized, placebo-controlled, parallel-group clinical trial. We plan to include 164 female patients with locally recurrent or metastatic TNBC and without BRCA1 mutation (as BRCA -positive patients would have poor responses to the therapeutic methods designed in this study), admitted at the Liaoning Cancer Hospital & Institute, Northeast China. All enrolled patients will be randomized to orally take vinorelbine alone (40 mg orally, thrice a week (Mondays, Wednesdays, and Fridays) in each 3-week cycle) or combined with apatinib mesylate (500 mg orally, once daily of each 3-week cycle). Radiographic assessment will be performed every 6 weeks for 36 weeks, and every 9 weeks thereafter. The primary outcome is measurement of progression-free survival and secondary outcomes include overall survival, disease control rate, objective response rate, and incidence of adverse events at grades 3 and 4 as defined by the National Cancer Institute Common Toxicity Criteria [NCI-CTC] Version 4.0. Outcome measures will be evaluated at baseline (< 2 weeks before starting treatment), every 6 weeks during treatment, and at 4 weeks and every 3 months after treatment discontinuation. Discussion: Based on the data from this trial, we hope to identify a treatment plan that is suitable for female TNBC patients in Northeast China who have been treated with anthracyclines and taxanes. Trial registration: ClinicalTrials.gov (identifier: NCT03932526). Registered on April 30, 2019.
Caring Behavior And Associated Factors Among Nurses Working In Jimma University Specialized Hospital, Oromia, South West Ethiopia, 2019
Authors: Oluma Adugna , Abadiga Muktar
Published: January 2020

BACK GROUND: Caring behaviors are actions concerned with the wellbeing of the patients such as sensitivity, comforting, attentive listening, honest and nonjudgmental acceptance. Nurses have an opportunity to convey caring and feeling being cared through their behavior. Behavior associated with caring has a paramount role in linking nursing interaction to the client in experiences but, the concept is ambiguous and elusive toward different scholars to reach on common understanding which is a myth in dealing with caring behavior. Only a few studies have been done on the caring behavior and associated factors globally, and there is a limitation of study done in Ethiopia particularly in this study area. Therefore; the purpose of this study was to assess caring behavior and its associated factors among nurses working in Jimma University specialized hospital, southwest Ethiopia. METHODS: The institutional-based cross-sectional study design was conducted on a sample of 224 nurses working in Jimma university specialized hospital from March 20-April 20, 2019 . Data were collected by self-administered questionnaire. Descriptive statistics including frequency table, mean, standard deviation and percentage were employed. Bivariate and multiple linear regression analysis was used with regression coefficient (β), coefficient of the determinant (R²), CI 95% and p<0.05 were used for statistical significance. RESULTS: The overall proportion of nurses caring behavior was 80.3% which was mostly measured in terms of professional –technical (82.9%) and psychosocial (81.3%) dimension. Job satisfaction as personal satisfaction (beta=1.12, p=0.00), professional satisfaction, (beta=1.07, p=0.00), joint participation in caring process (beta=0.58, p=0.00,) satisfaction with nurse management (beta=0.85, p=00) were significantly associated with caring behavior. CONCLUSION: The proportion of nurses who had a high perception of caring behavior was found to be lower. Thus, all predictors have their own effect on enhancing job satisfaction, improving and creating conducive management and working environment to increase caring behavior.

Backgroud
Pancreatic cancer is a highly malignant tumor of the digestive system. This secretome of pancreatic cancer is key to its progression and metastasis. But different methods of protein extraction affect the final results. In other words, the real secretion of proteins in cancer cells has been changed. Based on mass spectrometry, we analyze the secretome from the serum-containing and serum-free medium, using different protein pretreatment methods. This study aims to identify dissociation factors in pancreatic cancer.
Methods
In this study, pancreatic cancer cells were cultured in serum-containing or serum-free medium, and the corresponding supernatants were extracted as samples. Subsequently, the above samples were separated by size exclusion chromatography (SEC), and peptide segments were identified by LC-MS/MS. The final results were identified via the hamster secreted protein database and a public database.
Results
Although the number of identified proteins in the serum-free medium group was high, the real secretion of proteins in pancreatic cancer cells was changed. There were six significant secreted proteins in the serum-containing medium group. Survival analysis via the TCGA database suggested that patients with higher expression levels of YWHAG showed a worse overall survival rate than those with lower YWHAG expression.
Conclusions
Our study demonstrated the results in the serum-containing medium group were more similar to the real secretome of pancreatic cancer cells. YWHAG could be used as a prognostic indicator for pancreatic cancer.

Background: Dementia is a serious and growing health problem, and since most people with dementia live at home, caring responsibilities generally fall to family members. Caregivers are often inadequately supported by formal health services and have poorer psychological and physical health. Our study aimed to compare the contributions of publications from different countries, institutions and authors and present a bibliometric analysis to determine the hotspots and trends in research on the health of and interventions for family dementia caregivers. Methods : Studies published during 1988-2018 were extracted from the Science Citation Index Expanded of the Web of Science. Each abstract of publications was evaluated to obtain the basic information. A bibliometric analysis was used to evaluate the number or cooperation networks of publications, countries, institutions, journals, citations, authors, references, and keywords. The resulting articles were analyzed descriptively, and the publication keywords were visualized using VOSviewer. Results: Five hundred forty-two articles were identified.The annual number of relevant publications has steadily increased since approximately 2006. The USA has the highest number of publications (36.2%), followed by the UK (12.9%). China entered the field late, but research conducted in China has rapidly developed. The most productive institution, journal, and author in this field are University College London, the Journal of the American Geriatrics Society, and Orrell M from the UK, respectively. A co-occurrence analysis of the keywords reveals a mainstream research focus on burden, depression, quality of life, and corresponding interventions for people with dementia caregivers. The keywords “psychosocial intervention”, “long-term”, “e-learning/online”, “communication”, and “qualitative research” reflect the latest hotspots, appearing in approximately 2017-2018. Conclusion: Our study details the performance statistics, main topics and trends research on the health of and interventions for dementia caregivers from 1988 to 2018 and provides a comprehensive analysis. Keywords: family dementia caregivers, health and intervention, global research trends, bibliometric analysis

Background: As an inodilator, milrinone is commonly used for patients underwent coronary artery bypass graft surgery (CABG) because of its effectiveness in decreasing cardiac index and mitral regurgitation. This study was to perform a systematic meta-analysis of existing studies in the past 20 years to evaluate the impact of milrinone on mortality in patients underwent CABG surgery.

Methods: We performed a systematic literature search on the application of milrinone in patients underwent CABG surgery, which published between 1997 and 2017 in BioMed Central, PubMed, EMBASE, and the Cochrane Central Register. The included literatures should be set as milrinone compared to a group receiving either placebo or standard treatment, and further compare to systemic administration.

Results: The network meta-analysis included 723 patients from 16 randomized clinical trials. Overall, there was no significant difference in mortality between the milrinone group and the placebo/standard care group when patients underwent CABG surgery. Besides that, 9 trials (with 440 randomized patients), 4 trials (with 212 randomized patients), and 10 trials (with 470 randomized patients) reported that the occurrence of myocardial infarction (MI), myocardial ischemia, and arrhythmias in the milrinone group were decreased comparing with the placebo/standard care group, respectively. Between the milrinone treatment and placebo/standard care groups, the occurrence of myocardial infarction, myocardial ischemia, arrhythmias was all significantly different. However, the occurrence of stroke and renal failure, duration of inotropic support (h), need for intra-aortic balloon pump (IABP), and mechanical ventilation (h) between these two groups showed no differences.

Conclusions: Based on the current results, milrinone might be unable to decrease the mortality in adult CABG surgical patients, but can significantly ameliorate the occurrence of MI, myocardial ischemia, and arrhythmias compared with placebo-treated patients. These results provide evidence for further clinical application of milrinone and therapy strategies for CABG surgery. However, along with milrinone application in clinical use, sufficient randomized clinical trials need to be collected, and the potential benefit and adverse effects should be analyzed and reevaluated.

Published: January 2020

Background New doctors are expected to assess and manage acutely deteriorating patients from their first days in the hospital. However, current evidence suggests that medical graduates are not prepared for this. We aimed to explore junior doctors’ first experiences with unwell patients and how they developed preparedness over time. Methods We conducted seven semi-structured interviews with doctors in their first postgraduate year. The interview transcripts underwent inductive thematic analysis using consensual qualitative research approaches. Themes identified were categorised into early experiences of unpreparedness, first experiences of genuine preparedness, and making sense of how they became prepared. Reflection on how participants progressed between the two was facilitated through a sorting and ranking exercise. Results Most participants initially felt unprepared when responding to acutely unwell patients. They described feeling overwhelmed, apprehensive and challenged. Two main challenges involved knowing when to escalate, and feeling expected to perform beyond their level of competency. A lack of acute care exposure at medical school was a common thread. All participants felt prepared to respond to unwell patients three to six months after starting work. Hands-on experience, reflection, simulation and multidisciplinary team-working were consistently ranked as the most useful learning experiences. Conclusion Starting work as a doctor is a challenging time and preparedness to manage an acutely deteriorating patient is a common area of concern. As preparedness in acute care ranks poorly compared to other outcomes, we see this as an important area for improvement. Our findings suggest that undergraduates may lack sufficient opportunities for scaffolded decision making in acute care, and that increasing the intensity of clinical shadowing may improve preparedness and should inform future educational interventions.

Background: Infectious diarrhea can lead to considerable disease burden around the world. Thus, the accurate prediction of infectious diarrhea epidemic is crucial for public health authorities. This study aimed to develop an optimal random forest (RF) model considering meteorological factors to predict morbidity of infectious diarrhea in Jiangsu Province, China. Methods: A RF model was constructed and compared with the classical autoregressive integrated moving average (ARIMA)/X models. Morbidity and meteorological data from 2012−2016 were used for model construction and the rest data in 2017 were used for testing. Results: The RF model considered atmosphere pressure, precipitation, relative humidity and their lagged terms, 1-4 weeks’ lag morbidity and the time variable as predictors. Meanwhile, a univariate model ARIMA(1,0,1)(1,0,0) 52 (AIC=−575.92, BIC=−558.14) and a multivariable model ARIMAX(1,0,1)(1,0,0) 52 with 0-1 week’s lag precipitation (AIC=−578.58, BIC=−578.13) were developed as benchmark models . The RF model outperformed the ARIMA/X models with a mean absolute percentage error (MAPE) of approximately 20% . The performance of the ARIMAX model was similar to that of the ARIMA model with MAPE approximately as high as 30%. Conclusions: The RF model well fitted the dynamic of the infectious diarrhea epidemic and achieved ideal prediction accuracy. It comprehensively combined meteorological factors and their hysteresis effects. It also integrated the autocorrelation and seasonality of morbidity. The RF model could be used to predict the epidemic level, and has good potential of practical application.
