La falsa democracia del espacio público Geopolítica, producción discursiva y cartografías del poder en América Latina
Authors: Felipe Narciso Carla Alexandra
Published: October 2020

En los últimos veinte años, el concepto de espacio público se ha vuelto dominante tanto en los discursos gubernamentales como académicos, sobre todo en regímenes políticos progresistas y democráticos de América Latina, y eso por el arbitrio ideológico y abstracto de lo público, del orden democrático y de la opinión pública moderna, lo cual ha sido determinante como marco legitimador de prácticas geopolíticas y discursos hegemónicos que determinan un statu quo que ha permitido al sistema capitalista neoliberal seguir reproduciéndose a partir de las estructuras urbanas y el desarrollo urbanístico en contextos de dominación y dependencia. En este sentido, el presente trabajo procura (des)mistificar la conformación hegemónica occidental del concepto de espacio público (como ámbito de la filosofía2 y esfera pública de deliberación política), desde la teoría crítica urbana y la teoría política feminista y cómo el mismo ha encontrado un territorio fértil de materialización discursiva y anclaje espacial de control y dominación de los países hegemónicos hacia Latinoamérica, reproduciendo un statu quo de colonización y explotación asociada a formas progresivas de politización teórica, a través de una trasnacionalización de la política, que se hace visible en los grandes proyectos de renovación urbana. Este trabajo se apoya de reflexiones teóricas, como marco analítico que permití hacer visible que el uso del concepto de espacio público no es neutral, pero está subsumido a una lógica política de legitimidad social y empoderamiento del capital hegemónico, y que ha tenido consecuencias espaciales, como una mayor segregación y fragmentación socioespacial, bajo un discurso democrático de “para todos”, inclusivo y del bien común que ha perpetuado en la reestructuración de nuevas formas de control y dominación.

No presente trabalho tem-se por objetivo evidenciar a importância da gestão escolar para a formação continuada de professores a respeito do tema Transtorno do Déficit de Atenção e Hiperatividade (TDAH). Apresenta-se como questão central de pesquisa: como as iniciativas de formação continuada, conduzidos pela gestão escolar, contribuíram para o processo de ensino-aprendizagem dos estudantes com TDAH? A pesquisa, de abordagem qualitativa e descritivo-bibliográfica, contou com a análise documental das atividades propostas no projeto de intervenção Formação Continuada sobre TDAH. Os autores basilares desta pesquisa são: Campbell (2009), Libâneo (2004), Lima (2002), Mazzota (1987), Mendonça e Silva (2015); além desses autores, a pesquisa utilizou documentos oficiais. Os resultados mostraram que há escassez de material sobre práticas pedagógicas com estudantes com TDAH, pois a maioria das pesquisas sobre a temática tem viés clínico; também foi evidenciado, por meio deste estudo, que os processos de formação continuada de professores podem trazer contribuições significativas para o desenvolvimento de conhecimentos por parte da comunidade escolar acerca das formas apropriadas de trabalhar com os estudantes com TDAH; que a formação continuada, principalmente sobre a educação inclusiva, é necessária para o aprimoramento de toda a equipe escolar, pois os membros internos e externos de uma comunidade necessitam do conhecimento científico quando se deparam com o ‘desconhecido’; e que cabe à equipe pedagógica e à gestão buscar os conhecimentos necessários para trabalhar com as especificidades dos estudantes com TDAH.

Published: October 2020

Background: A growing body of evidence suggest that the children’s physical activity (PA) level in early childhood education and care (ECEC) settings are insufficient. Since most children attend ECEC settings for many hours on most days of the week, and these institutions reach children across the socioeconomic spectrum, the ECEC settings may serve as an ideal avenue for increasing physical activity level, reduce sedentary time and enhance the overall health of young children. This paper investigates the effectiveness of the “Active Kindergarten – Active Children” study to increase children’s PA level and reduce sedentary time within the ECEC setting. Methods: Accelerometers were used to asses PA and sedentary time. A total of 116 three to four-year olds took part in a randomised controlled trial in 11 ECEC settings. Participants were cluster-randomised, by ECEC setting, to either a 12 week staff-led and expert-supported intervention or a waiting list control group. Results: The intervention group increased time spent in moderate- and vigorous intensity PA by 10 min/day (95% CI = 3, 18; P=0.01), took 1909 more steps per day (95% CI = 1130, 2688; P˂0.01) and reduced sedentary time with 14min/day (95% CI = -27, -1; P=0.04) compared to the control group. The intervention group had a 2.4 higher odds (95% CI = 1.05, 5.7; P = 0.04) of meeting the PA recommendations compared to the control group at follow-up. Conclusions: Our results show that a flexible staff-led and expert-supported multicomponent PA intervention can increase total PA level, moderate- and vigorous intensity PA and reduce time spent sedentary in three to four-year old children during their stay in ECEC settings.Trial registration: The trial was retrospectively registered on September 19, 2020 and available online at ClinicalTrials.gov: No. NCT04555746

Authors: Bi Yonghua , Li Jindong , Bai Liangliang , Han Xinwei , Ren Jianzhuang
Published: October 2020

Background: Endoscopic removal is the most common method for removal of tracheal stents. Few studies have reported the technique of fluoroscopy-guided stent removal for tracheal fistula and tracheal stenosis. We aimed to study the safety and efficacy of fluoroscopy-guided stent removal as well as the optimal duration for stent usage.Methods: We conducted a retrospective analysis of 152 patients who underwent fluoroscopy-guided stent removal from January 2011 to June 2017. Reasons for stent implantation were tracheal fistula in 85 patients (TF group), and tracheal stenosis in 67 patients (TS group). All patients underwent tracheal CT scans before stent removal and during follow up. The technical success rate, complications, and survival rate were compared between the two groups.Results: The technical success rate of stent removal was 98.9% and 97.4%, respectively for the TF and TS group. Removal was routine for half of patients, and in the remainder, excessive granulation tissue was the common indications for stent removal, which was found after stenting at 142.1±25.9 days in the TF group, and at 89.9±15.0 day in the TS group. The total incidence of complications was 21.1% and 22.4%, respectively, for the TF and TS groups. Perioperative death occurred in one patient in the TF group, and two patients in the TS group. Recurrence of fistula or stenosis requiring re-stenting was the most comment complication in both groups. The 0.5-, 3-, 6-year survival rates were 90.3%, 59.6%, and 36.1% for TF group, and 80.4%, 75.7%, 75.7% for TS group.Conclusions: Fluoroscopic removal of tracheal stents is safe and effective for both tracheal fistula and tracheal stenosis, with no significant difference in outcomes. Clinicians should pay attention to the risk of hemoptysis for patients with malignant tumors and a combination with endoscopic hemostasis may help improve its safety.
Distinct clinicopathological differences between early gastric cardiac and non-cardiac carcinomas: A single-center retrospective study of 329 radical resection cases

Published: October 2020

BackgroundEarly gastric carcinoma is heterogeneous and can be divided into early gastric cardiac carcinoma (EGCC) and early gastric non-cardiac carcinoma (EGNCC) groups. At present, differences in clinicopathology remains obscure between EGCC and EGNCC fundus-corpus and antrum-angularis-pylorus subgroups, especially between EGCC with and without oesophageal invasion.MethodsIn this study, we studied 329 consecutive early gastric carcinoma radical gastrectomies with 70 EGCCs and 259 EGNCCs.ResultsCompared to the EGNCC antrum-angularis-pylorus (n=181), but not fundus-corpus (n=78), sub-group, EGCC showed significantly older age, lower prevalence of the grossly depressed pattern, better tumor differentiation, higher percentage of tubular/papillary adenocarcinoma, but lower frequency of mixed poorly cohesive carcinoma with tubular/papillary adenocarcinoma, and absence of lymph node metastasis (LNM) in tumors with invasion up to superficial submucosa (SM1). In contrast, pure poorly cohesive carcinoma was less frequently seen in EGCCs than in EGNCCs, but mixed poorly cohesive carcinoma with tubular/papillary adenocarcinomas was significantly more common in the EGNCC antrum-angularis-pylorus sub-group than in any other group. No significant differences were found between EGCC and EGNCC sub-groups in gender, tumor size, H. pylori infection rate, and lymphovascular/perineural invasion. EGCC with oesophageal invasion (n=22), compared to EGCC without (n=48), showed no significant differences in the H. pylori infection rate and oesophageal columnar, intestinal, or pancreatic metaplasia, except for a higher percentage of the former in size > 2 cm and tubular differentiation.ConclusionsThere exist distinct clinicopathologic differences between EGCC and EGNCC sub-groups; EGCC was indeed of gastric origin. Further investigations with larger samples are needed to validate these findings.

Background: Alcohol consumption is associated with different types of illnesses; particularly heavy episodic drinking is one of the risk factors for the disease burden of alcohol intake. The aim of the study was to assess the prevalence of heavy episodic drinking and associated factors in Arba Minch Health and Demographic Surveillance Site (HDSS).Methods: A community-based cross-sectional study was conducted in 2017 among adult residents of Arba Minch HDSS. Using Arba Minch HDSS database, 3368 individuals were selected by simple random sampling techniques. From WHO STEPS instruments, step one was applied for this study. Variables with a p-value of less than 0.10 for bivariate analysis entered into a multivariable logistic regression model to outline the independent predictors of the heavy episodic drinking. To assess the presence of an association between dependent and independent variables, a p-value of less than 0.05 was considered.Results: The prevalence of heavy episodic drinking was 13.7% (95% CI: 12.6–14.9). The study has shown that heavy episodic drinking was significantly associated with occupation (daily laborer [AOR=0.49; 95% C.I: 0.29–0.85] and housewives [AOR=0.63; 95% C.I: 0.45–0.88] compared with farmers), wealth index (2nd quintiles [AOR =0.55; 95% C.I: 0.41–0.74) and 3rd quintiles [AOR = 0.66; 95% C.I: 0.46–0.93] compared with 1st quintiles), and climatic zone (midland [AOR=1.80;95% CI: 1.11–2.93), highland [AOR=1.95;95% CI: 1.19–3.18] compared with lowland). In addition, tobacco use [AOR=4.28;95% CI: 3.38–5.43], and khat use [AOR=4.75; 95% CI: 2.66–8.50) were also associated with heavy episodic drinking among the study participants. Conclusions: More than one in ten adults reported heavy episodic drinking in the study area. Intervention programs that aim to prevent heavy episodic drinking should be designed appropriately for individuals from lower wealth status, and for highlander.

Published: October 2020

Background : In clinical practice, fluctuating vision or decreased quality of vision is a common complaint in dry eye patients. Our study was designed to investigate the change in dynamic optical quality in dry eye patients after the use of artificial tears. Methods : Fifty-nine patients with dry eye disease (DED) and 31 healthy age- and sex-matched control subjects were included in this prospective case-control study. Clinical evaluation of the ocular surface included Ocular Surface Disease Index (OSDI), tear film break-up time (TBUT), lipid layer thickness (LLT), and Schirmer I test. DED patients were divided into two groups, mild (31 patients) and severe (28 patients). The optical quality of the tear film was measured with the Optical Quality Analysis System (OQAS) using the mean objective scatter index (mean OSI), standard deviation of objective scatter index (SD-OSI) and modulation transfer function cut-off (MTF cut-off). After baseline examinations, one drop of artificial tears (ATs, carboxymethylcellulose ophthalmic solution, 0.5%) was instilled in both eyes, and optical quality parameters were measured again at 5 and 30 minutes following application of ATs. Results: At baseline, the mean OSI was higher in the DED group (0.95 ± 0.54) than in controls (0.54 ± 0.23, P <0.001). The SD-OSI was also significantly increased in DED patients (0.44 ± 0.71) compared to control subjects (0.12 ± 0.06, P =0.003). Five minutes after AT instillation, mean OSI and SD-OSI decreased significantly in severe DED patients (P =0.044; P =0.018), remained unchanged in mild DED patients, and increased in the control group ( P =0.019; P <0.001). Thirty minutes after AT instillation, no significant difference in optical quality parameters was observed among the three groups. Conclusion : The effect of ATs on optical quality in patients with DED may differ according to the severity of the disease. Measurement of optical quality might be a promising tool to evaluate the effects of various ATs and possibly individualize treatment in DED patients.

Published: October 2020

Background: Training has been found effective in improving healthcare professionals’ knowledge, confidence, and skills in conducting advance care planning (ACP). However, the association between training and its actual practice in the clinical setting has not been well demonstrated. To fill this gap, this paper examines the association between their readiness for ACP, in terms of perceived relevancy of ACP with their clinical work, attitudes toward and confidence and willingness to perform it, based on the Theory Planned Behavior and relevant training experiences.Methods: An online survey about experiences about ACP of healthcare professionals, including physicians, nurses, social workers, and allied healthcare professionals, currently working in hospital and community care in Hong Kong was conducted. Results: Of 250 respondents, approximately half (51.6%) had received ACP-related training. Those with relevant training reported significantly more positive in the perceived clinical relevance, willingness, and confidence in conducting ACP and different levels of agreement with 19 out of the 25 statements in a questionnaire about attitudes toward ACP than those without (ps ≤ 0.001–0.05). Respondents who received training only in a didactic format reported a significantly lower level of confidence in conducting ACP than did others who received a blended mode of learning (p = 0.012). Notwithstanding significant differences between respondents with and without relevant training, respondents generally acknowledged their roles in initiating conversations and appreciated ACP in preventing decisional conflict in surrogate decision-making regardless of their training experience.Conclusions: This paper revealed the association between training and higher level of readiness toward ACP among healthcare professionals. The findings showed that training is a predictor of their readiness for ACP in terms of perceived relevancy, willingness, and confidence. Those who had received training were less likely to consider commonly reported barriers such as time constraints, cultural taboos, and avoidance among patients and family members as hindrances to ACP implementation.

Published: October 2020

Background: Breast cancer is the most common cancer among women in China. Amplification of the Human epidermal growth factor receptor type 2 (HER2) gene is present and overexpressed in 18–20% of breast cancers and historically has been associated with inferior disease-related outcomes. There has been increasing interest in de-escalation of therapy for low-risk disease. This study analyzes the cost-effectiveness of Doxorubicin/ Cyclophosphamide/ Paclitaxel/ Trastuzumab (AC-TH) and Docetaxel/Carboplatin/Trastuzumab(TCH) from payer perspective over a 5 year time horizon.Methods: A half-cycle corrected Markov model was built to simulate the process of breast cancer events and death occurred in both AC-TH and TCH armed patients. Cost data came from studies based on a Chinese hospital. One-way sensitivity analyses as well as second-order Monte Carlo and probabilistic sensitivity analyses were performed.The transition probabilities and utilities were extracted from published literature, and deterministic sensitivity analyses were conducted.Results:We identified 41 breast cancer patients at Hangzhou First People’s Hospital, among whom 15(60%) had a partial response for AC-TH treatment and 13 (81.25%) had a partial response for TCH treatment.No cardiac toxicity was observed. Hematologic grade 3 or 4 toxicities were observed in 1 of 28 patients.Nonhematologic grade 3 or 4 toxicities with a reverse pattern were observed in 6 of 29 patients. The mean QALY gain per patient compared with TCH was 0.25 with AC-TH, while the incremental costs were $US13,142.The incremental cost-effectiveness ratio (ICER) of AC-TH versus TCH was $US 52,565 per QALY gained.Conclusions: This study concluded that TCH neoadjuvant chemotherapy was feasible and active in HER2-overexpressing breast cancer patients in terms of the pathological complete response, complete response, and partial response rates and manageable toxicities.
Responses of forest carbon and water coupling to thinning treatments from leaf to stand scales in a young montane pine forest
Authors: Wang Yi , Campo Antonio D. del , Wei Xiaohua , Winkler Rita , Liu Wanyi , Li Qiang
Published: October 2020

Background
Water-use efficiency (WUE) represents the coupling of forest carbon and water. Little is known about the responses of WUE to thinning at multiple spatial scales. The objective of this research was to use field measurements to understand short-term effects of two thinning treatments (T1: 4,500 stems ha -1 ; and T2: 1,100 stems ha -1 ) and the control (NT:27,000 stems ha -1 )on WUE at the three spatial scales (leaf level: the ratio of leaf photosynthesis to leaf transpiration; tree-level: tree growth to tree transpiration; and stand level: net primary production (NPP)to stand transpiration) and intrinsic WUEi (the ratio of leaf photosynthesis to stomatal conductance at leaf-level; andNPP to canopy conductance at stand-level) in a 16-year old natural lodgepole pine forest. Leaf-level measurements were conducted in 2017, while tree- and stand-level measurements were conducted in both 2016 (the normal precipitation year) and 2017 (the drought year).

Results
The thinning treatments did not significantly affect the tree- and stand-level WUE in the normal year of 2016. However, the thinning significantly affected WUE in the drought year of 2017: T2 exhibited significantly higher tree-level WUE (0.49 mm 2 kg -1 ) than NT (0.08 mm 2 kg -1 ), and compared to NT, the stand-level WUE values in the thinned stands (T1 and T2) were significantly higher, with means of 0.31, 0.56 and 0.70 kg m -3 , respectively. However, the leaf-level and stand-level WUEi in the thinned stands in the drought year were significantly lower than those in the unthinned stands. No significant differences in the leaf-level WUE were found among the treatments in 2017. In addition, the thinning did not significantly change the WUE-VPD relationships at any studied spatial scale.

Conclusions
The thinning treatments did not cause significant changes in all studied WUE metrics in a normal year. However, their effects were significantly promoted under the drought conditions probably due to the decrease in soil water availability,demonstrating that thinning can improve WUE and consequently support forests to cope with the drought effects. The inconsistent results on the effects of the thinning on forest carbon and water coupling atthe spatial scales and the lack of the consistent WUE metrics constraint across-scale comparison and transferring of WUE.

Published: October 2020

Background: Nociceptin/orphanin FQ (N/OFQ) has been revealed to play bidirectional roles in orofacial pain modulation. Calcitonin gene-related peptide (CGRP) is a well-known pro-nociceptive molecule that participates in the modulation of orofacial pain. We aimed to determine the effects of N/OFQ on the modulation of orofacial pain and on the release of CGRP. Methods: Orofacial pain model was established by ligating springs between incisors and molars in rats for the simulation of tooth movement. The expression level of N/OFQ was determined and pain level scored in response to orofacial pain. Both agonist and antagonist of N/OFQ receptor were administered to examine their effects on pain and the expression of CGRP in trigeminal ganglia (TG). Moreover, gene therapy based on the overexpression of N/OFQ was delivered to validate the modulatory role of N/OFQ on pain and CGRP expression.Results: Tooth movement elicited orofacial pain and an elevation in N/OFQ expression. N/OFQ exacerbated orofacial pain and upregulated CGRP expression in TG, while UFP-101 alleviated pain and downregulated CGRP expression. N/OFQ-based gene therapy was successful in overexpressing N/OFQ in TG, which resulted in pain exacerbation and elevation of CGRP expression in TG. Conclusions: N/OFQ exacerbated orofacial pain possibly through upregulating CGRP.

Background: Lifestyle modifiable risk factors are a leading preventable cause of non-communicable diseases (NCDs). Amongst them, alcohol and tobacco consumption are the most important. Studies characterizing the prevalence of alcohol consumption in low-income countries are lacking. This study describes the prevalence of alcohol use in Burkina Faso and its associated factors separately for urban and rural residents.Methods: Data from the 2013 Burkina Faso World Health Organization (WHO) Stepwise approach to Surveillance (STEPS) were analyzed. The prevalence of alcohol consumption over the last 30 days were recorded and recoded into categories according to WHO recommendations: low alcohol consumption (<40g alcohol/day for men, <20g for women), mid alcohol consumption (between 40 and 59.9g/day for men and between 20 and 39.9g for women) and a heavy consumption (>60g/day for men and 40g for women). Logistic regression analyses identified factors associated with alcohol consumption use. Results: In the whole population 3,559 (75.8% [72.5 – 78.7]) were not consuming any alcohol, 614 (12.9% [10.9 – 15.3]) had a low alcohol consumption, 399 (8.5% [7.1 – 10.1]) a mid alcohol consumption and 120 (2.7% [2.0 – 3.7]) a high consumption. Age was associated with alcohol intake with a gradient effect, older people having a higher risk (AOR = 2.31 [1.68 – 3.17] for the 55 – 64 years old compared to 25 – 34 group). Tobacco consumption was also significantly associated with alcohol intake with a gradient effect, those with higher tobacco consumption being at higher risk of abusive alcohol intake. When analyzing the risk of having abusive consumption in those consuming alcohol, we found a highly significant gender effect, with males having an increased risk (AOR = 2.53 [1.38 – 4.68]).Conclusion: Our data showed an important burden of alcohol consumption in Burkina Faso with a strong relationship with age, gender and tobacco consumption and disparities across the different regions of Burkina Faso. To effectively reduce alcohol consumption in Burkina Faso, a comprehensive control program should consider these associated factors.
Research on simulation in radiography education: a scoping review protocol
Authors: Vestbøstad Mona , Karlgren Klas , Olsen Nina Rydland
Published: October 2020

Background: Today there are fewer opportunities for health care students and staff for skills training through direct patient contact. The World Health Organization therefore recommends learning about patient safety through hands-on experience and simulation. Simulation has the potential to improve skills through training in a controlled environment, and simulation has positive effect on knowledge and skills, and even patient related outcomes. Reviews addressing the use of simulation across the different radiography specialties are lacking. Further knowledge on simulation in radiography education is needed to inform curriculum design and future research. The purpose of this scoping review is to explore, map and summarize the extent, range and nature of published research on simulation in radiography education.Methods: We will follow the methodological framework for scoping reviews originally described by Arksey and O’Malley. We will search MEDLINE, Embase, Epistemonikos, The Cochrane Library, ERIC, Scopus, and sources of grey literature. A comprehensive search strategy for Ovid MEDLINE was developed in collaboration with a research librarian. An example of a full electronic search from the Ovid MEDLINE (1641 articles records, 09.01.2020) is provided and will be used to adapt the search strategy to each database. Two independent review authors will screen all abstracts and titles, and full-text publications during a second stage. Next, they will extract data from each included study using a data extraction form informed by the aim of the study. A narrative account of all studies included will be presented. We will present a simple numerical analysis related to the extent, nature and distribution of studies, and we will use content analysis to map the different simulation interventions and learning design elements reported. Any type of simulation intervention within all types of radiography specializations will be included. Our search strategy is not limited by language or date of publication. Discussion: An overview of publications on simulation in radiography education across all radiography specialties will help to inform future research and will be useful for stakeholders within radiography education using simulation, both in the academic and clinical setting.

Published: October 2020

Background: Postmenopausal osteoporosis (PMOP) is a global chronic and metabolic bone disease, which poses huge challenges to individuals and society. Ziyin Tongluo Formula (ZYTLF) has been proved effective in the treatment of PMOP. However, the material basis and mechanism of ZYLTF against PMOP have not been thoroughly elucidated.Methods: Online databases were used to identify the active ingredients of ZYTLF and corresponding putative targets. Genes associated with PMOP were mined, and then mapped with the putative targets to obtain overlapping genes. Multiple networks were constructed and analyzed, from which the key genes were selected. The key genes were imported to the DAVID database to performs GO and KEGG pathway enrichment analysis. Finally, AutoDock Tools and other software were used for molecular docking of core compounds and key proteins. Results: Ninety-two active compounds of ZYTLF corresponded to 243 targets, with 129 target genes interacting with PMOP, and 50 key genes were selected. Network analysis showed the top 5 active ingredients including quercetin, kaempferol, luteolin, scutellarein, and formononetin., and the top 50 key genes such as VEGFA, MAPK8, AKT1, TNF, ESR1. Enrichment analysis uncovered two significant types of KEGG pathways in PMOP, hormone-related signaling pathways (estrogen , prolactin, and thyroid hormone signaling pathway) and inflammation-related pathways (TNF, PI3K-Akt, and MAPK signaling pathway). Moreover, molecular docking analysis verified that the main active compounds were tightly bound to the core proteins, further confirming the anti-PMOP effects. Conclusions: Based on network pharmacology and molecular docking technology, this study initially revealed the mechanisms of ZYTLF on PMOP, which involves multiple targets and multiple pathways.

Published: October 2020

Backgrounds: Tolvaptan significantly increases urine volume in acute decompensated heart failure (ADHF); serum sodium level increases due to aquaresis in almost all cases. We aimed to elucidate clinical factors associated with hypernatremia in ADHF patients treated with tolvaptan.Methods: We enrolled 117 ADHF patients treated with tolvaptan in addition to standard therapy. We examined differences in clinical factors at baseline between patients with and without hypernatremia in the initial three days of hospitalization. Results: Systolic (p=0.045) and diastolic (p=0.004) blood pressure, serum sodium level (p=0.002), and negative water balance (p=0.036) were significantly higher and serum potassium level (p=0.026) was significantly lower on admission day in patients with hypernatremia (n=22). In multivariate regression analysis, hypernatremia was associated with low serum potassium level (p=0.034). Among patients with serum potassium level ≤3.8 mEq/L, the cutoff value obtained using receiver operating characteristic curve analysis, those with hypernatremia related to tolvaptan treatment showed significantly higher diastolic blood pressure on admission day (p=0.004).Conclusion: In tolvaptan treatment combined with standard therapy in ADHF patients, serum potassium level ≤ 3.8mEq/L may be a determinant factor for hypernatremia development. Among hypokalemic patients, those with higher diastolic blood pressure on admission may be carefully managed to prevent hypernatremia.

Published: October 2020

Background Despite the advancement of scientific research in the field of maternity care, midwives face challenges translating latest evidence into evidence-based practice (EBP) and express reticence towards leading practice change in clinical areas. This study aimed to explore midwifery leaders’ views on what factors help or hinder midwives’ efforts to translate latest evidence into everyday practice and consider them in relation to both the Capability, Opportunity, Motivation and Behaviour (COM-B) model and Theoretical Domains Framework (TDF).Methods This qualitative study formed part of a larger Action Research (AR) project that was designed to improve midwives’ EBP implementation capability. Data were obtained from eight Western Australian midwifery leaders who were employed in either managerial or executive positions within their organisation. Five midwives attended a focus group workshop and three opted for face-to-face interviews. Thematic analysis was used to code the transcribed data and group alike findings into sub-categories, which were collapsed to four major categories and one overarching core finding. These were mapped to a matrix combining the COM-B and TDF to establish the usability of these tools in midwifery contexts. Results Four major categories were developed from the data collected in this study. Three reported the hindrances midwives’ experienced when trying to initiate new EBPs: “For midwives, medical opposition and workplace culture are the biggest challenges”, “Fear can stop change: it’s personal for midwives” and “Midwives are tired of fighting the battle for EBP; they need knowledge and the confidence to bring about practice change.” The other major category highlighted factors midwives’ considered helpers of EBP: “Having stakeholder buy-in and strong midwifery leadership is a huge advantage.” When mapped to the TDF and COM-B, these findings provided valuable insight into the helpers of and hindrances to evidence-based practice in midwifery. Conclusion Midwives are motivated to initiate evidence-based change yet have limited knowledge of implementation processes or the confidence to lead practice change. Factors such as inter-disciplinary buy-in, clear instruction for midwives and support from midwifery leaders were considered beneficial to implementing practice change in clinical areas. The TDF when used in combination with the COM-B was deemed useful to midwives wanting to lead practice change projects in clinical areas.

Background Gut microbiota in humans and animals play an important role in health, aiding in digestion, regulation of the immune system and protection against pathogens. Changes or imbalances in the gut microbiota (dysbiosis) have been linked to a variety of local and systemic diseases, and there is growing evidence that restoring the balance of the microbiota by delivery of probiotic microorganisms can improve health. However, orally delivered probiotic microorganisms must survive transit through lethal highly acid conditions of the stomach and bile salts in the small intestine. Current methods to protect probiotic microorganisms are still not effective enough.Results We have developed a cell encapsulation technology based on the natural polymer, cellulose sulphate (CS) that protects members of the microbiota from stomach acid and bile. Here we show that six commonly used probiotic strains (5 bacteria and 1 yeast) can be encapsulated within CS microspheres. These encapsulated strains survive low pH in vitro for up to 4 hours without appreciable loss in viability as compared to their respective non-encapsulated counterparts. They also survive subsequent exposure to bile. The CS microspheres can be digested by cellulase in levels found in the human intestine, indicating one mechanism of release. Studies in mice that were fed CS encapsulated autofluorescing, commensal E. coli demonstrated release and colonization of the intestinal tract.Conclusion Taken together, the data suggests that CS microencapsulation can protect bacteria and yeasts from viability losses due to stomach acid, allowing the use of lower oral doses of probiotics and microbiota, whilst ensuring good intestinal delivery and release.

Background: The purpose of our study was to assess the frequency of occult foreign body aspiration (FBA) and to evaluate the diagnostic difficulties and therapeutic methods for these patients.Methods: Between May 2000 and May 2020, 3557 patients with the diagnosis of FBA were treated in our department. Thirty-five patients with occult FBA were included in this study. A retrospective analysis of medical records was performed.Results: Twenty-three male patients (65.7%) and 12 female patients (34.3%) were hospitalized due to occult FBA. The average age was 3.60 years (range 9 months-12 years). Most of the patients were younger than 3 years old (n=25, 71.4%). Coughing (n=35, 100%) and wheezing (n=18, 51.4%) were the main symptoms and signs. All the patients were found to have a FBA under the fiberoptic bronchoscope. The most common organic foreign bodies were peanuts (n=10) and the most common inorganic foreign bodies were pen caps (n=5). The extraction of foreign bodies under rigid bronchoscopy was applied successfully in 34 patients. Only one patient needed a surgical intervention.Conclusions: Occult FBA should always be considered in the differential diagnosis of chronic or recurrent respiratory diseases that are poorly explained, even in the absence of a previous history of aspiration.

Background: Strong evidence demonstrates that social support plays a key role in facilitating preventive health behaviors. The aim of the current study was to assess the effects of perceived social support on compliance with stay-at-home orders in response to a COVID-19 outbreak during the Persian New Year (Nowruz) holydays, since Nowruz holidays of 2020 coincided with the peak of the coronavirus epidemic in Iran. Methods: This cross-sectional survey was carried out based on phone interviews of 1073 adults aged over 18 years from 4 to 12 April 2020 in Mashhad, Khorasan-Razavi Province, as the second largest city of Iran. A systematic random sampling was carried out using fixed phone number lists provided by Telecommunication Company of Khorasan-Razavi Province. Phone interviews were carried out by trained interviewers from the Iranian Students Polling Agency (ISPA) at various times of the day. The survey included sociodemographic questions, perceived social support scale (MSPSS) and questions about self-isolation during the Nowruz holiday. Statistical analysis included Chi-square test, Mann-Whitney test and multivariate logistic regression.Results: 20.5% of participants reported poor compliance with stay at home orders during the first two weeks of Nowruz. Clear social gradients were not found in stay-at-home compliance. When controlling socio-demographic factors, perceived social support, interestingly, both fostered and hindered people’s compliance with stay at home orders, depending on the source of support from family members (OR=.874, 95% CI=.803, .950, p<.005), friends (OR=1.147, 95% CI=1.076, 1.222, p<.001) and a significant other person (OR=.926, 95% CI=.849, 1.010, p=.084).Conclusions: Public health messaging may need to emphasize the role that friends and families can play in helping to protect those in their friendship/family groups by promoting compliance with social distancing. Further in-depth studies are recommended to evaluate how this kind of messaging can most effectively encourage people to engage in social distancing practices.

Background: Feral swine (Sus scrofa) are highly invasive and threaten animal and public health in the Americas. Screwworm (Cochliomyia hominivorax) is listed by the World Organization for Animal Health as a notifiable infestation because myasis cases affect livestock, wildlife, and humans in endemic areas, and outbreaks can be of high socioeconomic consequence in regions where screwworm was eradicated. However, a knowledge gap exists on screwworm infestation of feral swine in South America, where screwworm is endemic. Here, we report infestation with screwworm in feral swine harvested in the Department of Artigas, where the Republic of Uruguay shares borders with Brazil and Argentina. Methods: Myiasis caused by the larvae of screwworm were identified in feral swine with the support and collaboration of a local feral swine hunting club over a three-year period in the Artigas Department of Uruguay. Harvested feral swine were examined for the presence of lesions where maggots causing the myiasis could be sampled and processed for taxonomic identification. The sites of myiasis on the body of infested feral swine and geospatial data for each case were recorded. Feral swine sex and relative size were recorded. Temperature and precipitation for the region were obtained from public sources.Results: Myiases caused by screwworms were recorded in 27 of 618 feral swine harvested. Cases detected in males over 40 kg were associated with wounds that, because of their location, were likely caused by aggressive dominance behavior between adult males. The overall prevalence of screwworm infestation in feral swine was associated with ambient temperature, but not precipitation. Case numbers peaked in the warmer spring and summer months. Conclusions: This is the first report for South America of myasis caused by screwworm in feral swine. In contrast to myasis in cattle that can reach deep into host tissues, screwworms in feral swine tended to cause superficial infestation. The presence of feral swine is a challenge to control screwworms in endemic areas. Screwworm populations maintained by feral swine may contribute to human cases in rural areas of Uruguay, which highlights the One Health importance of this invasive host species-ectoparasite interaction.

Background: Large-scale afforestation can significantly change the ground cover and soil physicochemical properties, especially the soil fertility maintenance and water conservation functions of artificial forests are very important in semi-arid mountain ecosystems. However, how different tree growth affect soil nutrient and soil physicochemical properties following afforestation and which is the best plantation tree species for improving soil fertility and water conservation functions remain largely unknown. Methods: This study investigated the soil nutrient contents of three plantations with different tree species (Larix principis-rupprechtii, Picea crassifolia, Pinus tabuliformis), soils and plant-soil feedbacks, as well as the interaction between soil physicochemical properties. Results: The results revealed that the leaf and litter layer strongly influence soil nutrient availability through biogeochemical processes: P. tabuliformis has higher organic carbon, ratio of organic carbon to total nitrogen (C:N) and organic carbon to total phosphorus (C:P) in the leaves and litter layer than L. principis-rupprechtii or P. crassifolia, suggesting that higher C:N and C:P hinder litter decomposition. As a result, the L. principis-rupprechtii and P. crassifolia plantation forests significantly improve soil nutrients and clay components than the P. tabuliformis plantation forest. Furthermore, the L. principis-rupprechtii and P. crassifolia plantation forests significantly improved the soil capacity, soil total porosity, and capillary porosity, decreased soil bulk density, and enhanced water storage capacity than the P. tabuliformis plantation forest. In conclusion, the results of this study showed that the strong link between plants and soil is tightly coupled to C:N and C:P, and there had a close correlation between soil particle size distribution and soil physicochemical properties. Conclusions: Therefore, our results recommend planting the L. principis-rupprechtii and P. crassifolia as the preferred tree species to enhance the soil fertility and water conservation functions, especially in semi-arid regions mountain forest ecosystems.

Published: October 2020

Background: Farrowing induction with prostaglandin F2 analogue cloprostenol is commonly used on commercial farms to manage the timing of farrowing. When labour induction is applied, the questions arise about possible side effects of such a hormonal intervention on physiological processes connected with labour and lactation, including colostral immunity. Results: In this study, immune cells composition, lysozyme concentration, complement bacteriolytic activity and proinflamatory (GM-CSF2, IL-1β, IL-6, a TNFα) and anti-inflammatory (IL-4, IL-10, TGFβ1 a TGFβ2) cytokines were measured in colostrum samples from sows farrowing naturally (NP) and from sows with farrowing induced using cloprostenol administration on day 113 of gestation (IP). A significantly higher proportion of lymphocytes was found in colostrum of induced sows compared to colostrum of non-induced sows. No significant differences between NP and IP were found in complement activity, in the proportions of granulocytes, macrophages and lymphocyte subpopulations. Lower lysozyme concentration and higher IL-1β, IL-6, TGFβ1 and TNFα concentrations were found in IP sow colostrum compared to colostrum from NP sows. Conclusions: An increased proportion of colostral lymphocytes can positively influence the cellular immunity transmission from sow to her offspring. On the other hand, a lower lysozyme concentration can adversely affect newborn’s intestinal immunity, as well as changes in cytokine concentrations can have an adverse effect on newborn piglet intestinal epithelium development and its defence function.
