В продолжение биомониторинговых исследований ртути на территории Крымского полуострова, направленных на реализацию системного подхода к изучению ее распределения между компонентами биосферы и разработки региональных экологических нормативов этого и других металлов, проведено определение содержания ртути в эпифитных лишайниках, являющихся природными планшетами атмосферной эмиссии тяжелых металлов. Цель: определить и оценить содержание ртути в пробах эпифитных лишайников, отобранных в центральном, южном, юго-восточном и восточном регионах Крымского полуострова. Методы. Содержание ртути в лишайниках видов Xanthoria parietina, Evernia prunastri и Evernia mesomorpha определяли атомно-абсорбционным методом с использованием анализатора ртути с зеемановской коррекцией неселективного поглощения «РА-915М», пиролитической приставки «ПИРО-915+» и пакета программ RA915Р в МИНОЦ «Урановая геология» Томского политехнического университета, и методом масс-спектрометрии с индуктивно связанной плазмой в аккредитованном химико-аналитическом центре «Плазма» (г. Томск). Результаты. Содержание ртути в эпифитных лишайниках, отобранных преимущественно на заповедных территориях южного региона Крыма, а также в парковых зонах городов его центрального, юго-восточного и восточного регионов и вблизи очистных сооружений варьировало в пределах от 0,054 до 0,306 мкг/г и не отличалось от фоновых значений содержания ртути в лишайниках на других территориях Российской Федерации. В то же время наблюдалась существенная неоднородность в территориальном распределении ртути: в лишайниках парковых зон на территории городов ее содержание колебалось в пределах 0,063–0,088 мкг/г, а в горных и предгорных районах южного Крыма было выше в 2 раза. Это может быть связано с геоморфологическими и геохимическими особенностями Главной гряды (глубинные разломы ортогональной системы с ртутными рудопроявлениями и зонами геодинамической активности), а также ее барьерной функцией для воздушных масс, насыщенных морскими аэрозолями, содержащими ртуть. Помимо этого, как свидетельствуют данные моделирования экспертной группы Конвенции LRTAP, существенный вклад может вносить трансграничный перенос ртути. Вариабельность содержания ртути в лишайниках на условно фоновых территориях и интенсивное технологическое развитие Крыма диктуют необходимость дифференцированного подхода к оценке экологической ситуации в отношении этого глобального и опасного загрязнителя на различного типа территориях Крымского полуострова.

Understanding Participant’s Behaviour in Massively Open Online Courses
Authors: Poellhuber Bruno , Roy Normand , Bouchoucha Ibtihel 
Published: July 2019

As the offer of Massive Open Online Courses (MOOCs) continues to grow around the world, a great deal of MOOC research has focused on their low success rates and used indicators that might be more appropriate for traditional degree-seeking students than for MOOC learners, who, because of the openness of MOOCs, represent a more diverse clientele who exhibit different characteristics and behaviours. In this study, conducted in a French MOOC that is part of the EDUlib initiative, we systematically classified MOOC user profiles based on their behaviour in the open-source learning management system (LMS) — in this case, Sakai — and studied their survival in the MOOC. After formatting the logs in ordinal variables in order to reflect a continuum of participation central to the behavioural engagement concept (Fredricks, Blumenfeld, & Paris, 2004), we incrementally executed a two-step cluster analysis procedure that led us to identify five different user profiles, after having manually excluded Ghots : Browser, Self-Assessor, Serious Reader, Active-Independent, and Active-Social. These five profiles differed both qualitatively and quantitatively on the continuum of engagement, and a significant proportion of the less active profiles did not drop out of the MOOC. Our results confirm the importance of social behaviours, as in recent typologies, but also point out a new Self-Assessor category. The implications of these profiles for MOOC design are discussed.

Case:A 24-year-old female diagnosed with fibroblastic osteosarcoma of the patella underwent a total patellectomy and surgical reconstruction with a large bone–tendon allograft of the extensor mechanism and adjuvant chemotherapy. At 5 years' postoperative, the patient has adequate disease control and excellent joint function.Conclusions:Reconstruction with an extensor mechanism allograft is an appropriate alternative for patients with malignant patella tumors without tumor contamination of the joint, allowing for satisfactory knee function and disease control.
Genome-wide analysis of the citrus B3 superfamily and their association with somatic embryogenesis

Published: July 2019

Abstract
Background

In citrus, genetic improvement via biotechnology is hindered by the obstacle of in vitro regeneration via somatic embryogenesis (SE). Although a few of B3 transcription factors are reported to regulate embryogenesis, little is known about the possible roles of B3 superfamily during SE especially in citrus.

Results

In this study, a total of 72 (CsB3) and 69 (CgB3) putative B3 superfamily members were identified in the sweet orange (Citrus sinensis) and pummelo (C. grandis) genomes, respectively, each comprised four gene families and 14 phylogenetic classes. The B3 genes were unevenly distributed over citrus chromosomes and other non-anchored scaffolds. Genome duplication analysis indicated that the segmental and tandem duplication events have significantly contributed to the expansion of the citrus B3 superfamily. The evolutionary relationships among the B3 family members and their putative functions were deduced based on the results of phylogenetic analysis. Furthermore, transcriptomic analysis showed that citrus B3 genes have differential expression levels in various tissues, suggesting distinct biological roles of different members. Expression analysis revealed that the B3 superfamily members showed four types of expression profiles during SE in citrus and may play functional roles during SE, especially at late SE stages. Of them, CsARF19 is specifically expressed in sweet orange and at markedly higher levels in the embryogenic callus (EC), implying its possible involvement in EC initiation.

Conclusions

This study provides a genome-wide analysis of citrus B3 superfamily, including its genome organization, evolutionary features and expression profiles, which contributes to a better understanding of the B3 genes in citrus and their association with SE.
Outcomes after traffic injury: mental health comorbidity and relationship with pain interference

Published: July 2019

Abstract
Background

Mental health symptoms, like depressive mood (DM) and post-traumatic stress (PTS), and pain-related disability, known as pain interference (PI) often co-occur following traffic injury and their comorbidity can complicate recovery. Clarification is required on mental health comorbidity and relationships with PI, to enhance care and outcomes after a traffic injury.

Methods

2019 adults sustaining minor-to-moderate traffic injury were recruited within 28 days post-injury and assessed using phone interviews at 1, 6 and 12-months post-injury. Trajectories of DM, PTS and PI were established and relationships between DM, PTS and PI trajectories were explored using dual trajectory modelling. Predictors of mental health trajectories were also investigated.

Results

Up to five typical post-trauma trajectories were identified for DM, PTS and PI. Most people were in a resilient mental health trajectory (over 60%, DM or PTS), or in a chronic pain disability trajectory (almost 60%, PI) 12 months post-injury. While recovery/resilient mental health trajectories were strongly interrelated (73.4% joint probability and >94% conditional probabilities), DM/PTS comorbidity in chronic trajectories was not straightforward, suggesting a possibly asymmetric relationship. That is, persistent DM was more likely associated with persistent PTS (90.4%), than vice versa (31.9%), with a 22.5% probability that persistent PTS was associated with none or milder depression (i.e. following a recovery/resilient DM trajectory). An asymmetrical relationship was also found between mental health and PI. The majority of those with persistent PI were likely to be in a recovery/resilient DM/PTS trajectory (almost 70%), but those in a non-resilient DM/PTS trajectory showed a high risk of persistent PI. Predictors of non-resilient mental health trajectories included poorer pre-injury health and social support, and shared factors like acute psychological distress and pain catastrophizing.

Conclusions

Strong interrelations were confirmed between mental health problems and pain disability following traffic injury. However, persistent depression was more strongly linked to persistent post-traumatic stress, than vice versa. Persistent pain disability was only linked with persistent mental health symptoms in vulnerable subgroups. Early psychiatric/psychological interventions should target elevated psychological distress and negative appraisals in vulnerable individuals, to reduce mental health morbidity/comorbidity and chronic pain disability.

Authors: Gao Wenjie , Zhang Xinliang , Zhu Jinwen , Chang Zhen , Li Yibing , Wang Xiaodong , Hao Dingjun 
Published: July 2019

Abstract
Background
Pre-existing degeneration of adjacent segment is an important risk factor for adjacent segment degeneration (ASD), but limited and controversial studies have addressed its management.
Methods
Patients with symptomatic degeneration of the L5/S1 segment warranting surgical interference and severe asymptomatic degeneration of the L4/5 segment were retrospectively analyzed. Among them, those who underwent interbody fusion in the causative (L5/S1) segment and distraction of the intervertebral space and facet fusion in the adjacent L4/5 segment were included as Group A (n=103). Patients who underwent interbody fusion in both L5/S1 and L4/5 segments were included as Group B (n=81). Clinical and radiographic outcomes were evaluated.
Results
Mean follow-up was 58.5 months (range, 48-75 m). No significant difference in clinical outcomes or the incidence of adjacent segment degeneration in L3/4 segment was found between Groups A and B. Compared with Group B, less bleeding (315±84 vs. 532±105 ml), shorter operation time (107±34 vs. 158±55 min) and lower costs (13,830±2640 vs. 16,020±3380 US$) were found in Group A (P<0.05). In Group A, disc height ratio (DHR) of L4/5 segment was significantly increased from preoperative value of 0.40±0.13 to last follow-up value of 0.53±0.18 (P<0.05), while the degree of canal stenosis (DCS) was decreased from preoperative value of 34.3±11.2% to last follow-up value of 15.9±9.3% (P<0.05).
Conclusions
This new method could be effective in treating severe asymptomatic pre-existing degeneration of adjacent segment in lumbar spine.

Published: July 2019

Abstract
Background
Community Health Representatives (CHRs) overcome health disparities in Native communities by delivering home care, health education, and community health promotion. The Navajo CHR Program partners with the non-profit COPE, to provide home-based outreach to Navajo clients living with diabetes. COPE trains CHRs on Motivational Interviewing and provides CHRs with culturally-appropriate education materials. The objective of this research is to understand the participant perspective of the CHR-COPE collaborative outreach through exploring patient-reported outcomes (PROs) using a qualitative methods evaluation.

Methods
Seven COPE clients were selected to participate in semi-structured interviews one year after finishing COPE to explore their perspective and experiences. Qualitative interviews were recorded, transcribed, and coded to identify themes.

Results
Through qualitative interviews, clients displayed that health education delivered by CHRs facilitated lifestyle changes by helping them understand key health indicators and setting achievable goals through the use of accessible material and encouragement. Clients felt comfortable with CHRs who respected traditional practices and made regular visits. Clients also appreciated when CHRs educated their family members, who in turn were better able to support the client in their health management. Finally, CHRs who implemented the COPE intervention helped patients who were unable to regularly see a primary care doctor for critical care and support in their disease management.

Conclusion
The COPE-CHR collaboration facilitated trusting client-CHR relationships and allowed clients to better understand their diagnoses. Further investment in materials that respect traditional practices and aim to educate clients' families may foster these relationships and improve health outcomes.

Abstract
Background: Fall prevention exercise programmes are known to be effective, but access to these programmes is not always possible. The use of eHealth solutions might be a way forward to increase access and reach to a wider population. In this feasibility study the aim was to explore the choice of programme, adherence, and self-reported experiences comparing two exercise programmes – a digital programme and a paper booklet.
Methods: A participant preference trial of two self-managed fall prevention exercise interventions. Community-dwelling adults aged 70 years and older exercised independently for four months after one introduction meeting. Baseline information was collected at study start at the introduction meeting, including a short introduction of the exercise programme, a short physical assessment and completion of questionnaires. During the four months intervention period, participants self-reported their performed exercises in an exercise diary. At a final meeting, questionnaires about their experiences as well as post-assessments were completed. For adherence analyses data from diaries were used and four subgroups for different levels of participation were compared. Exercise maintenance was followed up with a survey 12 months after study start.
Results: Sixty-seven participants, with a mean age of 77±4 years were included, 72% were women, and 43% chose the digital programme. Attrition rate was 17% in the digital programme group and 37% in the paper booklet group. In both groups 50-59% reported exercise at least 75% of the intervention period. The only significant difference for adherence was in the subgroup that completed ≥75% of exercise duration, the digital programme users exercised more minutes per week (p=.001). Participants in both groups were content with their programme but digital programme users reported a significantly higher (p=.026) degree of being content, and feeling supported by the programme (p=.044). At 12 months follow-up 67% of participants using the digital programme continued to exercise regularly compared with 35% for the paper booklet (p=.036).
Conclusions: This study showed that both the digital and paper programme could be used as a self-managed, independent fall prevention exercise programme. The digital programme seems to facilitate long-term maintenance in regular exercise.

Abstract
Background

Esophagectomy is a major surgical procedure with a high degree of catabolic and postsurgical inflammatory response that conditions a high morbidity and a significant mortality. Enteral administration of ω-3 fatty acids has been seen to be effective although its use is limited due to tolerance. There are few clinical trials with ω-3 fatty acids parenterally in these patients, so we propose to investigate the effect of combining a lipid emulsion rich in fish oil with the standard enteral nutrition support.

Methods

Prospective, single-center, randomized, double-blind study in patients diagnosed with esophageal cancer and after esophagectomy treated with a lipid emulsion rich in ω-3 fatty acid emulsion or a mixture of ω-6 long chain triglycerides (LCT) / short chain triglycerides (MCT) 50%. After surgery, these emulsions will be added to the standard nutritional support in continuous infusion until complete 5 days of treatment. Patients will be randomized 1:1:1 in Group A 0,4g/kg/day of lipid emulsion rich in fish oil; Group B 0,8g/kg/day of lipid emulsion rich in fish oil and Group C 0,8g/kg/day of LCT/MCT emulsion.

The main objective is to determine whether the administration for 5 days of intravenous lipid emulsions rich in ω-3 fatty acids in patients after esophagectomy is effective in normalizing the interleukin-6 (IL6) compared with LCT/MCT emulsions, and if 0,8 g/kg/day dose is more effective than 0,4g/kg/day. Secondary outcomes include other inflammatory markers as C reactive protein (CRP), tumor necrosis factor alpha (TNF-a) and interleukin-10 (IL-10), and parameters of morbidity, safety, nutrition and mortality.

Samples will be collected at the moment of surgery indication and on days 0, 1, 3, 5 and 21 to determine inflammatory, nutritional, hepatic and security parameters. In addition, clinical follow-up throughout the hospital stay and up to one year after surgery.

Discussion

There are few studies of fatty acids ω-3 administered via parenteral in oesophagectomized patients. This study proposes to investigate the effect of combining fish-oil lipid emulsions administered via parenteral with enteral nutrition support, implying benefits such as: fast incorporation of lipids to the cellular membranes and to the inflammatory cascade, and the use of only one pharmaconutrient.

Abstract
Background

Pulmonary diseases are a common and costly cause of 30-day readmissions. In this study we analysed the association between sex and the risk of readmission in a cohort of patients admitted to the hospital for COPD exacerbation and other major pulmonary diseases. The goal is to tailor disease management programs to improve clinical outcomes and prevent waste in resource use.

Methods

This was a retrospective cohort study based on administrative data collected in the Veneto Region in 2016. We included 15,069 hospital admissions among residents aged ≥ 65 years for DRGs of the most common disorders of the respiratory system: bronchitis and asthma, pneumonia, pulmonary edema, respiratory failure, and COPD. Multilevel logistic regressions were performed to test the association between 30-day hospital readmission and sex, adjusting for confounding factors.

Results

For bronchitis and asthma, male patients had a twofold significantly higher odd of 30-day readmission than male patients (aOR, 2.07; 95% CI, 1.11-3.87). The odd of readmission for men was also significantly higher for pneumonia (aOR, 1.40; 95% CI, 1.13-1.72), for pulmonary edema and respiratory failure (aOR, 1.28; 95% CI, 1.05-1.55), and for COPD (aOR, 1.34; 95% CI, 1.00-1.81).

Conclusions

This study found that male sex is a major risk factors for readmission in patients aged more than 65 years with a primary pulmonary diagnosis. More studies are needed to understand the underlying determinants of this phenomena and to provide targets for future interventions
