Contextual factors favouring success in the accreditation process in Colombian hospitals: a nationwide observational study
Authors: Zapata-Vanegas Mario A. , Saturno-Hernández Pedro J. 
Published: August 2020

Abstract
Background
To identify context factors associated with and predicting success in the hospital accreditation process, and to contribute to the understanding of the relative relevance of context factors and their organizational level in the success of QI initiatives.

Methods
Analytical study of cases and controls in a sample of hospitals of medium and high complexity in Colombia. Cases (n = 16) are accredited hospitals by the time of preparation of the study (2016) and controls (n = 38) are similar facilities, which have not succeeded to obtain accreditation. Eligibility criteria for both groups included complexity (medium and high), having emergency services, an official quality assurance license, and being in operation for at least 15 years. Besides eligibility criteria, geographical location, and type of ownership (public/private) are used to select controls to match cases.
Context measures are assessed using a survey instrument based on the MUSIQ model (“Model for Understanding Success in Quality”) adapted and tested in Colombia. Statistical analysis includes descriptive measures for twenty-three context factors, testing for significant statistical differences between accredited and non-accredited hospitals, and assessing the influence and strength of association of context factors on the probability of success in the accreditation process. A multivariate model assesses the predictive probability of achieving accreditation.

Results
Eighteen (78.3%) of the twenty-three context factors are significantly different when comparing cases and controls hospitals, particularly at the Microsystem level; all factors are statistically significant in favor of accredited hospitals. Five context factors are strongly associated to the achievement of accreditation but in the logistic multivariable model, only two of them remain with significant OR, one in the Macrosystem, “Availability of economic resources for QI” (OR: 22.1, p: 0,005), and the other in the Microsystem, “Involvement of physicians” (OR: 4.9, p: 0,04).

Conclusion
This study has applied an instrument, based on the MUSIQ model, which allows assessing the relevance of different context factors and their organizational level in hospitals, to explain success in the accreditation process in Colombia. Internal macrosystem and microsystem seem to be more relevant than external environment factors.
Implementing recommendations for inpatient healthcare provider encouragement of cardiac rehabilitation participation: development and evaluation of an online course
Authors: Santiago de Araújo Pio Carolina , Gagliardi Anna , Suskin Neville , Ahmad Farah , Grace Sherry L. 
Published: August 2020

Abstract
Background
A policy statement recommending that healthcare providers (HCPs) encourage cardiac patients to enroll in cardiac rehabilitation (CR) was recently endorsed by 23 medical societies. This study describes the development and evaluation of a guideline implementation tool.

Methods
A stepwise multiple-method study was conducted. Inpatient cardiac HCPs were recruited between September 2018–May 2019 from two academic hospitals in Toronto, Canada. First, HCPs were observed during discharge discussions with patients to determine needs. Results informed selection and development of the tool by the multidisciplinary planning committee, namely an online course. It was pilot-tested with target users through a think-aloud protocol with subsequent semi-structured interviews, until saturation was achieved. Results informed refinement before launching the course. Finally, to evaluate impact, HCPs were surveyed to test whether knowledge, attitudes, self-efficacy and practice changed from before watching the course, through to post-course and 1 month later.

Results
Seven nurses (71.4% female) were observed. Five (62.5%) initiated dialogue about CR, which lasted on average 12 s. Patients asked questions, which HCPs could not answer. The planning committee decided to develop an online course to reach inpatient cardiac HCPs, to educate them on how to encourage patients to participate in CR at the bedside. The course was pilot-tested with 5 HCPs (60.0% nurse-practitioners). Revisions included providing evidence of CR benefits and clarification regarding pre-CR stress test screening. HCPs did not remember the key points to convey, so a downloadable handout was embedded for the point-of-care. The course was launched, with the surveys. Twenty-four HCPs (83.3% nurses) completed the pre-course survey, 21 (87.5%) post, and 9 (37.5%) 1 month later. CR knowledge increased from pre (mean = 2.71 ± 0.95/5) to post-course (mean = 4.10 ± 0.62; p ≤ .001), as did self-efficacy in answering patient CR questions (mean = 2.29 ± 0.95/5 pre and 3.67 ± 0.58 post; p ≤ 0.001). CR attitudes were significantly more positive post-course (mean = 4.13 ± 0.95/5 pre and 4.62 ± 0.59 post; p ≤ 0.05). With regard to practice, 8 (33.3%) HCPs reported providing patients CR handouts pre-course at least sometimes or more, and 6 (66.7%) 1 month later.

Conclusions
Preliminary results support broader dissemination, and hence a genericized version has been created (http://learnonthego.ca/Courses/promoting_patient_participation_in_CR_2020/promoting_patient_participation_in_CR_2020EN/story_html5.html). Continuing education credits have been secured.
Haplotyping by linked-read sequencing (HLRS) of the genetic disease carriers for preimplantation genetic testing without a proband or relatives

Published: August 2020

Abstract
Background
In order to mitigate the risk of allele dropout (ADO) and ensure the accuracy of preimplantation genetic testing for monogenic disease (PGT-M), it is necessary to construct parental haplotypes. Typically, haplotype resolution is obtained by genotyping multiple polymorphic markers in both parents and a proband or a relative. Sometimes, single sperm typing, or tests on the polar bodies may also be useful. Nevertheless, this process is time-consuming. At present, there was no simple linkage analysis strategy for patients without affected relatives.

Method
To solve this problem, we established a haplotyping by linked-read sequencing (HLRS) method without the requirement for additional relatives. First, the haplotype of the genetic disease carriers in the family was constructed by linked-read sequencing, and then the informative single nucleotide polymorphisms (SNPs) in upstream and downstream mutation region were selected to construct the embryo haplotype and to determine whether the embryo was carrying the mutation. Two families were selected to validate this method; one with alpha thalassemia and the other with NDP gene disorder.

Results
The haplotyping by linked-read sequencing (HLRS) method was successfully applied to construct parental haplotypes without recruiting additional family members; the method was also validated for PGT-M. The mutation carriers in these families were sequenced by linked-read sequencing, and their haplotypes were successfully phased. Adjacent SNPs of the mutation gene were identified. The informative SNPs were chosen for linkage analyses to identify the carrier embryos. For the alpha thalassemia family, a normal blastocyst was transferred to the uterus and the accuracy of PGT-M was confirmed by amniocentesis at 16 weeks of gestation.

Conclusions
Our results suggest that HLRS can be applied for PGT-M of monogenic disorders or de novo mutations where the mutations haplotype cannot be determined due to absence of affected relatives.

Published: August 2020

AbstractNocardia takedensis was first isolated in 2005, from soil in Japan. We report here two cases of lymphangitis in France (2012–2017) caused by N. takedensis both occurring after skin injury while gardening, which enabled its inoculation. The two patients were immunocompromised and successfully treated by an antimicrobial agent active on the isolated strain, trimethoprim-sulfamethoxazole and amoxicillin-clavulanic acid for patient one and patient two, respectively. Our study along with previous ones supports the idea of a newly recognized cutaneous opportunistic pathogen and reinforces the recommendation of using gloves during soil exposure for immunocompromised patients. Lastly, according to data found in the literature, we would recommend trimethoprim-sulfamethoxazole as an efficient empirical antibiotic therapy in case of cutaneous infection caused by N. takedensis.
Oxytocin reduces adipose tissue inflammation in obese mice
Authors: Szeto Angela , Cecati Monia , Ahmed Raisa , McCabe Philip M. , Mendez Armando J. 
Published: August 2020

Abstract
Background
Obesity and adipose tissue expansion is characterized by a chronic state of systemic inflammation that contributes to disease. The neuropeptide, oxytocin, working through its receptor has been shown to attenuate inflammation in sepsis, wound healing, and cardiovascular disease. The current study examined the effects of chronic oxytocin infusions on adipose tissue inflammation in a murine model of obesity, the leptin receptor-deficient (db/db) mouse.

Methods
The effect of obesity on oxytocin receptor protein and mRNA expression in adipose tissue was evaluated by Western blotting and real-time polymerase chain reaction. Mice were implanted with osmotic minipumps filled with oxytocin or vehicle for 8 weeks. At study endpoint adipose tissue inflammation was assessed by measurement of cytokine and adipokine mRNA tissue levels, adipocyte size and macrophage infiltration via histopathology, and plasma levels of adiponectin and serum amyloid A as markers of systemic inflammation.

Results
The expression of adipose tissue oxytocin receptor was increased in obese db/db mice compared to lean controls. In adipose tissue oxytocin infusion reduced adipocyte size, macrophage infiltration, IL-6 and TNFα mRNA expression, and increased the expression of the anti-inflammatory adipokine, adiponectin. In plasma, oxytocin infusion reduced the level of serum amyloid A, a marker of systemic inflammation, and increased circulating adiponectin.

Conclusions
In an animal model of obesity and diabetes chronic oxytocin treatment led to a reduction in visceral adipose tissue inflammation and plasma markers of systemic inflammation, which may play a role in disease progression.
Three-dimensional intracardiac echocardiography and pulmonary embolism
Authors: Yastrebov Konstantin , Brunel Laurencie , Paterson Hugh S. , Williams Zoe A. , Bannon Paul G. 
Published: August 2020

Abstract
Background
Three-dimensional intracardiac echocardiography (3D ICE) with wide azimuthal elevation is a novel technique performed for assessment of cardiac anatomy and guidance of intracardiac procedures, being able to provide unique views with good spatial and temporal resolution. Complications arising from this invasive procedure and the value of 3D ICE in the detection and diagnosis of acute cardiovascular pathology are not comprehensively described. This case illustrates a previously unreported iatrogenic complication of clot displacement from the intra-vascular sheath upon insertion of a 3D ICE catheter and the value of 3D ICE in immediate diagnosis of clot in transit through the heart with pulmonary embolism.

Case presentation
We conducted a translational study of 3D ICE with wide azimuthal elevation to guide implantation of a left ventricular assist device (Impella CP®) in eight adult sheep. A large-bore 14 Fr central venous sheath was used to enable right atrial and right ventricular access for the intracardiac catheter. Insertion of the 3D ICE catheter was accompanied by a sudden severe cardiorespiratory deterioration in one animal. 3D ICE revealed a large highly mobile mass within the right heart chambers, determined to be a clot-in-transit. The diagnosis of pulmonary clot embolism resulting from the retrograde blood entry into the large-bore sheath introducer, rapid clot formation and consequent displacement into venous circulation by the ICE catheter was made. The sheep survived this life-threatening event following institution of cardiovascular support allowing completion of the primary research protocol.

Conclusion
This report serves as a serious warning to the researchers and clinicians utilizing long large-bore sheath introducers for 3D ICE and illustrates the value of 3D ICE in detecting clot-in-transit within right heart chambers.
Impact of delays in radiotherapy of head and neck cancer on outcome
Authors: Žumer Barbara , Pohar Perme Maja , Jereb Simona , Strojan Primož 
Published: August 2020

Abstract
Background
In head and neck cancer (HNC), the relationship between a delay in starting radiotherapy (RT) and the outcome is unclear. The aim of the present study was to determine the impact of the amount of time before treatment intervention (TTI) and the growth kinetics of individual tumors on treatment outcomes and survival.

Methods
Two hundred sixty-two HNC patients with 273 primary tumors, treated with definitive (chemo) RT, were retrospectively analyzed. The TTI was defined as the time interval between the date of histopathologic diagnosis and the first day of the RT course. Volumetric data on 57 tumors were obtained from diagnostic and RT planning computer tomography (CT) scans in order to calculate the tumor growth kinetic parameters.

Results
No significant association between locoregional control or cause-specific hazards and TTI was found. The log hazard for locoregional recurrence linearly increased during the first 40 days of waiting for RT, although this was not significant. The median tumor volume relative increase rate and tumor volume doubling time was 3.2%/day and 19 days, respectively, and neither had any impact on locoregional control or cause-specific hazards.

Conclusion
The association between a delay in starting RT and the outcome is complex and does not harm all patients waiting for RT. Further research into imaging-derived kinetic data on individual tumors is warranted in order to identify patients at an increased risk of adverse outcomes due to a delay in starting RT.
Reconstruction of time-consistent species trees
Authors: Lafond Manuel , Hellmuth Marc 
Published: August 2020

Abstract
Background
The history of gene families—which are equivalent to event-labeled gene trees—can to some extent be reconstructed from empirically estimated evolutionary event-relations containing pairs of orthologous, paralogous or xenologous genes. The question then arises as whether inferred event-labeled gene trees are “biologically feasible” which is the case if one can find a species tree with which the gene tree can be reconciled in a time-consistent way.

Results
In this contribution, we consider event-labeled gene trees that contain speciations, duplications as well as horizontal gene transfer (HGT) and we assume that the species tree is unknown. Although many problems become NP-hard as soon as HGT and time-consistency are involved, we show, in contrast, that the problem of finding a time-consistent species tree for a given event-labeled gene can be solved in polynomial-time. We provide a cubic-time algorithm to decide whether a “time-consistent” species tree for a given event-labeled gene tree exists and, in the affirmative case, to construct the species tree within the same time-complexity.

Authors: Zhao Chen , Luo Lei , Liu Liehua , Li Pei , Liang Lichuan , Gao Yongjian , Luo Fei , Xu Jianzhong , Zhou Qiang 
Published: August 2020

Abstract
Purpose
To compare the efficacy, safety, and technical characteristics of anterior-only and posterior-only approach surgeries for the treatment of consecutive multisegment thoracic and lumbar tuberculosis.

Methods
Thirty-five patients who developed consecutive multisegment thoracic and lumbar tuberculosis from September 2012 to May 2016 were retrospectively analyzed. Group A was the posterior-only surgery group, and group B was the anterior-only surgery group. The data on the surgery, deformity correction, functional scores, and complications were compared between the two groups.

Results
There was no significant difference in the operation time or blood loss between groups A and B (P > 0.05). The preoperative average Cobb angle of kyphosis in groups A and B were 36.2 ± 15.2° and 27.9 ± 7.7°, respectively, which significantly decreased to 4.9 ± 11.8° and 10.4 ± 5.6° after the operation, respectively (P < 0.05). At the final follow-up, the angles were 7.1 ± 10.5° and 14.6 ± 8.0°. The correction angle and correction rate in group A (31.3 ± 16.6°, 88.6 ± 43.6%) were greater than those in group B (17.5 ± 4.4°, 64.9 ± 14.0%) (P < 0.05). There was no significant difference in the loss angle between groups A and B (P > 0.05), but the loss rate in group B (24.0 ± 27.8%) was higher than that in group A (9.6 ± 10.2%) (P < 0.05). There was no significant difference in the incidence of complications between the two groups (P > 0.05).

Conclusion
The posterior-only and anterior-only approaches can lead to satisfactory clinical results in the treatment of patients with consecutive multisegment thoracic and lumbar tuberculosis. With posterior-only surgery, kyphosis can be better corrected, and the correction can be better maintained than with anterior-only surgery.
An evaluation of a mental health literacy course for Arabic speaking religious and community leaders in Australia: effects on posttraumatic stress disorder related knowledge, attitudes and help-seeking
Authors: Slewa-Younan Shameran , Guajardo Maria Gabriela Uribe , Mohammad Yaser , Lim Henry , Martinez Gabriela , Saleh Randa , Sapucci Michele 
Published: August 2020

Abstract
Background
Australia is an ethnically diverse nation with one of the largest refugee resettlement programs worldwide, including high numbers of refugees with an Arabic speaking background. Evidence suggests that refugees can demonstrate high levels of psychological distress and are at a higher risk of developing mental illness such as posttraumatic stress disorder (PTSD) and major depressive disorder (MDD). Notwithstanding, research has also shown Arabic speaking refugees have lower levels of professional help-seeking behaviours, postulated to be related to mental health literacy levels.

Methods
A culturally sensitive mental health literacy (MHL) training program was developed and delivered in Arabic to Arabic speaking religious and community leaders using a 1-day training workshop format. An uncontrolled pre-, and post study design was used to provide a preliminary evaluation of improvement in PTSD-related knowledge, attitudes and help-seeking measures.

Results
A total of 54 adults were trained, with 52 completing the pre- and post-intervention questionnaire. Significant differences were found post-training in measures such as the ability to recognise mental health problems (p = 0.035) and an increased recognition of the role that medication can play in the treatment of PTSD (p = 0.00). Further, an improvement in negative attitudes such as a desire for social distance (p = 0.042) was noted and participants reported more helpful strategies in line with promoting professional help-seeking following training (p = 0.032).

Conclusion
Our findings indicated the training led to an improvement of some measures of MHL. To the best of our knowledge, this is the first time that the MHL program has been tailored for Arabic speaking religious and community leaders; who assist refugees with an Arabic background. By equipping community leaders with the knowledge to better respond to mental health problems, the overall goal of improving the mental health outcomes of Arabic speaking refugee communities is closer to being realised.
Prehospital management of burns requiring specialized burn centre evaluation: a single physician-based emergency medical service experience
Authors: Maudet Ludovic , Pasquier Mathieu , Pantet Olivier , Albrecht Roland , Carron Pierre-Nicolas 
Published: August 2020

Abstract
Background
Emergency medical services regularly encounter severe burns. As standards of care are relatively well-established regarding their hospital management, prehospital care is comparatively poorly defined. The aim of this study was to describe burned patients taken care of by our physician-staffed emergency medical service (PEMS).

Methods
All patients directly transported by our PEMS to our burn centre between January 2008 and December 2017 were retrospectively enrolled. We specifically addressed three “burn-related” variables: prehospital and hospital burn size estimations, type and volume of infusion and pain assessment and management. We divided patients into two groups for comparison: TBSA < 20% and ≥ 20%. We a priori defined clinically acceptable limits of agreement in the small and large burn group to be ±5% and ± 10%, respectively.

Results
We included 86 patients whose median age was 26 years (IQR 12–51). The median prehospital TBSA was 10% (IQR 6–25). The difference between the prehospital and hospital TBSA estimations was outside the limits of agreement at 6.2%. The limits of agreement found in the small and large burn groups were − 5.3, 4.4 and − 10.1, 11, respectively. Crystalloid infusion was reported at a median volume of 0.8 ml/kg/TBSA (IQR 0.3–1.4) during the prehospital phase, which extrapolated over the first 8 h would equal to a median volume of 10.5 ml/kg/TBSA. The median verbal numeric rating scale on scene was 6 (IQR 3–8) and 3 (IQR 2–5) at the hospital (p < 0.001). Systemic analgesia was provided to 61 (71%) patients, predominantly with fentanyl (n = 59; 69%), followed by ketamine (n = 7; 8.1%). The median doses of fentanyl and ketamine were 1.7 mcg/kg (IQR 1–2.6) and 2.1 mg/kg (IQR 0.3–3.2), respectively.

Conclusions
We found good agreement in burn size estimations. The quantity of crystalloid infused was higher than the recommended amount, suggesting a potential risk for fluid overload. Most patients benefited from a correct systemic analgesia. These results emphasized the need for dedicated guidelines and decision support aids for the prehospital management of burned patients.
