Abstract
Background
Discrimination due to gender and ethnicity has been found to be widespread in medicine and healthcare. Swedish and European legislation list seven discrimination grounds (age, sex, ethnicity, religion, sexuality, non-binary gender identity, and disability) which may intersect with each other; yet these have only been sparsely researched. The aim of this study was to assess the extent of discrimination, based on these seven discrimination grounds, amongst final-year medical students in Sweden.

Methods
A web-based survey, based on the CHERRIES-checklist, was disseminated to course coordinators and program directors in charge of final year medical students at all seven medical schools in Sweden. Quantitative data were analyzed using descriptive statistics, Fisher’s exact test, and logistic regression. Free-text answers were analyzed thematically using the “Master Suppression techniques” conceptual framework.

Results
Of the 1298 medical students contacted, 247 (19%) took part in the survey. Almost half (n = 103, 42%) had experienced some form of discrimination, and this difference was statistically significant by gender (p = 0.012), self-perceived ethnicity (p < 0.001), country of birth other than Scandinavia (p < 0.001) and visible religious signs (p = 0.037). The most common type of discrimination was gender-based (in 83% of students who had experienced discrimination), followed by age (48%), and ethnicity (42%). In the logistic regression, women/non-binary gender (p = 0.001, OR 2.44 [95% CI 1.41–4.22]), country of birth not in Scandinavia (p < 0.001, OR 8.05 [2.69–24.03]), non-Caucasian ethnicity (p = 0.04, OR 2.70 [1.39–5.27]), and disability (p = 0.02, OR 13.8 [1.58–12040]) were independently associated with discrimination. Half of those who had experienced religion-based discrimination and nearly one-third of victims of ethnicity-based discrimination reported “large” or “extreme” impact of this. Clinical staff or supervisors were the most common offenders (34%), closely followed by patients and their relatives (30%), with non-Caucasian respondents significantly more likely to experience discrimination by patients (p < 0.001).

Conclusions
Discrimination appears to be frequent in medical school, even in one of the world’s “most equal countries”. Discrimination is most commonly gender- or ethnicity-based, with ethnicity- and religion-based discrimination appearing to have the largest impact. Future research should continue to evaluate discrimination from an intersectional perspective, adapted for local contexts and legislations.

Abstract
Background
Discussing patients with cancer in a multidisciplinary team meeting (MDTM) is customary in cancer care worldwide and requires a significant investment in terms of funding and time. Efficient collaboration and communication between healthcare providers in all the specialisms involved is therefore crucial. However, evidence-based criteria that can guarantee high-quality functioning on the part of MDTMs are lacking. In this systematic review, we examine the factors influencing the MDTMs’ efficiency, functioning and quality, and offer recommendations for improvement.

Methods
Relevant studies were identified by searching Medline, EMBASE, and PsycINFO databases (01–01-1990 to 09–11-2021), using different descriptions of ‘MDTM’ and ‘neoplasm’ as search terms. Inclusion criteria were: quality of MDTM, functioning of MDTM, framework and execution of MDTM, decision-making process, education, patient advocacy, patient involvement and evaluation tools. Full text assessment was performed by two individual authors and checked by a third author.

Results
Seventy-four articles met the inclusion criteria and five themes were identified: 1) MDTM characteristics and logistics, 2) team culture, 3) decision making, 4) education, and 5) evaluation and data collection. The quality of MDTMs improves when the meeting is scheduled, structured, prepared and attended by all core members, guided by a qualified chairperson and supported by an administrator. An appropriate amount of time per case needs to be established and streamlining of cases (i.e. discussing a predefined selection of cases rather than discussing every case) might be a way to achieve this. Patient centeredness contributes to correct diagnosis and decision making. While physicians are cautious about patients participating in their own MDTM, the majority of patients report feeling better informed without experiencing increased anxiety. Attendance at MDTMs results in closer working relationships between physicians and provides some medico-legal protection. To ensure well-functioning MDTMs in the future, junior physicians should play a prominent role in the decision-making process. Several evaluation tools have been developed to assess the functioning of MDTMs.

Conclusions
MDTMs would benefit from a more structured meeting, attendance of core members and especially the attending physician, streamlining of cases and structured evaluation. Patient centeredness, personal competences of MDTM participants and education are not given sufficient attention.

Abstract
Background
Venoms are ecological innovations that have evolved numerous times, on each occasion accompanied by the co-evolution of specialised morphological and behavioural characters for venom production and delivery. The close evolutionary interdependence between these characters is exemplified by animals that control the composition of their secreted venom. This ability depends in part on the production of different toxins in different locations of the venom gland, which was recently documented in venomous snakes. Here, we test the hypothesis that the distinct spatial distributions of toxins in snake venom glands are an adaptation that enables the secretion of venoms with distinct ecological functions.

Results
We show that the main defensive and predatory peptide toxins are produced in distinct regions of the venom glands of the black-necked spitting cobra (Naja nigricollis), but these distributions likely reflect developmental effects. Indeed, we detected no significant differences in venom collected via defensive ‘spitting’ or predatory ‘biting’ events from the same specimens representing multiple lineages of spitting cobra. We also found the same spatial distribution of toxins in a non-spitting cobra and show that heterogeneous toxin distribution is a feature shared with a viper with primarily predatory venom.

Conclusions
Our findings suggest that heterogeneous distributions of toxins are not an adaptation to controlling venom composition in snakes. Instead, it likely reflects physiological constraints on toxin production by the venom glands, opening avenues for future research on the mechanisms of functional differentiation of populations of protein-secreting cells within adaptive contexts.

Abstract
Background
Leishmaniases are a group of anthropo-zoonotic parasitic diseases caused by a protozoan of the Leishmania genus, affecting both humans and other vertebrates, including dogs. L. infantum is responsible for the visceral and occasionally cutaneous form of the disease in humans and canine leishmaniasis. Previously, we have shown that L. infantum induces a mild but significant increase in endoplasmic reticulum (ER) stress expression markers to promote parasites survival in human and murine infected macrophages. Moreover, we demonstrated that the miRNA hsa-miR-346, induced by the UPR-activated transcription factor sXBP1, was significantly upregulated in human macrophages infected with different L. infantum strains. However, the ER stress response in infected dogs, which represent an important reservoir for Leishmania parasite, was described once recently, whereas the miR-346 expression was not reported before. Therefore, this study aimed to investigate these pathways in the canine macrophage-like cell line DH82 infected by Leishmania spp. and to evaluate the presence of cfa-miR-346 in plasma of non-infected and infected dogs.
The DH82 cells were infected with L. infantum and L. braziliensis parasites and the expression of cfa-mir-346 and several ER stress markers was evaluated by quantitative PCR (qPCR) at different time points. Furthermore, the cfa-miR-346 was monitored in plasma collected from non-infected dogs (n = 11) and dogs naturally infected by L. infantum (n = 18).

Results
The results in DH82 cells showed that cfa-mir-346 was induced at both 24 h and 48 h post-infection with all Leishmania strains but not with tunicamycin, accounting for a mechanism of induction independent from sXBP1, unlike what was previously observed in human cell lines. Moreover, the cfa-miR-346 expression analysis on plasma revealed a significant increase in infected dogs compared to non-infected dogs.

Conclusions
Here for the first time, we report the upregulation of cfa-miR-346 induced by Leishmania infection in canine macrophage-like cells and plasma samples of naturally infected dogs. According to our results, the cfa-miR-346 appears to be linked to infection, and understanding its role and identifying its target genes could contribute to elucidate the mechanisms underlying the host–pathogen interaction in leishmaniasis.

Abstract
Background
The anti-coagulation protocol of patients with hemorrhage risk primary disease who need extracorporeal membrane oxygenation (ECMO) supported is controversial. This study evaluated the feasibility of a new anti-coagulation strategy, that is heparin-free after 3000 IU heparin loaded in veno-venous ECMO (VV ECMO) supported acute respiratory failure patients with hemorrhage risk.

Methods
A retrospective study was performed in a series of hemorrhage risk patients supported with VV ECMO at the First Affiliated Hospital of Zhengzhou University, between June 2012 to Sept 2020. A total of 70 patients received a low heparin bolus of 3000 units for cannulation but without subsequent, ongoing heparin administration. Patients were divided into survival (n = 25) and non-survival group (n = 45). Data of coagulation, hemolysis and membrane lung function were calculated and analyzed. The complications of patients were recorded. Finally, the binary Logistic regression was conducted.

Results
The longest heparin-free time was 216 h, and the mean heparin-free time was 102 h. Compared with survivors, the non-survivors were showed higher baseline SOFA score and lower platelet counts in 0.5 h, 24 h, 48 h and 96 h after ECMO applied. However, there was no significant differences between survivors and non-survivors in ACT, APTT, INR, D-dimer, fibrinogen, LDH, blood flow rate, Δp and Ppost-MLO2 (all p < 0.05) of all different time point. Moreover, only the baseline SOFA score was significantly associated with mortality (p < 0.001, OR(95%CI): 2.754 (1.486–5.103)) while the baseline levels of ACT, APTT, INR, platelet, D-dimer, fibrinogen and LDH have no association with mortality. The percentage of thrombosis complications was 54.3% (38/70) including 3 oxygenator changed but there was no significant difference of complications in survival and non-survival groups (p > 0.05).

Conclusions
The anticoagulation protocol that no heparin after a 3000 units heparin bolus in VV ECMO supported acute respiratory failure patients with hemorrhage risk is feasible.

Published: June 2022

Abstract
Background
Understanding the experiences, needs, preferences, and behaviors of people living with HIV (PLHIV) are critical to tailor HIV treatment. However, there is limited empirical evidence in Ethiopia on the views of PLHIV regarding their experiences with current antiretroviral therapy (ART) services and preferred models of HIV treatment. Hence, this study aimed to explore the patients’ experiences of taking medications and preferences for ART service provision in Northwest Ethiopia.

Methods
A phenomenological study design was employed. In this study, stable and 18 years old and above PLHIVs, who had been using ART service at four public hospitals and two health centers in East Gojjam, West Gojjam and Awi zones, and Bahir Dar city administration of Amhara National Regional State, Northwest Ethiopia, were purposively selected. Fifteen in-depth interviews were conducted from July 2021 to September 2021 to collect data. ATLAS.ti version 9 software was used for coding translated transcripts. A thematic analysis approach was employed.

Findings
Participants in this study had reported positive and negative experiences in receiving ART services and also varied preferences toward ART service features. The study identified five themes on experiences for ART service and 15 attributes of ART service characteristics. The identified themes were stigma, time, availability of drugs and providers, costs for clinic visits, and provider-patient interaction. The fifteen attributes were buddy system, ART refill (individualized or group), ART packaging and labeling, drug formulation and administration, ART room labeling, distance, location of service, preferences on involvement in treatment decision-making, the person providing ART refills, provider’s attitude, spatial arrangement of ART room, time of health facility operation, time spent at clinics, and total cost of the visit.

Conclusions
The results raise awareness for the positive and negative experiences of patients informing us about barriers and supporting factors in ART service provision. They open up the potential for HIV treatment service improvement. The preferences of PLHIVs toward ART service delivery features were heterogeneous. Policy and program efforts should tailor ART services that suit patients’ needs and priorities in Ethiopia. Future research should further assess the reasons for patients’ distrust of the community ART delivery models.

Abstract
Background
Spinal cord injury leading to paraplegia affects the mobility and physiological well-being of one in a thousand people. Powered exoskeletons can temporarily restore the ability to walk. Their relevance in daily life is still limited because of low performance beyond ground that is even. CYBATHLON is an international competition promoting improvements in assistive technology. In this article, we present the latest design and results of testing of TWIICE One version 2018, one of the competing devices in the 2020 race.

Methods
A person with a motor-complete spinal cord injury at thoracic level T10 participated as race pilot. Training ahead of the race took place over one week at a rate of 2 h per day. The time to perform each of the seven tasks of the competition was recorded together with the number of repetitions. Performance is compared over the training period and against the 2016 race results.

Results
Progression was observed in all tasks and accounted for by both user training and technology improvements. Final competition rank was second out of seven participating teams, with a record time of 4′40". This represents an average improvement of 40% with respect to comparable obstacles of the 2016 race, explaining the two ranks of improvement since then.

Conclusion
These results help understand which features had a positive impact on the real-life performance of the device. Understanding how design affects performance is key information to create devices that really improve the life of people living with paraplegia.

Published: June 2022

Abstract
Background
Wearable devices have been found effective in training ankle control in patients with neurological diseases. However, the neural mechanisms associated with using wearable devices for ankle training remain largely unexplored. This study aimed to investigate the ankle tracking performance and brain white matter changes associated with ankle tracking learning using a wearable-device system and the behavior–brain structure relationships in middle-aged and older adults.

Methods
Twenty-six middle-aged and older adults (48–75 years) participated in this study. Participants underwent 5-day ankle tracking learning with their non-dominant foot using a custom-built ankle tracking system equipped with a wearable sensor and a sensor-computer interface for real-time visual feedback and data acquisition. Repeated and random sequences of target tracking trajectories were both used for learning and testing. Ankle tracking performance, calculated as the root-mean-squared-error (RMSE) between the target and actual ankle trajectories, and brain diffusion spectrum MR images were acquired at baseline and retention tests. The general fractional anisotropy (GFA) values of eight brain white matter tracts of interest were calculated to indicate their integrity. Two-way (Sex × Time) mixed repeated measures ANOVA procedures were used to investigate Sex and Time effects on RMSE and GFA. Correlations between changes in RMSE and those in GFA were analyzed, controlling for age and sex.

Results
After learning, both male and female participants reduced the RMSE of tracking repeated and random sequences (both p < 0.001). Among the eight fiber tracts, the right superior longitudinal fasciculus II (R SLF II) was the only one which showed both increased GFA (p = 0.039) after learning and predictive power of reductions in RMSE for random sequence tracking with its changes in GFA [β = 0.514, R2 change = 0.259, p = 0.008].

Conclusions
Our findings implied that interactive tracking movement learning using wearable sensors may place high demands on the attention, sensory feedback integration, and sensorimotor transformation functions of the brain. Therefore, the SLF II, which is known to perform these brain functions, showed corresponding neural plasticity after such learning, and its plasticity also predicted the behavioral gains. The SLF II appears to be a very important anatomical neural correlate involved in such learning paradigms.

Abstract
Background
Hypertension is a major risk factor of cardiovascular mortality. Mood disorders represent a growing public health problem worldwide. A complex relationship is present between mood disorders and cardiovascular diseases. However, less data is available about the level of depression and anxiety in different hypertension phenotypes. The aim of our study was to evaluate psychometric parameters in healthy controls (Cont), in patients with white-coat hypertension (WhHT), with chronic, non-resistant hypertension (non-ResHT), and with chronic, treatment-resistant hypertension (ResHT).

Methods
In a cross-sectional study setup 363 patients were included with the following distribution: 82 Cont, 44 WhHT, 200 non-ResHT and 37 ResHT. The patients completed the Beck Depression Inventory (BDI) and the Hamilton Anxiety Scale (HAM-A).

Results
BDI points were higher in WhHT (7 (3–11)) and ResHT (6 (3–11.5)) compared with Cont (3 (1–6), p < 0.05). Similarly, HAM-A points were higher in WhHT (8 (5–15)) and ResHT (10.5 (5.25–18.75)) compared with Cont (4 (1–7), p < 0.05) and also compared with non-ResHT (5 (2–10), p < 0.05). ResHT was independently associated with HAM-A scale equal or above 3 points (Beta = 3.804, 95%CI 1.204–12.015). WhHT was independently associated with HAM-A scale equal or above 2 points (Beta = 7.701, 95%CI 1.165–18.973) and BDI scale equal or above 5 points (Beta = 2.888, 95%CI 1.170–7.126).

Conclusions
Our results suggest psychopathological similarities between white-coat hypertension and resistant hypertension. As recently it was demonstrated that white-coat hypertension is not a benign condition, our findings can have relevance for future interventional purposes to improve the outcome of these patients.
