Abstract
Background
The beach chair position that is commonly used in shoulder surgery is associated with relative hypovolemia, which leads to a reduction in arterial blood pressure. The effects of patient positioning on the accuracy of non-invasive continuous blood pressure monitoring with the ClearSight™ system (CS-BP; Edwards Lifesciences, Irvine CA, USA) have not been studied extensively. Our research aim was to assess agreement levels between CS-BP measurements with traditional blood pressure monitoring techniques.

Methods
For this prospective self-controlled study, we included 20 consecutively treated adult patients undergoing elective shoulder surgery in the beach chair position. We performed Bland-Altman analyses to determine agreement levels between blood pressure values from CS-BP and standard non-invasive (NIBP) methods. Perioperative measurements were done in both the supine (as reference) and beach chair surgical positions. Additionally, we compared invasive blood pressure (IBP) measurements with both the non-invasive methods (CS-BP and NIBP) in a sub-group of patients (n = 10) who required arterial blood pressure monitoring.

Results
We analyzed 229 data points (116 supine, 113 beach chair) from the entire cohort; per patient measurements were based on surgical length (range 3–9 supine, 2–10 beach chair). The mean difference (±SD; 95% limits of agreement) in the mean arterial pressure (MAP) between CS-BP and NIBP was − 0.9 (±11.0; − 24.0–22.2) in the beach chair position and − 4.9 mmHg (±11.8; − 28.0–18.2) when supine. In the sub-group, the difference between CS-BP and IBP in the beach chair position was − 1.6 mmHg (±16.0; − 32.9–29.7) and − 2.8 mmHg (±15.3; − 32.8–27.1) in the supine position. Between NIBP and IBP, we detected a difference of 3.0 mmHg (±9.1; − 20.8–14.7) in the beach chair position, and 4.6 mmHg (±13.3; − 21.4–30.6) in the supine position.

Conclusions
We found clinically acceptable mean differences in MAP measurements between the ClearSight™ and non-invasive oscillometric blood pressure systems when patients were in either the supine or beach chair position. For all comparisons of the monitoring systems and surgical positions, the standard deviations and limits of agreement were wide.

Published: October 2020

Abstract
Background
Self-rated health (SRH) focuses on the patient’s own perception, and represents an important patient-reported outcome. The aim was to investigate SRH one to 5 years after stroke, follow the development over time and search for factors associated with SRH.

Methods
Consecutive stroke patients admitted to Stroke Units at the Skaraborg Hospital, Sweden were included 2007–2009 (n = 2190). Patient-reported outcomes were collected annually over 5 years using a postal questionnaire. SRH was assessed by the question about general health from SF-36. Factors associated with SRH were investigated by multiple logistic regression analysis.

Results
Response-rate was > 90% at all time points. Overall, 40.2, 41.9, 40.7, 45.0 and 46.3% of the patients reported good SRH, 1 to 5 years after stroke. Performance in activities of daily living (ADL) was strongly associated with good SRH; 49.8 and 14.7% after 1 year in independent and dependent survivors respectively, p < 0.001. In independent survivors 1 year after stroke, good SRH was positively associated with female sex (OR = 2.0; p = < 0,001), physical activity (OR = 2.14; p = < 0,001), car driving (OR = 2.25; p = < 0,001), and negatively associated with age (OR = 0.99; p = < 0,001), pain (OR = 0.49; p = < 0,001), depression (OR = 0.30; p = < 0,001), and self-perceived unmet care needs (OR = 0.39; p = < 0,001). In dependent survivors, depression (OR = 0.23; p = < 0,001) and age (OR = 0.96; p = < 0,05), were negatively associated with good SRH 1 year after stroke. Similar patterns were observed throughout the follow-up.

Conclusion
The proportion stroke survivors reporting their health as good is slightly increasing over time. After stroke, SRH is associated with pain, depression, ability to perform activities and self-perceived unmet care needs, indicating that efforts to support stroke survivors in the chronic phase after stroke should concentrate on targeting these factors.

Abstract
Background
Valproate (VPA) is a commonly prescribed antiepileptic drug for patients experiencing epileptic seizures due to brain tumors. VPA increases radiation sensitivity in various tumor cells in vitro due to complex mechanisms. This could make tumors more vulnerable to ionizing radiation or overcome radioresistance. Yet, clinical data on possible improvement of tumor control by adding VPA to tumor therapy is controversial. Potentially radiosensitizing effects of VPA on healthy tissue remain unclear. To determine individual radiosensitivity, we analyzed blood samples of individuals taking VPA.

Methods
Ex vivo irradiated blood samples of 31 adult individuals with epilepsy were studied using 3-color fluorescence in situ hybridization. Aberrations in chromosomes 1, 2 and 4 were analyzed. Radiosensitivity was determined by the mean breaks per metaphase (B/M) and compared to age-matched (2:1) healthy donors.

Results
The patient cohort (n = 31; female: 38.7%) showed an increase of their average B/M value compared to healthy individuals (n = 61; female: 56.9%; B/M: 0.480 ± 0.09 vs. 0.415 ± 0.07; p = .001). The portion of radiosensitive (B/M >  0.500) and distinctly radiosensitive individuals (B/M >  0.600) was increased in the VPA group (54.9% vs. 11.3 and 9.7% vs. 0.0%; p < .001). In 3/31 patients, radiosensitivity was determined prior to and after VPA treatment and radiosensitivity was increased by VPA-treatment.

Conclusions
In our study, we confirmed that patients treated with VPA had an increased radiosensitivity compared to the control group. This could be considered in patients taking VPA prior to the beginning of radiotherapy to avoid toxic side effects of VPA-treatment.

Published: October 2020

Abstract
Background
Concepts such as participation and environment may differ across cultures. Consequently, to use a measure like the Participation and Environment Measure for Children and Youth (PEM-CY) in other than the original English-speaking contexts, cultural adaptation needs to be assured. The aim of this study was to cross-culturally translate and adapt the PEM-CY into German as it is used in Germany, Austria and Switzerland.

Methods
Fifteen parents of children and adolescents with disabilities from three German speaking countries participated in three rounds of think-aloud interviews. We followed the procedure of cultural equivalence guidelines including two additional steps. Data was analyzed by content analysis using semantic, idiomatic, experiential and conceptual equivalence.

Results
Results show adaptations mainly focused on experiential and conceptual equivalence, with conceptual equivalence being the most challenging to reach. Examples of experiential equivalence included adapting the examples of activities in the PEM-CY to reflect those typical in German speaking countries. Conceptual equivalence mainly addressed aspects of “involvement” and “environment” of children and adolescents and was reached through adaptations such as enhanced instructions and structures, and additional definitions.

Conclusions
This study presents a cross-cultural translation and adaptation process to develop a German version of the PEM-CY that is suitable for Germany, Austria and Switzerland. Using a modified cultural adaptation process, a culturally adapted version of PEM-CY (German) is now available for research, practice and further validation.

AbstractBackgroundThe main goal of pediatric palliative care (PPC) is to improve or maintain the best possible quality of life (QoL) for the child and their family. PPC can be provided in community health centres, within the specialist health care service and/or in the child’s home. Home is often the preferred place for families, and recommendations state that, whenever possible, the family home should be the centre of care for the child. The aim of this study is to systematically review the experiences and needs of families with children receiving palliative care at home.MethodsWe conducted a systematic review and searched the peer-reviewed databases CINAHL, Embase, PsycInfo and MEDLINE for articles published between January 2000 and October 2019. We included 23 studies emphasising the experience of family members when their child (0–18 years) received palliative care at home. We used a thematic analysis to identify relevant themes in the literature, and synthesised the findings from the different studies.ResultsThe review represents the experiences of the families of almost 300 children with life-limiting (LL) and life-threatening (LT) conditions receiving palliative care at home. In general, the children’s mothers are interviewed, and seldom the sick children themselves or their siblings. Most families preferred staying at home since it made it easier to maintain a normal family life, was less stressful for the sick child, and meant that siblings could still attend school and be with friends. Families experienced a range of challenges due to the coordination of care, including a lack of support and adequately skilled staff with appropriate experience. Respite care was needed in order to cope with everyday life. Some studies were not specific concerning the place of care, and some relevant papers may have been omitted.ConclusionsFamilies receiving PPC need organised, individualised support from a skilled PPC team. Respite care is necessary in order to manage a demanding home-care situation and parents need support for siblings. Privacy to be a family is a need, and many families need financial support. Future studies should focus on PPC at home in the perspectives of sick children and their siblings.
SUMO proteins in the cardiovascular system: friend or foe?
Authors: Shetty Prithviraj Manohar Vijaya , Rangrez Ashraf Yusuf , Frey Norbert 
Published: October 2020

AbstractPost-translational modifications (PTMs) are crucial for the adaptation of various signalling pathways to ensure cellular homeostasis and proper adaptation to stress. PTM is a covalent addition of a small chemical functional group such as a phosphate group (phosphorylation), methyl group (methylation), or acetyl group (acetylation); lipids like hydrophobic isoprene polymers (isoprenylation); sugars such as a glycosyl group (glycosylation); or even small peptides such as ubiquitin (ubiquitination), SUMO (SUMOylation), NEDD8 (neddylation), etc. SUMO modification changes the function and/or fate of the protein especially under stress conditions, and the consequences of this conjugation can be appreciated from development to diverse disease processes. The impact of SUMOylation in disease has not been monotonous, rather SUMO is found playing a role on both sides of the coin either facilitating or impeding disease progression. Several recent studies have implicated SUMO proteins as key regulators in various cardiovascular disorders. The focus of this review is thus to summarize the current knowledge on the role of the SUMO family in the pathophysiology of cardiovascular diseases.

AbstractBackgroundResearch from high income countries indicates that suicide is a major mental health care concern and a leading cause of preventable deaths among children and adolescents. Proper assessment and management of youth suicidality is crucial in suicide prevention, but little is known about its prevalence and associated risk factors in Sub-Saharan Africa. In low income countries there is an increased risk of suicide among persons with HIV/AIDS even in the presence of the highly active antiretroviral therapy.ObjectiveTo determine the prevalence of and risk factors for youth suicidality among perinatally infected youth living with HIV/AIDS in Uganda.MethodsWe studied 392 HIV positive children (5–11 years) and adolescents (12–17 years) and their caregivers in Kampala and Masaka districts. Caregivers were administered the suicide assessment section of the MINI International Psychiatric Interview. Socio-demographic characteristics, psychiatric diagnoses, and psychosocial and clinical factors were assessed and suicidality (suicidal ideation and or suicidal attempt) was the outcome variable. Logistic regression was used to calculate odds ratios adjusting for study site and sex at 95% confidence intervals.ResultsCaregivers reported a suicidality rate of 10.7% (CI 8–14.1) in the past one month with higher rates among urban female (12.4%, CI 8.6–17.7) than male (8.7%, CI 5.4–13.8) youth. Lifetime prevalence of attempted suicide was 2.3% (n = 9, CI 1.2–4.4) with the highest rates among urban female youth. Among children, caregivers reported a lifetime prevalence of attempted suicide of 1.5%. The self-reported rate of attempted suicide in the past month was 1.8% (n = 7, CI 0.8–3.7) with lifetime prevalence of 2.8% (n = 11, CI 1.6–5.0). The most common methods used during suicide attempts were cutting, taking overdose of HIV medications, use of organophosphates, hanging, stabbing and self-starvation. Clinical correlates of suicidality were low socioeconomic status (OR = 2.27, CI 1.06–4.87, p = 0.04), HIV felt stigma (OR = 2.10, CI 1.04–3.00, p = 0.02), and major depressive disorder (OR = 1.80, CI 0.48–2.10, p = 0.04). Attention-deficit/hyperactivity disorder was protective against suicidality (OR = 0.41, CI 0.18–0.92, p = 0.04).ConclusionThe one-month prevalence of suicidality among CA-HIV was 10.7%.

AbstractObjectiveThis study aimed to explore the effects of activating GABAB1 receptor by baclofen on proliferation, migration, invasion and epithelial-mesenchymal transition (EMT) of ovarian cancer cells.ResultsOne hundred μmol/L, 200 μmol/L and 300 μmol/L were selected as low, medium and high baclofen concentrations respectively. Cells were divided into four groups: Control, 100 μmol/L, 200 μmol/L and 300 μmol/L. Compared with the control group, the viability, colony formation, migration and invasion of SKOV3 cells were inhibited, and the apoptosis of SKOV3 cells were enhanced significantly at 200 μmol/L and 300 μmol/L baclofen. Moreover, they changed significantly with the increase of baclofen concentration. Compared with the control group, the expression of E-cadherin and GABAB1 increased and the N-cadherin expression decreased significantly in 200 μmol/L and 300 μmol/L groups. Higher concentration of baclofen induced higher expression of E-cadherin and lower expression of N-cadherin.ConclusionBaclofen inhibited the proliferation, cloning, migration, invasion and EMT of ovarian cancer cells by activating GABAB1 receptor. These results might contribute a lot to clarify the role and possible mechanism of GABAB1 receptor in ovarian cancer.

Abstract
Background
Methamphetamine use and harms are rising rapidly. Management of patients with methamphetamine use disorder (MUD) and problematic methamphetamine use (PMU) is challenging, with no clearly established best approach; both psychosocial and pharmacologic interventions have been described. Furthermore, given the diversity of individuals that use methamphetamines, there is a need to assess evidence for treatments for subgroups including youths; gay, bisexual, and other men who have sex with men; individuals with mental health comorbidities; and individuals in correction services. Establishing awareness of the messages regarding treatment from recent clinical practice guidelines (CPG) in the field is also of value.
The first study objective will be to establish a greater understanding of the methods, populations, and findings of controlled studies for psychosocial and pharmacologic treatments for MUD and PMU. Investigation of this information can help establish the potential for advanced syntheses of the evidence (such as network meta-analysis) to compare therapies for this condition and to identify gaps related to key populations where more primary research is needed. Summarizing the recommendations regarding treatment of MUD/PMU from recent CPGs and systematic reviews will be an important secondary objective.

Methods
A scoping review will be performed. Using the OVID platform, MEDLINE, Embase, PsycINFO, and relevant Cochrane databases from EBM Reviews will be searched (from databases’ inception onwards). Eligibility criteria will include individuals described as having MUD or PMU, with designs of interest including randomized trials, non-randomized trials, and controlled cohort studies with three or more months of follow-up; systematic reviews and CPGs will also be sought. Two reviewers (with support from automation tools) will independently screen all citations, full-text articles, and chart data. Different approaches to handling and summarizing the data will be implemented for each type of study design. Tables and graphics will be used to map evidence sources and identify evidence gaps.

Discussion
This research will enhance awareness of evidence addressing the effects of psychosocial and pharmacologic interventions for MUD/PMU overall and in sub-populations, both in terms of recent CPGs/reviews and primary studies; inspection of the latter will also help establish the feasibility of future syntheses to compare treatments, such as network meta-analysis.

Abstract
Introduction
Strong evidence is lacking to support effectiveness of currently implemented tuberculosis infection prevention control (TB-IPC) measures for preventing nosocomial tuberculosis (TB) transmission. This 13-year analysis is the longest follow-up investigation to date to identify risk factors underlying nosocomial TB transmission.

Methods
We monitored all staff of Beijing Chest Hospital each year from 2006 to 2018. Age, gender, duration, department, education, income, respirator, ultraviolet, and ventilation were chosen as variables. Univariate cox regression, correlation analysis, and multivariate cox regression were analyzed sequentially.

Results
Using multivariable cox regression analysis, variables of income, ultraviolet germicidal irradiation (UVGI), natural ventilation and mechanical ventilation conferred significant protective effects, with odds ratios of 0.499, 0.058, 0.003, and 0.015, respectively (P < 0.05). Medical N95 respirator conferred an excellent protective effect, with an associated TB infection rate of 0%. Notably, inadequately maintained mechanical ventilation systems were less protective than natural ventilation systems.

Conclusion
UVGI, adequate ventilation, and use of medical N95 respirator may be risk factors of nosocomial TB transmission.

Published: October 2020

Abstract
Background
Currently, the occurrence of left atrial thrombus despite the provision of heparinization within a few days of hospitalization without atrial fibrillation (AF) and mitral stenosis (MS) is rarely reported.

Case presentation
A 71-year-old woman presented with chest discomfort and dyspnea. Examination revealed ST elevation with sinus rhythm, congestive heart failure, and moderate mitral regurgitation (MR) by transthoracic echocardiography (TTE). Diuretics, a coronary vasodilator, and unfractionated heparin (15,000 units/day) were administered. Four days after hospitalization, her C-reactive protein level had increased; therefore, TTE was repeated, revealing a thrombus in the left atrial appendage, which was probably affected by heparin resistance because of low antithrombin (49%). On day 5, the patient underwent emergency removal of the thrombus, mitral valve replacement, and coronary artery bypass.

Conclusion
Patients can exhibit low left ventricular contractility, even sinus rhythm without MS. Thus, TTE and subsequent coagulation tests including antithrombin must be performed to prevent thrombus.
