ObjectiveTo evaluate the influence of intracerebral haemorrhage (ICH) location on stroke outcomes.MethodsWe included patients recruited to a UK hospital-based, multicentre observational study of adults with imaging confirmed spontaneous ICH. The outcomes of interest were occurrence of a cerebral ischaemic event (either stroke or transient ischaemic attack) or a further ICH following study entry. Haematoma location was classified as lobar or non-lobar.ResultsAll 1094 patients recruited to the CROMIS-2 (Clinical Relevance of Microbleeds in Stroke) ICH study were included (mean age 73.3 years; 57.4% male). There were 45 recurrent ICH events (absolute event rate (AER) 1.88 per 100 patient-years); 35 in patients presenting with lobar ICH (n=447, AER 3.77 per 100 patient-years); and 9 in patients presenting with non-lobar ICH (n=580, AER 0.69 per 100 patient-years). Multivariable Cox regression found that lobar ICH was associated with ICH recurrence (HR 8.96, 95% CI 3.36 to 23.87, p<0.0001); similar results were found in multivariable completing risk analyses. There were 70 cerebral ischaemic events (AER 2.93 per 100 patient-years); 29 in patients presenting with lobar ICH (AER 3.12 per 100 patient-years); and 39 in patients with non-lobar ICH (AER 2.97 per 100 patient-years). Multivariable Cox regression found no association with ICH location (HR 1.13, 95% CI 0.66 to 1.92, p=0.659). Similar results were seen in completing risk analyses.ConclusionsIn ICH survivors, lobar ICH location was associated with a higher risk of recurrent ICH events than non-lobar ICH; ICH location did not influence risk of subsequent ischaemic events.Trial registration numberNCT02513316.
Heterogeneous Island Models and Their Application to Recommender Systems and Electric Vehicle Charging
Authors: Balcar Štěpán , Pilát Martin 
Published: June 2020

In this paper we describe a general framework for parallel optimization based on the island model of evolutionary algorithms. The framework runs a number of optimization methods in parallel with periodic communication. In this way, it essentially creates a parallel ensemble of optimization methods. At the same time, the system contains a planner that decides which of the available optimization methods should be used to solve the given optimization problem and changes the distribution of such methods during the run of the optimization. Thus, the system effectively solves the problem of online parallel portfolio selection. The proposed system is evaluated in a number of common benchmarks with various problem encodings as well as in two real-life problems — the optimization in recommender systems and the training of neural networks for the control of electric vehicle charging.

Published: June 2020

Background: Adequate research is not reported so far to underline the influence of commonly used polycentric knee joints on gait performance of subjects with trans-femoral amputation. Objective: The intent of this investigation is to analyze prosthetic gait of unilateral traumatic trans-femoral amputees with polycentric four-bar linkage knee and compare it with normal subjects for evaluating any asymmetry in gait performance. Methods: Objective three-dimensional gait analysis of 15 subjects [mean (age): 36.4 (10.7) years] were performed in gait lab through force plate and optoelectronic devices to measure temporal-spatial parameters, kinematic and kinetic performances. Gait patterns of amputees were compared with those of 15 individuals with normal gait to analyze distinct functionalities of existing polycentric knee. Results: Asymmetry in gait was observed between amputees and normal subjects for all variables concerned ([Formula: see text]). Amputee gait was with significantly lesser velocity, cadence with shorter step and stride length. There was significantly less hip, knee and pelvic motions, however, pelvic obliquity and rotation did not show significant difference from the normal subjects. The vertical component of the ground reaction force differed significantly between prosthetic and intact limb [49.7 (8.5)% and 90.4 (7.4)% body weight] and also from normal subjects [107.5 (2.4)% body weight] during stance ([Formula: see text]). Interpretation and Conclusion: This difference may be attributed to nonproportionate loading of limbs and mechanical adaptations for counteracting deficiencies of prosthetic side. This study will help to explain gait asymmetry in trans-femoral amputees and to identify underlying mechanisms to enhance the quality of the existing design of prosthetic knee through optimizing design parameters and utilizing appropriate materials.

Abstract

gBRCA1/2 mutations increase the incidence of breast cancer by interrupting the homologous recombination repair (HRR) pathway. Although gBRCA1 and gBRCA2 breast cancer have similar clinical profiles, different molecular characteristics have been observed. In this study, we conducted comprehensive genomic analyses and compared gBRCA1/2 breast cancer. Sanger sequencing to identify gBRCA1/2 mutations was conducted in 2,720 patients, and gBRCA1 (n = 128) and gBRCA2 (n = 126) mutations were analyzed. Within this population, deep target sequencing and matched whole-transcriptome sequencing (WTS) results were available for 46 and 34 patients, respectively. An internal database of patients with breast cancer with wild-type gBRCA was used to compile a target sequencing (n = 195) and WTS (n = 137) reference dataset. Three specific mutation sites, p.Y130X (n = 14) and p.1210Afs (n = 13) in gBRCA1 and p.R294X (n = 22) in gBRCA2, were comparably frequent. IHC subtyping determined that the incidence of triple-negative breast cancer was higher among those with a gBRCA1 mutation (71.9%), and estrogen receptor–positive breast cancer was dominant in those with a gBRCA2 mutation (76.2%). gBRCA1/2 mutations were mutually exclusive with PIK3CA somatic mutations (P &lt; 0.05), and gBRCA1 frequently cooccurred with TP53 somatic mutations (P &lt; 0.05). The median tumor mutation burden was 6.53 per megabase (MB) in gBRCA1 and 6.44 per MB in gBRCA2. The expression of AR, ESR1, and PGR was significantly upregulated with gBRCA2 mutation compared with gBRCA1 mutation. gBRCA1 and gBRCA2 breast cancer have similar clinical characteristics, but they have different molecular subtypes, coaltered somatic mutations, and gene expression patterns.

Implications:
Even though gBRCA1 and gBRCA2 mutations both alter HRR pathways, our results suggest that they generate different molecular characteristics and different mechanisms of carcinogenesis.
Mechanical Thrombectomy in Basilar Artery Occlusion
Authors: Kwak Hyo Sung , Park Jung Soo 
Published: June 2020

Background and Purpose:
Basilar artery occlusion (BAO) is associated with a high risk of disability and mortality. The objective of this study was to investigate prognostic factors in patients with acute basilar artery occlusion treated with mechanical thrombectomy, focusing on collateral status and recanalization time from symptom onset.

Methods:
Eligible patients from January 2012 to October 2019 who underwent endovascular treatment due to acute BAO were reviewed. The baseline posterior circulation collateral status was assessed with the basilar artery on computed tomography angiography score and posterior circulation collateral score. Good outcomes were defined as a modified Rankin Scale score of ≤2 at 3 months and successful recanalization as Thrombolysis in Cerebral Infarction grades 2b, 3. The associations between baseline and clinical parameters and favorable outcomes were evaluated with logistic regression.

Results:

Our sample included a total of 81 eligible patients (49 males, mean age 70.3 years) with a median baseline and discharge National Institutes of Health Stroke Scale score of 12. Patients with good outcomes showed a lower baseline National Institutes of Health Stroke Scale score, a greater proportion of distal BAO, and a higher basilar artery on computed tomography angiography and posterior circulation collateral score (
P
<0.001). According to subgroup analysis of patients within and over 6 or 12 hours, the time from symptom onset to recanalization was not correlated with good outcomes. Multivariable logistic analysis showed baseline National Institutes of Health Stroke Scale <15 (odds ratio, 8.49 [95% CI, 2.01–35.82];
P
=0.004), posterior circulation collateral score ≥6 (odds ratio, 3.79 [95% CI, 1.05–13.66];
P
=0.042), and distal BAO (odds ratio, 3.67 [95% CI, 1.10–12.26];
P
=0.035) were independent predictors of good outcomes.

Conclusions:
This study suggested that good collateral circulation and distal BAO are independent predictors of clinical outcome after endovascular treatment in patients with acute BAO. In particular, patients with good initial collateral status and distal BAO may consider endovascular treatment even if the treatment is started beyond the standard time limits.
Predicting Longitudinal Progression in Functional Mobility After Stroke
Authors: Buvarp Dongni , Rafsten Lena , Sunnerhagen Katharina S. 
Published: June 2020

Background and Purpose:
A majority of people with stroke remain impaired in their functional mobility. The aim of the study was to determine longitudinal changes in functional mobility after stroke.

Methods:
The study was of a longitudinal and prospective design. The functional mobility was assessed using the Timed Up-and-Go test on 5 different occasions: 5 days after onset, within 24 hours after discharge, 1 month after discharge, 3 months, and 1 year poststroke. Stroke severity was stratified based on impairments and activity limitations using a baseline cluster analysis. A multilevel model was developed to predict longitudinal progression in functional mobility based on stroke severity.

Results:

One-hundred-thirty-five patients were included at baseline. Two distinct subgroups (moderate stroke [52%] and mild stroke [48%]) were identified based on impairments and activity limitations using clustering. Ninety-one patients were included in the longitudinal analysis. After controlling for age and cognition, significant improvements in functional mobility were found in the moderate stroke group between baseline and 1 year poststroke (mean difference in Timed Up-and-Go test time, –6.4 s, adjusted
P
<0.001). Patients with moderate stroke had a maximum rate of improvement in functional mobility during the first 3 months poststroke and then declined significantly at 1 year (12% increase in Timed Up-and-Go test time, adjusted
P
=0.025). Younger patients had better functional mobility. Although there was also a slight improvement in the mild stroke group, it was not statistically significant.

Conclusions:
The recovery of functional mobility differs between mild and moderate stroke. Patients with moderate stroke improved their functional mobility during the first 3 months, after which it decreased significantly. These findings suggest that long-term rehabilitation is desirable to maintain and perhaps increase the gained functional mobility. Older patients and those with moderate impairments and activity limitations have particular needs.

Gallstone-Induced Inflammatory Fibrosis: A Relentless Clinical Course of Retained Gallstones after Laparoscopic Cholecystectomy
Authors: Heestand Gregory , Morrison Bryant , Correa Adrian , Palmer Suzanne , Mateo Rod , Hagen Jeffrey , Genyk Yuri , Selby Rick , Sher Linda 
Published: June 2020

Multiple reports in the literature confirm that retained gallstones spilled during laparoscopic cholecystectomy perpetuate chronic inflammation and suppuration long after the initial operation. Two patients who had previously undergone laparoscopic cholecystectomy presented to our institution with complications of retained stones. Patient 1 presented with right upper quadrant pain and a mass involving the right hepatic lobe. Patient 2 presented with a draining right flank abscess. Both underwent exploratory laparotomy at which time multiple abscess cavities were found, many of which contained retained gallstones. Patient 1 required reoperation for recurrent abscesses 7 months after the initial procedure and has been disease free for 6 months. Patient 2 had abscess recurrence that required percutaneous drainage 1 year after the original procedure and has not had recurrence for 4 years. This paper was presented at the 6thWorld Congress of the International Hepato Pancreato Biliary Association, June 5, 2004, Washington, DC.

Published: June 2020

The impact of venous thromboembolism (VTE) after hepatectomy on patient morbidity, mortality, and resource usage remains poorly defined. Better understanding of thromboembolic complications is needed to improve perioperative management and overall outcomes. About 3973 patients underwent hepatectomy within NSQIP between 2005 and 2008. Patient characteristics, operative features, and postoperative correlates of VTE were compared with identify risk factors for VTE and to assess its overall impact on postoperative outcomes. Overall incidence of postoperative VTE was 2.4 per cent. Risk factors for postoperative VTE included older age, male gender, compromised functional status, degree of intraoperative blood transfusion, preoperative albumin level (all P < 0.05), and extent of hepatectomy ( P = 0.004). Importantly, major postoperative complications, including acute renal failure, pneumonia, sepsis, septic shock, reintubation, prolonged ventilation, cardiac arrest, and reoperation were all associated with higher rates of VTE (all P < 0.05). Operative mortality was increased among patients with VTE (6.5% vs 2.4%, P = 0.03), and patients with VTE had a 2-fold increase in hospital length of stay (12.0 vs 6.0 days, P < 0.001). Postoperative VTE remains a significant source of morbidity, mortality, and increased resource usage after hepatectomy in the United States. Routine aggressive VTE prophylaxis measures are imperative to avoid development of VTE among patients requiring hepatectomy.

Published: June 2020

Objectives: Borderline personality disorder is a complex mental disorder that is associated with a high degree of suffering for the individual. Dialectical behaviour therapy has been studied in the largest number of controlled trials for treatment of individuals with borderline personality disorder. The conversational model is a psychodynamic treatment also developed specifically for treatment of borderline personality disorder. We report on the outcomes of a randomised trial comparing dialectical behaviour therapy and conversational model for treatment of borderline personality disorder in a routine clinical setting. Method: Participants had a diagnosis of borderline personality disorder and a minimum of three suicidal and/or non-suicidal self-injurious episodes in the previous 12 months. Consenting individuals were randomised to either dialectical behaviour therapy or conversational model and contracted for 14 months of treatment ( n = 162 commenced therapy). Dialectical behaviour therapy involved participants attending weekly individual therapy, weekly group skills training and having access to after-hours phone coaching. Conversational model involved twice weekly individual therapy. Assessments occurred at baseline, mid-treatment (7 months) and post-treatment (14 months). Assessments were conducted by a research assistant blind to treatment condition. Primary outcomes were change in suicidal and non-suicidal self-injurious episodes and severity of depression. We hypothesised that dialectical behaviour therapy would be more effective in reducing suicidal and non-suicidal self-injurious behaviour and that conversational model would be more effective in reducing depression. Results: Both treatments showed significant improvement over time across the 14 months duration of therapy in suicidal and non-suicidal self-injury and depression scores. There were no significant differences between treatment models in reduction of suicidal and non-suicidal self-injury. However, dialectical behaviour therapy was associated with significantly greater reductions in depression scores compared to conversational model. Conclusion: This research adds to the accumulating body of knowledge of psychotherapeutic treatment of borderline personality disorder and supports the use of both dialectical behaviour therapy and conversational model as effective treatments in routine clinical settings, with some additional benefits for dialectical behaviour therapy for persons with co-morbid depression.

Published: June 2020

Objective: To determine the impact of an exercise-based prehabilitation (EBPrehab) program on pre- and postoperative exercise capacity, functional capacity (FC) and quality of life (QoL) in patients awaiting elective coronary artery bypass graft surgery (CABG). Design: A two-group randomized controlled trail. Setting: Ambulatory prehabilitation. Subjects: Overall 230 preoperative elective CABG-surgery patients were randomly assigned to an intervention (IG, n = 88; n = 27 withdrew after randomization) or control group (CG, n = 115). Intervention: IG: two-week EBPrehab including supervised aerobic exercise. CG: usual care. Main measures: At baseline (T1), one day before surgery (T2), at the beginning (T3) and at the end of cardiac rehabilitation (T4) the following measurements were performed: cardiopulmonary exercise test, six-minute walk test (6MWT), Timed-Up-and-Go Test (TUG) and QoL (MacNew questionnaire). Results: A total of 171 patients (IG, n = 81; CG, n = 90) completed the study. During EBPrehab no complications occurred. Preoperatively FC (6MWTIG: 443.0 ± 80.1 m to 493.5 ± 75.5 m, P = 0.003; TUGIG: 6.9 ± 2.0 s to 6.1 ± 1.8 s, P = 0.018) and QoL (IG: 5.1 ± 0.9 to 5.4 ± 0.9, P < 0.001) improved signiﬁcantly more in IG compared to CG. Similar effects were observed postoperatively in FC (6MWDIG: Δ-64.7 m, pT1–T3 = 0.013; Δ+47.2 m, pT1–T4 < 0.001; TUGIG: Δ+1.4 s, pT1–T3 = 0.003). Conclusions: A short-term EBPrehab is effective to improve perioperative FC and preoperative QoL in patients with stable coronary artery disease awaiting CABG-surgery.

Published: June 2020

Background Sparse evidence has detailed the clinical phenotype of migraine presenting as isolated facial pain. Objective and methods: This was a prospective audit, part of our multidisciplinary facial pain service evaluation, aiming to phenotype patients with migraine presenting as isolated facial pain who attended our service between 2013 and 2018. Results Fifty-eight patients were diagnosed with migraine with isolated facial pain (F = 46, 79.3%; mean age: 49.0 years, ± 9.85). Sixty-six percent of patients met the criteria for episodic migraine. The pain was strictly unilateral in 79% and located over the maxillary region in 85% of patients. Associated cranial autonomic signs/symptoms were reported by 45% of our cohort. A percentage of 77% of patients was triptan responders. Conclusions Migraine presenting as isolated facial pain is a rare but treatable condition with some distinct demographic and clinical characteristics. It is a diagnosis of exclusion that should be evaluated in specialised multidisciplinary facial pain clinics.

Published: June 2020

Objective To explore the factors associated with attendance and attendance pattern in BreastScreen Norway. Methods We evaluated the number of invitations (n = 1,253,995) and attendances, 2015–2019, stratified by age, invitation method, screening unit and time of appointment. Attendance pattern was analysed for women invited 10 times (n = 47,979), 1996–2019. The association of education level, body mass index, physical activity and smoking status with attendance was analysed for a sub-sample of women (n = 37,930). Descriptive statistics were used to analyse attendance, and negative binomial regression was used to analyse the association between the total number of attendances and education level and lifestyle factors. Results The attendance rate was 76.0%, 2015–2019. The rate was 78.0% for women aged >64 and 73.9% for those <55 . We found a rate of 82.0% for women who received a digital invitation, while it was 73.7% for those invited by post. The rate was 78.1% for invitations in the late afternoon, 3–6 p.m., while later appointments reached a rate of 73.7%. Half of the women invited 10 times attended all times. The predicted total number of attendances was 9 out of 10 for the factors investigated. Conclusion The highest attendance rates were shown for women aged >64, those who received digital invitations and those having appointments in late afternoon. The differences in predicted number of attendances between the investigated factors were minor. Overall, BreastScreen Norway has a high attendance rate. However, efforts aimed at increasing the attendance in specific groups should be considered.
