Abstract
Background
Freezing of gait (FOG) is a common and debilitating gait impairment in Parkinson’s disease. Further insight into this phenomenon is hampered by the difficulty to objectively assess FOG. To meet this clinical need, this paper proposes an automated motion-capture-based FOG assessment method driven by a novel deep neural network.

Methods
Automated FOG assessment can be formulated as an action segmentation problem, where temporal models are tasked to recognize and temporally localize the FOG segments in untrimmed motion capture trials. This paper takes a closer look at the performance of state-of-the-art action segmentation models when tasked to automatically assess FOG. Furthermore, a novel deep neural network architecture is proposed that aims to better capture the spatial and temporal dependencies than the state-of-the-art baselines. The proposed network, termed multi-stage spatial-temporal graph convolutional network (MS-GCN), combines the spatial-temporal graph convolutional network (ST-GCN) and the multi-stage temporal convolutional network (MS-TCN). The ST-GCN captures the hierarchical spatial-temporal motion among the joints inherent to motion capture, while the multi-stage component reduces over-segmentation errors by refining the predictions over multiple stages. The proposed model was validated on a dataset of fourteen freezers, fourteen non-freezers, and fourteen healthy control subjects.

Results
The experiments indicate that the proposed model outperforms four state-of-the-art baselines. Moreover, FOG outcomes derived from MS-GCN predictions had an excellent (r = 0.93 [0.87, 0.97]) and moderately strong (r = 0.75 [0.55, 0.87]) linear relationship with FOG outcomes derived from manual annotations.

Conclusions
The proposed MS-GCN may provide an automated and objective alternative to labor-intensive clinician-based FOG assessment. Future work is now possible that aims to assess the generalization of MS-GCN to a larger and more varied verification cohort.

Abstract
Background
Adiposity and mitochondrial dysfunction are related factors contributing to metabolic disease development. This pilot study examined whether in vivo and ex vivo indices of mitochondrial metabolism were differentially associated with body composition in males and females.

Methods
Thirty-four participants including 19 females (mean 27 yr) and 15 males (mean 29 yr) had body composition assessed by dual energy x-ray absorptiometry and magnetic resonance (MR) imaging. Monocyte reserve capacity and maximal oxygen consumption rate (OCR) were determined ex vivo using extracellular flux analysis. In vivo quadriceps mitochondrial function was measured using 31P-MR spectroscopy based on post-exercise recovery kinetics (τPCr). The homeostatic model assessment of insulin resistance (HOMA-IR) was calculated from fasting glucose and insulin levels. Variables were log-transformed, and Pearson correlations and partial correlations were used for analyses.

Results
Mitochondrial metabolism was similar between sexes (p > 0.05). In males only, higher fat mass percent (FM%) was correlated with lower reserve capacity (r = − 0.73; p = 0.002) and reduced muscle mitochondrial function (r = 0.58, p = 0.02). Thigh subcutaneous adipose tissue was inversely related to reserve capacity in males (r = − 0.75, p = 0.001), but in females was correlated to higher maximal OCR (r = 0.48, p = 0.046), independent of FM. In females, lean mass was related to greater reserve capacity (r = 0.47, p = 0.04). In all participants, insulin (r = 0.35; p = 0.04) and HOMA-IR (r = 0.34; p = 0.05) were associated with a higher τPCr.

Conclusions
These novel findings demonstrate distinct sex-dependent associations between monocyte and skeletal muscle mitochondrial metabolism with body composition. With further study, increased understanding of these relationships may inform sex-specific interventions to improve mitochondrial function and metabolic health.
“Using information to shape perception”: tobacco industry documents study of the evolution of Corporate Affairs in the Miller Brewing Company
Authors: McCambridge Jim , Garry Jack , Kypri Kypros , Hastings Gerard 
Published: May 2022

AbstractBackgroundThe Miller Brewing Company (MBC) was wholly owned by Phillip Morris (PM), between 1970 and 2002. Tobacco industry document studies identify alliances between the alcohol and tobacco industries to counter U.S. policies in the 1980s and 1990s. This investigation sought to study in-depth inter-relationships between MBC and PM, with a particular focus on alcohol policy issues. We used the Truth Tobacco Industry Documents library to trace the evolution of corporate affairs and related alcohol policy orientated functions within and between MBC and PM.ResultsMBC was structured and led by PM senior executives from soon after takeover in 1970. Corporate Affairs sought to influence public perceptions of alcohol to align them with business interests. Alcohol education was specifically designed to prevent the adoption of policies inimical to those interests (e.g., raising excise taxes). Strategic consideration of alcohol policy issues was integrated within company-wide thinking, which sought to apply lessons from tobacco to alcohol and vice versa. PM directly led key alcohol industry organisations nationally and globally, which have successfully delayed the adoption and implementation of known effective policy measures in the U.S. and worldwide.ConclusionsPM has been a key architect of alcohol industry political strategies. This study builds on earlier work on alcohol companies in the tobacco documents, and offers historical data on how tobacco companies have used commercial involvements in other sectors to influence wider public health policy. We are only beginning to appreciate how multi-sectoral companies internally develop political strategies across product categories. Global health and national governmental policy-making needs to be better protected from business interests that fundamentally conflict with public health goals.

Abstract
Background
Due to respiratory motion, accurate radiotherapy delivery to thoracic and abdominal tumors is challenging. We aimed to quantify the ability of mechanical ventilation to reduce respiratory motion, by measuring diaphragm motion magnitudes in the same volunteers during free breathing (FB), mechanically regularized breathing (RB) at 22 breaths per minute (brpm), variation in mean diaphragm position across multiple deep inspiration breath-holds (DIBH) and diaphragm drift during single prolonged breath-holds (PBH) in two MRI sessions.

Methods
In two sessions, MRIs were acquired from fifteen healthy volunteers who were trained to be mechanically ventilated non-invasively We measured diaphragm motion amplitudes during FB and RB, the inter-quartile range (IQR) of the variation in average diaphragm position from one measurement over five consecutive DIBHs, and diaphragm cranial drift velocities during single PBHs from inhalation (PIBH) and exhalation (PEBH) breath-holds.

Results
RB significantly reduced the respiratory motion amplitude by 39%, from median (range) 20.9 (10.6–41.9) mm during FB to 12.8 (6.2–23.8) mm. The median IQR for variation in average diaphragm position over multiple DIBHs was 4.2 (1.0–23.6) mm. During single PIBHs with a median duration of 7.1 (2.0–11.1) minutes, the median diaphragm cranial drift velocity was 3.0 (0.4–6.5) mm/minute. For PEBH, the median duration was 5.8 (1.8–10.2) minutes with 4.4 (1.8–15.1) mm/minute diaphragm drift velocity.

Conclusions
Regularized breathing at a frequency of 22 brpm resulted in significantly smaller diaphragm motion amplitudes compared to free breathing. This would enable smaller treatment volumes in radiotherapy. Furthermore, prolonged breath-holding from inhalation and exhalation with median durations of six to seven minutes are feasible.

The effect of corticosteroid injection in the treatment of greater trochanter pain syndrome: a systematic review and meta-analysis of randomized controlled trials
Authors: Wang Yule , Wang Kaijin , Qin Yiling , Wang Sanrong , Tan Botao , Jia Lang , Jia Gongwei , Niu Lingchuan 
Published: May 2022

Abstract
Background
corticosteroid injection (CSI) has been used to treat greater trochanter pain syndrome (GTPS) for many years. However, so far, the efficacy of CSI in the treatment of GTPS is still controversial. Therefore, the aim of this review is to evaluate the effectiveness of CSI in comparison with sham intervention, nature history, usual care, platelet-rich plasma (PRP), physiotherapy/exercise therapy, dry needling, or other nonsurgical treatment for improvements in pain and function in GTPS.

Methods
PubMed (Medline), Embase, Cochrane Library were searched from their inception until April 2021. Randomized controlled trails (RCTs) comparing CSI to nonsurgical treatment were included. Data on the effect of CSI on pain and function were extracted and checked by two review authors independently. The treatment effect was analyzed in the short term, medium term, and long term.

Results
Eight RCTs (764 patients) were included. This review suggests CSI may be superior to usual care and ‘wait and see,’ ESWT, but may not be superior to exercise, PRP, dry needling, and sham intervention in short-term pain or function improvement. In terms of medium-term pain or function improvement, CSI may be superior to usual care and ‘wait and see,’ but may not be superior to PRP. In terms of long-term pain or function improvement, CSI may be inferior to PRP and ESWT, but it may be superior to usual care and ‘wait and see’ at 12 months.

Conclusions
Due to the small sample size and lack of sufficient clinical studies, current evidence is equivocal regarding the efficacy of CSI in the treatment of GTPS. Considering the limitations, more large-sample and high-quality RCTs are needed to prove the therapeutic effect of CSI on GTPS.

Impact of gender differences on hemostasis in patients after coronary artery bypass grafts surgeries in the context of tranexamic acid administration
Authors: Wang Enshi , Wang Yang , Hu Shengshou , Yuan Su 
Published: May 2022

Abstract
Background
Sex differences present in the blood management of patients after coronary artery bypass grafts (CABG) surgeries. Tranexamic acid (TXA) performed well in maintaining hemostasis during and after surgeries. However, the impact of sex differences on blood control after CABG in patients who received TXA was not investigated.

Methods
Overall, 29,536 patients undergoing CABG with TXA administration from 2009 to 2019 in our hospital were included. Propensity score matching was performed. Finally, 6808 males and 6808 females were matched based on 23 covariates.

Results
Female patients had a 0.36-fold lower incidence of reoperations due to major hemorrhage or cardiac tamponade compared to males (1.3% vs. 2.0%, p = 0.001, OR = 0.64, 95%CI = 0.49–0.84). Females had a median of 100 ml less blood loss in 24 h (median 360 vs. 460 ml, p < 0.0001), 150 ml less in 48 h (median 580 vs. 730 ml, p < 0.0001), and 180 ml less in total (median 760 vs. 940 ml, p < 0.0001) than male patients. The red blood cell (RBC) transfusion rate in female was 1.53-fold higher than that in male (33.0% vs. 21.6%, OR = 1.53, 95% CI = 1.43–1.63, p < 0.0001). Females also had higher morbidities than males after CABGs.

Conclusions
Females had less blood loss than males after CABG with the TXA treatment. Females still had a higher RBC transfusion rate after surgery. Morbidities in women were also higher than that in men.

Authors: Miki Takahiro , Kondo Yu , Kurakata Hiroshi , Buzasi Eva , Takebayashi Tsuneo , Takasaki Hiroshi 
Published: May 2022

Abstract
Background
To apply the Bio-Psych-Social (BPS) model into clinical practice, it is important not to focus on psychosocial domains only since biomedical factors can also contribute to chronic pain conditions. The cognitive functional therapy (CFT) is the management system based on the BPS model for chronic nonspecific low back pain (CNSLBP).

Objectives
This study aimed to compare CFT with the other interventions for CNSLBP regarding pain, disability/functional status, QoL and psychological factors.

Design
This study was a systematic review and meta-analysis of a randomised controlled trial.

Method
Literature Search was conducted in electronic search engines. Enrolled participants included 1) CNSLBP and 2) primary, secondary, or tertiary care patients. CFT was the interventions included. Comparisons were any types of treatment.

Results
Three studies met the eligibility criteria. The total number of participants was 336. For pain intensity, MD [95% CIs] was -1.38 [-2.78 − 0.02] and -1.01 [-1.92 − -0.10] at intermediate and long term for two studies, respectively. About disability/functional status, SMD [95% CIs] was -0.76 [-1.46 − -0.07] at the intermediate for three studies and MD [95% CIs] was -8.48 [-11.47 − -5.49] at long term for two studies. About fear of physical activity, MD [95% CIs] was -3.01 [-5.14 − -0.88] and -3.56 [-6.43 − -0.68] at intermediate and long term for two studies, respectively. No studies reported scores associated with QOL. All the quality of the evidence was very low.

Conclusions
Three studies were included and the quality of all the evidence was very low. Although the study found statistically significant differences in some measures, the effectiveness of the CFT will need to be re-evaluated in the future.

Abstract
Background
Caregivers and family members of Intensive Care Unit (ICU) survivors can face emotional problems following patient discharge from hospital. We aimed to evaluate the impact of a multi-centre integrated health and social care intervention, on caregiver and family member outcomes.

Methods
This study evaluated the impact of the Intensive Care Syndrome: Promoting Independence and Return to Employment (InS:PIRE) programme across 9 sites in Scotland. InS:PIRE is an integrated health and social care intervention. We compared caregivers who attended this programme with a contemporary control group of ICU caregivers (usual care cohort), who did not attend.

Results
The primary outcome was anxiety measured via the Hospital Anxiety and Depression Scale at 12 months post-hospital discharge. Secondary outcome measures included depression, carer strain and clinical insomnia. A total of 170 caregivers had data available at 12 months for inclusion in this study; 81 caregivers attended the InS:PIRE intervention and completed outcome measures at 12 months post-hospital discharge. In the usual care cohort of caregivers, 89 completed measures. The two cohorts had similar baseline demographics. After adjustment, those caregivers who attended InS:PIRE demonstrated a significant improvement in symptoms of anxiety (OR: 0.42, 95% CI: 0.20–0.89, p = 0.02), carer strain (OR: 0.39; 95% CI: 0.16–0.98 p = 0.04) and clinical insomnia (OR: 0.40; 95% CI: 0.17–0.77 p < 0.001). There was no significant difference in symptoms of depression at 12 months.

Conclusions
This multicentre evaluation has shown that caregivers who attended an integrated health and social care intervention reported improved emotional health and less symptoms of insomnia, 12 months after the delivery of the intervention.
Interspecific hybridization in tomato influences endogenous viral sRNAs and alters gene expression
Authors: Lopez-Gomollon Sara , Müller Sebastian Y. , Baulcombe David C. 
Published: May 2022

AbstractBackgroundHybridization is associated with the activation of transposable elements and changes in the patterns of gene expression leading to phenotypic changes. However, the underlying mechanisms are not well understood.ResultsHere, we describe the changes to the gene expression in interspecificSolanumhybrids that are associated with small RNAs derived from endogenous (para)retroviruses (EPRV). There were prominent changes to sRNA profiles in these hybrids involving 22-nt species produced in the DCL2 biogenesis pathway, and the hybridization-induced changes to the gene expression were similar to those in adcl2mutant.ConclusionsThese findings indicate that hybridization leads to activation of EPRV, perturbation of small RNA profiles, and, consequently, changes in the gene expression. Such hybridization-induced variation in the gene expression could increase the natural phenotypic variation in natural evolution or in breeding for agriculture.
Effectiveness of multimodal exercises integrated with cognitive-behavioral therapy in working patients with chronic neck pain: protocol of a randomized controlled trial with 1-year follow-up
Authors: Monticone M. , Simone Vullo S. , Lecca L. I. , Meloni F. , Portoghese I. , Campagna M. 
Published: May 2022

Abstract
Background
The etiology of neck pain is multifactorial and includes personal and work-related factors such as age, sex, wrong postures, and repeated strains. Studies based on bio-psychosocial model also link chronic neck pain to psychological factors. Over time, the use of multidisciplinary interventions for chronic neck pain has grown in order to improve disability, pain, and adaptive cognitions and behaviors towards patients’ problems. The objective is to evaluate the effectiveness of an individual-based multidisciplinary rehabilitation program that integrates cognitive-behavioral therapy focused on kinesiophobia with specific exercises in the treatment of patients with chronic neck pain, employed in different working activities.

Methods
A randomized, parallel-group superiority-controlled trial will be conducted with 1-year follow-up. One hundred seventy patients engaged in several working activities (blue collar and white collar workers) will be randomly allocated to either the experimental (receiving a multidisciplinary rehabilitation program combining multimodal exercises with psychologist-lead cognitive-behavioral therapy sessions) or the control group (receiving general care physiotherapy). Both groups will follow individual-based programs once a week for 10 weeks. The main outcome measures will be the Neck Disability Index, the Tampa Scale for Kinesiophobia, the Pain Catastrophizing Scale, a pain numerical rating scale, the Short-Form Health Survey, and the Work Ability Index. Participants will be evaluated before, after training, and after 12 months.

Discussion
Findings may provide empirical evidence on the effectiveness of an individual-based multidisciplinary rehabilitation program on inducing clinically significant and long-term improvements in the disability, pain, psychological factors, and quality of life of workers with chronic neck pain and that these would be maintained in the long term. Hence, this trial might contribute towards refining guidelines for good clinical practice and might be used as a basis for health authorities’ recommendations.

Self-guided digital treatment with virtual reality for panic disorder and agoraphobia: a study protocol for a randomized controlled trial
Authors: Planert Jari , Machulska Alla , Hildebrand Anne-Sophie , Roesmann Kati , Otto Esra , Klucken Tim 
Published: May 2022

Abstract
Background
Cognitive behavioral therapy is the first-line treatment for patients with panic disorder (PD) and agoraphobia (AG). Yet, many patients remain untreated due to limited treatment resources. Digital self-guided short-term treatment applications may help to overcome this issue. While some therapeutic applications are already supported by health insurance companies, data on their efficacy is limited. The current study investigates the effect of self-guided digital treatment comprising psychoeducation and virtual reality exposure therapy (VRET).

Methods
Thirty patients diagnosed with PD, AG, or panic disorder with agoraphobia (PDA) will be randomly assigned to either the experimental group (EG) or the control group (CG). Participants of both groups will undergo baseline diagnostics in the first two sessions. The subsequent treatment for the EG consists of a self-guided 6-week phase of application-based psychoeducation, one therapy session preparing for the VRET, and 4 weeks of application-based self-guided VRET. To control for the potential effects of the therapy session with the therapist, the CG will receive relaxation and stress-reduction training instead. All patients will then undergo a closing session which terminates with the post-assessment (~ 10 weeks after baseline assessment) and a follow-up assessment 6 weeks following the closing session. Symptom severity (primary outcome) will be assessed at baseline, interim, post-treatment, and follow-up. Additionally, remission status (secondary outcome) will be obtained at follow-up. Both measures will be compared between the groups.

Discussion
The current study aims at providing insights into the efficacy of short-term treatment applications including psychoeducation and self-guided VRET. If successful, this approach might be a feasible and promising way to ease the burden of PD, AG, and PDA on the public health system and contribute to a faster access to treatment.
