Abstract
Prior studies reported the global structure of brain networks exhibits the “small-world” and “rich-world” attributes. However, the underlying structural and functional architecture highlighted by these graph theory findings hasn’t been explicitly related to the morphology of the cortex. This could be attributed to the lower resolution of used folding patterns, such as gyro-sulcal patterns. By defining a novel gyral folding pattern, termed gyral hinge (GH), which is the conjunction of ordinary gyri from multiple directions, we found GHs possess the highest length and cost in the white matter fiber connective network, and the shortest paths in the network tend to travel through GHs in their middle part. Based on these findings, we would hypothesize GHs could reside in the centers of a network core, thereby accounting for the highest cost and the highest communication capacity in a corticocortical network. The following results further support our hypothesis: 1) GHs possess stronger functional network integration capacity. 2) Higher cost is found on the connection with GHs to hinges and GHs to GHs. 3) Moving GHs introduces higher extra network cost. Our findings and hypotheses could reveal a profound relationship among the cortical folding patterns, axonal wiring architectures, and brain functions.

Abstract
The brain’s “default mode network” (DMN) enables flexible switching between internally and externally focused cognition. Precisely how this modulation occurs is not well understood, although it may involve key subcortical mechanisms, including hypothesized influences from the basal forebrain (BF) and mediodorsal thalamus (MD). Here, we used ultra-high field (7 T) functional magnetic resonance imaging to examine the involvement of the BF and MD across states of task-induced DMN activity modulation. Specifically, we mapped DMN activity suppression (“deactivation”) when participants transitioned between rest and externally focused task performance, as well as DMN activity engagement (“activation”) when task performance was internally (i.e., self) focused. Consistent with recent rodent studies, the BF showed overall activity suppression with DMN cortical regions when comparing the rest to external task conditions. Further analyses, including dynamic causal modeling, confirmed that the BF drove changes in DMN cortical activity during these rest-to-task transitions. The MD, by comparison, was specifically engaged during internally focused cognition and demonstrated a broad excitatory influence on DMN cortical activation. These results provide the first direct evidence in humans of distinct BF and thalamic circuit influences on the control of DMN function and suggest novel mechanistic avenues for ongoing translational research.

ABSTRACT

Background
The prevalence and incidence of hyperkalaemia, a potassium abnormality that can potentially have life-threatening consequences, are unclear.

Methods
The objective was to provide the most comprehensive overview of the epidemiology of hyperkalaemia to date within the general population, across different continents, in different healthcare settings and within pre-specified subgroups. Embase and MEDLINE were searched from database inception to 2 February 2021 using the Ovid SP platform. Relevant congress proceedings from 2018 to 2020 were also reviewed for inclusion. There was no language constraint applied. Observational studies from any time period and language reporting prevalence or incidence of hyperkalaemia within both adult and paediatric populations. Four investigators independently screened abstracts and assessed study quality of those meeting the pre-determined inclusion/exclusion criteria. Data extraction was conducted by the lead author with oversight from the senior author and data were pooled using a random-effects model. The measures assessed were the prevalence and incidence of hyperkalaemia. Prevalence was reported as a percentage, whilst incidence was reported as the rate per 100 person years.

Results
In total, 542 articles were included from an initial search of 14 112 articles. Across all adult studies, we report a prevalence of hyperkalaemia (by any definition/threshold) of 6.3% [95% confidence interval (CI): 5.8–6.8%], with an incidence of hyperkalaemia in the adult population of 2.8 (2.3–3.3) cases per 100 person years. Prevalence within the general population was 1.3% (1.0–1.8%), whilst incidence was 0.4 (0.2–0.8) cases per 100 person years. There was a variation by sex with a prevalence of 6.3% (4.9–8.0%) in males and 5.1% (4.0–6.6%) in females. Prevalence also varied according to the definition/threshold of hyperkalaemia used: &gt;5 mmol/L—8.0% (7.2–8.9), ≥5.5 mmol/L—5.9% (3.5–10.0) and ≥6.0 mmol/L—1.0% (0.8–1.4); hyperkalaemia (by any definition/threshold) was highest amongst patients with end-stage kidney disease (21.5%; 18.3–25.3), kidney transplant patients (21.8%; 16.1–29.5) and patients with acute kidney injury (24.3%; 19.3–30.7).

Conclusions
This novel review provides a comprehensive and valuable resource on the prevalence and incidence of hyperkalaemia to better inform clinicians, healthcare providers and health policy makers on the burden of hyperkalaemia across different healthcare settings, patient populations and continents.
Evaluation of the implementation of the Framework Convention on Tobacco Control (FCTC) in Colombia
Authors: Guzman-Tordecilla Deivis Nicolas , Llorente Blanca , Vecino-Ortiz Andres I 
Published: November 2021

AbstractEvidence-based interventions recommended in the Framework Convention on Tobacco Control of the World Health Organization (WHO FCTC) are subject to implementation factors that might affect their actual effectiveness. The Colombian law enacting key commitments from WHO’s FCTC was signed in 2009. This study aims at evaluating the potential impact of the enactment and implementation of these WHO FCTC on four outcomes for tobacco consumption (last-year cigarette smoking prevalence, prevalence of heavy smokers, prevalence of lower-intensity smokers and monthly smoking incidence). We used data from the National Psychoactive Substances Consumption Survey (NPSCS) in 2008 (n = 29 164) and 2013 (n = 32 605), and assessed changes in these four outcomes WHO FCTC using propensity score matching (PSM). Propensity scores were obtained using key socio-demographic variables and by matching through a ‘Kernel’ estimation. Matching quality tests were performed. The common support for both survey samples was 60 793. Sub-analyses were conducted using a governance index to assess the effect of heterogeneous governance levels, proxying implementation, over the country. We found that cigarette year-prevalence and cigarette month-incidence decreased after matching around 8 and 1.2 percentage points between 2008 and 2013, respectively. Consumption might have shifted, at least partially, from heavy smoking towards lower-intensity smoking. Departments with a higher governance index showed larger reductions of tobacco use, possibly associated to a stronger WHO FCTC implementation. This study highlights the impact that the WHO FCTC had on tobacco consumption in a middle-income country and shows the importance of governance strength as a mediating mechanism for WHO FCTC impact. These results advance current knowledge on the effectiveness of WHO FCTC and shed light on the relevance of governance as a key factor in the WHO FCTC implementation.

Published: November 2021

Abstract

Background
A gastrointestinal stromal tumor rupture entails a high risk of recurrence even after curative surgery. However, the definition of rupture is unclear, and the question of whether patients with a minor rupture should be treated with adjuvant imatinib remains controversial.

Methods
The present, retrospective, multicentric study enrolled 57 patients with gastrointestinal stromal tumor with a minor/major tumor rupture, of whom 46 were finally found to be eligible for analysis. Tumor ruptures were subclassified by their degree, timing and cause. Multivariate analysis was performed to identify the risk factors of all types of recurrence as well as of peritoneal recurrence only.

Results
The study cohort included minor (n = 24), intraoperative (n = 19) and iatrogenic (n = 20) ruptures besides the typical types (major, preoperative and spontaneous). All intraoperative ruptures were iatrogenic. In total, 27 patients (58.7%) had a recurrence in the peritoneum (n = 17) and/or the liver (n = 13) during a median follow-up period of 5.8 years, but no recurrence was observed in patients with tumor rupture as a single, high-risk factor. Multivariate analysis found the timing of tumor rupture to be an independent risk factor of poor recurrence-free survival (hazard ratio: 2.37; 95% confidence interval: 1.02–5.49; P = 0.045).

Conclusions
Preoperative tumor rupture in patients with a ruptured gastrointestinal stromal tumor was associated with poor recurrence-free survival. Our results suggested that a distinction should be made between preoperative and intraoperative tumor ruptures when considering the indications for adjuvant imatinib therapy for gastrointestinal stromal tumor patients with tumor rupture as a single, high-risk factor of recurrence.
Cockayne syndrome group B protein regulates fork restart, fork progression and MRE11-dependent fork degradation in BRCA1/2-deficient cells

Published: November 2021

AbstractCockayne syndrome group B (CSB) protein has been implicated in the repair of a variety of DNA lesions that induce replication stress. However, little is known about its role at stalled replication forks. Here, we report that CSB is recruited to stalled forks in a manner dependent upon its T1031 phosphorylation by CDK. While dispensable for MRE11 association with stalled forks in wild-type cells, CSB is required for further accumulation of MRE11 at stalled forks in BRCA1/2-deficient cells. CSB promotes MRE11-mediated fork degradation in BRCA1/2-deficient cells. CSB possesses an intrinsic ATP-dependent fork reversal activity in vitro, which is activated upon removal of its N-terminal region that is known to autoinhibit CSB’s ATPase domain. CSB functions similarly to fork reversal factors SMARCAL1, ZRANB3 and HLTF to regulate slowdown in fork progression upon exposure to replication stress, indicative of a role of CSB in fork reversal in vivo. Furthermore, CSB not only acts epistatically with MRE11 to facilitate fork restart but also promotes RAD52-mediated break-induced replication repair of double-strand breaks arising from cleavage of stalled forks by MUS81 in BRCA1/2-deficient cells. Loss of CSB exacerbates chemosensitivity in BRCA1/2-deficient cells, underscoring an important role of CSB in the treatment of cancer lacking functional BRCA1/2.
Brexit and labour market inequalities: potential spatial and occupational impacts
Authors: Davenport Alexander , Levell Peter 
Published: November 2021

Abstract
In this paper we examine the possible distributional impacts of new trade barriers associated with the new Trade and Cooperation Agreement governing relations between the UK and EU after Brexit. We use a model of labour demand that incorporates input–output links across industries, and that allows for demand substitution by firms and consumers and worker reallocation across industries. We find that workers’ exposure is moderately increasing across the earnings distribution. Exposure is greater for men than for women as they are more likely to work in manufacturing industries that are relatively harder hit by new trade barriers. Looking across areas, we find that exposure to new Brexit trade barriers is uncorrelated with measures of local deprivation and the impacts of the recent Covid-19 pandemic.
Heat adaptation of phage T7 under an extended genetic code
Authors: Cole Austin W , Tran Steven D , Ellington Andrew D 
Published: November 2021

Abstract
While bacteriophages have previously been used as a model system to understand thermal adaptation, most adapted genomes observed to date contain very few modifications and cover a limited temperature range. Here, we set out to investigate genome adaptation to thermal stress by adapting six populations of T7 bacteriophage virions to increasingly stringent heat challenges. Further, we provided three of the phage populations’ access to a new genetic code in which Amber codons could be read as selenocysteine, potentially allowing the formation of more stable selenide-containing bonds. Phage virions responded to the thermal challenges with a greater than 10°C increase in heat tolerance and fixed highly reproducible patterns of non-synonymous substitutions and genome deletions. Most fixed mutations mapped to either the tail complex or to the three internal virion proteins that form a pore across the E. coli cell membrane during DNA injection. However, few global changes in Amber codon usage were observed, with only one natural Amber codon being lost. These results reinforce a model in which adaptation to thermal stress proceeds via the cumulative fixation of a small set of highly adaptive substitutions and that adaptation to new genetic codes proceeds only slowly, even with the possibility of potential phenotypic advantages.
Stress predicts depression symptoms for women living with bipolar disorder during the menopause transition
Authors: Perich Tania , Ussher Jane 
Published: November 2021

Abstract

Objective:
Although sleep disturbance is an important feature in bipolar disorder, the relationship between mood symptoms, sleep disturbances, and hot flash symptom severity during menopause for women with bipolar disorder is largely unknown.

Methods:
Women with bipolar disorder (n = 100) who were categorized as perimenopausal using the STRAW and Monash criteria took part in an international online survey. The survey contained questions on history of reproductive health; the clinical course of bipolar disorder; menopausal symptoms (Menopause Rating Scale [MRS]); depression, anxiety, and stress (Depression Anxiety and Stress Scale—21) and the Altman Mania Rating Scale.

Results:
MRS sleep problems and hot flash severity were positively correlated with each other and with depression, anxiety, and stress symptoms. Mania scores were not significantly correlated with sleep or hot flash severity scores. A stepwise regression analysis on depression symptoms, using MRS sleep disturbance and MRS hot flash severity scores as predictors with anxiety and stress symptoms in the model, found that stress alone predicted 40% of the variance in total depression scores.

Conclusion:
Stress plays an important role in the experience of depression for women living with bipolar disorder during the perimenopausal phase. More research is needed to determine if stress management programs may be helpful for women living with bipolar disorder during this time of life and if these in turn, may improve depressive symptoms.
Denervation of the Joints of the Hand and Wrist: Surgical Techniques and a Systematic Review with Meta-Analysis
Authors: Tieman Thomas E. , Duraku Liron S. , van der Oest Mark J. W. , Hundepool Caroline A. , Selles Ruud W. , Zuidam J. Michiel 
Published: November 2021

Background:
Joint denervation of the wrist, basal joint of the thumb, and the finger is an option for patients with chronic pain. Compared with other surgical treatment options, function is preserved and the rehabilitation time is limited. A systematic review and meta-analysis were performed for each joint to determine whether the choice of technique and choice of denervation of specific articular sensory branches lead to a different outcome.

Methods:
Embase, MEDLINE (OvidSP), Web of Science, Scopus, PubMed publisher, Cochrane, and Google Scholar database searches yielded 17 studies with reported outcome on denervation of the wrist, eight on the basal joint of the thumb, and five on finger joints.

Results:
Overall, the level of evidence was low; only two studies included a control group, and none was randomized. Meta-analysis for pain showed a 3.3 decrease in visual analogue scale score for wrist pain. No difference was found between techniques (total versus partial denervation), nor did different approaches influence outcome. The first carpometacarpal joint showed a decrease for visual analogue scale score for pain of 5.4. Patient satisfaction with the treatment result was 83 percent and 82 percent, respectively. Reported pain in finger joints decreased 96 percent in the metacarpophalangeal joints, 81 percent in the proximal interphalangeal joint, and 100 percent in the distal interphalangeal joint. The only reported case in the metacarpophalangeal joint of the thumb reported an increase of 37 percent.

Conclusions:
Only denervation of the metacarpophalangeal joint of the thumb reported an increase in pain; however, this was a single patient. Wrist and first carpometacarpal joint and finger joint denervation have a high satisfaction rate and decrease the pain. There was no difference between techniques.
Clinical Applications of Meshed Multilayered Anatomical Models by Low-Cost Three-Dimensional Printer
Authors: Mitsuno Daisuke , Ueda Koichi , Nuri Takashi , Katayama Misato 
Published: November 2021

Summary:
In recent years, even low-cost fused deposition modeling–type three-dimensional printers can be used to create a three-dimensional model with few errors. The authors devised a method to create a three-dimensional multilayered anatomical model at a lower cost and more easily than with established methods, by using a meshlike structure as the surface layer. Fused deposition modeling–type three-dimensional printers were used, with opaque polylactide filament for material. Using the three-dimensional data-editing software Blender (Blender Foundation, www.blender.org) and Instant Meshes (Jakob et al., https://igl.ethz.ch/projects/instant-meshes/) together, the body surface data were converted into a meshlike structure while retaining its overall shape. The meshed data were printed together with other data (nonmeshed) or printed separately. In each case, the multilayer model in which the layer of the body surface was meshed could be output without any trouble. It was possible to grasp the positional relationship between the body surface and the deep target, and it was clinically useful. The total work time for preparation and processing of three-dimensional data ranged from 1 hour to several hours, depending on the case, but the work time required for converting into a meshlike shape was about 10 minutes in all cases. The filament cost was $2 to $8. In conclusion, the authors devised a method to create a three-dimensional multilayered anatomical model to easily visualize positional relationships within the structure by converting the surface layer into a meshlike structure. This method is easy to adopt, regardless of the available facilities and economic environment, and has broad applications.
Rhinogoniometer: Validation of an Instrument for Rhinoplasty
Authors: Silva Eduardo Nascimento , dos Santos Therency Kamila , Ferreira Lydia Masako 
Published: November 2021

Summary:
The position of the lower lateral cartilages is directly related to good nasal functionality. When these cartilages exhibit cephalic malposition, the angle of divergence between cartilages is usually less than 60 degrees, which can cause external nasal valve insufficiency. The objective of this study was to validate the rhinogoniometer, an innovative surgical instrument that allows for diagnosing the position of this cartilage intraoperatively. In the intraoperative period, the angle of divergence, which is the angle formed between the two lateral branches of the lower lateral cartilages, was measured in 31 primary rhinoplasty patients. The rhinogoniometer measurement was compared with that of the computerized analysis, and the reproducibility of measurements with the rhinogoniometer between two different surgeons was determined. When comparing the values obtained by the two methods, a significant difference was found (p = 0.034). On average, the angles measured by the rhinogoniometer were 3.7 degrees smaller than the measurements made by the software. It was observed that when the angles measured by both methods were above 75 degrees, the differences between the two measurements were higher (p = 0.022). However, for angles up to 75 degrees, the measurement using the rhinogoniometer was, on average, 0.79 degrees higher than the measurement taken by the software. When the difference in angles obtained by the two methods between different surgeons was evaluated, there was a significant difference (p < 0.023). In conclusion, at angles up to 75 degrees, the rhinogoniometer showed a negligible difference of 0.79 degrees higher than the measurement obtained via software. Measurements with the rhinogoniometer were also shown to be reproducible with different surgeons.
Senotherapeutic Drugs: A New Avenue for Skincare?
Authors: Lee Ben P. , Harries Lorna W. 
Published: November 2021

Summary:
Skin aging is an outward manifestation of other cellular and molecular aging processes occurring elsewhere in the body. These processes are known collectively as the “hallmarks” of aging, which are a series of basic health maintenance mechanisms that fail over time. Cellular senescence is one of the most studied of the hallmarks of aging; senescent cells accumulate over time and are major drives of the aging process. Here, we discuss the impact of cellular senescence in the context of skin aging, and discuss the emerging landscape of interventions designed for their selective removal by targeted cell death (senolytics) or rejuvenation (senomorphics). We discuss the serotherapeutic strategies that are currently under investigation for systemic aging, which may bring eventual benefits for skin health. Next, we discuss a newly discovered hallmark of aging, dysregulated mRNA processing, which can be targeted for the senomorphic effect. Finally, we highlight a new modality for manipulation of disrupted mRNA processing, oligonucleotide therapeutics. The emerging field of senotherapeutics is set to revolutionize how we view and treat skin aging, and senotherapies are now poised to become a new class of skincare interventions.
