Abstract
Background
Hospital-based stroke rehabilitation for stroke survivors in developing countries may be limited by staffing ratios and length of stay that could hamper recovery potential. Thus, a home-based, gamified rehabilitation system (i.e., IntelliRehab) was tested for its ability to increase cerebral blood flow (CBF), and the secondary impact of changes on the upper limb motor function and functional outcomes.

Objective
To explore the effect of IntelliRehab on CBF in chronic stroke patients and its correlation with the upper limb motor function.

Methods
Two-dimensional pulsed Arterial Spin Labelling (2D-pASL) was used to obtain CBF images of stable, chronic stroke subjects (n = 8) over 3-months intervention period. CBF alterations were mapped, and the detected differences were marked as regions of interest. Motor functions represented by Fugl-Meyer Upper Extremity Assessment (FMA) and Stroke Impact Scale (SIS) were used to assess the primary and secondary outcomes, respectively.

Results
Regional CBF were significantly increased in right inferior temporal gyrus and left superior temporal white matter after 1-month (p = 0.044) and 3-months (p = 0.01) of rehabilitation, respectively. However, regional CBF in left middle fronto-orbital gyrus significantly declined after 1-month of rehabilitation (p = 0.012). Moreover, SIS-Q7 and FMA scores significantly increased after 1-month and 3-months of rehabilitation. There were no significant correlations, however, between CBF changes and upper limb motor function.

Conclusions
Participants demonstrated improved motor functions, supporting the benefit of using IntelliRehab as a tool for home-based rehabilitation. However, within-participant improvements may have limited potential that suggests the need for a timely administration of IntelliRehab to get the maximum capacity of improvement.

Abstract
Background
Particulate matter (PM) emission caused by tobacco combustion leads to severe health burdens worldwide. Second-hand smoke exposure is extraordinarily high in enclosed spaces (e.g., indoor rooms, car cabins) and poses a particular threat to the health of vulnerable individuals (e.g., children, elderly, etc.). This study aimed to establish a new measuring platform and investigate PM emissions under four different ventilation conditions inside a car cabin without exposing any person to harmful tobacco smoke.

Methods
PM concentrations were measured during the smoking of 3R4F reference cigarettes in a Mitsubishi Space Runner (interior volume 3.709 m3). The cigarettes were smoked with a machine, eliminating exposure of the researchers. Cigarettes were extinguished 4.5 min after ignition, and PM measurements continued until 10 min after ignition.

Results
High mean PM concentrations were measured for cigarettes without ventilation after 4.5 min (PM10: 1150 µg/m3, PM2.5: 1132 µg/m3, PM1: 861.6 µg/m3) and after 10 min (PM10: 1608 µg/m3, PM2.5: 1583 µg/m3, PM1: 1133 µg/m3). 3R4F smoked under conditions with turned on ventilation resulted in reduction of PM compared to those smoked without ventilation after 4.5 min (PM10:-47.5 to -58.4%, PM2.5:-47.2 to -58%, PM1:-39.6 to -50.2%) and after 10 min (PM10:-70.8 to -74.4%, PM2.5:-70.6 to -74.3%, PM1:-64.0 to -68.0%). Cigarettes smoked without ventilation generated high PM peaks at 4.5 min (PM10: 2207 µg/m3, PM2.5: 2166 µg/m3, PM1: 1421 µg/m3) and at 10 min (PM10: 1989 µg/m3, PM2.5: 1959 µg/m3, PM1: 1375 µg/m3). PM peaks of cigarettes smoked under different ventilation modes varied at 4.5 min (PM10: 630-845 µg/m3, PM2.5: 625-836 µg/m3, PM1: 543 - 693 µg/m3) and 10 min (PM10: 124 - 130 µg/m3, PM2.5: 124 - 129 µg/m3, PM1: 118 - 124 µg/m3).

Conclusion
The new measuring platform provides a safer way for researchers to investigate PM emissions of cigarettes. These data are comparable to published research and show that smoking in a parked vehicle with the windows closed generates harmful PM emissions even when the vehicle ventilation is in operation. Future studies should be carried out using the new measuring platform investigating PM exposure and PM distribution of in-vehicle smoking under a wide range of conditions.

Abstract
Background
Mediastinoscope and laparoscope-assisted esophagectomy for esophageal cancer occasionally causes postoperative accumulation of pleural effusion despite the preservation of the mediastinal pleura. Transhiatal chest drainage has been reported to be useful for thoracic esophagectomy; however, its use in mediastinoscope and laparoscope-assisted esophagectomy remains unelucidated. This study aimed to evaluate the effectiveness and safety of transhiatal chest drainage in mediastinoscope and laparoscope-assisted esophagectomy.

Methods
This retrospective study included patients who underwent mediastinoscope and laparoscope-assisted esophagectomy for esophageal cancer from 2018 to 2021. Transhiatal chest drainage involved the insertion of a 19-Fr Blake® drain from the abdomen to the left thoracic cavity through the hiatus. We assessed its effectiveness and safety by the daily drainage output, accumulation of postoperative pleural effusion, frequency of postoperative thoracentesis, and other complications. The drainage group comprising 24 patients was compared with the non-drainage group comprising 13 patients, in whom a transhiatal chest drainage tube was not placed during mediastinoscope and laparoscope-assisted esophagectomy.

Results
The median daily output of the transhiatal chest drainage was 230 mL on day 1, 385 mL on day 2, and 313 mL on day 3. The number of patients with postoperative pleural effusion was significantly reduced from 10/13 (76.9%) in the non-drainage group to 4/24 (16.7%) in the drainage group (p = 0.001). The frequency of thoracentesis in the drainage group was significantly lower than that in the non-drainage group (p = 0.002). There were no significant differences in the occurrence of other postoperative complications.

Conclusions
Transhiatal chest drainage could evacuate pleural effusion effectively and safely after mediastinoscope and laparoscope-assisted esophagectomy.
Testing for coronarvirus disease 2019 before cardiac surgery—safe outcome of infected patients
Authors: Ivert Torbjörn , Dalén Magnus 
Published: August 2022

Abstract
Background
The aim was to analyze routine preoperative testing for coronavirus disease 2019 (COVID-19) performed to avoid infected cardiac surgical patients transmitting virus during the pandemic.

Methods
Every patient scheduled to undergo cardiac surgery from March 2020 through December 2021 had preoperative polymerase-chain-reaction (PCR) test for COVID-19 by nasopharynx swabs. Any history of COVID-19 was recorded.

Results
In 15 of 1870 patients (0.8%) with minimal or no airway symptoms unexpected positive PCR tests were detected, and surgery was deferred for two weeks. Totally 38 patients with negative tests had recovered without sequelae from previous COVID-19 a mean of 5 months before the operation. Sixteen patients (0.8%) developed airway symptoms within six weeks after the operation and had positive COVID-19 tests. Body Mass Index was higher and female gender, diabetes mellitus, chronic obstructive pulmonary disease and reduced left ventricular ejection fraction were more common in patients with than in those without COVID-19. Early postoperative outcomes did not differ significantly in patients with versus without COVID-19.

Conclusions
An unexpected preoperative positive COVID-19 test was detected in less than one percent of patients admitted for cardiac surgery during the pandemic. These operations were deferred to avoid transmission of virus in the hospital. Additionally, one percent of patients were diagnosed with positive COVID-19 tests within six weeks after the operation. There was no outbreak of COVID-19 among hospital staff or patients. All patients with COVID-19 before the operation were operated on safely and postoperative outcomes did not differ significantly compared with COVID-19 negative patients.
Rare ectopic thyroid tissue as multiple bilateral pulmonary nodules: a case report and literature review
Authors: Tan Jianfeng , Kuang Jun , Li Yong , Wang Ruian , Hu Shan , Guo Quanwei , Zhang Jianhua 
Published: August 2022

Abstract
Background
The prevalence of ectopic thyroid tissue is 1 in every 100,000 to 300,000 persons in the general population, and ectopic thyroid tissue in the bilateral lung lobes is even rarer. Due to its rarity, there is no definitive or standard guidance on the diagnosis and treatment of ectopic thyroid tissue presenting as multiple bilateral pulmonary nodules.

Case presentation
A 56-year-old woman presented with multiple bilateral pulmonary nodules, and the patient had a history of hyperthyroidism but had no symptoms of ectopic thyroid tissue. Computed tomography (CT) demonstrated multiple solid nodules in both lungs, and the largest nodule (sized 15 × 14 mm) was located in segment 5 of the upper left lung. The initial diagnosis based on imaging was metastatic malignancies. Positron emission tomography-computed tomography (PET-CT) showed multiple bilateral intrapulmonary nodules that had slightly increased metabolism (SUVmax 1.7). The largest pulmonary nodule and another nodule in the left lung were resected by video-assisted thoracoscopy surgery (VATS). The pathological and immunohistochemical (IHC) examinations confirmed a diagnosis of ectopic thyroid tissue. No postoperative adjuvant therapy was given, and the patient was discharged 3 days after the operation and had regular follow-up examinations.

Conclusion
The diagnosis of ectopic thyroid tissue in the bilateral lung lobes is extremely difficult and should be considered carefully. PET-CT and surgical resection of intrapulmonary nodules are alternatives for clinicians in diagnosing ectopic thyroid tissue. Regular postoperative follow-up is needed.

Published: August 2022

AbstractBackgroundBronchial anastomotic dehiscence is considered one of the most catastrophic early airway complications post-transplant. The presence of a partial dehiscence can also cause further complications such as a fistula between the bronchus and the pleural membrane. Platelet-rich plasma (PRP) is known to significantly enhance the healing process and is being used in the treatment of various conditions, however, so far, there are no reports of the use of PRP in the treatment of bronchial anastomotic dehiscence fistula.Case presentationWe present a 37-year-old male, with non-cystic fibrosis bronchiectasis underwent bilateral lung transplantation. The patient developed partial dehiscence of the right bronchial anastomosis that was complicated by a small bronchopleural fistula. Two bronchoscopic applications of autologous platelet-rich plasma were carried out. Follow-up a few weeks later showed complete closure and healing of the fistula.ConclusionsThis case report suggests that the treatment of post-lung transplant small bronchial anastomotic partial dehiscence fistula with PRP is safe and effective.

Abstract
Background
Pancreatic cancer is one of the most difficult cancers to detect early and most patients die from complications arising due to distant organ metastases. The lack of bona fide early biomarkers is one of the primary reasons for late diagnosis of pancreatic cancer. It is a multifactorial disease and warrants a novel approach to identify early biomarkers.

Methods
In order to characterize the proteome, Extracellular vesicles (EVs) isolated from different in vitro conditions mimicking tumor-microenvironment interactions between pancreatic cancer epithelial and stromal cells were analyzed using high throughput mass spectrometry. The biological activity of the secreted EVome was analyzed by investigating changes in distant organ metastases and associated early changes in the microbiome. Candidate biomarkers (KIF5B, SFRP2, LOXL2, and MMP3) were selected and validated on a mouse-human hybrid Tissue Microarray (TMA) that was specifically generated for this study. Additionally, a human TMA was used to analyze the expression of KIF5B and SFRP2 in progressive stages of pancreatic cancer.

Results
The EVome of co-cultured epithelial and stromal cells is different from individual cells with distinct protein compositions. EVs secreted from stromal and cancer cells cultures could not induce significant changes in Pre-Metastatic Niche (PMN) modulation, which was assessed by changes in the distant organ metastases. However, they did induce significant changes in the early microbiome, as indicated by differences in α and β-diversities. KIF5B and SFRP2 show promise for early detection and investigation in progressive pancreatic cancer. These markers are expressed in all stages of pancreatic cancer such as low grade PanINs, advanced cancer, and in liver and soft tissue metastases.

Conclusions
Proteomic characterization of EVs derived from mimicking conditions of epithelial and stromal cells in the tumor-microenvironment resulted in the identification of several proteins, some for the first time in EVs. These secreted EVs cannot induce changes in distant organ metastases in in vivo models of EV education, but modulate changes in the early murine microbiome. Among all the proteins that were analyzed (MMP3, KIF5B, SFRP2, and LOXL2), KIF5B and SFRP2 show promise as bona fide early pancreatic cancer biomarkers expressed in progressive stages of pancreatic cancer.

AbstractBackgroundHepatic macrophages regulate liver granuloma formation and fibrosis caused by infection withSchistosoma japonicum, with the manner of regulation dependent on macrophage activation state. Interleukin (IL)-37 may have immunomodulatory effects on macrophages. However, whether IL-37 can affect liver granuloma formation and fibrosis by affecting the polarization of macrophages inS. japonicuminfection remains unclear. The aim of this study was to investigate IL-37-affected macrophage polarization in liver granuloma formation and fibrosis inS. japonicuminfection.MethodsAn enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of IL-37 in the serum of patients with acuteS. japonicuminfection and in the serum of healthy people. Recombinant IL-37 (rIL-37), CPP-IgG2Fc-IL-37 and no CPP-IgG2Fc-IL-37 proteins were injected intoS. japonicum-infected mice every 3 days for a total of 6 times from day 24 post infection onwards. Subsequently, ELISA, quantitative reverse transcription-PCR, fluorescence-activated cell sorting and western blot were used to analyze whether IL-37 inhibits the formation of liver granulomas and the development of liver fibrosis by regulating the phenotypic transition of macrophages. Finally, the three IL-37 proteins and SIS3, a Smad3 inhibitor, were co-cultured in mouse peritoneal macrophages to explore the mechanism underlying the promotion of the polarization of M0 macrophages to the M2 phenotype by IL-37.ResultsSerum IL-37 levels were upregulated in schistosomiasis patients, and this increased level of IL-37 protein apparently alleviated the liver granuloma of mice in infection models. It also could induce liver and peritoneal macrophages to polarize to the M2 phenotype inS. japonicum-infected mice. TheS. japonicum-infected mice injected with CPP-IgG2Fc-IL-37 group exhibited the most obvious improvement in inflammatory reaction against the liver granuloma. The number and ratio of M2 macrophages in the liver and peritoneal cavity were significantly higher in the three IL-37 protein groups, especially in the CPP-IgG2Fc-IL-37 group, compared to the controls. Similar results were also found regarding liver function damage. IL-37 induced macrophage M2 polarization by promoting AMP-activated protein kinase (AMPK) phosphorylation in vitro. Among all groups, the activation of AMPK was most significant in the CPP-IgG2Fc-IL-37 group, and it was found that SMAD3 could enhance the anti-inflammatory function of IL-37.ConclusionsThe results show that IL-37 was able to promote the polarization of macrophages to the M2 phenotype, thereby inhibiting the development of schistosomiasis. In comparison to the rIL-37 protein, the CPP-IgG2Fc-IL-37 protein has the advantages of being effective in small doses and having fewer side effects and a better efficacy.Graphical Abstract

AbstractManagement of nanomaterials and nanosafety data needs to operate under the FAIR (findability, accessibility, interoperability, and reusability) principles and this requires a unique, global identifier for each nanomaterial. Existing identifiers may not always be applicable or sufficient to definitively identify the specific nanomaterial used in a particular study, resulting in the use of textual descriptions in research project communications and reporting. To ensure that internal project documentation can later be linked to publicly released data and knowledge for the specific nanomaterials, or even to specific batches and variants of nanomaterials utilised in that project, a new identifier is proposed: the European Registry of Materials Identifier. We here describe the background to this new identifier, including FAIR interoperability as defined by FAIRSharing, identifiers.org, Bioregistry, and the CHEMINF ontology, and show how it complements other identifiers such as CAS numbers and the ongoing efforts to extend the InChI identifier to cover nanomaterials. We provide examples of its use in various H2020-funded nanosafety projects.

Abstract
Background
Participation rates in health surveys, recognized as an important quality dimension, have been declining over the years, which may affect representativeness and confidence in results. The Portuguese national health examination survey INSEF (2015) achieved a participation rate of 43.9%, which is in line with participation rates from other similar health examination surveys. The objective of this article is to describe how local teams of survey personnel conducted the survey, describing strategies used to solve practical survey problems and to try to increase the participation rate.

Methods
After a literature search, informal interviews were conducted with 14 public health officials from local health examination teams, regional and central authorities. Forty-one of the local staff members (survey personnel) also filled in a short questionnaire anonymously. The interviews and self-administered questionnaires were analysed using mixed methods, informed by thematic analysis.

Results
The local teams believed that the detailed manual, described as a “cookbook for making a health examination survey”, made it possible to maintain high scientific standards while allowing for improvising solutions to problems in the local context. The quality of the manual, supported by a series of training workshops with the central research and support team, gave the teams the confidence and knowledge to implement local solutions. Motivation and cohesion within the local teams were among the goals of the training process.
Local teams felt empowered by being given large responsibilities and worked hard to incite people to attend the examination through a close and persuasive approach.
Local teams praised their INSA contacts for being available for assistance throughout the survey, and said they were inspired to try harder to reach participants to please their contacts for interpersonal reasons.

Conclusions
The theory of organizational improvisation or bricolage, which means using limited resources to solve problems, was useful to discuss and understand what took place during INSEF.
A detailed manual covering standard procedures, continuous monitoring of the data collection and face-to-face workshops, including role-play, were vital to assure high scientific standards and high participation rates in this health examination survey. Close contacts between the central team and local focal points in all regions and all survey sites were key to accommodating unexpected challenges and innovative solutions.
