“The magic triangle between bed, office, couch”: a qualitative exploration of job demands, resources, coping, and the role of leadership in remote work during the COVID-19 pandemic
Authors: Rohwer Elisabeth , Harth Volker , Mache Stefanie 
Published: February 2024

Abstract
Background
The COVID-19 pandemic has necessitated many employees to work from home with immediate effect for several months, regardless of their workplace preference or situation at home. Against this backdrop, this study explores perceived job demands and resources as well as the role of leadership and coping strategies of employees and managers with little or no prior experience with working from home in the altered work environment.

Methods
Based on the job demands-resources model, we developed an interview guide and conducted thirty-four semi-structured interviews. The interviews were transcribed and analyzed deductively-inductively using qualitative content analysis.

Results
Experienced job demands include, e.g., challenging, insufficient digital communication, and lack of social exchange, while greater flexibility and work-life balance were identified as valuable resources. Regarding the role of leadership, signaling trust, keeping regular contact, and supporting employees are important. To cope with the unforeseen yet persistent work situation, participants applied creative strategies by setting up offices at home with what they had at disposal. Differences were observed between employee and managerial perceptions as well as over time during the pandemic.

Conclusions
The results expand our knowledge about healthy remote work by adding specific demands, resources, and coping strategies employees and managers experienced during the extreme situation of the COVID-19 pandemic to the picture as well as specifying the role of leadership. Moreover, our findings provide a foundation for guidelines for healthy remote work design and collaboration in times of abrupt change and crises.

Abstract
Background
An optimal work environment for nurses is characterized primarily by appropriate staffing, good team relations, and support from the management staff. These factors are consistently associated with a positive assessment of patient safety by a hospital’s employees and a reduction in hospital mortality rates.

Aim
To understand the relationships between the work environment as perceived by nurses on the 30-day mortality of patients treated in Polish hospitals.

Background
An optimal work environment for nurses is characterized primarily by appropriate staffing, good team relations, and support from the management staff. These factors are consistently associated with a positive assessment of patient safety by a hospital’s employees and a reduction in hospital mortality rates.

Material and methods
The analysis used discharge data from 108,284 patients hospitalized in internal medicine and surgery departments in 21 hospitals (with 24/7 operations) in Poland. Administrative data included coded data to estimate 30-day mortality. A Nurses’ satisfaction questionnaire, including the PES-NWI scale and the SAQ questionnaire, was used to assess the work environment of nurses (n = 1,929). Correlations between variables were assessed using the Pearson coefficient. The analysis used a Poisson regression model, which belongs to the class of generalized linear models.

Results
A lower 30-day mortality rate amongst patients was found among those treated in hospitals where the personnel feel that they may question the decisions or actions of their superiors regarding the care provided (r = − 0.50); nurses are informed about changes introduced on the basis of reports about negligence and mistakes (r = − 0.50); the ward nurse is a good manager (r = − 0.41); nurses receive timely information from the head of the department that may have an impact on their work (r = − 0.41).

Conclusions
Factors related to care during hospital stay such as the organization of care at the ward level, analysis of care errors, the number of staff providing direct patient care, informing nurses about mistakes without punishment, and the possibility of nurses challenging the decisions or actions of superiors, which concerns care providing, affect the 30-day mortality of patients after the end of hospitalization in Polish hospitals.

Authors: Mo Fengyi , Hu Xiaorui , Ma Qing , Xing Lanfeng 
Published: February 2024

AbstractBackgroundGrowing focus on patient-centred care emphasizes humanistic skills and clinical narrative competence in nursing, particularly in assisted reproductive nursing. However, there is limited evidence to suggest the levels of nurse’ clinical narrative competence and humanistic care ability. This study aimed to investigate the clinical narrative competence and humanistic care ability of nurse specialists in assisted reproductive technology (ART) in China.MethodsThis cross-sectional study included nurses who obtained the ART specialist nurse certificate after nurse training in Zhejiang province assisted reproductive technology specialist nurse training base between 2017 and 2022. A demographic questionnaire, the Caring Ability Inventory (CAI) and Narrative Competence Scale (NCS) were used for data collection. Multivariate linear regression analysis was used to explore risk factors.ResultsA total of 122 participants (120 females, with a mean age of 33.35 ± 5.00 years) were included (response rate = 82.43%). NCS score and CAI score was 143.39 ± 19.24 (range: 27–189) and 198.42 ± 19.51 (range: 37–259) among nurse specialists in assisted reproductive technology, respectively. Multivariate linear regression analysis indicated that professional title (β = 20.003, 95%CI: 3.271–36.735, P = 0.020), and the CAI (β = 0.342, 95%CI: 0.180–0.540, P < 0.001) was independently associated with NCS. Head Nurse/ Team Leader/ Clinical Faculty had significantly higher CAI score than nurse (P = 0.006).ConclusionsThe clinical narrative competence and caring ability of nurse specialists in assisted reproductive technology was considered sufficient. Professional titles and work position were associated with clinical narrative competence. Enhancing clinical narrative competence can be considered as an effective strategy for promoting humanistic care ability.Trial registrationNot applicable.

Authors: Pal Upasana , Bachmann Denise , Pelzer Chiara , Christiansen Julia , Blank Lars M. , Tiso Till 
Published: February 2024

Abstract
Background
To contribute to the discovery of new microbial strains with metabolic and physiological robustness and develop them into successful chasses, Paracoccus pantotrophus DSM 2944, a Gram-negative bacterium from the phylum Alphaproteobacteria and the family Rhodobacteraceae, was chosen. The strain possesses an innate ability to tolerate high salt concentrations. It utilizes diverse substrates, including cheap and renewable feedstocks, such as C1 and C2 compounds. Also, it can consume short-chain alkanes, predominately found in hydrocarbon-rich environments, making it a potential bioremediation agent. The demonstrated metabolic versatility, coupled with the synthesis of the biodegradable polymer polyhydroxyalkanoate, positions this microbial strain as a noteworthy candidate for advancing the principles of a circular bioeconomy.

Results
The study aims to follow the chassis roadmap, as depicted by Calero and Nikel, and de Lorenzo, to transform wild-type P. pantotrophus DSM 2944 into a proficient SynBio (Synthetic Biology) chassis. The initial findings highlight the antibiotic resistance profile of this prospective SynBio chassis. Subsequently, the best origin of replication (ori) was identified as RK2. In contrast, the non-replicative ori R6K was selected for the development of a suicide plasmid necessary for genome integration or gene deletion. Moreover, when assessing the most effective method for gene transfer, it was observed that conjugation had superior efficiency compared to electroporation, while transformation by heat shock was ineffective. Robust host fitness was demonstrated by stable plasmid maintenance, while standardized gene expression using an array of synthetic promoters could be shown. pEMG-based scarless gene deletion was successfully adapted, allowing gene deletion and integration. The successful integration of a gene cassette for terephthalic acid degradation is showcased. The resulting strain can grow on both monomers of polyethylene terephthalate (PET), with an increased growth rate achieved through adaptive laboratory evolution.

Conclusion
The chassis roadmap for the development of P. pantotrophus DSM 2944 into a proficient SynBio chassis was implemented. The presented genetic toolkit allows genome editing and therewith the possibility to exploit Paracoccus for a myriad of applications.

Abstract
Background
Clear cell renal cell carcinoma (ccRCC) is the most prevalent kidney cancer with high aggressive phenotype and poor prognosis. Accumulating evidence suggests that circRNAs have been identified as pivotal mediators in cancers. However, the role of circRNAs in ccRCC progression remains elusive.

Methods
The differentially expressed circRNAs in 4 paired human ccRCC and adjacent noncancerous tissues ccRCC were screened using circRNA microarrays and the candidate target was selected based on circRNA expression level using weighted gene correlation network analysis (WGCNA) and the gene expression omnibus (GEO) database. CircPDHK1 expression in ccRCC and adjacent noncancerous tissues (n = 148) were evaluated along with clinically relevant information. RT-qPCR, RNase R digestion, and actinomycin D (ActD) stability test were conducted to identify the characteristics of circPDHK1. The subcellular distribution of circPDHK1 was analyzed by subcellular fractionation assay and fluorescence in situ hybridization (FISH). Immunoprecipitation-mass spectrometry (IP-MS) and immunofluorescence (IF) were employed to evaluate the protein-coding ability of circPDHK1. ccRCC cells were transfected with siRNAs, plasmids or lentivirus approach, and cell proliferation, migration and invasion, as well as tumorigenesis and metastasis in nude mice were assessed to clarify the functional roles of circPDHK1 and its encoded peptide PDHK1-241aa. RNA-sequencing, western blot analysis, immunoprecipitation (IP) and chromatin immunoprecipitation (ChIP) assays were further employed to identify the underlying mechanisms regulated by PDHK1-241aa.

Results
CircPDHK1 was upregulated in ccRCC tissues and closely related to WHO/ISUP stage, T stage, distant metastasis, VHL mutation and Ki-67 levels. CircPDHK1 had a functional internal ribosome entry site (IRES) and encoded a novel peptide PDHK1-241aa. Functionally, we confirmed that PDHK1-241aa and not the circPDHK1 promoted the proliferation, migration and invasion of ccRCC. Mechanistically, circPDHK1 was activated by HIF-2A at the transcriptional level. PDHK1-241aa was upregulated and interacted with PPP1CA, causing the relocation of PPP1CA to the nucleus. This thereby inhibited AKT dephosphorylation and activated the AKT-mTOR signaling pathway.

Conclusions
Our data indicated that circPDHK1-encoded PDHK1-241aa promotes ccRCC progression by interacting with PPP1CA to inhibit AKT dephosphorylation. This study provides novel insights into the multiplicity of circRNAs and highlights the potential use of circPDHK1 or PDHK1-241aa as a therapeutic target for ccRCC.
Analgesic efficacy of an opioid-free postoperative pain management strategy versus a conventional opioid-based strategy following laparoscopic radical gastrectomy: an open-label, randomized, controlled, non-inferiority trial
Authors: Lin Zhimin , Chen Zhongbiao , Li Yongliang 
Published: February 2024

Abstract
Objective
In patients undergoing laparoscopic radical gastrectomy, the use of subcostal transversus abdominis plane block (STAPB) for completely opioid-free postoperative pain management lacks convincing clinical evidence.

Methods
This study included 112 patients who underwent laparoscopic radical gastrectomy at the 900TH Hospital of the Joint Logistics Support Force from October 2020 to March 2022. Patients were randomly divided into (1:1) continuous opioid-free STAPB (C-STAPB) group and conventional group. In the C-STAPB group, 0.2% ropivacaine (bilateral, 20 ml per side) was injected intermittently every 12 h through a catheter placed on the transverse abdominis plane for postoperative pain management. The conventional group was treated with a conventional intravenous opioid pump (2.5 μg/kg sufentanil and 10 mg tropisetron, diluted to 100 ml with 0.9% NS). The primary outcomes were the accumulative area under the curve of the numeric rating scale (NRS) score at 24 and 48 h postoperatively at rest and during movement. The secondary outcomes were postoperative recovery outcomes, postoperative daily food intake, and postoperative complications.

Results
After exclusion (n = 16), a total of 96 patients (C-STAPB group, n = 46; conventional group, n = 49) were included. We found there were no significant differences in the cumulative AUC of NRS score PACU-24 h and PACU-48 h between the C-STAPB group and conventional group at rest [(mean difference, 1.38; 95% CI, − 2.21 to 4.98, P = 0.447), (mean difference, 1.22; 95% CI, − 6.20 to 8.65, P = 0.744)] and at movement [(mean difference, 2.90; 95% CI, − 3.65 to 9.46; P = 0.382), (mean difference, 4.32; 95% CI, − 4.46 to 13.1; P = 0.331)]. The 95% CI upper bound of the difference between rest and movement in the C-STAPB group was less than the inferior margin value (9.5 and 14 points), indicating the non-inferiority of the analgesic effect of C-STPAB. The C-STAPB group had faster postoperative recovery profiles including earlier bowel movement, defecation, more volume of food intake postoperative, and lower postoperative nausea and vomiting compared to conventional groups (P < 0.001).

Conclusions
After laparoscopic radical gastrectomy, the analgesic effect of C-STAPBP is not inferior to the traditional opioid-based pain management model.

Authors: Li Rui , Yu Zhiyuan , Ye Jiahu , Liu Xin , Li Peiyu , Zhao Xudong 
Published: February 2024

Abstract
Background
Relevant reports on the surgical resection and prognosis of recurrent presacral tumors are limited. The objective of this study was to explore the outcomes associated with surgical resection of recurrent presacral tumors.

Methods
The data of patients with recurrent presacral tumors who received surgical resection in our hospital between June 2009 and November 2018 were retrospectively analyzed.

Results
Thirty-one patients, comprising 22 females and 9 males, with recurrent presacral lesions were included in our study. A posterior approach was utilized in 27 patients, an anterior approach in 1 patient, and a combined approach in 3 patients. Intraoperative complications occurred in 13 patients (41.9%), while postoperative complications occurred in 6 patients (19.4%). The length of hospital stay was significantly shorter in patients who underwent the posterior approach compared to those who underwent the anterior and combined approaches (P = 0.002). The operative time for the posterior approach was significantly shorter compared to both the anterior and combined approaches (P = 0.006). Temporary tamponade was performed for hemostasis in 4 patients, while staged resection was performed in 2 patients during the surgical treatment process. After a median follow-up period of 115.5 months, 5 patients with recurrent malignant presacral tumors succumbed to tumor recurrence after reoperation in our hospital.

Conclusions
Surgical resection remains the mainstream treatment for recurrent presacral tumors. The outcomes for recurrent benign presacral tumors after surgery demonstrate favorable results, whereas further enhancements are required to improve the outcomes for recurrent malignant presacral tumors after surgery.
Clinical application of the HM-1000 image processing for HER2 fluorescence in situ hybridization signal quantification in breast cancer
Authors: Peg Vicente , Moline Teresa , Roig Miquel , Saruta Yuko , Cajal Santiago Ramon y 
Published: February 2024

Abstract
Background
Accurate quantification of human epidermal growth factor receptor 2 (HER2) gene amplification is important for predicting treatment response and prognosis in patients with breast cancer. Fluorescence in situ hybridization (FISH) is the gold standard for the diagnosis of HER2 status, particularly in cases with equivocal status on immunohistochemistry (IHC) staining, but has some limitations of non-classical amplifications and such cases are diagnosed basing on additional IHC and FISH. This study investigated the clinical utility of a novel super-resolution fluorescence microscopy technique for the better FISH signal visualization and HER2 FISH classification.

Methods
Fourteen breast cancer tissue samples were retrospectively collected between September 2018 and February 2022, and FISH HER2 signal quantification was evaluated by determining the HER2/chromosome 17 centromere (CEP17) ratio and the number of HER2 signals per nucleus in super- versus conventional-resolution images.

Results
Super-resolution images maintained the same overall HER2 diagnosis from routine, but HER2 FISH amplification changed negative to monosomy in two cases. Two Letrozole non-response relapses coincided to monosomy samples. The median number of HER2 signals per nucleus was 7.5 in super-resolution images and 4.0 in conventional-resolution images in HER2-positive samples and 2.8 and 2.1 signals per nucleus, respectively, in HER2-negative samples.

Conclusions
Super-resolution images improved signal visualization, including a significant difference in the number of countable HER2 and CEP17 signals in a single nucleus compared with conventional-resolution images. Increased accuracy of signal quantification by super-resolution microscopy may provide clinicians with more detailed information regarding HER2 FISH status that allows to better FISH classification such as HER2-low samples.
In vitro modulation of mTOR and mGlur5 influence α-synuclein accumulation
Authors: Xing Viktoria , Biggar Kyle , Ferguson Stephen S. G. , Hayley Shawn 
Published: February 2024

AbstractOne of the main hallmarks of Parkinson’s disease (PD) is abnormal alpha-synuclein (α-syn) aggregation which forms the main component of intracellular Lewy body inclusions. This short report used preformed α-syn fibrils, as well as an A53T mutant α-syn adenovirus to mimic conditions of pathological protein aggregation in dopaminergic human derived SH-SY5Y neural cells. Since there is evidence that the mTOR pathway and glutamatergic signaling each influence protein aggregation, we also assessed the impact of the mTOR inhibitor, rapamycin and the mGluR5 allosteric modulator, CTEP. We found that both rapamycin and CTEP induced a significant reduction of α-syn fibrils in SH-SY5Y cells and this effect was associated with a reduction in mTOR signaling and enhancement in autophagic pathway factors. These data support the possibility that CTEP (or rapamycin) might be a useful pharmacological approach to target abnormal α-syn accumulation by promoting intracellular degradation or enhanced clearance.
Dissecting the sequence and structural determinants guiding m6A deposition and evolution via inter- and intra-species hybrids
Authors: Shachar Ran , Dierks David , Garcia-Campos Miguel Angel , Uzonyi Anna , Toth Ursula , Rossmanith Walter , Schwartz Schraga 
Published: February 2024

Abstract
Background
N6-methyladenosine (m6A) is the most abundant mRNA modification, and controls mRNA stability. m6A distribution varies considerably between and within species. Yet, it is unclear to what extent this variability is driven by changes in genetic sequences (‘cis’) or cellular environments (‘trans’) and via which mechanisms.

Results
Here we dissect the determinants governing RNA methylation via interspecies and intraspecies hybrids in yeast and mammalian systems, coupled with massively parallel reporter assays and m6A-QTL reanalysis. We find that m6A evolution and variability is driven primarily in ‘cis’, via two mechanisms: (1) variations altering m6A consensus motifs, and (2) variation impacting mRNA secondary structure. We establish that mutations impacting RNA structure - even when distant from an m6A consensus motif - causally dictate methylation propensity. Finally, we demonstrate that allele-specific differences in m6A levels lead to allele-specific changes in gene expression.

Conclusions
Our findings define the determinants governing m6A evolution and diversity and characterize the consequences thereof on gene expression regulation.
