Authors: Doody Owen , Lombard John , Delamere Tara , Rabbitte Mary 
Published: May 2024

Abstract
Background
Nursing homes and other long-term care services account for a disparate share of COVID-19 cases and casualties worldwide. During COVID-19 there is a distinct need to preserve a holistic view of the wellbeing of residents of nursing homes, be mindful of their rights as citizens, and to be aware of protecting residents from infection. The delivery of health and social care throughout a pandemic must remain person-centred and adhere to a human rights-based approach.

Methods
This study aimed to capture nursing home residents, their families and staff’s perspective of the nursing homes residents experience, approaches of staff and the nursing home environment. An online survey was distributed via stakeholder networks and online platforms across Ireland. This study was performed and reported in line with the Consensus-Based Checklist for Reporting of Survey Studies (CROSS).

Results
25 residents, 42 family members and 51 staff completed the survey (n = 118). Across the domains measured all but one aspect scored above 50% (residents get up and go to bed when they want 41.5%) with the highest score of 89.1% scored for the nursing home is comfortable and well-kept. Results highlight evidence of positive experiences and endeavours to preserve social connections, residents were in a safe place cared for by staff who did their best in a difficult position and who went above and beyond their duty of care. However, some families reported poor communication, no internet connections, not enough phones or tablets, and that staff were busy and unable at times to assist residents who needed help using phones/tablets.

Conclusion
This study highlights the importance of human rights and how they ought to inform and shape the advancement of public health advice and policy documents. Overall, nursing home residents, their families and staff reported favourably on the study measures. However, issues pertaining to communication are essential and there is a need to address issues such as the provision of accurate timely information, communication infrastructure and resources, and inconsistencies in communications. Of note is that while healthcare professionals have a duty to uphold the rights of nursing home residents, they themselves have human rights which must also be protected and supported.
Infection prevention practice in home healthcare: a mixed-method study in two Swiss home healthcare organisations
Authors: Brockhaus Lisa , Lötscher Claudia , Labhardt Niklaus Daniel 
Published: May 2024

Abstract
Background
Infection prevention and control (IPC) research has long neglected the home healthcare sector with its unique challenges. This study aimed to gain an understanding of the barriers to the implementation of infection prevention practices relevant to this setting, the related attitudes, perceived relevance and priorities from the home healthcare worker perspective in Switzerland.

Methods
The mixed-method study involved semi-structured interviews (n = 18) and an anonymous web-based survey (n = 144) among nursing assistants and nurses from two home healthcare organizations in northwest Switzerland. Questions in both sub-studies focused on perceived challenges to infection prevention practices, perceived relevance, and related attitudes and mitigation strategies. Using an exploratory-sequential design, survey questions were designed to quantify and complement the findings from the interview study.

Results
Healthcare workers in these two organisations felt adequately protected, trained and supported by their organisations regarding IPC (survey agreement rates > 90%). General challenges to IPC in the home environment most agreed on were lack of cleanliness, lack of space, and the priorities of the patient to be respected (survey agreement rates 85.4%, 77.1%, and 70.8%, respectively). Practices and perceived challenges in the case of colonisation with multi-drug resistant organisms (MDRO) and potentially infectious diarrheal or respiratory illnesses varied highly regarding information transfer, use of protective equipment, and use and disinfection practices of multi-use equipment. Challenges to hand hygiene, sharps safety, waste management and decontamination of equipment did not feature as a prominent concern.

Conclusions
This study is the first to characterise the implementation of infection prevention practices and the related challenges in home healthcare in Switzerland. Home healthcare workers describe various challenges related to infection prevention practices as largely manageable in their work routine, and generally show satisfaction with the support provided by their organisations regarding IPC precautions. Key findings regarding challenges amenable to interventions include uncertainty and inconsistency regarding the management of MDRO colonisation and acute illnesses, and gaps in information transfer. Those challenges may benefit from both organisational interventions and further research into the level of precautions that are appropriate to the home healthcare setting.
Enhancing clinical utility: deep learning-based embryo scoring model for non-invasive aneuploidy prediction
Authors: Ma Bing-Xin , Zhao Guang-Nian , Yi Zhi-Fei , Yang Yong-Le , Jin Lei , Huang Bo 
Published: May 2024

Abstract
Background
The best method for selecting embryos ploidy is preimplantation genetic testing for aneuploidies (PGT-A). However, it takes more labour, money, and experience. As such, more approachable, non- invasive techniques were still needed. Analyses driven by artificial intelligence have been presented recently to automate and objectify picture assessments.

Methods
In present retrospective study, a total of 3448 biopsied blastocysts from 979 Time-lapse (TL)-PGT cycles were retrospectively analyzed. The “intelligent data analysis (iDA) Score” as a deep learning algorithm was used in TL incubators and assigned each blastocyst with a score between 1.0 and 9.9.

Results
Significant differences were observed in iDAScore among blastocysts with different ploidy. Additionally, multivariate logistic regression analysis showed that higher scores were significantly correlated with euploidy (p < 0.001). The Area Under the Curve (AUC) of iDAScore alone for predicting euploidy embryo is 0.612, but rose to 0.688 by adding clinical and embryonic characteristics.

Conclusions
This study provided additional information to strengthen the clinical applicability of iDAScore. This may provide a non-invasive and inexpensive alternative for patients who have no available blastocyst for biopsy or who are economically disadvantaged. However, the accuracy of embryo ploidy is still dependent on the results of next-generation sequencing technology (NGS) analysis.

Published: May 2024

Abstract
Backgrounds
Intraplacental choriocarcinoma (IC) is an extremely rare subtype of gestational choriocarcinoma. The long-term follow-up and reproductive outcomes of IC patients remain unclear. Here, we report a series of 14 cases and conduct a literature review to assess the fertility and recurrence results of this rare disease.

Results
Fourteen patients with pathologically confirmed IC treated in Peking Union Medical College Hospital between January 2002 and July 2022 were included in this study. Half of them had metastatic IC and were treated by chemotherapy with or without surgery. Only 1 patient had chemoresistant disease, but she achieved complete remission after immunotherapy. The median follow-up time was 45.5 months (range 4-192), and no recurrence occurred. One metastatic IC patient who achieved remission after chemotherapy had a full-term delivery. Among the 5 patients with fertility demands, 3 abandoned their pursuit of pregnancy because of “fear and worry about choriocarcinoma recurrence”. We reviewed a total of 89 cases of IC in English and Chinese literature from 1963 to 2022, and only 5 cases with subsequent pregnancy were reported, all of them were nonmetastatic IC cases.

Conclusions
IC is sensitive to chemotherapy and has good long-term remission and a low recurrence rate. Patients with metastatic or nonmetastatic IC can have good pregnancy results after treatment. Doctors should pay more attention to the psychology of these patients.

Published: May 2024

Abstract
Background
Primary mediastinal B-cell lymphoma (PMBL) and classical Hodgkin lymphoma (cHL) are distinct hematological malignancies of B-cell origin that share many biological, molecular, and clinical characteristics. In particular, the JAK/STAT signaling pathway is a driver of tumor development due to multiple recurrent mutations, particularly in STAT6. Furthermore, the XPO1 gene that encodes exportin 1 (XPO1) shows a frequent point mutation (E571K) resulting in an altered export of hundreds of cargo proteins, which may impact the success of future therapies in PMBL and cHL. Therefore, targeted therapies have been envisioned for these signaling pathways and mutations.

Methods
To identify novel molecular targets that could overcome the treatment resistance that occurs in PMBL and cHL patients, we have explored the efficacy of a first-in-class HSP110 inhibitor (iHSP110-33) alone and in combination with selinexor, a XPO1 specific inhibitor, both in vitro and in vivo.

Results
We show that iHSP110-33 decreased the survival of several PMBL and cHL cell lines and the size of tumor xenografts. We demonstrate that HSP110 is a cargo of XPO1wt as well as of XPO1E571K. Using immunoprecipitation, proximity ligation, thermophoresis and kinase assays, we showed that HSP110 directly interacts with STAT6 and favors its phosphorylation. The combination of iHSP110-33 and selinexor induces a synergistic reduction of STAT6 phosphorylation and of lymphoma cell growth in vitro and in vivo. In biopsies from PMBL patients, we show a correlation between HSP110 and STAT6 phosphorylation levels.

Conclusions
These findings suggest that HSP110 could be proposed as a novel target in PMBL and cHL therapy.

Published: May 2024

Abstract
Background
Snail-borne trematodes afflict humans, livestock, and wildlife. Recognizing their zoonotic potential and possible hybridization, a One Health approach is essential for effective control. Given the dearth of knowledge on African trematodes, this study aimed to map snail and trematode diversity, focusing on (i) characterizing gastropod snail species and their trematode parasites, (ii) determining infection rates of snail species as intermediate hosts for medically, veterinary, and ecologically significant trematodes, and (iii) comparing their diversity across endemic regions.

Methods
A cross-sectional study conducted in 2021 in Chiredzi and Wedza districts in Zimbabwe, known for high human schistosomiasis prevalence, involved malacological surveys at 56 sites. Trematode infections in snails were detected through shedding experiments and multiplex rapid diagnostic polymerase chain reactions (RD-PCRs). Morphological and molecular analyses were employed to identify snail and trematode species.

Results
Among 3209 collected snail specimens, 11 species were identified, including schistosome and fasciolid competent snail species. We report for the first time the invasive exotic snail Tarebia granifera in Zimbabwe, which was highly abundant, mainly in Chiredzi, occurring at 29 out of 35 sites. Shedding experiments on 1303 snails revealed a 2.24% infection rate, with 15 trematode species identified through molecular genotyping. Five species were exclusive to Chiredzi: Bolbophorus sp., Schistosoma mansoni, Schistosoma mattheei, Calicophoron sp., and Uvulifer sp. Eight were exclusive to Wedza, including Trichobilharzia sp., Stephanoprora amurensis, Spirorchid sp., and Echinostoma sp. as well as an unidentified species of the Plagiorchioidea superfamily. One species, Tylodelphys mashonensis, was common to both regions. The RD-PCR screening of 976 non-shedding snails indicated a 35.7% trematode infection rate, including the presence of schistosomes (1.1%) Fasciola nyanzae (0.6%). In Chiredzi, Radix natalensis had the highest trematode infection prevalence (33.3%), while in Wedza, R. natalensis (55.4%) and Bulinus tropicus (53.2%) had the highest infection prevalence.

Conclusions
Our xenomonitoring approach unveiled 15 trematode species, including nine new records in Zimbabwe. Schistosoma mansoni persists in the study region despite six mass deworming rounds. The high snail and parasite diversity, including the presence of exotic snail species that can impact endemic species and biomedically important trematodes, underscores the need for increased monitoring.

Generative design of compounds with desired potency from target protein sequences using a multimodal biochemical language model
Authors: Chen Hengwei , Bajorath Jürgen 
Published: May 2024

Abstract
Deep learning models adapted from natural language processing offer new opportunities for the prediction of active compounds via machine translation of sequential molecular data representations. For example, chemical language models are often derived for compound string transformation. Moreover, given the principal versatility of language models for translating different types of textual representations, off-the-beaten-path design tasks might be explored. In this work, we have investigated generative design of active compounds with desired potency from target sequence embeddings, representing a rather provoking prediction task. Therefore, a dual-component conditional language model was designed for learning from multimodal data. It comprised a protein language model component for generating target sequence embeddings and a conditional transformer for predicting new active compounds with desired potency. To this end, the designated “biochemical” language model was trained to learn mappings of combined protein sequence and compound potency value embeddings to corresponding compounds, fine-tuned on individual activity classes not encountered during model derivation, and evaluated on compound test sets that were structurally distinct from training sets. The biochemical language model correctly reproduced known compounds with different potency for all activity classes, providing proof-of-concept for the approach. Furthermore, the conditional model consistently reproduced larger numbers of known compounds as well as more potent compounds than an unconditional model, revealing a substantial effect of potency conditioning. The biochemical language model also generated structurally diverse candidate compounds departing from both fine-tuning and test compounds. Overall, generative compound design based on potency value-conditioned target sequence embeddings yielded promising results, rendering the approach attractive for further exploration and practical applications.

Scientific contribution
The approach introduced herein combines protein language model and chemical language model components, representing an advanced architecture, and is the first methodology for predicting compounds with desired potency from conditioned protein sequence data.

AbstractIn this paper, a modification of general linear positive operators introduced by Ibragimov and Gadjiev in 1970 is constructed. It is shown that this modification preserves exponential mappings and also contains modified Bernstein-, Szász- and Baskakov-type operators as special cases. The convergence properties of corresponding operators on $[ 0,\infty ) $

Authors: Hijab Anas A. , Shaakir Laith K. , Aljohani Sarah , Mlaiki Nabil 
Published: May 2024

AbstractThe current paper introduces a novel generalization of cone metric spaces called type I and type II composed cone metric spaces. Therefore, examples of a type I and type II composed cone metric space, which is not a cone metric space, are given. We establish some results of fixed point precisely about Hardy–Rogers type contraction on C2CMS and provide examples. Finally, we present an application of our results and how our results solve the Fredholm integral equation of generalizing several existing and unique fixed point theorems.
A social network analysis approach to assess COVID19-related disruption to substance use treatment and informal social interactions among people who use drugs in Scotland
Authors: McCann Mark , Bianchi Federica , Letina Srebrenka , Stewart Samantha , McLeod Katy , Tranmer Mark 
Published: May 2024

Abstract
Aims
To assess the extent of Coronavirus-related disruption to health and social care treatment and social interactions among people with lived or living experience of substance use in Scotland, and explore potential reasons for variations in disruption.

Design
Cross sectional mixed methods interview, incorporating a social network ‘egonet interview’ approach asking about whether participants had interactions with a range of substance use, health, social care or third sector organisations, or informal social interactions.

Setting
Five Alcohol and Drug Partnership Areas in Scotland.

Participants
57 (42% women) participants were involved in the study, on average 42 years old.

Measurements
Five-point Likert scale reporting whether interactions with a range of services and people had gotten much better, better, no different (or no change), worse, or much worse since COVID19 and lockdown. Ratings were nested within participants (Individuals provided multiple ratings) and some ratings were also nested within treatment service (services received multiple ratings). The nested structure was accounted for using cross classified ordinal logistic multilevel models.

Findings
While the overall average suggested only a slight negative change in interactions (mean rating 2.93), there were substantial variations according to type of interaction, and between individuals. Reported change was more often negative for mental health services (Adjusted OR = 0.93 95% CI 0.17,0.90), and positive for pharmacies (3.03 95% CI 1.36, 5.93). The models found between-participant variation of around 10%, and negligible between-service variation of around 1% in ratings. Ratings didn’t vary by individual age or gender but there was variation between areas.

Conclusions
Substance use treatment service adaptations due to COVID19 lockdown led to both positive and negative service user experiences. Social network methods provide an effective way to describe complex system-wide interaction patterns, and to measure variations at the individual, service, and area level.
Antitumour effects of artesunate via cell cycle checkpoint controls in human oesophageal squamous carcinoma cells
Authors: Mao Linlin , Deng Guodong , Li Mengfan , Lu Shih-Hsin , Jiang Wei , Yu Xiying 
Published: May 2024

AbstractArtesunate (ART), an effective antimalarial semisynthetic derivative of artemisinin, exhibits antitumour properties, but the mechanism(s) involved remain elusive. In this study, we investigated the antitumour effects of ART on human oesophageal squamous cell carcinoma (ESCC) cell lines. Treatment of ESCC cell lines with ART resulted in the production of excessive reactive oxygen species (ROS) that induced DNA damage, reduced cell proliferation and inhibited clonogenicity via G1-S cell cycle arrest and/or apoptosis in vitro. The administration of ART to nude mice with ESCC cell xenografts inhibited tumour formation in vivo. However, the cytotoxicity of ART strongly differed among the ESCC cell lines tested. Transcriptomic profiling revealed that although the expression of large numbers of genes in ESCC cell lines was affected by ART treatment, these genes could be functionally clustered into pathways involved in regulating cell cycle progression, DNA metabolism and apoptosis. We revealed that p53 and Cdk4/6-p16-Rb cell cycle checkpoint controls were critical determinants required for mediating ART cytotoxicity in ESCC cell lines. Specifically, KYSE30 cells with p53Mut/p16Mut were the most sensitive to ART, KYSE150 and KYSE180 cells with p53Mut/p16Nor exhibited intermediate responses to ART, and Eca109 cells with p53Nor/p16Nor exhibited the most resistance to ATR. Consistently, perturbation of p53 expression using RNA interference (RNAi) and/or Cdk4/6 activity using the inhibitor palbociclib altered ART cytotoxicity in KYSE30 cells. Given that the p53 and Cdk4/6-cyclin D1-p16-Rb genes are commonly mutated in ESCC, our results potentially shed new light on neoadjuvant chemotherapy strategies for ESCC.
Case of functional paraganglioma with intraoperative hypertensive crisis during robot-assisted thoracoscopic resection
Authors: Lachmann Björn , Schweigert Michael , Almeida Ana Beatriz , Spieth Stephanie , Rössel Thomas , Richter Torsten 
Published: May 2024

Abstract
Background
Mediastinal paragangliomas are rare. Their dangerousness may unfold during surgery, especially if hormonal activity was previously unknown. We report our experience with this case in context to the incidence and localization of atypically located mediastinal paragangliomas in the literature.

Case presentation
A 69-year-old female patient who was scheduled for thoracoscopic resection due to a posterior mediastinal tumor that had been progressing in size for several years and increasing symptoms. The induction of anesthesia, the ventilation of the lungs and the gas exchange after lung separation was uneventful. After initially stable circulatory conditions, there was a sudden increase in blood pressure up to 300/130 mmHg and tachycardia up to 130/min. This hypertensive phase was difficult to influence and required a rapid and consistent use of antihypertensive medication to bring down the blood pressure to reasonable values. The patient stabilized after tumor resection. The postoperative course was unremarkable. During the intraoperative blood pressure crisis, blood was drawn for analysis. These samples showed elevated concentrations of normetanephrine and metanephrine. The tumor subsequently presented as a catecholamine-secreting paraganglioma.

Conclusion
In order to avoid life-threatening blood pressure crises, hormone activity should be ruled out preoperatively in the case of mediastinal tumor, in which a paraganglioma could be considered in the differential diagnosis, especially if there are indications of hypertension in the medical history. Robotic-assisted thoracoscopic resection of the posterior mediastinal tumor was a feasible surgical method, even in the case of unexpected functional paraganglioma.
