Patients’ cancer care perceptions conceptualized through the Cancer Experience Measurement Framework
Authors: Bourque Michaela A. , Loiselle Carmen G. 
Published: May 2022

Abstract
Background
Research on patients’ perceptions of cancer care often documents sub-optimal experiences. Cancer care quality issues include restricted service access, lack of care coordination, gaps in follow-up and “generic” rather than person-centered care. Recent reports underscore that proactively and periodically seeking user feedback is crucial for timely care quality improvement. The present study aimed to analyze and thematically organize a large amount of feedback from patients who had been treated for cancer within the last 6 months.

Methods
Randomly selected participants (N = 3,278) from 3 University-affiliated cancer centres in Montreal, Quebec, Canada completed the Ambulatory Oncology Patient Satisfaction Survey (AOPSS) and an open-ended question on their perceptions of the care they received. 692 participants responded to the latter. Guided by the Cancer Experience Measurement Framework (CEMF), their feedback was analyzed using a qualitative thematic approach.

Results
Cancer care perceptions included sub-themes of care access and coordination, continuity/transition, and perceived appropriateness/personalisation of care.
The most salient theme was captured by care access and coordination with 284 comments (44%) directly addressing these issues. The ways in which health care services were structured including setting, schedule, and location were often raised as cause for concerns. Issues surrounding cancer information/education, emotional support, and physical comfort were frequently reported as unmet needs. In addition, limited access to cancer services led patients to seek alternatives such as going to emergency departments and/or private care.

Conclusions
These findings are timely as they show that most patients are well aware of quality issues in cancer care and are willing to report candidly on these. Patient feedback also underscore the importance for cancer care institutions to periodically gather patient-reported data so that systems can re-calibrate their service offerings according to these data. Ultimately, patient reports will translate into enhanced quality, personalization, and safer cancer care provision.
What is needed for continuity of care and how can we achieve it? – Perceptions among multiprofessionals on the chronic care trajectory
Authors: Ljungholm Linda , Edin-Liljegren Anette , Ekstedt Mirjam , Klinga Charlotte 
Published: May 2022

Abstract
Background
Continuity of care (CoC) implies delivery of services in a coherent, logical and timely fashion. Continuity is conceptualized as multidimensional, encompassing three specific domains – relational, management and informational continuity – with emphasis placed on their interrelations, i.e., how they affect and are affected by each other. This study sought to investigate professionals’ perceptions of the prerequisites of CoC within and between organizations and how CoC can be realized for people with complex care needs.

Methods
This study had a qualitative design using individual, paired and focus group interviews with a purposeful sample of professionals involved in the chain of care for patients with chronic conditions across healthcare and social care services from three different geographical areas in Sweden, covering both urban and rural areas. Transcripts from interviews with 34 informants were analysed using conventional content analysis.

Results
CoC was found to be dependent on professional and cross-disciplinary cooperation at the micro, meso and macro system levels. Continuity is dependent on long-term and person-centred relationships (micro level), dynamic stability in organizational structures (meso level) and joint responsibility for cohesive care and enabling of uniform solutions for knowledge and information exchange (macro level).

Conclusions
Achieving CoC that creates coherent and long-term person-centred care requires knowledge- and information-sharing that transcends disciplinary and organizational boundaries. Collaborative accountability is needed both horizontally and vertically across micro, meso and macro system levels, rather than a focus on personal responsibility and relationships at the micro level.
Physicians’ perspectives and future vision on disability assessments by phone during the COVID-19 pandemic: a cross-sectional survey
Authors: Baart Nadia , Hoving Jan Lucas , Donker-Cools Birgit Helena Petra Maria 
Published: May 2022

Abstract
Background
Physicians, who perform disability assessments for the Dutch Social Security Institute, were urged to conduct phone consultations from their homes to prevent the spread of COVID-19. The purpose of the study was to evaluate the perspectives of physicians regarding phone consultations during the COVID-19 pandemic. Additionally, to explore physicians’ views on a more widespread future use of phone consultations in the context of work disability assessments.

Methods
An electronic survey conducted from June to August 2020 included 41 statements categorized into themes previously identified in both the literature on physicians’ phone consultations and emerging from daily practice. All 1081 physicians working at the Dutch Social Security Institute were invited by e-mail to participate in the survey. Participants indicated on a 5-point Likert scale whether they strongly disagreed, disagreed, neither agreed nor disagreed, agreed or strongly agreed with the statements. The collected data were analysed using descriptive statistics.

Results
In general, physicians had become accustomed to perform phone consultations. Negative experiences included difficulties in getting an impression of patients and assessing patients’ functional limitations. About half of physicians found that phone consultations took more effort, 61% asked more questions due to no direct patient observations. According to 67%, it is mostly necessary to perform an in-person consultation to adequately assess functional limitations of a patient with persistent medically unexplained physical symptoms. A great majority did not prefer telephone consultations to in-person consultations. However, more than half of physicians perceive a greater preference for phone consultations in the future than previously. 56% thought that replacement of in-person consultations with phone consultations in the future might lead to more complaints.

Conclusions
Perspectives and future views varied among physicians performing disability assessments by phone. A majority of physicians experienced difficulties with different aspects of the assessment. Despite these difficulties, most physicians support to continue the wider use of phone consultations. To improve remote disability assessments it is required to gain more insights into conditions under which a phone assessment can be as diligent as an in-person assessment.

Published: May 2022

Abstract
Background
It was urgent and necessary to synthesize the evidence for vaccine effectiveness (VE) against SARS-CoV-2 variants of concern (VOC). We conducted a systematic review and meta-analysis to provide a comprehensive overview of the effectiveness profile of COVID-19 vaccines against VOC.

Methods
Published randomized controlled trials (RCTs), cohort studies, and case-control studies that evaluated the VE against VOC (Alpha, Beta, Gamma, Delta, or Omicron) were searched until 4 March 2022. Pooled estimates and 95% confidence intervals (CIs) were calculated using random-effects meta-analysis. VE was defined as (1-estimate).

Results
Eleven RCTs (161,388 participants), 20 cohort studies (52,782,321 participants), and 26 case-control studies (2,584,732 cases) were included. Eleven COVID-19 vaccines (mRNA-1273, BNT162b2, ChAdOx1, Ad26.COV2.S, NVX-CoV2373, BBV152, CoronaVac, BBIBP-CorV, SCB-2019, CVnCoV, and HB02) were included in this analysis. Full vaccination was effective against Alpha, Beta, Gamma, Delta, and Omicron variants, with VE of 88.0% (95% CI, 83.0–91.5), 73.0% (95% CI, 64.3–79.5), 63.0% (95% CI, 47.9–73.7), 77.8% (95% CI, 72.7–82.0), and 55.9% (95% CI, 40.9–67.0), respectively. Booster vaccination was more effective against Delta and Omicron variants, with VE of 95.5% (95% CI, 94.2–96.5) and 80.8% (95% CI, 58.6–91.1), respectively. mRNA vaccines (mRNA-1273/BNT162b2) seemed to have higher VE against VOC over others; significant interactions (pinteraction < 0.10) were observed between VE and vaccine type (mRNA vaccines vs. not mRNA vaccines).

Conclusions
Full vaccination of COVID-19 vaccines is highly effective against Alpha variant, and moderate effective against Beta, Gamma, and Delta variants. Booster vaccination is more effective against Delta and Omicron variants. mRNA vaccines seem to have higher VE against Alpha, Beta, Gamma, and Delta variants over others.

Published: May 2022

Abstract
Background
As we are confronted with more transmissible/severe variants with immune escape and the waning of vaccine efficacy, it is particularly relevant to understand how the social contacts of individuals at greater risk of COVID-19 complications evolved over time. We described time trends in social contacts of individuals according to comorbidity and vaccination status before and during the first three waves of the COVID-19 pandemic in Quebec, Canada.

Methods
We used data from CONNECT, a repeated cross-sectional population-based survey of social contacts conducted before (2018/2019) and during the pandemic (April 2020 to July 2021). We recruited non-institutionalized adults from Quebec, Canada, by random digit dialling. We used a self-administered web-based questionnaire to measure the number of social contacts of participants (two-way conversation at a distance ≤2 m or a physical contact, irrespective of masking). We compared the mean number of contacts/day according to the comorbidity status of participants (pre-existing medical conditions with symptoms/medication in the past 12 months) and 1-dose vaccination status during the third wave. All analyses were performed using weighted generalized linear models with a Poisson distribution and robust variance.

Results
A total of 1441 and 5185 participants with and without comorbidities, respectively, were included in the analyses. Contacts significantly decreased from a mean of 6.1 (95%CI 4.9–7.3) before the pandemic to 3.2 (95%CI 2.5–3.9) during the first wave among individuals with comorbidities and from 8.1 (95%CI 7.3–9.0) to 2.7 (95%CI 2.2–3.2) among individuals without comorbidities. Individuals with comorbidities maintained fewer contacts than those without comorbidities in the second wave, with a significant difference before the Christmas 2020/2021 holidays (2.9 (95%CI 2.5–3.2) vs 3.9 (95%CI 3.5–4.3); P<0.001). During the third wave, contacts were similar for individuals with (4.1, 95%CI 3.4–4.7) and without comorbidities (4.5, 95%CI 4.1–4.9; P=0.27). This could be partly explained by individuals with comorbidities vaccinated with their first dose who increased their contacts to the level of those without comorbidities.

Conclusions
It will be important to closely monitor COVID-19-related outcomes and social contacts by comorbidity and vaccination status to inform targeted or population-based interventions (e.g., booster doses of the vaccine).

Published: May 2022

AbstractMicrobial cell factories for terpenoid synthesis form a less expensive and more environment-friendly approach than chemical synthesis and extraction, and are thus being regarded as mainstream research recently. Organelle compartmentalization for terpenoid synthesis has received much attention from researchers owing to the diverse physiochemical characteristics of organelles. In this review, we first systematically summarized various compartmentalization strategies utilized in terpenoid production, mainly plant terpenoids, which can provide catalytic reactions with sufficient intermediates and a suitable environment, while bypassing competing metabolic pathways. In addition, because of the limited storage capacity of cells, strategies used for the expansion of specific organelle membranes were discussed. Next, transporter engineering strategies to overcome the cytotoxic effects of terpenoid accumulation were analyzed. Finally, we discussed the future perspectives of compartmentalization and transporter engineering strategies, with the hope of providing theoretical guidance for designing and constructing cell factories for the purpose of terpenoid production.
Brain-targeted heptapeptide-loaded exosomes attenuated ischemia–reperfusion injury by promoting the transfer of healthy mitochondria from astrocytes to neurons
Authors: Liu Wei , Su Chang , Qi Yao , Liang Jia , Zhao Liang , Shi Yijie 
Published: May 2022

Abstract
Background
The exchange of mitochondria reportedly plays an important role in cell–cell communication in the central nervous system (CNS). The transfer of fragmented and dysfunctional astrocytic mitochondria into neurons and subsequent mitochondrial fusion often cause serious neuronal damage and cerebral ischaemic injury.

Methods
In this study, we prepared macrophage-derived exosomes laden with heptapeptide (Hep) as a dynamin-related protein-1 (Drp1)–fission 1 (Fis1) peptide inhibitor P110 to alleviate cerebral ischemia–reperfusion injury by reducing mitochondrial Drp1/Fis1 interaction-mediated astrocytic mitochondrial disorder and promoting the transfer of astrocyte-derived healthy mitochondria into neurons.

Results
The results demonstrated that Hep-loaded macrophage-derived exosomes (EXO-Hep) reduced mitochondrial damage in astrocytes by inhibiting the Drp1/Fis1 interaction after ischemia–reperfusion, ensuring the release of heathy astrocytic mitochondria and their subsequent transmission to neurons, alleviating mitochondria-mediated neuronal damage.

Conclusion
EXO-Hep significantly mitigated ischemic injury in a model of transient middle cerebral artery occlusion (tMCAO) by reducing the infarct area and improving neurological performance during the process of cerebral ischemia–reperfusion.

Published: May 2022

Abstract
Background
A strong nursing research agenda in Latin America is fundamental to universal health coverage. Nursing science can make important contributions to the health of Latin American people through knowledge generation that directly informs nursing practice, professional education, and health policy.

Methods
We used a cross-sectional survey design to assess nursing involvement in health systems and services research in Latin America in five priority areas: Policies and education related to nursing human resources; Structure, organization and dynamics of health systems and services; Science, technology, innovation, and information systems in public health; Health policies, governance, and social control; and Social studies in the health field.

Results
Nursing and midwifery participants (N = 856) from Latin American countries completed the survey. Respondents who reported conducting research focused primarily on Policies and Education related to Nursing Human Resources and Structure, Organization, and Dynamics of Health Systems and Services. Across the five priority areas, more nurses reported using research findings and/or being aware of research than conducting research.

Conclusions
Survey results indicate that nursing research in Latin America is currently disproportionately focused on nursing education and practice. More research focused on information technology, nurse’s impact on public health, and the threats posed by nurse migration is needed to better address health needs of Latin American populations.

Published: May 2022

Abstract
Background
Many eukaryote cells produce membrane-enclosed extracellular vesicles (EVs) to establish cell-to-cell communication. Plant-derived EVs (P-EVs) contain proteins, RNAs, lipids, and other metabolites that can be isolated from the juice, the flesh, and roots of many species.

Methods
In the present review study, we studied numerous articles over the past two decades published on the role of P-EVs in plant physiology as well as on the application of these vesicles in different diseases.

Results
Different types of EVs have been identified in plants that have multiple functions including reorganization of cell structure, development, facilitating crosstalk between plants and fungi, plant immunity, defense against pathogens. Purified from several edible species, these EVs are more biocompatible, biodegradable, and extremely available from many plants, making them useful for cell-free therapy. Emerging evidence of clinical and preclinical studies suggest that P-EVs have numerous benefits over conventional synthetic carriers, opening novel frontiers for the novel drug-delivery system. Exciting new opportunities, including designing drug-loaded P-EVs to improve the drug-delivery systems, are already being examined, however clinical translation of P-EVs-based therapies faces challenges.

Conclusion
P-EVs hold great promise for clinical application in the treatment of different diseases. In addition, despite enthusiastic results, further scrutiny should focus on unravelling the detailed mechanism behind P-EVs biogenesis and trafficking as well as their therapeutic applications.
Association between physical activity and infertility: a comprehensive systematic review and meta-analysis
Authors: Xie Fangfang , You Yanli , Guan Chong , Gu Yuanjia , Yao Fei , Xu Jiatuo 
Published: May 2022

Abstract
Background
Physical activity (PA) may protect against infertility by modulating the hypothalamic-pituitary–gonadal axis, thereby reducing gonadotropin levels, elevating immune function, and inhibiting inflammation and circulating sex hormones. However, whether PA reduces the risk of infertility remains largely unknown. We therefore conducted a systematic review and meta-analysis to determine the preventive effects of PA on infertility.

Methods
We searched PubMed, Cochrane Library, EMBASE, and CINAHL databases to retrieve published epidemiologic studies on the relationship between PA and infertility. Following the PRISMA guidelines, we selected English literature publishedprior to 11 April 2022, and assessed study quality using the Newcastle–Ottawa Scale. Our protocol, including the full methods employed for this review, is available on PROSPERO (ID = CRD42020143344).

Results
Six cohort studies and four case–control studies based on 708,965 subjects and 12,580 cases were eventually screened and retained. High levels of PA were shown to reduced risk of infertility relative to low levels (cumulative relative risk [RR] = 0.59, with a 95% confidence interval CI 0.49–0.71), and we reported results for cohort studies (RR = 0.63, 95% CI 0.50–0.79) and case–control studies (RR = 0.49, 95% CI 0.35–0.67). Our findings were comparable for men (RR = 0.65, 95% CI 0.41–1.04) and women (RR = 0.56, 95% CI 0.47–0.66). The meta-analysis of six risk estimates from five studies of low, moderate, and high PA levels showed that moderate PA may also reduce the risk of infertility compared with low PA (RR = 0.54, 95% CI 0.38–0.77). However, high PA also appeared to slightly augment the risk of infertility compared with moderate PA (RR = 1.31, 95% CI 1.08–1.59).

Conclusions
This present systematic review comprehensively reflected an inverse relationship between different levels of PA and infertility, and our meta-analysis showed that a moderate-to-high PA level significantly reduced the overall risk of infertility, and that this level of PA activity was a common protective factor. In addition, limited evidence suggested that compliance with international PA guidelines would greatly lower the risk of infertility (RR = 0.58, 95% CI 0.45–0.74; I2 = 0.0%). Future studies, however, need to be executed to further determine the frequency, optimal dosage, and duration required to effectively attenuate the risk of infertility.

Published: May 2022

Abstract
Background
Tumor-draining lymph nodes (TDLNs) are primary sites, where anti-tumor lymphocytes are primed to tumor-specific antigens and play pivotal roles in immune responses against tumors. Although adoptive cell therapy (ACT) using lymphocytes isolated from TDLNs were reported, characterization of immune activity of lymphocytes in TDLNs to tumor cells was not comprehensively performed. Here, we demonstrate TDLNs to have very high potential as cell sources for immunotherapy.

Methods
Lymphocytes from TDLNs resected during surgical operation were cultured with autologous-tumor cells for 2 weeks and evaluated tumor-reactivity by IFNγ ELISPOT assay. We investigated the commonality of T cell receptor (TCR) clonotypes expanded by the co-culture with tumor cells with those of tumor infiltrating lymphocytes (TILs).

Results
We found that that TCR clonotypes of PD-1-expressing CD8+ T cells in lymph nodes commonly shared with those of TILs in primary tumors and lymphocytes having tumor-reactivity and TCR clonotypes shared with TILs could be induced from non-metastatic lymph nodes when they were co-cultured with autologous tumor cells.

Conclusion
Our results imply that tumor-reactive effector T cells were present even in pathologically non-metastatic lymph nodes and could be expanded in vitro in the presence of autologous tumor cells and possibly be applied for ACT.
