Photodiagnosis and Photodynamic Therapy Jun 2024To assess the accuracy of Raman spectroscopy in distinguishing between patients with leukemia and healthy individuals. (Review)
Review
PURPOSE
To assess the accuracy of Raman spectroscopy in distinguishing between patients with leukemia and healthy individuals.
METHOD
PubMed, Embase, Web of Science, Cochrane Library, and CNKI databases were searched for relevant articles published from inception of the respective database to November 1, 2023. The pooled sensitivity (SEN), specificity (SPE), diagnostic odds ratio (DOR), positive likelihood ratio (PLR), negative likelihood ratio (NLR), were calculated along with their corresponding 95% confidence intervals (CI). A summary comprehensive receiver operating characteristic curve (SROC) was constructed and the area under the curve (AUC) was calculated. The degree of heterogeneity was tested and analyzed.
RESULTS
Fifteen groups of original studies from 13 articles were included. The pooled SEN and SPE were 0.93 (95% CI, [0.92 -0.93]) and 0.91(95% CI, [0.90-0.92]), respectively. The DOR was 613.01 (95%CI, [270.79-1387.75]), and the AUC was 0.99. The Deeks' funnel plot asymmetry test indicated no significant publication bias among the included studies (bias coefficient, 40.80; P = 0.13 <0.10). The meta-regression analysis findings indicated that the observed heterogeneity could be attributed to variations in sample categories and Raman spectroscopy techniques.
CONCLUSION
We confirmed that Raman spectroscopy has good accuracy in differentiating patients with leukemia from healthy individuals, and may become a means of leukemia screening in clinical practice. In the case of analysis based on live cells using surface-enhanced Raman spectroscopy (SERS) improved diagnostic efficacy was observed.

Review
The rapid increase of mcr-positive Klebsiella pneumoniae (K. pneumoniae) has received considerable attention and poses a major public health concern. Here, we systematically analyzed the global distribution of mcr-positive K. pneumoniae isolates based on published articles as well as publicly available genomes. Combining strain information from 78 articles and 673 K. pneumoniae genomes, a total of 1000 mcr-positive K. pneumoniae isolates were identified. We found that mcr-positive K. pneumoniae has disseminated widely worldwide, especially in Asia, with a higher diversity of sequence types (STs). These isolates were disseminated in 57 countries and were associated with 12 different hosts. Most of the isolates were found in China and were isolated from human sources. Moreover, MLST analysis showed that ST15 and ST11 accounted for the majority of mcr-positive K. pneumoniae, which deserve sustained attention in further surveillance programs. mcr-1 and mcr-9 were the dominant mcr variants in mcr-positive K. pneumoniae. Furthermore, a Genome-wide association study (GWAS) demonstrated that mcr-1- and mcr-9-producing genomes exhibited different antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs), thereby indicating a distinct evolutionary path. Notably, the phylogenetic analysis suggested that certain mcr-positive K. pneumoniae genomes from various geographical areas and hosts harbored a high degree of genetic similarities (<20 SNPs), suggesting frequent cross-region and cross-host clonal transmission. Overall, our results emphasize the significance of monitoring and exploring the transmission and evolution of mcr-positive K. pneumoniae in the context of "One health".

BACKGROUND
This research aimed to assess the effectiveness of preventive home visits (PHVs) in enhancing resilience and health-related outcomes among older adults living in the community.
METHODS
A comprehensive literature search was conducted in nine databases (PubMed, MEDLINE, CINAHL, Embase, Emcare, Web of Science (WOS), Scopus, PsycINFO and Cochrane Library. The search was undertaken between March 15 and 31, 2022 with subsequent updates performed on October 15, 2023 and April 10, 2024. This review also included grey literature sourced via Google, Google Scholar and backward citation searches.
RESULTS
Out of 5,621 records, 20 articles were found to meet the inclusion criteria with a total of 8,035 participants involved and the mean age ranged from 74.0 to 84.4 years. Using McMaster Critical Review Form for Quantitative Studies, we ascertained that the studies included in our analysis had moderate to high levels of quality. In addition to health-related outcomes, PHV interventions were also conducted to evaluate psychological effects (16 studies) and social outcomes (seven studies). Five studies conducted financial assessment to evaluate the costs of health and social care utilisation during PHV interventions. Regarding the results of the review, seven studies showed favourable outcomes, five indicated no effect and eight had equivocal findings. Only one study assessed resilience and determined that PHV had no effect on the resilience of the subjects.
CONCLUSION
This review found that the effectiveness of PHV interventions was uncertain and inconclusive. PHV interventions often prioritise health-related objectives. The incorporation of a holistic approach involving psychosocial health into PHV interventions is relatively uncommon. Due to the paucity of research on resilience as PHV outcome, we are unable to draw a conclusion on the effectiveness of PHV on resilience. Resilience should be prioritised as a psychological assessment in the future development of comprehensive PHV interventions, as it enables older adults to adapt, manage, and respond positively to adversities that may arise with age. Performing financial analysis such as costs and benefits analysis to incorporate the return on investment of PHV interventions is an added value for future research on this topic.

INTRODUCTION
Ambulance personnel are exposed to traumatic and stressful situations, which can increase the risk of mental health conditions, such as post-traumatic stress disorder (PTSD). High rates of PTSD have been found in ambulance personnel (Petrie et al., 2018), but no review is available to examine post-traumatic growth (PTG - positive psychological change following a trauma) in this population. This literature review provides an overview of the prevalence rates and facilitators that may contribute to PTG in ambulance personnel.
METHODS
A systematic search was conducted on EBSCOhost in January 2024 across the following six databases: Academic Search Ultimate, PsycINFO, PsycARTICLES, MEDLINE, ERIC and Cumulative Index to Nursing and Allied Health Literature (CINAHL) Ultimate.
RESULTS
Eleven papers were identified for this review. Pooled prevalence of PTG was moderate (52%), and facilitators for PTG were grouped into five categories: coping style/strategies, resilience, personality traits, gender and incident characteristics.
CONCLUSIONS
Numerous facilitators contributed to the development of PTG, although these did not arise in all papers. The quality of research ranged from satisfactory to excellent. Evidence suggested that adaptive coping style, high levels of resilience, the absence of a personality trait (neuroticism) and being female may facilitate PTG. Further research is needed to support the reliability of findings.

BACKGROUND
Contact tracing is a public health intervention implemented in synergy with other preventive measures to curb epidemics, like the coronavirus pandemic. The development and use of digital devices have increased worldwide to enhance the contact tracing process. The aim of the study was to evaluate the effectiveness and impact of tracking coronavirus disease 2019 (COVID-19) patients using digital solutions.
METHODS
Observational studies on digital contact tracing (DCT), published 2020-21, in English were identified through a systematic literature review performed on nine online databases. An ad hoc form was used for data extraction of relevant information. Quality assessment of the included studies was performed with validated tools. A qualitative synthesis of the findings is reported.
RESULTS
Over 8000 records were identified and 37 were included in the study: 24 modelling and 13 population-based studies. DCT improved the identification of close contacts of COVID-19 cases and reduced the effective reproduction number of COVID-19-related infections and deaths by over 60%. It impacted positively on societal and economic costs, in terms of lockdowns and use of resources, including staffing. Privacy and security issues were reported in 27 studies.
CONCLUSIONS
DCT contributed to curbing the COVID-19 pandemic, especially with the high uptake rate of the devices and in combination with other public health measures, especially conventional contact tracing. The main barriers to the implementation of the devices are uptake rate, security and privacy issues. Public health digitalization and contact tracing are the keys to countries' emergency preparedness for future health crises.

BACKGROUND
Fragrance substances are a frequent cause of contact allergy worldwide. Fragrance exposure varies by sex, age and possibly country, influenced by cosmetic availability, environmental conditions and cultural practices.
OBJECTIVES
To systematically review and gather prevalence of sensitization to fragrance mix I (FM I) and fragrance mix II (FM II) in consecutively patch-tested European dermatitis patients.
METHOD
A total of 4134 publications on patch test results of European dermatitis patients, published from 1981 to 2022, were systematically reviewed according to a previously registered and published PROSPERO protocol.
RESULTS
Eighty-four eligible original articles were analysed. Overall prevalence of sensitization to fragrance mix I (FM I) was 6.81% (95% CI: 6.37-7.28), and FM II was 3.64% (95% CI: 3.3-4.01). Sensitization to FM I was most prevalent in Central and Eastern Europe and to FM II in Western Europe. No clear time trends were observed. Among paediatric dermatitis patients, sensitization prevalence for FM I and FM II was 4.09% (95% CI: 3.37-4.96) and 2.17% (95% CI: 1.53-3.07).
CONCLUSION
The frequency of positive patch test results for both FMI and FMII remains high. Sensitization is also prevalent among children. Enhanced regulation and labelling of cosmetic products play a vital role in averting exposure and sensitization to fragrance allergens.

Parental verbal communication and modeling behavior during mealtimes shape offspring eating behavior - a systematic review with a focus on clinical implications for eating disorders.
OBJECTIVE
The aim of this review is to provide an overview of parental communication patterns during mealtimes, with a special emphasis being placed on the differences between families with and without a history of eating disorders.
METHODS
The systematic review was conducted according to the PRISMA statement. A systematic literature search was carried out in PubMed, PubPsych and PsycINFO and the results were assessed for eligibility by two independent raters using the PICOS criteria. Only studies that included a mealtime observation were considered suitable for analysis of both explicit and implicit parental communication.
RESULTS
The results of the review suggest that mothers communicate more, with more complexity, and with a greater variety of words with their children during mealtimes compared to fathers. The intention and type of communication is diverse and heterogeneous. In general, parents often tried to encourage their children to eat. Verbal modeling and co-eating appeared to be common behaviors. Mothers with a history of eating disorders expressed more negative emotions during eating than mothers without eating disorders. Findings regarding the use of positive comments and controlling speech are contradicting.
DISCUSSION
The review outlines major fields of parent-child communication and modeling behavior around family meals which might be relevant to investigate and integrate into models of intergenerational transmission of eating behavior and disordered eating.

Review
OBJECTIVE
This systematic review aims to evaluate existing evidence to investigate the therapeutic efficacy of M2 macrophage-derived exosomes in bone regeneration.
DESIGN
A comprehensive search between 2020 and 2024 across PubMed, Web of Science, and Scopus was conducted using a defined search strategy to identify relevant studies regarding the following question: "What is the impact of M2 macrophage-derived exosomes on bone regeneration?". Controlled in vitro and in vivo studies were included in this study. The SYRCLE tool was used to evaluate the risk of bias in the included animal studies.
RESULTS
This review included 20 studies published. Seven studies were selected for only in vitro analysis, whereas 13 studies underwent both in vitro and in vivo analyses. The in vivo studies employed animal models, including 163 C57BL6 mice and 73 Sprague-Dawley rats. Exosomes derived from M2 macrophages were discovered to be efficacious in promoting bone regeneration and vascularization in animal models of bone defects. These effects were primarily confirmed through morphological and histological assessments. This remarkable outcome is attributed to the regulation of multiple signaling pathways, as evidenced by the findings of 11 studies investigating the involvement of miRNAs in this intricate process. In addition, in vitro studies observed positive effects on cell proliferation, migration, osteogenesis, and angiogenesis. Heterogeneity in study methods hinders direct comparison of results across studies.
CONCLUSION
M2 macrophage-derived exosomes demonstrate remarkable potential for promoting bone regeneration. Further research optimizing their application and elucidating the underlying mechanisms can pave the way for clinical translation.

Review
Increasing evidence points out that Executive Functions (i.e., EFs) may be core mechanisms for the generation of resilient responses to adversity. A systematic review testing the relations between either affective (hot) and/or non-affective (cold) EFs (i.e., inhibition, flexibility and working memory updating) and resilience was conducted. A total of 449 articles were initially identified. After two steps of title-and-abstract (k = 449), and full-text reading filtering (k = 67), 11 studies were reviewed. Three studies included cold measures of working memory and supported significant positive relations between higher working memory functioning and higher trait resilience levels. One study included cold measures of inhibition and another one both hot and cold measures, with only the first one supporting a positive relation between more efficient inhibition and higher trait resilience levels. Finally, 7 studies measured flexibility in its cold and/or hot dimensions and overall supported significant relations between higher flexibility and higher levels of trait, process and outcome resilience measures. These results support the role of EFs performance to promote different forms of resilience. This review allows to identify different issues that need to be addressed in future research and highlight the need to integrate the analysis of all hot and cold EFs components to understand their role in the generation of resilience.

Review
Effectiveness of electroacupuncture on postoperative ileus prevention after abdominal surgery: A systematic review and trial sequential analysis of randomized controlled trials.
BACKGROUND
We aimed to verify the effectiveness of electroacupuncture on postoperative ileus prevention after abdominal surgery by meta-analysis and trial sequential analysis (TSA).
METHODS
From inception to May 14, 2024, PubMed, the Cochrane Library, Web of Science, and Embase databases were searched. TSA was used to determine an optimal sample size and control false-positive findings. The primary outcome was the time to first defecation (hours).
RESULTS
Fourteen studies were included, with 1105 participants. Meta-analysis and TSA revealed firm evidence for benefits that electroacupuncture shorted the time to first defecation (mean difference [MD] -12.73 h, I = 22%, P < 0.01), the time to first flatus (MD -7.03 h, I = 25%, P < 0.01), the time to start of sips of water (MD -12.02 h, I = 0%, P < 0.01), and the time to start of liquid diet (MD -12.97 h, I = 0%, P < 0.01) compared with usual care. While compared with sham electroacupuncture, meta-analysis and TSA also confirmed that electroacupuncture shortened the time to first defecation (MD -10.81 h, I = 31%, P = 0.02) and the time to first flatus (MD -10.81 h, I = 0%, P < 0.01). However, TSA revealed that firm evidence for benefit or futility was not reached for the length of hospital stay and the rates of postoperative prolonged ileus.
CONCLUSIONS
Electroacupuncture shortened the duration of postoperative ileus in patients undergoing abdominal surgery, and the adverse events related to electroacupuncture were minor. Further investigation of the effect of electroacupuncture on the risk of prolonged postoperative ileus is warranted in the future.
