Published: September 2022

Purpose Monofocal intraocular lenses (IOLs) used in cataract surgery are designed to improve visual acuity (VA). The available evidence of new monofocal IOLs” functional benefits is limited. The aim of this meta-analysis was to analyze the improvement in VA using Tecnis Eyhance monofocal IOLs compared to standard monofocal IOLs Tecnis ZCB00. Methods MEDLINE, Web of Science and Scopus were searched for studies assessing improvement in intermediate VA using Tecnis Eyhance IOLs versus Tecnis ZCB00 IOLs. Studies evaluating post-operative VA in patients who underwent cataract surgery were selected. This meta-analysis followed PRISMA guidelines and was registered in PROSPERO. The Cochrane Risk of Bias Tool 2.0. was used to assess the methodological quality of the included studies, risk of selection bias and comparability of cohorts and outcomes. Results The search resulted in 1153 articles. Five studies met the inclusion criteria and were included in the meta-analysis. A total of 604 eyes were evaluated, of which 309 received Tecnis Eyhance IOLs and 295 were implanted with Tecnis ZCB00 IOLs. Mean binocular distant-corrected intermediate VA with Tecnis Eyhance IOLs at 2 weeks-1 month showed a significant difference of −0,21 logMAR, p < 0.001; and mean binocular distance-corrected intermediate VA with Tecnis Eyhance IOLs at 6 months showed a significant difference of −0,11 logMAR, p < 0.001. Conclusion Near VA could not be assessed in this meta-analysis as it was measured in very few studies. Preliminary pooled evidence indicates that intermediate VA improved with Tecnis Eyhance IOLs. Further studies evaluating near VA and with longer follow-up are still necessary.

Introduction: The use of thin highly cross-linked polyethylene (HXLPE) liners in total hip arthroplasty (THA) allows utilisation of larger femoral heads. However, concern surrounding postoperative complications remains. This study aims to investigate rates of revision and re-admission associated with thin HXLPE liners at short-term follow-up. Methods: We retrospectively reviewed 3047 patients who underwent THA with a cementless modular acetabular implant with a 36-mm femoral head, and different thicknesses of HXPLE liners from 2011 to 2021. We identified 723 patients (23.7%) with a minimum 2-year follow-up and 206 patients (6.8%) with a minimum 5-year follow-up. Patients in the thin group (TG, n = 1020) received <5.1-mm liners with 52-mm size cups while patients in the non-thin group (NTG, n = 2027) received >5.1-mm liners with >52-mm size cups. Outcomes were compared using multi-variable logistic regressions while controlling for all significant demographic differences. Results: We found no significant differences in re-admission (3.9% vs. 4.3%, OR 0.97; 95% CI, 0.63–1.49; p = 0.874) and revision (2.5% vs. 3.2%, OR 0.72; 95% CI, 0.41–1.26; p = 0.246) rates between groups. The difference in fracture rate between groups was not significant, but the 1 recorded acetabular fracture (5%) occurred in the NTG. Although the rate of liner exchange was lower in the TG (1.1%) compared to the NTG (2.3%), the difference was not statistically significant (OR 0.51; 95% CI, 0.24–1.05; p = 0.068). Liners were exchanged for liner wear in 1 hip (1%), aseptic reasons in 38 hips (66%), and peri-prosthetic joint infection in 19 hips (33%). Conclusions: Patients undergoing THA with a thin liner were not significantly predisposed to higher rates of revision surgery or poorer clinical outcomes at short-term follow-up when compared to those who received a thicker liner. Consequently, further long-term studies regarding the utility of thin HXLPE implants in reducing complications should be pursued.

Authors: Gill Manmohit , Datta Dhruv , Gregory Paul , Austin Zubin 
Published: September 2022

Background: The Peel region in Southern Ontario is among the most ethnoculturally diverse and fastest growing areas in Canada. During the COVID-19 pandemic, the multicultural community of Brampton suffered one of the highest infection rates in Canada, in part because of the demographic and socioeconomic characteristics of the community. The role of pharmacists in supporting vaccine uptake in this linguistically, ethnically and religiously diverse community has not been adequately characterized. Methods: A qualitative case study approach was used, focusing on one of the major communities in Peel (Brampton). Interviews with community pharmacists and pharmacy staff directly involved in COVID-19 vaccine administration during the pandemic were undertaken to identify common experiences and trends related to providing care and support to this high-risk community. Constant comparative coding was used to identify common themes that can inform ongoing public health supports in future pandemics. Results: A total of 29 interviews were completed. Key themes that emerged included 1) the impact of operational, organizational and logistical issues on vaccine uptake in the community; 2) the negative influence of inconsistent messaging from public health and other experts during the pandemic; and 3) the identification of an emerging typology of “vaccine hesitancies” describing different reasons/motivations for avoiding COVID-19 vaccination and approaches taken by pharmacy staff to address these within a multicultural, multilingual practice context. Discussion: The COVID-19 vaccination campaign was unprecedented in its size, scope and speed, and community pharmacists were integral in this effort. The unique needs of ethnoculturally, linguistically and socioeconomically diverse communities like Brampton require further studies to examine ways in which the pharmacy profession can positively influence greater vaccine uptake, by increasing understanding of the diverse proliferation of vaccine hesitancies that emerged.
People’s Knowledge and Perceptions Towards Bee–Pollinators in the Southern Highlands, Tanzania: Conservation Implications and Strategies
Authors: Ojija Fredrick , Leweri Cecilia 
Published: September 2022

Background and research aims Bees are important pollinators of flowering wild plants and agricultural crops that contribute significantly towards food security, improving people’s livelihoods, and maintaining genetic diversity in plant communities. However, the decline of the bee population due to anthropogenic changes and limited knowledge of bees is threatening bee diversity, particularly in sub–Saharan Africa. Negative perceptions, that is, fear and disgust, are common emotions that lead to a lack of support for bee conservation. Understanding local people’s perceptions is vital as it can help in bee conservation decision making and proper protection actions. Methods We conducted the study in the Mbeya and Songwe regions of Tanzania to assess the knowledge and perception of local people about bee–pollinators and conservation using a structured questionnaire Results We found that the majority of respondents (91%) have heard about bees (χ2 = 6275, p < 0.001) and their conservation initiatives (71%), and about 84% of respondents consider bees to be important (χ2 = 168.9, p = 0.001). Moreover, Apis mellifera had the highest identification rate, with 52.7% of respondents. A binary logistic model revealed that respondents' knowledge of bee–pollinators and pollination is not influenced by their age (except for respondents aged 15–18 years, p = 0.012) and education level. While 74% of respondents claimed to be afraid of bees, 79% stated that bees are dangerous to humans. The most common cause is personal experience with bee stings. Poor farm management practices, for example, use of fire and deforestation, were noted by 79% of respondents as the most human activities threatening bee–pollinators. Conclusion Overall, the respondents were more familiar with A. mellifera compared to non–Apis bee species. Implications for conservation Thus, we suggest that implementation of pollinator management programs is vital to ensure their survival and reduce the perceived threat by dispelling myths and encouraging interest in bees.
Paramedic attitudes towards prehospital spinal care: a cross-sectional survey
Authors: McDonald Neil , Kriellaars Dean , Pryce Rob T. 
Published: September 2022

AbstractBackgroundThe optimal application of spinal motion restriction (SMR) in the prehospital setting continues to be debated. Few studies have examined how changing guidelines have been received and interpreted by emergency medical services (EMS) personnel. This study surveys paramedics’ attitudes, observations, and self-reported practices around the treatment of potential spine injuries in the prehospital setting.MethodsThis was a cross-sectional survey of a North American EMS agency. After development and piloting, the final version of the survey contained four sections covering attitudes towards 1) general practice, 2) specific techniques, 3) assessment protocols, and 4) mechanisms of injury (MOI). Questions used Likert-scale, multiple-choice, yes/no, and free-text responses. Exploratory factor analysis (EFA) was used to identify latent constructs within responses, and factor scores were analyzed by ordinal logistic regression for associations with demographic characteristics (including qualification level, gender, and years of experience). MOI evaluations were assessed for inter-rater reliability (Fleiss’ kappa). Inductive qualitative content analysis, following Elo & Kyngäs (2008), was used to examine free-text responses.ResultsTwo hundred twenty responses were received (36% of staff). Raw results indicated that respondents felt that SMR was seen as less important than in the past, that they were treating fewer patients than previously, and that they follow protocol in most situations. The EFA identified two factors: one (Judging MOIs) captured paramedics’ estimation that the presented MOI could potentially cause a spine injury, and another (Treatment Value) reflected respondents’ composite view of the effectiveness, importance, and applicability of SMR. Respondents with advanced life support (ALS) qualification were more likely to be skeptical of the value of SMR compared to those at the basic life support (BLS) level (OR: 2.40, 95%CI: 1.21–4.76,p = 0.01). Overall, respondents showed fair agreement in the evaluation of MOIs (k = 0.31, 95%CI: 0.09–0.49). Content analysis identified tension expressed by respondents between SMR-as-directed and SMR-as-applied.ConclusionResults of this survey show that EMS personnel are skeptical of many elements of SMR but use various strategies to balance protocol adherence with optimizing patient care. While identifying several areas for future research, these findings argue for incorporating provider feedback and judgement into future guideline revision.
Immune checkpoint inhibitors and their impact on liver enzymes and attenuation
Authors: Park Benjamin C. , Lee Aaron X. T. , Ye Fei , Turker Isik , Johnson Douglas B. 
Published: September 2022

Abstract
Background
Immune related adverse events impacting the liver are common from immune checkpoint inhibitor (ICI) therapy; however, there is little data regarding the subclinical impact of ICIs on liver inflammation. The study aims to determine whether ICI therapy affects liver attenuation and liver enzymes in melanoma patients with and without hepatic steatosis.

Methods
A retrospective, cohort study was conducted of patients with advanced melanoma treated with ICI therapy who received serial PET-CT scans at the Vanderbilt University Medical Center (VUMC). Primary outcomes included: liver attenuation measured by PET-CT/non-contrast CT and liver enzymes. Hepatic steatosis was diagnosed by radiologists on clinical imaging.

Results
Among 839 patients with advanced melanoma treated with ICIs, 81 had serial PET-CT scans approximately 12 months apart and long-term survival; of these 11 patients had pre-existing steatosis/steatohepatitis. Overall, ICI was not associated with significant increases in liver enzymes in all patients; modest decreases in liver enzymes were observed in patients with pre-existing steatosis/steatohepatitis. Similarly, liver attenuation did not change from baseline to post-treatment (58.44 vs 60.60 HU, + 2.17, p = 0.055).

Conclusions
ICIs may not chronically affect liver enzymes or liver attenuation, a non-invasive measure of liver fat content and inflammation, in the general population or in those with pre-existing steatosis/steatohepatitis.

AbstractBackgroundSevere graft versus host disease (GVHD) is the main reason for non-relapse mortality following allogeneic hematopoietic cell transplantation (HCT). We investigated the serum protein profiles of patients who had undergone HCT to identify predictive biomarkers of severe acute GVHD (aGVHD).MethodsSerum samples were collected for 30 patients from day − 7 to day + 14 of HCT. The serum levels of plasma beta2-microglobulin (β2-MG), soluble vascular cell adhesion molecule-1 (sVCAM-1), platelet factor 4, and TNFSF-14 were measured by ELISA as potential biomarkers following 310 cytokine profiling array.ResultsThe median age of the study patients was 53.5 years (range, 19–69). All grade and grade 2–4 aGVHD developed in 21 (70.0%) and 17 (56.7%) patients, respectively. Compared with their baseline levels on day − 7, β2-MG and sVCAM-1 were significantly increased on day + 14 of the HCT procedure (P = 0.028 andP < 0.001, respectively). Patients with a grade 2–4 severe aGVHD showed a significantly higher sVCAM-1 level at baseline (day-7) and at day + 14, compared with the other group with a grade 1 aGVHD or no aGVHD (P = 0.028 andP = 0.035, respectively).ConclusionHigher sVCAM- levels at baseline and on day + 14 in HCT patients could be a significant predictive biomarker of severe aGVHD.
Autonomy and health-related quality of life in adolescents
Authors: Eriksson Mårten , Boman Eva , Svedberg Pia 
Published: September 2022

Abstract
Background
Autonomy is recognized as important for individual well-being and constitutes one dimension in the KIDSCREEN-instrument measuring health related quality of life (HRQoL) in children and adolescents. However, the autonomy questions in KIDSCREEN are restricted to opportunities to influence leisure time activities, which is a form of autonomy as volition. Yet, there are other aspects of autonomy that might be related to adolescent’s HRQoL. The aims of the present study were first to investigate the psychometric properties of a scale measuring autonomy in adolescence from a control perspective (AAC) including its relation to the autonomy dimension in KIDSCREEN, and second; to investigate AACs ability to predict each of the 10 dimensions constituting KIDSCREEN.

Methods
Students (n = 154) aged 15–16 years who were recruited from schools located in both low (two schools) and high (two schools) socioeconomic status (SES) areas in Sweden participated in a cross-sectional study. The adolescents answered a questionnaire including a new 6-item scale measuring perceived autonomy and HRQoL assessed by the KIDSCREEN-52 instrument. A factor analyses was computed to investigate the relation between the items in the AAC scale and the autonomy items in the KIDSCREEN instrument. Hierarchical regression analyses were computed to investigate if the AAC scale predicted HRQoL in any of the 10 dimensions in KIDSCREEN after controlling for gender, SES and the original autonomy scale included in KIDSCREEN.

Results
The factor analysis showed that all the items from the autonomy scale loaded in one factor and that all the items from the AAC scale loaded in another dimension. The hierarchical regression models showed that the AAC scale uniquely predicted HRQoL in all dimensions of the KIDSCREEN instrument after controlling for gender, SES and the original autonomy scale included in KIDSCREEN-52. A high level of perceived autonomy was associated with a high level of HRQoL for both scales.

Conclusion
A new scale for measuring autonomy from a control perspective has been presented and shown to differ from autonomy as volition. Both forms of autonomy are positively related to HRQoL in adolescence 15–16 years old.

Published: September 2022

Abstract
Introduction
The global health crisis caused by the COVID-19 pandemic has had a negative impact on mental health (MH). As a response to the pandemic, international agencies and governmental institutions provided an initial response to the population’s needs. As the pandemic evolved, the population circumstances changed, and some of these international agencies updated their strategies, recommendations, and guidelines for the populations. However, there is currently a lack of information on the attention given to response strategies by the different countries throughout the beginning of the pandemic.

Objectives
1) To evaluate the evolution of online MH strategies and recommendations of selected countries to cope with the MH impact of COVID-19 from the early stages of the pandemic (15 April 2020) to the vaccination period (9 June 2021) and 2) to review and analyse the current structures of these online MH strategies and recommendations.

Methodology
An adaptation of the PRISMA guidelines to review online documents was developed with a questionnaire for MH strategies and recommendations assessment. The search was conducted on Google, including documents from April 2020 to June 2021. Basic statistics and Student’s t test were used to assess the evolution of the documents, while a two-step cluster analysis was performed to assess the organisation and characteristics of the most recent documents.

Results
Statistically significant differences were found both in the number of symptoms and mental disorders and MH strategies and recommendations included in the initial documents and the updated versions generated after vaccines became available. The most recent versions are more complete in all cases. Regarding the forty-six total documents included in the review, the cluster analysis showed a broad distribution from wide-spectrum documents to documents focusing on a specific topic.

Conclusions
Selected governments and related institutions have worked actively on updating their MH online documents, highlighting actions related to bereavement, telehealth and domestic violence. The study supports the use of the adaptation, including the tailor-made questionnaire, of the PRISMA protocol as a potential standard to conduct longitudinal assessments of online documents used to support MH strategies and recommendations.

AbstractBackgroundRecent research has shown the mental health consequence of social distancing during the COVID-19 pandemic, but longitudinal data are relatively scarce. It is unclear whether the pattern of isolation and elevated stress seen at the beginning of the pandemic persists over time. This study evaluates change in social interaction over six months and its impact on emotional wellbeing among older adults.MethodsWe drew data from a panel study with six repeated assessments of social interaction and emotional wellbeing conducted monthly May through October 2020. The sample included a total of 380 White, Black and Hispanic participants aged 50 and over, of whom 33% had low income, who residing in fourteen U.S. states with active stay-at-home orders in May 2020. The analysis examined how change in living arrangement, in-person interaction outside the household, quality of relationship with family and friends, and perceived social support affected trajectories of isolation stress, COVID worry and sadness.ResultsWhile their living arrangements (Odds Ratio [OR] = 0.95, 95% Confidence Interval [CI] = 0.87, 1.03) and relationship quality (OR = 0.94, 95% CI = 0.82, 1.01) remained stable, older adults experienced fluctuations in perceived social support (linear Slope b = -1.42, s.e. = 0.16,p < .001, quadratic slope b = 0.50, s.e. = 0.08,p < .001, cubic slope b = -0.04, s.e. = 0.01,p < .001) and increases in in-person conversations outside the household (OR = 1.19, 95% CI = 1.09, 1.29). Living with a spouse/partner stabilized isolation stress (change in linear slope b = 1.16, s.e. = 0.48,p < .05, in quadratic slope b = -0.62, s.e. = 0.26,p < .05, and in cubic slope = 0.09, s.e. = 0.04,p < .05) and COVID worry (change in quadratic slope b = -0.66, s.e. = 0.32,p < .05 and in cubic slope = 0.09, s.e. = 0.04,p < .05) over time. Individuals with better relationship quality with friends had decreased sadness over time (OR = 0.90, 95% CI = 0.82, 0.99). Changes in social support were associated with greater fluctuations in isolation stress and COVID worry.ConclusionsDuring the pandemic, social interactions are protective and lack of stability in feeling supported makes older adults vulnerable to stress. Efforts should focus on (re)building and maintaining companionship and support to mitigate the pandemic’s negative impact.
