Published: May 2023

Background

Immigrant women’s challenges in realizing sexual and reproductive health and rights (SRHR) are exacerbated by the lack of knowledge regarding how to tailor post-partum contraceptive services to their needs. Therefore, the overall aim of the IMPROVE-it project is to promote equity in SRHR through improvement of contraceptive services with and for immigrant women, and, thus, to strengthen women’s possibility to choose and initiate effective contraceptive methods post-partum.

Methods

This Quality Improvement Collaborative (QIC) on contraceptive services and use will combine a cluster randomized controlled trial (cRCT) with a process evaluation. The cRCT will be conducted at 28 maternal health clinics (MHCs) in Sweden, that are the clusters and unit of randomization, and include women attending regular post-partum visits within 16 weeks post birth. Utilizing the Breakthrough Series Collaborative model, the study’s intervention strategies include learning sessions, action periods, and workshops informed by joint learning, co-design, and evidence-based practices. The primary outcome, women’s choice of an effective contraceptive method within 16 weeks after giving birth, will be measured using the Swedish Pregnancy Register (SPR). Secondary outcomes regarding women’s experiences of contraceptive counselling, use and satisfaction of chosen contraceptive method will be evaluated using questionnaires completed by participating women at enrolment, 6 and 12 months post enrolment. The outcomes including readiness, motivation, competence and confidence will be measured through project documentation and questionnaires. The project’s primary outcome involving women’s choice of contraceptive method will be estimated by using a logistic regression analysis. A multivariate analysis will be performed to control for age, sociodemographic characteristics, and reproductive history. The process evaluation will be conducted using recordings from learning sessions, questionnaires aimed at participating midwives, intervention checklists and project documents.

Discussion

The intervention’s co-design activities will meaningfully include immigrants in implementation research and allow midwives to have a direct, immediate impact on improving patient care. This study will also provide evidence as to what extent, how and why the QIC was effective in post-partum contraceptive services.

Longitudinal mortality of preserved ratio impaired spirometry in a middle-aged Asian cohort
Authors: Sin Sooim , Lee Eun Ju , Won Sungho , Kim Woo Jin
Published: May 2023

Background

Although preserved ratio impaired spirometry (PRISm) has been determined to have poor prognosis, it is a heterogeneous state, and studies regarding its prognosis in Asians are limited. This study investigated the long-term all-cause and cardiovascular mortality of patients with PRISm compared with those of patients with chronic obstructive pulmonary disease (COPD) and normal individuals in the Korean middle-aged general population.

Methods

Participants were recruited between 2001 and 2002 from a community-based prospective cohort in South Korea. Mortality data were collected over a 16.5-year mean follow-up period. The all-cause and cardiovascular mortality risks of PRISm were compared between patients with COPD and healthy controls.

Results

The PRISm group had a mean age of 53.4 years and mean body mass index of 24.9 kg/m2; furthermore, 55.2% of the PRISm patients had never smoked, and the prevalence of comorbidities was not higher than that in the other groups. Compared with normal individuals, PRISm patients did not show increased all-cause mortality, whereas COPD patients showed increased all-cause mortality (PRISm: adjusted hazard ratio [aHR], 1.19; 95% confidence interval [CI], 0.85–1.65; COPD: aHR, 1.34, 95% CI, 1.07–1.69). Furthermore, the PRISm patients did not show increased cardiovascular mortality compared with normal individuals (PRISm: aHR, 1.65; 95% CI, 0.92–2.95; COPD: aHR, 1.83; 95% CI, 1.09–3.07).

Conclusion

In our population-based cohort, all-cause and cardiovascular mortality risk did not increase in individuals with PRISm compared with normal individuals. Further studies are needed to distinguish a lower-risk subgroup of PRISm with certain characteristics, such as middle-aged, light-smoking Asians without additional cardiovascular risk.
CycLing and EducATion (CLEAT): protocol for a single centre randomised controlled trial of a cycling and education intervention versus standard physiotherapy care for the treatment of hip osteoarthritis
Authors: Wainwright Thomas W , Parkinson Erika P , Immins Tikki , Docherty Sharon , Goodwin Elizabeth , Hawton Annie , Low Matthew , Samways Joanna , Rees Tim , Saunders Geoff , Middleton Robert G
Published: May 2023

Background

Osteoarthritis (OA) is a chronic degenerative joint disorder for which there is no known cure. Non-surgical management for people with mild-to-moderate hip OA focuses mainly on alleviating pain and maximising function via the National Institute for Health and Care Excellence (NICE) recommended combination of education and advice, exercise, and, where appropriate, weight loss. The CHAIN (Cycling against Hip pAIN) intervention is a group cycling and education intervention conceived as a way of implementing the NICE guidance.

Methods

CycLing andEducATion (CLEAT) is a pragmatic, two parallel arm, randomised controlled trial comparing CHAIN with standard physiotherapy care for the treatment of mild-to-moderate hip OA. We will recruit 256 participants referred to the local NHS physiotherapy department over a 24-month recruitment period. Participants diagnosed with hip OA according to NICE guidance and meeting the criteria for GP exercise referral will be eligible to participate. Primary outcome is the difference in Hip Disability and Osteoarthritis Outcome Score (HOOS) function, daily living subscale between those receiving CHAIN and standard physiotherapy care. Secondary outcomes include performance-based functional measures (40 m walking, 30s chair stand and stair climb tests), ability for patient to self-care (patient activation measure) and self-reported health-related resource use including primary and secondary care contacts. The primary economic endpoint is the number of quality adjusted life years (QALYs) at 24 weeks follow-up. The study is funded by the National Institute for Health Research, Research for Patient Benefit PB-PG-0816-20033.

Discussion

The literature identifies a lack of high-quality trials which inform on the content and design of education and exercise in the treatment of patients with hip OA and explore cost-effectiveness. CLEAT is a pragmatic trial which seeks to build further evidence of the clinical benefits of the CHAIN intervention compared to standard physiotherapy care within a randomised, controlled trial setting, and examine its cost-effectiveness.

Airway dimensional changes following bone anchored maxillary protraction: a systematic review
Authors: Adel Samar M. , Abbas Bassant A. , Marzouk Wessam W. , Zaher Abbas R.
Published: May 2023

Background

The introduction of skeletal anchorage utilized for maxillary protraction with a face mask or class III elastics has been developed for the management of class III malocclusions with minimal dental effect. The objective of the present review was to evaluate the current evidence regarding airway dimensional changes following bone-anchored maxillary protraction. A search was conducted by two authors (S.A & B.A) in the following databases: MEDLINE via PubMed, Cochrane Library, Web of Science, Scopus, Google Scholar and Open Grey; besides a hand search in references of selected articles and developing a search alert in electronic databases. Selection criteria comprised randomized as well as prospective clinical trials evaluating airway dimensional changes following bone-anchored maxillary protraction. Relevant data were extracted after studies retrieval and selection. The risk of bias was thereafter evaluated using the revised RoB 2 tool for randomized clinical trials and the ROBINS-I tool was used for non-randomized clinical trials. The quality of studies was assessed using the modified Jadad score. After examining (eligibility) full-text articles, four clinical trials were ultimately included. These studies evaluated the airway dimensional changes, following bone-anchored maxillary protraction in comparison to different control study groups. Based on the available evidence, all the bone-anchored maxillary protraction devices used in the eligible studies in the present systematic review resulted in an improvement in the airway dimensions. However, due to the few numbers of studies available and the guarded evidence due to the low quality of evidence of three out of four included articles, there is no strong evidence to support a significant increase in the airway dimensions following bone-anchored maxillary protraction. Therefore, there is a need for more randomized controlled clinical trials with similar bone-anchored protraction devices and similar assessment methods for more valid comparisons, excluding any confounding factors, on airway dimensional changes.
Effectiveness of individualized 3D titanium-printed Orthognathic osteotomy guides and custom plates
Authors: Kim Se-hyang , Lee Sung-Min , Park Jung-Hyun , Yang Sook , Kim Jin-Woo
Published: May 2023

Background

Computer-aided design/manufacturing (CAD/CAM) technology was developed to improve surgical accuracy and minimize errors in surgical planning and orthognathic surgery. However, its accurate implementation during surgery remains a challenge. Hence, we compared the accuracy and stability of conventional orthognathic surgery and the novel modalities, such as virtual simulation and three-dimensional (3D) titanium-printed customized surgical osteotomy guides and plates.

Methods

This prospective study included 12 patients who were willing to undergo orthognathic surgery. The study group consisted of patients who underwent orthognathic two-jaw surgery using 3D-printed patient-specific plates processed by selective laser melting and an osteotomy guide; orthognathic surgery was also performed by the surgeon directly bending the ready-made plate in the control group. Based on the preoperative computed tomography images and intraoral 3D scan data, a 3D virtual surgery plan was implemented in the virtual simulation module, and the surgical guide and bone fixation plate were fabricated. The accuracy and stability were evaluated by comparing the results of the preoperative virtual simulation (T0) to those at 7 days (T1) and 6 months (T2) post-surgery.

Result

The accuracy (ΔT1‒T0) and stability (ΔT2‒T1) measurements, using 11 anatomical references, both demonstrated more accurate results in the study group. The mean difference of accuracy for the study group (0.485 ± 0.280 mm) was significantly lower than in the control group (1.213 ± 0.716 mm) (P < 0.01). The mean operation time (6.83 ± 0.72 h) in the control group was longer than in the study group (5.76 ± 0.43 h) (P < 0.05).

Conclusion

This prospective clinical study demonstrated the accuracy, stability, and effectiveness of using virtual preoperative simulation and patient-customized osteotomy guides and plates for orthognathic surgery.
Uncertainty and probability in neonatal end-of-life decision-making: analysing real-time conversations between healthcare professionals and families of critically ill newborns
Authors: Limacher Regula , Fauchère Jean-Claude , Gubler Deborah , Hendriks Manya Jerina
Published: May 2023

Background

A significant number of critically ill neonates face potentially adverse prognoses and outcomes, with some of them fulfilling the criteria for perinatal palliative care. When counselling parents about the critical health condition of their child, neonatal healthcare professionals require extensive skills and competencies in palliative care and communication. Thus, this study aimed to investigate the communication patterns and contents between neonatal healthcare professionals and parents of neonates with life-limiting or life-threatening conditions regarding options such as life-sustaining treatment and palliative care in the decision-making process.

Methods

A qualitative approach to analysing audio-recorded conversations between neonatal team and parents. Eight critically ill neonates and a total of 16 conversations from two Swiss level III neonatal intensive care units were included.

Results

Three main themes were identified: the weight of uncertainty in diagnosis and prognosis, the decision-making process, and palliative care. Uncertainty was observed to impede the discussion about all options of care, including palliative care. Regarding decision-making, neonatologists oftentimes conveyed to parents that this was a shared endeavour. However, parental preferences were not ascertained in the conversations analysed. In most cases, healthcare professionals were leading the discussion and parents expressed their opinion reactively to the information or options received. Only few couples proactively participated in decision-making. The continuation of therapy was often the preferred course of action of the healthcare team and the option of palliative care was not mentioned. However, once the option for palliative care was raised, the parents’ wishes and needs regarding the end-of-life care of their child were obtained, respected, and implemented by the team.

Conclusion

Although shared decision-making was a familiar concept in Swiss neonatal intensive care units, parental involvement in the decision-making process illustrated a somewhat different and complex picture. Strict adherence to the concept of certainty might impede the process of decision-making, thereby not discussing palliation and missing opportunities to include parental values and preferences.
Persistent HPV infection after conization of cervical intraepithelial neoplasia—— a systematic review and meta-analysis
Authors: Zhang Yueyang , Ni Zhiwen , Wei Ting , Liu Qingsong
Published: May 2023

Objective

To systematically evaluate several factors of persistent human papillomavirus (HPV) infection following conization in patients with cervical intraepithelial neoplasia (CIN).

Methods

PubMed, EMBASE and the Cochrane Library were searched from January 1, 1998 to September 10, 2021. Random-effects models for meta-analyses were used and pooled relative risks with 95% confidence intervals were reported. Literature screening, data extraction, and assessment of the risk of bias in the included studies were conducted independently by two researchers. Data analysis was performed with Stata software, version 12.0.

Results

A total of 28 studies were included in this study. Meta-analysis revealed that surgical margin and residual disease were positively correlated with persistent HPV infection after conization. Compared with patients infected with other types of HPV, CIN patients with HPV 16 had a higher persistent infection rate (OR = 1.967, 95% CI (1.232–3.140), P < 0.05).

Conclusions

CIN patients who are postmenopausal, have positive surgical margins and residual lesions, and are positive for HPV 16 are prone to persistent HPV infection after conization.
Determinants of hyperemesis gravidarum among pregnant women attending antenatal care at public and private hospitals in Bahir Dar City, North-West Ethiopia, 2022: a multicenter unmatched case control study
Authors: Asrade Lakachew , Misikir Daniel , Alemu Hiwotemariam , Belachew Amare , Almaw Hunegnaw
Published: May 2023

Introduction

Hyperemesis gravidarum is a severe form of nausea and vomiting during pregnancy characterized by more than 5% weight loss and ketonuria. Although there are cases in Ethiopia, there is still insufficient information regarding the determinant factors of hyperemesis gravidarum.This finding helps to decrease maternal as well as fetal complications of hyperemesis gravidarum by early identification of pregnant mothers who are at high risk. This study aimed to assess determinants of hyperemesis gravidarum among pregnant women attending antenatal care at public and private hospitals in Bahir Dar, North-West Ethiopia, 2022.

Method

A multicenter, facility-based, unmatched case-control study was conducted on 444 pregnant women (148 cases and 296 controls) from January 1 to May 30. Women with a documented diagnosis of hyperemesis gravidarum on the patient chart were considered as cases, and women who attended antenatal care service without hyperemesis gravidarum were assigned as controls. Cases were selected using a consecutive sampling technique, whereas controls were selected using systematic random sampling technique. Data were collected using an interviewer-administered structured questionnaire. The data were entered into EPI-Data version 3 and exported into SPSS version 23 for analysis. Multivariable logistic regression was performed to identify determinants of hyperemesis gravidarum at a p-value of less than 0.05. An adjusted odds ratio with a 95% confidence interval was used to determine the direction of association.

Results

Living in urban (AOR = 2.717, 95% CI : 1.693,4.502), primigravida (AOR = 6.185, 95% CI: 3.135, 12.202), first& second trimester of pregnancy (AOR = 9.301, 95% CI: 2.877,30.067) & (AOR = 4.785, 95% CI: 1.449,15.805) respectively, family history of hyperemesis gravidarum (AOR = 2.929, 95% CI: 1.268,6.765), helicobacter pylori (AOR = 4.881, 95% CI: 2.053, 11.606) & Depression (AOR = 2.195, 95% CI: 1.004,4.797) were found to be determinants of hyperemesis gravidarum.

Conclusion

Living in an urban area, primigravida woman, being in the first and second trimester, having family history of hyperemesis gravidarum, Helicobacter pylori infection, and having depression were the determinants of hyperemesis gravidarum. Primigravid women, those living in urban areas, and women who have a family history of hyperemesis gravidarum should have psychological support and early treatment initiation if they develop nausea and vomiting during pregnancy. Routing screening for Helicobacter pylori infection and mental health care for a mother with depression at the time of preconception care may decreases hyperemesis gravidarum significantly during pregnancy.

World Health Organization stated that traditional medicine is an important part of health care and countries need to consider integrating it into their primary health care system. Traditional bone setting has a long history in Ethiopia and it enjoys enormous acceptance in the community. However, these methods are raw, there is no standardized training and at the same time, complications are common. Therefore, this research aimed to assess the prevalence of traditional bone setting service utilization and associated factors among people with trauma in Mecha district.

MethodsA Community- based cross-sectional study design was employed from January 15 to February 15, 2021. A total of 836 participants were selected using a simple random sampling technique. Binary and multiple logistic regressions were employed to assess the association between the independent variables with traditional bone setting service utilization.

ResultsThe prevalence of traditional bone setting service utilization was 46.05%. Factors significantly associated with TBS utilization were: Age ≥ 60 years (AOR = 0.13, 95% CI: 0.03- 0.43), rural residence (AOR = 3.63, 95% CI: 1.76 -7.50), occupation (merchant (AOR = 0.21, 95% CI: 0.07 -0.61), and housewife (AOR = 4.12, 95% CI: 1.33 -12.70), type of trauma: dislocation (AOR = 6.40, 95% CI: 3.69–11.10), and strain (AOR = 2.09, 95% CI: 1.05- 4.14)), site of trauma: extremity (AOR = 0.20, 95% CI: 0.11, 0.37), trunk (AOR = 0.08, 95% CI: 0.03–0.22), and shoulder (AOR = 0.20, 95% CI: 0.11–0.37), cause of trauma: fall down and natural deformity (AOR = 9.87, 95% CI: 5.93–16.42) and household annual income greater than > 36,500 (AOR = 2.33, 95% CI: 1.29–4.22).

ConclusionThe prevalence of traditional bone setting practice is high in the study area, despite recent advancements in the practice of orthopedics and trauma in Ethiopia. Since TBS services are more accepted in society, the integration of TBS into the health care delivery system is recommended.
Investigation of the activity of baicalein towards Zika virus
Authors: Sawadpongpan Suteema , Jaratsittisin Janejira , Hitakarun Atitaya , Roytrakul Sittiruk , Wikan Nitwara , Smith Duncan R.
Published: May 2023

Background

Zika virus (ZIKV) is a mosquito transmitted virus spread primarily byAedesspecies mosquitoes that can cause disease in humans, particularly when infection occurs in pregnancy where the virus can have a significant impact on the developing fetus. Despite this, there remains no prophylactic agent or therapeutic treatment for infection. Baicalein is a trihydroxyflavone, that is found in some traditional medicines commonly used in Asia, and has been shown to have several activities including antiviral properties. Importantly, studies have shown baicalein to be safe and well tolerated in humans, increasing its potential utilization.

Methods

This study sought to determine the anti-ZIKV activity of baicalein using a human cell line (A549). Cytotoxicity of baicalein was determined by the MTT assay, and the effect on ZIKV infection determined by treating A549 cells with baicalien at different time points in the infection process. Parameters including level of infection, virus production, viral protein expression and genome copy number were assessed by flow cytometry, plaque assay, western blot and quantitative RT-PCR, respectively.

Results

The results showed that baicalein had a half-maximal cytotoxic concentration (CC50) of > 800 µM, and a half-maximal effective concentration (EC50) of 124.88 µM. Time-of-addition analysis showed that baicalein had an inhibitory effect on ZIKV infection at the adsorption and post-adsorption stages. Moreover, baicalein also exerted a significant viral inactivation activity on ZIKV (as well as on dengue virus and Japanese encephalitis virus) virions.

Conclusion

Baicalein has now been shown to possess anti-ZIKV activity in a human cell line.
Learning collaboration at the primary-secondary care interface: a dual-method study to define design principles for interventions in postgraduate training programmes
Authors: Janssen Marijn , Fluit Cornelia R.M.G. , Lubbers Roel R. , Cornelissen Sylvia A. , de Graaf Jacqueline , Scherpbier Nynke D.
Published: May 2023

Background

Collaboration between primary and secondary care (PSCC) is important to provide patient-centered care. Postgraduate training programmes should provide training to learn PSCC. With a design based research (DBR) approach design principles can be formulated for designing effective interventions in specific contexts. The aim of this study is to determine design principles for interventions aimed to learn PSCC in postgraduate training programmes.

Methods

DBR is characterised by multi-method studies. We started with a literature review on learning collaboration between healthcare professionals from different disciplines within the same profession (intraprofessional) to extract preliminary design principles. These were used to inform and feed group discussions among stakeholders: trainees, supervisors and educationalists in primary and secondary care. Discussions were audiotaped, transcribed and analysed using thematic analysis to formulate design principles.

Results

Eight articles were included in the review. We identified four preliminary principles to consider in the design of interventions: participatory design, work process involvement, personalised education and role models. We conducted three group discussions with in total eighteen participants. We formulated three design principles specific for learning PSCC in postgraduate training programmes: (1) The importance of interaction, being able to engage in a learning dialogue. (2) Facilitate that the learning dialogue concerns collaboration. (3) Create a workplace that facilitates engagement in a learning dialogue. In the last design principle we distinguished five subcategories: intervention emphasises the urge for PSCC and is based on daily practice, the presence of role models, the work context creates time for learning PSCC, learning PSCC is formalised in curricula and the presence of a safe learning environment.

Conclusion

This article describes design principles for interventions in postgraduate training programmes with the aim to learn PSCC. Interaction is key in learning PSCC. This interaction should concern collaborative issues. Furthermore, it is essential to include the workplace in the intervention and make adjacent changes in the workplace when implementing interventions. The knowledge gathered in this study can be used to design interventions for learning PSCC. Evaluation of these interventions is needed to acquire more knowledge and adjust design principles when necessary.
Differences in family caregiver experiences and expectations of end-of-life heart failure care across providers and settings: a systematic literature review
Authors: Valleggi Alessandro , Passino Claudio , Emdin Michele , Murante Anna Maria
Published: May 2023

Heart failure impacts patients’ quality of life and life expectancy and significantly affects the daily behaviours and feelings of family caregivers. At the end-of-life, the burden for family caregivers depends on their emotional and sentimental involvement, as well as social costs.

Objectives: The aim of this work is to determine whether and how family caregivers’ experiences and expectations vary in relation to the places of care and teams involved in heart failure management.

Methods: A systematic literature review was conducted, by screening manuscripts dealing with the experience of Family Care Givers’ (FCGs) of patients with Advanced Heart failure. Methods and results were reported following the PRISMA rules. Papers were searched through three databases (PubMed, Scopus and Web of Science). Seven topics were used to synthetize results by reporting qualitative information and quantitative evidence about the experience of FCGs in places of care and with care teams.

Results: Thirty-one papers, dealing with the experience of 814 FCGs, were selected for this systematic review. Most manuscripts came from the USA (N = 14) and European countries (N = 13) and were based on qualitative methods. The most common care setting and provider profile combination at the end of life was home care (N = 22) and multiprofessional teams (N = 27). Family caregivers experienced “psychological issues” (48.4%), impact of patients’ condition on their life (38,7%) and “worries for the future” (22.6%). Usually, when family caregivers were unprepared for the future, the care setting was the home, and there was a lack of palliative physicians on the team.

Discussion: At the end-of-life, the major needs of chronic patients and their relatives are not health related. And, as we observed, non-health needs can be satisfied by improving some key components of the care management process that could be related to care team and setting of care. Our findings can support the design of new policies and strategies.

Published: May 2023

Background

Chronic pain is a highly prevalent health condition among veterans. Traditional pharmacological interventions present unique challenges for chronic pain management including prescription opioid addiction and overdose. In alignment with the 2016 Comprehensive Addiction and Recovery Act and VA’s Stepped Care Model to meet veterans’ pain management needs, the Offices of Rural Health and Pain Management, Opioid Safety, and Prescription Drug Monitoring Program (PMOP) funded an enterprise-wide initiative to implement a Step 3 integrated tele-pain program: Empower Veterans Program (EVP). EVP provides veterans with chronic pain self-care skills using a whole health driven approach to pain management.

Objectives

The Comprehensive Addiction and Recovery Act prompted the strategic approach to offer non-pharmacological options to meet veterans’ pain management needs. EVP, a 10-week interdisciplinary group medical appointment, leverages Acceptance and Commitment Therapy, Mindful Movement, and Whole Health to provide veterans with chronic pain self-care skills. This evaluation was conducted to describe participant characteristics, graduation, and satisfaction rates; and assess pre-post patient-reported outcomes (PRO) associated with EVP participation.

Methods

A sample of 639 veterans enrolled in EVP between May, 2015 and December, 2017 provided data to conduct descriptive analyses to assess participant demographics, graduation, and satisfaction rates. PRO data were analyzed using a within-participants pre-post design, and linear mixed-effects models were used to examine pre-post changes in PRO.

Results

Of 639 participants, 444 (69.48%) graduated EVP. Participant median program satisfaction rating was 8.41 (Interquartile Range: 8.20–9.20). Results indicate pre-post EVP improvements (Bonferroni-adjusted p < .003) in the three primary pain outcomes (intensity, interference, catastrophizing), and 12 of 17 secondary outcomes, including physical, psychological, health-related quality of life (HRQoL), acceptance, and mindfulness measures.

Discussion

Data suggest that EVP has significant positive outcomes in pain, psychological, physical, HRQoL, acceptance, and mindfulness measures for veterans with chronic pain through non-pharmacological means. Future evaluations of intervention dosing effect and long-term effectiveness of the program is needed.
Use telehealth as needed: telehealth substitutes in-person primary care and associates with the changes in unplanned events and follow-up visits
Authors: Cao Ying , Chen Dandi , Smith Maureen
Published: May 2023

Background

Telehealth rapidly expanded since the outbreak of the COVID-19 pandemic. This study aims to understand how telehealth can substitute in-person services by 1) estimating the changes in non-COVID emergency department (ED) visits, hospitalizations, and care costs among US Medicare beneficiaries by visit modality (telehealth vs. in-person) during the COVID-19 pandemic relative to the previous year; 2) comparing the follow-up time and patterns between telehealth and in-person care.

Methods

A retrospective and longitudinal study design using US Medicare patients 65 years or older from an Accountable Care Organization (ACO). The study period was April-December 2020, and the baseline period was March 2019 – February 2020. The sample included 16,222 patients, 338,872 patient-month records and 134,375 outpatient encounters. Patients were categorized as non-users, telehealth only, in-person care only and users of both types. Outcomes included the number of unplanned events and costs per month at the patient level; number of days until the next visit and whether the next visit happened within 3-, 7-, 14- and 30-days at the encounter level. All analyses were adjusted for patient characteristics and seasonal trends.

Results

Beneficiaries who used only telehealth or in-person care had comparable baseline health conditions but were healthier than those who used both types of services. During the study period, the telehealth only group had significantly fewer ED visits/hospitalizations and lower Medicare payments than the baseline (ED 13.2, 95% CI [11.6, 14.7] vs. 24.6 per 1,000 patients per month and hospitalization 8.1 [6.7, 9.4] vs. 12.7); the in-person only group had significantly fewer ED visits (21.9 [20.3, 23.5] vs. 26.1) and lower Medicare payments, but not hospitalizations; the both-types group had significantly more hospitalizations (23.0 [21.4, 24.6] vs. 17.8). Telehealth was not significantly different from in-person encounters in number of days until the next visit (33.4 vs. 31.2 days) or the probabilities of 3- and 7-day follow-up visits (9.2 vs. 9.3% and 21.8 vs.23.5%).

Conclusions

Patients and providers treated telehealth and in-person visits as substitutes and used either depending on medical needs and availability. Telehealth did not lead to sooner or more follow-up visits than in-person services.
Development of a framework and research impact capture tool for nursing, midwifery, allied health professions, healthcare science, pharmacy and psychology (NMAHPPs)
Authors: Newington Lisa , Wells Mary , Begum Samina , Lavender Andy J. , Markham Sarah , Tracy Oliver , Alexander Caroline M.
Published: May 2023

Background

There is an ambitious target to create a UK clinical academic workforce representing 1% of clinicians from nursing, midwifery, the allied health professions, healthcare science, pharmacy and psychology (NMAHPPs). Understanding and recording the impact that clinical academics make across healthcare services is crucial if we are to grow, value and support this highly skilled workforce group. However, it is currently difficult to systematically record, collate and report the impacts associated with NMAHPP research activity. The aims of this project were to i) develop a framework outlining the impacts that were important for key stakeholder groups, and ii) create and pilot a research impact capture tool to record these impacts.

Methods

The framework was developed from the existing literature. It was refined, remodelled and approved by multidisciplinary stakeholder involvement, including patient and public representatives, healthcare managers and research-active clinicians. The framework was converted into a series of questions to create an electronic research impact capture tool, which was also refined through feedback from these stakeholder groups. The impact capture tool was piloted with research-active clinicians across a large NHS Trust and its associated organisations.

Results

The impact framework contained eight elements: clinical background, research and service improvement activities, research capacity building, research into practice, patients and service users, research dissemination, economics and research funding, and collaborations. Thirty individuals provided data for the research impact capture tool pilot (55% response rate). Respondents reported a range of positive impacts representing all elements of the framework. Importantly, research-activity appeared to be a key driver for recruitment and retention in the sample population.

Conclusions

The impact capture tool is a feasible method of recording the breadth of impacts associated with NMAHPP research activity. We encourage other organisations to collaboratively use and refine our impact capture tool, with the aim of standardising reporting, and facilitating discussions about research activity within clinical appraisal. Pooling and comparing data will also allow comparison between organisations, and assessment of change over time or after implementation of interventions aimed at supporting and increasing research activity.

Background

Alzheimer’s disease (AD) pathology impairs cognitive function. Yet some individuals with high amounts of AD pathology suffer marked memory impairment, while others with the same degree of pathology burden show little impairment. Why is this? One proposed explanation is cognitive reserve i.e., factors that confer resilience against, or compensation for the effects of AD pathology. Deep NREM slow wave sleep (SWS) is recognized to enhance functions of learning and memory in healthy older adults. However, that the quality of NREM SWS (NREM slow wave activity, SWA) represents a novel cognitive reserve factor in older adults with AD pathology, thereby providing compensation against memory dysfunction otherwise caused by high AD pathology burden, remains unknown.

Methods

Here, we tested this hypothesis in cognitively normal older adults (N = 62) by combining 11C-PiB (Pittsburgh compound B) positron emission tomography (PET) scanning for the quantification of β-amyloid (Aβ) with sleep electroencephalography (EEG) recordings to quantify NREM SWA and a hippocampal-dependent face-name learning task.

Results

We demonstrated that NREM SWA significantly moderates the effect of Aβ status on memory function. Specifically, NREM SWA selectively supported superior memory function in individuals suffering high Aβ burden, i.e., those most in need of cognitive reserve (B = 2.694, p = 0.019). In contrast, those without significant Aβ pathological burden, and thus without the same  need for cognitive reserve, did not similarly benefit from the presence of NREM SWA (B = -0.115, p = 0.876). This interaction between NREM SWA and Aβ status predicting memory function was significant after correcting for age, sex, Body Mass Index, gray matter atrophy, and previously identified cognitive reserve factors, such as education and physical activity (p = 0.042).

Conclusions

These findings indicate that NREM SWA is a novel cognitive reserve factor providing resilience against the memory impairment otherwise caused by high AD pathology burden. Furthermore, this cognitive reserve function of NREM SWA remained significant when accounting both for covariates, and factors previously linked to resilience, suggesting that sleep might be an independent cognitive reserve resource. Beyond such mechanistic insights are potential therapeutic implications. Unlike many other cognitive reserve factors (e.g., years of education, prior job complexity), sleep is a modifiable factor. As such, it represents an intervention possibility that may aid the preservation of cognitive function in the face of AD pathology, both present moment and longitudinally.

Background

The interaction between tumor cells and immune or non-immune stromal cells creates a unique tumor microenvironment, which plays an important role in the growth, invasion and metastasis of gastric cancer (GC).

Methods

The candidate genes were selected to construct risk-score by univariate and multivariate Cox regression analysis. Nomograms were constructed by combining clinical pathological factors, and the model performance was evaluated by receiver operating characteristic curve, decision curve analysis, net reclassification improvement and integrated discrimination improvement. The functional enrichment between high-risk group (HRisk) and low-risk group (LRisk) was explored through GO, KEGG, GSVA and ssGSEA. CIBERSORT, quanTIseq and xCell were used to explore the immune cell infiltration between HRisk and LRisk. The relevant EMT scores, macrophage infiltration scores and various metabolic scores were calculated through the “IOBR” package and analyzed visually.

Results

Through univariate and multivariate Cox regression analysis, we obtained the risk-score of fittings six lipid metabolism related genes (LMAGs). Through survival analysis, we found that risk-score has significant prognostic significance and can accurately reflect the metabolic level of patients. The AUCs of the nomogram model incorporating risk-score 1, 3 and 5 years were 0.725, 0.729 and 0.749 respectively. In addition, it was found that the inclusion of risk-score could significantly improve the prediction performance of the model. It was found that the arachidonic acid metabolism and prostaglandin synthesis were up-regulated in HRisk, and more tumor metastasis related markers and immune related pathways were also enriched. Further study found that HRisk had higher immune score and M2 macrophage infiltration. More importantly, the immune checkpoints of tumor associated macrophages involved in tumor antigen recognition disorders increased significantly. We also found that ST6GALNAC3 can promote arachidonic acid metabolism and up-regulate prostaglandin synthesis, increase M2 macrophage infiltration, induce epithelial mesenchymal transformation, and affect the prognosis of patients.

Conclusions

Our research found a novel and powerful LMAGs signature. Six-LMAGs features can effectively evaluate the prognosis of GC patients and reflect the metabolic and immune status. ST6GALNAC3 may be a potential prognostic marker to improve the survival rate and prognostic accuracy of GC patients, and may even be a potential biomarker of GC patients, indicating the response to immunotherapy.
The effects of benralizumab on airway geometry and dynamics in severe eosinophilic asthma: a single-arm study design exploring a functional respiratory imaging approach

Published: May 2023

Background

Severe eosinophilic asthma (SEA) is characterised by elevated blood/sputum eosinophil counts and airway inflammation, which can lead to mucus plug-mediated airway obstruction, increased exacerbation frequency, declines in lung function, and death. Benralizumab targets the alpha-subunit of the interleukin-5 receptor found on eosinophils, leading to rapid and near complete eosinophil depletion. This is expected to result in reduced eosinophilic inflammation, reduced mucus plugging and improved airway patency and airflow distribution.

Methods

BURAN is an interventional, single-arm, open-label, uncontrolled, prospective, multicentre study during which participants will receive three 30 mg subcutaneous doses of benralizumab at 4-week intervals. This study will use functional respiratory imaging (FRI), a novel, quantitative method of assessing patients’ lung structure and function based on detailed, three-dimensional models of the airways, with direct comparison of images taken at Weeks 0 and 13. Patients aged ≥ 18 years with established SEA who may be receiving oral corticosteroids and/or other asthma controller medications, who are inadequately controlled on inhaled corticosteroid-long-acting β2-agonist therapies and who have had ≥ 2 asthma exacerbations in the previous 12 months will be included. The objectives of BURAN are to describe changes in airway geometry and dynamics, measured by specific image-based airway volume and other FRI endpoints, following benralizumab therapy. Outcomes will be evaluated using descriptive statistics. Changes in FRI parameters, mucus plugging scores and central/peripheral ratio will be quantified as mean percent change from baseline (Week 0) to Week 13 (± 5 days) and statistical significance will be evaluated using paired t-tests. Relationships between FRI parameters/mucus plugging scores and conventional lung function measurements at baseline will be assessed with linear regression analyses for associations between outcomes, scatterplots to visualise the relationship, and correlation coefficients (Spearman’s rank and Pearson’s) to quantify the strength of these associations.

Conclusions

The BURAN study will represent one of the first applications of FRI—a novel, non-invasive, highly sensitive method of assessing lung structure, function and health—in the field of biologic respiratory therapies. Findings from this study will increase understanding of cellular-level eosinophil depletion mechanisms and improvements in lung function and asthma control following benralizumab treatment.

Backgroud

The role of epigenetic modifications in tumorigenesis has been widely reported. However, the role and mechanism of H3K4me3 modification in lung adenocarcinoma (LUAD) are rarely reported systematically. We, therefore, sought to analyze the characteristics of LUAD associated with H3K4me3 modification, build an H3K4me3-lncRNAs score model to predict the prognosis of patients with LUAD and clarify the potential value of H3K4me3 in immunotherapy of LUAD.

Methods

We evaluated H3K4me3-lncRNA patterns and H3K4me3-lncRNA scores of 477 LUAD samples based on 53 lncRNAs closely correlated to H3K4me3 regulators and comprehensive analyzed the role of these patterns in tumorigenesis and tumor immunity. Using Gene set variation analysis (GSVA), we systematically evaluated the H3K4me3 level of every sample and deeply analyzed the effect of H3K4me3 on the prognosis of LUAD. In addition, we included two independent immunotherapy cohorts to study the impact of high H3K4me3 score on the prognosis of patients. We also used an independent cohort with 52 matched paraffin specimens of LUAD to verify the impact of high H3K3me3 expression on the prognosis of patients.

Results

We identified three H3K4me3-lncRNA patterns that exhibited specific immune characteristics. Characterized by immunosuppressive and increased TGFβ-mediated epithelial-mesenchymal transition (EMT), patients with high H3K4me3-lncRNA score had a poor overall survival and decreased H3K4me3 score. H3K4me3 score was significantly positively correlated with CD4+T-cell and CD8+T-cell activation, programmed cell death and immune checkpoints (ICs) expression, and was negatively correlated with MYC pathway, TP53 pathway, and cell proliferation. Patients with high H3K4me3 score showed elevated expression of ICs, potentiated CD4 T-cell and CD8 T-cell activation, increased programmed cell death, and suppressed cell proliferation and TGFβ-mediated EMT. Patients with high H3K4me3 score and high expression of CTLA4, ICOS, TIGIT, PDCD1LG2, IDO1, CD274, PDCD1, LAG3, or HAVCR2 had the best survival advantage. Two independent immunotherapy cohorts verified that patients with high H3K4me3 score showed an increased inflamed tumor microenvironment (TME) phenotype and enhanced anti-PD-1/L1 immunotherapy response. Immunohistochemistry (IHC) data from 52 matched paraffin specimens of LUAD confirmed that the protein level of H3K4me3 in tumor was significantly lower than that of paracancerous tissues and H3K4me3 brought significant survival benefits to patients with LUAD.

Conclusions

We build an H3K4me3-lncRNAs score model to predict the prognosis of patients with LUAD. More importantly, this study revealed characteristics of H3K4me3 modification in LUAD and clarified the important potential role of H3K4me3 on tumor immunotherapy and patients’ survival.
