Purpose

Study objectives were to estimate the cumulative incidence of death due to different causes of death (CODs) and investigate the effect of invasive aspergillosis (IA) on each separate COD in a cohort of older patients with acute myeloid leukaemia (AML) or high-risk myelodysplastic syndrome (MDS) included in the Haemato-Oncology Foundation for Adults in the Netherlands (HOVON) 43 randomized controlled trial.

Methods

Pre-collected data from the trial was obtained from the HOVON data center and relevant clinical information was extracted. The cumulative incidence of death due to different CODs was estimated with a competing risk model and the association between each COD and prognostic factors, including IA, were investigated with a cause-specific hazard Cox regression model.

Results

In total 806 patients were included, mean age of 70 years and 55% were male. The cumulative incidences of death due to leukaemia or infection at 3, 6, 12 and 36 months were 0.06, 0.11, 0.23, 0.42 and 0.17, 0.19, 0.22, 0.25 respectively. Incidence of IA was 21% and diagnosis of IA up until the final chemotherapy cycle was associated with an increased risk of dying from leukaemia (cause-specific hazard ratio (CSHR): 1.75, 95% CI 1.34–2.28) and a trend was seen for infection (CSHR: 1.36, 95% CI 0.96–1.91).

Conclusion

Leukaemia was the most likely cause of death over time, however in the first year after diagnosis of AML or high-risk MDS infection was the most likely cause of death. Patients with IA had a relatively increased risk of dying from leukaemia or infection.

Background

Influenza is an acute respiratory infectious disease that is highly infectious and seriously damages human health. Reasonable prediction is of great significance to control the epidemic of influenza.

Methods

Our Influenza data were extracted from Shanxi Provincial Center for Disease Control and Prevention. Seasonal-trend decomposition using Loess (STL) was adopted to analyze the season characteristics of the influenza in Shanxi Province, China, from the 1st week in 2010 to the 52nd week in 2019. To handle the insufficient prediction performance of the seasonal autoregressive integrated moving average (SARIMA) model in predicting the nonlinear parts and the poor accuracy of directly predicting the original sequence, this study established the SARIMA model, the combination model of SARIMA and Long-Short Term Memory neural network (SARIMA-LSTM) and the combination model of SARIMA-LSTM based on Singular spectrum analysis (SSA-SARIMA-LSTM) to make predictions and identify the best model. Additionally, the Mean Squared Error (MSE), Mean Absolute Error (MAE) and Root Mean Squared Error (RMSE) were used to evaluate the performance of the models.

Results

The influenza time series in Shanxi Province from the 1st week in 2010 to the 52nd week in 2019 showed a year-by-year decrease with obvious seasonal characteristics. The peak period of the disease mainly concentrated from the end of the year to the beginning of the next year. The best fitting and prediction performance was the SSA-SARIMA-LSTM model. Compared with the SARIMA model, the MSE, MAE and RMSE of the SSA-SARIMA-LSTM model decreased by 38.12, 17.39 and 21.34%, respectively, in fitting performance; the MSE, MAE and RMSE decreased by 42.41, 18.69 and 24.11%, respectively, in prediction performances. Furthermore, compared with the SARIMA-LSTM model, the MSE, MAE and RMSE of the SSA-SARIMA-LSTM model decreased by 28.26, 14.61 and 15.30%, respectively, in fitting performance; the MSE, MAE and RMSE decreased by 36.99, 7.22 and 20.62%, respectively, in prediction performances.

Conclusions

The fitting and prediction performances of the SSA-SARIMA-LSTM model were better than those of the SARIMA and the SARIMA-LSTM models. Generally speaking, we can apply the SSA-SARIMA-LSTM model to the prediction of influenza, and offer a leg-up for public policy.

Authors: Pan Zhen-zhen , Zhu Miao-juan , Rong Yu-qiong , Yang Jiong
Published: February 2023

Background

Trichinosis is a worldwide food-borne zoonotic parasitic disease, which is mainly obtained by ingesting undercooked meat containing infected larvae. The purpose of our article is to introduce and discuss two rare cases of pleural effusion caused by Trichinella spiralis.

Case presentation

Here we described two male patients who presented to the respiratory department of our hospital with a massive unilateral pleural effusion, their serum eosinophils were in the normal range, laboratory serological tests revealed that Trichinella spiralis IgG antibody was positive. After the oral administration of antiparasitic drugs, the pleural effusion of two patients was completely absorbed.

Conclusion

Both patients were diagnosed with Trichinosis complicated with pleural effusion, which is very rare in the clinic and easy to be misdiagnosed because of normal eosinophils.

Published: February 2023

Background

Glioma is characterized by high morbidity, high mortality, and poor prognosis. Despite tremendous advances in the treatment of glioma, the prognosis of patients with glioma is still unsatisfactory. There is an urgent need to discover novel molecular markers that effectively predict prognosis in patients with glioma. The investigation of the role of WEE2-AS1 in various tumors is an emerging research field, but the biological function and prognostic value of WEE2-AS1 in glioma have rarely been reported. This study aimed to assess the value of WEE2-AS1 as a potential prognostic marker of glioma.

Methods

Gene expression (RNA-Seq) data of patients with glioma were extracted from The Cancer Genome Atlas (TCGA) and the Genotype-Tissue Expression (GTEx) databases. The Wilcoxon rank sum test was used to analyze the expression of WEE2-AS1 in the cells and tissues of glioma. The Kruskal–Wallis rank sum test, Wilcoxon rank sum test, and logistic regression were used to evaluate the relationship between clinical variables and expression of WEE2-AS1. Cox regression analysis and the Kaplan–Meier method were used to evaluate the prognostic factors in glioma. A nomogram based on Cox multivariate analysis was used to predict the impact of WEE2-AS1 on glioma prognosis. Gene Set Enrichment Analysis (GSEA) was used to identify key WEE2-AS1-associated signaling pathways. Spearman’s rank correlation was used to elucidate the association between WEE2-AS1 expression and immune cell infiltration levels.

Results

We found that WEE2-AS1 was overexpressed in a variety of cancers, including glioma. High expression of WEE2-AS1 was associated with glioma progression. We determined that the expression of WEE2-AS1 might be an independent risk factor for the survival and prognosis of patients with glioma. We further observed that the mechanism of WEE2-AS1-mediated tumorigenesis involved neuroactive ligand-receptor interaction, cell cycle, and the infiltration of immune cells into the glioma microenvironment.

Conclusion

These findings demonstrate that WEE2-AS1 is a promising biomarker for the diagnosis and prognosis of patients with glioma. An increased understanding of its effects on the regulation of cell growth may lead to the development of clinical applications that improve the prognostic status of patients with glioma.

Authors: Yoon Kyungwoo , Park Jong Beom , Kang Min Seok , Kim Eung Suk , Yu Seung-Young , Kim Kiyoung
Published: February 2023

Purpose

To evaluate the peripapillary microvasculature changes in patients with epiretinal membrane (ERM) following pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling using swept-source optical coherence tomography angiography (SS-OCTA).

Method

Medical records and multimodal imaging data of 33 eyes after PPV for ERM were retrospectively reviewed. Peripapillary SS-OCTA images of 6×6 mm2 were recorded at at pre- and post-operatively every 6 months for 1 year. A semi-automated method was used to analyzed SS-OCTA images, excluding the optic disc area, using the MATLAB software. The peripapillary vessel density (pVD) of superficial capillary plexus (SCP) and deep capillary plexus (DCP) was quantified in four quadrants (superior, inferior, nasal and temporal).

Result

The mean pVD in SCP and DCP decreased at 6- and 12-months follow-up. In sectoral analysis, superior, inferior, and temporal quadrants pVD in SCP and DCP were significantly reduced at 1 year after vitrectomy (all p < 0.05). Meanwhile, inferior quadrants pVD in SCP and DCP showed the earliest significant reduction at 6-months (p = 0.022 and 0.048, respectively). A reduction of post-operative mean pVD in DCP was significantly greater in patients with diabetic retinopathy (p = 0.043).

Conclusion

Peripapillary capillary density significantly decreased after surgical removal of ERM. Vitrectomy with ILM peeling can cause peripapillary microvascular damage starting in inferior sector.

Published: February 2023

Introduction

Depression and anxiety are the most prevalent mental disorders in the general population and are expected to be the number one global burden of disease by the year 2030. They are also common comorbid conditions for patients with tuberculosis.

Objective

This study aimed to assess the prevalence of symptoms of depression, and anxiety and their associated factors among patients with tuberculosis attending Gondar city health facilities.

Methods

An institution-based cross-sectional study was conducted from September 01 to 30/2020. A census sampling technique was employed to select 390 patients. A structured interviewer-administered questionnaire was used to collect data, and a standardized hospital anxiety and depression scale was used to measure the symptoms of anxiety and depression. Data were entered in Epi-Info version 7 and analyzed using SPSS version 23. Binary and multivariable logistic regressions were computed to identify factors associated with the symptoms of depression and anxiety. P-value < 0.05 and adjusted odds ratios were used to declare the significance and strength of the association.

Results

The overall prevalence of symptoms of depression and anxiety were found to be 35.8% with 95% CI (34.6, 36.6). Perceived stigma and duration of illness > 12 months were associated positively ([AOR = 3.60; 95% CI (2.74, 4.43)], and [AOR = 3.19; 95% CI (2.17, 4.19)]) for both depression and anxiety respectively. Separate analyses revealed that the prevalence of symptoms of depression was 55.9% (95% CI (51.0%, 60.3%) and was significantly associated with duration of illness 4–6 months and > 12 months (AOR = 1.21; 95% CI (1.17, 2.73)] and [AOR = 2.36; 95% CI (2.16, 3.79)], comorbid chronic disease (AOR = 0.12; 95% CI (0.08, 0.91)] and perceived stigma [AOR = 0. The prevalence of anxiety symptoms was 39.5 percent, with 95% confidence intervals of 34.6% and 44.6%, and it was significantly associated with comorbid chronic disease [AOR = 2.53; 95% CI (1.96, 6.32)] and perceived stigma [AOR = 3.31; 95% CI (1.22, 7.74)].

Conclusion

The prevalence of symptoms of depression and anxiety was high. Duration of illness, comorbid chronic disease, and perceived stigma were significantly associated with symptoms of depression. Comorbid chronic disease and perceived stigma were significantly associated with symptoms of anxiety.

Authors: Gomez Katalin Ujhelyi , McBride Orla , Roberts Emmert , Angus Colin , Keyes Katherine , Drummond Colin , Buchan Iain , Fleming Kate , Gilmore Ian , Donoghue Kim , Bonnet Laura , Goodwin Laura
Published: February 2023

Background

There is strong evidence for the co-occurrence of mental health conditions and alcohol problems, yet physical health outcomes among this group are not well characterised. This study aimed to identify clusters of physical health conditions and their associations with mental health and problematic alcohol use in England’s general population.

Methods

Cross-sectional analysis of the 2014 Adult Psychiatric Morbidity Survey (N = 7546) was conducted. The survey used standardised measures of problematic alcohol use and mental health conditions, including the Alcohol Use Disorders Identification Test (AUDIT) and the Clinical Interview Schedule-Revised. Participants self-reported any lifetime physical health conditions. Latent class analysis considered 12 common physical illnesses to identify clusters of multimorbidity. Multinomial logistic regression (adjusting for age, gender, ethnicity, education, and occupational grade) was used to explore associations between mental health, hazardous drinking (AUDIT 8 +), and co-occurring physical illnesses.

Results

Five clusters were identified with statistically distinct and clinically meaningful disease patterns: ‘Physically Healthy’ (76.62%), ‘Emerging Multimorbidity’ (3.12%), ‘Hypertension & Arthritis’ (14.28%), ‘Digestive & Bowel Problems’’ (3.17%), and ‘Complex Multimorbidity’ (2.8%). Having a mental health problem was associated with increased odds of ‘Digestive & Bowel Problems’ (adjusted multinomial odds ratio (AMOR) = 1.58; 95% CI [1.15–2.17]) and ‘Complex Multimorbidity’ (AMOR = 2.02; 95% CI [1.49–2.74]). Individuals with co-occurring mental health conditions and problematic alcohol use also had higher odds of ‘Digestive & Bowel Problems’ (AMOR = 2.64; 95% CI [1.68–4.15]) and ‘Complex Multimorbidity’ (AMOR = 2.62; 95% CI [1.61–4.23]).

Conclusions

Individuals with a mental health condition concurrent with problematic alcohol use experience a greater burden of physical illnesses, highlighting the need for timely treatment which is likely to include better integration of alcohol and mental health services.
Results of the Cologne Corona Surveillance (CoCoS) study – a cross-sectional study: survey data on risk factors of SARS-CoV-2 infection in adults

Published: February 2023

Background

The personal, environmental, and behavioral risk factors that play an important role in the spread of SARS-CoV-2 are still largely unclear. At the same time, there is limited evidence on the effectiveness of specific countermeasures for SARS-CoV-2. As a first approach to these questions, we use data from the Cologne Corona Surveillance (CoCoS) study, a large cross-sectional study conducted in Cologne, Germany, in June 2021.

Methods

This study was conducted in Cologne, Germany. Six thousand randomly selected Cologne residents who were 18 years of age or older were invited to participate in this study. Participant information was obtained via an online survey. Previous SARS-CoV-2 infections were recorded using self-reports. Sociodemographic and environmental information such as age, sex, living situation were collected. Potential SARS-CoV-2 risk behaviors were captured (workplace situation, adherence to hygiene regulations, and regular use of public transportation). Adherence to hygiene regulations was surveyed by determining the compliance with the ‘AHA’-rules (German acronym that stands for keeping a distance of 1.5 m from fellow citizens, hand disinfection, and wearing a face mask). Binary logistic regression analysis was used to identify risk factors for SARS-CoV-2 infection.

Results

A sample of 2,433 study participants provided information. Comparison of the sample with the general population showed representativeness for most sociodemographic characteristics with a preference for higher level of education in the study sample. Younger age, as well as living with minor children (under 18 years) in the same household were associated with a higher number of self-reported SARS-CoV-2 infections. Adherence to hygiene regulations was associated with fewer self-reported SARS-CoV-2 infections in adults. Gender, size of living space per person, workplace situation (work from home versus working with contact to colleagues/customers), and regular use of public transportation showed no significant association with self-reported SARS-CoV-2 infections in multivariable analysis.

Conclusion

The presented results provide initial indications of which sociodemographic and behavioral factors may be associated with SARS-CoV-2 infection. However, the fact that these factors were recorded without exact dates and could have changed accordingly during the pandemic or after infection limits the strength of the results.

Associations between adolescents’ energy drink consumption frequency and several negative health indicators
Authors: Puupponen Maija , Tynjälä Jorma , Välimaa Raili , Paakkari Leena
Published: February 2023

Background

The purpose of this study was to identify how various negative health indicators are associated with energy drink consumption frequency among 13- and 15-year-old Finnish adolescents.

Methods

Data (N = 2429) from the nationally representative international Health Behaviour in School-aged Children study (2018) were analyzed via descriptive analysis and logistic regression analyses, with control for salient covariates. Relative risks (RR) were derived from the adjusted odds ratios.

Results

Even infrequent energy drink consumption was associated with various negative health indicators. Moreover, as compared to non-users, frequent energy drink consumers were more likely to report several health-compromising behaviors: current smoking (RR = 9.85, 95% CI: 5.68–16.02), current snus use (RR = 3.62, 95% CI: 1.80–6.85), cannabis use (RR = 3.42, 95% CI: 1.69–6.52), alcohol consumption (RR = 3.08, 95% CI: 2.49–3.71), problematic social media use (RR = 2.53, 95% CI:1.68–3.72), short sleep (RR = 2.12, 95% CI: 1.69–2.60), skipping breakfast (RR = 1.87, 95% CI: 1.51–2.29), drunkenness (RR = 1.59, 95% CI: 1.11–2.23), inadequate tooth brushing (RR = 1.28, 95% CI: 1.05–1.54). In addition, frequent energy drink consumption was associated with perceived negative health indicators: feelings of insufficient sleep (RR = 1.56, 95% CI: 1.11–2.15), low self-rated health (RR = 1.48, 95% CI: 1.15–1.87), and multiple health complaints (RR = 1.31, 95% CI: 1.07–1.56).

Conclusions

Energy drink consumption, even infrequent, was associated with several negative health indicators, and the reporting of these increased with the frequency of energy drink consumption. The findings support the concerns of health authorities regarding the negative associations between energy drink consumption and health, even among persons as young as 13 years. There is evidence to support specific policy level actions, including restrictions on the sale of energy drinks to adolescents. This measure has been proposed in a Finnish government program, but implementation has yet to occur. Moreover, marketing of these beverages in platforms that are popular among adolescents (e.g., the social media) should be rigorously evaluated, and comprehensive interventions and actions implemented to ensure that adolescents, parents/guardians, and professionals working with adolescents (e.g., in schools) have a good understanding of the links between energy drink consumption and health.
COVID-19 vaccine refusal associated with health literacy: findings from a population-based survey in Korea
Authors: Song Inmyung , Lee Soo Hyun
Published: February 2023

Background:

Poor health literacy is associated with lower utilization of preventable services. However, the relationship between health literacy and COVID-19 vaccine hesitancy remains controvertible.

Methods:

This study used data from 229,242 individuals who completed the Community Health Survey in Korea from August 16 to October 31 in 2021. To operationalize COVID-19 vaccine hesitancy, we measured vaccine refusal, which is defined as not having been vaccinated and not intending to get vaccinated against COVID-19. Health literacy is operationalized in two dimensions; the ability to understand spoken directions from health professionals and the ability to understand written information regarding health. Covariates include sex, age, educational level, marital status, employment status, basic living security pension status, and subjective health status. Two multivariable logistic regression models were run to determine factors associated with COVID-19 vaccine refusal. Model 1 included sociodemographic characteristics and subjective health status. Model 2 added two health literacy variables. Odds ratio (OR) and 95% confidence intervals (CI) were calculated.

Results:

Only 3.9% of the Korean adult population were estimated to refuse COVID-19 vaccine. The most commonly cited reasons for COVID-19 vaccine refusal were concerns about vaccine adverse events (47.6%), followed by the assessment of one’s own health status (29.5%). Individuals who found spoken directions very difficult to understand were more likely to refuse COVID-19 vaccine than those who found spoken directions very easy (OR = 1.55, 95% CI: 1.28–1.87, p < 0.001). People who did not pay attention to written information were more likely to refuse COVID-19 vaccine than those who reported it to be very easy to understand (OR = 1.28, 95% CI: 1.13–1.45, p < 0.001). People in all other categories of the literacy spectrum for either spoken or written information did not have an increased risk of COVID-19 vaccine refusal.

Conclusion:

Health literacy was significantly associated with COVID-19 vaccine refusal. Health literacy programs could be beneficial to reduce vaccine refusal, particularly for the people who find spoken directions from health professionals very difficult to understand and those who do not pay attention to written information.
Cementless augmented versus cemented Dual Mobility cups: medium-term outcome of case series with a control group
Authors: Ebied Ayman , Ebied Ahmed Ali , Badr Ismail Tawfeek , Affara Mostafa , Marie Sameh
Published: February 2023

Background

Post-operative dislocation and reconstruction of acetabular defects are two challenging topics in revision Total Hip Arthroplasty (rTHA). Cemented Dual Mobility (DM) cups on top of Kerboull Cross and bone graft have been successfully employed to overcome these challenges. The cementless augmented DM cups were recently introduced. In this study medium term results of the augmented cementless DM Coptos cups are reported and compared to the established technique of cemented DM cups and Kerboull plate.

Material and methods

This is a retrospective analysis of data collected on patients who received rTHA using DM cups in the period between June 2015 and September 2020. Two groups of patients were identified. The first group received cementless augmented DM-cups (NOVAE® Coptos TH–SERF) (Coptos TH cup group). The second comparable group who had Kerboull ring (KE ring group) and cemented DM cups (NOVAE® STICK). Demographic data, surgical technique, functional and radiological outcome as well as complications during the follow-up visits are reported.

Results

Forty-two patients with a mean age at the time of revision 48.8 ± 13.6 years. 29 patients received Coptos TH DM-cup, while 13 patients had Bone Graft (BG), KE ring and cemented DM cups for acetabular reconstruction. Acetabular defects were Paprosky types IIB and IIC in 31 patients and IIIA and B in 11 patients. The follow-up was 52.8 ± 21 months (mean ± STD); and the mean Harris Hip Score (HHS) at last visit was 91 ± 5. Good stability of all cups was reported. Full integration of the impaction graft was observed in 94% of the Coptos and 92% of the KE groups. One of the Coptos cups was readjusted and one case of single dislocation was recorded in the KE group. None of the DM cups in both groups was revised or awaiting revision.

Conclusion

Coptos TH cups achieve similar results to the cemented DM on KE ring at the medium term but long term outcome remains to be seen.
A case report and literature review of Carney complex with atrial adenomyxoma
Authors: Xu Jing , Ye Meng , Li Po , Xu Shujing , Zhang Miao , Shi Lixin , He Juan
Published: February 2023

Background

Carney complex (CNC) is a rare multiple endocrine neoplasia syndrome characterized by mucocutaneous lentigines/ blue nevi, cardiac myxoma and endocrine overactivity. Here, we report a CNC case with PRKAR1A gene mutation characterized by left atrial adenomyxoma to explore the diagnosis and treatment of CNC.

Case presentation

A 42-year-old woman with a history of cardiac tumour surgery presented with typical features of Cushing syndrome, including central obesity, buffalo hump, mild facial plethora, purple striae on the lower abdomen, and spotty skin pigmentation. Left atrial adenomyxoma and thyroid papillary carcinoma were identified by postoperative histologic assays. Genetic screening revealed a pathogenic germline heterozygous mutation of c.682C > T (p.R228X) in exon 7 of the PRKAR1A gene. The clinical features and normal ACTH levels suggest this patient suffered the ACTH-independent primary pigmented nodular adrenocortical disease (PPNAD) with cyclic hypercortisolism or ACTH-dependent Cushing syndrome.

Conclusion

CNC is uncommon, however, if a patient develops clinical features involving multiple endocrine and non-endocrine tumors, especially Cushing syndrome and cardiac myxoma, CNC should be considered. Genetic analysis is recommended in patients with suspected CNC.
Dentists’ attitudes toward patient-centered care and its predictors: a cross-sectional study in South Korea
Authors: Lee Minjung , Song Youngha , You Myoungsoon , Park Shin-Young , Ihm Jungjoon
Published: February 2023

Background

Patient-centered care (PCC) has been one of medical practice’s most frequently discussed principles. However, attitudes toward PCC among dentists remain underexplored. This study focuses on examining dentists’ patient-centered attitudes and investigating their predictors.

Methods

The Patient–Practitioner Orientation Scale which consists of Sharing and Caring subscales was used to assess patient-centered attitudes. The statistical analysis included 217 dentists from South Korea. Hierarchical linear regression analysis was performed to examine the predictors such as sociodemographic aspects, academic factors, work-related factors, and empathy.

Results

A patient-centered attitude of Caring subscale (M = 4.29, SD = 0.56) emerged, but the provider-centered attitude was higher in Sharing subscale (M = 3.40, SD = 0.48). Work year, academic track, and empathy were associated significantly with an overall caring aspect of patient-centered attitude, while the gender effect remained insignificant. Empathy had a critical and significant impact on the patient-centered attitude.

Conclusions

Efforts to enhance patient-centeredness in Sharing are needed; post-graduate education and transition to a more patient-centered health system are recommended. Moreover, empathy still matters as it was found to be a significant predictor of patient-centered attitudes. The findings of this study support the need for efforts to enhance patient-centered attitudes among dentists, which will help generate discussion on improving the curriculum of post-graduate education and health system reform.
Benefit-risk assessment of traditional Chinese medicine preparations of sinomenine using multicriteria decision analysis (MCDA) for patients with rheumatoid arthritis
Authors: Xiang Gao , Gao Min , Qin Huirong , Shen Xiaolan , Huang Huilian , Hou Xiaoqiang , Feng Zhitao
Published: February 2023

Objective

A multicriteria decision analysis (MCDA) model was used to evaluate the benefits and risks of traditional Chinese medicine preparations of sinomenine alone or in combination with conventional drugs in the treatment of rheumatoid arthritis (RA) and to provide a basis for the rational clinical application of sinomenine.

Methods

A study search was performed using six major databases, and Review Manager 5.3 was used for data analysis. Then, an MCDA model evaluation system was established for the treatment of RA with sinomenine preparations, and the benefit values, risk values, and total benefit-risk values of sinomenine preparations alone or in combination with conventional drugs were calculated using Hiview 3.2 software. Finally, Monte Carlo simulations were performed using Crystal Ball embedded in Excel software to calculate the 95% confidence intervals (95% CI), and the probability of the differences between the 2 drug regimens was determined to optimize the evaluation results.

Results

Forty-four randomized controlled trials (RCTs) were included. Quantitative assessment of the MCDA model showed that the sinomenine preparation alone offered less benefits than when combined with conventional drugs with a benefit difference of 20 (95% CI 3.06, 35.71). However, the risk of the combination was significantly lower with a risk difference of 13(95% CI -10.26, 27.52). The total value of the benefit-risk of sinomenine alone and in combination with conventional drugs was 46 and 53 at 60% and 40% of the benefit-risk ratio of the two dosing regimens, respectively, with a difference of 7 (95% CI -4.26, 22.12). The probability that the comprehensive score of the combined regimen is greater than that of sinomenine alone is 90.1%, and the evaluation was steady.

Conclusion

The benefit-risk of the combined application regimen of sinomenine is greater than that of sinomenine alone.
Allied health workforce development for participant-led services: structures for student placements in the National Disability Insurance Scheme
Authors: Attrill Stacie , Foley Kristen , Gesesew Hailay Abrha , Brebner Chris
Published: February 2023

Background

Health, disability, and community services are increasingly transitioning from government-led to participant-led funding models, which intend to increase choice and control for service users. Allied health practitioners, who provide many frontline services within the resultant marketised environment, must adjust their knowledge and skills to meet participants’ expectations. However, future workforce strategies to address allied health student capabilities to provide these services have received limited attention. This study explored shifting understandings and practices related to allied health student placements during the implementation of a participant-led funding model within the Australian disability sector: the National Disability Insurance Scheme (NDIS).

Methods

Data for this study came from a two-year disability workforce project exploring allied health placements. Service providers, participants, university representatives, disability advocates and students participated in 48 interviews and two focus groups to provide perspectives on allied health workforce and student placements. The findings result from secondary deductive analysis undertaken following project completion that used Gidden’s (1984) Structuration Theory as a conceptual lens to identify structures and actions related to the marketised service environment that influenced how allied health student placements were undertaken.

Results

The findings were organised using two Structuration concepts: knowledgeability, and duality of structure. These described how service providers, supervisors and students understood, legitimised and prioritised placement activities, and how these structures influenced and were influenced by the actions of stakeholders across NDIS settings, contexts and time. Initially, existing placement structures were not compatible with new structures emerging in the disrupted NDIS service environment. However, over time, and responding to new knowledgeability of service providers, supervisors and students, placement structures were identified, monitored and adjusted to reflect perspectives of all stakeholders.

Conclusions

Participant-led funding invoked structural changes in disability service provision that transformed how stakeholders understood placements and the role of students in service provision. Whilst there were new opportunities for placement, tensions were identified in how learning activities can be enacted within a marketised system in which resources are aligned to participant needs, and structures for workforce development and learning activities are less visible. Further conceptualisation of how student learning and workforce development activities can fit with contemporary funding models is necessary to meet participant, service provider and student needs.
The COVID-19 e-lective: using innovation to manage disrupted medical student clinical placements
Authors: Smith Janie Dade , Jones Peter D.
Published: February 2023

Background

The COVID-19 pandemic changed the way we work, spend, live, and learn. The impact was felt in the health sector where hospitals cancelled elective surgery, put on hold outpatient services, and implemented new social distancing procedures and telehealth systems, to enable hospitals to increase bed capacity. For medical students, these factors meant significant disruption to their clinical placements, remote delivery of their education, cessation of international and interstate placements, complicated by significant travel restrictions and border closures. There were concerns that final year students might be unable to graduate that year due to this lack of clinical exposure.

Innovation

As a result of this disruption in late March 2020 we developed an innovative 6 week ‘COVID-19 e-lective’ rotation, consisting of online modules, virtual clinical tutorials and a COVID project totalling the equivalent of 200 h of work.

Results

An evaluation was undertaken that found it to be remarkably successful in meeting the students’ learning needs and alleviating concerns about disrupted placements. It was also conducted during 2021 for all Year 4 students to help expand clinical placement opportunities.

Outcomes

This paper describes the e-lective, its innovations, its challenges, and its evaluation findings, for others to learn from.

Published: February 2023

Background

As more Americans age in place, it is critical to understand care delivery in the home. However, data on the range of home-based services provided by Medicare is limited. We define a taxonomy of clinical care in the home funded through fee-for-service Medicare and methods to identify receipt of those services.

Methods

We analyzed Fee-for-service (FFS) Medicare claims data from a nationally-representative cohort of older adults, the National Health and Aging Trends Study (NHATS), to identify home-based clinical care. We included 6,664 NHATS enrollees age ≥ 70 and living in the community, observed an average of 3 times each on claims-linked NHATS surveys. We examined provider and service type of home-based clinical care to identify a taxonomy of 5 types: home-based medical care (physician, physician assistant, or nurse practitioner visits), home-based podiatry, skilled home health care (SHHC), hospice, and other fee-for-service (FFS) home-based care. We further characterized home-based clinical care by detailed care setting and visit types.

Results

From 2011–2016, 17.8%-20.8% of FFS Medicare beneficiaries age ≥ 70 received Medicare-funded home-based clinical care. SHHC was the most common service (12.8%-16.1%), followed by other FFS home-based care (5.5%-6.5%), home-based medical care (3.2%-3.9%), and hospice (2.6%-3.0%). Examination of the other-FFS home-based care revealed imaging/diagnostics and laboratory testing to be the most common service.

Conclusions

We define a taxonomy of clinical care provided in the home, serving 1 in 5 FFS Medicare beneficiaries. This approach can be used to identify and address research and clinical care gaps in home-based clinical care delivery.
Regulation of community advisory boards during conduct of clinical trials in Uganda: a qualitative study involving stakeholders
Authors: Mijumbi Andrew Ojok , Mugenyi Levicatus , Nanfuka Mastula , Agaba Collins , Ochieng Joseph
Published: February 2023

Background

Community advisory structures such as Community Advisory Boards (CABs) play an important role of helping researchers to better understand the community at each phase of the clinical trial. CABs can be a source of accurate information on the community, its perception of proposed research and may identify factors that make community members vulnerable to the problem under investigation. Although CABs help to build mutually beneficial relationships between the researcher(s) and the communities in which the clinical trial is being implemented, effective engagement would require ethical guidance and regulatory oversight.

The study assessed the stakeholders’ perspectives regarding the regulatory oversight of CABs in Uganda.

Methods

This was an exploratory study employing qualitative methods of data collection and analysis. Key informant interviews (KIIs) with the trial investigators, CAB chairpersons, community liaison officers, regulators and Research Ethics Committee (REC) chairpersons were conducted. A KII guide was designed and utilized during key informant interviews. The guide included questions on role of investigators and CAB members in clinical trials; challenges of community engagement; facilitation of CABs; regulatory oversight of CABs; work relationships between investigators and CABs; and opinions on how community trials should be conducted among others. All interviews were conducted in English.

Qualitative data were transcribed verbatim. A code book was generated based on the transcripts and study objectives. Thematic analysis was used to analyze data and identify themes. Atlas ti was used to support data analysis.

Results

Of the 34 respondents, 35.3% were investigators, 32.3% CAB chairpersons, 23.5% research regulators/REC Chairs and 8.8% community liaison officers. The findings of the study revealed that CABs are appointed by the research institution/researcher, operate under the guidance of the researcher with limited independence. Additionally, the CABs provide voluntary service and lack guidelines or regulatory oversight. Four themes emerged.

Conclusion

The operations and activities of CABs are not regulated by the national regulators or RECs. The regulatory oversight of CABs should be based on contextualized ethical guidelines. Need for additional training in research ethics, community engagement and sensitization on available ethics guidelines for research.
Lower leg reconstruction after resection of a squamous cell carcinoma on necrobiosis lipoidica with a pedicled fibula and an extended anterolateral thigh flap—a case report
Authors: Bota Olimpiu , Meier Friedegund , Garzarolli Marlene , Schaser Klaus-Dieter , Dragu Adrian , Taqatqeh Feras , Fritzsche Hagen
Published: February 2023

Background

Extensive loss of soft tissue and bone due to neoplasia, trauma, or infection in extremities often leads to amputation.

Case presentation

We present the case of a 72-year-old female patient presenting with an extended cutaneous squamous cell carcinoma of the lower leg, developed on top of necrobiosis lipoidica. After achieving the R0 resection, a 26 × 20-cm soft tissue and 15-cm tibial bone defect resulted. The contralateral leg had been lost due to the same disease 18 years before. We achieved a successful reconstruction of the leg using a pedicled fibula transplantation, an extended anterolateral thigh perforator flap, and an internal fixation with plate and screws. Two years after the original surgery, the patient is relapse-free and mobile, with adequate function of the reconstructed foot.

Conclusions

Our case presented a unique combination of pedicled fibula transplantation and free extended ALT perforator flap to reconstruct an extensive defect after resection of a rare cSCC on top of NL. In selected cases, the boundaries of limb salvage can be pushed far beyond the current standards of treatment.
Young and undamaged recombinant albumin alleviates T2DM by improving hepatic glycolysis through EGFR and protecting islet β cells in mice
Authors: Liu Hongyi , Ju Anji , Dong Xuan , Luo Zongrui , Tang Jiaze , Ma Boyuan , Fu Yan , Luo Yongzhang
Published: February 2023

Background

Albumin is the most abundant protein in serum and serves as a transporter of free fatty acids (FFA) in blood vessels. In type 2 diabetes mellitus (T2DM) patients, the reduced serum albumin level is a risk factor for T2DM development and progression, although this conclusion is controversial. Moreover, there is no study on the effects and mechanisms of albumin administration to relieve T2DM. We examined whether the administration of young and undamaged recombinant albumin can alleviate T2DM in mice.

Methods

The serum albumin levels and metabolic phenotypes including fasting blood glucose, glucose tolerance tests, and glucose-stimulated insulin secretion were studied in db/db mice or diet-induced obesity mice treated with saline or young, undamaged, and ultrapure rMSA. Apoptosis assays were performed at tissue and cell levels to determine the function of rMSA on islet β cell protection. Metabolic flux and glucose uptake assays were employed to investigate metabolic changes in saline-treated or rMSA-treated mouse hepatocytes and compared their sensitivity to insulin treatments.

Results

In this study, treatment of T2DM mice with young, undamaged, and ultrapure recombinant mouse serum albumin (rMSA) increased their serum albumin levels, which resulted in a reversal of the disease including reduced fasting blood glucose levels, improved glucose tolerance, increased glucose-stimulated insulin secretion, and alleviated islet atrophy. At the cellular level, rMSA improved glucose uptake and glycolysis in hepatocytes. Mechanistically, rMSA reduced the binding between CAV1 and EGFR to increase EGFR activation leading to PI3K-AKT activation. Furthermore, rMSA extracellularly reduced the rate of fatty acid uptake by islet β-cells, which relieved the accumulation of intracellular ceramide, endoplasmic reticulum stress, and apoptosis. This study provided the first clear demonstration that injections of rMSA can alleviate T2DM in mice.

Conclusion

Our study demonstrates that increasing serum albumin levels can promote glucose homeostasis and protect islet β cells, which alleviates T2DM.
Axial involvement in enthesitis-related arthritis: results from a single-center cohort
Authors: Guo Yanli , Fang Yuying , Zhang Tonghao , Pan Yuting , Wang Panpan , Fan Zhidan , Yu Haiguo
Published: February 2023

Background

Axial involvement in children with enthesitis-related arthritis (ERA) has characteristics that differ from those of peripheral involvement. This study characterized their clinical characteristics and treatment.

Methods

Patients with ERA at the Children’s Hospital of Nanjing Medical University between January 2018 and December 2020 were included. The ERA cohort was divided into two based on the presence or absence of axial joint involvement. Demographic characteristics, clinical features, and treatments were described and compared.

Results

In total, 105 children with ERA were enrolled (axial ERA, n = 57; peripheral ERA, n = 48). The age at disease onset of the axial group tended to be higher (11.93 ± 1.72 vs. 11.09 ± 1.91 years) and the diagnosis delay was bigger in patients with axial ERA (10.26 ± 11.66 months vs. 5.13 ± 7.92 months). The inflammatory marker levels were significantly higher in patients with axial. There were no differences in HLA-B27 positivity between the groups (34 [59.65%] vs. 28 [58.33%], P > 0.05). Hip involvement was more frequent in the axial group (52.63% vs 27.08%; X2 = 7.033). A total of 38 (66.67%) and 10 (20.83%) patients with axial and peripheral ERA, respectively, were treated with biological disease-modifying anti-rheumatic drugs (DMARDs) at diagnosis. The administration of biologics increased gradually in the axial ERA group, peaking at 18 months and decreasing thereafter, whereas that in the peripheral ERA group peaked at 6 months and began to decline thereafter.

Conclusions

Axial ERA is a persistent active disease and requires a more aggressive treatment. Classification and early recognition of axial involvement may help with timely diagnosis and appropriate management.

Published: February 2023

Background

IMP2 and IMP3 are mRNA binding proteins involved in carcinogenesis. We examined a large cohort of ovarian tumors with the aim to assess the value of IMP2 and IMP3 for differential diagnosis, and to assess their prognostic significance.

Methods

Immunohistochemical analyses with antibodies against IMP2 and IMP3 were performed on 554 primary ovarian tumors including 114 high grade serous carcinomas, 100 low grade serous carcinomas, 124 clear cell carcinomas, 54 endometrioid carcinomas, 34 mucinous carcinomas, 75 mucinous borderline tumors, and 41 serous borderline tumors (micropapillary variant). The associations of overall positivity with clinicopathological characteristics were evaluated using the chi-squared test or Fisher’s Exact test.

Results

We found IMP2 expression (in more than 5% of tumor cells) in nearly all cases of all tumor types, so the prognostic meaning could not be analyzed. The positive IMP3 expression (in more than 5% of tumor cells) was most common in mucinous carcinomas (82%) and mucinous borderline tumors (81%), followed by high grade serous (67%) and clear cell carcinomas (67%). The expression was less frequent in endometrioid carcinomas (39%), low grade serous carcinomas (23%), and micropapillary variant of serous borderline tumors (20%). Prognostic significance of IMP3 could be evaluated only in low grade serous carcinomas in the case of relapse-free survival, where negative cases showed better RFS (p = 0.033).

Conclusion

Concerning differential diagnosis our results imply that despite the differences in expression in the different ovarian tumor types, the practical value for diagnostic purposes is limited. Contrary to other solid tumors, we did not find prognostic significance of IMP3 in ovarian cancer, with the exception of RFS in low grade serous carcinomas. However, the high expression of IMP2 and IMP3 could be of predictive value in ovarian carcinomas since IMP proteins are potential therapeutical targets.
