Comparison of functional disabilities, place of death and end-of-life medical expenditures among centenarians and non-centenarians in China: a series of cross-sectional studies
Authors: Li Zhong , Ding Ziqin , Zhao Panpan
Published: June 2023

Background

Long-term and end-of-life (EOL) care for older adults has become a global concern due to extended longevity, which is generally accompanied by increased rates of disability. However, differences in the rates of disability in activities of daily living (ADLs), place of death and medical expenditures during the last year of life between centenarians and non-centenarians in China remain unknown. This study aims to fill this research gap to inform policy efforts for the capacity-building of long-term and EOL care for the oldest-old, especially for centenarians in China.

Methods

Data from 20,228 decedents were derived from the 1998–2018 Chinese Longitudinal Healthy Longevity Survey. Weighted logistic and Tobit regression models were used to estimate differences in the prevalence of functional disability, rate of death in hospitals and EOL medical expenditures by age groups among oldest-old individuals.

Results

Of the 20,228 samples, 12,537 oldest-old individuals were female (weighted, 58.6%, hereafter); 3,767 were octogenarians, 8,260 were nonagenarians, and 8,201 were centenarians. After controlling for other covariates, nonagenarians and centenarians experienced a greater prevalence of full dependence (average marginal differences [95% CI]: 2.7% [0%, 5.3%]; 3.8% [0.3%, 7.9%]) and partial dependence (6.9% [3.4%, 10.3%]; 15.1% [10.5%, 19.8%]) but a smaller prevalence of partial independence (-8.9% [-11.6%, -6.2%]; -16.0% [-19.1%, -12.8%]) in ADLs than octogenarians. Nonagenarians and centenarians were less likely to die in hospitals (–3.0% [–4.7%, –1.2%]; –4.3% [–6.3%, –2.2%]). Additionally, nonagenarians and centenarians reported more medical expenditures during the last year of life than octogenarians with no statistically significant differences.

Conclusion

The oldest-old experienced an increased prevalence of full and partial dependence in ADLs with increasing age and reported a decline in the prevalence of full independence. Compared with octogenarians, nonagenarians and centenarians were less likely to die in hospitals. Therefore, future policy efforts are warranted to optimise the service provision of long-term and EOL care by age patterns for the oldest-old population in China.
Clinical characteristics of Leucine-rich glioma-inactivated protein 1 antibody-mediated autoimmune encephalitis in a 6-year-old girl: case report and literature reviews
Authors: Chen Liqing , Su Tangfeng , Liu Yan
Published: June 2023

Background

Autoimmune encephalitis related to the leucine-rich glioma-inactivated protein 1(LGI1) antibody is the most prevalent in older adults, manifesting as seizures, faciobrachial dystonic seizures (FBDS), cognitive impairment, memory disturbance, hyponatremia and neuropsychiatric disorders. However the data pertaining to children affected by the disease is still limited.

Case presentation and literature reviews

This study presents a detailed report of a 6-year-old Chinese girl who experienced nose aches and faciobrachial dystonic seizures (FBDS). Electrolyte testing revealed that she had hyponatremia and brain MRI showed an abnormality in the left temporal pole. Additionally, anti-LGI1 antibodies were detected in both her serum (1:100) and CSF (1:30). The patient was treated with immunotherapy and symptom management, which proved effective. Furthermore, we provide a summary of 25 pediatric cases of anti-LGI1 encephalitis. Pediatric patients rarely exhibited FBDS and hyponatremia, and some cases presented with isolated syndromes. But the therapeutic outcomes of pediatric patients were generally good.

Conclusions

In this report, we describe a patient who developed a rare symptom of nose aches possibly as one of symptoms of anti-LGI1 encephalitis, which highlights the possibility of atypical symptoms in children that may be misdiagnosed. Reviewing the literature, the clinical features differed between pediatric and adult cases. Therefore, it is crucial to collect and analyze data from more cases to promote accurate diagnosis and timely treatment.
Persistence to extended adjuvant endocrine therapy following Breast Cancer Index (BCI) testing in women with early-stage hormone receptor-positive (HR +) breast cancer
Authors: Foldi Julia , Tsagianni Anastasia , Salganik Max , Schnabel Catherine A. , Brufsky Adam , van Londen G. J. , Pusztai Lajos , Sanft Tara
Published: June 2023

Purpose

Extending adjuvant endocrine therapy (ET) beyond the standard 5 years offers added protection against late breast cancer recurrences in women with early-stage hormone receptor-positive (HR +) breast cancer. Little is known about treatment persistence to extended ET (EET) and the role that genomic assays may play. In this study, we evaluated persistence to EET in women who had Breast Cancer Index (BCI) testing.

Methods

Women with stage I-III HR + breast cancer who had BCI testing after at least 3.5 years of adjuvant ET and ≥ 7 years of follow-up after diagnosis were included (n = 240). Data on medication persistence was based on prescriptions in the electronic health record.

Results

BCI predicted 146 (61%) patients to have low – BCI (H/I)-low – and 94 (39%) patients to have high likelihood of benefit from EET (BCI (H/I)-high). Continuation of ET after BCI occurred in 76 (81%) (H/I)-high and 39 (27%) (H/I)-low patients. Non-persistence rates were 19% in the (H/I)-high and 38% in the (H/I)-low group. The most common reason for non-persistence was intolerable side effects. Patients on EET underwent more DXA bone density scans than those who stopped ET at 5 years (mean 2.09 versus 1.27; p < 0.001). At a median follow-up of 10 years from diagnosis, there were 6 metastatic recurrences.

Conclusions

In patients who continued ET after BCI testing, the rates of persistence to EET were high, particularly in patients with predicted high likelihood of benefit from EET. Use of EET is associated with increased use of DXA scans.
Early onset frontotemporal dementia following cannabis abuse: a case report
Authors: Moshfeghinia Reza , Oji Bahare , Hosseinzadeh Mehrnaz , Pourfridoni Mohammad , Ahmadi Jamshid
Published: June 2023

Background

Frontotemporal disorders (FTD) are the consequence of impairment to neurons in the frontal and temporal lobes of the brain. Also, no definitive treatment has been found for FTD. Cannabinoid products can be used to manage treatment-resistant behavioral variants of Frontotemporal dementia (bvFTD).

Case presentation

We describe the case of 34 years old male with two years of marijuana abuse. At first, he presented with symptoms of apathy and bizarre behavior, which became more severe, and led to disinhibition. The clinical symptoms and imaging findings made FTD probable for him, which was very interesting to report.

Conclusions

While cannabis has demonstrated potential in managing behavioral and mental symptoms of dementia, the presented case highlights the profound impact of cannabis consumption on brain structure and chemistry, including the potential for neurodegenerative disorders like FTD.
A review of reviews exploring patient and public involvement in population health research and development of tools containing best practice guidance
Authors: Vinnicombe Soo , Bianchim Mayara S. , Noyes Jane
Published: June 2023

Introduction

Patient and public involvement (PPI) is increasingly seen as something that is integral to research and of importance to research funders. There is general recognition that PPI is the right thing to do for both moral and practical reasons. The aim of this review of reviews is to examine how PPI can be done ‘properly’ by looking at the evidence that exists from published reviews and assessing it against the UK Standards for Public Involvement in Research, as well as examining the specific features of population health research that can make PPI more challenging.

Methods

A review of reviews and development of best practice guidance was carried out following the 5-stage Framework Synthesis method.

Results

In total 31 reviews were included. There is a lack of current research or clarity around Governance and Impact when findings are mapped against UK Standards for Public Involvement in Research. It was also clear that there is little knowledge around PPI with under-represented groups. There are gaps in knowledge about how to ensure key specific attributes of population health research are addressed for PPI team members – particularly around how to deal with complexity and the data-driven nature of the research. Four tools were produced for researchers and PPI members to further improve their PPI activity within population health research and health research more generally, including a framework of recommended actions to address PPI in population health research, and guidance on integrating PPI based on the UK Standards for Public Involvement in Research.

Conclusions

Facilitating PPI in population health research is challenging due to the nature of this type of research and there is far less evidence on how to do PPI well in this context. The tools can help researchers identify key aspects of PPI that can be integrated when designing PPI within projects. Findings also highlight specific areas where more research or discussion is needed.

Published: June 2023

Background

When individuals in the SGM group are diagnosed with cancer and undergo treatment, they experience changes in physical, mental, sexual and spiritual dimensions, which can negatively impact sexual desire, as well as satisfaction and sexual health as a whole. This study aims to examine the existing scientific literature on how healthcare professionals approach sexuality in cancer patients who belong to the SGM group. The SGM group is particularly vulnerable, and the challenges they face in terms of psychosocial and emotional health are further exacerbated by the oncological treatment they receive. Therefore, specialized attention and support are necessary to address their unique needs.

Method

To conduct this study, a scoping review was performed following the guidelines established by the Joanna Briggs Institute. By synthesizing the available evidence, this study aims to provide insights and recommendations for healthcare professionals to improve the care and support provided to SGM individuals with cancer. Guiding question: “how do health professionals approach sexuality in cancer patients in a minority group?”. The search was carried out in PubMed, Science Direct, Scopus, Web of Science, Virtual Health Library, Embase databases and Google Scholar in addition. Specific criteria were used for Evidence source selection, Data mapping, assurance, analysis, and presentation.

Results

Fourteen publications were included in this review for the final synthesis, which indicated that the approach to the sexuality of sexual and gender minority groups is based on research whose character is limited in terms of producing care and health care that is congruent in gender and sexuality. The analysis of scientific articles showed that one of the biggest challenges and priorities of health services today is to reduce disparities and promote equity in health for SGM people.

Conclusions

This study reveals a significant gap in addressing the sexuality of SGM groups within cancer care. Inadequate research impedes the provision of consistent and inclusive care for SGM individuals, which has a negative impact on their overall wellbeing. Reducing disparities and promoting healthcare equity for SGM individuals must be a top priority for health services.
Zero-P and ROI-C implants versus traditional titanium plate with cage to treat cervical spondylotic myelopathy: clinical and radiological results with 5 years of follow-up
Authors: Wang Zhidong , Zhu Xu , Wang Zhenheng , Zhu Ruofu , Chen Guangdong , Gao Maofeng , Chen Kangwu , Yang Huilin
Published: June 2023

Background

Anterior cervical discectomy and fusion (ACDF) is the gold standard for treating cervical spondylotic myelopathy (CSM). While implanting plates in ACDF may increase the risk of complications. Zero-P and ROI-C implants have been gradually applied for CSM.

Methods

150 patients with CSM were retrospectively analyzed from January 2013 to July 2016. Group A consisted of 56 patients who received traditional titanium plates with cage. 94 patients underwent ACDF using zero-profile implants and were divided into 50 patients with the Zero-P device (Group B) and 44 with the ROI-C device (Group C). Related indicators were measured and compared. The clinical outcomes were evaluated by JOA, VAS, and NDI scores.

Results

Compared with group A, group B and C had a less blood loss and shorter operation time. The JOA and VAS scores improved significantly from pre-operative to 3 months postoperative and last follow-up in three groups. The cervical physiological curvature and segmental lordosis at final follow-up were higher than that of pre-operation (p < 0.05). Dysphagia rate, adjacent level degeneration rate, and Osteophyma rate was the highest in group A (p < 0.05). The bone graft fusion was achieved at the final follow-up in three groups. There were no statistical significance in fusion rate and subsidence rate among the three groups.

Conclusions

ACDF with Zero-P or ROI-C implants can also obtain satisfactory clinical outcomes compared to traditional titanium plate with cage after 5 years follow-up. The zero-profile implant devices carry a simple operation, short operation time, less intraoperation blood loss, and incidence of dysphagia.

Authors: Gu Juan , Sun Qingqing , Qi Yujuan , Hu Fangfang , Cao Yijuan
Published: June 2023

Purpose

This paper was mainly conducted to investigate the effect of chronic endometritis (CE) on the clinical outcome of patients with unexplained infertility.

Materials and methods

145 patients with unexplained infertility from the Reproductive Center of our hospital from January 2018 to December 2021 were selected as the unexplained infertility group. 42 patients with definite infertility causes were selected as the control group during the same period. Both groups of patients underwent hysteroscopy and immunohistochemical tests for CD38 and CD138. According to the results of hysteroscopy and immunohistochemistry, the incidence of CE between the two groups was analyzed. Patients with CE as CE group accepted oral antibiotic therapy for 14 days. Another 58 patients with unexplained infertility who did not undergo hysteroscopy and immunohistochemical tests for CD38 and CD138 were selected as the unexamined group. Both groups of patients were expected natural pregnancy. Follow-up lasted for 1 year, and the pregnant patients were followed up until delivery.The clinical pregnancy rate, spontaneous abortion rate and baby-carrying home rate of the two groups were compared.

Results

There were 75 patients with CE in the unexplained infertility group, and the prevalence rate was 51.7% (75/145). Compared with the control group (28.6%), the incidence of CE was significantly higher (P < 0.05). After treated with antibiotic treatment, the patients’ clinical pregnancy rate was 61.3% (46/75) and baby-carrying home rate was 60% (45/75) in the CE group, which were higher than those in the unexamined group(43.1% & 36.2%) (P < 0.05), while the spontaneous abortion rate was 2.2% (1/46),which was lower than that in the unexamined group (16.0%) (P < 0.05).

Conclusions

For patients with unexplained infertility, hysteroscopy combined with endometrial immunohistochemical detection of CD38 and CD138 should be performed in time to exclude CE. The clinical pregnancy outcome of CE patients can be significantly improved by antibiotic treatment.

Authors: Ouoba Kampadilemba , Lehmann Hélène , Zongo Arsène , Semdé Rasmané , Pabst Jean-Yves
Published: June 2023

Background

Traditional health practitioners constitute an important part of the health care system in Burkina Faso, particularly in the supply of traditional herbal medicines. Quality and safety of these medicines rely heavily on practices employed during their traditional development. However, traditional phytopharmaceutical practices are poorly described in Burkina Faso. This study aimed to describe the phytopharmaceutical practices of traditional medicine practitioners in Burkina Faso.

Methods

This was a cross-sectional descriptive ethno-pharmaceutical study, conducted from October 1 to November 30, 2020, among traditional practitioners in four randomly selected health districts: Nongr-Massom (Centre region), Tenkodogo (Centre-East region), Diapaga (East region) and Dafra (Hauts-Bassins region). An anonymous semi-structured face-to-face questionnaire was used to collect socio-demographic data and data on raw materials and finished products.

Results

Sixty-seven (67) traditional health practitioners, aged 56 years on average, including a majority of men (72%), participated in the study. Gathering of wild medicinal plants was the main source of raw materials acquisition (51.5%), which were usually leaves (32.3%). These raw materials were usually sun-dried (43.9%) and packaged mostly in plastic bags (37.2%). They were derived from 60 plant species belonging to 33 botanical families. Fabaceae was the most represented family (18.7%) and Khaya senegalensis Juss. (Meliaceae) the most cited plant species (5.2%). The finished products had an average shelf life of 17 months and were usually prepared as a decoction (31.7%) and administered most often orally (71.4%). Gastrointestinal disorders were the main predictable adverse events of the finished products (54%).

Conclusion

This study showed that THPs have important knowledge in the use of medicinal plants, but several shortcomings are observed in their phytopharmaceutical and plant protection practices. Continuous improvement of these practices, through education and training of traditional health practitioners, is essential for the conservation of plant biodiversity and quality assurance of traditional herbal medicines.

Published: June 2023

Background

Despite concern about migrant children’s mental health and their access to mental healthcare services during the COVID-19 pandemic, this topic has attracted little research attention. This study aimed to examine the impact of the COVID-19 pandemic on the use primary and specialist healthcare services for mental health problems among children and adolescents with migrant background.

Methods

Using event study models, we investigated the impact of lockdown and subsequent COVID-19 infection control measures on children’s health service use for mental health problems according to migrant background. Drawing on reimbursement data from Norwegian public healthcare providers we observe consultations in a pre-pandemic (2017–2019) and pandemic cohort (2019–2021) in primary and specialised care.

Results

The pre-pandemic cohort included 77 324 migrants, 78 406 descendants of migrants and 746 917 non-migrants and the pandemic cohort included 76 830 migrants, 88 331 descendants and 732 609 non-migrants (age 6–19). The full cohorts were observed for mental healthcare use in primary care while a subsample (age 6–16) was observed for health care use in specialist care. Lockdown resulted in a dip in consultation volumes for mental disorders for all children, but this dip was relatively larger and more persistent for children with migrant background. After lockdown, consultation volumes rose more for non-migrant children than for children with migrant background. Consultations in primary healthcare peaked during January to April 2021 for non-migrants and descendants of migrants, but not for migrants (4%, 95% CI -4 to 11). In specialist care during the same period, consultations dropped by 11% for migrants (95% CI -21 to -1).

By October 2021, all mental health consultations in specialist care were up with 8% for non-migrants (95% CI 0 to 15), and down with -18% for migrants and -2% for descendants (95% CIs -31 to -5 and -14 to 10).

Migrant males experienced the largest reduction in consultations.

Conclusions

Changes in consultation volumes among children with migrant background after lockdown were not as pronounced as for non-migrants, and at times actually decreased. This suggests that an increase in barriers to care emerged during the pandemic for children with a migrant background.

Published: June 2023

The objective of this study was to synthesize and characterize pharmaceutical characteristics of florfenicol sustained-release granules (FSRGs) in vitro and in vivo. FSRGs were synthesized using monostearate, polyethylene glycol 4000 and starch. In vitro dissolution profiles were studied using the rotating basket method in pH 1.2 HCl solution and pH 4.3 acetate buffer. Twenty-four male healthy Landrace×Yorkshire pigs were equally divided into three groups and administered a 20 mg/kg i.v bolus of florfenicol solution and dosed orally with FSRGs in the fasting and fed states. The Higuchi model was the best fit for the drug release profile in pH 1.2 and pH 4.3 media, and the mechanism of drug dissolution was governed by both diffusion and dissolution. We established a level A in vitro - in vivo correlation for FSRGs and the in vivo profile of the FSRGs can be estimated by the in vitro drug release.

Published: June 2023

Parkinson’s disease (PD) is characterized by the degeneration of dopaminergic nigrostriatal neurons, which causes disabling motor disorders. Scientific findings support the role of epigenetics mechanism in the development and progression of many neurodegenerative diseases, including PD. In this field, some studies highlighted an upregulation of Enhancer of zeste homolog 2 (EZH2) in the brains of PD patients, indicating the possible pathogenic role of this methyltransferase in PD. The aim of this study was to evaluate the neuroprotective effects of GSK-343, an EZH2 inhibitor, in an in vivo model of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced dopaminergic degeneration. Specifically, nigrostriatal degeneration was induced by MPTP intraperitoneal injection. GSK-343 was administered intraperitoneally daily at doses of 1 mg/kg, 5 mg/kg and 10 mg/kg, mice were killed 7 days after MPTP injection. Our results demonstrated that GSK-343 treatment significantly improved behavioral deficits and reduced the alteration of PD hallmarks. Furthermore, GSK-343 administration significantly attenuated the neuroinflammatory state through the modulation of canonical and non-canonical NF-κB/IκBα pathway as well as the cytokines expression and glia activation, also reducing the apoptosis process. In conclusion, the obtained results provide further evidence that epigenetic mechanisms play a pathogenic role in PD demonstrating that the inhibition of EZH2, mediated by GSK-343, could be considered a valuable pharmacological strategy for PD.

Published: June 2023

Purpose

This study aims to compare results after open lunate excision alone and in combination with palmaris longus tendon ball arthroplasty for the treatment of late-staged Kienböck’s disease (KD).

Methods

This is a retrospective study using the prospectively collected data, and patients who had a discharge diagnosis of KD (stage IIIB based on Lichtman staging criteria) and underwent surgical treatment by lunate excision alone or in combination with palmaris longus tendon ball arthroplasty between January 2011 and December 2020 were included in this study. Variables of interest involved demographics, disease condition, operative procedure, and the outcomes evaluated at the last follow-up. Within and between comparisons were performed.

Results

Thirty-five patients underwent lunate excision alone, and 40 patients underwent the combination procedure. At the final follow-up, patients in both groups exhibited significant improvements compared to pre-operation, such as wrist flexion, wrist extension, carpal height ratio, PRWE score, Cooney score, and grip strength (all P < 0.05). Compared to the excision group, combination procedure group had significantly longer surgical time (P < 0.001), more blood loss (P < 0.001) and exhibited better wrist flexion (P = 0.001), PRWE score (P = 0.001), Cooney score (P = 0.0034), and grip strength (P = 0.017). The excellent or good rate based on Cooney wrist score was not significantly different (87.5% vs 71.4%, P = 0.083).

Conclusion

Lunate excision in combination with palmaris longus tendon ball arthroplasty is a better option than lunate excision alone for the treatment of stage III KD and can be considered as an operative option.
Exploring navigation of gender in a sample of clinically referred young people attending the gender identity development service
Authors: Haywood Daisy , de Andrés María , Masic Una , Carmichael Polly
Published: June 2023

Background

Gender-diverse young people experience a cisnormative world and are subject to unique minority stressors, which have been found to contribute to adverse mental health. This research aims to understand the social and personal context unique to gender-diverse people that young people navigate prior to attending specialised services.

Methods

The baseline measure of a newly developed questionnaire, the GIDS Gender Questionnaire (GIDS-GQ), was sent to all young people (or caregivers for those aged under 12) attending the Gender Identity Development Service (GIDS). Eighty-four young people and caregivers completed the questionnaire, with eighty-one included in the final sample (M = 15.77 years, SD = 1.83, range = 9–17; assigned female at birth = 72, assigned male at birth = 9). Questionnaires were emailed to participants via an online survey between one and three appointments with the Service. Data were collected between April 2021 and February 2022.

Results

All young people had initiated a social transition, with 75.3% categorised as fully socially transitioned. More young people reported experiencing transphobic bullying (64.2%) and a lack of acceptance of their gender identity (85.1%) in the past (lifetime) than in the 6 months prior to attending the service (transphobic bullying: 12.3%; non-acceptance: 49.4%). 94.5% of the sample reported disliked body parts, most commonly breasts (80.8%), genitals (37%), and hips (31.5%). Participants most commonly reported a decrease in their mood (61.25%) and most areas of social connectedness.

Conclusions

The majority of this sample had socially transitioned, were supported in their identification, and had experienced less transphobic bullying and non-acceptance prior to commencing services. However, young people continued to dislike their bodies, and experience low mood and social connectedness. Future research is needed to understand how clinical support can help reduce the impact of these external/distal minority stressors by promoting social connectedness, incorporating such learnings into clinical practice and subsequent policy in clinical work with gender-diverse young people.

Published: June 2023

Background

There are few prospective studies on the correlations between MRI features and whole RNA-sequencing data in breast cancer according to molecular subtypes. The purpose of our study was to explore the association between genetic profiles and MRI phenotypes of breast cancer and to identify imaging markers that influences the prognosis and treatment according to subtypes.

Methods

From June 2017 to August 2018, MRIs of 95 women with invasive breast cancer were prospectively analyzed, using the breast imaging-reporting and data system and texture analysis. Whole RNA obtained from surgical specimens was analyzed using next-generation sequencing. The association between MRI features and gene expression profiles was analyzed in the entire tumor and subtypes. Gene networks, enriched functions, and canonical pathways were analyzed using Ingenuity Pathway Analysis. The P value for differential expression was obtained using a parametric F test comparing nested linear models and adjusted for multiple testing by reporting Q value.

Results

In 95 participants (mean age, 53 years ± 11 [standard deviation]), mass lesion type was associated with upregulation of CCL3L1 (sevenfold) and irregular mass shape was associated with downregulation of MIR421 (sixfold). In estrogen receptor-positive cancer with mass lesion type, CCL3L1 (21-fold), SNHG12 (11-fold), and MIR206 (sevenfold) were upregulated, and MIR597 (265-fold), MIR126 (12-fold), and SOX17 (fivefold) were downregulated. In triple-negative breast cancer with increased standard deviation of texture analysis on precontrast T1-weighted imaging, CLEC3A (23-fold), SRGN (13-fold), HSPG2 (sevenfold), KMT2D (fivefold), and VMP1 (fivefold) were upregulated, and IGLC2 (73-fold) and PRDX4 (sevenfold) were downregulated (all, P < 0.05 and Q < 0.1). Gene network and functional analysis showed that mass type estrogen receptor-positive cancers were associated with cell growth, anti-estrogen resistance, and poor survival.

Conclusion

MRI characteristics are associated with the different expressions of genes related to metastasis, anti-drug resistance, and prognosis, depending on the molecular subtypes of breast cancer.
Meta-research on pragmatism of randomized trials: rationale and design of the PragMeta database
Authors: Hirt Julian , Janiaud Perrine , Düblin Pascal , Hemkens Lars G.
Published: June 2023

Background

Pragmatic trials provide decision-oriented, real-world evidence that is highly applicable and generalizable. The interest in real-world evidence is fueled by the assumption that effects in the “real-world” are different to effects obtained under artificial, controlled, research conditions as often used for traditional explanatory trials. However, it is unknown which features of pragmatism, generalizability, and applicability would be responsible for such differences. There is a need to provide empirical evidence and promote meta-research to answer these fundamental questions on the pragmatism of randomized trials and real-world evidence. Here, we describe the rationale and design of the PragMeta database which pursues this goal (www.PragMeta.org).

Methods

PragMeta is a non-commercial, open data platform and infrastructure to facilitate research on pragmatic trials. It collects and shares data from published randomized trials that either have a specific design feature or other characteristic related to pragmatism or they form clusters of trials addressing the same research question but having different aspects of pragmatism. This lays the foundation to determine the relationship of various features of pragmatism, generalizability, and applicability with intervention effects or other trial characteristics.

The database contains trial data actively collected for PragMeta but also allows to import and link existing datasets of trials collected for other purposes, forming a large-scale meta-database. PragMeta captures data on (1) trial and design characteristics (e.g., sample size, population, intervention/comparison, outcome, longitudinal structure, blinding), (2) effects estimates, and (3) various determinants of pragmatism (e.g., the use of routinely collected data) and ratings from established tools used to determine pragmatism (e.g., the PRagmatic–Explanatory Continuum Indicator Summary 2; PRECIS-2).

PragMeta is continuously provided online, inviting the meta-research community to collaborate, contribute, and/or use the database. As of April 2023, PragMeta contains data from > 700 trials, mostly with assessments on pragmatism.

Conclusions

PragMeta will inform a better understanding of pragmatism and the generation and interpretation of real-world evidence.
Autism-associated gene shank3 is necessary for social contagion in zebrafish
Authors: Kareklas Kyriacos , Teles Magda C. , Dreosti Elena , Oliveira Rui F.
Published: June 2023

Background

Animal models enable targeting autism-associated genes, such as theshank3gene, to assess their impact on behavioural phenotypes. However, this is often limited to simple behaviours relevant for social interaction. Social contagion is a complex phenotype forming the basis of human empathic behaviour and involves attention to the behaviour of others for recognizing and sharing their emotional or affective state. Thus, it is a form of social communication, which constitutes the most common developmental impairment across autism spectrum disorders (ASD).

Methods

Here we describe the development of a zebrafish model that identifies the neurocognitive mechanisms by whichshank3mutation drives deficits in social contagion. We used a CRISPR-Cas9 technique to generate mutations to theshank3agene, a zebrafish paralogue found to present greater orthology and functional conservation relative to the human gene. Mutants were first compared to wild types during a two-phase protocol that involves the observation of two conflicting states, distress and neutral, and the later recall and discrimination of others when no longer presenting such differences. Then, the whole-brain expression of different neuroplasticity markers was compared between genotypes and their contribution to cluster-specific phenotypic variation was assessed.

Results

Theshank3mutation markedly reduced social contagion via deficits in attention contributing to difficulties in recognising affective states. Also, the mutation changed the expression of neuronal plasticity genes. However, only downregulated neuroligins clustered withshank3aexpression under a combined synaptogenesis component that contributed specifically to variation in attention.

Limitations

While zebrafish are extremely useful in identifying the role ofshank3mutations to composite social behaviour, they are unlikely to represent the full complexity of socio-cognitive and communication deficits presented by human ASD pathology. Moreover, zebrafish cannot represent the scaling up of these deficits to higher-order empathic and prosocial phenotypes seen in humans.

Conclusions

We demonstrate a causal link between the zebrafish orthologue of an ASD-associated gene and the attentional control of affect recognition and consequent social contagion. This models autistic affect-communication pathology in zebrafish and reveals a genetic attention-deficit mechanism, addressing the ongoing debate for such mechanisms accounting for emotion recognition difficulties in autistic individuals.
Interleukin-22 facilitates the interferon-λ-mediated production of tripartite motif protein 25 to inhibit replication of duck viral hepatitis A virus type 1

The innate immune system provides a defense against invading pathogens by inducing various interferon (IFN)-stimulated genes (ISGs). We recently reported that tripartite motif protein 25 (TRIM25), an important ISG, was highly upregulated in duck embryo hepatocyte cells (DEFs) after infection with duck viral hepatitis A virus type 1 (DHAV-1). However, the mechanism of upregulation of TRIM25 remains unknown. Here we reported that interleukin-22 (IL-22), whose expression was highly facilitated in DEFs and various organs of 1-day-old ducklings after DHAV-1 infection, highly enhanced the IFN-λ-induced production of TRIM25. The treatment with IL-22 neutralizing antibody or the overexpression of IL-22 highly suppressed or facilitated TRIM25 expression, respectively. The phosphorylation of signal transducer and activator of transcription 3 (STAT3) was crucial for the process of IL-22 enhancing IFN-λ-induced TRIM25 production, which was suppressed by WP1066, a novel inhibitor of STAT3 phosphorylation. The overexpression of TRIM25 in DEFs resulted in a high production of IFNs and reduced DHAV-1 replication, whereas the attenuated expression of IFNs and facilitated replication of DHAV-1 were observed in the RNAi group, implying that TRIM25 defended the organism against DHAV-1 propagation by inducing the production of IFNs. In summary, we reported that IL-22 activated the phosphorylation of STAT3 to enhance the IFN-λ-mediated TRIM25 expression and provide a defense against DHAV-1 by inducing IFN production.

Background

Global epidemiological data indicates that despite implementation of multiple interventions and significant financial investment, the HIV/AIDS epidemic remained inadequately controlled as of 2020. E-health presents a novel approach in delivering health information and health care and has gained popularity in HIV prevention worldwide. However, evidence on the effectiveness of e-health interventions on HIV prevention among diverse populations remains inadequate. Our study aims to systematically evaluate the effectiveness of varying e-health interventions on HIV prevention, with the objective of providing data support and guidance for the development of future e-health HIV intervention strategies.

Methods

A systematic search of electronic English databases, including MEDLINE through PubMed, Embase, Scopus, and Web of Science, along with three Chinese databases, including National Knowledge Infrastructure (CNKI), Chinese Wanfang Digital Periodicals (WANFANG), and Chinese Science and Technology Periodicals (VIP) database, will be conducted for the period of 1 January 1980 to 31 December 2022. Additionally, gray literature and unpublished trials in trial registers will be searched. Studies aimed at HIV prevention through e-health interventions, with full-text publications available in either English or Chinese, will be included. Study types will be limited to RCT, cluster RCT, and quasi-experiment study. The risk of bias in individual studies will be assessed following the guideline highlighted by the Cochrane Handbook for Systematic Reviews of Interventions. The outcomes will cover cognitive, behavioral, psychological, management, and biological measures of individuals involved in e-health interventions. The quality of evidence will be assessed by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. Ultimately, a systematic review with meta-analysis will be conducted to compare the effectiveness of e-health interventions among diverse populations.

Discussion

This systematic review seeks to establish novel insights into the effectiveness of e-health interventions in diverse populations worldwide. It will inform the design and use of e-health interventions to optimize HIV-related strategies.

Introduction

Drug use is highly prevalent among female sex workers (FSWs). Some forms of drug use, such as injecting drug users (IDU), put them at greater risks for HIV and blood born disease (BBD). In this study, the pattern of drug use and its related factors among Iranian FSWs were investigated.

Materials and methods

This cross-sectional study was performed based on the data of the integrated bio-behavioral surveillance-III (IBBS-III) on FSWs in 8 cities of Iran using the respondent-driven sampling (RDS) method conducting in 2019–2020. Of the 1515 FSWs participating in the IBBS-III study, 1,480 answered questions about drug use. To calculate the prevalence of drug use lifetime and in the past month, weighted analysis was used. Univariate and multivariate logistic regression was used to investigate the factors related to drug use.

Results

The prevalence of lifetime drug use and the prevalence of current drug use (single and poly drug use) among FSWs were estimated to be 29.3% and 18.86%, respectively. According to multivariate regression analysis, the odds ratio (odds) of lifetime drug use showed a statistically significant association with lower education (AOR = 1.18; 95% CI: 1.07–1.3), being a direct sex worker (AOR = 1.77; 95% CI: 1.21–2.61), working in team houses or hangouts (AOR = 1.51; 95% CI: 1.10–2.06), a history of intentional abortion (AOR = 1.41; 95% CI: 1.07–1.87), condom use in the last sex (AOR = 1.61; 95% CI: 1.19–2.17), a history of imprisonment (AOR = 3.05; 95% CI: 2.25–4.14), HIV positive tests (AOR = 8.24; 95% CI: 1.66–40.9), alcohol use (AOR = 1.69; 95% CI: 1.29–2.29), and finding sexual clients in places such as parties, shopping malls, streets, and hotels, or by friends (AOR = 1.46; 95% CI: 1.01–2.12).

Conclusion

Given that drug use among FSWs is about 14 times higher than that of the Iranian general population, it is imperative that drug reduction programs be integrated into service packages. Specifically, prevention programs should be prioritized for occasional drug users within this population as they are at a greater risk of developing drug use issues compared to the general population.

Published: June 2023

Background

To evaluate the second malignant tumors (SMTs) and non-tumor causes of death among patients diagnosed with localized and regional kidney cancer.

Methods

Patients diagnosed with kidney cancer between 2000 and 2017 in the Surveillance, Epidemiology, and End Results (SEER) program database were identified. All causes of death for patients during the follow-up and standardized mortality ratio (SMR) were analyzed.

Result

113,734 patients with localized kidney cancer with 30,390 cases of death were analyzed. 60.4% of the death cases were due to non-tumor caused and 23.6% were second malignant tumors (SMTs). Main SMTs included cancers of lung and bronchus [n = 1,283, SMR: 1.00 (0.95–1.06)] and pancreas [n = 393, SMR: 1.27 (1.15–1.41)]. Causes of death for non-tumor mainly included heart diseases [n = 6,161, SMR: 1.25 (1.21–1.28)] and chronic obstructive pulmonary disease (COPD) [n = 1,185, SMR: 0.99 (0.94–1.05)]. 14,437 of 29,602 patients with regional kidney cancer died. 14.6% of all deaths were due to SMTs and 23.6% due to non-tumor causes. Main SMTs contained bladder cancer [n = 371, SMR: 10.90 (9.81–12.06)] and lung and bronchus cancer [n = 346, SMR: 1.21 (1.08–1.34)]. The main non-tumor death was heart disease [n = 1,424, SMR: 1.26 (1.2–1.33)]. When stratified by pathological types, patients with clear cell renal cell carcinoma (RCC) did not have increased mortality risks of bladder cancer and lung cancer but patients with non-clear cell RCC did.

Conclusion

SMTs and non-tumor diseases including lung and bronchus cancer, bladder cancer, pancreas cancer, diseases of heart, COPD, and cerebrovascular diseases are the leading causes of death besides kidney cancer and should be paid more attention during patients’ survival period.

Background

Sepsis occurs as a result of dysregulated host response to infection. However, cytokine adsorption therapy may restore the balance of proinflammatory and anti-inflammatory mediator responses in patients with sepsis. This study aimed to determine the cytokine adsorption ability of two different types of continuous renal replacement therapy (CRRT) hemofilters for polyethyleneimine-coated polyacrylonitrile (AN69ST) (surface-treated) and polymethylmethacrylate (PMMA) CRRT.

Methods

We performed a randomized controlled trial among sepsis patients undergoing CRRT, who were randomly assigned (1:1) to receive either AN69ST or PMMA-CRRT. The primary outcome was cytokine clearance of hemofilter adsorption (CHA). The secondary endpoints were the intensive care unit (ICU) and 28-day mortalities.

Results

We randomly selected 52 patients. Primary outcome data were available for 26 patients each in the AN69ST-CRRT and PMMA-CRRT arms. The CHA of high-mobility group box 1, tumor necrosis factor, interleukin (IL)-8, monokine induced by interferon-γ, and macrophage inflammatory protein were significantly higher in the AN69ST-CRRT group than in the PMMA-CRRT group (P < 0.001, P < 0.01, P < 0.001, P < 0.001 and P < 0.001, respectively). In contrast, the CHA of IL-6 was significantly higher in the PMMA-CRRT group than in the AN69ST-CRRT group (P < 0.001). In addition, the 28-day mortality was not significantly different between the two groups (50% in AN69ST-CRRT vs. 30.8% in PMMA-CRRT, P = 0.26).

Conclusion

AN69ST and PMMA membranes have different cytokine CHA in patients with sepsis. Therefore, these two hemofilters may have to be used depending on the target cytokine.
