Analyzing laboratory test utilization trends in belgian primary care: a decade of insights with international perspectives
Authors: Zayed Ahmed Medhat , Delvaux Nicolas
Published: July 2024

Background

Clinical laboratory testing, essential for medical diagnostics, represents a significant part of healthcare activity, influencing around 70% of critical clinical decisions. The automation of laboratory equipment has expanded test menus and increased efficiency to meet the growing demands for clinical testing. However, concerns about misutilization remain prevalent. In Belgium, primary care has seen a dramatic increase in lab test usage, but recent utilization data is lacking.

Methods

We conducted a comprehensive retrospective analysis of laboratory test utilization trends within the primary care settings of Belgium over a ten-year period, spanning from 2012 to 2021, incorporating a vast dataset of 189 million test records for almost 1.5 million persons. This was the first study to integrate the metadata from both the INTEGO & THIN databases, which are derived from the two major electronic medical record (EMR) systems used in primary care in Belgium, providing a comprehensive national perspective. This research provides crucial insights into patient-level patterns, test-level utilization, and offers international perspectives through comparative analysis.

Results

We found a subtle annual increase in the average number of laboratory tests per patient (ranging from approximately 0.5-1%), indicative of a deceleration in growth in laboratory test ordering when compared to previous decades. We also witnessed stability and consistency of the most frequently ordered laboratory tests across diverse patient populations and healthcare contexts over the years.

Conclusions

These findings emphasize the need for continued efforts to optimize test utilization, focusing not only on tackling overutilization but on enhancing the diagnostic relevance of tests ordered. The frequently ordered tests should be prioritized in these initiatives to ensure their continued effectiveness in patient care. By consolidating extensive datasets, employing rigorous statistical analysis, and incorporating international perspectives, this study provides a solid foundation for evidence-based strategies aimed at refining laboratory test utilization practices. These strategies can potentially improve the quality of healthcare delivery while simultaneously addressing cost-effectiveness concerns in healthcare.

Authors: Li Chunxing , Hu Jisu , Zhang Zhiyuan , Wei Chaogang , Chen Tong , Wang Ximing , Dai Yakang , Shen Junkang
Published: July 2024

Objectives

Exploring the value of adding correlation analysis (radiomic features (RFs) of pelvic metastatic lymph nodes and primary lesions) to screen RFs of primary lesions in the feature selection process of establishing prediction model.

Methods

A total of 394 prostate cancer (PCa) patients (263 in the training group, 74 in the internal validation group and 57 in the external validation group) from two tertiary hospitals were included in the study. The cases with pelvic lymph node metastasis (PLNM) positive in the training group were diagnosed by biopsy or MRI with a short-axis diameter ≥ 1.5 cm, PLNM-negative cases in the training group and all cases in validation group were underwent both radical prostatectomy (RP) and extended pelvic lymph node dissection (ePLND). The RFs of PLNM-negative lesion and PLNM-positive tissues including primary lesions and their metastatic lymph nodes (MLNs) in the training group were extracted from T2WI and apparent diffusion coefficient (ADC) map to build the following two models by fivefold cross-validation: the lesion model, established according to the primary lesion RFs selected by t tests and absolute shrinkage and selection operator (LASSO); the lesion-correlation model, established according to the primary lesion RFs selected by Pearson correlation analysis (RFs of primary lesions and their MLNs, correlation coefficient > 0.9), t test and LASSO. Finally, we compared the performance of these two models in predicting PLNM.

Results

The AUC and the DeLong test of AUC in the lesion model and lesion-correlation model were as follows: training groups (0.8053, 0.8466, p = 0.0002), internal validation group (0.7321, 0.8268, p = 0.0429), and external validation group (0.6445, 0.7874, p = 0.0431), respectively.

Conclusion

The lesion-correlation model established by features of primary tumors correlated with MLNs has more advantages than the lesion model in predicting PLNM.
Parental perceptions and experiences of kangaroo care for preterm infants in neonatal intensive care units in China: a qualitative study
Authors: Cai Qian , Zhou Yunxian , Chen Danqi , Wang Fang , Xu Xinfen
Published: July 2024

Background

kangaroo care (KC), endorsed by the World Health Organization, is an evidence-based intervention that plays a pivotal role in mitigating preterm infant mortality and morbidity. However, this intervention has not been fully integrated into healthcare systems in China. This study aimed to gain insight into parents’ perceptions and experiences of KC for preterm infants to contribute to the KC implementation on a larger scale.

Methods

This study employed a descriptive qualitative design, using face-to-face, semi-structured, in-depth interviews. Fifteen parents participating in KC for preterm infants in the neonatal intensive care units (NICUs) were purposively sampled from four hospitals across four cities in Zhejiang Province, China. Thematic analysis was employed to analyze the data.

Results

Four themes and twelve subthemes regarding the parents’ perceptions and experiences about KC were identified. The four themes included: (1) Low motivation upon initial engagement with KC, (2) Dynamic fluctuations of emotional states during KC, (3) Unexpected gains, and (4) Barriers to participation.

Conclusions

Parents’ perceptions and experiences of KC was a staged process, with parents exhibiting distinct cognitive patterns and unique experiences at each stage. Overall, as KC progresses, parents’ experiences tended to become increasingly positive, despite potential obstacles encountered along the way. To enhance the implementation of KC, healthcare providers could utilize prenatal and postnatal education programs. These programs aim to enhance the understanding of KC among parents of preterm infants, fostering sustained engagement in KC practices.
Needs & networks: understanding the role and impact of social networks on HIV (self-)testing among GBMSM and trans people in England and Wales

Published: July 2024

Background

Understanding how HIV self-testing (HIVST) can meet the testing needs of gay, bisexual and other men who have sex with men (GBMSM) and trans people whose social networks vary is key to upscaling HIVST implementation. We aim to develop a contextual understanding of social networks and HIV testing needs among GBMSM (cis and transgender) and trans women in SELPHI (An HIV Self-testing Public Health Intervention), the UK’s largest randomised trial on HIVST.

Methods

This study re-analysed qualitative interviews conducted from 2015 to 2020. Forty-three in-person interviews were thematically analysed using the Framework Method. Our analytic matrix inductively categorised participants based on the unmet needs for HIV testing and the extent of social network support. The role of social networks on HIVST behaviour was explored based on individuals’ testing trajectories.

Results

Four distinct groups were identified based on their unmet testing needs and perceived support from social networks. Optimisation advocates (people with high unmet needs and with high network support, n = 17) strived to tackle their remaining barriers to HIV testing through timely support and empowerment from social networks. Privacy seekers (people with high unmet needs and with low network support, n = 6) prioritised privacy because of perceived stigma. Opportunistic adopters (people with low unmet needs and with high network support, n = 16) appreciated social network support and acknowledged socially privileged lives. Resilient testers (people with low unmet needs and with low network support, n = 4) might hold potentially disproportionate confidence in managing HIV risks without sustainable coping strategies for potential seroconversion. Supportive social networks can facilitate users’ uptake of HIVST by: (1) increasing awareness and positive attitudes towards HIVST, (2) facilitating users’ initiation into HIVST with timely support and (3) affording participants an inclusive space to share and discuss testing strategies.

Conclusions

Our proposed categorisation may facilitate the development of differentiated person-centred HIVST programmes. HIVST implementers should carefully consider individuals’ unmet testing needs and perceived levels of social support, and design context-specific HIVST strategies that link people lacking supportive social networks to comprehensive HIV care.
Sex differences in formal recommendation of assets for health (social prescribing) in Aragon
Authors: Pola-Garcia Marina , Benede Azagra Carmen Belen , Enriquez Martin Natalia , Lou Alcaine Maria Luz , Melus-Palazon Elena , Mendez-Lopez Fatima , Gasch-Gallen Angel
Published: July 2024

Background

In primary health care, social prescribing is an important tool which is gaining popularity. It is being studied significantly, however there is not enough evidence about different related issues. The aim of this study is to analyse the differences by sex in the application of a social prescription protocol in Primary Care.

Methods

This is a cross-sectional study carried out with data from the Electronic Health Record between September 2018 and March 2021. Descriptive, bivariate and multivariate analyses of data from 2,109 records of Social Prescription protocol in primary health care centers located in Aragón in northern Spain (Europe) were performed using Jamovi Statistics software (version 2.3.28). The comparisons by sex were carried out using a Mann-Whitney U or chi-squared test to analyse differences.

Results

The protocol was used correctly 1,482 times, where it was applied more in females (74.8% female vs. 25.2% male). The median age in females was higher than males (female 72 vs. males 70; p = 0.003). There were significant differences by sex in several aspects to strengthen with the social prescribing, physical, emotional and relational skills. Most females and males regularly attended the recommended asset and there were significant differences in the group that never attended. Mean satisfaction was statistically different, with 4.74 points out of 5 for females and 4.86/5 for males (p = 0.010). It can be observed that older females in rural areas (OR = 34.15), whose social prescription acts on Emotional Skills and Relational and Social Skills (OR = 6.10–8.23), with good prior self-care and greater participant satisfaction (OR = 8.96), have greater chance of improving their health.

Conclusions

Some results showed sex differences in the use and outcomes of formal asset recommendation. However, further research is needed to assess the relationship between social prescription, sex and gender and their implications.
Tax increases as an incentive to quit smoking: is thinking about quitting due to a tobacco tax increase associated with post-tax increase smoking cessation?
Authors: Geboers Cloé , Candel Math J. J. M. , Nagelhout Gera E. , van den Putte Bas , Willemsen Marc C.
Published: July 2024

Background

The cost of tobacco is one of the most reported reasons to quit smoking. The Netherlands increased tobacco taxes twice in the span of nine months: a €1 increase per pack in April 2020, and a €0.12 increase per pack in January 2021. This study examines to what extent people report to think about quitting due to the upcoming tax increase(s), as well as how it relates to their age, income or educational level. Additionally, we examined whether thinking about quitting was associated with quit intention and quit behaviour, and whether these associations were different for the two tax increases.

Methods

Longitudinal data from the International Tobacco Control (ITC) Netherlands Surveys, Cohort 2 were used (N = 5919 observations; wave 1 (February – March 2020): n = 2051; wave 2 (September – November 2020): n = 1919; wave 3 (June – July 2021): n = 1949). Generalised Estimating Equation (GEE) regressions were fit to test the associations between thinking about quitting due to the tax increase and post-tax increases in quit intention, serious quit attempts, and quitting smoking (≤ 1 cigarette a month), as well as sociodemographic variables.

Results

Circa half of the people who smoke reported thinking about quitting smoking due to the upcoming tax increase (Wave 1 = 51.3% (n = 1052); Wave 2 = 47.3% (n = 849)). Individuals who reported thinking about quitting smoking due to upcoming tax increase(s) were more likely to have increased their quit intention (aOR: 2.00, p ≤ .001) or have carried out a serious quit attempt (aOR:1.48, p ≤ .001) post-tax increase. More people attempted to quit smoking between wave 2 and 3 (post 2021 increase) than between wave 1 and 2 (post 2020 increase). We did not find an interaction effect between wave and thinking about quitting for quit intention, quit attempts, and quitting smoking.

Conclusions

Tax increases stimulate people to think about quitting. Thinking about quitting due to an upcoming tax increase was associated with more positive quit intention and serious quit attempts.
Association of psychological resilience with all-cause and cause-specific mortality in older adults: a cohort study
Authors: Wang Xiang , Jie Wei , Huang Xionghong , Yang Feng , Qian Yueting , Yang Ting , Dai Miao
Published: July 2024

Background

Psychological resilience has been associated with increased longevity in the oldest old; however, its significance in the broader older adult population has not been thoroughly explored. There is a lack of understanding regarding its relationship with cause-specific mortality in older adults. This study aims to address these gaps by investigating the association between psychological resilience and both overall mortality and cause-specific mortality in individuals aged 65 and older.

Methods

We enrolled 4,935 participants aged 65 and older in the Chinese Longitudinal Healthy Longevity Survey, with baseline assessments conducted in 2014 and follow-up surveys in 2018. To evaluate the associations between psychological resilience and mortality, we used Cox proportional hazards models. Additionally, we employed restricted cubic spline plots to illustrate the dose-response relationships between these variables.

Results

During a mean (Standard Deviation) follow-up of 3.2 years (1.2), 1726 participants died. Higher psychological resilience was independently associated with lower all-cause mortality risk (Hazard ratio [HR] 0.74, 95% confidence interval [CI]: 0.67–0.82) and cause-specific mortality from cardiovascular disease (HR 0.74, 95% CI: 0.59–0.93), respiratory diseases (HR 0.63, 95% CI:0.45–0.87), and other causes (HR 0.69, 95% CI: 0.60–0.78), excluding cancer-related mortality. Similar effects were evident when examining the psychological resilience score. The dose-response analysis further indicated a gradual decrease in mortality risk corresponding to higher psychological resilience scores. Interaction analyses revealed that psychological resilience has a more pronounced effect on mortality from other causes among economically independent older adults (P-interaction = 0.02).

Conclusions

Enhanced psychological resilience is independently associated with reduced all-cause and some cause-specific mortality in older adults. These findings underscore the importance of addressing psychological factors in the promotion of healthy aging and longevity.

Published: July 2024

Introduction

Radiation Therapy and IRreversible Electroporation for Intermediate Risk Prostate Cancer (RTIRE) is a phase II clinical trial testing combination of radiation therapy and irreversible electroporation for intermediate risk prostate cancer

Background

PCa is the most common non-cutaneous cancer in men and the second leading cause of cancer death in men. PCa treatment is associated with long term side effects including urinary, sexual, and bowel dysfunction. Management of PCa is based on risk stratification to prevent its overtreatment and associated treatment-related toxicity. There is increasing interest in novel treatment strategies, such as focal therapy, to minimize treatment associated morbidity. Focal therapy alone has yet to be included in mainstream guidelines, given ongoing concerns with potentially higher risk of recurrence. We hypothesize combining focal therapy with whole gland, reduced dose radiotherapy will provide acceptable oncologic efficacy with minimal treatment associated morbidity. RTIRE is a phase II single institution, investigator-initiated study combining a local ablative technique though local irreversible electroporation (IRE) with MR guided RT (MRgRT) to treat the entire prostate. The goal is to provide excellent oncologic outcomes and minimize treatment related side effects through leveraging benefits of locally ablative therapy with established radiation treatment techniques.

Methods

A total of 42 men with intermediate risk PCa per NCCN guidelines and focal grade group (GG) 2 or 3, Gleason Score (GS) 3 + 4 or GS 4 + 3, cancer in an MRI target will be enrolled. Patients with MRI visible foci of GG2/GG3 will undergo focal therapy with IRE of this lesion. Following successful focal therapy, patients will then undergo a course of reduced dose, whole gland MRgRT with either 32.5 Gy in 5 Fractions or 22 Gy in 2 fractions. The primary objective of the study is to determine safety. Secondary outcomes include evaluation of oncologic efficacy (as measured by the proportion of patients free of clinically significant cancer as defined as > Grade Group 1 at 1-year follow-up biopsy), imaging characteristics of patients pre and post RTIRE, impact on quality of life (QoL), and PSA kinetics.

Discussion

Combining IRE with a reduced dose radiotherapy may offer a new treatment paradigm for PCa by both reducing treatment effects of full dose radiotherapy and minimizing the risk of recurrence observed with focal therapy.

Authors: Ouyang Tianfeng , Chen Dong , Ma Zeli , Li Xin , Cao Ge , Lin Lin , Zeng Ming , Chen Ting
Published: July 2024

Background

Non-syndromic tooth agenesis (NSTA) is a type of ectodermal dysplasia (ED) in which patients with non-syndromic oligodontia may only affect teeth. No pathological findings were found in other tissues of the ectodermal. Herein, we report a case of a NSTA patient with severe dental anxiety and poor oral health.

Case presentation

A 5-year-old boy without systemic diseases presented as a patient with oligodontia, extensive caries, and periapical periodontitis. Molecular genetic analysis found a mutation in the Ectodysplasin A (EDA) gene, confirming the diagnosis of NSTA.

Conclusion

Tooth agenesis (TA) is the most common ectodermal developmental abnormality in humans. Non-syndromic oligodontia patients often seek treatment in the department of stomatology. Because of their complex oral conditions, these patients should be provided with a systematic and personalized treatment plan.

Published: July 2024

Object

To analyze the trend of the coupling and coordination of the supply and demand of healthcare resources between the elderly population and healthcare resources in China during the period of 2012–2022, to reveal the impact of the growth of the elderly population on the relationship between the supply and demand of healthcare resources, and to put forward suggestions to improve the coupling and coordination between the supply and demand of healthcare resources and the elderly population, in order to cope with the challenges of an aging society.

Methods

By obtaining relevant data from authoritative data sources such as China Statistical Yearbook, Health and Health Statistics Yearbook, and the Chinese government website from 2012 to 2022, we constructed a comprehensive measurement index for the three systems of elderly population, healthcare resource supply, and healthcare resource demand; Using the entropy value method to assign weights to the indicators, combined with the coupling coordination degree model, to reveal the changes of the elderly population change and the supply and demand of medical and health resources; using ArcGIS technology, to study the spatial characteristics of the elderly population change and the supply and demand of medical and health resources.

Results

From 2012 to 2022, the supply and demand of healthcare resources and the variation of the elderly population in China show a continuous growth trend, and the comprehensive development level of the system gradually climbs from a low level to a high level. The fluctuation of coupling degree and coordination degree rises, although the coordination degree has always been lower than the coupling degree, but the distance between the coordination degree and the coupling degree gradually narrows with the passage of time. The coordination degree between population aging and medical and health resources development shows spatial heterogeneity in China, with the eastern region significantly higher than the western region/.

Conclusions

The coupling degree between population aging and healthcare resource supply and demand in China from 2012 to 2022 shows a general upward trend from low coupling to medium-high coupling, but it is worth noting that even though the degree of coupling increases, the degree of coordination is still relatively lagging behind, suggesting that the government and relevant departments need to pay more attention to coordinated allocation and management of healthcare resources. At the same time, the spatial differences in the degree of coordination among provinces suggest that future policymakers should take regional differences into full consideration in policymaking and sustainable development.

Published: July 2024

Ubiquitination, a pivotal posttranslational modification of proteins, plays a fundamental role in regulating protein stability. The dysregulation of ubiquitinating and deubiquitinating enzymes is a common feature in various cancers, underscoring the imperative to investigate ubiquitin ligases and deubiquitinases (DUBs) for insights into oncogenic processes and the development of therapeutic interventions. In this review, we discuss the contributions of the ubiquitin–proteasome system (UPS) in all hallmarks of cancer and progress in drug discovery. We delve into the multiple functions of the UPS in oncology, including its regulation of multiple cancer-associated pathways, its role in metabolic reprogramming, its engagement with tumor immune responses, its function in phenotypic plasticity and polymorphic microbiomes, and other essential cellular functions. Furthermore, we provide a comprehensive overview of novel anticancer strategies that leverage the UPS, including the development and application of proteolysis targeting chimeras (PROTACs) and molecular glues.
Association of triglyceride-glucose index and delirium in patients with sepsis: a retrospective study
Authors: Fang Yipeng , Dou Aizhen , Shen Yuehao , Li Tianyu , Liu Haiying , Cui Yan , Xie Keliang
Published: July 2024

Objective

It is well known that glucose and lipid metabolism disorders and insulin resistance are common in sepsis, which affect the occurrence and prognosis of multiple organ dysfunction in septic patients. Previous study reported the predictive value of triglyceride-glucose index (TyG), a clinical indicator for insulin resistance, in postoperative delirium patients. However, it remains unclear whether the TyG index is a novel predictive biomarker for sepsis-associated delirium. The aim of this study is to explore the relationship between TyG index and the risk of delirium in patients with sepsis.

Methods

Adult septic patients were identified from the MIMIC-IV database and divided into four groups based on the mean value of TyG. The primary outcome was the incidence of delirium. The association between TyG and the risk of developing delirium was evaluated by restricted cubic spline (RCS), multivariate logistic regression and subgroup analysis. Propensity Score Matching (PSM) method was used to balance the baseline data.

Results

A total of 3,331 septic patients were included in the analysis, and further divided into four groups: Q1 (TyG ≤ 8.67), Q2 (8.67 < TyG ≤ 9.08), Q3 (9.08 < TyG ≤ 9.61), and Q4 (TyG > 9.61). The RCS curves demonstrated a non-linear positive relationship between TyG index and the risk of developing delirium, and an optimal cut-of value 9.09 was recommended. After balancing the baseline information by PSM, patients in the TyG > 9.09 group had a significant higher incidence of delirium compared with those in the TyG ≤ 9.09 group. In logistic regression analysis, TyG > 9.09 was significantly associated with lower risk of developing delirium in both original cohort (OR 1.54–1.78, all P < 0.001) and the PSM cohort (OR 1.41–1.48, all P < 0.001). No association was found between the TyG index and mortality (all P > 0.05). In subgroup analysis, our findings were consistent (all OR > 1 in all subgroups).

Conclusion

Our study demonstrated an independent association between TyG index and increased risk of delirium in septic patients, indicating that TyG index can serve as a biomarker for delirium in sepsis.

Authors: Ikawa Hiroaki , Koto Masashi , Fugo Kazunori , Takiyama Hirotoshi , Isozaki Tetsuro , Shinoto Makoto , Yamada Shigeru , Ishikawa Hitoshi
Published: July 2024

Background

Clear cell odontogenic carcinoma (CCOC) is a rare odontogenic malignant tumor. The standard treatment for CCOC is surgical resection and adjuvant radiotherapy (RT). Radiotherapy is generally considered in inoperable cases. However, there are no reports on definitive RT for CCOC, and the role of RT in patients with inoperable CCOC remains unknown. Therefore, in this report, we present two cases of carbon-ion (C-ion) RT for CCOC.

Case presentation

In case 1, a 73-year-old man with mandibular CCOC presented with recurrence in the inferior temporal fossa after two tumor resections. The tumor was considered inoperable, and C-ion RT (57.6 Gy in 16 fractions) was administered. The tumor remained controlled even after 20 months of C-ion RT; however, the patient died of other causes. In case 2, a 34-year-old man with maxillary CCOC presented with recurrence in the left sinonasal region after two tumor resections. The tumor was considered inoperable, and C-ion RT (64 Gy in 16 fractions) was administered. However, recurrence was observed in the irradiated field 19 months after the treatment. Subsequently, C-ion RT (64 Gy in 16 fractions) was repeated for the recurrent tumors. Seven years and 6 months after the initial irradiation, the tumor remains controlled, and the patient is alive without any unexpected serious adverse events.

Conclusion

C-ion RT may be an effective treatment option for patients with inoperable CCOC.
Cancer-associated fibroblast-derived WNT5A promotes cell proliferation, metastasis, stemness and glycolysis in gastric cancer via regulating HK2
Authors: Xu Yongsu , Ren Zhengju , Zeng Fang , Yang Huan , Hu Chengju
Published: July 2024

Background

Gastric cancer (GC) is one of the most common cancers worldwide. Tumor microenvironment plays an important role in tumor progression. This study aims to explore the role of cancer-associated fibroblasts (CAFs) in GC and the underlying mechanism.

Methods

Cell viability, proliferation, invasion and migration were assessed by MTT, EdU, transwell and wound healing assays, respectively. Sphere formation assay was used to evaluate cell stemness. Glucose consumption, lactate production and ATP consumption were measured to assess glycolysis. In addition, The RNA and protein expression were detected by qRT-PCR and western blot. The interaction between wingless Type MMTV Integration Site Family, Member 5 A (WNT5A) and hexokinase 2 (HK2) was verified by Co-immunoprecipitation. The xenograft model was established to explore the function of CAFs on GC tumor growth in vivo.

Results

CAFs promoted the proliferation, metastasis, stemness and glycolysis of GC cells. WNT5A was upregulated in CAFs, and CAFs enhanced WNT5A expression in GC cells. Knockdown of WNT5A in either GC cells or CAFs repressed the progression of GC cells. In addition, WNT5A promoted HK2 expression, and overexpression of HK2 reversed the effect of WNT5A knockdown in CAFs on GC cells. Besides, knockdown of WNT5A in CAFs inhibits tumor growth in vivo.

Conclusion

CAF-derived WNT5A facilitates the progression of GC via regulating HK2 expression.
Health and equity impacts of global consultancy firms
Authors: Anaf Julia , Baum Fran
Published: July 2024

Background

Concern is growing over the power, influence, and threats to health and equity from the operations of large global consultancy firms. Collectively, these firms support a neoliberal policy environment promoting business interests ahead of public health. Global consultancy firms act as commercial determinants of health, an evolving area of research over recent years. However, this research mainly focuses on specific corporations or industry sectors, especially those which produce harmful products, including ultra-processed food, alcohol, and fossil fuels. It is therefore important to expand the focus to include large global consultancy firms and place a public health and equity lens over their operations.

Main body

Global consultancy firms have wide-ranging conflicts of interest. These arise from the ‘revolving door’ employment strategies between their own staff and those from government and regulatory bodies. These firms also advise governments on taxation and other matters while concurrently advising corporate clients on ways to minimise taxation. They advise fossil fuel corporations while also advising governments on climate and health policies. These firms undermine the capabilities of the public sector through the outsourcing of traditional public sector roles to these private interests. Consultancy firms foster private interests through their engagement with the higher education sector, and thereby weaken the tradition of transparent management of university affairs by accountable university councils. While private consultancies cannot be blamed for all the negative consequences for health and equity caused by the problems associated with globalisation and advanced capitalism, they have played a role in amplifying them.

Conclusion

Addressing the negative impacts of global consultancy firms will require strengthening the public sector, enforcing greater transparency, accountability, and minimising conflicts of interest. It will also demand critical thought, counter discourses, and activism to reframe the narratives supporting neo-liberal ideas of governance that are promoted in both government and business arenas.
Prevalence and location of inflammatory and structural lesions in patients with rheumatoid arthritis and radiographic axial spondyloarthritis with chronic neck pain evaluated by magnetic resonance imaging
Authors: Kiefer David , Soltani Mina , Damirchi Parham , Kiltz Uta , Buehring Bjoern , Andreica Ioana , Sewerin Philipp , Baraliakos Xenofon
Published: July 2024

Objective

Define the prevalence and location of inflammatory and structural lesions on magnetic resonance imaging (MRI) in patients with rheumatoid arthritis (RA) and radiographic axial spondyloarthritis (r-axSpA) with neck pain as leading clinical symptom.

Methods

Patients with diagnosis of RA and r-axSpA were consecutively included if they had chronic (> 3 months) neck pain. Clinical assessment, neck pain questionnaires and MRIs of the cervical spine (CS) were performed.

Results

107 patients (59 RA and 48 r-axSpA) were included. While there was no difference in the Northwick-Park-Neck-Pain-questionnaire, patients with RA reported higher neck pain compared to r-axSpA on a numeric rating scale (5.0 ± 3.6 vs. 3.0 ± 3.1; p = 0.003). Inflammatory lesions occurred predominantly in the craniocervical area in RA and in the lower CS segments in r-axSpA. Bone marrow edema (BME) was more frequent in axSpA (BME-score axSpA/RA: 0.35vs0.17; p < 0.001) while synovitis was visible in both but was more prevalent in RA (synovitis-score axSpA/RA: 0.02vs0.1; p < 0.001). BME was found in 8 (13.6%) vertebral corner vs. 9 (18.8%), in 2 (3.4%) facet joints vs. 7 (14.6%) and in 1 (1.7%) spinous processes vs. 9 (18.8%) in patients with RA/r-axSpA. In contrast, more patients with RA (30.5% vs6.3%) showed erosive osteochondrosis with endplate BME (p = 0.002).

Conclusion

While involvement of upper cervical inflammation was typically present in RA, r-axSpA patients showed more BME in lower CS segments, vertebral corners, facet joints and spinous processes. Neck pain is linked to upper and lower inflammatory and structural lesions of the CS in both diseases.
Reparative effects of Schizophyllum commune oat bran fermentation broth on UVB-induced skin inflammation via the JAK/STAT pathway
Authors: Song Zixin , Geng Jiman , Wang Dongdong , Fang Jiaxuan , Wang Ziwen , Wang Changtao , Li Meng
Published: July 2024

Human immortal keratinocyte cells (HaCaT) are induced with UVB to establish an injury model. This model is utilized to investigate whether oat bran fermentation broth (OBF) has a reparative effect on skin inflammation and damage to the skin barrier caused by UVB irradiation. The results show that compared with unfermented oat bran (OB), OBF exhibits higher structural homogeneity, increased molecular weight size, active substances content, and in vitro antioxidant activity. OBF has a scavenging effect on excess reactive oxygen species (ROS) and increases the intracellular levels of antioxidant enzymes. It was found that OBF has a stronger inhibitory effect on the release of inflammatory factors than OB. It increases the synthesis of AQP3 and FLG proteins while decreasing the secretion of KLK-7. OBF can inhibit the transcription level of inflammatory factors by suppressing the JAK/STAT signaling pathway. Safety experiments demonstrate that OBF has a high safety profile.

Background

Dropped head syndrome (DHS) is caused by dysfunction of the cervical musculature. It is classified into two groups according to the cause: one is weakness of the neck extensors and the other is hypercontraction of the cervical flexors associated with Parkinson’s disease and other disorders. Although some drugs have previously been reported as suspected causes of DHS, we are unaware of any reports in which oxaliplatin was suspected. In this report, we describe a case of DHS during adjuvant chemotherapy for gastric cancer, along with a review of the relevant literature.

Case presentation

A 72-year-old man was diagnosed with gastric cancer, cT3N0M0 cStage IIB, and underwent laparoscopic total gastrectomy with D2 lymphnode dissection and Roux-en-Y reconstruction. The operative time was 311 min, intraoperative blood loss was 40 g, and he was discharged without any post-operative complications. The histopathological diagnosis was pT4aN2M0 pStage IIIA, and S-1 + oxaliplatin (SOX) therapy was started as adjuvant chemotherapy. On the 4th course of SOX, he complained of neck heaviness and a blood test revealed that his creatine kinase (CK) level was elevated to 2464 IU/L. After consultation with an orthopedic surgeon and a neurologist, DHS due to localized cervical extensor myositis was suspected. Therefore, the 6th course of SOX was postponed, and 30 mg of oral steroids were initiated. His symptoms improved, and his CK level decreased within 2 weeks. After resuming S-1 monotherapy and tapering off oral steroids, no recurrence of symptoms has been observed.

Conclusions

We experienced one case of DHS during adjuvant chemotherapy for gastric cancer. If DHS develops after starting oxaliplatin, involvement of the drug should be suspected, and discontinuation of chemotherapy and introduction of oral steroids should be considered.

Background

Although the usefulness of pulmonary function tests has been established for lung resection and coronary artery bypass surgeries, the association between preoperative pulmonary function test and postoperative respiratory complications in nonpulmonary and noncardiac surgery is inconclusive. The purpose of this study was to determine the association between preoperative forced expiratory volume in one second (FEV1) on pulmonary function test and the development of postoperative respiratory failure and/or death in patients undergoing major nonpulmonary and noncardiac surgery.

Methods

Adult patients aged ≥ 18 years and who underwent nonpulmonary and noncardiac surgery with expected moderate to high risk of perioperative complications from June 2012 to March 2019 were included. The primary exposure was preoperative FEV1 measured by pulmonary function test within six months before surgery. The primary outcome was respiratory failure (i.e., invasive positive pressure ventilation for at least 24 h after surgery or reintubation) and/or death within 30 days after surgery. A logistic regression model was used to adjust for the respiratory failure risk index, which is a scoring system that predicts the probability of postoperative respiratory failure based on patient and surgical factors, and to examine the association between preoperative FEV1 and the development of postoperative respiratory failure and/or death.

Results

Respiratory failure and/or death occurred within 30 days after surgery in 52 (0.9%) of 5562 participants. The incidence of respiratory failure and/or death in patients with FEV1 ≥ 80%, 70%– < 80%, 60%– < 70%, and < 60% was 0.9%, 0.6%, 1.7%, and 1.2%, respectively. Multivariable logistic regression analysis showed no significant association between preoperative FEV1 and postoperative respiratory failure and/or death (adjusted odds ratio per 10% decrease in FEV1: 1.01, 95% confidence interval: 0.88–1.17, P = 0.838). Addition of FEV1 information to the respiratory failure risk index did not improve the prediction of respiratory failure and/or death [area under the receiver operating characteristics curve: 0.78 (95% confidence interval: 0.72–0.84) and 0.78 (95% confidence interval: 0.72–0.84), respectively; P = 0.84].

Conclusion

We found no association between preoperative FEV1 and postoperative respiratory failure and/or death in patients undergoing major nonpulmonary and noncardiac surgery.
Relationship between night eating syndrome and sleep quality among university students in Palestine

Published: July 2024

Background

Night eating syndrome (NES) is an eating disorder in which at least one-third of one’s daily caloric intake is consumed after the last meal of the day or throughout the nocturnal evening on at least two consecutive occasions each week. In the literature, the prevalence of NES among university students ranged from 4.2 to 15%.

Aim

The purpose of this study was to find out how common NES is among Palestinian university students, as well as the association between NES, sleep quality, BMI, socioeconomic factors, and lifestyle factors.

Methods

Students from An-Najah National University completed an online questionnaire. The Pittsburgh Sleep Quality Index (PSQI) and the Eating Questionnaire (NEQ) were employed.

Results

A total of 333 participants took part in the study. The average age of the participants was 21.66 years (range: 16 to 33). The presence of NES was identified in 82.6% of the study subjects. There was no evidence of a link between NES and BMI, sociodemographic variables, or lifestyle factors. Higher scores on subjective sleep quality (p < .01), sleep latency (p < .01), and daytime dysfunction (p < .05) scores were found to be linked with NES. Additional to this, the NEQ scores were shown to be substantially connected with these scores, as well as the sleep duration scores (p < .05). Subjective sleep quality (p < .01) and sleep latency (p < .01) were revealed to be significant predictors of the NEQ score.

Conclusion

NES was significantly related to sleep quality subscales among Palestinian university students. Moreover, subjective sleep quality and sleep latency predicted NEQ score.

PURPOSE

Breast cancer is the most frequently diagnosed cancer in women worldwide. Surgery is a major treatment modality for breast cancer, and over the years, breast-conserving surgeries with breast radiation have shown similar outcomes with mastectomy. Not much is known about the frequency and outcome of breast-conserving surgery in Africa. This systematic review provides a comprehensive summary of the evidence evaluating cosmetic and oncologic outcomes after oncoplastic breast-conserving surgery (OBCS) for breast cancer in African women.

METHODS

This review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Databases were systematically searched for studies on African women undergoing OBCS. The oncologic and cosmetic outcomes, as well as the localization and reconstruction techniques, were evaluated. Descriptive statistics were used to summarize the frequency and proportions of the extracted variables.

RESULTS

The literature search yielded 266 articles but only 26 of these were included in the review. Majority of the studies were from Egypt and South Africa. These studies collectively evaluated 1,896 patients with a mean age of 48.2 years and a mean follow-up period of 36.9 months. The most common histopathology was T2 (71.4%) invasive ductal carcinoma. Hook wire localization was the most common technique used for nonpalpable lesions in 85.3% of patients. Of the studies reporting oncoplastic technique, the latissimus dorsi volume replacement technique was the most reported (15%). Most patients were satisfied with their cosmetic outcome. Seroma was the most common postoperative complication (44.6%). Among studies that reported oncologic outcome data, the crude overall survival and disease-free survival were 93.1% and 89.4%, respectively.

CONCLUSION

This systematic review revealed that the outcome of OBCS in African women compares with that in developed countries.

PURPOSE

Many cancer survivors have ongoing follow-up with their oncologist(s), despite evidence that this care can be competently managed by primary care and transitioning well survivors could relieve growing pressure on cancer care systems. We analyzed population-based administrative data from Ontario, Canada, to examine rates of transition to primary care–led follow-up care during the survivorship phase, including clinical and demographic predictors associated with being transitioned.

METHODS

We conducted a retrospective cohort study to describe the patterns of survivorship follow-up care among all patients with breast cancer in Ontario from 2006 to 2016. Data were derived from the Ontario Cancer Registry and other linked data sets. We defined the survivorship phase of care beginning at 2 years after initial diagnosis. Logistic regression was used to explore factors potentially prognostic of no oncology visits in each of the years after survivorship.

RESULTS

Our survivorship cohort was composed of 71,719 patients with breast cancer, 42% of whom were considered to have transitioned from oncology to primary care 2 years after diagnosis. Although the number of patients having oncology visits diminished over time, a quarter of the cohort continued being seen in year 5 of survivorship. Regression analysis found older age, early cancer stage, living farther from a cancer center, not receiving radiation or chemotherapy, and high well-being to be associated with transitioning to primary care.

CONCLUSION

Our findings contribute to the development of low-risk profiles among survivors to inform optimal transition from oncology to primary care. Further research examining qualitative perspectives from oncologists, cancer survivors, and primary care is also required to illuminate other sentinel factors to be considered when transitioning during follow-up.
