Published: April 2024

Abstract
Background
Primary healthcare in South Africa aims to transform the national health system by emphasising community-based care and preventive strategies. However, rehabilitation services, particularly for individuals with disabilities and chronic non-communicable diseases, are often overlooked in primary healthcare. This study aimed to investigate the provision of primary healthcare rehabilitation services in the Johannesburg Metropolitan District by exploring client sociodemographics and variations in services provided by rehabilitation professionals.

Methods
A retrospective review of clinic rehabilitation records from 2011 to 2020 was conducted at nine provincially funded community health centres (CHCs) offering rehabilitation services. Stratified sampling facilitated record selection based on rehabilitation service type and year. A specifically designed data extraction tool captured demographics, disabilities, rehabilitation received, and referral sources. Descriptive analysis used means, standard deviations, and frequencies.

Results
The findings show a diverse client population with a wide age range, with a significant proportion falling into the < 5 years and 30–49 years age groups. Neuromusculoskeletal and movement-related disabilities were most prevalent, affecting approximately two-thirds of clients. Referral sources were often undocumented, and inconsistent discharge information with no record of patient follow up, highlighted the need for improved documentation practices. Clinic visits were the primary service delivery mode, followed by limited home visits and outreach services. Occupational therapy and physiotherapy were the most used services. Speech and language therapy services were underused, and some CHCs lacked audiology services. There were variations in the number of individual and group sessions provided by the different rehabilitation services, and there were age- and disability-specific differences in service use.

Conclusion
This study offers insights into rehabilitation service provision in the Johannesburg Metropolitan District and enhances our understanding of rehabilitation services in primary healthcare settings. It underscores the importance of a multidisciplinary rehabilitation team to address diverse rehabilitation needs, improving documentation and discharge practices, expanding service delivery models, and reducing disparities in service use. The findings inform strategies for optimising service delivery, workforce, resource allocation, and intersectoral collaboration to ultimately enhance the quality and accessibility of integrated rehabilitation services.
Recognition of nonself is necessary to activate Drosophila’s immune response against an insect parasite

Published: April 2024

Abstract
Background
Innate immune responses can be activated by pathogen-associated molecular patterns (PAMPs), danger signals released by damaged tissues, or the absence of self-molecules that inhibit immunity. As PAMPs are typically conserved across broad groups of pathogens but absent from the host, it is unclear whether they allow hosts to recognize parasites that are phylogenetically similar to themselves, such as parasitoid wasps infecting insects.

Results
Parasitoids must penetrate the cuticle of Drosophila larvae to inject their eggs. In line with previous results, we found that the danger signal of wounding triggers the differentiation of specialized immune cells called lamellocytes. However, using oil droplets to mimic infection by a parasitoid wasp egg, we found that this does not activate the melanization response. This aspect of the immune response also requires exposure to parasite molecules. The unidentified factor enhances the transcriptional response in hemocytes and induces a specific response in the fat body.

Conclusions
We conclude that a combination of danger signals and the recognition of nonself molecules is required to activate Drosophila’s immune response against parasitic insects.
Influence of health food literacy on willingness to pay for healthier foods: focus on food insecurity
Authors: Nam Su-Jung , Suk Jaehye 
Published: April 2024

Abstract
Background
The repercussions of food insecurity are widely recognized to negatively impact overall health and are influenced by a complex interplay of physiological, psychological, social, and environmental factors.

Methods
This study examined the disparities in food consumption and literacy between among food security households and food insecurity households using data from the Korea Rural Economic Institute’s 2022 Consumer Behavior Survey for Food, which involved 3,321 respondents.

Results
Food security households had a greater understanding of and better attitude toward healthier food choices than food insecurity households. Economic ability was identified as having the most significant association with food purchasing behavior, with food security households spending more on average than food insecurity households. Structural equation modeling demonstrated the association of knowledge and attitude with dietary implementation and underscored the significance of consumer literacy as a factor related to willingness to pay for healthier foods.

Conclusions
This study underscores the intertwined relationships among financial capacity, knowledge, and health-conscious dietary choices. It also suggests the need for targeted interventions addressing economic and educational gaps to foster healthier food consumption patterns across different socioeconomic contexts.

Published: April 2024

AbstractMetabolic dysfunction-associated steatotic liver disease (MASLD) has garnered considerable attention globally. Changing lifestyles, over-nutrition, and physical inactivity have promoted its development. MASLD is typically accompanied by obesity and is strongly linked to metabolic syndromes. Given that MASLD prevalence is on the rise, there is an urgent need to elucidate its pathogenesis. Hepatic lipid accumulation generally triggers lipotoxicity and induces MASLD or progress to metabolic dysfunction-associated steatohepatitis (MASH) by mediating endoplasmic reticulum stress, oxidative stress, organelle dysfunction, and ferroptosis. Recently, significant attention has been directed towards exploring the role of gut microbial dysbiosis in the development of MASLD, offering a novel therapeutic target for MASLD. Considering that there are no recognized pharmacological therapies due to the diversity of mechanisms involved in MASLD and the difficulty associated with undertaking clinical trials, potential targets in MASLD remain elusive. Thus, this article aimed to summarize and evaluate the prominent roles of lipotoxicity, ferroptosis, and gut microbes in the development of MASLD and the mechanisms underlying their effects. Furthermore, existing advances and challenges in the treatment of MASLD were outlined.

Published: April 2024

Abstract
Background
Interplay between systemic inflammation and programmed cell death contributes to the pathogenesis of acute lung injury (ALI). cAMP-regulated transcriptional coactivator 1 (CRTC1) has been involved in the normal function of the pulmonary system, but its role in ALI remains unclear.

Methods and results
We generated a Crtc1 knockout (KO; Crtc1−/−) mouse line. Sepsis-induced ALI was established by cecal ligation and puncture (CLP) for 24 h. The data showed that Ctrc1 KO substantially ameliorated CLP-induced ALI phenotypes, including improved lung structure destruction, reduced pulmonary vascular permeability, diminished levels of proinflammatory cytokines and chemokines, compared with the wildtype mice. Consistently, in lipopolysaccharide (LPS)-treated RAW264.7 cells, Crtc1 knockdown significantly inhibited the expression of inflammatory effectors, including TNF-α, IL-1β, IL-6 and CXCL1, whereas their expressions were significantly enhanced by Crtc1 overexpression. Moreover, both Crtc1 KO in mice and its knockdown in RAW264.7 cells dramatically reduced TUNEL-positive cells and the expression of pro-apoptotic proteins. In contrast, Crtc1 overexpression led to an increase in the pro-apoptotic proteins and LPS-induced TUNEL-positive cells. Mechanically, we found that the phosphorylation of Akt was significantly enhanced by Crtc1 knockout or knockdown, but suppressed by Crtc1 overexpression. Administration of Triciribine, an Akt inhibitor, substantially blocked the protection of Crtc1 knockdown on LPS-induced inflammation and cell death in RAW264.7 cells.

Conclusions
Our study demonstrates that CRTC1 contribute to the pathological processes of inflammation and apoptosis in sepsis-induced ALI, and provides mechanistic insights into the molecular function of CRTC1 in the lung. Targeting CRTC1 would be a promising strategy to treat sepsis-induced ALI in clinic.

Published: April 2024

Abstract
Background
Rheumatoid arthritis (RA) is a chronic autoimmune disorder characterized by synovial inflammation, causing substantial disability and reducing life quality. While macrophages are widely appreciated as a master regulator in the inflammatory response of RA, the precise mechanisms underlying the regulation of proliferation and inflammation in RA-derived fibroblast-like synoviocytes (RA-FLS) remain elusive. Here, we provide extensive evidence to demonstrate that macrophage contributes to RA microenvironment remodeling by extracellular vesicles (sEVs) and downstream miR-100-5p/ mammalian target of rapamycin (mTOR) axis.

Results
We showed that bone marrow derived macrophage (BMDM) derived-sEVs (BMDM-sEVs) from collagen-induced arthritis (CIA) mice (cBMDM-sEVs) exhibited a notable increase in abundance compared with BMDM-sEVs from normal mice (nBMDM-sEVs). cBMDM-sEVs induced significant RA-FLS proliferation and potent inflammatory responses. Mechanistically, decreased levels of miR-100-5p were detected in cBMDM-sEVs compared with nBMDM-sEVs. miR-100-5p overexpression ameliorated RA-FLS proliferation and inflammation by targeting the mTOR pathway. Partial attenuation of the inflammatory effects induced by cBMDM-sEVs on RA-FLS was achieved through the introduction of an overexpression of miR-100-5p.

Conclusions
Our work reveals the critical role of macrophages in exacerbating RA by facilitating the transfer of miR-100-5p-deficient sEVs to RA-FLS, and sheds light on novel disease mechanisms and provides potential therapeutic targets for RA interventions.

AbstractHeat shock protein 90 (HSP90) is overexpressed in numerous cancers, promotes the maturation of numerous oncoproteins and facilitates cancer cell growth. Certain HSP90 inhibitors have entered clinical trials. Although less than satisfactory clinical effects or insurmountable toxicity have compelled these trials to be terminated or postponed, these results of preclinical and clinical studies demonstrated that the prospects of targeting therapeutic strategies involving HSP90 inhibitors deserve enough attention. Nanoparticulate-based drug delivery systems have been generally supposed as one of the most promising formulations especially for targeting strategies. However, so far, no active targeting nano-formulations have succeeded in clinical translation, mainly due to complicated preparation, complex formulations leading to difficult industrialization, incomplete biocompatibility or nontoxicity. In this study, HSP90 and CD44-targeted A6 peptide functionalized biomimetic nanoparticles (A6-NP) was designed and various degrees of A6-modification on nanoparticles were fabricated to evaluate targeting ability and anticancer efficiency. With no excipients, the hydrophobic HSP90 inhibitor G2111 and A6-conjugated human serum albumin could self-assemble into nanoparticles with a uniform particle size of approximately 200 nm, easy fabrication, well biocompatibility and avoidance of hepatotoxicity. Besides, G2111 encapsulated in A6-NP was only released less than 5% in 12 h, which may avoid off-target cell toxicity before entering into cancer cells. A6 peptide modification could significantly enhance uptake within a short time. Moreover, A6-NP continues to exert the broad anticancer spectrum of Hsp90 inhibitors and displays remarkable targeting ability and anticancer efficacy both in hematological malignancies and solid tumors (with colon tumors as the model cancer) both in vitro and in vivo. Overall, A6-NP, as a simple, biomimetic and active dual-targeting (CD44 and HSP90) nanomedicine, displays high potential for clinical translation.

Abstract
Background
Bacteria-based cancer therapy have demonstrated innovative strategies to combat tumors. Recent studies have focused on gram-negative bacterial outer membrane vesicles (OMVs) as a novel cancer immunotherapy strategy due to its intrinsic properties as a versatile carrier.

Method
Here, we developed an Human Papillomavirus (HPV)-associated E7 antigen displaying Salmonella-derived OMV vaccine, utilizing a Poly(L-arginine) cell penetrating peptide (CPP) to enhance HPV16 E7 (aa49-67) H-2 Db and OMV affinity, termed SOMV-9RE7.

Results
Due to OMV’s intrinsic immunogenic properties, SOMV-9RE7 effectively activates adaptive immunity through antigen-presenting cell uptake and antigen cross-presentation. Vaccination of engineered OMVs shows immediate tumor suppression and recruitment of infiltrating tumor-reactive immune cells.

Conclusion
The simplicity of the arginine coating strategy boasts the versatility of immuno-stimulating OMVs that can be broadly implemented to personalized bacterial immunotherapeutic applications.

Abstract
Background
Squamous cell carcinoma (SCC) of the dorsum of the tongue is extremely rare, and it clinically resembles various benign lesions. Somatic mutations in TP53 and some driver genes were implicated in the development of SCC; however, the somatic genetic characteristics of dorsal tongue SCC remain unknown. With a detailed analysis of gene mutations in dorsal tongue SCC, we aimed to better understand its biology.

Methods
Four cases of SCC initially occurring on the tongue dorsum were evaluated for clinical and histological findings and immunohistochemical expression of p53 and p16. Gene mutations were analyzed using next-generation sequencing with a custom panel of driver genes.

Results
We retrospectively investigated 557 cases of tongue SCC, and only four cases of SCC initially occurred on the tongue dorsum. The four patients (cases 1–4) were one woman and three men with a mean age of 53.75 years (range: 15–74 years). Histological analysis revealed well-differentiated SCC. Through molecular analysis, we identified pathogenic somatic mutations, namely, TP53 p.C176F (c.527G > T) in case 3 and TP53 p.R282W (c.844 C > T) in case 4. No pathogenic variants were identified in the PI3K/AKT or RAS/RAF pathways. The p53 immunohistochemical examination revealed a wild-type expression pattern in cases 1–3 and strong expression in case 4. The results of p16 immunostaining were negative in all cases.

Conclusions
We described four previously unreported genetic characteristics of dorsal tongue SCC. Somatic TP53 mutations may contribute to the development of a subset of dorsal tongue SCC; however, more cases with genetic analysis need to be accumulated.

Authors: Lubbe Welma , Kubeka Zandile , Behr Ann , Tshitaudzi Gilbert , Dlamini-Nqeketo Sithembile , Botha Jessica 
Published: April 2024

Abstract
Background
The discontinuation of “Mother-Baby Friendly” accreditation, coupled with the impact of the COVID-19 pandemic, has contributed to reduced breastfeeding rates observed in parts of South Africa. Consequently, the Child, Youth and School Health cluster of the National Department of Health, with support from the World Health Organization and United Nations Children’s Fund, organised a Mother-Baby Friendly initiative revitalisation workshop.

Methods
Held in Johannesburg, South Africa, on June 29–30, 2022, the workshop brought together local and international breastfeeding promotion experts to engage on issues related to the revitalisation of the Mother-Baby Friendly Initiative. The workshop included presentations and group sessions aimed at setting expectations, evaluating the Ten Steps to Successful Breastfeeding, and developing actionable revitalisation strategies.

Results
Inadequate monitoring of the Mother-Baby Friendly Initiative implementation and adherence to the Ten Steps was identified as a major implementation bottleneck. Participants identified steps ten (coordinating discharge so that parents and their infants have timely access to ongoing support and care), five (supporting mothers to initiate and maintain breastfeeding and manage common difficulties), and two (ensuring that staff have sufficient knowledge, competence, and skills to support breastfeeding) of the Baby-Friendly Hospital Initiative as the most difficult to implement. Step seven (enabling mothers and their infants to remain together and to practise rooming-in 24 h a day) was the least difficult to implement. Workshop participants identified the following proposed solutions to revitalise breastfeeding promotion: strengthening capacity building and mentorship, improving monitoring and accountability measures, and certification of facilities meeting the initiative’s standards.

Conclusion
Current breastfeeding policies and practices must be evaluated by the National Department of Health in collaboration with provincial and private representatives of the initiative to effectively revitalise the Mother-Baby Friendly Initiative. Moreover, an integrative monitoring framework must be developed through stakeholder engagement, role clarification, and ownership. While collaboration between the private and public sectors is required to promote training and communication within healthcare facilities and communities.

Abstract
Background
The Michigan Hand Outcomes Questionnaire (MHQ) is a self-report tool widely recognized for measuring the health status of patients with hand and wrist problems from a multidimensional perspective. The aim of this study is to translate and culturally adapt the MHQ and validate its psychometric properties of validity, reliability, and responsiveness for different hand problems in Spain.

Methods
The MHQ was translated and culturally adapted following the recommendations of the American Association of Orthopaedic Surgeons. The validation process adhered to the current Consensus-Based Standards for the Selection of Health Status Measurement Instruments (COSMIN) group and was conducted on 262 hand patients. Reliability was assessed through internal consistency using Cronbach's alpha. The study evaluated the test–retest reliability of the measurements using the intraclass correlation coefficient (ICC). Additionally, the measurement error was calculated using the standard error of measurement (SEM) and smallest detectable change (SDC). To assess the structural validity, confirmatory factor analysis (CFA) was employed, while construct validity was evaluated using Pearson's correlation coefficient. Finally, responsiveness was assessed using effect size (ES), standardized response mean (SRM), and minimum clinically important difference (MCID).

Results
The reliability of the test was confirmed through internal consistency analysis, with a good Crombach's Alpha (0.82–0.85), and test–retest analysis, with good values of ICC (0.74–0.91). The measurement error was also assessed, with low values of SEM (1.70–4.67) and SDC (4.71–12.94)). The CFA confirmed the unidimensionality of each scale with goodness of fit indices, while the MHQ showed a high and negative correlation with DASH (r = − 0.75, P < 0.001) and DASH-work (r = − 0.63, P < 0.001) and was irrelevant with EQ-5D (r = − 0.01, P > 0.005) and grip strength (r = 0.05, P > 0.005). At week 5, all 222 patients across the three diagnosed hand subgroups showed moderate to high values above 0.92 for ES and SRM, with one MCID above 6.85.

Conclusions
The MHQ-Sp was culturally adapted, and the results of this version showed good reliability and validity as well as high responsiveness for a wide range of hand conditions after surgical or conservative treatment in Spain.
