Abstract
Objective
To retrospectively analyze the safety and long-term clinical efficacy of gelatin sponge microparticles combined with the chemotherapy drug pirarubicin for hepatic transcatheter arterial chemoembolization (GSMs-TACE) in order to treat breast cancer liver metastasis (BCLM).

Methods
Twenty-seven BCLM patients who underwent GSMs-TACE from July 2010 to July 2016 were enrolled. Tumor target blood vessels were slowly and regionally embolized with absorbable gelatin sponge particles and pirarubicin injections. Plain computed tomography (CT) scans and biochemical indexes were re-examined at 4 days after treatment, and enhanced CT scans or magnetic resonance images and biochemical indexes, 1 month later. For patients with stable tumors, the follow-up period was 2 to 3 months, and the tumor response was evaluated using Modified Response Evaluation Criteria in Solid Tumors. Adverse reactions, survival time, and prognostic factors were assessed.

Results
By October 2019, 27 patients with BCLM had undergone GSMs-TACE, with an average of 2.44 ± 1.58 treatments. The 1-, 3-, and 5-year survival rates were 62.96%, 22.22%, and 14.81%, respectively, and the mOS was 22.0 months. No serious complications, such as acute liver failure and liver abscess, had occurred. There were two cases of acute cholecystitis that recovered after symptomatic treatment. Multivariate analysis of the prognosis showed that the primary tumor size, number of metastatic lymph nodes, estrogen receptor/progesterone receptor (ER/PR) status, and time to postoperative liver metastasis and combination therapy were statistically significant.

Conclusions
The overall prognosis of BCLM was poor. GSMs-TACE was safe and effective for BCLM treatment and could prolong the median survival time of patients. Therefore, it is worthy of widespread clinical application.

Abstract
Background
Colorectal cancer (CRC) is one of the most common cancers of the gastrointestinal tract and ranks third in cancer-related deaths worldwide. This study was conducted to identify novel biomarkers related to the pathogenesis of CRC based upon a bioinformatics analysis, and further verify the biomarkers in clinical tumor samples and CRC cell lines.

Methods
A series of bioinformatics analyses were performed using datasets from NCBI-GEO and constructed a protein–protein interaction (PPI) network. This analysis enabled the identification of Hub genes, for which the mRNA expression and overall survival of CRC patients data distribution was explored in The Cancer Genome Atlas (TCGA) colon cancer and rectal cancer (COADREAD) database. Furthermore, the differential expression of HCAR3 and INLS5 was validated in clinical tumor samples by Real-time quantitative PCR analysis, western blotting analysis, and immunohistochemistry analysis. Finally, CRC cells over-expressing INSL5 were constructed and used for CCK8, cell cycle, and cell apoptosis validation assays in vitro.

Results
A total of 286 differentially expressed genes (DEGs) were screened, including 64 genes with increased expression and 143 genes with decreased expression in 2 CRC database, from which 10 key genes were identified: CXCL1, HCAR3, CXCL6, CXCL8, CXCL2, CXCL5, PPY, SST, INSL5, and NPY1R. Among these genes, HCAR3 and INSL5 had not previously been explored and were further verified in vitro.

Conclusions
HCAR3 expression was higher in CRC tissues and associated with better overall survival of CRC patients. INSL5 expression in normal tissue was higher than that in tumor tissue and its high expression was associated with a better prognosis for CRC. The overexpression of INSL5 significantly inhibited the proliferation and promoted the shearing of PARP of CRC cells. This integrated bioinformatics study presented 10 key hub genes associated with CRC. HCAR3 and INSL5 were expressed in tumor tissue and these were associated with poor survival and warrant further studies as potential therapeutic targets.

Abstract
Background
Maintaining sufficient health care workforce is a global priority to achieve universal health coverage. Therefore this study addresses the availability of physiotherapists in Brazil.

Objective
To describe secular trends of the physiotherapy workforce-to-population ratio in the Unified Health System, considering public and private sector and care level (primary, secondary, tertiary) in Brazil and its regions.

Method
Descriptive exploratory quantitative study based on secondary sources. All data related to the distribution of physiotherapists between August 2007 and September 2016 regarding facilities types, location and public and private sectors was obtained from the Brazilian National Registry of Health Care Facilities. Data related to the population of Brazil was extracted from Brazilian Institute of Geography and Statistics. The physiotherapy workforce-to-population ratio was calculated by the number of physiotherapists per 1000 population (public and private sector and care level) by ANOVA test. The distribution trends are represented on maps. Annual growth rates were estimated with Prais–Winsten linear regression models, with a significance level of 0.05, autocorrelation was checked by the Durbin–Watson test.

Results
The physiotherapists ratio in Brazil was 0.22/1000 population in 2007 and 0.41 in 2016, showing growth of 86%, with an increasing trend of 0.5% on an annual average. The public sector had the biggest physiotherapy workforce in the country in 2007 and 2016. The primary health care had the smallest physiotherapy workforce-to-population ratio (2007: p > 0.001 and 2016: p = 0.003), even though it had the largest growth trend in annual average (0.9% p > 0.001), followed by public and private tertiary health care sectors (0.8% p > 0.001). The workforce in secondary health care was bigger in the private sector than in the public sector (0.6% p > 0.001 vs. 0.2% p = 0.004). Overall, all regions had greater growth of physiotherapy workforce-to-population ratio in public primary and tertiary health care sectors, and private secondary health care sector, mainly the Southeast, South and Central-West regions.

Conclusion
Although the physiotherapy workforce in Brazil is relatively small, there was a trend towards growth with differences among care levels, and public and private sectors. The physiotherapy workforce-to-population ratio is bigger in the private secondary health care sector, followed by public tertiary, secondary and primary health care sectors. Sub-national regions show similar trends to the national estimates, with minor variations by region.
Identifying the content and context of pain within paediatric rheumatology healthcare professional curricula in the UK: a summative content analysis
Authors: Lee Rebecca Rachael , McDonagh Janet E. , Connelly Mark , Peters Sarah , Cordingley Lis 
Published: August 2021

Abstract
Background
The curriculum for professionals working in paediatric rheumatology should include pain but it is unclear to what extent this currently occurs. The aim of this study was to identify pain-related curriculum content and the context in which pain is presented in educational and training documentation for healthcare professionals in this clinical speciality.

Methods
Core curricula documents from UK based professional organisations were identified in partnership with healthcare professionals. Documents were analysed using a summative content analysis approach. Key pain terms were quantified and weighted frequencies were used to explore narrative pain themes. Latent content was interpreted qualitatively to explore the context within which pain terms were positioned.

Results
Nine curriculum documents were identified and analysed from doctors, nurses, physiotherapists and occupational therapists specialising in paediatric rheumatology. Pain themes represented a mean percentage of 1.51% of text across all documents. Pain was rarely presented in the context of both inflammatory and non-inflammatory condition types despite being a common feature of each. Musculoskeletal pain was portrayed simply as a ‘somatic’ symptom, rather than as a complex phenomenon involving biological and psychosocial processes. Content around the assessment and management of pain was vague and inexplicit.

Conclusion
Current educational and training documentation in paediatric rheumatology do not include core pain topics. Curricula for these healthcare professionals would benefit from updates in contemporary pain theories and examples of in-context, evidence-based pain practices. This should be a priority starting point for optimising patient pain care in paediatric musculoskeletal healthcare.
Golimumab in juvenile idiopathic arthritis-associated uveitis unresponsive to Adalimumab
Authors: Lanz Sofia , Seidel Gerald , Skrabl-Baumgartner Andrea 
Published: August 2021

Abstract
Objective
To assess the efficacy of golimumab (GLM) as a treatment option for juvenile idiopathic arthritis (JIA)-associated uveitis refractory to adalimumab (ADA).

Methods
Retrospective single-centre study including patients with JIA receiving GLM for active uveitis after failing ADA. JIA- and uveitis-related data, including intraocular inflammation, best-corrected visual acuity, corticosteroid-sparing potential, and ocular complications were evaluated at start of GLM treatment, at 1 month and 3 months, and every 3 months thereafter during GLM administration. We further investigated the association of response to GLM with primary and secondary failure of ADA treatment.

Results
Ten patients were studied, all female (17 affected eyes, mean age 14.3 + 6.7 yrs., mean follow-up 25.2 + 21.7 mos). Two patients were switched to GLM because of primary non-response to ADA. Eight were switched because of loss of response (LOR).
In 5 of the latter LOR was associated with neutralizing anti-ADA-antibodies. Response to GLM was observed in all 8 patients with LOR, while the 2 patients with primary non-response to ADA also did not respond to GLM. Three of the 8 responders experienced LOR. At the end of follow-up 4 of the 5 remaining responders had achieved complete response. One had achieved partial response.

Conclusion
GLM is an efficacious therapeutic option in patients who experience LOR to ADA. Our data indicate that patients without primary response to ADA should be rather switched to a biologic agent with a different mode of action instead of further blocking the TNF-alpha pathway.

AbstractBackgroundDue to their anti-inflammatory action, corticosteroids are the reference treatment for brain injuries and many inflammatory diseases. However, the benefits of acute corticotherapy are now being questioned, particularly in the case of acute peripheral vestibulopathies (APV), characterized by a vestibular syndrome composed of sustained spinning vertigo, spontaneous ocular nystagmus and oscillopsia, perceptual-cognitive, posturo-locomotor, and vegetative disorders. We assessed the effectiveness of acute corticotherapy, and the functional role of acute inflammation observed after sudden unilateral vestibular loss.MethodsWe used the rodent model of unilateral vestibular neurectomy, mimicking the syndrome observed in patients with APV. We treated the animals during the acute phase of the vestibular syndrome, either with placebo or methylprednisolone, an anti-inflammatory corticosteroid. At the cellular level, impacts of methylprednisolone on endogenous plasticity mechanisms were assessed through analysis of cell proliferation and survival, glial reactions, neuron’s membrane excitability, and stress marker. At the behavioral level, vestibular and posturo-locomotor functions’ recovery were assessed with appropriate qualitative and quantitative evaluations.ResultsWe observed that acute treatment with methylprednisolone significantly decreases glial reactions, cell proliferation and survival. In addition, stress and excitability markers were significantly impacted by the treatment. Besides, vestibular syndrome’s intensity was enhanced, and vestibular compensation delayed under acute methylprednisolone treatment.ConclusionsWe show here, for the first time, that acute anti-inflammatory treatment alters the expression of the adaptive plasticity mechanisms in the deafferented vestibular nuclei and generates enhanced and prolonged vestibular and postural deficits. These results strongly suggest a beneficial role for acute endogenous neuroinflammation in vestibular compensation. They open the way to a change in dogma for the treatment and therapeutic management of vestibular patients.

Published: August 2021

Abstract
Background
Intracerebral hemorrhage (ICH) results in a cascade of inflammatory cell activation with recruitment of peripheral leukocytes to the brain parenchyma and surrounding the hematoma. We hypothesized that in patients with ICH and intraventricular hemorrhage (IVH), a robust cerebrospinal fluid (CSF) inflammatory response occurs with leukocyte subtypes being affected by alteplase treatment and contributing to outcomes.

Methods
Serum and CSF cell counts from patients in the phase 3 Clot Lysis: Evaluating Accelerated Resolution of Intraventricular Hemorrhage (CLEAR III) trial were analyzed. CSF leukocytes were corrected for the presence of red blood cells. Trends in cell counts were plotted chronologically. Associations were evaluated between serum and CSF leukocyte subtypes and adjudicated functional outcome (modified Rankin Scale; mRS) at 30 and 180 days and bacterial infection according to treatment with intraventricular alteplase versus saline.

Results
A total of 279 and 292 patients had ≥3 differential cell counts from serum and CSF, respectively. CSF leukocyte subtypes evolved during IVH resolution with a significantly augmented inflammatory response for all subtypes in alteplase- compared to saline-treated patients. CSF leukocyte subtypes were not associated with detrimental effect on functional outcomes in the full cohort, but all were associated with poor 30-day outcome in saline-treated patients with IVH volume ≥20 mL. Higher serum lymphocytes were associated with good functional outcomes (mRS 0–3) in the entire cohort and saline-treated but not alteplase-treated group. Conversely, increased serum neutrophil-to-lymphocyte ratio (NLR) in the entire cohort and saline group was associated with worse functional outcomes. Higher median serum lymphocytes were associated with the absence of infection at 7 days.

Conclusions
Aseptic CSF inflammation after IVH involves all leukocyte subtypes. Serum lymphocytes may be associated with better outcomes by mitigating infection. Alteplase augments the inflammatory response without affecting outcomes.
Soluble tumor necrosis factor-alpha-induced hyperexcitability contributes to retinal ganglion cell apoptosis by enhancing Nav1.6 in experimental glaucoma

Published: August 2021

Abstract
Background
Neuroinflammation plays an important role in the pathogenesis of glaucoma. Tumor necrosis factor-alpha (TNF-α) is a major pro-inflammatory cytokine released from activated retinal glial cells in glaucoma. Here, we investigated how TNF-α induces retinal ganglion cell (RGC) hyperexcitability and injury.

Methods
Whole-cell patch-clamp techniques were performed to explore changes in spontaneous firing and evoked action potentials, and Na+ currents in RGCs. Both intravitreal injection of TNF-α and chronic ocular hypertension (COH) models were used. Western blotting, immunofluorescence, quantitative real-time polymerase chain reaction (q-PCR), and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) techniques were employed to investigate the molecular mechanisms of TNF-α effects on RGCs.

Results
Intravitreal injection of soluble TNF-α significantly increased the spontaneous firing frequencies of RGCs in retinal slices. When the synaptic transmissions were blocked, more than 90% of RGCs still showed spontaneous firing; both the percentage of cells and firing frequency were higher than the controls. Furthermore, the frequency of evoked action potentials was also higher than the controls. Co-injection of the TNF-α receptor 1 (TNFR1) inhibitor R7050 eliminated the TNF-α-induced effects, suggesting that TNF-α may directly act on RGCs to induce cell hyperexcitability through activating TNFR1. In RGCs acutely isolated from TNF-α-injected retinas, Na+ current densities were upregulated. Perfusing TNF-α in RGCs of normal rats mimicked this effect, and the activation curve of Na+ currents shifted toward hyperpolarization direction, which was mediated through p38 MAPK and STAT3 signaling pathways. Further analysis revealed that TNF-α selectively upregulated Nav1.6 subtype of Na+ currents in RGCs. Similar to observations in retinas of rats with COH, intravitreal injection of TNF-α upregulated the expression of Nav1.6 proteins in both total cell and membrane components, which was reversed by the NF-κB inhibitor BAY 11-7082. Inhibition of TNFR1 blocked TNF-α-induced RGC apoptosis.

Conclusions
TNF-α/TNFR1 signaling induces RGC hyperexcitability by selectively upregulating Nav1.6 Na+ channels, thus contributing to RGC apoptosis in glaucoma.
Markov modelling of viral load adjusting for CD4 orthogonal variable and multivariate conditional autoregressive mapping of the HIV immunological outcomes among ART patients in Zimbabwe
Authors: Matsena Zingoni Zvifadzo , Chirwa Tobias F. , Todd Jim , Musenge Eustasius 
Published: August 2021

Abstract
Background
This study aimed to jointly model HIV disease progression patterns based on viral load (VL) among adult ART patients adjusting for the time-varying “incremental transients states” variable, and the CD4 cell counts orthogonal variable in a single 5-stage time-homogenous multistate Markov model. We further jointly mapped the relative risks of HIV disease progression outcomes (detectable VL (VL ≥ 50copies/uL) and immune deterioration (CD4 < 350cells/uL) at the last observed visit) conditional not to have died or become loss to follow-up (LTFU).

Methods
Secondary data analysis of individual-level patients on ART was performed. Adjusted transition intensities, hazard ratios (HR) and regression coefficients were estimated from the joint multistate model of VL and CD4 cell counts. The mortality and LTFU transition rates defined the extent of patients’ retention in care. Joint mapping of HIV disease progression outcomes after ART initiation was done using the Bayesian intrinsic Multivariate Conditional Autoregressive prior model.

Results
The viral rebound from the undetectable state was 1.78times more likely compared to viral suppression among patients with VL ranging from 50-1000copies/uL. Patients with CD4 cell counts lower than expected had a higher risk of viral increase above 1000copies/uL and death if their VL was above 1000copies/uL (state 2 to 3 (λ23): HR = 1.83 and (λ34): HR = 1.42 respectively). Regarding the time-varying effects of CD4 cell counts on the VL transition rates, as the VL increased, (λ12 and λ23) the transition rates increased with a decrease in the CD4 cell counts over time. Regardless of the individual’s VL, the transition rates to become LTFU decreased with a decrease in CD4 cell counts. We observed a strong shared geographical pattern of 66% spatial correlation between the relative risks of detectable VL and immune deterioration after ART initiation, mainly in Matabeleland North.

Conclusion
With high rates of viral rebound, interventions which encourage ART adherence and continual educational support on the barriers to ART uptake are crucial to achieve and sustain viral suppression to undetectable levels. Area-specific interventions which focus on early ART screening through self-testing, behavioural change campaigns and social support strategies should be strengthened in heavily burdened regions to sustain the undetectable VL. Sustaining undetectable VL lowers HIV transmission in the general population and this is a step towards achieving zero HIV incidences by 2030.

Published: August 2021

Abstract
Background
Recent data suggest the importance of non-neutralizing antibodies (nnAbs) in the development of vaccines against HIV-1 because two types of nnAbs that recognize the coreceptor binding site (CoRBS) and the C1C2 region mediate antibody-dependent cellular-cytotoxicity (ADCC) against HIV-1-infected cells. However, many studies have been conducted with nnAbs obtained from subtype B-infected individuals, with few studies in patients with non-subtype B infections.

Results
We isolated a monoclonal antibody 1E5 from a CRF02_AG-infected individual and constructed two forms of antibody with constant regions of IgG1 or IgG3. The epitope of 1E5 belongs to the C1C2 of gp120, and 1E5 binds to 27 out of 35 strains (77 %) across the subtypes. The 1E5 showed strong ADCC activity, especially in the form of IgG3 in the presence of small CD4-mimetic compounds (CD4mc) and 4E9C (anti-CoRBS antibody), but did not show any neutralizing activity even against the isolates with strong binding activities. The enhancement in the binding of A32, anti-C1C2 antibody isolated from a patient with subtype B infection, was observed in the presence of 1E5 and the combination of 1E5, A32 and 4E9C mediated a strong ADCC activity.

Conclusions
These results suggest that anti-C1C2 antibodies that are induced in patients with different HIV-1 subtype infections have common functional modality and may have unexpected interactions. These data may have implications for vaccine development against HIV-1.
