Published: November 2021

Abstract
Background
Online education has been used as an adjunct modality for teaching and it attracts attention in recent years as many medical students can not accomplish their clerkship in the hospital due to COVID-19 pandemic. This study aims to collect the articles related to online surgical education for medical students, and to analyze the effectiveness of online education and the perceptions of the medical students.

Method
We performed a systemic literature search in PubMed, MEDLINE, EMBASE, ERIC and Cochrane library. Keywords used for searching included “medical student”, “online education”, “online teaching”, “online learning”, “distance learning”, “electronic learning”, “virtual learning” and “surgical”. Medical education research study quality instrument (MERSQI) was used for the evaluation of the quality of the searched articles.

Results
From 1240 studies retrieved from the databases, 13 articles were included in this study after screening. The publication year was from 2007 to 2021. The mean MERSQI score of the 13 searched articles was 12.5 +/− 1.7 (range 10.0-14.5). There were totally 2023 medical students who attended online surgical curriculum. By online course, improvement of understanding and knowledge on the studied topics could be reached. The confidence in patient encounters could be improved by online curriculum with sharing experiences, discussing, and role playing. However, students felt concentration was poor during online course. Medical students studying through video platform could get better test scores than those studying with textbooks. Regarding basic surgical skills, online teaching of suturing and knot-tying could be possible and was appreciated by the students who could practice away from the hospital and get feedbacks by instructors through online environment. The scores for the clinical competence assessment for incision, suturing and knot-tying were found to be no significant difference between the online teaching group and face-to-face teaching group.

Conclusion
Online surgical curriculum for medical students is not easy but inevitable in the era of COVID-19 pandemic. Although online course is not the same as physical course, there are some efforts which could be tried to increase the effectiveness. Basic surgical skills could also be taught effectively through online platform. Even if the COVID-19 pandemic is over in the future, online curriculum could still be a helpful adjunct for surgical education.

Published: November 2021

Abstract
Background
Immunopreventable diseases are a public health reality in Brazil and worldwide, a reality that is not exclusive to children, but affects the adult population.

Objectives
Discriminating the total costs of hospitalizations from immunopreventable diseases in the population aged 20 to 59 years.

Methods
A population, observational, descriptive, retrospective study was conducted with secondary information from DATASUS to discriminate the hospitalizations associated with immunopreventable diseases in Brazil and their care costs, within the Scope of the SUS, between 2008 and 2018, in the economically active population (20 to 59 years).

Results
It was analyzed 127,746 hospitalizations for immunopreventable diseases, (27.92% of all hospitalizations) were observed in the adult population, totaled R$115,682,097.54 (29.72% of the total costs). Of this population studied, 51.48% were registered as male; 66.74% were associated with influenza disease; 16.05% to chickenpox/herpes zoster infection and 7.55% to acute hepatitis B infections. The trend analysis of the time series of hospitalizations in this population showed a stationary trend.

Conclusions
The 127,746 hospitalizations could be avoided with immunization, and 127,746 workers who could be working and not hospitalized. There were also R$115,682,097.54 that could be invested in other public health needs, which became necessary for the treatment of preventable diseases.

Abstract
Background
This article presents the first detailed analysis of the prevalence and disability burden of Guillain–Barré syndrome (GBS) from 1990 to 2019 by cause, age, sex, and Socio-demographic Index (SDI) in 204 countries and territories.

Methods
Data from the Global Burden of Diseases Study (GBD) 2019 were used. GBD 2019 modelled the prevalence of GBS using hospital and claims data. Years lived with disability (YLDs) were estimated as the product of the GBS prevalence and the disability weight. This article also reported proportions in the age-standardised prevalence rate that were due to six underlying causes of GBS.

Results
In 2019, there were 150,095 [95% uncertainty intervals (UI) 119,924 to 188,309] total cases of GBS worldwide, which resulted in 44,407 (95% UI 28,016 to 64,777) YLDs. Globally, there was a 6.4% (95% UI 3.6 to 9.5) increase in the age-standardised prevalence of GBS per 100,000 population between 1990 and 2019. High-income Asia Pacific [1.9 (95% UI: 1.5 to 2.4)] and East Asia [0.8 (95% UI: 0.6 to 1.0)] had the highest and lowest age-standardised prevalence rates (per 100,000), respectively, in 2019. Nationally, Japan [6.4 (95% UI: 5.3 to 7.7)] and China [0.8 (95% UI: 0.6 to 1.0)] had the highest and lowest age-standardised prevalence rates (per 100,000). The age-standardised burden of GBS increased with increasing age and was higher in males in all age groups. Furthermore, the age-standardised prevalence of GBS (per 100,000) had a positive association with the level of development, as measured by SDI, although this association was not strong. Upper respiratory infections and unknown causes accounted for the highest proportions of underlying causes.

Conclusions
Globally, the prevalence of GBS continues to increase. Geographical differences and strategies aimed at preventing infectious diseases should be considered in future health policy planning and decision-making processes. This study had several limitations, such as using the same disability weight for all causes and a reliance on hospital- and self-reported data, which should be addressed in future research.

AbstractObjectivesAccelerated atherosclerosis in older HIV-infected patients has been attributed to persistent immune activation and high burden cytomegalovirus (CMV), as demonstrated in transplant recipients and the general population. Here we assess CMV and inflammatory markers linked with vascular health in young adult patients treated in Indonesia.Study designHIV-infected adults (n = 32) were examined when they began antiretroviral therapy (ART) with < 200 CD4 T-cells/µl (V0) and after 60 months (V60). Age-matched healthy controls (HC, n = 32) were assessed once.MethodsFlow Mediated Dilatation (FMD) was assessed by ultrasound on brachial arteries at V60 and in HC. Plasma markers of immune activation and endothelial activation, and CMV antibodies (lysate, gB, IE-1) were assessed in all samples. Results were assessed using bivariate (non-parametric) and multivariable analyses.ResultsLevels of inflammatory biomarkers and CMV antibodies declined on ART, but the antibodies remained higher than in HC. FMD values were similar in patients and HC at V60. In HIV patients, levels of CMV lysate antibody correlated inversely (r = − 0.37) with FMD. The optimal model predicting lower FMD values (adjusted R2 = 0.214, p = 0.012) included CMV lysate antibodies and chondroitin sulphate. In HC, levels of sTNFR correlated inversely with FMD (r = − 0.41) and remained as a risk factor in the optimal multivariable model, with CMV glycoprotein-B (gB) antibody predicting a healthier FMD (adjusted R2 = 0.248, p = 0.013).ConclusionsHigher levels CMV antibodies optimally predict vascular health measured by FMD in HIV patients. However in healthy controls, sTNFR marks risk and CMV gB antibody may be protective.

Abstract
Background
Diffuse large B-cell lymphoma (DLBCL) comprises at least two main biologically distinct entities: germinal center B-cell (GCB) and activated B-cell (ABC) subtype. Albeit sharing common lesions, GCB and ABC DLBCL present subtype-specific oncogenic pathway perturbations. ABC DLBCL is typically characterized by a constitutively active NF-kB. However, the latter is seen in also 30% of GCB DLBCL. Another recurrent lesion in DLBCL is an 11q24.3 gain, associated with the overexpression of two ETS transcription factors, ETS1 and FLI1. Here, we showed that FLI1 is more expressed in GCB than ABC DLBCL and we characterized its transcriptional network.

Methods
Gene expression data were obtained from public datasets GSE98588, phs001444.v2.p1, GSE95013 and GSE10846. ChIP-Seq for FLI1 paired with transcriptome analysis (RNA-Seq) after FLI1 silencing (siRNAs) was performed. Sequencing was carried out using the NextSeq 500 (Illumina). Detection of peaks was done using HOMER (v2.6); differential expressed genes were identified using moderated t-test (limma R-package) and functionally annotated with g:Profiler. ChIP-Seq and RNA-Seq data from GCB DLBCL cell lines after FLI1 downregulation were integrated to identify putative direct targets of FLI1.

Results
Analysis of clinical DLBCL specimens showed that FLI1 gene was more frequently expressed at higher levels in GCB than in ABC DLBCL and its protein levels were higher in GCB than in ABC DLBCL cell lines. Genes negatively regulated by FLI1 included tumor suppressor genes involved in negative regulation of cell cycle and hypoxia. Among positively regulated targets of FLI1, we found genes annotated for immune response, MYC targets, NF-κB and BCR signaling and NOTCH pathway genes. Of note, direct targets of FLI1 overlapped with genes regulated by ETS1, the other transcription factor gained at the 11q24.3 locus in DLBCL, suggesting a functional convergence within the ETS family. Positive targets of FLI1 included the NF-κB-associated ASB2 a putative essential gene for DLBCL cell survival. ASB2 gene downregulation was toxic in GCB DLBCL cell lines and induced NF-κB inhibition via downregulation of RelB and increased IκBα. Additionally, downregulation of FLI1, but not ASB2, caused reduction of NF-κB1 and RelA protein levels.

Conclusions
We conclude that FLI1 directly regulates a network of biologically crucial genes and processes in GCB DLBCL. FLI1 regulates both the classical NF-κB pathway at the transcriptional level, and the alternative NF-κB pathway, via ASB2. FLI1 and ASB2 inhibition represents a potential novel therapeutic approach for GCB DLBCL.

Abstract
Background
Raising children in new social and cultural contexts can be challenging for parents. In order to help parents address these challenges, the Norwegian government has instituted a policy of mandatory parent training for families who settle in Norway as refugees. The Incredible Years (IY) and The International Child Development Programme (ICDP) have been widely adopted throughout Norway. They have similar aims: to improve parenting through positive parenting practices and development of attachment behaviors. We will evaluate the use of these programs and a measurement feedback system (MFS) to give regular feedback to interventionists about parents’ progress during the course of the parenting intervention.

Methods
The study is a mixed method, randomized factorial design aimed at evaluating the effect of parenting interventions and the use of feedback to address parental stress, child behavior, resilience, and parents’ mental health. Factor 1 is based on random assignment to one of the parenting interventions IY or ICDP. The parenting interventions are delivered over 15 weeks (IY) or 12 weeks (ICDP) in group-based settings. Factor 2 is based on random assignment of the parenting groups to the (a) with MFS or (b) without MFS condition. The MFS is answered weekly via a phone app, MittEcho, and results are sent to group leaders in the MFS condition. Additionally, the study explores the experiences of families settling in a new cultural context and participating with parenting programs via qualitative interviews. Participants will be recruited from a population of parents with children between the age of 6 and 12 years who settled in Norway as refugees within the previous 9 years. The target sample size is N = 360; n (IY) = 180, n (ICDP) = 180 families. This study is a collaboration between first-line, municipal services; their national governing agencies; family representatives; and a national network of research organizations.

Discussion
This study endeavors to provide information about what helps families with refugee background integrate successfully into new cultural contexts with different laws, norms, and expectations. Whether or not these interventions can help to normalize this experience, reduce stress, and provide parents with new tools to improve their parenting and the lives of their children are important questions which we address. These findings can lead to the further establishment of evidence-based practices in Norway.

Shrinkage of a pituitary metastasis of melanoma induced by pembrolizumab: a case report
Authors: Giuffrida Giuseppe , Ferraù Francesco , Alessi Ylenia , Cannavò Salvatore 
Published: November 2021

Abstract
Background
Pituitary metastases are rare, often deriving from lung or breast cancer owing to the upper vena cava proximity. Pituitary metastases can manifest with signs and symptoms of pituitary tumors, consequent to mass effect (headache, visual impairment) and/or hormonal alterations (hyperprolactinemia, hypopituitarism, and diabetes insipidus). Immune checkpoint inhibitors burst immunity against tumors, significantly increasing patients’ survival, but their autoimmune side effects frequently involve the skin, the gastrointestinal tract, and the endocrine glands (pituitary, thyroid, pancreas).

Case presentation
A 77-year-old Caucasian man had undergone trans-nasal sphenoidal surgery for a nonsecreting pituitary macroadenoma in 2001, without remnant or endocrine deficits. In 2016, he was operated for a shoulder melanoma. In February 2018, imaging evaluation demonstrated metastases in lung, liver, and femur. Therefore, treatment with pembrolizumab (anti-programmed death 1) was scheduled in May 2018, but, before starting this therapy, a brain computed tomography performed for a sudden loss of consciousness detected a sellar mass of 17 × 12 mm, which extended to the pituitary stalk and compressed the optic chiasma. Focused magnetic resonance imaging confirmed the size and characteristics of the lesion, while emergency evaluation of the hormonal profile demonstrated an impairment of adrenal and thyroid function. The pituitary lesion demonstrated a remarkable shrinkage (8 × 6 mm), which was confirmed by subsequent imaging evaluations.

Conclusions
This is the first case reporting on effectiveness of immune checkpoint inhibitors in a patient with pituitary metastasis from a melanoma.
Mariela Muñoz

Published: November 2021

Abstract
Mariela Muñoz became the first transsexual widely socially recognized as a mother in Argentina. She emerged as a leading figure during her struggle to recover legal custody of three of her children, which had been previously annulled by a judge. Moreover, in 1997 she became the first transsexual recognized as a woman by the state. This text analyzes the making of Mariela Muñoz's motherhood repertoires to redefine political, social, and intimate citizenship. It argues that her politics were paradoxical, in that she appealed to traditional meanings of womanhood such as fulfilment through motherhood and the duty of care for others. On the other hand, these uses of key cultural symbols displaced the imagined margins for travestis and transexuales and helped her enjoy popular support.

Objective:The use of regorafenib in recurrent glioblastoma patients has been recently approved by the Italian Medicines Agency (AIFA) and added to the National Comprehensive Cancer Network (NCCN) 2020 guidelines as a preferred regimen. Given its complex effects at the molecular level, the most appropriate imaging tools to assess early response to treatment is still a matter of debate. Diffusion-weighted imaging and O-(2-18F-fluoroethyl)-L-tyrosine positron emission tomography ([18F]FET PET) are promising methodologies providing additional information to the currently used RANO criteria. The aim of this study was to evaluate the variations in diffusion-weighted imaging/apparent diffusion coefficient (ADC) and [18F]FET PET-derived parameters in patients who underwent PET/MR at both baseline and after starting regorafenib.Methods:We retrospectively reviewed 16 consecutive GBM patients who underwent [18F]FET PET/MR before and after two cycles of regorafenib. Patients were sorted into stable (SD) or progressive disease (PD) categories in accordance with RANO criteria. We were also able to analyze four SD patients who underwent a third PET/MR after another four cycles of regorafenib. [18F]FET uptake greater than 1.6 times the mean background activity was used to define an area to be superimposed on an ADC map at baseline and after treatment. Several metrics were then derived and compared. Log-rank test was applied for overall survival analysis.Results:Percentage difference in FET volumes correlates with the corresponding percentage difference in ADC (R = 0.54). Patients with a twofold increase in FET after regorafenib showed a significantly higher increase in ADC pathological volume than the remaining subjects (p = 0.0023). Kaplan–Meier analysis, performed to compare the performance in overall survival prediction, revealed that the percentage variations of FET- and ADC-derived metrics performed at least as well as RANO criteria (p = 0.02, p = 0.024 and p = 0.04 respectively) and in some cases even better. TBR Max and TBR mean are not able to accurately predict overall survival.ConclusionIn recurrent glioblastoma patients treated with regorafenib, [18F]FET and ADC metrics, are able to predict overall survival and being obtained from completely different measures as compared to RANO, could serve as semi-quantitative independent biomarkers of response to treatment.Advances in knowledgeSimultaneous evaluation of [18F]FET and ADC metrics using PET/MR allows an early and reliable identification of response to treatment and predict overall survival.

Authors: Tyyger Marcus , Bhaumik Suchandana , Nix Michael , Currie Stuart , Nallathambi Chandran , Speight Richard , Al-Qaisieh Bashar , Murray Louise 
Published: November 2021

Objectives: Glioblastoma (GBM) radiotherapy (RT) target delineation requires MRI, ideally concurrent with CT simulation (pre-RT MRI). Due to limited MRI availability, <72 h post-surgery MRI is commonly used instead. Whilst previous investigations assessed volumetric differences between post-surgical and pre-RT delineations, dosimetric impact remains unknown. We quantify volumetric and dosimetric impact of using post-surgical MRI for GBM target delineation. Methods: Gross tumour volumes (GTVs) for five GBM patients receiving chemo-RT with post-surgical and pre-RT MRIs were delineated by three independent observers. Planning target volumes (PTVs) and RT plans were generated for each GTV. Volumetric and dosimetric differences were assessed through: absolute volumes, volume-distance histograms and dose-volume histogram statistics. Results: Post-surgical MRI delineations had significantly (p < 0.05) larger GTV and PTV volumes (median 16.7 and 64.4 cm3, respectively). Post-surgical RT plans, applied to pre-RT delineations, had significantly decreased (p < 0.01) median PTV doses (ΔD99% = −8.1 Gy and ΔD95% = −2.0 Gy). Median organ-at-risk (OAR) dose increases (brainstem ΔD5% =+0.8, normal brain mean dose =+2.9 and normal brain ΔD10% = 5.3 Gy) were observed. Conclusion: Post-surgical MRI delineation significantly impacted RT planning, with larger normal-appearing tissue volumes irradiated and increased OAR doses, despite a reduced coverage of the pre-RT defined target. Advances in knowledge: We believe this is the first investigation assessing the dosimetric impact of using post-surgical MRI for GBM target delineation. It highlights the potential of significantly degraded RT plans, showing the clinical need for dedicated MRI for GBM RT.
