Maoto, a traditional Japanese medicine (Kampo), is widely used to treat upper respiratory tract infections, including influenza virus infection. Although maoto is known to inhibit pro-inflammatory responses in a rodent model of acute inflammation, its underlying mechanism remains to be determined. In this study, we investigated the involvement of immune responses and noradrenergic function in the inhibitory action of maoto. In a mouse model of polyI:C-induced acute inflammation, maoto was administered orally in conjunction with intraperitoneal injection of PolyI:C (6 mg/kg), and blood was collected after 2 h for measurement of plasma cytokines by ELISA. Maoto significantly decreased PolyI:C-induced TNF-α levels and increased IL-10 production. Neither pretreatment with IL-10 neutralizing antibodies nor T-cell deficiency using nude mice modified the inhibitory effect of maoto, indicating that the anti-inflammatory effects of maoto are independent of IL-10 and T cells. Furthermore, the inhibitory effects of maoto on PolyI:C-induced TNF-α production were not observed in ex vivo splenocytes, suggesting that maoto does not act directly on inflammatory cells. Lastly, pretreatment with a ß-adrenergic receptor antagonist partially cancelled the anti-inflammatory effects of maoto. Collectively, these results suggest that maoto mediates its anti-inflammatory effects via ß-adrenergic receptors in vivo.

Gastric cancer (GC)-derived cell lines were generally used in basic cancer research and drug screening. However, it is always concerned about the difference between cultured cells and primary tumor by oncologists. To address this question, we compared differentially expressed genes (DEGs) in primary cancers, healthy tissues, and cell lines both in vitro and in silico. Seven reported genes with decreased expression in GCs by DNA methylation were analyzed in our cohort studies and experimentally validation. Selected datasets from TCGA (The Cancer Genome Atlas), CCLE (The Broad Institute Cancer Cell Line Encyclopedia), and GTEx (The Genotype-Tissue Expression project) were used to represent GCs, GC-derived cell lines, and healthy tissues respectively in the in silico analysis. Thirty gastric tissues together with six cell lines were used for validations. Unexpectedly, we experimentally found that reported cancer-related downregulated genes were only found in cancer cell lines but not in biopsies. The unchanged gene expressions in primary GCs were generally consistent with our cohort study, using information from cancerous (TCGA) and healthy tissues (GETx). Substantial differences were also found between DEGs of cancer tissues (TGCA)/ healthy tissues (GTEx) pair and cell lines (CCLE)/ healthy tissues (GTEx) pair, which confirmed the significant differences between primary cancer and cancer cell lines. Moreover, elevated expression of YWHAQ (14-3-3 δ) and THBS1 were observed in the GC biopsies, which might be potential biomarkers for GC diagnosis, considering the increased YWHAQ and THBS1 associated with poor survival rates in gastric cancer patients. In sum, it is suggested that cautions should be taken when using GC cell lines to study genes that show great differences between cell lines and tissues.

Soluble molecules of programmed death ligand 1 (sPD-L1) are known to modulate T-cell depletion, an important mechanism of hepatitis B virus (HBV) persistence and liver disease progression. In addition, PD-L1 polymorphisms in the 3'-UTR can influence PD-L1 expression and have been associated with cancer risk, although not definitively. The purpose of this study was to investigate the association of PD-L1 polymorphisms and circulating levels of sPD-L1 in HBV infection and live disease progression. In this study, five hundred fifty-one HBV infected patients of the three clinically well-defined subgroups chronic hepatitis B (CHB, n = 186), liver cirrhosis (LC, n = 142) and hepatocellular carcinoma (HCC, n = 223) and 240 healthy individuals (HC) were enrolled. PD-L1 polymorphisms (rs2297136 and rs4143815) were genotyped by in-house validated ARMS assays. Logistic regression models were applied in order to determine the association of PD-L1 polymorphisms with HBV infection as well as with progression of related liver diseases. Plasma sPD-L1 levels were quantified by ELISA assays. The PD-L1 rs2297136 AA genotype was associated with HBV infection susceptibility (HBV vs. HC: OR = 1.6; 95%CI = 1.1-2.3; p = 0.0087) and disease progression (LC vs. CHB: OR = 1.8; 95%CI = 1.1-2.9; p = 0.018). Whereas, the rs2297136 GG genotype was a protective factor for HCC development. Plasma sPD-L1 levels were significantly high in HBV patients (p < 0.0001) and higher in the LC followed by CHB and HCC groups. High sPD-L1 levels correlated with increased liver enzymes and with advanced liver disease progression (Child-pugh C > B > A, p < 0.0001) and BCLC classification (BCLC D > C > B > A, p = 0.031). We could, for the first time, conclude that PD-L1 rs2297136 polymorphism and plasma sPD-L1 protein levels associate with HBV infection and HBV-related liver disease progression.

Resumen Objetivo: Describir la supervivencia a siete años y los principales factores asociados a esta, en las personas con VIH que fueron atendidas en el sistema de salud colombiano entre 2011 a 2018. Métodos: Análisis de supervivencia de una cohorte de 64 039 personas diagnosticadas con VIH en Colombia. Se aplicó el método de Kaplan-Meier para estimar la probabilidad de supervivencia a partir de la fecha del diagnóstico. Se ajustó un modelo de supervivencia paramétrico flexible de Royston Parmar. Resultados: La estimación de la supervivencia global a 7 años fue de 94,8% (IC 95%: 94,5-95,2). El mayor riesgo de muerte se presentó en los hombres (HR: 1,2; IC 95%: 1,1-1,4; p: 0,010); en personas ≥50 años de edad (HR: 3,1; IC 95%: 1,6-6,3; p: 0,002); en el régimen subsidiado (HR: 2,2; IC 95%: 1,9-2,5; p: <0,001); en la etapa sida (HR: 2,8; IC 95%: 2,1-3,7; p: <0,001); en quienes presentaron la última carga viral detectable (HR: 7,1; IC 95%: 6,0-8,3; p: <0,001); y en quienes mostraron conteo de linfocitos T CD4+ <350 células/μL (HR: 1,9; IC 95%: 1,4-2,4; p: <0,001). Conclusión: La probabilidad de la supervivencia de las personas que viven con VIH aumenta al ser diagnosticados en edades jóvenes, en quienes presenten un recuento de linfocitos T CD4+ ≥350 células/μL, una carga viral indetectable (< 50 copias/mL) y no se encuentren en etapa sida.

Summary Objective: to describe the seven-year survival and predictors of mortality among people with HIV who were treated in the Colombian health system between 2011 and 2018. Methods: 64 039 people diagnosed with HIV in Colombia were included. Kaplan-Meier analysis estimated the probability of survival from the date of diagnosis. A Royston Parmar flexible parametric survival model was fitted. Results: The overall survival at 7 years was 94.8% (95% CI: 94.5-95.2). Survival was related to sex (men, HR: 1.2; 95% CI: 1.1-1.4; p: 0.010); people ≥50 years of age (HR: 3.1; 95% CI: 1.6-6.3; p: 0.002); subsidized regime (HR: 2.2; 95% CI: 1.9-2.5; p: <0.001); AIDS stage (HR: 2.8; 95% CI: 2.1-3.7; p: <0.001); a detectable viral load (HR: 7.1; 95% CI: 6.0-8.3; p: <0.001); and a CD4+ Lymphocyte count <350 cells/μL (HR: 1.9; 95% CI: 1.4-2.4; p: <0.001). Conclusion: The probability of survival of people living with HIV increases when they are diagnosed at a young age, in those with a CD4+ T Lymphocyte count ≥350 cells/μL, an undetectable viral load (<50 copies/mL) and are not in the AIDS stage.

Resumen Objetivo: Describir la proporción, características clínicas, demográficas y programáticas de casos fatales de coinfección TB/VIH de Cali-Colombia, en 2017. Material y Método: Estudio de corte transversal, con información de las bases de datos del programa de tuberculosis, las historias clínicas y unidades de análisis de mortalidad disponibles. Resultados: Se depuraron 257 casos fatales por TB, el 24,5% (63/257) falleció con coinfección TB/VIH. La mediana de edad fue 43 años (Rango Intercuartílico: 30-52), 73% (46/63) eran hombres, 76,2% (48/63) no pertenecían al régimen contributivo, 28,6% eran habitantes de calle. 81,2% (39/48) eran casos nuevos de TB, 76,6% (37/47), inició tratamiento; al 74,6% (47/63) se les realizó unidad de análisis de mortalidad. La presentación pulmonar fue frecuente (75,9%-44/58), en 60% de los registros se observó desnutrición (Índice de Masa Corporal <20), en 39,7% (25/63) dependencia al alcohol, tabaco o farmacodependencia. Conclusiones: La mortalidad asociada a TB/VIH es prevenible, pero en 2017 representó la cuarta parte de la mortalidad por TB en Cali. Hombres adultos con condiciones de vulnerabilidad social, diagnosticados en estados avanzados de enfermedad, fueron blanco de fatalidad. Mejorar los sistemas de información e integrar los programas de TB/VIH, deben ser estrategias prioritarias para la salud pública en Colombia.

Abstract Objective: To describe the proportion, clinical, demographic and programmatic characteristics of fatal cases of TB/HIV coinfection from Cali-Colombia, in 2017. Material and Method: Cross-sectional study, with information from the TB program databases, clinical records and mortality analysis units available. Results: 257 TB fatal cases were cleared in Cali in 2017, 24.5% (63/257) of these died with TB/HIV coinfection. The median age was 43 years (Interquartile Range: 30-52), 73% (46/63) were men, 76.2% (48/63) did not belong to the contributory health regimen, 28.6% were homeless. 81.2% (39/48) were new TB cases, 76.6% (37/47) started treatment; 74.6% (47/63) had mortality analysis register. Pulmonary presentation was frequent (75.9% -44 / 58), in 60% of the registries malnutrition was observed (Body Mass Index <20), in 39.7% (25/63), dependence on alcohol, tobacco or drug dependence was registered. Conclusions: Mortality associated with TB/HIV is preventable, but in 2017 it represented a quarter of the TB mortality in Cali. Adult men with conditions of social vulnerability, diagnosed in advanced stages of disease, were fatally targeted. Improving information systems and integrating TB/HIV programs should be priority strategies for public health in Colombia.

Aim: Evaluation of the reliability of 3D computed tomography (3D-CT) in the diagnosis of mandibular fractures. Methods: A cross-sectional, quantitative and qualitative study was carried out, through the application of a questionnaire for 70 professionals in the area of Oral and Maxillofacial Surgery and Radiology. 3D-CT images of mandibular fractures were delivered to the interviewees along with a questionnaire. Participants answered about the number of traces, the region and the type of fracture. The correct diagnosis, that is, the expected answer, was based on the reports of a specialist in oral and maxillofacial radiology after viewing the images in the axial, sagittal and coronal sections. The resulting data from the interviewees was compared with the expected answer and then, the data was analyzed statistically. Results: In the sample 56.9% were between 22 and 30 years old, 52.8% were oral and maxillofacial surgeons (OMF), 34.7% were residents in OMF surgery and 12.5% OMF radiologists. Each professional answered 15 questions (related to five patients) and 50.8% of the total of these was answered correctly. Specialists in Oral and Maxillofacial Surgery and Traumatology correctly answered 53.9%. Interviewees with experience between 6 and 10 years correctly answered 58.2%. In identifying fracture traces, 46.1% of the questions were answered correctly. In terms of location, 5.6% of interviewees answered wrongly while 14.2% answered wrongly regarding classification. Conclusion: 3D computed tomography did not prove to be a reliable image for diagnosing mandibular fractures when used alone. This made necessary an association with axial, sagittal and coronal tomographic sections

Aim: To evaluate the prevalence and predisposing factors for hypomineralization of second molars in children in primary dentition. Methods: A questionnaire was applied to parents to analyze predisposing factors and to assist in the diagnosis of hypomineralization in children between 2 and 6 years old, followed by an intraoral examination based on indices of non-fluorotic enamel defects in the primary dentition, according to the "Modified Index DDE" to determine demarcated opacity and HSPM presence / severity index to assess hypomineralization. Children from public and private schools were dived into two groups: if they presented HSPM-Group 1 (G1) and if they did not have HSPM-Control group (CG). Results: The most frequent predisposing factors associated with the child were Illness in the first year of life (X2= 6.49; p=0.01) and antibiotic use in the first year of life (X2= 41.82; p= 0.01). The factors associated with the mother were hypertension (X2= 9.36; p=0.01), infections during pregnancy (X2=14.80; p=0.01) and alcohol consumption during pregnancy (X2=97.33; p=0.01). There was a prevalence of 3.9% of HSPM in 14 children, with statistical difference regarding gender (X2 = 4.57; p <0.05), with boys presenting a higher frequency. In G1 hypomineralization was of the type with demarcated opacity, with more prevalent characteristics the yellowish spot, with moderate post-eruptive fracture and acceptable atypical restorations. All lesions were located in the labial region with 1/3 of extension. Conclusion: The prevalence of HSPM in children between 2 and 6 years old was 3.9%, with a predominance in males, with tooth 65 being the most affected. There was an association between HSPM and infection in the first year of life, as well as the use of antibiotics and sensitivity in the teeth affected by the lesion. There was an association between HSPM and hypertension, infection and mothers' alcohol use during pregnancy

Oral squamous cell carcinoma (OSCC) is one of the most well-known malignancies that affect the human population worldwide. The early diagnosis and early intervention of OSCC help improve the survival rate of the patients. The tumour free surgical margins are a positive prognostic factor for recurrence-free survival. The molecular markers can be used to detect the tumour free surgical margins. Aim: The aim of the study is to evaluate the expression of p53 & Cyclin D1 marker in resected surgical apparently clear margins and to correlate the p53 & Cyclin D1 expression with clinicopathological characteristics and patient outcome. Methods: The study population included retrospective cases of OSCC with apparently clear margins (2017-18) n=10 and Clinicopathological variables relevant to survival analysis were recorded. Finally, two margins were selected from each case, a total of 20 margins were included in this study. Paraffin-embedded wax blocks retrieved and tissue sections were made. Expression of cyclin D1 and p 53 was assessed by the immunohistochemical staining procedure Results: Positive expressions Cyclin D1 in 40% of mild dysplasia margins and 60% in clearance adequate margins were present. p53 expression was seen in 16% of mild dysplasia margins and 84% in clearance adequate margins. The expression of p53 and Cyclin D1 molecular markers are noted in the basal & parabasal layer of epithelium. Conclusion: Molecular markers could play a more reliable method for the assessment of dysplasia at the margins

Aim: To evaluate orthodontists' knowledge and clinical practices regarding the treatment of patients with HIV/AIDS. Methods: Cross-sectional study performed with 655 Brazilian orthodontists based on a previously calculated sample size. Self-administered questionnaires were sent to orthodontists to collect information on knowledge and clinical conduct regarding the care of patients with HIV/AIDS. The study evaluated the awareness of possible risk factors for contamination, oral manifestations of HIV, need for more information on the care of HIV-positive patients, whether orthodontic treatment is indicated in HIV-positive patients, and whether they had knowingly performed orthodontic treatment in HIV-positive patients. Simple regression models were adjusted, and crude Odds Ratios estimated the associations with 95% confidence intervals. The variables with P < 0.20 in the crude analysis were tested in multiple logistic regression models, and those with P ≤ 0.05 were maintained in the final model. Magnitudes were estimated by adjusted Odds Ratios values, with 95% confidence intervals. Results: Orthodontists who were aware of the oral manifestations of HIV/AIDS, those having work experience of more than 20 years, and those who believed that orthodontic treatment could be indicated for these patients were 3.30 (1.79-6.10), 2.74 (1.36-5.52) and 1.92 (1.13-3.24) times more likely to perform orthodontic treatment in HIV-positive patients, respectively. Most orthodontists (92.9%) reported they needed to obtain more information about orthodontic care in patients with HIV/AIDS. Conclusion: Although orthodontists reported feeling able and qualified to provide dental care to patients with HIV/AIDS, gaps in their knowledge need to be addressed with further training

Aim: The mandible is regarded as a frequently fractured bone in patients who present with maxillofacial trauma accounting for almost 15.5% to 59% of all facial fractures. Managing condylar trauma has remained to be a point of contention amongst experts, regardless of the advances in surgical modalities and methodologies, and the treatment plan is often determined by the preference and the experience of the surgeon. There exist various approaches in the literature, each with its own specific benefits and drawbacks. With this study, we aimed to evaluate the prevalence of post-operative complications in patients who experienced ORIF by means of the retromandibular approach, by comparing the outcomes of one group having undergone transparotid surgery, with another that underwent retroparotid surgery. Methods: An experimental trial was undertaken. Convenience sampling was done from among the cases of condylar neck and base fracture visiting the department of OMFS, Dow University of Health Sciences from January 2017 to December 2019. An overall 26 patients were divided into 2 groups of 13 members each; one was managed using Open Reduction Internal Fixation (ORIF) by means of a retromandibular transparotid approach while the other group was treated with ORIF by means of a retromandibular retroparotid approach. A 6 month follow-up was done to assess range of active motion, occlusion, and complications such as deviation/deflection, neural injury, infections, sialocele, salivary fistulae and Frey's syndrome in both groups. Results: There was no statistically significant difference between the two groups in terms of inter-incisal opening, right and left lateral movements, or protrusion. One patient in the retroparotid group had deviation on mouth opening (7.69%), while one in the transparotid group reported with infection (7.69%), and 2 developed post operative seromas (15.38%). None had persisting facial nerve palsy at 6 months. Conclusion: We find no significant disparity between the 2 approaches at a follow-up of 6 months; therefore, the primary determining factor for selection of either technique is surgeon preference and appropriate case selection

As fraturas faciais em crianças são raras, já que os ossos faciais pediátricos têm maior elasticidade, menos pneumatização, tecido adiposo circundante mais espesso e mais estabilização da mandíbula e maxila pelos dentes não irrompidos. Em geral, lesões nos tecidos moles são mais comuns em crianças do que fraturas esqueléticas. Entre as fraturas faciais pediátricas, as fraturas da mandíbula são as mais comuns, sendo o côndilo a área mais acometida em pacientes pediátricos. O côndilo é considerado o principal centro de crescimento da mandíbula em crianças, assim é de suma importância a definição do tratamento adequado, pautado em diversos critérios de avaliação, com o intuito de erradicar possíveis complicações advindas da fratura condilar. Assim o objetivo deste estudo é relatar um caso de fratura de côndilo unilateral em uma criança, na qual realizou-se abordagem cirúrgica com fixação interna, afim de elucidar e discutir as possíveis condutas terapêuticas acerca de tratamentos a serem aplicados, visto que esses ainda são bastante controversos na literatura e os resultados das diversas condutas são os mais diversos, apresentando variados aspectos que interferem na evolução dos pacientes(AU)

Facial fractures in children are rare, since pediatric facial bones have greater elasticity, less pneumatization,thicker surrounding adipose tissue and more stabilization of the jaw and jaw by unerupted teeth.In general, soft tissue injuries are more common in children than skeletal fractures.Among pediatric facial fractures, mandible fractures are the most common, with condyl being the most affected area in pediatric patients.The condyl is considered the main center of mandible growth in children, so it is of Paramount importance to define the appropriate treatment, based on several evaluationcriteria, in order to eradicate possible complications resulting from the condilar fracture.Thus, the aim of this study is to report a case of unilateral condyl fracture in a child, in which a surgical approach with internal fixation was performedin order to elucidate and discuss the possible therapeutic approaches about treatments to be applied, since these are still quite controversial in the literature and the results of the various behaviors are the most diverse,presenting several aspects that interfere in the evolution of patients(AU)

Resumen La trombosis venosa cerebral (TVC) es una presentación clínica poco común del tromboembolismo venoso caracterizada por cefalea, crisis convulsivas, déficits neurológicos focales y papiledema. El diagnóstico es confirmado con Tomografía axial computarizada (TAC) de cráneo y Resonancia magnética nuclear (RMN) cerebral. La TVC tiene una relación importante con el virus de inmunodeficiencia humana (VIH), ya que los pacientes VIH positivos cursan con hiperviscosidad san guínea, alteraciones de factores anticoagulantes endógenos y riesgo de sobreinfección, entre otros; que predisponen a estados protrombóticos y lesión vascular como lo es la TVC. El tratamiento de la TVC es terapia anticoagulante, por lo general se utiliza heparina no fraccionada o heparina de bajo peso molecular para la fase aguda y anticoagulantes orales como la warfarina para el mantenimiento posterior. Reportamos el primer caso documentado de TVC en un paciente VIH positivo en Colombia.

Abstract Cerebral venous thrombosis (CVT) is a rare clinical presentation of venous thromboembolism characterized by headache, seizures, neurological deficits and papi lledema. The diagnosis is confirmed using computed tomography scan (CT scan) and magnetic resonance imaging (MRI) of the brain. CVT has an important relationship with the human immunodeficiency virus (HIV) given that HIV-positive patients may present with blood hyperviscosity, irregular levels of endogenous anticoagulation factors and risk of sepsis among others, that predispose to prothrombotic states and vascular injury such as CVT. The treatment of CVT is anticoagulant therapy, generally unfractionated heparin or low molecular weight heparin for the early phase and oral anticoagulants such as warfarin for the late phase. This case reports the first documented case of CVT in an HIV positive patient in Colombia.

As dificuldades que apontaram em lidar com a morte se referem à falta de suporte psicológico, escassez de conhecimento sobre morte, cuidados paliativos e comunicação de más notícias. Conclusão: os profissionais construíram diferentes significados à morte de seus pacientes, tais como um processo natural da vida, vontade de um ser superior, passagem para uma nova existência e término do sofrimento dessas pessoas.

Objective: to understand the construction of meanings of death by healthcare professionals caring for people with cancer. Method: this qualitative study was carried out in an online environment through semi-structured interviews of 34 health professionals, which were interpreted using thematic analysis. Results: two analytical categories emerged from the data, indicating that the meanings attributed to death by the participants were: a process inherent in the human life cycle, a transition to the next life, and an end to the suffering of both patient and health professionals. The difficulties they pointed to in dealing with death related to lack of psychological support, lack of knowledge about death, palliative care, and communicating bad news. Conclusion: the professionals constructed different meanings to their patients' deaths: a natural process of life, the will of a higher being, a transition to a new existence, and an end to these people's suffering.

BACKGROUND: Laennec's capsule has been found for about 200 years. However, laparoscopic anatomical right and left hemihepatectomy (LARH and LALH) using Laennec's approach are rarely reported. METHODS: We retrospectively analyzed the technical details and the surgical outcomes of 15 patients who underwent LAH via Laennec's approach between May 2017 and July 2020. The operation time, intraoperative blood loss, postoperative complications, and hospital stay were recorded and analyzed. RESULTS: Four of 15 patients were diagnosed with hepatic hemangioma, 2 had hepatolithiasis, and 9 patients had primary liver cancer. During the surgery, Laennec's approach was used for LAH without conversion to open surgery. Four patients were treated with LARH, and 11 patients were cured with LALH. The mean age of the patients was 62.1 ± 6.5 years, and four were male. The mean operative time, blood loss, and length of the postoperative hospital stay were 193 ± 49 min, 247 ± 120 mL, and 8.7 ± 2.0 days, respectively. There was no incidence of postoperative bile leakage and bleeding. No mortality occurred. We also demonstrated that Laennec's capsule does exist around the peripheral hepatic veins with histological confirmation. CONCLUSIONS: Laennec's approach is safe and feasible for LAH. Precise isolation of Laennec's approach based on Laennec's capsule helps to standardize the surgical techniques for laparoscopic anatomical hepatectomy.

OBJECTIVE: To determine if virtual care with remote automated monitoring (RAM) technology versus standard care increases days alive at home among adults discharged after non-elective surgery during the covid-19 pandemic. DESIGN: Multicentre randomised controlled trial. SETTING: 8 acute care hospitals in Canada. PARTICIPANTS: 905 adults (≥40 years) who resided in areas with mobile phone coverage and were to be discharged from hospital after non-elective surgery were randomised either to virtual care and RAM (n=451) or to standard care (n=454). 903 participants (99.8%) completed the 31 day follow-up. INTERVENTION: Participants in the experimental group received a tablet computer and RAM technology that measured blood pressure, heart rate, respiratory rate, oxygen saturation, temperature, and body weight. For 30 days the participants took daily biophysical measurements and photographs of their wound and interacted with nurses virtually. Participants in the standard care group received post-hospital discharge management according to the centre's usual care. Patients, healthcare providers, and data collectors were aware of patients' group allocations. Outcome adjudicators were blinded to group allocation. MAIN OUTCOME MEASURES: The primary outcome was days alive at home during 31 days of follow-up. The 12 secondary outcomes included acute hospital care, detection and correction of drug errors, and pain at 7, 15, and 30 days after randomisation. RESULTS: All 905 participants (mean age 63.1 years) were analysed in the groups to which they were randomised. Days alive at home during 31 days of follow-up were 29.7 in the virtual care group and 29.5 in the standard care group: relative risk 1.01 (95% confidence interval 0.99 to 1.02); absolute difference 0.2% (95% confidence interval -0.5% to 0.9%). 99 participants (22.0%) in the virtual care group and 124 (27.3%) in the standard care group required acute hospital care: relative risk 0.80 (0.64 to 1.01); absolute difference 5.3% (-0.3% to 10.9%). More participants in the virtual care group than standard care group had a drug error detected (134 (29.7%) v 25 (5.5%); absolute difference 24.2%, 19.5% to 28.9%) and a drug error corrected (absolute difference 24.4%, 19.9% to 28.9%). Fewer participants in the virtual care group than standard care group reported pain at 7, 15, and 30 days after randomisation: absolute differences 13.9% (7.4% to 20.4%), 11.9% (5.1% to 18.7%), and 9.6% (2.9% to 16.3%), respectively. Beneficial effects proved substantially larger in centres with a higher rate of care escalation. CONCLUSION: Virtual care with RAM shows promise in improving outcomes important to patients and to optimal health system function. TRIAL REGISTRATION: NCT04344665.

BACKGROUND: Ixekizumab is monoclonal antibody targeted against interleukin-17 (IL-17) and has been approved for use in chronic plaque psoriasis. Despite its efficacy in treating psoriasis, concerns have been raised regarding Ixekizumab's potential to induce and exacerbate inflammatory bowel disease (IBD). CASE PRESENTATION: Here we report the new onset of severe drug-associated colitis with surgical complications in a 45-year-old male patient who was receiving Ixekizumab therapy for chronic plaque psoriasis. Review of the patient's colonic pathology demonstrated acute inflammatory changes with features of Crohn's disease. The patient remained disease-free 9-months following his hospitalization and cessation of Ixekizumab. CONCLUSIONS: This case raises suspicion for an association between Ixekizumab and IBD and calls on clinicians to have heightened awareness of potential risks before prescribing anti-IL-17 agents.

BACKGROUND: Synchronous colorectal cancer (SCRC) is featured by the presence of multiple primary tumor lesions in a single patient at initial diagnosis. It is less common with the prevalence of approximately 3.5% among colorectal cancer (CRC). Some studies of SCRC have been performed in patients with two tumor lesions. However, SCRC cases with three or more tumor lesions were rare and remained to be investigated. CASE PRESENTATION: In this case report, we presented a 56-year-old male SCRC case with quadruple tumor lesions which is rarely seen in clinical practice. After laparoscopic radical resection of sigmoid carcinoma and partial rectum resection, the four tumor samples were subjected to pathological evaluation and next-generation sequencing (NGS) based genetic profiling. The four tumor lesions included two adenocarcinomas with moderate differentiation at sigmoid colon and rectum respectively, a grade 1 neuroendocrine tumor (NET) at rectum and a high-grade intraepithelial neoplasia at ascending colon. Each tumor exhibited distinct histology types and mutation profiles. After surgical resection, the patient remained disease-free after four cycles of chemotherapy with oxaliplatin and capecitabine (XELOX). CONCLUSIONS: The tumor lesions in this case showed different pathological and genetic features which indicats the heterogeneity of SCRC. The genomic profilling might provide novel insights to understand SCRC at molecular level.

OBJECTIVE: The objective of this study was to employ ensemble clustering and tree-based risk model approaches to identify interactions between clinicogenomic features for colorectal cancer using the 100,000 Genomes Project. RESULTS: Among the 2211 patients with colorectal cancer (mean age of diagnosis: 67.7; 59.7% male), 16.3%, 36.3%, 39.0% and 8.4% had stage 1, 2, 3 and 4 cancers, respectively. Almost every patient had surgery (99.7%), 47.4% had chemotherapy, 7.6% had radiotherapy and 1.4% had immunotherapy. On average, tumour mutational burden (TMB) was 18 mutations/Mb and 34.4%, 31.3% and 25.7% of patients had structural or copy number mutations in KRAS, BRAF and NRAS, respectively. In the fully adjusted Cox model, patients with advanced cancer [stage 3 hazard ratio (HR) = 3.2; p < 0.001; stage 4 HR = 10.2; p < 0.001] and those who had immunotherapy (HR = 1.8; p < 0.04) or radiotherapy (HR = 1.5; p < 0.02) treatment had a higher risk of dying. The ensemble clustering approach generated four distinct clusters where patients in cluster 2 had the best survival outcomes (1-year: 98.7%; 2-year: 96.7%; 3-year: 93.0%) while patients in cluster 3 (1-year: 87.9; 2-year: 70.0%; 3-year: 53.1%) had the worst outcomes. Kaplan-Meier analysis and log rank test revealed that the clusters were separated into distinct prognostic groups (p < 0.0001). Survival tree or recursive partitioning analyses were performed to further explore risk groups within each cluster. Among patients in cluster 2, for example, interactions between cancer stage, grade, radiotherapy, TMB, BRAF mutation status were identified. Patients with stage 4 cancer and TMB ≥ 1.6 mutations/Mb had 4 times higher risk of dying relative to the baseline hazard in that cluster.
