RESUMO

INTRODUCTION: Vitiligo was historically regarded as a cosmetic disorder; however, it is an autoimmune disease. As a visible condition, it affects patient well-being. We assessed the impact of disease severity, lesion location, and body surface area (BSA) affected on patient health-related quality of life (HRQoL). METHODS: Retrospective data were from the Adelphi Real World Vitiligo Disease Specific Programme: a cross-sectional survey of physicians and their patients with vitiligo (10/2021-07/2022). Patient-reported outcomes were assessed by the Vitiligo-Specific Quality of Life Instrument (VitiQoL), Hospital Anxiety and Depression Scale (HADS), and EQ-5D-5L. The Work Productivity and Impairment Questionnaire (WPAI) questionnaire was used to assess disease-related impairment of daily activities. Data were stratified by physician-reported disease severity, presence/absence of vitiligo on the face, and BSA percentage affected. RESULTS: In total, 1388 patients were included. Mean (SD) VitiQoL, HADS depression, and anxiety scores were higher for those with severe disease [40.5 (26.1), 5.2 (4.4), and 6.8 (4.7)] than those with mild [24.8 (18.8), 3.6 (3.8), 4.2 (3.8)] or moderate [27.1 (22.6), 3.8 (4.5), 4.3 (4.4)] disease. Patients with face affected reported higher VitiQoL [30.0 (22.3) versus 23.2 (19.3)], and HADS scores [depression, 4.3 (4.3) versus 3.2 (3.9); anxiety, 5.0 (4.3) versus 3.8 (3.9)] than those without. Patients with ≥ 5% BSA affected had higher VitiQoL, depression and anxiety scores [27.9 (21.8), 4.0 (4.4), and 4.5 (4.2)] than those with 0-5% [24.6 (19.7), 3.4 (3.7), and 4.3 (4.1)]. Patients with severe vitiligo, facial lesions, or ≥ 5% BSA reported higher activity impairment. Mean EQ-5D-5L-utility score was approximately 0.9 regardless of disease severity or total BSA affected. CONCLUSIONS: These data demonstrate the impact disease severity can have on HRQoL and daily activities for patients with vitiligo. Lesions that are more severe, on the face, or covering a greater BSA are more often associated with poorer outcomes and activity impairment. These data also highlight the potential insensitivity of commonly used HRQoL measures and a need for more sensitive disease-specific measures.


Vitiligo is a disorder that causes patches of skin to lose pigment. In this study, we examined medical records of patients who have non-segmental vitiligo (the most common type of vitiligo) to better understand how the following factors affect the quality of life of patients with non-segmental vitiligo: (a) disease severity, (b) whether the face was affected, and (c) how much of the body was affected. Using a variety of measures, we found that patients with non-segmental vitiligo had lower quality of life, more symptoms of anxiety and depression, and higher activity impairment than those who did not. Our research highlights the differences in the measures used to assess the quality of life of patients, as well as the need for new therapies for non-segmental vitiligo.

RESUMO

Resistance to cancer immunotherapy is mainly attributed to poor tumor immunogenicity as well as the immunosuppressive tumor microenvironment (TME) leading to failure of immune response. Numerous therapeutic strategies including chemotherapy, radiotherapy, photodynamic, photothermal, magnetic, chemodynamic, sonodynamic and oncolytic therapy, have been developed to induce immunogenic cell death (ICD) of cancer cells and thereby elicit immunogenicity and boost the antitumor immune response. However, many challenges hamper the clinical application of ICD inducers resulting in modest immunogenic response. Here, we outline the current state of using nanomedicines for boosting ICD of cancer cells. Moreover, synergistic approaches used in combination with ICD inducing nanomedicines for remodeling the TME via targeting immune checkpoints, phagocytosis, macrophage polarization, tumor hypoxia, autophagy and stromal modulation to enhance immunogenicity of dying cancer cells were analyzed. We further highlight the emerging trends of using nanomaterials for triggering amplified ICD-mediated antitumor immune responses. Endoplasmic reticulum localized ICD, focused ultrasound hyperthermia, cell membrane camouflaged nanomedicines, amplified reactive oxygen species (ROS) generation, metallo-immunotherapy, ion modulators and engineered bacteria are among the most innovative approaches. Various challenges, merits and demerits of ICD inducer nanomedicines were also discussed with shedding light on the future role of this technology in improving the outcomes of cancer immunotherapy.

RESUMO

Patients receiving interleukin (IL)-inhibiting biologics for moderate-to-severe psoriasis (PsO) may be treated with escalated doses to optimize outcomes. This study evaluated escalation prevalence in a Japanese claims analysis of patients with PsO diagnosis preceding IL-inhibiting biologic treatment and ≥1 post-induction maintenance claim (index date) with sufficient data availability from January 2014 to May 2022. Patients with non-persistence were excluded. Expected daily dose (EDD) was calculated as the recommended maintenance dose divided by the treatment interval. Dose escalation was defined as ≥2 claims showing a ≥20% increase in the observed average daily dose (ADD) over the EDD (with sensitivities requiring ≥1 claim and ≥30%). Significant differences were tested using multivariable regressions. The study included 982 unique patients treated with brodalumab (BRO; n = 104), guselkumab (GUS; n = 207), ixekizumab (IXE; n = 159), risankizumab (RIS; n = 135), secukinumab (SEC; n = 215) and ustekinumab (UST; n = 196). Within 12 months, dose escalation was observed for all IL-inhibiting biologics other than GUS and RIS: 44.4% for UST, 37.2% for IXE, 3.4% for SEC and 1.4% for BRO. In multivariable-adjusted analyses, odds of dose escalation were significantly lower for all products relative to UST. In sensitivities, escalation was observed for all products except RIS.

RESUMO

In Egypt, tick-borne diseases pose a significant threat to human and animal health, and the threat to dromedaries (Camelus dromedarius), the country's dominant camelid species, is of particular concern. These animals are frequently infested with ticks, and may thus develop tick-borne diseases or become reservoirs of tick-borne pathogens. However, there is a paucity of data on tick infestation in Egyptian camels, especially in the south of the country. Accordingly, we aimed to determine the prevalence of tick infestation in southern Egyptian camel populations (in Luxor and Aswan governorates), and identify the hemoprotozoan parasites carried by camel-infesting ticks. Camels were checked for ticks during veterinary examination at quarantine and household checks, and ticks were collected from infested camels for species identification using morphological examination and PCR analyses. Tick and hemoprotozoan species were identified using Basic Local Alignment Search Tool analysis with subsequent confirmation in phylogenetic analyses. All camel-infesting ticks belonged to the species Hyalomma dromedarii, and were clustered with ticks of this species previously found in Egypt in a phylogenetic tree based on the 16S rRNA gene. Molecular analysis targeting the 18S rRNA gene revealed the presence of hitherto undetected hemoprotozoan parasites, Colpodella spp., in 30/297 (10.1 %) camel-infesting ticks. In phylogenetic analysis, these Colpodella spp. were highly homologous (94-98.6 %) with Colpodella spp. previously deposited in GenBank with accession numbers OQ540590Q, MH208621, and GQ411073, which relate to Colpodella spp. previously detected from Haemaphysalis longicornis, Rhipicephalus haemaphysaloides, and humans in China. PCR analyses with spherical body protein-4 (SBP-4) gene-specific primers revealed Babesia bovis in 16/297 (5 %) of camel-infesting ticks, however, Babesia bigemina and Theileria annulata were not detected. Here, we report the first detection of Colpodella spp. in H. dromedarii in Egypt. Further epidemiological studies are needed to assess the risk to camels and humans, and the transmission dynamics. Based on the high tick infestation rates in Egyptian camels and the identification of previously unreported protozoan hemoparasites in ticks, we consider that the dromedary should be subject to surveillance as a sentinel species for tick-borne diseases in Egypt. Our findings underline the need for surveillance and collecting data on lesser known pathogens circulating in camel-infesting ticks, as part of a public health strategy for dealing with tick-borne diseases in Egypt.

RESUMO

BACKGROUND: Chronic liver disease is a common and important clinical problem.Hepatorenal syndrome (HRS) is a life threatening complication. Serum creatinine (Cr) remains the only conventional indicator of renal function. However, the interpretation of serum Cr level can be confounded by malnutrition and reduced muscle mass often observed in patients with severe liver disease. Here, we present a cross-sectional study to explore the sensitivity and specificity of other markers as urinary KIM-1 and NGAL for cases of HRS. METHODS: Cross-sectional study was conducted on 88 patients who were admitted to Alexandria main university hospital. Enrolled patients were divided in two groups; group 1: patients with advanced liver cirrhosis (child B and C) who have normal kidney functions while group 2: patients who developed HRS. Stata© version 14.2 software package was used for analysis. RESULTS: Group 1 included 18 males and 26 females compared to 25 males and 19 females in group 2 (p = 0.135). Only the urinary KIM-1 showed a statistically significant difference between both groups in the multivariate logistic regression analysis adjusted for gender, serum bilirubin, serum albumin, INR, serum K, AST and ALT levels. CONCLUSION: In conclusion, our study aligns with prior research, as seen in the consistent findings regarding Urinary NGAL elevation in cirrhotic patients with AKI. Urinary KIM-1, independent of Urinary NGAL, may have a role in precisely distinguishing between advanced liver cirrhosis and HRS and merits further exploration.

RESUMO

INTRODUCTION: Real-world data on the efficacy of risankizumab (RZB) in clinical moderate-to-severe plaque psoriasis (PsO) are limited. The RAPID study assessed real-world clinical and patient-reported outcomes in RZB-treated PsO patients using data collected from dermatologists in Canada, the Czech Republic, Germany, Japan, and Poland. METHODS: This ongoing, retrospective chart review collected data from medical records of RZB-treated adults with moderate-to-severe PsO (09/2022-06/2023). Eligible patients received RZB, had ≥ 12 months of medical records after RZB initiation (index date), and had Psoriasis Area and Severity Index (PASI), Investigator Global Assessment (IGA), or static Physician's Global Assessment (sPGA) scores ≥ 3 months before and up to 18 months after the index date. The proportion of patients achieving a clear/almost clear PsO (IGA/sPGA = 0/1), PASI ≤ 1, Dermatology Life Quality Index (DLQI) = 0/1, and a 90%/100% improvement from baseline in PASI as well as the mean changes in PASI, DLQI, itch, and skin pain scores at 12 and 18 months were reported for patients with non-missing assessments at baseline and 12 months. RESULTS: Most patients (66.4%) were male, 74.0% were biologic naïve, and 73.0% had scalp PsO. Mean baseline IGA/sPGA was 3.7 ± 0.5, with a mean PASI of 23.3 ± 11.8. After 12 months, 86.1% of patients reported IGA/sPGA ≤ 1, and 75.7% achieved PASI90; these further increased to 91.1% and 80.5% at 18 months. DLQI, itch, and skin pain scores improved over time. CONCLUSIONS: These data demonstrated the durable, real-world effectiveness of RZB in patients with moderate-to-severe PsO through continued improvement in disease and symptom severity over 18 months, with most of the patients reporting clear/almost clear skin.

RESUMO

INTRODUCTION: Plaque psoriasis is a common, often debilitating, chronic autoimmune inflammatory skin disease. Moderate-to-severe forms of psoriasis can be treated with biologics such as anti-interleukin and anti-tumor necrosis factor antibodies. We aimed to investigate treatment discontinuation among patients with psoriasis who initiated biologic treatment. METHODS: We conducted a retrospective, non-interventional cohort study based on anonymized claims data from the German statutory health insurance which covered the years from 2016 to 2021. We included adult patients with psoriasis who initiated biologic treatment in drug-specific cohorts. Over a 365-day follow-up period, we assessed the frequencies and the time until treatment discontinuation for different biologics. Differences in discontinuation rates were compared using a multivariate Cox proportional hazards model. RESULTS: A total of 2565 patients with psoriasis who initiated treatment with secukinumab (n = 612), adalimumab (n = 454), guselkumab (n = 354), ixekizumab (n = 259), ustekinumab (n = 241), tildrakizumab (n = 205), brodalumab (n = 166), risankizumab (n = 145), etanercept (n = 91), certolizumab (n = 29), and infliximab (n = 9) were included. A total of 1290 patients (50.29%) discontinued treatment during the follow-up period, ranging from 30.34% (risankizumab) to 69.23% (etanercept). Median time until discontinuation of treatment ranged from 102 days (etanercept) to 208 days (risankizumab). Once the biologic treatment was discontinued, 45.05% of patients restarted the treatment with the same agent, 23.10% of patients switched to another biologic, and 31.86% received no further biologic agent. Compared to patients treated with risankizumab, the treatment discontinuation rate was significantly higher (p < 0.05) in patients treated with the other biologics except ustekinumab (p = 0.12). CONCLUSIONS: Further research should explore reasons leading to treatment discontinuation in order to support treatment choices for patients with moderate-to-severe psoriasis.

RESUMO

Piroplasmosis, a tick-borne disease affecting livestock, including camels, is caused by intracellular apicomplexan parasites belonging to the order Piroplasmida. Despite its importance, there's limited research on piroplasmosis among Egyptian camels. This study aimed to fill this gap by investigating tick-borne piroplasmids in camels from Cairo and Giza Governorates. Out of 181 blood samples collected between October 2021 and March 2022 from apparently healthy one-humped camels (Camelus dromedarius), PCR assays revealed a 41.4 % infection rate with various piroplasmids. Detected species included B. bovis (17.7 %), B. bigemina (12.2 %), B. caballi (8.3 %), B. naoakii (11.6 %), B. microti (1.7 %), T. equi (4.4 %), and Theileria spp. (28.7 %). Phylogenetic analysis revealed the first detection of T. equi genotype E in Egypt and identified a novel B. caballi genotype. Additionally, B. microti isolates were identified as the US-type. These findings shed lights on piroplasmosis among Egyptian camels, and provide valuable information for devising effective control strategies, especially B. microti, a pathogen with potential human health risks.

RESUMO

This paper presents an analysis and prediction of the shear strength of wide-shallow reinforced concrete beams, utilizing Finite Element Analysis (FEA) and machine learning techniques. The methodology involves validating a detailed Finite Element Model (FEM) against experimental results, conducting a parametric study, and developing three Machine Learning prediction equations. The FEM captures concrete and steel behaviors, including cracking and crushing for concrete and linear isotropic properties for steel reinforcement. Loading and boundary conditions are defined for accuracy and validated against 13 experimental specimens, exhibiting a maximum 8% and 12% difference in loads and deflections, respectively. A parametric study generates a dataset of 77 wide beam configurations, exploring variations in beam widths, concrete strengths, compression rebars, and shear reinforcement. This dataset is used to develop machine learning models, including "Genetic Programming (GP)", "Evolutionary Polynomial Regression (EPR)", and "Artificial Neural Network (ANN)". Comparative analysis reveals GP and EPR models with over 95% correlation, while the ANN model outperforms with 99% accuracy. Sensitivity analysis underscores the significant influence of concrete strength and beam aspect ratio on shear strength. In conclusion, the study demonstrates the potential of FEA and machine learning models to predict shear strength in wide-shallow reinforced concrete beams, providing valuable insights for architectural design and engineering practices and emphasizing the role of concrete strength and beam geometry in shear behavior.

RESUMO

INTRODUCTION: The presence (vs absence) of enthesitis/dactylitis is associated with greater psoriatic arthritis (PsA) activity and reduced health-related quality of life. Risankizumab, an interleukin 23 antagonist, demonstrated superior treatment efficacy over placebo in patients with PsA, including enthesitis/dactylitis. Herein, we report the efficacy of risankizumab on complete resolution of enthesitis and/or dactylitis and improvements in patient-reported outcomes in patients with PsA. METHODS: This integrated post hoc analysis of data from KEEPsAKE 1 and KEEPsAKE 2 included patients with baseline enthesitis (Leeds Enthesitis Index > 0) and/or dactylitis (Leeds Dactylitis Index > 0). Efficacy outcomes at weeks 24 and 52 included proportion of patients achieving enthesitis and/or dactylitis resolution and minimal clinically important differences (MCID) in pain, Health Assessment Questionnaire-Disability Index, and Functional Assessment of Chronic Illness Therapy-Fatigue. RESULTS: Of 1407 patients, approximately 63%, 28%, and 20% had baseline enthesitis, dactylitis, and both enthesitis/dactylitis, respectively. At week 24, higher response rates were observed for risankizumab vs placebo for resolution of enthesitis, dactylitis, and both enthesitis/dactylitis (differences of 13.9%, 16.9%, and 13.3%, respectively; p < 0.05). By week 52, risankizumab treatment resulted in complete resolution of enthesitis, dactylitis, and both enthesitis and dactylitis in 55.0%, 76.1%, and 52.3% of patients; similar resolution rates occurred among patients who switched from placebo to risankizumab. Among risankizumab-treated patients who achieved resolution of enthesitis and/or dactylitis, MCIDs were also attained in patient-reported pain, disability, and fatigue at week 24 (all p < 0.05; except fatigue in patients with resolution of both enthesitis/dactylitis); responses were sustained through week 52. CONCLUSIONS: Higher proportions of risankizumab-treated (vs placebo-treated) patients achieved enthesitis and/or dactylitis resolution and meaningful improvements in patient-reported outcomes at week 24 and generally sustained responses at week 52. Thus, risankizumab may result in sustained alleviation of PsA-related pathognomonic musculoskeletal lesions of enthesitis/dactylitis. GOV IDENTIFIERS: NCT03675308, and NCT03671148.

RESUMO

Recently, skin cancer is one of the spread and dangerous cancers around the world. Early detection of skin cancer can reduce mortality. Traditional methods for skin cancer detection are painful, time-consuming, expensive, and may cause the disease to spread out. Dermoscopy is used for noninvasive diagnosis of skin cancer. Artificial Intelligence (AI) plays a vital role in diseases' diagnosis especially in biomedical engineering field. The automated detection systems based on AI reduce the complications in the traditional methods and can improve skin cancer's diagnosis rate. In this paper, automated early detection system for skin cancer dermoscopic images using artificial intelligent is presented. Adaptive snake (AS) and region growing (RG) algorithms are used for automated segmentation and compared with each other. The results show that AS is accurate and efficient (accuracy = 96%) more than RG algorithm (accuracy = 90%). Artificial Neural networks (ANN) and support vector machine (SVM) algorithms are used for automated classification compared with each other. The proposed system with ANN algorithm shows high accuracy (94%), precision (96%), specificity (95.83%), sensitivity (recall) (92.30%), and F1-score (0.94). The proposed system is easy to use, time consuming, enables patients to make early detection for skin cancer and has high efficiency.

RESUMO

BACKGROUND: ß-Thalassemia major (BTM) is one of the most common hereditary anemias worldwide. Patients suffer from iron overload that results from repeated blood transfusion This in turn leads to multiple organ damage and endocrinopathies. This study aims to assess the prevalence of growth retardation, hypothyroidism, and diabetes mellitus in children and adolescents with BTM treated at Dubai Thalassemia Centre. METHODS: A total of 105 children and adolescents were included in this retrospective observational study. RESULTS: 39 children and 66 adolescents' data were analyzed. Females composed 51.3% (n = 20) of children and 53.0% (n = 35) of adolescents. Pretransfusion hemoglobin below 9 gm/dl was observed in 10.8% (n = 4) and 10.6% (n = 7) in children and adolescents, respectively. The mean age of menarche was 13.5 years. Among all study participants, 22.6% (n = 14) had normal height velocity whereas 37.1% (n = 23) had reduced height velocity in one year and 40.3% (n = 25) had reduced height velocity in two consecutive years. The proportion of children and adolescents showing reduced height velocity was significantly higher in females compared to the males (90.6% versus 63.3%, respectively, Chi-square = 6.597, p-value = 0.010). Although none of the study participants had diabetes mellitus, 26.1% (n = 12/46) had pre-diabetes. Elevated TSH was observed in 14.7% (n = 5) children and 8.1% (n = 5) adolescents while low FT4 was reported in one child and one adolescent. CONCLUSION: Of all endocrinopathies seen among children and adolescents with BTM, growth delay remains the main concern for this group of patients. Effective treatment is key to further reducing endocrinopathies. Although the sample size is limited, we postulate that the low percentage of endocrinopathies among children with BTM treated at Dubai thalassemia center and the low level of pretransfusion anemia reflect the effective transfusion and chelation at the center.

RESUMO

Tick-borne rickettsial pathogens pose significant threats to public and animal health. In Upper Egypt, limited information exists regarding the prevalence and diversity of such tick-borne pathogens. Therefore, this study aimed to conduct a comprehensive investigation to elucidate the presence and variety of tick-borne rickettsial pathogens in Upper Egyptian camels. Our results revealed a prevalence of 2.96 % for Anaplasma marginale and 0.34 % for Candidatus Anaplasma camelii among Hyalomma ticks. However, Ehrlichia spp. weren't detected in our study. The identification of Ca. A. camelii in H. dromedari ticks was documented for the first time, suggesting a potential mode of transmission in camels. Notably, this study marks the first documentation of Rickettsia aeschlimannii with a prevalence of 6.06 % in the study area. Furthermore, we detected Coxiella burnetii in a prevalence of 8.08 % in Hyalomma ticks, indicating a potential risk of Q fever transmission. Molecular techniques results were confirmed by sequencing and phylogenetic analysis and provided valuable insights into the epidemiology of these pathogens, revealing their diversity. This study is vital in understanding tick-borne rickettsial pathogens' prevalence, distribution, and transmission dynamics in Upper Egypt. In conclusion, our findings emphasize the importance of continued research to enhance our understanding of the epidemiology and impact of these pathogens on both animal and human populations.

RESUMO

INTRODUCTION: Long-term therapeutic options providing durable response and tolerability are needed for psoriatic arthritis (PsA). The ongoing KEEPsAKE 2 trial is evaluating risankizumab treatment in patients with active PsA who previously had inadequate response/intolerance to ≥ 1 conventional synthetic disease-modifying antirheumatic drug (csDMARD-IR) and/or 1-2 biologic DMARDs (bDMARD-IR). Herein, we report results through 100 weeks of treatment. METHODS: KEEPsAKE 2 is a global phase 3 trial. Patients with active PsA were randomized 1:1 to double-blind subcutaneous risankizumab 150 mg or placebo (weeks 0, 4, and 16). At week 24, all patients received open-label risankizumab every 12 weeks until end of study. Efficacy endpoints included achieving ≥ 20% improvement in PsA symptoms using American College of Rheumatology criteria (ACR20), attaining minimal disease activity (MDA; meeting ≥ 5/7 criteria of low disease activity and extent), and improving in other measures. RESULTS: At the cutoff date, 345/443 (77.9%) patients were ongoing in the study. ACR20 was achieved in 57.1% and 52.5% of the continuous risankizumab and placebo/risankizumab cohorts, respectively, at week 100 and in 60.0% and 55.8%, respectively, at week 52. In week 52 responders, maintenance of ACR20 at week 100 was achieved in 74.8% (continuous risankizumab) and 78.7% (placebo/risankizumab) of patients. In the continuous risankizumab and placebo/risankizumab cohorts, respectively, MDA was achieved by 33.0% and 33.3% of patients at week 100 and by 27.2% and 33.8% at week 52. Among MDA responders at week 52, maintenance of MDA response was achieved by 83.6% and 73.0% of the continuous risankizumab and placebo/risankizumab cohorts, respectively. Risankizumab was well tolerated through week 100. CONCLUSIONS: Risankizumab demonstrated durable efficacy and tolerability through 100 weeks; most patients who achieved ACR20 and MDA responses at week 52 maintained this achievement through week 100. There were no new safety signals in patients who had csDMARD-IR and bDMARD-IR. TRIAL REGISTRATION: ClinicalTrials.gov NCT03671148.


Risankizumab, a biologic disease-modifying antirheumatic drug, helps control the body's immune system to reduce symptoms of psoriatic arthritis (a disease that inflames the joints of people who have the skin condition psoriasis). The ongoing KEEPsAKE 2 study is evaluating how well risankizumab works and how safe it is for treating adult patients with active psoriatic arthritis who previously experienced inadequate response to one or more specific types of disease-modifying anti-arthritis drugs. Patients were randomly assigned to receive either risankizumab or an inactive drug; after 24 weeks, all patients received risankizumab. At study week 100, 57% of patients who were assigned to receive continuous risankizumab since the start of the study experienced a 20% or more improvement in a measure of psoriatic arthritis symptoms using criteria established by the American College of Rheumatology (ACR20); a similar proportion of patients achieved a 20% improvement at both weeks 24 and 52. Similarly, 56% and 53% of patients who switched from inactive drug to risankizumab achieved ACR20 at weeks 52 and 100 (more than before switching to risankizumab at week 24). Minimal disease activity (MDA) was evaluated by assessing joint and skin symptoms, affected body surface area, pain, and physical function. At week 100, 33% of patients achieved MDA (both groups), which was similar to week 52. Most patients who achieved ACR20 or MDA at week 52 maintained responses at week 100. Improvements with risankizumab were seen in several other measures of treatment outcomes through week 100. Risankizumab was generally safe through 100 weeks.

RESUMO

INTRODUCTION: Patients with psoriatic arthritis (PsA) require treatment providing durable long-term efficacy in different disease domains as well as safety. We present 100-week efficacy and safety results of risankizumab in patients with active PsA and previous inadequate response/intolerance to ≥ 1 conventional synthetic disease-modifying antirheumatic drug (csDMARD-IR). METHODS: KEEPsAKE 1 (NCT03675308) is a global phase 3 study, including a 24-week, double-blind, placebo-controlled and ongoing open-label extension periods. Patients were randomized 1:1 to receive risankizumab 150 mg or placebo at baseline and weeks 4 and 16. After week 24, all patients received open-label risankizumab every 12 weeks thereafter. Patients were evaluated through 100 weeks. Endpoints included achieving ≥ 20% reduction in American College of Rheumatology criteria for symptoms of rheumatoid arthritis (ACR20), minimal disease activity (MDA; defined as ≥ 5/7 criteria of low disease activity and extent), and other measures. RESULTS: Overall, 828/964 (85.9%) patients completed week 100. For patients receiving continuous risankizumab, 57.3%, 70.6%, and 64.3% achieved ACR20 at weeks 24, 52, and 100, respectively. For the placebo/risankizumab cohort, 33.5% achieved ACR20 at week 24 but increased after switching to active treatment at weeks 52 (63.7%) and 100 (62.1%). In ACR20 responders at week 52, 81.2% of both treatment cohorts maintained response at week 100. MDA was achieved by 25.0%, 38.3%, and 38.2% of the continuous risankizumab cohort at weeks 24, 52, and 100. In the placebo/risankizumab cohort, 10.2% achieved MDA at week 24, increasing at weeks 52 (28.0%) and 100 (35.2%). MDA response was maintained at week 100 in week 52 responders in the continuous risankizumab (75.5%) and placebo/risankizumab cohorts (78.2%). Similar trends were observed for other efficacy measures. Risankizumab was generally well tolerated through 100 weeks. CONCLUSIONS: For patients with active PsA who are csDMARD-IR, risankizumab demonstrated durable long-term efficacy and was generally well tolerated, with a consistent long-term safety profile. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT03675308.


Psoriatic arthritis (PsA) often affects individuals with the skin condition psoriasis. A biologic disease-modifying antirheumatic drug can help control inflammation and regulate the immune system to ease symptoms and slow progression of PsA. The ongoing KEEPsAKE 1 study is evaluating the efficacy and safety of risankizumab in patients with active PsA who previously have not had success with ≥ 1 conventional disease-modifying antirheumatic drug. Patients were initially treated with risankizumab 150 mg (continuous risankizumab group) or inactive drug (inactive drug/risankizumab group). After 24 weeks, all received risankizumab for the rest of the study. At week 100, 64% (continuous risankizumab group) and 62% (inactive drug/risankizumab group) of patients had ≥ 20% improvement in PsA symptoms (measured using American College of Rheumatology [ACR20] criteria). Both groups showed similar percentages at week 52 and improvement from week 24. In patients who achieved ACR20 at week 52, 81% maintained their ACR20 response at week 100. Minimal disease activity was defined as a combination of joint and skin symptoms, affected body surface area, pain, and physical functioning. At week 100, 38% of the continuous risankizumab group and 35% of the inactive drug/risankizumab group achieved minimal disease activity. Percentages were similar at week 52 and higher than week 24 in both groups. In patients who achieved minimal disease activity at week 52, 81% maintained response at week 100. All other measures of treatment responses showed similar patterns from the start of risankizumab through week 100. Risankizumab was considered generally safe by the treating physicians.

RESUMO

Stress in poultry production is energy-demanding. Nucleotides and yeast cell-wall products are essential nutrients for broiler performance, gut function, and immune response. Antibiotics, like florfenicol, negatively affect the immune system. A total of 600 one-d-old broiler chickens (Cobb-500) were weighed and randomly allotted into four groups with three replicates each. The control group (G1) received the basal diet, G2 received a diet supplemented with a combination of nucleotides and Saccharomyces cerevisiae derivatives (250 g/Ton), G3 received the basal diet and medicated with florfenicol (25 mg/Kg body weight) in drinking water for 5 days, while G4 received a combination of nucleotides and Saccharomyces cerevisiae-derivatives (250 g/Ton) and medicated with florfenicol in drinking water. Growth performance criteria were recorded weekly. Blood, intestinal contents, small-intestine sections, and litter samples were collected to measure birds' performance, carcass yields, leukocytic counts, antioxidant capacity, antibody titres, phagocytic index, caecal Clostridia, intestinal histomorphometry, and litter hygiene. Nucleotide-supplemented groups (G2 and G4) revealed significant (p ≤ 0.05) improvements in feed conversion, and body weight, but not for carcass yields in comparison to the control. Dietary nucleotides in G2 elevated blood total proteins, leucocytic count, antioxidant capacity, and phagocytic index, while they lowered blood lipids and litter moisture and nitrogen (p ≤ 0.05). Dietary nucleotides in G4 ameliorated the immunosuppressive effect of florfenicol (p ≤ 0.05) indicated in reducing caecal Clostridia, improving duodenal and ileal villi length, and increasing blood albumin and globulin levels, and phagocytosis%. Supplementing diets with nucleotides and yeast products has improved the immune system and provided a healthier gut for broilers.

RESUMO

OBJECTIVE: This study aimed to assess the relative gene expression level of transforming growth factor-ß1 (TGFB1) and haptoglobin (HP) in the peripheral blood of prostate cancer (PCa) patients and evaluate their diagnostic ability. METHODS: A total of 125 participants were enrolled in the present study. Among them, 75 PCa patients, 25 benign prostatic hyperplasia (BPH) patients, and 25 healthy volunteers served as the control group. The relative TGFB1 and HP gene expression level was quantified using real-time polymerase chain reaction. Further, free and total PSA levels were determined using electrochemiluminescence assays. RESULTS: TGFB1 was significantly over-expressed, whereas HP was significantly downregulated in the peripheral blood of PCa patients compared to BPH and control groups (p-value ranges from 0.034 to <0.001). Moreover, the high expression level of TGFB1 was associated with an increased risk of PCa development with OR=1.412 (95%CI: 1.081-1.869, p= 0.012). TGFB1 and HP relative expression levels had lower diagnostic performance to differentiate PCa from normal and BPH individuals compared to PSA, however, the combination of the tested parameters improved the diagnostic efficacy. CONCLUSIONS: TGFB1 and HP relative expression have moderate diagnostic efficacy in discriminating patients with PCa from BPH and healthy subjects. Furthermore, over-expression of TGFB1 may contribute to the pathogenesis of PCa.

RESUMO

Tauopathies such as Alzheimer's disease are characterized by aggregation and increased phosphorylation of the microtubule-associated protein tau. Tau's pathological changes are closely linked to neurodegeneration, making tau a prime candidate for intervention. We developed an approach to monitor pathological changes of aggregation-prone human tau in living neurons. We identified 2-phenyloxazole (PHOX) derivatives as putative polypharmacological small molecules that interact with tau and modulate tau kinases. We found that PHOX15 inhibits tau aggregation, restores tau's physiological microtubule interaction, and reduces tau phosphorylation at disease-relevant sites. Molecular dynamics simulations highlight cryptic channel-like pockets crossing tau protofilaments and suggest that PHOX15 binding reduces the protofilament's ability to adopt a PHF-like conformation by modifying a key glycine triad. Our data demonstrate that live-cell imaging of a tauopathy model enables screening of compounds that modulate tau-microtubule interaction and allows identification of a promising polypharmacological drug candidate that simultaneously inhibits tau aggregation and reduces tau phosphorylation.

RESUMO

Background and Objectives: Methicillin-resistant Staphylococcus aureus (MRSA) is a major concern in Jordanian hospitals in terms of infection control. The purpose of this study was to identify the resistance patterns of Staphylococcus aureus strains isolated from surfaces of critical locations within the Al-Karak Governmental Hospital in 2019. Additionally, the study aimed to conduct whole-genome sequencing on the isolates. Materials and Methods: In February 2019, fourteen S. aureus strains were isolated from surfaces in critical sites in the Al-Karak Governmental Hospital. These isolates underwent antibiogram testing to determine their resistance profile. Genome sequencing using the Illumina MiSeq platform was applied to the extracted DNA from these isolates. The genomic data, including coding sequences, were analyzed to identify lineage, resistance genes, and plasmids. Results: The antibiogram results revealed that 11 of the 14 isolates were resistant to oxacillin, 6 to linezolid, and 1 to rifampicin, while none showed resistance to chloramphenicol. Eleven isolates were identified as MRSA, with a novel spa type (t4407) not previously reported in Jordan. High-quality sequencing data were obtained for only one isolate, i.e., A29, the genome showed 2,789,641 bp with a 32.7% GC content and contained 2650 coding sequences. Genomic analysis indicated the ST6 lineage, mecA gene (SCCmec type IVa(2B)), and a hybrid plasmid (pJOR_blaZ) carrying the blaZ gene for ß-lactam resistance. Genomic data were deposited in NCBI (CP104989). The A29 genome closely resembled an MRSA genome isolated from a Danish hospital in 2011. The SNP analysis revealed identical antimicrobial resistance genes in these two genomes. Conclusions: This study unveils the first genomic sequence of an MRSA isolate from Jordan, marked by distinctive genotypic traits. The findings enhance our understanding of the MRSA types circulating in Jordan and the region and substantiate the phenomenon of intercontinental MRSA transmission.

RESUMO

Dicyandiamide (DCD) reacted with amino acids 1a-f to produce biguanides 2 and 4 and guanidine pyrazolones 3, 5, 6, 7, and 8, according to the reaction. DCD exhibited the following reactions: imidodicarbonimidicdiamide 9, diazocan-2-ylguanidine 10, methyl biguanidylthion 11, N-carbamothioylimidodicarbonimidicdiamide 12, 2-guanidinebenzoimidazole 13a, 2-guanidinylbenzoxazole 13b, and 2-guanidinylbenzothiazol 13c. These reactions were triggered by 6-amino caproic acid, thioacetamide, thiourea, o-aminophenol, o-aminothiophenol, and anthranilic acid, respectively. Compound 2 had the least antimicrobial activity, while compound 13c demonstrated the most antibacterial impact against all bacterial strains. Furthermore, in terms of antiglycation efficacy (AGEs), 12, 11, and 7 were the most effective AGE cross-linking inhibitors. Eight and ten, which showed a considerable inhibition on cross-linking AGEs, come next. Compounds 4 and 6 on the other hand have shown the least suppression of AGE production. The most promising antiglycation scaffolds 8, 11, and 12 in the Human serum albumin (HAS) active site were shown to be able to adopt crucial binding interactions with important amino acids based on the results of in silico molecular docking. The most promising antiglycation compounds 8, 11, and 12 were also shown to have better hydrophilicity, acceptable lipophilicity, gastrointestinal tract absorption (GIT), and blood-brain barrier penetration qualities when their physicochemical properties were examined using the egg-boiled method.
