[PMID: 38360900 PMCID: PMC10869804 DOI: 10.1038/s41598-024-54508-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Accepted: 02/13/2024] [Indexed: 02/17/2024] Open
Abstract
The orf63 gene resides in a region of the lambda bacteriophage genome between the exo and xis genes and is among the earliest genes transcribed during infection. In lambda phage and Shiga toxin (Stx) producing phages found in enterohemorrhagic Escherichia coli (EHEC) associated with food poisoning, Orf63 expression reduces the host survival and hastens the period between infection and lysis thereby giving it pro-lytic qualities. The NMR structure of dimeric Orf63 reveals a fold consisting of two helices and one strand that all make extensive intermolecular contacts. Structure-based data mining failed to identify any Orf63 homolog beyond the family of temperate bacteriophages. A machine learning approach was used to design an amphipathic helical ligand that bound a hydrophobic cleft on Orf63 with micromolar affinity. This approach may open a new path towards designing therapeutics that antagonize the contributions of Stx phages in EHEC outbreaks.

Antimicrob Agents Chemother 2024; 68:e0069523. [PMID: 38084954 PMCID: PMC10777851 DOI: 10.1128/aac.00695-23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Accepted: 11/10/2023] [Indexed: 01/11/2024] Open
Abstract
Carbapenem-resistant Enterobacteriaceae (CREs) are described by the Centers for Disease Control as an urgent threat, and there is a critical need for new therapeutic agents able to treat infections caused by these pathogens. Herein, we describe the microbiological profile, the mechanism f action, and the in vitro safety as well as the pharmacokinetic (PK)/PD profile of SMT-738, a small molecule belonging to a new chemical class. SMT-738 is active against Enterobacterales [including multi-drug-resistant Escherichia coli with 90% of isolates having a minimum inhibitory concentration (MIC90) of 1 µg/mL and Klebsiella pneumoniae 2 µg/mL] and inactive against a broad panel of Gram-negative and Gram-positive pathogens. SMT-738 displays rapid bactericidal activity (2-4 h) and has a low propensity for resistance development (less than ~10-9). Characterization of resistant mutants following exposure to SMT-738 identified mutations within the lipoprotein transport complex (LolCDE), a clinically unexploited and essential bacterial molecular target in Gram-negative bacteria. SMT-738 has a promising in vitro toxicology profile. Furthermore, PK studies demonstrated that when dosed intravenously, SMT-738 maintained exposure levels across infection sites (bloodstream/urinary tract/lung). Proof-of-concept studies across multiple murine in vivo infection models (bloodstream/pneumonia/urinary tract) demonstrated that SMT-738 significantly reduced the bacterial burden compared to baseline and vehicle control. SMT-738 represents a promising novel drug candidate being developed to address clinically challenging serious life-threatening infections caused by highly resistant Enterobacteriaceae including CRE.

Abstract
BACKGROUND Currently, magnetic resonance spectroscopy (MRS) is dependent on the investigative team to manually prescribe, or demarcate, the desired tissue volume-of-interest. The need for a new method to automate precise voxel placements is warranted to improve the utility and interpretability of MRS data. NEW METHOD We propose and validate robust and real-time methods to automate MRS voxel placement using functionally defined coordinates within the prefrontal cortex. Data were collected and analyzed using two independent prospective studies: 1) two independent imaging days with each consisting of a multi-session sandwich design (MRS data only collected on one of the days determined based on scan time) and 2) a longitudinal design. Participants with fibromyalgia syndrome (N = 50) and major depressive disorder (N = 35) underwent neuroimaging. MRS acquisitions were acquired at 3-tesla. Evaluation of the reproducibility of spatial location and tissue segmentation was assessed for: 1) manual, 2) semi-automated, and 3) automated voxel prescription approaches RESULTS: Variability of voxel grey and white matter tissue composition was reduced using automated placement protocols. Spatially, post- to pre-voxel center-of-gravity distance was reduced and voxel overlap increased significantly across datasets using automated compared to manual procedures COMPARISON WITH EXISTING METHODS: Manual prescription, the current standard in the field, can produce inconsistent data across repeated acquisitions. Using automated voxel placement, we found reduced variability and more consistent voxel placement across multiple acquisitions CONCLUSIONS: These results demonstrate the within subject reliability and reproducibility of a method for reducing variability introduced by spatial inconsistencies during MRS acquisitions. The proposed method is a meaningful advance toward improved consistency of MRS data in neuroscience and can be utilized for multi-session and longitudinal studies.

Abstract
Background Data exist of the benefits of antifibrinolytics such as tranexamic acid (TXA) in general spine surgery. However, there are limited data of its use in oncological spine patients. Methods A systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed, Cochrane, OVID, and Embase databases were searched. Search terms: "tranexamic acid", "aprotinin," "aminocaproic acid," "spine surgery," "spine tumors," and "spine oncology." Included studies were full text publications written in English with patients treated with either agent or who had surgery for oncological spine disease (OSD). Results Seven hundred results were reviewed form the different databases, seven were selected. A total of 408 patients underwent spine surgery for OSD and received antifibrinolytics. There was a male predominance (55.2%) and mean age ranged from 43 to 62 years. The most common tumor operated was metastatic renal cancer, followed by breast and lung. Most studies administered TXA as a bolus followed by an infusion during surgery. Median blood loss was of 667 mL (253.3-1480 mL). Patients with TXA required 1-2 units less of transfusion and had 56-63 mL less of postoperative drainage versus no TXA. The median incidence of deep venous thrombosis (DVT) was 2.95% (0-7.9%) and for pulmonary embolism (PE) was 4.25% (0-14.3%). The use of TXA reduced intraoperative blood loss, transfusions and reduced postoperative surgical drainage output compared to no TXA use in patients with OSD. Conclusion In this review, we found that TXA may diminish intraoperative blood loss, the need for transfusion and postoperative drainage from surgical drains when used in OSD without major increase in rates of DVT or PE.

of product attributes and marketing stimuli. FOOD RESEARCH 2022. [DOI: 10.26656/fr.2017.6(6).861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/29/2022] Open
Abstract
The Halal market in the United Kingdom is worth $4.5 billion and is anticipated to grow
at a rate of 5% each year. In the United Kingdom, there is a growing demand for Halal
food, which has resulted in the formation of various unregulated Halal Certification
Bodies. In the halal food market, the problem of halal authenticity has recently become a
serious concern. The purpose of the paper was to determine the effect of product attributes
and marketing stimuli on customer attitudes toward halal food among Muslim customers
in the U.K. A cross-sectional study was adopted for this study. The sample of the study
included the Muslim customers who have consumed halal food in the U.K. The authors
used a survey method to collect the quantitative data. A total of 384 responses were
received and data were analysed using SPSS. The findings of the study revealed that
product attributes such as country of origin have a significantly greater influence on the
customer attitude towards halal food compared to other product attributes. The findings
further showed that marketing stimuli such as sales’ location impact on customer attitude
however advertisement did not have any impact on customer attitude towards halal food.
The finding held perspectives from Muslim customers in the U.K and contributes to the
stimulus-organism-response theory by incorporating product attributes and marketing as
stimulus factors that affect the internal psychological state i.e., customer’s attitude in the
case of the U.K. The implication of this study was to recommend Halal enterprises import
halal food from Islamic countries for U.K customers, research the strategic location and
select the hypermarkets, that handle halal food with care.

Abstract
Abstract
Background
Complex pulmonary atresia with a ventricular septal defect and major aortopulmonary collateral arteries (PA VSD MAPCA) is a rare and complex form of congenital heart disease. Staged surgical palliation is carried out in childhood, and in expert centres, is associated with good medium term survival. Adult outcomes following transition to adult care are not known.
Purpose
To establish adult outcomes of PA VSD MAPCA following repair during childhood in our institution
Methods
Review of clinical records for outcome data including life status, NYHA class, employment status, re-intervention in adult life, arrhythmia, pregnancy, exercise capacity and mode of death, where known. We predefined our population into two groups based on their status at transition to adult care, A) complete repair with RV-PA conduit and VSD closed and B) repaired but VSD left open.
Results
188 patients from our series have transitioned to adult services. As many were tertiary referrals (nationally and internationally) the local follow up population was 53 adults (54.7% male), mean age of those alive under follow up is 27.2±6.5 years, with a mean follow up of 25.3±6.1 years. There were 43 in group A and 10 in group B. Mortality in the total population was 18.9% (10/53), group A (16.3%), group B (30.0%), mean age at death 37.5±10.3 years and 29.9±8.4 years, 6/10 deaths were sudden. 22.6% of the whole group had DiGeorge/22q11 microdeletion, with a learning deficit in 32.7% of the cohort, where this could be assessed. Reinterventions included RV-PA conduit change, coil occlusion, pacemaker implantation, ICD implantation and ablation procedures, overall 39.6% underwent reintervention in adult life. Pregnancy occurred in 33.3% of 24 female patients. 50% of individuals were found to have undertaken some form of paid work and of these 11.5% had DiGeorge.
Conclusions
Complex PA VSD MAPCA is associated with good late survival with late attrition including sudden death and heart failure. 22q11 is associated with learning deficit and consequent lack of employment. Non 22q11 have good educational outcomes and there is less observed deficit regarding employment. Successful pregnancy is possible within this population.

Abstract
Abstract
Background
There is limited literature available on the impact of myocardial ischemia but no obstructive coronary arteries (INOCA) on patients' lives.
Purpose
We sought to determine how INOCA impacts the physical, social, and mental health of persons with this diagnosis.
Methods
A survey was made available to all members of the patient support group from INOCA International over a 3-month time period. Fitness was estimated using the Duke Activity Status Index (DASI), assessing levels of activities performed prior to the onset of INOCA symptoms, and after the diagnosis of INOCA. The formula to estimate fitness in metabolic equivalents (METs) = 0.43 × DASI + 9.6 / 3.5
Results
A total of 297 patients with INOCA responded to the survey; 91.2% were women. The most common diagnosis was coronary microvascular dysfunction (64.3%) and coronary artery spasm (50.5%) (Table 1). 34.4% reported living with symptoms for ≥3 years before their diagnosis of INOCA was made. 77.8% who had been told their symptoms were not cardiac. The symptoms the respondents experienced were numerous, but 92.9% reported symptoms of chest pain, pressure, or discomfort. Fitness levels prior to the onset of INOCA symptoms were significantly higher compared to after diagnosed with INOCA (8.6±1.8 METs vs 5.6±1.8 METs; P<0.0001). Most respondents reported an adverse impact on their home life (80.5%), social life (80.1%), mental health (70.4%), outlook on life (69.7%), sex life (55.9%), and their partner/spouse relationship (53.9%). Work life was also affected once living with INOCA: approximately three-quarters had reduced their work hours or stopping work completely, 47.5% retired early, and 38.4% applied for disability. While living with INOCA, for each 1-MET decrease in fitness, there was a loss of 3.0±0.6 days/months of physical health, 1.8±0.6 days/month of mental health, and 2.9±0.7 days/months of inability to perform recreational activities (p<0.0001) (Figure 1).
Conclusions
Living with INOCA has significant impact on physical, mental and social health. Significant physical fitness declines are seen in those living with INOCA and are lower in those experiencing any adverse impact of living with INOCA. Additionally, the impact of INOCA on the ability to work has important economic consequences to both the patient and society. Increased recognition of the impact of INOCA on these aspects of health need to be recognized and further work is needed to better diagnosis and treat the symptoms of INOCA to improve the quality of life, cardiovascular outcomes, and overall health of this frequently encountered cardiovascular disorder.

Abstract
Well established and common practice in conservative management of omphalocele major is escharotics therapy with different topical agents. Among them mercurochrome, alcohol, silver salts, povidone iodine, acacia nilotca paste are commonly used. It is a comparative study between application of acacia nilotica paste and povidone iodine solution as a primary non surgical treatment of omphalocele major regarding efficacy and safety of these two topical agents. A double blind randomized controlled study was conducted at the department of Paediatric Surgery, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from July 2016 to June 2019. In this study 20 cases of omphalocele major and randomly divided into two equal groups. Group A and Group B treated with acacia nilotica paste and povidone iodine solution respectively. Gastroschisis, ruptured-omphalocele major or omphalocele minor excluded in this study. The size of the fascial defect in cm, time required for full oral feeding tolerance and duration of hospital stay were evaluating parameters. Patients with Group A tolerated full oral feeding earlier, shorter total hospital stay duration and low mortality rate than those from Group B. Application of acacia nilotica is a safe and effective treatment of omphalocele major regarding rapid full oral feeding tolerance, shorter hospital stay and low mortality rate.

Abstract
BACKGROUND Multidisciplinary spine conferences (MSCs) are a strategy for discussing diagnostic and treatment aspects of patient care. Although they are becoming more common in hospitals, literature investigating how they impact patient care and outcomes is scarce. The aim of this study is to examine the impact of MSCs on surgical management and outcomes in elective spine surgical care. METHODS A systematic review of the literature was conducted to evaluate the impact of MSCs on patient management and outcomes. PubMed and Cochrane databases were searched using combinations and variations of search terms "Spine Conferences," "Multidisciplinary," and "Spine Team." RESULTS The literature search yielded 435 articles, of which 120 were selected for full-text review. Four articles (N = 529 patients) were included. Surgical plans were discussed in 211 patients. The decision was altered to conservative treatment in 70 patients (33.17%) and a different surgical strategy in 34 patients (16.11%). The differences were significant in 2 studies (P < 0.05). A 51% reduction in 30-day complications rates was observed when MSC was implemented in patients with adult complex scoliosis. Other spinal disorders showed a 30-day complication rate between 0% and 14% after MSC. CONCLUSIONS To our knowledge, this is the first systematic review of outcomes of MSCs in elective spine surgery and it confirms that MSCs impact management plan and outcomes. Consistent MSCs that include surgeons and nonsurgeons have the potential to enhance communication between specialists, standardize treatments, improve patient care, and encourage teamwork. More analysis is warranted to determine if patient outcomes are improved with these measures.

Abstract
Aim The aim of surgical training is to ensure trainees acquire competencies to perform as a Day 1 Consultant. The last decade has seen the introduction of European Working Time Directive, NELA guidelines and the revised Junior Doctor Contract. All of these, as well as the COVID 19 pandemic, have caused concerns regarding training. Our aim was to examine any changes to night-time on call activity during this time. Method We retrospectively analysed prospectively collected data from 2011, 2018, and 2021, in a busy District General Hospital. The data collection period was 31 days, looking at night-time (8pm to 8am) operative experience, supervision, and non-operative activity. A regression analysis was conducted to compare outcomes. A qualitative survey was used to assess attitudes and confidence. Results On average, trainees spent 11% of their time operating independently, 2% operating supervised, 11% attending trauma-calls and 73% clerking/non-educational activities. There was a significant difference between the hours spent on operative versus non-operative activity (P 0.00046) with no differences over the years. Junior trainees did not feel confident operating at night and only 33% of all trainees found night-time training effective. Conclusions Nightshifts comprise a substantial proportion of potential training opportunities and managing the unselected emergency take is one of the Capabilities in Practice. Effective solutions must be implemented to help improve night-time surgical experience and confidence in order for this time to be effective for training of both operative and non-operative competency attainment.

Abstract
Vaccination is not only a medical term rather it is framed under socio-cultural perspectives and debates as well. Human history is full of illnesses caused bacteria and viruses killing millions of people including children and adults. Technological development in the health sector enabled to combat pathogenic illnesses through different methods whereby vaccination is one of them. However, it is a dilemma that vaccination has faced many barriers including logistical but most importantly sociocultural and religious. In 2019, WHO revealed vaccine hesitancy as a leading threat to health throughout the globe even in the top 10. This study looks to analyze peer reviewed literature to explore barriers to vaccination. Methodologically, this is desk research and systematic review. Numerous databases were searched with key words and purposively studies were selected for this study. A total of 17 most relevant studies were sampled. Findings show that there are four major factors hindering vaccination. 1st cultural and ethnic background matters whereby religion and the belief system are predominant factors. 2nd awareness and educational variables are also there, for instance, it is noted that many people are not aware of vaccination process specifically in case of HPV vaccination. 3rd social media plays a pivotal role whereby misinformation internalizes negative attitudes and misperceptions about vaccines. 4th social media is a key dimension whereby disinformation and misinformation are communicated through platforms whereby some are intentionally circulated. It is suggested that culturally relativism perspective can be helpful in increasing vaccination percentages. It pertains to intervention through culturally approved methods, for example, sensitizing the ethnic backgrounds through their leadership. In addition, vaccination tracking, media campaigns, focus on school level education to include health related course can be helpful.

Abstract
Background: Dropped head syndrome (DHS) is uncommon and involves severe weakness of neck-extensor muscles resulting in a progressive reducible cervical kyphosis. The first-line management consists of medical treatment targeted at diagnosing underlying pathologies. However, the surgical management of DHS has not been well studied. Methods: Here, we systematically reviewed the PubMed and Cochrane databases for DHS using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. All relevant articles up to March 31, 2022, were analyzed. The patient had to be ≥18 years with DHS and had to have undergone surgery with outcomes data available. Outcomes measurements included neurological status, rate of failure (RF), horizontal gaze, and complications. Results: A total of 22 articles selected for this study identified 54 patients who averaged 68.9 years of age. Cervical arthrodesis without thoracic extension was performed in seven patients with a RF of 71%. Cervicothoracic arthrodesis was performed in 46 patients with an RF of 13%. The most chosen upper level of fusion was C2 in 63% of cases, and the occiput was included only in 13% of patients. All patients neurologically stabilized or improved, while 75% of undergoing anterior procedures exhibited postoperative dysphagia and/or airway-related complications. Conclusion: The early surgery for patients with DHS who demonstrate neurological compromise or progressive deformity is safe and effective and leads to excellent outcomes.

Abstract
The current study is to analyze the causes of militancy, terrorism, and radicalization where multifarious factors are contributing towards spreading such behavior. However, the study is delimited to focus on the economic factors, including poverty, unemployment and other such factors that lead towards militancy, terrorism, and radical behavior in society. The field information was collected from 200 respondents using purposive sampling technique with stratified approach from 3 strata of the society including businessmen, teachers and clergy or religious class of age 20 and above. The data was collected through a structured interview schedule, and the analysis was made in the form of tables, discussion and the findings have been verified through chi-square test. The findings show that militancy, terrorism, and radicalization have their roots in deep rooted poverty, unemployment, and lack of other life facilities in the area. The study suggests proper planning for provision of jobs, equal distribution of resources among people and provision of life facilities to the masses.

Abstract
BackgroundUpadacitinib (UPA) was previously evaluated in two Phase 2, randomized, controlled trials (RCTs) in patients (pts) with rheumatoid arthritis (RA) and inadequate response to tumor necrosis factor inhibitors (BALANCE-1) or methotrexate (BALANCE-2).ObjectivesTo assess the final safety and efficacy of UPA in BALANCE-EXTEND, a 312-week open-label extension (OLE) enrolling pts who completed either BALANCE-1 or BALANCE-2.MethodsAll pts initially received UPA 6 mg twice daily (BID). Increase to 12 mg BID was required for pts with <20% improvement in swollen or tender joint counts (S/TJC) at Week 6 or 12, and permitted for those not achieving Clinical Disease Activity Index (CDAI) low disease activity (LDA). Pts with <20% improvement in SJC or TJC 6 weeks after escalation, or at any two consecutive visits, discontinued. Return to 6 mg BID was permitted for safety or tolerability reasons. After January 2017, the 6 and 12 mg BID doses were replaced by 15 and 30 mg once-daily (QD) extended-release equivalents. As-observed efficacy data are shown at Week 312 for three subgroups: pts who received 6 mg BID/15 mg QD throughout (“Never titrated”), those titrated up to 12 mg BID/30 mg QD for efficacy (“Titrated up”), and those titrated up to 12 BID/30 mg QD and then back to 6 mg BID/15 mg QD due to safety concerns (“Titrated up and down”). Exposure-adjusted adverse events (EAERs) per 100 patient-years (PY) of exposure were summarized from OLE Day 1 in all pts who received UPA (Any UPA).ResultsOverall, 493 pts entered the OLE, receiving UPA for ≤6.2 years (Never titrated, n=306; Titrated up, n=149; Titrated up and down, n=38), and 270 pts (54.8%) discontinued, mostly due to withdrawal of consent (16.8%; n=83) or AEs (14.6%; n=72). Mean (standard deviation) duration of UPA exposure was 3.8 (2.4) years (range <1–6.2 years); cumulative exposure was 1863 PY. The AE profile in pts receiving UPA 15 mg was generally similar to the Any UPA population, and to that observed in the Phase 3 UPA 15 mg clinical trial population (Table 1). Efficacy was maintained to Week 312, with 84.5% and 86.6% of pts in the Never titrated group achieving DAS28-CRP ≤3.2 and CDAI LDA, respectively (Figure 1).Table 1.Summary of AEs in pts who received UPA 6 mg BID/15 mg QD in the OLE and in the UPA 15 mg Phase 3 study programBALANCE-EXTEND (UPA 6 mg BID/15 mg QD)UPA 15 mg – Phase 3 programbEvents/100 PY (95 CI)aEvents/100 PY (95% CI)aN=493, PY=1277N=3209, PY=9079Any AE138.4 (132.0, 145.0)205.5 (202.5, 208.5)Any SAE7.9 (6.4, 9.6)12.4 (11.7, 13.2)AE leading to discontinuation4.2 (3.2, 5.5)4.9 (4.4, 5.3)Death0.4 (0.1, 0.9)0.5 (0.4, 0.7)cInfection49.2 (45.5, 53.2)63.9 (62.3, 65.6) Serious infection1.4 (0.8, 2.2)2.8 (2.4, 3.1) Opportunistic infection0.2 (0.0, 0.6)0.3 (0.2, 0.4) Herpes zoster2.0 (1.3, 3.0)3.0 (2.6, 3.3)Anemia1.1 (0.6, 1.8)3.0 (2.7, 3.4)Neutropenia1.3 (0.8, 2.1)2.1 (1.8, 2.5)Lymphopenia1.7 (1.1, 2.6)1.7 (1.4, 1.9)Gastrointestinal perforation0<0.1 (0.0, 0.1)Any malignancy1.2 (0.7, 1.9)1.1 (0.9, 1.4)Non-melanoma skin cancer (NMSC)0.4 (0.1, 0.9)0.4 (0.3, 0.5) Excluding NMSC0.8 (0.4, 1.4)0.7 (0.6, 0.9)Creatinine phosphokinase elevation3.4 (2.5, 4.6)4.4 (4.0, 4.9)Hepatic disorder4.1 (3.0, 5.3)10.2 (9.5, 10.8)Venous thromboembolism0.5 (0.2, 1.0)0.4 (0.3, 0.6)Major adverse cardiovascular event0.5 (0.2, 1.0)0.4 (0.3, 0.5)aMultiple events occurring in the same pts are counted in the calculation of events/100 PY. bCut-off, June 30, 2021. cBased on 9080 PY.ConclusionIn this OLE, UPA treatment over ~312 weeks showed sustained long-term efficacy in pts with RA who had completed Phase 2 RCTs.

Abstract
BackgroundScleroderma, also known as Systemic Sclerosis (SSc), is a connective tissue disease that affects multiple organ systems, including the cardiovascular and respiratory systems, namely, pulmonary arterial hypertension (PAH) and interstitial lung disease (ILD) as the leading causes of death in this patient population.ObjectivesThe purpose of this study is to determine the prevalence of PAH and ILD in a cohort of patients diagnosed with SSc.MethodsWe performed a retrospective chart review of clinical characteristics of all patients diagnosed with SSc Cleveland Clinic Abu Dhabi between April 2015 and April 2020. PAH was estimated by echocardiographic findings and diagnosed based on right heart catheterization (RHC) using 2019 World Symposium on Pulmonary Hypertension. The CT scan of the chest was read by a board-certified radiologist in chest radiology.ResultsFifty individuals were diagnosed with SSc, with 46% having diffuse cutaneous systemic sclerosis and 54% having limited cutaneous systemic sclerosis. The majority of the patients (88%) were female, with a mean age of 41 ±13 years. The average period from presentation to diagnosis was 5 ±5.4 years. The majority of the cohort (86%) were from the United Arab Emirates. The average BMI was 26.0 kg/m2. Patients’ most prevalent symptoms are fatigue (80%), gastrointestinal symptoms (72%) followed by shortness of breath (58%) and cough (50%). Twenty-six out of fifty patients (52%) underwent a CT chest scan, with 19 (38%) having ILD. Eight patients had more than 30% fibrotic alterations, four patients had 10-30% fibrotic changes, and seven patients had less than 10% fibrotic abnormalities. Patients with more than 10% fibrotic changes were more likely to have usual interstitial pneumonia, whereas those with less than 10% fibrotic changes were more likely to have none specific fibrosis. The majority of patients (92%) had echocardiogram. All except one patient had a normal ejection fraction, and five had grade 1 left ventricular diastolic dysfunction. Five patients were described as having mild, 1 moderate and 2 severe PAH. Only 4 patients underwent RHC. One patient had group II PAH based on elevated wedge pressure. One had group 1 PAH with systemic sclerosis as the only cause for her PAH and two patients had group III PAH due to having more than 30 % pulmonary fibrosis and severe restrictive defect on spirometry. Therefore, the precapillary PAH prevalence was 6% (3/50).ConclusionWhile the prevalence of pulmonary fibrosis in our SSc patients reflects what has been reported in the literature, the prevalence of PAH is significantly lower than the reported 15-20%.1 This is likely due to underdiagnosis of PAH considering the number of years of systemic sclerosis diagnosis on presentation to our clinic. A systematic approach is needed to assess for the presence and severity of PAH using tools as in Detect algorithm which has been validated and commonly used in Europe and North America to screen for PAH.2 Validation of such algorithm is likely needed in middle eastern population before it is universally adopted.References[1]Screening for pulmonary arterial hypertension in an unselected prospective systemic sclerosis cohort.

Abstract
BackgroundPatients (pts) with rheumatoid arthritis (RA) are often administered glucocorticoids (GCs) as bridging therapy when initiating or adjusting disease-modifying antirheumatic drugs (DMARDs). Due to their systemic effects, short-term use of GCs at the lowest possible dose is recommended with rapid tapering.1ObjectivesWe describe GC discontinuation patterns and the associated clinical outcomes in pts with RA receiving upadacitinib (UPA) or adalimumab (ADA).MethodsSELECT-COMPARE is a randomized phase 3 trial of UPA vs placebo and ADA with a 48-week (wk) double-blind treatment period and a 10-year long-term extension in pts with RA receiving concomitant methotrexate (MTX) who had an inadequate response to MTX.2 Background GCs (≤10 mg/day prednisone or equivalent) were permitted and could be tapered or discontinued starting at wk 26 per physician discretion. This post hoc analysis included pts who received ≥1 dose of UPA 15 mg once daily or ADA 40 mg every other wk while on concomitant GCs at baseline. The proportion of pts with disease worsening (Clinical Disease Activity Index [CDAI] >2 and Disease Activity Score 28-joint count C-reactive protein [DAS28-CRP] >0.6) following GC discontinuation through follow-up is described. Maintenance of clinical response, including remission and low disease activity based on CDAI ≤2.8 and ≤10, respectively, as well as DAS28-CRP <2.6 and ≤3.2, were assessed among pts who discontinued GCs. Adverse events (AEs) were assessed before and after GC discontinuation through follow-up. Data were analyzed descriptively.ResultsOf 1,629 pts randomized, 978 (60%) used GCs at baseline; 128 (13%) discontinued use at/after wk 26 (UPA, n=97; ADA, n=31). Baseline demographics and clinical characteristics were broadly similar between pts who continued or discontinued GCs. Median follow-up time after GC discontinuation was 60 wks for UPA and 84 wks for ADA. At the time of GC discontinuation, a numerically higher proportion of pts treated with UPA vs ADA were in disease control (CDAI ≤2.8: 55% vs 32%; CDAI ≤10: 85% vs 68%; DAS28-CRP <2.6: 71% vs 48%; DAS28-CRP ≤3.2: 87% vs 62%) (Table 1). Few pts receiving UPA experienced disease worsening following GC discontinuation (1% CDAI increase >2; 7% DAS28-CRP increase >0.6) and none on ADA (Table 1). At 6 months follow-up after GC discontinuation, most pts treated with UPA and ADA maintained CDAI ≤2.8 (74% vs 88%) and ≤10 (92% vs 95%) and DAS28-CRP <2.6 (89% vs 85%) and ≤3.2 (91% vs 94%), respectively (Table 1). GCs were reintroduced (albeit usually temporarily) in 14% of pts on UPA and 19% on ADA (Figure 1). AEs were generally similar across treatment groups. Rates of serious infection before and after GC discontinuation were 0.8 (95% CI 0.0–4.2) and 1.5 (0.2–5.4) events per 100 patient-years (E/100 PY) for UPA and 7.7 (1.6–22.4) and 0 E/100 PY for ADA, respectively. Interpretation of results is limited by small pt numbers and different exposure times.Table 1.Clinical outcomes of pts who discontinued GCs at/after wk 26n/N (%)Pts who discontinued GCs N=128UPAn=97ADAn=31CDAI≤10 at discontinuation79/93 (85%)21/31 (68%) Maintained at 6 months post discontinuationa61/66 (92%)18/19 (95%)≤2.8 at withdrawal51/93 (55%)10/31 (32%) Maintained at 6 months post discontinuationa32/43 (74%)7/8 (88%)Increase >2 any visit after withdrawal1/93 (1%)0DAS28-CRP≤3.2 at withdrawal78/90 (87%)18/29 (62%) Maintained at 6 months post discontinuationa58/64 (91%)15/16 (94%)<2.6 at withdrawal64/90 (71%)14/29 (48%) Maintained at 6 months post discontinuationa47/53 (89%)11/13 (85%)Increase >0.6 any visit after withdrawal6/92 (7%)0aAs a proportion of pts achieving outcome at GC discontinuation and with observed data 6 months post GC discontinuation.ConclusionIn pts who achieved disease control and discontinued GCs, disease control was maintained in almost all without worsening disease activity over time following GC discontinuation.ConclusionIn pts who achieved disease control and discontinued GCs, disease control was maintained in almost all without worsening disease activity over time following GC discontinuation.References[1]Smolen JS, et al.

Abstract
BACKGROUND Closed-loop insulin delivery systems have the potential to address suboptimal glucose control in children and adolescents with type 1 diabetes. We compared safety and efficacy of the Cambridge hybrid closed-loop algorithm with usual care over 6 months in this population. METHODS In a multicentre, multinational, parallel randomised controlled trial, participants aged 6-18 years using insulin pump therapy were recruited at seven UK and five US paediatric diabetes centres. Key inclusion criteria were diagnosis of type 1 diabetes for at least 12 months, insulin pump therapy for at least 3 months, and screening HbA1c levels between 53 and 86 mmol/mol (7·0-10·0%). Using block randomisation and central randomisation software, we randomly assigned participants to either closed-loop insulin delivery (closed-loop group) or to usual care with insulin pump therapy (control group) for 6 months. Randomisation was stratified at each centre by local baseline HbA1c. The Cambridge closed-loop algorithm running on a smartphone was used with either (1) a modified Medtronic 640G pump, Medtronic Guardian 3 sensor, and Medtronic prototype phone enclosure (FlorenceM configuration), or (2) a Sooil Dana RS pump and Dexcom G6 sensor (CamAPS FX configuration). The primary endpoint was change in HbA1c at 6 months combining data from both configurations. The primary analysis was done in all randomised patients (intention to treat). Trial registration ClinicalTrials.gov, NCT02925299. FINDINGS Of 147 people initially screened, 133 participants (mean age 13·0 years [SD 2·8]; 57% female, 43% male) were randomly assigned to either the closed-loop group (n=65) or the control group (n=68). Mean baseline HbA1c was 8·2% (SD 0·7) in the closed-loop group and 8·3% (0·7) in the control group. At 6 months, HbA1c was lower in the closed-loop group than in the control group (between-group difference -3·5 mmol/mol (95% CI -6·5 to -0·5 [-0·32 percentage points, -0·59 to -0·04]; p=0·023). Closed-loop usage was low with FlorenceM due to failing phone enclosures (median 40% [IQR 26-53]), but consistently high with CamAPS FX (93% [88-96]), impacting efficacy. A total of 155 adverse events occurred after randomisation (67 in the closed-loop group, 88 in the control group), including seven severe hypoglycaemia events (four in the closed-loop group, three in the control group), two diabetic ketoacidosis events (both in the closed-loop group), and two non-treatment-related serious adverse events. There were 23 reportable hyperglycaemia events (11 in the closed-loop group, 12 in the control group), which did not meet criteria for diabetic ketoacidosis. INTERPRETATION The Cambridge hybrid closed-loop algorithm had an acceptable safety profile, and improved glycaemic control in children and adolescents with type 1 diabetes. To ensure optimal efficacy of the closed-loop system, usage needs to be consistently high, as demonstrated with CamAPS FX. FUNDING National Institute of Diabetes and Digestive and Kidney Diseases.
