SMT-738: a novel small-molecule inhibitor of bacterial lipoprotein transport targeting Enterobacteriaceae. 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.

Consumer attitude toward Halal food in the case of the United Kingdom: the role
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
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
Abstract
Aims
Measure performance and cost effectiveness of a Virtual Consultation (VC) clinic, compared to face-to-face (FF) clinic, for 2-week-wait (2WW) colorectal cancer (CRC) referrals, which did not meet the criteria for nurse-led Telephone Assessment Service.
Methods
2WW CRC referrals were triaged by a colorectal surgeon to either a doctor-led VC or FF clinic. Demographics, referral indications, and primary outcome measures (time to clinic/results; investigation type; cancer detection rate) were compared pre-pandemic (November 2019–January 2020) and during the pandemic (May–June 2021).
Results
158 (pre-pandemic) and 160 (pandemic) consecutive patients were analysed, with no difference in age (74 vs. 75 years, p=0.936). During the pandemic, patients were referred with an increased number of positive FIT tests (29 vs. 13%, p<0.001), were more likely to have computerised tomography (65 vs. 45%, p=0.003), had a longer time from referral to clinic assessment (10 vs. 8 days, p=0.002), but were informed of results more promptly (59 vs. 138 days, p<0.001) than pre-pandemic patients. During the pandemic patients were assessed earlier via VC than FF clinics (9 vs. 11 days, p=0.049). There were no significant differences in cancer detection rate pre or during the pandemic (12 vs. 8%, p=0.187), or between VC and FF clinic during the pandemic (6 vs. 12%, p=0.294). Cost effective analysis showed £15,000 per annum saving with doctor-led VC clinic.
Conclusion
Virtual consultation for 2WW CRC referrals may improve efficiency without compromising the cancer detection rate, as well as reducing risk of Covid-19 transmission and being more cost effective.

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
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.

Cambridge hybrid closed-loop algorithm in children and adolescents with type 1 diabetes: a multicentre 6-month randomised controlled trial. Lancet Digit Health 2022; 4:e245-e255. [PMID: 35272971 DOI: 10.1016/s2589-7500(22)00020-6] [Citation(s) in RCA: 28] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 12/10/2021] [Accepted: 01/25/2022] [Indexed: 02/07/2023]
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.

Abstract
This study explores the antioxidant activity, phytochemical screening, total phenolic and flavonoids contents in the extracts of four locally available weeds plants namely Convolvulus arvensis, Chenopodium murale, Avena fatua and Phalaris minor with different solvents. The antioxidant activities of these extracts were determined via various in-vitro methods such as total antioxidant activity (TAA), reducing power (RP), DPPH (2,2-Diphenyl-1-Picrylhydrazyl) free radical scavenging and hydrogen peroxide scavenging assays. Phytochemical screening was performed both qualitatively as well as quantitatively. Total phenolic content (TPC) and total flavonoid content (TFC) were determined through Folin- Ciocalteu reagent and aluminium chloride methods respectively. Methanol-chloroform solvent showed the presence of a high amount of TPC in milligram of gallic acid equivalent per gram of dry weight (mg of GAE/g of DW) in the extracts of all weeds. Their descending sequence was Avena fatua (74.09) ˃ Phalaris minor (65.66) ˃ Chenopodium murale (64.04) ˃ Convolvulus arvensis (61.905), while, chloroform solvent found to be best solvent for the extraction of TFC. Methanol-chloroform solvent was also found to be best solvent for TAA (Total antioxidant activity assay) which showed values in milligram of ascorbic acid equivalent per gram of dry weight (mg of AAE /g of DW), for DPPH scavenging activity, reducing power (antioxidant activity) and hydrogen peroxide scavenging activity. Phytochemical screening indicated the presence of polyphenols, flavonoids, tannins, saponins, alkaloids and glycosides in these weeds.

Abstract
Castleman Disease (CD) is a rare entity that typically presents as an enhancing nodal mass in the mediastinum or head and neck region on computed tomography (CT). It may manifest as unicentric or multicentric regions of lymph node enlargement. A key clinical issue in the context of CD is delayed diagnosis, which contributes adversely to patient outcome, given that accurate diagnosis facilitates earlier treatment of this curable disease. This article will address relevant imaging aspects, with reference to typical and atypical imaging features of CD, illustrated using examples from our specialist centre; the imaging journey for patients with CD; and will provide practical pointers to radiologists in differentiating CD from other benign and malignant causes of enhancing lymphadenopathy, including lymphoma and neoplastic adenopathy. We will also review current classification tools and staging challenges with reference to World Health Organization guidelines, International Working Group guidelines as well as the Lugano classification. Finally, we will discuss the potential role of additional imaging techniques in CD, highlighting novel imaging methods and expanded utilities from our specialist centre.

Introduction
Coronary artery disease continues to be the leading cause of death in patients with stage IV-V chronic kidney disease (CKD IV-V). However, the prognosis and early outcomes for advanced CKD patients undergoing coronary artery bypass grafting (CAB) worsen as the estimated glomerular filtration rate (eGFR) deteriorates. Therefore, we compared postoperative clinical outcomes and troponin trends in patients having advanced CKD according to preoperative dialysis status in a single centre experience.
Methods
A total of 51 patients with CKD IV and V who underwent CAB between 2016-2021 were included in the study. Data on patient characteristics and postoperative outcomes were collected retrospectively, and independently for our Society of Thoracic Surgeons database. Characteristics were compared between patients having CKD IV vs. CKD V. The differences in postoperative cardiac troponin trends and outcomes were evaluated between patients who did vs. did not undergo preoperative dialysis. The statistical analysis was conducted applying appropriate parametric or non-parametric (for skewed variables) testing methods, and a p value < 0.05 was considered to be statistically significant.
Results
47% (24) of subjects had CKD IV, while the rest featured CKD V. Patients with CKD IV tended to be older (61.8 ± 9.2 vs. 56.3 ± 11.5 years, p = 0.07), more obese (BMI: 31.4 ± 6.8, 27.4 ± 4.9 kg/m2, p = 0.02) and had significantly higher preoperative GFR (23 ± 4.9 vs. 9 ± 3.3 mL/min, p < 0.001) (Table.1). When comparing patients who underwent preoperative dialysis vs. those who did not, troponin levels were the highest at 18h postoperative in both groups, however, troponin levels were comparable between both groups at all time points (Table.2). Although, there was no difference in hospital length of stay and mortality between these groups, patients who did not undergo preoperative dialysis had longer intensive care unit length of stay (ICU LOS).
Conclusion
In this single centre experience preoperative dialysis was not associated with a significant difference in trends of postoperative cardiac enzymes. Although preoperative dialysis was associated with shorter ICU LOS, complex pre-procedural surgical risk assessment remains paramount in reducing complications and mortality in this high-risk population.

Abstract
Tramadol is a bitter atypical opioid analgesic drug and is prescribed to treat postoperative pain in children. However, in many countries there is no licensed paediatric tramadol formulation available. We have formulated a novel chewable chocolate-based drug delivery system for the administration of tramadol to children. This pilot, single-centre, open-label, randomised clinical study assessed the taste tolerability and comparative population pharmacokinetics of the novel tramadol chewable tablet against a compounded tramadol hydrochloride oral liquid, at a dose of 1 mg.kg-1 . A 5-point facial hedonic scale was used by the children, parents and nurses to assess tolerability. One hundred and forty-one children aged 3-16 years were given tramadol 30 min before general anaesthesia. Blood samples were taken following the induction of anaesthesia and for up to 5 h following tramadol administration. Tramadol and its active metabolite O-desmethyltramadol were analysed using reversed-phase high-performance liquid chromatography. A population pharmacokinetic model was built using non-linear mixed effects modelling. The relative bioavailability for the tablet was 1.25 times higher (95%CI 1.16-1.35) than for tramadol hydrochloride oral liquid, while the absorption rate constant for the tablet was significantly lower (1.97 h-1 vs. 3.34 h-1 , p < 0.001). Larger inter-individual variability in absorption rates were observed with the liquid tramadol. The tramadol chewable tablet was more acceptable in taste to children when assessed by the children, parents and nurses (all p < 0.001). We conclude that the novel tramadol chewable tablet has favourable acceptability and more reliable relative bioavailability in children compared with tramadol hydrochloride oral liquid.

Abstract
This study was aimed to investigate Carbofuran (CF)-induced pathological changes in cattle egret. Two hundred cattle egrets were reared and equally divided into four groups and given different CF concentrations (0.03 mg/L, 0.02 mg/L, 0.01 mg/L and 0 mg/L (control group)). Hematology, serum biochemistry, histopathology, and immunological markers were studied. Our results confirm that CF induces anemic conditions, leukocytosis, elevated liver enzymatic activity, and alterations in renal biomarkers. Moreover, specific microscopic lesions such as multifocal necrosis, pyknotic nuclei, hemorrhages, congestion, and inflammatory cell proliferation were observed in the liver, kidney, spleen, and thymus. These findings suggest that CF can induce harmful effects, so the application of this pesticide in the field must be strictly monitored to mitigate the possibility of exposure to non-target species.

Abstract
Life cycle assessment was carried out for a conventional wooden furniture set produced in Mardan division of the Khyber Pakhtunkhwa province of Pakistan during 2018-19. Primary data regarding inputs and outputs were collected through questionnaire surveys from 100 conventional wooden furniture set manufacturers, 50 in district Mardan and 50 in district Swabi. In the present study, cradle-to-gate life cycle assessment approach was applied for a functional unit of one conventional wooden furniture set. Production weighted average data were modelled in the environmental impacts modelling software i.e., SimaPro v.8.5. The results showed that textile used in sofa set, wood preservative for polishing and preventing insects attack and petrol used in generator had the highest contribution to all the environmental impact categories evaluated. Total cumulative energy demand for wooden furniture set manufactured was 30,005 MJ with most of the energy acquired from non-renewable fossil fuel resources.

Abstract
Vitamin K acts a cofactor for the gamma-carboxylation of several proteins in the coagulation cascade. The clinical spectrum of vitamin K deficiency (VKD) can be asymptomatic to a significant bleeding. VKD is classically seen in newborns. However, this can manifest later in patients with risks such as sub-optimal nutrition, fat malabsorption, medications including antibiotics. A 17-year-old male with spinal muscular atrophy (SMA) Type 1, tracheostomy with ventilator dependent, gastrostomy tube feeding was seen by the gastroenterologist following treatment for small intestinal bacterial overgrowth (SIBO). Investigations showed coagulopathy following which he was transferred to the Pediatric ICU. Labs revealed prothrombin time (PT) 114 s [Normal 9.4-12.5 s], INR (International normalized ratio) 12.6 [Normal < 1.1] and partial thromboplastin time (PTT) 90 s [Normal 25.1-36.5 s]. Mixing studies and coagulation assays were consistent with VKD (low Factor VII and Factor IX with normal Factor V). His home blenderized feeding regimen met the caloric requirement but not the adequate intake (AI) values for vitamin K and other minerals. He received intravenous vitamin K (phytonadione) for five consecutive days with resolution of the coagulopathy (PT 13.2 s, PTT 37.1 s, INR 1.2). The patient was discharged on enteral vitamin K and additional supplements following dietary review by a nutritionist. Clinicians should be cognizant of VKD in patients on blenderized tube feeds which may not meet the adequate intake (AI) goals. In patients who are not receiving nutritionally complete formulas or receiving inadequate volumes, it is important to monitor macro and micronutrients.

The experiment was conducted in ten happas installed in earthen ponds, each stocked with 10 fishes for 90 days. Four commercial fish feeds having 25%, 30%, 32% and 40% crude protein (CP) levels were fed to fish at 3% of their wet body weight three times a day. The results of the study revealed that highest weight gain, feed conversion ratio and survival rate were observed in 30% protein feed. Meanwhile, moisture content was higher in fish fed with 30% CP feed while highest crude protein was recorded in 40% CP fed fish. Lowest fat content was observed in 32% CP feed. Amino acid profile of fish revealed better results in 30% CP feed. Total protein, glucose and globulin were also highest in fish feeding 30% CP feed, while albumin was highest in 40% CP feed. It is concluded that 30% CP feed showed better results in terms of growth, amino acid profile and serological parameters without effecting fish body composition.

Purchase intention towards dietary supplements during COVID-19 pandemic:
consumers’ perspective. FOOD RESEARCH 2021. [DOI: 10.26656/fr.2017.5(5).270] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/12/2022] Open
Abstract
The consumption of dietary supplements (DSs) has been steadily increasing in the wake of
the COVID-19 outbreak in most countries. Consumer purchase intention towards DSs is
expected to be of concern to many companies in the pharmaceutical industry. This study
extends the Theory of Planned Behaviour by adding health consciousness and perceived
price in the model to investigate its effect on consumer purchase intention towards DSs
during the COVID-19 outbreak. A questionnaire-based survey was distributed via an
online survey to 207 respondents. Results from multiple regression analysis revealed that
consumer attitudes, subjective norms, perceived behavioural control, and health
consciousness contributed significantly to purchase intention towards DSs. Perceived
price did not have an impact on intention. Further investigation revealed that favourable
attitudes towards DSs were the most important contributor towards purchasing DSs during
the COVID-19 pandemic.

Abstract
The study was conducted to evaluate the effect of Moringa olifera on the growth and gut health of Tilapia (Oreochromis niloticus). The feed having 30% crude protein was prepared as an experimental diet with 4%, 8% and 10% M. olifera leaf supplementation, respectively. The control diet was devoid of M. olifera leaves. The 10 weeks feeding trial was carried out on 60 fish in aquaria. Fish was fed @ 3% of body weight twice a day. Diet with the high level of inclusion of M. olifera leaves significantly increased the growth rate, Survival Rate (SR), Specific Growth Rate (SGR) and Feed Conversion Efficiency (FCE) in all treatment groups compared to the control group. Similarly, Feed Conversion Ratio (FCR) gradually decreased and found highly-significant. To check the gut health of the Tilapia, random samples were selected and dissected. Nutrient agar was used as culture media to check the growth of bacteria. Pour Plate Method was used for viable colonies count by colony counter. Through staining method, the different bacteria such as Escherichia coli, Salmonella, Shigella and Pseudomonas aeruginosa were identify abundantly in the intestine of control diet fish but less number present in treatment diets groups. These results showed that M. olifera leaves up to 10% of dietary protein can be used for Nile tilapia for significant growth and healthy gut microbiota of fish.

Abstract
Abstract
Background
High intensity statins are recommended in patients with acute coronary syndrome. Statins inhibit atherosclerotic plaque formation in the coronary arteries and reducing the burden of ischemic heart disease, therefore decreasing the morbidity and mortality. Muscle symptoms are most common adverse effect of statins. Hence, the aim of this study is to determine the statin induced myalgia by the statin myalgia clinical score.
Purpose
To monitor the Statin induced myalgia on high intensity statin in patients with Acute Coronary Syndrome
Methods
This was an prospective observational study comprised of 418 patients with acute coronary syndrome who were commenced on high intensity statins (Rosuvastatin 20–40mg & Atorvastatin 40–80). These patients were followed at 4 weeks, 8 weeks and 12 weeks subsequently and the clinical myalgia score (SAMS-CI) was calculated at each visit to determine the statin induced myalgia. SAMS-CI was categorized as unlikely (2–6), possible (7–8) and probable (9–11)
Results
From 418 patients, 327 were males and 91 were females. Mean age was 55.6±11.14. Only 19 (7.63±1.8) patients developed muscle symptoms on high intensity statins (Rosuvastatin 20 mg and Atorvastatin 40 mg) on SAMS-CI Score. 5 patients were unlikely to develop myalgia on SAMS-CI and continued with the same dosage without any new symptoms. 6 patients were possible on SAMS-CI, therefore the dosage of these patients were decreased to moderate intensity statin (Rosuvastatin 10mg, Atorvastatin 20 mg), their symptoms were resolved and continued with the moderate intensity statins. Furthermore, Statin was hold in 8 patients in the probable category for 4 weeks until the resolution of symptoms followed by moderate intensity statins.
Conclusion
Statin induced myalgia is more reported in old aged and female patients. Most of the patients can better tolerate the lower range of high intensity statins with the similar benefits and should be prescribed in every patient

Abstract
Introduction Pandemic COVID-19 necessitated a transformation in the delivery of healthcare. Telephone consultations were introduced to protect and progressively manage patients with minimal delay. This is a review of the effectiveness of these remote consultations for suspected 2-week wait (2ww) head and neck cancer referrals to a north London NHS teaching hospital Oral and Maxillofacial unit during the first official UK government lockdown from March - July 2020. Method Prospective electronic records of 176 consecutive 2ww referrals between March – July 2020 was assessed. Data analysed included initial telephone consultations, subsequent face-to-face (F2F) appointments, if required, the interval from telephone to F2F appointments and histopathological diagnoses. Results 157 patients (n = 176) received an initial telephone call, of which 127 (80.9%) required a F2F consultation. The number of days between the initial telephone consultation and subsequent F2F assessment ranged from 0 to 141, with a mean of 11 and a median of 1. Notably, 31 patients (24.4%) were seen in person on the same day as their telephone consultation. Biopsies were indicated for 69 patients (54.3%) of which 9 (13.0%) were diagnosed as malignancies. Conclusions Whilst protecting patients from a pandemic is utmost, continuing care for non-pandemic conditions must be considered. It is even more important to manage 2ww referrals efficiently. These results indicate the majority of suspected cancer referrals warrant F2F assessment for a confident outcome. Despite reinstated, ongoing social restrictions, 2ww referrals are now being seen exclusively F2F, subject to patient choice. This information is useful for planning and strategizing services in a head and neck OMFS unit.

Abstract
Ninety days study was conducted in hapas installed in earthen ponds. Fish of an average initial weight (220g) were evenly distributed in triplicate groups within fifteen hapas. Five experimental diets labeled as T1 (25% CP and NRC recommended amino acid level) as control diet, T2 (with 2% low protein and 5% amino acid supplementation), T3 (with 2% low protein and 10% amino acid supplementation), T4 (with 4% low protein and 10% amino acid supplementation) and T5 (with 4% low protein and 20% amino acid supplementation) were prepared. Fish were fed with @3% of their body weight twice a day at 10.00 & 16:00 hour. Significantly higher percent weight gain (420.18 ± 66.84a) and specific growth rate (13499.33±1273.54a) along with improved feed conversion ratio (1.29 ± 0.09b) and hundred percent survivals were recorded during the trial. Furthermore proximate analysis of meat showed significant improvement in the crude protein level (81.77 ± 0.19a) served with diet containing 20% limiting amino acids mixture. Therefore, limiting amino acids can be a source of cost effective feed and use safely in L. rohita diet.

Abstract
Stunting is a significant public health problem in low- and middle-income countries. This study assessed the prevalence of stunting and associated risk factors of stunting among preschool and school-going children in flood-affected areas of Pakistan. A cross-sectional study was conducted by visiting 656 households through multi-stage sampling. Respondent's anthropometric measurements, socio-demographic information and sanitation facilities were explored. A logistic regression model was used to determine determinants of stunting, controlling for all possible confounders. The overall prevalence of stunting in children was 40.5%, among children 36.1% boys and 46.3% of girls were stunted. The prevalence of stunting in under-five children was 50.7%. Female children (OR=1.35, 95% CI:0.94-2.0), children aged 13-24 months (OR=6.5, 95% CI: 3.0-13.9), mothers aged 15-24 years (OR=4.4, 95% CI: 2.6-7.2), joint family (OR=2.1, 95% CI: 1.4-3.0) did not have access to improved drinking water (OR=3.3, 95% CI: 1.9-5.9), and the toilet facility (OR=2.8, 95% CI, 1.9-4.3), while the children from district Nowshera (OR=1.7, 95% CI: 0.9-3.2) were significantly (P<0.05) associated in univariate analysis. The regression model revealed that child age, maternal age, family type, quality of water, and toilet facility, were the significant (P<0.05) factors contributing to child stunting in the flood-hit areas. Identification of key factors might be helpful for policymakers in designing comprehensive community-based programs for the reduction of stunting in flood-affected areas. In disasters such as flood, the detrimental consequences of the stunting problem could be even more on children. Evidence-based education and care must be provided to the families in the flood-affected regions to reduce the stunting problem. The determinants of stunting should be targeted by making comprehensive policies regarding proper nutrition, livelihood, clean water, and sanitation facilities in flood-hit regions.

Abstract
Background:Upadacitinib (UPA) is an oral Janus kinase inhibitor approved for rheumatoid arthritis (RA). The safety and efficacy of UPA has been evaluated across a spectrum of patients (pts) with RA in the phase 3 SELECT clinical program.1,2Objectives:To describe long-term laboratory profiles (cutoff date: June 30, 2020) associated with exposure to UPA, adalimumab (ADA), and methotrexate (MTX) in pts with RA treated in the SELECT trials.Methods:Data were analyzed from 6 randomized controlled UPA RA trials.1,2 The proportions of pts experiencing potentially clinically significant laboratory changes at a single time point were summarized for the following groups: pooled UPA 15 mg once daily (QD; UPA15; 6 trials), pooled UPA 30 mg QD (UPA30; 4 trials), ADA 40 mg every other week (EOW; 1 trial), and MTX monotherapy (1 trial). Pts received UPA with/without background conventional synthetic disease-modifying antirheumatic drugs. Treatment-emergent adverse events are reported as exposure-adjusted event rates (events/100 pt-years [E/100 PY]). Toxicity was graded per OMERACT criteria, or NCI CTCAE for creatine phosphokinase (CPK) and creatinine.Results:4413 pts received ≥1 dose of UPA (UPA15, n=3209; UPA30, n=1204). Exposures were comparable between treatment groups (Table). Proportions of pts with Grade (Gr) 3 and 4 decreases in hemoglobin were highest with UPA30 and MTX (Table). Rates of anemia, as reported by the investigator, were comparable between UPA15, ADA, and MTX groups (Figure); the frequency of UPA-treated pts who discontinued due to anemia was low in all arms. Gr 3 and 4 decreases in neutrophils and lymphocytes with UPA were dose-dependent and higher vs ADA or MTX. Discontinuations due to neutropenia and lymphopenia were rare (<0.1%). Transaminase elevations were more frequent with UPA and MTX vs ADA; however, the proportion of pts who discontinued due to increases in alanine (ALT) or aspartate aminotransferase (AST) were comparable between UPA15 and ADA, and numerically higher with UPA30 and MTX. CPK elevations were more frequent with UPA (Figure). Most events were asymptomatic, and the 1 case of rhabdomyolysis in the UPA30 group was unrelated to study drug (attributed to influenza).Table 1.Pts with potentially clinically significant laboratory changesVariable, n (%)MTX monotherapy (n=314; 637.4 PY)ADA 40 mg EOW (n=579; 1051.8 PY)UPA 15 mg QD (n=3209; 7023.8 PY)UPA 30 mg QD (n=1204; 3091.6 PY)Mean (SD) exposure, weeks106 (67)95 (70)114 (64)134 (66)Median (range) exposure, weeks144 (1, 221)118 (2, 231)136 (0, 232)160 (0, 231)Hemoglobin, g/LGr 3 (70–<80 or decreased 21–<30)28a (9.0)24b (4.2)254d (7.9)169f (14.2)Gr 4 (<70 or decreased ≥30)16a (5.1)16b (2.8)101d (3.2)78f (6.5)Neutrophils, 109/LGr 3 (0.5–<1.0)3a (1.0)3b (0.5)40d (1.2)37g (3.1)Gr 4 (<0.5)1a (0.3)1b (0.2)10d (0.3)5g (0.4)Lymphocytes, 109/LGr 3 (0.5–<1.0)74a (23.7)53b (9.2)802d (25.1)423g (35.5)Gr 4 (<0.5)5a (1.6)3b (0.5)75d (2.3)47g (3.9)ALT, U/LGr 3 (3.0–8.0 × ULN)26a (8.3)13c (2.3)152e (4.8)71h (5.9)Gr 4 (>8.0 × ULN)5a (1.6)4c (0.7)26e (0.8)10h (0.8)AST, U/LGr 3 (3.0–8.0 × ULN)15a (4.8)9c (1.6)101e (3.2)36h (3.0)Gr 4 (>8.0 × ULN)1a (0.3)5c (0.9)18e (0.6)8h (0.7)CPK, U/LGr 3 (>5.0–10.0 × ULN)2a (0.6)3c (0.5)65e (2.0)36i (3.0)Gr 4 (>10.0 × ULN)0a (0)3c (0.5)27e (0.8)15i (1.3)Creatinine, μmol/LGr 3 (>3.0–6.0 × ULN)0a (0)1c (0.2)3e (<0.1)2j (0.2)Gr 4 (>6.0 × ULN)0a (0)4c (0.7)8e (0.3)1j (<0.1)an=312. bn=576. cn=577. dn=3201. en=3199. fn=1193. gn=1192. hn=1195. in=1196. jn=1197ULN, upper limit of normalConclusion:This long-term analysis of UPA-treated pts with RA showed dose-dependent relationships for several laboratory abnormalities.

Abstract
Background:Pneumococcal vaccination is recommended in patients with RA who are receiving conventional synthetic/biologic DMARDs.1 Upadacitinib (UPA) is an oral Janus kinase (JAK) inhibitor engineered to have a greater selectivity for JAK1 versus JAK2, JAK3, and tyrosine kinase 2, and is approved for the treatment of RA.Objectives:The aim of this analysis was to assess the impact of long-term treatment with UPA + background MTX on immunologic responses to Prevnar 13® (Pneumococcal 13-valent Conjugate Vaccine [Diphtheria CRM197 Protein]; PCV13) in patients with RA enrolled in the ongoing Phase 2 open-label extension study BALANCE-EXTEND.Methods:Patients from BALANCE-EXTEND receiving PCV13 vaccination were required to be on UPA 15 mg once daily (QD) or 30 mg QD and background MTX for ≥4 weeks prior to, and after, PCV13 vaccination; MTX was not interrupted prior to vaccination. Vaccination antibody titers were collected pre-vaccination (Week 0) and post-vaccination (Weeks 4 and 12). The primary variable was the proportion of patients with satisfactory humoral response to PCV13 (≥2-fold increase in antibody concentration from pre-vaccination [Week 0] in ≥6/12 pneumococcal antigens [1, 3, 4, 5, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F]) at 4 weeks post-vaccination.Results:Of 111 patients (UPA 15 mg, n=87; UPA 30 mg, n=24), 86% were female, most (98%) were white, and mean (standard deviation) age was 58.4 (12.0) years. Prior to vaccination, patients had a median (range) duration of RA of 9.3 (3.4–35.0) years and had been receiving UPA for a median (range) of 3.9 (3.0–4.9) years. All but 3 patients were taking concomitant MTX, and 44.1% were taking a CS (median daily dose, 5.0 mg). All 111 patients received PCV13, none discontinued UPA during the first 4 weeks, and blood samples were available from 83/23 and 79/22 patients in the UPA 15/30 mg groups at Weeks 4 and 12, respectively. At 4 weeks, satisfactory humoral response to PCV13 occurred in 67.5% (95% confidence interval [CI]: 57.4–77.5) and 56.5% (95% CI: 36.3–76.8) of patients receiving UPA 15 and 30 mg, respectively. At 12 weeks, satisfactory humoral response to PCV13 occurred in 64.6% (95% CI: 54.0–75.1) and 54.5% (95% CI: 33.7–75.4) of patients receiving UPA 15 and 30 mg, respectively (Figure 1). There was no clear difference in response between patients receiving and not receiving concomitant CS. Within 30 days post-vaccination, 2 adverse events (AEs) were considered as possibly related to UPA (1 case of diverticulitis, UPA 15 mg; 1 case of anemia, UPA 30 mg) and no serious AEs were reported (Table 1). Two patients experienced pyrexia and 1 subject each experienced vaccination-site pain and headache within 1 day post-vaccination (all in UPA 15 mg group).Table 1.Safety through 30 days post-PVC13 vaccination in UPA-treated patientsEvent, n (%)UPA 15 mg QD (n=87)UPA 30 mg QD (n=24)Any AE15 (17.2)3 (12.5)Serious AE00AE leading to discontinuation of study drug00AE with reasonable possibility of being related to UPAa1 (1.1)b1 (4.2)cDeath00aAs assessed by the investigator. bDiverticulitis. cAnemia.AE, adverse event; PVC13, Pneumococcal 13-valent Conjugate Vaccine [Diphtheria CRM197 Protein]; QD, once daily; UPA, upadacitinib.Conclusion:Satisfactory humoral response to PCV13 at 4 weeks occurred in ~two-thirds of patients with RA receiving long-term treatment with UPA 15 mg QD + background MTX. This is broadly consistent with pneumococcal vaccine humoral responses observed in patients with RA treated with other JAK inhibitors, biologics, or placebo.2–4References:[1]Singh JA, et al.

Abstract
Background:Upadacitinib (UPA), an oral Janus kinase inhibitor, demonstrated significant improvements in signs, symptoms, and structural inhibition as monotherapy (mono) vs methotrexate (MTX) in MTX-naïve patients (pts) with rheumatoid arthritis (RA) through 48 weeks (wks).1Objectives:To report the efficacy and safety of UPA vs MTX mono up to 156 wks in pts with RA from the ongoing long-term extension (LTE) of the SELECT-EARLY trial.Methods:During the 48-wk double-blind study period, pts were randomized to UPA 15 or 30 mg once daily (QD) or MTX (titrated to 20 mg/wk by Wk 8). At Wk 26, pts who did not achieve Clinical Disease Activity Index (CDAI) remission (≤2.8) and had <20% improvement from baseline in tender or swollen joint count received blinded rescue therapy (addition of MTX for UPA groups and UPA 15 or 30 mg for MTX group). In the LTE, pts received open-label treatment once the last pt reached Wk 48. Efficacy assessments up to Wk 156 were summarized by randomized group and included American College of Rheumatology (ACR) responses, remission and low disease activity (LDA) measures, and change in modified Total Sharp Score (mTSS; up to 96 wks). Treatment-emergent adverse events (AEs) per 100 pt-years (PY) for pts on continuous mono were summarized through 156 wks. Non-responder imputation was used for binary endpoints for missing data and when pts received rescue therapy or prematurely discontinued the study drug.Results:Of 945 pts randomized and treated, 775 entered the LTE on study drug (including 57 rescued pts; MTX, 33; UPA 15 mg, 17; UPA 30 mg, 7). Overall, 161 (21%) pts discontinued during the LTE. At Wk 156, higher proportions of pts randomized to UPA achieved a 20/50/70% improvement in ACR response (ACR20/50/70), LDA, and remission vs MTX (Figure 1). Change from baseline in mTSS at Wk 96 favored UPA vs MTX (data not shown). Most AEs were numerically more frequent with UPA 30 mg. The overall rate of serious infection was numerically higher with UPA vs MTX (Table 1). Herpes zoster (HZ), neutropenia, non-melanoma skin cancer (NMSC), and creatine phosphokinase (CPK) elevation were more frequent with UPA vs MTX. Two active tuberculosis (TB) events were reported in each UPA arm; 3 adjudicated gastrointestinal (GI) perforation events were observed in the UPA 30 mg arm. Adjudicated major adverse cardiovascular events (MACEs) or venous thromboembolic events (VTEs) were comparable across treatment arms.Conclusion:UPA monotherapy showed sustained clinically meaningful responses including remission vs MTX through Wk 156 but higher rates of several AEs, including HZ, neutropenia, and CPK elevations; no new safety risks were observed compared with previous results.1,2References:[1]van Vollenhoven R, et al.

Abstract
Background:In the SELECT-COMPARE study, the Janus kinase inhibitor, upadacitinib (UPA), demonstrated significant improvements in the signs and symptoms of rheumatoid arthritis (RA) when administered at 15 mg once daily (QD) on background methotrexate (MTX) compared with adalimumab (ADA) plus MTX at Week 12 that were maintained through 72 weeks in patients with prior inadequate response to MTX.1Objectives:To assess the long-term safety and efficacy of UPA vs ADA over 3 years in the ongoing long-term extension (LTE).Methods:Patients receiving background MTX were randomized 2:2:1 to UPA 15 mg QD, placebo (PBO), or ADA 40 mg every other week. Between Weeks 14-26, rescue was mandated for either lack of response (<20% improvement in tender or swollen joint counts: Weeks 14, 18, 22) or failure to achieve a targeted disease outcome (CDAI low disease activity: Week 26). Patients who completed the 48-week double-blind period could enter an LTE for up to 10 years total. This analysis describes patients through 3 years of treatment. Treatment-emergent adverse events (TEAEs) per 100 patient years (PY), including events of special interest (AESI), were summarized up to 3 years based on exposure to UPA and to ADA. Efficacy was analyzed by original randomized groups. Patients who were rescued or prematurely discontinued study drug were categorized as non-responders for visits after rescue or discontinuation. Descriptive analyses were performed without formal statistical comparisons.Results:In total, 651, 651, and 327 patients were randomized at baseline to receive UPA, PBO, and ADA, respectively. Between Weeks 14-26, 252 (39%) patients were rescued from UPA to ADA, 159 (49%) were rescued from ADA to UPA, and all PBO patients were switched to UPA by Week 26.1 A higher proportion of patients randomized to UPA completed 3 years without rescue compared to those randomized to ADA (47% vs 36%, respectively). UPA was generally well-tolerated as assessed by the rates of TEAEs, including serious AEs, AEs leading to discontinuation of study drug, and AESIs, including serious and opportunistic infections, malignancies, adjudicated major adverse cardiac events or venous thromboembolism; Figure 1). Consistent with previous analyses, the event rates of AESIs were generally comparable between the UPA and ADA groups, while herpes zoster, lymphopenia, hepatic disorder, and CPK elevation were reported at higher rates with UPA. Consistent with earlier time points, greater proportions of patients randomized to UPA achieved low disease activity and remission at 3 years based on CDAI, as well as DAS28(CRP) ≤3.2 or <2.6, compared with patients randomized to ADA (Table 1).Conclusion:The safety profile of UPA was consistent with the results reported previously and with the integrated Phase 3 safety analysis.1,2 Higher levels of clinical response continued to be observed with UPA vs ADA through 3 years of treatment.References:[1]Fleischmann R, et al.

Abstract
Dermatofibrosarcoma protuberans (DFSP) is a rare, slow-growing, spindle cell neoplasm with low to intermediate grade malignant potential, commonly found in young and middle-aged adults, more in males than females. DFSP mostly originates in the dermis; rarely, it may be located in the deeper tissues without dermal involvement. Typically, DFSP appears as a multinodular mass, which then spreads into the subcutaneous tissues and muscle; it rarely dedifferentiates to high-grade fibrosarcoma, and more rarely, it may metastasise. We describe magnetic resonance imaging (MRI) features in three female patients with histologically proven DFSP and review the literature.

Abstract
Funding Acknowledgements Type of funding sources: None. Introduction Decompensation of heart failure leading (HF) to hospitalisation is the single most important drain on healthcare resources when managing patients with left ventricular systolic dysfunction. Cardiac resynchronisation therapy with/without defibrillators (CRT-P/D) decreases hospitalisation due to HF and improves survival while implantable cardiac defibrillators (ICD"s) have a favourable effect on the former. Proprietary software algorithms embedded in these complex devices give an early warning to clinicians when decompensation of HF is imminent allowing preventative action to be undertaken. HeartLogic (HL) is one such new algorithm in Boston Scientific CRT-D/ICD devices using multiple sensors to track 5 physiological parameters, combining them into one composite Index, with an Alert being triggered if the Index is >16. The COVID-19 pandemic, due to multiple reasons, resulted in a significant decrease in availability of routine HF services in the United Kingdom, especially during the initial lockdown period from 23rd March to 1st July 2020. Aim To assess the impact of the COVID-19 pandemic, using HL, in patients with HF and complex devices. Materials and Methods Retrospective analysis of patients in a tertiary care cardiac centre in whom the HL software had been activated in March/April 2019 (n = 49) and comparison of those with (Group A n = 21) and without (Group B n = 28) an Alert (HLA) during the COVID-19 pandemic. Results (Table): Whole cohort n = 49. Age: 72 ± 12 years, Median: 75, Range: 36-95. 36/49 (73.5%) males. Type of device implanted: Resonate X4 CRT-D: 28/49 (57.1%); Momentum CRT-D: 8/49 (16.3%); Resonate ICD: 13/49 (26.5%). Ischaemic aetiology of HF: 35/49 (71.4%), Total duration of HL monitoring: 632 ± 7 days (median: 632; range: 626-672). There was no difference in the age, gender, and type of device implanted between Group A and Group B. Over nearly ∼1 year of monitoring in each of the groups, Group A had more unstable HF with 10/21 (47.6%) having their first HLA during the pandemic. Multiple HLA"s, longer period in HLA and those with ischaemic aetiology of HF were higher in Group A. 17/40 (42.5%) HLA"s in Group A were within the first lockdown period (March - July). 24/28 (85.7%) patients in Group B had no HLA"s either before or during the pandemic. There was no difference in the HLA score between Groups A and B. Conclusion In this limited group of patients with a medium term follow-up, using the HeartLogic software, patients with ischaemic aetiology of HF and those with more HLA"s prior to the pandemic did worse than those who no HLA"s. First HLA"s, multiple alerts and longer duration of alerts in this group of patients suggests a lack of access to adequate HF services during the pandemic. It has implications with regard to how HF services are configured in future whenever resources are constrained.

Abstract
Food handlers plays a primary role in the transmission of pathogenically important protozoans and helminth parasites. This study was aimed to evaluate the prevalence of intestinal pathogenic protozoans and helminth parasites among food handlers in and around University of Malakand, Lower Dir, Pakistan. Stool samples were collected from 642 food handlers (all of male) in a cross-sectional study from January to November, 2017. Wet Mount Techniques and concentration methods by using salt and formol-ether solutions. Three hundred and eighty four cases (59.8%) were found infected with one more parasites. Most of the individuals were found infected with helminth (47.6%) as compared to intestinal protozoans (0.93%). Seventy two cases (11.2%) of the cases presented mixed infection with both intestinal protozoan and helminth parasites. The order of prevalence for intestinal helminth was Ancylostoma duodenale (n = 258, 40.1%), followed by Taeniasa ginata (n=96, 14.9%) Ascaris lumbricoides (n = 54, 8.40%) and Trichuris trichura (n=30, 4.60%). For intestinal protozoa, Entamoeba histolytica/dispar (n = 36, 5.64%) was the only protozoan detected. Mono-parasitism was higher than poly-parasitism. Family size income and education level were the factors significantly (P<0.05) associated in the parasites prevalence. Current research showed that IPIs are primarily the foodborne pathogens still an important public health problem in Pakistan. Effective control programs on parasitic diseases transfer and their associated factors are recommended.

Abstract
Illnesses caused by human pinworm remains a pediatric health problem in developing nations including Pakistan. This study aimed to investigate the prevalence of Enterobius vermicularis in school children of four districts in Malakand region, Pakistan. Four hundred faecal specimens were screened from May 2014 to July 2017 using normal saline and Lugol Iodine solution. Twenty three (5.75%) individuals were found infected with E. vermicularis. Five children (1.25%) were infected with only E. vermicularis and eighteen (4.5%) were mixed with other helminths. E. vermicularis 23 (5.75%), hookworm 11 (2.75%), Ascaris lumbricoides 5 (1.25%), Taenia saginata 2 (0.5%) and Trichuris trichuira 4 (1%) were detected. Age wise 5-8 years were more parasitized followed by 13-15 and 9-12 years of age (0.0296, P<0.05). Male children were highly (0.06700, P<0.05) infected than female. Children in Malakand district were found more infected followed by Dir Upper, similar infection rate was noted in children of districts Lower Dir and Swat (0.0192, P<0.05). Children in primary level were highly (0.0013, P<0.05) infected than those of middle and high levels. Enterobiosis is still the most common parasitic diseases in children. Studies on enterobiosis should be conducted time by time to recognize the hazardous of such parasitic infection in remote areas of the country.

Abstract
Introduction Coronavirus disease (COVID-19) is an acute severe respiratory distress syndrome which resulted in an unprecedented impact on NHS service provision. We aimed to assess the impact of COVID-19 on general surgical services in a district general hospital. Method Electronic health care record data was retrospectively collected from 6th of April to 6th of May for both 2019 and 2020. Results Despite fewer referrals and admissions in 2020 (133 vs 177 admissions in 2019), there were more failed discharges (29 vs 17 in 2019) and higher associated costs. Higher numbers of biliary related pathologies and pancreatitis (50 in 2020 vs 25 in 2019), and fewer complaints of non-specific abdominal pain (10 in 2020 vs 22 in 2019) were observed. The use of outpatient investigations decreased by approximately 40% in 2020; however, utilisation of inpatient investigations was comparable. Conclusions Better utilisation of outpatient investigations and virtual clinic services may surmount pressures from further peaks of COVID-19. The increase in biliary related cases and pancreatitis may be consequent upon lifestyle changes during lockdown. This merits further investigation and if appropriate, public health intervention. In the absence of an efficacious vaccine, further research would be essential to streamline general surgical services based on clinical risk stratification.

Abstract
Introduction Higher number of cycling injuries were observed during the COVID-19 period in the United Kingdom at our institution. Many were serious injuries requiring hospitalisation and some requiring surgery. We investigated whether the lockdown led to a legitimate increase in incidence of cycling related injuries, resulting in a higher number of aerosol generating procedures (AGPs). This would assess whether the guidance on exercise during lockdown was appropriate, shaping future regulation in the case of cyclical lockdowns. Method Records were screened retrospectively for cycling related injuries between April 1st and May 12th (lockdown) 2020 and for same period in 2019 as a control group. Injury severity, distribution and number of surgical procedures resulting from these were assessed. Results The proportion of injuries due to cycling rose threefold (n = 55) during the COVID-19 lockdown. Injuries included fractures, soft tissue injuries and mixed injuries. An increase in the number of operative procedures (n = 13) and AGPs was also noted. Conclusions Vague guidance and allowance of one form of outdoor exercise per day may have unintentionally contributed to rise in cycling injuries as many took to cycling for recreation. To make the guidance appropriate, usual forms of exercise should be encouraged, risk taking behaviours discouraged and safe cycling practices endorsed.

Abstract
Non-Hodgkin's lymphoma (NHL) encompasses over 40 different haematological malignancies, including low and high-grade neoplasms, such as follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL) respectively. A key clinical issue in the context of NHL is delayed and inaccurate diagnosis, which contributes adversely to patient morbidity and mortality. This article will address relevant imaging aspects, with particular reference to advancements in NHL imaging, including computed tomography (CT), integrated positron-emission tomography (PET)-CT, and magnetic resonance imaging (MRI). We provide multiparametric (anato-functional) imaging display items, including histological correlation. We will also introduce our original concept of "Specialist Integrated Haematological Malignancy Imaging Reporting" (SIHMIR), a paradigm shift in lymphoma radiology.
