Guidance for the gastrointestinal evaluation and management of iron deficiency in Sub-Saharan Africa. S Afr Med J 2024; 114:e711. [PMID: 38525666 DOI: 10.7196/samj.2024.v114i1b.711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Indexed: 03/26/2024] Open
Abstract
BACKGROUND Over 30% of the world's population is anaemic, with a significant proportion of these being iron deficient. As iron deficiency (ID) anaemia in men and post-menopausal women is mostly caused by gastrointestinal blood loss or malabsorption, the initial evaluation of a patient with ID anaemia involves referral to a gastroenterologist. The current drive towards patient blood management in sub-Saharan Africa (SSA)prescribes that we regulate not only the use of blood transfusion but also the management of patients in whom the cause of iron loss or inadequate iron absorption is sought. Recommendations have been developed to: (i) aid clinicians in the evaluation of suspected gastrointestinal iron loss and iron malabsorption, and often a combination of these; (ii) improve clinical outcomes for patients with gastrointestinal causes of ID; (iii) provide current, evidence-based, context-specific recommendations for use in the management of ID; and (iv) conserve resources by ensuring rational utilisation of blood and blood products. METHOD Development of the guidance document was facilitated by the Gastroenterology Foundation of Sub-Saharan Africa and the South African Gastroenterology Society. The consensus recommendations are based on a rigorous process involving 21 experts in gastroenterology and haematology in SSA. Following discussion of the scope and purpose of the guidance document among the experts, an initial review of the literature and existing guidelines was undertaken. Thereafter, draft recommendation statements were produced to fulfil the outlined purpose of the guidance document. These were reviewed in a round-table discussion and were subjected to two rounds of anonymised consensus voting by the full committee in an electronic Delphi exercise during 2022 using the online platform, Research Electronic Data Capture. Recommendations were modified by considering feedback from the previous round, and those reaching a consensus of over 80% were incorporated into the final document. Finally, 44 statements in the document were read and approved by all members of the working group. CONCLUSION The recommendations incorporate six areas, namely: general recommendations and practice, Helicobacter pylori, coeliac disease, suspected small bowel bleeding, inflammatory bowel disease, and preoperative care. Implementation of the recommendations is aimed at various levels from individual practitioners to healthcare institutions, departments and regional, district, provincial and national platforms. It is intended that the recommendations spur the development of centre-specific guidelines and that they are integrated with the relevant patient blood management protocols. Integration of the recommendations is intended to promote optimal evaluation and management of patients with ID, regardless of the presence of anaemia.

Report of three patients with extensive neurocysticercosis in rural southern Tanzania: neurological, serological and neuroradiological findings. J Med Case Rep 2023; 17:311. [PMID: 37408061 DOI: 10.1186/s13256-023-03974-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Accepted: 05/05/2023] [Indexed: 07/07/2023] Open
Abstract
BACKGROUND Neurocysticercosis (NCC) is common in eastern Africa, but disease presentation varies considerably. Most patients have single or few NCC-typical lesions in their brain but some present with a large number of lesions. We present three patients with positive antibody-based serology for Taenia solium cysticercosis screened at the Vwawa district hospital, Mbozi district, southern Tanzania, in whom extensive NCC was confirmed by neuroimaging. CASE PRESENTATIONS Patient 1 was a 55-year-old female from the tribe Malila smallholder farmer who has had four generalized tonic-clonic epileptic seizures over a period of 11 years and one episode of transient left hemiparesis one year before seizure onset. The patient also reported monthly to weekly episodes of severe, progressive, unilateral headache. The computed tomography (CT) scan of the brain showed 25 NCC lesions of which 15 were in the vesicular stage. Patient 2 was a 30-year-old male from tribe Nyha mechanic who reported monthly episodes of moderate to severe, progressive, bilateral headache, but no epileptic seizures. The CT scan showed 63 NCC lesions of which 50 were in the vesicular stage. Patient 3 was a 54-year-old female from the tribe Malila smallholder farmer who suffered from frequent generalized tonic-clonic epileptic seizures with potential signs of focal seizure onset. She also reported weekly to daily episodes of severe, progressive, unilateral headache. The CT scan showed 29 NCC lesions of which 28 were in the vesicular stage. CONCLUSIONS Clinical presentation of NCC with multiple brain lesions varies considerably ranging from few epileptic seizures and severe headache to severe epilepsy with frequent epileptic seizures. Individuals with neurological signs/symptoms that may be due to NCC, based for example on epidemiological criteria or serological evidence of cysticercosis, are recommended to undergo neuroimaging before anthelminthic treatment is considered.

Abstract
Abstract
Background
Patients with multivessel disease (MVD) are at increased risk of recurrent cardiovascular (CV) events in the early period after acute myocardial infarction (AMI) compared to patients without MVD, possibly due to increased atherosclerotic burden. Moreover, many have additional risk factors such as older age, peripheral artery disease (PAD), prior AMI or diabetes that could further increase risk of recurrent events. Real-world evidence regarding the impact of additional CV risk factors on outcomes in patients with MVD remains sparse.
Purpose
To assess clinical outcomes in the early period after AMI in a UK cohort of patients with MVD and additional risk factors.
Methods
A retrospective analysis (January 1, 2008–December 31, 2018, inclusive) was conducted using the Clinical Practice Research Datalink database linked to Hospital Episode Statistics and Office of National Statistics databases to identify patients with a confirmed diagnosis of MVD within the study period and at least one non-fatal myocardial infarction (MI) diagnosis code on or after their first recorded MVD diagnosis. The effect of diabetes on clinical outcomes was assessed by comparing patients diagnosed with diabetes on or prior to their index AMI with those with no concurrent diabetes diagnosis (MVD+DM and MVD-DM cohorts, respectively). Clinical outcomes were also assessed in AMI patients without diabetes but with at least two additional risk factors including: age >65 years, PAD diagnosis or prior MI diagnosis (MVD2RF+ cohort), and those with a single or none of the aforementioned risk factors (MVD2RF- cohort). Major adverse CV events (MACE) was defined as a composite of non-fatal AMI, non-fatal stroke or CV death.
Results
Of the 78,128 patients with MVD identified, 19,768 and 52,197 were eligible for inclusion in the MVD+DM and MVD-DM cohorts respectively. Occurrence of MACE was similar between the MVD+DM and MVD-DM cohorts at both 90 days (15% vs. 14%) and 1 year (19% vs. 17%) post-AMI; however, all-cause and CV mortality were significantly higher in the MVD+DM cohort over the study period (p<0.001). In the subset of patients without diabetes, 7,531 and 44,666 patients met the criteria for the MVD2RF+ and MVD2RF- cohorts, respectively. A substantially higher proportion of patients in the MVD2RF+ cohort experienced a MACE within 90 days or 1 year post-MI compared with the MVD2RF- cohort (90 days: 45% vs. 9%; 1 year: 56% vs. 11%), with non-fatal MI accounting for the majority of recurrent events. Kaplan-Meier survival analysis revealed that both all-cause and CV mortality were significantly higher in the MVD2RF+ than the MVD2RF- cohort (p<0.001).
Conclusions
Having multiple risk factors including older age, PAD and a history of AMI substantially increases the risk of recurrent events in patients with MVD, particularly in the early period after AMI. Strategies to reduce the systemic atherosclerotic burden and risk of recurrent events in these patients are needed.

Measurement properties of the WHO Disability Assessment Schedule 2.0 for evaluating functional status after inpatient surgery. Br J Surg 2022; 109:968-976. [PMID: 35929065 DOI: 10.1093/bjs/znac263] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Revised: 05/17/2022] [Accepted: 07/08/2022] [Indexed: 11/12/2022]
Abstract
BACKGROUND Expert recommendations propose the WHO Disability Assessment Schedule (WHODAS) 2.0 as a core outcome measure in surgical studies, yet data on its long-term measurement properties remain limited. These were evaluated in a secondary analysis of the Measurement of Exercise Tolerance before Surgery (METS) prospective cohort. METHODS Participants were adults (40 years of age or older) who underwent inpatient non-cardiac surgery. The 12-item WHODAS and EQ-5DTM-3L questionnaires were administered preoperatively (in person) and 1 year postoperatively (by telephone). Responsiveness was characterized using standardized response means (SRMs) and correlation coefficients between change scores. Construct validity was evaluated using correlation coefficients between 1-year scores and comparisons of WHODAS scores across clinically relevant subgroups. RESULTS The analysis included 546 patients. There was moderate correlation between changes in WHODAS and various EQ-5DTM subscales. The strongest correlation was between changes in WHODAS and changes in the functional domains of the EQ-5D-3L-for example, mobility (Spearman's rho 0.40, 95 per cent confidence interval [c.i.] 0.32 to 0.48) and usual activities (rho 0.45, 95 per cent c.i. 0.30 to 0.52). When compared across quartiles of EQ-5D index change, median WHODAS scores followed expected patterns of change. In subgroups with expected functional status changes, the WHODAS SRMs ranged from 'small' to 'large' in the expected directions of change. At 1 year, the WHODAS demonstrated convergence with the EQ-5D-3L functional domains, and good discrimination between patients with expected differences in functional status. CONCLUSION The WHODAS questionnaire has construct validity and responsiveness as a measure of functional status at 1 year after major surgery.

Abstract
Abstract
Background
Despite numerous interventions that have improved outcomes in acute myocardial infarction (AMI) patients, the first 90 days after AMI remains a high-risk period for recurrent events. Due to higher disease burden and suboptimal outcomes, it is crucial to characterize the clinical burden upon patients with multivessel disease (MVD) and various comorbidities.
Purpose
To describe the post-AMI clinical burden of major adverse cardiovascular events (MACE) in patients with MVD at 30, 90, and 365 days.
Methods
This was a retrospective cohort study (1st January, 2008 to 31st December, 2018) using data from a longitudinal, representative UK population health dataset comprising primary care data from the Clinical Practice Research Datalink (CPRD). This was linked to data from the Hospital Episode Statistics (HES) and Office of National Statistics (ONS) databases to identify patients with a confirmed diagnosis code of MVD. A MACE was defined as any one of non-fatal MI, non-fatal stroke, or cardiovascular death. The prevalence of MACE among post-AMI patients with MVD and the effect of concurrent risk factors was quantified.
Results
403,631 patients with MVD were identified (21.69% of the total study population), nearly one-fifth of whom (n=78,128; 19.35%) experienced an AMI after their first recorded diagnosis of MVD (MVD+). The mean and median age of MVD+ patients was 66 years, and the majority (72.9%) were male. Almost half (48.9%) had a Charlson co-morbidity score of at least 1, and 99.8% had an index of multiple deprivation recorded, distributed evenly across the quintiles. At least one of the composite MACE occurred in 9,533 (12.2%), 11,694 (14.9%), and 15,188 (19.4%) MVD+ patients within 30, 90, and 365 days, respectively. In MVD+ patients with 2 or more additional risk factors (peripheral artery disease [PAD], age >65, prior AMI; w/out comorbid diabetes; n=7,531), the proportion of MACE within 90 days was substantially higher (42.7%). Non-fatal MI was the most common MACE episode in MVD+ patients, occurring in 7,696, (9.8%), 8,924 (11.4%), and 10,673 (13.7%) MVD+ patients at 30, 90, and 365 days, respectively. Within 90 days of AMI, 39.1% of MVD+ patients with 2 or more risk factors experienced non-fatal MI.
Conclusions
MVD patients have a considerable clinically relevant burden of MACE following AMI. The majority of 1-year recurrent events occurred within 90 days of MACE, with 90-day risk almost 3-fold higher in patients with two additional risk factors. For patients with MVD and other risk factors, opportunities remain for treatments that may reduce the risk of recurrent events in the early period following AMI.

Abstract
Abstract
Background
There is emerging evidence that particularly high rates of major adverse cardiovascular events (MACE) occur in the 90-day period after acute myocardial infarction (AMI). Post-AMI MACE are associated with additional resource utilization and economic burden for healthcare systems, with multivessel disease (MVD) conferring a 3- to 4-fold increase in risk of recurrent MACE in the first year post AMI vs. single vessel disease. Thus, characterizing the prevalence and outcomes of patients with MVD and various comorbidities is crucial to predict and mitigate clinical risk and associated costs.
Purpose
To describe post-AMI readmissions and economic burden in MVD patients at 30, 90, and 365 days.
Methods
This was a retrospective cohort study (1st January, 2008 to 31st December, 2018). Patients with MVD were identified by a confirmed diagnosis code from a longitudinal, representative UK population health dataset comprising primary care data from the Clinical Practice Research Datalink (CPRD), which was linked to secondary care data from the Hospital Episode Statistics (HES) and Office of National Statistics (ONS) databases. Patients who experienced at least one AMI after their first recorded MVD diagnosis were defined as MVD+. A MACE was defined as any one of non-fatal MI, non-fatal stroke, or cardiovascular death. Readmissions were defined as non-elective admissions with a MACE outcome diagnosis occurring up to 28 days from a previous admission with the same treatment speciality.
Results
The study population included 78,128 MVD+ patients (4.2% of the total patient population). In the MVD+ cohort, 3,753 (4.8%) patients were readmitted with at least one MACE event or other non-elective admission within the cardiovascular specialty: 2,394 (63.8%), 2,562 (68.3%), and 2,830 (75.4%) readmissions occurred within 30, 90, and 365 days, respectively. The mean length of hospital stay per patient, per readmission for MACE within 30, 90, and 365 days was 7.22, 7.46, and 7.74 days, respectively. The mean cost per MACE admission within 90 days of index AMI was £3,926.52. Non-fatal MI was the most common reason for readmission at all timepoints. Percutaneous transluminal balloon angioplasty and saphenous vein graft procedures (coronary artery bypass graft, CABG) were among the most common cardiac procedures in MVD+ patients, at 70,276 (22.7%) and 15,418 (5.0%), respectively.
Conclusions
In patients with MVD who suffer an AMI, there is high resource utilization and cost, particularly in the first 90-days post AMI; therefore, the 90-day post-AMI period represents significant economic costs to healthcare systems.

Adherence to guideline-recommended care following acute myocardial infarction: impact on clinical outcomes at 90 days and 1 year. Eur Heart J 2021.

Abstract
Abstract
Background
Guideline-recommended care is effective for secondary prevention following acute myocardial infarction (AMI); however, most pharmacotherapies take time to become efficacious and not all patients comply with treatment. It is well established that the risk of recurrent cardiovascular (CV) events is high following an AMI; however, the clinical burden of recurrent CV events among guideline-treated patients, specifically in the 90-day period post-AMI, has been relatively unexplored.
Purpose
To evaluate adherence to guideline-recommended care and determine how it impacts clinical outcomes at 90 days and 1 year post-discharge in a U.S. population.
Methods
A retrospective analysis was conducted using the IBM Health Marketscan Commercial Claims and Encounters database (July 1, 2013–June 1, 2016). In U.S. individuals with a primary diagnosis of AMI, adherence to evidence-based care was assessed in terms of claims for guideline-recommended interventions: completed physician follow-up visit within 30 days of discharge, participation in cardiac rehabilitation, and adherent (PDC ≥0.8) to beta-blocker, antiplatelet, statin, and ACE inhibitor/ARB drug classes in the year following discharge. Rates of rehospitalisation (all-cause and cardiac) and recurrent AMI events within 90 days and 1 year post-AMI were evaluated.
Results
Of the 21,977 patients included in the analysis, the majority (80.9%) visited a physician within 30 days of discharge, but few (15.4%) entered cardiac rehabilitation or were adherent to all guideline-recommended drug classes (17.1%). Even in patients fully compliant with guideline-recommended care (3.1% of the total population), event rates were high in the first year post-MI (recurrent AMI: 1.6%; cardiac rehospitalisation: 8.9%; all-cause hospitalisation 13.3%) with a large proportion of the events occurring in the first 90 days: 75%, 58.4%, and 51.1% respectively. Adherence to all drug classes significantly reduced the risk of all-cause and cardiac rehospitalisation but did not reduce the risk of recurrent AMI events (OR=1.03 [95% CI 0.73–1.46] at 90 days and OR=0.80 [95% CI 0.60–1.07] at 1 year) when compared to patients not receiving guideline-recommended pharmacotherapy.
Conclusions
Even among patients receiving guideline-recommended treatment following discharge, the risk of recurrent events remained high at both 90 days and 1 year in patients following an AMI. Novel approaches to reducing the risk of early recurrent AMI, in particular, are needed.

Longitudinal course and phenotypes of health-related quality of life in adults with atopic dermatitis. Clin Exp Dermatol 2021; 47:359-372. [PMID: 34623642 DOI: 10.1111/ced.14948] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 08/27/2021] [Accepted: 09/23/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND The real-world course of health-related quality of life (HRQoL) in atopic dermatitis (AD) is not well established. AIM To examine predictors, longitudinal course and phenotypes of HRQoL in adult patients with AD. METHODS This was a prospective dermatology-practice based study of 955 patients with AD (age 18-97 years). Patients were assessed at baseline and approximately 6, 12, 18 and 24 months. HRQoL was assessed using the 10-item short-form Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health (PGH). AD severity and impact was assessed by patient-reported global AD severity, Patient-Oriented Eczema Measure (POEM), Eczema Area and Severity Index (EASI), Objective SCORing Atopic Dermatitis (O-SCORAD), Investigator's Global Assessment (IGA), Numerical Rating Scale (NRS) average and worst itch, PROMIS sleep-related impairment (SRI), and nine-item Patient Health Questionnaire (PHQ)-9. Repeated-measures regression models were constructed to examine itch over time. RESULTS In multivariable linear regression models controlling for age, race/ethnicity, history of asthma, hay fever and food allergy, baseline PGH-physical (PGH-P4) T scores were inversely associated with patient-reported global AD severity, POEM, EASI, objective SCORAD, IGA, NRS average and worst itch, PROMIS SRI and PHQ-9, with stepwise decreases of physical health with worsening severity. PGH-mental health (PGH-M4) T scores were associated with all aforementioned severity measures aside from POEM. In multivariable repeated measures linear regression models, decreased PGH-P4 and PGH-M4 T scores and mapped five-dimension EuroQoL over time were associated with self-reported global AD severity, NRS worst and mean itch, POEM, PROMIS sleep disturbance and SRI, EASI, objective SCORAD, IGA and PHQ-9. Latent class analysis identified six classes of HRQoL, which were associated with measures of AD severity, nonwhite race, Hispanic ethnicity and having only public health insurance, but not age or sex. CONCLUSION Patients with AD have a heterogeneous longitudinal course and distinct patterns of HRQoL. Many patients had fluctuating HRQoL over time. Most patients with moderate to severe disease at baseline had persistent HRQoL impairment over time.

Psychometric validation and responder definition of the sleep disturbance numerical rating scale in moderate-to-severe atopic dermatitis. Br J Dermatol 2021; 186:285-294. [PMID: 34608623 PMCID: PMC9299666 DOI: 10.1111/bjd.20783] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/30/2021] [Indexed: 11/27/2022]
Abstract
Background Sleep disturbance (SD) is an important part of the burden of atopic dermatitis (AD), but patient‐reported outcomes that are easy to understand and interpret in the target population have been lacking. A daily, single‐item, self‐reported SD 11‐point numerical rating scale (NRS) was recently developed to assess SD for patients with moderate‐to‐severe AD, but its psychometric properties have not yet been described. Objectives To assess the psychometric properties of the SD NRS in patients with moderate‐to‐severe AD. Methods The psychometric properties of the SD NRS were assessed using data from a phase IIb clinical trial in 218 adults with moderate‐to‐severe AD. Results Test–retest reliability of the SD NRS was substantial to almost perfect (interclass correlation 0·66–1·00) in participants who had stable SD or stable pruritus scores over 1 week. Baseline correlations were moderate to large (r > 0·30) between SD NRS and pruritus or sleep loss scores, but were small (r = −0·11 to 0·17) between SD NRS and EQ‐5D‐3L index and visual analogue scores, Hospital Anxiety and Depression Scale, Scoring Atopic Dermatitis, and Investigator’s Global Assessment. The SD NRS could discriminate groups of participants in the expected direction according to different quality‐of‐life scores but not according to different clinician‐reported disease severity scores. SD NRS scores significantly decreased as sleep loss, itch and quality‐of‐life scores improved. Analysis of meaningful change suggested a 2–5‐point improvement as the initial range of responder definition in the SD NRS score. Conclusions The SD NRS is a reliable, valid and responsive measure of SD in adults with moderate‐to‐severe AD. Whatis already known about this topic? Sleep disturbance (SD) is a dynamic, multidimensional concept resulting in daytime fatigue and subsequent changes in physical and mental health that vary from day to day. SD is an important part of the burden of atopic dermatitis, but ways of effectively and reliably measuring it from the patient perspective have been lacking. A self‐reported, daily, 11‐point SD numerical rating scale (NRS) was recently developed for assessing SD in patients with moderate‐to‐severe atopic dermatitis, and its content validity was previously established.
Whatdoes this study add? The study showed that the SD NRS is reliable, valid and responsive and can measure day‐to‐day fluctuations in SD related to atopic dermatitis. The study also established an initial responder definition (i.e. meaningful interpatient change) for the SD NRS score.
Whatare the clinical implications of this work? The SD NRS is a brief, simple, easy‐to‐interpret and validated patient‐reported global measure for the daily assessment of SD related to atopic dermatitis. The SD NRS can be used in clinical trials and clinical practice to assess changes in sleep quality in patients with atopic dermatitis.

Clinical characteristics and disease burden in prurigo nodularis. Clin Exp Dermatol 2021; 46:1277-1284. [PMID: 33969517 DOI: 10.1111/ced.14722] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 04/17/2021] [Accepted: 05/04/2021] [Indexed: 12/25/2022]
Abstract
BACKGROUND Prurigo nodularis (PN) is a chronic inflammatory skin disease characterized by intense pruritus, but information on patient experience and impact on quality of life (QoL) remains understudied. AIM To characterize disease characteristics and QoL in a global sample of patients with PN. METHODS An anonymous survey was distributed via patient support groups for PN. RESULTS In total, 231 members responded to the survey. The majority of respondents reported itch localized both to nodules and to intervening skin (67.0%). Associated symptoms included prickling, pain, stinging and burning. The extensor lower legs (69% right, 67.3% left) and flexor forearms (66.1% right, 62% left) were the most common sites of itch. Participants reported frequent healthcare utilization, with 36.3% visiting a doctor ≥ 10 times in the past year. Physician-diagnosed anxiety (45.4%), depression (16.4%) and the atopic triad (18.7%) were commonly reported. Patients with PN had mean scores of 16.4, 11.6 and 16.8 on the Dermatology Life Quality Index, Pittsburgh Sleep Quality Index and 5-Dimensions Itch, respectively. CONCLUSIONS Severe pruritus with accompanying pain, stinging and burning is characteristic of PN, with the majority of patients experiencing itch in both nodular and interlesional skin. Patients further report decreased QoL scores and impaired sleep. Patient experiences should guide future management of PN.

Abstract
BACKGROUND Prurigo nodularis (PN) is associated with a variety of systemic comorbidities, including infectious diseases such as HIV and viral hepatitis. There are limited data on other infectious disease comorbidities in patients with PN. AIM To characterize infectious disease hospitalizations among patients with PN and the associated cost burden. METHODS We searched the 2016-2017 National Inpatient Sample, a cross-sectional sample of 20% of all US hospitalizations, for infectious disease hospitalizations among patients with PN. Associations of PN with infections and related costs were determined using multivariable logistic and linear regression, adjusting for age, race, sex and insurance type. RESULTS PN was associated with any infection overall (OR = 2.98, 95% CI 2.49-3.56), and with HIV, cutaneous, hepatobiliary, central nervous system, bacterial, viral and fungal/parasitic infections and for sepsis. Patients with PN had a higher mean cost of care (US$11 667 vs. US$8893, P < 0.001) and length of stay (5.5 vs. 4.2 days, P < 0.001) for any infection overall and for 7 of 13 other infections. Adjusting for age, race, sex and insurance coverage, PN was associated with higher cost (+30%, 95% CI +17 to +44%) and higher length of stay (+30%, 95% CI +18 to +44%) for any infection overall, and for several specific infections. These associations remained with alternate regression models adjusting for severity of illness. CONCLUSION There is a high infectious disease burden among patients with PN, corresponding to higher healthcare utilization and spending. Clinicians must be aware of these associations when treating these patients with immunomodulatory drugs.

Abstract
BACKGROUND Multiple strategies have been used to evaluate the minimal important change (MIC) of the Eczema Area and Severity Index (EASI) and Scoring Atopic Dermatitis (SCORAD). The meaningfulness of these MICs is not well established across all severities of atopic dermatitis (AD). OBJECTIVES To determine the MIC of percentage and absolute improvement of EASI and SCORAD scores in adults and children with AD. METHODS We performed a prospective dermatology practice-based study using questionnaires and evaluation by a dermatologist (n = 826). An anchor-based approach was used to determine thresholds for the percentage and absolute MICs of EASI, SCORAD and objective SCORAD (O-SCORAD) at follow-up from baseline. RESULTS One-grade improvements of Physician's Global Assessment (PGA) and validated Investigator Global Assessment scale for AD (vIGA-AD) were associated with 50%, 35% and 35% decreases of EASI, SCORAD and O-SCORAD, respectively. The thresholds for percentage MIC of EASI (Kruskal-Wallis test, P = 0·61), SCORAD (P = 0·07) and O-SCORAD (P = 0·09) were similar across baseline AD severities. One-grade improvements of PGA and vIGA-AD were associated with 14·0- and 14·9-point decreases of EASI, 19·9- and 14·9-point decreases of SCORAD, and 15·5- and 17·4-point decreases of O-SCORAD. The thresholds for the absolute MIC of EASI (P < 0·001), SCORAD (P < 0·001) and O-SCORAD (P < 0·001) significantly differed by baseline AD severity. Percentage and absolute MICs for EASI and SCORAD were associated with improvements of AD symptoms and quality of life. CONCLUSIONS EASI 50, SCORAD 35 and O-SCORAD 35 were meaningful percentage MICs regardless of baseline AD severity. The absolute MICs for EASI, SCORAD and O-SCORAD varied by baseline AD severity.

Abstract
BACKGROUND Multiple clinician-reported outcome measures exist for atopic dermatitis (AD) severity. However, there is no gold standard for use in clinical practice. OBJECTIVES To determine the measurement properties of the product of validated Investigator's Global Assessment for AD (vIGA) and body surface area (BSA) overall or divided into six categories (cBSA: 0%/0.1, <10%/10, <30%/30, <50%/50, <70%/70 and <90%/90-100%) and compare with other clinician-reported and patient-reported outcomes in adults and children with AD. METHODS We performed a prospective dermatology practice-based study using questionnaires and evaluation by a dermatologist (n = 653). RESULTS vIGA*BSA and vIGA*cBSA had good convergent validity with BSA (Spearman's ρ = 0.97 and 0.93), eczema area and severity index (ρ = 0.94 and 0.92), and objective SCORAD (ρ = 0.88 and 0.89); and weak-to-good convergent validity with Numeric Rating Scale average itch (ρ = 0.22 and 0.22) and worst itch (ρ = 0.27 and 0.28), Patient-Oriented Eczema Measure (ρ = 0.44 and 0.43), Dermatology Life Quality Index (ρ = 0.48 and 0.49), ItchyQOL (ρ = 0.45 and 0.46), PROMIS Sleep Disturbance (ρ = 0.46 and 0.37) and sleep-related impairment (ρ = 0.31 and 0.31) in adults and/or children; very good discriminant validity for physician-reported global AD severity; good responsiveness to change of severity of AD and itch; and good reliability (intraclass correlation coefficient [95% confidence interval]: 0.72 [0.60-0.81] and 0.74 [0.62-0.82]) with no floor or ceiling effects. Thresholds for interpretability bands and clinically important difference were established. CONCLUSIONS vIGA*BSA and vIGA*cBSA scores showed good convergent and discriminant validity, reliability, responsiveness and interpretability in adults and children with AD, and were feasible for use in clinical practice. vIGA*BSA and vIGA*cBSA had slightly lower convergent validity than EASI or objective SCORAD, but might be more efficient to collect and score.

Abstract
Background:Rheumatologic disorders and inflammatory bowel disease can affect women of childbearing potential. Golimumab (GLM) is approved for several rheumatologic indications and ulcerative colitis (UC).Objectives:To characterize pregnancy outcomes in patients treated with GLM, data obtained from maternal exposure to GLM are presented.Methods:This dataset includes individual patient cases reported to the manufacturer through 06 April 2019. Cases included in the analysis were medically confirmed cases of maternal exposures to GLM during pregnancy or within 3 months prior to conception, and a reported pregnancy outcome. Both prospectively reported (ie, pregnancy outcome not known when first reported) and retrospectively reported cases (ie, pregnancy outcome known when first reported) were included. Cases originated from various sources, including spontaneous reporting, clinical studies, and registries.Results:Two hundred eight pregnancy cases (131 rheumatologic indications; 43 UC; and 34 other) with 211 reported birth outcomes were identified. Of these 208 pregnancy cases, 119 were prospective and 89 were retrospective. Average maternal age was 31.9 years. Of the 119 prospectively reported pregnancy cases, 89 (74.8%) resulted in live births, 19 (16.0%) resulted in spontaneous abortion (of these, 42.1% (8/19) received GLM in combination with methotrexate [MTX]), 10 (8.4%) resulted in induced/elective abortion, and 1 (0.8%) resulted in ectopic pregnancy. Overall, 9 congenital anomalies were reported (2 prospective and 7 retrospective cases).For 183 of the 208 pregnancy cases with reported outcomes, the trimester of exposure to GLM was known. Among the 110 prospectively reported cases, 82 (74.5%) were exposed during trimester 0 or 1. Of these, 19 had concomitant exposure to MTX, with the following birth outcomes: 8 live births, 8 spontaneous abortions, 3 elective/induced abortions. Eighteen of the prospectively reported cases (16.4%) were exposed to GLM through trimesters 1-3 and all resulted in live births (none with congenital anomalies; 1 infant with exposure to GLM and MTX was born preterm).Conclusion:The rates of congenital malformations and spontaneous abortions were consistent with published background rates for the general population. Persistent exposure throughout pregnancy was rare. Limitations of this analysis include the lack of a direct comparison group, the variable amount of data available in the reports, and the possible bias towards reporting more negative outcomes in retrospective cases.Disclosure of Interests:Marijo Otero-Lobato Shareholder of: Johnson & Johnson, Employee of: Johnson & Johnson, Suzan Esslinger Shareholder of: Johnson & Johnson, Consultant of: Johnson & Johnson, Novartis, Eli Lilly and Sandoz, Employee of: Johnson & Johnson, Susan Gabriel Shareholder of: Johnson & Johnson, Employee of: Johnson & Johnson, Merck, GSK, Michael Clark Shareholder of: Johnson & Johnson, Employee of: Johnson & Johnson, Pamela Sheridan Shareholder of: Johnson & Johnson, Roche Pharmaceuticals, Employee of: Johnson & Johnson, Roche, Novartis, Bayer, Anja Geldhof Shareholder of: Johnson & Johnson, Employee of: Johnson & Johnson

Abstract
Marine food-reliant subsistence systems such as those in the African Middle Stone Age (MSA) were not thought to exist in Europe until the much later Mesolithic. Whether this apparent lag reflects taphonomic biases or behavioral distinctions between archaic and modern humans remains much debated. Figueira Brava cave, in the Arrábida range (Portugal), provides an exceptionally well preserved record of Neandertal coastal resource exploitation on a comparable scale to the MSA and dated to ~86 to 106 thousand years ago. The breadth of the subsistence base-pine nuts, marine invertebrates, fish, marine birds and mammals, tortoises, waterfowl, and hoofed game-exceeds that of regional early Holocene sites. Fisher-hunter-gatherer economies are not the preserve of anatomically modern people; by the Last Interglacial, they were in place across the Old World in the appropriate settings.

How does gatekeeper training improve suicide prevention for elderly people in nursing homes? A controlled study in 24 centres. Eur Psychiatry 2020; 37:56-62.

Abstract
AbstractBackgroundThe death rate due to suicide in elderly people is particularly high. As part of suicide selective prevention measures for at-risk populations, the WHO recommends training “gatekeepers”.MethodsIn order to assess the impact of gatekeeper training for members of staff, we carried out a controlled quasi-experimental study over the course of one year, comparing 12 nursing homes where at least 30% of the staff had undergone gatekeeper training with 12 nursing homes without trained staff. We collected data about the residents considered to be suicidal, their management further to being identified, as well as measures taken at nursing home level to prevent suicide.ResultsThe two nursing home groups did not present significantly different characteristics. In the nursing homes with trained staff, the staff were deemed to be better prepared to approach suicidal individuals. The detection of suicidal residents relied more on the whole staff and less on the psychologist alone when compared to nursing homes without trained staff. A significantly larger number of measures were taken to manage suicidal residents in the trained nursing homes. Suicidal residents were more frequently referred to the psychologist. Trained nursing homes put in place significantly more suicide prevention measures at an institutional level.ConclusionsHaving trained gatekeepers has an impact not only for the trained individuals but also for the whole institution where they work, both in terms of managing suicidal residents and routine suicide prevention measures.

Abstract
Background Quantification of burden of chronic spontaneous urticaria (CSU) vs. psoriasis (PsO) is limited. Objective To evaluate the burden associated with CSU vs. PsO of all severities (overall PsO), mild and moderate/severe PsO. Methods This retrospective cross‐sectional analysis compared data from adult patients with chronic urticaria (CU), used as a proxy for CSU, and PsO from the National Health and Wellness Survey in France, Germany, Italy, Spain and the United Kingdom. Outcomes included mental and physical component summary scores (MCS and PCS) calculated from the Short Form (SF)‐36v2 or SF‐12v2, SF‐6D health utility scores, self‐reported psychological complaints (anxiety, depression and sleep difficulties), work productivity and activity impairment, and self‐reported healthcare resource utilization. Bivariate and multivariate analyses for each outcome and comparative groups were conducted. Results This analysis included 769 CU and 7857 PsO (26.9% moderate/severe) patients. Following adjustment for covariates, CU patients showed a greater health‐related quality of life (HRQoL) impairment vs. overall PsO (MCS: −2.4, PCS: −1.6, SF‐6D: −0.03; all P < 0.001). CU patients showed a higher risk of anxiety, depression and sleep difficulties [odds ratio (OR): 1.63, 1.34 and 1.56, respectively; all P < 0.01] and greater healthcare resource use vs. overall PsO. The overall activity impairment was significantly greater in CU patients than in overall PsO patients (P = 0.001), while the impact on work was not significantly different. The results vs. moderate/severe PsO group showed no significant differences on all outcomes. Conclusion Burden of illness in CU is higher than PsO of all severities but similar to that observed in moderate/severe PsO. Both diseases have a similar negative impact on work productivity.

Abstract
Background Approximately 50% of patients with chronic idiopathic/spontaneous urticaria (CIU/CSU) report hives and angioedema; some experience hives/angioedema only. Objective Assess omalizumab's effect on angioedema and quality of life (QoL) in subgroups with refractory CIU/CSU: those with and without angioedema. Methods Patients received omalizumab (75, 150 or 300 mg) or placebo every 4 weeks for 12/24 weeks. Angioedema and QoL were assessed [Urticaria Patient Daily Diary and Dermatology Quality of Life Index (DLQI)]. Subgroups were based on the presence/absence of baseline angioedema 7 days prior to randomization. Results Patients with baseline angioedema randomized to omalizumab 300 mg had a greater reduction in mean weekly incidence of angioedema and mean number of days/week with angioedema vs. placebo at 12 and 24 weeks. A 3.3‐ to 4.5‐point greater mean reduction in DLQI score was achieved with omalizumab 300 mg treatment vs. placebo, above the minimal clinically important difference threshold. Results with lower doses vs. placebo were variable. Conclusion Compared with placebo, omalizumab 300 mg treatment over 12–24 weeks resulted in marked reduction in incidence and number of days/week with angioedema accompanied by clinically relevant improvement in QoL.

Abstract
PURPOSE To improve jugular central venous access device (CVAD) securement, prevent CVAD failure (composite: dislodgement, occlusion, breakage, local or bloodstream infection), and assess subsequent trial feasibility. MATERIALS AND METHODS Study design was a 4-arm, parallel, randomized, controlled, nonblinded, pilot trial. Patients received CVAD securement with (i) suture+bordered polyurethane (suture + BPU; control), (ii) suture+absorbent dressing (suture + AD), (iii) sutureless securement device+simple polyurethane (SSD+SPU), or (iv) tissue adhesive+simple polyurethane (TA+SPU). Midtrial, due to safety, the TA+SPU intervention was replaced with a suture + TA+SPU group. RESULTS A total of 221 patients were randomized with 2 postrandomization exclusions. Central venous access device failure was as follows: suture + BPU controls, 2 (4%) of 55 (0.52/1000 hours); suture + AD, 1 (2%) of 56 (0.26/1000 hours, P=.560); SSD+SPU, 4 (7%) of 55 (1.04/1000 hours, P=.417); TA+SPU, 4 (17%) of 23 (2.53/1000 hours, P=.049); and suture + TA+SPU, 0 (0%) of 30 (P=.263; intention-to-treat, log-rank tests). Central venous access device failure was predicted (P<.05) by baseline poor/fair skin integrity (hazard ratio, 9.8; 95% confidence interval, 1.2-79.9) or impaired mental state at CVAD removal (hazard ratio, 14.2; 95% confidence interval, 3.0-68.4). CONCLUSIONS Jugular CVAD securement is challenging in postcardiac surgical patients who are coagulopathic and mobilized early. TA+SPU was ineffective for CVAD securement and is not recommended. Suture + TA+SPU appeared promising, with zero CVAD failure observed. Future trials should resolve uncertainty about the comparative effect of suture + TA+SPU, suture + AD, and SSD+SPU vs suture + BPU.

Whole-genome sequencing reveals activation-induced cytidine deaminase signatures during indolent chronic lymphocytic leukaemia evolution. Nat Commun 2015; 6:8866.

Abstract
Patients with chromosome 13q deletion or normal cytogenetics represent the majority of chronic lymphocytic leukaemia (CLL) cases, yet have relatively few driver mutations. To better understand their genomic landscape, here we perform whole-genome sequencing on a cohort of patients enriched with these cytogenetic characteristics. Mutations in known CLL drivers are seen in only 33% of this cohort, and associated with normal cytogenetics and unmutated IGHV. The most commonly mutated gene in our cohort, IGLL5, shows a mutational pattern suggestive of activation-induced cytidine deaminase (AID) activity. Unsupervised analysis of mutational signatures demonstrates the activities of canonical AID (c-AID), leading to clustered mutations near active transcriptional start sites; non-canonical AID (nc-AID), leading to genome-wide non-clustered mutations, and an ageing signature responsible for most mutations. Using mutation clonality to infer time of onset, we find that while ageing and c-AID activities are ongoing, nc-AID-associated mutations likely occur earlier in tumour evolution. The oncogenic events driving indolent chronic lymphocytic leukaemia are relatively unknown. Here, the authors perform whole genome sequencing on 30 such tumours and identify recurrent mutations in IGLL5 and two activation induced cytidine deaminase signatures that are operative at different stages of CLL evolution.

Abstract
We report on the collapsing and reswelling ability of grafted poly(methyl vinyl ether) chains of different molecular architectures. In order to study the influence of constraints and confinement of the chains, the polymer was grafted onto AFM tips, as a model of a curved nano-sized surface, and onto macroscopic silicon substrates for comparison purposes. AFM-based force spectroscopy experiments were performed to characterise at the nanoscale the temperature-dependent collapsing process and the reversibility to the swollen state on both substrates. The reversible character of the thermoresponsive transition and its kinetics were shown to greatly depend on the polymer architecture and the constraints encountered by the chains.

Abstract
BACKGROUND AND PURPOSE CT is a ubiquitous, efficient, and cost-effective method to evaluate pediatric ventricular size, particularly in patients with CSF shunt diversion who often need emergent imaging. We therefore sought to determine the minimum dose output or CT dose index required to produce clinically acceptable examinations. MATERIALS AND METHODS Using a validated noise insertion method and CT projection data from 22 patients, standard pediatric head CT images were reconstructed with weighted filtered back-projection and sinogram-affirmed iterative reconstruction corresponding to routine, 25%, and 10% dose. Reconstructed images were then evaluated by 3 neuroradiologists (blinded to dose and reconstruction method) for ventricular size, diagnostic confidence, image quality, evidence of hemorrhage, and shunt tip location, and compared with the reference standard. RESULTS There was no significant difference in the ventricular size ranking, and the sensitivity for moderate to severe hydrocephalus was 100%. There was no significant difference between the full-dose level and the ventricular size rankings at the 25% or the 10% dose level for either reconstruction kernel (P > .979). Diagnostic confidence was maintained across doses and kernel. Hemorrhage was more difficult to identify as image quality degraded as dose decreased but was still seen in a majority of cases. Shunts were identified by all readers across all doses and reconstruction methods. CONCLUSIONS CT images having dose reductions of 90% relative to routine head CT examinations provide acceptable image quality to address the specific clinical task of evaluating ventricular size.

Abstract
On the basis of the perimeter model for 4N-electron [n]annulenes, algebraic expressions for the B values of perturbed four-membered rings (n = 4) with four ;r electrons (N = 1) have been derived. The results are used to interpret the MCD spectrum of l,3-di-fm-butyl-2,4-diethyI-1,3,2,4-diazadiboretidine.

Abstract
BACKGROUND Influenza is a major cause of morbidity and mortality. In 2011, influenza vaccination was provided free for people at greatest risk of severe disease: people aged 65 years and over, Aboriginal Australians 15 years and older, pregnant women, and individuals aged 6 months and over who suffered chronic medical conditions. AIMS To evaluate the Western Sydney and Nepean Blue Mountains Local Health District Influenza Prevention Program and to identify some of the enablers and barriers to vaccination in the hospital outpatient setting. METHODS Western Sydney and Nepean Blue Mountains local health districts' influenza prevention programme provided influenza vaccine in hospital outpatient settings between 21 March 2011 and 30 June 2011. Accredited nurse immunisers vaccinated 2824 individuals and recorded their primary reason for vaccination. Nurse immunisers were interviewed to identify barriers and enablers to influenza immunisation uptake. RESULTS Two thousand, eight hundred and twenty-four doses of influenza vaccine were administered to people at high risk of influenza in four hospitals in the region: two tertiary facilities and two district hospitals. The primary indication for vaccination was chronic disease in 50% and pregnancy in 37%. Estimated direct cost of the programme was $19 per dose. CONCLUSIONS A hospital-based influenza vaccination programme can be an effective way to improve influenza vaccination rates among specific population groups at high risk of severe disease with influenza, particularly pregnant women and those younger than 65 years with a chronic medical condition.
