Abstract
BACKGROUND Addressing health inequality with sexual and reproductive health requires an understanding of unmet need within a range of populations. This review examined the methods and definitions that have been used to measure unmet need, and the populations most frequently assessed. METHODS Five databases (PubMed, Web of Science, Scopus, The Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Health Management and Policy Database (HMIC)) were searched for studies that described quantitative measurement of unmet need within sexual and/or reproductive health between 2010 and 2021. A narrative synthesis was then undertaken to ascertain themes within the literature. RESULTS The database search yielded 19,747 papers; 216 papers were included after screening. 190 studies assessed unmet reproductive health need, of which 137 were analyses of trends among people living in low/lower-middle income countries; 181 used cross-sectional data, with only nine analyses being longitudinal. Eighteen studies analysed unmet sexual health need, of which 12 focused on high and upper-middle income populations. 16 papers used cross-sectional analyses. The remaining 10 studies examined unmet need for a combination of sexual and reproductive health services, eight among populations from upper-middle or high income countries. All were cross-sectional analyses. 165 studies used the Demographic and Health Surveys (DHS) definition of unmet need; no other standardised definition was used among the remaining papers. DISCUSSION There is a significant focus on unmet need for contraception among women in low income countries within the published literature, leaving considerable evidence gaps in relation to unmet need within sexual health generally and among men in particular, and unmet reproductive health need in high income settings. In addition, using an increased range of data collection methods, analyses and definitions of unmet need would enable better understanding of health inequality in this area.

Abstract
Introduction
Gonorrhoea is the second most commonly diagnosed sexually transmitted infection in England, and diagnoses among young women increased 31% between 2018 and 2019. Understanding the patterns of testing and diagnosis among young women is likely to aid prevention among the most vulnerable segments of this population.
Methods
Data on gonorrhoea diagnoses at sexual health services among women aged 16-24 in England were obtained using the GUMCAD STI Surveillance System. We investigated the relationship between two exposure variables (deprivation and ethnicity), and two outcome variables (number of gonorrhoea tests and number of gonorrhoea diagnoses). Poisson regression was used to calculate rate ratios for the relationship between the exposure and outcome variables. The testing analysis was offset for the size of the population, and the diagnosis analysis was offset for the number of tests within the population.
Results
Between 2012 and 2019, gonorrhoea testing and diagnosis rates were highest among women living in the most deprived areas. The rate of testing in the least deprived 10% of neighbourhoods was significantly lower than that seen in the most deprived 10% of neighbourhoods (rate ratio (RR) 0.79; 95% confidence interval 0.79 - 0.80), and the rate of diagnosis in the least deprived 10% of neighbourhoods was around a third of that seen in the most deprived 10% of neighbourhoods (0.35; 0.33 - 0.36). When compared to White British women, the rate of gonorrhoea diagnosis was lower among Bangladeshi (RR 0.89; 0.75 - 1.05), Indian (0.76; 0.68 - 0.84), Pakistani (0.87; 0.77 - 1.00) and Chinese women (0.60; 0.51 - 0.71) and was highest among Black Caribbean (2.26; 2.18 - 2.33) and Black African (1.40; 1.34 - 1.45) women.
Conclusions
This analysis found inequalities in the distribution of gonorrhoea among young women in England that may indicate structural barriers to STI prevention that are affecting Black women and those living within the most deprived populations.
Key messages
• Gonorrhoea testing rates among young women in England are highest among women from deprived areas and Black women.
• Gonorrhoea diagnosis rates among young women in England are highest among women from deprived areas and Black women.

Abstract
BackgroundThe Centers for Disease Control and Prevention recommends an additional dose (AddDose) of COVID-19 vaccine for moderately/severely immunosuppressed individuals following an initial vaccine series. The American College of Rheumatology suggests that patients interrupt use (hold) certain DMARDs around the time of COVID-19 vaccination to improve immunogenicity. Whether holding DMARDs around an AddDose of COVID-19 vaccine affects RA disease activity or affects frequencies of lymphocyte populations that may be associated with RA disease activity remains unknown.ObjectivesTo test whether RA disease activity and frequencies of lymphocyte populations change pre- vs. post-AddDose of COVID-19 vaccine, overall and stratified by holding vs. continuation of DMARDs around the AddDose.MethodsProspective observational cohort study of patients with RA who had completed an initial COVID-19 vaccine series (2 doses of mRNA vaccine or 1 dose of adenovirus vector vaccine). Subjects enrolled July-November 2021, prior to receiving an AddDose. Subjects held or continued DMARDs around the AddDose based on discussion with their rheumatologist and/or personal decision-making. RA disease activity was assessed weekly using the validated patient-reported RA Disease Activity Index-5 (RADAI-5) from enrollment through 4 weeks post-AddDose. We compared mean RADAI-5 pre- vs. post-AddDose using generalized estimating equations to account for correlated data among individual subjects. We aimed to enroll 60 subjects to achieve 91% power to detect a 15% non-inferiority margin in mean RADAI-5 post- vs. pre-AddDose. A subset of subjects with seropositive RA provided blood for flow cytometry at enrollment and week 4 post-AddDose. Frequencies of lymphocyte populations (T peripheral helper [Tph] cells, T follicular helper [Tfh] cells, age-associated B cells [ABC], and plasmablasts) were compared pre- vs. post-AddDose using Wilcoxon paired tests with Bonferroni correction.ResultsAmong 71 subjects, mean age was 62 (SD 12) years, 85% were female, and 87% had seropositive RA. Methotrexate (42%) and TNF inhibitors (38%) were the most common DMARDs; 21% were taking prednisone. One subject reported COVID-19 infection prior to the AddDose. The mean RADAI-5 was 3.20 (SD 0.23) pre-AddDose compared to 3.25 (SD 0.23) after (difference of 1.6%, p=0.51). Figure 1 displays mean RADAI-5 in 35 (49%) subjects that held at least 1 DMARD and 36 (51%) subjects that continued all DMARDs around the AddDose. Mean change in RADAI-5 between pre- vs. post-AddDose did not significantly differ based on whether subjects held vs. continued DMARDs (p for interaction = 0.16). Frequencies of Tph, Tfh, ABC, and plasmablast populations did not significantly differ between the pre- and post-AddDose timepoints in subjects that held at least 1 DMARD (n=16) or subjects that continued all DMARD (n=11) (Figure 1).ConclusionRA disease activity, measured weekly with a validated patient-reported outcome, is stable around the time of an AddDose of COVID-19 vaccine. Lymphocyte subsets of interest in RA were also similar before and after the AddDose, supporting the observation of stable patient-reported RA disease activity. Holding DMARDs was not associated with greater RA disease activity following the AddDose.Disclosure of InterestsSara Tedeschi Consultant of: NGM Biopharmaceuticals: payment to Dr. Tedeschi, Grant/research support from: Moderna: research support to institution, Jacklyn Stratton: None declared, Jack Ellrodt: None declared, Mary Grace Whelan: None declared, Keigo Hayashi: None declared, Kazuki Yoshida Consultant of: OM1, Inc: consulting fees paid to Dr. Yoshida, Lin Chen: None declared, Ifeoluwakiisi Adejoorin: None declared, Kathryne E.

Abstract
Background:Low-dose methotrexate (LD-MTX) is a common first-line treatment for systemic rheumatic diseases, and its use is contraindicated in advanced chronic kidney disease (CKD) because it is primarily excreted by the kidneys. Among patients with preserved kidney function, the safety of LD-MTX on estimated glomerular filtration rate (eGFR) and kidney adverse events (AEs) has not been established.Objectives:To investigate the effect of LD-MTX on eGFR and kidney AEs using data from a randomized clinical trial.Methods:We performed a secondary analysis for eGFR and kidney AEs using the randomized double-blind, placebo-controlled Cardiovascular Inflammation Reduction Trial. Adults with known cardiovascular disease and diabetes and/or metabolic syndrome were randomly allocated to oral LD-MTX (target dose 15-20 mg/week) or placebo. All participants took folic acid 1 mg six days/week. Exclusion criteria included systemic inflammatory disease and creatinine clearance <40 mL/min (by Cockcroft-Gault). eGFR was calculated using the CKD-EPI formula. Clinical kidney AEs were blindly adjudicated. The least-squares mean change of eGFR from baseline was calculated at each study visit; the difference in eGFR slopes between LD-MTX and placebo was compared using a modified intention-to-treat approach. We also compared rates of kidney AEs for LD-MTX versus placebo using Cox proportional hazards models.Results:A total of 2,391 subjects were randomized to LD-MTX and 2,395 to placebo. At baseline, mean age was 66 years, 19% were female, mean eGFR was 80.0 mL/min/1.73m2, and 18% had stage 3 CKD or worse. Median follow-up duration was 23 months, and median LD-MTX dose was 16 mg/week. Those randomized to LD-MTX had less decline in eGFR over the entire follow-up compared to placebo (slope difference 1.12, 95%CI 0.59-1.65, p<0.001, Figure 1). Those with CKD stage 3 or worse on LD-MTX saw less eGFR decline than those with CKD stage 2 or better (slope difference among CKD stage 3 or worse: 2.46, 95%CI 1.10-3.82, p<0.001; p for interaction 0.02). The LD-MTX group had higher eGFR than placebo over the first 24 months of study follow-up (p<0.05 at each visit). On safety laboratory monitoring, there were 159 acute kidney injury AEs in the LD-MTX group and 187 in the placebo group (HR 0.83, 95%CI 0.67-1.02, Table 1). There were 37 clinical kidney AEs in the LD-MTX group and 42 in the placebo group (0.87, 95%CI 0.56-1.36). One subject began dialysis in the LD-MTX group compared to 3 in the placebo group.Table 1.Rates and hazard ratios for kidney adverse events per random assignment of low-dose methotrexate or placebo in the Cardiovascular Inflammation Reduction Trial (n=4,786).Low-dose methotrexate (n=2,391)Placebo (n=2,395) (reference)HR (95%CI)EventsRate per 100 person-years (95%CI)EventsRate per 100 person-years (95%CI)SCr collected at safety visitsAny event*1593.42 (2.93, 3.98)1874.06 (3.53, 4.67)0.83 (0.67, 1.02)Mild (SCr 1.5-1.9x baseline)1543.47 (2.97, 4.06)1774.06 (3.51, 4.69)0.85 (0.68, 1.06)Moderate (SCr 2-2.9x baseline)190.41 (0.26, 0.64)240.52 (0.35, 0.78)0.78 (0.43, 1.43)Severe (SCr ≥3x baseline)20.04 (0.01, 0.17)50.11 (0.05, 0.26)0.40 (0.08, 2.04)Adjudicated clinical kidney adverse eventsAny event*370.80 (0.58, 1.11)420.92 (0.68, 1.24)0.87 (0.56, 1.36)Mild240.52 (0.35, 0.77)250.55 (0.37, 0.81)0.95 (0.55, 1.67)Moderate110.24 (0.13, 0.43)110.24 (0.13, 0.43)1.00 (0.43, 2.29)Severe40.09 (0.03, 0.23)80.17 (0.09, 0.35)0.50 (0.15, 1.64)New dialysis10.02 (0.00, 0.15)30.17 (0.09, 0.35)0.34 (0.04, 3.17)*Acute kidney injury presence and severity was defined by KDIGO (Kidney Disease: Improving Global Outcomes) classification.CI, confidence interval; HR, hazard ratio; SCr, serum creatinine.Conclusion:These results demonstrate the kidney safety of LD-MTX among patients without advanced CKD at baseline.

Abstract
Background:Rheumatoid arthritis (RA) patients have an increased risk of cardiovascular (CV) events not fully explained by traditional CV risk factors. The relationship between fluctuating inflammation due to RA disease activity and CV events is of interest.Objectives:To examine the influence of time-varying disease activity on the subsequent risks of CV disease.Methods:We followed patients from a large US registry of clinically diagnosed RA patients, starting at their first visit with a Clinical Disease Activity Index (CDAI) through the end of follow-up or first CV event. Exposure of interest was disease activity measured by categorical CDAI (high, moderate, low, and remission) averaged within each 6-month window. The outcome of interest was major adverse CV events (MACE) defined as non-fatal myocardial infarction, non-fatal stroke (excluding transient ischemic attacks), and CV death. For baseline confounders we considered age, gender, race, disease duration, Health Assessment Questionnaire, hypertension, diabetes, hyperlipidemia, family history of premature (age<50) CV events, and RF/ACPA seropositivity. For time-varying variables we considered tumor necrosis factor inhibitor (TNFi), non-TNFi biologic, methotrexate, oral glucocorticoid, non-steroidal anti-inflammatory drugs, statin, and aspirin use. We used the marginal structural model (MSM) framework to examine the impact of CDAI at each 6-month interval on MACE. We estimated time-varying hazard ratios (HRs) comparing high CDAI during follow-up to CDAI remission. Several predicted survival curves were constructed under different hypothetical CDAI scenarios, such as early and late transition to CDAI remission.Results:40,721 patients were eligible for our analyses. 77% were female and 84% were Caucasian. The mean age was 58 (SD 13) years with mean disease duration of 8.8 (median 5) years. Mean CDAI at their first registry visit was 14 (SD 13; remission 19%, low 31%, moderate 28%, and high 22%). Other baseline characteristics include: 41% current/former smokers, 31.5% with hypertension, 8.6% with diabetes, 18% with hyperlipidemia, and 52% seropositive. The average follow-up duration after baseline was 4.4 (median 3.3; max. 17.6) years. The crude event count of MACE was 1,050 events / 180,402 person-years.In the MSM analysis, the average HRs, assuming a constant HR, were 1.31 [0.90, 1.90] for low, 1.46 [1.01, 2.10] for moderate, and 1.43 [0.89, 2.31] for high CDAI disease activity categories during each 6-month interval. When approximating time-varying HR with linear trends, the highest estimates during the first 6 months of follow up were 1.61 [0.93, 2.77] for low CDAI, 1.97 [1.13, 3.43] for moderate CDAI, and 2.11 [1.13, 3.96] for high CDAI. These HRs gradually diminished during the follow up (Table). When we constructed hypothetical survival curves with transition to CDAI remission at different time points, earlier transition to CDAI remission was related to better event-free survival (Figure).Table 1.Time-varying hazard ratio estimates [95% confidence intervals] by duration in studyDisease activity measured by CDAIYearRemissionLowModerateHigh0.51.00 [ref]1.61 [0.93, 2.77]1.97 [1.13, 3.43]2.11 [1.13, 3.96]11.00 [ref]1.54 [0.97, 2.44]1.85 [1.17, 2.93]1.94 [1.13, 3.31]21.00 [ref]1.42 [1.00, 2.01]1.63 [1.16, 2.29]1.62 [1.04, 2.54]31.00 [ref]1.31 [0.90, 1.90]1.43 [0.97, 2.11]1.36 [0.80, 2.31]41.00 [ref]1.20 [0.72, 2.02]1.26 [0.72, 2.21]1.14 [0.55, 2.36]51.00 [ref]1.11 [0.54, 2.26]1.11 [0.51, 2.42]0.96 [0.36, 2.53]Figure 1.MACE-free survival curves under hypothetical CDAI scenariosConclusion:High and moderate CDAI were associated with higher hazard of MACE during the earlier period of follow-up, but the increased hazard diminished over time.

Abstract
Background:Denosumab is effective for osteoporosis, but discontinuation leads to rapid reversal of its therapeutic effect[1].Objectives:To estimate the risk for fracture among users of denosumab who delayed subsequent dosages compared with users who received dosages on time.Methods:Population-based cohort study. We included patients aged over 45 years who initiated denosumab for osteoporosis from UK THIN database, 2010 to 2019. Observational data were used to “emulate a hypothetical trial”[2, 3] with three dosing intervals: subsequent denosumab injection 24-28 weeks after prior dose (“on time”), delay by 4-16 weeks (“short delay”), and delay by over 16 weeks (“long delay”). The primary outcome was a composite of all fracture types. Secondary outcomes included major osteoporotic fracture, vertebral fracture, and hip fracture.Results:The rate of composite fracture per 1000 person-years was 58.9 for on-time, 61.7 for short delay, and 85.4 for long delay of subsequent denosumab injections. Compared to on-time injections, short delay had a hazard ratio (HR) for composite fracture 1.03 (95% CI 0.63-1.69) and long delay HR 1.44 (95% CI 0.96-2.17; p for trend 0.093). For major osteoporotic fractures, short delay had an HR 0.94 (95% CI 0.57-1.55) and long delay an HR of 1.69 (95% CI 1.01-2.83; p for trend 0.056). For vertebral fractures, short delay had an HR 1.48 (95% CI 0.58-3.79) and long delay 3.91 (95% CI 1.62-9.45; p for trend 0.005).Conclusion:While delayed subsequent denosumab dosages over 16 weeks was associated with an increased risk of vertebral and major osteoporotic fracture compared to no delay, composite fracture risk was not increased with longer delays.References:[1]Cummings SR, Ferrari S, Eastell R, et al.

Abstract
Background:Patients with rheumatoid arthritis (RA) are at increased risk of serious infections, with considerable excess morbidity and mortality after pneumonia. RA-related autoantibodies such as anti-cyclic citrullinated peptide (CCP) and rheumatoid factor (RF) may be generated at inflamed pulmonary mucosa prior to clinical RA onset. Therefore, patients with seropositive RA may be at increased risk for pneumonia after RA diagnosis due to subclinical pulmonary injury.Objectives:We investigated whether seropositive RA was associated with increased pneumonia risk compared to seronegative RA.Methods:We performed a retrospective cohort study among RA patients seen at a health care system in Boston, MA. RA patients were identified using a previously validated electronic health record (EHR) algorithm incorporating billing codes, natural language processing (NLP) of notes, medications, and laboratory results at 97% specificity1. We constructed an incident RA cohort using NLP for the index date of initial mention of RA. All patients were required to have both CCP and RF data from clinical care to determine serologic RA phenotype. We used semi-supervised machine learning approaches to identify pneumonia using billing codes and terms extracted using NLP, with the Centers for Disease Control definition of pneumonia from medical record review as a gold standard. The area under the receiver operating curve (AUROC) for this billing code+NLP pneumonia algorithm was 0.94 compared to the standard rule-based pneumonia algorithm (billing code on inpatient discharge) AUROC of 0.86 (p<0.001). Smoking status was extracted using NLP methods. Other covariates, including a previous validated weighted RA multimorbidity score2, were determined using structured EHR data. We used Cox regression to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for pneumonia adjusting for potential confounders.Results:We analyzed a total of 4,110 patients with incident RA and both CCP/RF data available. Mean age at index date was 53.0 years (SD 14.8), 77.2% were female, and 79.8% were CCP+ or RF+. During 32,248 patient-years of follow-up (mean 7.8 years/patient), we identified 240 pneumonia cases. Patients with seropositive RA had a HR of 1.99 (95%CI 1.30-3.01, Table) for pneumonia compared to patients with seronegative RA, adjusted for age, sex, smoking, index year, ESR level, glucocorticoid use, DMARD use, and weighted RA multimorbidity score. While CCP+ RA (HR 1.91, 95%CI 1.23-2.97) and RF+ RA (HR 2.07, 95%CI 1.35-3.16) had increased pneumonia risk compared to seronegative RA, the CCP+RF- RA subgroup had no association with pneumonia (HR 0.67, 95%CI 0.23-1.93).Conclusion:Patients with incident seropositive RA, particularly RF+ RA, had increased risk for pneumonia throughout the RA disease course that was not explained by measured confounders including smoking status, multimorbidity, medications, and ESR level. Further studies should investigate how RF+ may predispose RA patients to later develop pneumonia after clinical RA diagnosis.References:[1]Liao KP, Cai T, Gainer V, et al.

Abstract
Background:Methods used in observational comparative effectiveness research (CER) are highly variable. Target trial emulation is an intuitive design approach that encourages researchers to formulate their question as a hypothetical randomised controlled trial (RCT), or the “target trial”. Using observational data to emulate the target trial helps avoid common biases and has been shown to better align results with actual RCTs.Objectives:We systematically reviewed observational CER studies in rheumatoid arthritis to provide examples of design issues that might have been avoided by using target trial emulation.Methods:We searched for head-to-head effectiveness comparisons of biologic DMARDs in RA. Study designs were reviewed for components of target trial emulation: 1) eligibility criteria, 2) treatment strategies, 3) assignment procedures, 4) follow-up period, 5) outcome, 6) causal contrasts of interest (i.e., intention-to-treat or per-protocol effect), and 7) analysis plan. Reported methods were taken as the “emulation” of a corresponding target trial, to assess design issues that might introduce bias.Results:We found 31 CER studies, the majority of which had one design issue belonging to one of the 7 protocol components (Table 1). The most common issues were: 1) 17 out of 31 studies used post-baseline information to define baseline eligibility (e.g. requiring ≥1 follow-up), which can bias results; 2) 26 out of 31 studies did not declare their causal contrast of interest, which is often made difficult by issue 1 and impacts data analysis and interpretation; and 3) 9 out of 31 studies used statistical selection of confounders rather than pre-defining them, which can also introduce bias (e.g. through adjustment of collider or intermediate variables).Table 1.Design issues identified in 31 studies and reasons why they do not correspond to well-defined “target trials”Design issues identified in study methodsHow these issues can be conceptualized in a RCT protocol1. Eligibility criteriaPost-baseline data requirement (17 out of 31 studies).Impossible to use future data at enrolment.Differential eligibility for each arm (5 studies).Breaks the notion of one group of people randomized to 2+ arms.2.

Follow-upUnspecified follow-up duration in longitudinal analyses (5 studies)Infeasible to conceive an RCT with unspecified duration. Analysis results may lack interpretability.5. OutcomeJoint outcome of remaining on treatmentandhaving a good response, to avoid missingness (3 studies)Unusual outcome for RCT although technically possible.6.

Abstract
Background:Patients undergoing total knee replacement (TKR) are at increased risk of persistent opioid use and dependenceObjectives:To identify patients with persistent high-dose opioid use after TKR using group-based trajectory models (GBTM) and determine predictors of persistent high-dose opioid users using pre-TKR patient characteristicsMethods:Using US Medicare claims (2010-2014), we identified patients aged ≥65 years who underwent a TKR and had no history of cancer or high-dose opioid use (>25 mean morphine equivalents (MME)/day) in the year prior. All patients were continuously enrolled in Medicare for ≥360 days prior to and ≥30 days after the TKR. To determine opioid filling patterns after the surgery, patients were followed up to 360 days from the day of TKR. We modeled 12 monthly indicators of opioid prescription fills as a continuous (MME/day) variable using a censored normal GBTM and categorized patients into 4 groups. The primary outcome was persistent high-dose opioid use defined as patients in trajectory Group 3 (38.8 MME/day) or Group 4 (22.4 MME/day). We split the data into training (2010-2013 data) and test (2014 data) sets and used logistic regression to predict high-dose opioid use vs low-dose opioid use (Groups 1 and 2) as a binary outcome utilizing pre-TKR patient characteristics as candidate predictors using the least absolute shrinkage and selection operator (LASSO) regression for variable selection. A reduced model with only 10 pre-specified variables readily available for clinical use was also consideredResults:The final study cohort included 142,089 patients. The GBTM identified 4 distinct trajectories (Group 1- Short-term, low-dose, Group 2- long-term, low-dose, Group 3- medium-term, high-dose, Group 4-long-term, high-dose) of opioid use in the year after TKR(Figure). Using logistic regression and LASSO, we predicted the probability of persistent high-dose opioid use (N=17,171) (vs. low-dose opioid use) in the training set (N=101,810) for an AUC=0.80. The AUC in the test set (N=40,279) predicting high opioid use (N=5,893) was 0.77. The final model selected 33 variables and identified baseline history of opioid use as the strongest positive predictor of high-dose persistent opioid use. The reduced model with only ten predictors also performed equally well (AUC=0.77)(Table).Conclusion:In this cohort of older patients with no history of cancer or high-dose opioid use at baseline, 16.2% became high dose (28.1 MME/day) opioid users during the year after TKR. Our prediction model with 10 readily available clinical factors may help identify patients at high risk of future adverse outcomes from persistent opioid use and dependence after TKRFigure.

Abstract
Background:Remission is the preferred treatment target in rheumatoid arthritis (RA), and many patients require biologic DMARDs to reach this state. It is debated whether tapering of tumor necrosis factor inhibitor (TNFi) treatment to discontinuation should be considered in RA patients who sustain remission on treatment (1).Objectives:The primary study objective was to assess the effect of tapering and withdrawal of TNFi on the risk of flares in RA patients in clinical remission.Methods:In the non-inferiority ARCTIC REWIND trial, RA patients in remission for at least 12 months on stable TNFi therapy were randomly assigned to continued stable TNFi or tapering (half-dose TNFi for 4 months, thereafter withdrawal of TNFi), with visits every four months. csDMARD co-medication was kept stable in both arms. Patients had to be in DAS remission at inclusion with 0/44 swollen joints. The primary endpoint was the proportion of patients with disease flare during the 12-month study period (defined as DAS>1.6, change in DAS>0.6 and 2 or more swollen joints, or the physician and patient agreed that a clinically significant flare had occurred). Full-dose TNFi was reinstated in case of flares in the tapering arm. The non-inferiority margin was 20%, with a predefined superiority test if non-inferiority was not shown. The inferiority null-hypothesis was tested in the per-protocol population by mixed effect logistic regression. Radiographs were scored by van der Heijde modified Sharp score (0 and 12 months, average of two readers, progression: ≥1 unit change). ClinicaltrialsNCT01881308.Results:We randomised 99 patients, 92 received the allocated treatment strategy, 84 were included in the per-protocol population. Baseline characteristics, clinical and ultrasound disease activity were balanced (Table). csDMARD co-medication was used by 93% in the stable and 88% in the tapering arm. In the primary analysis, 5% of patients in the stable TNFi arm experienced a flare during 12 months, compared to 63% in the tapering TNFi arm. The risk difference (95% CI) was 58% (42% to 74%, Fig 1), with stable treatment being deemed superior to tapering. 90% in the stable and 81% in the tapering arm did not show progression of radiographic joint damage, difference (95% CI) -9% (-24%, 6%). At 12 months, DAS scores, DAS remission and function were similar between groups (Fig 2). The numbers of adverse events (AE)/serious AE in the stable and tapering arm were 57/2 and 50/3, respectively, with 26 and 15 infections.Conclusion:In a randomised clinical trial assessing patients in prolonged and deep RA remission, we observed a large increase in the flare rate in patients who tapered and discontinued TNFi. Patients responded well to reinstated treatment and remission rates in the two study arms were comparable at 12 months.References:[1]Smolen et al.

Abstract
Background:Sustained remission is the goal of rheumatoid arthritis (RA) care, and more patients reach and maintain this state on conventional synthetic disease modifying anti-rheumatic drugs (csDMARDs) with treat-to-target strategies. The knowledge about whether csDMARDs can be tapered in RA remission is limited.Objectives:The primary objective of the study was to assess the effect of tapering of csDMARDs on the risk of flares in RA patients in sustained clinical remission.Methods:In the open, phase 4, non-inferiority ARCTIC REWIND trial, RA patients in clinical remission for ≥ 12 months on stable csDMARD therapy were randomised to continued stable csDMARD or half dose csDMARD. Patients had to be in DAS remission at inclusion with no swollen joints (of 44). The primary endpoint was the proportion of patients with a disease flare during 12 months (defined as a combination of DAS >1.6, change in DAS >0.6 and ≥2 swollen joints, or the physician and patient agreed that a clinically significant flare had occurred). Patients attended visits every 4 months, with extra visits in case of flares. The non-inferiority margin was 20%, with a predefined superiority test if non-inferiority was not shown. Mixed effect logistic regression was used to test the inferiority null-hypothesis in the per-protocol population. Radiographs at 0 and 12 months were scored by van der Heijde Sharp score (average score of two readers, progression: ≥1 unit change/year). Clinicaltrials.govNCT01881308.Results:We enrolled 160 patients, 155 received the allocated treatment strategy. Baseline characteristics were overall well balanced (Table). 78% of patients in the stable csDMARD arm and 84% in the half-dose csDMARD arm used methotrexate monotherapy. In the primary analysis, we observed flares in 6% of patients on stable csDMARD, compared to 25% in the half-dose csDMARD arm, giving a risk difference (95% CI) of 18.3% (7.2% to 29.3%, Fig 1). Non-inferiority could not be claimed, with the results showing superiority of the stable arm over the half-dose arm (Fig 1). Similar results were found in methotrexate monotherapy users. In the stable arm, 2/5 (40%) escalated DMARD medication following the flares, compared to 18/19 (95%) in the tapering arm. No progression of radiographic joint damage was observed in 79.5% of patients on stable DMARDs and 62.7% of those tapering, difference (95% CI) -17.7% (-33.0%, -2.3%, Fig 2E). At 12 months, 92% of patients in the stable and 85% of patients in the tapered arm were in DAS remission (Fig 2C). The frequency of adverse events was 75 in the stable arm and 53 in the tapered arm, with serious adverse events in 2 (2.6%) of patients in the stable and 4 (5.1%, including two serious infections) patients in the tapered arm.Conclusion:In RA patients in sustained remission on csDMARDs, continued csDMARD therapy with stable dosage led to significantly fewer disease activity flares and less frequent radiographic joint damage progression than tapered csDMARD treatment.Table.Baseline values; mean (SD), n (%) or median (IQR)Stable, n=78Tapering, n=78Age, yrs55 (12)56 (12)Female50 (64%)54 (69%)ACPA+57 (73%)63 (81%)Symptom dur., yrs3.7 (1.8)3.4 (1.4)DAS0.8 (0.4)0.8 (0.3)CRP mg/L2 (1, 3)2.0 (1,3)MTX monotherapy61 (78%)65 (84%)Disclosure of Interests:Siri Lillegraven: None declared, Nina Paulshus Sundlisæter: None declared, Anna-Birgitte Aga: None declared, Joe Sexton: None declared, Inge Olsen: None declared, Hallvard Fremstad: None declared, Cristina Spada: None declared, Tor Magne Madland: None declared, Christian A.

Abstract
Male migrant workers (MMWs) in India are vulnerable to developing alcohol-related problems and engaging in unprotected sex, putting them at risk of HIV. Research has shown that alcohol-related expectancies mediate vulnerability to alcoholism. We examined which expectancies were associated with sexual risk and drinking. We surveyed 1085 heterosexual MMWs in two South Indian municipalities, assessing expectancies, sex under the influence, and unprotected sex with female sex workers (FSW) and casual female partners in the prior 30 days. Men more strongly endorsed positive than negative expectancies (t = 53.59, p < .01). In multivariate logistic regression, the expectancy of having more fun helped drive the combination of alcohol and unprotected sex with FSW partners (OR = 1.22, p < .05), whereas the expectancy of better sex helped drive a similar combination with casual partners (OR = 1.24, p < .01). Men concerned about alcohol-induced deficits were less likely to drink with FSW partners (OR = 0.81, p < .01), but more likely to have unprotected sex with them (OR = 1.78, p < .01). To reduce risk, MMWs would benefit from combination prevention approaches that use behavioral strategies to address drinking norms and awareness of risk, while using biomedical strategies to reduce viral transmission when risk does occur.

Abstract
Mobile phones remain a largely untapped resource in the ongoing challenge to address Female Sex Worker (FSW) health, including HIV prevention services, in India. An important step towards designing effective mobile phone-based initiatives for FSWs is clarifying the contextual influences of mobile phone solicitation on sexual risk behavior. In this paper, we extend previously identified associations between mobile phone solicitation and condom practices by examining whether this association is moderated by sex work pay and offer key considerations for future research and implementation. Specifically, we conducted an analysis among 589 Indian FSWs, where FSWs who did not use mobile phones to solicit clients had the lowest mean sex work pay (INR 394/ USD 6.54) compared to FSWs who used both mobile and traditional strategies (INR 563/ USD 9.34). Our analysis indicate low paid FSWs who used mobile phones concurrently with traditional strategies had 2.46 times higher odds of inconsistent condom use compared to low paid FSWs who did not use mobile phones for client solicitation. No such effect was identified among high paid FSWs. These findings also identified group level differences among FSWs reporting different mobile phone solicitation strategies, including violence, client condom use and HIV status. Our results indicate that low pay does moderate the association between mobile phone solicitation and condom practices, but only among a sub-set of low paid FSWs. These findings also demonstrate the utility of classification by different mobile phone solicitation strategies for accurate assessment of sexual risk among mobile phone soliciting FSWs. In turn, this paves the way for novel approaches to utilize mobile phones for FSW HIV prevention. We discuss one such example, a mobile phone-based rapid screening tool for acute HIV infection targeting Indian FSWs.

Examination of the recommended safe and unsafe zone for placement of surgical instruments in thoracentesis and video-assisted thoracic surgery: a cadaveric study. Folia Morphol (Warsz) 2015; 75:240-244.

Abstract
BACKGROUND Thoracentesis and video-assisted thoracic surgery procedures can result in haemorrhage as a consequence of severing the collateral branches of the posterior intercostal artery. These branches have been shown to be most common in the 5th intercostal space (ICS). Tortuosity has been shown to be especially prevalent nearer to midline. A group of investigators have recommended the 4th and 7th ICS, 120 mm lateral to midline as a safe zone, least likely to hit branches when cutting into the ICS. The present study aimed to investigate that safe zone as a better entry points for procedures. In addition, investigation of the least safe 5th ICS was also performed. MATERIALS AND METHODS A total of 56 embalmed human cadavers were selected for the study. With the cadavers laid prone, 2 cm incisions were made at the 4th, 5th and 7th ICS, 120 mm lateral to midline bilaterally. The cadavers were then placed supine and the incisions were dissected. Careful attention was paid to identify if any collateral branches were cut. RESULTS After thorough dissection of the 4th, 5th and 7th ICS incision sites, it was shown that damage to the 5th intercostal was seen most frequently. CONCLUSIONS Based on this cadaveric study, a 2 cm incision at the 4th, 5th and 7th ICS 120 mm lateral from midline resulted in the most damage at the level of the 5th ICS. The 4th ICS had the least damage seen. Therefore, it is recommended that insertion should be placed at the level of the 4th ICS bilaterally.

Abstract
AIM Symptomatic diverticular disease (DD) may be increasing in incidence in western society particularly in younger age groups. This study aimed to describe hospital admission rates and management for DD in Scotland between 2000 and 2010. METHOD Data were obtained from the Scottish Morbidity Records (SMR01). The study cohort included all patients with a hospital admission and a primary diagnosis of DD of the large intestine (ICD-10 primary code K57). RESULTS Scottish NHS hospitals reported 90 990 admissions for DD (in 87 314 patients) from 2000 to 2010. The annual number of admissions increased by 55.2% from 6591 in 2000 to 10,228 in 2010, an average annual increase per year of 4.5%. Most of the increase attributable to DD was due to elective day cases (3618 in 2000; 6925 in 2010) a likely consequence of a greater proportion of the population accessing colonoscopy over that time period. There was an 11% increase in inpatient admissions (2973-3303), 60% of these patients being women. Admissions in younger age groups increased proportionally in the later years of the study, and there was an association between DD admissions and greater deprivation. Despite an increase in complicated DD from 22.9% in 2000 to 27.1% in 2010 and a 16.8% increase in emergency inpatient admissions, the rate of surgery fell during the period of study. CONCLUSION This report supports findings of other population-based studies of western countries indicating that DD is an increasing burden on health service resources, particularly in younger age groups.

Abstract
The aim of this study was to examine female sex workers' solicitation of clients using mobile phones and the association between this and condom use with clients. Cross-sectional data were utilised to address the study's aim, drawing on data collected from female sex workers in Calicut, Kerala, and Chirala, Andhra Pradesh. Use of mobile phone solicitation was reported by 46.3% (n = 255) of Kerala participants and 78.7% (n = 464) of those in Andhra Pradesh. Kerala participants reporting exclusive solicitation using mobile phones demonstrated 1.67 times higher odds (95% CI: 1.01-2.79) of inconsistent condom use than those reporting non-use of mobile phones for solicitation. However, those reporting exclusive solicitation through mobile phones in Andhra Pradesh reported lower odds of inconsistent condom use (OR: 0.03; 95% CI: 0.01-0.26) than those not using mobile phones for solicitation. Findings indicate that solicitation of clients using mobile phones facilitates or hampers consistency in condom use with clients depending on the context, and how mobile phones are incorporated into solicitation practices. Variations in sex work environments, including economic dependence on sex work or lack thereof may partially account for the different effects found.

Abstract
BACKGROUND Past studies with ulcerative colitis (UC) patients indicate that disease activity strongly predicts health-related quality of life (HRQL). AIM To examine the degree to which daily treatment with MMX mesalazine predicts improved HRQL for patients with active UC and with stable HRQL for patients with quiescent UC. METHODS Data from two phases of a multicentre open-label trial were examined. In the acute phase, 132 patients with mild-to-moderate active UC received MMX mesalazine 2.4-4.8 g/day for 8 weeks, while 206 patients with quiescent UC received MMX mesalazine 2.4 g/day for a 12-month maintenance phase. Disease-specific HRQL was measured at baseline and endpoint of each phase using the Short Inflammatory Bowel Disease Questionnaire (SIBDQ). Repeated-measures anova models examined baseline-endpoint changes in SIBDQ, stool frequency (SF), and rectal bleeding severity (RBS). Correlations assessed the associations between SIBDQ and SF/RBS scores, while ancova techniques tested the sensitivity of SIBDQ to disease recurrence. RESULTS SIBDQ scores significantly increased for active mild-to-moderate UC patients following 8 weeks of treatment, while SIBDQ scores remained stable for quiescent UC patients following 12 months of treatment. Changes in SIBDQ scores correlated significantly with changes in SF and RBS scores. Patients with recurrent UC at maintenance phase endpoint had significantly lower SIBDQ scores than nonrecurrent patients. CONCLUSIONS Daily MMX mesalazine therapy was associated with significant improvement in disease-specific HRQL for patients with mild-to-moderate active UC and with the maintenance of HRQL for patients with quiescent UC. In both patient groups, HRQL was significantly associated with disease activity.

Evidence needed to manage freshwater ecosystems in a changing climate: turning adaptation principles into practice. THE SCIENCE OF THE TOTAL ENVIRONMENT 2010; 408:4150-64.

Abstract
It is widely accepted that climate change poses severe threats to freshwater ecosystems. Here we examine the scientific basis for adaptively managing vulnerable habitats and species. Our views are shaped by a literature survey of adaptation in practice, and by expert opinion. We assert that adaptation planning is constrained by uncertainty about evolving climatic and non-climatic pressures, by difficulties in predicting species- and ecosystem-level responses to these forces, and by the plasticity of management goals. This implies that adaptation measures will have greatest acceptance when they deliver multiple benefits, including, but not limited to, the amelioration of climate impacts. We suggest that many principles for biodiversity management under climate change are intuitively correct but hard to apply in practice. This view is tested using two commonly assumed doctrines: "increase shading of vulnerable reaches through tree planting" (to reduce water temperatures); and "set hands off flows" (to halt potentially harmful abstractions during low flow episodes). We show that the value of riparian trees for shading, water cooling and other functions is partially understood, but extension of this knowledge to water temperature management is so far lacking. Likewise, there is a long history of environmental flow assessment for allocating water to competing uses, but more research is needed into the effectiveness of ecological objectives based on target flows. We therefore advocate more multi-disciplinary field and model experimentation to test the cost-effectiveness and efficacy of adaptation measures applied at different scales. In particular, there is a need for a major collaborative programme to: examine natural adaptation to climatic variation in freshwater species; identify where existing environmental practice may be insufficient; review the fitness of monitoring networks to detect change; translate existing knowledge into guidance; and implement best practice within existing regulatory frameworks.

Abstract
This qualitative study examines the role of alcohol in sexual risk among male migrant workers and female sex workers in two South Indian states. Most men reported using alcohol for increased energy and courage prior to their sexual experiences and to reduce feelings of loneliness and isolation. Sex workers, on the other hand, often stated that they avoided alcohol prior to sex in order to stay alert and reduce the risk of violence. Both groups reported that drinking often increased male aggression and reduced condom use. Research is needed to examine the prevalence of these patterns as well as factors associated with sexual risk and violence, in order to develop targeted interventions for these groups. Future risk reduction programs may benefit from addressing safer ways of meeting the needs expressed by the participants. This may include strategies to defuse volatile situations, safe ways of improving the sexual experience, and interventions aimed at alleviating loneliness and isolation for migrants.

Abstract
Airway smooth muscle (ASM) plays a vital role in the exaggerated airway narrowing seen in asthma. However, whether asthmatic ASM is mechanically different from nonasthmatic ASM is unclear. Much of our current understanding about ASM mechanics comes from measurements made in other species. Limited data on human ASM mechanics prevents proper comparisons between healthy and asthmatic tissues, as well as human and animal tissues. In the current study, we sought to define the mechanical properties of healthy human ASM using tissue from intact lungs and compare these properties to measurements in other species. The mechanical properties measured included: maximal stress generation, force-length properties, the ability of the muscle to undergo length adaptation, the ability of the muscle to recover from an oscillatory strain, shortening velocity and maximal shortening. The ultrastructure of the cells was also examined. Healthy human ASM was found to be mechanically and ultrastructurally similar to that of other species. It is capable of undergoing length adaptation and responds to mechanical perturbation like ASM from other species. Force generation, shortening capacity and velocity were all similar to other mammalian ASM. These results suggest that human ASM shares similar contractile mechanisms with other animal species and provides an important dataset for comparisons with animal models of disease and asthmatic ASM.

Abstract
BACKGROUND The authors used results from a 20-year, high-intensity follow-up to measure the influence of ageing, and of age at onset, on the long-term persistence of symptoms in major depressive disorder (MDD). METHOD Subjects who completed a 20-year series of semi-annual and then annual assessments with a stable diagnosis of MDD or schizo-affective disorder other than mainly schizophrenic (n=220) were divided according to their ages at intake into youngest (18-29 years), middle (30-44 years) and oldest (>45 years) groups. Depressive morbidity was quantified as the proportion of weeks spent in major depressive or schizo-affective episodes. General linear models then tested for effects of time and time x group interactions on these measures. Regression analyses compared the influence of age of onset and of current age. RESULTS Analyses revealed no significant time or group x time effects on the proportions of weeks in major depressive episodes in any of the three age groups. Earlier ages of onset were associated with greater symptom persistence, particularly in the youngest group. The proportions of weeks ill showed intra-individual stability over time that was most evident in the oldest group. CONCLUSIONS These results indicate that the persistence of depressive symptoms in MDD does not change as individuals move from their third to their fifth decade, from their fourth to their sixth decade, or from their sixth to their eighth decade. An early age of onset, rather than youth per se, is associated with greater morbidity over two decades.

Abstract
BACKGROUND This analysis aimed to show whether symptoms of either pole change in their persistence as individuals move through two decades, whether such changes differ by age grouping, and whether age of onset plays an independent role in symptom persistence. METHOD Participants in the National Institute of Mental Health (NIMH) Collaborative Depression Study (CDS) who completed at least 20 years of follow-up and who met study criteria for bipolar I or schizo-affective manic disorder, before intake or during follow-up, were divided by age at intake into youngest (18-29 years, n=56), middle (30-44 years, n=68) and oldest (>44 years, n=24) groups. RESULTS The persistence of depressive symptoms increased significantly in the two younger groups. Earlier ages of onset were associated with higher depressive morbidity throughout the 20 years of follow-up but did not predict changes in symptom persistence. The proportions of weeks spent in episodes of either pole correlated across follow-up periods in all age groupings, although correlations were stronger for depressive symptoms and for shorter intervals. CONCLUSIONS Regardless of age at onset, the passage of decades in bipolar illness seems to bring an increase in the predominance of depressive symptoms in individuals in their third, fourth and fifth decades and an earlier age of onset portends a persistently greater depressive symptom burden. The degree to which either depression or manic/hypomanic symptoms persist has significant stability over lengthy periods and seems to reflect traits that manifest early in an individual's illness.

Abstract
OBJECTIVE We examined the relationship between certain bipolar I disorder clinical course variables over 5 years with outcome over the subsequent 5-year period. METHODS Prospective observational follow-up data of 123 bipolar I subjects were analyzed. Predictive clinical variables included the frequency and direction of switches, and the quantity, polarity and length of affective periods. Outcome variables were an affective burden index (ABI) accounting for week-by-week severity and weeks hospitalized. Bivariate analyses guided the selection of predictors for multivariable analyses against the outcome variables. RESULTS Affective burden index: while the number and direction of switches, the number of polyphasic episodes, weeks in hypomania/mania/mixed state, weeks in minor/major depression, weeks in at least marked affective syndrome, and weeks in any affective syndrome all had bivariate correlation (p<0.01) with the ABI, only weeks in hypomania/mania/mixed state and weeks in minor/major depression made significant contributions in the multivariable analysis (p<0.01) with the ABI. Weeks hospitalized: weeks in at least marked affective syndrome were significantly correlated with weeks hospitalized in bivariate analysis (p<0.01), and maintained a contribution to weeks hospitalized in the multivariable analysis (p<0.01). CONCLUSIONS The quantity and severity of weeks in symptomatic affective states are possibly greater predictors of affective burden in bipolar I patients than the quantity and direction of affective switches.

Abstract
OBJECTIVE To determine the pattern of birth weight of neonates in a teaching-referral hospital and to identify some epidemiological parameters associated with them. STUDY DESIGN A prospective descriptive study, using a pre-prepared Questionnaire, on all deliveries in the maternity ward during one year. SETTING The Gondar College of Medical Sciences Hospital, Gondar, north western Ethiopia. RESULTS 810 consecutive hospital births were recorded. The mean birth weight of 373 full term singleton neonates was 3 003g (SD600). The incidence of low birth weight (birth weight < 2 500 g) and very low birth weight (birth weight < 1 500 g) was 15.4% and 2.6% respectively. The mean birth weight and percentage of low birth weight were significantly different in both sexes (p < 0.0001). The birth weight increases as parity and length of gestation increase. As maternal age and maternal height increase, so do the birth weights of their neonates in this study. Total house hold income, maternal education and antenatal care use were not found to influence the mean birth weight in this study. CONCLUSION The mean birth weight and prevalence of low birth weight are similar to other reports from Ethiopia. It was observed that as maternal age, maternal height, parity and length of gestation increase, the mean birth weight increase in this study.
