Abstract
OBJECTIVES Given limited data on factors associated with hepatitis C virus (HCV) treatment discontinuation and failure in low- and middle-income countries, we aimed to describe patient populations treated for HCV in five countries and identify patient groups that may need additional support. DESIGN Retrospective cohort analysis using routinely collected data. SETTING Public sector HCV treatment programmes in India (Punjab), Indonesia, Myanmar, Nigeria (Nasarawa) and Vietnam. PARTICIPANTS 104 957 patients who initiated treatment in 2016-2022 (89% from Punjab). PRIMARY OUTCOMES Treatment completion and cure. RESULTS Patient characteristics and factors associated with outcomes varied across countries and facilities. Across all patients, median age was 40 years (IQR: 29-52), 30.6% were female, 7.0% reported a history of injecting drugs, 18.2% were cirrhotic and 4.9% were coinfected with HIV. 79.8% were prescribed sofosbuvir+daclastasvir. Of patients with adequate follow-up, 90.6% (89,551) completed treatment. 77.5% (69,426) of those who completed treatment also completed sustained virological testing at 12 weeks (SVR12), and of those, 92.6% (64 305) were cured. In multivariable-adjusted models, in most countries, significantly lower treatment completion was observed among patients on 24-week regimens (vs 12-week regimens) and those initiated in later years of the programme. In several countries, males, younger patients <20 years and certain groups of cirrhotic patients were less likely to complete treatment or be cured. In Punjab, treatment completion was also lower in those with a family history of HCV and people who inject drugs (PWID); in other countries, outcomes were comparable for PWID. CONCLUSION High proportions of patients completed treatment and were cured across patient groups and countries. SVR12 follow-up could be strengthened. Males, younger people and those with decompensated cirrhosis on longer regimens may require additional support to complete treatment and achieve cure. Adequate programme financing, minimal user fees and implementation of evidence-based policies will be critical to close gaps.

Abstract
Objectives To evaluate the safety and tolerability of encapsulated Tabebuia avellanedae in generally healthy women aged 18-45 with primary dysmenorrhea. Methods A single arm, open-label trial was conducted in which 1050 mg/day of encapsulated Tabebuia avellanedae (Pau d'Arco) was administered to twelve healthy women aged 18-45 for eight weeks. The primary outcome was safety and tolerability as measured by standardized adverse events scales and serial collection of laboratory markers to assess general health, prothrombin times, and the presence or absence of anemia. Secondary outcomes included pain intensity, quality of life, and pain interference measured by the Visual Analog Scale (VAS), the Patient-Reported Outcomes Measurement Information System (PROMIS) 29 survey, and the PROMIS Visual Sexual Function and Satisfaction: Interfering Factors survey, respectively. Exploratory outcomes included serum concentration of high-sensitivity C-reactive protein as a marker of systemic inflammation. Results Seventy-five percent of participants (n = 9/12) completed the study. Seventy-five percent of study participants (n = 9/12) reported an adverse event, most of which were characterized as mild, and none were determined to be a Food and Drug Administration (FDA) serious adverse event. Most laboratory markers stayed within normal limits throughout the study period with a few clinically mild abnormalities. There was a significant decrease in pain intensity compared to baseline after the first dose (p < .01), after 4 weeks of treatment (p < .01), and after 8 weeks of treatment (p < .01). Over the 8-week intervention period, pain interference, quality of life, and sexual function and satisfaction scores improved nonsignificantly and hs-CRP decreased nonsignificantly. Conclusions Tabebuia avellanedae supplementation of 1050 mg/day dose for eight weeks in generally healthy women aged 18-45 with primary dysmenorrhea was generally safe, associated with moderate tolerability, and associated with significant improvements in pain intensity scores. Future studies examining the safety and efficacy of Tabebuia avellanedae on primary dysmenorrhea are warranted.

Abstract
With political will, modest financial investment and effective technical assistance, public sector hepatitis C virus (HCV) programmes can be established in low- and middle-income countries as a first step towards elimination. Seven countries, with support from the Clinton Health Access Initiative (CHAI) and partners, have expanded access to HCV treatment by combining programme simplification with market shaping to reduce commodity prices. CHAI has supported a multipronged approach to HCV programme launch in Cambodia, India, Indonesia, Myanmar, Nigeria, Rwanda and Vietnam including pricing negotiations with suppliers, policy development, fast-track registrations of quality-assured generics, financing advocacy and strengthened service delivery. Governments are leading programme implementation, leveraging HIV programme infrastructure/financing and focusing on higher-HCV prevalence populations like people living with HIV, people who inject drugs and prisoners. This manuscript aims to describe programme structure and strategies, highlight current commodity costs and outline testing and treatment volumes across these countries. Across countries, commodity costs have fallen from >US$100 per diagnostic test and US$750-US$900 per 12-week pan-genotypic direct-acting antiviral regimen to as low as US$80 per-cure commodity package, including WHO-prequalified generic drugs (sofosbuvir + daclatasvir). As of December 2019, 5900+ healthcare workers were trained, 2 209 209 patients were screened, and 120 522 patients initiated treatment. The cure (SVR12) rate was >90%, including at lower-tier facilities. Programmes are successfully implementing simplified, decentralised public health approaches. Combined with political will and affordable pricing, these efforts can translate into commitments to achieve global targets. However, to achieve elimination, additional investment in scale-up is required.

Abstract
Access to recommended second-line treatments is limited for patients who fail initial HCV therapy in low- and middle-income countries. Alternative regimens and associated outcomes are not well understood. Through a pooled analysis of national program data in Egypt, Georgia, and Myanmar, we observed SVR rates >90% for alternative retreatment regimens.

Abstract
BACKGROUND Integration of HIV infant testing into immunization sessions is one of the strategies designed to increase coverage of early infant diagnosis. OBJECTIVE To determine the evidence on the outcomes of such integration. METHODS A systematic review of peer-reviewed and grey literature was undertaken from electronic sources such as MEDLINE, Google Scholar, websites of international agencies, past conferences and ministries of health reports published between year 2002 and 2013. Randomized controlled trials, observational and qualitative studies were searched and those meeting selection criteria were selected and relevant information extracted using structured tool. Statistical pooling was not possible owing to the heterogeneity of the study designs and outcome measures. RESULTS Of the nine articles which met the selection criteria, none used a randomized controlled design. Of these, five articles measured mother's acceptability of their infants being tested for HIV during its first pentavalent or DPT vaccination visit, and 89·5-100% accepted. Four articles reported the proportion of mothers who returned for HIV test results, ranging from 56·8% to 86·0%. Increased uptake of HIV testing following integration was confirmed by two articles. Only one study in Tanzania determined the uptake of vaccinations following integration, with urban facilities showing stable or slight increase of monthly vaccine uptake while decreases were observed across the rural sites. In two articles, stigma was perceived by service-providers and mothers as the potential risk following integration, particularly in rural settings. DISCUSSION Despite the limited number of articles, the findings in this systematic review suggest that HIV testing during immunization clinic visits is acceptable and feasible as a possible model for service delivery. However, the impact on vaccination uptake needs further study.

Abstract
BACKGROUND Alarm overload is a significant concern in the Neonatal Intensive Care Unit (NICU). Selecting a longer oxygen saturation (SpO2) averaging time will reduce the number of alarms but may mask fluctuations in oxygenation. OBJECTIVE Characterize bedside monitor alarms in the NICU and estimate the impact of longer SpO2 averaging time and alarm delay. METHODS All bedside monitor alarms were analyzed over a 12-month period in the University of Virginia NICU, using the default averaging time (8 seconds) and SpO2 alarm limits set at 88-95% for infants on supplemental oxygen. In 10 VLBW infants, SpO2 averaging time was lowered to 2 seconds for 24 hours and events of SpO2 out of the target range were estimated with 2-, 8-, or 16-second averaging time, with and without a 15-second alarm delay. RESULTS There were 3,263,590 alarms in the unit over 12 months. Low or high SpO2 alarms constituted 79% of the total, and 55% of these events lasted <15 seconds. In 10 infants we estimated that increasing SpO2 averaging time from 2 to 16 seconds would have led to 53% fewer SpO2 alarms but the mean duration of alarms would have been 2.15-fold longer. Adding a 15-second alarm delay to 2-second SpO2 averaging in this analysis decreased SpO2 alarms by 67%. CONCLUSION Longer SpO2 averaging times mask the number and severity of events of aberrant oxygenation in preterm infants without decreasing total alarm time. Incorporating an alarm delay with shorter SpO2 averaging times can reduce alarm number and duration, and allow more accurate assessment of oxygenation, which may be important for research into consequences of aberrant oxygenation in this vulnerable population.

Abstract
Adolescents are critical to efforts to end the AIDS epidemic. Few national AIDS strategies explicitly program for children in their second decade of life. Adolescents (aged 10-19 years) are therefore largely invisible in global, regional, and country HIV and AIDS reports making it difficult to assess progress in this population. We have unprecedented knowledge to guide investment towards greater impact on HIV prevention, treatment, and care in adolescents, but it has not been applied to reach those most vulnerable and optimize efficiency and scale. The cost of this is increasing AIDS-related deaths and largely unchanged levels of new HIV infections in adolescents. An AIDS-free generation will remain out of reach if the global community does not prioritize adolescents. National AIDS responses must be accountable to adolescents, invest in strengthening and monitoring protective and supportive laws and policies and access for adolescents to high impact HIV interventions.

Abstract
OBJECTIVE To determine whether integrating antiretroviral therapy (ART) into antenatal care (ANC) and maternal and child health (MCH) clinics could improve programmatic and patient outcomes. METHODS The authors systematically searched PubMed, Embase, African Index Medicus and LiLACS for randomized controlled trials, prospective cohort studies, or retrospective cohort studies comparing outcomes in ANC or MCH clinics that had and had not integrated ART. The outcomes of interest were ART coverage, ART enrolment, ART retention, mortality and transmission of human immunodeficiency virus (HIV). FINDINGS Four studies met the inclusion criteria. All were conducted in ANC clinics. Increased enrolment of pregnant women in ART was observed in ANC clinics that had integrated ART (relative risk, RR: 2.09; 95% confidence interval, CI; 1.78-2.46; I(2): 15%). Increased ART coverage was also noted in such clinics (RR: 1.37; 95% CI: 1.05-1.79; I(2): 83%). Sensitivity analyses revealed a trend for the national prevalence of HIV infection to explain the heterogeneity in the size of the effect of ART integration on ART coverage (P = 0.13). Retention in ART was similar in ANC clinics with and without ART integration. CONCLUSION Although few data were available, ART integration in ANC clinics appears to lead to higher rates of ART enrolment and ART coverage. Rates of retention in ART remain similar to those observed in referral-based models.

Abstract
There is limited published information regarding antimicrobial use (AMU) and antimicrobial resistance (AMR) in aquaculture. Our objective was to determine the opinions of aquaculture-allied professionals around the world on the frequency of AMU and AMR in common aquatic species. The study questionnaire included five sections: respondent demographics, extent of AMU in aquaculture, frequency of observations of AMR in aquaculture, AMR monitoring and surveillance and antimicrobial susceptibility testing in various jurisdictions. It was administered in English and Spanish to 604 professionals in 25 countries and with varying expertise in aquaculture. The response rate was 33% (199/604). Over half of the participants had >10 years of experience in aquaculture: 70% (140/199) were involved in fish health/clinical work and their primary experience was with salmon, tilapia, trout, shrimp (including prawn) and/or catfish. Tetracycline use was reported by 28%, 46%, 18%, 37% and 9% of respondents working with catfish, salmon, tilapia, trout and shrimp, respectively. Resistance to tetracycline in one or more species of bacteria was reported as 'frequent-to-almost always' for the same aquaculture species by 39%, 28%, 17%, 52% and 36% of respondents, respectively. 'Frequent-to-almost always' use of quinolone was reported by 70% (32/46) and 67% (8/12) of respondents from the United States and Canada, respectively, where quinolone products are not approved for aquaculture, and extra-label fluoroquinolone use is either prohibited (United States) or discouraged (Canada). Similar frequencies of quinolone use were also reported by the majority of respondents from Europe [70% (7/10)] and Asia [90% (9/10)] where labelled indications exist. This baseline information can be used to prioritize research or surveillance for AMU and AMR in aquaculture.

Abstract
Expanding access to antiretroviral therapy (ART) has both individual health benefits and potential to decrease HIV incidence. Ensuring access to HIV services is a significant human rights issue and successful programmes require adequate human rights protections and community support. However, the cost of specific human rights and community support interventions for equitable, sustainable and non-discriminatory access to ART are not well described. Human rights and community support interventions were identified using the literature and through consultations with experts. Specific costs were then determined for these health sector interventions. Population and epidemic data were provided through the Statistics South Africa 2009 national mid-year estimates. Costs of scale up of HIV prevention and treatment were taken from recently published estimates. Interventions addressed access to services, minimising stigma and discrimination against people living with HIV, confidentiality, informed consent and counselling quality. Integrated HIV programme interventions included training for counsellors, ‘Know Your Rights’ information desks, outreach campaigns for most at risk populations, and adherence support. Complementary measures included post-service interviews, human rights abuse monitoring, transportation costs, legal assistance, and funding for human rights and community support organisations. Other essential non-health sector interventions were identified but not included in the costing framework. The annual costs for the human rights and community support interventions are United States (US) $63.8 million (US $1.22 per capita), representing 1.5% of total health sector HIV programme costs. Respect for human rights and community engagement can be understood both as an obligation of expanded ART programmes and as a critically important factor in their success. Basic rights-based and community support interventions constitute only a small percentage of overall programmes costs. ART programs should consider measuring the cost and impact of human rights and community support interventions as key aspects of successful programme expansion.

Abstract
After 30 years we are still struggling to address a devastating HIV pandemic in which over 25 million people have died. In 2010, an estimated 34 million people were living with HIV, around 70% of whom live in sub-Saharan Africa. Furthermore, in 2009 there were an estimated 1.2 million new HIV-associated TB cases, and tuberculosis (TB) accounted for 24% of HIV-related deaths. By the end of 2010, 6.6 million people were taking antiretroviral therapy (ART), around 42% of those in need as defined by the 2010 World Health Organization (WHO) guidelines. Despite this achievement, around 9 million people were eligible and still in need of treatment, and new infections (approximately 2.6 million in 2010 alone) continue to add to the future caseload. This combined with the international fiscal crisis has led to a growing concern regarding weakening of the international commitment to universal access and delivery of the Millennium Development Goals by 2015. The recently launched UNAIDS/WHO Treatment 2.0 platform calls for accelerated simplification of ART, in line with a public health approach, to achieve and sustain universal access to ART, including maximizing the HIV and TB preventive benefit of ART by treating people earlier, in line with WHO 2010 normative guidance. The potential individual and public health prevention benefits of using treatment in the prevention of HIV and TB enhance the value of the universal access pledge from a life-saving initiative, to a strategic investment aimed at ending the HIV epidemic. This review analyzes the gaps and summarizes the evidence regarding ART in the prevention of HIV and TB.

Abstract
There is considerable scientific evidence supporting the use of antiretroviral therapy (ART) in prevention of human immunodeficiency virus (HIV) and tuberculosis (TB) infections. The complex nature of the HIV and TB prevention responses, resource constraints, remaining questions about cost and feasibility, and the need to use a solid evidence base to make policy decisions, and the implementation challenges to translating trial data to operational settings require a well-organised and coordinated response to research in this area. To this end, we aimed to catalogue the ongoing and planned research activities that evaluate the impact of ART plus other interventions on HIV- and/or TB-related morbidity, mortality, risk behaviour, HIV incidence and transmission. Using a limited search methodology, 50 projects were identified examining ART as prevention, representing 5 regions and 52 countries with a global distribution. There are 24 randomised controlled clinical trials with at least 12 large randomised individual or community cluster trials in resource-constrained settings that are in the planning or early implementation stages. There is considerable heterogeneity between studies in terms of methodology, interventions and geographical location. While the identified studies will undoubtedly advance our understanding of the efficacy and effectiveness of ART for prevention, some key questions may remain unanswered or only partially answered. The large number and wide variety of research projects emphasise the importance of this research issue and clearly demonstrate the potential for synergies, partnerships and coordination across funding agencies.

Abstract
Substantial changes are needed to achieve a more targeted and strategic approach to investment in the response to the HIV/AIDS epidemic that will yield long-term dividends. Until now, advocacy for resources has been done on the basis of a commodity approach that encouraged scaling up of numerous strategies in parallel, irrespective of their relative effects. We propose a strategic investment framework that is intended to support better management of national and international HIV/AIDS responses than exists with the present system. Our framework incorporates major efficiency gains through community mobilisation, synergies between programme elements, and benefits of the extension of antiretroviral therapy for prevention of HIV transmission. It proposes three categories of investment, consisting of six basic programmatic activities, interventions that create an enabling environment to achieve maximum effectiveness, and programmatic efforts in other health and development sectors related to HIV/AIDS. The yearly cost of achievement of universal access to HIV prevention, treatment, care, and support by 2015 is estimated at no less than US$22 billion. Implementation of the new investment framework would avert 12·2 million new HIV infections and 7·4 million deaths from AIDS between 2011 and 2020 compared with continuation of present approaches, and result in 29·4 million life-years gained. The framework is cost effective at $1060 per life-year gained, and the additional investment proposed would be largely offset from savings in treatment costs alone.

Abstract
OBJECTIVE This study investigated the relation between psychotropic medication use and adverse cardiovascular (CV) events in women with symptoms of myocardial ischaemia undergoing coronary angiography. METHOD Women enrolled in the Women's Ischemia Syndrome Evaluation (WISE) were classified into one of four groups according to their reported antidepressant and anxiolytic medication usage at study intake: (1) no medication (n = 352); (2) anxiolytics only (n = 67); (3) antidepressants only (n = 58); and (4) combined antidepressant and anxiolytics (n = 39). Participants were followed prospectively for the development of adverse CV events (for example, hospitalisations for non-fatal myocardial infarction, stroke, congestive heart failure and unstable angina) or all-cause mortality over a median of 5.9 years. RESULTS Use of antidepressant medication was associated with subsequent CV events (HR 2.16, 95% CI 1.21 to 3.93) and death (HR 2.15, 95% CI 1.16 to 3.98) but baseline anxiolytic use alone did not predict subsequent CV events and death. In a final regression model that included demographics, depression and anxiety symptoms, and risk factors for cardiovascular disease, women in the combined medication group (that is, antidepressants and anxiolytics) had higher risk for CV events (HR 3.98, CI 1.74 to 9.10, p = 0.001 and all-cause mortality (HR 4.70, CI 1.7 to 2.97, p = 0.003) compared to those using neither medication. Kaplan-Meier survival curves indicated that there was a significant difference in mortality among the four medication groups (p = 0.001). CONCLUSIONS These data suggest that factors related to psychotropic medication such as depression refractory to treatment, or medication use itself, are associated with adverse CV events in women with suspected myocardial ischaemia.

Abstract
BACKGROUND Identifying which patients presenting with undifferentiated chest pain are at risk of major cardiac events is a major clinical challenge. Clinical evaluation may lack sufficient precision, leading to unnecessary admission or inappropriate discharge. It is uncertain whether risk scores derived from ACS populations apply to unselected patients with chest pain. AIM To determine the predictive accuracies of the GRACE risk score, the TIMI risk score and clinical evaluation in unselected patients with suspected cardiac pain. DESIGN Prospective observational study. METHODS We recruited 347 sequential patients with suspected cardiac pain presenting to a large teaching hospital. The main outcome measures were death, non-fatal myocardial infarction and emergency revascularization, in hospital and at 3 months. Receiver operating characteristic (ROC) curves were plotted for TIMI and GRACE risk scores and clinical evaluation. RESULTS Overall 54 patients (15.6%) experienced a major cardiac event (16 deaths, seven myocardial infarctions (MIs), one emergency revascularization) or emergency re-admission (n=30) within 3 months. Both GRACE (p<0.001) and TIMI scores (p<0.001) predicted death/MI/revascularization (and the composite including re-admission), but the GRACE score was superior to the TIMI score for predicting major cardiac events (z=2.05), and both scores were superior to clinical evaluation (ROC areas 0.82, 0.74 and 0.55 respectively). The GRACE score predicted an ACS discharge diagnosis (p<0.001) and duration of hospital stay (p<0.001). DISCUSSION In unselected patients presenting with suspected cardiac pain, the GRACE risk score is superior to the TIMI risk score in predicting major cardiac events, and both risk scores are superior to using ECG and troponin findings at presentation.

Abstract
By providing unlimited imaging planes, multiplane transesophageal echocardiography (MTEE) should improve real-time guidance of interventional procedures. The potential advantages of MTEE in this scenario have not been systematically evaluated. We retrospectively reviewed our experience with MTEE-guided Amplatzer device closure of atrial septal defects (ASDs) MTEE angles used to obtain images for guiding all measurements and maneuvers were recorded. These angles were compared to the range of MTEE angles that are postulated to be available from biplane TEE. Images obtained using MTEE angles from 21 degrees to 70 degrees and from 111 degrees to l59 degrees were defined as only obtainable by MTEE. The MTEE probe was successfully introduced in all (89) patients. Thirteen patients (15%) had multiple defects. Ninety-five devices (5-32 mm in diameter) were deployed. In 66% of patients, balloon sizing and device deployment necessitated imaging planes that are only obtainable by MTEE. All devices were well positioned, with no impingement on inflows or outflows. At follow-up, 79 of 89 (88.7%) patients had no residual ASDs. Each of the remaining 10 patients (11.3%) had a small (<3 mm) residual defect. MTEE played an important role in guiding device closure of ASD, particularly during the phases of balloon sizing and device deployment.

Abstract
An assay based on fluorescence resonance energy transfer (FRET) has been developed to screen for ubiquitination inhibitors. The assay measures the transfer of ubiquitin from Ubc4 to HECT protein Rsc 1083. Secondary reagents (streptavidin and antibody to glutathione-S-transferase [GST]), pre-labeled with fluorophores (europium chelate, Eu(3+), and allophycocyanin [APC]), are noncovalently attached via tags (biotin and GST) to the reactants (ubiquitin and Rsc). When Rsc is ubiquitinated, Eu(3+) and APC are brought into close proximity, permitting energy transfer between the two fluorescent labels. FRET was measured as time-resolved fluorescence at the emission wavelength of APC, almost entirely free of nonspecific fluorescence from Eu(3+) and APC. The FRET assay generated a lower ratio of signal to background (8 vs. 31) than an assay for the same ubiquitination step that was developed as a dissociation-enhanced lanthanide fluoroimmunoassay (DELFIA). However, compared to the DELFIA method, use of FRET resulted in higher precision (4% vs. 11% intraplate coefficient of variation). Quenching of fluorescence was minimal when compounds were screened at 10 microg/ml using FRET. Employing a quick and simple homogeneous method, the FRET assay for ubiquitin transfer is ideally suited for high throughput screening.

Abstract
OBJECTIVE To compare the levels of the 9G4 idiotope (9G4 Id) in systemic lupus erythematosus (SLE) patients with a detailed disease activity index, the British Isles Lupus Assessment Group (BILAG) index, and serological parameters of disease activity by ds DNA antibody levels and serum C3 concentrations. METHODS In a cross sectional analysis serum samples from 190 patients with SLE were studied and a further 55 serial bleeds from 14 patients. An enzyme linked immunosorbent assay was used to measure the 9G4 Id, and anti dsDNA and antimyeloperoxidase (MPO) antibodies. The C3 levels were measured by laser nephelometer. RESULTS Seventy six of 190 (40%) of the patients tested had raised 9G4 Id levels. In the cross sectional study 9G4 Id levels were found to correlate with disease activity in the BILAG cardiovascular/respiratory renal, and haematological systems and with global BILAG score (p < 0.01). In the serial bleeds 9G4 Id levels correlated with anti-dsDNA antibody and C3 levels, but not with anti-MPO antibodies. No correlations were found with treatment. In six cases the 9G4 Id levels correlated well with global BILAG scores and dsDNA antibody levels. In four cases the BILAG global and 9G4 Id levels alone correlated well. CONCLUSIONS Raised levels of the 9G4 Id are present in a substantial proportion of serum samples from patients with lupus, correlate with various aspects of disease activity in SLE. The Id is detectable on anti-dsDNA antibodies, though it must also be present on other immunoglobulins whose specificities remain unknown.

Abstract
The rapid pace of the computer revolution may well be slowed by the lack of suitable software. Though computers should be increasing business efficiency and productivity, many companies do not have the software that would enable them to enjoy these benefits. Packaged software can close the gap for both large and small companies. Here are some guidelines for making the decision whether to buy a package and for avoiding trouble once the package is installed. The article also describes the features a company should look for in packaged software and the optimal provisions of a software contract.
