The Role of a Plant-Only (Vegan) Diet in Gastroesophageal Reflux Disease: Online Survey of the Italian General Population.

The relationship between food and the pathophysiological mechanisms of gastroesophageal reflux disease (GERD) is unclear. There are few data on the impact of dietary habits on GERD symptoms and on the incidence of GERD in subjects undergoing plant-based diets. In this study, we investigated the association between diet and GERD, using data collected through an online survey of the Italian general population. In total, 1077 subjects participated in the study. GERD was defined according to the Montreal Consensus. For all subjects age, gender, body mass index (BMI), marital status, education, occupation, alcohol consumption, and smoking habits were recorded. All participants also completed the SF-36 questionnaire on Quality of Life. A total of 402 subjects (37.3%) were vegans and 675 (62.7%) non-vegans. The prevalence of GERD in the total population was 9%. Subjects with GERD-related symptoms recorded a worse quality of life according to SF-36 analysis (p < 0.05 for all dimensions). In multivariate analysis, after adjusting for confounders, participants undergoing a vegan diet had a significantly lower risk of GERD (OR = 0.47, 95% CI 0.28-0.81, p = 0.006). These findings should be taken into account to inform the lifestyle management of GERD.

Health-Related Quality of Life and Symptom-Specific Functional Impairment Among Patients Treated with Parenterally Administered Complement Inhibitors for Paroxysmal Nocturnal Hemoglobinuria

Introduction: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired, life-threatening, stem cell disorder that renders red blood cells vulnerable to complement-mediated hemolysis. This study describes the health-related quality of life (HRQoL) and symptom-specific functional impairment of patients with PNH in a real-world setting. Methods: US-based adults with PNH treated with a parenterally administered complement inhibitor (PACI) for ≥6 months completed an online, cross-sectional, observational survey; a subset of patients also participated in individual semi-structured qualitative interviews after completing the survey. The survey included the PROMIS® 29+2 Profile v2.1 (PROMIS 29+2) to measure HRQoL. The FACIT Fatigue, Neuro-QOL Item Bank v2.0 Cognitive Function Short Form, and PROMIS Item Bank v1.0 Dyspnea Functional Limitations 10a Short Form measured functional impairment associated with specific symptoms of PNH. For each patient with PNH who completed the online survey, up to 3 age- (+/- 3 years) and sex-matched adults without PNH also completed the survey. The HRQoL and functional impairment of the PNH sample was compared to that of general population (GP) sample using independent samples t-tests or Mann-Whitney tests. To further explore the experiences of patients with PNH, the association between HRQoL/functional impairment and fatigue severity was investigated. Patients with PNH were grouped according to their self-reported fatigue severity over the past 7 days (very mild or mild vs moderate, severe, or very severe [no patients reported no fatigue]). Differences in scores across these 2 groups were tested. Data from the qualitative interviews were coded using thematic analysis to explore key concepts related to HRQoL and impairment due to PNH symptoms. Data collection began in March 2023; results are based on interim data. Results: Demographic characteristics of the study samples (PNH survey sample: N=31, GP survey sample: N=62, PNH interview sample: N=10) are shown in Table 1. Patients were treated for PNH with eculizumab, pegcetacoplan, or ravulizumab, with an average duration of current PACI treatment of 3.4 years. Compared to the age and sex-matched GP sample, patients with PNH had significantly higher median scores on the PROMIS 29+2 fatigue domain (GP: 48.70 vs PNH: 57.10, p=0.041) and PROMIS Dyspnea Functional Limitations short form (GP: 40.70 vs PNH: 48.60, p=0.036), indicating that patients with PNH experience more fatigue and dyspnea limitations than the GP sample. Patients with PNH also had significantly lower median scores on the PROMIS 29+2 ability to participate in social roles/activities domain (GP: 53.50 vs PNH: 44.20, p=0.013), indicating greater role/activity limitations among patients with PNH. Compared to the GP sample, patients with PNH had numerically lower (i.e., worse) median PROMIS 29+2 cognitive functioning domain scores (GP: 50.00 vs PNH: 46.30, p=0.058) and FACIT Fatigue scores (GP: 39.50 vs PNH: 30.00, p=0.057). Within the PNH sample, statistically significant associations (p&amp;lt;0.05) were observed between fatigue severity and HRQoL/functional impairment for all outcomes except for the PROMIS 29+2 sleep disturbance and cognitive functioning domains (Table 2). Patients with more severe fatigue had worse HRQoL and more functional impairment than patients with less severe fatigue. Interview participants described fatigue-related functional impairments in their physical, social, and cognitive functioning. Fatigue made daily activities (e.g., cooking, cleaning, going for a walk) difficult and sometimes impossible. Planning social activities in advance was also challenging as patients could not predict how they would feel on any given day, and often found they had to miss, postpone, or cancel social engagements. Finally, patients described experiencing “brain fog” including difficulty concentrating, forgetfulness, and delayed cognitive processing. Conclusions: Despite receiving treatment for PNH, patients experienced deficits in areas of HRQoL related to fatigue, participation in social roles, cognitive function, and functional limitations due to dyspnea, relative to a sample of GP adults. During follow-up interviews, patients emphasized the deep and broad impacts that fatigue and cognitive functioning had, making daily activities and their social lives very difficult.

Risk factors for domestic violence during the COVID-19 pandemic-a multi-country longitudinal survey

Abstract Background A pressing public health issue exacerbated by the COVID-19 pandemic is domestic violence. The lockdowns harshened its major risk factors, such as financial strain, substance use, low social support, and also confined victims with their abusers. Cross-sectional studies confirm most of these associations, but longitudinal evidence is lacking. We investigate the association of domestic violence victimisation with these factors across the stages of the pandemic internationally and the characteristics linked with first vicitmisation in the pandemic. Methods We used four waves of an online survey of the adult general population of 14 countries in five continents in May 2020-May 2022 (N = 6051). Partner and child abuse were assessed with single items, sociodemographics and COVID-19 related data with Likert-type items, substance use and social support with validated scales. The Oxford Lockdown Stringency Index was used. Differences by onset of violence were tested with chi-squared, ANOVA and Kruskal-Wallis tests, and the associations with mixed effects logistic regression. Results Results are preliminary. Survivors with onset of violence before and during the pandemic were quite similar and differed from those not victimised in financial strain and social support. Social support (OR .83 CI .76-.91), employment status, especially unemployed (OR 5.24 CI 1.98-13.87), and polysubstance abuse (OR 2.22 CI 1.25-3.95) significantly predicted violence across time controlled for demographics. Lockdown stringency had no significant effect (OR 1.0 CI .98-1.01). Conclusions The findings are in line with the literature and clarify that the most robust financial strain proxy across time is unemployment. Pre-existing demographic, economic and health-related vulnerabilities remain impactful across countries and individuals, so screening by healthcare providers for victimisation should be targeted and policies should focus on maintaining financial stability, particularly in the long run. Key messages • The socio-economic repercussions of the COVID-19 pandemic are more impactful than confinement on the long-term risk of domestic violence internationally. • Cases of domestic violence with onset during the pandemic show similar socio-economic vulnerabilities as those with onset before.

Examining beliefs about reconciliation and social integration in Kosovo: Testing effects of interethnic contact and differences in perspective among ethnic Albanians and Serbs

AbstractAcross two studies, this research examined belief that reconciliation is necessary, belief that reconciliation is possible and belief in the value of social integration and willingness to integrate socially among Kosovar Albanians and Kosovar Serbs. Study 1 assessed these beliefs through a general population survey distributed via social media, whereas Study 2 assessed them before and after Kosovar youth participated in a program encouraging cross‐ethnic contact. Results show that these beliefs are modestly correlated and they show significant differences across ethnic groups. As the ethnic minority in Kosovo, Serbs are less likely to believe that reconciliation is possible and less willing to integrate socially than Kosovar Albanians. Moreover, across both studies, contact experience is a significant predictor of reconciliation beliefs regardless of ethnicity. Study 2 revealed that Kosovar youth can become more likely to believe that reconciliation is possible and social integration is valuable through participating in a cross‐ethnic contact program.

Comparing COVID-19 Response Behaviors between a Cancer Patient Sample and a Population-Based Cancer-Free Sample in a Rural Midwestern State

Introduction: The COVID-19 pandemic caused an increase in fear, anxiety, and depressive symptoms globally. For populations at increased risk for adverse outcomes due to illness, such as cancer patients, these worries may have been exacerbated. Understanding how the pandemic impacted cancer patients will inform better preparation for future events that cause disturbances to cancer care delivery. Methods: This study analyzed data from two surveys to determine whether cancer patients’ responses differed from a cancer-free population-based sample in terms of concerns, preventive behaviors, and thoughts on their healthcare provider’s communication regarding COVID-19 in a US Midwestern state. In August 2020, a survey was sent to 10,009 Iowans aged 18 and older, randomly selected from the 2018 Iowa voter registration file. In September 2020, a survey was emailed to 2,954 cancer patients aged 18 and older who opted into the University of Iowa Holden Comprehensive Cancer Center’s Patients Enhancing Research Collaborations at Holden program. Previously validated and pretested Likert-type and multiple-choice items assessed concern regarding COVID-19, social distancing perception and behaviors, and demographic characteristics of respondents. We used χ2 tests and logistic regression to examine differences between the cancer patient and general population survey responses. Results: We included 3,622 responses from the general population survey and 780 responses from the cancer patient survey in this analysis. Cancer patient survey respondents were more frequently older, lived in urban areas, had Medicare insurance coverage, had a college degree or higher, and were married. Cancer patients were more likely to report engaging in social distancing behaviors and greater concern regarding the pandemic. Conclusion: This study suggests differences in the impact of the COVID-19 pandemic on cancer patients compared to cancer-free members of the general population. These results indicate the need for consideration of cancer patients’ physical and mental health during large-scale disruptions to cancer care.

Age of onset and cumulative risk of mental disorders: a cross-national analysis of population surveys from 29 countries

Information on the frequency and timing of mental disorder onsets across the lifespan is of fundamental importance for public health planning. Broad, cross-national estimates of this information from coordinated general population surveys were last updated in 2007. We aimed to provide updated and improved estimates of age-of-onset distributions, lifetime prevalence, and morbid risk. In this cross-national analysis, we analysed data from respondents aged 18 years or older to the World Mental Health surveys, a coordinated series of cross-sectional, face-to-face community epidemiological surveys administered between 2001 and 2022. In the surveys, the WHO Composite International Diagnostic Interview, a fully structured psychiatric diagnostic interview, was used to assess age of onset, lifetime prevalence, and morbid risk of 13 DSM-IV mental disorders until age 75 years across surveys by sex. We did not assess ethnicity. The surveys were geographically clustered and weighted to adjust for selection probability, and standard errors of incidence rates and cumulative incidence curves were calculated using the jackknife repeated replications simulation method, taking weighting and geographical clustering of data into account. We included 156 331 respondents from 32 surveys in 29 countries, including 12 low-income and middle-income countries and 17 high-income countries, and including 85 308 (54·5%) female respondents and 71 023 (45·4%) male respondents. The lifetime prevalence of any mental disorder was 28·6% (95% CI 27·9-29·2) for male respondents and 29·8% (29·2-30·3) for female respondents. Morbid risk of any mental disorder by age 75 years was 46·4% (44·9-47·8) for male respondents and 53·1% (51·9-54·3) for female respondents. Conditional probabilities of first onset peaked at approximately age 15 years, with a median age of onset of 19 years (IQR 14-32) for male respondents and 20 years (12-36) for female respondents. The two most prevalent disorders were alcohol use disorder and major depressive disorder for male respondents and major depressive disorder and specific phobia for female respondents. By age 75 years, approximately half the population can expect to develop one or more of the 13 mental disorders considered in this Article. These disorders typically first emerge in childhood, adolescence, or young adulthood. Services should have the capacity to detect and treat common mental disorders promptly and to optimise care that suits people at these crucial parts of the life course. None.

Public Attitudes Towards Automated External Defibrillators: Results of a Survey in the Australian General Population

Public Attitudes Towards Automated External Defibrillators: Results of a Survey in the Australian General Population

Factors associated with patient activation among individuals with depression within racial/ethnic groups in the United States

Increasing patient activation may be vital for improving quality of care for individuals with depression. Among adults with depression who reside in the United States, we sought to examine the association of depression severity, race/ethnicity, and household income with patient activation and within identify factors associated with patient activation within race/ethnicity groups. Data from the 2020 US National Health and Wellness Survey, a cross-sectional, general population survey, were used to identify White, Black/African American, Asian, and Hispanic respondents with self-reported physician-diagnosed depression. Generalized linear models were used to identify factors associated with patient activation. Analyses included 8,216 respondents (mean age = 44 years, 68.0% female). Depression severity was negatively associated with patient activation (β = −0.29, p < 0.001). Patient activation was significantly higher in Black vs. White respondents (β = 1.50, p = 0.001) and in respondents with a household income of $25,000–$49,999 (β = 0.96, p = 0.015), $50,000–$99,000 (β = 0.88, p = 0.031), and ≥$100,000 (β = 1.78, p < 0.001) vs. <$25,000. Adjusted mean patient activation scores were highest among Black respondents (61.1), followed by Hispanic (60.2), White (59.6), and Asian (59.0) respondents. Neither race/ethnicity nor household income moderated the relationship between depression severity and patient activation; however, the factors most strongly associated with patient activation differed by race/ethnicity. These results indicate that the pathway to improving patient activation in individuals with depression may vary by race/ethnicity. Understanding factors associated with patient activation can help inform the design of interventions to increase patient activation in individuals with depression.

Editors' Commentary on the 2023 ESH Management of Arterial Hypertension Guidelines.

Clinical practice guidelines are ideally suited to the provision of advice on the prevention, diagnosis, evaluation, and management of high blood pressure (BP). The recently published European Society of Hypertension (ESH) 2023 ESH Guidelines for the management of arterial hypertension is the latest in a long series of high BP clinical practice guidelines. It closely resembles the 2018 European Society of Cardiology/ESH guidelines, with incremental rather than major changes. Although the ESH guidelines are primarily written for European clinicians and public health workers, there is a high degree of concordance between its recommendations and those in the other major BP guidelines. Despite the large number of national and international BP guidelines around the world, general population surveys demonstrate that BP guidelines are not being well implemented in any part of the world. The level of BP, which is the basis for diagnosis and management, continues to be poorly measured in routine clinical practice and control of hypertension remains suboptimal, even to a conservative BP target such as a systolic/diastolic BP <140/90 mm Hg. BP guidelines need to focus much more on implementation of recommendations for accurate diagnosis and strategies for improved control in those being treated for hypertension. An evolving body of implementation science can assist in meeting this goal. Given the enormous health, social, and financial burden of high BP, better diagnosis and management should be an imperative for clinicians, government, and others responsible for the provision of health care services. Hopefully, the 2023 ESH will help enable this.

Disclosure of genetic risk in the family: A survey of the Flemish general population

ObjectivesResults from genomic sequencing often have implications not just for patients but also for their relatives. To date, there are no studies in Belgium exploring whether potential relatives would want to be informed of a genetic risk in the family and their preferences on different approaches to disclosure. MethodsWe surveyed the attitudes of the Flemish general population (n = 407) towards receiving genetic information from their family members, including attitudes towards breaches in confidentiality, preferences for who communicates genetic risk and how the information is communicated, and policy approaches to nondisclosure. ResultsMost participants wanted to be informed of their genetic risk and receive genetic testing to confirm their diagnosis. Most preferred to be informed of genetic risk by a close family member, but that when given the choice between a distant family member and a clinician, most participants preferred to be contacted by a clinician. ConclusionIn Belgium there is currently no clear legal pathway for clinicians to directly initiate contact with at-risk relatives, but the responses from members of the Flemish population analyzed in this study indicate that this approach to disclosure of genetic risk deserves further consideration. Our findings indicate that the general population would support legislation allowing clinicians to inform relatives even in cases where the patient did not want to inform them. As this is not currently allowed in Belgium, policy alternatives should be considered.

Public attitudes towards automated external defibrillators: results of a survey in the Australian general population.

Swift defibrillation by lay responders using automated external defibrillators (AEDs) increases survival in out-of-hospital cardiac arrest (OHCA). This study evaluated newly designed yellow-red vs. commonly used green-white signage for AEDs and cabinets and assessed public attitudes to using AEDs during OHCA. New yellow-red signage was designed to enable easy identification of AEDs and cabinets. A prospective, cross-sectional study of the Australian public was conducted using an electronic, anonymised questionnaire between November 2021 and June 2022. The validated net promoter score investigated public engagement with the signage. Likert scales and binary comparisons evaluated preference, comfort and likelihood of using AEDs for OHCA. The yellow-red signage for AED and cabinet was preferred by 73.0% and 88%, respectively, over the green-white counterparts. Only 32% were uncomfortable with using AEDs, and only 19% indicated a low likelihood of using AEDs in OHCA. The majority of the Australian public surveyed preferred yellow-red over green-white signage for AED and cabinet and indicated comfort and likelihood of using AEDs in OHCA. Steps are necessary to standardise yellow-red signage of AED and cabinet and enable widespread availability of AEDs for public access defibrillation.

'Lifts your spirits, lifts your mind': A co-produced mixed-methods exploration of the benefits of green and blue spaces for mental wellbeing.

Mental health problems are a considerable public health issue and spending time in nature has been promoted as a way to access a range of psychological benefits leading to the development of nature-based interventions for people with severe and enduring mental health problems. Less, however, is understood about the potential benefits and efficacy of day-to-day routine access to outdoor green and blue spaces for mental health service users. Using a mixed-methods design between April and October 2021, we explored the benefits and barriers to spending time outdoors with a purposive sample of mental health service users (N = 11) using qualitative interviews and an online general population survey (N = 1791). Qualitative evidence highlighted the restorative benefits of nature and identified a number of barriers associated with fears around personal safety, social anxiety, fatigue and lack of motivation. COVID-19 had also restricted access to green and blue spaces. Having social contact and support encouraged people to spend time outdoors. In the quantitative survey, self-report and standardised measures (the Patient Health Questionnaire and the Warwick-Edinburgh Wellbeing Scale) were used to assess past and current mental wellbeing. Statistically significant differences were found between wellbeing and the use of green and blue spaces. Those with mental health problems spent time outdoors because they: felt guilty; wanted to reduce their anxiety; or rely on someone for encouragement. Those without mental health problems endorsed more positively framed reasons including relaxation, improving physical health or getting exercise. Barriers for people with mental health problems involved safety concerns, feeling anxious and having a poor self-image. These findings give insight into motivations for an outdoor activity to help inform the design of public mental health interventions. Further work is required to improve access and safety to promote the benefits of green and blue spaces for everyone. The research team included expert experienced researchers with a mental health service provider (Praxis Care) and they were involved in the development of the research idea, funding application, design, data collection, analysis, writing up and dissemination activities.

Weight loss maintenance after a digital commercial behaviorchange program (Noom Weight): Observational cross-sectional survey study.

Behavioral weight loss programs often lead to significant short-term weight loss, but long-term weight maintenance remains a challenge. Most weight maintenance data come from clinical trials, in-person programs, or general population surveys, but there is a need for better understanding of long-term weight maintenance in real-world digital programs. This observational survey study examined weight maintenance reported by individuals who had used Noom Weight, a digital commercial behavior change program, and identified factors associated with greater weight maintenance. The cross-sectional survey was completed by 840 individuals who had lost at least 10% of their body weight using Noom Weight 6-24months prior. The study found that 75% of individuals maintained at least 5% weight loss after 1year, and 49% maintained 10% weight loss. On average, 65% of initial weight loss was maintained after 1year and 57% after 2years. Habitual behaviors, such as healthy snacking and exercise, were associated with greater weight maintenance, while demographic factors were not. This study provides real-world data on the long-term weight maintenance achieved using a fully digital behavioral program. The results suggest that Noom Weight is associated with successful weight maintenance in a substantial proportion of users. Future research will use a randomized controlled trial to track weight maintenance after random assignment and at a 2year follow-up.

Comparing participation motives of professional and non-professional respondents

In times of declining response rates and over-surveying, improving our understanding of why people participate in surveys is more important than ever. Previous research showed that online panel participants have intrinsic (e.g., topic interest, altruism) and extrinsic (e.g., incentives) participation reasons. Our study expands this research by implementing an experiment using two common forms of survey measurement: ranking and rating. The experiment was fielded in a professional respondents’ sample from a German online panel ( n = 407) and in an address-based sample (mail and online) of German non-professional respondents ( n = 1,137). Besides extrinsic and intrinsic motivations, the experiment included various study design features (i.e., mode, length, data security) and the mood during the time of contact as possible reasons for participation. The results confirm previous findings regarding the motivations of online panelists but also show important differences between professional and non-professional respondents. Specifically, the main participation reasons of professionals are topic interest (intrinsic) and incentives (extrinsic), while non-professionals are primarily motivated by intrinsic reasons (topic interest and purpose of study). This notion is also supported by the Latent Class Analyses, which showed that three of the four classes for professional respondents had a high probability of naming incentives as one of their main reasons for survey participation, whereas none of the four non-professional clusters rated incentives highly. The differences between the two samples highlight that professional panel members have different motivation structures than participants in general population surveys. This may undermine generalizability, but it also provides opportunities for targeted recruitment.

Body mass index and quality of life in people living with HIV

ABSTRACT With advances in the treatment of HIV, people living with HIV (PLWH) are now expected to have a near-normal life expectancy, but challenges remain in the form of substantially poorer health-related quality of life (HRQoL) than the general population. Being overweight or obese may pose an additional burden in PLWH, but few studies have evaluated the relationship between body mass index (BMI) and HRQoL in PLWH. This study aimed to evaluate and describe the association between HRQoL and BMI among PLWH in the US. Data were obtained from the 2018 and 2019 US National Health and Wellness Survey, an online, self-reported, general population survey. Analyses included 575 PLWH who self-reported a physician diagnosis and prescription use for the treatment of HIV, as well as 1725 propensity score matched non-HIV controls. After adjusting for age, sex, race, and comorbidities, higher BMI was associated with poorer physical (β = −0.18, p = 0.005) and general (β = −0.42, p = 0.014) HRQoL among PLWH. Additionally, PLWH reported poorer mental, physical, and general HRQoL than non-HIV controls; these relationships were not moderated by BMI. The potential negative impact of higher BMI on patients’ humanistic outcomes should be considered in HIV management, including selection of treatment.

A national survey of Iranian general population to estimate a value set for the EQ-5D-5L.

The main aim of this study is to estimate a national value set of the EQ-5D-5L questionnaire for Iran. The composite time trade-off (cTTO) and discrete choice experiment (DCE) methods; and the protocol for EuroQol Portable Valuation Technology (EQ-PVT) were used to estimate the Iran national value set. 1179 face-to-face computer-assisted interviews were conducted with adults that were recruited from five Iran major cities in 2021. Generalized least squares, Tobit, heteroskedastic, logit, and hybrid models were used to analyze the data and to identify the best fitting model. According to the logical consistency of the parameters, significance levels and prediction accuracy indices of the MAE; a heteroscedastic censored Tobit hybrid model combining cTTO and DCE responses was considered as the best fitting model to estimate the final value set. The predicted values ranged from -1.19 for the worst health state (55555) to 1 for full health (11111), with 53.6% of the predicted values being negative. Mobility was the most influential dimension on health state preference values. The present study estimated a national EQ-5D-5L value set for Iranian policy makers and researchers. The value set enables the EQ-5D-5L questionnaire to use to calculate QALYs to assist the priority setting and efficient allocation of limited healthcare resources.

Association between Loneliness, Mental Health Symptoms, and Treatment Use among Emerging Adults.

Loneliness research has focused primarily on older adult populations. There is limited research on how loneliness and social support impact young people's mental health and mental health services use. This article reports an assessment of whether loneliness and social support are associated with mental health services use and mental health symptoms (psychological distress and suicidal ideation) among emerging adults. A subsample of emerging adults ages 18 to 29 (N = 307) was drawn from the 2017 Survey of Police-Public Encounters, a cross-sectional, general population survey administered to residents of New York City and Baltimore. Ordinary least squares and binary logistic regression analyses were performed to model associations between loneliness and mental health symptoms and services use outcomes. Emerging adults with higher levels of loneliness reported higher levels of distress and suicidal ideation. Having more social support, experiencing higher levels of distress, and suicidal ideation were associated with increased odds for using services. First-generation American emerging adults and Black emerging adults were less likely to use services than their U.S.-born and non-Black counterparts. The significant impact of loneliness on mental health symptoms and the effect of social support on service use highlight the importance of developing interventions to prevent and reduce loneliness over the life course.

The HIV care continuum of Guinea-Bissau; Progress towards the UNAIDS 90-90-90 targets for HIV-1 and HIV-2

ObjectiveIn the 2020 UNAIDS HIV treatment goals, 90% of people living with HIV (PLHIV) should be diagnosed, 90% of these should receive antiretroviral treatment (ART) and 90% of these should be virally suppressed. We aimed to evaluate whether Guinea-Bissau fulfills the 2020 treatment goals for both for HIV-1 and HIV-2. DesignBy combining data from a general population survey, treatment records from HIV clinics across Guinea-Bissau and a biobank from patients attending the largest HIV clinics in Bissau, we estimated each column of the 90-90-90 cascade. Method2601 participated in the survey and were used to estimate the proportion of PLHIV who knew their HIV status and the proportion of PLHIV on ART. Answers given in the survey was verified with treatment records from HIV clinics. We measured viral load from biobank materials from HIV patients and estimated the proportion of virally suppressed PLHIV. Result19.1% of PLHIV indicated to be aware of their HIV status. Of these, 48.5% received ART, and 76.4% of these were virally suppressed. For HIV-1 and HIV-1/2 the results were 21.2%, 40.9% and 75.1%. For HIV-2 the results were 15.9%, 63.6% and 80.7%. 26.9% of all HIV-1 infected in the survey were virologically suppressed, indicating that a much higher number of HIV-1 infected were aware of their status and on treatment. ConclusionGuinea-Bissau lags severely behind both the global and regional progress. Improvement in both testing and treating HIV is necessary to improve the quality of care.

Defining and measuring 'inhalant' use in population-based surveys.

The term 'inhalants' is commonly used to describe a group of drugs that are characterised by the route of administration. There are three main sub-groups of inhalants; volatile solvents, alkyl nitrites, and nitrous oxide. These drugs all have different pharmacological properties, use patterns, and potential harms; yet they are sometimes grouped together in survey instruments. This critical review aimed to present a comparative analysis of how these inhalant drugs are defined, and use measured, across a range of population-level drug use surveys. Population-level drug use surveys of youth (n=5) and general population (n=6), which measured use of at least once type of inhalant drug, were analysed as case studies. The types of inhalants surveyed were extracted, as well as definitions of these drugs, from code books or survey methods. Differing definitions were used between surveys, and included differences between countries, and between surveys intended to measure youth and general population drug use. Of the six general population surveys; five reported nitrous oxide use, five reported volatile solvent use, and four reported alkyl nitrite use. Of the five youth-specific surveys; three reported volatile solvent use, whereas only one reported on alkyl nitrite use, and one reported nitrous oxide use. There is no consistent approach used to define or measure the use of inhalant drugs, which has implications for global comparisons and understanding drug use in different populations. We conclude that the term 'inhalants' should be discontinued, due to the limited value in continuing to group very different types of drugs solely on the basis of their route of administration. Improving the epidemiology of volatile solvents, alkyl nitrites, and nitrous oxide as distinct drug types will be of benefit to harm reduction, treatment, and prevention efforts, and ensure these are targeted appropriately to population groups and context of use.
