- INTRODUCTION: The role of microbial translocation (MT) in HIV patients living with HIV from low- and middle-income countries (LMICs) is not fully known. The aim of this study is to investigate and compare the patterns of MT in patients from Vietnam, Ethiopia and Sweden.METHODS: Cross-sectional samples were obtained from treatment-naïve patients living with HIV-1 and healthy controls from Vietnam (n=83; n=46), Ethiopia (n=9492; n=50) and Sweden (n=51; n=19). Longitudinal samples were obtained from a subset of the Vietnamese (n=24) in whom antiretroviral therapy (ART) and tuberculostatics were given. Plasma lipopolysaccharide (LPS), sCD14 and anti-flagellin IgG were determined by the endpoint chromogenic Limulus Amebocyte Assay and enzyme-linked immunosorbent assay.RESULTS: All three biomarkers were significantly increased in patients living with HIV-1 from all countries as compared to controls. No differences were found between males and females. Vietnamese and Ethiopian patients had significantly higher levels of anti-flagellin IgG and LPS, as compared to Swedes. ART reduced these levels for the Vietnamese. Vietnamese patients given tuberculostatics at initiation of ART had significantly lower levels of anti-flagellin IgG and higher sCD14. The biomarkers were lower in Vietnamese who did not develop opportunistic infection.CONCLUSIONS: Higher MT is common in patients living with HIV compared to healthy individuals, and in patients from LMICs compared to patients from a high-income country. Treatment with tuberculostatics decreased MT while higher levels of MT are associated with a poorer clinical outcome.

- The agrarian population in low- and middle-income countries suffers from a number of adverse health effects due to pesticide exposure. In Zanzibar, the government subsidizes pesticides to enhance local rice production. The objectives of this study were to assess Zanzibar smallholder rice farmers' pesticide use and self-reported health symptoms in relation to pesticide exposure, training, and use of protective measures and to raise awareness for future local policy formulation. An exploratory cross-sectional interviewer-administered study was conducted among 99 rice farmers. Participants were selected based on convenience sampling and stratified by expected exposure category. The study participants reported using pesticides in World Health Organization (WHO) Class II. Of pesticide users, 61% reported one or more symptoms of possible acute pesticide poisoning. Only 50% of pesticide users had received training in safe handling and application of pesticides, but those who had displayed a higher use of protective measures. Farmers who did not use protective measures were more likely to have reported skin irritation and headache, which, together with eye irritation, were the most commonly reported acute symptoms. The main sociodemographic differences between the expected exposure categories of pesticide users and nonusers were in gender and education level. Scaling up of training in safe handling and application of pesticides is needed. Further studies are required to better understand the mechanisms behind the choice to use pesticides or not.

- The impact of low levels of HIV RNA (low-level viremia; LLV) during combination antiretroviral therapy (cART) on clinical outcomes is unclear. We explored the associations between LLV and all-cause mortality, AIDS, and serious non-AIDS events (SNAE).We grouped individuals starting cART 1996-2017 (identified from the Swedish InfCare HIV register) as virologic suppression (VS; <50 copies/mL), LLV (repeated viral load 50-999 copies/mL), and non-suppressed viremia (NSV; ≥1000 copies/mL). Separately, LLV was subdivided into 50-199 and 200-999 copies/mL (reflecting different definitions of virologic failure). Proportional-hazard models (including sex, age, pre-ART CD4 count and viral load, country of birth, injection drug use, treatment experience and interruptions, and an interaction term between viremia and time) were fitted for the study outcomes.6,956 participants were followed for a median of 5.7 years. At the end of follow-up, 60% were categorized as VS, 9% as LLV, and 31% as NSV. Compared with VS, LLV was associated with increased mortality (adjusted hazard ratio [aHR] 2.2, 95% confidence interval [CI] 1.3-3.6). This association was also observed for LLV 50-199 copies/mL (aHR 2.2, 95% CI 1.3-3.8), but was not statistically significant for LLV 200-999 copies/mL (aHR 2.1, 95% CI 0.96-4.7). LLV 50-999 copies/mL was not linked to increased risk of AIDS or SNAE, but in subanalysis, LLV 200-999 copies/mL was associated with SNAE (aHR 2.0, 95% CI 1.2-3.6).In this population-based cohort, LLV during cART was associated with adverse clinical outcomes.

- OBJECTIVE: To investigate the association between HIV viremia exposure during antiretroviral therapy (ART) and cardiovascular disease (CVD) risk.DESIGN: Nationwide observational cohort.METHODS: Participants (age > 15 years) from the Swedish nationwide InfCareHIV register initiating ART 1996-2017 were categorized in a time-updated manner into four viremia categories, starting from 12 months after ART initiation: suppression (<50 copies/ml), low-level viremia (50-199 copies/ml and 200-999 copies/ml, respectively), and high-level viremia (≥1000 copies/ml). In addition, cumulative viremia was estimated as the area under the log viral load (VL) curve. Proportional subhazard models adjusted for sex, age, pre-ART CD4 and VL, injection drug use, and country of birth were used to analyze the association between viremia exposure and CVD risk (ischemic heart disease, stroke, and heart failure; data obtained by linkage to national registers), accounting for the competing risk of non-CVD death.RESULTS: In all, 337 cases of CVD were observed during 44 937 person-years of follow-up (n = 6562). Higher viremia exposure was associated with CVD, both when parameterized as cumulative viremia (adjusted subhazard ratio [aSHR] per 1 log10 copy × year/ml, 1.03; 95% confidence interval [CI], 1.01-1.05) and as viremia category (aSHR for high-level viremia versus suppression, 1.45; 95% CI, 1.03-2.05). We observed no association between CVD and low-level viremia compared with those with suppression.CONCLUSIONS: Higher exposure to HIV viremia was linked to CVD in ART recipients, whereas no increased risk was detected for people with low-level viremia compared with viral suppression. Causal inference is limited by the observational nature of this study.

Tidskriftsartikel (refereegranskat)abstract
- Human immunodeficiency virus (HIV) viremia could be involved in the increased risk of cancer in people with HIV (PWH) receiving combination antiretroviral therapy (cART). We analyzed the association between plasma HIV ribonucleic acid levels in PWH starting cART and incident invasive cancer using the Swedish cohort InfCare HIV linked with national registers.Adults starting cART in 1996-2017 were included if they had ≥1 viral load (VL) measurement before receiving any antiretroviral agent (pre-ART VL) and ≥2 VLs ≥6 months after start of cART. Viremia during cART was analyzed both as viremia-copy-years and categorized as suppression (<50 copies/mL), low-level viremia ([LLV] 50-999 copies/mL), and nonsuppression (≥1000 copies/mL). The main outcome was a composite of invasive malignancies with increased incidence among PWH. We fitted proportional subhazard models (including sex, age, pre-ART CD4 count, and injection drug use) for both pre-ART VL and viremia during cART.After 32 105 person-years, 3254 of 4931 participants (66%) were classified as suppressed, 438 (9%) were classified as LLV, and 1221 (25%) were classified as nonsuppressed. Neither viremia category nor cumulative viremia during cART had a statistically significant association with cancer. Higher pre-ART VL was associated with cancer (adjusted subhazard ratio, 1.4; 95% confidence interval, 1.0-1.8); this remained statistically significant with viremia during cART in the model. In subanalysis, the association with pre-ART VL was statistically significant for acquired immune deficiency syndrome (AIDS)-defining and infection-related non-AIDS-defining cancer, but not for other malignancies.In this nationwide cohort, pre-ART VL was an independent predictor of invasive cancer, whereas viremia profile during cART was not associated with cancer incidence.

Virologic failure following low-level viremia and viral blips during antiretroviral therapy: results from a European multicenter cohort
- 2023
-
Ingår i: Clinical infectious diseases : an official publication of the Infectious Diseases Society of America. - : Oxford University Press (OUP). - 1537-6591. ; 76:1
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: It is unclear whether low-level viremia (LLV), defined as repeatedly detectable viral load (VL) of <200 copies/mL, and/or transient viremic episodes (blips) during antiretroviral therapy (ART), predict future virologic failure. We investigated the association between LLV, blips, and virologic failure (VF) in a multi-center European cohort.METHODS: People with HIV-1 who started ART 2005 or later were identified from the EuResist Integrated Database. We analyzed the incidence of VF (≥200 copies/mL) depending on viremia exposure, starting 12 months after ART initiation (grouped as suppression [≤50 copies/mL], blips [isolated VL of 51-999 copies/mL], and LLV [repeated VLs of 51-199 copies/mL]) using Cox proportional hazard models adjusted for age, sex, injecting drug use, pre-ART VL, CD4 count, HIV-1 subtype, type of ART, and treatment experience. We queried the database for drug resistance mutations (DRM) related to episodes of LLV and VF and compared those with baseline resistance data.RESULTS: During 81,837 person-years of follow-up, we observed 1,424 events of VF in 22,523 participants. Both blips (adjusted subhazard ratio [aHR], 1.7; 95% confidence interval [CI], 1.3-2.2) and LLV (aHR, 2.2; 95% CI, 1.6-3.0) were associated with VF, compared with virologic suppression. These associations remained statistically significant in sub-analyses restricted to people with VL <200 copies/mL and those starting ART 2014 or later. Among people with LLV and genotype data available within 90 days following LLV, 49/140 (35%) had at least one DRM.CONCLUSIONS: Both blips and LLV during ART are associated with increased risk of subsequent VF.

Monophylogenetic HIV-1C epidemic in Ethiopia is dominated by CCR5-tropic viruses-an analysis of a prospective country-wide cohort
- 2017
-
Ingår i: BMC Infectious Diseases. - London, United Kingdom : BioMed Central. - 1471-2334. ; 17:1

Tidskriftsartikel (refereegranskat)abstract
- Background: CCR5 coreceptor using HIV-1 subtype C (HIV-1C) has been reported to dominate the Ethiopian epidemic. However, almost all data have been obtained from two large cities in the central and north-west regions and recent data is lacking.Methods: Plasma were obtained from 420 treatment-naïve patients recruited 2009-2011 to a large country-wide Ethiopian cohort. The V3 region was sequenced and the co-receptor tropism was predicted by the clinical and clonal models of the geno2pheno tool at different false positive rates (fpr) and for subtype. In an intention to treat analysis the impact of baseline tropism on outcome of antiretroviral therapy was evaluated.Results: V3 loop sequencing was successful in 352 (84%) patients. HIV-1C was found in 350 (99.4%) and HIV-1A in two (0.6%) patients. When comparing the geno2pheno fpr10% clonal and clinical models, 24.4% predictions were discordant. X4-virus was predicted in 17.0 and 19.0%, respectively, but the predictions were concordant in only 6%. At fpr5%, concordant X4-virus predictions were obtained in 3.1%. The proportion of X4-tropic virus (clonal fpr10%) increased from 5.6 to 17.3% (p < 0.001) when 387 Ethiopian V3 loop sequences dated from 1984 to 2003 were compared with ours. In an intention to treat analysis, 67.9% reached treatment success at month 6 and only 50% at month 12. Only age and not tropism predicted therapy outcome and no difference was found in CD4+ cell gain between R5-tropic and X4-tropic infected patients. At viral failure, R5 to X4 switch was rare while X4 to R5 switch occurred more frequently (month 6: p = 0.006; month 12: p = 0.078).Conclusion: The HIV-1C epidemic is monophylogenetic in all regions of Ethiopia and R5-tropic virus dominates, even in patients with advanced immunodeficiency, although the proportion of X4-tropic virus seems to have increased over the last two decades. Geno2pheno clinical and clonal prediction models show a large discrepancy at fpr10%, but not at fpr5%. Hence further studies are needed to assess the utility of genotypic tropism testing in HIV-1C. In ITT analysis only age and not tropism influenced the outcome.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: Patients' perception of the quality and patient-centredness of healthcare has gained increasing interest in the last decade in Sweden, as in other countries. The purpose of the study was to evaluate to what extent patients perceived Swedish healthcare as patient-centred and to explore the satisfaction levels related to gender, education level and to having or not having Swedish as one's mother tongue. Design and settings: This study has a cross-sectional design. Analyses were based on the first national patient surveys in Sweden, conducted between 2009 and 2010. The surveys included responses from 232 518 patients who had been in contact with primary, outpatient, inpatient, or emergency care units. Survey questions related to indicators of patient-centred care and sociodemographic variables were selected for the analysis. The patients' level of satisfaction in the selected indicators was analysed and compared by sociodemographic and background factors. Multivariable logistic regression models were used for analysis. Results: The patients expressed high levels of satisfaction in questions related to the 'Respect' indicator (81-96% satisfied) but lower levels in most of the other indicators of patient-centred care. Only 25-30% of the patients reported they had been told about possible warning signs of their condition or treatment and 58-66% said they had received enough information about their condition. Group differences were detected. The most satisfied patient groups were men, individuals with low levels of education and those with Swedish as their mother tongue. Conclusions: According to these first national patient surveys, achieving patient-centred healthcare for all citizens is a challenge for Swedish healthcare authorities. Future analyses of national patient surveys should show whether national efforts to encourage acceptance of patient-centred approaches and strategies for equal care will give intended results.

- Objectives To explore the healthcare-seeking pathways, antibiotic prescribing and determine the sociodemographic factors associated with healthcare-seeking behaviour (HSB) of caregivers for common illnesses in under-5 (U-5) children in rural Ujjain, India.Study design Prospective cohort study.Study setting and study sample The cohort included 270 U-5 children from selected six villages in rural demographic surveillance site, of the R.D. Gardi Medical College, Ujjain, Madhya Pradesh, India. A community-based cohort was visited two times weekly for over 113 weeks (August 2014 to October 2016) to record the HSB of caregivers using HSB diaries. Sociodemographic information was also solicited.Primary and secondary outcome measures Primary outcomes: first point of care, healthcare-seeking pathway and quantify antibiotic prescribing for the common acute illnesses.Secondary outcome HSB risk factors were determined using mixed-effects multinomial logistic regression.Results A total of 60 228 HSB follow-up time points for 270 children were recorded with a total of 2161 acute illness episodes. The most common illnesses found were respiratory tract infections (RTI) (69%) and gastrointestinal tract infections (8%). No healthcare was sought in 33% of illness episodes, mostly for RTIs. The most common healthcare-seeking pathway was to informal healthcare providers (IHCPs, 49% of illness episodes). The adjusted relative risk for obtaining no treatment, home treatment and treatment by IHCPs was higher for RTIs (aRR=11.54, 1.82 and 1.29, respectively), illiterate mothers (aRR=2.86, 2.38 and 1.93, respectively), and mothers who were homemakers (aRR=2.90, 4.17 and 2.10, respectively). Socioeconomic status was associated with HSB, with the highest aRR for no treatment in the lowest two socioeconomic quintiles (aRR=6.59 and 6.39, respectively). Antibiotics were prescribed in 46% (n=670/1450) illness episodes and the majority (85%, n=572/670) were broad spectrum.Conclusion In our rural cohort for many acute episodes of illnesses, no treatment or home treatment was done, which resulted in overall reduced antibiotic prescribing. The most common healthcare-seeking pathway was to visit IHCPs, which indicates that they are major healthcare providers in rural areas. Most of the antibiotics were prescribed by IHCPs and were commonly prescribed for illnesses where they were not indicated.

Tidskriftsartikel (refereegranskat)abstract
- People living with HIV (PLHIV) have an increased risk of hematologic malignancies (HMs). We aimed to characterize HMs among PLHIV at Karolinska University Hospital, Stockholm, Sweden. We studied all PLHIV receiving care at our center between 2004 and 2018. Data were retrieved retrospectively from InfCareHIV database and medical records. Around 3,484 patients received HIV care for a total of 22,903 person-years (py) with median follow-up of 7.6 years. HMs were identified in 43 patients with 30 cases of non-Hodgkin lymphoma (NHL), 9 cases of Hodgkin lymphoma (HL), 2 multicentric Castleman's disease, and 1 case each of myeloma and myelodysplastic syndrome. The incidence rate of NHL was 88/10(5) py and HL 39.6/10(5) py. The incidence of NHL declined 2004-2010 versus 2011-2018 (180.8 vs. 40.1/10(5) py; p = .001). Median time from HIV diagnosis to malignancy was shorter in NHL compared with HL (1.2 years vs. 8.9 years; p = .01) and effective HIV treatment was less common in NHL (33% vs. 100%; p < .001). The 5-year survival rate of NHL was 59% and HL 43%, significantly lower compared with lymphoma survival in the general population in Sweden. In the era of effective antiretroviral therapy (ART), the incidence rate of lymphoma was more than five times higher in PLHIV and 5-year survival significantly inferior. Efforts for earlier identification of HIV-infected individuals are likely to affect the incidence of NHL. Additionally, an effective screening for clinical and laboratory signs of HL in PLHIV on ART should be introduced to improve identification and survival of HL in this population.

Tidskriftsartikel (refereegranskat)abstract
- Background:Over 50% of people living with HIV (PLHIV) in sub-Saharan Africa are lost to follow-up between diagnosis and initiation of antiretroviral treatment during pre-antiretroviral (pre-ARV) care. The effect of providing home counseling visits by community support agents on 2-year retention in pre-ARV care was evaluated through a randomized controlled trial in eastern Uganda.Methods:Four hundred newly screened HIV-positive patients were randomly assigned to receive posttest counseling alone (routine arm) or posttest counseling and monthly home counseling visits by community support agents to encourage them go back for routine pre-ARV care (intervention arm). The outcome measure was the proportion of new PLHIV in either arm who attended their scheduled pre-ARV care visits for at least 6 of the anticipated 8 visits in the first 24 months after HIV diagnosis. The difference between the 2 study arms was assessed using the (2) and T tests. Mantel-Haenszel Risk Ratios and multivariate logistic models were used to assess the adjusted effect of the intervention on the outcome.Results:In all models generated, participants receiving monthly home counseling visits were 2.5 times more likely to be retained in pre-ARV compared with those in standard care over a period of 24 months (adjusted risk ratio, 2.5; 95% confidence interval: 2.0 to 3.0).Conclusion:Monthly follow-up home visits by community workers more than doubled the retention of PLHIV in pre-ARV care in rural Uganda and can be applicable in similar resource-poor settings.

Tidskriftsartikel (refereegranskat)abstract
- In this cross-sectional study we present an integrated analysis of a self-reported Health Questionnaire and socio-demographic and treatment outcome data from the national Swedish HIV cohort, InfCareHIV.To evaluate the Health Questionnaire and identify the main determinants of adherence.A total of 2,846 patients answered a nine-item disease-specific Health Questionnaire between 2012 and 2014, corresponding to 44% of all active patients in the national InfCareHIV cohort. The questionnaire assessed patient related outcome measures (PROMs) regarding health and antiretroviral treatment (ART) and patient related experience measures (PREMs) regarding involvement in care and satisfaction with the care provider.We found the Health Questionnaire to be valid and reliable when used in ordinary clinical practice. There was a high concordance between self-reported adherence to ART in the past seven days and treatment outcome, with 94% of patients who reported optimal adherence having a viral load <50 copies/ml. The main determinants of optimal adherence were heterosexual transmission path, being born in Sweden, being male, not reporting experience of ART side effects and being fully satisfied with care.The nine-item Health Questionnaire can identify patients at risk of treatment failure, those in need of clinical assessment of adverse events and those with impaired physical health.

A Single-Blind randomized controlled trial to evaluate the effect of extended counseling on uptake of pre-antiretroviral care in Eastern Uganda
- 2011
-
Ingår i: Trials. - : Springer Science and Business Media LLC. - 1745-6215. ; 12, s. 184-
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Many newly screened people living with HIV (PLHIV) in Sub-Saharan Africa do not understand the importance of regular pre-antiretroviral (ARV) care because most of them have been counseled by staff who lack basic counseling skills. This results in low uptake of pre-ARV care and late treatment initiation in resource-poor settings. The effect of providing post-test counseling by staff equipped with basic counseling skills, combined with home visits by community support agents on uptake of pre-ARV care for newly diagnosed PLHIV was evaluated through a randomized intervention trial in Uganda. Methods: An intervention trial was performed consisting of post-test counseling by trained counselors, combined with monthly home visits by community support agents for continued counseling to newly screened PLHIV in Iganga district, Uganda between July 2009 and June 2010, Participants (N = 400) from three public recruitment centres were randomized to receive either the intervention, or the standard care (the existing post-test counseling by ARV clinic staff who lack basic training in counseling skills), the control arm. The outcome measure was the proportion of newly screened and counseled PLHIV in either arm who had been to their nearest health center for clinical check-up in the subsequent three months +2 months. Treatment was randomly assigned using computer-generated random numbers. The statistical significance of differences between the two study arms was assessed using chi-square and t-tests for categorical and quantitative data respectively. Risk ratios and 95% confidence intervals were used to assess the effect of the intervention. Results: Participants in the intervention arm were 80% more likely to accept (take up) pre-ARV care compared to those in the control arm (RR 1.8, 95% CI 1.4-2.1). No adverse events were reported. Conclusions: Provision of post-test counseling by staff trained in basic counseling skills, combined with home visits by community support agents had a significant effect on uptake of pre-ARV care and appears to be a cost-effective way to increase the prerequisites for timely ARV initiation.

Lack of pre-antiretroviral care and competition from traditional healers, crucial risk factors for very late initiation of antiretroviral therapy for HIV : A case-control study from eastern Uganda
- 2011
-
Ingår i: Pan African Medical Journal. - : Pan African Medical Journal. - 1937-8688. ; 8:40
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND:Although WHO recommends starting antiretroviral treatment at a CD4 count of 350 cells/[µ]L, many Ugandan districts still struggle with large proportions of clients initiating ART very late at CD4 < 50 cells/[µ]L. This study seeks to establish crucial risk factors for very late ART initiation in eastern Uganda.METHODS:All adult HIV-infected clients on ART in Iganga who enrolled between 2005 and 2009 were eligible for this case-control study. Clients who started ART at CD4 cell count of < 50 cells/[µ]L (very late initiators) were classified as cases and 50-200 cells/[µ]L (late initiators) as control subjects. A total of 152 cases and 202 controls were interviewed. Multivariate analyses were performed to calculate adjusted odds ratios and 95% confidence intervals.RESULTS:Reported health system-related factors associated with very late ART initiation were stock-outs of antiretroviral drugs stock-outs (affecting 70% of the cases and none of the controls), competition from traditional/spiritual healers (AOR 7.8, 95 CI% 3.7-16.4), and lack of pre-ARV care (AOR 4.6, 95% CI: 2.3-9.3). Men were 60% more likely and subsistence farmers six times more likely (AOR 6.3, 95% CI: 3.1-13.0) to initiate ART very late. Lack of family support tripled the risk of initiating ART very late (AOR 3.3, 95% CI: 1.6-6.6).CONCLUSION:Policy makers should prevent ARV stock-outs though effective ARV procurement and supply chain management. New HIV clients should seek pre-ARV care for routine monitoring and determination of ART eligibility. ART services should be more affordable, accessible and user-friendly to make them more attractive than traditional healers.

- An estimated 350 million cases of STIs occur globally each year. In Sweden, Chlamydia is the most common STI with approximately 30 000 cases annually, disproportionally affecting youth. National surveys report low condom use among youth. Smartphone coverage is high among this tech-savvy group. In collaboration with youth, we developed an interactive smartphone application comprising games, peer experiences and information snippets to promote condom use.Objectives: To evaluate in a randomised controlled trial, the effectiveness of this smartphone application to improve condom use among youth in Stockholm, Sweden.Methods: This two-arm, individually randomised controlled trial was implemented through the Youth Health Clinics (YHC) in Stockholm, Sweden. Youth aged 18–23 years, who owned a smartphone and had ≥2 sexual partners during the past 6 months were eligible. The intervention delivered the interactive elements described above over 180 days. The control group received a ‘dummy’ application. Both groups received standard of care at the YHC. The primary outcome was proportion of consistent (100%) self-reported condom use at 6 months. Secondary outcomes included self-reported number of partners, occurrence of STIs/pregnancy and STI tests during the study period. An intention-to-treat approach was used.Results: 214 and 219 youth were randomised to the intervention and control groups, respectively. Consistent condom use was reported for 32/214 (15.0%) in the intervention group and for 35/219 (16.0%) in the control group (OR 0.9, 95% CI 0.5 to 1.6). No significant differences in secondary outcomes were seen.Conclusion: We were unable to detect an effect of the intervention. Future research should focus on targeting different subgroups within the overall risk group, with tailored mHealth interventions. The potential for such interventions in settings where sexual health services are unavailable should be evaluated.Trial registration number: ISRCTN13212899.

- Background: Genital Chlamydia trachomatis infection is a major public health problem worldwide affecting mostly youth. Sweden introduced an opportunistic screening approach in 1982 accompanied by treatment, partner notification and case reporting. After an initial decline in infection rate till the mid-90s, the number of reported cases has increased over the last two decades and has now stabilized at a high level of 37,000 reported cases in Sweden per year (85% of cases in youth). Sexual risk-taking among youth is also reported to have significantly increased over the last 20 years. Mobile health (mHealth) interventions could be particularly suitable for youth and sexual health promotion as the intervention is delivered in a familiar and discrete way to a tech savvy at-risk population. This paper presents a protocol for a randomized trial to study the effect of an interactive mHealth application (app) on condom use among the youth of Stockholm. Methods: 446 youth resident in Stockholm, will be recruited in this two arm parallel group individually randomized trial. Recruitment will be from Youth Health Clinics or via the trial website. Participants will be randomized to receive either the intervention (which comprises an interactive app on safe sexual health that will be installed on their smart phones) or a control group (standard of care). Youth will be followed up for 6 months, with questionnaire responses submitted periodically via the app. Self-reported condom use over 6 months will be the primary outcome. Secondary outcomes will include presence of an infection, Chlamydia tests during the study period and proxy markers of safe sex. Analysis is by intention to treat. Discussion: This trial exploits the high mobile phone usage among youth to provide a phone app intervention in the area of sexual health. If successful, the results will have implications for health service delivery and health promotion among the youth. From a methodological perspective, this trial is expected to provide information on the strength and challenges of implementing a partially app (internet) based trial in this context.

- BACKGROUND: Research on long-term health effects of earthquakes is scarce, especially in low- and middle-income countries, which are disproportionately affected by disasters. To date, progress in this area has been hampered by the lack of tools to accurately measure these effects. Here, we explored whether long-term public health effects of earthquakes can be assessed using a combination of readily available data sources on public health and geographic distribution of seismic activity.METHODS: We used childhood stunting as a proxy for public health effects. Data on stunting were attained from Demographic and Health Surveys. Earthquake data were obtained from U.S. Geological Survey's ShakeMaps, geographic information system-based maps that divide earthquake affected areas into different shaking intensity zones. We combined these two data sources to categorize the surveyed children into different earthquake exposure groups, based on how much their area of residence was affected by the earthquake. We assessed the feasibility of the approach using a real earthquake case--an 8.4 magnitude earthquake that hit southern Peru in 2001.RESULTS AND CONCLUSIONS: Our results indicate that the combination of health survey data and disaster data may offer a readily accessible and accurate method for determining the long-term public health consequences of a natural disaster. Our work allowed us to make pre- and post-earthquake comparisons of stunting, an important indicator of the well-being of a society, as well as comparisons between populations with different levels of exposure to the earthquake. Furthermore, the detailed GIS based data provided a precise and objective definition of earthquake exposure. Our approach should be considered in future public health and disaster research exploring the long-term effects of earthquakes and potentially other natural disasters.

- Skin and soft tissue infections caused by Staphylococcus aureus (SA-SSTIs) including methicillin-resistant Staphylococcus aureus (MRSA) have experienced a significant surge all over the world. Changing climatic factors are affecting the global burden of dermatological infections and there is a lack of information on the association between climatic factors and MRSA infections. Therefore, association of temperature and relative humidity (RH) with occurrence of SA-SSTIs (n = 387) and also MRSA (n = 251) was monitored for 18 months in the outpatient clinic at a tertiary care hospital located in Bhubaneswar, Odisha, India. The Kirby-Bauer disk diffusion method was used for antibiotic susceptibility testing. Time-series analysis was used to investigate the potential association of climatic factors (weekly averages of maximum temperature, minimum temperature and RH) with weekly incidence of SA-SSTIs and MRSA infections. The analysis showed that a combination of weekly average maximum temperature above 33 °C coinciding with weekly average RH ranging between 55% and 78%, is most favorable for the occurrence of SA-SSTIs and MRSA and within these parameters, each unit increase in occurrence of MRSA was associated with increase in weekly average maximum temperature of 1.7 °C (p = 0.044) and weekly average RH increase of 10% (p = 0.097).

- Background: High out-of-pocket expenditures (OOPE) make delivery care difficult to access for a large proportion of India’s population. Given that home deliveries increase the risk of maternal mortality, in 2005 the Indian Government implemented the Janani Suraksha Yojana (JSY) program to incentivize poor women to deliver in public health facilities by providing a cash transfer upon discharge. We study the OOPE among JSY beneficiaries and women who deliver at home, and predictors of OOPE in two districts of Madhya Pradesh.Methods: September 2013 to April 2015 a cross-sectional community-based survey was performed. All recently delivered women were interviewed to elicit delivery costs, socio-demographic characteristics and delivery related information.Results: Most women (n = 1995, 84 %) delivered in JSY public health facility, the remaining 16 % (n = 386) delivered at home. Women who delivered under JSY program had a higher median, IQR OOPE ($8, 3–18) compared to home ($6, 2–13). Among JSY beneficiaries, poorest women had twice net gain ($20) versus wealthiest ($10) post cash transfer. Informal payments (64 %) and food/baby items (77 %) were the two most common sources of OOPE. OOPE made among JSY beneficiaries was pro-poor: poorer women made proportionally less expenditures compared to wealthier women. In an adjusted model, delivering in a JSY public facility increased odds of incurring expenditures (OR: 1.58, 95 % CI: 1.11–2.25) but at the same time to a 16 % (95 % CI: 0.73–0.96) decrease in the amount paid compared to home deliveries.Conclusions: OOPE is prevalent among JSY beneficiaries as well in home deliveries. In JSY, OOPE varies by income quintile: wealthier quintiles pay more OOPE. However the cash incentive is adequate enough to provide a net gain for all quintiles. OOPE was largely due to indirect costs and not direct medical payments. The program seems to be effective in providing financial protection for the most vulnerable groups.

- Interferon-g-inducible protein 10 (IP-10) has been suggested as a marker for targeted viral load (VL) monitoring during antiretroviral treatment (ART). We aimed to determine the kinetics of IP-10 during the initial year of ART, with particular regard to the impact of tuberculosis (TB) co-infection on IP-10 secretion. Longitudinal plasma IP-10 levels were quantified in 112 treatment-naive HIV-positive adults at Ethiopian health centers, through enzyme-linked immunosorbent assay (ELISA) using samples obtained before and during the initial 12 months of ART. All participants underwent bacteriological TB investigation before starting ART. In virological responders (VRs; defined as VL, 150 copies/ml with no subsequent VL $ 1,000 copies/ml), IP-10 kinetics were analyzed using linear regression models. Among 91/112 (81.3%) participants classified as VRs, 17 (18.7%) had concomitant TB. Median baseline IP-10 was 650 pg/ml (interquartile range [IQR], 428–1,002) in VRs. IP-10 decline was more rapid during the first month of ART (median 306 pg/ml/month) compared with later time intervals (median 7-48 pg/ml/month, P, 0.001 in each comparison). Although VRs with TB had higher IP-10 levels at baseline (median 1106 pg/ml [IQR, 627–1,704]), compared with individuals without TB (median 628 pg/ml [IQR, 391–885]; P = 0.003), the rate of IP-10 decline during ART was similar, regardless of TB-status. During the initial year of ART, IP-10 kinetics followed a biphasic pattern in VRs, with a more rapid decline in the first month of ART compared with later time intervals. Baseline IP-10 was higher in individuals with TB versus individuals without TB, but the kinetics during ART were similar. IMPORTANCE To reach the goal of elimination of HIV as public health threat, access to antiretroviral treatment (ART) has to be further scaled up. To ensure viral suppression in individuals receiving ART, novel and robust systems for treatment monitoring are required. Targeting viral load monitoring to identify individuals at increased likelihood of treatment failure, using screening tools, could be an effective use of limited resources for viral load testing. Interferon-g-inducible protein 10 (IP-10), a host inflammation mediator, has shown potential for this purpose. Here, we have investigated IP-10 kinetics in Ethiopian adults with HIV during the initial year after ART initiation. IP-10 levels decreased in parallel with viral load during ART, and prevalent tuberculosis at ART initiation did not influence IP-10 kinetics. This study shows satisfactory performance for IP-10 as a surrogate marker for viral load in persons starting ART, with no influence of concomitant tuberculosis.
