Abstract
OBJECTIVES To address existing inequalities, the Barcelona City Council launched a Neighbourhood Plan in 2016-2020. During the first wave of the COVID-19 pandemic, the Neighbourhood Plan interventions were intensified. This study aimed to assess the effect of the plan on the incidence of COVID-19 during the first wave of the pandemic in Barcelona. STUDY DESIGN We used a quasi-experimental design with 16 intervention neighbourhoods and 17 neighbourhoods in the comparison group with similar socioeconomic characteristics. METHODS We calculated the cumulative incidence rate (CIR) of COVID-19 per 100,000 inhabitants by sex, age groups, and neighbourhood of residence. Poisson regression models were fitted to estimate the crude relative risk and relative risk adjusted by socioeconomic status (cRR and aRR) and their 95% confidence intervals (CIs). RESULTS The CIR of COVID-19 was lower in the intervention neighbourhoods (CIR: 841 per 100,000 inhabitants) than in the comparison group (CIR: 973 per 100,000 inhabitants). On multivariate analysis, the aRR was 0.77 (CI: 0.70-0.83) for men and 0.89 (CI: 0.83-0.96) for women. Among men older than 75 years (aRR = 0.73; CI: 0.62-0.86), statistically significant differences were found in the intervention neighbourhoods compared to the comparison group. This pattern was not observed in women older than 75 years (aRR = 1.13; CI: 0.99-1.30). CONCLUSION This research finds positive short-term effect in the intervention neighbourhoods. We conclude that the COVID-19 control and prevention interventions are likely to explain the better performance in the neighbourhoods included in the Neighbourhood Plan.

Abstract
Minute insects such as parasitic micro-wasps have high basic and applied importance for their widespread use as biocontrol agents. Their dispersal is a phenotype of particular interest. Classically, it is evaluated using field releases, but those are time consuming, costly, and their results highly variable, preventing high-throughput and repeatability. Alternatively, dispersal can be studied using small-scale assays, but those neglect important higher-scale processes. Consequently, proper evaluation of dispersal is often complicated or lacking in academic studies and biocontrol breeding programs. Here we introduce a new method, the double-spiral maze, that allows the study of spatial propagation of groups of micro-wasps at relevant scales (several hours and meters), retaining high throughput and experimental power. The method records the location of every individual at every time, enabling accurate estimates of diffusion coefficients or other dispersal metrics. We describe this affordable, scalable, and easy-to-implement method, and illustrate its application with a species of agricultural interest.

Abstract
Abstract
Introduction
COVID-19 pandemic brought multiple negative consequences that go beyond the direct damage caused by the disease and that affect health systems as well. Complaints of attacks against health care workers became frequent and concerning. The objective of this survey was to characterize the frequency and type of violent behavior against front-line professionals in Latin America.
Material and methods
A cross-sectional electronic survey was carried out between January 11th to February 28th, 2022. Different health care workers from Latin America who have been delivering care at least from March 2020, regardless of whether they assist or not patients with COVID-19 were included. A non-probabilistic snowball sampling was performed, and the survey was
Results
The survey was responded by 3,544 participants from 19 countries (Figure 1); 58.5% were women, and the mean age was 41.9±11 years. The 70.8% were doctors, 16% nurses, 3.4% physiotherapists, and the remaining 9.8% had other functions within the health team. About 85.1% of physicians were specialists: 33.9% were cardiologists, 14.4% were intensivists or emergency physicians, 10.9% had some surgical specialty, 7.7% were pediatricians or related subspecialties, and the remaining 33.1% had other specialties. The 36.3% and 28.8% worked in public and private practice respectively, the remaining worked in both. Direct and regular care to COVID-19 patients was provided by 74.7% of all contestants.
Among the participants, 54.8% reported acts of violence: 95.6% suffered verbal violence, 11.1% physical violence, and 19.9% other types. 39.5% of respondents experienced it at least once a week. The acts of violence involved patients' relatives (32%), or patients together with their relatives (35.1%). The victims rated the stress level of these events with an average of 8.2±1.8 points (scale from 1 to 10). Approximately half of the health personnel who suffered an assault experienced psychosomatic symptoms after the traumatic event (Figure 2). Among the victims of violence, 56.2% considered changing their care tasks, and 33.6% abandoning their profession. However, only 23% of the health personnel attacked stated that they had made some type of legal action regarding these acts.
In a logistic regression model, doctors (OR 1.95, p<0.01), nurses (OR 1.77, p=0.001), and administrative staff (OR 3.20, p<0.01) suffered more violence than other health workers. Women more frequently suffered violence (OR 1.56, p<0.01), as well as those who worked with patients with COVID-19 (OR 3.59, p<0.01). Conversely, a lower probability of violence was observed at older ages (OR 0.96, p<0.01).
Conclusion
We detected a high prevalence of violence against health personnel in Latin America during the current pandemic. Those caring for COVID-19 patients, younger staff, and women were found to be more vulnerable. It is imperative to develop strategies to mitigate these acts and their repercussions on the health team.

Search for Dark-Matter-Induced Oscillations of Fundamental Constants Using Molecular Spectroscopy. PHYSICAL REVIEW LETTERS 2022; 129:031302. [PMID: 35905348 DOI: 10.1103/physrevlett.129.031302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 04/07/2022] [Accepted: 06/02/2022] [Indexed: 06/15/2023]
Abstract
A possible implication of an ultralight dark matter field interacting with the standard model degrees of freedom is oscillations of fundamental constants. Here, we establish direct experimental bounds on the coupling of an oscillating ultralight dark matter field to the up, down, and strange quarks and to the gluons, for oscillation frequencies between 10 and 10^{8} Hz. We employ spectroscopic experiments that take advantage of the dependence of molecular transition frequencies on the nuclear masses. Our results apply to previously unexplored frequency bands and improve on existing bounds at frequencies >5 MHz. We also improve on the bounds for coupling to the electromagnetic field and the electron field, in particular spectral windows. We identify a sector of ultralight dark matter and standard model coupling space where the bounds from equivalence principle tests may be challenged by next-generation experiments of the present kind.

Combining plasma extracellular vesicle Let-7b-5p, miR-184 and circulating miR-22-3p levels for NSCLC diagnosis and drug resistance prediction. Sci Rep 2022; 12:6693. [PMID: 35461372 PMCID: PMC9035169 DOI: 10.1038/s41598-022-10598-x] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Accepted: 04/05/2022] [Indexed: 01/04/2023] Open
Abstract
Low-dose computed tomography (LDCT) Non-Small Cell Lung (NSCLC) screening is associated with high false-positive rates, leading to unnecessary expensive and invasive follow ups. There is a need for minimally invasive approaches to improve the accuracy of NSCLC diagnosis. In addition, NSCLC patients harboring sensitizing mutations in epidermal growth factor receptor EGFR (T790M, L578R) are treated with Osimertinib, a potent tyrosine kinase inhibitor (TKI). However, nearly all patients develop TKI resistance. The underlying mechanisms are not fully understood. Plasma extracellular vesicle (EV) and circulating microRNA (miRNA) have been proposed as biomarkers for cancer screening and to inform treatment decisions. However, the identification of highly sensitive and broadly predictive core miRNA signatures remains a challenge. Also, how these systemic and diverse miRNAs impact cancer drug response is not well understood. Using an integrative approach, we examined plasma EV and circulating miRNA isolated from NSCLC patients versus screening controls with a similar risk profile. We found that combining EV (Hsa-miR-184, Let-7b-5p) and circulating (Hsa-miR-22-3p) miRNAs abundance robustly discriminates between NSCLC patients and high-risk cancer-free controls. Further, we found that Hsa-miR-22-3p, Hsa-miR-184, and Let-7b-5p functionally converge on WNT/βcatenin and mTOR/AKT signaling axes, known cancer therapy resistance signals. Targeting Hsa-miR-22-3p and Hsa-miR-184 desensitized EGFR-mutated (T790M, L578R) NSCLC cells to Osimertinib. These findings suggest that the expression levels of circulating hsa-miR-22-3p combined with EV hsa-miR-184 and Let-7b-5p levels potentially define a core biomarker signature for improving the accuracy of NSCLC diagnosis. Importantly, these biomarkers have the potential to enable prospective identification of patients who are at risk of responding poorly to Osimertinib alone but likely to benefit from Osimertinib/AKT blockade combination treatments.

Abstract
BACKGROUND Auscultation of heart and lung sounds is a foundational competency for Registered Nurses (RNs). Precise and timely assessments are important for the early detection and recognition of the deteriorating patient. Studies have shown that improved teaching methods that incorporate emerging technologies and address different learning styles are needed to improve competency in auscultation. METHOD Undergraduate nursing students (n = 127) were randomized into treatment and control groups. The control group received the usual preparation in auscultation learning strategies. The treatment group received the usual training plus three auscultation learning sessions that were each 2 h in length (cardiac, pulmonary and mixed sounds). RESULTS The virtual auscultation teaching strategy had a significant impact on undergraduate nursing student's competency in recognizing heart murmurs. The treatment group also had increased scores compared to the control group increased scores in distinguishing normal versus abnormal heart and lung sounds, identification of crackles and diminished breath sounds. CONCLUSION Virtual auscultation as a teaching strategy was shown to have a positive impact on undergraduate student nurse competence in accurately identifying heart and lung sounds.

Abstract
Among the prominent candidates for dark matter are bosonic fields with small scalar couplings to the standard-model particles. Several techniques are employed to search for such couplings, and the current best constraints are derived from tests of gravity or atomic probes. In experiments employing atoms, observables would arise from expected dark-matter-induced oscillations in the fundamental constants of nature. These studies are primarily sensitive to underlying particle masses below 10^{-14} eV. We present a method to search for fast oscillations of fundamental constants using atomic spectroscopy in cesium vapor. We demonstrate sensitivity to scalar interactions of dark matter associated with a particle mass in the range 8×10^{-11} to 4×10^{-7} eV. In this range our experiment yields constraints on such interactions, which within the framework of an astronomical-size dark matter structure are comparable with, or better than, those provided by experiments probing deviations from the law of gravity.

Abstract
Background A 9-valent human papillomavirus-6/11/16/18/31/33/45/52/58 (9vHPV) vaccine extends coverage to 5 next most common oncogenic types (31/33/45/52/58) in cervical cancer versus quadrivalent HPV (qHPV) vaccine. We describe efficacy, immunogenicity, and safety in Asian participants (India, Hong Kong, South Korea, Japan, Taiwan, and Thailand) from 2 international studies: a randomized, double-blinded, qHPV vaccine-controlled efficacy study (young women aged 16–26 years; NCT00543543; Study 001); and an immunogenicity study (girls and boys aged 9–15 years; NCT00943722; Study 002). Methods Participants (N = 2519) were vaccinated at day 1 and months 2 and 6. Gynecological samples (Study 001 only) and serum were collected for HPV DNA and antibody assessments, respectively. Injection-site and systemic adverse events (AEs) were monitored. Data were analyzed by country and vaccination group. Results 9vHPV vaccine prevented HPV-31/33/45/52/58–related persistent infection with 90.4%–100% efficacy across included countries. At month 7, ≥97.9% of participants seroconverted for each HPV type. Injection-site AEs occurred in 77.7%–83.1% and 81.9%–87.5% of qHPV and 9vHPV vaccine recipients in Study 001, respectively, and 62.4%–85.7% of girls/boys in Study 002; most were mild to moderate. Conclusions The 9vHPV vaccine is efficacious, immunogenic, and well tolerated in Asian participants. Data support 9vHPV vaccination programs in Asia. Clinical Trials Registration NCT00543543; NCT00943722.

Abstract
Layered double hydroxides show intriguing physical and chemical properties arising by their intrinsic self-assembled stacking of molecular-thick 2D nanosheets, enhanced active surface area, hosting of guest species by intercalation and anion exchanging capabilities. Here, we report on the unprecedented emerging intense ultraviolet photoluminescence in Zn/Al layered double hydroxide high-aspect-ratio nanoplatelets, which we discovered to be fully activated by drying under vacuum condition and thermal desorption as well. Photoluminescence and its quenching were reproducibly switched by a dehydration–hydration process. Photoluminescence properties were comprehensively evaluated, such as temperature dependence of photoluminescence features and lifetime measurements. The role of 2D morphology and arrangement of hydroxide layers was demonstrated by evaluating the photoluminescence before and after exfoliation of a bulk phase synthetized by a coprecipitation method.

Abstract
Leishmaniasis is a zoonotic disease caused by intracellular protozoa of the Leishmania genus that are spread and transmitted by sandflies. Natural infection and clinical disease in domestic cats and dogs appear to be rare or perhaps largely under-reported in endemic areas. However, previous reports on infected domestic animals usually implicate the same Leishmania species that affect humans in tropical and subtropical areas of the world suggesting a potential role for zoonotic transmission. In the present study we assessed a representative sample of cats and dogs from endemic urban / suburban areas of Lara state in central western Venezuela. In both dogs and cats, cutaneous disease exhibits a spectrum of manifestations that range from single papules or nodules, which may evolve into ulcerative, plaque-like or scaly lesions. Cytochrome b (cyt b) PCR gene sequence analysis revealed L. mexicana as the causative agent in all cases, including two human cases proceeding from the same study area at the same time the study was carried out. In order to improve our understanding on feline/canine infection with Leishmania mexicana, and address potential zoonotic concerns it is necessary to characterize its enzootic reservoirs and vectors as well as the possible anthropophilic players linking to the peridomestic and domestic cycles.

Abstract
UNLABELLED By the end of 2018, 42 years after the landing of the two Viking seismometers on Mars, InSight will deploy onto Mars' surface the SEIS (Seismic Experiment for Internal Structure) instrument; a six-axes seismometer equipped with both a long-period three-axes Very Broad Band (VBB) instrument and a three-axes short-period (SP) instrument. These six sensors will cover a broad range of the seismic bandwidth, from 0.01 Hz to 50 Hz, with possible extension to longer periods. Data will be transmitted in the form of three continuous VBB components at 2 sample per second (sps), an estimation of the short period energy content from the SP at 1 sps and a continuous compound VBB/SP vertical axis at 10 sps. The continuous streams will be augmented by requested event data with sample rates from 20 to 100 sps. SEIS will improve upon the existing resolution of Viking's Mars seismic monitoring by a factor of ∼ 2500 at 1 Hz and ∼ 200 000 at 0.1 Hz. An additional major improvement is that, contrary to Viking, the seismometers will be deployed via a robotic arm directly onto Mars' surface and will be protected against temperature and wind by highly efficient thermal and wind shielding. Based on existing knowledge of Mars, it is reasonable to infer a moment magnitude detection threshold of M w ∼ 3 at 40 ∘ epicentral distance and a potential to detect several tens of quakes and about five impacts per year. In this paper, we first describe the science goals of the experiment and the rationale used to define its requirements. We then provide a detailed description of the hardware, from the sensors to the deployment system and associated performance, including transfer functions of the seismic sensors and temperature sensors. We conclude by describing the experiment ground segment, including data processing services, outreach and education networks and provide a description of the format to be used for future data distribution.

Abstract
A number of HIV prevention interventions for male couples are in the pipeline for development as few evidence-based ones exist. Among these projects, none include all three groups of male couples (concordant HIV-negative, HIV-discordant, and concordant HIV-positive) as their target population, and only two are eHealth-based. The present qualitative study sought to assess whether one of the eHealth HIV prevention interventions for concordant HIV-negative male couples - called MCAP - could be adapted to meet the relationship and HIV prevention needs of HIV-discordant and HIV-positive male couples. Data for this study are drawn from in-person, individual-level interviews conducted with a convenience sample of 10 HIV-discordant male couples (n = 20) and 8 HIV-positive male couples (n = 16) from the Miami-Fort Lauderdale metro area in 2016. Thematic analysis was conducted to identify patterns (themes) of partners' thoughts about the toolkit, including how they perceived it could be improved for their own relationship and other couple's relationships. Two themes emerged from analysis of the qualitative data suggesting how the participants wanted the toolkit to be improved to meet their needs. Specifically, participants recommended for the toolkit to include guidance about integrating the use of biomedical HIV prevention strategies into couple's relationships, as well as for how partners can best take care of each other and further protect themselves from HIV and/or other STIs (Prevention Guidance). In addition, participants requested for the concept of sexual agreements to be broadened to include other aspects they deemed to be important in their life (e.g., mental health, exercise and nutrition) (Holistic agreements). Findings from the present study illuminate the ways in which MCAP would need to be adapted for these two groups of male couples in order to meet the needs for all three groups of male couples in the U.S. in a future iteration of this intervention.

Abstract
Background Surrogate biomarkers of efficacy are needed for anti-PD1/PD-L1 therapy, given the existence of delayed responses and pseudo-progressions. We evaluated changes in serum IL-8 levels as a biomarker of response to anti-PD-1 blockade in melanoma and non-small-cell lung cancer (NSCLC) patients. Patients and methods Metastatic melanoma and NSCLC patients treated with nivolumab or pembrolizumab alone or nivolumab plus ipilimumab were studied. Serum was collected at baseline; at 2-4 weeks after the first dose; and at the time-points of response evaluation. Serum IL-8 levels were determined by sandwich ELISA. Changes in serum IL-8 levels were compared with the Wilcoxon test and their strength of association with response was assessed with the Mann-Whitney test. Accuracy of changes in IL-8 levels to predict response was estimated using receiver operation characteristics curves. Results Twenty-nine melanoma patients treated with nivolumab or pembrolizumab were studied. In responding patients, serum IL-8 levels significantly decreased between baseline and best response (P <0.001), and significantly increased upon progression (P = 0.004). In non-responders, IL-8 levels significantly increased between baseline and progression (P = 0.013). Early changes in serum IL-8 levels (2-4 weeks after treatment initiation) were strongly associated with response (P <0.001). These observations were validated in 19 NSCLC patients treated with nivolumab or pembrolizumab (P = 0.001), and in 15 melanoma patients treated with nivolumab plus ipilimumab (P <0.001). Early decreases in serum IL-8 levels were associated with longer overall survival in melanoma (P = 0.001) and NSCLC (P = 0.015) patients. Serum IL-8 levels also correctly reflected true response in three cancer patients presenting pseudoprogression. Conclusions Changes in serum IL-8 levels could be used to monitor and predict clinical benefit from immune checkpoint blockade in melanoma and NSCLC patients.

On the challenge of estimating diphoton backgrounds at large invariant mass. THE EUROPEAN PHYSICAL JOURNAL. C, PARTICLES AND FIELDS 2017; 77:126. [PMID: 28331431 PMCID: PMC5341208 DOI: 10.1140/epjc/s10052-017-4687-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/07/2016] [Accepted: 02/08/2017] [Indexed: 06/06/2023]
Abstract
We examine, using the analyses of the 750 GeV diphoton resonance as a case study, the methodology for estimating the dominant backgrounds to diphoton resonance searches. We show that close to the high energy tails of the distributions, where background estimates rely on functional extrapolations or Monte Carlo predictions, large uncertainties are introduced, in particular by the challenging photon-jet background. Analyses with loose photon and low photon [Formula: see text] cuts and those susceptible to high photon rapidity regions are especially affected. Given that diphoton-based searches beyond 1 TeV are highly motivated as discovery modes, these considerations are relevant for future analyses. We first consider a physics-driven deformation of the photon-jet spectrum by next-to-leading order effects and a phase space dependent fake rate and show that this reduces the local significance of the excess. Using a simple but more general ansatz, we demonstrate that the originally reported local significances of the 750 GeV excess could have been overestimated by more than one standard deviation. We furthermore cross-check our analysis by comparing fit results based on the 2015 and 2016 LHC data sets. Finally we employ our methodology on the available 13 TeV LHC data set assessing the systematics involved in the current diphoton searches beyond the TeV region.

Abstract
OBJECTIVE To emphasize prognostic factors of hyperbaric oxygen therapy (HBOT) on hematuria at 3 and 12 months in the context of a radiation cystitis. MATERIAL AND METHODS A cohort of 134 patients was treated from 2008 to 2013 in the hyperbaric medicine center of Toulouse University Hospital, France for radiation cystitis. Hematuria was ranked using the SOMA score. HBOT has been applied according to a standardized protocol of 20 renewable sessions, with pure oxygen to 2.5 ATA. The median number of sessions at 12 months was 50. RESULTS HBOT had an efficacy of 83% at 3 months and 81% at 12 months. Twenty percent of patients had minor side effects. Compared to the pre-HBOT period, the number of hospitalizations decreased by 75% following treatment. The efficacy at 3 months was predictive of efficacy at 12 months (P<0.0001). There was an inverse correlation between the initial grade and efficacy at 3 months (P=0.026) and 12 months (P=0.001). A high WHO status diminished HBOT efficacy at 3 and 12 months (P=0.0014 and P<0.0001, respectively). An anticoagulant intake decreased the HBOT response at 12 months (P=0.002). Other parameters had no effects on efficacy. CONCLUSION The efficacy at 3 months seems to be predictive of efficacy at 12 months. The initial hematuria grade is inversely correlated with efficacy at 3 and 12 months. It appears necessary to achieve at least 32 HBOT sessions. Moreover, a high WHO status and an anticoagulant intake seem to have a negative prognostic value. LEVEL OF EVIDENCE 4.

Abstract
Anaplasma phagocytophilum is an emerging zoonotic tick-borne pathogen affecting a wide range of mammals. Rodents are suspected to be natural reservoirs for this bacterium, but their role in the epidemiologic cycles affecting domestic animals and wild ungulates has not been demonstrated. This study aimed to improve our knowledge on A. phagocytophilum prevalence in Apodemus sylvaticus, A. flavicollis and Myodes glareolus using data collected in 2010 in one area in eastern France and in 2012-2013 in two others areas in western France. Rodents were captured in each site and infection was tested using qualitative real-time PCR assays on either blood or spleen samples. Prevalence showed high variability among sites. The highest prevalence was observed in the most eastern site (with an average infection rate of 22.8% across all species), whereas no rodent was found to be PCR positive in the south-west site and only 6.6% were positive in the north-west of France. Finally, a significant increase in prevalence was observed in autumn samples compared to spring samples in the north-west, but no change was found in the other two sites.

Abstract
Epidemiological studies on benign lesions related to human papillomavirus (HPV) infection are scarce in Latin America. We enrolled 342 consecutive patients with lesions suspected of being genital warts (GW). All patients underwent confirmatory biopsy and GP5+/GP6+/- Reverse Line Blot HPV testing on frozen tissue. In 261 (81%) cases, the diagnosis was confirmed by histopathology and HPV was detected in 90.6% of men and 87.7% of women. HPV 6 was by far the most common type in both women (62%) and men (56%), followed by HPV 11 (∼20%). Co-infection with these two types occurred in 7% and 12% of women and men, respectively. HPV16 ranked third in prevalence, with 16% of patients testing positive. Twenty-five percent of cases tested positive for multiple HPV genotypes. Although HPV 6 and HPV 11 were the main types detected and no differences between men and women were observed, we found HPV 11 contributed more to GW aetiology compared with previous reports, showing a variability of HPV type distribution in GW across populations. This information is valuable baseline data in Latin America for future estimations of the burden of GW in men and women and shows the potential benefit obtainable by prophylactic vaccination against HPV types 6 and 11.

Abstract
AIM HIV infection is strongly associated with accelerated vascular atherosclerosis and increased cardiovascular events. The prevalence of peripheral arterial disease (PAD) in HIV infected patients is not clearly defined and the results of different reports are contradicting. OBJECTIVE To determine the prevalence of abnormal Ankle Brachial Index (ABI) and associated risk factors in HIV infected population. METHODS The ABI was measured manually using 5.0 MHz handheld Doppler probe in 173 HIV infected patients. The cohort was categorized according to the ABI measurements as; normal group (ABI 0.9 to 1.3), peripheral arterial disease (PAD) group (ABI<0.9), and High ABI group (ABI>1.3). Several demographic, atherosclerosis risk factors and HIV infection parameters have been evaluated as potential risk factors. RESULTS Median age of the cohort was 49 years (inter-quartile ranges [IQR]: 42.5 to 54); 63.4% were males. Abnormal ABI was found in 47(27.2%) patients; twenty four (13.9%) had PAD and 23(13.3%) had high ABI. Among the risk factors evaluated, we observed that PAD group is associated with diabetes (Relative risk [RR]: 4.19; 95% confidence interval [CL]: 2.13 to 8.27; P=0.0002) and age above 49 (Relative risk [RR]: 3.96; 95% confidence interval [CL]: 1.56 to 10.0; P=0.002). However, the High ABI group was significantly associated with male gender (RR: 3.94; 95% CI: 1.23 to 12.70; P=0.009). CONCLUSION HIV infection is associated with increased prevalence of abnormal resting ABI.
