[History of clinical electrophysiology in diagnosing and treatment monitoring of high ventricular vulnerability]. / Geschichte der klinischen Elektrophysiologie in Diagnostik und Therapiekontrolle ventrikulärer Vulnerabilität.

The paper presents the history of hope from 1980-1995 to predict the risk of sudden arrhythmic death using electrophysiologic techniques in individual patients. Even if this prediction seems possible in selected highly risk cohorts, many more patients will die in ventricular arrhythmia without fulfilling the criteria. Ultimately, high risk of sudden cardiac death can be predicted in selected patient groups, but not in the majority of patients at risk. It is a history of dashed hope.

[Research on Logic Design of Proton Treatment Control System].

The proton treatment control system is the supporting software of the proton therapy device, which specifically coordinates and controls the status and work of each subsystem. In this study, the software architecture and hardware implementation of the proton treatment control system was developed and built a foundation for the overall debugging. Using C# programming language and WPF programming techniques, TCP network communication protocol specified by the proton treatment technical document and MVVM pattern in Windows system, the logic design and implementation of each level were studied. Meanwhile, the communication interface between the subsystems under TCP communication protocol was agreed. The logic design and research of the setup field and treatment field were carried out. And the User Interface was designed and developed using the above technology. The program realizes the communication and interaction between the proton treatment control system and each subsystem, so as to control and monitor the whole treatment process. The proton treatment control system provides a software basis for the remote overall debugging and on-line monitor and control of proton treatment device.

Factors associated with post-treatment control of viral load in HIV-infected patients: a systematic review and meta-analysis.

OBJECTIVES: This study aimed to investigate the factors associated with maintenance of viral suppression after antiretroviral therapy (ART) discontinuation. METHODS: Databases were searched for studies published between January 01, 2011, and July 01, 2022, that correlated the time of virus rebound with treatment interruption (TI). The corresponding data were extracted from these studies. A fixed-effects model was used to calculate pooled estimates. RESULTS: Thirty-one studies were included in this analysis. Results showed that patients who started ART during acute or early infection had longer viral control than those who started ART during chronic infection. It has been reported that some broadly neutralizing HIV-1-specific antibodies can significantly prolong viral inhibition. The study also found that approximately 7.2% of patients achieved post-treatment control (PTC) approximately a year after TI. CONCLUSION: ART initiation in the acute or early phases can delay viral rebound after TI. Cell-associated HIV RNA and HIV DNA have been difficult to prove as able to predict viral rebound time. Many vaccines and antibodies have also been shown to be effective in prolonging viral control in people without PTC, and more research is needed to develop alternative ART therapies that can effectively inhibit or even eliminate HIV.

Cardiovascular Risk Factor Burden and Treatment Control in Patients with Chronic Kidney Disease: A Cross-Sectional Study.

AIM: Cardiovascular disease is a life-threatening chronic kidney disease (CKD) complication. Although cardiovascular risk factor management is significant in patients with CKD, there are few reports that detail the frequency of complications and the treatment of cardiovascular risk factors at different stages of CKD in clinical practice. METHODS: There were a total of 3,407 patients with non-dialysis-dependent CKD who participated in the Fukuoka Kidney disease Registry Study, and they were cross-sectionally analyzed. The patients were classified into five groups based on their estimated glomerular filtration rate and urinary albumin to creatinine ratio according to Kidney Disease: Improving Global Outcomes 2012 guidelines, which recommend low, moderate, high, very high, and extremely high risk groups. The primary outcomes were the cardiovascular risk factor burden and the treatment status of cardiovascular risk factors. Using a logistic regression model, the association between the CKD groups and the treatment status of each risk factor was examined. RESULTS: The proportion of patients with hypertension, diabetes mellitus, and dyslipidemia significantly increased as CKD progressed, whereas the proportion of patients who achieved cardiovascular risk factor treatment targets significantly decreased. In the multivariable analysis, the odds ratios (ORs) of uncontrolled treatment targets were significantly higher for hypertension (OR 3.68) in the extremely high risk group than in the low risk group. CONCLUSIONS: Patients with non-dialysis-dependent CKD demonstrate an increased cardiovascular risk factor burden with greater severity of CKD. Extremely high risk CKD is associated with difficulty in managing hypertension.

Gut microbiome signatures linked to HIV-1 reservoir size and viremia control.

BACKGROUND: The potential role of the gut microbiome as a predictor of immune-mediated HIV-1 control in the absence of antiretroviral therapy (ART) is still unknown. In the BCN02 clinical trial, which combined the MVA.HIVconsv immunogen with the latency-reversing agent romidepsin in early-ART treated HIV-1 infected individuals, 23% (3/13) of participants showed sustained low-levels of plasma viremia during 32 weeks of a monitored ART pause (MAP). Here, we present a multi-omics analysis to identify compositional and functional gut microbiome patterns associated with HIV-1 control in the BCN02 trial. RESULTS: Viremic controllers during the MAP (controllers) exhibited higher Bacteroidales/Clostridiales ratio and lower microbial gene richness before vaccination and throughout the study intervention when compared to non-controllers. Longitudinal assessment indicated that the gut microbiome of controllers was enriched in pro-inflammatory bacteria and depleted in butyrate-producing bacteria and methanogenic archaea. Functional profiling also showed that metabolic pathways related to fatty acid and lipid biosynthesis were significantly increased in controllers. Fecal metaproteome analyses confirmed that baseline functional differences were mainly driven by Clostridiales. Participants with high baseline Bacteroidales/Clostridiales ratio had increased pre-existing immune activation-related transcripts. The Bacteroidales/Clostridiales ratio as well as host immune-activation signatures inversely correlated with HIV-1 reservoir size. CONCLUSIONS: The present proof-of-concept study suggests the Bacteroidales/Clostridiales ratio as a novel gut microbiome signature associated with HIV-1 reservoir size and immune-mediated viral control after ART interruption.

The perceived impact of an HIV cure by people living with HIV and key populations vulnerable to HIV in the Netherlands: A qualitative study.

Introduction: When an HIV cure becomes available, it will have consequences for people living with HIV (PLHIV) and key populations who are vulnerable to HIV. This qualitative study aimed to explore the perceived impact of two HIV cure scenarios (post-treatment control when HIV is suppressed without the need for ongoing antiretroviral treatment (ART) and complete HIV elimination) on the quality of life of PLHIV and key populations living without HIV in the Netherlands. Methods: Participants were purposefully sampled from the Amsterdam Cohort Studies, the AGEhIV Cohort Study, the outpatient clinic of the University Medical Centre Utrecht and the Dutch HIV Association to increase variability. Semi-structured in-depth interviews were conducted between October 2020 and March 2021 and thematically analysed. Results: Of the 42 interviewed participants, 29 were PLHIV and 13 represented key populations (i.e., men who have sex with men and people injecting drugs). Both PLHIV and participants from vulnerable key populations hoped that a cure would result in normalization of their lives by removing the need to disclose HIV, reducing stigma and guilt, increasing independence of ART, and liberating sexual behaviour. Both groups believed only HIV elimination could accomplish this desired impact. Conclusions: While the post-treatment control scenario seems a more plausible outcome of current HIV cure research, our findings highlight that participants may not perceive it as a true cure. Involvement of PLHIV and vulnerable key populations in devising acceptable and feasible experimental approaches to HIV cure is essential to ensure their future successful implementation.

Efficient integration of aggregate data and individual participant data in one-way mixed models.

Often both aggregate data (AD) studies and individual participant data (IPD) studies are available for specific treatments. Combining these two sources of data could improve the overall meta-analytic estimates of treatment effects. Moreover, often for some studies with AD, the associated IPD maybe available, albeit at some extra effort or cost to the analyst. We propose a method for combining treatment effects across trials when the response is from the exponential family of distribution and hence a generalized linear model structure can be used. We consider the case when treatment effects are fixed and common across studies. Using the proposed combination method, we study the relative efficiency of analyzing all IPD studies vs combining various percentages of AD and IPD studies. For many different models, design constraints under which the AD estimators are the IPD estimators, and hence fully efficient, are known. For such models, we advocate a selection procedure that chooses AD studies over IPD studies in a manner that force least departure from design constraints and hence ensures an efficient combined AD and IPD estimator.

Diabetes severity measured by treatment control status and number of anti-diabetic drugs affects presenteeism among workers with type 2 diabetes.

BACKGROUND: The number of people with diabetes is increasing and resulting in major economic losses. Presenteeism accounts for the majority of economic losses, so measures against presenteeism are important. This study investigated the relationship between severity of type 2 diabetes and presenteeism. METHODS: A cross-sectional study was conducted among workers over 40 years of age. Participants were classified as normal group or diabetic treatment group using their medical examination results and health insurance claims data. Diabetic treatment groups were described by degree of treatment control: Good (HbA1c < 7%), Intermediate (7% ≤ HbA1c < 8%), and Poor (8% ≤ HbA1c). Therapy type was also divided into monotherapy and combination therapy. Logistic regression analysis was performed to predict presenteeism loss using the Quantity and Quality method. RESULTS: Data on 13,271 workers were analyzed. Presenteeism loss was significantly higher in all treatment control groups compared with the normal group, particularly for the intermediate and poor control groups. The monotherapy group did not differ from the normal group, but presenteeism loss was significantly higher in the combination therapy group than the normal group. CONCLUSIONS: Presenteeism loss in workers with diabetes may be affected by diabetes severity, and even if treatment control were good, presenteeism loss could occur when the number of anti-diabetic drugs was high. Therefore, it is important to provide early intervention and continuous support as a preventive measure against not only diabetes and diabetes-related complications but also presenteeism.

On an SE(Is)(Ih)AR epidemic model with combined vaccination and antiviral controls for COVID-19 pandemic.

In this paper, we study the nonnegativity and stability properties of the solutions of a newly proposed extended SEIR epidemic model, the so-called SE(Is)(Ih)AR epidemic model which might be of potential interest in the characterization and control of the COVID-19 pandemic evolution. The proposed model incorporates both asymptomatic infectious and hospitalized infectious subpopulations to the standard infectious subpopulation of the classical SEIR model. In parallel, it also incorporates feedback vaccination and antiviral treatment controls. The exposed subpopulation has three different transitions to the three kinds of infectious subpopulations under eventually different proportionality parameters. The existence of a unique disease-free equilibrium point and a unique endemic one is proved together with the calculation of their explicit components. Their local asymptotic stability properties and the attainability of the endemic equilibrium point are investigated based on the next generation matrix properties, the value of the basic reproduction number, and nonnegativity properties of the solution and its equilibrium states. The reproduction numbers in the presence of one or both controls is linked to the control-free reproduction number to emphasize that such a number decreases with the control gains. We also prove that, depending on the value of the basic reproduction number, only one of them is a global asymptotic attractor and that the solution has no limit cycles.

[A survey among family doctors on care reality of patients under oral tyrosine kinase inhibitor therapies]. / Befragung von Hausärzt*innen zur Versorgung von Patienten unter oralen Tyrosinkinaseinhibitoren.

INTRODUCTION: Oral tyrosine kinase inhibitor (TKI) therapies are becoming increasingly more important in the treatment of malignant diseases. Monitoring with focus on adherence, side effects and interactions poses new challenges for medical care. The role and capabilities of family doctors in the care of TKI patients are yet unclear and should be uncovered in a nationwide survey. METHODS: From April to July 2016, 3,000 family doctors in Germany were asked to complete a written questionnaire regarding their capabilities for co-supervision of TKI patients. RESULTS: The response rate was 18% (n=553). The peak age was between 50 and 60 years. 81% were specialists in general medicine, 14% specialists in internal medicine and 5% general practitioners. 98% cared for no or less than 10 TKI patients per quarter. Knowledge of side effects and interaction potential of TKIs was low in over 90%. 83% preferred monitoring by the treating oncologist and 93% felt uncertain about treatment monitoring. The control of adherence was of little importance in 66%. The number of treated TKI patients had a significant impact on knowledge and opportunities for treatment monitoring. There was a significant correlation between knowledge about TKIs and confidence in treatment monitoring. In general, younger doctors tended to be more confident in treatment monitoring, and specialists in internal medicine tended to have more knowledge than specialists in general medicine general practitioners and general practitioners. DISCUSSION: Currently, the low number of TKI patients, little knowledge about TKI, and the desire for specialist care are limiting the possibilities of co-caring for TKI patients by family doctors. CONCLUSION: Although family doctors are generally motivated to care for tumor patients, routine treatment controls of TKI patients conducted by family doctors seem hardly possible at the moment and should currently remain with the specialist.

Interrupting traumatic memories in the emergency department: a randomized controlled pilot study.

BACKGROUND: The hours immediately following a traumatic event may present a window of opportunity to interrupt the consolidation of memories of the traumatic event, and this may prevent PTSD development. This theory has been validated in a series of analogue studies, showing that a visuo-spatial task reduces intrusive memories, however clinical studies are scarce. OBJECTIVE: This pilot RCT examined the use of a semi-immersive Virtual Reality visuospatial task, as an intervention to interrupt memory consolidation, in the Emergency Department (ED) in the immediate hours following a traumatic event. We hypothesised that participants who had received the intervention would present with lower levels of PTSD symptoms than the control group who received no intervention. METHOD: Seventy-seven adult survivors of traumatic events, meeting study criteria, were recruited in the ED of a Level III Trauma Centre. Survivors arrived at the ED less than one hour, on average, after the trauma. After signing informed consent, participants were randomized to the SnowWorld intervention or control group. Both groups completed self-report questionnaires, and the intervention group used SnowWorld for up to 10 minutes. RESULTS: No significant differences between the intervention and control groups were found regarding PTSD symptom levels two weeks and six months following the traumatic event. CONCLUSIONS: These results add to the growing literature examining the use of a concurrent task to reduce intrusions following a traumatic event. In contrast to previous clinical studies, this study did not show significant group differences; however, it replicates an analogue study that used a specifically developed app. Further studies are needed to elucidate possible reasons for these conflicting results.

Antecedentes: Las horas que siguen inmediatamente a un evento traumático podrían presentar una ventana de oportunidad para interrumpir la consolidación de las memorias del evento traumático, y esto podría prevenir el desarrollo del TEPT. Esta teoría ha sido validada en una serie de estudios análogos, mostrando que una tarea viso-espacial reduce las memorias intrusivas; los estudios clínicos son escasos.Objetivo: este ensayo controlado aleatorio (RCT en su sigla en inglés) piloto examinó el uso de una tarea viso-espacial de Realidad Virtual semi-inmersa como una intervención para interrumpir la memoria de consolidación en el Departamento de Emergencia, en las horas siguientes a un evento traumático. Hipotetizamos que al seguimiento aquellos que habían recibido la intervención presentarían niveles más bajos de los síntomas del TEPT que el grupo control.Método: Fueron reclutados en el Departamento de Emergencia (ED en su sigla en inglés) de un Centro de Trauma de Nivel III, 77 sobrevivientes adultos de eventos traumáticos, cumpliendo los criterios del estudio; los sobrevivientes llegaron al ED en promedio menos de una hora luego del trauma. Luego de firmar el consentimiento informado, fueron aleatorizados a la intervención SnowWorld o al grupo control. Ambos grupos completaron cuestionarios de auto-reporte, y el primer grupo usó SnowWorld por un máximo de 10 minutos.Resultados: No se encontraron diferencias significativas entre los grupos de estudio en los niveles de los síntomas de TEPT dos semanas y seis meses luego del evento traumático.Conclusiones: Este estudio no replicó los estudios clínicos y análogos previos. Esto puede deberse a las diferencias metodológicas, y los estudios futuros deberían tomarlos en cuenta.

The early impact of Scotland's minimum unit pricing policy on alcohol prices and sales.

In May 2018, Scotland became the first country in the world to enforce a minimum unit pricing (MUP) of 50 pence ($0.65; €0.55) on alcoholic beverages as a measure to control alcohol consumption and alcohol-related harms. This study presents early estimates of the impact of MUP on three outcomes: average price per unit (8 gr/10 ml) of alcohol, liters of alcohol sold per adult, and liters of alcohol sold per adult drinker, in three different settings: off-premise, on-premise, and both combined. Using yearly alcohol price and sales data from 2011 to 2019, I find that the average price per unit of alcohol has significantly risen post-MUP across all beverage categories (beer, spirits, wine, cider, and alcohol-all types), whereas liters of alcohol sold per adult and per adult drinker have significantly reduced for beer, spirits, cider, and alcohol-all types. For all outcomes, the impact of MUP on off-premise alcohol prices and sales is more pronounced than under the combined case, while no significant effects are found on-premise. These results are robust to model specification and to the addition of various control variables. Falsification tests changing the timing of the policy were performed and no significant results were found.

Rapid viral rebound after analytical treatment interruption in patients with very small HIV reservoir and minimal on-going viral transcription.

INTRODUCTION: Viral remission after analytical treatment interruption (ATI), termed post-treatment control, has been described in a small proportion of HIV-positive patients. This phenomenon has been separately associated to both low levels of HIV-1 proviral DNA as well as cell-associated RNA. We investigated whether the combination of both parameters could help predict delayed viral rebound after treatment interruption (TI). METHODS: We conducted an open single-arm ATI study in four Belgian HIV reference centres from January 2016 to July 2018. Eligible participants were adults who had fewer than 50 HIV-1 RNA copies/mL for more than two years, more than 500 CD4 cells/µL for more than three months, and were in general good health. Consenting participants who had fewer than 66 copies total HIV-1 DNA (t-DNA) and fewer than 10 copies cell-associated HIV-1 unspliced RNA (US-RNA) per million peripheral blood mononuclear cells (PBMCs), interrupted therapy and were monitored closely. Antiretroviral therapy (ART) was resumed after two consecutive viral loads exceeding 1000 copies or one exceeding 10,000 copies/mL. The primary outcome was the proportion of participants with fewer than 50 HIV-1 RNA copies/mL 48 weeks after TI. Secondary outcomes were time to viral rebound, the frequency of serious adverse events (AEs) and evolution of t-DNA and US-RNA after TI. RESULTS: All 16 consenting participants who interrupted therapy experienced rapid viral rebound two to eight weeks after TI. No serious AEs were observed. Levels of t-DNA and US-RNA increased after TI but returned to pre-ATI levels after treatment restart. None of the studied demographic, clinical and biological parameters were predictive of time of viral rebound. CONCLUSIONS: The combination of low levels of t-DNA and US-RNA in PBMCs, corresponding respectively to a small and transcriptionally silent viral reservoir, is not predictive of viral remission after TI in patients on ART.

Closed-loop control of targeted ultrasound drug delivery across the blood-brain/tumor barriers in a rat glioma model.

Cavitation-facilitated microbubble-mediated focused ultrasound therapy is a promising method of drug delivery across the blood-brain barrier (BBB) for treating many neurological disorders. Unlike ultrasound thermal therapies, during which magnetic resonance thermometry can serve as a reliable treatment control modality, real-time control of modulated BBB disruption with undetectable vascular damage remains a challenge. Here a closed-loop cavitation controlling paradigm that sustains stable cavitation while suppressing inertial cavitation behavior was designed and validated using a dual-transducer system operating at the clinically relevant ultrasound frequency of 274.3 kHz. Tests in the normal brain and in the F98 glioma model in vivo demonstrated that this controller enables reliable and damage-free delivery of a predetermined amount of the chemotherapeutic drug (liposomal doxorubicin) into the brain. The maximum concentration level of delivered doxorubicin exceeded levels previously shown (using uncontrolled sonication) to induce tumor regression and improve survival in rat glioma. These results confirmed the ability of the controller to modulate the drug delivery dosage within a therapeutically effective range, while improving safety control. It can be readily implemented clinically and potentially applied to other cavitation-enhanced ultrasound therapies.

Detección molecular del papilomavirus humano de alto riesgo en el seguimiento de mujeres tratadas por lesión escamosa intraepitelial / Molecular detection of high risk human papillomavirus in following women treated for squamous intraepithelial lesion

El cáncer de cuello uterino (CCU) es la primera causa de muerte por cáncer en mujeres en países en vías de desarrollo. La infección persistente por el virus papiloma humano (VPH) es un factor necesario en lesiones preneoplásicas y CCU. La citología cervicovaginal es el método mayormente utilizado para detectar el CCU y su uso combinado con la de detección de ADN viral seis meses post-tratamiento aumenta la efectividad para identificar mujeres tratadas con riesgo de lesión residual/recidiva. El objetivo fue describir la frecuencia de VPH de alto riesgo (AR) en mujeres tratadas por lesión escamosa intraepitelial (SIL) que acudieron al Servicio de Patología Cervical del Hospital San Pablo de enero-diciembre/2014. Se realizó un estudio descriptivo de corte transverso, que incluyó 80 pacientes que acudieron al servicio para control post-tratamiento por SIL. Se utilizó Cobas 4800 HPV Test (Roche) para la detección individual de VPH-16 y 18, y un pool de 10 VPH-AR (31,33,35,39,45,51,52,56,58,59) y dos de “probable” alto riesgo (66,68). Se encontró infección viral en el 7,5% (6/80) de las pacientes tratadas; identificándose VPH-16 en 3/6 de los casos positivos. En Paraguay existe alta incidencia de lesiones pre-neoplásicas y CCU siendo un problema de salud pública. Los datos observados sugieren que la utilización de este sistema para la detección viral puede llevar a optimizar el seguimiento post-tratamiento y la identificación de VPH-16 y 18 podría contribuir a la selección de pacientes en mayor riesgo de desarrollar una lesión cervical que deben someterse a una vigilancia frecuente y meticulosa.

Cervical cancer is the leading cause of cancer death in women in developing country.Persistent infection with human papillomavirus (HPV) is a necessary factor in premalignantlesions and cervical cancer. The Pap smear is the method most commonly used to detect thecervical cancer and its combined with the detection of viral DNA six months post-treatment increases effectiveness to identify women treated in risk with residual/recurrent lesion. Theaim was to describe the frequency of high-risk HPV (HR) in treated women for squamousintraepithelial lesion (SIL) who attended the Cervical Pathology Service of Hospital San Pablofrom January to December/2014. It is cross sectional, descriptive study which included 80patients who attended the service for post-treatment control. The 4800 Cobas HPV Test(Roche) was used, which detects HPV-16 and 18, and a pool of 10 HR-HPV(31,33,35,39,45,51,52,56,58,59) and two "probable" high risk (66,68). Viral infection wasfound in 7.5% (6/80) of patients treated; identifying HPV-16 in 3/6 of positive cases. InParaguay there is a high incidence of pre-neoplastic lesions and cervical cáncer remains apublic health problem. The observed data suggest that the use of this system for viraldetection can lead to optimize the post-treatment monitoring and the identification of HPV-16and 18 could contribute to the selection of patients at increased risk of developing cervicalinjury should undergo to frequent and careful monitoring.

Complex Dynamics of an SIR Epidemic Model with Saturated Incidence Rate and Treatment.

This paper describes a traditional SIR type epidemic model with saturated infection rate and treatment function. The dynamics of the model is studied from the point of view of stability and bifurcation. Basic reproduction number is obtained and it is shown that the model system may possess a backward bifurcation. The global asymptotic stability of the endemic equilibrium is studied with the help of a geometric approach. Optimal control problem is formulated and solved. Some numerical simulation works are carried out to validate our analytical results.

Genetics and the placebo effect: the placebome.

Placebos are indispensable controls in randomized clinical trials (RCTs), and placebo responses significantly contribute to routine clinical outcomes. Recent neurophysiological studies reveal neurotransmitter pathways that mediate placebo effects. Evidence that genetic variations in these pathways can modify placebo effects raises the possibility of using genetic screening to identify placebo responders and thereby increase RCT efficacy and improve therapeutic care. Furthermore, the possibility of interaction between placebo and drug molecular pathways warrants consideration in RCT design. The study of genomic effects on placebo response, 'the placebome', is in its infancy. Here, we review evidence from placebo studies and RCTs to identify putative genes in the placebome, examine evidence for placebo-drug interactions, and discuss implications for RCTs and clinical care.

[High blood pressure and obesity: disparities among four French overseas territories]. / Hypertension artérielle et obésité : disparités entre quatre régions d'Outre-mer.

BACKGROUND AND PURPOSE: The epidemiological characteristics of hypertension and obesity in French overseas territories (FOTs) have never been compared. METHODS: This cross-sectional survey included representative population-based samples of 602, 601, 620 and 605 men and women aged more than 15 years, respectively, from four FOTs of Guadeloupe, Martinique, French Guiana, and French Polynesia. Hypertension was defined as blood pressure (BP) at least 140/90mmHg or the current use of antihypertensive treatment. RESULTS: The prevalence of hypertension was 29.2% in Guadeloupe, 17.9% in French Guiana, 27.6% in Martinique and 24.5% in French Polynesia. Considering the Guadeloupe population as the reference group, prevalence of hypertension was significantly lower in French Guiana (P<0.001), even after controlling for age and sex (PU0.006). Awareness and treatment of hypertension were similar in French Guiana, Martinique and Guadeloupe (68.8-75.1% and 69.0-73.4%, respectively). Awareness was lower in French Polynesia (50.0%, adjusted P value U0.04), as was treatment of hypertension (32.4%, adjusted P value U0.001). Control of hypertension was also lower in French Polynesia (8.8%, adjusted P value U0.001) compared with the other territories (29.7-31.8%). French Polynesia had the highest prevalence of obesity (33.1%, adjusted P value<0.001) as compared with the other territories (17.9-22.8%). It had also the largest population attributable fraction of hypertension due to obesity (35.5%) compared with Guadeloupe (13.3%), Martinique (12.3%) and French Guiana (23.6%). CONCLUSION: Wide variations were observed in the prevalence and the management of hypertension between these FOTs, and an especially challenging low control of hypertension was found in French Polynesia. Obesity appears a key target to prevent hypertension, particularly in French Polynesia.

Detección del virus del papiloma humano de alto riesgo por captura híbrida II® según hallazgos citológicos en mujeres tratadas por lesiones escamosas intraepiteliales de cuello uterino, período 2006/2010 / Detection of high risk human papillomavirus by hybrid capture II(r) according cytological findings in women treated for squamous intraepithelial lesions of the cervix, period 2006/2010

OBJETIVO: Determinar la frecuencia del virus de papiloma humano de alto riesgo oncogénico (HR-HPV) por captura híbrida II (r) (CH II(r)) según hallazgos citológicos en mujeres tratadas por lesiones escamosas intraepiteliales (SIL) de cuello uterino. MATERIAL Y MÉTODO: Estudio descriptivo de corte transverso de una serie de casos, en donde se incluyeron 122 mujeres tratadas, 79 (65%) por SIL de bajo grado (LSIL) y 43 (35%) por SIL de alto grado (HSIL) que concurrieron al Laboratorio de HPV del Instituto de Investigaciones en Ciencias de la Salud, Universidad Nacional de Asunción, para realizarse un control post-tratamiento, periodo 2006/2010. RESULTADOS: Se observó un total del 28% (34/122) de mujeres tratadas por SIL positivas para HR-HPV, detectándose infección viral en un 20% de las mujeres con ausencia de SIL (NSIL) (22/108), 83% de las mujeres con LSIL (10/12) y 100% de las mujeres con HSIL (2/2). De las 34 mujeres positivas para HR-HPV, 10 mujeres (29%) presentaron valores altos (100 pg/mL o más) de carga viral relativa, detectándose un aumento de casos positivos con la severidad de la lesión (28% NSIL, 30% LSIL, 50% HSIL). CONCLUSION: La detección de HR-HPV por CH II(r), así como los valores de carga viral relativa altos, en especial en mujeres con NSIL podrían ayudar a identificar mujeres tratadas con riesgo a desarrollar recidivas, contribuyendo así a fortalecer el programa de prevención de cáncer de cuello uterino. .

OBJECTIVE: To determinate the frequency of high risk human papillomavirus (HR-HPV) by hybrid capture II (r) (CH II(r)), according cytology results in women treated for squamous intraepithelial lesions of the cervix (SIL). MATERIAL AND METHODS: A descriptive cross-sectional study of a series of cases that included 122 women treated, 79 (75%) for low grade SIL (LSIL) and 43 (35%) for high grade SIL (HSIL) attending at the HPV Laboratory at the Health Sciences Research Institute (IICS), National University of Asunción (UNA), for post-treatment control during period 2006/2010. RESULTS: A total of 28% (34/122) of women treated for SIL were positive for HR-HPV, detecting viral infection in 20% of women with no SIL (NSIL) (22/108), in 83% of women with LSIL (10/12) and in 100% of women with HSIL (2/2). Of 34 women positive for HR-HPV, 10 women (29%) had high values (100 pg / mL or more) of relative viral load, detecting an increase of positive cases with severity of the lesion (28% NSIL, 30% LSIL, 50% HSIL). CONCLUSION: HR-HPV detection by CH II(r) and high relative viral load values especially in women with NSIL could help to identify treated women at risk of developing recurrence, thereby contributing to strengthening the cervical cancer prevention program. .
