The association between oral health and nutritional status in older adults: a cross-sectional study.

OBJECTIVES: This work aimed to describe the nutritional status of French older adults (age ≥ 90 years) and studied the association between oral health and nutritional status. METHODS: A cross-sectional study was carried out in 2014 among the participants of a cohort on cerebral and functional aging in France at their 25-year follow up (the PAQUID cohort). Nutritional status (Mini Nutritional Assessment [MNA]) and oral health status (number of decayed, missing, and filled teeth [DMFT], number of posterior occluding pairs, xerostomia [Xerostomia Inventory], and prosthetic rehabilitation) were recorded at the participants' living places by two dentists. Univariate and multivariate logistic regressions were used to explore the association between oral health and nutritional status, with adjustments for potential confounders. Odds ratios (OR) were estimated with their 95% confidence interval (CI). RESULTS: 87 participants were included in the analyses: 74.7% were females and the mean age was 94.1 years (± 3.0). Malnutrition or risk of malnutrition (MNA < 24) was present in 23 participants (26.4%), with only one having malnutrition. The mean DMFT score was 26.5 (± 5.3). The mean number of posterior occluding pairs was 1.5 (± 2.3). Twenty-one participants had xerostomia (24.1%). Only 8.1% of the participants had all their teeth or adequate dentures; 47.1% had inadequate dentures, while 44.8% had no dentures despite tooth loss. After adjustment, xerostomia (OR = 8.79; 95% CI = 2.38-39.10; p = 0.002) was found to be associated with malnutrition or risk of malnutrition. CONCLUSION: Being at risk of malnutrition was common among people ≥ 90 years old and was associated with xerostomia. NCT04065828.

The effects of periodontal treatment on diabetic patients: The DIAPERIO randomized controlled trial.

AIM: To assess whether periodontal treatment can lead to clinical, glycaemic control and quality of life improvements in metabolically unbalanced diabetic patients (type 1 or type 2) diagnosed with periodontitis. METHODS: In this open-labelled randomized controlled trial, diabetic subjects (n = 91) were given "immediate" or "delayed" periodontal treatment (full-mouth non-surgical scaling and root planing, systemic antibiotics, and oral health instructions). The main outcome was the effect on glycated haemoglobin (HbA1C ) and fructosamine levels. The General Oral Health Assessment Index and the SF-36 index were used to assess quality of life (QoL). RESULTS: Periodontal health significantly improved after periodontal treatment (p < 0.001). Periodontal treatment seemed to be safe but had no significant effects on glycaemic control based on HbA1C (adjusted mean difference with a 95% confidence interval (aMD) of 0.04 [-0.16;0.24]) and fructosamine levels (aMD 5.0 [-10.2;20.2]). There was no obvious evidence of improvement in general QoL after periodontal treatment. However, there was significant improvement in oral health-related QoL (aMD 7.0 [2.4;11.6], p = 0.003). CONCLUSION: Although periodontal treatment showed no clinical effect on glycaemic control in this trial, important data were provided to support periodontal care among diabetic patients. Periodontal treatment is safe and improves oral health-related QoL in patients living with diabetes. ISRCTN15334496.

Oral health and HIV infection among female sex workers in Abidjan, Côte d'Ivoire.

BACKGROUND: Worldwide, female sex workers (FSW) represent a vulnerable population for oral diseases due to many risk factors including HIV infection and drug abuse. In sub-Saharan Africa, little is known about the burden of oral diseases and their determinants in vulnerable populations. The aim of the study was to estimate the prevalence and associated factors of oral diseases among FSW. METHODS: A cross sectional study was conducted among FSW who attended a dedicated non-profit clinic in Abidjan, Côte d'Ivoire from June to August 2013. Data about the presence of dental caries, periodontitis and oral-mucosal lesions were collected by a dentist during an oral examination. Behavioural information related to oral hygiene habits as well as tobacco and alcohol consumption were collected through a standardized questionnaire. Information related to HIV infection including HIV diagnosis, last known CD4 count and antiretroviral therapy were documented through a medical chart review. Logistic regression models were used to identify factors associated with oral diseases. RESULTS: A total of 249 FSW with a median age of 29 years, [Inter Quartile Range (IQR) = 23-36] and a median duration of sex work of 24 months [IQR 9-60]) were included. Current tobacco use and hazardous alcohol use were reported in 21.7 % and 19.7 % of FSW, respectively. The estimated prevalence of HIV infection was 33.7 % [95 % confidence interval (CI); 27.8 - 39.6]) and 82.1 % of HIV-infected FSW were on antiretroviral therapy . The prevalence of dental caries, periodontitis and oral-mucosal lesions were 62.3 % [95 % CI 55.5 - 67.5], 14.5 % [95 % CI 10.2 - 18.9] and 8.2 % [95 % CI 4.8 - 11.5], respectively. In multivariate analysis, periodontitis, oral-mucosal lesions and HIV infection were associated with odds ratio of 2.6 [95 % CI, 1.2-5.8]) and 50.0 [95 % CI; 6.4-384.6]. CONCLUSIONS: This study showed a high prevalence of oral diseases among FSW in Abidjan. HIV infection was common and significantly associated with periodontal diseases and oral-mucosal lesions. There is a need to integrate regular screening and treatment of oral lesions into the medical follow-up of FSW along with strategies for HIV prevention.

Oral lesions among HIV-infected children on antiretroviral treatment in West Africa.

OBJECTIVE: To estimate the prevalence of oral mucosal diseases and dental caries among HIV-infected children receiving antiretroviral treatment (ART) in West Africa and to identify the factors associated with the prevalence of oral mucosal lesions. METHODS: Multicentre cross-sectional survey in five paediatric HIV clinics in Côte d'Ivoire, Mali and Sénégal. A standardised examination was performed by trained dentists on a random sample of HIV-infected children aged 5-15 years receiving ART. The prevalence of oral and dental lesions and mean number of decayed, missing/extracted and filled teeth (DMFdefT) in temporary and permanent dentition were estimated with their 95% confidence interval (95% CI). We used logistic regression to explore the association between children's characteristics and the prevalence of oral mucosal lesions, expressed as prevalence odds ratio (POR). RESULTS: The median age of the 420 children (47% females) enrolled was 10.4 years [interquartile range (IQR) = 8.3-12.6]. The median duration on ART was 4.6 years (IQR = 2.6-6.2); 84 (20.0%) had CD4 count<350 cells/mm(3). A total of 35 children (8.3%; 95% CI: 6.1-11.1) exhibited 42 oral mucosal lesions (24 were candidiasis); 86.0% (95% CI = 82.6-89.3) of children had DMFdefT ≥ 1. The presence of oral mucosal lesions was independently associated with CD4 count < 350 cells/mm(3) (POR = 2.96, 95% CI = 1.06-4.36) and poor oral hygiene (POR = 2.69, 95% CI = 1.07-6.76). CONCLUSIONS: Oral mucosal lesions still occur in HIV-infected African children despite ART, but rarely. However, dental caries were common and severe in this population, reflecting the need to include oral health in the comprehensive care of HIV.

Modified renal function in pregnancy: impact on emtricitabine pharmacokinetics.

AIMS: The aims were to describe emtricitabine (FTC) pharmacokinetics in a large population of pregnant women during the different trimesters of pregnancy, and to explain FTC pharmacokinetic variability during pregnancy. METHODS: FTC plasma concentrations were measured in 103 non-pregnant and 83 pregnant women, including women in the different trimesters of pregnancy and on the day of delivery. A total of 457 plasma concentrations were available for analysis. A population pharmacokinetic model was developed with Monolix 4.1.3. RESULTS: FTC pharmacokinetics was best described by a two compartment model. The effect of creatinine clearance on apparent elimination clearance (CL/F) was significant. CL/F in pregnant women was significantly higher compared with non-pregnant women (geometric mean 24.1 vs 20.5 l h(-1) , P < 0.001), reflecting a modified renal function. FTC daily exposures (AUC) during pregnancy were lower than AUC in non-pregnant women, regardless of the trimester of pregnancy. FTC AUC geometric means were 8.38 mg l(-1 ) h in the second trimester of pregnancy, 8.16 mg l(-1 ) h in the third trimester of pregnancy, 8.30 mg l(-1 ) h on the day of delivery and 9.77 mg l(-1 ) h in non-pregnant women. FTC concentrations 24 h after administration were lower in pregnant women compared with non-pregnant women (0.054 vs. 0.079 mg l(-1) , P < 0.001) but still above the inhibitory concentration 50%. CONCLUSIONS: FTC CL/F was increased by 18% during pregnancy, reflecting a modified renal function with 50% increase in estimated glomerular filtration rate. However, the impact of this modified renal function on FTC pharmacokinetics was not sufficiently large to consider dose adjustments during pregnancy.

Frequency of barodontalgia among military or civilian pilots and aircrew members.

BACKGROUND: Barodontalgia is dental pain triggered by a change in barometric pressure and can be severe enough to cause in-flight incapacitation. There is a large variation of in-flight barodontalgia incidence in the literature and most of the current epidemiological data on barodontalgia has been compiled from military aircrew. The aim of this study was to evaluate the frequency of barodontalgia in French military and civilian aircrew. METHODS: A cross-sectional study was conducted in 2010. The pilots and crewmembers attending 10 medical units of the French Air Force and Navy, and 5 dedicated to civilian pilots and aircrew were given a standardized and anonymous questionnaire to complete regarding demographic and professional characteristics as well as their barodontalgia. RESULTS: Out of the 1475 questionnaires distributed, 1184 responded (response rate of 80.3%), and 6.6% of these participants (N = 74) reported at least one event of barodontalgia during their career (95% CI: 5.1-8.1%); 43 (6.8%) from the air force and 31 (6.5%) from a civilian service. Median pain intensity during barodontalgia was evaluated at 5.5 out of 10. Pain appeared most commonly during descent (47.3%) and was more frequent below 8000 m. In 10 cases (13.5%), the pilots reported that barodontalgia could have compromised flight security. DISCUSSION: Despite the improvement of aeronautical equipment and the quality of dental care, barodontalgias were still present in 2010 in the French military and in civilian aircrews. We recommend prevention programs be established in order to minimize the frequency of barodontalgias and their potential repercussions on flight safety.

Efficacy of a new membrane obturator prosthesis in terms of speech, swallowing, and the quality of life of patients with acquired soft palate defects: study protocol of the VELOMEMBRANE randomized crossover trial.

BACKGROUND: Soft palate defects created during oral cancer surgery may prevent complete palatal closure and trigger palatopharyngeal insufficiency. One current treatment employs a rigid obturator prosthesis; an extension of acrylic resin at the level of the hard palate ensures surface contact with the remaining musculature. Unfortunately, airflow escape often causes hypernasality, compromises speech intelligibility, and creates swallowing problems (including leakage of food and fluid into the nasal airway). We plan to test a new removable denture featuring a thick dental dam that serves as a membrane obturator. The principal objective of the clinical trial is a comparison of speech handicap levels after 1 month in patients with acquired velar insufficiencies who wear either the new device or a conventional, rigid obturator. The secondary objectives are between-device comparisons of the swallowing handicaps and the health-related qualities of life. METHODS: The VELOMEMBRANE trial is a superiority, open-labeled, two-way, random crossover clinical trial. Adult patients exhibiting velar or palatovelar substance loss after tumor excision and who are indicated for rigid obturator-mediated prosthetic rehabilitation will be recruited in two teaching hospitals in France. Fourteen participants will be randomly allocated to wear both prostheses for 1-month periods in either order. The new membrane obturator is a removable resin prosthesis incorporating a rigid extension that holds a dental dam to restore the soft palate. The primary outcome will be the extent of phonation-related disability (the overall score on the Voice Handicap Index [VHI]). The secondary outcomes will be the Deglutition Handicap Index and health-related quality of life scores of the European Organization for Research and Treatment of Cancer (EORTC). DISCUSSION: High-quality evidence will be provided to document the utility of a new medical device that may greatly improve the management and quality of life of patients with acquired velar insufficiency.

Population pharmacokinetics of nevirapine in HIV-1-infected pregnant women and their neonates.

The aim of the present study was to describe the nevirapine (NVP) pharmacokinetics (PK) in pregnant women and their neonates and to evaluate the transplacental drug transfer and administration scheme for the prevention of mother-to-child transmission. Thirty-eight HIV-1-infected pregnant women were administered one tablet of NVP (200 mg) and two tablets of tenofovir-emtricitabine (Truvada) at the initiation of labor. Children were given NVP syrup (2 mg/kg of body weight) as a single dose (sdNVP) on the first day of life. By pair, NVP concentrations were measured in 11 maternal, 1 cord blood, and 2 neonatal plasma samples and analyzed by a population approach. A one-compartment model was used for mothers and neonates; the absorption rate constants for mothers and neonates were 0.95 h(-1) (intersubject variability, 111%) and 0.39 h(-1), respectively; the apparent elimination clearances were 1.42 liter·h(-1) (intersubject variability, 22%) and 0.035 liter·h(-1), respectively; and apparent volumes of distribution were 87.3 liters (intersubject variability, 25%) and 5.65 liters, respectively. An effect compartment was linked to maternal circulation by mother-to-cord and cord-to-mother rate constants of 1.10 h(-1) and 1.43 h(-1), respectively. Placental transfer, expressed as the fetal-to-maternal area under the curve ratio, was 75%. Neonates had a very long half-lives (110 h) compared to adults. In the 38 mothers, the simulated median individual predicted time during which the NVP concentration remained above the half-maximal inhibitory concentration (IC(50)) was 13.2 days (range, 12 to 19.2 days). Thus, the administration of tenofovir-emtricitabine for at least 3 weeks after delivery should be considered to prevent the emergence of resistant viruses. The neonate must receive sdNVP immediately after birth when the infant is born less than 30 min after maternal drug intake to keep NVP concentrations above the IC(50).

Concentrations of tenofovir and emtricitabine in breast milk of HIV-1-infected women in Abidjan, Cote d'Ivoire, in the ANRS 12109 TEmAA Study, Step 2.

The aim was to evaluate emtricitabine (FTC) and tenofovir (TFV) neonatal ingestion through breast milk. Median TFV and FTC breast milk doses represented 0.03% and 2%, respectively, of the proposed oral infant doses. Neonatal simulated plasma concentrations were extremely low for TFV but between the half-maximal inhibitory concentration and the adult minimal expected concentration for FTC. The rare children who will acquire HIV despite TDF-FTC therapy will need to be monitored for viral resistance acquisition.

Very high concentrations of active intracellular phosphorylated emtricitabine in neonates (ANRS 12109 trial, step 2).

Our objective was to investigate neonatal emtricitabine (FTC) plasma and intracellular pharmacokinetics. The study was designed as a phase I/II prospective trial in two sequential steps evaluating the combination of tenofovir disoproxil fumarate (TDF) and FTC for the prevention of mother-to-child-transmission (PMTCT) of HIV. HIV-1-infected pregnant women received two tablets of TDF (300 mg) and FTC (200 mg) at onset of labor and then one tablet daily for 7 days postpartum. Based on the data obtained in the first part of the Tenofovir/Emtricitabine in Africa and Asia (TEmAA) Study, single doses of 2 mg/kg of FTC and 13 mg/kg of TDF were given to the neonates within 12 h after birth. A total of 540 FTC plasma concentrations and 44 active intracellular phosphorylated metabolite FTC-TP concentrations were taken from the 36 enrolled women and their neonates. Concentrations were measured by the liquid chromatography-tandem mass spectrometry (LC-MS/MS) method and analyzed by a population approach. The proposed dose obtained by simulations based on plasma drug concentrations was confirmed. However, median FTC-TP exposures were, respectively, 5.9 and 6.8 times higher in the fetus and the neonate than in the adult. High FTC-TP concentrations were observed in the four children who had serious adverse events (SAEs), but the link between FTC-TP concentrations and SAEs in children was not formally identified. The exposure to the active form of FTC was high in neonates despite plasma drug concentrations equivalent to those in adults. Our results are similar to those obtained with zidovudine or lamivudine.

Plasma and intracellular tenofovir pharmacokinetics in the neonate (ANRS 12109 trial, step 2).

The objective of this study was to investigate for the first time tenofovir (TFV) pharmacokinetics in plasma and peripheral blood mononuclear cells (PBMCs) of the neonate. HIV-1-infected pregnant women received two tablets of tenofovir disoproxil fumarate (TDF; 300 mg) and emtricitabine (FTC; 200 mg) at onset of labor and then one tablet daily for 7 days postpartum. A single dose of 13 mg/kg of body weight of TDF was administered to 36 neonates within 12 h of life after the HIV-1-infected mothers had been administered two tablets of TDF-emtricitabine at delivery. A total of 626 samples collected within the 2 days after the drug administration were measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and analyzed by a population approach. In the neonate, the median TFV plasma area under the curve and minimal and maximal concentrations, respectively, were 3.73 mg/liter · h and 0.076 and 0.29 mg/liter. In PBMCs, TFV concentrations were detectable in all fetuses, whereas tenofovir diphosphate (TFV-DP) was quantifiable in only two fetuses, suggesting a lag in appearance of TFV-DP. The median TFV-DP neonatal concentration was 146 fmol/106 cells (interquartile range [IQR], 53 to 430 fmol/106 cells); two neonates had very high TFV-DP concentrations (1,530 and 2963 fmol/106 cells). The 13-mg/kg TDF dose given to neonates produced plasma TFV and intracellular active TFV-DP concentrations similar to those in adults. This dose should be given immediately after birth to reduce the delay before the active compound TFV-DP appears in cells.

24-Month Clinical, Immuno-Virological Outcomes, and HIV Status Disclosure in Adolescents Living With Perinatally-Acquired HIV in the IeDEA-COHADO Cohort in Togo and Côte d'Ivoire, 2015-2017.

Background: Adolescents living with perinatally-acquired HIV (APHIV) face challenges including HIV serostatus disclosure. We assessed their 24-month outcomes in relation to the disclosure of their own HIV serostatus. Methods: Nested within the International epidemiologic Database to Evaluate AIDS pediatric West African prospective cohort (IeDEA pWADA), the COHADO cohort included antiretroviral (ART)-treated APHIV aged 10-19 years, enrolled in HIV care before the age of 10 years, in Abidjan (Côte d'Ivoire) and Lomé (Togo) in 2015. We measured the HIV serostatus disclosure at baseline and after 24 months and analyzed its association with a favorable combined 24-month outcome using logistic regression. The 24-month combined clinical immuno-virological outcome was defined as unfavorable when either death, loss to follow-up, progression to WHO-AIDS stage, a decrease of CD4 count >10% compared to baseline, or a detectable viral load (VL > 50 copies/mL) occurred at 24 months. Results: Overall, 209 APHIV were included (51.6% = Abidjan, 54.5% = females). At inclusion, the median CD4 cell count was 521/mm 3 [IQR (281-757)]; 29.6% had a VL measurement, of whom, 3.2% were virologically suppressed. APHIV were younger in Lomé {median age: 12 years [interquartile range (IQR): 11-15]} compared to Abidjan [14 years (IQR: 12-15, p = 0.01)]. Full HIV-disclosure increased from 41.6% at inclusion to 74.1% after 24 months. After 24 months of follow-up, six (2.9%) died, eight (3.8%) were lost to follow-up, and four (1.9%) were transferred out. Overall, 73.7% did not progress to the WHO-AIDS stage, and 62.7% had a CD4 count above (±10%) of the baseline value (48.6% in Abidjan vs. 69.0% in Lomé, p < 0.001). Among the 83.7% with VL measurement, 48.8% were virologically suppressed (Abidjan: 45.4%, Lomé: 52.5%, p <0.01). The 24-month combined outcome was favorable for 45% (29.6% in Abidjan and 61.4% in Lomé, p < 0.01). Adjusted for baseline variables, the 24-month outcome was worse in Lomé in those who had been disclosed for >2 years compared to those who had not been disclosed to [aOR = 0.21, 95% CI (0.05-0.84), p = 0.03]. Conclusions: The frequency of HIV-disclosure improved over time and differed across countries but remained low among West African APHIV. Overall, the 24-month outcomes were poor. Disclosure before the study was a marker of a poor 24-month outcome in Lomé. Context-specific responses are urgently needed to improve adolescent care and reach the UNAIDS 90% target of virological success.

Universal antiretroviral therapy for pregnant and breast-feeding HIV-1-infected women: towards the elimination of mother-to-child transmission of HIV-1 in resource-limited settings.

Prevention of mother-to-child transmission (MTCT) of human immunodeficiency virus type 1 (HIV-1) remains a challenge in most resource-limited settings, particularly in Africa. Single-dose and short-course antiretroviral (ARV) regimens are only partially effective and have failed to achieve wide coverage despite their apparent simplicity. More potent ARV combinations are restricted to pregnant women who need treatment for themselves and are also infrequently used. Furthermore, postnatal transmission via breast-feeding is a serious additional threat. Modifications of infant feeding practices aim to reduce HIV-1 transmission through breast milk; replacement feeding is neither affordable nor safe for the majority of African women, and early breast-feeding cessation (eg, prior to 6 months of life) requires substantial care and nutritional counseling to be practiced safely. The recent roll out of ARV treatment has changed the paradigm of prevention of MTCT. To date, postnatal ARV interventions that have been evaluated target either maternal ARV treatment to selected breast-feeding women, with good efficacy, or single-drug postexposure prophylaxis for short periods of time to their neonates, with a partial efficacy and at the expense of acquisition of drug-related viral resistance. We hypothesize that a viable solution to eliminate pediatric AIDS lies in the universal provision of fully suppressive ARV regimens to all HIV-1-infected women through pregnancy, delivery, and the entire breast-feeding period. On the basis of available evidence, we suggest translating into practice the recently available evidence on this matter without any further delay.

Population pharmacokinetics of emtricitabine in human immunodeficiency virus type 1-infected pregnant women and their neonates.

The objectives of this study were to evaluate emtricitabine (FTC) pharmacokinetics in pregnant women and their neonates and to determine the optimal prophylactic dose for neonates after birth to prevent mother-to-child transmission of human immunodeficiency virus (HIV). A total of 38 HIV-infected pregnant women were administered tenofovir disoproxyl fumarate (300 mg)-FTC (200 mg) tablets-two tablets at the initiation of labor and one daily for 7 days postpartum. By pair, 11 maternal, one cord blood, and two neonatal FTC concentrations were measured using a high-performance liquid chromatography-tandem mass spectrometry validated method and analyzed by a population approach. Model and mean estimates (interpatient variability) were a two-compartment model for mothers, with an absorption rate constant of 0.54 h(-1) (61%), apparent elimination and intercompartmental clearances of 23.2 (17%) and 6.04 liters x h(-1), and apparent central and peripheral volumes of 127 and 237 liters, respectively; an effect compartment linked to maternal circulation for cord blood and a neonatal compartment disconnected, after delivery, with a 10.6-h half-life (30%). After the 400-mg FTC administration, the median population area under the concentration-time curve and the minimal and maximal plasma FTC concentrations in pregnant women were 14.3 mg x liter(-1) x h and 1.68 and 0.076 mg/liter, respectively. At delivery, median (range) predicted maternal and cord blood FTC concentrations were, respectively, 1.16 (0.14 to 1.99) and 0.72 (0.05 to 1.19) mg x liter(-1). We concluded that the 400-mg FTC administration in pregnant women produces higher exposition than does the 200-mg administration in other adults, at steady state. FTC was shown to have good placental transfer (80%). Administering 1 mg FTC/kg as soon as possible after birth or 2 mg/kg 12 h after birth should produce neonatal concentrations comparable to the concentrations observed in adults.

Correlates of adherence to antiretroviral therapy in HIV-infected children in Lomé, Togo, West Africa.

We assessed pediatric adherence to antiretroviral therapy (ART) and examined associated factors among children in Togo, West Africa. Structured interviews of caregivers of consecutively enrolled HIV-infected children receiving ART in three HIV/AIDS care centers in Lome, Togo were conducted. Child perfect adherence reflected caregivers' report of no antiretroviral drug doses missed neither in the past 4 days nor in the month before the interview. A total of 74 ART-treated children were included (median age 6 years). Of these, 42% of caregivers declared perfect adherence. In univariate analyses, the major factors relating to child non-adherence were: being female, living in an individual setting (vs. compound with enlarged family), receiving other ART than an NNRT-based regimen, drug regimens with six pills/spoons or more per day, caregiver other than biological parent, caregiver not declaring HIV-status, not participating to support groups and having perceived difficulty of antiretroviral (ARV) administration. In multivariate analysis, female gender, living in an individual setting, receiving other than NNRTI-based regimen and caregivers' perceived difficulty of ARV administration remained independently associated with the reported child's non-adherence. These data show low rates of perfect adherence to ART in children in West Africa, influenced by child and caregiver characteristics and suggest a need for counseling and education interventions as well as continuous psychological and social support.

The effect of periodontal treatment on patients with rheumatoid arthritis: The ESPERA randomised controlled trial.

OBJECTIVES: To assess the effect of periodontal treatment on clinical and biochemical parameters of rheumatoid arthritis (RA) and quality of life (QoL) in patients with moderately active RA who were diagnosed with periodontitis. METHODS: In this open-label randomised controlled trial, RA subjects (n = 22) were allocated to "immediate" or "delayed" periodontal treatment (full-mouth non-surgical scaling and root planing, systemic antibiotics, and oral hygiene instructions). The main outcome was the 3-month change on the Disease Activity Score 28 based on the Erythrocyte Sedimentation Rate (DAS28-ESR). The Health Assessment Questionnaire and the General Oral Health Assessment Index were used to assess general and oral health QoL, respectively. RESULTS: Periodontal health significantly improved after periodontal treatment (P = 0.03). Periodontal treatment appeared to be safe but led to no significant effects on the DAS28-ESR (adjusted mean difference with 95% confidence interval (aMD) of -0.03 [-0.98; 0.92]). There was no evidence of improvement in the general QoL after periodontal treatment and no significant effect was found for the oral health QoL, despite a positive trend in the "psychological impacts" domain (aMD of 0.13 [-0.07; 0.33], P = 0.20). CONCLUSIONS: Although no clinical effect of periodontal treatment on RA was identified, this trial provides important data to support periodontal care in RA patients. Periodontal treatment is safe and reduces oral inflammation with a possible effect on oral health QoL. Since both periodontitis and RA are complex and multifactorial chronic diseases, it is likely that patient-centred approaches involving both oral health professionals and rheumatologists will contribute to optimal patient care.

Models of support for disclosure of HIV status to HIV-infected children and adolescents in resource-limited settings.

INTRODUCTION: Disclosure of HIV status to HIV-infected children and adolescents is a major care challenge. We describe current site characteristics related to disclosure of HIV status in resource-limited paediatric HIV care settings within the International Epidemiology Databases to Evaluate AIDS (IeDEA) consortium. METHODS: An online site assessment survey was conducted across the paediatric HIV care sites within six global regions of IeDEA. A standardized questionnaire was administered to the sites through the REDCap platform. RESULTS: From June 2014 to March 2015, all 180 sites of the IeDEA consortium in 31 countries completed the online survey: 57% were urban, 43% were health centres and 86% were integrated clinics (serving both adults and children). Almost all the sites (98%) reported offering disclosure counselling services. Disclosure counselling was most often provided by counsellors (87% of sites), but also by nurses (77%), physicians (74%), social workers (68%), or other clinicians (65%). It was offered to both caregivers and children in 92% of 177 sites with disclosure counselling. Disclosure resources and procedures varied across geographical regions. Most sites in each region reported performing staff members' training on disclosure (72% to 96% of sites per region), routinely collecting HIV disclosure status (50% to 91%) and involving caregivers in the disclosure process (71% to 100%). A disclosure protocol was available in 14% to 71% of sites. Among the 143 sites (79%) routinely collecting disclosure status process, the main collection method was by asking the caregiver or child (85%) about the child's knowledge of his/her HIV status. Frequency of disclosure status assessment was every three months in 63% of the sites, and 71% stored disclosure status data electronically. CONCLUSION: The majority of the sites reported offering disclosure counselling services, but educational and social support resources and capacities for data collection varied across regions. Paediatric HIV care sites worldwide still need specific staff members' training on disclosure, development and implementation of guidelines for HIV disclosure, and standardized data collection on this key issue to ensure the long-term health and wellbeing of HIV-infected youth.

Metabolic risk factors in young adults infected with HIV since childhood compared with the general population.

AIM: Metabolic risk factors are poorly documented for the first generation of young adults who have lived with HIV since childhood. We compared their metabolic profile with that of adults of same age from the general population. METHODS: We conducted a cross-sectional analysis of data from two populations: (1) COVERTE (ANRS-CO19), a French national cohort of 18 to 30-year-old patients HIV-infected since childhood, and (2) ENNS, a national cross-sectional population-based household survey on nutrition. Body mass index (BMI), blood pressure, waist circumference, fasting glucose, triglycerides, and HDL-, LDL- and total cholesterol were measured in both studies. Direct standardization on overweight and education level and logistic regression were used to compare the prevalence of metabolic abnormalities between the two populations. RESULTS: Data from 268 patients from COVERTE and 245 subjects from ENNS were analyzed. Tobacco use was similar in both groups. HIV-infected patients had increased mean waist-to-hip ratio and triglycerides to HDL-cholesterol ratio and decreased mean HDL-cholesterol as compared to their counterparts from the general population in both genders. In HIV-infected patients, metabolic syndrome was identified in 13.2% of men (95% confidence interval [CI]: 7.1-19.2) and 10.4% (95% CI: 5.4-15.3) of women versus 10.6% (95%CI: 1.5-19.7) and 1.7% (95%CI: 0-4.1) in subjects from the general population, respectively. CONCLUSION: Young adults infected with HIV since childhood had a higher prevalence of dyslipidemia and metabolically detrimental fat distribution than adults of same age of the general population, supporting close monitoring for cardiometabolic diseases.

Prevalence of resistance to nevirapine in mothers and children after single-dose exposure to prevent vertical transmission of HIV-1: a meta-analysis.

BACKGROUND: Single-dose nevirapine (NVP) is the main option for the prevention of mother-to-child transmission (PMTCT) of HIV-1 in countries with limited resources. However, the use of single-dose NVP results in HIV-1 viral resistance which could compromise the success of subsequent treatment of mother and child with antiretroviral combinations that include non-nucleosidic-reverse-transcriptase inhibitors. This systematic review and meta-analysis of summarized data aimed to estimate the proportion of mothers and children with NVP resistance mutations detected in plasma samples 4-8 weeks postpartum after single-dose NVP use for PMTCT. METHODS: Systematic search of electronic databases (MEDLINE, PASCAL) and conference proceedings (1997 to February 2006). Inclusion of all studies, without design, place or language restrictions, meeting the following criteria: use of single-dose NVP; viral genotyping performed with standard sequence analyses, between 4 and 8 weeks postpartum, in plasma samples; available public report; report of mothers' median baseline plasma HIV-1 RNA levels. Data extraction by two independent reviewers using a standardized form created for this purpose. Logistic random effect models to obtain pooled estimates. Univariable and multivariable meta-regression to explore sources of heterogeneity. RESULTS: The pooled estimate of NVP resistance prevalence was 35.7% [95% confidence interval (CI) 23.0-50.6] in women in 10 study arms using single-dose NVP +/- other antepartum antiretrovirals and 4.5% (CI 2.1-9.4) in three study arms providing also postpartum antiretrovirals (adjusted odds ratio 0.08; CI 0.04-0.16). The corresponding estimates in children were 52.6% (CI 37.7-67.0) in seven study arms using single-dose NVP only and 16.5% (CI 8.9-28.3) in eight study arms combining single-dose NVP with other antiretrovirals. CONCLUSIONS: Single-dose NVP is widely used for PMTCT in resource-poor settings, but the burden of viral resistance is high in both women and children. It is substantially lower in studies providing additional postpartum antiretrovirals. The clinical implications of these findings should be further investigated.

Efficacy of orally administered prednisolone versus partial endodontic treatment on pain reduction in emergency care of acute irreversible pulpitis of mandibular molars: study protocol for a randomized controlled trial.

BACKGROUND: Irreversible pulpitis is a highly painful inflammatory condition of the dental pulp which represents a common dental emergency. Recommended care is partial endodontic treatment. The dental literature reports major difficulties in achieving adequate analgesia to perform this emergency treatment, especially in the case of mandibular molars. In current practice, short-course, orally administered corticotherapy is used for the management of oral pain of inflammatory origin. The efficacy of intraosseous local steroid injections for irreversible pulpitis in mandibular molars has already been demonstrated but resulted in local comorbidities. Oral administration of short-course prednisolone is simple and safe but its efficacy to manage pain caused by irreversible pulpitis has not yet been demonstrated. This trial aims to evaluate the noninferiority of short-course, orally administered corticotherapy versus partial endodontic treatment for the emergency care of irreversible pulpitis in mandibular molars. METHODS/DESIGN: This study is a noninferiority, open-label, randomized controlled clinical trial conducted at the Bordeaux University Hospital. One hundred and twenty subjects will be randomized in two 1:1 parallel arms: the intervention arm will receive one oral dose of prednisolone (1 mg/kg) during the emergency visit, followed by one morning dose each day for 3 days and the reference arm will receive partial endodontic treatment. Both groups will receive planned complete endodontic treatment 72 h after enrollment. The primary outcome is the proportion of patients with pain intensity below 5 on a Numeric Scale 24 h after the emergency visit. Secondary outcomes include comfort during care, the number of injected anesthetic cartridges when performing complete endodontic treatment, the number of antalgic drugs and the number of patients coming back for consultation after 72 h. DISCUSSION: This randomized trial will assess the ability of short-term corticotherapy to reduce pain in irreversible pulpitis as a simple and rapid alternative to partial endodontic treatment and to enable planning of endodontic treatment in optimal analgesic conditions.
