RESUMEN
Internet is a popular source of information regarding vaccination. This study aimed to determine whether there is a negative association between Internet use among French vaccine-hesitant mothers and HPV vaccine uptake by their daughters, and to gain insight into the pathways that would link Internet use to the lack of HPV vaccine uptake. We conducted a pooled cross-sectional analysis across the 2015, 2016, 2017 and 2018 Vaccinoscopie® Survey. Multivariate logistic regression and path models were used in the analysis. The study sample included a total of 2038 respondent mothers. Of those, 89 (4.4%) declared having never been in the situation of searching for information regarding a vaccination they had hesitated about, leaving 1949 mothers for the present analysis. Approximately 24% (466/1949) of the mothers declared using the Internet as a source of vaccine information. In multivariate logistic regression adjusted for physician recommendation of HPV vaccination, attitudes towards vaccines in general, perception of HPV vaccine usefulness, maternal level of education, region of residence, and the survey year, the use of Internet by the mothers was significantly associated with a lower HPV vaccination among their daughters (adjusted odds ratio (aOR), 0.66; 95% confidence interval (CI), 0.47-0.91). Path analysis further confirmed the negative effect of Internet use (ß = -0.10, standard error (SE) = 0.02, P < 0.0001), highlighting how the Internet plays a detrimental role in HPV vaccine uptake through a lower perceived level of HPV vaccine usefulness, a lower perceived level of information on childhood vaccination, and unfavorable attitudes towards vaccination in general.

BACKGROUND: Lumbar puncture (LP) is an invasive medical procedure that can be done by any doctor. Several simulation-based trainings have been built however the evaluations of the theoretical knowledge and the impact of the simulation-based training have never been performed in real life. The objective was to evaluate the impact of a LP training on the theoretical knowledge improvement and the performance of a LP in clinical practice. METHODS: Before and after medical students' training, theoretical knowledge and confidence level were assessed. Over a 6 months period, the impact of simulation training was evaluated by the success rate of students' first LP carried out in hospitalized patients and compared to the results of a no-training control. RESULTS: Students' theoretical knowledge and confidence level showed significant improvement after simulation training on 115 students (p < 0.0001). The evaluation in real life based on 41 students showed that the success rate of the first LP in patients was higher in the LP simulation group compared to the control group (67% vs 14%, p = 0.0025). The technical assistance was also less frequently needed in the LP simulation group (19% vs 57%, respectively, p = 0.017). The rate of students who participated in this educational study was low. DISCUSSION: Simulation-based teaching was an effective way to improve students' theoretical and practical knowledge. Whether this approach translates to other procedural skills in real clinical settings merits further study. The low participation rate in the study is due to the fact that students are not used to be included in educational studies and to the complexity of evaluation in routine clinical practice.

BACKGROUND: Needle aspiration (NA) is recommended as first-line treatment of primary spontaneous pneumothorax (PSP). We aimed to assess NA success and the effect of a longer symptom onset to NA time. METHODS: A discovery phase was retrospectively conducted in the intensive care unit of Louis Mourier Hospital (January 2000 to December 2011) followed by a prospective validation cohort (January 2012 to August 2015). The primary outcome was immediate NA success defined by the absence of need for chest tube insertion within 24 hours of the procedure. RESULTS: In the discovery phase, 130 patients were admitted for PSP and 98 had NA as first-line treatment (75%). The immediate success rate of NA was 34.7% and was higher when it was performed ≥48 hours after symptom onset (57.7% vs 25%; p=0.004). In the prospective cohort, 87 patients were admitted for PSP; 71 (82%) had NA as first-step treatment. The immediate success rate was 40.8%. NA was more successful when it was performed after 48 hours of symptoms' onset (34.5% vs 7.1%; p=0.005). A delay between the first symptom and NA procedure ≥48 hours was associated with a higher success of NA (OR=13.54; 95% CI 1.37 to 133). A smaller pneumothorax estimated by Light's index was associated with NA success (OR=0.95; 95% CI 0.92 to 0.98). To what extent some of these pneumothoraces would have had a spontaneous resolution remains unknown. CONCLUSION: When managing PSP with NA, a longer symptom onset to NA time was associated with NA success. TRIAL REGISTRATION NUMBER: NCT02528734.

PURPOSE: Sophia Asthme (SA) is a chronic disease management program of the French national health insurance for adult patients with asthma. We evaluated the early impact of this intervention. METHODS: We conducted a matched controlled, before-and-after quasi-experimental study within the French Health Insurance Database (Système National Des Données de Santé [SNDS]). The SA program was implemented in a set of 18 Départements in France and targeted 18- to 44-year-old subjects, with at least two reimbursement dates for asthma drug therapy during the 12-month period prior to program targeting. Change in outcomes was assessed from the "before program" period (January-December 2014) to the "after program implementation" period (March 2015-February 2016) in the program group (eligible to SA program in the 18 Départements) and in the matched controlled group. The main outcome measure was the before-after change in proportion of subjects with a controllers/(controllers+relievers) ratio greater than 50%. RESULTS: Of the 99 578 subjects of the program group, 9225 (9.3%) actually participated in SA program. The program had no significant impact on the proportion of subjects with a ratio greater than 50%. However, subjects exposed to SA program were significantly more likely to be dispensed controller medications (OR = 1.04; 95% CI, 1.01-1.07) and to sustain their use of these medications (OR = 1.08; 95% CI, 1.05-1.12). CONCLUSION: We did not demonstrate any significant impact of the program on the primary outcome. The modest yet encouraging findings of this early evaluation suggest the need for reformulation of the program and its evaluation.

WHAT WE ALREADY KNOW ABOUT THIS TOPIC: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Oropharyngeal care with chlorhexidine to prevent ventilator-associated pneumonia is currently questioned, and exhaustive microbiologic data assessing its efficacy are lacking. The authors therefore aimed to study the effect of chlorhexidine mouthwash on oropharyngeal bacterial growth, to determine chlorhexidine susceptibility of these bacteria, and to measure chlorhexidine salivary concentration after an oropharyngeal care. METHODS: This observational, prospective, single-center study enrolled 30 critically ill patients under mechanical ventilation for over 48 h. Oropharyngeal contamination was assessed by swabbing the gingivobuccal sulcus immediately before applying 0.12% chlorhexidine with soaked swabs, and subsequently at 15, 60, 120, 240, and 360 min after. Bacterial growth and identification were performed, and chlorhexidine minimal inhibitory concentration of recovered pathogens was determined. Saliva was collected in 10 patients, at every timepoint, with an additional timepoint after 30 min, to measure chlorhexidine concentration. RESULTS: Two hundred fifty bacterial samples were analyzed and identified 48 pathogens including Streptococci (27.1%) and Enterobacteriaceae (20.8%). Oropharyngeal contamination before chlorhexidine mouthwash ranged from 10 to 10 colony-forming units (CFU)/ml in the 30 patients (median contamination level: 2.5·10 CFU/ml), and remained between 8·10 (lowest) and 3·10 CFU/ml (highest count) after chlorhexidine exposure. These bacterial counts did not decrease overtime after chlorhexidine mouthwash (each minute increase in time resulted in a multiplication of bacterial count by a coefficient of 1.001, P = 0.83). Viridans group streptococci isolates had the lowest chlorhexidine minimal inhibitory concentration (4 [4 to 8] mg/l); Enterobacteriaceae isolates had the highest ones (32 [16 to 32] mg/l). Chlorhexidine salivary concentration rapidly decreased, reaching 7.6 [1.8 to 31] mg/l as early as 60 min after mouthwash. CONCLUSIONS: Chlorhexidine oropharyngeal care does not seem to reduce bacterial oropharyngeal colonization in critically ill ventilated patients. Variable chlorhexidine minimal inhibitory concentrations along with low chlorhexidine salivary concentrations after mouthwash could explain this ineffectiveness, and thus question the use of chlorhexidine for ventilator-associated pneumonia prevention.

AIM: To evaluate outcomes and post-donation kidney function of older living kidney donors (LKD). METHODS: Retrospective analysis of prospective database including all consecutive LKD undergoing laparoscopic nephrectomy in a single center (09/1998-12/2013). LKD aged ≥60 years were compared to younger LKD. Renal function assessed by creatinine levels and estimated glomerular filtration rates (eGFR). Surgical complications classified according to the Clavien-Dindo classification. Bivariate and multivariate analyses using linear mixed effect models were performed to determine factors (age, gender, hypertension status, BMI, choice of better functioning kidney for donation) that might impinge on renal function after donation. RESULTS: 213 LKD were identified: 49 older (median age: 66 years, range: 60-79) and 164 younger (median age: 46, range: 25-59). Mean operative time (149 vs. 152 min, p = 0.69), conversion to laparotomy (n = 1 vs. 3, p = 0.92), grade III-IV complications (n = 4 vs. 2, p = 0.36) were similar. Older had more grade I-II complications (n = 18 vs. 4, p < 0.001). Despite similar pre-donation eGFR (80 vs. 84 ml/min/1.73 m2), older donors presented significantly lower eGFR during inpatient period (46 vs. 51 ml/min/1.73 m2, p = 0.0003), at 1 month (51 vs. 58 ml/min/1.73 m2, p = 0.002) and at 1 year (54 vs. 62 ml/min/1.73 m2, p = 0.001). Multivariate analysis adjusted to gender, hypertension status, BMI and choice of better functioning kidney for donation showed that at 1 year, age ≥60 affected renal function by a coefficient of 0.91 (p < 0.001). CONCLUSION: Despite renal function improvement after discharge, LKD ≥ 60 years presented lower eGFR than younger at one year and had more grade I-II surgical complications.

OBJECTIVES: Women with SLE are at increased risk of cardiovascular events (CVEs), but a relationship with traditional cardiovascular and SLE-specific risk factors has not been established. In unselected populations, adverse pregnancy outcomes linked to maternal-placental syndrome (MPS) are associated with an increased risk of CVEs. However, the effect of MPS on CVEs is unknown in women with SLE. The aim of this study was to determine if MPS increased the risk and accelerated the development of CVEs in women with SLE. METHODS: Utilizing Swedish population registries, parous women with SLE were identified. Exposures were the following: MPS defined as hypertensive disorders of pregnancy; small-for-gestational-age; placental abruption and stillbirth; and preterm delivery <34 weeks. Outcomes were CVE encompassing cardiovascular morbidity and mortality. Risk of an event was modelled using Cox proportional hazards adjusted for year of delivery, age at CVE, severity of SLE and cardiovascular risk factors. Time-to-CVE was estimated using Kaplan-Meier methods. RESULTS: Over the 38-year study period, there were 3977 women with 7410 pregnancies, of whom 413 (10.2%) suffered a CVE. Hazard of CVE was higher in those with MPS, particularly when MPS (adjusted HR = 1.64; 95% CI: 1.31, 2.05) was combined with preterm delivery < 34 weeks' gestation (adjusted HR 1.99; 95% CI 1.39, 2.84). There was accelerated development of CVEs in women with MPS of 10.5% (vs 7.3% in uncomplicated pregnancies) over the 38-year interval (P < 0.05). CONCLUSION: Pregnancy complicated by MPS and preterm delivery exerts an independent effect to increase the risk and accelerate the development of CVEs in parous women with SLE.

The quality of online health information is cause for concern in general, and the spread of mis/disinformation on the benefits and risks of vaccines has certainly been fueling vaccine hesitancy. In the wake of the COVID-19 pandemic, we have entered an era of unprecedented "infodemic." There has never been a more urgent time to address the long-standing question of how to overcome the deleterious influence of exposure to online mis/disinformation on vaccine uptake. eHealth literacy, a skill set including media literacy, is key to navigating the web in search for health information and processing the one encountered through social media. Studies assessing the impact of increasing eHealth literacy on behavioral attitudes and health outcomes in the general population are relatively scarce to date. Yet for many reasons, leveraging eHealth literacy skills, and more specifically, media literacy, could be of great value to help mitigate the detrimental effects of erroneous information on vaccination decision-making. In this paper, we make the case that eHealth and media literacies should be viewed as fundamental skills that have the potential to empower citizens to better recognize online mis/disinformation and make informed decisions about vaccination as any other health matters.

INTRODUCTION: The uptake of human papillomavirus (HPV) vaccination in France remains low. The aim of this study was to identify factors associated with the uptake of the HPV vaccine in girls aged 11-14 years in France. METHODS: We conducted a telephone survey among a quota sample of 1102 mothers of 11-14-year-old daughters residing in mainland France, using the French Survey Questionnaire for the Determinants of HPV Vaccine Hesitancy (FSQD-HPVH). The dependent variable was the uptake of at least one dose of the HPV vaccine in the daughter. The independent variables included the FSQD-HPVH item variables, the Global Vaccine Confidence Index item variables, the daughter's age, and the mother's socioeconomic status. RESULTS: Overall, 38.6% of the mothers indicated that their daughter received at least one dose of the HPV vaccine. The multivariate analysis revealed that agreeing with the statement that doctors/health care providers believe vaccinating girls against HPV was a good idea, and having asked questions to the attending doctor about HPV vaccines were associated with a higher HPV vaccine uptake (OR = 4.99 , 95% CI [2.09-11.89]; and OR = 3.44, 95% CI [2.40-4.92]). Mother's belief that her daughter was too young to be vaccinated against HPV (OR = 0.16 , 95% CI [0. 09-0.29]) and lower daughter's age (OR = 0.17 , 95% CI [0.10-0.28] for girls aged 11 compared to those aged 14) were found strongly inversely associated with HPV vaccination, followed by agreeing with the statement that the HPV vaccine was unsafe (OR = 0.42 , 95% CI [0.26-0.67]), identifying as true the statement that HPV was very rare (OR = 0.49 , 95% CI [0.31-0.77]), and the mother's refusal of own vaccination (OR = 0.57 , 95% CI [0.40-0.80]). CONCLUSION: We have identified important determinants associated with HPV vaccine uptake in France. Interventions designed to improve HPV vaccine uptake should be tailored to address these determinants.

As the coronavirus disease 2019 (COVID-19) spreads across the world, the rapid distribution of an effective vaccine and its acceptability among the population constitute priorities for health authorities. This study aimed to document attitudes of the general population toward a future vaccine against COVID-19. We used the national COCONEL surveys conducted during the lockdown to identify factors associated with vaccine refusal, in the whole population, and separately among men and women. We investigate the role of socioeconomic and demographic factors as well as exposure to COVID-19. Among the 5,018 participants, 24.0% reported their intention to refuse the vaccine. Thinking this vaccine would not be safe, being against vaccination in general, and perceiving COVID-19 to be harmless were the three main reasons given to explain vaccine refusal. Women were more likely to refuse the vaccine, especially due to a reluctance toward vaccination in general or the perception that a COVID-19 vaccine would not be safe. Some factors associated with the intention to refuse the vaccine were the same among men and women such as a lack of prior vaccination against influenza, and concern over being infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), while others differed slightly according to gender such as age, and high prevalence of COVID-19 in their region of residence. Authorities should therefore guarantee that all the necessary precautions are taken before marketing the vaccine and communicate transparently on the process of its development, and on the coverage rate required to reach herd immunity.Abbreviation: EHI: Equivalized Household Income per month; SARS-CoV-2: Severe acute respiratory syndrome coronavirus 2.

INTRODUCTION: This study aimed to develop and undertake a preliminary validation of a French Survey Questionnaire for the Determinants of HPV Vaccine Hesitancy (FSQD-HPVH). METHODS: We undertook an electronic-based Delphi consultation among a panel of Francophone experts in two rounds. Round 1 consisted of the assessment of a structured questionnaire comprising of three parts ((i) Contextual influences, (ii) Individual and group influences, and (iii) Vaccine/vaccination-specific issues), in line with the WHO Strategic Advisory Group of Experts (SAGE) Vaccine Hesitancy (VH) Model of Determinants. Items included in this questionnaire were based on a literature review. Definitions of the factors included in the SAGE model were provided in the questionnaire. The panel of experts was asked to score each item using a 3-point Likert scale, in which 1 meant "Essential", 2 "Useful but not essential", and 3 "Not necessary". The panel was also invited to comment on the clarity/comprehension of the questions and suggest reformulations/additional items. Lawshe's Content Validity Ratio (CVR) was computed to assess the level of consensus for each statement. Only items upon which agreement was not reached in Round 1 (CVR < 0.6) and newly proposed items were submitted for evaluation in Round 2, using the same procedure. RESULTS: Fifteen experts completed the two rounds. Of 83 items evaluated in Round 1, 35 (42%) had a CVR ≥ 0.6 and were accepted without modification. In Round 2, 66 items were submitted to the same panel and consensus was reached for 22 (33%) items using the threshold of 0.6. The final FSQD-HPVH version includes 57 items. CONCLUSION: This study developed a survey instrument for the evaluation of HPV VH in France with good content validity. It will be used to assess the determinants of HPV VH, the first step towards an evidence-based approach to improving HPV vaccination rates in France.

BACKGROUND: Guidelines for the management of diabetic ketoacidosis (DKA) do not consider the type of underlying diabetes. We aimed to compare the occurrence of metabolic adverse events and the recovery time for DKA according to diabetes type. METHODS: Multicentre retrospective study conducted at five adult intermediate and intensive care units in Paris and its suburbs, France. All patients admitted for DKA between 2013 and 2014 were included. Patients were grouped and compared according to the underlying type of diabetes into three groups: type 1 diabetes, type 2 or secondary diabetes, and DKA as the first presentation of diabetes. Outcomes of interest were the rate of metabolic complications (hypoglycaemia or hypokalaemia) and the recovery time. RESULTS: Of 122 patients, 60 (49.2%) had type 1 diabetes, 28 (22.9%) had type 2 or secondary diabetes and 34 (27.9%) presented with DKA as the first presentation of diabetes (newly diagnosed diabetes). Despite having received lower insulin doses, hypoglycaemia was more frequent in patients with type 1 diabetes (76.9%) than in patients with type 2 or secondary diabetes (50.0%) and in patients with newly diagnosed diabetes (54.6%) (p = 0.026). In contrast, hypokalaemia was more frequent in the latter group (82.4%) than in patients with type 1 diabetes (57.6%) and type 2 or secondary diabetes (51.9%) (p = 0.022). The median recovery times were not significantly different between groups. CONCLUSIONS: Rates of metabolic complications associated with DKA treatment differ significantly according to underlying type of diabetes. Decreasing insulin dose may limit those complications. DKA treatment recommendations should take into account the type of diabetes.
RESUMEN
Europe is increasingly described as the region in the world with the least confidence in vaccination, and particularly in the safety of vaccines. The aim of this systematic literature review was to gather and summarise all peer-reviewed and grey literature published about determinants of Human Papillomavirus (HPV) vaccine hesitancy in Europe. Ten thematic categories were identified across the 103 articles which were included in the review. Participants from European studies most commonly reported issues with the quantity and quality of information available about HPV vaccination; followed by concerns about potential side effects of the vaccine; and mistrust of health authorities, healthcare workers, and new vaccines. Comparative analyses indicated that confidence determinants differed by country and population groups. This evidence supports the need to develop context-specific interventions to improve confidence in HPV vaccination and design community engagement strategies aiming to build public trust.

Anaphylaxis is a systemic acute hypersensitivity reaction that is considered to depend on allergen-specific immunoglobulin E (IgE) antibodies and histamine release by mast cells and basophils. Nevertheless, allergen-specific IgG antibodies have been proposed to contribute when the allergen is an abundant circulating large molecule, e.g., after infusions of therapeutic antibodies or dextran. Data from animal models demonstrate a pathway involving platelet-activating factor (PAF) release by monocytes/macrophages and neutrophils activated via their Fc gamma receptors (FcγRs). We hypothesized that such a pathway may also apply to small drugs and could be responsible for non-IgE-mediated anaphylaxis and influence anaphylaxis severity in humans. We prospectively conducted a multicentric study of 86 patients with suspected anaphylaxis to neuromuscular-blocking agents (NMBAs) during general anesthesia and 86 matched controls. We found that concentrations of anti-NMBA IgG and markers of FcγR activation, PAF release, and neutrophil activation correlated with anaphylaxis severity. Neutrophils underwent degranulation and NETosis early after anaphylaxis onset, and plasma-purified anti-NMBA IgG triggered neutrophil activation ex vivo in the presence of NMBA. Neutrophil activation could also be observed in patients lacking evidence of classical IgE-dependent anaphylaxis. This study supports the existence of an IgG-neutrophil pathway in human NMBA-induced anaphylaxis, which may aggravate anaphylaxis in combination with the IgE pathway or underlie anaphylaxis in the absence of specific IgE. These results reconcile clinical and experimental data on the role of antibody classes in anaphylaxis and could inform diagnostic approaches to NMBA-induced acute hypersensitivity reactions.

INTRODUCTION: This study protocol describes a trial designed to investigate whether high-flow heated and humidified nasal oxygen (HFHO) therapy in patients with hypercapnic acute respiratory failure (ARF) reduces the need of non-invasive ventilation (NIV). METHODS AND ANALYSIS: This is an open-label, superiority, international, parallel-group, multicentre randomised controlled two-arm trial, with an internal feasibility pilot phase. 242 patients with hypercapnic ARF requiring NIV admitted to an intensive care unit, an intermediate care or a respiratory care unit will be randomised in a 1:1 ratio to receive HFHO or standard oxygen in between NIV sessions. Randomisation will be centralised and stratified by centre and pH at admission (pH ≤7.25 or >7.25). The primary outcome will be the number of ventilator-free days (VFDs) and alive at day 28 postrandomisation. The secondary outcomes will encompass parameters related to the VFDs, comfort and tolerance variables, hospital length of stay and mortality. VFDs at 28 days postrandomisation will be compared between the two groups by Wilcoxon-Mann-Whitney two-sample rank-sum test in the intention-to-treat population. A sensitivity analysis will be conducted in the population of patients for whom the criteria of switching from NIV to spontaneous breathing, or conversely, are not strictly verified. ETHICS AND DISSEMINATION: The protocol has been approved by the Comité de Protection des Personnes (CPP) Sud-Ouest & Outre-Mer IV (ref CPP17-049a/2017-A01830-53) and will be carried out in accordance with the Declaration of Helsinki and Good Clinical Practice guidelines. A trial steering committee will oversee the progress of the study. Findings will be disseminated through national and international scientific conferences, and publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03406572.

BACKGROUND: Gastric leak is the most common and dreaded post-operative infectious complication (PIC) after laparoscopic sleeve gastrectomy (LSG). Accurate identification of patients at risk postoperatively is of cardinal importance. OBJECTIVE: The aim of this study is to assess the diagnostic performance of C-reactive protein (CRP) in predicting PICs and the most optimal time to measure it. METHODS: CRP results were collected in patients undergoing LSG between 2011 and 2015. CRP was systematically measured on post-operative days (POD) 1, 3, and 5. RESULTS: Of 1326 patients, 42 (3.2%) developed a PIC at a median of 5 days after surgery. The incidence of leakage was 1.9%. The best area under the curve was observed on POD5 (0.87; 95% CI 0.77-0.96). At this time point, a cut-off of 115 mg/L yielded a sensitivity of 66.7% (95% CI 46.5-86.8%), a specificity of 95.1% (95% CI 93.9-96.3%), a positive and negative predictive values of 19.4% (95% CI 10.3-28.6%) and 99.4% (95% CI 99.0-100%), respectively, and a positive and negative likelihood ratios (LRs) of 13.62 and 0.35, respectively. The combination of sequential assessments of CRP on POD3 and 5 provided a sensitivity of 84.4% (95% CI 71.8-97.0%), a specificity of 91.1% (95% CI 89.5-92.8%), a positive and negative predictive values of 20.9% (95% CI 14.0-27.9%) and 99.5% (95% CI 99.1-99.9%), respectively, and a positive and a negative LRs of 9.58 and 0.17, respectively. CONCLUSIONS: CRP may be useful to identify patients at risk of PICs after LSG and, therefore, to prompt early investigation. However, CRP does not help rule out PICs.

INTRODUCTION: Laparoscopic sleeve gastrectomy (LSG) modifies gastrointestinal substances that control hunger and satiation via the brain-gut axis. A potential mechanism implicated in weight loss is the shift in food preferences. Our aim was to assess changes in taste preferences and their relationship to weight loss. METHODS: This is a prospective longitudinal observational study in 100 consecutive LSG patients. Questionnaire with photographs of tastes was administered before surgery, at postoperative (PO) day 6 and PO month 6. Participants asked to rate each item in terms of desire to consume on a 5-point Likert scale. RESULTS: Preoperative demographics are as follows: 77 women/23 men, mean age 40.8 ± 12 years, and mean BMI 42.46 ± 6.7 kg/m2. Mean 6-month PO % total body weight loss (%TBWL): 24 ± 6.2%. Preferences for bitter, salty, umami, fatty, sour, spicy, and sweet decreased significantly from baseline to PO day 6 (p < 0.001) and to PO month 6 (p < 0.002). Preferences of water (4.22) did not change significantly; red wine (1.8) and cigarettes (1.86) decreased significantly at PO day-6, but returned to baseline range at PO month 6. The highest changes of preferences in 6 months were observed for fatty (delta = 1.58) and sweet (delta = 0.95), (p < 0.002). Preference for salty at 6 months negatively correlated with %TBWL (p = 0.01). CONCLUSION: LSG seems to be associated with a rapid and sustained decrease in preferences for all core tastes, detectable already at PO day 6. Preferences for sweet and fatty food undergo the highest decline, whereas preferences of water, red wine, and cigarette remain unchanged. The decrease in salty preference seems to correlate with 6-month %TBWL. Further studies are needed on the long-term impact of taste changes after LSG.

OBJECTIVE: The implication of human papilloma virus (HPV) in head and neck squamous cell carcinoma (HNSCC) is well established, especially in oropharyngeal SCC. HIV patients have a higher risk of persistent HPV infection. We investigated the role of HPV in HNSCC carcinogenesis in HIV population. DESIGN: Retrospective monocentric study. METHODS: We studied HIV patients who presented with HNSCC between 1994 and 2014. For each patient, tumor characteristics, HIV disease, and survival information were collected. Tumor HPV testing was performed using p16 immunohistochemistry (IHC), in-situ hybridization and PCR. We assessed the percentage of HPV in this population of HIV patients with HNSCC and compared HIV disease characteristics based on HPV status. RESULTS: Forty-seven patients were included: 11 women/36 men, the median age was 50 years. Tumor HPV testing was performed in 40 patients. Tumors were located in oropharynx (32%), oral cavity (32%), larynx (21%), and hypopharynx (11%). At the time of diagnosis, median CD4 level was 385âcells/µl, 31% of the patients were stage (Centers for Disease Control, stage C). The percentage of HPV linked to HNSCC for all locations in HIV patients was 30% (nâ=â12). HPV16 accounted for 50% of all HPV genotypes. HPV positive status was associated with a CD4 nadir of less than 200 (Pâ=â0.026), but not with CD4 level at time of diagnosis (Pâ=â0.414). HPV-negative tumors tend to be associated with poorer 5-year overall survival (hazard ratioâ=â2.9, Pâ=â0.0711). CONCLUSION: HPV plays a critical role in HNSCC development in HIV population. HIV immunodeficiency may increase HPV persistence and progression of HNSCC.
