Residual phenotypic susceptibility to doravirine in multidrug-resistant HIV-1 from subjects enrolled in the PRESTIGIO Registry.

OBJECTIVES: Doravirine shows a rather distinct resistance profile within the nonnucleoside reverse transcriptase inhibitor (NNRTI) class. This study aimed to evaluate the phenotypic susceptibility to doravirine, rilpivirine and etravirine in a panel of multidrug-resistant (MDR) HIV-1 isolates collected from people living with HIV (PLWH) enrolled in the PRESTIGIO Registry. METHODS: Recombinant viruses expressing PLWH-derived protease, reverse transcriptase coding regions were generated from plasma samples at virological failure with documented resistance to protease inhibitors, nucleoside reverse transcriptase inhibitors, NNRTIs and integrase strand transfer inhibitors. In vitro susceptibility was assessed through a phenotypic assay measuring fold-change values with respect to the reference NL4-3 virus. Genotypic susceptibility was computed by the Stanford HIVdb algorithm 8.9-1. RESULTS: Plasma samples were collected from 22 PLWH: 20 (91%) were male, median age 55 years (IQR 50-58), time since HIV-1 diagnosis 27 years (23-31) and time on antiretroviral treatment 23 years (22-26). Median doravirine, etravirine and rilpivirine fold-change values were 9.8 (2.9-40.4), 42.9 (3.1-100.0) and 100.0 (17.9-100.0), respectively. According to the fold-change cut-offs, full susceptibility was observed in five (23%), four (18%) and one (5%) cases with doravirine, etravirine and rilpivirine, respectively. Irrespective of the presence of specific doravirine mutations, higher numbers of NNRTI mutations correlated with higher fold-change values for doravirine. By comparing the distribution of fold-change values with the Stanford HIVdb predicted susceptibility, a significant correlation was detected for doravirine and rilpivirine but not etravirine. CONCLUSION: Despite extensive cross-resistance among NNRTIs, doravirine can be a valid option in a proportion of PLWH with MDR HIV-1. Doravirine activity appeared to be inferred with fair accuracy by the HIVdb algorithm.

Long-acting drugs: people's expectations and physicians' preparedness. Are we readying to manage it? An Italian survey.

To evaluate patients' expectations regarding long-acting antiretroviral agents and preferences about where to receive them. Multicenter cross-sectional survey-based study. Through an online survey, we asked people living with human immunodeficiency virus to judge their relationship with daily antiretroviral therapy (ART) and to give their opinion about long-acting drugs. We also collected data regarding the age of the patients, their site of follow-up, time since the diagnosis, and compliance to ART. Two hundred forty-two patients aged 18 to 79 years were included in the study: 58 (24%) females, 182 (75.2%) males, and 2 (0.8%) male-to-female transgenders. 81.8% of the said population had a good relationship with ART. 33.6% of them consider daily ART an obligation and a restriction to their freedom. One hundred forty-three (59.1%) patients already knew about long-acting drugs before our interview, and 215 (88.8%) patients were interested in it. One hundred fifty-six (64.4%) interviewees said they would still be interested in hospital-available injective long-acting drugs, although 57.9% of the patients would rather receive them at home. The data emerging from our survey reveal that around 90% of the people living with HIV are interested in changing their actual treatment with a long-acting one. Moreover, for the first time to our knowledge, such a high number of patients showed an enthusiastic response to the new opportunity to be treated directly at home. The introduction of these new drugs could be revolutionary and represents an important step toward treatment simplification.

A much needed metric: Defining reliable and statistically meaningful change of the oral version Symbol Digit Modalities Test (SDMT).

BACKGROUND: The Symbol Digit Modalities Test (SDMT) has been recommended for use in clinical trials and outcome studies to monitor cognitive change. However, defining what is a meaningful change has been elusive for several years. OBJECTIVE: The present investigation aimed to develop methods for assessing individual-level statistically significant change on the SDMT - reliable change indices (RCIs) and standardized regression-based (SRB) equations. METHODS: A total of 219 healthy individuals completed the oral version SDMT at baseline, 6-month and 1-year follow-up. RESULTS: The SDMT demonstrated high reliability across all time points (r's = 0.83 to 0.86). Reliable change scores of 7, 8, and 10 points for the 6-month intervals represented statistically meaningful change at the 0.70, 0.80, and 0.90 confidence intervals, respectively. Over 1-year, a difference of 8, 10, and 12 was statistically meaningful at the 0.70, 0.80, and 0.90 confidence intervals, respectively. SRB equations are also provided taking into account additional factors found to be predictive of SDMT scores over time. CONCLUSION: Clinicians frequently denote a decline of 4 points on the SDMT as meaningful. Results in this large normative sample show that higher cut-points are needed to demonstrate statistically significant decline at the individual level. RCIs are provided for 6 month and one year assessment, which is typical in clinical practice and trials. SRB equations are also provided for use when applicable and may provide a more precise assessment of meaningful change.

Tired of not knowing what that fatigue score means? Normative data of the Modified Fatigue Impact Scale (MFIS).

BACKGROUND: The Modified Fatigue Impact Scale (MFIS) is one of the most common self-report measures used to assess fatigue in multiple sclerosis (MS). Despite its widespread use, there are no existing normative data for the MFIS. OBJECTIVE: The present investigation aimed to develop normative data for the MFIS in a large community sample, stratified by age, gender, and education and to compare the derived new cutoffs to an existing cutoff. METHODS: A total of 675 healthy individuals, stratified by age, gender, and education completed the MFIS. After the removal of 19 outliers, the final sample consisted of 656 individuals. Archival data of 540 individuals with MS who completed the MFIS were also included to analyze the utility of the new cutoffs. RESULTS: There were no main effects on the MFIS for gender. However, there were main effects for age and education. Specifically, younger cohorts (25-34 and 35-44) reported less physical fatigue compared to the two oldest cohorts (55-64 and 65-74). Similar effects were found for total MFIS fatigue with individuals aged 55-64 reporting greater overall fatigue than 35-44 year olds. Finally, 18-24 year olds reported significantly higher levels of cognitive fatigue compared to 35-44 and 65-74 aged cohorts. No other effects were observed for age. Individuals with higher education consistently reported less fatigue. Subsequent analyses also revealed an interaction effect for age x gender. When examining the age x gender interaction, women age 18-24 reported significantly greater levels of physical, cognitive, psychosocial, and total fatigue than their male counterparts. In contrast, men aged 65-74 reported greater physical, cognitive, and total fatigue than women their age. Comparisons of the existing cutoff of the MFIS to the new age, gender, and education specific cutoffs found either comparable or slightly higher rates of fatigue with the latter. CONCLUSION: Based on these findings, updated normative data and age, gender, and education specific cutoffs are provided. Utilization of these updated norms will result in a more accurate assessment of fatigue and will be valuable for those conducting research and/or clinical practice with individual with MS.

A new look at an old test: Normative data of the symbol digit modalities test -Oral version.

BACKGROUND: The Symbol Digit Modalities Tests (SDMT) is the most sensitive measure to multiple sclerosis (MS)-related cognitive dysfunction. However, existing normative data has been under scrutiny. Specifically, they are outdated, do not take into account gender, and are poorly stratified by education. More importantly, there exists no oral only version norms, which is typical administration among individuals with MS. OBJECTIVE: The present investigation aimed to develop updated normative data of the oral version SDMT in which age, gender, and education were taken into consideration. METHODS: A total of 675 healthy individuals, stratified by age, gender, and education completed the oral version SDMT. RESULTS: Significant effects were found for age, gender, and education, consistent with previous contentions. Specifically, performance on the SDMT tends to decline with age, with the most noticeable decline beginning in the third decade of life and continuing into the sixth decade. Women, in general perform better than men, with an average of 5.1 more points. Finally, education effects were apparent among those aged 25-54. CONCLUSION: Based on these findings, updated normative data are provided. Utilization of these updated norms will result in a much needed and more accurate assessment of processing speed for individuals with MS.

Lysolecithin, but not lecithin, improves nutrient digestibility and growth rates in young broilers.

1. The potential of lecithin and lysolecithin to improve lipid digestion and growth performance was investigated in three experiments: 1. an in vitro model that mimics the intestinal conditions of the chick, 2. a digestibility trial with chicks (5-7 days of age), and 3. a performance trial until 21 days of age. 2. In experiment 1, palm oil (PO), palm oil with lecithin (PO+L), and palm oil with lysolecithin (PO+LY) were subjected to in vitro hydrolysis and applied to Caco-2 monolayers to assess lipid absorption. 3. The in vitro hydrolysis rate of triglycerides was higher in PO+LY (k = 11.76 × 103/min) than in either PO (k = 9.73 × 103/min) or PO+L (k = 8.41 × 103/min), and the absorption of monoglycerides and free fatty acids was highest (P < 0.01) for PO+LY. In experiment 2, 90 broilers were assigned to three dietary treatments: a basal diet with 4% palm oil, and the basal diet supplemented with either 250 ppm lecithin or lysolecithin. 4. ATTD of crude fat was higher in broilers supplemented with lysolecithin, but was lower in broilers supplemented with lecithin. DM digestibility and AMEn in birds supplemented with lysolecithin were significantly higher (3.03% and 0.47 MJ/kg, respectively). 5. In experiment 3, 480 broilers were randomly allocated to four dietary treatments: basal diet with soybean oil (2%), basal diet with lecithin (2%), soybean oil diet with 250 ppm lysolecithin, or lecithin oil diet with 250 ppm lysolecithin. 6. Lecithin diets significantly reduced weight at day 10 and 21 compared with soybean oil. However, the addition of lysolecithin to lecithin-containing diets significantly improved bird performance. 7. The results of these studies showed that, in contrast to lecithin, lysolecithin was able to significantly improve the digestibility and energy values of feed in young broilers.

The addition of lysolecithin to broiler diets improves growth performance across fat levels and sources: a meta-analysis of 33 trials.

1. This study aimed to quantify the effect of fat type (including unsaturated to saturated ratio (U:S)) and increasing doses of lysolecithin-based products on nutrient availability and growth performance in broiler chickens.2. A total of 33 separate experimental reports were collated according to predetermined selection criteria to provide 16 performance trials with 'on top' application, and 17 performance trials using reformulated diets, where the contribution of the lysolecithin was taken into account. Data on average daily gain (ADG) and body weight corrected FCR (FCRc) were analysed using the REML method with trial as a random effect.3. Across the constituent trials, average added dietary fat and oil inclusion was 4.42% (min 1.15%, max 7.00%), with varied U:S ratio (min 0.94, avg 2.50, max 7.65), reflecting diverse fat sources. Overall, neither bird growth performance nor response to lysolecithin supplementation were significantly affected by the U:S ratio of the diets.4. In performance trials where lysolecithin was added 'on top' of existing formulations, FCRc was significantly reduced by lysolecithin at 250 g/t inclusion compared to the control, with 125 g/t returning an intermediate value. In reformulated trials, FCRc was not significantly affected, suggesting lysolecithin supplementation at 125 and 250 g/t could recover average dietary energy reductions of 57.88 and 73.11 kcal/kg feed, respectively.5. In conclusion, this study showed that the addition of lysolecithin at levels of 125 g/t and above to broiler diets consistently improved feed efficiency across a range of basal dietary ingredients and fat sources.

Impact of genotypic susceptibility score on cART outcomes during primary HIV infection.

To assess the impact of genotypic susceptibility score (GSS) on combined antiretroviral therapy (cART) outcomes during primary HIV infection (PHI) we retrospectively enrolled patients with PHI diagnosed between 2008 and 2015 at 9/24 Italian Network ACuTe HIV InfectiON centers. One hundred-seventy-six patients were enrolled. Of these, 55 (32.9%) patients started with more than three drugs and 11 (7.2%) started with a GSS < 3. Regimen's GSS (per 1 point increase) (adjusted odds ratio [aOR], 4.82; 95% confidence interval [CI], 1.62-14.28; P = .005) and baseline HIV-RNA (per 1 log10 increase) (aOR, 2.02; 95% CI, 1.09-3.73; P = .025) resulted associated with early cART initiation. In conclusion, regimen's GSS resulted to be associated to the time to cART initiation during PHI.

Obstructive sleep apnea syndrome in the pediatric age: the role of the pneumologist.

OBJECTIVE: This review paper aims to summarize the current state of knowledge on the role of the pneumologist in the diagnosis and respiratory treatment of children affected by obstructive Sleep Disordered Breathing (SDB). MATERIALS AND METHODS: A literature review has been performed on the following topics: obstructive SDB and its clinical entities, indications for respiratory treatment of pediatric SDB, and Continuous Positive Airway Pressure (CPAP) and Noninvasive Positive Pressure Ventilation (NIPPV) treatment approach to obstructive SDB. RESULTS: OSDB is related to obesity, craniofacial pathologies, neuromuscular disorders and, most commonly, oadenotonsillar hypertrophy. Adenotonsillectomy is the first-choice treatment in children with obstructive apnea secondary to adenotonsillar hypertrophy. CPAP and NIPPV are recommended in cases where Obstructive Sleep Apnea (OSA) persists after surgery or when surgery is contraindicated. Treatment interventions are usually implemented gradually by separately addressing each abnormality that would predispose to obstructive SDB, then reevaluating after each intervention to detect any residual disease and to assess the need for additional treatment. CONCLUSIONS: Many pediatric patients continue to experience problems and symptoms such as hypersomnia and apnea after adenotonsillectomy and need CPAP/NIPPV treatment. Current knowledge is still incomplete, especially with regard to the mechanisms of pathogenesis of pediatric OSA, the factors affecting pediatric OSA, and the phenotypic variability of the disease. A better understanding of these aspects would contribute to the development of new therapies.

Obstructive sleep apnea syndrome in the pediatric age: the role of the otorhinolaryngologist.

OBJECTIVE: Obstructive sleep apnea (OSA) is the primary indication for tonsillectomy, one of the most common pediatric surgical procedures, commonly performed in association with adenoidectomy. The objective of this review article is to evaluate the role of the otorhinolaryngologist in pediatric OSA. MATERIALS AND METHODS: A literature review has been performed on the following topics: peculiarities of sleep-disordered breathing in pediatric age; discrimination of sleep disorders; adenotonsillar hypertrophy; surgical techniques; adjuvant surgical procedures. RESULTS: The role of the otorhinolaryngologist in pediatric OSA is important for the evaluation of the upper airways and of essential biometric and polysomnographic data and for indication and execution of appropriate surgical treatment. In the majority of healthy children, adenotonsillectomy for OSA results in a dramatic improvement in respiratory parameters as measured by polysomnography. When post-surgical residual OSA occurs, it is essential to monitor patients by means of drug-induced sleep endoscopy (DISE). CONCLUSIONS: Otolaryngologic assessment is of paramount importance to correctly classify a child with OSA. Correct inspection of the upper airway and quantification of the quality of sleep through polysomnography lead to the right therapeutic choice. Knowledge of different surgical techniques helps to deal with residual OSA after studying the obstruction sites by drug-induced sedation endoscopy.

Therapy Adherence and Emotional Awareness and Regulation in Persons With Human Immunodeficiency Virus.

Adherence to antiretroviral therapy (ART) is a key issue for people with human immunodeficiency virus. Optimal adherence leads to benefits in terms of survival and quality of life, which do not occur with incomplete adherence. One factor that may influence adherence to ART is emotional unawareness deficits. To explore this possibility, we assessed emotional deficits and measured adherence in 100 adults using both self-report and viral load testing. Results showed that people classified as adherent in both measurements were more likely to have a greater awareness of their own emotions. Participants classified as nonadherent were more likely to have a reduced ability to recognize the emotions of others. Difficulty in recognizing one's own emotions, otherwise known as alexithymia, and impairment of the ability to recognize other's emotions may contribute to nonadherence to ART. Consequently, after repeated studies to confirm the findings, it can be considered a target for psychological therapies aimed at increasing adherence.

Prevalence and characteristics of positional plagiocephaly in healthy full-term infants at 8-12 weeks of life.

Positional plagiocephaly (PP) denotes flattening of the skull that occurs frequently in healthy infants. Aim of this study was to estimate the prevalence of positional plagiocephaly and to identify the risk factors in a cohort of healthy infants in order to help prevention of PP. In a prospective design, all healthy full-term infants, ranging from 8 to 12 weeks of age, who presented at the public immunization clinic in Ferrara, were eligible for the study. After obtaining informed consent, we interviewed the parents and examined the infants using the Argenta's assessment tool. Of 283 infants examined, 107 (37.8%) were found to have PP at 8-12 weeks of age. In 64.5%, PP was on the right side, 50.5% were male and 15% presented also with brachycephaly. Risk factors significantly associated were lower head circumference, advanced maternal age, Italian compared to African, and supine sleep position, in particular for infants born at 37 weeks, preference for one side of the head. In logistic regression, risk factors significantly associated were lower birth weight, advanced maternal age, and supine sleep position. CONCLUSIONS: Positional plagiocephaly is a common issue faced by pediatricians; our results reinforce the need of improving prevention both of sudden infant death and positional plagiocephaly, through uniform messages provided prenatally and postnatally by different health professionals. "What is Known:" •The incidence of positional plagiocephaly varies due to population studied and measuring methods. •Different factors are considered in the literature as being associated to positional plagiocephaly (infant factors, obstetric factors, infant care practices, sociodemographic factors). "What is New:" •This is one of the few European studies quantifying positional plagiocephaly prevalence in a population of unselected healthy infants. •In this study, positional plagiocephaly is confirmed as a common issue, related to some factor (as supine sleep position and positional head prevalence) that should be addressed in pre and postnatal counseling. •The prone sleepers rate in our population highlight the need to improve parental awareness regarding SIDS prevention, in particular in borderline gestational age.

Dolutegravir Plus Rilpivirine as a Switch Option in cART-Experienced Patients: 96-Week Data.

BACKGROUND: Data from clinical studies confirm the efficacy of switching to dolutegravir (DTG) plus rilpivirine (RPV) in selected patients. OBJECTIVE: The primary objective is to report the 96-week virological suppression in our cohort, assessing the durability of this strategy in complicated situations. The secondary objective is to describe the safety and metabolic profile. METHODS: All patients who had switched to DTG plus RPV between October 1, 2014, and September 30, 2015, were analyzed using a retrospective-prospective design, approved by ethics committees. Routine metabolic, immunological, and virological data were regularly sent to the coordinating center. Viral control was classified as HIV-1 RNA ≥50 copies/mL, 1 to 49 copies/mL, or undetectable (no virus detected [NVD]). RESULTS: We followed 145 patients for a median of 101 weeks. The median age was 52 years; 31.7% were women, and 9.6% non-Caucasian; 50.3% had failed at least 1 antiretroviral regimen; and 15% had ≥50 copies/mL at baseline. The reasons for switching were as follows: simplification (51.7%), toxicity (36.5%), drug-drug interactions (6.9%), persistent low-level viremia (3.0%), nonadherence (2.1%), and viral failure (1.4%). By week 96, seven patients dropped out. At week 96, none had ≥50 HIV-1 RNA copies/mL, 138 (95.2%) had <50 copies/mL, and 123 (84.8%) had NVD. The low- to high-density lipoprotein cholesterol (LDL-C/HDL-C) ratio decreased significantly ( P = 0.04). Of the 287 baseline altered laboratory parameters, 32.7% normalized by week 96. Serum glucose and total- and LDL-cholesterol normalization were statistically significant. CONCLUSIONS: Switching to DTG plus RPV improved viral suppression and LDL-C/HDL-C ratio.

Effects of lysolecithin supplementation in low-energy diets on growth performance, nutrient digestibility, viscosity and intestinal morphology of broilers.

1. The study aimed to investigate the effect of lysolecithin supplementation in low-energy diets on growth, nutrient digestibility and intestinal mucosa characteristics of broilers. 2. A total of 800 one-d-old Ross 308 broiler chickens were assigned to 4 dietary treatments consisting of 10 replicates of 20 broilers each. Broilers were fed with 4 different diets: (i) HE: positive control group broilers received a diet with unaltered energy; (ii) LE: negative control group broilers received a diet with lower energy of about 0.27 MJ/kg; (iii) LElys500: broilers received a diet similar to LE supplemented with 500 g/tn lysolecithin product (Lysoforte Booster DryTM); and (iv) LElys300: broilers received a diet similar to LE supplemented with 300 g/tn lysolecithin product. The experimental period was 42 d. 3. Body weight gain in treatments HE was higher than LE during the overall experimental period, while LElys500 and LElys300 had intermediate values. Feed conversion ratio was lower in HE and LElys500 than LE group, while the LElys300 had intermediate values. Fat digestibility was improved in both LElys 500 and LElys300 compared to the HE group. Apparent metabolisable energy (AMEn) was higher in HE, LElys500 and LElys300 than LE. Ileum viscosity at 42 d was also affected, being higher in LE group compared to HE. At 28 d mucosal thickness was lower both in LElys500 and LElys300 compared to HE and LE, while no difference occurred between treatment proliferation patterns of duodenal epithelial cells. 4. These findings indicated that lysolecithin supplementation at 500 g/tn of feed in low-energy diets maintained broiler performance. Supplementation of reformulated low-energy diets induced an increase in digesta viscosity. Lysolecithin supplementation resulted in variable alterations in the duodenum mucosal morphology.

Durability of dolutegravir plus boosted darunavir as salvage or simplification of salvage regimens in HIV-1 infected, highly treatment-experienced subjects.

BACKGROUND: Dolutegravir (DTG) plus boosted darunavir (bDRV) is a compact, adherence-friendly salvage regimen with the highest genetic barrier to HIV-1 resistance. OBJECTIVE: Aim of the present study is to assess the long term (96-week) safety and efficacy of DTG + bDRV in a of multidrug-experienced HIV-1 infected patients, simplifying or building rescue regimens. METHODS: All HIV-1-infected subjects from eleven Italian centers switched to DTG + bDRV between March 2014 and September 2015 were included and followed for minimum 96 weeks. RESULTS: The cohort comprises 130 subjects, switched from 42 different, complex or at least twice-daily regimens, mainly for simplification (44.6%), viral failure (30.0%) or toxicity (16.6%). At baseline 118 had documented resistance to 1-5 antiretroviral classes and 12 lacked genotypic results either for historical reasons or for problems with primer annealing; 52 (40%) had uncontrolled viral replication, three above 500.000 copies/mL. At week 96 two showed ≥50 HIV-1 RNA copies/mL, 23 had 1-49 copies/mL and 101 had no virus detected. The proportion of subjects presenting abnormal values at baseline significantly decreased for serum glucose, creatinine, AST, total cholesterol and triglycerides. CONCLUSIONS: These long-term data confirm the reliability of the two-drug regimen consisting of bDRV plus DTG in salvage settings in HIV-1 infection.

Prospective multicentre study on barbed reposition pharyngoplasty standing alone or as a part of multilevel surgery for sleep apnoea.

OBJECTIVES: The aim of this study was to demonstrate in a prospective multicentre study that Barbed Reposition Pharyngoplasty (BRP) procedure is safe and effective in management of obstructive sleep apnoea/hypopnea syndrome (OSAHS) patients. DESIGN: Prospective study. SETTING: Multicentre study. PARTICIPANTS: Patients suffering from obstructive sleep apnoea. MAIN OUTCOMES MEASURES: Values of postoperative apnoea-hypopnea index (AHI), oxygen desaturation index (ODI), epworth sleepiness scale (ESS). RESULTS: 111 Barbed Reposition Pharyngoplasty procedures standing alone or as a part of multilevel surgery for OSAHS, performed between January and September 2016, were analysed in 15 different centres. The average hospitalisation period was 2.5 ± 0.5 days. The mean patient age was 46.3 ± 10.5 years. The average body mass index at the time of the procedure was 27.9 ± 3.2, and the majority of the patients were men (83%). The mean preoperative and postoperative apnoea/hypopnea index was 33.4 ± 19.5 and 13.5 ± 10.3, respectively (P < .001). The mean preoperative and postoperative ESS score was 10.2 ± 4.5 and 6.1 ± 3.6, respectively (P < .001). The mean preoperative and postoperative ODI were 29.6 ± 20.7 and 12.7 ± 10.8, respectively (P < .001). CONCLUSIONS: Patients undergoing BRP standing alone or as part of a multilevel approach for the treatment of OSAHS have a reasonable expectation for success with minimal morbidity.

Prevention of neural tube defects and maternal gestational diabetes through the inositol supplementation: preliminary results.

OBJECTIVE: Our study aims to demonstrate that the use in the preconceptional period until the 24th week of pregnancy of inositol and folic acid, first of all, preserves the product of conception from neural tube defects (NTDs) and then, thanks to inositol supplementation, it possibly counteracts and prevents the onset of maternal gestational diabetes (GDM). PATIENTS AND METHODS: We have collected data derived from pregnant women arrived at our laboratory, from January 2014 to January 2016, with no family history of type 2 diabetes and hypertension. The first group (n = 68 women) was treated from the preconceptional period until the 24th week of pregnancy with 1.75 g/day myo-inositol, 250 mg/day D-chiro-inositol, 12.5 mg/day Zinc pidolate, 100 mg/day methylsulfonylmethane, 120 mg/day Vitamin C and 400 mcg/day (6S)-5-methyltetrahydrofolic acid. The control group (n = 72) was only treated with 400 mcg/day folic acid. The main outcome measure was the prevalence of maternal GDM. Secondary outcome measures were the prevalence of NTDs and fetal macrosomia. RESULTS: A significant difference was found regarding body mass index (BMI), fasting oral glucose tolerance test (OGTT), after 1-h-glucose OGTT, 2-h-glucose OGTT, glycated hemoglobin (HbA1c) and serum folate, between the two groups. Five infants, in the control group, weighted greater than 4 kg. Moreover, we found a positive correlation between HbA1c and OGTT at the 24th week of pregnancy. CONCLUSIONS: This study shows the efficacy of preconceptional supplementation of inositol to reduce the risk of the onset of GDM and to confirm the importance of folic acid supplementation to avoid NTDs development. Moreover, the positive correlation between HbA1c and OGTT may be useful to consider the use of HbA1c as a single tool for GDM prevention and diagnosis in selected woman in pregnancy.

Role of Normalized T-Cell Subsets in Predicting Comorbidities in a Large Cohort of Geriatric HIV-Infected Patients.

BACKGROUND: Adults aging with HIV are at greater risk for several comorbidities. The CD4 cell count and CD4/CD8 ratio often fail to normalize in elderly patients despite prolonged antiretroviral therapy; this has been associated with concomitant diseases and poor prognosis. METHODS: A cross-sectional analysis in antiretroviral-treated HIV-positive patients aged 65 years and older. The aim of the study was to describe the predictors of normalized T-cell subsets ("nT", CD4/CD8 ratio ≥1 and CD4 ≥500 cells/µL) in a cohort of geriatric HIV-positive patients and its association with HIV-associated non-AIDS conditions (HANA). RESULTS: One thousand ninety-two patients were included: nT was observed in 340 patients (31.1%). Multivariate binary logistic analysis showed that plasma HIV RNA <50 copies/mL (P = 0.004), female sex (P = 0.002), and nadir CD4 cell count (P < 0.001) were independent predictors of nT. Age and sex-adjusted prevalence of hypertension (P = 0.037), lipid abnormalities (P = 0.040), and multimorbidity (P = 0.034) were higher in subjects with nT, whereas chronic obstructive pulmonary disease (COPD) and cancer were lower (respectively, P = 0.028 and P = 0.005). Multivariate analysis showed that HIV duration was an independent predictor of several comorbidities, whereas nT was protective for cancer and COPD. HIV duration and nT were simultaneously predictors of multimorbidity. CONCLUSIONS: Normalized T-cell subsets were observed in approximately one-third of geriatric HIV-positive subjects, and they were predicted by female sex and immunovirological features. HIV-associated non-AIDS conditions were more prevalent in patients with longer HIV duration, whereas nT represented a protective factor for cancer and COPD.
