Psychotic disorders in young adults with perinatally acquired HIV: a UK case series.

BACKGROUND: Increasing numbers of children with perinatally acquired HIV (PaHIV) are transitioning into adult care. People living with behaviourally acquired HIV are known to be at more risk of psychosis than uninfected peers. Young adults living with PaHIV face numerous risk factors; biological: lifelong exposure to a neurotrophic virus, antiretroviral medication and immune dysfunction during brain development, and environmental; social deprivation, ethnicity-related discrimination, and migration-related issues. To date, there is little published data on the prevalence of psychotic illness in young people growing up with PaHIV. METHODS: We conducted a retrospective case note review of all individuals with PaHIV aged over 18 years registered for follow up at a dedicated clinic in the UK (n = 184). RESULTS: In total, 12/184 (6.5%), median age 23 years (interquartile range 21-26), had experienced at least one psychotic episode. The presentation and course of the psychotic episodes experienced by our cohort varied from short-lived symptoms to long term illness and nine (75%) appear to have developed a severe and enduring mental illness requiring long term care. CONCLUSION: The prevalence of psychosis in our cohort was clearly above the lifetime prevalence of psychosis in UK individuals aged 16-34 years, which has been reported to be 0.5-1.0%. This highlights the importance of clinical vigilance regarding the mental health of young people growing up with PaHIV and the need to integrate direct access to mental health services within the HIV centres providing medical care.

Cucurbita ficifolia (Cucurbitaceae) modulates inflammatory cytokines and IFN-γ in obese mice.

This study investigated the effect of aqueous extract of Cucurbita ficifolia Bouché on systemic chronic inflammation in an obesity model induced by monosodium glutamate (MSG) via modulating the expression of adipokines (TNF-α, IL-6, resistin, and adiponectin) and immune-regulatory cytokines (IFN-γ and IL-10). Cucurbita ficifolia extract was administered daily by gavage to lean and MSG-obese mice for 30 days. At the end of treatment, cytokine mRNA expression in adipose tissue was determined by real-time polymerase chain reaction (PCR), and the protein levels of these cytokines were also quantified by enzyme-linked immunosorbent assay (ELISA). Cucurbita ficifolia extract decreased body mass and inflammation in MSG-obese mice by reducing the expression of TNF-α and IL-6; these decreases were parallel to significant reductions in protein levels. The extract also increased protein levels of IL-10 in lean mice and IFN-γ in both lean and MSG-obese mice. In conclusion, C. ficifolia extract modulates systemic chronic inflammation in MSG-obese mice and could have a beneficial effect on the adaptive immune system in obesity.

Cytokine profile determined by data-mining analysis set into clusters of non-small-cell lung cancer patients according to prognosis.

BACKGROUND: Immunoregulatory cytokines may play a fundamental role in tumor growth and metastases. Their effects are mediated through complex regulatory networks. Human cytokine profiles could define patient subgroups and represent new potential biomarkers. The aim of this study was to associate a cytokine profile obtained through data mining with the clinical characteristics of patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: We conducted a prospective study of the plasma levels of 14 immunoregulatory cytokines by ELISA and a cytometric bead array assay in 110 NSCLC patients before chemotherapy and 25 control subjects. Cytokine levels and data-mining profiles were associated with clinical, quality of life and pathological outcomes. RESULTS: NSCLC patients had higher levels of interleukin (IL)-6, IL-8, IL-12p70, IL-17a and interferon (IFN)-γ, and lower levels of IL-33 and IL-29 compared with controls. The pro-inflammatory cytokines IL-1b, IL-6 and IL-8 were associated with lower hemoglobin levels, worse functional performance status (Eastern Cooperative Oncology Group, ECOG), fatigue and hyporexia. The anti-inflammatory cytokines IL-4, IL-10 and IL-33 were associated with anorexia and lower body mass index. We identified three clusters of patients according to data-mining analysis with different overall survival (OS; 25.4, 16.8 and 5.09 months, respectively, P = 0.0012). Multivariate analysis showed that ECOG performance status and data-mining clusters were significantly associated with OS (RR 3.59, [95% CI 1.9-6.7], P < 0.001 and 2.2, [1.2-3.8], P = 0.005). CONCLUSION: Our results provide evidence that complex cytokine networks may be used to identify patient subgroups with different prognoses in advanced NSCLC. These cytokines may represent potential biomarkers, particularly in the immunotherapy era in cancer research.

In vivo environment necessary to support transplanted donor mouse T regulatory cells.

CD4(+) Foxp3(+) T regulatory cells (Tregs ) are essential for maintaining immunological tolerance, which could be harnessed for novel cell-based therapies to prevent allograft rejection and control autoimmunity. However, the use of Tregs for therapy is hindered by the inability to generate sufficient cell numbers to inhibit desired immune response(s) and achieve stable engraftment of the donor-Treg cell inoculums. The present study was undertaken to investigate the in vivo requirements to promote engraftment of adoptively transferred Tregs and induce tolerance. We established that not only is peripheral space required, but competition from endogenous Tregs must be minimized for successful donor-Treg engraftment with IL-2 critical for driving their proliferation and survival. Moreover, these studies revealed a critical level of donor-Treg engraftment was required for tolerance induction to skin transplants. These mouse studies lay the foundation for development of novel Treg approaches for tolerance induction in the clinic involving not only organ or cellular transplantation, but also to re-establish self-tolerance in autoimmune settings.

Production of poly-3-hydroxybutyrate (PHB) nanoparticles using grape residues as the sole carbon source.

The production of poly-3-hydroxybutyrate (PHB) on an industrial scale remains a major challenge due to its higher production cost compared to petroleum-based plastics. As a result, it is necessary to develop efficient fermentative processes using low-cost substrates and identify high-value-added applications where biodegradability and biocompatibility properties are of fundamental importance. In this study, grape residues, mainly grape skins, were used as the sole carbon source in Azotobacter vinelandii OP cultures for PHB production and subsequent nanoparticle synthesis based on the extracted polymer. The grape residue pretreatment showed a high rate of conversion into reducing sugars (fructose and glucose), achieving up to 43.3 % w w-1 without the use of acid or external heat. The cultures were grown in shake flasks, obtaining a biomass concentration of 2.9 g L-1 and a PHB accumulation of up to 37.7 % w w-1. PHB was characterized using techniques such as Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The formation of emulsified PHB nanoparticles showed high stability, with a particle size between 210 and 240 nm and a zeta potential between -12 and - 15 mV over 72 h. Owing to these properties, the produced PHB nanoparticles hold significant potential for applications in drug delivery.

Sexual Assault: Approach to Reality in the Area of Santiago de Compostela (Galicia, Spain) through a 12-Year Retrospective Study.

Sexual assault constitutes a severely traumatic experience that impacts the lives of far too many victims each year. The underlying behaviors of the offenders are often associated with psychological, physical and social distress, and the use of psychotropic substances was found in a good number of cases. A descriptive and retrospective review of sexual assault cases has been undertaken to identify trends in the toxicology findings in Drug-Facilitated Sexual Assault in Santiago de Compostela over the past 12 years. During this period, a total of 69 cases were referred to the Forensic Toxicology Service as sexual assault cases. The sex and age distribution of the cases showed that females between the ages of 14 and 65 years constituted the group most frequently submitted to sexual assault, with a peak of 55.1% in the 18- to 30-year age group. Alcohol consumption was positive in 77.1% of positive cases determined, followed by drugs (34.4%) and illicit drugs (26.2%). Our results showed a high percentage of alcohol consumption in sexual assault cases.

Time of the day of exercise impact on cardiovascular disease risk factors in adults: a systematic review and meta-analysis.

OBJECTIVES: To compare the effect of a single bout of morning vs. evening exercise on cardiovascular risk factors in adults. DESIGN: Systematic review and meta-analysis. METHODS: A systematic search of studies was conducted using PubMed and Web of Science from inception to June 2022. Selected studies accomplished the following criteria: crossover design, acute effect of exercise, blood pressure, blood glucose, and/or blood lipids as the study's endpoint, a washout period of at least 24 h, and adults. Meta-analysis was performed by analyzing: 1) separated effect of morning and evening exercise (pre vs. post); and 2) comparison between morning and evening exercise. RESULTS: A total of 11 studies were included for systolic and diastolic blood pressure and 10 studies for blood glucose. Meta-analysis revealed no significant difference between morning vs. evening exercise for systolic blood pressure (g ∆ = 0.02), diastolic blood pressure (g ∆ = 0.01), or blood glucose (g ∆ = 0.15). Analysis of moderator variables (age, BMI, sex, health status, intensity and duration of exercise, and hour within the morning or evening) showed no significant morning vs. evening effect. CONCLUSIONS: Overall, we found no influence of the time of the day on the acute effect of exercise on blood pressure neither on blood glucose.

Disappearance of codeine, morphine and 6-MAM in hair after cessation of abuse.

Research on the determination of drugs of abuse in hair has established that drugs can be detected in hair even long after cessation of use. The purpose of this study was to analyze hair samples from chronic opioid users who were beginning a controlled drug cessation program. The study population (n = 15) is involved in a drug rehabilitation program in Santiago de Compostela, Spain. Over a 6-month period, subjects provided hair samples at 2-month intervals, with the first sample collected on the day they began the program. Codeine, morphine, and 6-MAM were analyzed by GC/MS (LOQ = 0.2 ng/mg). Hair tresses were divided into 1 cm segments and analyzed for all analytes 0-1 cm corresponding to the proximal portion to the scalp Following cessation of opioid use, traces of codeine, morphine, and 6-MAM still remained in the newly growing hair segments for a specified period. After 2 months, still 27 % of the users tested positive, and at 4 months, 20 % were positive but only for 6-MAM. However, after 6 months of abstinence, the results were negative for all analytes.

Detection of coca alkaloids in oral fluid from coca leaf (tea) consumers: using solid phase extraction to improve validation parameters and widen the detection window.

Hygrine and cuscohygrine, two coca leaf alkaloids, have been previously proposed as markers to differentiate legal and illegal cocaine consumption. This is a very common problem in some countries of South America, where the consumption of coca leaves has a long tradition. Analytical methods focusing on the assessment of coca leaf alkaloids, such as cuscohygrine, hygrine, tropacocaine and t-cinnamoylcocaine, in oral fluid are virtually non-existent in forensic toxicology laboratories worldwide due to their lack of application. However, the problem of differentiating legal and illegal cocaine use in criminal justice, DUID (drug-impaired driving) and WDT (workplace drug testing) programs is growing. Therefore, researchers are obliged to develop methods to measure coca leaf alkaloids (cuscohygrine, hygrine and t-cinnamoylcocaine) in biological matrices for further validation for routine analyses in forensic toxicology laboratories. This work aims to optimize a previously published separation method by protein precipitation in oral fluid by using solid-phase extraction (SPE) coupled with liquid chromatography-tandem mass spectrometry (LC-MS/MS) operating in multiple reaction monitoring (MRM) mode. The use of SPE allowed the matrix effect and the background to be reduced in the chromatograms due to the obtained cleaner extracts. Consequently, improved detection and quantification limits were reached. Findings showed that the detection windows for coca leaf alkaloids were longer than three hours in real oral fluid samples from volunteers who drank a cup of coca tea. These detection windows are quite higher than those previously obtained when using the method based on separation by protein precipitation.

Nano and micro reoriented domains and their relation with the crystal structure in the New Fe1.5Zn1.5B7O13Cl boracite.

New iron-zinc chlorine single crystals of Fe1.5Zn1.5B7O13Cl boracite were grown by chemical transport reactions in closed quartz ampoules, at a temperature of 1173 K. The crystal structure was characterized by X-ray powder diffraction (XRD) using the Rietveld refinement method and belongs to the trigonal/rombohedral system with space group R3c (No. 161). The cell parameters were a = 8.5726(1) angstroms, c = 21.0116(4) angstroms, V = 1337.26(3) angstroms3 and Z = 6. The refinement successfully proceeded and ended with sound merit figure values chi2 = 2.25, R(B) = 6.12%. Chemical analysis was performed with X-ray energy dispersive spectroscopy (EDS) and X-ray fluorescence (XRF). Ferroelectric nano and micro reoriented domains were found in this material using polarizing optical microscopy (PLM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The examination by TEM showed that in the trigonal/rombohedral system of Fe1.5Zn1.5B7O13Cl nanodomain structures exist. Thin (50-100 nm) mostly planar domains parallel to (100) were frequently observed in Fe1.5Zn1.5B7O13Cl boracite.

Determination of Seven Antidepressants in Pericardial Fluid by Means of Dispersive Liquid-Liquid Microextraction (DLLME) and Gas Chromatography-Mass Spectrometry (GC/MS).

Although blood is often used to detect and quantify the presence of drugs, there are some instances where samples obtained from other biological matrices, like pericardial fluid (PF), are necessary since adequate blood samples may not be available. PF is an epicardial transudate, which contains plasma components that include toxicological substances making this sample useful when blood samples are not available. This fluid is a well preserved postmortem sample and can easily be collected in larger amounts without significant contamination, compared with other body fluids. Although studies involving PF began around the 1980's, the adequacy of such fluid as a biological matrix has been poorly investigated. Antidepressants are frequently detected in postmortem samples from forensic cases. Nowadays, they constitute some of the most commonly prescribed drugs worldwide. A total of seven antidepressants (venlafaxine, mirtazapine, olanzapine, paroxetine, sertraline, fluoxetine and citalopram) were evaluated in this study. A new extraction method involving dispersive liquid-liquid microextraction (DLLME) is presented in which chloroform and acetonitrile are determined to be the best extraction and dispersing solvents. The experimental design was achieved using StatGraphics 18. The Response Surface Methodology enabled us to know the optimal volume for the two solvents used in the DLLME. The detection technique used was gas chromatography-mass spectrometry (GC-MS) with electron impact ionization as ionization source. A temperature gradient has been used and the total chromatographic separation time was 19.43 min. Validation results met the international validation guidances (FDA). Under the optimal condition, the method offered good validation parameters showing a new efficient, simple, rapid, and sensitive method. The analytical method was applied to thirty-one pericardial fluid samples. Twenty-one samples were positive with concentrations between 0.19 and 8.48 µg/mL. Venlafaxine and olanzapine were the antidepressants most frequently found.

Chemical characterization (LC-MS-ESI), cytotoxic activity and intracellular localization of PAMAM G4 in leukemia cells.

Generation 4 of polyamidoamine dendrimer (G4-PAMAM) has several biological effects due to its tridimensional globular structure, repetitive branched amides, tertiary amines, and amino-terminal subunit groups liked to a common core. G4-PAMAM is cytotoxic due to its positive charges. However, its cytotoxicity could increase in cancer cells due to the excessive intracellular negative charges in these cells. Furthermore, this work reports G4-PAMAM chemical structural characterization using UHPLC-QTOF-MS/MS (LC-MS) by electrospray ionization to measure its population according to its positive charges. Additionally, the antiproliferative effects and intracellular localization were explored in the HMC-1 and K-562 cell lines by confocal microscopy. The LC-MS results show that G4-PAMAM generated multivalent mass spectrum values, and its protonated terminal amino groups produced numerous positive charges, which allowed us to determine its exact mass despite having a high molecular weight. Additionally, G4-PAMAM showed antiproliferative activity in the HMC-1 tumor cell line after 24 h (IC50 = 16.97 µM), 48 h (IC50 = 7.02 µM) and 72 h (IC50 = 5.98 µM) and in the K-562 cell line after 24 h (IC50 = 15.14 µM), 48 h (IC50 = 14.18 µM) and 72 h (IC50 = 9.91 µM). Finally, our results showed that the G4-PAMAM dendrimers were located in the cytoplasm and nucleus in both tumor cell lines studied.

Magnetic double-J stent: Evaluation of tolerance and impact on quality of life compared to traditional double-J stent.

INTRODUCTION: The placement of a ureteral stent is one of the most widely performed procedures in urology. It can have a negative impact on the patients' quality of life, requiring a cystoscopy for its removal. The objective of this study is to evaluate the symptoms and impact on quality of life derived from the use of a magnetic double-J stent (Black Star®) and compare them to those presented in patients with a traditional double-J stent (OptiMed®). MATERIAL AND METHODS: We conducted a comparative, prospective, randomized study in 46 patients who underwent ureterorenoscopy with double-J stent placement between August 2019 and June 2020. Of all patients included, 23 had a traditional double-J stent placed (group A) and 23 had a magnetic double-J stent (group B) placed. We evaluated the results of the Ureteral Stent Symptom Questionnaire (USSQ) in both groups, assessed the technical difficulty related to stent removal and the pain during the procedure using the Visual Analogue Scale (VAS). We also reviewed the need for medical attention due to problems related to the stent or after its removal. RESULTS: There were no statistically significant differences between groups regarding the answers in the USSQ and the complications related to the use of the stent. Group B showed less pain (1.52 vs. 4, VAS, p = 0.001) and less difficulty during removal (1.61 vs. 3, p < 0.001) associated with a shorter procedure duration (11.65 min vs. 22.17 min p < 0.001). CONCLUSIONS: The tolerance shown by the use of magnetic double-J is comparable to the tolerance of traditional stent, since it does not cause an increase in urinary symptoms nor worsens the quality of life of patients during its use.

Quitting smoking does not increase the risk of major depressive episodes among users of Internet smoking cessation interventions.

BACKGROUND: Limited evidence has suggested that quitting smoking increases the incidence of major depressive episodes (MDEs), particularly for smokers with a history of depression. Further evidence for this increase would have important implications for guiding smoking cessation. METHOD: Spanish- and English-speaking smokers without a current MDE (n=3056) from an international, online smoking cessation trial were assessed for abstinence 1 month after their initial quit date and followed for a total of 12 months. Incidence of screened MDE was examined as a function of abstinence and depression history. RESULTS: Continued smoking, not abstinence, predicted MDE screened at 1 month [smoking 11.5% v. abstinence 7.8%, odds ratio (OR) 1.36, 95% confidence interval (CI) 1.04-1.78, p=0.02] but not afterwards (smoking 11.1% v. abstinence 9.8%, OR 1.05, 95% CI 0.77-1.45, p=0.74). Depression history predicted MDE screened at 1 month (history 17.1% v. no history 8.6%, OR 1.71, 95% CI 1.29-2.27, p<0.001) and afterwards (history 21.7% v. no history 8.3%, OR 3.87, 95% CI 2.25-6.65, p<0.001), although the interaction between history and abstinence did not. CONCLUSIONS: Quitting smoking was not associated with increased MDE, even for smokers with a history of depression, although a history of depression was. Instead, not quitting was associated with increased MDE shortly following a quit attempt. Results from this online, large, international sample of smokers converge with similar findings from smaller, clinic-based samples, suggesting that in general, quitting smoking does not increase the incidence of MDEs.

Laboratory analysis of a system for catchment, pre-treatment and treatment (SCPT) of runoff from impervious pavements.

This article reports the development and construction of a 1:1 scale laboratory prototype of a System for Catchment, Pre-treatment and Treatment (SCPT) of runoff polluted by contaminants washed from impervious pavements. The concept of the SCPT is an online system with an up-flow filter. The filter is composed of geotextile layers and limestone. The laboratory tests carried out were focused on determining the SCPT prototype behaviour under different working conditions. The variables studied were: inflow, pollutant loads and filtration system configuration. The results show that the system designed has a high capacity for treatment of solids and oil, with an average efficiency of 85% and 97% respectively. Moreover, the regression equations of the treatment efficiency were determined for each of the pollutants studied, for different inflow conditions and pollution loads.

Prevalence and implications of psychopathological non-cognitive symptoms in dementia.

OBJECTIVE: Clinical experience and recent population studies suggest that psychopathological, non-cognitive symptoms are both frequent and relevant in dementia. METHOD: A representative community sample (n = 4,803 individuals, 55 + years) was interviewed in a two-phase design. The Geriatric Mental Sate (GMS) was used for assessment and cases were diagnosed according to DSM-IV-TR criteria. RESULTS: The prevalence of non-cognitive symptoms (1 + symptoms) in cases of dementia (n = 223) was 90.1%, and negative-type symptoms were most frequently found. A GMS 'apathy-related symptom cluster' (anergia, restriction of activities and anhedonia) was significantly more frequent in the demented (55.6%) than in non-cases (0.7%; specificity = 99.2%). In both dementia of Alzheimer's type and vascular dementia, number of symptoms tended to be inversely related to severity of dementia, but psychopathological profiles differed. CONCLUSION: Non-cognitive, negative-type symptoms are very frequent in cases of dementia living in the community. They have powerful specificity in the distinction with non-cases, and might change current concepts of dementia.

Alginate molecular mass produced by Azotobacter vinelandii in response to changes of the O2 transfer rate in chemostat cultures.

Alginate production by Azotobacter vinelandii growing in chemostat cultures was evaluated under different O(2) transfer rates (OTR). As a result of modifying the culture's agitation rate from 300 to 500 rpm, the OTR increased from 9 to 15.1 mmol l(-1) h(-1) and a slight variation in the alginate production (1.7-2.2 g l(-1)) was observed. At a constant growth rate (0.1 h(-1)), the mean molecular mass of the alginate was strongly influenced by changes in the OTR, varying from 860 to 1,690 kDa. These results support a possible relationship between alginate polymerization-depolymerization process and the O(2) uptake rate.

[Hypertension high resolution consultation. A year of experience]. / Consulta de alta resolución (CAR) de HTA: experiencia de un año.

By High Resolution Consultation (HRC) we mean an ambulatory process of assistance fulfilled in a single day, by which treatment and diagnosis are established after all complementary tests have been carried out. Once diagnosed, the patient is discharged and resent to the doctor who had previously remitted him/ her. In the Cáceres sanitary area, with distances longer than 100- 120 km. and precarious local road communications, the introduction of hypertension (HTA) HRC has brought along important savings of sanitary and economical resources and it is perceived by the user as highly satisfactory. We have carried out an observational one- year study of our HCR HTA, in which 90 patients have been evaluated, out of which 74.4% came from primary assistance and 25.6% from specialized assistance. Once diagnosed, 61 patients were discharged and sent to receive primary assistance and 29 were kept in our outpatient nephrology consultation, justified by severe and/ or rebellious HTA in 11 cases and by renal failure in 16 cases; two of these patients are still being tested. Taking into account that in a traditional consultation a patient would need two or three visits and one or two days for complementary tests, our HTA HRC (by which patients are tested and diagnosed in a single day), brings along savings of one or two consultations and two to four relocations for new consultations and diagnostic explorations. In one year of HTA- HRC with 90 patients, we have saved from 212 to 302 consultations and from 302 to 604 relocations in comparison to the traditional organization and we have thus generated from 100 to 150 places for first appointments.
