Effectiveness and Safety of Direct-acting Antivirals for Treatment of Adolescents With HCV/HIV Coinfection: Real-world Data From Europe.

We evaluated the effectiveness and safety of direct-acting antivirals in adolescents with hepatitis C (HCV)/HIV coinfection using pooled individual patient-level data from 5 European cohorts. Of 122 participants in follow-up from November 2013 to August 2021, 19 were treated <18 years of age; of 15 with HCV RNA available at/after 12 weeks post-treatment, all had sustained virologic response with acceptable safety. This evidence addresses an important gap in knowledge of treatment outcomes in adolescents with HCV/HIV coinfection in real-life settings.

Development and Evaluation of an Axiom 60K SNP Array for Almond ().

A high-density single nucleotide polymorphism (SNP) array is essential to enable faster progress in plant breeding for new cultivar development. In this regard, we have developed an Axiom 60K almond SNP array by resequencing 81 almond accessions. For the validation of the array, a set of 210 accessions were genotyped and 82.

[Effectiveness of control over hemodynamic indexes and prognosis for patients with CHF and atrial fibrillation in real-life clinical practice].

Background: Earlier studies have demonstrated a high prevalence of atrial fibrillation (AF) in patients with CHF. It was noticed that tachycardia and hypotension provoked high risks for cardiovascular mortality. The presence of arterial hypertension (AH) in CHF patients also impairs life prognosis.

The Association Between HIV Disclosure Status and Perceived Barriers to Care Faced by Women Living with HIV in Latin America, China, Central/Eastern Europe, and Western Europe/Canada.

Generally, women are less likely than men to disclose their HIV status. This analysis examined the relationship between HIV disclosure and (1) perceived barriers to care and (2) quality of life (QoL) for women with HIV. The ELLA (EpidemioLogical study to investigate the popuLation and disease characteristics, barriers to care, and quAlity of life for women living with HIV) study enrolled HIV-positive women aged ≥18 years.

Barriers to access to care reported by women living with HIV across 27 countries.

Increased access to successful antiretroviral therapy (ART) is necessary in order to achieve an AIDS-free generation. Importantly, slightly over half of the people living with HIV are women. Small studies have described many barriers to accessing treatment and care among women living with HIV.

Reduced HIV symptoms and improved health-related quality of life correlate with better access to care for HIV-1 infected women: the ELLA study.

Introduction: Global HIV-1 prevalence is 35.3 million [1]; women comprise >50% of those infected. The majority of women may lack regular care and only one-fourth are virologically suppressed [2].

Inherited IL-12p40 deficiency: genetic, immunologic, and clinical features of 49 patients from 30 kindreds.

Autosomal recessive interleukin (IL)-12 p40 (IL-12p40) deficiency is a rare genetic etiology of mendelian susceptibility to mycobacterial disease (MSMD). We report the genetic, immunologic, and clinical features of 49 patients from 30 kindreds originating from 5 countries (India, Iran, Pakistan, Saudi Arabia, and Tunisia). There are only 9 different mutant alleles of the IL12B gene: 2 small insertions, 3 small deletions, 2 splice site mutations, and 1 large deletion, each causing a frameshift and leading to a premature stop codon, and 1 nonsense mutation.

Olfactory neuron-specific expression of A30P α-synuclein exacerbates dopamine deficiency and hyperactivity in a novel conditional model of early Parkinson's disease stages.

Mutations in the N-terminus of the gene encoding α-synuclein (α-syn) are linked to autosomal dominantly inherited Parkinson's disease (PD). The vast majority of PD patients develop neuropsychiatric symptoms preceding motor impairments. During this premotor stage, synucleinopathy is first detectable in the olfactory bulb (OB) and brain stem nuclei; however its impact on interconnected brain regions and related symptoms is still less far understood.

IL-12Rβ1 deficiency in two of fifty children with severe tuberculosis from Iran, Morocco, and Turkey.

Background And Objectives: In the last decade, autosomal recessive IL-12Rβ1 deficiency has been diagnosed in four children with severe tuberculosis from three unrelated families from Morocco, Spain, and Turkey, providing proof-of-principle that tuberculosis in otherwise healthy children may result from single-gene inborn errors of immunity. We aimed to estimate the fraction of children developing severe tuberculosis due to IL-12Rβ1 deficiency in areas endemic for tuberculosis and where parental consanguinity is common.

Methods And Principal Findings: We searched for IL12RB1 mutations in a series of 50 children from Iran, Morocco, and Turkey.

Revisiting human IL-12Rβ1 deficiency: a survey of 141 patients from 30 countries.

Interleukin-12 receptor β1 (IL-12Rβ1) deficiency is the most common form of Mendelian susceptibility to mycobacterial disease (MSMD). We undertook an international survey of 141 patients from 102 kindreds in 30 countries. Among 102 probands, the first infection occurred at a mean age of 2.

Clinical disease caused by Klebsiella in 2 unrelated patients with interleukin 12 receptor beta1 deficiency.

Patients with interleukin 12 (IL-12)p40 or IL-12 receptor β1 (IL12Rβ1) deficiencies are prone to develop infections caused by mycobacteria and salmonella; other infections have only been rarely observed. In this report we describe 2 unrelated patients with complete autosomal recessive IL12Rβ1 deficiency who suffered from sepsis attributable to Klebsiella pneumoniae. A Mexican boy suffered from disseminated bacille Calmette-Guérin disease and infections caused by K pneumoniae and Candida albicans and had a fatal outcome.

Determinants of contraceptive choice among women with HIV.

Objective: To examine factors associated with contraceptive choice among HIV-infected women.

Design: Data for this cross-sectional analysis were derived from baseline visits of 435 participants in an ongoing prospective study of contraception among HIV-infected women in Russia. Participants enrolled in one of four groups: combined oral contraceptives (COCs) along with condoms, depot medroxyprogesterone acetate (DMPA) along with condoms, copper intrauterine device (IUD) along with condoms, or condoms alone.

Histamine plays an essential regulatory role in lung inflammation and protective immunity in the acute phase of Mycobacterium tuberculosis infection.

The course and outcome of infection with mycobacteria are determined by a complex interplay between the immune system of the host and the survival mechanisms developed by the bacilli. Recent data suggest a regulatory role of histamine not only in the innate but also in the adaptive immune response. We used a model of pulmonary Mycobacterium tuberculosis infection in histamine-deficient mice lacking histidine decarboxylase (HDC(-/-)), the histamine-synthesizing enzyme.

Analysis of differentiation of stem/progenitor cells in tissue culture of neocortical primordium of mouse brain.

Differentiation of neural stem/progenitor cells from neocortical primordium of the brain from 14-day mouse embryos was studied by immunohistochemical methods during their culturing. Non-differentiated cells expressing nestin and vimentin persisted in freely floating neurospheres throughout the experiment. Glioblasts, neuroblasts, and differentiated neurons were found in neurospheres cultured in differentiating medium.

Mutations in STAT3 and IL12RB1 impair the development of human IL-17-producing T cells.

The cytokines controlling the development of human interleukin (IL) 17--producing T helper cells in vitro have been difficult to identify. We addressed the question of the development of human IL-17--producing T helper cells in vivo by quantifying the production and secretion of IL-17 by fresh T cells ex vivo, and by T cell blasts expanded in vitro from patients with particular genetic traits affecting transforming growth factor (TGF) beta, IL-1, IL-6, or IL-23 responses. Activating mutations in TGFB1, TGFBR1, and TGFBR2 (Camurati-Engelmann disease and Marfan-like syndromes) and loss-of-function mutations in IRAK4 and MYD88 (Mendelian predisposition to pyogenic bacterial infections) had no detectable impact.

[Prenatal ontogenesis of the human brain cortex temporal area].

Prenatal ontogenesis of temporal areas of the human cortex was studied. In the fetal cortex at the gestational age of 16-18 weeks three zones can be distinguished: marginal zone (eI layer), cortex plate and subplate. At 20-26 weeks cortex plate is divided into following layers: eII, eIII, eIV, eV and eVI, with "efferent" complex of layers being wider than "associative" one.

Impaired expression of perforin and granulysin in CD8+ T cells at the site of infection in human chronic pulmonary tuberculosis.

Protective immunity in tuberculosis is dependent on the coordinated release of cytolytic effector molecules from effector T cells and the subsequent granule-associated killing of infected target cells. In this study, we investigated the expression of cytolytic (perforin and granzyme A) and antimicrobial (granulysin) molecules at the single-cell level in cryopreserved lung tissue from patients with chronic, progressive tuberculosis disease. Quantification of protein-expressing cells was performed by in situ imaging, while mRNA levels in the infected tissue were analyzed by real-time PCR.

Tuberculosis in St. Petersburg and the Baltic Sea region.

Tuberculosis (TB) remains a global public health concern and challenges the national structures for infection control and health care, as well as international institutions, to develop and implement new strategies to control and combat this disease. In our report, we investigated the TB epidemiological situation in St. Petersburg and the countries around the Baltic Sea using national epidemiological statistics and epidemiological reports of international organizations, such as the WHO and Euro-TB.

Reactivation of tuberculosis by tumor necrosis factor neutralization.

Tumor necrosis factor (TNF) is required in the control of infection with Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis. TNF is essential and non-redundant for forming microbiocidal granulomas, and cannot be replaced by other members of the TNF family. We established a model of latent Mtb infection in mice, allowing investigation of the reactivation of latent Mtb as observed in patients receiving TNF-neutralizing therapy used in rheumatoid arthritis and Crohn's disease.

Detection of human perforin by ELISpot and ELISA: ex vivo identification of virus-specific cells.

The perforin (PFN) protein is essential for the elimination of target cells by cytotoxic T lymphocytes (CTL) and natural killer (NK) cells. The study of cells releasing PFN has been hampered by a lack of sensitive methods. We therefore produced PFN-reactive monoclonal antibodies (mAb) and developed capture enzyme-linked immunosorbent (ELISA) and enzyme-linked immunospot (ELISpot) assays.
