BACKGROUND: The aim of this study is to assess the value of contrast-enhanced ultrasound (CEUS) as a new non-invasive approach to locate the testicular area in which spermatogenesis is most likely to be found in non-obstructive azoospermic testes and to evaluate the accuracy of CEUS as a predictor of successful sperm retrieval. METHODS: CEUS was performed in 120 nonobstructive azoospermia (NOA) patients. Microdissection testicular sperm extraction (M-TESE) was performed on the best and poorest perfusion areas selected by CEUS and on conventional areas...

BACKGROUND: Auto-immune thrombotic thrombocytopenic purpura (TTP) is a morbid multi-organ disorder. Cardiac involvement not recognized in initial disease descriptions is a major cause of morbidity. Therapeutic plasma exchange (TPE) requires exposure to multiple plasma donors with risk of transfusion-transmitted infection (TTI). Pathogen inactivation (PI) with amotosalen-UVA, the INTERCEPT Blood System for Plasma (IBSP) is licensed to reduce TTI risk. METHODS: An open-label, retrospective study evaluated the efficacy of quarantine plasma (QP) and IBSP in TTP and defined treatment emergent cardiac abnormalities...

BAKGROUND: The aim of this study was to investigate the impact of body mass index (BMI) on the efficacy of endocrine therapy in postmenopausal women with metastatic hormone receptor breast cancer (HR+BC) as well as to identify if the potential difference in efficacy was associated with Fulvestrant only or both aromatase inhibitors (AIs) and Fulvestrant. METHODS: A consecutive cohort of postmenopausal women with HR+metastatic breast cancer that have received endocrine therapy including Fulvestrant as a metastatic treatment strategy at the Departments of Oncology in Eskilstuna and Uppsala, Sweden, between 2008 and 2016 were identified...

BACKGROUND: Chest radiographs are used for diagnosis and severity assessment in tuberculosis (TB). The extent of disease as determined by smear grade and cavitation as a binary measure can predict 2-month smear results, but little has been done to determine whether radiological severity reflects the bacterial burden at diagnosis. METHODS: Pre-treatment chest x-rays from 1837 participants with smear-positive pulmonary TB enrolled into the REMoxTB trial (Gillespie et al...

Thrombotic thrombocytopenic purpura (TTP) is primarily caused by deficiency of ADAMTS13 within the blood stream due to either genetic defects or presence of inhibitory autoantibodies. Preclinical and clinical studies suggest that enzyme replacement therapy with recombinant human ADAMTS13 protein (rhADAMTS13) is effective and safe in treatment of TTP. However, frequent dosing would be required due to the relatively short half-life of rhADAMTS13 in circulation as well as the presence of inhibitory autoantibodies that collectively result in the poor pharmacological profile of rhADAMTS13...

INTRODUCTION: Pectoral Nerves Block (PECS) and Serratus Plane Block (SPB) have been used to treat persistent post-surgical pain after breast and thoracic surgery, however they cannot block the internal mammary region, so a residual pain may occur in that region. Parasternal block (PSB) and Thoracic Transversus Plane Block (TTP) anesthetize the anterior branches of T2-6 intercostal nerves thus they can provide analgesia to the internal mammary region. METHODS: We describe a 60-year-old man suffering from right post thoracotomy pain syndrome with residual pain located in the internal mammary region after a successful treatment with PECS and SPB We performed a PSB and TTP and hydrodissection of fascial planes with triamcinolone and Ropivacaine...

Although maternal nutrition may impact fecundity, associations between preconception micronutrients and time to pregnancy (TTP) has not been examined. We assessed the relationship between preconception fat-soluble micronutrient concentrations and TTP among women with 1-2 prior pregnancy losses. This is a prospective cohort study of 1,228 women set in the EAGeR Trial (US, 2007-2011), which assessed the effect of preconception-initiated daily low dose aspirin on reproductive outcomes. We measured preconception zeaxanthin, cryptoxanthin, lycopene, α- and β-carotene, and α- and γ-tocopherol in serum...

Background: Several recent randomized controlled trials (RCTs) in hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer (MBC) have demonstrated significant improvements in progression-free survival (PFS); however, few have reported improvement in overall survival (OS). The surrogacy of PFS or time to progression (TTP) for OS has not been formally investigated in HR+, HER2- MBC. Methods: A systematic literature review of RCTs in HR+, HER2- MBC was conducted to identify studies that reported both median PFS/TTP and OS...

Renal and neurological involvements are frequently seen in thrombotic thrombocytopenic purpura (TTP). Cardiac involvement, however, has been rarely reported. In this article, we present 2 cases of myocardial infarction in patients with TTP. In the first case, a young man presented with non-ST-segment elevation myocardial infarction that resolved promptly with plasmapheresis. The second patient developed ST-segment elevation myocardial infarction early in the course of the disease and died before plasmapheresis could be initiated...

BACKGROUND: Current guideline recommendations for immunosuppression reduction after diagnosis of posttransplant lymphoproliferative disorder (PTLD) include stopping antimetabolites, reducing calcineurin inhibitors and maintaining corticosteroids. However, the effect of immunosuppression on PTLD relapse risk after up-to-date therapy is unclear. METHODS: This is a retrospective analysis of immunosuppression, patient baseline characteristics and relapse risk measured as landmark time to progression (TTP) starting 1 year after start of therapy in 159 patients with B cell PTLD after solid organ transplantation treated in the prospective, international, multicenter PTLD-1 trials with either sequential treatment (rituximab followed by CHOP chemotherapy) or risk-stratified sequential treatment (rituximab followed by rituximab or R-CHOP immunochemotherapy)...

Malignant hypertension can cause thrombotic microangiopathy (TMA) characterized by hemolytic anemia and thrombocytopenia. On the other hand, severe hypertension is sometimes associated with hemolytic uremic syndrome (HUS) or thrombotic thrombocytopenic purpura (TTP). Distinguishing these entities is important because of therapeutic implications. Plasmapheresis should be initiated as soon as possible if we are dealing with TTP. We describe the case of a 30-year-old man referred to our hospital with malignant hypertension, severe renal failure and TMA: haemoglobin=9g/dL, total bilirubin=0...

BACKGROUND: Human exposure to bisphenol A (BPA) is common. The reproductive toxicity of BPA has been well characterized. However, the impact of BPA exposure on fecundability in healthy women is less clear, and evidence from eastern countries is lacking. OBJECTIVES: We aimed to prospectively assess the associations of BPA with female fecundability, as measured by time to pregnancy (TTP). METHODS: From 2013 to 2015, we included 700 Chinese couples attempting pregnancy in two preconception care clinics and followed for 12 months or until a pregnancy occurred...

Assessing therapy response of breast cancer bone metastases is challenging. In retrospective studies, serial 18 F-FDG PET was predictive of time to skeletal related events (tSRE) and time-to-progression (TTP). 18 F-NaF PET improves bone metastasis detection compared to bone scans. We prospectively tested 18 F-FDG PET and 18 F-NaF PET to predict tSRE, TTP, and overall survival (OS) in patients with bone-dominant metastatic breast cancer (BD MBC). Methods: Patients with BD MBC were imaged with 18 F-FDG PET and 18 F-NaF PET prior to starting new therapy (scan1) and again at a range of times centered around approximately 4 months later (scan2)...

BACKGROUND AND PURPOSE: Chronic hemodynamic impairment in high-grade carotid occlusive disease is thought to cause microstructural abnormalities that might be subclinical or lead to subtle symptoms including cognitive impairment. Quantitative MR imaging allows assessing pathologic structural changes beyond macroscopically visible tissue damage. In this study, high-resolution quantitative T2 mapping combined with DSC-based PWI was used to investigate quantitative T2 changes as a potential marker of microstructural damage in relation to hemodynamic impairment in patients with unilateral high-grade carotid occlusive disease...

We describe an unusual in-plane type of porphyrin core distortion, tetragonal elongation (TE), observed experimentally in diboron porphyrins. The vibrational spectra of several of these complexes exhibit shifts that we have assigned to this TE distortion by comparing experimental spectra with DFT computational findings. The influence of TE in porphyrin systems was isolated using DFT analysis of the well-known model compounds Ni(II)porphine and Zn(II)porphine, with the macrocycle ring constrained to eliminate the influence of out-of-plane (OOP) distortions...

Thrombotic thrombocytopenic purpura (TTP) is a part of a spectrum of thrombotic microangiopathy syndromes which are mainly characterized by platelet aggregation causing microangiopathic hemolytic anemia, thrombocytopenia and microvascular occlusion. In literature, very few cases expressing a direct association between pre-existing Grave's disease and TTP have been described. A 37-year-old African-American woman with past medical history of Grave's disease and polysubstance abuse who presented with complaints of dyspnoea at rest and chest pain was diagnosed to have TTP on further evaluation...

OBJECTIVE: The aim of this study was to determine whether the apolipoprotein A-1 (apoA-1) mimetic peptide ELK-2A2K2E regulates inflammatory cytokine expression via activating the ATP-binding cassette transporter A1 (ABCA1)-janus kinase 2 (JAK2)-signal transducer and activator of transcription 3 (STAT3)- tristetraprolin (TTP) signaling pathway in THP-1 macrophage-derived foam cells. METHODS AND RESULTS: The cells were treated with the apoA-1 mimetic peptide ELK-2A2K2E at different concentrations (0, 20, 40, 80 μg/ml) or incubated with ELK-2A2K2E (40 μg/ml) for different times (0, 6, 12, 24 h)...

STUDY QUESTION: Is preconception dietary intake associated with reduced fecundity as measured by a longer time to pregnancy (TTP)? SUMMARY ANSWER: Lower intake of fruit and higher intake of fast food in the preconception period were both associated with a longer TTP. WHAT IS KNOWN ALREADY: Several lifestyle factors, such as smoking and obesity, have consistently been associated with a longer TTP or infertility, but the role of preconception diet in women remains poorly studied...
