BACKGROUND: The prevalence of ischemic heart disease is high. Few recent studies have investigated the periods of sick leave of these patients. Our aim is to determine the length of sick leave after an acute coronary syndrome, its costs, associated factors and to assess the use of antidepressants and/or anxiolytics. METHODS: An observational study of a retrospective cohort of patients on sick leave due to ischemic heart disease in a health region between 2008-2011, with follow-up until the first return to work, death, or end of the study (31/12/2012)...

Subungual melanoma represents 20% of all melanomas in Hispanic population. Here, we report the outcome of 15 patients with in situ subungual melanoma treated with resection of the nail unit with a 5-mm margin without amputation, followed up for 55.93 ± 43.08 months. The most common complications included inclusion cysts and nail spicules. We found no evidence of local or distant recurrences at the last visit of our follow up. Functional outcome was good, with only one patient reporting persistent mild pain...

Sulfide mineral precipitation occurs at mid-ocean ridge (MOR) spreading centers, both in the form of plume particles and seafloor massive sulfide structures. A common constituent of MOR is the iron-bearing sulfide mineral pyrrhotite, which was chosen as a substrate for in-situ incubation studies in shallow waters of Catalina Island, CA to investigate the colonization of iron-oxidizing bacteria. Microbial community datasets were obtained from in-situ incubated pyrrhotite, allowing for direct comparison to microbial communities of iron-sulfides from active and inactive chimneys in deep-sea environments...

Dendritic cells (DCs) display the unique ability for cross-presenting antigens to CD8(+) T-cells, promoting their differentiation into cytotoxic T-lymphocytes (CTLs), which play a pivotal role in anti-tumor immunity. Emerging evidence points to dopamine receptor D3 (D3R) as a key regulator of immunity. Accordingly, we studied how D3R regulates DCs function in anti-tumor immunity. The results show that D3R-deficiency in DCs enhanced expansion of CTLs in vivo and induced stronger anti-tumor immunity. Co-culture experiments indicated that D3R-inhibition in DCs potentiated antigen cross-presentation and CTLs activation...

In this work, we report a simple fabrication method for microelectrodes on a polymethylmethacrylate substrate, using a low-cost laser platform based on a CD-DVD unit for direct rapid-prototyping. We used this laser microfabrication technique to etch any desired design on polymethylmethacrylate substrates to produce microchannels with controlled geometry, with a highly repeatable micron-scale resolution. Those shallow microchannels were then filled with a conductive paste of material of our choice that was converted into microelectrodes of desired shapes and geometries after drying...

OBJECTIVE: To examine the diagnostic accuracy of a previously developed model for prediction of preeclampsia (PE) by a combination of maternal factors and biomarkers at 11-13 weeks' gestation. METHODS: This was a prospective first-trimester multicenter study of screening for PE in 8,775 singleton pregnancies. A previously published algorithm was used for the calculation of patient-specific risk of PE in each patient. The detection rates (DR) and false positive rates (FPR) for delivery with PE at <32, <37 and ≥37 weeks were estimated and compared to those in the dataset used for development of the algorithm...

BACKGROUND: Endometrial cancer is the most common gynecologic malignancy, and its incidence and associated mortality are increasing. Despite the immediate need to detect these cancers at an earlier stage, there is no effective screening methodology or protocol for endometrial cancer. The comprehensive, genomics-based analysis of endometrial cancer by The Cancer Genome Atlas (TCGA) revealed many of the molecular defects that define this cancer. Based on these cancer genome results, and in a prospective study, we hypothesized that the use of ultra-deep, targeted gene sequencing could detect somatic mutations in uterine lavage fluid obtained from women undergoing hysteroscopy as a means of molecular screening and diagnosis...

Previous studies suggested that the aryl hydrocarbon receptor (AhR) contributes to mice reproduction and fertility. However, the mechanisms involved remain mostly unknown. Retrotransposon silencing by Piwi-interacting RNAs (piRNAs) is essential for germ cell maturation and, remarkably, AhR has been identified as a regulator of murine B1-SINE retrotransposons. Here, using littermate AhR(+/+) and AhR(-/-) mice, we report that AhR regulates the general course of spermatogenesis and oogenesis by a mechanism likely to be associated with piRNA-associated proteins, piRNAs and retrotransposons...

INTRODUCTION: Smoking is an important risk factor not only for cardiovascular and pulmonary diseases, but also for the progression of chronic kidney disease of different etiologies. Nodular glomerulosclerosis is a renal pathology pattern, which was described in different kidney conditions, especially diabetic nephropathy. A very rare association among smoking, hypertension and nodular mesangial glomerulosclerosis has been recently described. CASE PRESENTATION: In this paper, we present the case of a non-diabetic male patient referred to our Department for advanced chronic kidney disease and nephrotic syndrome...

Genetic leukoencephalopathies are a heterogeneous group of central nervous system disorders with white matter involvement. In a Finnish patient, we identified a novel homozygous disease-causing variant in HIKESHI, c.11G>C, p.(Cys4Ser), leading to hypomyelinating leukoencephalopathy with periventricular cysts and vermian atrophy. A founder Ashkenazi-Jewish disease-causing variant recently linked Hikeshi and its heat-shock protective function to leukoencephalopathy. In our patient, clinical features of lower limb spasticity, optic atrophy, nystagmus, and severe developmental delay were similar to reported patients...

Light chain-associated kidney compromise is frequent in patients with monoclonal gammopathies; it affects the glomeruli or the tubules, and its most common cause is multiple myeloma. It may develop after a kidney transplant due to recurrence of a preexisting multiple myeloma or it can be a de novo disease manifesting as graft dysfunction and proteinuria. A kidney biopsy is always necessary to confirm the diagnosis.We describe three cases of kidney graft dysfunction due to multiple myeloma in patients without presence of the disease before the transplant...

Primary sclerosing cholangitis (PSC) is a rare progressive disorder leading to bile duct destruction; ∼75% of patients have comorbid inflammatory bowel disease (IBD). We undertook the largest genome-wide association study of PSC (4,796 cases and 19,955 population controls) and identified four new genome-wide significant loci. The most associated SNP at one locus affects splicing and expression of UBASH3A, with the protective allele (C) predicted to cause nonstop-mediated mRNA decay and lower expression of UBASH3A...

INTRODUCTION: The use of noninvasive ventilation (NIV) in non-COPD patients with pneumonia is controversial due to its high rate of failure and the potentially harmful effects when NIV fails. The purpose of the study was to evaluate outcomes of the first ventilatory treatment applied, NIV or invasive mechanical ventilation (MV), and to identify predictors of NIV failure. METHODS: Historical cohort study of 159 non-COPD patients with pneumonia admitted to the ICU with ventilatory support...
