Reproductive tract infections have long been hypothesized to increase fibroid risk. Few studies have been conducted, even for the common infection, genital Chlamydia trachomatis (gCT), and only with self-reported gCT data. Our investigation used micro-immunofluorescence serology for gCT to characterize past exposure. We used cross-sectional enrollment data from a prospective fibroid study in the Detroit, Michigan area; ultrasound examinations systematically screened for fibroids. Participants were African-American women ages 23-34 (recruited 2010-2012)...

Non-alcoholic fatty liver disease (NAFLD) may be one of the important causes of cryptogenic hepatocellular carcinoma (HCC). NAFLD-related HCCs (NAFLD-HCCs) have the following clinical features: high body mass index, deranged lipid profiles, diabetes mellitus, hypertension, and metabolic syndrome. Among them, obesity, diabetes mellitus, and high Fe contents in the liver are risk factors of developing HCC in patients with NAFLD. Inflammatory cytokines, adipokines, insulin like growth factor-I, and lipotoxicity are intermingled and may cross react with each other to develop HCC...

Autophagy is involved in modulating tumor cell motility and invasion, resistance to epithelial-to-mesenchymal transition, anoikis, and escape from immune surveillance. We have previous shown that SAHA is capable to induce several apoptosis and autophagy-related gene expression in breast cancers. However, the exact mechanisms of autophagy activation in this context have not been fully identified. Our results showed that the expression and the activity of Cathepsin B (CTSB), one of the major lysosomal cysteine proteases, were significantly increased in MDA-MB- 231 and MCF-7 cells upon SAHA treatment...

Wild populations of the critically endangered woylie (Bettongia penicillata) recently declined by 90% in southwest Western Australia. Increased predation is the leading hypothesis for decline, but disease may be playing a role increasing susceptibility to predation. To explore this possibility, we surveyed woylie populations in the wild, in captivity and in a predator-free sanctuary for exposure to, and infection with, four known pathogens of macropods: herpesviruses, Wallal and Warrego orbiviruses, and Toxoplasma gondii...

Sporadic Salmonella outbreaks with varying clinical presentations have been on the rise in various parts of Uganda. The sources of outbreaks and factors underlying the different clinical manifestation are curtailed by paucity of information on Salmonella genotypes and the associated virulence genes. This study reports molecular diversity of Salmonella enterica and their genetic virulence profiles among human and animal isolates. Characterization was done using Kauffman-White classification scheme and virulence genes analysis using multiplex PCR...

BACKGROUND AND PURPOSE: Poststroke functional outcome is critical to stroke survivors. We sought to determine whether adherence to current stroke performance measures is associated with better functional outcome 90 days after an ischemic stroke. METHODS: Utilizing the Brain Attack Surveillance in Corpus Christi cohort, we examined adherence to 7 ischemic stroke performance measures from February 2009 to June 2012. Adherence to the measures was analyzed in aggregate using a binary defect-free score and an opportunity score, representing the proportion of eligible measures met...

Kaposi sarcoma (KS) is a malignancy of viral etiology whose course ranges from cutaneous limited lesions to fulminant disease with multi-organ involvement. Four clinical variants of the disease exist: classic, endemic, iatrogenic, and epidemic. Iatrogenic and epidemic variants of Kaposi sarcoma develop in the setting of immune suppression. Transplant recipients who develop iatrogenic KS typically demonstrate improvement of lesions following de-escalation of immunosuppressive therapy. Similarly, HIV-infected patients who begin highly active antiretroviral therapy (HAART) experience immune reconstitution, which can induce KS regression...

Background: Multidrug-resistant tuberculosis (MDR TB) is an important global public health threat, but accurate estimates of MDR TB burden among children are lacking. Methods: We analyzed demographic, clinical and laboratory data for newly-diagnosed pediatric (<15 years) TB cases reported to the US National TB Surveillance System (NTSS) during 1993-2014. MDR TB was defined as culture-confirmed TB disease with resistance to at least isoniazid and rifampicin. To ascertain potential under-estimation of pediatric MDR TB, we surveyed high burden states for clinically-diagnosed cases treated for MDR TB...

During recent years, various mumps outbreaks have occurred among populations vaccinated for mumps worldwide. In Italy, improving routine coverage with two doses of measles, mumps and rubella (MMR) vaccine is one of the key strategies to eliminate measles and rubella. To monitor the effect of the vaccination programme on the population, the surveillance of these vaccine-preventable diseases has been implemented. This provided the opportunity to evaluate the accuracy of the clinical diagnosis of those diseases, including mumps...

REVIEW
Mohamed A Kharfan-Dabaja, Mahmoud Aljurf
Hematopoietic cell transplantation (HCT), particularly allogeneic HCT, is a complex and a high-risk procedure requiring expertise to manage potential treatment complications. Published data supports the value of quality management systems in improving post-transplant outcomes; however, there are no universally established, or agreed upon, criteria to assess adequacy of training of physicians, transplant or nontransplant, and supporting staff, among others. It is of paramount importance for transplant centers to identify the needed area(s) of expertise in order to seek appropriate training for their staff...

In Chile, high cost treatments required by selected medical conditions are financed by the State, according to Law 20.850. A bylaw under discussion by the Senate regulates clinical trials, posing complex issues that will endanger local interest in front-line research: 1) The exclusive and mandatory control bestowed to the Institute of Public Health during all stages of the trials and also the surveillance of institutions performing clinical trials, overriding their Clinical Research Review Boards; 2) The 10 year period during which any adverse event is assumed to have been caused by the medication or devise evaluated by the trial, unless the contrary is proven in a judicial process; 3) Individuals submitted to the trials are entitled to free post trial access to the treatment received during the study, financed by the trial supporting entities and as long as the drug or devise is considered to be useful...

BACKGROUND: In recent decades, the world has witnessed unprecedented progress in child survival. However, our knowledge of what is killing nearly 6 million children annually in low- and middle-income countries remains poor, partly because of the inadequacy and reduced precision of the methods currently utilized in these settings to investigate causes of death (CoDs). The study objective was to validate the use of a minimally invasive autopsy (MIA) approach as an adequate and more acceptable substitute for the complete diagnostic autopsy (CDA) for pediatric CoD investigation in a poor setting...

PURPOSE OF REVIEW: To investigate the association between obesity and prostate cancer (PCa). RECENT FINDINGS: Obesity has been proposed to be involved in the pathogenesis of PCa through different biological mechanisms that include deregulation of the insulin axis, sex hormone secretion, adipokines signaling, and oxidative stress. Hypertrophic peritumoral adipocytes may also facilitate the local spread of PCa through the chemo-attraction of tumor cells. Clinical studies demonstrate that obesity might have clinical implications also in disease detection and management...

BACKGROUND: The risk of pacemaker pocket infections (PPIs) is rare with good antisepsis techniques and use of advanced antibiotics. However, injudicious antibiotic usage leads to the rise of multidrug-resistant bacteria, which may cause PPI. Few reports exist about the microbial spectrum of the PPI from our country, prompting us to study the same. METHODS: We conducted this retrospective observational study for 3 years (January 2013-February 2016) from all the patients with PPI...

Type 2 diabetes correlates with clinical events after the implantation of a second-generation drug-eluting stent (DES). The rate and prognostic value of stent fracture (SF) in patients with diabetes who underwent DES implantation remain unknown. A total of 1160 patients with- and 2251 without- diabetes, who underwent surveillance angiography at 1 year after DES implantation between June 2004 and August 2014, were prospectively studied. The primary endpoints included the incidence of SF and a composite major adverse cardiac event [MACE, including myocardial infarction (MI), cardiac death, and target-vessel revascularization (TVR)] at 1-year follow-up and at the end of follow-up for overall patients, and target lesion failure [TLF, including cardiac death, target vessel myocardial infarction (TVMI) and target lesion revascularization (TLR)] at the end of study for SF patients...
