Aims: To explore whether the transfer of very poor quality (VPQ) embryos is associated with an increase in congenital malformations or perinatal problems.
Methods: In this retrospective case-control study, 74 children conceived by in vitro fertilization (IVF) and/or intracytoplasmic sperm injection (ICSI) resulting exclusively from the transfer of VPQ embryos were compared with 1,507 children born after the transfer of top morphological quality (TQ) embryos over the same period of time in the same centers.
Results: The prevalence of birth defects in children resulting from VPQ embryos was 1.
Background: Dementia is a multi-etiologic syndrome characterized by multiple cognitive deficits but not always by the presence of cognitive impairment. Cognitive impairment is associated with multiple non-modifiable risk factors but few modifiable factors. Epidemiologic studies have shown an association between periodontitis, a potentially modifiable risk factor, and cognitive impairment.

We investigate whether hypotonic swelling promotes nitric oxide (NO) release in cardiomyocytes, and whether it impacts on swelling-induced contractile dysfunction.
Methods And Results: Superfusing rat cardiomyocytes with a hypotonic solution (HS; 217 mOsm), increased cell volume, reduced myocyte contraction and Ca(2+) transient, and increased NO-sensitive 4-amino-5-methylamino-2',7'-difluorofluorescein diacetate (DAF-FM) fluorescence.
Background: Law enforcement can shape HIV risk behaviours and undermine strategies aimed at curbing HIV infection. Little is known about factors that increase vulnerability to police victimization in Mexico. This study identifies correlates of police or army victimization (i.

Methods: We prospectively obtained liver stiffness measurements by transient elastography in a cohort of 154 HCV/HIV-coinfected patients, mostly Caucasian men on suppressive antiretroviral treatment, with the aim of determining the risk for liver stiffness measurement (LSM) increase and to identify the predictive factors for liver fibrosis progression. To evaluate LSM trends over time, a linear mixed regression model with LSM level as the outcome and duration of follow-up in years as the main covariate was fitted.
Several studies have shown the importance of adherence to highly active antiretroviral therapy (HAART) in achieving HIV-1 suppression. However, most have focused on naïve patients and do not assess the impact of HAART on viral load (VL). Our aim was to evaluate the effectiveness of an adherence program in a cohort of multitreated and poorly adherent patients.

Influenza and meteorological factors have been associated with increases in the incidence of invasive pneumococcal disease (IPD). However, scant data regarding the impact of influenza and the environment on the clinical presentation of IPD are available. An observational study of all adults hospitalized with IPD was performed between 1996 and 2012 in our hospital.

Horizontal alignment during synthesis of single-walled carbon nanotubes has been found experimentally along certain directions of well-defined quartz surfaces. The reasons for such alignment are here examined using first-principles computational analysis, as a function of structure and chemistry of the specific exposed facet, presence and location of OH and H functional groups, and degree of hydration of the surface. It is found that selective functionalization of low-coordinated surface sites may cause exposure of low-coordinated Si atoms that bond strongly to nanotube walls.

Study Design: This was a prospective single-center cohort study of 200 women with a consecutive cohort of 100 pregnant women with a breech presentation at term who were administered intravenous fluid therapy with 2 L of hypotonic saline before the version attempt, compared to a control cohort of 100 pregnant women not given hydration treatment.
Results: The mean increase in the amniotic fluid index (AFI) after intravenous maternal hydration was 3.
Unsafe injection practices significantly increase the risk of hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infection among injection drug users (IDUs). We examined individual and socio-environmental factors associated with unsafe injection practices in young adult IDUs in San Diego, California. Of 494 IDUs, 46.

Objective: To compare the effect on the cervical sagittal balance of 2 AIS correction constructs, namely, all pedicle screws and hybrid instrumentation using hooks and pedicle screws.
Summary Of Background Data: An inverse relationship between cervical and thoracic kyphosis in AIS has been found in pediatric patients after concave derotation using hybrid constructs with pedicle screws and hooks.

The clinical response of 18 enrolled patients was compared to the evolution of 31 ALS out-patients, carefully paired by age, gender, evolution rate and time of the disease, who never received treatment with lithium and/or valproate. The ALS functional rating scale, revised version (ALSFRS-R), was applied at baseline, 1 month, and every 4 months until the outcome (death or an adverse event).

Summary Of Background Data: Although the rate of misplaced screws is relatively high, few patients have neurological impairment. This suggests that a significant degree of medullary displacement and/or compression is necessary to produce neurophysiological changes.
Background: The incidence of invasive pneumococcal disease (IPD) appears to be associated with influenza. The objectives of this study were to evaluate the changes in IPD incidence and clinical data as well as the trends in Streptococcus pneumoniae serotype distribution in adults during the peak period of the 2009 influenza A H1N1 pandemic (IAP).
Methods: We performed a prospective multicentre study on IPD from week 42 to 48, 2009 in an area of Barcelona (Catalonia, Spain) covering 1,483,781 adult inhabitants.
An 86-year-old male with history of metastatic prostate carcinoma and hypertension was admitted due to acute onset dyspnea and lower extremity pain and swelling. Transthoracic echocardiography revealed a large right atrial thrombus extending in to the right ventricle. Within 12 h, the patient developed severe hypoxemia, tachypnea with sustained hypotension and cardiogenic shock due to presumed massive pulmonary embolism.

To date, the efficiency of methods to increase the tolerance of the cord to displacement and the influence of hypotension on this tolerance is yet to be assessed.
Purpose: The objective of this study was to determine the limits of cord displacement before the disappearance of neurophysiologic signals.
Objective: To determine if external cephalic version (ECV) can be performed with safety and efficacy in women with previous caesarean section.
Design: Prospective comparative cohort study.
Setting: Cruces University Hospital (Spain).
Background: The 13-valent pneumococcal conjugate vaccine (PCV13) has recently been approved for use in immunocompromised adults. However, it is unclear whether there is an association between specific underlying conditions and infection by individual serotypes. The objective was to determine the prevalence of serotypes covered by PCV13 in a cohort of patients with invasive pneumococcal disease of respiratory origin and to determine whether there are specific risk factors for each serotype.

Recent in vitro studies have shown that PACAP 6-38, a pituitary adenylate cyclase-activating polypeptide (PACAP) fragment, could act as a competitive antagonist against CARTp 55-102 on a common CARTp-sensitive receptor structure. Here, we show for the first time in vivo that the reduction in solid food intake induced by exogenous CARTp 55-102 (0.
