BACKGROUND AND AIMS: Elevated circulating levels of fibroblast growth factor 21 (FGF21) are associated with multiple cardiovascular disease (CVD) risk factors and incident events. Previous small cross-sectional studies, mainly in Chinese populations, have suggested FGF21 may play a role in the development of atrial fibrillation (AF). We therefore investigated the relationship of FGF21 levels with incident AF in participants free of clinically apparent CVD at baseline in a large, multi-ethnic cohort...

Erroneous DNA repair by heterologous recombination (Ht-REC) is a potential threat to genome stability, but evidence supporting its prevalence is lacking. Here we demonstrate that recombination is possible between heterologous sequences and that it is a source of chromosomal alterations in mitotic and meiotic cells. Mechanistically, we find that the RTEL1 and HIM-6/BLM helicases and the BRCA1 homolog BRC-1 counteract Ht-REC in Caenorhabditis elegans, whereas mismatch repair does not. Instead, MSH-2/6 drives Ht-REC events in rtel-1 and brc-1 mutants and excessive crossovers in rtel-1 mutant meioses...

AIM: The aim of this study was to investigate fathers' emotional experiences of their infant's preterm birth and subsequent stay in neonatal intensive care unit. BACKGROUND: When a baby is born preterm, there is also the premature interruption of the process of preparation for fatherhood. As a result, the impact on fathers of the preterm birth can bring negative consequences for the development of father-infant relationship. DESIGN: A multi-method approach was used which included ethnographic observation, semi-structured interviews with fathers, a self-report questionnaire and clinical information between September 2015-March 2017...

Consumption of fish containing ciguatera toxins or ciguatoxins (CTXs) causes ciguatera fish poisoning (CFP). In some patients, CFP recurrence occurs even years after exposure related to CTXs accumulation. Pacific CTX-1 (P-CTX-1) is one of the most potent natural substances known that causes predominantly neurological symptoms in patients; however, the underlying pathogenies of CFP remain unknown. Using clinically relevant neurobehavioral tests and electromyography (EMG) to assess effects of P-CTX-1 during the 4 months after exposure, recurrent motor strength deficit occurred in mice exposed to P-CTX-1...

In 1891 Hans Chiari described a group of congenital hindbrain anomalies, which were eventually named after him. He classified these malformations into three types (Chiari malformations I, II, and III), and four years later added the Chiari IV malformation. However, numerous reports across the literature do not seem to fit Chiari's original descriptions of these malformations, so researchers have been encouraged to propose new classifications to encompass these variants (e.g., Chiari 0, Chiari1.5, and Chiari 3...

This paper deals primarily with the identification of an inaccurately catalogued alchemical poem attributed to the famous Umayyad prince Khālid b. Yazīd (d. 705), edited, translated, and commented upon here for the first time. The paper also addresses the authenticity of Khālid's interest in alchemy and connects that interest to the need of the early Islamic empire to develop its own gold coinage as a sign of political independence from Byzantine coinage that was up till then the currency of the lands occupied by early Muslims in the regions of modern-day Egypt and Syria...

BACKGROUND: Perinatal asphyxia (PA) occurs in about 2 to 10 per 1000 live full-term births. Although neonatal epileptic seizures are observed in up to 60% of cases, PA may mimic or subtend other conditions. Hypoxia related brain injury is particularly relevant, as it may have permanent effects on neuropsychomotor development. Antepartum obstetric conditions, may, in turn, lead to hypoxic-ischemic damage to the fetus and the newborn, often underlying PA. Herein, a case of PA that hid and triggered signs and symptoms of Glutaric Aciduria type I (GA-I), is reported...

Authors have proposed a concept of guidelines for applying the ambulatory complex cardiovascular rehabilitation (ACCVR) into the clinical practice in Slovakia. As a background they have used an actual cardiovascular mortality and morbidity data from home country and abroad as well. They emphasize the non-optimal situation in this aspect which may not be solved by the increasing supporting the invasive revascularization methods and by the intensifying pharmacotherapy only, because the favourable effects of these procedures is timely missing if it is not accompanied by the therapeutic lifestyle changes...

Purpose: The delayed diagnosis of colorectal cancer (CRC) may be attributable to sociodemographic characteristics, to aspects of tumour histopathology or to the functioning of the health system. We seek to determine which of these factors most influences prolonged patient-attributable delay (PPAD) in the diagnosis and treatment of CRC. Materials and method: A prospective, multicentre observational study was conducted in 22 Spanish hospitals. In total, 1,785 patients were recruited to the study between 2010 and 2012 and underwent elective or urgent surgery...

Attempted murder by repeated poisoning is quite rare. The authors describe the case of a 62-year-old man who was admitted to an intensive care unit (ICU) for neurological disturbances complicated by inhalation pneumopathy. He presented a loss of consciousness while his wife was visiting him at the ICU (H0). Forty-eight hours later (H48), police officers apprehended the patient's wife pouring a liquid into his fruit salad at the hospital. Toxicological analyses of a blood sample and the infusion equipment (H0), as well as the fruit salad and its container (H48), confirmed the attempted poisoning with cyamemazine (H0) and hydrochloric acid (H48)...

An 18 year old boy attended a dermatology clinic outside our hospital and diagnosed with psoriasis. His skin lesions over both ankles (Fig. 1) did not improve at all with potent local steroids twice for 3 months, then 3 times daily for another 3 months. His dermatologist talked to him about using methotrexate and asked for liver function tests before starting the systemic therapy. His ALT and AST were doubled. The patient came to our Hepatology clinic worried about his elevated liver enzymes. We asked for viral markers...

I recently diagnosed my first adolescent patient with new-onset HIV. As a primary care pediatrician, these cases are rare. I cried with the shock of the initial diagnosis, just as the patient did when I told him. One of my first thoughts was how could I have served him better. He had been inconsistent with condom use, and had several partners. I had encouraged safe sex practices, told him to talk to his partners about pregnancy prevention, and screened for sexually transmitted disease nearly every time he came into my office...

Sara Ajina, Holly Bridge
Residual vision, or blindsight, following damage to the primary visual cortex (V1) has been investigated for almost half a century. While there have been many studies of patients with unilateral damage to V1, far fewer have examined bilateral damage, mainly due to the rarity of such patients. Here we re-examine the residual visual function and underlying pathways of previously studied patient SBR who, as a young adult, suffered bilateral damage restricted to V1 which rendered him cortically blind. While earlier work compared his visual cortex to healthy, sighted participants, here we consider how his visual responses and connections compare to patients with unilateral damage to V1 in addition to sighted participants...

Walter Harris (1647-1732) was a very interesting figure in paediatrics during the second half of the 17th century and first half of 18th century. He was born in Gloucester, England, and studied medicine at Bourge, France, in 1675. He continued his medical studies at Cambridge. He became physician in ordinary to Charles II (1630-1685) in 1683 and later to William III (1650-1702), accompanying him to Holland (1). This article is protected by copyright. All rights reserved.

Himeic acid A, produced by the marine fungus Aspergillus japonicus MF275, is a specific inhibitor of the ubiquitin-activating enzyme E1 in the ubiquitin-proteasome system. To elucidate the mechanism of himeic acid biosynthesis, we first carried out feeding experiments with labeled precursors. The long fatty acyl side chain attached to the pyrone ring was confirmed to be of polyketide origin, while the amide substituent was found to be derived from leucine. These results suggest that a polyketide synthase-non-ribosomal peptide synthase (PKS-NRPS) is involved in himeic acid biosynthesis...

BACKGROUND: In a highly technical civilization like ours, in which the interest in human communication transcends academic barriers and clinical practice, it seems necessary to look back to Ruesch's work in psychiatry. The main reason of it rests upon the idea that he was one of the few truly outstanding clinicians, researchers, and theoretical in the field of normal and abnormal communication. In fact, he did not only present a wealth of observational and clinical data; more importantly, he used these data to formulate creative hypotheses about the conflict between man and other human beings...
