Abstract Background Pain modulation is a critical function of the nociceptive system that includes the ability to engage descending pain control systems to maintain a functional balance between facilitation and inhibition of incoming sensory stimuli. Dysfunctional pain modulation is associated with increased risk for chronic pain and is characteristic of fibromyalgia (FM). Catastrophizing is also common in FM. However, its influence on pain modulation is poorly understood. Objective To determine the role of catastrophizing on central nervous system processing during pain modulation in FM via examining brain responses and pain sensitivity during an attention-distraction paradigm. Methods Twenty FM patients and 18 healthy controls (CO) underwent functional magnetic resonance imaging while receiving pain stimuli, administered alone and during distracting cognitive tasks. Pain ratings were assessed after each stimulus. Catastrophizing was assessed with the Pain Catastrophizing Scale (PCS). Results The ability to modulate pain during distraction varied among FM patients and was associated with catastrophizing. This was demonstrated by significant positive relationships between PCS scores and pain ratings (P < 0.05) and brain responses in the dorsolateral prefrontal cortex (P < 0.01). Relationships between catastrophizing and pain modulation did not differ between FM and CO (P > 0.05). Conclusions FM patients with higher levels of catastrophizing were less able to distract themselves from pain, indicative of catastrophizing-related impairments in pain modulation. These results suggest that the tendency to catastrophize interacts with attention-resource allocation and may represent a mechanism of chronic pain exacerbation and/or maintenance. Reducing catastrophizing may improve FM symptoms via improving central nervous system regulation of pain.

Abstract Background Haemophilia A is an X-linked genetic condition which manifests itself mainly in male children in the first 2 years of life, during gross motor skill development. This disorder is rare in females. The clinical manifestation of severe haemophilia in preterm infants poses a great challenge to the therapeutic team. As extreme prematurity is linked to an increased risk of central nervous system or gastrointestinal bleeding, a well-informed and balanced treatment from the first days of life is crucial to prevent long-term damage. Haemophilia is most commonly caused by inheriting defective genes, and can also be linked to skewed X inactivation and Turner syndrome. The coincidental occurrence of haemophilia A and Turner syndrome is extremely rare, with only isolated cases described to date. Hence, a multidisciplinary approach is needed. Case presentation The authors report on a preterm girl (gestational age 28 weeks) diagnosed with haemophilia and Turner syndrome. The first manifestation of haemophilia was prolonged bleeding from injection sites on the second day of life. Indeterminate aPTT and factor VIII level < 1% confirmed the diagnosis of haemophilia A. Dysmorphic features which did not match the typical clinical picture of haemophilia, the female sex, and a negative paternal family history led to the diagnosis of Turner syndrome. While in hospital, the girl received multiple doses of recombinant factor VIII in response to prolonged bleedings from the injection sites and from a nodule on the girl’s head, and before and after retinal laser photocoagulation. No central nervous system or abdominal cavity bleeding was observed. The substitutive therapy was complicated by the development of factor VIII inhibitor (anti-factor VIII (FVIII) antibodies). Treatment was continued with recombinant factor VIIa. This article aims at demonstrating the complexity of the diagnostics and treatment of a preterm child with two genetic disorders. Conclusions Haemophilia should always be considered in the differential diagnosis of prolonged bleeding, even in patients with a negative family history. In the case of coinciding atypical phenotypic features, further diagnostics for another genetic disease are recommended. Infant care should follow current care standards, while considering certain individual features.

Maternal Overnutrition

Ample evidence from epidemiological studies has linked maternal obesity with metabolic disorders such as obesity, cardiovascular disease, and diabetes in the next generation. Recently, it was also shown that maternal obesity has long-term effects on the progeny’s central nervous system. However, very little is known regarding how maternal overnutrition may affect, in particular, the cognitive abilities of the offspring. We reported that first-generation offspring exposed to a maternal high-fat diet (MHFD) displayed age-dependent cognitive deficits. These deficits were associated with attenuations of amino acid levels in the medial prefrontal cortex and the hippocampus regions of MHFD offspring. Here, we tested the hypothesis that MHFD in mice may induce long-term cognitive impairments and neurochemical dysfunctions in the second and third generations. We found that MHFD led to cognitive disabilities and an altered response to a noncompetitive receptor antagonist of the N-Methyl-D-aspartic acid (NMDA) receptor in adult MHFD offspring in both second and third generations in a sex-specific manner. Our results suggest that maternal overnutrition leads to an increased risk of developing obesity in subsequent generations as well as to cognitive impairments, affecting learning and memory processes in adulthood. Furthermore, MHFD exposure may facilitate pathological brain aging which is not a consequence of obesity. Our findings shed light on the long-term effects of maternal overnutrition on the development of the central nervous system and the underlying mechanisms which these traits relate to disease predisposition.

This study was designed to document the systemic inflammatory response syndrome (SIRS) and multiple-organ dysfunction syndrome (MODS) in dogs with complicated babesiosis, and to assess their impact on outcome. Ninety-one cases were evaluated retro-spectively for SIRS and 56 for MODS. The liver, kidneys, lungs, central nervous system and musculature were assessed. Eighty-seven percent of cases were SIRS-positive. Fifty-two percent of the cases assessed for organ damage had single-organ damage and 48 % had MODS. Outcome was not significantly affected by either SIRS or MODS, but involvement of specific organs had a profound effect. Central nervous system involvement resulted in a 57 times greater chance of death and renal involvement in a 5-fold increased risk compared to all other complications. Lung involvement could not be statistically evaluated owing to co-linearity with other organs, but was associated with high mortality. Liver and muscle damage were common, but did not significantly affect outcome. There are manysimilarities between the observations in this study and previous human and animal studies in related fields, lending additional support to the body of evidence for shared underlying pathophysiological mechanisms in systemic inflammatory states.

Lines Of Evidence

Maternal Diabetes is one of the most common metabolic disorders resulting an increased risk of abnormalities in the developing fetus and offspring. It is estimated that the prevalence of diabetes during pregnancy among women in developing countries is approximately 4.5 percent and this range varies between 1 to 14 percent in different societies. According to earlier studies, diabetes during pregnancy is associated with an increased risk of maternal and child mortality and morbidity as well as major congenital anomalies including central nervous system (CNS) in their offspring. Multiple lines of evidence have suggested that infants of diabetic women are at risk of having neurodevelopmental sequelae. Previous studies reveal that the offspring of diabetic mothers exhibit disturbances in behavioral and intellectual functioning. In the examination of cognitive functioning, a poorer performance was observed in the children born to diabetic mothers when compared with the children of non-diabetic mothers. Therefore, it is important to study the possible effects of maternal diabetes on the hippocampus of these infants.

The authors summarize the harmful and understudied aspects of the overuse of benzodiazepines. Increased and longer-term use of benzodiazepines has been observed to lead to side effects such as sedation, cognitive issues, abuse, and dependence, as well as many other unanticipated side effects that do not fit their known mechanism of action in the central nervous system. Data also shows a correlation between concomitant use of benzodiazepines and opioids and increased risk of death from overdose. The authors advocate for stricter guidelines for prescribing benzodiazepines, as well as close clinical monitor and shorter-term treatment plans.
