Sixty-five (66%) patients were implanted for primary prevention. Dual-chamber ICDs with or without CRT were 21 and 65%, respectively. Obstructive HCM was present in 47% pacemaker patients and 25% ICD patients with available pre-implant echo. Conclusions This retrospective registry-based study provides a picture of CIED first implants in HCM patients in a Swedish tertiary university hospital. ICDs were the most commonly implanted devices, covering 59% of CIED implants. https://www.selleckchem.com/products/nf-kb-activator-1.html HCM patients receiving a pacemaker or an ICD had different epidemiological and clinical profiles.Introduction Migraine is a chronic neurovascular disorder characterized by recurrent headache attacks associated with neurological and autonomic symptoms. The pathophysiological mechanisms of the disease are extremely complex, involving hypothalamic and trigeminovascular activation, cortical spreading depression, release of pro-inflammatory peptides, peripheral and central sensitization. The underlying cellular and molecular mechanisms have been scarcely investigated. Recently, genetic studies have suggested that different metabolic pathways could be involved in the pathogenesis of migraine.Areas covered This review focuses on cellular and molecular mechanisms involved in migraine, suggesting a role for circadian clocks, ion channels, synaptic plasticity, vascular factors, ion metal homeostasis, and impaired glucose metabolism in the pathogenesis of the disease. Accordingly, the article proposes new therapeutic targets that may be of particular relevance for disease prevention.Expert opinion Several complex molecular mechanisms are involved in setting the genetic threshold for migraine and the pathogenesis of headache attacks. Most promising new therapeutic targets are the modulation of hypothalamic activity and ion channels involved in pain transmission. Further studies in animals and humans are necessary to enhance the elucidation of the molecular mechanisms of migraine and open new avenues for disease prevention.Although offense-supportive cognitions are related to the maintenance of contact sexual offending behavior, it is unknown whether this finding also applies to online sexual offending behavior. A few studies have examined the cognitions of men convicted for using child sexual exploitation material, but findings remain limited due to important methodological limitations. Furthermore, fewer studies have investigated the cognitions of men who use the internet to solicit sexual activities with children. The objective of this study was to examine the nature of the cognitions that support online sexual offending against children. The content of police interviews was analyzed using a thematic analysis to identify the cognitive themes present in the offense-related views expressed by 20 men who consumed child sexual exploitation material, 15 who sexually solicited children, and 18 who committed both types of online offenses. Results revealed eight cognitive themes that reflected four underlying themes related to interpersonal relationships, the sexualisation of children, perceptions of the self, and perceptions of the virtual environment. Findings indicate that while the cognitive themes of the three groups are similar, their specific content varies according to the types of offenses. Implications for future research are discussed.The spread of tobacco smoking has increased over time at the global and national levels. One of the widely spread tobacco products is waterpipe. Recent studies showed that waterpipe tobacco smoke contains toxic substances, including carbon monoxide and nicotine. Some of them are genotoxic carcinogen, such as formaldehyde. This study aims to provide comprehensive insight into the types and depth of the scientific literature on waterpipe tobacco smoke chemical content, its genotoxic effects, and waterpipe device microbial contamination. We conducted a systematic comprehensive review of articles published between 1986 and December 2018. Primary research articles focusing on the content of waterpipe smoke, including chemical, genotoxic, and microbial contaminants, were eligible for inclusion. Of the 1,286 studies generated, 22 studies were included. Twenty-three chemical families were extracted from waterpipe smoke. Aldehydes were the most identified chemical family in 6 studies, and next is polycyclic hydrocarbons, found in 5 studies. About 206 chemical compounds were identified. Flavobacterium, Pseudomonas, coagulase-negative Staphylococci, and Streptococcus were the most abundant pathogen contaminants. Waterpipe smoke had elevated levels of many DNA damage markers (8-hydroxy-2'-deoxyguanosine and cytochrome P450 1A1) and inhibited levels of many DNA repair genes (OGG1 and XRCC1) in waterpipe smokers. Waterpipe smoke is associated with the genotoxic effect, which elevates the levels of many DNA damage markers and inhibits the levels of many DNA repair genes. In addition, waterpipe smoking can expose smokers to a range of pathogenic bacteria.Hemophagocytic lymphohistiocytosis (HLH) is a rare, aggressive, and, if not treated, fatal disorder that is characterized by excessive immune system activation. This disorder can be precipitated by different triggers including malignancies, infections, and autoimmune disorders. Diagnosis is made by fulfilling criteria that was last updated in 2004, and treatment frequently includes management of the underlying trigger but can also include chemotherapy. In this article, we report a case of HLH in a 27-year-old male, who had been diagnosed with advanced untreated HIV, who presented to the hospital with fever and generalized fatigue with no obvious etiology. Infectious workup revealed cytomegalovirus viremia, and the patient met HLH criteria with impressive hyperferritinemia of 15 432 ng/mL. The patient was started on treatment for cytomegalovirus infection that led to resolution of HLH. Our report highlights the importance of early detection of HLH in special populations, and that treating the presumptive trigger can lead to resolution of HLH.Pulmonary complications from cocaine use can range from bronchospasm to vasospasm leading to pulmonary infarction. Profound vasospasm may also lead to perfusion defects presenting as pulmonary embolism on ventilation-perfusion scan. A 65-year-old patient with a past medical history of substance abuse and chronic kidney disease presents to the emergency department with sudden-onset chest pain and shortness of breath. Ventilation-perfusion scan revealed filling defect most notably in the lingual lobe. He was later discharged on warfarin for the management of pulmonary embolism. The patient presented to the emergency department 2 weeks later with similar complaints; the international normalized ratio was subtherapeutic, and urine drug screen was positive for cocaine. Repeat ventilation-perfusion scan revealed no filling defects. Follow-up bilateral venous Doppler of lower extremities and D-dimer were within normal limits.
