Macimorelin is an orally active ghrelin receptor agonist indicated for the diagnosis of adult growth hormone (GH) deficiency in the United States. This phase 1 study evaluated the safety, tolerability, pharmacokinetics, and pharmacodynamics of single ascending doses of macimorelin (including a supratherapeutic dose to be used in a thorough QT trial) in healthy adults.

Prescription of opioids to treat pediatric migraine is explicitly discouraged by treatment guidelines but persists in some clinical settings. We sought to describe rates of opioid administration in pediatric migraine hospitalizations.

Since Dec 2019, a cluster of pneumonia outbreak in Wuhan, Hubei province, China, and soon spread to all province of China. The pathogen was proved to be a novel betacoronavirus called 2019 novel coronavirus (officially named by the World Health Organization as COVID-19). The typical clinical manifestations were fever, cough, dyspnea, and myalgia or fatigue. Less common symptoms included headache, diarrhea, nausea and vomiting. However diarrhea as the first symptom is rarely reported. Here we reported a case of 2019 novel coronavirus-infected patient (NCIP) with diarrhea as the initial symptom. Image of CT scan and laboratory examination and careful collected as well as detection of viral RNA in pharynx. The case demonstrate that gastrointestinal symptoms ware not rare in NCIP, and diarrhea could be the initial symptom.

The pathophysiology of septic acute kidney injury is inadequately understood. Recently, subphenotypes for sepsis and AKI have been derived. The objective of this study was to assess whether a combination of comorbidities, baseline clinical data, and biomarkers could classify meaningful subphenotypes in septic AKI with different outcomes.

To assess the short-term safety and efficacy of gallbladder cryoablation in high-risk patients.

: Migraine is a complex episodic disease manifested by dysfunction of the sympathetic nervous system along with numerous neuropsychiatric symptoms. The aim of this study was to identify the dissociative symptoms with neurobiological similarities in episodic and chronic migraine patients and to evaluate their correlation with migraine frequency and severity of attacks.: The study included 61 episodic, 45 chronic migraine patients diagnosed using the criteria of the International Headache Society and 54 healthy control subjects. Dissociative Experiences Scale, Beck Anxiety Scale and Beck Depression Inventory were filled with the interviews. Demographic, clinical and headache characteristics of the patients were recorded according to migraine types. Results were analyzed by Kruskal-Wallis method and Spearman's correlation tests.: Dissociative symptoms were more common in the patients with chronic migraine, and there was a statistically significant difference between the chronic migraine group and the episodic migraine and control groups (p = 0.001, p < 0.001). Dissociative experiences were correlated with depression and anxiety findings, and in both groups, there was a significant correlation between clinical characteristics of migraine and osmophobia in the controlled partial correlation analysis (p < 0.05).: This study revealed that dissociative symptoms are more common especially in patients with chronic migraine and there is a significant association with osmophobia in both migraine groups. According to these data, we think that dissociative symptoms in chronic migraine patients will be questioned and osmophobia may be a guide in this regard.

Painful knee after arthroplasty concerns up to 21% of patients at six months. We aimed to evaluate: the application of a decision tree to explain painful knee after total knee arthroplasty (TKA), the rate of unexplained pain after complete algorithmic screening. The aim of the study was to evaluate the causes of painful TKA. Our hypothesis was that it is possible to find the cause of the pain in more than 90% of cases.

A positive feedback loop between inflammatory cytokines and alpha-adrenoceptors (α-AR) (a target of the sympathetic nervous system neurotransmitter norepinephrine) influences inflammatory responses in immune cells. This cross-talk between the sympathetic nervous system and immune system may play a role in promoting chronic inflammation. Emerging evidence shows that α-AR interact with inflammatory cytokines in keratinocytes, and this epidermal adrenergic signalling may contribute to skin inflammatory responses following injury, disease or stress. In this study, utilizing an in vitro approach, we hypothesized that α-AR interact in a positive feedback loop with inflammatory mediators in keratinocytes. The pro-inflammatory cytokine tumor necrosis factor α (TNFα) was used to induce an inflammatory state in cultured keratinocytes. TNFα increased interleukin (IL)-1β, IL-6, IL-8 and nerve growth factor (NGF) production and gene expression levels of α-AR subtype B (α-AR). Additional stimulation of α-AR further increased IL-6 levels, while maintaining high levels of IL-8 and decreasing levels of IL-1β and NGF. Our results suggest that reciprocal influences between α-ARs and inflammatory cytokines may play a role in normal inflammatory responses. However, if unchecked, this cycle could contribute to pathology (e.g. chronic inflammatory diseases, chronic pain conditions, and stress-induced cancer progression).
