Pseudomonas aeruginosa is a major cause of chronic lung infections in cystic fibrosis (CF) patients. The ability of the bacterium to form biofilms and the presence of a thick and stagnant mucus in the airways of CF patients largely contribute to antibiotic therapy failure and demand for new antimicrobial agents able to act in the CF environment. The present study investigated the anti-P. aeruginosa activity of lin-SB056-1, a recently described semi-synthetic antimicrobial peptide, used alone and in combination with the cation chelator ethylenediaminetetraacetic acid (EDTA)...

Stress has adverse effects on social behavior that is mediated by dopamine circuits in the midbrain. The purpose of this research is to examine the effect of chronic stress and dopamine signals on social behavior in zebrafish (Danio rerio). Chronic stress was induced chemically with low dosage of ethanol (0.25% for 5 days), and psychosocially with isolation (3-5 days) or overcrowding (5 days). Dopamine activity was decreased by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) exposure. Social behavior was observed by introducing one treated zebrafish to a group of four control zebrafish and measuring the nearest neighbor distance (NND)...

Acute exacerbation of chronic obstructive pulmonary disease (COPD) is a clinical diagnosis that is based on changes in dyspnea, cough, and/or sputum production in a COPD patient; however, patients presenting with an acute exacerbation may be undiagnosed or have a variety of comorbid conditions that can complicate diagnosis. This issue presents strategies and algorithms for the early use of evidence-based interventions, including appropriate use of antibiotics, bronchodilators, and corticosteroids, along with noninvasive ventilation with capnography, to minimize morbidity and mortality associated with this disease...

The BDNF Val66Met polymorphism has been associated with sensitivity to stress and affective disorders. We therefore sought to model the inter-causality of these relationships under controlled laboratory conditions. We subjected humanized BDNF Val66Met (hBDNF(Val66Met)) transgenic mice to a history of stress, modeled by chronic late-adolescent corticosterone (CORT) exposure, before evaluating affective-related behavior using the forced-swim test (FST) in adulthood. While hBDNF(Met/Met) mice had a depression-like phenotype in the FST irrespective of CORT, hBDNF(Val/Val) wildtype mice had a resilient phenotype but developed an equally robust depressive-like phenotype following CORT...

Background: Mitochondrial disorders can present as kidney disease in children and be difficult to diagnose. Measurement of mitochondrial function in kidney tissue may help diagnosis. This study was to assess the feasibility of obtaining renal samples and analysing them for respiratory chain enzyme activity. Methods: The subjects were children undergoing a routine diagnostic renal biopsy, in whom a clinical condition of renal inflammation, scarring and primary metabolic disorder was unlikely. A fresh sample of kidney was snap frozen and later assayed for the activities of respiratory chain enzyme complexes I, II/III, and IV using spectrophotometric enzyme assay, and expressed as a ratio of citrate synthase activity...

BACKGROUND: Pulmonary conditions such as asthma and chronic obstructive pulmonary disease (COPD) are common conditions that warrant special consideration in the perioperative period. When these patients undergo surgical interventions, they have risk of complications such as bronchospasm, hypoxia, and even postoperative respiratory failure that warrants unplanned intensive care unit admission. Thus, clinicians must be familiar with pulmonary medication regimens that are critical for maintaining stable homeostasis of these chronic conditions...

Diabetes is one of the most prevalent chronic health conditions in the world; with a range of diabetes-related mobile applications available to the public to aid in glycaemic control and self-management. Statistically, adherence to medication is extremely low in adolescents with Type 1 Diabetes Mellitus (T1DM), therefore, this paper focuses on the research and design of an interactive and educational concept mobile application aimed at early to mid-adolescents to aid in their understanding of T1DM. As visual elements are an essential part of the design, this research outlines how visual components were designed specifically for adolescents with T1DM...

Accurate noninvasive diagnostic tests for endometriosis are still missing. This study evaluated the predictive value of the neuropeptide urocortin 1 (Ucn1) to detect pelvic endometriosis in symptomatic women. We enrolled prospectively 97 consecutive women submitted to gynecologic laparoscopy for chronic or acute pelvic pain, infertility or adnexal mass. Preoperative blood samples were assayed for Ucn1 using enzyme immunoassay. Patients with endometriosis had higher plasma Ucn1 levels compared to patients with no lesions (median 59 vs...

A challenge in the Choosing Wisely campaign is to identify low-value clinical actions supported by high-quality evidence. We applied a method based on crowdsourcing the Daily POEM (patient-oriented evidence that matters) to identify low-value clinical actions from research studies consistent with the principles of Choosing Wisely. In 2016, we analyzed an average of 1,382 questionnaires on 265 unique POEMs delivered to physician members of the Canadian Medical Association. From these questionnaires, we identified the POEMs ranking highest on one questionnaire item directly linked to reducing overdiagnosis or overtreatment...

OBJECTIVES: Dental diseases are the most common chronic diseases worldwide. Healthy teeth are vital for quality of life, particularly diet and nutrition. However, little information exists to inform health policymakers about potentially long-lasting influences of early-life conditions. The purpose of this study was to investigate the relation between early-life socioeconomic conditions and number of natural teeth at age 50 and above. METHODS: Analyses were conducted on cross-sectional data from the Survey of Health, Ageing and Retirement in Europe (SHARE wave 5), which includes information on 41 560 respondents aged 50 years or older from 14 European countries and Israel...

BACKGROUND: With the continuous and enormous spread of mobile technologies, mHealth has evolved as a new subfield of eHealth. While eHealth is broadly focused on information and communication technologies, mHealth seeks to explore more into mobile devices and wireless communication. Since mobile phone penetration has exceeded other infrastructure in low and middle-income countries (LMICs), mHealth is seen as a promising component to provide pervasive and patient-centered care. OBJECTIVES: The aim of our research work for this paper is to examine the mHealth literature to identify application areas, target diseases, and mHealth service and technology types that are most appropriate for LMICs...

Chronic urticaria (CU) is a group of common and debilitating conditions containing both chronic spontaneous urticaria (CSU) and chronic inducible urticarias (CIndU) including cold urticaria (ColdU) [1]. While antihistamines and omalizumab are effective treatments for both CSU and ColdU [2], many patients show insufficient response to either or both of these treatments [3], and additional and better therapies are needed [4].

Elevated levels of fibroblast growth factor 23 (FGF23), a bone-derived phosphaturic hormone, are associated with a number of pathologic conditions including chronic kidney disease, cardiac hypertrophy, and congestive heart failure. Currently, there are no specific treatments available to lower plasma FGF23 levels. We have recently reported that genetic plasminogen activator inhibitor-1 (PAI-1) deficiency provided a significant reduction in circulating FGF23 levels while simultaneously prolonging the life span of Klotho-deficient mice...

AIM: To describe the surgical management of glaucoma in a patient with severe scleromalacia, and secondary angle closure. INTRODUCTION: The management of glaucoma with coexisting scleromalacia plus secondary angle closure is challenging as most commonly performed incisional glaucoma surgery as well as minimally invasive glaucoma surgery (MIGS), which targets the drainage angle are all contraindicated. CASE REPORT: Medically refractory glaucoma in a 60-year-old male with a 30-year history of granulomatosis with polyangiitis resulting in extensive severe scleromalacia, cicatricial lower lid retraction with significant conjunctival exposure, and widespread synechial angle closure from chronic anterior uveitis was managed with combined phacoemulsification cataract surgery, and endoscopic cyclophotocoagulation (ECP)...

Steroids are a group of anti-inflammatory drugs, commonly used to treat ocular and systemic conditions. Unmonitored use of steroids especially in eye drop formulations is common in situations when it is easily available over-the-counter, resulting in undesirable side effects. Among the ocular side effects, cataract and glaucoma are common. Steroid-induced ocular hypertension was reported in 1950, when long-term use of systemic steroid was shown to increase the intraocular pressure (IOP). Chronic administration of steroids in any form with raised IOP can cause optic neuropathy resulting in steroid-induced glaucoma...
