Objective: To explore the clinical features, the serotype distribution and drug resistance of the isolates in patient with invasive pneumococcal disease (IPD). Methods: By retrieving the laboratory information system in 18 children's hospitals from 2012 to 2017, the children with IPD were enrolled. Streptococcus pneumoniae (Spn) must be isolated from the sterile sites (blood, cerebrospinal fluid, hydrothorax and joint effusion etc.). The clinical characteristics, serotype, drug resistance, treatment and prognosis were reviewed and analyzed...

A single LC-MS/MS assay is developed and validated for simultaneous determination of metformin and dapagliflozin in human plasma using ion-pair solid phase extraction. Chromatographic separation of the analytes and their internal standards was carried out on a reversed-phase ACE 5CN (150 × 4.6 mm, 5 μm) column using acetonitrile-15 mM ammonium acetate, pH 4.5 (70:30, v/v) as the mobile phase. To achieve higher sensitivity and selectivity for the analytes, mass spectrometric analysis was performed using polarity switching approach...

Pain management laboratories analyze biological fluids (urine, saliva or blood) from patients treated for chronic pain to ensure compliance and to detect undisclosed drug use. The quantitation of multi-panel drugs in urine and tissues utilizes β-glucuronidase to cleave the glucuronic acid and liberate the parent drug for mass spectrometry analysis. This work focuses on the comparison of three different, purified and commercially available β-glucuronidases across 83 patient urine samples. One enzyme is genetically modified, expressed in bacteria and the other two enzymes are purified from abalone...

Background: During the course of dementia, most people develop some type of neuropsychiatric symptoms (NPS), which result in lower quality of life, high caregiver burden, psychotropic drug use and a major risk of institutionalization. Studies on NPS in people with dementia have been mainly conducted in clinical centres or psychiatric services. Objectives: To investigate the course of NPS in people with dementia in primary care. Methods: Analysis of (cumulative) prevalence and incidence, persistence and resolution based on data collected during an assessment at home of a prospective naturalistic cohort study in primary care in a sample of 117 people with dementia and their informal caregivers...

OBJECTIVES: to validate the vulnerability markers of dysfunctions in the socioemotional development of infants. METHODS: study with a sequential exploratory mixed-method design. The vulnerability markers elaborated in the qualitative phase were analyzed by experts in the quantitative phase using the Delphi technique with a minimum consensus of 70%. Seventeen judges answered the questionnaire in the first round of analysis and 11 answered in the second round. RESULTS: in the first round, two markers did not reach minimum consensus: the presence of instability in family relationships (66%) and delinquency and/or drug abuse by parents/caregivers (65%)...

Bleaching gel containing hydrogen peroxide (H2O2) cause damages in pulp tissue. This study investigated the action of a topical anti-inflammatory, the Otosporin®, in rats' bleached teeth with the null hypothesis of which the Otosporin® is no able to minimize the pulp inflammation that bleaching gel generates. The rat's molars were divided into groups: BLE: bleached (35% H2O2 concentration /single application of 30 min); BLE-O: bleached followed by Otosporin® (10 min); and control: placebo gel. In the second day after dental bleaching, the rats were killed, and the jaws were processed for hematoxylin-eosin and immunohistochemistry analysis for tumor necrosis factor alpha (TNF-α), interleukin (IL)-6 and IL-17...

Health self-assessment (HSA) is a widely studied indicator among adults and the elderly, but not often explored in adolescents. This study aimed to estimate the prevalence of poor self-rated health in Brazilian schoolchildren and associated factors. Data from the 2015 National Adolescent School-based Health Survey (PeNSE) were analyzed; prevalences and their 95% confidence intervals (95%CI) were estimated for poor self-rated health and associated factors. Multiple logistic regression analysis was performed...

This study aimed to evaluate the effect of two methods of local application of alendronate and parathyroid hormone (PTH) on bone repair and the systemic implications. A critically sized defect (5 mm) was created in the cranial region of twenty-five male Wistar rats, and the bone removed was particulated, and grafted back to the defect with different treatments. The animals were randomly divided into five groups: A1- bone graft immersion in alendronate solution (3 mg/kg) for 5 minutes; P1- bone graft immersion in PTH solution (20 µg); A2- weekly local applications of alendronate 1 mg/kg; P2- weekly local applications of PTH (20 µg); C- no drugs were used...

Illicit drug use is related to individual characteristics; however, social and family environments seem to be associated with this consumption. The aim of this study was to analyze the association of the relationships between parents or guardians and Brazilian adolescents that use illicit drugs. This is a cross-sectional study with data from the Brazilian National Survey of School Health (PeNSE, 2015), in which the target population was school children from the ninth grade (eighth year). A total of 102,072 students were included in the current research, being 52,782 females and 49,290 males...

Identification of hotspot drug-receptor interactions through in-silico prediction methods (Pharmacophore mapping, virtual screening, 3DQSAR, etc), is considered as a key approach in drug designing and development process. In the current design study, advanced in-silico based computational techniques were used for the identification of lead-like molecules against the targeted receptor β-glucuronidase. The binding pattern of a potent inhibitor in the ligand-receptor X-ray co-crystallize complex was used to identify and extract the structure-base Pharmacophore features...

SummaryMany novel therapeutic options for depression exist that are either not mentioned in clinical guidelines or recommended only for use in highly specialist services. The challenge faced by clinicians is when it might be appropriate to consider such 'non-standard' interventions. This analysis proposes a framework to aid this decision.Declaration of interestIn the past 3 years R.H.M.W. has received support for research, expenses to attend conferences and fees for lecturing and consultancy work (including attending advisory boards) from various pharmaceutical companies including Astra Zeneca, Cyberonics, Eli Lilly, Janssen, LivaNova, Lundbeck, MyTomorrows, Otsuka, Pfizer, Roche, Servier, SPIMACO and Sunovion...
