Infecciones de transmisión sexual en hombres internos en prisión: riesgo de desarrollo de nuevas infecciones

ObjectiveTo measure incidence and main risk factors related to sexually transmitted infections (STIs) in Daroca Prison (Zaragoza, Spain).MethodA retrospective cohort study (2005-2013) to measure the incidence of STI and a cross-sectional study to measure risk factors.ResultsOf the 203 inmates, 79 developed an STI, 37 had a previous STI, 55.2% lacked knowledge on STI prevention, and 28.9% showed behaviours unfavourable for STI prevention. The incidence rate was 6.5 STIs per 1,000 inmates-year. The most frequent STIs were hepatitis B (39.7%), Ureaplasma urealyticum (19.1%), herpes simplex (16.2%) and HIV (8.8%). The risk (hazard ratio, HR) of acquiring a new STI was significantly higher in inmates with a history of previous STI (HR = 2.61; 95%CI: 1.01 to 6.69), and was at the limit of significance for non-preventive behaviour (HR = 2.10; 95%CI: 0.98 to 4.53), but not in knowledge related to STIs (HR = 1.33; 95%CI: 0.58 to 3.07).ConclusionThe most important risk factors in prison are behaviours related to STIs and previous history of STIs. Other factors are being a repeat offender, injecting drug use, or being in a methadone programme. Health personnel and peer education can facilitate prevention and control.     

Principles of pressure transducer function and sources of error in clinical use

The invasive measurement of physiological pressures is a common requirement in anaesthesia and intensive care medicine. From arterial blood pressure to intracranial pressure, these calculated variables give a swift graphical and numerical representation of a patient's current physiological status. This allows us to respond rapidly to conditions outside our preferred parameters and to carefully titrate treatment to target effects. These systems are, however, not infallible. An understanding of the principles of their function will promote appropriate use and an ability to recognize and react to sources of error. This article aims to furnish the reader with this level of understanding in order to inform their academic and clinical practice.

Narcolepsy in Slovakia – Epidemiology,clinical and polysomnographic features,comorbid diagnoses: a case-control study

ObjectiveAn increase in the incidence of narcolepsy after the pandemic influenza with the H1N1 vaccination in 2009 resulted in an interest in narcolepsy epidemiology. The aim of the study was to examine the incidence and prevalence rates of narcolepsy and to describe the associated characteristics in Slovakia.MethodsEpidemiology data were calculated for each year from 2000 to 2017 based on records found in specialized centres. In sum, 61 narcoleptic patients were diagnosed, of which 51 (84%) had narcolepsy type 1 (NT1). Clinical data and results of polysomnography (PSG), Human Leukocyte Antigen (HLA)-typing, hypocretin (HCRT)-1 levels and body mass index (BMI) were summarised and evaluated for NT1 and narcolepsy type2 (NT2). Later, 244 sex and age matched controls were chosen to evaluate the comorbid diagnoses.ResultsThe prevalence of narcolepsy in 2017 in Slovakia was 10.47 (CI 95% 8.26–14) cases/million inhabitants, and the mean incidence rate (2000–2017) was 0.57 (CI 95% 0.4–0.74) cases/million inhabitants.Narcoleptic patients were comorbid with arterial hypertension (17%), ischemic heart disease (8%), dyslipidaemia (18%), diabetes mellitus type 2 (10%), cardiac arrhythmia/atrial fibrillation (5%), autoimmune disorders (20%), allergy (11%), malignancy (3%), headache (15%) and mental disorders (20%). Patients with narcolepsy showed double the excess prevalence in mental disorders (OR 2.15, p < 0.05), and dyslipidaemia (OR 2.22, p < 0.05). The presence of autoimmune disorders and allergy showed a mild increase in the narcolepsy group (OR 1.46, resp. 1.63). Hashimoto thyroiditis (HT) was the most frequent autoimmune disorder.ConclusionsNarcolepsy is a rare disorder in Slovakia. From the phenotype, genetic characteristics and comorbidities the disorder does not vary from other European countries.     

Application of a photoelectric magnifier to nasal injury in preterm infants receiving non-invasive ventilation: A prospective observational study

PurposeThis study was to explore a photoelectric magnifier assessing nasal injury in preterm infants receiving non-invasive ventilation (NIV) treatment, and to describe the occurrence status and risk factors of nasal injuries.DesignA prospective observational study.Subjectsand setting: Preterm infants admitted from the Second Affiliated Hospital of Wenzhou Medical University between October 2018 and October 2019.MethodsA continuously convenient sample of 127 preterm infants was included. When the infants were receiving NIV treatment, nursing staff checked nasal skin and mucosa daily with a photoelectric magnifier to confirm whether nasal injuries occurred. Meanwhile, a self-designed questionnaire was used to collect data. The Chi-square test, t-test, univariate and multiple logistic regression model were applied.ResultsA total of 127 preterm infants received 175 times NIV therapy, showing that the incidence of nasal injuries (infants number) was 27.6% (35/127) and the incidence of nasal injuries (ventilation cases) was 21.1% (37/175). Of the 37 cases of nasal injuries, 27 cases were I stage, while Ⅱ stage, Ⅲ stage and mucosa injuries appeared 2 cases, 2 cases and 6 cases. In the multivariate logistic analysis, nasal mask interface and NIV treatment more than seven days were independent risk factors affecting the occurrence of nasal injuries.ConclusionsThe premature infants who received nasal NIV treatment were susceptible to nasal injuries, and clinical nurse capable of identifying risk factors and inintervening should be strengthened to prevent the occurrence and progression.     

Sensory evoked potentials in patients with Rett syndrome through the lens of animal studies: Systematic review

ObjectiveSystematically review the abnormalities in event related potential (ERP) recorded in Rett Syndrome (RTT) patients and animals in search of translational biomarkers of deficits related to the particular neurophysiological processes of known genetic origin (MECP2 mutations).MethodsPubmed, ISI Web of Knowledge and BIORXIV were searched for the relevant articles according to PRISMA standards.ResultsERP components are generally delayed across all sensory modalities both in RTT patients and its animal model, while findings on ERPs amplitude strongly depend on stimulus properties and presentation rate. Studies on RTT animal models uncovered the abnormalities in the excitatory and inhibitory transmission as critical mechanisms underlying the ERPs changes, but showed that even similar ERP alterations in auditory and visual domains have a diverse neural basis. A range of novel approaches has been developed in animal studies bringing along the meaningful neurophysiological interpretation of ERP measures in RTT patients.ConclusionsWhile there is a clear evidence for sensory ERPs abnormalities in RTT, to further advance the field there is a need in a large-scale ERP studies with the functionally-relevant experimental paradigms.SignificanceThe review provides insights into domain-specific neural basis of the ERP abnormalities and promotes clinical application of the ERP measures as the non-invasive functional biomarkers of RTT pathophysiology.     

Injuries in England and Wales elite men’s domestic cricket: A nine season review from 2010 to 2018

ObjectivesThis study primarily aimed to explore injury incidence rates in the three main domestic competition formats in England and Wales (First-Class, One-Day and Twenty20 [T20]). For the first time, the study also describes the epidemiology of elite men’s domestic cricket injuries across nine seasons (2010–2018 inclusive).DesignProspective cohort analysis.MethodsInjury incidence and prevalence from all injuries calculated according to the updated international consensus statement on injury surveillance in cricket, with statistical process control charts (SPC) used to detect trends in the data.ResultsThe average match injury incidence was 102 injuries/1000 days of play, with highest incidence in One-Day (254 injuries/1000 days of play), followed by T20 (136 injuries/1000 days of play) and First-Class Cricket (68 injuries/1000 days of play). Most match injuries were sustained during bowling (41.6 injuries/1000 days of play), followed by fielding (26.8 injuries/1000 days of play) and batting (22.3 injuries/1000 days of play). The thigh was the body area most commonly injured (7.4 injuries/100 players per season), with lumbar spine injuries the most prevalent (1.3% of players unavailable on any given day during the season). On average, 7.5% of players were unavailable on any given day during the domestic season when all injuries were considered (match and training). The SPC charts showed relatively consistent match injury incidence for all competitions, reproduced across all nine seasons.ConclusionThese findings provide a robust empirical base for the extent of the injury problem in domestic cricket played in England and Wales, with similar injury profiles across the three formats.
