The present study examined the validity of the coronaphobia phenomenon with healthcare professionals using a psychometric approach. Using SurveyMonkey, an adapted version of the Coronavirus Anxiety Scale-Healthcare version (CAS-HC) was administered to 231 adult healthcare professionals in Mexico. Confirmatory factor analysis demonstrated that dysfunctional coronavirus anxiety symptoms cohered into a reliable, single factor structure of coronaphobia. A receiver operating characteristic curve analysis indicated that the classification features of the CAS-HC were strong, but supported a less stringent cut-score for this population. Construct validity was supported by the positive correlations between the CAS-HC and measures of depression and generalized anxiety, while known groups validity was found with high CAS-HC scores exhibited by those working in emergency rooms, triage, and intensive care units. The findings collectively support the coronaphobia construct with healthcare professionals, and the finding that over one third of the participants in the study scored in the clinical range on this measure points to the critical importance of assessing and alleviating this form of distress in this vulnerable but indispensable workforce.
Dermatitis artefacta is a factitious disorder in which there is deliberate conscious production of skin lesions. There are only a few reports that evaluate instances of dermatitis artefacta in the pediatric population. The aim of this retrospective study was to assess the characteristics of patients with this disorder who were seen at the National Institute of Pediatrics in Mexico City. The records of all patients diagnosed with dermatitis artefacta from January 1980 to December 1999 were analyzed. There were 29 patients (25 females, 4 males). The upper limbs and the face were the most commonly involved areas. Superficial erosions were the most frequent initial event, and residual lesions consisted of scars and crusts. Time taken to diagnosis was on average 10 months. Half of the patients were lost to follow-up. No correlation was found between the length of time from the disease onset to diagnosis, the type of lesions, and the clinical outcome. Twelve patients had an associated systemic disorder. The possible association with chronic disease has not been sufficiently stressed and demonstrates the importance of providing psychological support for these patients. Psychiatric diagnoses were anxiety, depression, and personality disorder. No correlation was found between the psychiatric diagnosis and the outcome of dermatitis artefacta. A young age at presentation, which has been considered important as a favorable prognostic sign, could not be demonstrated in our patients.
BackgroundIn recent years, medical practice has followed two different paradigms: evidence-based medicine (EBM) and values-based medicine (VBM). There is an urgent need to promote medical education that strengthens the relationship between these two paradigms. This work is designed to establish the foundations for a continuing medical education (CME) program aimed at encouraging the dialogue between EBM and VBM by determining the values relevant to everyday medical activities.MethodsA quasi-experimental, observational, comparative, prospective and qualitative study was conducted by analyzing through a concurrent triangulation strategy the correlation between healthcare personnel-patient relationship, healthcare personnel's life history, and ethical judgments regarding dilemmas that arise in daily clinical practice.In 2009, healthcare personnel working in Mexico were invited to participate in a free, online clinical ethics course. Each participant responded to a set of online survey instruments before and after the CME program. Face-to-face semi-structured interviews were conducted with healthcare personnel, focusing on their views and representations of clinical practice.ResultsThe healthcare personnel's core values were honesty and respect. There were significant differences in the clinical practice axiology before and after the course (P <0.001); notably, autonomy climbed from the 10th (order mean (OM) = 8.00) to the 3rd position (OM = 5.86). In ethical discernment, the CME program had an impact on autonomy (P ≤0.0001). Utilitarian autonomy was reinforced in the participants (P ≤0.0001). Regarding work values, significant differences due to the CME intervention were found in openness to change (OC) (P <0.000), self-transcendence (ST) (P <0.001), and self-enhancement (SE) (P <0.019). Predominant values in life history, ethical discernment and healthcare personnel-patient relation were beneficence, respect and compassion, respectively.ConclusionsThe healthcare personnel participating in a CME intervention in clinical ethics improved high-order values: Openness to change (OC) and Self Transcendence (ST), which are essential to fulfilling the healing ends of medicine. The CME intervention strengthened the role of educators and advisors with respect to healthcare personnel. The ethical values developed by healthcare professionals arise from their life history and their professional formation.
Human milk is recommended as the only alimentary source for the first six months of life. Additionally there is a medical and social need for safe and effective alternative forms of nutrition for infants who cannot be fed with breast milk. Recently the safety and efficacy of some ingredients in infant formulae, such as nucleotides have been discussed. This systematic review analyzed the available evidence to establish the efficacy, safety and dose-response effect of ribonucleotide-supplemented infant formulae (RSIFs). Randomised controlled clinical trials (RCTs) comparing RSIFs to formulae without nucleotides or breast milk were considered in this review. Outcome measures were: antibody titres to common paediatric vaccinations, total lymphocytes, lymphocyte subclasses and NK-cells, episodes of diarrhoea and acute respiratory infection. Publication quality was determined using Jadad and CONSORT guidelines. Results were combined using a random effects model and reported through standardised mean differences (WMD) or risk ratio (RR). Systematic review and meta-analysis showed that RSIFs were associated with a better antibody response to immunisation with Haemopillus influenzae vaccine [SMD 1·74 (99 %CI 1·43 -2·05),, and fewer episodes of diarrhoea [RR 0·67 (0·58 -0·76), P ¼ 0·02]. We did not find a major risk of upper respiratory infections [RR 1·11 (0·90 -1·36), P ¼ 0·50]. Available evidence suggests a positive benefit of RSFIs on infant health without any risk. These benefits begin with nucleotide addition of 1·9 mg/418·4 kJ and are maintained or increased with 10·78 mg/418·4 kJ.
Transcranial magnetic stimulation is a non-invasive method used to assess motor function in humans; however, some reports suggest it may cause internal ear damage (cochlear). Eighteen patients with normal auditory function (ages 2 months to 16 years, mean 6.8 years), two medical doctors and two technicians who performed the studies were tested with brain stem auditory evoked potentials, otoacoustic emissions, acoustic reflex and a pure tone audiometric and logoaudiometric test when possible, before and after transcranial magnetic stimulation for central motor conduction studies in different neurological conditions. All the tests were repeated two weeks and two months later. Patients had no auditory protection nor history of seizures. Motor evoked potentials and silent periods were recorded from the right abductor pollicis brevis and the first dorsal interosseous muscles at rest and during weak voluntary contraction when possible. A mean of 48 transcranial magnetic stimulations with 50%-75% Tesla intensity were used. Natural logarithmic transformation of latency and amplitude data had a normal distribution. There were no significant differences in auditory function testing.
PARA CITAR ESTE ARTÍCULO / TO REFERENCE THIS ARTICLE / PARA CITAR ESTE ARTIGOEste artículo identifica, a partir de evidencia científica, la sobrevida en pacientes con sedación paliativa en comparación con aquellos que no la recibieron. Se realizó búsqueda de revisiones sistemáticas de 2000 a 2016, se analizaron metodológicamente y se compararon los resultados. Por razones metodológicas no se pudo realizar meta-análisis. Se concluye que la sedación paliativa terminal no acorta la vida de los pacientes. Se reformula la aplicación del principio de doble efecto relacionado con el posible acortamiento de la vida; el mal no deseado es la pérdida de la conciencia. PALAbRAS CLAve: pacientes terminales; sedación paliativa; síntomas refractarios; eutanasia; calidad de vida (Fuente: DeCS).
