The aim of this study was to evaluate the effectiveness of an online nursing intervention called “dialogue circles” designed to reduce caregiver overload and enhance positive mental health (PMH) in family caregivers. We used a pre-post design. The sample consisted of 86 family caregivers of patients with complex chronic conditions, randomly assigned to the intervention group (n = 43) or the control group (n = 43). All participants completed the Zarit scale and the Positive Mental Health Questionnaire 15 days before starting the intervention and 30 days after its completion. Comparison of the post-test changes revealed statistically significant differences between the two groups in PMH and overload, with the intervention group showing greater positive changes in all dimensions of PMH after the intervention and lower scores on overload. In conclusion, the r...

The inclusion of self-care and positive mental health as part of a strategy to promote health offers an opportunity for a reorganization oriented towards community spaces and group interventions. This study undertook the assessment of an intervention designed to optimize the agency of and capacity for self-care and positive mental health by utilizing activities drawn from the Nursing Intervention Classification (NIC), specifically from Field 3 (Behavioral), and organized as a program called PIPsE. A quasi-experimental design was prepared with an intervention group (n = 22) and a control group (n = 22), in a primary care center in the Barcelona metropolitan area. The instruments used were two ad hoc questionnaires to collect sociodemographic and satisfaction information and two scales: the Appraisal of Self-care Agency Scale (ASA) and the Posi...

Se recomienda realizar un test diagnóstico a todos los pacientes con fiebre y cuadro gripal que requieran hospitalización. La muestra respiratoria (exudado nasal, faríngeo o muestra profunda en pacientes intubados) se debe obtener lo antes posible e iniciar inmediatamente tratamiento antiviral empírico. Los métodos moleculares basados en técnicas de amplificación de ácidos nucleicos (rt-PCR) son el «gold standard» para el diagnóstico de la gripe A/H1N1. Los métodos inmunocromatográficos son poco sensibles, por lo cual un resultado negativo no excluye la infección activa. El cultivo clásico en células es poco sensible y lento. La inmunofluorescencia directa tiene una sensibilidad del 90%, pero requiere una muestra de calidad. Los métodos indirectos de detección de anticuerpos tienen solo interés epidemiológico. Los pacientes afectados de gripe A/H1N1 pueden presentar leucopenia relativa, con elevación de LDH, CPK y PCR, aunque estas variables del laboratorio no se asocian de forma independiente con el pronóstico. Sin embargo, niveles plasmáticos de LDH >1.500 U/L y la presencia de plaquetopenia < 150 x 10 9 /L podrían definir una población de pacientes con riesgo de complicaciones graves. La administración del antiviral (oseltamivir) debe ser precoz (< 48 h desde el inicio de los síntomas), en una dosis de 75 mg cada 12 h, con una duración de al menos 7 días o hasta la mejoría clínica evidente. La administración precoz se asocia a mejor superviviencia en pacientes críticos. Nuevos antivirales, en especial aquellos formulados para administración intravenosa, podrían ser los de elección en futuras epidemias. Los pacientes con alta sospecha de gripe A/H1N1 deben continuar con tratamiento, independientemente de los resultados negativos de las pruebas iniciales, a menos que se pueda establecer un diagnóstico alternativo o los criterios clínicos sugieran una baja probabilidad de influenza En pacientes con neumonía por gripe A/H1N1 y dada la posibilidad de coinfección bacteriana, se recomienda cobertura antibiótica empírica (asociando un betalactámico con un macrólido) administrada lo antes posible. Los resultados de los cultivos y las variables clínicas o de laboratorio decidirán la retirada o no de los antibióticos. Como medida de prevención se recomienda la vacunación antineumocócica en la población de riesgo. A pesar de que se ha propuesto el uso de corticosteroides en dosis moderadas-bajas para el tratamiento de la neumonía por gripe A/H1N, con la finalidad de mejorar la lesión pulmonar aguda, hasta el presente no existe evidencia científica suficiente que permita recomendar el uso de esteroides en estos pacientes. El tratamiento del síndrome de distrés respiratorio agudo en pacientes con gripe A/H1N1 debe basarse en el empleo de estrategias ventilatorias protectoras del pulmón (volumen tidal < 10 ml/kg y presión plateau < 35 mmHg) y utilización de presión positiva al final de la espiración alta ajustada a la mecánica pulmonar del paciente, combinadas con el empleo de ventilación en decúbito prono, relajación muscular y maniobras de reclutamiento. La ventilación mecánica no invasiva no puede ser considerada una técnica de elección en los pacientes con síndrome de distrés respiratorio agudo, aunque podría ser útil en centros de gran experiencia y en casos de insuficiencia respiratoria asociados a reagudización de enfermedad pulmonar obstructiva crónica o insuficiencia cardiaca.

Obesity appears to be the most frequent clinical component in metabolic syndrome. Subcutaneous fat, independent from visceral fat, is still controversial as a marker of the pathophysiology of insulin resistance. An open parallel-group clinical trial was performed of 12 women (age 30-40 years), with BMI from 30-33 kg/m2 and fasting glucose &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; or =110 mg/dl. 6 women were included in the &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;liposuction plus diet&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; group, and 6 were included in the &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;diet-only&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; group. Metabolic profile, including insulin tolerance test (ITT), leptin and tumor necrosis factor alpha (TNFalpha), was performed at baseline, 1 and 6 months in both groups. Subcutaneous and visceral fat was quantified with spiral tomography at baseline and after 6 months. Friedman and Wilcoxon test were used for intra-group differences, Mann-Whitney U for differences between groups, and Spearman test for correlation, with significance set at P&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.05. No difference existed between groups regarding clinical characteristics and metabolic profile. In the liposuction group, the increase in insulin sensitivity was (3.8+/-0.86, 3.1+/-0.85, 4.5+/-1.02 %/min, P=0.08. Insulin sensitivity did not correlate with subcutaneous fat, leptin, or TNFalpha. Leptin diminished at 1 month (52.7+/-6.04 vs 31.6+/-11.9), P=0.028, and correlated with the subcutaneous fat (r=0.957). In the diet-only group, TNFalpha diminished at 6 months, P=0.046. Subcutaneous abdominal fat correlates with leptin; nevertheless, it is a weak marker for TNFalpha and insulin sensitivity.
