An ergonomic study of single-port versus multi-port laparoscopic mesh insertion for ventral hernia repair.

PURPOSE: To assess the mental effort and physical discomfort of placement of a prosthetic mesh into the abdominal cavity with single-incision laparoscopic surgery (SILS) or multi-port laparoscopic access for incisional ventral hernia repair. METHODS: A total of 10 surgeons with previous experience in conventional laparoscopic surgery performed four surgical tasks through a multi-port laparoscopic access and a SILS access in a porcine model during a first 4-hour working session and a second 2-hour working session. These tasks included (a) introduction of a prosthetic mesh for abdominal wall surgery, (b) manipulation of the mesh inside the abdomen, (c) manipulation of the laparoscopic instruments and (d) mesh insertion to the intraperitoneal abdominal wall and fixation with tackers. The level of mental effort was assessed with the Subjective Mental Effort Questionnaire (SMEQ) and physical discomfort with the Local Experienced Discomfort Scale (LED). RESULTS: Seventy percent were men, with a mean age of 45 years and a mean of 18 years of experience in practicing surgery. The SMEQ questionnaire showed a median physical effort of 24.4 (range 9-36.1) points for the multi-port laparoscopic access and 107.4 (range 74.7-128.4) for SILS (p < 0.01). Statistically significant differences between multi-port laparoscopic surgery and SILS were consistently demonstrated in all tasks as well as in both the 4-hour and 2-hour working sessions. The median (interquartile range) score of the LED scale was 12.5 (2-34.5) for tasks during multi-port laparoscopic surgery and 53.5 (29-89.2) for SILS (p < 0.001). All individual tasks were associated with a significantly higher physical effort for SILS than for conventional laparoscopic access, which were also independent of being performed during the 4-hour or 2-hour working periods. CONCLUSIONS: Placement and manipulation of a prosthetic mesh for incisional ventral hernia repair is more difficult with SILS than using multi-port laparoscopic access, independently of previous experience with standard laparoscopic techniques. This greater difficulty was observed both in terms of mental effort and physical discomfort. More experimental and clinical studies are needed to define specific training aspects and clinical advantages of incisional ventral hernia repair through SILS.

Nursing care in therapeutic hypothermia in neonates with hypoxic-ischaemic encephalopathy. Review of the literature. / Cuidados enfermeros a neonatos con encefalopatía hipóxico-isquémica en hipotermia terapéutica. Revisión bibliográfica.

INTRODUCTION: Hypoxic-ischaemic encephalopathy is one of the main causes of neurological damage in the new-born. Therapeutic hypothermia is the current treatment to reduce mortality and disability in new-borns with this condition. OBJECTIVE: To identify nursing care in new-borns with severe to moderate hypoxic-ischaemic encephalopathy, treated with active therapeutic hypothermia. MATERIALS AND METHODS: A review of the scientific literature was carried out in different databases (PubMed, Lilacs, IBECS, Cinhal, OvidSP, Cuiden, Embase and Cochrane Plus) over the last five years. The documentary assessment was carried out by peers and the quality was evaluated using the CEBM and GRADE scales. RESULTS: Of the 22 articles selected and reviewed, it is evident that therapeutic hypothermia is effective in reducing the mobility and mortality of neo-nates with hypoxic-ischaemic encephalopathy. Nursing care during hypothermia treatment focuses on four basic pillars: general care for stabilisation of the new-born, preparation of the material, administration of medical treatment in all its phases and emotional support of the family. CONCLUSIONS: Therapeutic hypothermia is effective in reducing the sequelae and mortality of neonates with hypoxic-ischaemic encephalopathy. Nursing care is essential throughout the treatment, in the early detection of complications in the infant and psychological support for parents. It is essential for nurses to receive training in this care.

The experiences of older individuals providing care to older dependents: A phenomenological study in Spain.

OBJECTIVE: Non-professional care provided in domestic settings by a family member or someone from the close environment and without a connection to a professional care service, is increasingly assumed by older people, mainly the spouses of those requiring care. The aim of this study was to describe the experience of older people providing care at home to older dependents. METHODS: A qualitative study was carried out to describe and explore the experience of older people, caregivers of dependent older people in the home. RESULTS: Four themes emerged as a result of the analysis: interpersonal relationships established in the caregivers' immediate environment; the need and request for public and private resources; consequences of providing care during old age; and adaptation to the circumstance of being a caregiver during old age. Older people who provide home-based care, experience their situation as stressful, feel that it limits their daily life, deprives them of their freedom, and affects their interpersonal relationships and social activities. DISCUSSION: Older caregivers learn quickly and can manage the skills issues. The volume of work is their challenge. Interpersonal relationships are altered depending on the length of time spent together and the demand for care. Public services and benefits are not adapted to the demands of caregivers or dependent persons.

Risk factors associated with adverse events in neonates with peripherally inserted central catheter. / Factores de riesgo asociados a eventos adversos en recién nacidos portadores de catéteres centrales de inserción periférica.

BACKGROUND: Peripherally inserted central catheters have become a priority in infants who require long-term intravenous therapy, but their use involves certain risks. OBJECTIVE: The aim of the study was to describe the occurrence of adverse events in newborns with peripherally inserted central catheters and to determine the risk factors associated with them. METHODS: A descriptive cross-sectional study was designed and performed. All neonates with peripherally inserted central catheters from October 1st, 2014 to September 30th, 2015 were included. The adverse events and sociodemographic and clinical variables related to neonates and analyzed catheters were recorded. RESULTS: A total of 140 catheters were placed in 116 infants. All of them were analyzed. Adverse events occurred in 16.4%: catheter-associated bacteraemia (5.7%), obstruction (5.7%), extravasation (2.1%) and phlebitis (2.1%), <27weeks of pregnancy (OR=1.2, P=.02), birth weight <1000g (OR=6.7, P=.02), with catheters in situ for longer than one week (OR=9.8, P=.02) and with perfusion of antibiotics per catheter (OR=1.3, P<.01). Phlebitis is associated with the insertion of the catheter in LL and head (OR=1.1, P=.03). Factors associated with bacteraemia risk with adjusted prevalence odds ratio are extremely low birth weight neonates (OR=6.38; P=.03) and with a catheter in situ for longer than one week (OR=9.41; P=.04). CONCLUSIONS: The periodic evaluation of catheter-related adverse events is very useful to prepare improvement plans. This will maximize safety for the most vulnerable newborns, especially those of extremely low birth weight that require very long treatments.

Personalization of a cardiac electromechanical model using reduced order unscented Kalman filtering from regional volumes.

Patient-specific cardiac modeling can help in understanding pathophysiology and therapy planning. However it requires to combine functional and anatomical data in order to build accurate models and to personalize the model geometry, kinematics, electrophysiology and mechanics. Personalizing the electromechanical coupling from medical images is a challenging task. We use the Bestel-Clément-Sorine (BCS) electromechanical model of the heart, which provides reasonable accuracy with a reasonable number of parameters (14 for each ventricle) compared to the available clinical data at the organ level. We propose a personalization strategy from cine MRI data in two steps. We first estimate global parameters with an automatic calibration algorithm based on the Unscented Transform which allows to initialize the parameters while matching the volume and pressure curves. In a second step we locally personalize the contractilities of all AHA (American Heart Association) zones of the left ventricle using the reduced order unscented Kalman filtering on Regional Volumes. This personalization strategy was validated synthetically and tested successfully on eight healthy and three pathological cases.
