[The nurses' strike in the United Kingdom: the reasons, the debate and the implications]. / Lo sciopero degli infermieri nel Regno Unito: le ragioni, il dibattito e le implicazioni.

. The nurses' strike in the United Kingdom: an overview of the reasons, debate and implications. INTRODUCTION: In the UK, where the National Health Service (NHS) was founded, one of the most important and long-lasting strikes in nursing is taking place. AIM: To understand the historical, professional, political/social reasons for the UK nurse's strike. METHOD: Historical, scientific literature and data from key informant interviews have been analysed. Data has been summarized narratively. RESULTS: On 15th December 2022, more than 100,000 NHS nurses went on strike in England, Northern Ireland, and Wales asking for an increased salary; on the 6th and 7th of February and 1st of March the protest has continued. By improving pay, nurses believe the attractiveness of the profession can increase and counteract the loss of nurses who are leaving the public for the private sector, and the lack of attractiveness of the profession towards young people. The strike is organized by the Royal College of Nursing in a structured form which gives nurses precise information on how it should be explained to patients: according to a survey, 79% of the population supports the nurses' strike. However, not all agree with this strike action. DISCUSSION: The media, social media and professional debate is passionate with some polarization between who is in favor and who is against. Nurses strike not only for better wages but also to increase patient safety. What we see in the UK today is the result of years of austerity, lack of investment and health priorities: a similar situation experienced in several countries as well.

Midterm results of edge-to-edge mitral valve repair without annuloplasty.

OBJECTIVE: Edge-to-edge mitral valve repair is usually performed in association with annuloplasty, with rare exceptions. We retrospectively analyzed the results of ringless edge-to-edge repair, particularly in view of minimally invasive and percutaneous approaches. METHODS: From November 1993 to December 2001, 81 patients underwent edge-to-edge mitral repair without associated annuloplasty. The cause was degenerative in most patients. In 32 patients the annulus was severely calcified. Type I lesions were present in 6 patients, type II lesions in 60 patients, and type III lesions in 15 patients. A double-orifice repair was done in 69 patients, and paracommissural repair was done in 12 patients. In 5 patients edge-to-edge repair was used as a rescue procedure. RESULTS: There were 3 hospital and 4 late deaths, for a 4-year survival of 85% +/- 6.7%. At latest follow-up, 63 patients were in New York Heart Association classes I or II, and 9 patients were in classes III or IV. Nine patients required reoperation (89% +/- 3.9% overall freedom from reoperation at 4 years). Annular calcification was associated with a greater reoperation rate (77% +/- 22% vs 95% +/- 4.6% freedom from reoperation, P =.03). Intraoperative water testing and postrepair transesophageal echocardiography predicted late failure. Only 1 of 42 patients required reoperation in the follow-up period when annular calcification, rheumatic disease, or rescue procedure were not present as risk factors. CONCLUSIONS: Our data confirm overall suboptimal results of the edge-to-edge technique when annuloplasty is not added to the repair. Annular calcification, rheumatic cause, and edge-to-edge repair done as a rescue procedure were associated with the worst outcome. Midterm results in selected patients encourage future developments in catheter-based edge-to-edge procedures.

Surgical ablation of atrial fibrillation using the epicardial radiofrequency approach: mid-term results and risk analysis.

BACKGROUND: The minor technical and time requirements with respect to the maze operation combined with a comparable efficacy has led to an increasing popularity of left atrial approaches to treat atrial fibrillation. We report our experience with a left atrial procedure based on extensive use of epicardial radiofrequency ablation in an effort to minimize cardiac arrest time. METHODS: A total of 132 consecutive patients with atrial fibrillation (121 chronic, 11 paroxysmal) undergoing open heart surgery had combined intraoperative ablation. An original set of left atrial lesions was performed using a radiofrequency linear catheter. Most of the ablations were performed epicardially before aortic cross-damping. Patients with contraindications to the epicardial approach had the whole lesion set performed endocardially. RESULTS: The mean cardiac arrest time spent for open heart ablations was significantly shorter (5.2 +/- 0.9 minutes with modem catheters) when the epicardial approach was used (107 of 132 patients, 81%). Hospital mortality was 0.8%. Freedom from atrial fibrillation was 77% 3 years after the operation. Of all the variables analyzed, only age at surgery and early postoperative arrhythmias increased the risk of recurrent atrial fibrillation. Overall 3-year survival was 94%. The 3-year actuarial freedom from stroke was 98%. No patient required implantation of a permanent pacemaker. Atrial contractility was recovered in all patients with stable sinus rhythm. CONCLUSIONS: Left atrial radiofrequency ablation allows recovery of sinus rhythm and atrial function in the great majority of patients with atrial fibrillation who undergo open heart surgery. The epicardial radiofrequency approach is a safe and effective means to cure atrial fibrillation with negligible technical and time requirements.

A novel technique for correction of severe tricuspid valve regurgitation due to complex lesions.

OBJECTIVES: Correction of tricuspid regurgitation due to complex lesions (not treatable with annuloplasty only) is associated with suboptimal results. To improve the efficacy of valve repair in this context, we developed a new surgical approach, which consists of stitching together the central part of the free edges of the leaflets producing a 'clover' shaped valve. Our preliminary experience with this novel technique is reported. METHODS: Between 2001 and 2003, 14 patients (mean age 57+/-17 years), with severe tricuspid regurgitation due to complex lesions, underwent valve repair with this novel approach in combination with annuloplasty. The aetiology of the disease was post-traumatic in five cases, degenerative in eight and secondary to dilated cardiomyopathy in one. Anterior leaflet prolapse/flail was present in most patients associated with posterior and/or septal leaflet prolapse or tethering. Annular and right ventricular dilatation was present in all cases. Mitral valve repair/replacement was concomitantly performed in nine patients. RESULTS: Hospital mortality was 7.1% (1/14). At follow-up extending to 22 months (mean 12+/-6.3), all survivors were asymptomatic. At the last echocardiogram tricuspid regurgitation was absent or mild in 13 patients and moderate in one. Mean tricuspid valve area and gradient were 4.2+/-0.4 cm(2) and 2.7+/-1.4 mmHg, respectively. CONCLUSIONS: Despite the short follow-up, this novel technique appears to be an easy, rapid and effective approach to correct severe tricuspid regurgitation due to complex lesions. Such a repair restored tricuspid valve competence, even in the presence of huge RV dilatation and pulmonary hypertension.

A method to avoid annular downsizing during knot tying.

Pericardial annuloplasty has been used as an alternative to prosthetic annuloplasty. One drawback of pericardial annuloplasty is the risk of cinching of tissues during knot tying, possibly leading to uncontrolled downsizing and to complications such as mitral stenosis and systolic anterior motion of the anterior leaflet. A simple modification of the sequence of knot tying is described to avoid this complication.

Cardiopulmonary bypass strategy during concomitant surgical treatment of mitral valve disease and atrial fibrillation.

In recent years, the popularity of simplified intraoperative ablation approaches to treat atrial fibrillation (AF) has been progressively increasing. Our group has described a left atrial procedure based on epicardial radio frequency ablation on cardiopulmonary bypass (CPB). We report our CPB and myocardial protection strategy in 157 patients who underwent AF ablation combined with open-heart surgery from February 1998 to February 2002. Since epicardial ablations are performed on CPB on the beating heart, the CPB strategy is crucial. Total normothermic CPB allows a safe dissection around the pulmonary veins on the decompressed heart; after the ablating catheter has been positioned, an adequate filling of the left atrium favours a uniform contact with the atrial wall. After crossclamping, low-flow retrograde cardioplegia delivery is administered while ablating endocardially to protect the main coronary arteries in the atrio-ventricular groove from radio frequency-related trauma. All patients were successfully weaned from CPB. Sinus rhythm was restored in 152 of 157 (96.8%) patients immediately after surgery. No procedure-related complications were recorded. Epicardial ablations allowed us to reduce significantly the aortic crossclamping time required for ablations. The conduct of CPB and myocardial protection play a central role in the surgical strategy by improving intraoperative feasibility and effectiveness of radio frequency ablation and preventing some of the potential postoperative complications related to the procedure.
