Evaluation cardiologique préopératoire avant chirurgie non cardiaque: stratification du risque cardiovasculaire [Preoperative cardiac assessment before non-cardiac surgery: cardiac risk stratification].

Perioperative cardiac events occurring in patients undergoing non-cardiac surgery are a common cause of morbidity and mortality. Current guidelines recommend an individualized approach to preoperative cardiac risk stratification prior to non-cardiac surgery, integrating risk factors both for the patient (active cardiac conditions, clinical risk factors, functional capacity) and for the planned surgery. Preoperative cardiac investigations are currently limited to high-risk patients in whom they may contribute to modify the perioperative management. A multidisciplinary approach to such patients, integrating the general practitioner, is recommended in order to define an individualized peri-operative strategy.

Suivi du patient après transplantation cardiaque: monitoring et adaptation de l'immunosuppression [Monitoring and adjustment of immunosuppression after heart transplantation].

Heart transplantation remains the best therapeutic option for the treatment of end-stage heart failure. However, good survival rates can be obtained only if patients are closely monitored, particularly for their immunosuppressive regimens. Currently, a triple-drug regimen usually based on calcineurin-inhibitors (cyclosporin A or tacrolimus), anti-proliferative agents and steroids is used in most recipients. New agents such as the mTOR inhibitors, a more recently developed class of immunosuppressive drugs, can also be used in some patients. The aim of this article is to review currently used immunosuppressive regimens after heart transplantation, and to propose some individualized options depending on specific patient characteristics and recent pharmacological developments in the field.

Polimorfismos genéticos (en los genes OPRM1, BETA-ARRESTINA2,STAT6 y COMT) y su influencia en la tolerancia al tratamiento con opiáceos mayores en pacientes oncológicos

La morfina es l’opioid majoritàriament utilitzat en dolor oncològic, però existeix elevada variabilitat de resposta. Vam intentar correlacionar aquesta variabilitat amb polimorfismes genètics (Opmr-1, Beta-arrestina2, Stat6 i COMT, relacionats amb mecanismes d’acció opioids). Hem estudiat 29 pacients amb dolor (EVA superior o igual a 6) que van iniciar tractament amb morfina i vam avaluar eficacia i tolerancia a la morfina correlacionant-ho amb els polimorfismos que presentaven. Vam observar que els genotips CC/TC per β-arrestina2 i AA/GA per COMT i Oprm1 es podrien associar a millor resposta i menor toxicitat a la morfina, i els genotips AA/GA per STAT6 s’associaven significativament a menor toxicitat

Prise en charge de l'hémorragie du post-partum [Management of postpartum haemorrhage].

Today, postpartum hemorrhage remains a leading cause of maternal morbidity and mortality. Medical treatment, various surgical procedures and/or uterine artery embolisation have considerably reduced the risk of hysterectomy. It is important to identify the different risk factors of hemorrhage after delivery and to take the precautions to avoid it. A clear strategy defined by the obstetrical team is essential to decrease the delay in the management of this complication in order to increase the chances of a successful treatment.
