Abstract
The objective of this study was to investigate the potential causes of high body temperature (Tb) during lactation in mice as a putative limit on energy intake. In particular we explored whether or not offspring contributed to heat retention in mothers while suckling. Tb and physical activity were monitored in 26 female MF1 mice using intraperitoneally implanted transmitters. In addition, maternal behaviour was scored each minute for 8 h d(-1) throughout lactation. Mothers that raised larger litters tended to have higher Tb while nursing inside nests (P < 0.05), suggesting that nursing offspring may have influenced heat retention. However, Tb during nursing was not higher than that recorded during other behaviours. In addition, the highest Tb during the observation period was not measured during nursing behaviour. Finally, there was no indication that mothers discontinued suckling because of a progressive rise in their Tb while suckling. Tb throughout lactation was correlated with daily increases in energy intake. Chronic hyperthermia during lactation was not caused by increased heat retention due to surrounding offspring. Other factors, like metabolic heat produced as a by-product of milk production or energy intake may be more important factors. Heat dissipation limits are probably not a phenomenon restricted to lactation.

Abstract
INTRODUCTION Colorectal cancer is the 3rd commonest cause of death from cancer: 5% of patients will develop lung metastases. The management of oligometastatic disease is based on the objective of optimal local control. STATE OF THE ART To date, no results from randomized control trials support the resection of pulmonary metastases in oligometastastic colorectal cancer patients. However, numerous series, mainly retrospective, report long-term survival for highly selected patients, with 5-year survival ranging from 45 to 65% in the most recent series. The consensual predictive factors of a good prognosis are: a disease free-interval>36 months, a number of metastases≤3, a normal level of carcino-embryonic antigen and the absence of hilar or mediastinal lymph node involvement. PERSPECTIVES Around 20 to 40% of patients will develop recurrence, probably linked to the presence of undetectable micrometastases. Therefore, experimental work is being undertaken to develop new treatment techniques such as isolated lung perfusion, radiofrequency ablation and stereotactic radiation therapy. CONCLUSION Highly selected patients suffering from colorectal cancer lung metastases could benefit from resection with improved survival and disease-control.

Abstract
Invasive fungal infections (IFI) remain life-threatening complications in haematological patients. The aim of the study was to present the experience of a single centre in the surgical treatment of pulmonary IFI. Between 1992 and 2014, 50 haematological patients with IFI underwent pulmonary resection. In 27 cases it was an emergency procedure to avoid haemoptysis (if the lesion threatened pulmonary vessels). The remaining 23 patients underwent elective surgery before new chemotherapy or stem-cell transplantation. Among these patients (median age: 54 years; range: 5-70 years), 92% had acute leukaemia and 68% were on haematological first-line therapy (receiving induction or consolidation chemotherapies). Invasive pulmonary aspergillosis and pulmonary mucormycosis were diagnosed in 37 and 12 patients, respectively. One patient had IFI due to Trichoderma longibrachiatum. All of the patients received antifungal agents. In the month preceding IFI diagnosis, 94% of patients had been neutropenic. At the time of surgery, 30% of patients were still neutropenic and 54% required platelet transfusions. Lobectomy or segmentectomy were performed in 80% and 20% of cases, respectively. Mortality at 30 and 90 days post-surgery was 6% and 10%, respectively. After surgery, median overall survival was 21 months; median overall survival was similar between patients with emergency or elective surgery and between the types of IFI (invasive pulmonary aspergillosis or pulmonary mucormycosis). However, overall survival was far better in haematological first-line patients or in those achieving a haematological complete response than in other patients (p <0.001). In pulmonary IFI, lung resection could be an effective complement to medical treatment in selected haematological patients.

Abstract
BACKGROUND Necrotizing soft tissue infections (NSTI) represent a rare but devastating disease for which the systemic manifestations have been poorly characterized. In an effort to define an optimal endpoint for clinical trials in this condition, the objective of this study was to establish the pattern of organ dysfunction over time and determine the correlation between organ dysfunction and clinical outcome in patients with NSTI. METHODS We conducted a multicenter, retrospective clinical study of patients with NSTI presenting to 12 academic medical centers in the U.S. during 2013. Patients with a diagnosis of NSTI confirmed by surgical findings were included. Organ dysfunction was assessed using a modified Sequential Organ Failure Assessment (SOFA) score (mSOFA: excluding liver) on admission and on hospital days 1, 2, 3, 7, 10, and 14. The presence of organ dysfunction on admission and resolution of organ dysfunction were correlated with clinical parameters, including intensive care unit (ICU)-free days (of 28 d), ventilator-free days, number of debridements, and mortality rate. The incidence of acute kidney injury (AKI) and recovery also were assessed. RESULTS There were 198 patients enrolled, of whom 62% were male, the mean age was 51 years, and 40% had monomicrobial infections. The mean mSOFA score on admission was 2.4 ± 3.0, with 49% of the patients having a score ≥2 and 35% a score of ≥3. Patients typically demonstrated worsening of the mSOFA score over the first 24 h followed by gradual resolution. An mSOFA ≥3 at admission was associated with a significant decrease in ventilator-free days (mean 20.1 vs. 25.6 days; p < 0.001); ICU-free days (15.2 vs. 23.1, p < 0.001); more debridements (mean 2.3 vs. 2.0; p = 0.11); a higher mortality rate (15.9% vs. 3.1%; p = 0.003); and a higher rate of AKI (59.4 vs. 35.9%; p < 0.001). The persistence of organ dysfunction (mSOFA >1) among survivors at day 14 was associated with fewer ICU-free days (17.8 vs. 23.6; p < 0.001) and ventilator-free days (23.6 vs. 27; p = 0.001) and a lower recovery rate from AKI (38.7% vs. 81.3%; p < 0.001). CONCLUSION Early development of systemic organ dysfunction in patients with NSTI is associated with higher morbidity and mortality rates. Failure of the resolution of organ dysfunction by day 14 forecasts a poor outcome. The mSOFA score may be a useful marker for patient selection for inclusion in interventional trials, and the resolution of organ dysfunction by day 14 may be an important clinical endpoint.

Abstract
Direct laryngoscopy (DL) is the most commonly used technique for tracheal intubation, but there is ongoing interest in new devices that have high success rates and are easily learned. The pediatric Airtraq (AT) is a recently developed intubation device that allows visualization of the glottis and intubation of the trachea without alignment of the oral, pharyngeal and tracheal axes. We studied the efficacy of the AT compared to the DL for laryngoscopy of young children with normal airway anatomy. In this prospective study, 49 children (5 yr and younger) scheduled for elective surgery under general anesthesia were randomized into two groups: intubation using direct laryngoscopy (DL group) and laryngoscopy using the Airtraq (AT group). Time to best view, time to intubate, first attempt success rate (FASR), and percentage of glottic opening seen (percentage of glottis opening score) were recorded. Data are presented as median and interquartile range. Time to best view was five (4, 7) sec in DL and five (4, 7.5) sec in AT. Time to intubate was 18 (14.7, 21) sec in DL and 22.5 (19.5, 25.5) sec in AT (P = 0.002). FASR was 100% in the DL and 83% in the AT. The percentage of glottis opening score was 80% (range 60-100%) in the DL and 100% (range 100-100%) in the AT (P < 0.001). In young children with normal airway anatomy, the AT provides a better view of the glottis than the standard laryngoscope, but it takes longer to intubate the trachea and the FASR is lower.
