BACKGROUND: With current literature quoting mortality rates up to 45%, emergency high-risk abdominal surgery has, compared with elective surgery, a significantly greater risk of death and major complications. The Surgical Apgar Score (SAS) is predictive of outcome in elective surgery, but has never been validated exclusively in an emergency setting. METHODS: A consecutive prospective single-center cohort study of 355 adults undergoing emergency high-risk abdominal surgery between June 2013 and May 2014 is presented...

Background: Several studies have shown that hyponatremia is associated with increased risk of rehospitalization and death in patients with heart failure. In these studies, chronic heart failure (CHF) patients with persistent hyponatremia were compared only with CHF patients with a normal sodium level at hospital admission. Aims: In the present retrospective study, conducted in a cohort of patients with recent acute decompensated heart failure (ADHF), all with hyponatremia ascertained at the time of hospital admission, we aimed to evaluate the effect of the normalization of serum sodium on the composite endpoint of short-term rehospitalization and mortality...

Modern healthcare systems are undergoing a paradigm shift from in-hospital care to in-home monitoring, leveraging the emerging technologies in the area of bio-sensing, wireless communication, mobile computing, and artificial intelligence. In-home monitoring promises to significantly reduce healthcare spending by preventing unnecessary hospital admissions and visits to healthcare professionals. Most of the in-home monitoring systems, proposed in the literature, focus on monitoring a set of specific vital signs...

We survey general results relating patterns of synchrony to network topology, applying the formalism of coupled cell systems. We also discuss patterns of phase-locking for periodic states, where cells have identical waveforms but regularly spaced phases. We focus on rigid patterns, which are not changed by small perturbations of the differential equation. Symmetry is one mechanism that creates patterns of synchrony and phase-locking. In general networks, there is another: balanced colorings of the cells. A symmetric network may have anomalous patterns of synchrony and phase-locking that are not consequences of symmetry...

BACKGROUND: Acute kidney injury (AKI) is common after surgery for acute aortic dissection (AAD) and increases in-hospital and long-term mortality. However, few data exist on the clinical and prognostic relevance of early preoperative AKI in patients with type A AAD. We aimed to determine the incidence and predictors of preoperative AKI and the impact of AKI on in-hospital outcomes in patients with type A AAD. METHODS: From May 2009 to June 2014, we retrospectively enrolled 178 patients admitted to our hospital within 48 h from symptom onset and receiving open surgery for type A AAD...

BACKGROUND AND AIMS: Stent retriever-based thrombectomy (SRT) may be beneficial in patients with large hemispheric stroke. Previous studies concluded that favorable outcomes are far less frequent after endovascular therapy in older patients but have not explored outcomes in the era of newer-generation stent retrievers. MATERIALS AND METHODS: Consecutive patients with large hemispheric stroke treated with SRT were included. We compared neurological and functional outcomes between patients younger and older than 80...

BACKGROUND: A sudden onset of neurological symptoms in patients is conventionally thought to be due to vascular phenomenon, with one common differential diagnosis being subarachnoid hemorrhage. Another important differential diagnosis is ischemic stroke. An uncommon cause of such acute symptoms can be hemorrhage in a pre-existing tumor, that is, intratumoral hemorrhage (ITH). PURPOSE: ITH is an important, though uncommon differential diagnosis in cases of sudden onset of neurological deterioration...

Background/Aims: EUS can detect bile duct stones (BDS) that are undetectable on multidetector computed tomography (MDCT). BDS associated with acute biliary pancreatitis (ABP) are small and tend to be excreted spontaneously. This study evaluated the usefulness of early EUS in patients with ABP and undetectable BDS on MDCT. Methods: Forty-one patients with ABP and undetectable BDS on MDCT underwent EUS within 24 hours of admission and were diagnosed with BDS, sludge, dilated common bile duct (CBD), or normal CBD...

We performed a multisite study to evaluate demographic and clinical conditions as potential modifiers of the particulate matter (PM)-mortality association. We selected 228,619 natural deaths of elderly persons (ages ≥65 years) that occurred in 12 Italian cities during the period 2006-2010. Individual data on causes of death, age, sex, location of death, and preexisting chronic and acute conditions from the previous 5 years' hospitalizations were collected. City-specific conditional logistic regression models were applied within the case-crossover "time-stratified" framework, followed by random-effects meta-analysis...
