Type of hospitalisations and in-hospital outcomes in the Italian coronary care unit network at the time of COVID-19 pandemic: the BLITZ-COVID19 Registry.

OBJECTIVE: The aim of the study was to describe the epidemiology and outcome of patients hospitalised during the COVID-19 pandemic in intensive cardiac care units (ICCs). DESIGN: Non-interventional, retrospective and prospective, nationwide study. SETTING: 109 private or public ICCs in Italy. PARTICIPANTS: 6054 consecutive patients admitted to Italian ICCs during COVID-19 pandemic. PRIMARY AND SECONDARY OUTCOME MEASURES: To obtain accurate and up-to-date information on epidemiology and outcome of patients admitted to ICCs during the COVID-19 pandemic, the impact that the COVID-19 infection may have determined on the organisational pathways and in-hospital management of the various clinical conditions being admitted to ICCs. RESULTS: Acute coronary syndromes were the most frequent ICC discharge diagnoses followed by heart failure and hypokinetic arrhythmias. The prevalence of COVID-19 positivity was approximately 3%. Most patients with a COVID-19 diagnosis at discharge (52%) arrived to ICC from other wards, in particular 22% from non-cardiology ICCs. The overall mortality was 4.2% during ICC and 5.8% during hospital stay. The cause of in-hospital death was cardiac in 74.4% of the cases, non-cardiovascular in 13.5%, vascular in 5.8% and related to COVID-19 in 6.3% of the patients. CONCLUSIONS: This study provides a unique nationwide picture of current ICC care during COVID-19 pandemic. TRIAL REGISTRATION NUMBER: NCT04744415.

Outcomes Related to Antiplatelet Therapy in a High-Risk ST-Segment Elevation Myocardial Infarction Population: A Retrospective Real-World Analysis of an Italian ECMO Center.

AIM: To evaluate outcomes related to antiplatelet therapy in patients with ST-elevation myocardial infarction (STEMI) admitted to the San Gerardo Hospital in Monza, an extracorporeal membrane oxygenation (ECMO) reference center in the Monza-Brianza area. METHODS: This retrospective study enrolled patients with STEMI hospitalized between 2013 and 2017. RESULTS: This study included 653 patients (mean age: 67.5 years, 71% male). Across the study period, ticagrelor use showed consistent increases, from 22% of patients during 2013 to 85% in 2017. Cardiac arrest prehospitalization occurred in 100 patients (15.3%), either at home (n = 85, 13.0%) or during transfer (n = 15, 2.3%); 46 patients underwent ECMO for refractory cardiac arrest. Rates of 90-day survival (hazard ratio [HR]: 2.4, 95% confidence interval [CI]: 1.3-4.4, P = .004) and ST resolution (odds ratio [OR]: 2.5, 95% CI: 1.6-4.1, P = .000) were higher with ticagrelor than with other antiplatelet agents. When analyzed by each agent, patients on ticagrelor had longer survival (HR: 0.4, 95% CI: 0.2-0.8, P = .008) than patients on clopidogrel and more frequent ST resolution than those on clopidogrel or prasugrel (OR: 0.4, 95% CI: 0.2-0.7, P = .002 and OR: 0.4, 95% CI: 0.2-0.7, P = .006). There was no difference in mortality between ticagrelor and prasugrel. CONCLUSIONS: Changes in the treatment of high-risk patients with STEMI over time are in line with changes in treatment guidelines. In these patients, ticagrelor is associated with significantly improved 90-day mortality compared with clopidogrel.

Is response to radiotherapy in patients related to the severity of pretreatment pain?

PURPOSE: The primary objective of this study was to determine whether there is a relationship between the severity of pretreatment pain and response to palliative radiotherapy (RT) for painful bone metastases. METHODS AND MATERIALS: The database for patients with bone metastases seen at the Rapid Response Radiotherapy Program at the Odette Cancer Center from 1999 to 2006 was analyzed. The proportion of patients with mild (scores 1-4), moderate (scores 5-6), or severe (scores 7-10) pain at baseline who experienced a complete response, partial response, stable response, or progressive response after palliative RT was determined according to International Bone Metastases Consensus definitions. RESULTS: During the 7-year study period 1,053 patients received palliative radiation for bone metastases. The median age was 68 years and the median Karnofsky performance status was 70. Of the patients, 53% had a complete or partial response at 1 month, 52% at 2 months, and 54% at 3 months post-RT. CONCLUSIONS: There was no significant difference in terms of the proportion of responders (patients with complete or partial response) and nonresponders in terms of painful bone metastases among patients presenting with mild, moderate, or severe pain. Patients with moderate pain should be referred for palliative RT.

Symptom clusters in patients with cancer with metastatic bone pain.

PURPOSE: The primary objective was to explore how patients' worst pain clustered together with functional interference items. Secondary objectives were to determine whether symptom clusters change with palliative radiotherapy (RT) and to compare the difference between responders and nonresponders to radiation. MATERIALS/METHODS: Worst pain at the site of treatment and functional interference scores were assessed using the Brief Pain Inventory (BPI). Patients provided their scores at baseline, 4, 8, and 12 weeks post-RT. A principal component analysis was performed on the 8 items (worst pain and 7 functional interference items) at all time points to determine interrelationships between symptoms. Principal components with an eigenvalue higher than 0.90 and explaining more than 10% of the variance were selected. The Cronbach alpha statistic was used to estimate the internal consistency and reliability of the derived clusters at baseline and at subsequent follow-ups. Robust relationship and correlation among symptoms were displayed with a biplot graphic. RESULTS: From May 2003 to January 2007, 348 patients with bone metastases that were referred for palliative RT were accrued into the study. There were 206 males (59%) and 142 females (41%), with a median age of 68 years (range, 30-91). Lung (26%), breast (25%) and prostate (24%) were the most common primary cancer sites. Treatment ranged from single to multiple fractions, with the majority of patients receiving a single 8 Gy (58%) and 20 Gy/5 (35%). The most prevalent sites of RT were spine (31%), pelvis (16%), and hips (15%). Two symptom clusters were identified. Cluster 1 included walking ability, general activity, normal work, enjoyment of life and worst pain. Cluster 2 included relations with others, mood and sleep. The two clusters at baseline accounted for 67% of the total variance with a Cronbach alpha of 0.87 and 0.70, respectively. In responders to radiation treatment, the two symptom clusters disintegrated at 4, 8, and 12 weeks post-RT. All symptom severity items improved over time (p < 0.0001). In nonresponders, two clusters had disappeared at week 4, reemerged at week 8, and disintegrated at week 12. CONCLUSION: Symptom clustering has proved to be therapeutically important because treatment of one symptom may affect others within the same cluster. The significant correlations between worst pain and the functional interference items reaffirm the importance of pain reduction as a treatment goal for palliative radiotherapy. By treating a patient's symptom of worst pain, it would subsequently ease their response burden on their daily functional activities by decreasing symptom severity, increasing function, and improving overall quality of life.

Effects of extracorporeal cardiopulmonary resuscitation on neurological and cardiac outcome after ischaemic refractory cardiac arrest.

BACKGROUND: Extracorporeal cardiopulmonary resuscitation is increasingly recognised as a rescue therapy for refractory cardiac arrest, nevertheless data are scanty about its effects on neurologic and cardiac outcome. The aim of this study is to compare clinical outcome in patients with cardiac arrest of ischaemic origin (i.e. critical coronary plaque during angiography) and return of spontaneous circulation during conventional cardiopulmonary resuscitation vs refractory cardiac arrest patients needing extracorporeal cardiopulmonary resuscitation. Moreover, we tried to identify predictors of survival after successful cardiopulmonary resuscitation. METHODS: We enrolled 148 patients with ischaemic cardiac arrest admitted to our hospital from 2011-2015. We compared clinical characteristics, cardiac arrest features, neurological and echocardiographic data obtained after return of spontaneous circulation (within 24 h, 15 days and six months). RESULTS: Patients in the extracorporeal cardiopulmonary resuscitation group ( n=63, 43%) were younger (59±9 vs 63±8 year-old, p=0.02) with lower incidence of atherosclerosis risk factors than those with conventional cardiopulmonary resuscitation. In the extracorporeal cardiopulmonary resuscitation group, left ventricular ejection fraction was lower than conventional cardiopulmonary resuscitation at early echocardiography (19±16% vs 37±11 p<0.01). Survivors in both groups showed similar left ventricular ejection fraction 15 days and 4-6 months after cardiac arrest (46±8% vs 49±10, 47±11% vs 45±13%, p not significant for both), despite a major extent and duration of cardiac ischaemia in extracorporeal cardiopulmonary resuscitation patients. At multivariate analysis, the total cardiac arrest time was the only independent predictor of survival. CONCLUSIONS: Extracorporeal cardiopulmonary resuscitation patients are younger and have less comorbidities than conventional cardiopulmonary resuscitation, but they have worse survival and lower early left ventricular ejection fraction. Survivors after extracorporeal cardiopulmonary resuscitation have a neurological outcome and recovery of heart function comparable to subjects with return of spontaneous circulation. Total cardiac arrest time is the only predictor of survival after cardiopulmonary resuscitation in both groups.

Epilepsy and trimethylaminuria: A new case report and literature review.

Trimethylaminuria is a metabolic disorder characterized by the excessive excretion of trimethylamine in bodily secretions, which confers a very unpleasant odour resembling that of dead fish. Literature reports only two cases affected by trimethylaminuria and epilepsy. We describe a third patient who, from the age of seven, was affected by temporal focal seizures with nocturnal episodes of nausea, vomiting, anxiety and autonomic activation followed by headache. EEG showed focal paroxysmal abnormalities prevailing on the right temporo-parieto-occipital regions. We began administering levetiracetam and seizures stopped. Our patient also showed learning disabilities despite a normal intelligence quotient (IQ), while another described patient had an IQ varying from borderline to mild mental retardation. We discuss the association between trimethylaminuria and epilepsy, and formulate some hypotheses on the relationship between trimethylamine convulsive effect and the anticonvulsive role of levetiracetam.

Effects of heating on virgin olive oils and their blends: focus on modifications of phenolic fraction.

The phenolic profiles of two different virgin olive oils and their admixtures in different percentages have been analyzed after heating treatments by microwave or conventional oven. Changes in the phenolic profile upon heating were evaluated by chromatographic and spectroscopic methods, also monitoring the antioxidant activity by ABTS(*+) test. 3,4-DHPEA-EA, p-HPEA-EA, and EA showed the highest decreases after thermal treatments. The only compounds that showed a clear increase with heating, in particular by conventional oven, were the dialdehydic form of elenolic acid (EDA) and p-hydroxyphenylethanol linked to the dialdehydic form of elenolic acid (p-HPEA-EDA). A comparison between the variations after heating of the sum of monoaldehydic and dialdehydic forms of phenolic compounds obtained by using different analytical approaches (HPLC-DAD/MSD and 1D and 2D NMR spectroscopy) was made. The results showed a good agreement of these two high-resolution techniques.

New isatin derivatives with antioxidant activity.

The reaction between isatin and 2,5-dimethoxyaniline is described. The main product was identified as 3,3-bis(4-amino-2,5-dimethoxyphenyl)-1,3-dihydroindol-2-one. The antioxidant activity of the compounds isolated was evaluated with two methods. Three published antitumor E-3-(2-chloro-3-indolylmethylene)1,3-dihydroindol-2-ones entered the same tests to search whether they are endowed with antioxidant activity too. 3,3-Bis(4-amino-2,5-dimethoxyphenyl)-1,3-dihydroindol-2-one and the three antitumor agents showed a good chemical antioxidant activity.

Retrospective assessment of cancer pain management in an outpatient palliative radiotherapy clinic using the Pain Management Index.

CONTEXT: The Pain Management Index (PMI) is a simple index linking the usual severity of cancer pain with the category of medication prescribed to treat it. Medication categories are derived from the World Health Organization's "analgesic ladder" approach to cancer pain, and the PMI is an indicator of the extent to which the medication prescribed corresponds to the recommended categories for mild, moderate, and severe pain. OBJECTIVES: The aim of this study was to assess prevalence of inadequate pain management in an outpatient palliative radiotherapy clinic using the PMI. METHODS: All patients with bone metastases referred for palliative radiotherapy from 1999 to 2006 were retrospectively analyzed for patient-rated pain scores (0-10 scale) and analgesic consumption. Pain scores were assigned 0, 1, 2, and 3 when patients reported no pain (0), mild (1-4), moderate (5-6), or severe pain (7-10), respectively. Analgesic scores of 0, 1, 2, and 3 were assigned when patients were prescribed no pain medication, nonopioids, "weak" opioids, and "strong" opioids, respectively. The PMI score was calculated by subtracting the pain score from the analgesic score. A negative PMI score was considered an indicator of potentially inadequate pain management by the prescriber. Descriptive statistics, Pearson's r correlation, and univariate and multivariate logistic regression analysis were used to determine the relationship of PMI over time, and the relationship with predictive factors. RESULTS: One thousand patients were included from January 1999 to December 2006. A negative PMI was calculated for 25.8% of patients at initial consultation. Prevalence of negative PMI significantly increased over years (P<0.0001). Higher Karnofsky Performance Status (P<0.0001) and breast primary cancer site (P<0.0001) were significantly associated with negative PMI after adjusting for year variable. CONCLUSION: Despite publication of numerous cancer pain management guidelines, undermedication appears to be a persistent problem for patients with painful bone metastases referred for radiotherapy.

Has pain management in cancer patients with bone metastases improved? A seven-year review at an outpatient palliative radiotherapy clinic.

The primary objective of this study was to determine the prevalence of underdosage of analgesics for pain associated with bone metastases in outpatients referred to the Rapid Response Radiotherapy Program at the Odette Cancer Centre from 1999 to 2006. A prospective database containing data for all patients with bone metastases who were referred to the Rapid Response Radiotherapy Program for palliative radiotherapy from 1999 to 2006 was analyzed. The database included patient demographic information, including age at referral for radiation to the bone, gender, primary cancer site, and Karnofsky Performance Status; information on treatment-related factors, such as worst pain ratings and analgesic consumption in the past 24 hours (recorded as oral morphine equivalent doses); pain intensity ratings (none [rating=0], mild [rating=1-4], moderate [rating=5-6] or severe [rating=7-10]; and analgesic consumption (rated as none, nonopioids, weak opioids [e.g., codeine] and strong opioids [e.g., morphine and hydromorphone]). Patients who experienced moderate or severe pain and were prescribed no pain medication, nonopioids, or weak opioids were considered to be undermedicated. Between January 1999 and December 2006, 1,038 patients were included in the study database. Approximately 56% of patients were male and 44% were female. The median age was 68 years (range 28-95) and the median Karnofsky Performance Status was 70 (range 10-100). The percentages of undermedicated patients were 40% in 1999, 34% in 2000, 29% in 2001, 37% in 2003, 39% in 2004, 36% in 2005, and 48% in 2006. No appreciable decline was noted in the proportion of patients with moderate-to-severe pain who received no pain medication, nonopioids, or weak opioids during the study period. Despite the publication of pain management guidelines and the dissemination of data regarding the proportion of patients with bone metastases who are being prescribed inadequate analgesics, our findings suggest that a significant proportion of patients continue to be undermedicated.

Facile deferration of commercial fertilizers containing iron chelates for their NMR analysis.

Ethylenediamine-N,N'-bis(o-hydroxyphenylacetic) acid (o,o-EDDHA) is widely used in commercial formulations as a Fe(3+) chelating agent to remedy iron shortage in calcareous and alkaline soils. Commercially available o,o-EDDHA-Fe(3+) formulations contain a mixture of EDDHA regioisomers (o,p-EDDHA and p,p-EDDHA), together with other, still uncharacterized, products. NMR spectroscopy can be applied to their study as long as iron is accurately removed prior to the observation. This paper shows that it is possible to obtain a deferrated solution of the organic ligands present in commercial fertilizers containing the EDDHA-Fe(3+) chelate by treating the chelate with ferrocyanide, thus forming Prussian Blue that can be easily removed by centrifugation. This iron removal process does not cause significant losses of the o,o-EDDHA ligand or its minor structural isomers.
