Causes of deaths in long-term care and hospice care facilities during the first year of COVID-19 pandemic: a snapshot of Italy during 2020

BACKGROUND

Older adults living in long-term care facilities (LTCF) have been severely affected by COVID-19. Hospice care (HC) facilities and palliative care are essential in treating patients dying from COVID-19. In Italy, little is known about the impact of COVID-19 on deaths in LTCF and the care provided in HC to COVID-19 patients.

AIM

To assess overall and case-specific mortality in 2020 in LTC and HC facilities in comparison to the previous five years (2015-2019).

METHODS

We performed a descriptive study using data derived from the Italian national "Cause of Death" registry-managed by the Italian National Institute of Statistics-on deaths occurred in LTC and HC facilities during 2020 and the period 2015-2019.

RESULTS

Number of deaths significantly increased in 2020 compared with 2015-2019 in LTCF (83,062 deaths vs. 59,200) and slightly decreased in hospices (38,788 vs. 39,652). COVID-19 caused 12.5% of deaths in LTCF and only 2% in hospices. Other than COVID-19, in 2020, cancer accounted for 77% of all deaths that occurred in HC, while cardiovascular diseases (35.6%) and psychotic and behavioral disorders (10%) were the most common causes of death in LTCF. Overall, 22% of the excess mortality registered in Italy during 2020 is represented by the deaths that occurred in LTCF.

DISCUSSION AND CONCLUSION

LTCF were disproportionally affected by COVID-19, while the response to the pandemic in HC was limited. These data can help plan strategies to limit the impact of future epidemics and to better understand residential care response to COVID-19 epidemic.

Impact of the Covid-19 pandemic on palliative care provision by a hospital-based unit: results from an observational study

Background Palliative care is a key approach in improving the quality of life of patients and their families facing the end-of-life care process. It is widely regarded as a public-health concern, especially considering the rapidly increasing end-of-life care needs worldwide. Its provision has been highly challenged by the COVID-19 pandemic emergency. Objective This study aims to analyse whether and to what extent the provision of Palliative Care to non-COVID patients provided by a hospital-based unit has changed during the COVID-19 pandemic. Material and methods A retrospective observational study was performed. All non-COVID patients admitted from October 1, 2019 to September 30, 2020 and evaluated by the hospital-based Palliative Care team were considered. Three time periods were considered: pre-lockdown, lockdown and post-lockdown. A trend analysis and multiple linear and logistic regressions to study and quantify the statistical significance of the associations were performed. Results A statistically significant positive linear trend of the number of hospitalized patients in need of Palliative Care was found over the study period. Compared to pre-lockdown, the rest of the study period presented more female and elderly patients, the length of stay and the number of patients discharged to a Hospice setting were significantly reduced. The waiting time did not change in lockdown but decreased in post-lockdown and the mortality rate was not significantly different. Also, the average number of Palliative Care consultations per patient significantly increased in the lockdown and post-lockdown. Discussion First, the significant admissions drop between the start of the pandemic and the following study period is in line with recent literature. The consequent rebound registered may be attributed to the high pressure from outside requiring admission and care. Second, the significantly older age of patients found during the lockdown than before the lockdown could be attributed to a "selection effect" of young patients, more able to delay hospitalization than the elderly, also in line with recent literature. Third, the shorter waiting time for Palliative Care activation the post-lockdown compared to the pre-lockdown period could be due to both increased hospital efficiency and to the greater pressure to discharge patients during the post-lockdown period. Also, the significant reduction in the lockdown and post-lockdown of the length of stay after Palliative Care activation could be explained considering both the greater receptivity of healthcare services outside the hospital, such as Hospices, and the greater pressure on hospital wards to discharge. Fourth, the unchanged in-hospital mortality rate remained over the entire period could be an indication of the high quality of care provided by this hospital setting to fragile patients, which is to be noted especially considering the average mortality rate registered during pandemic context in healthcare facilities. Conclusions The study aimed to quantify the impact of the COVID-19 on the provision of Palliative Care by a hospital-based team. We believe it might represent an innovative contribution and we hope similar research will be produced in order build the evidence for future challenges in this field.

Lacosamide on background eeg activity in brain tumor-related epilepsy patients: A case series study

OBJECTIVE

Therapeutic doses of antiepileptic drugs (AEDs) may alter EEG background activity, which is considered an index of the functional state of the brain. Quantitative analysis (qEEG) of EEG background activity is a valid instrument to assess the effects of many centrally active drugs on the central nervous system, including AEDs. Lacosamide (LCM) is a new AED that could be a valid therapeutic choice in patients with brain tumor-related epilepsy (BTRE).

METHODS

We used qEEG to analyze the possible effect of LCM as an add-on, on background EEG activity after 4 months in patients with BTRE.

RESULTS

We consecutively recruited sixteen patients with BTRE: Five dropped out for disease progression, five for scarce compliance, and six completed the study. For these reasons qEEG was performed at first visit and after 4 months only in six patients. For all frequency bands, LCM revealed no changes of mean relative power during rest with eyes closed, hyperpnoea (HP), and mental arithmetic task (MA); significant increment was found only in the theta mean relative power during opening and closing eyes (BR). After four months of therapy with LCM, one patient was seizure free, four had a seizure reduction ≥50%, and one showed a worsening in seizure frequency <50%.

CONCLUSION

Despite the limitation of a small series, these findings suggest that LCM seems to have only a mild interference on EEG background activity and confirm that LCM has a good efficacy on seizure control in patients with BTRE. This is the first study that evaluates the effect of LCM on background EEG activity, using qEEG in BTRE patients. Future research in this area could include prospective studies with qEEG for a longer follow-up period to assess the impact of AEDs on brain functions in this particular fragile patient population.

Neuropsychiatric adverse events of antiepileptic drugs in brain tumour-related epilepsy: an Italian multicentre prospective observational study

BACKGROUND AND PURPOSE

We assessed the prevalence and magnitude of neuropsychiatric adverse events (NPAEs) associated with antiepileptic drugs (AEDs) among patients with brain tumour-related epilepsy (BTRE).

METHODS

This observational, prospective, multicentre study enrolled 259 patients with BTRE after neurosurgery. All patients received AED monotherapy. Efficacy was assessed through clinical diaries, whereas NPAEs were collected using the Neuropsychiatric Inventory Test-12 questionnaire at baseline and after 5 months.

RESULTS

Tumour localization in the frontal lobe was associated with a higher prevalence of NPAEs (odds ratio, 7.73; P < 0.001). Independent of tumour localization, levetiracetam (LVT) treatment was associated with higher prevalence and magnitude of NPAEs (odds ratio, 7.94; P < 0.01) compared with other AEDs. Patients with oligodendroglioma reported more NPAEs than patients with other tumour types. NPAEs were not influenced by chemotherapy, radiotherapy or steroid treatment. Evaluating non-neurobehavioural adverse events of AEDs, no significant differences were found among AEDs, although patients treated with old AEDs had a higher prevalence of adverse events than those treated with new AEDs.

CONCLUSIONS

Both tumour localization in the frontal lobe and LVT treatment are associated with a higher risk of NPAEs in patients with BTRE. LVT is regarded as a first-line option in patients with BTRE because of easy titration and few significant drug-to-drug interactions. Thus, as NPAEs lead to poor compliance and a high dropout rate, clinicians need to accurately monitor NPAEs after AED prescription, especially in patients with frontal lobe tumours receiving LVT.

Effect of high dose cytosine arabinoside on quantitative EEG in patients with acute myeloid leukemia

Background EEG activity is considered an index of functional state of brain. Chemotherapy (CT), used for non-central nervous system (CNS) cancer, can cross the blood brain barrier and contribute to changes in the functional state of brain that can alter background EEG activity. Quantitative EEG (qEEG) is superior to conventional EEG in the detection of subtle alterations of EEG background activity and for this reason, the use of qEEG might assist the clinician in evaluating the possible effect of CT on the CNS. The nucleoside analog cytosine arabinoside (Ara-C) is one of the milestone chemotherapeutic agents used for treatment of acute myeloid leukemia (AML). Our observational study evaluates the possible effect of Ara-C on the qEEG of patients with AML, without CNS involvement. We conducted an observational study on newly diagnosed AML patients without CNS involvement, undergoing treatment with Ara-C to analyze the possible effect of Ara-C high doses on EEG background activity using qEEG analyses. A total of nine AML patients, 5 with Ara-C i.v. high dose (≥3 g/m(2) die), 4 with standard dose (100 mg/m(2) die) underwent qEEG (at rest, during hyperpnoea, mental arithmetic task and blocking reaction). We compared the EEG background activity of the two groups at baseline and after 6 months. Statistical analysis showed no significant differences between the two groups in mean relative power for all frequency bands, at rest and during hyperpnoea, mental arithmetic task and blocking reaction. Our data indicate that high dose Ara-C i.v. did not induce significant changes on EEG background activity in our patients. Future research in this area could include prospective studies that would combine qEEG and neuropsychological testing to assess the impact of CT on brain functions.

Theta-burst stimulation-induced plasticity over primary somatosensory cortex changes somatosensory temporal discrimination in healthy humans

Background

The somatosensory temporal discrimination threshold (STDT) measures the ability to perceive two stimuli as being sequential. Precisely how the single cerebral structures contribute in controlling the STDT is partially known and no information is available about whether STDT can be modulated by plasticity-inducing protocols.

Methodology/Principal Findings

To investigate how the cortical and cerebellar areas contribute to the STDT we used transcranial magnetic stimulation and a neuronavigation system. We enrolled 18 healthy volunteers and 10 of these completed all the experimental sessions, including the control experiments. STDT was measured on the left hand before and after applying continuous theta-burst stimulation (cTBS) on the right primary somatosensory area (S1), pre-supplementary motor area (pre-SMA), right dorsolateral prefrontal cortex (DLPFC) and left cerebellar hemisphere. We then investigated whether intermittent theta-burst stimulation (iTBS) on the right S1 improved the STDT. After right S1 cTBS, STDT values increased whereas after iTBS to the same cortical site they decreased. cTBS over the DLPFC and left lateral cerebellum left the STDT statistically unchanged. cTBS over the pre-SMA also left the STDT statistically unchanged, but it increased the number of errors subjects made in distinguishing trials testing a single stimulus and those testing paired stimuli.

Conclusions/Significance

Our findings obtained by applying TBS to the cortical areas involved in processing sensory discrimination show that the STDT is encoded in S1, possibly depends on intrinsic S1 neural circuit properties, and can be modulated by plasticity-inducing TBS protocols delivered over S1. Our findings, giving further insight into mechanisms involved in somatosensory temporal discrimination, help interpret STDT abnormalities in movement disorders including dystonia and Parkinson's disease.

EEG patterns and epileptic seizures in acute phase stroke

BACKGROUND

The rate of early post-stroke epileptic seizures ranges from 2 to 33%. This wide range is likely due to differences in study design, patient selection and type of neurophysiological monitoring. Electroencephalography (EEG), which is not used in the routine work-up of acute stroke, is the best neurodiagnostic technique for detecting epileptic activity, especially in patients with non-convulsive post-stroke epileptic activity. The aim of this study was to analyze patterns on EEGs performed within 24 h of stroke onset, and to investigate correlations between these patterns and the occurrence of early epileptic seizures and status epilepticus (SE), vascular risk factors, stroke subtypes and short-term outcome.

METHODS

We prospectively studied 232 patients (mean age 71 ± 12 years; 177 ischemic strokes and 55 hemorrhagic). EEG recording was performed within 24 h from hospitalization. The follow-up lasted 1 week.

RESULTS

Fifteen patients (6.5%) had early seizures within 24 h; 10 of these patients had focal SE with or without secondary generalization. EEG revealed sporadic epileptiform focal abnormalities in 10% and periodic lateralized epileptiform discharges (PLEDs) in 6%. SE was recorded in 71.4% of patients with PLEDs. At the multivariate analysis, only early epileptic manifestations (p < 0.001) were independently associated with PLEDs.

CONCLUSIONS

Our study confirms that seizures are not frequent in the early phase of acute stroke and occur prevalently as focal SE at onset. EEG may help to detect specific patterns, such as PLEDs, that are closely related to early seizures. EEG monitoring should be performed in order to detect purely electrographic seizures.
