A checklist-based survey for early mobilization of stroke unit patients in an Italian region.

BACKGROUND: Although early mobilization (EM) is recommended by most guidelines in acute stroke patients, there is a paucity of tools to perform a standardized patient risk assessment prior to EM in stroke units (SUs). OBJECTIVE: This survey aimed at assessing (1) the usefulness of an ad hoc checklist for a standardized approach to EM in SUs and (2) the relationship between EM achieved by this checklist and SU characteristics. METHODS: This survey was carried out in 10 SUs in Piedmont, Italy. The EM checklist was based on 15 "items", including quantitative/qualitative, clinical and management features. RESULTS: A total of 250 completed checklists were assessed. EM, defined as out-of-bed activity within 72 h of admission, was reached by 174 patients (69.6%), according to the checklist. There was a statistically significant association between the admission NIHSS score and EM. Hypotension at mobilization was observed in 29/250 patients (11.6%) and was significantly associated with EM. A total of 6 falls (2.4%) were reported. Nurses were most frequently involved in EM, either alone (40.8%) or with another professional. CONCLUSION: A large percentage of acute stroke patients managed to achieve a safe EM in the SUs that adopted the novel checklist. These results suggest that this checklist may well be a user-friendly, reliable tool to assist SU professionals in deciding whether to mobilize or not, by means of a standardized approach.

An integrated approach to the evaluation of patients with asymptomatic or minimally symptomatic hyperCKemia.

INTRODUCTION/AIMS: Currently, there are no straightforward guidelines for the clinical and diagnostic management of hyperCKemia, a frequent and nonspecific presentation in muscle diseases. Therefore, we aimed to describe our diagnostic workflow for evaluating patients with this condition. METHODS: We selected 83 asymptomatic or minimally symptomatic patients with persistent hyperCKemia for participation in this Italian multicenter study. Patients with facial involvement and distal or congenital myopathies were excluded, as were patients with suspected inflammatory myopathies or predominant respiratory or cardiac involvement. All patients underwent a neurological examination and nerve conduction and electromyography studies. The first step of the investigation included a screening for Pompe disease. We then evaluated the patients for myotonic dystrophy type II-related CCTG expansion and excluded patients with copy number variations in the DMD gene. Subsequently, the undiagnosed patients were investigated using a target gene panel that included 20 genes associated with isolated hyperCKemia. RESULTS: Using this approach, we established a definitive diagnosis in one third of the patients. The detection rate was higher in patients with severe hyperCKemia and abnormal electromyographic findings. DISCUSSION: We have described our diagnostic workflow for isolated hyperCKemia, which is based on electrodiagnostic data, biochemical screening, and first-line genetic investigations, followed by successive targeted sequencing panels. Both clinical signs and electromyographic abnormalities are associated with increased diagnostic yields.

A cross-sectional study on the association between Helicobacter pylori infection and headache.

BACKGROUND: The relationship between chronic Helicobacter pylori (HP) infection and headache has been discussed for long; nevertheless, the results of the studies are still contrasting. OBJECTIVE: This cross-sectional study is aimed to investigate a possible association between HP and headache, mainly migraine. METHODS: We screened, by a self-administered questionnaire, the subjects undergoing a breath test or an esophagogastroduodenoscopy. Migraine was diagnosed according to the international criteria. RESULTS: A total of 3914 patients underwent a breath test and 2200 an esophagogastroduodenoscopy at two hospitals, in Piedmont (Italy), in a 5-year period; a total of 1362 questionnaires were included in the study. The mean age of the subjects was 53 years; there were 777 women (57%). HP was detected in 364 (27%) subjects. A total of 702 (51%) subjects suffered from headache: migraine with aura was diagnosed in 176 subjects (176/702, i.e., 25% of the headache group; 176/1362, i.e., 13% of the total population); migraine without aura in 98 subjects (98/702, i.e., 14% of the headache group; 98/1362, i.e., 7% of the total). The logistic regression model did not detect any significant association between HP infection and headache, while a significant association between HP and headache frequency (p =0.009) was found, independently of age, gender, comorbidity, and diagnostic category. CONCLUSION: Our study does not reveal an association between chronic HP infection and migraine. However, since HP is significantly associated with higher headache frequency, a role for HP as a risk factor for headache chronification, possibly underlain by inflammatory mechanisms, may be supposed.

Characterization and management of neurological adverse events during immune-checkpoint inhibitors treatment: an Italian multicentric experience.

BACKGROUND: Neurological immune-related adverse events (nirAEs) are rare toxicities of immune-checkpoint inhibitors (ICI). With the increase of ICI oncological indications, their incidence is growing. Their recognition and management remain nevertheless challenging. METHODS: A national, web-based database was built to collect cases of neurological symptoms in patients receiving ICI and not attributable to other causes after an adequate workup. RESULTS: We identified 27 patients who developed nirAEs (20 males, median age 69 years). Patients received anti-PD1/PDL1 (78%), anti-CTLA4 (4%), or both (19%). Most common cancers were melanoma (30%) and non-small cell lung cancer (26%). Peripheral nervous system was mostly affected (78%). Median time to onset was 43.5 days and was shorter for peripheral versus central nervous system toxicities (36 versus 144.5 days, p = 0.045). Common manifestations were myositis (33%), inflammatory polyradiculoneuropathies (33%), and myasthenia gravis (19%), alone or in combination, but the spectrum of diagnoses was broad. Most patients received first-line glucocorticoids (85%) or IVIg (15%). Seven patients (26%) needed second-line treatments. At last follow-up, four (15%) patients were deceased (encephalitis, 1; myositis/myasthenia with concomitant myocarditis, 2; acute polyradiculoneuropathy, 1), while seven (26%) had a complete remission, eight (30%) partial improvement, and six (22%) stable/progressing symptoms. ICI treatment was discontinued in most patients (78%). CONCLUSIONS: Neurological irAEs are rare but potentially fatal. They primarily affect neuromuscular structures but encompass a broad range of presentations. A prompt recognition is mandatory to timely withheld immunotherapy and administrate glucocorticoids. In corticoresistant or severely affected patients, second-line treatments with IVIg or plasmapheresis may result in additional benefit.

Two-year follow-up during fingolimod treatment in a pediatric multiple sclerosis patient still active on first-line treatment.

Treatment of pediatric multiple sclerosis (MS) has been increasingly debated in the last few years due to limited knowledge of treatment strategies and therapeutic options. When MS develops at a young age, it usually has a very inflammatory disease course, with many relapses and disease activity as seen in magnetic resonance imaging (MRI). Therefore, treatment with immunomodulatory drugs may be beneficial in these patients. However, limited data are available to date on the treatment of pediatric MS. Although observational, prospective, and retrospective studies provide some information on its treatment course, only one clinical trial in pediatric patients has been published, the PARADIGMS trial, which showed an 82% reduction in relapse rate with fingolimod (0.5 mg/day) versus interferon ß-1a (30 µg once weekly intramuscularly). Here, we present the case of a pediatric patient with MS (age of onset, 13 years), who was initially treated with interferon ß-1a for 2 years and subsequently switched to fingolimod, owing to clinical and radiological activity despite treatment with interferon ß-1a.

Diagnostic Accuracy of a Bedside Screening Tool for Dysphagia (BSTD) in Acute Stroke Patients.

BACKGROUND AND PURPOSE: an estimated 40-80% of acute ischemic stroke patients have dysphagia and about 14% develop stroke-associated pneumonia. However, it may be difficult to detect swallowing problems at admission. Moreover, there might not be an on-duty specialist skilled in the diagnosis of this condition. This study aimed at developing a user-friendly bedside examination to identify the risk of dysphagia in stroke patients at hospital admission. METHODS: a diagnostic accuracy study was carried out to assess the concurrent validity of a simple Bedside Screening Tool for Dysphagia (BSTD) in acute stroke. All the consecutive stroke patients admitted between January and April 2018 were enrolled. Sensitivity, specificity, positive (PPV), negative predictive values (NPV) and the Cohen K concordance index scores, reported by nurses and speech-pathologists, were assessed. RESULTS: a total of 67/120 patients (55.8%) were male; overall average age was 67.4 (range 45-91) and 80.8% of the whole population had a history of ischemic stroke. The nursing staff identified 33.3% of dysphagia cases at admission and the speech pathologists 30%. The Cohen K was 0.92 (optimal concordance when K was > 0.8), sensitivity was 100%, specificity 95.2%, PPV 90% and NPV 100%. CONCLUSIONS: our BSTD had a 100% negative predictive value, indicating that this screening test is very useful in ruling out/confirming dysphagia in acute stroke patients.

Migraine Awareness in Italy and the Myth of "Cervical Arthrosis".

OBJECTIVE: The primary aim of this study was to assess the degree of awareness migraine patients had of their condition. The secondary aims were to evaluate the frequency of an incorrect diagnosis of "cervical arthrosis" in patients unaware of having migraine and to compare the clinical features, diagnostic investigation, and treatment strategies between the 2 subgroups of migraineurs, that is, those with and without the incorrect diagnosis of "cervical arthrosis." METHODS: Patients, between 18 and 65 years, were consecutively referred to 5 Headache Centers in 2 Italian regions for a first visit. They fulfilled the diagnostic criteria for migraine (with/without aura, episodic/chronic) and were enrolled in this cross-sectional study. Each patient underwent a specific cranial/cervical musculoskeletal clinical examination. RESULTS: A total of 117/250 subjects (46.8%) were unaware that they suffered from migraine. In these unaware subjects, the most frequently reported diagnosis was "cervical arthrosis" in 34/117 (29.1%), followed by tension-type headache in 23/117 (19%). The cervical region was the most common site of pain onset in the so-called "cervical arthrosis" group (52.9%, P < .0001), where also more pericranial (58.8%; P = .041) and neck (70.6%; P = .009) muscle tenderness, restricted range of cervical vertical (47.1%; P < .001), and lateral (29.4%; P = .040) movements were reported. More "cervical arthrosis patients" had been referred to an Emergency Department (88.2%; P = .011) and had undergone more cervical spine radiography (23.5%; P = .003) and magnetic resonance imaging (20.6%; P = .044). While they had used fewer triptans (11.8%; P = .007) and received less pharmacological prophylaxis (2.9%; P = .004). CONCLUSIONS: In our sample, there were high misdiagnosis rates for migraine sufferers in Italy. The most common misdiagnosis, that is, "cervical arthrosis," led to misuse of healthcare facilities and had a negative impact on the migraine treatment.

Prevalence of Neuropathic Pain in Patients with Traumatic Brachial Plexus Injury: A Multicenter Prospective Hospital-Based Study.

OBJECTIVE: Prevalence and clinical characteristics of neuropathic pain due to traumatic brachial plexus injury. DESIGN: Observational epidemiological study. SETTING: Hospital-based multicenter study. SUBJECTS: One hundred seven prospectively enrolled patients with brachial plexus injury. METHODS: All the patients underwent clinical examination and neurophysiological testing for a definitive diagnosis of the brachial plexus lesion. The DN4 questionnaire was used to identify neuropathic pain, and the Neuropathic Pain Symptom Inventory (NPSI) to evaluate the different symptoms of neuropathic pain. The SF36 questionnaire and the Beck Depression Inventory (BDI) were used to assess quality of life and mood disturbances in patients with neuropathic pain. RESULTS: Of the 107 enrolled patients, 74 had pain (69%); neuropathic pain, as assessed by means of the DN4, was identified in 60 (56%) of these patients. According to the NPSI, the most frequent and severe pain type was the spontaneous burning pain. Clinical and neurophysiological findings showed that pain is unrelated to age but is associated with the severity of peripheral nerve damage. The SF36 questionnaire and BDI showed that neuropathic pain impairs quality of life and causes depression. CONCLUSIONS: Our study provides information on the prevalence, characteristics, and variables associated with neuropathic pain due to traumatic brachial plexus injuries that might provide a basis for improving the clinical management of this condition.

Mind the Metabolic Gap: Bridging Migraine and Alzheimer's disease through Brain Insulin Resistance.

Brain insulin resistance has recently been described as a metabolic abnormality of brain glucose homeostasis that has been proven to downregulate insulin receptors, both in astrocytes and neurons, triggering a reduction in glucose uptake and glycogen synthesis. This condition may generate a mismatch between brain's energy reserve and expenditure, mainly during high metabolic demand, which could be involved in the chronification of migraine and, in the long run, at least in certain subsets of patients, in the prodromic phase of Alzheimer's disease, along a putative metabolic physiopathological continuum. Indeed, the persistent disruption of glucose homeostasis and energy supply to neurons may eventually impair protein folding, an energy-requiring process, promoting pathological changes in Alzheimer's disease, such as amyloid-ß deposition and tau hyperphosphorylation. Hopefully, the "neuroenergetic hypothesis" presented herein will provide further insight on there being a conceivable metabolic bridge between chronic migraine and Alzheimer's disease, elucidating novel potential targets for the prophylactic treatment of both diseases.

Breakthrough COVID-19 in people with multiple sclerosis on disease modifying treatments: Is it still a severe disease?

INTRODUCTION: Disease modifying treatments (DMTs) for multiple sclerosis (MS) are effective in preventing both relapses and disability progression. Highly effective treatments (HETs) are more effective than platform therapy in preventing confirmed disability progression (CDP), when used early. Infections may complicate HETs administration, and their prevention through vaccination is crucial in order to assure the safety of people with MS (pwMS). The aim of the present study is to describe the effect of MS DMTs on COVID-19 vaccination and the risk of breakthrough infection in a cohort of pwMS. MATERIALS AND METHODS: This is a monocentric retrospective observational study conducted at the MS center of the Guglielmo da Saliceto Hospital in Piacenza, Italy. One hundred and fifty-seven (157) pwMS who received two doses of the SARS-CoV-2 vaccine (with 80.3 % receiving a booster dose) were included in the study. RESULTS: fifty-six pwMS (35.7 %) were females, the mean age was 48.6 (SD: 12.87) years, and 59 (37.6 %) had at least one comorbidity. Twenty-five (15.9 %) breakthrough infections were observed, with 17 (68.0 %) classified as mild and 8 (32.0 %) as moderate. A multivariable linear regression model confirmed that B-cell suppressor DMTs and EDSS were factors associated with the latest antibody titre. Patients treated with B-cell suppressors exhibited a risk almost four times higher for breakthrough infections compared to other patients, with a hazard ratio (HR) of 3.72 (95 % CI: 1.50 - 9.27) (p = 0.005). CONCLUSIONS: B-cell suppressor DMTs are associated with the risk of breakthrough COVID-19 in our cohort, but vaccination fully protected pwMS against severe breakthrough disease.

Alexithymia Increases Pericranial and Cervical Muscle Tenderness in Women with Migraine.

Background/Objectives: Alexithymia is characterized by a deficit in identifying and communicating feelings. Emerging evidence suggests that alexithymia is highly prevalent in migraine, in a complex interplay with psychiatric comorbidity. Pericranial/cervical muscle tenderness is a remarkable clinical feature in a large proportion of migraine patients. This pilot study aimed at investigating the relationship between alexithymia and pericranial/cervical muscle tenderness in female migraineurs. Methods: A total of 42 female patients fulfilling the diagnostic criteria for migraine were enrolled into this pilot, observational, cross-sectional study after informed consent was obtained. Each patient underwent a psychological assessment to identify any alexithymia by means of TAS-20, anxiety/mood comorbidity (by means of STAI-Y1 STAI-Y2, BDI-II), and migraine-related disability (by means of HIT-6), and a physical cranial/cervical musculoskeletal examination. Palpation of pericranial and cervical muscles was carried out in the standardized manner. A Cumulative Muscle Tenderness (CUM) score (0-6) was calculated for each patient. A multivariate analysis was performed to investigate any association amongst the TAS-20 score, the CUM score, and the following covariates: BDI-II, STAI-Y1, STAI-Y2, and HIT-6 scores, age, disease duration, monthly migraine days, and average head pain intensity in the previous three months. Results: Overall, 35.6% of the sample had alexithymia. The multivariate analysis detected a linear and independent relationship between the TAS-20 and CUM scores, with a statistically significant (p = 0.017) association. Conclusions: This pilot study suggests that alexithymia plays a role in increasing pericranial/cervical muscle tenderness in migraine, independently from psychiatric comorbidity. A novel therapeutical approach, targeting alexithymia, may well reduce muscular tenderness in female migraineurs.

Direct Oral Anticoagulants and Concomitant Anti-seizure Medications: A Retrospective, Case-Control Study in a Real-World Setting.

PURPOSE: Although prescription of direct oral anticoagulants (DOACs) for epileptic patients on anti-seizure medications (ASMs) is on the increase, international guidelines pose strict restrictions because this may lead to pharmacologic interactions. However, current evidence on their clinical relevance remains scanty. This retrospective, case-control study assessed the frequency of ischemic/hemorrhagic events and epileptic seizures involving DOAC-ASM cotherapy in the real world, compared with DOAC and ASM monotherapy, in age- and gender-matched controls. METHODS: Data on patients who had been prescribed a concomitant DOAC and ASM therapy for at least 6 months were extracted from the database of the Pharmaceutical Service of the Alessandria Province (Italy). After exclusions, the case group included 124 patients, 44 on valproic acid (VPA) and 80 on levetiracetam (LEV) concomitant with a DOAC, and it was compared with the DOAC-control and ASM-control groups. The clinical and laboratory data were extracted from the electronic archives of the hospitals in the same province. FINDINGS: Two (1.6%) ischemic and 2 (1.6%) major hemorrhagic events were observed in the case group. Four (3.2%) ischemic and no hemorrhagic events occurred in the DOAC-control group. There were no statistically significant differences in the ischemic and hemorrhagic events between the case group (patients on concomitant LEV or VPA who were prescribed a DOAC) and the DOAC-control group, and there was no difference in the recurrence rate of epileptic seizures between the case group and the ASM-control group. IMPLICATIONS: Although this study has some limits, mainly the small sample size, our findings indicate that neither LEV nor VPA concomitant treatment significantly affects the effects of DOACs in a real-world setting.

Brainstem activation in cluster headache: an adaptive behavioural response?

INTRODUCTION: The functional neuroimaging of headache patients has revolutionized our understanding of the pathophysiology of primary headaches, providing unique insights into these syndromes. Indeed, functional neuroimaging studies have shown the activation of specific brain structures, the brainstem in migraine and posterior hypothalamus in cluster headache (CH), as well as in other trigeminal autonomic cephalalgias. We describe the functional neuroimaging findings in a patient suffering from CH headache, investigated with functional magnetic resonance imaging (fMRI) during typical pain attacks. MATERIAL AND METHODS: Two typical, consecutive CH attacks were investigated by two fMRI imaging sessions on the same day. Both fMRI scans were performed at rest, during the CH attacks and the pain-free state induced by subcutaneous administration of sumatriptan. RESULTS: Significant activation of the bilateral red nucleus, ventral pons and trigeminal root entry zone ipsilaterally to the pain side was detected during the pain state, in addition to the hypothalamic region ipsilaterally to the pain side. CONCLUSION: Being that such structures are mainly involved in motor function and reactive behaviour, their activation, in our hypothesis, may be linked to pain avoidance and may well represent a defence reaction in cluster headache, which is characterised by a "fight-or-flight" type behavioural pattern during pain attacks.
