Aspiration Risk Screening With Tongue Pressure Measurement in Acute Stroke: A Diagnostic Accuracy Study Using STARD Guidelines.

Introduction: Dysphagia can affect more than 50% of stroke patients in the acute phase. Aspiration pneumonia is a serious complication that can be prevented with dysphagia screening and assessment. Measurement of tongue elevation pressure is suggested to be a useful tool in aspiration risk screening. Objective: This study aimed to assess the diagnostic accuracy of maximum anterior tongue elevation strength (Pmax) in acute stroke care. Method: In this prospective study, data were collected in a neurology department (stroke center) where patients formed a consecutive case series. The sample consisted of thirty stroke patients who failed an initial dysphagia screening. Patients underwent anterior tongue elevation strength measurement (index test) during bedside dysphagia assessment by a speech-language pathologist and flexible endoscopic evaluation of swallowing (reference test) by an otorhinolaryngologist on the same day. Outcome variables (index values in kPa, reference values interpreted on the penetration-aspiration scale) were used for estimating measures of diagnostic accuracy in aspiration risk screening. Results: Ten patients aspirated on instrumental evaluation. At the cut-off point of ≤ 34 kPa the analysis showed 90% sensitivity, 35% specificity, 41% positive predictive value, and 88% negative predictive value. The area under the curve (AUC) for Pmax was AUC = 0.700 (95% CI [0.500-0.900]). Conclusion: Although individuals with low anterior tongue elevation strength tend to have a higher risk of aspiration, this variable alone is not capable of screening aspiration in acute stroke. In combination with a thorough noninstrumental bedside examination, it might have the potential to reduce the number of false positive cases. Further studies in this area would be worthwhile.

Successful thrombolytic therapy is associated with increased granulocyte CD15 expression and reduced stroke-induced immunosuppression.

OBJECTIVES: Stroke-induced immunosuppression (SIIS) increases the risk of poststroke infections. We aimed to determine whether failed versus successful thrombolytic therapy (TT) resulted in SIIS-associated changes in peripheral granulocyte markers at 1 week following the insult. METHODS: We collected peripheral blood samples from 19 patients with acute ischemic stroke undergoing TT within 6 h after the onset of their first symptoms and 7 days after the insult. Age-matched controls were sampled on one occasion. We compared the expression of CD15 and CD64 on monocytes, granulocytes, and lymphocytes using flow cytometry. RESULTS: The proportion of granulocytes and CD15+ granulocytes was comparable between controls and stroke patients at both time points. While the proportion of CD15bright granulocytes was also comparable, the mean fluorescence intensity (MFI) of CD15 on this subset was reduced in stroke patients by day 7 but was overall higher at both time points compared to controls. The MFI of CD15 on granulocytes was lower in stroke patients with failed TT than in those with successful TT 1 week after the insult. CONCLUSIONS: Our current results indicate that TT may not only acutely reduce the systemic inflammatory response following stroke but may also play a role in reversing SIIS at a later stage following the insult, as reflected by the higher expression of the CD15 marker on granulocytes following successful TT.

Hungarian adaptation of an international swallowing screening method / Egy nemzetközi nyelészavarszurési módszer hazai adaptálása

Introduction: Swallowing disorders caused by stroke can affect half of the cases in the acute phase. The guidelines for nutrition therapy for stroke patients recommend several screening methods for swallowing disorders. The Gugging Swallowing Screen (GUSS) is one of the most widely used ones but has not been available in Hungarian until now. Objective: Adaptation and validation of the GUSS to Hungarian in acute stroke patients (GUSS-H). Method: Our research design was two-phased: for the adaptation, a five-step protocol was composed according to international guidelines. The second phase was the validation of the GUSS-H. For external validity, data from patients (n = 31) were compared to the reference values of the fiberoptic endoscopic evaluation of swallowing (FEES) for both dysphagia and aspiration risk. Internal validity was obtained by comparing data from two independent evaluators (n = 20). Results: According to the FEES results, dysphagia prevalence was 45%, aspiration prevalence was 32.3% in our sample. Inter-rater reliability was strong on both GUSS-H scores and severity of dysphagia (𝜅 = 0.899, p<0.001; 𝜅 = 0.801, p<0.001). The diagnostic accuracy of the test showed great results for both the risk of dysphagia and aspiration (sensitivity: 93%, 90%; specificity: 65%, 57%; positive predictive value: 68%, 50%; negative predictive value: 92%, 92%). Discussion: Compared to the original GUSS and other bedside screenings, GUSS-H performed better than average in terms of sensitivity and negative predictive value. It could predict the risk of dysphagia and aspiration, make recommendations for instrumental evaluation and dysphagia diet. Conclusion: Swallowing screening is one of the first steps of nutritional therapy for acute stroke patients which needs an interdisciplinary setting. With our study, GUSS-H is now available to Hungarian professionals.

Medical nutrition therapy of stroke patients with dysphagia ­ 2021 / A dysphagia táplálásterápiája stroke-betegek esetében - 2021.

Összefoglaló. A neurológiai betegek körében a dysphagia elofordulása gyakori, és több oka van. Az utóbbi évek kutatásai a közvetlen neurológiai kórokok (beleértve a gyakori stroke) szerepét is részletesen feltárták. Felismerték az ún. néma aspiráció jelentoségét: ez gyakran áll az (aspirációs) pneumonia hátterében, amely sokszor halálos szövodmény lehet. Az ún. poststroke pneumonia fogalma gyökeresen más értelmezésbe helyezte a stroke-ot követo tüdogyulladások megítélését, jellegzetessége alapján egyértelmuen a stroke közvetlen cerebralis hatásaként alakul ki. Egyértelmuvé vált a nyelészavar korai felismerésének és ellátásának szükségessége. A stroke-betegek megfelelo tápláltsági állapota az eredményes rehabilitációnak, a szövodményszám csökkentésének, a rövidebb kórházi kezelésnek, az alacsonyabb mortalitásnak a záloga. A dysphagia a betegség kimenetelének független elorejelzoje lehet, különösen az elso három hónapban. A nyelészavar malnutritióval, kiszáradással és a kórházi tartózkodás hosszabb idotartamával jár együtt, emeli a gyógyszerköltségeket. A stroke-beteg ellátásának egyik elso eleme a dysphagia szurése. Táplálásterápiára akkor szorul a stroke-beteg, amikor magas a kóros tápláltsági állapot kialakulásának kockázata, és per os táplálással nem fedezheto biztonságosan a megfelelo energia-, tápanyag- és folyadékbevitel. A táplálásterápia módját, eszközeit, az energia- és tápanyagbeviteli célértékeket az orvos határozza meg, az alapbetegség súlyosságától, a társbetegségektol és a laborértékektol függoen. Az étrend minden esetben individuális és progresszív, azaz alkalmazkodik a beteg állapotához és annak változásához. A dietetikus feladata a megfelelo diéta összeállítása mellett a beteg, a hozzátartozó és a kezeloszemélyzet oktatása, az állapot követése, a beteg tápláltsági állapotának, tápanyagbeviteli értékeinek gyakori elemzése, szükség esetén tápszerek ajánlása. Orv Hetil. 2021; 162(40): 1601-1609. Summary. Among neurological patients, the incidence of dysphagia is common and has several causes. Research in recent years has explored the role of direct neurological pathogens (including frequent strokes). The frequency of 'silent aspiration', which often underlies (aspirational) pneumonia and can be a fatal complication, has been recently discovered. The concept of 'post-stroke pneumonia' has drastically changed the assessment of post-stroke pneumonia. Based on its characteristics, it clearly develops as a direct cerebral effect of stroke. The need for early detection and early care of swallowing disorder has become clear. Adequate nutritional status of stroke patients is the key to successful rehabilitation, reduction of complications, shorter hospitalization, and lower mortality. Dysphagia can be an independent predictor of disease outcome, especially in the first three months. Swallowing disorder is associated with malnutrition, dehydration and longer lengths of hospital stay, increasing drug costs. One of the first elements in the care of a stroke patient is screening for dysphagia. The stroke patient needs nutritional therapy when the risk for abnormal nutritional condition is high or if the condition is already present, or when oral nutrition does not safely cover adequate energy, nutrient and fluid intake. The method and means of nutritional therapy, the goals of energy and nutrient intake are determined by the doctor, depending on the severity of the underlying disease, comorbidities and laboratory values.The diet is individual and progressive in each case. The dietitian's task is not only to compile a proper diet, but also to educate the patients and relatives. The dietitian is responsible for monitoring the patient's nutritional status.

Simultaneous subdural, subarachnoideal and intracerebral haemorrhage after rupture of a peripheral middle cerebral artery aneurysm.

The cause of intracerebral, subarachnoid and subdural haemorrhage is different, and the simultaneous appearance in the same case is extremely rare. We describe the case of a patient with a ruptured aneurysm on the distal segment of the middle cerebral artery, with a concomitant subdural and intracerebral haemorrhage, and a subsequent secondary brainstem (Duret) haemorrhage. The 59-year-old woman had hypertension and diabetes in her medical history. She experienced anomic aphasia and left-sided headache starting one day before admission. She had no trauma. A few minutes after admission she suddenly became comatose, her breathing became superficial. Non-contrast CT revealed left sided fronto-parietal subdural and subarachnoid and intracerebral haemorrhage, and bleeding was also observed in the right pontine region. The patient had leucocytosis and hyperglycemia but normal hemostasis. After the subdural haemorrhage had been evacuated, the patient was transferred to intensive care unit. Sepsis developed. Echocardiography did not detect endocarditis. Neurological status, vigilance gradually improved. The rehabilitation process was interrupted by epileptic status. Control CT and CT angiography proved an aneurysm in the peripheral part of the left middle cerebral artery, which was later clipped. Histolo-gical examination excluded mycotic etiology of the aneu-rysm and "normal aneurysm wall" was described. The brain stem haemorrhage - Duret bleeding - was presumably caused by a sudden increase in intracranial pressure due to the supratentorial space occupying process and consequential trans-tentorial herniation. This case is a rarity, as the patient not only survived, but lives an active life with some residual symptoms.

Population-based stroke screening days in the 12th district of Budapest in 2011 and 2016 - What have and what have not changed?

BACKGROUND AND PURPOSE: Population-based screening is an option to identify persons at high risk for stroke. However it is associated with rather high expenses, necessitating the selection of effective methods that take local characteristics into account. The 12th district of Budapest has a long tradition of population-based screening for frequent and preventable diseases. The Szent János Hospital hosts an annual stroke screening day. In the present study, previously published data from the 2011 screening were compared with those obtained in 2016, looking for changes and tendencies throughout the examined period. METHODS: The screening day was conducted in a generally similar way in 2011 and 2016. Similarly to the previous event, the program was organized on a Saturday, the call for the event was spread by the local newspaper. The crew composition was the same. As regards the components of the screening (currently including general history taking, risk status assessment, blood pressure measurement, BMI assessment, cholesterol and blood glucose tests, carotid duplex ultrasonography, and ophthalmological examination), the only difference was the absence of cardiologic examination (it was conducted on an independent day). The anonymous data sheet was the same. RESULTS: The number of participants in the 2016 event was 33, to provide more comfortable conditions. The female predominance was slightly less pronounced but was still present in 2016 (60.6% vs. 72.9%). The mean age became substantially higher (71.2 y vs. 62.9 y). The ratios of participants with higher level of education (97% vs. 94%) and those who are married were still remarkable. The most frequent risk factors were the same; however the ratio of participants with hypertension, 'other heart disease', and diabetes increased, whereas that of with hyperlipidemia and obesity decreased. The incidence of atrial fibrillation was unaltered. None of the participants in 2016 admitted smoking (previously this ratio was 20.8%) or drinking heavily. The findings of the carotid ultrasonography revealed a more favorable vascular status. Ophthalmological assessments (predominantly hypertensive alterations on fundoscopy) revealed that the pathological vs. physiological ratio switched to 1:2 from 2:1. The final evaluation of the screening program likewise demonstrated an improved overall state of health of the population. CONCLUSION: We observed a more favorable stroke risk status of the population in 2016. Whether it is indeed a tendency unknown at present. The role of the local media in calling for screening is still decisive, and the cohesive power of the family is important.

[Chocolate consumption and Hungarian Nobel laureates]. / Csokoládéfogyasztás és a magyar Nobel-díjasok.

INTRODUCTION: Certain dietary items contain significant amounts of flavonoids which was shown to improve cognitive function. An earlier investigation demonstrated a strong linear correlation between chocolate consumption and the number of Nobel laureates in a given country. However, Hungary and the Hungarian Nobel laureates were not included in this analysis. AIM: In this publication, we aim to complement these data by analyzing data available for Hungary. METHOD: The number of Nobel laureates per country and the international data on chocolate consumption were based on the previously published results. The amount of chocolate consumption in Hungary was based on data from the Hungarian Central Statistical Office. GDP per capita and Research and Development Expenditure data for the investigated countries were derived from the World Bank. RESULTS: There are 11 Nobel laureates from Hungary. Based on this, Hungary ranks the 9th amongst the 24 studied countries. However, it only ranks the 19th when it comes to chocolate consumption. Correlations were found between the number of Nobel laureates and GDP per capita (r = 0.734; p = 0.001) as well as Research and Development Expenditure (r = 0.532; p = 0.01) amongst the studied countries. CONCLUSION: The achievements of Hungarian scholars do not support the earlier notion that there is a link between the number of Nobel laureates (cognitive function) and the chocolate consumption in a given country. Their biographies highlight the importance and more possibilities of research funding in wealthier countries. Orv Hetil. 2019; 160(1): 26-29.

A case report of isolated distal upper extremity weakness due to cerebral metastasis involving the hand knob area.

BACKGROUND: Unilateral weakness of an upper extremity is most frequently caused by traumatic nerve injury or compression neuropathy. In rare cases, lesion of the central nervous system may result in syndromes suggesting peripheral nerve damage by the initial examination. Pseudoperipheral hand palsy is the best known of these, most frequently caused by a small lesion in the contralateral motor cortex of the brain. The 'hand knob' area refers to a circumscribed region in the precentral gyrus of the posterior frontal lobe, the lesion of which leads to isolated weakness of the upper extremity mimicking peripheral nerve damage. The etiology of this rare syndrome is almost exclusively related to an embolic infarction. CASE PRESENTATION: We present the case of a 70-year-old male patient with isolated left sided upper extremity weakness and clumsiness without sensory disturbance suggesting a lesion of the radial nerve. Nerve conduction studies had normal results excluding peripheral nerve damage. Neuroimaging (cranial CT and MRI) detected 3 space occupying lesions, one of them in the right precentral gyrus. An irregularly shaped tumor was found by CT in the left lung with multiple associated lymph node conglomerates. The metastasis from this mucinous tubular adenocarcinoma with solid anaplastic parts to the 'hand knob' area was responsible for the first clinical sign related to the pulmonary malignancy. CONCLUSIONS: Pseudoperipheral palsy of the upper extremity is not necessarily the consequence of an embolic stroke. If nerve conduction studies have normal results, neuroimaging - preferably MRI - should be performed, as lesion in the hand-knob area of the precentral gyrus can also be caused by a malignancy.

Assessment of the Efficiency of Stroke Awareness Campaigns in Hungary.

BACKGROUND: The critical period of stroke management lies between the disease onset and the time of the emergency call, relying on stroke-related knowledge of the population. Public campaigns play a role in spreading relevant health information. Due to the substantial expenses of these campaigns, the assessment of their efficiency is reasonable. METHODS: We assessed the number of thrombolytic treatments performed in Hungary, subjected to national media coverage and in particular in Budapest, being the location of the Stroke Day campaign, in the period between 2008 and 2015. We compared the change in the daily mean number of thrombolytic treatments performed during the preceding and following day, week, and month. Data were also compared with annual means. RESULTS: No meaningful changes can be seen in the number of thrombolytic treatments on the days immediately following Stroke Days, and casual differences can be seen in the following week. The comparison of the numbers of thrombolytic treatments performed in the postcampaign months with the monthly means in the corresponding years revealed a positive effect in each year except for 2012, 2014, and 2015. Regarding the whole examined period, however, the effect is not statistically significant, neither for data obtained from Hungary nor from Budapest. CONCLUSIONS: Better outcomes were observed 1 month after a campaign than more immediately. This can be partly explained by ongoing media coverage in a given period rather than exposure of the public on a single Stroke Day.
