Advantage and use of S-patch cardio solution in competitive motor sports
Authors: Puhr-Westerheide D. , Kostbade T. , Clevert D.-A. 
Published: November 2019

BACKGROUND: Motorsport karting has developed into a professional international competition. Kart racing poses a unique set of physiologic challenges for athletes who compete in this sport. Until today no major study has evaluated the physical and cardiac challenge in professional kart racing. OBJECTIVE: The aim for this study was to measure and analyze heart rate and cardiac rhythm by a mobile, smartphone based ECG (s-patch) on professional kart-race-drivers during actual karting races through annual seasons to test the hypotheses that high g-force and stress could trigger cardiac arrhythmia. MATERIAL AND METHODS: ECG-data from kart-drivers were acquired during local races, the ADAC Kart-Masters (KZ2), the German Kart Championship (DSKC) and the European Championship Senior CIK-FIA-Serie and analyzed in this observational study. In total, free practice, qualifying practice and 32 races were assessed during the kart season 2019. Data were interpreted by two independent experienced physicians. RESULTS: The average heart rate (HR) during a selected German Kart Championship (DSKC) race in Genk (Belgium) was 169 beats min-1. The longest R-R interval was 0.72 sec. The average HR during a selected European Championship CIK-FIA-race in Lonato (Italy) was 160 beats min-1. The longest R-R interval was 0.74 sec. The average HR during a selected ADAC Kart-Masters (KZ2) races in Wackersdorf (Germany) was 147 beats min-1. The longest R-R interval was 0.86 sec. In total 32 races could be recorded successful. No couplets or bigeminy cycles were detected. In one other kart racer a supraventricular extrasystole and a ventricular extrasystole was detected. Interestingly, kart-drivers were found to have sinustachycardia throughout the races most likely triggered by emotional and physiological stress during speeding. CONCLUSION: Professional kart racing drivers had sinustachycardia with heart rates up to 193 beats min-1 during races. This is most likely attributed to a considerably high emotional and physiological stress affecting the cardiovascular system. Episodes of tachycardia positively correlated with mean speed. In the warm-up lap the heart rate was significantly lower in comparison to the race, suggesting that faster driving speed would induce greater cardiovascular stress to professional drivers during actual races. The experimental results showed that the proposed S-patch system provided a good ECG signal quality with accurate measurements even during the kart race and could detect the ECG features of the race in real time. The cardiac interpretation software performs well and is a useful tool to assist clinicians.

Background: Neuropsychiatric symptoms (NPS) occur frequently in the course of Alzheimer’s disease (AD) and are suspected to be associated with a faster dementia progression. Numerous reports have defined specific subsyndromes, summarized in clusters of items of the Neuropsychiatric Inventory (NPI). Objective: This study investigated the influence of specific NPI subsyndromes and clinical patient characteristics on dementia progression. Methods: Data of the prospective registry on dementia in Austria (PRODEM) were retrospectively analyzed. Cognitive functioning was determined at baseline and 2 yearly follow-up visits using the Mini-Mental State Examination (MMSE) and the Consortium to Establish a Registry for Alzheimer’s dementia neuropsychological test battery (CERAD). To assess NPS, the NPI was used: NPI items were classified in three subsyndromes (psychotic cluster, behavioral cluster, emotional cluster). Results: Out of the 662 included patients (mean age 76.4±8.4 years), 43% completed follow-up visits for two years. Significant correlation between higher scores in all three subsyndromes and worse cognitive performance were found for MMSE score, naming, and verbal fluency. Results of linear mixed model analysis revealed lower age and higher scores in the psychotic cluster as significant predictors of changes in MMSE with time. Conclusion: In this study, we report the influence of psychotic subsyndromes and lower age on faster MMSE decline in early AD. These results emphasize the importance of not only assessing but also differentiating neuropsychiatric symptoms in subsyndromes in the early stages of AD as a possible predictor of disease progression.

Published: November 2019

BACKGROUND: We aimed to investigate whether the change in methemoglobin levels (ΔMHb) predicts oxygenation response to inhaled nitric oxide (iNO) in persistent pulmonary hypertension of the newborn (PPHN) with lung disease, with or without pulmonary hypoplasia. METHODS: In this prospective observational study, infants were categorized based on ΔMHb and oxygenation response (ΔPaO2/FiO2) following iNO: ΔMHb ≤0 or ΔMHb>0, and ΔPaO2/FiO2 < 20 mmHg (Non-responder) or≥20 mmHg (Responder). ΔMHb levels were compared among infants with or without pulmonary hypoplasia. RESULTS: Among infants with pulmonary hypoplasia ( n = 28), ΔMHb was not associated with an oxygenation response to iNO or survival without ECMO. Among infants without hypoplasia ( n = 29), subjects with ΔMHb>0 following iNO ( n = 21) had a greater ΔPaO2/FiO2 (median, 64 mmHg; IQR, 127; p < 0.01) and 100% survival without extracorporeal membrane oxygenation (ECMO) when compared to infants with ΔMHb ≤0 ( n = 8; median 10 mmHg; IQR, 33). CONCLUSIONS: PPHN secondary to lung disease without hypoplasia with increased ΔMHb following iNO was associated with better oxygenation response and survival without ECMO compared to subjects without an increase in MHb.

BACKGROUND: Chronic hypothalamic-pituitary-adrenal (HPA) axis activity role in the pathogenesis of preterm birth (PTB) remains unclear due to inconsistent measures with limited ability to monitor long-term cortisol concentrations. We explored this relationship using the novel method of assessing cortisol in hair, which is a valid and reliable measure of chronic HPA axis activity. METHODS: 137 participants (40 PTB cases and 97 controls from a birth cohort of pregnant women in Peru) were interviewed and invited to provide a 9-cm hair sample from the posterior vertex position of the scalp (mean = 13 weeks gestation). Hair cortisol concentration (HCC) was determined using luminescence immunoassay and values were natural-log transformed. PTB cases were defined as women who delivered before 37 gestational weeks. Case-control differences were assessed using multivariable linear and logistic regressions. RESULTS: Overall, combined pre-conception and first-trimester HCC was 13% lower among cases as compared with controls ( p-value = 0.01). Compared with controls, maternal HCC among PTB cases were 14% ( p = 0.11), 10% ( p = 0.22) and 14% ( p = 0.08) lower for 3–6 months pre-conception, 0–3 months pre-conception, and first trimester, respectively. After adjusting for putative confounders, a 1-unit increase in HCC was associated with 55% reduced odds of PTB (aOR = 0.45; 95% CI: 0.17–1.17). For a 1-unit increase in HCC in the scalp-intermediate and scalp-distal segments (representing HCC concentrations in 0–3 months pre-conception and first trimester), the corresponding odds for PTB were 0.53 (95% CI: 0.19–1.48) and 0.39 (95% CI: 0.13–1.13), respectively. CONCLUSIONS: Women who deliver preterm, as compared with those who deliver at term, have lower preconception and first trimester HCC. Our findings suggest that HPA axis activation, integral to the adaptive stress-response system, may be chronically dysregulated in women at increased risk of PTB.

BACKGROUND: Respiratory support in the form of mechanical ventilation is a crucial intervention in premature neonates, with respiratory problems. However, prolonged mechanical ventilation and endotracheal intubation may be associated with major adverse effects. The ideal time for extubation is based on clinical and laboratory parameters assessed at the time of planned extubation. However, such parameters are not very objective, which makes extubation in NICUs a trial-and-error approach. OBJECTIVE: This work was done to assess the use of extubation bundle including modified spontaneous breathing trial (SBT) (10 minutes) to reduce the rate of reintubation, among preterm neonates≤30 weeks who were mechanically ventilated and extubated to non-invasive ventilation in the NICU, Women’s Wellness and Research Center (WWRC), Hamad Medical Corporation (HMC), Doha, Qatar. METHODS: A prospective study based on the collection of data regarding preterm neonates≤30 weeks gestation admitted to the NICU, Women’s Wellness and Research Center (WWRC), from January, 2015 to December, 2017, who were subjected to mechanical ventilation (MV) and extubation. When the clinical team decides a newborn is ready for extubation based on the extubation bundle, a modified SBT (10 min) is used. RESULTS: This study included 465 premature babies from 24-≤30 weeks recruited in the NICU, Women’s Wellness and Research Center (WWRC). Extubation bundle with modified SBT was able to predict success of extubation with 95% sensitivity and 90.4% Positive Predictive Value (PPV) in the gestational age (GA) group 24 -≤27 weeks (245) and 95.3% sensitivity and 90% PPV in the GA group > 27 -≤30 weeks (220). As expected, successfully extubated babies had a higher GA and weighed more at extubation, compared to babies who required re-intubation. CONCLUSION: We recommend the extubation bundle with modified SBT prior to elective extubation to be used in predicting successful extubation in premature babies. Guidelines for extubation among premature babies are needed in order to reduce unnecessary exposure to adverse effects of mechanical ventilation.

We have discovered that the molecular weight of surfactant polyvinylpyrrolidone (PVP) used in the hydrothermal step, as well as the temperature for phosphorization, played very important roles in determining the electrochemical properties of the samples. Specifically, the sample synthesized using PVP with 10 k molecular weight and phosphorized at 300°C demonstrated the best supercapacitive performance among the different samples, with the highest capacitance and most stable cyclic retention. When an asymmetric supercapacitor (ASC) was assembled with this Ni

Yeşeya:58 Bağlamında Yahudilik, Hristiyanlık ve İslam’da Makbul Orucun Anlamı
Authors: DÖLEK İlbey 
Published: November 2019

Makbul orucu, Tanrı’nın
kullarından istediği ve bundan hoşnut olacağı gerçek ya da doğru oruç olarak
tarif etmek mümkündür. Bakara suresi 183. ayette geçen “oruç size farz
kılındığı gibi sizden öncekilere de farz kılınmıştır” ifadesinden hareketle
İslam’dan önce Yahudileri ve Hristiyanları içine alan diğer din mensupları için
de oruç tutmanın emredildiği anlaşılmaktadır. Bu makale, Kuran’ın dışında
Yahudi ve Hristiyan kutsal metinlerinde oruç nasıl anlatılmaktadır? Söz konusu
dinlerin kutsal metinlerinde makbul oruç tasvirleri arasında ne tür benzerlik
ve farklar bulunmaktadır? Tanah’ın Yeşaya Kitabı, 58. bölümündeki “Gerçek
Oruç” bağlamında oruç ibadetinin özünde ne vardır? ve Rab’bin hoşnut
olacağı makbul orucun fenomenolojik anlamda özellikleri nelerdir? sorularına
odaklanmaktadır. Kadim bir geçmişi olan
oruç ibadetinin gizli ve gösterişten uzak yapılması kutsal metinlerin ortak
tavsiyesidir. Bunun yanında hem insanın
kendi nefsini terbiye etmede bir araç hem de Tanrı ile olan ilişkisinde
yakınlaşmayı sağlayan bir ibadet olarak orucun, Tanrı katında makbul bir değere
sahip olması için ahkâmı yanında adabının ve esrarının (hikmet) da gözetilmesi
gerektiği kutsal metinlerde ifade edilmektedir.

Amalgamation to gold in artisanal small scale generally uses mercury (Hg) that decrease the quality of environment especially water. A study of mercury artisanal small scale gold mine waste water was conducted by utilizing simple technology using Sub Surface Flow - Constructed Wetland (SSF-CW) system. This system is a combination of phytoremediation methods using Echinodorus palaefolius plant with zeolite as growth media. The purpose of this study was to determine the stability of SSF-CW in reducing Hg concentration in water. This SSF-CW system model has dimensions of 820 mm x 320 mm x 585 mm consisting of 3 zones, namely the inlet zone, the reaction zone and the outlet zone. The study was conducted with an initial HgCl2 waste concentration of 14.94 mg / L which was carried out in two stages, continuous and batch for 12 hours and lasted for 3 days for each stage. Effluent samples were taken every 0 hours, 4 hours, 8 hours, and 12 hours for mercury concentration analysis using Direct Mercury Analyzer (DMA). The result showed that SSF-CW could support the process of reducing Hg concentration n wastewater with removal efficiency of 98.99%. Echinodorus had the ability to accumulate metals with a BCF value of 9,117. and the accumulation of Hg in the zeolite (as growth media) was still far from the saturated capacity to absorb mercury
