Background and Purpose: Unilateral spatial neglect (USN) is often observed in ischemic stroke patients suffered their right parietal lobe. USN is an obstacle to undergo rehabilitation smoothly, then might influence the recovery of activities of daily living (ADL) after stroke. We aimed to clarify the association between the presence of USN after ischemic stroke and the ADL improvement. Methods: Consecutive patients with first-ever ischemic stroke and left limb paralysis who admitted to within 7 days from onset during February 2011 and March 2019 were included. Patients met the following criteria were excluded: mRS ≥3 before onset, NIHSS >15 on admission, without left limb paralysis, and missing NIHSS or functional independence measure (FIM) score on admission. Multiple regression analysis was performed to investigate the association between FIM efficiency score of acute phase and following factors: age, sex, acute reperfusion therapy (using an intravenous infusion of recombinant tissue plasminogen activator and/or endovascular therapy), FIM score on admission, and other clinical characteristics. All data were collected retrospectively using our electrical health record. Results: 721 ischemic stroke patients with left limb paralysis (320 women, median age 76) were included. Median FIM efficiency score was significantly lower in patients with USN than without USN (n=240, 481; 0.83 vs 1.63, respectively). Multiple regression analysis showed that USN, age, and acute reperfusion therapy were significant prognostic factors of FIM efficiency (coefficient and 95% confidence interval [CI]: -0.135 [-0.771 to -0.153], -0.106 [-0.022 to -0.002], and 0.224 [0.136 to 0.305], respectively). Conclusions: USN significantly influence the recovery of ADL after ischemic stroke. Clinicians should adequately evaluate USN after stroke and undergo USN-specific rehabilitation for them to optimize the effect of post-stroke rehabilitation. USN-specific rehabilitation might lead to better FIM efficiency.

Surgical Data

To evaluate surgeons’ performance, health care managers often use the revenues that surgeons make for the hospital. The purpose of this study is to determine the relationship between surgeons’ technical efficiency and their revenues by using multiple regression analysis on surgical data. The authors collected data from all the surgical procedures performed at University Hospital from April 1 through September 30 in 2013-2018. Output-oriented Charnes-Cooper-Rhodes model of data envelopment analysis was employed to calculate each surgeon’s technical efficiency. Seven independent variables were selected; revenue, experience, medical school, surgical volume, sex, academic rank, and surgical specialty. Multiple regression analysis using Tobit model was used for our data. The data from a total of 17 227 surgical cases were obtained in the 36-month study period. The authors performed multiple regression on 222 surgeons. Revenue had significantly positive association with mean efficiency score ( P = .000). Surgical volume had significantly negative association with mean efficiency score ( P = .000). The other coefficients were statistically insignificant. An increase in revenue by 1% was associated with 0.46% to 0.52% increases in efficiency score. We demonstrated that surgeons’ revenue can serve as a proxy variable for their technical efficiency.

The Relationship

The purpose of our study was to investigate the relationship between MRI/PWI-Time Intensity curve (TIC) and 3-month clinical outcome following endovascular reperfusion therapy in acute ischemic stroke patients with occlusion of the internal carotid artery (ICA) or the middle cerebral artery (MCA). We retrospectively analyzed the acute stroke patients 1) who were admitted to our institution from 2004 to 2010, 2) with serious neurological symptoms, 3) who had total occlusion of the ICA or MCA displayed by MRA with DWI -PWI mismatch and 5) who underwent emergency endovascular reperfusion therapy within 8 hours from stroke onset. We investigated patient's baseline characteristics, emergency MRI findings , successful recanalization defined as TICI 2B or 3,and 3-month modified Rankin scale(3M-mRS). We evaluated PWI findings using TIC types. Region of interests were set at symmetrical positions of the bilateral MCA territories and time-intensity-curves (TICs) were calculated. The types of TICs were classified into four patterns according to the timeto peak (TP) and the reduction value of the peak signal (PV). Comparing the affected side with the contralateral side, we defined type 1 as TPa>TPc and PVaTPc and PVc/2≤PVa<PVc, type 3 as TPa >TPc and PVa≥PVc, and type 4 as TPa=TPc. We analyzed the relationship between the PWI/TIC and mRS at 3 months (3M-mRS) statistically. We defined favorable clinical outcome as 3M-mRS of 0-2, and assessed pre-treatment predictors for favorable clinical outcome and death within 3months by using logistic regression analysis. Seventy one patients were analyzed. Their median age was 75 years, median admission NIHSS was 17, median DWI-ASPECT score was 7, sixty three patients had cadiogenic stroke, successful recanalization was achieved in 38 patients (54.0%), and median 3M-mRS was 3. Twenty three patients (32%) had 3M-mRS of 0-2 and 11 patients (37%) died within 3 months. PWI-TICs of type 1,2,3 and 4 were in 13, 37, 21 and 0 patients, respectively. Type of PWI-TIC was significantly correlated to 3M-mRS (r=-0.24,P=0.047). The higher PWI/TIC type were, the lower 3M-mRS were. Logistic regression analysis demonstrated that independent predictors of favorable clinical outcome (3M-mRS of 0-2) were DWI ASPECTS and age, whereas, independent predictors of death within 3months from onset were type 1 of PWI-TIC (OR,5.71;95%CI,1.28-25.4, P=0.022) and admission NIHSS. Conclusion; In ischemic stroke patients who underwent endovascular reperfusion therapy for the ICA or MCA occlusion within 8hours from onset, type of PWI-TIC was the significant predictor for death within 3months from onset.

Serum Fatty Acids

Introduction: There are few reports about the association of concentrations and proportions of serum fatty acids with age at the onset of acute ischemic stroke (AIS) in elderly patients. Hypothesis: A higher level of saturated FA (SFA) and n-6 polyunsaturated FA (PUFA) cause a younger onset of AIS, and a higher level of n-3 PUFA causes an older onset of AIS. Methods: For the retrospective cross-sectional study, we included patients aged 50 years or older who: 1) were admitted to our institution between August 2016 and July 2019 within 24 hours of AIS onset, and 2) underwent an examination of serum fatty acids. We evaluated concentrations of palmitic acid (PA) and stearic acid (SA) as SFA, oleic acid (OlA) as n-9 PUFA, linoleic acid (LiA), dihomo-gamma-linolenic acid (DGLA), arachidonic acid (AA) as n-6 PUFA on admission. We evaluated the concentration of alpha-linolenic acid (AlA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) as n-3 PUFA on admission. We evaluated the proportion of PA, SA, OlA, LiA, DGLA, AA, AlA, EPA, and DHA on admission. Furthermore, we evaluated their correlations with age at the AIS onset. Results: Three hundred sixty-six patients met our inclusion criteria. Their median average age was 75 years. Age at the onset was negatively correlated with concentrations of PA, SA, OlA, LiA, DGLA, AA, and AlA. Age at the onset was negatively correlated with the proportion of SA, OlA, and DGLA and positively correlated with the proportion of EPA and DHA. Multiple regression analysis showed that DGLA was an independent factor for the younger onset of AIS. Multiple regression analysis showed that DHA proportion was an independent factor for the older onset and that proportions of SA and DGLA were independent factors for the younger onset of AIS. Conclusions: The higher proportion of SA (SFA) and higher concentration and proportion of DGLA (n-6 PUFA) were significantly correlated with the younger onset of AIS, and the higher proportion of DHA (n-3 PUFA) was significantly correlated with the older onset of AIS.

Abstract Objectives Lower limb muscles of malnutrition stroke patients (MSP) tend to muscle atrophy more than the good nutrition patients. Muscle atrophy causes physical function (PF) and decreased activities of daily living (ADL). However, it is not clear how much the muscle atrophy in MSP affects PF and ADL. The purpose of this study was to clarify the influence of muscle atrophy of MSP on PF and ADL. Methods The subjects were 140 MSP who were 65 years or older. MSP was determined by assessing the Global Leadership Initiative on Malnutrition upon admission. For lower limb muscle atrophy, muscle thickness (QMT), pennation angle (QPA) and echo intensity (QEI) of the quadriceps of the affected and unaffected sides were measured using a B-mode ultrasound imaging device (SONON 300 L). PF and ADL were evaluated for Functional Independence Measure (FIM) and Short Physical Performance Battery (SPPB), respectively. All evaluation items were evaluated at admission and discharge. Statistical analysis used stepwise multiple regression analysis to identify factors individually associated with FIM and SPPB. QMT, QPA and QEI were set as the independent variables. We then entered the QMT, QPA and QEI of the paretic and non-paretic sides in another stepwise multiple regression model to avoid multicollinearity. In addition, we calculated an effect size (f2) for the multiple regression analysis. The statistical power of that analysis was based on f2, an alpha error of 0.05, the total sample size, and the number of predictor variables. Statistical significance was accepted as P &lt; 0.05. Results FIM and SPPB at admission and discharge were significantly independently associated with the QMT, QPA and QEI of the affected and unaffected sides (QMT: β &gt; 0.40, R2 &gt; 0.43, f2 &gt; 0.72, power &gt; 99.5%, QPA: β &gt; 0.38, R2 &gt; 0.40, f2 &gt; 0.63, power &gt; 99.2%, QEI: β &lt;−0.42, R2 &gt; 0.47, f2 &gt; 0.71, power = 99.9%). There was no multicollinearity between the independent variables in the stepwise multiple regression analyses, and the variance inflation factors ranged from 1.000 to 1.388. Conclusions It was suggested that muscle atrophy of MSP is a factor that decreases ADL and PF. Based on the above, it is necessary to assess atrophy in MSP and in some cases, intervention is required. In the future, we plan to develop effective treatments for atrophy in MSP.

Seaweed-Kappaphycus-Euchema Cottonii and Denticulum species was first cultivated at Sabah side of Sebatik in 2009. By November 2014, sixty one Sabahan seaweed farmers cultivated 122 ha or 3,050 long lines. Thirty Sabahan seaweed farmers in Kampung Pendekar (3.2 m.t dried) and 31 in Burst Point (12.5 m.t dried) produced 16 metric tonnes of dried seaweed contributed 31% to Tawau’s total production (51 m.t). The remaining 69% were from farmers in Cowie Bay that separates Sebatik from municipality of Tawau. Indonesian in Desa Setabu, Sebatik started in 2008. However, the number of Indonesian seaweed farmers, their cultivated areas and production (as well as quality) in Sebatik increased many times higher and faster than the Sabah side of Sebatik. In 2009 more than 1,401 households in Kabupaten Nunukan (including Sebatik) cultivated over 700 ha and have produced 55,098.95 and 116, 73 m.t dried seaweed in 2010 and 2011 respectively. There is a divergence in productions from farming the sea off the same island under similar weather conditions. Which of the eight explanatory factors were affecting production of seaweeds in Sebatik? Using Cobb Douglas production function, Multiple Regression analysis was conducted on 100 samples (50 Sabahan and 50 Indonesian). Results; Variable significant at α = 0.05% are Experience in farming whereas Farm size; Quantity of propagules and Location — Dummy are the variables significant at α 0.01%. Not significant are variables Fuel; Age; Number of family members involved in farming and Education level.
