Responsiveness of respiratory function in Parkinson’s Disease to an integrative exercise programme: A prospective cohort study
Authors: McMahon Laura , McGrath Denise , Blake Catherine , Lennon Olive 
Published: March 2024

Introduction
Respiratory disorders are the most common cause of death in Parkinson’s Disease (PD). Conflicting data exist on the aetiology of respiratory dysfunction in PD and few studies examine the effects of exercise-based interventions on respiratory measures. This study was conducted to better understand respiratory dysfunction in PD and to identify measures of dysfunction responsive to an integrative exercise programme.

Objectives
The objectives were to compare baseline respiratory measures with matched, published population norms and to examine immediate and longer-term effects of a 12-week integrated exercise programme on these measures.

Design
Twenty-three people with mild PD (median Hoehn & Yahr = 2) self-selected to participate in this exploratory prospective cohort study. Evaluation of participants occurred at three time points: at baseline; following the 12-week exercise programme and at 4-month follow-up.

Outcome measures
Outcome measures included: Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV1), FEV1/FVC ratio, Peak Expiratory Flow (PEF), Inspiratory Muscle Strength (MIP), Expiratory Muscle Strength (MEP), Peak Cough Flow (PCF), and Cardiovascular Fitness measures of estimated VO2 max and 6-Minute Walk Test (6MWT).

Results
Compared to published norms, participants had impaired cough, reduced respiratory muscle strength, FEV, FVC, PEF and cardiovascular fitness. Post exercise intervention, statistically significant improvements were noted in MEP, cardiovascular fitness, and PEF. However only gains in PEF were maintained at 4-month follow-up.

Conclusions
Significant respiratory dysfunction exists, even in the early stages of PD. Metrics of respiratory muscle strength, peak expiratory flow and cardiovascular fitness appear responsive to an integrative exercise programme.

ABSTRACT

Pneumocystis jirovecii is an opportunistic fungus typically causing pulmonary infection in immunocompromised persons. We present a case of Pneumocystis jirovecii pneumonia (PJP) in a patient with alcoholic hepatitis and underlying cirrhosis. PJP in patients with alcoholic hepatitis or cirrhosis is sparsely reported in literature. This condition carries a poor prognosis and high mortality. Clinicians need to recognize alcohol use resulting in liver damage as a significant etiological risk factor for PJP.

This study investigates the relationship between the profitability and liability structure of commercial banks within six Asia-Pacific countries (China, India, Australia, Japan, South Korea, and Singapore), by analyzing annual data from BankFocus for 691 banks from 2013 to 2022. The central focus of this research is to explore the impact of banks' liability structure - highlighting passive liabilities, interbank borrowing, and bond issuance - on critical profitability indicators, specifically Return on Equity (ROE) and Tier 1 Ratio (T1R). This research employs panel data analysis alongside Hausman-tested. Our findings discover the roles that passive liabilities and bond issuance play in strengthening banks' core capital and enhancing profitability. Additionally, the impact of bank deposit and borrowing services on profitability and capital across developed and developing nations within the Asia-Pacific region. The study offers practical suggestions for the banking sector, emphasizing the need for improved liability management to boost profitability. These recommendations, backed by thorough empirical research and robustness checks, provide a solid foundation for strategic policy and planning in the sector.

“把” 字句中情态动词的位置
Authors: 修 俊俊 
Published: March 2024

提要
汉语语法学界一般认为情态动词只能用于 “把” 字句的 “把” 字之前, 但语言事实显示情态动词在一定的条件下, 也能用于 “把” 字之后。 本文主要考察了情态动词用于 “把” 字之后的允准与限制、使用特点、表达效果与语法意义。 情态动词出现在 “把” 字之后, 可以出现在作为假设小句、宾语小句、推测主句之类的 “把” 字句中, 此类 “把” 字句存在时体与情态语义的限制, 即: (一) 当把字句存在现实体 “了1”, 情态动词一般不能进入。 (二) 当把字句没有时体成分出现时, “把” 后的情态动词语义无标记情况下不能是动力情态[意愿] (被动), 认识情态[推测], 而道义情态[义务], 动力情态[能力]则可以出现。 语用上则具有主观认识性、虚拟假设性、以及非现实的施为性等要求。 情态动词用于 “把” 字之后, 此时的 “把” 字句处置性减弱, 叙述性、描述性增强, “把” 字后为道义情态表现为施为句, “把” 字后为认识情态则表现为叙事句。 情态动词作为焦点敏感算子, 在 “把” 前后表现为焦点与焦点辖域的不同。 这可以从距离像似性得到解释, 距离情态动词越近的成分越容易成为焦点。 本文还为 “把” 字句表达 “完全” 意义, “把” 字之后的宾语不一定是有定成分等观点提供了形式与意义上的证据。

Published: March 2024

Abstract
To achieve real-time, sustainable, efficient, and environmentally friendly active deicing of bridge decks, a new active electric heating deicing technology based on conductive rubber as a heat source is proposed in this study. The conductive rubber was laid between asphalt layer and cement layer as the functional deicing layer, and the conductive rubber active deicing composite bridge deck pavement structure was established. The interlayer treatment method of conductive rubber active deicing composite structure was proposed. Styrene butadiene styrene–modified asphalt, PB-II type polymer-modified asphalt waterproof coating, and AMP-100 second-order reactive waterproofing coating were selected as waterproofing bonding layer. The interlayer shear performance of conductive rubber composite structure was tested and evaluated by 45° inclined shear test. Taking shear strength as the evaluation index of interlayer shear performance, the durability of interlayer shear performance of conductive rubber composite bridge deck pavement in complex environment was studied. Taking the fatigue life as the evaluation index, the interlayer fatigue resistance of conductive rubber composite bridge deck and traditional bridge deck under different stress ratios were analyzed. The results showed that shear strength between the layers of the conductive rubber active snow-melting bridge deck pavement structure using PB-II type waterproof bonding layer material was the highest, which was 0.584 MPa, and the optimum dosage was 1.5 kg/m2. Under the complex environment, the interlayer shear performance of conductive rubber composite bridge deck pavement decreases, which could still be maintained at about 70 % and had certain durability. Under the same interlaminar shear stress, the interlaminar shear fatigue life of the conductive rubber active snow-melting bridge deck was reduced by about 34 % compared with the traditional bridge deck. The research results can provide a theoretical basis and data support for the structural design of conductive rubber active deicing bridge deck pavement and the selection of waterproof bonding layer materials.
Schmidt Rebound Hardness Dependence on the Core-Size: A Correction Model Presented and Tested on Greywacke
Authors: Brabec Marek , Krmíček Lukáš 
Published: March 2024

Abstract
We determined the effect of the core sample dimensions on the measured values of the Schmidt rebound hardness and proposed a way to correct it to obtain unaffected value. The effect was previously investigated on cubes, where a clear dependence of the rebound hardness on the cube edge was proved. For cylindrical bodies, however, the problem is more complex. In order to determine and verify our model, a set of cylindrical samples was made from greywacke. After applying the correction, an improvement in the mean rebound hardness of the whole set was achieved from 80 to 98.8 % of the unaffected mean rebound value.

Effect of graphite filler on the physiochemical properties of graphite reinforced thermoset rooflite – unsaturated polyester resin composites
Authors: Karunakaran M. , Subban Ravi , Thangamani A. , Thangavel Chinnaswamy Vijayakumar 
Published: March 2024

It is well known that many polymers are insulators with poor mechanical properties, which limit their use in fuel cell applications. Physicochemical properties of the polymers can be improved by adding conductive fillers. Carbon-based materials like graphite, which provides excellent mechanical strength and thermal conductivity to the polymer matrices, is of special interest because of its abundance, low cost and light weight when compared to other carbon allotropes. In the present work we describe the physicochemical properties of rooflite unsaturated polyester resin/graphite composites. Rooflite resin and three of its composites containing 1%, 3% and 5% of graphite by weight (C-2, C-3, and C-4, respectively) were synthesized and characterized by FTIR spectral data. XRD showed two peaks at 2q = 27.37°and 55.40° with d spacing value of 3.2559 nm and 1.6571 nm, respectively, indicating the change in degree of crystallinity of the composite. The calculated crystallinity for the resin is 7.3%, and for C-2, C-3 and C-4 its values are 12.1%, 14.3%, 17.1%, respectively, evidencing the interactions between the graphite and polymer matrix. The composites showed fractured surfaces and porous rough structure with randomly distributed vascularized cavities. Agglomeration occurs, when the concentration of graphite increases. The glass transition temperature for the pure resin is 65.9 °C and increases when the resin is filled with graphite. Thermogravimetric analysis (TGA) of the composites showed no marked difference between Tmax and Tfinal, and LOI values of C-3 and C-4 are above 21%, making them self-extinguishable materials that could be used for making bipolar plates. The chemical resistance investigation against water, NaCl, NaOH, acetic acid, and toluene showed more resistance to acid than alkali solutions. These rooflite resin/graphite composites could be further studied to explore the possibility of making bipolar plates, which are an essential component of fuel cells.

Aim. To study the relationship between the clinical course of myocardial infarction (MI) with changes in left ventricular (LV) geometry and myocardial accumulation of the somatostatin analogue 99mTc-octreotide according to cardiac single-photon emission computed tomography (SPECT).Material and methods. This pilot, cohort, prospective study included 14 patients aged 37 to 72 years with primary anterior ST-segment elevation MI. Patients underwent a general clinical examination, 3-fold determination of high-sensitivity C-reactive protein (hsCRP), echocardiography on days 1-3, cardiac SPECT with 99mTc-octreotide on days 6-7 from MI onset. Statistical analysis was performed using STATISTICA 10.0, StatSoft, USA.Results. In 10 of 14 patients, 99mTc-octreotide accumulation in LV involvement area was recorded. The accumulation analysis showed varying intensity. This made it possible to form two subgroups with high and low accumulation of 99mTc-octreotide (heart-to-cavity LV ratio more and less than 1,5, respectively).Clinical characteristics and MI course, length of hospital stay did not differ between the subgroups. Occlusion of the infarct-related coronary artery (in 5 (62,5%) vs 0 (0%) patients, p=0,016) was more common in the group with increased versus decreased accumulation of 99mTc-octreotide, respectively.Laboratory analysis showed a significant increase in hsCRP upon admission in patients with increased vs decreased accumulation of 99mTc-octreotide — 31,6 mg/l (10,45-42,05) vs 6,5 mg/l (3,2-11,8), p=0,043, respectively.A significant increase in end-diastolic and end-systolic LV volumes was established. There were an increase in LV sphericity index and local contractility disruption index along with a decrease in LV ejection fraction in the subgroup with high vs reduced accumulation of 99mTc-octreotide (47,5% (45,5-51,5) vs 57,5% (54-59), p=0,020) in the damage zone, respectively. In addition, a predictive relationship between the increase in LV end-diastolic volume and the severity of 99mTc-octreotide accumulation was found (R2=0,601, F-ratio=16,562, p=0,002).Conclusion. An increase in hsCRP and early initiation of LV remodeling after primary anterior ST-segment elevation MI is accompanied by a pronounced accumulation of 99mTc-octreotide in the damage zone, detected using cardiac SPECT, as a result of systemic and local, in our opinion, macrophage-mediated post-infarction inflammation.

Published: March 2024

Introduction. In the Russian literature, we have not found data on the combination of takotsubo syndrome (TTS) and left atrial (LA) myxoma. The work analyzed our own clinical case. TTS is diagnosed in 1,0-2,5% of patients hospitalized with suspected acute coronary syndrome (ACS). Primary cardiac tumors occur in cardiology with a frequency of up to 0,2%. The most common of them are LA myxoma.Brief description. The patient was admitted to the clinic with suspected ACS. During the diagnostic search, both ACS and acute myocarditis were ruled out. An incidental finding during an echocardiographic study was LA myxoma.Discussion. Due to a stressful situation, the patient developed symptoms similar to myocardial infarction. Based on coronary angiography data (normal coronary arteries, rapid restoration of myocardial contractility, no characteristic myocardial changes, myocardial infarction and acute myocarditis were excluded and TTS was established. LA myxoma was an unexpected finding.Myxoma may contribute to TTS, presumably through central mechanisms regulating the activity of the cardiovascular system. Also important is the systemic inflammation caused by myxoma, which reduces the threshold for the development of Takotsubo cardiomyopathy in response to stress factors.

Published: March 2024

Aim. To study the features of psycho-emotional status and its clinical and prognostic significance in patients with type 1 and 2 myocardial infarction (MI).Material and methods. Of the 1293 patients hospitalized at the District Cardiology Dispensary "Center for Diagnostics and Cardiovascular Surgery" with a diagnosis of acute coronary syndrome, 277 (21,4%) patients with confirmed MI were consecutively included in the observational study. There were 194 (15,0%) patients with type 1 MI (MI1) and 83 (6,4%) with type 2 MI (MI2). MI types were determined based on the IV Universal Definition of Myocardial Infarction (UDMI). During the hospital period, type D personality was identified using the Russian version of the Type D scale-14 (DS-14), while the presence and severity of anxiety and depression was assessed using the Hospital Anxiety and Depression Scale (HADS). Follow-up was conducted through outpatient visits, telephone or email interviews for 12 months after discharge. Patients' adherence to drug therapy was assessed using 8-item Morisky Medication Adherence Scale, and quality of life (QoL) using Short Form Medical Outcomes Study (SF-36) questionnaire.Results. During the hospital period, in the group of patients with MI2, patients with type D personality were more often identified compared with MI1 (30 (36,1%) vs 55 (28,3%), p<0,05). Patients with MI2 had a significantly higher subclinical level of anxiety (34 (41,0%) vs 43 (22,2%), p=0,002), expressed level of anxiety (10 (12,1%) vs 12 (6,2%), p=0,011), as well as a significant level of depression (13 (15,7%) vs 14 (7,2%), p=0,03). At the same time, in patients with type D, regardless of MI type, subclinical levels of anxiety and depression were significantly expressed (63 (74,1%) vs 14 (7,3%) (p<0,001) and 58 (68,2%) vs 25 (13,0%) (p<0,001)). There were no significant differences in inhospital complications between the MI1 and MI2 groups depending on type D personality. After 12-month follow-up, patients with the distressed personality type had higher rate of all-cause death (5 (7,2%) vs 5 (1,6%), p<0,05 without type D), rehospitalization for decompensated heart failure (8 (11,5%) vs 9 (4,8%), p=0,04). Patients with type D were less adherent to drug therapy compared to patients without type D (30 (43,4%) vs 9 (4,8%) p=0,001, respectively), and they had lower QoL scores.Conclusion. Type D personality, the presence of anxiety and depression, high all-cause mortality and rehospitalization rate of decompensated heart failure were more often observed in MI2 compared to MI1, as well as in patients with type D, regardless of MI type. Low adherence to drug therapy and poor quality of life, regardless of MI type, were also associated with the type D personality.

Aim. To analyze the use in clinical practice of intravascular coronary assessment methods based on two-year data from the Russian Registry on the Use of Intravascular Imaging and Physiology.Material and methods. Since 2021, the Russian Registry on the Use of Intravascular Imaging and Physiology has included data from 7967 studies in 3932 patients, of which 3086 (38,7%) were studies of intravascular physiology. In 2021, 13 branches from 9 cities participated in the registry, in 2022 — 20 branches from 11 cities. For chronic coronary artery disease, 2484 (80,5%) studies were performed, for acute coronary syndrome (ACS) — 598 (19,4%).Results. In 2022, the registry included 1,9 times more intravascular functional studies compared to 2021. The contribution of different clinics was uneven — 75,7% of studies were performed in three departments. The use of non-hyperemic indexes prevailed over hyperemic ones (58%), and in ACS they were used three times more often. All coronary arteries were examined, most often the anterior descending artery. As a primary diagnosis, 1968 (63,8%) studies were performed, while for the purpose of dynamic control — 122 (3,9%), at the surgical stage — 996 (32,3%). In 85,5% (n=2638) of observations, the functional assessment of stenosis hemodynamic significance directly influenced the treatment tactics.Conclusion. The registry data indicate the significant role of functional methods among intravascular diagnostic options in the practice of domestic clinics participating in the registry. The registry demonstrated their use as a primary diagnosis 2 times more often than for coronary artery stenting. Some indications for the active use of intravascular physiology methods (in acute coronary syndrome, left coronary artery involvement) are currently controversial and require further research.

Aim. To study the association of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and monocyte chemoattractant protein-1 (MCP-1) levels with vital exhaustion (VE) among men and women aged 25-44 years in Novosibirsk.Material and methods. At the Research Institute of Internal and Preventive Medicine (Novosibirsk), during 2013-2016, a cross-sectional survey of a random representative sample of people aged 25-44 years in one of the typical districts of Novosibirsk was carried out. A total of 975 individuals were examined (403 men, 530 women). The response rate was 71%. General examination and history collection were carried out according to standard methods included in the WHO program "MONICA-psychosocial (MOPSY)". All study participants completed the Maastricht Vital Exhaustion Questionnaire (MQ).Results. High and medium VE prevailed among women (15,7% and 40,6%) than among men (5,5% and 32,8%) (p<0,001). Median serum levels of IL-6 were high VE among both sexes 1,41 [0,70;4,60] pg/ml, compared with medium VE 1,20 [0,65;2,90] pg/ml, and low VE 1,12 [0,58;2,32] pg/ml (p<0,01), and among women with high VE 1,53 [0,72;4,33] pg/ml, compared with medium VE 1,14 [0,63;2,36] pg/ml and low VE 0,95 [0,50;1,98] pg/ml (p<0,05). Serum TNF-α was higher among women with high VE (6,01±3,23 pg/ml) than with medium VE (5,63±4,16 pg/ml) and low VE (4,95±2,85 pg/ml) (p=0,025). Mean serum MCP-1 levels among both sexes, men and women, were higher with high VE (324,55±161,89 pg/ml, 270,75±107,92 pg/ml and 338,81±171,1 pg/ml) than with medium (251,78±123,4 pg/ml, 262,46±134,9 pg/ml and 245,22±115,61 pg/ml), and low VE (227,59±101,03 pg/ml, 234,51±104,53 pg/ml and 220,17±96,81 pg/ml) (p<0,001).Conclusion. An increase in the average levels of inflammation biochemical markers (IL-6, TNF-α, MCP-1) was established in individuals 25-44 years old with a high VE.
