Abstract
Background: We have previously reported that hepatocyte growth factor (HGF) levels were significantly associated with insulin resistance or components of the metabolic syndrome. However, it has been unknown how physical activity (PA) affects HGF levels after a long-term follow-up.
Aims: Our aim was to clarify the association between PA changes and HGF levels /cerebro-cardiovascular disease (CVD) development during 10 years follow-up period in a community-dwelling Japanese general population.
Methods: Of 1,320 subjects who received a health check-up examination in Tanushimaru town in 1999, 903 subjects (341 males and 562 females) were enrolled, who received the examination both in 1999 and 2009. We evaluated their PA levels by Baecke questionnaire in 1999 and evaluated their PA levels by a simple questionnaire in 2009. We measured the serum HGF levels by ELISA method in 1999 and 2009. We divided into four physical activity groups such as stable low PA, increased PA, decreased PA, and stable high PA. Using these questionnaires, we compared their PA and HGF levels in 10 years.
Results: A significant inverse association was found between PA changes and serum HGF levels in 10 years after adjustment for age and sex. The serum HGF levels of increased PA group were significantly lower than stable low PA (p=0.038), and the former group showed the reduced CVD development compared to the latter group after adjustment for age and sex (p=0.012).
Conclusions: Our data demonstrated that improvement of PA levels was associated with reduced HGF levels and CVD development.

Abstract
Electrospun fibers have high structural similarity to the extracellular matrix (ECM) of natural bone. Some researchers have tried to fabricate cellulose nanofibers using electrospinning method, although the fabricated fibers usually exhibited a non-uniform texture. Moreover, the fabricated mats always suffer from low biological, mechanical and structural properties. Thus, the objective of this study was first to produce a naturally occurring cellulose from banana pseudo-stem through the combination of liquefaction and bleaching processes. The native cellulose was then tried to electrospun in order to determine how a systematic approach based on a Taguchi L9 orthogonal array can be used to fabricate a defect-free fibrous mat. Finally, the electrospun cellulose mats incorporated with hydroxyapatite (HA) nanoparticles were fabricated to generate a new fibrous nanocomposite with enhanced biological and mechanical characteristics. The results revealed that among the electrospinning parameters, cellulose concentration of solution and applied voltage had the greatest effect on the morphology of the fibers. The morphological characterization of the fibrous nanocomposites showed that fibrous cellulose/HA mats had a uniform fiber texture without any significant bead, splashing or particle agglomeration. According to the mechanical tests, the samples containing the higher concentration of HA had a significantly higher elastic modulus and tensile strength. The results obtained from bioactivity analysis indicated an interesting morphological transformation into a flake-like structure which confirmed the high bioactivity of the scaffolds. Accordingly, encapsulation of HA nanoparticles inside the cellulose in the fibrous form can be promising for bone regeneration applications.
Instability Attenuation And Bifurcation Studies of A Non-Ideal Rotor Involving Time Delayed Feedback
Authors: Dasgupta Sovan Sundar 
Published: November 2021

Abstract
In non-ideal vibratory system, the excitation is a nonlinear function of system response. The dynamic behavior of such system is often characterized by an energy source with limited power. The study of instability phenomena in non-ideal rotor driven through a non-ideal energy source is of considerable current interest. The non-ideal rotor system often gets destabilized on exceeding a critical input power near the resonance. This kind of instability is termed as Sommerfeld effect marked with nonlinear jump phenomena. This paper investigates the attenuation of nonlinear jump phenomena and numerical study of bifurcations of a non-ideal unbalanced rotor system with internal damping using time delayed feedback via active magnetic bearings. The results show that the time delay indeed plays a critical role on the suppression of the jump phenomena. Following, some new insights are also revealed through a numerical study of saddle node, Hopf and trans-critical bifurcations with time delay as a bifurcation parameter. The transient analysis confirms the results obtained analytically through the steady-state consideration.
Using Geographically Weighted Regression to Assess the Relationship Between Weather and Sociodemographic Indicators and COVID-19 Infection in Iraq
Authors: Rasul Azad , Ibrahim Saad

Abstract
The impact of COVID-19 is still being recognised due to increased research, demand for the communication of uncertainties and evidence based information to help decision makers to design appropriate mitigation policies overtime. Weather and sociodemographic indicators are important to comprehensively understand rapid spread of the disease at a given spatial scale. The spatial pattern in the occurrence of disease may hint at the mechanisms that produce the disease, hence spatial analysis is very useful in studying the causes of a disease. This study evaluates the influence of weather variables, sociodemographic characteristics and their corresponding records of COVID-19 in Iraq cities. The assessments of these relationships were based on R0 estimated from the time series data of COVID-19 infections, and by using geographically weighted regression (GWR) and linear regression modelling. Global estimates of these relationships from the linear regressions are generally poor. On the contrary, the results derived from the GWR show spatially varying patterns. The lag7 of weather variables performed better compared to other lags. Among weather variables, increasing wind speed leads to risen COVID-19 infection. Population density is one of the sociodemographic characteristics that contributes to higher COVID-19 infection. COVID-19 infections, on the other hand, decreased in cities with a good health index and access to piped water. The findings of this study are therefore of great value to policy makers to design appropriate measures to reduce COVID-19 infection in Iraq and elsewhere.

Abstract
Multifunctional materials for water purification have attracted great attention due to the increased water pollution problems. However, fabricating the low-cost and recyclable separation material is still a challenge. Herein, we developed an Ag/TiO2@PDMS coated cotton fabric with self-clean ability, high flux, superior visible-light photocatalysts ability, and recyclability via the “powder + glue” strategy. The composites exhibit superhydrophobic (water contact angle 157°), and high separation efficiency. The separation efficiency of 20 times of repeated use remains 16322 Lm−2h−1 and the degradation rate of methylene blue (MB) remains almost no change. The high oil purification, catalytic property, excellent stability in harsh condition and recyclability enables the material as a satisfactory candidate for water purification.

Published: November 2021

:Cardiovascular diseases are the most common cause of death worldwide, with cardiovascular medications being amongst the most common medications prescribed. These medications have diverse effects on the heart, vascular system, as well as other tissues and organ systems. The extra cardiovascular effects have been found to be of use in the treatment of non-cardiovascular diseases and pathologies. Minoxidil is used to manage systemic hypertension with its well-known side effect of hirsutism used to treat alopecia and baldness. Sildenafil was originally investigated as a treatment option for systemic hypertension; however, its side effect of penile erection led to it being widely used for erectile dysfunction. Alpha-1 blockers such as terazosin are indicated to treat systemic hypertension but are more commonly used for benign prostatic hyperplasia and post-traumatic stress disorder. Beta blockers are the mainstay treatment for congestive heart failure and systemic hypertension but have been found useful to help in patients with intention tremors as well as prophylaxis of migraines. Similarly, calcium channel blockers are indicated in medical expulsion therapy for ureteric calculi in addition to their cardiovascular indications. Thiazides are commonly used for treating systemic hypertension and as diuretics. Thiazides can cause hypocalciuria and hypercalcemia. This side effect has led to thiazides being used to treat idiopathic hypercalciuria and associated nephrolithiasis. Spironolactone is commonly utilized in treating heart failure and as a diuretic for edema. It’s well described anti-androgen side effects have been used for acne vulgaris and hirsutism in polycystic ovarian syndrome. This review article discusses how the various extracardiovascular effects of commonly used cardiovascular medications are put to use in managing non-cardiovascular conditions.

Wstęp. Choroby tarczycy dotyczą około 20% Polaków, częściej schorzenie to występuje u kobiet niż mężczyzn. W skali roku w Polsce wykonuje się około 20 tysięcy zabiegów tego typu. Zabieg operacyjny jest sytuacją bardzo trudną dla każdego pacjenta. Wiąże się z tym odczuwanie lęku i niepokoju. Pielęgniarka to osoba, która ma bezpośredni i najczęstszy kontakt z pacjentem. Jest w stanie wykryć zaistniałe nieprawidłowości, co pozwala na szybką reakcję i podjęcie odpowiednich działań.
Cel. Celem badań była analiza różnicy poziomu wapnia przed i po zabiegu operacyjnym tarczycy.
Materiał i metody. Do przeprowadzenia badań wykorzystano metodę analizy dokumentacji. Przeanalizowana dokumentacja medyczna dotyczyła 100 pacjentów po tyreoidektomii. Uzyskane wyniki badań poddano analizie statystycznej testem χ2 dla prób niezależnych. Materiał badawczy podzielono na 5 obszarów: występowanie spadku wapnia po zabiegu operacji tarczycy, objawy towarzyszące w przypadku spadku wapnia, występowanie objawów tężyczki po zabiegu operacyjny, leczenie preparatami wapnia po operacji usunięcia tarczycy oraz wpływu poziomu wapnia na czas hospitalizacji.
Wyniki. W obszarze występowania spadku wapnia po operacji tarczycy zaobserwowano znaczny spadek. W obszarze objawów jakie pojawiły się podczas spadku wapnia zauważono, że 86% operowanych nie odczuwało żadnych objawów towarzyszących spadkowi wapnia. W analizie obszaru występowania objawów tężyczki po zabiegu wśród 72% pacjentów nie wystąpiły powikłania pooperacyjne. W obszarze leczenie preparatami wapnia 25% osób wymagało suplementacji wapnia po zabiegu operacyjnym, natomiast 75% nie wymagało suplementacji wapnia. W obszarze wpływu poziomu wapnia na czas hospitalizacji większość chorych, bo 74 % była hospitalizowana po zabiegu operacyjnym mniej niż 5 dni.

Published: November 2021

Background
The health benefits of urban green space have been widely reported in the literature; however, the biological mechanisms remain unexplored, and a causal relationship cannot be established between green space exposure and cardiorespiratory health.

Objective
Our aim was to conduct a panel study using personal tracking devices to continuously collect individual exposure data from healthy Chinese adults aged 50 to 64 years living in Hong Kong.

Methods
A panel of cardiorespiratory biomarkers was tested each week for a period of 5 consecutive weeks. Data on weekly exposure to green space, air pollution, and the physical activities of individual participants were collected by personal tracking devices. The effects of green space exposure measured by the normalized difference vegetation index (NDVI) at buffer zones of 100, 250, and 500 meters on a panel of cardiorespiratory biomarkers were estimated by a generalized linear mixed-effects model, with adjustment for confounding variables of sociodemographic characteristics, exposure to air pollutants and noise, exercise, and nutrient intake.

Results
A total of 39 participants (mean age 56.4 years, range 50-63 years) were recruited and followed up for 5 consecutive weeks. After adjustment for sex, income, occupation, physical activities, dietary intake, noise, and air pollution, significant negative associations with the NDVI for the 250-meter buffer zone were found in total cholesterol (–21.6% per IQR increase in NDVI, 95% CI –32.7% to –10.6%), low-density lipoprotein (–14.9%, 95% CI –23.4% to –6.4%), glucose (–11.2%, 95% CI –21.9% to –0.5%), and high-sensitivity C-reactive protein (–41.3%, 95% CI –81.7% to –0.9%). Similar effect estimates were found for the 100-meter and 250-meter buffer zones. After adjustment for multiple testing, the effect estimates of glucose and high-sensitivity C-reactive protein were no longer significant.

Conclusions
The health benefits of green space can be found in some metabolic and inflammatory biomarkers. Further studies are warranted to establish the causal relationship between green space and cardiorespiratory health.

Introdução: A interação dos membros da família entre si e com outros revela se os núcleos familiares são funcionais ou disfuncionais. Objetivo: Verificar funcionalidade familiar de idosos de uma USF e sua associação com perfil socioeconômico, arranjo familiar e condições de saúde/hábitos de vida. Métodos: Estudo observacional transversal analítico com amostra probabilística aleatória de idosos (≥ 60 anos). Coletaram-se informações do perfil socioeconômico, arranjo familiar e condições de saúde/hábitos de vida. A funcionalidade familiar foi avaliada por meio do APGAR, subdividindo-se em elevada disfunção (0 a 4 pontos), moderada disfunção (5 a 6 pontos) e boa funcionalidade familiar (7 a 10 pontos). Realizou-se Teste do Chi-quadrado. Resultados: Dos 187 idosos, 74% apresentam boa funcionalidade familiar. A média de idade foi 70 anos, em sua maioria eram mulheres (59%), nível de instrução ≤ 8 anos (84%), contribuem para a renda familiar (89%), moram em residência multigeracional (54%), praticam atividade de lazer (61%), não praticam atividade física (65%) e consideram a saúde como ótima ou boa (55%). A funcionalidade familiar apresentou-se normal em 79% dos idosos. Comportaram-se como fatores associados (p < 0,05): situação conjugal, morar sozinho, quantidade de moradores na casa, autoavaliação em saúde e capacidade funcional. Conclusão: A funcionalidade familiar mostrou-se, em maioria, preservada. Entende-se que é importante a dinâmica familiar no cuidado do idoso. É necessária a promoção de ações que incluam orientações e suporte às famílias que assumem o papel de cuidadoras, com o intuito de melhorar a funcionalidade familiar e garantir um envelhecimento mais digno e saudável.

Este artigo tem por objetivo avaliar a funcionalidade dos idosos que estão cadastrados em um Centro de Convivência da Terceira Idade. Trata-se de uma pesquisa descritiva, do tipo quantitativa e transversal, realizada com 51 idosos. O instrumento de avaliação foi constituído da investigação das características sociodemográficas, da funcionalidade através do Índice de Katz, escala de Lawton e nível de Atividade e Participação, de acordo com a Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF). A análise estatística foi realizada no software BioState versão 5.4, utilizando a média, desvio-padrão, o teste de correlação de Pearson para dados paramétricos e o de associação do Qui-quadrado e Spearman para os dados não paramétricos. Na avaliação das características sociodemográficas, verificou-se que 80,4% dos idosos eram do sexo feminino, com média de idade de 70.8 (±5,5) anos, viúvos (n=20) e recebiam aposentadoria (n=31). Em relação à funcionalidade, 100% dos idosos apresentaram independência para a maioria das Atividades Básicas de Vida Diária (ABVD´s),porém observou-se prevalência importante (9,8%) de incontinência urinária presente nas idosas do estudo. Para a realização das Atividades Instrumentais de Vida Diária (AIVD´s), a maioria dos idosos apresentaram independência, contudo foi identificada prevalência considerável de idosos com alguma dependência (parcial ou total) para sua execução. No que se refere à classificação da funcionalidade pela CIF, a maioria dos códigos utilizados para classificação da funcionalidade dos idosos apresentou em comum o qualificador 0. Constatou-se que a participação dos idosos em um Centro de Convivência promove maior independência e autonomia aos idosos, demonstrando a sua importância.
