IntroductionWe aimed to examine the change in the number and severity of visits to the emergency departments (EDs) and subsequent admissions for urgent urologic conditions in the early stage of the coronavirus disease 2019 (COVID-19) pandemic in Poland.Material and methodsWe evaluated data from 13 urologic centers in Poland and compared the number of visits to the EDs and subsequent admissions before and after the advent of COVID-19 in 2020, and before and after the escalating national restrictions. Furthermore, data on types of urologic complaints, crucial laboratory parameters, and post-admission procedures were analyzed.ResultsIn total 1,696 and 2,187 urologic visits (22.45% decrease) and 387 and 439 urologic urgent admissions (11.85% decrease) were reported in given periods in 2020 and 2019, respectively. The year-over-year difference in daily mean visits was clear (36.1 vs. 46.5; p < 0.001). Declines were seen in all complaints but device malfunction. In 2020 daily mean visits and admissions decreased from 40.9 and 9.6 before lockdowns to 30.9 (p < 0.001) and 6.9 (p = 0.001) after severe restrictions, respectively. There was a trend towards more negative laboratory parameter profiles in 2020, with patients who visited the EDs after severe restrictions having twice as high median levels of C-reactive protein (15.39 vs. 7.84, p = 0.03).ConclusionsThe observed declines in ED visits and admissions were apparent with the significant effect of national lockdowns. Our results indicate that some of the patients requiring urgent medical help did not appear at the ED or came later than they would have done before the pandemic, presenting with more severe complaints.
Development of erectile dysfunction in men treated for major depressive disorder with selective serotonin reuptake inhibitors: a systematic review
Authors: Alhuwaydi Ahmed 
Published: September 2020

Introduction: Sexual dysfunction (SD) is known to be associated with selective serotonin reuptake inhibitors (SSRIs). To determine the effect of different SSRIs on SD development in males, particularly erectile dysfunction (ED), a systematic review was conducted according to PRISMA guidelines.Material and methodsLiterature, in English language, published between January 2009 and September 2019 was searched using two electronic databases, PubMed and EMBASE. Studies were screened according to the predefined inclusion-exclusion criteria. The bibliographies of the included articles were screened to identify any relevant articles.ResultsA total of ten articles were included (8/811 articles searched; two from bibliographies of eight included articles). Treatment-emergent SD, particularly ED was observed in male participants, although the ED incidence was low, less than 2%. SSRIs – fluoxetine, escitalopram, and citalopram – showed a higher risk of ED than other SSRIs.ConclusionsThe findings indicated a positive association between SSRIs and SD. However, evidence supporting a strong link between SSRIs and ED was insufficient.

IntroductionAnthropometry and bone mineral density are linked to hormonal imbalance, which plays
a possible role in breast carcinogenesis. The current study was designed to explore the relationship
between selected anthropometric and bone mineral density parameters and the risk of breast cancer
in premenopausal and postmenopausal Saudi women.Material and methodsmethods: A cross-sectional study was carried out among premenopausal (n = 308) and
postmenopausal (n = 148) women at two Medical Cities in Riyadh, Saudi Arabia from May 2015 to
June 2016. Selected anthropometric measurements were obtained from 456 women; 213 of them had
breast cancer. Bone mineral density was also measured using dual-energy X-ray absorptiometry.ResultsGreater waist circumference was significantly correlated with a higher breast cancer risk in
premenopausal women (OR = 1.02, p = 0.03) but not in postmenopausal women. Greater triceps
skinfold thickness had been found to be significantly correlated with a higher risk of breast cancer in
premenopausal (OR = 1.06, p = 0.001) and postmenopausal (OR = 1.06, p = 0.001) women. However,
bone mineral density was not significantly associated with breast cancer risk in either group
of participants.ConclusionsBreast cancer risk was significantly associated with waist circumference and triceps
skinfold thickness in premenopausal women and with only triceps skinfold thickness in
postmenopausal women.

Published: September 2020

IntroductionHyperlipidemia refers to a group of lipid metabolism disorders characterized by increased levels of total cholesterol, triglyceride, and/or low- density lipoprotein cholesterol and/or decreased levels of high-density lipoprotein cholesterol. This study aims to investigate the effects of Lactobacillus on lipid metabolism and hepatic steatosis in male mice fed with a high-fat diet by measuring blood lipid, hepatic function and hepatocyte morphology.Material and methodsEighty male Institute of Cancer Research (ICR) mice were fed with a high-fat diet for six weeks to establish hyperlipidemic models. Then, mice were treated with a high or low concentration of Lactobacillus of human source, mouse source, or plant source, respectively.ResultsAfter three weeks of therapy, except for the human Lactobacillus treatment group, the blood cholesterol, triglyceride and low-density lipoprotein cholesterol in mice treated with Lactobacillus of mouse and plant source were lower than those in the hyperlipidemic model group. After four weeks of treatment, the levels of blood biochemical indexes in mice in all treatment groups were significantly different, when compared to those in the hyperlipidemic model group.ConclusionsLactobacillus may regulate blood lipid in mice fed with a high-fat diet. Lactobacillus can improve the high cholesterol, high blood lipid, and injury of hepatic function, and prevent further development of atherosclerosis caused by a high-fat diet to some extent. Correct dietary structure is the basis for the treatment of dietary hyperlipidemia and its complications.

IntroductionType 2 diabetes mellitus (DM) and Alzheimer’s disease (AD) are two major medical conditions that constitute a significant financial burden on most healthcare systems. Due to AD sharing “insulin resistance” mechanistic features with DM, some scientists have proposed “type 3 DM” terminology for it. This study aims to compare the prophylactic effect of exercise and metformin on cognitive brain functions in rats with type 3 DM.Material and methodsTwo groups of rats were included in the study: the control group (n = 15) and the streptozotocin-induced type 2 diabetic group (n = 45). The diabetic group was subdivided into three equal subgroups: a sedentary non-treated diabetic group, an exercised group, and a metformin-treated group. We estimated step-down avoidance task latency, serum glucose, insulin, free fatty acids (FFA), cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL) and triglycerides (TG), brain A-42 and glucose, histological changes by toluidine blue, and immunohistochemistry for brain Aβ-42 and tau-positive cells.ResultsSerum glucose, FFA, TG, cholesterol, LDL, brain Aβ-42, brain glucose, the number of hippocampal dark and degenerated cells, and brain Aβ-42 and tau-positive cells, were all significantly lower. In contrast, serum insulin and HDL, the number of hippocampal granular cells, and latency of the step-down avoidance task were significantly higher in exercised and metformin-treated groups compared to the diabetic group. There were significantly higher values of serum insulin and brain/plasma glucose ratio and number of brain tau-positive cells in the metformin-treated group than in the exercised group.ConclusionsWe can conclude that exercise can be as effective as metformin regarding prophylaxis against the deleterious effects of type 3 DM on cognitive brain functions.

Published: September 2020

PurposeAgeing is associated with deterioration and alterations in physical function, affecting community mobility, balance, skills, or daily living activities. The aim of the study was to kinematically analyse the influence of age on balance in young and older adults, as well as to compare the kinematics of the trunk and lumbar regions during Functional Reach Test (FRT).MethodsThe cross-sectional study involved 5 healthy older adults and 6 healthy young adults. Each participant performed FRT instrumentalized with 2 inertial sensors attached in the trunk (T7) and lumbar (L5-S2) regions. Direct (time and displacement) and indirect (velocity and acceleration) kinematic variables, as well as mid-range achieved in FRT were analysed.ResultsThe participants’ mean age was 73.04 ± 3.58 years among the older adults and 23.5 ± 1.52 years among the young adults. Significant differences in time (trunk: –7.61 ± 2.14 s; lumbar: –6.40 ± 1.06 s) and displacement (trunk: 16.33 ± 4.21°) were identified; in the lumbar region, no significant displacement differences were observed (<i>p</i> > 0.05). Similarly, in the partial intervals analysed during FRT (from starting position to maximum displacement/imbalance, and return to the initial position), significant differences (<i>p</i> < 0.05) were revealed in all direct and indirect variables.ConclusionsWhen comparing FRT performance in healthy young and elderly subjects from a kinematic point of view, significant differences were found in the vast majority of kinematic variables analysed in both lumbar and trunk region.
The association between achievement goal motivation and counterproductive work behavior: the moderating effect of work engagement and the Dark Triad
Authors: Derbis Romuald 
Published: September 2020

BackgroundThe objective of the article is to describe the association between counterproductive work behavior (CWB), achievement goal motivation and the moderating variables: work engagement and the Dark Triad (DT). The theoretical bases of the tested models are: the four-factor theory of achievement goal motivation (Elliot & McGregor), the CWB conception of Spector, the JD-R model of Demerouti, the work engagement model of Schaufeli and the DT conception of Paulhus and Williams.Participants and procedureAn internet study was conducted with 138 office employees as participants. The variables were measured us-ing the Polish versions of the following tools: achievement goal motivation – AGQ-R, counterproductive work behavior – CWB-C scale, work engagement – UWES, DT – the Dirty Dozen scale.ResultsThe obtained results confirm the hypothesis of the differentiated strength of the additional association of the analyzed types of achievement goal motivation (mastery approach, mastery avoidance, performance ap-proach, performance avoidance) with CWB. This link occurs in models without moderators not only for mastery avoidance. In the models with moderators, the interaction patterns are differentiated for particular types of mo-tivation; for example, work engagement interacts only with the performance approach, while DT interacts not only with the mastery approach. Three-directional interactions increase the percentage of explained variance of the models to a small degree.ConclusionsModerating effects were relatively strong within the association of performance approach with CWB. Results indicate the accuracy of the theoretical bases of the studies, as well as the need for their continuation with ac-count being taken of the types of CWB and components of DT.
Lack of control over work and organizational citizenship behavior: overwork climate as a suppressor variable
Authors: Jurek Paweł , Piotrowski Andrzej , Olech Michał , Eldridge Ewa 
Published: September 2020

BackgroundThis study investigates a suppressor effect in the relationship between lack of control over work and organiza-tional citizenship behavior (OCB). Suppressor effects operate when the addition of a predictor (in our study it is an overwork climate) increases the predictive power of another variable (lack of control over work) in predicting an outcome variable (OCB). Suppressor effects can play a valuable role in explicating the meaning of exam-ined variables by bringing into clearer focus opposing elements that are inherent – but largely hidden – in the measurement of these variables.Participants and procedureData were collected through online questionnaires in a cross-sectional study. Using a sample of Polish em-ployees (N = 580) we performed structural equation modelling (SEM) with robust maximum likelihood estima-tion to test our hypotheses.ResultsConfirming our hypothesis, we found that overwork climate, as a suppressor variable, in isolation is not corre-lated with OCB, but is strongly associated with lack of control over work, which is a significant predictor of OCB.ConclusionsIn our study, we demonstrated that both lack of control over work and organizational citizenship behaviors en-compass two dimensions simultaneously. The first, namely dedication to work (which they both share), consti-tutes the positive correlation between these two variables. The second dimension (which separates the two variables), which constitutes the negative correlation between them, is an attitude. Lack of control over work is rooted in the negative attitude and stems from the overwork climate, while organizational citizenship behaviors can be more widely associated with the positive attitude which generally stems from positive evaluation of the working environment.
A classroom-based physical activity intervention for adolescents: Is there an effect on self-efficacy, physical activity, and on-task behavior?
Authors: Cornelius Colleen , Fedewa Alicia , Toland Michael 
Published: September 2020

BackgroundClassroom-based physical activity is a newly explored avenue for providing physical activity opportunities to children within the school, but it is one that is showing academic gains in areas such as on-task behavior. The purpose of this study was to explore the impact of pedal desks placed in high school classrooms. Three main objectives were examined: 1) the possible increase in physical activity self-efficacy among high school stu-dents in the classroom, 2) the effectiveness of pedal desks on increased physical activity among high school students, and 3) the impact of pedal desks on increasing classroom on-task behavior.Participants and procedureParticipants included 114 high school students in a traditional high school setting. All of the students were en-rolled in two Reserve Officers’ Training Corps (ROTC) teachers’ classrooms. The design was quasi-experimental. Two teachers and their respective classes were randomly assigned to a treatment or control group. The study included a baseline and 2 waves. Researchers gathered demographic information of stu-dents, as well as pre- and post-data on self-efficacy and physical activity participation. On-task behavior of stu-dents was also recorded daily by researchers via momentary time sampling.ResultsThe results indicated significance for self-efficacy confidence but not barriers to physical activity participation. When examining whether self-efficacy could be connected to student heart rate, no significance was found. However, treatment students did improve their mean heart rates from baseline to treatment. This increase was significantly greater when compared to the control group.ConclusionsThis study indicates that pedal desks may be one means for feasibly increasing light physical activity during the school day. This study suggests that self-efficacy for exercise can be increased and that light intensity physical activity levels may be raised through placing pedal desks in a high school classroom. Limitations are dis-cussed.

Published: September 2020

In sports, postural balance control has been demonstrated to be one of the limiting factors of performance and a necessary component to achieve any sport technique. Team players (TP) must process and react to multiple external stimuli while executing at the same time the skills of the game. By contrast, endurance athletes (END) must perform the same gesture repetitively without a concurrent coordination of continuous stimuli-related actions. However, END are used to facilitate their physical performance by adopting cognitive strategies while performing their sport gesture. Therefore, we aimed to investigate static and dynamic balance performance in these two types of athletes, both in single and dual-task conditions. Nineteen END and sixteen TP underwent a static and a dynamic balance assessment on a dynamometric platform and an instrumented oscillating board, respectively. Among TP static but not dynamic postural balance performance was negatively affected by dual-tasking considering the area of the confidence ellipse (p < 0.001; d = 0.52) and the sway path mean speed (p < 0.001; d = 0.93). Conversely, END unaltered static balance performance but showed an overall improvement in the dynamic one when dual-tasking occurred. The limited human processing capacity accounted the worsening of the cognitive performance in both TP (p < 0.05; d = 0.22) and END (p < 0.001; d = 0.37). Although TP are more used coping dual tasking, the better performance of END could be accounted for by the employment of the external attentive focus (i.e. counting backward aloud) that called into play a strategy close to those adopted during training and competitions. These surprising results should be considered when driving and developing new trainings for team players in dual-tasking conditions.

Published: September 2020

Background
This study aimed to gain an understanding of the growth response of Phyllostachys edulis (moso bamboo) seedlings to nitrogen (N) and potassium (K) to benefit nutrient management practices and the design of proper fertilizer in nursery cultivation.

Methods
An orthogonal array L8(4×24) was used to study the effects of N forms (NH4+, NO3−), N concentrations (8, 32 mmol/L), and K+concentrations (0, 0.5, 1.5, 3 mmol/L) on seedling height, leaf number, chlorophyll content (SPAD value), biomass, root systems, and N content of P. edulis seedlings. Plants were grown in vermiculite under controlled greenhouse conditions.

Results
Our study showed that N form played a significant role in the overall performance of P. edulis seedlings, followed by the effect of N and K+ concentrations. Among the N forms, NH4+ significantly improved the growth of P. edulis seedlings compared with NO3−. Seedling height, leaf number, chlorophyll SPAD value, biomass, and root system architecture (root length, root surface area, root volume, and root tips) were greater with 8 mmol/L of NH4+ treatments than with 32 mmol/L of NH4+treatments, whereas root diameter and N content of P. edulis seedlings were higher with 32 mmol/L of NH4+ than with 8 mmol/L of NH4+. K displayed inconsistent effects on the growth of P. edulis seedlings. Specifically, seedling height, leaf number, biomass and root volume increased when the K+ concentration was increased from 0 to 0.5 mmol/L, followed by a decrease when the K+ concentration was further increased from 0.5 to 3 mmol/L. Root average diameter of the seedlings was the highest with a K+ concentration of 1.5 mmol/L, and K had some inhibitory effects on the chlorophyll SPAD value of the seedlings. P. edulis seedlings performed well with 8 mmol/L NH4+and further tolerated a higher concentration of both NH4+ and NO3−, although excessive N could inhibit seedling growth. A lower concertation of K (≤ 0.5 mmol/L) promoted seedling growth and increasing K+ concentration in the nutrient solution did not alleviate the inhibitory effect of high N on the growth of P. edulis seedlings. Therefore, NH4+nitrogen as the main form of N fertilizer, together with a low concertation of K+, should be supplied in the cultivation and nutrient management practices of moso bamboo.

Authors: Redondo Juan Carlos , de Benito Ana María , Izquierdo José María 
Published: September 2020

Background
Due to the early specialization of golf players, examining the within session sequence of training should be considered to enhance performance and prevent injury risk. The present study analyzed the effects of an 18-week concurrent training developed before or after a specific golf session in adolescence elite golfers on several performance factors.

Methods
Sixteen right-handed male golfers, were randomly divided into two groups: after golf specific training (AG) (n = 8, age: 16.77 ± 0.58 years) and before golf specific training (BG) (n = 8, age: 16.93 ± 0.59 years). AG and BG players followed a concurrent physical conditioning program (CT) after or before the golf specific training, respectively. Body mass, body fat, muscle mass, jumping ability (CMJ), ball speed (Sball), golf movements screens (GMS), power in a golf swing-specific cable woodchop (Wmax) and the perceived training load (TL) in golf specific training (TL-G) and TL in CT (TL-CT) were measured on three separate occasions.

Results
BG demonstrates a lower TL-CT than AG (p < .001, ${\eta }_{p}^{2}=0.90$) along the training program without effects on TL-G, achieving significant percentage of change on CMJ (9.38%; p = .165; d = 0.73), GMS (50.52%; p = .41, d = 0.91), Wmax (16.93%; p = .001; d = 2.02) and Sball (1.82%; p = .018; d = 0.92) without interaction effects on anthropometric measures.

Conclusions
Performing CT sessions before the regular golf training can improve specific performance factors with a lower perceived TL than the same training carried out after the regular golf training.
