Background and aims Sex differences in cardiovascular prevention have been reported, yet the role of sex with regard to different modifiable risk factors such as low-density lipoprotein cholesterol (LDL-C), systolic blood pressure (BP), and glycated hemoglobin (HbA1c) in primary care settings is unclear. Therefore, we studied sex differences in assessment and measured values of LDL-C, BP, and HbA1c in primary and secondary cardiovascular prevention delivered by general practitioners. Methods This cross-sectional study was based on electronic medical records of 59,092 primary care patients (51.9% women) aged 40–79 years in Switzerland. Multilevel regression was used to model associations of sex with assessment and measured values of LDL-C, BP, and HbA1c in 2018. Results In both primary and secondary prevention, women had lower LDL-C assessment rates (age-adjusted odds ratio (aOR) 0.71 [95% confidence interval (CI) 0.67 to 0.75] and 0.70 [CI 0.51 to 0.95]), and higher measured LDL-C values than men (age-adjusted difference 0.30 mmol/L [CI 0.25 to 0.35] and 0.28 mmol/L [CI 0.07 to 0.48]). Compared with men, women in primary prevention displayed lower BP and HbA1c assessment frequencies (aOR 0.77 [CI 0.73 to 0.81] and 0.76 [CI 0.71 to 0.80]) and measured values (age-adjusted difference -2.49 mmHg [CI -2.99 to -1.79] and -0.19% [CI -0.24 to -0.14]), while there was no sex difference in secondary prevention. Age-dependent increases in measured values of LDL-C, BP, and HbA1c were greater in women than men. Conclusions Control of LDL-C in women in primary care should be improved to reduce sex-based inequalities in prevention of cardiovascular disease.

Emerging viral diseases represent a serious issue to public and global healthcare systems and have a high potential for disease dissemination in sport/physical activity and exercise facilities. The Coronavirus disease 2019 (COVID-19) pandemic has frightened the sports and physical activity community and enthusiasts for potential transmission, dissemination, and lethality in vulnerable populations; those with chronic diseases, co-morbidities, the elderly people, and in young and healthy people. This pandemic has caused a chain reaction with cancellation of sports competitions and gymnasiums closing around the world. Currently, some sporting events are gradually resuming in certain regions of the world and also the return of competitions and training. In general, without fans and public, the sports media can only report the infection of athletes and coaching staff members. However, this situation is dynamic - the world is currently experiencing the second wave of the disease; with the safety and containment measures for the disease is changing daily. The purpose of this article is to present information concerning the COVID-19 pandemic, to clarify health issues for professionals and people connected to sport and physical activity venues, presenting information to assist in education and health promotion and prevention. The time is now for making changes, reviewing the actions and conducts necessary for prevention, and most important not letting our guard down, even as vaccines become available for all people in the world. Remembering that even after getting vaccinated, it is necessary to continue with safety measures such as, for example, the use of facial masks and social distance and hygiene, that is, washing your hands frequently and/or sanitizing with 70% alcohol. We can't let our guard down for COVID-19.

Many affected persons use dietary supplements for self-treating their symptoms, but little is known about the specific characteristics and preferences of these patients. Even less evidence exists about the consequences of a specific dietary supplement usage on health care utilization. The aim of this study was to explore characteristics, preferences and the impact on health care utilization in patients using a specific over-the-counter dietary supplement, which is promoted for improving sleeping disturbances.Patients and Methods: We conducted a structured survey and invited a sample of 297 customers of a specific dietary supplement to participate. The survey was open between June and September 2020. Participants were invited by email. All participants accepted an informed consent.Results: A total of 127 customers participated in the survey (participation rate: 42.8%). Of them, 87.7% were female and the mean age 50.5 years. Participants reported an overall good improvement of symptoms (7.66 on a ten-point Likert-scale) and showed a strong belief in the effectiveness of supplements in general; 67% of participants reported that the intake led to fever physician encounters, and 48.3% reported that they could stop the intake of other pharmaceutical sleeping drugs.Conclusion: A significant proportion of participants reported a substantial reduction in pharmaceutical drug use and health care utilization. While these self-reports lack an adequate control, they are still real consumer experiences, and the large beneficial effects – whether placebo or not – explain the popularity of such supplements and their therapeutic potential in sleeping disorders.Keywords: supplement use, sleeping disorders, usage patterns, drugs, health care utilization

Background Micronutrient laboratory tests (MLT) are increasing in many healthcare systems. This study assessed time trends of annual MLT incidence in the Swiss population and examined the frequency of specific MLT, defined as the number of yearly tests performed in individual persons. Methods For annual time trends, we used a longitudinal design with a seven-year observation period (2012-2018) and for yearly testing frequency we used a cross-sectional design (2018 only). The database consisted of nationwide insurance claims from adult persons. Results Persons with MLT compared to persons without were older (mean age 57.1 years vs 48.6 years) and to a higher proportion female (65.1% vs 45.5%). Between 2012 and 2018, we included 6.7 million person years and found an increase in the proportion of persons receiving any MLT from 24.5% to 35.0%. Tests with strongest absolute increase during the observation period were vitamin D (from 7.4% of persons to 20.4%), vitamin B12 (from 9.0% to 17.6%) and ferritin (from 17.4% to 26.6%). In 2018, vitamin D and vitamin B12 tests were performed more than once in 4.5% and 3.3% of the population, respectively. Conclusion We found that the Swiss population undergoes MLT with high and increasing frequency. Testing for vitamin D, vitamin B12 and ferritin is very common and of questionable appropriateness.

Background and purpose Kettlebell exercise have become popular because of its ability to simultaneously train aerobic/anaerobic systems, low cost and easy access, and the great potential for physical fitness programs with a focus on public health. However, little is known about its effects on mood status, sleep, and quality of life (QOL) parameters. The aim of the present study was to examine the effects of kettlebell training/detraining on the prevention of depressive and anxiety symptoms and QOL and sleep quality. Methods The sample was composed of 17 healthy women (age: 26.0 ± 5.0 years; body mass: 60.9 ± 12.5 kg; height: 164.6 ± 5.5 cm). The study was organized into four consecutive phases: pre-intervention (PRE), intervention (kettlebell training, 12 weeks, three times/week), post-intervention (POST) and detraining (D, four weeks). The questionnaires SF-36 (QOL), Beck (depressive symptoms), State-Anxiety Inventory (acute anxiety symptoms), POMS (mood state) and the Pittsburgh Sleep Quality Index (sleep quality) were administered at PRE/POST/D phases. Results QOL, anxiety, sleep quality, and mood state exhibited no differences between PRE/POST/D. Levels of depressive symptoms significantly decreased (22.0%, p = 0.003) between PRE and POST phases, and remained low and similar to POST levels after D. Conclusion Twelve weeks of kettlebell training was able to reduce and prevent depressive/anxiety symptoms in healthy women and these results were maintained after short-term detraining. Thus, kettlebell training might be considered an alternative method on the promotion of mental health and prevention of mood disorders and consequently can improve QOL even in health people.

Background Urinary tract infections are one of the most common reasons for prescribing antibiotics in primary care. Current guidelines recommend fosfomycin, nitrofurantoin, or trimethoprim - sulfamethoxazol as empiric first line antimicrobial agents in uncomplicated infections. However, there is evidence that the use of fluoroquinolones, which are no longer recommended, is still inappropriate high. We determined antibiotic prescription patterns, quality and factors affecting antibiotic prescriptions in urinary tract infections in primary care in Switzerland. Methods From June 2017 to August 2018, we conducted a cross-sectional study in patients suffering from a urinary tract infection (UTI). Patient and general practitioners characteristics as well as antibiotic prescribing patterns were analysed. Results Antibiotic prescribing patterns in 1.352 consecutively recruited patients, treated in 163 practices could be analysed. In 950 (84.7%) patients with an uncomplicated UTI the prescriptions were according to current guidelines and therefore rated as appropriate. Fluoroquinolones were prescribed in 13.8% and therefore rated as inappropriate. In multivariable analysis, the age of the general practitioner was associated with increasing odds of prescribing a not guideline recommended antibiotic therapy. Conclusions We found a high degree of guideline conform antibiotic prescriptions in patients with an uncomplicated urinary tract infection in primary care in Switzerland. However, there is still a substantial use of fluoroquinolones in empiric therapy.

Ultra-marathon running has enjoyed increasing popularity, with the number of master ultra-marathon runners growing annually. This study presents a case of a 51-year-old highly experienced long-distance runner (body mass: 65.1 kg, body height: 168 cm), who took part in a 48-h ultra-marathon race held in 2010, but dropped out of the competition due to acute cardiac problems manifested after 16 h of running and having completed a distance of 129 km. Two weeks following the race, intense cardiac examination was performed to explain the drop-out due to chest pain. A 12‑lead electrocardiogram, a 2D transthoracic echocardiography in 3 apical projections of the left ventricle, a computed tomography of the chest, an invasive coronary angiography and a maximal oxygen uptake (VO 2max ) test were performed. The 12-lead ECG revealed a negative T wave in III and aVF without morphological abnormalities. The echocardiographic examinations presented a normal size and function of the heart chambers, and a normal valvar structure and function (only trivial mitral and tricuspid regurgitation was observed). The invasive coronary arteriography – due to an increased calcium score in the CT scan – showed only a non-significant systolic dynamic narrowing in the eighth segment of the left anterior descending artery due to a muscle bridge. The physical performance characteristics of the athlete and a follow-up history of his athletic activity showed that the cardiac problems he had experienced during the ultra-marathon race did not prevent him from being active in sport.

Summary Background Increasing cancer drug prices are a challenge for patients and health systems in the USA and Europe. By contrast with the USA, national authorities in European countries often directly negotiate drug prices with manufacturers. The American Society of Clinical Oncology (ASCO) and the European Society for Medical Oncology (ESMO) developed frameworks to evaluate the clinical value of cancer therapies: the ASCO-Value Framework (ASCO-VF) and the ESMO-Magnitude of Clinical Benefit Scale (ESMO-MCBS). We aimed to assess the association between the clinical benefit of approved cancer drugs based on these frameworks and their drug prices in the USA and four European countries (England, Switzerland, Germany, and France). Methods For this cost–benefit analysis, we identified all new drugs with initial indications for adult cancers that were approved by the US Food and Drug Administration between Jan 1, 2009, and Dec 31, 2017, and by the European Medicines Agency up until Sept 1, 2019. For drugs indicated for solid tumours, we assessed clinical benefit using ASCO-VF and ESMO-MCBS. We compared monthly drug treatment costs between benefit levels using hierarchical linear regression models, and calculated Spearman's correlation coefficients between costs and benefit levels for individual countries. Findings Our cohort included 65 drugs: 47 (72%) drugs were approved for solid tumours and 18 (28%) were approved for haematological malignancies. The monthly drug treatment costs in the USA were a median of 2·31 times (IQR 1·79–3·17) as high as in the assessed European countries. There were no significant associations between monthly treatment costs for solid tumours and clinical benefit in all assessed countries, using the ESMO-MCBS (p=0·16 for the USA, p=0·98 for England, p=0·54 for Switzerland, p=0·52 for Germany, and p=0·40 for France), and for all assessed countries except France using ASCO-VF (p=0·56 for the USA, p=0·47 for England, p=0·26 for Switzerland, p=0·23 for Germany, and p=0·037 for France). Interpretation Cancer drugs with low or uncertain clinical benefit might be prioritised for price negotiations. Value frameworks could help identify therapies providing high clinical benefit that should be made rapidly available across countries.

Zusammenfassung. Bei Gicht steht im klinischen Alltag meist die akute Attacke im Vordergrund. Als diagnostischer Goldstandard gilt dabei der Kristallnachweis in der Gelenksflüssigkeit mittels Polarisationsmikroskopie. Auch bildgebende Verfahren wie der hochauflösende Ultraschall sind von Nutzen. Zur Behandlung der akuten Gichtattacke dienen nicht-steroidale Antirheumatika, Steroide und Colchizin (in der Schweiz nicht zugelassen, über Apotheken erhältlich). Ebenso wichtig wie Diagnose und Therapie der akuten Attacke ist aber die langfristige Behandlung der Hyperurikämie, um so weitere Gichtschübe sowie mögliche renale, kardiale oder metabolische Komplikationen zu verhindern. Daher sollte bei bestätigter Gichtdiagnose neben nicht-medikamentösen Massnahmen auch eine harnsäuresenkende Therapie, mit dem Zielwert von

Background Financial incentives are often used to improve quality of care in chronic care patients. However, the evidence concerning the effect of financial incentives is still inconclusive. Objective To test the effect of financial incentives on quality measures (QMs) in the treatment of patients with diabetes mellitus in primary care. We incentivized a clinical QM and a process QM to test the effect of financial incentives on different types of QMs and to investigate the spill-over effect on non-incentivized QMs. Design/Participants Parallel cluster randomized controlled trial based on electronic medical records database involving Swiss general practitioners (GPs). Practices were randomly allocated. Intervention All participants received a bimonthly feedback report. The intervention group additionally received potential financial incentives on GP level depending on their performance. Main Measures Between-group differences in proportions of patients fulfilling incentivized QM (process QM of annual HbA1c measurement and clinical QM of blood pressure level below 140/95 mmHg) after 12 months. Key Results Seventy-one GPs (median age 52 years, 72% male) from 43 different practices and subsequently 3838 patients with diabetes mellitus (median age 70 years, 57% male) were included. Proportions of patients with annual HbA1c measurements remained unchanged (intervention group decreased from 79.0 to 78.3%, control group from 81.5 to 81.0%, OR 1.09, 95% CI 0.90–1.32, p = 0.39). Proportions of patients with blood pressure below 140/95 improved from 49.9 to 52.5% in the intervention group and decreased from 51.2 to 49.0% in the control group (OR 1.16, 95% CI 0.99–1.36, p = 0.06). Proportions of non-incentivized process QMs increased significantly in the intervention group. Conclusion GP level financial incentives did not result in more frequent HbA1c measurements or in improved blood pressure control. Interestingly, we could confirm a spill-over effect on non-incentivized process QMs. Yet, the mechanism of spill-over effects of financial incentives is largely unclear.

Background: Muscle soreness after a competition or a training session has been a concern of runners due to its harmful effect on performance. It is not known if stronger individuals present a lower level of muscle soreness after a strenuous physical effort. The aim of this study was to investigate whether the pre-race muscle strength or the V˙O2max level can predict muscle soreness 24, 48 and 72 h after a full marathon in men. Methods: Thirty-one marathon runners participated in this study (age, 40.8 ± 8.8 years old, weight, 74.3 ± 10.4 kg, height, 174.2 ± 7.6 cm, maximum oxygen uptake, V˙O2max, 57.7 ± 6.8 mL/kg/min). The isokinetic strength test for thigh muscles and the V˙O2max level was performed 15–30 days before the marathon and the participants were evaluated for the subjective feeling of soreness before, 24, 48 and 72 h after the marathon. Results: The participants presented more pain 24 h after the race (median = 3, IQR = 1) than before it (median = 0, IQR = 0) (p &lt, 0.001), and the strength values for the knee extensor muscles were significantly associated with muscle soreness assessed 24 h after the race (p = 0.028), but not 48 (p = 0.990) or 72 h (p = 0.416) after the race. The V˙O2max level was not associated with the muscle pain level at any moment after the marathon. Conclusions: Marathon runners who presented higher muscular strength for the knee extensor muscles presented lower muscle soreness 24 h after the race, but not after 48 h or 72 h after the race. Therefore, the muscle soreness level 3 days after a marathon race does not depend on muscle strength.

IMPORTANCE The high cost of cancer medicines is a public health challenge. Policy makers in the US and Europe are debating reforms to drug pricing that would cover both the prices of new medicines when entering the market and price increases after they are launched. OBJECTIVE To assess launch prices, postlaunch price changes, and clinical benefit of cancer drugs in the US compared with 3 European countries (England, Germany, and Switzerland). DESIGN, SETTING, AND PARTICIPANTS This economic evaluation identified all new drugs that were approved for use in the US, England, Germany, and Switzerland with initial indications for treatment of adult solid tumor and hematologic cancers. Analysis included drugs approved by the US Food and Drug Administration between January 1, 2009, and December 31, 2019, and by the European Medicines Agency and Swissmedic until December 31, 2019. Prices were adjusted for currency and inflation. Clinical benefit of drugs indicated for solid tumors was assessed using the American Society of Clinical Oncology Value Framework and European Society for Medical OncologyMagnitude of Clinical Benefit Scale. Using Spearman rank correlation coefficients, correlations between clinical benefit and launch prices and postlaunch price changes for each country were evaluated. MAIN OUTCOMES AND MEASURES Launch prices, postlaunch price changes, and clinical benefit of cancer drugs. RESULTS The cohort included 65 drugs: 47 (72%) approved for solid tumors and 18 (28%) for hematologic cancers. In all countries, the lowest median monthly treatment costs at launch were greater in 2018-2019 vs 2009-2010: $14 580 vs $5790 in the US, $5888 vs $4289 in Germany, $6593 vs $5784 in Switzerland, and $6867 vs $3939 in England. Between 2009 and 2019, 48 of 65 (74%) cancer drugs had price increases in the US that were greater than inflation. Only 1 of 62 (2%) drugs in England, 0 of 60 drugs in Germany, and 7 of 56 drugs (13%) in Switzerland had a median price increase greater than inflation. There were no associations between launch prices or postlaunch price changes and clinical benefit in any assessed country. CONCLUSIONS AND RELEVANCE During this economic evaluation study period, launch prices of cancer drugs were substantially higher in the US than in the assessed similar high-income European countries, a gap that increased in the years after approval. Cancer drug prices frequently increased faster than inflation in the US but decreased on inflation-adjusted terms in Europe. Price changes were not associated with clinical benefit in any country.

Background and objective: Existing research shows that the sex differences in distance-limited ultra-cycling races decreased with both increasing race distance and increasing age. It is unknown, however, whether the sex differences in time-limited ultra-cycling races will equally decrease with increasing race distance and age. This study aimed to examine the sex differences regarding performance for time-limited ultra-cycling races (6, 12, and 24 h). Methods: Data were obtained from the online database of the Ultra-Cycling Marathon Association (UMCA) of time-limited ultra-cycling races (6, 12, and 24 h) from the years 1983–2019. A total of 18,241 race results were analyzed to compare cycling speed between men and women by calendar year, age group (&lt, 29, 30–39, 40–49, 50–59, 60–69, &gt, 70 years), and race duration. Results: The participation of both men (85.1%) and women (14.9%) increased between 1983 and 2019. The age of peak performance was between 40 and 59 years for men and between 30 and 59 years for women. Between 2000 and 2019, more men (63.1% of male participants and 52.2% of female participants) competed in 24 h races. In the 24 h races, the sex difference decreased significantly in all age groups. Men cycled 9.6% faster than women in the 12 h races and 4% faster in the 24 h races. Both women and men improved their performance significantly across the decades. Between 2000 and 2019, the improvement in the 24 h races were 15.6% for men and 21.9% for women. Conclusion: The sex differences in cycling speed decreased between men and women with increasing duration of ultra-cycling races and with increasing age. Women showed a greater performance improvement than men in the last 20 years. The average cycling speed of men and women started to converge in the 24 h races.

It has been well-documented that female and male athletes differ in many physiological and psychological characteristics related to endurance performance. This sex-based difference appears to be associated with their nutritional demands including the patterns of supplement intake. However, there is a paucity of research addressing the sex differences in supplement intake amongst distance runners. The present study aimed to investigate and compare supplement intake between female and male distance runners (10 km, half-marathon, (ultra-)marathon) and the potential associations with diet type and race distance. A total of 317 runners participated in an online survey, and 220 distance runners (127 females and 93 males) made up the final sample after a multi-stage data clearance. Participants were also assigned to dietary (omnivorous, vegetarian, vegan) and race distance (10-km, half-marathon, marathon/ultra-marathon) subgroups. Sociodemographic characteristics and the patterns of supplement intake including type, frequency, dosage, and brands were collected using a questionnaire. One-way ANOVA and logistic regression were used for data analysis. A total of 54.3% of female runners and 47.3% male runners reported consuming supplements regularly. The frequency of supplement intake was similar between females and males (generally or across dietary and distance subgroups). There was no significant relationship for sex alone or sex interactions with diet type and race distance on supplement intake (p &lt, 0.05). However, a non-significant higher intake of vitamin and mineral (but not CHO/protein) supplements was reported by vegan and vegetarian (but not by omnivorous) females compared to their male counterparts. In summary, despite the reported findings, sex could not be considered as a strong modulator of supplement intake among different groups of endurance runners.

Urinary tract infections (UTIs) are frequent reasons for consultation in primary care and the choice of empirical antibiotic therapy is determined by the local resistance patterns of the causative uropathogens.

Background: The environment can play a relevant role in performance in runners. This study aimed to verify the distribution of the best European road runners across the continent, and to investigate variables related to country representatives in the European Senior outdoor top list 2019. Methods: The sample comprised 563 European runners, aged 18–48 years, ranked in the European Senior outdoor top list 2019 for distances of 10–42 km. Country-related variables were gross domestic product (GDP), competition place, population size, and sports investment. The countries were categorized as “top ten countries” or “other countries”. Binary logistic regression was used for analysis. Results: The United Kingdom showed the highest prevalence of runners in the ranking (men—17.6%, women—23.0%), followed by Spain (male ranking—12.1%) and Germany (female ranking—8.6%). For men, sports investment (OR = 1.13, CI95% = 1.03–1.28) and country GDP (OR = 0.96, CI95% = 0.93–0.98) showed an association with the chances of the athlete to reach the Top 10 ranking, while among women, the only variable significantly related was the competition venue (OR = 3.97, CI95% = 1.40–11.23). Conclusion: As in other sports considered “non-expensive”, the economic and demographic characteristics of the place where athletes train can provide advantages in performance.

The aim of the present study is to evaluate the effect of Ramadan observance (RAM) on decision-making in Kung-Fu athletes. Fourteen male Kung-Fu athletes (mean age = 19 ± 3 years) completed two test sessions: before Ramadan (BR) and at the end of Ramadan (ER). In the afternoon of each session (between 16:00 h and 18:00 h), participants completed: Epworth Sleepiness Scale (ESS), Profile of Mood States (POMS), and Pittsburg Sleep Quality Index (PSQI). Subjects also reported subjective fatigue, alertness, and concentration. Additionally, all participants performed video-based decision-making tasks (i.e., reaction time and decision-making). Results indicated that reaction time decreased by 30% at ER vs. BR (p &lt, 0.01). However, decision-making decreased by 9.5% at ER vs. BR (p &lt, 0.05). PSQI results indicated sleep quality score, sleep duration, and sleep efficiency were negatively affected at ER compared to BR (p &lt, 0.05). ESS was higher at ER compared to BR (p &lt, 0.05). In addition, fatigue scores, estimated by the POMS and current subjective feelings (i.e., fatigue, concentration, and alertness), were also negatively affected at ER compared to BR (p &lt, 0.05). In conclusion, Ramadan observance was associated with an adverse effect on sleep and decision making, as well as feelings of fatigue, alertness, and concentration.

Literature suggests a large evidence-performance gap, especially regarding pain management. Therefore, the monitoring of treatment patterns is important to ensure high quality of treatment. This study aimed to describe treatment patterns specific to patients with diagnostic imaging of the spine for LBP.Patients and Methods: The study was retrospective observational and based on health claims data from 2015 to 2019 provided by a Swiss health insurance company covering around 12% of the population. Patients, ≥ 18 years of age, with diagnostic imaging of the spine were included and observed 12 months before and after imaging. Patients with back surgery or comorbidities associated with the use of pain medications were excluded.Results: In total, 60,822 patients (mean age: 53.5 y, 56.1% female) were included and 85% received at least one pain medication. Of these, non-steroidal anti-inflammatory drugs, paracetamol, or opioids were prescribed in 88.6%, 70.7%, and 40.3% of patients, respectively. Strong opioids were used in 17% of patients given opioids. Patients with combinations of diagnostic imaging methods had the highest odds of receiving pain medication prescriptions (1.81, 95% CI: 1.66, 1.96, P < 0.001). Prescribed defined daily doses corresponded to short-term therapies.Conclusion: Although the majority of patients received non-opioid short-term therapies, we found a substantial use of opioids, and in particular, a relative high usage of strong opioids. Our results highlighted the importance of both patient and healthcare provider awareness regarding the prudent treatment of LBP.Keywords: low back pain medication, radiology, diagnostic imaging, NSAIDs, opioids, non-pharmacologic therapies

AimDespite the increasing popularity of outdoor endurance running races of different distances, little information exists about the role of training and physiological characteristics of recreational runners. The aim of the present study was (a) to examine the role of training and physiological characteristics on the performance of recreational marathon runners and (b) to develop a prediction equation of men’s race time in the “Athens Authentic Marathon.”MethodsRecreational male marathon runners (n= 130, age 44.1 ± 8.6 years)—who finished the “Athens Authentic Marathon” 2017—performed a series of anthropometry and physical fitness tests including body mass index (BMI), body fat percentage (BF), maximal oxygen uptake (VO2max), anaerobic power, squat, and countermovement jump. The variation of these characteristics was examined by quintiles (i.e., five groups consisting of 26 participants in each) of the race speed. An experimental group (EXP,n= 65) was used to develop a prediction equation of the race time, which was verified in a control group (CON,n= 65).ResultsIn the overall sample, a one-way ANOVA showed a main effect of quintiles on race speed on weekly training days and distance, age, body weight, BMI, BF, and VO2max (p≤ 0.003, η2≥ 0.121), where the faster groups outscored the slower groups. Running speed during the race correlated moderately with age (r= −0.36,p< 0.001) and largely with the number of weekly training days (r= 0.52,p< 0.001) and weekly running distance (r= 0.58,p< 0.001), but not with the number of previously finished marathons (r= 0.08,p= 0.369). With regard to physiological characteristics, running speed correlated largely with body mass (r= −0.52,p< 0.001), BMI (r= −0.60,p< 0.001), BF (r= −0.65,p< 0.001), VO2max (r= 0.67,p< 0.001), moderately with isometric muscle strength (r= 0.42,p< 0.001), and small with anaerobic muscle power (r= 0.20,p= 0.021). In EXP, race speed could be predicted (R2= 0.61, standard error of the estimate = 1.19) using the formula “8.804 + 0.111 × VO2max + 0.029 × weekly training distance in km −0.218 × BMI.” Applying this equation in CON, no bias was observed (difference between observed and predicted value 0.12 ± 1.09 km/h, 95% confidence intervals −0.15, 0.40,p= 0.122).ConclusionThese findings highlighted the role of aerobic capacity, training, and body mass status for the performance of recreational male runners in a marathon race. The findings would be of great practical importance for coaches and trainers to predict the average marathon race time in a specific group of runners.

The Ironman is one of the most popular triathlon events in the world. Such a race involves a great number of tactical decisions for a healthy finish and best performance. Dehydration is widely postulated to decrease performance and is known as a cause of dropouts in Ironman. Despite the importance of hydration status after an Ironman triathlon, there is a clear lack of review and especially meta-analysis studies on this topic. Therefore, the objective was to systematically review the literature and carry out a meta-analysis investigating the hydration status after an Ironman triathlon. We conducted a systematic review of the literature up to June 2016 that included the following databases: PubMed, SCOPUS, Science Direct and Web of Science. From the initial 995 references, we included 6 studies in the qualitative analysis and in the meta-analysis. All trials had two measures of hydration status after a full Ironman race. Total body water, blood and urine osmolality, urine specific gravity and sodium plasma concentration were considered as hydration markers. Three investigators independently abstracted data on the study design, sample size, participants’ and race characteristics, outcomes, and quantitative data for the meta-analysis. In the pooled analysis, it seems that the Ironman event led to a moderate state of dehydration in comparison to baseline values (SMD 0.494; 95% CI 0.220 to 0.767; p = 0.001). Some evidence of heterogeneity and consistency was also observed: Q = 19.6; I2 = 28.5%; τ2 = 2.39. The results suggest that after the race athletes seem to be hypo-hydrated in comparison to baseline values.

Aims: To synthesize the empirical evidence on the effectiveness of shared decision making (SDM) compared to usual care for prostate cancer (PC) treatment. Methods and results: A systematic review of academic (MEDLINE, EMBASE, Cochrane Library, CINHAL, PsychINFO, and Scopus) and grey (clinicaltrials.gov, WHO trial search, meta-Register ISRCTN, Google Scholar, opengrey, and ohri.ca) literature, also identified from contacting authors and hand-searching bibliographies. We included randomized controlled trials (RCTs): 1) comparing SDM to usual care for decisions about PC treatment, 2) conducted in primary or specialized care, 3) fulfilling the key SDM features, and 4) reporting quantitative outcome data. Four RCTs from Canada (n=3) and the USA were included and comprised 1,065 randomized men, most (89.8%) of whom were in PC stage T1-T2. The studies reported 24 outcome measures. In 62.5% study estimates, SDM was similar to usual care at improving patient satisfaction and mood, and at reducing decisional conflict and decisional regret. In 37.5% study estimates, SDM significantly improved knowledge, perception of being informed and patient-perceived quality of life (QoL) at four weeks. There was a dearth of outcome data, particularly on the adherence to treatment and on patient-important and clinically relevant health outcomes such as symptoms and mortality. Conclusion: SDM may positively influence men’s knowledge and may have a positive but short-term effect on patient-perceived QoL. The (long-term) effects of SDM on patient-related outcomes for decisions about PC treatment are unclear. Future research needs consensus about the interventions and outcomes needed to evaluate SDM and should address the absence of evidence on health outcomes.

Background The aim of the study was to examine the prevalence of and factors associated with antidepressant (AD) prescriptions in order to draw a comprehensive picture of prescribing practices in Switzerland. Method We conducted a population-based, cross-sectional descriptive study using a large Swiss healthcare claims database, covering approximately 13% of the Swiss population. AD prescription was determined by identifying patients (N = 105,663) with health claims data of at least 1 AD prescription in the year 2016. AD medication was identified using ATC-codes classified by the World Health Organisation. Univariate, bivariate and multivariate analyses using logistic regression were performed. Results The extrapolated 1-year prevalence of AD prescription was 8.7% (95% CI, 8.7–8.8) with two thirds of AD recipients being female and the average age being 59 years (SD = 19.1). The regional distribution of prescription rates varied between cantons and ranged from 6.5 to 11.7%. Logistic regression revealed higher prescription rates among females compared to males (OR: 1.52) and an increased probability of AD prescription by age up until 54 years (OR: 2.25) and ≥ 85 years (OR: 2.32). Comorbidity is associated with higher odds (OR: 3.26 with 1–2 comorbidities) and enrollment in a managed care plan (compared to standard care) with lower odds for an AD prescription (OR: 0.85). Conclusion This study is the first in Switzerland to describe the prevalence of and factors associated with AD prescription based on a large health claims database reflecting routine care. The results provide important information about regional variation, prescription source, and potential over-prescription in the treatment of depressive disorders.

Pacing strategies have mainly been investigated for runners, but little is known for cross-country skiers. The aim of the present study was to examine the effects of performance and age on pacing strategies in cross-country skiing. All finishers (women, n = 19,375; men, n = 86,190) in the ‘Engadin Ski Marathon’ (42 km) between 1998 and 2016 were analysed for the percentage change of speed at 10 km (Change A), 20 km (Change B) and 35 km (Change C). They were classified in performance groups according to quartiles of average race speed (Q1, Q2, Q3 and Q4) and in 5-year age groups (2 = 0.215). A small impact of age group × performance group interaction on Change A was shown in women (p < 0.001, η2 = 0.026) and men (p < 0.001, η2 = 0.025), where Q1 augmented and Q4 attenuated the decrease in speed with aging. However, the impact of age group × performance group interaction on Change B and C was trivial (p = 0.002, η2 ≤ 0.010). Based on these findings, it was concluded that the differences in pacing among age groups depended on the performance level. Thus, the coaches and fitness trainers working with cross-country skiers should advise their athletes to consider both age and performance.

Osteoporosis is a systemic disease affecting half of women over the age of 50 years. Considering that almost 90% of peak of bone mass is achieved until the second decade of life, ensuring a maximal bone mineral content acquisition may compensate for age-associated bone loss. Among several other factors, physical activity has been recommended to improve bone mass acquisition. However, it is unknown whether athletes involved with sports with different impact loading characteristics differ in regards to bone mass measurements.To compare the bone mass content, bone mass density and lean mass of young female soccer players (odd-impact loading exercise), handball players (high-impact loading exercises) and non-athletes.A total of 115 female handball players (15.5 ± 1.3 years, 165.2 ± 5.6 cm and 61.9 ± 9.3 kg) and 142 soccer players (15.5 ± 1.5 years, 163.7 ± 6.6 cm and 56.5 ± 7.7 kg) were evaluated for body composition using a dual-emission X-ray absorptiometry system, and 136 female non-athletes (data from NHANES) (15.1 ± 1.32 years, 163.5 ± 5.8 cm and 67.2 ± 19.4 kg) were considered as the control.Handball players presented higher bone mass content values than soccer players for upper limbs (294.8 ± 40.2 g and 270.7 ± 45.7 g, p 0.001), lower limbs (1011.6 ± 145.5 g and 967.7 ± 144.3 g, p = 0.035), trunk (911.1 ± 182.5 g and 841.6 ± 163.7 g, p = 0.001), ribs (312.4 ± 69.9 g and 272.9 ± 58.0 g, p 0.001), spine (245.1 ± 46.8 g and 222.0 ± 45.1 g, p 0.001) and total bone mass (2708.7 ± 384.1 g and 2534.8 ± 386.0 g, p 0.001). Moreover, non-athletes presented lower bone mass content for lower limbs (740.6 ± 132.3 g, p 0.001), trunk (539.7 ± 98.6 g, p 0.001), ribs (138.2 ± 29.9 g, p 0.001), pelvis (238.9 ± 54.6 g, p 0.001), spine (152.8 ± 26.4 g, p 0.001) and total bone mass (1987.5 ± 311.3 g, p 0.001) than both handball and soccer players. Handball players also presented higher bone mass density values than soccer players for trunk, ribs and spine (p 0.05) and handball and soccer players presented higher bone mass density than non-athletes for all measurements (p 0.005). Finally, the non-athletes' lower limb lean mass was lower than soccer and handball players values (p 0.05).Adolescent females engaged in handball training for at least one year present higher bone mass contents than those who are engaged in soccer training, which, in turn, present higher bone mass contents than non-athletes. These results might be used by physicians and healthcare providers to justify the choice of a particular sport to enhance bone mass gain in female adolescents.

Background and Objectives: We examined the possible trend in the age of peak performance in elite endurance athletes according to sex, continent of athletes’ national citizenship, and ranking position. Since performance is a multifactorial trait, this information can be used to guide the long-term training and to plan the strategies related to the selection process of athletes. Materials and methods: Information of 1852 professional athletes, classified as top 20 performance of each year in marathon and half-marathon events between 1997 and 2020 were considered. Analysis of variance was computed to test differences in age between sex, continent, and rank position. Results: A significant difference between groups in the mean age of peak performance was observed (F (3, 1884) = 42,31, p &lt, 0.001). For both sexes, half-marathoners were younger than marathoners (male, 25.6 ± 3.6 years vs. 28.0 ± 3.9 years, female, 27.5 ± 4.4 years vs. 28.4 ± 4.1). Female half-marathoners in 2004 presented the highest mean age (31.1 ± 4.8 years) compared to their peers in the years 1997, 2001, 2018 and 2019, among male half-marathoners, those in 1999 presented the highest mean age when compared to 2011, 2018, and 2019. Differences between the continents of athletes’ national citizenship were observed (F (4, 1884) = 62,85,601, 0,001). Asian runners presented the lowest mean age (26.5 ± 3.7 years), while their European peers presented the highest (31.1 ± 3.9 years). No significant interaction between sex and ranking position was verified. Differences were observed between sexes for categories “4th–10th positions” and “11th–20th” (F (1, 1879) = 23,114, 0.001). Conclusions: Over the last two decades, no clear trend was observed in the changes in the age of peak performance among endurance athletes of both sexes, but, in general, female half-marathoners tended to be significantly older than their male peers.

Records from all adult patients with ≥ 1 prescription for a benzodiazepine and/or a Z-drug in 2018 were included. We calculated the prevalence of BZ and ZD user (extrapolated to the Swiss general population), the number of prescriptions and the type of provider (among each BZ and ZD only user). Multivariate logistic regression models were performed to estimate the association between drug prescription and the risk of hospitalization in different healthcare settings.Results: Of a total of 844ʹ692 patients, 95ʹ179 had ≥ 1 BZ and/or ZD prescription in 2018. The extrapolated one-year prevalence for the general Swiss population was 8.1% for a BZ prescription, 3.5% for a ZD prescription, and 10.5% for a BZ and/or ZD prescription, and continuously increased with age. The majority of the elderly (over 65 years) had ≥ 1 prescription (BZ: 51.9%; ZD: 56.9%; BZ and/or ZD: 53.5). The proportion of patients with ≥ 6 prescriptions per year was 23.1% for BZ only user and 35.2% for ZD only user. Most patients had ≥ 1 prescription from a general practitioner. Regression models showed a higher likelihood to be admitted to acute care, psychiatry, rehabilitation, or nursing home with ≥ 1 prescription for a benzodiazepine and/or a Z-drug.Conclusion: This study is the first to give a nationwide overview of the current use of benzodiazepines and Z-drugs in Switzerland based on health insurance claims data. The results revealed a remarkably high prevalence among the general Swiss population, especially in older generations. The negative consequences of heavy BZ and ZD use are a crucial public health problem, that should be addressed.Keywords: anxiolytics, sedatives, pharmacoepidemiology, health insurance claims data

Background: Proton-pump inhibitors (PPI) are among the most prescribed drugs worldwide, and a large body of evidence raises concerns about their inappropriate use. Previous estimates of inappropriate use varied due to different definitions and study populations. Aims: We aimed to measure the population-based incidence and time trends of PPI and potentially inappropriate PPI prescriptions (PIPPI) with a novel method, continuously assessing excessive cumulative doses based on clinical practice guidelines. We also assessed association of patient characteristics with PPI prescriptions and PIPPI. Methods: This was an observational study based on a large insurance claims database of persons aged >18 years with continuous claims records of ⩾12 months. The observation period was January 2012 to December 2017. We assessed the incidence and time trends of PPI prescriptions and PIPPI based on doses prescribed, defining ⩾11.5 g of pantoprazole dose equivalents during any consecutive 365 days (average daily dose >31 mg) as inappropriate. Results: Among 1,726,491 eligible persons, the annual incidence of PPI prescriptions increased from 19.7% (2012) to 23.0% (2017), ( p = Conclusions: This study provides evidence that one of the most prescribed drug groups is commonly prescribed inappropriately in the general population and that this trend is increasing. Multimorbidity and drugs with bleeding risks were strong determinants of PIPPI. Addressing PPI prescriptions exceeding guideline recommendations could reduce polypharmacy and improve patient safety.

In Switzerland, the human papillomavirus vaccination (HPVv) coverage rate lies below a desirable threshold. General practitioners (GPs) and pediatricians have been recognized as important providers of the HPVv, but there is little known about their self-attributed role and its relationship with their actual HPVv behavior. Therefore, the objective of this study was to explore the awareness, attitudes, and clinical practices of Swiss GPs and pediatricians concerning HPVv by means of a web-based questionnaire. We analyzed the responses of 422 physicians (72% GPs, 28% pediatricians). A substantial proportion of respondents considered the HPVv “absolutely essential” (54.2% of pediatricians, 30.6% of GPs). GPs indicated spending more time and effort on HPVv counseling for female rather than male patients more often compared to pediatricians (44.0% versus 13.9%, p &lt, 0.001). The weekly number of patients aged 18–26 years seen in practice (p = 0.002) and whether the HPVv was deemed “absolutely essential” (adjusted odds ratio 2.39, 95% confidence interval 1.12–5.08) were factors associated with GPs administering HPVv in their practice. Shortcomings in terms of awareness, effort in the identification of potential vaccination candidates, and the role of male patients were revealed. By addressing these gaps, Swiss primary care providers could contribute to an increase in the national HPVv coverage rate.

Low back pain (LBP) is one of the most common musculoskeletal disorders worldwide and a frequent cause for health care utilization with a high economic burden. A large proportion of diagnostic imaging in patients with LBP is inappropriate and can cause more harm than good, which in turn can lead to higher health care costs. The aim of this study was to determine characteristics and health care costs for patients with a diagnostic imaging for LBP in Switzerland. Groupe Mutuel, one of the biggest health care insurance companies in Switzerland and covering approximately 12% of the population, provided data for this analysis. Patients were identified by diagnostic imaging for the lumbar spine in 2016 or 2017. The study period was 2015–2019, that is one year before and two years after the year of imaging. Regression analysis models were used to identify patient variables associated with higher health care costs. A total of 75,296 patients (57% female, mean age: 54.5 years) were included into the study. Magnetic resonance imaging was the most commonly used diagnostic method (44.3%). Patients generated annual mean health care costs of 518,488,470 CHF (466,639,621 Euro) in the whole observation period; 640 million CHF (576 million Euro) in the index year. Overall, costs for LBP patients were 72% higher compared with the costs of no LBP patients. Our findings confirm the economic burden of LBP and highlight the importance of ongoing efforts to improve prevention, diagnostics and patient care in patients with LBP.

Trunk muscle strength and control is an important prerequisite for everyday activities among elderly people decreasing the predisposition to falls. High levels of physical exercise performed by older athletes could offer benefits to core/trunk muscle strength and postural control compared with recreational physical activities and among elderly people with lower levels of physical activity. The present study aimed to compare trunk muscle strength and postural control of older running athletes vs. older physically active adults. Participants were master road runners (RUN, n = 15, six women, 64.3 ± 3.6 years) and physically active elderly (control group, CON, n = 15, six women, 65.4 ± 5.0 years) people that were submitted to the evaluations: esthesiometer, posturography (force plate), and isokinetic test (Biodex dynamometer) of trunk muscle extension and flexion. RUN presented higher values for relative peak torque of trunk extensor muscles at 60°/s (p = 0.046) and 180°/s (p = 0.007) and relative average power during trunk extension at 60°/s (p = 0.008) and 180°/s (p = 0.004) compared to CON. CON had a higher medial-lateral oscillation speed of the center of pressure in the stable condition with eyes closed (p = 0.004) compared to RUN. RUN presented higher isokinetic torque of extensor trunk muscles and better postural control than CON. This supposedly could help with postural control and balance and contribute to the prevention of falls among the elderly. The practice of running systematically by master athletes may partially explained our findings.

Searching for potential relations between changes in 25(OH)D concentration and in physical fitness is an interesting scientific topic. Thus, the main purpose of this study was to investigate the changes in serum concentrations of 25(OH)D in young football players in conjunction with indicators determining bone resorption and physical fitness. A total of 35 young soccer players were tested during the autumn competition period. Biochemical analysis of blood, aerobic capacity, running speed and power tests (Wingate test, squat jump, counter movement jump) were carried out at the beginning and at the end of the competition period. Significant decrements in concentration of 25(OH)D from 33.9 ± 5.87 to 23.7 ± 5.58 ng/mL were noted after the analyzed competition period. There were no significant changes in aerobic capacity along the competition period. Significant improvements were observed in 10 m sprint, 30 m sprint (p &lt, 0.001), maximal power (p = 0.011) and total work capacity (p = 0.024). We found that the effect of changes in the players’ physical fitness does not occur in relation to 25 OH(D) concentration but occurs when these changes are analyzed as a function of the duration of the observation period. Changes in physical fitness of soccer players are determined by other factors then 25(OH)D concentration.

This systematic review with meta-analysis was conducted to assess the effects of small-sided games (SSG)-based training programs on bone mineral density (BMD) in untrained adults. The data sources utilized were Cochrane, Embase, Medline (PubMed), Scopus, SPORTDiscus, and Web of Science. The study eligibility criteria were: (i) untrained adults (>18 years old) of any sex, with or without a noncommunicable disease; (ii) SSG-based programs with a minimum duration of four weeks and no restrictions regarding frequency (number of sessions per week); (iii) passive or active control groups; (iv) pre-post values of BMD; (v) only randomized controlled trials; and (vi) only original and full-text studies written in English. The database search initially yielded 374 titles. From those, nine articles were eligible for the systematic review and meta-analysis. The age of included population varied from a minimum of 20 and a maximum of 71 years old. Non-significant differences between SSG and passive and active control groups on total BMD (ES = 0.14; p = 0.405 and ES = 0.28; p = 0.05, respectively). Meanwhile, significant differences in favor of SSGs vs. passive and control groups were detected, evidencing an improvement of BMD in lower limbs of the adult population for both sexes (ES = 0.26; p = 0.05 and ES = 0.28; p = 0.156, respectively). As conclusions, SSGs can be used as a non-pharmacological alternative to increase the BMD in the lower limbs despite having no significant impact on total body BMD. Careful generalization should be done of the level of heterogeneity.

Acute low back pain (LBP) is one of the most prevalent diseases worldwide. Since there is evidence of excessive prescriptions of analgesics, i.e., opioids, the aim of this study was to describe the use of pain medications in patients with LBP in the Swiss primary care setting. A retrospective, observational study was performed using medical prescriptions of 180 general practitioners (GP) during years 2009–2020. Patterns of pain medications (nonsteroidal anti-inflammatory drugs (NSAIDs), paracetamol, and opioids) as well as co-medications were analyzed in patients with a LBP diagnosis. Univariable and multivariable regression analyses assessed GP and patient characteristics associated with the prescription of pain medication. Patients included were 10,331 (mean age 51.7 years, 51.2% female), 6449 (62.4%) received at least one pain medication and of these 86% receive NSAIDs and 22% opioids. GP characteristics (i.e., self-employment status) and patient characteristics (male gender and number of consultations) were associated with significantly higher odds of receiving any pain medication in multivariable analysis. 3719 patients (36%) received co-medications. Proton-pump-inhibitors and muscle relaxants were the most commonly used co-medications. In conclusion, two-thirds of LBP patients were treated with pain medications. Prescribing patterns were conservative, with little use of strong opioids and co-medications.

Vitamin B12 is often used to improve cognitive function, depressive symptoms, and fatigue. In most cases, such complaints are not associated with overt vitamin B12 deficiency or advanced neurological disorders and the effectiveness of vitamin B12 supplementation in such cases is uncertain. The aim of this systematic review and meta-analysis of randomized controlled trials (RCTs) is to assess the effects of vitamin B12 alone (B12 alone), in addition to vitamin B12 and folic acid with or without vitamin B6 (B complex) on cognitive function, depressive symptoms, and idiopathic fatigue in patients without advanced neurological disorders or overt vitamin B12 deficiency. Medline, Embase, PsycInfo, Cochrane Library, and Scopus were searched. A total of 16 RCTs with 6276 participants were included. Regarding cognitive function outcomes, we found no evidence for an effect of B12 alone or B complex supplementation on any subdomain of cognitive function outcomes. Further, meta-regression showed no significant associations of treatment effects with any of the potential predictors. We also found no overall effect of vitamin supplementation on measures of depression. Further, only one study reported effects on idiopathic fatigue, and therefore, no analysis was possible. Vitamin B12 supplementation is likely ineffective for improving cognitive function and depressive symptoms in patients without advanced neurological disorders.

The present study investigated pre-race preparation of a large sample of recreational runners competing in different race distances (e.g., shorter than half-marathon, half-marathon, marathon and ultra-marathon). An online questionnaire was used and a total of 3,835 participants completed the survey. Of those participants, 2,864 (75%) met the inclusion criteria and 1,628 (57%) women and 1,236 (43%) men remained after data clearance. Participants were categorized according to race distance in half-marathon (HM), and marathon/ultra-marathon (M/UM). Marathon and ultra-marathon data were pooled since the marathon distance is included in an ultra-marathon. The most important findings were (i) marathon and ultra-marathon runners were more likely to seek advice from a professional trainer, and (ii) spring was most commonly reported across all subgroups as the planned season for racing, (iii) training volume increased with increasing race distance, and (iv) male runners invested more time in training compared to female runners. In summary, runners competing in different race distances prepare differently for their planned race.Clinical Trial Registration:www.ClinicalTrials.gov, identifier ISRCTN73074080.

Predictive resting metabolic rate (RMR) equations are widely used to determine athletes’ resting energy expenditure (REE). However, it remains unclear whether these predictive RMR equations accurately predict REE in the athletic populations. The purpose of the study was to compare 12 prediction equations (Harris-Benedict, Mifflin, Schofield, Cunningham, Owen, Liu’s, De Lorenzo) with measured RMR in Turkish national team athletes and sedentary controls. A total of 97 participants, 49 athletes (24 females, 25 males), and 48 sedentary (28 females, 20 males), were recruited from Turkey National Olympic Teams at the Ministry of Youth and Sports. RMR was measured using a Fitmate GS (Cosmed, Italy). The results of each 12 prediction formulas were compared with the measured RMR using paired t-test. The Bland-Altman plot was performed to determine the mean bias and limits of agreement between measured and predicted RMRs. Stratification according to sex, the measured RMR was greater in athletes compared to controls. The closest equation to the RMR measured by Fitmate GS was the Harris-Benedict equation in male athletes (mean difference -8.9 (SD 257.5) kcal/day), and Liu’s equation [mean difference -16.7 (SD 195.0) kcal/day] in female athletes. However, the intra-class coefficient (ICC) results indicated that all equations, including Harris-Benedict for male athletes (ICC = 0.524) and Liu’s for female athletes (ICC = 0.575), had a moderate reliability compared to the measured RMR. In sedentary subjects, the closest equation to the measured RMR is the Nelson equation in males, with the lowest RMSE value of 118 kcal/day [mean difference: 10.1 (SD 117.2) kJ/day], whereas, in females, all equations differ significantly from the measured RMR. While Nelson (ICC = 0.790) had good and Owen (ICC = 0.722) and Mifflin (calculated using fat-free mass) (ICC = 0.700) had moderate reliability in males, all predictive equations showed poor reliability in females. The results indicate that the predictive RMR equations failed to accurately predict RMR levels in the participants. Therefore, it may not suitable to use them in determining total energy expenditure.

Aims Heart failure is one of the leading causes of morbidity and mortality worldwide, but little is known on heart failure epidemiology and treatment in primary care. This study described patients with heart failure treated by general practitioners, with focus on drug prescriptions and especially on the only specific treatment for heart failure with reduced ejection fraction, namely sacubitril/valsartan. Methods and results This was a retrospective cross‐sectional study using data from an electronic medical record database of Swiss general practitioners from 2016 to 2019. Multilevel logistic regression was used to find determinants of sacubitril/valsartan prescription; odds ratios (ORs) and 95% confidence intervals (CIs) were reported. We identified 1288 heart failure patients (48.5% women; age: median 85 years, interquartile range 77–90 years) by means of diagnosis code, representing 0.5% of patients consulting a general practitioner during the observation period. About 73.6% received a renin–angiotensin–aldosterone system inhibitor, 67.8% a beta‐blocker, 34.6% a calcium channel blocker, 86.1% a diuretic, and 40.1% another cardiac drug. Sacubitril/valsartan was prescribed in 6% predominantly male patients (OR 2.10, CI 1.25–3.84), of younger age (OR 0.59 per increase in 10 years, CI 0.49–0.71), with diabetes mellitus (OR 1.76, CI 1.07–2.90). The recommended starting dose for sacubitril/valsartan was achieved in 67.1% and the target dose in 28.6% of patients. Conclusions Prevalence of heart failure among patients treated by general practitioners was low. Considering the disease burden and association with multimorbidity, awareness of heart failure in primary care should be increased, with the aim to optimize heart failure therapy.

The aim of this study was to evaluate and compare the hamstring (H) and quadriceps (Q) strength, bilateral difference and balance ratios in female soccer players. Ninety-three athletes from three age groups: under 13 (U13), 15 (U15) and 18 (U18) participated in the study performing isokinetic tests to measure peak torque, total work, average power and torque at 30o of thigh muscles. Conventional strength balance ratios, angle-specific balance ratio and bilateral strength difference were evaluated. There was bilateral strength difference for extensor muscles total work (p = 0.02) in U13 and flexor muscles peak torque (p = 0.02) in U15. All variables were superior in U15 than U13 (p

WHAT IS KNOWN ON THE SUBJECT, AND WHAT THE STUDY ADDS: The number of home visits by general practitioners (GPs) has decreased in recent years, in contrast to the increasing number of frail and older patients in western countries. Current data on GP home visit numbers and rates are lacking for Switzerland. Our study provides new data on GP home visit numbers and rates, and their associations with patient characteristics. AIM Our study aimed at investigating the time trend of GP home visits to older patients from 2014 to 2018 in Switzerland, and associations between GP home visits and patient characteristics including healthcare utilisation and living situation. METHODS Retrospective cross-sectional study of insurance claims data from 2014 to 2018 among patients aged ≥65 years (Nextrapolated = 2,095,102; Nraw = 339,301). We compared patient characteristics between patients with and without GP home visits using descriptive statistics. We performed logistic regression analyses to detect associations between patient characteristics and GP home visits, including subgroups of patients aged ≥80 and patients living in a nursing home. Regression models were adjusted for age and sex. RESULTS The yearly GP home visit rate declined from 10.7% to 9.3% from 2014 to 2018 (p

The aim of this study was to analyze the variations of acute load (AL), acute: chronic workload ratio (ACWR), training monotony (TM), and training strain (TS) of accelerometry-based GPS measures in players who started in three matches (S3M), two matches (S2M), and one match (S1M) during congested weeks. Nineteen elite professional male players from a Portuguese team (age: 26.5 &plusmn, 4.3 years) were monitored daily using global positioning systems (GPSs) over a full season (45 weeks). Accelerometry-derived measures of high metabolic load distance (HMLD), high accelerations (HA), and high decelerations (HD) were collected during each training session and match. Seven congested weeks were classified throughout the season, and the participation of each player in matches played during these weeks was codified. The workload indices of AL (classified as ACWR, TM, and TS) were calculated weekly for each player. The AL of HMLD was significantly greater for S2M than S1M (difference = 42%, p = 0.002, d = 0.977) and for S3M than S1M (difference = 44%, p = 0.001, d = 1.231). Similarly, the AL of HA was significantly greater for S2M than S1M (difference = 25%, p = 0.023, d = 0.735). The TM of HD was significantly greater for S2M than S3M (difference = 25%, d = 0.774). Accelerometry-based measures were dependent on congested fixtures. S2M had the greatest TS values, while S3M had the greatest TM.

Therefore, reported prevalence varies in the literature due to different case definitions, methodological, and environmental factors.Objectives: The purpose of our cross-sectional study was to estimate the prevalence of CRSWD in the general population of Cyprus and to suggest clinical parameters for the assessment of atypical sleep schedules. The estimation was carried out by introducing normal preset sleep time limits, according to the imposed local environment and by administering well-established questionnaires for symptoms and consequence dysfunction, as objective evaluation tools.Methods: In a nationwide epidemiological survey, 4118 Cypriot adult participants, selected and stratified to represent the general population, were interviewed on sleep habits and complaints by computer-assisted telephone interviewing (CATI). In the second stage, 250 adults were randomly selected from the initial representative sample, for a CRSWD assessment. According to the proposed diagnostic criteria, patients were interviewed about sleepiness and/or insomnia, and daytime dysfunction (fatigue, anxiety, and depression). They were also assessed by a weekly sleep diary for sleep schedules. Finally, all participants underwent a Type III Sleep Study, to rule out obstructive sleep apnea.Results: From 195 enrolled participants (response rate 78%), 25 individuals (12.8%) met the criteria for CRSWD. The two most prevalent disorders were delayed sleep-wake phase disorder (DSWPD) (10pts, 5.1%) and shift work sleep disorder (SWD) (13, 6.7%). Less prevalent disorders included irregular sleep-wake rhythm disorder (ISWRD) (1, 0.5%) and advanced sleep-wake phase disorder (ASWPD) (1, 0.5%).Conclusions: According to our data, CRSWDs are common in the general population of Cyprus, especially DSWPD and SWD. Affected individuals usually suffer from sleep deprivation and complain about insomnia, sleepiness and depression.Keywords: circadian sleep wake phase disorders, prevalence, sleep deprivation, guidelines

BackgroundThe effect of vegan diets on metabolic processes in the body is still controversial in ultra endurance athletes. The study aims to determine gut microbiome adaptation to extreme exercise according to vegan or omnivore diet consumed in ultra-marathoners. We also seek to evaluate long-term vegan diets’ effects on redox homeostasis, and muscle fatigue, and assess energy availability.MethodsSeventy participants will be assigned to the study, including 35 vegan ultra-marathoners and 35 omnivores competing in the Sri-Chinmoy ultra marathon race. Research data will be collected from the participants at four steps (three visits to the research laboratory and the race day) throughout the study. At the first visit (seven days before the race), fecal samples, and anthropometric measurements will be collected. Body composition will be measured using DXA. Participants will be informed about keeping detailed food records and will be asked to record their diet data and activity logs during the entire study period. At second visit, maximum oxygen consumption will be measured on treadmill. On race day, blood samples will be collected immediately before, and 0. min, 2 hours, and 24 hours after the race. Body weight will be measured before and after the race. The blood and fecal samples will be stored at -80 C until analysis. Plasma malondialdehyde, reactive oxygen metabolites, total antioxidant capacity, Heatshockprotein-70, and serum Orosomucoid-1 will be analyzed in blood samples. Fecal samples will be analyzed with shotgun metagenomic analysis and interpreted using bioinformatics pipeline (HumanN2). Statistical tests will be analyzed using SPSS version 23.0 and R Software.DiscussionStudy findings will determine the effects of the vegan diet on sports performance, revealing the multiple interactions between host and gut microbiome at the whole metagenomic level. Additionally, results will show the possible adaptation throughout the race by analyzing blood and fecal samples. Furthermore, by assessing energy availability and determining host-metabolite crosstalk for ultra-endurance athletes, possible nutritional deficiencies can be identified. Thus, advanced nutritional strategies can be developed based on metabolic needs.Trial registrationCurrent controlled trials, ISRCTN registry 69541705. Registered on 8 December 2019.

Aims In some healthcare systems, physicians are allowed to dispense drugs; in others, drug-dispensing is restricted to pharmacists. Whether physician-dispensing affects patient health is unknown. Thus, we aimed to investigate associations between physician-dispensing and clinical and process measurements in patients with selected long-term conditions indicating increased cardiovascular risk. Methods Retrospective cross-sectional study in 2018 based on data from electronic medical records of 22405 patients (73.6% physician-dispensing) in Switzerland with medications for diabetes mellitus, arterial hypertension, or lipid-related disorders. We used multilevel regression models to determine the associations between physician-dispensing and clinical measurements (glycated hemoglobin [HbA1c], systolic blood pressure [sBP], low-density lipoprotein cholesterol [LDL-C]) or process measurements (number of annual clinical measurements, consultations, and drug prescriptions). Results Median (interquartile range) HbA1c value was 6.8% (6.3-7.5) both for the physician-dispensing and pharmacist-dispensing group, sBP was 137 (126-150) and 136 mmHg (126-149), and LDL-C was 2.3 (1.8-3.0) and 2.5 mmol/L (1.9-3.2). After adjustments, the physician-dispensing group had 4% lower LDL-C levels (p = 0.041), 12% more frequent HbA1c measurements (p = 0001), 16% higher annual consultation rates (p < 0.05 for all conditions), and equal number of different drugs, compared to the pharmacist-dispensing group. Conclusions We found no relevant differences in selected clinical measurements between physician- and pharmacist-dispensing, and mixed results in process measurements. Our results do not indicate that one drug-dispensing channel is superior to the other.

Introduction: Little information exists in the general population whether clinical presentation phenotypes of obstructive sleep apnea (OSA) differ in terms of sleep quality and comorbidities.Aim: The purpose of our study was to assess possible differences between symptomatic and asymptomatic OSA patients concerning syndrome's severity, patients' sleep quality, and comorbidities.Subjects and methods: First, in a nationwide, stratified, epidemiological survey, 4,118 Cypriot adult participants were interviewed about sleep habits and complaints. In the second stage of the survey, 264 randomly selected adults underwent a type III sleep study for possible OSA. Additionally, they completed the Greek version of Pittsburgh Sleep Quality Index (Gr-PSQI), Epworth Sleepiness Scale (ESS), Athens Insomnia Scale (AIS), and Hospital Anxiety and Depression Scale (HADS).Results: From 264 enrolled participants, 155 individuals (40 females and 115 males) were first diagnosed with OSA. Among these 155 patients, 34% had ESS ≥ 10 and 49% AIS ≥ 6. One or both symptoms present categorized the individual as symptomatic (60%) and neither major symptom as asymptomatic (40%). There were no significant statistical differences (SSDs) between the two groups (symptomatic–asymptomatic) with regard to anthropometrics [age or gender; neck, abdomen, and hip circumferences; and body mass index (BMI)]. The two groups had no differences in OSA severity—as expressed by apnea–hypopnea index (AHI), oxygen desaturation index (ODI), and mean oxyhemoglobin saturation (SaO2)—and in cardiometabolic comorbidities. Symptomatic patients expressed anxiety and depression more often than asymptomatics (p < 0.001) and had poorer subjective sleep quality (Gr-PSQI, p < 0.001). According to PSQI questionnaire, there were no SSDs regarding hours in bed and the use of sleep medications, but there were significant differences in the subjective perception of sleep quality (p < 0.001), sleep efficiency (p < 0.001), duration of sleep (p = 0.001), sleep latency (p = 0.007), daytime dysfunction (p < 0.001), and finally sleep disturbances (p < 0.001).Conclusion: According to our data, OSA patients reporting insomnia-like symptoms and/or sleepiness do not represent a more severe phenotype, by the classic definition of OSA, but their subjective sleep quality is compromised, causing a vicious cycle of anxiety or depression.

Introduction: Obstructive sleep apnea (OSA) and its cardiometabolic alterations are closely associated with visceral obesity. Patients with OSA frequently present with symptoms of depression and anxiety. Although these subjective symptoms of OSA are the result of complex biological dysregulation, it remains unclear if they have a direct effect on the dysfunction of adipose tissue.Methods: In a pilot, prospective, randomized study, we evaluated 10 recently diagnosed male patients with severe OSA by full polysomnography (PSG) and 4 male non-apneic subjects matched for age and body mass index (BMI) with abdomen adipose tissue biopsies. Subjects with diabetes/prediabetes and cardiovascular and psychiatric diseases and who are current smokers were excluded. All patients underwent anthropometric measurements and completed the following questionnaires: Epworth Sleepiness Scale (ESS), Fatigue Severity Scale (FSS), and Hospital Anxiety and Depression Scale (HADS-A and HADS-D). Fasting venous blood samples were collected on the day after PSG, between 8:00 and 9:00 a.m., after an overnight fast. Fat biopsies were performed at the same time periods and adipose tissue samples of 300 mg were obtained from abdominal fat. Fat cell size, extent of fibrosis, vascularity, leukocyte common antigen inflammatory infiltration, and tissue macrophage accumulation were microscopically evaluated.Results: The mean age of the group was 47.4 +/- 13.8 years, with mean BMI of 35.8 +/- 4.8 kg/m(2) and mean apnea-hypopnea index of 79.4 +/- 46.1 events per hour of sleep (severe OSA). HADS-A and HADS-D scores were 5.8 +/- 2.3 (3.0-8.0) and 4.7 +/- 2.3 (2.0-8.0), respectively. HADS-A score correlated positively with macrophage accumulation in fat biopsy (r = 0.82, p = 0.047), whereas ESS, FSS, and HADS-D did not. Severity of fibrosis correlated largely with waist circumference (r = -0.66, p = 0.038) and neck circumference (r = -0.790, p = 0.006). Respiratory events correlated negatively with the extent of vascularization of adipose tissue (r = -0.614, p = 0.05).Conclusions: In the preliminary results of our pilot study, we assessed that the symptoms of anxiety mainly contribute to macrophage accumulation, whereas the increased number of respiratory events reduces the extent of vascularization in visceral fat in OSA. Based on this observation, further larger studies are required to verify if anxious OSA patients are more vulnerable to the metabolic manifestations of the syndrome.

Background and objectives: The COVID-19 outbreak has become a major health and economic crisis. The World Health Organization declared it a pandemic in March 2020, and many sporting events were canceled. Materials and Methods: We examined the effects of the COVID-19 pandemic on endurance and ultra-endurance running (UER) and analyzed finishes and events during the COVID-19 pandemic (observation period March 2020&ndash, October 2020) to the same time period pre-COVID-19 outbreak (March 2019&ndash, October 2019). Results: Endurance finishes decreased during the pandemic (459,029 to 42,656 (male: 277,493 to 25,582, female 181,536 to 17,074, all p &lt, 0.001). Similarly, the numbers of endurance events decreased (213 vs. 61 events, p &lt, 0.001). Average marathon finishing times decreased during the pandemic in men (5:18:03 &plusmn, 0:16:34 vs. 4:43:08 &plusmn, 0:25:08 h:min:s (p = 0.006)) and women (5:39:32 &plusmn, 0:19:29 vs. 5:14:29 &plusmn, 0:26:36 h:min:s (p = 0.02)). In UER, finishes decreased significantly (580,289 to 110,055, 0.001) as did events (5839 to 1791, 0.001). Popular event locations in United States, France, UK, and Germany decreased significantly (p &lt, 0.05). All distance and time-limited UER events saw significant decreases (p &lt, 0.05). Conclusions: The COVID-19 pandemic has had a significant effect on endurance and UER, and it is unlikely that running activities return to pre-pandemic levels any time soon. Mitigation strategies and safety protocols should be established.

The primary nutritional challenge facing endurance runners is meeting the nutrient requirements necessary to optimize the performance and recovery of prolonged training sessions. Supplement intake is a commonly used strategy by elite and recreational distance runners to meet nutritional recommendations. This study was conducted to investigate the patterns of supplement intake among different groups of distance runners and the potential association between supplement intake and sex, age, running and racing experiences. In a cross-sectional design, from a total of 317 runners participating in this survey, 119 distance runners were involved in the final sample after data clearance, assigned into three groups of 10-km runners (n = 24), half-marathoners (n = 44), and (ultra-)marathoners (n = 51). Personal characteristics, training and racing experiences, as well as patterns of supplement intake, including type, frequency, and dosage, were evaluated by questionnaire. Food Frequency Questionnaire was implemented to assess macronutrient intake. ANOVA and logistic regression were used for statistical analysis. While 50 % of total distance runners reported consuming supplements regularly, no differences between distance groups in consumption of carbohydrate/protein, mineral, or vitamin supplements were observed (p > 0.05). In addition, age, sex, running and racing experience showed no significant association with supplement intake (p > 0.05). Vitamin supplements had the highest intake rate in runners by 43 % compared to minerals (34 %) and carbohydrate/protein supplements (19 %). The present findings provide a window into the targeted approaches of long-distance runners as well as their coaches and sport nutrition specialists when applying and suggesting sustainable nutritional strategies for training and competition.

Background The present study assessed the prevalence of non-contact muscle injuries of the lower limbs, including hamstring injuries, in professional Russian soccer players who regularly perform Salah, an obligatory Muslim prayer performed 5 times a day. Methods Using a retrospective cohort study design, 68 professional male soccer players (excluding goalkeepers), 34 of whom were Muslims regularly performing Salah (exposure group) and 34 were randomly chosen non-Muslim players (control group), were included in the study. The groups were similar in their playing leagues, field positions, age (27 ± 3.1 vs 28 ± 4.2 years), and body mass index (22 ± 1.2 vs 23 ± 0.92 kg/m2). Results The incidence of hamstring injury was significantly lower in the exposure group (2 vs 14, p = 0.0085). A declining trend for the number of muscle injuries (either hamstring or not) was observed in the exposure group (11 vs 27, p = 0.0562). Two players in the exposure group and 11 in the control group (p = 0.0115, OR 0.1307, 95% CI 0.0276 to 0.5698) suffered a hamstring injury, with no statistically significant difference in the occurrence of other injuries. The total amount of the training and play days missed because of hamstring and other muscle injuries was significantly lower in the exposure group (24 vs 213 days, p = 0.0043, and 200 vs 344 days, p = 0.0066, respectively). Conclusion The prevalence of non-contact muscle injuries, including hamstring injuries, was lower in professional Russian soccer players who regularly performed Salah.
