Objective This study aimed to determine the feasibility of using a wrist-based fitness tracking device to assess sleep among Obstetrics and Gynecology (OBGYN) trainees who engaged in a yoga-based wellness program. We also sought to evaluate the effects of yoga on sleep. Study Design A quality improvement initiative consisting of an 8-week wellness program of weekly yoga classes, nutrition, and physical challenges was implemented for OBGYN residents and Maternal–Fetal Medicine fellows. The Polar A370 fitness tracker device was provided and synced to the Polar Flow for Coach program for inclusion. Data obtained included total and restful sleep from each night the device were worn. Pre- and post-assessment of the Pittsburg Sleep Quality Index (PSQI) were compared. Linear mixed models were used to estimate and test the effect of yoga on sleep while controlling for on-call shifts. Results Of the 15 participants who synced their device, 13 (87%) were included for analysis. Sleep data from 572 nights were analyzed. The mean (SD) total sleep was 434.28 (110.03) minutes over the 8 weeks. A minimum of 7 hours (420 minutes) of total sleep occurred 59.3% of the time. After controlling for Friday or Saturday night on-call, those who attended yoga class had a significantly greater total sleep (yoga: 425.14 minutes [41.89], no yoga: 357.33 [43.04] minutes; p = 0.04). There was no significant change in the mean global PSQI score after the program (pre: 5.0 [1.6], post: 5.1 [2.5], p = 0.35). Conclusion Wearable fitness monitors provide insight into sleep patterns displayed during training and can serve as a tool to identify those who are sleep deprived and assist in the evaluation of trainee wellness. Training programs are encouraged to provide access to yoga and mindfulness interventions to improve sleep and possibly clinical performance. Key Points

Hiking is a very popular outdoor activity, and has led to an exponential increase in the number of visitors to natural spaces. The objective of this study was to analyze the circulation pattern of visitors to the Caminito del Rey trail, based on the three zones into which the trail can be divided. The sample consisted of 1582 hikers distributed into three different profiles. Of these, 126 utilized an eye-tracking device during the hike, while, for the rest (1456), only their travel speed along the trail was recorded. The use of eye tracking devices identified a greater number of interesting landscapes located in zones 1 and 3 of the trail, and it was observed that the mean travel speed was greater for zone 2 (42.31 m/min) (p < 0.01). Additionally, when the three different visitor profiles were analyzed, significant differences were found between the mean travel speeds according to sectors (p < 0.05). This information is crucial for more efficient management of the trail, as it allows for the development of measures to control and regulate the flow of visitors according to zone, and the design of additional strategies to increase the awareness of the hiker about specific areas of the hike.

Background: Retrospective cohort study evaluating long term keratoconus progression amongst cross-linking (CXL) treated pediatric patients in the treated and the fellow untreated eyes. Methods: Data on 60 eyes of 30 patients, 18 years old or younger, who underwent CXL in at least one eye was collected and analyzed. Follow-up measurements taken from the treated and untreated eye up to 7 years after CXL treatment, were compared to baseline measurements. Parameters included uncorrected distance visual acuity (UCDVA), best-corrected spectacle visual acuity (BCSVA), manifest refraction, pachymetry, corneal tomography, and topography. Results: Mean age of patients was 16 ± 2.1 years. For the treated eyes, during follow-up period mean UCDVA had improved (from 0.78 ± 0.22 at baseline to 0.58 ± 0.26 logMAR at 7 years; p = 0.13), as well as mean BCSVA (from 0.23 ± 0.107 at baseline to 0.172 ± 0.05 logMAR at 7 years; p = 0.37). The mean average keratometry showed a significant flattening (from 49.95 ± 4.04 to 47.94 ± 3.3 diopters (D); p < 0.001), However there was no change in the mean maximal keratometry. The mean minimal corneal thickness (MCT) showed a significant mild reduction of 26 µm ( p = 0.006). Although statistically insignificant, the mean manifest cylinder was also reduced to 2D ( p = 0.15). During the follow-up period, eight untreated eyes (26.6%) deteriorated and underwent CXL, while only one treated eye (3.33%) required an additional CXL. Conclusion: CXL is a safe and efficient procedure in halting keratoconus progression in the pediatric population, the fellow eye needs to be carefully monitored but only a 25% of the patients will require CXL in that eye during a period of 7 years.

The Estonian NEO‐FFI was administered to 2650 Estonian adolescents (1420 girls and 1230 boys) aged from 12 to 18 years and attending 6th, 8th, 10th, or 12th grade at secondary schools all over Estonia. Although the mean levels of personality traits of Estonian adolescents were quite similar to the respective scores of Estonian adults, there was a developmental gap in Agreeableness and Conscientiousness. Three of the five personality dispositions demonstrated a modest cross‐sectional change in the mean level of the trait scores: the level of Openness increased and the levels of Agreeableness and Conscientiousness decreased between 12 and 18 years of age. Although the five‐factor structure of personality was already recognizable in the sample of 12‐year‐old children, it demonstrated only an approximate congruence with the adult structure, suggesting that not all children of that age have developed abilities required for observing one's own personality dispositions and for giving reliable self‐reports on the basis of these observations. The self‐reported personality trait structure matures and becomes sufficiently differentiated around age 14–15 and grows to be practically indistinguishable from adult personality by the age of 16. Personality of adolescents becomes more differentiated with age: along with the growth of mental capacities the correlations among the personality traits and intelligence become smaller.

Abstract. A dramatic increase in the frequency and intensity of floods due to the Niger River in the city of Niamey (Niger) has been observed in the last decade. Previous studies highlighted the role of the land use changes on the flood increase since 1970s. In the last decade, observations have raised the issue of a possible increase in extreme rainfall in the Sahel, which may have caused the recent and extreme floods in Niamey in 2010, 2012 and 2013. The study focuses on the 125 000 km2 basin between Ansongo and Niamey. This is the drainage area of the monsoon rainfall that leads to the rapid flow rise occurring between June and October. To understand the possible role of rainfall in flood intensification, satellite rainfall estimate is attractive in a region where the operational gauge network is sparse. This paper analyses the evolution of the Niger hydrograph in Niamey based on discharge observations, hydrological modelling and the satellite product PERSIANN-CDR, over the 1983–2013 period. PERSIANN-CDR is first compared with four other rainfall products. The salient features of the observed changes, i.e. a marked change in the mean decadal hydrograph, is well mimicked by the simulations, implying that rainfall is the first driver to the observed changes. The increase of flooded years over the period is also well reproduced but with some uncertainties in the exact number of flood days per year.

Purpose: This paper describes a self-contained model of integrated clinical experiences (ICEs) that take place during the academic portion of an entry-level physical therapist education program in a campus onsite clinic. Description of Model: Students participate in ICEs for three consecutive semesters. Students provide pro bono physical therapy services to individuals with impairments, functional limitations, or changes in physical function resulting from a variety of health conditions. In addition, students participate in an exercise/wellness program for individuals who wish to improve or maintain their current levels of fitness. The first ICE consists of second-year students observing/assisting third-year students in the onsite clinic with basic patient care skills and participation in an exercise/wellness program. Students in the second and third ICEs provide ongoing one-on-one skilled therapy for individuals with neurological or musculoskeletal diagnoses. Results: Feedback obtained from onsite clinical instructors, core academic faculty, students, and patients receiving care in the onsite clinic through group debriefings, questionnaires, and interviews is used to assess students’ readiness for full-time internships and effectiveness of the ICEs. The feedback reveals that the ICEs are meeting their intended goals. Category ratings in the “red flag” areas of the Clinical Performance Instrument (CPI) are consistently above expected levels for students completing their first full-time clinical internship. In addition, patients receiving care in the onsite clinic report a high level of satisfaction with the care provided. Conclusion/Possible Recommendations: This model provides students with an opportunity to gain clinical confidence in a realistic setting while reinforcing concepts presented in academic coursework. Providing ICEs on campus decreases reliance on clinical facilities and allows for academic program oversight of the quality of the learning experiences and early identification of students who have deficits in clinical skills and/or academic knowledge. The learning experiences provided in the onsite clinic give students a transitional experience that helps them benefit more fully from full-time internships. A potential challenge to this model is finding the space and financial resources needed to make it viable.

&lt;p&gt;Small variations in the mean state of the atmosphere can cause large changes in the frequency of extreme events. In order to deepen and extend previous results in time, in this work we analyzed the linear relationship between extreme and mean temperature (&amp;#932;) on a climate change scale in Argentina. Two monthly extreme indices, cold nights (TN10) and warm days (TX90), were calculated based on the quality-controlled daily minimum and maximum temperature data provided by the Argentine National Meteorological Service from 58 conventional weather stations located over Argentina in the 1977&amp;#8211;2017 period. Subsequently, we evaluated the relationship between the linear trends of extremes and mean temperature on a seasonal basis (JFM, AMJ, JAS, and OND). Student's T-test was performed to analyze their statistical significance at 5%. Firstly, positive (negative) and significant linear regressions were found between TX90 (TN10) trends and mean temperature trends for the four studied seasons. Therefore, an increase in the &amp;#932;-trend maintains a linear relationship with significant increase (decrease) of warm days (cold nights). Moreover, we found that JFM was the one with the highest coefficient of determination (0.602 for hot extremes and 0.511 for cold extremes), implying that 60.2% (51.1%) of the TX90 (TN10) trend could be explained as a function of the &amp;#932;-trend by a linear regression. In addition, in the JFM (OND) quarter, the TX90 index increased by 7.02 (6.02) % of days each with a 1 &amp;#186;C increase in the mean temperature. Likewise, the TN10 index decreased by 4.94 (and 4.99) % of days from a 1&amp;#186;C increase in the mean temperature for the JFM (AMJ) quarter. Finally, it is worthwhile to highlight the uneven behavior between hot and cold extremes and the mean temperature. Specifically, it was observed that the slopes of the linear regression calculated for the TX90 index and &amp;#932;&amp;#160;presented a higher absolute value than those registered for the TN10 index and &amp;#932;. Therefore, a change in the mean temperature affects hot extremes to a greater extent than cold ones in Argentina.&lt;/p&gt;

AbstractObjective:We analysed the impact of the national general truck drivers’ strike on the availability, variety and price of foods sold by a food supply centre.Design:Descriptive study using secondary data to examine the percentage change in the mean price of fruits, vegetables and eggs before, during and after the strike. The strike in Brazil lasted 10 d from 21 to 30 May 2018. The drivers were on strike in order to make diesel oil tax-free and to obtain better working conditions.Setting:The food supply centre, named CEASA-Minas Grande BH, was located in the metropolitan area of a Brazilian city.Participants:We examined twenty types of foods.Results:After 10 d, there was a ~30 % reduction in the availability of all types of foods and prices increased. Foods with the highest price increases included cabbage (233·3 %), potatoes (220·0 %), papaya (160·0 %) and oranges (78·6 %). At the end of the strike, we observed reductions in the price of eggs, fruits, vegetables, roots and tubers; however, some foods remained more expensive than before the strike, including chayote (203·2 % higher), cucumber (66·7 % higher) and potatoes (60·0 % higher).Conclusions:The general truck drivers’ strike was correlated with a reduction in the availability of food and, consequently, increases in price and possibly restrictions on access. The strike demonstrated the dependence of metropolises on road transportation and the conventional market. We speculate that initiatives aiming to shorten the food supply chain and promote food sovereignty and resilience of the supply circuits could be important.

1. The effect of the sympathetic innervation on the bladder detrusor muscle was assessed in pentobarbitone-anesthetized cats by measuring the changes in bladder wall tension that occurred during sympathetic ganglion blockade after filling the bladder at a natural rate. 2. At a point 60% of the way through the continence process, systemic sympathetic blockade was produced by intravenous trimethaphan, and selective blockade of postganglionic hypogastric nerve activity was produced by application of trimethaphan to the exposed inferior mesenteric ganglia. The level of blockade was monitored with an in-continuity hypogastric nerve recording. 3. During both systemic and selective ganglion blockade, there was an increase in baseline transmural bladder pressure and a decrease in the amplitude of nonmicturating contractions. 4. Although there was no change in the mean level of transmural bladder pressure during either systemic or selective blockade, there was a significant increase in the mean level of bladder wall mechanoreceptor discharge, suggesting that before the blockade sympathoinhibitory effects were greater than sympathoexcitatory effects. 5. Measurement of bladder wall mechanoreceptor discharge before and during ganglion blockade revealed a net sympathoinhibitory influence on the level of bladder wall tension under natural filling conditions. These results confirm that the detrusor muscle of the feline bladder is under both sympathoinhibitory and sympathoexcitatory influences for a significant portion of the continence process.

Induced Changes

Desoxyribonucleic acid (DNA) was carefully prepared in a highly purified, undenatured form from beef brain, beef liver and rabbit liver. One milligram of DNA was injected into each rabbit. Over a period of 2–6 months the mean serum cholesterol declined significantly below normal control levels. This change in the mean largely reflected the decline in cholesterol levels of those animals with high normal values. Concomitantly, the standard deviation and coefficient of variation of the serum cholesterol levels decreased to one-third the normal control values. The serum phospholipids and neutral fat showed similar lower mean levels and decreasing variation. Evidence is presented that the injected DNA is the active material producing these changes. Homologous and heterologous DNA were equally effective. An hypothesis is suggested relating the DNA-induced changes in the serum lipids to polygenic regulatory systems.
