IntroductionAltitude cannot be adjusted yet can still impact quality of play and concussion incidence. The current body of published evidence evaluating environmental effects on concussion is divided. We aim to systematically compare the prevalence of concussions that occur utilizing 1,000 feet as a marker for high altitude. Our research also takes a novel approach utilizing average games missed as a proxy for concussion severity.MethodsData on concussion incidence for the 2013–2017 National Hockey League seasons was collected utilizing FOX Sports, Hockey Reference and elevation map. We adopted 1,000 feet (304.8 meters) as high-low altitude cutoff. We also evaluated our data utilizing a previously published high-low altitude cutoff of 644 feet. One caveat to our data collection was the striking lack of publicly available data pertaining to the concussions sustained by each NHL team. Data was analyzed utilizing SAS programing.ResultsWe documented 133 concussions through the 2013–2017 NHL seasons. We noted an increase in concussion reporting during the most recent 2016–2017 season compared to previous ones. Effect of altitude variance on concussion rate was evaluated utilizing 644 and 1000 ft as the altitude split. This produced 4 distinct categories: (1) low-low, (2) low-high, (3) high-low, and (4) high-high. We noted a significant difference in concussion rate when teams based at altitude above 1,000 ft played at low altitude. Average games missed demonstrated that teams above 1,000 feet experienced less games missed compared to low altitude teams.ConclusionsThough underreported in the total number of concussions, our data suggests that high altitude teams experience a reduction in mean concussion rate when playing at lower altitudes. Our data also indicated a reduction in average games missed post-concussion for higher altitude teams. We hope our findings contribute to a larger discussion about concussion incidence and can be applied to additional sports leagues.

Introduction The incidence of gastric ulcers in patients with abdominal stoma is high and affects the quality of patients’ life. Aim To evaluate the effect of Adib herbal ointment containing chamomile rose, black nightshade origin versus Comfeel and Conveen ointments on the skin of abdominal stoma. Material and methods This is a clinical study in which the volunteers were stoma patients. Study group consisted of 52 qualified subjects, 26 were included in the experimental group and 26 in the control group. A 2-part questionnaire was used for the data collection. The 1st part was demographic information. The 2nd part of the data collection was evaluated according to the pressure ulcer scale for healing (PUSH) tool, which used for examining skin ulcers around the stoma. P ≤ 0.05 was considered as a significant. Results and discussion The results of the Mann–Whitney test showed that between the mean score of the total score of the wound before intervention (P = 0.92) and on the 3rd day (P = 0.476), 6th (P = 0.222), 9th (P = 0.11) and 12th (P = 0.418), there was no significant difference between the control and test groups. Also, the Friedman test (intra-group) also showed that between the mean score of the total score of the wound before the intervention and the 3rd, 6th, 9th and 12th days in the control group (P = 0.0001) and in the experimental group (P = 0.0001) There was a significant statistical difference. Conclusions Based on the study, Adib herbal ointment could be recommended for the treatment of stoma to the skin as an herbal product as other common treatments.

Abstract. Using TOMS total-ozone measurements over high-altitude cloud locations and nearby paired clear locations, we describe the Clear-Cloudy Pairs (CCP) method for deriving tropical tropospheric ozone. The high-altitude clouds are identified by measured 380 nm reflectivities greater than 80% and Temperature Humidity InfraRed (THIR) measured cloud-top pressures less than 200 hPa. To account for locations without high-altitude clouds, we apply a zonal sine fitting to the stratospheric ozone derived from available cloudy points, resulting in a wave-one amplitude of about 4 DU. THIR data is unavailable after November 1984, so we extend the CCP method by using a reflectivity threshold of 90% to identify high-altitude clouds and remove the influence of high-reflectivity-but-low-altitude clouds with a lowpass frequency filter. We correct ozone retrieval errors associated with clouds, and ozone retrieval errors due to sun glint and aerosols. Comparing CCP results with Southern Hemisphere ADditional OZonesondes (SHADOZ) tropospheric ozone indicates that CCP tropospheric ozone and ozonesonde measurements are highly consistent. The most significant difference between CCP and ozonesonde tropospheric ozone can be explained by the low Total Ozone Mapping Spectrometer (TOMS) retrieval efficiency of ozone in the lower troposphere.

This article describes a novel approach to reciprocal peer interviewing in which participants interview one another sequentially, allowing each the space of a full interview to articulate her experiences and reflections. This structure of data collection offers a new conceptualization of the way that elicitation functions; not just as a process inside of an interview, but one that is also shaped by factors preceding and outside of the individual interview, a process we call “meta-elicitation.” We argue that this form of reciprocal peer interviewing offers a view of the emic that is both participant-led and uniquely balanced between collective and individual perspectives. However, we also argue that shared authority and rapport are actively, and not always successfully, negotiated in such interviews. To prepare participants for peer interviewing, we hosted a 1-day workshop involving interview training, planning, and the recording of interviews. To maximize quality of such projects, we recommend that external researchers consider carefully (1) the balance of structure and flexibility in designing the workshop and interviews, (2) thorough preparation of participants, and (3) the role of meta-elicitation dynamics during analysis.

Comparing CCP results with Southern Hemisphere ADditional OZonesondes (SHADOZ) tropospheric ozone indicates that CCP tropospheric ozone and ozonesonde measurements agree, on average, to within 3 ± 1 DU standard error of the mean. The most significant difference between CCP and ozonesonde tropospheric ozone can be explained by the low Total Ozone Mapping Spectrometer (TOMS) version-7 retrieval efficiency of ozone in the lower troposphere.

AbstractHigh altitude hypoxia is believed to be experienced at elevations more than 2500 meters. A few studies have shed light on the biochemical aspects of high altitude acclimatization that profoundly included the subjects sojourning to the high altitude from low altitude and observation of the transient changes. However, information regarding the difference between the adapted people in high altitude and their counterpart, who reside in the low altitude are lacking. To address that issue, we have measured various hematological parameters and level of serum erythropoietin (EPO) in Tibetan population, who are residing in both high and low altitudes. We observed significant difference (p value < 0.0001) between high and low altitude Tibetan, in various hematological parameters, including red blood cells (RBC) count, hematocrit (HCT) or packed cell volume (PCV), and hemoglobin concentration (Hb). In case of mean corpuscular volume (MCV), significant difference was observed only in females (p value < 0.0001). Mean corpuscular hemoglobin concentration (MCHC) was significantly different between both males and females, but age was a potential confounder. There was no significant difference in serum EPO level between these two groups, either in males or females, which might be due to blunted erythropoietin response in the Tibetan population. We have also analyzed correlation between serum EPO with Hb and serum EPO with HCT and found no significant correlation. In multiple regression analysis, low altitude and male-gender showed significant impact on both Hb and HCT. In conclusion, our study suggests significant perturbation of hematological parameters, when native high altitude populations migrated to low altitude and inhabited for a long period.

Objective: The study is a descriptive and cross-sectional study designed to determine the quality of nursing care and the factors affecting quality of nursing care in a palliative care clinic.Material and method: The population and the sample of the study consisted of nurses (n=16) who were working in a palliative care clinic at a state hospital in the west of the Turkey and patients (n=102) who take care in this clinic between the date between January 2015 and October 2016. The sample size was not calculated and all the nurses and patients who met the study criteria and agreed to participate in the study were reached during the data collection period. Data collection was collected with a questionnaire consisted from Nurse Presentation Form, Patient Presentation Form and Care Behaviors-24 Scale (BDI-24). Student t, Kruskal-Wallis, Mann-Whitney U test and One Way ANOVA test were used in the analysis of the data.Results: The average score of BDI-24 was found as 5.59 ± 0.15 for nurses and 5.10 ± 0.15 for patients. There was no statistically significant difference between the average of BDI-24 total points and subscale scores of nurses according to their gender, education status, working duration in palliative care clinic and weekly working hours. Similarly, there was no statistically significant difference between the BDI-24 total point average and subscale scores of the patients according to the diagnosis, gender, marital status, educational status, occupation, income level and place of residence. Conclusion: The level of perception of nursing care behaviors of palliative care nurses and patients was found to be fairly high. It is proposed to identify and improve institutional deficiencies such as number of nurses, number of patients, workload, working hours, which affect the quality of nursing care.Extended English abstract is in the end of PDF (TURKISH) file. ÖzetAmaç: Araştırma, bir palyatif bakım kliniğinde hemşirelik bakım kalitesini ve bakım kalitesini faktörleri belirlemek amacıyla yapılmış tanımlayıcı ve kesitsel bir çalışmadır.Materyal ve Method: Araştırma Türkiye’nin batısında bir devlet hastanesinin palyatif bakım kliniğinde çalışan hemşireler (n=16) ile Ocak-Ekim 2015 tarihleri arasında palyatif bakım kliniğinde yatan hastalar (n=102) oluşturmuştur.

Exposure to chronic hypoxia during gestation predisposes infants to neonatal pulmonary hypertension, but the underlying mechanisms remain unclear. Here, we test the hypothesis that moderate continuous hypoxia during gestation causes changes in the rho-kinase pathway that persist in the newborn period, altering vessel tone and responsiveness. Lambs kept at 3,801 m above sea level during gestation and the first 2 wk of life were compared with those with gestation at low altitude. In vitro studies of isolated pulmonary arterial rings found a more forceful contraction in response to KCl and 5-HT in high-altitude compared with low-altitude lambs. There was no difference between the effects of blockers of various pathways of extracellular Ca2+ entry in low- and high-altitude arteries. In contrast, inhibition of rho-kinase resulted in significantly greater attenuation of 5-HT constriction in high-altitude compared with low-altitude arteries. High-altitude lambs had higher baseline pulmonary artery pressures and greater elevations in pulmonary artery pressure during 15 min of acute hypoxia compared with low-altitude lambs. Despite evidence for an increased role for rho-kinase in high-altitude arteries, in vivo studies found no significant difference between the effects of rho-kinase inhibition on hypoxic pulmonary vasoconstriction in intact high-altitude and low-altitude lambs. We conclude that chronic hypoxia in utero results in increased vasopressor response to both acute hypoxia and serotonin, but that rho-kinase is involved only in the increased response to serotonin.
