Skylab short-lived event alert program

During the three manned Skylab missions, the Center for Short-Lived Phenomena (CSLP) reported a total of 39 significant events to the Johnson Space Center (JSC) as part of the Skylab Short-Lived Event Alert Program. The telegraphed daily status reports included the names and locations of the events, the track number and revolution number during which the event could be observed, the time (GMT) to within plus or minus 2 sec when Skylab was closest to the event area, and the light condition (daylight or darkness) at that time and place. The messages sent to JSC during the Skylab 4 mission also included information pertaining to ground-truth studies and observations being conducted on the events. Photographic priorities were assigned for each event

Prevalence of hamstrings tightness and its impact on lower extremity function in asymptomatic individuals with prolonged standing hours

Background: Hamstrings undergo adaptive shortening. It is common in healthy individuals to have a sedentary lifestyle affecting males (91.8%) more than females (78.7%). Hamstring tightness can interrupt ADL’s predisposing the person to further health problems i.e. plantar fasciitis, sacroiliac joint pain, decreased lumbar lordosis, knee pain, quadriceps malfunction, postural disturbances, overstretched lumbar ligaments, reduced muscle strength. Aims and Objectives: To analyze the prevalence of hamstring tightness and its effects on lower extremity function in individuals with prolonged standing. Materials and Methods: 65 participants were chosen for this cross-sectional study by convenient sampling; all were female nurses. The hamstring tightness was measured by the data collection tools i.e. lower limb task questionnaire, straight leg raise test, and active knee extension test after having the consent forms signed by the participants. The data was collected from three big hospitals in the city. Results: The results of the study conducted to see the prevalence of hamstrings tightness and its impact on lower extremity function in asymptomatic individuals with prolonged standing hours showed that only 15.38% of the sample (n=65) with a mean age of 31-35 years were found with bilateral hamstrings tightness while 84.62% were found with no hamstrings tightness. Conclusion: The prevalence of hamstring tightness in asymptomatic individuals with prolonged standing hours is low

Effects of Nebivolol on Endothelial Function and Exercise Parameters in Patients with Slow Coronary Flow

Objective Earlier studies have reported that a decrease in exercise capacity might indicate endothelial dysfunction. However, the effects of improvement of endothelial functions on exercise capacity have not been evaluated. The aim of the present study is to investigate the effects of nebivolol on flow-mediated dilatation (FMD), and on the exercise capacities of the patients with slow coronary flow (SCF). Methods The study population included 25 subjects with SCF (Group 1) documented by the thrombolysis in myocardial infarction (TIMI) frame count, and 25 control group (Group 2) subjects with normal coronary angiography, for a total of 50 subjects who underwent coronary angiography due to several indications and had no coronary lesion. The TIMI frame count (TFC) values of the subjects in Group I for left anterior descending artery, right coronary, and circumflex coronary artery were 61.8 ± 30.6, 37.2 ± 17.4, and 34.6 ± 17.4, respectively. All the subjects received nebivolol 5 mg/day. Results At the end of the first month of FMD, the mean exercise duration (MED) and the Duke Scores of the patients with SCF were significantly higher than the baseline values. However, the values by the sixth month did not differ from that at the first month. Although a numerical improvement compared to the baseline values was observed for the subjects in Group 2 by the measurements at the end of the first and the sixth month, this difference was not statistically significant. Conclusions Nebivolol treatment increases FMD in the subjects with SCF. The difference in the exercise parameters of these subjects is particularly dramatic, and such an outcome may indirectly indicate long-term improvement in endothelial function

ESTIMATED DAILY INTAKE AND EXPOSURE OF SODIUM BENZOATE AND POTASSIUM SORBATE THROUGH FOOD PRODUCTS IN SCHOOL CHILDREN OF TIRUPATI, INDIA

Objective: According to Food Safety and Standards Authority of India (FSSAI) the preservatives, sodium benzoate and potassium sorbate belong to permitted class II preservatives. The aim of this study is to determine the concentration levels of these preservatives in food products that are consumed by school children and to assess the chronic dietary exposure by conducting the Total Diet Study (TDS).Methods: The quantitative determination was carried out by UV spectrophotometer. The absorbance for sodium benzoate and potassium sorbate were measured at 228 and 250 nm respectively. The 24-hour diet recall method was used to estimate the amount of food ate in last 24 hours. For estimation of preservative exposure dietary modelling techniques were utilized which combine the amount of preservative concentration present in that food with the amount of food consumed. Then the dietary exposure was assessed by considering the Acceptable Daily Intake (ADI).Results: The results include chemical concentration levels of the foods analyzed as well as estimated dietary exposures and contributions to the exposure from different foods. The obtained mean concentration of sodium benzoate was found to be425 ppm for sauces, 161 ppm for pickles and 80 ppm for soft drinks. Potassium sorbate was found to be 130 ppm for fruit juices,302 ppm for jellies and 380 ppm for jams. The highest mean dietary exposure for both the preservatives was observed in children of 2-7 years age group, the percentage exposure of sodium benzoate was 33% of the ADI and potassium sorbate was 17 % of the ADI.Conclusion: This study can enlighten the public on the consumption of preservative containing food products within the limit and encourages to eating fresh preservative free foods.Â

Adherence to oral glucose-lowering therapies and associations with 1-year HbA_1c:A retrospective cohort analysis in a large primary care database

JOURNAL ARTICLEOBJECTIVE: The impact of taking oral glucose-lowering medicines intermittently, rather than as recommended, is unclear. We conducted a retrospective cohort study using community-acquired U.K. clinical data (Clinical Practice Research Database [CPRD] and GoDARTS database) to examine the prevalence of nonadherence to treatment for type 2 diabetes and investigate its potential impact on HbA1c reduction stratified by type of glucose-lowering medication. RESEARCH DESIGN AND METHODS: Data were extracted for patients treated between 2004 and 2014 who were newly-prescribed metformin, sulfonylurea, thiazolidinedione, or dipeptidyl peptidase-4 inhibitors and who continued to obtain prescriptions over 1 year. Cohorts were defined by prescribed medication type, and good adherence was defined as a medication possession ratio ≥0.8. Linear regression was used to determine potential associations between adherence and 1-year baseline-adjusted HbA1c reduction. RESULTS: In CPRD and GoDARTS, 13% and 15% of patients, respectively, were nonadherent. Proportions of nonadherent patients varied by the oral glucose-lowering treatment prescribed (range 8.6% [thiazolidinedione] to 18.8% [metformin]). Nonadherent, compared with adherent, patients had a smaller HbA1c reduction (0.4% [4.4mmmol/mol] and 0.46% [5.0 mmol/mol] for CPRD and GoDARTs, respectively). Difference in HbA1c response for adherent compared with nonadherent patients varied by drug (range 0.38% [4.1 mmol/mol] to 0.75% [8.2 mmol/mol] lower in adherent group). Decreasing levels of adherence were consistently associated with a smaller reduction in HbA1c. CONCLUSIONS: Reduced medication adherence for commonly used glucose-lowering therapies among patients persisting with treatment is associated with smaller HbA1c reductions compared with those taking treatment as recommended. Differences observed in HbA1c responses to glucose-lowering treatments may be explained in part by their intermittent use.A.J.F. and R.R.H. are National Institute for Health Research (NIHR) Senior Investigators and receive additional support from the Oxford NIHR Biomedical Research Centre.

Clinical outcome of tapered wedge stem

The purpose of this study is to evaluate the results and intraoperative or postoperative complications of primary total hip arthroplasty (THA) using a contemporary tapered wedge titanium femoral component. A total of 213 THAs in 187 patients were followed up more than 5 years (mean, 102 months ; range, 60-150). The mean age at surgery was 64.2 years (range, 20–89 years). These patients were clinically evaluated using the JOA scoring system and radiographically host bone reactions around the implants, as well as femoral loosening. The mean JOA score improved from 49 (range, 21–75) to 92 (range, 59–100). All 12 patients with poor results (JOA < 75) coexisted with cerebral, spinal, joint, and musculoskeletal disorders. At the final follow-up, implant survival was 100%. Complications occurred in 23 hips. They consisted of 12 hips with intra-operative fractures, 2 hips with sciatic nerve palsy, one hip with infections, 3 hips with recurrent dislocations, and 8 hips with aseptic cup loosening. In conclusion, we have shown excellent survival rate of the contemporary tapered wedge stem in primary THA ; however, patients with coexisting diseases could not acquire sufficient improvement in hip function and ambulatory ability
