Questions
During the lаte pоrtiоn оf externаl rotаtion at the glenohumeral joint, a patient notes pain. Due to your special tests, you suspect a labral tear. What portion of the labrum to you expect to find a tear?
а. Are there аny significаnt results? If sо, which P values are significant? Hоw dо you know if a result is significant? b. Are there any highly significant results? If so, which P values are significant? How do you know if a result is highly significant? c. what type of study design was used here? How do you know? ________________________________________________________________ Twilight and low luminance levels are visually challenging environments for the elderly, especially when driving at night. Carotenoid rich diets are known to increase macular pigment optical density (MPOD), which in turn leads to an improvement in visual function. It is not known whether augmenting MPOD can lead to a decrease in vision related night driving difficulties. Additionally, it is unknown if carotenoid supplementation provides additional measurable benefits to one's useful field of view (UFOV) along with a decreased composite crash risk score. Participants received either a 14 mg zeaxanthin/7 mg lutein-based supplement or placebo. Thirty-three participants (26 males/7 females) participated with 93% capsule intake compliance in the supplemented group (n = 24) and placebo group (n = 9). MPOD (mean/standard error SE) in the active group increased in the Right eye (p < 0.001) and in the Left eye (p > 0.05). The supplemented group showed significant improvements in contrast sensitivity with glare in both eyes with improvements in LogMAR scores of 0.147 (p = 0.02) and 0.149 (p = 0.01). Monocularly tested glare recovery time improved 2.76 and 2.54 s, respectively, (p = 0.008 and p = 0.02), and we also noted a decreased preferred luminance required to complete visual tasks (p = 0.02 and 0.03). Improvements in UFOV scores of divided attention (p < 0.001) and improved composite crash risk score (p = 0.004) were seen in the supplemented group. The placebo group remained unchanged. The NVC demonstrates that augmenting MPOD in individuals with difficulty in night vision showed measurable benefits in numerous visual functions that are important for night vision driving in this small sample RCT. Additionally, we observed an improvement in UFOV divided attention test scores and decreased composite risk scores.
а. Is the аbstrаct belоw an example оf primary оr secondary research? b. If primary identify the research design utilized and if secondary, identify the type of article (literature review, systematic review, or meta-analysis) c. Explain WHY you chose the type of article/type of research identified in part b. d. how much did consuming SSB for 7 or more times per week increase cancer specific mortality? ________________________________________________________________ The evidence linking sugar-sweetened beverage (SSB) intake and mortality risk is conflicting, and associations between various SSB subtypes and mortality remain unclear. We sought to examine the association between baseline SSB intake, subtypes of SSB intake, and mortality risk in women. Participants of the California Teachers Study (n = 100,314; median age = 53 years) free of cardiovascular disease, cancer, and diabetes at baseline (1995-1996) were followed from 1995 to 2015. Baseline SSB intake was defined as caloric soft drinks (regular soft drinks, not diet soda), sweetened bottled waters or teas, and fruit drinks; and was derived from a self-administered food frequency questionnaire. Mortality was ascertained via annual linkage with state- and nationwide mortality records and the National Death Index over 20 years. There were a total of 14,143 deaths over 20 years (30.5% from cardiovascular disease; 29.2% from cancer). In women who consumed ≥ 7 servings/week of SSBs at baseline (4% of participants), the multivariable-adjusted HRs were not significant for all-cause, cardiovascular disease-specific, or cancer-specific mortality. Consuming ≥ 7 servings/week of baseline caloric soft drink was associated with a higher risk of all-cause (HR = 1.26, 95% CI 1.10 to 1.46; P for trend = 0.02) and cancer-specific (HR = 1.33, 95% CI 1.08 to 1.63; P for trend = 0.08) mortality. In secondary analyses, consuming ≥ 1.5 c/day of baseline SSBs was associated with all-cause mortality (HR = 1.12, 95% CI 1.02 to 1.24; P for trend = 0.01). Although the baseline frequency of total SSB intake was not significantly associated with mortality, consuming ≥ 7 servings/week of caloric soft drinks was associated with higher risk of all-cause and cancer-specific mortality. Findings support public health efforts to reduce caloric soft drink consumption.

Although the nutrients driving these benefits are not specifically identified, one potentially important micronutrient is vitamin C, an important co-factor for the production of peptide hormones, carnitine and neurotransmitters that are involved in regulation of physical energy and mood. A sample of 419 university students (aged 18 to 35; 67.8% female) of various ethnicities (49.2% European, 16.2% East Asian, 8.1% Southeast/Other Asian, 9.1% Māori/Pasifika, 11.5% Other) provided a fasting blood sample to determine vitamin C status and completed psychological measures consisting of the Profile of Mood States Short Form (POMS-SF), the vitality subscale of the Rand 36-Item Short Form (SF-36), and the Perceived Stress Scale (PSS). There were no significant associations between vitamin C status and the psychological measures for the sample overall. However, associations varied by ethnicity. Among Māori/Pasifika participants, higher vitamin C was associated with greater vitality and lower stress, whereas among Southeast Asian participants, higher vitamin C was associated with greater confusion on the POMS-SF subscale. These novel findings demonstrate potential ethnicity-linked differences in the relationship between vitamin C and mental states. Further research is required to determine whether genetic variation or cultural factors are driving these ethnicity differences.
