- This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete release of the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, which reached its goal of surveying over 10,000 nearby galaxies. The complete release of the MaNGA Stellar Library accompanies this data, providing observations of almost 30,000 stars through the MaNGA instrument during bright time. DR17 also contains the complete release of the Apache Point Observatory Galactic Evolution Experiment 2 survey that publicly releases infrared spectra of over 650,000 stars. The main sample from the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), as well as the subsurvey Time Domain Spectroscopic Survey data were fully released in DR16. New single-fiber optical spectroscopy released in DR17 is from the SPectroscipic IDentification of ERosita Survey subsurvey and the eBOSS-RM program. Along with the primary data sets, DR17 includes 25 new or updated value-added catalogs. This paper concludes the release of SDSS-IV survey data. SDSS continues into its fifth phase with observations already underway for the Milky Way Mapper, Local Volume Mapper, and Black Hole Mapper surveys.

- BACKGROUND: Dynamic cerebral autoregulation and cerebral perfusion pressure are altered in pregnancies complicated by preeclampsia compared with normotensive pregnancies, but the connections of dynamic cerebral autoregulation, cerebral perfusion pressure, and cerebral complications in preeclampsia remain unclear. OBJECTIVE: This study aimed to assess dynamic cerebral autoregulation and cerebral perfusion pressure after delivery in women with eclampsia, in women with preeclampsia both with and without severe features, and in normotensive women. STUDY DESIGN: This was a prospective case control study at a large referral hospital in Cape Town, South Africa. The recruitment of participants was done at diagnosis (cases) or at admission for delivery (controls). Transcranial Doppler examinations with continuous noninvasive blood pressure measurements and end-tidal CO2 monitoring were conducted for cases and controls after delivery. Cerebral perfusion pressure and dynamic cerebral autoregulation index were calculated, and values were compared among groups. RESULTS: We included 16 women with eclampsia, 18 women with preeclampsia with severe features, 32 women with preeclampsia without severe features, and 21 normotensive women with uncomplicated pregnancies. Dynamic cerebral autoregulation was depressed in pregnant women with eclampsia; (autoregulation index, 3.9; interquartile range, 3.1-5.2) compared with all other groups (those with preeclampsia with severe features, autoregulation index, 5.6 [interquartile range, 4.4-6.8]; those with preeclampsia without severe features, autoregulation index, 6.8 [interquartile range, 5.1-7.4]; and normotensive controls, autoregulation index, 7.1 [interquartile range, 6.1-7.9]). Pregnant women with eclampsia had increased cerebral perfusion pressure (109.5 mm Hg; interquartile range, 91.2-130.9) compared with those with preeclampsia without severe features and those with normal blood pressure (84 mm Hg [interquartile range, 73.0-122.0] and 80.0 mm Hg [interquartile range, 67.5-92.0], respectively); furthermore, there was no difference in cerebral perfusion pressure between pregnant women with eclampsia and pregnant women with preeclampsia with severe features (109.5 mm Hg [interquartile range, 91.2-130.9] vs 96.5 mm Hg [interquartile range, 75.8-110.5]). CONCLUSION: Cerebral perfusion pressure and dynamic cerebral autoregulation are altered in eclampsia and may be important in the pathophysiological pathway and constitute a therapeutic target in the prevention of cerebral complications in preeclampsia.

- The association between pesticide exposure and non-Hodgkin lymphoma (NHL) including hairy cell leukemia (HCL) was analyzed in a pooled study of three case-control studies. Results on exposure to pesticides were based on 1,425 cases and 2,157 controls participating in the studies. Exposures were assessed by self-administered questionnaires completed as needed by phone. In the pooled univariate analyses adjusted by age, gender and year of diagnosis, exposure to herbicides of the phenoxyacetic acid type yielded statistically significant increased risk with odds ratio (OR) = 1.9, 95% confidence interval CI) = 1.4–2.5. The herbicide glyphosate gave OR = 2.2, 95% CI = 1.3–3.8. Impregnating agents increased the risk. No clear dose-response effect was seen. OR was highest in the >10–20 years latency group for herbicides and impregnating agents. In the multivariate analysis including main pesticide groups, statistically significant increased risk was found for herbicides, OR = 1.6, 95% CI = 1.2–2.1 and impregnating agents with OR = 1.4, 95% CI = 1.1–1.8. This analysis confirmed an association between NHL including HCL and exposure to certain herbicides.

- Objective: This study examined the recent national and regional incidence of lower limb amputations (LLAs) in Sweden and their annual changes.Methods: This was an observational study using Swedish national register data. All initial amputations were identified in Sweden from 2008 to 2017 in individuals 18 years or older using the national inpatient register. The amputations were categorised into three levels: high proximal (through or above the knee joint), low proximal (through the tibia to through the ankle joint), and partial foot amputations. To examine the national and regional incidence and annual changes, the age, sex, and region specific population count each year was used as the denominator and Poisson regression or negative binomial regression models were used to estimate incidence rate ratios (IRRs) and 95% confidence intervals (CIs) adjusted for age and sex.Results: The national annual incidence of LLAs was 22.1 per 100 000 inhabitants, with a higher incidence in men (24.2) than in women (20.0). The incidence of LLAs (all levels combined) declined during the study period, with an IRR of 0.984 per year (95% CI 0.973 - 0.994). This was mainly due to a decrease in high proximal amputations (0.985, 95% CI 0.974 - 0.995) and low proximal amputations (0.973, 95% CI 0.962 - 0.984). No change in the incidence of partial foot amputations was observed (0.994, 95% CI 0.974 - 1.014). Such declines in LLA incidence (all levels combined) were observed in nine of the 21 regions. Compared with the national average and with adjustment for age, sex, diabetes, and artery disease, the regional IRR varied from 0.85 to 1.36 for all LLAs, from 0.67 to 1.61 for high proximal amputations, from 0.50 to 1.51 for low proximal amputations, and from 0.13 to 3.68 for partial foot amputations.Conclusion: The incidence of LLAs has decreased in Sweden. However, regional variations in incidence, time trends, and amputation levels warrant further research.

- Background: Atopic dermatitis is a chronic inflammatory skin disease and inflammation has been implicated in development of other chronic diseases, but few studies have examined the relationship with dementia.Objectives: This study examines associations of atopic dermatitis (AD) and systemic inflammation in adolescence measured using erythrocyte sedimenta-tion rate (ESR), as well as AD diagnosed in adulthood, with dementia risk.Methods: We used three Swedish register‐based cohorts. Cohort I (N= 795,680) comprised men, born in 1951–1968, who participated in themilitary conscription examinations with physician‐assessed AD and ESR; Cohort II (N= 1,757,600) included men and women, born in 1951–1968; and Cohort III (N= 3,988,783) included all individuals in Sweden, born in 1930–1968. We used Cox regression, estimating hazard ratios (HR), with thefollow‐up from 50 years of age to dementia diagnosis, date of emigration, death, or 31 December 2018, which ever occurred first. Further, we used asibling comparison design to adjust for unmeasured confounders shared among siblings.Results: Cohort I: 1466 dementia events were accrued during follow‐up of 7.8 years, with a crude rate of 21.6 [95% confidence interval (CI): 20.6, 22.8] per 100,000 person‐years. Cohort II: 3549 dementia events were accrued duringfollow‐up of 7.4 years, with a crude rate of 23.7 (95% CI: 22.9, 24.5) per 100,000 person‐years. Cohort III: 120,303 dementia events were accrued during follow‐up of 23.7 years, with a crude rate of 180.3 (95% CI: 179.3, 181.3) per 100,000 person‐years. In multivariable analysis using Cohort I, there was no association between AD and dementia [HR 0.68 (95% CI 0.32, 1.43)], norwith moderate [HR 0.71 (95% CI: 0.46, 1.10)] or high [HR 1.23 (95% CI: 0.87, 1.75)] ESR. AD was not associated with dementia risk in Cohort II [HR 1.28(0.97, 1.71)] or Cohort III [HR 1.01 (0.92, 1.11)].Conclusions: AD was not associated with dementia risk, neither was systemic inflammation measured by ESR in adolescence.
