The Mill River Greenway Initiative: Community-Based, Long-Term Greenway Planning and Design In Williamsburg and Northampton, Massachusetts

Puritans first settled Northampton, Massachusetts in the mid-17th century with a vision in mind – that of a well-ordered community in which the Mill River would play an integral part in their lives. So long as the community hewed to the right path, the river would accommodate the community’s needs. Primary among those needs was waterpower, so the anchor sites for development along the river were the falls. Over the next 200 years, as the Puritan mind metamorphosed into an American industrial mentality, the Mill River’s residents created an industrial necklace with mills and factories decorating a ribbon of water. By the mid-19th century, more than 70 mills and factories were established along 15 miles of river from Northampton’s Lower Mills up to Devil’s Den near the headwaters of the river in Goshen. By the mid-20th century, with the Mill River Valley’s industrial base in rapid decline, the necklace deteriorated into a sad scattering of empty factory buildings with little connection to one another. The vision perished and the river escaped the minds of most residents, especially in Northampton where the Corps of Engineers relocated its flow away from the town center. Industry along the river is all but gone. Relic industrial sites now dot the Mill River’s banks, separated by flat stretches of the river that were never appealing for water-powered manufacturing. Though more prone to flooding, many of those stretches have been developed as recreational destinations. The Daughters of the American Revolution (D.A.R.) State Forest in Goshen and Look Park in Florence are just such places, but substantial inaccessible gaps remain between the old factory sites. The factories turned their backs to the river, severing any remaining connection to residents and visitors. There cannot be a true, continuous greenway if these key spots are not renewed and connected. The industrial sites themselves, called “anchor sites,” can serve as gateways and destination points along one continuous greenway, providing access to the stretches of river between them. A few anchor sites have been resuscitated or renovated, such as Meekins Library in Williamsburg Center and old mill buildings in Florence. People are returning, but the ways in which people and these sites relate to the river need to be addressed so that people can come back and reconnect to the river at historically and geographically significant locations. The Mill River Greenway Initiative is the story of a renewed vision, which, like the original, is being pieced together by individuals and small groups -- the creation of a new kind of necklace composed of those same sites at falls and bridges, which, when linked, will provide fulfillment for walkers, naturalists, and anglers, history buffs, artists, and tourists. The river will, once again, play an integral role in the lives of residents

Associations of reproductive factors with postmenopausal follicle stimulating hormone

Recent studies have suggested that higher postmenopausal follicle stimulating hormone (FSH) may be associated with lower risk of diabetes. However, relatively little is known about postmenopausal FSH levels, including the level of variation between women and whether reproductive factors are associated with this variation.Peer reviewe

Follicle-Stimulating Hormone is Associated with Lipids in Postmenopausal Women

Objective: The purpose of this study was to evaluate the relation between FSH and lipid levels in postmenopausal women from the Kuopio Ischaemic Heart Disease Risk Factor Study. Methods: Postmenopausal women (n = 588) aged 53 to 73 years and not using hormone therapy were included. The relation between FSH and total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TGs) was evaluated using linear regression, adjusting for estradiol, body mass, smoking, and other hormonal and lifestyle factors. The relation between FSH, dyslipidemia, and abnormal lipid levels were also evaluated. Results: FSH was positively and linearly associated with TC (P = 0.001) and LDL-C (P = 0.01) in all participants, with stronger relations seen in younger compared with older postmenopausal women. FSH was less strongly associated with HDL-C and TG. FSH was not associated with dyslipidemia; however, higher FSH was associated with increased risk of high TC (P = 0.02) and high LDL-C (P = 0.03). Conclusions: These data suggest that higher FSH in postmenopausal women is related to higher levels of both TC and LDL-C

Do Dietary Patterns Explain High Prevalence of Cardiovascular Risk Factors Among Pakistani Urban Adults? A Cross-Sectional Study

Background The prevalence of cardiovascular disease (CVD) in South Asia is higher than in any other developing countries. The diversity of diets in populations among developing countries may be one explanation for the differences in CVD. This study was carried out to explore the association between dietary patterns and the presence of cardiovascular risk factors among Pakistani low income urban adults. Methods Socio demographic, physical activity and dietary information was collected from 1546 Pakistani subjects aged ≥40 years from the Control of Hypertension and Risk Attenuation (COBRA) study. Anthropometric, clinical and biomarker measures were assessed. Cluster analysis was used to identify dietary patterns from a food frequency questionnaire (FFQ) and multinomial regression was employed to investigate the association between dietary clusters and cardiovascular risk factors, using one of the dietary clusters as a reference category. Results The most prevalent CVD risk factors among participants were elevated low density lipoprotein- cholesterol (LDL-C) (69.8 %) and systolic blood pressure (SBP) (68.2 %), followed by central obesity (57.1 %), low levels of high density lipoprotein-Cholesterol (HDL-C) (56.3 %), overall obesity (46.0 %), high total cholesterol (32.3 %), and elevated fasting blood sugar (FBS) (34.9 %). The cluster analysis generated 3 non-overlapping diet patterns. Cluster 1(Traditional Pakistani Diet), was dominated by fruits, vegetables, milk products and chicken, included participants with high mean body mass index (BMI), waist circumference (WC), HDL-C and low mean SBP. Cluster 2 (Moderate Diet) reflected a moderate intake of most food items and included participants with significantly higher mean SBP. Cluster 3 (Fatty Diet) was characterized by high intake of beef, whole milk, paratha and lentils and those following this cluster had a low mean HDL-C and high SBP. In analyses controlling for age, gender, tobacco use and physical activity, participants in the Traditional diet cluster were more likely to be overweight (OR 1.39, 95 % CI 1.08 to 1.78) and high central adiposity (1.33, 95 % CI 1.04 to 1.71) than participants in the Moderate diet cluster, though less likely to have elevated SBP (OR 0.67, 95 % CI 0.51 to 0.86). LDL-C levels were higher in both the traditional Pakistani diet and Fatty diet cluster compared to the Moderate diet cluster. Low HDL-C was also more prevalent among the Traditional Pakistani diet cluster. Conclusion Among Pakistani population discernable diet patterns can be derived using clusters analysis. CVD risk factors prevalence differed by cluster membership, though relations for specific CVD risk are not consistent across clusters

Dietary Patterns and their Association with Hypertension Among Pakistani Urban Adults

Hypertension is one of the most common chronic diseases affecting more than 25% of adults worldwide. In Pakistan, 33% of the adult population suffers from hypertension. Numerous epidemiological studies have demonstrated the critical role of dietary patterns in the causation, prevention and management of hypertension. There’s a dearth of evidence from South Asia in this regard. The present study aimed to identify the association between dietary patterns and hypertension among 4304 low income urban adults who participated in the Control of Blood Pressure and Risk Attenuation (COBRA) study in Karachi, Pakistan. Dietary information was collected by a 33- item food frequency questionnaire and 3 unique dietary patterns namely; fat and sweet, fruit and vegetable, and seafood and yogurt patterns were derived using principal component factor analyses. We used univariate and multivariable logistic regression to examine the association between dietary patterns and hypertension. Men were more likely to have hypertension, while increase in age, and body mass index were also associated with hypertension (p\u3c0.001). After adjusting for age, gender, education, marital status, body mass index, and tobacco use; the seafood and yogurt pattern was less likely (OR=0.78: 95% CI: 0.63, 0.98; p-value 0.03) to be associated with hypertension, whereas no significant associations were seen for other two dietary patterns. These findings suggest that certain dietary patterns may be associated with hypertension among Pakistani low income urban adults

Caffeinated Coffee, Decaffeinated Coffee and Endometrial Cancer Risk: A Prospective Cohort Study among US Postmenopausal Women

There is plausible biological evidence as well as epidemiologic evidence to suggest coffee consumption may lower endometrial cancer risk. We evaluated the associations between self-reported total coffee, caffeinated coffee and decaffeinated coffee, and endometrial cancer risk using the Women’s Health Initiative Observational Study Research Materials obtained from the National Heart, Lung, and Blood Institute Biological Specimen and Data Repository Coordinating Center. Our primary analyses included 45,696 women and 427 incident endometrial cancer cases, diagnosed over a total of 342,927 person-years of follow-up. We used Cox-proportional hazard models to evaluate coffee consumption and endometrial cancer risk. Overall, we did not find an association between coffee consumption and endometrial cancer risk. Compared to non-daily drinkers (none or <1 cup/day), the multivariable adjusted hazard ratios for women who drank ≥4 cups/day were 0.86 (95% confidence interval (CI) 0.63, 1.18) for total coffee, 0.89 (95% CI 0.63, 1.27) for caffeinated coffee, and 0.51 (95% CI 0.25, 1.03) for decaf coffee. In subgroup analyses by body mass index (BMI) there were no associations among normal-weight and overweight women for total coffee and caffeinated coffee. However among obese women, compared to the referent group (none or <1 cup/day), the hazard ratios for women who drank ≥2 cups/day were: 0.72 (95% CI 0.50, 1.04) for total coffee and 0.66 (95% CI 0.45, 0.97) for caffeinated coffee. Hazard ratios for women who drank ≥2 cups/day for decaffeinated coffee drinkers were 0.67 (0.43-1.06), 0.93 (0.55-1.58) and 0.80 (0.49-1.30) for normal, overweight and obese women, respectively. Our study suggests that caffeinated coffee consumption may be associated with lower endometrial cancer risk among obese postmenopausal women, but the association with decaffeinated coffee remains unclear

Associations of Daily Eating Episodes, and Eating Away-from-home with Blood Level of Total Cholesterol

The objective of this investigation is to describe the associations of number of eating episodes and proportion of meals eaten away from home with total serum cholesterol. Data from 499 participants, recruited from a health maintenance organization in central Massachusetts, aged 20-70, were used for this analysis. Dietary information and total blood cholesterol were obtained at five sampling points (baseline and four consecutive quarters) during the one-year follow-up. A cross-sectional study was conducted. The results from the study do not support the hypothesis that the number of eating episodes per day is associated with total blood cholesterol. However, we noted that the mean concentration of total cholesterol decreased with increasing number of eating episodes among women, although the adjusted mean among three categories of number of eating episodes per day was not statistically significant. On the other hand, the results of our study suggest that increased frequency of meals (breakfast, lunch, or dinner) eaten away from home is positively associated with mean total blood cholesterol concentration. Furthermore, meals eaten away from home, especially breakfast and dinner, were significantly higher in total calories, and percent calories from total and saturated fat, but lower in percent calories from protein and carbohydrate, and grams of fiber, than corresponding meals eaten at home. We conclude that eating out may have adverse influences on blood lipids. Further research is needed to better understand the impact of eating away from home on blood lipids

Plasma 25-hydroxyvitamin D and risk of premenstrual syndrome in a prospective cohort study

Background: Moderate to severe premenstrual syndrome (PMS) affects 8–20 percent of premenopausal women. Previous studies suggest that high dietary vitamin D intake may reduce risk. However, vitamin D status is influenced by both dietary vitamin D intake and sunlight exposure and the association of vitamin D status with PMS remains unclear. Methods: We assessed the relation of plasma 25-hydroxyvitamin D (25OHD), total calcium and parathyroid hormone levels with risk of PMS and specific menstrual symptoms in a case–control study nested within the prospective Nurses’ Health Study II. Cases were 401 women free from PMS at baseline who developed PMS during follow-up (1991–2005). Controls were women not experiencing PMS (1991–2005), matched 1:1 with cases on age and other factors. Timed luteal phase blood samples were collected between 1996 and 1999 from cases and controls. We used conditional logistic regression to model the relation of 25OHD levels with risk of PMS and individual menstrual symptoms. Results: In analyses of all cases and controls, 25OHD levels were not associated with risk of PMS. However, results differed when the timing of blood collection vs. PMS diagnosis was considered. Among cases who had already been diagnosed with PMS at the time of blood collection (n = 279), 25OHD levels were positively associated with PMS, with each 10 nmol/L change in 25OHD associated with a 13% higher risk. Among cases who developed PMS after blood collection (n = 123), 25OHD levels were unrelated to risk of PMS overall, but inversely related to risk of specific menstrual symptoms. For example, each 10 nmol/L increase was associated with a significant 21% lower risk of breast tenderness (P = 0.02). Total calcium or parathyroid hormone levels were unrelated to PMS. Conclusions: 25OHD levels were not associated with overall risk of PMS. The positive association observed among women already experiencing PMS at the time of 25OHD measurement is likely due to confounding by indication related to use of dietary supplements to treat menstrual symptoms. Results from prospective analyses, which were less likely influenced by this bias, suggest that higher 25OHD levels may be inversely related to the development of specific menstrual symptoms

A Spitzer IRS Study of Debris Disks Around Planet-Host Stars

Since giant planets scatter planetesimals within a few tidal radii of their orbits, the locations of existing planetesimal belts indicate regions where giant planet formation failed in bygone protostellar disks. Infrared observations of circumstellar dust produced by colliding planetesimals are therefore powerful probes of the formation histories of known planets. Here we present new Spitzer IRS spectrophotometry of 111 Solar-type stars, including 105 planet hosts. Our observations reveal 11 debris disks, including two previously undetected debris disks orbiting HD 108874 and HD 130322. Combining our 32 micron spectrophotometry with previously published MIPS photometry, we find that the majority of debris disks around planet hosts have temperatures in the range 60 < T < 100 K. Assuming a dust temperature T = 70 K, which is representative of the nine debris disks detected by both IRS and MIPS, we find that debris rings surrounding Sunlike stars orbit between 15 and 240 AU, depending on the mean particle size. Our observations imply that the planets detected by radial-velocity searches formed within 240 AU of their parent stars. If any of the debris disks studied here have mostly large, blackbody emitting grains, their companion giant planets must have formed in a narrow region between the ice line and 15 AU.Comment: Accepted for publication in the Astronomical Journal. 14 pages, including five figures and two table
