India's high prevalence of iron-deficiency anemia has largely been attributed to the local diet consisting of nonheme iron, which has lower absorption than that of heme iron. We assessed the efficacy of the consumption of iron-supplement bars in raising hemoglobin concentrations and hematocrit percentages in anemic (hemoglobin concentration <12 g/dL) Indian women of reproductive age. The Let's be Well Red study was a 90-d, pair-matched, cluster-randomized controlled trial. A total of 361 nonpregnant women (age 18-35 y) were recruited from 10 sites within Mumbai and Navi Mumbai, India. All participants received anemia education and a complete blood count (CBC). Random assignment of anemic participants to intervention and control arms occurred within 5 matched site-pairs. Intervention participants received 1 iron-supplement bar (containing 14 mg Fe)/d for 90 d, whereas control subjects received nothing. CBC tests were given at days 15, 45, and 90. Primary outcomes were 90-d changes from baseline in hemoglobin concentrations and hematocrit percentages. Linear mixed models and generalized estimating equations were used to model continuous and binary outcomes, respectively. Of 179 anemic participants, 136 (76.0%) completed all follow-up assessments (65 intervention and 71 control participants). Baseline characteristics were comparable by arm. Mean hemoglobin and hematocrit increases after 90 d were greater for intervention than for control participants [1.4 g/dL (95% CI: 1.3, 1.6 g/dL) and 2.7% (95% CI: 2.2%, 3.2%), respectively]. The anemia prevalence at 90 d was lower for intervention (29.2%) than for control participants (98.6%) (OR: 0.007; 95% CI: 0.001, 0.04). The daily consumption of an iron-supplement bar leads to increased hemoglobin concentrations and hematocrit percentages and to a lower anemia prevalence in the target population with no reported side effects. This intervention is an attractive option to combat anemia in India. This trial was registered at clinicaltrials.gov as NCT02032615.

The role of metformin in prostate cancer chemoprevention remains unclear. REDUCE, which followed biopsy-negative men with protocol-dictated PSA-independent biopsies at 2- and 4-years, provides an opportunity to evaluate the link between metformin use and prostate cancer diagnosis with minimal confounding from screening biases. In diabetic men from REDUCE, we tested the association between metformin use, use of other anti-diabetic medications, vs. no anti-diabetic medication use and prostate cancer diagnosis as well as prostate cancer grade (low-grade Gleason 4–6, high-grade Gleason 7–10) using logistic regression. Of the 540 diabetic men with complete data, 205 (38%) did not report use of any anti-diabetic medications, 141 (26%) reported use of at least one anti-diabetic medication other than metformin, and 194 (36%) reported use of metformin. During the 4-year study, 122 men (23%) were diagnosed with prostate cancer. After adjusting for various clinical and demographic characteristics, we found that metformin use was not significantly associated with total (OR=1.19, p=0.50), low- (OR=1.01, p=0.96), or high-grade (OR=1.83, p=0.19) prostate cancer diagnosis. Likewise, there was no significant association between the use of non-metformin anti-diabetic medications and prostate cancer risk in both crude (OR=1.02, p=0.95) and multivariable analysis (OR=0.85, p=0.56). Furthermore, the interactions between anti-diabetic medication use and BMI, geographic location, coronary artery disease, smoking, and treatment group were not significant (all p>0.05). Among diabetic men with a negative pre-study biopsy who all underwent biopsies largely independent of PSA, metformin use was not associated with reduced risk of prostate cancer diagnosis.

Among men with prostate-specific antigen ≤10 ng/mL and clinical stage T1c/T2a, those in grade group 2 with ≤2 total positive cores have similar rates of adverse pathology and biochemical recurrence as men with grade group 1.

6 Background: Study compliance is crucial when the study outcome is determined by an invasive procedure, such as prostate biopsy. To investigate predictors of compliance in study-mandated prostate biopsies, we analyzed demographic, clinical and reported lifestyle data from the REDUCE trial. Methods: We retrospectively identified 8,062 men from REDUCE with at least 2-years of follow-up, and used multivariable logistic regression to test the association between baseline demographic and clinical characteristics and undergoing the study-mandated prostate biopsy at 2 years. We then examined whether missing any of these data was associated with undergoing a biopsy. Results: In REDUCE, 20% of men did not undergo a 2-year biopsy.On multivariable analysis, non-North American region was predictive of 35-55% increased likelihood of undergoing a 2-year biopsy (p ≤ 0.001). Being enrolled at a center that enrolled >10 subjects (2nd and 3rd tertile) was associated with a 40-49% increased likelihood of undergoing a 2-year biopsy (p < 0.001). Missing one or more baseline variables was associated with a 25% decreased likelihood of undergoing a 2-year biopsy (OR = 0.75; p = 0.002). Conclusions: In REDUCE, men outside North America, those at higher volume centers, and those with complete baseline data were more likely to undergo study mandated 2-year biopsies. Given prostate biopsy is becoming increasingly utilized as an endpoint in trials that are often multi-national, regional differences in compliance should be considered when designing future trials. Likewise, efforts are needed to ensure compliance in low-volume centers or among subjects missing baseline data.

Objective: To evaluate performance of pelvic lymph node dissection during radical prostatectomy within an equal access care setting over a period of time, and stratified by prostate cancer risk group and surgical technique. Methods: We identified men in the Shared Equal Access Regional Cancer Hospital database who had open or robotic-assisted radical prostatectomy from 2006 to 2013. Univariable logistic regression was used to test the association between age, race, body mass index, total biopsy cores, number of positive biopsy cores, risk group, year, center, surgical volume and surgical technique on pelvic lymph node dissection use. Multivariable logistic analysis was used to examine surgical technique and pelvic lymph node dissection performance. Spearman's correlation examined temporal changes in pelvic lymph node dissection utilization stratified by risk group and surgical technique. Results: A total of 1425 men met inclusion criteria; 67% of them underwent pelvic lymph node dissection. On multivariable analysis, robotic-assisted radical prostatectomy was associated with an 92% decreased use of pelvic lymph node dissection in low-risk, 84% decreased in intermediate-risk and 91% decreased in high-risk men (all P < 0.001). In robotic-assisted radical prostatectomy, there was a trend for increased pelvic lymph node dissection utilization over time in high-risk men (Spearman; P = 0.077) reaching 85% in 2012-2013, which was accompanied by increased use in low-risk men (P = 0.016). For open radical prostatectomy, fewer pelvic lymph node dissections were carried out in low-risk men over time, decreasing to~35% (P = 0.047) in 2012-2013, whereas rates remained high for high-risk men throughout (~95%; P = 0.621). Conclusion: Regardless of risk group, pelvic lymph node dissection is carried out significantly less during robotic-assisted radical prostatectomy. For robotic-assisted radical prostatectomy, pelvic lymph node dissection utilization increased over time for high-risk men, but rates also increased for low-risk men. Further attention to the discrepancy between provided and guideline recommended pelvic lymph node dissection performance is required to improve prostate cancer care.

had greater core positivity, and a higher incidence of clinically significant disease. These results suggest that high risk patients in an inner city setting are also being negatively affected by the implementation of the task force recommendations. Further research is required to determine whether the practice pattern change occurred at the level of PSA screening or rather at patient selection for prostate biopsy. Such research will allow clinicians to provide more granular counseling with regards to PSA screening and prostate biopsies for high risk patients.

metastases undergoing lymphadenectomy in this cohort of HLRCC patients progressed to develop metastatic disease. Loco-regional lymphadenectomy appears to have an important role in the treatment of patients with HLRCC and renal tumors.
