Despite increased access to contraception over the last 60 years, unplanned pregnancies continue to contribute to economic disparities and overpopulation. Additionally, the burden of family planning falls primarily on women, as a reliable pharmaceutical male contraceptive has yet to be developed. The objective of this literature-based systematic review was to identify compounds for future study from natural sources with potential nonhormonal male contraceptive activity. After the exclusion of extracts and compounds with known hormonal mechanisms, 26 unique compounds were identified from natural species. The plant source, compound class, structure, target, mechanism of action, safety/toxicity profile, and in vitro, in vivo, and human studies for each compound were evaluated and discussed. β-Caryophyllene, embelin, oleanolic acid, triptonide, and N-butyldeoxynojirimycin (NB-DNJ) were selected as the five most promising compounds for future study using prespecified criteria such as number of studies, efficacy and safety profile, reversibility, and previous use in humans for any indication. In order to move forward with development of a male contraceptive from a natural source, additional studies are needed to determine the predicted safety and efficacy for in vivo and human clinical trials.

Chronically uncontrolled hyperglycemia is the leading cause of end stage kidney disease (ESKD) necessitating dialysis. During times of transition to hemodialysis (HD) or peritoneal dialysis (PD), considerations must be given to insulin dosing adjustments for persons with diabetes (PWD) in efforts to maintain glycemic control. However, the literature is sparse with few clear and direct practical clinical recommendations for therapeutic insulin dosing adjustments in PWD and ESKD. The objective of this systematic review was to identify and report the evidence and gaps in the literature for adjustments in therapeutic insulin recommendations when initiating HD or PD in patients with ESKD and diabetes mellitus. A literature search using PubMed, CENTRAL, MEDLINE, CINAHL, Google Scholar, and ClinicalTrials.gov revealed 242 results. After removing duplicates and articles not reaching pre-specified criteria, 29 relevant articles remained for further analysis. Following the exclusion of 18 articles after full-text review due to lack of relevance or inappropriate publication type, 11 articles remained and were included in the review. The most common recommendation regarding HD was to reduce the basal insulin dose up to 25% on HD days to prevent hypoglycemia, although a lack of consensus exists on the percent reduction. Little information was found relating to insulin management with continuous ambulatory PD or automated PD. During PD, insulin may be administered subcutaneously, IP, or with the dialysis fluid. Administration of insulin with dialysate may necessitate a dose increase of up to 30% due to a loss to tubing and dilution. Furthermore, the use of dextrose-based dialysate may require additional insulin to mitigate systemic impact of dextrose absorption on BG. Overall, a gap exists in the primary literature regarding recommendations for prophylactically adjusting insulin therapy when initiating HD or PD, or when switching between the two. More research is needed to clarify ideal alterations in insulin dosing, administration techniques, and product selections for PWD and ESKD undergoing dialysis.

A literature search using PubMed, CENTRAL, MEDLINE, CINAHL, Google Scholar, and ClinicalTrials.gov revealed 184 results. After removing duplicates and articles not reaching pre-specified criteria, 29 relevant articles remained for further analysis. The most common recommendation regarding HD was to reduce the basal insulin dose up to 25% on HD days to prevent hypoglycemia, although a lack of consensus exists on the percent reduction. Little information was found as to insulin management with continuous ambulatory PD (CAPD) or automated PD (APD). During PD, insulin may be administered subcutaneously, intraperitoneally, or with the dialysis fluid. Administration of insulin with dialysate may necessitate a dose increase of up to 30% due to a loss to tubing and dilution. Furthermore, the use of dextrose-based dialysate may require additional insulin to mitigate systemic impact of dextrose absorption on blood glucose. Overall, a gap exists in the primary literature regarding recommendations for prophylactically adjusting insulin therapy when initiating HD or PD, or when switching between the two. Greater research is needed to clarify ideal alterations in insulin dosing, administration techniques, and product selections for this patient population. Disclosure R. Tumlinson: None. E.
