Objective: To assess the evolving standards of care for hyperparathyroidism in kidney transplant candidates. Methods: An 11-question, Institutional Review Board-approved survey was designed and reviewed by multiple institutions. The questionnaire was made available to the American Society of Transplantation's Kidney Pancreas Community of Practice membership via their online hub from April through July 2019. Results: Twenty percent (n = 41) of kidney transplant centers responded out of 202 programs in the United States. Forty-one percent (n = 17) of respondents believed medical literature supports the concept that a serum parathyroid hormone level greater than 800 pg/mL could endanger the survival of a transplanted kidney and therefore makes transplantation in an affected patient relatively or absolutely contraindicated. ⋯ The majority of respondents (71%, n = 29) do not involve endocrinologists in the management of kidney transplantation candidates. Conclusion: Our survey shows wide divergence of clinical practice in the area of surgical management of kidney transplantation candidates with hyperparathyroidism. We suggest that medical/surgical societies involved in the transplantation care spectrum convene a multidisciplinary group of experts to create a new section in the kidney transplantation guidelines addressing the collaborative management of parathyroid disease in transplantation candidates.

Objective: Consensus guidelines recommend that intensive care unit (ICU) patients with blood glucose (BG) levels >180 mg/dL receive continuous intravenous insulin (CII). The effectiveness of CII at controlling BG levels among patients who are eating relative to those who are eating nothing by mouth (nil per os; NPO) has not been described. Methods: We conducted a retrospective cohort study of 260 adult patients (156 eating, 104 NPO) admitted to an ICU between January 1, 2014, and December 31, 2014, who received CII. Patients were excluded for a diagnosis of diabetic ketoacidosis or hyperglycemic hyperosmolar nonketotic syndrome, admission to an obstetrics service, or receiving continuous enteral or parenteral nutrition. Results: Among 22 baseline characteristics, the proportion of patients receiving glucocorticoid treatment (GCTx) (17.3% eating, 37.5% NPO; P<.001) and APACHE II score (15.0 ± 7.5 eating, 17.9 ± 7.9 NPO; P = .004) were significantly different between eating and NPO patients. ⋯ However, eating patients showed greater glucose variability (coefficient of variation 23.1 ± 1.0 eating, 21.2 ± 1.0 NPO; P = .034). Conclusion: Eating may not adversely affect BG levels of ICU patients receiving CII. Whether or not prandial insulin improves glycemic control in this setting should be studied. Abbreviations: BG = blood glucose; CII = continuous insulin infusion; CV = coefficient of variation; HbA1c = hemoglobin A1c; ICU = intensive care unit; NPO = nil per os; PDWMBG = patient day weighted mean blood glucose.

Objective: Due to a lack of typical clinical manifestations and physiologic changes in calcium metabolism during pregnancy, primary hyperparathyroidism (PHPT) during pregnancy is commonly underdiagnosed, and treatment during this unique period presents a clinical challenge. Hence, the aim of the present study was to summarize the cases of 8 pregnant patients with PHPT who were treated at our center to provide better clinical insight into this condition. Methods: Our study comprised a retrospective analysis of 8 pregnant PHPT patients and a control group of 22 age-matched, nonpregnant PHPT patients during the same period. Clinical manifestations, biochemical indices, pathologic types, therapeutic strategies, and pregnancy outcomes were compiled, and 25 patients were screened for germline mutations in the MEN1, CDC73, and CaSR genes. Results: The most-common symptoms in the pregnancy group involved the gastrointestinal tract (GIT) in 7/8 cases (87.5%), followed by urinary system involvement (50%) and joint pain (50%). ⋯ In addition, 2 of 5 pregnant PHPT patients were found to carry MEN1 mutations, whereas no mutations were detected in any of the 20 nonpregnant patients. Conclusion: In this case series of PHPT during pregnancy, the most-common complaint of GIT symptoms may be easily confused with pregnancy reactions, which might contribute to the under- or misdiagnosis of this clinical entity. Patients who did not receive surgical treatment during pregnancy had high incidences of fetal/neonatal complications and worse pregnancy outcomes. Abbreviations: CaSR = calcium-sensing receptor; CDC73 = cell division cycle 73; GIT = gastrointestinal tract; MEN = multiple endocrine neoplasia; PHPT = primary hyperparathyroidism; PTH = parathyroid hormone; SCa = serum calcium.

Objective: Macrosomia is closely associated with gestational diabetes mellitus (GDM) but its relationship with maternal intermediate state gestational blood glucose (ISGBG; normal fasting blood glucose and 7.8 mmol/L <1 hour blood glucose [BG] <10 mmol/L or 6.7 mmol/L <2 hour BG <8.5 mmol/L) is unclear. Here, we analyzed the clinical characteristics and pregnancy outcomes and explored risk factors for macrosomia in women with ISGBG. Methods: A total of 847 women with normal glucose tolerance gestation, 330 with ISGBG, and 99 with GDM were included. Maternal and fetal clinical data were collected and 3-point BG following oral glucose tolerance test, fasting insulin, glycated hemoglobin, and blood lipids profile were measured. Results: The incidence rate of macrosomia among the neonates of women with ISGBG was as high as 10.9%. ⋯ The risk of macrosomia in pregnant women with prepregnancy BMI <25 kg/m2 or BMI ≥25 kg/m2 and eGWG was 3.39 and 3.27 times, respectively. Conclusion: The incidence rate of macrosomia is increased in women with ISGBG and eGWG is the strongest independent risk factor. In order to reduce the risk for macrosomia, timely lifestyle intervention to promote appropriate weight gain during pregnancy deserves evaluation.

Objective: Most acute-care hospitals have transitioned from sliding-scale to basal-bolus insulin therapy to manage hyperglycemia during hospitalization, but there is limited scientific evidence demonstrating better short-term clinical outcomes using the latter approach. The present study sought to determine if using basal-bolus insulin therapy favorably affects these outcomes in noncritical care settings and, if so, whether the magnitude of benefit differs in patients with known versus newly diagnosed type 2 diabetes. Methods: This natural experiment compared outcomes in 10,120 non-critically ill adults with type 2 diabetes admitted to an academic teaching hospital before and after hospital-wide implementation of a basal-bolus insulin therapy protocol. A group of 30,271 inpatients without diabetes (type 1 or 2) served as controls. ⋯ The absence of effect in previously diagnosed patients was observed in spite of a 32% decline (from 3.7% to 2.5%) in the proportion of inpatient days with hypoglycemia <70 mg/dL (P<.01) and a 16% decline (from 13.5% to 11.3%) in the proportion of days with hyperglycemia >300 mg/dL (P<.01). Conclusion: Despite achieving significant reductions in both hyperglycemia and hypoglycemia, use of basal-bolus insulin therapy to manage hyperglycemia in non-critically ill hospitalized patients did not improve short-term clinical outcomes, except in the small minority of patients with newly diagnosed diabetes. The optimal management of hyperglycemia for improving these outcomes has yet to be determined. Abbreviation: ICD-9 = International Classification of Diseases-Ninth Revision.
