The Effect of Gender-Affirming Hormone Therapy on the Risk of Subclinical Atherosclerosis in the Transgender Population: A Systematic Review

ObjectiveThe impact of gender-affirming hormone therapy (GAHT) on cardiovascular (CV) health is still not entirely established. A systematic review was conducted to summarize the evidence on the risk of subclinical atherosclerosis in transgender people receiving GAHT.MethodsA systematic review was performed following Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, and data were searched in PubMed, LILACS, EMBASE, and Scopus databases for cohort, case-control, and cross-sectional studies or randomized clinical trials, including transgender people receiving GAHT. Transgender men and women before and during/after GAHT for at least 2 months, compared with cisgender men and women or hormonally untreated transgender persons. Studies reporting changes in variables related to endothelial function, arterial stiffness, autonomic function, and blood markers of inflammation/coagulation associated with CV risk were included.ResultsFrom 159 potentially eligible studies initially identified, 12 were included in the systematic review (8 cross-sectional and 4 cohort studies). Studies of trans men receiving GAHT reported increased carotid thickness, brachial-ankle pulse wave velocity, and decreased vasodilation. Studies of trans women receiving GAHT reported decreased interleukin 6, plasminogen activator inhibitor-1, and tissue plasminogen activator levels and brachial-ankle pulse wave velocity, with variations in flow-mediated dilation and arterial stiffness depending on the type of treatment and route of administration.ConclusionsThe results suggest that GAHT is associated with an increased risk of subclinical atherosclerosis in transgender men but may have either neutral or beneficial effects in transgender women. The evidence produced is not entirely conclusive, suggesting that additional studies are warranted in the context of primary prevention of CV disease in the transgender population receiving GAHT.Systematic Review RegistrationPROSPERO, identifier CRD42022323757.     

The Effect of Gender-Affirming Hormone Therapy on Serum Creatinine in Transgender Individuals

ObjectiveTo describe the changes in serum creatinine (Cr) levels after the initiation of gender-affirming hormone therapy (GAHT) in transgender individuals to better understand the expected changes and interpretation of laboratory values in this population.MethodsA retrospective chart review of all adult transgender patients initiated on GAHT at Mayo Clinic from January 2011 to October 2019 was completed. Laboratory values were obtained prior to initiating GAHT and at 3, 6, and 12 months after initiating GAHT. Baseline Cr values were compared with Cr values at 3, 6, and 12 months after initiating GAHT in transgender men (TM) on testosterone and transgender women (TW) on estradiol and antiandrogens.ResultsA total of 84 TW (median age of 30 years) and 24 TM (median age of 23 years) were included for analysis. Following a matched pair analysis of TW, Cr values were found to be significantly decreased by ?0.03 at 3 months (P = .04), ?0.10 at 6 months (P < .01), and ?0.07 at 12 months (P < .01) compared with baseline values. Following a matched pair analysis of TM, Cr values were found to be significantly increased, on average, by 0.14 at 3 months (P = .04), 0.21 at 6 months (P = .016), and 0.15 at 12 months (P = .003) compared with baseline values.ConclusionIn TW and TM, a change in Cr level was seen as early as 3 months toward their affirmed gender after initiating GAHT. Clinicians can use Cr levels established at 6 months as new baseline values, as these changes continue to persist up to 12 months.     

Assessing and Addressing the Risk of Venous Thromboembolism Across the Spectrum of Gender Affirming Care: A Review

ObjectiveAccumulating evidence demonstrates that gender affirming hormone therapy (GAHT) improves mental health outcomes in transgender persons. Data specific to the risks associated with GAHT for transgender persons continue to emerge, allowing for improvements in understanding, predicting, and mitigating adverse outcomes while informing discussion about desired effects. Of particular concern is the risk of venous thromboembolism (VTE) in the context of both longitudinal GAHT and the perioperative setting. Combining what is known about the risk of VTE in cisgender individuals on hormone therapy (HT) with the evidence for transgender persons receiving HT allows for an informed approach to assess underlying risk and improve care in the transgender community.ObservationsHormone formulation, dosing, route, and duration of therapy can impact thromboembolic risk, with transdermal estrogen formulations having the lowest risk. There are no existing risk scores for VTE that consider HT as a possible risk factor. Risk assessment for recurrent VTE and bleeding tendencies using current scores may be helpful when assessing individual risk. Gender affirming surgeries present unique perioperative concerns, and certain procedures include a high likelihood that patients will be on exogenous estrogens at the time of surgery, potentially increasing thromboembolic risk.Conclusions and RelevanceWithholding GAHT due to potential adverse events may cause negative impacts for individual patients. Providers should be knowledgeable about the management of HT in transgender individuals of all ages, as well as in the perioperative setting, to avoid periods in which transgender individuals are off GAHT. Treatment decisions for both anticoagulation and HT should be individualized and tailored to patients’ overall goals and desired outcomes, given that the physical and mental health benefits of gender affirming care may outweigh the risk of VTE.     

Serum Hormone Concentrations in Transgender Individuals Receiving Gender-Affirming Hormone Therapy: A Longitudinal Retrospective Cohort Study

ObjectiveTo examine the association of various gender-affirming hormone therapy regimens with blood sex hormone concentrations in transgender individuals.MethodsThis retrospective study included transgender people receiving gender-affirming hormone therapy between January 2000 and September 2018. Data on patient demographics, laboratory values, and hormone dose and frequency were collected. Nonparametric tests and linear regression analyses were used to identify factors associated with serum hormone concentrations.ResultsOverall, 196 subjects (134 transgender women and 62 transgender men), with a total of 941 clinical visits, were included in this study. Transgender men receiving transdermal testosterone had a significantly lower median concentration of serum total testosterone when compared with those receiving injectable preparations (326.0 ng/dL vs 524.5 ng/dL, respectively, P = .018). Serum total estradiol concentrations in the transgender women were higher in those receiving intramuscular estrogen compared with those receiving oral and transdermal estrogen (366.0 pg/mL vs 102.0 pg/mL vs 70.8 pg/mL, respectively, P < .001). A dose-dependent increase in the hormone levels was observed for oral estradiol (P < .001) and injectable testosterone (P = .018) but not for intramuscular and transdermal estradiol. Older age and a history of gonadectomy in both the transgender men and women were associated with significantly higher concentrations of serum gender-affirming sex hormones.ConclusionIn the transgender men, all routes and formulations of testosterone appeared to be equally effective in achieving concentrations in the male range. The intramuscular injections of estradiol resulted in the highest serum concentrations of estradiol, whereas transdermal estradiol resulted in the lowest concentration. There was positive relationship between both oral estradiol and injectable testosterone dose and serum sex hormone concentrations in transgender people receiving GAHT.     

Risk Assessment and Coronary Artery Calcium Scoring in Transgender and Gender-Diverse Individuals Receiving Gender-Affirming Hormone Therapy

ObjectiveTo evaluate cardiovascular risk factors and prevalent coronary artery disease (CAD) using Coronary Artery Calcium (CAC) scoring in transgender and gender-diverse (TGD) individuals receiving gender-affirming hormone therapy (GAHT) and compare the CAC scores of TGD individuals with those of the general population.MethodsTGD individuals aged ≥30 years, without known risk factors for cardiovascular disease (CVD), other than tobacco use and family history of CVD, on GAHT were recruited, and baseline information, including metabolic parameters, was collected. CAC scores were obtained and compared with those of a cisgender age-matched population.ResultsOf 25 transwomen recruited, 24 underwent CAC scans. Of them, 2 (8.3%) had a CAC score of >0 to 99 and 1 (4.1%) had a CAC score of ≥100. Of 22 transmen recruited, 16 underwent CAC scans. Of them, 26 (12.5%) had a CAC score of >0 to 99 and none had a CAC score of ≥100. Framingham Risk Scores were not correlated with the presence of CAC.ConclusionThe presence of CAC in this small cohort of TGD individuals on GAHT was similar to that in the cisgender age-matched population. CAC scoring is a means to assess the prevalence of CAD in TGD individuals and identify those in whom aggressive risk reduction is indicated.     

Potassium Concentrations in Transgender Women Using Spironolactone: A Retrospective Chart Review

ObjectiveTo assess the incidence of hyperkalemia in transgender women using spironolactone.MethodsThis was a retrospective chart review of transgender women who received gender-affirming hormone therapy that included spironolactone between January 2000 and September 2018. Forty-four participants who had paired potassium concentrations documented and were on spironolactone were included and analyzed. Study outcomes included the incidence of hyperkalemia (serum potassium concentrations > 5.0 mmol/L), the relationship between the duration of treatment and degree of hyperkalemia, and difference between serum potassium concentrations at the beginning of spironolactone treatment versus last serum potassium concentrations.ResultsThe median age of the participants was 36.5 years. The cohort was predominantly non-Hispanic White (32/44). No serum potassium concentration was >5.5 mmol/L, and all participants had serum creatinine level of <2 mg/dL. Median duration of treatment was 25 months (range 2-92 months) and 140 potassium measurements were available. The mean potassium concentration (3.87 mmol/L) before the initiation of spironolactone was lower than the mean potassium concentration (4.03 mmol/L) while on spironolactone (mean difference, 0.16 mmol/L, P = .013). The regression β, that is, the average change in potassium concentration per 1 additional month of treatment duration, was ?.001 (95% CI [?.004, .001]; P = .255) signifying no relation between treatment duration and spironolactone use.ConclusionNo participant had laboratory evidence of significant hyperkalemia (K > 5.5 mmol/L) after initiation of spironolactone. Frequent measurement of potassium concentrations might be unnecessary in transgender women taking spironolactone in patients with serum creatinine levels of <2 mg/dL.     

Cardiovascular Health Maintenance in Aging Individuals: The Implications for Transgender Men and Women on Hormone Therapy

ObjectiveTo review screening guidelines for cardiometabolic disease in aging patients and review literature describing the effect of hormone therapy (HT) on several key cardiometabolic processes to inform providers caring for older transgender individuals.MethodsA traditional literature review was performed using PubMed and Google Scholar databases.ResultsThe risk of cardiovascular disease increases with age. Exogenous sex hormones may interact with hormone-dependent metabolic pathways and affect some biochemical assays, but they do not necessarily impact clinical outcomes. While long-term HT is associated with an increased risk of some adverse cardiovascular outcomes, modern treatment regimens minimize this risk.ConclusionScreening for cardiometabolic derangements and risk reduction are important for all aging individuals. Currently, there is insufficient evidence to propose separate screening recommendations for transgender individuals on long-term HT. Aging transgender men and women should be monitored for cardiovascular disease in much the same way as their cisgender counterparts.     

Minimizing Venous Thromboembolism in Feminizing Hormone Therapy: Applying Lessons From Cisgender Women and Previous Data

ObjectiveTo review he impact of estrogen-containing feminizing hormone regimens on transgender individuals’ risk for VTE.MethodsWe evaluated VTE risk by screening 1170 relevant studies published from 1994 to 2020, focusing on meta-analysis data.ResultsThe type of oral estrogen, route of administration, patient demographics, and comorbidities may affect the risk of VTE. Venous thrombosis is the most common vascular complication associated with HT.ConclusionConjugated equine estrogens and 17-β estradiol appear to be safer than oral ethinyl estradiol. Transdermal estrogen formulations appear to be the least thrombogenic estrogens. Estrogens used concomitantly with progestins increase the risk of VTE compared to estrogens alone.To date, there are no data to demonstrate the benefit of holding HT prior to vaginoplasty or other gender affirming surgeries. For most young, healthy transgender women, there is little risk of VTE with HT, while older patients with risk factors should be discussed case by case.     

Pharmacokinetics of Sublingual Versus Oral Estradiol in Transgender Women

ObjectiveTo investigate the pharmacokinetics of 17β-estradiol (E2) administered orally versus those of 17β-E2 administered sublingually in transgender women.MethodsSingle doses of 17β-E2 were administered orally (1 mg) to 10 transgender women and then sublingually (1 mg) after a 1-week washout period. Blood samples were collected at baseline (0 hour) and at 1, 2, 3, 4, 6, and 8 hours after dosing. The samples were frozen and analyzed using liquid chromatography mass spectrometry (LC-MS/MS) and immunoassay.ResultsThe results demonstrated that sublingual E2 had a significantly higher peak serum E2 concentration of 144 pg/mL, measured using LC-MS/MS, compared with an oral E2 concentration of 35 pg/mL, measured using LC-MS/MS (P = .003). Sublingual E2 peaked at 1 hour and oral E2 peaked at 8 hours, as measured using LC-MS/MS. The area under the curve (AUC) (0-8 hours) for sublingual E2, measured using LC-MS/MS, was 1.8-fold higher than the AUC (0-8 hours) for oral E2, measured using LC-MS/MS. Additionally, sublingual E2 was found to have an increased E2-to-estrone ratio at all time points (1.1 ± 1.0 vs 0.7 ± 0.4, P ≤ .0001), the clinical significance of which is unclear.ConclusionOral E2 administered sublingually has a different pharmacokinetic profile, with higher serum E2 levels and AUC (0-8 hours) than traditionally administered oral E2. Multidaily dosing may be necessary to suppress testosterone levels with sublingual E2. The appropriate dosing, efficacy, and safety of sublingual E2, compared with those of other E2 preparations, are unknown.     

Phenotype Prevalence and Health-Related Quality of Life of Lebanese Women With Polycystic Ovary Syndrome

ObjectivePolycystic ovary syndrome (PCOS) is one of the most common endocrine disorders. Our study aimed to assess, for the first time, the phenotype prevalence and the health-related quality of life of Lebanese women with PCOS.MethodsThis was a cross-sectional study conducted on 322 Lebanese women with PCOS, using a questionnaire containing sociodemographic data, comorbidities, disease-related clinical questions, and the validated PCOS questionnaire (PCOSQ). The quality of life mean scores and phenotypes were compared and correlated among the different sociodemographic data, comorbidities, and disease-related questions.ResultsPhenotype A (67%) was the most common phenotype. High waist circumference and higher Body Mass Index (BMI) were reported mostly in classic phenotypes in comparison with nonclassic (P < .05). The mean total score of all PCOSQ domains was 3.61 ± 1.60. The mean score for each domain (from the greatest to the least serious concern) was menstrual problems (3.31 ± 1.26), emotion (3.33 ± 1.22), weight (3.41 ± 2.12), body hair (3.86 ± 1.79), and infertility (4.15 ± 1.61). Age was negatively correlated only to weight domain score (r = ?0.17, P = .002). BMI was associated only with emotion and weight domain scores (P = .017 and P < .001, respectively). A bigger impairment in nearly all subscales of the PCOSQ in patients presenting with abdominal obesity, glucose intolerance, and increased blood pressure was noted (P < .05).ConclusionMost Lebanese women with PCOS present phenotype A and have a serious impairment in their health-related quality of life, particularly in the menstrual and emotional domains. This highlights the need for community and individual support.     

Does a MediDiet With Additional Extra Virgin Olive Oil and Pistachios Reduce the Incidence of Gestational Diabetes?

ObjectiveThe present study aimed to evaluate gestational diabetes mellitus (GDM) incidence in pregnant women following the Mediterranean diet (MedDiet) with the addition of extra virgin olive oil (EVOO) and pistachios.MethodsA total of 560 pregnant patients were enrolled in the present study. The MedDiet was introduced in both the interventional group (IG) and the control group. The women in the IG received 40 mL of EVOO every day along with 25 to 30 g of roasted pistachios. The incidence of GDM was recorded along with specific maternal and neonatal outcomes.ResultsThe nutritional scores and MedDiet adherence screener scores were not statistically different between the groups at baseline, but the difference was statistically significant and higher in the IG at 24 to 28 weeks (P = .001) and at 36 to 38 weeks (P = .001). GDM was diagnosed in 51 (20.4%) women in the control group and 34 (13.6%) women in the IG. The MedDiet significantly reduced GDM incidence (P = .02) after adjusting for confounding factors.ConclusionThe present study shows that dietary intervention in pregnant women, including a MedDiet and increased consumption of EVOO and pistachios, decreases the incidence of GDM.     

Risk of Breast Cancer in Females With Hypothyroidism: A Nationwide,Population-Based,Cohort Study

ObjectivesThe results of studies investigating the relationship between breast cancer and hypothyroidism vary greatly from study to study. In this study, we analyzed a large and reliable, population-based database to gain a better understanding of the correlation.MethodsThis retrospective cohort study analyzed patients with hypothyroidism between January 1, 2000 and December 31, 2012 (hypothyroidism cohort) from the Longitudinal Health Insurance Database 2000 in Taiwan. For each woman with hypothyroidism, 1 woman without a history of breast cancer was randomly selected from the Longitudinal Health Insurance Database 2000 and frequency matched (1:4) with women without hypothyroidism by age and index year of hypothyroidism. The study outcome was the diagnosis of breast cancer during a 12-year follow-up period.ResultsIn this study, 6665 women with hypothyroidism and 26 660 women without hypothyroidism were identified. The hypothyroidism cohort had a significantly higher risk of breast cancer than the nonhypothyroidism cohort (adjusted hazard ratio [aHR] 1.69 [95% CI, 1.15-2.49]; P = .01), especially in the group aged 40 to 64 years (aHR 2.07 [95% CI, 1.32-3.23]; P = .01). Women in the hypothyroidism cohort taking levothyroxine for a duration ˃588 days showed a significantly decreased risk of breast cancer (aHR 0.37 [95% CI, 0.19-0.71]; P = .003).ConclusionWomen with hypothyroidism are at a higher risk of breast cancer than those without hypothyroidism. Levothyroxine may reduce the risk of breast cancer in a woman with hypothyroidism.     

Increasing Gap Between Thyroid Cancer Incidence and Mortality in Urban Shanghai,China: An Analysis Spanning 43 Years

ObjectiveTo examine the secular trends of thyroid cancer incidence and mortality and to estimate the proportion of thyroid cancer cases potentially attributable to overdiagnosis.MethodsData on thyroid cancer cases from 1973 to 2015 were obtained from the Shanghai Cancer Registry. The average annual percent change (AAPC) was evaluated using the joinpoint regression analysis. The age, period, and birth cohort effects were assessed using an age-period-cohort model. The overdiagnosis of thyroid cancer cases was estimated based on the difference between observed and expected incidences using the rates of Nordic countries as reference.ResultsFrom 1973 to 2015, the number of thyroid cancer cases was 23 117, and 75% of the patients were women. The age-standardized rates were seven- to eightfold higher from 2013 to 2015 than from 1973 to 1977. Compared with relatively stable mortality, thyroid cancer incidence was dramatically increased from 2002 to 2015 in both sexes, with significant trends (men: AAPC = 21.84%, 95% CI: 18.77%-24.98%, P < .001; women: AAPC = 18.55%, 95% CI: 16.49%-20.64%, P < .001). The proportion of overdiagnosis has gradually increased over time, rising from 68% between 2003 and 2007 to more than 90% between 2013 and 2015. This increasing trend appeared to be similar between men and women.ConclusionAn increasing gap between thyroid cancer incidence and mortality was observed in Shanghai, and overdiagnosis has contributed substantially to the rise of incidence, which calls for an urgent update on the practice of thyroid examination.     

Comparison of the Subcutaneous and Intramuscular Estradiol Regimens as Part of Gender-Affirming Hormone Therapy

ObjectiveGender-affirming hormone therapy guidelines describe the estradiol (E2) doses for intramuscular (IM), but not subcutaneous (SC), routes. The objective was to compare the SC and IM E2 doses and hormone levels in transgender and gender diverse individuals.MethodsThis is a retrospective cohort study at a single-site tertiary care referral center. Patients were transgender and gender diverse individuals who received injectable E2 with at least 2 E2 measurements. The main outcomes were the dose and serum hormone levels between the SC and IM routes.ResultsThere were no statistically significant differences in age, body mass index, or antiandrogen use between patients on SC (n = 74) and those on IM (n = 56). The weekly doses of SC E2, 3.75 mg (IQR, 3-4 mg), were statistically significantly lower than those of IM E2, 4 mg (IQR, 3-5.15 mg) (P =.005); however, the E2 levels achieved were not significantly different (P =.69), and the testosterone levels were in the cisgender female range and not significantly different between routes (P =.92). Subgroup analysis demonstrated significantly higher doses in the IM group when the E2 and testosterone levels were >100 pg/mL and <50 ng/dL, respectively, with the presence of the gonads or use of antiandrogens. Multiple regression analysis demonstrated that the dose was significantly associated with the E2 levels after adjusting for injection route, body mass index, antiandrogen use, and gonadectomy status.ConclusionBoth the SC and IM E2 achieve therapeutic E2 levels without a significant difference in the dose (3.75 vs 4 mg). SC may achieve therapeutic levels at lower doses than IM .     

Osilodrostat: A Review of Recent Clinical Studies and Practical Recommendations for its Use in the Treatment of Cushing Disease

ObjectiveCushing disease (CD) is characterized by chronic hypercortisolism caused by an adrenocorticotropic hormone-secreting pituitary adenoma. Surgery remains the first-line treatment option; however, medical therapy is essential if surgery is contraindicated or fails to achieve remission or when recurrence occurs after surgical remission. Osilodrostat (Isturisa), a novel steroidogenic inhibitor, is now approved for the treatment of CD in the United States and Cushing syndrome in Europe. Herein, we review pharmacology and data on the efficacy, safety, and clinical use of osilodrostat and provide guidance on its use in treating patients with CD.MethodsWe reviewed the literature and published clinical trial data of osilodrostat use in patients with Cushing syndrome. Detailed information related to the clinical assessment of osilodrostat use, potential drug-to-drug interactions, drug initiation, dose titration, and the monitoring of drug tolerability were discussed.ResultsClinical trial data demonstrated that osilodrostat, by virtue of inhibiting 11-β hydroxylase, potently and rapidly decreased the 24-hour urinary free cortisol levels and sustained these reductions, with improved glycemia, blood pressure, body weight, and quality of life as well as lessened depression. Osilodrostat may interact with certain drugs, resulting in QT prolongation, which requires careful assessment of concomitant medications and periodic monitoring using electrocardiogram, respectively. The common adverse effects include adrenal insufficiency, hypokalemia, edema, and hyperandrogenic symptoms, which can be minimized using a slower up-titration dosing regimen.ConclusionOsilodrostat is an effective, new treatment option for CD, with positive effects on cardiovascular and quality of life parameters as well as tolerable adverse effects. This article provides a review of the pharmacology of osilodrostat and offers practical recommendations on the use of osilodrostat to treat CD.     

Association of Early Pregnancy Free and Total Triiodothyronine With the Subsequent Risk of Gestational Diabetes Mellitus

ObjectiveTo estimate the association of free triiodothyronine (FT3) and total triiodothyronine (TT3) in early pregnancy and subsequent gestational diabetes mellitus (GDM) risk and define appropriate TT3 thresholds for GDM screening.MethodsThis investigation is a hospital-based cohort study of pregnant women submitted to a universal thyroid function test before 24 weeks of gestation. GDM was diagnosed according to a 75-g oral glucose tolerance test. The association of maternal high FT3 and TT3 levels in early pregnancy with the risk of GDM was estimated using logistic regression. The potential nonlinear association was probed by the restricted cubic spline curve method.ResultsA total of 27 184 pregnant women and 3073 GDM cases were included in the analysis. FT3 and TT3 were associated with an increased subsequent risk of GDM in a nonlinear fashion. The adjusted odds ratios were 1.59 (95% confidence interval, 1.50-1.68) and 2.80 (95% confidence interval, 2.46-3.18) for FT3 and TT3 continuous levels, respectively. Associations were strong in euthyroid women, showed heterogeneity in women with mild thyroid dysfunction, and lacked in patients with overt hypothyroidism and hyperthyroidism. The TT3 thresholds of 1.5 and 2.0 ng/mL between 7 and 12 weeks of gestation and 1.6 and 2.1 ng/mL for 13 to 23 weeks of gestation effectively distinguished the subsequent risk of GDM.ConclusionThe increased FT3 and TT3 levels in early pregnancy were associated with a subsequent higher risk of GDM. These findings provide measures for early detection and potential prevention of GDM.     

Sexual Dysfunction in Sheehan Syndrome

ObjectiveThe study was done to objectively document the sexual function in Sheehan syndrome (SS). SS is not an uncommon cause of hypopituitarism in developing countries. The lack of sex steroids from both ovaries and adrenal glands could lead to sexual dysfunction in SS. Sexual function is a neglected aspect of health in women in developing countries, although it greatly contributes toward the quality of life and feeling of well-being. Objective documentation of sexual function in SS is limited.MethodsThirty-two subjects with SS on conventional therapy (except growth hormone) were evaluated. SS was diagnosed as per standard criteria. Sexual function was assessed by validated questionnaires using the Female Sexual Function Index (FSFI). Thirty healthy women of a similar age range and socioeconomic background were included as comparators.ResultsThe mean age (±SD) of the study population and healthy controls was 39.9 (±8.6) years and 38.2 (±6.8) years, respectively. The median interval between inciting events and diagnosis of SS was 8.3 years (interquartile range, 5.2-13.5 years). Thirty subjects were sexually active. Of the 30 subjects, 28 (93%) had sexual dysfunction, that is, an FSFI score of ≤26.55. The median total FSFI scores of subjects with SS and controls were 20.8 and 29.05, respectively, (P = .001). There was a statistically significant difference for individual parameters of sexual function, including desire, arousal, lubrication, orgasm, and satisfaction, between those with SS and controls. However, the pain during intercourse was not different. FSFI score in subjects with SS was not correlated with any endocrine parameter or duration of the disease since diagnosis.ConclusionSexual dysfunction is very common, affecting >90% of subjects with SS.     

Efficacy and Safety of Analog Insulin in Comparison With Human Insulin for Hyperglycemia in Hospitalized Patients With Acute Stroke: A Randomized,Open-Label,Single-Center Trial

ObjectiveTo assess the efficacy and safety of analog insulins in comparison with human insulins for hyperglycemia in hospitalized patients with acute stroke.MethodsIn this single-center, open-label, randomized trial, 102 patients (age 59.4 ± 11.7 years, 54 women) admitted with acute stroke (52 ischemic, 50 hemorrhagic) and hyperglycemia were assigned to analog insulin (n = 52) or human insulin (n = 50) group during February to June 2021. Insulin was initiated and titrated according to the predefined standard protocol. The capillary blood glucose (BG) level was monitored by standardized glucometers. The primary outcomes were mean daily BG and the number of hypoglycemic events.ResultsBetween the 2 treatment groups, there was no significant difference in the mean daily BG (P >.05 for all days) or in the frequency of hypoglycemic episodes (P =.727). Four participants experienced severe hypoglycemia; all were receiving human insulin (P =.054). In the analog insulin group, there was a tendency toward lower daily total requirement for insulin (P =.053). The difference in bolus insulin dose was significantly lower in the analog insulin group (P =.029), but the difference in basal insulin dose was similar (P =.167). Between the 2 groups, there were no significant differences in the hospital mortality rate, modified Rankin Scale score on outcome, or length of hospital stay (P =.729,.658, and.918, respectively).ConclusionHospitalized patients acute stroke and hyperglycemia exhibited similar mean BG but a trend of lower incidence of severe hypoglycemia when treated with analog insulins in comparison with human insulin.     

Hemodynamic monitoring by intracardiac impedance measured by cardiac resynchronization defibrillators: Evaluation in a controlled clinical setting (BIO.Detect HF II study)

BackgroundIn patients with cardiac resynchronization therapy defibrillators (CRT-Ds), intracardiac impedance measured by dedicated CRT-D software may be used to monitor hemodynamic changes. We investigated the relationship of hemodynamic parameters assessed by intracardiac impedance and by echocardiography in a controlled clinical setting.MethodsThe study enrolled 68 patients (mean age, 66 ± 9 years; 74% males) at 12 investigational sites. The patients had an indication for CRT-D implantation, New York Heart Association class II/III symptoms, left ventricular ejection fraction 15%–35%, and a QRS duration ≥150 ms. Two months after a CRT-D implantation, hemodynamic changes were provoked by overdrive pacing. Intracardiac impedance was recorded at rest and at four pacing rates ranging from 10 to 40 beats/min above the resting rate. In parallel, echocardiography measurements were performed. We hypothesized that a mean intra-individual correlation coefficient (r_mean) between stroke impedance (difference between end-systolic and end-diastolic intracardiac impedance) measured by CRT-D and the aortic velocity time integral (i.e., stroke volume) determined by echocardiography would be significantly larger than 0.65.ResultsThe hypothesis was evaluated in 40 patients with complete data sets. The r_mean was 0.797, with a lower confidence interval bound of 0.709. The study hypothesis was met (p = 0.007). A stepwise reduction of stroke impedance and stroke volume was observed with increasing heart rate.ConclusionsIntracardiac impedance measured by implanted CRT-Ds correlated well with the aortic velocity time integral (stroke volume) determined by echocardiography. The impedance measurements bear potential and are readily available technically, not requiring implantation of additional material beyond standard CRT-D system.
