ABSTRACT

BACKGROUND: The antihypertensive efficacy of fimasartan was assessed based on the transition rate from a combination of calcium channel blockers (CCB) and angiotensin receptor blockers (ARB) to three-drug combination therapy, as compared to other ARBs. METHODS: This nationwide cohort study used data obtained from the Korean National Health Insurance Service database. Patients who had received national health checkups within 2 years prior to January 1, 2017, and were concurrently prescribed ARBs and CCBs for > 30 days during the 6 months from January 1, 2017, to June 30, 2017 were included in the study. Patients were categorized into the 'fimasartan group' (those prescribed fimasartan) and the 'non-fimasartan group' (those prescribed ARBs other than fimasartan). The index date was set as the last day of a 30-day prescription period for ARBs and CCBs, with a subsequent 2.5-year follow-up to observe the potential addition of a third drug, such as beta-blockers or diuretics. RESULTS: The study included 34,422 patients with a mean age of 60.3 years and 58.3% being male. The fimasartan group constituted 2.7% (n = 928) of the total, and the non-fimasartan group, 97.3% (n = 33,494). During the follow-up period, 38 patients in the fimasartan group (14.3 per 1,000 person-years) and 3,557 patients in the non-fimasartan group (42.8 per 1,000 person-years) required additional antihypertensive medications. After multivariate adjustment for age, sex, diabetes mellitus, dyslipidemia, cancer, heart failure, systolic blood pressure, and diastolic blood pressure, the fimasartan group showed a significantly lower rate of adding a third medication (hazard ratio 2.68, 95% confidence interval 1.95-3.69) compared to that of the non-fimasartan group. CONCLUSIONS: Fimasartan is associated with a lower need for additional antihypertensive drugs compared to other ARBs. This implies its greater effectiveness in hypertension management, potentially enhancing cardiovascular outcomes, and minimizing polypharmacy.

ABSTRACT

PURPOSE: With laparoscopic sleeve gastrectomy (LSG) taking its place as the primary metabolic bariatric procedure in the past decade, de novo or persistent gastroesophageal reflux disease (GERD) has come into the spotlight as one of the most debilitating postoperative complications. Among the causes of GERD, intrathoracic migration (ITM) of the sleeve has become an understated yet significant phenomenon. This study aims to analyze the actual incidence of spontaneous ITM at our center, as well as its relationship to the baseline characteristics of patients and perioperative outcomes. MATERIALS AND METHODS: A retrospective chart review of 206 patients who had undergone LSG at our center from July 2019 to December 2022 was done. At 1-year follow-up, a non-enhanced abdominopelvic computed tomography (CT) scan and esophagogastroduodenoscopy (EGD) were performed, and these exams were repeated annually. Baseline characteristics and perioperative outcomes including the clinical disease course of GERD were compared. RESULTS: The incidence of ITM was 14% (n = 29). There was a significant correlation between ITM and postoperative reflux symptoms (p = 0.001). The mean duration of anti-reflux medication use was also significantly longer in the ITM group than in the no ITM group at 17 and 11 months, respectively (p = 0.004). A significantly higher number of patients in the ITM group were diagnosed with esophagitis on postoperative EGD than in the no ITM group (p = 0.002). CONCLUSION: The incidence of ITM using non-enhanced CT was 14%. ITM was significantly correlated to clinical reflux and EGD-confirmed esophagitis.

ABSTRACT

BACKGROUND: Hypertrophic cardiomyopathy (HCM) is a heterogeneous disorder with varying risks of clinical outcomes, including sudden cardiac death (SCD). We aimed to identify distinct phenotypes among patients with HCM in relation to SCD risk factors, interpret their clinical characteristics, and examine their outcomes. METHODS AND RESULTS: This retrospective study analyzed 1231 consecutive patients with HCM from 2 tertiary hospitals. We performed latent class analysis to categorize patients into phenotypic groups. Three distinct phenotypic groups were identified using latent class analysis. Group 1 (n=554) consisted of young patients with HCM with minimal SCD risk factors and favorable cardiac remodeling. Group 2 (n=114) comprised young patients with HCM and a high prevalence of SCD risk factors, whereas Group 3 (n=563) included older patients (median age, 68 years). Over a median 6.5-year follow-up, 34 SCD-related events, 131 cardiovascular events, 133 all-cause mortality events, and 70 noncardiovascular mortality events were observed. Group 2 exhibited the highest rate of SCD-related events (5-year SCD rate: Group 1 versus 2 versus 3: 0.8% versus 8.2% versus 4.0%, respectively, P<0.001), and cardiovascular events were more frequent in Groups 2 and 3 compared with Group 1. All-cause and noncardiovascular mortality were the most frequent in Group 3. A simplified decision tree was developed for the straightforward assignment of phenotypic group membership, demonstrating fair concordance. CONCLUSIONS: This study identified 3 distinct clinical phenotypes in patients with HCM, each associated with different SCD risks and outcomes. Data-driven phenotyping of patients with HCM offers effective risk stratification and may optimize patient management.

ABSTRACT

INTRODUCTION: Various strategies aim to better assess risks and refine prevention for patients with type 2 diabetes mellitus (T2DM), who vary in cardiovascular disease (CVD) risk. However, the prognostic value of personality and its association with lifestyle factors remain elusive. RESEARCH DESIGN AND METHODS: We identified 8794 patients with T2DM from the UK Biobank database between 2006 and 2010 and followed them up until the end of 2021. We assessed personality traits using the Big Five proxies derived from UK Biobank data: sociability, warmth, diligence, curiosity, and nervousness. Healthy lifestyle behaviors were determined from information about obesity, smoking status, and physical activity. The primary outcome was a composite of incident CVD, including myocardial infarction (MI), ischemic stroke (IS), atrial fibrillation (AF), and heart failure (HF). RESULTS: During a median follow-up of 13.6 years, a total of 2110 patients experienced CVDs. Among personality traits, diligence was significantly associated with a reduced risk of primary and secondary outcomes. The adjusted HRs with 95% CIs were: composite CVD, 0.93 (0.89-0.97); MI 0.90 (0.82-1.00); IS 0.83 (0.74-0.94); AF 0.92 (0.85-0.98); HF 0.84 (0.76-0.91). Healthy lifestyle behaviors significantly reduced the risk of composite CVDs in groups with high and low diligence. The findings of a structural equation model showed that diligence directly affected the risk of the primary outcome or indirectly by modifying lifestyle behaviors. CONCLUSION: This study revealed which personality traits can influence CVD risk during T2DM and how patients might benefit from adopting healthy lifestyle behaviors in relation to personality.

ABSTRACT

BACKGROUND: Patients with moderate or asymptomatic severe aortic stenosis (AS) are at risk of cardiovascular events. OBJECTIVES: The authors investigated the utility of cardiac magnetic resonance (CMR) to identify drivers of outcome in patients with moderate or asymptomatic severe AS. METHODS: A prospective, international, multicenter cohort (n = 457) of patients with moderate (aortic valve area [AVA]: 1.0-1.5 cm2) or asymptomatic severe AS (AVA ≤1.0 cm2 and NYHA functional class I-II) patients underwent CMR. Diffuse interstitial fibrosis and scar in the myocardium were analyzed with extracellular volume fraction (ECV%) and late gadolinium enhancement (LGE). The outcome was a composite of mortality and heart failure admission. RESULTS: Median ECV% was 26.6% (IQR: 24.4%-29.9%), and LGE was present in 31.5% (median 0.8%; IQR: 0.1%-1.7%). Greater AS severity was associated with greater left ventricular mass and diastolic dysfunction, but not with ECV% or LGE. During a median 5.7 years of follow-up, 83 events occurred. Patients with events had higher ECV% (median ECV% 26.3% vs 28.2%; P = 0.003). Patients in the highest ECV% tertiles (ECV% >28.6%) had worse outcomes both in the entire cohort and in those with NYHA functional class I moderate or severe AS, and ECV% was independently associated with outcome (adjusted HR: 1.05; P = 0.039). The ECV% had significant incremental prognostic value when added to parameters of AS severity and cardiac function, comorbidities, aortic valve replacement, and LGE (P < 0.05). CONCLUSIONS: Increased diffuse interstitial fibrosis of the myocardium is associated with poor outcomes in patients with moderate and asymptomatic severe AS and can help identify those who require closer surveillance for adverse outcomes.

ABSTRACT

BACKGROUND: Medical therapy for aortic stenosis (AS) remains an elusive goal. OBJECTIVES: This study sought to establish whether evogliptin, a dipeptidyl peptidase-4 inhibitor, could reduce AS progression. METHODS: A total of 228 patients (age 67 ± 11 years; 33% women) with AS were randomly assigned to receive placebo (n = 75), evogliptin 5 mg (n = 77), or evogliptin 10 mg (n = 76). The primary endpoint was the 96-week change in aortic valve calcium volume (AVCV) on computed tomography. Secondary endpoints included the 48-week change in active calcification volume measured using 18F-sodium fluoride positron emission tomography (18F-NaF PET). RESULTS: There were no significant differences in the 96-week changes in AVCV between evogliptin 5 mg and placebo (-5.27; 95% CI: -55.36 to 44.82; P = 0.84) or evogliptin 10 mg and placebo (-18.83; 95% CI: -32.43 to 70.10; P = 0.47). In the placebo group, the increase in AVCV between 48 weeks and 96 weeks was higher than that between baseline and 48 weeks (136 mm3; 95% CI: 108-163 vs 102 mm3; 95% CI: 75-129; P = 0.0485). This increasing trend in the second half of the study was suppressed in both evogliptin groups. The 48-week change in active calcification volume on 18F-NaF PET was significantly lower in both the evogliptin 5 mg (-1,325.6; 95% CI: -2,285.9 to -365.4; P = 0.008) and 10-mg groups (-1,582.2; 95% CI: -2,610.8 to -553.5; P = 0.0038) compared with the placebo group. CONCLUSIONS: This exploratory study did not demonstrate the protective effect of evogliptin on AV calcification. Favorable 18F-NaF PET results and possible suppression of aortic valve calcification with longer medication use in the evogliptin groups suggest the need for larger confirmatory trials.

ABSTRACT

BACKGROUND: Right ventricular (RV) systolic dysfunction is an established prognostic factor in patients with severe tricuspid regurgitation (TR). However, accurate assessment of RV systolic function using conventional echocardiography remains challenging. We investigated the accuracy of strain measurement using speckle tracking echocardiography (STE) for evaluating RV systolic function in patients with severe TR. METHODS: We included consecutive patients with severe TR who underwent echocardiography and cardiac magnetic resonance imaging (CMR) within 30 days between 2011 and 2023. Two-dimensional STE was used to measure RV free wall longitudinal strain (RVFWLS) and global longitudinal strain (RVGLS). These values were compared with the RV ejection fraction (RVEF) from CMR. RV systolic dysfunction was defined as a CMR-derived RVEF < 35%. RESULTS: A total of 87 patients with severe TR were identified during the study period. Among echocardiographic RV strain measurements, RVFWLS was the best correlate of CMR-derived RVEF (r = -0.37, P < 0.001), followed by RVGLS (r = -0.27, P = 0.012). Receiver operating characteristic (ROC) curve analysis revealed that RVFWLS provided better discrimination of RV systolic dysfunction, yielding an area under the ROC curve (AUC) of 0.770 (95% confidence interval [CI], 0.696-0.800) than RV fractional area change (AUC, 0.615; 95% CI, 0.500-0.859). CONCLUSIONS: In patients with severe TR, STE-derived RVFWLS showed the best correlation with RVEF on CMR and displayed superior discrimination of RV systolic dysfunction compared with the RV fractional area change. This study suggests the potential usefulness of STE in assessing RV systolic function in this population.

ABSTRACT

BACKGROUND: We assessed whether combinations of cardiometabolic risk factors independently predict coronary plaque progression (PP) and major adverse cardiovascular events in patients with stable coronary artery disease. METHODS: Patients with known or suspected stable coronary artery disease (60.9±9.3 years, 55.4% male) undergoing serial coronary computed tomography angiographies (≥2 years apart), with clinical characterization and follow-up (N=1200), were analyzed from the PARADIGM study (Progression of Atherosclerotic Plaque Determined by Computed Tomographic Angiography Imaging). Plaque volumes measured in coronary segments (≥2 mm in diameter) were summed to provide whole heart plaque volume (mm3) and percent atheroma volume (plaque volume/vessel volume×100; %) per patient at baseline and follow-up. Rapid PP was defined as a percent atheroma volume increase of ≥1.0%/y. Major adverse cardiovascular events included nonfatal myocardial infarction, death, and unplanned coronary revascularization. RESULTS: In an interscan period of 3.2 years (interquartile range, 1.9), rapid PP occurred in 341 patients (28%). At multivariable analysis, the combination of cardiometabolic risk factors defined as metabolic syndrome predicted rapid PP (odds ratio, 1.51 [95% CI, 1.12-2.03]; P=0.007) together with older age, smoking habits, and baseline percent atheroma volume. Among single cardiometabolic variables, high fasting plasma glucose (diabetes or fasting plasma glucose >100 mg/dL) and low HDL-C (high-density lipoprotein cholesterol; <40 mg/dL in males and <50 mg/dL in females) were independently associated with rapid PP, in particular when combined (odds ratio, 2.37 [95% CI, 1.56-3.61]; P<0.001). In a follow-up of 8.23 years (interquartile range, 5.92-9.53), major adverse cardiovascular events occurred in 201 patients (17%). At multivariable Cox analysis, the combination of high fasting plasma glucose with high systemic blood pressure (treated hypertension or systemic blood pressure >130/85 mm Hg) was an independent predictor of events (hazard ratio, 1.79 [95% CI, 1.10-2.90]; P=0.018) together with family history, baseline percent atheroma volume, and rapid PP. CONCLUSIONS: In patients with stable coronary artery disease, the combination of hyperglycemia with low HDL-C is associated with rapid PP independently of other risk factors, baseline plaque burden, and treatment. The combination of hyperglycemia with high systemic blood pressure independently predicts the worse outcome beyond PP.

ABSTRACT

Anti-phospholipid syndrome (APS) nephropathy is an autoimmune disease that is sometimes accompanied by systemic lupus erythematosus (SLE). Here, we report the use of rituximab to treat a case of APS nephropathy in a SLE patient with recurrent vascular thrombosis. A 52-year-old woman, who had been diagnosed with SLE 11 years earlier, was referred to a nephrology clinic for evaluation of azotaemia and proteinuria. She had experienced spontaneous abortion at 35 years of age. The patient had been diagnosed with right popliteal thrombosis at 39 years of age, and with left pulmonary artery thrombosis and SLE at 41 years of age. Before admission, she was undergoing anticoagulant and immunosuppressive therapies, with follow-up in the rheumatology clinic. At her last outpatient clinic visit before admission, she exhibited mild bilateral lower-limb pitting oedema, impaired renal function and proteinuria. Renal biopsy revealed arteriolar wall thickening, with thrombi in the capillary lumina and marked inflammatory cell infiltration in the interstitium. The patient was treated with warfarin and high-dose corticosteroids. Intravenous rituximab (500 mg) was also administered twice at a 4-week interval. Her renal function did not worsen any further, and her proteinuria decreased. Here we report the successful use of rituximab to treat APS nephropathy in a patient with SLE, who had progressive renal insufficiency.

ABSTRACT

AIMS: An association between obesity, metabolic abnormalities and clinical hypertrophic cardiomyopathy (HCM) expression has been reported. We investigated whether managing dyslipidaemia with fibrates could affect the clinical expression of HCM. METHODS: We screened patients who used fibrates between 2010 and 2017 from a nationwide database. After excluding patients with a history of HCM, we identified fibrate-user group (n = 412 823). We then constructed a 1:1 matched cohort of fibrate-naïve participants (n = 412 823). After a 1 year lag period, we identified the incident HCM cases for the following 5 years. RESULTS: During a median follow-up period of 3.96 years, we identified 454 incident clinical HCM cases. After adjusting for covariates, fibrate use was associated with a lower risk of clinical HCM expression [hazard ratio (HR) 95% confidence interval (CI): 0.763 (0.630-0.924)]. In subgroup analyses, fibrate use was associated with a reduced risk of clinical HCM expression in patients with a body mass index ≥25 kg/m2 and those with abdominal obesity [HR (95% CI): 0.719 (0.553-0.934) and 0.655 (0.492-0.872)], but not in those without obesity. Fibrate use was also associated with lower risks of incident clinical HCM in patients with triglyceride levels ≥150 mg/dL and those with metabolic syndrome [HR (95% CI): 0.741 (0.591-0.929) and 0.750 (0.609-0.923)], but not in their counterparts. Regarding lifestyle behaviours, fibrate use appeared to provide more prognostic benefits in patients who currently smoked, consumed alcohol or did not engage in regular physical activities. CONCLUSION: The use of fibrates is associated with a lower incidence of clinical HCM expression. This association was also more prominent in those with obesity, unhealthy metabolic profiles and poor lifestyle behaviours.

ABSTRACT

BACKGROUND: The target blood pressure (BP) value is unclear for diabetic kidney disease (DKD). Therefore, we aimed to evaluate the effect of strict BP control or 'on treatment' BP on clinical outcomes in patients with DKD. METHODS: A post-hoc analysis of the prespecified secondary outcomes of the FimAsartaN proTeinuriA SusTaIned reduCtion in comparison with losartan in diabetic chronic kidney disease (FANTASTIC) trial, a randomized multicenter double-blind phase III trial. Eligible patients were aged ≥ 19 years with DKD. We assigned 341 participants with DKD to BP control strategy (standard-systolic BP [SBP] < 140 mmHg versus strict-SBP < 130 mmHg). The outcome was the occurrence of cardiovascular events and renal events. Separate analyses were performed to compared the risk of outcome according to achieved average BP levels. RESULTS: A total of 341 participants were included in the analysis. Over a median follow-up of 2.8 years, cardiovascular/renal events were observed in 25 (7.3%) participants. Mean (SD) SBPs in the standard and strict BP control group were 140.2 (11.6) and 140.2 (11.9) mmHg, respectively. The strict BP control group did not show significantly reduced risk of cardiovascular/renal events (HR 1.32; 95% CI 0.60-2.92]). In the post-hoc analyses using achieved BP, achieved average SBP of 130-139 mmHg resulted in reduced risk of cardiovascular/renal events (HR 0.15; 95% CI 0.03-0.67) compared to achieved average SBP ≥ 140 mmHg, whereas further reduction in achieved average SBP < 130 mmHg did not impart additional benefits. CONCLUSION: In patients with DKD, targeting a SBP of less than 130 mmHg, as compared with less than 140 mmHg, did not reduce the rate of a composite of cardiovascular and renal events. Achieved SBP of 130-139 mmHg was associated with a decreased risk for the primary outcome in patients with DKD.

ABSTRACT

Purpose: This study aimed to develop a predictive model for monitoring chronological weight loss during the early postoperative period following bariatric surgery in Korean patients with morbid obesity. Materials and Methods: The baseline characteristics and postoperative weight loss outcomes were collected for up to 24 months after surgery in patients who underwent sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB). The factors influencing weight loss outcomes were analyzed, and longitudinal percentile charts were plotted using quantile regression models adjusted for the identified independent factors. Results: The analysis included 491 and 274 patients who underwent SG and RYGB, respectively, of whom 225 (29.4%) were men. A positive association was found between the maximum percentage of total weight loss (%TWL) and female sex, body mass index (BMI) ≥40, and age <40 years. Among patients who reached nadir BMI or had at least 12 months of follow-up data (n=304), 7.6% exhibited inadequate weight loss (TWL <20%). The predictors of insufficient weight loss were older age (>40 years), male sex, and psychological problems. Centile charts were generated for the entire cohort, incorporating age, sex, and the type of procedure as covariates. Conclusion: The percentile charts proposed in the present study can assist surgeons and healthcare providers in gauging patients' progress toward their weight loss goals and determining the timing of adjunctive intervention in poor responders during early postoperative follow-up.

ABSTRACT

BACKGROUND AND OBJECTIVES: Early diastolic mitral annular tissue (e') velocity is a commonly used marker of left ventricular (LV) diastolic function. This study aimed to investigate the prognostic implications of e' velocity in patients with mitral regurgitation (MR). METHODS: This retrospective cohort study included 1,536 consecutive patients aged <65 years with moderate or severe chronic primary MR diagnosed between 2009 and 2018. The primary and secondary outcomes were all-cause and cardiovascular mortality, respectively. According to the current guidelines, the cut-off value of e' velocity was defined as 7 cm/s. RESULTS: A total of 404 individuals were enrolled (median age, 51.0 years; 64.1% male; 47.8% severe MR). During a median 6.0-year follow-up, there were 40 all-cause mortality and 16 cardiovascular deaths. Multivariate analysis revealed a significant association between e' velocity and all-cause death (adjusted hazard ratio [aHR], 0.770; 95% confidence interval [CI], 0.634-0.935; p=0.008) and cardiovascular death (aHR, 0.690; 95% CI, 0.477-0.998; p=0.049). Abnormal e' velocity (≤7 cm/s) independently predicted all-cause death (aHR, 2.467; 95% CI, 1.170-5.200; p=0.018) and cardiovascular death (aHR, 5.021; 95% CI, 1.189-21.211; p=0.028), regardless of symptoms, LV dimension and ejection fraction. Subgroup analysis according to sex, MR severity, mitral valve replacement/repair, and symptoms, showed no significant interactions. Including e' velocity in the 10-year risk score improved reclassification for mortality (net reclassification improvement [NRI], 0.154; 95% CI, 0.308-0.910; p<0.001) and cardiovascular death (NRI, 1.018; 95% CI, 0.680-1.356; p<0.001). CONCLUSIONS: In patients aged <65 years with primary MR, e' velocity served as an independent predictor of all-cause and cardiovascular deaths.

ABSTRACT

Background: Current risk stratification strategies for patients with hypertrophic cardiomyopathy (HCM) are limited to traditional methodologies. Objectives: The authors aimed to establish machine learning (ML)-based models to discriminate major cardiovascular events in patients with HCM. Methods: We enrolled consecutive HCM patients from 2 tertiary referral centers and used 25 clinical and echocardiographic features to discriminate major adverse cardiovascular events (MACE), including all-cause death, admission for heart failure (HF-adm), and stroke. The best model was selected for each outcome using the area under the receiver operating characteristic curve (AUROC) with 20-fold cross-validation. After testing in the external validation cohort, the relative importance of features in discriminating each outcome was determined using the SHapley Additive exPlanations (SHAP) method. Results: In total, 2,111 patients with HCM (age 61.4 ± 13.6 years; 67.6% men) were analyzed. During the median 4.0 years of follow-up, MACE occurred in 341 patients (16.2%). Among the 4 ML models, the logistic regression model achieved the best AUROC of 0.800 (95% CI: 0.760-0.841) for MACE, 0.789 (95% CI: 0.736-0.841) for all-cause death, 0.798 (95% CI: 0.736-0.860) for HF-adm, and 0.807 (95% CI: 0.754-0.859) for stroke. The discriminant ability of the logistic regression model remained excellent when applied to the external validation cohort for MACE (AUROC = 0.768), all-cause death (AUROC = 0.750), and HF-adm (AUROC = 0.806). The SHAP analysis identified left atrial diameter and hypertension as important variables for all outcomes of interest. Conclusions: The proposed ML models incorporating various phenotypes from patients with HCM accurately discriminated adverse cardiovascular events and provided variables with high importance for each outcome.

To investigate the impact on the ovarian reserve after minimally invasive ovarian cystectomy using two platforms, the Da Vinci robotic system (Xi and SP) and the laparoscopic system. Patients underwent laparoscopic or Da Vinci robotic (Xi or SP) ovarian cystectomy for benign ovarian cysts between January 1, 2018, and December 31, 2022 at Guro Hospital, Korea University Medical center. We measured the change of AMH values (%) = [(postAMH - preAMH)] × 100/preAMH. No significant differences in preoperative age, cyst size, estimated blood loss during surgery, hemoglobin drop, length of hospital stay, adhesion detachment rate and cyst rupture rate were observed. However, the operative time was significantly shorter in the laparoscopic group than that in the robotic group (67.78 ± 30.58 min vs. 105.17 ± 38.87 min, p < 0.001) The mean preAMH and postAMH were significantly higher with the Da Vinci robotic group than with the laparoscopic group (preAMH: 5.89 ± 4.81 ng/mL vs. 4.01 ± 3.59 ng/mL, p = 0.02, postAMH: 4.36 ± 3.31 ng/mL vs. 3.08 ± 2.60 ng/mL, p = 0.02). However, the mean ΔAMH was not significantly different between two groups. ΔAMH also did not demonstrate significant differences among the three groups; laparoscopic, Xi and SP robotic. Even in the patient groups with preAMH < 2 and diagnosed with endometriosis, the ΔAMH did not show significant differences between the laparoscopic and robotic groups. The Da Vinci robotic system is no inferior to conventional laparoscopic systems in preserving ovarian function.

ABSTRACT

BACKGROUND: Primary focal segmental glomerulosclerosis (FSGS) is a glomerular disease that sometimes recurs in patients after kidney transplantation (KT) and increases the risk of graft loss. Proteinuria is a common early sign of recurrent FSGS, but an abrupt decrease in urine volume is rare. Herein, we report a patient with early recurrence of FSGS with anuria following KT. CASE PRESENTATION: A 55-year-old man with end-stage kidney disease caused by primary FSGS experienced anuria on postoperative day 2 following deceased donor KT. Laboratory results revealed that serum tacrolimus trough levels were consistently elevated at the time of anuria. At first, we considered acute calcineurin inhibitor (CNI) nephrotoxicity based on graft biopsy on light microscopy, laboratory findings, and clinical courses. However, the allograft function did not recover even after discontinuation of CNI, and recurrent FSGS was diagnosed 2 weeks later on electron microscopy. A total of 13 sessions of plasmapheresis and two administrations of rituximab (375 mg/m2) were required to treat recurrent FSGS. The patient achieved a partial response, and the spot urine protein-to-creatinine ratio decreased from 15.5 g/g creatinine to 5.2 g/g creatinine. At 5 months following KT, the serum creatinine level was stable at 1.15 mg/dL. CONCLUSIONS: These findings highlight that anuria can occur in cases of early recurrence of FSGS combined with acute CNI nephrotoxicity.

ABSTRACT

BACKGROUND/AIMS: Since the coronavirus disease 2019 (COVID-19) outbreak, hospitals have implemented infection control measures to minimize the spread of the virus within facilities. This study aimed to investigate the impact of COVID-19 on the incidence of healthcare-associated infections (HCAIs) and common respiratory virus (cRV) infections in hematology units. METHODS: This retrospective study included all patients hospitalized in Catholic Hematology Hospital between 2019 and 2020. Patients infected with vancomycin-resistant Enterococci (VRE), carbapenemase-producing Enterobacterales (CPE), Clostridium difficile infection (CDI), and cRV were analyzed. The incidence rate ratio (IRR) methods and interrupted time series analyses were performed to compare the incidence rates before and after the pandemic. RESULTS: The incidence rates of CPE and VRE did not differ between the two periods. However, the incidence of CDI increased significantly (IRR: 1.41 [p = 0.002]) after the COVID-19 pandemic. The incidence of cRV infection decreased by 76% after the COVID-19 outbreak (IRR: 0.240 [p < 0.001]). The incidence of adenovirus, parainfluenza virus, and rhinovirus infection significantly decreased in the COVID-19 period (IRRs: 0.087 [p = 0.003], 0.031 [p < 0.001], and 0.149 [p < 0.001], respectively). CONCLUSION: The implementation of COVID-19 infection control measures reduced the incidence of cRV infection. However, CDI increased significantly and incidence rates of CPE and VRE remained unchanged in hematological patients after the pandemic. Infection control measures suitable for each type of HCAI, such as stringent hand washing for CDI and enough isolation capacities, should be implemented and maintained in future pandemics, especially in immunocompromised patients.

ABSTRACT

BACKGROUND: Polycystic ovarian syndrome (PCOS) can be diagnosed when the anti-Müllerian hormone (AMH) levels are high, but in clinic, women who do not meet the diagnosis of PCOS but have elevated AMH levels are often seen. This study aimed to compare the differences in menstrual cycle patterns and hormone levels in women with regular menstrual cycles, but not PCOS, by dividing them into high and low AMH groups. MATERIAL AND METHODS: This multicenter prospective study included 68 healthy women. Participants with regular menstrual cycles were divided into two groups according to their AMH levels. The main outcome measures were menstrual cycle pattern, body mass index, and hormone levels (thyroid stimulating hormone, prolactin, testosterone, sex hormone-binding globulin, and free androgen index), which were compared between the groups according to AMH levels. The ovulation was assessed by performing pelvic ultrasound, and by assessing the hormone levels of the luteinizing hormone and progesterone. RESULTS: The criteria for determining normal and high AMH levels were based on previous literatures. The participants were divided into normal (39 people) and high (29 people) AMH group. No differences were found in age or BMI between the two groups, and no other differences were observed in TSH, prolactin, testosterone, or free androgen index. However, the high AMH group had significantly higher SHBG levels than the normal group (normal group: 65.46 ± 25.78 nmol/L; high group: 87.08 ± 45.05 nmol/L) (p = 0.025). CONCLUSIONS: This study is the first to analyze the association between SHBG and AMH levels in women with regular menstrual cycles. Elevated AMH levels are associated with increased levels of SHBG levels.
