Safety and Efficacy of Intravesical Epinephrine Instillation in Patients with Intractable Lower Urinary Tract Hematuria - A Novel Approach.

OBJECTIVE: To treat intractable hematuria with intravesical instillation of epinephrine. METHODS: Sixty patients were treated with intravesical instillation of epinephrine at Mackay Memorial Hospital. The control group was composed of 60 patients who were treated with standard-of-care cystoscopic electrocautery fulguration. Under general anesthesia, epinephrine-treated group were injected with 150 mL of diluted epinephrine (1:10,000) through cystoscopy, followed by bladder irrigation with 1:100,000-diluted epinephrine at the ward. Successful hemostasis was defined as hematuria resolution within 1 month post-treatment without additional invasive procedures. RESULTS: In the 60 patients who underwent intravesical instillation of epinephrine, radiation cystitis was the most common etiology (65.0%). Fifty-two patients (86.7%) required no additional therapy within 1 month after one course of intravesical epinephrine instillation treatment compared with 28 patients (46.7%) in the electrocautery fulguration-control group (P <.001). We observed a significant decrease in both the median length of hospitalization (P = .049) and the need for additional invasive procedures (P <.001) in the epinephrine group. In addition, cardiopulmonary monitoring of mean blood pressure, mean heart rate, and mean respiratory rate demonstrated no significant differences after epinephrine treatment. CONCLUSION: In this study, intravesical instillation of epinephrine was an innovative method of hemostasis for intractable lower urinary tract hematuria with a success rate of 86.7%, compared to 46.7% in the control group, and significantly reduced the number of additional procedures required and the length of hospitalization. It was well-tolerated by all patients, and was a safe and effective treatment modality for intractable hematuria or bladder hemorrhage.

Comparison of perinephric fat measurements between malignant and benign renal tumours.

OBJECTIVE: To investigate different parameters derived from the quantity and quality of perinephric fat, and to compare their effectiveness in predicting the malignant pathology of renal tumours. METHODS: Data from patients diagnosed with renal tumour between April 2014 and December 2020 were retrospectively reviewed, and patients were categorized into malignant or benign tumour groups. Fat parameters, including perinephric fat volume (PFV), perinephric fat area (PFA), perinephric fat thickness (PFT), and Mayo adhesive probability (MAP) score were measured using abdominal computed tomography scans. Between-group differences were assessed by analysis of variance and χ2-test. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the performance of perinephric fat parameters in diagnosing malignancy. RESULTS: A total of 109 patients were included. MAP score, PFV, PFA, and PFT were significantly increased in the malignant versus benign tumour group, and after correction for body mass index (BMI), the indexed PFV/BMI, PFA/BMI, and PFT/BMI values remained significantly higher in the malignant tumour group. All parameters showed fair predictivity of malignancy, with comparable area under the curve values in the ROC curve. CONCLUSION: An increased amount of perinephric fat is predictive of malignant pathology for renal tumours. The predictive accuracy for each perinephric fat parameter remained fair after correcting for BMI.

Comparison of Fragmentation and Dusting Modality Using Holmium YAG Laser during Ureteroscopy for the Treatment of Ureteral Stone: A Single-Center's Experience.

Laser ureteroscopic lithotripsy (URSL) is an efficacious treatment for ureteral stones. There have been few previous studies comparing the different energy and frequency settings for URSL in a single center. We compared these two laser modalities, which were simultaneously used in our medical center for the treatment of ureteral stones. Patients who underwent fragmentation or dusting laser URSL between September 2018 and June 2020 were retrospectively reviewed. We compared patients who underwent fragmentation and dusting laser and assessed the enhancing factors for stone free rate. There were a total of 421 patients with ureteral stones who met the study criteria. There was no significant difference between the characteristics of both groups. The fragmentation group had a better stone free rate and a lower retropulsion rate compared with the dusting group. Multivariate analysis revealed that stone basket use, no upper ureteral stone or pyuria significantly improved the stone free rate. Both laser modes were effective and safe for ureteral lithotripsy although the fragmentation system showed slightly higher effectiveness and lower complication rate.

Association of depression and antidepressant therapy with antiretroviral therapy adherence and health-related quality of life in men who have sex with men.

UNAIDS' HIV treatment targets require that 90% of people living with HIV/AIDS (PLWHA) receiving antiretroviral treatment (ART) achieve viral suppression and 90% of people with viral suppression have good health-related quality of life (HRQOL). This study aimed to examine the association of depression and antidepressant therapy with ART adherence and HRQOL in HIV-infected men who have sex with men (MSM). From 2018 through 2020, HIV-infected MSMs were consecutively recruited (N = 565) for the evaluation of ART adherence and HRQOL at Taipei City Hospital HIV clinics. Non-adherence to ART was defined as a Medication Adherence Report Scale score of < 23. HRQOL in PLWHHA was evaluated using WHOQOL-BREF, Taiwan version. Overall, 14.0% had depression and 12.4% exhibited non-adherence to ART. The nonadherence proportion was 21.8% and 10.5% in depressed and nondepressed HIV-infected MSM, respectively. After adjusting for other covariates, depression was associated with a higher risk of nonadherence to ART (adjusted odds ratio = 2.02; 95% confidence interval: 1.02-4.00). Physical, psychological, social, and environmental HRQOL were significantly negatively associated with depression. Considering antidepressant therapy, ART nonadherence was significantly associated with depression without antidepressant therapy but not with antidepressant therapy. The depressed HIV-infected MSM without antidepressant therapy had worse psychological, social, and environmental HRQOL than those with antidepressant therapy. Our study suggests that depression is associated with poor ART adherence and HRQOL, particularly in those without antidepressant therapy. Adequate diagnosis and treatment of depression should be provided for PLWHA to improve their ART adherence and HRQOL.

Retrieval of intrarenal coiled and ruptured guidewire by retrograde intrarenal surgery: A case report and literature review.

BACKGROUND: Foreign bodies in the kidney have rarely been reported. However, they can be a clinical problem for urologists. We report on a patient with a residual segment of guidewire coating embedded in the renal parenchyma following computed tomography (CT)-guided percutaneous nephrostomy drainage (PCND), and our successful minimally invasive management with retrograde intrarenal surgery (RIRS). CASE PRESENTATION: A 40-year-old female with urosepsis due to a right upper ureteral stone with hydronephrosis received emergent CT-guided PCND and subsequent ureteroscopic lithotripsy, double J stent insertion, and percutaneous catheter removal. Follow-up radiography showed a coiled object within the upper pole parenchyma of the right kidney, which might be the remnant of a guidewire used during the PCND procedure. Flexible ureteroscopy (fURS) was performed. Under fluoroscopy, the foreign body was localized, the renal parenchyma was incised with laser, and the foreign body was retrieved using a stone basket. CONCLUSION: Although guidewire breakage is uncommon, clinicians should keep it in mind during interventional procedures. Several methods can be used to eradicate foreign objects from the urinary tract, and the first choice should always be the least invasive one. RIRS with fURS is considered as a safe, efficient, and minimally invasive option for the extraction of foreign bodies from the kidney. To the best of our knowledge, this is the first comprehensive case report detailing the removal of a foreign object by RIRS in the English literature.

Clinical factors predicting ureteral stent failure in patients with external ureteral compression.

Double-J stent (DJ) placement is usually the treatment of choice for relieving external compression of the ureter. However, in some cases DJ function may become impaired and a percutaneous nephrostomy (PCN) may be required. Previous studies have reported different predictive factors for choosing PCN or DJ insertion as the initial treatment. In this study, we analyzed the risk factors for DJ failure in patients with external ureteral compression. Our results showed that the patients with moderate and severe hydronephrosis (p-value = 0.0171 and 0.0249, respectively), preexisting pyuria (p-value = 0.0128), or lower ureter obstruction (p-value = 0.0305) were more prone to DJ laterality. Age was also an important predictor. Urologists should pay more attention to these patients and consider PCN as the initial treatment.

Intrathoracic ureteric stent migration through a reno-pleural fistula: a case report of rare antegrade ureteric stenting complication.

BACKGROUND: Malignant obstruction and associated hydronephrosis is a common complication of advanced cervical cancer. Percutaneous nephrostomy (PCN) followed by antegrade stenting is often required to relieve obstruction as retrograde access fails in considerable proportion of such patients. Reno-pleural fistula is a rare complication of PCN which creates a patent connection between the renal collecting system and the thoracic cavity, and urine accumulation in the pleural space can cause pleural effusion (i.e., urinothorax). Upward or downward migration is a complication of indwelling ureteric stents. Further migration with extrusion outside of the urinary tract is uncommon. Herein we present an unprecedented case in adult of ureteric stent upward migration through a reno-pleural fistula into the thoracic cavity managed by thoracoscopy. CASE PRESENTATION: A 66-year-old female was diagnosed of advanced stage cervical cancer with suspicious bladder invasion. Given her bilateral hydronephrosis with impaired renal function, she underwent bilateral PCN and subsequent antegrade ureteric stenting. However, she presented with dyspnea, right back pain, and oliguria four days after bilateral PCN catheter removal. Computed tomography reported massive right pleural effusion and an intrathoracic ureteric stent within reno-pleural fistula. Thoracoscopy with thoracostomy was performed to remove the ureteric stent and urine in right pleural space. A week later, urinothorax had resolved and right PCN was performed again. She was discharged after regaining normal renal function with right PCN and a left ureteric stent in place. CONCLUSIONS: A reno-pleural fistula can serve as a route for ureteric stent migration and that continuous drainage of urine can cause urinothorax once the stent reaches the thoracic cavity. Anytime a supracostal approach is used for PCN, even when using small caliber catheters, clinicians should pay special attention given the risk of pleural injury and subsequent complications.

Rare paratesticular aggressive angiomyxoma mimicking an epididymal tumor in an 82-year-old man: Case report.

Aggressive angiomyxoma (AAM) is a rare mesenchymal myxoid tumor, and most cases occur in the pelvic region or perineum of adult females. AAM is very rare in males. Most of these cases have been diagnosed in patients aged 30-60 years, and the tumors involved the pelvic cavity, scrotum, or spermatic cord. AAM can mimic inguinal hernia, hydrocele, or paratesticular neoplasm. Four male cases have been reported with paratesticular AAM mimicking a testicular/epididymal tumor, and to the best of our knowledge, this is the oldest patient in the literature. Because of its rarity, making an exact diagnosis before surgery is difficult. Herein, we present a case of AAM in an 82-year-old man and review the literature.

Discovery of an Orally Efficacious MYC Inhibitor for Liver Cancer Using a GNMT-Based High-Throughput Screening System and Structure-Activity Relationship Analysis.

Glycine-N-methyl transferase (GNMT) downregulation results in spontaneous hepatocellular carcinoma (HCC). Overexpression of GNMT inhibits the proliferation of liver cancer cell lines and prevents carcinogen-induced HCC, suggesting that GNMT induction is a potential approach for anti-HCC therapy. Herein, we used Huh7 GNMT promoter-driven screening to identify a GNMT inducer. Compound K78 was identified and validated for its induction of GNMT and inhibition of Huh7 cell growth. Subsequently, we employed structure-activity relationship analysis and found a potent GNMT inducer, K117. K117 inhibited Huh7 cell growth in vitro and xenograft in vivo. Oral administration of a dosage of K117 at 10 mpk (milligrams per kilogram) can inhibit Huh7 xenograft in a manner equivalent to the effect of sorafenib at a dosage of 25 mpk. A mechanistic study revealed that K117 is an MYC inhibitor. Ectopic expression of MYC using CMV promoter blocked K117-mediated MYC inhibition and GNMT induction. Overall, K117 is a potential lead compound for HCC- and MYC-dependent cancers.

Preoperative estimate of natural ureteral length based on computed tomography and/or plain radiography.

To predict natural ureter lengths based on clinical images. We reviewed our image database of patients who underwent multiphasic computed tomography urography from January 2019 to April 2020. Natural ureteral length (ULCTU) was measured using a three-dimensional curved multiplanar reformation technique. Patient parameters including age, height, and height of the lumbar spine, the index of ureteral length using kidney/ureter/bladder (KUB) radiographs (C-P and C-PS) and computed tomography (ULCT) were collected. ULCTU correlated most strongly with ULCT. R square and adjusted R square values from multivariate regression were 0.686 and 0.678 (left side) and 0.516 and 0.503 (right side), respectively. ULCTU could be estimated by the regression model in three different scenarios as follows: ULCT + C-P ULCTUL = 0.405 [Formula: see text] ULCTL [Formula: see text] 0.626 [Formula: see text] C-PL - 0.508 cm ULCTUR = 0.558 [Formula: see text] ULCTR [Formula: see text] 0.218 [Formula: see text] C-PR + 6.533 cm ULCT ULCTUL = 0.876 [Formula: see text] ULCTL [Formula: see text] 6.337 cm ULCTUR = 0.710 [Formula: see text] ULCTR [Formula: see text] 9.625 cm C-P ULCTUL = 0.678 [Formula: see text] C-PL [Formula: see text] 4.836 cm ULCTUR = 0.495 [Formula: see text] C-PR [Formula: see text] 10.353 cm We provide equations to predict ULCTU based on CT, KUB or CT plus KUB for different clinical scenarios. The formula based on CT plus KUB provided the most accurate estimation, while the others had lower validation values but could still meet clinical needs.

Analysis of risk factors of bladder neck contracture following transurethral surgery of prostate.

BACKGROUNDS: The aim of the present study was to investigate the perioperative parameters associated with bladder neck contracture (BNC) after transurethral surgery of the prostate and to compare the incidence of BNC after transurethral resection of the prostate (TURP) or Thulium vaporesection (resection group) versus Thulium vapoenucleation or enucleation of the prostate (enucleation group). METHODS: Between March 2008 and March 2020, 2363 patients received TURP and 1656 patients received transurethral surgery of the prostate with Thulium laser (ThuP) at Mackay Memorial Hospital. A total of 62 patients developed BNC. These BNC patients were age-and operation-matched to 124 randomly sampled TURP/ThuP controls without BNC. A 1:1 propensity score matching model was used to evaluate the difference in incidence of BNC. RESULTS: Our study demonstrated that a greater proportion of BNC patients had history of cerebrovascular accidents (11/62 vs. 7/124, p = 0.009), coronary artery disease (14/48 vs. 16/108, p = 0.03), chronic kidney disease (14/62 vs. 11/124, p = 0.01), and two or more comorbidities (29/62 vs. 27/124, p = 0.001) compared with NBNC patients. Multivariate analysis showed that smaller prostate volume (OR 0.96 (0.94-0.99), p = 0.008) and recatherization (OR 5.6 (1.02-30.6), p = 0.047) were significantly associated with BNC. A ROC curve predicted that a prostate volume < 42.9 cm3 was associated with a notably higher rate of BNC. The propensity score matching model reported there was no difference in incidence between resection and enucleation groups. CONCLUSION: This study demonstrated that incidence of BNC was the same in different surgical techniques and that low prostate volume, recatherization and ≥ 2 comorbidities were positively correlated with the development of BNC after TURP or ThuP.

Source identification of HIV-1 transmission in three lawsuits Using Ultra-Deep pyrosequencing and phylogenetic analysis.

BACKGROUND/PURPOSE: Intentional transmission of HIV-1 is a crime. Identifying the source of transmission between HIV-1 infected cases using phylogenetic analysis has limitations, including delayed examinations after the initiation of infection and ambiguity of phyletic relationships. This study was the first to introduce phylogenetic tree Results as forensic evidence in a trial in Taiwan. METHODS: Three lawsuit cases from different district courts in Taiwan were chosen for this study. We identified the source of transmission between individuals in each lawsuit based on the maximum likelihood and Bayesian phylogenetic tree analyses using the HIV-1 sequences from molecular cloning and ultra-deep pyrosequencing (UDPS). Two gene regions of the HIV genome, env and gag, were involved. RESULTS: The results of phylogenetic analysis using sequences from molecular cloning were clear and evidential enough in lawsuits 1 and 3. Due to the delayed sampling time, the result of sequences from molecular cloning in lawsuit 2 was ambiguous. Combined with the analyzed result of sequences from UDPS and epidemiological information, the source of transmission in lawsuit 2 was further identified. CONCLUSION: Hence phylogenetic analyses cannot exclude the possibility of unsampled intermediaries, the data interpretation should be more careful and conservative, and it should not be considered as the only evidence for the source identification in a trial without epidemiological or serological information. The evaluation of the introduced UDPS method in the identification of transmission source has shown that the validity and evidential effects were still limited and need further optimization.

Comparison of ultrasound-assisted and pure fluoroscopy-guided extracorporeal shockwave lithotripsy for renal stones.

BACKGROUND: In this study, we aimed to compare the efficacy and clinical outcomes of shock wave lithotripsy (SWL) for patients with renal stones using pure fluoroscopy (FS) or ultrasound-assisted (USa) localization with two lithotripters. METHODS: We retrospectively identified 425 patients with renal calculi who underwent SWL with either a LiteMed LM-9200 ELMA lithotripter (209 cases), which combined ultrasound and fluoroscopic stone targeting or a Medispec EM-1000 lithotripter machine (216 cases), which used fluoroscopy for stone localization and tracking. The patient demographic data, stone-free rates, stone disintegration rates, retreatment rates and complication rates were analyzed. RESULTS: The USa group had a significantly higher overall stone-free rate (43.6 vs. 28.2%, p < 0.001) and stone disintegration rate (85.6 vs. 64.3%, p < 0.001), as well as a significantly lower retreatment rate (14.8 vs. 35.6%, p < 0.001) and complication rate (1.9 vs. 5.5%, p = 0.031) compared with the FS group. This superiority remained significant in the stone size < 1 cm stratified group. In the stone size > 1 cm group, the stone-free rate (32.4 vs. 17.8%, p = 0.028), disintegration rate (89.2 vs. 54.8%, p = 0.031) and retreatment rate (21.6 vs. 53.4%, p < 0.001) were still significantly better in the USa group, however there was no significant difference in the complication rate. The most common complication was post-SWL-related flank pain. CONCLUSION: SWL is a safe and non-invasive way of treating renal stones. This study compared two electromagnetic shock wave machines with different stone tracking systems. LiteMed LM-9200 ELMA lithotripter, which combined ultrasound and fluoroscopic stone targeting outperformed Medispec EM-1000 lithotripter, which used fluoroscopy for stone localization and tracking, with better stone-free rates and disintegration rates, as well as lower retreatment rates and complications with possible reduced radiation exposure.

Zonal adjusted PSA density improves prostate cancer detection rates compared with PSA in Taiwanese males with PSA < 20 ng/ml.

BACKGROUND: The current study aimed to compare the efficacy of transition zone PSA density (TZPSAD) with traditional PSA and PSA density (PSAD), for the diagnosis of prostate cancer (PCa) in Taiwanese males. METHODS: Men with PSA between 4.0 and 20.0 ng/ml who underwent a transrectal ultrasound (TRUS) guided prostate biopsy between the studied period were retrospectively identified. The demographic data, PSAD and TZPSAD were calculated in all patients. Receiver operating characteristic (ROC) curves were used to analyze the accuracy of a positive PCa diagnosis. RESULTS: The area under the ROC (AUC) was 0.615, 0.748 and 0.746 for PSA, PSAD and TZPSAD, respectively. The best cut-off of value for TZPSAD in predicting PCa in men with a PSA of 4.0-10.0 ng/ml was 0.367 ng/ml/ml with a sensitivity of 50% and a specificity of 77.5%. In men with a PSA of 10.1-20.0 ng/ml, the best cut-off value was 0.454 ng/ml, with a sensitivity of 74.8% and specificity of 70.9%. CONCLUSION: The use of TZPSAD can improve the efficiency and specificity of PSA for the diagnosis of PCa in Taiwanese men with PSA 4.0-20.0 ng/ml. TZPSAD efficiency was similar to PSAD but TZPSAD had better cancer specificity.

Methamphetamine Use Associated with Non-adherence to Antiretroviral Treatment in Men Who Have Sex with Men.

Methamphetamine is a prevalent recreational drug among men who have sex with men (MSM) living with HIV and could cause the cognitive impairment and memory loss. However, studies on the association between methamphetamine use and adherence to antiretroviral treatment (ART) are limited and had inconsistent findings. This study aimed to determine the impact of methamphetamine use on adherence to ART among MSM living with HIV. From December 2018 to October 2019, MSM living with HIV were recruited (N = 351) and non-adherence to ART was defined as a Medication Adherence Report Scale score of <23. Overall, 16.0% of the participants reported methamphetamine use in the prior three months and 13.4% of the participants had non-adherence to ART. The proportion of non-adherence to ART among HIV-positive MSM were 28.6% and 10.5% with and without methamphetamine use, respectively. After controlling for demographics, illicit drug use, and co-morbidities, methamphetamine use during the prior three months was associated with a higher risk of non-adherence to ART (adjusted odds ratio = 3.08; 95% confidence intervals: 1.24-7.69). Compared with HIV-positive MSM with non-adherence to ART, HIV-positive MSM with good adherence to ART had a higher CD4 counts and were more likely to achieve an undetectable viral load. Since poor adherence to ART is associated with an increased HIV viral load and the risk of HIV transmission to others, our study suggests that it is imperative to screen HIV-positive patients for methamphetamine use and to provide effective therapy to reduce methamphetamine use and the associated non-adherence to ART.

Concurrent müllerianosis of the urinary bladder and the umbilicus presenting with umbilical bleeding: a rare case report and review of the literature.

BACKGROUND: Müllerianosis is a very rare neoplasm composed of two or three Müllerian derived tissues (endosalpinx, endometrium and endocervix). We report the first case of concurrent müllerianosis of the urinary bladder and the umbilicus presenting with umbilical bleeding. CASE PRESENTATION: A 43-year-old Asian premesopausal female, gravida 1, para 1, presented with intermittent umbilical bleeding. An umbilical nodule and a bladder tumor on the posterior wall of the urinary bladder were identified. She underwent transurethral resection of the bladder tumor and excision of the umbilical nodule successively. Diagnosis of müllerianosis was confirmed by the histological and immunological features. No tumor recurrence was noted at 6 months of follow-up. CONCLUSIONS: Müllerianosis is extremely rare and mainly reported in the urinary bladder, and generally affects women of reproductive age. Despite the common presentations of müllerianosis of the urinary bladder including irritative voiding symptoms, abdominal/pelvic pain and gross hematuria, our rare case had no symptom except umbilical bleeding. The possibility of concurrent bladder müllerianosis should be considered when müllerianosis is found at other location. We suggest a surgical intervention to establish the correct pathological diagnosis because it is essential to exclude malignant neoplasms of the urinary bladder. The majority of patients have a favorable prognosis.

Utilizing Experimental Mouse Model to Identify Effectors of Hepatocellular Carcinoma Induced by HBx Antigen.

Hepatocellular carcinoma (HCC) is among the ten most commonly diagnosed cancers and the fourth leading cause of cancer-related death. Patients with hepatitis B virus (HBV) infection are prone to developing chronic liver diseases (i.e., fibrosis and cirrhosis), and the HBV X antigen plays an important role in the development of HCC. The difficulty in detecting HCC at the early stages is one of the main reasons that the death rate approximates the incidence rate. The regulators controlling the downstream liver protein expression from HBV infection are unclear. Mass spectrometric techniques and customized programs were used to identify differentially expressed proteins which may be involved in the development of liver fibrosis and HCC progression in hepatitis B virus X protein transgenic mice (HBx mice). FSTL1, CTSB, and TGF-ß enhanced the signaling pathway proteins during the pathogenesis of HBx. Missing proteins can be essential in cell growth, differentiation, apoptosis, migration, metastasis or angiogenesis. We found that LHX2, BMP-5 and GDF11 had complex interactions with other missing proteins and BMP-5 had both tumor suppressing and tumorigenic roles. BMP-5 may be involved in fibrosis and tumorigenic processes in the liver. These results provide us an understanding of the mechanism of HBx-induced disorders, and may serve as molecular targets for liver treatment.

The relationship between androgen deprivation therapy and depression symptoms in patients with prostate cancer.

AIM: In this study, we administered a questionnaire to consecutive prostate cancer patients who received androgen deprivation therapy (ADT) for understanding the prevalence of depression symptoms. MATERIALS AND METHODS: We retrospectively identified patients with prostate adenocarcinoma who received ADT between January 2015 and February 2018 at Mackay Memorial Hospital. The patients were then asked to complete the Chinese version of the Patient Health Questionnaire-9 (PHQ-9) during an interview. The patients were divided into two groups according to PHQ-9 score: those with depression symptoms (PHQ-9 ≥ 6, depression group), and those without depression symptoms (PHQ-9 < 6, non-depression group). Two groups were compared using t-tests and correlation coefficients, as appropriate. Statistical significance was set at p < .05. RESULTS: There were no significant correlations between PHQ-9 scores and any of the parameters in the patients overall. In subgroup analysis, a positive correlation was found between the duration of ADT and PHQ-9 score in the patients with depression symptoms (p = .03). In addition, univariate analysis showed a positive association between the duration of ADT and PHQ-9 score, and a longer duration of ADT was further independently associated with increased PHQ-9 score in multivariate analysis in the patients with depression symptoms. CONCLUSION: This study demonstrated that in patients with prostate cancer and depression symptoms, the severity of the depression symptoms was positively correlated with the duration of ADT. In contrast, this association was not found in patients without depression symptoms.

Sex Differences in the Association of Fat and Inflammation Among People with Treated HIV Infection.

INTRODUCTION: Ectopic fat deposition may contribute to chronic inflammation in people with HIV (PWH). To provide information for future mechanistic studies of metabolic risk in this population, we sought to determine which fat measures relate more strongly to inflammation and whether the fat-inflammation relationship is modified by sex or HIV status. METHODS: We conducted a cross-sectional study of 105 PWH and 20 age- and sex-matched HIV-negative controls. Interleukin-6 (IL-6) and high-sensitivity C reactive protein (hs-CRP) levels were measured from plasma. Pericardial fat (PCF) and thoracic periaortic adipose tissue (TAT) volumes and peri-right coronary artery (RCA), left atrium (LA) roof, and liver densities were measured from cardiac CT scans. Unadjusted and multivariate adjusted linear regression models were used to determine the relationship between ectopic fat measures and inflammation biomarkers. RESULTS: Forty participants had BMI < 25, 33 had BMI 25 to 30, and 52 had BMI > 30. Systolic blood pressure and insulin resistance increased with BMI. Participants with higher BMI had a higher CD4+ count. In models adjusted for demographics, HIV status, and metabolic risk factors, BMI was positively associated with IL-6 and hs-CRP. Ectopic PCF and TAT volumes were positively associated with IL-6 and hs-CRP; however, these relationships were somewhat attenuated in adjusted models. LA roof (but not peri-RCA) fat radiodensity was inversely associated with hs-CRP in fully adjusted models, and the association with IL-6 was borderline statistically signifi-cant (P = 0.054). IL-6 was more strongly associated with BMI and LA roof density in women than in men (P for interaction = 0.05). CONCLUSIONS: Among PWH receiving antiretroviral therapy, higher BMI and excessive ectopic fat burden were associated with circulating markers of systemic inflammation. Because these measures appear to be more strongly related to inflammation among women than men, future clinical studies of metabolic risk and inflammation among PWH should include sex-stratified analyses.
