A treatment algorithm for healthy young men with erectile dysfunction.

OBJECTIVES: To assess baseline characteristics of a cohort of young men with erectile dysfunction (ED) but no identifiable organic cause and to evaluate the efficacy of our treatment algorithm. PATIENTS AND METHODS: We retrospectively reviewed the charts of men aged <40 years referred to our tertiary care centre for evaluation and treatment of their ED between March 2010 and August 2016. Of 185 men reviewed, we included 73 men who were identified as having no identifiable organic cause for their ED and had successfully completed a detailed questionnaire regarding their medical and sexual history at the initial consultation. The questionnaire was used to obtain baseline patient characteristics and identify comorbid conditions which may predispose to ED. For these men, our standard treatment comprised a daily low-dose phosphodiesterase type 5-inhibitor along with a referral for psychosexual therapy, with the option of more invasive treatment if this initial approach failed. After a minimum of 6 months of treatment, patients were asked to complete a follow-up questionnaire via phone or e-mail. Thirty-three men successfully completed the follow-up questionnaire. Pre- and post-treatment questionnaires were compared to determine treatment adherence and efficacy. RESULTS: The mean (range) age of the study cohort was 31.9 (22-39) years. At the initial consultation, 85% of men (n = 62) reported problems obtaining an erection. After a minimum of 6 months of treatment, only 42% reported the same problem (n = 14), with 58% (n = 19) satisfied with their erectile function. Post-treatment International Index of Erectile Function (IIEF) scores showed a significant improvement in erectile function (18.8 vs 13.3; P < 0.01), orgasmic function (7.7 vs 6.2; P = 0.01) and overall satisfaction (6.1 vs 4.5; P < 0.01). No statistically significant improvement was noted in sexual desire or intercourse satisfaction. CONCLUSIONS: Our proposed treatment approach for men with ED aged < 40 years without an identifiable organic aetiology appears to be a reasonable and effective first-line approach, as demonstrated by significantly improved post-treatment IIEF scores and patient-reported outcomes. This algorithm can provide urologists with a useful framework for managing these potentially challenging patients.

The Surgical Treatment of Peyronie's Disease in the Older Man: Patient Characteristics and Surgical Outcomes in Men 65 and Older.

INTRODUCTION: Surgery remains the gold standard for the correction of penile deformities secondary to Peyronie's disease (PD). Nevertheless, there is no published data on the surgical treatment of PD in older men. AIM: Considering the aging national and international population, we sought to evaluate the pre-operative characteristics and surgical outcomes of men aged 65 or older who underwent surgical treatment for PD at our tertiary care institution. METHODS: We retrospectively reviewed the charts of all men 65 years or older who underwent surgery for PD from January 2010 to September 2017. We compared men who underwent penile prosthesis implantation with straightening maneuvers (PP+SMs), tunica albuginea plication (TAP), and plaque partial excision with grafting (PEG). MAIN OUTCOME MEASURE: The main objective of this study was to find the baseline pre-operative patient characteristics and postoperative patient-reported outcomes. RESULTS: A total of 86 men with a median age of 68 years underwent surgery during the study period. 39 men underwent PP+SM (45%), 25 men a TAP (29%), and 22 men a PEG (26%). The mean curvature for all men was 59.9 ± 22.0° (range 0-105°). Those who underwent a PEG had a mean ± SD degree of curvature of 78.6 ± 16.6°, significantly higher than those who underwent PP+SM or TAP (49.1 ± 20.2° and 61.4 ± 17.4°, respectively; P < .001). Moreover, men who underwent a PEG had significantly more complex penile deformities (eg, narrowing with hinge effect) and better reported baseline erectile function compared with men who underwent PP+SM or TAP. Overall, 95% of all men reported having a functionally straight penis postoperatively with 94% engaging in penetrative intercourse at last follow-up. Overall, patient-reported satisfaction was 85% with a median follow-up of 43.5 months. CLINICAL IMPLICATIONS: Our findings suggest that the surgical treatment of PD in older men is safe, effective, and associated with high patient satisfaction. Although this represents a surgical series susceptible to selection bias, it underscores the importance of patient selection and counseling in achieving good surgical outcomes. STRENGTHS & LIMITATIONS: Our study is the first to report on outcomes of surgical treatment of PD in an elderly patient population with relatively long-term follow-up. Our limitations include a small sample size, single operating surgeon, and the lack of a younger comparison group. CONCLUSION: Despite an aging global population, surgery remains a viable and reliable option for the properly selected and counseled older men with PD. Abdelsayed GA, Setia SA, Levine LA.

Ambicor 2-Piece Inflatable Penile Prosthesis: Who and How?

BACKGROUND: Currently the Ambicor is the only 2-piece inflatable penile prosthesis (IPP) available in the United States. By eliminating the separate reservoir, this provides certain advantages for patient and surgeon. Nevertheless, it composes a small percentage of all IPPs implanted in the United States. AIM: To detail the surgical technique for implantation, describe the ideal patient candidates best suited for the Ambicor, and discuss the most common and some rare complications with a review of the available published literature in combination with our clinical experience. METHODS: A PubMed literature search was performed to obtain all peer-reviewed articles published in English specifically on the Ambicor 2-piece IPP. We also reviewed our clinical experience with the Ambicor during the past 2 decades. RESULTS: The published data remain limited, because few articles on the Ambicor have been published in the past 10 years. Overall complication rates were 2.1% to 9.5%. Patient satisfaction rates were 75% to 96.4%, with similar partner satisfaction rates. Relative contraindications for implantation include patients with significant penile deformities, long narrow phalluses, or short phalluses. STRENGTHS AND LIMITATIONS: Despite the limited available published data with short follow-up periods, this review provides a comprehensive discussion on the technical aspects and relevant perioperative counseling recommended for Ambicor implantation. CONCLUSION: The prosthetic urologist should offer the Ambicor 2-piece IPP to patients with erectile dysfunction whose non-surgical treatment has failed. Certain implanters might want to avoid the blind retropubic reservoir placement that occurs with 3-piece IPPs and might not be comfortable with an ectopic approach and therefore prefer using a 2-piece device. We believe the ideal Ambicor candidate is a patient with a current or future pelvic organ transplant, decreased manual dexterity, in need of complete phallic reconstruction, or with known extensive prior abdominopelvic surgery.

Healthcare utilization in men with poorer sexual and urinary function recovery following robot-assisted radical prostatectomy.

PURPOSE: Robotic radical prostatectomy focuses on oncologic cure, urinary continence and sexual function recovery. However, little is known about the effect of declines in urinary continence and sexual function on healthcare utilization. We aim to identify these factors. MATERIALS AND METHODS: From March 2011 to September 2013, all men undergoing robotic prostatectomy within our healthcare system were enrolled. Men completed the expanded prostate cancer index composite-26 survey at the time of diagnosis and 90 days post-operatively. Patients were stratified according to change in scores in the sexual function and urinary incontinence domains. Patient, treatment and post-op utilization patterns were examined for association with the extent of decline in sexual function and urinary continence. Multivariate linear regression was used to identify factors independently associated with decline in continence and sexual function. RESULTS: A total of 411 men who completed the baseline survey and at 90 days postoperatively were included. On multivariate linear regression, younger age (p < 0.01), higher preoperative sexual function (< 0.01), single marital status (p = 0.04) and more post-surgery email contacts (p = 0.04) were associated with higher declines in sexual function. For continence, no family history of prostate cancer (p = 0.01), higher baseline continence (p < 0.01) and more post-surgery physical therapy visits (p < 0.01) were associated with higher declines. CONCLUSIONS: Patients with the poorest quality of life outcomes at 90 days post-operatively were more likely to seek care via email and physical therapy encounters related to sexual function and urinary incontinence, respectively. This suggests that maximizing post-treatment quality of life can potentially reduce healthcare utilization.

Congenital Riedel's lobe of the liver: A case report.

Riedel's lobe of the liver is a rare anatomical variant often incidentally found on imaging or through the presence of hepatomegaly on physical examination. While patients are usually asymptomatic, the presentation of this condition can vary, ranging from nonspecific symptoms to more severe issues such as torsion, obstruction, rupture, and bleeding. We present a case of a patient with asymptomatic hepatomegaly who was incidentally found to have Riedel's lobe of the liver, accompanied by an elevated IgG mitochondrial antibody. The range of symptoms associated with this rare anatomical variation underscores its importance in diagnosis and surveillance within this patient population.

Principal component analysis based pre-cystectomy model to predict pathological stage in patients with clinical organ-confined bladder cancer.

OBJECTIVE: To develop a model that integrates the clinical and pathological information prior to radical cystectomy to increase the accuracy of current clinical stage in prediction of pathological stage in patients with bladder cancer (BC) using a modelling approach called principal component analysis (PCA). PATIENTS AND METHODS: In a single-centre retrospective study, demographic and clinicopathological information of 1186 patients with clinically organ-confined (OC) BC was reviewed. Putative predictors of post-cystectomy pathological stage were identified using a stepwise logistic regression model. Patients were randomly divided into training data set (two-thirds of the study population, 790 patients) and test data set (one-third of the study population, 396 patients). The PCA method was used to develop the model in the training data set and the cut-off point (PCA score) to differentiate pathological OC disease from extravesical disease was determined. The model was then applied to the test data set without recalculation. RESULTS: In all, 685 patients (57.7%) had pathological OC disease. Age, clinical stage, number of intravesical treatments, lymphovascular invasion, multiplicity of tumours, hydronephrosis and palpable mass were incorporated into the PCA model as predictors of pathological stage. The sensitivity and specificity of the PCA model in the test data set were 62.8% (95% CI 55.6%-68.1%) and 68.9% (95% CI 60.8%-76.0%), respectively. The positive and negative predictive values were 75.8% (95% CI 69.0%-81.6%) and 51.5% (95% CI 44.4%-58.5%), respectively. CONCLUSIONS: The pre-cystectomy PCA model improved the ability to differentiate OC disease from extravesical BC and especially decreased the under-staging rate. The pre-cystectomy PCA model represented a user-friendly staging aid without the need for sophisticated statistical interpretation.

Early and late implications of COVID-19 on male reproductive health: 3 years of data.

INTRODUCTION: COVID-19 (coronavirus disease 2019), caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), has significantly affected global health. Research has shown that the virus can be found at high concentrations in male gonadal tissue. Yet, the virus's long-term implications on male reproductive health remains relatively unclear. OBJECTIVE: A comprehensive narrative review of published literature regarding COVID-19's short- and long-term implications on male reproductive health. METHODS: A literature search of the PubMed and EMBASE databases was performed for articles ranging from November 2019 to August 2022. Studies that focused on the impact of COVID-19 on male reproductive health were selected for review. Studies were included if they were written in English and reported semen analyses, pathologic gonadal tissue analyses, serum androgen assays, or a combination of these in patients with COVID-19. Moreover, literature was included on COVID-19 vaccinations' impacts on male reproductive health. Case reports and other narrative reviews were excluded from this review. RESULTS: SARS-CoV-2 has been detected in cadaveric testicular tissue during the initial stages of infection in fatal cases of the disease, demonstrating marked inflammatory changes and decreased spermatogenesis in patients with COVID-19. Several studies have revealed a negative impact on androgens during acute illness and in the ensuing months, but data on the recovery of androgen levels are confounding and limited in scope. COVID-19 does have significant negative impacts on bulk semen parameters, as confirmed in studies comparing pre- and post-COVID-19 semen samples. Vaccination is a valuable tool for protecting patients from the negative impacts of the virus and has been shown to have no negative impact on male reproductive potential. CONCLUSION: Given the virus's impacts on testicular tissue, androgens, and spermatogenesis, COVID-19 can negatively affect male reproductive health for an extended period. Therefore, vaccinations should continue to be recommended to all eligible patients.

Motility disorders of the upper gastrointestinal tract in the intensive care unit: pathophysiology and contemporary management.

Upper gastrointestinal (GI) dysmotility, an entity commonly found in the intensive care unit setting, can lead to insufficient nutrient intake while increasing the risk of infection and mortality. Further, overcoming the altered motility with early enteral feeding is associated with a reduced incidence of infectious complications in intensive care unit patients. Upper GI dysmotility in critical care patients is a common occurrence, and there are many causes for this problem, which affects a very heterogenous population with a multitude of underlying medical abnormalities. Therefore, it is of utmost importance to identify this widespread problem and subsequently institute a proper therapy as rapidly as possible. Prokinetic pharmacotherapies are currently the mainstay for the management of disordered upper GI motility. Future therapies, aimed at the underlying pathophysiology of this complex problem, are under investigation. These aim is to reduce the side effects of the currently available options, while improving on nutrition delivery in the critically ill. This review discusses the pathophysiology, clinical manifestations, diagnosis, and treatment of upper GI motility disturbances in the critically ill.

Rising Prevalence of Anxiety and Depression in Chronic Pancreatitis: A Nationwide Analysis.

OBJECTIVES: We aim to characterize the prevalence and impact of anxiety and depression (AD) in hospitalized patients with chronic pancreatitis (CP). Anxiety and depression have been shown to have a significant impact on mortality and length of stay in gastrointestinal diseases, but there are limited studies evaluating its impact on CP. METHODS: We performed a retrospective analysis using the National Inpatient Sample from 2007 to 2014. The outcomes were the prevalence and trend of AD, impact on mortality, length of stay, and cost and independent predictors of AD. RESULTS: A total of 75,744 patients with CP were included in our analysis, of which 23,323 (31%) had anxiety or depression. The prevalence of anxiety increased from 7.33% in 2007 to 20.02% in 2014. Depression increased from 18.49% in 2007 to 23.89% in 2014. Independent predictors of AD were decreasing age, female sex, and multiple comorbidities. Decreased risk was seen in African Americans, Hispanics, and those from the South and West. Anxiety and depression did not impact overall mortality or length of stay. CONCLUSIONS: Anxiety and depression are increasingly recognized diagnosis in patients with CP. Careful management and treatment of psychiatric illnesses and improving quality of life need to be addressed for these patients.

The Spontaneous Regression of Primary Gastrointestinal Malignancies: An Observational Review.

The spontaneous regression or remission (SR) of cancer, often described as the partial or complete disappearance of a malignant tumor in the absence of all medical treatment and therapy, is a well-documented phenomenon. With efforts ongoing to establish cancer treatments that limit undesirable outcomes and adverse effects, these uncommon occurrences of SR carry significant implications for novel therapies and warrant further investigation. While several case studies have reported instances of SR in gastrointestinal (GI) malignancies, a comprehensive review of previous manifestations of SR in the GI tract remains lacking. The inclusion criteria for the rare phenomenon are also in need of an appropriate update that takes recent scientific advancements and emerging new medical technologies into account. Our analysis of 390 cases of SR in the GI tract focuses primarily on neoplasms of the hepatobiliary system and proposes an updated version of the older inclusion criteria for spontaneous regression.

Peyronie's Disease: What About the Female Sexual Partner?

INTRODUCTION: Peyronie's disease (PD) is an acquired wound-healing disorder of the penis involving fibrosis and scar formation within the tunica albuginea that can lead to various penile deformities resulting in penile pain, sexual dysfunction, low self-esteem, and emotional distress. While many studies highlight the psychosocial impact of PD on the patient, little is known about the female partner's experience regarding PD and its management. OBJECTIVES: To evaluate and summarize the available clinical data on the effects of the disease and its management on female sexual partners of patients with PD. METHODS: A search of the available medical literature using the MEDLINE and PubMed databases was performed. The queried terms included the following: Peyronie's disease, partner, female, dyspareunia, relationship, satisfaction, survey, and outcome. Studies were included only if the female sexual partners were directly evaluated or interviewed. RESULTS: PD can have a significant impact on the sexual function and satisfaction of female sexual partners. Most female sexual partners reported an improvement in their relationship, a decrease in sexual dysfunction, and improved overall satisfaction after both surgical and nonsurgical treatment. CONCLUSION: PD can be emotionally debilitating for patients and their partners. It has been associated with depression, social stigmatization, isolation, diminished self-worth, and avoidance of intimacy. A partner's experience with PD, as well as its management and outcomes, is an understudied entity that warrants further investigation and may be useful in guiding future treatment approaches.

The impact of platelets on the progression of traumatic intracranial hemorrhage.

BACKGROUND: The purpose of this study was to analyze the association of the initial platelet count with mortality and progression of intracranial hemorrhage (ICH) in blunt traumatic brain injured (TBI) patients. METHODS: All blunt trauma patients with severe TBI admitted from January 2006 to December 2007 were retrospectively identified. Patients with a chest, abdomen, or extremity AIS score >3 were excluded to minimize the impact of concomitant injuries on the outcomes of the patients. All brain computed tomography scans were reviewed to analyze ICH progression. Discrete platelet cutoff values were entered into a multiple regression model to detect critical thresholds associated with ICH progression and mortality. RESULTS: Of 626 TBI patients, 310 (49.5%) had a minimum of two brain computed tomography scans and were able to have ICH progression evaluated. Patients with platelets <175,000/mm3 had a significantly increased risk for ICH progression (OR [95% CI]: 2.09 [1.07-4.37]; adjusted p = 0.043). ICH progression was associated with increased need for craniotomy (OR [95% CI]: 3.27 [1.28-8.33]; adjusted p = 0.013) and mortality (OR [95% CI]: 3.41 [1.11-10.53]; adjusted p = 0.033). A platelet count <100,000/m3 was an independent predictor for mortality (OR [95% CI]: 9.5 [1.3-71.4]; adjusted p = 0.029). CONCLUSION: A platelet count <100,000/mm3 is associated with a ninefold adjusted risk of death, and a platelet count <175,000/mm3 is a significant predictor of ICH progression. The impact of early correction of the admission platelet count warrants further validation.

Esophageal Actinomycosis Masquerading as Cancer in an Immunocompetent Patient.

A 79-year-old African American woman presented with acute hematemesis after progressive dysphagia for 6 weeks and 12-pound weight loss. She had no predisposing immunocompromising comorbidity such as the human immunodeficiency virus or active malignancy. Computed tomography showed air-fluid levels within the esophagus with partial obstruction. Upper endoscopy revealed a 1-cm mass lesion in the midthoracic esophagus, and biopsy results surprisingly showed esophageal actinomycosis. The patient's symptoms resolved on antimicrobial therapy at a one-month follow-up, and the lesion was not seen on repeat endoscopy with biopsy at 3 months. We believe that inhaled corticosteroids for chronic obstructive pulmonary disease may have created the growth milieu by impairing local defenses. Correct inhaler technique, avoiding swallowing the water after mouth rinsing, and a spacer device are recommended to reduce esophageal corticosteroid exposure.

A Comparison of Hemostatic Patches Versus Pericardium Allograft for the Treatment of Complex Peyronie's Disease With Penile Prosthesis and Plaque Incision.

OBJECTIVE: To compare outcomes between hemostatic patches (HP) versus pericardium allografts (PA) for complex Peyronie's disease with erectile dysfunction managed with inflatable penile prosthesis (IPP) and plaque incision and grafting (PIG). METHODS: We reviewed all men who underwent IPP with PIG for PD at our institution (4/2010-9/2018). PIG was performed via relaxing tunical incisions during IPP implantation following manual modeling if there was persistent curve >30° and/or significant narrowing. Tunical defects >2 cm were grafted. PA (Coloplast, Minneapolis, MN) or HP consisting of either Evarrest, Nu-Knit (Ethicon Inc., Somerville, NJ), or TachoSil (Baxter Int., Deerfield, IL) were used. RESULTS: HP was placed in 18 men (n = 10 Evarrest, n = 6 Nu-Knit, and n = 2 TachoSil), 15 had PA. There was no difference in mean age, preoperative curvature (HP:75° vs PA:78°), or grafted area (HP:11.9 cm2 vs PA:10.9 cm2) between HP and PA cohorts. Mean operative time was shorter for HP (122 vs 166 minutes, P = .01). Median follow-up: 6.6 months (range: 2-27 months) for HP and 34.6 months (range: 13-103 months) for PA. Residual curvature >20° was present following HP in 16.7% (n = 3) and PA in 13.3% (n = 2; P = 1.0). There were no complications attributable to HP/PA material and no IPP herniation through the tunical defect. Postoperatively, 94.4% (n = 17) of HP and 93.3% (n = 14) of PA patients were engaged in penetrative intercourse (P = 1.0). CONCLUSION: HP are effective materials to cover the tunical defect over an IPP following plaque incision for PD. HP outcomes are similar to PA, while operative time is shorter for HP.

Fiber diffraction as a screen for amyloid inhibitors.

Targeting the initial formation of amyloid assemblies is a preferred approach to therapeutic intervention in amyloidoses, which include such diseases as Alzheimer's, Parkinson's, Huntington's, etc., as the early-stage, oligomers that form before the development of beta-conformation-rich fibers are thought to be toxic. X-ray patterns from amyloid assemblies always show two common intensity maxima: one at 4.7 A corresponding to the hydrogen-bonding spacing between the beta-chains, and the other at approximately 10 A corresponding to the spacing between beta-pleated sheets. We report here the application of fiber x-ray diffraction to monitor these structural indicators of amyloid fiber assembly in the presence of small, aromatic molecules, some of which have been assessed by other techniques as being inhibitory. The compounds included butylated hydroxytoluene, chloramphenicol, cotinine, curcumin, diphenylalanine (FF), ethyl 3-aminobenzoate methane sulfonate, hexachlorophene, melatonin, methylpyrrolidine, morin, nicotine, phenolphthalaine, PTI-00703 (Cat's claw), pyridine, quinine, sulfadiazine, tannic acid, tetracaine, tetrachlorosalicylanilide, and tetracycline. Their effects on the aggregation of Abeta1-40, Abeta11-25, Abeta12-28, Abeta17-28, Abeta16-22, and Abeta16-22[methylated] analogues were characterized in terms of the integral widths and integrated intensities of the two characteristic reflections. Peptide Abeta11-25 with or without small molecules showed varying relative intensities but similar coherent lengths of 28-49 A in the intersheet and 171-221 A in the H-bonding directions. PTI-00703, however, abolished the H-bonding reflection. Among previously reported aromatic inhibitors for Abeta11-25, PTI-00703, tannic acid, and quinine were more effective than curcumin, morin, and melatonin based on the criterion of crystallite volume. For the N-methylated and control samples, there were no substantial differences in spacings and coherent lengths; however, the relative volumes of the beta-crystallites, which were calculated from the magnitude of the intensities, decreased with increase in concentration of Abeta16-22Me. This may be accounted for by the binding of Abeta16-22Me to the monomer or preamyloid oligomer of Abeta16-22. The fiber diffraction approach, which can help to specify whether an amyloidophilic compound acts by impeding hydrogen-bonding or by altering intersheet interactions, may help provide a rationale basis for the development of other therapeutic reagents.

Management of radiation-induced nausea and vomiting.

Management of radiation-induced nausea and vomiting (RINV) includes both prevention and therapy. Primary prevention involves implementation of measures to modify risk factors. Secondary prevention involves prophylaxis and treatment with 5HT(3) receptor antagonists (5HT(3)RAs) with or without corticosteroids, dopamine antagonists, antihistamines, or anticholinergics. 5HT(3)RAs are also useful in treatment of RINV with significantly better outcomes, compared to other antiemetics or placebo. Agents include ondansetron, granisetron, dolasetron, palonosetron, and tropisitron. These agents may be useful in both the radiotherapy patient and the individual who has been accidentally exposed to ionizing radiation.

Nephrometry score matched robotic vs. laparoscopic vs. open partial nephrectomy.

To compare perioperative outcomes in the three most common partial nephrectomy modalities: robotic (RPN), laparoscopic (LPN), and open (OPN), matched for nephrometry scores. Patients aged 16-85 who underwent RPN, LPN, or OPN from 2007 to 2014 for localized renal carcinoma within our healthcare system were enrolled. Age, sex, body mass index, and Charlson Comorbidity Index (CCI) as well as perioperative outcomes of estimated blood loss (EBL), length of hospital stay (LOS), ischemia time (IT), change in eGFR, positive margin rate, operative time (OT), and emergency room visit rates were compared between RPN, LPN, and OPN using the R.E.N.A.L nephrometry score. A total of 862 patients underwent partial nephrectomy (523 LPN, 176 OPN, and 163 RPN). Patients who underwent OPN were significantly older, and had higher nephrometry scores and CCI. When matched for nephrometry scores, minimally invasive (LPN and RPN) compared to OPN had lower EBL (< 0.0001), shorter LOS (< 0.0001), shorter IT (< 0.001), and less change in eGFR (< 0.001), particularly in nephrometry scores higher than 8 (0.0099). Comparing RPN with LPN, RPN had significantly shorter OT in all nephrometry scores (< 0.001); shorter IT and LOS in nephrometry scores higher than 7. Our study suggests that minimally invasive partial nephrectomy may have superior outcomes to OPN when matched by nephrometry scores, particularly at higher scores and for RPN. This finding may contribute to a surgeon's decision in the approach to partial nephrectomy.

Hepatitis C Infection Patterns at a Tertiary Care Center in New York: A Cross-Sectional Study.

Introduction In the United States, 2.7 to 3.9 million patients are infected with the hepatitis C virus (HCV) with 3,500 new cases reported yearly. According to the Centers for Disease Control and Prevention, HCV was the underlying or contributing cause of death of 19,659 patients in 2014. These facts underscore the need for a better understanding of the scope of this disease. Our epidemiologic study aimed at analyzing the pattern of occurrence of HCV infection at Staten Island University Hospital (SIUH) by evaluating the characteristics of newly infected patients with hepatitis C in 2014. The identified features served to better distinguish the targets for preventive health care in our particular population. Methodology A cross-sectional study of all newly diagnosed patients with HCV infections in the year 2014 presenting to SIUH was conducted using International Classification of Disease-9 codes (ICD-9) for hepatitis C. We included all patients with a positive HCV antibody confirmed by polymerase chain reaction testing. Patients were divided into groups according to age to simulate the age groups in the 2013 - 2014 Hepatitis B and C Annual Report of the New York City (NYC) Department of Health and Mental Hygiene published in 2016 (abbreviated to 2014 NYCDOH Report, hereafter). Gender and HCV genotypes were also collected. We compared disease frequency between age groups, gender, and genotype with the results of the 2014 NYCDOH Report. Results A total of 378 newly diagnosed HCV cases were identified; 60.05% were men, and 39.95% were women. The rate of infection with genotype 1a was the highest (36. 5%) followed by 1b (25.9%). In women, genotype 1b was predominant (13.76%) versus genotype 1a as the most common in men. The mean age was 54 years for men and 57 years for women. Most cases fell into the 60 to 69-year age group (32.28%), followed by the 50 to 59-year age group (31.48%). More so, all patients 80 years and older were exclusively women. Conclusions We found most new HCV infections at SIUH were diagnosed in patients aged 60 to 69 years, and the 2014 NYC DOH Report indicates most new HCV infections occur in patients aged 40 to 59 years. Also, all HCV infections detected in patients older than 80 years of age were found in women. These findings provide a better understanding of the patient demographics for appropriate HCV screening policies. Increased awareness and strict adherence to screening policies in baby boomers and high-risk populations are paramount in order to diagnose HCV infection early, offer therapy, and prevent HCV-related mortality and morbidity.
