Abstract Background Varicocele is an abnormally dilated pampiniform plexus of the veins within the spermatic cord and is considered the most common correctable cause of male factor infertility. Many approaches are described for treatment either surgical (tradition inguinal, subinguinal, and laparoscopic) or non-surgical percutaneous embolization. During the period from August 2017 to December 2018, we prospectively analyzed the preoperative and post-operative alteration of semen parameters (at 3 and 9 months) of the data collected from 63 patients with clinically evident varicocele referred to our tertiary hospital. Patients were divided into two groups: group 1, thirty-three patients who underwent subinguinal microsurgical ligation, and group 2, thirty patients who underwent percutaneous embolization. Results Sixty-three patients enrolled in this study were divided in two groups: group 1, patients who underwent surgery, and group 2, patients who underwent embolization; the mean age is 24.6 ± 1.27 years in group 1 and 23.7 ± 2 years in group 2; there was no statistically significant difference between the two groups as regards BMI, diabetes, hypertension, and smoking. Bilaterality was present in 15.2% of group 1 patients and 10% in group 2 patients (P value 0.06). Most of the patients were classified as grades 2 and 3 with no statistical significance regarding severity of the disease. Preoperative semen parameters for patients including sperm count, motility, and abnormal forms showed no statistically significant difference between the two groups. Post-intervention semen analysis was done twice during follow-up after 3 months and 9 months from the date of intervention. After 3 months, the semen parameters were improved in both groups in spite of the higher sperm count in group 2 but with no statistical significance. After 9 months follow-up, semen analysis showed persistent increase in sperm mobility in group 1 patients in comparison to group 2 patients. Both groups had better improvement in count of normal form with no statistical significant change. Conclusion Improvement of semen parameters while treating primary varicocele by either subinguinal microsurgery approach or percutaneous embolization shows equivalent outcomes.

Introduction: Hematoma expansion (HE) is an established predictor of mortality and poor functional outcome after intracerebral hemorrhage (ICH). The computed tomography angiography (CTA) “spot” sign predicts HE and deterioration. The “dot” sign on delayed post-contrast CT (PCCT) has undetermined clinical significance but is thought to represent a slower rate of bleeding than the “spot” sign. We aimed to compare the sensitivity of a “dot” sign with the “spot” sign and establish the clinical significance of the “dot” sign. Methods: Patients with ICH presenting to our center July 2008-May 2013 were identified from our stroke registry. Only patients with baseline CT, CTA and PCCT and follow-up CT 6-36 hours later were included. Patients with clot evacuation between baseline and follow-up CT were excluded. HE was defined as 1) any ≥ 1cc increase and 2) significant ≥ 12.5cc increase or >33% increase in volume. Differences in cohort characteristics were assessed using appropriate statistical tests and sensitivity was calculated from 2x2 tables. Unadjusted logistic regression models were used to investigate the relation of “spot” and “dot” signs with HE and poor functional outcome (discharge mRS 4-6). Results: Of the 210 ICH patients included in the analyses (median age 61, 44.7% female, 66.2% black), 39 (18.5%) patients had a PCCT “dot” sign and 19 (9%) had a CTA “spot” sign. Significant HE occurred in 15% with “dot” sign and 8% with “spot” sign. The PCCT “dot” sign had a sensitivity of 0.52 in predicting significant HE and a sensitivity of 0.69 in predicting discharge mRS 4-6 (compared with 0.24 and 0.30 for “spot” sign, respectively). Patients with a “dot” sign, but without a “spot” sign, had significantly increased odds of any HE (OR 5.7, 95% CI 1.9-17.8, p=0.003), mRS 4-6 (OR 8.1, 95% CI 1.03-64.6, p=0.048), and death (OR 8.1, 95% CI 1.4-48.4, p=0.02), but not significant HE (OR 2.2, 95% CI 0.7-6.7, p=0.15). Conclusions: The PCCT “dot” sign was more sensitive in predicting hematoma expansion than the CTA “spot” sign and predicted hematoma expansion and poor functional outcome even in the absence of the “spot sign.” The utility of PCCT imaging in acute evaluation of ICH patients requires validation, but our study supports clinical relevance of the “dot” sign.

Introduction: Unplanned hospitalizations are commonly associated with a circulating troponin concentration >99 th percentile upper reference limit (URL). In order to better understand the clinical significance of troponin elevation, we evaluated outcomes in hospitalized patients according to cardiac endotype. Methods: We prospectively screened consecutive hospitalized patients with elevated high-sensitivity troponin-I (hs-TnI) concentrations (Abbott ARCHITECT troponin-I assay; sex-specific URL, 99 th centile: male: >34ng/L; female: >16ng/L) within a regional cardiac care network (population 650,000). A cardiology clinical team adjudicated individual patient records and assigned endotypes by consensus agreement according to the Fourth Universal Definition of Myocardial Infarction (MI). Endotypes were sub-classified into etiological category by inciting event(s). Characteristics and comorbidity were compared and outcomes recorded on virtual follow-up until June 2 nd 2020. Results: A total of 390 consecutive patients with ≥1 hs-TnI value >URL between March 1-April 15, 2020, were evaluated; 44 patients were excluded ( Duplicates: 2; Missing data: 41; Research patient: 1 ). Of 346 who qualified for inclusion, an index diagnosis of Type 1 MI (T1MI), T2MI and myocardial injury were assigned in 115 (33.2%), 79 (22.8%) and 152 (43.9%) patients, respectively. Compared with T1MI, patients with T2MI and myocardial injury had lower peak hs-TnI values (median [IQR]: 86 [250-697] vs 5020 [853-7774]ng/L; p< 0.01), lower estimated 10-year survival (40.2% vs 53.4%; p=0.002), less frequently underwent coronary revascularization (1.4% vs 45.2%; p<0.0005) and had longer inpatient stay (13.0 vs 6.1 days). Inpatient and overall mortality rates from admission to follow-up (median [range]: 71 [0-151] days) were higher among patients with T2MI and myocardial injury (19.9% vs 7.8%; p=0.004; and 26.0% vs 11.3%; Log rank (Mantel-Cox) X 2 = 1.927; p=0.003) independent of similar cardiovascular risk profiles. Conclusions: Despite lower peak circulating troponin concentrations, patients with T2MI and myocardial injury had higher inpatient mortality, lower estimated 10-year survival and longer in-hospital stay compared to those with T1MI.

Abstract Study question Is the SARS-CoV–2 virus present in human semen and what is the impact on semen parameters following an infection? Summary answer SARS-CoV–2 infection, though not detected in semen of recovered men, can affect TSN in ejaculate in the acute setting. What is known already Early epidemiological data has suggested that the primary mode of transmission is through respiratory droplets, but the presence of SARS-CoV–2 has been identified in other bodily fluids such as feces, urine, and semen. Study design, size, duration We prospectively recruited thirty men diagnosed with acute SARS-CoV–2 infection using real-time reverse transcriptase-polymerase chain reaction (RT-PCR) of pharyngeal swab specimens. Thirty semen samples from recovered men were obtained 11–64 days after testing positive for SAR-CoV–2 infection. The median duration between positive SAR-CoV–2 test and semen collection was 37 days (IQR=23). Participants/materials, setting, methods Semen samples were collected from each individual using mailed kits. Follow-up semen samples were done with mailed kits or in-person in office setting. Semen analysis and PCR was performed after samples were received. Main results and the role of chance The median total sperm number (TSN) in ejaculate was 12.5 million (IQR=53.1). When compared with age-matched SARS-CoV–2(-) men, TSN was lower among SARS-CoV–2(+) men (p = 0.0024). Five men completed a follow-up sperm analysis (median 3 months) and had a median TSN of 18 million (IQR=21.6). No RNA was detected by means of RT-PCR in the semen in 16 samples tested. Limitations, reasons for caution First, most of the semen samples came from non-severe men of whom were in the recovery stage and lacked symptoms. Additionally, our sample size was relatively small and overnight mail-in semen analysis kits were used during the acute phase of infection to minimize contact with positive subjects. Wider implications of the findings: Our findings suggest extremely low risk of viral transmission during sexual contact and assisted reproductive techniques, although further data need to be obtained. The impact on TSC in recovered men from SARS-CoV–2 infection is concerning, nevertheless long-term follow-up of these men is critical to determine the nadir of TSC.

Post-vasectomy semen analysis (PVSA) is the procedure used to establish whether sperm are present in the semen following a vasectomy. PVSA is presently carried out by a wide variety of individuals, ranging from doctors and nurses in general practitioner (GP) surgeries to specialist scientists in andrology laboratories, with highly variable results.Key recommendations are that: (1) PVSA should take place a minimum of 12 weeks after surgery and after a minimum of 20 ejaculations. (2) Laboratories should routinely examine samples within 4 h of production if assessing for the presence of sperm. If non-motile sperm are observed, further samples must be examined within 1 h of production. (3) Assessment of a single sample is acceptable to confirm vasectomy success if all recommendations and laboratory methodology are met and no sperm are observed. Clearance can then be given. (4) The level for special clearance should be <100 000/mL non-motile sperm. Special clearance cannot be provided if any motile sperm are observed and should only be given after assessment of two samples in full accordance with the methods contained within these guidelines. Surgeons are responsible both preoperatively and postoperatively for the counselling of patients and their partners regarding complications and the possibility of late recanalisation after clearance. These 2016 guidelines replace the 2002 British Andrology Society (BAS) laboratory guidelines and should be regarded as definitive for the UK in the provision of a quality PVSA service, accredited to ISO 15189:2012, as overseen by the United Kingdom Accreditation Service (UKAS).
