This study examined the relationship between stimulant medications used for the treatment of attention deficit hyperactivity disorder and semen parameters. We performed a retrospective cohort study at a large, academic institution between 2002 and 2020. We included men with a semen analysis without prior spermatotoxic medication use, empiric medical therapy exposure or confounding medical diagnoses (varicocele, Klinefelter's syndrome, cryptorchidism, cystic fibrosis, diabetes, cancer or cancer- related treatment, and azoospermia). Men were stratified by stimulant exposure (methylphenidate or amphetamines). A multivariable linear regression was fit to assess the association between individual semen parameters, age, stimulant exposure and non- stimulant medication use. Of 8,861 men identified, 106 men had active prescriptions for stimulants within 90 days prior to semen testing. After controlling for age and exposure to non- stimulant medications, stimulant use was associated with decreased total motile sperm count (β: 18.00 mil/ejaculate and standard error: 8.44, p = 0.033) in the setting of decreased semen volume (β: 0.35 ml, and standard error: 0.16, p = 0.035), but not sperm concentration, motility and morphology. These findings suggest a role for reproductive physicians and mental health providers to consider counselling men on the potential negative impact of stimulants prescribed for attention deficit hyperactivity disorder on semen volume during fertility planning.

Laser-photolysis - laser-induced-fluorescence methods are used to characterize the collisional energy transfer between CN (A 2PI(sub i) and (X 2sigma+) states and to measure radiative lifetimes of the (A 2PI(sub i) v prime = 2-7 vibrational levels. In addition, use of the A 2PI(sub i) arrow to the left X 2sigma+ system for the laser-induced-fluorescence determination of (X 2sigma+) populations is demonstrated and discussed.

A recent study conducted by Punjani et al examined the effectiveness of gabapentin for postoperative pain relief and opioid reduction in male reproductive scrotal surgery. The study found that gabapentin was effective in reducing pain immediately after surgery, but did not result in a significant difference in opioid use compared to the control group. The study also highlighted the potential adverse effects of gabapentin and questioned its role as a mainstay of perioperative analgesia for male reproductive surgery. The authors emphasized the importance of opioid-sparing analgesia in reproductive surgery and suggested that achieving opioid-free analgesia should be the goal. [Extracted from the article]

The basic principles of vasal reconstruction have endured since their initial description over a century ago, yet the nuances and technical approaches have evolved. Prior to performing vasectomy reversal, the clinician should perform a focused history, physical and laboratory assessment, all of which are critical for patient counseling and preoperative planning. Operative success is contingent on appropriate intraoperative decision making and technical precision in completing a tension-free, watertight, and patent anastomosis. Outcomes of vasectomy reversal differ on the basis of the type of reconstruction required, reconstructive technique, and patient-specific factors. Here we review the indications, surgical techniques, and outcomes of vasectomy reversal. [ABSTRACT FROM AUTHOR]

Background: Capsular contracture is a challenging problem for plastic surgeons despite advances in surgical technique. Breast pocket irrigation decreases bacterial bioburden. Studies have shown that hypochlorous acid (HOCl; PhaseOne Health, Nashville, TN) effectively penetrates and disrupts biofilms; however, there are limited clinical data regarding this irrigation in breast augmentation.Objectives: The aim of this study was to investigate the effects of HOCl pocket irrigation in revision breast augmentation by evaluating rates of capsular contracture recurrence, infection, and allergic reactions.Methods: We performed an institutional review board-approved retrospective chart review of revision breast augmentation cases for Baker grade III/IV capsular contractures in which pockets were irrigated with HOCl. Data were obtained from 3 board-certified plastic surgeons.Results: The study included 135 breasts in 71 patients, who ranged in age from 27 to 77 years (mean, 53.7 years). Follow-up ranged from 12 to 41 months (mean, 20.2 months). Postoperatively, there were 2 unilateral Baker grade III/IV recurrences at 13 months and 1 bilateral Baker grade II recurrence at 3 months. There were no infections or allergic reactions. The overall Baker grade III/IV capsular contracture recurrence rate was 0% at 12 months and 1.5% at 15 months.Conclusions: Breast pocket irrigation decreases bioburden, which may influence capsular contracture recurrence. We evaluated 3 varied applications of HOCl in revision aesthetic breast surgery and found a low capsular contracture recurrence rate and no adverse reactions. We plan to report our findings with HOCl in primary breast augmentation in the future, and other studies are being conducted on the efficacy of HOCl in aesthetic surgery.Level Of Evidence:4: [ABSTRACT FROM AUTHOR]

The study on the molecular oxygen in supersonic seeded beams by V. Aquiliani et al. is problematic. Their findings disagree with those in the study by Harich and Wodtke in terms of the alignment of CO in a supersonic beam. Moreover, the highest polarizations reported by V. Aquiliani et al. are physically impossible and the lower alignment polarization cases they presented give improbable distributions.
