Factors related to promotion of physical activity in clinical oncology practice: A scoping review.

OBJECTIVES: To map which factors have been considered, explored, and found to influence physical activity (PA) promotion by oncology physicians and nurses (OPN). METHODS: A scoping review of empirical studies was conducted using Arksey and O'Malley's framework and the PRISMA-ScR guideline. The quality of the studies was evaluated using the QATSDD tool. RESULTS: Twenty-nine publications were included. The methodological quality of the studies was low to moderate. Studies have shown a positive attitude towards PA and recommending PA. PA knowledge seems to influence PA promotion by OPNs to some extent. Structural barriers for PA promotion are the most endorsed barriers but to what extent they influence PA promotion is unclear. The demographic and professional characteristics of OPNs and their PA behavior do not seem to influence PA promotion to a greater extent. Patients' PA interest, health characteristics, and medical conditions are additional factors. Their implications for PA promotion are not fully elucidated. CONCLUSIONS: The varied results across the studies, together with the methodological limitations of the studies, make it unclear to what extent the explored factors influence PA promotion by OPNs. PRACTICE IMPLICATIONS: More research into what influences OPNs' engagement in PA promotion is warranted to support clinical PA promotion.

Vibratory ejaculation in 140 spinal cord injured men and home insemination of their partners.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: Anejaculation is commonly found in spinal cord injured (SCI) men. Clinical treatments and assisted reproductive techniques allow SCI men to father children but few home pregnancies have been reported. The objective of this paper is to evaluate the results from the last 20 years' of treatment with penile vibratory stimulation (PVS) and vaginal self-insemination at home in SCI men and their partners. SETTING: The data originate from two European centers and one American center. METHODS: A total of 140 SCI men with anejaculation and their healthy partners were available for this analysis. Men who obtained antegrade ejaculation by PVS and had motile sperm in the ejaculate were offered the possibility of PVS combined with vaginal self-insemination at home. Couples were instructed to perform PVS and to instill the ejaculate intravaginally. Outcome measures were pregnancy rate per couple, number of live births, total motile sperm count and time to pregnancies. RESULTS: Median total motile sperm count was 29 million (range, 1-92 million). In all, 60 of the 140 couples (43% pregnancy rate) achieved 82 pregnancies. Seventy-two of the pregnancies resulted in live births with the delivery of 73 healthy babies. Median time to first pregnancy was 22.8 months (6.0-98.4). No complications were reported. CONCLUSION: PVS combined with vaginal self-insemination may be performed as a viable, inexpensive option for assisted conception in couples in whom the SCI male partner has an adequate total motile sperm count and the female partner is healthy.

Multiple needle-pass percutaneous testicular sperm aspiration as first-line treatment in azoospermic men.

Percutaneous testicular sperm aspiration (TESA) has been known for decades as a simple, minimally invasive approach to sperm retrieval in azoospermic men. Because of lower reported sperm retrieval rates (SRR) when compared with microdissection testicular sperm extraction (mTESE), many centers now use mTESE as the first choice for retrieving spermatozoa in nonobstructive azoospermia (NOA). Objectives of this study were to evaluate the outcome and safety of TESA and mTESE in the treatment of azoospermia and to investigate the usefulness of a prognostic TESA to individualize protocols for couples and limit the use of invasive testicular procedures. IRB approval was obtained to retrospectively evaluate 208 patients undergoing multiple needle-pass TESA between 1999 and 2014. Prognostic TESA was performed on 125 men with NOA and 82 with obstructive azoospermia (OA). Nine NOA men and 31 OA men with previously demonstrated spermatozoa had a subsequent therapeutic TESA while nine NOA men with a failed TESA proceeded to mTESE. Main outcome measures were complication rates and SRR. SRR of the prognostic TESA was 30% (38/125) for NOA men and 100% (82/82) for OA men. Eight/nine NOA men and 31/31 OA men had spermatozoa found for intracytoplasmic sperm injection in a subsequent therapeutic TESA. In nine NOA men in whom a TESA produced no spermatozoa, only one had spermatozoa found with mTESE. Overall complication rates of TESA and mTESE were 3% (7/267) and 21% (3/14), respectively. TESA provides reasonable SRR and is a safe procedure. Successful prognostic TESA indicates future success with therapeutic TESA. Men with a failed TESA have a limited chance of sperm retrieval using mTESE. Approaching azoospermic men with an initial prognostic TESA followed by either therapeutic TESA and/or mTESE is an efficient algorithm in the management of azoospermia and limits the use of more invasive procedures.

The effect of penile vibratory stimulation on male fertility potential, spasticity and neurogenic detrusor overactivity in spinal cord lesioned individuals.

PURPOSE: Present the possibility for treatment of male infertility, spasticity, and neurogenic detrusor overactivity in spinal cord lesioned (SCL) individuals with penile vibratory stimulation (PVS). METHOD: Obtaining reflex-ejaculation by PVS, by using a vibrator developed for this purpose. The stimulation was performed with a vibrating disc of hard plastic placed against the frenulum of the penis (amplitude > or = 2.5 mm). The vibration continued until antegrade ejaculation or for a maximum of 3 minutes followed by a pause of 1 minute before the cycle was repeated, maximally 4 times. RESULTS: >80% SCL men are able to obtain ejaculation with PVS. Pregnancy rates obtained with home PVS and intra-vaginal insemination was 22-62% (4 studies), and with PVS or electroejaculation and intrauterine insemination/in-vitro fertilization/intracytoplasmatic sperm injection 39-64% (9 studies). PVS was demonstrated to decrease spasticity significantly when measured by the modified Ashworth scale. In addition, a decrease of the number of spontaneous EMG events which probably indicate spasms was observed. Increase in bladder capacity at leakpoint following 4 weeks of frequent ejaculation with PVS treatment was likewise demonstrated. CONCLUSION: PVS has proved its importance for SCL male fertility, in the years to come its place in treatment of spasticity and neurogenic detrusor overactivity has to be established.

Quality of semen obtained by penile vibratory stimulation in men with spinal cord injuries: observations and predictors.

OBJECTIVES: To study the semen quality and to examine prognostic factors that may affect semen quality in men with spinal cord injuries (SCI) who respond to penile vibratory stimulation (PVS). METHODS: Fifty-one PVS responders were prospectively examined. Penile vibratory stimulation was induced with optimized vibration parameters. Semen quality was characterized by semen analysis. The gel agglutination test for the presence of antisperm antibodies and serum hormone assays were performed. Characteristics of the spinal lesions, type of bladder management, and hormone assays were compared to semen quality and incidence of azoospermia or total lack of motility. RESULTS: The mean semen parameters were: volume-1.9 mL (range 0.2 to 7.0); total sperm-457 million (range 0 to 10,900); motility-12.6% (range 0% to 55%); total motile sperm-39.3 million (range 0 to 401); normal morphology-50.1% (range 0% to 90%). Better sperm motility was seen in men with cervical lesions versus those with thoracic lesions (16% versus 7%) and incomplete versus complete lesions (19% versus 10%). There was a higher incidence of azoospermic specimens in men with thoracic lesions versus cervical level (26% versus 3%) and a lower incidence of finding any motile sperm in the specimen (47% versus 81%). Men voiding without catheters had a lower incidence of azoospermia (3% versus 28%). Abnormalities of hormone and antibody tests were rare. CONCLUSIONS: Better sperm specimens from PVS of men with SCI may be expected from men with higher neurologic level, incomplete lesions, and those voiding without the use of a catheter. Hormonal abnormalities and immunologic causes do not explain the poor sperm quality seen in men with SCI.

False iliac artery aneurysm following renal transplantation.

We report a very rare case of a false iliac artery aneurysm following renal transplantation. The patient was a 51-year-old women who presented with a painful 10 x 10 cm pulsating mass in her left iliac fossa. The patient had received a second cadaveric renal transplantation 5 years previously. The graft never functioned and transplant nephrectomy was performed 2 weeks later. A CT-scanning showed a 10 x 10 cm large aneurysm arising from the left external iliac artery. At operation a large false aneurysm was identified arising from the original transplant anastomotic site. Due to the extent of the aneurysms, a Gortex graft was inserted between the external iliac artery and the common femoral artery. The patient made an uneventful post-operative recovery.

[Intracavernous self-injection for treatment of erectile dysfunction inpatients with spinal cord injuries]. / Intrakavernøs selvinjektion til behandling af erektiv dysfunktion hos rygmarvsskadede.

Twelve patients (aged 18-70 years, average 41 years) with known spinal cord lesions with durations of 1-25 years and with levels of the lesions from C II incomplete to L III complete received intracavernous injection of papaverine with a commencing dose of 15 mg papaverine. Following this, nine patients could obtain usable erection lasting from 30 to 300 minutes with doses from 15-60 mg. In one patient, however, 60 mg papaverine was supplemented by 5 mg phentolamine. The patients were then trained in the technique of self-injection. On contact 1-37 months after the primary instruction, eight patients had performed a total of 40 self injections with the object of coitus, which was successful in all of the cases. Because he had no partner, one patient had no employed self-injection but would like to employ the method if the appropriate situation arose. Two patients did not want to continue self-injection. One of these considered that the method was too complicated to use and the other had had an episode of prolonged erection requiring treatment. No other side effects requiring treatment were observed. The relationship to possible partners and the experience of libido, "orgasm" and feeling of self esteem as compared to previous experiences were registered. Six out of nine patients had experienced improvement in at least one of these fields and none had experienced deterioration. A total of seven patients planned to employ the method in future. The authors conclude that self-injection of papaverine is a promising supplement in the treatment of erective dysfunction in patients with spinal cord lesions.

[Vibration-induced reflex ejaculation in patients with spinal cord injuries]. / Vibrationsfremkaldt refleksejakulation hos rygmarvsskadede.

Thirty-six men (aged 18-42 years, average age 27 years) with known spinal cord lesions for 0.3-39 years and levels of the lesions from C3 incomplete to L1 complete were submitted to penile vibrations with the objective to obtain reflex ejaculation. Sperm cells were demonstrated in a total of 27 of the participants, antegrade ejaculation in 16 cases and 11 retrograde ejaculations. In general, the semen quality was very poor with reduced total number of spermatozoa and increased percentage of immobile and/or morphologically abnormal spermatozoa compared with normal values. In connection with the vibration procedures, three cases of autonomous hyperreflexia followed by transient slight headache which did not require treatment occurred while an isolated case was treated with 0.5 mg glycerine nitrate (Nitromex) administered sublingually with good effect. No other side effects were observed.

[Ejaculation induced by electrostimulation in men with spinal cord injuries]. / Elektrostimulation til frembringelse af ejakulation hos rygmarvsskadede maend.

Five men (aged 29-43 years) with ejaculatory dysfunction and spinal cord injuries for 10-41 years and level of complete lesions from C6 to T10 underwent electrostimulation. Antegrade ejaculate was obtained in all five participants and simultaneous retrograde ejaculation in four. In general, the total number of spermatozoa was greatest in the retrograde ejaculates and highly variable between the subjects both in the antegrade (0.2-5330 mill.) and in the retrograde ejaculates (0.4-5690 mill.). The percentage of immobile and morphologically abnormal spermatozoa was increased compared with normal values. In connection with the electrostimulation procedures no cases of autonomous hyperreflexia or rectal mucosal injury were observed.

Perceptions and opinions of men and women on a man's sexual confidence and its relationship to ED: results of the European Sexual Confidence Survey.

The European Sexual Confidence Survey examined the opinions of men and women on the link between a man's sexual confidence and functional (erectile and orgasmic) and emotional (satisfaction and self-confidence) aspects of sex and life in general. The online survey of sexually active adults (25-64 years of age) was conducted in 12 European countries using multiple-choice questions and predefined statements on sexual confidence. Erectile function was assessed by erection hardness score (EHS). Of 8576 respondents (4246 men, 4330 women), 23.9% reported non-optimal erectile hardness (EHS3) for themselves or their partners. 79.0% believed that an ability to sexually satisfy their partner is most closely linked to a man's sexual confidence. One in three linked a man's sexual confidence to erection hardness and ability to reach orgasm. The majority (∼94.0%) believed that it is important for a man to be sexually confident for good sex and that being able to have good sex enables men to have greater satisfaction with life overall. Lack of sexual confidence due to insufficient erection rigidity was considered by most respondents (∼65.0%) to reduce a man's confidence about the next sexual encounter and also his self-confidence and self-esteem overall.

International standards to document remaining autonomic function after spinal cord injury.

STUDY DESIGN: Experts opinions consensus. OBJECTIVE: To develop a common strategy to document remaining autonomic neurologic function following spinal cord injury (SCI). BACKGROUND AND RATIONALE: The impact of a specific SCI on a person's neurologic function is generally described through use of the International Standards for the Neurological Classification of SCI. These standards document the remaining motor and sensory function that a person may have; however, they do not provide information about the status of a person's autonomic function. METHODS: Based on this deficiency, the American Spinal Injury Association (ASIA) and the International Spinal Cord Society (ISCoS) commissioned a group of international experts to develop a common strategy to document the remaining autonomic neurologic function. RESULTS: Four subgroups were commissioned: bladder, bowel, sexual function and general autonomic function. On-line communication was followed by numerous face to face meetings. The information was then presented in a summary format at a course on Measurement in Spinal Cord Injury, held on June 24, 2006. Subsequent to this it was revised online by the committee members, posted on the websites of both ASIA and ISCoS for comment and re-revised through webcasts. Topics include an overview of autonomic anatomy, classification of cardiovascular, respiratory, sudomotor and thermoregulatory function, bladder, bowel and sexual function. CONCLUSION: This document describes a new system to document the impact of SCI on autonomic function. Based upon current knowledge of the neuroanatomy of autonomic function this paper provides a framework with which to communicate the effects of specific spinal cord injuries on cardiovascular, broncho-pulmonary, sudomotor, bladder, bowel and sexual function.

Sexual function in spinal cord lesioned men.

STUDY DESIGN: Review of literature. OBJECTIVE: To review the physical aspects related to penile erection, ejaculatory dysfunction, semen characteristics, and techniques for enhancement of fertility in spinal cord lesioned (SCL) men. SETTING: Worldwide: individuals with traumatic as well as non-traumatic SCL. RESULTS: Recommendations for management of erectile dysfunction in SCL men: If it is possible to obtain a satisfactory erection but of insufficient duration, then try to use a venous constrictor band to find out if this is sufficient to maintain the erection. Otherwise we recommend Sildenafil. If Sildenafil is not satisfactory then use intracavernous injection with prostaglandin E(1) (some SCL men may prefer cutaneous or intraurethral application). We discourage the implantation of penile prosthesis for the sole purpose of erection. Recommendations for management of ejaculatory dysfunction in SCL men: Penile vibratory stimulation (PVS) to induce ejaculation is recommended as first treatment choice. If PVS fails, SCL men should be referred for electroejaculation (EEJ). Semen characteristics: Impaired semen profiles with low motility rates are seen in the majority of SCL men. Recently reported data gives evidence of a decline in spermatogenesis and motility of ejaculated spermatozoa shortly after (few weeks) an acute SCL. It is suggested that some factors in the seminal plasma and/or disordered storage of spermatozoa in the seminal vesicles are mainly responsible for the impaired semen profiles in men with chronic SCL. Fertility: Home insemination with semen obtained by PVS and introduced intravaginally in order to achieve successful pregnancies may be an option for some SCL men and their partners. The majority of SCL men will further enhance their fertility potential when using either PVS or EEJ combined with assisted reproduction techniques such as intrauterine insemination or in vitro fertilization with or without intracytoplasmic sperm injection.

Semen quality in the same man before and after spinal cord injury. Case report.

The fertility of spinal cord injured men is severely impaired due to ejaculatory dysfunction and poor semen quality. No previous reports comparing the semen quality in the same man before and after spinal cord injury have been found in the literature. We present a case of a tetraplegic man who 8 months after his spinal cord injury had a deteriorated semen quality compared to a normal semen quality analysed 16 months before the injury.

What are the chances of infertility and should sperm be banked?

Patients with testicular cancer have an excellent chance of surviving and may very well be interested in future fertility. This future fertility may be complicated by both pretreatment and treatment-related subfertility. The risk of ejaculatory dysfunction from retroperitoneal lymph node dissection (RPLND) for low-stage disease has been nearly erased by nerve-sparing techniques. In those patients with an ejaculation, electroejaculation and artificial insemination is effective. With cisplatinum-based chemotherapy, nearly all patients will become azoospermic with the majority recovering spermatogenesis within four years. Most patients undergoing prophylactic radiation therapy for seminoma will return to baseline semen quality within 2 years. In men with persistent poor semen quality, assisted reproductive technologies may allow having children, even with very low numbers of viable sperm. Assisted reproductive technologies have also greatly improved the chance of pregnancy with cryopreserved sperm. Therefore, prospects for procreation are quite good for men facing treatment for germ cell tumors. In those patients who do not recover spontaneous fertility, semen cryopreservation gives additional hope for having children. Patients should be given the option of semen cryopreservation if any viable sperm are present, even if the specimen is extremely poor.

Transcutaneous nitroglycerin in the treatment of erectile dysfunction in spinal cord injured.

We have tested the erectile effect of penile applicated nitroglycerin plasters (Transiderm-Nitro 10 mg/24 hours) in 17 spinal cord injured men, who had responded to intracavernous papaverine injections with erections sufficient for vaginal penetration. The nitroglycerin plasters were applied on the skin of the penile shaft and a positive response was obtained in 12 men. A total of 5 men reported an erectile response sufficient for vaginal penetration after using nitroglycerin plasters at home. All 5 preferred to continue with this noninvasive treatment compared to papaverine injections. Our results indicate that men with spinal cord injury who need doses larger than 15 mg papaverine to obtain erection sufficient for vaginal penetration will not achieve this with nitroglycerin plasters. We suggest that this noninvasive treatment should be tested on spinal cord injured men before injection therapy is initiated.

Sphincteric events during penile vibratory ejaculation and electroejaculation in men with spinal cord injuries.

PURPOSE: We investigate internal and external sphincter responses during penile vibratory stimulation and electroejaculation in men with spinal cord injury. MATERIALS AND METHODS: Ejaculation induction with simultaneous recording of external and internal sphincter pressures was performed in 9 spinal cord injured men. Of the patients with upper motor neuron lesions 3 underwent penile vibratory stimulation and 3 underwent electroejaculation. In 3 men who did not respond to PVS, including 1 with upper motor neuron and 2 with lower motor neuron lesions, penile vibratory stimulation and subsequent electroejaculation were performed. RESULTS: In successful penile vibratory stimulation and electroejaculation upper motor neuron cases external sphincter pressure first reached a peak (average 180 cm. H2O) and subsequently decrease followed in 3 to 10 seconds by a peak in internal sphincter pressure (average 178 cm. H2O), which exceeded external sphincter pressure and ejaculation occurred. During electroejaculation, the pattern progressed, despite complete discontinuation of electrical stimulation. In electroejaculation, there was a trend for a more rapid return of external sphincter pressure greater than internal sphincter pressure, which may explain the electroejaculation retrograde fraction. In nonresponders external sphincter pressure never increased to more than 105 cm. H2O in response to penile vibratory stimulation and no ejaculation was induced. In nonresponders to penile vibratory stimulation, electroejaculation induced a typical sustained increase in internal sphincter pressure and external sphincter pressure but at lower peak pressures. CONCLUSIONS: Forceful contraction of the external sphincter followed by contraction of the internal sphincter always precedes ejaculation during electroejaculation and penile vibratory stimulation. Similarities between penile vibratory stimulation and electroejaculation suggest that the latter induces ejaculation via a complex neurological pathway rather than by simple direct end organ stimulation. The sustained nature of the response to electroejaculation suggests that electrical stimulation should be stopped completely during ejaculation to allow more relaxation of the external sphincter, as this may lead to a decrease in the retrograde fraction.
