Hysterectomy and sexual function: a systematic review and meta-analysis

BACKGROUND

Sexual function after hysterectomy can be a concern for patients, and research remains inconclusive about changes in sexual function associated with hysterectomy.

AIM

We meta-analyzed studies on change in sexual function from pre- to posthysterectomy and the role of total vs subtotal hysterectomy and concomitant bilateral salpingo-oophorectomy (BSO) in differences in such change.

METHODS

We searched PubMed, Embase, and Cochrane databases from inception to January 2022. Two reviewers screened and included studies if they were published in a peer-reviewed journal and reported on sexual function pre- and posthysterectomy for benign nonprolapse indication. Methodological quality was assessed with the STROBE checklist. We used random effects multilevel models to meta-analyze standardized mean differences in pre- to postoperative sexual function and the posthysterectomy Female Sexual Function Index mean across study groups in R (RStudio).

OUTCOMES

Outcomes included overall sexual function, dyspareunia, desire, arousal, lubrication, and orgasm.

RESULTS

Thirty-two articles were analyzed: 8 randomized controlled trials, 20 prospective studies, 2 retrospective studies, 1 cross-sectional study, and 1 secondary analysis, comprising a total of 4054 patients. Each study provided data for at least 1 outcome. Study quality was moderate, and effect sizes showed large between-study heterogeneity. Hysterectomy was not associated with significant change in overall sexual function irrespective of surgical route, with patients tending to report potentially remaining sexual dysfunction posthysterectomy. Cervix removal was not significantly associated with differences in magnitude of change. Hysterectomy without BSO was associated with significantly stronger improvement in lubrication and orgasm than hysterectomy with BSO, which was not the case for desire, arousal or overall sexual function. However, these significant differences were not replicated within studies that directly compared cases with and without BSO.

CLINICAL IMPLICATIONS

Clinicians should address remaining sexual dysfunction posthysterectomy, and BSO should not be considered if not medically required.

STRENGTHS AND LIMITATIONS

We analyzed a comprehensive number of trials and studied clinically relevant factors that might relate to differences in change in sexual function. Conclusions need to be interpreted with caution since many studies showed moderate methodological quality and large effect size heterogeneity.

CONCLUSION

Subtotal and total hysterectomy was not associated with significant change in overall sexual function irrespective of surgical route, with patients tending to report potentially remaining sexual dysfunction posthysterectomy. Hysterectomy without BSO was associated with significantly stronger improvement in lubrication and orgasm than hysterectomy with BSO. Future research on hysterectomy should analyze predictors of sexual function change trajectories, such as different indications.

Somatotopic Mapping of the Developing Sensorimotor Cortex in the Preterm Human Brain

In the mature mammalian brain, the primary somatosensory and motor cortices are known to be spatially organized such that neural activity relating to specific body parts can be somatopically mapped onto an anatomical "homunculus". This organization creates an internal body representation which is fundamental for precise motor control, spatial awareness and social interaction. Although it is unknown when this organization develops in humans, animal studies suggest that it may emerge even before the time of normal birth. We therefore characterized the somatotopic organization of the primary sensorimotor cortices using functional MRI and a set of custom-made robotic tools in 35 healthy preterm infants aged from 31 + 6 to 36 + 3 weeks postmenstrual age. Functional responses induced by somatosensory stimulation of the wrists, ankles, and mouth had a distinct spatial organization as seen in the characteristic mature homunculus map. In comparison to the ankle, activation related to wrist stimulation was significantly larger and more commonly involved additional areas including the supplementary motor area and ipsilateral sensorimotor cortex. These results are in keeping with early intrinsic determination of a somatotopic map within the primary sensorimotor cortices. This may explain why acquired brain injury in this region during the preterm period cannot be compensated for by cortical reorganization and therefore can lead to long-lasting motor and sensory impairment.

Injury toll following the 1997 Maccabiah Games bridge collapse: implications of major disasters for sports medicine teams

A major disaster was encountered at the 1997 Maccabiah Games in Israel. As the Australian team was about to enter the main stadium for the opening ceremony, a pedestrian bridge they were crossing collapsed, killing 4 athletes and injuring many others. The aim of this paper is to establish the rates, types and anatomical locations of musculoskeletal injuries incurred by members of the Australian Maccabiah Games team, with particular reference to the impact of the bridge collapse. In total, the 410 members of the team (360 athletes and coaches and 50 team officials) reported 166 injuries from their participation in sport and 30 musculoskeletal injuries associated with the collapse of the bridge. The most common sports-related injuries were sprains and strains to the hip/thigh, lumbar spine and ankle/foot regions, while the bridge collapse resulted in, most commonly, sprains and contusions to the hip/thigh, knee, lower leg and ankle/foot regions. In addition, team members incurred many medical and psychological conditions. This paper makes several recommendations for sports medicine staff based on the experience of this significant sport disaster.

Medical issues relating to the Sydney Olympic Games

The Sydney Olympic Games in 2000 represent a significant medical and sporting challenge. Prior planning is the key to optimal performance, and team medical staff should be familiar with major medical and injury concerns of athletes and officials well prior to departure. A comprehensive team medical kit should be organised. Travel will be over great distances for many teams, so particular attention to optimising sleep and hydration is essential. The Olympic village experience can be overwhelming for some athletes, and medical staff should provide informed advice on food, transport and safety issues. Heat is less likely to be an issue than at recent summer Olympic Games, but should not be ignored completely. Major incidents can occur at any major sporting festival, and team medical staff should be appropriately prepared for these. All team medical staff should be aware of the current list of banned substances, and seek to minimise drug use by their athletes. After the event, an appropriate debriefing session should be held with a view to planning improvements for the future.
