RESUMEN
INTRODUCTION: Resistance training may be an effective intervention to improve menopausal symptoms and increase women's quality of life. However, most postmenopausal women do not perform regular resistance training. The purpose of this study was to explore postmenopausal women's experiences of participation in a resistance-training intervention to find barriers and motivators for the training. METHODS: Fifteen postmenopausal women with low physical activity, who participated in a randomized controlled trial evaluating the effect of a resistance-training program on vasomotor symptoms and health-related outcomes, were consecutively recruited to this qualitative study. After completion of the 15-week resistance-training program, they took part in individual semi-structured interviews, followed by a telephone interview 1 year later. All interviews were transcribed verbatim and thematic analysis was used to analyse the data. RESULTS: The analysis generated three themes that were involved at different time points. These were: "Trigger-Hopes of symptom relief", "An evolving motivation as a driving force for change" and "Finding new triggers". Accountability, and continuous professional and emotional support, were factors that fueled the women's motivation to perform regular resistance training during the study. Resistance training improved general well-being and most women experienced improvement in vasomotor symptoms. The women's motivation changed from being driven by a wish to improve bothersome symptoms, into a wish to achieve feelings of well-being and enjoyment. The change was seen regardless of effects of the intervention on vasomotor symptoms. CONCLUSION: This first qualitative evaluation of physical exercise as an intervention to treat vasomotor symptoms in postmenopausal women, found that the symptoms acted as a motivational trigger to initiate resistance training in low-active women. The motivation to exercise changed during the intervention from a wish to ameliorate symptoms into something the women did for enjoyment and well-being in general. This change in motivating factors may have contributed to a behavior change since all participants had increased their physical activity after 1 year regardless of effects on VMS. Trial registration The trial was preregistered at ClinicalTrials.gov; www. CLINICALTRIALS: gov , ID: NCT01987778 , date of first registration: 19/11/2013.

There is a well-known gap between what we know and what we do within healthcare service processes. Models that facilitate quality improvement (QI) have seen used to eliminate these gaps. Knowledge and competence in QI work are necessary for every professional within the healthcare system and are ideally learned through interprofessional collaboration and introduced during undergraduate studies. To meet these competence needs, Linköping University, Sweden, in collaboration with the main healthcare provider in the region, implemented a 2-week interprofessional QI learning module, which is mandatory for all undergraduate healthcare students. Ideas for practice-based QI projects were introduced to all the students who studied theory in the relevant domains of QI while working on these projects. A content analysis of students' written reports was conducted to investigate the focus of the projects. The analysis showed that most projects (65%) concerned staff-related issues, while 35% had patient perspectives. This distribution changed over time, increasing the number of patient centered projects.

RESEARCH QUESTION: Are low birth weight, prematurity, being born small for gestational age, or both, associated with a higher risk of male factor infertility in adulthood? DESIGN: Retrospective study of a clinical sample of 892 men, diagnosed with an infertility factor (male, female, combined or unexplained) together with their female partner at a University Hospital clinic in Sweden between 2005 and 2010. Data on birth weight and gestational age at birth were retrieved from the Swedish Medical Birth Register. The distribution of non-optimal birth characteristics in relation to infertility factor was described. A control group was created consisting of two men for each index man, born in Sweden in the same year as each index men, as well as a reference group consisting of all men born in Sweden the same years. RESULTS: The likelihood of having been born small for gestational age was almost fivefold higher in men with male factor infertility than in men with unexplained infertility (OR 4.84, 95% CI 1.32 to 17.80). Men with male factor infertility were more often born with non-optimal birth characteristics than the control group (14.8% versus 8.5%; Pâ¯=â¯0.010) and the reference group (14.8% versus 11.4%; P < 0.001). Men with azoospermia were more often born with non-optimal birth characteristics, compared with men without azoospermia (21.3% versus 12.1%; Pâ¯=â¯0.038). CONCLUSIONS: The results suggest an association between intrauterine growth restriction and male factor infertility in adulthood.

AIM: To assess mental health outcomes of very low birthweight (VLBW, <1500 g) subjects to adulthood and to examine salivary cortisol and hair cortisol levels and their relation to birth characteristics and mental health. METHODS: A Swedish regional cohort of 56 VLBW subjects and 55 full-term controls were assessed at the ages 27-28 with adult self-reported scales and the mean of 2 days diurnal salivary cortisol and hair cortisol. The cohorts had been assessed at 15 years of age with youth self-reported scales. RESULTS: There were no differences between the groups in youth self-reported scales and adult self-reported scores. The 24 participating VLBW girls scored lower on youth self-reported scales externalising and total problem scores than the control girls. In adulthood, the 21 participating VLBW women had significantly higher morning concentrations of salivary cortisol than control women, P = .014. No significant associations were found between cortisol concentrations and adult self-reported scales internalising, externalising and total scores. CONCLUSION: Self-reported mental health in VLBW subjects was comparable with normal birthweight controls indicating a satisfying transition from adolescence to adulthood. VLBW females had higher morning salivary cortisol concentrations, suggesting a gender difference. We found no correlations between cortisol and mental health.

Objective: To increase the understanding of women who experience negative effects on sexual function when using hormonal contraception.Methods: We performed 24 in-depth interviews with women who had previously experienced negative sexual function effects while using hormonal contraceptives. The thematic analysis method was used.Results: 'After experience comes insight', 'Lubrication and desire go hand in hand', 'Mental wellbeing comes before desire' and 'The contraceptive counsellor potentially facilitates insight and decision-making' were the main themes found in the study.Conclusions: This selected group of women described lubrication difficulties and decreased sexual desire associated with both contraceptive use and the menstrual cycle. Contraceptive use became easier with age and with better understanding. The contraceptive counsellor could facilitate the process. Further choice between hormonal or non-hormonal contraceptive methods depended primarily on experienced adverse effects on mood, and secondarily on sexual function, weighed against the advantages or disadvantages experienced during the person's own menstrual cycle.

BACKGROUND: Individuals born very preterm or with very low birth weight (VLBW) have a reduced likelihood to reproduce according to population-based register studies. Extremely low-birth weight born adults had a lower reproduction rate for both men and women in a follow-up study. AIM: To investigate if being born with VLBW is associated with differences in the reproductive health, i.e. age of menarche, menstrual cycle pattern, pregnancy rates and hormone profile compared with women born at term. METHODS: A prospective long-term follow-up of a cohort of live-born VLBW children and their controls studied repeatedly since birth and now assessed at 26-28 years of age. Of the totally 80 girls enrolled from birth 49 women (24 VLBW women and 25 controls) participated in the current follow-up. The women's anthropometric data and serum hormone levels were analysed. RESULTS: The reproductive hormone levels, including Anti-Mullerian Hormone, did not differ significantly between VLBW women and their controls. Both groups reported menstrual cycle irregularities and pregnancies to the same extent but the VLBW women reported 1.5 years later age of menarche. The VLBW subjects had a catch-up growth within 18 months of birth but remained on average 5 cm shorter in adult height. There were no significant differences in BMI, sagittal abdominal diameter, blood pressure or in their answers regarding life style between the VLBW women and the controls. CONCLUSION: No differences in the reproductive hormone levels were found between VLBW women and their controls. Although age at menarche was somewhat higher in the VLBW group menstrual cycles and pregnancy rates were similar in the VLBW and control groups. Further follow-up studies are required to elucidate the health outcomes of being born VLBW.

Men affected with idiopathic infertility often display basic spermiogramme values similar to fertile individuals, questioning the diagnostic impact of the World Health Organization (WHO) thresholds used. This study explored sperm DNA fragmentation in single ejaculates from 14 fertile donors and 42 patients with idiopathic infertility providing semen for assisted reproductive techniques in a university fertility clinic. Each ejaculate was simultaneously studied for sperm DNA fragmentation by the flow cytometer-based sperm chromatin structure analysis (SCSA) and the new light-microscopy-based sperm chromatin dispersion assay (SCD-HaloSpermG2® ), before and after sperm selection for in vitro fertilisation with a colloid discontinuous gradient. The WHO semen variables did not differ between groups, but DNA fragmentation after SCSA (DFI) or SCD (SDF) was significantly (p < 0.05) higher in patients (DFI: 40.2% ± 3.0 vs. SDF: 40.3% ± 1.4) than in fertile donors (DFI: 17.1% ± 2.1 vs. SDF: 20.9% ± 2.5). Sperm selection led to lower proportions of DNA-fragmented spermatozoa (DFI: 11.9 ± 1.7 vs. SCD: 10.0 ± 0.9, p < 0.05). The techniques output correlated highly and significantly (r2 = 0.82). DNA fragmentation is confirmed as a relevant variable for scrutinising patients with idiopathic infertility, beyond the evidently insufficient WHO semen analyses. Since both techniques yielded similar results, the reduced necessity of complex equipment when running SCD ought to be considered for a clinical setting.

BACKGROUND: The current estimates of the prevalence of primary ovarian insufficiency (POI) are very variable, but are in most studies believed to be around 1%. It is also very likely tat the prevalence of POI differs between countries and over time. We therefore aimed to assess the prevalence of primary ovarian insufficiency in Sweden. METHODS: All 1,036,918 women born between 1973 and 1993 in Sweden were included. The prevalence of POI was based on data from the Swedish Patient Register through the diagnosis code or through the Prescribed Drug Register. The number of women below 40 years of age diagnosed with the ICD-10 diagnoses E28.3 or E89.4, and women who had been dispensed drugs for treatment of climacteric symptoms were included. RESULTS: Out of the 1,036,918 women, 19,253 (1.9%) had POI. The prevalence of spontaneous POI was 1.7% and the prevalence of iatrogenic POI was 0.2%. Most women (98.8%) with POI were identified from the Prescribed Drug Register; only 4.1% were found in the Patient Register, whereas 2.9% were identified in both registers. CONCLUSIONS: The total prevalence of POI was 1.9%, 95% CI: 1.7-2.1, indicating a higher prevalence than often previously reported.

Interprofessional collaboration involves some kind of knowledge sharing, which is essential and will be important in the future in regard to the opportunities and challenges in practices for delivering safe and effective health care. Nursing assistants are seldom mentioned as a group of health care workers that contribute to interprofessional collaboration in health care practice. The aim of this ethnographic study was to explore how the nursing assistants' knowledge can be shared in a team on a spinal cord injury rehabilitation ward. Using a sociomaterial perspective on practice, we captured different aspects of interprofessional collaboration in health care. The findings reveal how knowledge was shared between professionals, depending on different kinds of practice architecture. These specific cultural-discursive, material-economic, and social-political arrangements enabled possibilities through which nursing assistants' knowledge informed other practices, and others' knowledge informed the practice of nursing assistants. By studying what health care professionals actually do and say in practice, we found that the nursing assistants could make a valuable contribution of knowledge to the team.

STUDY QUESTION: Is the risk of postpartum psychosis (PPP) increased in women who give birth after IVF treatment compared to after spontaneous conception? SUMMARY ANSWER: The risk of PPP is not higher in the group of women who give birth after IVF treatment compared with women who give birth after spontaneous conception. WHAT IS KNOWN ALREADY: Women who conceive using IVF treatment can experience higher levels of pregnancy-specific distress and are at increased risk of pre-eclampsia, an immune-related condition which in turn has been linked to PPP, as well as other pregnancy and delivery complications, which also serve as PPP risk factors. It is not known whether the risk of PPP is increased in women who have conceived using IVF treatment. STUDY DESIGN, SIZE, DURATION: A nationwide, register-based, case-control study of all primiparous women who had given birth after IVF treatment between 1988 and 2012. PARTICIPANTS/MATERIALS, SETTING, METHODS: Information about 10 412 women was collected from the Swedish IVF register. A control group of women who had given birth after spontaneous conception was selected from the Swedish Medical Birth Register (n = 18 624). PPP diagnoses, identified using ICD-10 diagnostic codes F20-31 and F531 the first year postpartum, were collected from the National Patient Register. Associations between PPP and IVF/spontaneous conception were evaluated using chi-square tests and logistic regression analyses while controlling for known risk factors of PPP. MAIN RESULTS AND THE ROLE OF CHANCE: There were no differences in PPP prevalence between the IVF group and the control group (0.3%, n = 29 versus 0.4%, n = 77) in the chi-square analysis (P = 0.169) or the multiple logistic regression analyses (P = 0.646; odds ratio (OR): 1.178; 95% CI: 586-2.365). No associations between pregnancy or delivery complications and PPP were found. A history of any psychiatric disorder (P < 0.001; OR = 40.7; 95% CI = 23.9-69.5), or specifically a psychotic (P < 0.001; OR = 324.1; 95% CI = 131.3-800.0), bipolar (P < 0.001; OR = 516.1; 95% CI = 264.3-1008.1), depressive (P < 0.001; OR = 27.5; 95% CI = 16.2-46.5), anxiety (P < 0.001; OR = 12.9; 95% CI = 7.4-22.6) or personality disorder (P < 0.001; OR = 27.3; CI = 11.8-63.0), all significantly increased the risk of PPP. LIMITATIONS REASONS FOR CAUTION: PPP is a rare condition, hence the number of individuals was small. Since all women for whom information was available from all registers were included, it was not possible to further increase the power of the study using this design. WIDER IMPLICATIONS OF THE FINDINGS: Since this study is the first to examine risk of PPP after IVF treatment, more studies are needed to verify these results. The generalizability is restricted to primiparous women in western countries. This study confirms the results of previous studies in showing a history of mental illness to be the major risk factor for PPP. STUDY FUNDING/COMPETING INTERESTS: None. TRIAL REGISTRATION NUMBER: Not applicable.

OBJECTIVES: The aim of the study was to determine whether a decrease in sexual desire is more prevalent among women using hormonal contraception than among women using hormone-free contraception, and whether a decrease increases the risk of changing to another contraceptive method. METHODS: A validated questionnaire was posted to 3740 women (aged 22, 25 or 28 years) living in Sweden. Descriptive statistics were used to present the results; differences between groups were tested using χ(2) analyses. A multiple logistic regression model was used for analysis of possible confounders. RESULTS: The response rate was 50%. The majority (81%) of respondents used some kind of contraception, and 88% were generally satisfied with the method used. Regardless of the type of method, 27% of hormonal contraceptive users reported a decrease in sexual desire that they attributed to their use of hormonal contraception, whereas only 12% of women using hormone-free contraception reported a decrease in sexual desire (p<0.01). This twofold risk of a decrease in sexual desire was shown in the multiple regression analysis to be independent of age group, depression, BMI, educational level and parity. However, having a partner was found to be a factor of equal importance: women with partners experienced reduced desire twice as often as women without partners. The observed odds ratio for planning to stop hormonal contraception or to change to a different type due to reduced desire was 8.16 (95% confidence interval 6.65-10.1) among women who had had the same experience during a previous period of hormonal contraceptive use. CONCLUSIONS: Women using hormonal contraception were more likely to experience reduced sexual desire compared with women using hormone-free contraception. Experiencing reduced desire was a strong predictive factor for women to change contraceptive method.

Studies on graduates' transitions from education into clinical work highlight inequalities concerning how women and men experience their professional learning and development. This study explores how female and male students from different programs within the health care education system (i.e. medicine, nursing, occupational therapy, and physiotherapy programmes) experience an interprofessional training ward (IPTW) as a part of their professional identity formation. Students from the medicine, nursing, physiotherapy, and occupational therapy programmes collaborate in teams during two weeks at one of three IPTWs at the medical school, Linköping University. They together take the responsibility for diagnosis, treatment, and rehabilitation of the patients, albeit with professional supervisors as support. During 2010 to 2011, 454 (93%) of the 488 students who practiced at the IPTWs answered a questionnaire on their experiences of the IPTW. The students stated that the IPTW had positively influenced their professional development. The female and male medical students were significantly less positive than other female and male students, respectively, concerning the value of IPTW. The male students from all programmes were slightly, but significantly, less positive than all the female students. These findings show that students "do gender" as an integral part of the educational practice. It is important to scrutinise the IPTW as an educational practice, influencing students' preparation for future work. Gender should be discussed not only during the IPTW rotation but also in general during the curriculum for all healthcare programmes.

PURPOSE: Acupuncture has been suggested as therapy for hot flashes in women with breast cancer and men with prostate cancer. In this systematic review, we sought to evaluate the long-term effects on vasomotor symptoms after the end of a defined treatment period of acupuncture in women with breast cancer and men with prostate cancer. METHODS: A literature search revealed 222 articles within the field. With defined exclusion criteria, we identified 17 studies. We also used the Jadad quality score and identified seven studies with a score of at least 3. RESULTS: Six of seven identified studies qualified for inclusion in an analysis that measured frequency of hot flashes weighted in relation to number of patients (n=172). The average reduction from baseline to end of acupuncture (ranging between 5 and 12 weeks of treatment) showed 43.2 % reduction of hot flashes. At the last follow-up (mean 5.8 months, range 3-9 months) after the end of therapy, the weighted reduction from baseline was sustained at 45.6 % in the 153 of 172 patients (89 %) who were followed up. CONCLUSIONS: Data from six prospective analyzed studies indicate at least 3-month effects after the end of acupuncture treatment for flashes in women with breast cancer and men with prostate cancer. However, larger randomized trials with long-term follow-up will be needed to confirm these preliminary findings.

Interprofessional training wards (IPTWs), aiming to enhance interprofessional collaboration, have been implemented in medical education and evaluated over the last decade. The Faculty of Health Sciences, Linköping University has, in collaboration with the local health provider, arranged such training wards since 1996, involving students from the medical, nursing, physiotherapy, and occupational therapy programs. Working together across professional boundaries is seen as a necessity in the future to achieve sustainable and safe healthcare. Therefore, educators need to arrange learning contexts which enhance students' interprofessional learning. This article shows aspects of how the arrangement of an IPTW can influence the students' collaboration and learning. Data from open-ended questions from a questionnaire survey, during autumn term 2010 and spring term 2011 at an IPTW, was analyzed qualitatively using a theoretical framework of practice theory. The theoretical lens gave a picture of how architectures of the IPTW create a clash between the "expected" professional responsibilities and the "unexpected" responsibilities of caring work. Also revealed was how the proximity between students opens up contexts for negotiations and boundary work. The value of using a theoretical framework of professional learning in practice within the frames of healthcare education is discussed.

OBJECTIVE: To investigate if abdominal adipose tissue volumes and ratios change after a 15-week structured resistance training intervention in postmenopausal women with vasomotor symptoms (VMS). STUDY DESIGN: Sixty-five postmenopausal women with VMS and low physical activity were randomized to either three days/week supervised resistance training or unchanged physical activity for 15 weeks. Women underwent clinical anthropometric measurements and magnetic resonance imaging (MRI) at baseline and after 15 weeks. MRI was done using a Philips Ingenia 3.0 T MR scanner (Philips, Best, The Netherlands). The per protocol principle was used in the analysis of data. MAIN OUTCOME MEASUREMENTS: The absolute change from baseline to week 15 in visceral adipose tissue (VAT) volume and the relative ratio (VAT ratio) between VAT and total abdominal adipose tissue (TAAT), i.e. the sum of abdominal subcutaneous adipose tissue (ASAT) and VAT. RESULTS: There were no significant differences between the groups in characteristics, anthropometry or MRI measures at baseline. Women who were compliant with the intervention (i.e. participated in at least two of the three scheduled training sessions per week) had significantly different reduction over time in ASAT (p = 0.006), VAT (p = 0.002), TAAT (p = 0.003) and fat ratio (p < 0.001) compared with women in the control group. CONCLUSIONS: Implementation of a 15-week resistance training regimen in midlife may help women to counteract the abdominal fat redistribution associated with the menopausal transition.

UNLABELLED: Symptoms of testosterone deficiency and concentrations of testosterone (T) and bioavailable testosterone (BT) were studied in 35- and 45-year-old men. METHODS: A questionnaire, was sent to all 35- and 45-year-old men in Linköping, Sweden (n=1998). The questionnaire has earlier been used for 55- to 75-year-old men and included demographic data, medical history, different symptoms possibly of T deficiency and the 10 questions from the "ADAM-questionnaire". Totally 200 men randomly selected among the men who answered the questionnaire were asked to give blood samples for analysis of T- and BT-concentrations. RESULTS: A total of 38.7% of the questionnaires were returned and analysed, and 43.5% of the 200 randomly selected men gave blood samples. The older age group reported more symptoms that may be connected to low B and BT and had lower T- and BT-concentrations. Less strong erections and higher alcohol consumption were associated with lower concentrations of BT in 45-year-old men. CONCLUSIONS: The burden of symptoms possibly related to low T concentrations were higher in 45-year-old men, and BT and T were lower. However, due to the low answer frequency and number of blood samples analyzed no general conclusions can be drawn.

BACKGROUND: Age related bone loss is widely accepted as related to decreased serum levels of circulating sex hormones. Epidemiological data also show distal radius fractures in men to be a sensitive marker of bone fragility. The aim of this study was to assess if men with a history of distal radius fracture have lower bone mass density (BMD), lower free androgen index (FAI), lower total testosterone (T) and lower bio-available testosterone (Bio-T) than healthy age-matched controls. PATIENTS AND METHODS: A case-control study is based on consecutive cases treated for low energy distal radius fracture at our department and age-matched controls. Thirty-nine men treated between 1997-2004 and 45 age-matched controls underwent calcaneal bone density measurements (t-score) and analyses of T, Bio-T and serum hormone binding globulin (SHBG). RESULTS: The fracture group had lower BMD (p < 0.01) and lower FAI (p = 0.01). Linear regression analysis showed a correlation between Bio-T and t-scores (p = 0.03). Using analysis of covariance, a significant difference with lower Bio-T in the fracture group was shown. CONCLUSION: Bio-T seems to correlate with BMD in elderly men and may serve as a marker for increased fracture risk in this patient group.

PURPOSE: Evaluate effects of electro-acupuncture (EA) and hormone therapy (HT) on health-related quality-of-life (HRQoL) and sleep in breast cancer survivors with vasomotor symptoms. METHODS: Forty-five women, randomized to EA (n = 27) for 12 weeks or HT (n = 18) for 24 months, were followed for up to 2 years. Distress caused by, and numbers of, hot flushes, hours slept and times woken up/night, Psychological and General Well-being Index (PGWB) and Women's Health Questionnaire (WHQ) were registered before and during treatment and at 6, 9, 12, 18 and 24 months after start of treatment. RESULTS: After 12 weeks of EA (n = 19), WHQ improved from 0.32 (IQR 0.23-0.53) at baseline to 0.24 (IQR 0.12-0.39; p < 0.001) and PGWB from 78 (IQR 53-89) to 79 (IQR 68-93; p = 0.002). All sleep parameters improved and Hot Flush Score (HFS) decreased by 80%. At 12 months, WHQ, PGWB and all sleep parameters remained significantly improved (n = 14) and HFS decreased by 65%. After 12 weeks of HT (n = 18), WHQ improved from 0.29 (IQR 0.15-0.44) at baseline to 0.15 (IQR 0.05-0.22; p = 0.001), PGWB from 75 (IQR 59-88) to 90 (62-97; p = 0.102) and three of five sleep parameters improved. CONCLUSION: Both EA and HT increased HRQoL and sleep, probably through decreasing numbers of and distress by hot flushes. Although flushes decreased less in the EA group than in the HT group, HRQoL improved at least to the same extent maybe due to other effects of EA, not induced by HT, e.g. on anxiety, vitality and sleep, supported by subscale analyses. EA should be further evaluated as treatment for women with breast cancer and climacteric complaints, since HT no longer can be recommended for these women.

Calcitonin gene-related peptide (CGRP) seems to be involved in hot flushes in women and in castrated men. Therefore, we studied whether the plasma concentrations of CGRP changed during flushes in a group of healthy aging men. Twelve men (49-71 years) with no history of current or former prostate cancer or hormonal treatment reporting ≥ 20 flushes/week were investigated. Blood samples were drawn during and between flushes for analysis of CGRP and also androgen concentrations, that is, testosterone and bioavailable testosterone were analysed. Skin temperature and skin conductance were monitored. Thirty-five flushes were reported by 10 men. The plasma concentrations of CGRP did not increase during flushes. No significant change in skin temperature or conductance was found. CGRP is probably not involved in the mechanisms of flushes in healthy aging men. Therefore, flushes in aging healthy men seem to be different from flushes in men and women deprived of sex steroids where CGRP increases during flushes.

The mechanisms behind hot flashes in menopausal women are not fully understood. The flashes in women are probably preceded by and actually initiated by a sudden downward shift in the set point for the core body temperature in the thermoregulatory center that is affected by sex steroids, ß-endorphins, and other central neurotransmitters. Treatments that influence these factors may be expected to reduce hot flashes. Since therapy with sex steroids for hot flashes has appeared to cause a number of side effects and risks and women with hot flashes and breast cancer as well as men with prostate cancer and hot flashes are prevented from sex steroid therapy there is a great need for alternative therapies. Acupuncture affecting the opioid system has been suggested as an alternative treatment option for hot flashes in menopausal women and castrated men. The heat loss during hot flashes may be mediated by the potent vasodilator and sweat gland activator calcitonin gene-related peptide (CGRP) the concentration of which increases in plasma during flashes in menopausal women and, according to one study, in castrated men with flushes. There is also evidence for connections between the opioid system and the release of CGRP. In this paper we discuss acupuncture as a treatment alternative for hot flashes and the role of CGRP in this context.
