Abstract
The aim of this study was to investigate the effect of different extenders on the post-thaw (PT) quality of sperm originating from the sperm-rich fraction (SRF) and post-sperm-rich fraction (PSRF) of boar ejaculate. Motility and velocity parameters, analyzed using a computer-assisted semen analysis (CASA) system, and membrane integrity parameters were markedly higher in frozen-thawed (FT) spermatozoa of the SRF in both the Belstville Thawing Solution (BTS) and Androhep Plus (AHP) extenders, irrespective of the post-thaw (PT) storage time. Furthermore, reduced cryo-survival was more marked in FT spermatozoa of the PSRF in both extenders following storage for 60 min. It was found that the SRF-stored samples in the AHP extender for 60 min exhibited significantly higher percentages of spermatozoa with total motility, mitochondrial function and acrosome integrity than those stored in the BTS extender. The findings of this study confirm that components of the ejaculate fractions and extender have varying effects on the cryo-survival of boar spermatozoa.

Abstract
INTRODUCTION The rate of community antibiotic use is high in Aotearoa New Zealand (NZ) when compared to other nations, and in NZ, as in most other nations, antibiotics are very commonly prescribed for self-limiting upper respiratory tract infections (URTIs). Resources that build knowledge, perceptions and understanding can potentially reduce unnecessary antibiotic consumption. METHODS To inform the content of educational resources, we conducted an in-depth qualitative study with 47 participants via 6 focus groups of the knowledge, attitudes, and expectations of whānau Māori and Pacific peoples about antibiotics and URTIs. RESULTS Focus groups with 47 participants identified four themes: Knowledge that might influence expectations to receive antibiotics for URTIs; Perceptions - the factors that influence when and why to seek medical care for URTI; Expectations - the features of successful medical care for URTI; Solutions - how to build community knowledge about URTI and their treatment and prevention. Knowledge that might reduce expectations to receive antibiotics for URTI included confidence in the use of alternative remedies, knowledge that URTI are usually caused by viruses, and concerns about antibiotic adverse effects. Participants commonly reported that they would confidently accept their doctor's recommendation that an antibiotic was not necessary for an URTI, provided that a thorough assessment had been performed and that treatment decisions were clearly communicated. CONCLUSION These findings suggest that building patients' knowledge and skills about when antibiotics are necessary, and increasing doctors' confidence and willingness not to prescribe an antibiotic for patients with an URTI, could significantly reduce inappropriate antibiotic prescribing in NZ.

Abstract
Seminal plasma (SP) proteins are responsible for sperm functional quality. Developing a reliable method to determine the degree of oxidative damage of these proteins is important for establishing semen fertilizing ability. The main aim of the study was to verify the applicability of protein carbonyl derivatives measurement in the SP of canine and stallion, using a method with 2,4-dinitrophenylhydrazine (DNPH). The research material consisted of ejaculates obtained from eight English Springer Spaniels, and from seven half-blood stallions during the breeding and non-breeding season. The content of carbonyl groups in the SP was measured on the basis of the reactions with DNPH. The following reagent variants were used to dissolve protein precipitates: Variant 1 (V1) - 6M Guanidine solution and Variant 2 (V2) - 0.1M NaOH solution. It has been shown that to obtain reliable results for the measurement of protein carbonylated groups in the dog and horse SP, both 6M Guanidine and 0.1M NaOH may be used. A correlation was also found between the number of carbonyl groups and the total protein content in the canine (V1: r = -0.724; V2: r = -0.847) and stallion (V1: r = -0.336; V2: r = -0.334) SP. Additionally, the study showed a higher content (p≤0.05) of protein carbonyl groups in the stallion SP in the non-breeding season compared to the breeding season. The method based on the reaction with DNPH, due to its simplicity and cost effectiveness, appears to be suitable for large-scale application in the determination of the SP proteins oxidative damage in dog and horse semen.

Abstract
Background: Transgender healthcare is a rapidly evolving interdisciplinary field. In the last decade, there has been an unprecedented increase in the number and visibility of transgender and gender diverse (TGD) people seeking support and gender-affirming medical treatment in parallel with a significant rise in the scientific literature in this area. The World Professional Association for Transgender Health (WPATH) is an international, multidisciplinary, professional association whose mission is to promote evidence-based care, education, research, public policy, and respect in transgender health. One of the main functions of WPATH is to promote the highest standards of health care for TGD people through the Standards of Care (SOC). The SOC was initially developed in 1979 and the last version (SOC-7) was published in 2012. In view of the increasing scientific evidence, WPATH commissioned a new version of the Standards of Care, the SOC-8. Aim: The overall goal of SOC-8 is to provide health care professionals (HCPs) with clinical guidance to assist TGD people in accessing safe and effective pathways to achieving lasting personal comfort with their gendered selves with the aim of optimizing their overall physical health, psychological well-being, and self-fulfillment. Methods: The SOC-8 is based on the best available science and expert professional consensus in transgender health. International professionals and stakeholders were selected to serve on the SOC-8 committee. Recommendation statements were developed based on data derived from independent systematic literature reviews, where available, background reviews and expert opinions. Grading of recommendations was based on the available evidence supporting interventions, a discussion of risks and harms, as well as the feasibility and acceptability within different contexts and country settings. Results: A total of 18 chapters were developed as part of the SOC-8. They contain recommendations for health care professionals who provide care and treatment for TGD people. Each of the recommendations is followed by explanatory text with relevant references. General areas related to transgender health are covered in the chapters Terminology, Global Applicability, Population Estimates, and Education. The chapters developed for the diverse population of TGD people include Assessment of Adults, Adolescents, Children, Nonbinary, Eunuchs, and Intersex Individuals, and people living in Institutional Environments. Finally, the chapters related to gender-affirming treatment are Hormone Therapy, Surgery and Postoperative Care, Voice and Communication, Primary Care, Reproductive Health, Sexual Health, and Mental Health. Conclusions: The SOC-8 guidelines are intended to be flexible to meet the diverse health care needs of TGD people globally. While adaptable, they offer standards for promoting optimal health care and guidance for the treatment of people experiencing gender incongruence. As in all previous versions of the SOC, the criteria set forth in this document for gender-affirming medical interventions are clinical guidelines; individual health care professionals and programs may modify these in consultation with the TGD person.

Overnight pulse oximetry (OPO) is often used to support the diagnosis of obstructive sleep apnoea (OSA) and stratify risk of peri-operative breathing difficulties in children undergoing adenotonsillectomy for OSA. Our objective was to audit our indications for OPO and the impact on subsequent ENT management. We sought to assess the correlation of STBUR (Snoring, Troubled-breathing, Unrefreshed Questionnaire) score with OPO values in these patients.
Method
Retrospective review of 32 OPO reports over a 7-month period. Data collected included age, weight, indication, mean spO2, number of dips >4%, outcome and STBUR score.
Results
The commonest indication (19) for OPO was to assess severity of OSA in children <3 or those with significant comorbidity to determine best setting for surgery; 50% were ultimately managed in a tertiary centre. 10 children underwent OPO due to diagnostic uncertainty but significant parental concern; all studies normal and parents reassured. STBUR score correlated poorly with number of dips >4% (R = 0.0109) and mean nadir >4% (R = 0.0031) Weight poorly recorded (19%).
Conclusions
Referrals were generally appropriate and influenced management in all cases. STBUR scores insufficiently sensitive to stratify severity of OSA. New protocol developed.

Abstract
Electrophoretic methods were used to identify protein complexes formed between ostrich egg yolk lipoprotein fractions (LPFo) with seminal plasma (SP) of fractionated ejaculates, and to investigate the effect of these complexes on boar semen quality after cryopreservation. Chromatographic SP fractions (F1, F2 and F3), with or without LPFo solution, were subjected to sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) analysis. Comparative electrophoretic analyses of the SP revealed marked differences in the SDS-PAGE protein profiles among boars. Electrophoretic analyses showed that the interactions of LPFo with SP resulted in the appearance of high-intensity protein bands. Spermatozoa were exposed to SP chromatographic fractions originating from F1, F2 and F3, and the whole SP (wSP) before being frozen. Spermatozoa exposed to F1 and F2 exhibited significantly higher post-thaw motility compared to those treated with either F3 or wSP. In most of the boars the proportions of membrane- -intact frozen-thawed spermatozoa differed among the treatments, being significantly lower in the wSP-treated samples. The incidence of frozen-thawed spermatozoa with DNA fragmentation was less prevalent in samples exposed to F3 or the wSP. The results of this study confirmed that the interactions of LPFo with fractionated SP during the cooling period contributed to alterations in the sperm membranes, rendering them less susceptible to temperature-related injury.

Abstract
In our recent study we demonstrated that the holding of fresh semen in fractionated seminal plasma (SP1, >40 kDa; SP2, ⟨40 kDa), obtained by gel filtration chromatography, significantly improved the sperm quality characteristics following cryopreservation (Wasilewska-Sakowska et al. 2019). In this study we investigated the effect of post-thaw (PT) supplementation of fractionated SP (SP1 and SP2) on the survival of spermatozoa from boars with good and poor semen freezability, GSF and PSF, respectively. Two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) analysis showed distinct differences in the protein profiles of SP1 and SP2 from boars with GSF or PSF regarding the number of protein spots. Sperm motility characteristics and the motion patterns, assessed using the computer-assisted sperm analysis (CASA) system, were markedly higher in PT semen supplemented with SP1 and SP2 from boars with GSF. Post-thaw supplementation of either SP1 or SP2 from boars with GSF significantly improved mitochondrial function, plasma membrane and acrosome integrity, and viability during storage. The findings of this study have confirmed that the presence of protective protein components in varying abundance in either fractionated SP from boars with good freezability ejaculates significantly improved the sperm survival following PT storage.

Abstract
Semen freezability is associated with genetic markers, and there is a diverse set of sperm transcripts that have been attributed to various cellular functions. RNA-Seq was performed to compare the transcript profiles of spermatozoa from boars with different semen freezability. We examined ejaculates from the Polish large white (PLW) boars that were classified as having good and poor semen freezability (GSF and PSF, respectively; n = 3 boars per group) by assessing post-thaw motility characteristics, mitochondrial membrane potential, plasma membrane and acrosome integrity. Total RNA was isolated from fresh spermatozoa from boars of the GSF and PSF groups and subjected to RNA-Seq (Illumina NextSeq 500 platform). Transcript abundance was assessed with the DESeq2, DESeq, and EdgeR Bioconductor R packages, and varying numbers of differentially expressed gene (DEG) transcripts were detected in the spermatozoa of each boar. Using RNA-Seq, we identified several genes associated with inflammation and apoptosis (FOS, NFATC3, ITGAL, EAF2 and ZDHHC14), spermatogenesis (FGF-14 and BAMBI), autophagy (RAB33B), protein phosphorylation (PTPRU and PTPN2) and energy metabolism (ND6 and ACADM) that were predominantly up-regulated in poor freezability ejaculates. Quantitative reverse transcription polymerase chain reaction (RT-qPCR) validated the transcript expression levels detected by RNA-Seq and thus confirmed the reliability of this technique. Subsequent validation with western blotting showed that the expression of three proteins was in accordance with the transcript abundance. Overall, we demonstrated that the up-regulation of the DEG transcripts in spermatozoa was associated with poor semen freezability. We suggest that spermatozoa transcriptome profiling provides a foundation to further elucidate the relevance of sperm-related transcripts on cryo-survival. The sperm-related transcripts, namely FOS, NFATC3, EAF2, BAMBI, PTPRU, PTPN2, ND6 and ACADM, are potential markers for predicting the freezability of boar semen.

Abstract
The aim of this study was to identify the proteoforms of albumin and kallikrein in stallion seminal plasma (SP), and to determine their correlations with sperm motility parameters. The experimental material consisted of ejaculates from 8 stallions, which were collected during the breeding and non-breeding seasons (BS and NBS, respectively). SP proteins were identified by 2-D PAGE and mass spectrometry (MALDI TOT/TOF MS). Sperm motility parameters were analyzed using the CASA system. Protein expression (integrated optical density-IOD) of albumin proteoforms 1 (ALB 1) and 2 (ALB 2) and kallikrein proteoforms 1 (KAL 1) and 2 (KAL 2) was correlated (p⟨0.05) with sperm motility parameters (total motility and progressive motility) during the BS. No significant correlations were found between the expression of albumin or kallikrein and sperm motility parameters during the NBS. The presence of correlations between the expression of ALB 1, ALB 2, KAL 1, KAL 2 and selected sperm motility parameters could suggest that the analyzed components of the SP belong to the group of fertility-associated proteins (FAPs).

Abstract
In this study the quality of total RNA, isolated from fresh spermatozoa, was compared between boars with good and poor semen freezability (GSF and PSF, respectively). Semen from 3 boars with GSF exhibited significantly higher total motility, mitochondrial function, plasma membrane integrity and reduced lipid peroxidation compared with 3 boars with PSF after cryo- preservation. There were variations in the quality of RNA isolated from spermatozoa of boars with GSF and PSF. Boars with GSF exhibited mainly full-length, intact RNA, whereas substantial amounts of degraded RNA were detected in spermatozoa from boars with PSF. Further under- standing of the biological relevance of RNAs in sperm function is critical to improve the freezabil- ity of boar semen.

Abstract
Lipoproteins, isolated from ostrich egg yolk (LPFo), provide excellent protection for boar spermatozoa against cryo-induced damage. The present study was performed to investigate the effects of LPFo on the freezability and fertilizing capacity of frozen-thawed (FT) boar semen after post-cervical artificial inseminations (post-CAIs). Semen, collected from 7 Polish Large White (PLW) and 4 Polish Landrace (PLR), was frozen in an extender containing LPFo. Post-CAIs were performed in 38 multiparous sows, using a catheter-cannula kit. Sows were inseminated 2× within one oestrus, and fertility parameters were recorded after farrowing. Neither boar (within breed) nor breed affected the quality of the pre-freeze (PF) semen, such as total motility (TMOT), mitochondria membrane potential (MMP), plasma membrane integrity (PMI), osmotic resistance test (ORT) and DNA fragmentation. Differences in the freezability of boar semen were observed among the boars, whereas there were no marked breed effects. Post-thaw TMOT markedly declined over storage time in most of the boars, particularly at 60 min after thawing. Inseminations of post-weaned oestrus sows resulted in pregnancy and farrowing rates of 84.2% and 81.6%, respectively. Neither the mean number of piglets born (NB) nor the mean number of piglets born alive (NBA) was affected by boar or breed. The total number of piglets born was 365, resulting in 11.8 NB piglets, whereas the total number of piglets born alive was 353, with 11.4 NBA piglets per litter. The findings of this study reaffirm the variations in the freezability of boar semen. In this study the supplementation of ostrich egg yolk lipoproteins to the freezing extender of boar semen produced high proportions of functionally viable FT spermatozoa that were capable of providing acceptable fertility results after post-CAIs in multiparous sows.

Abstract
AIM Enhanced recovery after surgery (ERAS) programmes and laparoscopic techniques both provide short-term benefits to patients undergoing colorectal cancer surgery. ERAS protocol compliance may improve long-term survival in those undergoing open colorectal resection but as laparoscopic data has not been reported. Therefore, we aimed to investigate the impact of the combination of laparoscopy and ERAS management on 5-year overall survival. METHODS A dedicated prospectively populated colorectal cancer surgery database was reviewed. Patient inclusion criteria were biopsy-proven colorectal adenocarcinoma, undergoing elective surgery undertaken with curative intent. All patients were managed within an established ERAS programme and routinely followed up for 5 years. Overall survival was measured using the log-rank Kaplan-Meier method at 5 years. RESULTS Eight hundred fifty-four patients met the inclusion criteria. Four hundred eighty-one (56%) cases were laparoscopic with 98 patients (20%) requiring conversion. There were no differences in patient or tumour demographics between the surgical groups. Median ERAS protocol compliance was 93% (range 53-100%). Five-year overall survival was superior in laparoscopic cases compared with that of converted and open surgery (78 vs 68 vs 70%, respectively, p < 0.007). An open approach (HR 1.55, 95%CI 1.16-2.06, p = 0.002) and delayed hospital discharge (> 7 days, HR 1.5, 95%CI 1.13-1.9, p = 0.003) were the only modifiable risk factors associated with poor survival. CONCLUSIONS The use of a laparoscopic approach with enhanced recovery after surgery management appears to have long-term survival benefits following colorectal cancer resection.

Abstract
Assessment of sperm-DNA integrity is a crucial issue in male fertility. In the present study, parameters derived from the image analysis of comets after single-cell gel electrophoresis were used to analyse the types of DNA damage of frozen–thawed boar spermatozoa. Semen, frozen in a cryoprotectant-free extender or in cryoprotectant-based extenders, was analysed for DNA fragmentation and with the following comet tail measures: percentage DNA in comet tail, comet tail length and olive tail moment. The percentages of sperm DNA damage in the comet tails were classified as Type 0 (no DNA damage), Type I (very low DNA damage), Type II (light DNA damage), Type III (medium DNA damage) and Type IV (heavy DNA damage). Sperm motility characteristics and membrane integrity were assessed in the pre-freeze and frozen–thawed semen samples. Assessment of sperm DNA fragmentation and comet tail measures showed marked inter-boar variability following cryopreservation. However, consistent differences among the boars, with respect to cryo-induced sperm DNA damage, were detected by the comet tail length and olive tail moment. Besides Type IV, all types of DNA damage were detected in the cryoprotectant-based extenders. It was found that the frequency of Type II and Type III of DNA damage of frozen–thawed spermatozoa was significantly greater in the cryoprotectant-based and cryoprotectant-free extenders respectively. Deterioration in the quality of the sperm DNA integrity was concomitant with a marked decline in sperm motility characteristics, reduced plasma membrane integrity and higher lipid peroxidation and aspartate aminotransferase activity after cryopreservation. It can be suggested that the comet-assay parameters, coupled with routine laboratory tests, are useful to improve the sperm evaluations of post-thaw quality of semen from individual boars and would offer more comprehensive information for a better understanding of the degree of cryo-induced sperm-DNA damage.

Abstract
OBJECTIVES The diagnosis of cancer of unknown primary (CUP) in head and neck occurs when the treating clinicians have utilised all available diagnostic tests and failed to identify the origin of the disease. There is no agreed consensus on which diagnostic investigations to use, or the order in which to use them in, although broad recommendations exist. Small tumours arising in the tongue base can be below the limits of resolution of conventional diagnostic techniques. Given the difficulty in targeting the tongue base, current practice involves blind random biopsies, which leads to a variable detection rate. Robotically assisted surgical removal of the tongue base, tongue base mucosectomy (TBM) has been shown to improve diagnostic yield. This study reports the diagnostic hit rate for tongue base primaries using this technique. DESIGN Retrospective case review. SETTING UK Head and Neck Centres. PARTICIPANTS Patients presenting as an unknown primary, investigated with clinical examination, PET-CT and palatine tonsillectomy. MAIN OUTCOME MEASURES The detection of a primary site of head and neck cancer in the otherwise unknown primary tumour. RESULTS The primary tumour site was identified in the tongue base in 53% (n=17) of patients. In 15 patients the tumour was in the ipsliateral tongue base (88%) while in two cases (12%) the tumour was located in contra lateral tongue base. CONCLUSIONS Trans-oral robotic assisted TBM raises the possibility of identifying over 50% of tumours that would otherwise be classified as CUP. Identifying these in the contralateral tongue base has implications for treatment planning and outcome.

Abstract
BACKGROUND New cases of oropharyngeal squamous cell carcinoma (OPSCC) are routinely tested for HPV. HPV in saliva can be detected with PCR, but its clinical applicability in the context of OPSCC remains unknown. METHODS Forty-six consecutive patients diagnosed with OPSCC had pre-treatment saliva specimens collected. PCR for HPV on saliva was compared to p16 IHC and HPV DNA in situ hybridisation (ISH) on surgical biopsies. RESULTS The sensitivity and specificity of saliva testing when compared to the reference test of p16 IHC and HPV DNA ISH were 72.2% and 90%, and positive and negative predictive values were 96.3% and 47.4%. There were no adverse events. Time from last meal, smoking, alcohol drinking and physical exercise did not impact on results. CONCLUSIONS Saliva testing is a promising test to detect HPV in patients with OPSCC. A positive result could avoid the need for surgical biopsies, thereby reducing costs, patient morbidity and expedite treatment.

Abstract
OBJECTIVES The negative publicity about menopausal hormone therapy (MHT) has led to increased use of complementary and alternative medicines (CAM) and non-pharmacological interventions (NPI) for menopausal symptom relief. We report on the prevalence and predictors of CAM/NPI among UK postmenopausal women. METHOD Postmenopausal women aged 50-74 years were invited to participate in the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS). A total of 202 638 women were recruited and completed a baseline questionnaire. Of these, 136 020 were sent a postal follow-up-questionnaire between September 2006 and May 2009 which included ever-use of CAM/NPI for menopausal symptom relief. Both questionnaires included MHT use. RESULTS A total of 88 430 (65.0%) women returned a completed follow-up-questionnaire; 22 206 (25.1%) reported ever-use of one or more CAM/NPI. Highest use was reported for herbal therapies (43.8%; 9725/22 206), vitamins (42.6%; 9458/22 206), lifestyle approaches (32.1%; 7137/22 206) and phytoestrogens (21.6%; 4802/22 206). Older women reported less ever-use of herbal therapies, vitamins and phytoestrogens. Lifestyle approaches, aromatherapy/reflexology/acupuncture and homeopathy were similar across age groups. Higher education, Black ethnicity, MHT or previous oral contraceptive pill use were associated with higher CAM/NPI use. Women assessed as being less hopeful about their future were less likely to use CAM/NPI. CONCLUSION One in four postmenopausal women reported ever-use of CAM therapies/NPI for menopausal symptom relief, with lower use reported by older women. Higher levels of education and previous MHT use were positive predictors of CAM/NPI use. UKCTOCS Trial registration: ISRCTN22488978.

Abstract
This study investigated the effects of long-term extenders on post-thaw sperm quality characteristics following different holding times (HT) of boar semen at 17 and 10°C. Sperm-rich fractions, collected from five boars, were diluted in Androhep(®) Plus (AHP), Androstar(®) Plus (ASP), Safecell(®) Plus and TRIXcell(®) Plus (TCP) extenders. The extended semen samples were held for 2 hr at 17°C (HT 1) and additionally for 24 hr at 10°C (HT 2), after they were evaluated and frozen. CASA sperm motility and motion patterns, mitochondrial membrane potential (MMP), plasma membrane integrity (PMI) and normal apical ridge (NAR) acrosome integrity were assessed in the pre-freeze and frozen-thawed semen. The Vybrant Apoptosis Assay Kit was used to analyse the proportions of viable and plasma membrane apoptotic-like changes in spermatozoa. Results indicated that boar variability, extender and HT significantly affected the sperm quality characteristics, particularly after freezing-thawing. Differences in the pre-freeze semen were more marked in the sperm motion patterns between the HTs. Pre-freeze semen in HT 2 showed significantly higher VCL and VAP, whereas no marked effects were observed in the sperm membrane integrity and viability (YO-PRO-1(-) /PI(-) ) among the extenders. Post-thaw sperm TMOT and PMOT were significantly higher in the AHP and ASP extenders of HT 2 group, whereas VSL, VCL and VAP were markedly lower in the TCP extender. Furthermore, spermatozoa from the AHP- and ASP-extended semen of HT 2 group were characterized by higher MMP, PMI and NAR acrosome integrity following freezing-thawing. In most of the extenders, the incidence of frozen-thawed spermatozoa with apoptotic-like changes was greater in HT 1. The findings of this study indicate that holding of boar semen at 10°C for 24 hr in long-term preservation extenders modulates post-thaw sperm quality characteristics in an extender-dependent manner. These results will further contribute to the improvement in the cryopreservation technology of boar semen.

Abstract
We present the case of a 63 year-old male who presented with a cystic lesion of the distal pancreas. Excision and histology showed this to be a lymphoepithelial cyst. Cystic lesions of the pancreas represent a diagnostic challenge, especially when pseudocyst secondary to pancreatitis is excluded. These lesions can be broadly classified into benign, pre-malignant and malignant. Widely used imaging modalities such as CT and MRI are not able to categorically differentiate between these. More invasive procedures such as endoscopic US and FNA again do not give a cast-iron diagnosis. Our patient had a symptomatic cystic lesion in his pancreas which was excised after cross-specialty discussion. We advocate that this is the ideal way to treat patients with cystic lesions of the pancreas, with each case considered on its own merits as all current diagnostic investigations have their limitations.

Abstract
The aim of this study was to investigate the effects of storage of semen in different commercial extenders on the pre-freezing and post-thawing quality of boar spermatozoa. Semen was diluted in BTS, Androhep (AH) and Gedil (GD), stored for 24 h at 17°C, and then frozen in accordance with the cryopreservation protocol. Analyses of the quality of spermatozoa included: motility, normal apical ridge (NAR) acrosome, plasma membrane integrity (PMI), mitochondrial membrane potential (MMP), measurements of ATP content and activity of superoxidase dismutase (SOD) and glutathione peroxidase (GPx). Prior to the freezing process, no significant effect of the extender on the sperm quality parameters was noted. After thawing the spermatozoa it was demonstrated that the type of extender used influenced PMI, MMP, ATP content and activity of GPx. In the AH extender the percentage of spermatozoa with PMI and ATP content in spermatozoa was significantly higher (P<0.05) as compared to the BTS or GD extenders. In addition, semen stored in the AH was characterised by a statistically higher (P<0.05) percentage of spermatozoa with MMP and increased activity of GPx as compared with the BTS. The results obtained indicate that for the cryopreservation process, boar spermatozoa stored for 24 hours in liquid state can be used. However, the type of extender used prior to freezing may have a significant effect on the post-thawing quality of the spermatozoa. The AH extender better secured the quality of thawed boar spermatozoa as compared with the BTS or GD.

Abstract
This study investigated the effect of age- and seasonal-related variations in the composition of boar semen over a 3-year period. At the onset of 8 months of age, ejaculates were collected from four boars and allocated into three groups: 8 to 18, 19 to 30, and 31 to 42 months and were divided into two seasonal periods: autumn-winter and spring-summer. Boar variability had a significant effect on most of the analyzed semen parameters. Significantly, higher ejaculate volumes were observed in the boars older than 18 months of age during the autumn-winter period. Sperm concentration was higher in boars less than the age of 18 months of age, whereas the total sperm numbers were significantly higher during the autumn-winter period, regardless of the age group. Seasonal effects in sperm motility were more marked in boars at the age of 19 to 30 months, being significantly higher during the autumn-winter period. The proportions of spermatozoa with intact, normal apical ridge acrosome, and osmotically tolerant acrosomal membranes were markedly higher in boars at the age of 19 to 30 months during the autumn-winter period. Spermatozoa harvested during the spring-summer period were more susceptible to lipid peroxidation, irrespective of the age group. Significantly, higher levels of protein content and concentrations of nonthiol-containing antioxidant components of the seminal plasma (SP) were detected in boars less than 18 months of age during the autumn-winter period. Seasonal effects on the pH and proteinase inhibitory activity in the SP were more marked in boars less than 18 months of age, whereas alkaline phosphatase activity was greater in boars at the age of 19 to 30 months during the autumn-winter period. Substantial amounts of the thiol-containing antioxidants of the SP were detected in boars older than 18 months of age during the spring-summer period. Neither osmolality nor total antioxidant status was affected by differences in the seasonal periods or age groups. The findings of this study indicate that age- and seasonal-related variations affect the reproductive tract functions in the boar, resulting in marked changes in the biochemical composition of the semen.

Abstract
Reproductive seasonality has been shown to affect the quality of boar semen. In this study, effects of seasonal variations in the characteristics of spermatozoa and seminal plasma (SP) of fractioned ejaculates from individual boars have been investigated. Fractionated ejaculates, designated as fraction 1 (F1), fraction 2 (F2), and fraction 3 (F3), were collected from five mature boars during the autumn-winter (October through March) and spring-summer periods (April through September). A total of 10 fractionated ejaculates (F1, F2, and F3) were collected from each boar within each seasonal period. Assessments of the sperm quality characteristics included computer-assisted sperm analysis motion patterns, mitochondrial membrane potential (MMP), plasma membrane integrity, normal apical ridge acrosomes, and DNA fragmentation. Besides SDS-PAGE and densitometric analyses of the SP proteins, the antiperoxidant activity was monitored. There were marked differences in the sperm quality characteristics among the boars, except for sperm MMP. Distinct seasonal differences (P < 0.05) were observed in the ejaculate volume of F3 during the autumn-winter and spring-summer periods (107.78 ± 5.45 and 87.80 ± 4.75 mL, respectively). Significantly higher (P < 0.05) sperm concentration and the total number of spermatozoa in the fraction were observed during the autumn-winter period. Seasonal effects in MMP and plasma membrane integrity were manifested in significantly higher (P < 0.05) percentages of spermatozoa with functional mitochondria and intact plasma membrane during the autumn-winter period. However, the seasonal effects were less marked in either sperm normal apical ridge acrosomes or sperm DNA fragmentation. Sodium dodecyl sulfate-PAGE and densitometric analyses revealed marked variations in the protein composition of the SP profiles among the boars, regardless of the ejaculate fraction and seasonal period. Distinct seasonal variations, observed in the SDS-PAGE profiles, were associated with an abundance of protein fractions of low-molecular and high-molecular weight components, particularly during the autumn-winter period. There were wide variations in antiperoxidant activity in the SP among the boars, being significantly higher in the autumn-winter period, irrespective of the ejaculate fraction. It can be suggested that marked deterioration of the quality of fractionated ejaculates during the spring-summer period was probably caused by impaired reproductive function in the boar.

Abstract
STUDY PURPOSE A population-based risk stratification programme for ovarian cancer (OC) may improve OC survival by identifying women at increased risk and implementing an appropriate risk management strategy. The present study explored attitudes towards an OC risk stratification programme incorporating predictive genetic testing and risk-stratified screening as part of a larger study investigating OC screening. METHODS Focus groups consisting of 56 members of the general public (mean age 45 years; 34% non-white) were conducted using a hypothetical scenario. The group sessions were recorded, transcribed verbatim and analysed using Framework Analysis. RESULTS There was strong support for the proposed programme. Genetic testing and risk-stratified screening was thought to raise awareness, offer reassurance and offer opportunities for early intervention. Anxiety was only mentioned in relation to receiving a diagnosis of OC and not with screening per se. Perhaps because lay models of cancer already embrace both environmental and genetic factors, a low-risk result was not anticipated to result in a false sense of immunity. Unexpectedly, participants also wanted to receive cancer prevention advice in conjunction with genetic testing; screening alone was not regarded as sufficient. CONCLUSION The encouraging results from this small study warrant further large-scale research into risk-stratified OC screening.

Abstract
PURPOSE We determined the efficacy and safety of pelvic floor myofascial physical therapy compared to global therapeutic massage in women with newly symptomatic interstitial cystitis/painful bladder syndrome. MATERIALS AND METHODS A randomized controlled trial of 10 scheduled treatments of myofascial physical therapy vs global therapeutic massage was performed at 11 clinical centers in North America. We recruited women with interstitial cystitis/painful bladder syndrome with demonstrable pelvic floor tenderness on physical examination and a limitation of no more than 3 years' symptom duration. The primary outcome was the proportion of responders defined as moderately improved or markedly improved in overall symptoms compared to baseline on a 7-point global response assessment scale. Secondary outcomes included ratings for pain, urgency and frequency, the O'Leary-Sant IC Symptom and Problem Index, and reports of adverse events. We compared response rates between treatment arms using the exact conditional version of the Mantel-Haenszel test to control for clustering by clinical center. For secondary efficacy outcomes cross-sectional descriptive statistics and changes from baseline were calculated. RESULTS A total of 81 women randomized to the 2 treatment groups had similar symptoms at baseline. The global response assessment response rate was 26% in the global therapeutic massage group and 59% in the myofascial physical therapy group (p=0.0012). Pain, urgency and frequency ratings, and O'Leary-Sant IC Symptom and Problem Index decreased in both groups during followup, and were not significantly different between the groups. Pain was the most common adverse event, occurring at similar rates in both groups. No serious adverse events were reported. CONCLUSIONS A significantly higher proportion of women with interstitial cystitis/painful bladder syndrome responded to treatment with myofascial physical therapy than to global therapeutic massage. Myofascial physical therapy may be a beneficial therapy in women with this syndrome.

Abstract
OBJECTIVE Hot flushes and night sweats (HFs/NSs) are the main menopausal symptoms, but few studies have been adequately powered to examine the dimensions or predictors of experiencing HFs/NSs. We report on these variables in a large UK cohort of postmenopausal women. DESIGN Cross-sectional cohort study. SETTING UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) cohort. POPULATION A cohort of 202,638 postmenopausal women, aged 50-74 years, without oophorectomy, recruited to UKCTOCS between 2001 and 2005. METHODS Women completed a follow-up questionnaire, and those aged 54-65 years were mailed a survey in July 2008. MAIN OUTCOME MEASURES Hot flush prevalence and hot flush rating scale. RESULTS Of the 15,000 women mailed, 10,418 returned completed questionnaires; 90% had previously had HFs/NSs. Despite being on average 10 years postmenopausal, 54% experienced HFs/NSs (frequency of 33 per week with mean problem rating 4/10) that persisted across the age range. Past hysterectomy (OR 1.50, 95% CI 1.19-1.86), ever having smoked (OR 1.27, 95% CI 1.11-1.46) and alcohol consumption (current units) (OR 1.05, 95% CI 1.01-1.09) predicted ever having had HFs/NSs. Anxiety (OR 3.09, 95% CI 2.57-3.72), hysterectomy (OR 2.74, 95% CI 2.32-3.25), depressed mood (OR 1.57, 95% CI 1.24-1.99), years since last menstrual period (OR 0.95, 95% CI 0.94-0.96) and education (above and below 18 years) (OR 0.98, 95% CI 0.97-0.99) predicted the current prevalence of HFs/NSs. Few predictors of frequency were identified, but problem rating was associated with depressed mood, hysterectomy, skirt size increase and frequency of HFs/NSs. Past hormone therapy users who had discontinued treatment were more likely to have HFs/NSs that were more frequent and problematic. CONCLUSIONS To date, this is the largest UK study of the experience of HFs/NSs amongst older postmenopausal women. HFs/NSs are more prevalent in this age band than has previously been assumed. These findings and the associations of smoking, hysterectomy, anxiety, depressed mood and hormone therapy use with the experience of HFs/NSs have implications for prevention and symptom management.

Abstract
In this study, we tested the hypothesis whether the neutral Comet assay (NCA) and the Sperm-Sus-Halomax (SSH) test kit could provide similar measurements of post-thaw DNA fragmentation of boar spermatozoa. Whole ejaculates or sperm-rich fractions of boar semen were frozen in an extender containing lactose, lipoprotein fractions isolated from ostrich egg yolk (LPFo), glycerol (lactose-LPFo-G) or in a standard boar semen extender (K3), without the addition of cryoprotective substances. In all boars, both the NCA and SSH test showed similar levels of post-thaw sperm DNA fragmentation in samples of the same ejaculates, regardless of the ejaculate collection procedure and extender. Yet, the levels of post-thaw sperm DNA damage, detected by the NCA and SSH test, were more accentuated in spermatozoa frozen in the absence of cryoprotective substances. Both the NCA and SSH detected variations among individual boars in terms of post-thaw sperm DNA fragmentation. Agreement between the measurements of the NCA and SSH was confirmed by scatter plots of differences, suggesting that the DNA integrity tests could detect the same sperm populations, which were susceptible to cryo-induced DNA damage. The findings of this study indicate that the NCA and the SSH test are effective in detecting similar levels of sperm DNA fragmentation and reinforce their importance in the assessment of frozen-thawed boar semen quality.

Abstract
Antioxidants secreted by the reproductive tract protect spermatozoa against the toxic effects of reactive oxygen species (ROS) after ejaculation. This study aimed at characterizing the level of antioxidant protection in boar cauda epididymidal spermatozoa and fluids of the cauda epididymidis, vesicular and prostate glands. Also, this study investigated the effect of a 5-h period of dialysis on the antioxidant capacity of boar seminal plasma. Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR), glutathione transferase (GST) and phospholipid hydroperoxide glutathione peroxidase (PHGPx) activities were monitored in the cauda epididymidal spermatozoa or reproductive tract fluids. Also, the concentrations of total glutathione (GSH + GSSG), L-ergothioneine (ERT) and l-ascorbate and the total antioxidant status (TAS) of the fluids were measured. It was found that the cauda epididymidal spermatozoa exhibited high SOD activity and relatively low activity of PHGPx. The relative amounts of GPx, GR and GST activities in the cauda epididymidal spermatozoa were negligible, whereas CAT activity was undetectable. Greater SOD activity was found in the fluids of the cauda epididymidis and prostate gland. Furthermore, the prostate gland fluid appeared to be the main source of CAT activity in the seminal plasma, whereas the highest level of GPx activity was derived from the cauda epididymidal fluid. The reproductive tract fluids exhibited negligible amounts of GR and GST activities. It seemed that the significant amounts of GSH + GSSG, ERT and L-ascorbate in the reproductive tract fluids could have an ameliorative effect on the level of TAS in the seminal plasma. Dialysis had a marked effect on the total antioxidant capacity of the seminal plasma, which was manifested in greater activity of SOD and GPx. The findings of this study confirmed that the scavenging potential of the seminal plasma is dependent on the contributions of different antioxidants, originating in various fluids of boar reproductive tract.
