Abstract
PURPOSE/OBJECTIVE(S) To evaluate the association between regular vaginal dilation and/or sexual activity and vaginal morbidity in locally advanced cervical cancer patients after definitive radiochemotherapy and image-guided adaptive brachytherapy from the EMBRACE I study. MATERIALS/METHODS Physician-assessed vaginal morbidity (CTCAE v.3), vaginal dilation and patient-reported sexual activity (EORTC QLQ CX24) were assessed at baseline, every 3 months in the 1st year, every 6 months in the 2nd and 3rd year and yearly thereafter. For this longitudinal analysis, a subgroup of patients was selected with at least 3 follow-ups with information on vaginal dilation and/or sexual activity. Vaginal penetration summarized either the use of vaginal dilators or sexual activity or both. Regular vaginal penetration was defined if reported in ≥50%, infrequent if reported in <50% and absent if reported in 0% of follow-ups. Actuarial estimates of vaginal morbidity were calculated with Kaplan-Meier method and included the individual symptoms: vaginal dryness, stenosis, mucositis and bleeding. Group comparisons were evaluated with the log-rank test. RESULTS The EMBRACE I study included 1416 patients overall (2008-2015); the subgroup of patients for this longitudinal evaluation consists of 882 patients, with a median follow-up of 60 months (IQR 47-77). Of those, 565 (64%) reported regular, 205 (23%) infrequent and 112 (13%) no penetration. Reporting regular penetration was associated with a significantly lower risk of vaginal stenosis G≥2 of 23% at 5 years, compared to reporting of infrequent (37%) and no penetration (36%, p≤0.001). However, reporting regular penetration was associated with a significantly higher risk for vaginal dryness G≥1 (72% vs. 69% vs. 62%, respectively, p = 0.038) and bleeding G≥1 (61% vs. 40% vs. 25%, respectively, p≤0.001). No associations were seen for G≥1 vaginal stenosis, G≥2 dryness, G≥2 bleeding and G≥1/G≥2 mucositis. CONCLUSION Regular penetration (defined as vaginal dilation and/or sexual activity) was associated with lower risk for vaginal stenosis G≥2, but higher risk for vaginal dryness G≥1 and bleeding G≥1. Mild vaginal dryness seems to become apparent in particular for patients experiencing vaginal penetration. Minor vaginal blood loss during dilation and/or sexual activity is commonly reported by patients, resulting from atrophy of the vaginal mucosa and/or telangiectasia. While both of these G≥1 symptoms can be managed with lubricants, moisturizer and/or hormonal replacement therapy, G≥2 vaginal stenosis represents an irreversible fibrotic adverse event that can cause dyspareunia in many cancer patients. These long-term data support clinical recommendations for dilation and/or sexual activity after radiotherapy.

Associations between diabetes status and grip strength trajectory sub-groups in adulthood: findings from over 16 years of follow-up in the MRC National Survey of Health and Development. BMC Geriatr 2023; 23:213. [PMID: 37016329 PMCID: PMC10074704 DOI: 10.1186/s12877-023-03871-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 03/03/2023] [Indexed: 04/06/2023] Open
Abstract
BACKGROUND Cross-sectional studies suggest a relationship between diabetes status and weaker grip strength (GS) in adulthood and limited evidence from longitudinal studies has focussed on the association with average change in GS. We aimed to investigate whether diabetes status was related to membership of distinct GS trajectories in mid-to-late adulthood in 2,263 participants in the Medical Research Council National Survey of Health and Development. METHODS Grip strength (kg) was measured at 53, 60-64 and 69 years. Pre-/diabetes was defined at 53 years based on HbA1c > 5.6% and/or doctor-diagnosis of diabetes. Sex-specific latent class trajectory models were developed and multinomial logistic regression was used to investigate the association between pre-/diabetes status and membership into GS trajectory classes. RESULTS For both males and females, a 3-class solution ('High', 'Intermediate', 'Low') provided the best representation of the GS data and the most plausible solution. There was no evidence that pre-/diabetes status was associated with class membership in either sex: e.g., adjusted odds ratios of being in the 'Low' class (vs. 'High') for males with pre-/diabetes (vs. no-diabetes) was 1.07 (95% CI:0.45,2.55). CONCLUSION Using a flexible data-driven approach to identify GS trajectories between 53 and 69 years, we observed three distinct GS trajectories, all declining, in both sexes. There was no association between pre-/diabetes status at 53 years and membership into these GS trajectories. Understanding the diabetes status-GS trajectories association is vital to ascertain the consequences that projected increases in pre-/diabetes prevalence's are likely to have.

Abstract
Background
Identification of athletes with cardiac inflammation following COVID-19 can prevent exercise fatalities. The efficacy of pre and post COVID-19 infection electrocardiograms (ECGs) for detecting athletes with myopericarditis has never been reported. We aimed to assess the prevalence and diagnostic significance of novel 12-lead ECG patterns following COVID-19 infection in elite soccer players.
Methods
We conducted a multicentre study over a 2-year period involving 5 centres and 34 clubs and compared pre COVID and post COVID ECG changes in 455 consecutive athletes. ECGs were reported in accordance with the International recommendations for ECG interpretation in athletes. The following patterns were considered abnormal if they were not detected on the pre COVID-19 infection ECG: (a) biphasic T-waves; (b) reduction in T-wave amplitude by 50% in contiguous leads; (c) ST-segment depression; (d) J-point and ST-segment elevation >0.2 mV in the precordial leads and >0.1 mV in the limb leads; (e) tall T-waves ≥1.0 mV (f) low QRS-amplitude in >3 limb leads and (g) complete right bundle branch block. Athletes exhibiting novel ECG changes underwent cardiovascular magnetic resonance (CMR) scans. One club mandated CMR scans for all 28 (6%) athletes, despite the absence of cardiac symptoms or ECG changes.
Results
Athletes were aged 22±5 years (89% male and 57% white). 65 (14%) athletes reported cardiac symptoms. The mean duration of illness was 3±4 days. The post COVID ECG was performed 14±16 days following a positive PCR. 440 (97%) athletes had an unchanged post COVID-19 ECG. Of these, 3 (0.6%) had cardiac symptoms and CMRs resulted in a diagnosis of pericarditis. 15 (3%) athletes demonstrated novel ECG changes following COVID-19 infection. Among athletes who demonstrated novel ECG changes, 10 (67%) reported cardiac symptoms. 13 (87%) athletes with novel ECG changes were diagnosed with inflammatory cardiac sequelae; pericarditis (n=6), healed myocarditis (n=3), definitive myocarditis (n=2), and possible/probable myocarditis (n=2). The overall prevalence of inflammatory cardiac sequelae based on novel ECG changes was 2.8%. None of the 28 (6%) athletes, who underwent a CMR, in the absence of cardiac symptoms or novel ECG changes revealed any abnormalities. Athletes revealing novel ECG changes, had a higher prevalence of cardiac symptoms (67% v 12% p<0.0001) and longer symptom duration (8±8 days v 2±4 days; p<0.0001) compared with athletes without novel ECG changes. Among athletes without cardiac symptoms, the additional yield of novel ECG changes to detect cardiac inflammation was 20% (n=3).
Conclusions
3% of elite soccer players demonstrated novel ECG changes post COVID-19 infection, of which almost 90% were diagnosed with cardiac inflammation during subsequent investigation. Most athletes with novel ECG changes exhibited cardiac symptoms. Novel ECGs changes contributed to a diagnosis of cardiac inflammation in 20% of athletes without cardiac symptoms.

Abstract
Introduction
Multiple approaches are used to describe MLTC, including counts and indices (weighted counts). However, few studies have directly compared different approaches which would be helpful for the design of future MLTC studies. We therefore aimed to compare the prevalence of MLTC and association with emergency hospital admission characterised using different approaches within the same dataset.
Method
We used baseline data from 501,596 UK Biobank participants (age 37-73y) combined with linked hospital episode statistics to characterise MLTC using four approaches: count of body systems affected (CB); count of 43 conditions (CC); Byles index (BI); and Charlson comorbidity index (CCI). For each we performed survival analyses to test associations to a combined endpoint of first emergency admission or death over five years from baseline interview, adjusting for age and sex. We used Harrell’s C-index to compare the discriminant value of the four approaches for the combined endpoint.
Results
Prevalence of two or more positive responses (indicating the presence of MLTC) was 45% for CB, 33% for CC, 6% for BI and 2% for CCI. 95,812 (19%) participants had one or more emergency admission or died in the first five years. All four approaches were associated with greater rates of admission/death. For example, using CC, compared to those with zero conditions those with one had 1.42 (95% CI 1.39,1.45), those with two 1.94 (95% CI 1.90,1.98), and those with 3+ conditions had 3.11 (95% CI 3.05,3.17) times greater rates. The predictive value of the four approaches was modest (C-indices ranging from 0.60 to 0.63).
Conclusion
The counts classified a greater proportion of the sample as having MLTC than the indices, highlighting that prevalence estimates of MLTC may vary depending on the approach used. All approaches had strong statistical associations with admission, but only moderate ability to identify individual participants at risk.

Abstract
BackgroundEvidence suggests that associations of lower socioeconomic position (SEP) with increased incidence of osteoarthritis (OA) are partially mediated by obesity. Obesity and lower SEP are also associated with increased symptoms in OA (i.e. pain/function). However, few studies have investigated whether obesity and lower SEP are also associated with increased risk of knee joint replacement surgeries (kJRS).ObjectivesTo investigate the relationships of obesity and SEP at time of diagnosis with kJRS at follow-up in people with knee OA (kOA).MethodsThe English Longitudinal Study of Ageing is a nationally representative panel study of adults aged ≥50 years with biannual waves of data collection (2002–2019). Participants who self-reported OA diagnosis for the first time in waves 2–8 and knee pain in the same or previous wave of diagnosis were defined as having kOA (baseline). Participants with at least one body mass index (BMI) measurement and one follow-up assessment were included. Underweight/normal weight, overweight and obesity were defined using BMI <25 kg/m2, 25–30 kg/m2 and ≥30kg/m2, respectively. Education, occupation (current or last occupation if retired), wealth quintiles (all individual-based) and index of multiple deprivation quintiles (area-based) were used as SEP indicators. Outcome was the first self-reported kJRS (left or right knee) in waves 3–9. Cox proportional hazards models were used to investigate the associations of obesity and SEP with kJRS, controlling for baseline covariates. Person year follow up was calculated from baseline to either a) date of self-reported kJRS, b) loss to follow-up, c) end of follow-up (wave 9).ResultsThe analysis sample included 1499 people who reported kOA and had ≥1 BMI measure (62.3% female; mean age 66.5y (SD 9.4); 96% white; 47.4% obese). Number of person-years included in the analysis was 8427. Over a mean follow-up of 4.7 years (SD 2.8), 144 (9.6%) reported having kJRS. Obese kOA patients were more likely to report kJRS than non-obese patients (adjHR 1.89 (95% CI 1.33, 2.68)), independent of age, gender, SEP, cardiovascular disease (self-reported) and HbA1c values (measured from collected blood samples). Education and occupation were not associated with kJRS. However, those living in the most deprived areas and with the least amount of wealth were less likely to undergo kJRS compared with the least deprived and wealthiest (HRs adjusted for age and gender 0.37 (95% CI 0.19, 0.73) and 0.55 (95% CI 0.33, 0.93), respectively). There was no evidence of interactions between obesity and SEP indicators.ConclusionObesity increased the likelihood of undergoing kJRS in kOA patients. Therefore, reducing obesity in kOA patients may help to reduce the need for kJRS. Area-deprivation and lower wealth were associated with lower likelihood of kJRS. Taken together with findings from other studies which report associations between lower SEP and worse OA symptoms, our results suggest that there may be social inequalities in the provision of kJRS in England.Table 1.The relationships between obesity at baseline and rates of knee joint replacement surgery over a mean of 4.7 (SD 2.8) years in follow-up in those with knee OA at baseline in the English Longitudinal Study of AgeingPredictorsHR (95% CI)UnadjustedAdjusted for age and genderAdjusted for age, gender and SEPAdjusted for age, gender, SEP, CVD and HbA1cObesity1.56 (1.12, 2.17)1.63 (1.17, 2.28)1.77 (1.26, 2.50)1.89 (1.33, 2.68)Non-obesityrefrefrefrefObesity3.53 (1.77, 7.02)3.58 (1.80, 7.12)4.01 (2.01, 8.03)4.35 (2.16, 8.74)Overweight2.91 (1.43, 5.91)2.81 (1.38, 5.73)2.93 (1.44, 5.98)2.98 (1.46, 6.09)Underweight/normal weightrefrefrefrefBMI per 1 kg/m2 increment1.05 (1.02, 1.07)1.05 (1.03, 1.08)1.06 (1.04, 1.09)1.07 (1.04, 1.10)HR, hazard ratio; CI, confidence interval; SEP, socioeconomic position; CVD, cardiovascular disease; ref, reference category; BMI, body mass index.Disclosure of InterestsNone declared

Abstract
Abstract
Introduction
Weak grip strength is associated with a range of adverse health outcomes, and an accelerated decline in grip strength confers an even greater risk. To date there has been limited research into the factors associated with change in grip strength in mid-life. Using data from UK Biobank our aim was to investigate the associations of long-term conditions (LTCs), multimorbidity and lifestyle factors with patterns of change in grip strength.
Methods
We used data from 44,315 UK Biobank participants with grip strength measured at baseline (2006–10) and a subsequent study visit around nine years later. At baseline, participants’ LTCs were self-reported and categorised against a hierarchy. Multimorbidity was characterised by the number of LTC categories present (0, 1, 2 and 3+). Lifestyle factors (body mass index (BMI), smoking, diet and physical activity) were also assessed. Change in grip strength was grouped into four patterns: decline, stable low, stable high or reference (no change or increase) and used as the outcome in multinomial logistic regression models.
Results
Most LTC categories were associated with adverse patterns of change in grip strength (stable low and/or decline): for example, musculoskeletal/trauma conditions were associated with an increased risk of the stable low pattern (Relative Risk Ratio [RRR] = 1.63; 95% Confidence Interval [CI] 1.49–1.79). Multimorbidity and lifestyle factors had independent associations with grip strength change: those with 3+ categories of LTCs were more likely to experience decline in grip strength (RRR = 1.18;95% CI 1.08–1.28) compared to those with no LTCs. Low physical activity was associated with adverse patterns of grip strength, while raised BMI had divergent associations (both the decline and stable high patterns of grip strength change).
Conclusion
Individuals living with multimorbidity and those with lifestyle risk factors such as low physical activity are at increased risk of loss of strength over time.

Abstract
BACKGROUND AND OBJECTIVES Myocardial dysfunction and coronary abnormalities are prominent features of multisystem inflammatory syndrome in children (MIS-C). In this study we aim to evaluate the early and midterm outcomes of MIS-C. METHODS This is a longitudinal 6-month cohort study of all children admitted and treated for MIS-C from April 17 to June 20, 2020. Patients were followed ∼2 weeks, 8 weeks, and 6 months postadmission, with those with coronary aneurysms evaluated more frequently. RESULTS Acutely, 31 (62%) patients required intensive care with vasoactive support, 26 (52%) had left ventricular (LV) systolic dysfunction, 16 (32%) had LV diastolic dysfunction, 8 (16%) had coronary aneurysms (z score ≥2.5), and 4 (8%) had coronary dilation (z score <2.5). A total of 48 patients (96%) received immunomodulatory treatment. At 2 weeks, there was persistent mild LV systolic dysfunction in 1 patient, coronary aneurysms in 2, and dilated coronary artery in 1. By 8 weeks through 6 months, all patients returned to functional baseline with normal LV systolic function and resolution of coronary abnormalities. Cardiac MRI performed during recovery in select patients revealed no myocardial edema or fibrosis. Some patients demonstrated persistent diastolic dysfunction at 2 weeks (5, 11%), 8 weeks (4, 9%), and 6 months (1, 4%). CONCLUSIONS Children with MIS-C treated with immunomodulators have favorable early outcomes with no mortality, normalization of LV systolic function, recovery of coronary abnormalities, and no inflammation or scarring on cardiac MRI. Persistence of diastolic dysfunction is of uncertain significance and indicates need for larger studies to improve understanding of MIS-C. These findings may help guide clinical management, outpatient monitoring, and considerations for sports clearance.

Abstract
OBJECTIVE Point-of-care ultrasound (POC US) has been increasingly used by intensive care physicians. Growing use of POC US necessitates defining distinct clinical indications for its application, as well as structured POC US training programs. Homogeneous approach to POC US education combined with rigorous quality assurance should further enable POC US to become standard-of-care clinical tool. This study aimed to present the first, innovative, and structured POC US program in neonatal-perinatal medicine field. In addition, we reviewed the availability of the POC US training programs across different medical specialties. STUDY DESIGN Available English-language publications on POC US training programs in general and neonatal-perinatal medicine were reviewed in this study. DISCUSSION Mounting body of evidence suggests improved procedural completion rates, as well as clinical decision making with the use of POC US. However, limited research supported the existence of structured, comprehensive POC US programs. It was recognized that medical institutions need to develop syllabuses, teach, and credential increasing number of health care professionals in the use of POC US. We defined intuitive educational strategy that encompasses POC US clinical indications, educational curriculum, scanning protocols, competence evaluation, and finally credentialing process. In addition, we offered description of the imaging quality assurance, as well as POC US coding, and reimbursement. CONCLUSION Future efforts need to be dedicated to the ongoing development of neonatal POC US as a clinical instrument. It should allow for eventual paradigm change and improved effectiveness in management of critically ill neonates.

Introduction
The 2010 Task Force Criteria (TFC) for the diagnosis of arrhythmogenic right ventricular cardiomyopathy (A(R)VC) in 1st degree relatives includes an abnormality in a single parameter of the signal averaged ECG (SAECG). SAECG normal ranges were derived predominately from ischaemic heart disease patients, so may not be applicable in an A(R)VC population. There remain concerns that the SAECG is not specific enough and its role in the diagnosis of A(R)VC is under scrutiny.
Purpose
to improve the diagnostic utility of the SAECG
Methods
Patients with an A(R)VC diagnosis and 1st degree family members (FM) under follow-up at a single inherited cardiac conditions (ICC) centre were included. All cases were independently reviewed by 3 cardiologists experienced in the diagnosis and management of A(R)VC. All SAECGs included were free from artefact. TFC clinical variables and genetic status were recorded for each patient. Where tests had been repeated the most recent values were used. Because of concerns about the use of a single abnormal SAECG parameter in making a clinical diagnosis we required ≥2 abnormal SAECG parameters, or a confirmed genetic mutation to make a diagnosis. A diagnosis of false positive SAECG was made with ≥2 abnormalities when the individual was known not to carry the familial pathogenic mutation.
Results
A study population of 160 patients (male 103 (64%), age 46yrs (range 18-85yrs); 41 pro-bands and 119 FM. 62(52%) FM had a clinical diagnosis of AVC, with ARVC the pre-dominant phenotype 51(82%). A pathogenic genetic variant was identified in 24(47%) of FM with ARVC. The SAECG data is presented graphically for each parameter. A clinical diagnosis of ARVC was made on the basis of an affected 1st degree FM and an abnormal SAECG in 24(47%) of FM. Of these, 16(67%) had three abnormal SAECG parameters, 6(25%) two and 2(8%) a single abnormal parameter. Both patients with only one abnormal SAECG parameter carry a pathogenic variant. In total 88% of FM with ARVC, and 32% of FM without AVC had an abnormal SAECG as per current TFC. False positive values were mainly in fQRS duration (17/18), but also LAS40 (5/18), and RMS40 (2/18). By redefining an abnormal fQRS duration to be ≥118ms, false positives are reduced from 17 to 4. In addition, if there is a requirement for a 2nd abnormality then the false positives are reduced to 2 (4%). By adjusting the diagnostic criteria to fQRS duration ≥118ms, with a 2nd abnormal parameter or known pathogenic gene carrier status none of the 24 FM with a clinical diagnosis on abnormal SAECG alone would change diagnostic classification.
Conclusion
The SAECG is useful in family screening as it is frequently the only test to show an abnormality. However, the current TFC reference values lack specificity. By redefining an abnormal fQRS as ≥118ms with the requirement of a 2nd abnormal parameter, specificity is increased to 96%, with no significant change in sensitivity. Abstract Figure.

Abstract
Abstract Body Adults with ADHD describe self-medicating with cannabis. A small number of psychiatrists in the US prescribe cannabis medication for ADHD, despite there being no evidence from trials. The EMA-C trial (Experimental Medicine in ADHD-Cannabinoids) was a pilot randomised placebo-controlled experimental study of a cannabinoid medication, Sativex Oromucosal Spray, in 30 adults with ADHD. The primary outcome was cognitive performance and activity level using the QbTest. Secondary outcomes included ADHD and emotional lability (EL) symptoms. From 17.07.14-18.06.15, 30 participants were randomly assigned to the active (n=15) or placebo (n=15) group. For the primary outcome, no significant difference was found in the intent-to-treat analysis although the overall pattern of scores was such that the active group usually had scores that were better than the placebo group (Est=-0.17,95%CI-0.40-0.07, p=0.16, n=15/11 active/placebo). For secondary outcomes Sativex was associated with a nominally significant improvement in hyperactivity/impulsivity (p=0.03) and a cognitive measure of inhibition (p=0.05), and a trend towards improvement for inattention (p=0.10) and EL (p=0.11). Per-protocol effects were higher. Results did not meet significance following adjustment for multiple testing. One serious (muscular seizures/spasms) and three mild adverse events occurred in the active group and one serious (cardiovascular problems) adverse event in the placebo group. Adults with ADHD may represent a subgroup of individuals who experience a reduction of symptoms and no cognitive impairments following cannabinoid use. While not definitive, this study provides preliminary evidence supporting the self-medication theory of cannabis use in ADHD and the need for further studies of the endocannabinoid system in ADHD. Disclosure During this work-RC was a Ph.D. student funded by a grant to PA from Vifor Pharma. PA received funds (consultancy/sponsored talks/research/education) from Shire, Lilly, Novartis, Janssen, PCMScientific, Vifor Pharma, QBTech. Sativex was free from GW Pharm

Life course longitudinal growth and risk of knee osteoarthritis at age 53 years: evidence from the 1946 British birth cohort study. Osteoarthritis Cartilage 2021; 29:335-340. [PMID: 33383179 PMCID: PMC7955286 DOI: 10.1016/j.joca.2020.12.012] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Revised: 12/01/2020] [Accepted: 12/21/2020] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To examine the relationship between height gain across childhood and adolescence with knee osteoarthritis in the MRC National Survey of Health and Development (NSHD). MATERIALS AND METHODS Data are from 3035 male and female participants of the NSHD. Height was measured at ages 2, 4, 6, 7, 11 and 15 years, and self-reported at ages 20 years. Associations between (1) height at each age (2) height gain during specific life periods (3) Super-Imposition by Translation And Rotation (SITAR) growth curve variables of height size, tempo and velocity, and knee osteoarthritis at 53 years were tested. RESULTS In sex-adjusted models, estimated associations between taller height and decreased odds of knee osteoarthritis at age 53 years were small at all ages - the largest associations were an OR of knee osteoarthritis of 0.9 per 5 cm increase in height at age 4, (95% CI 0.7-1.1) and an OR of 0.9 per 5 cm increase in height, (95% CI 0.8-1.0) at age 6. No associations were found between height gain during specific life periods or the SITAR growth curve variables and odds of knee osteoarthritis. CONCLUSIONS There was limited evidence to suggest that taller height in childhood is associated with decreased odds of knee osteoarthritis at age 53 years in this cohort. This work enhances our understanding of osteoarthritis predisposition and the contribution of life course height to this.

Abstract
OBJECTIVE To investigate differences in local tumour staging between clinical examination and MRI and differences between FIGO 2009, FIGO 2018 and TNM in patients with primary cervical cancer undergoing definitive radio-chemotherapy. METHODS Patients from the prospective observational multi-centre study "EMBRACE" were considered for analysis. All patients had gynaecological examination and pelvic MRI before treatment. Nodal status was assessed by MRI, CT, PET-CT or lymphadenectomy. For this analysis, patients were restaged according to the FIGO 2009, FIGO 2018 and TNM staging system. The local tumour stage was evaluated for MRI and clinical examination separately. Descriptive statistics were used to compare local tumour stages and different staging systems. RESULTS Data was available from 1338 patients. For local tumour staging, differences between MRI and clinical examination were found in 364 patients (27.2%). Affected lymph nodes were detected in 52%. The two most frequent stages with FIGO 2009 are IIB (54%) and IIIB (16%), with FIGO 2018 IIIC1 (43%) and IIB (27%) and with TNM T2b N0 M0 (27%) and T2b N1 M0 (23%) in this cohort. CONCLUSIONS MRI and clinical examination resulted in a different local tumour staging in approximately one quarter of patients. Comprehensive knowledge of the differential value of clinical examination and MRI is necessary to define one final local stage, especially when a decision about treatment options is to be taken. The use of FIGO 2009, FIGO 2018 and TNM staging system leads to differences in stage distributions complicating comparability of treatment results. TNM provides the most differentiated stage allocation.

A comprehensive assessment of risk factors for falls in middle-aged adults: co-ordinated analyses of cohort studies in four countries. Osteoporos Int 2019; 30:2099-2117.

Abstract
UNLABELLED We identified demographic, health and lifestyle factors associated with falls in adults aged 50-64 years from Australia, The Netherlands, Great Britain and Ireland. Nearly all factors were associated with falls, but there were differences between countries and between men and women. Existing falls prevention programs may also benefit middle-aged adults. INTRODUCTION Between ages 40-44 and 60-64 years, the annual prevalence of falls triples suggesting that middle age may be a critical life stage for preventive interventions. We aimed to identify demographic, health and lifestyle factors associated with falls in adults aged 50-64 years. METHODS Harmonised data were used from four population-based cohort studies based in Australia (Australian Longitudinal Study on Women's Health, n = 10,641, 51-58 years in 2004), Ireland (The Irish Longitudinal Study on Ageing, n = 4663, 40-64 years in 2010), the Netherlands (Longitudinal Ageing Study Amsterdam, n = 862, 55-64 years in 2012-13) and Great Britain (MRC National Survey of Health and Development, n = 2987, 53 years in 1999). Cross-sectional and prospective associations of 42 potential risk factors with self-reported falls in the past year were examined separately by cohort and gender using logistic regression. In the absence of differences between cohorts, estimates were pooled using meta-analysis. RESULTS In cross-sectional models, nearly all risk factors were associated with fall risk in at least one cohort. Poor mobility (pooled OR = 1.71, CI = 1.34-2.07) and urinary incontinence (OR range = 1.53-2.09) were consistently associated with falls in all cohorts. Findings from prospective models were consistent. Statistically significant interactions with cohort and sex were found for some of the risk factors. CONCLUSION Risk factors known to be associated with falls in older adults were also associated with falls in middle age. Compared with findings from previous studies of older adults, there is a suggestion that specific risk factors, for example musculoskeletal conditions, may be more important in middle age. These findings suggest that available preventive interventions for falls in older adults may also benefit middle-aged adults, but tailoring by age, sex and country is required.

Abstract
BACKGROUND Previous studies linking social activity and disability have been limited by focussing on self-reported physical performance in older adults (>65). We examined whether social participation in mid-life is associated with objective and subjective measures of physical performance in older age. METHODS Participants of the Medical Research Council National Survey of Health and Development reported their involvement in social activities at ages 43 and 60-64 years; frequency of such involvement was classified into thirds. Physical performance was measured at age 60-64 using: grip strength; standing balance; chair rises; timed get-up-and-go; self-reported physical function from the Short Form-36. Multivariable regression was used to examine longitudinal associations between social participation and each physical performance measure. We also investigated whether change in social participation between 43 and 60-64 was associated with each outcome. RESULTS In fully adjusted models, higher frequency of social participation at 43 was associated with faster chair rise (1.42 repetitions/min, 95% CI 0.45-2.39) and timed get-up-and-go speed (2.47 cm/s, 95% CI 0.27-4.67) and lower likelihood of self-report limitations (OR of low physical function 0.67, 95% CI 0.50-0.91) at 60-64 compared with low frequency. Better performance in objectively measured outcomes was observed only if higher social participation persisted over time whereas lower odds of self-reported limitations were found in all groups when compared to those with persistently low participation (ORs 0.43-0.56, all P≤0.02). CONCLUSION Our findings suggest that associations between higher levels of social participation in mid-life and better physical performance exist only if this social participation persists through to older age.

Abstract
BACKGROUND Sleep disordered breathing has been closely linked to pathogenesis, poor control of hypertension, and progression of chronic kidney disease (CKD). Though hypertension and CKD are highly prevalent in Nigeria, the effects of sleep disorders on CKD and hypertension phenotypes have not been widely studied. This study investigated the relationship between self-reported sleep disorders, and ambulatory blood pressure phenotypes in patients with hypertension and those with or without CKD. METHODS Participants aged 18 years and above who consented were recruited into the study. Anthropometric measurements including height, weight, and waist and hip circumferences were obtained, Office/clinic hypertension was defined as SBP =140mmHg and/or DBP =90mmHg or being on pharmacological treatment for hypertension. 24-hour ambulatory blood pressure monitoring were done. Obstructive sleep apnea was assessed using Stop Bang questionnaire. Estimated GFR was calculated using CKD-EPI Creatinine 2Equation and CKD was defined as eGFR<60ml/min/1.73m . RESULTS A total of three hundred and forty-nine (349) patients were enrolled for the study: 175 males and 174 females. Moderate to severe risk for obstructive sleep apnea (OSA) was observed in 51.4% of patients with CKD, 58.5% of hypertensive and 17.3% of apparently healthy participants. Male participants were more likely than female patients to have moderate and high OSA risk (41.7% vs 32.8%) and (10.3% vs 4.6%) respectively. Compared with other groups, CKD patients had the highest office and ambulatory blood pressure parameters; p<0.0001. CONCLUSION This study has demonstrated that obstructive sleep apnoea is prevalent among patients with chronic kidney disease and hypertension. Furthermore, the phenotypes of hypertension are accentuated in CKD and therefore, OSA may well be an important risk factor for CKD.

Abstract
Aims The aim of this study was to establish the diagnostic accuracy of culture of joint aspirate with and without saline injection-reaspiration. Patients and Methods This is a retrospective analysis of 580 hip and knee aspirations in patients who were deemed to have a moderate to high risk of infection, and who subsequently proceeded to revision arthroplasty over a period of 12 years. It was carried out at a large quaternary referral centre where preoperative aspiration is routine. Results Fluid was aspirated primarily in 313 (54%) cases and after saline injection-reaspiration of a 'dry tap' in 267 (46%) cases. Overall sensitivity and specificity of the diagnostic aspirate were 84% (78% to 89%) and 85% (81% to 88%), respectively. Sensitivity and specificity of saline injection-reaspiration after 'dry tap' were 87% (79% to 92%) and 79% (72% to 84%) compared with 81% (71% to 88%) and 90% (85% to 93%) for direct aspiration. Conclusion Preoperative joint aspiration and culture is a sensitive and specific test for the confirmation of diagnosis in patients at a moderate to high risk of prosthetic joint infection. Culture of saline injection-reaspiration also provides accurate diagnostic information in the event of a 'dry tap'. Both methods allow susceptibility testing of relevant organisms and are therefore able to guide perioperative antibiotic therapy. Cite this article: Bone Joint J 2018;100-B:749-54.

Can measures of physical performance in mid-life improve the clinical prediction of disability in early old age? Findings from a British birth cohort study. Exp Gerontol 2018; 110:118-124.

Abstract
BACKGROUND Poor performance in physical tests such as grip strength and walking speed is a risk factor for disability in old age, although whether such measures improve the discrimination of clinical prediction models when traditional clinical risk factors are already known is not clear. The prevalence of disability in mid-life is relatively low and hence screening in this age group may present an opportunity for early identification of those at increased future risk who may benefit most from preventative interventions. METHODS Data were drawn from two waves of the Medical Research Council National Survey of Health and Development. We examined whether several chronic conditions, poor health behaviours and lower scores on three measures of physical performance (grip strength, chair rise speed and standing balance time) at age 53 were associated with self-reported mobility and/or personal care disability at age 69. We used the area under the curve statistic (AUC) to assess model discrimination. RESULTS At age 69, 44% (826/1855) of participants reported mobility and/or personal care disability. Our final clinical prediction model included sex, knee osteoarthritis, taking 2+ medications, smoking, increased BMI and poor performance in all three physical tests, with an AUC of 0.740 compared with 0.708 for a model which did not include the performance measures. CONCLUSION Measures of physical performance in midlife improve discrimination in clinical prediction models for disability over 16 years. Importantly, these and similar measures are also potential targets of future diet, exercise and pharmacological intervention in mid-life.

Abstract
Measurement of the oxidation state of cytochrome c oxidase (oxCCO) can inform directly on neuronal metabolism. Conventionally this has been measured in vivo using benchtop broadband near infrared spectroscopy (NIRS) systems. Spatially resolved measures of oxCCO have recently been made possible using a multichannel fibre-based broadband NIRS system. We describe the use of a fibreless multiwavelength NIRS system using light emitting diodes (LED) designed specifically to image localised changes in oxCCO and hence neuronal metabolism. A fibreless system consisting of four modules, each containing two LED sources and four photodiode detectors, was developed. Each LED source contained eight LED dies (780, 811, 818, 842, 850, 882, 891 and 901 nm) assembled in an area of 1.5 × 1.5 mm. A well-established hyperoxia protocol was used to evaluate the oxCCO spatially resolved measurement capabilities of the system and, subsequently, its imaging capabilities were tested using a functional activation paradigm. A multi-spectral image reconstruction approach was used to provide images of Δ[HbO2], Δ[HHb] and Δ[oxCCO] from the multi-distance, multi-channel optical datasets. This novel fibreless multiwavelength NIRS system allows imaging of localised changes in oxCCO in the human brain, and has potential for development as an inexpensive, wearable, continuous monitor of cerebral energetics in a range of experimental and clinical scenarios.
