Abstract STUDY QUESTION Do young women with early ovarian ageing (EOA), defined as unexplained, and repeatedly few oocytes harvested in ART have an increased risk of age-related events? SUMMARY ANSWER At follow-up, women with idiopathic EOA had an increased risk of age-related events compared to women with normal ovarian ageing (NOA). WHAT IS KNOWN ALREADY Early and premature menopause is associated with an increased risk of cardiovascular diseases (CVDs), osteoporosis and death. In young women, repeated harvest of few oocytes in well-stimulated ART cycles is a likely predictor of advanced menopausal age and may thus serve as an early marker of accelerated general ageing. STUDY DESIGN, SIZE, DURATION A register-based national, historical cohort study. Young women (≤37 years) having their first ART treatment in a public or private fertility clinic during the period 1995–2014 were divided into two groups depending on ovarian reserve status: EOA (n = 1222) and NOA (n = 16 385). Several national registers were applied to assess morbidity and mortality. PARTICIPANTS/MATERIALS, SETTING, METHODS EOA was defined as ≤5 oocytes harvested in a minimum of two FSH-stimulated cycles and NOA as ≥8 oocytes in at least one cycle. Cases with known causes influencing the ovarian reserve (endometriosis, ovarian surgery, polycystic ovary syndrome, chemotherapy etc.) were excluded. To investigate for early signs of ageing, primary outcome was an overall risk of ageing-related events, defined as a diagnosis of either CVD, osteoporosis, type 2 diabetes, cancer, cataract, Alzheimer’s or Parkinson’s disease, by death of any-cause as well as a Charlson comorbidity index score of ≥1 or by registration of early retirement benefit. Cox regression models were used to assess the risk of these events. Exposure status was defined 1 year after the first ART cycle to assure reliable classification, and time-to-event was measured from that time point. MAIN RESULTS AND THE ROLE OF CHANCE Median follow-up time from baseline to first event was 4.9 years (10/90 percentile 0.7/11.8) and 6.4 years (1.1/13.3) in the EOA and NOA group, respectively. Women with EOA had an increased risk of ageing-related events when compared to women with a normal oocyte yield (adjusted hazard ratio 1.24, 95% CI 1.08 to 1.43). Stratifying on categories, the EOA group had a significantly increased risk for CVD (1.44, 1.19 to 1.75) and osteoporosis (2.45, 1.59 to 3.90). Charlson comorbidity index (1.15, 0.93 to 1.41) and early retirement benefit (1.21, 0.80 to 1.83) was also increased, although not reaching statistical significance. LIMITATIONS, REASONS FOR CAUTION Cycles never reaching oocyte aspiration were left out of account in the inclusion process and we may therefore have missed women with the most severe forms of EOA. We had no information on the total doses of gonadotrophin administered in each cycle. WIDER IMPLICATIONS OF THE FINDINGS These findings indicate that oocyte yield may serve as marker of later accelerated ageing when, unexpectedly, repeatedly few oocytes are harvested in young women. Counselling on life-style factors as a prophylactic effort against cardiovascular and other age-related diseases may be essential for this group of women. STUDY FUNDING/COMPETING INTEREST(S) No external funding was received for this study. All authors declare no conflict of interest. TRIAL REGISTRATION NUMBER N/A

Habitual consumption of dairy products has been shown to play an important role in the prevention of several chronic diseases. We aimed to prospectively assess the relationship between the change in dairy product consumption (both regular fat and low/reduced fat) and the 15-year incidence of age-related macular degeneration (AMD). In the Blue Mountains Eye Study, 2037 participants aged 49 years or above at baseline were re-examined at follow-up in 1997–9, 2002–4 and/or 2007–9. AMD was assessed from retinal photographs. Dietary data were collected using a semi-quantitative FFQ, and servings of dairy product consumption calculated. Over the 15-year follow-up, there were 352, 268 and eighty-four incident cases of any, early and late AMD, respectively. After adjusting for age, sex, current smoking, white cell count and fish consumption, a significant linear trend (Pfor trend = 0·003) was observed with decreasing consumption of total dairy foods and the 15-year incidence of late AMD, comparing the lowestv.highest quintile of intake (OR 2·80, 95 % CI 1·21, 3·04). Over the 15 years, decreased consumption of reduced-fat dairy foods was associated with an increased risk of incident late AMD, comparing the lowest to highest quintile of intake (OR 3·10, 95 % CI 1·18, 8·14,Pfor trend = 0·04). Decreasing total dietary Ca intake over the 15 years was also associated with an increased risk of developing incident late AMD (multivariable-adjustedPfor trend = 0·03). A lower consumption of dairy products (regular and low fat) and Ca was independently associated with a higher risk of developing incident late AMD in the long term. Additional cohort studies are needed to confirm these findings.

Introduction: This study aims to assess the correlation of the age-adjusted Charlson comorbidity index (ACCI) with 5-year mortality in a surgically treated hip fracture population. Materials and Methods: A retrospective analysis was performed on 1057 patients aged 60 years and above who underwent surgery for hip fracture with a minimum of 5-year follow-up (92.2% 5-year follow-up rate) in a tertiary hospital. Manual review of patients’ electronic hospital records was performed to record demographic data, comorbidities, and length of stay. Mortality data were extracted from the hospital’s electronic medical records and corroborated with the National Electronic Health Record. Results: Of the 1057 patients, 283 (26.8%) were male. The majority of patients were 80 years of age and above (42.5%), with the oldest patient operated on age 102 with a mean age of 77.8 (8.6) years. Four hundred eighteen (39.5%) patients sustained extracapsular intertrochanteric fractures. The mean follow-up duration was 8 years and 3 days with an overall survivorship of 37.2%. A multiple regression model constructed with ACCI, age, gender, and fracture pattern demonstrated satisfactory predictive ability with a concordance statistic of 0.68. Patients with a higher ACCI category (≥6) had an increased 5-year mortality rate (41.8%) with an odds ratio of 13.6 (6.7-31.8, P < .001) compared to those with an ACCI category of 3 and below (89.3%). Discussion: The study demonstrates that ACCI correlated with 5-year mortality after surgical treatment of hip fracture. This information is pertinent in the counseling of patients with regard to their midterm survival following hip fracture surgery and may inform policy makers of the varied midterm survival rates in patients with differing ACCI scores and educate the allocation of health-care resources. Conclusion: The ACCI correlates with 5-year mortality after surgical treatment of hip fracture.

Abstract Background: In potentially severe diseases in general and COVID-19 in particular, it is vital to early identify those patients who are going to develop complications. The last update of a recent living systematic review dedicated to predictive models in COVID-19,[1] critically appraises 145 models, 8 of them focused on prediction of severe disease and 23 on mortality. Unfortunately, in all 145 models, they found a risk of bias significant enough to finally "not recommend any for clinical use". Authors suggest concentrating on avoiding biases in sampling and prioritising the study of already identified predictive factors, rather than the identification of new ones that are often dependent on the database. Our objective is to develop a model to predict which patients with COVID-19 pneumonia are at high risk of developing severe illness or dying, using basic and validated clinical tools.Methods: prospective cohort of consecutive patients admitted in a teaching hospital during the “first wave” of the COVID-19 pandemic. Follow-up to discharge from hospital. Multiple logistic regression selecting variables according to clinical and statistical criteria. Results: 404 consecutive patients were evaluated, 392 (97%) completed follow-up. Mean age was 61 years; 59% were men. The median burden of comorbidity was 2 points in the Age-adjusted Charlson Comorbidity Index, CRB was abnormal in 18% of patients and basal oxygen saturation on admission lower than 90% in 18%. A model composed of Age-adjusted Charlson Comorbidity Index, CRB score and basal oxygen saturation can predict unfavorable evolution or death with an area under the ROC curve of 0.85 (95% CI: 0.80-0.89), and 0.90 (95% CI: 0.86 to 0.94), respectively.Conclusion: prognosis of COVID-19 pneumonia can be predicted in the out-of-hospital environment using two classic prognostic scales and a pocket pulse oximeter.

AimsTo examine independent and interactive associations of ophthalmic and systemic conditions with incident dementia.MethodsOur analysis included 12 364 adults aged 55–73 years from the UK Biobank cohort. Participants were assessed between 2006 and 2010 at baseline and were followed up until the early of 2021. Incident dementia was ascertained using hospital inpatient, death records and self-reported data.ResultsOver 1 263 513 person-years of follow-up, 2304 cases of incident dementia were documented. The multivariable-adjusted HRs (95% CI) for dementia associated with age-related macular degeneration (AMD), cataract, diabetes-related eye disease (DRED) and glaucoma at baseline were 1.26 (1.05 to 1.52), 1.11 (1.00 to 1.24), 1.61 (1.30 to 2.00) and (1.07 (0.92 to 1.25), respectively. Diabetes, heart disease, stroke and depression at baseline were all associated with an increased risk of dementia. Of the combination of AMD and a systemic condition, AMD-diabetes was associated with the highest risk for incident dementia (HR (95% CI): 2.73 (1.79 to 4.17)). Individuals with cataract and a systemic condition were 1.19–2.29 times more likely to develop dementia compared with those without cataract and systemic conditions. The corresponding number for DRED and a systemic condition was 1.50–3.24. Diabetes, hypertension, heart disease, depression and stroke newly identified during follow-up mediated the association between cataract and incident dementia as well as the association between DRED and incident dementia.ConclusionsAMD, cataract and DRED but not glaucoma are associated with an increased risk of dementia. Individuals with both ophthalmic and systemic conditions are at higher risk of dementia compared with those with an ophthalmic or systemic condition only.

Abstract BACKGROUND: Women who are survivors of Hodgkin’s Lymphoma (HL) are at increased risk of developing breast cancer (BCa) as a long-term complication due to the use of extended field (mantle) irradiation (RT) of disease above the diaphragm. Many young women are at significantly increased risk of BCa prior to the age at which routine screening mammography is recommended for the general population. The sensitivity of mammography is lower in these women, in part due to increased breast tissue density characteristic of young pre-menopausal women. Currently, there is a paucity of information on the optimal screening modality and surveillance frequency for these women. METHODS: We reviewed the current BCa screening strategies used for this high risk group at our centre and described the incidence, method of detection, and characteristics of secondary BCas in a cohort of 115 women who received supradiaphragmatic RT for HL before age 30 between 1965 and 2000 at Princess Margaret Hospital (PMH) and who subsequently accepted long-term follow-up in a high-risk screening clinic. RESULTS: Median age at treatment was 22 (range 9–30). Radiation fields were mantle in 106 women, modified mantle in 6, and involved field in 3 (median dose delivered: 35 Gy, range 15–60). RT alone was used for 44 patients while 71 received combined modality therapy, of which 45 (65%) received MOPP. Treatment induced amenorrhea occurred in 15 women (median age 38); hormone replacement therapy was subsequently used by 9. Of the 107 women who participated in annual radiographic BCa screening, 95 were screened with mammogram alone, 1 with breast MRI alone, 8 with mammogram and MRI, and 3 with mammogram and ultrasound. Median age at first mammogram was 36; however, median age decreased with more recent year of HL diagnosis (age 40 for women diagnosed before 1985 compared to age 33 for women diagnosed after 1985, p<0.0001). Women with high breast density received MRI screening more often (p=0.02); however, breast density was not significantly associated with previous breast radiation dose or age at last follow-up. Twelve women were diagnosed with BCa in this cohort, following active breast surveillance for a median of 5 years (representing 584 person-years). The 20-year cumulative incidence of breast cancer was 10.9% (95% CI 5.3–18.8%) in this group of women. This was comparable to the 20-year cumulative incidence of breast cancer of 12% (95% CI 8–17%) in all 448 women with HL treated with supradiaphragmatic radiation before age 30 at PMH during the same time period. BCa occurred after a median of 17 years after treatment for HL (range 13–28). Median age at BCa diagnosis was 40 (range 31–51). Seven cancers were detected by physical exam (6 node-positive invasive BCas, 1 in-situ BCa) and 5 were detected on annual mammograms (1 node-positive invasive BCa, 4 in-situ BCas). CONCLUSIONS: Although women in the more recent treatment cohort are receiving their first mammogram at a younger age, the majority of BCas were still detected clinically, and these BCas had less favorable pathological characteristics. More frequent breast imaging should be considered in women who have had supradiaphragmatic RT for HL. Prospective evaluation of breast MRI as a screening strategy for HL survivors has been initiated at PMH in an effort to detect BCa at an earlier stage.

114 Background: Life expectancy is very essential in deciding treatment options in men with prostate cancer (PCa); however, the impact of comorbidities on outcomes is not well-established. We investigated the influence of Charlson Comorbidity Index (CCI) on survival endpoints in men with localized PCa who were treated with prostate radiotherapy (RT). Methods: Men with intermediate and high risk PCa who were treated with definitive RT between 1/2007 and 12/2012 were included. Groups were created according to their baseline CCI score at diagnosis into no, mild and severe comorbidity (CCI 0, 1 or 2+). The groups were then compared based on patients’ characteristics and prognostic factors. Kaplan-Meier curves and Uni/multivariate analyses (MVA) were used to examine the impact of CCI groups on overall (OS), disease specific (DSS), and biochemical relapse free (BRFS) survival. Results: 257 patients were identified after excluding low risk, metastatic cases and those with inadequate follow up. Median follow-up was 92 months (range: 2-135) and median age was 73 years (range: 48-85). 53% of the cases were black and 67% were of intermediate risk. Median RT dose was 76 Gy and 47% received androgen deprivation therapy. CCI groups 0, 1 and 2+ encompassed 76 (30%), 54 (21%) and 127 (49%) patients, respectively. Groups were generally well-balanced. 10 and 15 years OS was significantly different across CCI groups (76% & 53%, 46% & 31% and 55% & 14%, for CCI-0, 1 and 2+ respectively; p < 0.001). CCI-0 had better DSS than CCI-2+ ( p = 0.03) with no difference for CCI-0 vs 1 ( p = 0.1). BRFS was non-different among CCI groups ( p = 0.99). On MVA, increased CCI was deterministic for OS ( p < 0.001) after adjusting for age, Gleason’s score and T-stage. For DSS, only age and T3 vs T1/2 were independently prognostic ( p < 0.001); whereas CCI-1 vs 0 was only marginal ( p = 0.05). Conclusions: Higher CCI was a significant predictor of shorter OS in intermediate and high-risk PCa. Baseline comorbidities should be taken into consideration during patient counselling for treatment options and in designing prospective trials for men with localized prostate cancer.

Introduction: Renal transplant experiences widespread success, but little is published regarding the postoperative complications. The Charlson Comorbidity Index (CCI) is a system of mortality risk assessment. Our purpose is to assess the 90-day postoperative complications after renal transplantation. The secondary objective is to clarify whether CCI predicts complications. We hypothesized increased CCI corresponds to worse complication on the Clavien scale.Methods: This is a retrospective analysis of renal recipients at our institution (2011‒2013) who were ≥18 years old and received complete follow up. CCI, age, gender, body mass index (BMI), and graft type were extracted from the electronic medical records. Complications were scored using the Clavien scale. Descriptive statistics and logistic regression were used to analyze 198 patients.Results: The mean age was 53 (standard deviation [SD] 14), mean BMI 27.4 (SD 14), median CCI 1. Grade 2 or higher (significant) complications occurred in 60% of patients and Grade 3b or higher (severe) in 15% of patients in the 90-day postoperative period. Sixty-eight different complications were identified, the most common being blood transfusion (19%). Logistic regression suggests a predictive value of CCI (odds ratio [OR] 1.70; 95% confidence interval [CI] 1.3‒2.3) for severe complications, with diabetes mellitus and peripheral vascular disease conferring increased risk. Conclusions: Renal transplant carries significant risk. This data can be used to improve patient counselling on the likely postoperative course. Study limitations include the retrospective design, predisposing to potential bias in data capture.

Background. C-reactive protein (CRP) is one of the most common oxidative indexes affected by many diseases. In recent years, there have been many studies on CRP, but the relationship between CRP levels and the cardiovascular risk in the Chinese young female population is still unclear. The purpose of this work is to explore the predictive value of CRP for the cardiovascular risk in the Chinese young female population. Methods. The study is conducted by 1 : 1 case-control to retrospectively analyze 420 young women with acute coronary syndrome (ACS group) who underwent percutaneous coronary intervention (PCI) and 420 young women (control group) who underwent coronary angiography (CAG) to exclude coronary heart disease from January 2007 to December 2016. All patients are divided into three subgroups according to CRP values: subgroup 1: CRP < 1.0   mg / L ( n = 402 ); subgroup 2: 1.0   mg / L ≤ CRP ≤ 3.0   mg / L ( n = 303 ); subgroup 3: CRP > 3.0   mg / L ( n = 135 ). The levels of CRP were observed in the two groups and three subgroups. Results. A total of 840 patients were analyzed. The mean duration of follow-up was 66.37 ± 30.06 months. The results showed that the level of CRP in the ACS group was significantly higher than that in the control group ( 1.30 ± 1.70 vs. 3.33 ± 5.92 , respectively, p < 0.001 ), and patients with higher CRP levels were associated with a significantly increased rate of major adverse cardiovascular events (MACE) (7.0% vs. 8.9% vs. 19.30%, respectively, p < 0.05 ). After adjustment for baseline covariates, CRP level was still an independent predictor for the incidence of MACE, either as a continuous variable or as a categorical variable. There was a significantly higher rate of all-cause mortality and myocardial infarction in patients with higher CRP values during follow-up. Conclusions. The research results show that high CRP is associated with increased risk of ACS in the Chinese young female population. Risk stratification with CRP as an adjunct to predict clinical risk factors might be useful in the Chinese young female population.

Abstract Background This study aimed to investigate the risk of Parkinson’s disease (PD) among patients with age-related macular degeneration (AMD) and its association with confounding comorbidities. Methods A population-based retrospective cohort study was conducted using Longitudinal Health Insurance Database 2000 (LHID2000). We established AMD and non-AMD cohorts from January 1, 2000 to December 31, 2012 to determine the diagnosis of PD. A total of 20,848 patients were enrolled, with 10,424 AMD patients and 10,424 controls matched for age, sex, and index year at a 1:1 ratio. The follow-up period was from the index date of AMD diagnosis to the diagnosis of PD, death, withdrawal from the insurance program, or end of 2013. Multivariable Cox regression analysis was performed to examine the hazard ratio (HR) and 95% confidence interval (CI) for the risk of PD between the AMD and non-AMD cohorts. Result After adjusting for potential confounders, there was a higher risk of developing PD in the AMD cohort than in the non-AMD cohort (adjusted HR = 1.35, 95% CI = 1.16–1.58). A significant association could be observed in both female (aHR = 1.42, 95% CI = 1.13–1.80) and male (aHR = 1.28, 95% CI = 1.05–1.57) patients, aged more than 60 years (60–69: aHR = 1.51, 95% CI = 1.09–2.09, 70–79: aHR = 1.30, 95% CI = 1.05–1.60; 80–100: aHR = 1.40, 95% CI = 1.01–1.95), and with more than one comorbidity (aHR = 1.40, 95% CI = 1.20–1.64). A significant association between increased risk of PD and AMD was observed among patients with comorbidities of osteoporosis (aHR = 1.68, 95% CI = 1.22–2.33), diabetes (aHR = 1.41, 95% CI = 1.12–1.78) and hypertension (aHR = 1.36, 95% CI = 1.15–1.62) and medications of statin (aHR = 1.42, 95% CI = 1.19–1.69) and calcium channel blocker (CCB) (aHR = 1.32, 95% CI = 1.11–1.58). The cumulative incidence of PD was significantly higher over the 12-year follow-up period in AMD cohort (log-rank test, p < 0.001). Conclusions Patients with AMD may exhibit a higher risk of PD than those without AMD.

215 Background: Comorbidities significantly influence how physicians approach the treatment of prostate cancer and should be evaluated prior to the prostate biopsy. The Total Illness Burden Index for Prostate Cancer (TIBI-CaP) patient questionnaire and Charlson Comorbidity Index (CCI) usually calculated by the physician, may provide information on competing risks but have not been compared prospectively. Methods: A prospective observational cohort study was performed of 133 participants prior to obtaining a transrectal ultrasound guided prostate biopsy. Eleven patients had incomplete data or missing follow-up; therefore, a total of 122 (92%) patients were retained for a mean of 21 months (range 4 – 31 months). The TIBI-CaP and CCI scores were compared between subgroups defined by non-elective hospital admission, elective surgery, non-prostate malignancy and survival status using t-tests. Results: Patients averaged 64.5 years at enrollment. One patient died in the study from a metastatic sarcoma. The overall hospital admission rate was 17% (21/122), most commonly from cardiovascular or pulmonary complications. Forty-six men (38%) were diagnosed with cancer on the prostate biopsy. The most common treatments were prostatectomy (39%), active surveillance (26%), or external beam radiation therapy (20%). Twenty-three percent (28/122) had elective surgery and 5% (6/122) were diagnosed with a non-prostate malignancy. Mean TIBI-CaP scores were higher in men who were admitted to the hospital (5.1 vs. 3.5, p=0.03), had elective surgery (4.8 vs. 3.4, p=0.05) or non-prostate cancer (5.5 vs 3.7, p=0.17). No significant differences were observed in CCI scores In stepwise logistic regression, a TIBI-CaP score > 5.0 was associated with 3.5 times higher risk for hospital admission (95% CI: 1.3–10.0, p=0.02). Conclusions: The patient-reported measure of comorbidity (TIBI-CaP) identified patients at high risk for non-elective hospital admission over at 20 month average follow up period and may aid medical decision making specifically in the prostate biopsy population better than that of the Charlson Comorbidity Index.
