Prevalence of Cataract in an Older Population in India
2011
Purpose To describe the prevalence of cataract in older people in 2 areas of north and south India. Design Population-based, cross-sectional study. Participants Randomly sampled villages were enumerated to identify people aged ≥60 years. Of 7518 enumerated people, 78% participated in a hospital-based ophthalmic examination. Methods The examination included visual acuity measurement, dilatation, and anterior and posterior segment examination. Digital images of the lens were taken and graded by type and severity of opacity using the Lens Opacity Classification System III (LOCS III). Main Outcome Measures Age- and gender-standardized prevalence of cataract and 95% confidence intervals (CIs). W…
Association Between Short Physical Performance Battery and Falls in Older People: The Progetto Veneto Anziani Study.
2014
It is known that weakness in the lower limbs is associated with recurrent falls in old people. Among the tests routinely used to assess lower extremity strength, the Short Physical Performance Battery (SPPB) is one of those used most often, but its relationship with recurrent falls is poorly investigated. We aimed to determine if SPPB scores are related to recurrent falling in a sample of 2710 older-aged people, and to ascertain which test in the SPPB is most strongly associated with a higher rate of falls. In this cross-sectional study, we demonstrated that participants scoring 0-6 in the SPPB were more likely to be recurrent fallers than those scoring 10-12 (odds ratio [OR]=3.46, 95% conf…
Serum 25-Hydroxyvitamin D and Orthostatic Hypotension in Old People
2014
Interest in the association between serum 25-hydroxyvitamin D (25OHD) and blood pressure has increased because recent research showed a close relationship between them, but there is still little information on the possible association between 25OHD and orthostatic hypotension. The aim of this study was to explore the relationship of 25OHD levels with any presence of orthostatic hypotension in a large group of older people. This study was part of the Progetto Veneto Anziani (Pro.V.A.), an Italian population–based cohort study involving people aged >65 years. In this cross-sectional work, we considered 2640 (1081 men and 1559 women) with a mean age of 73.8±6.8 years. Orthostatic hypotensi…
The effect of body mass index, lower extremity performance, and use of a private car on incident life-space restriction: a two-year follow-up study
2018
Background: The purpose of the study was to explore the single and combined contributions of body mass index (BMI) and lower extremity performance as modifiable physical factors, and the influence of use of a private car as an environmental factor on prevalent and incident life-space restriction in community-dwelling older people. Methods: Community-dwelling people aged 75–90 years (n = 823) participated in the Life-Space Mobility in Old Age (LISPE) two-year follow-up study. Participants who reported that the largest life-space area they had attained, without aid from any device or another person, was the neighborhood or less were considered to have life-space restriction. Incident life-spa…
Choice and Outcomes of Rate Control versus Rhythm Control in Elderly Patients with Atrial Fibrillation: A Report from the REPOSI Study
2018
Background: Among rate-control or rhythm-control strategies, there is conflicting evidence as to which is the best management approach for non-valvular atrial fibrillation (AF) in elderly patients. Design: We performed an ancillary analysis from the ‘Registro Politerapie SIMI’ study, enrolling elderly inpatients from internal medicine and geriatric wards. Methods: We considered patients enrolled from 2008 to 2014 with an AF diagnosis at admission, treated with a rate-control-only or rhythm-control-only strategy. Results: Among 1114 patients, 241 (21.6%) were managed with observation only and 122 (11%) were managed with both the rate- and rhythm-control approaches. Of the remaining 751 patie…
Relationship between physical activity and physical performance in later life in different birth weight groups.
2017
There is strong evidence that physical activity (PA) has an influence on physical performance in later life. Also, a small body size at birth has been associated with lower physical functioning in older age and both small and high birth weight have shown to be associated with lower leisure time physical activity. However, it is unknown whether size at birth modulates the association between PA and physical performance in old age. We examined 695 individuals from the Helsinki Birth Cohort Study born in Helsinki, Finland between 1934 and 1944. At a mean age of 70.7 years PA was objectively assessed with a multisensory activity monitor and physical performance with the Senior Fitness Test (SFT…
Hospital Contacts for Psychiatric Disorders in Parents of Children With Cancer in Denmark
2021
Abstract Background Having a child diagnosed with cancer is a devastating experience that may affect parents’ mental health. We aimed to assess the risk of hospital contacts for psychiatric disorders in parents of children with cancer. Methods We conducted a nationwide population-based cohort study using Danish registry data. Parents of children diagnosed with cancer between 1982 and 2014 (n = 6689 mothers, n = 5509 fathers) were matched with comparison parents of cancer-free children (n = 67 544 mothers, n = 55 756 fathers). We used Cox proportional hazards models to estimate the risk of hospital contacts for any psychiatric disorder and specific disorders. Cox models were also used to inv…
FOLFIRINOX as induction treatment in rectal cancer patients with synchronous metastases: Results of the FFCD 1102 phase II trial
2018
Abstract Aim of the study The optimal therapeutic strategy in patients with rectal cancer and synchronous unresectable metastases remains unknown. We evaluated the efficacy of FOLFIRINOX induction therapy in this setting. Patients and methods Chemotherapy-naive patients received at least 8 cycles of FOLFIRINOX. The primary end-point was the 4-month disease control (4 m DC) rate. Tumour responses were centrally reviewed and assessed by computed tomography scan for metastases (Response Evaluation Criteria in Solid Tumours criteria) and magnetic resonance imaging for rectal tumorus. With a Simon 2-stage design and a targeted (H1) 4 m DC > 75%, 65 patients were enrolled from July 2012 to Februa…
Early deaths from childhood cancer in Germany 1980-2016
2020
Abstract Background Even though the survival of childhood cancer has improved over the last decades, there are still children dying shortly after diagnosis. The aim of the study is to add to understanding of the reasons for deaths shortly after date of diagnosis. Methods Using data of the population-based German Childhood Cancer Registry (cancer below 15 years of age diagnosed between 1980 and 2016), we compared characteristics of 671 children with cancer who died within 30 days of diagnosis to 53,649 patients with childhood cancer who survived longer. In addition to a descriptive analysis, we used logistic regression with multivariable fractional polynomials to describe the relationship be…
Childhood acute lymphoblastic leukaemia and birthweight: Insights from a pooled analysis of case–control data from Germany, the United Kingdom and th…
2012
Abstract Background Heavy birthweight is one of the few established risk factors for childhood acute lymphoblastic leukaemia (ALL). To provide new insight into this relationship, particularly at the extremes ( 4500 g), we pooled data from three of the largest childhood cancer case–control studies ever conducted. Methods Birthweight and gestational age on 4075 children with ALL and 12,065 controls were collected during the course of three studies conducted in the USA, the UK and Germany in the 1990s. Information was obtained from mothers at interview, and the impact of bias was evaluated using the UK study which accessed birth registrations of participants and non-participants. Odds ratios (…
