Significant association of MTHFD1 1958GA single nucleotide polymorphism with nonsyndromic cleft lip and palate in Indian population.

2014

Objectives: Nonsyndromic cleft lip and palate (NSCLP) is genetically distinct from those with syndromic clefts, and accounts for ~70% of cases with Oral clefts. Folate, or vitamin B9, is an essential nutrient in our diet. Allelic variants in genes involved in the folate pathway might be expected to have an impact on risk of oral clefts. Given the key role of methylenetetrahydrofolate dehydrogenase 1 (MTHFD1) in folate metabolism, it would be of significant interest to assess its role in NSCLP etiology. Study Design: The present study aims at examining the association between MTHFD1 1958G>A polymorphism and NSCLP risk by conducting a case-control study in south Indian population. Our sample …

Laboratory parameters in centenarians of Italian ancestry

2008

Studies aimed at collecting reference parameters for haematochemical analysis in the elderly are scarce and for the oldest old subjects even more rare. In order to establish the reference values for the most common laboratory text in long living individuals, we measured haematochemical parameters in >100 years old subjects and in aged subjects as control. Six hundred and two centenarians accepted to be enrolled in the study. A case history containing the complete anamnesis, clinical examinations, evaluation of the clinical cognitive and functional tests, was prepared for each centenarian. Blood samples from 120 > 100 years old subjects free of chronic or acute Illness (i.e. Alzheimer’s dise…

355 Night shift work and prostate cancer risk in a population-based case-control study in Spain

2013

Objectives Recent epidemiologic and animal data indicate that night work may increase the risk of cancer and specifically breast cancer. There is limited evidence on other hormone related cancers. We evaluated prostate cancer risk and night shift work in a population based case-control study in Spain, the MCC-Spain. Methods Incident prostate cancer cases (n = 1117) and randomly selected population controls (n = 1165) were enrolled in 7 regions of Spain. Lifetime occupational history including details on shift work, and information on lifestyle factors were assessed by face-to-face interviews. We estimated the risk of different shift profiles using unconditional logistic regression models ad…

Comparison of well-being of older adult choir singers and the general population in Finland: A case-control study

2016

Previous research suggests that singing in a choir as an older adult is associated with better quality of life (QOL). However, the degree to which sociodemographic variables and level of engagement in hobbies contribute to this relationship is largely unknown. The aim of the study was to compare quality of life (QOL) of older adult choir singers with a matched sample of older adults from the general population in Finland, taking into consideration sociodemographic variables, satisfaction with health, and level of engagement in hobbies. Case-control methods were used to match a sample of 109 older adult singers with a sample of 307 older adults from the general population. Tobit regression …

Sexual function, sexual activity, and quality of life in women with ovarian and endometrial cancer.

2013

5051 Background: Gynecological cancer (GC) is generally assumed to have an impact on sexual function and activity. Although there are several studies addressing the issue, case control studies are currently limited. Methods: We performed a cross-sectional investigation of sexual function and activity utilizing the sexual activity questionnaire, the female sexual function index, and parts of the EORTC QLQ C30. Patients with gynecological cancer (GC) like ovarian and endometrial cancer were compared with a control group (C) of non-cancer patients. Inclusion of GC was only allowed if treatment was completed ≥12 months previously and patients were disease-free. Results: The questionnaires were…

Congenital anomalies among live births in a high environmental risk area—A case-control study in Brindisi (southern Italy)

2013

Maternal exposure to ambient pollution has been increasingly linked to the risk of congenital anomalies (CAs) in the fetus and newborns. Recently, a descriptive study in the high environmental risk city of Brindisi (Italy) revealed an increased prevalence of total CAs, especially congenital heart disease (CHD) and ventricular septal defects (VSDs), both at the local level and in comparison with the pool of EUROCAT registries. This paper concerns a population-based case control study to investigate the association between maternal exposure to air pollutants - sulfur dioxide (SO2) and total suspended particulate (TSP) matter - and the risk of CA. Cases were newborns up to 28 days of age, born…
