Cardiovascular disease in insulin dependent diabetes mellitus: similar rates but different risk factors in the US compared with Europe. (1/5966)

BACKGROUND: Cardiovascular disease (CVD) in insulin dependent diabetes mellitus (IDDM) has been linked to renal disease. However, little is known concerning international variation in the correlations with hyperglycaemia and standard CVD risk factors. METHODS: A cross-sectional comparison was made of prevalence rates and risk factor associations in two large studies of IDDM subjects: the Pittsburgh Epidemiology of Diabetes Complications Study (EDC) and the EURODIAB IDDM Complications Study from 31 centres in Europe. Subgroups of each were chosen to be comparable by age and duration of diabetes. The EDC population comprises 286 men (mean duration 20.1 years) and 281 women (mean duration 19.9 years); EURODIAB 608 men (mean duration 18.1 years) and 607 women (mean duration 18.9 years). The mean age of both populations was 28 years. Cardiovascular disease was defined by a past medical history of myocardial infarction, angina, and/or the Minnesota ECG codes (1.1-1.3, 4.1-4.3, 5.1-5.3, 7.1). RESULTS: Overall prevalence of CVD was similar in the two populations (i.e. men 8.6% versus 8.0%, women 7.4% versus 8.5%, EURODIAB versus EDC respectively), although EDC women had a higher prevalence of angina (3.9% versus 0.5%, P < 0.001). Multivariate modelling suggests that glycaemic control (HbA1c) is not related to CVD in men. Age and high density lipoprotein cholesterol predict CVD in EURODIAB, while triglycerides and hypertension predict CVD in EDC. For women in both populations, age and hypertension (or renal disease) are independent predictors. HbA1c is also an independent predictor-inversely in EURODIAB women (P < 0.008) and positively in EDC women (P = 0.03). Renal disease was more strongly linked to CVD in EDC than in EURODIAB. CONCLUSIONS: Despite a similar prevalence of CVD, risk factor associations appear to differ in the two study populations. Glycaemic control (HbA1c) does not show a consistent or strong relationship to CVD.  (+info)

Hereditary juvenile haemochromatosis: a genetically heterogeneous life-threatening iron-storage disease. (2/5966)

Juvenile haemochromatosis is a rare inborn error of iron metabolism with clinical manifestations before 30 years of age. Unlike adult haemochromatosis which principally affects men, juvenile haemochromatosis affects the sexes equally; it causes early endocrine failure, dilated cardiomyopathy and joint disease. We report four patients (two of each sex) from three pedigrees affected by juvenile haemochromatosis with a mean onset at 22 years (range 14-30). All had endocrine deficiency with postpubertal gonadal failure secondary to pituitary disease; two suffered near-fatal cardiomyopathy with heart failure. Mean time to diagnosis from the first clinical signs of disease was 9.8 years (range 0.5-20) but general health and parameters of iron storage responded favourably to iron-depletion therapy. A 24-year-old man listed for heart transplantation because of cardiomyopathy [left ventricular (LV) ejection fraction 16%] responded to intravenous iron chelation with desferrioxamine combined with phlebotomy (ejection fraction 31%). A 27-year-old woman with subacute biventricular heart failure refractory to medication required orthotopic cardiac transplantation before the diagnosis was established (LV ejection fraction 25%). Genetic studies showed that these two patients with cardiomyopathy from unrelated families were heterozygous for the HFE 845G-->A (C282Y) mutation and wild-type at the H63D locus: complete sequencing of the intron-exon boundaries and entire coding sequence of the HFE gene failed to identify additional lesions. Two siblings in a pedigree without cardiomyopathy were wild-type at the HFE C282Y locus; although the brother harboured a single copy of the 187C-->G (H63D) allele, segregation analysis showed that in neither sibling was the iron-storage disease linked to MHC Class I markers on chromosome 6p. Juvenile haemochromatosis is thus a genetically heterogenous disorder distinct from the common adult variant.  (+info)

Constitutional genetic variation at the human aromatase gene (Cyp19) and breast cancer risk. (3/5966)

The activity of the aromatase enzyme, which converts androgens into oestrogens and has a major role in regulating oestrogen levels in the breast, is thought to be a contributing factor in the development of breast cancer. We undertook this study to assess the role of constitutional genetic variation in the human aromatase gene (Cyp19) in the development of this disease. Our genotyping of 348 cases with breast cancer and 145 controls (all Caucasian women) for a published tetranucleotide repeat polymorphism at intron 4 of the Cyp19 gene revealed the presence of six common and two rare alleles. Contingency table analysis revealed a significant difference in allelic distribution between cases and controls (chi2 5df = 13.52, P = 0.019). The allele measuring 171 bp was over-represented in cases; of 14 individuals homozygous for this allele, 13 were cases. These individuals had a higher incidence of cancer in family members and an earlier age at diagnosis than other cases. In sequencing Cyp19's coding exons and regulatory regions, we discovered a perfect association between a silent polymorphism (G-->A at Val80) and the high-risk genotype. Our conclusion is that constitutional genetic variation at the Cyp19 locus is associated with the risk of developing breast cancer, with the 171-bp allele serving as the high-risk allele.  (+info)

Cancer risk in close relatives of women with early-onset breast cancer--a population-based incidence study. (4/5966)

Inherited susceptibility to breast cancer is associated with an early onset and bilateral disease. The extent of familial risks has not, however, been fully assessed in population-based incidence studies. The purpose of the study was to quantify the risks for cancers of the breast, ovary and other sites of close relatives of women in whom breast cancer was diagnosed at an early age. Records collected between 1943 and 1990 at the Danish Cancer Registry were searched, and 2860 women were found in whom breast cancer was diagnosed before age 40. Population registers and parish records were used to identify 14 973 parents, siblings and offspring of these women. Cancer occurrence through to 31 December 1993 was determined within the Cancer Registry's files and compared with national incidence rates. Women with early-onset breast cancer were at a nearly fourfold increased risk of developing a new cancer later in life (268 observed vs. 68.9 expected). The excess risk was most evident for second cancer of the breast (181 vs. 24.5) and for ovarian cancer (20 vs. 3.3). For mothers and sisters, risks for cancers of the breast and ovary were significantly increased by two- to threefold. Bilateral breast cancer and breast-ovarian cancer were very strong predictors of familial risks, with one in four female relatives predicted to develop breast and/or ovarian cancer by age 75. Mothers had a slightly increased risk of colon cancer, but not endometrial cancer. The risk for breast cancer was also increased among fathers (standardized incidence ratio 2.5; 95% CI 0.5-7.4) and especially brothers (29; 7.7-74), although based on small numbers. The risk for prostatic cancer was unremarkable. In this large population-based survey, the first-degree relatives of women who developed breast cancer before age 40 were prone to ovarian cancer as well as male and female breast cancer, but not other tumours that may share susceptibility genes with breast cancer.  (+info)

Age of onset in Huntington disease: sex specific influence of apolipoprotein E genotype and normal CAG repeat length. (5/5966)

Age of onset (AO) of Huntington disease (HD) is known to be correlated with the length of an expanded CAG repeat in the HD gene. Apolipoprotein E (APOE) genotype, in turn, is known to influence AO in Alzheimer disease, rendering the APOE gene a likely candidate to affect AO in other neurological diseases too. We therefore determined APOE genotype and normal CAG repeat length in the HD gene for 138 HD patients who were previously analysed with respect to CAG repeat length. Genotyping for APOE was performed blind to clinical information. In addition to highlighting the effect of the normal repeat length upon AO in maternally inherited HD and in male patients, we show that the APOE epsilon2epsilon3 genotype is associated with significantly earlier AO in males than in females. Such a sex difference in AO was not apparent for any of the other APOE genotypes. Our findings suggest that subtle differences in the course of the neurodegeneration in HD may allow interacting genes to exert gender specific effects upon AO.  (+info)

Multipoint oligogenic analysis of age-at-onset data with applications to Alzheimer disease pedigrees. (6/5966)

It is usually difficult to localize genes that cause diseases with late ages at onset. These diseases frequently exhibit complex modes of inheritance, and only recent generations are available to be genotyped and phenotyped. In this situation, multipoint analysis using traditional exact linkage analysis methods, with many markers and full pedigree information, is a computationally intractable problem. Fortunately, Monte Carlo Markov chain sampling provides a tool to address this issue. By treating age at onset as a right-censored quantitative trait, we expand the methods used by Heath (1997) and illustrate them using an Alzheimer disease (AD) data set. This approach estimates the number, sizes, allele frequencies, and positions of quantitative trait loci (QTLs). In this simultaneous multipoint linkage and segregation analysis method, the QTLs are assumed to be diallelic and to interact additively. In the AD data set, we were able to localize correctly, quickly, and accurately two known genes, despite the existence of substantial genetic heterogeneity, thus demonstrating the great promise of these methods for the dissection of late-onset oligogenic diseases.  (+info)

Analysis of affected sib pairs, with covariates--with and without constraints. (7/5966)

Covariate models have previously been developed as an extension to affected-sib-pair methods in which the covariate effects are jointly estimated with the degree of excess allele sharing. These models can estimate the differences in sib-pair allele sharing that are associated with measurable environment or genes. When there are no covariates, the pattern of identical-by-descent allele sharing in affected sib pairs is expected to fall within a small triangular region of the potential parameter space, under most genetic models. By restriction of the estimated allele sharing to this triangle, improved power is obtained in tests for genetic linkage. When the affected-sib-pair model is generalized to allow for covariates that affect allele sharing, however, new constraints and new methods for the application of constraints are required. Three generalized constraint methods are proposed and evaluated by use of simulated data. The results compare the power of the different methods, with and without covariates, for a single-gene model with age-dependent onset and for quantitative and qualitative gene-environment and gene-gene interaction models. Covariates can improve the power to detect linkage and can be particularly valuable when there are qualitative gene-environment interactions. In most situations, the best strategy is to assume that there is no dominance variance and to obtain constrained estimates for covariate models under this assumption.  (+info)

Identification of a C/G polymorphism in the promoter region of the BRCA1 gene and its use as a marker for rapid detection of promoter deletions. (8/5966)

Reduced expression of BRCA1 has been implicated in sporadic breast cancer, although the mechanisms underlying this phenomenon remain unclear. To determine whether regulatory mutations could account for the reduced expression, we screened the promoter region by sequencing in 20 patients with sporadic disease. No mutations were detected; however, a new polymorphism consisting of a C-to-G base change within the beta-promoter was identified, with the frequency of the G allele being 0.34. Close to complete linkage disequilibrium was found between this marker and the Pro871 Leu polymorphism, situated in exon 11, which has previously been shown not to be associated with breast or ovarian cancer. This indicates that the C/G polymorphism is also unlikely to play a role in either disease. However, the strength of linkage disequilibrium between these markers permitted their use for rapid screening for genomic deletions within BRCA1. A series of 214 cases with familial breast cancer were analysed using this approach; 88/214 were heterozygous for the promoter polymorphism, thereby excluding a deletion in this region. Among the remaining patients, one hemizygous case reflecting a promoter deletion was successfully identified. Therefore, this study indicates that deletions within the beta-promoter region of BRCA1 are an uncommon event in familial breast cancer. Furthermore, it suggests that mutations within the BRCA1 promoter are unlikely to account for the reported decreased expression of BRCA1 in sporadic disease.  (+info)

TY - JOUR. T1 - Multivariate logistic regression for familial aggregation in age at disease onset. AU - Matthews, Abigail G.. AU - Finkelstein, Dianne M.. AU - Betensky, Rebecca. PY - 2007/6/1. Y1 - 2007/6/1. N2 - Familial aggregation studies seek to identify diseases that cluster in families. These studies are often carried out as a first step in the search for hereditary factors affecting the risk of disease. It is necessary to account for age at disease onset to avoid potential misclassification of family members who are disease-free at the time of study participation or who die before developing disease. This is especially true for late-onset diseases, such as prostate cancer or Alzheimers disease. We propose a discrete time model that accounts for the age at disease onset and allows the familial association to vary with age and to be modified by covariates, such as pedigree relationship. The parameters of the model have interpretations as conditional log-odds and log-odds ratios, which can ...
Multiple sclerosis (MS) involves immune attacks on the CNS, leading to demyelination, axonal injury and increasing neurological dysfunction. Though T cells are implicated, the particular subsets and their antigenic targets remain unknown. In adult-onset MS, distinguishing immune responses that are consequences of, rather than cause of, injury, is difficult. In contrast, pediatric-onset MS offers an early window into disease mechanisms given the narrower gap from biological onset. We aim to identify and characterize disease-relevant antigen-specific effector T cell responses to traditional and novel antigenic targets involved early in the MS disease process.. Our group has implicated target antigens and T cell subsets in pediatric-onset MS, by following patients from time of an initial presentation with acquired demyelinating syndrome and comparing those confirmed to have MS with those who remain monophasic. A CSF proteomic study implicated novel axo-glial apparatus molecules as early injury ...

We tested for the first time whether significant brain alterations already occurred in POMS patients in their early adulthood and with ...
Cancer is in essence a genetic disease, brought about by an accumulation of alterations in genes that encode proteins responsible for the control of cell growth, cell death and the maintenance of genomic integrity. Recent years have seen the unravelling of numerous genes that are targeted in carcinogenesis. Although several genes implicated in breast cancer have been identified, a substantial proportion of breast cancer cases is not linked to any definite gene, implying that more gene targets remain to be discovered. Based on clinicopathological differences observed between early and late onset breast cancers, it has been proposed that they may be biologically different with separate genetic origins and/or development. The work included in this thesis was initiated with the intent to identify some of the genetic aberrations that characterise early onset breast cancer.. The p53 protein is central in cell cycle control and alterations in its gene sequence are among the most commonly observed ...
Abstract Background Cyclic Vomiting Syndrome (CVS) is a well-recognized functional gastrointestinal disorder in children but its presentation is poorly understood in adults. Genetic differences in pediatric-onset (presentation before age 18) and adult-onset CVS have been reported recently but their clinical features and possible differences in response to therapy have not been well studied. Methods This was a retrospective review of 101 CVS patients seen at the Medical College of Wisconsin between 2006 and 2008. Rome III criteria were utilized to make the diagnosis of CVS. Results Our study population comprised of 29(29%) pediatric-onset and 72 (71%) adult-onset CVS patients. Pediatric-onset CVS patients were more likely to be female (86% vs. 57%, p = 0.005) and had a higher prevalence of CVS plus (CVS + neurocognitive disorders) as compared to adult-onset CVS patients (14% vs. 3%, p = 0.05). There was a longer delay in diagnosis (10 ± 7 years) in the pediatric-onset group when compared to (5 ± 7
The salient findings of our study are that both adult- and pediatric-onset CVS patients have a similar demographic profile and disease characteristics except that pediatric-onset patients were more likely to be female and had a higher prevalence of CVS-plus with concomitant neurological disorders. This finding may be explained by the genetic differences that have been elucidated in previous studies [2, 10, 11]. The pediatric-onset group also had a lower incidence of tobacco and opiate use and a significantly longer delay in diagnosis of CVS. This longer delay in diagnosis is an unexpected finding given that CVS is fairly well-recognized condition in children. It should be noted that though our center attracts both children and adults with CVS, the majority of the patients with pediatric-onset CVS were not transitioned from the Childrens Hospital of Wisconsin, which is also a tertiary center for pediatric CVS. Dysautonomia was diagnosed in 64 % of our CVS patients which we recently reported to ...

Pulmonary arterial hypertension is a rare disease with high mortality despite recent therapeutic advances. The disease is caused by both genetic and environmental factors, and likely gene x environment interactions. While PAH can manifest across the lifespan, pediatric-onset disease is particularly challenging because it is frequently associated with a more severe clinical course and comorbidities including lung/heart developmental anomalies. In light of these differences, it is perhaps not surprising that emerging data from genetic studies of pediatric-onset PAH indicate that the genetic basis is different than that of adults. There is a greater genetic burden in children, with rare genetic factors contributing to at least 36% of pediatric-onset idiopathic PAH (IPAH) compared to ~11% of adult-onset IPAH. De novo variants are frequently associated with PAH in children, and contribute to at least 15% of all pediatric cases. The standard of medical care for pediatric PAH patients is based on
Introduction In an attempt to have more accurate information on the epidemiology of psychiatric disorders in different cultures, the WHO launched the World Mental Health (WMH) Surveys Initiative,1 with over 30 participating countries, using an extended and expanded version of the WHO-Composite International Diagnostic Interview (WMH-CIDI),2 based on diagnostic criteria from the International Classification of Diseases and Injuries 10th Revision (ICD-10)3 and the Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSMIV).4 This manuscript is based on the São Paulo Megacity Mental Health Survey (SPMHS),5 carried out in conjunction with the WMH Surveys Initiative,5 which assessed the general population living in the São Paulo Metropolitan Area (SPMA). So far, few population-based surveys assessing psychiatric morbidity in the community have been conducted in Brazil. In the early 90s, the Brazilian Multicentric Study of Psychiatric Morbidity was carried out in three cities, using ...
Our aim was to characterize and validate that the location and age of onset of the tumor are both important criteria to classify colorectal cancer (CRC). We analyzed clinical and molecular characteristics of early-onset CRC (EOCRC) and late-onset CRC (LOCRC), and we compared each tumor location between both ages-of-onset. In right-sided colon tumors, early-onset cases showed extensive Lynch syndrome (LS) features, with a relatively low frequency of chromosomal instability (CIN), but a high CpG island methylation phenotype. Nevertheless, late-onset cases showed predominantly sporadic features and microsatellite instability cases due to BRAF mutations. In left colon cancers, the most reliable clinical features were the tendency to develop polyps as well as multiple primary CRC associated with the late-onset subset. Apart from the higher degree of CIN in left-sided early-onset cancers, differential copy number alterations were also observed. Differences among rectal cancers showed that early-onset ...
Results: The cohort consisted of 27,918 NARCOMS enrollees, 72.7% of whom were female and 90.1% of whom were white. Mean age at symptom onset was 30.1 ± 10.1 years, and age at enrollment was 47.1 ± 11.0 years. The Disability Expectancy Table and P-MSSS afford a detailed overview of disability outcomes in a large MS cohort over a 45-year period. In the first year of disease, 15% of patients reported need of ambulatory aid, and 4% needed bilateral assistance or worse; after 45 years of disease, 76% of patients required ambulatory aid, and 52% bilateral assistance or worse. Proportion of patients who reported minimal or no interference in daily activities (PDDS ≤ 1) declined from 63% in the first year to 8% after 45 years of disease. ...

WEDNESDAY, Feb. 5, 2020 (HealthDay News) -- People who develop Parkinsons disease at a younger age (before age 50) may have malfunctioning brain cells at birth, according to a study that also identified a drug that may help these patients.. At least 500,000 people in the United States are diagnosed with Parkinsons each year. Most are 60 or older at diagnosis, but about 10% are between 21 and 50. Parkinsons is a neurological disease that occurs when brain neurons that make dopamine become impaired or die. Dopamine helps coordinate muscle movement.. Symptoms get worse over time and include slow gait, rigidity, tremors and loss of balance. There is currently no cure.. Young-onset Parkinsons is especially heartbreaking because it strikes people at the prime of life, said study co-author Dr. Michele Tagliati, director of the Movement Disorders Program at Cedars-Sinai Medical Center in Los Angeles.. This exciting new research provides hope that one day we may be able to detect and take early ...

Compared to the childhood-onset sort, less impairment in several cognitive and psychological capabilities are present, plus the adolescent-onset variety could remit by adulthood.[eighteen] In addition to this differentiation, the DSM-5 supplies a specifier for just a callous and unemotional interpersonal design, which demonstrates properties observed in psychopathy and so are thought being a childhood precursor to this disorder. As compared to the adolescent-onset subtype, the childhood onset subtype, especially if callous and unemotional attributes are existing, tend to possess a even worse treatment final result.[19 ...
A 1964 random community survey in Aberdeen of 2511 children aged 10-14 years identified 121 children with asthma and 167 with wheeze with infection. The outcome at age 34-40 years of these children with wheeze, together with that of 167 children selected from those who were asymptomatic, has been described.1 In 1995 we tried to contact the 2056 individuals (now aged 39-45 years) who had had no childhood wheezing; 1799 subjects were traced. We posted questionnaires about symptoms, smoking, and employment to 1758 surviving subjects, of whom 1542 (87.7%) responded (75.0% of 2056).. Attacks of wheezing ever were reported by 239 (15.5%) respondents, of whom 177 (11.5% of 1542) reported adult onset wheeze-that is, onset at or after age 15 years. The prevalence of adult onset wheeze was similar for men and women (10.7% v 13.0%, χ2=1.95, P=0.16). Other subjects reporting wheeze included 17 with onset at age 10-14 years, 27 with onset before age 10 years, and 18 with no age specified.. Of the 177 ...

The accuracy of LFTs have been debated - a complex topic, we recently clarified.3. In the absence of a practical gold standard test for live virus, LFTs have been compared with PCR, which looks for evidence of the virus, alive or dead, in samples from a persons nose or throat. Whereas LFT looks for evidence that a person is shedding larger amounts of live virus and may pass it on.2. In the typical course of infection, symptoms appear a median five-day incubation after exposure to the virus, however, 30-50% of people do not show classic symptoms.8 PCR usually detects virus nucleic acid one to two days after infection, with LFT detecting antigen a day later, both before symptoms may appear. Viral levels peak at symptom onset and wane over the next few days. In the four to eight day transmission window when a person is shedding substantial amounts of virus, with or without symptoms, both PCR and LFT are likely to be positive. Thereafter, their immune system controls the virus and, for the next 17 ...

We found by analysis of cross-sectional data that LADA was four times more common in subjects with FHD. In addition, prospective data showed that subjects who had siblings with diabetes were twice as likely to develop LADA during the 11-year follow-up compared with those without FHD. Together, these findings demonstrate that FHD is a risk factor for LADA of the same magnitude as for type 2 diabetes.. With regard to type 2 diabetes, our study confirms previous findings indicating a four times increased prevalence in subjects with FHD (6-8). For type 1 diabetes, the association with FHD was weak compared with previous data (2). One reason may be that the majority of our type 1 diabetic subjects (66%) had onset at age ≥20. The genetic background may be stronger in subjects with early-onset type 1 diabetes (15). Accordingly, we found that 40% of subjects with onset of type 1 diabetes before the age of 20 had FHD compared with 25% of those with onset during adulthood.. Previous reports have shown ...
As the age of type 2 diabetes onset decreases, the need for primary prevention of CV complications increases - as illustrated in a recent study.

Author summary The promise of effective personalized medicine is dependent upon the ability to identify genetic variants in the population that influence disease risk and then use this information to accurately predict the likelihood of disease incidence for individual patients. High-risk individuals may be entered into clinical trails, pre-clinical intervention strategies, or increased frequency of screening to detect early disease onset. However, the contribution of any one genetic variant to increase disease susceptibility is typically small, with many potential causal variants in the genomic region associated with risk. Therefore, it is important to understand the biological mechanisms by which the variants within a genetic region influence disease susceptibility by refining the set of all variants to those that are highly plausible to be causal. Herein, we describe a method to integrate molecular genomics data with genetic epidemiological data to inform on the underlying molecular mechanisms that

Meta-analyses in adult-onset schizophrenia report loss of normal planum temporale (PT) asymmetry, posited to relate to language and symptoms, but are inconclusive regarding global cerebral torque. PT asymmetry has been reported unchanged in childhood onset schizophrenia. Here the discrepancy is examined in adolescence. Unbiased PT asymmetry and torque measures were obtained on 35 adolescents with schizophrenia or schizoaffective disorder and 31 adolescent controls. Patients had less PT asymmetry than controls, but torque was unchanged. Taken with previous reports, these results in adolescent onset psychosis suggest that local disturbance of cerebral asymmetry increases with patient age; it could indicate that differential rate of change at the cortical surface in the two hemispheres is the mechanism of symptom generation.

AU - McDonald, Christine F. PY - 2014. Y1 - 2014. N2 - Adult-onset asthma and chronic obstructive pulmonary disease (COPD) are major public health burdens. This review presents a comprehensive synopsis of their epidemiology, pathophysiology, and clinical presentations; describes how they can be distinguished; and considers both established and proposed new approaches to their management. Both adult-onset asthma and COPD are complex diseases arising from gene?environment interactions. Early life exposures such as childhood infections, smoke, obesity, and allergy influence adult-onset asthma. While the established environmental risk factors for COPD are adult tobacco and biomass smoke, there is emerging evidence that some childhood exposures such as maternal smoking and infections may cause COPD. Asthma ...

Young-Onset Dementia is dementia that begins before the age of 45. Early Onset Dementia covers dementia which happens between the ages of 45 and 65. Some definitions of Young-Onset Dementia includes anything before 65. A Mayo Clinic study found that Alzheimers Disease was not the primary cause for Young-Onset Dementia. It was more likely to be a neurodegenerative or autoimmune/inflammatory condition. A Johns Hopkins Alert lists several of these conditions, including Creutzfeldt-Jakob disease ...

I was infected with HERPES SIMPLEX VIRUS in 2011, i went to many hospitals for cure but there was no solution, so I was thinking how can I get a solution out so that my body can be okay. One day I was in the river side thinking where I can go to get solution. so a lady walked to me telling me why am I so sad and i open up all to her telling her my problem, she told me that she can help me out, she introduce me to a doctor who uses herbal medication to cure HERPES SIMPLEX VIRUS and gave me his email, so i mail him. He told me all the things I need to do and also give me instructions to take, which I followed properly. Before I knew what is happening after two weeks the HERPES SIMPLEX VIRUS that was in my body got vanished . so if you are also heart broken and also need a help, you can also email him at {[email protected] ...
What is early onset Parkinsons disease, and how is it different? Learn how Parkinsons can affect younger individuals how their experience may differ.
Background: There is wide variation in the phenotypic expression of Parkinsons disease (PD) which is driven by both genetic and epidemiological influences. for young onset PD. We present here baseline clinical data from this large and demographically representative cohort. Results: 2247 PD cases were recruited (1987 recent onset 260 young onset). Recent onset cases had a mean (standard deviation SD) age of 67.6 years (9.3) at study entry 65.7% PKI-402 males with disease duration 1.3 years (0.9) MDS-UPDRS 3 scores 22.9 (12.3) LEDD 295?mg/day (211) and PDQ-8 score 5.9 (4.8). Young onset cases were 53.5 years old (7.8) at study entry 66.9% male with disease duration 10.2 years (6.7) MDS-UPDRS 3 scores 27.4 (15.3) LEDD 926?mg/day (567) and PDQ-8 score 11.6 (6.1). Conclusions: We have established a large clinical PD cohort consisting of young onset and recent onset cases which was created to assess variation in medical expression with regards to hereditary influences and that provides a system for ...

Breast cancer is increasing in the industrialised countries. Due to early detection and adjuvaut treatment with radiotherapy, hormones and chemotherapy, mortality has decreased. The different adjuvant treatments have adverse effects. It is an important task is to estimate the risk of recurrence for the individual patient in order to tailor her individual treatment. This thesis aims at identifying predictors for disease development in primary and disseminated breast cancer.. Histologic grade was strongly correlated to breast cancer mortality in 630 patients with primary breast cancer. The combination of grade, tumour size and lymph node status in the Nottingham Prognostic Index provides a powerful instrument separating patients in groups with excellent, good, intermediate and poor prognosis.. Grade was more sensitive than S-phase fraction in identifying high risk patients and patients with very good prognosis.. Presence of cancer cells in blood- and lymph vessels close to the tumour in patients ...

This mutation was detected in two members of a French family (ROU 118) affected by early onset Alzheimers disease (Campion et al., 1999). The two affected individuals were a parent and child dyad, with onset at ages 24 and 29. Further clinical details were not reported. The APOE genotype of the index case was ε2/ε4. In a subsequent study, another French individual with age at onset of 26 years was reported (Zarea et al. 2016). This patient developed seizures seven years after disease onset.. The mutation was also found in a screen involving whole-exome sequencing of 15 unrelated Chinese patients with familial AD (Jiang et al., 2019). The proband presented with cognitive deficits typical of AD.. ...
A new study led by scientists at the University of Southampton has found that inherited variation in a particular gene may be to blame for the lower survival rate of patients diagnosed with early-onset breast cancer.. Breast cancer is the second leading cause of cancer-related death in women, with nearly 450,000 deaths per year from the disease worldwide. However, women aged 15-39 at diagnosis have a poorer chance of surviving their cancer than older women* (although survival rates for the disease are generally high).. This difference is partly due to the higher incidence of adverse tumour types that occur in younger women, but age is an independent risk factor even after accounting for differences in tumour type and treatment.. The Southampton study - one of the largest ever undertaken into the link between genes and breast cancer survival in women aged 40 or under at diagnosis - looked at which factors, other than the features of the cancer tissue, might contribute to the poorer survival rate ...
Primary open angle glaucoma (POAG) is a genetically and phenotypically complex disease that is a leading cause of blindness worldwide. Previously we completed a genome-wide scan for early-onset POAG that identified a locus on 9q22 (GLC1J). To identify potential causative variants underlying GLC1J, we used targeted DNA capture followed by high throughput sequencing of individuals from four GLC1J pedigrees, followed by Sanger sequencing to screen candidate variants in additional pedigrees. A mutation likely to cause early-onset glaucoma was not identified, however COL15A1 variants were found in the youngest affected members of 7 of 15 pedigrees with variable disease onset. In addition, the most common COL15A1 variant, R163H, influenced the age of onset in adult POAG cases. RNA in situ hybridization of mouse eyes shows that Col15a1 is expressed in the multiple ocular structures including ciliary body, astrocytes of the optic nerve and cells in the ganglion cell layer. Sanger sequencing of COL18A1, a

Results 1217 incident patients were observed, and a capture-recapture incidence of 2.77 per 100 000 person-years (95% CI 2.63 to 2.91). Prevalence on 31 December 2008 was 10.32 per 100 000 individuals (95% CI 9.78 to 10.86). The incident cohort had a higher median age at onset (63.0 vs 58.1 years) and more bulbar onset patients (30.0% vs 19.1%) compared with the prevalent cohort. Incidence and prevalence peaked in the 70-74 year age group followed by a rapid decline in older age. The male:female ratio in the premenopausal age group (1.91, 95% CI 1.32 to 2.79) was not significantly higher than that in the postmenopausal age group (1.50, 95% CI 1.34 to 1.67). ...

This week BioNews reports a study that shows a gene variant (APOEe4) known to increase the risk of Alzheimers disease is involved in the way our brains function (1). Some headlines stated that people could be screened for Alzheimers disease risk, but at the moment it is not easy to diagnose the condition, and even more difficult to predict who will develop it. The causes of Alzheimers disease are not fully understood, and the consequences devastating. Unfortunately, we are all at some degree of risk and, with ever increasing numbers of people affected, there is an urgent need for effective treatments. It has been known for 15 years that the APOEe4 gene variant is a risk factor for late onset Alzheimers disease. The APOE gene exists in several forms (e2, e3 and e4) - and large population studies have shown that the e4 variant increases a persons risk of developing the condition (2). However, the APOEe4 variant is common - a quarter of the UK population have at least one copy - and most ...
Background The major determinant of age-at-onset (AAO) in Huntington disease (HD) is the length of the causative polyglutamine expansion in the huntingtin protein, which is inversely correlated with the AAO and the course of the disease. However, both environmental and genetic factors are thought to modify the disease. Here, genetic factors are proposed to have an essential influence and especially polymorphism in genes associated with HD pathogenesis are thought to act as genetic modifiers. One characteristic feature in HD pathogenesis is mitochondrial dysfunction, which is marked by an impairment of mitochondrial integrity and trafficking leading to a disruption of mitochondrial function and an inhibition of energy supply in the cell. Amongst others, mutant huntingtin was shown to lead to oxidative stress, increased fragmentation of mitochondria and reduced ATP levels. A regulated expression of proteins, involved in mitochondrial fission and fusion (eg, Mfn1, Mfn2) antagonises the pathogenic ...
The findings, which could lead to a new class of cancer drugs, appear in the current issue of ACS Chemical Biology.. These are the first reported small-molecule HuR inhibitors that competitively disrupt HuR-RNA binding and release the RNA, thus blocking HuR function as a tumor-promoting protein, said Liang Xu, associate professor of molecular biosciences and corresponding author of the paper.. The results hold promise for treating a broad array of cancers in people. The researcher said HuR has been detected at high levels in almost every type of cancer tested, including cancers of the colon, prostate, breast, brain, ovaries, pancreas and lung.. HuR inhibitors may be useful for many types of cancer, Xu said. Since HuR is involved in many stem cell pathways, we expect HuR inhibitors will be active in inhibiting cancer stem cells, or the seeds of cancer, which have been a current focus in the cancer drug discovery field.. HuR has been studied for many years, but until now no direct HuR ...

Author(s): Borremans, Benny; Gamble, Amandine; Prager, KC; Helman, Sarah K; McClain, Abby M; Cox, Caitlin; Savage, Van; Lloyd-Smith, James O | Abstract: Understanding and mitigating SARS-CoV-2 transmission hinges on antibody and viral RNA data that inform exposure and shedding, but extensive variation in assays, study group demographics and laboratory protocols across published studies confounds inference of true biological patterns. Our meta-analysis leverages 3214 datapoints from 516 individuals in 21 studies to reveal that seroconversion of both IgG and IgM occurs around 12 days post-symptom onset (range 1-40), with extensive individual variation that is not significantly associated with disease severity. IgG and IgM detection probabilities increase from roughly 10% at symptom onset to 98-100% by day 22, after which IgM wanes while IgG remains reliably detectable. RNA detection probability decreases from roughly 90% to zero by day 30, and is highest in feces and lower respiratory tract samples. Our
A common misconception about Parkinsons is that it only affects older people. Although the average age of onset is 65, Parkinsons can affect adults of any age. It is estimated that 1 in 5 people living with Parkinsons are of working age. This is known as Young Onset Parkinsons.

So during the next 6 months I tried to get my life together again. I was invited to attend a Parkinsons Disease Study Day at the NDDH where one of the speakers was the Chairman of YAPP&Rs (Mrs Emma Bennion) plus 3 consultants and a premier of the video The Uninvited Guest a video about young onset Parkinsons Disease. This study day was aimed at Nurses, Practice Nurses, Community nurses, physio`s, OT`s and Hospital GPs, GPRs and junior Doctors and other Health care staff. The most astonishing aspect to me that day was the lack of knowledge of professionals in dealing with PWP`s and how Parkinsons affects their daily lives. Also to realise how the symptom of PD can change so rapidly from one extreme to another and that PWPs each have their own brand of Parkinsons. As a result of this day I was ask to appear on a Radio Devon phone in program about Parkinsons with Janet Stanley PD nurse specialist and a fellow sufferer Joe Chappell from North Devon.
