Filter by:This study aimed to determine the effects of Kegel exercise and Ba Duan Jin applications applied to premenopausal women with urinary incontinence on quality of life and psychological well-being. Study Group of the Research: Premenopausal women between the ages of 45-55 who come to the family health center with any complaint and have urinary incontinence. The research will be conducted as a randomized pre-test, post-test and control group intervention study design. The research will be conducted with women aged 45-55 with urinary incontinence who came for examination for any reason to a Family Health Center in Sinop between March 2024 and July 2024. According to the power analysis, the number of participants was calculated to be at least 54 when the type 1 error was taken as 0.05, the power was 0.95 and the effect size was medium (0.25) for the two-group design with two repeated measurements. To prevent possible data loss, the sample size was increased by 10% and the total number of participants was determined as 60. A total of 60 women, 30 experimental and 30 control, coming to the Family Health Center will be randomly included in the study. No information, Kegel exercise program and Ba Duan Jin applications will be given to the women in the experimental group, and no intervention will be given to the control group during the research process. Participants will be assigned to 2 groups: experimental and control. Those who come to FHC on odd days of the month will be included in the experimental group, and those who come on even days of the month will be included in the control group. Each group will be determined as 30 people. After the research is completed, the interventions applied to the experimental group will be applied to the women in the control group. Personal Information Form, Psychological Well-Being Scale and Incontinence Quality of Life Scale will be applied to women in the experimental and control groups as pre-test measurements. As a final test, the same measurements will be made to both the control group and the experimental group 16 weeks after the first measurement.
Newborn screening (NBS) is a global initiative of systematic testing at birth to identify babies with pre-defined severe but treatable conditions. With a simple blood test, rare genetic conditions can be easily detected, and the early start of transformative treatment will help avoid severe disabilities and increase the quality of life. Baby Detect Project is an innovative NBS program using a panel of target sequencing that aims to identify 126 treatable severe early onset genetic diseases at birth caused by 361 genes. The list of diseases has been established in close collaboration with the Paediatricians of the University Hospital in Liege. The investigators use dedicated dried blood spots collected between the first day and 28 days of life of babies, after a consent sign by parents.
This is an international prospective and retrospective registry of patients with Lysosomal Storage Diseases (LSDs) to understand the natural history of the disease and the outcomes of fetal therapies, with the overall goal of improving the prenatal management of patients with LSDs.
Non-alcoholic fatty liver disease (NAFLD) is a multifactorial disease affecting a quarter of the world population. Pathological accumulation of fat, into the hepatocytes, is the first hit and is due to altered hepatic and extrahepatic lipogenesis, lipolysis and lipophagy of the large lipid droplets. Lipophagy plays a key role in the onset of NAFLD, in the autolysosomes, small droplets of fat are catabolized by Lysosomal Acid Lipase (LAL) enzyme which hydrolyzes cholesterol esters and triglycerides forming cholesterol and free fatty acids. Our research group demonstrated that, subjects affected by NAFLD, present a reduced enzymatic activity either compared to patients with chronic liver disease of different etiology, but comparable staging, either compared to healthy control subjects. Leukocytes are the main site of enzymatic activity in the blood, however, our research group has shown that it can also be detected inside the platelets, demonstrating how the LAL activity can be exchanged between cells. Furthermore, our group has shown, for the first time, how the intracellular enzymatic activity is reduced, independently of the platelets and leukocytes count and progressively from chronic liver disease up to cirrhosis. Among factors which contribute to altered lipid metabolism, the genetic predisposition to the accumulation of hepatic fat must be counted. Several variants of genes that code for proteins implicated in the digestion or storage of fats, are involved. In this study were considered: patatin-like phospholipase domain-containing 3 (PNPLA3), Transmembrane 6 superfamily 2 (TM6SF2) and 17β-Hydroxysteroid dehydrogenase type 13 (HSD17B13). The rs738409 variant (C> G, p.I148M) of the PNPLA3 gene consists of a protein in which the catalytic site is not entirely accessible to the substrate which, consequently, accumulates in the storage site. This variant is commonly found in NAFLD subjects and it has been widely reported how the variant carriers progress faster towards severe disease (steatohepatitis) than wild type subjects. The TM6SF2 gene encodes a membrane transporter involved in the triglycerides movement, the rs58542926 (C> T E167K) variant has been associated with an increased predisposition towards liver fibrosis in NAFLD subjects. This is likely due to the loss of protein function resulting in hepatic retention of triglycerides and cholesterol. Unlike PNPLA3 and TM6SF2, the rs72613567 (TA> TAA) variant of the HSD17B13 gene has a protective effect against NAFLD progression. It is characterized by a protein loss of function that protects against chronic liver damage and mitigates the progression of the disease although how the protective effect occurs is still under study. Due to the multifactorial etiology of the disease, to the need of carrying out a targeted surveillance in predisposed genetic subjects and, in order to prevent NALFD progression towards severe pathological forms characterized by an increased mortality, in this study, 316 subjects will be enrolled. They will be divided as follows: Italian Caucasians, aged> 18 and <70 years, with non-cirrhotic NAFLD and carriers of the PNPLA3 I148M variant, and, 158 Italian Caucasian subjects, aged> 18 and <70 years, with non-cirrhotic NAFLD and carriers of the wild type allele. The following exclusion criteria will be considered: any type of malignant disease in the past 5 years, any type of inflammatory or autoimmune disease, corticosteroids for systemic use, any type of drug that may affect body weight or body composition, insufficiency kidney (GFR <90 mL / min), heart failure (NYHA classes II-IV), any type of liver disease rather than NAFLD, excessive alcohol intake (> 140 g / week for men and 70 g / week for women), participation in a weight reduction program in the past 3 months, bile salts, cholestyramine in the last 6 months prior to enrollment, previous cholecystectomy, gallbladder disease. Peripheral blood will be withdrawn in order to measure haematic lipids (total cholesterol and fractions, triglycerides), total blood LAL activity, to perform genetic analysis and finally to evaluate lipase activity into the platelets. Hepatic elastography will be also executed, in 100 patients, according to the presence/absence of the PNPLA3 variant, in order to weigh up the genetic predisposition on NAFLD development or progression Finally, in subjects who present a lipase activity 30% lower than the normal value (0.88 ± 0.38 (mean ± SD), the methylation of the LIPA promoter will be studied.
Investigators will in a crossover study test the health effects of eating a dairy-based protein-rich breakfast, isocaloric carbohydrate-rich breakfast or no breakfast in young overweight women. Determination of satiety and hunger using visual analog scores (VAS), collection of blood samples and 2x 24 hours food logs will be collected.
The investigators aims to determine the the maternal and fetal safety and feasibility of in utero fetal enzyme replacement therapy in fetuses with Lysosomal Storage Diseases.
Familial Hypercholesterolemia (FH) is a monogenic autosomal dominant disease also known as Autosomal Dominant Hypercholesterolemia - ADH) that leads to dramatically increased levels of Low Density Lipoprotein (LDL) and total cholesterol associated to tendon xanthomas, xanthelasma, corneal arcus, premature atherosclerosis and to an increased risk of coronary artery disease (CAD) and myocardial infarction. FH is mainly caused by mutations in genes encoding for proteins affecting hepatic LDL cholesterol uptake including the LDL receptor (LDLR) gene or the gene encoding the only apolipoprotein of LDL, the apolipoprotein B (APOB), or the gene encoding a protease regulating LDLR levels on the cell membrane Lysosomal Acid Lipase A (LIPA) gene encode for Lysosomal acid lipase (LAL) enzyme responsible for hydrolyzing cholesterol esters and triglycerides that are delivered to lysosomes. Mutations in LIPA that completely inactivate LAL are the molecular cause of Wolman disease, a rapidly lethal disease of infancy while mutations in LIPA that result in residual enzymatic activity of LAL are responsible of a disorder characterized by a less severe phenotype known as cholesterol ester storage disease (CESD). Patients with CESD usually show a phenotype characterized by hepatic disease and mixed hyperlipidemia with elevated levels of LDL-C and triglycerides (TG) and decreased HDL-C levels. A broader phenotypic presentation for loss of function mutations in LIPA suggests that LIPA mutations may be considered in patients with apparently monogenic FH in whom mutations in the known candidate genes are not detectable. The project is aimed to evaluate the prevalence and the mutation rate of LIPA gene in subjects with a clinical diagnosis of FH and already genetically characterized in whom pathogenic mutations in the known candidate genes have not been identified. The analysis will be performed in about 250 FH pediatric subjects and putative causal mutations will be also tested for co-segregation in available families in affected and unaffected members.
The very low carbohydrates diet (VLCKD) induces liver steatosis amelioration. Lysosomal acid lipase (LAL) deficiency plays a role in fats accumulation in liver. To date, no studies have assessed LAL activity in morbid obesity. The aim of our study is to evaluate VLCKD impact on metabolic/vascular parameters and LAL activity in obese patients. A VLCKD is administered for 25 days to 52 morbid obese patients (BMI 44.7±8.3 kg/m², age 49±12.5 years); at baseline and after diet we evaluated: BMI, glyco-lipidic pattern, abdominal ultrasonography (liver steatosis and visceral fat area) and flow-mediated dilation (FMD). In a subgroup of 20 patients we also tested lysosomal acid lipase (LAL)-activity. A group of healthy normal weight subjects (age 43±13, BMI 22.8±2.6 kg/m²) was also included in the study.
Lysosomal Acid Lipase (LAL) deficiency is a rare, autosomal recessive storage disease linked to decrease enzymatic activity of LAL, responsible for intracellular accumulation of cholesterol esters and triglycerides. The accumulation of lipid is in hepatocytes, Kupffer cells and macrophages leading to a fatty liver, hepatic fibrosis that can evolve up to cirrhosis. LAL deficiency is responsible for significant morbidity and early mortality in children, adolescents and adults in connection with a multi visceral disease reaching the liver, gastrointestinal tract and the vascular endothelium. The disease is caused by homozygous or heterozygous mutations in the gene (LIPA chromosome 10q23.2-23.3) which is responsible for the synthesis of the LAL. The disease can be diagnosed by enzymatic analysis using few drops of blood absorbed onto blotting paper . Patients with this deficiency LAL, have no or reduced activity of this enzyme. Because of its rarity, the deficit in LAL is under diagnosed or is diagnosed in patients with liver biological disturbances and / or lipid profile disturbances, steatohepatitis-hepatitis (NASH), the steatosis (NAFLD), the cryptogenic cirrhosis or Wilson disease. Inclusion period of 12 to 18 months (100 patients).
