Non-adherence is defined as: "the extent to which a person's behaviour - taking medication, following a diet, and/or executing lifestyle changes, corresponds with agreed recommendations from a health care provider". Non-adherence in chronic cardiometabolic diseases including diabetes is very common and is often the primary reason for treatment failure. This leads to significant excess costs to the health economy through avoidable investigations, treatment escalations, hospital admissions, and disease complications. Methods to diagnose non-adherence have until recently been poor. We have recently developed an objective and robust chemical adherence test to detect the presence of 160 cardiovascular medications in urine using high performance liquid chromatography-tandem mass spectrometry (LC-MS/MS). Chemical adherence testing has not been utilised in people with diabetes, further its relationship with other measures of adherence is unknown. The main aim of this observational study is to compare chemical non-adherence with other commonly used measures of non-adherence in people with diabetes. Chemical testing for non-adherence will be performed using urine provided by 600 patients with poorly controlled diabetes attending primary care recruited over a 15-month period. Participants will also be required to complete a self- reported questionnaire and pharmacy records will be reviewed to ascertain prescription refill rates. The prevalence and metabolic control of non-adherence as diagnosed chemically will be compared with those obtained by pharmacy refill rates and patient self-reported questionnaires. Further, the determinants of non-adherence as ascertained by urine LC-MS/MS analysis will be studied. It is hoped that this innovative study will lead to further larger intervention studies that will change the management of non-adherence in diabetes.
A retrospective study to investigate the method called The Halland Obesity Municipal Effort for children. All children participating in the intervention since the start of this specific method will be eligible for inclusion. The aims are to describe participants and the method-specific activities they are participating in, as well as the effect on their health and school grades.
High blood pressure is a leading risk factor for cardiovascular disease. Traditionally, one of the ways to treat or prevent high blood pressure is to prescribe aerobic exercise training (i.e. brisk walking). Stretching may also be effective because it may cause changes in blood vessel stiffness and therefore reduce resistance to blood flow. The study will assess a group of individuals (i.e. 96) participating in a supervised stretching or walking program five days per week for six months to determine whether stretching is superior for reducing blood pressure. This research will contribute to recommendations about the most effective exercise programs for reducing blood pressure and risk of cardiovascular disease.
Portal hypertension contributed to the main complications of liver cirrhosis. Currently, hepatic venous pressure gradient (HVPG) was the reference standard for evaluating portal pressure in patients with cirrhosis. However, the practice of HVPG is limited to require the extensive experience and highly specialized centers. In recent years, non-invasive methods were proposed to predict the degree of cirrhotic portal hypertension. Of them, liver stiffness measured by transient elastography had shown good performance for predicting clinically significant portal hypertension. However, liver stiffness only has a good correlation with portal pressure in the early stage of portal hypertension (HVPG<10 mmHg), because liver fibrosis is the main cause of portal hypertension in this period. In the stage of clinically significant portal hypertension (CSPH) (HVPG≥10 mmHg), increased portal vein inflow due to splanchnic vasodilation and hyperdynamic circulation, spleen stiffness may have a better correlation with HVPG than that of liver stiffness. Several studies have explored the combination of liver stiffness, platelet count and spleen stiffness for varices screening. However, there are few studies to report the above parameters for assessing CSPH and unneeded HVPG avoiding. Since the spleen was stiffer than the liver, the current vibration-controlled transient elastography examination is dedicated to the liver, rather than the spleen. Very recently, a novel spleen-dedicated stiffness measured by transient elastography was proposed. The prospective, multicenter study aims to add spleen stiffness as a supplementary parameter to establish new criteria for identify CSPH in patients with compensated cirrhosis, with a dedicated probe on transient elastography equipment to assess spleen stiffness and liver stiffness, and further develop a novel model based on spleen stiffness for predicting the liver decompensation in patients with compensated cirrhosis.
Objectives and aim: To evaluate the long-term spill-over (indirect) effect of Coronavirus disease (COVID-19) on health outcomes and healthcare utilization among people with non-communicable diseases and without COVID-19. Design: A population-based cohort study using electronic health records of the Hospital Authority (HA) clinical management system, economic modeling, and serial cross-sectional surveys on healthcare service utilization. Setting: HA public hospitals and outpatient clinics in Hong Kong Participants: People aged ≥ 18 years with a documented diagnosis of diabetes mellitus, hypertension, cardiovascular disease, cancer, chronic respiratory disease, and chronic kidney disease; without COVID-19; attending HA services between 2010 and 2024. Main outcome measures: All-cause mortality, disease-specific outcomes, healthcare service utilization, and costs. Methods: The annual incidence of each outcome in each year between 2010 and 2024 will be calculated. An interrupted time-series analysis to assess the changes in outcomes between pre-and-post-COVID-19 outbreak periods. Long term health economic impact of healthcare disruptions during the COVID-19 outbreak will be modeled using microsimulation. Multivariable Cox proportional hazards regression and Poisson/negative binomial regression to evaluate the effect of different modes of care on the risk of the outcomes. Implications: Findings will inform policies and practices on contingency care plans to avoid excessive morbidity and mortality and to assure the quality of care for patients with NCD as part of the territorial response to the health crisis.

This study aims to compare the efficacy of PSLT and the topical use of prostaglandin-like hypotensive eye drops in the treatment of ocular hypertensive or glaucomatous patients in decreasing intraocular pressure and measuring changes in functional, structural and biomechanical parameters evaluated by computerized perimetry and optical coherence tomography (OCT) related to pressure change resulting from treatments
BACKGROUND: Preeclampsia (PE) is a serious syndrome that affects 3-7% of all pregnant women. PE is characterized by hypertension and kidney problems after the 20th week of pregnancy and is associated with an increased risk of serious cardiovascular complications including death in both mother and fetus. The underlying disease mechanisms are not clear, but that there are changes in the vessels and their function is generally accepted. Today, there is a lack of medical treatment in the form of medicines. HYPOTHESIS: So-called oxidative stress and deficiency of the vasodilator nitric oxide (NO) play an important role in disease onset and complications in PE. WORK PLAN: This interdisciplinary project combines clinical and experimental studies to investigate the significance of oxidative stress and NO deficiency in PE. We have shown in previous studies that nitrate, which is found in high levels in lettuce and beets, can be converted to NO in the body. In a feasibility study, blood samples were taken from women with PE and healthy pregnant women. Analysis of these samples has shown that women with PE and their newborns have lower levels of nitrate and markers of NO in the blood. In a clinical study, the physiological effects (cardiovascular function, renal function, metabolic function) of an increased daily nitrate intake (in the form of a specially developed beetroot juice) are examined in patients with PE. Blood and urine samples are collected before and after beetroot intervention and during childbirth when umbilical cord and placenta samples are also collected. The samples are analyzed with biochemical analyzes with regard to e.g. oxidative stress and NO. IMPORTANCE: The project is expected to contribute new and important knowledge regarding the disease mechanisms, which may enable new treatment strategies in PE.
The purpose of this research study is to find out the usefulness of checking a woman's blood pressure remotely (at home) for 3 weeks after being discharged from the hospital after having a baby (or babies). Some women can develop hypertension, or high BP, after delivery even if they have not had this problem before or during their pregnancy. Untreated or unknown high BP can lead to medical complications, and if severe, can be life threatening. Monitoring, or checking, remote BP after a woman has delivered her baby (or babies) has been suggested to be a better way to monitor BPs without having to stay in the hospital for a longer time after delivery. Other researchers report that women who have checked their BP remotely after delivery found out that this was both possible and acceptable.
