Filter by:Self-care and self-medication are commonly the treatments of choice for the management of minor ailments. Minor ailments can be treated through community pharmacy using a Minor Ailment Service (MAS). The INDICA+PRO Impact Study, evaluated the clinical, economic and humanistic impact of a MAS, concluding that community pharmacies could greatly benefit the health system. Thus, the following objectives were defined for the INDICA+PRO implementation study. The primary objective is to implement a standardised MAS in usual practice in community pharmacy in Spain. The secondary objectives include an evaluation of the clinical and economic outcomes and the role and impact of two different models of change agents. A pragmatic study with an effectiveness-implementation hybrid design type 3 will be undertaken using the Framework for the Implementation of Services in Pharmacy (FISpH). The study will be carried between October 2020 and December 2022. Two type of practice change facilitators FaFa and SEFaFa. Their main function, using the Observe-Plan-Do-Study-Act process, will be to facilitate the implementation through individualised continuous support to providers of the MAS. The depth and breadth of support to pharmacist providers by each type of change agents will vary. Pharmaceutical Associations (PA) and/or Spanish Society of Community Pharmacy (SEFAC) will invite community pharmacies/pharmacists. Participating pharmacists will need to sign a commitment form. The second study population will consist of patients presenting with minor ailments or requesting a non-prescription medication. Recruitment of patients will be carried out by the pharmacist providers. The inclusion criteria will be: patients or caregivers (aged ≥18 years, or younger if they are accompanied by an adult) presenting with 31 minor ailments, grouped into five categories (respiratory, moderate pain, digestive, dermatological and other) with pre-agreed referral protocols. Other symptoms may be included at the discretion of the pharmacists. The exclusion criteria will be patients who do not provide informed consent. The patient/pharmacist intervention will consist of a MAS protocol adapted for each symptom. The consultation will be record in an electronic data capture system (SEFAC eXPERT®-) that provides a step-by-step approach with protocols and clinical information embedded. The FISpH model will be used to guide the implementation of MAS. Two types of change agents, FaFas and SeFaFas, previously trained for 18 hours, will be used to facilitate the implementation. During each of the stages (exploration, preparation, testing and operation, and initial sustainability), strategies will be used by FaFas and SeFaFas to moderate implementation factors. The impact of strategies will be evaluated. Data on pharmacy/pharmacist's provider performance and patient outcomes will be provided to pharmacist, change agents and PA and SEFAC. FaFas and SeFaFas will have a classification system for barriers and facilitators derived from the constructs in the Consolidated Framework for Implementation Research (CFIR). The classification system for implementation strategies consists of an adaptation of the facilitation activities listed by Dogherty et al. These will be documented in an electronic data capture system. FaFas will train their pharmacists (max. of 25 pharmacies) for 6 hours and subsequently provide at least monthly follow-up. The research team will provide ongoing feedback and support to the FaFas and SeFaFas through periodically, hold group meetings by video conference between the research group and all the FaFas and SeFaFas. The research group will provide formal reports on the implementation process and patient outcomes. Other forms of communication such as emails, telephone calls or WhatsApp messaging will also be available. Implementation and patient consultation process and outcome variables will be measured such as reach, fidelity and integration. Outcome service indicators will be clinical, economic and humanistic. A patient follow up will occur at a maximum of 10 days. Continuous variables will be reported using mean and standard deviation, or median and percentiles. Categorical variables will be reported using percentages. T Student's test or the ANOVA test or Kruskal-Wallis. χ2 test, Fisher's exact test or Yate's chi-squared will also be used. To determine the relationship between the dependent and the independent variables, logistic regression models will be performed including the variables with statistical significance in the bivariate model. The level of significance will be set at p <0.05. Machine learning and big data techniques are being considered for predictive modelling. The research team will only have access to de-identified data of pharmacists and patients. This study protocol has been approved by the Granada Research Ethics Committee on the 5th February 2020.
Varicose veins (VV) are the early sign of Chronic venous insufficiency (CVI) which are characterised by abnormal tortuosity and dilatation of superficial veins of lower limb extremities. Factors for the development of VV exist in literature. However, the exact mechanism remains unclear. The prevalence of VV are greater in women compared to men and also higher in pregnant women compared to non-pregnant women which make pregnant women at higher risk of developing VV. Furthermore, complications of VV have negative impacts on patients' quality of life and health care budget. Therefore, better understanding of the cause of VV can contribute in better quality of life to the patient and provide valuable insights to help in reducing health care cost. The present study will investigate the contribution of both mechanical and chemical factors in pregnant women by taking blood samples for genomic testing, using Duplex ultrasound, vector flow imaging, limb volume assessment using Truncated cone tool, assessment of iliac vein compression using Photoplethysmography (PPG) technique, hormonal blood test and assessing patient's quality of life using Aberdeen Varicose Veins Questionnaire (AVVQ).
This study is designed to find if the venoactive drug contained diosmin and hesperidin is able to work against chronic vein-specific inflammation by changing the level of Monocyte Chemoattractant Protein 1. This chemokine is involved in the vein wall remodeling in patients with lower limb varicose veins.
The operating room environment can be a source of anxiety for the patient, including in the context of outpatient surgery for which anxiolytic medication is rarely used. This anxiety-induced effect can be reinforced by the patient's lack of active participation. Some studies have already shown the feasibility of patient walking to the operating room (OR) and advantages this approach(Kojima and Ina 2002; Lack 2016; Nagraj et al. 2006). Moreover, recovery room complications and pain have also been shown to be greater after varicose vein surgery in patients with significant preoperative anxiety (Scavee et al. 2016). Therefore, the investigators decided to test the effects of walking to OR for patients admitted for outpatient surgery for varicose vein surgery.
This study is a retrospective, multi-center and observational clinical study. Renmin Hospital of Wuhan University, Beijing Friendship Hospital, Capital Medical University, The fifth medical center of PLA General Hospital, Zhongshan Hospital, Fudan University, Shanghai, Nanjing Drum Tower Hospital affiliated Nanjing University Medical School and Xiangyang Central Hospital will participate in the study. Investigators would like to provide evidence-based medical evidence by evaluating and comparing the efficacy and safety of endoscopic ultrasound (EUS)-guided coil embolization combined with endoscopic cyanoacrylate injection and balloon-occluded retrograde transvenous obliteration (BRTO) in the treatment of gastric varices (GV) with spontaneous portosystemic shunt (SPSS). Between January 2014 and December 2020, patients with GV secondary to portal hypertension admitted to a tertiary medical center, are enrolled consecutively according to the following criteria: (1) age≥18 years; (2)endoscopic examination confirms the presence of GV; (3) CTA of the portal system and EUS revealed the presence of SPSS, the diameter was between 5 mm to 15 mm; (4) treatment with EUS-guided coil combined with endoscopic cyanoacrylate injection or BRTO. Exclusion criteria are as follows: (1)malignant tumors; (2) hepatic encephalopathy, hepatorenal syndrome or multiple organ failure; (3) previously received esophagus or stomach surgery; (4) pregnant. Investigators will collect patients' data of baseline character, treatment, postoperative and follow-up. All patients will be followed up until the progress of the disease or the end of the study. And rebleeding, ectopic embolism, survival, and sequential treatment will be recorded during the follow-up period. The primary endpoint are five-day rebleeding rate and six-week mortality rate. The secondary endpoint are: technical success rate, incidence of ectopic embolism, eradication of GV, one-year rebleeding rate, one-year mortality rate, and cost-effectiveness ratio. All data and information use SPSS statistical software to complete all statistical analysis.
The purpose of this study was to evaluate the safety of early enteral nutrition on endoscopic therapy of esophagogastric varices in Liver Cirrhosis ,and to assess the impact of different eating times on patients, so as to determine the best time for patients to obtain nutrition after surgery.
To establish which of the radiofrequency venous ablation modalities studied in the original 3RF study (Venefit (Closurefast), vs. Radiofrequency induced Thermal Therapy vs. Endovenous Radiofrequency) is most effective in relieving patients' symptoms and signs from varicose veins disease, and in maintaining absence of reflux in the treated vein segment (of the great saphenous vein (GSV)) 5 years following surgery.
The purpose of the RCT trial is to determine whether endovenous radiofrequency closure catheter and endovenous radiofrequency closure generator is not inferior to ClosureFast™ and ClosureRFG™ in treating varicose veins of lower extremity.
Variceal hemorrhage is the serious complication in patients with compensated advanced chronic liver disease (cACLD). To evaluate the bleeding risk of varices in cACLD, esophagogastroduodenoscopy (EGD) should be performed. Once identified with medium-large varices, or small varices with red signs or Child-Pugh C class, defined as varices needing treatment (VNT), the patients with cACLD are recommended to receive the non-selective beta blockers or endoscopic variceal ligation per Baveno VI consensus. However, EGD is limited by its invasiveness and uncomfortableness. The Baveno VI criteria, which was validated by 310 patients dominant with hepatitis C virus (55.0%), recommended that EGD could be spared in patients with liver stiffness (LS) < 20kPa and platelet count > 150×10^9 cells/L. Furthermore, the expanded-Baveno VI criteria (LS < 25kPa and platelet count > 110×10^9 cells/L), based on European cohort with hepatitis C virus (62.8%), was able to spare more unnecessary endoscopies than the Baveno VI criteria with VNT missed rate < 5%. Nevertheless, a recent Asian-pacific study indicated that though Baveno VI criteria was able to avoid screening endoscopy with 27.6%, it increased the odds of missing VNT in hepatitis B virus-related cACLD. Notably, this study also suggested that the expanded-Baveno VI criteria was not suited for Asian-pacific cohort with hepatitis B virus as the dominant cause with VNT missed rate > 5%. Our study aims to develop and validate an optimal cutoff value of LS and platelet count (CHESS criteria) to safely avoid more unnecessary endoscopies in patients with hepatitis B virus-dominated cACLD.
This is a one-arm, open label, prospective, single center study to evaluate clinical standardization with Theraclion's Sonovein 2 HIFU device. The original Sonovein device was tested in a clinical trial in 50 subjects and received CE Mark. That device has been updated yielding the current version of Sonovein 2. Based on the technical similarities between both devices in term of design, performance and principle of operation, the clinical data for Sonovein is sufficient to assure conformity of the Sonovein 2 with the respected essential requirements. At the same time, the compagny wishes to pursue the standardisation of the clinical practice with the second generation device and is, therefore, conducting this limited trial in 20 evaluable cases (from the planned 22 patients to be included). A "case" is defined as procedure conducted on a distinct vein.
