urther study is required to demonstrate that early orchidopexy is not inferior to orchidopexy undertaken in boys aged over 1 year. Participation in research can be beneficial for patients and healthcare providers, but may prove demanding at patient, clinician and organizational levels. Patient representatives are supportive of online research to overcome these challenges. The aim of this pilot study was to develop an online recruitment platform and test its feasibility and acceptability while evaluating the accuracy of participant-reported data. The online research platform was developed in a 1-day 'hackathon' with a digital design company. Women who underwent implant-based breast reconstruction in 2011-2016 were invited by letter containing the web address (URL) of the study site and their unique study number. Once online, participants learned about the study, consented, entered data on demographics, treatment received and patient-reported outcome measures (BREAST-Q™), and booked an appointment for a single hospital visit for three-dimensional surface imaging (3D-SI). Real-time process evaluation was performed. The primary endpoint with online access.The results of this pilot demonstrate the online platform to be acceptable, feasible, and accurate for this population from a single institution. The low-burden design may enable participation from centres with less research support and participants from hard-to-reach groups or dispersed geographical locations, but with online access. There are currently few effective drugs to treat the leg symptoms of peripheral arterial disease (PAD). Previous studies have suggested that the nutraceutical, quercetin, can improve exercise performance and reduce pain sensitivity in healthy mice and improve blood supply in a rodent model of acute hind-limb ischaemia. These models may not be relevant to people with PAD. The aim of this study was to examine the effect of quercetin on exercise performance, physical activity and blood supply in a novel mouse model of sustained hind-limb ischaemia. Hind-limb ischaemia was induced in 6-month-old male apolipoprotein E-deficient mice using a novel two-stage surgical procedure. Five days after induction of ischaemia, mice were allocated to commence dietary quercetin or a control diet for 4 weeks. The primary outcome was exercise performance evaluated using a treadmill test. Other outcomes included physical activity, estimated by an open field test, and hind-limb blood supply, assessed by laser Doppler monitoring. A sustained reduction in relative limb blood supply (P < 0.001) was achieved consistently in all 48 mice before allocation to a control (n = 24) or quercetin (n = 24) diet. Quercetin did not improve exercise performance (P = 0.785), physical activity (P = 0.151) or relative limb blood supply (P = 0.954) over the 4-week assessment period. These data suggest that quercetin does not improve exercise performance, physical activity or limb blood supply in mice with sustained hind-limb ischaemia, and therefore is unlikely be an effective treatment for PAD.These data suggest that quercetin does not improve exercise performance, physical activity or limb blood supply in mice with sustained hind-limb ischaemia, and therefore is unlikely be an effective treatment for PAD. Minimally invasive oesophagectomy (MIO) is reported to produce fewer respiratory complications than open oesophagectomy. This study assessed differences in postoperative complications between MIO and hybrid MIO (HMIO) employing thoracoscopy and laparotomy, along with the influence of co-morbidities on postoperative outcomes. Patients with oesophageal cancer undergoing three-stage MIO or three-stage HMIO between 1999 and 2018 were identified from a prospectively developed database, which included patient demographics, co-morbidities, preoperative therapies, and cancer stage. The primary outcome was postoperative complications in the two groups. Secondary outcomes included duration of operation, blood transfusion requirement, duration of hospital stay, and overall survival. There were 828 patients, of whom 722 had HMIO and 106 MIO, without significant baseline differences. Median duration of operation was longer for MIO (325 versus 289 min; P < 0.001), but with less blood loss (median 250 versus 300 mldities rather than operative approach. The surgical treatment of patients with complex ventral hernias is challenging. The aim of this study was to present an international overview of expert opinions on current practice. A survey questionnaire was designed to investigate preoperative risk management, surgical approach and mesh choice in patients undergoing complex hernias repair, and treatment strategies for infected meshes. Geographical location of practice, experience and annual volumes of the surgeons were compared. Of 408 surgeons, 234 (57.4 per cent) were practising in the USA, 116 (28.4 per cent) in Europe, and 58 (14.2 per cent) in other countries. Some 412 of 418 surgeons (98.6 per cent) performed open repair and 322 of 416 (77.4 per cent) performed laparoscopic repair. Most recommended preoperative work-up/lifestyle changes such as smoking cessation (319 of 398, 80.2 per cent) and weight loss (254 of 399, 63.7 per cent), but the consequences of these strategies varied. American surgeons and less experienced surgeons were stricter. tient optimization and issues related to mesh choice and infections require well designed prospective studies. Oncoplastic techniques in breast-conserving surgery (BCS) are used increasingly for larger tumours. This large cohort study aimed to assess oncological outcomes after oncoplastic BCS (OPS) versus standard BCS. Data for all women who had BCS in three centres in Stockholm during 2010-2016 were extracted from the Swedish National Breast Cancer Register. All patients with T2-3 tumours, all those receiving neoadjuvant treatment, and an additional random sample of women with T1 tumours were selected. Medical charts were reviewed for local recurrences and surgical technique according to the Hoffman-Wallwiener classification. Date and cause of death were retrieved from the Swedish Cause of Death Register. The final cohort of 4178 breast cancers in 4135 patients was categorized into three groups according to surgical technique 3720 for standard BCS, 243 simple OPS, and 215 complex OPS. selleckchem Median duration of follow up was 64 (range 24-110)months. Node-positive and large tumours were more common in OPS than in standard BCS (P < 0.
