Aim: Recovery after surgery for colorectal cancer is a complex process, involving numerous physiological, emotional, social and economic challenges. Good information is a key factor for enabling patients to recover well, but there is a paucity of evidence to guide how this should be done. A new information intervention (Recover Together) comprising a booklet, an online video and an inpatient goal board has been developed.

Article Synopsis
  • Hand eczema is a common skin problem that can be painful and make it hard for people to work, and there isn’t a clear treatment plan agreed on by doctors in the UK.
  • This study aimed to compare two treatments, alitretinoin and ultraviolet therapy, to see which works better after 12 weeks for patients with severe hand eczema that didn't improve with regular medicine.
  • The results showed that while both treatments helped, alitretinoin was less effective than ultraviolet therapy in reducing the severity of the eczema after 12 weeks.

Background: Posterior cervical foraminotomy and anterior cervical discectomy are routinely used operations to treat cervical brachialgia, although definitive evidence supporting superiority of either is lacking.

Objective: The primary objective was to investigate whether or not posterior cervical foraminotomy is superior to anterior cervical discectomy in improving clinical outcome.

Design: This was a Phase III, unblinded, prospective, United Kingdom multicentre, parallel-group, individually randomised controlled superiority trial comparing posterior cervical foraminotomy with anterior cervical discectomy.

The UK NHS Women's National Breast Screening programme aims to detect breast cancer early. The reference standard approach requires mammograms to be independently double-read by qualified radiology staff. If two readers disagree, arbitration by an independent reader is undertaken.

Objective: To analyze the impact of modern glucose-monitoring strategies on glycemic and patient-related outcomes in individuals with type 2 diabetes (T2D) and recent myocardial infarction (MI) and assess cost effectiveness.

Research Design And Methods: LIBERATES was a multicenter two-arm randomized trial comparing self-monitoring of blood glucose (SMBG) with intermittently scanned continuous glucose monitoring (isCGM), also known as flash CGM, in individuals with T2D and recent MI, treated with insulin and/or a sulphonylurea before hospital admission. The primary outcome measure was time in range (TIR) (glucose 3.

Article Synopsis
  • Hand eczema (HE) is a widespread skin condition affecting up to 10% of the population, causing significant morbidity and work-related issues, with limited treatment guidelines from current research.
  • In a study involving 194 UK dermatologists, various treatments were surveyed, with alitretinoin (AL) and psoralen combined with UVA (PUVA) being popular but many clinicians unsure about the best long-term outcomes.
  • The ALPHA trial is a randomized controlled study comparing PUVA and AL, aiming to gather data on treatment effectiveness and patient responses over 52 weeks, with ongoing assessments and a focus on genetic factors influencing HE severity.

Background: Preliminary studies using the FENIX™ (Torax Medical, Minneapolis, MN, USA) magnetic sphincter augmentation device suggest that it is safe to use for the treatment of adult faecal incontinence, but efficacy data are limited.

Objective: To compare FENIX with sacral nerve stimulation for the treatment of adult faecal incontinence in terms of safety, efficacy, quality of life and cost-effectiveness.

Design, Setting And Participants: Multicentre, parallel-group, unblinded, randomised trial comparing FENIX with sacral nerve stimulation in participants suffering moderate to severe faecal incontinence.

Objectives: Colorectal cancer (CRC) is a leading cause of cancer death worldwide, although effective uptake of bowel cancer screening is below 60% in England. This trial investigated the influence of volitional and motivational interventions and their combination on increasing guaiac fecal occult blood testing (gFOBT) screening uptake.

Method: In total, 34,633 participants were recruited (via North-East of England bowel cancer screening hub) into a 2×2 factorial cluster randomized controlled trial.

Background: Sexual history does not accurately identify those with extragenital Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT), so universal extragenital sampling is recommended. Nucleic acid amplification tests (NAATs) are expensive. If urogenital, plus rectal and pharyngeal, samples are analyzed, the diagnostic cost is trebled.

Background: Urogenital testing misses extragenital Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT). Extragenital self-sampling is frequently undertaken despite no robust randomized, controlled trial evidence of efficacy. We compared clinician-taken rectal and pharyngeal samples with self-taken samples for diagnostic accuracy and cost in men who have sex with men (MSM) and in females.

Background: Rapid molecular point-of-care tests (POCTs) for influenza have potential to produce cost savings in emergency departments (EDs) and acute care settings. To date, published projected savings have been based on estimated costs.

Objectives: This study aimed to describe the cost implications of a rapid influenza POCT using accurate real-world patient level costing data.

Purpose: Relapse after complicated intra-abdominal infection (cIAI) remains common after treatment. The optimal antibiotic treatment duration for cIAIs is uncertain, especially in cases where source control is not achieved. We hypothesised that in patients with cIAIs, regardless of source control intervention, there would be a lower relapse rate with long-course antibiotics (28 days) compared with short course (≤ 10 days).

Background: In primary care, multiple priorities and system pressures make closing the gap between evidence and practice challenging. Most implementation studies focus on single conditions, limiting generalisability. We compared an adaptable implementation package against an implementation control and assessed effects on adherence to four different evidence-based quality indicators.

Background: Pressure ulcers (PUs) are a burden to patients, carers and health-care providers. Specialist mattresses minimise the intensity and duration of pressure on vulnerable skin sites in at-risk patients.

Primary Objective: Time to developing a new PU of category ≥ 2 in patients using an alternating pressure mattress (APM) compared with a high-specification foam mattress (HSFM).

Background: Precision medicine is heralded as offering more effective treatments to smaller targeted patient populations. In breast cancer, adjuvant chemotherapy is standard for patients considered as high-risk after surgery. Molecular tests may identify patients who can safely avoid chemotherapy.

Article Synopsis
  • This systematic review examines various laparoscopic retraction devices to determine their effectiveness and impacts on surgical outcomes, including operation time and patient recovery.
  • After analyzing 12 selected studies, researchers found that no tested devices increased patient morbidity or conversion rates to open surgery, and many could reduce the need for additional staff during procedures.
  • Ultimately, while all devices improved the surgical field of vision, reusable instruments are suggested as more economically and environmentally favorable options, though clinical suitability is the main deciding factor.

Article Synopsis
  • - The study aimed to assess dental care spending among Mexican households across the years 2000, 2002, and 2004 by analyzing national survey data and identifying factors influencing expenditure decisions.
  • - In terms of costs, over 6,467 million pesos were spent in 2000, with notable declines in 2002, but an increase again in 2004; meanwhile, the incidence of catastrophic dental expenses varied across the years.
  • - The analysis indicated that factors like municipal development, household stratum, and the age of the household head significantly impacted dental spending, highlighting disparities in health care financing among the Mexican population.

Objective: To estimate the effectiveness of using standardized health vignettes to adjust self-reported health taking into account household and community variables to correct for systematic bias.

Material And Methods: The national health survey "Evaluación del Desempeño 2002" (Mexican component of the World Health Survey) was used. This survey analyzed subject's health perception based on their responses to hypothetical questions referring to third parties in the vignettes within eight domains.
