A dysbiotic intestinal microbiome has been linked to chronic diseases such as obesity, which may suggest that interventions that target the microbiome may be useful in treating obesity and its complications. Appetite dysregulation and chronic systemic low-grade inflammation, such as that observed in obesity, are possibly linked with the intestinal microbiome and are potential therapeutic targets for the treatment of obesity via the microbiome. Dietary pulses (e.

Background: Several new adjustable-loop devices (ALDs) for anterior cruciate ligament reconstruction (ACLR) have not been tested in vitro.

Purpose: To compare the biomechanical performances of 5 ALDs under a high cyclic load and forces representative of the return-to-play conditions seen in the recovering athlete.

Study Design: Controlled laboratory study.

Article Synopsis
  • * An 81-year-old man with an arteriovenous fistula (AVF) presented with an aggressive form of well-differentiated metastatic SCC, leading to the necessity of an axillary lymph node dissection after excising the primary cancer.
  • * The combination of factors such as immunosuppression, chronic inflammation, and trauma to the AVF contributed to the aggressive nature of SCC in this patient, highlighting the need for careful monitoring and management of skin cancers in individuals

Objective: A significant proportion of the referrals made to a speech investigation clinic in a cleft unit include patients with non-cleft velopharyngeal dysfunction (VPD). This study aims to quantify the underlying diagnoses of these patients and describe the investigative pathway and diagnostic information subsequent to presentation in our clinic.

Materials And Methods: The case notes of 136 consecutive patients with non-cleft VPD who attended our Velopharyngeal Investigation (VPI) clinic from July 2014-December 2019 were reviewed.

Background And Aims: Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and its incidence has increased during the past decade. While hepatitis B and C virus infections and alcohol were established risk factors, the impact of smoking on the incidence and mortality of HCC was needed to be confirmed.

Methods: We reviewed cohort and case-control studies evaluating the association between cigarette smoking and incidence and mortality of HCC from MEDLINE and Google Scholar.

Oral mucosal wounds are characterized by rapid healing with minimal scarring, partly attributable to the "enhanced" wound healing properties of oral mucosal fibroblasts (OMFs). Hepatocyte growth factor (HGF) is a pleiotropic growth factor, with potential key roles in accelerating healing and preventing fibrosis. HGF can exist as full-length or truncated (HGF-NK), NK1 and NK2 isoforms.

Background: Infrared thermography (IRT) has become an increasingly utilized adjunct to more expensive and/or invasive investigations in a range of surgical fields, no more so than in plastic surgery. The combination of functional assessment, flow characteristics and anatomical localization has led to increasing applications of this technology. This article aims to perform a systematic review of the clinical applications of IRT in plastic surgery.

Both laser therapy and cryotherapy have been used with good results in the ablation of cutaneous melanoma metastases. There is less literature evidence in support of cryotherapy. Carbon dioxide laser therapy is a simple, low cost, patient-friendly technique, effective for palliation of individual lesions.

Aim: This paper aims to simplify the approach to reconstruction of the perineum after resection of malignancies of the anal canal, lower rectum, vulva, and vagina.

Materials And Methods: The data were collected from 2 centers, namely, Addenbrooke's Hospital, University of Cambridge, United Kingdom and Christchurch Hospital, University of Otago, New Zealand. All patients who underwent perineal reconstruction from 1997 to 2009 at Christchurch Hospital (13 years) and 2001 to 2009 at Addenbrooke's Hospital (9 years) were included.

Ultrasonic imaging using complementary coded pulses offers the SNR improvements of signal coding without the filter side-lobes introduced by single-transmit codes. Tissue motion between coded pulse emissions, however, can introduce high side-lobes caused by misalignment of complementary filter outputs. This paper presents a method for filtering and motion compensation of complementary coded signals appropriate for use in medical imaging.

Aesthetic surgery is, in the USA at least, no longer a taboo subject. Outside North America, public acceptance continues to grow as more procedures are performed each year. While there appears, anecdotally, to be a decrease in patients undergoing cosmetic treatments because of the global financial crisis, the overall trend remains upward.
