Absorbable staples

Plants compete for light partly by over-producing chlorophyll in leaves. The resulting high light absorption is an effective strategy for out competing neighbors in mixed communities, but it prevents light transmission to lower leaves and limits photosynthesis in dense agricultural canopies. We used a CRISPR/Cas9-mediated approach to engineer rice plants with truncated light-harvesting antenna (TLA) via knockout mutations to individual antenna assembly component genes CpSRP43, CpSRP54a, and its paralog, CpSRP54b...

Metal allergies have been a growing concern in the general population over the past several decades. Laparoscopic cholecystectomy is the standard treatment for gallbladder diseases such as cholelithiasis and cholecystitis, during which surgical clips composed of metals such as nickel or titanium are often used to clamp the arteries and ducts. These metals are documented to produce hypersensitivity reactions. Here, we present the case of a 53-year-old male patient who successfully underwent laparoscopic cholecystectomy and two weeks later reported constant right upper quadrant pain accompanied by nausea that was exacerbated by exercise and food...

INTRODUCTION: Internal herniation (IH) can be a life-threatening complication of Roux-en-Y gastric bypass (RYGB). Randomised controlled trials support the routine closure of mesenteric spaces at RYGB. However, there is currently no consensus on the method of closure in clinical practice. The purpose of this survey is to understand bariatric surgeons' practice in this regard. METHODS: We conducted an international survey, whereby questions were created through collaboration of a consensus group of bariatric surgeons and hosted on the SurveyMonkey platform...

BACKGROUND: Deep surgical site infections after spinal instrumentation represent a significant source of patient morbidity and poorer outcomes. Given lack of evidence or guidelines on the variety of procedural options in the management of deep spine surgical site infections, the purpose of this survey was to document and investigate the use of these techniques across Canada. METHODS: A 34-question survey evaluating surgical techniques for irrigation and debridement in postoperative thoracolumbar infection was distributed to Canadian adult spine surgeons...

Strong-field hexadentate ligands were synthesized and coordinated to cobalt metal centers to result in three new low-spin to low-spin Co(III/II) redox couples. The ligand backbone has been modified with dimethyl amine groups to result in redox potential tuning of the Co(III/II) redox couples from -200 to -430 mV versus Fc+/0 . The redox couples surprisingly undergo a reversible molecular switch rearrangement from five-coordinate Co(II) to six-coordinate Co(III) despite the ligands being hexadentate. The complexes exhibit modestly faster electron self-exchange rate constants of 2...

As long as medicine has subsisted, wound closure has existed. When assessing a surgical wound, physicians are more than ever confronted with various sutures and other closure materials. The surgeon must choose the most appropriate material for that specific closure because not one substance is perfect in all circumstances. The history of suturing wounds is intertwined with the history of surgery. Wound suturing is a critical component of wound therapy, including suturing materials and techniques. Suturing has been practiced for thousands of years...

Biofortification increases micronutrient content in staple crops through conventional breeding, agronomic methods, or genetic engineering. Bioaccessibility is a prerequisite for a nutrient to fulfill a biological function, e.g., to be bioavailable. The objective of this systematic review is to examine the bioavailability (and bioaccessibility as a proxy via in vitro and animal models) of the target micronutrients enriched in conventionally biofortified crops that have undergone post-harvest storage and/or processing, which has not been systematically reviewed previously, to our knowledge...

The Covid pandemic has exposed fissures of inequality through heightened food insecurity and nutritional deficiency for vulnerable social cohorts with limited coping mechanisms. Given the multi-dimensional pathways through which its effects have been felt, several researchers have highlighted the need to analyse the pandemic in specific contexts. Using random and fixed effect regression models, this study analyzed longitudinal survey data collected from 103 Mandinka households in rural and urban Gambia. The study employed convenience and snowball sampling and involved the monthly collection of detailed income, food consumption, expenditure, sourcing, migration, health, and coping mechanism data through mobile phone interviews which yielded 676 observations...

Zinc, through its structural and cofactor roles, affects a broad range of critical physiological functions, including growth, metabolism, immune and neurological functions. Zinc deficiency is widespread among populations around the world, and it may, therefore, underlie much of the global burden of malnutrition. Current zinc fortification strategies include biofortification and fortification with zinc salts with a primary focus on staple foods, such as wheat or rice and their products. However, zinc fortification presents unique challenges...

Background. Anastomotic leak is a feared complication in rectal cancer surgery, and a proximal diverting stoma to protect the rectal anastomosis is used to minimize its impact. We evaluated a novel technique that uses the da Vinci® robotic platform (Intuitive Surgical) to reinforce the colorectal anastomosis and rectal staple line with sutures, and rectal resection and assessment of the anastomotic perfusion, using our Portsmouth protocol. Methods. During robotic rectal cancer surgery, we used indocyanine green to determine the level of transection and check the vascularity of the circular anastomosis...

OBJECTIVE: Absorbable suture is the preferred method of cesarean skin closure compared with metal staples, because it decreases wound complications. Two recently published trials in patients with obesity contradict this evidence. The goal of this meta-analysis was to assess whether suture remains the recommended method of cesarean skin closure, regardless of obesity status. DATA SOURCES: MEDLINE through OVID, PubMed, Cochrane Database, and ClinicalTrials.gov were searched from inception until September 24, 2021...

INTRODUCTION: One of the main concerns with total hip arthroplasty is the development of periprosthetic joint infections (PJIs). Appropriate wound closure can contribute to the prevention of PJIs with a watertight closure effectively sealing the implant from the outside. It is important to continuously investigate which materials as well as techniques are potentially the most efficacious and cost effective for wound closure. Therefore, the purpose of this review article was to critically appraise the current total hip arthroplasty wound closure materials and techniques as reported in the literature...

OBJECTIVE: To compare the effect of skin closure materials on skin closure during cesarean delivery. METHODS: We searched EMBASE、PubMed、Scopus、Cochrane CENTRAL for randomized controlled trials (RCTs) on the use of closure materials for skin closing effect during cesarean delivery. The outcomes were time to skin closure of dermal and epidermal layer, skin separation rate and wound complications(wound infection, hematoma,seroma, reclosure, readmission) reported as an odds ratio (OR) and surface under the cumulative ranking curve analysis (SUCRA) score...

Background: Learning curves can reflect a surgical trainee's rate of progress and competence in acquiring new skills. The INSORB subdermal staple device has been well established to facilitate decreased closure time across various surgical procedures, with similar cosmesis, healing, and consistency as those of standard subdermal sutures. This study is unique, as it demonstrated an observable learning curve with this device when used by a junior surgeon. Methods: Sixty-six patients underwent a cosmetic procedure during the second half of 2019 under the care of a single plastic surgeon in Melbourne, Australia...

BACKGROUND: Recently, in the field of abdominal wall repair surgery, some minimally invasive procedures introduced the use of staplers to provide a retromuscular prosthetic repair. However, to the knowledge of the authors, there are little data in the literature about the outcomes of stapled sutures adoption for midline reconstruction. This study aims to investigate the biomechanics of stapled sutures, simple (stapled), or oversewn (hybrid), in comparison with handsewn suture. From the results obtained, we tried to draw indications for their use in a clinical context...

OBJECTIVES: The postoperative recurrence rate after thoracoscopic bullectomy for primary spontaneous pneumothorax (PSP) is not satisfactory. This retrospective study was conducted to elucidate an effective technique for improving the postoperative recurrence rate. METHODS: The present study included 373 patients who underwent thoracoscopic bullectomy for PSP at three hospitals from January 2013 to May 2020. We compared the recurrence rate according to two methods that were used to cover the staple line after thoracoscopic bullectomy...

Introduction: Staple-line bleeding and gastric leakage are the most serious complications of laparoscopic sleeve gastrectomy (LSG). Reinforcement of the staple line is reported to be a method to reduce these complications rates, but the question of which method is preferable is a matter of controversy in the literature. In this study, we compared different staple-line reinforcement methods to assess their efficiency in preventing staple-line bleeding and leakage. Materials and Methods: Two hundred patients eligible for LSG were enrolled in the study and randomized into five groups based on the reinforcement method used during surgery: no reinforcement, oversewing using 3-0 polydioxanone (PDS) suture, oversewing using 4-0 barbed absorbable closure device (V-Lock), fibrin sealant glue, and buttress material...

BACKGROUNDS: To compare the clinical effectiveness of different mesh fixation techniques in Lichtenstein tension-free repair using network meta-analysis. METHODS: Cochrane Library, Medline, EMBASE, and Web of Science databases were searched until 1 December 2020, and randomized controlled trials (RCTs) comparing outcomes between different mesh fixation techniques were included. The primary endpoints were chronic postoperative inguinal pain (CPIP) and hernia recurrence...

There is no clear recommendation for wound closure material in foot and ankle surgery. Thus, we hypothesized that there was no difference in clinical outcomes among 3 suture materials, namely, absorbable sutures, nonabsorbable sutures, and metallic staples. This study compared the 3 materials for wound closure in foot and ankle surgery. In this prospective randomized study, 124 patients were randomly divided into the nonabsorbable suture group, absorbable suture group, and staple group. ASEPSIS score, Hollander Wound Evaluation Scale, and numerical rating scale (regarding pain and satisfaction) were collected at first dressing changes, suture removal, and 6 weeks after surgery...

Introduction: Hemorrhoids are a common coloproctology problem and among 10% of cases need surgical intervention. However, the established surgical interventions still have many complications. Case presentation: We reported three female patients, who presented with circular 3rd degree internal hemorrhoids. The surgical treatment was performed with pre-operative anal dilatation using a 33 mm dilator for 20 minutes, followed by triangle incision above the dentate line...
