Enhancing prone positioning and skin damage prevention education: A randomized controlled non-inferiority trial comparing a digital education hub (PRONEtect) and a traditional lecture on final-year nursing participants' confidence and knowledge.

INTRODUCTION: The incidence of pressure ulcers remains high in patients with moderate to severe acute respiratory distress syndrome, ventilated in the prone position. A digital platform, dedicated to prone positioning and skin/tissue damage education was developed. OBJECTIVE: To evaluate the impact of the PRONEtect Education Hub versus a traditional lecture on final-year nursing students' confidence levels and knowledge in a non-inferiority study. DESIGN: A multicenter, non-blinded, parallel-group, non-inferiority study with equal randomization (1:1 allocation) was conducted at two nursing schools in Belgium. CLINICALTRIALS: gov (NCT05575869). METHODS: Following baseline assessments, the control group received a 1-h classroom lecture, and the experimental group gained access to the PRONEtect website. Three weeks later, participants completed the knowledge, confidence, and visual knowledge assessment. RESULTS: At baseline, 67 of the 80 participants completed the assessments and post-intervention, 28 and 27 participants respectively completed the confidence, knowledge, and visual knowledge assessments (dropout rate of 66.25%). Confidence levels: a mean ratio of relative change from baseline = 0.96 (Control (C)/Experimental (E)); 97.5% confidence interval (CI): 0.74 to 1.26; p = 0.74. Knowledge assessment: a mean difference in change from baseline = 1.58 (C-E); 97.5% CI: -0.58 to 3.75; p = 0.1. Although confidence and knowledge scores increased in both groups, the study cannot conclude non-inferiority. CONCLUSIONS: The trade-off between the inability to conclude efficacy of the impact of the website and the benefit of having an accessible educational platform on prone positioning and skin damage prevention makes the PRONEtect Education Hub an acceptable adjunct to traditional lecturing.

Development of prone positioning and skin damage prevention digital education: the PRONEtect project.

OBJECTIVE: The incidence of skin/tissue damage, such as pressure ulcers, remains high in mechanically ventilated patients in the prone position. According to guidelines, critically ill patients with acute respiratory distress syndrome (ARDS) should be prone for at least 12-16 hours to improve oxygenation and decrease mortality. Therefore, educating clinicians on how to reposition and manage the patient safely in a prone position plays a vital role in preventing adverse events. This project aimed to develop accessible online educational content to assist clinicians in safely executing the prone manoeuvre and minimise skin/tissue damage. METHOD: The development of the educational content was based on: a gap analysis and comprehensive review of available educational resources; evidence-based scientific literature; advice from international experts; and a qualitative study exploring the learning needs of 20 clinicians in Belgium and Sweden between February-August 2022. RESULTS: Volunteer clinicians assisted with the creation of eight simulation videos which were professionally filmed and edited. The interactive videos included the supine-to-prone and prone-to-supine manoeuvres, endotracheal and nasogastric tube securement, eye care, stoma care, protecting high-risk areas from pressure damage, and incontinence-associated dermatitis prevention. A prone positioning protocol, a checklist summarising the key aspects of the protocol, and teaching aids (slide deck for didactic lecturing) were developed and validated by a review of the relevant evidence-based literature and the international expert panel. A website was designed to host the content, with free user access, at www.pronetection.com. CONCLUSION: Education is one strategy towards prevention of complications of prone positioning. Accessible education could assist clinicians unfamiliar with prone positioning or current clinicians requiring refresher training to safely manage patients in this position.

Skin damage prevention in the prone ventilated critically ill patient: A comprehensive review and gap analysis (PRONEtect study).

BACKGROUND: Ventilating critically ill patients with acute respiratory distress syndrome in the prone position is a life-saving strategy, but it is associated with adverse consequences such as skin damage. AIM: To identify, review and evaluate international proning and skin care guidelines and make an inventory of commonly used equipment and training resources. DESIGN: A gap analysis methodology was applied. METHODS: 1) Comprehensive search and evaluation of proning and skin care guidelines, 2) extensive search and listing equipment and educational resources, and 3) international consultation with 11 experts (8 countries). DATA SOURCES: A variety of sources researched through July 2021 were used to identify relevant literature: (1) scientific literature databases and clinical trials registries, (2) intensive care and wound care associations, (3) healthcare organisations, (4) guideline development organisations, and (5) the Google search engine. Eleven international experts reviewed the literature and provided insights in two, 2-h online sessions. FINDINGS: The search yielded 24 guidelines. One clinical practice guideline had high methodological quality. Twenty-five devices/equipment and sixteen teaching materials were identified and discussed with the expert panel. The gap analysis identified a lack of concise, accessible, evidence-based guidelines and educational materials of short duration. CONCLUSION: This analysis forms the basis for designing a competency-based education and training intervention for an interdisciplinary team caring for the skin of critically ill patients in the prone position. IMPACT: The results can assist the multidisciplinary team to review their current protocol for prone positioning. This is a first step in developing a training package for clinicians.

Skin tears: prevention and management.

Skin tears commonly occur at the extremes of age and are associated with skin changes in ageing skin. They are considered to be acute wounds caused by mechanical forces, such as blunt trauma. While the true prevalence and incidence of skin tears is unknown, the available evidence suggests that these wounds occur in all healthcare settings. Importantly, skin tears are preventable with the implementation of a risk-reduction programme, which includes twice-daily skin moisturisation. Where these injuries do occur, it is important to categorise the extent of damage as well as to choose the most appropriate dressing to avoid adding any risks for further trauma.

Prevalence of skin tears among frail older adults living in Canadian long-term care facilities.

OBJECTIVES: To explore the prevalence of skin tears in the Canadian long-term care (LTC) population. SUBJECTS AND SETTING: The setting included 678 residents residing in four LTC facilities in western Canada. DESIGN: A cross-sectional prevalence study to establish the prevalence of skin tears in four LTC facilities in Canada. RESULTS: The prevalence of skin tears was 14.7%. Primary associated risk factors included advanced age, being male and having an increased pressure ulcer risk. CONCLUSION: This study was an important step in establishing the burden of skin tears in the Canadian LTC population. Findings supported the International Skin Tear Advisory Panel (ISTAP) risk reduction programme's claim that increases in age and being of the male sex increase the risk for skin tears. The results support a possible link between skin tear risk factors and risk factors associated with pressure ulcers.

Can We Increase the Value and Decrease the Cost of Clinical Skills Assessment?

Although the authors do not agree with medical students' bid to end the United States Medical Licensing Examination Step 2 Clinical Skills or Comprehensive Osteopathic Medical Licensing Examination Level 2-Performance Evaluation tests, they concur with Ecker and colleagues that conducting further research to support the validity argument, providing greater feedback on performance, and exploring options to reduce costs are important for addressing students' concerns. Evidence to support the validity of clinical skills exam scores and associated inferences already exists. What is lacking, and would help further justify the use of these examinations, is more evidence to support the "extrapolation" argument-that is, is performance on these examinations related to actual patient care? Enhanced feedback on exam performance should also be considered. While performance data from licensing examinations should be used judiciously given the primary purpose of these tests, additional data would be helpful to learners and their institutions. Centralized testing remains the least costly design, but efficiencies of standardized patient training, case development, and scoring can be reviewed. Scoring modifications made in the past several years at substantial cost should be evaluated to determine whether they have achieved desired goals. Testing organizations can and should embrace these essential elements of transparency and accountability to address concerns about the value of clinical skills examinations.

Hip fracture: diagnosis, treatment, and secondary prevention.

Hip fractures cause significant morbidity and are associated with increased mortality. Women experience 80% of hip fractures, and the average age of persons who have a hip fracture is 80 years. Most hip fractures are associated with a fall, although other risk factors include decreased bone mineral density, reduced level of activity, and chronic medication use. Patients with hip fractures have pain in the groin and are unable to bear weight on the affected extremity. During the physical examination, displaced fractures present with external rotation and abduction, and the leg will appear shortened. Plain radiography with cross-table lateral view of the hip and anteroposterior view of the pelvis usually confirms the diagnosis. If an occult hip fracture is suspected and plain radiography is normal, magnetic resonance imaging should be ordered. Most fractures are treated surgically unless the patient has significant comorbidities or reduced life expectancy. The consulting orthopedic surgeon will choose the surgical procedure. Patients should receive prophylactic antibiotics, particularly against Staphylococcus aureus, before surgery. In addition, patients should receive thromboembolic prophylaxis, preferably with low-molecular-weight heparin. Rehabilitation is critical to long-term recovery. Unless contraindicated, bisphosphonate therapy should be used to reduce the risk of another hip fracture. Some patients may benefit from a fall-prevention assessment.

Inguinal hernias: diagnosis and management.

Inguinal hernias are one of the most common reasons a primary care patient may need referral for surgical intervention. The history and physical examination are usually sufficient to make the diagnosis. Symptomatic patients often have groin pain, which can sometimes be severe. Inguinal hernias may cause a burning, gurgling, or aching sensation in the groin, and a heavy or dragging sensation may worsen toward the end of the day and after prolonged activity. An abdominal bulge may disappear when the patient is in the prone position. Examination involves feeling for a bulge or impulse while the patient coughs or strains. Although imaging is rarely warranted, ultrasonography or magnetic resonance imaging can help diagnose a hernia in an athlete without a palpable impulse or bulge on physical examination. Ultrasonography may also be indicated with a recurrent hernia or suspected hydrocele, when the diagnosis is uncertain, or if there are surgical complications. Although most hernias are repaired, surgical intervention is not always necessary, such as with a small, minimally symptomatic hernia. If repair is necessary, the patient should be counseled about whether an open or laparoscopic technique is best. Surgical complications and hernia recurrences are uncommon. However, a patient with a recurrent hernia should be referred to the original surgeon, if possible.

Carpal tunnel syndrome.

Carpal tunnel syndrome is the most common entrapment neuropathy, affecting approximately 3 to 6 percent of adults in the general population. Although the cause is not usually determined, it can include trauma, repetitive maneuvers, certain diseases, and pregnancy. Symptoms are related to compression of the median nerve, which results in pain, numbness, and tingling. Physical examination findings, such as hypalgesia, square wrist sign, and a classic or probable pattern on hand symptom diagram, are useful in making the diagnosis. Nerve conduction studies and electromyography can resolve diagnostic uncertainty and can be used to quantify and stratify disease severity. Treatment options are based on disease severity. Six weeks to three months of conservative treatment can be considered in patients with mild disease. Lifestyle modifications, including decreasing repetitive activity and using ergonomic devices, have been traditionally advocated, but have inconsistent evidence to support their effectiveness. Cock-up and neutral wrist splints and oral corticosteroids are considered first-line therapies, with local corticosteroid injections used for refractory symptoms. Nonsteroidal anti-inflammatory drugs, diuretics, and pyridoxine (vitamin B6) have been shown to be no more effective than placebo. Most conservative treatments provide short-term symptom relief, with little evidence supporting long-term benefits. Patients with moderate to severe disease should be considered for surgical evaluation. Open and endoscopic surgical approaches have similar five-year outcomes.

Musculoskeletal disorders.

Musculoskeletal system complaints are one of the most common reasons that patients seek medical care. A significant number of these patients use complementary and alternative medicine. This article discusses the most common musculoskeletal problems for which patients present to a physician's office. These include osteoarthritis, rheumatoid arthritis, low back pain, neck pain, and myofascial pain syndrome.

Fostering rural physicians: the early success of the rural scholars track at Louisiana State University Health Sciences Center School of Medicine--New Orleans.

Louisiana is a predominantly rural state, with 86 percent of its parishes classified as areas of Primary Care Health Professional Shortages by the US Department of Health and Human Services. As a result, individuals living in these areas have limited access to primary medical care. In addition, data derived from the Association of American Medical Colleges Center for Workforce Studies clearly indicate that fewer and fewer medical-school graduates are choosing primary-care specialties as a career. This national trend has been noted here at the Louisiana State University Health Sciences Center (LSUHSC) School of Medicine - New Orleans. In order to address this decline, the School of Medicine created the Rural Scholars Track with the objective of producing primary-care physicians for Louisiana, in particular for rural areas. While the program is still in its early years, the results have been positive and hold hope for the future of health care in the state.

Common spider bites.

There are more than 30,000 species of spiders, most of which cannot inflict serious bites to humans because of their delicate mouthparts and impotent or prey-specific venoms. However, some spiders produce toxic venoms that can cause skin lesions, systemic illnesses, and neurotoxicity. One of the more common bites is inflicted by the widow spiders (Latrodectus species). A bite from a widow spider results in muscle spasms and rigidity starting at the bite site within 30 minutes to two hours. Another common bite is inflicted by the recluse spider (Loxosceles species). Most bites from these spiders occur early in the morning and are initially painless. These bites usually progress to ulcerating dermonecrosis at the bite site. Spider bites can be prevented by simple measures. Early species identification and specific management can prevent most serious sequelae of spider bites.

Effects of 4-hydroxytamoxifen, raloxifene and ICI 182 780 on survival of uterine cancer cell lines in the presence and absence of exogenous estrogens.

The impact of 17beta-estradiol and antiestrogens on uterine cancer cells is poorly understood. The aim of this study was to determine the impact of 17beta-estradiol, 4-hydroxytamoxifen, raloxifene and ICI 182 780 on the cell proliferation of six uterine cancer cell lines: HeLa, HEC-1-A, KLE, RL-95-2, Ishikawa and EN-1078D. The effects of these compounds on the cell proliferation of the six uterine cancer cell lines were studied in the presence and absence of estrogens (phenol red and serum deprivation of sex steroids). In a general manner, 17beta-estradiol and 4-hydroxytamoxifen showed similarities in their effects whereas raloxifene showed a different pattern of cell proliferation (agonistic and antagonistic) and ICI 182 780 had antagonistic activity. In the presence and absence of estrogens, we observed that each cell line had diverse expression of ERalpha, ERbeta, GPR30 and REA. GPR30 mRNA expression was significantly reduced in a serum/phenol-free medium. REA mRNA expression was not influenced by the media. Results demonstrated the importance of removing phenol red and the use of deprived serum when studying uterine cancer cells in relationship with 17beta-estradiol and antiestrogens. The affinity of each compound to the binding of ERalpha and ERbeta was very similar with the exception of raloxifene that had a preference for ERalpha binding. Akt phosphorylation/activity was reduced in cells cultured in a phenol red- and steroid-free culture medium indicating that the presence of steroids in the culture media can influence the activity of this survival pathway. Our results suggest that the expression of ERalpha, ERbeta and GPR30 are influenced by sex steroids and might play a role in the response of cells to 17beta-estradiol and antiestrogens but are not the only factors involved in this process.

Resveratrol interferes with AKT activity and triggers apoptosis in human uterine cancer cells.

BACKGROUND: Endometrial cancer is the fourth most prominent cancer among all feminine cancers in the Western world. Resveratrol, a natural anti-oxidant found in red wine emerging as a novel anticancer agent, exerts antiproliferative and pro-apoptotic activity in various cancer cell types, but its effect on uterine cancer cells is poorly understood. At the molecular level, resveratrol has been reported to inhibit cyclooxygenase (COX) expression and/or activity; in endometrial cancer cells, COX-2 is overexpressed and confers cellular resistance to apoptosis. The aim of the present study was to determine if resveratrol could exert anti-proliferative and pro-apoptotic activity over uterine cancer cells upon inhibition of COX-2 expression and/or activity. Six different human uterine cancer cell lines were used as a model (HeLa, Hec-1A, KLE, RL95-2, Ishikawa and EN-1078D). RESULTS AND DISCUSSION: High-dose of resveratrol triggered apoptosis in five out of six uterine cancer cell lines, as judged from Hoechst nuclear staining and effector caspase cleavage. In accordance, uterine cancer cell proliferation was decreased. Resveratrol also reduced cellular levels of the phosphorylated/active form of anti-apoptotic kinase AKT. Endogenous COX-2 protein levels were decreased, concomitant with a decrease in production of COX metabolites PGE2 and PGF2alpha, in each uterine cancer cell line expressing detectable levels of COX-1 and/or COX-2 in presence of resveratrol. Although COX expression was identified as a target of resveratrol in uterine cancer cells, inhibition of COX activity or exogenously added PGE2 did not modulate the effect of resveratrol on cellular proliferation. CONCLUSION: High-dose of resveratrol exerts tumoricidal activity over uterine cancer cells and regulates COX expression. In these cells, resveratrol would not directly target COX activity, but possibly other enzymes involved in prostaglandin synthesis that act downstream of the COXs.

Ankle problems masquerading as sprains.

The most common ankle injury is a ligamentous sprain, usually involving the lateral side. This is usually treated very successfully with conservative management. Those patients who have continued complaints despite such management should be suspected of having something more than a simple sprain. The diagnostic entities discussed herein should always be part of the differential diagnosis of a sprained ankle, so that when one of these injuries is initially missed, the examining physician will be able to re-examine and eventually diagnose and treat these injuries properly. They should be managed appropriately as soon as possible for the best outcome. Needless delays should be avoided.

AKT involvement in cisplatin chemoresistance of human uterine cancer cells.

OBJECTIVE: The aim of this study was to investigate the possible involvement of Akt activity and specific isoforms (Akt1, Akt2, and Akt3) in the resistance of human uterine cancer cells to cisplatin. METHODS: Two different endometrial (HEC-1-A and KLE) and one cervical (HeLa) cancer cell lines all known as wild-type PTEN (tumor suppressor phosphatase tensin homologue, a lipid phosphatase involved in the negative regulation of Akt activity) were used for these studies. RESULTS: Basal levels of Akt1, Akt2, and Akt3 mRNAs were determined by real-time quantitative RT-PCR studies and Western blot analyses were carried out to determine protein abundance of each isoforms. Akt1 mRNA and protein were present in all cell lines studied. Akt2 and Akt3 mRNAs and proteins were strongly expressed in KLE cells. Surprisingly, Akt phosphorylation was found in KLE expressing high levels of wild-type PTEN protein. KLE cells remained resistant to PI 3-K inhibitor, indicating that Akt phosphorylation might be, in part, independent of PI 3-K in this cell line. Cisplatin induced apoptosis in HeLa and HEC-1-A cells, but KLE cells expressing Akt2 and Akt3 remained more resistant to cisplatin. Knockout of Akt isoforms using specific siRNA technology increased the sensitivity of KLE cells toward cisplatin and caused a significant induction of cell death. CONCLUSION: Taken together, these results suggest that specific Akt isoforms such as Akt2 and Akt3 might be involved in chemoresistance to cisplatin and that these isoforms could be putative targets for gene therapy in uterine cancers.

Groin pain in athletes.

Groin pain in athletes is not infrequently a cause of frustration and aggravation to both doctor and patient. Complaints in the groin region can prove difficult to diagnose, particularly when they are of a chronic nature. These injuries are seen more commonly in sports that require specific use (or overuse) of the proximal musculature of the thigh and lower abdominal muscles. Some of the more common sports would be soccer, skiing, hurdling, and hockey. The differential diagnosis can cover a rather broad area of possibilities. Most common groin injuries are soft-tissue injuries, such as muscular strains, tendinitis, or contusions. More difficult areas to pinpoint are such entities as osteitis pubis, nerve entrapment, the so-called "sports hernia," or avulsion fractures, to name but a few. The evaluation of such patients includes a familiarity with the sport and possible mechanism of injury (i.e., taking a careful history), meticulous physical examination of the groin, abdomen, hips, spine, and lower extremities. Diagnostic examinations may or may not prove helpful in formulating a final diagnosis. Some patients may be required to undergo procedures, such as laparoscopic evaluation of the region to obtain adequate information that allows a proper diagnosis and treatment plan. This article describes many of the possible causes of groin pain in athletes. The list is quite lengthy, and only the more common problems will be discussed in detail.
