Purpose: Although the number of older adults who might benefit from kidney transplantation continues to increase in the United states, little is known about older adults' lived experience of transplantation and the impact of transplant on their sense of embodied selfhood.
Method(s): Employing a phenomenological research design, this study explored the lived experience of 10 deceased donor kidney transplant recipients aged 65 to 72 years old. Participants completed one to two in-depth phenomenological interviews lasting approximately one hour each, for a total of 15 interviews. The sample was drawn from a transplant center in an urban location in the United States. Interview transcripts and field notes were analyzed following the processes of phenomenological reduction, imaginative variation and synthesis.
Result(s): Analyses illuminated older adults' perceptions of the impact of kidney transplantation on their sense of physical, psychological and social selfhood. Participants reported experiencing physical and psychosocial challenges as they adjusted to their transplants, yet they also constructed powerful narratives of resilience and coping that were rooted in a deeply held sense of identity developed over the life course. This sense of continuity of the embodied self over time enabled most participants to better navigate the corporeal disruption and re-integration of transplantation. Participants expressed profound appreciation for their transplants and reported substantial improvement in quality of life as compared to their pre-transplant experience on dialysis. Most participants perceived their older age as playing a protective role in the recovery process.
Conclusion(s): These findings shed light on benefits of older age for kidney transplant recipients that may not be fully integrated into standard approaches to patient selection and assessment of transplant outcomes. As such, findings may help to address age-related bias in transplant policy and clinical practice, with the ultimate goal of improving wellbeing and quality of life for older adults

BACKGROUND:Incision planning is a critical factor in nipple-sparing mastectomy outcomes. Evidence on optimal incision patterns in patients undergoing nipple-sparing mastectomy and immediate microvascular breast reconstruction is lacking in the literature. METHODS:A single-institution retrospective review was performed of consecutive patients undergoing nipple-sparing mastectomy and immediate microvascular autologous reconstruction from 2007 to 2019. Outcomes-including major mastectomy flap necrosis, full nipple-areola complex necrosis, and any major ischemic complication of the skin envelope-were compared among incision types. Multivariable logistic regression identified factors associated with major ischemic complication. RESULTS:Two hundred seventy-nine reconstructions (163 patients) were identified, primarily using internal mammary recipient vessels (98.9 percent). Vertical incisions were used in 139 cases; inframammary, in 53; lateral radial, in 51; and inverted-T, in 35. Thirty-two cases (11.5 percent) had major mastectomy flap necrosis, 11 (3.9 percent) had full nipple-areola complex necrosis, and 38 (13.6 percent) had any major ischemic complication. Inframammary incisions had higher rates of major ischemic complication (25 percent) than vertical (5.8 percent; p < 0.001) and lateral radial (7.8 percent; p = 0.032) incisions. Inverted-T incisions also had higher rates of major ischemic complication (36.1 percent) than both vertical (p < 0.001) and lateral radial (p = 0.002) incisions. Inframammary incisions (OR, 4.382; p = 0.002), inverted-T incisions (OR, 3.952; p = 0.011), and mastectomy weight (OR, 1.003; p < 0.001) were independently associated with an increased risk of major ischemic complication. Inframammary incisions with major ischemic complication demonstrated significantly higher body mass index, mastectomy weight, and flap weight compared to those without. CONCLUSIONS:Inframammary and inverted-T incisions are associated with a higher risk of major ischemic skin envelope complications after nipple-sparing mastectomy and immediate microvascular breast reconstruction. Radial incisions can be considered to optimize recipient vessel exposure without compromising perfusion. CLINICAL QUESTION/LEVEL OF EVIDENCE/METHODS:Therapeutic, III.

As more young people feel safe to outwardly identify as transgender or gender expansive (TGE), meaning that their gender identity does not align with the sex they were assigned at birth, an increasing number of youth who identify as TGE seek gender-affirming medical care (GAMC). GAMC raises a number of ethical questions, such as the capacity of a minor to assent or consent, the role of parents or legal guardians in decisions about treatment, and implications for equitable access to care when differing parental or custodial viewpoints are present. These questions are further complicated by the difficulties in explaining the limits of long-term research in GAMC, with regard to the preservation of fertility, for example. We present two de-identified composite case studies to highlight dilemmas that may arise and offer recommendations to better support patient- and family-centered decision making for GAMC. These include employing a multidisciplinary shared decision-making approach, disentangling informed consent and assent from chronological age, developing a consistent approach to the assessment of decisional capacity, and developing age-appropriate informational materials.

Pain is one of the most common medical conditions and affects more Americans than diabetes, heart disease, and cancer combined. Current pain treatments mainly rely on opioid analgesics and remain unsatisfactory. The life-threatening side effects and addictive properties of opioids demand new therapeutic approaches. Nanomedicine may be able to address these challenges as it allows for sensitive and targeted treatments without some of the burdens associated with current clinical pain therapies. This review discusses the physiology of pain, the current landscape of pain treatment, novel targets for pain treatment, and recent and ongoing efforts to effectively treat pain using nanotechnology-based approaches. We highl ight advances in nanoparticle-based drug delivery to reduce side effects, gene therapy to tackle the source of pain, and nanomaterials-based scavenging to proactively mediate pain signaling.

Regional blocks are being increasingly utilized for anesthesia for various orthopedic procedures. Several studies have shown that regional anesthesia has fewer side effects and improved postoperative pain relief compared to general anesthesia, but regional blocks are not without risks. We present case reports of 2 patients who experienced posterior shoulder instability, one of whom had a posterior shoulder dislocation, immediately in the postanesthesia care unit after undergoing hand surgery with regional anesthesia. This paper highlights the importance of being aware that patients might be at increased risk of shoulder instability after upper extremity regional anesthesia, and appropriate perioperative precautions should be taken.

Major peripheral nerve injuries are devastating and represent a very challenging clinical problem. Despite many years of advancement in peripheral nerve research, results so far have been fair at best, with only 50% of patients regaining useful function. Advancement of techniques in imaging, better understanding of the physiology of nerve recovery, improved repair and grafting options, and secondary reconstructive techniques, including tendon and nerve transfers, have helped facilitate a degree of more effective treatment. This article presents current concepts regarding the principles of management, expected outcomes, and new advancements in major upper extremity peripheral nerve injuries.

GENERAL PURPOSE/UNASSIGNED:To provide information about arginine, its metabolism, and its role in acute and chronic wound healing, to assist providers in understanding the recommendations for arginine supplementation. TARGET AUDIENCE/BACKGROUND:This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES/UNASSIGNED:After participating in this educational activity, the participant will:1. Describe the characteristics of arginine.2. Choose the metabolic processes that define arginine's role in wound healing.3. Identify the average daily intake of arginine in an American diet.4. Select the evidence that demonstrates the effectiveness of arginine supplementation for wound healing. ABSTRACT/UNASSIGNED:Nutrition has an important and integral role in wound healing. Arginine, a type of indispensable amino acid, has long been thought to have wound healing properties. The 2019 international guideline by the European Pressure Ulcer Advisory Panel, National Pressure Injury Advisory Panel, and Pan Pacific Pressure Injury Alliance recommends use of a high-protein, high-calorie oral nutrition supplement fortified with arginine and other antioxidants to treat adults with stage 2 or greater pressure injury and who are malnourished or at risk of malnutrition to foster healing. This article provides necessary background on this conditionally indispensable amino acid, its metabolism, and its role in acute and chronic wound healing to assist providers in understanding the recommendation for arginine supplementation.
