GENERAL PURPOSE: To review the nutrition-related recommendations presented in the 2019 European Pressure Ulcer Advisory Panel, National Pressure Injury Advisory Panel, and Pan Pacific Pressure Injury Alliance Prevention and Treatment of Pressure Ulcers/Injuries: Clinical Practice Guideline with further discussion of nutrition for pressure injury management in the context of the recommendations. TARGET AUDIENCE: 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: After participating in this educational activity, the participant should be better able to:1. Distinguish nutrition and malnutrition, especially as they relate to the development and healing of pressure injuries.2. Differentiate the tools and techniques that help clinicians assess nutrition status as well as the causes of pressure injuries in specific populations.3. Identify interventions for improving nutrition status and promoting pressure injury healing. ABSTRACT: Macro- and micronutrients are required by each organ system in specific amounts to promote the growth, development, maintenance, and repair of body tissues. Specifically, nutrition plays an important role in the prevention and treatment of pressure injuries. The purpose of this manuscript is to review the nutrition-related recommendations presented in the 2019 European Pressure Ulcer Advisory Panel, National Pressure Injury Advisory Panel, and Pan Pacific Pressure Injury Alliance Prevention and Treatment of Pressure Ulcers/Injuries: Clinical Practice Guideline. Nutrition for pressure injury management is discussed in the context of the recommendations.

Serum concentration of hepatic enzymes are linked to liver dysfunction, metabolic and cardiovascular diseases. We perform genetic analysis on serum levels of alanine transaminase (ALT), alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT) using data on 437,438 UK Biobank participants. Replication in 315,572 individuals from European descent from the Million Veteran Program, Rotterdam Study and Lifeline study confirms 517 liver enzyme SNPs. Genetic risk score analysis using the identified SNPs is strongly associated with serum activity of liver enzymes in two independent European descent studies (The Airwave Health Monitoring study and the Northern Finland Birth Cohort 1966). Gene-set enrichment analysis using the identified SNPs highlights involvement in liver development and function, lipid metabolism, insulin resistance, and vascular formation. Mendelian randomization analysis shows association of liver enzyme variants with coronary heart disease and ischemic stroke. Genetic risk score for elevated serum activity of liver enzymes is associated with higher fat percentage of body, trunk, and liver and body mass index. Our study highlights the role of molecular pathways regulated by the liver in metabolic disorders and cardiovascular disease.

OBJECTIVE: To determine whether a comprehensive diabetes management program that included risk stratification and social marketing would improve clinical outcomes and patient satisfaction within a managed care organization (MCO). RESEARCH DESIGN AND METHODS: The 12-month prospective trial was conducted at primary care clinics within a MCO and involved 370 adults with diabetes. Measurements included 1) the frequency of dilated eye and foot examinations, microalbuminuria assessment, blood pressure measurement, lipid profile, and HbA(1c) measurement; 2) changes in blood pressure, lipid levels, and HbA(1c) levels; and 3) changes in patient satisfaction. RESULTS: Complete data are reported for the 193 patients who had been enrolled for 12 months; life table analysis is reported for all patients who remained enrolled at the study's end as well as for a comparative control group of 623 patients. For the 193 patients for whom 12-month data were available, the number of patients in the low-risk category (HbA(1c) <7%) increased by 51.1%. A total of 97.4% of patients with an HbA(1c) >8% at baseline had a change in treatment regimen. Patients at the highest risk for coronary heart disease (LDL >130 mg/dl) decreased from 25.4% at baseline to 20.2%. Patients with a blood pressure <130/85 mmHg increased from 23.8 to 44.6%. Of these patients, 63.0% had changes in medication. Patients and providers expressed significant increases in satisfaction with the program. CONCLUSIONS: The program was successful in initiating the recommended changes in the diabetic therapeutic regimen, resulting in improved glycemic control, increased monitoring/management of diabetic complications, and greater patient and provider satisfaction. These results should have great significance in the design of future programs in MCOs aimed at improving the care of people with diabetes and other chronic diseases.

Obstructive sleep apnea (OSA) is the most common form of sleep-disordered breathing, affecting 5-15% of the population. It is characterized by intermittent episodes of partial or complete obstruction of the upper airway during sleep that disrupts normal ventilation and sleep architecture, and is typically associated with excessive daytime sleepiness, snoring, and witnessed apneas. Patients with obstructive sleep apnea present risk to the general public safety by causing 8-fold increase in vehicle accidents, and they may themselves also suffer from the physiologic consequences of OSA; these include hypertension, coronary artery disease, stroke, congestive heart failure, pulmonary hypertension, and cardiac arrhythmias. Of these possible cardiovascular consequences, the association between OSA and hypertension has been found to be the most convincing. Although the exact mechanism has not been understood, there is some evidence that OSA is associated with frequent apneas causing mechanical effects on intrathoracic pressure, cardiac function, and intermittent hypoxemia, which may in turn cause endothelial dysfunction and increase in sympathetic drive. Therapy with continuous positive airway pressure has been demonstrated to improve cardiopulmonary hemodynamics in patients with OSA and may reverse the endothelial cell dysfunction. Despite the availability of diagnostic measures and effective treatment, many patients with sleep-disordered breathing remain undiagnosed. Therefore, OSA continues to be a significant health risk both for affected individuals and for the general public. Awareness and timely initiation of an effective treatment may prevent potential deleterious cardiovascular effects of OSA.

BACKGROUND: Patients with irritable bowel syndrome with diarrhoea (IBS-D) experience restriction in daily activities and decreased health-related quality of life (QOL). AIM: To investigate effects of alosetron on patient-reported health-related QOL, satisfaction and productivity in women with severe IBS-D. METHODS: A total of 705 women (severe IBS-D, Rome II criteria) randomised to alosetron 0.5 mg QD, 1 mg QD, 1 mg BID, or placebo for 12 weeks were studied. IBSQOL, treatment satisfaction, daily activities, and lost workplace productivity (LWP) were evaluated at randomisation and Week 12. RESULTS: One or more doses of alosetron significantly improved all IBSQOL domains except for sexual function from baseline vs. placebo. The magnitude of IBSQOL changes was consistent with a clinically meaningful effect. Alosetron 0.5 mg QD and 1 mg BID significantly reduced IBS interference with social/leisure activities and LWP from baseline vs. placebo [social/leisure (mean ±S.E.) days lost: -6.7 ± 0.8, -7.0 ± 0.9, P < 0.01; LWP (mean ± S.E.) h lost: -11.0 ± 3.3, -21.1 ± 4.1, P < 0.05 respectively]. Significantly more patients treated with alosetron reported satisfaction vs. placebo. Improvements in IBSQOL, LWP, and treatment satisfaction significantly correlated with global improvement of IBS symptoms. The incidence of adverse events with alosetron was low with constipation being the most commonly reported event. A single case of ischaemic colitis occurred, in a patient receiving alosetron 0.5 mg QD. CONCLUSIONS: In women with severe IBS-D, alosetron treatment, including 0.5 mg QD, resulted in statistically significant and clinically relevant improvements in health-related QOL, restriction of daily activities and treatment satisfaction over placebo. IBS symptom improvement corresponded with positive changes in IBSQOL, LWP and treatment satisfaction.

It has been suggested that tooth loss in later life might increase dementia incidence. The objective of this analysis is to systematically review the current evidence on the relationship between the number of remaining teeth and dementia occurrence in later life. A search of multiple databases of scientific literature was conducted with relevant parameters for articles published up to March 25th, 2017. Multiple cohort studies that reported the incidence of dementia and residual teeth in later life were found with observation periods ranging from 2.4 to 32 years. Random-effects pooled odds ratios (OR) and 95% confidence intervals (CI) were estimated to examine whether high residual tooth number in later life was associated with a decreased risk of dementia. Heterogeneity was measured by I2. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used to assess the overall quality of evidence. The literature search initially yielded 419 articles and 11 studies (aged 52 to 75 at study enrollment, n = 28,894) were finally included for analysis. Compared to the low residual teeth number group, the high residual teeth number group was associated with a decreased risk of dementia by approximately 50% (pooled OR = 0.483; 95% CI 0.315 to 0.740; p < 0.001; I2 = 92.421%). The overall quality of evidence, however, was rated as very low. Despite limited scientific strength, the current meta-analysis reported that a higher number of residual teeth was associated with having a lower risk of dementia occurrence in later life.

A survey of community-based outpatient clinic health care providers suggests the need for additional education and training to increase their cultural competencies.

Strongyloidiasis is epidemic in tropical and subtropical regions where the regional prevalence may exceed 25%. In the United States, highest infection rates are found in immigrants. Many infected individuals are asymptomatic, whereas others may have mild and nonspecific cutaneous, intestinal, and pulmonary symptoms. Strongyloides stercoralis may remain as a dormant infection, but replication and dissemination can be fatal in immunocompromised patients. We report on a 63-year-old native Filipino man with a history of rheumatoid arthritis who developed Escherichia coli sepsis, filariform larvae characteristic of S. stercoralis bronchoalveolar lavage, and adult respiratory distress syndrome 3 weeks after he presented with vague gastrointestinal symptoms. We believe that the addition of a tumor necrosis factor (TNF)-alpha inhibitor to his treatment with prednisone and methotrexate for rheumatoid arthritis further suppressed his cellular immunity leading to hyperinfection and life-threatening S. stercoralis infection. This is another, often latent, infection that should be considered in patients in or from endemic areas before institution of antitumor necrosis factor therapy.

Abstract Introduction: Conducting an accurate suicide risk assessment (SRA) is no simple task as there are a number of factors that influence an individual's level of suicidality and his/her willingness to share this information. Therefore, it is imperative that practitioners adopt a systematic approach to conducting and documenting the foreseeability that a patient will commit suicide. Methods PubMed was used to search for articles published in MEDLINE journals using the following keywords: suicide, risk assessment, measure, scale. Randomized trials and pilot, proof-of-concept publications investigating the use of specific SRA measurements were included in the review. The scales are described based on the prevailing opinions in psychiatry from the American Psychiatric Association's Textbook of Suicide Assessment and Management (2nd ed., 2012). Results Although various SRA scales exist, experts in the field have repeatedly concluded that there is not any one scale that can predict who will commit suicide to any useful degree. However, when used along with the clinical interview, standardized suicide risk factor components of clinical and research scales remain crucial to gaining information often omitted by patients regarding thoughts and preparation for suicide. A summary of the most widely cited scales and approaches used in SRA is provided. Discussion SRA remains a challenge largely due to the fact that suicidal behavior is multifactorial. As a result, risk formulation is a process that should involve both standardized measures and detailed clinical interviews repeated over time.

Sickle cell trait is a relatively common condition in the African-American population. Individuals with this condition may have any of several complications under rare circumstances. We report a patient who presented with extensive compartment syndrome leading to death. A 31-year-old African-American male with known history of sickle cell trait developed extensive compartment syndrome followed by rhabdomyolysis, severe acidosis, acute renal failure, and coagulopathy. Although the patient underwent multiple fasciotomies for extensive compartment syndrome and received aggressive resuscitation with massive transfusions of blood, blood products and intravenous fluids, he died. Multiple compartment syndromes in patients with sickle cell trait represent a very unusual complication and can cause significant morbidity and mortality. Avoidance of strenuous exercise, especially in hot climates, early diagnosis, and aggressive therapy are very important to prevent this catastrophic complication.

Nutrition is an important component in the prevention and treatment of pressure injuries (PIs). The skin is the largest organ of the body, and macronutrients and micronutrients in specific amounts are required to maintain and repair body tissues. The European Pressure Ulcer Advisory Panel, the National Pressure Injury Advisory Panel, and the Pan Pacific Pressure Injury Alliance Prevention and Treatment of Pressure Ulcers/Injuries: 2019 Clinical Practice Guideline includes nutrition recommendations for PI management. This manuscript identifies the key nutrients required for wound healing, reviews the evidence in the 2019 nutrition recommendations, and translates the recommendations provided into key points to be incorporated into policy and practice that impact patient outcomes.

As a distinct type of aggressive mature large B-cell lymphoma, plasmablastic lymphoma (PBL) poses diagnostic and treatment challenges. PBL is distinguished from other B-cell lymphomas by the presence of plasmacytic differentiation markers such as CD38, CD138, and MUM1. Clinically, PBLs from oral and extra-oral sites are rapidly progressive tumors with frequent relapse after treatment with standard diffuse large B-cell lymphoma regimens. Here, we report a near-complete response of one patient with relapsed PBL following treatment with a non-cytotoxic regimen containing bortezomib, rituximab, and dexamethasone.

COVID-19 has infected millions of patients and impacted healthcare workers worldwide. Personal Protective Equipment (PPE) is a key component of protecting frontline clinicians against infection. The benefits of PPE far outweigh the risks, nonetheless, many clinicians are exhibiting skin injury caused by PPE worn incorrectly. These skin injuries, ranging from lesions to open wounds are concerning because they increase the susceptibility of viral infection and transmission to other individuals. Early into the COVID-19 pandemic (April 2020), the U. S. National Pressure Injury Advisory Panel (NPIAP) developed a series of position statements to improve wear-ability of PPE and protect healthcare professionals and their patients as safe from harm as possible under the circumstances. The NPIAP positions, which were formed by conducting a systematic review of what was known at the time, include: (a) Prepare skin before and after wearing PPE with skin sealants, barrier creams and moisturisers; (b) Frequent PPE offloading to relieve pressure and shear applied to skin; (c) treat visible skin injuries immediately caused by PPE to minimise future infection; (d) non-porous dressings may provide additional skin protection, but lack evidence; (e) health systems should take care to educate clinicians about placement and personal hygiene related to handling PPE. Throughout all of these practices, handwashing remains a top priority to handle PPE. These NPIAP positions provided early guidance to reduce the risk of skin injury caused by PPE based on available research regarding PPE injuries, a cautious application of evidence-based recommendations on prevention of device-related pressure injuries in patients and the expert opinion of the NPIAP Board of Directors. Clinicians who adhere to these recommendations reduce the prospects of skin damage and long-term effects (e.g. scarring). These simple steps to minimise the risk of skin injury and reduce the risk of coronavirus infection from PPE can help.

Drinking water ozone disinfection systems measure ozone residual concentration, C, for regulatory compliance reporting of concentration-times-time (CT), and the resultant log-inactivation of virus, Giardia and Cryptosporidium. The indigotrisulfonate (ITS) colorimetric procedure is the Standard Method for measuring ozone residual. Although the currently written Standard Method is relatively easy to implement, its accuracy depends on specific ITS quality control considerations. The Standard Method is based upon specific quantities of materials and sample volumes, which make it somewhat inflexible. Tests are often performed in plant surroundings by operating staff, as opposed to in certified laboratories by analytical chemists. In this paper, a more flexible, quality-assured and “operator-friendly” technique is presented for the ITS method. This manuscript investigates several aspects of the ITS method (e.g. effects of aging, storage temperature, ITS supplier, accuracy of ITS weight measurement, and manganese interference), which are intended to improve the quality assurance and quality control (QA/QC) of the dissolved ozone measurement. Results are presented that document the negative consequences for ignoring certain conditions. For example, ITS solution stored on a shelf for several days can cause an appreciable under-estimation of ozone residual, while storage for several weeks can cause a major under-estimation of ozone residual. Other special study results suggest that greater flexibility is possible for reagent strength, without negative consequence, as compared to the recommended strength that is currently outlined in Standard Methods.

BACKGROUND: Diabetes is a well-known growing epidemic, but prediabetes is increasing at an even greater rate. Lifestyle changes are effective tools to prevent the progression of prediabetes to diabetes, yet many people are unable to follow such changes. Salsalate has been suggested as a possible treatment for diabetes as early as 1876 and as recently as in a 2013 study. OBJECTIVE: To review the recently published evidence about the potential therapeutic benefits of the old drug salsalate for individuals who meet the criteria of having prediabetes. DISCUSSION: With the rising incidence of obesity and prediabetes, it has become prudent to look for more therapeutic options. Salsalate belongs to the salicylate drug class, which has been shown to inhibit I-κB kinase, thereby inhibiting the nuclear factor-κB (NF-κB) cascade and decreasing the production of inflammatory cytokines, as well as decreasing insulin resistance. Recent short-term clinical trials have shown that 3 g to 4.5 g of salicylate therapy daily has the ability to lower insulin resistance and to reduce the levels of glucose, triglycerides, and free fatty acid concentrations through regulation of the I-κB kinase beta/NF-κB pathway, with few if any side effects. However, the effectiveness of salsalate as a treatment option for prediabetes is largely unrecognized. This article summarizes the current evidence from 3 studies of salsalate therapy in the setting of the prediabetic population and presents the case for its use in this population. CONCLUSION: As shown in this review, salsalate therapy at the dose of 3 g to 4.5 g daily can lower insulin resistance and reduce the levels of glucose, triglycerides, and free fatty acid concentrations with minimal side effects. This inexpensive medication could be a useful option in the treatment of prediabetes. Larger clinical trials are needed, but the data are encouraging and should lay the foundation for further investigation and grant funding.

Background: Palliative care services and life-sustaining treatments are provided to dying patients with lung cancer in the United States. However, data on the utilization trends of palliative care services and life-sustaining treatments of dying patients with lung cancer are not available. Methods: This study was a retrospective analysis of the National Inpatient Sample data (2005-2014) and included patients with lung cancer, aged ≥ 18 years, who died in the hospitals. Claims data of palliative care services and life-sustaining treatments that contained systemic procedures, local procedures, or surgeries were extracted. Compound annual growth rates (CAGRs) using Rao-Scott correction for χ 2 tests were used to determine the statistical significance of temporal utilization trends of palliative care services and life-sustaining treatments and their hospital costs. Multilevel multivariate regressions were performed to identify factors associated with hospital costs. Results: A total of 120 144 weighted patients with lung cancer died in the hospitals and 41.9% of them received palliative care services. The CAGRs of systemic procedures, local procedures, surgeries, palliative care services, and hospital cost were 3.42%, 3.48%, 6.08%, 18.5%, and 5.0% (all P &lt; .001), respectively. Increased hospital cost was attributed to systemic procedures (50.6%), local procedures (74.4%), and surgeries (68.5%; all P &lt; .001), respectively. Palliative care services were related to decreasing hospital costs by 28.6% ( P &lt; .001). Conclusion: The temporal trends of palliative care services indicate that their utilization has increased gradually. Palliative care services were associated with reduced hospital costs. However, life-sustaining treatments were associated with increased hospital costs.

We aim to examine temporal trends of orthopedic operations and opioid-related hospital stays among seniors in the nation and states of Oregon and Washington where marijuana legalization was accepted earlier than any others.As aging society advances in the United States (U.S.), orthopedic operations and opioid-related hospital stays among seniors increase in the nation.A serial cross-sectional cohort study using the healthcare cost and utilization project fast stats from 2006 through 2015 measured annual rate per 100,000 populations of orthopedic operations by age groups (45-64 vs 65 and older) as well as annual rate per 100,000 populations of opioid-related hospital stays among 65 and older in the nation, Oregon and Washington states from 2008 through 2017. Orthopedic operations (knee arthroplasty, total or partial hip replacement, spinal fusion or laminectomy) and opioid-related hospital stays were measured. The compound annual growth rate (CAGR) was used to quantify temporal trends of orthopedic operations by age groups as well as opioid-related hospital stays and was tested by Rao-Scott correction of χ for categorical variables.The CAGR (4.06%) of orthopedic operations among age 65 and older increased (P < .001) unlike the unchanged rate among age 45 to 64. The CAGRs of opioid-related hospital stays among age 65 and older were upward trends among seniors in general (6.79%) and in Oregon (10.32%) and Washington (15.48%) in particular (all P < .001).Orthopedic operations and opioid-related hospital stays among seniors increased over time in the U.S. Marijuana legalization might have played a role of gateway drug to opioid among seniors.

Chronic constipation is a common disorder in the general population, with higher prevalence in the elderly, and is associated with worse quality of life and with greater health care utilization. Lubiprostone is an intestinal type-2 chloride channel activator that increases intestinal fluid secretion, small intestinal transit, and stool passage. Lubiprostone is currently approved by the US Food and Drug Administration for the treatment of chronic idiopathic constipation and of irritable bowel syndrome with predominant constipation. This review outlines current approaches and limitations in the treatment of chronic constipation in the elderly and discusses the results, limitations, and applicability of randomized, controlled trials of lubiprostone that have been conducted in the general and elderly population, with additional focus on the use of lubiprostone in constipation in Parkinson's disease and in opioid-induced constipation, two clinical entities that can be comorbid in elderly patients.

BACKGROUND AND OBJECTIVES: Infection is the most common cause of death in severe AKI, but many patients receiving continuous RRT do not reach target antibiotic concentrations in plasma. Extended infusion of β-lactams is associated with improved target attainment in critically ill patients; thus, we hypothesized that extended infusion piperacillin-tazobactam would improve piperacillin target attainment compared with short infusion in patients receiving continuous RRT. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted an institutional review board-approved observational cohort study of piperacillin-tazobactam pharmacokinetics and pharmacodynamics in critically ill patients receiving continuous venovenous hemodialysis and hemodiafiltration at three tertiary care hospitals between 2007 and 2015. Antibiotic concentrations in blood and/or dialysate samples were measured by liquid chromatography, and one- and two-compartment pharmacokinetic models were fitted to the data using nonlinear mixed effects regression. Target attainment for piperacillin was defined as achieving four times the minimum inhibitory concentration of 16 μg/ml for >50% of the dosing cycle. The probabilities of target attainment for a range of doses, frequencies, and infusion durations were estimated using a Monte Carlo simulation method. Target attainment was also examined as a function of patient weight and continuous RRT effluent rate. RESULTS: Sixty-eight participants had data for analysis. Regardless of infusion duration, 6 g/d piperacillin was associated with ≤45% target attainment, whereas 12 g/d was associated with ≥95% target attainment. For 8 and 9 g/d, target attainment ranged between 68% and 85%. The probability of target attainment was lower at higher effluent rates and patient weights. For all doses, frequencies, patient weights, and continuous RRT effluent rates, extended infusion was associated with higher probability of target attainment compared with short infusion. CONCLUSIONS: Extended infusions of piperacillin-tazobactam are associated with greater probability of target attainment in patients receiving continuous RRT.

Although traumatic brain injury (TBI) can happen to anyone at any time, the wars in Iraq and Afghanistan have brought it renewed attention. Fortunately, most cases of TBI from the recent conflicts are mild TBI (mTBI). Still, many physical, psychological, and social problems are associated with mTBI. Among the difficulties encountered are oculomotor and vision problems, many of which can impede daily activities such as reading. Therefore, correct diagnosis and treatment of these mTBI-related vision problems is an important part of patient recovery. Numerous eye care providers in the Department of Veterans Affairs, in military settings, and in civilian practices specialize and are proficient in examining patients who have a history of TBI. However, many do not have this level of experience working with and treating patients with mTBI. Recognizing this, we used a modified Delphi method to derive expert opinions from a panel of 16 optometrists concerning visual examination of the patient with mTBI. This process resulted in a clinical tool containing 17 history questions and 7 examination procedures. This tool provides a set of clinical guidelines that can be used as desired by any eye care provider either as a screening tool or adjunct to a full eye examination when seeing a patient with a history of mTBI. The goal of this process was to provide optimal and uniform vision care for the patient with mTBI.
