Increasing healthcare costs, limited healthcare resources, an aging population, and lifestyle-related diseases make wound management a growing clinical, social, and economic burden. This case series investigated the use of a novel, biocompatible, polymer-based transforming powder dressing (TPD) that transforms in situ to a shape-retentive wound matrix upon hydration for treating wounds of various etiologies.In this institutional review board-approved single-center retrospective case series, the researchers evaluated various acute and chronic wounds treated with TPD over a period of 2 years. Wounds were followed from the first TPD application up to 1 month after the last TPD application or until the wound healed or the patient was lost to follow-up, whichever came first. The researchers evaluated wound etiology, location, number of applications, change in wound surface area, and comorbidities.The researchers identified 50 patients who were treated with TPD and had at least one follow-up visit during the retrospective study period. The majority of wounds treated with TPD were venous leg ulcers (n = 27) followed by traumatic wounds (n = 11) and skin tears (n = 7). Normal rates of wound healing (>10% per week) were observed in the majority of patients (36/50, 72%) over their duration of treatment. Complete healing during the study period was observed in 43% of venous leg ulcers, 55% of traumatic wounds, 71% of skin tears, and 80% of other wound types. No adverse effects of TPD administration were observed. Treatment with TPD resulted in significant reductions in wound area of nearly all wounds, regardless of etiology.

Imaging plays a crucial role in the immediate evaluation of the trauma patient, particularly using multi-detector computed tomography (CT), and especially in moderately to severely injured trauma patients. There are specific areas of relative consensus, while other aspects of whole-body computed tomography (WB-CT) use remain controversial and are subject to opinion/debate based on the current literature. Even a few hours of a delayed diagnosis may result in a detrimental outcome for the patient. One must utilize all the tools available to enhance the interpretation of images. It is also important to recognize imaging pitfalls and artifacts to avoid unnecessary intervention.

OBJECTIVE: Recent studies have reported associations between severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection during pregnancy and adverse perinatal outcomes but the extent to which these associations vary by race/ethnicity remains uncertain. Therefore, we examined how the association between prenatal SARS-CoV-2 infection and adverse perinatal outcomes may be modified by race/ethnicity. STUDY DESIGN/METHODS: A retrospective cohort study was performed using data on 67,986 pregnant women extracted from the Kaiser Permanente Southern California electronic health records between April 6, 2020, and December 31, 2021. Upon admission to labor and delivery, all women were routinely tested for coronavirus disease 2019 (COVID-19) using real-time reverse-transcriptase polymerase chain reaction test. Adjusted odds ratios (aORs) were used to estimate associations. RESULTS: During the study period, COVID-19 was diagnosed in 4,960 (7%) of singleton pregnancies, with the highest rates observed among Hispanics (9.4%) and non-Hispanic Blacks (6.2%). Compared with non-Hispanic Whites, Hispanics (aOR: 1.12, 95% CI: 1.03, 1.21) with SARS-CoV-2 infection had the highest odds of a pregnancy associated with nonreassuring fetal heart rate tracing. Neonates of all races/ethnicities, except for non-Hispanic Blacks, showed significantly increased odds of SARS-CoV-2 infection, with the highest risk observed among Asians/Pacific Islanders (aOR: 10.88, 95% CI: 1.33, 89.04). Non-Hispanic White mothers who tested positive were admitted to intensive care unit (ICU) at a higher rate at delivery and within 7 days of delivery (aOR: 34.77, 95% CI: 11.3, 107.04; aOR: 26.48, 95% CI: 9.55, 73.46, respectively). Hispanics were also at a significantly higher odds of admission to ICU (aOR: 4.62, 95% CI: 2.69, 7.94; aOR: 4.42, 95% CI: 2.58, 7.56, respectively). Non-Hispanic Black, Hispanic, and Asian/Pacific Islander mothers who tested positive for SARS-CoV-2 prenatally, were at increased risk for preeclampsia/eclampsia, and preterm birth as compared to non-Hispanic White mothers. CONCLUSION/CONCLUSIONS: The findings highlight racial/ethnic disparities in the association between SARS-CoV-2 infection and adverse perinatal outcomes. The risk of neonatal SARS-CoV-2 infection was highest for Asian/Pacific Islanders. We also observed a remarkably high risk of ICU admission for non-Hispanic White mothers infected with SARS-CoV-2. KEY POINTS/CONCLUSIONS:· Race/ethnicity influences perinatal outcomes in pregnancies impacted by SARS-CoV-2.. · The risk of neonatal SARS-CoV-2 infection was highest for Asian/Pacific Islanders.. · White mothers had a notably high risk of ICU admission at delivery following SARS-CoV-2 infection..

Dementia and Alzheimer's disease are common occurrences in the population, affecting many patients. Recent research and studies have found a link between oral biofilm and the initiation of these conditions or the worsening of their presentation. Periodontal disease and the associated oral biofilm with its bacteria are often not considered by the medical community when treating these or their patients. Coordination of therapy with a dentist can improve the patient's oral health. Decreasing bacteria in the oral biofilm allows the physician and dentist to provide coordinated total healthcare. Emphasis and education of the patient on the importance of maintaining good oral homecare and routine dental recall prophylaxis appointments to improve their systemic health and limit the progression and worsening of mental health conditions. This article discusses the connection between oral biofilm and systemic health, specifically Alzheimer's disease, and how to improve those conditions through oral healthcare.

AIMS/OBJECTIVE:Anal cancer, despite its rarity, is a matter of serious concern in the United States, with an uptrend in recent years and marked racial disparities in mortality rates. The aim of this work was to investigate anal cancer mortality trends and sex race disparities in the United States from 1999 to 2020. METHOD/METHODS:This is a retrospective study using data from the CDC WONDER database (1999-2020). We investigated deaths attributed to anal cancer, identified by the ICD-10 code C21.1, and excluded individuals aged 14 years and under. The Mann-Kendall trend test was used to investigate temporal trends and a t-test was used to compare continuous variables. RESULTS:Both male and female age-adjusted mortality attributed to anal cancer increased significantly during the study period across all subgroups, including race (Black and White), US Census region (Northeast, Midwest, South and West) and age (15-64 and ≥65 years) (p < 0.001 for all comparisons). For each subgroup, women demonstrated significantly higher rates of mortality than men, except in the Black population, where Black men had higher rates than Black women (0.40 vs. 0.29, p < 0.001). Additionally, Black men had significantly higher mean mortality rates than White men (0.40 vs. 0.27, p < 0.001). The highest rates of anal cancer mortality were among geriatric individuals, especially women aged ≥65 years, at 1.18 per 100 000. CONCLUSION/CONCLUSIONS:The rise in anal cancer mortality and racial and sex disparities present a significant challenge for healthcare providers and policy makers. Further studies are required to devise evidence-based strategies to effectively tackle this challenge.

BACKGROUND:Peripheral nerve stimulation (PNS) has been used for over 50 years to treat chronic pain by delivering electrical pulses through small electrodes placed near targeted peripheral nerves those outside the brain and spinal cord. Early PNS systems often required invasive neurosurgical procedures. However, since 2015, the Food and Drug Administration (FDA) approved percutaneously implanted PNS leads and neurostimulators  offering a much less invasive, non-opioid option for managing recalcitrant chronic pain. The following FDA-cleared PNS systems are commercially available in the United States for the management of chronic, intractable pain:•    Freedom® Peripheral Nerve Stimulator (PNS) System (Curonix LLC, 2017) •    StimRouter® Neuromodulation System (Bioness, now Bioventus, 2015)•    SPRINT® PNS System (SPR® Therapeutics, Inc., 2016) •    Nalu™ Neurostimulation System (Nalu Medical Inc., 2019)•    ReActiv8® Implantable Neurostimulation System (Mainstay Medical Limited, 2020) The American Society of Interventional Pain Physicians (ASIPP) has published evidence-based consensus guidelines for the application of PNS systems in managing chronic pain. OBJECTIVE:The guidelines aim to provide evidence-based recommendations for the utilization of peripheral nerve stimulation (PNS) in the management of moderate to severe chronic pain. These guidelines exclude field stimulation, or sacral nerve stimulation. METHODS:A multidisciplinary panel of experts in various medical and pharmaceutical fields, convened by ASIPP, reviewed the evidence, considered patient perspectives, and formulated recommendations for implantable peripheral nerve stimulation in chronic pain management. The methodology included developing key questions with evidence-based statements and recommendations. The grading of evidence and recommendations followed a modified approach described by ASIPP, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method, and the Agency for Healthcare Research and Quality (AHRQ) strength of recommendations methods. The evidence review includes existing guidelines, systematic reviews, comprehensive reviews, randomized controlled trials (RCTs), and observational studies on the effectiveness and safety of implantable peripheral nerve stimulation in managing chronic pain. The quality of published studies was assessed using appropriate instruments for systematic reviews, RCTs, and observational studies.In the development of consensus statements and guidelines, we used a modified Delphi technique, which has been described to minimize bias related to group interactions. Panelists without a primary conflict of interest voted to approve specific guideline statements. Each panelist could suggest edits to the guideline statement wording and could suggest additional qualifying remarks or comments as to the implementation of the guideline in clinical practice to achieve consensus and for inclusion in the final guidelines, each guideline statement required at least 80% agreement among eligible panel members without primary conflict of interest. RESULTS:A total of 31 authors participated in the development of these guidelines. Of these, 23 participated in the voting process. A total of 8 recommendations were developed. Overall, 100% acceptance was obtained for 8 of 8 items. Thus, with appropriate literature review, consensus-based statements were developed for implantable peripheral nerve stimulation in chronic pain management. In preparation of these guidelines, evidence synthesis included 7 systematic reviews, 8 RCTs, and 9 observational studies covering all PNS treatments. The evidence was developed using GRADE criteria or certainty of evidence, and qualitative synthesis based on the best available evidence. The evidence level and recommendations are as follows: For implantable peripheral nerve stimulation systems following a trial or selective lumbar medial branch stimulation without a trial, the evidence is Level III or fair with moderate certainty.  Evidence Level: Fair; Strength of Recommendation: ModerateFor temporary peripheral nerve stimulation for 60 days, the evidence is Level III or fair, with moderate certainty. EVIDENCE LEVEL/METHODS:Fair; Strength of Recommendation: ModerateBased on the available evidence, it is our recommendation to expand the existing PNS related local coverage determination (LCD) to include craniofacial pain, phantom limb pain, and nociceptive pain in the lower back as present evidence shows Level III or fair with moderate certainty. LIMITATIONS/CONCLUSIONS:The primary limitation of these guidelines is the paucity of the available literature. CONCLUSION/CONCLUSIONS:These evidence-based guidelines support the use of implantable peripheral nerve stimulation leads and neurostimulators in patients with moderate to severe chronic pain refractory to two or more conservative treatments. These guidelines aim to optimize patient outcomes and promote health equity through the integration of PNS technology in clinical practice.

BACKGROUND:New anticancer therapies have improved patient outcomes but associated dermatologic adverse events (AEs) may cause morbidity and treatment discontinuation. A comprehensive estimation of associations between cancer drugs and skin AEs is lacking. METHODS:This study utilized the Food and Drug Administartion (FDA)'s Adverse Event Reporting System database (January 2013-September 2022), with 3,399,830 reports involving 3084 drugs and 16,348 AEs. A nearest neighbor matching model was employed to select 10 controls for each case report, utilizing the cosine similarity of demographic and AE severity factors to minimize false positives/negatives. RESULTS:There were 10,698 unique anticancer drugs (n = 212) to skin AE (n = 873) pairs, of which 676 had significant reporting odds ratios (ROR) > 1, comprising 113 drugs and 144 AEs. The minimum ROR was 1.25, and 50% of associations displayed a ROR >10. The most common were rash (51 agents) and dry skin (28 drugs). Methotrexate induced the most distinct AEs (34), then mechlorethamine (33), and vemurafenib (24). Targeted therapies accounted for 49% of pairs, cytotoxic chemotherapies for 35.9%, and immunotherapies for 11%. CONCLUSIONS:A total of 113 anticancer drugs were identified as significantly associated with skin AEs, most frequently rash and dry skin. Data are likely under-reported but enable quick postmarketing identification of skin toxicity signals.

To further explore the role of different antipsychotic treatments for cardio-cerebrovascular mortality, we performed several subgroup, sensitivity and meta-regression analyses based on a large previous meta-analysis focusing on cohort studies assessing mortality relative risk (RR) for cardio-cerebrovascular disorders in people with schizophrenia, comparing antipsychotic treatment versus no antipsychotic. Quality assessment through the Newcastle-Ottawa Scale (NOS) and publication bias was measured. We meta-analyzed 53 different studies (schizophrenia patients: n = 2,513,359; controls: n = 360,504,484) to highlight the differential effects of antipsychotic treatment regimens on cardio-cerebrovascular-related mortality in incident and prevalent samples of patients with schizophrenia. We found first generation antipsychotics (FGA) to be associated with higher mortality in incident samples of schizophrenia (oral FGA [RR=2.20, 95 %CI=1.29-3.77, k = 1] and any FGA [RR=1.70, 95 %CI=1.20-2.41, k = 1]). Conversely, second generation antipsychotics (SGAs) and clozapine were associated with reduced cardio-cerebrovascular-related mortality, in prevalent samples of schizophrenia. Subgroup analyses with NOS score ≥7 (higher quality) demonstrated a significantly increased cardio-cerebrovascular disorder-related mortality, among those exposed to FGAs vs SGAs. Meta-regression analyses demonstrated a larger association between antipsychotics and decreased risk of mortality with longer follow-up, recent study year, and higher number of adjustment variables. Overall, this subanalysis of a systematic review contributes to the evolving understanding of the complex role of antipsychotic treatment for cardio-cerebrovascular mortality in schizophrenia, paving the way for more targeted interventions and improved patient outcomes.

BACKGROUND:Because of advances in medical treatment of heart failure, patients are living longer than in previous eras and may approach the need for advanced therapies, including heart transplantation, at older ages. This study assesses practices surrounding heart transplant in older adults (> 70 years) and examines short- and medium-term outcomes. METHODS AND RESULTS/RESULTS:This study is a retrospective analysis using the United Network for Organ Sharing (UNOS) database from 2010 to 2021. The absolute number of older adults being transplanted is increasing. Older adults were more likely to have had a prior malignancy or ischemic cardiomyopathy and less likely to be on extra-corporeal membrane oxygenation or have a high UNOS status prior to transplant. Mortality at 1-year was higher for older adults (27.8% vs. 23.4%), but at 5 years there was no significant difference (22.3% vs. 19.4%.). Older adults were more likely to die of malignancy or infection. Adults under 70 were more likely to die of cardiovascular causes or graft failure. There was less rejection in older adults. Mortality has not changed for older adults transplanted before versus after the 2018 UNOS allocation change. CONCLUSIONS:Carefully selected older adults may be considered for heart transplantation, given similar intermediate-term mortality.
