Evaluation of contraction of the split‐thickness skin graft using three dermal matrices in the treatment of burn contractures: A randomised clinical trial

Burn injuries commonly result in serious sequelae (such as skin contractures) in surviving patients, for which no single optimal solution is known. The goal of this study was to compare the late contraction of autologous skin grafts with or without dermal matrices used in the treatment of patients with burn contractures. This parallel design prospective, randomised and controlled clinical trial included patients with burn contracture treated using autologous skin grafts and dermal matrix. Patients were randomly assigned to one of the four groups: Integra® matrix (n = 10), Pelnac® matrix (n = 10), Matriderm® matrix (n = 9) or a Control Group (n = 10, without dermal matrix, only skin graft). The boundaries of skin defect were marked and transferred to a flat sterile surface for area measurement. The current area of the skin grafts was measured during surgery and compared with those obtained at 1, 3, 6 and 12 months postoperatively. Twelve months after surgery, the Control Group presented lower rates of skin graft contraction than Integra® (p < 0.01), Matriderm® (p = 0.01) and Pelnac® (p < 0.01) groups. Pelnac® resulted in larger skin graft contraction than Matriderm® (p < 0.01) and Integra® (p = 0.02), while differences between Integra® and Matriderm® were not significant (p = 0.16). The comparison between intraoperative and 12 months after surgery showed that the worst mean rates of skin graft contraction were from the Pelnac® (51.79%) and Matriderm® (59.17%). In patients with burn contractures, the use of these three dermal matrices did not reduce or avoid the occurrence of late contraction of the skin graft, so their use for this purpose should be carefully evaluated.
Advance care planning in dementia care: Wants, beliefs, and insight

Background: Advance care planning gives patients and their family members the possibility to consider and make decisions regarding future care and medical procedures. Aim: To explore the view of people in the early stage of dementia on planning for future care. Research design: The study is a qualitative interview study with a semistructured interview guide. The data were analyzed according to the Qualitative Analysis Guide of Leuven. Participants and research context: Dementia nurses assisted in the recruiting of people with dementia for participation in the study. Study information was mailed to 95 people with early stage dementia. Ten people with dementia and eight caregiver spouses participated in the study. Ethical considerations: People with dementia belong to a vulnerable patient group, and care was taken in the areas of informed consent and accessible information. Findings: The views of people with dementia are characterized by a complex storyline involving tensions and movement within the themes of wants, beliefs, and levels of insight. Participants wanted to think about the future but also wanted to live in the here and now. Discussion: High demands are placed on the advance care planning process for people with dementia and their family caregivers. A dignity-enhancing approach in dementia care emphasizes the dignity of and respect for this vulnerable and care-dependent patient group. Conclusion: The process of advance care planning in dementia care needs to go beyond person-centered care to a relationship-centered process. The illness trajectory and the impact on autonomy need to be taken into consideration.
Long‐term outcomes in sinonasal squamous cell carcinoma arising from inverted papilloma: Systematic review

Long‐term survival and recurrence patterns of squamous cell carcinoma arising from inverted papilloma (IP‐SCC) have not been thoroughly investigated. Four electronic databases were searched and primary studies describing overall survival (OS), recurrence, and mean time to recurrence of patients with IP‐SCC were included for review. Our search yielded 662 studies. The 28 studies selected for inclusion identified 663 patients with IP‐SCC. In 596 patients with reported T classification, 439 (73.7%) were T3/T4 on presentation. Of the 650 participants with recurrence data (local, regional, and distant), 155 (23.8%) experienced a recurrence, with an aggregate mean time‐to‐recurrence of 24.3 months. In 565 patients with 5‐year OS rates, the aggregate 5‐year OS was 62%. Based on the literature to date, IP‐SCC is associated with a 5‐year OS rate of 62%. 23.8% of patients experienced recurrence at a mean time of 24.3 months, suggesting the need for long‐term surveillance.
How have media campaigns been used to promote and discourage healthy and unhealthy beverages in the United States? A systematic scoping review to inform future research to reduce sugary beverage health risks

Sugary beverage consumption is associated with many health risks. This study used a proof‐of‐concept media campaign typology to examine U.S. beverage campaigns that promoted healthy beverages and encouraged or discouraged sugary beverages. We used a three‐step systematic scoping review to identify, organize, analyze, and synthesize evidence. Step 1 used Preferred Reporting Items for Systematic Review and Meta‐Analysis Extension for Scoping Reviews (PRISMA‐ScR) guidelines to search four electronic databases and gray literature through 2021. Step 2 categorized relevant media campaigns using a media campaign typology. Step 3 examined campaign evaluation outcomes. We identified 280 campaigns organized into six campaign typology categories. The media landscape was dominated by corporate marketing campaigns for branded sugary beverages (65.8%; n = 184) followed by public awareness (9.6%; n = 27), public policy (8.2%; n = 23), social marketing (7.1%; n = 20), corporate social responsibility (5.7%; n = 16), and countermarketing (3.6%; n = 10) campaigns. Evaluations for 20 unique campaigns implemented over 30 years (1992–2021) across 14 states showed reduced sugary beverage or juice and increased water or low‐fat milk sales and intake. Positive short‐term cognitive and mid–term retail and behavioral changes were reported. There was limited evidence for long‐term policy, social norm, and population health outcomes. Future research is needed to use media campaigns in strategic communications to reduce sugary beverage health risks for Americans.
Graded peak cycle ergometer test for cognitively impaired patients with Parkinson’s disease: a pilot study

ABSTRACT Background Cognitive decline affects up to 50% of patients with Parkinson’s disease (PD) in the course of the disease and may be amenable to exercise interventions. To accurately set adequate training intensities, standardized exercise testing is required but such testing takes considerable time and effort. The aim of this pilot study was to investigate the feasibility of a graded peak cycle ergometer exercise test in cognitively impaired patients with Parkinson’s Disease (PD), and to define whether age-predicted maximal heart rate (HRmax) matched measured HRmax. Methods A convenience sample of seven patients with PD (Hoehn and Yahr: 2–4, and cognitive impairment (Montreal Cognitive Assessment (MoCA) ≤ 26) completed a graded peak cycle ergometer test to voluntary exhaustion. Borg Rating of Perceived Exertion was used to record the individual’s perception of exertion. Pre-defined age-predicted HRmax (calculated as 208-(0.7 × age) was compared with the measured HRmax using Bland-Altman plot and a two-one-sided test. Results All PD patients completed the graded exercise test between 8–12 minutes, showing therefore 100% compliance to the test protocol. No adverse events occurred. Predicted HRmax and measured HRmax did not differ. Conclusion We demonstrate feasibility of graded peak cycle ergometer testing in PD patients with cognitive impairment. The good correspondence of age-predicted HRmax equation with measured HRmax, in this small sample, may in the future provide clinicians with a tool to define training intensities in cognitively impaired PD, without cardiac disease. However, further research is needed to confirm these results.
Ebola virus persistence and disease recrudescence in the brains of antibody-treated nonhuman primate survivors

Effective therapeutics have been developed against acute Ebola virus disease (EVD) in both humans and experimentally infected nonhuman primates. However, the risk of viral persistence and associated disease recrudescence in survivors receiving these therapeutics remains unclear. In contrast to rhesus macaques that survived Ebola virus (EBOV) exposure in the absence of treatment, we discovered that EBOV, despite being cleared from all other organs, persisted in the brain ventricular system of rhesus macaque survivors that had received monoclonal antibody (mAb) treatment. In mAb-treated macaque survivors, EBOV persisted in macrophages infiltrating the brain ventricular system, including the choroid plexuses. This macrophage infiltration was accompanied by severe tissue damage, including ventriculitis, choroid plexitis, and meningoencephalitis. Specifically, choroid plexus endothelium-derived EBOV infection led to viral persistence in the macaque brain ventricular system. This resulted in apoptosis of ependymal cells, which constitute the blood–cerebrospinal fluid barrier of the choroid plexuses. Fatal brain-confined recrudescence of EBOV infection manifested as severe inflammation, local pathology, and widespread infection of the ventricular system and adjacent neuropil in some of the mAb-treated macaque survivors. This study highlights organ-specific EBOV persistence and fatal recrudescent disease in rhesus macaque survivors after therapeutic treatment and has implications for the long-term follow-up of human survivors of EVD. Description Ebola virus persists in the brain ventricular system of nonhuman primates treated with monoclonal antibodies. Ebola virus: Hiding in plain sight The host-pathogen determinants of Ebola virus (EBOV) persistence and disease recrudescence in immune-privileged organs, including any association with standard-of-care monoclonal antibody–based treatments, remain to be elucidated. In new work, Liu et al. report frequent EBOV persistence in the brain ventricular system of nonhuman primates that survived acute disease after monoclonal antibody–based treatment. Viral persistence was associated with lethal recrudescence of disease including severe inflammation in the brain. These findings have implications for long-term follow-up efforts to reduce the individual (disease relapse/recrudescence) and public health (reignition of outbreaks) consequences of viral persistence in survivors of EBOV infection.
Signatures of hybridization in Trypanosoma brucei

Genetic exchange among disease-causing micro-organisms can generate progeny that combine different pathogenic traits. Though sexual reproduction has been described in trypanosomes, its impact on the epidemiology of Human African Trypanosomiasis (HAT) remains controversial. However, human infective and non-human infective strains of Trypanosoma brucei circulate in the same transmission cycles in HAT endemic areas in subsaharan Africa, providing the opportunity for mating during the developmental cycle in the tsetse fly vector. Here we investigated inheritance among progeny from a laboratory cross of T. brucei and then applied these insights to genomic analysis of field-collected isolates to identify signatures of past genetic exchange. Genomes of two parental and four hybrid progeny clones with a range of DNA contents were assembled and analysed by k-mer and single nucleotide polymorphism (SNP) frequencies to determine heterozygosity and chromosomal inheritance. Variant surface glycoprotein (VSG) genes and kinetoplast (mitochondrial) DNA maxi- and minicircles were extracted from each genome to examine how each of these components was inherited in the hybrid progeny. The same bioinformatic approaches were applied to an additional 37 genomes representing the diversity of T. brucei in subsaharan Africa and T. evansi. SNP analysis provided evidence of crossover events affecting all 11 pairs of megabase chromosomes and demonstrated that polyploid hybrids were formed post-meiotically and not by fusion of the parental diploid cells. VSGs and kinetoplast DNA minicircles were inherited biparentally, with approximately equal numbers from each parent, whereas maxicircles were inherited uniparentally. Extrapolation of these findings to field isolates allowed us to distinguish clonal descent from hybridization by comparing maxicircle genotype to VSG and minicircle repertoires. Discordance between maxicircle genotype and VSG and minicircle repertoires indicated inter-lineage hybridization. Significantly, some of the hybridization events we identified involved human infective and non-human infective trypanosomes circulating in the same geographic areas.
Comparison of sex determination using three methods applied to the greater sciatic notch of os coxae in a Thai population: Dry bone morphology, 2-dimensional photograph morphometry, and deep learning artificial neural network

The os coxa is commonly used for sex and age estimation with a high degree of accuracy. Our study aimed to compare the accuracy among three methods, which include a deep learning approach to increase the accuracy of sex prediction. A total sample of 250 left os coxae from a Thai population was divided into a ‘training’ set of 200 samples and a ‘test’ set of 50 samples. The age of the samples ranged from 26 to 94 years. Three methods of sex determination were assessed in this experiment: a dry bone method, an image-based method and deep learning method. The intra- and inter-observer reliabilities were also assessed in the dry bone and photo methods. Our results showed that the accuracies were 80.65%, 90.3%, and 91.95% for the dry bone, image-based, and deep learning methods, respectively. The greater sciatic notch shape was wide and symmetrical in females while narrow and asymmetrical in males. The intra- and inter-observer agreements were moderate to almost perfect level (Kappa = 0.67−0.93, ICC = 0.74−0.94). Conclusion: The image-based and deep learning methods were efficient in sex determination. However, the deep learning technique performed the best among the three methods due to its high accuracy and rapid analysis. In this study, deep learning technology was found to be a viable option for remote consultations regarding sex determination in the Thai population.
Clinical manifestation and long‐term outcome of citrin deficiency: Report from a nationwide study in Japan

Citrin deficiency is an autosomal recessive disorder caused by mutations in the SLC25A13 gene. The disease can present with age‐dependent clinical manifestations: neonatal intrahepatic cholestasis by citrin deficiency (NICCD), failure to thrive, and dyslipidemia by citrin deficiency (FTTDCD), and adult‐onset type II citrullinemia (CTLN2). As a nationwide study to investigate the clinical manifestations, medical therapy, and long‐term outcome in Japanese patients with citrin deficiency, we collected clinical data of 222 patients diagnosed and/or treated at various different institutions between January 2000 and December 2019. In the entire cohort, 218 patients were alive while 4 patients (1 FTTDCD and 3 CTLN2) had died. All patients <20 years were alive. Patients with citrin deficiency had an increased risk for low weight and length at birth, and CTLN2 patients had an increased risk for growth impairment during adolescence. Liver transplantation has been performed in only 4 patients (1 NICCD, 3 CTLN2) with a good response thereafter. This study reports the diagnosis and clinical course in a large cohort of patients with citrin deficiency and suggests that early intervention including a low carbohydrate diet and MCT supplementation can be associated with improved clinical course and long‐term outcome.
Recent developments of neuroprotective agents for degenerative retinal disorders

Retinal degeneration is a debilitating ocular complication characterized by the progressive loss of photoreceptors and other retinal neurons, which are caused by a group of retinal diseases affecting various age groups, and increasingly prevalent in the elderly. Age-related macular degeneration, diabetic retinopathy and glaucoma are among the most common complex degenerative retinal disorders, posing significant public health problems worldwide largely due to the aging society and the lack of effective therapeutics. Whilst pathoetiologies vary, if left untreated, loss of retinal neurons can result in an acquired degeneration and ultimately severe visual impairment. Irrespective of underlined etiology, loss of neurons and supporting cells including retinal pigment epithelium, microvascular endothelium, and glia, converges as the common endpoint of retinal degeneration and therefore discovery or repurposing of therapies to protect retinal neurons directly or indirectly are under intensive investigation. This review overviews recent developments of potential neuroprotectants including neuropeptides, exosomes, mitochondrial-derived peptides, complement inhibitors, senolytics, autophagy enhancers and antioxidants either still experimentally or in clinical trials. Effective treatments that possess direct or indirect neuroprotective properties would significantly lift the burden of visual handicap.
Sexual Modesty in Sexual Expression and Experience: A Scoping Review, 2000 - 2021

ABSTRACT Sexual modesty is the social, cultural, interpersonal, and psychological systems – defined by the tenets of Script Theory – that regulate individuals’ sexual expression and experience at the social, legal, and interpersonal boundaries of acceptable/not-acceptable, private/public, and personal/social. Almost all aspects of sexual expression and experience are touched by the pervasive modesty standards for sexual communication, sexual display, sexual relations, and sexual behaviors. Sexual modesty influences an array of sexual and reproductive health outcomes. Many aspects of sexual modesty are enforced by legal as well as social, cultural, and religious proscriptions, including social shaming and ostracism as well as corporal and capital punishments. The purpose of this paper is to summarize a diverse literature related to sexual modesty from the years 2000 to 2021 in order to clarify its role in sexual health and sexual wellbeing and to identify directions for new research.
Early versus late response to daratumumab-based triplet therapies in patients with multiple myeloma: a pooled analysis of trials POLLUX, CASTOR and MAIA

Abstract In multiple myeloma (MM), it is unclear whether early and late responders to daratumumab have similar outcomes. We pooled individual-level data from phase 3 trials and divided them into early and late response groups based on median time to response. Altogether 670 and 213 patients achieved very good partial response (VGPR) or better and minimal residual disease (MRD) negativity, respectively. Among VGPR or better, there was no significant difference of modified progression-free survival (mPFS, hazard ratio [HR] 1.00, 95% confidence interval [CI] 0.69–1.44) or duration of response (DOR) (HR 1.02, 95%CI 0.68–1.53). Among relapsed/refractory MM (RRMM) achieving MRD negativity, late responders had significantly longer mPFS (p = 0.038) and DOR (p = 0.043). These results support that for patients who failed to achieve an early response to daratumumab, therapies should be continued with the goal of achieving ongoing and stepwise improvement of response.
Yeast Dxo1 is required for 25S rRNA maturation and acts as a transcriptome-wide distributive exonuclease

The Dxo1/Rai1/DXO family of decapping and exonuclease enzymes can catalyze the in vitro removal of chemically diverse 5′ ends from RNA. Specifically, these enzymes act poorly on RNAs with a canonical 7mGpppN cap, but instead prefer RNAs with a triphosphate, monophosphate, hydroxyl, or nonconventional cap. In each case, these enzymes generate an RNA with a 5′ monophosphate, which is then thought to be further degraded by Rat1/Xrn1 5′ exoribonucleases. For most Dxo1/Rai1/DXO family members, it is not known which of these activities is most important in vivo. Here we describe the in vivo function of the poorly characterized cytoplasmic family member, yeast Dxo1. Using RNA-seq of 5′ monophosphate ends, we show that Dxo1 can act as a distributive exonuclease, removing a few nucleotides from endonuclease or decapping products. We also show that Dxo1 is required for the final 5′ end processing of 25S rRNA, and that this is the primary role of Dxo1. While Dxo1/Rai1/DXO members were expected to act upstream of Rat1/Xrn1, this order is reversed in 25S rRNA processing, with Dxo1 acting downstream from Rat1. Such a hand-off from a processive to a distributive exonuclease may be a general phenomenon in the precise maturation of RNA ends.
Nonconsensual Distribution of Sexually Explicit Images Within a Context of Coercive Control: Frequency, Characteristics, and Associations with Other Forms of Victimization

The present study examined the frequency and characteristics of nonconsensual distribution of sexually explicit images (NCD) among undergraduates (n = 496) and its co-occurrence with other forms of interpersonal violence (e.g., physical, sexual, and psychological abuse). Overall, 17.34% of participants reported NCD victimization; most were women (90.70%). Women who reported NCD from current/former partners (71.79%), compared to non-romantic acquaintances, reported more additional interpersonal violence from the same perpetrator and marginally higher threats of NCD, but were no more likely to receive NCD demands. NCD appears to occur within a pattern of elevated violence; prevention and intervention efforts are needed.
Loss of a Pyridoxal-Phosphate Phosphatase Rescues Arabidopsis Lacking an Endoplasmic Reticulum ATP Carrier.

The endoplasmic reticulum (ER)-located ATP/ADP-antiporter (ER-ANT1) occurs specifically in vascular plants. Structurally different transporters mediate energy provision to the ER, but the cellular function of ER-ANT1 is still unknown. Arabidopsis (Arabidopsis thaliana) mutants lacking ER-ANT1 (er-ant1 plants) exhibit a photorespiratory phenotype accompanied by high glycine levels and stunted growth, pointing to an inhibition of glycine decarboxylase. To reveal whether it is possible to suppress this marked phenotype, we exploited the power of a forward genetic screen. Absence of a so far uncharacterized member of the HaloAcid Dehalogenase (HAD)-like hydrolase family strongly suppressed the dwarf phenotype of er-ant1 plants. Localization studies suggested that the corresponding protein locates to chloroplasts, and activity assays showed that the enzyme dephosphorylates, with high substrate affinity, the B6 vitamer pyridoxal 5'-phosphate (PLP). Additional physiological experiments identified imbalances in vitamin B6 homeostasis in er-ant1 mutants. Our data suggest that impaired chloroplast metabolism, but not decreased glycine decarboxylase (GDC) activity, causes the er-ant1 mutant dwarf phenotype. We present a hypothesis, setting transport of PLP by ER-ANT1 and chloroplastic PLP dephosphorylation in the cellular context. With the identification of this HAD-type PLP phosphatase, we also provide insight into B6 vitamer homeostasis.
