This article explores the lessons that might be learned from port State con-trol (PSC) inspections for flag States, examining the scholarly literature on vessel risk targeting. It begins by identifying the major classification socie-ties (and recognized organizations or ROs) before discussing the obligations and responsibilities of governments in achieving a global 'safer ships and cleaner seas' objective. It then presents a framework for thinking about the relationship between owner/operators, ship classification societies, flag State authorities and PSC parties in order to improve safety, discussing where gaps remain in the execution of the objective. The author draws con-clusions about where the future focus by flag States might achieve addi-tional improvements in their oversight of classification societies when they act as ROs, carrying out ship survey and certification functions on behalf of flag States. Identified challenges include improving the quality of data used in vessel risk targeting, expanding the transparency of that data for RO oversight, and focusing efforts on those flag States and ROs who do not meet their obligations.

BACKGROUND: Many cancer risk factors are correlated with one another, and the presence of 1 risk factor may be a marker for other unhealthy behaviors. In this article, we focus on smokeless tobacco (ST), a known risk factor for oral leukoplakia and oral cancer, and the cancer risk factors associated with its use. METHODS: We analyzed cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) I and the 1982-1984 NHANES I Epidemiologic Follow-up Study. Risk factor information was available on individuals 25-74 years of age, most of whom would be middle age or elderly today. RESULTS: Older subjects, Black males, and those living in the Southern Unite States had the highest prevalence of ST use. ST use was associated with current smoking (odds ratio [OR], 1.3; 95% confidence interval [CI], 1.1-1.5), former smoking (OR, 1.6; 95% CI, 1.4-2.0), low fruit and vegetable intake, low SES, increased alcohol consumption (among nonsmoking ST users), and increased body mass index, all of which elevate cancer risk. CONCLUSION. Physicians and dentists should ask their patients about current or former ST use. Identification of ST users should prompt the physician or dentist to inquire about other chronic disease risk factors that the patient may have and to educate the ST using patient about ways to reduce their risk of cancer.

Health education programs developed in academic medical centers are not optimally disseminated to community clinical settings. Strategies are needed to translate the findings of research on health education programs into programs useful in a wide range of health care settings. Focus group techniques were used to provide data for revising a successful university-based asthma self-management program to make it more practical for use by community physicians. Physicians representing a variety of specialties attended the sessions and provided feedback on the utility of various components of the original program. The discussions revealed that many physicians felt they did not have the time or resources to conduct the original program and identified elements viewed as impractical. This physician input contributed significantly to the development of a revised program with a briefer, less costly intervention. The revised program was later evaluated by focus group participants. Eighty-eight percent of those who evaluated the revised program agreed they would be able and willing to use the program in their own practices. As a formative evaluation tool, the focus group technique made available useful information that would have been difficult to obtain through evaluation forms alone. [ABSTRACT FROM AUTHOR]

Importance: Recent articles have highlighted the existence of pelvic floor myofascial dysfunction in women presenting with pelvic floor disorders., Objective: The aim of the study was to evaluate whether younger age is associated with pelvic floor muscle dysfunction in women with lower urinary tract symptoms, including urinary urgency, frequency, nocturia, and urinary incontinence., Study Design: This retrospective cohort study included women seeking an initial outpatient urogynecology evaluation for urinary symptoms from 8/2018 to 2/2022. The primary outcome was the presence of pelvic floor muscle dysfunction, defined as a diagnosis of levator myalgia/spasm. Multivariable logistic regression was used to evaluate the association., Results: Four hundred twenty-one women with lower urinary tract symptoms were included, and 115 (27.3%) were diagnosed with pelvic floor muscle dysfunction. Women with pelvic floor dysfunction were 13 years younger, less likely to report any incontinence (60% vs 71.9%, P = 0.026) and urgency incontinence (8.7% vs 17.3%, P = 0.04). There was no difference in reported urgency, frequency, or nocturia. Women with pelvic floor dysfunction were more likely to report dysuria (19.1% vs 9.5%, P = 0.012), dyspareunia (39% vs 7.5%, P < 0.001), vulvodynia (11.3% vs 2.3%, P < 0.001), and pelvic pain (25.2% vs 7.2%, P < 0.001). The odds of pelvic floor muscle dysfunction in women <40 years old was 2.34 times greater than women ≥40 years old, after adjusting for other factors (adjusted odds ratio 2.341, 95% confidence interval [1.102, 4.972])., Conclusions: Younger women with lower urinary tract symptoms were significantly more likely to have pelvic floor muscle dysfunction compared to older women with similar symptoms, even after controlling for other associated characteristics., Competing Interests: The authors have declared they have no conflicts of interest., (Copyright © 2024 American Urogynecologic Society.

The Southern Ocean ecosystem has undergone extensive changes in the past two centuries driven by industrial sealing and whaling, climate change and commercial fishing. However, following the end of commercial whaling, some populations of whales in this region are recovering. Baleen whales are reliant on Antarctic krill, which is also the largest Southern Ocean fishery. Since 1993, krill catch has increased fourfold, buoyed by nutritional supplement and aquaculture industries. In this Perspective, we approximate baleen whale consumption of Antarctic krill before and after whaling to examine if the ecosystem can support both humans and whales as krill predators. Our back-of-the-envelope calculations suggest that current krill biomass cannot support both an expanding krill fishery and the recovery of whale populations to pre-whaling sizes, highlighting an emerging human-wildlife conflict. We then provide recommendations for enhancing sustainability in this region by reducing encounters with whales and bolstering the krill population., (© 2024. The Author(s).)

Fluoride-ion batteries have several potential advantages over lithium-ion batteries. Materials development is still needed, however, to realize electrolytes with sufficiently high anion conductivity and compatibility with anode and cathode layers. Fluoride compounds are difficult to synthesize directly as single crystals but can be realized from oxide film precursors via topotactic chemistry techniques. Here, we create crystalline alkaline earth bismuth fluoride films BaBiF 5 and SrBiF 5 through oxide molecular beam epitaxy and topotactic fluorination. We characterize their ionic conductivities and demonstrate their potential as electrolytes. Finally, we realize epitaxial synthesis of BaBiF 5 on BaF 2 substrates, providing a route to thin film fluoride-ion battery devices., Competing Interests: The authors declare no competing financial interest., (© 2024 The Authors.

Biodiversity is critical for maintaining ecosystem function but is threatened by increasing anthropogenic pressures. In the Southern Ocean, a highly biologically productive region containing many endemic species, proactive management is urgently needed to mitigate increasing pressures from fishing, climate change, and tourism. Site-based conservation is one important tool for managing the negative impacts of human activities on ecosystems. The Key Biodiversity Area (KBA) Standard is a standardized framework used to define sites vital for the persistence of global biodiversity based on criteria and quantitative thresholds. We used tracking data from 14 species of Antarctic and subantarctic seabirds and pinnipeds from the publicly available Retrospective Analysis of Antarctic Tracking Data (RAATD) data set to define KBAs for a diverse suite of marine predators. We used track2kba, an R package that supports identification of KBAs from telemetry data through identification of highly used habitat areas and estimates of local abundance within sites. We compared abundance estimates at each site with thresholds for KBA criteria A1, B1, and D1 (related to globally threatened species, individual geographically restricted species, and demographic aggregations, respectively). We identified 30 potential KBAs for 13 species distributed throughout the Southern Ocean that were vital for each individual species, population, and life-history stage for which they were determined. These areas were identified as highly used by these populations based on observational data and complement the ongoing habitat modeling and bioregionalization work that has been used to prioritize conservation areas in this region. Although further work is needed to identify potential KBAs based on additional current and future data sets, we highlight the benefits of utilizing KBAs as part of a holistic approach to marine conservation, given their significant value as a global conservation tool., (© 2024 The Author(s).

The Hildenbrandiales, a typically saxicolous red algal order, is an early diverging florideophycean group with global significance in marine and freshwater ecosystems across diverse temperature zones. To comprehensively elucidate the diversity, phylogeny, biogeography, and evolution of this order, we conducted a thorough re-examination employing molecular data derived from nearly 700 specimens. Employing a species delimitation method, we identified Evolutionary Species Units (ESUs) within the Hildenbrandiales aiming to enhance our understanding of species diversity and generate the first time-calibrated tree and ancestral area reconstruction for this order. Mitochondrial cox1 and chloroplast rbcL markers were used to infer species boundaries, and subsequent phylogenetic reconstructions involved concatenated sequences of cox1, rbcL, and 18S rDNA. Time calibration of the resulting phylogenetic tree used a fossil record from a Triassic purportedly freshwater Hildenbrandia species and three secondary time points from the literature. Our species delimitation analysis revealed an astounding 97 distinct ESUs, quintupling the known diversity within this order. Our time-calibration analysis placed the origin of Hildenbrandiales (crown age) in the Ediacaran period, with freshwater species emerging as a monophyletic group during the later Permian to early Triassic. Phylogenetic reconstructions identified seven major clades, experiencing early diversification during the Silurian to Carboniferous period. Two major evolutionary events-colonization of freshwater habitats and obligate systemic symbiosis with a marine fungus-marked this order, leading to significant morphological alterations without a commensurate increase in species diversification. Despite the remarkable newly discovered diversity, the extant taxon diversity appears relatively constrained when viewed against an evolutionary timeline spanning over 800 million years. This limitation may stem from restricted geographic sampling or the prevalence of asexual reproduction. However, species richness estimation and rarefaction analyses suggest a substantially larger diversity yet to be uncovered-potentially four times greater. These findings drastically reshape our understanding of the deeply diverging florideophycean order Hildenbrandiales species diversity, and contribute valuable insights into this order's evolutionary history and ecological adaptations. Supported by phylogenetic, ecological and morphological evidence, we established the genus Riverina gen. nov. to accommodate freshwater species of Hildenbrandiales, which form a monophyletic clade in our analyses. This marks the first step toward refining the taxonomy of the Hildenbrandiales, an order demanding thorough revisions, notably with the creation of several genera to address the polyphyletic status of Hildenbrandia. However, the limited diagnostic features pose a challenge, necessitating a fresh approach to defining genera. A potential solution lies in embracing a molecular systematic perspective, which can offer precise delineations of taxonomic boundaries., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Oxide heterostructures exhibit a vast variety of unique physical properties. Examples are unconventional superconductivity in layered nickelates and topological polar order in (PbTiO 3 ) n /(SrTiO 3 ) n superlattices. Although it is clear that variations in oxygen content are crucial for the electronic correlation phenomena in oxides, it remains a major challenge to quantify their impact. Here, we measure the chemical composition in multiferroic (LuFeO 3 ) 9 /(LuFe 2 O 4 ) 1 superlattices, mapping correlations between the distribution of oxygen vacancies and the electric and magnetic properties. Using atom probe tomography, we observe oxygen vacancies arranging in a layered three-dimensional structure with a local density on the order of 10 14  cm -2 , congruent with the formula-unit-thick ferrimagnetic LuFe 2 O 4 layers. The vacancy order is promoted by the locally reduced formation energy and plays a key role in stabilizing the ferroelectric domains and ferrimagnetism in the LuFeO 3 and LuFe 2 O 4 layers, respectively. The results demonstrate pronounced interactions between oxygen vacancies and the multiferroic order in this system and establish an approach for quantifying the oxygen defects with atomic-scale precision in 3D, giving new opportunities for deterministic defect-enabled property control in oxide heterostructures., (© 2024.

Background and Aims: Changes in kelp abundances on regional scales have been highly variable over the past half-century owing to strong effects of local and regional drivers. Here, we assess patterns and dominant environmental variables causing spatial and interspecific variability in kelp persistence and resilience to change in Nova Scotia over the past 40 years., Methods: We conducted a survey of macrophyte abundance at 251 sites spanning the Atlantic coast of Nova Scotia from 2019 to 2022. We use this dataset to describe spatial variability in kelp species abundances, compare species occurrences to surveys conducted in 1982 and assess changes in kelp abundance over the past 22 years. We then relate spatial and temporal patterns in abundance and resilience to environmental metrics., Key Results: Our results show losses of sea urchins and the cold-tolerant kelp species Alaria esculenta, Saccorhiza dermatodea and Agarum clathratum in Nova Scotia since 1982 in favour of the more warm-tolerant kelps Saccharina latissima and Laminaria digitata. Kelp abundances have increased slightly since 2000, and Saccharina latissima and L. digitata are widely abundant in the region today. The highest kelp cover occurs on wave-exposed shores and at sites where temperatures have remained below thresholds for growth (21 °C) and mortality (23 °C). Moreover, kelp has recovered from turf dominance following losses at some sites during a warm period from 2010 to 2012., Conclusions: Our results indicate that dramatic changes in kelp community composition and a loss of sea urchin herbivory as a dominant driver of change in the system have occurred in Nova Scotia over the past 40 years. However, a broad-scale shift to turf-dominance has not occurred, as predicted, and our results suggest that resilience and persistence are still a feature of kelp forests in the region despite rapid warming over the past several decades., (© The Author(s) 2023.

Importance: Endometrial cancer and precancer are common gynecologic problems for many women. A majority of these patients require surgery as the mainstay of treatment. Many of these patients often have concurrent pelvic floor disorders. Despite the prevalence and shared risk, fewer than 3% of women undergo concomitant surgery for PFDs at the time of surgery for endometrial cancer or endometrial intraepithelial neoplasia/hyperplasia., Objective: This study aimed to evaluate postoperative morbidity of concomitant pelvic organ prolapse (POP) and/or urinary incontinence (UI) procedures at the time of hysterectomy for endometrial cancer (EC) or endometrial intraepithelial neoplasia/endometrial hyperplasia (EIN/EH)., Methods: This retrospective analysis of women undergoing hysterectomy for EC or EIN/EH between 2017 and 2022 used the American College of Surgeons National Surgical Quality Improvement Program database. The primary outcome was any major complication within 30 days of surgery. Comparisons were made between 2 cohorts: hysterectomy with concomitant pelvic organ prolapse/urinary incontinence procedures (POPUI) versus hysterectomy without concomitant POP or UI procedures (HYSTAlone). A subgroup analysis was performed in patients with EC. A propensity score matching cohort was also created., Results: A total of 23,144 patients underwent hysterectomy for EC or EIN/EH: 1.9% (n = 432) had POP and/or UI procedures. Patients with POPUI were older, were predominantly White, had higher parity, and had lower body mass index with lower American Society of Anesthesiologists class. Patients with POPUI were less likely to have EC (65.7% vs 78.3%, P < 0.0001) and more likely to have their hysterectomy performed by a general obstetrician- gynecologists or urogynecologists. Major complications were low and not significantly different between POPUI and HYSTAlone (3.7% vs 3.6%, P = 0.094). A subgroup analysis of EC alone found that the HYSTAlone subset did not have more advanced cancers, yet the surgeon was more likely a gynecologic oncologist (87.1% vs 68.0%, P < 0.0001). There were no statistically significant differences between the 2 cohorts for the primary and secondary outcomes using propensity score matching analysis., Conclusions: Concomitant prolapse and/or incontinence procedures were uncommon and did not increase the rate of 30-day major complications for women undergoing hysterectomy for EC/EH., (Copyright © 2024 American Urogynecologic Society.

Pelvic floor disorders are a group of common conditions affecting women of all racial and ethnic groups. These disorders are undertreated in all women, but this is especially magnified in Black people who have been historically marginalized in the United States. This article seeks to highlight the prevalence of pelvic floor disorders in Black women, evaluate the clinical care they receive, examine barriers they face to equitable care, and present a strategic agenda to prioritize the care of Black women with pelvic floor disorders., Competing Interests: Disclosures Dr M.F.

Antarctic coastal waters are home to several established or proposed Marine Protected Areas (MPAs) supporting exceptional biodiversity. Despite being threatened by anthropogenic climate change, uncertainties remain surrounding the future ocean acidification (OA) of these waters. Here we present 21st-century projections of OA in Antarctic MPAs under four emission scenarios using a high-resolution ocean-sea ice-biogeochemistry model with realistic ice-shelf geometry. By 2100, we project pH declines of up to 0.36 (total scale) for the top 200 m. Vigorous vertical mixing of anthropogenic carbon produces severe OA throughout the water column in coastal waters of proposed and existing MPAs. Consequently, end-of-century aragonite undersaturation is ubiquitous under the three highest emission scenarios. Given the cumulative threat to marine ecosystems by environmental change and activities such as fishing, our findings call for strong emission-mitigation efforts and further management strategies to reduce pressures on ecosystems, such as the continuation and expansion of Antarctic MPAs., (© 2024.

Background: Female sexual dysfunction (FSD) is a common problem in the United States; however, only 14% to 40% of women are screened by their health care clinicians. There are few data on how differences in clinician type affects screening rates., Aim: This study aimed to assess differences in FSD screening rates among gynecology clinician types, identify factors associated with screening, and compare screening rates of FSD against conditions with established screening recommendations., Methods: Data were collected by retrospective chart review of annual visits at an urban tertiary care center. Screening rates for FSD, depression, cervical cancer, and breast cancer were calculated and compared. Multivariable logistic regression modeling was utilized to assess the correlation between various patient characteristics and FSD screening rates., Outcomes: Study outcome measures included percentages of women who were screened for FSD, depression, cervical cancer, and breast cancer., Results: FSD screening rate was significantly higher among resident-level clinicians vs nonresident clinicians (59% vs 31%; P < .001). When the nonresident clinicians were subanalyzed, certified nursing midwives were the second most likely to screen for FSD (odds ratio [OR], 0.41), followed by nurse practitioners (OR, 0.29) and attending physicians (OR, 0.22). According to multivariable logistic regression techniques, 5 factors were associated with an increased likelihood of a patient being screened for FSD at an annual examination: patient seen by a resident physician rather than an attending physician, patient history of FSD, patient age ≥40 years, patient report of being sexually active at the time of visit, and patient history of cervical procedures., Clinical Implications: There is an opportunity to improve FSD screening rates by clinicians. Future research may assess what factors, such as increased sexual function education or greater incentives to document FSD screening, may result in higher screening rates. From this, targeted and effective interventions might be crafted to improve future screening rates., Strengths and Limitations: This study is one of the first to compare FSD screening rates among clinician types in the same specialty. Study limitations include the inherent limitations of a retrospective design, including selection biases., Conclusion: Residents were more likely to screen for FSD at annual well-woman visits than attending clinicians, nurse practitioners, and certified nurse midwives. Understanding the reasons for varied FSD screening rates among clinician types may aid in the development of strategies to improve screening for this important aspect of women's health., (© The Author(s) 2023.

The layered square-planar nickelates, Nd n+1 Ni n O 2n+2 , are an appealing system to tune the electronic properties of square-planar nickelates via dimensionality; indeed, superconductivity was recently observed in Nd 6 Ni 5 O 12 thin films. Here, we investigate the role of epitaxial strain in the competing requirements for the synthesis of the n = 3 Ruddlesden-Popper compound, Nd 4 Ni 3 O 10 , and subsequent reduction to the square-planar phase, Nd 4 Ni 3 O 8 . We synthesize our highest quality Nd 4 Ni 3 O 10 films under compressive strain on LaAlO 3 (001), while Nd 4 Ni 3 O 10 on NdGaO 3 (110) exhibits tensile strain-induced rock salt faults but retains bulk-like transport properties. A high density of extended defects forms in Nd 4 Ni 3 O 10 on SrTiO 3 (001). Films reduced on LaAlO 3 become insulating and form compressive strain-induced c-axis canting defects, while Nd 4 Ni 3 O 8 films on NdGaO 3 are metallic. This work provides a pathway to the synthesis of Nd n+1 Ni n O 2n+2 thin films and sets limits on the ability to strain engineer these compounds via epitaxy., (© 2023. The Author(s).)

Importance: Acute postoperative urinary retention (POUR) is common after pelvic reconstructive surgery, occurring in 15-45% of women. There is a paucity of data on the relationship between frailty and POUR after prolapse surgery., Objective: This study aimed to examine the association between frailty and POUR in older women who underwent pelvic organ prolapse surgery., Study Design: This secondary analysis of a prospective study of postoperative delirium enrolled women 60 years and older undergoing prolapse surgery. The Fried Frailty Index was used to assess frailty before surgery. Acute POUR was defined as failure to pass a retrograde voiding trial at hospital discharge with postvoid residual volume of greater than 100 mL., Results: Analyses included 165 women, with a mean ± SD age of 72.5 ± 6.1 years and a body mass index of 28.0 ± 4.4 kg/m2. There were 49 laparoscopic/robotic apical suspension procedures (29.7%), 60 vaginal obliterative procedures (36.4%), 47 vaginal apical suspension procedures (28.5%), and 9 isolated anterior and/or posterior colporrhaphies (5.5%), of which 9 had a concomitant incontinence procedure. Seventy-eight women (47.3%) experienced acute POUR. Thirty-one (18.8%) met the criteria for "not frail," 115 (88.5%) were "prefrail," and 19 (11.5%) were "frail." Neither frailty status nor score was associated with POUR. In an analysis of individual Fried Frailty Index components, self-reported unintentional weight loss was significantly associated with POUR (odds ratio, 4.6; 95% confidence interval, 1.23-17.15). This remained significant on multivariable logistic regression (adjusted odds ratio, 4.06; 95% confidence interval, 1.01-16.39)., Conclusions: Frailty was not associated with POUR in older women undergoing prolapse surgery. The observed association between POUR and unintended weight loss before surgery warrants further investigation., Competing Interests: M.F.A. is supported by the National Institute on Aging (R03AG064378-01, K23AG073517-01) and the Pennsylvania Department of Health (4100088553).
