Abstract
This study aimed to determine whether visit-to-visit blood pressure (BP) variability (BPV) is associated with incident frailty. We included 1 394 nonfrail community-dwelling participants aged ≥70 years from the Multidomain Alzheimer Preventive Trial (MAPT) who underwent repeated clinical examinations, including BP and frailty, over a 5-year follow-up period. Systolic BPV (SBPV), diastolic BPV (DBPV), mean arterial pressure variability (MAPV), and pulse pressure variability (PPV) were evaluated using standard deviation (SD), coefficient of variation (CV), average real variability, successive variation, variation independent of mean, and residual SD. Incident frailty was assessed using the Fried phenotype. Cox proportional hazards models were used for the analyses. Higher SBPV was significantly associated with greater risk of frailty (1-SD increase of CV: hazard ratio [HR] = 1.18, 95% confidence interval [CI]: 1.02–1.36) after adjustment for demographics, systolic BP, antihypertensive drugs, body mass index, diabetes, ischemic heart disease, congestive heart failure, stroke, atrial fibrillation, MAPT randomization group, and frailty status. Similar results were observed with all indicators of variability. Higher PPV was associated with a greater risk of developing frailty over time (1-SD increase of CV: HR = 1.17, 95% CI: 1.01–1.35). DBPV and MAPV were not significantly associated with incident frailty. Higher SBPV and PPV were associated with greater risk of incident frailty. Our findings support the concept of BP physiological dysregulation underlying the frail state and suggest that BP instability could be an early marker of frailty.
Nursing Home Competition, Prices, and Quality: A Scoping Review and Policy Lessons
Authors: Yang Ou , Yong Jongsay , Scott Anthony 
Published: April 2021

Abstract

Background and Objectives
In recent years, countries have increasingly relied on markets to improve efficiency, contain costs, and maintain quality in aged care. Under the right conditions, competition can spur providers to compete by offering better prices and higher quality of services. However, in aged care, market failures can be extensive. Information about prices and quality may not be readily available and search costs can be high. This study undertakes a scoping review on competition in the nursing home sector, with an emphasis on empirical evidence in relation to how competition affects prices and quality of care.

Research Design and Methods
Online databases were used to identify studies published in the English language between 1988 and 2020. A total of 50 studies covering 9 countries are reviewed.

Results
The review finds conflicting evidence on the relationship between competition and quality. Some studies find greater competition leading to higher quality, others find the opposite. Institutional features such as the presence of binding supply restrictions on nursing homes and public reporting of quality information are important considerations. Most studies find greater competition tends to result in lower prices, although the effect is small.

Discussion and Implications
The literature offers several key policy lessons, including the relationship between supply restrictions and quality, which has implications on whether increasing subsidies can result in higher quality and the importance of price transparency and public reporting of quality.
Robust Performance of Spider Viscid Silk on Hairy and Smooth Insect Substrates
Authors: Alicea-Serrano Angela M , Onyak Ariel , Dhinojwala Ali , Blackledge Todd A 
Published: April 2021

Abstract
Spider viscid silk adheres to insects in orb webs and is a “smart-adhesive” that quickly changes droplet size, viscosity, and adhesiveness in response to atmospheric humidity. Different species of spiders “tune” water uptake to match the humidity of their foraging environments, achieving a similar “universal” viscosity that optimizes tradeoffs in spreading versus cohesive bulk energy needed to enhance adhesion. Too much water lowers viscosity so that the glue spreads well, but cohesive failure occurs easily, generating poor adhesion. However, the optimal viscosity model of adhesion is based on experiments using smooth glass. Here we test the hypothesis that a less viscous, “over-lubricated” glue, which shows poor adhesion on smooth glass, will be stickier on hairy insects because of its greater ability to spread across three-dimensional rough surfaces. We ran adhesion tests of the furrow spider (Larinioides cornutus [Clerck 1757]) viscid silk on honey bee (Apis mellifera) thorax, with and without hairs, in either high or medium humidity. Our results show that “over-lubricated” glue increases adhesion on hairy surfaces, performing equally as well as an optimally viscous glue.
Anthropogenic Alteration of Flow, Temperature, and Light as Life-History Cues in Stream Ecosystems
Authors: Perkin Elizabeth K , Wilson Matthew J 
Published: April 2021

AbstractLife history events, from mating and voltinism to migration and emergence, are governed by external and historically predictable environmental factors. The ways humans have altered natural environments during the Anthropocene have created myriad and compounding changes to these historically predictable environmental cues. Over the past few decades, there has been an increased interest in the control temperature exerts on life history events as concern over climate change has increased. However, temperature is not the only life history cue that humans have altered. In stream ecosystems, flow and light serve as important life history cues in addition to temperature. The timing and magnitude of peak flows can trigger migrations, decreases in stream temperature may cause a stream insect to enter diapause, and photoperiod appears to prompt spawning in some species of fish. Two or more of these cues may interact with one another in complex and sometimes unpredictable ways. Large dams and increasing impervious cover in urban ecosystems have modified flows and altered the timing of spawning and migration in fish. Precipitation draining hot impervious surfaces increases stream temperature and adds variability to the general pattern of stream warming from climate change. The addition of artificial light in urban and suburban areas is bright enough to eliminate or dampen the photoperiod signal and has resulted in caddisfly emergence becoming acyclical. The resulting changes in the timing of life history events also have the potential to influence the evolutionary trajectory of an organism and its interactions with other species. This paper offers a review and conceptual framework for future research into how flow, temperature, and light interact to drive life history events of stream organisms and how humans have changed these cues. We then present some of the potential evolutionary and ecological consequences of altered life history events, and conclude by highlighting what we perceive to be the most pressing research needs.

AbstractObjectivesThe objectives of this scoping review were to (a) explore how pharmacists perceive their professional roles and identities and (b) describe factors impacting which professional roles or identities pharmacists embody in different pharmacy practice settings.MethodsA scoping review using a deductive approach was undertaken for this study. Systematic searches were conducted in five databases: Ovid MEDLINE, Ovid EMBASE, Ovid PsycINFO, EBSCO Cumulative Index to Nursing and Allied Health and Scopus (Elsevier). Key words searched included pharmacist, identity, professional role and one variations of these. Results were double-blind screened for relevance by two authors. Data extraction was facilitated by the web-based software platform COVIDENCE. Foucauldian critical discourse analysis was used to deconstruct how pharmacists perceive their professional roles and identities.Key findingsIn total, 21 701 articles were retrieved in the search. Following de-duplication and screening, 23 studies from 11 different countries were included. Five major identity themes were identified: Clinician, Dispenser, Business Person, Patient Counsellor and Physician Supporter. The dispenser identity was the most widespread, but it was viewed by many pharmacists as undesirable. The clinician identity also had a strong presence but was viewed as an identity that pharmacists aspire to embody.ConclusionsThis scoping review illustrates that pharmacists do not uniformly perceive themselves to be clinicians. A significant gap exists between the profession’s desired identity and that embodied by practicing pharmacists. The resulting dissonance may be a contributing factor to the lack of wide-scale practice change that the profession has been seeking for decades.
Dielectric breakdown sizes of conducting plates
Authors: Yang Mimi X , Yang Fuqian , Lee Sanboh 
Published: April 2021

AbstractIn this work, we propose mathematical formulations that detail the effect of the dielectric strength of dielectric material on the spatial distribution of electric field in an infinite space with a conducting plate. Using the dielectric strength of air as the maximum limit for the magnitude of electric field intensity and the equivalence of stored charge between two different zones, we determine the size of the dielectric breakdown region (the extended region with ionized material) for the conducting strip and the conducting disk charged to an electric voltage. The size of dielectric breakdown is proportional to the square of the applied voltage, and decreases with the increase of the width/radius of the conducting strip/disk.
Long-Term Trends of Planted Loblolly Pine Diameter Distribution Characteristics
Authors: Green P Corey 
Published: April 2021

AbstractDiameter distributions are fundamental characteristics of stand structure. It is widely assumed that unthinned plantation loblolly pine (Pinus taeda L.) diameter distributions are unimodal and slightly skewed. In this work, the assumption of unimodality is formally tested and confirmed using 413 long-term permanent plots representing three generations of genetics and silviculture across the native range of loblolly pine in the southeastern United States. Approximately 96% of plot measurements had no significant evidence to reject the hypothesis of unimodality. While levels often significantly differed, similar developmental trends of skewness, kurtosis, and estimated Weibull parameters were observed despite the advances of genetics and silviculture. The results of the study indicate the continued need for a flexible distribution for characterizing diameter distributions in plantation loblolly pine.

Abstract
We developed a confidence interval-(CI) assessing model in multivariable normal tissue complication probability (NTCP) modeling for predicting radiation-induced liver disease (RILD) in primary liver cancer patients using clinical and dosimetric data. Both the mean NTCP and difference in the mean NTCP (ΔNTCP) between two treatment plans of different radiotherapy modalities were further evaluated and their CIs were assessed. Clinical data were retrospectively reviewed in 322 patients with hepatocellular carcinoma (n = 215) and intrahepatic cholangiocarcinoma (n = 107) treated with photon therapy. Dose–volume histograms of normal liver were reduced to mean liver dose (MLD) based on the fraction size-adjusted equivalent uniform dose. The most predictive variables were used to build the model based on multivariable logistic regression analysis with bootstrapping. Internal validation was performed using the cross-validation leave-one-out method. Both the mean NTCP and the mean ΔNTCP with 95% CIs were calculated from computationally generated multivariate random sets of NTCP model parameters using variance–covariance matrix information. RILD occurred in 108/322 patients (33.5%). The NTCP model with three clinical and one dosimetric parameter (tumor type, Child–Pugh class, hepatitis infection status and MLD) was most predictive, with an area under the receiver operative characteristics curve (AUC) of 0.79 (95% CI 0.74–0.84). In eight clinical subgroups based on the three clinical parameters, both the mean NTCP and the mean ΔNTCP with 95% CIs were able to be estimated computationally. The multivariable NTCP model with the assessment of 95% CIs has potential to improve the reliability of the NTCP model-based approach to select the appropriate radiotherapy modality for each patient.
Carving Out Space for Equitable Collaborative Research in Protracted Displacement
Authors: Shuayb Maha , Brun Cathrine 
Published: April 2021

AbstractResearch collaborations between global north and south have a long history in studies of forced migration, and discussions of power relations in such research relationships have existed for a long time. We are two researchers working across the global south–north divide, and this article reflects on our attempt to navigate the research industry amid the ‘Syrian refugee research complex’. We discuss our attempt to carve out a space for more equitable research collaborations across the north–south divide and between partners. We unpack the existing power dynamics and the systems attached to them, e.g. institutional constraints, funding regulations, budget restrictions, and residues of post-colonial power dynamics. We then reflect on how these dynamics help to maintain the north’s hegemony in the research and knowledge production cycle. We argue that collaborative research can gain from a reflective practice that focuses on the relational aspects involved in research. This can be achieved through a ‘friendship approach’ rather than ‘tick-the-box guidelines’.
Understanding Food-Related Well-Being in a Diaspora Situation: The Psychological and Social Dimensions
Authors: Al-Sayed Lubana , Bieling Claudia 
Published: April 2021

AbstractFood and related practices have a substantial impact on the well-being of individuals. When people are forced to migrate, it is unclear how this affects and potentially reshapes their understanding of food-related well-being. By drawing upon 34 semi-structured interviews with Syrian refugees in Stuttgart, Germany, this article presents an in-depth investigation of the psychological and social dimensions of food-related well-being in a diaspora situation. Interview partners express a strong affinity to their past food-related life and a constant comparison between what they are used to and what is currently available to them in the new food environment. Moreover, participants articulate a low autonomy and weak environmental mastery over food choices, which plays out differently according to the stage of displacement. Food is important for building new bridges with the host community and expressing social identities. The insights gained from this research are useful to design strategies to promote the well-being of refugees.

Abstract
Adrenal cysts are usually non-functional and asymptomatic. Cystic pheochromocytomas are a rare clinical entity and difficult to differentiate from simple cysts in the absence of classic clinical symptoms. Few cases of cystic pheochromocytomas have been reported in the literature. We present a case of a huge cystic pheochromocytoma in 70-year-old men who presented with a large retroperitoneal cystic mass and discuss difficulties of diagnostic and treatment.
Irreducible inflamed inguinal hernia with infected gangrenous omentum after laparoscopic appendectomy: a case report
Authors: Awed Andro Adel , Hasoon Haider Ali , Meanji Farid Ahmed , Duhmaj Mostafa Bader , Alamri Khalid Saeed 
Published: April 2021

Abstract
We reported a rare complication of laparoscopic appendectomy in a 19-year-old patient, who was admitted with acute appendicitis and had no history of inguinal hernia. He underwent laparoscopic appendectomy for suppurative appendicitis. Eight days later, he presented with irreducible incarcerated right inguinal hernia. A non-manifested congenital inguinal hernial sac has been symptomized after laparoscopic gas inflation inside the peritoneal cavity, which resulted in widening of the internal inguinal ring and protrusion of the omentum. Besides that, the omental content became inflamed and gangrenous as a consequence of the suppurative appendicitis and the presence of purulent fluid in the pelvis. Therefore, there were two complications that occurred simultaneously after laparoscopic appendectomy: a manifested right inguinal hernia and incarceration and gangrene of its contents. To our knowledge, this is the first reported case of irreducible inflamed inguinal hernia manifested for the first time after laparoscopic appendectomy.
On White Theology … and other Lies: Redemptive Communal Narrative in Toni Morrison’s Beloved
Authors: Allen John J. 
Published: April 2021

Abstract
Toni Morrison’s Beloved can be read as a decidedly theological work, particularly in its expression of redemptive communal unity through narrative re-telling. Morrison’s imagined community in Beloved moves from fragmented isolation to liberative solidarity with each other, dramatically exemplifying a postcolonial theological vision, which draws from African traditional cultures. Although often rejected by some theological interpreters as ‘pop-gnostic’, Toni Morrison’s Beloved rejects a theological worldview of coloniality and offers instead a hybridised approach to theological meaning. In dispelling the racial ‘othering’ that frequently occurs in both literature and theology, Morrison crafts a theological narrative that retells the sinful past in the hope of transcending guilt for the sake of a harmonious future. Thus, the theological insight of Beloved is found in a syncretic cosmology that does not perpetuate colonial ontological categories but forges a communal narrative that is non-possessive and open to a future free from the shackles of the past. Morrison’s Beloved equips the theologian with pertinent questions, ones that wrestle with the presence of God within a suffering and oppressed community; these are timely questions that must be posed to the Christian tradition in order to transcend the lies of white theology.
It is still PCP that can stand for Pneumocystis pneumonia: Appeal for generalized use of only one acronym
Authors: Nevez Gilles , Totet Anne , Matos Olga , Calderon Enrique J , Miller Robert F , Le Gal Solène 
Published: April 2021

Abstract

Twenty-years ago, considering the host specificity of Pneumocystis species, the human-derived Pneumocystis, Pneumocystis carinii formae specialis hominis, was renamed Pneumocystis jirovecii. Pneumocystis carinii formae specialis carinii was finally renamed Pneumocystis carinii and kept for the species derived from Rattus norvegicus. P. jirovecii is now widely used by most authors. The PCP acronym that initially referred to “Pneumocystis cariniipneumonia” was contemporaneously redefined to stand for Pneumocystispneumonia in order to avoid changing the acronym of the name of the disease that clinicians have used for several decades. Using analysis of multidata bases on PubMed, we have noted a recent acceleration in the use of PJP for Pneumocystis jiroveciipneumonia, which may be grammatically correct but not in accordance with retaining PCP, which was proposed in the early 2000s. Through this reminder, in order to standardize the literature on P. jirovecii, we plead for the use of only one acronym, PCP.

Lay Summary
Through this reminder on Pneumocystis nomenclature, we plead for the use of only one acronym, PCP, the retention of which was proposed in the early 2000s, and which currently stands for Pneumocystispneumonia.

ABSTRACT
We present a supermassive black hole (SMBH) mass measurement in the Seyfert 1 galaxy NGC 7469 using Atacama Large Millimeter/submillimeter Array (ALMA) observations of the atomic-[CI](1–0) and molecular-12CO(1–0) emission lines at the spatial resolution of ≈0${_{.}^{\prime\prime}}$3 (or ≈100 pc). These emissions reveal that NGC 7469 hosts a circumnuclear gas disc (CND) with a ring-like structure and a two-arm/bi-symmetric spiral pattern within it, surrounded by a starbursting ring. The CND has a relatively low σgas/V ≈ 0.35 (r ≲ 0${_{.}^{\prime\prime}}$5) and ≈0.19 (r &gt; 0${_{.}^{\prime\prime}}$5), suggesting that the gas is dynamically settled and suitable for dynamically deriving the mass of its central source. As is expected from X-ray dominated region (XDR) effects that dramatically increase an atomic carbon abundance by dissociating CO molecules, we suggest that the atomic [CI](1–0) emission is a better probe of SMBH masses than CO emission in active galactic nuclei (AGNs). Our dynamical model using the [CI](1–0) kinematics yields a $M_{\rm BH}=1.78^{+2.69}_{-1.10}\times 10^7$ M⊙ and $M/L_{\rm F547M}=2.25^{+0.40}_{-0.43}$ (M⊙/L⊙). The model using the 12CO(1–0) kinematics also gives a consistent MBH with a larger uncertainty, up to an order of magnitude, i.e. $M_{\rm BH}=1.60^{+11.52}_{-1.45}\times 10^7$ M⊙. This newly dynamical MBH is ≈2 times higher than the mass determined from the reverberation mapped (RM) method using emissions arising in the unresolved broad-line region (BLR). Given this new MBH, we are able to constrain the specific RM dimensionless scaling factor of $f=7.2^{+4.2}_{-3.4}$ for the AGN BLR in NGC 7469. The gas within the unresolved BLR thus has a Keplerian virial velocity component and the inclination of $i\approx {11.0^\circ }_{-2.5}^{+2.2}$, confirming its face-on orientation in a Seyfert 1 AGN by assuming a geometrically thin BLR model.
