Published: October 2021

Background

Diagnosing partial tears of the medial meniscus (MM) posterior root is difficult. The aim of this study was to evaluate diagnostic values involved in conventional magnetic resonance imaging (MRI) features of MM posterior root tears (MMPRTs) and find other MRI-based findings in patients with partial MMPRTs.

Methods

Eighteen patients who had arthroscopically confirmed partial MMPRTs were included. As a control, 18 patients who underwent partial meniscectomy for other types of MM tears were evaluated. Isolated partial MMPRTs were classified into the following three types: type A, accurate partial stable tear (cleavage < 1/2 of root width); type B, bridged unstable root tear (cleavage ≥ 1/2 of root width); type C, complex horn tear expanded to the root. Conventional MRI-based findings of MMPRTs were evaluated between two groups (n = 23). Posterior root irregularity, bone marrow spot, and ocarina-like appearance showing several condensed circles in triangular meniscal horn (ocarina sign) were also evaluated.

Results

Posterior root irregularity and bone marrow spot were frequently observed in the partial MMPRTs (47.8%), compared with the other MM tears (P = 0.007 and 0.023, respectively). The ocarina sign was detected in 69.6% of patients with partial MMPRTs. A significant difference between two groups was observed in a positive ratio of ocarina sign (P < 0.001). Types A, B, and C of the partial tear/damage were observed in three, eight, and seven patients, respectively. The ocarina sign was the most common MRI finding in each type of partial MMPRT.

Conclusions

This study demonstrated that a characteristic MRI finding, “ocarina sign,” was frequently observed in patients with partial tear/damage of the MM posterior root. The ocarina sign was the most common MRI finding in several types of partial MMPRTs. Our results suggest that the ocarina sign may be useful to diagnose unnoticed partial MMPRTs.

Published: October 2021

Background

Burnout is a work-related physical and/or emotional exhaustion among individuals working in the human service sector. This descriptive cross-sectional study aimed to estimate the prevalence of burnout among interns training in different hospitals in Riyadh, Saudi Arabia, and its relation to engaging in unethical behaviors.

Results

The study found a high burnout level in 135 (50%) of the interns with minimal overall engagement in unethical behaviors (5.9%). However, patient-related burnout was the only factor found with a highly significant association to engagement in unethical behaviors (P-value < 0.001).

Conclusions

This study demonstrated a high prevalence of burnout among interns with a significant association between patient-related burnout and the engagement in unethical behaviors. That was a worrying sign that needs further evaluation in future research, including the other risk factors, to prevent/improve burnout and to limit the unprofessional behaviors.
Rapid-cycle systems modeling to support evidence-informed decision-making during system-wide implementation
Authors: Sheldrick R. Christopher , Cruden Gracelyn , Schaefer Ana J. , Mackie Thomas I.
Published: October 2021

Background

To “model and simulate change” is an accepted strategy to support implementation at scale. Much like a power analysis can inform decisions about study design, simulation models offer ananalytic strategyto synthesize evidence that informs decisions regarding implementation of evidence-based interventions. However, simulation modeling is under-utilized in implementation science. To realize the potential of simulation modeling as animplementation strategy, additional methods are required to assist stakeholders to use models to examine underlying assumptions, consider alternative strategies, and anticipate downstream consequences of implementation. To this end, we propose Rapid-cycle Systems Modeling (RCSM)—a form of group modeling designed to promote engagement with evidence to support implementation. To demonstrate its utility, we provide an illustrative case study with mid-level administrators developing system-wide interventions that aim to identify and treat trauma among children entering foster care.

Methods

RCSM is an iterative method that includes three steps per cycle: (1) identify and prioritize stakeholder questions, (2) develop or refine a simulation model, and (3) engage in dialogue regarding model relevance, insights, and utility for implementation. For the case study, 31 key informants were engaged in step 1, a prior simulation model was adapted for step 2, and six member-checking group interviews (n= 16) were conducted for step 3.

Results

Step 1 engaged qualitative methods to identify and prioritize stakeholder questions, specifically identifying a set of inter-related decisions to promote implementing trauma-informed screening. In step 2, the research team created a presentation to communicate key findings from the simulation model that addressed decisions about programmatic reach, optimal screening thresholds to balance demand for treatment with supply, capacity to start-up and sustain screening, and availability of downstream capacity to provide treatment for those with indicated need. In step 3, member-checking group interviews with stakeholders documented the relevance of the model results to implementation decisions, insight regarding opportunities to improve system performance, and potential to inform conversations regarding anticipated implications of implementation choices.

Conclusions

By embedding simulation modeling in a process of stakeholder engagement, RCSM offers guidance to realize the potential of modeling not only as an analytic strategy, but also as an implementation strategy.
Preparation and characterization of BSA as a model protein loaded chitosan nanoparticles for the development of protein-/peptide-based drug delivery system
Authors: Yadav Preeti , Yadav Awadh Bihari
Published: October 2021

Background

The purpose of this study was to develop protein-/peptide-loaded nanoparticle-based delivery system, which can efficiently deliver therapeutic molecules to the lung via pulmonary delivery. The chitosan nanoparticles were prepared by the ionic gelation method, and bovine serum albumin was used as a model protein. These nanoparticles were characterized for size, zeta potential, encapsulation efficiency, cell cytotoxicity, uptake study, release profile and size distribution and uniformity. The chemical interaction of chitosan and protein was studied by XRD and FTIR. The integrity assessment of encapsulated protein into nanoparticle was studied by native and SDS-PAGE gel electrophoresis.

Results

The size and zeta potential of BSA nanoparticles were 193.53 ± 44.97 to 336.36 ± 94.63 and 12.73 ± 0.41 to 18.33 ± 0.96, respectively, with PDI values of 0.35–0.45. The encapsulation efficiency was in the range of 80.73 ± 6.37% to 92.34 ± 1.72%. The cumulative release of the BSA from the nanoparticles was 72.56 ± 6.67% in 2 weeks. The BSA-loaded nanoparticles showed good uptake and no significant cytotoxicity observed into the A549 cell line. In this study, it was also observed that during nanoparticles’ synthesis protein structure and integrity is not compromised. The nanoparticles showed controlled and sustained release with initial burst release. In TEM images, it was shown that nanoparticles’ distribution is uniform within nanometre range.

Conclusion

From this study, it was concluded that nanoparticles prepared by this method are suitable to deliver protein/peptide into the cells without any degradation of protein during process of nanoparticle fabrication.
Computational guided identification of potential leads from Acacia pennata (L.) Willd. as inhibitors for cellular entry and viral replication of SARS-CoV-2
Authors: Zothantluanga James H. , Gogoi Neelutpal , Shakya Anshul , Chetia Dipak , Lalthanzara H.
Published: October 2021

Background

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) started in 2019 and is still an on-going pandemic. SARS-CoV-2 uses a human protease called furin to aid in cellular entry and its main protease (Mpro) to achieve viral replication. By targeting these proteins, scientists are trying to identify phytoconstituents of medicinal plants as potential therapeutics for COVID-19. Therefore, our study was aimed to identify promising leads as potential inhibitors of SARS-CoV-2 Mproand furin using the phytocompounds reported to be isolated fromAcacia pennata(L.) Willd.

Results

A total of 29 phytocompounds were reported to be isolated fromA. pennata. Molecular docking simulation studies revealed 9 phytocompounds as having the top 5 binding affinities towards SARS-CoV-2 Mproand furin. Among these phytocompounds, quercetin-3-O-α-L-rhamnopyranoside (C_18), kaempferol 3-O-α-L-rhamnopyranosyl-(1 → 4)-β-D-glucopyranoside (C_4), and isovitexin (C_5) have the highest drug score. However, C_18 and C_4 were not selected for further studies due to bioavailability issues and low synthetic accessibility. Based on binding affinity, molecular properties, drug-likeness, toxicity parameters, ligand interactions, bioavailability, synthetic accessibility, structure–activity relationship, and comparative analysis of our experimental findings with other studies, C_5 was identified as the most promising phytocompound. C_5 interacted with the active site residues of SARS-CoV-2 Mpro(GLU166, ARG188, GLN189) and furin (ASN295, ARG298, HIS364, THR365). Many phytocompounds that interacted with these amino acid residues were reported by other studies as potential inhibitors of SARS-CoV-2 Mproand furin. The oxygen atom at position 18, the –OH group at position 19, and the 6-C-glucoside were identified as the pharmacophores in isovitexin (also known as apigenin-6-C-glucoside). Other in-silico studies reported apigenin as a potential inhibitor of SARS-CoV-2 Mproand apigenin-o-7-glucuronide was reported to show stable conformation during MD simulations with SARS-CoV-2 Mpro.

Conclusion

The present study found isovitexin as the most promising phytocompound to potentially inhibit the cellular entry and viral replication of SARS-CoV-2. We also conclude that compounds having oxygen atom at position 18 (C-ring), –OH group at position 19 (A-ring), and 6-C-glucoside attached to the A-ring at position 3 on a C6–C3–C6flavonoid scaffold could offer the best alternative to develop new leads against SARS-CoV-2.
Disciplining the Bodies of Single Women
Authors: Martin Morag
Published: October 2021

Starting in 1802, the Napoleonic government promoted the education of enlightened midwives through both the Parisian Maternité and departmental schools. The Gers, in the southwest, repeatedly tried and failed to open a school that would graduate well-trained midwives. Its failure by 1839 rested on the male authorities' inability to conceive of and support spaces where three interrelated groups of women could cohabitate safely in this rural and Catholic department. Young, innocent midwifery students needed protection from the mostly unwed mothers available as bodies for practice. In turn, both the unwed mothers and the midwifery students, due to their knowledge of procreation, threatened the purity of the nursing sisters who controlled charitable spaces. Ultimately, despite attempts to redefine the bodies of unwed mothers and reconfigure the spaces to run a legitimate school, the authorities abandoned the goal of providing skilled midwives for the women in labor who needed them most.

A partir de 1802, le gouvernement napoléonien a promu la formation de sages-femmes à travers l’école de la Maternité à Paris et des écoles départementales. Le Gers a essayé à plusieurs reprises, mais en vain, d'ouvrir une école qui formerait des sages-femmes diplômées. Son échec repose sur l'incapacité des autorités masculines de ce département rural et catholique à concevoir la coopération et la cohabitation de trois groupes de femmes : les étudiantes sages-femmes, les religieuses, et les filles-mères. Les étudiantes sages-femmes—jeunes, innocentes, et célibataires—avaient besoin de protection contre la contamination morale des filles-mères dont les corps étaient nécessaires pour l'instruction. A leur tour, les filles-mères et les étudiantes, en raison de leur connaissance de la procréation, menaçaient la pureté des sœurs infirmières qui contrôlaient les hospices. En fin de compte, malgré les tentatives de redéfinir le corps des mères célibataires et de réaménager les hospices pour créer une école légitime, les autorités ont fini par abandonner l'objectif de former des sages-femmes diplômées pour servir les femmes en couches qui en avaient le plus besoin.
The “Nature” of American Literature: Race, Place, and Textuality in John Crowe Ransom and Elizabeth Madox Roberts
Authors: Kunde Sharon
Published: October 2021

“The ‘Nature’ of American Literature” explores how John Crowe Ransom and his less-studied contemporary Elizabeth Madox Roberts advanced a theory of literary objects that emerged from nature itself. This theory formed the basis of Ransom’s bid, in “Criticism, Inc.,” for disciplinary stratification and productivity. Through a set of representational practices this article gathers under the terms “natural reading” and “natural writing,” Roberts and Ransom framed valuable aesthetic objects as the product of a carefully cultivated relationship between human observers and landscape. For both, however, this rarified relationship was grounded in and served to reinforce racial hierarchy. Even as the discipline turns away from the cultural elitism associated with New Criticism, Ransom’s understanding of the literary object as natural and thus subject to disciplinary study continues to inform contemporary critical practice. This article thus invites engagement with the often submerged racial politics of the ways we constitute objects and processes of disciplinary literary studies.
Dadaism and Classicism inThe Waste Land
Authors: Eichholz Patrick
Published: October 2021

Out of the wreckage of the First World War, classicism and dadaism charted two opposing paths forward. While one movement sought to overturn the institutions complicit in prolonging the war, the other sought to buttress these same institutions as a safeguard against the chaos of modern life. This essay studies the peculiar convergence of these contradictory movements in The Waste Land. The article provides a full account of Eliot’s postwar engagement with dadaism and classicism before examining the influence of each movement on The Waste Land. Walter Benjamin’s theory of baroque allegory will be introduced in the end to address the article’s central question: How can any one poem be both classicist and dadaist at the same time?
Unintended Lessons of Revolution
Authors: Padilla Tanalís
Published: October 2021

In the 1920s, Mexico established rural normales—boarding schools that trained teachers in a new nation-building project. Drawn from campesino ranks and meant to cultivate state allegiance, their graduates would facilitate land distribution, organize civic festivals, and promote hygiene campaigns. In Unintended Lessons of Revolution, Tanalís Padilla traces the history of the rural normales, showing how they became sites of radical politics. As Padilla demonstrates, the popular longings that drove the Mexican Revolution permeated these schools. By the 1930s, ideas about land reform, education for the poor, community leadership, and socialism shaped their institutional logic. Over the coming decades, the tensions between state consolidation and revolutionary justice produced a telling contradiction: the very schools meant to constitute a loyal citizenry became hubs of radicalization against a government that increasingly abandoned its commitment to social justice. Crafting a story of struggle and state repression, Padilla illuminates education's radical possibilities and the nature of political consciousness for youths whose changing identity—from campesinos, to students, to teachers—speaks to Mexico’s twentieth-century transformations.
Plantation Life
Authors: Li Tania Murray , Semedi Pujo
Published: October 2021

In Plantation Life Tania Murray Li and Pujo Semedi examine the structure and governance of Indonesia's contemporary oil palm plantations in Indonesia, which supply 50 percent of the world's palm oil. They attend to the exploitative nature of plantation life, wherein villagers' well-being is sacrificed in the name of economic development. While plantations are often plagued by ruined ecologies, injury among workers, and a devastating loss of livelihoods for former landholders, small-scale independent farmers produce palm oil more efficiently and with far less damage to life and land. Li and Semedi theorize “corporate occupation” to underscore how massive forms of capitalist production and control over the palm oil industry replicate colonial-style relations that undermine citizenship. In so doing, they question the assumption that corporations are necessary for rural development, contending that the dominance of plantations stems from a political system that privileges corporations.
Convergent validity and reliability of a novel repeated agility protocol in junior rugby league players
Authors: Nicholls Anthony , Leicht Anthony , Connor Jonathan , Halliday Aaron , Doma Kenji
Published: October 2021

Background: : Rugby league involves repeated, complex, and high intensity change-of-direction (COD) movements with no existing test protocols that specifically assesses these multiple physical fitness components simultaneously. Thus, the current study examined the convergent validity of a repeated Illinois Agility (RIA) protocol with the repeated T-agility protocol, and the repeatability of the RIA protocol in adolescent Rugby League players. Furthermore, aerobic capacity and anaerobic and COD performance were assessed to determine whether these physical qualities were important contributors to the RIA protocol.

Methods: Twenty-two junior Rugby League players completed 4 sessions with each separated by 7 days. Initially, physical fitness characteristics at baseline (i.e., Beep test,, countermovement jump, 30-m sprint, single-effort COD and repeated sprint ability [RSA]) were assessed. The second session involved a familiarisation of RIA and repeated T-agility test (RTT) protocols. During the third and fourth sessions, participants completed the RIA and RTT protocols in a randomised, counterbalanced design to examine the validity and test-retest reliability of these protocols.

Results: For convergent validity, significant correlations were identified between RIA and RTT performances (r= >0.80; p<0.05). For contributors to RIA performance, significant correlations were identified between all baseline fitness characteristics and RIA (r = >0.71; p < 0.05). Reliability of the RIA protocol was near perfect with excellent intra-class correlation coefficient (0.87-0.97), good ratio limits of agreement (×/÷ 1.05-1.06) and low coefficient of variations (1.8-2.0%).

Conclusions: The current study has demonstrated the RIA to be a simple, valid and reliable field test for RL athletes that can provide coaches with information about their team’s ability to sustain high intensity, multi-directional running efforts.
Medicinal properties of Morus alba for the control of type 2 diabetes mellitus: a systematic review
Authors: Morales Ramos Jorge Guillermo , Esteves Pairazamán Ambrocio Teodoro , Mocarro Willis María Ema Soledad , Collantes Santisteban Samuel , Caldas Herrera Emma
Published: October 2021

Background: The objective of this review was to evaluate the medicinal potential of Morus alba leaves on the control of type 2 diabetes mellitus (DM2). The research question was: what is the therapeutic potential of Morus alba leaves for the control of DM2?

Methods: This systematic review was based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The included studies were extracted from Scopus, Pubmed, ScienceDirect, Scielo, and Google Scholar; January 2015 to July 2021. Key search terms were MeSH and DeCS: Morus alba, mulberry, hypoglycemic agent. The inclusion criteria were: studies in rats administered Morus alba leaf extracts; studies that included the dimensions of lipidemia and glycemia; studies that included indicators such as fasting glucose, postprandial glucose, glycosylated hemoglobin, triglycerides, low-density lipoproteins, total cholesterol, and insulin resistance. Exclusion criteria: studies in which Morus alba leaves were administered with other plants; studies with other parts of the Morus alba plant; proteomic studies, cancer, duplicate studies, in vitro studies, and evaluation of included studies. All included investigations were evaluated for biases.

Results: Of 253 studies found, 29 were included. The extracts of Morus alba leaves at the phytochemical level improve glucose uptake. Chlorogenic acid, isoquercitrin, and quercitrin, present in the leaves of Morus alba, have hypoglycemic properties and an ameliorating effect on diabetic nephropathy. This leaf has pharmacological effects such as glucose absorption, insulin secretion production, antioxidant and anti-inflammatory agent, antihyperglycemic and antihyperlipidemic activities, and obesity management.

Conclusions: Morus alba leaves have pharmacological effects on DM2 that include glucose absorption, production of insulin secretion, antioxidant agent, antihyperglycemic and antihyperlipidemic activities, and obesity control. Beyond these results, there is a lack of studies on the potential and synergistic effects of Morus alba leaves' components, limiting the possibility of a more effective therapy using the plant's leaves.

Midwives' perceptions of disrespect and abuse of women during labour and childbirth in Lusaka, Zambia
Authors: Nankamba Namayipo Stella Wamukankamba , Ngoma Catherine Mubita , Makoleka Maureen Masumo
Published: October 2021

Background/Aims

Disrespect and abuse is a frequent occurrence in labour wards around the world. Disrespect and abuse during care by health workers can prevent pregnant women from seeking care during labour and childbirth, which can lead to increased maternal and neonatal mortality rates. This study aimed to explore midwives' perceptions of disrespect and abuse of women during labour and childbirth in Lusaka.

Methods

A concurrent convergent mixed-method approach was used for this study. Data were collected through a self-administered questionnaire given to 217 midwives actively practicing in maternal health services across Lusaka randomly sampled for the quantitative arm of the study. The data were analysed using bivariate and multivariate logistic regression, with P<0.05 used to indicate significance. For the qualitative component of the study, 13 purposively selected key informants were interviewed with an interview guide.

Results

Most of the respondents (88.5%) perceived disrespect and abuse of women during labour and childbirth as a negative phenomenon. However, almost half (40.1%) had provided care which was disrespectful and abusive during their practice and the majority (68.7%) had observed disrespect and abuse by other midwives. Bivariate and multivariate logistic regression analysis found an association between midwives' perception of disrespect and abuse and witnessing or participating in disrespectful and abusive behaviour during practice. In the qualitative arm of the study, midwives reported that disrespect and abuse occurred in labour wards across Lusaka, demonstrating an urgent need to prevent such practices. Midwives suggested actions such as increased sensitisation and training of midwives on respectful maternity care and improved staffing levels as ways to prevent this practice

Conclusions

Disrespect and abuse of women during labour and childbirth should be prevented. Increasing health education and training for both the public and midwives on respectful maternity care can help to achieve this goal. Midwives need to be motivated through good working environments, increased wages and increased time to rest while working, as the heavy workload was found to contribute to disrespect and abuse in labour wards.
Microcirculatory changes and thrombotic complications in COVID-19
Authors: Das Saroj
Published: October 2021

Despite its many devastating effects, the COVID-19 pandemic has had a positive impact in the ways in which society, scientific institutions, governing bodies, businesses, educational organisations, and communication have functioned unchallenged over the years. Rapid advancement in science enabled identification and characterisation of the virus and in developing vaccines to combat the disease. The mysterious ways in which the virus attacks the vital organs that lead on to multiorgan failure and thrombosis of the arterial and venous system have also been revealed. The ability to study the microcirculatory changes at the bedside and predict prognosis is a way forward. All the evidence suggests that the outcome of COVID-19 infection is related to the severity of the disease seen in the intensive care unit setting. This article discusses microcirculatory changes and immune coagulopathy caused by COVID-19.

Authors: Dodel Khadijeh , Ozgoli Giti , Premberg Aasa , Ghasemi Nillofar , Mobarakabadi Sedigheh Sedigh , Pazandeh Farzaneh
Published: October 2021

Background/Aims

The presence of fathers during labour and birth can have favourable outcomes for the health of the mother, father and infant. However, there are few studies on fathers' experiences while being present during labour and birth, which necessitates the development of a valid questionnaire for this purpose. The aim of this study was to translate and culturally adapt the first time fathers questionnaire into Persian.

Methods

A total of 220 first-time fathers at private midwifery counseling centers were given a translated questionnaire to complete. Forward-backward translation of the questionnaire was conducted and content, face and construct validity were examined. After extracting factors and item distribution, confirmatory factor analysis was performed. Cronbach's alpha was used for reliability.

Results

A valid 19-item questionnaire with four dimensions, ‘worry’, ‘acceptance and support during labor’, ‘support during and after birth’, and ‘preparedness’ was obtained. The Cronbach's alpha was 0.78.

Conclusions

The Persian questionnaire is valid and reliable for examining the experiences of first-time fathers. It can be employed to evaluate fathers' experiences during labour and birth in midwifery services planning to promote quality of care during childbirth.
The Rationality of Compiling a Forest Resource Balance Sheet
Authors: Lin Meng , Jin Lijun , Tian Guoshuang
Published: October 2021

The existing forest resource accounting system is limited to the valuation of wood and forest products; the service value of the forest resource ecosystem is not yet included. This study adopts an empirical approach to studying the rationality and influencing factors of compiling a forest resource balance sheet (FRBS). An FRBS can systematically reflect the contribution of forest resources to the economy, ecology, and society in terms of both physical quantity and value quantity. A questionnaire survey was used to collect the data. We found that the determination and measurement of forest resource assets and liabilities and the calculation of the service value of the ecosystem had a supporting effect on the rationality of compiling an FRBS. This study expands the field and scope of forest resource accounting, facilitates the compilation of natural resources and government balance sheets, and presents the practical significance for the theory and practice behind the development of an FRBS.
The state of the leprosy epidemic in Yunnan, China 2011–2020: A spatial and spatiotemporal analysis, highlighting areas for intervention
Authors: Chen Xiaohua , Shui Tie-Jun
Published: October 2021

Background

Despite public health efforts to reduce the leprosy burden in Yunnan, China, leprosy remains an important public health problem in some specific areas. We analyzed the epidemiological characteristics and spatial distribution of leprosy in Yunnan, China, and provide data to guide disease prevention and control efforts.

Methodology/principal findings

The surveillance data of newly detected leprosy cases in Yunnan, China, during 2011–2020 were extracted from the LEPROSY MANAGEMANT INFORMATION SYSTEM IN CHINA (LEPMIS), and spatial distribution analysis, spatial autocorrelation analysis, and spatiotemporal scanning were performed with ArcGIS 10.6.1, GeoDa 1.8.8, and SaTScan 9.4.3 software, respectively. A total of 1907 newly detected leprosy cases were reported in Yunnan, China, during 2011–2020. The new case detection rate (NCDR) decreased from 0.62 in 2011 to 0.25 in 2020, with an annual incidence of 0.41/100,000 population. The proportions of multibacillary (MB) cases, cases in female patients, cases causing grade 2 physical disability (G2D), and cases in pediatric patients were 67.07%, 33.93%, 17.99%, and 2.83%, respectively. The number of counties with an incidence above 1/100,000 population decreased from 30 in 2011 to 8 in 2020. The Moran’s I of leprosy in Yunnan, China, during 2011–2020 ranged from 0.076 to 0.260, indicating the presence of spatial clusters. Local spatial autocorrelation (LSA) analysis showed that high-high cluster areas (hot spots) were mainly distributed in the southeastern, northern, and northwestern regions. Spatiotemporal scanning showed three clusters with high NCDRs. The probably primary clusters, occurring during January 1, 2011–December 31, 2015, covered 11 counties in the southeastern region (RR = 5.046515, LRR = 271.749664, P = 0.000).

Conclusion

The number of leprosy cases in Yunnan decreased overall, although some high-NCDR regions remained. Geographic information system (GIS) analysis coupled with spatial analysis indicated regions with leprosy clusters. Continuous leprosy prevention and control strategies in Yunnan Province should be established, and interventions in high-risk regions should be prioritized and further strengthened.
Bird nests as botanical time capsules: DNA barcoding identifies the contents of contemporary and historical nests
Authors: Rinkert Alex , Misiewicz Tracy M. , Carter Benjamin E. , Salmaan Aleezah , Whittall Justen B.
Published: October 2021

Bird nests in natural history collections are an abundant yet vastly underutilized source of genetic information. We sequenced the nuclear ribosomal internal transcribed spacer to identify plant species used as nest material in two contemporary (2003 and 2018) and two historical (both 1915) nest specimens constructed by Song Sparrows (Melospiza melodia) and Savannah Sparrows (Passerculus sandwichensis). A total of 13 (22%) samples yielded single, strong bands that could be identified using GenBank resources: six plants (Angiospermae), six green algae (Chlorophyta), and one ciliate (Ciliophora). Two native plant species identified in the nests includedFestuca microstachys, which was introduced to the nest collection site by restoration practitioners, andRosa californica, identified in a nest collected from a lost habitat that existed about 100 years ago. Successful sequencing was correlated with higher sample mass and DNA quality, suggesting future studies should select larger pieces of contiguous material from nests and materials that appear to have been fresh when incorporated into the nest. This molecular approach was used to distinguish plant species that were not visually identifiable, and did not require disassembling the nest specimens as is a traditional practice with nest material studies. The many thousands of nest specimens in natural history collections hold great promise as sources of genetic information to address myriad ecological questions.
The critical role of natural forest as refugium for generalist species in oil palm-dominated landscapes
Authors: Guerrero-Sanchez Sergio , Goossens Benoit , Saimin Silvester , Orozco-terWengel Pablo
Published: October 2021

In Borneo, oil palm plantations have replaced much of natural resources, where generalist species tend to be the principal beneficiaries, due to the abundant food provided by oil palm plantations. Here, we analyse the distribution of the Asian water monitor lizard (Varanus salvator) population within an oil palm-dominated landscape in the Kinabatangan floodplain, Malaysian Borneo. By using mark-recapture methods we estimated its population size, survival, and growth in forest and plantation habitats. We compared body measurements (i.e. body weight and body length) of individuals living in forest and oil palm habitats as proxy for the population’s health status, and used general least squares estimation models to evaluate its response to highly fragmented landscapes in the absence of intensive hunting pressures. Contrary to previous studies, the abundance of lizards was higher in the forest than in oil palm plantations. Recruitment rates were also higher in the forest, suggesting that these areas may function as a source of new individuals into the landscape. While there were no morphometric differences among plantation sites, we found significant differences among forested areas, where larger lizards were found inhabiting forest adjacent to oil palm plantations. Although abundant in food resources, the limited availability of refugia in oil palm plantations may intensify intra-specific encounters and competition, altering the body size distribution in plantation populations, contrary to what happens in the forest. We conclude that large patches of forest, around and within oil palm plantations, are essential for the dynamics of the monitor lizard population in the Kinabatangan floodplain, as well as a potential source of individuals to the landscape. We recommend assessing this effect in other generalist species, as well as the impact on the prey communities, especially to reinforce the establishment of buffer zones and corridors as a conservation strategy within plantations.

Introduction: The press is one of the most effective methods to provide the public with health education and to increase knowledge levels related to health in society.Nutritional advice and weight loss diets are also frequently featured in newspapers. However, diets in newspaper limit food groups and/or nutrients to achieve faster results.This study aimed to assess diet lists published in newspapers in terms of energy andnutrient contents and to compare levels with requirements.
Material and Methods: From 1 February 2018 to 31 January 2019, nutritional and diet news included in 10 newspapers with high circulation in Turkey were investigated and diets published in these newspapers were investigated. The energy, macro, and micronutrient contents were compared with the Turkey Nutrition Guide recommendations.
Results: It appeared diet lists met 55.5% of energy requirements for women and 44.5% of energy requirements for men. Carbohydrate and protein contents of diets were below recommendations, while fat contents were identified to be above-recommended levels. Dietary fiber was determined to meet 81.2% of recommendations. For micronutrients, calcium and iron contents were below recommended levels.
Conclusions: It appears weight-loss diets in newspapers are insufficient in terms of energy and some nutrients. Though these diets, which are easily accessible by a large portion of society, without expert control they may cause nutrient deficiencies in the long term.

Introduction: Futsal is a sport that requires nutritional support to support the high-energy expenditure and significant loss of fluids and electrolytes during training and matches. It is important that high-level athletes follow appropriate, evidence-based nutrition. To our knowledge, there is a lack of data on the eating habits and nutrition knowledge of Futsal players. Therefore, this study aims to describe the nutritional knowledge and eating habits of players of the national Brazilian Futsal Team. A secondary aim was to translate the Abridged Nutrition for Sport Questionnaire into Portuguese for use in Portuguese-speaking athletes.
Material and methods: This is a cross-sectional and descriptive study. The evaluations were carried out during the preparation period of the Brazilian Futsal Team for the FIFA Futsal World Cup 2020 qualifiers.  We evaluated anthropometry (weight, height, body mass index) nutritional knowledge (assessed using a translated version of the Abridged Nutrition for Sport Knowledge Questionnaire) and eating habits (assessed using a validated Brazilian FFQ), as well as supplement use. The translation of the ANSKQ was undertaken using previous validated forward-backward translation procedures.
Results: The mean total correct score on the ANSKQ was 12 out of a possible 35 (34.45%). The mean total correct score on the ANSKQ was 12 out of a possible 35 (34.45%). Players had a statistically significantly higher score for “General Nutrition” knowledge than Sports Nutrition Knowledge (47.27% vs 28.53%, p<0.005). Futsal players had infrequent consumption of the food group "Milk and dairy products", and frequent consumption of "Snacks" as well as fruits. Regarding dietary supplements, 46% of athletes said they consume, or previously consumed, with Whey Protein being the most common supplement.
Conclusions: There is room from improvement in athletes nutrition knowledge, especially sports specific knowledge. Futsal players may also require education on appropriate supplement use and dietary intake.

Published: October 2021

A field experiment was conducted once at Isabela State University, Jones, Isabela, Philippines during the wet season of 2018 to determine the impact of seaweed extract added with varying levels of inorganic fertilizer on the growth and yield of upland rice (Oryza sativa L.) cultivars. In the study, five fertilizer levels and a farmer’s practice as a control combined with seaweed extract was used. The study used Randomized Blocks in a Factorial Scheme with six treatments replicated thrice as follows: Factor A: V1-Pinilisa, V2-Palawan and Factor B: F1-150-100 kg NP ha-1 (Farmer’s Practice), F2-40-10 kg NP ha-1 (100% Recommended Rate), F3-20-5 kg NP ha-1 (50% Recommended Rate), F4-40-10 kg NP ha-1 + 3 L/ha. Seaweed extract, F5-20-5 kg NP ha-1 + 3 L/ha. Seaweed extract and F6-3L/ha. Seaweed Extract. The findings revealed that seaweed extract combined with inorganic fertilizer application influenced the growth and yield of rice. Pinilisa cultivar obtained a higher yield compared to the Palawan cultivar. The combination of seaweed extract and inorganic fertilizer shows highly significant differences especially concerning the number of productive tillers, filled grains, 1000 grain weight and straw weight. The return on investment showed that Pinilisa cultivar fertilized with 3 L seaweed extract is more economical in upland rice obtaining the highest with 95.47%. Seaweed extract as foliar fertilizer can be applied not only in rice but also in other crops. Application of seaweed extract on rice can reduce the amount of fertilizers.
